Pumping Device With Switching Valve For Safe Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumping devices lack a security mechanism to prevent improper operation, and they do not ensure safe and clean operation when pumping fluids.
Innovation Solution
The pumping device incorporates a switching valve with a valve stem and connecting grooves to control the flow between the barrel and top cover, along with check valves and a delivery unit to manage air pressure and fluid flow safely, allowing users to deflate or inflate the chamber securely and keep it clean by controlling air pressure and fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pumping device is operated directly by a user controlling the operation unit, then the device can pump fluid, but the device lacks security mechanism to prevent improper operation
Solution Approach 1:
The patent introduces a switching valve that must be operated in advance to establish proper fluid pathways before the piston can function. This preliminary action ensures that the receiving chamber is properly sealed and connected to the delivery unit, preventing improper operation and enhancing safety without significantly complicating the overall structure.
Solution Approach 2:
The switching valve acts as an intermediary component between the user's operation and the fluid pumping action. It mediates the fluid flow paths, ensuring that pressure is properly managed and that the piston operates only when correct pathways are established, thereby improving reliability while maintaining operational simplicity.
2Productivity
If the receiving chamber is used to pump liquid, then fluid can be transported, but the chamber may contain impurities and require cleaning
Solution Approach 1:
The patent incorporates a drain hole in the top cover that allows for the extraction of remaining liquid and impurities from the receiving chamber after pumping operations. This extraction mechanism enables easy cleaning and maintenance without requiring disassembly of the chamber, thus maintaining productivity while reducing maintenance difficulty.
3Ease of operation
If air pressure is not controlled in the receiving chamber, then the device is simpler to operate, but the chamber cannot be properly deflated or inflated for safe operation
Solution Approach 1:
The switching valve merges multiple functions into a single component: it controls the connection between the receiving chamber and the delivery unit, manages air pressure by enabling deflation/inflation cycles, and ensures proper sealing. This integration maintains ease of operation by requiring only one valve operation while providing comprehensive security mechanisms for reliable and safe pumping device operation.
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
The device operates more safely and efficiently by allowing users to control air pressure within the chamber, ensuring the chamber remains clean and free of impurities, with the ability to monitor air pressure and release excess pressure when necessary.
Implementation Method 1
a switching valve mounted on the top cover to control connection between the barrel and the top cover
Implementation Method 2
the liquid in the receiving chamber of the barrel is compressed gradually by the air pressure
Implementation Method 3
a plurality of check valves mounted on the piston
Implementation Method 4
a piston movably mounted in the cylinder, and an operation unit mounted on the top cover and connected with the piston to move the piston relative to the cylinder

AI summary
A pumping device includes a barrel (1), a top cover (2), a switching valve (3), a cylinder (4), a piston (53), a connecting unit (6), an operation unit (5), a delivery unit (7), a pressure gauge (8), and a pressure release unit (9). Thus, the user has to pull or push the switching valve to extract or suck the air in the barrel so as to deflate or inflate the barrel so that the pumping device has a security process and is operated in a safer manner. In addition, the flow of the fluid is proceeded in the barrel so that the pumping device is operated smoothly and conveniently.
