- Many irons on market have installed with a safety device. Most of which are in an electrical conductor type, photoelectric sensing type, capacitor type or roller resistant type, such as the Taiwanese Patent No. 381727 titled “SAFETY CONTROL DEVICE FOR AN IRON”, which disclosed a roller resistant type as a safety control device. Another Taiwanese Patent No. 339787 titled “AN IRON WITH SAFETY CONTROL STRUCTURE” disclosed a photoelectrical conducting type, roller resistant type, and electrical conductor type. However, all of the above-mentioned safety control types require a large bead to roll on a flat and smooth surface which can not hold the bead firmly, thus, the sensitivity may be differed.
- According to the present invention, there is provided a device to detect an iron's position, comprising:
-
- a constant voltage regulator;
- a frequency pick up unit connected to said constant voltage regulator, said frequency pick up unit comprising a resistor and a capacitor, said resistor being connected to said capacitor to retrieve an input frequency signal;
- an integrated circuitry chip connected to said constant voltage regulator, said integrated circuitry chip comprising a frequency producer and a frequency identifier, said frequency producer being connected to said frequency identifier;
- a sensor unit connected to said frequency pick up unit and said integrated circuitry chip, said sensor unit comprising a metal ball and an arc track, said metal ball being placed on said arc track for controlling signal input of said frequency pick up unit depending on the deviation of said metal ball sliding on said arc track; and
- a control unit connected to said frequency identifier of said integrated circuitry chip, said control unit comprising a transistor and a relay, said transistor being connected to said relay, said frequency identifier triggering a signal to change the working mode of said transistor to activate said relay.
- Preferably, said constant voltage regulator comprises a resistor, a rectifier diode, a zener diode, and a capacitor, said resistor being connected to and said rectifier diode for restraining input voltage volume, said rectifier diode rectifying the input voltage, said zener diode limiting the input voltage, and said capacitor filtering the input voltage.
- Preferably, said integrated circuitry chip further comprises a whistler.
- Preferably, said integrated circuitry chip further comprises a light-emitting diode.

FIG. 2 is a circuitry of the present invention. - As shown in
FIGS. 1 and 2 , a preferred embodiment of the present invention comprises aconstant voltage regulator 1, a frequencypick up unit 2, anintegrated circuitry chip 3, asensor unit 4 and acontrol unit 5. - The
constant voltage regulator 1 comprises aresistor 11, arectifier diode 12, azener diode 13, and acapacitor 14. Theresistor 11 is connected to therectifier diode 12 in order to restraint voltage input as to protect therectifier diode 12 from damaging if the voltage has a huge amount input, the voltage then through therectifier diode 12 to output a stable voltage. If the input voltage is larger than predetermined collapsed voltage of thezener diode 13, the output voltage will be limited only the collapsed voltage preset to thezener diode 13, while thecapacitor 14 will filter the voltage received from thezener diode 13 to delete unnecessary signal and output a stable voltage. - The frequency pick up
unit 2 is connected to theconstant voltage regulator 1 and comprises aresistor 21 and acapacitor 22. Theresistor 21 and thecapacitor 22 are connected in series to retrieve the frequency of the input voltage and transmit to the integratedcircuitry chip 3. - The integrated
circuitry chip 3 is connected to theconstant voltage regulator 1 and comprises afrequency producer 31 and afrequency identifier 32. Thefrequency producer 31 produces a frequency and delivers the frequency to thefrequency identifier 32. Thefrequency identifier 32 compares the frequency signal from thefrequency producer 31 with the frequency signal from the frequency pick upunit 2. The integratedcircuitry chip 3 further comprises awhistler 33 and a light-emitting diode (LED) 34 for alert notification. - The
sensor unit 4 is connected to the frequency pick upunit 2 and the integratedcircuitry chip 3, and comprises ametal ball 41 and anarc track 42. Thesensor unit 4 detects the deviation of themetal ball 41 sliding on thearc track 42. This design provides a high sensitivity to detect the position of the iron. - The
control unit 5 is connected to the integratedcircuitry chip 3, and comprises atransistor 51 and arelay 52. When thetransistor 51 is in a saturated status, a power source will be triggered to activate therelay 52. - To operate the present invention, as shown in
FIGS. 1 and 2 , theconstant voltage regulator 1 inputs a voltage to the frequency pick upunit 2, and the frequency pick upunit 2 retrieves the frequency signal of the input voltage. Thesensor unit 4 utilizes the deviation of themetal ball 41 sliding on thearc track 42 to sense the iron's position. The frequency signal of the input voltage is transmitted through thesensor unit 4 to the integratedcircuitry chip 3. This frequency signal will be compared by thefrequency identifier 32 with the frequency signal from thefrequency producer 31 of the integratedcircuitry chip 3. When thefrequency identifier 32 identifies that thefrequency producer 31 is producing a frequency signal different from the input frequency signal, thesensor unit 4 will be in an open status. Thefrequency identifier 32 transmits a signal to thecontrol unit 5, which causes thetransistor 51 in a saturated status to activate therelay 52. When the frequency signal from thefrequency producer 31 is identified the same as of the frequency signal of the input voltage, thesensor unit 4 will be in a short circuit, and thefrequency identifier 32 will transmit a signal to thecontrol unit 5, which causes thetransistor 51 in a working status to activate therelay 52, so that the iron can be detected in a straight or flat status to control the auto shut-down time when the iron is not in use. Thearc track 42 of thesensor unit 4 provides themetal ball 41 to slide thereon and any change of the iron will cause themetal ball 41 to deviate on thearc track 42. This design provides a highly sensitivity of thesensor unit 4 to detect the position of the iron if it is in a straight or flat situation.
