Abstract
A portable chemical spraying apparatus has an electric motor/compressor mounted inside of two halves of a lightweight housing. A compressed air output of the motor/compressor connects directly to a compression chamber. Compressed air inside of the compression chamber moves through the venturi of a nozzle into a mixing chamber. The mixing chamber opens to atmosphere through a vortex of compressed air received via spiral passages connecting to the compression chamber. Chemicals may be drawn into the mixing chamber through a needle, which may perforate a seal of a disposable chemical container at the time the chemical container is connected to the portable spraying apparatus. Simultaneously, the needle seals with a metered conduit which extends to the inside bottom of the chemical container.
