Interchangeable grinding cartridge device

Abstract

An automatic grinder and a grinding method thereof. The grinder includes a control structure and at least one material container assembly. The control structure includes a driving assembly and a connecting structure connected to the driving assembly. The material container assembly includes a material container body (), a grinding head () fixedly connected to the material container body (), and a grinding sleeve () rotatably connected to the grinding head (). A recess () is provided on the material container body (), and the connecting structure is engaged with the recess (). The grinding head () is fitted into the grinding sleeve (), and the grinding head () and the grinding sleeve () define therebetween a material compartment () for accommodating a material. The driving assembly drives, via the connecting structure, the material container body () to rotate. The material container body () drives the grinding head () to rotate. The grinding head () moves relative to the grinding sleeve (), such that the material between the grinding head () and the grinding sleeve () is ground into powder. The automated grinder is provided with different grinding sleeves and grinding heads for grinding a variety of materials, and prevents the introduction of impurities during feeding, thereby preserving the original flavor of the material.
