[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0029] Please see Figure 1 - Figure 3 This is the first embodiment of the present invention.

[0030] This embodiment provides a high-pressure spray cleaning head for automotive air conditioning evaporator repair, including:

[0031] The bracket 1 has a cleaning mechanism 2 on its inner side, a control mechanism 4 on one end of its inner side, and a drive mechanism 6 on both ends of its inner side.

[0032] The cleaning mechanism 2 includes a water supply tank 21 located inside the support 1. Water spray pipes 22 are evenly fixed on the bottom side of the support 1. An adjusting seat 23 is installed at the bottom end of the water spray pipes 22. Through holes 25 are evenly opened on the circumferential surface of the bottom side of the water spray pipes 22. A water spray hole 26 is opened at the center of the bottom side of the adjusting seat 23. A water valve 27 is fixed at the center of the top side of the support 1. A driven gear 28 is fixed on the circumferential surface of the adjusting seat 23.

[0033] Specifically, the bottom end of the water valve 27 passes through the bracket 1 and connects to the inside of the water supply tank 21. The through hole 25 connects to the spray hole 26. The inner side of the adjusting seat 23 is provided with a threaded groove 24. The adjusting seat 23 is rotatably connected to the spray pipe 22 through the threaded groove 24.

[0034] Furthermore, through the structure of the water spray pipe 22 and the adjusting seat 23, high-pressure water flow or water mist can be sprayed from the water spray hole 26, thereby removing different dust and impurities and improving the cleaning quality and efficiency of the evaporator.

[0035] In use, the bracket 1 is placed on the evaporator. At this time, the water valve 27 can be connected to the high-pressure water source, and the water valve 27 is opened to deliver clean water to the inside of the water tank 21. With the cooperation of the water spray pipe 22, the water is delivered to the inside of the adjusting seat 23 through the through hole 25 and output through the water spray hole 26 on the bottom side of the adjusting seat 23. By rotating the driven gear 28, the distance between the water spray hole 26 and the bottom end of the water spray pipe 22 can be changed, and the high-pressure water flow or water mist sprayed from the water spray hole 26 can be adjusted to thoroughly clean the dust and impurities on the surface of the evaporator and prevent the cooling efficiency inside the car from being affected.

[0036] In summary, through the structure of the cleaning mechanism 2, by setting multiple water spray pipes 22, it can fully spray the surface of the evaporator. Then, with the cooperation of the adjusting seat 23, the distance between the water spray hole 26 and the bottom end of the water spray pipe 22 can be changed, so that the spray head can switch between high-pressure water flow or water mist mode, thoroughly removing dust and impurities from the surface of the evaporator, and improving the quality and efficiency of cleaning. Example

[0037] Please see Figure 4 - Figure 5 This is the second embodiment of the present utility model.

[0038] Specifically, the control mechanism 4 includes a servo motor 41 fixed to one end of the top side of the bracket 1. The output end of the servo motor 41 passes through the bracket 1 and is fixed with a drive gear 42. The drive gear 42 is rotatably connected to the bracket 1. Hollow tubes 3 are fixed at both ends of the bracket 1. Slide rails 43 are symmetrically fixed inside the hollow tubes 3. A first rack 44 is slidably installed inside one slide rail 43, and a second rack 45 is slidably installed inside the other slide rail 43. The first rack 44 meshes with the drive gear 42 and the driven gear 28 respectively, and the second rack 45 meshes with the drive gear 42 and the driven gear 28 respectively.

[0039] Furthermore, by driving the gear 42 in conjunction with the rack, multiple driven gears 28 can be driven to rotate simultaneously, thereby controlling the cleaning mode of the nozzle. The operation is simple and convenient.

[0040] Specifically, the drive mechanism 6 includes a groove 61 opened inside the hollow tube 3, a telescopic plate 62 slidably installed inside the groove 61, positioning holes 63 evenly opened on the surface of the telescopic plate 62, an insert rod 64 slidably inserted through the bottom side of the hollow tube 3, a limit cap 65 fixed to one end of the insert rod 64, a spring 66 fixedly connected between the limit cap 65 and the hollow tube 3, one end of the insert rod 64 being fastened inside the positioning hole 63, an auxiliary roller 5 symmetrically rotated and installed at the bottom side of the hollow tube 3, a rotating roller 68 symmetrically rotated and installed at the bottom side of the telescopic plate 62, a drive motor 67 fixed to the bottom side of the telescopic plate 62, and the output end of the drive motor 67 passing through the telescopic plate 62 and fixedly connected to the rotating roller 68, and an evaporator body 7 placed inside the rotating roller 68 and the auxiliary roller 5.

[0041] Furthermore, the device can be mounted on the evaporator by means of the symmetrically arranged rotating roller 68 and auxiliary roller 5, and during the tilting process, the support 1 is automatically driven to move back and forth, thereby thoroughly cleaning its surface.

[0042] In use, place the evaporator body 7 inside the rotating roller 68 and auxiliary roller 5. Then, pull the limit cap 65 to pull out the insertion rod 64 and push the telescopic plate 62 to extend and retract to the desired position, so that the rotating roller 68 and auxiliary roller 5 can clamp on both sides of the evaporator body 7. Then, release the limit cap 65. Under the action of the spring 66, the insertion rod 64 is driven to re-insert into the positioning hole 63, fixing the position of the rotating roller 68 and auxiliary roller 5. At this time, the drive motor 67 can be controlled to drive the output end rotating roller 68 to rotate, which can drive the device to move on the surface of the evaporator body 7, thereby thoroughly cleaning its surface. During the cleaning process, the servo motor 41 can be controlled to drive the output end drive gear 42 to rotate, thereby causing the racks on both sides to slide in opposite directions inside the slide rail 43, so that it simultaneously drives multiple driven gears 28 to rotate, and adjust multiple nozzles to the desired mode at the same time, so that they spray high-pressure water jets or water mist to remove dust and impurities from the surface of the evaporator.

[0043] In summary, through the structure of the control mechanism 4 and the drive mechanism 6, the spraying mode of multiple nozzles can be changed simultaneously with the cooperation of the rack and pinion. Then, with the cooperation of the rotating roller 68 and the auxiliary roller 5, the device can be fixed on the surface of the evaporator for cleaning operations, thereby realizing the function of automatic cleaning.
