Description
Technical Field
The invention relates to a water temperature regulating device for nursing and cleaning, in particular to a water temperature regulating device.
Background
At present, china is still an extremely water-deficient developing country, but economic construction and environmental protection conservation are not neglected, and development of both the economic construction and the environmental protection conservation becomes increasingly important. The investigation shows that the nursing and cleaning of inpatients need proper warm water, the water faucet is firstly opened to enable water to flow for a while in nursing, and then the cleaning is performed after the outlet water temperature is proper, when the water temperature is higher or lower, the hot water or the cold water can be enabled to flow for a while after the switch is regulated, and the water resource in the waiting process can be greatly wasted. Firstly, the waste of water resources is unfavorable for economic construction and environmental protection and saving, and secondly, the comfort of nursing and cleaning can be greatly reduced. The domestic research on the intelligent temperature control faucet has greatly progressed, and part of the research has been put into use, thereby providing great convenience for nursing, cleaning and various water. Based on PT100 thermistor, north China electric university has designed control by temperature change tap, and the temperature measurement contact is placed in outlet pipe inside, measures the temperature of waiting to go out water. If the measured temperature is lower than the preset expected temperature, the singlechip receives the signal and then judges that the temperature is cold water, and at the moment, the electromagnetic valve turns on the temperature control switch, and the judged cold water flows back to the water receiver; otherwise, the water heater is judged to be the hot water needed by people, the electromagnetic valve is closed to control the temperature control switch, and the hot water flows out of the water faucet. Meng Tuoke A pipe wall type thermostatic valve is designed by the fluid equipment limited company, a sensor for sensing water temperature is arranged at a water outlet of a thermostatic water mixing valve, a valve core is pushed by sensing the water temperature, a cold water inlet and a hot water inlet are opened or blocked, and the water inlet proportion of the cold water and the hot water is adjusted; when the water outlet temperature is set through the temperature knob, when the water inlet temperature and the water inlet pressure of the cold water and the hot water are changed, the sensor senses the water temperature and drives the valve core to move, and the water inlet proportion of the cold water and the hot water is also changed along with the change, so that the water outlet temperature is kept stable.
The defects of the traditional temperature control device are that: (1) The size of the water inlets at the two ends is changed through the rotation of the valve core, so that the size of the cold and hot water inlets is simply controlled, and the mixing proportion of hot water and cold water is not well controlled; (2) The hot water and the cold water have different water inlet pressures, the pressure of the two water inlets is in a continuous fluctuation state, the mixing proportion of the cold water and the hot water is continuously changed, and the water temperature is easy to be suddenly high and suddenly low; (3) When the water mixing valve is regulated to change the size of a water inlet at one end, the water inlet is unchanged in a short time due to the fact that water pressure is correspondingly increased or reduced due to inertia and viscosity of water, so that the water temperature is not changed, and a period of time is needed to wait after each time of switch regulation.
