Description

Technical Field

[0001] The invention relates to a valve, in particular to a universal rocker switching valve. Background Art

[0002] In the prior art, large overhead shower heads are generally single-function. Conventional switching functions are achieved by rotating the panel. However, for overhead shower heads, due to their fixing method (fixed at a high place) and shape (too large), if the conventional switching method is also used, function switching cannot be achieved. Therefore, it is necessary to develop a function switching method suitable for overhead shower heads. Summary of the invention

[0003] The technical problem to be solved by the present invention is aimed at the above-mentioned deficiencies of the prior art. A universal rocker switching valve is provided, which can realize the switching of waterway functions by shaking the rocker in any direction.

A ratchet C is arranged on the inner wall of the movable hole. An actuating cavity is also arranged below the movable hole. The actuating cavity is cylindrical and has a constriction at the lower end. The upper plane of the constriction is a supporting surface.

[0006] A switch plate, movably arranged on the water distribution plate and coaxial with the movable hole, controls the on-off of the water inlet channel, and a ratchet A cooperating with the ratchet C is arranged at the lower middle part of the switch plate;

[0009] The ratchet A, ratchet B and ratchet C interact with each other to form an intermittent rotation switching mechanism, i.e., a ballpoint pen switching mechanism;

[0010] A rocker is movably arranged in the actuating cavity, a push plate is arranged at the upper end of the rocker, and a handle is arranged at the lower end, the handle extends downward from the neck, the upper plane of the push plate and the lower end surface of the actuating member are pressed against each other, and the lower plane of the push plate and the supporting surface are pressed against each other.

[0011] When the rocker swings, one side of the lower bottom surface of the push plate is supported on the support surface, and the upper plane pushes the actuator to move upward, thereby triggering the intermittent switching mechanism to operate and realize the waterway switching function. Therefore, the operation is very convenient, and the rocker has a long handle and a large torque, which has the effect of amplifying the force, and is very labor-saving when operating.

[0012] Optionally, a disc is further provided at the lower end of the actuator, and the disc is in abutment with the push disc. Through the provision of the disc and the structural cooperation between the disc and the push disc, the rocker only needs to swing a small angle to increase the vertical movement distance of the actuator, so that the manipulation feel is better.

Of course, the hole can also be provided on the disc, and the shaft can be provided on the actuator; or the two can be fixed by screws; or the two can be fixed by welding; or the two can be fixed by threads.

[0015] Optionally, the body is provided with a positioning rod, the rotation center of the switching disk is provided with a through hole, the through hole is slidably matched with the positioning rod, and the first reset member is sleeved on the positioning rod, with the upper end against the body and the lower end against the switching disk. By providing the positioning rod, the entire mechanism can run more smoothly and stably, and the life of the product can be improved.

[0016] Optionally, a sealing member is provided between the actuating member and the movable hole.

[0017] Optionally, a sealing groove is provided at the lower end of the movable hole, the sealing member is fixed in the sealing groove, and a fixing member is provided at the lower end to fix the sealing member, the fixing member is annular, and the actuator is slidably sealed with the sealing member and extends downward from the middle of the fixing member.

[0018] Optionally, the handle is in a water drop shape, and can also be designed into other shapes for better aesthetics.

[0019] Optionally, the diameter of the pushing disk is smaller than the inner diameter of the actuating cavity.

[0020] Optionally, a second reset member is further included, and the second reset member is pre-tightened on the disc, so that the disc presses downward against the push disc, and then the lower plane of the push disc is closely attached to the supporting surface of the necking.
