Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, especially the technical field of liquid storage and dispensing mechanisms. Background Art

[0002] The traditional method for adding detergent to electrical washing devices such as washing machines and dishwashers is that the user first stores the detergent in a designated container, and then the electrical washing device flushes the detergent into the washing chamber through water flushing or other mechanical methods according to the washing process. This design results in the amount of detergent dispensed depending on the randomness of the user's operation, and the user needs to add detergent to the container during each washing process (the operation is rather troublesome).

[0003] Currently, more and more electrical washing devices choose to apply dispensers that can automatically dispense detergent, such as the dispenser box, detergent dispensing device and washing machine with the publication number CN109898290B, the detergent dispenser and washing device with the publication number CN214193820U, and the automatic detergent dispensing device for a washing machine with the publication number CN104047146A. Such dispensers allow users to pour a large amount of detergent into them at one time before work, and can automatically adjust the amount of detergent dispensed according to the type and quantity of the laundry during work. This can not only reduce the trouble of user operation, but also improve the accuracy of detergent dispensing to ensure thorough cleaning or reduce waste of detergent.

[0004] As Figure 1 shown, the liquid storage box a of the traditional dispenser usually has a ventilation structure b and a sealing structure c. Among them, the ventilation structure b is used to let air in during automatic dispensing to prevent the liquid storage box a from being sucked in; the sealing structure c can seal the liquid storage box a when it is not connected to the automatic dispensing component, so as to prevent the detergent from flowing out of the liquid storage box a. However, on the one hand, such a liquid storage box a cannot be used once and discarded due to the high processing cost, and on the other hand, the detergent is very likely to leak from the ventilation structure b during transportation. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems in the prior art, and propose a liquid storage and dispensing mechanism, in which the liquid storage box can be used once and discarded and is not easy to leak detergent.

[0006] To achieve the above purpose, the utility model proposes a liquid storage and dispensing mechanism, including a liquid storage box and an automatic dispensing component. The box opening of the liquid storage box is sealed by a sealing structure, and the automatic dispensing component can push open the sealing structure through a protruding part. The protruding part has a gas channel for maintaining the air pressure balance inside and outside the liquid storage box and a liquid channel for dispensing detergent to the electrical washing device.

[0007] Preferably, the gas channel and the liquid channel are sealed with the box opening through the same sealing structure.

[0008] Preferably, the protruding part separates the gas channel and the liquid channel through a partition board.

[0009] Preferably, one end of the gas channel is provided with an air inlet connected to the atmosphere, and the other end is provided with an air outlet that can communicate with the liquid storage cavity of the liquid storage box when the protruding part pushes open the sealing structure. One end of the liquid channel is connected to the dispensing cavity of the automatic dispensing component, and the other end is provided with a liquid inlet that can communicate with the liquid storage cavity of the liquid storage box when the protruding part pushes open the sealing structure.

[0010] Preferably, the air outlet and the liquid inlet are isolated by a sealing ring.

[0011] Preferably, an air outlet check valve is installed at the air outlet.

[0012] Preferably, the air outlet check valve is located in the air outlet valve cavity, and the opening of the air outlet valve cavity faces downward.

[0013] Preferably, a collar is sleeved outside the protruding part, and the collar can block the air outlet and the liquid inlet when the protruding part is not inserted into the liquid storage box.

[0014] Preferably, an air inlet check valve is installed at the air inlet.

[0015] Preferably, both the air outlet and the liquid inlet are located at the free end of the protruding part.

[0016] Advantages of the present utility model:

[0017] 1) By respectively adding a gas channel and a liquid channel in the protruding part of the automatic dispensing component, during the process of using the protruding part to push open the sealing structure to open the box opening of the liquid storage box, on the one hand, gas can automatically enter the liquid storage cavity along the gas channel to keep the internal and external air pressures of the liquid storage box balanced, avoiding the liquid storage box from being sucked and deformed. On the other hand, the detergent can flow into the electric washing equipment along the liquid channel under the action of external suction to achieve the automatic dispensing function;

[0018] 2) The liquid storage box has a simple structure, low cost, and can be used once and then discarded;

[0019] 3) The liquid storage box has no air-permeable structure and is in a fully sealed state during transportation, which can fundamentally prevent the detergent from leaking out through the air-permeable port.
