[0038] The present invention is further described below through specific implementation modes.

[0039] Reference Figures 1 to 6 A water diversion valve includes a water diversion body 10, a control member 20, a movable rod 30, a transmission member 40, etc. The water diversion body 10 is a hollow structure, which is provided with a water inlet cavity 11, and the water inlet cavity 11 is provided with a water inlet hole 12.

[0040] The movable rod 30 is inserted into the water inlet chamber 11 and is provided with a plugging head 31 and a water flow channel 32, and the water flow channel 32 is communicated with the water inlet chamber 11. Specifically, a rod body 34 is provided at one end of the movable rod 30, and a water flow channel 32 is provided at the other end. The rod body 34 is inserted into the water inlet chamber 11, and one end of the rod body 34 passes through the water inlet hole 12 and is provided with a plugging head 31, and the plugging head 31 is used to open or close the water inlet hole 12. The water flow channel 32 is provided with a water inlet 37, and the water inlet 37 is communicated with the water inlet chamber 11. A sealing gasket 38 is sleeved on the plugging head 31 to achieve sealing.

[0041] The operating member 20 is sleeved outside the water diversion body 10 and can be operated to rotate. The transmission member 40 is installed between the operating member 20 and the movable rod 30 to convert the circumferential movement of the operating member 20 into the circumferential and axial movement of the movable rod 30, so that the plugging head 31 closes or opens the water inlet chamber 11.

[0042] Specifically, the control member 20 can be sleeved on the end of the water diversion body 10 away from the plugging head 31, and the control member 20 is provided with a mounting groove 21 inside and a handle 22 outside. The transmission member 40 can be at least one ball, and at least one slide rail 33 is correspondingly provided on the outer periphery of the movable rod 30. The ball is embedded in the mounting groove 21 of the control member 20, and slides with the corresponding slide rail 33 to realize the conversion of circumferential motion into circumferential and axial motion of the movable rod 30.

[0043] In practical applications, a guide hole 13 may be provided at the water diversion body 10 at a position relative to the ball bearing to guide the ball bearing during its movement. Preferably, the present invention may include two ball bearings and two slide rails 33 , which are distributed along the circumference of the movable rod 30 .

[0044] Furthermore, the slide rail 33 is axially extended and is in the form of a straight line, an arc, or a curve. Specifically, the outer periphery of the movable rod 30 is unfolded into a plane, and the line of the slide rail 33 along the length direction is a straight line, an arc, or a combination of one or more curves, preferably a straight line or an arc. In the present invention, the control member 20 can be controlled to switch between two positions, such as the position of closing the water inlet chamber 11 and the position of opening the water inlet chamber 11, and the ball bearing can slide between the two ends of the slide rail 33 accordingly.

[0045] The transmission method of the present invention, in addition to the ball and the slide rail 33, can also adopt other transmission structures that can convert circumferential motion into circumferential and axial motion, or convert circumferential motion into axial motion, such as a turbine or worm, gear and rack, etc.

[0046] Furthermore, a convex strip 35 is provided on the outer periphery of the rod body 34, and a guide groove 14 is correspondingly provided on the inner wall of the water inlet hole 12 of the water inlet cavity 11, and the convex strip 35 is embedded in the guide groove 14 to guide the axial movement of the rod body 34. The structure can also be designed as required to provide a guide groove 14 on the outer periphery of the rod body 34 and a convex strip 35 on the inner wall of the water inlet hole 12.

[0047] Furthermore, a diameter reducing portion 15 is provided in the water inlet cavity 11, and a step portion 36 is provided correspondingly on the movable rod 30. The diameter reducing portion 15 is located at the end of the water inlet hole 12 away from the water inlet, and the step portion 36 is formed at the junction of the rod body 34 and the water flow channel 32. When the movable rod 30 moves axially, the step portion 36 abuts against the diameter reducing portion 15 to achieve position limiting.

[0048] Furthermore, the present invention also includes a connector 41, which is fixed between the control member 20 and the water diversion body 10, and can be detachably connected to the water diversion body 10 by threaded engagement. The connector 41 is connected to the water flow channel 32, and is used for connecting an external pipe, such as a shower pipe 42, and the shower pipe 42 and the connector 41 can be locked by a screw 55.

[0049] In the water diversion valve of the present invention, sealing rings 23 are provided between the outer wall of the water flow channel 32 of the movable rod 30 and the inner wall of the water diversion body 10, and between the water diversion body 10 and the inner wall of the joint 41 to seal and prevent water leakage.

[0050] See also Figures 7 to 9 The present invention also proposes a water diversion faucet, comprising a valve body 50, a control valve 51 and the above-mentioned water diversion valve. The valve body 50 is provided with conventional components such as a water inlet, a first water outlet 53 and a second water outlet 54. The water inlet may be one or two, such as a hot water inlet 52 and a cold water inlet 56. The control valve 51 is installed in the valve body 50, and it may be a common control valve 51 such as a switch valve, a thermostatic valve or a mixing valve, and its water outlet is connected with the first water outlet 53 and the second water outlet 54. The first water outlet 53 and the second water outlet 54 may be on the same axis.

[0051] The water diversion body 10 is installed in the second water outlet 54, and its plugging head 31 is opposite to the first water outlet 53. The plugging head 31 opens or closes the water inlet chamber 11 while closing or opening the first water outlet 53. The water diversion body 10 can be locked in the second water outlet by screws 55, and the outer periphery of the water diversion body 10 and the inner wall of the second water outlet are sealed by a sealing ring.

[0052] The water diversion faucet of the present invention, taking the hot water inlet 52 and the cold water inlet 56 as an example, its working principle is as follows:

[0053] By default, see Fig. 9 , the control valve 51 is in a closed state, no water flows out, the plugging head 31 of the movable rod 30 closes the water inlet chamber 11, the ball is located at one end of the slide rail 33, and no water flows out of the first water outlet 53 and the second water outlet 54.

[0054] See also Fig.10 When the control valve 51 is operated to be opened, the water flows from the hot water inlet 52 and the cold water inlet 56 enter the control valve 51 to be mixed, and the mixed water flows out from the water outlet of the control valve 51. Since the water inlet chamber 11 of the water diversion body 10 is closed, no water flows out of the second water outlet 54, and the mixed water enters the first water outlet 53 and flows out.

[0055] See also Fig.11 When the operating handle 22 rotates to another position, the ball rotates with the operating member 20. During the rotation, the movable rod 30 is driven to rotate and move axially at the same time. The ball slides to the other end of the slide rail 33, and the plugging head 31 opens the water inlet chamber 11 and closes the first water outlet 53. The mixed water flows out from the second water outlet 54 through the water inlet chamber 11, the water flow channel 32 and the joint 41.

[0056] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
