[0025] The atomization chamber 2 is at least partially arranged in the communication passage 11, and the atomization chamber 2 comprises a top cover 21, and an oil inlet hole 211 is arranged on the peripheral surface of the top cover 21, and the atomization substrate in the oil storage cavity can enter the atomization chamber 2 through the oil inlet hole 211. Specifically, the top cover 21 can have a first position and a second position, and a user can change the position of the top cover 21 through rotation, push-pull or the like, and it is easy to understand that the switching between the first position and the second position can also be realized through the movement of the top cover 21, such as translation, rotation or a combination of the two, and when the top cover 21 is in the first position, at least part of the oil inlet hole 211 is exposed in the oil tank 1, and when the top cover 21 is in the second position, the oil inlet hole 211 is located in the communication passage 11 and is closed by the chamber body forming the communication passage.

Similarly, the guide rod 212 can completely penetrate the cylindrical structure 221 through the first guide groove 2211, or can not penetrate the cylindrical structure 221.
[0027] In order to drive the top cover 21 to move to the first position or the second position, the atomization chamber 2 further comprises a knob sleeve 23, the knob sleeve 23 comprises a knob part 231 and a sleeve part 232 connected with each other, the cylindrical structure 221 is sleeved in the inside of the sleeve part 232, and a second guide groove 2321 spirally ascending along the circumference is arranged on the circumferential surface of the sleeve part 232; the guide rod 212 passes through the first guide groove 2211 and is inserted into the second guide groove 2321, and the guide rod can move along the extension direction of the second guide groove in the second guide groove.

[0029] In order to limit the stroke of the top cover 21 and avoid the top cover 21 being in an unexpected position, the knob sleeve 23 is further provided with a first limiting protrusion, and the electronic atomization equipment is further provided with two second limiting protrusions, when the user rotates the knob part 231 in the first direction and the top cover 21 moves upward to the first position, the first limiting protrusion and one of the second limiting protrusions abut to make the top cover 21 unable to continue to move upward, and when the user rotates the knob part 231 in the second direction and the top cover 21 moves downward to the second position, the first limiting protrusion and the other second limiting protrusion abut to make the top cover 21 unable to continue to move downward.
[0030] In order to realize rapid oil supply, the oil inlet hole can be multiple, and the multiple oil inlet holes are uniformly distributed on the circumferential surface of the top cover.
[0031] In some embodiments, the guide rod 212 has two, which are oppositely arranged on both sides of the top cover 21, the first guide slot 2211 has two, which are arranged one by one with the guide rod 212, and the second guide slot 2321 has two, which are arranged one by one with the guide rod 212. Through the above arrangement, the electronic atomization device can have two sets of symmetric driving structures of the top cover 21, and when the user drives the top cover 21 by rotating the knob part 231, the movement of the top cover 21 can be more balanced, smooth and smooth.
[0032] In some embodiments, in order to avoid slipping when the user rotates the knob part 231, the knob part 231 is partially exposed outside the electronic atomization device, and the knob part 231 is provided with an anti-slip structure. The anti-slip structure can be an anti-slip groove, an anti-slip protrusion, or an anti-slip pattern, etc., without specific limitation.
[0033] In order to avoid leakage or flow of the atomization substrate through an undesirable position, a first seal 41 is arranged between the top cover 21 and the oil tank 1, and a second seal 42 is arranged between the cylindrical structure 221 and the sleeve part 232. The electronic atomization device of the present application can also include a mist outlet pipe 5, one end of which is sleeved with the top cover 21, and the other end is in communication with the atmosphere.

The shape and number of the seals in the present application can be selected differently according to actual work needs, without specific limitation.
[0034] In actual use, it may occur that when the top cover 21 is in the first position, the height of the oil inlet hole 211 is too high, and when the atomization substrate in the oil tank 1 is not much left, the height of the remaining atomization substrate is lower than that of the oil inlet hole 211, so that the remaining atomization substrate is difficult to enter the atomization chamber through the oil inlet hole 211, causing waste. Therefore, in order to avoid waste and maximize the use of the atomization substrate in the oil tank 1, when the top cover 21 is in the first position, the height of the lowest point of the oil inlet hole 211 is lower than or equal to the height of the lowest point of the oil tank 1.
