Definitions
- the present invention involves a back sprayer with in-built system for air compression in the product tank by means of an incorporated battery-supplied electric compressor.
- This invention improves a traditional (manually operated) back sprayer and thus solves the problem of repeated taking-off and pumping of back sprayers. Besides, in terms of environmental protection, the operation of this back sprayer has no adverse environmental impact as compared to back-sprayers with internal combustion motor drive. TECHNICAL BACKGROUND
- the main objective of the invention is the installation of an air compression system in the back sprayers that will meet the highest environmental requirements and to achieve a constant preset pressure within the sprayer cylinder, reduction of noise during the motor operation, automatic air compression control, very small weight of the sprayer.
- the sprayer cylinder (to which other component parts of the electric compressor, shoulder strap, battery, pressure switch, two outlets and one air inlet valve are mounted).
- Electric compressor designed for D.C. power supply from the batteries mounted on the sprayer cylinder.
- the switching box incorporates a switch for the switching-on of the compressor, connected also to the pressure switch that controls the pressure within the sprayer by switching the compressor on and off; a socket for battery charging without dismantling from the sprayer cylinder, and a socket for the sprayer connection to a single-phase power supply over an adapter, which can also be used for the connection to a car battery supply.
- Sprayer gun handle (with valves and hose)
