Knob structure of small household appliance, steamer and hot water kettle

By adopting a knob structure in small household appliances, the temperature control switch is turned on and off by using a transmission rod and elastic arm to drive the rocker plate to rotate. This solves the problem of aging of push-button switches and achieves low-precision machining and stable knob operation.

AI Technical Summary

Technical Problem

The existing push-button switch structure of small household appliances is prone to aging after a period of use, which leads to high requirements for processing precision and affects the performance. The rotary switch requires a major modification to the conventional push-button switch.

Method used

The system employs a knob structure, which directly or indirectly drives the rocker to rotate. Combined with the transmission rod and elastic arm, it enables the temperature control switch to be opened and closed, avoiding significant modifications to conventional rocker switches and reducing the requirements for machining accuracy.

Benefits of technology

It achieves the stability and low machining precision requirements of a purely mechanical knob structure, avoids modifications to conventional rocker switches, and improves usability.
