  • Patent number: 5993428
    Abstract: A head covering with eye spraying capability is described. A hard-hat like device incorporates a liquid spraying system between the layers of the head covering for use in environments in which the user may be subject to dirt or dust entering his eyes while working. The invention consists of a digitally activated pump connected by tubing to a reservoir containing water or special eye washing fluid. The reservoir is connected by tubing to one or more spray heads mounted on malleable tubing adjacent the user's face. The tubing supporting the spray heads may be changeably fixed by the user to provide accurate spraying into the user's eyes. A series of one way valves permit air to be replaced in the pump after activation while pressurizing the reservoir and forcing fluid out of the reservoir and through the spray heads and into the user's eyes.
