[0019] The following further describes the present invention in conjunction with the drawings for specific embodiments:

[0020] As Figures 1-4As shown in the figure, an angle valve capable of filtering and quickly cleaning impurities includes a valve body 5 and a ball valve disposed inside the valve body 5. The valve body 5 is a three-way valve body, and the valve body 5 is provided with a water inlet 51, a water outlet 52, and a lower water outlet 53 that communicate with each other. The water outlet 52 and the water inlet 51 are coaxially arranged and face in opposite directions. The lower water outlet 53 is located below the valve body between the water inlet 51 and the water outlet 52 and forms a 90° angle with the valve body 5. The ball valve includes a first ball valve 7 and a second ball valve 10. The first ball valve 7 is disposed in the valve body between the water inlet 51 and the lower water outlet 53, and the second ball valve 10 is disposed in the valve body between the lower water outlet 53 and the water outlet 52. The first ball valve 7 and the second ball valve 10 are respectively controlled by a control handle assembly to close or open the corresponding water inlet 51 or water outlet 52. A cylindrical filter cartridge 9 is further provided between the first ball valve 7 and the second ball valve 10. One end of the filter cartridge 9 facing the first ball valve 7 is provided with a compression nut 8, and one end of the filter cartridge 9 facing the second ball valve 10 is provided with a limit nut 11. The filter cartridge 9 is located above the lower water outlet 53 and extends towards both sides of the valve body 5.

[0021] To improve the sealing effect, in this embodiment, sealing gaskets 6 are respectively provided on both sides of the first ball valve 7 and the second ball valve 10. A water outlet joint 13 is threadedly connected to the water outlet 53, and a sealing ring 12 is further provided between the water outlet joint 13 and the second ball valve 10. The sealing ring 12 is tightly attached to the sealing gasket 6.

[0022] As an implementation manner, both ball valves are provided with a diversion hole passing through the center of the ball. The control handle assembly includes a rotating shaft 4, a sealing gasket 3, a screw 2, and a control handle 1. One end of the rotating shaft 4 is connected to the ball valve, and the other end of the rotating shaft 4 extends outwards through the valve body and is connected to the control handle 1 by a screw 2. The sealing gasket 3 is sleeved on the screw 2. During use, the ball valve is rotated by rotating the control handle 1.

[0023] In this embodiment, a positioning groove is provided on one side of the ball valve connected to the rotating shaft 4, and one end of the rotating shaft 4 connected to the ball valve is inserted into the positioning groove and is snap-fitted therewith.

[0024] One end of the rotating shaft 4 connected to the ball valve has a flat position, and one end of the rotating shaft 4 connected to the control handle 1 also has a flat position, and is matched with the slot on the control handle 1 through this flat position.

[0025] As an implementation manner, one end of the control handle 1 close to the valve body 5 has a limit protrusion, and a positioning rib is correspondingly provided on the valve body 5. The limit protrusion is matched with the positioning rib.

[0026] Furthermore, it further includes a decorative cover 14. The decorative cover 14 is sleeved on the outer peripheral surface of the water inlet 51 and is used for connecting the angle valve and the wall where the external water inlet pipe is located.

[0027] Now, the specific use scenario will be further described. In this embodiment, the lower water outlet 53 of the angle valve is connected to the washing machine water inlet pipe on the balcony for illustration. After the valve body 5 is installed, when inFigure 3 In the normal use mode, the diversion hole of the first ball valve 7 is communicated with the flow channel of the valve body. Water enters the filter cartridge from the water inlet 51 through the diversion hole of the first ball valve 7. After being filtered by the filter cartridge, the water enters the washing machine through the lower water outlet 53. At this time, since the diversion hole of the second ball valve 10 is not communicated with the flow channel of the valve body 5, the water outlet 52 is in a closed state, and all the filtered water flows out through the lower water outlet 53. In this mode, the water inlet and the lower water outlet form an asymmetric flow channel pressure compensation design, which can maintain a stable water pressure output. When the control handle 1 of the second ball valve 10 is rotated 90 degrees, the second ball valve 10 is communicated with the valve body 5. At this time, it is in the flushing mode, and this mode can be used to conveniently flush the impurities in the filter cartridge to realize the function of automatic sewage discharge without disassembly.

[0028] As an implementation manner, an arrow indicating the water outlet direction is also recessed on the control handle 1, which is more convenient for the operator to use.
