Abstract

Disclosed in the present application are a filter screen cleanliness detection method, a filter screen cleanliness sensor and an air treatment apparatus. The filter screen cleanliness sensor comprises a first light emission assembly and a first light reception assembly, the first light emission assembly and the first light reception assembly are provided at a same side of an installation position of a filter screen, the first light emission assembly is configured to emit first detection light, and the first light reception assembly is configured to receive the first detection light reflected by the filter screen. The filter screen cleanliness detection method comprises the following steps: controlling the first light emission assembly to emit the first detection light, and acquiring a first optical intensity signal received by the first light reception assembly; comparing the intensity of the first optical intensity signal and a first preset intensity; when the intensity of the first optical intensity signal is less than the first preset intensity, determining that the filter screen is in a un-installed state; and when the intensity of the first optical intensity signal is greater than or equal to the first preset intensity, determining that the filter screen is in an installed state.

Description

technical field [0001] The invention relates to the field of sensor technology, in particular to a method for detecting the cleanliness of a filter screen, a filter screen cleanliness sensor, and air processing equipment. Background technique [0002] In the air treatment equipment, there is usually a filter screen, on the one hand, it can prevent impurities in the indoor air from entering the air treatment equipment and cause equipment failure, and on the other hand, it can also improve the quality of the indoor air. As the use time increases, dust, germs, etc. will adhere to the filter, so it is necessary to test the cleanliness of the filter. The sensor used to detect the cleanliness of the filter includes a light-emitting component and a light-receiving component, which are respectively installed on both sides of the filter. When dust, germs, etc. are attached to the filter, the light intensity received by the light-receiving component will change. This reflects changes...
