[0002] Industrial vacuum cleaners (sweepers) are widely used in many fields such as metal processing, chemical production, textiles, machinery processing, and food processing to collect dust, debris, liquids and other pollutants generated in industrial environments.

[0003] Traditional sweepers use electric motors as their drive source. However, with industrial development, workshops and processing sites in industrial environments now have certain safety and explosion-proof requirements. Therefore, traditional electric vacuum cleaners are not suitable for this working condition. There is a need to propose a sweeper based on a pneumatic power source. At the same time, the lifespan of the internal filter element of the pneumatic sweeper also needs to be considered to improve the user experience and practical effect. Utility Model Content

[0004] This application addresses the shortcomings of the prior art by providing a pneumatic cleaner based on a pulse vibration filter element. It uses compressed air as a power source and an ejector as a fluid transmission component. Under the action of compressed air, the negative pressure port of the ejector creates negative pressure acting on the receiving chamber. This negative pressure passes through the internal filter module and ultimately reaches the end suction grip head, thus achieving a non-electric, explosion-proof filtration and dust collection effect. Simultaneously, to improve the service life of the filter element module, a pulse generator is installed below the filter element module, capable of intermittently performing high-frequency physical vibrations to shake off dust adhering to the filter element module, thereby significantly extending the filter element's lifespan.
