[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sterile pre-wetting hydrophobic polytetrafluoroethylene capsule filter element, including a filter element shell, an easy-to-disassemble mechanism provided on the inner wall of the filter element shell, a cleaning mechanism provided on the outer wall of the easy-to-disassemble mechanism, and the easy-to-disassemble mechanism includes a common filter layer.

[0007] A filter media layer is fixedly connected to the top of the ordinary filter layer, and a support layer is fixedly connected to the top of the filter media layer. A filter element fixing block is fixedly connected to the inner wall of the filter element shell. Several filter element fixing blocks are present. A sliding groove is formed on the inner wall of the filter element shell, and a fixed slider is slidably connected to the inner wall of the groove. The outer wall of the fixed slider is fixedly connected to the outer surface of the support layer, the outer wall of the fixed slider is fixedly connected to the outer surface of the filter media layer, and the outer surface of the ordinary filter layer. A slider fixing block is fixedly connected to the outer surface of the filter element shell. The quantity is several. A trapezoidal slider is fixedly connected to the top of the slider fixing block. A locking block is slidably connected to the outer surface of the trapezoidal slider. A cover plate is fixedly connected to the side of the locking blocks that are close to each other. A handle is fixedly connected to the top of the cover plate. A rotating shaft is fixedly connected to the bottom of the cover plate. A spring top block is fixedly connected to the bottom of the rotating shaft. A spring is fixedly connected to the bottom of the spring top block. A spring bottom block is fixedly connected to the bottom of the spring. A limiting plate is fixedly connected to the outer wall of the spring bottom block. A telescopic rod is fixedly connected to the top of the spring bottom block. The top of the telescopic rod is fixedly connected to the bottom of the spring top block.

[0008] Furthermore, the cleaning mechanism includes a water tank, the outer wall of which is fixedly connected to the outer surface of the filter element housing.

[0009] Furthermore, a water tank fixing block is fixedly connected to the bottom of the water tank, and the outer wall of the water tank fixing block is fixedly connected to the outer surface of the filter element shell.

[0010] Furthermore, a water pipe is fixedly connected to the inner wall of the water tank, and the top of the water pipe penetrates the inner wall of the water tank and extends to the outside.

[0011] By placing the cover plate on the filter cartridge housing, the spring and telescopic rod will compress when the cover plate and the filter cartridge housing overlap, thus preventing the limiting plate from damaging the filter cartridge. By rotating the cover plate, the trapezoidal slider is pushed into the locking block for fixation, thereby securing the cover plate.

[0012] Furthermore, a water pump is fixedly connected to the bottom of the water pipe, and a pumping pipe is fixedly connected to the bottom of the water pump.

[0013] Furthermore, a filter screen fixing plate is slidably connected to the inner wall of the water tank, and a filter screen is fixedly connected to the inner wall of the filter screen fixing plate.

[0014] Furthermore, a filter handle is fixedly connected to the outer wall of the filter screen fixing plate, and a water injection pipe is fixedly connected to the top of the water tank. The bottom of the water injection pipe passes through the top of the water tank and extends into the interior.

[0015] Furthermore, a water pipe fixing bracket is fixedly connected to the outer wall of the filter element housing. There are two water pipe fixing brackets. The top of the water pipe passes through the inner wall of the water pipe fixing bracket and extends to the outside. A rotating shaft is fixedly connected to the top of the water pipe. A water spray head is rotatably connected to the top of the rotating shaft.

[0016] By injecting water into the water inlet pipe, the water flows through the filter screen and filters out some impurities in the water. Pulling the filter handle allows the filter screen to be pulled out for cleaning. By starting the water pump, the water in the water tank is drawn out through the water inlet pipe. The water flows through the water pipe to the spray head. By rotating the spray head, the rotating shaft two will drive the spray head to rotate. When the water reaches the spray head, it will be sprayed onto the filter element.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model features a convenient disassembly mechanism. The ordinary filter layer is inserted into the filter cartridge housing by a sliding block within a groove. When the filter cartridge reaches its lowest point, a fixing block secures it. At this point, a cover plate is placed on the filter cartridge housing. When the cover plate and housing overlap, the spring and telescopic rod compress, preventing the limiting plate from damaging the filter cartridge. Rotating the cover plate then pushes the trapezoidal slider into the locking block for fixation, thus securing the cover plate. The advantages of this design include securing the filter cartridge, facilitating easy disassembly and replacement when the filter cartridge reaches the end of its service life, and making installation convenient.

[0019] 2. This utility model incorporates a cleaning mechanism. Water is injected into the water inlet pipe, and the water flows through the filter screen to remove some impurities. Pulling the filter handle allows the filter screen to be pulled out for cleaning. When the water tank is full, the water pump is activated to draw water from the tank through the suction pipe. The water then flows through the water pipe to the spray head. Rotating the spray head causes the rotating shaft to rotate, and the water is sprayed onto the filter element when it reaches the spray head. This effectively cleans the used filter element, preventing residual substances from further corroding it and affecting its lifespan.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A filter screen 207 is connected to filter the water entering the water tank 201. A filter handle 208 is fixedly connected to the outer wall of the filter screen fixing plate 206. A water inlet pipe 209 is fixedly connected to the top of the water tank 201, through which water is added to the water tank 201. The bottom of the water inlet pipe 209 passes through the top of the water tank 201 and extends into the interior. Two water pipe fixing brackets 210 are fixedly connected to the outer wall of the filter element housing 101. The top of the water pipe 205 passes through the inner wall of the water pipe fixing bracket 210 and extends to the outside. A rotating shaft 211 is fixedly connected to the top of the water pipe 205. A water spray head 212 is rotatably connected to the top of the rotating shaft 211, through which water is sprayed out to clean the filter element.

[0035] Water is drawn from water tank 201 by water pump 204 and sucked into water pump 204 through water pipe 203. The filter screen fixing plate 206 and filter screen 207 are pulled out through filter handle 208 for easy cleaning. Water is sprayed out through water spray head 212 by rotating shaft 211.

[0036] A specific application of this embodiment is as follows: The operator first inserts the ordinary filter layer 102 into the filter cartridge housing 101, sliding the fixed slider 111 within the groove 110. When it reaches the bottom, the filter cartridge fixing block 117 will lock the filter cartridge in place. At this point, the cover plate 105 is placed on the filter cartridge housing 101. When the cover plate 105 and the filter cartridge housing 101 overlap, the spring 113 and the telescopic rod 114 will compress, thus preventing the limiting plate 107 from damaging the filter cartridge. Then, the cover plate 105 is rotated, pushing the trapezoidal slider 108 into the locking block 109 for fixation, thereby securing the cover plate 105. The advantage of this is that it secures the filter cartridge and facilitates disassembly and replacement when the filter cartridge reaches the end of its service life. It is easy to install. When the filter element needs to be cleaned, water is added to the water inlet pipe 209. At this time, the water flows through the filter screen 207 and filters some impurities in the water. Pulling the filter handle 208 can pull out the filter screen 207 for cleaning. When the water tank is full, the water pump 204 is started to draw the water in the water tank 201 out through the water suction pipe 203. At this time, the water flows through the water pipe 205 to the spray head 212. At this time, the spray head 212 is rotated, and the rotating shaft 211 will drive the spray head 212 to rotate. When the water reaches the spray head 212, it will spray onto the filter element. The benefit is to clean the filter element after use and prevent the residual substances on the filter element from further corroding the filter element, thereby affecting its service life.
