Ejector Assembly Mounting on Cylindrical Pipe for Vacuum Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum pumps require a specific housing and partition walls to install and utilize the ejector, making it difficult to mount and assemble, and the ejector is ineffective in being individually utilized and manufactured.
Innovation Solution
A cylindrical ejector assembly with a supply hole, discharge hole, and through holes, along with support parts that include extended lines and ring-shaped protrusions, allowing the ejector to be mounted in a cylindrical pipe member without a specific housing, enabling easy assembly and disassembly, and a housing that can be separated into parts for improved applicability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specific housing with partition walls is used to install the ejector, then the ejector can be mounted and function, but the assembly becomes complex and the ejector cannot be individually utilized
Solution Approach 1:
The ejector is extracted from the complex housing structure and mounted directly on a cylindrical pipe member. The support parts are simplified to just what is needed for mounting the ejector on the pipe, eliminating unnecessary partition walls and housing components. This allows the ejector to be individually utilized while reducing overall device complexity.
2Ease of manufacture
If a dedicated housing is designed for the ejector, then the ejector can be installed, but the manufacturing and assembly process becomes complicated
Solution Approach 1:
The cylindrical pipe member serves multiple functions: it acts as the structural support, the mounting base for the ejector, and the housing for the vacuum chamber. This universal component eliminates the need for separate dedicated housing designs, simplifying both manufacturing and assembly processes while maintaining proper ejector installation.
3Adaptability or versatility
If the housing is separated into parts, then applicability is improved, but the structural integrity may be compromised
Solution Approach 1:
The housing is segmented into a cylindrical pipe member and separate support parts that can be independently manufactured and assembled. The ejector assembly is mounted on the pipe member, allowing the system to be configured for different applications while maintaining structural integrity through proper mounting connections.

Function Achieved in This Case
The ejector assembly forms a closed vacuum chamber within a cylindrical pipe member, allowing for simple installation and operation of a vacuum pump without a dedicated housing, enhancing applicability and ease of assembly and disassembly, and allowing directional changes in suction ports for improved functionality.
Implementation Method 1
compressed air is supplied to the inlet chamber C1, rapidly passes through the plurality of nozzles 4a, 4b, and 4c of the ejector 3 in sequence, and is discharged outwards via the discharge chamber C3. At this time, inside air of the suction cup 5 is introduced into the ejector 3 so as to be discharged with the compressed air. In this discharge process, a vacuum and negative pressure are generated in inner space of the suction cup 5

AI summary
The present invention relates to an ejector assembly and a vacuum pump, the ejector assembly including a typical cylindrical vacuum ejector and a support part. The support part includes a first support having a supply line extending outwards from a hole in which a first end of the ejector is mounted, and a second support having a discharge line extending outwards from a hole in which a second end of the ejector is mounted. Further, the first and second supports facing each other are configured such that the outer circumferential surfaces thereof are in contact with the inner circumferential surface of a pipe member so as to form a space between the first and second supports, the space communicating with through holes. In the vacuum pump using the ejector assembly, the pipe member is a housing, and the space is a vacuum chamber formed in the housing.
