Drip Hose With Segmented Flow Path And Pressure Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common hoses on the market experience excessive liquid discharge speed, leading to inconvenient use and content waste due to rapid flow, often resulting in jetting water.
Innovation Solution
A drip hose design featuring a reverse tapered small liquid outlet hole with a circular arc chamfer, a strip groove on the sealing ring, and a buckling mechanism between the hose body and inner plug, which creates a storage space and slows down liquid flow through different-sized apertures, allowing for a drip effect and reduced waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a common hose with a small outlet is used, then the liquid discharge speed is high, but this causes jetting water phenomenon and content waste
Solution Approach 1:
The liquid discharge path is segmented into two distinct stages: first through the small liquid outlet aperture in the sealing ring, then through the larger small liquid outlet hole in the drip head inner plug. This segmentation creates a controlled flow path that prevents direct high-speed discharge while enabling gradual liquid release, solving the contradiction between discharge speed and content waste.
Solution Approach 2:
The storage space formed by the sealing post, sealing ring, and hollow inner cavity acts as an intermediary chamber between the liquid source and the final discharge point. This intermediary space buffers the liquid flow, allowing pressure equalization and controlled discharge through the small liquid outlet hole, thereby preventing jetting water phenomenon and reducing content waste.
2Ease of operation
If the liquid flows directly out of the small outlet under large pressure, then the discharge is fast, but it causes jetting water and inconvenience
Solution Approach 1:
The storage space created by the sealing post, sealing ring, and hollow inner cavity serves as a cushioning chamber that absorbs and equalizes pressure before liquid discharge. This beforehand cushioning prevents sudden pressure surges from causing jetting water, making the hose easier to control and more convenient to use while maintaining appropriate discharge speed.
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 drip hose achieves a controlled, slow liquid discharge, preventing waste and enhancing user convenience by buffering the outflow, ensuring the content is used efficiently and hygienically.
Implementation Method 1
the small liquid outlet hole has a reverse tapered shape. the small liquid outlet hole with reverse tapered shape has a circular arc chamfer near the head of the drip head inner plug
Implementation Method 2
the sealing post of the hose body, the sealing ring of the drip head inner plug and the hollow inner cavity of the drip head inner plug jointly form the storage space
Implementation Method 3
the aperture size of the small liquid outlet hole is larger than the aperture size of the small liquid outlet aperture
