The infrared heating tube of the disinfection cabinet uses the characteristics of infrared rays. Through effective heating of the object, the temperature inside the disinfection cabinet rises to 200~300 degrees Celsius, thereby achieving the purpose of disinfection. Compared with traditional light bulbs, light bulbs use electric energy to heat Tungsten filaments become incandescent to emit light, using "light energy", while heating tubes use heat.

When using the infrared heating tube disinfection cabinet, it is necessary to prevent the infrared heating tube electrode from being damp and oxidized. Contact resistance appears at the socket of the infrared heating tube, which will easily burn the tube socket or other parts and shorten the service life of the disinfection cabinet.
