In addition, application number is that the Chinese utility model patent of 96246113.X and 200320110635 discloses respectively the auto purification filter that centering rotating shaft scrubbing cleaning brush is installed in filter core.When needing cleaning, rotate external rotating shaft handle, make the cleaning brush rotation, can remove the impurity of cartridge surface.Yet there is following obviously limitation in above-mentioned prior art: 1) because filter housings is passed in the cleaning brush rotating shaft, therefore be difficult to guarantee to be not suitable for poisonous, inflammable medium without leaking; 2) cleaning brush has occupied whole space in filter core, and the resistance when having increased Fluid Flow in A is not suitable for large diameter filter core.

Summary of the invention

The object of the invention is to: for the shortcoming that above-mentioned prior art exists, propose a kind of self-cleaning filter without leakage and compact conformation, thereby can satisfy the demand of poisonous inflammable medium and large specification filtration.

In order to reach above purpose, self-cleaning filter of the present invention comprises the housing with import and outlet, the barrier film that is separated out power drive chamber, bottom and filter chamber, middle and upper part body is housed in described housing, and described filter chamber body is equipped with and is separated out the tubular element that import is treated filter chamber and exported the filtration chamber; The track rotating disk that drives with the coaxial track of tubular element brush rotating disk and power set is equipped with respectively in the inboard of described barrier film and the outside; The rotation active shaft coupling coaxial with external gear is equipped with at peripheral at least one place of described track rotating disk, described track brush rotating disk and described active magnetic shaft coupling correspondence position are equipped with the passive magnetic shaft coupling coaxial with the brush holder support of track brush, have the bristle that contacts with the tubular cartridge surface on described brush holder support; Described external gear and the ring gear engagement that is fixed on the barrier film outside, the center of circle of described ring gear is positioned on the axis of described tubular filter core.

When driven by motor track turntable rotation, will drive the active shaft coupling and revolve round the sun thereupon, be somebody's turn to do simultaneously the active shaft coupling under the engagement of interior external gear, also around self axis rotation.Under magneticaction, driven shaft coupling will drive track brush synchronizes with shaft coupling initiatively and revolves round the sun and rotation, thereby brushes cleaning along the inner surface of tubular filter core.Adopted magnetic shaft coupling because the present invention is ingenious, guaranteed that therefore without leaking, the special type that is fit to the poisonous inflammable medium of filtration is filtered; And reasonably the revolution motion mode that combines with rotation not only makes track brush configuration compactness, can not increase filtration resistance, and no matter the filter core internal diameter is much all can effectively clear up.
