[0026] An infrared smoke screen application device, such as Figures 1 to 5 As shown, it includes a box 1, which is mainly used to install various components of the entire device and store infrared materials. Specifically, the box is divided into an upper storage chamber 3 and a lower working chamber 4 by a partition 2, and a feed discharge port is provided on the partition, and a feed port is provided on the top plate of the box. In order to facilitate the transportation and installation of the box, handles 5 can be symmetrically provided on both side panels of the box.
