The implementation principle of a bathroom three-way valve of the embodiment of the application is as follows: when personnel need to supply water by using one or two water outlet channels 12 of the three-way valve, the personnel can twist the twisting part from the outside, thereby rotating the valve core 2, enabling the valve core 2 to feed threads, enabling the end part of the valve core 2 to be close to or far away from the communicating hole 14, and enabling the communicating hole 14 to be closed or opened, enabling the water inlet channel 11 to be communicated with the water outlet channel 12, and enabling water flow to enter the water outlet channel 12, because the two water outlet channels 12 of the three-way valve are mutually independent in opening and closing, the personnel can simultaneously open or close the two water outlet channels 12, and also can independently use one water outlet channel 12, and the three-way valve is suitable for bathroom scenes.

Example 2:

the difference between the present embodiment and embodiment 1 is that, referring to fig. 3 and fig. 4, a sealing element 31 for sealing the water outlet channel 12 is slidably connected to the inner wall of the water storage cavity 3, the sealing element 31 is arc-shaped, the sliding direction of the sealing element 31 is along the circumferential direction of the water storage cavity 3, one side plate surface of the sealing element 31 is attached to the cavity wall of the water storage cavity 3, and the sealing element 31 can slide to the water outlet channel 12 to seal the port of the water outlet channel 12. An abutting piece 32 is fixedly connected to the end portion of the closing piece 31 close to the connecting piece 15, the abutting piece 32 is long, the abutting piece 32 faces the connecting piece 15 along the radial direction of the water storage cavity 3, the surface of the closing piece 31 is coated with a sealing layer, the sealing layer is made of elastic materials, the sealing layer is made of PVC in the embodiment, and the closing piece 31 can also be made of rubber in other embodiments.

The connecting piece 15 is provided with a ring groove 33, the ring groove 33 is coaxial with the threaded hole 16, the ring groove 33 is close to the lower end of the connecting piece 15, the end part of the abutting piece 32 is fixedly connected with a ring sleeve 38, the ring sleeve 38 is rotatably sleeved on the groove wall of the ring groove 33, the ring sleeve 38 is coaxial with the ring groove 33, and the rotating direction of the ring sleeve 38 is around the axial direction of the ring groove 33.

The side groove wall of the ring groove 33 is provided with an arc groove 35, the arc center of the arc groove 35 is positioned on the axis of the ring groove 33, and the arc groove 35 penetrates through the bottom wall of the connecting piece 15 along the length direction of the valve core 2. A stop lever 34 is fixed on the surface of the valve core 2 facing the orifice of the threaded hole 16. The axis of the resisting rod 34 is parallel to the axis of the valve core 2, and the end of the resisting rod 34 faces the bottom wall of the connecting piece 15. The arc groove 35 is internally provided with a penetrating block 36 in a sliding manner, the sliding direction of the penetrating block 36 is along the length direction of the arc groove 35, one end of the penetrating block 36 protrudes out of the bottom wall of the connecting piece 15 to be abutted against the abutting rod 34, and the other end of the penetrating block is positioned on the groove wall of the protruding ring groove 33 and fixedly connected with the side wall of the abutting piece 32.

The groove wall of the ring groove 33 is sleeved with a reset torsion spring 37, the reset torsion spring 37 is coaxial with the ring groove 33, two ends of the reset torsion spring 37 are respectively fixedly connected with the abutting parts 32 and the groove wall of the ring groove 33, so that the closing parts 31 and the abutting parts 32 can be reset, and the elasticity of the reset torsion spring 37 cannot overcome the thread friction force of the valve core 2.
