  • Patent number: 11980317
    Abstract: The present disclosure provides a beverage dispenser with an identification device and an operating method of the beverage dispenser. The beverage dispenser with an identification device comprises a body, the identification device installed on the body, and the heating device installed on the body and electrically connected to the identification device. It may realize the heating of the beverage in the pot via the heating device after the identification device identifies the type of pot and after the identification device turns on the heating device, or the disconnection of the heating device by the identification device. According to the type of pot identified, the beverage dispenser with an identification device may heat the beverage in a pot without a heat preservation function, or not heat a pot with a heat preservation function and use the pot itself for heat preservation.

  • Patent number: 11980318
    Abstract: The present disclosure discloses a mocha pot combined device and method for using the same. By combining the pot body with the base, setting a temperature control device and a stirring device in the base, setting a detachable upper pot and lower pot in the pot body, and setting a filter between the upper pot and lower pot, water is stored in the lower pot and heated and then flows into the filter to mix with coffee powder, and it is then extracted to form coffee and flows into the upper pot for storage. The stirring device ensures that the water in the lower pot is evenly heated and reaches the required temperature quickly, and the temperature control device ensures precise control of the water temperature and heating time, thereby realizing automatic control of the coffee-making process, guaranteeing the taste of the coffee, and shortening the coffee brewing time.
