Description

Technical Field

[0001] The utility model relates to a valve core structure. Background Art

[0002] In the existing temperature control and function switching composite valve core, especially in the American shower system, the temperature control handle and the function handle are integrated. The handle is closed when it is in the middle. When it is rotated to one side, one function is turned on and the temperature is adjusted (from cold to hot). When it is rotated to the other side, the other function is turned on and the temperature is also adjusted (from cold to hot). When consumers switch from one function to another, they need to transition from the current usage temperature to cold water, then turn off the water flow, and then adjust from cold water to the appropriate temperature for consumers. This causes the handle to have a large angle when switching and a long switching time. This not only wastes the water resources flowing out when switching functions, but also requires the temperature to be readjusted to reach the water temperature before switching functions. Moreover, the switching is undamped, causing consumers to be unable to control their strength and easily turn the handle, resulting in excessively high water outlet temperature, inability to perform precise control, and a poor overall experience.
