A non-contact microplasma ozonized mist radical sterilizer is designed with a high-concentration oxygen generator, ozone decomposer, microplasma ozone generator, air volume control, air circulation pump, and mist generator, which generates ozone at low temperature, decomposes residual ozone into oxygen, and collects mist for final sterilization, utilizing OH radicals for effective air and surface sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low-temperature microplasma is used to generate ozone for sterilization, then sterilization effectiveness is improved, but residual ozone remains that requires additional processing
Solution Approach 1:
The patent converts the harmful residual ozone into beneficial oxygen through a catalyst-containing filter. The filter captures ozone and transforms it into oxygen through catalytic decomposition, turning a harmful byproduct into a useful substance that enhances the sterilization process while ensuring safety.
Solution Approach 2:
The patent introduces a catalyst-containing filter as an intermediary component between the ozone generation and the environment. This filter acts as a mediator that decomposes ozone into oxygen, allowing the system to benefit from ozone's sterilization properties while eliminating its harmful residual effects.
2Reliability
If chemical disinfectants are used for sterilization, then sterilization is achieved, but environmental pollution and health concerns arise
Solution Approach 1:
The patent replaces chemical disinfectants with a physical-chemical process involving low-temperature microplasma and catalytic decomposition. Instead of using harmful chemical agents, the system uses plasma-generated ozone followed by catalytic conversion to oxygen, achieving sterilization through physical and chemical transformations rather than chemical disinfection.
Solution Approach 2:
The patent changes the fundamental parameter of sterilization from chemical-based to plasma-based. By using low-temperature microplasma to generate ozone and then converting it to oxygen through catalysis, the system achieves sterilization through controlled physical-chemical parameter changes rather than chemical disinfectant application.
3Reliability
If a complete sterilization system with ozone generation and decomposition is implemented, then sterilization stability is improved, but device complexity increases
Solution Approach 1:
The patent merges the ozone generation and decomposition functions into an integrated system where the catalyst-containing filter serves dual purposes: it filters particles and simultaneously decomposes ozone into oxygen. This merging of functions reduces the need for separate components and simplifies the overall system structure while maintaining sterilization stability.
Solution Approach 2:
The catalyst-containing filter is designed with multi-functionality, serving both as a particle filter and an ozone decomposition device. This universal component performs multiple functions within a single element, reducing system complexity while ensuring stable and complete sterilization through coordinated ozone generation and decomposition.

AI summary
The present invention relates to a non-contact microplasma ozonized mist radical sterilizer. The present invention minimizes two discharge spaces to a micro size to lower a breakdown voltage, concentrates electromagnetic fields using micro-patterns to induce micro-discharge at a normal pressure, and generates plasma through glow discharge, to increase electron density and reduce power consumption according to generation of microplasma. When oxygen and air are injected as reaction gases using this principle, ozone is generated as active species, and the generated ozone is used for various purposes such as removing pests, reducing ethylene, and sterilizing harmful bacteria. Sterilization is improved by sterilizing air and generating mist using ozone generated from microplasma, and then decomposition and drying of ozone gas are performed using a heat generation device and a catalytic method.
