Air purification system and method based on air pressure sensing

Abstract

The invention discloses an air purification system and method based on air pressure sensing. The system comprises an air purifier, an air pressure sensing device and a background terminal, wherein the air pressure sensing device detects indoor and outdoor air pressure and transmits the indoor and outdoor air pressure to the air purifier through a network, the air purifier compares the indoor and outdoor air pressure, and transmits the comparison result to the background terminal through a network, and the background terminal sends a control command to the general air purifier according to the comparison result, and controls the air purifier to open and operate. The air pressure sensing device comprises an indoor air pressure sensor and an outdoor air pressure sensor. The system performs indoor and outdoor air pressure detection through the air pressure sensing device, compares the indoor and outdoor air pressure through the air purifier, transmits the control command to the air purifier according to the comparison result, controls operation of the air purifier and adjusts the indoor pressure, and outdoor unpurified air is prevented from directly entering a room due to atmospheric pressure and affecting the cleanliness of indoor air.

Description

technical field [0001] The invention relates to the field of household air purification, in particular to an air purification system and an air purification method based on air pressure induction. Background technique [0002] With the deteriorating environment, especially the problem of air pollution has attracted more and more people's attention, especially in our country, the air pollution is particularly serious, and PM2.5 is seriously exceeded. Very adverse health effects. Therefore, people have become more and more concerned about how to purify the air, and various air purifiers have emerged as the times require. Air purifiers refer to household appliances that have a certain ability to remove solid pollutants (such as dust, pollen, bacteria-carrying particles, etc.) and gaseous pollutants (odor, formaldehyde and other decoration pollution, etc.) in indoor air. As people began to pay attention to air quality and gas pollution after decoration, air purifiers began to ...

AI Technical Summary

Problems solved by technology

[0003] Existing air purifiers mainly use the adsorption purification mode to purify the indoor air through non-stop work, but when using range hoods or exhaust fans, the indoor air will be discharged to the outside, making the indoor pressure lower than Outdoor pressure, under the action of atmospheric pressure, the outdoor unpurified air will directly enter the room, causing the short-term pollution index of the indoor air to rise, but it is inevitable to use exhaust fans and range hoods in the family. While using range hoods and exhaust fans, effectively ensuring the cleanliness of indoor air is a problem that needs to be solved at this stage
