[0002] The backwashing device in a self-cleaning aquarium filter is used to clean the filter media and is the core component that enables the filter to self-clean. Self-cleaning aquarium filters achieve continuous cleaning of the filter media through the backwashing device, reducing the frequency of manual maintenance and maintaining stable water quality. The backwashing device used in a self-cleaning aquarium filter mainly consists of a backwash pump, pipes, and a drain structure. Activating the backwash pump allows water to enter from the outlet of the aquarium filter to flush the filter media, and the drain structure then removes the waste.

[0003] When using existing backwashing devices, the entire device is installed on the aquarium filter. The structure for discharging waste is fixed in position after installation and cannot be adjusted relative to other parts. It is difficult to adjust the installation according to the actual situation. At the same time, the waste discharge structure does not have a separate opening part, which makes it inconvenient to discharge waste and clean it. The waste discharge process is time-consuming and laborious, and its flexibility and adaptability are generally poor. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, a backwashing device for a self-cleaning aquarium filter includes a backwash pump 1, an inlet connector 2 and a drain connector 3. A first flexible tube 4 is connected to the inlet connector 2, and a drain structure 5 is connected to the end of the first flexible tube 4. A second flexible tube 6 is provided on the drain structure 5. Both the first and second flexible tubes 4 and 6 can be deformed and bent, facilitating the connection of related joints and providing high flexibility in use. A base plate 8 is provided at the lower end of the backwash pump 1, and mounting holes are provided on the base plate 8. Mounting heads are provided at both ends of the first flexible tube 4, and the first flexible tube 4 is connected to the inlet connector 2 and the drain structure 5 through the mounting heads. The end of the second flexible tube 6 is connected to the filter cartridge in the aquarium filter, and a drain pipe 7 is installed on the drain connector 3.

[0021] When installing the backwashing device, screws are used to pass through the mounting holes to set the base plate 8 onto the main body of the aquarium filter, thereby fixing the backwashing pump 1. The two ends of the first plastic tube 4 are connected to the water inlet connector 2 and the drain structure 5 respectively using the mounting head. The drain structure 5 is suspended on the aquarium. A drain pipe 7 is installed on the drain connector 3, and the end of the drain pipe 7 is located in the aquarium. The two ends of the second plastic tube 6 are connected to the filter cartridge of the aquarium filter and the drain structure 5 respectively, thus completing the installation of the entire backwashing device.

[0022] During use, the water pump on the aquarium filter stops running, and the backwash pump 1 starts running to create a suction effect. Under the suction effect, the water outlet pipe of the aquarium filter draws water, and the water flows in reverse in the filter cylinder to achieve the backwashing effect. After the impurities are washed down, they enter the second plastic tube 6 along with the water. Then, they are filtered when passing through the drain structure 5. The impurities remain in the drain structure 5, and the filtered water continues to flow. Finally, it is discharged back into the aquarium from the drain pipe 7, thus completing the backwashing process.

[0023] According to the above implementation scheme, the sewage discharge structure 5 includes a collection pipe 501, a connecting pipe 502, an end 503, a sealing gasket 504, and an installation component 505. The collection pipe 501 and the connecting pipe 502 are fixedly connected. The sealing gasket 504 is disposed inside the end 503, and the end 503 is installed at the lower end of the collection pipe 501. The installation component 505 is disposed on the connecting pipe 502. The sewage discharge structure 5 also includes a connecting hole 506, a filter frame 507, a threaded connector 508, and a filter screen 509. The connecting hole 506 is disposed on the connecting pipe 502. The filter frame 507 and the threaded connector 508 are fixedly connected, and the threaded connector 508 is threaded into the connecting hole 506. The filter screen 509 is fixed on the filter frame 507.

[0024] Through the set sewage discharge structure 5, a connecting pipe 502 is set on the collection pipe 501. One of the connecting pipes 502 is connected to a filter frame 507, which forms a filter during the backwashing process, ensuring that the backwash water enters the aquarium cleanly and ensuring the cleanliness of the aquarium. An end cap 503 is installed at the lower end of the collection pipe 501, which can be quickly opened for sewage discharge and cleaning. At the same time, the end cap 503 is used in conjunction with the sealing gasket 504 after installation, which has good sealing performance and does not affect the normal circulation of water during backwashing. The filter frame 507 is installed on the connecting pipe 502 with a threaded connector 508, which can be quickly disassembled and replaced.

[0025] During the installation of the drainage structure 5, the installation component 505 is adjusted to suspend the collection pipe 501 and the connecting pipe 502. The first plastic pipe 4 and the second plastic pipe 6 are connected to the two connecting pipes 502 respectively, thus completing the installation of the drainage structure 5. In use, water passes through the filter cartridge in the aquarium filter, backwashing the filter media. Wastewater containing impurities enters the collection pipe 501 through the connecting pipe 502. After being filtered by the filter screen 509 on the filter frame 507, the impurities remain in the collection pipe 501. The filtered water then enters the first plastic pipe 4 through the connecting pipe 502 and is finally discharged into the aquarium.

[0026] When backwashing is complete and impurities need to be removed, simply disassemble end 503 to clean them. The structure is simple and the operation is convenient and quick. If it is necessary to replace the filter screen 509 on the filter frame 507, rotate the filter frame 507, unscrew the threaded connector 508 from the connection hole 506, and then remove the filter frame 507 to perform the relevant operations.

[0027] The mounting assembly 505 includes a fixing bracket 5051, a suspension bracket 5052, a connecting rod 5053, and a clamping screw 5054. The fixing bracket 5051 is mounted on the connecting pipe 502. The suspension bracket 5052 and the connecting rod 5053 are fixedly connected, and the connecting rod 5053 passes through the fixing bracket 5051. The clamping screw 5054 is threaded onto the fixing bracket 5051, and the end of the clamping screw 5054 abuts against the connecting rod 5053. The mounting assembly 505 is used for the suspension installation of the sewage structure 5, which allows for quick assembly and disassembly, and the installation position can be adjusted according to the actual situation, making it highly flexible and adaptable.

[0028] When installing the drainage structure 5 using the installation component 505, loosen the clamping screw 5054 on the fixing bracket 5051, move the connecting rod 5053 to adjust the position of the suspension bracket 5052, fix the connecting rod 5053 with the clamping screw 5054 after adjustment, and then use the suspension bracket 5052 to suspend and install the drainage structure 5 on the aquarium for use.

[0029] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
