Inner wall cleaning device for car exhaust pipe

Abstract

The invention discloses an inner wall cleaning device for a car exhaust pipe. The inner wall cleaning device comprises a base, and one side of the top of the base is connected with a dust collector and an air pump through bolts. The other side of the top of the base is connected with a box through bolts, and the inlet end of the dust collector is connected with a dust suction pipe through a clamping hoop. The other end of the dust suction pipe is connected with a mounting sleeve through a bolt, and the other end of the mounting sleeve is connected with a hollow shaft type stepping motor through a bolt. According to the inner wall cleaning device, blown off deposited dust is sucked into the dust collector by the dust suction pipe from the dust suction opening, and the inner wall cleaning work of the car exhaust pipe is completed. The cleared deposited dust can be prevented from staying in the exhaust pipe, and the cleaning effect is improved. When the stepping motor enters the car exhaust pipe, a roller on a protection sleeve is in rolling connection with the inner wall of the exhaust pipe, damage of the stepping motor and exhaust pipe caused by collisions is avoided, and the stability of the device is improved.

Description

Technical field [0001] The invention relates to the technical field of automobiles, and in particular to an inner wall cleaning device for automobile exhaust pipes. Background technique [0002] Automobile exhaust pipe is a part of automobile engine exhaust system. The exhaust system mainly includes exhaust manifold, exhaust pipe and muffler. Generally, three-stage catalytic converters that control pollutant emissions from automobile engines are also installed in the exhaust system. The exhaust pipe generally includes a front exhaust pipe and a rear exhaust pipe. During the driving of the car, a lot of dust will adhere to the inner wall of the car exhaust pipe, causing the exhaust pipe to be poorly exhausted and the exhaust pipe to corrode. The phenomenon. [0003] During car maintenance, when the maintenance personnel clean the exhaust pipe of the car, they simply use the rod to hold the rag to wipe back and forth, and cannot remove the dust attached to the inner wall.

Generally, the three-stage catalytic converter that controls the emission of pollutants from the automobile engine is also installed in the exhaust system. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe. During the driving process of the car, a lot of dust will adhere to the inner wall of the exhaust pipe of the car, resulting in poor exhaust and corrosion of the exhaust pipe. The phenomenon

[0003] During car maintenance, when cleaning the exhaust pipe of the car, the maintenance personnel simply use the rod-shaped object to hold the rag to wipe back and forth, which cannot remove the dust attached to the inner wall. The inside of the exhaust pipe, resulting in unsatisfactory cleaning effect
