A DEVICE WITH AN MOTOR DRIVEN IMPELLAR PUMP AND AN ELECTRONICALLY AND MANUALLY ACTUATED AIR VALVE FOR CONTROLLING THE FILLING AND EXHAUSTING OF AN AIR CUSHION

摘要

A device for controlling air filling and air exhausting of an air cushion includes a casing provided inside with a motor controlled by a wire controller and a fan blade, and an upper cover mounted on the casing. An air-exhausting nozzle closed by a film is provided outside the casing. A support plate is positioned above the fan blade, fixed on an upper surface with a transformer and an electromagnetic valve controlled by the wire controller. A push plate is combined on a front end of the magnetic rod of the electro-magnetic valve, having a push rod protruding through the casing and extending in the air-exhausting nozzle to push open the film. Then this device can be controlled by wire controlling or manual controlling to adjust resilience of an air cushion.
