Leaf Blower Attachment for Continuous Liquid Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current personal spraying devices for liquids like insecticides and herbicides are limited by the power generated, resulting in a short range and inconsistent spraying capability, making them ineffective for home users, who often cannot afford commercial blowers or rely on professionals for services.
Innovation Solution
A universal blower attachment system that connects a pressurized tank to a standard handheld or backpack leaf blower, using an atomizer to enhance the air stream for increased reach and coverage, allowing continuous spraying with adjustable flow regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If hand pumping or pre-pumping into a pressurized container is used, then the spraying power is generated, but the power is quite limited and the range is limited to a few feet
Solution Approach 1:
The patent combines a pressurized spray container with a powered leaf blower by attaching the spray container to the blower's exhaust stream. The leaf blower's motor generates high-power air flow that merges with the liquid spray, propelling it much farther than hand-pumped systems alone could achieve. This merging of two separate systems (spray container and leaf blower) resolves the contradiction by providing both spraying capability and extended range.
Solution Approach 2:
The patent uses an intermediary attachment mechanism that connects the pressurized spray container to the leaf blower's exhaust system. This intermediary structure allows the spray container to be positioned in the high-velocity air stream of the leaf blower, enabling the air flow to carry the liquid spray farther. The intermediary attachment serves as a mediator that transfers energy from the leaf blower to the spray system.
2Power
If pre-pump spray container is used, then the spraying power is generated, but the pressure quickly drops upon engagement and requires the user to stop after 30 seconds or less to pump again
Solution Approach 1:
The patent enables continuous spraying by utilizing the leaf blower's continuous operation to maintain constant pressure in the spray container. As the leaf blower runs continuously, it continuously draws liquid through the attachment, preventing pressure buildup and eliminating the need for periodic manual pumping. This continuous action resolves the contradiction by allowing uninterrupted spraying for the entire duration of leaf blower operation.
Solution Approach 2:
The system becomes self-regulating through the interaction between the leaf blower and spray container. The leaf blower's exhaust stream continuously draws liquid through the attachment, automatically maintaining pressure equilibrium without requiring user intervention. The system self-manages the pressure dynamics, eliminating the need for manual pumping cycles.
3Ease of manufacture
If personal spraying devices are used, then the cost is reduced, but the spraying capability is inconsistent and the range is short
Solution Approach 1:
The patent creates a universal attachment system that can be attached to any standard leaf blower, making it adaptable to existing equipment rather than requiring a specialized expensive sprayer. The attachment design allows it to work with various leaf blower models, providing consistent spraying capability across different devices while maintaining affordability for home users.
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 system provides high-power and consistent spraying capability, enabling users to effectively apply liquids over larger areas, including hard-to-reach spaces like under leaves and foliage, with improved range and efficiency compared to existing personal sprayers.
Implementation Method 1
The atomizing system comprises an atomizer, liquid tube, pressurized liquid container and a leaf blower. The user will be able to choose different size tank such as a 1 gallon or 2 gallon handheld tank, or backpack 3 to 4 gallon tank. The tanks will be pressurized by a manual or powered pump that will push the liquid through the hose, through the atomizer end of the hose, and will be atomized by the blower.
Data Source
AI summary
The invention is a universal blower attachment that will fit any standard handheld leaf blower or standard backpack blower and a system for atomizing and dispensing insecticides and other liquids, allowing a pressurized tank to continually force liquid through the nozzle for continuous atomization and spraying into the exhaust stream of the leaf blower.
