Description

Technical Field

[0001] The utility model relates to a water channel switching structure which can be automatically reset. Background Art

[0002] Many products on the market currently have no automatic reset function in their water channel switching structures. After the water channel switching is completed, the water channel cannot automatically reset to the default initial state when not in use. This sometimes not only reduces the user experience, but in serious cases it can cause unnecessary safety hazards to users. For example, the spray gun water at the front end of the shower head cannot automatically reset to the standard water or horizontal water function spray state when the user uses up the spray gun water and closes the main valve. When the shower head is plugged into the socket, the next time you use it, as soon as you turn on the main valve switch, the spray gun water toward the ceiling will be turned on immediately, which will wet the ceiling or spray the electrical appliances on the ceiling and cause safety hazards.
