An electric hot and cold water thermostatic mixing valve core

Abstract

The invention discloses an electric cold and hot water constant temperature mixing valve core, which includes upper and lower parts, the upper part is a control and driving part, and the lower part is a valve core part, and the two parts are connected and fastened by a coil after being plugged. The spool part includes the spool shell and the bottom cover of the spool; the adjustment parts for adjusting the temperature of cold and hot water are installed in the spool shell; the control and driving part includes the upper cover and the lower shell, the control board, the drive motor, the adapter The circuit board is installed in the lower casing, and the driving motor is connected with the driving gear and is connected with the adjusting part in the spool housing through the driving gear. Two motors drive one adjusting slider to control the size of the cold water inlet and the hot water inlet, so that the sizes of the cold water inlet and the hot water inlet can be adjusted at the same time, with flexible control and faster adjustment speed.

Description

technical field [0001] The invention relates to the technical field of valve cores, in particular to an electric cold and hot water constant temperature mixing valve core. Background technique [0002] With the improvement of people's living conditions, whether it is hotels, guesthouses or ordinary families, there is hot water supply for washing, but because the hot water temperature is too high, people cannot use it directly. Mix in proportion and adjust to warm water with suitable temperature before use. To mix cold water and hot water, a hot and cold water mixing valve must be used, but most of the current hot and cold water mixing valves are adjusted by manually rotating and turning the handle to adjust the cold water inlet and hot water inlet inside the valve core. The size of the water outlet is used to adjust the water outlet temperature and water output. After adjustment, the size of the cold water and hot water inlets remains unchanged. Because the pressure and te...

Problems solved by technology

Because it takes a certain amount of time for the change of outlet water temperature to be completely transmitted to the thermoelastic body, this technology cannot quickly respond to the change of water temperature, the adjustment response is slow, and the adjustment accuracy is low, which still cannot achieve a good user experience

[0004] The size of the spool used in the manual mixing valve and the thermostatic mixing valve is not uniform. If the user wants to upgrade from a manual mixing valve to a thermostatic mixing valve, the entire mixing valve must be replaced, resulting in waste
