Dual-Mode Pneumatic Tool With Switchable Blow and Suction Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tools cannot provide integrated dust blowing and article taking functions, requiring operators to use separate tools for these tasks, which is inconvenient.
Innovation Solution
A pneumatic tool with a main body, air passages, a flow way, and a control mechanism that allows switching between sucking and blowing modes by controlling the air exhaustion passage, enabling both dust blowing and article taking functions with a single tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate tools are used for dust blowing and article taking, then each tool can be optimized for its specific function, but the operator needs to use multiple tools which reduces operational efficiency and convenience
Solution Approach 1:
The patent combines the dust blowing function and article taking function into a single pneumatic tool. The tool includes a main body with an air passage, a flow way, and a control mechanism that enables both blowing and sucking modes, eliminating the need for operators to use separate tools for these functions.
Solution Approach 2:
The pneumatic tool is designed to perform multiple functions: it can blow dust through the flow way and suck/take articles through the same flow way by controlling the air exhaustion passage. This multi-functional design allows a single tool to replace multiple specialized tools, improving operational efficiency.
2Productivity
If a single tool integrates both blowing and sucking functions, then operational efficiency improves, but the internal structure becomes more complex
Solution Approach 1:
The pneumatic tool's internal structure is segmented into distinct functional components: an air passage for air intake, a flow way for dual-purpose airflow control, and an air exhaustion passage for air discharge. The control mechanism is further segmented into open and close positions that independently manage the air exhaustion passage. This segmentation allows complex functions to be achieved through modular, manageable 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
The pneumatic tool allows operators to conveniently switch between dust blowing and article taking modes without needing to replace tools, enhancing operational efficiency and safety by integrating both functions into a single device.
Implementation Method 1
an air passage disposed in the main body, whereby an air source can flow into the air passage to form a fast airflow
Implementation Method 2
When the air exhaustion passage is in the free state, the air in the tool is exhausted from the air exhaustion passage, and the air in the flow way flows toward the air exhaustion passage, a sucking effect is achieved
Implementation Method 3
When the air exhaustion passage is blocked, the air is exhausted from the outer end of the flow way, a blowing effect is achieved

AI summary
A pneumatic tool includes: a main body; an air passage disposed in the main body for air to flow in; an air exhaustion passage disposed in the main body, one end of the air exhaustion passage communicating with the air passage, the other end of the air exhaustion passage being an air exhaustion end; a flow way disposed in the main body, a rear end of the flow way communicating with the air passage, a front end of the flow way being positioned at one end of the main body; and a control mechanism disposed in the main body and connected with the air exhaustion passage. The pneumatic tool provides both blowing and sucking effects. An operator need not replace the tool. Instead, the operator can use the pneumatic tool to blow dust or take an article.
