Abstract

The invention provides a coffee bean grinder, which is simple in structure, is detachable and has few residues. The coffee bean grinder comprises a machine body, a grinding cavity and a coffee powder grinding device, wherein the grinding cavity is arranged on the machine body; the coffee powder grinding device is arranged in the grinding cavity; the coffee power grinding device comprises an outer grinding component arranged on the upper part of the coffee power grinding device and an inner grinding component arranged on the lower part of the coffee power grinding device; a through hole through which coffee powder directly flows out is formed at the bottom of the grinding cavity; an adjusting gear sleeve is sleeved on the outer wall of the grinding cavity; screw threads are formed on the inner wall of the adjusting gear sleeve; and a clamping buckle meshed with the screw threads on the inner wall of the adjusting gear sleeve is arranged on the upper part of the outer grinding component. In a rotation process of the adjusting gear sleeve, the outer grinding component moves up and down along the outer grinding component and is separated from or screwed into the screw threads of the adjusting gear sleeve. The detachable outer grinding component is adopted in the coffee bean grinder, so the cleanliness of internal components of a product is improved. At the same time, the coffee bean grinder is simple in structure and small in occupied space, so the manufacturing cost is obviously reduced.
