Solution Overview

Problem

Existing air ionizers are power intensive and lack space efficiency, making them less effective for purification, ventilation, and HVAC applications.

Innovation Solution

The ion generator features a high voltage source, a central body with a primary conductive line, and multiple arms with emitter arrays and secondary conductive lines. The arms are distributed helically, spirally, and symmetrically around the central axis, maximizing airflow and ionization efficiency.

Solution Approach 1:

The ion emitter is divided into multiple discrete needles arranged in arrays on radial arms, allowing distributed ionization across multiple zones. This segmentation enables the system to achieve high total ion output through multiple efficient emitters rather than one large power-intensive emitter, directly resolving the contradiction between power efficiency and ion output productivity.

Solution Approach 1:

The ion emitters are arranged in three-dimensional space with radial arms extending from a central body, creating a volumetric ionization pattern. This multi-dimensional spatial arrangement maximizes ion output within a compact footprint, resolving the contradiction between space efficiency and ion production productivity.

Solution Approach 1:

The radial arm structure serves multiple functions simultaneously: it provides mechanical support for emitter arrays, establishes the helical/spiral spatial distribution pattern, and defines the compact geometric configuration. This multi-functionality reduces overall device complexity while maintaining high ion output productivity through multiple emitters.

AI summary

An ion generator (100) includes a high voltage source (102), a body (104) defining a central axis (A), and multiple arms (106) extending from the body. The body has a primary conductive line (108) electrically coupled to the high voltage source, and a first insulating covering (110) surrounding the primary conductive line. Each arm has an emitter array (116) and a secondary conductive line (112). The emitter array is disposed at a distal end (120) of the arm relative to the body. The secondary conductive line is electrically coupled to the primary conductive line at a proximal end of the arm relative to the body and extends to the emitter array. The arms are distributed about the central axis, such that the orientations of the emitter arrays and the connection of each arm to the central body are distributed helically, spirally, or symmetrically with respect to other arms, relative to the central axis.
