The temperature control circuit 400 and the heat generating module 100 are connected by the FPC connection circuit, so that the temperature control circuit can be preferably applied to an apparatus in which a housing is bent, such as a massager.

For example, if the temperature control circuit is applied to a massager.

The lithium battery is used as an external power supply, the lithium battery can be used for storing electric energy, the service life is long, and the temperature control circuit is more convenient and flexible to apply.

In one embodiment, the first switching device is an NMOS transistor, and the second switching device is a PMOS transistor. The temperature control module 400 and the FPC connection circuit 500 respectively use NMOS tubes and PMOS tubes as switching devices in the circuit, the conduction speed in the circuit is high, and the accuracy and the stability of the temperature control circuit are improved.

Specifically, the temperature acquisition module 200 acquires the heating module 100 that heats after being powered on, acquires a temperature signal of the heating module 100, and transmits the temperature signal to the main control module 300. The main control module 300 compares the temperature signal with a preset threshold. The preset threshold value is a temperature range conforming to human body temperature sense, and the preset threshold value can be adjusted and set correspondingly according to different use conditions.

If the temperature signal is greater than the preset threshold, the HEAT pin of the main control module 300 inputs a low level to the temperature control module 400. The gate of the first switching device M2 of the temperature control module 400 receives a low level, so the first switching device M2 is not conductive, and the FPC connection circuit 500 connected to the temperature control module 400 is not conductive. Since neither the temperature control module 400 nor the FPC connection circuit 500 is turned on, the heat generating module 100 has no input voltage and cannot be powered on to generate heat. After the heat generating module 100 is not heated, the temperature signal is correspondingly reduced. If the temperature signal is smaller than the preset threshold, the HEAT pin of the main control module 300 inputs a high level to the temperature control module 400. When the gate of the first switching device M2 of the temperature control module 400 receives a high level, the path between the gate and the drain of the first switching device M2 is turned on, so that the temperature control module 400 is turned on and the FPC connection circuit 500 connected to the temperature control module 400 is also turned on. Since the temperature control module 400 and the FPC connection circuit 500 are both turned on, the heat generating module 100 obtains an input voltage, and is electrically powered on to generate heat, and the temperature signal is correspondingly increased.

The temperature control circuit of the present invention collects the temperature of the heating module 100, and outputs a high level or a low level to the temperature control module 400 through the main control module 300 according to the temperature signal, so as to adjust the operating state of the heating module 100. If the temperature of the heating module 100 is too high, the heating is suspended until the temperature is reduced, and if the temperature of the heating module 100 is too low, the heating is powered on and heated until the temperature is increased, so that the temperature of the heating module 100 is maintained at the preset threshold value, and better use experience is provided for a user.
