[0029] Embodiment 1:

[0030] Figure 1-Figure 4 The utility model shows a portable coffee grinder with adjustable gear position, comprising a shell 1, a grinding disc 2, a grinding core 3, an adjusting ring 4, and an adjusting piece 5. The grinding disc 2, the grinding core 3, and the adjusting piece 5 are arranged in the shell 1, the adjusting ring 4 is rotatably connected to the shell 1 and the outer edge is flush with the shell 1, the adjusting piece 5 is threadedly connected to the middle part of the adjusting ring 4, the inner edge of the shell 1 is provided with a guide groove 11, the outer edge of the adjusting piece 5 extends outward to form a guide column 51, the guide column 51 cooperates with the guide groove 11 to limit the adjusting piece 5 to only move up and down, the grinding disc 2 is fixed in the shell 1 and a grinding cavity is provided in the middle part, the grinding core 3 is arranged in the grinding cavity, the lower end of the grinding core 3 abuts against the adjusting piece 5, and the grinding core 3 is lifted and moved when the adjusting piece 5 moves up and down. The grinding core 3 and the grinding disc 2 have mutually matched inclined surfaces to form a grinding gap. When the grinding core 3 moves upward, the grinding gap becomes smaller and the ground coffee powder particles become smaller. Conversely, when the grinding core 3 moves downward, the ground coffee powder particles become larger.

[0031] A motor 12 and a rotating rod 13 are arranged in the housing 1. The rotating rod 13 is connected to the output end of the motor 12. The motor 12 can control the rotating rod 13 to rotate. The rotating rod 13 is fixedly connected to the grinding core 3, so that the grinding core 3 and the rotating rod 13 can rotate synchronously to realize the function of grinding beans.

[0032] A side edge is provided on the rotating rod 13 , and a spring 7 is provided between the side edge and the grinding core 3 , and the spring 7 applies a downward elastic force to the grinding core 3 .

[0033] A bracket 6 is arranged between the adjusting member 5 and the grinding core 3. The upper end of the bracket 6 is engaged with the lower end of the grinding core 3 through three blocks and rotates with the grinding core 3. The outer edge of the bracket 6 extends downward to form a convex edge 61, and the bracket 6 is buckled on the adjusting member 5 through the convex edge 61.

[0034] There are provided guide grooves 11 and guide posts 51 which cooperate with each other. The guide posts 51 and the guide posts 51 are directly hollowed out to allow coffee powder to fall. There are at least three groups of guide posts 51 and guide grooves 11. In this embodiment, the minimum number of guide posts 51 and guide grooves 11 is set, that is, three groups.

[0035] The lower end of the adjustment ring 4 is detachably connected to a powder cup 8, and the powder cup 8 is used to hold the coffee powder dropped from the grinding core 3. The powder cup 8 and the adjustment ring 4 are connected to each other through a damping structure. The user grasps the powder cup 8 and applies a downward pulling force to the powder cup 8, and the powder cup 8 can be pulled out to separate it from the adjustment ring 4 and the outer shell 1. The upper edge of the powder cup 8 can be buckled into the adjustment ring 4 by applying a reverse force.

[0036] The shell 1 is provided with a coarseness scale 9 near the adjustment ring 4, and the coarseness scale 9 corresponds to the rotation direction of the adjustment ring 4. The user can observe the scale indicator 41 provided on the adjustment ring 4 according to his own needs, and freely rotate the adjustment ring 4 to make the scale indicator 41 rotate to the specified scale position to obtain coffee powder of corresponding coarseness.

[0037] The outer edge of the adjusting ring 4 also has an anti-slip structure, which makes it easy to apply force and facilitates the user to rotate the adjusting ring 4.

[0038] Since the adjustment ring 4 is arranged on the outside, the user can also rotate it when the grinder is started. In this way, the adjustment ring 4 can be repeatedly rotated during one grinding process. The final coffee powder has layers, and each layer has a different coarseness and fineness, which can meet the special needs of some users for coffee powder.

[0039] Working principle:

[0040] The top of the shell 1 can be opened and the coffee beans to be ground can be put in. After the coffee beans are put in, they are stacked on the grinding disc 2 and the grinding core 3. The grinding gap between the grinding disc 2 and the grinding core 3 is always smaller than the unground coffee beans. Then, according to the demand for coarseness, the adjusting circle 4 is rotated to the specified position. The adjusting circle 4 drives the adjusting part 5 to lift the grinding core 3 to overcome the elastic force of the spring 7 and rise. The gap between the grinding core 3 and the grinding disc 2 is reduced. When the adjusting circle 4 is rotated in the opposite direction, the gap between the grinding core 3 and the grinding disc 2 can be increased. After setting the coarseness, press the start button on the top, and the motor 12 drives the rotating rod 13 to drive the grinding core 3 to rotate to grind the coffee beans. The ground coffee powder falls down and is stored in the powder cup 8.
