Title:
AIR INTAKE LIQUID BLOCKING STRUCTURE, ATOMIZER, AND AEROSOL GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/100170
Kind Code:
A1
Abstract:
The utility model provides an air intake liquid blocking structure, an atomizer, and an aerosol generating device, the air intake liquid blocking structure comprising an outer sleeve and an air intake liquid blocking member. The air intake liquid blocking member comprises an air intake tube and at least two liquid blocking rib groups; the air intake tube comprises an open end, a closed end, and an outer peripheral wall; the open end is provided with an air intake hole; the outer peripheral wall is provided with air guide holes; each liquid blocking rib group comprises at least one liquid blocking section arranged along the circumferential direction; at least one liquid dropping notch is defined between liquid blocking sections located on the same circumference; and the projections of liquid dropping notches in adjacent liquid blocking rib groups along the axial direction of the air intake tube are staggered from each other and communicated with each other along the axial direction of the air intake tube to form liquid dropping passages. In the present utility model, by providing the liquid blocking rib groups and defining a plurality of liquid dropping passages between the liquid blocking rib groups, the liquid entering the outer sleeve from an atomization cavity can be absorbed by the liquid blocking rib groups, thereby preventing affecting the service life of a power supply device due to liquid leakage to the power supply device.
