[0040] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0041] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0042] The terms "parallel," "perpendicular," and "identical" as used in this disclosure include the strictly defined meanings of "parallel," "perpendicular," and "identical," as well as cases where "approximately parallel," "approximately perpendicular," and "approximately identical" include some degree of error. Taking into account measurement and errors associated with the measurement of a specific quantity (i.e., limitations of the measurement system), they represent the acceptable deviation range for a specific value as determined by a person skilled in the art. In embodiments of this disclosure, "center" can include a strictly geometrically centered location and an approximate center location within a small area surrounding the geometrically centered location. For example, "approximately" can mean within one or more standard deviations, or within 10% or 5% of the value.

[0043] In some cleaning devices, a water pump can be used to pressurize a liquid, causing it to be sprayed outwards through small orifices on a nozzle. However, in their research, the inventors of this application discovered that because the diameter of the orifices is small, such as less than 0.5 mm, the orifices are prone to clogging when impurities are present in the liquid, thus affecting the water spraying effect. Furthermore, liquids such as water may produce scale, which can also cause the orifices to become clogged.

[0044] In other cleaning devices, the high-frequency vibration of an ultrasonic plate can be used to allow liquid to pass through micropores on the plate, forming micron-sized water droplets, which are then accelerated by the ultrasonic plate to form a water mist. However, in their research, the inventors of this application also discovered that the micropores on the ultrasonic plate are micron-sized, making them more prone to clogging. If condensed water droplets flow back onto the ultrasonic plate, the resulting large droplets can weaken the vibration effect of the ultrasonic waves, leading to a reduced spray volume or even no spray at all. Furthermore, because the water mist sprayed from the ultrasonic plate consists of micron-sized droplets, it is highly susceptible to interference from external airflow, such as being blown away or evaporating, resulting in a large number of water droplets not landing on the surface to be cleaned, thus affecting cleaning efficiency.

[0045] At least one embodiment of this disclosure provides a water spray assembly, which includes a main body and a diverter. The main body includes a first annular wall, a second annular wall, and a flow guide channel; at least a portion of the second annular wall is located within a space surrounded by the first annular wall; a portion of the space surrounded by the first annular wall located outside the second annular wall forms a first air duct, and the first air duct includes an air inlet and an air outlet opposite each other in an extension direction along the axis of the first annular wall; the diverter is at least a portion located within the space surrounded by the second annular wall; the diverter includes a plurality of diverter channels; wherein the plurality of diverter channels are configured to communicate with the flow guide channel to divert liquid in the flow guide channel, and the first air duct is configured to deliver airflow from the air inlet to the air outlet, so that the liquid flowing out of the plurality of diverter channels is sprayed outward from the main body.

[0046] At least one embodiment of this disclosure provides a cleaning module, including the water spray assembly, cleaning disc assembly, and air guide structure described in the above embodiments. The cleaning disc assembly surrounds an adsorption space configured to generate negative pressure, and the air guide structure connects the adsorption space and the air inlet.

[0047] At least one embodiment of this disclosure provides a cleaning device, including the cleaning module and adsorption element of the above embodiments, wherein the adsorption element is configured to provide negative pressure to the adsorption space.

[0048] In at least one embodiment of the water spray assembly, cleaning module, and cleaning device provided in this disclosure, the liquid in the guide channel is diverted by multiple diversion channels, and the airflow in the first air duct is transported from the air inlet to the air outlet, thereby causing the liquid flowing out from the multiple diversion channels to be sprayed onto the outside of the main body. By providing a first annular wall and a second annular wall, the cross-sectional area of ​​the air duct can be reduced, thereby accelerating the airflow in the first air duct as it flows towards the air outlet. Therefore, the accelerated high-speed airflow can be used to smoothly spray the diverted liquid. Furthermore, due to the diversion channels, compared to solutions using small spray holes, the water spray assembly is less prone to clogging. Moreover, the liquid sprayed from the water spray assembly has a high utilization rate, which is beneficial for improving cleaning effect and efficiency.

[0049] The water spray assembly, cleaning module, and cleaning device are described below with reference to the accompanying drawings and through some embodiments.

[0050] FIG. 1 This is an exploded schematic diagram of a water spray assembly provided as an example in at least one embodiment of the present disclosure. FIG. 2 This is a schematic cross-sectional view of a water spray assembly provided in at least one embodiment of this disclosure. For example, FIG. 1 The water spray assembly shown is FIG. 2 The water spray assembly shown can be the same water spray assembly.

[0051] refer to FIG. 1 andFIG. 2 At least one embodiment of this disclosure provides a water spray assembly, including a main body 100 and a flow divider 200. The main body 100 includes a first annular wall 110, a second annular wall 120, and a flow channel 130, with at least a portion of the second annular wall 120 located within the space surrounded by the first annular wall 110. For example, refer to… FIG. 2 The second annular wall 120 may be entirely located within the space surrounded by the first annular wall 110. However, this disclosure does not limit this; for example, only a portion of the second annular wall 120 may be located within the space surrounded by the first annular wall 110, while another portion may be located outside the space surrounded by the first annular wall 110. The specific arrangement of the first annular wall 110 and the second annular wall 120 will be described in detail later and will not be repeated here.

[0052] refer to FIG. 1 and FIG. 2 The portion of the space enclosed by the first annular wall 110 located outside the second annular wall 120 forms a first air duct 101, and the first air duct 101 includes an axis along the first annular wall 110 (e.g., reference to...). FIG. 2 The air inlet 1011 and air outlet 1012 are opposite each other in the extension direction of the axis AX shown. At least a portion of the diverter 200 is located within the space surrounded by the second annular wall 120. For example, refer to FIG. 2 The diverter 200 can be entirely located within the space surrounded by the second annular wall 120. However, this disclosure does not limit this. For example, only a portion of the diverter 200 may be located within the space surrounded by the second annular wall 120, while another portion may be located outside the space surrounded by the second annular wall 120. The specific arrangement of the diverter 200 and the second annular wall 120 will be described in detail later and will not be repeated here.

[0053] FIG. 3A for FIG. 1 A schematic diagram of the flow divider in the water spray assembly shown.

[0054] refer to FIG. 1 , FIG. 2 and FIG. 3A The diversion component 200 includes multiple diversion channels 210. The multiple diversion channels 210 are configured to communicate with the guide channel 130 to divert liquid in the guide channel 130. The first air duct 101 is configured to deliver airflow from the air inlet 1011 to the air outlet 1012 so that the liquid flowing out of the multiple diversion channels 210 is sprayed out of the main body 100.

[0055] refer to FIG. 3A ,For example, FIG. 3A The diagram schematically shows 12 diversion channels 210 provided on the diversion component 200. However, this disclosure does not limit the number of diversion channels 210.

[0056] refer to FIG. 1 to FIG. 3A In at least one embodiment of the water spray assembly provided in this disclosure, the liquid in the guide channel 130 is diverted by multiple diversion channels 210, and the airflow in the first air duct 101 is transported from the air inlet 1011 to the air outlet 1012, thereby causing the liquid flowing out from the multiple diversion channels 210 to be sprayed outside the main body 100. By providing the first annular wall 110 and the second annular wall 120, the cross-sectional area of ​​the air duct can be reduced, thereby accelerating the airflow in the first air duct 101 as it flows towards the air outlet 1012. Therefore, the accelerated high-speed airflow can be used to smoothly spray the diverted liquid. Furthermore, due to the diversion channels 210, compared to the solution using small spray holes, the water spray assembly is less prone to clogging. Moreover, the liquid sprayed from the water spray assembly has a high utilization rate, which is beneficial for improving cleaning effect and efficiency.

[0057] refer to FIG. 1 to FIG. 3A In at least one embodiment of this disclosure, the water spray assembly does not need to break the liquid into tiny droplets. Instead, it uses a diversion channel 210 to divert the liquid, and then a high-speed airflow within the first air duct 101 sprays the diverted liquid outwards. Compared to other examples that use smaller nozzles to achieve the spray effect, the size of the diversion channel 210 in the water spray assembly can be designed to be relatively large. This reduces the risk of liquid clogging the diversion channel 210, extends the service life of the water spray assembly, eliminates the need for frequent replacements, and provides a better user experience.

[0058] Furthermore, compared to the tiny droplets sprayed in other examples, the liquid sprayed from the water spray assembly has stronger resistance to disturbances, easily settles on the surface to be cleaned due to inertia, and does not evaporate too quickly. For example, compared to droplet-spraying solutions, the water spray assembly has relatively lower requirements for the operating environment, and is less affected by environmental factors such as wind speed, temperature, and humidity. Therefore, the liquid sprayed from the water spray assembly has a higher utilization rate, which helps improve the cleaning effect and efficiency of the cleaning module or device using this water spray assembly.

[0059] For example, depending on the actual work scenario, the surface to be cleaned can be diverse. For instance, the surface to be cleaned can include window surfaces, walls, floors, and other surfaces that need to be cleaned.

[0060] For example, the liquid sprayed in the water spray assembly may include water or cleaning fluid. It is understood that the liquid flowing into the water spray assembly can be selected according to actual needs, and this disclosure does not limit this selection.

[0061] refer to FIG. 2For example, the extension direction of the axis of the second annular wall 120 intersects the extension direction of the guide channel 130. As a result, it is easy to guide the liquid to the diversion channel 210.

[0062] refer to FIG. 2 For example, the extension direction of the axis of the second annular wall 120 and the extension direction of the guide channel 130 may not be perpendicular to each other, which can save space and facilitate the arrangement of other parts. Moreover, it is also conducive to thinner and lighter designs. For example, when the water spray assembly is used in the cleaning module and cleaning device, it is beneficial to reduce the thickness of the cleaning module and cleaning device.

[0063] However, this disclosure is not limited thereto. For example, the extension direction of the axis of the second annular wall can be perpendicular to the extension direction of the flow channel, which is beneficial for shortening the liquid flow path and for ease of processing.

[0064] refer to FIG. 2 For example, the flow channel 130 may be generally tubular and may pass through the first annular wall 110 and extend into the space surrounded by the second annular wall 120.

[0065] refer to FIG. 2 For example, the flow channel 130, the first annular wall 110, and the second annular wall 120 can be integrally formed. However, this disclosure is not limited thereto. For example, the flow channel 130, the first annular wall 110, and the second annular wall 120 can also be separate parts, and this disclosure does not limit them in this regard.

[0066] refer to FIG. 1 to FIG. 3A In some examples, the diverter 200 includes a first portion P1 and a second portion P2, with the second portion P2 being further away from the air inlet 1011 than the first portion P1. An annular flow channel 01 is defined between the first portion P1 and the second annular wall 120 of the diverter 200. Multiple diverting channels 210 are disposed in the second portion P2 of the diverter 200, and the annular flow channel 01 connects the guide channel 130 and the multiple diverting channels 210. Thus, liquid flowing in from the guide channel 130 flows through the annular flow channel 01 into the multiple diverting channels 210, which facilitates uniform liquid distribution.

[0067] refer to FIG. 3A For example, the annular flow channel 01 can extend circumferentially in the flow divider 200, thereby guiding the flow of liquid. For example, multiple flow dividers 210 can be distributed at intervals or evenly in the circumferential direction of the flow divider 200. Liquid flowing in from the guide channel 130 can easily enter the multiple flow dividers 210 under the guidance of the annular flow channel 01, which is beneficial for uniform flow distribution.

[0068] refer to FIG. 1 to FIG. 3AIn some examples, the surface of the second portion P2 of the diverter 200 includes a plurality of protrusions 220, which are spaced apart circumferentially in the diverter 200, forming a diverter channel 210 between adjacent protrusions 220. By setting the surface of the second portion P2 to include a plurality of protrusions 220, the diverter channel 210 can be formed using the protrusions 220. Simultaneously, when the protrusions 220 protrude relative to the surface of the first portion P1, an annular flow channel 01 is formed between the outer wall surface of the first portion P1 and the inner wall surface of the second annular wall 120. This simplifies the manufacturing process of the diverter 200 and reduces processing costs.

[0069] refer to FIG. 1 and FIG. 2 For example, the boundary between the first part P1 and the second part P2 may include the edge of the protrusion 220 near the air inlet 1011.

[0070] Of course, this disclosure is not limited to this. For example, in some other examples, an annular flow channel with a groove structure may also be provided on the first part. As long as the annular flow channel can be used to guide the liquid flowing out of the guide channel to multiple branch channels, this disclosure does not limit the shape, structure, etc. of the annular flow channel.

[0071] refer to FIG. 3A and combined FIG. 2 In some examples, in the cross-section of the diverter 200 cut by a plane, the cross-sectional areas of any two diverter channels 210 are approximately equal. The diverter 200 has an axis, and the plane is perpendicular to the axis of the diverter 200. Thus, the cross-sectional areas of all diverter channels 210 are designed to be approximately equal, and the flow rates of liquid flowing out from multiple diverter channels 210 are approximately the same, which helps to improve the uniformity of water discharge from the diverter 200 in its circumferential direction.

[0072] refer to FIG. 3A and combined FIG. 2 In some examples, the area of ​​the opening on the side of the diversion channel 210 closer to the air inlet 1011 is larger than the area of ​​the opening on the side of the diversion channel 210 furthest from the air inlet 1011. By designing the area of ​​the outlet of the diversion channel 210, i.e., the opening on the side furthest from the air inlet 1011, to be smaller, it is beneficial to improve the water discharge effect of the water spray assembly. In addition, designing the openings at both ends of the diversion channel 210 differently during the manufacturing process of the diversion component 200 can also make demolding smoother.

[0073] refer to FIG. 3A and combined FIG. 2For example, the cross-sectional area of ​​the diversion channel 210 can gradually decrease along its extension direction and in the direction away from the air inlet 1011. This allows for acceleration of the liquid flowing through the diversion channel 210 by reducing its cross-sectional area. Furthermore, after the diversion component 200 is assembled with the main body 100, the larger opening area of ​​the diversion channel 210 near the guide channel 130 reduces the risk of internal blockage in the water spray assembly.

[0074] Of course, this disclosure does not impose any limitations on this. In other examples, the cross-sectional area of ​​the diversion channel may also be approximately the same along the extension direction of the diversion channel to facilitate simplified processing, and this disclosure does not impose any limitations on this.

[0075] refer to FIG. 3A In some examples, at least one of the multiple diversion channels 210 extends in a straight line. This saves space, allowing for the diversion channels 210 to be arranged circumferentially around the diversion element 200 as needed. Furthermore, it simplifies the manufacturing process of the diversion element 200 and reduces manufacturing costs.

[0076] refer to FIG. 3A For example, among the multiple diversion channels 210, only one diversion channel 210 may extend in a straight line. For example, among the multiple diversion channels 210, there may be two or more, such as all diversion channels 210 extending in a straight line; this disclosure does not impose any limitation on this.

[0077] refer to FIG. 3A and combined FIG. 2 For example, the diverter 200 may be generally cylindrical in shape, and the diverter channel 210 may extend along the generatrix of the cylindrical structure. For example, in conjunction with the examples described later, when the diverter 200 includes a third annular wall 240 and the outer wall of the third annular wall 240 generally forms a frustum structure, the diverter channel 210 may extend along the generatrix of the frustum structure.

[0078] However, this disclosure is not limited thereto. For example, in other examples, the diversion channel may extend along a curve, such as a spiral, and the liquid flowing through the diversion channel may be thrown out of the diversion channel due to inertia. Of course, the diversion channel may also be designed to have other shapes or extend in other directions. It is understood that this disclosure is not limited in any way as long as the diversion channel can be used to divert liquid.

[0079] FIG. 3B for FIG. 3A A schematic diagram of the diverter from another perspective. FIG. 3C This is a schematic diagram of a flow divider of a water spray assembly provided in at least one embodiment of the present disclosure.

[0080] FIG. 3BThe flow divider shown is FIG. 3C The difference between the flow dividers shown is that, FIG. 3B The flow distribution channel of the flow divider shown is... FIG. 3C The flow distribution channels of the flow distribution components shown are different. FIG. 3B The protrusion of the flow divider shown is... FIG. 3C The protrusions on the shown flow dividers are different. This is understandable. FIG. 3C The shown diverter can also be used with FIG. 1 The main component assembly shown is different from the one shown. FIG. 1 and FIG. 2 The shown is a splitter component.

[0081] refer to FIG. 3B In some examples, along the circumference of the diverter 200, the outer contour of the protrusion 220 may be larger than the distance between two adjacent protrusions 220.

[0082] refer to FIG. 3B For example, the dimension of the outer contour of the protrusion 220 can be the curve length of the orthographic projection of the outer surface of the protrusion 220 on a plane perpendicular to the axis of the diverter 220. When the cross-sectional shape of the diverter 220 is approximately circular, the curve length can be, for example, the arc length.

[0083] refer to FIG. 3B For example, the distance between two adjacent protrusions 220 can be the curve length of the orthographic projection of the bottom wall of the diversion channel 210 on a plane perpendicular to the axis of the diversion member 220. When the cross-sectional shape of the diversion member 220 is approximately circular, the curve length can be, for example, the arc length.

[0084] refer to FIG. 3B By making the spacing between two adjacent protrusions 220 smaller, the diverter 200 can form a narrower diverting channel 210 using the wider protrusions 220, resulting in a diverting channel 210 with a relatively small cross-sectional area. Consequently, the liquid flowing out of the narrower diverting channel 210 is more easily dispersed by the airflow, and the liquid is less likely to accumulate into large droplets. The narrower diverting channel 210 also limits the liquid flow rate and helps save water. Furthermore, the narrower diverting channel 210 facilitates control of its cross-sectional area. The cross-sectional areas of multiple diverting channels 210 are easily made to be substantially the same, improving the uniformity of the diverting flow.

[0085] refer to FIG. 3C In some examples, along the circumference of the diverter 200, the size of the outer contour of the protrusion 220 may be less than or equal to the distance between two adjacent protrusions 220.

[0086] For example, FIG. 3CThe diagram schematically illustrates that, along the circumference of the diverter 200, the outer contour dimension of the protrusion 220 can be smaller than the distance between two adjacent protrusions 220. By setting a larger distance between two adjacent protrusions 220, the diverter 200 can form a wider diversion channel 210. Therefore, the wider diversion channel 210 is less prone to clogging. With a wider diversion channel 210, a higher airflow velocity can be introduced into the water spray assembly to disperse the liquid flowing out of the diversion channel 210, thereby achieving a better water spraying effect.

[0087] For example, in other examples, the size of the outer contour of the protrusion along the circumference of the splitter can be equal to the distance between two adjacent protrusions.

[0088] refer to FIG. 3B and FIG. 3C ,For example, FIG. 3B The diversion channel 210 shown can have a large depth, while FIG. 3C The diversion channel 210 shown can have a small depth. Therefore, the cross-sectional area of ​​the diversion channel 210 can be designed by combining the depth and the spacing between the protrusions 220.

[0089] refer to FIG. 3C and combined FIG. 2 For example, along the axis parallel to the splitter 200 and away from the air inlet 1011, FIG. 3C The depth of the diversion channel 210 shown can gradually decrease. For example, the bottom wall of the diversion channel 210 can be inclined, thereby pressurizing the liquid and increasing the liquid flow rate.

[0090] refer to FIG. 3C and combined FIG. 2 For example, the cross-sectional area of ​​the diversion channel 210 can gradually decrease along its extension direction and in the direction away from the air inlet 1011. This facilitates liquid acceleration by reducing the cross-sectional area of ​​the diversion channel 210. Furthermore, after the diversion component 200 is assembled with the main body 100, the larger opening area of ​​the diversion channel 210 near the guide channel 130 reduces the risk of internal blockage in the water spray assembly.

[0091] refer to FIG. 3A and combined FIG. 2 For example, in some examples, the diverter 200 further includes a snap-fit ​​flange 230 located on the side of the first portion P1 away from the second portion P2. The second annular wall 120 includes a snap-fit ​​portion 121, and the snap-fit ​​flange 230 and the snap-fit ​​portion 121 snap together, such as with an interference fit. Thus, the diverter 200 and the main body 100 can be fixed to each other with a simple snap-fit ​​structure.

[0092] refer to FIG. 3A and combined FIG. 2 In some examples, the snap-fit ​​flange 230 and the snap-fit ​​portion 121 are tightly fitted in the circumferential direction of the diverter 200. This allows for reliable fixation of the diverter 200 and the main body 100 in the circumferential direction, improving the connection stability between the diverter 200 and the main body 100. It also prevents liquid from flowing out from the connection point between the diverter 200 and the main body 100, thus improving the water spraying effect.

[0093] refer to FIG. 3A and combined FIG. 2 For example, the snap-fit ​​flange 230 and the snap-fit ​​portion 121 are substantially sealed to each other. However, this disclosure is not limited to this; for example, other sealing structures can be provided to improve the sealing effect at the connection between the snap-fit ​​flange 230 and the snap-fit ​​portion 121. For example, a sealing ring or similar structure can be added. For example, a sealant can be applied.

[0094] refer to FIG. 2 and FIG. 3A and combined FIG. 2 In some examples, the outer surface of the protrusion 220 fits tightly against the inner wall of the second annular wall 120. This allows the liquid to flow out primarily through the diversion channel 210, improving the liquid diversion effect. Furthermore, the tight fit between the protrusion 220 and the inner wall of the second annular wall 120 enhances the stability of the diversion member 200 and the second annular wall 120.

[0095] For example, a tight fit may include a clearance-free fit (e.g., a zero-clearance fit) or an interference fit, and this disclosure does not limit this.

[0096] refer to FIG. 2 and FIG. 3AIn some examples, the diverter 200 includes a third annular wall 240 that surrounds and forms a second air duct 201. The second air duct 201 communicates with the first air duct 101. The second air duct 201 includes two openings opposite each other in its extending direction, one of which is located at the end of the second air duct 201 near the air inlet 1011, and the other of which is located at the end of the second air duct 201 near the air outlet 1012. For example, one of the two openings communicates with the air inlet 1011, and the other of the two openings communicates with the air outlet 1012. Airflow flowing in from the air inlet 1011 can flow through the second air duct 201, thereby allowing the airflow in the first air duct 101 and the airflow in the second air duct 201 to jointly spray liquid outside the water spray assembly. By designing the second air duct 201, the formation of still air zones within the main body 100 can be prevented. Specifically, in calm air zones, residual liquid can accumulate, and this accumulated liquid may absorb some of the liquid flowing through the diversion channel 210, potentially affecting the outward spraying of water from the diversion channel 210. Therefore, by designing... FIG. 2 The second air duct 201 shown can prevent the formation of a still air zone and prevent the liquid remaining at the outlet of the diversion channel 210 away from the air inlet 1011 from condensing into larger water droplets, thereby improving the smoothness of water discharge of the water spray assembly.

[0097] refer to FIG. 2 and FIG. 3A For example, the snap-fit ​​flange 230 can be connected to one end of the third annular wall 240. For example, the protrusion 220 can be provided on the side surface of the third annular wall 240 away from the snap-fit ​​flange 230. For example, the surface of the third annular wall 240 can form the bottom wall of the diversion channel 210, and the side wall of the protrusion 220 can form the side wall of the diversion channel 210.

[0098] refer to FIG. 2 and FIG. 3A In some examples, on a reference plane perpendicular to the axis of the third annular wall 240, the orthographic projection of the side edge of the third annular wall 240 near the air inlet 1011 lies within the area surrounded by the orthographic projection of the side edge of the third annular wall 240 away from the air inlet 1011. For example, the edge of the third annular wall 240 refers to the edge of the outer wall of the third annular wall 240. The outer wall of the third annular wall 240 generally forms a frustum structure. This facilitates the guidance of liquid flow and makes it easy to assemble the flow divider 200 with the second annular wall 120.

[0099] refer to FIG. 3A For example, the thickness of the end of the third annular wall 240 away from the air inlet 1011 can be smaller, such as by thinning, to prevent water accumulation at the liquid outlet. Of course, this disclosure is not limited to this; for example, the wall thickness of the third annular wall can also be approximately uniform.

[0100] refer to FIG. 1 to FIG. 3A In some examples, along the extension direction of the axis of the second annular wall 120, the edge of the second annular wall 120 away from the air inlet 1011 protrudes from the edge of the diverter 200 away from the air inlet 1011. This helps to reduce the resistance encountered by the airflow after entering the first air duct 101 from the air inlet 101, thereby improving the water spraying effect of the water spray assembly.

[0101] refer to FIG. 2 and FIG. 3A In some examples, along the extension direction of the axis of the second annular wall 120, the edge of the second annular wall 120 away from the air inlet 1011 is approximately aligned with the edge of the diverter 200 away from the air inlet 1011. For example, the orthographic projection of the edge of the second annular wall 120 away from the air inlet 1011 on the axis approximately coincides with the orthographic projection of the edge of the diverter 200 away from the air inlet 1011 on the axis. Therefore, the inner wall of the second annular wall 120 can work together with the diverter channel 210 of the diverter 200 to guide the liquid, which is beneficial to improving the spraying effect of the liquid flowing out of the diverter channel 210.

[0102] refer to FIG. 2 and FIG. 3A For example, the diverter 200 can be completely located within the space surrounded by the second annular wall 120. Thus, while improving the water spraying effect, the second annular wall 120 can protect the diverter 200, preventing it from detaching during use of the water spray assembly. For example, the orthographic projection of the diverter 200 on its axis can be completely located within the orthographic projection of the second annular wall 120 on its axis.

[0103] FIG. 4 for FIG. 1 A schematic diagram of the main component of the water spray assembly shown.

[0104] refer to FIG. 2 and FIG. 4 In some examples, the end of the second annular wall 120 near the air outlet 1012 is located within the space surrounded by the first annular wall 110. By designing the structure of the first annular wall 110 and the second annular wall 120, it is beneficial to adjust the flow field distribution at the outlet of the first air duct 101, enhance the dispersion effect, and improve the water spraying effect.

[0105] refer to FIG. 2 and FIG. 4 For example, the end of the second annular wall 120 near the air inlet 1011 is located within the space surrounded by the first annular wall 110. As a result, the dimension of the second annular wall 120 in the direction of its axial extension can be shortened, which helps to reduce the resistance encountered by the airflow after entering the first air duct 101 from the air inlet 101.

[0106] refer to FIG. 2 In some examples, the axis of the first annular wall 110 is approximately coincident with the axis of the second annular wall 120. Thus, in the direction perpendicular to the axis, the distance between the surfaces of the first annular wall 110 and the second annular wall 120 facing each other is approximately equal, which simplifies the design and improves the uniformity of airflow, thus optimizing the airflow delivery effect.

[0107] refer to FIG. 2 and FIG. 3A In some examples, the axis of the third annular wall 240 is approximately coincident with the axis of the second annular wall 120. This makes it easier to assemble the diverter 200 with the main body 100 and improves the uniformity of liquid distribution by the diverter 200.

[0108] refer to FIG. 2 For example, the axes of the first annular wall 110, the second annular wall 120, and the third annular wall 240 coincide. It should be noted that... FIG. 2 The schematic diagram shows that the axes of the first annular wall 110, the second annular wall 120, and the third annular wall 240 coincide with the axis AX.

[0109] Of course, this disclosure is not limited thereto. For example, in other examples, at least two of the axes of the first annular wall, the second annular wall, and the third annular wall may not coincide, such as being parallel or intersecting, and this disclosure does not limit this.

[0110] FIG. 5 This is an exploded schematic diagram of a water spray assembly provided as an example in at least one embodiment of the present disclosure. FIG. 6 This is a schematic cross-sectional view of a water spray assembly provided in at least one embodiment of this disclosure. For example, FIG. 6 The water spray assembly shown is FIG. 5 The water spray assembly shown can be the same water spray assembly. FIG. 7 for FIG. 5 A schematic diagram of the flow divider in the water spray assembly shown.

[0111] It should be noted that, FIG. 5 to FIG. 7 The diverter 200 and main body 100 shown are different from those shown in the diagram. FIG. 1 to FIG. 4 The diversion component 200 and the main body 100 are shown in the diagram. For example, FIG. 6 The main body component 100 shown is... FIG. 2 The difference of the main body 100 shown may be that, FIG. 6 The main body 100 shown includes a flow guide bottom wall 140. For example, FIG. 7 The flow divider 200 shown is FIG. 3A The difference of the flow divider 200 shown may be that,FIG. 7 The flow divider 200 shown includes a guide portion 250 and a flow divider portion 260.

[0112] Of course, this disclosure is not limited to this; depending on the design requirements, FIG. 5 to FIG. 7 The main body 100 and the diversion component 200 shown can also be connected with FIG. 1 to FIG. 4 The main body 100 and the diverter 200 shown have many similarities and differences.

[0113] Understandable, FIG. 5 and FIG. 6 The specific structures of the first annular wall 110, the second annular wall 120, and the flow guiding channel 130 shown herein can be referred to the foregoing. FIG. 1 , FIG. 2 and FIG. 4 The relevant descriptions will not be repeated here.

[0114] refer to FIG. 5 to FIG. 7 In some examples, the diverter 200 includes a guide portion 250 located in a first portion P1 and a diverter portion 260 located in a second portion P2, the guide portion 250 being situated within the space surrounded by the second annular wall 120. A plurality of diverter channels 210 are provided on the diverter portion 260. The diverter 200 has an axis, and in an extension direction perpendicular to the axis of the diverter 200, the dimension of the guide portion 250 is smaller than the dimension of the diverter portion 260. Thus, the diverter 200 can be mounted within the main body 100 using the guide portion 250.

[0115] It should be noted that, FIG. 7 The design of the shape and arrangement of the multiple diversion channels 210 in the diversion component 200 shown can be referenced. FIG. 3A The design of the diversion channel 210 of the diversion component 200 shown can be uniformly arranged, extended along a straight line as a whole, or have the same cross-sectional area for any two diversion channels 210, etc., which will not be elaborated here.

[0116] refer to FIG. 7 ,For example, FIG. 7 The diagram schematically shows that the diversion component 200 has 10 diversion channels 210. However, this disclosure does not limit the number of diversion channels 210.

[0117] refer to FIG. 7In some examples, the diversion section 260 includes a first sub-section 261 and a second sub-section 262, with the first sub-section 261 connected between the guide section 250 and the second sub-section 262. In the extension direction perpendicular to the axis of the diversion member 200, the size of the first sub-section 261 is smaller than the size of the second sub-section 262. Thus, the diversion section 260 can generally form a stepped structure, facilitating assembly with the main body 100. Furthermore, designing the second sub-section 262 to be larger helps reduce the cross-sectional area of ​​the first air duct 101 near the air outlet 1012, thereby improving the outlet air velocity.

[0118] refer to FIG. 6 For example, the end face of the second annular wall 120 away from the air inlet 1011 includes a recess 122, which can match the outer surface of the first sub-part 261 to facilitate positioning the diversion part 260 and the main body 100 relative to each other.

[0119] refer to FIG. 7 For example, at least one of the first sub-part 261 and the second sub-part 262 can be approximately frustum-shaped. For example, setting the first sub-part 261 to a frustum-shaped structure facilitates the processing of the recess 122 that matches the first sub-part 261. For example, setting the second sub-part 262 to a frustum-shaped structure helps to reduce the cross-sectional area of ​​the first air duct 101 near the air outlet 1012, thereby helping to increase the air outlet velocity.

[0120] refer to FIG. 6 For example, the diverter 200 and the main body 100 can be fixed together with adhesive or by welding, such as ultrasonic welding. This disclosure does not limit this.

[0121] refer to FIG. 6 In some examples, the main body 100 also includes a flow guide bottom wall 140, which is circumferentially connected to one end of the second annular wall 120 facing the air inlet 1011. The cavity 02 formed by the flow guide bottom wall 140 and the second annular wall 120 communicates with the flow guide channel 130. Thus, liquid in the flow guide channel 130 can flow into the cavity 02 and into multiple branch channels 210.

[0122] refer to FIG. 6 For example, the guide portion 250 can extend into the cavity 02, and an annular flow channel 01 can be formed between the guide portion 250 and the second annular wall 120, thereby using the annular flow channel 01 to guide the liquid into multiple diversion channels 210.

[0123] refer to FIG. 6For example, the flow guide bottom wall 140 and the second annular wall 120 can be integrally formed. However, this disclosure is not limited to this; the flow guide bottom wall 140 and the second annular wall 120 can also be independent parts that can be assembled together, and this disclosure does not limit this.

[0124] refer to FIG. 6 In some examples, the outer surface of the guide wall 140 includes a convex surface. Thus, the convex surface can be used to guide the airflow and reduce the air resistance as the airflow moves from the inlet 1011 to the outlet 1012.

[0125] FIG. 8 This is an explosion diagram of a cleaning apparatus provided as an example in at least one embodiment of the present disclosure. FIG. 9 This is an exploded schematic diagram of the air guide structure and water spray assembly provided as an example in at least one embodiment of the present disclosure. FIG. 10 This is a cross-sectional schematic diagram of an air guide structure and a water spray assembly provided as an example in at least one embodiment of this disclosure. For example, FIG. 10 The air guide structure and water spray assembly shown are FIG. 9 The air guide structure and water spray assembly shown can be the same.

[0126] This disclosure provides a cleaning device, which may include a cleaning module. FIG. 8 The cleaning device is shown schematically, therefore, FIG. 8 The cleaning module is also illustrated.

[0127] refer to FIG. 8 , FIG. 9 and FIG. 10 At least one embodiment of this disclosure provides a cleaning module, which includes a water spray assembly. Since the cleaning module according to the embodiments of this disclosure includes the aforementioned water spray assembly, it also possesses corresponding beneficial technical effects, which will not be elaborated upon here.

[0128] Of course, when the cleaning device includes a cleaning module, it also has corresponding beneficial technical effects, which will not be elaborated here.

[0129] It should be noted that, FIG. 8 to FIG. 10 The cleaning module and cleaning device are shown only schematically. FIG. 1 An example of a water spray assembly is shown. However, this disclosure is not limited thereto. FIG. 8 to FIG. 10 The structures shown, excluding the water spray assembly, can also be combined with other water spray assemblies in the aforementioned examples, such as those that can be used with... FIG. 5 to FIG. 7 The water spray components shown in the diagram are combined to form other cleaning modules and cleaning devices.

[0130] refer to FIG. 8 , FIG. 9 and FIG. 10The cleaning module also includes a cleaning disc assembly 10 and an air guide structure 20. The cleaning disc assembly 10 surrounds an adsorption space, which is configured to generate negative pressure. The air guide structure 20 connects the adsorption space and the air inlet 1011. When negative pressure is generated in the adsorption space, the gas in the adsorption space, such as air, can be sent into the air inlet 1011 through the air guide structure 20. Thus, the airflow generated by the negative pressure can be used to spray the liquid in the water spray assembly outward, eliminating the need for additional parts such as air supply components, which is beneficial for the slimming of the cleaning module and can also reduce costs.

[0131] refer to FIG. 8 , FIG. 9 and FIG. 10 For example, the air guide structure 20 may include an air guide channel 21, and the air inlet 1011 of the water spray assembly may be connected to the air guide channel 21 to receive the airflow delivered to the water spray assembly by the air guide channel 21. For example, the air inlet of the air guide structure 20 may be designed to be relatively large, thereby facilitating the formation of an adsorption space. After the airflow entering the interior of the air guide structure 20 flows into the air guide channel 21, the airflow velocity is increased because the cross-sectional area of ​​the air guide channel 21 can be designed to be relatively small. This allows the air guide structure 20 to deliver high-speed airflow to the air inlet 1011 of the water spray assembly, optimizing the water spraying effect of the water spray assembly.

[0132] refer to FIG. 8 The cleaning device also includes an adsorption element 1000, which is configured to provide negative pressure to the adsorption space. Thus, the adsorption element 1000 can draw in gas, such as air, from the adsorption space, thereby using the gas in the adsorption space to spray liquid from the water spray assembly outwards, while simultaneously allowing the cleaning disc assembly 10 to be stably adsorbed onto the surface to be cleaned.

[0133] refer to FIG. 8 For example, the adsorption element 1000 may include a fan.

[0134] Of course, this disclosure is not limited to this. For example, in the use of FIG. 1 or FIG. 5 When using the water spray assembly shown, airflow can also be delivered into the air inlet 1011 by setting other air supply components, and this disclosure does not limit this.

[0135] FIG. 8 The diagram schematically illustrates a cleaning device comprising two integrally circular cleaning disc assemblies 10. However, this disclosure does not limit the scope of the invention, such as the structure, shape, or number of the cleaning disc assemblies 10.

[0136] For example, a cleaning device may include only one cleaning disc assembly, or it may include two or more cleaning disc assemblies.

[0137] For example, in the case where the cleaning device includes two or more cleaning disc assemblies, the shapes of the multiple cleaning disc assemblies can be the same or different. Taking a cleaning device including two cleaning disc assemblies as an example, the cleaning device can be as follows: FIG. 8 The diagram shows two circular cleaning tray assemblies, or it may include one square and the other circular cleaning tray assembly.

[0138] refer to FIG. 8 and FIG. 9 For example, the air guiding structure 20 may include multiple air guiding channels 21, and the cleaning module may include multiple water spraying components, with each water spraying component corresponding to one of the multiple air guiding channels 21. This allows water to be sprayed onto multiple locations, thereby improving cleaning efficiency.

[0139] refer to FIG. 8 and FIG. 9 For example, two water spray components can be provided. In the case where the cleaning module is applied in the cleaning device, the two water spray components can be provided on both sides in the width direction of the cleaning device.

[0140] refer to FIG. 8 For example, the cleaning device may also include a water tank 2000, a water pump 3000 and a water pipe 4000. The water pipe 4000 may be connected between the water tank 2000 and the flow channel 130. The water pump 3000 may pump the liquid in the water tank 2000 into the flow channel 130 through the water pipe 4000, thereby diverting the liquid through the diversion channel 210 and spraying it outward under the action of airflow.

[0141] refer to FIG. 8 For example, the cleaning device may also include a housing 5000, a mounting component 6000, and a drive component 7000. The adsorption component 1000, water pump 3000, water pipe 4000, air guide structure 20, drive component 7000, and mounting component 6000 may be mounted on the housing 5000, and the water tank 2000 may be mounted on the mounting component 6000. For example, the drive component 7000 may include a motor.

[0142] refer to FIG. 8 For example, the cleaning tray assembly 10 can be connected to the side of the housing 5000 away from the air guide structure 20. For example, a wiping element, such as a rag, can be fitted over the cleaning tray assembly 10.

[0143] For example, cleaning devices can include window cleaning robots.

[0144] For example, cleaning devices may include robotic vacuum cleaners, robotic floor scrubbers, etc., and this disclosure does not limit them. The following points need to be noted:

[0145] (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure, and other structures can be referred to the general design.

[0146] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure may be combined with each other.
