Description

Technical Field

[0001] This utility model relates to the field of window cleaning robots, and in particular to an atomizing device and a window cleaning robot. Background Technology

[0002] Window cleaning robots, as intelligent equipment for modern cleaning operations, are widely welcomed in the market due to their intelligence and unmanned operation. Their basic principle is to firmly fix the machine to the glass surface through vacuum adsorption, and then use a drive mechanism to move the cleaning module across the glass to complete the wiping process. To improve cleaning effectiveness, modern window cleaning robots are generally equipped with a water spray system, designed to spray cleaning fluid or water onto the glass surface before or during wiping to dissolve dust and stains and avoid scratches caused by dry wiping.

[0003] Existing window cleaning robots typically have two atomizing components tilted towards each other. The purpose of this is to allow the two sprays to cross and mix in the central area in front of the machine. This cross spraying can enhance the liquid concentration in the central area, or achieve more thorough mixing and more uniform diffusion through the interaction of the two mist streams.

[0004] However, through in-depth research and practice, the inventors of this application discovered that this design approach, which pursues cross-spraying, has corresponding drawbacks. The cross-impact of the two liquids actually causes a large number of droplets to accumulate in the central area, while the edges of the machine remain dry due to insufficient liquid. This not only fails to achieve the expected uniform distribution but also creates a problem of excessive wetness in the middle and excessive dryness on both sides. Consequently, when the cleaning cloth passes through the water spray area, only a small area in the center corresponding to the water flow convergence point is fully wetted, while the sides and edges of the cloth remain relatively dry or semi-wet. This significant difference in moisture prevents the cloth from removing stains with overall, uniform adsorption. The unevenly moistened cleaning cloth also poses a risk of slipping, affecting cleaning effectiveness and increasing the likelihood of the robot falling. Furthermore, cross-spraying also limits the effective coverage width. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an atomizing device and a window cleaning robot, which aims to solve at least one of the problems of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In the above technical solution, the preset spacing is the distance between the central axes of the nozzles of the two atomizing components, and the value range of the preset spacing is 2 / 3 to 2 times the length of the atomizing component itself, or the value range of the preset spacing is 1cm to 5cm.

[0009] The preset included angle is greater than or equal to 25°.

[0010] In any of the above technical solutions, the mounting housing is provided with two mounting slots, and the atomizing components are disposed in the mounting slots one-to-one;

[0011] Each of the atomizing components includes a soft rubber part and an atomizing plate.

The front of the atomizing plate defines the nozzle, and the back of the atomizing plate and the soft rubber part together define a liquid collection chamber.

[0016] The threading port is located between the two mounting slots, and the openings of the two mounting slots are arranged opposite each other.

[0017] In any of the above technical solutions, the mounting housing includes:

[0018] The rear cover is provided with the aforementioned mounting groove;

[0019] The front cover is connected to the rear cover. The front cover has two air guide structures that correspond one-to-one with the mounting groove. The air guide structures abut against the atomizing component and press the atomizing component into the mounting groove.

Therefore, this invention maximizes the coverage area and achieves uniform humidity distribution, ensuring the cleaning cloth is evenly wetted and the surface friction is more consistent. This not only significantly improves the cleaning efficiency and effectiveness of the window cleaning robot but also helps maintain the robot's adhesion stability on the glass surface, reducing the risk of slipping or even falling due to uneven cloth wetting. Simultaneously, this design allows the atomized liquid to be sprayed more evenly onto the surface to be cleaned, effectively reducing localized liquid accumulation and waste, thereby achieving efficient water utilization.

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] The following is a reference to the appendix. Figure 1 To be continued Figure 9 This invention describes the atomizing device 10 and the window cleaning robot according to some embodiments of the present invention.

[0039] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention proposes an atomizing device 10 for a window cleaning robot, wherein the window cleaning robot includes a square window cleaning robot, a round window cleaning robot, etc.

[0040] The atomizing device 10 includes a mounting housing 100 and two atomizing components 200. The two atomizing components 200 are respectively mounted on the mounting housing 100, forming an integral component for easy installation. For example, the atomizing components 200 include pressure atomizing components 200, rotary atomizing components 200, pneumatic atomizing components 200, ultrasonic atomizing components 200, electrostatic atomizing components 200, etc., and will not be listed in detail here.

[0041] Regarding the arrangement of the two atomizing components 200, to address the problem of uneven cloth moisture caused by concentrated spraying from existing atomizing nozzles, this invention employs a corresponding structural design to ensure that the liquid sprayed by the two atomizing components 200 does not overlap on the surface to be cleaned, thereby expanding the coverage area and making the liquid distribution more uniform. Specifically, this can be achieved through the following methods:

[0042] Implementation Method 1

[0043] The two atomizing components 200 are designed to be spaced apart, and the central axis of their nozzles has a preset distance. For example, the two atomizing components 200 are arranged side by side, and the spray direction of the two atomizing components 200 is facing forward. By controlling the central axis of the nozzles of the two atomizing components 200 to be a preset distance, the spray range can be expanded and the spray ranges can be prevented from intersecting each other.

[0044] It should be noted that the specific value of the "preset spacing" is affected by various practical factors, such as the specific specifications of the atomizing component 200 (e.g., spray angle, flow rate), the actual size of the window cleaning robot, the height of the nozzle from the surface to be cleaned, and even the spray pressure during operation. Therefore, this utility model does not impose a unique limitation on the specific values ​​of the above parameters. For those skilled in the art, a suitable value range for the corresponding product can be determined through corresponding calculations or a limited number of experiments based on actual needs, ensuring that the spray ranges of the two atomizing components 200 on the surface to be cleaned do not overlap during use. For example, the preset spacing is the distance between the central axes of the nozzles of the two atomizing components 200, wherein the value range of the preset spacing is 2 / 3 to 2 times the length of the atomizing component 200 itself, or the value range of the preset spacing is 1cm to 5cm.

[0045] Implementation Method Two

[0046] The nozzles of the two atomizing components 200 are tilted and opposite to each other, and the central axes of their nozzles form a preset angle. For example, the two atomizing components 200 are roughly distributed in a figure-eight shape. Preferably, the two atomizing components 200 are axially symmetrically distributed. In this way, the spray direction of one atomizing component 200 is towards the left front, and the spray direction of the other atomizing component 200 is towards the right front. By controlling the tilt angle of the nozzles of the two atomizing components 200, the central axes of the nozzles of the two atomizing components 200 are kept at the preset angle. This design helps to avoid the spray ranges from intersecting each other while shortening the distance between the two atomizing components 200, thereby reducing the overall size of the atomizing device 10.

[0047] It should be noted that the specific value of the "preset angle" is affected by various practical factors, such as the specific specifications of the atomizing component 200 (e.g., spray angle, flow rate), the actual size of the window cleaning robot, the height of the nozzle from the surface to be cleaned, and even the spray pressure during operation. Therefore, this utility model does not impose a unique limitation on the specific values ​​of the above parameters. For those skilled in the art, a suitable value range for the corresponding product can be determined through corresponding calculations or a limited number of experiments based on actual needs, ensuring that the spray ranges of the two atomizing components 200 on the surface to be cleaned do not overlap during use. For example, the preset angle is greater than or equal to 25°.

[0048] Implementation Method 3

[0049] Two atomizing components 200 are designed to be spaced apart by a preset interval, and their nozzles are tilted away from each other at a preset angle. Through the synergistic effect of the interval and the tilting away, the spray ranges of the two atomizing components 200 on the surface to be cleaned can be separated from each other more compactly and reliably, without intersecting.

[0050] This invention abandons the traditional approach of increasing liquid concentration in the central area through cross-spraying. Instead, it configures the atomizing components 200 with tilted, opposite directions and / or sufficient spacing. This design allows each spray to cover an independent area, fundamentally solving the problems of uneven distribution and excessive wetness of the cleaning cloth caused by cross-spraying in existing technologies. Therefore, this invention maximizes the coverage area and achieves uniform humidity distribution, ensuring the cleaning cloth is evenly wetted and its surface friction is more consistent. This not only significantly improves the cleaning efficiency and effectiveness of the window cleaning robot but also helps maintain the robot's adhesion stability on the glass surface, reducing the risk of slipping or even falling due to uneven cloth wetting. Simultaneously, this design allows the atomized liquid to be sprayed more evenly onto the surface to be cleaned, effectively reducing localized liquid accumulation and waste, thus achieving efficient water utilization.

[0051] Based on any of the above embodiments, the mounting housing 100 is provided with two mounting slots 101, and the atomizing components 200 are disposed one-to-one in the mounting slots 101. By designing and processing the spacing and tilt angle of the two mounting slots 101, the two atomizing components 200 can be installed in the corresponding mounting slots 101 to meet the corresponding preset spacing and / or preset angle. This helps to reduce the requirements for assembly accuracy and ensure the positional accuracy between the two atomizing components 200.

[0052] For example, when the atomizing component 200 is assembled into the corresponding mounting slot 101, the central axis of the nozzle of the atomizing component 200 and the central axis of the mounting slot 101 are approximately coincident. Thus, the central axes of the two mounting slots 101 can be designed to have a preset distance and / or the two mounting slots 101 are set at opposite angles, and the central axes of the mounting slots 101 form a preset angle.

[0053] In some embodiments, such as Figure 5 and Figure 6 As shown, each atomizing component 200 includes a soft rubber part 210 and an atomizing plate 220. For example, the soft rubber part 210 includes a silicone part, a rubber part, etc. The soft rubber part 210 has a through channel, and the inner wall of the channel is provided with an annular groove 211. The periphery of the atomizing plate 220 is embedded in the annular groove 211, so that the atomizing plate 220 can be clamped and fixed by the soft rubber part 210 to prevent the atomizing plate 220 from falling off. The front of the atomizing plate 220 defines a nozzle to spray mist. The back of the atomizing plate 220 and the soft rubber part 210 together define a liquid collection chamber 230. The bottom of the mounting groove 101 forms a liquid outlet 1012 opposite to the liquid collection chamber 230. The liquid collection chamber 230 can be connected to the water supply structure through the liquid outlet 1012 to realize the liquid supply to the atomizing plate 220.

[0054] In this embodiment, the liquid collection chamber 230 is built into the atomizing component 200. Compared with the solution of setting a separate liquid collection structure, the structural complexity of the atomizing component 200 is simplified. During the assembly process, the atomizing component 200 can be quickly installed and positioned as a whole unit, which effectively improves the production assembly efficiency. At the same time, the material properties of the soft rubber part 210 can ensure that the liquid collection chamber 230 itself has good sealing performance, reducing the risk of liquid leakage from the inside of the component.

[0055] The design allows the bottom surface of the flexible rubber part 210 to rest against the mounting groove 101, or a portion of the flexible rubber part 210 to extend out of the mounting groove 101 through the liquid outlet 1012. This facilitates the connection between the water supply structure and the liquid collection chamber 230, while the liquid outlet 1012 provides a clamping force on the circumference of the flexible rubber part 210, thereby improving the reliability of the connection between the flexible rubber part 210 and the mounting groove 101.

[0056] Better, such as Figure 3 and Figure 7 As shown, the design mounting groove 101 is constructed as a stepped groove, with the step surfaces of the two stepped grooves inclined in opposite directions. The outer wall of the soft rubber part 210 is adapted to the stepped groove, and the part of the soft rubber part 210 corresponding to the atomizing plate 220 abuts against the step surface.

[0057] In this embodiment, the stepped surfaces of the two stepped grooves extend in opposite directions at an angle. The portion of the soft rubber part 210 corresponding to the atomizing plate 220 directly abuts against the stepped surface. In this way, the stepped surface provides a stable and reliable reference for the tilt angle of the atomizing component 200, ensuring that the two atomizing plates 220 can accurately maintain the preset tilting opposite orientation. The matching structure between the outer wall of the soft rubber part 210 and the side wall of the stepped groove achieves effective radial limiting, preventing the atomizing component 200 from shaking or shifting in the groove, and improving the connection and fixing strength of the atomizing component 200 in the mounting groove 101.

[0058] In some embodiments, at least a portion of the wall of the liquid collecting chamber 230 is formed as an arc-shaped guide wall. The arc-shaped guide wall effectively guides the liquid flowing into the liquid collecting chamber 230, making the liquid flow smoother and more natural, effectively reducing resistance and potential eddies or splashes during liquid flow within the chamber. This smooth transition structure facilitates a more concentrated and stable flow of liquid to the area where the atomizing plate 220 is located, providing continuous and uniform wetting for the atomizing plate 220, thereby contributing to improved atomization efficiency and stability.

[0059] In some embodiments, the soft rubber part 210 is tightly fitted with the mounting groove 101. This interference contact generates continuous radial pressure, ensuring reliable fixation of the atomizing component 200 within the mounting groove 101 and effectively preventing loosening and displacement during use. Simultaneously, it reduces the risk of liquid leakage, ensuring the stability and reliability of the atomizing device 10 during operation.

[0060] In some embodiments, such as Figure 3 , Figure 4 and Figure 7As shown, the mounting housing 100 also has a liquid supply pipe 102. The liquid outlets 1012 of the two mounting slots 101 are respectively connected to the liquid supply pipe 102. The liquid supply pipe 102 is configured to be connected to the water supply structure. This enables a single pipe to stably supply liquid to the liquid collection chambers 230 of the two atomizing components 200 at the same time. On the one hand, it effectively simplifies the layout of the external water supply pipeline, simplifying the multi-step operation of connecting two independent atomizing units in the traditional solution into a single-step operation of connecting the liquid supply pipe 102 at one time, which significantly improves the assembly efficiency and reduces the connection complexity. On the other hand, the unified liquid supply source and balanced flow channel design help maintain the basic consistency of the hydraulic pressure at the inlet of the two atomizing components 200, thereby providing a continuous and similar flow rate of liquid supply to both, making their spray volume stable, ensuring that the two atomizing components 200 can produce uniform spray output, and avoiding the problem of uneven dryness and wetness of the wiping area caused by the difference in liquid supply.

[0061] In some embodiments, such as Figure 5 and Figure 8 As shown, the mounting housing 100 is provided with a wire passage 103, and each mounting groove 101 has a through-hole 1013 on its side wall. The outer side wall of the soft rubber part 210 is provided with a protrusion 212, which is engaged with the through-hole 1013. The atomizing plate 220 is connected to a wire, which passes through the protrusion 212 and exits through the wire passage 103.

[0062] By engaging the groove 212 on the soft rubber part 210 with the through-hole 1013 on the side wall of the mounting groove 101, the assembly reliability of the atomizing component 200 is significantly enhanced while achieving neat wiring. Specifically, the groove 212 provides a protected dedicated channel for the wires of the atomizing plate 220, allowing them to pass through the groove 212 in an orderly manner to the wire through-hole 103, effectively preventing wire mess, wear, or loosening, and ensuring the long-term stability of the electrical connection. At the same time, the engagement between the groove 212 and the through-hole 1013 constitutes a reliable mechanical interlock, effectively limiting the circumferential and radial movement of the atomizing component 200, preventing it from rotating or shifting freely within the mounting groove 101, and avoiding component loosening problems that may be caused by vibration or other factors.

[0063] Furthermore, the cable entry port 103 is located between the two mounting slots 101, and the through-holes 1013 of the two mounting slots 101 are arranged opposite each other. By placing the cable entry port 103 in the center between the two mounting slots 101 and arranging the through-holes 1013 of the two mounting slots 101 opposite each other, the wiring structure is further optimized, so that the wires led out from the two atomizing components 200 can converge to the cable entry port 103 in the middle in a straight line with the shortest path, forming a natural and orderly parallel layout of two wires, avoiding the phenomenon of wires crossing and twisting or excessive bending in the housing.

[0064] In some embodiments, such as Figure 8and Figure 9 As shown, the mounting housing 100 includes a rear cover 110 and a front cover 120. The rear cover 110 is provided with a mounting groove 101. The front cover 120 is connected to the rear cover 110. The front cover 120 is constructed with two air guide structures 121 that correspond one-to-one with the mounting groove 101. For example, the air guide structure 121 is horn-shaped. The air guide structure 121 abuts against the atomizing component 200 and presses the atomizing component 200 into the mounting groove 101.

[0065] For example, the back cover 110 and the front cover 120 can be connected by a structure such as a snap, a slot, or a screw.

[0066] The guide shroud structure 121 on the front cover 120 achieves both airflow guidance and fixation. Corresponding to the nozzle of the atomizing component 200, the guide shroud structure 121 can converge and directionally guide the water mist generated by the atomizing plate 220, making the spray pattern more concentrated and effectively reducing disordered diffusion of the mist. This further ensures that the spray ranges of the two atomizing components 200 are clearly separated on the surface to be cleaned, avoiding mutual interference and overlap. Simultaneously, when the front cover 120 and the rear cover 110 are closed, the guide shroud structure 121 directly abuts against and presses against the atomizing component 200, stably pushing it into the mounting groove 101, forming a reliable axial fixation. This enhances the stability of the atomizing component 200 in vibration environments and effectively prevents it from loosening or shifting.

[0067] More preferably, the soft rubber part 210 of the atomizing component 200 has a first end face and a second end face. The flow guide structure 121 acts on the first end face so that the second end face abuts against the mounting groove 101. The end face of the protrusion 212 through which the wire passes through the soft rubber part 210 is flush with the first end face. The flow guide structure 121 acts on the first end face and the end face of the protrusion 212 to further prevent leakage.

[0068] Furthermore, the front cover 120 includes a faceplate 122 and a guide shroud structure 121 that protrudes rearward from the front side of the faceplate 122. The rear cover 110 has a groove structure 111 with an opening 112 at one end. The bottom of the groove structure 111 protrudes rearward to form a mounting groove 101. The guide shroud structure 121 extends into the groove structure 111, and the faceplate 122 seals the opening 112. By designing the guide shroud to protrude rearward from the front cover 120 and embed itself in the groove of the rear cover 110, the front side of the atomizing device 10 is mainly composed of the plane of the front cover 120, presenting a simple and flat appearance. This not only improves the aesthetics of the product but also effectively reduces external protrusions, avoiding collisions and interference with obstacles such as window frames during cleaning. The guide shroud is deeply embedded in the groove, allowing the spray convergence and guidance process to be completed inside the device, optimizing the use of internal space and making the overall structure more compact. When the front cover 120 and the rear cover 110 are closed, the front cover 122 forms another sealing barrier against the recess opening 112, which helps prevent moisture or dust from entering the housing and protects the internal electrical components. This nested structure also makes the connection between the front cover 120 and the rear cover 110 more stable, enhancing the rigidity of the overall device.

[0069] More specifically, the groove bottom of the groove structure 111 is formed as two inclined bottom walls that are inclined in opposite directions. The inclined bottom walls are inclined in the same direction as the corresponding step surface, thereby increasing the installation space of the fairing structure 121.

[0070] This utility model also provides a window cleaning robot, including a body and an atomizing device 10 as described above. The body has two cleaning cloths, and the atomizing device 10 is disposed on the body, with the two atomizing components 200 of the atomizing device 10 corresponding one-to-one with the cleaning cloths.

[0071] The specific structure and effect of the window cleaning robot provided by this utility model can be referred to the above-mentioned atomizing device 10, and will not be repeated here.

[0072] More specifically, the window cleaning robot has an atomizing device 10, which is located on one side of the body in the direction of travel. This allows one atomizing component 200 to spray towards the left front of the window cleaning robot, and the other to spray towards the right front of the window cleaning robot. This expands the spraying range of the atomizing device 10 while preventing the spraying ranges of the two atomizing components 200 from intersecting, resulting in a more uniform spray.

[0073] Of course, the window cleaning robot can also be designed with two atomizing devices 10, which are set on both sides of the body in the direction of movement.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
