Since the heating member 130 is provided in the first accommodating chamber 111, the air in the first accommodating chamber 111 is heated by the heating member 130; then, the heated air is sent into the thermostat 200 through the fan 120, so that the temperature between the air guide body 110 and the thermostat 200 is directly transferred by convection, which is beneficial to improving the temperature rise efficiency in the thermostat 200.
