[0061] 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.

[0062] like Figures 1-8 As shown, the present invention provides an embodiment of a cleaning mechanism for a washing and wiping vehicle.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] This embodiment uses the cleaning mechanism 2 as an example of a separate component structure for illustration.

[0069] like Figure 2 , Figure 4 ,Figure 5 As shown, the interference structure assembly 20 includes a first interference part 200 which is extruded with the surface of the scrubbing roller 1, the first interference part 200 is provided with a fixed part 201 and a sealing part 202 respectively along the circumferential direction of the surface of the scrubbing roller 1, the sealing part 202 extends outwardly to form an installation part 207 with a flat installation surface for fixing the water guide structure 21, the sealing part 202 cooperates with the water guide structure 21 to form a sealed liquid exchange area A on the surface of the scrubbing roller 1, and the fixed part 201 can be fixed with the shell 3.

The arc direction of the arc-shaped protruding part 2001 deviates from the axial direction of the scrubbing roller 1, and the arc can be gradually changed along or against the rotation direction of the scrubbing roller 1.

[0071] As shown in Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, the water guide structure 21 includes a water guide part 211 in contact with the surface of the scrubbing roller 1, a water storage part 214 connected with the water guide part, a guide strip 212 interfering with the surface of the two ends of the scrubbing roller 1, and an extension part 210 having a first gap B1 between the surface of the scrubbing roller 1, the circumferential end of the water guide part 211 is provided with a second interference part 2111 in water-tight contact with the surface of the scrubbing roller 1, and the water guide part 211 is provided with the guide strip 212 interfering with the surface of the two ends of the scrubbing roller 1 at both ends in the length direction, that is, the guide strip 212 is in partial contact with the surface of the scrubbing roller 1.

The water storage part 214, the guide strip 212 of the water guide part 211, and the sealing part 202 cooperate with the surface of the scrubbing roller 1 to form a complete sealed liquid exchange area A. The extension part 210 and the water guide part 211 are located on both sides of the water storage part 214, respectively. The water storage part 214 and the sealing part 202 are fixed by waterproof connection.

[0072] As a further improved embodiment, the second interference part 2111 can adopt a strip structure, which has a contact surface with the surface of the scrubbing roller 1 as small as possible, which can ensure that water does not leak from the second interference part 2111 during water exchange, while reducing the rotation resistance of the scrubbing roller 1 during work, and effectively expanding the gap length in the circumferential direction of the scrubbing roller 1, thereby increasing the pressure relief area.

The inner side of the guide strip 212 is provided with a slope 2121, which is an arc structure. The arc structure of the slope 2121 can keep the contact pressure of each part of the slope in contact with the surface of the scrubbing roller 1 substantially the same. The guide strip 212 extends in the direction of the sealed liquid exchange area A and has a protrusion 2122, which is surrounded by the first interference part 200, the second interference part 2111, the water storage part 214 and the sealing part 202 on both sides of the sealed liquid exchange area A to form a part of the sealed liquid exchange area A of the scrubbing roller 1 close to the two ends of the scrubbing roller 1.

The extension part 210 and the water guide part 211 are located on both sides of the water storage part 214, respectively. The water storage part 214 and the sealing part 202 are fixed by waterproof connection.

[0074] As shown in Figure 2 、 Figure 3As shown, the cleaning mechanism 2 further comprises a first fixing member 22 and a second fixing member 23 for fixing the water guide structure 21 in cooperation with the sealing part 202, the first fixing member 22 needs to be fixed through the second fixing member 23, the first fixing member 22 is arranged as an arc-shaped structure near the side surface of the scrubbing roller 1, and the arc-shaped structure is provided with a second gap B2 communicating with the first gap B1 between the arc-shaped structure and the surface of the scrubbing roller 1, the first gap B1 and the second gap B2 form a pressure relief chamber B, because the first gap B1 and the second gap B2 form a larger area projection on the surface of the scrubbing roller 1, when pressure relief is needed, the pressure relief gas outlet 27 is communicated with the pressure relief chamber B through an electromagnetic valve (not shown in the figure), which can be quickly absorbed by the scrubbing roller 1, thereby avoiding the phenomenon of bubbles and the like when the pressure is released to the scrubbing roller 1.

[0075] As a further improved embodiment, as shown in 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.

[0076] As a further improved embodiment, as shown in Figure 2 、 Figure 4 As shown, the pressure relief gas outlet 27 is directly communicated with 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.

[0077] As a further improved embodiment, according to needs, as shown in Figure 4 、 Figure 5 As shown, the cleaning mechanism 2 further comprises a third interference part 231 of the second fixing member 23 formed on the surface of the scrubbing roller 1, and the third interference part 231 can adopt a strip-shaped structure. The third interference part 231 can be arranged on the first fixing member 22 or other components.

When the third interference part 231 is located on the second fixed part 23, it can be conveniently removed for cleaning.

[0079] As a further improved embodiment, the third interference part 231 can be provided on other parts as needed, and can be conveniently removed for cleaning.

[0080] As shown in Figure 2 , Figure 5 As shown, the sealing part 202 forms a groove (not shown in the drawing) between the side opposite the first interference part 200 and the fixed part 201, and the cross section of the groove in the length direction is a V-shaped groove.

The surface area of the scrubbing roller 1 forming part of the pressure relief chamber B is greater than the surface area of the scrubbing roller 1 forming part of the sealing liquid exchange area A, and since the surface area of the scrubbing roller 1 is smaller, the air is limited, and the pressure relief chamber B has a larger area, so the pressure relief can be more easily performed.

[0083] As shown in 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] like Figure 6 , Figure 7As shown, in the middle of the cleaning mechanism 2 assembled by the guide structure 21, the first fixing member 22 and the second fixing member 23, a pressure relief port 222 is provided in communication with the air outlet 27, the main part of the pressure relief port 222 in communication with the air outlet 27 is provided in the middle of the first fixing member 22, the side of the first fixing member 22 facing the surface of the scrubbing roller 1 is an arc surface 223 with a corresponding curvature, the arc surface 223, the pressure relief port 222 and the surface of the scrubbing roller 1 together enclose a second gap B2. The upper half of the guiding part of the pressure relief port 222 (not shown in the figure) is provided in the middle of the guide structure 21, and the lower half of the guiding part of the pressure relief port 222 (not shown in the figure) is provided in the middle of the second fixing member 23, and the two halves of the guiding part of the pressure relief port 222 together enclose a complete guiding part of the pressure relief port 222 (not shown in the figure). The guiding part of the pressure relief port 222 can increase the air outlet area of the pressure relief port 222, further reduce the air flow rate, and at the same time, it is more beneficial for the discharged air to be evenly dispersed to the surface of the scrubbing roller 1, further reducing the noise generated by the scrubbing vehicle device during the pressure relief and air exhaust process.

[0088] As a further improved embodiment, according to the needs, Figure 8 As shown, an exhaust pipe interface seat 35 is provided in the middle of the side of the first fixing member 22 away from the scrubbing roller 1, which is used to connect the pressure relief pipeline (not shown in the figure), and the exhaust pipe interface seat is internally provided with an air outlet 27. When the pressure accumulated inside the scrubbing vehicle device needs to be released, the pressure relief pipeline discharges air to the pressure relief chamber B through the air outlet 27 in the exhaust pipe interface seat 35, and the pressure relief chamber B further releases the accumulated pressure, thereby achieving the release of the pressure accumulated inside the scrubbing vehicle device.

[0089] As shown, Figure 8 As shown, Figure 2 In order to maintain the continuous exchange of the sealed liquid exchange area A during work, the sealed liquid exchange area A can be respectively provided with a clean water input port A1 in communication with the water outlet 41 and a sewage output port A2 in communication with the water inlet 51, wherein the clean water input port can be in communication with a cleaning liquid container (not shown in the figure) through a water pump (not shown in the figure), and the sewage output port can also be in communication with a sewage container (not shown in the figure) through a water pump, and a conversion device (not shown in the figure) can be provided between the sewage container and the cleaning liquid container, such as converting sewage into cleaning liquid, so that the vehicle can be continuously scrubbed for a longer period of time. The cleaning liquid can include clean water or a mixture of clean water and cleaning liquid, or only cleaning liquid. The cleaning liquid input port A1 and the sewage output port A2 are respectively located at the two ends of the sealed liquid exchange area A.

[0090] As a further improved embodiment, the first interference part 200 can be triangular in cross-section, with the top of the triangle being a smooth arc, so as to reduce the contact area and friction when the interference part 200 is in contact with the surface of the wiping roller 1, thereby prolonging the service life of the wiping roller 1.

[0091] As a further improved embodiment, the second fixing part 23 can be A-shaped, as shown in Figure 7 、 Figure 9 The second fixing part 23 can be A-shaped, as shown in FIG. 6. The third interference part 231 of the second fixing part 23 is continued in the length direction and radially upward along the outer surface of the wiping roller 1 to form an A-shaped water-collecting protrusion 234. The second fixing part 23 is continued in the length direction at the water-collecting protrusion 234, and the interference between the second fixing part 23 and the outer surface of the wiping roller 1 gradually decreases to zero, so that a gap is formed between the second fixing part 23 and the outer surface of the wiping roller 1, thereby forming a collapse section 232. The second fixing part 23 is slightly interfered with the outer surface of the wiping roller 1 at the third interference part 231 and the water-collecting protrusions 234, and a fine-particle garbage collecting space G for collecting fine-particle garbage is formed at the lower part of the second gap B2. On the one hand, the third interference part outside 2311 of the third interference part 231 is located closest to the surface of the vehicle. When there is fine-particle garbage, the fine-particle garbage can be separated from the surface of the wiping roller 1 by the third interference part outside 2311. When the fine-particle garbage is adhered to the highest point of the third interference part 231 under the adhesion of the water-absorbing layer 11 of the surface of the wiping roller 1, the fine-particle garbage is deposited at the concave side 2312 of the third interference part 231 under the impact of the discharge air discharged through the air outlet 27 and the re-wetting of the water-absorbing layer 11 by the sewage squeezed out through the first interference part 200. When the third interference part 231 is located on the second fixing part 23, the second fixing part 23 can be easily removed, thereby facilitating the cleaning of the fine-particle garbage deposited in the fine-particle garbage collecting space G. On the other hand, when the discharge air discharged through the air outlet 27 to the pressure relief chamber B encounters the fine-particle garbage collecting space G filled with fine-particle garbage or sewage, the discharge air is discharged to the outside of the vehicle washing device through the first air discharge gap D1 and the second air discharge gap D2 formed by the gap between the collapse section 232 of the second fixing part 23 and the surface of the wiping roller 1, thereby achieving the discharge of the pressure accumulated in the vehicle washing device.

[0092] As a further improved embodiment, the housing 3 is provided with a mounting position for mounting the wiping roller 1, and one side of the mounting position is provided with a non-circular fixing hole 31 for fixing the rotating shaft at one end of the wiping roller 1. In order to facilitate the installation, the housing 3 is further provided with a mounting guide slot 32 connected with the fixing hole 31, and the width of the mounting guide slot 32 decreases from the outer edge to the fixing hole 31.
