Technical Field

The invention relates to a power supply device, an atomization device and an electronic cigarette assembly assembled by the same.

Background

Conventional e-cigarettes are of both non-removable and removable types. In the detachable conventional electronic cigarette, the air inlet conveying function and the electric conduction function of the atomizing device are respectively borne by different components, and meanwhile, in the power supply device matched with the atomizing device, the electric conduction and the air supply are respectively realized by different components. Such structures often result in poor contact or unstable air supply due to the force applied by the user during use, or require additional components to achieve the reliability of both functions.

Disclosure of Invention

To this end, the present invention aims to provide a power supply device, an atomizing device and an electronic cigarette assembly, which can overcome the problems in the prior art.

Specifically, the present invention provides a power supply device having conductive tabs, wherein at least one of the conductive tabs has a tab air delivery channel. This configuration of the invention allows the integration of the electrical conduction function and the gas supply function, thereby making the structure of the invention more compact. Meanwhile, by integrating the air intake passage into the conductive protrusion, stability of air intake and conduction can also be ensured. In particular, in the prior art, since the power supply unit supplies power and the air supply unit (for example, in a manner of reserving a cavity) are separate units, the assembly process and the use process are prone to deviation, which results in poor contact of the power supply unit or instability of the flow path of the air inlet channel. The mode of the invention overcomes the defects and improves the redundancy and the simplicity in design and assembly.

In a preferred embodiment of the power supply device according to the invention, at least one of the conductive protrusions is located at a non-center of the mating interface. Preferably, there may be two conductive tabs, and both of the two conductive tabs are located off-center, which is preferably symmetrically arranged. It will also be appreciated that the two conductive tabs are concentrically arranged at a non-center location.

In a preferred embodiment of the power supply device according to the invention, at least one of the conductive protrusions is located at the center of the mating interface. Preferably, there may be two conductive protrusions, and the two conductive protrusions may be concentrically arranged at the center.

In a preferred embodiment of the power supply device according to the invention, one of the conductive protrusions is located at the center of the mating interface and the other conductive protrusion is located at the non-center of the mating interface.

By arranging the conductive protrusions concentrically at the center or off-center, the structure according to the invention can also be made more compact.

In a preferred embodiment of the supply device according to the invention, the supply device may have a projection which cooperates with a mating auxiliary air channel possibly provided on the atomizing device, thus acting as a sealed air channel. The auxiliary airway will be described in further detail below with respect to the aerosolization device.

In a preferred embodiment of the power supply device according to the invention, an elastic member may be provided on the conductive protrusion to ensure a reliable electrical connection between the conductive protrusion and the receptacle provided on the atomizer device in the mated state, thereby ensuring a stable electrical output.

In a preferred embodiment of the power supply device according to the invention, the conductive protrusion consists of a top part and a non-top part, the top part being insulated. The raw material of the top part is an insulating material, and the top part and the non-top part are not integrally manufactured; alternatively, the conductive protrusions are made of conductive material and are made of a single body, and the conductive property of the top is transformed into insulation by chemical treatment.

In a preferred embodiment of the power supply device according to the invention, the conductive protrusion may be configured in the shape of a rod, a cone, a boss, or other suitable shape for insertion into the main channel seal.

In a preferred embodiment of the power supply device according to the invention, the tip of the conductive protrusion may additionally be provided with a tip. By providing this tip, the main passage seal portion provided in the atomizing device paired with the power supply device can be pushed open more easily or less forcibly. Meanwhile, the shape of the main channel sealing part after being burst can be more closely surrounded around the conductive protruding part.

In a preferred embodiment of the power supply device according to the invention, the tip may be insulated.

In a preferred embodiment of the power supply device according to the invention, the outlet of the projection air delivery channel of the electrically conductive projection can be arranged at the axial tip or on a side surface near the axial tip for guiding the air flow, in particular for guiding the air flow radially inwards.

In addition, the present invention also provides an atomizing device, and it can be understood that the features and technical effects described above with respect to the power supply device can also be applied to the embodiment with respect to the atomizing device. In particular, the atomizer device according to the invention has electrically conductive receptacles which can be mated with electrically conductive projections of a power supply device, wherein at least one of the electrically conductive receptacles has a receptacle air feed channel. The conductive container thus has both a function of transmitting electric power and a function of conveying air inside.

In a preferred embodiment of the atomizer device according to the invention, the atomizer device has a main channel seal corresponding to the electrically conductive receptacle, wherein in the unmated state of the atomizer device the electrically conductive receptacle is sealed by the main channel seal; and in a mated state of the atomizing device and the power supply device, the main passage seal portion may be inserted and held tightly around the conductive protrusion by the conductive protrusion. By means of this preferred embodiment, an effective sealing of the atomizing device against leakage of oil in the oil cup, both before and during use, can be achieved.

In a preferred embodiment of the nebulizing device according to the invention, the nebulizing device has an auxiliary air channel. The auxiliary air duct can be used to communicate with the air supply passage in the middle of other power supply devices when combined with other power supply devices that do not have conductive protrusions that also serve as air supply passages, and thus can be matched to other power supply devices not according to the present invention. When the power supply device according to the invention, which preferably has a projection, is used, the auxiliary air duct can be closed, so that air supply is ensured only via the projection air supply channel in the electrically conductive projection.

In a preferred embodiment of the atomising device according to the invention the auxiliary air duct may be provided with an auxiliary seal. The auxiliary sealing part is detachable or openable. Thereby, the sealability of the auxiliary air passage can be ensured when being matched with the power supply device according to the invention. Moreover, since the auxiliary sealing part is detachable or openable, the atomization device can also be matched with other power supply devices without a conductive protruding part which is used as an air supply channel at the same time after the auxiliary sealing part is detached or opened.

In a preferred embodiment of the atomizer according to the present invention, the primary channel seal has a chamber, and the housing air delivery channel, the chamber and the smoke exit channel of the atomizer communicate in sequence when one end of the chamber is breached by the conductive projection of the power supply.

In a preferred embodiment of the atomising device according to the invention the bottom of the electrically conductive container may be provided with a recess preventing the electrically conductive protrusion from completely blocking the container air transport channel, whereby the atomising device may be matched to other power supply devices that do not have an electrically conductive protrusion that simultaneously serves as an air supply channel.

In a preferred embodiment of the atomising device according to the invention the main channel seal may be provided with scratches or grooves, thereby facilitating the puncture by the conductive protrusions or tips on the power supply means.

In addition, the invention also provides an electronic cigarette component which is formed by the power supply device and the atomization device, and the characteristics mentioned above about the power supply device and the atomization device and the corresponding technical effects can also be applied to the electronic cigarette component.

Detailed Description

In the following description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific illustrative embodiments in which the present teachings may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present teachings, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present teachings. Accordingly, the following description is to be construed as illustrative only.

Fig. 1 shows an exemplary embodiment of a power supply device (host) 1 according to the invention, in combination with its detailed view 2 and exploded view 3 and its component detailed views 4 and 5, including but not limited to what is shown in the upper left front sectional view of fig. 1: a conductive protrusion (also understood to be an electrode or a battery rod) 11 and a protrusion air delivery channel 12 formed by the conductive protrusion for guiding air from the air inlet 16, which protrusion air delivery channel may be arranged hollow in the conductive protrusion or may be provided in the form of a partial groove for guiding air from the air inlet 16 to or near the tip of the conductive protrusion 11. The conductive tab may also include a transverse channel in transverse communication with the air inlet 16 and a vertical channel. The conductive tab 11 is configured to conduct power from the battery or its electrical control device. Through the integration of power supply connection and air feed connection, the simple degree of assembly has been improved and in the in-process that uses together with the atomizing device that corresponds, reduced because contact failure or air feed unstability that too much power supply connection and air feed connection caused.

It should be understood that although in the figures it is shown that both conductive tabs 11 each have one tab air delivery channel 12, it is also possible to provide a tab air delivery channel 12 in only one of the conductive tabs 11.

It should be understood that although only the conductive protrusions 11 located at both sides and having central symmetry are shown in the drawings, the above positional definition is not essential. A central arrangement of the at least one electrically conductive joint is also possible. For example, one of them is arranged at the center, while the other remains at the side.

In addition, it is also possible as a preferred embodiment that the conductive protrusions 11 may be arranged concentrically, whereby two conductive protrusions 11 may also be located at the center or at the sides at the same time.

In the preferred embodiment shown in fig. 1 in conjunction with detailed view 2, the conductive tab includes a boss 13, and the boss 13 may be used to mate with a secondary air passage 24 of the atomization device 2 of the present invention, thereby acting to seal the secondary air passage 24. Specific details regarding the sealed gas passage will be set forth further below.

Fig. 1, in conjunction with its detail view 2, also shows an elastic element 14, which elastic element 14 is arranged to surround the conductive protrusion 11, while an elastic element housing 15 is arranged on the elastic element 14, which elastic element housing 15 has electrical conductivity, such that in the use state a tight contact between the conductive protrusion 11 and a conductive receptacle 21 of the atomizer device 2 fitted thereto is ensured by the elastic force of the elastic element 14 (see detail view 12 after fitting). It should also be understood that although the resilient member provided is configured as a coil spring, other forms of resilient member are possible, and accordingly other forms of positional relationship between the resilient member 14 and the conductive projection are possible.

Fig. 4 shows various alternative embodiments of the conductive tab and resilient member housing according to the present invention. The upper left embodiment is provided with an end face contact projection 141 on the end face of the elastic member housing 15, which contributes to sufficient electrical contact with the conductive receptacle 21 of the atomizer device 2 in the assembled or used state. The upper right alternative embodiment is then provided with side surface contact bumps 111 on the side surfaces of the conductive protrusions 11. In a preferred embodiment, the contact protrusion 111 may be configured as a ball plunger, and when the conductive protrusion 11 is inserted into the atomization device 2, the contact protrusion 111 is pressed to retract into the body of the conductive protrusion 11. It should be understood that the above locations of the contact bumps are merely illustrative and that extensions from other locations are also included within the scope of the present disclosure. Meanwhile, the lower left drawing of fig. 4 shows the case without the contact projection, where the conductive connection to the conductive receptacle 21 of the atomizer device 2 is made directly by the conductive protrusion 11 and the elastic member 14 and the elastic member housing 15, wherein the lower right drawing of fig. 4 shows an exemplary connection among the conductive protrusion 11, the elastic member 14 and the elastic member housing 15.

It should also be understood that although a cylindrical configuration of the conductive protrusions 11 is shown in the figures, other forms of modification, such as conical, convex, prismatic, are also possible.

It should also be understood that the conductive bump 11 may be provided in two pieces, i.e. with a top and a non-top, wherein the top is insulated; and it should be understood that the two-piece may be a functional two-piece, i.e., the top and non-top are integrally formed and chemically treated to insulate the top. This arrangement still ensures an electrically conductive connection via the elastic element 14 and the elastic element housing 15 to the electrically conductive receptacle 21 of the atomizer device 2.

Fig. 5, in particular the left detailed view of fig. 5, shows an alternative variant according to the invention, in which a tip 17 is provided, by means of which the main channel seal provided in the atomizer device paired with the power supply device can be more easily lifted open. Meanwhile, the shape of the main channel sealing part after being burst can be more closely surrounded around the conductive protruding part. It should be understood that although the tip shown in fig. 5 is sharply angled, other configurations, such as a needle shape, to facilitate puncturing of the seal are possible.

Fig. 6 shows an exemplary embodiment of an atomising device (atomiser or cartridge) 2 according to the present invention, including but not limited to that shown in the upper left front sectional view of fig. 6, in conjunction with its detailed view 7 and exploded view 8 and component view 9: a conductive container 21 (i.e., an atomizer electrode), an oil cup, a mouthpiece, a heater, and the like. By the supply of power through the above-mentioned conductive protrusion 11 and its accessory parts from the power supply device, the conductive receptacle receives power and supplies it to the heating wire for heating the tobacco tar. While the conductive receptacle 21 may at least partially receive the conductive protrusion 11 (and may additionally include its accessories such as the resilient member 14 and the resilient member housing 15) such that air supplied from at least one conductive protrusion 11 may be received by the conductive receptacle 21.

It should be understood that, in correspondence with the conductive tabs 11, the two conductive housings 21 illustrated may be provided with only one of them having a corresponding housing air delivery channel 22. I.e. the supply of air is effected by only one projection air feed channel 12 and receptacle air feed channel 22.

In a preferred embodiment, the atomizer device has a main channel seal 23, as can be seen from fig. 6 in conjunction with the detailed view of fig. 7. The main passage sealing portion 23 may be formed of, but not limited to, sealing silicone. In the unmated state of the atomizing device 2, the conductive housing 21 is sealed by the main channel seal 23; and in the mated state of the atomizing device 2 and the power supply device 1, the main passage seal portion 23 can be inserted and held tightly around the conductive protrusion 11 by the conductive protrusion 11. With this preferred embodiment, the tobacco smoke that accidentally seeps above the conductive receptacle 21 can be sealed inside the atomizer, whether before or during use. At the same time, backflow or seepage of gas in the atomizer into the gap between the atomizer and the power supply or other undesired locations can also be avoided.

It will also be understood that the end surface of the conductive receiving portion 21 contacting the conductive protrusion 11 cannot be inserted into the conductive protrusion 11, and the conductive protrusion 11 can also serve to conductively ventilate the conductive receiving portion 21.

It will also be appreciated that the conductive receptacle 21 may also be arranged centrally and/or off-center, corresponding to the location and configuration described above with respect to the conductive tab 11. While also being adaptively configured to receive the concentrically arranged conductive tabs 11.

In a preferred embodiment, the atomizer device 2 has an auxiliary air duct 24, as can be seen from fig. 6 in conjunction with the detailed view 7. By providing one or more auxiliary air ducts 24, the atomizer device 2 according to the invention can be matched not only to the power supply device 1 according to the invention with conductive protrusions 11 on both sides, but also to other commercial main units, which are typically supplied with air via the middle. That is, since other hosts on the market do not have the conductive protrusion portion having both air supply and conductive functions of the host according to the present invention, the atomization device according to the present invention can be butted against an air supply member such as a groove in the middle of another host on the market by reserving the auxiliary air passage 24, and thus air can be supplied to the atomizer through the auxiliary air passage.

It will be appreciated that the auxiliary airways 24 are not limited to the two shown, i.e. may be 1 or 3 or more.

The atomizer device according to the invention with the auxiliary air duct 24, when being fitted with the power supply device 1 according to the invention, preferably with the projection 13 (see the assembly drawing on the far right in fig. 11 and its detail drawing 12), can then have the auxiliary air duct 24 closed, thus ensuring that air is supplied only via the projection air supply channel in the electrically conductive projection 11 when the power supply device 1 according to the invention and the atomizer device 2 are used simultaneously.

It will be appreciated that the auxiliary airway 24 may have an auxiliary seal that may be used to seal the auxiliary airway. When matched with other main machines on the market, the auxiliary sealing part can be detached or torn or opened, thereby ensuring the sealing before use and the normal air supply during use.

In a preferred embodiment, as shown in fig. 9a, 9b and 9c, the bottom of the conductive receptacle 21 may be provided with a conductive receptacle recess (or notch) 211 that prevents the conductive protrusion 11 from completely blocking the receptacle air delivery passageway 22. In the solutions shown in fig. 9d, 9e and 9f, the atomizer device may not be provided with the receiving portion air supply passage 22, but only with the recess 211 and the auxiliary air passage 24, and in this case, the air entering through the conductive protrusion 11 of the power supply device 1 can only flow through the recess 211 and the auxiliary air passage 24.

It will be appreciated that the conductive receptacle recess 211 may also communicate with the auxiliary air passage 24 for delivering air from the auxiliary air passage via the receptacle air delivery passage 22 of the conductive receptacle 211. In some aspects, the groove may also be an L-shaped air channel structure formed by a blind hole at the bottom of the conductive accommodating part 21 and a through hole penetrating through the conductive accommodating part 21 in the radial direction. It is to be understood that the groove shape is not limited to the illustrated ones, and any channel that facilitates the formation of an air passage using the conductive receiving portion 21 falls within the scope of the present invention. In this way, it is possible to make the atomising device 2 according to the present invention compatible with other hosts on the market.

In a preferred embodiment, the main channel seal 23 may have a seal score or seal groove (not shown) for facilitating puncture by the conductive tab 11 or tip 17 according to the present invention.

It will be appreciated that although only one layer of primary channel seal 23 is shown in the drawings, the primary channel seal 23 may be provided with a chamber (not shown) having an opening which communicates with the smoke outlet passage of the atomiser. In addition, one end of the chamber is used to seal the atomizer, and when the end is breached by the conductive projection of the power supply, the receptacle air delivery passage, the chamber and the smoke outlet passage of the atomizer communicate in sequence.

Fig. 10 shows an assembly flow of the power supply device 1 and the atomizing device 2 according to the present invention, wherein the left drawing shows the state where the two are separated; the middle figure shows the two close together, in which the atomising device 2 has partially entered the housing of the power supply, however it will be appreciated that the housing may also be provided by the atomising device or may be engaged by other means of engagement; the right drawing shows a state where both are assembled, in which the conductive protruding part 11 is inserted into the conductive accommodating part 21 and the main passage sealing part 23 is punctured (if any). Fig. 11 further shows the detailed engagement of the broken line portion in this assembled state.

Figure 12 shows an exploded view of the electronic cigarette assembly 100 including both the power supply device 1 and the aerosolization device 2.

Figure 13 shows the flow of gas in the use state of the e-vaping assembly 100 according to the present invention, through the air inlet 16 and the inlet channel connected thereto, the conductive protrusion 11 (i.e. protrusion air delivery channel 12), the chamber of the main channel seal 23 and to the smoke outlet channel of the atomizer, respectively. The microphone 18 is in communication with the inlet channel or the protruding part air delivery channel 12, the microphone 18 being adjustable in position according to the actual situation and controlling the power supply device to supply power to the conductive protruding part 11 by sensing the air flow.
