"spray gun" 的定义和意义

What is a "spray gun"?

A spray gun is a tool used for applying paint or other liquids in a smooth, even mist or spray. It has a handle, a trigger, and a tip through which the liquid is sprayed. Spray guns are commonly used for painting large surfaces quickly and evenly, such as walls, vehicles, and furniture. They work by mixing the paint with air or another substance and then sending it out through the tip. Spray guns can be adjusted to control the spray pattern and flow, making them suitable for both wide coverage and detailed work.
