MESH PREFILTER FOR VACUUM DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240032750 titled 'MESH PREFILTER FOR VACUUM DEVICE

Simplified Explanation

The abstract describes a prefilter for a vacuum device that includes a frame with a base, a first cylindrical ring, a plurality of ribs, and a second cylindrical ring portion. The prefilter also includes a mesh layer coupled to the frame and an engagement feature to fasten the frame to the filter.

  • The prefilter is designed to be used in a vacuum device.
  • The frame of the prefilter extends in an axial direction between two extents.
  • The frame includes a base located at the first axial extent.
  • A first cylindrical ring extends axially from the base towards the second axial extent.
  • A plurality of ribs extend from the first cylindrical ring towards the second axial extent, creating openings between them.
  • A second cylindrical ring portion is positioned at the second axial extent of the frame.
  • The mesh layer is made up of multiple mesh openings and is attached to the frame.
  • The mesh layer covers the openings created by the ribs, preventing debris larger than the mesh openings from passing through.
  • The engagement feature is coupled to the frame and is used to fasten the frame to the filter.

Potential Applications:

  • This prefilter can be used in various vacuum devices, such as household vacuum cleaners or industrial vacuum systems.
  • It can be applied in air purifiers or HVAC systems to filter out larger debris before it reaches the main filter.

Problems Solved:

  • The prefilter prevents larger debris from entering the vacuum device or air purifier, reducing the risk of clogging or damage to the main filter.
  • It improves the overall efficiency and lifespan of the vacuum device by reducing the workload on the main filter.

Benefits:

  • The prefilter increases the effectiveness of the vacuum device by capturing larger debris before it reaches the main filter.
  • It reduces the need for frequent filter replacements or cleanings, saving time and maintenance costs.
  • The prefilter enhances the performance and longevity of the vacuum device by preventing damage caused by large debris.


Original Abstract Submitted

a prefilter for a filter of a vacuum device includes a frame extending in an axial direction between first and second axial extents. the frame includes a base located at the first axial extent, a first cylindrical ring extending axially from the base toward the second axial extent, a plurality of ribs extending from the first cylindrical ring towards the second axial extent and defining openings between the ribs, and a second cylindrical ring portion positioned at the second axial extent of the frame. the prefilter also includes a mesh layer comprising a plurality of mesh openings, the mesh layer coupled to the frame and configured to cover the openings to prevent debris larger than a size of the mesh openings from passing therethrough. the prefilter also includes an engagement feature coupled to the frame and configured to engage the filter to fasten the frame to the filter.
