Description

Technical Field

[0001] The utility model relates to the technical field of buttons, in particular to a button structure and a shower faucet. Background Art

[0002] At present, the application of faucet button valve core in shower faucet is very extensive. The button valve core improves people's use experience and enables people to have a more comfortable shower experience. The button switch valve core has the function of one-button opening. The button structure on the market is mostly round buttons, and most of them are designed by assembling button covers, bushings, screws and switching valve cores. There are buckles on the bushings, and the button covers have grooves that match the buckles. The button covers are connected with the bushings, and the bushings are connected with the valve core by screws, so as to realize the connection between the button cover and the switching valve core. However, this design is only suitable for the mechanical switching of the button switching valve core. The button cover is locked to the valve core by screws, and the position cannot be moved and adjusted. This structure has high requirements for the dimensional accuracy of the button body position. Moreover, this structure is not suitable for the large square button structure of the electronic micro switch, and it cannot be waterproof. For example, when it is applied to the electronic micro switch, when the customer uses a shower to sprinkle on it, water is easy to enter the inside, thereby causing damage to the electronic components.
