Filtration is the process of liquid in a suspension passing through a medium under the action of a driving force or other external force, and solid particles and other substances are retained by the filter medium. At present, the mainstream process for preparing direct drinking water on the market is a membrane treatment process with reverse osmosis as the core, that is, through filtration, softening, membrane separation (RO reverse osmosis), sterilization and other methods, harmful heavy metals, organic matter, bacteria, viruses and other impurities in the water are removed to make it high-quality drinking water (pure water).

[0003] According to Chinese patent announcement number: CN116332256A, a direct drinking water filter device that is easy to clean includes a filter body, a ceramic filter element is arranged on the filter body, a mounting plate is arranged on the side of the filter body, a cleaning part is arranged on the mounting plate, and the cleaning part includes a valve assembly and a rotating assembly; the valve assembly includes a mounting seat, a groove is arranged on the top of the mounting seat, a through groove and a liquid discharge flow channel are arranged in the groove, a valve body is arranged in the through groove, a liquid inlet flow channel is arranged inside the valve body, a first elastic member and a sealing ball are arranged inside the liquid inlet flow channel, a second elastic member is arranged in the groove, a ring member is arranged at the telescopic end of the second elastic member, a connecting rod is arranged on the inner side of the ring member, and a push rod is arranged at the bottom of the connecting rod; the rotating assembly includes a supporting shaft, a driving wheel is arranged on the supporting shaft, a spline shaft is arranged on the driving wheel, a floating block is arranged on the spline shaft, a protrusion is arranged on the outer periphery of the floating block, a spline groove is arranged through the floating block, and the spline shaft passes through the spline groove. By setting up a valve assembly and a rotating assembly, when cleaning the ceramic filter element, the water flow is controlled by opening and closing the valve assembly. After the valve assembly is opened, the water flow pressure can drive the rotating assembly to rotate. Since the rotating assembly is provided with a driving wheel and a floating block, as the water flows, the water flows through the guide groove on the driving wheel, causing the driving wheel to rotate, and further drives the floating block to rotate under the cooperation of the spline shaft and the spline groove, so that the protrusions on the outer periphery of the floating block rub against the inner wall of the ceramic filter element, so that the attached dirt is removed by scraping by the protrusions. However, when using the above device, the floating block moves in the same direction on the spline shaft. When the water flows, the floating block moves with the increase of water volume. When cleaning is required, the water flow rate needs to be controlled, which makes the cleaning operation cumbersome and affects the cleaning efficiency.

By setting up a valve assembly and a rotating assembly, when cleaning the ceramic filter element, the water flow is controlled by opening and closing the valve assembly. After the valve assembly is opened, the water flow pressure can drive the rotating assembly to rotate. Since the rotating assembly is provided with a driving wheel and a floating block, as the water flows, the water flows through the guide groove on the driving wheel, causing the driving wheel to rotate, and further drives the floating block to rotate under the cooperation of the spline shaft and the spline groove, so that the protrusions on the outer periphery of the floating block rub against the inner wall of the ceramic filter element, so that the attached dirt is removed by scraping by the protrusions. However, when using the above device, the floating block moves in the same direction on the spline shaft. When the water flows, the floating block moves with the increase of water volume. When cleaning is required, the water flow rate needs to be controlled, which makes the cleaning operation cumbersome and affects the cleaning efficiency.

[0036] Therefore, when using the above device, the operation is cumbersome and affects the cleaning efficiency.

[0037] In response to the above technical problems, the present application has made the following designs and ideas: In order to solve the problems existing in the prior art, it is envisaged that a certain reciprocating mechanism can achieve a better effect of removing impurities than the floating blocks in the prior art that move with the increase of water volume, thereby achieving the purpose of quickly removing impurities and improving the removal efficiency.

[0038] The following is combined with Figures 1 to 4 The utility model is further introduced in detail.

[0041] The adjusting component 4 is arranged at the bottom of the installation tube 1 . The adjusting component 4 is used to collect sediment in the water, and the adjusting component 4 is used to adjust the linkage relationship of the cleaning component 3 inside the installation tube 1 .

[0042] Through the cooperation between the cleaning component 3 and the adjusting component 4, when the impurities of the mounting cylinder 1 and the filter cylinder 2 are cleaned after long-term use, the cleaning component 3 makes an up and down reciprocating motion inside the mounting cylinder 1, and the cleaning component 3 cleans the impurities on the outer wall of the filter cylinder 2. At the same time, the adjusting component 4 and the bottom wall of the mounting cylinder 1 produce an opening, and the impurities on the bottom of the mounting cylinder 1 and the outer wall of the filter cylinder 2 are discharged from the opening at the same time, so that the impurities of the mounting cylinder 1 and the filter cylinder 2 are cleaned conveniently and quickly, thereby improving the cleaning efficiency.

[0043] Specifically, Figure 2 and Figure 3 As shown, the removal component 3 includes:

[0044] The rotating rod 31 is rotatably mounted on the inner wall of the mounting tube 1 . Specifically, the top of the rotating rod 31 is rotatably mounted on the inner top end of the mounting tube 1 .

[0045] The movable shaft 32 is movably connected to the rotating rod 31 . Further, when the rotating rod 31 rotates, the movable shaft 32 can move back and forth up and down on the rotating rod 31 .

[0046] The cleaning block 33 is fixedly connected to the movable shaft 32 at its edge, and the middle of the cleaning block 33 is attached to the outer side of the filter cartridge 2. Furthermore, a plurality of openings are evenly arranged at the edge of the cleaning block 33 for water to flow from top to bottom.

[0047] The connecting gear 34 is fixedly connected to the bottom end of the rotating rod 31 .

[0048] Furthermore, when the water flows rapidly from top to bottom, the rotating rod 31 rotates, and then the movable shaft 32 drives the cleaning block 33 to move back and forth up and down on the outside of the filter cartridge 2. The cleaning block 33 cleans the outside of the filter cartridge 2, thereby removing impurities on the outside of the filter cartridge 2 and improving the filtering effect of the filter cartridge 2.

[0049] Specifically, Figure 2 and Figure 3 As shown, the rotating rod 31 is provided with a slide groove which is adapted to and connected to the movable track of the movable shaft 32 and has a size corresponding to that of the movable shaft 32 .

[0050] Furthermore, when the rotating rod 31 rotates, the movable shaft 32 drives the cleaning block 33 to move back and forth up and down on the outside of the filter cartridge 2, and the cleaning block 33 cleans the outside of the filter cartridge 2, thereby removing impurities on the outside of the filter cartridge 2, thereby improving the cleaning effect of the cleaning block 33 on the filter cartridge 2.

[0051] Specifically, Figure 2 and Figure 3 As shown, the adjustment component 4 includes:

[0052] There are two fixing rods 41 , which are symmetrically fixed to the bottom of the installation tube 1 .

[0055] The connecting structure 43 is fixedly connected to the bottom plate 44 , and the connecting structure 43 extends to a position close to the cleaning component 3 .

[0056] Furthermore, when discharging impurities, the bottom plate 44 is pulled down, and the bottom plate 44 drives the sealing block 46 to separate from the bottom of the mounting tube 1, thereby forming an opening between the bottom plate 44 and the bottom of the mounting tube 1, and the impurities at the bottom of the mounting tube 1 and cleaned from the outside of the filter tube 2 are discharged. When the impurities in the water are removed normally, the bottom plate 44 is loosened, and under the reaction force of the spring 45, the bottom plate 44 drives the sealing block 46 to be clamped on the bottom of the mounting tube 1, so that the bottom plate 44 and the bottom of the mounting tube 1 fit together.

[0057] Specifically, through holes corresponding to the positions and sizes of the blocking blocks 46 are evenly arranged at the bottom of the installation tube 1, and the blocking blocks 46 are arranged in the through holes.

[0058] Furthermore, when the spring 45 contracts, the bottom plate 44 drives the sealing block 46 to be set in the through hole, and the bottom plate 44 fits with the bottom of the mounting tube 1, and the water flow inside the mounting tube 1 will not flow out from the through hole. When the bottom plate 44 is pulled and the spring 45 is extended, the bottom plate 44 drives the sealing block 46 to separate from the through hole, and the impurities at the bottom of the mounting tube 1 and the impurities cleaned from the outside of the filter tube 2 are discharged from the through hole.

[0059] Specifically, Figure 3 and Figure 4 As shown, the connection structure 43 includes:

[0060] The connecting rod 431 is fixedly connected to one side of the connecting block 42. Specifically, the connecting rod 431 is L-shaped.

[0061] The mounting block 432 is fixedly connected to the top of the end of the connecting rod 431 away from the connecting block 42 . Specifically, the mounting block 432 is hollow, and the rotating rod 31 passes through the middle of the mounting block 432 and extends to the bottom of the mounting block 432 .

[0062] The transmission gear 434 is fixedly connected to the rotating rod 433 , and the rotating rod 433 is rotatably mounted on the mounting block 432 . Specifically, the mounting angle of the rotating rod 433 is parallel to the mounting angle of the mounting block 432 .

[0063] The toggle wheel 435 is fixedly connected to one end of the rotating rod 433 away from the connecting rod 431 .

[0064] Furthermore, when the bottom plate 44 is pulled, the bottom plate 44 drives the connecting rod 431 to move downward, and the connecting rod 431 moves downward through the mounting block 432, so that the transmission gear 434 is connected to the connecting gear 34. At this time, an opening is generated at the bottom plate 44 and the bottom of the mounting cylinder 1, and water flows out from the opening, thereby improving the flow effect of the water flow, and then the water drives the rotating rod 433 to rotate through the toggle wheel 435, and the rotating rod 433 drives the connecting gear 34 to rotate through the transmission gear 434, and then the connecting gear 34 drives the rotating rod 31 to rotate, so as to remove impurities on the outside of the filter cylinder 2.

[0065] More preferably, the connecting gear 34 and the transmission gear 434 are both bevel gears, and the transmission gear 434 is transmission-connected to the connecting gear 34 .

[0066] Furthermore, when the connecting gear 34 is meshed with the transmission gear 434 , the transmission stability between the connecting gear 34 and the transmission gear 434 is improved.

A drainage pipe 6 is installed at the middle position of the upper part of the installation cylinder 1, and the input end of the drainage pipe 6 is arranged on the upper part of the filter cylinder 2.

[0068] Furthermore, water flows from the water inlet pipe 5 into the inner edge of the installation cylinder 1, and then flows through the outer wall of the filter cylinder 2 into the inner wall. The filter cylinder 2 filters impurities in the water, and the impurities adhere to the outer wall of the filter cylinder 2. The filtered water flows out through the upper drain pipe 6 of the filter cylinder 2.

[0069] How it works

[0070] Water flows from the water inlet pipe 5 to the inner edge of the installation cylinder 1, and then flows through the outer wall of the filter cylinder 2 into the inner wall. The filter cylinder 2 filters impurities in the water, and the impurities adhere to the outer wall of the filter cylinder 2. The filtered water flows out through the drainage pipe 6 on the upper part of the filter cylinder 2. When the impurities inside the installation cylinder 1 and the outer wall of the filter cylinder 2 are removed, the bottom plate 44 is pulled down, and the bottom plate 44 drives the blocking block 46 to separate from the bottom of the installation cylinder 1, and then an opening appears between the bottom plate 44 and the bottom of the installation cylinder 1, and the bottom plate 44 drives the connecting rod 431 to move downward, and the connecting rod 431 passes through the installation cylinder 1. Block 432 moves downward, so that the transmission gear 434 is connected to the connecting gear 34. At this time, an opening is generated at the bottom plate 44 and the bottom of the installation cylinder 1, and water flows out from the opening, thereby improving the flow effect of the water flow. Then the water drives the rotating rod 433 to rotate through the toggle wheel 435, and the rotating rod 433 drives the connecting gear 34 to rotate through the transmission gear 434, and then the connecting gear 34 drives the rotating rod 31 to rotate, so that the impurities on the outside of the filter cylinder 2 are removed, and then the impurities inside the installation cylinder 1 and the impurities on the filter cylinder 2 are discharged through the opening.

[0071] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
