Description

Technical Field

[0001] The utility model relates to a fish tank water filter, and more specifically, the utility model mainly relates to an external filter which is convenient to clean. Background Art

[0002] In modern home life, the safety and purity of water quality are of vital importance. The fish tank external filter on the market is favored by many families for its efficient filtering function. However, the traditional external filter often needs to be disassembled when cleaning, which is not only cumbersome to operate, but also brings a lot of trouble to users due to its heavy weight. Therefore, it is necessary to study and improve the structure of the traditional fish tank external filter. Utility Model Content

[0003] One of the purposes of the present invention is to provide an external filter that is easy to clean in order to address the above-mentioned shortcomings, so as to solve the technical problems in the prior art that similar external filters are difficult to clean and cannot improve their filtering effects.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides an easy-to-clean external filter, comprising a box body, a filter chamber installed on the upper part of the box body, the filter chamber is connected to the water outlet, the filter chamber is also connected to the upper part of the primary filter chamber, a sewage pipe is also provided at the lower part of the primary filter chamber, and a sewage valve is installed on the sewage pipe; a water pump is also installed in the box body, the water inlet end of the water pump is connected to the water inlet pipe, and the water outlet end of the water pump is connected to the primary filter chamber.

[0006] Preferably, a further technical solution is that a transverse diversion slope is provided on the water outlet.

[0007] A further technical solution is that an isolation cage is installed on the water inlet of the water inlet pipe.

[0008] A further technical solution is that the interior of the primary filter cavity is filled with filter cotton or filter mesh.

[0009] Compared with the prior art, one of the beneficial effects of the utility model is that by adding a front primary filter chamber in the box body, the sewage entering the box body first enters the primary filter chamber. At this time, larger debris such as fish feces, mud, rotten aquatic plants, etc. will be deposited to the bottom of the chamber under the action of gravity, while the cleaner water will continue to rise and flow into the filter chamber, and undergo secondary fine filtration through the filter medium in the filter chamber. The dirt and debris deposited at the bottom of the primary filter chamber can be discharged through the drain pipe at the bottom of the primary filter chamber, which is convenient for cleaning and operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram for illustrating an embodiment of the utility model.

[0011] Figure 2 for Figure 1 Schematic diagram of the axial structure.

[0012] In the figure, 1 is a box body, 2 is a filter chamber, 3 is a water outlet, 4 is a diversion slope, 5 is a primary filter chamber, 51 is filter cotton, 6 is a sewage pipe, 61 is a sewage valve, 7 is a water pump, 8 is a water inlet pipe, and 81 is an isolation cage. DETAILED DESCRIPTION

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] refer to Figure 1 As shown, one embodiment of the utility model is an external filter that is easy to clean, including a box body 1, a filter chamber 2 is installed on the upper part of the box body 1, the filter chamber 2 is connected with the water outlet 3, and the filter chamber 2 is also connected with the upper part of the primary filter chamber 5, so that the water in the primary filter chamber 5 can flow from the upper part into the filter chamber 2 for secondary filtration. In addition, a sewage pipe 6 is also provided at the lower part of the aforementioned primary filter chamber 5, and a sewage valve 61 is installed on the sewage pipe 6. The sewage pipe 6 can be opened or closed by the sewage valve 61, so that the impurities in the primary filter chamber 5 can be controlled to be discharged together with the water, which can be replaced by cleaning; a water pump 7 is also installed in the aforementioned box body 1, and the water inlet end of the water pump 7 is connected with the water inlet pipe 8, and the water outlet end of the water pump 7 is connected with the primary filter chamber 5, so that the sewage in the fish tank can be pumped into the primary filter chamber 5 by the water pump.

[0015] In this embodiment, a pre-primary filter chamber is added to the housing 1 so that the sewage drawn into the housing 1 first enters the primary filter chamber 5. At this time, larger debris such as fish feces, mud, rotten aquatic plants, etc. will be deposited to the bottom of the chamber under the action of gravity, while cleaner water will continue to rise and flow into the filter chamber, and undergo secondary fine filtration through the filter medium in the filter chamber 2. The dirt and debris deposited at the bottom of the primary filter chamber 5 can be discharged through the drain pipe 6 at the bottom of the primary filter chamber 5, which is convenient for cleaning and operation.

[0016] Furthermore, in order to reduce the flow rate of filtered water and reduce noise, a transverse guide slope 4 can be added to the water outlet 3; at the same time, in order to prevent the water pump 7 from sucking larger impurities in the fish tank into the primary filter chamber 5, an isolation cage 81 can be installed on the water inlet of the water inlet pipe 8. More preferably, in order to improve the filtering effect of the primary filter chamber 5, in this embodiment, the primary filter chamber 5 can be filled with filter cotton 51, and the sewage entering the primary filter chamber 5 can be assisted by the filter cotton 51.

[0017] It can be seen from the filter structure described in the above embodiment that the external filter adds an innovative pre-filter chamber on the basis of the traditional design. This pre-filter chamber has a layer of high-efficiency filter medium built in, which can intercept a large amount of impurities and particulate matter in the initial stage, effectively extending the service life of the main filter. When the water flow is sucked into the filter, it will first enter this pre-filter chamber. Here, larger debris such as fish feces, mud, rotten water plants, etc. will be deposited to the bottom of the chamber under the action of gravity, while the cleaner water will continue to rise and undergo secondary fine filtration through the filter medium, and finally obtain purer water quality.

[0018] More importantly, the drain switch (drain pipe 6 and drain valve 61) is designed at the bottom of the aforementioned pre-filter chamber 5. When the filter needs to be cleaned, the user does not need to disassemble the heavy machine, but only needs to gently twist the drain switch, and the dirt and debris deposited at the bottom of the pre-filter chamber can be easily discharged. This simple and practical design greatly reduces the labor intensity of the user and also saves cleaning time. In addition, this design is also helpful for environmental protection because it reduces the need for frequent replacement of filters and reduces the pressure of discarded filters on the environment. At the same time, since the pre-filter chamber can effectively capture large particles of impurities, this also means that the replacement frequency of the main filter can be reduced, thereby reducing the overall cost of use.

[0019] In short, this new type of external filter, with its front filter chamber and convenient sewage switch design, not only improves the filtration efficiency, but more importantly, greatly simplifies the cleaning process, making daily maintenance easier. Its launch undoubtedly provides a more ideal choice for families pursuing high-quality life, and also reflects the trend of household products towards more humane and environmentally friendly development. With people's continuous pursuit of healthy quality of life, such innovative designs will surely gain more favor in the market.
