In the embodiment of the present invention, the temperature sensor 10 may be a thermocouple, a thermistor, or the like, and the embodiment of the present invention does not limit the type of the temperature sensor 10; the switch 10 may be a relay, for example, a DC 5V relay, or may be another electrically controlled switch, and the embodiment of the present invention does not limit the kind of the switch 10.
Further, as shown in fig. 1, the temperature control device 1 may further include a heater wire control switch 31, for example, an AC 200V relay, corresponding to the switch 30. The switch 30 is used to control the heating wire control switch 31, and thus the heating unit 20 or the heating wire (not shown, such as at least the groove provided on the inner wall of the heating apparatus 2 in fig. 4 and 7) in the heating unit 20 is turned on or off by the heating wire control switch 31.

For example, the predetermined threshold may be 1.5 ℃ when the set temperature is 900 ℃ or higher, and the predetermined threshold may be 3 ℃ when the set temperature is lower than 900 ℃.
In addition, the size of the predetermined threshold is not limited in the embodiments of the present invention, for example, in order to make the temperature control more accurate, thresholds smaller than 1.5 ℃ and 3 ℃ may be set to manage the temperature more finely, or in order to avoid frequent temperature adjustment, thresholds larger than 1.5 ℃ and 3 ℃ may be set to save the cost.
In at least one embodiment, the control unit 40 may read the temperatures measured by the respective temperature sensors 10 at a predetermined frequency, calculate an average value of the detected temperatures in a predetermined time range for each temperature sensor 10, and control the on/off of the respective switches 30 according to the average value of the respective temperature sensors 10.

The embodiment of the present invention does not limit the time range of the frequency of the temperature read by the control unit 40 and the average value calculation, and can be set according to the actual situation.
In at least one embodiment, the heating unit 20 may include at least one set of heating wires. In addition, the number of the heating wires included in each heating unit 20 may be the same or different, and may be set according to actual needs, which is not limited in the embodiment of the present invention.
