ABSTRACT:
The present invention relates to a rescuing helmet having an illuminating device, a heat resistant helmet body, a fastening strap, a controlling unit and a compressed air tank. The heat resistant helmet body is provided with an air conduct for connecting a hose. The lower peripheral of the helmet body is provided with a resilient strap and the lower portion of the resilient strap is provided with a fastening strap. The other end of the fastening strap is connected with an air tank. The top outlet of the air tank is provided with a controlling unit which is configured with a metering throttle, a cover and a light triggering device. The metering throttle is provided with an air supplying duct to supply the fresh air to the helmet body via a hose. In use, the user may readily wear the helmet body and dispose the air tank in front of the chest. The metering throttle is then switched on such that a metered flow of air is supplied to the helmet body. Meanwhile, the light is also simultaneously triggered to light a rescue or escape path. The rescuing helmet features a simple, compact configuration which is affordable by all people. Most important, the rescuing device may save the life of the user during a fire.
