That is to say, in prior art, when good gear is selected, no matter the user is far away from the electric heater or the ambient temperature is high or low, wind speed and heating power are all fixed, can not switch according to user's demand intelligence all. Moreover, when the wind power of the electric heater is too strong, the noise will be large, the rest of the user is influenced, the comfort of the user is greatly influenced, the requirement of the user cannot be met, and the waste of electric energy can be caused.

In other embodiments of this disclosure, the electric heater in this disclosure can satisfy the requirement of user's comfort level according to people and electric heater's distance and ambient temperature and intelligent adjustment wind speed, energy-concerving and environment-protective.

It can be understood that the electric heater in the present disclosure further includes a distance detector for detecting a distance between a user and the electric heater.
