When the air purifier works, the air suction pump 13 is started, air to be purified is sucked into the filtering cavity in the shell 7 through the pipe orifice at the upper end of the air inlet pipe 6, the air entering the filtering cavity travels in the filtering cavity from top to bottom, firstly passes through the ozone generator 14 to carry out ozone sterilization on bacteria and viruses in the air, the air after ozone sterilization contains a large amount of ozone, and although the ozone can be used for disinfection and sterilization, the ozone per se can be used for disinfection and sterilizationHas strong oxidizing property and pungent smell, and continuously inhales ozone which is not good for human health, and the ozone-containing air after ozone disinfection and sterilization needs to be analyzed and decomposed, so the scheme is that an ozone analyzer 16 is arranged below an ozone generator 14, and the ozone analyzer 16 is filled with an active enzyme catalyst, specifically Mn02Catalyst, or Mn02And MnCOaThe catalyst of the present invention may be a paper-like manganese-containing ozonolysis catalyst or a polymer-supported partial oxide ozonolysis catalyst, as long as it can decompose and resolve ozone in the air into oxygen, and it is noted that the active enzyme catalyst filled in the ozone analyzer 16 needs to be replaced after a certain period of use.
In the disinfection space of entering sterilamp 15 downwards along with the trend of the air after ozone analyzer 16 decomposes the analysis, it has two effects to set up sterilamp 15 in ozone analyzer 16's below, and sterilamp 15 can be on the one hand to the bacterium in the air and virus kill once more, and during the epidemic situation of respiratory disease epidemic, for example during new crown epidemic situation, set up the scheme of this twice air disinfection of ozone and ultraviolet ray, can be to the more thorough of virus kill in the air. On the other hand, the ultraviolet rays generated from the ultraviolet germicidal lamp can be used to decompose the ozone which is not completely decomposed and remains after the decomposition by the ozonizer 16, that is, the remaining ozone can be used to decompose the ozone again by irradiation with ultraviolet rays, and the triatomic ozone 0 is excited by the ultraviolet rays3Oxygen 0 capable of being converted into two atoms2。
The air after the ultraviolet germicidal lamp 15 handles gets into active carbon filter equipment 17 downwards, it also has two effects to set up active carbon filter equipment 17 in the below of ultraviolet germicidal lamp 15, the active carbon that sets up in the active carbon filter equipment 17 on the one hand can adsorb the filtration to the particulate impurity etc. of air, and inhale smell and the net smell to the peculiar smell in the air, increase the purification cleanliness factor of air, active carbon filter equipment 17 itself is a better air purification and odour removal device, simultaneously the active carbon can also be to after ozone analyzer 16, ultraviolet germicidal lamp 15 analysis handles, the low concentration ozone that probably still remains in the air decomposes the analysis once more, active carbon filler in the active carbon filter equipment 17 can also decompose and analyze low concentration ozone, in order to thoroughly realize the complete decomposition of remaining ozone.
The air treated by the activated carbon filter 17 enters downward into the lower part of the filter chamber and contacts with the ozone concentration detection sensor 23 provided therein, and the ozone concentration detection sensor 23 mainly detects whether the air decomposed and analyzed three times by the ozonizer 16, the ultraviolet germicidal lamp 15, and the activated carbon filter 17 contains ozone of high concentration or not, and transmits the detection value to the controller 27. When the detected value is no ozone residue or low ozone content, which meets the standard, the controller 27 does not perform any treatment, the air sterilizing and purifying device performs air purifying operation normally according to the set program, when the ozone content in the air is higher and does not meet the standard, the controller 27 controls the electric push rod 25 to ascend, thereby pushing up the choke plate 24 to rotate upwards around its connecting hinge until the choke plate 24 is pushed to the level, closing the lower part of the filtering chamber, so that the air in the filtering chamber can not be discharged downwards, and can be continuously remained in the filtering chamber to make decomposition, filtration and purification, until the detection value of ozone analyzer 16 is up to standard, the controller 27 can control electric push rod 25 to make it downwards move, the choke plate 24 rotates downwards around its connecting hinge, opening the passage below the recovery filter chamber, pushed by the triple forces of gravity, the extension spring 26 and the thrust of the suction pump 13. If the continuous detection value of the ozone concentration detection sensor 23 in three minutes is not qualified or the detection is frequently unqualified, if the number of times of the detection is unqualified in one hour exceeds 5 times, the controller 27 controls a warning lamp and a buzzer of the air sterilization and purification equipment to give a warning to remind a user to replace the active enzyme catalyst filled in the ozone analyzer 16.
