The early cold and hot water mixing faucet is a two-handle mixer. The user needs to turn the knob to control the cold water and hot water to adjust the amount of cold and hot water, so as to mix into the warm water of the required temperature; the second generation of cold and hot water mixing faucet is a Single lever mixer, its core is a ceramic temperature regulating valve core, the user can adjust the temperature of the mixed water by swinging the handle left and right, and the amount of water output can be adjusted by swinging the handle up and down. However, when the water pressure of hot or cold water changes suddenly, or when the temperature of hot water changes suddenly, the above two mixing faucets must be manually operated to re-adjust the water temperature. The thermostatic faucet can automatically balance the water pressure of cold water and hot water in a very short period of time through the thermostatic adjustment valve core that comes with the faucet, so as to keep the water temperature stable, and no manual adjustment is required at all.

    The standard thermostatic faucet has a knob on the left and right, and the knob on the left adjusts the water temperature: if it is turned forward, the water temperature will drop; if it is turned backward, the water temperature will rise, but it will not turn when it reaches 40°C. This is because it is easy to burn the skin when the water temperature exceeds 40°C. If you need hot water with a higher water temperature, you must press and hold the red safety button on the knob before you can continue to screw it back. The knob on the right controls the water outlet method and water volume: when the scale is aligned, it is in a closed state; screw it forward, and the water outlet nozzle below will flow out, and the more you screw it forward, the larger the water volume; if you screw it backward, the shower will flow out, and the further you screw it back, the more water volume will flow.
