In some embodiments, the bottom of the housing may be fitted with several rollers.

An air quality sensor 30 is fixed in the housing 10 near the air inlet and near the air outlet, and the air quality sensor 30 is electrically connected to the main board and is used for monitoring the concentration of substances in the air, such as the concentration value of PM0.3, and displaying the monitored value on a display screen in real time, such as displaying the detected parameter of the virus attachment index of 0.3 micron on the display screen. The air quality sensor 30 at the air inlet is a first air quality sensor 31 and is used for monitoring the quality of air sucked by the air purification and disinfection equipment, namely the quality of air before purification; the air quality sensor 30 at the air outlet is a second air quality sensor 32 for monitoring the quality of the air discharged after being purified by the air purifying and sterilizing apparatus.

And the display screen is fixed on one side surface of the shell 10 and can display various air quality parameters.

The mainboard is fixed in the casing 10, and with display screen, air quality sensor 30 electric connection for the information operation that gathers with air quality sensor 30 is carried out the back output and is shown on the display screen.

The air quality data are read through the air quality sensors 20 at the air inlet and the air outlet, so that the purification effect of indoor air can be more clearly reflected; and the disposable purification efficiency of the air can be calculated by the processor on the mainboard according to two data of the air quality before purification and the air quality after purification, so that the parameter disposable purification efficiency is displayed on the display screen in real time.

The user can know the running state of the air purification and disinfection equipment through the parameter of the disposable purification efficiency, and when the numerical value of the disposable purification efficiency is obviously reduced, the user is prompted that the ion box 52 in the air purification and disinfection equipment 100 has too much dust collection and needs to be cleaned in time.

The decontamination and disinfection module may include a primary filter screen 51, an ion box 52, a UV (ultra Rays) chamber 53, a blower 54 and a honeycomb filter screen 55. The purifying and disinfecting module 50 can sterilize and disinfect microbes (bacteria and viruses) in the air for many times, and purify chemical pollutants and particulate matters in the air for many times.

In this embodiment, the primary filter screen 51, the ion box 52, the UV chamber 53, the fan 54 and the honeycomb filter screen 55 are fixedly installed in the housing 10, and are sequentially arranged from bottom to top from the air inlet to the air outlet of the housing 10.
