The shape of the blocking member 300 should be matched with the shape of the second cavity 120 so that the blocking member 300 can move up and down in the second cavity 120. Meanwhile, after the blocking member 300 moves to the liquid passing groove 700, the liquid passing groove 700 should be completely sealed. In another embodiment, in order to improve the sealing effect of the barrier 300 on the liquid passing groove 700, rubber may be provided at the contact portion between the barrier 300 and the liquid passing groove 700 to improve the contact sealing degree therebetween.

The automatic detergent dispensing system comprises a detergent box 100, a barrier 300 and a first driving device 400, wherein the detergent box 100 is communicated with a water inlet of the washing machine, so that clean water can enter the detergent box 100. The mesh-shaped baffle part 200 is arranged in the detergent box 100, the first cavity 110 is formed between the interior of the baffle part 200 and the bottom of the detergent box 100, the whole detergent box 100 is used for placing laundry detergent, the first cavity 110 can be used for placing laundry detergent, water is injected into the detergent box 100 to dissolve the laundry detergent in the first cavity 110, and the dissolved laundry detergent solution and the dissolved laundry detergent can flow into a washing area of the washing machine from the liquid passing groove 700, so that the putting system can put the laundry detergent and also put the laundry detergent, and the compatibility is high.
