Description

Technical Field

[0001] The invention relates to a power supply device of an aerosol generator and an aerosol generator using the power supply device of the aerosol generator. Background Art

[0002] The aerosol generator includes an atomizing device that atomizes the e-liquid into an aerosol and a power supply device that provides power to the atomizing device. The power supply device is equipped with a mechanical key switch or a pneumatic switch to trigger the power supply device. When using an aerosol generator equipped with a mechanical switch, the user needs to press the mechanical switch while inhaling to control the atomizing device to atomize the e-liquid; however, when using an aerosol generator equipped with a pneumatic switch, the user only needs to inhale to generate an aerosol. Since the aerosol generator equipped with a pneumatic switch is more convenient and quick to use, it is widely loved by users.

[0003] Existing mechanical key switches or pneumatic switches are all welded to the circuit board, and the key is locked through the circuit on the circuit board. However, due to the miniaturization of the aerosol generator, it is impossible to reserve enough space inside it to configure the circuit board. Many existing small or disposable aerosol generators are only equipped with pneumatic switches. As long as the user draws on the aerosol generator, the pneumatic switch can be triggered, thereby powering the atomization device.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present invention provides a power supply device for an aerosol generator, such as Figure 1-5As shown, it includes a housing 1, a pneumatic switch assembly 2 having a conductive spring 22, a key assembly 3, a first contact 4 and a second contact 5, one end of each of the first contact 4 and the second contact 5 is accommodated in the housing 1, and the other end of each of the first contact 4 and the second contact 5 is extended out of the housing 1 for electrical contact with an external load, the key assembly 3 is slidably mounted on the housing 1, the pneumatic switch assembly 2 is mounted in the housing 1, and the conductive spring 22 is located between the key assembly 3 and the second contact 5. When the key assembly 3 slides to a first position relative to the housing 1, the key assembly 3 applies pressure to the conductive spring 22 so that the conductive spring 22 elastically abuts against the second contact 5. When the key assembly 3 slides to a second position relative to the housing 1, the key assembly 3 removes the pressure, and the conductive spring 22 rebounds to separate from the second contact 5. This embodiment utilizes the elasticity of the conductive spring 22 to separate from or contact the second contact member 5 during the sliding process of the key assembly 3, thereby locking or unlocking the pneumatic switch, preventing the pneumatic switch from being accidentally triggered, and improving the safety of the aerosol generator.

[0033] In this embodiment, please refer to Figure 2-3 The pneumatic switch assembly 2 includes a pneumatic switch body 21 and the conductive spring 22. A first wire (not shown) for electrically connecting to the first contact member 4 is led out from one end of the pneumatic switch body 21, and a second wire is led out from the other end, and the second wire is electrically connected to the conductive spring 22. Preferably, the pneumatic switch body 21 adopts an integrated circuit pneumatic switch. That is, a micro control circuit is integrated in the pneumatic switch body 21, so that there is no need to arrange a control circuit board in the housing 1, thereby saving costs, simplifying the structure in the power supply device, and facilitating the miniaturization of the power supply device.

[0034] like Figure 4 As shown, the shell 1 is a hollow structure with a through hole 12 on one side, and a mounting plate 11 facing the through hole 12 is provided in the shell 1. The mounting plate 11 divides the space in the body into two parts, and the two spaces are respectively located on both sides of the mounting plate 11. The space on one side is a closed space, which is used to install 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 provided in the shell 1. The first contact member 4 includes a first contact column, which passes through the shell 1, one end of which extends into the closed space and is welded to the first wire. The mounting plate 11 forms a mounting groove 13 with the shell 1 on the other side facing the through hole 12, and the button assembly 3 is slidably installed in the mounting groove 13, and partially extends out of the shell 1 from the notch of the mounting groove 13 (i.e., the through hole 12).

[0035] Please refer to Figure 1-3 The second contact member 5 includes a second contact column 51, which is spaced apart from the first contact member 4 and passes through the housing 1, with one end of the second contact column 51 extending into the mounting slot 13 and the other end extending out of the housing 1. Preferably, the end of the second contact column 51 extending into the mounting slot 13 is attached to the mounting plate 11. When the conductive spring 22 elastically abuts against the second contact column 51 under the action of the key assembly 3, the mounting plate 11 can provide support for the second contact column 51 to prevent the second contact column 51 from shaking, thereby causing the problem that the end extending out of the housing 1 has poor contact with the external load.

[0036] In a preferred embodiment of the present invention, Figure 2-3 As shown, the second contact member 5 also includes a conductive electrode sheet 52. In order to effectively utilize the internal space of the shell 1, one end of the second contact column 51 extends out of the shell 1, and the other end extends into the enclosed space. The conductive electrode sheet 52 includes a connecting section and a contact section. The connecting section is provided with a connecting hole, through which it is sleeved on the end of the second contact column 51 extending into the enclosed space and is electrically connected to the second contact column 51. The contact section is vertically bent relative to the connecting section, so that the conductive electrode sheet 52 has an L-shaped structure. The contact section extends into the mounting groove 13 and is fixed to the side of the mounting plate 11 facing the through hole 12. Preferably, the conductive electrode sheet 52 is attached to the side of the mounting plate 11 facing the through hole 12. In this way, the conductive electrode sheet 52 forms a flat contact sheet for the conductive spring sheet 22 to contact, thereby increasing the contactable area. In practical applications, the conductive contact sheet 52 may be adhered to the mounting plate 11 by using adhesive, or the conductive electrode sheet 52 may be fastened to the mounting plate 11 by using a clamp or a screw.

[0037] Furthermore, one end of the contact section away from the connection section is U-shaped or Z-shaped, and one end of the U-shaped or Z-shaped bend is attached to the side of the mounting plate 11 facing the through hole 12 for contact with the conductive spring 22. The other end extends into the closed space and is attached to the side of the mounting plate 11 away from the through hole 12. This is conducive to increasing the contact area between the contact section and the mounting plate 11, so that the contact section is more stably installed on the mounting plate 11, and preventing the contact section and the mounting plate 11 from relative displacement.

[0038] One end of the conductive spring sheet 22 is fastened to the mounting plate 11, and the other end extends into the mounting groove 13, and is located between the conductive electrode sheet 52 and the key assembly 3, and can swing between the conductive electrode sheet 52 and the key assembly 3. Specifically, the conductive spring sheet 22 includes a fixed section 221 and a cantilever section 222. One end of the fixed section 221 is fastened to the mounting plate 11, and the other end is connected to the cantilever section 222. In practical applications, an adhesive can be used to stick the conductive tab to the mounting plate 11, or a clamp block, screw, etc. can be used to fasten the conductive electrode sheet 52 to the mounting plate 11.

[0039] Preferably, Figure 4 As shown, the mounting plate 11 is provided with at least one first rib 111 protruding toward the through hole 12, and each first rib 111 is arranged at intervals and has the same height relative to the mounting plate 11. The fixing section 221 is mounted on each first rib 111 and fits the surface of each first rib 111, thereby forming a height difference with the surface of the mounting plate 11. This height difference is conducive to increasing the swing stroke of the conductive spring 22 and avoiding contact problems caused by insufficient stroke or elasticity of the conductive spring 22. Further, a clamping plate 14 is provided in the mounting groove 13 and is parallel to and spaced from the mounting plate 11. The fixing section 221 is clamped by the gap between the clamping plate 14 and the at least one first rib 111. Of course, at least one second rib 141 can also be provided on the clamping plate 14, and the at least one second rib 141 is staggered with each first rib 111 to increase the clamping area of ​​the fixing section 221. Furthermore, one end of the fixing section 221 away from the cantilever section 222 is in a U-shaped bending portion 2211 , and the U-shaped bending portion 2211 is wrapped around two sides of the mounting plate 11 to increase the fastening force.

[0040] like Figure 5As shown, the cantilever section 222 is a broken line structure, which includes a first folded edge 2221 connected to the fixed section 221, a second folded edge 2222 connected to the first folded edge 2221, and a third folded edge 2223 connected to the second folded edge 2222. When the key assembly 3 moves to the first position, the key assembly 3 applies pressure to the first folded edge 2221, causing the first folded edge 2221 to undergo elastic deformation, and drives the second folded edge 2222 and the third folded edge 2223 to swing toward the mounting plate 11, and the third folded edge 2223 elastically abuts against the contact section, so that the second wire of the pneumatic switch body 21 is electrically connected to the second contact member 5, and the power supply circuit of the pneumatic switch body 21 is turned on. At this time, the user only needs to inhale and generate negative pressure near the pneumatic switch body 21 to trigger the pneumatic switch body 21 and control the power supply device to output power. When the button assembly 3 moves from the first position to the second position, the pressure applied by the mounting assembly to the first folded edge 2221 is gradually withdrawn, the first folded edge 2221 gradually recovers its elastic deformation and moves away from the mounting plate 11 until it returns to its initial position, the second folded edge 2222 and the third folded edge 2223 also move away from the mounting plate 11, and the third folded 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, even if the user inhales in time and generates negative pressure near the pneumatic switch body 21, the pneumatic switch cannot be triggered, and the power supply device cannot be prompted to output power. In this way, when the user does not need to use the aerosol generator, the pneumatic switch assembly 2 can be locked by moving the button assembly 3 to the second position to prevent children or users from accidentally triggering the aerosol generator when it is not needed, causing safety problems.

[0041] Preferably, the angle between the first folded edge 2221 and the second folded edge 2222 is an obtuse angle, which can reduce the space occupied by the conductive spring 22, thereby increasing its swinging shape. The third folded edge 2223 is parallel to the portion of the conductive electrode sheet 52 that is attached to the mounting plate 11 (i.e., parallel to the mounting plate 11). This is conducive to the third folded edge 2223 and the conductive electrode sheet 52 forming a surface contact, which greatly increases the stability of the electrical contact.

[0042] In this embodiment, if Figure 2-3As shown, the key assembly 3 includes a sliding member 31 and a keycap 32. The sliding member 31 is a block-shaped structure, and a mounting hole is recessed on one side of the sliding member 31 facing the keycap 32. The keycap 32 is convexly provided with a mounting column, and the mounting column is pressed into the mounting hole and is interference-fitted with the mounting hole, so that the keycap 32 is fastened to the sliding member 31. The through hole 12 provided on the housing 1 is runway-shaped or rectangular, and the shape of the keycap 32 is adapted to the shape of the through hole 12. The side of the keycap 32 away from the sliding member 31 passes through the through hole 12 and is exposed outside the housing 1 for user operation. Preferably, the surface of one side of the keycap 32 exposed outside the housing is a rough surface. It can be formed into a rough surface by setting a pattern, a groove, a hob or a convex point to facilitate user operation and prevent slipping. The size of the keycap 32 in its sliding direction is smaller than the size of the through hole 12, so that the sliding stroke of the keycap 32 in the sliding direction is reserved. When the portion 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 track-shaped or rectangular through hole 12 can be used to limit the key assembly 3. When the keycap 32 moves to abut against one end of the through hole 12 and cannot move further, the key assembly 3 is in the first position; when the keycap 32 moves to abut against the other end of the through hole 12 and cannot move, the key assembly 3 is in the second position.

[0043] A protrusion 311 is convexly provided on the other side of the sliding member 31 away from the keycap 32. The surface of the protrusion 311 away from the sliding member 31 is parallel to the mounting plate 11 and the contact section. When the sliding member 31 moves, the surface moves along the first folded edge 2221, because the plane where the first folded edge 2221 is located forms an angle with the plane where the surface of the protrusion 311 is located. Therefore, the sliding member 31 also applies pressure to the first folded edge 2221 during the movement, so that the first folded edge 2221 drives the second folded edge 2222 and the third folded edge 2223 to move toward the mounting plate 11 until the third folded edge 2223 is attached to the contact section. On the contrary, when the protrusion 311 moves in the opposite direction driven by the keycap 32, the first folded edge 2221 rebounds and drives the third folded edge 2223 to separate from the contact section. Preferably, the protrusion 311 is located directly above the first folded edge 2221, and the center line of the protrusion 311 coincides with the center line of the first folded edge 2221. Furthermore, the length of the protrusion 311 is equal to or greater than the width of the first folded edge 2221 to maximize the contact area between the two, increase the stability of pressing, and prevent the first folded edge 2221 from being unevenly stressed and thus deflecting.

[0044] Furthermore, a slide groove 15 adapted to the slide member 31 is provided in the housing 1, and the slide member 31 is at least partially accommodated in the slide groove 15 and can slide along the slide groove 15. Through the cooperation between the slide member 31 and the slide groove 15, the sliding direction of the slide member 31 is guided to prevent the slide member 31 from deflecting during the sliding process.

[0045] Further, if Figure 4 As shown, the inner wall of the slide groove 15 is provided with a pair of elastic protrusions, which are respectively recorded as the first elastic protrusion 151 and the second elastic protrusion 152. The connecting line of the first elastic protrusion 151 and the second elastic protrusion 152 is parallel to the extension direction of the slide groove 15. The two elastic protrusions can be located on the same side wall of the slide groove 15, or both are located on the bottom wall of the slide groove 15. Preferably, the first elastic protrusion 151 is located at one end of the bottom wall of the slide groove 15, and the second elastic protrusion 152 is located at the other end of the bottom wall of the slide groove 15. Correspondingly, the sliding member 31 is provided with a pair of grooves, which are respectively recorded as the first groove and the second groove. Among them, 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 moves to the first elastic protrusion 151 and snaps into the first groove under the drive of the key cap 32, the sliding member 31 moves to the first position, and the cooperation between the first elastic protrusion 151 and the first groove limits the sliding member 31 to continue sliding, which plays a role of limiting. When the sliding member 31 slides in the opposite direction under the drive of the key cap 32, the first elastic protrusion 151 escapes from the first groove, and the sliding member 31 continues to slide until the second elastic protrusion 152 snaps into the second groove, and the sliding member 31 moves to the second position. The cooperation between the second elastic protrusion 152 and the second groove keeps the sliding member 31 in the second position. 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. In this way, it is convenient for the two elastic protrusions to form smooth contact with the corresponding grooves, so that the elastic protrusions can be snapped into or slide out of the corresponding grooves, and the elastic protrusions can be prevented from having too large a snapping force with the corresponding grooves, which causes the key assembly 3 to slide unsmoothly.
