[0038] Reference Figure 1In the embodiment of the utility model, a cleaning device is provided, including a main body 100, a cleaning component 200 and a sewage discharge structure 300. The main body 100 has an installation cavity 110 inside, and part of the cleaning component 200 is accommodated in the installation cavity 110, and a part of the cleaning component 200 is exposed from the installation cavity 110, so that the cleaning component 200 can contact with the working surface and clean the working surface. The working surface is not limited to the ground, the top surface of the platform and other surfaces with cleaning requirements; the cleaning component 200 is rotatably connected to the main body 100. During the rotation of the cleaning component 200 relative to the main body 100, its outer peripheral surface and the working surface rub against each other, producing the effect of wiping and cleaning the working surface. The cleaning component 200 is installed on the main body 100 through rotatable components such as a rotating shaft and a bearing, and both ends of the cleaning component 200 in the axial direction are supported by the main body 100. The rotation of the cleaning component 200 can be directly driven by a motor that can output rotational power, or it can be indirectly driven by the motor to the cleaning component 200 through the cooperation of a transmission structure such as a gear set and a connecting rod with the motor. To facilitate the cleaning of the working surface by the cleaning component 200, an opening 120 for exposing the cleaning component 200 is provided at the bottom of the main body 100, and the opening 120 is connected to the installation cavity 110. When the cleaning device is in working state, the cleaning component 200 rotates continuously and keeps the bottom of the cleaning component 200 in stable contact with the working surface to ensure the cleaning effect.

[0039] The sewage discharge structure 300 is connected to the main body 100 and is located at one side of the opening 120. The sewage discharge structure 300 includes a scraper 310 and a sewage storage box 320. One end of the scraper 310 abuts against the outer peripheral surface of the cleaning component 200. During the rotation of the cleaning component 200, the scraper 310 and the outer peripheral surface of the cleaning component 200 generate relative movement. The scraper 310 can scrape off impurities and dirt on the surface of the cleaning component 200, and squeeze the cleaning component 200 to make the cleaning component 200 discharge sewage. In addition, at least part of the scraper 310 defines a sewage inlet 130. The inner cavity of the sewage storage box 320 is connected to the installation cavity 110 through the sewage inlet 130. The dirt and sewage discharged from the surface of the cleaning component 200 can enter the sewage storage box 320 through the sewage inlet 130 and be temporarily stored by the sewage storage box 320. The main body 100 is also provided with a water injection hole 140, which is connected to the installation cavity 110. The water injection hole 140 can lead cleaning liquid to the cleaning component 200. The cleaning liquid is not limited to clean water, a solution containing a cleaning agent, etc. The cleaning liquid flowing to the outer surface of the cleaning component 200 can clean the outer peripheral surface of the cleaning component 200 to remove dirt on the outer surface of the cleaning component 200, so that the cleaning component 200 remains in a clean state, and can continuously clean the working surface to avoid the situation where the cleaning component 200 contaminates the working surface for the second time.

[0040] The cleaning equipment has the working state of cleaning the working surface, such as Figure 1As shown, when the cleaning device is in working state, the main body 100 moves along the first direction, and the cleaning component 200 rotates along the second direction. The cleaning component 200 moves synchronously with the movement of the main body 100, so that the cleaning component 200 can clean the working surfaces at different positions; in addition, along the second direction, the sewage inlet 130 is located at the front side of the water injection hole 140, and the scraper 310 is located at the front side of the sewage inlet 130, and along the first direction, the sewage inlet 130 is located at the rear side of the water injection hole.

[0041] On the one hand, with a certain area A on the outer peripheral surface of the cleaning component 200 as a reference, when the cleaning component 200 rotates in the second direction, the area A passes through the water injection hole 140, the sewage inlet 130 and the scraping member 310 in sequence. When the cleaning liquid introduced from the water injection hole 140 flows to the area A, the cleaning liquid cleans the area A and generates sewage. As the cleaning component 200 continues to rotate, when the area A moves to the scraping member 310, the sewage and dirt in the area A are discharged due to the squeezing and scraping action of the scraping member 310. The inlet 130 is defined by the scraper 310 and the inner wall of the main body 100, and the inlet 130 is located behind the scraper 310 in the rotation direction of the cleaning component 200. The sewage and dirt scraped by the scraper 310 can be directly discharged into the dirt storage box 320 through the inlet 130. After the A area passes through the scraper 310, the sewage and dirt on its surface have been discharged and will no longer pollute the working surface. The cleaning equipment has a good cleaning effect on the working surface, and there is no need to set up an additional structure for scraping off the sewage on the working surface, which is more convenient to use. On the other hand, if Figure 1 As shown, the cleaning component 200 rotates along the second direction while following the main body 100 to move along the first direction. The portion of the cleaning component 200 exposed from the opening 120 is used to clean the working surface, and this portion is defined as a cleaning area. The cleaning area has a tendency to rotate leftward and simultaneously follows the main body 100 to move leftward. Therefore, the moving speed of the cleaning area relative to the working surface is the sum of the linear speed of the cleaning area and the moving speed of the main body 100. The degree of friction between the cleaning area and the working surface can be increased, so that the cleaning of the working surface can be more thorough.

[0042] It should be noted that the first direction is the forward direction of the cleaning equipment. When the cleaning equipment moves forward, the main body 100 moves in the direction away from the sewage discharge structure 300; the second direction is the rotation direction of the cleaning component 200 when the cleaning equipment moves forward, and the linear speed of the top position of the cleaning component 200 is away from the first direction, and the linear speed of the cleaning area is always toward the first direction, that is, when the cleaning component 200 rotates in the second direction, the top position of the cleaning component 200 passes through the sewage discharge structure 300 and the cleaning area in sequence.

[0043] In addition, the sewage inlet 130 can be defined by the scraper 310 alone, that is, the scraper 310 has the sewage inlet 130, the scraper 310 is connected to one side of the sewage storage box 320, and the inner cavity of the sewage storage box 320 is connected to the sewage inlet 130; or the sewage inlet 130 is defined by the scraper 310 and the inner wall of the main body 100, which can simplify the structure of the scraper 310; or the sewage inlet 130 is defined by the scraper 310 and the inner wall of the sewage storage box 320, and the sewage can directly enter the interior of the sewage storage box 320 along the inner wall of the sewage storage box 320, so that the sewage can be more conveniently collected in the sewage storage box 320. The cleaning component 200 includes a roller brush, a roller-shaped rag, a crawler rag, etc. for cleaning and wiping the working surface. Taking the cleaning component 200 including the roller 210 as an example, the roller 210 is similar to a cylindrical structure, and the outer surface of the roller 210 is provided with a liquid absorption layer, which can contact with the working surface to clean and wipe the working surface and absorb the sewage on the working surface. The cleaning force on the working surface is high, and the roller 210 occupies a small space in the installation cavity 110, which is beneficial to the position and layout of the roller 210 in the installation cavity 110, and the miniaturized design of the cleaning equipment.

[0044] like Figure 2 As shown, a driving module 400 is provided in the cleaning device, the driving module 400 is connected to the main body 100, and can drive the main body 100 to move along the first direction, so that the cleaning device has a walking function; the driving module 400 includes a rotatable roller, the roller is in contact with the working surface, and the main body 100 is driven to move along the first direction when the roller rotates. The driving module 400 also includes a power component for driving the roller to rotate, such as a motor, a motor, etc. Furthermore, the cleaning device also includes a cleaning module 500, which is located on the front side of the cleaning component 200 in the first direction. The cleaning module 500 has a cleaning structure such as a brush. When the brush contacts the working surface, it can remove large particles of impurities such as hair and debris on the working surface. When the cleaning device is in working state, as the cleaning device as a whole moves along the first direction, the cleaning module 500 and the cleaning component 200 pass through the working surface of a certain area in turn. The working surface is first cleaned by the cleaning module 500 to remove dirt such as hair and large particles of impurities, and then the cleaning component 200 wipes and mops the working surface of the area, so that the cleaning of the working surface is more thorough and the probability of failure of the cleaning equipment can be reduced.

[0045] It can be understood that the opening 120 is located in front of the scraper 310 in the second direction. Therefore, the outer surface of the cleaning component 200 will first pass through the scraper 310 to scrape off the dirt and sewage on the surface, and then be exposed to the opening 120. Therefore, the area where the cleaning component 200 contacts the working surface has been cleaned, so that the cleaning component 200 can continue to clean the working surface in a clean state to ensure the cleaning effect.

[0046] like Figure 1As shown, the main body 100 has scraping teeth 150 arranged toward the cleaning component 200, part of the cleaning component 200 is located between the scraping teeth 150 and the scraping member 310, and the scraping teeth 150 are located in front of the scraping member 310 in the second direction, so that the area after the cleaning component 200 contacts the working surface first passes through the scraping teeth 150, and the scraping teeth 150 can scrape off large particles of impurities such as hair attached to the surface of the cleaning component 200, and the hair-like impurities can be entangled on the scraping teeth 150, and the scraping teeth 150 perform preliminary cleaning on the surface of the cleaning component 200, so as to prevent excessive dirt from entering the dirt storage box 320, and extend the cleaning frequency of the dirt storage box 320. The scraping teeth 150 are arranged in a sawtooth shape, and extend along the axial direction of the cleaning component 200 as a whole, so that the entire circumference of the cleaning component 200 can be preliminarily cleaned by the scraping teeth 150.

[0047] In one embodiment, the water injection hole 140 is arranged to be higher than the sewage inlet 130 and is located above the cleaning component 200. Therefore, the cleaning liquid introduced from the water injection hole 140 can flow directly downward to the surface of the cleaning component 200 under the action of gravity to clean the cleaning component 200. The sewage formed after the cleaning component 200 is cleaned can also flow downward and be discharged into the sewage storage box 320 through the sewage inlet 130. In addition, the sewage inlet 130 is located above the scraping member 310. The sewage and dirt scraped off the surface of the cleaning component 200 by the scraping member 310 are intercepted above the scraping member 310 and are directly discharged into the sewage storage box 320 through the sewage inlet 130.

[0048] It should be noted that, in the present invention, the height direction of the cleaning device is taken as a reference, the top of the cleaning device in the height direction is taken as the upper side, and the bottom of the cleaning device in the height direction is taken as the lower side. The water injection hole 140 is located above the drum 210, which means that the water injection hole 140 is higher than the highest point of the cleaning assembly 200, so as to ensure that the cleaning liquid introduced from the water injection hole 140 can flow directly toward the cleaning assembly 200 and clean the cleaning assembly 200. Specifically, the water injection hole 140 is located directly above the cleaning assembly 200, that is, the water injection hole 140 is located directly above the rotation axis of the cleaning assembly 200, and the cleaning liquid flowing out of the water injection hole 140 flows directly downward to the surface of the cleaning assembly 200, so as to ensure that the cleaning liquid can fully act on the cleaning assembly 200 and reduce waste; it should be noted that, in view of the processing and assembly errors, the water injection hole 140 is not strictly limited to be aligned with the rotation axis of the cleaning assembly 200 in the vertical direction, and the water injection hole 140 and the rotation axis of the cleaning assembly 200 are allowed to be misaligned in the vertical direction.

[0049] Alternatively, the water injection hole 140 is located directly above the cleaning component 200, and the water injection hole 140 is set toward the sewage inlet 130. In this way, the cleaning liquid flowing out of the water injection hole 140 can all flow to the side of the cleaning component 200 facing the sewage inlet 130, and finally be discharged into the sewage storage box 320 through the sewage inlet 130, thereby preventing the cleaning liquid from flowing to other areas of the cleaning component 200, causing the cleaning liquid to flow out of the installation cavity 110 and contaminate the working surface.

[0050] It can be understood that there are multiple water injection holes 140, and the multiple water injection holes 140 are arranged at intervals along the axial direction of the cleaning component 200. The cleaning liquid flowing out from different water injection holes 140 can take into account the cleaning of different areas in the axial direction of the cleaning component 200, thereby improving the cleaning effect of the cleaning component 200. In addition, a drainage channel is provided in the main body 100, and the drainage channel extends along the axial direction of the cleaning component 200. Each water injection hole 140 is connected to the drainage channel, and one end of the drainage channel is connected to the water inlet pipe. The cleaning liquid is introduced into the drainage channel through the water inlet pipe and discharged through different water injection holes 140. In addition, a water injection head is provided on the inner wall of the main body 100, and the water injection head is protruding toward the cleaning component 200. The water injection hole 140 is provided through the water injection head. The provision of the water injection head can make the water injection hole 140 close to the surface of the cleaning component 200, thereby improving the cleaning effect of the cleaning component 200.

[0051] A portion of the inner wall of the main body 100 forms a guide wall 160, and the top of the scraper 310 has a guide surface 311. The guide wall 160 is located above the guide surface 311. The guide wall 160 and the guide surface 311 jointly define the sewage inlet 130. The guide wall 160 and the guide surface 311 are both tilted downward away from the cleaning component 200. The guide wall 160 and the guide surface 311 guide the sewage and dirt scraped from the cleaning component 200 so that the sewage and dirt can enter the dirt storage box 320 more smoothly. It should be noted that the guide wall 160 and the guide surface 311 are tilted downward, which means that the guide wall 160 and the guide surface 311 have a tendency to extend downward away from the cleaning component 200. Under this premise, the guide wall 160 and the guide surface 311 can be set as an inclined surface, a curved surface, a curved surface, etc.

[0052] The dirt storage box 320 is connected to the side of the scraper 310 facing away from the cleaning component 200 and is located below the guide wall 160. Since the guide wall 160 and the guide surface 311 both have a tendency to tilt downward away from the cleaning component 200, the sewage flowing down from the surface of the cleaning component 200 or from the installation cavity 110 is guided by the guide wall 160 and is directed to the dirt storage box 320. The sewage and dirt scraped off from the surface of the cleaning component 200 by the scraper 310 are intercepted at the guide surface 311 and are guided by the guide surface 311 and discharged into the dirt storage box 320.

[0053] Furthermore, one end of the dirt scraper 310 is in contact with the outer surface of the cleaning assembly 200, and the other end is connected to the top of the dirt storage box 320. Therefore, the dirt storage box 320 is lower than the dirt scraper 310, which can prevent the sewage and dirt entering the dirt storage box 320 from flowing back. In addition, the opening of the dirt inlet 130 is gradually reduced in the direction away from the cleaning assembly 200. On the one hand, it is convenient for the sewage and dirt to be discharged into the dirt storage box 320 through the dirt inlet 130, and on the other hand, it reduces the probability of the sewage and dirt in the dirt storage box 320 flowing out; the opening of the dirt inlet 130 refers to the distance between the guiding wall 160 and the guiding surface 311.

[0054] In one embodiment, the dirt storage box 320 is connected to the side of the scraping member 310 facing away from the cleaning assembly 200, and the side of the dirt storage box 320 facing away from the scraping member 310 abuts against the main body 100, so that the sewage discharge structure 300 is clamped between the cleaning assembly 200 and the main body 100 as a whole. When the sewage discharge structure 300 is installed, the opposite ends thereof are respectively abutted against the cleaning assembly 200 and the main body 100, and the sewage discharge structure 300 can be assembled to the main body 100; when the sewage discharge structure 300 needs to be disassembled, after the cleaning assembly 200 is taken out, the sewage discharge structure 300 is pushed toward the installation cavity 110, and the sewage discharge structure 300 can be taken out, and the disassembly and assembly of the sewage discharge structure 300 is relatively convenient.

[0055] Furthermore, the scraper 310 and the dirt storage box 320 are provided as an integral connection structure, and the scraper 310 and the dirt storage box 320 do not need to be assembled separately, and the dirt discharge structure 300 can be directly assembled with the main body 100, and the dirt discharge structure 300 and the main body 100 are easy to assemble and disassemble.

[0056] In addition, the dirt scraping member 310 and the dirt storage box 320 are both provided with corresponding structures capable of limiting the position of the main body 100, so that the connection between the dirt discharge structure 300 and the main body 100 is more stable. Figure 3 and Figure 4The main body 100 includes a first limiting portion 170 and a second limiting portion 180, the scraping member 310 has a first connecting portion 312, and the dirt storage box 320 has a second connecting portion 321. The first limiting portion 170 abuts against the first connecting portion 312 toward the cleaning component 200, so that the first connecting portion 312 is abutted by the first limiting portion 170 toward the cleaning component 200, and the second limiting portion 180 abuts against the second connecting portion 321 toward the cleaning component 200, so that the second connecting portion 321 is abutted by the second limiting portion 180 toward the cleaning component The first limit portion 170 is used to limit the contact area between the first limit portion 170 and the cleaning component 200, so that the scraping member 310 can maintain a stable position. At the same time, the dirt storage box 320 is clamped between the second limit portion 180 and the cleaning component 200. When the cleaning device is in working state, the scraping member 310 can maintain a stable contact state with the cleaning component 200 and scrape off the dirt on the surface of the cleaning component 200.

[0057] like Figure 6 As shown, the first connecting portion 312 is disposed at the top of the scraping member 310 and is located in the middle of the scraping member 310 in the axial direction of the cleaning assembly 200 to avoid the guide surface 311, so that sewage and dirt can enter the dirt storage box 320 through the guide surface 311; Figure 3 The first limiting portion 170 is disposed on the inner wall of the main body 100 and protrudes toward the cleaning assembly 200. The first limiting portion 170 and the first connecting portion 312 abut against each other in the first direction. The second connecting portion 321 may be a side wall of the dirt storage box 320 facing away from the cleaning assembly 200. The second limiting portion 180 is located on the side of the second connecting portion 321 facing away from the cleaning assembly 200 and abut against each other in the first direction.

[0058] The main body 100 further includes a covering portion 190, and the first limiting portion 170 and the second limiting portion 180 are respectively connected to opposite ends of the covering portion 190 along the first direction. The covering portion 190 is located at the top of the dirt storage box 320 and covers the dirt storage box 320 to isolate the dirt storage box 320 from the external environment. The first limiting portion 170 protrudes toward the cleaning assembly 200 relative to the covering portion 190 and cooperates with the first connecting portion 312 to abut against the second connecting portion 321, and the second limiting portion 180 protrudes downward relative to the covering portion 190 and cooperates with the second connecting portion 321 to abut against the second connecting portion 321.

[0059] Further, the first limiting portion 170 and the first connecting portion 312 are mutually limited in the vertical direction, and the second connecting portion 321 and the second limiting portion 180 are mutually limited in the vertical direction, so that the sewage discharge structure 300 is simultaneously limited in the vertical direction and in the first direction by the combination of the main body 100 and the cleaning assembly 200, and the position of the sewage discharge structure 300 is more stable. The limiting method of the first limiting portion 170 and the first connecting portion 312 in the vertical direction, and the limiting method of the second connecting portion 321 and the second limiting portion 180 in the vertical direction are not limited to plugging, clamping, etc.

[0060] Exemplarily, the first limiting part 170 and the first connecting part 312 are mutually engaged, and realize mutual limiting in the vertical direction and the first direction at the same time; or, one of the second limiting part 180 and the second connecting part 321 has a limiting hole, and the other has a limiting protrusion, the limiting protrusion is inserted into the limiting hole in the horizontal direction, and the inner wall of the limiting hole and the limiting protrusion are mutually abutted in the vertical direction, so as to realize the vertical limiting of the second limiting part 180 and the second connecting part 321. It can be understood that the second limiting part 180 and the second connecting part 321 connected in a plug-in manner can also limit each other in the axial direction of the cleaning component 200 to prevent the scraping member 310 from moving in the axial direction of the cleaning component 200; the second limiting part 180 and the second connecting part 321 can be provided in plurality, and arranged at intervals along the axial direction of the cleaning component 200, so that the sewage discharge structure 300 is limited by the main body 100 in different areas in the axial direction of the cleaning component 200.

[0061] In addition, refer to Figure 4 The sewage discharge structure 300 is provided with a first abutting portion 330 at both ends of the cleaning component 200 in the axial direction, and the interior of the main body 100 is provided with a second abutting portion 101 protruding toward the installation cavity 110, and the first abutting portion 330 abuts against the top of the second abutting portion 101, and the first abutting portion 330 is clamped between the second abutting portion 101 and the bottom surface of the sewage discharge box. Both ends of the sewage discharge structure 300 are limited in the vertical direction by the main body 100, so that the sewage discharge structure 300 maintains balance in the axial direction of the cleaning component 200, ensuring that the scraping member 310 is stably abutted against the surface of the cleaning component 200.

[0062] The dirt storage box 320 is also provided with a concave pit 322 at the end of the cleaning component 200 in the axial direction, and the inner wall of the main body 100 in the axial direction of the cleaning component 200 is provided with a convex rib 102 protruding toward the dirt discharge structure 300, and the convex rib 102 can be inserted into the pit 322. When the dirt discharge structure 300 is assembled to the main body 100, the dirt discharge structure 300 is pushed along the radial direction of the cleaning component 200, so that the second connection part 321 is constantly close to the second limit part 180, and when the convex rib 102 is inserted into the pit 322, the second connection part 321 and the second limit part 180 are abutted, and the cooperation between the convex rib 102 and the pit 322 can indicate to the user whether the dirt discharge structure 300 is assembled in place, so that the dirt discharge structure 300 has a high degree of installation convenience.

[0063] Reference Figure 3 and Figure 5 The sewage discharge structure 300 is also provided with a handle 340, which is connected to the side of the sewage storage box 320 facing the cleaning assembly 200. The handle 340 is provided for the user to hold the sewage discharge structure 300 so as to facilitate the disassembly and assembly of the sewage discharge structure 300 to the main body 100. The handle 340 is recessed upward relative to the bottom surface of the sewage storage box 320, which provides a space for the user's hand to hold on the one hand, and avoids interference with the working surface and affecting the movement of the cleaning device on the other hand.

[0064] Reference Figure 6 and Figure 7 The cleaning device further includes a sewage tank 600 and a sewage pipe 700. A plurality of intervally arranged sewage blocking protrusions 323 are provided in the sewage storage box 320. The sewage blocking protrusions 323 protrude upward based on the bottom wall of the sewage storage box 320. The plurality of sewage blocking protrusions 323 are arranged to form a sewage cavity 324. The sewage blocking protrusions 323 can intercept large particles of impurities such as hair outside the sewage cavity 324. The sewage enters the sewage cavity 324 through the gaps between the sewage blocking protrusions 323 and is temporarily stored in the sewage cavity 324. The two ends of the sewage pipe 700 are respectively connected to the sewage tank 600 and the sewage cavity 324. The sewage in the sewage cavity 324 is discharged into the sewage tank 600 through the sewage pipe 700 and can be discharged through the sewage tank 600. Under the interception effect of the sewage blocking protrusions 323 on large particles of impurities, only sewage is allowed to enter the sewage tank 600 through the sewage pipe 700, thereby reducing the probability of blockage of the sewage pipe 700 and failure of the cleaning device.

[0065] A dam 325 is also provided on the bottom wall of the dirt storage box 320, and the dirt blocking protrusion 323 is connected to the top of the dam 325; after the dirt enters the dirt storage box 320 through the dirt inlet 130, large particles or impurities with a certain weight are deposited on the bottom wall of the dirt storage box 320 and are blocked by the dam 325. The dam 325 and the dirt blocking protrusion 323 are combined to intercept the impurities, which can further reduce the probability of impurities entering the sewage chamber 324.

[0066] In addition, a dirt storage chamber 326 is further provided in the dirt storage box 320, and the dirt storage chamber 326 is connected to the sewage chamber 324 through the gap between the dirt blocking protrusions 323. A plurality of spaced dirt storage protrusions 327 are provided in the dirt storage chamber 326, and the dirt storage protrusions 327 can also intercept large particles of impurities. As sewage and dirt flow in the dirt storage box 320, hair impurities can be intercepted and entangled on the dirt storage protrusions 327 or the dirt blocking protrusions 323. The dirt storage chamber 326 provides storage space for large particles of impurities, thereby preventing impurities from accumulating and clogging the gaps between the dirt blocking protrusions 323, affecting the entry of sewage into the sewage chamber 324, and extending the cleaning frequency of the dirt storage box 320.

[0067] It can be understood that the dirt blocking protrusion 323 has a space for storing and flowing sewage and dirt between the scraping member 310 in the first direction; the dirt storage chamber 326 and the sewage chamber 324 are distributed along the axial direction of the cleaning component 200, and the sewage chamber 324 is closer to the sewage guide pipe 700, so that the sewage is concentrated in the area of ​​the dirt storage box 320 close to the sewage guide pipe 700, which facilitates the sewage guide pipe 700 to guide the sewage into the sewage tank 600.

[0068] The sewage storage box 320 also has an adsorption part, which is located at the lowest point of the bottom wall of the sewage chamber 324, that is, the sewage in the sewage chamber 324 has the lowest liquid level at the adsorption part, and the sewage remaining in the sewage chamber 324 is concentrated in the adsorption part. One end of the sewage guide pipe 700 extends to the adsorption part, which can absorb the sewage remaining in the sewage storage box 320 and discharge it into the sewage tank 600, so that the sewage in the sewage chamber 324 can be discharged more thoroughly, reducing the sewage residue in the sewage storage box 320.

[0069] It can be understood that part of the bottom wall of the sewage chamber 324 is recessed downward to form the adsorption portion; or, the adsorption portion is configured as a groove or a hole located on the bottom wall of the sewage chamber 324 .

[0070] It should be noted that the cleaning equipment in the present invention can be a vacuum cleaner, a floor scrubber, a floor washing robot, a road cleaning machine, etc.; in one embodiment, the cleaning equipment is configured as a sweeping robot, the cleaning component contacts the ground and cleans the ground, and after the surface of the cleaning component passes through the scraping member, the sewage and dirt on its surface have been discharged and will no longer pollute the working surface, and there is no need to additionally set up a structure for scraping off the sewage on the working surface, which is more convenient to use. In addition, the speed of the surface of the cleaning component relative to the ground is relatively large, which can increase the degree of friction between the ground and the working surface, making the cleaning of the working surface more thorough.

[0071] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
