A spray bottle, as the name suggests, is a bottle that can form a spray. In life, spray bottles are a general term for devices that can artificially create fog.
The manufacturing principle of the spray bottle is to form a high-pressure system in the bottle, and the liquid in the bottle is sprayed out in the form of extremely fine water particles with a high pressure drop. Because these sprayed water particles are very similar in effect and form to natural fog, this kind of bottle is called a spray bottle.
