[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figs. 1-6 A novel coffee grinder includes: a grinding cup 1, with a detachable screen 13 installed inside; a receiving cup 11 threadedly attached to the lower end of the grinding cup 1; a connecting mechanism 4, disposed between the grinding cup 1 and a lid 12, for movably connecting the lid 12 to the grinding cup 1; a fixing mechanism 2, disposed between the grinding cup 1 and the lid 12, for fixing the lid 12 to the grinding cup 1; and a grinding mechanism 3, disposed at the lower end of the lid 12, for grinding the coffee beans inside the grinding cup 1. In this embodiment, the screen 13 is detachably installed inside the grinding cup 1 by bolts and can be removed and replaced.

[0024] The working principle of this utility model is as follows: In specific use, the receiving cup 11 is screwed onto the lower end of the grinding cup 1. Then, coffee beans are added into the grinding cup 1. Next, the cup lid 12 is fixed to the grinding cup 1 by the fixing mechanism 2, which can effectively prevent coffee powder from splashing during grinding. Then, the coffee beans are ground by the grinding mechanism 3. The ground coffee powder is screened by the screening screen 13 and falls into the receiving cup 11 to complete the collection work. The operation is simple and can better meet the needs of use.

[0025] As a further embodiment, the connecting mechanism 4 includes a connecting seat 41 integrally formed on the grinding cup 1. A connecting groove is provided in the connecting seat 41, and a connecting rod 45 is slidably inserted into the connecting groove. The upper end of the connecting rod 45 is fixedly connected to the lower end of the cup lid 12. A connecting limiting groove 42 is also provided on the connecting seat 41. The connecting limiting groove 42 communicates with the connecting groove. A connecting limiting block 43 is slidably installed in the connecting limiting groove 42. The connecting limiting block 43 is fixed to the end of the connecting rod 45. In this embodiment, a locking handwheel 44 is also threadedly inserted into the connecting seat 41. The end of the locking handwheel 44 abuts against the connecting rod 45.

[0026] By setting the connecting limiting groove 42 in conjunction with the connecting limiting block 43, the connecting rod 45 can be prevented from detaching from the connecting seat 41. When coffee beans need to be filled, pull the cup lid 12 up. After the connecting limiting block 43 on the connecting rod 45 abuts against the connecting limiting groove 42, rotate the locking handwheel 44 so that the end of the locking handwheel 44 abuts against the connecting rod 45, thus fixing the cup lid 12 and making it convenient to add coffee beans into the grinding cup 1.

[0027] As a further embodiment, the fixing mechanism 2 includes a fixing seat 21 mounted on the cup lid 12. A fixing guide rod 25 is installed inside the fixing seat 21. A fixing buckle 24 is slidably mounted on the fixing guide rod 25. A fixing spring 26 is also fitted on the fixing guide rod 25. The two ends of the fixing spring 26 are respectively connected to the inner wall of the fixing seat 21 and the corresponding side of the fixing buckle 24. A fixing end cap 22 is also installed on the fixing seat 21. A fixing paddle 23 is slidably mounted on the fixing end cap 22. The fixing paddle 23 is fixedly connected to the upper end of the fixing buckle 24. A fixing frame 27 is installed on the grinding cup 1 at the position corresponding to the fixing buckle 24. The fixing buckle 24 is L-shaped and has a chamfer at its lower end.

[0028] The working principle of the fixing mechanism 2 is as follows: When fixing, push the cup lid 12 down. After the chamfer at the lower end of the fixing buckle 24 contacts the fixing frame 27, continue to push the cup lid 12 down. At this time, the fixing buckle 24 moves to one side of the center of the cup lid 12. At this time, the fixing spring 26 is compressed. After the fixing buckle 24 passes through the fixing frame 27, the fixing spring 26 returns to its original state and pushes the fixing buckle 24 back to its original position. This allows the protrusion at the end of the fixing buckle 24 to fasten to the lower end of the fixing frame 27, thus completing the fixing work. When it is necessary to open the cup lid 12, simply push the fixing lever 23 to move, thereby moving the fixing buckle 24 and separating the fixing buckle 24 from the fixing frame 27, and then pull the cup lid 12 up.

[0029] As a further embodiment, the grinding mechanism 3 includes a grinding rotating shaft 32 rotatably mounted on the lower end of the cup lid 12, a plurality of grinding blades 33 are distributed and mounted on the grinding rotating shaft 32, and a grinding motor 31 is embedded in the cup lid 12, the output end of the grinding motor 31 being drivenly connected to the shaft end of the grinding rotating shaft 32.

[0030] The working principle of the grinding mechanism 3 is as follows: When grinding, the grinding motor 31 is started, which drives the grinding rotating shaft 32 to rotate, thereby driving the grinding blade 33 on the grinding rotating shaft 32 to rotate, thus grinding and crushing the coffee beans.

[0031] As a further solution, a heat dissipation hole is provided on the upper end of the cup lid 12 corresponding to the position of the grinding motor 31.
