Abstract

An electronic patch thermometer consists of a measuring apparatus attaching to or disposing on a targeted object (such as human body skin or a tongue surface, indoor or outdoor, surfaces of a container, water tanks, and the likes) and a receiving apparatus for receiving signals measured by the measuring apparatus. When the receiving apparatus is moved nearby the measuring apparatus and a measuring switch located on the receiving apparatus is pressed, the receiving apparatus generates a magnetic field transmitting to the measuring apparatus to generate electric power required. The measuring apparatus measures and induces temperature signals of the targeted object and transmits the signals by radio waves to the receiving apparatus which reads and displays the temperature value of the targeted object.

Claims

1. An electronic patch thermometer for measuring the temperature of a targeted object, comprising:

a measuring apparatus selectively attaching to or disposing on the targeted object; and

a receiving apparatus for providing a magnetic field to the measuring apparatus and transferring to electric power required by the measuring apparatus receiving temperature signals transmitted from the measuring apparatus in a radio wave fashion and immediately displaying results in the form of numerals, audio alarm and speeches,

wherein the measuring apparatus includes;

a magnetic field induction unit for receiving magnetic field signals and converting to AC electric power for output;

a conversion unit connecting to an output end of the magnetic field induction unit for converting the AC electric power to DC electric power for output;

an induction unit for inducing the temperature of the targeted object;

a data processing unit connecting to an output end of the induction unit for receiving temperature signals of the targeted object induced by the induction unit and processing the signals for output; and

an emission unit connecting to an output end of the data processing unit for receiving the processed signals from the data processing unit and emitting the signals by radio waves.

2. The electronic patch thermometer of claim 1, wherein the measuring apparatus includes a patch which has one side with a temperature induction element located thereon and the other side with a circuit board and an induction coil located thereon, the circuit board having a data processing element, a conversion circuit and an emission end, the conversion circuit converting AC electric power to DC electric power for output.

3. The electronic patch thermometer of claim 1, wherein the receiving apparatus has a display screen, a measuring switch and a circuit located therein.

4. The electronic patch thermometer of claim 1, wherein the patch measuring apparatus is attached to one side of a pacifier, the temperature induction element being located in a sucking section of a pacifier through an extending rod.

5. The electronic patch thermometer of claim 1, wherein the patch measuring apparatus is selectively attached to an inner wall or a bottom of a bathtub, or floated o water surface to measure water temperature in the bathtub.

6. The electronic patch thermometer of claim 1, wherein the patch measuring apparatus is attached to a feeding bottle to allow a temperature induction element or an induction unit located in the measuring apparatus to measure water temperature filled in the feeding bottle.

7. The electronic patch thermometer of claim 1, wherein the magnetic field induction unit includes a magnetic field induction device and a high frequency electric coupling coil, the magnetic field induction device being formed by a coil.

8. The electronic patch thermometer of claim 1, wherein the induction unit is selectively a thermistor or a thermal induction element.

9. The electronic patch thermometer of claim 1, wherein the data processing unit is a microprocessor chip.

10. An electronic patch thermometer for measuring the temperature of a targeted object, comprising:

a measuring apparatus selectively attaching to or disposing on the targeted object; and

a receiving apparatus for providing a magnetic field to the measuring apparatus and transferring to electric power required by the measuring apparatus receiving temperature signals transmitted from the measuring apparatus in radio wave fashion and immediately displaying results in a form of numerals, audio alarming or speeches, wherein the receiving apparatus includes;

a power supply unit;

a magnetic field generation unit connecting to an output end of the power supply unit for converting DC electric power to a magnetic field for emitting to the measuring apparatus;

a receiving unit receiving signals emitted from the measuring apparatus; and

a control unit connecting to an output end of the receiving unit for receiving signals output from the receiving unit, and processing and outputting the signals in the form of numerical data, speeches or audio alarm.

11. The electronic patch thermometer of claim 10, wherein the power supply unit is a battery or city power.

12. The electronic patch thermometer of claim 10, wherein the magnetic field generation unit includes a high frequency electric oscillation unit and a magnetic field generator, the magnetic field generator being formed by a coil, the high frequency electric oscillation unit converting DC electric power to AC electric power for output.

13. The electronic patch thermometer of claim 10 further having a display unit located in the receiving apparatus and connected to an output end of the control unit for displaying the temperature value.

14. The electronic patch thermometer of claim 10 further having an output unit located in the receiving apparatus and being selectively a buzzer or a speaker.

15. The electronic patch thermometer of claim 10, wherein when the receiving apparatus is moved beyond an effective distance of a magnetic field, the measuring apparatus is not induced and cutoff from electric power and shutdown.
