Description

Filtering structure and dust collection device using same

Technical Field

The utility model relates to the technical field of dust collectors, in particular to a filtering structure and a dust collection device using the same.

Background

In the dust collector technology, the sealing structure among the dust barrel, the filter element and the fan is critical to the performance of the dust collector. However, many portable cleaners on the market today have a problem of poor reliability of the sealing structure, resulting in a gap during use, so that part of the air flows directly from the gap without being filtered, rather than entering through the suction inlet, which greatly reduces the use efficiency of the cleaner.

In order to solve the above problems, in the prior art, as in the chinese patent No. CN201020501935.5 (bulletin No. CN 201759487U), the scheme of installing a sealing ring between the air outlet wall and the hepa is disclosed, which prevents the phenomenon that air flows out from the gap between the hepa and the air outlet wall to be insufficiently filtered, however, the scheme in the above patent generates larger friction with the air outlet wall when installing or replacing the hepa, which reduces the service life of the sealing member, and because the friction between the sealing ring and the air outlet wall is larger, the surface near the air outlet is damaged when replacing the sealing ring, which is not easy to replace.
