[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: an angle valve with a filtering function, including a valve tube 1, which is composed of a vertical tube and a horizontal tube connected together, with the vertical tube and the horizontal tube being integrated to make the interior interconnected, and the vertical tube and the horizontal tube being vertically distributed. External threads are provided on the outer sides of the vertical tube and the horizontal tube at points far apart from each other. A valve core 3 is provided inside the valve tube 1, and a knob 2 connected to the valve core 3 is provided on the top of the valve tube 1. A fixing plate 5 is fixedly connected inside the vertical tube, and the fixing plate 5 is tightly attached to the bottom of the valve core 3. An opening is provided on the fixing plate 5. The valve core 3 includes a cylinder 301, and two symmetrically arranged rectangular grooves are provided on the side wall of the cylinder 301. A movable plate 303 and a bottom plate 302 are provided inside the cylinder 301. The bottom plate 302 is located below the movable plate 303 and is fixedly connected to the cylinder 301. The bottom plate 302 and the movable plate 303 are connected to each other. Two symmetrically arranged fan-shaped slots are opened on the cylinder 301. A connecting rod 304 is movably connected inside the cylinder 301. A through hole is provided at the top of the vertical tube. The top of the connecting rod 304 extends through the through hole to the outside of the valve tube 1 and is fixedly connected to the knob 2 by a screw. The top and bottom of the knob 2 are provided with insertion holes, and a through hole is connected between the insertion holes. The top of the connecting rod 304 is inserted into the adjacent insertion hole, and the top of the connecting rod 304 is provided with a threaded hole that matches the screw. The bottom of the connecting rod 304 passes through the movable plate 303 and is movably connected to the bottom of the cylinder 301. A filter cartridge 4 is sleeved on the outside of the cylinder 301. The filter cartridge 4 is composed of a fixed tube 401 and filter paper 402. The fixed tube 401 is sleeved on the outside of the cylinder 301, and a first annular groove is provided on the periphery of the fixed tube 401. The filter paper 402 is located in the first groove.

[0021] According to the overall structure of the device, during use, the valve core 3 is installed into the valve tube 1, the connecting block 7 is threadedly connected to the vertical pipe and tightened. Then, the valve tube 1 is connected and fixed to the liquid delivery pipeline through the external thread. Turn the knob 2, and the knob 2 drives the movable plate 303 to rotate through the connecting rod 304, so that the movable plate 303 is aligned with the fan-shaped groove on the bottom plate 302, thereby making the inside of the cylinder 301 connected to the inside of the vertical pipe, allowing the liquid to flow. After the liquid enters the cylinder 301, it flows into the filter cartridge 4 from the rectangular groove on the cylinder 301. After being filtered by the filter paper 402, it flows to the outside of the filter cartridge 4 and enters the horizontal pipe, thus completing the filtration of the liquid. Turn the knob 2 in the opposite direction to make the fan-shaped groove misaligned, which can close the cylinder 301 and stop the liquid delivery. After long-term use, the top cover 6 can be unscrewed, the valve core 3 can be taken out, and the filter paper 402 can be replaced.

[0022] like Figure 4 As shown, the filter paper 402 is folded continuously in the horizontal direction and is connected end to end around the fixed tube 401. The filter paper 402 has a cylindrical metal mesh 404 on both the inner and outer sides. The fixed tube 401 is fitted with a sleeve 403 on the outside, and the sleeve 403 has a second slot aligned with the filter paper 402. The two metal meshes 404 are fixedly connected in the first slot and the second slot, respectively.

[0023] Continuous folding increases the contact area between the filter paper 402 and the liquid, accelerating the liquid's passage and thus improving filtration efficiency. The metal mesh 404 can fix the filter paper 402 within the first and second slots, and it can also perform preliminary filtration of larger impurities, further enhancing the filtration effect.

[0024] like Figure 4 As shown, the fixed tube 401 has an external thread on its periphery, and the sleeve 403 has an internal thread that matches the external thread on its inner wall. The fixed tube 401 is fixedly connected to a first sealing ring 405 near the top and bottom, which is in close contact with the inner wall of the sleeve 403.

[0025] The threaded connection between the fixed tube 401 and the sleeve 403 facilitates the separation of the fixed tube 401 and the sleeve 403, thereby making it easier to replace the filter paper 402 without replacing the entire filter cartridge 4, reducing maintenance costs. At the same time, the first sealing ring 405 seals the gap between the fixed tube 401 and the sleeve 403.

[0026] like Figure 2 As shown, the top of the vertical pipe is open, and a top cover 6 is provided at the opening. The top and bottom of the top cover 6 are integrally connected with a hexagonal block and a connecting block 7, respectively. A through hole is provided on the top cover 6 from top to bottom, and the connecting block 7 is threaded into the vertical pipe. The cylinder 301 is fixedly connected to the bottom of the connecting block 7.

[0027] The threaded connection between the connecting block 7 and the vertical pipe facilitates the disassembly of the top cover 6, thereby making it easier to remove the cylinder 301 and the filter cartridge 4 from the valve pipe 1. This facilitates the maintenance of the valve core 3 and the replacement of the filter cartridge 4. The hexagonal block can be used with commonly used wrenches and other tools, making it easy to tighten the top cover 6.

[0028] like Figure 2 , 3 As shown, a sealing gasket 9 is fixedly connected to the top of the fixed plate 5. The bottom of the cylinder 301 and the filter cylinder 4 are both in close contact with the sealing gasket 9. A sealing gasket 9 is fixedly connected to the top of the bottom plate 302. A fan-shaped groove is provided on the sealing gasket 9. An annular groove is provided on the outer periphery of the connecting block 7 and the inner wall of the perforation. A second sealing ring 8 is provided in the annular groove. The connecting rod 304 passes through the second sealing ring 8 in the perforation.

[0029] The sealing gasket 9 seals the interior of the cylinder 301 and the exterior of the filter cartridge 4 to prevent liquid from flowing through the gap between the cylinder 301 and the fixed plate 5. The sealing gasket 9 also seals the spacers on the movable plate 303 and the bottom plate 302 when they are misaligned. The second sealing ring 8 seals the spacers between the top cover 6 and the vertical pipe, and between the connecting rod 304 and the perforation to prevent liquid from leaking from the top opening of the vertical pipe and the perforation during use.

[0030] Working principle: When in use, insert the valve core 3 into the valve tube 1, connect the connecting block 7 to the vertical pipe threadedly, and tighten it. Then, connect and fix the valve tube 1 to the liquid delivery pipeline through the external thread. Turn the knob 2, and the knob 2 drives the movable plate 303 to rotate through the connecting rod 304, so that the movable plate 303 is aligned with the fan-shaped groove on the bottom plate 302, thereby making the inside of the cylinder 301 connected to the inside of the vertical pipe, allowing the liquid to flow. After the liquid enters the cylinder 301, it flows into the filter cartridge 4 from the rectangular groove on the cylinder 301. After being filtered by the filter paper 402, it flows to the outside of the filter cartridge 4 and enters the horizontal pipe, thus completing the filtration of the liquid. Turn the knob 2 in the opposite direction to make the fan-shaped groove misaligned, which can close the cylinder 301 and stop the liquid delivery. After long-term use, the top cover 6 can be unscrewed, the valve core 3 can be taken out, and the filter paper 402 can be replaced.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
