Abstract

The invention relates to a formaldehyde detection method. The method comprises the following steps of acquiring a first detection value provided by a first sensor, wherein the first sensor is used fordetecting the formaldehyde content in air; acquiring a second detection value provided by a second sensor, wherein the second sensor is used for detecting the non-formaldehyde interference gas content in the air; and judging a threshold interval where the second detection value is located, and obtaining a formaldehyde detection result according to the threshold interval, the second detection value and the first detection value. According to the threshold interval, the second detection value and the first detection value, the formaldehyde detection result is obtained, so that the detection result is more accurate and the problem that detection is inaccurate due to the fact that the first detection value is directly adopted as the formaldehyde detection result is effectively avoided. The invention further relates to a formaldehyde detection device and an air purifier.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a formaldehyde detection method, device and air purifier. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, people pay more and more attention to the quality of the surrounding environment, especially in newly renovated homes, the formaldehyde index is used as an important condition to measure whether it is livable, and it is usually used before living Formaldehyde testing will be performed. [0003] At present, there are various formaldehyde detection devices on the market, but the inventor has found through extensive research and experiments that most of the household formaldehyde detection devices on the market are easily interfered by alcohol, perfume and other gases, causing the detection value to deviate from the accurate value , although some existing formaldehyde detection devices also comp...
