Title:
CLEANING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/151374
Kind Code:
A1
Abstract:
A cleaning device comprises a main body (100), a disengagement device (10) and an HEPA assembly (200). The HEPA assembly (200) is positioned on an air flow path of the main body (100). The disengagement device (10) is used to detachably fix the HEPA assembly (200) to the main body (100). The disengagement device (10) comprises a button (1), an engagement fastener (2) and an elastic member (3). The button (1) is provided at an angle to the engagement fastener (2). The engagement fastener (2) remains engaged with the main body (100) by means of an elastic force of the elastic member (3). When the button (1) moves in a first direction, the engagement fastener (2) is driven to move in a second direction, thereby causing an engagement end of the engagement fastener (2) to separate from the main body (100). The disengagement device (10) of the cleaning device simplifies a disengagement method and a disengagement process.
