Portable espresso machine with grinding function

Abstract

The invention discloses a portable espresso machine with a grinding function. The machine comprises a cylinder, a grinding assembly and a screw rod assembly, wherein the grinding assembly is detachably mounted inside the cylinder, and the screw rod assembly is used for driving hot water to flow through coffee powder to achieve extraction and driving the grinding assembly to conduct grinding and detachably mounted at the upper end of the cylinder; during grinding, the grinding assembly is mounted inside the cylinder, and the upper end of a rotating shaft of the grinding assembly is in transmission connection with a piston of the screw rod assembly through a connecting structure; during the extraction, the grinding assembly is removed from the interior of the cylinder. The espresso machine integrates the functions of grinding coffee beans and extracting the coffee powder, the grinding assembly and the screw rod assembly are both detachably connected with the cylinder, the espresso machine is convenient to disassemble and carry, simple in structure, small in size and convenient to use, and can meet the requirements of people for outdoor carrying and usage and be suitable for making espresso anytime and anywhere.

Description

technical field [0001] The invention relates to a coffee machine, in particular to a portable espresso coffee machine with a grinding function. Background technique [0002] Espresso (Espresso) is a type of coffee with a strong taste. It is made by hot water at about 92°C, and the coffee is extracted by high pressure (9bar) ​​through ground coffee powder. Existing coffee machines for making espresso are generally large-scale machines, which are extracted by pressure generated by water in an electric heating boiler. This machine is bulky and difficult to carry, and cannot meet the requirements of people to drink at any time. At present, there are also some portable espresso machines on the market. The common ones are pump-type coffee machines. Although the coffee machine can realize the high-pressure extraction function, it does not have a grinding mechanism and cannot realize the grinding of coffee beans. Contents of the invention [0003] The technical problem to be sol...

Problems solved by technology

Existing coffee machines for making espresso are generally large-scale machines, which are extracted through the pressure generated by the water in the electric heating boiler. This kind of machine is bulky and not easy to carry, and cannot meet the requirements of people to drink at any time

At present, there are also some portable espresso machines on the market. The common ones are pump-type coffee machines. Espresso coffee uses freshly ground coffee beans to extract a richer coffee aroma, but the current pump-type coffee machines Although the coffee machine can realize the high-pressure extraction function, it does not have a grinding mechanism and cannot realize the grinding of coffee beans
