[0002] The electric blast drying oven is a commonly used instrument in laboratories. It is mainly used to dry samples or provide the temperature environment required for the experiment. The working principle of the electric blast drying oven is to generate hot air through electric heating and blow out the hot air through a circulating fan to ensure the temperature balance in the box.

[0003] However, the drying boxes currently on the market generally use a blower to blow in air that is heated by a heating net and then flows into a drying chamber, while the positions of the drying element and the air outlet are relatively fixed.
