Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grease guns for large mechanical components require dual air pressure sources, leading to intermittent and uneven grease flow, necessitating manual spreading and reducing operational efficiency.
Innovation Solution
A lubricant atomizing device for grease guns featuring a flow diverter switch that divides air pressure into two streams, using a single air pressure source to uniformly refine and spray grease through a multi-stage inner hole and refinement tube nozzle, with a constriction section and flexible tube to ensure smooth and uniform application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If dual air pressure sources are used to spray grease over large surface areas, then the spraying coverage is improved, but the grease flow becomes intermittent and uneven
Solution Approach 1:
The air pressure source is divided into two separate channels: a first air pressure channel that provides stable base pressure for continuous grease flow, and a second air pressure channel that provides additional pressure bursts. This segmentation allows each channel to perform its specific function independently, maintaining flow uniformity while achieving large area coverage.
Solution Approach 2:
A flow stabilizing component is introduced as an intermediary element between the air pressure sources and the grease discharge. This component mediates the interaction between the two air pressure channels, ensuring that the combined pressure effect produces smooth, uniform grease flow rather than intermittent bursts.
2Duration of action of moving object
If dual air pressure sources are used to extend spraying time, then the duration of lubrication is improved, but the grease forms large clumps requiring manual refinement
Solution Approach 1:
The first air pressure channel maintains continuous, stable pressure on the grease throughout the spraying duration, preventing the formation of large clumps. This continuous action ensures that grease flows smoothly and uniformly over extended periods without requiring manual intervention for refinement.
Solution Approach 2:
The grease discharge system incorporates a specially designed nozzle with varying hole diameters along its length. The hole diameter decreases from the inlet toward the outlet, creating different local flow characteristics that progressively atomize the grease. This local variation in geometry ensures fine, uniform spray quality throughout the entire spraying duration.
3Device complexity
If a single air pressure source is used, then the device complexity is reduced, but the grease flow lags behind air pressure operation
Solution Approach 1:
The first air pressure channel is configured to act on the grease before the second channel, creating a preliminary pressure buildup. This preliminary action prepares the grease for rapid discharge, ensuring that the grease flow responds immediately to air pressure application without lag, even though only a single air pressure source is used.
Solution Approach 2:
The flow stabilizing component is designed with dynamic characteristics that allow it to rapidly respond to changes in air pressure. The component's geometry and material properties enable it to translate air pressure changes into immediate grease flow changes, maintaining high response speed while using a single, simpler air pressure source.

AI summary
A lubricant atomizing device for a grease gun involves refined spray-on grease for the external surfaces of large mechanical components, and includes an oil discharge tube and a refinement tube nozzle connected to the front end of the main body. An air pressure source is connected to the main body. A flow diverter switch is installed on the main body that divides the air pressure source into two streams. One air pressure flows into the main body to drive a piston chamber to pressurize and squeeze out the grease, while the other air pressure flows through a flexible tube into the refinement tube nozzle. Through the reduction in hole diameter to accelerate air flow, and under the dual action of pressurizing the piston chamber and accelerating the refinement of grease through air flow, the grease gun can smoothly and uniformly spray out refined grease.
