The water stop pad 120 is integrally formed, and includes a water stop main body 121 and an extension portion 122, wherein the extension portion 122 extends outward from the water stop main body to form an anti-siphon pad matched with the anti-siphon hole. Specifically, the water stop main body 121 is provided with an annular groove, the support frame 130 is provided with a convex ring matched with the annular groove, and the annular groove is sleeved on the convex ring to support the water stop pad 120 on the support. The valve core 110 is T-shaped.

Example two

Referring to fig. 3 to 7, a water inlet valve includes a valve housing 400, a valve cover 300, an inner core tube 200, a water-stop assembly 100 and a switch assembly 500, wherein the valve cover 300 is fastened to the valve housing 400, the inner core tube 200 is disposed in the valve housing 400, the inner core tube 200 is provided with a water inlet channel and a water outlet 221, a water outlet channel is formed between an outer wall of the inner core tube 200 and an inner wall of the valve housing 400, the water-stop assembly 100 is disposed between the inner core tube 200 and the valve cover 300, in the embodiment, the water-stop assembly 100 is the water-stop assembly 100 of the first embodiment, a support frame 130 is erected at an upper end of the inner core tube 200, a water-stop main body 121 and the valve cover 300 are matched to form a back pressure cavity, a gap between the valve rod and a wall of a through hole communicates the water inlet channel and the back pressure cavity, the valve cover 300 is provided with a vent hole 310 communicating with the back pressure cavity and a siphon hole 320 communicating with the water outlet channel, a siphon hole 320 is formed in the extension portion 122 and is disposed corresponding to block or open the siphon hole 320, the switch assembly 500 blocks or opens the vent hole 310 according to the water tank level. When water is supplied, the anti-siphon pad formed by the extension portion 122 is pressed against the valve cover 300 by the water flow from the water supply passage to close the anti-siphon hole 320.

Specifically, the lower end of the inner core tube 200 is a hollow circular tube 210, the upper end is a disc 220 provided with a middle through hole and a water outlet 221, two circles of convex rings are arranged on the disc 220, the upper ends of the two circles of convex rings from inside to outside respectively form a water stop surface 222 and an anti-siphon surface 223, the water outlet 221 is arranged at the outer end of the disc 220, and the anti-siphon surface 223 is positioned between the water stop surface 222 and the water outlet 221; when water is stopped, the water stopping body 121 is attached to the water stopping surface 222 to cut off the communication between the water inlet passage and the water outlet passage, and the anti-siphon pad formed by the extension part 122 can be attached to the anti-siphon surface 223 to cut off the communication between the anti-siphon hole 320 and the water inlet passage.

Please refer to fig. 6, during anti-siphon: firstly, when water is normally stopped, the switch assembly 500 blocks the vent hole 310, water flow of the water inlet channel enters the backpressure cavity through a gap between the valve rod and the wall of the through hole, the water stopping main body 121 is pressed by water pressure in the backpressure cavity to move downwards to prop against the water stopping surface 222, communication between the water inlet channel and the water outlet channel is cut off, and water flow in the water inlet channel cannot flow to the water outlet channel and cannot flow to the anti-siphon pad formed by the extension part 122; when the water is cut off or the water pressure in the water inlet channel is too low due to other reasons, the anti-siphon cushion is not pressed by the water flow from the water inlet channel. Therefore, when water is normally stopped or the water pressure in the water inlet channel is too low due to other reasons, the water stopping component plays a role in preventing siphoning, the anti-siphoning pad cannot be attached to the anti-siphoning hole 320, and air can enter the water outlet channel through the anti-siphoning hole 320 to prevent siphoning; meanwhile, the anti-siphon pad can be tightly attached to the anti-siphon surface 223 by air pressure so as to cut off the communication between the outside and the water inlet channel and prevent water flow from flowing back to the water inlet channel.

Referring to fig. 7, when water enters normally, the switch assembly 500 opens the vent hole 310, the water-stopping main body 121 moves upward under the pressure of water flow from the water inlet channel, the water-stopping main body 121 leaves the water-stopping surface 222, the communication between the water inlet channel and the water outlet channel is opened, the water flow flows into the water outlet channel from the water outlet 221, at this time, the anti-siphon pad is pressed by the water flow from the water inlet channel to cling to the anti-siphon hole 320, air cannot enter the water outlet channel through the anti-siphon hole 320, and the water flow cannot flow out through the anti-siphon hole 320.

The above description is only a preferred and practical embodiment of the present invention, and all equivalent changes to the description and claims of the present invention should be considered as included in the claims of the present invention.
