Bean bin with protective switch

By using the connection tube at the bottom of the coffee bean hopper in conjunction with the safety switch inside the machine mounting base, a physical power-off protection is achieved through the mechanical structure of a spring and a return needle. This solves the safety hazard problem of children caused by accidental operation after the coffee bean hopper is disassembled, thus improving safety.

AI Technical Summary

Technical Problem

Even after the bean hopper of an existing coffee machine is disassembled, the grinding disc can still be started manually via a button. This exposes high-speed rotating parts, posing a safety hazard to children, especially in case of accidental operation, which could result in blade injuries.

Method used

Design a bean hopper with a protective switch. By cooperating with the safety switch in the mounting base of the machine body through the connecting cylinder at the bottom of the bean hopper, a physical power-off protection is achieved by using the mechanical structure of spring and return needle. This ensures that the circuit is connected when the bean hopper is fully screwed in and automatically cuts off the power when it is screwed out, thus avoiding accidental operation.

Benefits of technology

It achieves enhanced safety without complex modifications, completely eliminating the risk of knife injuries caused by children's accidental operation and ensuring high safety.
