Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example, refer to Figures 1-6A valve structure with a filtering function includes a valve structure 1, which includes a valve 100. The valve 100 has an inlet pipe 101 and an outlet pipe 102 on its side wall. The inlet pipe 101 has an installation ring 6. The side wall of the installation ring 6 has four sets of positioning holes 7. The side wall of the installation ring 6 has a filter screen 5. The filter screen 5 is arranged in a semi-circular arch shape. The filter screen 5 has a reinforcing rib group 4. The reinforcing rib group 4 includes a first reinforcing rib 400 in the filter screen 5. The side wall of the first reinforcing rib 400 has three sets of second reinforcing ribs 401. The inner wall of the inlet pipe 101 has an abutment ring 2. The side wall of the abutment ring 2 has four sets of positioning pins 3 that are inserted into the positioning holes 7. The positioning pins 3 have cavities 8 inside. The cavities 8 have positioning mechanisms 9.

[0025] The positioning mechanism 9 includes a connecting block 902 that slides inside the cavity 8, an abutment plate 900 on the side wall of the connecting block 902, an opening 901 on the side wall of the positioning post 3 that cooperates with the abutment plate 900, a telescopic rod 903 on the inner side wall of the cavity 8, one end of the telescopic rod 903 being connected to the side wall of the connecting block 902, a first spring 904 being sleeved on the outer wall of the telescopic rod 903, and a limiting mechanism 11 on the top of the connecting block 902.

[0026] It should be noted that when the positioning hole 7 is engaged with the positioning post 3, the mounting ring 6 contacts the abutment ring 2. Under the action of the limiting mechanism 11, the abutment plate 900 can be moved. Under the action of the first spring 904, the abutment plate 900 can be moved out of the cavity 8, so that the abutment plate 900 can abut against the mounting ring 6 and ensure that it is fixed on the abutment ring 2.

[0027] The limiting mechanism 11 includes a sleeve 1104 at the top of the connecting block 902, a movable plate 1102 slidably disposed inside the sleeve 1104, a second spring 1103 at the bottom of the movable plate 1102, one end of the second spring 1103 being connected to the bottom of the sleeve 1104, a sliding post 1101 at the top of the movable plate 1102, a limiting plate 1100 on the outside of the positioning post 3, and one end of the sliding post 1101 penetrating the top of the sleeve 1104 and being connected to the limiting plate 1100.

[0028] It should be noted that: it can move the movable block 902, and at the same time, it can limit the movable block 902 after it moves to prevent it from moving.

[0029] The side wall of the positioning column 3 is provided with a sliding groove 10, and the sliding column 1101 slides in the sliding groove 10.

[0030] It should be noted that the sliding column 1101 can drive the connecting block 902 to move under the action of the sliding groove 10.

[0031] The side wall of the positioning column 3 is provided with two sets of limiting grooves 12, which are connected to the sliding groove 10. The limiting plate 1100 cooperates with the limiting grooves 12.

[0032] It should be noted that, with the cooperation of the limiting plate 1100 and the limiting groove 12, the sleeve 1104 and the sliding column 1101 can be limited without moving the connecting block 902, thus preventing them from moving.

[0033] The first reinforcing rib 400 is arranged in a ring shape, and its sidewall is connected to the inner sidewall of the mounting ring 6. The second reinforcing rib 401 is arranged in an arc-shaped strip, and the three sets of second reinforcing ribs 401 are arranged in a ring shape on the sidewall of the first reinforcing rib 400.

[0034] It should be noted that the second reinforcing rib 401 is in contact with the inner wall of the filter screen 5 and can support the filter screen 5. Thus, under the action of the first reinforcing rib 400 and the second reinforcing rib 401, the filter screen 5 can be supported, thereby further improving the impact resistance of the filter screen 5.

[0035] The working principle of this valve structure with filtering function is as follows: In the initial state, the abutment plate 900 is located in the cavity 8 (at this time, the first spring 904 is in a compressed state). The mounting ring 6 is abutted against the abutment ring 2 using the positioning hole 7. Then, the operator pulls the limiting plate 1100 to move out of the limiting groove 12. The limiting plate 1100 drives the movable plate 1102 and the sliding column 1101 to move upward. The movable plate 1102 stretches the second spring 1103. At this time, the sliding column 1101 is in the slide groove 10. Then, under the action of the elastic force of the first spring 904, the moving block 902 and the abutment plate 900 move, and the abutment plate 900 moves out of the opening 901. The mounting ring 6 is abutted to fix it, and then the limiting plate 1100 is released. Under the action of the second spring 1103, the limiting plate 1100 is driven to return to the limiting groove 12, which can limit the sleeve 1104 and the sliding column 1101 to prevent them from moving. When the water flows through the water inlet pipe 101, under the action of the semi-circular arched filter screen 5, the curved structure is used to convert the water flow impact into radial pressure, reducing the impact force of the water flow on the filter screen 5. Under the action of the first reinforcing rib 400 and the second reinforcing rib 401, the filter screen 5 can be supported, thereby further improving the impact resistance of the filter screen 5.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
