Cyclone Chamber Layout for High-Velocity Vacuum Dirt Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclonic dust separation devices in vacuum cleaners face challenges with inefficient dirt separation due to high RPM motors causing shaft critical speed vibration issues and the need for larger motors, which increases weight and complexity, while existing designs compromise airflow and energy efficiency.
Innovation Solution
A cyclonic separation device with a cylindrical cyclone chamber, tangential inlet, baffle plate, tangential dirt outlet, and center exit duct, positioned on the output side of the suction fan, allowing for higher air velocity and reduced motor size, minimizing flow blockages and weight, and enabling efficient dirt separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a long shaft is used to connect the motor to the fan through the cyclone chamber, then the center of gravity is lowered, but shaft critical speed vibration problems occur and weight reduction is prevented
Solution Approach 1:
The invention extracts the motor from the cyclone chamber and relocates it to the handle assembly, eliminating the need for a long shaft through the cyclone chamber. This removes the source of vibration problems and allows for weight reduction while maintaining stable center of gravity through alternative means.
Solution Approach 2:
The invention introduces an intermediary airflow path where air flows from the cyclone chamber outlet to the fan inlet, allowing the motor and fan to be positioned separately without requiring a direct mechanical connection through the cyclone chamber, thus avoiding vibration issues.
2Reliability
If the cyclone separator chamber is placed on the suction side of the fan, then clean air is pulled through the fan, but air velocity and energy are reduced
Solution Approach 1:
The invention inverts the conventional arrangement by placing the cyclone separator chamber on the discharge side of the fan instead of the suction side. This allows the fan to generate high velocity air flow that drives the cyclone separation process, significantly increasing air velocity and energy availability while the separated clean air is discharged through the handle.

Implementation Method 1
a suction fan driven by the motor and including a plurality of fan blades driven at a high velocity by the suction fan motor to suck a fluid from a first side of the fan to the second side of the fan
Implementation Method 2
fluid flows from the pick up head through the tangential inlet into the first cyclone chamber and rotates therein at high velocity such that particles in the fluid are forced out to the inner surface of an outer wall of the first cyclone chamber
