Pivotable Air Intake Tube for Pneumatic Cleaning Gun
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic cleaning guns with rotation mechanisms face challenges in practical assembly and interference during use due to the rigidity of external connecting hoses, which hinders efficient cleaning and user convenience.
Innovation Solution
The pneumatic cleaning gun features a pivotably mounted air intake tube that can be adjusted to various positions, allowing for more practical assembly and reduced interference during cleaning, enhancing user convenience and cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air intake tube is rigidly mounted on the cleaning gun, then the assembly structure is simple, but the suction hose interferes with cleaning work and user convenience is reduced
Solution Approach 1:
The air intake tube is changed from a rigid fixed mounting to a pivotable mounting that allows dynamic adjustment. The tube can rotate relative to the gun body and be positioned at different angles, enabling the suction hose to be oriented away from the cleaning area to eliminate interference while maintaining structural simplicity through a single pivot connection point.
2Adaptability or versatility
If the air intake tube is pivotably mounted to eliminate hose interference, then user convenience is improved, but the assembly structure becomes more complex
Solution Approach 1:
The air intake tube is segmented into a fixed portion attached to the gun body and a movable portion that can pivot independently. This segmentation allows the tube to be adjusted to different positions for adaptability while keeping the pivot mechanism simple and localized to one connection point between the segments.
3Adaptability or versatility
If multiple openings are required for air inlet, liquid inlet, and air intake, then cleaning functionality is enhanced, but the number of external connecting hoses increases making assembly less practical
Solution Approach 1:
The air inlet opening and air intake opening are positioned and oriented such that their required external connecting hoses can be routed through or near the same structural region of the gun body. The pivotable air intake tube allows its hose to be positioned close to the compressed air hose routing, effectively merging the hose management in that area and simplifying assembly despite having multiple functional openings.
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 adjustable air intake tube improves the practicality of assembling external connecting hoses and minimizes disruption during cleaning, ensuring effective dirt removal and user comfort.
Implementation Method 1
an air intake tube which leads into the covered flow channel and can also be connected to a suction device via a suction hose in order to suction dirt particles through the flow channel
Implementation Method 2
uses high-pressure air to suction the liquid in the interior of the liquid container through the liquid removal hose such that the liquid mixes with the high-pressure air and continues through the nozzle to be sprayed out to the exterior

AI summary
A pneumatic cleaning gun according to the present invention comprises a gun housing with a compressed air connection, a liquid nozzle with a nozzle cover, and an air intake tube which leads into the covered flow channel and can also be connected to a suction device via a suction hose in order to suction dirt particles through the flow channel. The cleaning gun is configured such that the air intake tube is not rigidly but pivotably mounted on the cleaning gun. The air intake tube can therefore be mounted in a plurality of different positions of use such that the user can find the most comfortable or convenient position of use and the air intake tube can be correspondingly adjusted.
