The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The invention provides a power supply device of an aerosol generator, and please refer to fig. 1-10, the power supply device comprises a shell 1, a pneumatic switch 2 arranged in the shell 1, a first contact element 3, a second contact element 4 and a key assembly 5, wherein one end of the first contact element 3 and one end of the second contact element 4 are both accommodated in the shell 1, the other ends of the first contact element 3 and the second contact element 4 extend out of the shell 1 to be electrically contacted by an external load, one end of the first contact element 3 accommodated in the shell 1 is electrically connected with one end of the pneumatic switch 2, the key assembly 5 is slidably arranged in the shell 1 and is electrically connected with the other end of the pneumatic switch 2, and when the key assembly 5 slides to a first position relative to the shell 1, the key assembly 5 is electrically connected with the second contact element 4; when key assembly 5 is slid to a second position relative to housing 1, key assembly 5 is separated from second contact 4 to disconnect. The locking and unlocking of the pneumatic switch 2 are realized through the sliding key assembly 5, the pneumatic switch 2 is prevented from being triggered by mistake, and therefore the use safety of the aerosol generator is improved.

Referring to fig. 2-4, a cavity is formed in the housing 1, a mounting plate 11 is disposed in the cavity, and the mounting plate 11 divides the cavity into two placing spaces (not shown). The pneumatic switch 2 is arranged in the first placing space, and the key assembly 5 is slidably arranged in the second placing space and partially extends out of the shell 1. The pneumatic switch 2 in this embodiment is an integrated pneumatic switch 2 integrated with a control circuit, so that a control circuit board does not need to be arranged in the housing 1, the space in the housing 1 is saved, and the aerosol generator is convenient to miniaturize, thereby facilitating the carrying of a user and reducing the production cost. Correspondingly, a mounting seat is arranged in the shell 1, and the pneumatic switch 2 is fixed on the mounting seat. The pneumatic switch 2 comprises a pneumatic switch body, wherein a first lead is led out of one end of the pneumatic switch body, and a second lead is led out of the other end of the pneumatic switch body. The first wire is electrically connected to the first contact 3, and the second wire is electrically connected to the key assembly 5.

In practical applications, the first contact member 3 may be a first contact column with elasticity, the first contact column penetrates through the housing 1, one end of the first contact column is exposed outside the housing 1 for electrical contact of an external load, and the other end of the first contact column extends into the first placing space and is electrically connected with the pneumatic switch body by a welding wire. The second contact 4 comprises a second contact post 41 and a pole piece 42. One end of the contact column extends out of the shell 1, and the other end of the contact column is accommodated in the first accommodating space. One end of the pole piece is sleeved on one end of the second contact column 41 extending into the casing 1, and the other end of the pole piece is vertically bent relative to the second contact column 41 and fastened to one side of the mounting plate 11 facing the key assembly 5 so as to electrically contact the key assembly 5. Because the first contact member 3 and the second contact member 4 are electrically connected to the battery element, respectively, when the key assembly 5 moves to be electrically connected to the second contact member 4, both ends of the switch body of the pneumatic switch 2 are electrically connected to the battery element, respectively, so that the power-on is completed, that is, the locking is released. At this time, the user can trigger the pneumatic switch body only by inhaling. When the key assembly 5 moves to be separated from the contact with the second contact member 4, the trigger circuit of the pneumatic switch body is disconnected, and at the moment, a user inhales air, and negative pressure generated near the pneumatic switch body cannot trigger the pneumatic switch body due to other external factors. Therefore, when the pneumatic switch 2 is locked, the electronic cigarette can be effectively prevented from being sucked by children by mistake or being triggered by mistake.

As shown in fig. 5 and 7, the key assembly 5 includes a sliding member 51 and a third contact member 52, the sliding member 51 is slidably connected to the housing 1, and the third contact member 52 is fastened to the sliding member 51. When the sliding member 51 slides relative to the housing 1 under an external force, the sliding member 51 drives the third contact member 52 to move. When the sliding member 51 moves to the first position, the third contact member 52 is electrically connected to the second contact member 4, so that the second lead of the pneumatic switch body is electrically connected to the battery element through the third contact member 52, and the circuit is conducted, thereby completing unlocking of the pneumatic switch 2. At this time, the user can trigger the pneumatic switch 2 to press by inhaling, and the electronic cigarette is normally smoked. When the sliding member 51 moves to the second position, the third contact member 52 is out of contact with the second contact member 4, so that the circuit is broken, and the pneumatic switch 2 is locked. At the moment, the user can not trigger the pneumatic switch 2 by inhaling, so that false triggering is prevented, and the use safety of the electronic cigarette is improved.

In one embodiment of the present invention, referring to fig. 6, the sliding member 51 includes a sliding block 511 and a key cap 512. The slider 511 may have a regular or irregular block structure. In this embodiment, the slider 511 is a regular block structure including six end surfaces. The key cap 512 is fixedly connected with the sliding block 511. Specifically, a mounting hole is concavely formed in a first end surface of the sliding block 511 facing the keycap 512, a mounting column is convexly formed on the keycap 512, and the mounting column is pressed into the mounting hole and is in interference fit with the mounting hole, so that the keycap 512 is fastened to the sliding block 511. The shell 1 is provided with a track-shaped or rectangular through hole 12, and one side of the keycap 512, which is far away from the sliding block 511, is accommodated in the through hole 12 and is exposed out of the shell 1 for operation by a user. The size of the keycap 512 in the sliding direction is smaller than that of the through hole 12, so that the sliding stroke of the keycap 512 in the sliding direction is reserved. When the part of the keycap 512 exposed outside the housing 1 is subjected to an external force, the keycap 512 can move in the through hole 12 and drive the slider 511 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 5. When the key cap 512 moves to abut against one end of the through hole 12 and cannot move continuously, the key assembly 5 is at a first position; when the key cap 512 moves to abut against the other end of the through hole 12 and cannot move, the key assembly 5 is in the second position.

The outer surface of at least one end of the slider 511 is provided with a sliding portion 5111. Correspondingly, a sliding groove 13 matched with the sliding part 5111 is arranged in the housing 1, and at least part of the sliding part 5111 is accommodated in the sliding groove 13 and can slide along the sliding groove 13. The sliding direction of the slider 511 is guided by the engagement between the sliding portion 5111 and the sliding groove 13, and the slider 511 is prevented from being displaced during the sliding. In practical applications, the sliding portion 5111 may be provided at one end of the slider 511, or the sliding portions 5111 may be provided at two or more ends thereof. Preferably, the opposite ends of the slider 511 are provided with sliding portions 5111, that is, the second end surface and the third end surface perpendicularly connected to the first end surface are provided with sliding portions 5111. The shell 1 is correspondingly provided with a matched sliding groove 13. Thus, the opposite ends of the sliding block 511 can be guided by the sliding grooves 13, and the sliding block 511 can slide smoothly.

Further, as shown in fig. 4, a pair of elastic protrusions, which are respectively referred to as a first elastic protrusion 131 and a second elastic protrusion 132, are protruded from the inner wall of the sliding slot 13. The line connecting the first elastic protrusion 131 and the second elastic protrusion 132 is parallel to the extending direction of the sliding chute 13. The two elastic projections may be located on the same side wall of the sliding slot 13, or both may be located on the bottom wall of the sliding slot 13. Preferably, the first elastic protrusion 131 is located at one end of the bottom wall of the sliding chute 13, and the second elastic protrusion 132 is located at the other end of the bottom wall of the sliding chute 13. Correspondingly, the sliding portion 5111 is provided with a pair of grooves, which are respectively referred to as a first groove 5112 and a second groove 5113. Wherein, the first elastic protrusion 131 is matched with the first groove 5112, and the second elastic protrusion 132 is matched with the second groove 5113. When the sliding block 511 is driven by the keycap 512 to move to the position where the first elastic protrusion 131 is clamped in the first groove 5112, the sliding block 511 moves to the first position, and the sliding block 511 is restricted by the cooperation between the first elastic protrusion 131 and the first groove 5112 to continue to slide, so that the limiting effect is achieved. When the sliding block 511 slides in the opposite direction under the driving of the keycap 512, the first elastic protrusion 131 is disengaged from the first groove 5112, and the sliding block 511 continues to slide until the second elastic protrusion 132 is engaged with the second groove 5113, and the sliding block 511 moves to the second position. The slider 511 is maintained at the second position by the engagement between the second elastic projection 132 and the second groove 5113. Preferably, the first elastic projection 131 and the second elastic projection 132 are circular projections, and the first groove 5112 and the second groove 5113 are circular grooves. Therefore, the two elastic bulges are in smooth contact with the corresponding grooves respectively, the elastic bulges are clamped into or slide out of the corresponding grooves, and the phenomenon that the key assembly 5 slides unsmoothly due to overlarge clamping force of the elastic bulges and the corresponding grooves is avoided.

In the present embodiment, as shown in fig. 5, the third contact member 52 has a T-shaped sheet structure including a contact section 521, a first connection section 523, and a second connection section 522. The first connecting section 523 is vertically connected to one end of the contact section 521, and the second connecting section 522 is vertically connected to the other end of the contact section 521. The first connecting section 523 is provided with a first connecting hole, and the fourth end surface of the slider is provided with a second connecting hole 5116 which is concentric. And the fourth end surface is respectively and vertically connected with the first end surface, the second end surface and the third end surface. The first connection segment 523 is fastened to the slider 51 by a connection member 6 sequentially passing through the first and second connection holes 5116. A fifth end surface of the slider 511 opposite to the first end surface is provided with a mounting groove 5114.

Preferably, the power supply device further comprises a fourth contact member 8, and the fourth contact member 8 may be a conductive pole piece having ductility and elasticity. One end of the fourth contact member 8 is fastened to the mounting plate 11 and electrically connected to the second wire of the pneumatic switch 2, and the other end is provided with a first elastic convex hull 81 facing the contact section 521, and the first elastic convex hull 81 elastically abuts against the contact section 521, so that the third contact member 52 is electrically connected to the pneumatic switch body. This embodiment makes through first elasticity convex closure 81 and second elasticity convex closure 421 casing 1 with form elastic contact between the key assembly 5, increased the atress of key assembly in the vertical sliding direction, be favorable to the restriction the displacement of key assembly 5 strengthens the feeling of user operation button.

Further, the portion of the mounting plate 11 facing the contact section 521 is provided with an accommodating groove 111, the accommodating groove 111 is filled with a buffer 7, and the buffer 7 may be made of elastic silica gel, rubber or silicon rubber. First elasticity convex hull 81 and second elasticity convex hull 421 all extend to bolster 7 to when first elasticity convex hull 81 and second elasticity convex hull 421 play by pressed and take place elastic deformation, bolster 7 can produce deformation and absorb partial pressure, can increase elasticity on the one hand, and on the other hand can avoid second elasticity arch 132 and second elasticity arch 132 to be squashed in the use, reaches the effect of the two life of extension.

In another embodiment of the present invention, referring to fig. 7 and 8, the sliding member 51 includes an upper cover 513 and a bottom cover 514. The bottom cover 514 is provided with a first slot 5141 facing the keycap 512, the upper cover 513 is provided with a second slot 5131 facing the bottom cover 514, and the bottom cover 514 is clamped with the upper cover 513, so that the first slot 5141 and the second slot 5131 form a receiving groove 515 for mounting the third contact element 52. A force part 5132 is convexly arranged on one side of the upper cover 513, which is away from the bottom cover 514, and the force part 5132 is received through the through hole 12 and exposed outside the housing 1 for operation by a user. The third contact 52 includes a contact cap 524, a terminal plate 525, and a resilient member 526. The contact cap 524 has one end received in the receiving groove 515 and connected to the wiring board 525 and the other end passing through the bottom cover 514 and protruding out of the receiving groove 515. An end of the terminal block 525 remote from the contact cap 524 protrudes from the notch of the receiving groove 515 and is electrically connected to a second wire drawn out of the pneumatic switch body. The elastic member 526 is accommodated in the accommodating groove 515, and one end of the elastic member elastically abuts against the contact cap 524, and the other end of the elastic member elastically abuts against the upper cover 513. Further, the contact cap 524 is provided with a first guide groove, and the upper cover 513 is provided with a second guide groove 5133. Both ends of the elastic member 526 are caught in the first and second guide grooves 5133, respectively. The two guide grooves limit the extension direction of the elastic member 526, so as to prevent the elastic member 526 from deviating, and the contact cap 524 is prevented from shaking to cause poor contact.

As shown in fig. 9 and 10, the mounting plate 11 is convexly provided with an arc-shaped step 111 towards the contact cap 524, and the edge of the arc-shaped step 111 smoothly transitions with the housing 1 so as to facilitate smooth movement during sliding of the contact cap 524. In practical applications, the curvature and gradient of the curved step 111 may be determined according to the elasticity of the elastic member or the sliding feeling desired by the user. When the force applying portion 5132 is subjected to an external force, the upper cover 513 drives the contact cap 524 to move until the contact cap 524 crosses the arc-shaped step 111 and is located on the same side of the arc-shaped step 111 as the second contact 4, the slider 51 is in the first position, and the contact cap 524 elastically abuts against the second contact 4 to form an electrical connection. In the process, the elastic member 526 is gradually compressed in the process of approaching the arc-shaped step 111, and the compression amount is maximum when the elastic member crosses the highest point of the arc-shaped step 111; and gradually rebounds in the process of moving away from the arc-shaped step 111 and approaching the second contact element 4 again, and pushes the contact cap 524 to abut against the second contact element 4, so that the contact cap 524 is ensured to be stably contacted with the second contact element 4. Similarly, when the key cap 512 moves reversely by an external force, the upper cover 513 drives the contact cap 524 to move, so that the contact cap 524 is separated from the second contact element 4 until the contact cap 524 passes over the arc-shaped step 111 and is located on two sides of the arc-shaped step 111 with the second contact element 4, and at this time, the sliding element 51 is located at the second position.
