[0024] The working principle of this embodiment is as follows: The connector 22 is connected to an external water source. First, the laundry detergent dispensing cap 24 is opened, and the laundry detergent is injected into the laundry detergent box 5 through the connecting pipe 23 and the injection pipe 10. After the filling is completed, the laundry detergent dispensing cap 24 is closed and the container is ready for use. When in use, connect the power supply to the washing machine and start it. First, start the motor 7 through the controller 25. Driven by the motor 7, the stirring rod 8 rotates, which in turn drives the stirring blade 9 to rotate, thereby stirring the laundry detergent in the detergent box 5 evenly. Then, the washing machine sends a dispensing request to the controller 25 according to the weight of the clothes or the washing program. The controller 25 calculates the required amount of detergent and then starts the first peristaltic pump 16 or the second peristaltic pump 17 according to the usage requirements. Under the action of the first peristaltic pump 16 or the second peristaltic pump 17, the detergent is input into the first outlet pipe 11, and then input into the three-way single-pass valve 19 through the three-way pipe 13, the first inlet pipe 14 or the second inlet pipe 15, and the second outlet pipe 18. Simultaneously, water pump 21 is started, and clean water is input into the three-way single-pass valve 19 through water pump 21, so that clean water and laundry detergent are mixed in the three-way single-pass valve 19. The mixed laundry detergent is input into the first mixing tank 2 or the second mixing tank 3 through water pipe 20 to complete the automatic dispensing of laundry detergent. At the same time, the amount of laundry detergent dispensed is monitored by liquid flow meter 12. When the set amount is reached, the information is transmitted to controller 25 for processing. Controller 25 controls the first peristaltic pump 16 and the second peristaltic pump 17 to stop working.
