Solution Overview
Problem
Existing negative ion generating apparatuses using corona discharge produce harmful by-products like ozone and nitrogen oxides, and electrostatic effects, limiting their widespread application and effectiveness in improving air quality and human health.
Innovation Solution
An air negative ion generating apparatus that utilizes a high-pressure gas flow carrying water molecules to collide with a surface, generating negative ions without by-products, using a design with a liquid container, cover body, and core assembly that includes a liquid flow chamber and collision component, creating a high-speed gas-liquid mixture to produce negative ions without additional power or electrostatic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If corona discharge is used to generate negative ions, then negative ion concentration is high and technology is mature, but harmful by-products such as ozone and nitrogen oxides are generated and electrostatic effects occur
Solution Approach 1:
The patent extracts and removes the harmful by-products (ozone and nitrogen oxides) from the negative ion generation process by completely abandoning the corona discharge method. Instead, it uses a mechanical collision method where high-pressure gas carrying water molecules collides with a collision surface to generate negative ions, thereby eliminating the source of harmful substances while maintaining high negative ion concentration.
Solution Approach 2:
The patent changes the fundamental parameter of the generation mechanism from electrical discharge (corona discharge) to mechanical collision (high-pressure gas flow). This parameter change transforms the process from an electrical field-based method that produces harmful by-products to a mechanical field-based method that generates only negative ions and water molecules, resolving the contradiction between ion concentration and harmful emissions.

Implementation Method 1
Under external action such as radiation, ultraviolet light, lightning, physical shock, or corona discharge, some electrons at an outer layer will escape from the nucleus to form free electrons and be further captured by neutral molecules to form negative ions
Implementation Method 2
a high-pressure gas inlet pipe communicated with the liquid flow chamber, a lower end of the high-pressure gas inlet pipe facing the collision component; a liquid flow inlet located between the lower end of the high-pressure gas inlet pipe and the collision component
