[0050] Everything else is the same as in Example 1.
[0051] The working process of this embodiment:
[0052] like Figure 13 As shown, when detergent needs to be added, the third liquid valve 19 is opened and the fourth liquid valve 23 is closed. At this time, the water flowing from the water source into the eighth liquid pipe 17 first enters the Venturi tube 18 through the small end, then flows out of the Venturi tube 18 through the large end, and finally enters the interior of the washing chamber through the seventh liquid pipe 16. During this process, the detergent, under the negative pressure of the Venturi tube 18, first enters the Venturi tube 18 through the negative pressure end through the sixth liquid pipe 15 and mixes with the water flow to be discharged into the washing chamber. In addition, the detergent can also mix with the accumulated water in the second liquid exchange chamber 25; the flow sensor 20 can monitor the flow rate of the liquid entering the Venturi tube 18 through the negative pressure end, thereby improving the accuracy of detergent dosage.
[0053] like Figure 14 As shown, when it is necessary to rinse the internal structure of the dispenser body 2, the third liquid valve 19 is closed and the fourth liquid valve 23 is opened. At this time, the water flow into the ninth liquid pipe 21 is divided into two streams. One stream flows into the washing chamber through the seventh liquid pipe 16 and rinses the flow sensor 20 and the venturi tube 18, while the other stream flows into the washing chamber through the sixth liquid pipe 15 and the tenth liquid pipe 22 and rinses the second liquid exchange chamber 25 and the second inner sealing structure 24. In addition, the user can also remove the liquid storage box 1 directly from the dispenser body 2 for cleaning.
