Sprayer With Internal Mixing Chamber Prevents Air Inlet Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprayers for mixed solutions and water often suffer from inefficient liquid flow adjustment, air inlet blockage due to bubble formation, and aesthetically unpleasing designs, particularly in double barrel sprayers where the air inlet is exposed and prone to blockage.
Innovation Solution
A sprayer design featuring a housing with a diversion chamber and distribution channels, a siphon channel, and a spray portion with clear-water and mixture nozzles, allowing for adjustable liquid flow and separation of nozzles to prevent residual bubbles, enabling selective spraying of water or mixed solutions with adjustable concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air inlet is exposed outside the sprayer, then air can be easily introduced for bubble formation, but the exposed air inlet may be blocked by bubbles generated, rendering poor performance
Solution Approach 1:
The air inlet function is extracted from the exposed external position and integrated into the internal chamber structure. The chamber serves as both the mixing container and the air inlet mechanism, eliminating the separate exposed air inlet that was prone to blockage while maintaining the bubble generation capability.
Solution Approach 2:
The air inlet function is merged with the chamber structure itself. The chamber serves multiple functions: containing the liquid mixture, providing the mixing space, and serving as the air inlet for bubble formation. This integration eliminates the separate exposed air inlet component that was susceptible to blockage.
2Productivity
If liquid and water are mixed in a container before spraying, then the mixed solution can be sprayed, but the liquid gradually dilutes with water after each spraying process
Solution Approach 1:
The mixing process is segmented into continuous small-scale mixing within the chamber during spraying, rather than bulk mixing in a separate container. This allows fresh liquid to be continuously added to the chamber and mixed with water in small amounts, maintaining concentration while enabling continuous spraying.
Solution Approach 2:
The liquid is prepared in advance in the container, and the chamber is pre-filled with a small amount of liquid before spraying begins. During spraying, liquid is continuously replenished from the container to the chamber, ensuring consistent concentration is maintained throughout the spraying process.
3Device complexity
If a single nozzle is used for both clear water and mixed solution spraying, then the device is simpler, but the nozzles include clear-water nozzles and the mixture nozzle which are separated from each other
Solution Approach 1:
The chamber structure serves multiple functions: it acts as the mixing container, the air inlet, and the distribution point for both clear water and mixed solution streams. This multi-functionality allows separate nozzle streams to originate from a single integrated structure, providing versatility without proportionally increasing overall device complexity.
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 sprayer effectively mixes and sprays solutions with adjustable concentration, preventing air inlet blockage and offering multiple spray modes, including clear-water and bubble solutions, while maintaining an aesthetically pleasing design.
Implementation Method 1
liquid in the container is delivered to the siphon channel through the liquid pipe due to siphon effect
Implementation Method 2
Water is introduced by the operation portion to generate a negative pressure. Thereby liquid in the container is delivered to the siphon channel

AI summary
A sprayer for mixed solution and water is revealed. The sprayer can be used for cleaning objects, spraying mixed solution for agricultural purposes, and so on. The mixed solution is formed by liquid mixed with water, while the liquid can be fertilizers, pesticides, detergents, and etc. The sprayer can selectively spray out the mixed solution or water only.
