DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a temperature indicating device, and more particularly to a temperature indicating device that uses different colors to display different temperatures. [Prior Art] Japanese daily necessities often fail to remind us of the actual degree of hot and cold, such as containers for beverages. We can only guess the hot and cold by hand or by using the test. If it is observed that there is water droplets on the outside of the container that are condensed due to cold, it can be known as a cold drink. If smoke is observed, it may be ice water or hot water, assuming that it is very hot and not noticeable. If you are not careful, you may get burnt. When a busy mother feeds baby milk or takes care of a person who is mentally handicapped, it is often determined by the temperature of the caregiver that the temperature of the food to be cared for is not related to the caregiver's temperature. Nothing is caused by accidents. SUMMARY OF THE INVENTION In view of the above, the concept of the present invention is to use an intuitive vision to replace the temperature number to determine the change in temperature, and let the user to look at the color of the water temperature. Accordingly, it is an object of the present invention to provide a temperature indicating device that displays different temperatures of hot and cold using different colors. Thus, the temperature indicating device of the present invention comprises a temperature sensor, a driving module and an indicating light source, wherein the temperature sensor outputs a temperature detecting signal representing a measured temperature; the driving module is lightly connected to the The temperature sensor, 200844413 is used to detect the temperature difference according to the temperature 夹-clip, degree/, reference temperature, the rain represents a driving signal reaching different predetermined temperatures, and the indicating light source (4). (4) Module ' It is driven by the driving signal and displays different colors after reaching the predetermined temperature. Since the temperature indication of the present invention is set to reach different predetermined temperatures, the indicator light source displays the color of the different temperatures & _ degrees, so that the user can directly observe the color of the indicating light source to distinguish the hot and cold. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the detailed description of the preferred embodiments. Referring to Figures 1 and 2, a preferred embodiment of the temperature indicating device i of the present invention comprises a temperature sensor U, a driving module 1A and an indicating light source 15. The temperature sensor U is used to output a temperature detecting signal 101 representing a measured temperature τ. The temperature sensor 本 of the preferred embodiment is an integrated circuit of the type AD590, and the working principle is The output current varies linearly with temperature depending on the temperature of the sensing. However, other similar temperature sensors can be used, not limited to this. The driving module 10 has a subtracting circuit 12, an amplifying circuit 13 and a comparing circuit 14 for measuring the temperature τ measured by the temperature sensor 11 and the temperature predetermined signal of the predetermined predetermined plurality of predetermined temperatures 内部 Τ Τ For the difference, the output represents a driving signal 1〇2 reaching each predetermined temperature ΤγΤη to illuminate the indicating light source 15 of a different color. Referring to FIG. 2, the subtraction circuit 12 includes an operational amplifier servant and a plurality of electric power 200844413 resistor R two Rh, the operational amplifier u! has two input terminals (_) (+) and one round output terminal, and the negative input terminal (1) of the operational amplifier U! A resistor Rn ' is connected across the output terminal and connected to the temperature sensor 丨丨 in series with a resistor and a parallel resistor Rn and grounded to receive a temperature representative from the temperature sensor u. a voltage Vi ·, the positive input terminal (+) of the operational amplifier is connected in parallel with the variable resistor RU and a resistor Rls, receiving a second voltage V2 representing a reference temperature (for example, the room temperature T0 at that time); Amplifier. The round output outputs a voltage difference Υδτ representing both the first voltage % of the measured temperature T and the first voltage V2 representing the reference temperature %. Therefore, the voltage difference νΔτ or η represents the room temperature 相对 ( The temperature is high or low. Referring to FIG. 2 and FIG. 3, the amplifying circuit 13 is coupled between the subtracting circuit 12 and the comparing circuit 14 for amplifying the voltage difference νΔτ as an output voltage Vi, and outputting it to the comparing circuit 14, because the output voltage Vi is a voltage The difference is a multiple relationship, so it also represents the temperature level relative to the room temperature τ〇 at that time. Referring to FIG. 3, the comparison circuit 14 has a plurality of comparators uu-uln, and each of the comparators uu-uln receives a divided reference signal Vren~Vr and receives the output voltage Vi of the amplifying circuit 13, thereby comparing the output voltages. % and each reference signal Vref1 VVrefn are different, and according to the comparison result, a driving signal representing each of the pre-twisting temperatures T1 to τη is output. For example, the 电路17324 and the HD74LS00 can be used in the comparison circuit 14. The two integrated circuits respectively include four comparators and four NANds. It is also possible to use different sizes of the sigma diodes when passing through the temperature sensor u. The voltage value of the transition is higher than the voltage specification of the sinus diode, and has the same function as the comparison circuit 14. 200844413 The light source u is lightly connected to the comparison circuit 14, and has a plurality of optical elements Di~Dn. Each of the light-emitting elements D has a large amount of light, and is used to drive the driving signal 102 and display different temperatures when the predetermined temperature is reached. Color and its color representation, can use red to represent high temperature, green to represent % and blue to represent low temperature. The decision of the color, " goods, j M first 仃 to the actual temperature after the speculation to determine the range of each color. Reference signal obtained by dividing the complex resistor-Thunder, η8p3, and the voltage source VCC
Vrefn是用來當作是否點亮對應顏色的發光元件^的門檻， 預定溫度τη越高之輸出電M %，與其比較的參考訊號 越问’而代表溫度τη越低之輸出電M Vi，與其比較的參考 訊號vrefn越低，例如：Vrefl=h Vref3=h依此類推。 因此’當比較器un接收到對應的參考訊號Vrefn才會令 對應的發光元彳Dn導通而發出對應顏色的光線，而需要高 电位參考成唬vrefn之發光元件Dn則不會被導通，反之亦然 ;其溫度變化及導通與否之比較可參閱表i :Vrefn is a threshold for determining whether or not to illuminate a corresponding color of the light-emitting element ^, and the output voltage M% having a higher predetermined temperature τη, the more the reference signal is compared with the lower the temperature τη, the output power M Vi The lower the reference signal vrefn is compared, for example: Vrefl=h Vref3=h and so on. Therefore, when the comparator un receives the corresponding reference signal Vrefn, the corresponding illuminating element 彳Dn is turned on to emit light of a corresponding color, and the illuminating element Dn requiring a high potential reference 唬vrefn is not turned on, and vice versa. However, a comparison of temperature changes and conduction is shown in Table i:
