Description

Technical Field

[0002] Generally speaking, due to mining operations in many mines, there will be dust in the air under the mines, so dust detection devices will be used. However, many dust detection devices adopt the suction type, which sucks the air into the dust detection device to detect the dust content in the air. Therefore, many suction-type dust detection devices are provided with air intake holes at the suction end. However, after long-term use, dust will adhere to the wall of the hole. Since many suction-type dust detection devices are not convenient for cleaning the inner wall of the hole, when the air dust content is detected again, the dust attached to the hole wall will also be sucked into the detection end of the detection device, which will affect the detection of the air dust content by the detection device, thereby reducing the accuracy of the detection.
