The detergent is stored in the liquid storage chamber 101, and the capacity of the liquid storage chamber 101 can provide the amount of detergent required for multiple laundry washings, for example, 5 times, 10 times, 20 times, 50 times, 100 times, and the like. The detergent in the liquid storage chamber 101 can flow into the injection chamber 102 through the flow channel 103 .

It should be noted that the detergent is in a liquid state, which can be a liquid with a relatively high viscosity, such as laundry detergent, softener, etc., or a liquid with a relatively low viscosity, such as a disinfectant.

The pressing mechanism is used to close the overflow channel 103 . The pressing mechanism can move relative to the box body 1 , and the pressing mechanism can switch from a closed state of closing the flow passage 103 to an open state of opening the flow passage 103 under the action of an external force. That is, the pressing mechanism can selectively close or open the flow passage 103 .

It can be understood that the pressing mechanism can be movably connected to the box body 1 , and can also be movably connected to other structures other than the box body 1 .

It should be noted that the external force refers to an acting force outside the clothes treating apparatus, for example, an acting force exerted by a user.

When no detergent needs to be dispensed into the dispensing cavity 102 , the pressing mechanism is in a state of closing the overflow channel 103 , that is, the pressing mechanism is in a closed state of closing the overflow channel 103 by default. When it is necessary to release the detergent to the dispensing chamber 102, the pressing mechanism is forced to switch the pressing mechanism from the closed state of closing the overflow channel 103 to the open state of opening the overflow channel 103, and the detergent in the liquid storage chamber 101 passes through the circulation The channel 103 flows into the injection cavity 102 . It should be noted that the user can control the time that the pressing mechanism is in the open state according to the required amount of detergent. When the amount of detergent is sufficient for a single washing of clothes, the pressing mechanism is placed in the closed state of closing the overflow channel 103, that is, Can. That is to say, the detergent put into the dispensing cavity 102 is the detergent required for a single wash of laundry.

After the incoming water flow enters the dispensing cavity 102 , the incoming water flow carries the detergent out of the dispensing cavity 102 .

The dispenser box of the embodiment of the present application does not need to use a suction pump to extract the detergent quantitatively, and manually operates the pressing mechanism to realize the on-demand dispensing of the detergent.
