Technical Field

The present invention relates to a fragrance display, and more particularly, to an improvement of a fragrance display capable of filling a plurality of fragrance cartridges and emitting a plurality of fragrances.

Background

There are various forms in human communication that correspond to the senses that humans possess. Of which visual and auditory are most commonly used. In contrast, although the sense of smell is actually present in human life, there are few examples of the use thereof for communication. It is generally considered that if the sense of smell is used in addition to the sense of sight and sense of hearing in communication, the communication is more effective and various people can share the experience more deeply.

In view of this, recently, there has been proposed a device which generates a fragrance depending on the situation by operating in cooperation with a device capable of playing video and audio, such as a television receiver, a personal computer, or a game machine. In this specification, such a device that generates fragrance according to occasion is referred to as a fragrance display.

In such a fragrance indicator, if a function of freely switching a plurality of fragrances is not provided, the fragrances cannot be sufficiently utilized. Therefore, it is conceivable to use a plurality of cartridges (referred to as flavor cartridges) each enclosing a preselected flavor generation source (referred to as a flavor source). The plurality of cartridges are loaded into a fragrance display and fragrance is emitted from a desired cartridge. Such a fragrance presenter is disclosed in japanese patent laid-open publication No. 2014-92673.

According to the disclosure of japanese patent application laid-open No. 2014-92673, a hollow fragrance cartridge is prepared and a fragrance source is sealed in the hollow portion. A fragrance channel for releasing fragrance from the inner fragrance source to the outside is provided. An air supply mechanism for supplying air to the hollow part of the fragrance box at a desired timing is provided on the fragrance display side. As a result, the pressure inside the hollow portion increases, and fragrance can be emitted from the fragrance cartridge to the inside of the fragrance display through the fragrance passage. The fragrance passes through a space between the casing and the cover of the fragrance indicator, is guided to an opening provided at the center of the cover or an opening in the vicinity thereof, and is ejected from the fragrance indicator through the opening or the opening.

In addition to the air supply mechanism for releasing the fragrance from these cartridges, an air passage communicating with the opening of the lid is provided. The bottom of the container is provided with a mechanism for releasing air containing no fragrance component. The air from the air discharge mechanism passes near the outlet of the fragrance passage of the fragrance display and flows toward the opening. When the next fragrance is switched after one fragrance is emitted, air containing no fragrance component is emitted from the air emitting mechanism, and the air containing fragrance is blown off and then the next fragrance is emitted. At this time, if air containing no fragrance component is also discharged from the air discharge mechanism, the fragrance from the fragrance indicator is ejected to the outside from the opening of the cover in accordance with the flow of the air. Therefore, the flavor can be switched at an arbitrary timing so as to avoid mixing of the flavors, and the flavor can be brought to a remote place.

According to the fragrance display having the above-described configuration, it is possible to freely switch the fragrance by operating which air supply mechanism. In addition, if the mechanism for releasing air containing no fragrance component is operated at this time, the mixture of fragrance can be prevented. Which air supply mechanism is operated at which timing can be controlled by sending a command to the fragrance indicator from the outside. Therefore, the following excellent effects are obtained: for example, when watching movies, moving pictures, etc., a desired air supply mechanism is operated at a desired timing, and a fragrance can be emitted according to the situation.

In the flavor display device disclosed in japanese patent application laid-open No. 2014-92673, the number of flavor cartridges to be loaded may be increased in order to increase the types of flavors to be generated. However, in the fragrance indicator disclosed in japanese patent application laid-open No. 2014-92673, the fragrance cartridge is arranged on a circumference around a central axis of the fragrance indicator. Therefore, there is a problem that: if the number of fragrance cartridges that can be loaded is increased, this results in an increased housing for the fragrance display. If the fragrance box is reduced, the housing of the fragrance displayer can be prevented from being enlarged. However, if a fragrance cartridge that is common to other fragrance displays cannot be used, various problems may occur.

For example, assume that a user has previously used a scent display that only uses a fixed number of scent cartridges, and the user newly purchases a scent display that uses a greater number of scent cartridges. In this case, the user would naturally think that the previously owned fragrance cartridge can also be used for the new fragrance display. If a previously available fragrance cartridge is not available for a new fragrance display, the user must purchase many new fragrance cartridges.

Detailed Description

In the following description and drawings, the same components are denoted by the same reference numerals. And thus detailed description thereof will not be repeated. In addition, not all of the following embodiments are necessary to practice the present invention. The constituent elements necessary for carrying out the present invention should be determined in accordance with the contents described in the claims.

[ first embodiment ]

< Structure >

Fig. 1 shows an external view of a fragrance displayer 50 according to a first embodiment of the present invention. Referring to FIG. 1, aroma display 50 includes a generally cylindrical shaped housing 60. The housing 60 includes: a base case 62, and a cartridge housing case 64 and a cover 66 sequentially assembled to the base case 62. The cover 66 is detachable from the cartridge accommodating case 64. When the flavor cartridge is loaded in the flavor displayer 50 or removed from the flavor displayer 50 as described later, the cover 66 can be removed from the cartridge housing case 64.

The cover 66 includes a hood having a circular bottom portion in a shape conforming to the upper end of the cartridge accommodating case 64, and an upper surface gently bulging toward the center. The bottom of the cover is fixed to the upper end (end on the lid 66 side) of the cartridge housing case 64. An opening region 68 is formed in the center of the cover of the lid 66, and an opening, which is an outlet for air containing the fragrance from the fragrance cartridge, is collected in the opening region 68. An opening 70 is formed in the opening region 68, the opening 70 having a diameter of about 1/4 degrees of the diameter of the cover 66.

Referring to fig. 2 and 3, in the present embodiment, the base case 62 and the cartridge accommodating case 64 have circular cross sections. A cartridge housing section capable of housing a plurality of flavor cartridges is formed inside the cartridge housing case 64. As shown in fig. 2 and 3 in particular, a duct member 112 is provided at the center of the cartridge housing case 64, and the duct member 112 defines the air flow path 92. A fragrance cartridge collection 90 containing 18 fragrance cartridges is packed around the duct member 112. As will be described in detail later on, the fragrance box assembly 90 is classified into, in the present embodiment: an outer fragrance box group and an inner fragrance box group. These fragrance cartridges are arranged on a circumference centered on the central axis of the cartridge housing case 64. Details of this configuration will be described later. The number of fragrance cartridges is arbitrary. However, since the prior art discloses a structure containing 6 flavor cartridges, in the flavor displayer of the present invention, it is preferable to use at least 6 outer groups of flavor cartridges and at least 1 inner group of flavor cartridges. In this embodiment, the outer group can be loaded with 12 flavor cartridges, and the inner group can be loaded with six flavor cartridges.

Particularly, referring to fig. 3, the lower end of the nozzle 134 forming the opening 70 shown in fig. 1 is disposed at the center of the rear surface (the surface on the cartridge housing case 64 side) of the cover 66. Six pipe fixing members 140 and the like are arranged around the nozzle 134. The tube fixing member 140 fixes a plurality of tubes for guiding the air containing the fragrance emitted from the fragrance cartridge 90 to the vicinity of the opening 70 inside the nozzle 134, respectively, to the cover 66. The structure of the pipe fixing member 140 and the like will be described later. The lower end of the nozzle 134 is connected to the upper end of the pipe member 112. The lower half of the nozzle 134 is conical in shape whose radius gradually narrows as it goes upward, and the upper half is a cylinder whose inner diameter is smaller than that of the lower end and which is open upward. Since the nozzle 134 has such a shape, air flowing into the lower end of the nozzle 134 may be accelerated inside the nozzle 134 and discharged from the opening of the upper end.

In particular, referring to fig. 3, a plurality of openings 130 serving as air intake ports are provided on the lower surface of the base housing 62 as will be described later. A cartridge accommodating case 64 may be assembled to the base case 62. A multi-blade fan 100 is also mounted inside the base housing 62 via a mounting member 102, and the multi-blade fan 100 is a mechanism for discharging air containing no fragrance component. The sirocco fan 100 generates an air flow of air containing no fragrance and sends the air flow to the nozzle 134 provided in the cover 66. A control circuit substrate 104 that can communicate with the outside by wireless communication is also mounted in the base housing 62 through the mounting members 96 and 98. The control circuit substrate 104 is provided with a control circuit for controlling: a multi-blade fan 100, and a plurality of air supply mechanisms for discharging air containing a fragrance component by supplying air into the fragrance box of the fragrance box assembly 90. The air supply mechanism for each cartridge is provided inside the cartridge housing case 64 as described later. A battery, not shown, is also housed in the base case 62 and is a power source for the control circuit board 104.

A duct member 112 is fixed inside the cartridge housing case 64. The duct member 112 defines the air flow path 92 as described above, and the air flow path 92 is directed from the sirocco fan 100 toward the opening 70. In the present embodiment, the center axis of the cartridge accommodating case 64 coincides with the center axis of the duct member 112. A relay board 94 is mounted centrally on a lower portion of the duct member 112, and the relay board 94 has an opening 106. An NFC chip 132 is provided on the lower surface of the relay substrate 94 in correspondence with the position of each fragrance cartridge, and the NFC chip 132 reads each fragrance cartridge or an identifier of the fragrance cartridge by performing near field communication with an NFC tag (not shown) attached to the bottom surface of the fragrance cartridge. The lower end of duct member 112 is disposed near the outlet of multi-blade fan 100 via opening 106.

Referring to fig. 4 and 5, for example, the flavor cartridge 180 has a triangular prism shape with a cross section of a substantially regular triangle. That is, the flavor cartridge 180 has a casing 220, the casing 220 being composed of an upper surface 221, a bottom surface 222, and a side surface 223, wherein the upper surface 221 and the bottom surface 222 are equi-triangular and parallel to each other; the side surfaces 223 are formed to connect the peripheries of the upper surface 221 and the bottom surface 222. The housing 220 has a hollow portion in which a fragrance source can be enclosed. An ejection port 224 is formed near one apex of the upper surface 221 of the fragrance cartridge 180, and the ejection port 224 communicates with the hollow portion of the housing 220, and can discharge air containing fragrance from the fragrance source enclosed in the housing 220. In the present embodiment, if the center of the upper surface 221 is set as the geometric center of the upper surface 221, the injection port 224 is located on a line segment connecting the center of the upper surface 221 and the one vertex described above, the line segment being divided into 4: 1 degree and eccentric from the position on the one vertex side. An air supply port 225 is formed in a portion of the side surface 223 opposite to the ejection port 224, and the air supply port 225 is used for supplying air from a micro blower (described later) as an external air supply mechanism to the hollow portion of the housing 220. As shown in fig. 5, grooves 226 and 227 are formed in side surfaces 223 on both sides of the apex where the ejection port 224 is formed. These grooves 226 and 227 are used for positioning when the flavor cartridge 180 is loaded in the cartridge housing section of the cartridge housing case 64.

Fig. 6 is a view showing the arrangement of the tubes in the vicinity of the opening 70 shown in fig. 1. Referring to fig. 6, the nozzles 134 forming the openings 70 are arranged so as to be concentrated around them as described below: a first set of tubes 280, 282, …, 300, and 302 for a first set of flavor cartridges; the second set of tubes 304, 306, …, 312, and 314 for the second set of flavor cartridges. The ends of these tubes open in openings 70. As shown in fig. 6, the tubes 280, 282, 304; tubes 284, 286, 306; tubes 288, 290, 308; tubes 292, 294, 310; tubes 296, 298, 312; tubes 300, 302, 314 are in each case in groups of three. Details of the mechanism for fixing the tubes to the cover 66 will be described later.

Fig. 7 is a sectional view of the aroma display 50 in the direction 7-7 of fig. 1, and fig. 8 is an enlarged view of the vicinity of the opening region 68. Referring to fig. 7, a micro-blower that generates air flow by operating a piezoelectric element is provided behind the inner peripheral wall of the cartridge housing case 64 at a portion where each of the outer fragrance cartridges is loaded. For example, a micro-blower 230 is provided behind the fragrance box 180 belonging to the outer fragrance box group, and the micro-blower 230 feeds air into the air supply port 225 of the fragrance box 180. Similarly to the flavor cartridge 192 mounted on the opposite side of the flavor cartridge 180, the micro-blower 242 for sending air to the air supply port is provided behind the flavor cartridge 192. Further, the micro-blowers are provided for the flavor cartridges belonging to the outer group and the flavor cartridges belonging to the inner group, respectively, so that air can be supplied to the air supply ports of the flavor cartridges, respectively.

For example, one end of a tube 280 for communicating the ejection opening 224 with the opening 70 is attached in abutment with the ejection opening 224 of the flavor cartridge 180. The tube 280 is mounted to the surface of the cap 66 by the tube mount 140. The pipe fixing member 140 fixes the pipe 280 to the cover 66 so that the other end of the pipe 280 opens into the opening 70 formed in the cover 66. Similarly, the flavor cartridge 192 has one end of a tube 292 attached to its ejection port so as to abut against it. The tube 292 is also attached to the cover 66 by the tube fixing member 146 similar to the tube fixing member 140 so that the other end thereof opens from the peripheral wall of the cover 66 toward the center of the cover 66. With this arrangement, air containing fragrance emitted from fragrance cartridges 180 and 192, respectively, can be directed to opening 70 via tubes 280 and 292, respectively, and emitted toward the center of opening 70. When the air flow generated by the multi-fin fan 100 is ejected from the nozzles 134, the air containing the fragrance may be delivered by the flow of the air ejected from the nozzles 134. As a result, the air containing the fragrance can be sent to a position far from the fragrance displayer 50. When the multi-fin fan 100 is stopped, the air containing fragrance ends up near the opening region 68. As a result, the fragrance can be diffused only in the vicinity of the fragrance indicator 50.

Similarly, the tubes 294, 296, 298, 300, and 302, etc. shown in fig. 7 and 8 are used to guide air containing fragrance ejected from the opening of the corresponding fragrance cartridge in the outer fragrance cartridge group to the opening 70. The tubes 310, 312, and 314 shown in fig. 7 and 8 are tubes for scent cartridges belonging to the inner scent cartridge group as described below.

Fig. 9 is a sectional view of the aroma display 50 in the direction of the arrows 9-9 of fig. 1, and fig. 10 is an enlarged view of the vicinity of the opening region 68. Referring to fig. 9, a micro-blower for generating air flow is provided in a portion of the outer peripheral wall of the duct member 112 in the cartridge housing case 64 where each flavor cartridge belonging to the flavor cartridge group inside is loaded. For example, the flavor cartridge 214 belonging to the inner flavor cartridge group is loaded on the cover 66 toward the opposite side of the outer flavor cartridge group so that the ejection port is located at a position away from the center axis of the cartridge housing case 64. A micro-blower 264 is provided behind the fragrance box 214 (a portion of the side surface where the air supply port 325 is formed), and the micro-blower 264 feeds air into the air supply port 325 of the fragrance box 214. Similarly, in the flavor cartridge 208 mounted on the opposite side of the flavor cartridge 214, the micro-blower 270 for sending air to the air supply port of the flavor cartridge 208 is provided at a position behind the flavor cartridge 208 outside the periphery of the duct member 112.

For example, one end of the tube 314 is attached to the ejection port of the flavor cartridge 214 in an abutting manner. The tube 314 is mounted to the back of the cover of the cap 66 by a tube mount 150. The tube fixing member 150 fixes the tube 314 to the cover 66 so that the other end of the tube 314 opens into the opening 70 formed in the cover 66. Similarly, the flavor cartridge 208 is attached to one end of the tube 308 so that the ejection port is in contact therewith. The tube 308 is also attached to the cover 66 by the tube fixing member 144 so that the other end thereof opens into the opening 70 formed in the cover 66. With this arrangement, air containing fragrance emitted from fragrance cartridges 214 and 208, respectively, is guided to opening 70 via tubes 314 and 308, respectively, and is emitted toward the center of opening 70.

Similarly, the pipes 312 and 310 shown in fig. 10 are used to guide the air containing the fragrance ejected from the ejection opening of the corresponding fragrance cartridge in the inner fragrance cartridge group toward the opening 70. Further, the tubes 290, 292, 294, 296, 298, and 300 shown in fig. 10 are tubes for scent cartridges belonging to the outer scent cartridge group.

As shown in fig. 8 and 10, in the present embodiment, the end portion on the opening 70 side of the tube for the outer fragrance cartridge group is disposed inside the opening 70 on the circumference centered on the central axis on the plane perpendicular to the central axis. Further, the end portion of the tube for the inner fragrance cartridge group on the nozzle 134 side is disposed in the opening 70 on a circumference centered on the central axis on a plane perpendicular to the central axis of the opening 70, similarly to the outer fragrance cartridge group. It should be noted that: the circle is on a plane different from the plane of the circle on which the end of the tube for the outer fragrance cartridge group is disposed. By disposing the end portions of the flavor cartridges on different surfaces in this manner, even when the number of flavor cartridges is large and sufficient space cannot be secured inside the opening 70 to form openings for the flavor cartridges, all of the tubes can be disposed inside the opening 70. Therefore, even if the number of flavor cartridges loaded in the flavor displayer 50 is increased, the space for the opening of the tube can be ensured before reaching a certain number without increasing the diameter of the opening 70.

Fig. 11 and 12 are a perspective view and a plan view, respectively, showing the cartridge accommodating case 64 when the cover 66 is removed from the cartridge accommodating case 64. Fig. 11 and 12 show a state in which the flavor cartridge is not loaded in the casing 60. Fig. 13 is an enlarged view of a part of fig. 12. Fig. 14 and 15 are a perspective view and a plan view of cartridge accommodating case 64 showing a state in which outer group 12 flavor cartridges 180, 182, …, 200, and 202 and inner group 6 flavor cartridges 204, 206, …, 212, and 214 are loaded in cartridge accommodating case 64. Fig. 16 is an enlarged view of a part of fig. 15.

Referring to fig. 11, 12, and 13, in the present embodiment, a cartridge accommodating section including outer cartridge accommodating chambers 350, 352, …, 370, and 372 and inner cartridge accommodating chambers 374, 376, …, 382, and 384 is formed in the cartridge accommodating case 64. The cartridge accommodating chambers are each for accommodating one fragrance cartridge. Of these cartridge storage chambers, the cartridge storage chambers 350, 352, …, 370, and 372 are disposed at positions rotationally symmetrical about the center axis of the lid 66, and form outer cartridge storage portions. These cartridge accommodating chambers each form a regular triangular space, and one apex of each of the spaces faces the central axis side of the cover 66. On the other hand, the cartridge accommodation chambers 374, 376, …, 382, and 384 are similarly regular triangular cavities of the same size. However, one vertex of each of the cartridge accommodating chambers 374, 376, …, 382, and 384 is disposed at a position rotationally symmetrical about the central axis of the lid 66 so as to face the opposite side of the central axis, and forms an inner cartridge accommodating portion. Each of these regular triangles has the same distance from the center axis of each of the outer cartridge accommodating chambers 350, 352, …, 370, and 372 if the center thereof is taken as the geometric center. The distance from the geometric center of the regular triangle of the cartridge accommodating chamber to the central axis is referred to as the distance between the cartridge accommodating chamber and the central axis. The distances from the respective inner cartridge accommodating chambers 374, 376, …, 382, and 384 to the central axis are also the same. The distance from the outer cartridge accommodating chamber to the central axis is larger than the distance from the inner cartridge accommodating chamber to the central axis.

Referring to fig. 13, for example, a cartridge accommodating chamber 374 is formed between the cartridge accommodating chamber 350 and the cartridge accommodating chamber 352. The cartridge accommodating chamber 372 is provided adjacent to the cartridge accommodating chamber 350, and no inner cartridge accommodating chamber is formed therebetween. In order to distinguish these, a total of 6V-shaped partition members 400, 404 and the like are provided inside the cartridge housing case 64 to distinguish the outside cartridge housing chambers between which the inside cartridge housing chamber is not provided. The V-shaped opening side end portions of the partition members 400, 404 and the like are fixed to the outer periphery of the duct member 112 via fixing members 414, 416 and the like. Between the cassette storage chambers such as the cassette storage chamber 350 and the cassette storage chamber 352, in which the cassette storage chamber 374 is formed, 6 inverted a-shaped partition members 402, 406, and 408 are provided. The legs of the end portions of the inverted-a-shaped opening side are joined to the upper ends of the adjacent partition members 400 and the like and fixed to the outer periphery of the duct member 112 by fixing members 414, 416 and the like. As shown in fig. 13, 12 micro blowers 230, 232, …, 250, and 252 are fixed to the inner periphery of the outer wall of the cartridge accommodating case 64 so as to match the position of the air supply port of the flavor cartridge accommodated in the cartridge accommodating chambers 350, 352, …, 370, and 372. Further, 6 micro blowers 260, 262, …, 268, and 270 are fixed to the outer periphery of the outer wall of the duct member 112 so as to match the position of the air supply port of the flavor cartridge accommodated in the cartridge accommodation chambers 374, 376, …, 382, and 384.

Further, the micro blowers 230, 232, …, 250, and 252 and the micro blowers 260, 262, …, 268, and 270 are applied with an alternating voltage to generate wind. The ac voltage is generated and output by a control circuit provided on the control circuit board 104 (see fig. 2 and 3). The control circuit appropriately controls the micro blowers 230, 232, …, 250, and 252 in accordance with information acquired from the outside via wireless communication; micro blowers 260, 262, …, 268, and 270; the multiple-blade fan 100 is driven.

As shown in fig. 13, 14, and 15, flavor cartridges 180, 182, …, 200, and 202 (see fig. 14 and 15) can be loaded in the outside cartridge storage chambers 350, 352, …, 370, and 372 (see fig. 13), respectively. Flavor cartridges 204, 206, …, 212, and 214 (see fig. 14 and 15) can be loaded into cartridge storage chambers 374, 376, …, 382, and 384 (see fig. 13) inside. Fig. 7 shows a sectional view in the direction of the arrow 7-7 in fig. 15, and fig. 9 shows a sectional view in the direction of the arrow 9-9 in fig. 15 (although the cover 66 is not shown in both fig. 7 and 9). Of these flavor cartridges, flavor cartridges 180, 182, …, 200, and 202 belonging to the outer group are loaded in cartridge accommodating case 64 such that the upper surfaces thereof are aligned on the same plane. The flavor cartridges 204, 206, …, 212, and 214 belonging to the inner group are also loaded in the cartridge housing case 64 such that the upper surfaces thereof are aligned on the same plane. In the present embodiment, the surface on which the upper surface of the flavor cartridge belonging to the outside group is disposed is the same as the surface on which the upper surface of the flavor cartridge belonging to the inside group is disposed, but these surfaces may be different from each other.

Fig. 16 shows the planar positional relationship between the fragrance cartridge of the outer group and the fragrance cartridge of the inner group. Referring to fig. 16, the centers of the flavor cartridges of the outer group (e.g., center 420 of flavor cartridge 180, center 422 of flavor cartridge 182, etc.) all lie on a first circle 430 centered on the central axis 428 of cartridge receiving case 64. The first circle 430 is a circle having a radius R1. Likewise, the center of the flavor cartridges of the inner group (e.g., center 424 of flavor cartridge 204) resides on a second circle 432 centered about the central axis 428. The second circle 432 is a circle of radius R2. Clearly, R1 > R2.

Further, the ejection ports of the flavor cartridges of the outer group (for example, the ejection ports 224 of the flavor cartridges 180) and the like are present on a third circle 434 having a radius R3 with the center axis 428 as the center. Similarly, the ejection ports of the flavor cartridges of the inner group (e.g., the ejection ports 426 of the flavor cartridges 204) are present on a fourth circle 436 having a radius R4 centered on the central axis 428.

Further, the vertex of the flavor cartridge of the outer group closest to the ejection opening is present on the fifth circle 438 having a radius R5 centered on the central axis 428. Similarly, the apex of the flavor cartridge of the inner group closest to the ejection opening is located on the sixth circle 440 having a radius R6 centered on the central axis 428.

In the case where R5 is R6, the apexes of the flavor cartridges closest to the ejection opening exist on the same circle. In the cartridge accommodation case 64, 18 cartridges can be accommodated. However, the distance from the outer periphery of the duct member 112 to the inner periphery of the cartridge accommodating case 64 is substantially equal to the sum of the heights of the two flavor cartridges and the heights of the two micro blowers. If R5 > R6, the distance is further increased, which is disadvantageous in making the cartridge accommodating case 64 compact. Therefore, R5 ≦ R6 is preferred. On the other hand, it is preferable that the distances from the respective flavor cartridges to the opening 70 are equal to each other. If the distance difference is large, it is not preferable to cause a difference in timing of ejecting the air containing the fragrance. Therefore, R3 is preferably about R4. The absolute value of the difference between R3 and R4 is preferably within a range of 10% or less of the height of the regular triangle in the plane of the flavor cartridge. More preferably, the absolute value is within a range of about 5% or less. In addition, R4 > R3 is preferable for making the cartridge housing case 64 more compact. The relationship between R3 and R4 in this case will be described in the second embodiment.

Fig. 17 shows a perspective view of the back of the cover 66. Referring to fig. 17, six pipe fixtures 140, 142, …, 148, and 150 provided at six positions, respectively, are fixed to the back surface of the cover 66. In fig. 17, a state is shown in which only the tube fixing members 140 thereof are detached from the cover 66. These tube holders 140, 142, …, 148 and 150 are used to group one of the 6 flavor cartridges on the inside with the two outer flavor cartridges adjacent to it and to hold the tubes for them to the lid 66, respectively. In the example shown in fig. 17, the tube fixing member 140 is used to fix the flavor cartridge 204 shown in fig. 15 and the tubes 304, 280, and 282 (see fig. 6) of the two outer groups of flavor cartridges 180 and 182 adjacent thereto to the lid 66 centering on the flavor cartridge 204. As shown in fig. 17, the pipe fixtures 140, 142, …, 148, and 150 are arranged at six rotationally symmetric positions around the center of the cover 66, that is, the center of the nozzle 134 (fig. 6).

Referring to fig. 18 to 20, for example, the pipe fixing member 140 includes: a first member 500 formed with a groove 520 and a screw hole 540; and a second member 502 having a groove 522 and a screw hole 542 formed in a surface on the first member 500 side, and a groove 524 formed in a surface opposite to the surface. Two small projections 570 and 572 are formed on the surface of the first member 500 on the second member 502 side, and two small recesses, not shown, are formed at corresponding positions on the surface of the second member 502 on the first member 500 side. Threaded holes 580 and 582 are formed between both side surfaces of the first member 500, and threaded holes 584 and 586 are formed at corresponding positions on both side surfaces of the second member 502. The first member 500 and the second member 502 are combined between the groove 520 and the groove 522 in such a manner as to clamp the tube 280. In this example, the first member 500 and the second member 502 are coupled to each other by fitting the protrusions 570 and 572 formed on the first member 500 into the recess formed on the surface of the second member 502. When the first member 500 is thus coupled to the second member 502, the screw holes 540 and 542 form screw holes into which the screws 510 are inserted.

The tube fixing member 140 further includes: a third member 504 having a groove 526 formed in a surface on the second member 502 side and a groove 528 and a screw hole 544 formed in a surface on the opposite side; and a fourth member 506 having a groove 530 and a screw hole 546 formed in a surface thereof on the third member 504 side. Small protrusions 574 and 576 are formed on the fourth member 506 side surface of third member 504, and a small recess, not shown, is formed on the third member 504 side surface of fourth member 506. And small threaded holes 588 and 590 and threaded holes 592 and 594 are formed between both side surfaces of the third member 504 and the fourth member 506, respectively. The third member 504 and the fourth member 506 are combined with each other so as to clamp the pipe 282 between the third member 504 and the fourth member 506. At this time, third member 504 and fourth member 506 are coupled by fitting protrusions 574 and 576 formed on third member 504 into the recess formed in fourth member 506. When the third member 504 is thus coupled to the fourth member 506, threaded holes into which the screws 512 are inserted are formed by these threaded holes 544 and 546.

Finally, the coupling members of the first member 500 and the second member 502 and the coupling members of the third member 504 and the fourth member 506 are combined so as to sandwich the pipe 304 between the groove 524 of the second member 502 and the groove 526 of the third member 504, and the screw holes 580, 582, …, 592, and 594 are inserted to couple these members to each other, thereby obtaining the pipe fixing 140.

The pipe fixing 140 is fixed to the back surface of the cover 66 by inserting the screws 510 and 512 into the screw holes formed in the pipe fixing 140 and further screwing the screws 510 and 512 into the screw holes formed in the back surface of the cover 66.

Referring to fig. 19 and 20, the grooves 520 and 522 are formed in advance by: when the tube fixing member 140 is fixed to the cover 66, one end of the tube 280 abuts against the ejection opening 224 (see fig. 4) of the corresponding flavor cartridge 180, and the other end 560 opens into the opening 70. The grooves 524 and 526 are also similarly formed in advance so that one end of the tube 304 abuts against the ejection port of the corresponding flavor cartridge, and the other end 564 opens into the inside of the opening 70. The grooves 528 and 530 are also formed so as to be positioned in advance in such a manner that one end of the tube 282 abuts against the ejection port of the corresponding flavor cartridge, and the other end 562 opens into the opening 70. As shown in fig. 19 and 20, the ends 560 and 562 are positioned in such a way that they are at the same height when the tube holder 140 is secured to the cap 66. The ends 564 are pre-positioned in a slightly lower position than the positions of the ends 560 and 562.

The same is true for the other tube mounts 142, 144, …, 148, and 150, and therefore a detailed description thereof will not be repeated here.

The tube 280 may be formed of a common resin, such as polyethylene, polypropylene, polyethylene terephthalate, acrylic, polyvinyl chloride, polycarbonate, and the like. In the present embodiment, a fluororesin (e.g., polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, perfluoroalkoxyalkane, perfluoroethylene-propylene copolymer, polyvinylidene fluoride, polychlorotrifluoroethylene, ethylene-chlorotrifluoroethylene copolymer) is further coated on the inner wall of the tube 280 or the like. The fluororesin has a property of being smooth and not easily adhering to substances as is well known. When the air containing the fragrance is discharged to the outside by such a tube, it is difficult to attach the fragrance substance to the inside of the tube. Therefore, there is an effect of preventing a problem that even when the flavor cartridge is replaced, the original flavor from the flavor cartridge is mixed with other flavors attached to the flavor displayer 50.

Further, not only the coating of the fluororesin on the inner wall of the resinous tube has an effect, but also the molding of the tube with a general resin mixed with the fluororesin has an effect.

The above-described fragrance displayer 50 operates as follows. In order to use the flavor presenter 50, a flavor cartridge such as the flavor cartridge 180 is required to be initially loaded into the cartridge housing case 64. In the present embodiment, the outer group of 12 flavor cartridges 180, 182, …, 200, and 202; the 6 flavor cartridges 204, 206, …, 212, and 214 in the inner group are loaded in the cartridge housing case 64. That is, up to 18 scent cartridges can be loaded in scent display 50. After the flavor cartridge is loaded in the flavor display 50, the NFC chip 132 inside the flavor display 50 reads the flavor cartridge or the identifier of the flavor from an NFC tag, not shown, on the flavor cartridge by near field communication. The identifier is transmitted to an external control device (e.g., a computer) via the control circuit board 104. Based on this information and the scenario description prepared in advance, the external control device generates a control signal relating to: the timing at which the fragrance is ejected from which fragrance cartridge, when the multi-blade fan 100 is operated, and the like. The control circuit board 104 supplies the control signal to the micro blowers 230, 232, …, 250, and 252 corresponding to the designated flavor cartridge at the timing designated by the control signal; micro blowers 260, 262, …, 268, and 270; the multi-bladed fan 100 sends a drive signal. The micro blower 230, 232, …, 250, or 252 receiving the driving signal; or a micro-blower 260, 262, …, 268, or 270; alternatively, the multi-blade fan 100 is operated in accordance with the drive signal to eject the air containing the fragrance from the fragrance box. In this case, two or more micro blowers may be driven simultaneously, or only one micro blower may be driven. In addition, the micro blowers 230, 232, …, 250, or 252; or the micro blowers 260, 262, …, 268 or 270 may drive the multi-blade fan 100 at the same time, or only the desired micro blowers 230, 232, …, 250 or 252 may be driven without driving the multi-blade fan 100; or a micro-blower 260, 262, …, 268, or 270. Further, the micro blowers 230, 232, …, 250, and 252 may not be driven; micro blowers 260, 262, …, 268, and 270 only drive the multi-bladed fan 100.

More specifically, referring to fig. 7, for example, when fragrance is ejected from the fragrance cartridge 180 belonging to the outer group, the control circuit board 104 applies an ac voltage to the piezoelectric element inside the micro blower 230 corresponding to the fragrance cartridge 180. The piezoelectric element inside the micro blower 230 vibrates in response to the ac voltage, and the thin plate to which the piezoelectric element is attached vibrates to generate air flow. The air is blown from the nozzle of the micro-blower 230 into the inside of the flavor cartridge 180 through the air supply port 225 (see fig. 4) of the flavor cartridge 180. As a result, the pressure inside the fragrance cartridge 180 is temporarily increased, and the fragrance cartridge 180 responds to the increase in pressure, thereby ejecting the air containing the fragrance from the fragrance source enclosed inside to the outside from the ejection port 224.

Referring particularly to fig. 21, the air utilized by the micro-blower 230 enters the housing 60 through the opening 130 formed in the bottom surface of the base housing 62 and then reaches the position of the micro-blower 230 via the air flow channel 600. Further, the air is sucked into the micro-blower 230, and intermittently blown into the inside of the flavor cartridge 180 through an air flow path 604 constituted by a nozzle of the micro-blower 230 and an air supply port 225 (refer to fig. 4) of the flavor cartridge 180. The pressure of the hollow portion of the fragrance cartridge 180 repeatedly rises temporarily in response to the blowing of air. In response to this pressure increase, air containing fragrance from the fragrance source enclosed in the hollow portion of the fragrance cartridge 180 is ejected from the ejection port 224 (see fig. 4) of the fragrance cartridge 180. The ejected air 608 containing fragrance enters the inside of the tube 280 from one end of the tube 280, is guided to the nozzle 134 side through the tube 280, and is ejected as air 612 containing fragrance toward the inside of the opening 70 from the other end of the tube 280.

The ejection of the air 612 containing the fragrance is repeated while the ac voltage is applied to the micro-blower 230. When the application of the ac voltage to the micro-blower 230 is stopped, the micro-blower 230 stops operating and stops blowing air into the fragrance cartridge 180. As a result, the ejection of the air containing the fragrance from the fragrance cartridge 180 is stopped. Therefore, by controlling the timing of starting and stopping the application of the ac voltage to the micro-blower 230, the desired fragrance can be emitted from the fragrance displayer 50 at a desired timing and for a desired time.

At this time, if the multi-fin fan 100 is operated, the flow 620 of air generated by the multi-fin fan 100 enters the inside of the nozzle 134 from the air flow passage 92 in the duct member 112, is accelerated due to the narrowing of the inner diameter of the upper portion of the nozzle 134, and is ejected to the outside of the fragrance displayer 50 as the ejection air 622. At this point, air 612 containing the scent is drawn into the ejected air 622 and transported away with the ejected air 622. If the multi-bladed fan 100 is not operating, the scent-containing air 612 is only ejected near the scent display 50, where it stops if there is no other wind. Thereafter, if the multi-blade fan 100 is operated, the fragrance that has previously stopped near the fragrance displayer 50 is dissipated.

As for the other flavor cartridges of the outer group, for example, in the case of the flavor cartridge 192, the same is true, and the air taken in from the opening 130 is sucked into the micro blower 242 of the flavor cartridge 192 via the air flow passage 602 and blown into the interior of the flavor cartridge 192. As a result, the air 610 containing fragrance is guided to the nozzle 134 side via the tube 292, and is ejected from the other end of the tube 292 into the opening 70 as the air 614 containing fragrance. Thereafter, the operation of the air containing fragrance is the same as in the case of the fragrance cartridge 180.

When the air containing the fragrance is ejected from the fragrance cartridge in the inner group, for example, the fragrance cartridge 214, the fragrance presenter 50 operates as follows. Referring to fig. 22, an ac voltage is applied to a micro-blower 264 disposed between the flavor cartridge 214 and the duct member 112. In response to this ac voltage, the micro-blower 264 takes in air taken in from the opening 130 into the casing 60 through the paths such as the air flow paths 600, 640, and 644 and intermittently blows the air into the fragrance cartridge 214, similarly to the micro-blower 230 shown in fig. 21. As a result, the pressure inside the flavor cartridge 214 repeatedly rises temporarily. In response to the pressure increase, scent cartridge 214 causes air containing scent from the scent source enclosed therein to be ejected from ejection opening 324.

The air 648 containing the fragrance enters the tube 314 from one end of the tube 314, is guided to the nozzle 134 side through the tube 314, and is ejected from the other end of the tube 314 into the opening 70 as the air 652 containing the fragrance. Since the operation of the flavor display 50 is the same as that when the flavor cartridge of the outer group is operated, the description thereof will not be repeated.

In fig. 22, the same applies to the operation of the flavor cartridge 208 disposed in the inner group on the opposite side of the flavor cartridge 214 via the duct member 112. By driving the micro-blower 270, the air 650 containing the fragrance is ejected from the cartridge 208 into the opening 70 as the air 654 containing the fragrance via the tube 308. Thereafter, the operation of the flavor displayer 50 is the same as that when the flavor cartridge of the outer group is operated and that when the flavor cartridge 214 is operated, and therefore, the description thereof will not be repeated.

As described above, according to the present embodiment, a plurality of flavor cartridges are attached to the flavor display 50, and air containing flavor can be ejected from any flavor cartridge. These flavor cartridges are all of the same shape and the same structure, and the flavor cartridge belonging to the outside group is not different from the flavor cartridge belonging to the inside group. Therefore, these scent cartridges can be used if they are of the same type as those used in commercially available scent displays. Further, the fragrance cartridges are divided into the outer group and the inner group, so that the space in the casing can be effectively used, the casing can be prevented from being enlarged as much as possible, and a large number of fragrance cartridges can be used. As a result, it is possible to provide a flavor display device that uses a flavor cartridge having versatility without using a dedicated flavor cartridge, and that can eject desired flavor using a large number of flavor cartridges while preventing the size of the casing from increasing.

Since the inner wall of the tube 280 and the like is coated with the fluorine resin, for example, air containing the fragrance discharged from the fragrance cartridge 180 can be efficiently guided to the nozzle 134 side and discharged. After the fragrance is stopped from being ejected from the fragrance cartridge 180, substantially no fragrance component adheres to the inner wall of the tube 280. And thus has the effect of preventing the problem of causing the fragrance to be mixed when the fragrance cartridge 180 is replaced with another fragrance cartridge. Even if a fragrance component remains in the tube 280, the fragrance can be quickly discharged from the tube 280 when the fragrance indicator 50 is operated next time. Therefore, even when the flavor cartridge 180 is stopped and the flavor is ejected from another flavor cartridge, the remaining flavor component does not substantially cause an adverse effect.

Even when fragrance adheres to the inside of the tube 280 or the like due to long-term use of the fragrance indicator 50, any tube can be replaced with a new one by detaching and disassembling the tube holder 140 or the like from the cap 66. Therefore, the following effects are provided: basically, no problem is caused by attaching the fragrance to the inside of the tube, and the desired fragrance can be always generated. In addition, the 18 fragrance cartridges are divided into 12 outer groups and 6 inner groups and housed in the cartridge housing case 64. Therefore, the following effects are provided: the user can distinguish the fragrance box of the outer group from the fragrance box of the inner group for use. For example, a user can easily replace the flavor cartridge by loading the flavor cartridge containing the flower-like flavor in the inner group and loading the flavor cartridge containing the other flavor than the flower-like flavor such as coffee and mint in the outer group in such a manner that the flavor cartridge is used while being distinguished from the inner group.

The fragrance display of the first embodiment described above can use a maximum of 12 outside groups of fragrance displays and a maximum of 6 inside groups of fragrance cartridges. That is, the number of fragrance cartridges belonging to the outside group and the number of fragrance cartridges belonging to the inside group were 2: 1. however, the present invention is not limited to such an embodiment. The ratio of the two may be other than 2: 1.

fig. 23 and 24 show a perspective view of the cartridge housing case 710 and the base case 712 of the flavor display unit 700 according to the second embodiment, and a plan view of the cartridge housing case 710, respectively. Referring to fig. 23 and 24, the cartridge housing case 710 includes a cartridge housing portion capable of housing the 12 flavor cartridges 180, 182, …, 200, and 202. The box containing part comprises: an outer box accommodating part for accommodating 6 outer fragrance boxes 180, …, 190; and inner box accommodating portions for accommodating 6 inner flavor boxes 192, …, 202. These flavor cartridges 180, …, 202 are the same as those used in the first embodiment.

The 6 flavor cartridges 180, …, and 190 housed in the outer cartridge housing section are all disposed at six positions rotationally symmetrical about the center axis of the cartridge housing case 710 such that the flavor ejection ports face the center axis direction of the cartridge housing case 710 and such that the air supply ports face the outer peripheral side of the cartridge housing case 710. The 6 flavor cartridges 192, …, and 202 housed in the inner cartridge housing section are all disposed at six positions rotationally symmetrical about the center axis of the cartridge housing case 710 such that the flavor ejection port faces the outer peripheral side of the cartridge housing case 710 and the air supply port faces the center axis of the cartridge housing case 710. A micro-blower for blowing air into each flavor cartridge is provided at the air supply port of each flavor cartridge 180, …, 202.

The fragrance presenter 700 includes a cover (not shown) for covering the cartridge receiving case 710, which is the same as the cover 66 shown in fig. 1 to 3 and fig. 17 of the first embodiment. A tube (not shown) for guiding fragrance from the ejection port of the fragrance cartridge 180, …, 202 to the inside of the opening (the same configuration as the opening 70 in fig. 1) in the center of the lid is fixed to the surface of the lid on the cartridge housing case 710 side by a tube fixing member (not shown) like the tube fixing member 140 (see fig. 17) of the first embodiment.

The other parts of the cartridge housing case 710 of the second embodiment are the same as the fragrance displayer 50 of the first embodiment.

Unlike the fragrance display 50 of the first embodiment, the fragrance display 700 of the second embodiment can store only 12 fragrance cartridges in the cartridge storage case 710, but the cartridge storage case 710 has a smaller diameter and is more compact than the first embodiment.

In addition, by dividing the 12 flavor cartridges into the outer group and the inner group in this way, the user can use the flavor cartridges loaded in the outer group and the flavor cartridges loaded in the inner group separately, which is similar to the first embodiment.

The fragrance displayer of the first embodiment described above may use up to 12 outer sets of fragrance cartridges and up to 6 inner sets of fragrance cartridges. In addition, in the fragrance displayer according to the second embodiment, a maximum of 6 fragrance cartridges can be used for both the outer group and the inner group. However, the present invention is not limited to such an embodiment. The number of cartridges in the outer set and inner set may be other numbers. The number of cartridges to which the two groups belong does not have to have a common divisor, and for example, 5 cartridges may be loaded in the inner group and 14 cartridges may be loaded in the outer group. It should be noted that: in order to effectively utilize the internal space of the casing 60, it is preferable that the number of flavor cartridges of the outer group be larger than the number of flavor cartridges of the inner group as in the first embodiment. In addition, in order to effectively utilize the space between the box to which a group belongs and the box adjacent thereto, it is preferable that the numbers of the two have common divisor.

In addition, in order to fix the tube corresponding to each flavor display to the cover 66 by a tube fixing member such as the tube fixing member 140, it is preferable that a plurality of tubes be fixed to one tube fixing member. In this case, in order to make the tube fixing members have the same structure, it is preferable to fix the structure of the tubes fixed by the respective tube fixing members. That is, it is preferable that each tube fixing member fixes a fixed number of tubes of the flavor cartridge of the outer group and a fixed number of tubes of the flavor cartridge of the inner group. As a result, it is preferable that the ratio of the total number of flavor cartridges of the outer group to the total number of flavor cartridges of the inner group is M: n (wherein M, N is a natural number satisfying M ≧ N, and preferably a natural number satisfying M > N and each being a prime number). In this case, all the tube fixing structures can be made the same as long as each tube fixing member fixes the M tubes for the outer group and the N tubes for the inner group to the cover 66 at the same time. In the first embodiment, M is 2, N is 1; in a second embodiment, M ═ N ═ 1. Of course, multiples of the tubes may be secured by tube fasteners.

In the first and second embodiments described above, a micro-blower is used to discharge a component containing a fragrance from each fragrance cartridge, and a piezoelectric element is used in the micro-blower. However, the present invention is not limited to such an embodiment. For example, a small fan may be used instead of the micro blower. In the above embodiment, a multi-fin fan is used to generate a flow of air without containing fragrance. However, the present invention is not limited to such an embodiment, and other types of fans may be used. For example, a propeller fan or a turbo fan may be used.

In the first embodiment, the tubes for the flavor cartridges belonging to the outer group are opened at equal intervals on a circle in a plane perpendicular to the central axis of the nozzle 134 (i.e., the central axis of the opening 70 and the housing 60) of the side wall of the nozzle 134. Similarly, the tubes for the flavor cartridges belonging to the inner group are opened at equal intervals on a circle in a plane perpendicular to the central axis of the nozzle 134 on the side wall of the nozzle 134. The surfaces on which the openings of the tubes of the outer group are arranged and the surfaces on which the openings of the tubes of the inner group are arranged are different from each other. By configuring in this way, the following effects are obtained: even in a case where it is difficult to provide the openings of the tubes for all fragrance groups on a circle in the same plane of the side wall of the nozzle 134, the positions where the openings are formed can be secured. Preferably, each of the flavor cartridges belonging to the same group can emit the flavor under the same condition. However, the present invention is not limited to the above embodiment, and all the openings for all the tubes may be provided on the same surface as long as the openings can be arranged on the side wall of the nozzle 134. In addition, when the circumferential length of the side wall of the nozzle 134 is short and the number of flavor cartridges is large, the openings of the flavor cartridges may be provided on three or more surfaces.

In the above embodiment, the openings of the tubes for the flavor cartridges belonging to each group are all disposed in the nozzle 134. However, the present invention is not limited to such an embodiment. For example, an end of a tube used for some or all of the groups for ejecting air containing fragrance may be disposed on the surface of the cover 66 near the opening 70 inside the opening region 68 shown in fig. 1.

The embodiments disclosed herein are merely examples, and the present invention is not limited to the above-described embodiments. The scope of the present invention is shown by the claims of the present application with reference to the description of the details of the invention, and includes all modifications within the meaning and scope equivalent to the description of the invention.
