Abstract

Abstract A telescopic double wall air intake device having an antenna including an air intake canister attached to one end of the antenna and an air plenum arranged on the other end of the antenna. The air canister has disposable filtering material therein. The air plenum is attached to a frame of a car or other vehicle and carries the pneumatic or electric motor for moving the telescopic air intake device up and down. The air plenum may also be connected to a radio and other communication devices. The inlet side of a high static air moving device, e.g., an air booster fan, is connected to the air plenum via a flexible duct. The discharge side of the booster fan is connected to a second air plenum, e.g., an air mixing plenum, via a flexible metal air duct. The air mixing plenum has three connection ports, two of which are used for inlet flows and one of which is for discharge flow. The inlet ports are provided with check valves. The check valve in one of the inlet ports prevents air from travelling backwards to the booster fan. The other inlet port is connected to a conventional air inlet grille through a flexible metal duct. The discharge side of the air mixing plenum is connected to the conventional air distribution inlet of a car to provide air-conditioning inside the car cabin.
