Ion Generator Nozzle Tapered Surface Air Amplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ion generators require increased energy consumption to enhance the static elimination effect by increasing the flow rate or pressure of compressed air, which is inefficient and may lead to foreign substances adhering to the discharge electrode.
Innovation Solution
An ion generator design featuring a nozzle with a tapered surface and auxiliary air guide holes that incorporate outside air into the compressed air flow, allowing for enhanced static elimination without increasing the compressed air flow rate or pressure, and an ejection head that covers the nozzle and serves as the opposite electrode to ionize the amplified air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flow rate or pressure of compressed air is increased to enhance the static elimination effect, then the static elimination effect is improved, but the energy consumption is increased
Solution Approach 1:
The tapered surface acts as an intermediary structure that utilizes the compressed air flow to create a suction effect, drawing in outside air through the air introduction hole. This mediator mechanism allows the system to amplify the total air flow without directly increasing the compressed air supply, thereby enhancing static elimination while maintaining energy efficiency.
Solution Approach 2:
The invention changes the physical parameters of the air flow system by introducing a tapered surface with a specific angle range (10-45 degrees) and positioning the air introduction hole at a specific location. These parameter changes create optimal conditions for outside air to be drawn in and mixed with the compressed air, achieving enhanced static elimination effect without proportionally increasing energy consumption.
2Reliability
If the flow rate or pressure of compressed air is increased to enhance the static elimination effect, then the static elimination effect is improved, but foreign substances may adhere to the discharge electrode
Solution Approach 1:
The tapered surface serves as an intermediary that directs the compressed air flow to create a controlled suction zone. This intermediary structure ensures that outside air is drawn in through the designated air introduction hole rather than allowing uncontrolled infiltration, thereby preventing foreign substances from reaching and adhering to the discharge electrode while still achieving the desired static elimination effect.
Solution Approach 2:
The invention extracts only the beneficial outside air through the controlled air introduction hole positioned on the tapered surface, while the tapered structure itself acts as a barrier that prevents foreign substances from the surrounding environment from entering the discharge area. This selective extraction approach enhances static elimination without introducing harmful contaminants.
3Reliability
If outside air is involved in the compressed air flow to spray more air ions, then the static elimination effect is enhanced, but the complexity of the device structure is increased
Solution Approach 1:
The invention merges the functions of air supply and outside air introduction into a single integrated nozzle structure. The air introduction hole is directly formed on the tapered surface of the nozzle, combining the compressed air delivery function with the outside air suction function. This merging approach achieves enhanced static elimination effect while minimizing structural complexity by avoiding separate components for each function.
Solution Approach 2:
The nozzle structure is designed with multi-functionality: it serves as both the compressed air delivery channel and the outside air introduction mechanism. The tapered surface with the air introduction hole performs dual functions of directing compressed air and creating suction for outside air. This universal design achieves enhanced performance without increasing device complexity.

AI summary
An ion generator 10a has an ejection head 18 as an opposite electrode and a discharge electrode 16, and generates air ions by corona discharge. A nozzle 14 supporting the discharge electrode 16 is attached to a base member 12 formed with an air supply path 11, and the nozzle 14 is formed with an exposure surface 24 for exposing the tip end portion 16b of the discharge electrode 16 and a tapered surface 25. The nozzle 14 is formed with air guide holes 26 which communicate with the air supply path 11, and ejection ports of the air guide holes 26 are open on the tapered surface 25. Compressed air ejected from the ejection port is flowed along the tapered surface 25 so that outside air surrounding the nozzle 14 is involved in the compressed air, and sprayed in a front direction of the discharge electrode 16.
