This warm digital display feeding bottle of suckling has the nursing bottle body 7 of plastics or glass, and the end that it is characterized in that described nursing bottle body 7 is a sheet metal 6, and a temperature-sensitive base 4 is arranged, and a sheet metal 5 is arranged above it, and the latter is connected with the temperature sensor of temperature device for digit-displaying.Described sheet metal 6 and nursing bottle body 7 are by being threaded or being injection molded into one, sheet metal 6 directly is connected with the sheet metal 5 of temperature-sensitive base 4 or pegs graft by the projection of sheet metal 6 following centers and the groove of sheet metal 5 centers, and this groove matches with the size and the shape of projection.Sterilization is convenient in the nursing bottle body 7 easy dismounting that is threaded with sheet metal 5, and sterilization and flushing for preventing to leak, can be provided with the leakproof rubber washer in the bottom of nursing bottle body 7.Sheet metal 6 conducts heat soon accurately than glass or plastics, is easy to the temperature of suckling in the perception bottle.Temperature-sensitive base 4 central upper portion places are porose 8, and the temperature sensor of temperature device for digit-displaying (IC1) is passed hole 8 and is connected with sheet metal 6.Described temperature device for digit-displaying has a shell 1, and it and temperature-sensitive base 4 connect together.Also temperature-sensitive base 4 can be placed in the shell 1 of temperature device for digit-displaying, both adopt drawing and pulling type to connect, and during use temperature-sensitive base 4 are pulled out.LCD LCDs 2 and on and off switch 3 are arranged on this shell 1, circuit board (not drawing among the figure) is housed in the shell 1.

When using this utility model, after printed substrate debugged, be installed in the cabinet 1, the temperature-sensitive feeding bottle is placed on the temperature-sensitive base 4, power-on switch 3, display screen 2 can show the milk coolant-temperature gage.When temperature is crossed when low the heating of trying every possible means; When temperature is too high (in most cases temperature is too high), the cooling of trying every possible means.In the time can drinking near human body temperature, speaker or buzzer just send prompt tone, remind the user.

Circuit of the present utility model as shown in Figure 4, wherein power supply is by the 9V battery powered, K is connected with on and off switch, IC1 is integrated temperature sensor LM35DZ (also available other temperature sensor), and the anodal VCC of on and off switch K is connected with IC1 with C1 through R1, powers to the IC1 power end behind the filtering voltage regulation, the every degree of the latter's outfan (Celsius) output 10mv, but 0～100 ℃ of continuous measurement, IC1 divides three the tunnel to send temperature signal: the one tunnel connects 31 feet of IC6, makes A/D conversion, digital display; Two-way connects 3 and 5 feet of IC3 respectively through resistance R 14, R13 in addition, can detect to reach drinkable temperature whether.IC2 is accurate integrated regulator TL431 (also available other manostat and little power consumption linear voltage regulator), and after resistance R 2 blood pressure lowerings, IC2 exports the 2.5V reference voltage by positive source VCC, and Fen Silu: the one tunnel is connected to 36 feet of IC6 behind R7, RP4 electric resistance partial pressure; One the tunnel is connected to 2 feet of IC3-1 again through R11 behind R6, RP3, R12 electric resistance partial pressure; One the tunnel is connected to 6 feet of IC3-2 again through R21 behind R5, RP2, R10 electric resistance partial pressure, the one tunnel is connected to 2 feet of IC5 behind R4, RP1, R9 electric resistance partial pressure.IC3 is two integrated transporting discharging amplifier OP296, and it is just exporting power supply that 1 foot connects IC4; Export the power supply ground that 7 feet connect IC4.Reference voltage is compared with the voltage of IC1 output behind electric resistance partial pressure, when milk coolant-temperature gage during near human body temperature (as 36～38 ℃), 1 foot of IC3-1 is exported high potential when temperature is higher than 36 ℃, 7 feet of IC3-2 are at output potential 0V below 38 ℃, and both potential differences provide power supply for voice warning circuit IC4.IC4 becomes voice warning circuit (also can form oscillating circuit or music by other integrated circuit, the language integrated circuit replaces) by two 555 circuit bank, and being connected by it with IC3 provides power supply.IC4a and R16, R17, C6, VD1 form the low-frequency oscillatory network that dutycycle does not wait; It exports the high-frequency oscillating circuits that 3 foot control system IC4b and R18, R19, C8 form, export 3 feet at this and produce discontinuous signal, through and capacitor-coupled, promote speaker or buzzer and send prompt tone, reminds people can be drunk.IC6 is A/D change-over circuit IC7107 (also can be replaced by other A/D change-over circuit), its 2～20,22～25 foot connects LCD LCDs 2, LCD LCDs 2 can be three and half (999.9 ℃ of maximum demonstration), also can be two or two and half (maximum show 99 or 99.9 ℃), the magnitude of voltage digitized that IC1 is transmitted, and demonstration on LCD LCDs 2 (during the power supply of civil power lowering and stabilizing blood pressure, also can use light-emitting nixie tube to show).IC5 is integrated transporting discharging amplifier LM358 (also can be replaced by other integrated transporting discharging amplifier).Positive source VCC is connected to 3 feet of IC5 after resistance R 3, R8 dividing potential drop, compare with 2 feet, and output 1 foot of IC5 is connected to power supply 1 foot of IC6.When cell voltage just often, 1 foot of IC5 output high potential is the IC6 power supply; When cell voltage out-of-date, the 1 foot output voltage OV of IC5, LCD LCDs 2 does not show, the reminding user to replace battery.

Resistance in this circuit adopts metalfilmresistor, and RP2, RP3, RP4 adopt accurate multi-turn wiring adjustable resistor.

Whether IC1 ~ the IC6 in the entire circuit can also be made up of a surface-mounted integrated circuit, under-voltage together with battery, can both show on LCD LCDs 2.
