[0002] Existing coffee machines generally include a bean box and a grinding box assembly arranged up and down. A large amount of coffee beans are stored in the bean box, and the bean output of the bean box is controlled according to the weight of the beans to be ground, so as to input a specific amount of coffee beans into the grinding box assembly.

[0003] For example, a Chinese invention application with publication number CN115721184A provides a grinding system, including a bean bin assembly, a bean lowering assembly, a bean grinding assembly, a weighing assembly and a controller, wherein the bean bin assembly is connected to the bean lowering assembly, the weighing assembly is located between the bean lowering assembly and the bean grinding assembly, and both the bean grinding assembly and the bean lowering assembly are connected to the controller; the controller receives the weight of the object to be ground, and controls the operation of the bean lowering assembly according to the grinding coefficient and the weight to be ground corresponding to the object to be ground, so as to deliver the object to be ground of the weight to be ground to the bean grinding assembly; the bean grinding assembly grinds the object to be ground of the weight to be ground. Since the defective beans caused by the roasting of coffee beans themselves have a great influence on the flavor of boutique coffee, users need to weigh them first and then pick out the defective beans when brewing coffee accurately. Coffee beans may also deteriorate if stored in the bean bin assembly for a long time, so it is necessary to monitor the quality of the coffee beans after weighing and before grinding. When the above-mentioned grinding system is in use, the user will pour a large amount of coffee beans into the bean bin assembly. The coffee beans in the bean bin assembly will directly fall into the bean grinding assembly for grinding after passing through the bean lowering assembly and the weighing assembly. The quality of the coffee beans cannot be monitored after weighing and before grinding.

[0004] Therefore, the prior art has a large room for improvement. Utility Model Content
