The utility model relates to a diffusion filter. The diffusion filter comprises a housing with a three-way cavity and a filter structure arranged inside the housing, wherein the housing is divided into a horizontal segment, a tapered concentric reducer, and a vertical segment which is perpendicularly connected with the horizontal segment, wherein the tapered concentric reducer and the horizontal segment are integrally manufactured and have the same axial line; the end opening of the vertical segment is as a fluid inlet; the smaller end of the concentric reducer is a fluid outlet; a guide plate is arranged inside the concentric reducer; the end opening of the horizontal segment is a mounting inlet of the filter structure; the mounting inlet is connected with a flange cover through a flange; a supporting ring is arranged on the flange cover; a supporting seat is arranged on the inner wall of one side, near the concentric reducer, of the horizontal segment; the two ends of the filter structure are respectively limited by the supporting ring and the supporting seat. By adopting the scheme, the supporting seat and the supporting ring are adopted to connect the filter structure in a clamping manner, so as to enable the filter structure to be mounted and demounted conveniently; the wave-shaped bending part for filtering is arranged to be a cylindrical structure to enlarge the filtering area and improve the pump efficiency; the arrangement of the guide plate enables the fluid to be stable, so as to prolong the service life of the pump.
