Description

[Technical field]

[0002] In the existing electric iron design, the handle button is an important control element of the electric iron, and its functionality and ease of use have a vital impact on the user experience. The traditional electric iron handle button has a simple structure, and is generally used in conjunction with a conductive glue button to realize the on-off control of the circuit. After being pressed, this traditional electric iron handle button completely relies on the elasticity of the conductive glue to achieve rebound and reset. As an elastic material, the material properties of the conductive glue will gradually decrease during long-term use, resulting in elastic failure. Once the elasticity of the conductive glue button fails, the handle button will not be able to rebound and reset smoothly after being pressed, so that the electric iron remains in a working state when powered on, which will not only affect the normal use of the electric iron, but more importantly, it will bring great safety hazards to users. Therefore, there is an urgent need for a handle button for an electric iron with an auxiliary rebound structure. [Summary of the invention]
