Rotary temperature-regulating thermostatic valve for pressing switch of faucet

Abstract

The invention discloses a faucet push switch rotary temperature adjusting thermostatic valve which comprises a valve body, a temperature adjusting cavity is formed in the lower end of the valve body, a cold water inlet and a hot water inlet are formed in the side face of the temperature adjusting cavity, a mixed water outlet is formed in the middle of the valve body, and an adjusting seat is installed in the upper end of the valve body and can rotate in the valve body. A switch cavity is formed in the upper end of the adjusting base, a pressing switch device is installed in the switch cavity, a temperature adjusting sliding block is clamped to the lower end of the adjusting base in the circumferential direction, the temperature adjusting sliding block and the valve body are in threaded transmission connection, and when the adjusting base rotates, the temperature adjusting sliding block can be driven to slide in the axial direction, a temperature sensing element is installed in the temperature adjusting sliding block, and an ejector rod is installed at one end of the temperature sensing element. And a temperature sensing area is arranged at the other end of the top rod and is positioned above the top rod. According to the thermostatic valve, cold water and hot water flow in the valve body smoothly, a waterway cannot be bent for multiple times, the temperature sensing element senses the temperature accurately, adjustment is more timely, the temperature fluctuation range is smaller in the using process, and the fluctuation time is shorter.

Description

technical field [0001] The invention relates to the technical field of bathroom faucets, in particular to a faucet press switch rotary thermostat valve. Background technique [0002] The faucet is a device used to adjust the temperature of the water outlet and control the water outlet switch. Existing faucets are generally equipped with at least one thermostat valve and an on-off valve. The thermostat valve is used to control the ratio of cold and hot water to control the temperature of the mixed warm water. The on-off valve core controls the outlet of warm water. Correspondingly, two installation holes need to be opened on the main body of the faucet to install the thermostat valve and the on-off valve respectively. At the same time, the interior of the faucet needs to be provided with a flow channel for the warm water mixed by the thermostat valve to the inlet of the on-off valve and the outlet of the on-off valve to the faucet. The flow channel of the outlet. The intern...

Problems solved by technology

At the same time, the temperature sensing area of ​​the temperature sensing element is close to the cold and hot water inlet. After the cold and hot water enters the valve core, it will contact the temperature sensing area of ​​the temperature sensing element without being fully mixed. The temperature sensing element cannot accurately mix evenly After the water temperature is sensed, resulting in inaccurate temperature adjustment

In addition, two sealing rings need to be set between the piston assembly and the lower casing, one is between the outer peripheral wall and the lower casing, and the other is between the inner peripheral wall and the lower valve body. The two sealing rings cause the piston assembly to slide Large resistance, inflexible sliding, unable to change the mixing ratio of hot and cold water immediately, and the water temperature fluctuates greatly during use

And the sealing ring obtained between the inner peripheral wall and the lower valve body is installed in the sealing ring of the inner wall of the lower valve body, where the space is small, and it is very inconvenient to install the sealing ring
