Therefore, on one hand, the human body is cooled by refrigerating, and on the other hand, the refrigerating effect is detected by adopting the technology; the detection is realized at any time.

In order to prevent the document from being unclear, it is necessary to say that the temperature sensor is installed at a position, since the sensor itself is placed on the housing, and if the position is not correctly placed, the temperature to be tested may be the temperature of the housing, so that during installation, attention needs to be paid to the fact that the probe of the sensor can be properly extended out of the housing without affecting wearing comfort. As for the internal wiring connections and the like, they can be laid out according to the prior art (in a limited way without affecting the use and comfort).

In order to further enhance the heat dissipation function, a heat dissipation sheet is arranged above the electronic refrigeration module and is arranged between the refrigeration module and the heat dissipation fan.
