[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment, in conjunction with the accompanying drawings, a bean grinder for grinding beans into powder, including a main body 1 and a cup body 2, the main body 1 is provided with a motor 3, a lower cone grinding wheel 4, an upper cone grinding wheel 5, an adjusting wheel 6, a rotating wheel 7 and a decorative ring 8, the lower cone grinding wheel 4 is fixed on the output shaft of the motor 3 and driven to rotate by the motor, the upper cone grinding wheel 5 is arranged at the periphery of the lower cone grinding wheel 4, the gap between the upper cone grinding wheel 5 and the lower cone grinding wheel 4 is a bean grinding gap 9, the bean grinding gap changes between the positions corresponding to the coarse and fine particle sizes of the powder, and the positions corresponding to the coarse and fine particles can be marked on the cup body or the decorative cover for easy viewing. The adjusting wheel 6 is arranged at the periphery of the upper cone grinding wheel 5, and the inner surface of the adjusting wheel 6 is provided with three groups of threads 10 in the same direction at equal intervals, and the corresponding upper cone grinding wheel 5 is provided with three hanging ears 11 at equal intervals around the periphery, each hanging ear is hung on a group of threads, and when the adjusting wheel rotates, the hanging ear rises or falls relative to the threads. The adjusting wheel rotates to drive the upper conical grinding wheel to move up and down, changing the size of the grinding gap. The rotating wheel is linked to the adjusting wheel, and both the rotating wheel and the adjusting wheel can only rotate between positions corresponding to the coarse and fine particle sizes of the powder.

[0027] The cup body 2 includes a container seat 12 arranged at the bottom thereof. When the cup body is installed on the host, the container seat 12 is connected to the rotating wheel 7.

[0028] The connection between the container seat 12 and the rotating wheel 6 includes a connection in the circumferential direction and a vertical connection between the two. The circumferential connection refers to the vertical surface where the outer wall of the container seat 12 and the inner wall of the rotating wheel are in contact with each other, and the convex and concave objects are engaged with each other, so that the two can rotate in a unidirectional manner in the circumferential direction toward the position corresponding to the coarse or fine particle size of the powder. The convex and concave objects refer to the L-shaped ribs 13 provided on the outer surface of the container seat 12, and the grooves 14 are formed inside the L-shaped ribs. The inner surface of the rotating wheel 6 is provided with a straight-line protrusion 15, and the protrusion 15 is screwed into the groove 14 to realize the engagement between the container seat and the rotating wheel. If there is no vertical connection structure below after the convex and concave objects between the container seat and the rotating wheel are engaged, the container seat can only drive the rotating wheel to move in one direction, that is, it can only rotate in a unidirectional manner toward the position corresponding to the coarse or fine particle size of the powder.

[0029] The vertical connection refers to an elastic connector between the bottom surface of the container seat 12 and the top surface of the rotating wheel 6. The elastic connector refers to an elastic column 16 installed on the container seat 12. The elastic column structure itself is a prior art and will not be described in detail. The drawing shall prevail. A countersunk hole 17 is provided on the surface of the rotating wheel 6. When the elastic column is screwed to the top of the countersunk hole, it is inserted into the countersunk hole to realize the linkage between the container seat and the rotating wheel. In particular, when the container seat rotates in the opposite direction relative to the above-mentioned unidirectional rotation direction, the elastic column can realize the container seat driving the rotating wheel to rotate. When the rotating wheel rotates in the opposite direction and cannot move, the container seat continues to be applied with a force in the same direction. The elastic column detaches from the countersunk hole to separate the container seat and the rotating wheel, and the cup body is separated from the main machine. Here, the depth of the elastic column inserted into the countersunk hole needs to satisfy the requirement that the container seat is subjected to a certain amount of force, and the elastic column can slide out of the countersunk hole.

[0030] The bottom surface of the container seat 12 is provided with a bean outlet hole 18, which is closed and opened by two doors 19. Two columns 20 are provided on the surface of the rotating wheel 6. When the container seat is installed on the main machine, the two columns are respectively inserted into the opening grooves 21 of the two doors 19. During the process of locking the container seat and the rotating wheel in the circumferential direction, after the two columns open the two doors, the elastic column vertically connects the container seat and the rotating wheel at the same time.

[0031] The decorative ring 8 is fixed to the top port of the main machine. When the container seat is installed on the main machine, the decorative ring surrounds the container seat.
