Extraction device of pressure-type coffee machine

Abstract

The invention relates to an extraction device of a pressure-type coffee machine, comprising a pressing component driven by a handle and capable of moving up and down. An effluent pressure block is mounted at the bottom of the pressing component; a water inlet is extensionally arranged upward in the middle of the effluent pressure block; the coffee machine is provided with a fixed base at the lower part of the effluent pressure block; the fixed base is internally provided with a coffee collector and a filter screen; an inner cavity is arranged at the bottom of the effluent pressure block; the inner cavity is provided with an auxiliary pressure block capable of being moved downward by water pressure; a limit device for restricting the maximum downward-moving distance of the auxiliary pressure block is arranged between the effluent pressure block and the auxiliary pressure block; a water inlet hole is arranged in the middle of the auxiliary pressure block; a peripheral groove is arranged at the periphery of the auxiliary pressure block and sleeved with a water distribution sealing ring; a groove and a rubber ring are arranged at the bottom of the auxiliary pressure block; the position of the rubber ring corresponds to that of a flange on the filter screen; and the inner side at the bottom of the auxiliary pressure block surrounded by grooves and the filter screen form a coffee extraction cavity together. The product is simple in structure and convenient to operate and saves power.

Description

technical field [0001] The invention relates to a pressure coffee machine, in particular to an extraction device of the pressure coffee machine. Background technique [0002] Existing pressure-type coffee machines all use high-pressure extraction systems. During operation, a relatively large pressure is required to press the outlet pressure block tightly on the fixed seat to form a good seal, and there will be no leakage during high-pressure extraction. However, in order to obtain such a large pressure, it is necessary for the user to use a relatively large force to press down the water outlet pressure block during operation, which is more difficult during operation. In order to make the source of force easier, another solution is to make the force arm very long, but this is not only a waste of material and space, but also due to the existence of the force arm, it leads to the existence of component forces, which makes the force action more complicated , The structure needs...

[0002] Existing pressure-type coffee machines all use high-pressure extraction systems. During operation, a relatively large pressure is required to press the outlet pressure block tightly on the fixed seat to form a good seal, and there will be no leakage during high-pressure extraction. However, in order to obtain such a large pressure, for the user, it is necessary to spend a relatively large amount of force to press down the water outlet pressure block during operation, and it is more difficult to operate.

In order to make the source of force easier, another solution is to make the force arm very long, but this is not only a waste of material and space, but also due to the existence of the force arm, it leads to the existence of component forces, which makes the force action more complicated , the structure needs to consider the effect of component force, which has great limitations on design and processing. In addition, if the force arm is designed to be longer, it will also affect the overall coordination of the coffee machine, and the visual effect of the whole machine will also deteriorate.
