the valve rod 3 is arranged in the water channel 21 in a penetrating way, one end of the valve rod, which is close to the first water outlet 12, is provided with a baffle disc 31, and the baffle disc 31 is used for blocking a port of the water channel 21;

the sealing gasket 4 is arranged on the end part of the valve rod 3 close to the second water outlet 13 and is used for blocking the port of the water channel 21; the projected area of the gasket 4 in the direction of the second water outlet 13 is smaller than the projected area of the baffle disc 31 in the direction of the first water outlet 12.

Specific embodiments of the utility model are shown below.

The port of the water channel 21, which is close to the second water outlet 13, is provided with a first inclined surface 23, the surface of the sealing gasket 4, which faces the first inclined surface 23, is provided with a second inclined surface 41, and the second inclined surface 41 is movably attached to the first inclined surface 23 along with the axial movement of the valve rod 3 in the water channel 21. By designing the first inclined surface 23 to be matched with the second inclined surface 41, the contact area between the sealing gasket 4 and the shaft sleeve 2 can be increased, and the sealing effect can be improved.

The port of the water passing channel 21, which is close to the first water outlet 12, is provided with a flaring 24, the inner diameter of the flaring 24 is larger than the inner diameter of the water passing channel 21, and the inner diameter of the flaring 24 is smaller than the diameter of the baffle disc 31, so that the baffle disc 31 can completely seal the flaring 24. The flaring 24 is designed to make the contact area between the water flow and the baffle disc 31 larger when the water flow flows to the baffle disc 31, so that the baffle disc 31 is easier to be pushed to axially move, and the functional stability of the baffle disc is ensured.

A water passing cavity 14 is arranged in the valve body 1; the water inlet 11 and the second water outlet 13 are respectively communicated to the peripheral surface of the water passing cavity 14, and the first water outlet 12 is communicated to the end surface of the water passing cavity 14; the shaft sleeve 2 is connected to the side wall of the water passing cavity 14 in a sealing way, and a space for the valve rod 3 and the sealing gasket 4 to move axially is reserved between the shaft sleeve and the end part of the water passing cavity 14.

Further, a first sealing ring 5 and a second sealing ring 6 are respectively sleeved at two ends of the shaft sleeve 2; the first sealing ring 5 and the second sealing ring 6 are elastically matched on the inner wall of the water passing cavity 14 and are respectively positioned at two axial ends of the water passing hole 22.

Meanwhile, the inner wall of the water passing cavity 14 is provided with a limit step 15 and a clamping groove 16; the periphery of the shaft sleeve 2 is provided with a limit flange 25 and a claw 26; the limit flange 25 abuts against the limit step 15, and the claw 26 is elastically matched in the clamping groove 16, so that the shaft sleeve 2 is installed in the water passing cavity 14.

Furthermore, a circle of annular groove 27 is concavely formed on the peripheral surface of the shaft sleeve 2, the annular groove 27 is communicated with the water inlet 11 after the shaft sleeve 2 is installed, and the water passing hole 22 is arranged at the bottom of the annular groove 27, so that the water passing hole 22 is communicated with the water inlet. Through designing ring channel 27 for form an annular water course between its global and the lateral wall of water cavity 14 after axle sleeve 2 installs, water fills in annular water course earlier after flowing into from water inlet 11, flows into water hole 22 again, no longer has the restriction (need not aim at water inlet 11) to the convenience when installing of water hole 22 this moment, and the equipment of product is more convenient. In this embodiment, two water passing holes 22 are provided at the bottom of the annular groove 27 to increase the flow rate.

The end of the valve rod 3 is provided with a mounting flange 32, the sealing gasket 4 is sleeved at the end of the valve rod 3 and is abutted against the mounting flange 32, and then the axial limit is realized through a clamping ring 7, so that the installation is completed.

Referring to fig. 2 to 5, the working principle of the present utility model is as follows:

when in assembly, the water inlet 11 is connected with a water supply pipe, the first water outlet 12 is connected with a hand-held shower head (or other types of water outlet devices, mainly provided with a switch valve) with a switch valve, and the second water outlet 13 is connected with a top-spraying shower head (or other types of water outlet devices without requirements on waterway control functions);

referring to fig. 2 and 3, when the switching valve of the hand shower is in an open state, the pressure difference between the first water outlet 12 and the second water outlet 13 and the water passing channel 21 is close, the valve rod 3 and the sealing gasket 4 move downwards (direction in the figure) under the action of water pressure due to the fact that the projection area of the sealing gasket 4 in the direction of the second water outlet 13 is smaller than the projection area of the baffle disc 31 in the direction of the first water outlet 12, so that a port communicated with the first water outlet 12 by the water passing channel 21 is opened, and water flows out from the first water outlet 12;

referring to fig. 4 and 5, when the switching valve of the hand shower is in a closed state, the pressure difference between the first water outlet 12 and the water passing channel 21 is 0, and the pressure difference between the second water outlet and the water passing channel 21 is larger, so that the valve rod 3 and the sealing gasket 4 move upwards (in the direction in the figure), thereby opening the port of the water passing channel 21 communicating with the second water outlet 13, and water flows out from the second water outlet 13.

According to the scheme, the shaft sleeve 2 is arranged in the valve body 1, the shaft sleeve 2 is matched with the valve rod 3 capable of moving according to water pressure and the sealing gasket 4 connected to the end part of the valve rod 3, when the handheld shower is used, the moving states of the valve rod 3 and the sealing gasket 4 can be indirectly controlled through the switching valve of the handheld shower only by connecting the first water outlet 12 to the handheld shower with the switching valve, so that a waterway inside the three-way valve is automatically switched according to the switching water state of the handheld shower when a user uses the handheld shower, additional operation on the three-way valve is not needed, and the handheld shower is more convenient; because the hand-held shower with the switch valve is already the existing mature technology, the hand-held shower is convenient to use in a matched mode, and the three-way valve does not need to be provided with an additional operation switch, so that the hand-held shower is simpler in product structure and lower in cost.

The above examples and drawings are not intended to limit the form or form of the present utility model, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present utility model.
