Solution Overview

Problem

Existing atomizers have complex structures, short spray ranges, and are difficult to assemble, affecting their working efficiency.

Innovation Solution

An atomizer design featuring a housing assembly with a fog-generating device and air supply device, where the fog-generating device is partially housed in a mounting cavity and extends towards a fluid outlet, and the air supply device is located upstream, enhancing airflow velocity and pressure to increase spray range and efficiency, while maintaining a simple structure for easy assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the atomizer uses a complex structure with multiple components, then the spray function can be achieved, but the assembly becomes difficult and the structure is hard to manufacture

Engineering Contradiction:
Improveease of assemblyVSAvoidstructure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the air supply device and fog-generating device into a single integrated housing assembly with a unified mounting cavity. The air supply device includes an air supply cavity and the fog-generating device includes a fog-generating cavity, both mounted within the same housing structure, eliminating the need for separate complex assembly steps and reducing overall structural complexity while maintaining spray functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing assembly serves multiple functions simultaneously: it provides structural support, guides airflow, houses the air supply device, and mounts the fog-generating device. This multi-functional design reduces the number of separate components needed, simplifying both manufacturing and assembly processes while achieving the desired spray performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If the atomizer has a short spray range, then the structure can be compact, but the working efficiency is reduced

Engineering Contradiction:
Improveworking efficiencyVSAvoidspray range
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The patent employs an air supply device that generates high-velocity airflow to atomize and propel fog drops. The air supply cavity includes an air outlet that directs airflow toward the fog-generating cavity, creating a pneumatic force that extends the spray range. This pneumatic mechanism enables the atomizer to achieve both compact structure and extended spray range by using air pressure to propel droplets farther than gravitational or kinetic methods alone would allow.

Inventive Principle:
Principle #29Pneumatics and hydraulics
