Description

Technical Field

[0001] This invention relates to the field of vehicle cleaning technology, and in particular to an ultra-thin end plate with built-in water channels and a vehicle washing and wiping device. Background Technology

[0002] Vehicles require regular washing; otherwise, dust easily accumulates on their surfaces, affecting their appearance. Currently, vehicles are cleaned in two ways: one is through professional car detailing shops, and the other is by the user using specialized tools. The former has drawbacks: it requires moving the vehicle to a detailing shop, takes a long time, is expensive, and uses a lot of water, which is not environmentally friendly. The latter, while cheaper, uses a significant amount of water, leading to waste, and is also more labor-intensive and prone to incomplete cleaning, failing to achieve the desired results.

[0003] Existing car washing devices typically require separate wiping and cleaning, resulting in poor wiping efficiency. Chinese Patent CN201320487810.5 discloses a miniature portable car washing machine. Its structure includes an operating handle at one end of the frame and a soft-bristled brush roller at the other. The soft-bristled brush roller is connected to a brush roller motor inside the frame via a synchronous belt. A cloth-collecting roller motor is connected to a cloth-collecting roller via a synchronous belt. The cloth-collecting roller drives a coarse wiping roller, a cloth-positioning roller, a fine wiping roller, and a cloth-feeding roller via the wiping cloth. These rollers are all shaft-connected within the frame. While this solution saves water compared to traditional car washing methods and allows for simultaneous wiping and washing, the inclusion of the soft-bristled brush roller, cloth-collecting roller, and related drive mechanisms makes the entire car washing machine less convenient to use. Furthermore, the large number of rotating parts makes operation and maintenance inconvenient. (See the attached specification of this patent.) Figure 2 The axial dimensions of the soft brush roller, coarse scrubbing roller, and fine scrubbing roller shown are not a large proportion of the width of the entire car wash machine. This means that under the same size constraints, it is necessary to travel more paths and distances to clean the same area, resulting in low scrubbing efficiency. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide an ultra-thin end plate with a built-in water channel. The through holes and related water channels inside the ultra-thin end plate facilitate the rotation of the washing and wiping roller while also providing cleaning fluid to clean the washing and wiping roller. The axial thickness of the washing and wiping roller is very thin, which further increases the proportion of the axial dimension of the washing and wiping roller to the width of the entire washing and wiping vehicle device, thereby achieving the effect of increasing the width of a single washing and wiping operation while maintaining the same width of the washing and wiping vehicle device.

[0005] To address the aforementioned technical problems, in a first aspect, the present invention provides an ultra-thin end plate with a built-in water channel, comprising an upper end portion and a lower end portion extending from the housing body of a washing and wiping vehicle device. The upper and lower end portions of the housing elastically clamp the washing and wiping rollers of the washing and wiping vehicle device. The through holes and related water channels within both end portions facilitate the rotation of the washing and wiping rollers while simultaneously providing cleaning fluid to clean them.

[0006] The washing and wiping roller achieves continuous washing and wiping by continuously rolling on the vehicle surface;

[0007] The water channel continuously cleans the surface of the washing roller after the vehicle surface has been washed and maintains the surface humidity of the washing roller. It includes a clean water side channel and a wastewater side channel.

[0008] Furthermore, the upper part of the housing includes an upper end shell and an upper end bottom shell, wherein the upper end bottom shell extends from the housing body and is integrally formed with the housing body, and the upper end shell is detachably connected to the upper end bottom shell. The lower part of the housing includes a lower end shell and a lower end bottom shell, wherein the lower end bottom shell extends from the housing body and is integrally formed with the housing body, and the lower end shell is detachably connected to the lower end bottom shell.

[0009] Furthermore, the inner side of the upper bottom shell of the housing facing the snap-fit ​​washing and wiping roller is provided with a clean water channel. One end of the clean water channel is connected to a clean water inlet, and the other end is connected to a clean water side channel outlet. The clean water inlet, the clean water channel, and the clean water side channel outlet form the clean water side channel built into the upper bottom shell of the housing.

[0010] Furthermore, the upper bottom shell of the housing is provided with a washing and wiping roller engaging hole for engaging the end button of the washing and wiping roller.

[0011] Furthermore, the inner side of the bottom shell of the upper end of the housing that engages with the washing and wiping roller is provided with a step for the washing and wiping roller to slide out.

[0012] Furthermore, the upper bottom shell of the shell is provided with multiple reinforcing ribs in the thickness direction that radiate around the central area, and several transverse reinforcing ribs in the shape of a racetrack are also provided perpendicular to the radial reinforcing ribs.

[0013] Furthermore, the lower end of the housing has a sewage channel on the inner side of the bottom shell facing the snap-on washing roller. One end of the sewage channel is connected to the sewage collection port, and the other end is connected to the sewage side channel outlet. The sewage collection port, the sewage channel, and the sewage side channel outlet form the sewage side channel built into the upper end of the housing.

[0014] Furthermore, the outline of the projection of the clean water side channel outlet onto the inner side of the lower end of the shell falls within the outline of the projection of the sewage collection port onto the inner side of the lower end of the shell, and the outline of the projection of the clean water inlet onto the inner side of the lower end of the shell partially intersects with the outline of the projection of the sewage side channel outlet onto the inner side of the lower end of the shell.

[0015] Furthermore, the lower end of the housing has two wire holes on the outer side of the bottom shell facing away from the snap-fit ​​washing roller for inserting and exiting the motor power cable, and the two holes are connected by a wire through groove.

[0016] Secondly, the present invention also provides a vehicle washing and wiping device, including a washing and wiping head and a handle connected to the washing and wiping head. The washing and wiping head includes a washing and wiping roller, a cleaning mechanism, a housing body, and a motor sleeved inside the washing and wiping roller. The housing body clamps the two ends of the washing and wiping roller, which extend with ultra-thin end plates as described in the first aspect, wherein the washing and wiping roller achieves continuous washing and wiping by continuously rolling on the vehicle surface; 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, and includes a sealed liquid exchange zone formed with the surface of the washing and wiping roller.

[0017] Furthermore, the cleaning mechanism 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 on both sides of the circumferential direction of the washing and wiping roller surface, and the sealing portion forms a sealed liquid exchange zone on the surface of the washing and wiping roller.

[0018] Furthermore, a V-shaped groove is formed between the sealing part and the fixing part on the side opposite to the first interference part, and a rib is provided between the sealing part and the fixing part on the side opposite to the first interference part.

[0019] 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. The water-guiding structure includes a water-guiding part that contacts the surface of the scrubbing roller and a water-storing part that is connected to the contact part.

[0020] Furthermore, the water-guiding structure is provided with guide strips at both ends that partially contact the surface of the washing and wiping roller.

[0021] Furthermore, the sealed liquid exchange area is provided with a clean water inlet and a wastewater outlet, which are located at both ends of the sealed liquid exchange area and connected to the ultra-thin end plate of the built-in water circuit.

[0022] Furthermore, the sealed liquid exchange zone has an arc-shaped cross-section along its length perpendicular to the horizontal direction.

[0023] The present invention relates to an ultra-thin end plate with a built-in water channel, comprising an upper end and a lower end of the housing extending from the housing body of the washing and wiping vehicle device. The upper and lower ends of the housing elastically clamp the washing and wiping roller of the washing and wiping vehicle device. The through holes and related water channels inside both facilitate the rotation of the washing and wiping roller while simultaneously providing cleaning fluid to clean it. The washing and wiping roller achieves continuous washing and wiping by continuously rolling on the vehicle surface. The water channels continuously clean the surface of the washing and wiping roller after washing and wiping the vehicle surface and maintain the surface humidity of the washing and wiping roller. These channels include a clean water side channel and a wastewater side channel, further increasing the proportion of the axial dimension of the washing and wiping roller to the width of the entire washing and wiping vehicle device, thus achieving the effect of a small washing and wiping vehicle device with a large single-wash width dimension.

[0024] This invention relates to a vehicle washing and wiping device, comprising a washing and wiping head and a handle connected to the washing and wiping head. The washing and wiping head includes a washing and wiping roller, a cleaning mechanism, a housing body, and a motor fitted inside the washing and wiping roller. The housing body holds the washing and wiping roller at both ends, with ultra-thin end plates extending from both ends to form built-in water channels. The washing and wiping roller achieves continuous washing and wiping by continuously rolling on the vehicle surface. 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, including forming a sealed liquid exchange zone with the surface of the washing and wiping roller. In use, dust and other contaminants are removed from the washing and wiping roller by continuously squeezing out water, while clean water injected into the sealed liquid exchange zone dilutes the wastewater, thus maintaining a certain level of humidity on the washing and wiping roller for continuous washing. Because the cleaning mechanism has a sealed liquid exchange zone, no cleaning liquid will leak out in any direction during use, thus better adapting to various conditions during vehicle washing and wiping and avoiding stains left after continuous wiping. Furthermore, since this vehicle washing and wiping device is equipped with only one rotating part, its ease of use and maintenance is improved. Attached Figure Description

[0059] The technical solution of the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of the present invention.

[0060] It should be understood that, in the description of the embodiments of the present invention, all directional indicating terms, such as "up," "down," "left," "right," "front," and "back," indicate the orientation or positional relationship based on the orientation and positional relationship shown in the accompanying drawings or the orientation or positional relationship commonly used when the product is in use. These terms are merely for the purpose of simplifying the description of the present invention and do not explicitly or implicitly suggest that the device, element, or component referred to must have a specific orientation or specific orientational structure, and should not be construed as a limitation of the present invention. They are only used to explain the relative positional relationships and movements between the components shown in the accompanying drawings. When this specific orientation changes, the directional indication may also change accordingly.

[0061] Furthermore, in this invention, ordinal numbers such as "first" and "second" are used for distinguishing purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Thus, the features referred to as "first" and "second" may explicitly or implicitly include at least one of those technical features.

[0062] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," and "screw-in" should be interpreted broadly. For example, they can refer to a relatively fixed positional relationship between components, or a physically fixed connection between components; they can be detachable connections or integral structures; they can be mechanical connections or electrical signal connections; they can be direct connections or indirect connections through intermediate media or components; they can refer to the internal communication of two elements or the interaction between two elements. Unless otherwise explicitly limited in the specification, other interpretations will not achieve the corresponding functions or effects. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0063] If the controllers or control circuits involved in this invention are conventional control technologies or units for those skilled in the art, such as the control circuits of the controllers, they can be implemented by those skilled in the art using existing methods, such as simple programming.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0065] 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.

[0066] like Figures 1-7 As shown, the present invention provides an embodiment of an ultra-thin end plate with a built-in water channel and a washing and wiping vehicle device configured therewith.

[0067] like Figure 1 , Figure 2 As shown, the washing and wiping vehicle device with an ultra-thin end plate with a built-in water channel 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 1 continuously washes and wips the vehicle surface by continuously rolling on it. The cleaning mechanism 2 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 area A.

[0068] 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 (not shown in the figure), which in this embodiment is a sponge. The washing roller 1 is directly driven by a motor (not shown in the figure), or it can be driven by a motor or the like through a transmission mechanism (not shown in the figure). Continuous washing is achieved by the washing roller rolling on the vehicle surface.

[0069] like Figure 2 As shown, the cleaning mechanism continuously cleans and maintains the humidity of the washing roller 1 portion surface after washing and wiping the vehicle surface. It 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.

[0070] The cleaning mechanism 2 adopts an integral structure. Although the following embodiments use the cleaning mechanism 2 as multiple parts, the component numbers and names involved 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.

[0071] 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.

[0072] This embodiment uses the cleaning mechanism 2 as an example of a separate component structure for illustration.

[0073] like Figure 2 , Figure 3 As shown, the interference structure assembly 20 includes a first interference portion 20A that forms a compression with the surface of the washing and rubbing roller 1. The first interference portion 20A has a fixing portion 21 and a sealing portion 22 on both sides of the circumferential direction of the washing and rubbing roller 1 surface. The sealing portion 22 cooperates with the water-guiding structure 41 to form a sealed liquid exchange zone A on the surface of the washing and rubbing roller 1. The fixing portion 21 can be fixed to the housing 3. The water-guiding structure 41 can connect with the sealing portion 22 to form a water-sealed contact on the surface of the washing and rubbing roller 1.

[0074] As a further improved implementation method, such as Figure 3 , Figure 4 As shown, the first interference portion 20A has arc-shaped protrusions (not shown in the figure) pointing radially towards both ends of the washing roller 1 near the housing 3 along the length of the washing roller 1. The portion of the arc-shaped protrusion closer to the 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 deviates 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.

[0075] like Figure 3As shown, the water-guiding structure 41 includes a water-guiding part 411 in contact with the surface of the washing and rubbing roller 1, a water-storing part 414 connected to the water-guiding part, guide strips 412 that cause interference between the two ends of the washing and rubbing roller 1, and an extension part 410 with a first gap (not shown in the figure) between it and the surface of the washing and rubbing roller 1. The circumferential end of the water-guiding part 411 is provided with a second interference part (not shown in the figure) that forms a watertight contact with the surface of the washing and rubbing roller 1. Guide strips 412 that cause interference between the two ends of the washing and rubbing roller 1 are respectively provided at both ends of the length direction of the water-guiding part 411, that is, the guide strips 412 are in partial contact with the surface of the washing and rubbing roller 1. The inner side of the guide strip 412 is provided with an inclined surface (not shown in the figure). The inclined surface is an arc-shaped structure. The arc-shaped structure design of the inclined surface 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 412 extends towards the sealed liquid exchange zone A with a protrusion (not shown in the attached figure). This protrusion, together with the first interference portion 20A, the second interference portion, the water storage portion 414, and the sealing portion 22 on both sides of the sealed liquid exchange zone A, surrounds the surface of the washing roller 1 to form a sealed liquid exchange zone A. The water storage portion 414, the water intake portion 411, the guide strip 412, and the sealing portion 22 cooperate with the surface of the washing roller 1 to form the sealed liquid exchange zone A. The extension portion 410 and the water intake portion 411 are located on both sides of the water storage portion 414. The water storage portion 414 and the sealing portion 22 are fixed by a waterproof connection.

[0076] As a further improved implementation, the second interference part 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 during water exchange, 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.

[0077] like Figure 2 , Figure 3 As shown, the cleaning mechanism 2 also includes a first fixing member 42 and a second fixing member 43 that cooperate with the sealing part 22 to fix the water-guiding structure 41. The first fixing member 42 needs to be fixed by the second fixing member 43. The surface of the first fixing member 42 near the washing and rubbing roller 1 is set with an arc-shaped structure, and there is a second gap (not shown in the figure) between the arc-shaped structure and the surface of the washing and rubbing roller 1 that communicates with the first gap. The first gap and the second gap form a pressure relief chamber (not shown in the figure). Since the first gap and the second gap form a large area projection on the surface of the washing and rubbing roller 1, when pressure relief is required, the pressure relief outlet (not shown in the figure) is connected to the pressure relief chamber through a solenoid valve (not shown in the figure), which can be absorbed by the washing and rubbing roller 1 more quickly, thereby avoiding the phenomenon of bubbles when the pressure is released to the washing and rubbing roller 1.

[0078] As a further improved implementation method, such as Figure 2 , Figure 3As shown, the first fixing member 42 can also be 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.

[0079] As a further improved implementation method, such as Figure 2 , Figure 3 As shown, the pressure relief outlet is directly connected to the pressure relief chamber, which can further simplify the internal structure of the cleaning mechanism 2 and reduce the processing and manufacturing difficulty of the cleaning mechanism.

[0080] As a further improved implementation method, as needed, such as Figure 2 , Figure 3 As shown, the cleaning mechanism 2 also includes a third interference portion (not shown in the figure) formed on the surface of the washing roller 1 by the second fixing member 43. This third interference portion can be a strip-shaped structure. The third interference portion can be disposed on the first fixing member 42 or on other components. For example, when the first fixing member 42 needs to be fixed by the second fixing member 43, the third interference portion can be disposed on the second fixing member 43. The third interference portion, the water guiding portion 411, the second interference portion, and the guide strip 412 form a closed pressure relief chamber, preventing bubbles from appearing on the surface of the washing roller 1 when the pressure is high.

[0081] As a further improved implementation, the third interference part can be disposed on other components as needed, and can be easily removed for cleaning.

[0082] like Figure 2 , Figure 3 As shown, the sealing part 22 forms a V-shaped groove (not shown in the figure) between the sealing part 22 and the fixing part 21 on the side opposite to the first interference part 20A. In order to improve strength and reduce weight, a rib 23 is provided between the sealing part 22 and the fixing part 21 on the side opposite to the first interference part 20A.

[0083] like Figure 2 , Figure 3 As shown, the cleaning mechanism 2 further includes a water-guiding structure 41 that is connected to the sealing part 22 and forms a watertight contact with the surface of the washing and wiping roller 1. The water-guiding structure 41 includes a water-guiding part 411 that contacts the surface of the washing and wiping roller 1 and a water storage part 414 connected to the water-guiding part, as well as an extension part 410 that has a pressure relief chamber between it and the surface of the washing and wiping roller 1, the pressure relief chamber being connected to a pressure relief outlet.

[0084] like Figure 2 , Figure 3As shown, the water inlet 211 extends into the sealed liquid exchange zone A. The portion of the water inlet 211 near the sealed liquid exchange zone A contacts the surface 1 of the washing roller, while a gap is provided between the portion of the water inlet 211 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, and this arc shape includes a C-shape.

[0085] As a further improved implementation method, as needed, such as Figure 3 As shown, the first interference part 20A has protrusions at both ends (not shown in the figure). The extrusion force formed by the protrusion on the surface of the washing and rubbing roller 1 is less than or equal to that of the first interference part 20A. The protrusion can prevent the liquid on both sides of the washing and rubbing roller 1 from seeping outward during squeezing.

[0086] As a further improved implementation method, as needed, such as Figure 3 , Figure 4 As shown, the protrusion is not on the same straight line as the first interference portion 20A in the length direction. It is best to extend into the sealed liquid exchange area A so that the squeezed liquid can be gathered in the middle and prevent leakage from both sides.

[0087] like Figure 3 , Figure 4 As shown, in the middle of the cleaning mechanism 2 assembled by the water-guiding structure 41, the first fixing member 42, and the second fixing member 43, there is an air supply port 422 communicating with the air outlet. The main body of the air supply port 422 communicating with the air outlet is located in the middle of the first fixing member 42. The side of the first fixing member 42 facing the surface of the scrubbing roller 1 is an arc surface with a relatively large curvature (not shown in the figure). The arc surface, the air supply port 422, and the surface of the scrubbing roller 1 together form a second gap. The upper half of the air supply port 422 (not shown in the figure) is located in the middle of the water-guiding structure 41, and the lower half of the air supply port 422 (not shown in the figure) is located in the middle of the second fixing member 43. The two upper and lower half guide portions together form a complete guide portion of the air supply port 422 (not shown in the figure). The guide portion of the air inlet 422 can increase the air outlet area of ​​the air inlet 422, 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 roller 1, further reducing the noise generated by the washing vehicle device during the pressure relief and exhaust process.

[0088] like Figure 4 , Figure 5As shown, the housing 3 includes an upper end 31, a lower end 32, a housing body (not shown in the attached drawing), and a housing cover (not shown in the attached drawing). The housing body extends upwards and downwards to form the upper end 31 and the lower end 32. The housing cover fits onto the housing body to conceal the internal structure of the cleaning mechanism 2, improving the maintainability of the car wiping device while making its exterior appearance more complete and aesthetically pleasing. The upper end 31 and the lower end 32 of the housing elastically clamp the washing roller 1, and through the mounting holes and related water channels inside, they facilitate the rotation of the washing roller 1 while providing a continuous supply of water to clean the absorbent layer of the washing roller 1.

[0089] As a further improved implementation method, as needed, such as Figure 4 , Figure 5 As shown, the upper end 31 of the housing includes an upper end shell 311 and an upper end bottom shell 312. The upper end bottom shell 312 is integrally formed with the housing body. The upper end shell 311 is detachably fastened or slidably covered onto the upper end bottom shell 312. The upper end bottom shell 312 is provided with a washing roller engaging hole 3125 for engaging the end button (not shown in the figure) of the washing roller 1. The inner side of the upper end bottom shell 312 that engages the washing roller 1 is provided with a washing roller sliding step 3124 to facilitate the sliding out of the washing roller 1.

[0090] As a further improved implementation method, as needed, such as Figure 4 , Figure 5 As shown, the lower end portion 32 of the housing includes a lower end face shell 321 and a lower end bottom shell 322. The lower end bottom shell 322 is integrally formed with the housing body, and the lower end face shell 321 is detachably fastened or slidably fitted onto the lower end bottom shell 322. As a further improved embodiment, if necessary, the lower end bottom shell 322 may also be provided with a washing and wiping roller engaging hole (not shown in the figure) for engaging the end button (not shown in the figure) of the washing and wiping roller 1. The inner side of the lower end bottom shell 322 engaging the washing and wiping roller 1 is provided with a washing and wiping roller sliding step (not shown in the figure) to facilitate the sliding out of the washing and wiping roller 1.

[0091] As a further improved implementation method, as needed, such as Figure 6 As shown, the lower end shell 322 of the housing has a ring of radial reinforcing ribs (not shown in the figure) in the thickness direction, and racetrack-shaped transverse reinforcing ribs (not shown in the figure) are also provided perpendicular to the radial reinforcing ribs. This can further reduce the weight of the lower end shell 322 while ensuring the mechanical strength of the housing. Combined with... Figure 2 , Figure 5 , Figure 6Let's take a look. The lower end of the casing, bottom shell 322, facing the inner side of the snap-fit ​​washing roller 1, has a pipe connector (not shown in the attached diagram) for easy installation and connection of the return water inlet 51 to the return water pipe 5. On the side directly opposite the pipe connector, there is a wastewater side channel outlet 3222 connected to it. A wastewater collection port 3221 is provided in the area directly opposite the sealed liquid exchange zone A on the lower end of the casing, bottom shell 322. The area of ​​the wastewater collection port 3221 is larger than... Figure 2 The projected area of ​​the sealed liquid exchange zone A on the lower end shell 322 of the housing is designed to ensure that all "mixed water" flowing through the sealed liquid exchange zone can smoothly exit from the wastewater collection port 3221. The lower end shell 322 faces away from the outer side of the snap-fit ​​washing roller 1, and a wastewater channel 3223 connecting the wastewater side channel outlet 3222 and the wastewater collection port 3221 is provided. The lower end shell 322 also has two wire holes 3224 for the motor's power cable to pass through and out, and a wire passage 3225 connecting the two. After the lower end shell 321 is snapped or slid closed, a complete and leak-free wastewater side channel and wire passage are naturally formed on the inner side of the lower end shell 32. The internal channels are not visible to the user from the outer surface, ensuring both product maintainability and aesthetics. Figure 5 As shown, the thickness of the lower end 32 of the housing in the axial direction of the washing roller 1 is very thin. This is to further increase the proportion of the axial dimension of the washing roller 1 to the width dimension of the entire washing vehicle device, while ensuring that a complete and leak-free sewage side channel and wire passage are formed inside the lower end 32 of the housing. This achieves the effect of a small size of the washing vehicle device and a large width dimension of washing in a single wash.

[0092] As a further improved implementation method, as needed, such as Figure 7 As shown, the upper bottom shell 312 of the housing has a ring of radial reinforcing ribs (not shown in the figure) in the thickness direction, and racetrack-shaped transverse reinforcing ribs (not shown in the figure) are also provided perpendicular to the radial reinforcing ribs. This can further reduce the weight of the upper bottom shell 312 while ensuring the mechanical strength of the housing. Combined with... Figure 2 , Figure 5 , Figure 7 Let's take a look. The inner side of the upper bottom shell 312 facing the snap-fit ​​washing roller 1 has a pipe connector (not shown in the attached diagram) for easy installation and connection of the water outlet 41 to the water outlet pipe 4. A clean water inlet 3121 is provided on the side directly opposite the pipe connector. A clean water side channel outlet 3122 is provided in the area directly opposite the sealed liquid exchange zone A on the upper bottom shell 312. The area of ​​the clean water side channel outlet 3122 is smaller than... Figure 2The projected area of ​​the sealed liquid exchange zone A on the upper bottom shell 312 of the housing is designed to ensure that all clean water flowing through the outlet pipe 4 can smoothly reach the sealed liquid exchange zone. The upper bottom shell 312 faces away from the outer side of the snap-fit ​​washing roller 1, and a clean water channel 3123 connecting the clean water inlet 3121 and the clean water side channel outlet 3122 is provided. After the upper end shell 311 of the housing is snapped or slid closed, a complete and leak-free clean water side channel 3123 is naturally formed on the inner side of the upper end 31 of the housing. The user cannot see the internal channel from the outer surface, ensuring both product maintainability and aesthetics. Figure 4 , Figure 7 As shown, the upper bottom shell 312 of the housing is also provided with a washing roller engaging hole 3125 for engaging the end button (not shown in the attached figure) of the washing roller 1, and the inner side of the upper bottom shell 312 of the housing for engaging the washing roller 1 is provided with a washing roller sliding step 3124 to facilitate the sliding out of the washing roller 1. Figure 5 As shown, the thickness of the upper end 31 of the housing in the axial direction of the washing roller 1 is very thin. This is to further increase the proportion of the axial dimension of the washing roller 1 to the width dimension of the entire washing vehicle device, while ensuring that a complete and leak-free clean water channel is formed inside the upper end 31 of the housing. This achieves the effect of a small size of the washing vehicle device and a large width dimension of washing in a single wash.

[0093] It should be pointed out that, as Figure 6 As shown, since the opening of the sewage collection port 3221 is larger than the opening of the clear water side channel outlet 3122, from Figure 5 Looking from the middle F direction, such as Figure 6 As shown, the two are directly opposite each other, naturally they are... Figure 6 The outlines of both can be seen; because the opening of the sewage side channel outlet 3222 is larger than the opening of the clean water inlet 3121, from Figure 5 Looking from the middle F direction, such as Figure 6 As shown, the two are directly opposite each other and slightly offset, naturally they are... Figure 6 You can see the outlines or partial outlines of both. Similarly, as... Figure 7 The upper end 31 of the casing shown has a larger opening for the sewage collection port 3221 than for the clean water side channel outlet 3122, and the sewage side channel outlet 3222 is larger than the clean water inlet 3121. Figure 5 Looking at the E direction from the middle, such as Figure 7 As shown, the two are directly opposite each other, naturally they are... Figure 7 The outlines of the sewage side channel outlet 3222 and sewage collection port 3221 are not visible in the middle.

[0094] like Figure 5 As shown, combined with Figure 2 , Figure 5 , Figure 6 , Figure 7To 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 and wastewater outlet are located at opposite ends of the sealed fluid exchange zone.

[0095] It should be noted that the name "clean water side channel outlet 3122" is used when describing the internal flow channel of the upper end 31 of the housing. From another perspective, when discussing the flow channel within the sealed liquid exchange zone A, "clean water side channel outlet 3122" actually corresponds to the clean water inlet A1 of the sealed liquid exchange zone A. Although the names are different, those skilled in the art can understand that they actually refer to the same related component. Similarly, the name "sewage side channel outlet 3222" is used when describing the internal flow channel of the lower end 32 of the housing. From another perspective, when discussing the flow channel within the sealed liquid exchange zone A, "sewage side channel outlet 3222" actually corresponds to the sewage outlet A2 of the sealed liquid exchange zone A. Although the names are different, those skilled in the art can understand that they actually refer to the same related component.

[0096] As a further improved implementation method, as needed, such as Figure 8 , Figure 9 , Figure 10 As shown in Figure 11, the lower end of the housing 32 in another embodiment includes a lower end face shell 321 and a lower end bottom shell 322. The lower end bottom shell 322 is integrally formed with the housing body, and the lower end face shell 321 is detachably fastened to the lower end bottom shell 322.

[0097] As a further improved implementation method, as needed, such as Figure 8 , Figure 9 As shown, the difference between the lower end shell 322 of the housing and the previous embodiment is that the overall shape has been adjusted and multiple latches 3227 are provided at the part where it is fastened to the lower end shell 321 of the housing. Correspondingly, as Figure 10As shown, the inner edge of the lower end shell 321 of the housing that engages with the lower end bottom shell 322 of the housing is provided with multiple corresponding snap fasteners 3217. When engaged, the multiple snap fasteners 3227 engage with the corresponding snap fasteners 3217. The lower end shell 321 of the housing includes the lower end shell body 3211, a guardrail 3212 extending upward from the four edges of the lower end shell body, and a sewage channel weir 3213 extending upward from the contour line corresponding to the sewage channel 3223 projected on the lower end shell 322 on the lower end shell 321. To facilitate processing and forming, the guardrail 3212 and the sewage channel weir 3213 are fused together in the area where they are closest to each other, and the snap fasteners 3217 are located at the junction of the guardrail 3212 and the lower end shell body 3211. Figure 11 As shown, the area enclosed by the sewage channel weir 3213, including the inner wall of the weir 3213, is also coated with a layer of "soft rubber" using a secondary molding process. The outer edge of the guardrail 3212 and the back of the lower end shell body 3211 facing away from the sewage channel 3223 are also coated with a layer of "soft rubber" using the same secondary molding process. The top surface of the secondary molded "soft rubber" is higher than the top surface of the sewage channel weir 3213 and the top surface of the guardrail 3212. This allows the lower end shell 321 and the lower bottom shell 322 of the shell to interlock, achieving a complete seal for the sewage channel 3223 and effectively protecting the paint on the exterior surfaces of the lower end shell body 3211 and the guardrail 3212 from scratches during use. The "soft rubber" can be an elastic material, such as rubber or silicone, which is different from ordinary plastic molding materials, and is achieved through a coating process for secondary molding.

[0098] As a further improved implementation method, as needed, such as Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, in another embodiment, the upper end portion 31 of the housing includes an upper end shell 311 and an upper end bottom shell 312. The upper end bottom shell 312 is integrally formed with the housing body, and the upper end shell 311 is detachably fastened to the upper end bottom shell 312. As a further improved embodiment, if necessary, the upper end bottom shell 312 may also be provided with a washing roller engaging hole (not shown in the figure) for engaging the end button (not shown in the figure) of the washing roller 1, and the inner side of the upper end bottom shell 312 engaging the washing roller 1 is provided with a washing roller sliding step (not shown in the figure) to facilitate the sliding out of the washing roller 1.

[0099] As a further improved implementation method, as needed, such as Figure 12 , Figure 13 As shown, the difference between the upper bottom shell 312 of the housing and the previous embodiment is that the overall shape has been adjusted and multiple latches 3127 are provided at the part where it is fastened to the upper surface shell 311 of the housing. Correspondingly, as shown... Figure 14 As shown, the inner edge of the upper end shell 311 and the upper end bottom shell 312 of the housing is provided with multiple corresponding snap fasteners 3117. When fastened, the multiple snap fasteners 3127 engage with the corresponding snap fasteners 3117. The upper end shell 311 includes the upper end shell body 3111, the guardrail 3112 extending upward from the four edges of the upper end shell body, and the clear water side channel embankment 3113 extending upward from the outline of the clear water side channel 3123 projected on the upper end shell 312 onto the upper end shell 311. To facilitate processing and forming, the guardrail 3112 and the clear water side channel embankment 3113 are fused together in the area where they are closest to each other, and the snap fasteners 3117 are located at the junction of the guardrail 3112 and the upper end shell body 3111. Figure 15 As shown, the area enclosed by the cofferdam 3113 on the clear water side channel, including the inner wall of the cofferdam 3113, is also coated with a layer of "soft rubber" using a secondary molding process. The outer edge of the guardrail 3112 and the back of the upper shell body 3111 of the housing, as well as the back of the clear water side channel 3123, are also coated with a layer of "soft rubber" using the secondary molding process. The top surface of the secondary-molded "soft rubber" is higher than the top surface of the cofferdam 3113 and the top surface of the guardrail 3112. Thus, after the upper shell body 311 and the upper bottom shell 312 of the housing are interlocked, the "soft rubber" can completely seal the clear water side channel 3123 and effectively protect the paint surface of the upper shell body 3111 and the guardrail 3112 from scratches during use. The "soft rubber" can be an elastic material, such as rubber or silicone, which is different from ordinary plastic molding materials, and is achieved through a coating process to achieve secondary molding.
