Air blowing device, self-suction tail plug, and air blower using the tail plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air blowers suffer from incomplete dust ejection due to the lack of a one-way valve structure in the air outlet nozzle, leading to reduced cleaning effectiveness, and are prone to tilting and instability due to their design, making them difficult to use and place.
Innovation Solution
The air blowing device incorporates an integrated air inlet and outlet device with independent ventilation pipelines and one-way valves, and a self-suction tail plug with a suction cup for stable placement, ensuring unidirectional air flow and preventing back suction, while the tail plug body is designed to securely attach to surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air outlet nozzle does not have a one-way valve structure, then the device structure is simple, but the air will be sucked in again after being sprayed out, causing incomplete dust ejection and weakened cleaning effect
Solution Approach 1:
The air outlet system is segmented into two separate one-way valves: an air inlet one-way valve and an air outlet one-way valve. This segmentation allows independent control of air intake and air discharge, ensuring that sprayed air cannot be sucked back in, thus completing dust ejection while maintaining manageable structural complexity
Solution Approach 2:
The air outlet one-way valve acts as an intermediary component between the air bag and the external environment. It mediates the air flow direction, allowing air to exit the air bag but preventing external air from being sucked back in, thereby ensuring complete dust ejection without requiring complex multi-component valve assemblies
2Weight of moving object
If the air blower is light in weight with a wide body and narrow tail, then the device is portable and easy to handle, but it is very easy to tilt and fall when placed on a desktop, causing great trouble in placement and use
Solution Approach 1:
A suction cup is added to the narrow tail of the air blower, providing a counterbalancing adhesive force that counteracts the toppling moment caused by the device's top-heavy configuration. This allows the lightweight device to remain stable during placement without adding significant weight to the overall structure
Solution Approach 2:
The stability problem is solved by transitioning from a purely gravitational stabilization approach to one that utilizes adhesion forces in a different dimensional context. The suction cup creates a vacuum bond with the placement surface, providing stability through atmospheric pressure rather than solely relying on weight distribution and center of gravity
