[0066] 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.

[0067] like Figures 1-10 As shown, the present invention provides an embodiment of a solid collection mechanism for a car washing device.

[0068] like Figure 1 , Figure 2As shown, the solid collection mechanism of the washing and wiping vehicle device includes a washing head and a handle (not shown in the figure) connected to the washing head. The washing head includes a housing 3, a washing roller 1, and a cleaning mechanism 2 mounted on the housing 3. The washing roller 1 continuously washes the vehicle surface by rolling continuously. The cleaning mechanism 2 continuously cleans the surface of the washing roller after washing the vehicle surface and maintains the surface humidity of the washing roller. The cleaning mechanism 2 includes a sealed liquid exchange zone A. 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 the like through a transmission mechanism, achieving continuous washing by rolling the washing roller on the vehicle surface. The cleaning mechanism 2 continuously cleans the surface of the washing roller 1 after washing the vehicle surface and maintains the surface humidity of the washing roller. It includes a cleaning component, which includes an interference structure 20 that forms a sealed liquid exchange zone A on the surface of the washing roller 1 and squeezes the liquid on the washing roller 1 into the sealed liquid exchange zone A.

[0069] 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.

[0070] 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.

[0071] This embodiment uses the cleaning mechanism 2 as an example of a separate component structure for illustration.

[0072] like Figure 2 , Figure 4 , Figure 5 As shown, the interference structure 20 includes a first interference portion 200 that forms a pressure with the surface of the washing roller 1. The first interference structure 200 has a fixing portion 201 and a sealing portion 202 on both sides of the circumferential direction of the washing 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 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 water-sealed contact on the surface of the washing roller 1.

[0073] like Figure 3 , Figure 4 , Figure 5As shown, the water-guiding structure 21 includes a water-guiding part 211 in contact with the surface of the scrubbing roller 1, a water-storing part 214 connected to the water-guiding part 211, guide strips 212 that cause interference between the two ends of the scrubbing roller 1, and an extension part 210 with a first gap B1 between it and the surface of the scrubbing 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 scrubbing roller 1. Guide strips 212 that cause interference between the two ends of the scrubbing 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 scrubbing 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 scrubbing 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 surface of the washing roller 1 to form a 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 the 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 together using a waterproof connection.

[0074] like Figure 2 , Figure 3 , Figure 4 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 and rubbing 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 and rubbing 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 large area projection on the surface of the washing and rubbing roller 1, when pressure relief is required, 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 and rubbing roller 1 more quickly, thereby avoiding the phenomenon of bubbles when the pressure is released to the washing and rubbing roller 1.

[0075] As needed, the pressure relief chamber B is a semi-sealed structure. This chamber also includes a third interference portion 231, located near the vehicle surface of the washing roller 1, parallel to the axis of the washing roller 1 and forming a semi-closed shape circumferentially around the washing roller. This third interference portion can be a separate detachable part or a part of a component. The pressure relief chamber B is called a "semi-sealed structure" primarily because the third interference portion only forms a semi-closed shape circumferentially around the washing roller in its own length direction. Gaps remain between the third interference portion and the washing roller 1 at both ends in the length direction (not shown in the attached diagram). Details will be provided in the following paragraphs describing the pressure relief channel and in the appendix of the instruction manual. Figure 7 , Figure 10 The description provides a detailed description of the pressure relief chamber B, which has pressure relief channels at both ends near the washing roller 1. Therefore, the pressure relief chamber B is a semi-sealed structure.

[0076] As a further improved implementation method, as needed, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the cleaning mechanism also includes a third interference portion 231 formed on the surface of the scrubbing roller 1 by the second fixing member 23. This third interference portion 231 can be a strip-shaped structure, such as an interference strip. 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 is located near the vehicle surface and parallel to the axis of the scrubbing roller 1. 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 scrubbing roller 1 when the pressure is high.

[0077] like Figure 5 As 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 scrubbing 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 scrubbing 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 scrubbing roller 1 by the action of the outer side 2311, and aggregated on the inner side 2312. When the third interference portion 231 is located on the second fixing member 23, it can be easily removed for cleaning.

[0078] 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.

[0079] As a further improved implementation method, as needed, such asFigure 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 upwards along the outer surface of the scrubbing rod 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 scrubbing rod 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 scrubbing rod 1 at the third interference portion 231 and the two water-collecting protrusions 234, forming a collection space G at the lower part of the second gap B2. Further, the collection space includes a fine particulate waste collection space. 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 scrubbing 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 cleaning device, thereby releasing the pressure accumulated inside the car cleaning device.

[0080] The solid collection mechanism for the vehicle washing device includes an interference strip 231 that is parallel to the axial direction of the washing roller 1 and is located near the vehicle surface. A fine particulate waste collection space G is formed between the interference strip on the side of the interference strip at a distance from the vehicle surface and the surface of the washing roller.

[0081] When the washing and wiping roller removes fine solid particles from the vehicle surface during use, the interference strip first applies pressure to the surface of the washing and wiping roller, causing a sudden change in the surface. Under the elasticity of the washing and wiping roller itself, the rear side of the interference strip quickly recovers, causing the fine solid particles attached to the surface of the washing and wiping roller to leave the surface. Moreover, there is a fine particle collection space G on the side of the interference strip away from the surface of the washing and wiping roller, which can gather and concentrate the fine solid particles, preventing them from adhering to the surface of the washing and wiping roller and causing scratches when passing over the vehicle surface again.

[0082] Meanwhile, since the third interference section 231 is located 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 third interference section 231, and will accumulate on the outer side 2311 of the third interference section. It will not enter the fine particulate waste collection space G. Only when the particulate waste is adhered to by the adhesive effect of the water-absorbing layer 11 on the surface of the wetted scrubbing roller 1 and passes the highest point of the third interference section 231, can a small amount of fine particulate waste be deposited in the collection space G. The fine particulate waste blocked outside the collection space G and the fine particulate waste deposited on the collection space G will not scrape the vehicle surface again as the scrubbing roller 1 rotates, which is beneficial to protecting the paint of the vehicle to be cleaned. When the third interference section 231 is located on the second fixing member 23, it can be easily removed, thus facilitating cleaning.

[0083] As a further improved implementation method, as needed, such as 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.

[0084] 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 and wastewater outlet are located at opposite ends of the sealed fluid exchange zone.

[0085] Only a very small number of fine particles, after passing through the two checkpoints of the outer side 2311 of the third interference section and the fine particle collection space G, are stuck into the sealed liquid exchange zone A by the adhesive effect of the water-absorbing layer 11 on the surface of the wet scrubbing roller 1. These few fine particles will be carried away by the water flow and will not scrape the vehicle body surface again with the rotation of the scrubbing roller 1, which is beneficial to protecting the paint of the vehicle to be cleaned.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
