Air disinfection purifier and its control method, device and storage medium for removing formaldehyde

Abstract

The invention discloses an air sterilizing purifier and a formaldehyde removal control method, a device and a storage medium thereof. The control method comprises the following steps of obtaining first data which are detected by a formaldehyde sensor and include indoor air formaldehyde concentration, comparing the first data with a preset formaldehyde concentration threshold value and sending a prompt of starting a formaldehyde removal work mode if the first data is larger than the preset formaldehyde concentration threshold; after receiving an instruction of operating the formaldehyde removal work mode, starting and controlling ozone oxygen preparation module to generate ozone / oxygen mixed gas which is emitted indoors; obtaining second data including indoor air formaldehyde concentration, comparing the second data with the preset formaldehyde concentration threshold value and controlling the ozone oxygen preparation module to generate pure oxygen gas which is emitted indoors when the second data is smaller than the preset formaldehyde concentration threshold value; shutting down the ozone oxygen preparation module when the pure oxygen gas emission time is equal to the preset time. The control method has the advantages of visuality and timeliness.

Description

technical field [0001] The invention relates to the technical field of indoor air purification, in particular to an air disinfection purifier and its control method for removing formaldehyde, a control device, and a computer-readable storage medium. Background technique [0002] At present, decoration pollution such as formaldehyde, toluene and xylene in new house decoration seriously endanger people's health. At present, the main solution to indoor air pollution is ventilation and air purification equipment. However, with the improvement of people's living standards and the continuous increase in the number of cars, air pollution is becoming more and more serious. The degree of outdoor air pollution is generally high, and ventilation is not very effective. A good solution to the indoor pollution problem will bring new pollution problems indoors. The existing air purification equipment mainly sucks the air into the purifier for purification, and filters out particulate matt...

Problems solved by technology

[0003] Purifying air through filters or activated carbon mainly has the following defects: 1) the air is pumped into the machine for purification, the extraction range is limited, and it cannot reach every corner, especially the removal of formaldehyde and germs is not enough; 2) it can only partially Filtering out germs, can not be sterilized, and does not remove or kill gaseous pollutants and microorganisms in the true sense; 3) Activated carbon adsorption method to treat formaldehyde, because the adsorption saturation of activated carbon is affected by environmental factors (space size, space volatile gas The amount of activated carbon, the quantity of activated carbon, the quality of activated carbon, the time of placing activated carbon, the location of placement, etc.) have a great influence, and the saturation cannot be simply judged by the number of days. It is impossible to know whether the activated carbon is actually adsorbed and saturated, and the purification result cannot be guaranteed

[0004] In addition, the existing air purification equipment is mainly controlled by a switch to open and close manually, so there are still some problems in the use of these equipment, such as people are more sensitive to the presence of peculiar smell in the air, when there is odorless and tasteless harmful gas in the air (such as radon), or when the content of harmful gases in the air is not enough for people's sense of smell to detect, people often do not turn on the purification equipment; All will lead to differences in indoor air quality. Therefore, it is impossible to give a guiding strategy for starting the air disinfection purifier, and if it is turned on all day, the cost of use will undoubtedly be high.

The existing intelligent air purification equipment is equipped with sensors and other devices to monitor the air quality, but the control method is complicated and cannot optimize the indoor air quality such as the oxygen bar mode, making the room fresh and pleasant
