Description

Air conditioning duct cleaning system

The invention relates to an air conditioning duct cleaning system, in particular to a technician who can adjust the position of the cleaning surface according to the size of the inner wall of the duct.

According to the conventional air conditioning duct, the air duct can be divided into a rectangular duct and a circular duct. Generally speaking, in the case of the same air supply volume, since the circumference of the circular duct is smaller than that of the rectangular duct, although the friction loss and the heat loss of the circular duct are small, the rectangular duct is easier to be attached to the ceiling of the building. The shape fits, therefore, the rectangular duct is the mainstream product of the current central air-conditioning installation. In addition, since the inner wall of the air duct is more likely to be contaminated with some dust bacteria under the long-term air supply, the inside of the air duct must be cleaned at intervals, so as to avoid the harm caused by the human body contaminated with dust. The situation arises.

According to the current knowledge, the device inside the air duct can be cleaned, such as the new type 325710 "air-conditioning duct cleaning machine"; the new type 325710 "cleaning joint device for air duct cleaning"; and the new type 494804 "cleaning of air duct" As shown in the patents such as the structure, these patents use the cooperation of the vacuum cleaner and the brush body to clean the inner wall of the air duct.
