Spraying devices are tools designed to distribute liquids in a fine mist or spray. They are commonly used for various applications, including gardening, cleaning, and painting. These devices can range from simple hand-held spray bottles to more complex systems like spray guns and pesticide sprayers. Most spraying devices operate by using a pump mechanism or compressed air to create pressure, which forces the liquid out through a nozzle. This allows for even coverage and efficient use of the liquid being sprayed. Common examples include garden sprayers, airbrushes, and foggers.
