[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figure 1-4As shown, an angle valve capable of filtering and quickly cleaning impurities includes a valve body 5 and a ball valve disposed within the valve body 5. The valve body 5 is a three-way valve body, and the valve body 5 is provided with an inlet 51, an outlet 52, and a lower outlet 53 that are interconnected. The outlet 52 and the inlet 51 are coaxially arranged and face opposite directions. The lower outlet 53 is located below the valve body between the inlet 51 and the 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 inlet 51 and the lower outlet 53, and the second ball valve 10 is disposed in the valve body between the lower outlet 53 and the outlet 52. The first ball valve 7 and the second ball valve 10 are controlled by a control handle assembly, thereby closing or opening the corresponding inlet 51 or outlet 52. A cylindrical filter cylinder 9 is provided between the first ball valve 7 and the second ball valve 10. A clamping nut 8 is provided at the end of the filter cylinder 9 facing the first ball valve 7, and a limiting nut 11 is provided at the end of the filter cylinder 9 facing the second ball valve 10. The filter cylinder 9 is located above the lower outlet 53 and extends to 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 connector 13 is threaded onto the water outlet 53, and a sealing ring 12 is also provided between the water outlet connector 13 and the second ball valve 10, with the sealing ring 12 tightly attached to the sealing gasket 6.

[0022] In one implementation, both ball valves are provided with a flow guide hole that penetrates the ball core. The control handle assembly includes a rotating shaft 4, a sealing washer 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 outward through the valve body and is connected to the control handle 1 by the screw 2. The sealing washer 3 is fitted on the screw 2. When in 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 connecting shaft 4, and the end of the shaft 4 connected to the ball valve is inserted into the positioning groove and engaged with it.

[0024] The end of the rotating shaft 4 connected to the ball valve has a flat part, and the end of the rotating shaft 4 connected to the control handle 1 also has a flat part, which engages with the slot on the control handle 1 through the flat part.

[0025] In one embodiment, the control handle 1 has a limiting protrusion at one end near the valve body 5, and the valve body 5 is provided with a corresponding positioning rib, with the limiting protrusion cooperating with the positioning rib.

[0026] Furthermore, it also includes a decorative cover 14, which is fitted onto the outer periphery of the inlet 51 and is used for connecting the angle valve and the wall where the external inlet pipe is located.

[0027] The following is a further explanation of the specific usage scenario. This embodiment uses the lower outlet 53 of the angle valve connected to the water inlet pipe of the washing machine on the balcony as an example. After the valve body 5 is installed, when it is in the... Figure 3 In normal operating mode, the guide hole of the first ball valve 7 is connected to the flow channel of the valve body. Water enters the filter cartridge from the inlet 51 through the guide hole of the first ball valve 7. After being filtered by the filter cartridge, the water enters the washing machine through the lower outlet 53. At this time, since the guide hole of the second ball valve 10 is not connected to the flow channel of the valve body 5, the outlet 52 is closed, and all the filtered water flows out through the lower outlet 53. In this mode, the inlet and the lower outlet form an asymmetrical 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 connected to the valve body 5. At this time, it is in the flushing mode. This mode can be used to easily flush the impurities in the filter cartridge and realize the automatic sewage discharge function without disassembly.

[0028] As one implementation, the control handle 9 is also recessed with an arrow indicating the direction of water flow, which makes it more convenient for the operator to use.

[0029] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent structural or procedural modifications made using this specification are included within the patent protection scope of this invention.
