Summary: | The novel air purifier based on the infrared particulate matter sensor comprises an air purification circulating air duct and an air quality detection circulating air duct which are arranged independently, and the air purification circulating air duct is sequentially provided with a first air inlet, a purification assembly, a first fan system and a first air outlet. And a second air inlet, an infrared particulate matter sensor, a second fan system and a second air outlet are sequentially arranged on the air quality detection circulating air duct. By arranging the air purification circulating air duct and the air quality detection circulating air duct which are independent of each other, the problem that the detection value of the infrared particle sensor is changed due to the change of the running state of the air purifier is effectively solved, so that the detection channel of the infrared particle sensor has stable air flow speed; detection values are more accurate, stability is high, and service life is lo |
