WIPO Patent Application WO/2019/075783
Kind Code:
A1
Abstract:
Disclosed is a dust cup having a double spiral dust-air separating structure. The dust cup comprises: a cup body; and a double spiral filtering assembly arranged in the cup body, which is characterized in that the double spiral filtering assembly comprises two air guide pipes arranged in the same space in the cup body and air filtering columns arranged in the air guide pipes; and the outer side wall of each air filtering column is spaced apart at a certain distance from the inner side wall of each air guide pipe, so as to form an air channel located therebetween. According to the present invention, the convenience of disassembly and cleaning can be improved while the structural complexity of components and parts is reduced, and the manufacturing complexity is also reduced, so that the manufacturing costs are significantly reduced, and a higher filtering efficiency is further achieved.
