The embodiment of the utility model provides a protective device. The protective device comprises an air inlet component and an air outlet component, rectifying member, the fan is arranged below the air inlet component and is opposite to the air inlet component; wherein the flow regulating member has a central convex shape including an inclined surface portion linearly extending from a top of thecentral convex shape to a bottom of the flow regulating member, and wherein at least a portion of an inner surface of the air intake member from the bottom is parallel to an outer surface of the inclined surface portion of the flow regulating member to form a gap therebetween. By utilizing the scheme of the embodiment of the utility model, the high-speed air flow formed by the gap eliminates the influence on a protected object caused by a physical shielding mode, and the formed protective air wall can be close to the surface of the protected object as much as possible, so that the protective effect is greatly enhanced
