In addition, when the cover body and the filter plate are combined and outside the filter shell, the rectangular plate can be manually pressed to allow multiple through-columns to pass through the through holes and the filter holes at the same time to push down the impurities attached to the filter hole walls, thereby making it easier for the staff to clean the filter plate and reducing the difficulty of cleaning the filter plate.

[0018] 2. The water purifier pump head described in the present invention can seal the connection between the external water supply pipe and the threaded pipe by using a sealing ring, thereby avoiding water leakage during the water pumping process.

[0019] 3.

[0025] In this embodiment, Figure 1-Figure 7 , Fig. 9 , Fig.10 As shown, a threaded rod 9 is threadedly connected to the lower end of the rear side of the mounting plate 10, and the right end of the threaded rod 9 is rotatably arranged on the filter housing 3; The upper end surface of the mounting plate 10 is fixedly connected to a slide rail 3 26, and the slide rail 3 26 is plugged and slidably connected to the cover body 11; A spring 2 16 is fixedly connected to the front side of the upper end of the cover body 11, and the rear end of the spring 2 16 is fixedly connected to the mounting plate 10; A plug post 14 is fixedly connected to the middle of the front side of the right end face of the cover body 11, and a plug hole 23 is provided in the middle of the front side of the left end face of the filter plate 21, and the plug post 14 can be plugged into the plug hole 23; The mounting plate 10 is penetrated and slidably connected with a plurality of through-columns 12, the left end of which is fixedly connected with a rectangular plate 13, and the cover body 11 is provided with a plurality of through-holes 29, through which the through-columns 12 can pass through the through-holes 29 and the filter holes 22; A connecting block 30 is fixedly connected to the middle of the lower end surface of the rectangular plate 13, a spring 20 is fixedly connected to the right end surface of the connecting block 30, and the right end of the spring 20 is fixedly connected to the mounting plate 10; Specifically, a water purifier, also known as a water purifier or a water purifier, is a water treatment device specially used for deep filtering and purifying water. The water purifier pump head, as a key component in the water purifier, mainly refers to a combination including an impeller, a bearing, an oil ring and a sealing rotating component. These components work together to achieve the water delivery and pressurization functions. When the existing water purifier pump head is in use, a filter screen is set at the water inlet pipe 4 to filter impurities in the water to ensure the water quality. When the filter screen needs to be cleaned, the filter screen can be taken out from the water inlet pipe 4 for cleaning. However, when the filter screen is taken out, it is taken out from the end of the water inlet pipe 4, which means that the water inlet pipe 4 needs to be separated from the external water supply pipeline. Therefore, it is necessary to first separate the water inlet pipe 4 from the external water supply pipeline, and then take out the filter screen. After the cleaning is completed, the water inlet pipe 4 is connected to the external water supply pipeline. The whole process is relatively troublesome, which delays the normal operation of the water purifier pump head. Therefore, in order to solve the above problems, when using the present embodiment, the external water supply pipe is plugged into the inner cavity of the threaded pipe 5, and the external water supply pipe and the threaded pipe 5 are threadedly connected by connecting the thread 17, and then the water purifier pump head body 1 is used to pump water into the threaded pipe 5, and then the water is discharged from the water outlet pipe 2 after passing through the filter shell 3 and the water inlet pipe 4, and the filter plate 21 can be used to intercept impurities in the water to prevent impurities from entering the water purifier pump head body 1, thereby ensuring the water quality; When more impurities accumulate on the surface of the filter plate 21, the water purifier pump head body 1 stops working, and water no longer enters the filter housing 3. Then, the threaded rod 9 is manually rotated to drive the mounting plate 10 to slide from right to left, so that the access port 8 is no longer covered by the sealing cover plate 15. At this time, the filter plate 21 can be removed from the slide rail 24 by sliding, and then the filter plate 21 can be cleaned. The whole process does not require the external water supply pipe to be removed from the threaded pipe 5, which is more convenient. In addition, it is also convenient to install the cleaned filter plate 21 back into the filter housing 3 again, so that the water purifier pump head body 1 can quickly resume working state. Due to the different installation angles of the water purifier pump head body 1, when the filter plate 21 is in a flat state, impurities will fall on the surface of the filter plate 21 under the action of gravity, and the filter plate 21 will receive the impurities. When the filter plate 21 is taken out, the impurities are also taken out together. When the filter plate 21 is in a vertical state, some impurities may not be attached to the surface of the filter plate 21, but to the inner wall of the filter shell 3 on one side of the filter plate 21. These impurities do not contact the surface of the filter plate 21. Therefore, when only the filter plate 21 is taken out, the impurities will still remain on the inner cavity wall of the filter shell 3. After accumulation, they will still block the filter holes 22 of the filter plate 21, affecting the normal operation of the filter plate 21. Therefore, after the access port 8 is opened, the cover body 11 is pushed to slide on the slide rail 3 26 to allow the cover body 11 to enter the pass In the filter housing 3, the second spring 16 is compressed, and the edge of the cover body 11 fits against the inner wall of the filter housing 3, the plug post 14 is aligned with the insertion hole 23, and then the threaded rod 9 is rotated again to make the cover body 11 close to the filter plate 21. When the cover body 11 is close to the filter plate 21, the impurities on the inner wall of the filter housing 3 can be scraped. When the plug post 14 is fully inserted into the insertion hole 23, the impurities are collected in the cavity of the cover body 11. At this time, the cover body 11 is released, and the second spring 16 is restored, so that the cover body 11 and the filter plate 21 can be moved out of the filter housing 3 together, and then the impurities inside the cover body 11 can be removed, thereby realizing the removal of impurities attached to the inner wall of the filter housing 3, avoiding the situation that the filter holes of the filter plate 21 are blocked due to the accumulation of impurities on the inner wall of the filter housing 3, thereby affecting the water flow efficiency. Furthermore, when the cover body 11 and the filter plate 21 are combined and outside the filter housing 3, the spring 20 can be compressed by manually pressing the rectangular plate 13, and the plurality of through-columns 12 simultaneously pass through the through hole 29 and the filter hole 22 to push down the impurities attached to the hole wall of the filter hole 22, and then the rectangular plate 13 is released, and the spring 20 is restored, so that it is easier for the staff to clean the filter plate 21, and the difficulty of cleaning the filter plate 21 is reduced; The filter plate 21 is then removed from the filter housing 3 and the filter housing 3 is then removed from the filter housing 3. The filter housing 3 is then removed from the filter housing 3 and the filter housing 3 is then removed from the filter housing 3. The filter housing 11 is then opened and the filter plate 21 is moved out of the filter housing 3. The filter housing 11 is then opened and the filter plate 21 is moved out of the filter housing 3. The filter plate 21 is then opened and the filter plate 21 is moved out of the filter housing 3. The filter plate 21 is then opened and the filter plate 21 is moved out of the filter housing 3.

[0026] In this embodiment, Figure 1 As shown, a sealing ring 6 is sleeved on the left side of the threaded tube 5; Specifically, the sealing ring 6 can seal the connection between the external water supply pipe and the threaded pipe 5, thereby preventing water from leaking out during the water pumping process.

[0027] In this embodiment, Figure 1 and Figure 8 As shown, a fixing plate 27 is sleeved and fixedly connected to the upper side of the water purifier pump head body 1, and a plurality of connecting holes 7 are provided on the fixing plate 27; A connecting rod 28 is fixedly connected to the middle of the rear side of the water purifier pump head body 1, and a connecting plate 18 is fixedly connected to the rear end of the connecting rod 28. A plurality of connecting holes 19 are provided on the connecting plate 18; Specifically, by using the multiple connection holes 1 7 on the fixing plate 27 and the multiple connection holes 2 19 on the connecting plate 18 , the water purifier pump head body 1 can be installed in a suitable position, which is relatively convenient.

[0028] Working principle: The water purifier pump head body 1 can be installed in a suitable position by using the multiple connection holes 17 on the fixing plate 27 and the multiple connection holes 2 19 on the connecting plate 18, which is relatively convenient.

In addition, the filter plate 21 can be used to intercept impurities in the water to prevent impurities from entering the water purifier pump head body 1, thereby ensuring Water quality; when more impurities accumulate on the surface of the filter plate 21, the water purifier pump head body 1 stops working, and water no longer enters the filter shell 3. Then the threaded rod 9 is manually rotated to drive the mounting plate 10 to slide from right to left, so that the access port 8 is no longer covered by the sealing cover plate 15. At this time, the filter plate 21 can be removed from the slide rail 24 by sliding, and then the filter plate 21 can be cleaned.

When the filter plate 21 is taken out, the impurities are also taken out together. When the filter plate 21 is in a vertical state, some impurities may not be attached to the surface of the filter plate 21, but attached to the inner wall of the filter shell 3 on one side of the filter plate 21. These impurities do not contact the surface of the filter plate 21. Therefore, when only the filter plate 21 is taken out, the impurities will still remain on the inner cavity wall of the filter shell 3. After accumulation, they will still block the filter holes 22 of the filter plate 21, affecting the normal operation of the filter plate 21.

When the cover body 11 is close to the filter plate 21, the impurities on the inner wall of the filter shell 3 can be scraped. When the plug post 14 is fully inserted into the insertion hole 23, the impurities are collected in the cavity of the cover body 11. At this time, the cover body 11 is loosened, and the spring 16 is restored, so that the cover body 11 and the filter plate 21 can be moved out of the filter shell 3 together, and then the impurities inside the cover body 11 can be cleared, thereby realizing the removal of impurities attached to the inner wall of the filter shell 3, avoiding the situation that the filter holes of the filter plate 21 are blocked due to the accumulation of impurities on the inner wall of the filter shell 3, thereby affecting the water flow efficiency;Furthermore, when the cover body 11 is combined with the filter plate 21 and is outside the filter shell 3, the spring 20 can be compressed by manually pressing the rectangular plate 13, and the plurality of through-columns 12 simultaneously pass through the through hole 29 and the filter hole 22 to push down the impurities attached to the hole wall of the filter hole 22, and then the rectangular plate 13 is released, and the spring 20 is restored, so that it is easier for the staff to clean the filter plate 21, and the difficulty of cleaning the filter plate 21 is reduced; thus, the impurities in the water can be intercepted by the filter plate 21 by using the pull-out filtering mechanism to prevent the impurities from entering the water purifier. The inside of the pump head body 1 ensures the water quality, and when more impurities accumulate on the surface of the filter plate 21, the threaded rod 9 is manually rotated to drive the mounting plate 10 to slide from right to left, so that the access port 8 is no longer covered by the sealing cover plate 15, and the filter plate 21 can be removed from the slide rail 24 by sliding, and then the filter plate 21 can be cleaned.
