[ detailed description ] embodiments

Example 1

Referring to fig. 2 to 4, the utility model relates to a can eliminate out water control valve of hanging water, including valve body 10, pilot valve control assembly 20 and faucet subassembly 30, water inlet chamber 101 and play water chamber 102 have in the valve body 10, be equipped with the water inlet 103 that is linked together with water inlet chamber 101 on the valve body 10, be equipped with pilot valve control assembly 20 between water inlet chamber 101 and the play water chamber 102, the water inlet end of faucet subassembly 30 the play water end of pilot valve control assembly 20 is linked together with play water chamber 102, the play water end of pilot valve control assembly 20 is equipped with the resorption structure, the resorption structure produces one after pilot valve control assembly 20 closes will the negative pressure of the inside residual water of faucet subassembly 30 upwards suction.

Further, referring to fig. 4, the suck-back structure comprises a venturi tube 1 and a negative pressure cavity 2, an inlet 11 of the venturi tube 1 is connected to a water outlet end of the pilot valve control assembly 20, an outlet 12 of the venturi tube 1 is connected to a water outlet nozzle assembly 30, and a negative pressure port 13 of the venturi tube 1 is communicated with the negative pressure cavity 2. In this embodiment, the inlet 11 of the venturi tube 1 is formed by extending the outer wall of the water outlet chamber 102 downward, the outlet 12 of the venturi tube 1 is partially formed by the inlet of the water outlet nozzle assembly 30, and the negative pressure port 13 of the venturi tube 1 is formed by the gap between the inlet end of the water outlet nozzle assembly 30 and the outlet end of the water outlet chamber 102.

Further, referring to fig. 4, the lower portion of the valve body 10 has a suck-back pipe 104, the suck-back pipe 104 is sleeved on the periphery of the venturi tube 1, and the negative pressure cavity 2 is arranged between the suck-back pipe 104 and the venturi tube 1. The suck back conduit 104 may be made of a rigid material or an elastic material. When the suck-back pipe 104 is made of elastic material, the deformation amount is larger, and the generated negative pressure effect is better.

Further, the nozzle assembly 30 is installed below the suck-back pipe 104, and a sealing ring is disposed between the nozzle assembly and the suck-back pipe. In this embodiment, the inlet end of the water outlet nozzle assembly 30 has a first tapered surface, the outlet end of the water outlet chamber 102 has a second tapered surface, the first tapered surface is sleeved outside the second tapered surface, the large diameter end of the first tapered surface and the large diameter end of the second tapered surface are both facing the negative pressure chamber 2, and the negative pressure port 13 of the venturi tube 1 is formed by a gap between the first tapered surface and the second tapered surface.

The working principle of the embodiment is as follows: through setting up venturi 1 at the play water end of pilot valve control assembly 20, can produce the venturi negative pressure effect after closing pilot valve control assembly 20 to produce the negative pressure in negative pressure chamber 2, can upwards aspirate the certain distance with the inside residual water of faucet subassembly 30, thereby eliminate the faucet subassembly "hang water" phenomenon.

Example 2

Referring to fig. 5 to 7, the present embodiment is different from embodiment 1 in that a suck-back structure is adopted. In this embodiment, hang-up is eliminated by the elongated spout assembly 30.
