[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a backflow prevention filter device for an electronic injector booster, comprising a cylinder 4, a top cover 1, and a bottom cover 5. Both the top cover 1 and the bottom cover 5 have threaded grooves 16 on their surfaces. The upper and lower ends of the cylinder 4 are threadedly connected to the top cover 1 and the bottom cover 5, respectively. An adjusting rod 7 is rotatably connected to the center of the bottom cover 5. The adjusting rod 7 is sealed to the bottom cover 5. The adjusting rod 7 is hollow to prevent gas and liquid from flowing out. The upper end of the adjusting rod 7 extends into the interior of the cylinder 4 and is connected to a fixing frame 10. An inner filter cylinder 11 is installed in the center of the top surface of the fixing frame 10. The inner filter cylinder 11 performs initial filtration and concentration of impurities. Most impurities are concentrated inside the inner filter cylinder 11. Several cleaning rods 12 are vertically installed at equal intervals on the top edge of the fixing frame 10. Scrapers 13 are installed on the outer wall of the cleaning rods 12, and the side wall of the scraper 13 is in close contact with the inner wall of the cylinder 4. Rotating the fixing frame 10 can drive the cleaning rods 12. During the rotation, the cleaning rods 12 can clean the inner wall of the filter through the scraper 13. Connecting pipes 3 are fixed on the two side walls of the top cover 1 respectively. The surface of the connecting pipe 3 is integrally formed with an anti-detachment ring 2. After the air pipe is connected to the connecting pipe 3, the anti-detachment ring 2 can achieve a certain anti-detachment effect and improve the stability of the connection.

[0022] Further improvements include an external nozzle 14 installed on the upper end of the outer wall of the cleaning rod 12, and four internal nozzles 15 evenly distributed on the inner wall of the cleaning rod 12. The external nozzles 14 face the inner wall of the filter, and the internal nozzles 15 face the inner filter cartridge 11.

[0023] Further improvements include the installation of four anti-backflow rings 18 on the inner wall of the inner filter cartridge 11. The four anti-backflow rings 18 are equidistantly distributed and correspond to the positions of the inner nozzles 15. The anti-backflow rings 18 have a tapering structure from top to bottom. The anti-backflow rings 18 can retain impurities inside the inner filter cartridge 11 and prevent impurities from flowing back upward.

[0024] Further improvements include the installation of a filter disc 17 on the surface of the adjusting rod 7 and between the fixing frame 10 and the bottom cover 5. The filter disc 17 performs secondary filtration of the liquid inside the filter.

[0025] Further improvements include symmetrical drainage holes at the bottom of the bottom cover 5, with a cap 9 embedded inside each drainage hole. After opening the cap 9, wastewater can be discharged through the drainage hole.

[0026] Further improvements include an adjustment plate 6 installed at the lower end of the adjustment rod 7, with a connector 8 located in the center of the bottom surface of the adjustment plate 6. The connector 8 is a one-way connector and is internally connected to the cleaning rod 12 via the adjustment rod 7. The connector 8 is connected to an external water pipe, and after connection, cleaning water can be introduced into the interior and sprayed out through the inner nozzle 15 and the outer nozzle 14.

[0027] Working principle: The filter is filled with filtrate. A gas guide hose is installed on the connecting pipe 3 on one side of the filter. The gas guide hose is then installed on the air inlet of the water purifier. After the water purifier is started, external gas enters the filter and is filtered. Impurities remain in the inner filter cylinder 11 inside the filter. After use, the adjusting plate 6 can be rotated, and the adjusting rod 7 can be used to rotate the fixing frame 10. After the fixing frame 10 rotates, the inner wall of the filter is cleaned by the scraper 13. During the cleaning process, the filter is gently shaken, and the impurities can be carried down from the inner wall of the filter by the internal liquid. After opening the cap 9, the waste liquid can be discharged. When fine cleaning is required, the connector 8 is connected to the external water pipe, and the cleaning water is sprayed out through the inner nozzle 15 and the outer nozzle 14. After rotating the fixing frame 10, the inside of the filter is rinsed. After removing the bottom cover 5, the fixing frame 10 is taken out and the inner filter cylinder 11 and filter plate 17 are rinsed to flush out the internal impurities. After that, it can be reinstalled.

[0028] The components of this utility model are: 1. Top cover; 2. Anti-detachment ring; 3. Connecting pipe; 4. Cylinder; 5. Bottom cover; 6. Adjusting disc; 7. Adjusting rod; 8. Connector; 9. Sealing cap; 10. Fixing frame; 11. Inner filter cylinder; 12. Cleaning rod; 13. Scraper; 14. Outer nozzle; 15. Inner nozzle; 16. Threaded groove; 17. Filter disc; 18. Anti-reverse ring. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing water-light machine air filters contain impurities after air filtration, making it inconvenient to clean the inside of the filter. The problem of impurities accumulating inside the filter and affecting the negative pressure during cleaning is addressed by the present invention. This invention incorporates a cleaning assembly consisting of a fixing frame 10, an inner filter cylinder 11, and a cleaning rod 12 inside the filter. During use, the inner filter cylinder 11 filters impurities. After use, rotating the adjusting disc 6 drives the cleaning rod 12, which cleans the inner wall of the filter. The external water pipe connected to the connector 8 further cleans the inner wall of the filter, washing away impurities adhering to the filter inner wall and allowing them to fall into the filter disc 17. This facilitates centralized processing of impurities and reduces the number of times the filter needs to be disassembled for cleaning.
