step two, temperature control: the temperature sensing range of the first temperature sensor is 30-45 ℃, the temperature sensing range of the second temperature sensor is less than or equal to 30 ℃, the first temperature sensor and the second temperature sensor are used for respectively detecting the positions of the soft water outlet and the sterilized water outlet and generating temperature signals, then the temperature signals are fed back to the controller, the controller receives the temperature signals and then controls the opening and closing of the soft water delivery pump, the sterilized water delivery pump and the switch valve, so that the control of the water temperature in the soft water outlet pipe and the sterilized water return pipe is realized, the temperature of the soft water for the operation of the sterilizer is reduced and then the soft water returns to the sterilizer through the sterilized water return pipe for recycling, and the soft water for cleaning the instruments is conveyed out of the heat exchange component through the soft water outlet pipe after the temperature of the soft water is increased.
10. The method for recycling medical device decontaminating water according to claim 9, wherein: also comprises the following steps of (1) preparing,
step three, supplying soft water to the sterilizer: the low liquid level sensor feeds back a low liquid level signal to the controller after detecting that the liquid level in the storage tank reaches a set value, the controller controls the soft water replenishing pump to be started after receiving the low liquid level signal, and the soft water in the soft water inlet pipe flows into the storage tank through the soft water replenishing pipe, so that the soft water is replenished to the sterilizer;
step four, stopping supplying soft water to the sterilizer: and after the high liquid level sensor detects that the liquid level in the storage tank reaches a set value, the controller feeds back a high liquid level signal to the controller, and after receiving the high liquid level signal, the controller controls the soft water replenishing pump to be closed, and stops replenishing soft water to the storage tank by using the soft water replenishing pipe.
