Switchable Air Gun Nozzle for Dust-Free Suction Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air guns lack the ability to switch to a sucking mode, making them ineffective in environments where only air suction is necessary for cleaning, and they often worsen air quality by dispersing dust when used for cleaning, posing health risks.
Innovation Solution
An air gun with an airflow switching and controlling element inside the gun tube allows for directional airflow control, enabling both ejection and suction functions, reducing dust dispersion and enhancing airflow pressure for efficient cleaning while minimizing energy consumption and operational costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional air guns eject high pressure airflow for cleaning, then cleaning function is provided, but dust flies around and air quality deteriorates
Solution Approach 1:
The air gun is designed with a switching mechanism that enables it to perform both ejection and suction functions. The airflow direction control element allows the single device to adapt to different work requirements, making it universal for both blowing and sucking operations, thereby eliminating the need for separate vacuum cleaners in suction-only scenarios.
Solution Approach 2:
The invention introduces a switching mechanism that can reverse the airflow direction. By inverting the airflow direction from outward ejection to inward suction, the device effectively captures dust instead of dispersing it, thus resolving the harmful effect of dust flying around while maintaining the cleaning function.
2Adaptability or versatility
If conventional air guns are used in environments where only air suction is necessary, then the device cannot meet work requirements, but adding suction function increases device complexity
Solution Approach 1:
The air gun incorporates an airflow direction control element that enables it to switch between ejection and suction modes. This multi-functionality allows the device to adapt to various work environments, including those where only suction is required, without needing separate specialized equipment for each function.
Solution Approach 2:
The invention uses a dynamic switching mechanism that can change the airflow direction based on operational needs. The switching element allows the device to transition between different functional states (ejection mode and suction mode), providing adaptability to different work requirements while maintaining a relatively simple overall structure.
3Productivity
If high pressure airflow is ejected for cleaning, then cleaning effectiveness is improved, but energy consumption and operational load increase
Solution Approach 1:
The invention introduces a switching mechanism that can reverse the airflow direction. By inverting the airflow direction from outward ejection to inward suction, the device effectively captures dust instead of dispersing it, thus resolving the harmful effect of dust flying around while maintaining the cleaning function.
Solution Approach 2:
The invention utilizes the air compressor's operational parameters (pressure and flow rate) more efficiently by switching between ejection and suction modes. This allows the system to operate at optimal points on the compressor's performance curve, reducing unnecessary energy consumption while maintaining effective cleaning performance.
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 air gun effectively prevents dust dispersion, improves air quality, and reduces energy consumption and operational costs by allowing for efficient airflow management between ejection and suction modes.
Implementation Method 1
an airflow switching and controlling element being a tube body sleeved inside the large diameter tube of the gun body for moving forward and backward inside the large diameter tube to guide an airflow to eject through the small diameter tube and to guide the airflow to form a sucking airflow in a rear end of the gun tube
Implementation Method 2
the outer conical surface at the front end of the small diameter section and an inner end of the small diameter tube correspondingly form a circular opening for ejecting airflow to force the airflow inside the small rebound pressing space for ejecting airflow to compress through the circular opening for ejecting airflow for forming the airflow ejection with an enhanced pressure
Implementation Method 3
The design inside the gun body can cause the airflow to eject with a higher pressure for drawing the air in the back to move forward

AI summary
An air gun with sucking function comprises a gun body, an air intake control set and an airflow switching and controlling element. The air gun with sucking function of the present invention employs the airflow switching and controlling element disposed inside the gun tube of the gun body for switching an airflow flowing direction and converting an airflow ejection into a sucking airflow in order to meet various work requirements by switching to different functions. When it is switched for sucking airflow for cleaning, dust can be prevented from flying around and therefore is healthier for breathing.
