[0002] Electronic cigarettes, also known as electronic cigarettes, are mainly composed of an atomizer and a battery that provides power to the atomizer. Its basic working principle is to heat the tobacco oil with the flavor of cigarettes through the atomizer and atomize it into smoke for smokers to use. Because it does not undergo combustion and does not contain tar, suspended particles and other harmful components in cigarettes, it is widely used to replace ordinary cigarettes.

However, the pole ears of this battery are respectively set at both ends of the battery. In order to save electronic space, the battery interface of the electronic cigarette is set at the same end. Therefore, during assembly, it is necessary to weld a wire between the pole ears at both ends of the battery and the battery interface to achieve electrical conduction between the battery and the battery interface. The assembly process is cumbersome, resulting in low assembly efficiency, and because the pole ears and wires are relatively soft and difficult to position, the assembly difficulty is increased; in addition, since the battery and the battery interface are connected by welding, there is also a technical problem of difficulty in replacement and maintenance.

[0061] See also Figures 5 to 7As shown, this embodiment provides a battery module, which is different from the first embodiment only in that the control component 200 includes a second circuit board 220, a discharge connector 230 and a third circuit board 240; the battery 100 is located between the second circuit board 220 and the discharge connector 230, and is electrically connected to the second circuit board 220 through the conductive terminal 140; the third circuit board 240 is located on one side of the battery 100, and the second circuit board 220 is electrically connected to the discharge connector 230 through the third circuit board 240; the second circuit board 220 is also provided with a charging connector 250 electrically connected to the battery 100 on the side away from the battery 100; the conductive terminal 140 is a socket terminal 140B; the mounting position 210 is a plug adapted to the socket terminal 140B and is provided on the second circuit board 220; the socket terminal 140B is detachably provided on the plug.

[0063] Embodiment 3

[0064] See also Figures 8 to 13 As shown, this embodiment provides an electronic cigarette, including a mouthpiece 300, a cigarette rod 400, an atomization module 500 and the above-mentioned battery module; the cigarette rod 400 is arranged in a hollow body structure, the atomization module 500 and the battery module are arranged in the cigarette rod 400 in sequence along the length direction of the cigarette rod 400, the mouthpiece 300 is located at one end of the cigarette rod 400 and is buckled and connected to the atomization module 500; the atomization module 500 is electrically connected to the discharge connector 230 of the battery module. Among them, a visual window 420 for observing the oil content in the oil storage bin 510 is opened on the side wall of the cigarette rod 400, which can facilitate the user to check the oil in the oil storage bin 510 in real time and add oil to the oil storage bin 510 in time.

[0065] Since the electronic cigarette is provided with a mouthpiece 300, a cigarette rod 400, an atomization module 500 and the above-mentioned battery module, and by setting the cigarette rod 400 as a hollow body structure, when assembling the electronic cigarette, it is only necessary to assemble the atomization module 500 and the battery module inside the cigarette rod 400 along the length direction of the cigarette rod 400 respectively, insert the discharge connector 230 of the battery module into the atomization module 500, so that electrical conduction is achieved between the battery module and the atomization module 500, and the mouthpiece 300 is snap-fitted and connected to the atomization module 500 at one end of the cigarette rod 400 close to the atomization module 500, and the assembly of the electronic cigarette can be completed. The assembly process is simple and convenient, and automated production can be realized, which is conducive to improving production efficiency and thus reducing production costs.

[0066] In a preferred embodiment, the atomization module 500 includes an oil storage bin 510, an air vent 520, a heating component 530, a first sealing layer 540 and a second sealing layer 550; the cigarette holder 300 is snap-fitted to one end of the oil inlet of the oil storage bin 510; the air vent 520 is located between the oil storage bin 510 and the cigarette rod 400, and is connected to the air outlet of the cigarette holder 300; the heating component 530 is arranged at the oil outlet of the oil storage bin 510, and is connected to the smoke inlet of the air vent 520; the first sealing layer 540 is arranged at the oil inlet of the oil storage bin 510, and forms an oil filling chamber 560 between the first sealing layer 540 and the air outlet of the cigarette holder 300; the second sealing layer 550 is arranged at one end of the oil storage bin 510 away from the cigarette holder 300.

[0067] Since the atomization module 500 is provided with an oil storage bin 510, a vent hole 520, a heating component 530, a first sealing layer 540 and a second sealing layer 550, the above components can be used in coordination with each other to not only atomize the tobacco oil for inhalation by the smoker, but also prevent the tobacco oil in the oil storage bin 510 from flowing out. Specifically, the heating component 530 and the cigarette holder 300 are connected to the vent hole 520 respectively, and the tobacco oil in the oil storage bin 510 is atomized to form smoke through the heating component 530, and the smoke enters the cigarette holder 300 along the vent hole 520 for inhalation by the smoker. In addition, by setting a first sealing layer 540 at the oil inlet of the oil storage bin 510, it is used to prevent the oil in the oil storage bin 510 from flowing out, and by forming an oil filling chamber 560 between the first sealing layer 540 and the mouthpiece 300 on the shell, the oil injector 600 can enter the oil filling chamber 560 from the air outlet of the mouthpiece 300, and pierce the first sealing layer 540 to enter the oil storage bin 510, so as to fill the oil storage bin 510 with oil.

In addition, by setting a second sealing layer 550 at one end of the oil storage bin 510 away from the mouthpiece 300, a cavity is formed between the second sealing layer 550 and the heating component 530, and the heating component 530 is connected to the smoke inlet of the vent 520 through the cavity, so that the smoke generated by the atomization of the oil can enter the mouthpiece 300 along the vent 520. Moreover, the second sealing layer 550 can also prevent smoke from diffusing into the cigarette rod 400, thereby ensuring that the electronic cigarette can be used normally.

[0068] In a preferred embodiment, the heating component 530 includes a ceramic heating core 531 and a sealing ring 532 , and the sealing ring 532 is sleeved on the outer peripheral side wall of the ceramic heating core 531 .

[0069] Since a sealing ring 532 is sleeved on the outer peripheral side wall of the ceramic heating core 531, not only can the ceramic heating core 531 be more firmly arranged at the oil outlet of the oil storage tank 510, but also the oil outlet of the oil storage tank 510 can be effectively prevented from leaking oil.

[0070] In a preferred embodiment, a buffer ring 533 is further provided between the sealing ring 532 and the oil outlet of the oil storage tank 510, and the buffer ring 533 and the sealing ring 532 are integrally formed. The buffer ring 533 includes two circles of buffer ring 533.

[0071] Since a buffer ring 533 is provided between the sealing ring 532 and the oil outlet of the oil storage tank 510 to improve the protection of the ceramic heating core 531, it can effectively prevent the performance of the ceramic core from being affected by excessive pressure during assembly or use.

[0072] In a preferred embodiment, the ceramic heating core 531 is arranged in a T-shaped structure, and a accommodating chamber 531A is arranged at one end of the ceramic heating core 531 close to the oil outlet of the oil storage tank 510, and the accommodating chamber 531A is connected to the oil storage tank 510; a current output contact 531B is arranged at one end of the ceramic heating core 531 away from the accommodating chamber 531A; a resistance wire 531C is electrically connected between the current output contacts 531B; the ceramic heating core 531 is electrically connected to the discharge connector 230 through the current output contact 531B.

In addition, since the ceramic heating core 531 is provided with a current output contact 531B at one end away from the buffer ring 533, the current output contact 531B abuts against the discharge connector 230 of the battery module, so that the ceramic heating core 531 and the battery module are electrically connected, and the ceramic heating core 531 is triggered to heat up under the action of the current, so that the oil inside the ceramic heating core 531 is atomized to generate smoke.

[0074] In a preferred embodiment, a groove 541 is provided on the first sealing layer 540; the groove 541 is located between the air outlet of the cigarette holder 300 and the oil inlet of the oil storage tank 510; a first through hole 542 is also provided on the first sealing layer 540; the air outlet of the cigarette holder 300 is connected to the ventilation hole 520 through the first through hole 542.

[0075] Since the first sealing layer 540 is provided with a groove 541, and the groove 541 is located between the air outlet of the cigarette holder 300 and the oil inlet of the oil storage tank, through the cooperation between the oil filling chamber 560 and the groove 541, when the smoke oil injector 600 enters the oil filling chamber 560 from the air outlet of the cigarette holder 300, it can more conveniently pierce the first sealing layer 540, thereby entering the oil storage tank to fill the oil storage tank with smoke oil. It should be noted that the first sealing layer 540 is made of a soft material, but is not limited to a silicone material. The material has good recovery performance, thereby ensuring that the smoke oil injector 600 still has a certain degree of sealing after being pierced and taken out.

[0076] In a preferred embodiment, the atomization module 500 further includes oil-absorbing cotton 570 , which is located between the heating component 530 and the second sealing layer 550 and is disposed in the placement cavity of the second sealing layer 550 .

[0077] By arranging the oil-absorbing cotton 570 between the heating component 530 and the second sealing layer 550 to absorb the tobacco oil flowing out from the oil outlet of the oil storage bin 510 or the ceramic heating core 531, it can effectively prevent the tobacco oil from flowing out and affecting the normal use of the electronic cigarette.

[0078] In a preferred embodiment, a tail cover 410 is further provided at one end of the cigarette rod 400 away from the cigarette holder 300, and the tail cover 410 is detachably provided on the cigarette rod 400; an air inlet hole 411 for gas circulation is provided on the tail cover 410; an electrode hole 551 and an air flow hole 552 located between the electrode holes 551 are provided on the second sealing layer 550; the discharge joint 230 is located in the electrode hole 551; the oil-absorbing cotton 570 is provided with a second through hole 571 connected to the electrode hole 551 and the air flow hole 552; one end of the air flow hole 552 is connected to the vent hole 520 through the second through hole 571, and the other end is connected to the air inlet hole 411, so that an air inhalation path is formed between the air inlet hole 411, the vent hole 520 and the cigarette holder 300. Among them, a microphone silicone is provided inside the tail cover 410.

[0079] Since the tail cover 410 is provided with an air inlet 411 for gas circulation, the external air can enter the interior of the cigarette rod 400 through the air inlet 411 when smoking. In addition, by providing the electrode hole 551 on the second sealing layer 550, the discharge terminal can pass through the second sealing layer 550 through the electrode hole 551 and abut against the current output contact 531B. In addition, by providing the air flow hole 552 on the second sealing layer 550, and connecting the two ends of the air flow hole 552 with the vent 520 and the air inlet 411 respectively, an inhalation path is formed between the air inlet 411, the vent 520 and the cigarette holder 300. That is, when the smoker inhales towards the cigarette holder 300, the air flow can enter the interior of the cigarette rod 400 from the air inlet 411, and then enter the cavity between the second sealing layer 550 and the heating component 530 from the air flow hole 552, and drive the smoke to enter the cigarette holder 300 along the vent 520, so as to achieve the purpose of smoking.
