WO2022100367A1 - Dual-air channel device preventing hole blockage, and aerosol generating device - Google Patents

Abstract

A dual-air channel device (1) preventing hole blockage, and an aerosol generating device. A first air channel (13) of an air flow sensor (16) and a second air channel (14) generating an aerosol are divided into two independent flow channels, such that a condensate generating the aerosol in the second air channel (14) cannot drip onto the air flow sensor (16) during reflux, thereby avoiding the risk of a short circuit. When the condensate flows back and blocks an atomizing assembly (17), normal operation of the air flow sensor (16) enables the atomizing assembly (17) to normally start to heat, such that a liquid blocking the atomizing assembly (17) is heated to re-form the aerosol; thus, blockage of the atomizing assembly (17), which is caused by the fact that the air flow sensor (16) cannot normally start due to sharing one air channel, is avoided. There is an angle between a third air channel (15) and the second air channel (14), such that when the aerosol generated in the second air channel (14) moves to the third air channel (15) by means of a smoking force of a user, the aerosol needs to pass through a corner formed at a junction between the second air channel (14) and the third air channel (15); thus, a part of the condensate generated in the second air channel (14) can be blocked, and the user is prevented from suctioning the condensate during smoking.
