Solution Overview
Problem
Current air purifiers produce ozone as a byproduct during ultraviolet sterilization, leading to secondary air pollution, and there is a need for improved air purification systems that can effectively sterilize and disinfect air while minimizing ozone production.
Innovation Solution
An air sterilization device with a heating apparatus that uses ultraviolet sterilization followed by heating the air to at least 56°C to inactivate viruses and decompose ozone, incorporating a heating system to eliminate ozone and enhance purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet sterilization apparatus is used to sterilize and disinfect air, then sterilization and disinfection effect is improved, but ozone is produced causing secondary air pollution
Solution Approach 1:
The patent applies the principle of converting harm into benefit by using the heating system to transform the harmful ozone produced during ultraviolet sterilization into beneficial oxygen. The heating apparatus heats the air to high temperatures (above 56°C, preferably above 60°C) which causes the ozone to decompose into oxygen, thereby eliminating the secondary pollution while maintaining the sterilization benefits.
Solution Approach 2:
The patent changes the temperature parameter of the air by introducing a heating system that raises the air temperature to at least 56°C (preferably above 60°C). This parameter change serves dual purposes: it inactivates viruses through thermal effect and simultaneously decomposes the ozone produced during ultraviolet sterilization into oxygen, resolving the contradiction between sterilization effectiveness and ozone pollution.
2Reliability
If heating system is added to heat air to inactivate viruses and decompose ozone, then air purification effect is improved, but device complexity increases
Solution Approach 1:
The heating system in the patent serves multiple functions simultaneously: it heats the air to inactivate viruses (thermal sterilization), decomposes ozone into oxygen (pollution elimination), and enhances the overall air purification effect. By making the heating apparatus multi-functional, the patent improves air purification reliability without proportionally increasing device complexity, as one component addresses multiple problems.

AI summary
The air sterilization device with heating apparatus comprises a mainframe, a sterilization system, a heating system, circuits and a control system and a housing. The sterilization system includes an ultraviolet sterilization apparatus to sterilize and disinfect air; the heating system heats the air to inactivate virus; and the housing has an air inlet and an air outlet. Air can circulate into the housing through the air inlet with the action of mainframe and then the air is discharged from the air outlet into a room after the disinfection and sterilization processes are finished. The device with heating apparatus aims at the secondary inactivation of viruses by high temperature after the sterilization and disinfection processes are finished by ultraviolet sterilization apparatus and heating system, and at the decomposition of ozone produced in the process of ultraviolet disinfection to eliminate secondary air pollution by ozone.
