<p>A portable spray for plants etc. is powered by a battery driven electric motor, with a set of batteries housed inside the handle. This handle is made in two parts, the upper part holding the batteries, which can be removed from the lower part, for reducing the length when not in use. The lower part is attached to a bracket with a toothed part moved against a set of pegs to adjust its angle, and locked by a butterfly unit. This bracket carries the motor and rotary spray and also supports a flask containing the liquid to be sprayed. The whole device is rotated from a position with the flask resting on the ground, to a position in which the flask is inserted so that it delivers the liquid directly to the rotary spray. All the electrical connections are made inside the handle.</p> |
