[0038] Example:

[0039] The faucet handle 14 is raised, the third sector groove 7 of the rotating part 11 is attached to the back of the fixed part 12, and the third sector groove 7 covers the third through hole 3, the first arc groove 5, and the second arc groove 6 when the circumference of the rotating part 11 is tangent to the left circumference of the horizontal axis 10 of the fixed part 12 as the "initial position" for explanation:

[0040] Figure 6 As shown, the faucet handle 14 is in the "pull-up position". The circumference of the rotating part 11 is tangent to the circumference on the left side of the horizontal axis 10 of the fixed part 12, and the third fan-shaped groove 7 covers the third through hole 3, the first arc-shaped groove 5, and the second arc-shaped groove 6. The water from the tap is connected to the first through hole 1 of the valve core through the first water inlet 15 of the faucet, and the first through hole 1 is connected to the first arc-shaped groove 5; the hot water from the water heater is connected to the second through hole 2 of the valve core through the second water inlet 16 of the faucet, and the second through hole 2 is connected to the second arc-shaped groove 6, and is gathered and redirected into the third through hole 3 through the third fan-shaped groove 7, and the third through hole 3 is connected to the first water outlet 17 of the faucet. The mixed cold and hot water flows out from the first water outlet 17. At this time, the fourth arc-shaped groove 8 covers the first through hole 1.

[0041] Figure 7As shown, the rotating handle 14 drives the rotating member 11 to turn right 45 degrees through the swing arm 13, and the third sector groove 7 covers the third through hole 3 and the second arc groove 6. The hot water of the water heater is connected to the second through hole 2 of the valve core through the second water inlet 16 of the faucet, and the second through hole 2 is connected to the second arc groove 6, and is collected and redirected into the third through hole 3 through the third sector groove 7, and the third through hole 3 is connected to the first water outlet 17 of the faucet. Hot water flows out from the first water outlet 17. At this time, the fourth arc groove 8 covers the first arc groove 5.

[0042] Figure 8 As shown, the rotating handle 14 drives the rotating member 11 to turn left 45 degrees through the swing arm 13, and the third sector groove 7 covers the third through hole 3 and the first arc groove 5. The water from the tap is connected to the first through hole 1 of the valve core through the first water inlet 15 of the faucet, the first through hole 1 is connected to the first arc groove 5, and is collected and redirected into the third through hole 3 through the third sector groove 7, and the third through hole 3 is connected to the first water outlet 17 of the faucet. Cold water flows out from the first water outlet 17. At this time, the fourth arc groove 8 covers the first through hole 1.
