Description

Technical Field

[0001] This utility model relates to the field of coffee making equipment technology, and in particular to a flow-stopping structure and a coffee machine. Background Technology

[0002] Existing coffee machines typically include a liquid reservoir, a heating element, and an extraction element. Ground coffee beans are placed in the extraction element, the liquid reservoir supplies liquid to the extraction element, and the heating element heats the liquid. When it is necessary to replenish or replace the liquid in the liquid reservoir, the user can detach the liquid reservoir from the coffee machine. A flow-stopping structure can be installed at the interface between the liquid reservoir and the heating element. When the liquid reservoir is detached from the coffee machine, the flow-stopping structure can block the liquid in both the liquid reservoir and the heating element to prevent liquid from flowing out. In the past, flow-stopping structures mostly used switch valves. Users needed to first turn the switch valve to disconnect the fluid passage before detaching the liquid reservoir from the heating element. However, during the user's operation, there may be omissions, and the liquid will leak out, which is inconvenient and cannot meet the user's needs. Utility Model Content

The head end of the first support 121 is close to the liquid inlet 140, and the tail end of the first support 121 is close to the liquid outlet 150. The tail end of the first elastic element abuts against one side wall of the first protrusion 122, so that the other side wall of the first protrusion 122 abuts against the side wall of the protruding ring 160 to block the valve port 170.
