Solution Overview
Problem
Conventional atomization cooling equipment has a limited cooling effect due to the upward dissipation of air with reduced temperature and increased specific gravity caused by water vapor, resulting in a less refreshing cooling sensation.
Innovation Solution
The equipment electrifies the atomization water using an induction electrode unit, increasing the adhesion of water particles to human skin through Coulomb force and reducing the upward dissipation of air by repulsive forces between electrified water particles, enhancing the cooling effect and mimicking the Lenard effect at natural waterfalls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional atomization cooling equipment is used to cool space by evaporating finely atomized water, then the temperature of air is reduced by absorbing evaporative latent heat, but the cooled air tends to dissipate upward due to buoyancy of evaporated water vapor and mixing with air, reducing the cooling effect
Solution Approach 1:
The patent replaces the conventional mechanical atomization system with an electrified atomization head that uses electrostatic fields to atomize water. The electrified water particles generate repulsive forces between themselves, preventing aggregation and upward dissipation, thereby stabilizing the cooled air in the target space while maintaining temperature reduction through evaporation.
2Productivity
If conventional atomization cooling equipment is used, then cooling is provided through evaporation of finely atomized water, but the cooling effect is not sufficient due to upward dissipation of cooled air
Solution Approach 1:
The patent employs an electrified atomization head that uses electrostatic fields instead of conventional mechanical atomization. The electrified water particles repel each other, preventing aggregation and upward movement of cooled air, thereby retaining cooling energy in the target space and enhancing the overall cooling effect.
Solution Approach 2:
The patent changes the electrical charge parameter of water particles by applying high voltage to the atomization head. This electrification creates repulsive forces between water particles, preventing them from aggregating and causing upward dissipation of cooled air, thereby improving cooling efficiency and reducing energy loss.
3Ease of operation
If atomization water is electrified, then adhesion to human skin is increased by Coulomb force enhancing cooling sensation, but device complexity increases due to high-voltage generating means
Solution Approach 1:
The patent replaces conventional mechanical atomization with an electrified atomization head that uses electrostatic fields. This substitution not only enhances cooling sensation through increased adhesion of water particles to skin via Coulomb force but also stabilizes the atomized water in the target space, reducing the need for complex control systems.
Solution Approach 2:
The electrified atomization head serves multiple functions: it atomizes water, electrifies the water particles for enhanced skin adhesion and cooling sensation, and prevents upward dissipation of cooled air through repulsive forces. This multi-functionality reduces the need for additional separate systems, thereby mitigating device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The electrification of atomization water increases the adhesion to human skin, enhances the refreshing cooling sensation, and suppresses air dissipation upward, resulting in a higher cooling effect by maintaining a higher specific gravity of atomized-water-mixed air.
Implementation Method 1
an induction electrode unit (44) provided in the atomization head (10) and electrifying the atomization water from the atomization nozzle (38)
Implementation Method 2
when the atomization water from the electrified atomization head is electrified, the amount of adhesion to the human skin is increased by the Coulomb force
Implementation Method 3
since each of the water particles atomized to the space is electrified, repulsive force works between the water particles, the probability that the particles are collided and associated with each other and grow and fall is small
Implementation Method 4
the air of which temperature has been reduced by evaporation of the finely atomized water jetted from the atomization head
Implementation Method 5
when the atomization water from the electrified atomization head is negatively electrified, the state similar to that of the so-called Lenard effect said to be generated at natural waterfalls can be generated

AI summary
Cooling water is pressurized and supplied via a pipe to an electrified atomization head installed in an atomization cooling area A, the jetted particles of the cooling water from the electrified atomization head are electrified and atomized. An electrification voltage is applied from a voltage application unit to the electrified atomization head, and the external electric field generated by applying a voltage between a water-side electrode unit and an induction electrode unit is applied to the cooling water in a jetting process so as to electrify the atomization water and facilitate adsorption to people.
