Regulating device for regulating fineness of ground coffee and coffee grinder

Abstract

The invention discloses a regulating device for regulating the fineness of ground coffee and a coffee grinder. The regulating device comprises a first bracket which is arranged under a motor and fixed at the lower end part of the motor, a regulating element and a limiting auxiliary regulating structure, wherein an axial screw hole is formed in the middle of the first bracket, and the upper tail end of the motor rotating shaft of the motor is fixedly connected with a lower millstone which is matched with an upper millstone so as to grind the coffee; the regulating element is screwed in the axial screw hole of the first bracket, and the lower tail end of the regulating element is provided with a polygonal regulating screw head; the limiting auxiliary regulating structure is used for preventing the regulating element from being loosened in the axial screw hole of the first bracket and providing the regulating element with rotation so as to regulate the axial position of the lower millstone; the limiting auxiliary regulating structure is connected with the regulating screw head. The regulating device can decrease the difficulty of manufacturing and improve the quality and efficiency of production, and is convenient to operate and high in reliability.

Description

technical field [0001] The invention relates to a grinding device, in particular to an adjusting device for adjusting the grinding thickness of coffee and a coffee grinder. Background technique [0002] In order to meet people's habit of consuming coffee, a coffee grinder has appeared to provide users with the convenience of grinding coffee powder at any time. However, most of the coffee grinders can only grind coffee powder of the same thickness basically on the same machine, and it is difficult to adjust conveniently according to different requirements of different people for the thickness of coffee powder. [0003] Chinese patent application CN2010206119100 proposes a coffee grinder capable of adjusting the thickness of coffee powder. During operation, the distance between the upper and lower grinding discs must be adjusted. The upper grinding disc positioning seat is rotated by the adjusting ring and screwed into the threaded ring seat. The distance between the two grin...
