[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1 - Figure 5 As shown, a flushing device for a water purifier mainly includes a mounting frame 1, a filter cartridge 2, a cartridge cover 3, a water inlet 4, a water outlet 5 and a filter element 13. The cartridge cover 3 is fixed to the mounting frame 1 by fastening bolts 12, and the filter cartridge 2 is installed at the lower end of the cartridge cover 3. The filter element 13 is cleverly connected to the filter cartridge 2 to achieve the water purification function. Multiple cartridge covers 3 are interconnected by pipes to ensure the continuity of the entire system. The outermost cartridge cover 3 is provided with a water outlet 5, and the innermost cartridge cover 3 is also provided with a water outlet 5, so that effective water purification operation can be performed through the filter element 13.
[0025] A backwash inlet pipe 6 is connected to the lower end of each filter cartridge 2 to ensure thorough backwashing of the filter cartridges 2 and filter element 13. A backwash drain pipe 10 is installed on the sidewall of the corresponding cartridge cover 3 to drain waste liquid generated during the backwash process. The lower end of the backwash inlet pipe 6 is connected to a first connecting pipe 7, which in turn is connected to a docking pipe 8, which in turn is connected to a water pump 9. The water pump 9 provides the necessary water pressure to backwash the filter cartridges 2 and filter element 13.
[0026] The outer end of the backwash drain pipe 10 is connected to a second connecting pipe 11, ensuring that the backwash waste liquid can be smoothly discharged from the backwash drain pipe 10 and the second connecting pipe 11. The upper end of the cylinder cover 3 is designed as a mounting seat, and the upper end of the mounting seat is provided with multiple mounting holes. The mounting frame 1 is provided with circular holes that are compatible with these mounting holes. The fastening bolts 12 pass through the circular holes of the mounting frame 1 and are inserted into the mounting holes, thereby firmly connecting the cylinder cover 3 to the mounting frame 1. To ensure the sealing of the connection, a rubber ring is specially designed at the connection between the cylinder cover 3 and the mounting frame 1.
[0027] The filter cartridge 2 is connected to the cartridge cover 3 via threads, with a sealing ring installed at the connection to prevent water leakage. The lower end of the filter element 13 is also threadedly connected to the filter cartridge 2, ensuring that the filter element 13 is securely fixed within the filter cartridge 2. The backwash water inlet pipe 6 is integrated with the filter cartridge 2 and faces the filter cartridge 2, ensuring that the backwash water flow directly affects the filter cartridge 2. A filter screen is also installed at the connection between the backwash water inlet pipe 6 and the filter cartridge 2 to prevent impurities from entering the filter cartridge 2.
[0028] The backwash inlet pipe 6 is connected to the first connecting pipe 7 via a flange, bolts, and nuts, ensuring a secure and airtight connection. Similarly, the backwash drain pipe 10 is connected to the second connecting pipe 11 via a flange, bolts, and nuts, ensuring smooth drainage. The second connecting pipe 11 is also connected to the butt-joint pipe 8 via a flange, bolts, and nuts, ensuring stable operation of the entire backwash system.
[0029] To better control the water flow in the backwash inlet pipe 6 and the backwash drain pipe 10, valves are installed on the first connecting pipe 7 and the second connecting pipe 11. These valves can accurately control the timing and intensity of the backwash. The filter element 13 and the cylinder cover 3 adopt a tight design to ensure the sealing of the contact end of the filter element 13 and the cylinder cover 3. The cylinder cover 3 and the filter element 13 are equipped with a sealing ring at the contact end, further ensuring the sealing of the connection. The backwash drain pipe 10 and the cylinder cover 3 are an integrated design, making the entire device more compact and efficient.
[0030] The process is as follows: When the water purifier starts operating, raw water enters the filter cartridge 2 through the water inlet 4. The water then flows through the filter element 13, where impurities are effectively trapped. The purified water then continues along the filter cartridge 2 toward the water outlet 5. Finally, the purified water flows out of the water outlet 5 on the outermost cartridge cover 3 for normal use.
[0031] During the backwash process, when the filter element 13 needs to be cleaned, the water pump 9 needs to be started first, and the water pump 9 will provide the necessary water inlet pressure. Subsequently, the water flow will pass through the first connecting pipe 7 and the docking pipe 8 and enter the backwash water inlet pipe 6. The backwash water inlet pipe 6 will directly act on the filter cartridge 2, so that the water flow enters from the lower end of the filter cartridge 2, thereby realizing the backwashing of the filter element 13. The waste liquid generated during the backwashing process will be discharged through the backwash drain pipe 10 at the lower end of the filter cartridge 2. Then, the waste liquid will pass through the second connecting pipe 11 and finally be discharged out of the system. The entire backwashing process can be controlled by the valves on the first connecting pipe 7 and the second connecting pipe 11 to adjust the timing and intensity of the backwashing. After the backwashing is completed, close the relevant valves and the system can be restored to normal water purification working state.
[0032] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the electric fusion connection adopts the conventional connection method in the existing technology, which will not be described in detail here.
[0033] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
