Abstract

The utility model relates to an electronic constant-temperature tap with a liquid crystal screen, mainly comprising a tap water nozzle, a water outlet flexible pipe, a control box and a liquid crystal display panel. The control box is fixed with a wall through screws, and a mixed water outlet is arranged on the control box comprising a cold water inlet, a hot water inlet, a cold and hot water valve body, a valve core, a temperature sensor, a speed reducing device, a feedback sensor, a control circuit board and a rechargeable battery. After a button of a power supply switch is started, the rechargeable battery starts to supply power, a system starts to work, the inner part of the tap generates water pressure due to water flows in the tap to push a hydroelectric generator to work, the power supply of the rechargeable battery is automatically switched after the hydroelectric generator works, and then the hydroelectric generator directly supplies the power; by operating the liquid crystal display panel, the speed reducing device is controlled through the control circuit body for adjusting the valve core, thereby realizing the adjustment of a water outlet switch and water temperature; and the temperature sensor senses the water temperature and feeds the water temperature back to the feedback sensor, and then the feedback sensor adjusts the water temperature of the valve core through the speed reducing device so that the water temperature is consistent with the water temperature on the liquid crystal display panel.

Embodiment

As Fig. 1, Fig. 2, Fig. 3 and Fig. 4, band liquid crystal screen electronic constant-temperature water faucet, mainly form by water tap water nozzle 1, delivery hose 2, control box 3 and TFT LCD 4, control box 3 is by screw and wall mounted, control box 3 is provided with and blends the mouth of a river, the described mouth of a river that blends is to be connected with an end of delivery hose 2, and the other end of delivery hose 2 is connected with water tap water nozzle 1; Control box 3 comprises cold water inlet 31, water inlet of hot water 32, hot and cold water valve body 38, spool 39, hydroelectric generator 35, temp-sensitive apparatus 33, speed reducer 36, feedback transducer 37, control circuit board 34 and chargeable cell 30; Both are connected to the cold water inlet 31 of control box 3 inside and water inlet of hot water 32 on the hot and cold water valve body 38 by flexible pipe; Temp-sensitive apparatus 33 is embedded in the control box 3 and near blending in the pouring spout and with the described water that blends in the water pipe and contacts; Temp-sensitive apparatus 33 is by reaching and be connected with the organic of TFT LCD 4 by electric wire 5 with control circuit board 34, spool 39, the temperature that makes process blend the water of water pipe outflow passes on the TFT LCD 4 by electric wire 5 and demonstrates Temperature numerical, feedback transducer 37 links to each other with speed reducer 36, speed reducer 36 also links to each other with spool 39 and hydroelectric generator 35, and speed reducer 36 is fixed on the inside of control box 3 by screw; Control circuit board 34 is installed on the bottom in the control box 3, and chargeable cell 30 is installed on the front position in the control box 3; TFT LCD 4 is provided with power switch button 42, raises temperature button 43, downward modulation temperature button 41 and temperature digital display screen 44, and the bottom of TFT LCD 4 also is provided with control circuit assembly 45;

When pressing power switch button 42, chargeable cell 30 begins power supply, system just starts working, water tap is inner because there are current just to produce hydraulic pressure, and then promotes hydroelectric generator 35 work, and chargeable cell 30 power supplys just automatically switch after hydroelectric generator 35 work, directly power by hydroelectric generator 35, by the work that mutually combines of hydroelectric generator 35 and chargeable cell 30, increased the working life of chargeable cell 30 greatly, energy-conservation and environmental protection;

Power switch button 42 just shows a Temperature numerical after starting on the temperature digital display screen 44 on the TFT LCD 4, described this Temperature numerical is the last desired temperature that closes before the water, for example last time shutoff temperature greater than 38 ℃ then system default be 38 ℃; Raise temperature if desired, then press and raise temperature button 43, after this moment, the temperature of fresh target setting was received by system, just this information is delivered to control circuit board 34 by electric wire 5, adjust the adjusting that spool 39 is realized water temperature by speed reducer 36 after the control circuit board 34 reception information simultaneously, and sense the water temperature of being transferred by temp-sensitive apparatus 33, if the water temperature that senses not is the target temperature numerical value that shows on the temperature digital display screen 44, then with this feedback information to feedback transducer 37, feedback transducer 37 is readjusted temperature that spool 39 makes water outlet by speed reducer 36 and is reached goal-setting temperature on the temperature digital display screen 44; In like manner if the downward modulation temperature is then pressed downward modulation temperature button 41, its working principle also is the same;

After pressing power switch button 42 and closing, system is delivered to control circuit board 34 with this information by electric wire 5, combine by hydroelectric generator 35 and feedback transducer 37 by control circuit board 34 program settings spool 39 is transferred to the neutral position automatically, scalded by hot water when effectively preventing next water;

If the user opens the utility model water tap after 15 minutes continuously, then this system is provided with by program and closes water tap automatically, thereby has prevented from effectively to forget that Guan Shui causes the waste of unnecessary water resources;

When if the user does not use the utility model water tap for a long time, and when 30 voltages of the chargeable cell in the control box 3 are lower than 4V, then by solenoid closure on the program setting control circuit board 34, system automatically locks does not work and send prompting: taking out battery charge can then use.
