Sprayer Nozzle Sleeve Segmentation for Cleaning and Flux Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprayers have complex assembly procedures, limited space for adjusting paint flux, and difficulties in cleaning the nozzle, leading to inaccurate paint application and time-consuming adjustments.
Innovation Solution
A sprayer design featuring a removable nozzle sleeve and a conically shaped nozzle with a rotating knob for easy assembly, cleaning, and precise paint flux adjustment, ensuring the nozzle sleeve is fixed in place to prevent misalignment during spraying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nozzle is integrated into the body with a fixed structure, then the spraying structure is stable, but the nozzle is difficult to clean and requires complex assembly procedures
Solution Approach 1:
The nozzle assembly is divided into separate components: the nozzle body, the nozzle sleeve, and the mounting part. The nozzle and nozzle sleeve can be detached from the mounting part, allowing easy removal and cleaning without disassembling the entire sprayer. This segmentation enables independent cleaning of the nozzle components while maintaining a relatively simple overall assembly structure.
2Ease of operation
If the adjusting part is positioned inside the mounting part, then the structure is compact, but the space for adjusting paint flux is limited
Solution Approach 1:
The adjusting part (knob) is repositioned from an internal location within the mounting part to an external location on the outer side of the mounting part. This spatial relocation in another dimension provides sufficient finger access and manipulation space for adjusting the paint flux, while the internal threading structure maintains the compact overall design.
3Ease of operation
If the adjusting part is turned to change paint flux, then the paint flow can be controlled, but the paint outlet may shift position causing spraying errors
Solution Approach 1:
The nozzle assembly is segmented into the nozzle, nozzle sleeve, and mounting part with distinct functions. The nozzle sleeve is fixed in position relative to the mounting part, while the nozzle can be adjusted independently via the knob. This segmentation allows adjustment of paint flux without affecting the positional alignment of the paint outlet, maintaining spraying accuracy.
Solution Approach 2:
The nozzle sleeve acts as an intermediary component between the mounting part and the nozzle. It provides a stable reference frame that prevents the paint outlet from shifting when the adjusting knob is turned, while still allowing the nozzle to be adjusted for paint flux control.
4Ease of manufacture
If the nozzle sleeve is not fixed on the mounting part, then assembly is simpler, but the paint outlet may misalign with the air outlet
Solution Approach 1:
The nozzle sleeve is merged with the mounting part through a fixed connection structure (such as threading or interference fit). This combination ensures that the nozzle sleeve maintains a fixed position relative to the mounting part, preventing misalignment between the paint outlet and air outlet, while still allowing for relatively simple assembly procedures.
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
Facilitates quick and convenient cleaning of the nozzle, provides ample space for accurate paint flux adjustment, and prevents mistakes in paint application by maintaining a fixed nozzle sleeve position, thus saving time and improving overall efficiency.
Implementation Method 1
When the high-pressure gas flows through the air passage 80, the paint in ht paint bottle 87 is guided out by the high-pressure gas and sprayed on an object
Implementation Method 2
The front end of the nozzle (2) has a conic shape. The first paint outlet (200) of the passage (20) is located at the front end of the nozzle (2)

AI summary
A sprayer with an improved spraying structure comprises a body, a nozzle, a knob, and a nozzle sleeve. The body has a passage and a valve. At the end of the passage is an air outlet. A mounting part with an insertion hole is provided around the body. The assembly of the nozzle, the knob, and the nozzle sleeve is inserted in the mounting part. The paint bottle with paint is connected to the knob.
