Bubble Nozzle Air Duct Layout for Compact Fan Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fog bubble machines suffer from poor space utilization and limited fan size and power due to the fan being directly positioned below the nozzle, hindering a compact design.
Innovation Solution
The fan is mounted at the inlet side of the film forming nozzle, with an air duct conveying wind to the outlet side, allowing flexible determination of fan size and power, and utilizing the liquid storage reservoir to stabilize the air duct position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fan is directly disposed below the fog bubble nozzle, then the structure is simple, but the space utilization is poor and the fan size and power are limited
Solution Approach 1:
The patent repositions the fan from a vertical arrangement (directly below the nozzle) to a horizontal arrangement (at the inlet side of the nozzle), utilizing the lateral space within the housing. This dimensional change allows the fan to be larger and more powerful while maintaining compact overall dimensions, thereby improving space utilization without significantly increasing structural complexity
2Device complexity
If the fan is directly disposed below the fog bubble nozzle, then the structure is simple, but the fan size and power are limited
Solution Approach 1:
By moving the fan to the inlet side horizontally, the patent enables installation of a larger fan with greater power output. The air duct system then channels this increased airflow to the outlet side, allowing the machine to generate more bubbles or operate at higher power levels without compromising structural simplicity
3Area of stationary object
If the fan is repositioned to improve space utilization, then space utilization improves, but the air duct configuration becomes more complex
Solution Approach 1:
The air duct serves as an intermediary component that connects the fan at the inlet side to the outlet side. This mediator allows the fan to be positioned optimally for space utilization while still delivering airflow to the required location, managing the complexity through a dedicated flow path rather than direct coupling

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances space utilization and allows for adjustable fan size and power, improving the overall compactness and efficiency of the bubble machine.
Implementation Method 1
a fan (400) mounted on the same side of the liquid storage reservoir (200) and the film forming nozzle (500), wherein the fan (400) and the film forming nozzle (500) are staggered in a height direction (D1)

AI summary
A bubble machine includes a liquid storage reservoir, a film forming nozzle, film scraping body, and driving device. The liquid storage reservoir is configured to store bubble liquid. The film forming nozzle defines a bubble liquid channel. The film scraping body is mounted near an outlet side of the film forming nozzle and is capable of moving to pass the outlet side of the film forming nozzle. The driving device is configured to drive the film scraping body to move and drive the bubble liquid in the liquid storage reservoir to be conveyed to the bubble liquid channel of the film forming nozzle.
