Referring to fig. 1 to 5, the water inlet valve with an air blocking function includes a back pressure switch 20 for opening or closing a waterway and a float 30, wherein the float 30 is in transmission connection with the back pressure switch 20 to drive the back pressure switch 20 to open or close the waterway. The principle that the float 30 controls the back pressure switch 20 to open or close the water path is in fact prior art. The water-stop valve further comprises a water-stop seat 40, a water inlet flow channel 42 extending transversely is arranged in the water-stop seat 40, and the back pressure switch 20 is arranged on the water-stop seat 40 and opens or closes the water outlet end of the water inlet flow channel 42. The water stop seat 40 is further provided with a water outlet channel 44, a water inlet end of the water outlet channel 44 is in butt joint with a water outlet end of the water inlet channel 42, and a water outlet end of the water outlet channel 44 is arranged at the top of the water stop seat 40. The floating barrel 30 is positioned below the water stop seat 40, the liquid level in the water tank is not higher than the floating barrel 30 and is always positioned below the water stop seat 40, the water level is far away from the water outlet end of the water outlet flow channel 44, and the air separation distance of at least more than 20mm exists.

When water enters, the floating barrel 30 falls down due to the low level of the water tank, the back pressure switch 20 opens the water inlet flow passage 42, and water flows out of the water outlet end at the top of the water stop seat 40 along the water inlet flow passage 42 and the water outlet flow passage 44 to enter the water tank. When the liquid level in the water tank rises to the required height, the floating barrel 30 rises to the set height, the back pressure switch 20 is driven to close the water inlet flow passage 42, and water inlet is stopped. In a static state, the liquid level in the water tank is below the water stopping seat 40, and a larger air separation interval exists between the liquid level in the water tank and the water outlet end at the top of the water stopping seat 40. In addition, the water inlet channel 42 of the water stopping seat 40 is directly butted with a water supply system, and the structure is simplified.

Preferably, the water collecting device further comprises a vertically arranged water collecting pipe 50, and an opening at the top end of the water collecting pipe 50 receives water discharged from the water outlet end of the water outlet channel 44; the top opening of the water receiving pipe 50 is positioned below the water stopping seat 40; an air separation section is formed between the water outlet end of the water outlet flow passage 44 and the opening at the top end of the water receiving pipe 50. Under the condition that the water receiving pipe 50 is not arranged, the water discharged from the water stopping seat 40 directly falls into the water tank and is beaten on the liquid level, the fall is large, and the noise is large. The water receiving pipe 50 is provided, so that splash can be effectively prevented, and noise can be isolated.

Preferably, a water outlet nozzle 46 is arranged at the water outlet end of the water outlet channel 44, and the water outlet nozzle 46 guides the water flow to one side of the water stop seat 40; the top end of the water receiving pipe 50 is biased to one side of the water stopping seat 40 and is positioned right below the water outlet nozzle 46. Therefore, the structure of the water inlet valve is more compact, the occupied volume is reduced, and the water inlet valve is convenient to install in a water tank. In this embodiment, the water outlet nozzle 46 is sleeved on the water outlet end and fastened to the outer wall of the water outlet end, and a sealing ring is disposed between the water outlet nozzle 46 and the outer wall of the water outlet end, so as to ensure the firmness of the connection between the water outlet nozzle 46 and the water stop seat 40.

Preferably, the top of the water receiving pipe 50 is plugged with the water stopping seat 40, so that the structure is more stable.

Preferably, the water receiving pipe further comprises a splitter 60, the splitter 60 is arranged in the water receiving pipe 50 and located at the top, and the splitter 60 is of a grid structure and is provided with a plurality of water leakage holes. Therefore, the fall of water flow can be greatly reduced, and the silencing effect is achieved.

Preferably, a diversion trench 62 is arranged on the diversion sheet 60, a water hole is arranged on the side wall of the water receiving pipe 50 corresponding to the diversion trench, a counterweight cavity 32 is arranged at the top of the floating bucket 30, the water flowing out of the water hole flows into the counterweight cavity 32, and a water leakage hole is arranged at the bottom of the counterweight cavity. When water enters, part of water is drained to the counterweight cavity 32, the weight of the floating bucket 30 is increased, after water is stopped, counterweight water flows into the water tank, the weight of the floating bucket 30 is reduced, the floating bucket 30 generates larger buoyancy force and can drive the back pressure switch 20 to stop water stably, and the situation that the back pressure switch 20 is opened accidentally due to fluctuation of the liquid level in the water tank is effectively avoided.

Preferably, the floating barrel 30 can move up and down to be sleeved on the water receiving pipe 50. The water receiving pipe 50 guides the lifting of the float 30. In the middle of this scheme, the keg float 30 sets up counter weight chamber 32, is single keg float structure, compares in the stagnant water cup with current structure keg float setting, has simplified the structure. Preferably, the back pressure switch 20 includes a water stop rubber gasket 22, a gland 24, and a swing hook 26, the gland 24 is connected to the side of the water stop seat 40, the water stop rubber gasket 22 is connected to the inner side of the gland 24, and a pressure water cavity 28 capable of communicating with the water inlet flow passage 42 is formed therebetween. The pressure relief hole 242 is formed in the gland 24, and the swing hook 26 is rotatably connected with the gland 24. A push rod 34 is arranged on the floating barrel 30, after the floating barrel 30 rises, one end of the swing hook 26 is lifted by the push rod 34, so that the swing hook 26 blocks the pressure relief hole 242, and after the pressure in the pressure water cavity 28 is increased, the water stop rubber pad 22 is driven to close the water path. After the water is drained and the floating bucket 30 falls down, the swing hook 26 resets to open the pressure relief hole 242, the water pressure of the water channel flushes the water stop rubber mat 22, and the water channel is opened for water inflow.

Preferably, the pressing cover 24 is screwed on the water stopping seat 40, and the pressing cover 24 is convenient to install. In particular, the pressing cover 24 is provided with an elastic buckle 244, the water stop seat 40 is provided with a stop arm 48, the rotation of the pressing cover 24 is limited when the elastic buckle 244 is abutted against the stop arm 48, and the pressing cover 24 can be rotatably dismounted after the elastic buckle 244 is broken, so that the dismounting and the mounting are convenient.

Preferably, the water inlet end of the water inlet channel 42 is provided with an external thread 422, and the external thread 422 can be directly screwed with the water tank, so that the assembly is simpler.
