Solution Overview
Problem
In vortex ring generation devices, the discharge component may not be reliably applied to an object due to uneven distribution along the circumferential direction in the vortex ring discharged from the discharge port.
Innovation Solution
The vortex ring generation device ensures a wide circumferential supply of the discharge component by making the total circumferential length of the component supply port at least half of the discharge port, with an annular shape located adjacent to the discharge port, utilizing dynamic air pressure to evenly disperse the component, and reducing backflow through a vibrating extrusion mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a component supply port is used to supply discharge component to the vortex ring, then the discharge component can be contained in the vortex ring, but the discharge component becomes unevenly distributed along the circumferential direction
Solution Approach 1:
The component supply port is divided into multiple segments arranged circumferentially around the air passage. Each segment supplies discharge component to a specific angular position, ensuring uniform circumferential distribution. The segments are positioned at different angular locations to cover the entire circumference, transforming a single-point supply into a distributed multi-point supply system.
Solution Approach 2:
Different regions of the component supply port are designed with locally optimized characteristics. Each segment is positioned to supply discharge component to its corresponding angular position, creating localized supply zones. This allows the system to achieve uniform overall distribution through optimized local supply characteristics at each angular position.
2Ease of manufacture
If the component supply port is located far from the discharge port, then there is enough space for component supply, but backflow of air occurs and reduces discharge component application reliability
Solution Approach 1:
The component supply port is positioned upstream of the discharge port in the airflow direction, allowing discharge component to be supplied to the air passage before the air reaches the discharge port. This preliminary supply ensures that the discharge component is already mixed with the air flow, preventing backflow-related application failures and ensuring reliable delivery to the target object.
Solution Approach 2:
The air passage acts as an intermediary medium between the component supply port and the discharge port. The discharge component is first supplied into the air passage where it mixes with the air flow, and this pre-mixed air-component flow then moves to the discharge port. This intermediary mixing process ensures stable and reliable component delivery while accommodating spatial requirements.

Function Achieved in This Case
This configuration ensures uniform distribution of the discharge component over the entire circumference of the vortex ring, reducing uneven application and backflow, thereby stabilizing the vortex ring formation and maintaining component efficacy.
Implementation Method 1
air is extruded by an extrusion mechanism, thereby a vortex ring is formed and discharged from the discharge port
Implementation Method 2
the discharge component is sucked from the component supply port by using dynamic pressure of the air

AI summary
A vortex ring generation device includes a component supply port (60) surrounding the air passage (C) or the discharge port (25), and through which a discharge component is supplied into air. The total circumferential length L1 of the component supply port (60) is equal to or longer than 1/2 of the total circumferential length L2 of the discharge port (25).
