The one-way switch 57 is openably and closably disposed between the air outlet 5303 and the interior of the battery shaft 31 in the air flow channel so as to be capable of being opened to allow air to flow through the air switch 55 and then through the air outlet 5303 into the interior of the battery shaft 31 upon a user's suction, and closed to prevent air from flowing from the interior of the battery shaft 31 to the air outlet 5303 and through the air switch 55 upon a user's reverse inhalation from the tail cap device 50.
In one embodiment, the one-way switch 57 is a plurality of silicone valves disposed on one side of the air outlet 5303. The plurality of silica gel valves are mutually unfolded along the airflow direction when the gas flows from the gas inlet holes 510 to the gas outlet holes 5303, so as to be opened and mutually closed along the airflow direction when the gas flows from the gas outlet holes 5303 to the gas inlet holes 510, thereby realizing the unidirectional circulation of the gas. In this embodiment, the fixing member 53 is made of a silicone material.
In another embodiment, the one-way switch 57 is a wind-blocking sheet disposed at one side of the air outlet 5303, the wind-blocking sheet opens the air outlet 5303 in the air flow direction when the air flows from the air inlet 5303 to the air outlet 5303, and closes the air outlet 5303 in the air flow direction when the air flows from the air outlet 5303 to the air inlet 510. In this embodiment, the fixing member 53 is made of a silicone material, and the windshield is a silicone sheet disposed on one side of the air outlet 5303.
Further, the fixing member 53 includes a light guiding column 532, and the light guiding column 532 is disposed transversely on the air inlet side a of the vent 5301 and directly faces the light emitting member on the pneumatic switch 55, so as to better display the working states of the pneumatic switch 55 and the electronic cigarette 100.
Further, the electronic cigarette 100 includes an insulating member 70 (as shown in fig. 3), and the insulating member 70 is disposed between the positive and negative terminals of the battery cell 33 and the battery rod 31 in an insulating manner, so as to prevent the positive and negative terminals of the battery cell 33 from contacting the battery rod 31.
Referring to fig. 6, during use, when the user sucks on the electronic cigarette 100, the external air passes through the air inlet hole 510 of the tail cap device 50 and the air inlet side a of the vent 5301 in the direction indicated by the arrow a, then flows through the pneumatic switch 55, and flows from the air outlet side b of the vent 5301, the air outlet hole 5303 and the inside of the battery rod 31 to the atomizing assembly. Due to the action of the suction force, the one-way switch 57 on the side of the air outlet 5303 is opened, and at the moment, the pneumatic switch 55 starts to work, the battery device 30 supplies electric energy, and the user can suck the food.
