[0030] The ceramic heater 8 described in this embodiment is a hollow cylindrical structure with several heating air vents. These vents are hexagonal and honeycomb-shaped, preventing gaps and saving costs. The ceramic heater 8 uniformly heats the airflow. It can be electrically connected to the battery pack 2 via electrodes installed in corresponding grooves. The ceramic heater 8 is fixed to the air outlet duct 15 by a mica bracket 12. The air outlet duct 15 has a mica slot 14 for fixing the mica bracket 12. This invention uses the mica bracket 12 to prevent heat conduction and to fix the ceramic heater 8 in the correct position, preventing slippage.
