fish tank filter

Abstract

The invention discloses a fish tank filtering device, and relates to the technical field of water quality filtration in the fish tank. The fish tank filtering device comprises a sleeve; a primary power device, a filtering assembly and a secondary powder device are distributed in sequence from top to bottom in the sleeve; the primary power device comprises an annular top plate; a boss-shape mounting shell is fixed to an opening of the middle of the annular top plate in a matched mode; water outlets are uniformly formed in the side wall of the mounting shell; a mounting opening is formed in the top of the mounting case; a motor A is fixed to the mounting opening in a matched mode; a spiral oar A is fixedly installed at an output end of the motor A in the vertical downwards direction; the annular top plate is fixedly connected to a sleeve ring in a sleeved mode; a retaining ring is rotatably connected with the outside of the annular top plate in a sleeving mode above the sleeve ring; the retaining ring and the sleeve ring are matched; both the retaining ring and the sleeve ring are provided with water through holes; the sleeve ring is fixedly connected with the sleeve in a sealing mode. The fish tank filtering device has the advantages of being capable of comprehensively filtering water, and being good in filtering effect and high in efficiency; meanwhile, the utilization efficiency of filtering cotton is improved, and the filtering cotton is convenient to clean and replace.

Description

technical field [0001] The invention relates to the technical field of water quality filtration in fish tanks. Background technique [0002] When filtering the water in the fish tank, there are many problems in the traditional filter. On the one hand, the overall filtering effect on the water is poor, for example, it is difficult to filter and remove the impurities falling on the bottom of the fish tank and on the water surface; The position is fixed, resulting in low overall filtration efficiency of water; on the other hand, the filter cotton in the traditional filter is used on a flat surface, the utilization rate of the filter cotton is low, and the cleaning and replacement of the filter cotton is inconvenient. We have invented a kind of fish tank filtering device for this reason, can effectively solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fish tank filter device for the above ...
