Description

Technical Field

[0001] The invention relates to the technical field of kitchen and bathroom, in particular to a push button switching structure and a push button switching shower head. Background Art

[0002] The push-button switching structure is a widely used switching structure in water outlets with switching functions (especially showers). The main reason is that its push-to-dial switching method is more in line with human mechanics, and the operation is convenient and intuitive. At present, the push-button switching structure on the market is mostly used with a ratchet or rack-driven water-dividing plate structure with a gear. Among them, the ratchet and ratchet structure is relatively complex. At the same time, the coaxiality requirements of the ratchet, ratchet and water-dividing plate are high during installation, and the ratchet is an elastic component. Its elasticity and strength need to be considered at the same time during design. It is necessary to avoid the problem of large elasticity and difficulty in use or even the twisting of the water-dividing plate during reset, and to avoid the problem of small elasticity and brittle material being easily damaged or even switching failure. For the water-dividing plate structure with a gear driven by a rack, there is also a problem of high coaxiality requirements when installing parts, and high requirements for the precision of parts. In addition, the water-dividing plate needs to adopt a pressed rotating structure, which has poor installation stability. When discharging water, the water-dividing plate is prone to overturning due to hydraulic jacking, and its sealing is easily damaged, resulting in dripping problems. Summary of the invention
