COMPOSITE VACUUM CLEANER HAVING WATER TANK
Document Type and Number:
WIPO Patent Application WO/2021/129518
Kind Code:
A1
Abstract:
A composite vacuum cleaner (100) having a water tank (3), comprising a vacuum cleaner body (41) and a flat mop (42) that is connected to the vacuum cleaner body (41); the vacuum cleaner body (41) is provided with a dust suction port (412); the flat mop (42) and the dust suction port (412) are disposed back to back; the flat mop (42) comprises a housing (421) that is used for forming a containing space, a through hole (422) that is provided on the housing (421), a first air hole that is used for connecting the inside and the outside of the housing (421), and a sealing mechanism (424) that is used for sealing or exposing the first air hole; a water storage space is provided within the water tank (3); the water tank (3) further comprises at least one drainage hole (31) that is communicatingly provided with the water storage space, and an exhaust component (30); the exhaust component (30) comprises a through hole (33) that communicates with the atmosphere, at least one air intake hole (32) that is communicatingly provided with the water storage space, and an air intake channel (331) that is used for placing the air intake hole (32) in communication with the through hole (33), the diameter of the through hole (33) being greater than that of the air intake hole (32). When the composite vacuum cleaner (100) is in use, air pressure inside and outside of the housing (421) of the flat mop (42) may be in communication, such that water within the flat mop (42) successfully seeps out; and when the flat mop (42) is not in use, a pressure difference is generated inside and outside of the housing (421) of the flat mop (42) so as to prevent water from continuing to seep out from within the housing (421) and affecting usage.
