In order to facilitate the storage of the limit pin 54 and reduce the possibility of the loss of the limit pin 54, a boss 56 is formed on one side of the connecting seat 5, which faces away from the valve cover 4, three placing holes 57 with the same diameter as the locking hole 55 are formed in the boss 56, and when the limit pin 54 is taken down from the locking hole 55, the limit pin can be inserted into the placing holes 57 for temporary storage.

Referring to fig. 2, a connecting cylinder 42 is formed on the inner wall of the valve cap 4 on the side close to the filter cartridge 3, the connecting cylinder 42 is coaxial with the valve cap 4, the diameter of the connecting cylinder 42 is slightly smaller than that of the filter cartridge 3, and the connecting cylinder 42 is in inserted fit with the filter cartridge 3. The connecting cylinder 42 is sleeved with a sealing ring 43, one end of the sealing ring 43 is in a circular sleeve shape and is extruded between the inner wall of the filter cylinder 3 and the outer wall of the connecting cylinder 42, and the other end is in a circular ring shape and is positioned at the end part of the filter cylinder 3 and is abutted against the cylinder opening of the filter cylinder 3.

Referring to fig. 2, the clamping block 41 is clamped with the clamping groove 52, the connecting cylinder 42 is inserted into the filter cylinder 3, the sealing ring 43 is extruded by the filter cylinder 3 and the connecting cylinder 42, the sealing ring 43 deforms under stress to fill the gap between the connecting cylinder 42 and the filter cylinder 3, and the end of the sealing ring 43 outside the filter cylinder 3 deforms to plug the cylinder opening of the filter cylinder 3, so that the sealing performance of the filter cylinder 3 is improved.

Referring to fig. 2, a tight-abutting plate 44 is fixedly sleeved on the connecting cylinder 42, the tight-abutting plate 44 is located in the valve cover 4, and when the connecting cylinder 42 is inserted into the filter cartridge 3, the tight-abutting plate 44 is pressed on one end of the sealing ring 43 outside the filter cartridge 3, so that the sealing ring 43 is further deformed, and the sealing performance of the cartridge opening of the filter cartridge 3 is improved.

The implementation principle of the pipe filter convenient to disassemble and assemble in the embodiment of the application is as follows: the valve cover 4 is aligned with the filter cartridge 3 and pressed against the filter cartridge 3, and in this process, the snap-in blocks 41 fall between the adjacent two connecting blocks 51. The valve cover 4 is rotated to enable the clamping block 41 to slide into the clamping groove 52 until the clamping block abuts against the baffle plate 53, and then the limit pin 54 is inserted to stably connect the valve cover 4 with the filter cartridge 3. The connecting cylinder 42 is inserted into the filter cylinder 3, the filter cylinder 3 and the connecting cylinder 42 extrude the sealing ring 43, the sealing ring 43 deforms under stress to fill the gap between the connecting cylinder 42 and the filter cylinder 3, and the sealing ring 43 deforms to plug the cylinder opening of the filter cylinder 3 under the extrusion of the abutting plate 44 and the cylinder opening of the filter cylinder 3 at the outer end of the filter cylinder 3. When the valve cover 4 needs to be disassembled, the limiting pin 54 is pulled out, the valve cover 4 is rotated reversely, and then the valve cover 4 is taken down and inserted into the placing hole 57 for temporary storage.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
