Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a device for detecting dust accumulation on the inner surface of an air duct of an air conditioner. Background Art

[0002] Air conditioning ventilation ducts are new-type pipes produced in one go by advanced machinery. They are mainly made of metal materials and are mainly used in ventilation systems in the air conditioning industry. During long-term use, air conditioning ducts are prone to blockage due to dust accumulation, which affects the use effect of the air conditioner. Therefore, they need to be detected using a special dust detection device to facilitate timely cleaning.

[0003] There are still some problems with the existing dust detection devices for the surface of air-conditioning ducts. First, some of the existing detection devices use various high-precision infrared detection instruments or measuring instruments to measure the thickness or weight of dust accumulation inside the duct, and obtain the dust accumulation situation for cleaning. Not only is the detection cost high, but it also requires continuous manual detection, and the detection is also relatively inconvenient. Secondly, various detection equipment requires special equipment when collecting and extracting dust. Dust is easily accumulated on the detection equipment, resulting in reduced detection effect, which is not conducive to subsequent use. Utility Model Content
