The air dredging device for medical vehicles usually consists of parts such as a filter, a fan, a controller, a humidity regulation system, sensors and an alarm system, a ventilation opening and an air outlet.

[0003] The prior art publication number CN217129577U discloses a mine air dredging device for coal mining, belonging to the technical field of coal mining. It includes an air duct. A fan is installed inside the air duct through a bracket. One end of the air duct is connected with a flange. An installation seat is connected to the outside of the air duct. A connection structure is provided on the upper part of the installation seat. The connection structure includes a lead screw, a sliding plate, a limiting hole, a notch and a sliding strip. The lead screw is threadedly connected to one side of the installation seat. The sliding plate is slidably connected to the inner top of the installation seat. The limiting hole is opened at the center position of one side surface of the sliding plate. By setting the connection structure and rotating the lead screw to make the lead screw away from the sliding plate, the sliding plate can be translated.
