A sealing ring 9 is fixedly embedded in the connecting sleeve 5, and the sealing ring 9 is sealed and slidably connected to the water inlet pipe 2. The diameters of the cylinder frame 4, the connecting sleeve 5 and the connecting cover 6 are the same.

[0025] Specifically, by setting the sealing sleeve 7 and the sealing ring 9, the sealing performance of the metal sintered felt filter element 1 during use can be ensured. The metal sintered felt filter element 1 is wrapped by the cylinder frame 4, the connecting sleeve 5 and the connecting cover 6, thereby improving the protection of the metal sintered felt filter element 1 during transportation and use. The lifting handle 10 facilitates the carrying or placement of the metal sintered felt filter element 1, thereby improving the convenience of using the metal sintered felt filter element 1.

[0026] See Figure 4-Figure 6 , it is further obtained that a socket 13 is provided on the cylinder frame 4 for plugging into the connecting rod 11, a fixing hole 12 is provided on the connecting rod 11, and a slot 14 is provided on the side of the connecting sleeve 5 close to the metal sintered felt filter element 1 for plugging into the connecting rod 11, and a card slot 18 is provided in the slot 14, and a cylinder 15 is fixedly embedded on the connecting sleeve 5, and a slider 16 is slidably connected to the cylinder 15. A card rod 17 is fixedly provided on one side of the slider 16, and the card rod 17 slides through the cylinder 15 and passes through the fixing hole 12 to be engaged with the card slot 18, and a guide rod 19 is fixedly provided on the other side of the slider 16, and a spring 20 is sleeved on the guide rod 19, and the spring 20 is fixedly arranged between the slider 16 and the cylinder 15, and the end of the guide rod 19 away from the slider 16 slides through the cylinder 15 and extends to the outer end of the cylinder 15, and the end of the guide rod 19 away from the slider 16 is fixedly provided with a limit block 21, and a pull ring 22 is fixedly provided on the limit block 21.

[0027] The pull ring 22 is pulled outwards to disengage the clamping rod 17 from the clamping slot 18 and the fixing hole 12, and then the connecting rod 11 is pulled out by the handle 10, and then the cylinder frame 4 is removed from the metal sintered felt filter element 1, so that the metal sintered felt filter element 1 is exposed, and the metal sintered felt filter element 1 can be repaired.
