The grinding disc assembly has a powder outlet at the bottom for discharging the bean powder, and the powder hopper is located below the powder outlet to collect the powder. When the grinding disc is grinding beans, static electricity is often generated due to the friction between the grinding disc and the beans. This causes powder to fly out and some powder to be attracted to the powder outlet during the powder collection process, affecting the powder collection and resulting in a poor user experience. In addition, some existing grinding disc assemblies are not detachable or are inconvenient to disassemble, which makes cleaning inconvenient. Utility Model Content
