Description

Technical Field

[0001] This utility model relates to a faucet valve seat mounting structure. Background Technology

[0002] Chinese invention patent application number 202011103518.X, entitled "Faucet," discloses a faucet structure. The valve assembly includes a valve seat, a valve core, and a fixing seat. The valve seat is disposed in a mounting groove, and the valve core is disposed within the valve seat. The fixing seat connects to the valve seat and presses against and fixes the valve core. The valve assembly also includes a fixing component configured to position and fix the valve seat in the mounting groove. The valve seat is designed as a sleeve, so the valve core does not need to be directly connected to the faucet housing. However, this faucet structure has fewer pipes, and the valve seat does not need to have too many holes, allowing sufficient space within the faucet housing to install this sleeve-shaped valve seat. However, when the valve seat requires many water connection holes, such as two inlet pipes, two outlet pipes, and a pull-out pipe, resulting in limited space within the faucet housing, the above-mentioned valve seat installation method cannot be implemented.

Figure 2 As shown, the installation structure further comprises a handle 930.

[0052] Specifically, the waterway is as follows:

[0053] When the valve core 910 controls the water outlet of the first outlet 240, the second outlet 250 does not outlet water, at this time, the opening and closing of the water outlet of the suction head 710 can be controlled by the solenoid valve:

[0054] If the electromagnetic valve controls the first flow channel 811 and the overflow channel 813 to be communicated, the cold water enters the valve core 910 from the cold inlet 230 and the cold adapter 270 of the valve seat 200 after passing through the cold inlet pipe 510, the hot water enters the valve core 910 from the hot inlet pipe after passing through the hot inlet 220 and the hot adapter 260 of the valve seat, and then flows out from the first outlet 240 and the first outlet adapter 280 of the valve seat 200 after mixing in the valve core 910, and then flows into the first flow channel 811 of the electromagnetic valve shell 810 through one of the outlet pipes 530, and then flows through the flow channel 813 and the suction pipe 700, and finally flows out from the suction head 710; if the electromagnetic valve controls the first flow channel 811 and the overflow channel 713 to be disconnected, the faucet does not flow out.

[0055] When the valve core 910 controls the second outlet 250 to flow out, the first outlet 240 does not flow out, at this time, the electromagnetic valve does not work: the cold water and the hot water flow out from the second outlet 250 and the second outlet adapter 290 of the valve seat 200 after mixing in the valve core 910, and then flow into the second flow channel 812 of the electromagnetic valve shell through the other outlet pipe 540, and then directly flow into the overflow channel 813 and the suction pipe 700, and finally flow out from the suction head 710.

[0056] By limiting the cooperation of the limiting part 130 and the limiting cooperation part 210, the valve seat 200 can be limited forward and backward to avoid moving from the installation cavity 110 into the assembly cavity 120; then, the water pipe is clamped and fixed by the card piece 300, and then the card piece 300 is supported by the support pipe piece 400, and finally the support pipe piece 400 is locked and fixed by the nut assembly. This kind of valve seat installation structure can better support the valve seat 200 which needs to set more waterway adapter holes, and avoid reducing the service life of the valve seat 200 due to insufficient strength of the valve seat 200.

[0057] The above is only a preferred embodiment of the present application, and therefore cannot limit the scope of the present application, that is, equivalent changes and modifications made according to the scope of the present application and the content of the specification should still be within the scope of the present application.
