Spray Gun Connection Adapter for Mixing, Suction, and Mist Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning devices require frequent and laborious operation due to the inability to efficiently mix and spray gas and liquid simultaneously, often resulting in excessive mist formation, and existing solutions complicate the process with multiple nozzle configurations that are inconvenient to switch between functions.
Innovation Solution
A spray-gun apparatus with a rotary structure and connection adapter featuring separate gas output and suction paths, allowing for efficient gas-liquid mixing and dust suction, and enabling quick function changes without disassembling the nozzle cover-bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-flow gas is mixed with liquid and sprayed out, then cleaning capability is improved, but large amount of mist-like water drops are generated causing inconvenience
Solution Approach 1:
The spray nozzle is divided into multiple spray holes arranged in different directions. Each spray hole sprays liquid in a specific direction rather than mixing gas and liquid together, which prevents mist formation while maintaining cleaning capability through multi-directional liquid coverage.
Solution Approach 2:
The gas flow path and liquid spray paths are completely separated. Gas enters through one path while liquid is sprayed through separate holes, extracting the harmful mixing effect while preserving the beneficial cleaning functions of both gas and liquid.
2Adaptability or versatility
If nozzle cover-body with gas-pumping hole is used, then dust suction capability is improved, but operator must repeatedly dismantle and mount different nozzle cover-bodies
Solution Approach 1:
The single nozzle cover-body integrates both spray functions and dust suction function. The spray holes can spray liquid for cleaning, while the gas-pumping hole enables dust suction capability, making one component perform multiple functions and eliminating the need to switch between different nozzle cover-bodies.
Solution Approach 2:
The spray holes and gas-pumping hole are combined in the same nozzle cover-body structure. This merging of functions allows the operator to use a single unified component for both liquid spraying and dust suction operations, improving ease of operation.
3Device complexity
If conventional sprayer is used, then结构简单 (structure is simple), but frequent laborious pressing is required
Solution Approach 1:
The spray nozzle maintains continuous liquid spraying capability without requiring repeated pressing actions. The water storage bucket and pump system enable continuous operation, eliminating the need for frequent manual intervention while maintaining structural simplicity.
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 apparatus reduces operator inconvenience by allowing efficient gas-liquid mixing and dust suction, eliminating the need for frequent disassembly and enabling seamless switching between gas-pumping and non-gas-pumping functions.
Implementation Method 1
the liquid is sucked by the flow tube through the pressure difference caused by the high-flow gas
Implementation Method 2
A high-flow gas is sprayed from the gas flow tube to the spoiler tube
Implementation Method 3
the second conduction tube of the connection adapter is used to connect a gas suction apparatus, so that the gas around the second conduction tube can be sucked into through the second conduction tube of the connection adapter
