Below in conjunction with accompanying drawing the utility model is elaborated.

See also Fig. 1, shown in Figure 2, be stereo appearance figure of the present utility model, three-dimensional exploded view.As shown in the figure, be provided with a minute surface 11, a plurality of button 12 and two metal temperature elements 13 on watchcase 1 surface, and be equipped with the circuit board 2 of tool LCD 21 and seven-segment display 22 in inside, and the wire-like temperature element 13 that is exposed above watchcase 1 is not held and is positioned at watchcase 1 inside, LCD 21 and seven-segment display 22 then are aligned with minute surface 11 belows respectively, and below circuit board, be equipped with battery 3, insulcrete 4 and the back of the body 5 activities of cover in regular turn and be engaged in watchcase 1 bottom and locate, constitute integral body of the present utility model with this.

See also Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is outside equipped with at watchcase 1 can be for setting and adjust the button 12 that function is used, watchcase 1 inside then is provided with time showing and measures the control circuit A that temperature is used, and supply power to input circuit A1 by battery 3, be resent to integrated circuit A2-CPC SDCA103, be connected in display circuit A3 and temperature measurement circuit A4 by integrated circuit-A2 CPC SDCA103 again, wherein the end of this temperature measurement circuit A4 includes and stops counting end A41, charging and counting end A42, and discharge end A43, it is connected to the corresponding end of integrated circuit A2-CPC SDCA103 A44, and the other end of this temperature measurement circuit A4 carries out ground connection after being connected serially to a capacitor A45, wherein with discharge end A43, what A44 connected respectively is thermistor A431 and the reference resistance of temperature measurement circuit A4, constitutes circuit of the present utility model with this.

See also Fig. 1, Fig. 4, Fig. 5, shown in Figure 6, the detection step when the utility model is measured room temperature at ordinary times is:

1, make among the control circuit A integrated circuit A2-CPC SDCA103 by charging and counting end A42 (the charge ﹠amp of temperature measurement circuit A4 by button 12 on the watchcase 1; Count enable) charge to noble potential to capacitor A45, capacitor A45 is discharged to discharge end A43 (discharge) via the thermistor A431 that is subjected to room temperature influence, and charging and counting end A42 (charge ﹠amp; Countenable) begin counting, during to capacitor A45 electronegative potential, stop counting by stopping counting end A41 (count disable), and form first count value.

2, then, from charging and counting end A42 (charge ﹠amp; Count enable) charge to noble potential to capacitor A45, capacitor A45 is discharged to discharge end A44 (discharge) via reference resistance A441, and charging and counting end A42 (charge ﹠amp; Countenable) begin counting, during to capacitor A45 electronegative potential, stop counting by stopping counting end A41 (count disable), and form second count value.

3, first and second just more above-mentioned count value of integrated circuit A2-CPC SDCA103 and converse room temperature is done one with room temperature numerical value by the LCD 21 of display circuit A3 again and is shown.

When the utility model desire is measured body temperature, earlier the temperature element on the watchcase 1 13 is close on the skin of the forehead of human body or oxter, at this moment, the step of carrying out temperature check is:

1, makes charging and counting end A42 (the charge ﹠amp of the integrated circuit A2-CPC SDCA103 of control circuit A by button 12 on the watchcase 1 by temperature measurement circuit A4; Count enable) charge to noble potential to capacitor A45, capacitor A45 is discharged to discharge end A43 (discharge) via the thermistor 431 that is subjected to temperature influence, and charging and counting end A42 (charge; Countenable) begin counting, during to capacitor A45 electronegative potential, stop counting by stopping counting end A41 (countdisable), and form first count value.

3, first and second just more above-mentioned count value of integrated circuit A2-CPC SDCA103 and converse body temperature is done one with body temperature numerical value by the LCD 21 of display circuit A3 again and is shown.

Above-mentioned thermistor A431 is the bigger resistive element of a kind of negative temperature coefficient, so the characteristic that diminishes of thermistor A431 when having temperature and raising, resistance value.

In addition, see also shown in Figure 7, wherein this to be arranged at watchcase 1 upper surface two wire temperature elements 13 also can be the sheet metal contact, and temperature element 13 do not hold and penetrates watchcase 1 inside, uses in order to the numerical value of room temperature or body temperature are sent into watchcase 1 inside influencing thermistor 431.

And the utility model is primarily aimed at and is provided with temperature measurement circuit A4 on the wrist-watch simultaneously, and utilizes temperature element 13 to carry out room temperature and detect or be adjacent to the temperature check that directly detects on the skin of the forehead of human body or oxter and be its feature.
