Ejector Pump Integrated Filter Cartridge Vacuum System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum systems with filter cartridges are not simple or compact, leading to decreased vacuum response speed and increased vacuum loss due to long intake lines.
Innovation Solution
A vacuum system configuration where the ejector pump is directly mounted within a container-shaped filter cartridge, which serves as a vacuum chamber, incorporating an intake port, inflow port, and mounting port, with a filter and cap to facilitate rapid vacuum generation and low loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter cartridge is additionally mounted on the intake line, then dust and foreign materials are prevented from entering the ejector, but the vacuum system becomes more complex and less compact
Solution Approach 1:
The ejector is directly integrated into the filter cartridge housing, merging two previously separate components (filter cartridge and ejector) into a single unified structure. This eliminates the need for additional mounting on the intake line while maintaining both filtration and vacuum generation functions, thereby reducing system complexity and improving compactness.
2Reliability
If the filter cartridge is mounted on the intake line, then filtration is provided, but the intake line becomes longer causing decreased vacuum response speed
Solution Approach 1:
By integrating the ejector directly into the filter cartridge, the patent eliminates the separate intake line connection. The compressed air inlet is positioned directly at the filter cartridge, and the ejector operates within the same housing, significantly shortening the air path and improving vacuum response speed while maintaining filtration through the cartridge.
3Reliability
If the filter cartridge is mounted on the intake line, then filtration is provided, but vacuum loss is increased due to long intake line
Solution Approach 1:
The integration of the ejector within the filter cartridge housing eliminates long intake lines and reduces the number of connection points. This streamlined configuration minimizes pressure drops and energy losses associated with long air paths and multiple connections, thereby reducing vacuum loss while maintaining effective filtration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration results in a simple, compact vacuum system with rapid response to compressed air and reduced vacuum loss, enhancing overall performance.
Implementation Method 1
an ejector pump, which passes through the mounting port of the filter cartridge, is installed such that one end thereof is adjacent to or inserted into the inflow port
Implementation Method 2
When the compressed air flows through the ejector 1 at high speed, air in the pad 3 is drawn toward the enclosed space, which is in a vacuum state, and is discharged outside along with the compressed air
Implementation Method 3
a filter which is disposed in a space therein covered by a cap and filters air flowing in through the intake port

AI summary
Disclosed is a vacuum system capable of realizing a simple, compact configuration using a filter cartridge. The vacuum system makes use of a container-shaped filter cartridge, which includes an intake port, an inflow port for compressed air, and a mounting port in a sidewall thereof, and a filter which is disposed in a space therein covered by a cap and filters air flowing in through the intake port. An ejector pump passes through the mounting port of the filter cartridge, is installed such that one end thereof is adjacent to or inserted into the inflow port, and includes a through-hole formed in a nozzle body so as to communicate with the space inside the filter cartridge. In the state in which the ejector pump is mounted, the filter cartridge is used as a housing providing a vacuum chamber or an enclosed space.
