Abstract
A portable, battery-powered sprayer for dispensing two liquid products at the same time includes first and second nozzles which receive first and second liquids and first and second air supplies. The nozzles are arranged to dispense the liquids at different flow rates, with different droplet sizes, and into different target zones. A low battery sensor prevents operation when the batteries have insufficient power to produce the intended flow rates and droplet sizes.
Claims66
A portable sprayer, comprising:
- a housing having first and second nozzles mounted in the housing, the nozzles being constructed such that the droplet sizes produced by the two nozzles are different from one another;
- a reservoir cartridge in the housing defining first and second liquid chambers;
- pressurizing means in the housing for supplying liquid from the first and second chambers to the first and second nozzles, respectively, under pressure suitable for creating the desired droplet sizes;
- air supply means in the housing for supplying air to the first and second nozzles, the pressure and volume of the supplied air being suitable for creating the desired droplet sizes;
- and
- control means in the housing for controlling operation of the pressurizing means and air supply means.
