AI Technical Summary
Existing microwave ovens, steam ovens, and microwave ovens lack interlocking mechanisms, resulting in the doors not being able to effectively lock and unlock when opening and closing.
Design an interlocking lever structure. Through the cooperation of the lever and the base frame, the rotation of the lever triggers the linkage switch, and the return spring realizes the reset of the lever, ensuring that only one linkage switch is touched.
It enables effective linkage between the door and different opening/closing positions, improving the product's ease of use and safety.
