Technical Field

The invention relates to a power supply device of an aerosol generator and the aerosol generator using the power supply device of the aerosol generator.

Background

The aerosol generator comprises an atomizing device for atomizing the tobacco tar into aerosol and a power supply device for providing power for the atomizing device. The power supply device is provided with a mechanical key switch or a pneumatic switch to trigger the power supply device. When the aerosol generator provided with the mechanical switch is used, a user can control the atomization device to atomize the tobacco tar by pressing the mechanical switch while inhaling; however, when using an aerosol generator configured with a pneumatic switch, the user need only inhale to generate the aerosol. Aerosol generators equipped with pneumatic switches are widely appreciated by users as they are more convenient and faster to use.

The existing mechanical key switch or pneumatic switch is welded on the circuit board, and the locking of the key is realized through the circuit on the circuit board. However, due to the miniaturization development of the aerosol generator, sufficient space for arranging the circuit board cannot be reserved inside the aerosol generator. Many small or disposable aerosol generators exist that are configured with only a pneumatic switch that can be triggered by a user as long as the user draws on the aerosol generator, thereby powering the atomizing device. This is easily to cause the aerosol generator to be triggered by mistake, which raises a safety problem.

Thus, the prior art is yet to be improved and enhanced

The invention provides a power supply device of an aerosol generator, which comprises a shell 1, a pneumatic switch component 2 with a conductive elastic sheet 22, a key component 3, a first contact element 4 and a second contact element 5, wherein one end of the first contact element 4 and one end of the second contact element 5 are accommodated in the shell 1, the other end of the first contact element 4 and one end of the second contact element 5 extend out of the shell 1 to be electrically contacted by an external load, the key component 3 is slidably arranged in the shell 1, the pneumatic switch component 2 is arranged in the shell 1, and the conductive elastic sheet 22 is positioned between the key component 3 and the second contact element 5, as shown in figures 1-5. When the key assembly 3 slides to the first position relative to the housing 1, the key assembly 3 applies pressure to the conductive elastic sheet 22, so that the conductive elastic sheet 22 elastically abuts against the second contact member 5. When the key assembly 3 slides to the second position relative to the housing 1, the pressure is released from the key assembly 3, and the conductive elastic sheet 22 rebounds to separate from the second contact member 5. In the embodiment, the elasticity of the conductive elastic sheet 22 is utilized to enable the conductive elastic sheet to be separated from or contacted with the second contact element 5 in the sliding process of the key assembly 3, so that the pneumatic switch is locked or unlocked, the pneumatic switch is prevented from being triggered by mistake, and the use safety of the aerosol generator is improved.

In this embodiment, referring to fig. 2-3, the pneumatic switch assembly 2 includes a pneumatic switch body 21 and the conductive elastic sheet 22. A first lead (not shown) electrically connected with the first contact element 4 is led out from one end of the pneumatic switch body 21, and a second lead is led out from the other end of the pneumatic switch body and electrically connected with the conductive elastic sheet 22. Preferably, the pneumatic switch body 21 is an integrated circuit type pneumatic switch. Namely, the micro control circuit is integrated in the pneumatic switch body 21, so that a control circuit board does not need to be arranged in the shell 1, the cost can be saved, the structure in the power supply device is simplified, and the power supply device is convenient to develop towards miniaturization.

As shown in fig. 4, the housing 1 has a hollow structure with a through hole 12 formed at one side thereof, and a mounting plate 11 facing the through hole 12 is disposed in the housing 1. The mounting plate 11 divides the space in the body into two parts, and the two spaces are respectively positioned at two sides of the mounting plate 11. The space on one side is a closed space for mounting the pneumatic switch body 21, the first contact member 4 and the second contact member 5. Correspondingly, a mounting seat for fixing the pneumatic switch body 21 is arranged in the shell 1. The first contact member 4 comprises a first contact post, the first contact post penetrates through the housing 1, one end of the first contact post extends into the closed space, and the first contact post is welded with the first lead. The mounting plate 11 faces the other side of the through hole 12 to form a mounting groove 13 with the casing 1, and the key assembly 3 is slidably mounted in the mounting groove 13 and partially extends out of the casing 1 from a notch of the mounting groove 13 (i.e., the through hole 12).

Referring to fig. 1 to 3, the second contact member 5 includes a second contact post 51, the second contact post 51 is spaced apart from the first contact member 4 and penetrates through the housing 1, one end of the second contact post extends into the mounting groove 13, and the other end of the second contact post extends out of the housing 1. Preferably, one end of the second contact column 51 extending into the mounting groove 13 is attached to the mounting plate 11. When the conductive elastic sheet 22 is elastically abutted against the second contact column 51 under the action of the key assembly 3, the mounting plate 11 can support the second contact column 51 to prevent the second contact column 51 from shaking, thereby causing the problem of poor contact between one end of the extending casing 1 and an external load.

In the preferred embodiment of the present invention, as shown in fig. 2-3, the second contact member 5 further comprises a conductive pole piece 52. In order to make efficient use of the space inside the housing 1, one end of the second contact column 51 extends out of the housing 1, and the other end thereof extends into the enclosed space. The conductive pole piece 52 includes a connection section and a contact section. The connecting section is provided with a connecting hole, and is sleeved at one end of the second contact column 51 extending into the closed space through the connecting hole and is electrically connected with the second contact column 51. The contact section is bent perpendicularly with respect to the connection section, so that the conductive pole piece 52 has an L-shaped structure. The contact section extends into the mounting groove 13 and is fixed on one side of the mounting plate 11 facing the through hole 12. Preferably, the conductive pole piece 52 is attached to one side of the mounting plate 11 facing the through hole 12. Therefore, the conductive pole piece 52 forms a flat contact sheet for the contact of the conductive elastic sheet 22, and the contact area is increased. In practical applications, the conductive tab may be adhered to the mounting plate 11 by an adhesive, or the conductive tab 52 may be fastened to the mounting plate 11 by a fixture block or a screw.

Further, one end of the contact section, which is far away from the connection section, is bent in a U shape or in a Z shape, and the bent end in the U shape or the bent end in the Z shape is attached to one side, facing the through hole 12, of the mounting plate 11, so that the conductive elastic sheet 22 can be contacted with the conductive elastic sheet. The other end extends into the closed space and is attached to one of the mounting plates 11 deviating from the through hole 12. This is favorable to increasing the area of contact section and mounting panel 11 for the contact section is more firm install in mounting panel 11 prevents that contact section and mounting panel 11 from producing relative displacement.

One end of the conductive elastic sheet 22 is fastened to the mounting plate 11, and the other end of the conductive elastic sheet extends into the mounting groove 13, is located between the conductive pole piece 52 and the key assembly 3, and can swing between the conductive pole piece 52 and the key assembly 3. Specifically, the conductive dome 22 includes a fixed segment 221 and a cantilever segment 222. The fixed section 221 has one end fastened to the mounting plate 11 and the other end connected to the cantilever section 222. In practical applications, the conductive tab may be adhered to the mounting plate 11 by an adhesive, or the conductive tab 52 may be fastened to the mounting plate 11 by a fixture block or a screw.

Preferably, as shown in fig. 4, the mounting plate 11 is provided with at least one first rib 111 protruding towards the through hole 12, and the first ribs 111 are arranged at intervals and have the same height protruding relative to the mounting plate 11. The fixing segment 221 is erected on each first rib 111, and is attached to the surface of each first rib 111, thereby forming a height difference with the surface of the mounting plate 11. The height difference is beneficial to increasing the swing stroke of the conductive elastic sheet 22, and the contact problem caused by insufficient stroke or elasticity of the conductive elastic sheet 22 is avoided. Further, a clamping plate 14 parallel to and spaced apart from the mounting plate 11 is disposed in the mounting groove 13, and the fixing section 221 is clamped by a gap between the clamping plate 14 and the at least one first rib 111. Of course, at least one second rib 141 may be provided on the engaging plate 14, and the at least one second rib 141 and each first rib 111 are disposed in a staggered manner, so as to increase the engaging area of the fixing section 221. Further, one end of the fixing section 221, which is far away from the cantilever section 222, is a U-shaped bent portion 2211, and the U-shaped bent portion 2211 is wrapped on two sides of the mounting plate 11 to increase the fastening force.

As shown in fig. 5, the cantilever segment 222 is a fold line structure, and includes a first fold 2221 connected to the fixed segment 221, a second fold 2222 connected to the first fold 2221, and a third fold 2223 connected to the second fold 2222. When key assembly 3 moves to the first position, key assembly 3 is to first hem 2221 pressure for first hem 2221 takes place elastic deformation, and drives second hem 2222 and third hem 2223 orientation the mounting panel 11 swings, and third hem 2223 with contact segment elastic butt, thereby make pneumatic switch body 21's second wire is connected with second contact 5 electricity to switch on pneumatic switch body 21's supply circuit. At this time, the user only needs to inhale air and generate negative pressure near the pneumatic switch body 21, so that the pneumatic switch body 21 can be triggered and the power supply device is controlled to output power. When the key assembly 3 moves from the first position to the second position, the pressure applied by the mounting member assembly to the first folding edge 2221 is gradually released, the first folding edge 2221 gradually recovers elastic deformation and is far away from the mounting plate 11 until the mounting plate 11 recovers to the initial position, the second folding edge 2222 and the third folding edge 2223 are also far away from the mounting plate 11, and the third folding edge 2223 is completely separated from the contact section, so that the second wire is disconnected from the second contact member to disconnect the power supply circuit of the pneumatic switch. At this time, the user inhales in time and generates a negative pressure near the pneumatic switch body 21, and the pneumatic switch cannot be triggered, so that the power supply device cannot be prompted to output power. Like this, when the user need not use aerosol generator, can be through moving key assembly 3 to the second position and lock pneumatic switch assembly 2, prevent that children or user from triggering aerosol generator, production safety problem by mistake when not needing to use.

Preferably, the included angle between the first folding edge 2221 and the second folding edge 2222 is an obtuse angle, so that the space occupied by the conductive elastic sheet 22 can be reduced, and the swing formation is increased. The third folding edge 2223 is parallel to the portion of the conductive sheet 52 attached to the mounting plate 11 (i.e., parallel to the mounting plate 11). This is beneficial for the third folding edge 2223 to form surface contact with the conductive pole piece 52, which greatly increases the stability of electrical contact.

In the present embodiment, as shown in fig. 2-3, the key assembly 3 includes a slider 31 and a key cap 32. The sliding member 31 is a block structure, and a mounting hole is concavely formed on one side of the sliding member facing the key cap 32, a mounting column is convexly formed on the key cap 32, and the mounting column is pressed into the mounting hole and is in interference fit with the mounting hole, so that the key cap 32 is fastened on the sliding member 31. The through hole 12 arranged on the shell 1 is in a track shape or a rectangle shape, and the shape of the keycap 32 is matched with that of the through hole 12. The side of the keycap 32 facing away from the sliding member 31 passes through the through hole 12 and is exposed outside the housing 1 for operation by a user. Preferably, the surface of one side of the keycap 32 exposed outside the shell is a rough surface. It can form the rough surface through setting up decorative pattern, slot, hobbing cutter or bump to the user operation, prevent to skid. The size of the key cap 32 in the sliding direction thereof is smaller than that of the through hole 12, thus reserving the sliding stroke of the key cap 32 in the sliding direction. When the part of the keycap 32 exposed outside the housing 1 is subjected to an external force, the keycap 32 can move in the through hole 12 and drive the sliding member 31 to slide in the housing 1. Preferably, the length of the racetrack or rectangular through hole 12 may be used to limit the position of the key assembly 3. When the key cap 32 moves to abut against one end of the through hole 12 and cannot move continuously, the key assembly 3 is in the first position; when the key cap 32 is moved to abut against the other end of the through hole 12 and cannot move, the key assembly 3 is in the second position.

The other side of the sliding member 31, which is away from the key cap 32, is provided with a protruding block 311 in a protruding manner. The surface of the projection 311 facing away from the slider 31 is parallel to the mounting plate 11 and the contact section. When the sliding member 31 moves, the surface of the first folding edge 2221 moves, and an included angle is formed between the plane of the first folding edge 2221 and the plane of the surface of the protrusion 311. Therefore, the sliding member 31 also applies pressure to the first folding edge 2221 during the moving process, so that the first folding edge 2221 drives the second folding edge 2222 and the third folding edge 2223 to move toward the mounting plate 11 until the third folding edge 2223 is attached to the contact section. Conversely, when the protrusion 311 is driven by the key cap 32 to move in the opposite direction, the first folding edge 2221 rebounds and drives the third folding edge 2223 to separate from the contact segment. Preferably, the protrusion 311 is located right above the first folding edge 2221, and a center line of the protrusion 311 coincides with a center line of the first folding edge 2221. Further, the length of the protrusion 311 is equal to or greater than the width of the first folding edge 2221, so as to maximize the contact area between the two, increase the smoothness of pressing, and prevent the first folding edge 2221 from deflecting due to uneven stress.

Further, a sliding slot 15 adapted to the sliding member 31 is disposed in the housing 1, and at least a portion of the sliding member 31 is accommodated in the sliding slot 15 and can slide along the sliding slot 15. The sliding direction of the sliding member 31 is guided by the engagement between the sliding member 31 and the slide groove 15, and the sliding member 31 is prevented from being displaced during the sliding.

Further, as shown in fig. 4, a pair of elastic protrusions, which are respectively referred to as a first elastic protrusion 151 and a second elastic protrusion 152, are protruded from the inner wall of the sliding slot 15. The line connecting the first elastic protrusion 151 and the second elastic protrusion 152 is parallel to the extending direction of the slide slot 15. The two elastic projections may be located on the same side wall of the slide slot 15, or both on the bottom wall of the slide slot 15. Preferably, the first elastic protrusion 151 is located at one end of the bottom wall of the sliding slot 15, and the second elastic protrusion 152 is located at the other end of the bottom wall of the sliding slot 15. Correspondingly, the sliding member 31 is provided with a pair of grooves, which are respectively referred to as a first groove and a second groove. Wherein, the first elastic protrusion 151 is adapted to the first groove, and the second elastic protrusion 152 is adapted to the second groove. When the sliding member 31 is driven by the keycap 32 to move to the position where the first elastic protrusion 151 is clamped into the first groove, the sliding member 31 moves to the first position, and the sliding member 31 is restricted by the cooperation between the first elastic protrusion 151 and the first groove to continue sliding, so that the limiting effect is achieved. When the sliding member 31 is driven by the key cap 32 to slide in the opposite direction, the first elastic protrusion 151 is disengaged from the first groove, and the sliding member 31 continues to slide until the second elastic protrusion 152 is engaged with the second groove, and the sliding member 31 moves to the second position. The slider 31 is held in the second position by the engagement between the second elastic projection 152 and the second groove. Preferably, the first elastic protrusion 151 and the second elastic protrusion 152 are circular protrusions, and the first groove and the second groove are circular grooves. Therefore, the two elastic bulges are in smooth contact with the corresponding grooves respectively, the elastic bulges can be clamped into or slide out of the corresponding grooves conveniently, and the phenomenon that the key assembly 3 slides unsmoothly due to overlarge clamping force of the elastic bulges and the corresponding grooves is avoided.

The present invention further provides an aerosol generator, where the aerosol generator includes any one of the above power supply devices, and the specific structure of the power supply device of the aerosol generator refers to the above embodiments, and since the aerosol generator adopts all technical solutions of all the above embodiments, the aerosol generator at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
