[0002] A car wash machine is a machine that uses computer-controlled brushes and high-pressure water to automatically clean cars. It can be divided into automatic car wash machines and coin-operated car wash machines. It mainly consists of a control system, electrical circuits, air circuits, water circuits, and mechanical structures. Car wash machines are characterized by simple operation, an attractive appearance, and minimal damage to car paint. In recent years, they have been widely used in the automotive service industry.

[0003] Existing car wash machines cannot identify car models and adjust the height, length, and shape of the car wash spray nozzles according to the size of the car model. As a result, some spray nozzles are longer than the vehicle itself during the washing process, which prevents the nozzles from effectively spraying the vehicle surface, leading to increased costs and wasted water resources.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The present invention, through the setting of a dot matrix detection plate, a first spray frame, a second spray frame, an electric telescopic rod, a telescopic tube, and a drive motor, enables the equipment to have the function of detecting the size of vehicle models, and adjusts the length, height, and shape of the spray area according to the size of the vehicle, so that the spray area is more suitable for different vehicles, and the whole process can be automated and easy to operate.

[0021] Specifically, the vehicle enters the inspection chamber and moves to the dot matrix detection plate at the bottom. The infrared emitter is activated, with part of the upper infrared emitter blocked by the car, while the other part connects to the lower infrared receiver. The receiver sends a signal back to the controller. The controller, based on the dot matrix position of the received infrared receiver, creates a dot matrix of the areas blocked by the car from other unreceived infrared receivers. This dot matrix provides a rough view of the vehicle's shape. The vehicle length is determined by the length of the dot matrix obstruction and the number of dots. Similarly, the side dot matrix detection plate detects the dot matrix obstruction range on the sides of the car, obtaining a side-view dot matrix image to easily determine the vehicle's length. This solves the problem of existing car wash machines being unable to identify car models and adjust the height, length, and shape of the spray nozzles accordingly. This results in some spray nozzles being longer than the vehicle itself, preventing effective spraying and increasing costs and wasting water resources.

[0022] 2. After obtaining the vehicle dimensions, compare them with the dimensions pre-entered into the controller to determine whether the vehicle is a large or small vehicle. When the vehicle is small, the drive motor rotates the second spray frame, causing it to face downwards and shortening the length of the spray area, thus avoiding water waste due to excessive length. More specifically, after the second spray frame is rotated and placed vertically, its side interface is magnetically attached to the valve port of the second control valve. Opening the second and third control valves allows liquid to flow from the first spray pipe into the multi-port pipe and reach the second spray pipe for spray cleaning. When the vehicle is large, the drive motor rotates the second spray frame to a horizontal position. The upper connector is aligned with the second control valve port, and the third control valve at the upper connector is opened, allowing liquid to flow from the upper connector into the multi-port pipe and then into the second spray pipe for spray cleaning. The electric telescopic rod can move the first spray frame up and down, adjusting its position to facilitate spray cleaning of vehicles of different sizes and heights. The telescopic pipe is flexible, extending as the electric telescopic rod descends and retracting as it rises. The telescopic pipe connects to the delivery pipe of the liquid storage tank, allowing liquid to enter the spray frame below for spraying. This structure allows the length, shape, and height of the spray area to be adjusted according to the vehicle size, reducing water waste and lowering costs. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figure 1-6 An embodiment of the present invention provides: an automatic vehicle model recognition personalized car wash intelligent car wash machine, including a detection chamber 1, a cleaning chamber 2 is provided at the rear end of the detection chamber 1, and a controller 40 is installed on the outer wall of the detection chamber 1;

[0032] Also includes:

[0033] The dot matrix detection board 3 is installed on the four sides of the inner wall of the detection chamber 1. The dot matrix detection board 3 is divided into two groups: the upper and lower and the left and right. Multiple infrared receivers 4 and infrared transmitters 5 are installed on the outer wall of the dot matrix detection board 3. The infrared receivers 4 and infrared transmitters 5 are connected to each other. The infrared receivers 4 and infrared transmitters 5 are distributed in a dot matrix pattern. The infrared receivers 4 are electrically connected to the input terminal of the controller 40.

[0034] The first spray frame 15 is installed inside the cleaning chamber 2. A telescopic tube 14 is installed at the middle position above the first spray frame 15. Electric telescopic rods 16 are installed at both ends of the telescopic tube 14. The telescopic end of the electric telescopic rod 16 is combined with the first spray frame 15. The control end of the electric telescopic rod 16 is wirelessly connected to the output end of the controller 40.

[0035] A bracket 18 is provided at both ends of the first spray frame 15. A second spray frame 19 is provided at the middle position of the bracket 18. A drive motor 24 is installed on the outer wall of the bracket 18. The control end of the drive motor 24 is wirelessly connected to the output end of the controller 40. A transmission shaft 25 is provided at the output end of the drive motor 24. A rotating platform 26 is installed at one end of the transmission shaft 25. The drive motor 24 is connected to the rotating platform 26 through the transmission shaft 25. A driven platform 27 is provided at the rear end of the second spray frame 19. The rotating platform 26 and the driven platform 27 are both assembled and installed with the front and rear ends of the second spray frame 19 by screws.

[0036] The upper surface of the second spray frame 19 is provided with an upper interface 22, and the side of the second spray frame 19 near the first spray frame 15 is provided with a side interface 29. Both the upper interface 22 and the side interface 29 are provided with annular magnetic blocks 23.

[0037] By setting up the dot matrix detection plate 3, the first spray frame 15, the second spray frame 19, the electric telescopic rod 16, the telescopic pipe 14, and the drive motor 24, the equipment can detect the size of the vehicle model and adjust the length, height and shape of the spray area according to the size of the vehicle, so that the spray area is more suitable for different vehicles. The whole process can be automated and is easy to operate.

[0038] Specifically, the vehicle enters the detection chamber 1 and moves to the dot matrix detection plate 3 at the bottom, turning on the infrared emitter 5. Part of the upper infrared emitter 5 is blocked by the car, while the other part is connected to the lower infrared receiver 4. The infrared receiver 4 feeds back a signal to the controller 40. The controller 40, based on the dot matrix position of the infrared receiver 4, forms a dot matrix of the other infrared receivers 4 that are not receiving feedback, which is blocked by the car. The approximate shape of the vehicle can be obtained through this dot matrix. Based on the length of the dot matrix and the number of dots, the length of the vehicle can be obtained. Similarly, the dot matrix detection plate 3 on the side is used to detect the dot matrix occlusion range on the side of the car to obtain a dot matrix image from the side view of the car, which is convenient for determining the length of the car body.

[0039] After obtaining the vehicle dimensions, they are compared with the dimensions pre-entered in the controller 40. The comparison determines whether the vehicle is a large or small vehicle. When the vehicle is small, the drive motor 24 drives the second spray frame 19 to rotate. By rotating, the second spray frame 19 is vertically downward, which shortens the length of the spray area and avoids the phenomenon of water wastage due to excessive length.

[0040] More specifically, after the second spray frame 19 is rotated and placed vertically, the side interface 29 of the second spray frame 19 is fixed to the valve port of the second control valve 21 by the annular magnetic block 23. Opening the second control valve 21 and the third control valve 30 allows the liquid to flow from the first spray pipe 20 into the multi-port pipe 28 and reach the second spray pipe 31 for spray cleaning.

[0041] When the vehicle is a large vehicle, the drive motor 24 drives the second spray frame 19 to rotate into a horizontal state, so that the upper interface 22 is connected to the valve port of the second control valve 21, and the third control valve 30 at the upper interface 22 is opened, so that the liquid can flow from the upper interface 22 into the multi-port pipe 28 and into the second spray pipe 31 for spray cleaning.

[0042] The electric telescopic rod 16 can drive the first spray frame 15 to move up and down. By moving up and down, the position of the first spray frame 15 can be adjusted to facilitate spraying and cleaning operations on vehicles of different sizes and heights. The telescopic pipe 14 is telescopic and can be extended as the electric telescopic rod 16 descends and retracted as the electric telescopic rod 16 rises. The telescopic pipe 14 is used to connect to the delivery pipe 13 of the liquid storage tank 9, so that the liquid can enter the spray frame below through the telescopic pipe 14 for spraying operations.

[0043] After the spraying operation, the water stains on the vehicle body are dried by the air dryer at 32 points. Of course, the water used in the spraying and cleaning process is pressurized water, which is pressurized by a pump. The spraying water pressure is adjusted according to the user's actual spraying and cleaning needs.

[0044] Please see Figure 4 The first spray frame 15 is equipped with a first spray pipe 20. A second control valve 21 is installed at both ends of the first spray pipe 20. The valve port of the second control valve 21 is magnetically connected to the annular magnetic block 23. The control end of the second control valve 21 is wirelessly connected to the output end of the controller 40.

[0045] The second control valve 21 is used to control the opening and closing state of the first spray pipe 20. When it is open, it can transport part of the liquid in the first spray pipe 20 to the second spray pipe 31. When it is closed, the liquid remains in the first spray pipe 20 for spraying. The annular magnetic block 23 can be connected and combined by magnetic attraction, and the magnetic attraction point can be easily separated during rotation.

[0046] Please see Figure 5The second spray frame 19 is equipped with a multi-port pipe 28. The lower end of the multi-port pipe 28 is equipped with a second spray pipe 31, which extends into the second spray frame 19. The three ports of the multi-port pipe 28 are respectively connected to the upper interface 22, the side interface 29 and the second spray pipe 31. The upper interface 22, the side interface 29 and the multi-port pipe 28 are connected by a third control valve 30 through a flange. The control end of the third control valve 30 is wirelessly connected to the output end of the controller 40.

[0047] Please see Figure 3 Multiple second spray heads 17 are provided at intervals on the outer walls of the first spray frame 15 and the second spray frame 19, and the second spray heads 17 are connected to the first spray pipe 20 and the second spray pipe 31 respectively through pipelines.

[0048] By setting multiple second spray heads 17, the spray cleaning range can be increased, and the car can be sprayed and cleaned evenly.

[0049] Please see Figure 2 An L-shaped mounting bracket 8 is installed above the electric telescopic rod 16. A small liquid storage tank 9 is installed above the L-shaped mounting bracket 8. Multiple first spray heads 11 are arranged horizontally at intervals on the lower surface of the L-shaped mounting bracket 8, and the first spray heads 11 are connected to the liquid storage tank 9 through pipelines.

[0050] The liquid storage tank 9 is used to store the liquid required for spray cleaning. The liquid is a mixture of water and car cleaner, which is used to remove stains from the car surface.

[0051] The first spray head 11 is located above the car. The top of the car is sprayed and cleaned by the first spray head 11, which raises the cleaning surface and improves the cleaning efficiency.

[0052] Please see Figure 2 A first control valve 12 is installed on the side wall of the storage tank 9, and the control end of the first control valve 12 is wirelessly connected to the output end of the controller 40. A delivery pipe 13 is installed at one end of the first control valve 12, and one end of the delivery pipe 13 is connected to the telescopic pipe 14. A level gauge 10 is installed on the outer wall of the storage tank 9, and the output end of the level gauge 10 is wirelessly connected to the input end of the controller 40.

[0053] The first control valve 12 is used to control the opening and closing state of the liquid storage tank 9. When it is open, the liquid in the liquid storage tank 9 can be transported to the telescopic pipe 14 through the delivery pipe 13. The level gauge 10 is used to detect the liquid level change of the liquid storage tank 9 and feed back the signal to the controller 40 so that the user can know the amount of liquid stored inside.

[0054] Please see Figure 2An annular guide rail 6 is installed above the L-shaped mounting bracket 8, and the annular guide rail 6 is located at the top inside the cleaning chamber 2. The annular guide rail 6 includes a guide rail slider 7, and the L-shaped mounting bracket 8 is assembled with the guide rail slider 7 by screws.

[0055] The circular guide rail 6 is used to drive the guide rail slider 7 to move in a circular motion with the spray frame below. Through the circular movement, the spray frame sprays around the car body, so that all surfaces of the car can be sprayed and cleaned, making it convenient for users.

[0056] Please see Figure 1 , Figure 2 Dryers 32 are installed on the inner walls of both sides of the cleaning chamber 2. Fans 33 are installed inside the dryers 32. A mesh cover 34 is installed at the rear end of the fans 33 and the mesh cover 34 is located on the outer wall of the side of the cleaning chamber 2.

[0057] After cleaning, turn on the air dryer 32 and use the fan 33 to dry the car surface, achieving a quick drying effect after cleaning.

[0058] Please see Figure 1 , Figure 2 , Figure 6 The bottom of the cleaning chamber 2 is provided with a bottom plate 35. Multiple grid openings 39 are provided on the outer wall of the bottom plate 35. Drainage channels 36 are provided on both sides of the bottom plate 35. A through-hole plate 37 is provided between the drainage channel 36 and the bottom plate 35. A drain outlet 38 is provided at one end of the drainage channel 36.

[0059] Wastewater generated during cleaning falls from the grid opening 39 and moves from the through-hole plate 37 into the drainage channels 36 on both sides, and is finally discharged outward from the drain outlet 38, so that the wastewater generated can be discharged to the outside of the cleaning chamber 2 for centralized treatment, avoiding a large amount of water remaining inside.

[0060] Working principle: The vehicle drives into the detection chamber 1 and moves to the dot matrix detection plate 3 at the bottom. The infrared transmitter 5 is turned on. Part of the upper infrared transmitter 5 is blocked by the car, while the other part is connected to the infrared receiver 4 below. The infrared receiver 4 feeds back a signal to the controller 40. The controller 40 forms a dot matrix that is blocked by the car based on the dot matrix position of the infrared receiver 4 and the other infrared receivers 4 that did not feed back a signal. The approximate shape of the vehicle can be obtained through this dot matrix. The length of the vehicle can be obtained based on the length of the dot matrix and the number of dots. Similarly, the dot matrix detection plate 3 on the side is used to detect the dot matrix occlusion range on the side of the car to obtain a dot matrix image from the side view of the car, which is convenient for judging the length of the car body.

[0061] After inspection, the vehicle moves from inspection chamber 1 into cleaning chamber 2. After obtaining the vehicle dimensions, they are compared with the dimensions pre-entered in controller 40 to determine whether the vehicle is a large or small vehicle. When the vehicle is small, drive motor 24 drives the second spray frame 19 to rotate, which makes the second spray frame 19 vertically downward, shortening the length of the spray area. After the second spray frame 19 is rotated and placed vertically, the side interface 29 of the second spray frame 19 is attached to the valve port of the second control valve 21 by the annular magnetic block 23. Opening the second control valve 21 and the third control valve 30 allows liquid to flow from the first spray pipe 20 into the multi-port pipe 28 and reach the second spray pipe 31. Water is then sprayed from each second spray head 17 through the second spray pipe 31 and the first spray pipe 20 to spray and clean the car.

[0062] When the vehicle is a large vehicle, the drive motor 24 drives the second spray frame 19 to rotate into a horizontal state, so that the upper interface 22 is connected to the valve port of the second control valve 21, and the third control valve 30 at the upper interface 22 is opened, so that the liquid can flow from the upper interface 22 into the multi-port pipe 28 and into the second spray pipe 31 for spray cleaning.

[0063] The first spray head 11 is located above the car, and the top of the car is sprayed and cleaned through the first spray head 11.

[0064] The circular guide rail 6 is used to drive the guide rail slider 7 to move in a circular motion with the spray frame below. Through the circular motion, the spray frame sprays around the car body, so that all surfaces of the car can be sprayed and cleaned.

[0065] After cleaning, turn on the air dryer 32 and use the fan 33 to dry the car surface and blow off the water. The wastewater generated during cleaning falls from the grille opening 39 and moves from the through-hole plate 37 into the drainage channels 36 on both sides, and is finally discharged outward from the drain outlet 38, so that the wastewater generated can be discharged to the outside of the cleaning chamber 2 for centralized treatment.

[0066] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
