Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a powder dispensing device and a coffee machine using the same. Background Art

[0002] When making Italian coffee, coffee powder needs to be loaded into a brewing chamber with a filter. In a fully automatic coffee machine, this process is automatically completed by the machine. Since the brewing head needs to be extended into the brewing chamber to form a closed space after the powder is loaded, the coffee brewing can be completed, so the powder loading position must avoid the brewing head space range. In the existing technology, for example, patent document CN102028408B discloses a solution for realizing the two positions of powder loading and brewing by rotating the brewing chamber, while patent document CN117017065A discloses that the above purpose is achieved by translating the brewing chamber. These two solutions are complex in structure due to the multiple action mechanisms in the brewing chamber. The solution disclosed in patent document CN106859344 B is to rotate the powder outlet device longitudinally (horizontally in the direction of the rotating axis) to avoid the brewing head. The problem with this solution is that the range of avoiding air is small, and there is a large gap between the powder outlet device and the powder outlet, and the coffee powder is easy to leak out. In the above three solutions, the powder outlet of the coffee machine is always in an open state, and residual powder is easy to fall out. The water vapor in the brewing process enters the powder outlet channel, causing the coffee powder to become damp and sticky, thereby affecting the taste of the coffee. Utility Model Content
