  • Patent number: 11231206
    Abstract: A lid for a heat generating device in which the heat generating device has a body with a combustion chamber disposed therein. The lid includes an air moving device, an air intake housing, and a hinge. The air moving device is configured to generate a flow of air. The air intake housing is disposed between the lid and the air moving device. The air intake housing extends out from the lid to cantilever the air moving device out from the lid. The hinge is disposed between the lid and the body and proximal to the air intake housing. The hinge is configured to provide a pivot for the lid. A weight of the air moving device counter balances at least a portion of a weight of the lid to ease pivoting of the lid into an open position.
