[0025] The specific details of this utility model are further described below:

[0026] This utility model relates to a fish tank water filtration system, which includes a fish tank 1, a water pump, pipes and a filter element, to achieve water filtration in the fish tank.

[0027] This utility model is as follows Figure 1 The main water intake pipe 3 is connected to the fish tank 1. The main water intake pipe 3 is divided into a filter main pipe 4 and a flushing main pipe 5 through a T-junction. The filter main pipe 4 and the flushing main pipe 5 are respectively connected to the T-junction, and the second pipe opening of the two T-junctions is connected through a power pipe 6. A water pump is installed on the power pipe 6. The water pump is a bidirectional water pump.

[0028] The third port of the tee connected to the main filter pipe is connected to the filter branch pipe 7. Multiple water distribution tee pipes 8 are connected in series on the filter branch pipe 7. The third port of the tee connected to the main flushing pipe 5 is connected to the flushing branch pipe 9. Multiple flushing tee pipes 10 are connected in series on the flushing branch pipe 9. The water distribution tee pipes 8 and the flushing tee pipes 10 are connected to the filter cylinder 11, and filter media 19 is installed inside the filter cylinder 11. A drain valve 12 is installed at the end of the filter branch pipe 7. The drain valve 12 is connected to the external drain. The end of the flushing branch pipe 9 is connected to the fish tank 1.

[0029] A filter one-way valve 13 and a flushing one-way valve 14 are installed on the filter main pipe 4 and the flushing main pipe 5. A filter branch pipe one-way valve 15 is installed before the water distribution tee 8 on the filter branch pipe 7. A flushing branch pipe one-way valve 16 is installed before the flushing tee 10 on the flushing branch pipe 9.

[0030] The filter one-way valve 13 and the flushing one-way valve 14 control the water flow direction to flow unidirectionally from the main pumping pipe to the power pipe 6; the filter branch one-way valve 15 and the flushing branch one-way valve 16 control the water flow direction to flow from the power pipe to the three-way connection of the filter cartridge 11.

[0031] The flow direction of water during the filtration and rinsing process is explained based on the above structure:

[0032] During the filtration stage, the bidirectional water pump is activated to draw water towards the filtration direction. The fish tank water flows from the aquarium through the main filtration pipe and the one-way valve 13 into the power pipe 6. After being pressurized by the bidirectional water pump, it enters the filtration branch pipe. At the water distribution tee 8 position, the fish tank water is circulated into multiple filter cartridges 11. After being filtered by the filter cartridges 11, the fish tank water flows through the flushing tee 10 and into the flushing branch pipe. The end of the flushing branch pipe 9 connects to the aquarium 1, allowing the filtered water to flow into the aquarium. During this stage, when the fish tank water is at the tee position at the rear end of the flushing main pipe 5, the one-way valve 14 on the flushing main pipe 5 prevents the fish tank water from flowing back into the main filtration pipe.

[0033] After passing through the filter cartridge, the fish tank water is prevented from flowing back into the main filter pipe and power pipe by the one-way valve 16 on the flushing branch pipe.

[0034] Meanwhile, during this stage, because the flushing manifold is connected to the aquarium at a high position, more water generated by the bidirectional water pump enters the filter canister, and fewer fish flow into the aquarium through the flushing manifold, thus maintaining the filtration process.

[0035] During the rinsing stage, the bidirectional water pump is turned on to pump water in the rinsing direction. The fish tank water enters the power pipe 6 from the fish tank through the rinsing main pipe and the rinsing one-way valve 14. After being pressurized by the bidirectional water pump, it enters the filter branch pipe. At the rinsing tee 10 position, the fish tank water is passed into multiple filter cartridges 11. The fish tank water backwashes the filter media of the filter cartridges 11. Impurities and microparticles flow into the rinsing branch pipe through the rinsing tee 10. The drain valve at the end of the rinsing branch pipe 9 is opened to discharge the rinsing water.

[0036] During this stage, when the fish tank water is at the three-way position at the back end of the filter main pipe, the fish tank water cannot flow back into the water pumping main pipe due to the filter check valve 14 on the filter main pipe.

[0037] After passing through the filter cartridge, the fish tank water is prevented from flowing back into the main flushing pipe and power pipe by the one-way valve on the filter manifold.

[0038] To improve the filtration effect, the filter cylinder 11 of this device is provided with a single-opening filter cylinder 17. The single-opening filter cylinder 17 is made of sintered porous material. The single-opening filter cylinder 17 is cylindrical with an opening on one side, and the opening side faces the direction of the incoming water during filtration. The bottom of the single-opening filter cylinder 17 contacts the end hole of the filter cylinder 11.

[0039] The filter media 19 is composed of sand-like particles, and the single-opening filter cartridge 17 is made by sintering a mixture of sand, black clay powder, dextrin, cellulose, clay, feldspar, and glass powder. The filter media is replaceable and can be rinsed with water for reuse.

[0040] When in use, the filter media captures large particles, while the single-opening filter cartridge 17 captures small particles, thus achieving clean filtration of the water for fishkeeping.

[0041] The filter cylinder 11 of this device is a hollow cylinder with removable caps 18 at both ends. The caps 18 have an opening in the middle that connects to the flushing tee 10 or the filter tee.

[0042] The filter cartridge has caps at both ends, one purpose of which is to connect it to the pipeline, and the other is for adding and removing filter material.

[0043] Specifically, the bottom of the fish tank 1 is provided with a filter outlet 20, and the bottom or side of the fish tank 1 is provided with a filter return hole 21. The main water supply pipe 3 is connected to the filter outlet 20, and the end of the flushing branch pipe 9 is connected to the filter return hole 21.

[0044] The end of the flushing pipe 9 leads into the bottom of the fish tank 1, and a fish-proof filter screen is installed at the inlet. The filter outlet 20 has an outlet filter screen on the inside side of the fish tank 1.

[0045] Both fish-proof filters and water outlet filters have the function of preventing fish from entering, and are made using plastic mesh or stainless steel metal mesh.

[0046] The bidirectional water pump used in this device is a purchased component. It is a GHP series bidirectional pump from Shenzhen Youpeng Technology Co., Ltd. The pump's forward rotation is controlled by circuitry to control the water supply direction for either filtration or rinsing.
