Multi-purpose sprayer with rotatable valve and venturi mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprayers lack the ability to separately dispense multiple liquid products or mix them efficiently, requiring multiple sprayers for different tasks and leading to frequent re-fills and complex valve systems.
Innovation Solution
A multi-purpose sprayer design featuring a chamber assembly with rotatable conduits and a manual actuator for selecting the flow of a first liquid product or a mixture, utilizing a venturi effect for efficient mixing, and including a siphon hose for introducing a second liquid product into the first conduit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional sprayers use fixed purpose nozzles for specific container use, then the nozzle structure is simple, but the sprayer cannot dispense multiple liquid products or mix them
Solution Approach 1:
The patent employs a rotatable valve assembly with conduits that can be rotated to different positions to selectively connect different liquid product containers to the nozzle. This dynamic reconfiguration allows a single nozzle structure to serve multiple functions by changing its internal flow paths through rotation, thereby achieving versatility without requiring multiple fixed nozzles for different products
Solution Approach 2:
The nozzle assembly is designed as a universal component that can handle multiple liquid products through a single structure. The rotatable valve with multiple conduit positions enables the same nozzle to dispense different liquids or mixtures by simply rotating to the appropriate position, eliminating the need for separate specialized nozzles for each product type
2Adaptability or versatility
If sprayers provide mixing capability for multiple products, then the sprayer becomes multi-purpose, but complex control valves and additional operative parts are required
Solution Approach 1:
The patent combines the valve body, multiple conduits, and mixing chamber into a single integrated rotatable valve assembly. This merged structure performs both flow control and mixing functions through one component rather than requiring separate valves and mixing devices, reducing overall system complexity while maintaining multi-product capability
Solution Approach 2:
The rotatable valve assembly dynamically reconfigures internal flow paths by rotation to achieve different mixing ratios or to connect different product containers. This dynamic mechanism replaces complex multi-position control valves with a simpler rotational actuation system that achieves the same functional outcomes
3Productivity
If conventional sprayers lack effective valve systems, then the structure is simple, but frequent re-fills are required
Solution Approach 1:
The rotatable valve assembly provides dynamic flow control that enables efficient product delivery and mixing, allowing users to maintain larger quantities of liquid products in the system for longer periods. By enabling proper mixing and selective dispensing, the system reduces the need for frequent re-fills compared to simple non-mixing sprayers
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 efficient and flexible dispensing of multiple liquid products, reducing the need for multiple sprayers and simplifying the mixing process, while maintaining durability and ease of use.
Implementation Method 1
the flow of water through the sprayer interior creates a venturi effect in the sprayer that draws the product contained in the product container into the flow of water where it is mixed with the water
Implementation Method 2
A back region being formed at an acute angle to the constricted first region; A back region of the second conduit being connected to at least one siphon hose having first and second openings

AI summary
An improved multi-purpose sprayer for separately dispensing a first liquid product and a mixture with a spray head body is presented. The multi-purpose sprayer is operable by manually operating an actuator in a first flow position for selecting the flow of a first liquid product and a second flow position for selecting the flow of the first liquid product and the mixture.
