Description

Technical Field

[0001] The utility model relates to the technical field of shower heads, in particular to a button linkage switching structure of a shower head. Background Art

[0002] In addition to the ordinary water splash function, some shower products have added special functions such as spray gun water and pause water to meet the special needs of users. Among the special functions of the shower head, the spray gun water function has a strong water output and is not used in normal bathing. If the pause water function is set on the button that switches to the ordinary water splash, the user experience will be poor because the process of switching the water splash requires multiple presses. Therefore, these special functions usually need to be set with independent buttons for users to control.

[0003] At present, showers with special functions are all operated in a double-button or knob-controlled mode. Taking button-type control as an example, in existing shower products, one button is used to link the valve stem in the water diversion body, thereby realizing the switch between ordinary water splash and special function, and under the action of the spring, it is ensured that water flows to the water outlet panel under normal conditions. The possible problem is: when the button is pressed and the shower is switched to the special function mode, the valve stem can continue to compress the spring under the action of water pressure and maintain the same position, so that the shower maintains the special function mode. As long as the shower continues to take in water (that is, the switch on the wall is not turned off), the spring cannot reset the valve stem. At this time, if you need to switch to the ordinary water splash mode, you need to turn off the shower switch on the wall first, which is more complicated to operate and has a poor user experience.

[0039] Specific embodiments of the present utility model are shown below.

[0040] In this embodiment, the first water outlet device 3 is a water outlet panel, the second water outlet device 4 is a nozzle capable of spraying gun water, and the first water inlet 12 is located at the rear end of the shower body 1, the water dividing member 2 is installed on the upper surface of the shower body 1, the first water outlet device 3 is installed on the lower surface of the shower body 1, and the second water outlet device 4 is installed at the front end of the shower body 1; at the same time, the second button 30 is movably arranged on the water outlet panel so as to be linked with the switch member 8.
