AI Technical Summary
Technical Problem
In existing coffee brewing systems, the coffee cake is of uneven thickness, which affects the quality of the coffee.
Method used
It adopts a cone-shaped convex coffee pouch structure that is thicker in the middle and thinner around the edges. By setting filter plates on the brewing head assembly and the coffee pusher assembly, a cone-shaped convex coffee pouch is formed, which ensures that hot water passes through the middle area of the coffee pouch for extraction first.
Benefits of technology
It improves the extraction rate and quality of coffee, enhances the uniformity of coffee cake thickness, and improves coffee quality.

Abstract
This invention provides a coffee brewing system and a coffee machine, belonging to the field of coffee machine technology. The coffee brewing system includes a machine body and a brewing head assembly, a brewing chamber assembly, and a coffee pusher assembly mounted on the machine body. The free ends of the brewing head assembly and the coffee pusher assembly can approach each other and compress the coffee powder falling into the brewing chamber to form a coffee cake. The coffee brewing system also includes a first filter and a second filter. One of the first and second filter is located at the free end of the brewing head assembly, and the other is located at the free end of the coffee pusher assembly. The first and second filter are opposite each other. The second filter has a filter cavity formed by a recess in the direction away from the first filter, and the inner diameter of the filter cavity gradually decreases in the direction away from the first filter. One of the free ends of the brewing head assembly and the coffee pusher assembly is the liquid outlet, and the other is the liquid inlet. The coffee cake extruded by this brewing chamber is a cone-shaped convex cake with a thicker center and relatively thinner edges, improving the quality of the coffee.
