Abstract: A powder ejector comprising a casing having a pump mounted thereon and driven by a motor. The casing defines a battery confinement space which is accessible through an openable cover. The batteries positioned within the space are connected with the motor by an electrical circuit which is suitably opened and closed by a manually actuatable trigger switch device. A powder container is removably mounted on the casing and an air pipe communicates between the motor and the powder container for pressurizing same. The casing has a nozzle mounted thereon, and a transmission pipe communicates between the powder container and the nozzle for permitting powder to be ejected.
