Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a protective air conditioning evaporator for automobiles. Background Technology
[0002] The automotive evaporator is one of the core components of the automotive air conditioning refrigeration system. When the system is operating, the low-temperature, low-pressure liquid refrigerant output from the expansion valve flows into the evaporator pipe. During this process, the liquid refrigerant evaporates rapidly and transforms into a gaseous state. This phase change is accompanied by a strong endothermic reaction, and a large amount of heat is absorbed from the evaporator and the surrounding air, thereby achieving cooling.
[0003] When the evaporator is in use, dust in the air will adhere to the surface of the evaporator. When there is too much dust on the surface of the evaporator, it will form a heat insulation layer on the surface of the evaporator, which will affect the working efficiency of the evaporator. At this time, the staff needs to clean the dust from the evaporator.
[0004] The existing technology has the following drawbacks: the existing automotive evaporators lack a dust removal component for the evaporator. When dust covers the surface of the evaporator, the operator needs to disassemble the car parts in order to clean the evaporator. The dust removal process is cumbersome, time-consuming and labor-intensive. Therefore, a protective air conditioning evaporator for automobiles is proposed to solve the above problems.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1-3This utility model provides an embodiment of a protective air conditioning evaporator for automobiles, comprising a housing 1. Two sets of holes are symmetrically arranged on the left and right sides of the housing 1 to facilitate air entry and exit. An evaporator 2 is fixedly installed on the inner wall of the housing 1. Two sets of openings are provided at the bottom of the housing 1, allowing dust to fall into a collection box 3. A triangular block 8 initially blocks the openings. The collection box 3 is detachably installed at the bottom of the housing 1, collecting dust for later unified processing. An electric telescopic rod 4 is provided on the inner wall of the housing 1. The electric telescopic rod 4 is a device that converts the rotational motion of an electric motor into linear motion. The above is prior art. The technique, without going into too much detail, involves a movable plate 5 fixedly connected to the movable end of the electric telescopic rod 4. A cleaning brush 6 is slidably connected to the inner wall of the movable plate 5. A cylinder is provided on the cleaning brush 6. A slot corresponding to the cylinder is opened on the movable plate 5 to facilitate the vertical movement of the cleaning brush 6. A rectangular plate 7 is fixedly connected to the bottom end of the cleaning brush 6. A movable mechanism is provided on the inner wall of the placement box 1. A disassembly assembly is provided on the inner wall of the placement box 1. The movable mechanism includes a triangular block 8. The inner wall of the front end of the triangular block 8 is elastically connected to the placement box 1 through a movable spring 9. The triangular block 8 passes through and is slidably connected to the inner wall of the placement box 1. A slot corresponding to the triangular block 8 is opened on the placement box 1 to facilitate the back-and-forth movement of the triangular block 8.
[0035] Reference Figures 4-6 The disassembly assembly includes a movable rod 10. The inner sidewall of the movable rod 10 is elastically connected to the placement box 1 via a movable spring 11. The movable rod 10 passes through and is slidably connected to the inner wall of the placement box 1. The placement box 1 has a slot corresponding to the movable rod 10 to facilitate the left and right movement of the movable rod 10. The bottom end of the movable rod 10 is fixedly connected to an insert block 12, which is inserted into the inner sidewall of the collection box 3. There are two sets of insert blocks 12: the right insert block 12 is inserted into the slot on the inner sidewall of the collection box 3, and the left insert block 12 is inserted into the slot on the left sidewall of the collection box 3. The inner sidewall of the movable rod 10 is fixedly connected to one end of the movable spring 11, and the other end of the movable spring 11 is fixedly connected to the inner wall of the right end of the placement box 1. When the movable rod 10 moves to the left, the movable spring 11 is stretched. When resetting, the elastic force of the movable spring 11 is used to reset the movable rod 10.
[0036] Reference Figures 1-3The inner wall of the front end of the triangular block 8 is fixedly connected to one end of the movable spring 9, and the other end of the movable spring 9 is fixedly connected to the inner wall of the placement box 1. When the two sets of triangular blocks 8 separate from each other, the movable spring 9 is compressed. When resetting, the elastic force of the movable spring 9 brings the two sets of triangular blocks 8 closer together. The triangular blocks 8 are inserted into the inner wall of the collection box 3. The collection box 3 has a slot corresponding to the collection box 3. The inner wall of the cleaning brush 6 is in contact with the outer wall of the evaporator 2. The bottom end of the rectangular plate 7 is in contact with the upper surface of the triangular block 8. When the rectangular plate 7 squeezes the triangular block 8, it separates the two sets of triangular blocks 8 from each other. The moving plate 5 is provided with a slanted groove. When the slanted groove squeezes the cleaning brush 6, it makes the cleaning brush 6 move vertically. The collection box 3 is provided with an opening. When the collection box 3 is taken out downward, it will not block the movable rod 10.
[0037] Working principle: When it is necessary to clean the dust on the surface of the evaporator 2, the electric telescopic rod 4, controlled by an external power source, moves the moving plate 5 forward. The inclined groove on the moving plate 5 squeezes the cleaning brushes 6, causing the two sets of cleaning brushes 6 to separate. The two sets of cleaning brushes 6 clean the dust on the evaporator 2. When the lower cleaning brush 6, along with the rectangular plate 7, contacts and squeezes the triangular block 8, the two sets of triangular blocks 8 separate and squeeze the movable spring 9. When the triangular blocks 8 separate, they do not block the opening on the placement box 1, allowing dust to fall into the collection box 3. After the cleaning brushes 6 have cleaned the dust on the surface of the evaporator 2, the electric telescopic rod 4 moves the moving plate 5 backward. The inclined groove on the moving plate 5 squeezes the two sets of cleaning brushes 6 together. As the rectangular plate 7 and the triangular blocks 8 no longer contact each other, the elasticity of the movable spring 9 brings the two sets of triangular blocks 8 together, blocking the opening and preventing dust from overflowing. At this time, the cleaning brushes 6 return to their initial position. To clean the evaporator 2 again, simply repeat the above steps.
[0038] When dust needs to be removed, move the movable rod 10 to the left. The movable rod 10 will compress the moving spring 11, and at the same time, the movable rod 10 will separate the insert 12 from the slot on the collection box 3. At this time, remove the collection box 3 downwards. Then, release the movable rod 10, and use the elasticity of the moving spring 11 to move the movable rod 10 back to the initial position. When the collection box 3 needs to be installed, move the movable rod 10 to the left. When the movable rod 10 and the insert 12 no longer obstruct the collection box 3, align the collection box 3 and insert it into the direction of the placement box 1. Then, release the movable rod 10, allowing the insert 12 to be inserted into the slot of the collection box 3, thus completing the positioning of the collection box 3. If dust needs to be cleaned again, simply repeat the above steps.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
