"snow blower"的定义和意义

What is a "snow blower"?

A snow blower is a machine used to remove snow from driveways, sidewalks, and other areas. It works by using a rotating blade to scoop up the snow and throw it out through a pipe. Snow blowers can be powered by electricity, gas, or battery, and come in various sizes, from small models for light snow to larger ones for heavy snow. They are more efficient than shovels, allowing for faster snow removal and reducing physical effort. Snow blowers are commonly used in areas with heavy winter snowfall to keep pathways clear and safe.
