The timer can be used to control the intelligent air purifier to connect to the power supply within a set time, and the air quality monitoring module can be used to monitor the comprehensive air pollution index at all times to determine whether the intelligent air purifier is connected to the power supply. This is more intelligent and environmentally friendly, and the user does not need to judge whether to turn on or off the intelligent air purifier.

[0065] The filter selection unit determines whether to use the first filter 512 and the second filter 513, or to use the first filter 512 and the second filter 513 at the same time. Selectively using different filters can extend the service life of the filters, which is more economical and environmentally friendly. At the same time, when the PM2.5 dust index and the formaldehyde index in the air exceed the preset threshold, a window closing signal is generated, and an alarm prompt is sounded, which can relieve the working pressure of the smart air purifier. At the same time, the doors and windows are closed when the purifier is not turned on, which is more green and healthy.

[0066] In addition, a humidity detection unit is provided to increase the humidity of the air at the same time, making it more convenient and healthier for users to use.

[0067] The size of the interval and threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technical personnel in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.
