The main control unit receives the treatment parameters and controls according to the treatment parameters: in the cold therapy mode, the input end of the electromagnetic water valve is controlled to be connected to the outlet of the refrigeration unit, the first circuit is connected, the refrigeration unit is controlled to work, the pump body drives the liquid to flow in the first circuit, flows through the refrigeration unit to cool down, and then the low-temperature liquid flows through the water bag, directly contacts the target object, performs energy exchange, and realizes cold therapy; in the heat therapy mode, the input end of the electromagnetic water valve is controlled to be connected to the outlet of the heating unit, the second circuit is connected, the heating unit is controlled to work, the pump body drives the liquid to flow in the second circuit, flows through the heating unit to cool down, and then the high-temperature liquid flows through the water bag, directly contacts the target object, performs energy exchange, and realizes heat therapy. Thereby, the hot and cold modes can be quickly switched to perform alternating hot and cold treatment.
