In order to achieve the above object, the technical means adopted by the present invention is to provide a grinding device comprising an outer grinding ring and an inner grinding seat, wherein the outer grinding ring is an annular sleeve body, and the upper wall of the inner wall is continuously concavely provided with coarse grinding. a tooth, the lower part of the inner wall is provided with fine grinding teeth, and the inner grinding seat is disposed inside the outer grinding ring and maintains a gap. And rotating by the rotating shaft, the inner grinding seat has a conical shape, the ring surface of the cone has a plurality of concave grooves, and the lower ring is provided with a plurality of fine grinding teeth, and the plurality of concave grooves extend from the tapered surface to the tapered surface to The fine grinding tooth is set to have a concave inclination shape; wherein the plurality of concave grooves have a surface and a guiding surface, wherein the cutting surface is vertically formed by the inner grinding seat top facing downward, and the cutting surface is tapered A straight-shaped cutting edge is provided obliquely downward along the tapered surface, so that the top surface of the inner grinding seat forms a polygonal shape, and the guiding surface extends from the cutting edge of the cutting surface downward to the fine grinding tooth portion to be in an inclined plane shape.

A further technical feature of the present invention is that the cut surface is inclined from the top of the inner grinding seat to the vertical or from the top to the bottom.

A further technical feature of the present invention is that the top surface of the inner grinding seat is in the form of an equilateral polygon.

The main advantage of this creation is that the cut surface of the groove of the creation is set vertically or downwardly from the top to the bottom of the inner grinding seat, so that the inner grinding seat is lowered and the coarse grinding tooth of the outer grinding ring is broken. The strength of the coffee beans prevents seizure of the grinding device and prevents the motor from being burnt due to excessive load.
