Description

Technical Field

[0002] The kitchen faucet with a spray gun in the prior art generally includes a faucet body, a switching valve group, a hot water switch valve group, a cold water switch valve group and a spray gun. The faucet body includes two side seats and a transverse seat body connected between the two side seats, the hot water switch valve group and the cold water switch valve group are respectively arranged on the two side seats, and the switching valve group is arranged on the transverse seat body. The hot water switch valve group and the cold water switch valve group are connected to the switching valve group through a water pipe located in the transverse seat body. After the switching valve group receives the hot water from the hot water switch valve group and the cold water switch valve group, mixed water is formed. The switching valve group includes two upper and lower water outlets, the upper water outlet is connected to the water outlet elbow, and the lower water outlet is connected to the spray gun. The switching valve group can control the mixed water to be connected to the upper water outlet or the lower water outlet. However, for the existing kitchen faucet, the lower water outlet can only be arranged on the transverse seat body, which also leads to that when designing the overall shape of the kitchen faucet, it is necessary to consider how to hide the lower water outlet. The current design is to set up an additional panel, move the faucet body as a whole down to the countertop, and use the panel to cover the horizontal seat as a whole. The designer's design ideas are limited. For example, the horizontal body cannot be suspended in the air. Even if the horizontal body is suspended in the air, due to the existence of the lower water outlet, a covering panel column connected between the lower water outlet and the countertop needs to be designed. In this way, it looks like the horizontal seat of the kitchen faucet has three columns, and the design is not simple enough. Summary of the invention

[0042] In this embodiment, the switching valve group 2 includes a switching valve seat 23 arranged in the third valve chamber 133, and the first switching valve seat 31 includes the spray gun channel 312. The outlet of the spray gun channel 312 faces the lower end of the first support seat body 11, and the connecting pipe is a hose, one end of which is connected to the outlet of the spray gun channel 312, and the other end extends out of the lower end of the first support seat body 11 and is connected to the spray gun.

[0043] In this embodiment, the switching valve seat 23 includes a first connection port 231 facing the first switching valve seat 31, the first connection port 231 includes a first outer port 232 and a first inner port 233, the first end of the first water pipe 5 is inserted into the first outer port 232, and the first end of the spray gun water pipe 7 is inserted into the first inner port 233.

[0045] In this embodiment, the switching valve assembly 2 further includes a transfer seat 24. The switching valve seat 23 is installed in the third valve cavity 133 of the transverse body, and the inlet of the internal channel 234 extends along the height direction. The transfer seat 24 includes an outlet end 241, and the transfer seat 24 is inserted into the switching valve seat 23 from top to bottom, and the water outlet end is inserted into the inlet of the internal channel 234. A first sealing gasket 242 is also sealed between the water outlet end and the inner wall of the internal channel 234.

[0046] In this embodiment, the switching valve group 2 further includes a switching valve core 25. A second sealing gasket 243 is also sealed between the outer wall of the adapter seat 24 and the inner wall of the switching valve seat 23. A water flow space 26 is formed between the first sealing gasket 242, the second sealing gasket 243, the outer wall of the adapter seat 24 and the inner wall of the switching valve seat 23. The water flow space 26 is connected to the first water flow pipe 5 and the second water flow pipe 6 respectively. The switching valve core 25 is arranged in the adapter seat 24. The switching valve core 25 includes a movable valve cavity 251. The movable valve cavity 251 includes an upper outlet 2511, a lower outlet 2512 and an intermediate inlet 2513. The upper outlet 2511 forms the main water outlet 21. The intermediate inlet 2513 is connected to the water flow space 26. The lower outlet 2512 is connected to the outlet end 241. The switching valve core 25 further includes a plunger 252 and an elastic member 253. The plunger 252 moves in the movable valve chamber 251. An upper blocking pad 2521 is disposed at one end of the plunger 252, and a lower blocking pad 2522 is disposed at the other end. The pressure-bearing area of ​​the lower blocking pad 2522 is greater than the pressure-bearing area of ​​the upper blocking pad 2521. When the elastic member 253 is connected to the plunger 252 to push the lower blocking pad 2522 to block the lower outlet 2512, the upper outlet 2511 is connected to the water flow space 26. When the spray gun is turned on, the water pressure pushes the plunger 252 to move so that the upper blocking pad 2521 blocks the upper outlet 2511, and the water flow space 26 is connected to the lower outlet 2512.

[0047] The faucet further includes a water outlet pipe assembly 8. The water outlet pipe assembly is rotatably disposed at the upper end of the adapter seat 24, and the water outlet pipe assembly 8 is connected to the upper outlet 2511. The water outlet pipe assembly 8 includes a water outlet pipe body 81 and a connecting joint 82. The connecting joint 82 is connected to the starting end of the water outlet pipe, and a third sealing gasket 83 is sealed between the outer wall of the connecting joint 82 and the inner wall of the adapter seat 24.

[0048] When in use, the user can open the first switch valve group 3 and / or the second switch valve group 4, and cold water and hot water enter the water flow space 26 through the first water flow pipe 5 and the second water flow pipe 6 respectively. Hot water and cold water can be mixed in the water flow space 26 to form mixed water. The mixed water enters the movable valve chamber 251 from the middle inlet 2513. At this time, due to the action of the elastic member 253 (i.e., the spring), the plunger 252 blocks the lower outlet 2512, and because the spray gun is in a closed state, the mixed water flows out from the upper outlet 2511 into the water outlet pipe body 81, and flows out from the end of the water outlet pipe body 81. After the user turns on the spray gun, water begins to flow through the lower outlet 2512, and the pressure-bearing area of ​​the lower blocking pad 2522 is larger than that of the upper blocking pad 2521. Therefore, the plunger 252 is subjected to water pressure, which overcomes the elastic force of the elastic member 253 and moves to make the upper blocking pad 2521 block the upper outlet 2511, and the lower blocking pad 2522 unblocks the lower outlet 2512. The mixed water passes through the water pipe 7 of the spray gun, enters the spray gun channel 312, and the connecting pipe, and is then sprayed out of the spray gun.

[0049] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
