Abstract
Description
Technical Field
[0001] This utility model relates to the field of beverage preparation technology, and specifically to a brewing device. Background Technology
[0002] A brewing machine is a device used in daily life to brew coffee or beverages. Currently, most brewing machines on the market achieve their extraction function through a drive motor and stirring device or through the air pump's induction and extraction. Their structure is very complex and their cost is relatively high.
[0003] For example, utility model patent CN215583859U discloses a portable beverage maker. In this prior art, beverage preparation materials are added to the brewing chamber, a conduit is inserted into a container (e.g., a water cup), and liquid (e.g., water or milk) is added. Through the cooperation of a suction device and a control valve, air is extracted from the brewing chamber (the control valve is closed at this time). Under atmospheric pressure, the liquid in the container is drawn back into the brewing chamber to mix with the beverage preparation materials. Then, the suction is stopped, the control valve is opened, and the brewing chamber is connected to the atmosphere through a return air pipe. The liquid in the brewing chamber flows downwards back into the container. By continuously controlling the start and stop of the suction device and the opening and closing of the control valve, the liquid continuously flows back and forth between the brewing chamber and the container, thereby mixing the liquid with the beverage preparation materials to prepare the beverage. However, this prior art has a very complex structure, high cost, low efficiency in beverage preparation, and insufficient mixing of the liquid with the beverage preparation materials.
[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

This configuration facilitates loading the brewing ingredients into the food container cavity through the food loading opening.
[0012] According to the above scheme, a second sealing ring is fixed on the second cover for sealing with the food loading opening. This design prevents the food from falling out and sticking to the first container when tilted, thus avoiding incomplete extraction.
[0013] According to the above scheme, the liquid receiving cavity is provided with a liquid loading opening, and the liquid loading opening is provided with a removable first cover. This arrangement facilitates the loading of the brewing liquid into the liquid receiving cavity through the liquid loading opening.
[0014] According to the above scheme, a first sealing ring is fixed on the first cover for sealing with the liquid loading opening. This design prevents liquid leakage during pouring and extraction.
[0015] According to the above scheme, a control board is installed inside the power chamber, and the control board is electrically connected; the control board is electrically connected to the power pump; buttons are provided on the control board, and control keys are provided on the base, with the control keys corresponding to the buttons. This arrangement makes operation convenient.
