This utility model relates to the field of oven equipment technology, specifically an infrared oven with a self-cleaning function. It includes an infrared oven body, with several supporting columns evenly fixedly installed at the bottom of the oven body. A load-bearing base plate is fixedly installed at the bottom of each supporting column. An adjustable cleaning mechanism is provided on one side of the top of the infrared oven body. This self-cleaning infrared oven, through the adjustable cleaning mechanism, uses a micro-motor to drive a transmission screw to rotate, causing a sliding nut block to move up and down along a limiting groove. This, in turn, drives the supporting limiting connecting rod, L-shaped bracket, vacuum head, and cleaning brush to achieve height adjustment. This design effectively solves the problem of inconvenient height adjustment of cleaning components in existing technologies. It can precisely adjust the contact height and force between the cleaning brush and the surface to be cleaned (such as a conveyor belt) according to different cleaning needs, improving the cleaning effect and enhancing the flexibility of cleaning use.
