Abstract

The utility model relates to an external type filter for an aquarium, which comprises a casing, a supporting plate for a water pump, gratings, a water inlet, a water outlet, etc. The utility model improves a casing with an opened cover and adopts a one-step formed cavity structure with four sealed wall faces, and both ends are compressed and sealed through end covers with seal rings. The structure disables the filtered and purified water to be polluted again, and the filth in the filter can not overflow to pollute grooves of an aquarium. The utility model also has the advantages of clean filtering material and convenient replacement.

Description

External type filter for aquarium

The utility model relates to the filter plant of aquaria.

Existing Aquarium filter is particularly put the too external filter of aquaria top, puts into filtering material in the container of spacious lid, with carrying out filter sterilization in the water suction filter in the aquaria, flows into aquaria with suction pump more again.Because filter covers structure for spacious, dust impurity on every side pollutes filter easily, influences its purification, bactericidal effect.For this reason, people develop a kind of filter with loam cake, are sealing and dustproof, adopt many bolt and nuts that loam cake and container is fastening, though solve pollution problem more so to a certain extent, the many nuts that at every turn get loose make troubles for the replacing filtering material.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of good seal performance is provided, and can effectively prevent the external Aquarium filter of the water pollution that outer bound pair has filtered.

The purpose of this utility model is achieved by the following technical solution: the external Aquarium filter comprises housing, water pump supporting plate, grid, water inlet and delivery port etc., housing adopts four one-time formed seal chamber structures of face, and the cavity two ends are drive end bearing bracket and rear end caps of band sealing ring.

Because the sealing of four walls of housing, two ends then compress sealing by the end cap of band sealing ring, extraneous dust, impurity etc. be not easy to after filtration, the water that purifies pollutes again, impurity, dirt in the filter also can overflow not gone into family's groove; The grid locating rack of setting up, but the capacity of different filtering materials in the regulated at will filter not only, and open an end end cap, can together pull out filtering material easily, be convenient to change; In addition, the housing one-shot forming, length can intercept as required, adapts to the needs of different length aquaria, and need not process specially.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the housing sectional view of band grid locating rack.

Below in conjunction with drawings and Examples the utility model is further elaborated.

See figures.1.and.2, the housing 7 of the present embodiment cavity that is rectangle substantially, four wall one-shot formings sealings, guide groove is arranged at the bottom, and water pump supporting plate 1 can pull out or push along guide groove.Housing 7 two sides have " ［ " shape grid locating rack 5, and grid 6 left and right sides have with " inner groovy that ［ " shape grid locating rack 5 matches and inlays, but with grid 6 polyliths of grid locating rack 5 interlocking, and the spacing between the grid 6 can arbitrarily be adjusted.Be embedded with 2 grids 6 in the present embodiment, cavity is separated into three joints, can put sponge, activated carbon, three kinds of filtering materials of biotype filter core respectively.The two ends of grid locating rack 5 are equipped with bolt, nut 2 respectively, and its position is corresponding with fastener hole on drive end bearing bracket 3 and the rear end cap 9, and when tightening up nut, bolt 2, drive end bearing bracket 3 and rear end cap 9 compress sealing ring simultaneously, and compress housing 7, form sealing.In the present embodiment, water inlet 4 is opened on drive end bearing bracket 3, and 8 of delivery ports are opened in the bottom surface of housing 7.Certainly, intake-outlet visual actual needs being set and being located at respectively on housing 7 or the end cap 3,9.

During use, water pump supporting plate 1 is pulled out, be used to bear water pump, the delivery port of water pump and the water inlet of filter 4 are connected, after the water that water pump draws up from aquaria entered housing 7 inner chambers, by grid 6 from level to level, the various filtering materials of process purified, sterilization, annotate back aquaria by delivery port 8 at last, finish the water in the aquaria is carried out circularly purifying.When changing filtering material, need only unclamp the nut 2 of end cap 3 and 9, pulling grid locating rack 5 can be pulled out the various filtering materials between the grid 6, so that replace or cleaning.

As seen, the utility model is a kind of good sealing effect, Shui nationality filter plant easy to use.
