Description

Technical Field

[0001] This application relates to the field of car wash machines, and more particularly to a vehicle cleaning method based on a car wash machine, a car wash machine, and a readable storage medium. Background Technology

[0002] With the continuous development of society and economy, the number of motor vehicles has grown rapidly, which brings with it the problem of car washing. At present, car wash shops are still the main way to wash cars, but the number of car wash shops is limited and the water consumption is large, which is time-consuming and labor-intensive. In order to solve this problem, some self-service car wash systems have begun to appear on the market.

[0003] However, in the process of cleaning a car, existing self-service car wash systems can cause solid particles to be present on the car's surface. The rollers of the car wash machine can push these solid particles against the car's surface, which can easily scratch the paint. Summary of the Invention

[0004] This application provides a vehicle cleaning method based on a car wash machine, a car wash machine, and a readable storage medium to solve the problem that the rollers of the car wash machine easily scratch the paint surface of the car during the cleaning process.

[0005] In a first aspect, this application provides a vehicle cleaning method based on a car wash machine, the car wash machine including a handle module, the handle module including a handle body and a roller assembly, the roller assembly including a roller body and a roller drive component, the method including: Control the car wash machine to turn on in order to clean the surface of the car; During the cleaning of the vehicle surface, the roller drive is controlled to drive the roller body to rotate relative to the handle body in a first rotation direction to perform rolling cleaning on the vehicle surface in contact with the roller body. When the roller body rotates in the first rotation direction, the side of the roller body closest to the forward direction of the handle module rotates towards the side closest to the handle body. The forward direction is the direction of movement of the handle module when it is held and pushed.

[0006] Secondly, this application also provides a car wash machine, comprising: Base station module; A handle module, comprising a handle body, a roller assembly, and a control component, wherein the roller assembly comprises a roller body and a roller drive component, the roller body is connected to the handle body, and the control component is disposed on the handle body and electrically connected to the roller drive component, the control component being used to perform the vehicle cleaning method based on the car wash machine as described above; A pipe module, wherein the handle module is connected to the base station module via the pipe module; The liquid circuit system includes at least a liquid storage device disposed in the base station module and a pipeline module disposed at least partially in the pipeline module, wherein the pipeline module is connected to the liquid storage device and is used to transmit cleaning foam or cleaning fluid provided by the liquid storage device.

[0007] Thirdly, this application also provides a readable storage medium storing a computer program that, when executed by a processor, causes the processor to implement the vehicle cleaning method based on a car wash machine as described above.

[0008] This application provides a vehicle cleaning method, a car wash machine, and a readable storage medium based on a car wash machine. During the cleaning process of the car surface, the roller body is driven to rotate relative to the handle body in a first rotation direction by controlling the roller drive component to perform rolling cleaning on the vehicle surface in contact with the roller body. When the roller body rotates in the first rotation direction, the surface of the roller body on the side closer to the handle module in the forward direction rotates towards the side closer to the handle body. This allows grit or other hard dirt on the vehicle surface to be collected after being attached to the roller body and rotated around the side closer to the forward direction during the movement of the handle module on the vehicle surface. This prevents the grit or other hard dirt attached to the vehicle surface from sliding on the vehicle surface and causing damage, thereby improving the protection of the vehicle surface and the cleaning effect of the handle module.

[0009] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the disclosure of the embodiments of this application. Attached Figure Description

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] It should also be understood that the terminology used in this application specification is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this application specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0015] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0016] Currently, in the process of cleaning cars, existing self-service car wash systems can cause solid particles to be present on the car's surface. The rollers of the car wash machine can push these solid particles to rub against the car's surface, which can easily scratch the car's paint.

[0017] Therefore, this application provides a vehicle cleaning method, a car wash machine, and a readable storage medium based on a car wash machine. This method enables the collection of grit or other hard dirt on the vehicle surface as the handle module moves across the vehicle surface. After the grit or other hard dirt adheres to the roller body, it rotates around the side closest to the direction of travel and is collected. This prevents the grit or other hard dirt from sliding on the vehicle surface and causing damage, thereby improving the protection of the vehicle surface and the cleaning effect of the handle module.

[0018] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the modular structure of a car wash machine provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a car wash machine provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of a handle module in a car wash machine, provided in an embodiment of this application.

[0020] Specifically, the car wash machine 1000 includes a base station module 300, a handle module 100, a pipe module 200, and a liquid system 500. The handle module 100 is connected to the base station module 300 via the pipe module 200. The liquid system 500 includes at least a liquid storage device 501 located in the base station module 300 and a pipe module 502 at least partially located in the pipe module 200, with the pipe module 502 connected to the liquid storage device 501. Further, in some embodiments, a portion of the pipe module 502 is located in the pipe module 200, while another portion may be located in the base station module 300 and / or the handle module 100.

[0021] It should be noted that the handle module 100 can be used by a user to clean a target surface, such as the exterior surface of a vehicle (hereinafter referred to as vehicle surface 600). As one embodiment, the handle module 100 can obtain cleaning fluid stored in the liquid storage device 501 through the pipeline module 502, such as clean water, water containing coating solution, foam liquid, etc., to clean the vehicle surface 600.

[0022] The handle module 100 is described in detail below. The handle module 100 has a forward direction A, which is the direction of movement of the handle module 100 when it is held and pushed. It should be understood that when the user holds and operates the handle module 100, the handle module 100 is attached to the vehicle surface 600, and the handle module 100 is pushed in the forward direction A to clean the vehicle surface 600 to which the handle module 100 is attached.

[0023] like Figures 1 to 4 As shown, specifically, the handle module 100 includes at least a handle body 10, a spray assembly 70, a roller assembly 20, a control assembly (not shown in the figure), a spray washing assembly 80, and a scraper assembly 90. The spray assembly 70, the roller assembly 20, the spray washing assembly 80, and the scraper assembly 90 are all mounted on the handle body 10.

[0024] The control component may include a controller for executing the vehicle cleaning method based on a car wash machine as described in any one of the embodiments of this application. The foaming assembly 70 includes a first nozzle 71 for spraying cleaning foam. The roller assembly 20 includes at least a roller body 21, which is mounted on the handle body 10 and is rotatable relative to the handle body 10. The spray washing assembly 80 is mounted on the handle body 10 and includes a second nozzle 81 for spraying cleaning fluid. The scraper assembly 90 is mounted on the handle body 10. Specifically, the first nozzle 71 is used to spray cleaning foam provided by the liquid storage device 501 and transmitted via the pipeline module 502, and the second nozzle 81 is used to spray cleaning fluid provided by the liquid storage device 501 and transmitted via the pipeline module 502.

[0025] like Figure 5As shown, the handle body 10 further includes a liquid supply channel 15, which can be used to provide cleaning foam to the first nozzle 71 and / or cleaning fluid to the second nozzle 81. It should be noted that the cleaning fluid can be a mixture of water and coating solution, or simply water, or other liquids with cleaning effects.

[0026] It should be noted that the roller body 21 is used to perform rolling cleaning on the vehicle surface 600 that it contacts. Similarly, the scraper assembly 90 is used to perform wiping, brushing, and other operations on the vehicle surface 600 that it contacts, removing stains, dust, etc., thereby cleaning the vehicle surface 600. The spray washing assembly 80 is used to rinse the vehicle surface 600 to wash away dirt. The foam spraying assembly 70 is used to supply cleaning foam to the vehicle surface 600 before performing wiping, brushing, and other operations, thereby improving the cleaning effect of the roller assembly 20, scraper assembly 90, and other cleaning components on the vehicle surface 600. In addition, the scraper assembly 90 is also used to clean the residual sewage on the vehicle surface 600. This sewage is mainly generated during the spraying and washing of the target area by the second nozzle 81, and may also be generated during the spraying and rolling cleaning of the target area with cleaning foam.

[0027] Based on this handle module 100, a cleaning process for a vehicle surface 600 includes: spraying cleaning foam onto a target area of ​​the vehicle surface 600; using a rotating roller body 21 to roll and clean the target area sprayed with cleaning foam; then spraying the target area with cleaning fluid; and finally scraping the target area and cleaning any residual wastewater on the target area. This handle module 100 integrates a foam spraying assembly 70, a roller assembly 20, a spraying assembly 80, and a scraper assembly 90. Therefore, using the provided handle module 100 can complete multiple steps for cleaning the vehicle surface 600, saving car washing time and the number of parts required for car washing.

[0028] like Figure 5 As shown, in some embodiments, a scraper 13 extending toward the drum body 21 is also formed at the sludge collection port 12. The scraper 13 is used to scrape off the dirt collected on the surface of the drum body 21 during the rotation of the drum body 21.

[0029] Specifically, during the rotation of the roller body 21, the scraper 13 can be used to scrape the surface of the roller body 21 and / or squeeze the roller body 21 to scrape off the dirt (such as sewage, dust, mud, etc. on the roller body 21) collected by the roller body 21.

[0030] In some implementations, such as Figure 4As shown, the roller body 21 is configured to rotate relative to the handle body 10 in a first rotation direction B. When the roller body 21 rotates in the first rotation direction B, the surface of the roller body 21 on the side closer to the forward direction A rotates towards the side closer to the handle body 10.

[0031] like Figures 4 to 6 As shown, the roller assembly 20 includes at least a roller body 21 and a roller drive 22. The roller body 21 is mounted on the handle body 10. The roller drive 22 is connected to the handle body 10 and the roller body 21 and is used to drive the roller body 21 to rotate relative to the handle body 10 in a first rotation direction B to perform rolling cleaning on the vehicle surface 600 that the roller body 21 contacts. When the roller body 21 rotates in the first rotation direction B, the side of the roller body 21 that is closer to the forward direction A rotates toward the side that is closer to the dirt collection port 12 so that the dirt collected on the surface of the roller body 21 can enter the dirt collection channel 11 through the dirt collection port 12.

[0032] It should be noted that the rotation method of the drum body 21 can be found in [reference]. Figure 4 , Figure 4 The illustration shows the scene where the main body of the roller 21 rotates along the first rotation direction B.

[0033] It should be noted that, since the roller drive 22 drives the roller body 21 to rotate relative to the handle body 10 along the first rotation direction B, when the handle module 100 is held and pushed to move on the vehicle surface 600 to clean the vehicle surface 600, the roller body 21 can collect dirt from the vehicle surface 600. The roller body 21 rotates around the side closer to the forward direction A to transfer the dirt attached to the vehicle surface 600 to a position opposite to the dirt collection port 12, and then the dirt can enter the dirt collection channel 11 through the dirt collection port 12.

[0034] Furthermore, as the handle module 100 moves across the vehicle surface 600, grit or other hard dirt on the vehicle surface 600, after adhering to the roller body 21, will rotate around the side closest to the forward direction A to a position opposite to the dirt collection port 12 and be collected. This prevents the grit or other hard dirt adhering to the vehicle surface 600 from sliding on the vehicle surface 600 and causing damage to the vehicle surface 600, thereby improving the cleaning effect of the handle module 100 and its protective effect on the vehicle surface 600.

[0035] In some embodiments, the rotation direction of the roller body 21 is not limited to the first rotation direction B, but can also be a second rotation direction opposite to the first rotation direction B, to adapt to various cleaning needs. The roller body 21 can rotate in the second rotation direction under the drive of the roller drive member 22 and / or under the operation of the user.

[0036] like Figure 4 As shown, in some embodiments, the handle body 10 includes a grip portion 16 for holding and a cleaning body portion 17 connected to the grip portion 16. The scraper assembly 90, the second nozzle 81, and the roller body 21 are all disposed on the cleaning body portion 17, and a liquid supply connection port 151 is opened on the grip portion 16. Furthermore, the first nozzle 71 is also disposed on the cleaning body portion 17.

[0037] Specifically, the grip portion 16 and the cleaning body portion 17 are disposed on opposite sides of the handle body 10. As explained above, the scraper assembly 90, the second nozzle 81, and the roller body 21 are used to perform different cleaning processes on the vehicle surface 600. By disposing of the scraper assembly 90, the second nozzle 81, and the roller body 21 on the cleaning body portion 17, it is convenient to directly push the cleaning body portion 17 onto the vehicle surface 600 during use to perform multiple cleaning processes on the same target area of ​​the vehicle surface 600. Moreover, disposing the grip portion 16 and the cleaning body portion 17 on opposite sides of the handle body 10 is more ergonomic, making it easier for the user to hold the handle module through the grip portion 16, adhere the handle module 100 to the vehicle surface 600, and push the handle module 100 in the forward direction A to clean the vehicle surface 600 to which the handle module 100 is attached.

[0038] like Figure 5 As shown, in some embodiments, the scraper 13 is at least located on the side of the collection port 12 away from the direction of travel A.

[0039] It should be noted that, based on the roller drive component 22 driving the roller body 21 to rotate relative to the handle body 10 along the first rotation direction B, the dirt on the vehicle surface 600, after adhering to the roller, will rotate along the side closer to the forward direction A to the position opposite to the dirt collection port 12 and be scraped off from the roller body 21 by the scraper 13. After being scraped off, it is collected through the dirt collection port 12 into the dirt collection channel 11, making the surface of the roller body 21 clean so that the vehicle surface 600 can continue to be cleaned. Moreover, it avoids the grit on the surface of the roller body 21 from sliding on the vehicle surface 600 and causing damage to the vehicle surface 600, thereby improving the cleaning effect of the handle module 100 and the protection of the vehicle surface 600.

[0040] like Figure 5 As shown, in some embodiments, the handle body 10 is further provided with a dirt collection channel 11, and a dirt collection port 12 is provided opposite to the roller body 21 and communicating with the dirt collection channel 11. The dirt collection channel 11 can be used to collect dirt collected on the roller body 21 through the dirt collection port 12, such as sewage, dust, mud, etc. on the roller body 21.

[0041] It should also be noted that in some embodiments, the handle module 100 is applied to the car wash machine 1000. The base station module 300 in the car wash machine 1000 is connected to the handle module 100 through the pipe module 200. The base station module 300 is provided with a sludge collection box, and the pipe module 200 is provided with a sludge collection pipe (not shown in the figure). One end of the pipe is connected to the sludge collection box, and the other end is connected to the sludge collection channel 11 in the handle module 100. Then, the dirt collected on the roller body 21 can be transferred to the sludge collection box in sequence through the sludge collection port 12, the sludge collection channel 11, and the sludge collection pipe. Furthermore, the car wash machine 1000 also includes a fan module connected to the sludge collection box. The fan module is used to generate a negative pressure source in the sludge collection box 309 to drive the dirt collected on the roller body 21 to be transferred to the sludge collection box in sequence through the sludge collection port 12, the sludge collection channel 11, and the sludge collection pipe. In other embodiments, when the handle module 100 is used alone, the dirt collection channel 11 can also be used to buffer dirt collected on the roller body 21.

[0042] It should be noted that the position of the first nozzle 71 can be set according to the usage requirements of the handle module 100. For example, in some embodiments, the first nozzle 71 is disposed on the handle body 10 and located on the side of the roller body 21 away from the second nozzle 81.

[0043] Specifically, the scraper assembly 90, the second nozzle 81, the roller body 21, and the first nozzle 71 are sequentially arranged on the same side of the handle body 10 along the forward direction A. During the cleaning process of the handheld handle module 100, after the handle module 100 is attached to the target area of ​​the vehicle, it can be pushed in the forward direction A to spray cleaning foam, roll and wash, scrape and clean sewage in the target area, thereby further improving the car wash efficiency and cleaning quality.

[0044] In some embodiments, a scraper 13 extending toward the roller body 21 is also formed at the dirt collection port 12. The scraper 13 is used to scrape off the dirt attached to the roller body 21 to clean the roller body 21. In this embodiment, rinsing the roller body 21 can also improve the cleaning effect of the scraper 13 on the roller body 21. Especially when the roller body 21 has a sponge outer cylinder, the scraper 13 will squeeze out the water absorbed by the sponge outer cylinder during the rotation of the roller body 21 relative to the scraper 13, and take away other dirt attached to the outer periphery of the sponge outer cylinder.

[0045] Furthermore, the cleaning fluid supplied to the second nozzle 81 and the cleaning fluid supplied to the rinsing nozzle 61 can be the same liquid or different liquids. For example, in some embodiments, the cleaning fluid supplied to the second nozzle 81 is clean water, and the cleaning fluid supplied to the rinsing nozzle 61 is a mixture of coating solution and clean water.

[0046] Please see Figure 8 , Figure 8This is a schematic flowchart illustrating a vehicle cleaning method based on a car wash machine, provided in an embodiment of this application. Figure 8 As shown, the vehicle cleaning method based on the car wash machine includes steps S101 and S102.

[0047] Step S101: Control the car wash machine to turn on in order to clean the surface of the car.

[0048] For example, a user can turn on the car wash machine and use the handheld handle module to clean the car's surface.

[0049] Step S102: During the cleaning process of the car surface, the roller drive is controlled to drive the roller body to rotate relative to the handle body in the first rotation direction so as to roll and clean the vehicle surface in contact with the roller body. When the roller body rotates in the first rotation direction, the surface of the roller body on the side closer to the handle module in the forward direction rotates towards the side closer to the handle body. The forward direction is the direction of movement of the handle module when it is held and pushed.

[0050] like Figure 4 As shown, the roller drive unit 22 can be controlled to drive the roller body 21 to rotate relative to the handle body 10 along the first rotation direction B. When the roller body 21 rotates along the first rotation direction B, the surface of the roller body 21 on the side closer to the forward direction A rotates towards the side closer to the handle body 10. This can prevent gravel or other hard dirt adhering to the vehicle surface 600 from sliding on the vehicle surface 600 and causing damage to the vehicle surface.

[0051] In the above embodiment, during the cleaning of the car surface, the roller drive unit is controlled to drive the roller body to rotate relative to the handle body in a first rotation direction to perform rolling cleaning on the vehicle surface in contact with the roller body. When the roller body rotates in the first rotation direction, the surface of the roller body on the side closer to the forward direction of the handle module rotates towards the side closer to the handle body. This allows the sand or other hard dirt on the vehicle surface to be collected after being attached to the roller body and rotated around the side closer to the forward direction during the movement of the handle module on the vehicle surface. This prevents the sand or other hard dirt attached to the vehicle surface from sliding on the vehicle surface and causing damage to the vehicle surface, thereby improving the protection of the vehicle surface and the cleaning effect of the handle module.

[0052] In some embodiments, such as Figure 5As shown, the handle body 10 forms a dirt collection channel 11 with a dirt collection port 12, which is opposite to the roller body 21. The vehicle cleaning method based on a car wash machine provided in this application embodiment further includes: when the roller body rotates along the first rotation direction, controlling the surface of the roller body near the forward direction to rotate towards the side near the dirt collection port, so that the dirt collected on the surface of the roller body can enter the dirt collection channel through the dirt collection port.

[0053] For example, such as Figure 4 and Figure 5 As shown, when the drum body 21 rotates along the first rotation direction B, the surface of the drum body 21 on the side closest to the forward direction can be controlled to rotate towards the side closest to the dirt collection port 12, so that the dirt collected on the surface of the drum body 21 can enter the dirt collection channel 11 through the dirt collection port 12.

[0054] In the above embodiment, when the roller body 21 rotates along the first rotation direction B, by controlling the side surface of the roller body 21 near the forward direction A of the handle module 100 to rotate towards the side near the dirt collection port 12, it can be achieved that during the process of pushing the handle module 100 to move on the vehicle surface, the sand or other hard dirt on the vehicle surface, after being attached to the roller body 21, will rotate around the side near the forward direction to the position opposite to the dirt collection port 12 and be collected. This avoids the sand or other hard dirt attached to the vehicle surface 600 sliding on the vehicle surface 600 and causing damage to the vehicle surface, thereby improving the protection of the vehicle surface 600 and the cleaning effect of the handle module 100.

[0055] In some embodiments, the vehicle cleaning method based on a car wash machine provided in this application further includes: in response to a trigger command of the power button on the handle module, controlling the roller drive to drive the roller body to rotate relative to the handle body in a first rotation direction.

[0056] For example, such as Figure 6 As shown, the power button 41 is located on the side of the handle body 10 away from the roller assembly 20. When the user needs to clean the vehicle surface 600, the user can trigger the power button, causing the roller drive 22 to drive the roller body 21 to rotate relative to the handle body in a first rotation direction to perform rolling cleaning on the vehicle surface 600 in contact with the roller body 21.

[0057] By placing the power button 41 and the roller assembly 20 on opposite sides of the handle body 10, it conforms to ergonomics and makes it convenient for the user to trigger the power button 41 when holding the handle module 100, so that the user can control the rotation and stop of the roller body 21 at any time.

[0058] Please see Figure 9 , Figure 9This is a schematic flowchart illustrating another vehicle cleaning method based on a car wash machine provided in an embodiment of this application. Figure 9 As shown, the vehicle cleaning method based on the car wash machine also includes steps S201 to S203.

[0059] Step S201: When the handle module is close to the car surface, the foam spraying component of the control handle module sprays cleaning foam onto the car surface through the first nozzle.

[0060] like Figures 1 to 4 As shown, specifically, the handle module 100 includes at least a handle body 10, a foam spraying assembly 70, a roller assembly 20, a spray washing assembly 80, and a scraper assembly 90, all of which are mounted on the handle body 10. The foam spraying assembly 70 includes a first nozzle 71 for spraying cleaning foam. The spray washing assembly 80, mounted on the handle body 10, includes a second nozzle 81 for spraying cleaning fluid. The scraper assembly 90 is mounted on the handle body 10. Specifically, the first nozzle 71 sprays cleaning foam supplied by the liquid storage device 501 and transmitted via the pipeline module 502, and the second nozzle 81 sprays cleaning fluid supplied by the liquid storage device 501 and transmitted via the pipeline module 502. The scraper assembly 90, the second nozzle 81, the roller body 21, and the first nozzle 71 are disposed on the handle body 10.

[0061] like Figure 3 As shown, in some embodiments, the scraper assembly 90, the second nozzle 81, the roller body 21, and the first nozzle 71 are sequentially arranged on the same side of the handle body 10 along the forward direction A. It should be noted that, based on the aforementioned cleaning process for the vehicle surface 600, since the scraper assembly 90, the second nozzle 81, and the roller body 21 are sequentially arranged on the same side of the handle body 10 along the forward direction A, during the cleaning process using the handheld handle module 100, after the handle module 100 is attached to the target area of ​​the vehicle, pushing it in the forward direction A allows for the rolling, spraying, scraping, and wastewater removal processes of the target area, greatly improving car washing efficiency and cleaning quality.

[0062] In some embodiments, controlling the spray assembly to spray cleaning foam onto the vehicle surface through a first nozzle may include: controlling the spray assembly to spray cleaning foam onto the vehicle surface through the first nozzle in response to a trigger command on the spray button of the handle module.

[0063] For example, such as Figure 6As shown, the handle module 100 is also provided with a foam spraying button 42. When the foam spraying button 42 is triggered by the user, the foam spraying assembly 70 sprays cleaning foam through the first nozzle 71. In some embodiments, the foam spraying button 42 is located on the side of the handle body 10 away from the roller body 21, so that the user can trigger the foam spraying button 42 when holding the handle module 100, allowing the user to control the foam spraying assembly 70 to spray cleaning foam at any time.

[0064] Step S202: Control the roller drive to drive the roller body to rotate relative to the handle body in the first rotation direction, so as to perform rolling cleaning on the vehicle surface in contact with the roller body.

[0065] For example, after the spray assembly sprays cleaning foam onto the vehicle surface through the first nozzle, the roller drive can be controlled to rotate the roller body relative to the handle body in a first rotation direction to perform rolling cleaning on the vehicle surface in contact with the roller body. This allows grit or other hard dirt on the vehicle surface to be collected and rotated around the side closest to the direction of travel as the handle module moves across the vehicle surface. This prevents the grit or other hard dirt from sliding on the vehicle surface and causing damage, thus improving the protection of the vehicle surface and the cleaning effect of the handle module.

[0066] Step S203: During the process of the spray washing assembly spraying cleaning liquid onto the car surface through the second nozzle, the fan of the car wash machine is controlled to use the suction channel of the scraper assembly to recover the sewage to the collection tank of the car wash machine.

[0067] like Figure 5 , Figure 11 and Figure 12 As shown, in some embodiments, the mounting base body 921 further forms a sewage discharge channel 9211, and the handle body 10 further forms a sewage collection channel 11, and the sewage discharge channel 9211 is connected to the sewage collection channel 11; wherein, the scraper 91 is further provided with at least one sewage suction channel 913, the sewage suction channel 913 having a first sewage suction port 9131 disposed at one end away from the mounting base 92 and a second sewage suction port 9132 disposed at one end close to the mounting base 92, and the second sewage suction port 9132 is connected to the sewage discharge channel 9211 when the scraper 91 is connected to the mounting base 92 through the adapter 911.

[0068] It should be noted that the blower of the car wash machine 1000 is installed in the base station module 300. The base station module 300 also includes a sludge collection tank (not shown in the figure). The sludge collection tank and the sludge collection channel 11 are connected through the pipe module 200. The blower is used to generate negative pressure in the sludge collection tank and the sludge collection channel 11 so that the sewage is sucked into the sludge collection channel 11 through the first suction port 9131, the suction channel 913, the second suction port 9132, and the discharge channel 9211 in sequence, and then transmitted to the sludge collection tank through the pipe module 200.

[0069] In this embodiment, once the scraper assembly successfully adheres to the car surface, the spray washing assembly is automatically controlled to spray cleaning fluid onto the car surface.

[0070] In some implementations, during the process of the spray washing assembly spraying cleaning fluid onto the car surface through the second nozzle, the blower of the car wash machine can be started. The blower rotates rapidly to generate negative pressure, and the wastewater is collected in the collection tank of the car wash machine through the suction channel of the scraper assembly.

[0071] In the above embodiment, during the process of the spray washing assembly spraying cleaning liquid onto the car surface through the second nozzle, the blower of the car wash machine is controlled to utilize the suction channel of the scraper assembly to recover the wastewater to the collection tank of the car wash machine. This can avoid secondary pollution caused by wastewater and also facilitate subsequent wastewater treatment.

[0072] In some embodiments, the handle body is further provided with a sensor that is communicatively connected to the spray washing assembly. When the scraper assembly successfully adheres to the surface of the vehicle, the sensor is triggered and sends a sensing signal to the spray washing assembly so that the second nozzle supplies cleaning fluid.

[0073] In other embodiments, a sensor is triggered when the scraper assembly successfully adheres to the vehicle surface and moves on the vehicle surface. The sensor sends a sensing signal to the spray assembly to cause the second nozzle to supply cleaning fluid.

[0074] For example, the sensing signal can be a high-level signal or a low-level signal.

[0075] like Figures 10 to 12 As shown, in some embodiments, the handle body 10 is further provided with a sensor 18 communicatively connected to the spray washing assembly 80, which is configured to supply cleaning fluid through a second nozzle 81 when the sensor 18 is triggered; wherein, at least one of the scraper 91 and the scraper connector 922 forms a contact portion, and when the scraper portion 912 abuts against a target object having a flat surface and / or an uneven surface, the scraper 91 and the scraper connector 922 deflect relative to the mounting base 92 so that the contact portion triggers the sensor 18.

[0076] For example, when washing a vehicle, when the scraping part 912 of the scraper 91 comes into contact with the irregular curved surface of the vehicle, the flexible scraper 91 and the scraper connector 922 deflect relative to the mounting base 92 to adaptively fine-tune the angle, so that the scraping part 912 of the scraper 91 can maintain sufficient contact with the vehicle surface 600. When in contact with the vehicle surface 600, the sensor 18 is triggered to automatically supply cleaning fluid. When the scraping part 912 of the scraper 91 is not in contact with the vehicle surface 600, the sensor 18 cannot be triggered, that is, the cleaning fluid is no longer supplied.

[0077] In the above embodiments, by setting a sensor to be triggered when the scraper assembly successfully adheres to the car surface, the sensor can send a sensing signal to the spray washing assembly to supply cleaning fluid to the second nozzle. This enables real-time linkage between cleaning fluid spraying and actual cleaning actions. The supply of cleaning fluid is determined by the triggering state of the sensor 18, which can coordinate the spraying of cleaning fluid with cleaning actions such as scraping and brushing. This solves the problem of cleaning fluid spraying too early or too late, and further improves cleaning efficiency.

[0078] In some embodiments, while the spray washing assembly sprays cleaning fluid onto the vehicle surface through the second nozzle, the rinsing assembly of the control handle module supplies cleaning fluid to the roller body through the rinsing nozzle.

[0079] like Figure 5 and Figure 7 As shown, in some embodiments, the handle body 10 is further provided with a liquid supply channel 15, the liquid supply channel 15 having a liquid supply connection port 151, the handle body 10 also includes a rinsing assembly 60, the rinsing assembly 60 including a rinsing nozzle 61 disposed on the handle body 10 and opposite to the roller body 21, and the liquid supply channel 15 is also connected to the rinsing nozzle 61 and the second nozzle 81; wherein, the cleaning liquid input from the liquid supply connection port 151 can be supplied to the second nozzle 81 and / or to the rinsing nozzle 61 through the liquid supply channel 15, so that the rinsing nozzle 61 supplies cleaning liquid to the roller body 21.

[0080] In the above embodiment, during the process of the spray washing assembly spraying cleaning liquid onto the vehicle surface through the second nozzle, the roller body 21 can be made more wet by controlling the rinsing assembly 60 to rinse the roller body 21, thereby improving the cleaning effect of the roller body 21 on the vehicle surface 600.

[0081] In some embodiments, the handle module further includes a balance indicator light; the vehicle cleaning method based on a car wash machine provided in this application embodiment may further include: after detecting that the scraper assembly is successfully attached to the car surface, controlling the balance indicator light to illuminate, so as to indicate that the scraper assembly and the car surface are relatively balanced.

[0082] For example, a sensor can be used to detect whether the scraper assembly is successfully attached to the car surface. For instance, when a sensing signal is received from the sensor, the balance indicator light can be illuminated.

[0083] In the above embodiments, by controlling the balance indicator light to illuminate after the scraper assembly is detected to be successfully attached to the car surface, the user can be prompted to keep the scraper assembly relatively balanced with the car surface and start the cleaning operation, thereby improving the user experience.

[0084] In some embodiments, the handle module further includes a light; the vehicle cleaning method based on a car wash machine provided in this application embodiment may further include: controlling the light to turn on when the light intensity at the location of the car wash machine is less than a preset brightness threshold; or controlling the light to turn on in response to a light-on command.

[0085] It should be noted that, in this embodiment of the application, by adding a light to the handle module, the light can be used for illumination, thereby enriching the functions of the car wash machine.

[0086] For example, a light sensor in the car wash machine can detect the ambient light level at the machine's location. When the ambient light level is lower than a preset brightness threshold, the lights can be turned on. This preset brightness threshold can be set according to actual conditions, and its specific value is not limited here. By controlling the lights to turn on when the ambient light level at the car wash machine's location is detected to be lower than the preset brightness threshold, the lights can be automatically turned on in low-light conditions, making the system more intelligent and user-friendly, and effectively improving the user experience.

[0087] For example, the lights can be turned on by the user pressing the light button on the car wash machine. It should be noted that the user can turn on the lights for illumination according to their actual needs.

[0088] In some embodiments, the cleaning fluid is a coating solution consisting of a coating agent and water; the vehicle cleaning method based on a car wash machine provided in this application may further include: controlling the rinsing assembly to spray the coating solution onto the roller body through the rinsing nozzle, so that the roller body coats the vehicle surface during rotation.

[0089] For example, during or after cleaning a car surface, the rinsing assembly can be controlled to spray a mixture of coating liquid and clean water onto the roller body through rinsing nozzles, so that the roller body coats the vehicle surface during rotation.

[0090] Understandably, diluting the coating agent with water to form a coating solution can not only avoid problems such as uneven application and clumping caused by the viscosity of the original coating agent, but also reduce the consumption of coating agent and lower the cost of use. Furthermore, the film layer is thinner and more uniform after dilution with water, which improves the adhesion to the car paint and enhances the durability of the coating.

[0091] In the above embodiments, by controlling the rinsing assembly to spray the coating liquid onto the roller body through the rinsing nozzle, the roller body can be used to coat the vehicle surface during rotation. This not only improves the coating efficiency but also makes the coating thinner and more uniform, enhances the adhesion between the coating and the paint, and thus improves the coating durability.

[0092] like Figure 13 As shown, in some embodiments, the liquid storage device 501 includes at least a first liquid storage tank 5011 for supplying a first liquid, a second liquid storage tank 5012 for supplying a second liquid, and a third liquid storage tank 5013 for supplying a third liquid. The pipeline module 502 has at least a first flow channel 503, a second flow channel 504, and a third flow channel 505. The first input end of the first flow channel 503 is connected to the first liquid storage tank 5011, the second input end of the first flow channel 503 is connected to the third liquid storage tank 5013, the first input end of the second flow channel 504 is connected to the second liquid storage tank 5012, the second input end of the second flow channel 504 is connected to the third liquid storage tank 5013, and the input end of the third flow channel 505 is connected to the third liquid storage tank 5013.

[0093] The fluid system 500 also includes a power unit 506, which is connected to the pipeline module 502 and is used to provide power for the flow of materials in the pipeline module 502, so that the first liquid and the third liquid are mixed in the first flow channel 503 to form a first target fluid and are output from the output end of the first flow channel 503, and the second liquid and the third liquid are mixed in the second flow channel 504 to form a second target fluid and are output from the output end of the second flow channel 504, and the third liquid is also allowed to pass through the third flow channel 505 and be output from the output end of the third flow channel 505.

[0094] The output end of the first flow channel 503 is connected to the rinsing nozzle 61, the output end of the second flow channel 504 is connected to the first nozzle 71, and the output end of the third flow channel 505 is connected to the second nozzle 81.

[0095] like Figure 13As shown, the power unit 506 includes a first power pump 5061, a second power pump 5062, and a third power pump 5063. The first power pump 5061 is located in the first main pipeline 5021, the second power pump 5062 is located in the second main pipeline 5022, and the third power pump 5063 is located in the third main pipeline 5023. Optionally, one-way valves are provided on the first branch pipeline 5024 and the second branch pipeline 5025. It can be understood that the one-way valves can prevent the fluid from flowing back, ensuring that the liquid in each channel is supplied and mixed independently, and preventing the liquid in the first main pipeline 5021 and the second main pipeline 5022 from flowing back to the third main pipeline 5023, causing disorder in the liquid circuit system 500.

[0096] In this embodiment, the first power pump 5061, the second power pump 5062 and the third power pump 5063 are configured to provide power for liquid flow, ensuring independent mixing and flow of liquid in each channel, with stable power and flexible control.

[0097] As an example, the aforementioned channels and pipes can be used to transport liquids, gases, or mixtures of liquids and gases. In some embodiments, a power unit 506 is disposed within the pipe module 200 to provide power for the flow of materials in the pipeline module 502.

[0098] It is understood that the first liquid, the second liquid, and the third liquid can be selected according to needs, and this application does not impose any restrictions.

[0099] For example, this application embodiment uses the first liquid as a coating agent, the second liquid as a foam concentrate, and the third liquid as water for illustration. Therefore, the user can adjust the handle module 100 according to the cleaning needs to selectively spray water, cleaning foam, or coating liquid from various nozzles. For example, when it is necessary to clean stains and dust on the vehicle surface, water is sprayed from the second nozzle 81; when it is necessary to apply foam for deep cleaning of the vehicle, foam is sprayed from the first nozzle 71; and when coating protection is applied after cleaning, coating liquid is sprayed from the rinsing nozzle 61. Thus, the processes of spraying foam, wiping, rinsing, drying, and coating can be completed in one go, which can effectively improve car washing efficiency and cleaning quality.

[0100] It is understandable that, through the design of the hydraulic system 500, the car wash machine 1000 provided in this application not only integrates multiple washing and care modes such as spraying foam, coating agent, and clean water, but also has simple piping, simple structure, and is lightweight and compact.

[0101] In this embodiment, the liquid circuit system 500 is designed to connect the liquid storage tank and the flow channel and be centrally powered by the power unit 506, enabling independent supply and flexible mixing of multiple liquids. It not only supports the synchronous or separate output of a single liquid (such as a third liquid) and two mixed liquids (i.e., a first target fluid formed by mixing the first liquid and the third liquid, and a second target fluid formed by mixing the second liquid and the third liquid), avoiding cross-interference when different liquids are mixed, and adapting to the usage requirements of diverse scenarios, but also has a simple system structure, reduces pipeline redundancy, and improves the operational stability and maintenance convenience of the liquid circuit system 500.

[0102] like Figures 14 to 16 As shown, in some embodiments, the pipeline module 502 further includes an adapter 507 disposed on the handle module 100. The adapter 507 is provided with at least a first inlet 5071, a second inlet 5072, a third inlet 5073, a first outlet 5075, a second outlet 5076, a third outlet 5077, and a fourth outlet 5078. A channel structure 508 is also formed in the adapter 507 so that the first outlet 5075, the second outlet 5076, and the fourth outlet 5078 are all connected to the first inlet 5071, the first outlet 5075 and the second outlet 5076 are both connected to the second inlet 5072, and the third inlet 5073 is connected to the third outlet 5077.

[0103] The first inlet 5071 is used to introduce the first target gas, the second inlet 5072 is connected to the output end of the first flow channel 503, and the third inlet 5073 is connected to the output end of the second flow channel 504.

[0104] For example, the first target fluid formed by mixing the first liquid and the third liquid flows into the second inlet 5072 through the output end of the first flow channel 503, and the second target fluid formed by mixing the second liquid and the third liquid flows into the third inlet 5073 through the output end of the second flow channel 504. The first target gas introduced through the first inlet 5071 mixes with the first target fluid inside the adapter 507 before being output, achieving bidirectional confluence of the first target gas and the first target fluid. This simplifies the gas-liquid mixing structure and reduces the loss of the first target fluid. Simultaneously, the connection between the third inlet 5073 and the third outlet 5077 ensures the separate output of the second target fluid.

[0105] For example, the first outlet 5075 and the second outlet 5076 are respectively connected to different rinsing nozzles 61, the third outlet 5077 is connected to the first nozzle 71, and the fourth outlet 5078 is connected to the first inlet 5091 of the pipe connector 509. In this way, the coating liquid can be sprayed onto the roller body 21 through different rinsing nozzles 61, foam can be sprayed onto the target object through the first nozzle 71, and clean water can be sprayed onto the target object through the second nozzle 81.

[0106] In this embodiment, the adapter 507 with three inlets and four outlets integrates a multi-channel integrated design, which can realize the separate output of a single fluid (such as a third liquid) and the separate or simultaneous output of two mixed fluids (i.e., a mixture of a first liquid and a third liquid, or a mixture of a second liquid and a third liquid) without additional pipeline splicing. This can greatly simplify the system pipeline layout, reduce the number of components, and reduce costs.

[0107] In some embodiments, the piping module 502 further includes a pipe connector 509 disposed on the handle module 100. The pipe connector 509 includes a first inlet 5091, a second inlet 5092 and a connector outlet 5093, and the connector outlet 5093 is connected to the first inlet 5091 and the second inlet 5092.

[0108] The first inlet 5091 is connected to the fourth outlet 5078 to deliver the first target gas to the connector outlet 5093, the second inlet 5092 is connected to the third liquid storage tank 5013 to deliver the third liquid to the connector outlet 5093, and the connector outlet 5093 is used to deliver the third target fluid, which includes the first target gas and the third liquid.

[0109] In some embodiments, the adapter 507 is used to mix a first target gas into the first target fluid and a third liquid, and to mix a second target gas into the second target fluid. As shown in the figure, the first target fluid flows into the adapter 507 through the first flow channel 503, and is split into the second and third three-way valves via the first three-way valve. Simultaneously, the first target gas, after entering the adapter 507, is conveyed to the second and third three-way valves via the first four-way valve. Finally, the first target fluid mixed with the first target gas is ejected from the first and second sub-nozzles, respectively. The second target fluid flows into the fourth three-way valve of the adapter 507 through the second flow channel 504, and the second target gas also enters through the fourth three-way valve. The second target fluid and the second target gas are mixed through the fourth three-way valve and ejected through the first nozzle 71. As shown in the figure, in some embodiments, the adapter 507 is disposed on the handle module 100.

[0110] like Figures 17 to 22 As shown, in some embodiments, the channel structure 508 includes a first channel component 5081, a second channel component 5082, and a third channel component 5083. The first channel component 5081 includes a first main channel 5084 and a first branch channel 5085 connected to the first main channel 5084. The first main channel 5084 is connected to a first inlet 5071 and is used to deliver a first target gas to the first branch channel 5085. The first branch channel 5085 includes at least a first sub-branch channel 50851, a second sub-branch channel 50852, and a third sub-branch channel 50853.

[0111] The second channel component 5082 includes a second main channel 5087, which is connected to a second inlet 5072 and communicates with a first sub-diversion channel 50851 and a second sub-diversion channel 50852, respectively, to mix the first target fluid and the first target gas within the first sub-diversion channel 50851 and the second sub-diversion channel 50852. The third channel component 5083 includes a third main channel 5088 and a fourth main channel 5089 connected to the third main channel 5088. The third main channel 5088 is connected to the third inlet 5073. Specifically, the first sub-diversion channel 50851 is connected to a first outlet 5075, the second sub-diversion channel 50852 is connected to a second outlet 5076, the fourth main channel 5089 is connected to a third outlet 5077, and the third sub-diversion channel 50853 is connected to a fourth outlet 5078.

[0112] In this embodiment, a channel structure 508 is integrated on an adapter 507, comprising a first channel component 5081, a second channel component 5082, and a third channel component 5083, each corresponding to an inlet and outlet. The first target gas flows in through the first inlet 5071 and is then distributed via the first main channel 5084 of the first channel component 5081 to the first sub-diversion channels 50851, 50852, and 50853, providing a stable gas source for multi-path gas-liquid mixing. The second main channel 5087 is connected to the first and second sub-diversion channels 50851 and 50852, enabling directional mixing of the first target fluid and the first target gas, ensuring mixing uniformity and output stability, and avoiding cross-interference. The third channel component 5083 independently transports the second target fluid, without affecting the gas-liquid mixing channels, thus meeting the need for independent output of multiple fluids.

[0113] In some embodiments, the fourth main channel 5089 is connected to the first channel component 5081 so that a portion of the first target gas flows from the first channel component 5081 to the fourth main channel 5089 so that the second target fluid and the first target gas are mixed in the fourth main channel 5089.

[0114] In this embodiment, a first target gas is introduced into the fourth main channel 5089 through the connection between the fourth main channel 5089 and the first channel component 5081, so that the second target fluid and the first target gas are mixed in the fourth main channel 5089 and then output. It can be understood that when the second liquid is foam concentrate, the third liquid is water, and the second target fluid is a foam liquid formed by mixing the foam concentrate and water, introducing the first target gas into the foam liquid can form foam with stronger cleaning power.

[0115] like Figures 17 to 21As shown, in some embodiments, the second main channel 5087 includes a first sub-branch 50871 and a second sub-branch 50872, and a second inlet 5072 connects the first sub-branch 50871 and the second sub-branch 50872. The first sub-branch 50871 is connected to the first sub-branch channel 50851 and is connected to the second sub-branch 50872 through the second inlet 5072. The second sub-branch 50872 is connected to the second sub-branch channel 50852. When the pipe parameters of the first sub-branch 50871 and the second sub-branch 50872 are the same, the lengths of the first sub-branch 50871 and the second sub-branch 50872 are equal, wherein the pipe parameters include at least the pipe shape and the pipe diameter.

[0116] Alternatively, the second main channel 5087 includes a first sub-channel 50871 and a second sub-channel 50872, and a second inlet 5072 connects the first sub-channel 50871 and the second sub-channel 50872. The first sub-channel 50871 is connected to the first sub-channel 50851 and is connected to the second sub-channel 50872 through the second inlet 5072. The second sub-channel 50872 is connected to the second sub-channel 50852. Furthermore, the first sub-channel 50871 has a curved portion, the second sub-channel 50872 is a straight pipe, and the length of the first sub-channel 50871 is shorter than the length of the second sub-channel 50872.

[0117] It should be noted that factors affecting pipe resistance include at least the pipe shape, pipe diameter, and pipe length. Specifically, the pipe shape includes, for example, whether it is a bend or a straight pipe. It is understandable that a bend changes the direction of fluid flow, generating localized eddies and impacts, resulting in greater resistance than a straight pipe under the same conditions.

[0118] It's also understandable that the smaller the pipe diameter, the larger the frictional contact area during fluid flow, and the higher the resistance is usually. Conversely, the longer the pipe length, the longer the frictional contact time between the fluid and the pipe wall, and the greater the frictional resistance along the way.

[0119] Therefore, to ensure that the same fluid is supplied to two pipelines at opposite ends through a single inlet, and that the fluid velocity or flow rate is the same, it is necessary to compensate for the difference in pipeline resistance by matching pipeline parameters. The pipeline parameters include at least the pipeline shape and the pipe diameter.

[0120] For example, if two pipe segments have the same diameter and are both straight, then the lengths of the two pipe segments must be the same to ensure that the flow velocity and flow rate of the fluid flowing through the two pipe segments are the same. In some specific examples, when two pipe segments have the same diameter, but one segment is straight and the other is bent (e.g., the first sub-branch with the bend is a bend, and the second sub-branch is a branch pipe), since the fluid resistance generated by the bend is greater than that of the straight pipe under the same conditions, the length of the bend should be less than the length of the straight pipe to compensate for the resistance difference between the two pipe segments in order to ensure that the flow velocity and flow rate of the fluid flowing through the bend and the straight pipe are the same.

[0121] In this embodiment, by specifically adjusting the pipe length and shape at both ends of the fluid inlet, the resistance difference between the two pipe sections with the same pipe diameter is offset, ensuring that the fluid output parameters (such as fluid velocity and flow rate) at both ends are consistent, thus meeting the requirements for synchronous operation. This solution eliminates the need for additional complex flow regulating valves and other components, achieving resistance balance solely through optimization of pipe length and shape, ensuring the stability and reliability of fluid delivery, and effectively reducing structural complexity and manufacturing costs. Furthermore, it not only supports the conventional design of two straight pipe sections of equal length but also accommodates combinations of straight and bent pipes, adapting to different installation space requirements.

[0122] Specifically, in some embodiments, the adapter 507 is also provided with a fourth inlet 5074, which is used to introduce a second target gas so that the second target gas and the second target fluid are mixed in the fourth main channel 5089.

[0123] It is understandable that using a single air pump to meet the high flow and high pressure requirements of multi-path air supply would place high demands on the pump's performance and result in significant procurement costs. However, by using dual air pumps instead of a single high-cost air pump, only conventional low-cost air pumps are needed to meet the requirements, significantly reducing equipment procurement costs and thus substantially lowering production costs.

[0124] In this embodiment, in addition to the first inlet 5071 for introducing the first target gas, a fourth inlet 5074 is added to the adapter 507 for introducing the second target gas. This enables dual independent gas supply to adapt to gas-liquid mixing scenarios in different flow channels, making the gas supply more flexible. Moreover, using dual gas pumps instead of a single gas pump can further reduce production costs.

[0125] The embodiments of this application also provide a readable storage medium storing a computer program, which includes program instructions. The processor executes the program instructions to implement any of the vehicle cleaning methods based on a car wash machine provided in the embodiments of this application.

[0126] For example, when the program is loaded by the processor, it can perform the following steps: The car wash machine is turned on to clean the car surface. During the cleaning process, the roller drive is controlled to drive the roller body to rotate relative to the handle body in a first rotation direction to roll and clean the vehicle surface in contact with the roller body. When the roller body rotates in the first rotation direction, the surface of the roller body on the side closer to the handle module in the forward direction rotates towards the side closer to the handle body. The forward direction is the direction of movement of the handle module when it is held and pushed.

[0127] The readable storage medium can be the internal storage unit of the car wash machine in the aforementioned embodiments, such as the hard drive or memory of the car wash machine. The readable storage medium can also be the external storage device of the car wash machine, such as the plug-in hard drive, smart media card (SMC), secure digital card (SDCard), flash card, etc. equipped on the car wash machine.

[0128] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
