Spray Gun With Detachable Cleaning Joint for Self-Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray guns lack the functionality to clean the passage during use, limiting their applicability.
Innovation Solution
A spray gun design that incorporates a detachable cleaning joint and atomization hood, allowing for alternate use between spraying and cleaning processes, facilitated by a compression nut for quick installation and a T-shaped pipeline for efficient cleaning fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only an atomization hood is arranged at the front end of the gun body, then the spray gun can perform spraying function, but it cannot perform cleaning function during use
Solution Approach 1:
The spray gun is designed with a detachable front end that can be configured with either an atomization hood for spraying or a cleaning joint for cleaning operations. This allows a single spray gun device to perform multiple functions (spraying and cleaning) by simply changing the attached component, thereby improving versatility without significantly increasing overall device complexity
Solution Approach 2:
The front end of the spray gun is segmented into detachable components - specifically, the atomization hood and cleaning joint can be independently attached or removed. This segmentation allows the user to switch between spraying and cleaning functions by detaching one component and attaching another, resolving the contradiction between functionality and structural simplicity
2Adaptability or versatility
If a cleaning joint and straw component are added to enable cleaning function, then the spray gun gains self-cleaning capability, but the device structure becomes more complex
Solution Approach 1:
By integrating both the atomization hood and cleaning joint as optional attachments for the same spray gun body, the design enables the device to perform multiple functions (spraying and self-cleaning) without requiring separate dedicated devices. The cleaning joint with straw component allows high-speed water flow to clean the passage, adding self-cleaning capability while maintaining a relatively simple overall structure through component sharing
Solution Approach 2:
The cleaning joint and straw component are designed to integrate with the existing spray gun body structure, merging the cleaning function into the same device platform. This consolidation allows the spray gun to gain self-cleaning capability without proportionally increasing device complexity, as both functions share common structural elements
3Ease of operation
If detachable components are used for atomization hood and cleaning joint, then installation and replacement become convenient, but additional accessories are required
Solution Approach 1:
The atomization hood and cleaning joint are designed as detachable segments that can be independently attached or removed from the spray gun body. This segmentation enables convenient installation and replacement operations, allowing users to switch between functions by simply detaching one component and attaching another, directly improving ease of operation
Solution Approach 2:
Since both the atomization hood and cleaning joint serve different functions but attach to the same spray gun body, the design reduces the need for multiple separate devices. Users only need to invest in one spray gun platform with interchangeable attachments rather than maintaining separate spraying and cleaning devices, thereby offsetting the accessory requirement through functional consolidation
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
Enables both spraying and self-cleaning capabilities, expanding the gun's functionality and reducing accessory needs while maintaining cost-effectiveness.
Implementation Method 1
the compression nut is in threaded connection with the external thread, and the stop end face fits with the stopper of the limited bulge loop
Implementation Method 2
the cleaning joint or the atomization hood are installed on the spray gun body by a compression nut
Implementation Method 3
the water flowing quickly in the water pipe can flow into the pipeline in the spray gun body by the cleaning joint, then access into the straw component along the pipeline
