This utility model relates to the field of infrared imager technology, and specifically discloses an infrared imager for detecting volatile organic compound (VOC) leaks. It includes a detection host, a detection lens, and a support pan-tilt unit. When the device encounters an external impact, the main protective shell, buffer connecting seat, and light-transmitting protective plate form the first line of defense, directly preventing tools, parts, and other external objects from directly contacting the detection lens. This avoids scratching the high-precision optical lens, thereby preventing infrared signal acquisition distortion and ensuring the accuracy of VOC leak detection. If the impact force acts on the front of the light-transmitting protective plate, the two return springs between the light-transmitting protective plate and the main protective shell are compressed synchronously. The elastic deformation of the springs absorbs the impact force, reducing the transmission of the impact force to the buffer connecting seat, the main protective shell, and the inside of the detection host. This protects precision components such as the infrared detector and signal processing module, preventing malfunctions such as decreased detector sensitivity and effectively extending the overall service life of the equipment.
