[0017] 2. By incorporating an anti-clogging cleaning component, the electronically controlled rotating shaft drives the cleaning rod to clean the filter screen, preventing clogging after prolonged use and ensuring filtration efficiency. Simultaneously, the baffle plate normally blocks the flow from the cleaning port. During cleaning, the baffle plate rotates with the rotating disc, opening the cleaning port. As the cleaning rod sweeps, impurities are swept upwards and fall from the cleaning port into the rotating disc, where they are flushed away with the cleaning wastewater, improving the cleaning effect on the filter screen.

[0018] In summary, this application, through the design of a self-cleaning filtration mechanism and an anti-clogging cleaning component, allows for backwashing of the filter screen after use. Simultaneously, a cleaning rod removes impurities from the filter screen, ensuring its cleanliness over extended use and maintaining optimal water filtration.

[0027] Please refer to Figures 1-5 As shown in the figure, a water purifier filtering device, including device main body 1 and self-cleaning filtering mechanism 2, the inner side of device main body 1 is provided with self-cleaning filtering mechanism 2;

[0028] Self-cleaning filtering mechanism 2 includes filtering assembly 21 installed in the inner side of device main body 1, the lower side of filtering assembly 21 is installed with cleaning assembly 22, the outer side of cleaning assembly 22 is installed with drainage assembly 23.

[0029] In the embodiment, filtering assembly 21 includes filtering connecting plate 211 installed in the inner side of device main body 1, the inner side of filtering connecting plate 211 is installed with filter screen 212, through multiple filter screens 212, multi-stage filtration is carried out, and the filtration effect on water is improved.

[0030] In the embodiment, cleaning assembly 22 includes waterproof motor 221 installed in the inner side of filtering connecting plate 211, the bottom end of waterproof motor 221 is installed with rotating disc 222, rotating disc 222 is attached between the bottom surface of filtering connecting plate 211, through the operation of waterproof motor 221, rotating disc 222 is driven to rotate at the lower end of filtering connecting plate 211, so that the gap on rotating disc 222 corresponds to filter screen 212, ensuring the normal use of filter screen 212, then when filter screen 212 needs to be cleaned, rotating disc 222 is rotated again, so that the gap on rotating disc 222 is placed at the bottom end of filtering connecting plate 211, preventing sewage generated during cleaning from flowing into the water purifier.

[0031] In the embodiment, the outer side of the device body 1 is provided with an external water pipe 223, the bottom end of the rotating disc 222 is provided with a cleaning water pipe 224, and the inner side of the rotating disc 222 is provided with a cleaning spray head 225. External clean water is introduced into the cleaning water pipe 224 through the external water pipe 223, and the filter screen 212 is back-flushed through the cleaning spray head 225 to ensure the cleanliness of the filter screen 212.

[0032] In the embodiment, the drainage assembly 23 includes a drainage port 231 provided on the outer side of the rotating disc 222, and the external water pipe 223 is provided with a drainage pipe 232. The drainage port 231 is connected to the external water pipe 223 when the rotating disc 222 rotates for cleaning, and the sewage generated during cleaning falls into the rotating disc 222 and then flows into the external water pipe 223 through the drainage pipe 232, so as to be discharged from the device and avoid secondary pollution of the water that needs to be filtered subsequently.

[0033] In some embodiments, the top end of the filter connecting plate 211 is provided with a blockage prevention and cleaning assembly 3. The blockage prevention and cleaning assembly 3 includes an electric control rotating shaft 31 installed at the top end of the filter connecting plate 211, and a cleaning rod 32 fixedly connected to the outer side of the electric control rotating shaft 31. The cleaning rod 32 is in an outwardly curved structure, and the filter screen 212 is cleaned by the electric control rotating shaft 31 driving the cleaning rod 32, so as to prevent the filter screen 212 from being blocked after long-term use and ensure the filtering effect.

[0034] In some embodiments, a cleaning port 33 is provided on the surface of the outer side of the filter connecting plate 211, and a blocking plate 34 is installed on the inner side of the rotating disc 222. The blocking plate 34 corresponds to the cleaning port 33 one by one. The blocking plate 34 blocks the lower side of the cleaning port 33 during normal use to prevent the flow of the cleaning port 33. During cleaning, the blocking plate 34 rotates with the rotating disc 222 to open the cleaning port 33. When the cleaning rod 32 cleans, the impurities are swept towards the cleaning port 33 and fall into the rotating disc 222, and are washed away with the sewage, thereby improving the cleaning effect of the filter screen 212.

[0035] As can be seen from the above technical solution, in use, the device is first installed at the desired location. Then, multiple sets of filter screens 212 perform multi-stage filtration to improve the water filtration effect. Next, the operation of the waterproof motor 221 drives the rotating disk 222 to rotate at the lower end of the filter connecting plate 211, aligning the gap on the rotating disk 222 with the filter screens 212 to ensure normal operation. When cleaning the filter screens 212 is required, the rotating disk 222 rotates again, positioning the gap on the rotating disk 222 at the bottom of the filter connecting plate 211 to prevent wastewater generated during cleaning from flowing into the water purifier. Then, external clean water is introduced into the cleaning water pipe 224 through the external water pipe 223, and the filter screens 212 are backwashed through the cleaning nozzle 225 to ensure their cleanliness. Simultaneously, the rotating disk 222 is cleaned while the filter screens are rotating. Meanwhile, the drain outlet 231 connects to the external water pipe 223, and the cleaning wastewater falls into the rotating disc 222. It then flows into the external water pipe 223 through the drain outlet 232, thus being discharged from the device and preventing secondary pollution to the water that needs to be filtered later. Afterwards, the cleaning rod 32 is driven by the electrically controlled rotating shaft 31 to clean the filter screen 212, preventing the filter screen 212 from becoming clogged after long-term use and ensuring the filtration effect. At the same time, the baffle plate 34 blocks the bottom of the cleaning port 33 during normal use to prevent it from flowing out of the cleaning port 33. During cleaning, the baffle plate 34 rotates with the rotating disc 222, opening the cleaning port 33. When the cleaning rod 32 cleans, it sweeps the impurities towards the cleaning port 33, causing them to fall into the rotating disc 222 and be washed away with the cleaning wastewater, improving the cleaning effect on the filter screen 212. This completes the use of a water purifier filtration device.
