Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0148] The cleaning assembly 100 , the main body of the cleaning device, and the cleaning device according to an embodiment of the present application are described below with reference to FIG. 1 and FIG. 2 .

[0149] An embodiment of the present application provides a cleaning assembly 100 , as shown in FIG1 . The cleaning assembly 100 includes a mounting frame 110 , a rolling cleaning member 120 , and a driving mechanism.

[0150] As shown in FIG1 , the mounting bracket 110 may include a mounting base 111 and a mounting cover 112 . The mounting cover 112 is mounted on the bottom of the mounting base 111 . The mounting cover 112 and the mounting base 111 may be connected by threaded connection, bonding, welding, snap connection or other means.

[0151] As shown in Figures 1 and 2, the mounting frame 110 defines a accommodating cavity 113, the bottom of the mounting seat 111 defines a cavity, and the mounting cover 112 is a hollow structure. When the mounting seat 111 and the mounting cover 112 are installed together, the cavity at the bottom of the mounting seat 111 and the hollow part of the mounting cover 112 are connected to form the accommodating cavity 113, that is, the bottom of the accommodating cavity 113 is an opening.

[0152] As shown in FIG. 1 and FIG. 2 , a scraper 114 is provided on the inner wall surface of the accommodating cavity 113 . The scraper 114 protrudes into the accommodating cavity 113 .

[0153] The scraper bar 114 includes at least a first wiper portion 1141 , the extension direction of which is non-parallel to the axial direction of the rolling cleaning member 120 , so that the sewage scraped by the first wiper portion 1141 can flow at the first wiper portion 1141 , thereby facilitating the collection of the scraped sewage.

[0154] The scraper bar 114 may be a whole scraper bar extending from the first axial end of the accommodating cavity 113 to the second axial end of the accommodating cavity 113 , or there may be multiple scrapers 114 distributed along the axial direction of the accommodating cavity 113 .

[0155] As shown in Figures 1 and 2, the mounting frame 110 is provided with a water outlet 115 connected to the accommodating chamber 113. The water outlet 115 is used to discharge sewage. The water outlet 115 can be provided at the upper end of the mounting frame 110, or at the front side, rear side or other position of the mounting frame 110.

[0156] As shown in FIG. 1 and FIG. 2 , one end of the water outlet 115 is communicated with the accommodating chamber 113 , and the other end of the water outlet 115 can be communicated with a box body for collecting sewage, so that the discharged sewage can be collected in the box body.

[0157] As shown in Figure 1, the rolling cleaning member 120 is rotatably installed in the accommodating cavity 113. The rolling cleaning member 120 may include a rolling cleaning member body 122 and a mop 121. The rolling cleaning member body 122 is rotatably installed in the accommodating cavity 113, and the mop 121 is installed on the outer periphery of the rolling cleaning member body 122. The mop 121 is used to clean the floor.

[0158] The rolling cleaning member 120 may be designed in various forms, including but not limited to a flat plate structure, a drum structure, and a crawler structure.

[0159] For example, in some embodiments, as shown in FIG1 , the rolling cleaning member 120 is designed as a drum-type structure.

[0160] For example, in other embodiments, the rolling cleaning member 120 is designed as a crawler structure. Specifically, the crawler structure can generally adopt an annular mop 121 to provide a continuous cleaning surface. The rolling cleaning member body 122 includes a crawler rotating assembly. The crawler rotating assembly includes an active part and a driven part. The active part drives the driven part through the annular mop 121, thereby realizing the movement of the crawler. The mop 121 has the dual action of parallel movement and rotation with the crawler rotating assembly.

[0161] It should be noted that when the rolling cleaning member 120 is designed as a drum structure, the cross section of the rolling cleaning member 120 is circular. When the rolling cleaning member 120 is designed as a crawler structure, the cross section of the rolling cleaning member 120 is non-circular, specifically, it can be waist-shaped, elliptical or oval.

[0162] As shown in Figure 1, the outer periphery of the rolling cleaning member 120 is spaced apart from the inner wall surface of the accommodating chamber 113, and the first wiper portion 114 of the scraper bar 114 abuts against the outer surface of the rolling cleaning member 120. The mop 121 located on the outer periphery of the rolling cleaning member body 122 is spaced apart from the inner wall surface of the accommodating chamber 113. The height of the scraper bar 114 is greater than the distance between the mop 121 and the inner wall surface of the accommodating chamber 113. One side of the scraper bar 114 is connected to the inner wall surface of the accommodating chamber 113, and the side of the scraper bar 114 opposite the inner wall surface of the accommodating chamber 113 abuts against the mop 121 to apply pressure to the mop 121. The output end of the drive mechanism is power-coupled to the rolling cleaning member 120 for driving the rolling cleaning member 120 to rotate about the axis in the first direction X or the second direction Y. The drive mechanism can be a motor, a lead screw nut, or other device.

[0163] As shown in FIG1 , the first direction X may be the clockwise direction in FIG1 , and the second direction Y may be the counterclockwise direction in FIG1 . In other embodiments, depending on the position of the scraper strip 114 , the first direction X may also be the counterclockwise direction in FIG1 , and the second direction Y may also be the clockwise direction in FIG1 .

[0164] During actual implementation, when the cleaning assembly 100 is used to clean the floor, the mop 121 needs to be wetted, and the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X. At this time, the scraping bar 114 applies pressure to the mop 121, and scrapes off the sewage and impurities on the mop 121 when the rolling cleaning member 120 rotates. The scraped sewage is discharged from the water outlet 115. Since the gap between the mop 121 and the inner wall surface of the accommodating chamber 113 is small, and the scraping bar 114 is blocked in the gap between the mop 121 and the inner wall surface of the accommodating chamber 113, the rolling cleaning member 120 can drive the impurities to move circumferentially toward the scraping bar 114 when rotating, and the impurities are gathered at the scraping bar 114 under the obstruction of the scraping bar 114; when the cleaning assembly 100 is finished cleaning, the driving mechanism can be used to drive the rolling cleaning member 120 to move along the second direction Y. At this time, the rotation of the rolling cleaning member 120 drives the impurities to move circumferentially away from the scraping bar 114 and be discharged from the opening at the bottom of the accommodating chamber 113.

[0165] By using the driving mechanism to drive the rolling cleaning member 120 to rotate along the first direction X or the second direction Y, the scraping bar 114 can scrape off the dirty water and impurities on the mop 121 when the rolling cleaning member 120 rotates along the first direction X, and the scraped impurities are gathered at the scraping bar 114, that is, the scraping bar 114 is used to clean the mop 121 that absorbs the dirt and impurities in real time when the cleaning component 100 cleans the floor, so that the cleaning component 100 can always use the clean mop 121 to clean the floor, reducing the secondary damage caused by the dirt and impurities on the mop 121 to the floor. Contamination, when the rolling cleaning member 120 rotates along the second direction Y, the rolling cleaning member 120 can be used to drive the accumulated impurities to move circumferentially in the direction away from the scraper 114, and be discharged from the opening at the bottom of the accommodating chamber 113. There is no need to remove the rolling cleaning member 120 to clean the impurities in the gap, which can improve the cleaning efficiency of the mop 121, reduce the user's operating steps, improve the automation of the cleaning component 100, and reduce the probability of impurities accumulating in the gap between the rolling cleaning member 120 and the inner wall surface of the accommodating chamber 113 and affecting the rotation continuity of the rolling cleaning member 120.

[0166] According to the cleaning component 100 provided in the embodiment of the present application, by utilizing a driving mechanism to drive the rolling cleaning member 120 to rotate along the first direction X or the second direction Y, impurities scraped out and accumulated in the gaps can be automatically discharged, thereby reducing the user's operating steps and improving the automation and intelligence of the cleaning component 100. At the same time, the mop 121 can be cleaned in real time when the cleaning component 100 cleans the floor without returning to the base station, thereby reducing the probability of dirt and impurities on the mop 121 causing secondary contamination to the floor and improving the cleaning effect and cleaning efficiency.

[0167] In some embodiments, as shown in FIG. 1 , when the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X, the scraping bar 114 is used to scrape out the sewage and / or collect impurities on the periphery of the rolling cleaning member 120 .

[0168] When the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X, the scraping bar 114 can be used to scrape out the sewage around the rolling cleaning member 120 and collect impurities around the rolling cleaning member 120 .

[0169] In other embodiments, when the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X, the scraper bar 114 is used to scrape out the sewage around the rolling cleaning member 120, and the second wiper portion or other structure of the scraper bar 114 is used to collect impurities around the rolling cleaning member 120.

[0170] In some other embodiments, when the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X, the scraper bar 114 is used to collect impurities on the periphery of the rolling cleaning member 120, and the sewage on the periphery of the rolling cleaning member 120 is scraped out by the second wiper portion or other structure of the scraper bar 114.

[0171] When the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X, the scraping bar 114 is used to scrape out the sewage and / or collect impurities on the periphery of the rolling cleaning member 120, thereby improving the utilization rate of the scraping bar 114 and reducing the production cost to a certain extent.

[0172] In some embodiments, the cleaning assembly 100 has a first working mode. When the cleaning assembly 100 is in the first working mode, the driving mechanism drives the rolling cleaning member 120 to rotate along a first direction.

[0173] During the actual implementation process, when the cleaning component 100 is in the first working mode, the driving mechanism drives the rolling cleaning member 120 to rotate along the first direction X. At this time, the cleaning component 100 is in the working mode of cleaning the ground, and the rolling cleaning member 120 can be used to clean the surface to be cleaned. While cleaning the surface to be cleaned, the first wiper part can be used to clean the rolling cleaning member 120.

[0174] By setting the above-mentioned first working mode, the rolling cleaning element can be cleaned while cleaning the surface to be cleaned, thereby reducing the probability of impurities causing secondary contamination to the ground when the cleaning component 100 rotates the rolling cleaning element 120 along the second direction Y when cleaning the ground.

[0175] In some embodiments, when the driving mechanism drives the rolling cleaning member 120 to rotate along the second direction Y, the rolling cleaning member 120 is used to discharge the collected impurities out of the accommodating cavity 113 .

[0176] When the driving mechanism drives the rolling cleaning member 120 to rotate along the second direction Y, the cleaning assembly 100 is in a self-cleaning working mode after cleaning is completed.

[0177] When the driving mechanism drives the rolling cleaning member 120 to rotate along the second direction Y, the rolling cleaning member 120 is used to discharge the collected impurities from the accommodating cavity 113, which can facilitate the cleaning component 100 to discharge internal impurities after cleaning is completed, thereby improving the self-cleaning efficiency of the cleaning component 100.

[0178] In some embodiments, the cleaning assembly 100 has a second working mode. When the cleaning assembly 100 is in the second working mode, the driving mechanism drives the rolling cleaning member 120 to rotate along the second direction.

[0179] During the actual implementation process, when the cleaning component 100 is in the second working mode, the driving mechanism drives the rolling cleaning member 120 to rotate along the second direction Y. At this time, the cleaning component 100 is in the self-cleaning mode. During the rotation along the second direction Y, the rolling cleaning member 120 can bring the scraped impurities out to the outside of the cleaning component 100.

[0180] By setting the second working mode, the cleaning component 100 can perform a self-cleaning operation after cleaning is completed, thereby reducing the user's workload and further improving the user's experience.

[0181] In some embodiments, as shown in FIG. 2 , the wiper strip 114 includes a first wiper portion 1141 and a second wiper portion 1142 connected to each other. The first wiper portion 1141 and the second wiper portion 1142 extend from the connecting portion to both axial ends of the mounting frame 110 , respectively.

[0182] It should be noted that when the rolling cleaning member 120 is a drum-type structure, the axial direction of the mounting frame 110 is parallel to the rotation axis of the rolling cleaning member 120; when the rolling cleaning member 120 is designed as a crawler-type structure, the axial direction of the mounting frame 110 is parallel to the rotation axis of the active part or the driven part of the rolling cleaning member 120.

[0183] As shown in FIG. 2 , the connection portion between the first wiper portion 1141 and the second wiper portion 1142 may be located in the axial middle portion of the mounting frame 110 , or may be located at other axial positions of the rolling cleaning member 120 .

[0184] As shown in Figure 2, the first end of the first wiper portion 1141 can be located at the axial first end of the mounting frame 110, the second end of the first wiper portion 1141 is connected to the first end of the second wiper portion 1142, and the second end of the second wiper portion 1142 can be located at the axial second end of the mounting frame 110.

[0185] By arranging the first wiper portion 1141 and the second wiper portion 1142 to extend from the connection portion of the first wiper portion 1141 and the second wiper portion 1142 toward the axial ends of the mounting frame 110 respectively, the overall length of the scraper bar 114 can be extended, thereby increasing the abutment area between the scraper bar 114 and the rolling cleaning member 120, that is, increasing the cleaning area of ​​the scraper bar 114 on the rolling cleaning member 120, thereby improving the cleaning effect of the scraper bar 114 on the rolling cleaning member 120.

[0186] In some embodiments, when the rolling cleaning member 120 rotates along the first direction X, in the circumferential direction of the rolling cleaning member 120, the position where the first wiper portion 1141 and the second wiper portion 1142 close to the axial end of the mounting frame 110 abut against the rolling cleaning member 120 is located upstream of the position where the connecting portion abuts against the rolling cleaning member 120 along the first direction X.

[0187] It should be noted that, when the rolling cleaning member 120 is a drum-type structure, the circumferential direction of the rolling cleaning member 120 is along the direction of the outer contour of the circular cross-section; when the rolling cleaning member 120 is designed as a crawler-type structure, the circumferential direction of the rolling cleaning member 120 is along the direction of the outer contour of the non-circular cross-section, and the non-circular cross-section here can be waist-shaped, elliptical or oval, and surrounds the axis of the active part and the driven part.

[0188] Among them, the projections of the first wiper portion 1141 and the second wiper portion 1142 along the axial direction of the rolling cleaning member 120 are both line segments, and the height of the first end of the first wiper portion 1141 is higher than the height of the second end of the first wiper portion 1141, and the height of the second end of the second wiper portion 1142 is higher than the height of the first end of the second wiper portion 1142, that is, the first wiper portion 1141 and the second wiper portion 1142 are arranged at an angle.

[0189] During the actual implementation process, when the scraper bar 114 scrapes off the sewage and impurities on the mop 121, since the height of the two ends of the scraper bar 114 is higher than the height of the connection between the first wiper part 1141 and the second wiper part 1142, the sewage scraped off from the two ends of the scraper bar 114 will gather at the connection between the first wiper part 1141 and the second wiper part 1142 under the action of its own gravity.

[0190] By setting the position on the rolling cleaning member 120 where the first wiper portion 1141 and the second wiper portion 1142 abut against one end of the rolling cleaning member 120 near the axial end of the mounting frame 110 to be upstream of the position on the rolling cleaning member 120 where the first wiper portion 1141 and the second wiper portion 1142 abut against one end of the rolling cleaning member 120 and the connecting portion, the sewage scraped out from both ends of the scraping strip 114 can be collected at the connecting portion, thereby facilitating subsequent centralized treatment of the sewage, reducing the probability of secondary pollution to the ground caused by water accumulation at both ends resulting in leakage of the cleaning assembly 100, and further improving the cleaning effect of the rolling cleaning member.

[0191] In some embodiments, the water outlet 115 is close to the connection portion.

[0192] The water outlet 115 is close to the connection portion between the first wiper portion 1141 and the second wiper portion 1142 , that is, the water outlet 115 may be located in the middle of the wiper strip 114 .

[0193] During the actual implementation process, when the scraper bar 114 scrapes off the sewage and impurities on the mop 121, since the height of the two ends of the scraper bar 114 is higher than the height of the connection between the first wiper part 1141 and the second wiper part 1142, the sewage scraped off from the two ends of the scraper bar 114 will gather at the connection between the first wiper part 1141 and the second wiper part 1142 under the action of its own gravity, and be discharged through the water outlet 115 located at the connection between the first wiper part 1141 and the second wiper part 1142.

[0194] By arranging the water outlet 115 at the connection portion, the sewage scraped from both ends of the scraping bar 114 can be collected at the connection portion and discharged from the water outlet 115 , thereby improving the sewage discharge efficiency.

[0195] In some embodiments, as shown in Figure 2, when the cross-section of the rolling cleaning member 120 is circular, the projection of the first wiper portion 1141 and / or the second wiper portion 1142 on the first vertical plane is located above the projection of the axis of the rolling cleaning member 120 on the first vertical plane, the projection of the first wiper portion 1141 and / or the second wiper portion 1142 on the first vertical plane is a line segment and has a specific angle with the projection line of the axis of the rolling cleaning member 120 on the first vertical plane, and the distance from the projection of the connecting portion on the first vertical plane to the projection line of the axis of the rolling cleaning member 120 on the first vertical plane is less than the distance from other points of the projection line of the first wiper portion 1141 and / or the second wiper portion 1142 on the first vertical plane to the projection line of the axis of the rolling cleaning member 129 on the first vertical plane.

[0196] When the cross-section of the rolling cleaning member 120 is non-circular, the projection of the first wiper portion 1141 and / or the second wiper portion 1142 on the first vertical plane is located above the projection of the reference line of the rolling cleaning member 120 on the first vertical plane, and the projection of the first wiper portion 1141 and / or the second wiper portion 1142 on the first vertical plane is a line segment and is parallel to or has a specific angle with the projection line of the reference line of the rolling cleaning member 120 on the first vertical plane.

[0197] The first vertical plane may be parallel to the axis of the rolling cleaning member 120 or may be arranged at an acute angle to the axis of the rolling cleaning member 120. The reference line of the rolling cleaning member 120 may be a symmetry line of the cross-section center, or the reference line of the rolling cleaning member 120 may be parallel to the axis of the active portion or the driven portion, and the geometric center of the cross section is located on the reference line of the rolling cleaning member.

[0198] It should be noted that the line segment formed by the projection of the first wiper portion 1141 and / or the second wiper portion 1142 on the first vertical plane may be, but is not limited to, a straight line segment, a curved line segment or a broken line segment, etc., and this application does not impose any limitation on this.

[0199] The distance between the end of the projection line of the first wiper portion 1141 in the first vertical plane facing away from the connecting portion and the projection line of the axis of the rolling cleaning member 120 in the first vertical plane is the largest, and the distance between the other parts of the projection line of the first wiper portion 1141 in the first vertical plane and the projection line of the axis of the rolling cleaning member 120 in the first vertical plane gradually decreases; the distance between the end of the projection line of the second wiper portion 1142 in the first vertical plane facing away from the connecting portion and the projection line of the axis of the rolling cleaning member 120 in the first vertical plane is the largest, and the distance between the other parts of the projection line of the second wiper portion 1142 in the first vertical plane and the projection line of the axis of the rolling cleaning member 120 in the first vertical plane gradually decreases, that is, the first wiper portion 1141 and the second wiper portion 1142 form a V-shaped structure as a whole.

[0200] As shown in Figure 2, the height of the first wiper portion 1141 can be gradually lowered from the position of the axial end of the mounting frame 110 to the position of the connecting portion, the height of the second wiper portion 1142 can be gradually lowered from the position of the axial end of the mounting frame 110 to the position of the connecting portion, or the height of both the first wiper portion 1141 and the second wiper portion 1142 can be gradually lowered from the position of the axial end of the mounting frame 110 to the position of the connecting portion.

[0201] The heights of the first wiper portion 1141 and the second wiper portion 1142 from the position of the axial end of the mounting frame 110 to the position of the connecting portion may decrease linearly, or may decrease exponentially, or gradually decrease in other ways, that is, the first wiper portion 1141 and the second wiper portion 1142 may be a linear structure, an arc structure, a wave structure or other shape structures. For example, as shown in FIG2 , the heights of the first wiper portion 1141 and the second wiper portion 1142 from the position of the axial end of the mounting frame 110 to the position of the connecting portion decrease linearly, and the first wiper portion 1141 and the second wiper portion 1142 are both linear structures.

[0202] During actual implementation, when the scraper bar 114 scrapes off the sewage and impurities on the mop 121, since the heights of the first wiper portion 1141 and the second wiper portion 1142 gradually decrease from the axial end position of the mounting frame 110 to the connection position, the sewage scraped out by the parts of the scraper bar 114 on both sides of the axial direction converge at the connection portion along the first wiper portion 1141 and the second wiper portion 1142 under the action of their own gravity and are discharged from the water outlet 115.

[0203] Through the arrangement of the above-mentioned first wiper portion 1141 and the second wiper portion 1142, the sewage from the axial end of the mounting frame 110 to various positions of the connecting portion of the first wiper portion 1141 and the second wiper portion 1142 can be automatically gathered at the connecting portion, thereby further improving the sewage discharge efficiency and further reducing the probability of secondary pollution to the ground caused by leakage of the cleaning component 100 due to water accumulation at both ends.

[0204] In some embodiments, as shown in FIG. 1 and FIG. 2 , the height of the scraping strip 114 is lower than the height of the highest point of the rolling cleaning member 120 and higher than the height of the axis of the rolling cleaning member 120 .

[0205] As shown in Figures 1 and 2, the height of each position on the scraper bar 114 is lower than the height of the highest point of the rolling cleaning member 120, the axis of the rolling cleaning member 120 is the center of the rolling cleaning member 120, and the height of each position on the scraper bar 114 is higher than the center height of the rolling cleaning member 120, that is, the scraper bar 114 is located in the upper half of the rolling cleaning member 120.

[0206] It is understandable that if the scraper bar 114 is located at the highest point of the rolling cleaning member 120, part of the sewage scraped out by the scraper bar 114 may stay at the highest point of the rolling cleaning member 120 under the action of gravity, or flow in the direction away from the scraper bar 114, and thus cannot reach the water outlet 115 and be discharged; if the height of the scraper bar 114 is lower than the axis height of the rolling cleaning member 120, when the scraper bar 114 scrapes out the sewage and impurities on the mop 121, the impurities gather on the periphery of the lower half of the rolling cleaning member 120. When the rolling cleaning member 120 rotates along the second direction Y, the collected impurities need to bypass most of the rolling cleaning member 120 before they can be discharged from the accommodating cavity 113, resulting in reduced efficiency of the cleaning component 100 in cleaning impurities.

[0207] By setting the height of the scraper 114 to be lower than the highest point of the rolling cleaning member 120 and higher than the axis height of the rolling cleaning member 120, the efficiency of sewage flowing to the outlet 115 under its own gravity can be improved, and the efficiency of the cleaning component 100 in cleaning impurities can be improved.

[0208] In some embodiments, as shown in FIG. 1 , the water outlet 115 is located on an upstream side of the scraping bar 114 along the first direction X.

[0209] During actual implementation, when the rolling cleaning member 120 rotates along the first direction X, the sewage and impurities on the mop 121 are scraped off by the scraping bar 114 and gathered on the upstream side of the scraping bar 114 along the first direction X. Since the water outlet 115 is located on the upstream side of the scraping bar 114 along the first direction X, the sewage can enter the water outlet 115 on the upstream side of the scraping bar 114 along the first direction X after being scraped off by the scraping bar 114 and be discharged from the water outlet 115.

[0210] It can be understood that if the water outlet 115 is located on the downstream side of the scraper bar 114 along the first direction X, it is necessary to provide a through hole on the scraper bar 114 or use other means to allow the sewage to flow to the downstream side of the scraper bar 114 along the first direction X. Since the bottom of the accommodating chamber 113 is an opening, some sewage may enter the water outlet 115 on the downstream side of the scraper bar 114 along the first direction X, and some sewage may flow along the gap between the inner wall of the accommodating chamber 113 and the mop 121 to the opening of the accommodating chamber 113 and drip onto the ground, causing secondary pollution to the ground.

[0211] By arranging the water outlet 115 to be located at the upstream side of the scraping bar 114 along the first direction X, it is possible to facilitate the entry of sewage into the water outlet 115 and reduce the probability of secondary pollution of the ground by the sewage.

[0212] In some embodiments, as shown in FIG. 1 , the lowest point of the upstream side wall of the scraper bar 114 is flush with the wall of the water outlet 115 .

[0213] Among them, the connecting part of the first wiper portion 1141 and the second wiper portion 1142 is flush with the wall surface of the water outlet 115 along the upstream side of the first direction X, and the water outlet 115 is located on the upstream side of the scraper bar 114 along the first direction X, that is, the lowest point of the upstream side wall surface of the scraper bar 114 is flush with the downstream side wall surface of the water outlet 115 along the first direction X.

[0214] During actual implementation, when the rolling cleaning member 120 rotates along the first direction X, the sewage and impurities on the mop 121 are scraped off by the scraper bar 114 and gathered at the lowest point on the upstream side of the scraper bar 114 along the first direction X. Since the lowest point of the upstream side wall of the scraper bar 114 is flush with the wall of the water outlet 115, the impurities and sewage are exactly located at the port of the water outlet 115 when the scraper bar 114 is at the lowest point. At this time, the sewage can directly enter the water outlet 115 and be discharged.

[0215] By setting the lowest point of the upstream side wall of the scraper bar 114 to be flush with the wall of the water outlet 115, after the scraper bar 114 scrapes off the sewage and impurities, the sewage can directly enter the water outlet 115 and be discharged, which can improve the self-cleaning efficiency and self-cleaning effect of the cleaning component 100.

[0216] In some embodiments, as shown in FIG. 2 , the cleaning assembly 100 further includes a first filtering structure 130 . The first filtering structure 130 is installed on the outer periphery of one end of the water outlet 115 facing the accommodating cavity 113 .

[0217] The first filter structure 130 may be a screen, filter cotton or other first filter structures 130 . For example, the first filter structure 130 is a screen, and the mesh size of the screen can be selected according to actual conditions.

[0218] During actual implementation, when the rolling cleaning member 120 rotates along the first direction X, the sewage and impurities on the mop 121 are scraped off by the scraping bar 114 and gathered at the lowest point on the upstream side of the scraping bar 114 along the first direction X. Under the filtering action of the first filtering structure 130, the sewage passes through the first filtering structure 130 and enters the water outlet 115, while the impurities are blocked outside the water outlet 115 by the first filtering structure 130.

[0219] By setting the above-mentioned first filter structure 130, impurities can be prevented from entering the water outlet 115, thereby reducing the probability of impurities accumulating in the water outlet 115 and causing blockage of the water outlet 115. At the same time, blocking the impurities outside can facilitate the subsequent cleaning of impurities that have not been discharged from the accommodating cavity 113, thereby improving the user experience.

[0220] In some embodiments, the inner wall surface of the accommodating cavity 113 may also be provided with a scraper, which may include a plurality of protruding teeth, and the plurality of protruding teeth are spaced apart and distributed along the extension direction of the scraper bar 114, and the scraper may be located upstream of the scraper bar 114 along the first direction X. The scraper may also filter large impurities.

[0221] An embodiment of the present application further provides a main body of a cleaning device, as shown in FIG1 . The main body of the cleaning device includes a base and a cleaning component 100 as described in any one of the above embodiments, and the cleaning component 100 is installed on the base.

[0222] According to the host of the cleaning device provided by the embodiment of the present application, by adopting the cleaning component 100 of any of the above-mentioned embodiments, impurities scraped out and accumulated in the gaps can be automatically discharged, reducing the user's operation steps, and improving the automation and intelligence of the cleaning component 100. At the same time, the mop 121 can be cleaned in real time when the cleaning component 100 cleans the floor without returning to the base station, so as to reduce the probability of the dirt and impurities on the mop 121 causing secondary pollution to the floor, thereby improving the cleaning effect and cleaning efficiency.

[0223] In some embodiments, the main body of the cleaning device further includes a pumping device, which is connected to the water outlet 115 of the cleaning component 100.

[0224] The pumping device may be a centrifugal pump, a jet pump, an air compressor or other types of pumping devices.

[0225] During the actual implementation process, when the rolling cleaning member 120 rotates along the first direction X, the sewage and impurities on the mop 121 are scraped off by the scraping bar 114 and gathered at the lowest point on the upstream side of the scraping bar 114 along the first direction X. When the impurities and sewage are at the lowest point of the scraping bar 114, they are exactly located at the port of the water outlet 115. At this time, the sewage can be pumped into the water outlet 115 and discharged through the pumping device.

[0226] By setting the above-mentioned pumping device, the efficiency of discharging sewage can be improved. At the same time, since the water outlet 115 extends vertically, the probability of sewage entering the water outlet 115 can be increased through active pumping by the pumping device.

[0227] In some embodiments, as shown in FIG. 1 , the mounting frame 110 of the cleaning assembly 100 is provided with a water inlet 116 communicating with the accommodating chamber 113 , and the main body of the cleaning device further includes a water injection device communicating with the water inlet 116 .

[0228] Among them, the water injection device can include a water tank and a water pump. The water pump is connected between the water tank and the water injection port 116. The water tank is used to store clean water, and the water pump is used to drive the clean water in the water tank to flow to the water injection port 116. The water injection device can also be other equipment.

[0229] During the actual implementation process, as shown in Figure 1, when the rolling cleaning member 120 rotates along the first direction X, the water injection device can inject clean water into the accommodating chamber 113 through the water injection port 116, and use the clean water to soak the mop 121, so that the dirt on the mop 121 is dissolved in the clean water and the impurities on the mop 121 float. At this time, the scraping bar 114 can scrape out the dirt dissolved in the clean water and the impurities floating on the surface of the clean water, thereby achieving the purpose of cleaning the mop 121.

[0230] By configuring the water injection device and the water injection port 116 , clean water can be injected into the rolling cleaning member 120 in real time, facilitating the cleaning of the mop 121 and improving the cleaning effect of the mop 121 , thereby improving the cleaning effect of the main unit on the floor.

[0231] In some embodiments, as shown in FIG. 1 , the water inlet 116 is located upstream of the water outlet 115 along the first direction X.

[0232] It can be understood that when the water inlet 116 is located on the upstream side of the water outlet 115 along the first direction X, and the rolling cleaning member 120 rotates along the first direction X, the part of the mop 121 that contacts the ground will first pass through the water inlet 116 and then pass through the water outlet 115. At this time, the water injection device injects water into the accommodating chamber 113 through the water inlet 116, which can soak the dirt and impurities that have just been stained on the mop 121, and then be scraped off by the scraping bar 114 when passing through the water outlet 115, so that the ground is cleaned again in a wet but non-drip state.

[0233] If the water inlet 116 is located on the downstream side of the water outlet 115 along the first direction X, when the rolling cleaning member 120 rotates along the first direction X, the portion of the mop 121 in contact with the ground will first pass through the water outlet 115 and then through the water inlet 116. At this time, the scraping bar 114 directly scrapes the relatively dry mop 121, while dirt and impurities may stick to the mop 121 or be hidden deep in the mop 121, making it difficult for the scraping bar 114 to scrape off the dirt and impurities. The dirt and impurities that are not scraped off pass through the water outlet 115 and then the water inlet 116. Under the infiltration of clean water, the dirt and impurities are dissolved in the clean water or float on the clean water. In this state, the mop 121 cleans the ground again, which is likely to cause secondary pollution to the ground.

[0234] By setting the water inlet 116 to be located on the upstream side of the water outlet 115 along the first direction X, the self-cleaning effect of the rolling cleaning member 120 can be improved, and at the same time, the amount of water in the mop 121 itself when cleaning the floor can be reduced, thereby reducing the probability of the user slipping due to the floor being too wet after cleaning, and improving the cleaning effect of the floor.

[0235] An embodiment of the present application also provides a cleaning device, which includes a base station and a host of the cleaning device as described in any of the above embodiments. The base station is used to dock with the host, and after the sewage is pumped into a box for storing sewage by a pumping device, the host can use the self-cleaning setting of the base station in the base station to discharge the sewage in the box. At the same time, the host can use the driving mechanism in the base station to drive the rolling cleaning member 120 to rotate along the second direction Y, thereby discharging impurities from the base station, and using the self-cleaning setting of the base station to discharge the impurities, thereby achieving complete self-cleaning of the cleaning device, reducing the user's operating steps, and further improving the user's usage experience.

[0236] According to the cleaning device provided by the embodiments of the present application, by adopting the main body of the cleaning device of any of the above-mentioned embodiments, impurities scraped out and accumulated in the gaps can be automatically discharged, reducing the user's operating steps, and improving the automation and intelligence of the cleaning component 100. At the same time, the mop 121 can be cleaned in real time when the cleaning component 100 cleans the ground without returning to the base station, so as to reduce the probability of the dirt and impurities on the mop 121 causing secondary pollution to the ground, improve the cleaning effect and cleaning efficiency, and at the same time achieve complete self-cleaning of the cleaning device, reduce the user's operating steps, and further improve the user's usage experience.

[0237] In some embodiments, when the host enters the base station, the rolling cleaning member 120 of the cleaning assembly 100 of the host rotates along the second direction Y and discharges the scraped garbage into the cleaning tank of the base station.

[0238] When the host is located in the base station, the cleaning tank can be located below the rolling cleaning member 120 .

[0239] During the actual implementation process, after the host completes the cleaning task outside the base station, the host needs to return to the base station to charge. When the host returns to the designated position of the base station, the host controls the rolling cleaning member 120 to rotate along the second direction Y, thereby discharging the impurities in the cleaning component from the bottom to the cleaning tank through the rotation of the rolling cleaning member 120, and then cooperating with the self-cleaning function of the base station to achieve complete self-cleaning of the cleaning equipment.

[0240] Through the above settings, after the host completes the cleaning task and returns to the base station, the garbage and impurities inside the host can be automatically processed, thereby further reducing the user's workload and further improving the user experience.

[0241] In some embodiments, the cleaning device further includes a cleaning device, a dirt collecting device and an air suction channel.

[0242] Among them, the cleaning device is installed in the cleaning tank and is used to clean the garbage in the cleaning tank. The cleaning device can be a scraper, a roller brush or other mechanisms.

[0243] The dirt collecting device is used to collect the cleaned garbage, and the suction channel is connected between the cleaning tank and the dirt collecting device, and is used to suck the garbage in the cleaning tank to the dirt collecting device.

[0244] A suction device may be provided in the air suction channel, and the garbage in the cleaning tank may be sucked into the sewage collecting device through the suction device.

[0245] During the actual implementation process, after the impurities in the host are discharged into the cleaning tank, the cleaning device cleans the garbage in the cleaning tank and scrapes off the garbage impurities adhering to the inner wall of the cleaning tank, so that the garbage in the cleaning tank is gathered in the designated area. Finally, the suction device uses the garbage impurities in the designated area through the suction channel to the sewage collection device, and the self-cleaning of the host and base station can be completed.

[0246] By setting up the above-mentioned cleaning device, air suction channel and dirt collecting device, the garbage in the cleaning tank can be cleaned up, thereby further reducing the user's workload and further improving the user's experience.

[0247] An embodiment of the present application provides a sewage discharge structure 140 , as shown in FIG3 . The sewage discharge structure 140 includes a tank body 141 and a second filtering structure 142 disposed in the tank body 141 .

[0248] The tank body 141 has a sewage tank 141a and a water scraping rib 143 located on one side of the sewage tank 141a. The sewage tank 141a is used to temporarily store sewage, and the sewage flows into the sewage tank 141a along the water scraping rib 143.

[0249] The second filter structure 142 includes at least a first filter component 1421 having a first filter gap 1421a and a second filter component 1422 having a second filter gap 1422a. The gap size of the first filter gap 1421a is smaller than the gap size of the second filter gap 1422a. The first filter component 1421 is arranged in the sewage tank 141a, and at least a filter space 142a having a water absorption area 142a1 is enclosed in the sewage tank 141a through the first filter component 1421. The second filter component 1422 is arranged on the side of the first filter component 1421 away from the water absorption area 142a1, and is located upstream of the first filter component 1421 along the sewage flow direction.

[0250] 3 , 4 and 6 , the second filter assembly 1422 may be disposed within the sewage tank 141 a or outside the sewage tank 141 a .

[0251] Second filter assembly 1422 is positioned within sewage tank 141a. This allows for the temporary storage of lint and debris within tank 141a, facilitating subsequent cleanup. After entering tank 141a, sewage flows through second filter assembly 1422, then through first filter assembly 1421, and into filter space 142a, which has a water absorption zone 142a1. Second filter assembly 1422 filters lint and large debris particles, while first filter assembly 1421 filters lint and smaller debris particles. Sewage is then discharged from water absorption zone 142a1 and exits the sewage tank 141a.

[0252] The second filter structure 142 shown in Figure 3 only has a first filter component 1421 and a second filter component 1422. In other embodiments, the second filter structure 142 can also have one or more other filter components between the first filter component 1421 and the second filter component 1422. For example, the second filter structure 142 may include a third filter component (not shown) having a third filter gap. The third filter component is located between the first filter component 1421 and the second filter component 1422. The gap size of the third filter gap is larger than the filter gap of the first filter gap 1421a and smaller than the gap size of the second filter gap 1422a. The third filter component can filter medium-sized garbage, reduce the filtering pressure of the first filter component 1421, reduce the probability of the first filter component 1421 being blocked by garbage, and further enhance the filtering effect of the second filter structure 142.

[0253] Please refer to Figure 4. An embodiment of the present application also provides a cleaning assembly 100, which includes a rolling cleaning member 120, a sewage pipe 150a, a sewage box 150b and a sewage discharge structure 140 provided in any embodiment of the present application. The sewage discharge structure 140 is arranged on one side of the rolling cleaning member 120, the scraper rib 143 abuts against the rolling cleaning member 120, the water suction port 150a1 of the sewage pipe 150a is arranged in the water suction area 142a1, and the drain port 150a2 of the sewage pipe 150a is connected to the sewage box 150b.

[0254] The sewage on the rolling cleaning member 120 is scraped off by the scraping ribs 143 and flows into the sewage tank 141a along the scraping ribs 143. After the fluff, large particles of garbage and small particles of garbage in the sewage are filtered by the second filtering structure 142, the sewage is sucked into the sewage box 150b through the sewage pipe 150a in the water absorption area 142a1.

[0255] For example, referring to Figure 4, the rolling cleaning member 120 can be a roller mop. In another embodiment, the rolling cleaning member 120 can also be a crawler mop.

[0256] Please refer to Figure 4. The cleaning component 100 can also include a clean water spray head 160, a roller comb 170a and a dirt scraper 170b. The clean water spray hole, the roller comb 170a and the dirt scraper 170b are all arranged on the outside of the rolling cleaning member 120. The clean water spray hole sprays clean water to the rag on the surface of the rolling cleaning member 120 to clean it. The roller comb 170a plate abuts against the rolling cleaning member 120, which can clean large particles of garbage and hair on the rolling cleaning member 120, reduce the filtering pressure of the second filter structure 142, and enhance the filtering effect of the second filter structure 142; the dirt scraper 170b is arranged below the roller comb 170a to prevent the rolling cleaning member 120 from throwing garbage attached to the rolling cleaning member 120 onto other components when the rolling cleaning member 120 rotates.

[0257] Please refer to Figures 5 and 7. An embodiment of the present application further provides a cleaning device, which includes the cleaning component 100 provided by any embodiment of the present application.

[0258] It should be noted that the cleaning component 100 of the embodiment of the present application is not limited to being installed on a cleaning device, and other cleaning devices can also use the cleaning component 100 of the embodiment of the present application, such as a floor scrubber.

[0259] The sewage discharge structure 140 of the embodiment of the present application is provided with a trough body 141 having a sewage trough 141a and a scraper rib 143, and a second filter structure 142 having the trough body 141. The second filter structure 142 includes at least a first filter component 1421 having a first filter gap 1421a and a second filter component 1422 having a second filter gap 1422a. The first filter component 1421 is provided in the sewage trough 141a, and at least the first filter component 1421 encloses a filter space 142a having a water absorption area 142a1 in the sewage trough 141a. The second filter component 1422 is provided in the first filter component 1421. 21 is located on the side away from the water absorption area 142a1 and upstream of the first filter component 1421 along the water flow direction. The sewage flowing into the sewage tank 141a along the scraper rib 143 first passes through the second filter component 1422. The gap size of the first filter gap 1421a is relatively large, which can filter out the fluff and large particles of garbage in the sewage. The sewage then passes through the second filter component 1422. The gap size of the first filter gap 1421a is relatively small, which can filter out the fluff and small particles of garbage in the sewage. The filtered sewage flows into the filter space 142a with the water absorption area 142a1, which can reduce the probability of the sewage pipe 150a being blocked by garbage when extracting sewage.

[0260] It should be noted that the sewage discharge structure 140 of the embodiment of the present application is not limited to being installed in the cleaning component 100 of the cleaning equipment, and other electrical equipment can also use the sewage discharge structure 140 of the embodiment of the present application.

[0261] The gap size of the first filter gap 1421a can be set as needed. For example, the gap size of the first filter gap 1421a can be 0.5mm-1mm. The first filter gap 1421a within this gap size range can not only ensure the flow rate of sewage when flowing through the first filter gap 1421a, but also ensure the filtering effect of the first filter component 1421, and reduce the probability of lint and small particles of garbage passing through the first filter gap 1421a.

[0262] The gap size of the second filter gap 1422a can also be set according to needs. For example, the gap size of the second filter gap 1422a can be 2mm-4mm. The second filter gap 1422a within this gap size range can not only ensure the flow rate of sewage when flowing through the second filter gap 1422a, but also ensure the filtering effect of the second filter component 1422, and reduce the probability of lint and large particles of garbage passing through the second filter gap 1422a.

[0263] In one embodiment, referring to FIG3 , the inner sidewall of the sewage trough 141a and the first filter assembly 1421 can collectively enclose a filter space 142a. In FIG3 , the inner sidewall of the sewage trough 141a on the side opposite the wiper rib 143 and the first filter assembly 1421 collectively enclose the filter space 142a. After being filtered by the first filter assembly 1421, sewage can enter the filter space 142a. Since most of the lint and garbage have been filtered out, the sewage in the filter space 142a can be pumped out of the sewage pipe, reducing the probability of sewage pipe blockage. In another embodiment, the inner sidewall of the sewage trough 141a on another side and the first filter assembly 1421 can collectively enclose the filter space 142a.

[0264] In another embodiment, the filtering space 142a may be enclosed by only the first filtering component 1421 .

[0265] In one embodiment, please refer to Figure 3, a sedimentation tank 142a2 may be provided in the filter space 142a, and the sedimentation tank 142a2 surrounds the circumference of the water absorption area 142a1. There are still some fine garbage particles in the sewage filtered by the first filter component 1421. When the sewage flows through the sedimentation tank 142a2, some of the fine particles can be settled in the sedimentation tank 142a2, which can further reduce the risk of garbage clogging the sewage pipe 150a.

[0266] In one embodiment, referring to Figures 3, 4 and 6, the first filter assembly 1421 may include a plurality of first filter ribs 14211 spaced apart, with a first filter gap 1421a formed between two adjacent first filter ribs 14211. The first filter ribs 14211 have a simple structure, are easy to process and manufacture, and can be integrally formed with the trough body 141.

[0267] In another embodiment, the first filter assembly 1421 may include a filter mesh having a first filter gap 1421 a .

[0268] In one embodiment, referring to Figures 3, 4 and 6, the second filter assembly 1422 may include a plurality of second filter ribs 14221 spaced apart, with a second filter gap 1422a formed between two adjacent second filter ribs 14221. The second filter ribs 14221 have a simple structure, are easy to process and manufacture, and can be integrally formed with the trough body 141.

[0269] In another embodiment, the second filter assembly 1422 may include a filter screen having a second filter gap 1422a.

[0270] In one embodiment, referring to FIG3 , the second filter assembly 1422 can be located on a side of the sewage trough 141a near the wiper rib 143. The sewage trough 141a is divided into a first area 141a1 and a second area 141a2. The first area 141a1 is located between the wiper rib 143 and the second filter assembly 1422, while the second area 141a2 is located on a side of the second filter assembly 1422 facing away from the first area 141a1. The first filter assembly 1421 is disposed within the second area 141a2. Waste filtered by the second filter assembly 1422 can be temporarily stored in the first area 141a1, while waste filtered by the first filter assembly 1421 can be temporarily stored in the second area 141a2, facilitating subsequent waste removal.

[0271] In one embodiment, please refer to Figures 3 and 4. The width of the first filter rib 14211 is smaller than the width of the second filter rib 14221. The width of the second filter rib 14221 is larger, which can reduce the probability of hair and large particles of garbage clogging the second filter gap 1422a and enhance the filtering effect.

[0272] As shown in Figures 8 to 14, the present application provides a cleaning device, which may be a floor scrubber or a cleaning robot, but is not limited in this embodiment of the present application. The cleaning device includes a housing assembly, a mounting frame 110, a sewage discharge structure 140, and a limiting structure.

[0273] The cleaning device is described as being placed on the ground during operation. The housing assembly includes a receiving chamber, within which a drainage structure 140 is located. The chamber has a first opening facing downward, i.e., the first opening faces the ground, through which the drainage structure 140 can fall to the ground. The drainage structure 140 is located within the receiving chamber and includes a pressing portion 141b , which partially passes through and is exposed outside the housing assembly. A limiting structure is provided between the housing assembly and the drainage structure 140 to restrict movement of the drainage structure 140 relative to the housing assembly. Pressing the pressing portion 141b releases the limiting structure.

[0274] The specific action process of the cleaning device of the above embodiment is as follows: the user presses the pressing part 141b toward the accommodating cavity, and the sewage discharge structure 140 moves toward the accommodating cavity. The stroke of the sewage discharge structure 140 is sufficient to release the limiting structure. At this time, the sewage discharge structure 140 will fall from the first opening to the ground under the action of gravity, and then the outer shell assembly can be lifted to remove the sewage discharge structure 140. The user can clean the sewage discharge structure 140. After cleaning the sewage discharge structure 140, the cleaning device can be turned over and the sewage discharge structure 140 can be turned over and installed in the cleaning device. Since the sewage discharge structure 140 is cleaned at this time, even if the sewage discharge structure 140 is turned over, it will not cause secondary pollution to the cleaning device or the ground.

[0275] Specifically, as shown in Figures 8 to 10 and 14, in some embodiments of the present application, the housing assembly includes a housing body 200 and a mounting bracket 110. The accommodating cavity is provided in the housing body 200, and the mounting bracket 110 is installed in the accommodating cavity. The lower portion of the mounting bracket 110 is provided with an accommodating cavity 113, and the accommodating cavity 113 is used to install the roller and the sewage discharge structure 140. The roller is provided with a rolling cleaning member 120. The lower portion of the accommodating cavity 113 is provided with a second opening, and the sewage discharge structure 140 can fall to the ground from the second opening. An avoidance position is provided on the housing body 200, and the avoidance position is connected to the accommodating cavity. The area of ​​the mounting frame 110 corresponding to the avoidance position is the panel housing 118. The panel housing 118 can extend from the avoidance position so that the panel housing 118 is exposed to the outer shell body 200. The panel housing 118 is provided with an avoidance opening, which is connected to the accommodating chamber 113. The sewage discharge structure 140 is located in the accommodating chamber 113. The limiting structure is provided between the mounting frame 110 and the sewage discharge structure 140, and the pressing portion 141b is inserted through the avoidance opening. The user can release the limiting structure by pressing the pressing portion 141b, so that the sewage discharge structure 140 falls from the accommodating chamber 113 to the ground under the action of gravity. Other components can also be installed in the accommodating chamber 113 of the mounting frame 110, such as a roller. The outer shell assembly is assembled by the outer shell body 200 and the mounting frame 110, which can reduce the complexity of the outer shell body 200. At the same time, it is relatively convenient to add other components to the mounting frame 110 and then assemble the entire assembly into the outer shell body 200, thereby reducing the difficulty of assembly. Of course, in some embodiments of the present application, the limiting structure can also be separately provided on the housing assembly or the sewage discharge structure 140 .

[0276] The drainage structure 140 includes a sewage trough 141a for collecting sewage. The rolling cleaning element 120 on the drum is used to clean the floor. The second opening of the accommodating chamber 113 faces the floor, facilitating the entry and exit of the drainage structure 140. The panel housing 118 is a portion of the mounting bracket 110, with the remainder of the mounting bracket 110 located within the housing body 200. Because the pressing portion 141b protrudes from the panel housing 118, the user can directly locate the pressing portion 141b on the outer shell of the cleaning device when it is placed on the floor, making it easier for the user to find and press the pressing portion 141b.

[0277] The specific action process of the cleaning device of the above embodiment is as follows: the user presses the pressing part 141b toward the accommodating cavity, and the sewage discharge structure 140 moves toward the accommodating cavity. The movement stroke of the sewage discharge structure 140 is sufficient to release the limiting structure. At this time, the sewage discharge structure 140 will fall to the ground from the second opening under the action of gravity, and then the outer shell assembly can be lifted to remove the sewage discharge structure 140 from the cleaning device. The user can clean the sewage discharge structure 140. After cleaning the sewage discharge structure 140, the cleaning device can be turned over and the sewage discharge structure 140 can be turned over and installed in the accommodating cavity 113 of the mounting frame 110. Since the sewage discharge structure 140 is cleaned at this time, even if the sewage discharge structure 140 is turned over, it will not cause secondary pollution to the cleaning device or the ground. Of course, after the user is accustomed to disassembling and assembling the sewage structure 140, the user will be more familiar with the position of the limiting structure, and thus can directly lift the cleaning device. Relying on the understanding of the limiting structure, the user can match the sewage structure 140 with the mounting frame 110 from bottom to top, and then install the sewage structure 140 into the accommodating cavity 113. It can be seen that the cleaning device of this embodiment does not need to be turned over when disassembling, thereby reducing the possibility of sewage or garbage remaining in the sewage structure 140 falling onto the cleaning device and the ground when the cleaning device is turned over, thereby reducing the possibility of secondary pollution.

[0278] It should be noted that the embodiments of the shell assembly are not limited to the embodiments of the shell body 200 and the mounting frame 110. In some embodiments of the present application, the shell assembly can only use the shell body 200, that is, the sewage discharge structure 140 is directly installed on the inner wall of the shell body 200, and the pressing portion 141b directly passes through the side wall of the shell body 200 and is exposed on the shell body 200. It is also possible to disassemble the sewage discharge structure 140 without turning over the cleaning equipment.

[0279] As shown in Figure 9, in some embodiments of the present application, the avoidance position is set on the side of the shell body 200, and the panel shell 118 is exposed on the side of the shell body 200 of the cleaning device, and is located at the bottom of the shell body 200 of the cleaning device, so as to facilitate the disassembly and assembly of the sewage discharge structure 140. The avoidance port is set as a notch 1181, and the notch 1181 is located at the lower part of the panel shell 118. The pressing portion 141b is inserted into the notch 1181. Thereby, when the pressing portion 141b is pressed until the limiting structure is released, the sewage discharge structure 140 will fall from the second opening to the ground under the action of gravity. The sewage discharge structure 140 will not be blocked by the notch 1181 during the falling process, so that the sewage discharge structure 140 falls to the ground in a relatively stable posture, reducing the splashing of sewage in the sewage discharge structure 140. The overall structure is simple and practical.

[0280] It should be noted that the panel shell 118 can also be exposed at other positions of the shell body 200, such as the upper end of the side of the shell body 200 or the upper part of the shell body 200, as long as it is convenient for the user to release the limiting structure by pressing the pressing part 141b.

[0281] In addition, the notch 1181 can be replaced by other structures. For example, a through hole can be set on the panel shell 118. When the through hole is large enough to accommodate a finger to pass through, the user can use his fingers to push the pressing part 141b completely out of the through hole, thereby achieving the purpose of using the pressing part 141b to unlock the limiting structure.

[0282] It is understood that the release of the retaining structure by pressing the pressing portion 141b means that the stroke of pressing the pressing portion 141b must be at least greater than the stroke of the retaining structure, that is, along the pressing direction of the pressing portion 141b, the sewage discharge structure 140 moves a minimum distance S to enable the retaining structure to switch from the retaining state to the release state. The height of the portion of the pressing portion 141b passing through the notch 1181 is greater than S, making it smoother when operating the pressing portion 30 to release the retaining structure. As shown in Figure 9, in some embodiments of the present application, the stroke of the retaining structure is generally no more than 2mm. Therefore, the height h of the portion of the pressing portion 141b passing through the notch 1181 can be set to 2mm to 4mm; so that when the user presses the pressing portion 141b until it is flush with the outer surface of the panel housing 118, the retaining structure can be released, which is very convenient and quick, while reducing the possibility of the pressing portion 141b forming a sharp edge on the panel housing 118 and reducing the probability of the pressing portion 141b being accidentally touched and releasing the retaining structure.

[0283] Specifically, the pressing portion 141b can be configured to be in a rectangular parallelepiped shape, a cylindrical shape, a spherical shape, etc., as long as the pressing function can be achieved.

[0284] As shown in FIG10 , in some embodiments of the present application, the limiting structure includes a longitudinal limiting assembly for limiting the vertical movement of the sewage discharge structure 140 relative to the mounting frame 110, and a transverse limiting assembly for limiting the horizontal movement of the sewage discharge structure 140 relative to the mounting frame 110. The longitudinal limiting assembly is used to support the sewage discharge structure 140 to prevent it from falling, and the transverse limiting assembly is used to position the sewage discharge structure 140 in a horizontal plane to prevent the sewage discharge structure 140 from moving in the horizontal direction and causing the longitudinal limiting assembly to fail to support the longitudinal limiting assembly. The transverse limiting assembly and the longitudinal limiting assembly cooperate to limit the position of the sewage discharge structure 140. The longitudinal limiting assembly and the transverse limiting assembly cooperate to form a good support and positioning for the sewage discharge structure 140, ensuring operational stability.

[0285] From a structural point of view, the transverse limit assembly and the longitudinal limit assembly can be set independently or integrated together.

[0286] Specifically, as shown in Figures 10, 11, and 13, in some embodiments of the present application, the transverse limiting assembly includes two positioning grooves 1411 and two first protrusions 119a. The positioning grooves 1411 are provided on the outer sidewall of the sewage discharge structure 140, and the first protrusions 119a are provided on the inner sidewall of the accommodating chamber 113. In this case, the transverse limiting assembly is provided independently, and the accommodating chamber 113 has two parallel inner sidewalls. The two first protrusions 119a are provided on the inner sidewalls of the two parallel accommodating chambers 113. The sewage trough 141a body is provided with two corresponding parallel outer sidewalls. Thus, the sewage trough 141a body can closely fit with the inner sidewalls of the accommodating chamber 113. The first protrusions 119a extend horizontally. When the first protrusions 119a are inserted into the positioning grooves 1411, the horizontal position of the sewage discharge structure 140 can be limited. The overall structure of the transverse limiting assembly is simple and practical.

[0287] Specifically, the accommodating cavity 113 has two parallel inner sidewalls, with a middle section 119b formed on the inner sidewall. The middle section 119b is independently protruding and has a certain degree of elasticity. The first protrusion 119a is provided on the middle section 119b, and the elasticity of the middle section 119b is utilized to enable the first protrusion 119a to enter and exit the positioning groove 1411. Specifically, the positioning groove 1411 can be open outward and downward to facilitate processing.

[0288] It should be noted that the positioning groove 1411 and the first protrusion 119a are not necessarily arranged correspondingly on the sewage discharge structure 140 and the inner wall of the accommodating cavity 113, and they can be adjusted according to actual conditions.

[0289] For example, the positioning groove 1411 can be provided on the inner side wall of the accommodating chamber 113, and the first protrusion 119a can be provided on the sewage discharge structure 140, which can also form a horizontal position limit for the sewage discharge structure 140. In addition, the number of positioning grooves 1411 and first protrusions 119a can also be selected according to actual needs. If the cleaning equipment vibrates significantly during operation, three or more positioning grooves 1411 and three or more first protrusions 119a can be provided to enhance the limiting effect of the lateral limiting assembly on the sewage discharge structure 140 and the mounting frame 110, thereby ensuring the normal operation of the cleaning equipment.

[0290] Specifically, as shown in Figures 10 to 13 , in some embodiments of the present application, a longitudinal stopper assembly is independently provided and includes two support plates 119c and two protrusions 1412. The support plates 119c protrude from the inner sidewalls of the accommodating cavity 113 and are generally horizontal. The protrusions 1412 are provided on the side of the drainage structure 140 away from the pressing portion 141b.

[0291] The two parallel inner side walls on the accommodating chamber 113 are connected with two outwardly expanding inner side walls at the end away from the notch 1181. The distance between the two outwardly expanding inner side walls is greater than the distance between the two parallel inner side walls. Two support plates 119c are arranged at the lower part of the two outwardly expanding inner side walls for supporting the protrusions 1412. Similarly, the two protrusions 1412 on the sewage discharge structure 140 are also arranged at the end away from the pressing portion 141b, and the two protrusions 1412 expand outward relative to the two parallel outer side walls on the sewage tank 141a body.

[0292] When the pressing part 141b and the notch 1181 are assembled, a part of the protrusion 1412 is located on the support plate 119c, and the support plate 119c and the inner side of the panel shell 118 support the sewage discharge structure 140. After the user presses the pressing part 141b into place, the protrusion 1412 follows the sewage discharge structure 140 and moves to the outside of the support plate 119c. At this time, the support plate 119c no longer supports the sewage discharge structure 140. The sewage discharge structure 140 falls under the action of gravity and separates from the cleaning equipment.

[0293] It should be noted that the number of support plates 119c and protrusions 1412 can also be selected according to actual needs. If the weight of the sewage discharge structure 140 is large, three or more support plates 119c and three or more protrusions 1412 can be selected to enhance the supporting effect of the longitudinal limiting component on the sewage discharge structure 140 and ensure the normal operation of the cleaning equipment.

[0294] In order to further improve the vertical support stability of the drainage structure 140, in some embodiments of the present application, the longitudinal limiting assembly further includes two second protrusions 1413 and two positioning holes 1182. As shown in Figures 11 to 13, the positioning holes 1182 are provided on the panel housing 118. The positioning holes 1182 can be provided as through holes to provide better support for the second protrusions 1413. The second protrusions 1413 are provided on the drainage structure 140, and the second protrusions 1413 are provided near the pressing portion 141b. The positioning holes 1182 are provided on the panel housing 118. It can be seen that the positioning holes 1182 cooperate with the second protrusions 1413 to vertically limit and support one end of the drainage structure 140 close to the panel housing 118, and the support plate 119c cooperates with the protrusions 1412 to vertically limit and support the other end of the drainage structure 140. That is, both ends of the drainage structure 140 are limited and supported, so that the drainage structure 140 is well supported in the vertical direction.

[0295] When the pressing part 141b and the notch 1181 are assembled, the second protrusion 1413 is inserted into the positioning hole 1182. The second protrusion 1413 and the positioning hole 1182 cooperate to support the sewage discharge structure 140. After the user presses the pressing part 141b into place, the second protrusion 1413 follows the sewage discharge structure 140 and moves out of the positioning hole 1182. At this time, the second protrusion 1413 no longer supports the sewage discharge structure 140. The sewage discharge structure 140 falls under the action of gravity and separates from the cleaning equipment.

[0296] It should be noted that the positioning hole 1182 and the second protrusion 1413 are not necessarily arranged correspondingly on the panel shell 118 and the sewage discharge structure 140. Other methods can also be used. For example, the positioning hole 1182 can be arranged on the sewage discharge structure 140, and the second protrusion 1413 can be arranged on the inner side of the panel shell 118, which can also achieve support for the sewage discharge structure 140.

[0297] In some embodiments of the present application, from a structural point of view, the lateral limiting assembly and the longitudinal limiting assembly can be integrated together. For example, the longitudinal limiting assembly includes a support plate 119c and a protrusion 1412. The support plate 119c is protruding from the inner wall of the accommodating cavity 113. The support plate 119c is roughly horizontal, and the protrusion 1412 is arranged on the side end of the sewage discharge structure 140 away from the pressing portion 141b. The two parallel inner sidewalls of the accommodating chamber 113 are connected to two outwardly extending inner sidewalls at the ends away from the notch 1181. The distance between the two outwardly extending inner sidewalls is greater than the distance between the two parallel inner sidewalls. Two support plates 119c are provided at the lower portions of the two outwardly extending inner sidewalls to support the protrusions 1412. Similarly, the two protrusions 1412 on the sewage structure 140 are also provided at the ends away from the pressing portion 141b, and the two protrusions 1412 extend outward relative to the two parallel outer sidewalls of the sewage tank 141a. The transverse limiting assembly may include a positioning groove 1411 and a first protrusion 119a. The first protrusion 119a may be provided on the support plate 119c, and the positioning groove 1411 may be provided at the bottom end of the protrusion 1412. Thus, the transverse limiting assembly and the longitudinal limiting assembly may be structurally integrated on the support plate 119c and the protrusion 1412, resulting in a compact structure.

[0298] As shown in FIG11 , in some embodiments of the present application, a filter space 142a is defined in the sewage tank 141a by a filter unit. The filter space 142a is connected to the water inlet pipe of the water pump. The water in the filter space 142a is pumped into the sewage box 150b by the water pump. The sewage box 150b is located above the sewage discharge structure 140. The sewage box 150b can be moved in and out of the avoidance position so that the sewage box 150b can be disassembled and cleaned. The filter unit includes a plurality of first filter components 1421. The first filter components 1421 The first filter components 1421 are arranged in a rectangular shape at intervals. The filter space 142a can be completely surrounded by the first filter components 1421, or the filter space 142a can be surrounded by the inner wall of the sewage tank 141a and the first filter components 1421 to reduce the use of the first filter components 1421. There is a gap between two adjacent first filter components 1421, and the gap can be used for water to flow through. It can intercept some garbage, reduce the amount of garbage entering the filter space 142a, and reduce the occurrence of blockage of the water inlet pipe of the water pump.

[0299] The mounting frame 110 is provided with an avoidance hole 117 corresponding to the filter space 142 a so that the water inlet pipe can enter the filter space 142 a through the avoidance hole 117 to pump water.

[0300] It should be noted that the shape of the filtering space 142a is not limited to the above-mentioned rectangle, and it can also be circular, arched, elliptical, etc.

[0301] As shown in Figures 11 and 14, a preliminary filtration structure can be provided to further intercept garbage. In some embodiments of the present application, a scraping rib 143 is provided at the upper end of the sewage body to scrape water from the rolling cleaning element 120 on the drum. The area below the scraping rib 143 can be considered the water inlet of the sewage trough 141a. A plurality of second filter assemblies 1422 are provided at the water inlet of the sewage trough 141a. The second filter assemblies 1422 are arranged at intervals in a straight line and are evenly distributed at the water inlet of the sewage trough 141a. The gap between two adjacent second filter assemblies 1422 is larger than the gap between two adjacent first filter assemblies 1421. The above-mentioned arrangement of second filter assemblies 1422 constitutes a preliminary filtration structure.

[0302] The sewage scraped off from the rolling cleaning element 120 on the drum first flows through the gap between the second filter components 1422, then flows through the gap between the first filter components 1421, and finally reaches the filter space 142a. Larger garbage will be intercepted by the second filter component 1422, and slightly smaller garbage will be intercepted by the first filter component 1421. The different sizes of garbage are intercepted in a graded manner, thereby reducing the problem of the gap between the first filter components 1421 being blocked by larger garbage, and increasing the frequency of disassembly and cleaning of the sewage tank 141a.

[0303] The shapes of the first filter component 1421 and the second filter component 1422 are not limited and can be cylindrical, sheet-like or other shapes as long as they can intercept garbage.

[0304] Among them, the arrangement of the second filter component 1422 is not limited to a straight-line arrangement, it can also be other arrangements. For example, multiple second filter components 1422 can form an A-shaped arrangement, with the tip of the arrangement facing the wiper rib 143, and the intercepted garbage automatically moves to both ends to ensure the filtering performance of the middle position of the preliminary filter structure.

[0305] In summary, as shown in Figures 8 to 14 , one embodiment of the present application provides a cleaning device, including a housing 200, a mounting bracket 110, a drainage structure 140, and a position limiting structure. The housing 200 is generally rectangular, and square when viewed from above, with smooth corner transitions. A control knob 300 is provided on the upper portion of the housing 200.

[0306] The mounting frame 110 houses a drum, a sewage structure 140, a water spray assembly, a comb plate, and a sewage shield. The comb plate has a serrated lower portion. The water spray assembly includes multiple water spray holes on the drum. The sewage structure 140 is provided with a sewage trough 141a, which houses multiple first filter assemblies 1421 and multiple second filter assemblies 1422 for filtering sewage.

[0307] The outer cover of the drum is provided with a rolling cleaning member 120, and the water spraying assembly sprays clean water toward the rolling cleaning member 120 to clean the rolling cleaning member 120. The dirt shield is installed at the lower part of the mounting frame 110. After cleaning the ground, the rolling cleaning member 120 first passes through the dirt shield. The dirt shield can reduce the occurrence of the situation where the garbage carried by the rolling cleaning member 120 is thrown into the accommodating chamber 113 when the rolling cleaning member 120 rotates. After passing the dirt shield, the rolling cleaning member 120 contacts the comb plate again. The comb plate further intercepts the garbage carried by the rolling cleaning member 120, reducing the amount of garbage entering the next link. The rolling cleaning member 120 After passing through the comb plate, 120 continues to rotate and passes through the water spray assembly. The water spray assembly sprays clean water onto the rolling cleaning member 120 to clean the rolling cleaning member 120. Then the rolling cleaning member 120 continues to rotate to the sewage discharge structure 140. The sewage discharge structure 140 is provided with a wiper rib 143. The wiper rib 143 is arranged parallel to the rolling cleaning member 120. When the rolling cleaning member 120 passes through the wiper rib 143, it will be squeezed by the wiper rib 143, and the squeezed sewage will enter the sewage discharge structure 140. After simple filtration by the sewage discharge structure 140, the sewage is finally pumped into the sewage box 150b for storage.

[0308] The mounting frame 110 is also provided with a panel housing 118, which is exposed on the outer shell body 200. The drainage structure 140 is provided with a pressing portion 141b, which passes through the notch 1181, so that the user can directly operate the pressing portion 141b outside the cleaning device. The limiting structure includes a longitudinal limiting structure and a transverse limiting structure. The transverse limiting structure includes two positioning grooves 1411 and two first protrusions 119a. The positioning grooves 1411 are provided on the outer wall of the drainage structure 140, and the first protrusions 119a are provided on the inner wall of the accommodating cavity 113. The longitudinal limiting structure includes two support plates 119c and two protrusions 1412; the support plate 119c is protruding from the inner wall of the accommodating cavity 113, and the support plate 119c is roughly horizontal. The longitudinal limiting assembly also includes two second protrusions 1413 and two positioning holes 1182. Positioning holes 1182 are provided on the panel housing 118. Positioning holes 1182 can be configured as through holes to provide better support for the second protrusions 1413. Second protrusions 1413 are provided on the drainage structure 140, near the pressing portion 141b, and positioning holes 1182 are provided on the panel housing 118. The drainage structure 140 is provided with multiple first filter assemblies 1421 and multiple second filter assemblies 1422. The first filter assemblies 1421 enclose a filter space 142a for the water pump's inlet pipe to connect. Multiple second filter assemblies 1422 are provided at the water inlet of the sewage trough 141a to perform preliminary filtration of the sewage and intercept larger waste. A relief hole 117 is provided on the mounting frame 110 corresponding to the filter space 142a to pump the filtered sewage from the sewage trough 141a into the sewage box 150b for storage.

[0309] When the cleaning device of the above embodiment is placed normally on the ground, the user can observe the pressing portion 141b. By pressing the pressing portion 141b, the sewage structure 140 will fall to the ground under the action of gravity. The outer shell assembly can be lifted to remove the sewage structure 140 from the cleaning device for cleaning. After cleaning, it can be installed in the mounting frame 110. The sewage structure 140 is clean after cleaning. Regardless of the installation method, it will not cause secondary pollution to the ground or the cleaning device. The limiting structure can form a good limit and support for the sewage structure 140 when the cleaning device is working. The setting of the first filter component 1421 and the second filter component 1422 can intercept some larger garbage, reduce the occurrence of blockage of the water pump's water inlet pipe, reduce the cleaning frequency of the sewage tank 141a, and reduce the burden on the user.

[0310] 15 , a cleaning device is provided in an embodiment of the present application, including a mounting frame 110, a rolling cleaning member 120 and a sewage discharge structure 140. The mounting frame 110 has an accommodating chamber 113 inside, and part of the rolling cleaning member 120 is accommodated in the accommodating chamber 113, and a part of the rolling cleaning member 120 is exposed from the accommodating chamber 113, so that the rolling cleaning member 120 can contact 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 rolling cleaning member 120 is rotatably connected to the mounting frame 110. During the rotation of the rolling cleaning member 120 relative to the mounting frame 110, its outer peripheral surface rubs against the working surface, resulting in the effect of wiping and cleaning the working surface. The rolling cleaning member 120 is mounted on the mounting frame 110 via rotatable components such as a rotating shaft and bearings, and both ends of the rolling cleaning member 120 in the axial direction are supported by the mounting frame 110. The rotation of the rolling cleaning member 120 can be directly driven by a motor that can output rotational power, or it can be indirectly driven by the motor 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 rolling cleaning member 120, an opening 101 is provided at the bottom of the mounting frame 110 for exposing the rolling cleaning member 120. The opening 101 is connected to the accommodating chamber 113. When the cleaning device is in operation, the rolling cleaning member 120 continues to rotate, and the bottom of the rolling cleaning member 120 is kept in stable contact with the working surface to ensure the cleaning effect.

[0311] The drainage structure 140 is connected to the mounting frame 110 and is located on one side of the opening 101. The drainage structure 140 includes a wiper rib 143 and a trough body 141. One end of the wiper rib 143 abuts the outer circumference of the rolling cleaning member 120. During the rotation of the rolling cleaning member 120, the wiper rib 143 and the outer circumference of the rolling cleaning member 120 generate relative motion. The wiper rib 143 can scrape impurities and dirt from the surface of the rolling cleaning member 120 and squeeze the rolling cleaning member 120 to cause the rolling cleaning member 120 to discharge sewage. In addition, at least a portion of the wiper rib 143 defines a sewage inlet 102. The inner cavity of the trough body 141 is connected to the accommodating chamber 113 through the sewage inlet 102. Dirt and sewage discharged from the surface of the rolling cleaning member 120 can enter the trough body 141 through the sewage inlet 102 and be temporarily stored by the trough body 141. The mounting frame 110 is also provided with a water inlet 116, which is connected to the accommodating chamber 113. The water inlet 116 can lead cleaning liquid to the rolling cleaning member 120. The cleaning liquid is not limited to clean water, a solution containing cleaning reagents, etc. The cleaning liquid flowing to the outer surface of the rolling cleaning member 120 can clean the outer peripheral surface of the rolling cleaning member 120 to remove dirt on the outer surface of the rolling cleaning member 120, so that the rolling cleaning member 120 remains in a clean state, and can continuously clean the working surface to avoid the situation where the rolling cleaning member 120 contaminates the working surface for the second time.

[0312] The cleaning equipment has a working state for cleaning the working surface. As shown in Figure 15, when the cleaning equipment is in the working state, the mounting frame 110 moves along the first direction, and at the same time, the rolling cleaning member 120 rotates along the second direction. The rolling cleaning member 120 moves synchronously with the movement of the mounting frame 110, so that the rolling cleaning member 120 can clean the working surfaces at different positions; in addition, along the second direction, the sewage inlet 102 is located in front of the water injection port 116, and the scraper rib 143 is located in front of the sewage inlet 102. Along the first direction, the sewage inlet 102 is located on the rear side of the water injection port.

[0313] On the one hand, with a certain area A on the outer peripheral surface of the rolling cleaning member 120 as a reference, when the rolling cleaning member 120 rotates in the second direction, area A passes through the water inlet 116, the sewage inlet 102 and the wiper rib 143 in sequence. When the cleaning liquid introduced from the water inlet 116 flows to area A, the cleaning liquid cleans area A and produces sewage. As the rolling cleaning member 120 continues to rotate, when area A moves to the wiper rib 143, it is squeezed and scraped by the wiper rib 143, and the sewage and dirt in area A are discharged. The sewage outlet 102 is defined by the scraping rib 143 and the inner wall of the mounting frame 110, and the sewage inlet 102 is located behind the scraping rib 143 in the rotation direction of the rolling cleaning member 120. The sewage and dirt scraped by the scraping rib 143 can be directly discharged into the trough body 141 through the sewage inlet 102. After the A area passes through the scraping rib 143, the sewage and dirt on its surface have been discharged and will no longer cause pollution to 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 to scrape off the sewage on the working surface, so it is more convenient to use. On the other hand, as shown in Figure 15, the rolling cleaning member 120 rotates along the second direction while following the mounting frame 110 to move along the first direction. The portion of the rolling cleaning member 120 exposed from the opening 101 is used to clean the working surface. This portion is defined as a cleaning area. The cleaning area has a tendency to rotate left and at the same time follows the mounting frame 110 to move left. 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 mounting frame 110. The degree of friction between the cleaning area and the working surface can be increased, making the cleaning of the working surface more thorough.

[0314] It should be noted that the first direction is the forward direction of the cleaning equipment. When the cleaning equipment moves forward, the mounting bracket 110 moves in the direction away from the sewage discharge structure 140; the second direction is the rotation direction of the rolling cleaning member 120 when the cleaning equipment moves forward, and the linear velocity of the top position of the rolling cleaning member 120 is away from the first direction, and the linear velocity of the cleaning area is always toward the first direction, that is, when the rolling cleaning member 120 rotates in the second direction, the top position of the rolling cleaning member 120 passes through the sewage discharge structure 140 and the cleaning area in sequence.

[0315] In addition, the sewage inlet 102 can be formed by the wiper rib 143 alone, that is, the wiper rib 143 has a sewage inlet 102, the wiper rib 143 is connected to one side of the trough body 141, and the inner cavity of the trough body 141 is connected to the sewage inlet 102; or the sewage inlet 102 is formed by the wiper rib 143 and the inner wall of the mounting frame 110, which can simplify the structure of the wiper rib 143; or the sewage inlet 102 is formed by the wiper rib 143 and the inner wall of the trough body 141, and the sewage can directly enter the interior of the trough body 141 along the inner wall of the trough body 141, so that the sewage can be more conveniently collected in the trough body 141. The rolling cleaning member 120 includes a rolling brush for cleaning and wiping the working surface, a rolling cleaning member body-shaped rag, a crawler-type rag, etc. Taking the rolling cleaning member 120 including the rolling cleaning member body 122 as an example, the rolling cleaning member body 122 is similar to a cylindrical structure, and the outer surface of the rolling cleaning member body 122 is provided with a liquid absorption layer, which can contact 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 rolling cleaning member body 122 occupies a small space in the accommodating cavity 113, which is conducive to the position and layout of the rolling cleaning member body 122 in the accommodating cavity 113, and the miniaturized design of the cleaning equipment.

[0316] As shown in Figure 16, a driving module 400 is provided in the cleaning equipment. The driving module 400 is connected to the mounting frame 110 and can drive the mounting frame 110 to move along the first direction, so that the cleaning equipment has a walking function; the driving module 400 includes a rotatable roller, the roller is in contact with the working surface, and when the roller rotates, it drives the mounting frame 110 to move along the first direction. 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 in front of the rolling cleaning member 120 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 rolling cleaning member 120 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 rolling cleaning member 120 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.

[0317] It can be understood that the opening 101 is located in front of the wiper rib 143 in the second direction. Therefore, the outer surface of the rolling cleaning member 120 will first pass through the wiper rib 143 to scrape off the dirt and sewage on the surface, and then be exposed to the opening 101. Therefore, the area where the rolling cleaning member 120 contacts the working surface has been cleaned, so that the rolling cleaning member 120 can continue to clean the working surface in a clean state to ensure the cleaning effect.

[0318] As shown in Figure 15, the mounting frame 110 has a rolling cleaning member body comb teeth 170a arranged toward the rolling cleaning member 120, and part of the rolling cleaning member 120 is located between the rolling cleaning member body comb teeth 170a and the wiper rib 143, and the rolling cleaning member body comb teeth 170a is located in front of the wiper rib 143 in the second direction. Therefore, the area after the rolling cleaning member 120 contacts the working surface first passes through the rolling cleaning member body comb teeth 170a, and the rolling cleaning member body comb teeth 170a can scrape off large particles of impurities such as hair attached to the surface of the rolling cleaning member 120, and hair-like impurities can be entangled on the rolling cleaning member body comb teeth 170a. The rolling cleaning member body comb teeth 170a perform preliminary cleaning on the surface of the rolling cleaning member 120 to prevent excessive dirt from entering the trough body 141, thereby extending the cleaning frequency of the trough body 141. The comb teeth 170a of the rolling cleaning member body are configured in a sawtooth shape and extend entirely along the axial direction of the rolling cleaning member 120 , so that the entire circumference of the rolling cleaning member 120 can be preliminarily cleaned by the comb teeth 170a of the rolling cleaning member body.

[0319] In one embodiment, the water inlet 116 is provided above the sewage inlet 102 and is located above the rolling cleaning member 120. Therefore, the cleaning liquid introduced from the water inlet 116 can flow directly downward to the surface of the rolling cleaning member 120 under the action of gravity, cleaning the rolling cleaning member 120. The sewage formed after the rolling cleaning member 120 is cleaned can also flow downward and be discharged into the tank body 141 through the sewage inlet 102. In addition, the sewage inlet 102 is located above the wiper rib 143. The sewage and dirt scraped off the surface of the rolling cleaning member 120 by the wiper rib 143 are intercepted above the wiper rib 143 and directly discharged into the tank body 141 through the sewage inlet 102.

[0320] It should be noted that in this application, the height direction of the cleaning equipment is used as a reference, the top of the cleaning equipment in the height direction is taken as the upper part, and the bottom of the cleaning equipment in the height direction is taken as the lower part. The water inlet 116 is located above the rolling cleaning member body 122, which means that the water inlet 116 is higher than the highest point of the rolling cleaning member 120 to ensure that the cleaning liquid introduced from the water inlet 116 can flow directly toward the rolling cleaning member 120 and clean the rolling cleaning member 120. Specifically, the water injection port 116 is located directly above the rolling cleaning member 120, that is, the water injection port 116 is located directly above the rotation axis of the rolling cleaning member 120, and the cleaning liquid flowing out of the water injection port 116 flows directly downward to the surface of the rolling cleaning member 120, ensuring that the cleaning liquid can fully act on the rolling cleaning member 120, reducing waste; it should be noted that, in view of processing and assembly errors, the water injection port 116 is not strictly limited to be aligned in the vertical direction with the rotation axis of the rolling cleaning member 120, and the water injection port 116 and the rotation axis of the rolling cleaning member 120 are allowed to be misaligned in the vertical direction.

[0321] Alternatively, the water inlet 116 is located directly above the rolling cleaning member 120, and the water inlet 116 is set toward the sewage inlet 102. In this way, the cleaning liquid flowing out of the water inlet 116 can all flow to the side of the rolling cleaning member 120 facing the sewage inlet 102, and finally be discharged into the trough body 141 through the sewage inlet 102, thereby preventing the cleaning liquid from flowing to other areas of the rolling cleaning member 120, causing the cleaning liquid to flow out of the accommodating cavity 113 and contaminating the working surface.

[0322] It is understandable that there are multiple water inlets 116, which are arranged at intervals along the axial direction of the rolling cleaning member 120. The cleaning liquid flowing out of different water inlets 116 can take into account the cleaning of different axial areas of the rolling cleaning member 120, thereby improving the cleaning effect of the rolling cleaning member 120. In addition, a drainage channel is provided in the mounting frame 110, and the drainage channel extends along the axial direction of the rolling cleaning member 120. Each water inlet 116 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 inlets 116. In addition, a water injection head is provided on the inner wall of the mounting frame 110, and the water injection head is provided to protrude toward the rolling cleaning member 120. The water inlet 116 is provided through the water injection head. The provision of the water injection head can make the water inlet 116 close to the surface of the rolling cleaning member 120, thereby improving the cleaning effect of the rolling cleaning member 120.

[0323] A portion of the inner wall of the mounting frame 110 forms a guide wall 103. The top of the scraping rib 143 has a guide surface 14111. The guide wall 103 is located above the guide surface 14111. The guide wall 103 and the guide surface 14111 jointly define the sewage inlet 102. The guide wall 103 and the guide surface 14111 are both inclined downwardly away from the rolling cleaning member 120. The guide wall 103 and the guide surface 14111 guide the sewage and dirt scraped off the rolling cleaning member 120, allowing the sewage and dirt to enter the trough body 141 more smoothly. It should be noted that the downward inclination of the guide wall 103 and the guide surface 14111 means that the guide wall 103 and the guide surface 14111 both have a tendency to extend downward away from the rolling cleaning member 120. Under this premise, the guide wall 103 and the guide surface 14111 can be set as an inclined surface, an arc surface, a curved surface, etc.

[0324] The trough body 141 is connected to the side of the wiper rib 143 facing away from the rolling cleaning member 120 and is located below the guide wall 103. Since the guide wall 103 and the guide surface 14111 both have a tendency to tilt downward away from the rolling cleaning member 120, the sewage flowing down from the surface of the rolling cleaning member 120 or from the accommodating chamber 113 is guided by the guide wall 103 and directed toward the trough body 141. The sewage and dirt scraped off from the surface of the rolling cleaning member 120 by the wiper rib 143 are intercepted at the guide surface 14111 and discharged into the trough body 141 under the guidance of the guide surface 14111.

[0325] Furthermore, one end of the wiper rib 143 abuts the outer surface of the rolling cleaning element 120, and the other end is connected to the top of the trough 141. Therefore, the trough 141 is lower than the wiper rib 143, which can prevent the backflow of sewage and dirt entering the trough 141. In addition, the opening of the sewage inlet 102 is set to gradually decrease in the direction away from the rolling cleaning element 120. On the one hand, this facilitates the discharge of sewage and dirt into the trough 141 through the sewage inlet 102, and on the other hand, it reduces the probability of sewage and dirt in the trough 141 flowing out. The opening of the sewage inlet 102 refers to the distance between the guiding wall 103 and the guide surface 14111.

[0326] In one embodiment, the groove 141 is connected to the side of the wiper rib 143 facing away from the rolling cleaning member 120. The side of the groove 141 facing away from the wiper rib 143 abuts against the mounting frame 110. In this way, the sewage discharge structure 140 is clamped as a whole between the rolling cleaning member 120 and the mounting frame 110. When the sewage discharge structure 140 is installed, its opposite ends are respectively abutted against the rolling cleaning member 120 and the mounting frame 110 to complete the assembly of the sewage discharge structure 140 to the mounting frame 110. When the sewage discharge structure 140 needs to be disassembled, the rolling cleaning member 120 is removed and the sewage discharge structure 140 is pushed toward the accommodating cavity 113 to remove the sewage discharge structure 140. The sewage discharge structure 140 is convenient to assemble and disassemble.

[0327] Furthermore, the wiper rib 143 and the groove body 141 are set as an integral connection structure. The wiper rib 143 and the groove body 141 do not need to be assembled separately. The sewage discharge structure 140 can be directly assembled with the mounting frame 110. The sewage discharge structure 140 and the mounting frame 110 are easy to disassemble and assemble.

[0328] In addition, the wiper rib 143 and the groove body 141 are both provided with corresponding structures capable of limiting the position of the mounting frame 110, so that the connection between the sewage discharge structure 140 and the mounting frame 110 is more stable. Specifically, referring to Figures 17 and 18, the mounting frame 110 includes a first limiting portion 104 and a second limiting portion 105, the wiper rib 143 has a first connecting portion 14112, and the groove body 141 has a second connecting portion 1414. The first limiting portion 104 abuts against the first connecting portion 14112 toward the rolling cleaning member 120, so that the first connecting portion 14112 is abutted by the first limiting portion 104 toward the rolling cleaning member 120, and the second limiting portion 105 abuts against the second connecting portion 1414 toward the rolling cleaning member 120, so that the second connecting portion 1414 is abutted by the second limiting portion The first limiting portion 104 is configured to limit the contact area of ​​the squeegee 143 and the bottom limiting portion 104 is configured to limit the contact area of ​​the squeegee 143. The first limiting portion 104 is configured to limit the contact area of ​​the squeegee 143 and the bottom limiting portion 104 is configured to limit the contact area of ​​the squeegee 143. The second limiting portion 104 is configured to limit the contact area of ​​the squeegee 143 and the bottom limiting portion 104 is configured to limit the contact area of ​​the squeegee 143.

[0329] As shown in FIG20 , the first connecting portion 14112 is disposed on the top of the wiper rib 143 and is located in the middle of the wiper rib 143 in the axial direction of the rolling cleaning member 120 to avoid the guide surface 14111, allowing sewage and dirt to enter the trough body 141 through the guide surface 14111. Referring to FIG17 , the first limiting portion 104 is disposed on the inner wall of the mounting frame 110 and protrudes toward the rolling cleaning member 120. The first limiting portion 104 and the first connecting portion 14112 abut against each other in the first direction. The second connecting portion 1414 can be a sidewall of the trough body 141 on the side facing away from the rolling cleaning member 120. The second limiting portion 105 is located on the side of the second connecting portion 1414 facing away from the rolling cleaning member 120 and abuts against each other in the first direction.

[0330] The mounting bracket 110 further includes a covering portion 106. A first stopper 104 and a second stopper 105 are connected to opposite ends of the covering portion 106 along a first direction. The covering portion 106 is located at the top of the tank 141 and seals the tank 141, isolating the tank 141 from the external environment. The first stopper 104 protrudes relative to the covering portion 106 toward the rolling cleaning member 120 and engages with the first connecting portion 14112. The second stopper 105 protrudes downward relative to the covering portion 106 and engages with the second connecting portion 1414.

[0331] Furthermore, the first limiting portion 104 and the first connecting portion 14112 are mutually limited in the vertical direction, and the second connecting portion 1414 and the second limiting portion 105 are mutually limited in the vertical direction, so that the sewage discharge structure 140 is simultaneously limited in the vertical direction and the first direction by the combination of the mounting frame 110 and the rolling cleaning member 120, and the position of the sewage discharge structure 140 is more stable. The vertical limiting method of the first limiting portion 104 and the first connecting portion 14112, and the vertical limiting method of the second connecting portion 1414 and the second limiting portion 105 are not limited to plugging, snapping, etc.

[0332] For example, the first limiting portion 104 and the first connecting portion 14112 are mutually engaged, and simultaneously realize mutual limitation in the vertical direction and the first direction; or, one of the second limiting portion 105 and the second connecting portion 1414 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 abut against each other in the vertical direction, realizing the vertical limitation of the second limiting portion 105 and the second connecting portion 1414. It is understandable that the second limiting portion 105 and the second connecting portion 1414, which are connected in a plug-in manner, can also limit each other in the axial direction of the rolling cleaning member 120 to prevent the wiper rib 143 from moving in the axial direction of the rolling cleaning member 120; multiple second limiting portions 105 and second connecting portions 1414 can be provided, and are arranged at intervals along the axial direction of the rolling cleaning member 120, so that the sewage discharge structure 140 is limited by the mounting bracket 110 in different areas in the axial direction of the rolling cleaning member 120.

[0333] In addition, referring to Figure 18, the sewage discharge structure 140 is provided with a protrusion 1412 at both ends of the rolling cleaning member 120 in the axial direction, and the interior of the mounting frame 110 is provided with an abutment portion 107 protruding toward the accommodating cavity 113. The protrusion 1412 abuts against the top of the abutment portion 107, and the protrusion 1412 is clamped between the abutment portion 107 and the bottom surface of the sewage discharge box. Both ends of the sewage discharge structure 140 are vertically limited by the mounting frame 110, so that the sewage discharge structure 140 maintains balance in the axial direction of the rolling cleaning member 120, ensuring that the wiper rib 143 is stably abutted against the surface of the rolling cleaning member 120.

[0334] The groove body 141 is further provided with a recessed positioning groove 1411 at the end portion in the axial direction of the rolling cleaning member 120. The mounting frame 110 is provided with a convex rib 108 protruding toward the sewage structure 140 on the inner wall in the axial direction of the rolling cleaning member 120. The convex rib 108 can be snapped into the positioning groove 1411. When the sewage structure 140 is assembled to the mounting frame 110, the sewage structure 140 is pushed in the radial direction of the rolling cleaning member 120, so that the second connecting portion 1414 continuously approaches the second limiting portion 105. When the convex rib 108 is snapped into the positioning groove 1411, the second connecting portion 1414 completes abutment with the second limiting portion 105. The cooperation between the convex rib 108 and the positioning groove 1411 can indicate to the user whether the sewage structure 140 is properly assembled, making the sewage structure 140 highly convenient to install.

[0335] 17 and 19 , the drainage structure 140 is further provided with a handle 1415. The handle 1415 is connected to the side of the trough 141 facing the rolling cleaning member 120. The handle 1415 is provided for a user to grasp and conveniently push the drainage structure 140, thereby facilitating the removal and assembly of the drainage structure 140 to the mounting bracket 110. The handle 1415 is recessed upward relative to the bottom surface of the trough 141, providing space for the user's hand to grasp and preventing interference with the work surface and hindering the movement of the cleaning device.

[0336] 20 and 21 , the cleaning device further includes a sewage box 150b and a sewage pipe 150a. A plurality of first filter components 1421 are arranged at intervals in the tank body 141. The first filter components 1421 protrude upward based on the bottom wall of the tank body 141. The plurality of first filter components 1421 are arranged to form a filter space 142a. The first filter components 1421 can intercept large particles of impurities such as hair outside the filter space 142a. The sewage enters the filter space 142a through the gaps between the first filter components 1421 and is temporarily stored in the filter space 142a. Both ends of the sewage pipe 150a are respectively connected to the sewage box 150b and the filter space 142a. The sewage in the filter space 142a is discharged into the sewage box 150b through the sewage pipe 150a and can be discharged through the sewage box 150b. With the first filter assembly 1421 intercepting large particles of impurities, only sewage is allowed to enter the sewage box 150b through the sewage pipe 150a, thereby reducing the probability of clogging of the sewage pipe 150a and malfunction of the cleaning equipment.

[0337] A dam 1423 is also provided on the bottom wall of the trough body 141, and the first filter component 1421 is connected to the top of the dam 1423; after the dirt enters the trough body 141 through the dirt inlet 102, large particles or impurities with a certain weight are deposited on the bottom wall of the trough body 141 and are blocked by the dam 1423. The dam 1423 and the first filter component 1421 are combined to intercept the impurities, which can further reduce the probability of impurities entering the filter space 142a.

[0338] In addition, a sewage trough 141a is provided in the trough body 141, and the sewage trough 141a is connected to the filter space 142a through the gap between the first filter components 1421. A plurality of spaced second filter components 1422 are provided in the sewage trough 141a. The second filter component 1422 can also intercept large particles of impurities. As sewage and dirt flow in the trough body 141, hair-like impurities can be intercepted and entangled in the second filter component 1422 or the first filter component 1421. The sewage trough 141a provides storage space for large particles of impurities, thereby preventing impurities from accumulating and clogging the gaps between the first filter components 1421, affecting the entry of sewage into the filter space 142a, and can extend the cleaning frequency of the trough body 141.

[0339] It can be understood that the first filter component 1421 has a space for storing and flowing sewage and dirt between it and the wiper rib 143 in the first direction; the sewage trough 141a and the filter space 142a are distributed along the axial direction of the rolling cleaning member 120, and the filter space 142a is closer to the sewage pipe 150a, so that the sewage is concentrated in the area of ​​the trough body 141 close to the sewage pipe 150a, making it convenient for the sewage pipe 150a to guide the sewage into the sewage box 150b.

[0340] The tank body 141 also has an adsorption portion, which is located at the lowest point of the bottom wall of the filter space 142a. That is, the liquid level of the sewage in the filter space 142a is lowest at the adsorption portion. The sewage remaining in the filter space 142a is concentrated in the adsorption portion. One end of the sewage pipe 150a extends to the adsorption portion, which can absorb the sewage remaining in the tank body 141 and discharge it into the sewage box 150b, so that the sewage in the filter space 142a is discharged more thoroughly and the sewage residue in the tank body 141 is reduced.

[0341] It can be understood that part of the bottom wall of the filtering space 142a is recessed downward to form the adsorption portion; or, the adsorption portion is configured as a groove or hole located on the bottom wall of the filtering space 142a.

[0342] It should be noted that the cleaning equipment in the present application 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, and the rolling cleaning part contacts the ground and cleans the ground. After the surface of the rolling cleaning part passes through the scraping ribs, the sewage and dirt on its surface have been discharged and will no longer cause pollution to the working surface. 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 rolling cleaning part relative to the ground is relatively large, which can increase the degree of friction between the ground and make the cleaning of the working surface more thorough.

[0343] An embodiment of the present application provides a water collection box.

[0344] The water collecting box 180 according to an embodiment of the present application will be described below with reference to FIG. 22 to FIG. 34 .

[0345] As shown in Figures 22 to 34, according to the water collecting box 180 for the cleaning device of the embodiment of the present application, the water collecting box 180 is detachably set on the cleaning device 1000, which is convenient for maintenance and cleaning; a water collecting chamber 185 is defined in the water collecting box 180, and the water collecting chamber 185 is used to collect sewage. The water collecting box 180 has a wiper 181 and a scraper 182, and the wiper 181 and the scraper 182 are arranged at intervals so that a collecting port is defined between the wiper 181 and the scraper 182, and the collecting port is connected to the water collecting chamber 185, so that sewage can enter the water collecting chamber 185 through the collecting port, which can improve the collection effect of sewage and prevent the sewage in the cleaning device 1000 from dripping onto the surface to be cleaned, which is beneficial to improving the cleaning effect of the cleaning device 1000 on the surface to be cleaned.

[0346] Among them, the cleaning device 1000 may have a cleaning member, the cleaning member contacts the surface to be cleaned, and the cleaning member moves relative to the surface to be cleaned to clean the surface to be cleaned. For example, the cleaning member may be a rolling cleaning member 120, and the outer side of the rolling cleaning member 120 may have a mop 122, so that the rolling cleaning member 120 can rotate to clean the surface to be cleaned, and the wiper member 181 can press the rolling cleaning member 120 to scrape out the sewage in the rag when the rolling cleaning member 120 rotates, so that the sewage passes through the collection port and flows along the surface of the wiper member 181 to the water collection chamber 185, and the scraper member 182 can press the rolling cleaning member 120 to scrape out the garbage on the surface of the rag when the rolling cleaning member 120 rotates, which can realize real-time cleaning of the cleaning device 1000, thereby preventing the cleaning device 1000 from contaminating the surface to be cleaned and improving the cleaning effect of the surface to be cleaned.

[0347] According to the water collecting box 180 for the cleaning device in the embodiment of the present application, a wiper 181 and a scraper 182 are provided on the water collecting box 180, and the wiper 181 and the scraper 182 respectively press against the cleaning parts in the cleaning device 1000, so that the water collecting box 180 can clean the cleaning device 1000 in real time when the cleaning device 1000 cleans the surface to be cleaned, thereby preventing the cleaning device 1000 from contaminating the surface to be cleaned, improving the cleaning effect of the surface to be cleaned, and improving the user experience.

[0348] In addition, compared with arranging the scraping member 182 and the water collecting box 180 separately, the probability of the scraping member 182 scraping garbage onto the surface to be cleaned can be reduced, and the cleaning effect of the surface to be cleaned can be improved. By removing the water collecting box 180, the garbage can be handled, which is convenient for operation. At the same time, the structure can be simplified to reduce the space occupied inside the cleaning device 1000. On the basis of improving the cleaning effect of the cleaning surface, it is conducive to the miniaturization of the cleaning device 1000.

[0349] As shown in Figure 22, according to some embodiments of the present application, the wiper member 181 can be a wiper plate, so that the sewage can flow along the surface of the wiper plate, thereby guiding the flow of sewage and reducing the probability of sewage dripping onto the surface to be cleaned. The wiper plate can have wiper ribs, which is beneficial to increase the wiping force of the wiper member 181, and is beneficial for the wiper member 181 to scrape out more sewage, which can improve the collection effect of sewage and improve the cleaning effect of the cleaning equipment 1000.

[0350] As shown in Figures 22, 28 and 29, according to some embodiments of the present application, the scraping member 182 can be a comb plate having a plurality of comb teeth 1821, and the plurality of comb teeth 1821 are arranged at intervals in the length direction of the water collecting box 180 (the left and right direction as shown in Figure 29), so that the comb teeth 1821 are in uniform contact with the cleaning parts in the cleaning device 1000, and the contact range between the comb teeth 1821 and the cleaning parts in the cleaning device 1000 can be increased, thereby improving the cleaning effect of the cleaning device 1000.

[0351] As shown in Figure 22, according to some embodiments of the present application, the wiper is located on the upper side of the collection port (the upper side as shown in Figure 22), and the comb plate is arranged on the lower side of the collection port (the lower side as shown in Figure 22). In the direction from front to back, the wiper extends upward at an angle, so that the sewage can flow downward along the lower surface of the wiper into the water collection chamber 185, preventing the sewage from dripping onto the surface to be cleaned, and the comb plate extends upward at an angle, which can increase the contact area between the comb plate and the cleaning parts in the cleaning device 1000, thereby improving the cleaning effect of the cleaning device 1000.

[0352] Among them, the inclination of the wiper blade and the inclination of the comb plate are different. The inclination of the wiper blade is the inclination angle of the extension direction of the wiper blade relative to the horizontal plane, and the inclination of the comb plate is the inclination angle of the extension direction of the comb plate relative to the horizontal plane. Therefore, the inclination direction of the wiper blade and the inclination direction of the comb plate are different, so that the wiper blade and the comb plate press the cleaning parts in the cleaning device 1000 in different directions respectively, which is beneficial to increase the wiping force of the wiper blade, improve the wiping effect on the cleaning device 1000, and help to improve the scraping force of the scraper plate, which can improve the scraping effect on the cleaning device 1000, and then improve the cleaning effect of the cleaning device 1000.

[0353] In some examples, the cleaning member in the cleaning device 1000 can be a rolling cleaning member 120, and the water collecting box 180 can be set on the front side of the rolling cleaning member 120 (the front side as shown in FIG. 22 ), and the water collecting box 180 can also be set on the rear side of the rolling cleaning member 120 (the rear side as shown in FIG. 22 ), and in the rotation direction of the rolling cleaning member 120, the scraping member 181 and the scraping member 182 are arranged in sequence. As shown in FIG. 22 , the water collecting box 180 is set on the front side of the rolling cleaning member 120. Taking the clockwise rotation of the rolling cleaning member 120 as an example, the wiper member 181 is located above the scraper member 182. If the rolling cleaning member 120 rotates counterclockwise, the wiper member 181 is located below the scraper member 182. In addition, if the water collecting box 180 is arranged on the rear side of the rolling cleaning member 120, taking the counterclockwise rotation of the rolling cleaning member 120 as an example, the wiper member 181 is located above the scraper member 182. If the rolling cleaning member 120 rotates clockwise, the wiper member 181 is located below the scraper member 182.

[0354] As shown in Figures 28 and 29, according to some embodiments of the present application, the water collecting box 180 also has a connecting port 1811, which is connected to the water collecting chamber 185. The cleaning equipment 1000 is provided with a sewage suction pipe 1112, which can be extended into the water collecting box 180 through the connecting port 1811, so that the sewage suction pipe 1112 is connected to the water collecting chamber 185, so that the sewage suction pipe 1112 can suck the sewage collected by the water collecting box 180, which can prevent the sewage in the water collecting box 180 from overflowing, which is beneficial to extend the maintenance cycle of the water collecting box 180 and facilitate maintenance.

[0355] As shown in Figures 28, 29 and 31, in some examples, a portion of the bottom of the water collecting chamber 185 is recessed downward to form a water collecting groove 1851, so that the sewage in the water collecting chamber 185 can flow into the water collecting groove 1851. The water collecting groove 1851 is located below the connecting port 1811 (as shown below in Figure 31), so that the sewage pipe 1112 can extend into the water collecting groove 1851, which is beneficial to improving the water pumping effect of the sewage pipe 1112 and reducing the probability of sewage remaining in the water collecting box 180.

[0356] Moreover, the sewage suction pipe 1112 can be spaced apart from the bottom wall of the water collecting groove 1851, which can reserve a space margin for the installation of the water collecting box 180, preventing the lower end of the sewage suction pipe 1112 from pressing against the bottom wall of the water collecting groove 1851, thereby reducing the probability of damage to the sewage suction pipe 1112 and the probability of damage to the water collecting box 180, and at the same time preventing the bottom wall of the water collecting groove 1851 from blocking the sewage suction pipe 1112, which is beneficial to improving the sewage suction effect.

[0357] As shown in Figure 28, in some examples, the water collection box 180 also includes: a filter element 183, which is arranged in the water collection chamber 185, and the filter element 183 can be arranged on the periphery of the water collection groove 1851, so that the sewage in the water collection chamber 185 can fully flow through the filter element 183 before flowing into the water collection groove 1851, thereby improving the filtering effect of the sewage.

[0358] As shown in Figure 28, in some examples, the filter element 183 includes multiple filter columns 1831, and a water gap is formed between two adjacent filter columns 1831. The water gap is used to circulate sewage, and the filter column 1831 can block debris in the sewage to achieve sewage filtration. By adjusting the position of the filter column 1831, the water gap between the two adjacent filter columns 1831 can be changed. For example, by narrowing the water gap, it is beneficial to achieve the filtration of smaller debris in the sewage, which can improve the filtration effect of sewage.

[0359] In some examples, the filter element 183 can be a filter mesh, which has good filtering effect, low cost, and is easy to assemble.

[0360] As shown in Figures 22 to 34, the cleaning device 1000 according to the embodiment of the present application includes a water collecting box 180. By adopting the above-mentioned water collecting box 180, the water collecting box 180 can clean the cleaning device 1000 in real time when the cleaning device 1000 cleans the surface to be cleaned, thereby preventing the cleaning device 1000 from contaminating the surface to be cleaned, improving the cleaning effect of the surface to be cleaned, and improving the user experience.

[0361] As shown in Figures 27 and 28, according to some embodiments of the present application, the cleaning device 1000 also includes: a base, a mounting frame 110 and a rolling cleaning member 120, the mounting frame 110 is connected to the base, the mounting frame 110 defines a accommodating cavity 113 with one side open, the rolling cleaning member 120 can be installed in the accommodating cavity 113, and the rolling cleaning member 120 is rotatably connected to the mounting frame 110, so that the rolling cleaning member 120 contacts the surface to be cleaned, and the rolling cleaning member 120 rotates relative to the surface to be cleaned, so that the surface to be cleaned can be cleaned.

[0362] The water collecting box 180 is detachably connected to the mounting frame 110, which is convenient for loading and unloading, replacement, and maintenance. After the user removes the water collecting box 180, the user can pour out the debris filtered out by the filter element 183 in the water collecting box 180, and the user can clean the garbage on the water collecting box 180 for easy cleaning.

[0363] As shown in Figures 28 and 30, in some examples, the water collecting box 180 is provided with a connecting piece 184, and the mounting frame 110 is provided with a matching piece 1111. The connecting piece 184 and the matching piece 1111 are snap-fitted to realize the installation of the water collecting box 180, wherein the connecting piece 184 can be a snap-fitting protrusion, and the matching piece 1111 can be a snap-fitting slot. The snap-fitting protrusion and the snap-fitting slot are snap-fitted to realize the connection between the water collecting box 180 and the mounting frame 110, with good connection effect and easy loading and unloading. Alternatively, the connecting piece 184 can be a snap-fitting slot, and the matching piece 1111 can be a snap-fitting protrusion.

[0364] It can be understood that the number of connecting parts 184 can be multiple, and the multiple connecting parts 184 are arranged at intervals along the extension direction of the water collection box 180 (the left and right direction as shown in Figure 30). The number of matching parts 1111 can be multiple, and the multiple matching parts 1111 correspond one-to-one to the multiple connecting parts 184, which can improve the connection effect between the water collection box 180 and the mounting frame 110.

[0365] In some examples, the mounting frame 110 may have an avoidance space, which is used to accommodate the water collecting box 180, which is beneficial to the installation of the water collecting box 180, and the avoidance space is connected to the accommodating chamber 113, which is beneficial for the wiper 181 and the scraper 182 to press the rolling cleaning member 120 respectively, so as to clean the rolling cleaning member 120, wherein the avoidance space can be located at the front side of the accommodating chamber 113. Taking Figure 22 as an example, the water collecting box 180 can clean the rolling cleaning member 120 and collect sewage when the rolling cleaning member 120 rotates clockwise; of course, the avoidance space can also be located at the rear side of the accommodating chamber 113, and the water collecting box 180 can clean the rolling cleaning member 120 and collect sewage when the rolling cleaning member 120 rotates counterclockwise.

[0366] As shown in Figure 29, in some examples, in the extension direction of the rolling cleaning member 120 (the left and right direction as shown in Figure 29), the rolling cleaning member 120 corresponds to at least a portion of the water collecting box 180, that is, the rolling cleaning member 120 mainly corresponds to a portion of the water collecting chamber 185 away from the water collecting groove 1851, so that the sewage can fully flow through the filter element 183, which can reduce the probability of sewage directly flowing into the water collecting groove 1851 and being sucked by the sewage suction pipe 1112, thereby improving the filtering effect of the sewage.

[0367] It can be understood that the water collection groove 1851 can be set at the end of the water collection chamber 185 (the left end or the right end as shown in Figure 29). Based on improving the filtering effect of sewage, there is no need to separately design a rolling cleaning part 120, which can save product design costs.

[0368] In some examples, the cleaning device 1000 also includes: a clean water tank, which is arranged on the base, and the mounting frame 110 is provided with a clean water spray head 160, which is connected to the clean water tank, and the clean water spray head 160 is used to spray clean water to the rolling cleaning member 120, and then when the wiper 181 scrapes out the dirty water on the rolling cleaning member 120, the clean water spray head 160 can spray clean water to the rolling cleaning member 120 in real time. On the basis of improving the cleaning effect of the rolling cleaning member 120 on the surface to be cleaned, the rolling cleaning member 120 can be cleaned in real time, and the rolling cleaning member 120 can be prevented from contaminating the surface to be cleaned after cleaning the surface to be cleaned, thereby improving the cleaning effect of the surface to be cleaned.

[0369] In some examples, the cleaning device 1000 also includes: a pump body, the mounting frame 110 has a sewage suction pipe 1112, the sewage suction pipe 1112 can be extended into the water collection chamber 185, and the pump body is connected to the sewage suction pipe 1112. The pump body can pump out the sewage in the water collection chamber 185 through the sewage suction pipe 1112 to prevent the sewage in the water collection box 180 from overflowing, which is beneficial to reduce the maintenance frequency of the water collection box 180.

[0370] In the present application, the surface to be cleaned can be indoor floors, floor tiles or carpets, etc. The cleaning device 1000 can be built into a sweeping machine. The sweeping machine is generally provided with an environmental monitoring device to facilitate the rotation of the rolling cleaning member 120 in the cleaning device 1000 according to environmental changes, which can improve the intelligence of the sweeping machine. Alternatively, the user can operate on a smart terminal such as a mobile phone or a remote control, and remotely control the rotation of the rolling cleaning member 120 through wireless transmission signals such as infrared, Bluetooth or local area network, which is convenient for operation; of course, the sweeping machine can be provided with an operation panel, and the user directly controls the rotation of the rolling cleaning member 120 through the operation panel.

[0371] Among them, when the rolling cleaning member 120 is not rotating, the wiper member 181 and the scraper member 182 of the water collecting box 180 respectively press against the rolling cleaning member 120, and then when the rolling cleaning member 120 rotates, the water collecting box 180 can clean the rolling cleaning member 120 in real time and collect sewage; in addition, the mounting frame 110 and the rolling cleaning member 120 can be raised and lowered relative to the surface to be cleaned, and when the mounting frame 110 and the rolling cleaning member 120 are raised and lowered, the wiper member 181 and the scraper member 182 can always press against the rolling cleaning member 120.

[0372] In some examples, the rolling cleaning member 120 may be a cleaning member-type mop (as shown in FIG. 24 ) or a crawler-type mop (not shown in the figure), etc.

[0373] In some examples, the cleaning device 1000 can be built into a sweeper. The cleaning device 1000 can also be built into a cleaning robot, a floor scrubber, or a road sweeper, which can expand the scope of application of the cleaning device 1000.

[0374] The following describes a specific embodiment of the present application with reference to Figures 22 to 34. The cleaning equipment 1000 includes a mounting frame 110 and a rolling cleaning member 120. The mounting frame 110 has a accommodating cavity 113 and an avoidance space.
