At present, a plurality of infrared heating lamp tubes adopt 360-degree infrared heating, and heat in the direction not needing heating, so that objects not needing heating are damaged by infrared radiation, and energy waste is caused. If the infrared reflecting cover is arranged on the side which does not need to be heated, the occupied space of the device is increased, the cost is increased, the radiated infrared heat energy cannot be reflected by the reflecting cover, and partial heat energy bypasses the reflecting cover and acts outside the reflecting cover.
