How an easy-to-use faucet works:

Cold water enters the cold water supply channel 210, the first cold water inlet channel 321, and the second cold water inlet channel 324 from the cold water pipe 211, and the hot water enters the hot water supply channel 220, the first hot water inlet channel 322, Inside the hot water inlet channel 2 325, that is, the cold water supply channel 210 supplies water to the cold inlet water channel 1 321 and the cold inlet water channel 2 324 at the same time, and the hot water supply channel 220 simultaneously serves as the hot water inlet channel 1 322 and the hot water inlet channel 2 325 for water supply; when the faucet is fully closed, the spool 300 is also fully closed.

The user turns the handle 622, so that the handle 622 drives the valve stem 620 and the switching movable tile 610 to rotate synchronously. After the switching movable tile 610 rotates until the cold water hole 611 communicates with the cold inlet water channel 1 321, the water outlet hole 613 is connected to the outlet water channel. One 323 is connected, and the cold water in the cold water inlet channel one 321 is discharged through the water mixing chamber 642, the water outlet hole 613, the water outlet channel one 323, the common flow channel 230, the water supply channel 410, and the outlet one 420; After the hot water hole 612 is connected with the hot water inlet channel 1 321, the water outlet hole 613 is connected with the water outlet channel 1 323, and the cold water and hot water enter the mixing chamber 642 to mix into warm water and then Discharge through the water outlet hole 613, the water outlet channel one 323, the common flow channel 230, the water supply channel 410, and the water outlet one 420; only after the hot water hole 612 is connected with the hot water inlet channel one 322, the water outlet hole 613 and the water outlet channel one 323 connected, the hot water is discharged through the water mixing chamber 642, the water outlet hole 613, the water outlet channel 1 323, the common flow channel 230, the water supply channel 410, and the drain outlet 420, so as to realize normal water (cold water, hot water, warm water) Water outlet; after switching the moving tile 610 to cover the cold water inlet flow channel one 321, the hot water inlet flow channel one 322, and the water outlet flow channel one 323, the valve core 300 is in the closed state, and the water outlet tap 400 is closed.

The user presses the button 7223, so that the button 7223, the pressing tube 722 and the push rod 723 slide in the direction of the rotating seat 724 as a whole. Since the guide surface 2 7222 on the claw 7221 is in contact with the guide surface 3 7232 on the indexing claw 7231, pressing After the pipe 722 and the push rod 723 slide towards the direction of the rotating seat 724, the guide surface 4 7233 on the indexing claw 7231 is pressed against the guide surface 5 7242 on the rotating claw 7241, because the indexing claw 7231 is still located in the guide groove 7212 at this time. Inside, the indexing claw 7231 that slides along the direction of the rotating claw 7241 pushes the rotating claw 7241 and the rotating seat 724 to rotate synchronously. One rotation of the seat 724 is completed to realize the opening or closing of the switch movable tile 710; after the external force is removed, the return spring 725 pushes the push rod 723 and the pressing tube 722 to reset as a whole, that is, the pushing rod 723 and the pressing tube 722 are far away from the rotating seat 724 Because the return spring 725 exerts a force on the push rod 723 away from the direction of the rotating seat 724, and the indexing claw 7231 loses the limit of the guide groove 7212, the guide surface 3 7232 on the indexing claw 7231 slides along the guide surface 2 7222 Move to the first guide surface 7213, and then the indexing claw 7231 slides into the adjacent guide groove 7212 along the first guide surface 7213, so that the push rod 723 rotates once, and the indexing claw 7231 is located above the highest point of the fifth guide surface 7242 again.

When the switch movable tile 710 is in the open state, the cold water in the cold inlet water channel 2 324 enters the mixing chamber 642 through the escape hole 615 and the gap 711 sequentially, and the hot water in the hot water inlet channel 2 325 sequentially passes through the avoidance hole 615 , gap 711 enters in the water mixing chamber 642, cold water and hot water are mixed into warm water in the water mixing chamber 642 and then pass through the water outlet channel two 326, the connecting channel one 241, the connecting pipe one 2411, the tee joint 820, the connecting pipe Two 2421, connecting flow channel two 242, water supply pipe 411, and drain two 430 are discharged; while connecting pipe one 2411 is passing water, diaphragm pump 830 will clean the liquid (detergent, soap, hand sanitizer) in the cleaning liquid barrel 500 Inhale into the three-way joint 820, so that warm water and cleaning liquid form cleaning liquid mixed water (detergent water, soap liquid water, hand sanitizer water) in the three-way joint 820 and the connecting pipe two 2421, that is, the water is discharged from the second drain port 430 The water is the cleaning fluid mixed with water.

When the switch movable tile 710 is in the closed state, the switch tile 710 completely covers the second cold water inlet flow channel 324 , the second hot water inlet flow channel 325 and the second water outlet flow channel 326 .

The faucet can discharge cold water, hot water, warm water or cleaning solution mixed water (detergent water, soap liquid water, hand sanitizer water) according to the actual needs of users, and has various functions and is convenient for users to use.

The above descriptions are only exemplary implementations of the present utility model, and are not intended to limit the protection scope of the present utility model, which is determined by the appended claims.
