Description

Technical Field

[0002] Dust detector is called dust monitor for short. It is also called dust measuring instrument or dust tester. It is mainly used to detect the dust concentration in the ambient air. The types of dust monitors are divided into: laser dust monitor, online continuous monitoring dust monitor, portable dust monitor, etc.

[0003] Current environmental dust detectors, such as the environmental dust detector proposed in authorization announcement number: CN220231380U, use a motor to drive the rotation of a rotating ring. Four detection sensors are set on the ring, but the detection sensors are only used for detection when they are rotated to the bottom. The others are used for standby and fan cleaning. Only when the cleaned detection sensors are rotated to the bottom in the next step, the detection results will be more accurate.

[0004] Although the existing environmental dust detector is equipped with a cleaning structure to clean the surface of the detector when in use, not only will the dust on the surface of the environmental dust detector cause errors in detection, but when the environmental dust detector is working, air containing dust will flow through the inside of the detector, causing dust to adhere to the internal pipes of the detector. The existing environmental dust detector needs to be disassembled to clean the internal dust, which is inconvenient to use. Utility Model Content
