Description

Technical Field

[0001] The present invention relates to the technical field of coffee bean grinders, and in particular to a powder discharging structure of a coffee bean grinder. Background Art

[0002] A coffee grinder is a specialized device used to grind coffee beans into powders of varying coarseness and fineness, and is widely used in coffee-making scenarios. Its core function is to mechanically break down whole coffee beans and process them into a powder that meets brewing requirements. Different grind sizes correspond to different coffee-making methods (e.g., espresso requires ultra-fine powder, pour-over coffee requires medium-coarse powder), directly affecting the extraction efficiency and flavor of the coffee. The grinding effect of a coffee grinder depends on its grinding precision (the uniformity of the powder particles) and adjustability (the ability to precisely control the coarseness), making it a key piece of equipment in determining coffee quality.

[0003] The basic structure of a coffee bean grinder is mainly composed of five core parts: one is the feeding device (such as a hopper), which is used to store the coffee beans to be ground; the second is the grinding assembly, which is the core working part, usually composed of a pair of grinding discs (flat blades, conical blades, etc.) or grinding cores, which cut and crush the coffee beans through relative rotation; the third is the adjustment mechanism, which is used to control the spacing between the grinding discs, thereby adjusting the coarseness of the ground powder; the fourth is the power system (motor), which provides driving force for the grinding assembly; the fifth is the discharge device (such as a powder bin, powder outlet), which collects the ground coffee powder.

[0004] However, existing grinders still have significant limitations in practical use: when ground coffee powder is discharged from the discharge device to the powder outlet, due to its light texture and easy absorption, it easily accumulates and clumps on the inner wall of the powder outlet, resulting in poor discharge. In this case, the operator must frequently tap the powder outlet to facilitate the discharge of the powder, which not only increases the operation steps but also may affect the stability of the equipment due to improper tapping force. Overall practicality needs to be improved.

[0005] For example, the prior art with patent number CN202422053179.9 and titled as a coffee bean grinder also has the above-mentioned problems. Summary of the Invention
