Inseparable Nozzle Barrel for Consistent Spray Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray guns often have center air orifices defined by moving components, which can lead to inconsistent atomization of liquids due to relative movement during assembly, use, or servicing, affecting the uniformity and consistency of the spray pattern.
Innovation Solution
A barrel with an inseparable nozzle that defines both the center air and liquid-emitting orifices, where the nozzle is integrated or inseparably attached to the main body, ensuring consistent and uniform atomization by fixed surfaces that do not move relative to each other, enhancing the atomization process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the center air orifice is defined by moving components, then the spray gun can be assembled and serviced with separate parts, but the atomization consistency deteriorates due to relative movement between components
Solution Approach 1:
The patent merges the nozzle and barrel into a single unitary component, eliminating the separate nozzle assembly step and ensuring that the center air orifice maintains fixed geometric relationships with liquid-emitting orifices. This integration resolves the contradiction by combining the benefits of ease of operation with improved atomization consistency, as the inseparable design prevents relative movement while maintaining serviceability of the overall spray gun system.
2Ease of operation
If the nozzle is separable from the barrel, then assembly and disassembly is easier, but the risk of damage during assembly or servicing increases
Solution Approach 1:
By integrating the nozzle into the barrel as a unitary component, the patent eliminates the interface between separate parts that could fail during assembly or disassembly. The inseparable design removes the risk of misalignment, dropped components, or damage to threading and sealing surfaces, while the overall spray gun remains serviceable through replacement of the entire barrel assembly.
3Ease of manufacture
If the nozzle and barrel are separate components, then manufacturing and assembly is simpler, but the uniformity of spray pattern deteriorates
Solution Approach 1:
The unitary construction of the nozzle and barrel ensures that the geometric relationships between the center air orifice and liquid-emitting orifices are precisely maintained during manufacturing. By forming these components as a single piece, the patent eliminates cumulative tolerances that would arise from assembling multiple parts, thereby achieving superior spray pattern uniformity while using standard manufacturing processes for the integrated component.

Function Achieved in This Case
This design ensures consistent and uniform atomization of liquids, improving the quality and reliability of the spray pattern by maintaining the integrity of the center air flow and nozzle structure, reducing damage risks during assembly or servicing.
Implementation Method 1
to emit so-called center air from one or more center air orifices, which center air may assist in atomizing the liquid into a spray of small droplets
Implementation Method 2
to emit so-called fan air from one or more fan air orifices, which fan air may assist in both shaping the spray of atomized liquid droplets into a desired pattern and may further assist in atomizing the liquid

AI summary
A barrel for use with a liquid spray gun platform to provide a liquid spray gun comprises a main body and an inseparable nozzle. The main body comprises at least one center air delivery passage and at least one liquid-handling passage. The inseparable nozzle defines a liquid-emitting orifice that is in fluid communication with the at least on liquid-handling passage of the main body, and defines a center air orifice that is in fluid communication with the at least on center air delivery passage of the main body.
