Background Art
[0002] An electric heater is a common electric heating device. It generates heat through built-in electric heating elements and blows out hot air through a single air outlet to heat the indoor space. However, single-sided air outlet may lead to uneven heat distribution, with a higher temperature in the area close to the heater and a relatively lower temperature in the area far from the heater, because the heat dissipation is limited to a single air outlet. The heating speed of the single-sided air outlet electric heater may be slower. In addition, the existing electric heaters generally only heat the air and do not have the function of purifying the air. To improve the practicability of the electric heater and increase its functions, we propose a new technical solution.
