Description

[0001] This application is a divisional application of Chinese Patent Application No. 2022112552996, filed on October 13, 2022, entitled "An Online Water Squeezing Mechanism Based on a Car Washing Device", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of vehicle cleaning technology, and in particular to a water-squeezing structure component and an online water-squeezing mechanism based on a car wiping device. Background Technology

[0003] 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.

[0004] Chinese patent CN201420322721.X discloses a split-type combined car wash machine, which solves the aforementioned problems of the prior art. It is an environmentally friendly, ultra-compact car wash machine that requires no water source, electric pump, water pipes, water tank, or spray gun, and is water-saving and energy-efficient. It includes a power control handle and separate sweeping and washing mechanisms. In use, the sweeping mechanism first cleans the surface of the car body of dust and sand, and then the washing mechanism cleans the surface of the car body to achieve a cleaning effect.

The online water-squeezing mechanism also includes a water-guiding structure that contacts the surface of the car wiping roller. This water-guiding structure cooperates with the sealing portion to form a sealed liquid exchange zone axially on the roller surface. In use, the online water-squeezing mechanism can continuously squeeze the car wiping roller, carrying away debris such as dust through the discharged water. The squeezed-out liquid is wastewater. Since it is impossible to effectively squeeze out all the wastewater from the car wiping roller during the squeezing process, clean water is injected into the sealed liquid exchange zone to dilute the wastewater, making the liquid that can be absorbed by the roller surface in contact with the liquid exchange zone slightly cleaner. This keeps the surface of the car wiping roller clean and avoids the phenomenon of wiping without leaving stains after continuous wiping. Attached Figure Description

[0078] 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.

[0079] like Figures 1-5 As shown, the present invention provides an embodiment of an online water-squeezing mechanism based on a car wiping device.

[0080] like Figure 1 As shown, the online dewatering mechanism based on the car wiping device includes a dewatering structure assembly 2 that interferes axially with the surface of the car wiping roller 1. This assembly includes a first interference portion 20, a fixing portion 21 connected to both sides of the first interference portion, and a sealing portion 22. The sealing portion 22, the first interference portion 20, and the fixing portion 21 are distributed circumferentially along the car wiping roller 1. The online dewatering mechanism also includes a water-guiding structure 61 that contacts the surface of the car wiping roller 1 to form a water seal. The sealing portion 22 extends outward to form a mounting portion 27 with a straight mounting surface for fixing the water-guiding structure 21. The water-guiding structure 61 and the sealing portion 22 cooperate to form a sealed liquid exchange zone A axially on the surface of the roller 1. The fixing portion 21 can be fixed to the housing of the car wiping device. The water-guiding structure 61 can connect with the sealing portion 22 to form a water-sealed contact on the surface of the washing roller 1.

[0081] The online dewatering mechanism can be an integral structure. Although the online dewatering mechanism is implemented by multiple parts in the following embodiments, the component numbers and names involved in the following description are consistent with those of 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.

[0082] As a further improved implementation, the online dewatering mechanism 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.

[0083] This embodiment uses an online dewatering mechanism as an example of a separating component structure for illustration.

[0084] like Figure 1 , Figure 4 As shown, specifically, the online squeezing mechanism refers to the entire assembly of all related components that can continuously squeeze the car wiping roller 1 and continuously discharge sewage during the rotation of the car wiping roller 1.

[0085] like Figure 1As shown, the first interference portion 20 interferes with the surface of the car-wiping roller 1, thus exerting a squeezing effect on the surface of the car-wiping roller 1 even when the surface of the car-wiping roller 1 is under certain deformation. The car-wiping roller 1 is typically a sponge roller, i.e., the surface has a layer of liquid-absorbing sponge and a bracket for fixing and supporting the sponge (not shown in the figure). A V-shaped groove 23 is formed between the sealing portion 22 and the fixing portion 21 on the side opposite to the first interference portion 20. The V-shaped groove 23 can reduce the weight of the water-squeezing structure assembly 2, making it more convenient to wash the vehicle. The cross-sectional shape of the first interference portion 20 is not limited. In this embodiment, it is set to have a triangular cross-section, which can reduce the contact area with the car-wiping roller 1 during squeezing, thereby reducing the rotational resistance of the car-wiping roller 1. The first interference portion 20 is used to squeeze the roller surface.

[0086] In practical engineering, since the water-squeezing structure component 2 is usually made of plastic, in order to maintain its strength requirements, a rib 25 is provided between the sealing part and the fixing part on the side opposite to the first interference part 20. A rib 25 is also provided on the back of the first interference part, connecting the sealing part 22 and the fixing part 21. In this embodiment, multiple ribs are provided, and each fixing plate 25 is arranged in parallel. The first interference part 20 has a V-shaped cross-section, which allows for the squeezing of the car wiping roller 1 while reducing the contact area with the roller 1, effectively reducing resistance during water squeezing.

[0087] like Figure 1 As shown, the sealing part 22 is located on the side of the car wiping roller 1 that squeezes out sewage, and the fixing part 21 is located on the side of the car wiping roller 1 that has squeezed out all the sewage.

[0088] like Figure 1 , Figure 4 , Figure 5 As shown, the water-squeezing structure assembly 2 also includes a water-guiding strip 61 that contacts the surface of the car-wiping roller 1. The water-guiding strip 61 includes a contact portion 611 that contacts the surface of the car-wiping roller 1 and a water-storing portion 614 connected to the contact portion 611. The water-storing portion 614 cooperates with the sealing portion 22 to form a sealed liquid exchange zone A axially on the roller surface 1. Since the direction is not constant during car wiping, to ensure that no liquid seeps out or leaks, the liquid exchange zone A must be set as a sealed structure.

[0089] To better understand the function of the sealed liquid exchange zone A, its working process will be explained in detail. For example... Figure 1 , Figure 4As shown, when the car wiping roller 1 wipes the vehicle surface, it inevitably carries dust. When the wet car wiping roller 1 passes through the first interference section 20, the liquid inside the car wiping roller 1 is discharged or flows out. During the discharge or flow out process, dust and other debris are carried away from the surface of the car wiping roller 1. On the one hand, the first interference section 20 cannot completely squeeze out all the liquid on the car wiping roller 1 (not due to technical limitations, but because the car wiping roller 1 is usually a sponge roller, and to a certain extent it is unnecessary to completely squeeze the entire sponge roller dry in the non-squeezing area). On the other hand, excessive squeezing force would cause the car wiping roller 1 to have excessive resistance and become unable to work. In order to maintain a certain level of moisture and cleanliness of the adsorbed liquid in the car wiping roller 1, liquid is injected into the liquid exchange zone A to dilute the wastewater, ensuring that the cleanliness of the car wiping roller 1 before contact with the vehicle is greater than after contact. This can avoid the presence of stains after wiping during continuous wiping.

[0090] In this embodiment, the water-guiding structure 61 in the online water-squeezing mechanism is a separate component from other parts, but it can also be set as an integral structure as needed.

[0091] As needed, such as Figure 1 , Figure 4 As shown, the water storage section 614 and the sealing section 22 are arc-shaped. The contact section 611 extends into the sealed liquid exchange zone A, so that the wastewater discharged during the squeezing of the car cleaning roller 1 will not stagnate at the contact position with the surface of the car cleaning roller 1, and fine particles can be effectively settled. The water inlet section near the sealed liquid exchange zone A is in contact with the surface of the car cleaning roller 1, and a gap B1 is provided between the water inlet section away from the sealed liquid exchange zone A and the surface of the car cleaning roller 1. The sealed liquid exchange zone has an arc-shaped cross-section along its length perpendicular to the cross-section, and the arc shape includes a C-shape.

[0092] As a further improved implementation method, as needed, such as Figure 4 As shown, the first interference part 20 has protrusions 201 at both ends. The extrusion force formed by the protrusions 201 on the surface of the car wiping roller 1 is less than or equal to that of the first interference part 20. The protrusions 201 can prevent the liquid on both sides of the car wiping roller 1 from seeping outward when squeezing water.

[0093] As a further improved implementation method, as needed, such as Figure 4As shown in the figure, the protrusion 201 is not on the same straight line as the first interference portion 20 in the length direction. It is preferably extended into the sealed liquid exchange zone A, so that the squeezed liquid can be gathered in the middle and prevent leakage from both sides. The protrusion 201 is arc-shaped in the axial direction of the wiping roller 1. The arc-shaped protrusion 201 deviates from the axial arc direction of the wiping roller 1. The arc can be gradually changed in the direction of rotation of the wiping roller 1, either with or without the direction of rotation.

[0094] like Figure 4 , Figure 5 As shown, the water-guiding structure 61 includes a water-guiding part 611 in contact with the surface of the car-wiping roller 1, a water-storing part 614 connected to the water-guiding part, guide strips 612 that cause interference between the two ends of the car-wiping roller 1, and an extension part 610 with a first gap B1 between it and the surface of the car-wiping roller 1. The circumferential end of the water-guiding part 611 is provided with a second interference part 6111 that forms a water seal with the surface of the car-wiping roller 1. Guide strips 612 that cause interference between the two ends of the car-wiping roller 1 are provided at both ends of the length direction of the water-guiding part 611, that is, the guide strips 612 are in partial contact with the surface of the car-wiping roller 1. The inner side of the guide strip 612 is provided with an inclined surface 6121. The inclined surface 6121 has an arc-shaped structure. The arc-shaped structure design of the inclined surface 6121 can keep the contact pressure of each part when the inclined surface contacts the surface of the car-wiping roller 1 basically the same. The guide strip 612 extends towards the sealed liquid exchange zone A with protrusions 6122. These protrusions 6122, together with the first interference portion 20, the second interference portion 6111, the water storage portion 614, and the sealing portion 22, enclose the sealed liquid exchange zone A near the two ends of the car cleaning roller 1 on both sides of the sealed liquid exchange zone A. The water storage portion 614, the water intake portion 611, the guide strip 612, and the sealing portion 22 cooperate with the surface of the car cleaning roller 1 to form a complete sealed liquid exchange zone A. The extension portion 610 and the water intake portion 611 are located on both sides of the water storage portion 614. The water storage portion 614 and the sealing portion 22 are fixed by a waterproof connection.

[0095] As a further improved implementation, the second interference part 6111 can adopt a strip structure, and the contact surface formed between it and the surface of the car cleaning roller 1 is as small as possible. This can ensure that no leakage occurs from the second interference part 6111 during the water exchange process, while also reducing the rotational resistance of the car cleaning roller 1 during operation. In addition, it can effectively increase the gap length in the circumferential direction of the car cleaning roller 1, thereby increasing the pressure relief area.

[0096] As a further improved implementation method, such as Figure 5 , Figure 6 , Figure 7As shown, the water-guiding structure 61 includes a water-guiding part 611 that contacts the surface of the car-wiping roller 1, a water-storing part 614 connected to the water-guiding part 611, and an extension part 610 with a first gap B1 between it and the surface of the car-wiping roller 1. The circumferential end of the water-guiding part 611 is provided with a second interference part 6111 that forms a watertight contact with the surface of the car-wiping roller 1. The water-guiding part 611 extends all the way to the end of the car-wiping device housing that clamps the car-wiping roller 1 from the top and bottom. This eliminates the need for the complex structure of guide strips 612 that extend at both ends of the water-guiding part 611 in the length direction to cause interference between the surfaces of the two ends of the car-wiping roller 1. This implementation can reduce the processing and manufacturing difficulty of the water-guiding structure 61.

[0097] like Figure 4 , Figure 5 As shown, the straight portion 616 of the water-guiding structure 61 has several through holes (not shown in the figure), and the top of the first fixing member 62 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 27 of the water-squeezing structure assembly 2 through the top of the straight portion 616 of the water-guiding structure 61, the fastening screws can be driven into the nut posts on the top of the first fixing member 62, thereby realizing the installation of the large component of the water-squeezing structure assembly 2. Furthermore, the second fixing member 63 can be detachably connected to the first fixing member 62 by an interference fit through an opening at the bottom of the first fixing member 62 (not shown in the figure). To facilitate disassembly and assembly, a gap 621 is left between the second fixing member 63 and the first fixing member 62 so that the compressed air during the interference fit insertion process still has some space, improving the convenience of disassembly and assembly.

[0098] like Figure 4 , Figure 5 As shown, in the middle of the online water-squeezing mechanism assembled by the water-guiding structure 61, the first fixing member 62, and the second fixing member 63, a pressure relief port 622 communicating with the air outlet 28 is provided. The main body of the pressure relief port 622 communicating with the air outlet 28 is located in the middle of the first fixing member 62. The side of the first fixing member 62 facing the surface of the car wiping roller 1 is an arc surface 623 with a similar curvature. The arc surface 623, the pressure relief port 622, and the surface of the car wiping roller 1 together form a second gap B2. The upper half of the pressure relief port 622 (not shown in the figure) is located in the middle of the water-guiding structure 61, and the lower half of the pressure relief port 622 (not shown in the figure) is located in the middle of the second fixing member 63. The two upper and lower half guide portions together form a complete guide portion of the pressure relief port 622 (not shown in the figure). The guide portion of the pressure relief port 622 can increase the air outlet area of ​​the pressure relief port 622, 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 car washing roller 1, further reducing the noise generated by the car washing device during the pressure relief and exhaust process.

[0099] As a further improved implementation method, as needed, such as Figure 3 As shown, an exhaust pipe interface seat 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 62 facing away from the car wiping roller 1. The exhaust pipe interface seat has an air outlet 28 inside. When it is necessary to release the pressure accumulated inside the car wiping device, the pressure relief pipeline discharges air to the pressure relief chamber B through the air outlet 28 in the exhaust pipe interface seat. The pressure relief chamber B further releases the accumulated pressure, thereby realizing the release of the pressure accumulated inside the car wiping device.

[0100] like Figure 3 As shown, the cleaning fluid holding mechanism (not shown in the attached figure) of the car wiping device can deliver clean water and collect wastewater through an interface mechanism (not shown in the attached figure). Clean water is delivered to the clean water pipe 6 through the clean water outlet (not shown in the attached figure), and wastewater is collected in the wastewater pipe 7 through the wastewater return outlet (not shown in the attached figure). Figure 1 To ensure continuous exchange of the sealed liquid exchange zone A during operation, it can be equipped with a clean water inlet A1 connected to the outlet pipe 61 and a wastewater outlet A2 connected to the return water inlet 71. 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 for 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 wastewater outlet A2 are located at opposite ends of the sealed liquid exchange zone A. This design, with the clean water inlet and wastewater outlet located at opposite ends of the sealed liquid exchange zone, improves the efficiency of the alternating replacement of wastewater in the squeezed-out cleaning rollers and clean water in the injected cleaning rollers.

[0101] As a further improved implementation, as needed, in the above embodiments, the cross-section of the first interference part 20 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 wiping roller 1, thus extending its service life.

[0102] During use, the online squeezing mechanism continuously squeezes the car wiping roller, carrying away debris such as dust through the discharged water. The squeezed-out liquid is wastewater. Since it is impossible to effectively squeeze out all the wastewater from the car wiping roller during the squeezing process, clean water is injected into the sealed liquid exchange area to dilute the wastewater, making the liquid that can be absorbed by the roller surface in contact with the liquid exchange area slightly cleaner. This keeps the surface of the car wiping roller clean and avoids the phenomenon of wiping without leaving any stains after continuous wiping.

[0103] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. 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.
