[0021] In this embodiment, the protection box 1 provides a closed and safe environment for protecting the infrared thermal imager 2 from dust and stains in the external environment. The infrared thermal imager 2 can be slidably installed in the protection box 1 and can enter and exit through the opening 3. The soft brush 4 is slidably installed in the protection box 1 and works in conjunction with the infrared thermal imager 2. When the infrared thermal imager 2 needs to be used, the soft brush 4 will first perform a preliminary cleaning on its lens to effectively remove large particles of dust and stains. The installation box 5 is fixedly installed on one side of the protection box 1, and a rack 6, a driving gear 7 and a driving motor 8 are installed inside. One end of the rack 6 is connected to the soft brush 4. The drive gear 7 is connected to the rack 6, and the output shaft of the drive motor 8 is connected to the drive gear 7. When the drive motor 8 is started, the drive gear 7 will drive the rack 6 and the soft brush 4 to slide in the protection box 1, so as to realize automatic cleaning of the lens of the infrared thermal imager 2.
