Abstract

The invention provides a secondary filtering device, a secondary filtering assembly comprises a cone group, a dust guiding shell and a secondary dust collecting part, the bottom end of the cone group is communicated with the secondary dust collecting part through the dust guiding shell, the dust guiding shell comprises a first dust guiding channel with a direct dust guiding area and an indirect dust guiding area, the direct dust guiding area is communicated with the secondary dust collecting part, and the indirect dust guide area is arranged at the upstream of the direct dust guide area and is provided with a dust guide plate at the bottom. The invention further provides a filtering device. The filtering device comprises the secondary filtering assembly. The secondary filtering assembly and the filtering device do not generate direct retention of dust.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a secondary filter assembly and a filter device. Background technique [0002] In the existing dust collection equipment, the dust particles in the dust-laden fluid are filtered and separated by the filter device in the main machine. The filter unit usually includes a secondary filter assembly to separate dust and fluid. However, the dust guide housing of the secondary filter assembly is assembled with the fluid housing of the fluid channel assembly, and the fluid channel in the fluid housing is in the dust guide housing, so that a dust retention area is formed in the dust guide channel of the dust guide housing, resulting in Dust cannot be guided smoothly into the dust collection chamber. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a secondary filter assembly, the secondary filt...
