[0002] Coffee, as one of the world's three major beverages, is a well-known drink with a long history and is increasingly accepted by consumers. To enjoy freshly brewed coffee, equipment such as coffee grinders is indispensable. Coffee grinders play a crucial role in coffee making, primarily grinding coffee beans through their grinding components. Generally, they utilize flat or conical burr grinding discs, where the relative rotation of two discs compresses and shears the coffee beans between the discs, grinding them into powder.

[0003] However, the current coffee grinders use either electronic touch controls or push-button switches. Push-button switches typically only have simple on / off functions, resulting in a mediocre user experience, and therefore require further optimization and improvement. Utility Model Content
