Referring to Figures 2, 3, and 4, before the grinding device of the present invention grinds, the pills 91 to be ground are put into the accommodating space 10, and then the driving unit 3, the grinding unit 2 and the covering unit are assembled. 4. Finally, the ring wall 44 of the cover unit 4 is screwed to the surrounding wall 16 of the base body 11 to complete the assembly. At this time, since the pills 91 located between the sieve 14 and the bottom of the grinding column 21 are relatively large, the grinding column 21 will be pushed upward by the pills 91 , thereby compressing the second elastic member 47 .

When the grinding device of the present invention starts grinding, press the pressing cap 332 of the pressing module 33 downward, and the driving member 35 of the driving mechanism 32 will drive the driving module 36 to drive the grinding unit 2 to rotate. During the continuous rotation of the grinding unit 2 , the particles of the pills 91 will be ground smaller and smaller, and the grinding unit 2 will move downward. At the same time, the elastic force generated by the second elastic member 47 will push the moving member 42 downward, and then push the grinding column 21 against the pills 91, which is beneficial to improve the grinding efficiency.

When the grinding is finished, as long as the pressing cap 332 is loosened, the pressing module 33 will be bounced upward by the elastic force produced by the first elastic module 34, and the pressing module 33 will drive the driving mechanism 32 Move up to return to the state before grinding. It is worth mentioning that, due to the mechanical characteristics of the one-way bearing 361 of the driving and rotating module 36, when the driving and rotating mechanism 32 moves upwards, the one-way bearing 361 will not drive the grinding unit 2 to drive backwards. change.

To sum up, through the design that the driving unit 3 can be driven to rotate the grinding unit 2, it can replace the traditional grinding method, and has the advantages of saving labor and improving grinding efficiency. Furthermore, the covering unit 4 includes a structural design in which the moving part 42 cooperates with the second elastic module 43, the grinding column 21 is pushed by the moving part 42 and leans against the pills 91 downwards, It is beneficial to improve the grinding efficiency. In addition, the design of the upward elastic force that can be generated by the first elastic module 34, after the pressing cap 332 is released, the pressing module 33 will automatically spring upwards, which is very convenient and is a very innovative and practical creation. Therefore, the object of the present invention can be achieved indeed.

But the above-mentioned ones are only embodiments of the present invention, and should not limit the scope of the present invention.
