[0002] Dry grinders are widely used in industries such as automobile manufacturing, automobile maintenance, mechanical equipment, woodworking furniture, and surface treatment of painted walls. Dry grinders are usually equipped with electric or pneumatic grinding heads for surface grinding operations. They can grind old paint, putty, sheet metal, and paint surfaces. The dust generated during the grinding process can also be collected and processed by dust collection components.

[0003] For example, the Chinese patent document with authorization announcement number CN218901163U discloses “a dust collection component and a dry grinder”, a dust collecting bucket is provided on the top of the base, an isolation compartment and an exhaust compartment are provided inside the fan compartment, a storage rack is provided on the top of the fan compartment, and a ring rack is provided on the top of the base; a dust collecting bucket is provided on the top of the base, and the air containing dust enters the dust collecting bag from the air inlet, and the dust collecting bag is wrapped on the outside of the dust filter element, thereby increasing the contact area between the dust collecting bag and the dust filter element, and the air filtered by the dust collecting bag enters the dust filter element for further filtration, and an exhaust compartment and an isolation compartment are provided inside the fan compartment, and the driving components such as the motor are located in the isolation compartment, and the air filtered by the dust filter element is discharged from the exhaust holes on the surface of the exhaust compartment to prevent dust from accumulating on the surface of the driving component inside the isolation compartment and affecting the operation of the driving component.

The dust bag and dust filter element will still be clogged during use, affecting the dust removal efficiency of the dry grinder and causing the dry grinder to be unable to effectively collect the dust generated during the grinding process.
