The top of the cavity is movably sleeved, the top of the outer surface of the rotating sleeve 21 is provided with a sealing protective wall 22, and the bottom end of the sealing protective wall 22 extends to the inside of the sealing groove 12, and the left and right sides of the rotating sleeve 21 are respectively provided with connections. The slot hole I23 and the connection slot hole II24, and the connection slot hole I23 and the connection slot hole II24 respectively have a single set of communication position angles with the two groups of through-flow slot holes 13 on the fixed sleeve 11 .

Among them, the segmented structure arrangement between the water valve mechanism and the faucet enables the damaged water valve mechanism or the faucet to be replaced respectively during long-term use. Compared with the existing rotary faucet integrated structure The design can only be replaced as a whole, the manufacturing and maintenance costs are lower, and the scope of application is wider.

In this technical solution, the outside of the fixing sleeve 11 is set as two sets of upper and lower boss-type structures, and the bottom of its outer surface is provided with external threads.

Among them, the setting of the external structure of the fixed sleeve 11 is convenient for the tap water and natural hot water pipes to be threadedly connected at the bottom thereof, and at the same time, the appearance of the various structures on it is more beautiful, and there will be no uncoordinated bulges. .

In this technical solution, the sealing groove 12 will fix the upper part of the sleeve 11 into two annular structures, inner and outer, and the top end of the inner annular structure is lower than the outer annular structure, and the inner width of the sealing groove 12 is larger than that of the sealing protective wall 22 The thickness of the bottom, and the inside of the sealing groove 12 is filled with a third of the height of non-toxic colloidal liquid.

Among them, for the setting of the sealing groove 12, and in cooperation with the fixed pressure plate 3, an effective water sealing mechanism can be formed between the fixed sleeve 1 and the rotating sleeve 2, so that the rotary faucet can be used in the long-term rotation. There will be no water leakage, high stability and reliability, and long service life.

In this technical solution, the outside of the connecting slot I23 and the connecting slot II24 are both waist-shaped holes, and the centerline of the connecting slot I23 and the connecting slot II24 forms an included angle of 60°.

Among them, for the setting of the center line angle between the connecting slot I23 and the connecting slot II24, the two sets of through-flow slot holes 13 on the fixed sleeve 11 are matched. When the water valve mechanism rotates to a certain angle, the sleeve rotates. The tube 21 will automatically block a group of through-flow slots 13 on the fixed sleeve 11, and after continuing to rotate, the other set of through-flow slots 13 on the fixed sleeve 11 will be connected to the connection slot I23 or the connection slot. II and 24 are connected, and when the rotary faucet is rotated between two sinks, it can automatically cut off and block the flow within a certain angle range, so as to prevent the impact of the water flow on the wall of the sink. The phenomenon of splashing water.

In this technical solution, the bottom of the inner cavity of the rotating sleeve 21 is provided with a hemispherical structure, and the top of its outer surface is provided with an external thread.

The use method and working principle of this embodiment:

First of all, according to the general installation and connection method of the faucet, use the external thread on the rotating sleeve 21 and the fixed sleeve 11 to install the shut-off water valve mechanism between the faucet and the control water valve, and connect the slot I23 and the connecting slot at the same time. The central axis between Ⅱ24 is consistent with the groove wall between the two sinks, and then the tap water pipe and the hot water pipe are connected. When you need to put water in the left sink, you can directly rotate the faucet without closing the control. The water valve drives the rotating sleeve 21 to rotate when it rotates the faucet, so that the through-flow slot holes 13 and the connecting slot holes II 24 on the right side that communicate with each other are staggered from each other. It is not connected with the connecting slot I23, so that the water flow groove of the faucet is temporarily blocked, so that when it passes through the wall of the water tank, water will not flow out and cause water splashing. Continue to rotate the faucet to drive When the rotating sleeve 21 rotates until it moves to the middle of the left water tank, the left through-flow slot 13 and the connecting slot I23 communicate with each other, and the water flow from the tap water pipe and the hot water pipe passes through the left connecting pipe. The groove 14 is released from the faucet, and the channel between the flow groove hole 13 on the right side and the connecting groove hole II 24 continues to be blocked; when it is necessary to discharge water in the The passage between the through-flow slot 13 and the connection slot I23 is gradually blocked, and after rotating to a certain angle, the passage between the right through-flow slot 13 and the connection slot II24 is gradually opened. , causing the water flow to be released through it, and at the same time the channel between the left through-flow slot 13 and the connecting slot I23 is blocked, thereby realizing the back and forth rotation between the two sinks. When using the faucet, it no longer needs to be closed. Control the water valve, or the phenomenon of water splashing caused by the impact of the water flow on the wall of the water tank, it is convenient and reliable to use and has high stability.
