The air channel may be provided in the handle or in a separate conduit attached to and running along the handle. There may be several air outlets all communicating with the channel or this may be a nozzle which can be swivelled to two or more different portions to direct the air flow as desired. A manually operable switch is provided on the handle by means of which air flow can be chosen or interrupted as desired.
