[0022] As shown in Figure 1 and Figure 2 A detachable grinding mechanism for a coffee grinder comprises an upper grinding structure 100 and a lower grinding structure 200 that grind together, and a connecting box 6 is arranged outside the joint of the upper grinding structure 100 and the lower grinding structure 200. The connecting box 6 is fixed inside the coffee grinder body, the upper grinding structure 100 is detachably connected to the upper part of the connecting box 6, the bottom of the lower grinding structure 200 is connected to a driving device 5 through a coupling device, and the driving device 5 is fixed inside the coffee grinder body.

[0023] It should be noted that in the embodiment, the upper grinding structure 100 is detachably connected to the connecting box 6, and the user can detach and remove the upper grinding structure 100 after use, so that the user can clean the residual coffee powder between the upper grinding structure 100 and the lower grinding structure 200 at any time, and the residual coffee powder is prevented from blocking the channel. In addition, the coffee grinder can conveniently clean the residual coffee powder inside, and food hygiene and safety problems caused by the deterioration of the residual coffee powder can be avoided. The lower grinding structure 200 is connected to the driving device 5 in the coffee grinder through the coupling device, so that the driving device 5 can drive the lower grinding structure 200 to rotate through the coupling device. The middle part of the upper grinding structure 100 and the lower grinding structure 200 is hollow, which is convenient for placing coffee beans. The coffee beans can be transferred between the upper grinding structure 100 and the lower grinding structure 200 under the action of centrifugal force, and are ground into coffee powder by the interaction of the upper grinding structure 100 and the lower grinding structure 200, and are guided out of the connecting box 6.
