[0034] The working principle and usage process of this utility model are as follows: This device mainly includes a grinding device 1, a collecting cylinder 2, an electric grinding mechanism, and a manual grinding mechanism. The grinding device 1 is located at the core of the device, and a collecting cylinder 2 is installed at its bottom to collect the powder or particles generated during grinding. The electric grinding mechanism is connected to the top of the grinding device 1 via a diamond-shaped connecting block 3. A locking block 4 is fitted on the surface of the diamond-shaped connecting block 3, and a transmission gear 5 is fixed on the top of the locking block 4. This gear meshes with a drive gear 6, and a motor 7 is connected to the top of the drive gear 6. A housing 8 is fixed to the top of the motor 7, and the bottom of the housing 8 extends into the interior of the grinding device 1 and is threadedly connected to it to ensure stability. A diamond-shaped extension block 9 is also fixed to the top of the transmission gear 5. This extension block is movably connected to the inner wall of the housing 8 via a bearing to achieve smooth rotation. When the motor 7 starts, it drives the transmission gear 5 to rotate through the drive gear 6, which in turn drives the locking block 4 and the diamond-shaped connecting block 3 to rotate. The diamond-shaped connecting block 3 then links the grinding device 1 to perform the grinding work. The powder or particles generated during grinding fall into the collecting cylinder 2. In addition, a manual grinding mechanism is provided on the top of the housing 8. The connecting rod 11 and the diamond-shaped extension block 9 can be rotated by operating the handle 13 to achieve manual grinding. Alternatively, the automatic grinding mechanism can be unscrewed, and the manual grinding mechanism can be directly installed on the top of the grinding device 1 for use. After grinding, the top of the connecting piece 15 can be inserted into the locking block 4, and the washing rod 16 can be rotated by the motor 7, thereby extending the washing rod 16 into the collection cylinder 2 or the interior of the grinding device 1 for cleaning. This avoids the inconvenience caused by the limited functionality of existing manual grinders, giving it the advantage of ease of use.

[0035] In summary, when this utility model is used, under the action of the automatic grinding mechanism, the manual grinding mechanism and the cleaning component, the grinder can simultaneously have the functions of automatic and manual grinding. Furthermore, the cleaning component can facilitate the cleaning of the grinding device 1 and the collection cylinder 2, avoiding the inconvenience caused by the single function of the existing manual grinder, thus giving it the advantage of ease of use and solving the problem of its single function.
