[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Please refer to Figures 1 to 4 As shown, this utility model provides a cleaning device that can automatically adjust the spray position, spray angle and spray range, automatically adapt to different types of air conditioner bottom cavity structures, accurately target the bottom cavity of the vehicle air conditioner for cleaning, improve the overall cleaning quality, overall cleaning efficiency and cleaning coverage of the vehicle air conditioner. The cleaning device includes a conveyor line 100, a spray mechanism 1, and a cleaning mechanism 2. The vehicle air conditioner can move along the length of the conveyor line 100, which is a hollow structure along its length. The spray mechanism 1 includes a mounting base 11 and a spray assembly 12. The mounting base 11 is located on both sides of the conveyor line 100 along its length and in the cleaning area. The spray assembly 12 is mounted on the mounting base 11 and located in the hollow structure of the cleaning area. The spray assembly 12 can extend from one side of the conveyor line 100 toward the central axis of the conveyor line 100. The spray assembly 12 can move along the length of the conveyor line 100 on the mounting base 11 and can rotate around the vertical axis of the mounting base 11. The cleaning fluid can be sprayed through the spray assembly 12 to the bottom cavity of the vehicle air conditioner. The cleaning mechanism 2 is located on the conveyor line 100 and is used to clean the surface of the vehicle air conditioner. An identification mechanism is installed on one side of the spray mechanism 1 and is electrically connected to the spray mechanism 1.

[0033] Through the coordinated operation of the spraying mechanism 1, the cleaning mechanism 2, and the identification mechanism, the identification mechanism accurately identifies the model of different vehicle air conditioners and the specific location and shape of the bottom cavity before cleaning. Since the identification mechanism and the spraying mechanism 1 are electrically connected, the spraying mechanism 1 can automatically adjust the spray position and angle of the spray assembly 12 based on the air conditioner model and the specific location and shape of the bottom cavity identified by the identification mechanism. This adapts to the bottom cavity structure of different types of vehicle air conditioners, reducing manual intervention and improving cleaning efficiency. By placing the spray assembly 12 on both sides of the conveyor line 100 along its length and within the cleaning area, extending from one side of the conveyor line 100 towards its central axis, the spraying mechanism 1 can cover as much of the width of the conveyor line 100 as possible, effectively cleaning the air conditioner. The cleaning fluid is sprayed onto different areas of the bottom cavity, expanding the cleaning coverage. The spray mechanism 1 includes a mounting base 11 and a spray assembly 12. The spray assembly 12 can move along the length of the conveyor line 100 on the mounting base 11 and rotate around the central axis of the mounting base 11, flexibly adjusting the spray direction. This allows the spray angle and position of the spray assembly 12 to be quickly adjusted according to the bottom cavity position of different vehicle air conditioner models, ensuring precise spray cleaning of the bottom cavity and guaranteeing that the cleaning fluid penetrates deep into the bottom cavity. This avoids leakage caused by inaccurate positioning, improving cleaning coverage and effectiveness. The cleaning mechanism 2 cleans the surface of the vehicle air conditioner, achieving overall cleaning coverage and improving the overall cleanliness of the vehicle air conditioner. Therefore, the cleaning device and vehicle air conditioner cleaning system can automatically adjust the spray position, spray angle, and spray range, adapting to the bottom cavities of different vehicle air conditioner models, significantly reducing manual operation time, and improving the overall cleaning quality, efficiency, and coverage of the vehicle air conditioner.

[0034] The cleaning mechanism may, but is not limited to, employ a cleaning robot, enabling a more comprehensive cleaning of the vehicle's air conditioning surface. Specifically, the spray assembly 12 rotates within a range of 100° to 150° around the vertical axis of the mounting base 11. Furthermore, the identification mechanism includes a waterproof visual recognition device capable of determining the model of the vehicle's air conditioning system by observing the position of the bottom cavity. Since the identification mechanism is electrically connected to the spray mechanism 1, it can control the position and angle changes of the spray mechanism 1, placing it in the cleaning position most suitable for the current air conditioning model, resulting in more precise and thorough cleaning.

[0035] To improve the flexibility of the spray assembly 12, in some examples, the cleaning device further includes a spray drive assembly, which includes a first drive member and a second drive member 13. The first drive member is mounted on the mounting base 11 and connected to the spray assembly 12 to drive the spray assembly 12 to move along the length of the conveyor line 100 on the mounting base 11. The second drive member 13 is mounted on the mounting base 11 and connected to the spray assembly 12 to drive the spray assembly 12 to rotate around the vertical axis of the mounting base 11. The first drive member enables the spray assembly 12 to move along the length of the conveyor line 100 on the mounting base 11, allowing the spray assembly 12 to cover a larger cleaning area and ensuring comprehensive cleaning coverage. The second drive member 13 drives the spray assembly 12 to rotate around the vertical axis of the mounting base 11, further expanding the spray angle and range of the spray assembly 12 and ensuring that the cleaning fluid can contact the bottom cavity of the air conditioner at multiple angles. It is understood that the first drive component may, but is not limited to, using a DC drive motor, and no specific limitation is made here; the second drive component may, but is not limited to, using a pneumatic swing table, and no specific limitation is made here.

[0036] like Figure 1 As shown, specifically, the spray assembly 12 includes a spray pipe 121, a plug 122, a right-angle bend 123, and a rotary joint 124. The plug 122 is installed at the end of the spray pipe 121 furthest from the mounting base 11, and the end of the spray pipe 121 closest to the mounting base 11 is connected to the rotary joint 124 via the right-angle bend 123. Cleaning fluid can flow into the spray pipe 121 through the rotary joint 124. The rotary joint 124 is connected to a second driving member 13, which can drive the rotary joint 124 to rotate the spray pipe 121 around the vertical axis of the mounting base 11. The plug 122 is installed at the end of the spray pipe 121 furthest from the mounting base 11. One end of the mounting base 11 is sealed off from the spray pipe 121 port, which effectively prevents the cleaning liquid from flowing out of the spray pipe 121 port, ensuring that the cleaning liquid is concentrated and sprayed onto the target area, thus avoiding waste of cleaning liquid; the right-angle bend 123 turns the cleaning liquid from the direction of the mounting base 11 to the direction of the spray pipe 121, changing the liquid flow from vertical to horizontal, thus optimizing the structural layout of the cleaning device; the rotary joint 124, in cooperation with the second drive component 13, enables the spray pipe 121 to rotate freely around the vertical axis of the mounting base 11, adjusting the spray direction and angle, so that the spray pipe 121 can cover a larger cleaning area and reduce blind spots.

[0037] To improve the sealing and stability of the rotary joint 124, in some embodiments, the rotary joint 124 includes a housing, a rotating shaft, a bearing support, and multiple sealing rings. The rotating shaft is located inside the housing, with one end screwed to a right-angle bend 123 and a sealing ring at the connection point; the other end of the rotating shaft is fixedly connected to a second drive member 13 and a sealing ring at the connection point; the bearing support is located between the housing and the rotating shaft to support the rotating shaft; a pipe joint 125 is provided on the side wall of the housing for connecting the cleaning fluid pipe; the second drive member 13 can drive the rotating shaft to rotate the right-angle bend 123 along the axis of the rotating shaft; wherein, multiple sealing rings are provided at the connection points of the rotary joint 124 with other structures to improve sealing and reduce the possibility of cleaning fluid leakage; the bearing support provides support for the rotating shaft, reducing friction and shaking caused by rotation inside the rotating shaft; the pipe joint 125 on the side wall of the housing makes the supply and connection of the cleaning fluid easier and reduces the complexity of the pipe laying process. The other end of the rotating shaft can be connected to the second drive component 13 via a flange connector 14. The flange connector 14 makes the connection between the two more stable, enabling efficient power transmission and ensuring that the cleaning device can rotate effectively.

[0038] To improve the coverage of the spray, in some embodiments, the spray pipe 121 is provided with multiple nozzles 126. These nozzles 126 are distributed sequentially and at intervals from one side of the conveyor line 100 towards its central axis, with each nozzle 126 spraying upwards towards the conveyor line 100. This sequential and spaced distribution of the nozzles 126 along the central axis of the conveyor line 100 ensures complete coverage of the cleaning area. The upward spray direction of the nozzles 126 helps to directly spray the cleaning fluid onto the surface of objects in the bottom cavity of the vehicle's air conditioning system, enhancing the cleaning effect. Furthermore, the multiple nozzles 126 can be evenly distributed along the central axis of the conveyor line 100 on the spray pipe 121. This even distribution ensures that the spray liquid is evenly sprayed onto the object surface, thereby improving cleaning efficiency and avoiding blind spots or missed areas.

[0039] To improve the precise positioning of the spray mechanism 1, in some embodiments, the spray mechanism 1 further includes a guide member. The guide member is disposed on the mounting base 11 along the length of the conveyor line 100, and the spray assembly 12 is slidably engaged with the guide member. The guide member's arrangement along the length of the conveyor line 100 and the slidable engagement with the spray assembly 12 help to precisely control the position and movement trajectory of the spray assembly 12, ensuring that the nozzles 126 always cover a specific area of ​​the conveyor line 100, avoiding blind spots. It is understood that the guide member can be, but is not limited to, a guide rail; no specific limitation is made here.

[0040] In some embodiments, the cleaning device includes multiple sets of spray mechanisms 1, which are sequentially arranged on both sides of the conveyor line 100 along the conveyor length direction. The multiple sets of spray mechanisms 1 are alternately arranged along both sides of the conveyor line 100, providing comprehensive and uniform cleaning coverage to ensure all-around cleaning of the surfaces of items on the conveyor line 100. Furthermore, different sets of spray mechanisms 1 can spray cleaning liquids of varying strengths, thereby achieving a more efficient cleaning effect. For example, two sets of spray mechanisms 1 can be set up, with the first set spraying a chemical cleaning agent and the second set spraying clean water. Through the control system, during cleaning, the first set of spray mechanisms 1 can be activated first to perform a preliminary cleaning of the vehicle's air conditioning system using a chemical cleaning agent, removing stubborn stains and grease from the surface. Then, the second set of spray mechanisms 1 is activated to spray clean water for rinsing, ensuring thorough removal of any remaining cleaning agent. This method further improves the cleaning effect, resulting in a more thorough cleaning of the vehicle's air conditioning system.

[0041] Combination Figure 3 and Figure 4 As shown, this utility model also provides a vehicle air conditioning cleaning system, including the cleaning device and tray 3 as described in any of the above embodiments. The vehicle air conditioner is placed on the tray 3, and the tray 3 is placed on the conveyor line 100. The conveyor line 100 can transport the tray 3 to the spray assembly 12 above the cleaning area. The tray 3 includes a base plate 31 and a raised piece 32. The base plate 31 has a grid structure, and the raised piece 32 is provided on one side of the base plate 31. The cleaning device can automatically adjust the spray position, spray angle, and spray range to automatically adapt to the bottom cavity structure of different types of air conditioners, accurately aligning the bottom cavity of the vehicle air conditioner for cleaning, improving the overall cleaning quality, overall cleaning efficiency, and cleaning coverage of the vehicle air conditioner. The grid structure of the base plate 31 of the tray 3 can effectively allow the cleaning fluid to flow smoothly, ensuring that the liquid can evenly cover the vehicle air conditioner during the cleaning process, improving the cleaning effect. The raised piece 32 provided on one side of the base plate 31 can appropriately raise one side of the vehicle air conditioner, ensuring that the liquid inside the air conditioner can automatically flow out after cleaning, thereby reducing the accumulation of residual liquid and keeping the inside of the air conditioner dry.

[0042] like Figure 3 As shown, in order to prevent the vehicle air conditioner from slipping, in some embodiments, a stop 33 is provided on the side of the base plate 31 to limit the displacement of the vehicle air conditioner; wherein, by setting the stop 33, the displacement of the vehicle air conditioner can be effectively limited, ensuring that the air conditioner maintains a stable position during the cleaning process, effectively preventing the risk of the vehicle air conditioner slipping during the cleaning process, protecting the bottom of the air conditioner and other components from accidental damage, and improving safety and the stability of the cleaning operation.

[0043] like Figure 4As shown, in order to stabilize the position of the tray 3, in some embodiments, the vehicle air conditioning cleaning system also includes a limiting component 4. The limiting component 4 is vertically and vertically disposed on the conveyor line 100 along the height direction of the conveyor line 100 to limit the movement of the tray 3 after it has transported the vehicle air conditioner to the position above the spray mechanism 1. The setting of the limiting component 4 can effectively limit the movement of the tray 3, ensuring that the vehicle air conditioner is only positioned above the spray mechanism 1, and avoiding the reduction of cleaning accuracy due to excessive movement.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
