Specifically, in the step S2, the step of detecting the detergent concentration by the optical transceiver includes:

Wherein the first detection data corresponds to the viscosity of the detergent, and the corresponding relationship is stored in the control module;

Specifically, first, when the detergent is not delivered, the emitting portion of the optical transceiver emits a bundle of detecting light that is irradiated to the transparent portion of the infusion tube and provided with the optical transceiver at a certain angle and intensity, and is configured by the optical transceiver. The receiving portion receives the detection light reflected back from the transparent portion of the infusion line, and measures a first reflection intensity and/or a first reflection angle of the detection light received by the receiving portion by a measurement module provided in the optical transceiver.

Then, through the transmitting portion in the optical transceiver, a bundle of detection light that is irradiated to the transparent portion of the infusion line and provided with the optical transceiver is emitted at the same angle and intensity as described above, and at this time in the infusion line The transparent portion is filled with the detergent, and the light emitted by the emitting portion is irradiated onto the detergent-filled infusion tube, and the detecting portion reflected by the transparent portion of the infusion tube is received by the receiving portion in the optical transceiver, and A measurement module disposed in the optical transceiver measures a second reflection intensity and/or a second reflection angle of the detection light received by the receiving portion.

Step S5; if it is replaced, step S2 is performed.

Or, when the detergent in the liquid storage tank has not been replaced, continue to determine whether the distance from the last use is within the set time, and if so, the concentration of the detergent in the liquid storage tank is detected before reading, and step S5; If no, step S2 is performed.
