Description

Pneumatic coffee pot Technical Field The utility model relates to the field of coffee pots, in particular to a pneumatic coffee pot. Background The structure of the coffee pot can be referred to as a Chinese patent of the utility model with the application number of CN202320587747.6 and the name of the combined coffee pot with the bubble removing structure. The pressure reducing valve of the existing coffee pot is used for reducing the pressure of a carbon dioxide gas cylinder from 60bar to 9bar, the gas release mode of the pressure reducing valve is a knob or pressing gas outlet, and the released gas enters the coffee pot through quick-connection equipment and lifts the pressure in the coffee pot, so that hot water in the coffee pot is high-pressure through coffee powder, and coffee concentrate is extracted. And releasing the pressure in the coffee pot through the pressure release equipment after the extraction is finished. The volume of current coffee pot relief pressure valve is great relatively, does not make into an organic whole with the relief valve, and the mode of knob release pressure is comparatively loaded down with trivial details, and the mode of pressing release uses the strength great relatively, and accessory quantity is more relatively, and the operation is inconvenient, does not accord with ergonomic.
