IMPELLER AND CLEANER USING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240225393 titled 'IMPELLER AND CLEANER USING SAME

The abstract describes a cleaner with an impeller that generates suction force to suction air into the body from a dust case through an air passage.

The impeller includes a boss portion fixed to the shaft, a base portion with increasing diameter from intake side to discharge side, and multiple blades.
Each blade has a wind cutting edge with a proximal end and a protruding end, positioned behind the proximal end in the rotation direction, closer to the intake side than the boss portion, and a wind sending edge farther from the boss portion than the wind cutting edge.

Potential Applications: - Household vacuum cleaners - Industrial cleaning equipment - Automotive cleaning tools

Problems Solved: - Efficient air suction - Improved cleaning performance - Enhanced dust collection

Benefits: - Increased suction power - Better cleaning results - Reduced maintenance needs

Commercial Applications: - Manufacturing and selling vacuum cleaners - Providing cleaning services - Supplying components for cleaning equipment

Questions about the technology: 1. How does the impeller design improve suction efficiency? 2. What advantages does the increasing diameter base portion offer in terms of air flow?

Frequently Updated Research: - Ongoing studies on impeller design for enhanced suction power - Research on blade configurations for optimal cleaning performance

Original Abstract Submitted

a cleaner including a body, a dust case, a shaft, a motor to rotate the shaft, and an impeller that rotates by the rotation of the rotation shaft by the motor to generate a suction force for suctioning air into the body from the dust case through an air passage, the impeller including: a boss portion fixed to the shaft, a base portion extended from the boss portion and having a diameter that increases from an intake side toward a discharge side of the air passage, and a plurality of blades on the base portion, each blade including: a wind cutting edge having a proximal end, and a protruding end, is behind the proximal end in a rotation direction of the impeller, and is closer to the intake side than the boss portion and a wind sending edge that is farther from the boss portion than the wind cutting edge.
