Description

The present invention relates to a crusher, and more particularly to a crusher with a quick-detachable crushing base.

A crusher according to the prior art is a device for crushing a material to be crushed (e.g., coffee beans) into granules, and the crushing mechanism of the crusher mainly comprises a crusher and a crusher head located inside the crusher, The grinding head is driven to rotate by a drive mechanism. The crushing disc is non-rotatable, and an externally input object to be crushed is put between the crushing disc and the crushing head. When the crushing head rotates, the crushing teeth inside the crushing disc and the crushing teeth outside the crushing head rotate relatively, and the material to be crushed is crushed into granules.

However, in the conventional crusher technology mentioned above, a very precise structure is used to attach the crushing head inside the crusher, so that the crushing head and the crushing disc are precisely aligned and the purpose of crushing is uniform. have achieved. In addition, such a crushing mechanism has a very complicated overall structure, and it takes a long time to correct it at the time of manufacture. In addition, when the user cleans the crusher, it is difficult to remove the crushing head, and it often takes a long time to attach and detach, which is very inconvenient. Moreover, such a structure has the problem that the cost is very high.

Therefore, the inventor of the present invention thought that the above-mentioned drawbacks could be improved, and as a result of earnest studies, he came to the proposal of the present invention to effectively improve the above-mentioned problems with a rational design.
