[0002] A water purifier is a device, generally refers to a small purifier used for home use. Water filters include pre-filters and deep water purifiers. The main function of the pre-filter is to filter out floating objects, mud, red worms, rust and other particulate impurities in tap water to improve the quality of drinking water.

[0003] After the water purifier has been used for a period of time, impurities in the tap water will adhere to the outer surface of the filter element and cause blockage. If it is not cleaned, it will easily cause a decrease in water output. In the self-cleaning structure, the impeller and filter element are driven by the water flow to rotate, and passively contact and clean with the scraper. This method has an unstable cleaning effect, and the flow rate and direction of the water flow need to be accurately calculated, which can easily cause insufficient rotational force of the impeller and filter element, thereby weakening the cleaning effect.

[0004] Therefore, it is necessary to provide a water purifier with an automatic cleaning structure to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0021] like Figure 1-Figure 2 As shown, the utility model provides a water purifier with an automatic cleaning structure, comprising: an operating table 1, a water inlet pipe 2, a water outlet pipe 3, a filter cartridge 4, a filter element 5, a cleaning mechanism 6, and a sewage pipe 7;

[0022] like Figure 1-Figure 2 As shown, a control button is installed on the top surface of the operating table 1 for opening the cleaning structure, and a water inlet pipe 2 and a water outlet pipe 3 are installed on the left and right sides of the interior of the operating table 1 respectively, and a water flow area is formed between the water inlet pipe 2 and the water outlet pipe 3. A three-way valve 21 is installed on the right end of the water inlet pipe 2, a filter cartridge 4 is installed at the bottom of the operating table 1, a filter element 5 is installed on the inner top surface of the filter cartridge 4, and the top of a water pipe 51 of the filter element 5 is located inside the water flow area, a spacing is left between the filter element 5 and the filter cartridge 4, and a cleaning mechanism 6 is arranged between the two, a sewage pipe 7 is installed at the bottom of the filter cartridge 4, and an electric control valve is installed in the sewage pipe 7. When purifying water, the three-way valve 21 of the water inlet pipe 2 is opened to guide tap water into between the filter cartridge 4 and the filter element 5, and impurities in the tap water are blocked outside the filter element 5. The filtered water flows into the water pipe 51 and is discharged from the water outlet pipe 3 on the right side of the water flow area after aggregation.

[0023] Preferably, in one embodiment, Figure 1-Figure 3 As shown, the cleaning mechanism 6 is composed of a cleaning ring 61, a pulling rope 62, a scraper 63, and an extrusion block 64. The diameter of the cleaning ring 61 is consistent with the spacing diameter between the filter cartridge 4 and the filter element 5. The cleaning ring 61 is filled with gas and has partial buoyancy. The top surfaces of the cleaning ring 61 are connected to the top of the filter cartridge 4 on both sides through the pulling rope 62. The pulling rope 62 is an elastic rope structure as a whole. The inner circumference of the cleaning ring 61 is arranged with scrapers 63 in a circular array. The scrapers 63 are inclined, and the bottom and top of adjacent scrapers 63 are aligned. They are on the same vertical line. When filtering tap water, when water enters the filter cartridge 4, it impacts and squeezes the cleaning circle 61 downward, so that the scraper 63 of the cleaning circle 61 scrapes and cleans the surface of the filter element 5. After the water passes through the filter element 5 and enters the water pipe 51, the cleaning circle 61 is driven to reset by the pulling rope 62. The surface of the filter element 5 can be scraped every time the water is filtered to prevent excessive impurities from entering the filter element 5 and increasing the difficulty of cleaning. After the water has entered the filter cartridge 4 ten times, the electric control valve in the sewage pipe 7 is automatically opened to discharge the impurities at the bottom of the filter cartridge 4.

[0024] Preferably, in one embodiment, Figure 3As shown, an extrusion block 64 is installed on the wall of the scraper 63 facing the filter element 5. The extended end face of the extrusion block 64 is an arc-shaped structure. The extrusion block 64 is located at the interval of the micropores of the filter element 5. The setting of the extrusion block 64 facilitates the extrusion of impurities that have entered the micropores of the filter element 5.

[0025] Preferably, in one embodiment, a backflush valve 52 is installed at the bottom of the water pipe 51, and the backflush valve 52 is in a closed state during water filtering operation. When cleaning the filter element 5, tap water is introduced into the water flow area through the three-way valve 21 to allow water to enter the water pipe 51. At the same time, the backflush valve 52 is opened to allow water to continuously clean the inside of the water pipe 51, and the cleaned water is directly discharged into the sewage pipe 7.

[0026] Preferably, in one embodiment, support rods 41 are installed on the inner bottom surface of the filter cartridge 4, and the support rods 41 are arranged in a circular array. Through the setting of the support rods 41, the bottom of the cleaning circle 61 is limited to prevent excessive impact from causing the pulling rope 62 to break.

[0027] Working principle of this utility model:

[0028] During operation, when filtering tap water, when water enters the filter cartridge 4, it impacts and squeezes the cleaning circle 61 downward, so that the scraper 63 of the cleaning circle 61 scrapes and cleans the surface of the filter element 5. After the water passes through the filter element 5 and enters the water pipe 51, the cleaning circle 61 is driven to reset by the pulling rope 62. The surface of the filter element 5 can be scraped every time the water is filtered to prevent excessive impurities from entering the filter element 5 and increasing the difficulty of cleaning. For example, after the water is fed in ten times, the electric control valve in the sewage pipe 7 is automatically opened to discharge the impurities at the bottom of the filter cartridge 4, and the tap water is introduced into the water flow area through the three-way valve 21 to allow the water to enter the water pipe 51. At the same time, the backflush valve 52 is opened to allow the water to continuously clean the inside of the water pipe 51, and the cleaned water is directly discharged into the sewage pipe 7.

[0029] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
