AI Technical Summary

Technical Problem

Existing grass trimmers are prone to stopping during operation due to grass tangling around the rotating head, and the reduced gap between the machine casing and the trimming head leads to poor heat dissipation.

Method used

An isolator is installed in the grass trimmer head, along with a rotating component and a cutting component. The rotating component generates airflow that is blown out through the air outlet, while the cutting component cuts the weeds, preventing tangling and dissipating heat.

Benefits of technology

It effectively prevents weeds from tangling around the motor output shaft, maintains good heat dissipation of the equipment, reduces the risk of machine downtime, and improves operational stability and lifespan.

Abstract

本申请涉及园林工具领域，具体公开了一种打草头及打草机，其中，打草头包括机壳，安装在机壳内的马达，安装在机壳一侧，并由马达向其提供旋转驱动力的打草头组件，设置在机壳一侧的马达支架，设置在机壳和打草头组件之间的隔离件，安装在隔离件内侧的旋转件，隔离件为风叶罩，旋转件为风叶，风叶罩上安装有切割件，隔离件能够引导散热气流的同时，还能够隔离保护风叶。风叶罩上设有出风口，在风叶旋转的过程中，其所产生的气流能够经由出风口并从隔离件的内侧向外侧吹出；风叶旋转的过程中，切割件能够对隔离件内侧的杂草进行切割，切割后的杂草能够被风叶产生的气流吹向隔离件的外侧，能有效防止杂草进入打草头内部出线缠草问题。
