Energy-saving radio frequency hot air generator

Abstract

The energy-saving type radio frequency hot air generator comprises an air conveying pipe main body, a radio frequency generation mechanism, a purification mechanism, an outlet hot air temperature detection mechanism and a polycrystalline silicon carbide heating pipe, the radio frequency generation mechanism is embedded in the inner side of the air conveying pipe main body, and the polycrystalline silicon carbide heating pipe is arranged at the middle end of the air conveying pipe main body; a fan is arranged on one side of the outer portion of the air conveying pipe body, a power supply port is formed in one side of the outer wall of the fan, and a purification mechanism is arranged at one end of the outer portion of the air conveying pipe body. According to the energy-saving type radio frequency hot air generator, based on the principle that the distances between the round edge and the circle center shaft are the same, it is guaranteed that the distances between the peripheral radio frequency generators and the polycrystalline silicon carbide heating pipes are the same, heating uniformity is guaranteed, and therefore hot air is more constant in temperature and more stable, and due to the filtering function of the air purification mechanism and the spiral structure of the polycrystalline silicon carbide heating pipes, energy is saved. The radiation frequency emitted by the radio frequency generator can be absorbed to the maximum extent, so that acting heating is increased to the maximum extent.
