Description

Technical Field

[0001] The utility model relates to the technical field of automobile air ducts, in particular to a device for cleaning an air duct. Background Art

[0002] Automobile ventilation ducts are pipes used for exhaust ventilation in automobiles. When exhausting the air from inside the automobile, some impurities will be discharged along with the gas. The discharged impurities will be adsorbed on the inner wall of the exhaust ventilation duct, which will cause more impurities to be adsorbed on the inner wall of the automobile ventilation duct after a period of use. If it is not cleaned in time, it will affect the use of the automobile ventilation duct. Currently, the market generally uses a deep brush to brush it off. Usually the brush is integrated and cannot be adjusted. Therefore, it is generally not suitable for pipes of different diameters, which limits the scope of use and reduces practicality.

[0003] For example, a cleaning device for automobile ventilation duct disclosed in a Chinese patent document (Announcement No.: CN219635165U) can clean automobile pipes of different diameters through the mutual cooperation between structures such as a fixed cylinder, a rotating rod, a threaded pipe, a threaded rod, a cleaning brush, a fixed frame, a first bevel gear and a second bevel gear to meet the needs under different conditions, thereby improving the practicality of the device.

[0004] However, there are still the following shortcomings:

[0005] When cleaning the ventilation duct, it is necessary to manually rotate the fixed cylinder to drive it to rotate, so that the inner wall of the ventilation duct can be cleaned with the cleaning brush. Since the cleaning brush needs to be squeezed and contacted with the inner wall of the ventilation duct, the large friction makes manual rotation and cleaning more labor-intensive and the cleaning efficiency is low. In addition, the threaded rod is exposed to the outside. Once the dust and impurities that fall down are absorbed during cleaning, it is easy to cause greater resistance to the subsequent adjustment of the cleaning brush, increase the difficulty of adjustment, and even cause the cleaning brush to get stuck.

[0030] Working principle: Step 1, during adjustment, the handle 6 is driven to drive the rotating rod 5 to rotate clockwise, and the rotation of the rotating rod 5 drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the adjusting sleeve 4 to move downward through the cooperation of the threaded sleeve 2.
