[0032] Among them, the redirection component also includes a guide slide 305 and a strong magnet 306; the guide slide 305 is opened on the front side of the liquid guide pipe 3; the strong magnet 306 is connected to the inner side of the guide slide 305 by sliding up and down, and the strong magnet 306 is mutually clamped with the slider of the linear module 7.

[0033] Among them, the diversion component also includes a liquid outlet 801 and an adsorption magnet 802; there are two liquid outlets 801, and the two liquid outlets 801 are respectively opened on the left and right sides of the liquid guiding tube 8; the adsorption magnet 802 is fixedly connected to the front side of the liquid guiding tube 8, and the adsorption magnet 802 and the strong magnet 306 are adsorbed to each other.

[0034] Among them, the redirection component also includes a guide plate 803 and a contact head 901; the guide plate 803 is fixedly connected to the upper part of the liquid guide tube 8; the contact head 901 is arranged on the upper part of the pH tester 9, and the water pump inside the acidic waste liquid treatment box 4 and the water pump inside the alkaline waste liquid treatment box 5 are both connected in parallel with the control circuit of the pH tester 9.

At this time, the waste liquid can directly flow along the inclined surface of the sealing plate 308 to the lower part of the liquid guiding pipe 3 and enter the sewer. After the waste liquid treatment is completed, the PH tester 9 no longer generates a signal. At this time, the linear module 7 drives the liquid guiding tube 8 back to the initial position, and the sealing plate 308 automatically resets under the action of the elastic member 309.
