[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The utility model provides a technical solution: a drinking water filter that is easy to replace the filter screen, including: an installation box 1, a support frame 2, a motor 3, a filter screen 4, a water inlet 5, a water outlet 6, a sewage outlet 7, a cover plate 8, a first clamping block 9, a mounting block 10, a second clamping block 11, a spring 12, a connecting shaft 13, a roller 14, a mounting plate 15, a connecting rod 16, a brush plate 17, a fixing block 18, a connecting plate 19 and a pressure difference control plate 20.

[0030] When using this drinking water filter that is easy to replace the filter, first Figure 1 and Figure 2 As shown, the support frame 2 is fixedly mounted on the lower end of the mounting box 1, and the motor 3 is fixedly mounted on the middle part of the upper end of the cover plate 8, the filter screen 4 is mounted in the middle part of the mounting box 1, and the lower end of the mounting box 1 is arranged in an arc-shaped structure, the lower end of the mounting box 1 is fixedly mounted with a sewage outlet 7, and the upper end of the sewage outlet 7 passes through the lower end of the filter screen 4, the upper and lower ends of the mounting box 1 are respectively fixedly mounted with a water inlet 5 and a water outlet 6, the upper end of the mounting block 10 is fixedly connected to the output end of the motor 3, and the connecting shaft 13 is rotatably connected to the inside of the mounting box 1 through the mounting block 10, a brush plate 17 is fixedly mounted on the outside of the connecting shaft 13, and the brush plate 17 is slidably connected to the inner side of the filter screen 4, the upper end of the filter screen 4 is mounted with a connecting plate 19, and the upper end of the connecting plate 19 is inwardly inclined.

[0031] The drinking water to be filtered is injected into the interior of the installation box 1 from the water inlet 5. At this time, the water flows to the inside of the filter 4 through the connecting plate 19. The motor 3 starts to control the installation block 10 to drive the connecting shaft 13 to rotate. The connecting shaft 13 drives the brush plate 17 to slide at a uniform speed on the inside of the filter 4, and the impurities attached to the inside of the filter 4 are brushed off to the bottom of the filter 4 to prevent the filter 4 from being blocked and reducing the filtering effect, and prolonging the time that the filter 4 is used inside the filter. The pressure difference control board 20 fixed at the front end of the installation box 1 controls the pressure inside the installation box 1, so that the clean drinking water passing through the filter 4 is discharged from the filter from the water outlet 6, and the impurities gathered at the lower end of the filter 4 can be discharged from the inside of the sewage outlet 7. Open the valve of the sewage outlet 7 and combine it with the impact of the water flow to quickly discharge the impurities.

[0032] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the cover plate 8 is slidably connected to the upper end of the installation box 1, and the first clamping block 9 is engaged with the groove provided on the outer ring of the cover plate 8, and the first clamping block 9 is arranged in an annular shape at equal angles along the center point of the cover plate 8. The first clamping block 9 is arranged in an "L" shape, and the lower end of the first clamping block 9 is rotatably connected to the upper end of the installation box 1 through a torsion spring;

[0033] When it is necessary to open the cover 8, the first clamping block 9 is pulled outward so that the first clamping block 9 leaves the groove of the cover 8, and the handle of the cover 8 is pulled upward to remove the cover 8 and the motor 3. The first clamping block 9 applies pressure to the first clamping block 9 through the elastic action of the torsion spring, so that the first clamping block 9 can be stably engaged with the inner side of the cover 8, which facilitates the quick disassembly and assembly of the cover 8 and the installation box 1, saving working time;

[0034] The second clamping block 11 is slidably connected to the inside of the mounting block 10, and a spring 12 is sleeved on the outer side of the middle part of the second clamping block 11, and the two ends of the spring 12 are fixedly connected to the mounting block 10 and the second clamping block 11 respectively, the inner end of the second clamping block 11 is engaged with the groove opened on the inner side of the upper end of the connecting shaft 13, and the lower side of the outer end of the second clamping block 11 is arranged in an inclined structure, the second clamping block 11 is slidably connected to the roller 14 and the mounting plate 15, the roller 14 is rotatably connected to the inner side of the mounting plate 15 through the second clamping block 11, and the roller 14 is arranged in an annular shape at equal angles along the center point of the mounting plate 15, and the mounting plate 15 is a circular ring structure, and a connecting rod 16 is fixedly installed on the outer end of the mounting plate 15, and the outer end of the connecting rod 16 is slidably connected to the inner side of the upper end of the mounting box 1;

[0035] When the cover plate 8 is lifted up, the motor 3 drives the mounting block 10 to move up. At this time, the second clamping block 11 drives the connecting shaft 13 to move upward. When the horizontal position of the second clamping block 11 is higher than the mounting plate 15, the spring 12 restores its elastic deformation and pushes the second clamping block 11 to move outward. The inner end of the second clamping block 11 stops being engaged with the connecting shaft 13, and the connecting shaft 13 is separated from the mounting block 10. Then, the connecting rod 16 is held and removed from the mounting box 1, which is convenient for the subsequent removal of the filter screen 4. This operation method is simple and fast, and the automatic disassembly and assembly of the mounting block 10 and the connecting shaft 13 are completed according to the opening and installation of the cover plate 8, which saves working time and is convenient for the subsequent quick removal of the filter screen 4.

[0036] The fixing block 18 is fixedly mounted on the upper end of the filter screen 4 and is arranged in an "L"-shaped structure. The fixing block 18 is slidably connected to a groove provided inside the connecting plate 19. The connecting plate 19 is slidably connected to the upper end of the filter screen 4.

[0037] Hold the handle on the upper end of the connecting plate 19 and rotate it. The connecting plate 19 rotates so that the fixing block 18 slides with it. When the vertical groove of the connecting plate 19 corresponds to the fixing block 18, pull the connecting plate 19 upward so that the connecting plate 19 leaves the outside of the fixing block 18, completing the quick removal of the connecting plate 19. Then, take out the filter 4 from the inside of the installation box 1 for cleaning and replacement, saving the time and energy required for removing the filter 4 and facilitating operation and learning.
