Title:
HEPA SELF-CLEANING DEVICE AND HEPA CLEANING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/036040
Kind Code:
A1
Abstract:
A HEPA self-cleaning device and a cleaning method, the device comprising a rotating cleaning body (100) which is used to clean a HEPA assembly (200); the rotating cleaning body (100) comprises a frame structure for the placement of the HEPA assembly (200), as well as an airway structure; and the airway structure is in communication with an air source. When the HEPA assembly (200) is placed in the frame structure, the air source operates so as to form an airflow from the outside of the HEPA assembly (200) to the inside thereof such that dirt on the HEPA assembly (200) is suctioned into the airway structure and discharged from the airway structure. Using the airway structure in combination with a suction assembly of a vacuum device forms an airflow for cleaning a HEPA so as to separate contaminants attached to the HEPA to thereby achieve the purpose of cleaning a HEPA, and a vacuum structure may further be combined so as to collect HEPA contaminants to achieve automatic and efficient HEPA cleaning.
