[0002] An angle grinder, also known as a grinder or disc grinder, is a handheld electric tool that uses fiberglass for cutting and grinding. It is mainly used for cutting, grinding and brushing metals and stones. Whether the angle grinder is cutting or grinding, it will generate a lot of dust, causing environmental pollution and affecting the health of workers. For example, as shown in the angle grinder with Chinese patent application number CN202222973967.0, when in use, push the switch to energize the drive motor, and the drive motor drives the grinding wheel to rotate through the active gear and the driven gear, and then the grinding wheel is extended into the space to be polished to grind the surface of the object.

[0003] However, since dust covers are used to prevent dust during the operation of the angle grinder, it is not known that during the high-intensity and long-term cutting and grinding process, dust often enters the machine body from the air inlet, causing a large amount of dust to accumulate on the machine body, thus affecting the operation of the angle grinder.
