Title:
ELECTRONIC CIGARETTE ATOMIZER AND ELECTRONIC CIGARETTE
Document Type and Number:
WIPO Patent Application WO/2019/242641
Kind Code:
A1
Abstract:
An electronic cigarette atomizer, comprising a housing (8). A top cover (9) is provided on the top of the housing (8). An e-liquid tank (12), an atomizing member (3), a connecting sleeve (22), and an atomizing cotton (14) connecting the e-liquid tank (12) and the atomizing member (3) are provided in the housing (8). An e-liquid inlet hole (2201) for connecting the e-liquid tank (12) and the atomizing cotton (14) is formed on the connecting sleeve (22). The lower part of the connecting sleeve (22) is sleeved on the upper part of an outer sleeve tube (24). The outer sleeve tube (24) is sleeved on the atomizing cotton (14), and a first e-liquid hole (2401) for connecting the e-liquid inlet hole (2201) and the atomizing cotton (14) is formed on the outer sleeve tube (24). The top cover (9) can drive the connecting sleeve (22) to rotate circumferentially and open or close the e-liquid inlet hole (2201). The electronic cigarette atomizer further comprises a buffer mechanism for providing a buffer effect for the stress between the connecting sleeve (22) and the outer sleeve tube (24) when the connecting sleeve (22) is rotated circumferentially. Thus, the production time is short, the production costs are low, and the sealing effect is good; an e-liquid injection hole (903) is not opened during air adjustment, thereby avoiding e-liquid leakage and suction of e-liquid.
