Air purifier with automatic working mode switching function and purification method of air purifier

Abstract

The invention discloses an air purifier with an automatic working mode switching function and a purification method of the air purifier, which belong to the technical field of environmental protection. The air purifier comprises a purifier body, an automatic working mode switching device, a purifying air duct, a dust purifying component, a toxic and harmful gas purifying component, a carbon dioxide purifying component and a detection and control device, wherein the automatic working mode switching device comprises a power input component, a transmission component, a dust purifying drive component and a carbon dioxide purifying drive component. An automatic working mode switching method of the air purifier comprises the steps that a controller of the detection and control device sends a control command according to the condition and change of the current indoor air quality, the corresponding working mode is automatically selected and switched, and indoor air is subjected to dedusting, filtering, purifying, toxic and harmful gas absorption purifying treatment and carbon dioxide absorption purifying treatment respectively. The air purifier always operates at high efficiency and with low energy consumption to reach an effect of efficient and energy-saving operation.

Description

technical field [0001] The invention relates to an environmental protection device and method, in particular to an air purifier with automatic switching of working modes and a purification method thereof. Background technique [0002] Air purifiers are usually composed of air filters, negative ion generators, fans and other systems. During operation, the fans in the body circulate the indoor air, and the polluted air passes through the air filters in the body to remove or absorb various pollutants. Then, through the negative ion generator installed at the air outlet, the air is continuously ionized to generate a large number of negative ions, which are sent out by the fan to form a negative ion airflow to achieve the purpose of purifying the air. [0003] At present, most air purifiers at home and abroad use a fixed multi-layer filter to purify indoor air. In the purification process, the indoor air quality and its changes are not considered, but the purpose of purifying th...

AI Technical Summary

Problems solved by technology

Its defect is: when the air purifier is working, each filter layer is always in working condition, and different working modes cannot be selected according to the changes in the indoor air dust concentration, germ concentration, toxic and harmful gas concentration, etc. When filtering, the filter layer will increase the ventilation resistance, which will inevitably lead to unreasonable use and waste of resources

However, different working modes can only be selected manually, and automatic switching cannot be realized, so it is impossible to make the air purifier always operate with high efficiency and low energy consumption.
