The sealing member (40) is sleeved on an atomization top seat (21) and is matched with the outer sidewall of the atomization base (20) to form a ventilation channel. A first end of the ventilation channel is communicated with the outside atmosphere, and a second end of the ventilation channel is communicated with the liquid storage bin (13), wherein the ventilation channel is of a one-way flow guide structure, allows the outside atmosphere to enter the liquid storage bin (13) and prevents liquid in the liquid storage bin (13) from leaking. The ventilation channel formed by the matching the atomization base (20) with the sealing member (40) is high in section stability and is less influenced by part tolerance and assembly tolerance, such that the smoothness of the ventilation channel is improved. The sealing member (40) only needs to seal the atomization base (20), such that the formation of the ventilation channel is indirectly ensured, and the requirements on the performance and the size of the sealing member (40) are reduced. The one-way flow guide structure prevents the liquid in the liquid storage bin (13) from leaking to an atomization cavity (23), thereby improving the performance of the electronic atomization device.

In this embodiment, the groove 50 is a continuous curved channel to form a Tesla valve; the extension direction of the Tesla valve channel is on the first surface 215 or the second surface 216 of the atomizing top seat 21 from close to the storage One end of the liquid storage tank 13 extends to an end away from the liquid storage tank 13 . According to the characteristics of the Tesla valve, the flow is smooth in the forward direction and blocked in the reverse direction. The Tesla valve formed by the groove 50 enables the outside air to pass through the Tesla valve in the same direction during ventilation, which can allow the outside air to pass through the ventilation channel almost unobstructed, thereby entering the liquid storage tank 13; the liquid in the liquid storage tank 13 Passing through the Tesla valve in the reverse direction, due to the blocking effect of the Tesla valve itself, the liquid can be prevented from entering the atomization chamber 23 during the use of the electronic atomization device.

In other embodiments, the grooves 50 may also be of other structures, as long as the ventilation in the forward direction is smooth and the flow of the liquid in the reverse direction is blocked, that is, unidirectional flow. A one-way valve may also be provided on the groove 50 , and the one-way valve enables the outside air to enter the liquid storage bin 13 smoothly, and prevents the liquid in the liquid storage bin 13 from flowing into the atomization chamber 23 . It is also possible to set a liquid-proof and breathable membrane on the groove 50, and the outside atmosphere can pass through the liquid-proof and breathable membrane, so that the outside atmosphere can be circulated on both sides of the filter membrane, and the liquid in the liquid storage tank 13 cannot pass through the liquid-proof and breathable membrane, and then The liquid is prevented from entering the atomizing chamber 23 .

The atomizing assembly in this application includes an atomizing seat and a sealing member, the atomizing seat includes an atomizing top seat and an atomizing base, and the sealing member is sleeved on the atomizing top seat. By arranging grooves on the outer side wall of the atomizing top seat, a ventilation channel is formed in cooperation with the sealing element. Since the seal is sleeved on the atomizing top seat, and the groove is arranged on the outer side wall of the atomizing top seat, the seal covers the groove, and the ventilation passage formed by the groove and the seal has high cross-section stability and is subject to Part tolerances and assembly tolerances have less influence, which improves the smoothness of the ventilation passages. The seal only needs to seal the atomizing seat, which indirectly ensures the formation of the ventilation channel and reduces the performance and size requirements of the seal.

The above descriptions are only part of the embodiments of the present application, and are not intended to limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the contents of the description and drawings of the present application, or directly or indirectly applied to other related The technical field is similarly included in the scope of patent protection of this application.
