Title:
DUAL AIR PASSAGE INTAKE STRUCTURE, POWER SUPPLY DEVICE, AND AEROSOL GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/180194
Kind Code:
A1
Abstract:
A dual air passage intake structure (10) used for an aerosol generating device. The dual air passage intake structure (10) comprises a base (11) and a sensor (12). The base (11) is provided with a sensing cavity (101); the sensing cavity (101) is communicated with an air outlet passage of the aerosol generating device; a mounting portion (102) is provided in the sensing cavity (101); the mounting portion (102) is provided with a mounting cavity (103); the sensor (12) is mounted on the mounting portion and seals the mounting cavity (103); the base (11) is provided with air inlets (104) and a communicating hole (105); the air inlets (104) are communicated with the sensing cavity (101) and the outside atmosphere; the communicating hole (105) is communicated with the mounting cavity (103) and the outside atmosphere; the mounting portion (102) is provided with a communicating groove (106); the communicating groove (106) is communicated with the mounting cavity (103) and the sensing cavity (101); and a cross sectional area of the communicating groove (106) and/or a cross sectional area of the communicating hole (105) is smaller than a cross sectional area of each air inlet (104). According to the dual air passage intake structure (10), the air pressure of both sides of the sensor (12) can also be maintained consistent in the case of a mistaken trigger, thereby ensuring that the sensor (12) would not be triggered by mistake. Also provided are a power supply device having the dual air passage intake structure (10) and an aerosol generating device having the power supply device.
