Description

Technical Field

[0001] The present invention relates to the technical field of cleaning of vehicle engines, and in particular to an air filter cleaning machine used in large automobile repair shops, engineering machinery, large mining vehicle equipment, urban construction machinery and the like. Background Art

[0002] The engine is the heart of the car, and the air filter is the lungs of the engine. The cleanliness of the air filter of the car engine has a great relationship with the working power of the vehicle. If there is too much dust in the air filter and it is not cleaned, it will cause insufficient air intake of the engine, insufficient oxygen for combustion, and produce black smoke, which will waste fuel and cause incomplete combustion of the engine. The black smoke produced will seriously pollute the air.

[0003] Mechanical drivers sometimes need to maintain their own equipment, including the air filter of engineering vehicles, which needs to be maintained and cleaned of dust to protect the intake pressure of the vehicle's engine and improve work efficiency. Generally, mechanical vehicles will have precautions to remind mechanical drivers to replace the filter in time. When the air filter alarm shows abnormality, the mechanical driver needs to clean or replace the air filter in time, otherwise it will cause oil leakage and wear of the four matching parts. After cleaning the air filter, the car's air intake will be significantly increased, the exhaust gas and black smoke will be less, oxygen will burn more fully, and carbon deposits will be less, which will increase power. The more dust there is in the car's air filter, the less air intake the engine has and the lower its efficiency. If it is not cleaned in time, it will seriously cause the turbocharger to wear and drain the oil, causing the engine to lock the piston due to insufficient oil and pull the cylinder. Most drivers of construction machinery are busy and are more likely to ignore or do not want to clean this component. Most of all construction machinery work in harsh environments with more wetlands and dust, which will cause the air filter to be more likely to produce garbage. However, mechanical drivers are busy and do less cleaning and maintenance. The few who clean the air filter usually take out the air filter and hold it with their hands, and use a compressed air pipe to remove dust from the surface and inside. Doing so will first cause dust to float all over the sky, which is bad for the surrounding air. Then, when the air pipe pressure is too high, it will cause danger to people. Finally, when cleaning the air filter, dust will be generated on the surface of the cleaning personnel's body, which is difficult to clean. When cleaning, dust will fly everywhere. Too much dust enters the atmosphere, and some dust will float on the driver's clothes, causing damage to the environment.

[0004] There are still many deficiencies and defects in the existing vehicle air filter cleaning methods. The drivers of various types of construction machinery have high workloads, and because they do not understand mechanical engines, they rarely have basic maintenance knowledge and do not understand construction machinery. As a result, the air filters cannot be maintained and cleaned for a long time, causing pollution. Summary of the invention
