A food processor with magnetic micro-switch and locking structure

Through a magnetic micro-switch and locking structure, the food processor triggers the circuit to connect when the top cover is correctly assembled with the body and cuts off the power when separated, thus solving the safety hazard problem of the food processor and ensuring operational safety and stable power supply.

AI Technical Summary

Technical Problem

Existing food processors may start accidentally if the lid and cup are not properly assembled, posing a safety hazard of exposed high-speed blades or high-temperature components. Furthermore, forcibly opening the lid during operation may cause food to splatter or cause burns.

Method used

Employing a magnetic micro-switch and locking structure, the circuit is activated when the top cover and body are correctly assembled using magnetic components with repulsive polarities, and automatically de-energized when separated. A secure locking connection is formed through the interlocking of the protrusions and recesses, ensuring that the top cover and body are powered on only when correctly connected.

Benefits of technology

This ensures that the food processor is powered on only after it is correctly assembled, preventing accidental start-up and separation, guaranteeing operational safety and stable power supply, and eliminating risks such as mechanical impact and high-temperature liquid splashing.
