[0031] The embodiment of the utility model provides an electronic cigarette, which can improve the problem of a slow speed of the oil storage tank replenishing oil to the oil storage cotton when the user inverts the electronic cigarette to refill oil.

[0032] like Figures 1 to 3 As shown, the embodiment of the utility model provides an electronic cigarette, which includes: a housing 100, a mouthpiece 200 and an oil storage part 300, the mouthpiece 200 is arranged at one end of the housing 100, and the mouthpiece includes an airway. The oil storage part 300 includes an oil storage tank 310 and oil storage cotton 320, the oil storage tank 310 is arranged in the housing 100, the oil storage tank 310 includes a first cavity 311, and the tobacco oil can be stored in the first cavity 311, the first cavity 311 includes at least two oil outlet holes 3111 on the side close to the mouthpiece 200, and the oil storage cotton 320 is located between the mouthpiece 200 and the oil outlet hole 3111, and the tobacco oil in the oil storage tank 310 can flow into the oil storage cotton 320 through each oil outlet hole 3111 by inverting the electronic cigarette.

[0033] The technical solution of the utility model adopts the provision of an oil storage tank 310, which can store tobacco oil, which is beneficial to expanding the tobacco oil storage capacity inside the electronic cigarette and prolonging the smoking time of the user. By providing at least two oil outlet holes 3111 in the first cavity 311 of the oil storage tank 310, when the electronic cigarette is inverted to refill oil, the tobacco oil at different oil outlet holes 3111 has a liquid level difference, so that a pressure difference can be generated inside the first cavity 311, so that the ventilation rates at different oil outlet holes 3111 are different, and the ventilation rate at the oil outlet holes 3111 with low pressure is high, thereby improving the smoothness of the oil outlet of the oil storage tank 310, avoiding the situation where the oil storage tank 310 refills the oil storage cotton 320 slowly, and making the oil outlet speed of the oil storage tank 310 faster, which is convenient for user experience.

[0034] In one embodiment, the oil storage tank 310 is detachably disposed inside the housing 100, and the user can refill the first cavity 311 of the oil storage tank 310 through the oil outlet 3111, or directly replace the oil storage tank 310 that has run out of oil. The technical solution of the utility model facilitates replacing the oil storage tank 310 or refilling the oil storage tank 310 when the oil in the oil storage tank 310 runs out by detachably disposing the oil storage tank 310 inside the housing 100, which is conducive to improving the user experience. Furthermore, the housing 100 can be set to a transparent style to better observe the remaining oil content in the first cavity 311.

[0035] like Figures 1 to 3 As shown, the electronic cigarette further includes a mouthpiece plug 210, which can block the mouthpiece 200 or be separated from the mouthpiece 200.
