Lever-Guided Inflator Valve Connector for Air Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflator valve connectors experience air leakage when connecting or disconnecting air valves, leading to incomplete inflation and inability to achieve precise desired pressure.
Innovation Solution
The inflator valve connector features a body with a guiding hole, a rotatable guiding member, and a lever. The guiding member moves between positions to control air flow, and the lever actsuates this movement to prevent air leakage during connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the valve connector connects or disconnects the air valve, then the inflation operation can be performed, but air leakage occurs during connection and disconnection
Solution Approach 1:
The sealing ring is pre-positioned on the valve connector body to seal the air valve periphery before inflation begins. The guiding member is pre-configured to guide the spindle into the correct position that simultaneously seals the valve core and maintains peripheral sealing, preventing air leakage during connection and disconnection operations.
Solution Approach 2:
The guiding member acts as an intermediary component between the spindle and the air valve. It controls the movement and positioning of the spindle, ensuring that the spindle depresses the valve core properly while the sealing ring maintains contact with the air valve periphery, thus preventing air leakage during operation.
2Productivity
If the spindle depresses the valve core to open the valve, then air can flow to inflate the object, but air escapes from the valve stem when disconnecting
Solution Approach 1:
The sealing ring is pre-positioned to seal the air valve periphery before the spindle depresses the valve core. This preliminary sealing action ensures that when the spindle is retracted during disconnection, air cannot escape from the valve stem because the peripheral seal is already in place.
Solution Approach 2:
The valve connector is segmented into distinct functional components: the sealing ring for peripheral sealing, the guiding member for controlled movement, and the spindle for valve core depression. This segmentation allows each component to perform its specific function independently, ensuring that the sealing function is maintained while the valve opening/closing operation occurs.
3Reliability
If the sealing ring seals the air valve periphery, then air leakage is prevented, but the desired pressure precision cannot be achieved due to earlier leakage
Solution Approach 1:
The sealing ring establishes a reliable seal on the air valve periphery before the inflation process begins. By pre-sealing the periphery, the system prevents any air leakage that would otherwise occur during connection or disconnection, ensuring that the pressure measurement accurately reflects the true pressure inside the inflated object without being compromised by leakage losses.

AI summary
An inflator valve connector includes a body, a guiding member and a lever. The body has a connecting end, an operating end and a guiding hole. The guiding member is rotatably and movably inserted through the guiding hole and is movable relative to the guiding hole between a first position and a second position. The guiding member has a pushing end, an inlet end and an air passage extending from the pushing end to the inlet end and communicating with the guiding hole. The lever is pivotally mounted to the operating end to selectively abut against the guiding member in a unlock position and a lock position, and the lever is configured to actuate the guiding member to move relative to the guiding hole.
