Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, and in particular to a steplessly switchable overhead shower head and sanitary ware having the overhead shower head. Background Art

[0002] For example, Chinese invention patent documents CN105728210B and CN105583094B disclose a water circuit switching mechanism, which adopts a ratchet gear transmission mechanism as the core structure of the water circuit switching. The ratchet gear is driven to rotate by an external driving mechanism, and the ratchet gear drives the ratchet gear to rotate, thereby driving the rotating water diversion plate to rotate. The rotating water diversion plate enables the water inlet chamber of the water diversion seat to selectively connect to the water outlet channel, thereby realizing the switching of different water outlet waterways.

[0003] A ratchet is an intermittent motion mechanism that converts linear reciprocating motion or rotational motion into unidirectional stepping motion. On the one hand, the ratchet transmission relies on the precise meshing of the teeth on the ratchet and the tooth grooves on the pawl. If the meshing clearance is not appropriate, it may cause jamming during switching. On the other hand, the manufacturing and assembly precision of the ratchet and pawl are high. If there are processing errors or improper assembly, it may cause uneven meshing, resulting in unsmooth switching. On the other hand, a spring is usually required to maintain the contact between the pawl and the ratchet. If the spring force is uneven or insufficient, the pawl may not be able to stably mesh with the ratchet teeth, causing instability during switching. Summary of the invention
