1. A generating device for simulating a particulate environment for an experimental animal comprising an experimental chamber, wherein an upper sealing device is arranged on an upper side of the experimental chamber; an excreta storage device configured to store animal excreta is arranged in an interior adjacent to a middle of the experimental chamber, and an ultrasonic atomization device is installed at a bottom adjacent to a center of the experimental chamber; an upper side of the ultrasonic atomization device is connected to a guide device for guiding particles;
the interior of the experimental chamber is provided with a bottom air supply chamber, a pulling chamber, and an experimental animal placement chamber in turn from bottom to top, wherein the experimental animal placement chamber has two sides which are fixedly connected to respective air pipes for inputting and outputting air, and a pulling port is arranged on a side of the pulling chamber;
the upper sealing device comprises an upper cover with a rectangular chamber, wherein the rectangular chamber penetrates through a bottom of the upper sealing device; a connecting bar is fixedly connected to a bottom side wall of the upper cover, and a receiving bar is fixedly connected to an outer side wall adjacent to a top of the experimental chamber; the receiving bar and the connecting bar are attached to each other and connected by a first screw;
the excreta storage device comprises a drawer adapted to fit within the pulling port, and an interior of the drawer is provided with a storage chamber, wherein the storage chamber penetrates through an upper side of the drawer; and
the guide device comprises an air seal cover, wherein a micro fan configured to drive a movement of one or more particles generated in the ultrasonic atomization device is installed inside the air seal cover; air guide pipes are fixedly connected to a side wall of the air seal cover; a bottom of the air seal cover is connected to an interior adjacent to a bottom side of the bottom air supply chamber by a second screw; one end of the ultrasonic atomization device is arranged inside the air seal cover; and one end of each of the air guide pipes penetrates through the pulling chamber and extends into an interior of the experimental animal placement chamber.
