DETAILED DESCRIPTION OF THE EMBODIMENTS
The present disclosure is further described in detail below in combination with the accompanying drawings and specific embodiments:
As shown in FIG. 1-FIG. 20, an angle valve structure includes a angle valve body 1. A water inlet channel 11 and a water outlet channel 12 are arranged in the angle valve body 1. Between the water inlet channel 11 and the water outlet channel 12, an accommodation cavity 13 communicated with the water inlet channel 11 and the water outlet channel 12 respectively is also arranged. A valve core 2 is rotatably arranged in the accommodation cavity 13, a knob 3 is fixedly connected to one end of the valve core 2 exposed outside the accommodation cavity 13, and a sealing block 4 for sealing the water outlet channel 12 when sealing is arranged on the valve core 2. The valve core 2 includes a main body part 21 and an elastic arm 22 connected with the main body part 21 at one end, and a mounting groove 24 for placing the sealing block 4 is arranged on one side of the main body part 21. One side of the elastic arm 22 is provided with an extrusion portion 221, and the other side of the elastic arm 22 is provided with a contact portion 222 which extends into the mounting groove 24 and butts against the sealing block 4 after assembly. When the angle valve is closed, the extrusion portion 221 butts against the inner wall of the accommodation cavity 13, so that under the action of the inner wall of the accommodation cavity 13, the contact portion 222 butts the sealing block 4 against the water outlet channel 12 to complete the sealing. When the angle valve is opened, the extrusion portion 221 butts against the inner wall of the accommodation cavity 13, so that the contact portion 222 butts the sealing block 4 against the inner wall of the accommodation cavity 13. The other side of the main body part 21 is provided with an accommodation slot 23, the bottom wall of the mounting slot 24 is provided with an opening slot 241, so that the accommodation slot 23 is communicated with the mounting slot 24 through the opening slot 241. One end of the elastic arm 22 is fixedly connected with the bottom wall of the accommodation slot 23, and the contact portion 222 is inserted in the opening slot 241 and butts against the sealing block 4 after assembly. The extrusion portion 221 is provided with a wear-resistant block 223, so that the extrusion portion 221 butts against the inner wall of the accommodation cavity 13 through the wear-resistant block 223 after assembly. One end of the elastic arm 22 is also provided with a reinforcing rib 224. After assembly, the elastic arm 22 swings towards one side of the sealing block 4 under the action of the inner wall of the accommodation cavity 13 or under the action of water, so that the contact portion 222 or water butts the sealing block 4 against the water outlet channel 12 to complete the sealing. By using the pressure of water and the force of the contact portion 222, the sealing effect is strengthen, so as to effectively prevent water leakage. When in use, only the wear-resistant block 223 is in contact with the inner wall of the accommodation cavity 13, so that after long-term use of the angle valve, only the wear-resistant block 223 of the valve core 2 is worn. At the same time, the wear of the wear-resistant block 223 will not reduce the sealing performance of the sealing block 4, the wear-resistant block 223 is still against the inner wall of the accommodation cavity 13, and the contact portion 222 will still press the sealing block 4 against the water outlet channel 12, so as to maintain the sealing connection and effectively prevent water leakage.
As shown in FIG. 4-FIG. 6 and FIG. 15-FIG. 16, in this embodiment, one end of the main body part 21 is provided with a first rotating part 25, the other end of the main body part 21 is provided with a second rotating part 26. After assembly, a water flow channel 29 for water flow is arranged between the first rotating part 25, the second rotating part 26, the main body part 21 and the inner wall of the accommodation cavity 13. When the knob 3 is rotated, so that the valve core 2 drives the sealing block 4 to move and no longer butts against the water outlet channel 12, water can enter the accommodation cavity 13 from the water inlet channel 11 and flow into the water outlet channel 12 through the water flow channel 29. At the same time, the knob 3 can be rotated to control the area occupied by the sealing block 4 on the water outlet channel 12, so that the flow of water flow can be regulated, and the structure is simple and easy to disassemble.

After assembly, the limit column 272 is movably arranged in the arc groove 141. When the limit column 272 is against the closed limit step 142, the sealing block 4 is against the water outlet channel 12 to complete the sealing. When the limit column 272 is against the open limit step 143, the sealing block 4 is removed from the water outlet channel 12. The limit column 272 is not only used to prevent the relative rotation between the valve core 2 and the knob 3 after assembly, but also configured for positioning, so as to prevent the user from not knowing whether the sealing block 4 has been against the water outlet channel 12 when the angle valve is closed. When the limit column 272 butts against the closed limit step 142, the sealing block 4 butts against the water outlet channel 12 to complete the sealing, and the angle valve is in the closed state at this time. When the limit column 272 butts against the open limit step 143, the sealing block 4 is removed from the water outlet channel 12, so that water can enter into the accommodation cavity 13 from the water inlet channel 11 and flow into the water outlet channel 12 through the water flow channel 29, at this moment, the angle valve is in the open state.
