Abstract
A battery-powered apparatus, for inducing air flow past a product capable of being vaporized, includes a compact housing that comprises a hollow outer shell and a hollow, generally cylindrical inner shell, having an axis, on which the operating components of the apparatus are supported. The inner shell is mounted with the outer shell by a hinge to pivot substantially on the axis between closed and open positions. In the closed position the inner shell compliments the outer shell to define an enclosed space and shield the apparatus components. In the open position, the inner shell is nested within the outer shell to expose the apparatus components. The product and a battery for powering the apparatus may be assembled into a cartridge formed to be received in the apparatus housing. Electrical battery contacts and a support for the cartridge in the housing are also disclosed.
