Abstract
The utility model relates to a water temperature digital display washbasin which comprises a basin body, an LCD displayer arranged on the upper end in the basin body, a battery arranged in the basin body, a microcontroller arranged in the basin body and a temperature measuring circuit arranged on the inner surface of the bottom of the basin body. The LCD displayer is connected with the microcontroller and displays Celsius or Fahrenheit temperature in a digital form. The battery can provide a power supply, and is opened through a battery cover to be replaced. The temperature measuring circuit is connected with the microcontroller, comprises a thermal resistor and an amplification and filtering circuit, and can sense the water temperature in the basin body. The water temperature digital display washbasin can directly display water temperature in the washbasin in real time, is convenient and practical, has high safety, and is particularly applicable to children.
Description
Technical field
The utility model relates to a kind of washbowl of water temperature digital display.
Background technology
Washbowl is generally all thicker, can not estimate the water temperature situation that it is inner from outer surface, so washbowl causes scald easily at all.For the adult, can be before water earlier with the hand water temperature of having a try, just can use under the suitable prerequisite of water temperature to be confirmed; But for children, the experience of life is not abundant or disposition is too urgent, and children cause scald easily.If it is can directly read water temperature numerical value, just much safe from outer surface.
Summary of the invention
The utility model purpose is in order to overcome the problems referred to above that existing washbowl exists, a kind of washbowl of water temperature digital display to be provided, can showing the water in the cup temperature intuitively in real time, and is convenient and practical, safe, is specially adapted to children.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of washbowl of water temperature digital display comprises basin body, is installed in the LCD display of described basin body inner upper end, is installed in the battery of described basin body inside, is installed in the micro controller of described basin body inside, is installed in the temperature measurement circuit of the bottom interior surface of described basin body.
Described LCD display is connected with described micro controller, with the form demonstration Celsius temperature or the Fahrenheit temperature of numeral.
Described battery can provide power supply, opens by battery cover, changes.
Described temperature measurement circuit is connected with described micro controller, is made up of thermistor and amplification filtering circuit, can respond to the water temperature in the described basin body.
The beneficial effects of the utility model mainly show: can show the washbowl water temperature in real time, and safe ready, and control circuit is simple, and cost is low.
Description of drawings
Fig. 1 is the profile schematic diagram of the washbowl of water temperature digital display;
Fig. 2 is the control principle figure of the washbowl of water temperature digital display;
Fig. 3 is the temperature measurement circuit schematic diagram of the washbowl of water temperature digital display.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-Fig. 3, a kind of washbowl of water temperature digital display comprises basin body 1, be installed in the LCD display 2 of described basin body 1 inner upper end, be installed in the battery 4 of described basin body 1 inside, be installed in the micro controller 3 of described basin body 1 inside, be installed in the temperature measurement circuit 5 of the bottom interior surface of described basin body 1.
Described LCD display 2 is connected with described micro controller 3, is arranged on the upper end of described basin body 1 inside, with the form demonstration Celsius temperature or the Fahrenheit temperature of numeral.Three demonstrations are set, and minimum resolution is 0.1 degree, can show the temperature range of 0 ~ 99.9 degree.
Described battery 4 can provide power supply, is arranged on the bottom of described basin body 1, can open by battery cover, changes.Can adopt the little button cell of volume.
Described temperature measurement circuit 5 is connected with described micro controller 3, is made up of thermistor R1 and amplification filtering circuit, is arranged on the inner surface of described basin body 1 bottom, can respond to the water temperature in the described basin body 1.Adopt circuit structure as shown in Figure 3, thermistor R1 and resistance R 2 with power supply VCC dividing potential drop after, the in-phase end of concatenation operation amplifier 6, resistance R 2 two ends shunt capacitance C4, the inverting input of operational amplifier 6 connects output, form a follower, this follower has the high characteristics of input impedance, can avoid the influence of follow-up amplifying circuit to signal source.The output of operational amplifier 6 connects resistance R 3, the in-phase input end of resistance R 3 other end concatenation operation amplifiers 7, the inverting input of operational amplifier 7 connects resistance R 4, resistance R 5, and resistance R 4 other end ground connection, the other end of resistance R 5 connects the output of described operational amplifier 7.The gain of operational amplifier 7 is G=(1+R5/R4).
The output of operational amplifier 7 connects the AD mouth of micro controller 3.Temperature signal is through after amplifying, and detected by analog-to-digital conversion by micro controller 3, and calculates the temperature of thermistor R1.
The concrete course of work is as follows: at first, micro controller 3 is changed the input voltage that reads temperature measurement circuit 5 by analog digital, and this magnitude of voltage is followed variations in temperature and changed; Then, micro controller 3 calculates water temperature according to thermistor R1 property list; At last, micro controller 3 control LCD displays 2 show concrete water temperature.
According to foregoing description, the utility model has overcome the problem that existing washbowl exists, and can be on the basin body surface real-time intuitively demonstration water in basin temperature is convenient and practical, safe, is specially adapted to children.
