(12) The present disclosure provides an electronic cigarette. The electronic cigarette includes an atomizer, and a battery box 100 connected to the atomizer.

(13) Referring to FIG. 1 and FIG. 2, in an embodiment of the present disclosure, the battery box 100 of the electronic cigarette includes a housing 20, a support 21 partially accommodated in the housing 20, a PCB 22 accommodated in the support 21, and a button assembly 23 connected to the support 21. The button assembly 23 includes a first casing 230, a first magnet 231 connected to the first casing 230, and a second magnet 232 abutting against the first magnet 231. The support 21 defines a limiting hole 210 configured for accommodating the second magnet 232. The second magnet 232 is connected to the PCB 22. The first casing 230 is matched with and connected to the housing 20.

(14) Specifically, the battery box 100 is internally provided with a battery (not shown in the drawings) configured for supplying power to the PCB 22. The support 21 is fabricated by an aluminum alloy/zinc alloy plating process to realize electrical communication between the PCB 22 and the atomizer. The battery box 100 is configured for supplying electrical power to the atomizer (not shown in the drawings). The PCB 22 has two ends connected to the support 21 respectively. In order to make the PCB more stabilized, the support 21 can define a clamping groove, so that the PCB 22 is fixed on the support 21 by clamping, or, the PCB 22 can be stably connected to the support 21 through a bolt. The support 21 defines a limiting hole 210. The limiting hole 210 directly faces the first magnet 231. The second magnet 232 is accommodated in the limiting hole 210 and is in tight connection with the first magnet 231. The first magnet 231 and the second magnet 232 have opposite poles on the two surfaces where they are connected, so as to realize tight connection. The other surface of the second magnet 232 is connected to the PCB 22. The PCB 22 is provided with a contact terminal 220 (that is, start switch). The second magnet 232 abuts against the contact terminal 220. The working principle of the battery box 100 is as follows. When the first casing 230 is pressed by an external force, the second magnet 232 triggers the contact terminal 220 on the PCB 22 to start ignition, under the action of the external force; when the first casing 230 is released, the second magnet 232 shuts down ignition under the resilience force of the contact terminal 220.

(15) The battery box 100 of the electronic cigarette of the present disclosure employs the principle that magnets attract each other. The first magnet 231 is arranged inside the first casing 230. The first casing 230 is in tight connection with the support 21 through the second magnet 232 on the support 21. The battery box 100 is simple in overall structure. The limiting hole 210 can facilitate accurate alignment when the first casing 230 is pressed to trigger the switch on the PCB 22. The size of the battery box is reduced and the electric cigarette is convenient to carry.

(16) Referring to FIG. 2, in order to prevent the first magnet 231 swinging randomly inside the first casing 230 and to prolong the service life of the button, the first casing 230 defines a first groove 2300, and the first magnet 231 is accommodated in the first groove 2300.

(17) Further, in order to enable the first casing 230 to tightly fit the support 21, the button assembly 23 further includes a third magnet 234 connected to the first casing 230, and the support 21 is provided with a connector 211 configured for accommodating the third magnet 231. In order to enable the third magnet 231 to be in firmer connection with the first casing 230, the first casing 230 defines a second groove 2301, and the third magnet 231 and the connector 211 are both accommodated in the second groove 2301.

(18) Further, the button assembly 23 includes a limiting element 233 configured for accommodating the second magnet 232, the limiting element 233 is accommodated in the limiting hole 210 and abuts against the first magnet 231. The second magnet 232 is accommodated in the limiting element 233 so as to facilitate ease of connecting the second magnet 232 to the support 21. Moreover, the limiting element 233 abuts against the first magnet 231, enhancing the stability of the connection of the first magnet 231 and the second magnet 232.

(19) Further, referring to FIG. 3 and FIG. 4, in order to prevent stuck key and improve hand feeling, the battery box 100 further includes an elastic element 24, and the elastic element 24 has two ends connected to the second magnet 232 and the contact terminal 220 respectively. The elastic element 24 is a silicone element. When the first casing 230 is pressed, the second magnet 232 presses against the elastic element 24, the elastic element 24 deforms and triggers the contact terminal 220 on the PCB 22 to start ignition. When the first casing 230 is released, the second magnet 232 disengages from the contact terminal 220 to shut down ignition, under the action of the resilience force of the elastic element 24 and the contact terminal 220.

(20) Further, in order to detach and assemble the battery box 100 conveniently, the housing 20 is provided with a plurality of locating columns 200, the support 21 defines a plurality of first through holes 213, and each locating column 200 is connected to each first through hole 213 via a connecting rod 25.

(21) Further, in order to detach and assemble the battery box 100 from and on the atomizer conveniently, the support 21 defines a second through hole 212, the atomizer is provided with a connection end, and the connection end is accommodated in the second through hole 212.

(22) The battery box of the electronic cigarette of the present disclosure employs the principle that magnets attract each other. The second magnet not only can control the start switch on the PCB as a main button, but also can attract the first casing so as to be in tight connection with the first casing. The overall structure is detachable. Since the structure of the battery box is simple and the size of the battery box can be greatly reduced, the electronic cigarette has a smaller size and is more convenient to carry. Grooves and holes are designed inside the button to prevent left-right swinging of the button, thereby prolonging the service life of the button. The elastic element is arranged between the contact terminal and the second magnet and thus enhances the hand feeling of the button.

(23) The above are preferred embodiments of the present disclosure merely and are not intended to limit the patent scope of the present disclosure. Any equivalent structures made according to the description and the accompanying drawings of the present disclosure without departing from the idea of the present disclosure, or any equivalent structures applied in other relevant technical fields directly or indirectly are intended to be included in the patent protection scope of the present disclosure.
