Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of window cleaning robots, in particular to a fogging device and a window cleaning robot. BACKGROUND

[0002] A window cleaning robot, also known as an automatic window cleaner, a glass cleaning robot, an intelligent window cleaner, an intelligent window cleaner, etc., is a kind of intelligent household appliance. It can be firmly adsorbed on the glass by means of a vacuum pump or a fan device at the bottom of the robot, and then automatically detect the corner distance of the window and plan the window cleaning path with the help of artificial intelligence. The window cleaning robot generally uses the force of adsorbing on the glass to drive the cloth at the bottom of the body to wipe off the dirt on the glass. With the emergence of window cleaning robots, people can solve the problem of high-rise window cleaning and outdoor window cleaning.

[0003] With the development of technology, the window cleaning robot adopts a fogging cleaning method because of its good cleaning effect, which has become the mainstream cleaning method of the window cleaning robot. However, the above method is prone to cause the water flow to be too large when transported to the spray head due to the high water pressure in the water tank, the fogging piece cannot fog the liquid in time, and water stagnation is left on the glass, affecting the cleaning effect. CONTENT OF THE INVENTION

[0004] Therefore, it is necessary to provide a fogging device and a window cleaning robot for the existing window cleaning robot to solve the above problems.

[0005] In a first aspect, the present application provides a fogging device, which is applied to a window cleaning robot, comprising:

[0006] a water tank module configured to store liquid for fogging;

[0007] a spray head in communication with the water tank module through a first pipeline and forming a liquid guide channel, and a fogging device is arranged at the water outlet of the spray head;

[0008] a pressure reducing device arranged on the liquid guide channel, the pressure reducing device being configured to adjust the water pressure in the liquid guide channel.

[0009] The atomizing device provided in the first aspect of the present application comprises a water tank module, a spray head and a pressure reducing device. The water tank module is communicated with the spray head through a first pipeline to form a liquid guiding channel. Liquid stored in the water tank module can be delivered to the spray head through the liquid guiding channel. An atomizer is arranged at the water outlet of the spray head. The atomizer atomizes the liquid in the spray head and sprays it to the surface of the glass to be cleaned. The pressure reducing device is arranged between the water tank module and the spray head. The pressure reducing device can convert the high-pressure fluid input into the liquid guiding channel into low-pressure fluid. The water flow at the spray head can be avoided from being too large, so that part of the liquid cannot be atomized by the atomizer in time and thus water stagnation is left on the glass, thereby ensuring the cleaning effect of the window cleaning robot.

[0010] In one of the embodiments, the pressure reducing device comprises a pressure reducer arranged in the liquid guiding channel. The pressure reducer divides the liquid guiding channel into a first channel and a second channel along the direction of the water tank module towards the spray head. The pressure reducer is provided with a plurality of pressure reducing channels. The first channel is communicated with the second channel through the plurality of pressure reducing channels.

[0011] In the above-mentioned embodiments, the pressure reducer is further provided with a plurality of pressure reducing channels. After the liquid in the first channel is distributed to the plurality of pressure reducing channels, the resistance to the flow of the liquid is increased, so that the pressure of the liquid discharged through the pressure reducer is reduced. Compared with other pressure reducing valve structures, the pressure reducer structure of the present application is simple and has good pressure reducing effect, avoiding the water flow pressure being too large when delivered to the spray head.

[0012] In one of the embodiments, the pressure reducing device comprises a water guiding cotton arranged in the liquid guiding channel. The water guiding cotton extends from the water tank module towards the spray head.

[0013] In the above-mentioned embodiments, the liquid guiding channel is further provided with the water guiding cotton. When the water pressure in the liquid guiding channel is too large, the liquid flowing through the water guiding cotton increases the resistance to the transmission of the liquid in the liquid guiding channel, thereby reducing the water pressure. When the water pressure in the liquid guiding channel is small, the water guiding property of the water guiding cotton can well guide the liquid to the spray head, avoiding the situation that the atomizer is affected by the low water pressure to affect the atomization effect, and also maximizing the consumption of the liquid stored in the water tank module to avoid residue.

[0014] In one of the embodiments, the water guiding cotton and the pressure reducer cooperate to jointly adjust the water pressure in the liquid guiding channel.

[0015] In one of the embodiments, the sum of the cross-sectional areas of the plurality of pressure reducing channels is smaller than the cross-sectional area of the first pipeline.

[0016] The atomizing device in the above embodiment is further limited that the sum of the cross-sectional areas of the plurality of pressure reduction channels is less than the cross-sectional area of the first channel. Based on the above design, during the process that the liquid is discharged from the first channel to the second channel through the pressure reducer, the liquid is distributed from the large-aperture channel to the plurality of small-aperture channels, and then is discharged from the plurality of small-aperture channels and re-converges in the large-aperture channel. In the above process, the high-pressure liquid is converted into low-pressure liquid.

[0017] In one of the embodiments, at least one of the plurality of pressure reduction channels is a pressure reduction main channel, and the rest are pressure reduction sub-channels, which are distributed at the periphery of the pressure reduction main channel.

[0018] In one of the embodiments, the surface of the pressure reducer is attached to the inner wall of the first pipeline, and the surface of the pressure reducer is provided with a plurality of grooves arranged at intervals, which form the pressure reduction sub-channels.

[0019] In one of the embodiments, a buffer groove is formed inside the spray head, the water inlet of the buffer groove is communicated with the water outlet of the first pipeline, and the atomizer is arranged at the water outlet of the buffer groove. The buffer groove includes a first groove body and a second groove body, the distance between the groove bottom of the first groove body and the cleaning part in the window-cleaning robot is greater than the distance between the groove body of the second groove body and the cleaning part in the window-cleaning robot, the first groove body is communicated with the second groove body, the water inlet of the buffer groove is distributed on the first groove body, and at least part of the atomizer falls into the liquid storage range of the second groove body.

[0020] In the above embodiment, the atomizing device is further limited that a buffer groove is formed inside the spray head. Based on the cooperation of the first groove body and the second groove body, the impact of the liquid on the atomizer due to the large water flow is reduced, and the liquid stored in the second groove body can be atomized in time, which not only improves the atomizing effect, but also avoids long-term storage of the liquid in the second groove body.

[0021] In one of the embodiments, the atomizer is designed to be inclined on the buffer groove.

[0022] In the above embodiment, the atomizing device is further limited that the atomizer is arranged on the buffer groove at an inclined angle. Based on the above design, the liquid discharged from the atomizer is sprayed onto the glass area to be cleaned at a certain angle, which avoids that the liquid discharged from the atomizer is directly sprayed on the current cleaning area of the window-cleaning robot or directly sprayed on the body of the window-cleaning robot.

[0023] In one of the embodiments, the water outlet direction of the first pipeline and the liquid transmission path direction of the buffer groove are arranged at an angle, and the atomizer is distributed at one end away from the water inlet of the buffer groove.

[0024] The atomizing device in the above embodiment is further limited in that the water outlet direction of the first pipeline is arranged at an angle with the liquid transmission path direction of the buffer groove. Based on the above design, the liquid turns in the liquid guide channel, thereby increasing the water flow resistance and further reducing the pressure.

[0025] In one of the embodiments, the number of the spray heads is not less than one, the number of the pressure reducing devices is the same as the number of the spray heads, the water tank module is in communication with each of the spray heads and forms the liquid guide channels, and each of the liquid guide channels is provided with the pressure reducing device.

[0026] The atomizing device in the above embodiment is further limited in that the number of the spray heads is not less than one. When the number of the spray heads is multiple, the multiple spray heads are connected with the water tank module and form multiple liquid guide channels. Based on the multiple spray heads, the multiple cleaning areas of the glass to be cleaned can be sprayed, and the spraying efficiency is improved.

[0027] In one of the embodiments, when the window cleaning robot works, the water tank module and the spray head are sequentially distributed on the window cleaning robot from top to bottom, and the gravitational potential energy of the liquid in the water tank module is greater than that of the liquid in the spray head.

[0028] The atomizing device in the above embodiment is further limited in that when the window cleaning robot works, the horizontal height of the water tank module is higher than that of the spray head, so that the liquid in the water tank module can be transported to the spray head by gravity, without the need to set an additional conveying device such as a water pump, and the liquid stored in the water tank module can be further transported to the spray head when the window cleaning robot shakes during movement, thereby improving the rationality of the design of the atomizing device and effectively reducing the product cost.

[0029] In a second aspect, the application provides a window cleaning robot, which comprises a robot main body and the atomizing device according to any one of the above embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0048] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present application belong. Terms such as those defined in commonly used dictionaries will be interpreted as having a meaning that is the same as commonly used in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless clearly defined in various embodiments of the present application.

[0049] In one embodiment, as shown in Figures 1 to 6 An atomizing device is provided, which is applied to a window cleaning robot and includes:

[0050] A water tank module 200 configured to store liquid for atomization;

[0051] A spray head 400 in communication with the water tank module 200 through a first pipe 500 and forming a liquid guide channel 100, and an atomizer 600 arranged at a water outlet of the spray head 400;

[0052] A pressure reducing device 800 arranged on the liquid guide channel 100 and configured to adjust the water pressure in the liquid guide channel 100.

[0053] The window cleaning robot can include a robot body 20 and an atomizing device 10. The atomizing device 10 can be used to atomize cleaning liquid. The robot body 20 can include a housing, an adsorption module, a walking unit, a sensor module, a control device, and a cleaning piece. The adsorption module can adopt a vacuum adsorption mode, and a local negative pressure is generated by a centrifugal fan or a vacuum pump to make the robot adhere to the glass surface. The walking unit can drive the robot to walk on the glass surface by driving the transmission structure through the driving motor. The sensor module senses the surrounding environment through laser or infrared or ultrasonic waves to determine the position and attitude of the robot, thereby controlling the movement of the robot. The cleaning piece can be one or a combination of a cloth or a brush. The control device can control the walking unit, the adsorption module, and the atomizing device 10 according to the preset program and the signals collected by the sensor module.

[0054] The water tank module 200 can be used to store liquids. The water tank module 200 can be a shell structure made of transparent or opaque material. For example, the water tank module 200 is a transparent plastic shell structure. The liquid stored in the water tank module 200 can be water, cleaning fluid, or a mixture of water and cleaning fluid.

[0055] The atomizer 600 is used to atomize the liquid in the nozzle 400 and spray it onto the glass surface. The atomizer 600 can be installed at the outlet of the nozzle 400. When the liquid in the water tank module 200 is transported to the nozzle 400 through the first pipe 500, the atomizer 600 atomizes the liquid in the nozzle 400. It should be noted that the liquid in the water tank module 200 can be transported to the nozzle 400 by a water pump or by utilizing a liquid drop. Additionally, the atomizer 600 can be an ultrasonic atomizing plate.

[0056] The pressure reducing device 800 can be used to convert high-pressure fluid into low-pressure fluid and output it to the nozzle 400. The pressure reducing device 800 controls the flow rate by narrowing the fluid passage during flow, thereby reducing the pressure. It should be noted that in some other embodiments, the pressure reducing device 800 can also control the opening and closing degree of the valve body through a pressure reducing valve, adjusting the cross-sectional area of ​​the fluid passage to reduce the velocity of the fluid passing through the pressure reducing valve, thus achieving fluid pressure regulation.

[0057] The atomizing device of this application includes a water tank module 200, a nozzle 400, and a pressure reducing device 800. The water tank module 200 is connected to the nozzle 400 through a first pipe 500 to form a liquid guiding channel 100. The liquid stored in the water tank module 200 can be transported to the nozzle 400 through the liquid guiding channel 100. An atomizer 600 is provided at the outlet of the nozzle 400. The atomizer 600 atomizes the liquid in the nozzle 400 and sprays it onto the glass surface to be cleaned. By providing a pressure reducing device 800 between the water tank module 200 and the nozzle 400, the pressure reducing device 800 can convert the high-pressure fluid input to the liquid guiding channel 100 into a low-pressure fluid. This can prevent the water flow at the nozzle 400 from being too large, which would cause some liquid to not be atomized by the atomizer 600 in time and leave water residue on the glass, thereby ensuring the cleaning effect of the window cleaning robot.

[0058] In some embodiments, such as Figure 2 As shown, the pressure reducing device 800 includes a pressure reducing device 81, which is disposed in the liquid guiding channel 100. The pressure reducing device 81 divides the liquid guiding channel 100 into a first channel 110 and a second channel 120 along the direction from the water tank module 200 toward the nozzle 400. The pressure reducing device 81 has multiple pressure reducing channels 801, and the first channel 110 is connected to the second channel 120 through the multiple pressure reducing channels 801 respectively.

[0059] In the above embodiments, the pressure reducer 81 is further provided with multiple pressure reducing channels 801. After the liquid is distributed from the first channel 110 to the multiple pressure reducing channels 801, the resistance to the liquid flow increases, thereby reducing the pressure of the liquid discharged through the pressure reducer 81. Compared with other pressure reducing valve structures, the pressure reducer 81 of this application has a simple structure, good pressure reduction effect, and avoids excessive water pressure delivered to the nozzle 400.

[0060] The pressure reducer 81 can be a metal columnar structure or a non-metal columnar structure. For example, the pressure reducer 81 is a metal columnar structure, and it has multiple pressure reducing channels 801 along its length. The pressure reducer 81 can divide the liquid guiding channel 100 into a first channel 110 and a second channel 120. The liquid coming out of the water tank module 200 is first transported into the first channel 110, and then transported to the second channel 120 after passing through the pressure reducer 81. The pressure reducer 81 may include multiple pressure reducing channels 801. The liquid in the first channel 110 is transported to the second channel 120 after passing through multiple pressure reducing channels 801. Based on the fact that the liquid in the first channel 110 is distributed to multiple pressure reducing channels 801 when flowing through the pressure booster, the resistance of the liquid flowing through the pressure reducer 81 is increased, thus increasing the pressure of the liquid discharged through the pressure reducer 81.

[0061] In some embodiments, such as Figure 1 As shown, the pressure reducing device 800 also includes a water-guiding cotton (not shown in the figure), which is disposed in the liquid guiding channel 100 and extends from the water tank module 200 toward the nozzle 400.

[0062] In the above embodiments, a water-guiding cotton is further provided within the liquid guiding channel 100. The water-guiding cotton not only increases the resistance to liquid transmission within the liquid guiding channel 100, thus reducing pressure, but also guides water flow to the nozzle 400 when the liquid level in the water tank module 200 is low, improving utilization. This application, through the cooperation of the water-guiding cotton and the pressure reducer 81, can significantly reduce the liquid pressure input to the nozzle 400, enabling the atomizer 600 to atomize the liquid in a timely manner.

[0063] The water-wicking cotton can be, but is not limited to, cotton or wood fiber. For example, the water-wicking cotton has a columnar sponge structure. Specifically, when the water pressure in the liquid channel 100 is too high, the water-wicking cotton will absorb some water, causing the water flow speed to slow down. The liquid flowing over the water-wicking cotton increases the resistance to liquid transmission in the liquid channel 100, thereby reducing the water pressure. When the water pressure in the liquid channel 100 is low, the water-wicking cotton can effectively guide the liquid to the nozzle 400, which not only avoids the atomizer's atomization effect being affected by low water pressure, but also maximizes the consumption of the liquid stored in the water tank module 200, avoiding residue.

[0064] Further, the water guide cotton can extend from the water outlet of the water tank module 200 to the water inlet of the spray head 400.

[0065] In some embodiments, the water guide cotton and the pressure reducer cooperate to jointly regulate the water pressure in the liquid guide channel 100. Specifically, the water guide cotton extends from the water outlet of the water tank module 200 through one of the pressure reduction channels 801 and to the spray head 400.

[0066] Further, the number of water guide cottons can be more than one, for example, the number of water guide cottons is two, and both of the water guide cottons extend from the water outlet of the water tank module 200 through two pressure reduction channels 801 to the water inlet of the spray head 400.

[0067] In some embodiments, as shown in Figure 2 and Figure 3 The sum of the cross-sectional areas of the plurality of pressure reduction channels 801 is less than the cross-sectional area of the first channel 110.

[0068] In the above embodiments, it is further limited that the sum of the cross-sectional areas of the plurality of pressure reduction channels 801 is less than the cross-sectional area of the first channel 110. Based on the above design, during the process of discharging the liquid from the first channel 110 to the second channel 120 through the pressure reducer 81, the liquid is distributed from the large-diameter channel to the plurality of small-diameter channels, and then discharged from the plurality of small-diameter channels and re-converged in the large-diameter channel. In the above process, the high-pressure liquid is converted into low-pressure liquid.

[0069] In some embodiments, as shown in Figure 2 and Figure 3 At least one of the plurality of pressure reduction channels 801 is a main pressure reduction channel, and the rest are auxiliary pressure reduction channels, which are distributed in the periphery of the main pressure reduction channel.

[0070] Among them, the plurality of pressure reduction channels 801 opened on the pressure reducer 81, for example, the number of pressure reduction channels 801 is four, one of which is a main pressure reduction channel, and the other three are auxiliary pressure reduction channels. The auxiliary pressure reduction channels can be distributed in the periphery of the main pressure reduction channel as the center of the circle on the pressure reducer 81. The cross-sectional area of the main pressure reduction channel can be greater than the cross-sectional area of the auxiliary pressure reduction channel, so that most of the liquid in the first channel 110 is transported from the main pressure reduction channel to the second channel 120, and a small part of the liquid is transported from the plurality of auxiliary pressure reduction channels to the second channel 120. Further, the water guide cotton can extend from the water outlet of the water tank module 200 through the main pressure reduction channel and then to the water inlet of the spray head 400.

[0071] It should be noted that in other embodiments, the cross-sectional area of the main pressure reduction channel can also be consistent with the cross-sectional area of the auxiliary pressure reduction channel.

[0072] In some embodiments, as shown in Figure 2 andFigure 3 As shown, the surface of the pressure reducer 81 is attached to the inner wall of the first pipeline 500, and the surface of the pressure reducer 81 is provided with a plurality of recesses 810 arranged at intervals, and the recesses 810 form the pressure reduction sub-passage.

[0073] The surface of the pressure reducer 81 is attached to the inner wall of the first pipeline 500, and the friction between the pressure reducer 81 and the first pipeline 500 is used to fix the pressure reducer 81, so that the pressure reducer 81 does not move in the first pipeline 500, affecting the pressure reduction effect or causing pipeline blockage. In addition, the surface of the pressure reducer 81 is provided with a plurality of recesses 810, based on the attachment of the surface of the pressure reducer 81 to the inner wall of the first pipeline 500, the recesses 810 and the inner wall of the first pipeline 500 form the above-mentioned pressure reduction sub-passage, so as to ensure the size of the cross-sectional area of the pressure reduction sub-passage and the pressure reduction main passage, avoid the caliber of the pressure reduction sub-passage and the pressure reduction main passage is too small, resulting in the liquid flow entering the nozzle 400 is too small, affecting the atomization effect.

[0074] In some embodiments, as shown in Figure 4 The buffer groove 410 is formed inside the nozzle 400, the water inlet of the buffer groove 410 is communicated with the water outlet of the first pipeline 500, and the atomizer 600 is arranged at the water outlet of the buffer groove 410;

[0075] The buffer groove 410 includes a first groove body 411 and a second groove body 412, the distance between the groove bottom of the first groove body 411 and the cleaning part of the window cleaning robot is greater than the distance between the groove body of the second groove body 412 and the cleaning part of the window cleaning robot, the first groove body 411 is communicated with the second groove body 412, the water inlet of the buffer groove 410 is distributed on the first groove body 411, and the atomizer 600 at least partially falls into the liquid storage range of the second groove body 412.

[0076] The above-mentioned embodiment further limits that the buffer groove 410 is provided inside the nozzle 400, based on the cooperation of the first groove body 411 and the second groove body 412, the impact of the liquid on the atomizer 600 when the water flow is too large is reduced, and by at least part of the atomizer 600 falling into the second groove body 412, the liquid stored in the second groove body 412 can be atomized in time, not only improving the atomization effect, but also avoiding the liquid being stored in the second groove body 412 for a long time.

[0077] The buffer groove 410 can reduce the pressure of the liquid delivered to the atomizer 600. Specifically, the buffer groove 410 can include a first groove body 411 and a second groove body 412 in communication with each other, and the first groove body 411 and the second groove body 412 form a groove structure similar to a stepped structure. Based on the distance between the groove bottom of the first groove body 411 and the glass being greater than the distance between the second groove body 412 and the glass, when the liquid is delivered from the first pipeline 500 to the buffer groove 410, the liquid first enters the first groove body 411, and when the liquid flow is too large, part of the liquid will fall into the second groove body 412, reducing the impact of the liquid input through the first pipeline 500 on the atomizer 600. In addition, based on the atomizer 600 at least partially falling into the liquid storage range of the second groove body 412, that is, when the liquid flow is too large, part of the liquid falls into the second groove body 412, the atomizer 600 can atomize the liquid in the second groove body 412, thereby improving the atomization efficiency.

[0078] In some embodiments, as shown in FIG. 6, the atomizer 600 is designed to be inclined on the buffer groove 410. Figure 4

[0079] In the above embodiment, the atomizer 600 is further limited to be arranged on the buffer groove 410 at an inclined angle. Based on the above design, the liquid discharged from the atomizer 600 is sprayed on the glass area to be cleaned at a certain angle, avoiding the liquid discharged from the atomizer 600 directly on the area currently cleaned by the window cleaning robot or directly sprayed on the body of the window cleaning robot.

[0080] In some embodiments, as shown in FIG. 6, the water outlet direction of the first pipeline 500 is arranged at an angle with the liquid transmission path direction of the buffer groove 410, and the atomizer 600 is distributed at one end away from the water inlet of the buffer groove 410. Figure 4

[0081] In the above embodiment, the water outlet direction of the first pipeline 500 is further limited to be arranged at an angle with the liquid transmission path direction of the buffer groove 410. Based on the above design, the liquid makes a turn in the liquid guide channel 100, thereby increasing the water flow resistance and reducing the pressure.

[0082] In the above embodiment, the water outlet direction of the first pipeline 500 can be arranged at an angle with the liquid transmission path of the buffer groove 410. For example, the water outlet direction of the first pipeline 500 is perpendicular to the liquid transmission path direction of the buffer groove 410. The liquid entering the buffer groove 410 from the first pipeline 500 first contacts the groove wall of the buffer groove 410, and then changes the direction of the liquid flow, thereby reducing the flow speed of the liquid, so that the water flow delivered to the atomizer 600 is not too large, ensuring that the liquid can be atomized in time.

[0083] In some embodiments, as shown in FIG. 6, the water outlet direction of the first pipeline 500 is arranged at an angle with the liquid transmission path direction of the buffer groove 410, and the atomizer 600 is distributed at one end away from the water inlet of the buffer groove 410. Figure 1 ,​​Figure 5 and Figure 6 As shown, there is at least one nozzle 400, and the number of pressure reducing devices 800 is the same as the number of nozzles 400. The water tank module 200 is connected to at least one nozzle 400 to form a liquid guiding channel 100, and each liquid guiding channel 100 is equipped with a pressure reducing device 800.

[0084] In the above embodiments, the number of nozzles 400 is further limited to not less than one. When there are multiple nozzles 400, the multiple nozzles 400 are respectively connected to the water tank module 200 to form multiple liquid guiding channels 100. Based on the multiple nozzles 400, multiple glass cleaning areas to be cleaned can be sprayed, thereby improving spraying efficiency.

[0085] The number of nozzles 400 can be no less than one. For example, there can be two nozzles 400, and correspondingly, there can also be two pressure reducing devices 800. The two nozzles 400 are connected to the water tank module 200 through two first pipes 500, forming two liquid guiding channels 100, each of which is equipped with a pressure reducing device 800. The two nozzles 400 can be distributed at intervals at the left and right ends or the top and bottom ends of the window cleaning robot, thereby increasing the atomization range. When there is only one water tank module 200, specifically, the water tank module 200 is arc-shaped. When the window cleaning robot is working, the arc-shaped convex direction of the water tank module 200 is opposite to the direction of gravity. The water tank module 200 has two outlets, which are symmetrically distributed at the bottom. Under the action of gravity, the liquid in the water tank module 200 is evenly distributed to the two outlets of the water tank module 200. In other embodiments, the number of nozzles 400 and pressure reducing devices 800 may be three, four, or more.

[0086] It should be noted that in some embodiments, the number of water tank modules 200 can be two or more. Specifically, when there is one water tank module 200, two nozzles 400 are connected to one water tank module 200 at the same time, and when there are two water tank modules 200, two nozzles 400 are connected to two water tank modules 200 respectively.

[0087] In some embodiments, such as Figure 1 As shown, when the window cleaning robot is working, the water tank module 200 and the spray nozzle 400 are distributed on the window cleaning robot from top to bottom. The gravitational potential energy of the liquid in the water tank module 200 is greater than that of the liquid in the spray nozzle 400.

[0088] In the above embodiment, the water tank module 200 is further defined to have a height higher than the height of the spray head 400, so that the liquid in the water tank module 200 can be delivered to the spray head 400 by gravity, without the need of an additional delivery device such as a water pump, and the liquid in the water tank module 200 can be further delivered to the spray head 400 when the window cleaning robot shakes during movement, thus improving the rationality of the design of the atomizing device 10 and effectively reducing the product cost.

[0089] As shown in Figure 1 The present application also provides a window cleaning robot, which comprises a robot body 20 and an atomizing device as described above.

[0090] The specific description of the robot body 20 can refer to the description of the above embodiment, which will not be repeated here.

[0091] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0092] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
