At present, formaldehyde, toluene, xylene and the like in the decoration of new houses seriously pollute the health of people. The main method of solving indoor air pollution at present is ventilation and air purification equipment, but along with the improvement of people's standard of living, the continuous increase of car quantity, air pollution is more and more serious, and outdoor air pollution degree is generally higher, adopts the ventilation can not be fine solution indoor pollution problem can bring new pollution problem for indoor on the contrary. The existing air purification equipment mainly sucks air into the purifier for purification, and filters particulate matters and microorganisms through a filter screen, or purifies the air in a mode of adsorbing gaseous pollutants and microorganisms through activated carbon.
The purification of air by means of filters or activated carbon mainly has the following drawbacks: 1) the air is pumped into a machine for purification, the pumping range is limited, and the air cannot reach all corners, and particularly, the removal of formaldehyde and germs is not enough; 2) only partially filtering away germs, not disinfecting and sterilizing, and not really removing or killing gaseous pollutants and microorganisms; 3) the activated carbon adsorption mode is used for treating formaldehyde, and because the activated carbon adsorption saturation is greatly influenced by environmental factors (such as space size, space volatile gas quantity, activated carbon quality, activated carbon placing time, placing position and the like), the activated carbon adsorption saturation cannot be judged simply by how many days, whether the activated carbon is actually adsorbed and saturated or not can not be known, and the purification result cannot be ensured.
In addition, the existing air purification equipment is mainly manually controlled to be opened and closed through a switch, so that problems still exist in the use of the equipment, for example, people are sensitive to whether the air has peculiar smell, and when odorless and tasteless harmful gas (such as radon) exists in the air or the content of the harmful gas in the air is not enough to be checked by human smell, people usually cannot open the purification equipment; moreover, differences in indoor decoration materials, living habits of indoor people and external environments cause differences in indoor air quality, so that an instructive starting strategy for the air disinfection purifier cannot be provided, and if the air disinfection purifier is started all day long, the use cost is undoubtedly high.

In other embodiments, the running time of the ozone/oxygen preparation module may be controlled by a preset rule, specifically, the working time of the ozone/oxygen preparation module is calculated by using the detected ozone concentration value, the detected ozone concentration threshold, the detected indoor volume and the detected ozone emission as original data, and when the running time of the ozone/oxygen preparation module reaches the calculated working time, the ozone/oxygen preparation module is turned off, and the indoor volume prompts the user to select before the ozone/oxygen preparation module is turned on.
And step S40, when the pure oxygen gas discharge time is equal to the preset time, closing the ozone-oxygen preparation module.
And after the indoor formaldehyde is completely decomposed by the ozone and is reduced to a preset formaldehyde concentration threshold value, the ozone decomposition tank starts to work to release pure oxygen, and after the pure oxygen is discharged for a period of time, the ozone generator, the second electromagnetic valve and the exhaust fan are closed. In this embodiment, the preset time is selected to be 5 minutes, so that on one hand, the oxygen content of the indoor air is increased to reduce the ozone content, and on the other hand, the odor left after the indoor air is disinfected after the formaldehyde is removed can be eliminated, so that the air is fresher and more pleasant.
