AI Technical Summary
In existing coffee machines, after the water pump is turned off, the remaining coffee liquid in the coffee channel flows out in a discontinuous dripping manner, causing leakage, which affects the user experience and results in coffee waste.
A coffee drip prevention structure was designed. By setting a spray nozzle in the coffee outlet component, the pressure of the coffee liquid at the spray nozzle is increased, and it is sprayed into the liquid outlet chamber. After the water pump is turned off, the pressure decreases, and the dripping coffee liquid slides into the waste liquid chute for collection.
It effectively prevents coffee dripping, ensures sufficient coffee dispensing, improves user experience, and avoids unnecessary waste.
