Auxiliary device for cleaning automobile air conditioner

Abstract

The invention relates to an auxiliary device for cleaning an automobile air conditioner, which belongs to the related technical fields of vehicle engineering and mechanical engineering. It mainly includes: spray gun and accelerator pedal connecting rod ferrule; one side of the accelerator pedal connecting rod ferrule is fixedly connected with the positioning plate; a screw runs through the positioning plate, and the screw is fixed to the air conditioner filter sealing plate through the bracket connection; two nuts are installed on the screw, and the two nuts are respectively located on both sides of the positioning plate; a spray pipe runs through the sealing plate of the air-conditioning filter; the spray gun communicates with one end of the spray pipe. The device realizes the cleaning of the back of the air-conditioning evaporation box, and the spraying direction of the cleaning agent is controllable, and can prevent the cleaning agent from being poured back into the cab.

Description

technical field [0001] The invention relates to the relevant technical fields of vehicle engineering and mechanical engineering, in particular to an auxiliary device for cleaning an automobile air conditioner. Background technique [0002] The air conditioning evaporator is one of the key components of the automotive air conditioning system. [0003] As the car is used longer, leaves, dust and insect corpses will gradually accumulate on the surface of the air-conditioning evaporator, and then ferment and rot, resulting in germs and odors. After the air conditioner is turned on, the air with dust and germs will circulate into the cab, threatening the health of drivers and passengers. [0004] Because the polluted air comes from the air conditioner evaporator, not from the outside of the car, the problem still exists after simply changing the air conditioner filter. [0005] In the prior art, there are generally two ways to remove the center console and clean the air-conditi...

Problems solved by technology

However, during the cleaning process, it was found that due to the high pressure of the spray gun and the fact that the air conditioner filter installation port could not be completely sealed, a large amount of cleaning agent was poured back into the cab from the air conditioner filter installation port under the action of high-pressure gas, causing the driver to room is polluted

The mixed liquid blows directly to the face of maintenance personnel, affecting vision and affecting physical health

At the same time, because there is a blower between the center console and the air-conditioning evaporation box, it is difficult to control the spray direction of the nozzle. The oblique spray will cause part of the gas-liquid mixture to directly spray the blower, causing water to enter the blower (cleaning agent enters the blower), which is very serious. Large impact on blower life
