[0027] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] According to one embodiment of the present application, a fish tank filter is provided. The fish tank filter includes a housing 1, a cleaning assembly 2 and a detection device. The housing 1 has a cavity 11 inside, a water inlet 12 communicating with the cavity 11 is provided at the top of the housing 1, and a water outlet 13 communicating with the cavity 11 is provided at the bottom of the housing 1. The cleaning assembly 2 is arranged in the cavity 11, and the cleaning assembly 2 includes a filter 21 and a purification section 22. The cavity 11 is divided into a first chamber 111 and a second chamber 112 by the filter 21. The first chamber 111 is communicated with the water inlet 12, and the purification section 22 is arranged in the second chamber 112, wherein the water inlet 12, the first chamber 111, the cleaning assembly 2 and the water outlet 13 are arranged in the housing 1 from top to bottom in sequence; the detection device includes a detection member and a reflux pipe, one end of the reflux pipe is connected to the end of the housing 1 near the water inlet 12, and the other end of the reflux pipe is connected to the end of the housing 1 near the water outlet 13, and the reflux pipe is connected to the cavity 11.

[0033] like Figures 1 to 4 As shown, the housing 1 is a rectangular parallelepiped structure. The length of the housing 1 is 1175 mm, the width is 750 mm, and the height is 510 mm. The housing 1 has a cavity 11 inside. The water in the fish tank or fish pond enters the cavity 11, is filtered and purified in the cavity 11, and then is discharged.

[0034] Of course, in the embodiment of the present application, the housing 1 is not limited to the above size and structure, and those skilled in the art can configure it according to actual needs. For example, the housing 1 can also be a cube, a columnar structure, etc.

[0035] The top of the housing 1 is provided with a water inlet 12. The port of the water inlet 12 protrudes from the upper surface of the housing 1 so as to be connected with an external pipeline so that water in the fish pond or fish tank enters the cavity 11 through the pipeline.

[0036] The bottom of the housing 1 is provided with a water outlet 13. The water inlet 12 and the water outlet 13 are located on opposite sides of the housing 1 so that the filtered water can be discharged through the water outlet 13.

[0037] The position of the water inlet 12 is higher than the position of the water outlet 13, that is, the water inlet 12 is located at the top of the shell 1, and the water outlet 13 is located at the bottom of the shell 1. The water to be filtered and purified enters the cavity 11 through the water inlet 12 at the top of the shell 1, and is discharged through the water outlet 13 at the bottom. Filtering and purifying through the top-down filtering structure can not only improve the efficiency of filtering and purification, but also reduce the clogging problem caused by excessive local impurities in the cleaning component 2. Moreover, the filtered and purified water can flow to the water outlet 13 and be discharged from the cavity 11 without external power, effectively reducing energy consumption.

[0038] Of course, in the embodiment of the present application, the water inlet 12 and the water outlet 13 are not limited to the above structure, and those skilled in the art can set them according to actual needs. For example, the water inlet 12 can be set at the top of the side surface of the housing 1, and the water outlet 13 can be set at the bottom of the side surface of the housing 1.

[0039] like Figure 1 and Figure 3 As shown, the cleaning component 2 is disposed in the cavity 11, and the water inlet 12 and the water outlet 13 are located on opposite sides of the cleaning component 2. That is, the water to be filtered and purified enters the cavity 11 through the water inlet 12, is filtered and purified by the cleaning component 2 in the cavity 11, and the filtered and purified water is discharged through the water outlet 13.

[0040] The filter part 21 of the cleaning component 2 is used to filter impurities in the water, and the purification part 22 of the cleaning component 2 is used to decompose some impurities in the filtered water. The filtered and purified water is discharged through the drain outlet.

[0041] like Figure 1 and Figure 3 As shown, the filter unit 21 is disposed in the cavity 11 , and the interior of the housing 1 is divided into two chambers, namely a first chamber 111 and a second chamber 112 , by the filter unit 21 .

[0042] The first chamber 111 is connected to the water inlet 12 to perform preliminary filtration on the water to be filtered. The water after preliminary filtration enters the second chamber 112. The second chamber 112 is connected to the water outlet 13.

[0043] The water after the preliminary filtration is decomposed and purified in the second chamber 112 by the purification unit 22. The purified water is discharged from the second chamber 112 through the water outlet 13.

[0044] Of course, in the embodiment of the present application, the filter is not limited to the above-mentioned scenes, and those skilled in the art can set it according to actual needs. For example, the filter is also applicable to scenes such as turtle ponds and crab ponds.

[0045] A water quality detection device is provided on the housing 1. The detection device detects the quality of water at the water outlet 13. When the water quality detected by the detection device meets the set standard, the water outlet pipe is opened, and the filtered and purified water in the cavity 11 is discharged through the water outlet pipe.

[0046] One end of the return pipe is connected to the end of the housing 1 near the water inlet pipe, and the other end of the return pipe is connected to the end of the housing 1 near the water outlet pipe. When the detection device detects that the water quality at the water outlet pipe does not meet the set standard, the water outlet pipe is in a closed state, and the return pipe draws the filtered and purified water to the end of the housing 1 near the water inlet pipe, and returns the filtered and purified water to the first chamber 111 to be filtered and purified again. The detection device and the return pipe are set to detect the filtering and purification quality of water.

[0047] In the embodiment of the present application, the water entering the cavity 11 is initially filtered by the filter unit 21, and the impurities in the water after the initial filtration are decomposed and purified by the purification unit 22, thereby effectively improving the clean quality of the filtered water. By setting a detection device, the quality of the filtered and purified water can be detected. If it meets the set standard, it can be discharged. If it does not meet the set standard, it is repeatedly filtered and purified through the reflux pipe, thereby effectively improving the filtration and purification quality of the water.

[0048] In addition, the water in the fish tank or fish pond is filtered and purified through a top-down filtering structure, which not only allows the filtered and purified water to flow to the water outlet 13 and be discharged from the cavity 11 without external power, effectively reducing energy consumption, but also can reduce the blockage problem caused by excessive local impurities in the cleaning component 2.

[0049] In one example, the filter unit 21 includes a first filter plate 211 , which is disposed in the cavity 11 , close to the water inlet 12 , and a first chamber 111 is formed between the water inlet 12 of the housing 1 and the first filter plate 211 .

[0050] like Figure 1 and Figure 3 As shown, the filter unit 21 includes a first filter plate 211, which is in a rectangular plate shape. The first filter plate 211 is a filter cotton. The first filter plate 211 is arranged in the cavity 11, and the first filter plate 211 is arranged on one side of the cavity 11 close to the water inlet 12.

[0051] Of course, in the embodiment of the present application, the first filter plate 211 is not limited to the above materials, and those skilled in the art can configure it according to actual needs.

[0052] The first filter plate 211 is inside the housing 1 , and separates the cavity 11 into a first chamber 111 . The first chamber 111 is communicated with the water inlet 12 .

[0053] That is, the water to be filtered and purified in the fish pond or fish tank enters the cavity 11 through the water inlet 12. The water to be filtered and purified enters the first chamber 111 through the water inlet 12, and is preliminarily filtered by the first filter plate 211 in the first chamber 111, and the impurities such as larger particles in the water to be filtered and purified are preliminarily filtered.

[0054] By setting up a first filter plate to perform preliminary filtration on the water that needs to be filtered and purified, clogging caused by impurities such as larger particles or poor purification effect in the subsequent purification process can be reduced. By performing preliminary filtration on the water that needs to be filtered and purified, the purification efficiency can be effectively improved.

[0055] In addition, by setting the water inlet 12 above the first filter plate 211, the water to be filtered and purified flows through the first filter plate 211 from top to bottom. Not only does it not require external power to make the filtered water flow through the first filter plate 211 to reduce energy consumption, it can also reduce the blockage problem caused by excessive local impurities in the first filter plate 211.

[0056] In one example, the filter unit 21 also includes a second filter plate 212, which is disposed in the cavity 11, close to the water outlet 13, and a second chamber 112 is provided between the first filter plate 211 and the second filter plate 212 of the shell 1; wherein the purification unit 22 is disposed between the first filter plate 211 and the second filter plate 212.

[0057] like Figure 1 and Figure 3 As shown, the filter unit 21 further includes a second filter plate 212, which is in a rectangular plate shape. The second filter plate 212 is filter cotton. The second filter plate 212 is arranged in the cavity 11, and the second filter plate 212 is arranged on one side of the cavity 11 close to the water outlet 13.

[0058] That is, the second filter plate 212 is located below the first filter plate 211. The water to be filtered and purified enters the first chamber 111 through the water inlet 12, flows through the first filter plate 211 for preliminary filtration, and the water after preliminary filtration is filtered again through the second filter plate 212. The water to be filtered and purified is filtered multiple times to filter out impurities in the water, effectively improving the clean quality of the water.

[0059] Of course, in the embodiment of the present application, the second filter plate 212 is not limited to the above materials, and those skilled in the art can configure it according to actual needs.

[0060] The housing 1 is provided with a first filter plate 211 and a second filter plate 212, wherein the first filter plate 211 is close to the water inlet 12, and the second filter plate 212 is close to the water outlet 13. The cavity 11 between the water inlet 12 and the first filter plate 211 is a first chamber 111, and the cavity 11 between the first filter plate 211 and the second filter plate 212 is a second chamber 112. The purification unit 22 is provided in the second chamber 112.

[0061] That is, the water to be filtered and purified in the fish pond or fish tank enters the first chamber 111 through the water inlet 12 and is preliminarily filtered through the first filter plate 211. The preliminarily filtered water enters the second chamber 112, and the purification unit 22 in the second chamber 112 purifies the preliminarily filtered water, for example, the impurities in the preliminarily filtered water are decomposed by the purification unit 22. The purified water is filtered through the second filter plate 212, and the undecomposed or indecomposable fine impurities are filtered again through the second filter plate 212, and the re-filtered water is discharged through the water outlet 13.

[0062] The water to be filtered and purified is initially filtered through the first filter plate 211 to filter out impurities such as larger particles in the water. The water that has passed the initial filtration is decomposed and purified through the purification unit 22. The decomposed and purified water is filtered again through the second filter plate 212 to filter out fine impurities in the decomposed and purified water, thereby effectively improving the filtering and purification effect. Furthermore, through the top-down filtering structure, it is possible to effectively prevent impurities in the water from accumulating locally in the cleaning component 2 and causing blockage.

[0063] In one example, a first drip hole 2111 is disposed on the first filter plate 211 , and a second drip hole 2121 is disposed on the second filter plate 212 . The diameter of the first drip hole 2111 is greater than the diameter of the second drip hole 2121 .

[0064] like Figures 1 to 3 As shown, the first filter plate 211 is in the shape of a rectangular plate. A plurality of first drip holes 2111 are provided on the first filter plate 211. The plurality of first drip holes 2111 are distributed in a rectangular array. The first drip holes 2111 are circular through holes. The diameter of the first drip holes 2111 is 194 mm. The first drip holes 2111 are provided to filter impurities such as larger particles in the water.

[0065] Of course, in the embodiment of the present application, the first filter plate 211 and the first drip hole 2111 are not limited to the above-mentioned size and structure, and those skilled in the art can set them according to actual needs. For example, the first filter plate 211 can also be a square plate structure or a circular plate structure. The multiple first drip holes 2111 can also be distributed in a ring array. The first drip hole 2111 can also be a rectangular through hole, a polygonal through hole, or an elliptical through hole, etc.

[0066] like Figures 1 to 3As shown, the second filter plate 212 is in the shape of a rectangular plate. A plurality of second drip holes 2121 are provided on the second filter plate 212. The plurality of second drip holes 2121 are distributed in a rectangular array. The second drip holes 2121 are circular through holes. The diameter of the second drip holes 2121 is 108 mm. The second drip holes 2121 are provided to filter impurities such as fine particles in the water during the second filtration.

[0067] Of course, in the embodiment of the present application, the second filter plate 212 and the second drip hole 2121 are not limited to the above-mentioned size and structure, and those skilled in the art can set them according to actual needs. For example, the second filter plate 212 can also be a square plate structure or a circular plate structure. The plurality of second drip holes 2121 can also be distributed in a ring array. The second drip hole 2121 can also be a rectangular through hole, a polygonal through hole, or an elliptical through hole, etc.

[0068] The first filter plate 211 is used for preliminary filtration, and the second filter plate 212 is used for secondary filtration. There are many impurities in the water during the initial filtration, and impurities such as larger particles need to be intercepted. Therefore, the size of the first drip hole 2111 is designed to be larger than the diameter of the second drip hole 2121, so as to intercept larger impurities such as particles, and allow water with smaller impurities such as particles to enter the second chamber 112 for decomposition and purification. When filtering again, there are mostly smaller impurities such as particles in the water, so the size of the second drip hole 2121 is designed to be smaller than the diameter of the first drip hole 2111, so as to intercept smaller impurities such as particles, and effectively improve the filtration quality of water.

[0069] In one example, the housing 1 is provided with an opening 14 , the opening 14 is communicated with the cavity 11 , and the position of the opening 14 corresponds to the position of the purification unit 22 .

[0070] like Figure 3 to Figure 4 As shown, the front side of the housing 1 is provided with an opening 14. The opening 14 is rectangular. The position of the opening 14 corresponds to the position of the purification unit 22, and the purification unit 22 can be pushed into the cavity 11 or taken out through the opening 14 to clean or replace the purification unit 22. By providing the opening 14, it is convenient to clean, replace or overhaul the purification unit 22, effectively improving the purification quality and reducing the maintenance cost.

[0071] In one example, the purification unit 22 includes a support frame 221 and a purification member 222 . The support frame 221 is disposed on the inner wall of the housing 1 , and the purification member 222 is disposed on the support frame 221 . The support frame 221 corresponds to the position of the opening 14 .

[0072] like Figure 1 and Figure 3As shown, the purification part 22 includes a support frame 221. The support frame 221 is used to carry a purification member 222, so that the purification member 222 is located in the second chamber 112, and the water after the preliminary filtration is purified by the purification member 222. The purification member 222 includes but is not limited to biomass.

[0073] In one example, at least two support brackets 221 are disposed in the second chamber 112 . The two support brackets 221 are disposed opposite to each other on the inner wall of the housing 1 . The purification member 222 can slide relative to the support brackets 221 .

[0074] like Figure 1 and Figure 3 As shown, the support frame 221 is a right-angled triangular prism. A support frame 221 is provided on the corresponding inner walls of the housing 1 on both sides. The two support frames 221 are provided correspondingly. The opposite ends of the purifier 222 are respectively overlapped on the support frames 221, and the purifier 222 is carried by the two support frames 221, so that the water after preliminary filtration flows to the purifier 222, and the impurities in the water are decomposed and purified by the purifier 222, and the purified water flows to the bottom of the cavity 11 in the housing 1.

[0075] Of course, in the embodiment of the present application, the support frame 221 is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the support frame 221 can also be a rectangular frame, the lower edge of the purification element 222 is overlapped on the support frame 221, and the middle part of the support frame 221 is hollowed out so that the purified water flows to the bottom of the cavity 11.

[0076] In one example, the purification unit 22 further includes a carrier 223 , which is movably connected to the support frame 221 . The carrier 223 can extend out of the cavity 11 through the opening 14 , and the purification component 222 is disposed on the carrier 223 .

[0077] like Figure 1 and Figure 3 As shown, the purification unit 22 also includes a carrier 223. The carrier 223 is a rectangular plate-shaped structure with a groove on the top. Two carriers 223 are arranged in the second chamber 112, including a first carrier 223 and a second carrier 223. The first carrier 223 is arranged below the first filter plate 211, the second carrier 223 is arranged below the first carrier 223, and the second carrier 223 is located above the second filter plate 212.

[0078] The length of the first rack 223 is 1050 mm, the width is 690 mm, and the height is 140 mm. The length of the second rack 223 is 1050 mm, the width is 690 mm, and the height is 100 mm. The height of the first rack 223 is greater than the height of the second rack 223 to prevent the water level after preliminary filtration in the first rack 223 from being too high and overflowing, so that the water that has not been preliminary purified flows to the second rack 223.

[0079] A third drip hole is provided on the first carrier 223, and a fourth drip hole is provided on the second carrier 223. The diameter of the third drip hole is greater than the diameter of the fourth drip hole. The purification element 222 on the first carrier 223 can perform preliminary purification on the preliminarily filtered water, and the impurities in the preliminarily purified water are reduced, so that the preliminarily purified water flows through the third drip hole to the purification element 222 of the second carrier 223, and the preliminarily purified water is purified again.

[0080] The diameter of the fourth drip hole is greater than the diameter of the second filter plate 212 .

[0081] Purification components 222 are placed in the grooves of the first and second carriers 223. One side of the first and second carriers 223 is opposite to the opening 14, and the carriers 223 can be pushed into the cavity 11 through the opening 14, or pulled out of the cavity 11 through the opening 14, so as to clean or replace the purification components 222 in the grooves.

[0082] In one example, the opening 14 includes a first opening 141 and a second opening 142, and at least two purification parts 22 are arranged in the second chamber 112, wherein one purification part 22 is close to the water inlet 12 and can extend out of the second chamber 112 through the first opening 141, and the other purification part 22 is close to the water outlet 13 and can extend out of the second chamber 112 through the second opening 142.

[0083] like Figure 3 and Figure 4 As shown, the front side of the housing 1 is provided with a first opening 141 and a second opening 142. The first opening 141 and the second opening 142 are both rectangular openings 14. The first opening 141 corresponds to the position of the first carrier 223, and the second opening 142 corresponds to the position of the second carrier 223.

[0084] The length dimension of the first opening 141 is 1050 mm, and the height dimension is 140 mm. The length dimension of the second opening 142 is 1050 mm, and the height dimension is 100 mm.

[0085] The first carrier 223 can be taken out of or extended out of the housing 1 through the first opening 141, or can be placed into the cavity 11 through the first opening 141. The second carrier 223 can be taken out of or extended out of the housing 1 through the second opening 142, or can be placed into the cavity 11 through the second opening 142. The opening 14 matching the carrier 223 is provided so that the purification element 222 at the corresponding position can be cleaned or replaced separately.

[0086] Of course, in the embodiment of the present application, the opening 14 is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, only one opening 14 is provided, and the opening 14 corresponds to the position of the first carrier 223 and the second carrier 223. Alternatively, multiple carriers 223 are provided, and the housing 1 is provided with openings 14 matching the number of carriers 223.
