AI Technical Summary

Technical Problem

In existing coffee machine conical burr structures, coffee powder tends to accumulate in the gap between the annular fixed burr and the conical moving burr, preventing it from falling off and resulting in waste.

Method used

A striking component is incorporated into the conical grinding disc structure of the coffee machine, comprising an inner and outer annular discs. A control shaft drives the conical moving blade to rotate and grind coffee beans, while a cleaning ball on the inner annular disc strikes the fixed annular blade, reducing powder buildup.

Benefits of technology

This effectively reduces the accumulation of coffee powder in the gap between the annular fixed cutter head and the conical moving cutter head, improving the utilization rate of coffee powder and avoiding waste.

Abstract

This utility model discloses a conical grinding disc structure for a coffee machine, relating to the field of conical grinding disc technology for coffee machines. It has the advantage of reducing the possibility of coffee powder accumulating in the gap between the annular fixed blade and the conical moving blade, thus preventing it from falling into the powder container and causing waste. The key technical points are: a grinding chamber with a hollow inner cavity, an open bottom, and a connecting groove penetrating the middle of the top, communicating with the outside. An annular tray is fixed to the top of the groove outside the connecting groove. An annular fixed blade is detachably and fixedly connected to the annular tray. A conical moving blade adapted to the annular fixed blade is provided inside the annular fixed blade. The bottom end of the conical moving blade extends out of the annular fixed blade. A control shaft is fixed in the middle of the conical moving blade, with both ends of the control shaft extending out of the conical moving blade. A striking component is provided inside the grinding chamber, fitted outside the annular fixed blade.
