Bottle Cap Airflow Sealing for Vehicle Air Compressors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted air compressors face issues with tire sealant flowing into the air compressor main body, leading to operational failures, which complicates manufacturing and assembly due to the need for additional parts in the bottle cap assembly to prevent this flow.
Innovation Solution
A bottle cap assembly with an integrally formed sealing and flow guiding component that includes a sealing portion and flow guiding portion, preventing tire sealant from entering the air compressor main body by guiding airflow through the cap assembly without additional parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional parts are added to the bottle cap assembly to prevent tire sealant from flowing to the air compressor main body, then the reliability of the air compressor is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the sealing function and flow guiding function into a single integrated sealing and flow guiding component. This component includes a sealing portion that prevents tire sealant from flowing into the air compressor main body, and a flow guiding portion that directs airflow through the bottle cap assembly. By merging these two functions into one component, the patent reduces the number of parts while maintaining the reliability of preventing sealant contamination.
Solution Approach 2:
The sealing and flow guiding component performs multiple functions simultaneously: it seals the interface between the bottle cap assembly and the air compressor main body, guides the airflow from the air compressor through the tire sealant holding bottle, and prevents tire sealant from flowing back into the air compressor. This multi-functional design eliminates the need for separate sealing components and flow guiding components.

3Ease of manufacture
If a simple bottle cap assembly structure is used, then the ease of manufacture is improved, but the reliability of preventing tire sealant flow deteriorates
Solution Approach 1:
The sealing and flow guiding component performs multiple functions simultaneously: it seals the interface between the bottle cap assembly and the air compressor main body, guides the airflow from the air compressor through the tire sealant holding bottle, and prevents tire sealant from flowing back into the air compressor. This multi-functional design eliminates the need for separate sealing components and flow guiding components.
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
Prevents tire sealant from flowing into the air compressor main body, simplifying the manufacturing and assembly process by integrating the flow guiding function into the sealing component, ensuring smooth airflow while maintaining effective tire repair and inflation.
Implementation Method 1
The sealing portion surrounds the flow guiding portion
Implementation Method 2
high-pressure airflow from the air compressor main body passes through the bottle cap assembly and enters the tire sealant holding bottle, and then the high-pressure airflow drives the tire sealant in the tire sealant holding bottle to enter the tire

AI summary
A vehicle-mounted air compressor includes an air compressor main body and a bottle cap assembly including bottle cap and sealing and flow guiding components. The bottle cap component is at the air compressor main body, has air inlet/outlet openings, and connected to the air compressor main body via the air inlet opening. The sealing and flow guiding component is at the bottle cap component and includes sealing and flow guiding portions, the former surrounding the latter, and the latter covering the air inlet opening and having at least one air inlet hole and an air outlet hole and connected to the air inlet opening via the air inlet hole and connected to the air outlet opening via the air outlet hole. An airflow from the air compressor main body passes through the air inlet opening, the air inlet hole, the air outlet hole, and the air outlet opening in sequence.
