The electric air blower drying box adopts the horizontal circulation air supply mode with air circulation generated by the high-temperature resistant blower motor, and the hot air circulation drying.

The temperature in the box is uniform, and the temperature difference in the box can reach 2℃. The air is connected with the centrifugal wind wheel through the contactless blower motor and electrified.

Heat pipe, so as to send out hot air, then pass through the air duct to the inside of the oven, and then suck the used air into the air duct to become the air source for recycling and heating. Ensure the uniformity of indoor temperature. The electric heater is used to heat the hair dryer drying box, and the heating wire usually exposed in the air is easy to be oxidized due to high temperature and long-term heating, which affects the service life. The heater usually adopts electric heating tube, that is, the heating wire is located in the heating pipe, which can reduce the oxidation rate and prolong the service life, and at the same time transfer heat to the steel pipe and increase the heat conduction area. The temperature controller of the drying oven is used to control and display the temperature. When the temperature in the oven is lower than the set temperature, the temperature controller controls the heater to heat continuously or intermittently, thus controlling the temperature in the oven. Electric blast drying oven is widely used in industrial production. Similarly, the hair dryer is an essential experimental instrument in the laboratory and a constant temperature drying equipment in the industrial manufacturing process.
