Solution Overview

Problem

Existing atomizers have a complex structure due to the use of a fan for blowing air to an air outlet tube and an air pump for increasing pressure in the water tank, leading to a large size and inconvenience in use.

Innovation Solution

An atomizer design that incorporates a fan to blow air into a water outlet tube, where part of the airflow increases pressure in the water tank, allowing liquid to be sprayed efficiently without the need for a separate air pump, featuring a simplified structure with a control switch and regulating mechanism to adjust the outlet flow rate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fan and air pump are used to blow air to the air outlet tube and increase pressure in the water tank, then the atomizer can spray liquid effectively, but the structure becomes complex and the size increases

Engineering Contradiction:

Improvespraying efficiencyVSAvoidstructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the air blowing function and water pressurization function into a single fan component. The fan blows air into the water outlet tube, and part of this airflow enters the water tank through the pressurizing tube to increase water pressure, eliminating the need for a separate air pump and reducing structural complexity while maintaining effective spraying

AI summary

An atomizer is provided. When the atomizer provided by the invention is used, a fan blows air to a water outlet tube, part of the airflow in the water outlet tube passes through a pressurizing tube to enter a water tank to gradually increase the air pressure in the water tank, and liquid in the water tank is pressed into a water inlet tube under high pressure, flows into a guide tube along the water inlet tube and is sprayed out of the guide tube in a direction away from the fan; after flowing out of the guide tube, the liquid is blown out by the airflow blown from the fan into the water outlet tube on the periphery of the guide tube; and the fan is used for blowing air to the water outlet tube and increasing the pressure in the water tank.
