The heat dissipation subsystem comprises a constant current driving unit, a first temperature sensor of the disinfection device, a heat dissipation structure and a control unit, and when the heat dissipation structure comprises a fan, the fan is regulated in speed through the constant current driving unit so as to adjust the heat dissipation effect. The heating subsystem comprises a solid-state relay, a second temperature sensor of the disinfection device, a heating element, a temperature control switch and a control unit. The solid-state relay is a normally open relay and is not heated when not receiving a control signal. When the control unit receives the measured temperature detected by the second temperature sensor, the measured temperature is compared with the set temperature, and a control signal is sent to control the opening and closing of the relay. When the relay is closed, a heating loop formed by the alternating current power supply, the heating element, the solid-state relay and the temperature control switch is conducted to heat the containing cavity. In one embodiment, the ultraviolet light source control system and the temperature control system adopt the same constant current driving unit and the same voltage stabilizing unit; the voltage stabilizing unit is a 36V voltage stabilizing unit. The control unit is electrically connected with the upper computer so as to display data, such as ultraviolet light irradiance information and/or temperature information, which needs to be checked by a user, to the user on the upper computer.
