Problems solved by technology

[0002] Electric heaters are one of the important equipment in daily life. Traditionally, stainless steel electric heating tubes are generally used. The structure is to put electric heating wires in the metal tubes, and the gaps are tightly filled with thermally conductive and insulating magnesium oxide powder. The advantage is that the stainless steel electric heating tube is a purely resistive load, and the power is easy to determine. The disadvantage is that it can only be controlled on and off, and the power cannot be automatically adjusted according to the temperature.
At the same time, when dry burning occurs due to accidents, it is easy to cause the heating temperature of the stainless steel electric heating tube to be uncontrollable, causing great safety hazards and easily causing explosions, fires and other injuries.

Abstract

The invention relates to an air heating device. The air heating device comprises a rectangular shell, a forced air circulation device and a power source, wherein both the left end and the right end of the rectangular shell are provided with openings. A plurality of PTC heating pieces are arranged in the shell. The power source is arranged at the bottom of the rectangular shell to supply power to the PTC heating pieces and the forced air circulation device. The forced air circulation device rotates anticlockwise. The opening in the left end of the rectangular shell is an air inlet. The opening in the right end of the rectangular shell is an air outlet. By means of the air heating device, the loss of heat energy is reduced effectively, so that heating efficiency is improved remarkably, and risks of safety accidents such as explosion and fire can be reduced to a great extent.
