Description

Technical Field

[0001] The invention belongs to the technical field of kitchen and bathroom accessories and relates to a rotary water distributor. Background Art

[0002] The existing rotary water distributor generally includes a water distributor body, a valve stem and a water distributor assembly. The water distributor state is switched by driving the water distributor assembly to rotate in the inner cavity of the water distributor body through the valve stem.

[0003] For example, Chinese invention patent application CN110486487A discloses a water divider, which includes a valve body and a valve stem, the valve body having a through hole extending axially therethrough, the lower end of the valve stem being rotatably inserted in the through hole of the valve body, the upper end of the valve stem extending upwardly out of the upper end of the valve body, the lower end face of the valve body having a water outlet 1, the outer peripheral surface of the valve body being respectively provided with a water outlet 2 and a water inlet, the water inlet being located between the water outlet 1 and the water outlet 2, a blocking disc being provided in the through hole of the valve body between the water inlet and the water outlet 1, the outer peripheral surface of the blocking disc being sealingly connected to the inner wall of the through hole and the blocking disc A water hole that runs through the upper and lower parts is provided on the upper part; the lower end of the valve stem is connected to the rotating disk and can drive the rotating disk to rotate; the lower end side of the valve stem has a blocking part that can block or open the second water outlet when rotating; the upper end of the valve stem has a connecting part, the peripheral surface of the connecting part has straight teeth, the outer peripheral surface of the middle part of the valve stem has a plurality of annular grooves, and the annular groove is embedded with a sealing ring; the lower end of the valve stem is tubular or cylindrical and the blocking part is a part of the side wall of the lower end of the valve stem, and the outer peripheral surface of the lower end of the valve stem is provided with a water hole corresponding to the second water outlet. The handle is connected to the connecting part at the upper end of the valve stem, and the outer peripheral surface of the valve stem and the inner wall of the valve body are sealed to prevent leakage. When the valve stem rotates, the blocking part blocks the second water outlet or the water hole is connected to the second water outlet.

[0004] The shortcoming of the above-mentioned water distributor is that the lower end of the valve stem is sealed and connected to the inner wall of the valve body, and the connection itself is relatively tight. When the water pressure is high, the sealing structure will be further deformed and combined more tightly with the inner wall of the valve body, resulting in a heavier feel and even difficulty in turning. After long-term use, components are prone to damage. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a rotary water distributor which has the advantages of flexible rotation, good hand feel and long service life.

[0009] In the above-mentioned rotary water distributor, the middle water hole is a groove-shaped structure that penetrates up and down and is open on the side. A pair of middle water holes are provided and are distributed symmetrically with the center, and the solid part between the middle water holes forms a blocking structure.

[0010] In the above-mentioned rotating water distributor, the upper water holes and the lower water holes are each provided with a pair and are respectively distributed in a centrally symmetrical manner, the upper water holes and the lower water holes are staggered, and the upper water holes, the middle water holes and the lower water holes are all corresponding fan-shaped structures; preferably, the angles of the upper water holes, the middle water holes and the lower water holes are all 90°.

For example, the upper / lower concave-convex structure for circumferential limiting includes: a limiting convex strip arranged axially on the outer wall of the upper / lower ceramic sheet, and a limiting groove arranged axially on the inner wall of the water divider body, the limiting convex strip and the limiting groove cooperate to form a circumferential limiting structure, and the upper / lower concave-convex structure can be arranged in multiple groups and evenly distributed along the circumference.

[0012] In the above-mentioned rotary water distributor, an axial connection plane is arranged on the side of the valve stem connecting end, an avoidance hole for the valve stem connecting end to pass through is arranged on the upper ceramic plate, and an axial hole fixedly connected to the valve stem connecting end is arranged on the middle ceramic plate; further, the axial hole is a blind hole, and after assembly, the axial hole forms a lower limit structure of the valve stem; the upper end of the valve stem is sealed and connected to the upper end of the water distribution body by a plurality of O-rings, a limiting outer convex ring is arranged on the outer wall of the valve stem, a wear-resistant ring is arranged between the limiting outer convex ring and the water distribution body, and after assembly, the limiting outer convex ring forms an upper limit structure of the valve stem.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention provides a rotating water divider, which is composed of an upper ceramic plate, a middle ceramic plate and a lower ceramic plate to form a water divider assembly, and the valve stem drives the middle ceramic plate to rotate relative to the upper ceramic plate and the lower ceramic plate to achieve the function of upper and lower water dividers. The rotating part of the present invention is only the middle ceramic plate, and the upper and lower water flow parts are both fixed parts. Therefore, the structure of the water divider assembly is simpler and the water divider waterway is smoother. The valve stem of the present invention no longer bears the water divider function, and a valve stem with a simpler structure can also be used, and it will no longer be affected by water pressure. The upper and lower surfaces of the middle ceramic plate of the present invention rotate relative to other ceramic plates. Since the friction between the ceramic plates is small during rotation and the sealing is good, the rotation is more flexible, the feel is better, and the service life is longer (the number of rotations can reach 500,000 times, while the existing water divider is only 40,000 to 50,000 times).
