Abstract: A temperature control circuit for two heating devices respectively provided with a heater and a sensing wire. The sensing wires' ends are respectively connected to a diode. The two diodes' polarity is opposite to that of the sensing wires' connecting ends. Another ends of the sensing wires are connected to a capacitor to form a resistor-capacitor circuit. The heater wires are connected to a diode respectively and then a bi-directional thyristor. The two diodes' polarity is opposite to that of the heater wires' connecting ends. Thereby, the heater wires can be heated up respectively by the positive and negative half-periods of alternating current. When phase shifts occur because of the heater wires' temperature change, the sensing wires can control the bi-directional thyristor via a controller so that the positive or negative half-period are not triggered. Therefore, the heater wires' heating temperatures can be controlled individually.

Abstract: A safety control structure for heater wire comprises a switch, a first heating wire, a second heating wire, and an over-current protection element, which are sequentially connected in series connection. An insulation and fusible layer is interposed between the first heating wire and the second heating wire. Accordingly, under normal condition, the switch is triggered by triggering the circuit, so as to have the first heating wire and the second heating wire then be heated up within a preset temperature range. When the first heating wire and the second heating wire produce exceptionally high temperatures to fuse the insulation and fusible layer, the current is increased instantaneously because the first heating wire and the second heating wire are short-circuited. Therefore, the circuit is interrupted by the over-current protection element to show a broken circuit status in order to stop heating up.

A first and second areas are adjacently disposed on top of the first hot compress pad and a first heating device is disposed in the first area. A third and fourth areas are adjacently disposed on top of the second hot compress pad and a second heating device is disposed in the fourth area. When the first or the second hot compress pad is folded in half, the two halves thereof are coupled by the first or the second positioning element, so that the first and the second areas or the third and the fourth areas are overlapped with each other. Thereby, the two hot compress pads are formed which can be used independently.

Abstract: A temperature control method for a heating line comprises steps of: inputting continuous and changing pulse wave signals produced by the heating of a heating wire and reference pulse wave signals into a And-gate; utilizing the And-gate to obtain continuous synthesized pulse wave signals each of which has a pulse width that spans from a time point in which a logic high state begins to a time point in which the logic high state terminates; and controlling the control circuit to stop the heating of the heating wire when the time point in which the logic high state begins moves in relative to the time point in which the logic high state terminates and the pulse width of the synthesized pulse wave signals reaches a value preset by the processor, so as to keep the temperature within a preset and prevent overheat.

Abstract: A heating structure and method for preventing overheat of a heating line, where the heating line includes a sensing line and a heating wire in parallel connection. The sensing line has one end connected with a processor. The heating wire has one end connected sequentially with an over-current protection element and an alternating current power's one polarity and has another end connected sequentially with a switch and the alternating current power's another polarity. The processor controls the trigger circuit to trigger the switch to be in conducting condition. Thereby, under normal condition, the heating of the heating wire is in half-wave form. When abnormal signals from the sensing line are detected by the processor, the switch is controlled to let the alternating current pass through the heating wire in full-wave form to increase the current instantaneously and disconnect the over-current protection element to stop the heating.
