[0001] The present invention relates to the technical field of electric heaters, and in particular to a front shell device and an electric heater. Background Art

[0002] Oil heaters, a type of electric heater with good heating effect and convenient heating, are now increasingly used. Since electric heaters are mainly used in cold winter and mainly at night in winter, in order to avoid users getting up at night to operate the electric heater, electric heaters with offline voice control functions are becoming more and more popular in the market. Voice control functions are usually implemented by components such as speakers and microphones.

[0003] However, since voice control components such as speakers and microphones are electrical parts, the heat emitted by the electric heater may affect the voice control components. Summary of the invention

[0004] In view of this, the present invention provides a front housing device and an electric heater to solve the problem that the heat emitted by the electric heater affects the voice control component.
