(15) The invention provides a battery assembly 100, which is applied to an electronic cigarette. The electronic cigarette comprises an atomizer (not shown). An oil storing chamber and a heat generating assembly are provided in the atomizer. The battery assembly 100 is provided with a connecting assembly which is fixedly electrically connected with the atomizer, and the circuit board 30 provided in the battery assembly 100 controls the output current of the power supply to supply power to the heat generating assembly in the atomizer, so that the heat generating assembly heats tobacco tar when driven by the battery assembly 100 to generate smoke, thus giving the user a smoking experience. The battery assembly 100 is provided with a rechargeable battery element 70 therein, and is provided with a plug-in terminal 31 for charging and data transmission. The plug-in terminal 31 may use a micro jack, a lighting jack or a type c jack.

(16) Referring to FIG. 1 to FIG. 7, in the embodiment of the invention, the battery assembly 100 comprises a main body 10, a circuit board 30 mounted in the main body 10 and a button assembly 50, wherein the main body 10 is provided with an avoidance hole 112 and at least one stopper 1213, the button assembly 50 comprises a button cap 51 and a button contact 52, the button contact 52 is fixedly mounted in the main body 10 and is electrically connected with the circuit board 30, and the button cap 51 is slidably mounted in the avoidance hole 112 and abuts against the stopper 1213 when the button cap slides to squeeze the button contact 52 to form a trigger position and trigger the button contact 52 to transmit a control signal to the circuit board 30.

(17) For the battery assembly 100 of the technical solution of the invention, the main body 10 is provided with an avoidance hole 112 and at least one stopper 1213. When the user presses the button cap 51, the button cap 51 is driven to abut against the stopper 1213 when the button cap 51 slides along the avoidance hole 112 to squeeze the button contact 52. When the user further presses the button cap with an excessive force, the stopper 1213 has a limiting supporting force on the button cap 51, limiting the button cap 51 to further squeeze the button contact 52, preventing the phenomenon that the deformation of the button contact 52 under the action of a large pressing force during long-term use results in a decreased trigger sensitivity, effectively improving the service life of the button assembly 50, and preventing the phenomenon that a large pressing force crushes the circuit board 30.

(18) Further, as shown in FIG. 1 to FIG. 3, in the embodiment of the invention, an elastic member 53 is further provided between the button cap 51 and the button contact 52, one of the button cap 51 and the button contact 52 is fixedly connected with the elastic member 53, and the other thereof elastically abuts against the elastic member 53. Here, in the embodiment, one end of the elastic member 53 is fixed to the button cap 51, and the other end elastically abuts against the button contact, thereby effectively improving the resilience generated when the button cap 51 is released after being pressed, so that the button cap 51 slides toward the outside of the main body 10 along the avoidance hole 112 under the elastic restoring force of the elastic member 53 when not pressed, and is partially exposed to the outside of the main body 10 for the user to press.

(19) It is to be understood that, in the actual application process, the manner in which the elastic member 53 may use a spring 124, an elastic silicone rubber or elastic plastic to improve the resilience generated when the button cap 51 is released after being pressed falls within the scope of protection of the invention. Similarly, the mounting manner in which one end of the elastic member 53 may also be fixedly connected with the elastic contact, and the other end elastically abuts against the button cap 51 falls within the scope of protection of the invention.

(20) Further, as shown in FIG. 1 to FIG. 4, in the embodiment of the invention, one of the button cap 51 and the elastic member 53 is convexly provided with a fixed column 511, and the other thereof is provided with a groove 531, the fixed column 511 is inserted into the groove 531, and the elastic member 53 is fixed to the button cap 51. Here, in the embodiment, the elastic member 53 is made of elastic silicone. One end of the button end 51 toward the button contact 52 is convexly provided with a fixed column 511, and then a groove 531 is provided in the elastic silicone. The area surrounded by the periphery of the groove 531 is slightly smaller than the surface area surrounded by the outer periphery of the fixed column 511. When the fixed column 511 is inserted into the groove 531, the inner wall of the groove 531 is squeezed to be fixed in an interference fit. At the same time, the extruded elastic silicone has a retractable elastic deformation force, so that it is closely sleeved to the fixed column 511, effectively preventing the phenomenon that the elastic member 53 is disengaged from the button cap 51 during the long-term use of the button assembly 50.

(21) Further, as shown in FIG. 1 to FIG. 4, in the embodiment of the invention, the button cap 51 is further convexly provided with at least one limiting member 512, and each of the limiting members 512 abuts against a portion of the outer periphery of the elastic member 53 when the elastic member 53 is fixedly mounted to the button cap 51. Here, in the present embodiment, the button cap 51 is convexly provided with an annular limiting member 512. When the elastic member 53 is sleeved to the fixed column 511, the elastic limiting member 512 is sleeved to the outer periphery of the end of the elastic member 53 provided with a groove 531, and the elastic member 53 is partially buckled between the limiting member 512 and the fixed column 511, thereby further preventing the phenomenon that the elastic member 53 is disengaged from the button cap 51 during the long-term use of the button assembly 50.

(22) It is to be understood that, in the actual application process, the button cap 51 is not limited to preventing the phenomenon that the elastic member 53 is disengaged from the button cap 51 in such a manner that the annular limiting member 512 is convexly provided. For example, the button cap 51 may be also convexly provided with a plurality of limiting blocks. The manner in which the limiting blocks are provided at intervals around the fixed column 511 to partially buckle the elastic member 53 between the limiting member 512 and the fixed column 511 to prevent the elastic member 53 from being disengaged from the button cap 51 falls within the scope of protection of the invention.

(23) Specifically, as shown in FIG. 4, in the embodiment of the invention, one end of the annular limiting block far away from the button cap 51 is further convexly provided with two auxiliary bumps 5121 which abuts against the outer periphery of the elastic member 53, effectively increasing the clamping area with the elastic member 53, and further preventing the phenomenon that the elastic member 53 is disengaged from the button cap 51 during the long-term use of the button assembly 50.

(24) Further, as shown in FIG. 1 or FIG. 2, in the embodiment of the invention, the elastic member 53 is further provided with an extending part 532 which elastically abuts against the side structure of the circuit board 30 when the button cap 51 slides to the trigger position. Here, in the present embodiment, the elastic member 53 is further provided with an extending part 532. When the button cap 51 slides to the trigger position, that is, in the process that the button cap 51 slides to squeeze the elastic contact, the extending part 532 is first in contact with the side structure of the circuit board 30, and as the button cap 51 continues to slide, the extending part 532 elastically squeezes the circuit board 30. The elastic resisting force is continuously increased, further preventing the phenomenon that when the pressing force of the user is excessive, the button contact 52 is deformed, resulting in a decrease in sensitivity.

(25) Further, as shown in FIG. 1 or FIG. 2, in the embodiment of the invention, one of the extending part 532 and the button cap 51 is provided with a connecting buckle 5321, and the other thereof is provided with a connecting groove 514, and the connecting buckle 5321 is inserted into the connecting groove 514 to fix the extending part 532 to the button cap 51. Here, in the present embodiment, one end of the extending part 532 far away from the groove 531 is convexly provided with a connecting buckle 5321, the button cap 51 is provided with a connecting groove 514, the connecting buckle 5321 is fastened to the connecting groove 514, and one end of the extending part 532 far away from the groove 531 is fixed to the button cap 51, thereby effectively preventing the phenomenon that the elastic member 53 is disengaged from the button cap 51 due to the misalignment of the extending part 532 during the long-term use.

(26) It is to be understood that, in the actual application process, the extending part 532 and the button cap 51 are not limited to the manner in which a connecting buckle 5321 and a connecting groove 514 are provided to be fastened and connected. For example, the manner in which a fastener such as a screw is fixed, a plurality of buckles and necks are fastened, or one end of the extending part 532 far away from the groove 531 extends away from the button cap 51 to abut against the circuit board 30, and the extending part 532 abuts against the outer surface of the button cap 51 may also be used. All the manners fall within the scope of protection of the invention.

(27) Further, as shown in FIG. 5, in the embodiment of the invention, the end of the button cap 51 toward the button contact 52 is further provided with a flange 513, which abuts when being in contact with the periphery of the avoidance hole 112 to limit the button cap 51 to the main body 10. Here, in the embodiment, the end of the button cap 51 toward the button contact 52 is further provided with a flange 513. The button cap 51 slides along the avoidance hole 112 from the outside of the main body 10 to the flange 513 under the elastic restoring force of the elastic member 53 to abut against the periphery of the avoidance hole 112, thereby effectively preventing the phenomenon that the button cap 51 is disengaged from the main body 10.

(28) Specifically, as shown in FIG. 3, in the embodiment of the invention, the main body 10 comprises a sleeve 11, a connecting assembly 12 and an end cover 13, the sleeve 11 is provided with a battery chamber 111 for receiving the battery 70, the end cover 13 and the connecting assembly 12 are fixedly mounted on both ends of the sleeve 11, respectively, and block the battery chamber 111, the connecting assembly 12 is fixedly connected with the circuit board 30 and is used to connect an external load and conduct the external load and the circuit board 30, and the avoidance hole 112 is provided on the outer periphery of the sleeve 11.

The end cover 13 is fixedly connected with the sleeve 11 by a thread and blocks the battery chamber 111. The connecting assembly 12 is fixedly mounted on an end of the sleeve 11 far away from the end cover 13. The circuit board 30 is mounted in the sleeve 11 and is fixedly connected with the connecting assembly 12 by a screw, thereby effectively preventing the circuit board 30 from shaking, and facilitating the wiring of the circuit board 30 and the connecting assembly 12, effectively saving mounting space and reducing product volume.

(29) Further, as shown in FIG. 3, in the embodiment of the invention, the sleeve 11 is further provided with at least one light-transmitting decorative member 113 around the avoidance hole 112, the main body 10 is further provided with at least one light source, the light source is electrically connected with the circuit board 30, and the light emitted by the light source is at least partially transmitted from the light-transmitting decorative member 113. Here, in the embodiment, a plurality of LED light sources are integrated on the circuit board 30, the plurality of LED light sources are arranged on both surfaces of the circuit board 30 toward the connecting assembly 12 and far away from the connecting assembly 12, and the light emitted from each of the LED light sources is at least partially transmitted from the light-transmitting decorative member 113, thereby preventing the light from being shielded by the circuit board 30 or other components, resulting in a phenomenon that the light transmitted through the light-transmitting decorative member 113 has different luminosities. When the user presses the button cap 51 to squeeze the button contact 52 to transmit a control signal to the circuit board 30, the control circuit provided by the circuit board 30 controls each of the LED light sources to emit light to generate an indication effect, effectively reminding the user of the operating state of the battery assembly 100.

(30) It is to be understood that, in the actual application process, the manner in which those skilled in the art may also adjust the illumination intensity, strobe flash and color conversion of the LED lamp bead by adding a PWM circuit module (not shown) on the circuit board 30 to realize various lighting effects falls within the scope of protection of the invention.

(31) Specifically, as shown in FIG. 1, in the embodiment of the invention, both ends of the battery 70 are further provided with a covering member 60. In the embodiment, the covering member 60 is made of foam, effectively preventing the phenomenon that the hard contact between both ends of the battery 70 results in crushing short circuit.
