The invention relates to an air quality test and
display device of a purifier. The air quality test and
display device of the purifier is characterized by including sensors, a
central processing unit, and a display screen, wherein the sensors collect the
indoor air quality parameters and the sensors include a temperature sensor, a
humidity sensor, a light sensor, a dust sensor and / or a
smoke sensor; the
central processing unit is connected with the sensors, processes signals of the sensors and controls the processed signals; the display screen is connected with the
central processing unit and is provided with a displaying function, and the air quality parameters processed by the central
processing unit such as temperature,
humidity,
dust particles and / or
smoke are displayed on the screen; the air quality test and
display device of the purifier has functions of testing and adjusting the air quality automatically, displays the air-purifying degree and alarms through the display screen at the same time. The air quality test and display device of the purifier has the advantages of being reasonable in structure and convenient to use, capable of greatly improving the intelligentization of the
air purifier, capable of saving energy and protecting environment, and capable of satisfying the humanized practical demands.
