Description

Technical Field

[0001] This invention relates to the field of vehicle cleaning technology, and more particularly to a cleaning mechanism for washing and wiping vehicles. Background Technology

[0002] Existing washing and wiping carts typically require lifting the cart during use. Prolonged use results in significant stress on the arm, leading to a poor user experience. Furthermore, frequent stops during the washing and wiping process result in long washing times and low efficiency. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a cleaning mechanism for a wash and scrubber vehicle, which can reduce the weight of the wash and scrubber vehicle and improve the user experience.

[0004] To solve the above-mentioned technical problems, the present invention provides a cleaning mechanism for a washing and wiping vehicle. The cleaning mechanism includes a cleaning component that forms a sealed liquid exchange zone on the surface of the washing and wiping roller. The cleaning component continuously cleans the surface of the washing and wiping roller after the vehicle surface has been washed and wiped, and maintains the humidity of the washing and wiping roller surface. The cleaning component includes a first interference portion that forms a compression with the surface of the washing and wiping roller. The first interference portion has a fixing portion and a sealing portion forming a sealed liquid exchange zone on both sides of the circumferential direction of the washing and wiping roller surface, respectively. A groove is provided between the sealing portion and the fixing portion on the side opposite to the first interference portion.

[0005] Furthermore, a rib is provided between the sealing part and the fixing part on the side opposite to the first interference part.

[0006] Furthermore, when there are multiple ribs, they are arranged in a parallel shape.

[0007] Furthermore, the cleaning mechanism also includes a water-guiding structure that is connected to the sealing part and contacts the surface of the scrubbing roller to form a watertight contact.

[0008] Furthermore, the water-guiding structure includes a water-guiding part that contacts the surface of the washing roller and a water-storing part that is connected to the contact part.

[0009] Furthermore, the water inlet extends into the sealed liquid exchange zone, with the portion of the water inlet near the sealed liquid exchange zone contacting the surface of the washing roller, and a gap being provided between the portion of the water inlet away from the sealed liquid exchange zone and the surface of the washing roller.

[0010] Furthermore, the sealed liquid exchange zone is equipped with a clean water inlet and a wastewater outlet.

[0011] Furthermore, the clean water inlet and the wastewater outlet are located at opposite ends of the sealed liquid exchange zone.

[0012] Furthermore, the sealed liquid exchange zone has an arc-shaped cross-section along its length perpendicular to the horizontal direction.

[0013] Furthermore, the arc shape includes a C-shape.

[0014] Furthermore, the groove has a V-shaped cross-section along its length perpendicular to the surface.

[0015] This invention relates to a cleaning mechanism for a car wash, comprising a cleaning component that forms a sealed liquid exchange zone on the surface of a washing roller. The cleaning component continuously cleans the surface of the washing roller after washing and maintains the surface moisture of the washing roller. The cleaning component includes a first interference portion that forms a pressure against the surface of the washing roller. The first interference portion has a fixing portion and a sealing portion forming the sealed liquid exchange zone on both circumferential sides of the washing roller surface. A groove is provided between the sealing portion and the fixing portion on the side opposite to the first interference portion. Because the cleaning mechanism has a groove between the sealing portion and the fixing portion, the weight of the cleaning mechanism can be reduced, thereby reducing the overall weight and improving the user experience.

[0046] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0047] like Figures 1-8 As shown, the present invention provides an embodiment of a cleaning mechanism for a washing and wiping vehicle.

[0048] like Figure 1 , Figure 2 As shown, the washing and wiping vehicle device equipped with a cleaning mechanism includes a washing and wiping head and a handle (not shown in the figure) connected to the washing and wiping head. The washing and wiping head includes a washing and wiping roller 1 and a cleaning mechanism 2. The washing and wiping roller continuously washes and wips the vehicle surface by continuously rolling on it. The cleaning mechanism continuously cleans the surface of the washing and wiping roller after washing and wiping the vehicle surface and maintains the surface humidity of the washing and wiping roller. It includes a sealed liquid exchange zone A.

[0049] Specifically, such as Figure 1 , Figure 2 As shown, the washing head includes a housing 3 and a washing roller 1 mounted on the housing 3. The surface of the washing roller 1 is provided with a water-absorbing layer, which in this embodiment is a sponge. The washing roller 1 is directly driven by a motor, or it can be driven by a motor or other means through a transmission mechanism. Continuous washing is achieved by the washing roller rolling on the vehicle surface.

[0050] like Figure 2 , Figure 5 As shown, the cleaning mechanism continuously cleans and maintains the surface humidity of the washing roller 1 portion after the vehicle surface has been washed and wiped. It includes a cleaning component, which includes an interference structure component 20 that forms a sealed liquid exchange zone A on the surface of the washing roller 1 portion and squeezes the liquid on the washing roller 1 into the sealed liquid exchange zone A.

[0051] The cleaning mechanism 2 can be an integral structure. Although the following embodiments use multiple parts to implement the cleaning mechanism 2, the component numbers and names mentioned in the following description are consistent with this embodiment. Alternatively, those skilled in the art can make simple modifications and expansions based on the following text description and drawings, all of which are within the protection scope of the technical solution disclosed in this embodiment.

[0052] As a further improved implementation, the cleaning mechanism 2 can also be implemented by multiple parts working together. When multiple separate parts work together, the processing and manufacturing difficulty of the cleaning mechanism can be reduced.

[0053] This embodiment uses the cleaning mechanism 2 as an example of a separate component structure for illustration.

[0054] like Figure 2 , Figure 4 , Figure 5 As shown, the interference structure assembly 20 includes a first interference portion 200 that forms a pressure with the surface of the washing and rubbing roller 1. The first interference portion 200 has a fixing portion 201 and a sealing portion 202 on both sides of the circumferential direction of the washing and rubbing roller 1 surface. The sealing portion 202 extends outward to form a mounting portion 207 with a flat mounting surface for fixing the water-guiding structure 21. The sealing portion 202 and the water-guiding structure 21 cooperate to form a sealed liquid exchange zone A on the surface of the washing and rubbing roller 1. The fixing portion 201 can be fixed to the housing 3. The water-guiding structure 21 can connect with the sealing portion 202 to form a watertight contact on the surface of the washing and rubbing roller 1.

[0055] As a further improved implementation method, such as Figure 4 , Figure 5 , Figure 7 As shown, the first interference portion 200 has arc-shaped protrusions 2001 pointing radially towards the two ends near the housing 3 along the length direction of the washing roller 1. The portion of the arc-shaped protrusion closer to the two ends of the housing has a larger interference with the washing roller 1. This ensures that even if there is slight misalignment during the high-speed rotation of the washing roller 1, liquid leakage from both ends of the housing 3 will not occur due to insufficient interference between the washing roller and the first interference portion. The arc-shaped protrusion 2001 is offset from the axial direction of the washing roller 1, and the arc can be gradually changed along or against the direction of rotation of the washing roller 1.

[0056] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the water-guiding structure 21 includes a water-guiding part 211 in contact with the surface of the washing and rubbing roller 1, a water-storing part 214 connected to the water-guiding part, guide strips 212 that cause interference between the two ends of the washing and rubbing roller 1, and an extension part 210 with a first gap B1 between it and the surface of the washing and rubbing roller 1. The circumferential end of the water-guiding part 211 is provided with a second interference part 2111 that forms a water seal with the surface of the washing and rubbing roller 1. Guide strips 212 that cause interference between the two ends of the washing and rubbing roller 1 are provided at both ends of the length direction of the water-guiding part 211, that is, the guide strips 212 are in partial contact with the surface of the washing and rubbing roller 1. The inner side of the guide strip 212 is provided with an inclined surface 2121. The inclined surface 2121 has an arc-shaped structure. The arc-shaped structure design of the inclined surface 2121 can keep the contact pressure of each part when the inclined surface contacts the surface of the washing and rubbing roller 1 basically the same. The guide strip 212 extends towards the sealed liquid exchange zone A with protrusions 2122. These protrusions 2122, together with the first interference portion 200, the second interference portion 2111, the water storage portion 214, and the sealing portion 202, enclose the sealed liquid exchange zone A near the two ends of the washing roller 1 on both sides of the sealed liquid exchange zone A. The water storage portion 214, the water intake portion 211, the guide strip 212, and the sealing portion 202 cooperate with the surface of the washing roller 1 to form a complete sealed liquid exchange zone A. The extension portion 210 and the water intake portion 211 are located on both sides of the water storage portion 214. The water storage portion 214 and the sealing portion 202 are fixed by a waterproof connection.

[0057] As a further improved implementation, the second interference part 2111 can adopt a strip structure, and the contact surface formed between it and the surface of the washing and rubbing roller 1 is as small as possible. This can ensure that no leakage occurs from the second interference part 2111 during the water exchange process, while also reducing the rotational resistance of the washing and rubbing roller 1 during operation. In addition, it can effectively increase the gap length in the circumferential direction of the washing and rubbing roller 1, thereby increasing the pressure relief area.

[0058] As a further improved implementation method, such as Figure 10 , Figure 11 As shown, the water-guiding structure 21 includes a water-guiding part 211 that contacts the surface of the washing and rubbing roller 1, a water-storing part 214 connected to the water-guiding part 211, and an extension part 210 with a first gap B1 between it and the surface of the washing and rubbing roller 1. The circumferential end of the water-guiding part 211 is provided with a second interference part 2111 that forms a watertight contact with the surface of the washing and rubbing roller 1. The water-guiding part 211 extends all the way to the end of the housing 3 where the washing and rubbing roller 1 is clamped between the upper and lower parts of the housing. This eliminates the need for the complex structure of guide strips 212 that extend at both ends of the length of the water-guiding part 211 to cause interference between the surfaces of the two ends of the washing and rubbing roller 1. This implementation can reduce the processing and manufacturing difficulty of the water-guiding structure 21.

[0059] like Figure 2 , Figure 3 As shown, the cleaning mechanism 2 also includes a first fixing member 22 and a second fixing member 23 that cooperate with the sealing part 202 to fix the water-guiding structure 21. The first fixing member 22 needs to be fixed by the second fixing member 23. The surface of the first fixing member 22 near the washing roller 1 is set with an arc-shaped structure, and there is a second gap B2 between the arc-shaped structure and the surface of the washing roller 1 that communicates with the first gap B1. The first gap B1 and the second gap B2 form a pressure relief chamber B. Since the first gap B1 and the second gap B2 form a relatively large area projection on the surface of the washing roller 1, when pressure needs to be relieved, the pressure relief outlet 27 is connected to the pressure relief chamber B through a solenoid valve (not shown in the figure), which can be absorbed by the washing roller 1 more quickly, thereby avoiding the phenomenon of bubbles when the pressure is released to the washing roller 1.

[0060] As a further improved implementation method, such as Figure 11 As shown, the first fixing member 22 is an integral structure, which can further simplify the internal structure of the cleaning mechanism 2 and reduce the processing and manufacturing difficulty of the cleaning mechanism.

[0061] As a further improved implementation method, such as Figure 2 , Figure 4 As shown, the pressure relief outlet 27 is directly connected to the pressure relief chamber B, which can further simplify the internal structure of the cleaning mechanism 2 and reduce the processing and manufacturing difficulty of the cleaning mechanism.

[0062] As a further improved implementation method, as needed, such as Figure 4 , Figure 5 As shown, the cleaning mechanism 2 also includes a third interference portion 231 formed on the surface of the washing roller 1 by the second fixing member 23. This third interference portion 231 can be a strip-shaped structure. The third interference portion 231 can be disposed on the first fixing member 22 or on other components. For example, when the first fixing member 22 needs to be fixed by the second fixing member 23, the third interference portion 231 can be disposed on the second fixing member 23. The third interference portion 231, the water-guiding portion 211, the second interference portion 2111, and the guide strip 212 form a closed pressure relief chamber B, preventing bubbles from appearing on the surface of the washing roller 1 when the pressure is high.

[0063] like Figure 5As shown, the third interference portion 231 includes an outer side 2311 of the third interference portion located on the outer side when viewed from the direction of the clockwise rotating washing roller 1, and an inner side 2312 of the third interference portion located on the inner side when viewed from the direction of the clockwise rotating washing roller 1. Since the third interference portion 231 is located closest to the vehicle surface, when particulate debris is present, it can be separated from the surface of the washing roller 1 by the action of the third interference portion 231, and aggregated on the inner side 2312 of the third interference portion. When the third interference portion 231 is located on the second fixing member 23, it can be easily removed for cleaning.

[0064] As a further improved implementation, the third interference part 231 can be disposed on other components as needed, and can be easily removed for cleaning.

[0065] like Figure 2 , Figure 5 As shown, the sealing part 202 forms a groove (not shown in the figure) between the sealing part 202 and the fixing part 201 on the side opposite to the first interference part 200. The groove has a V-shaped cross-section along its length perpendicular to the surface. To improve the strength and stability of the sealing part 202, a rib 203 is provided between the sealing part 202 and the fixing part 201 on the side opposite to the first interference part 200. When there are multiple ribs 203, they are arranged in a parallel shape.

[0066] like Figures 2 to 5 As shown, the cleaning mechanism 2 further includes a water-guiding structure 21 that is connected to the sealing part 202 and forms a watertight contact with the surface of the scrubbing roller 1. The water-guiding structure 21 includes a water-guiding part 211 that contacts the surface of the scrubbing roller 1 and a water storage part 214 connected to the water-guiding part, as well as an extension part 210 that has a pressure relief chamber B between it and the surface of the scrubbing roller 1. The pressure relief chamber B is connected to the pressure relief outlet 27.

[0067] As a further improved implementation method, as needed, such as Figure 3 As shown, a pressure-relieving chamber 220 is provided between the pressure relief chamber B and the pressure chamber (not shown in the attached figure, which may be one of the inner cavities of the container for collecting, filtering, and outputting return water from the washing and wiping vehicle device). A pressure relief hole 222 is provided between the pressure-relieving chamber 220 and the pressure relief chamber B. The surface area of ​​the washing and wiping roller 1 forming part of the pressure relief chamber B is larger than the surface area of ​​the washing and wiping roller 1 forming part of the sealed liquid exchange zone A. Because the surface area of ​​the squeezing washing and wiping roller 1 is smaller, the air generated is limited, while the area of ​​the pressure relief chamber B is larger, making pressure relief easier.

[0068] like Figure 2 , Figure 3As shown, the water inlet 211 extends into the sealed liquid exchange zone A. The portion of the water inlet near the sealed liquid exchange zone A contacts the surface 1 of the washing roller, while a gap B1 is provided between the portion of the water inlet away from the sealed liquid exchange zone A and the surface of the washing roller 1. The sealed liquid exchange zone has an arc-shaped cross-section along its length perpendicular to the horizontal direction, including a C-shape.

[0069] As a further improved implementation method, as needed, such as Figure 2 , Figure 5 As shown, the first interference part 200 has protrusions 201 at both ends. The extrusion force formed by the protrusions 201 on the surface of the washing roller 1 is less than or equal to that of the first interference part 200. The protrusions 201 can prevent the liquid on both sides of the washing roller 1 from seeping outward when squeezing water.

[0070] As a further improved implementation method, as needed, such as Figure 2 , Figure 5 As shown, the protrusion 201 is not on the same straight line as the first interference portion 200 in the length direction. It is best to extend into the sealed liquid exchange zone A so that the squeezed liquid can be gathered in the middle and prevent leakage from both sides.

[0071] like Figure 5 , Figure 6 As shown, the straight portion 216 of the water-guiding structure 21 has several through holes (not shown in the figure), and the top of the first fixing member 22 has several nut posts (not shown in the figure). The nut posts mate with the through holes. Then, by driving the fastening screws down through the mounting portion 207 of the interference structure assembly 20 through the top of the straight portion 216 of the water-guiding structure 21, the fastening screws can be driven into the nut posts on the top of the first fixing member 22, thereby realizing the installation of the main component of the cleaning mechanism 2. Furthermore, the second fixing member 23 can be detachably connected to the first fixing member 22 by an interference fit through an opening at the bottom of the first fixing member 22 (not shown in the figure). To facilitate disassembly and assembly, a gap 221 is left between the second fixing member 23 and the first fixing member 22 so that the compressed air during the interference fit insertion process still has some space, improving the convenience of disassembly and assembly.

[0072] like Figure 6 , Figure 7As shown, in the middle of the cleaning mechanism 2 assembled by the water-guiding structure 21, the first fixing member 22, and the second fixing member 23, there is a pressure relief port 222 communicating with the air outlet 27. The main body of the pressure relief port 222 communicating with the air outlet 27 is located in the middle of the first fixing member 22. The side of the first fixing member 22 facing the surface of the washing and rubbing roller 1 is an arc surface 223 with a similar curvature. The arc surface 223, the pressure relief port 222, and the surface of the washing and rubbing roller 1 together form a second gap B2. The upper half of the pressure relief port 222 (not shown in the figure) is located in the middle of the water-guiding structure 21, and the lower half of the pressure relief port 222 (not shown in the figure) is located in the middle of the second fixing member 23. The two upper and lower half guide portions together form a complete guide portion of the pressure relief port 222 (not shown in the figure). The guide portion of the pressure relief port 222 can increase the air outlet area of ​​the pressure relief port 222, further reduce the air outlet velocity, and at the same time make it more conducive to the exhaust air being evenly dispersed on the surface of the washing and wiping roller 1, further reducing the noise generated by the washing and wiping vehicle device during the pressure relief and exhaust process.

[0073] As a further improved implementation method, as needed, such as Figure 8 As shown, an exhaust pipe interface seat 35 for connecting a pressure relief pipeline (not shown in the attached figure) is provided in the middle of the side of the first fixing member 22 facing away from the washing roller 1. The exhaust pipe interface seat has an air outlet 27 inside. When it is necessary to release the pressure accumulated inside the car washing device, the pressure relief pipeline discharges air to the pressure relief chamber B through the air outlet 27 in the exhaust pipe interface seat 35. The pressure relief chamber B further releases the accumulated pressure, thereby realizing the release of the pressure accumulated inside the car washing device.

[0074] like Figure 8 As shown, combined with Figure 2 To ensure continuous exchange of fluids in the sealed fluid exchange zone A during operation, the zone can be equipped with a clean water inlet A1 connected to the outlet pipe 41 and a wastewater outlet A2 connected to the return water inlet 51. The clean water inlet can be connected to the cleaning fluid container (not shown in the attached diagram) via a water pump (not shown in the diagram), and the wastewater outlet can also be connected to the wastewater container (not shown in the attached diagram) via a water pump. A conversion device (not shown in the attached diagram) can be provided between the wastewater container and the cleaning fluid container to convert wastewater into cleaning fluid, thus protecting the vehicle from continuous washing over extended periods. The cleaning fluid can include clean water, a mixture of clean water and cleaning fluid, or only cleaning fluid. The cleaning fluid inlet A1 and the wastewater outlet A2 are located at opposite ends of the sealed fluid exchange zone A.

[0075] As a further improved implementation, as needed, in the above embodiments, the cross-section of the first interference part 200 can be triangular, and the top of the three angles is a smooth arc structure. This can reduce the resistance generated by the large contact surface during interference, and at the same time reduce the frictional wear on the washing roller 1, and extend its service life.

[0076] As a further improved implementation method, as needed, such as Figure 7 , Figure 9 As shown, the second fixing member 23 extends A-shaped water-collecting protrusions 234 at both ends of the third interference portion 231 along the length direction and simultaneously radially upward along the outer surface of the washing and scrubbing roller 1. The second fixing member 23 continues to extend towards both ends at the water-collecting protrusions 234, while the interference fit between it and the outer surface of the washing and scrubbing roller 1 gradually decreases to zero until a gap is left between them, forming a collapsed section 232. The second fixing member 23 has a slight interference fit with the outer surface of the washing and scrubbing roller 1 at the third interference portion 231 and the two water-collecting protrusions 234, forming a fine particulate waste collection space G at the lower part of the second gap B2 for holding fine particulate waste. On one hand, the outer side 2311 of the third interference section 231 is closest to the vehicle surface. When particulate waste is present, it can be separated from the surface of the scrubbing roller 1 by the action of the outer side 2311 of the third interference section. When the particulate waste is adhered to the highest point of the third interference section 231 by the adhesive action of the water-absorbing layer 11 on the surface of the wetted scrubbing roller 1, under the impact of the vented air released through the air outlet 27, and accompanied by the water-absorbing layer 11 being wetted again by the sewage squeezed out by the first interference section 200, the particulate waste forms a deposit on the concave side 2312 of the third interference section. When the third interference section 231 is located on the second fixing member 23, it can be easily removed, thereby facilitating the cleaning of the particulate waste deposited in the fine particulate waste collection space G. On the other hand, when the vented air is released into the pressure relief chamber B through the air outlet 27 and encounters the fine particulate waste collection space G filled with particulate waste or sewage, the first exhaust gap D1 and the second exhaust gap D2 are formed because there is a gap between the collapsed section 232 of the second fixing member 23 and the water-absorbing layer 11 on the surface of the washing roller 1. After encountering the obstruction of the fine particulate waste collection space G, the vented air will be discharged from the first exhaust gap D1 and the second exhaust gap D2 to the outside of the car washing device, thereby releasing the pressure accumulated inside the car washing device.
