[0002] A leaf blower is a gardening tool that is mainly used to clean up leaves, grass clippings and other debris outdoors. Its working principle is based on aerodynamics. The internal motor drives the fan blades to rotate at high speed, generating a strong airflow, which is then accelerated and blown out in a directional manner through a specific nozzle. When the leaf blower is working, the strong airflow it generates can quickly blow away light debris such as leaves and grass clippings on the ground, causing them to move with the wind direction, thereby achieving the purpose of cleaning. This tool is particularly suitable for cleaning large areas of fallen leaves and grass clippings, which can greatly improve cleaning efficiency and reduce manual labor intensity.
