Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device and a cleaning system. Background Technology

[0002] Cleaning devices include robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning devices often use rollers to clean various stains such as dust, hair, and oil from the surface to be cleaned.

[0003] Currently, in the cleaning process, the cleaning device typically first sprays water to wet the roller, allowing the water to adhere to the roller surface before it immediately contacts the surface to be cleaned, thus achieving cleaning. However, due to the excessive amount of water absorbed by the roller surface, a large amount of water stains are easily left on the surface to be cleaned during the cleaning process, greatly affecting the cleaning effect of the device. Utility Model Content

[0004] The main purpose of this application is to provide a cleaning device and cleaning system to solve the problem that the cleaning device in the prior art has excessive water adsorption on the surface of the roller, which easily leaves water stains on the surface to be cleaned, resulting in poor cleaning effect.

[0005] According to one aspect of this application, a cleaning apparatus is provided, comprising:

[0006] body;

[0007] A cleaning assembly is rotatably disposed at the bottom of the machine body. The cleaning assembly includes a mounting bracket and a cleaning component. The mounting bracket is disposed on the machine body, and the cleaning component is rotatably connected to the mounting bracket.

[0008] A spray assembly, which is disposed on the machine body or the mounting frame, is used to spray liquid onto the cleaning component to wet the cleaning component;

[0009] A scraping assembly is disposed on the body or the mounting bracket, and at least a portion of the scraping assembly abuts against the outer surface of the cleaning component to scrape off a portion of the liquid on the cleaning component when the cleaning component rotates;

[0010] The cleaning device has a cleaning mode. When the cleaning device is in the cleaning mode, the cleaning component rotates in a first direction and passes through the spray assembly to spray liquid and through the scraping assembly to scrape liquid before contacting the surface to be cleaned to clean the surface.

[0011] Furthermore, the cleaning component has a dividing surface parallel to the height direction of the body, the dividing surface separating the cleaning component into a first side and a second side, the first side being located on the side of the dividing surface closer to the inner side of the body, and the second side being located on the side of the dividing surface away from the inner side of the body, the spray assembly being disposed on the first side, and the scraping assembly being disposed on the second side; and / or,

[0012] Along the height direction of the machine body, the distance from the bottom of the scraping assembly to the surface to be cleaned is greater than or equal to the distance from the rotation center of the cleaning component to the surface to be cleaned.

[0013] Furthermore, the scraping assembly is disposed on the mounting bracket, the scraping assembly includes a scraper, the scraper extends in a direction close to the cleaning component, and the scraper is inclined in a direction away from the surface to be cleaned, and the first end of the scraper abuts against the outer surface of the cleaning component.

[0014] Furthermore, a water inlet channel is provided on the scraper blade, and a wastewater tank is also provided on the machine body. The wastewater tank is connected to the second end of the scraper blade and communicates with the water inlet channel.

[0015] Furthermore, the wastewater tank includes a tank body and a wastewater trough. The tank body is located on the rear side of the machine body in the forward direction, and the wastewater trough is located on the side of the tank body near the inner side of the machine body and at the bottom of the scraper.

[0016] The second end of the scraper is provided with a guide section, which extends toward the direction of the sewage tank.

[0017] Furthermore, there is a gap between the guide section and the cleaning component, and an extension section is provided on the side of the sewage tank away from the tank body. The extension section extends in a direction away from the surface to be cleaned and is inserted into the gap.

[0018] Furthermore, the inclination angle θ of the scraper blade satisfies the following relationship: 15°≤θ≤60°.

[0019] Furthermore, the scraper is rotatably connected to the mounting bracket via a connecting rod and abuts against the outer surface of the cleaning component. A torsion spring is provided on the connecting rod, with one end of the torsion spring abutting against the mounting bracket and the other end of the torsion spring abutting against the scraper.

[0020] Furthermore, the cleaning device also includes a movable wheel, which is rotatably disposed at the bottom of the body. When the cleaning device is in the cleaning mode, the rotation direction of the movable wheel is opposite to the rotation direction of the cleaning component.

[0021] On the other hand, this application also provides a cleaning system, which includes the cleaning device described above.

[0022] When the cleaning device of this application is in cleaning mode, the cleaning component rotates along a first direction at the bottom of the device body to clean stains and other contaminants on the surface to be cleaned. During this process, the cleaning component first passes through a spray assembly, which sprays liquid onto the surface of the cleaning component to wet it, facilitating the dissolution and absorption of stains on the surface to be cleaned. Subsequently, the cleaning component continues to rotate along the first direction to pass through a scraping assembly, which closely adheres to the outer surface of the cleaning component and promptly scrapes away excess liquid, effectively controlling the liquid content on the surface of the cleaning component and preventing water stains from remaining on the surface to be cleaned due to excessive water on the surface. Then, the cleaning component continues to rotate along the first direction to clean the surface to be cleaned. The entire cleaning process significantly reduces water residue and improves the cleaning effect of the cleaning device. Meanwhile, after the cleaning component cleans the surface to be cleaned, it continues to rotate in the first direction and passes through the spray assembly and the scraping assembly again. During this process, the spray assembly first sprays liquid onto the surface of the cleaning component to remove the attached stains, while the scraping assembly promptly scrapes away the wastewater on the cleaning component, ultimately achieving self-cleaning of the cleaning component and facilitating the normal progress of subsequent cleaning work.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0037] As mentioned in the background section, existing cleaning devices typically wet the roller with water before cleaning, allowing the roller surface to immediately contact the surface to be cleaned. However, due to the excessive water adsorbed on the roller surface, a large amount of water stains are easily left on the surface during cleaning, significantly affecting the cleaning effect. To address this, the inventors of this application have designed a novel cleaning device that solves the problem of excessive water adsorption on the roller surface in existing cleaning devices, leading to water stains and poor cleaning performance. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.

[0038] It should be noted that "first direction" in this application refers to the attached... Figure 2 The direction indicated by the letter X; "second direction" refers to the attached... Figure 2 The direction indicated by the letter Y.

[0039] See Figures 1 to 3 As shown, according to an embodiment of this application, a cleaning device is provided, which includes a body 10, a cleaning component 20, a spraying component 30, and a scraping component 40.

[0040] Specifically, the cleaning component 20 is rotatably disposed at the bottom of the body 10. The cleaning component 20 includes a mounting frame 21 and a cleaning element 22. The mounting frame 21 is disposed on the body 10, and the cleaning element 22 is rotatably connected to the mounting frame 21. The spraying component 30 is disposed on the body 10 or the mounting frame 21, and the spraying component 30 is used to spray liquid onto the cleaning element 22 to wet the cleaning element 22. The scraping component 40 is disposed on the body 10 or the mounting frame 21, and at least a portion of the scraping component 40 abuts against the outer surface of the cleaning element 22 to scrape off some of the liquid on the cleaning element 22 when the cleaning element 22 rotates. The cleaning device has a cleaning mode. When the cleaning device is in the cleaning mode, the cleaning element 22 rotates in a first direction and sequentially passes through the spraying component 30 to spray liquid and through the scraping component 40 to scrape off liquid before contacting the surface to be cleaned 50 to clean the surface to be cleaned. For example, the liquid in this embodiment can be clean water, cleaning liquid, or a mixture of clean water and cleaning liquid.

[0041] When the cleaning device in this embodiment is in the cleaning mode, the cleaning member 22 rotates in a first direction at the bottom of the body 10 to clean stains and the like on the surface to be cleaned 50. In this process, the cleaning member 22 first passes through the spray assembly 30, and the spray assembly 30 sprays liquid onto the surface of the cleaning member 22 to keep the cleaning member 22 in a wet state, which facilitates the cleaning member 22 to dissolve and adsorb stains on the surface to be cleaned. Then, the cleaning member 22 continues to rotate along the first direction to pass through the scraping assembly 40. The scraping assembly 40 is in close contact with the outer surface of the cleaning member 22 and scrapes off excess liquid in time, thereby effectively controlling the liquid content on the surface of the cleaning member 22 and avoiding residual water stains on the surface to be cleaned 50 during cleaning caused by excessive water on the surface of the cleaning member 22. Then, the cleaning member 22 continues to rotate in the first direction to clean the surface to be cleaned 50. The entire cleaning process greatly reduces the residual amount of water stains and improves the cleaning effect of the cleaning device. Meanwhile, after the cleaning member 22 cleans the surface to be cleaned 50, the cleaning member 22 continues to rotate along the first direction and passes through the spray assembly 30 and the scraping assembly 40 again. In this process, the spray assembly 30 first sprays liquid onto the surface of the cleaning member 22 to remove adhered stains, and the scraping assembly 40 scrapes off the sewage on the cleaning member 22 in time, finally realizing the self-cleaning of the cleaning member 22 and facilitating the normal progress of subsequent cleaning work.

[0042] Compared with the prior art, in the cleaning device of the present embodiment, after the cleaning member 22 is pre-wetted by the spray assembly 30, the scraping assembly 40 is used to scrape off the excess liquid on the cleaning member 22, so that the cleaning member 22 contacts the surface to be cleaned 50 in a moderately wetted state without excess liquid, reducing the transmission of moisture to the surface to be cleaned 50 from the source, reducing the residual amount of water stains on the surface to be cleaned 50, and effectively improving the cleaning efficiency of the cleaning device.

[0043] Exemplarily, the surface to be cleaned 50 in the present application includes hard floors (such as ceramic tiles, wood floors), soft floors (such as carpets), tabletops and the like.

[0044] Further, referring to Figure 2 , the cleaning member 22 in this embodiment has a median plane 201 parallel to the height direction of the body 10. The median plane 201 divides the cleaning member 22 into a first side 202 and a second side 203. The first side 202 is located on a side of the median plane 201 close to the inner side of the body 10, and the second side 203 is located on a side of the median plane 201 away from the inner side of the body 10. The spray assembly 30 is disposed on the first side 202, and the scraping assembly 40 is disposed on the second side 203. It should be noted that the "inner side of the body 10" in this embodiment refers to the side indicated Figure 2 by the word "inner" in the accompanying drawing; the "outer side of the body 10" refers to the side indicated Figure 2 by the word "outer" in the accompanying drawing.

[0045] Specifically, in this embodiment, the spray assembly 30 is located on the first side 202, and the scraping assembly 40 is located on the second side 203. This allows the cleaning component 22 to complete the "spraying and wetting - scraping and controlling" process in an orderly manner during rotation. Furthermore, the spray assembly 30, located on the first side 202 near the inner side of the body 10, prevents excessive liquid spraying onto the outer side of the body 10, ensuring precise application of the cleaning liquid to the cleaning component 22 and reducing waste. The scraping assembly 40, located on the second side 203 away from the inner side of the body 10, can promptly treat the liquid on the surface of the cleaning component 22 as it rotates in the first direction, preventing liquid from flowing back into the body 10 and causing contamination. Simultaneously, the spraying and scraping processes in this embodiment are spatially independent and do not interfere with each other, effectively improving the control precision of the liquid volume on the surface of the cleaning component 22 and preventing water stains from remaining on the surface 50 during cleaning due to excessive liquid residue. This, in turn, improves the overall cleaning efficiency and effect of the cleaning device.

[0046] Further, see Figure 2 As shown, along the height direction of the body 10, the distance from the bottom of the scraping assembly 40 to the surface 50 to be cleaned in this embodiment is greater than or equal to the rotation center of the cleaning component 22. Figure 2 The distance from point O (as shown in the diagram) to the surface 50 to be cleaned is thus ensured. This ensures that during the rotation of the cleaning component 22, the scraping assembly 40 can contact the outer surface of the cleaning component 22 at a suitable angle and pressure, effectively scraping away excess liquid. Simultaneously, the precise height setting ensures that the scraping assembly 40 does not contact the surface 50 to be cleaned, preventing secondary contamination of the cleaned area by residual wastewater during the scraping process. This also ensures that the scraping assembly 40 can control the liquid flow from the cleaning component 22, allowing the cleaning component 22 to contact the surface 50 in an ideal wetted state, avoiding water stains and improving cleaning effectiveness. Furthermore, it ensures that the scraping assembly 40 maintains a distance from the surface 50 to be cleaned throughout the cleaning process, avoiding wear caused by direct contact.

[0047] Further, see Figures 2 to 3 As shown, the scraping assembly 40 in this embodiment is disposed on the mounting bracket 21. The scraping assembly 40 includes a scraper 41, which extends in a direction close to the cleaning component 22 and is inclined in a direction away from the surface to be cleaned 50. The first end of the scraper 41 abuts against the outer surface of the cleaning component 22.

[0048] Specifically, in this embodiment, the scraping assembly 40 is integrated into the mounting bracket 21, which reduces the complex structure connecting it to the body 10, making the overall layout more compact, reducing the space occupied by the cleaning device, and facilitating installation, disassembly, and maintenance. Meanwhile, since the scraper 41 in this embodiment extends towards the cleaning component 22, when the cleaning component 22 rotates in the first direction, the scraper 41 can better conform to the outer surface of the cleaning component 22, thereby scraping away excess liquid and avoiding problems such as liquid splashing and incomplete scraping caused by vertical or reverse contact. Furthermore, since the first end of the scraper 41 in this embodiment abuts against the outer surface of the cleaning component 22, the amount of liquid residue on the surface of the cleaning component 22 can be effectively controlled, ensuring that the cleaning component 22 carries an appropriate amount of liquid when contacting the surface to be cleaned 50, effectively dissolving stains while preventing water residue, thus improving the cleaning efficiency of the cleaning device. In addition, the inclined design of the scraper 41 can guide the scraped liquid to flow in a specific direction, preventing liquid accumulation inside the cleaning component 22 or the body 10, thereby reducing the risk of component corrosion and extending the service life of the cleaning device.

[0049] In other words, during the rotation of the cleaning component 22 in the first direction, the first end of the scraper 41 can contact the outer surface of the cleaning component 22, thereby scraping off the excess liquid on the cleaning component 22, so that the scraped liquid flows along the scraper 41, thereby preventing water stains from remaining on the surface 50 to be cleaned due to excessive water in the cleaning component 22.

[0050] Further, see Figure 3 and Figure 5 As shown, in this embodiment, a water inlet channel 42 is provided on the scraper 41, and a sewage tank 60 is also provided on the body 10. The sewage tank 60 is connected to the second end of the scraper 41 and communicates with the water inlet channel 42.

[0051] Specifically, in this embodiment, the water inlet channel 42 provides a dedicated flow path for the liquid scraped off by the scraper 41. This allows excess liquid on the surface of the cleaning component 22, as well as wastewater scraped off during self-cleaning, to flow directly and efficiently into the wastewater tank 60 through the water inlet channel 42. This prevents liquid from flowing and accumulating randomly inside the cleaning component 22 or the body 10, reducing the risk of component corrosion and short circuits caused by liquid residue and improving the durability of the cleaning device. The wastewater tank 60 enables centralized collection and management of wastewater. Users only need to clean the wastewater tank 60 periodically to dispose of wastewater, eliminating the need for frequent cleaning of components such as the cleaning component 22.

[0052] In other words, when the cleaning component 22 rotates in the first direction, the scraper 41 can scrape off the liquid on the cleaning component 22. The scraped liquid enters the sewage tank 60 through the water inlet channel 42, thereby achieving the scraping and collection of the liquid.

[0053] Further, see Figure 3 and Figure 6 As shown, the wastewater tank 60 in this embodiment includes a tank body 61 and a wastewater trough 62. The tank body 61 is located on the rear side of the machine body 10 in the forward direction, and the wastewater trough 62 is located on the side of the tank body 61 near the inner side of the machine body 10 and at the bottom of the scraper 41. The second end of the scraper 41 is provided with a guide section 43, which extends towards the wastewater trough 62. It should be noted that the "forward direction of the machine body 10" in this application refers to the normal driving direction of the machine body 10 when the cleaning device is in cleaning mode and performing cleaning operations; "rear side of the forward direction of the machine body 10" refers to the side of the machine body 10 opposite to the front end of the forward direction (i.e., the side away from the front end of the forward direction) based on the normal forward direction of the machine body 10 when performing cleaning operations in cleaning mode.

[0054] Specifically, in this embodiment, by placing the wastewater tank 62 on the inner side of the housing 61 near the body 10 and at the bottom of the scraper 41, the liquid scraped by the scraper 41 flows into the wastewater tank 62 under gravity, shortening the liquid flow path and reducing the accumulation of residual liquid inside the body 10. Simultaneously, since the wastewater tank 62 is located on the inner side of the housing 61 near the body 10, this fully utilizes the internal space of the body 10, making the overall structure of the cleaning device more compact and rational. Furthermore, in this embodiment, the guide section 43 extends towards the wastewater tank 62, further optimizing the liquid guiding effect, thereby accurately guiding the liquid to the wastewater tank 62, avoiding splashing, side leakage, and improving liquid recovery efficiency.

[0055] That is to say, when the cleaning component 22 rotates in the first direction, the scraper 41 can scrape off the liquid on the cleaning component 22. The scraped liquid flows to the sewage tank 62 through the water inlet channel 42. During this process, the liquid can flow directly into the sewage tank 62 through the water inlet channel 42, or it can flow into the guide section 43 after passing through the water inlet channel 42 and then into the sewage tank 62.

[0056] Further, see Figure 5 As shown, in this embodiment, the water inlet channel 42 is provided with at least one reinforcing rib 45, which divides the water inlet channel 42 into at least two water outlets. Exemplarily, the reinforcing rib 45 in this embodiment can be one or more ribs.

[0057] Specifically, the reinforcing rib 45 strengthens the structure of the scraper 41, preventing damage to the scraper 41 from external forces due to the water inlet channel 42. Simultaneously, the reinforcing rib 45 divides the water inlet channel 42 into multiple outlet holes, allowing the liquid scraped by the scraper 41 to flow into the wastewater tank 62 simultaneously through these outlet holes.

[0058] Furthermore, in this embodiment, a suction assembly is provided between the sewage tank 62 and the housing 61. When the sewage scraped off by the scraper 41 enters the sewage tank 62, the sewage in the sewage tank 62 enters the housing 61 under the suction force of the suction assembly. It should be noted that in this embodiment, the housing 61, the sewage tank 62, and the suction assembly can be separately configured or integrally formed.

[0059] Further, see Figure 6 As shown, in this embodiment, a mesh 64 is provided inside the sewage tank 62. The mesh 64 can intercept solid impurities (such as hair, dust clumps, debris, etc.) scraped into the sewage tank 62 during the cleaning process, preventing solid impurities from entering the drainage pipe or circulation system of the sewage tank 60, preventing pipe blockage caused by the accumulation of debris, and ensuring smooth sewage discharge.

[0060] Further, see Figure 3 As shown, in this embodiment, there is a gap 44 between the guide section 43 and the cleaning component 22. The sewage tank 62 is provided with an extension section 63 on the side away from the tank 61. The extension section 63 extends in a direction away from the surface to be cleaned 50 and is inserted into the gap 44.

[0061] Specifically, the gap 44 prevents direct contact between the guide section 43 and the cleaning component 22, preventing wear caused by friction during the rotation of the cleaning component 22 and extending the service life of each component. Simultaneously, the gap 44 provides a buffer flow space for the scraped liquid, ensuring smooth flow. The extension section 63 of the wastewater tank 62 is inserted into the gap 44, forming a tight "liquid guide channel." This accurately guides the liquid discharged via the scraper 41 directly into the wastewater tank 62, preventing side leakage and splashing during flow, and avoiding contamination of other internal components of the machine body 10 or secondary pollution. Furthermore, the cooperation between the extension section 63 and the gap 44 enhances the structural stability between the wastewater tank 62 and the scraping assembly 40, making the entire wastewater recycling process more reliable.

[0062] Furthermore, in this embodiment, the tilt angle θ of the scraper 41 (e.g.) Figure 3 As shown, the following relationship is satisfied: 15°≤θ≤60°. For example, θ can be set to 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.

[0063] Specifically, when the tilt angle θ of the scraper 41 in this embodiment satisfies the above-mentioned relationship, on the one hand, the scraper 41 can closely adhere to the outer surface of the cleaning part 22 at a suitable cutting angle, ensuring that excess liquid is fully scraped off, and on the other hand, it can avoid liquid splashing due to an excessively large angle or incomplete scraping due to an excessively small angle, ensuring that the cleaning part 22 contacts the surface 50 to be cleaned in an ideal wet state. On the other hand, it can allow the scraped liquid to flow smoothly along the surface of the scraper 41 into the wastewater tank 60 under the action of gravity, avoiding liquid residue or backflow that contaminates the inside of the machine body 10. However, when θ is less than 15°, the tilt angle of the scraper 41 is too small, causing the scraper 41 to tend to be parallel to the surface of the cleaning part 22, resulting in insufficient contact pressure. As a result, it is difficult to effectively scrape off the liquid attached to the surface of the cleaning part 22, causing liquid residue, affecting the cleaning effect, and even causing the cleaning part 22 to splash or be secondary contaminated in subsequent operations due to excessive liquid. Meanwhile, if the tilt angle is too small, the liquid will not have enough power to flow along the scraper 41 to the wastewater tank 60. The liquid is likely to stagnate on the surface of the scraper 41 or flow back to the cleaning component 22, which not only reduces the wastewater recycling efficiency but may also contaminate the inside of the machine body 10. When θ is greater than 60°, the tilt angle of the scraper 41 is too large. When the cleaning component 22 rotates, the scraper 41 will cut into the surface of the cleaning component 22 at a steep angle and scrape off the liquid at high speed. At this time, the liquid will be impacted and splash, causing the liquid to deviate from the predetermined flow path and contaminate the external environment of the machine body 10 or splash into other components.

[0064] Further, see Figure 4 and Figure 7 As shown, in this embodiment, the scraper 41 is rotatably connected to the mounting bracket 21 via a connecting rod 70 and abuts against the outer surface of the cleaning component 22. A torsion spring 80 is provided on the connecting rod 70, with one end of the torsion spring 80 abutting against the mounting bracket 21 and the other end abutting against the scraper 41. Exemplarily, in this embodiment, the cleaning component 22 includes a roller, with a mop cloth disposed on the outer periphery of the roller, and the scraper 41 abutting against the roller mop cloth.

[0065] Specifically, in this embodiment, the mounting bracket 21 serves as a carrier connecting the machine body 10 and the cleaning component 22, providing stable rotational support for the cleaning component 22 and ensuring stable operation of the cleaning process. In this embodiment, the scraper 41 is rotatably connected to the mounting bracket 21 via the connecting rod 70. Combined with the elastic action of the torsion spring 80, the scraper 41 can adapt to subtle changes on the surface of the cleaning component 22, maintaining a tight contact at all times. This effectively removes excess liquid and stains from the surface of the cleaning component 22, avoiding uneven contact or excessive wear caused by rigid connections. Simultaneously, the torsion spring 80 provides a certain degree of elastic cushioning, absorbing vibration and impact during the rotation of the cleaning component 22, reducing hard friction between the scraper 41 and the cleaning component 22, and extending their service life.

[0066] Furthermore, in an embodiment not shown in this application, the cleaning component 20 also includes a motor, the output end of which passes through the drum to drive the drum to rotate about its own axis.

[0067] Further, see Figure 2 As shown, the cleaning device in this embodiment also includes a movable wheel 90, which is rotatably disposed at the bottom of the body 10. When the cleaning device is in cleaning mode, the rotation direction of the movable wheel 90 is opposite to the rotation direction of the cleaning component 22. That is to say, the movable wheel 90 rotates in a second direction opposite to the first direction.

[0068] Specifically, when the cleaning device in this embodiment is in operation, the movable wheels 90 located at the bottom of the body 10 can move the entire cleaning device within space to perform cleaning operations. When the cleaning device is in cleaning mode, the rotation direction of the movable wheels 90 is opposite to the rotation direction of the cleaning component 22. This allows the movable wheels 90 and the cleaning component 22 to generate relative motion during their opposite rotation, thereby enhancing the cleaning force of the cleaning component 22 and further ensuring its cleaning effect. Simultaneously, the opposite rotation counteracts the reaction force generated by the rotation of the cleaning component 22 on the body 10, preventing positional drift of the cleaning device during operation and ensuring precise cleaning.

[0069] Further, see Figure 7 As shown, in this embodiment, the mounting frame 21 is provided with a water supply channel 211 and multiple spray nozzles 212. The water supply channel 211 is laid on the mounting frame 21 along the extension direction of the cleaning component 22. The spray nozzles 212 are located on the side of the mounting frame 21 near the cleaning component 22 and communicate with the water supply channel 211. The spray assembly 30 includes a spray plate 31, which covers the water supply channel 211 and is used to introduce liquid into the water supply channel 211. Specifically, in this embodiment, after liquid is introduced into the water supply channel 211 through the spray plate 31, the liquid can be sprayed onto the cleaning component 22 through the spray nozzles 212, so that the cleaning component 22 is wetted to better clean the surface 50 to be cleaned, thereby improving the cleaning effect and cleaning efficiency.

[0070] Specifically, see Figures 7 to 8 As shown, in this embodiment, the spray plate 31 is provided with a pipe joint 311, and the spray assembly 30 also includes a water pipe 32, a water pump 33, and a clean water tank 34. The two opposite ends of the water pipe 32 are respectively connected to the clean water tank 34 and the pipe joint 311, and the water pump 33 is disposed on the water pipe 32. Of course, in other embodiments of this application, the water pump 33 may also be disposed inside the clean water tank 34.

[0071] Specifically, the liquid in the clean water tank 34 flows out of the clean water tank 34 under the pumping action of the water pump 33, and flows through the water pipe 32 to the spray plate 31, and then from the spray plate 31 to the water supply channel 211 to achieve liquid supply. When liquid is introduced into the water supply channel 211, the liquid can be sprayed onto the cleaning component 22 through the spray nozzle 212 to wet the cleaning component 22.

[0072] On the other hand, embodiments of this application also provide a cleaning system that includes the aforementioned cleaning device, and therefore, the cleaning system encompasses all the technical effects of the aforementioned cleaning device. Since the technical effects of the cleaning device have already been described in detail above, they will not be repeated here.

[0073] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0074] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0075] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
