Filtering assembly and capsule coffee making device

Abstract

The invention relates to the technical field of coffee machines, in particular to a filtering assembly. The filtering assembly comprises a filtering screen provided with a plurality of filtering holes. A plurality of bosses are further arranged on the filtering screen. The filtering assembly further comprises a screen cover matched with the filtering screen. The screen cover is provided with a plurality of assembly holes matched with the bosses in shape and in position. The bosses are inserted into the assembly holes in a one-to-one correspondence mode so that the screen cover can be connected with the filtering screen in a matched mode. Besides, gaps exist between the assembly holes and the bosses after the assembly holes and the bosses are rotationally assembled, and the bosses will be higher than the plane of the screen cover. The invention further provides a capsule coffee making device using the filtering assembly. The filtering assembly has the advantages of being simple in manufacturing technology and small in hole diameter, and large making pressure can be provided while it can be guaranteed that coffee liquid output is smooth.

Description

technical field [0001] The invention relates to the technical field of coffee machines, in particular to a filter assembly and a capsule coffee maker. Background technique [0002] Capsule coffee machine is a kind of coffee machine, which makes the operation of extracting coffee easier and more convenient. When operating the machine, put the coffee capsules into the capsule compartment, and you can extract coffee with one button. Compared with semi-automatic coffee machines and fully automatic coffee machines that use coffee powder, the operation is very simple. For example, the Chinese Patent Publication No. CN103536204A mentions a machine for making coffee with micro-pressure, which includes a brewing chamber and a coffee filter device. The coffee filter device is composed of a brewing filter chamber main body, a filter screen, and a water inlet. The upper cover forms a relatively sealed micro-pressure filter chamber, or the coffee filter device and one end of the brewing...

AI Technical Summary

Problems solved by technology

This solution uses a single filter. If you want to achieve a relatively high pressure and smooth coffee when brewing coffee, you need to open a lot of relatively small holes on the filter. The smaller the aperture, the more difficult it is to inject, so As a result, the pore diameters of the openings on the current filter screen are different, and the production process is difficult; while the larger the pore size, the lower the pressure, and it is impossible to brew coffee with a better taste.
