Detailed Description

The utility model is described in further detail below with reference to the drawings and the specific examples. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1-2, the embodiment specifically provides a brush self-cleaning filter core, which comprises a filter cartridge 1, wherein a reciprocating mechanism 2 is axially arranged in the filter cartridge 1, a driving end of the reciprocating mechanism 2 is provided with an annular brush 3, brush hair 33 ends of the annular brush 3 are abutted against the inner wall of a filter layer 12 of the filter cartridge 1, and the annular brush 3 is positioned at the upper part of the filter layer 12 of the filter cartridge 1. The reciprocating mechanism 2 is controlled to work, the annular brush 3 is driven to reciprocate up and down, the purpose of cleaning the inner wall of the filter element up and down in a reciprocating manner can be achieved, and the phenomenon that the filter flow is influenced by arranging a large-volume brush in the filter element is avoided.

The filter cartridge 1 includes: top cover 11, filter layer 12 and bottom cover 13; the upper and lower ends of the filter layer 12 are respectively provided with a top cover 11 and a bottom cover 13, and three fan-shaped grooves 14 are circumferentially arranged on the top cover 11 to form a liquid inlet.
