The present disclosure provides a scene simulation device includes a housing with a scene space, flocs, a transport pipeline and a fan which are arranged in the housing. One end of the transport pipeline is communicated to a bottom of the scene space, and the other end is located at a position, close to a top of the scene space. The flocs are configured to enter the transport pipeline along the bottom of the scene space, are transported along the transport pipeline when the fan is started, and are sprayed out from a top of the transport pipeline. A dispersing component configured to disperse the flocs sprayed out of the transport pipeline is arranged in the scene space. The falling range of the flocs can be expanded, and the mechanical unreality caused by the small falling range of the flocs is prevented, so as to better create a scene atmosphere.
