[0002] A coffee bean grinder is a device used to grind coffee beans into coffee powder. During the grinding process, coffee beans are easily retained and adhered to coffee powder around the grinding discs for the upper and lower grinding discs. For example, the patent document with application number CN202020717934.8 discloses a two-stage adjustment structure for the gap between the blade discs of a coffee bean grinder. The fine adjustment knob is used to rotate the threaded sleeve alone to achieve fine adjustment so that the distance between the blade discs can be infinitely adjusted, making the coarseness of the ground powder more finely divided.
[0003] However, in the above-mentioned similar schemes, during use, beans or bean powder roll down from the bean grinding bin into the shell, thereby preventing beans from being scattered into the gap between the shell and the grinding disc for a long time, causing deterioration and odor. In addition, the existing device adjusts the distance between the positioning device and the grinding head by rotation, and the thread becomes wider after long-term friction, resulting in a decrease in accuracy during callback.

[0018] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.
[0019] like Figures 1 to 3As shown, an adjustable grinding disc positioning device includes a grinding disc 1, an adjusting ring 2, an upper sealing cover 3, and a lower sealing cover 4. The adjusting ring 2 is rotatably connected to the grinding disc 1, and the grinding disc 1 is screwed into the adjusting ring 2. The adjusting ring 2 drives the grinding disc 1 to move up and down, thereby forming an adjustable grinding coarseness of the grinder. The upper sealing cover 3 covers the connection between the grinding disc 1 and the adjusting ring 2, and the lower sealing cover 4 covers the connection between the grinding disc 1 and the adjusting ring 2. The grinding disc 1, the upper sealing cover 3, and the lower sealing cover 4 are detachably connected.
[0020] The device combines the grinding disc 1 and the adjusting ring 2 to form a separate product component, which is convenient for users to remove and clean, and reduce the residual bean powder from breeding mold, etc. The upper sealing cover 3 is used to prevent beans from entering the device, and the lower sealing cover 4 prevents bean powder from entering the device.
[0021] In the present technical solution, a detachable connection method between the grinding disc 1 and the upper sealing cover 3 and the lower sealing cover 4 is exemplified. A fixed slot 101 is provided on the grinding disc 1, and a fixed protrusion 401 is provided on the lower sealing cover 4. The fixed protrusion 401 passes through the fixed slot 101 and is detachably connected to the upper sealing cover 3.
