Abstract
Description
Technical Field
[0001] This utility model relates to a connecting pipe assembly with a dust sensing device. Background Technology
[0002] Existing connecting tube assemblies typically connect one end to the vacuum cleaner main unit and the other end to the vacuum cleaner floor brush. However, to detect the degree of dirt on the floor, a dust sensor is often installed inside the vacuum cleaner floor brush. A similar technology can be found in Chinese Invention Publication Patent CN106725104A. However, because the vacuum cleaner floor brush is closer to the dirty floor, it is easy for dust to accumulate, leading to distortion in the dust sensing. Moreover, once the dust sensor has been used for a long time, it cannot be quickly replaced or repaired. Therefore, improvements are needed. Utility Model Content
