Description
Technical Field
The invention relates to the technical field related to vehicle engineering and mechanical engineering, in particular to a device suitable for cleaning an automobile evaporation tank.
Background
The evaporator box is one of the key components of an automotive air conditioning system.
With the increase of the service time of the automobile, leaves, dust and insect corpses are gradually accumulated on the surface of the evaporation box and then fermented and rotten to generate germs and peculiar smell. After the air conditioner is started, air with dust and germs can be circulated into the cab, and the health of drivers and passengers is threatened.
The problem still remains after simply replacing the air conditioning filter, since the contaminated air comes from the air conditioning evaporator box and not from the outside of the vehicle.
In the prior art, the method generally comprises two modes of disassembling a center console and cleaning an evaporation box by using a disassembly-free center console.
The air conditioner evaporation box can be thoroughly exposed after the central console is disassembled, and the evaporation box can be thoroughly cleaned. However, the whole maintenance process needs a plurality of maintenance personnel to cooperate, and two working days are consumed for completion. Although the mode is good in cleaning effect, time and labor are wasted, the cost is high, and the vehicle cannot be used in the maintenance process.
The cleaning mode of the disassembly-free center console is that an air cleaning agent and an air pump are connected with the same spray gun, then the spray gun is installed with a longer spray pipe, and the spray pipe is directly inserted into an air inlet of an external circulation of the automobile, so that the air cleaning agent is directly blown to the evaporation box under the driving of high-pressure air flow, and the cleaning of the evaporation box is realized.
From the viewpoint of improving the cleaning effect, there are also some visible spray guns at present. For example, chinese patent publication No. CN207225312U provides a visual automobile air conditioner cleaning tool. The instrument can be with air cleaner and high-pressure gas mixture back direct injection evaporating box, and the spray tube front end has the camera. The cleaning effect better than that of a common spray gun can be achieved when the evaporation box is cleaned by adopting the tool.
But no matter which spray gun is adopted, the cleaning mode of the disassembly-free center console cannot completely clean the evaporation box. Because the existing spray guns are directly sprayed on the front surface of the evaporation box and cannot be directly sprayed on the back surface of the evaporation box, only mixed liquid of cleaning agent and condensed water flows on the back surface of the evaporation box in the cleaning process, and dust, leaves and insect corpses adhered to the back surface of the evaporation box cannot be well cleaned.
As a further practice, some car owners and maintenance personnel use the spray pipe to be directly inserted from the mounting port of the air conditioner filter at the lower right of the driving position, so as to achieve the purpose of directly spraying the reverse side of the evaporation box. However, in the cleaning process, the pressure of the spray gun is higher, and the mounting port of the air conditioner filter cannot be completely sealed, so that a large amount of cleaning agent is reversely filled into the cab from the mounting port of the air conditioner filter under the action of high-pressure gas, and the cab is polluted. The mixed liquid is directly blown to the face of maintenance personnel, so that the visual field is influenced, and the body health is influenced. Meanwhile, because the air blower is arranged between the center console and the evaporation box, the spraying direction of the spraying pipe is difficult to control, and the oblique spraying can lead part of the gas-liquid mixture to be directly sprayed to the air blower, so that the water inlet of the air blower (the cleaning agent enters the air blower) is caused, and the service life of the air blower is greatly influenced.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
Example (b): a device for cleaning the evaporator box of a motor vehicle, the structure of which is shown in fig. 1-4, comprising:
an accelerator pedal connecting rod clamping sleeve 9;
the right side of the accelerator pedal connecting rod clamping sleeve 9 is fixedly connected with the lower part of the positioning plate 6;
a screw 8 penetrates through the upper part of the positioning plate 6, the right end of the screw 8 is fixedly connected with the lower part of the bracket 5, and the upper part of the bracket 5 is fixedly connected with the lower part of the sealing plate 1 of the air-conditioning filter;
two nuts 7 are mounted on the screw 8, and the two nuts 7 are respectively positioned on two sides of the positioning plate 6;
a spray pipe 3 penetrates the upper part of the sealing plate 1 of the air conditioner filter.
Preferably, the spray pipe 3 is fixedly connected with a limiting sleeve 4.
Referring to fig. 5, the nozzle 3 includes an input portion 35, a first turn portion 34, an intermediate connection portion 33, a second turn portion 32, and an output portion 31 in this order from the input end to the output end. The intermediate connecting part 33 penetrates through the air conditioner filter sealing plate 1, and the limiting sleeve 4 is fixedly connected to the intermediate connecting part 33.
In view of improving the sealing effect, the sealing ring 2 is mounted on the sealing plate 1 of the air conditioner filter, and the sealing ring 2 is located between the sealing plate 1 of the air conditioner filter and the intermediate connecting portion 33. Normally, the seal ring 2 and the intermediate connecting portion 33 are in a clearance fit.
Before use, the two nuts 7 are loosened so that the screw 8 can freely move axially. And the automobile air-conditioning filter and the original air-conditioning filter sealing plate are disassembled.
During the use, fix accelerator pedal connecting rod cutting ferrule 9 card on accelerator pedal connecting rod, then adjusted the inclination of air conditioner filter closing plate 1, make its accurate lock in air conditioner filter installing port, sealed air conditioner filter installing port. And then the two nuts 7 are screwed to prevent the air conditioner filter sealing plate 1 from loosening. Next, the quick release connector of the spray gun is connected with the input part 35, the spray gun is ensured to be communicated with the air source and the cleaning agent, then the spray gun is opened, and the high-pressure air with the cleaning agent is directly injected to the back surface of the evaporation box, so that the back surface of the evaporation box is cleaned. The insect corpse, the leaves and the dust are mixed with condensed water and cleaning agent and flow out from the bottom of the vehicle.
In the cleaning process, the spray pipe 3 can move left and right and can also rotate by taking the middle connecting part 33 as an axis, so that the reverse side of the evaporation box is thoroughly cleaned. Since the stopper sleeve 4 is mounted on the intermediate connection portion 33, the actual moving distance of the spout 3 corresponds to the distance between the stopper sleeve 4 and the second turn 32. Under the action of the limiting sleeve 4, the nozzle 3 can be prevented from excessively moving and interfering with parts such as a blower and the like. Because the air conditioner filter sealing plate 1 is sealed on the air conditioner filter mounting opening, high-pressure air and cleaning agent cannot flow back to the cab in the cleaning process.
Since the mixed air of the high-pressure air and the detergent is ejected from the output portion 31, the ejection direction of the mixed air can be predicted, and the accident that the mixed air is directly injected into the blower is avoided. Although the mixed liquid that has partial comdenstion water and sanitizer spatters on the air-blower (use traditional spray gun to directly spout the evaporation case openly also can appear comdenstion water and sanitizer splash on the air-blower), but the mixed liquid is for spattering rather than directly spouting, and its dynamics of spattering is less, so rely on self of air-blower sealed just can avoid mixed liquid to get into the air-blower inside, use this device to carry out the clean air-blower life that can not influence basically of evaporation case reverse side.
