Title:
ATOMIZATION ASSEMBLY AND ELECTRONIC ATOMIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/095771
Kind Code:
A1
Abstract:
An atomization assembly (1) and an electronic atomization device. The atomization assembly (1) comprises a liquid storage bin (13), an atomization base (20), and a sealing member (40). 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.
