Example 1

As shown in fig. 1 to 10, in the embodiment of the present invention, a detergent dispensing device is described, which includes a storage device 100 and an extraction device 200, wherein the storage device 100 is used for storing detergent in advance, and the extraction device 200 is communicated with the storage device 100 and is used for extracting a fixed amount of detergent from the storage device 100 for dispensing according to a control program.

In this embodiment, the detergent is a liquid detergent.

As shown in fig. 3 to 10, the storage device 100 includes a housing, a cavity 105 for placing a liquid storage box 104 is disposed in the housing, and a conducting structure 103 is disposed in the cavity 105. The conducting structure 103 is tubular, one end of the conducting structure 103 is fixed on the inner wall of the cavity 105, and the other end extends into the cavity 105. In this embodiment, the conducting structure 103 is mounted on the bottom inner wall of the cavity 105, the bottom end of the conducting structure 103 is connected with the inner wall of the cavity 105, and penetrates through the inner wall of the cavity 105 to be communicated with the input end of the extracting device 200 outside the housing, and the top end of the conducting structure 103 is in a needle shape and extends towards the inside of the cavity 105.

The opening of the liquid storage box 104 is provided with a conduction valve, and the conduction valve comprises a valve body arranged at the opening of the liquid storage box 104, a valve core used for opening and closing the opening of the liquid storage box 104 and an elastic piece used for keeping the valve core at a closed position. When the liquid storage box 104 is arranged in the cavity 105, the conducting structure 103 presses the valve core of the conducting valve towards the inside of the liquid storage box 104, so that the elastic piece of the conducting valve is compressed, the valve core is switched to the opening position, and at the moment, the liquid storage box 104 is communicated with the extracting device 200 through the conducting structure 103. When the liquid storage box 104 is taken out, the conducting structure 103 is separated from the conducting valve, the valve core of the conducting valve is restored to the closing position under the action of the elastic piece, and the liquid storage box 104 is closed.

In this embodiment, a sealing member is further disposed between the conducting structure 103 and the valve body of the conducting valve, so as to prevent the detergent from flowing out from the gap between the conducting structure 103 and the conducting valve when the conducting valve is opened.
