Problems solved by technology

After the filter layer has been working for a period of time, the purification effect will decrease due to pollution, and it needs to be replaced and cleaned. The existing technology does not effectively monitor the pollution degree of the filter layer, and prompts the user when the purification effect becomes poor.

Embodiment Construction

[0007] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0008] In the figure, KQ1 and KQ2 are two air quality sensors, which are installed on both sides of the air inlet and outlet of the filter layer G of the air purifier respectively, and are used to detect the air quality before and after the filter layer G, and the air pollution is high. The output values ​​of the air sensors KQ1 and KQ2 are also high. The air quality values ​​detected by the two sensors are sent to the two input terminals of the operation circuit L, and the operation circuit L judges the pollution degree of the filter layer according to the two air quality values.

[0009] When the purification effect of the filter layer is normal, the air quality at the outlet end of the filter layer will be significantly better than the air quality at the intake end, that is, the difference between the two air quality values ​​will be greater than a certain set ...

Abstract

The invention relates to a method for real-time monitoring the pollution level of a filter layer of an air purification machine, comprising a detection method of air quality. The method is characterized in that air quality sensors are arranged at the air inlet end and the air outlet end of the filter layer and used for detecting the air quality at the two sides of the filter layer; and an operation circuit judges the pollution level of the filter layer according to air quality signals detected by the two air quality sensors. When the filter layer is severely polluted so that the purification effect is poor, an alarm signal can be sent out to remind a user of timely changing or washing the filter layer, thereby ensuring the use effect of the air purification machine.

Description

technical field [0001] The invention relates to the technology of an air purifier in the field of household appliances. Background technique [0002] The air purifier includes a fan and a filter layer. The filter layer can adopt one or more of physical, chemical, biological and other filtration methods. The fan allows the air to pass through the filter layer, and the filter layer realizes the purpose of filtration and purification. After working for a period of time, the filter layer will be degraded due to the pollution and purification effect, so it needs to be replaced and cleaned. The existing technology does not effectively monitor the pollution degree of the filter layer, and prompts the user when the purification effect becomes poor. Contents of the invention [0003] The purpose of the invention is to disclose a method capable of monitoring the pollution degree of the filter layer in real time. [0004] The invention includes a detection method of air quality, whi...
