[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, the angle valve comprises a valve body 1, wherein the valve body 1 is provided with a water passage for passing water, and a valve core 2 for controlling the flow of liquid is provided in the valve body 1 and relative to the water passage, and the valve body 1 is provided with a water outlet 3 for discharging water, and a filter 4 is provided at the water outlet 3, and the filter 4 is fixedly connected to the water outlet 3 by a thread, and a water hole 5 for passing water is opened at the front end of the water outlet 3, and a filter 6 is provided in the water hole 5, and the front end of the filter 4 is a trapezoidal structure, and is consistent with the cross section of the water outlet 3, and the filter A check assembly 7 for double check is provided in the member 4, and the check assembly 7 includes a check member 1 8, a sliding rod 1 9 and a check member 2 10. A fixing portion 11 is fixedly provided in the filter member 4, and a water hole 5 for passing water is provided on the fixing portion 11. The check member 1 8 and the sliding rod 1 9 are provided at the front end of the fixing portion 11 and are used to close the water hole 5 at the front end of the filter member 4. A fixing seat 12 is provided at the rear end of the fixing portion 11, and the check member 2 10 slides on the fixing seat 12. A reset spring 13 is provided between the fixing seat 12 and the check member 2 10.

[0013] To explain in further detail, the valve core 2 is opened to allow the water flow channel inside the angle valve to circulate, and the liquid flows from the water flow channel into the water outlet part 3 to discharge the water, and is filtered through the filter element 4 in the water outlet part 3. Pressure is applied to the check piece 1 8, and the reset spring 13 there is in a compressed state. The water flow hole 5 at the front end of the filter element 4 is in a flow state. When pressure is applied to the check piece 2 10, the reset spring 13 at the rear end of the check piece 2 10 is compressed, so that the water flow hole 5 of the fixed part 11 is in a flow state. Finally, the liquid flows out from the water outlet part 3. When the valve core 2 is in a closed state, the two reset springs 13 rebound, and the end face of the check piece 1 8 abuts against the front end of the filter element 4, closing the water flow hole 5 at the front end of the filter element 4. The end face of the check piece 2 10 abuts against the fixed part 11, closing the water flow hole 5 of the fixed part 11, so that the angle valve has a double check effect.

[0014] To be more specific, one end of the sliding rod 9 is connected to the check member 8, and the other end of the sliding rod 9 extends into the fixed portion 11 and slides in the fixed portion 11. A return spring 13 is provided between the fixed portion 11 and the sliding rod 9.

[0015] To be more specific, the water outlet portion 3 and the valve body 1 are integrally formed, and the water outlet portion 3 and the valve body 1 are arranged at a 90-degree angle.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0017] Although this document frequently uses terms such as valve body 1, valve core 2, water outlet 3, filter element 4, water hole 5, filter screen 6, check assembly 7, check element 1, sliding rod 1 9, check element 2 10, fixing portion 11, fixing seat 12, and return spring 13, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
