Abstract

The invention discloses a control method of a dust concentration detection component for a dust collector. The dust concentration detection component comprises a main body, a light transmitting device, a light receiving device and a transparent vibrator. The control method comprises the following steps: controlling the transparent vibrator to start to work so as to remove accumulated dust on lenses of both the light transmitting device and the light receiving device; detecting the intensity of light received by the light receiving device; when the intensity of light received by the light receiving device is smaller than the lower limit of a preset intensity interval, controlling the light transmitting device to improve the intensity of transmitted light to enable the intensity of light received by the light receiving device to be in the preset intensity interval. The control method can control the dust concentration detection component to perform self-cleaning during dust concentration detection at each time, so that the dust concentration detection precision can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a control method for a dust concentration detection component of a vacuum cleaner. Background technique [0002] At present, vacuum cleaners such as sweeping robots generally use a side-to-side shooting method to detect dust concentration, for example, a side-to-side infrared shooting method can be used for detection. However, when using this method to detect dust concentration, if there is a backlog of dust at the transmitting end or receiving end, the detection accuracy will be greatly reduced, which will cause misjudgment, and the detection range is small, and it cannot detect all dust in the air duct of the vacuum cleaner. Space dust concentration is detected. [0003] Therefore, the current dust concentration detection technology of sweeping robots needs to be improved. Contents of the invention [0004] The purpose of the present invention is to ...
