Description

Technical Field

[0001] The present invention relates to the field of cleaning robots, and in particular to a cleaning robot and a cleaning system. Background Art

[0002] Cleaning robots, such as scrubbers, sweepers, and sweep-and-mop robots, are machines that assist users with cleaning tasks. To achieve better cleaning results, cleaning robots are equipped with a sewage tank, which connects to the robot's wiper element to collect dirt. Because the sewage tank is detachable, the water inlet of the sewage tank is susceptible to collision with the wiper element during installation, causing wear and tear, which can lead to sewage leakage. Summary of the Invention

[0003] The invention provides a cleaning robot and a cleaning system.

[0004] The cleaning robot of the embodiment of the present application includes a body, a wiper member and a sewage tank. The wiper member is movably arranged relative to the body. The wiper member includes a drainage part, which is formed with a drainage outlet. The sewage tank is detachably connected to the body. The sewage tank is formed with a flow channel. The sewage tank includes a surrounding wall and a first protrusion arranged on one side of the surrounding wall. The surrounding wall is located at one end of the flow channel. The first protrusion protrudes from the surface of the surrounding wall toward the body. During the process of installing the sewage tank to the body, the first protrusion abuts against the wiper member to push the wiper member to move relative to the body and make the drainage part bear on the surrounding wall.

[0005] In the cleaning robot of the embodiment of the present application, during the process of installing the sewage tank to the body, the wiper member abuts against the first protrusion of the sewage tank so that the wiper member can be accurately matched with the sewage tank, thereby reducing the collision between the drainage part of the wiper member and the wall of the sewage tank during the installation process, thereby reducing the wear of the wiper member and the sewage tank and improving the service life of the cleaning robot.

[0006] In some embodiments, the wiper element includes a second protrusion provided on the drainage portion, the second protrusion protruding from the edge of the drainage port, and when the sewage tank is installed to the body, the first protrusion abuts against the second protrusion to push the wiper element to move relative to the body.

[0007] In this way, the second protrusion of the wiper element abuts against the first protrusion of the sewage tank so that the wiper element can be accurately matched with the sewage tank, reducing the collision between the drainage part of the wiper element and the wall of the sewage tank during the installation process, thereby reducing the wear of the wiper element and the sewage tank and increasing the service life of the cleaning robot.

[0008] In some embodiments, the second protrusion includes a first guide surface facing the sewage tank. When the sewage tank is installed on the body, the first guide surface contacts the first protrusion to guide the wiper element to move relative to the body, thereby making the drainage portion rest against the surrounding wall.

[0009] In this way, the first protrusion moves along the first guide surface to adjust the relative position of the wiper and the sewage tank, so that the drainage part can be against the surrounding wall, while reducing the wear of the drainage part and the surrounding wall during installation, thereby increasing the service life of the cleaning robot.

[0010] In some embodiments, the first guide surface extends from the bottom of the first guide surface in a direction away from the body relative to the height direction of the cleaning robot.

[0011] In this way, when the first protrusion moves along the first guide surface from the top to the bottom of the first guide surface, the sewage tank and the machine body are brought closer, so that the drainage part and the surrounding wall are brought closer.

[0012] In some embodiments, the first protrusion includes a second guide surface facing away from the body. During the disassembly of the sewage tank and the body, the second guide surface contacts the second protrusion to guide the wiper to move relative to the body, thereby separating the drainage portion from the surrounding wall.

[0013] In this way, the second protrusion moves along the second guide surface to adjust the relative position of the wiper and the sewage tank, so that the drainage part can be separated from the surrounding wall, while reducing the wear of the drainage part and the surrounding wall during installation, thereby increasing the service life of the cleaning robot.

[0014] In some embodiments, the second guide surface extends from the bottom of the second guide surface toward the body relative to the height direction of the cleaning robot.

[0015] In this way, when the second protrusion moves along the second guide surface from the bottom to the top of the second guide surface, the sewage tank is separated from the machine body, so that the drainage part is separated from the surrounding wall.

[0016] In certain embodiments, the sewage tank includes a tank cover and a sealing member disposed on the tank cover, wherein the tank cover forms a flow channel, and the sealing member forms at least a portion of a surrounding wall.

[0017] In this way, the seal can prevent sewage from overflowing from the flow channel, reduce the risk of sewage contaminating the sewage tank and the ground, and improve the cleaning efficiency of the cleaning robot.

[0018] In some embodiments, the surrounding wall includes a top surface, and along the width direction of the flow channel, the top surface is concave from both sides to the middle position to form a concave portion, and the drainage portion rests on the top surface and fits with the concave portion.

[0019] In this way, the drainage portion is engaged with the recessed portion so that the sewage from the wiper element can flow from the drainage portion into the flow channel, thereby reducing the risk of sewage leakage.

[0020] In some embodiments, the cleaning robot also includes a cleaning part, the wiper part includes a main body and a scraper bar formed on the main body, the scraper bar is in conflict with the cleaning part, the drainage part is connected to the main body, the scraper bar and the main body together form a water guide space, the drainage part forms a drainage channel connected to the water guide space, and the drainage channel is connected to the flow channel.

[0021] In this way, the scraping bar and the cleaning piece can scrape off the stains on the cleaning piece, reducing the risk of stains contaminating the ground. The water guide space is connected to the flow channel through the drainage channel, so that the sewage in the water guide space can flow from the drainage channel through the flow channel to the sewage tank. The position of the flow channel is higher, which can reduce the risk of sewage leakage.

[0022] In some embodiments, the cleaning robot includes a bracket, the cleaning element and the wiper element are both mounted on the bracket, and the bracket is detachably connected to the body.

[0023] In this way, the cleaning element and the wiper element can be removed from the machine body together with the bracket for easy cleaning and convenient operation.

[0024] The cleaning system according to the embodiment of the present application includes a base station and a cleaning robot, and the cleaning robot is in contact with the base station.

[0025] In this way, the base station can provide a storage space for the cleaning robot and charge the cleaning robot.

[0058] See also Figure 1-Figure 5 The cleaning robot 100 of the embodiment of the present application includes a body 10, a sewage tank 30, a cleaning member 13 and a wiper member 50. The sewage tank 30 and the cleaning member 13 are both installed on the body 10. The cleaning member 13 is located on one side of the sewage tank 30. The wiper member 50 is in conflict with the cleaning member 13 and forms a water guide space 51 and a drainage channel 52 connected to the water guide space 51. The drainage channel 52 is connected to the sewage tank 30. The water guide space 51 and the drainage channel 52 jointly guide the sewage scraped from the cleaning member 13 by the wiper member 50 to the sewage tank 30 under the action of gravity.

[0059] The cleaning robot 100 of the embodiment of the present application collects sewage into the sewage tank 30 under the action of gravity through the wiper 50 without the aid of an external power component, so that the cleaning robot 100 has a simple structure and low cost.

[0060] Specifically, the body 10 can walk on the working surface, and the cleaning robot 100 can be a floor washing robot, a floor sweeping robot, a sweeping and mopping robot, etc. The cleaning working surface can be a floor or carpet of any material, such as a wooden floor, a tile floor, etc. Figure 1 and Figure 2 In some embodiments, the body 10 includes a sensor device 11, a control unit, and a drive wheel 12. The sensor device 11 is used to monitor the surrounding environment, and the control unit is used for accurate distance measurement and active obstacle avoidance, as well as controlling the movement trajectory of the drive wheel 12. The sensor device 11 can be a collision sensor, a proximity sensor, a visual sensor, etc.

[0061] When the forward direction of the cleaning robot 100 is set to the front, the driving wheel 12 is arranged behind the cleaning part 13. The cleaning part 13 can clean the dirt, water stains, etc. on the ground in front of the driving wheel 12 to prevent dust and water stains from affecting the friction between the driving wheel 12 and the ground, thereby protecting the driving wheel 12 and improving the movement ability of the body 10.

[0062] The sewage tank 30 is used to store dirt produced by the cleaning element 13 after cleaning the floor. The dirt may include sewage, hair, and particulate matter. The cleaning element 13 may include a rag, a roller brush 131, a drum, etc., and is capable of wiping or cleaning the floor while the machine body 10 is in motion. The wiper element 50 scrapes dirt off the cleaning element 13 while it is in operation, directing the dirt into the water guide space 51 through the drainage channel 52 to the sewage tank 30. It also removes any entangled material on the cleaning element 13, preventing it from remaining on the cleaning element 13 and affecting its cleaning effectiveness.

[0063] See also Figure 1 and Figure 6 In some embodiments, the cleaning robot 100 includes a clean water tank 20 , which is detachably mounted on the body 10 , and a sewage tank 30 detachably mounted on the bottom of the clean water tank 20 .

[0064] In this way, the clean water tank 20 and the sewage tank 30 can be disassembled and assembled as a whole relative to the body 10, making the clean water tank 20 and the sewage tank 30 easy to maintain. In addition, the sewage tank 30 is detachably connected to the clean water tank 20, so that the sewage tank 30 can be maintained separately, thereby improving the convenience of maintenance of the cleaning robot 100.

[0065] Specifically, the clean water tank 20 and the dirty water tank 30 form part of the circumferential contour of the cleaning robot 100. The cleaning element 13 is disposed at the bottom of the body 10, and is located on the side facing the dirty water tank 30. The clean water tank 20 is used to store cleaning liquids such as clean water and detergent. The clean water tank 20 is configured to provide the cleaning liquid to the cleaning element 13 to improve the decontamination ability of the cleaning element 13 and further improve the working efficiency of the cleaning robot 100.

[0066] See also Figure 2 In some embodiments, the cleaning member 13 includes a roller brush 131 , and the wiper member 50 is located on one radial side of the roller brush 131 . The wiper member 50 scrapes off dirt on the roller brush 131 during the rotation of the roller brush 131 .

[0067] In this way, the wiper member 50 can scrape off the dirt in the radial direction of the roller brush 131 by simply rotating the roller brush 131 , which is easy to operate.

[0068] Specifically, the wiper member 50 may contact the roller brush 131 , so that the sewage on the roller brush 131 flows onto the wiper member 50 along the radial direction of the roller brush 131 .

[0069] See also Figure 2 In some embodiments, the drainage channel 52 is inclined downwardly toward the sewage tank 30 .

[0070] In this way, the sewage can flow to the sewage tank 30 under the action of gravity without the aid of an external power component, so that the cleaning robot 100 has a simple structure and less stains remain on the wiper 50, reducing the growth of microorganisms such as bacteria.

[0071] Specifically, the drainage channel 52 connects the water guide space 51 and the sewage tank 30 . The height of the water guide space 51 from the ground is higher than the height of the sewage tank 30 from the ground, so that sewage can flow from the high water guide space 51 to the low sewage tank 30 through the drainage channel 52 .

[0072] See also Figure 2 and Figure 5 In some embodiments, the wiper member 50 includes a main body 53 and a scraper strip 54 formed on the main body 53 . The scraper strip 54 and the main body 53 together form a water guide space 51 . The scraper strip 54 contacts the cleaning member 13 .

[0073] In this way, the scraping bar 54 can scrape off the dirt on the roller brush 131 and guide the dirt to the sewage tank 30 through the water guiding space 51 .

[0074] Specifically, the main body 53 may be in the shape of a sheet, and the cross-section of the main body 53 may be arcuate. The scraper bar 54 is configured to scrape the sewage and solid particles off the cleaning element 13. The scraper bar 54 may be arranged at an angle relative to the main body 53 so that the scraper bar 54 can smoothly flow the sewage along the inclined surface toward the sewage tank 30, thereby reducing the sewage flow rate and preventing the sewage from splashing or overflowing. The water guide space 51 is configured to receive the sewage scraped off by the scraper bar 54 and, under the action of gravity, direct the sewage into the drainage channel 52.

[0075] See also Figure 5 、 Figure 7 and Figure 8 In some embodiments, the wiper member 50 includes a drainage portion 55 connected to the main body 53 . The drainage portion 55 protrudes from the edge of the main body 53 and forms a drainage channel 52 . The drainage portion 55 is connected to the sewage tank 30 .

[0076] In this way, the wiper member 50 is more easily connected to the sewage tank 30 through the drainage portion 55 , so that the sewage in the water guide space 51 can flow to the sewage tank 30 through the drainage channel 52 , reducing the risk of sewage leakage.

[0077] Specifically, one end of the drainage portion 55 is connected to the water guide space 51 , and the other end is connected to the sewage tank 30 . The drainage channel 52 can be a closed circular channel or an open arc-shaped channel.

[0078] See also Figure 7-10In some embodiments, the sewage tank 30 includes a box body 31, the box body 31 includes a main body 314 and a box cover 315 connected to the main body 314, the main body 314 forms a accommodating cavity 3144, the box cover 315 forms a flow channel 3151 connected to the accommodating cavity 3144, the drainage portion 55 extends to the flow channel 3151, and the drainage channel 52 is connected to the flow channel 3151.

[0079] In this way, the sewage can flow from the drainage channel 52 to the sewage tank 30 through the flow channel 3151 on the box cover 23. The position of the flow channel 3151 is relatively high, which can fully utilize the volume of the accommodating cavity 3144 of the main body 314 and reduce the risk of sewage overflowing from the flow channel 3151.

[0080] Specifically, the accommodating cavity 3144 is used to accommodate stains in the sewage tank 30. The box cover 315 can be connected to the main body 314 by a snap-fitting manner. An opening 3152 is provided on the upper surface of the main body 314. One end of the flow channel 3151 is connected to the opening 3152, and the other end is close to the edge of the box cover 315 and connected to the water outlet of the drainage channel 52. Sewage can flow from the drainage channel 52 to the flow channel 3151, and then flow into the accommodating cavity 3144 through the opening 3152.

[0081] See also Figure 10 In some embodiments, a sealing strip 39 is provided at the edge of the flow channel 3151 close to the wiper element 50 , and the drainage portion 55 abuts against the sealing strip 39 and is tightly connected to the sealing strip 39 .

[0082] In this way, the sealing strip 39 can prevent sewage from overflowing from the flow channel 3151 , thereby reducing the risk of sewage contaminating the sewage tank 30 and the ground, and improving the cleaning efficiency of the cleaning robot 100 .

[0083] Specifically, the sealing strip 39 can be made of rubber material. The sealing strip 39 is arranged along the circumferential contour of the box cover 315 . One end of the sealing strip 39 is connected to the box cover 315 , and the other end is connected to the body 314 .

[0084] See also Figure 5 In some embodiments, the wiper 50 includes a combing structure 56 formed on the main body 53 , and the combing structure 56 is located on the side of the scraper bar 54 away from the water guide space 51 , and the combing structure 56 is used to comb and collect entanglements on the cleaning element 13 .

[0085] In this way, the entangled materials on the cleaning member 13 are combed off by the combing structure 56 , reducing the risk of the entangled materials coming into contact with the ground again and contaminating the ground, thereby improving the cleaning effect of the cleaning robot 100 .

[0086] See also Figure 5 and Figure 11In some embodiments, the combing structure 56 includes a plurality of protrusions 561 , which are arranged from one side to the other side in the length direction of the main body 53 , and the protrusions 561 are used to be at least partially inserted into the cleaning member 13 of the cleaning robot 100 .

[0087] In this way, the protrusions 561 can comb out the entangled materials on the cleaning member 13 to prevent the entangled materials from remaining on the cleaning member 13 and affecting the cleaning effect of the cleaning member 13 .

[0088] Specifically, the protrusions 561 can be arranged in a straight line along the length direction of the main body 53, or can be arranged in an arc along the length direction of the scraper strip 54. The size and spacing of the protrusions 561 can be set according to actual needs.

[0089] See also Figure 5 and Figure 13 In some embodiments, a plurality of protrusions 561 are arranged along the extension direction of the scraper strip 54 , and the distribution of the protrusions 561 is V-shaped. The protrusions 561 form one or more rows along the length direction of the main body 53 , and the protrusions 561 are arranged in at least one row at the position corresponding to the drainage channel 52 .

[0090] In this way, at least one row of protrusions 561 can comb the cleaning member 13 multiple times, reducing the possibility of entanglements remaining on the cleaning member 13, thereby improving the combing effect of the wiper member 50.

[0091] Specifically, the protrusions 561 are located on the side of the scraper strip 54 facing away from the water-conducting space 51. Within a row of protrusions 561, the distance between two adjacent protrusions 561 ranges from 5 to 7 mm. Within two adjacent rows of protrusions 561, the distance between two adjacent protrusions 561 in different rows ranges from 3 to 5 mm. When the protrusions 561 meet this spacing range, the protrusions 561 can comb away entangled material from the cleaning element 13 and collect it within the space formed by two adjacent protrusions 561. This prevents the entangled material from falling, resulting in a more effective combing effect.

[0092] See also Figure 11 In some embodiments, the cleaning member 13 includes a roller brush 131 , and the length direction of the protrusion 561 is toward the center of the roller brush 131 .

[0093] In this way, when the roller brush 131 rotates relative to the protrusion 561 , the protrusion 561 can comb out hair and other debris wrapped around the cleaning member 13 along the contour of the cleaning member 13 .

[0094] Specifically, the roller brush 131 can be a mop, and the protrusions 561 can rotate along the circumference of the mop to comb out the debris wrapped around the mop.

[0095] See also Figure 12In some embodiments, the scraper bar 54 includes a water guide surface 511 facing the water guide space 51 , and the water guide surface 511 is used to guide the stains to the drainage channel 52 .

[0096] In this way, dirt can be guided into the drainage channel 52 along the water guiding surface 511 , and the water guiding surface 511 can reduce leakage of dirt, thereby improving the water guiding efficiency of the water guiding space 51 .

[0097] Specifically, the water guide surface 511 is the surface of the scraper 54 facing the water guide space 51 . The water guide surface 511 may be a curved surface. The water guide surface 511 discharges particulate matter and sewage through the drainage channel 52 and collects them in the sewage tank 30 .

[0098] See also Figure 12 In some embodiments, the water guide surface 511 converges toward the drainage channel 52.

[0099] In this way, the water guide surface 511 can gather dirt toward the drainage channel 52 and guide it to the sewage tank 30 , thereby reducing the possibility of dirt remaining in the water guide space 51 and improving drainage efficiency.

[0100] Specifically, the two ends of the water guide surface 511 are located at the two ends of the main body 53 and close to the edge of the same side of the main body 53. The center of the water guide surface 511 is close to the edge of the other side of the main body 53 and located at the center of the other side, forming a "V" shape.

[0101] See also Figure 13 In some embodiments, the main body 53 forms a bottom surface 512 of the water-conducting space 51 , and the drainage channel 52 is connected to the lowest point of the bottom surface 512 of the water-conducting space 51 .

[0102] In this way, the bottom surface 512 can cover the scraper 54 and the cleaning member 13 to prevent sewage from splashing and overflowing from the water guide space 51 , thereby improving the efficiency of sewage flowing into the drainage channel 52 .

[0103] Specifically, the bottom surface 512 may be a curved surface, the highest point of the bottom surface 512 is the connection between the water guide space 51 and the cleaning member 13 , and the lowest point of the bottom surface 512 is the connection between the water guide space 51 and the drainage channel 52 .

[0104] In some embodiments, the ratio of the length of the protrusion 561 to the radius of the roller brush 131 is 0.3-0.5.

[0105] When the ratio of the length of the protrusion 561 to the radius of the roller brush 131 satisfies the above range, the protrusion 561 has a better effect of combing out entanglements, and the protrusion 561 is not likely to damage the roller brush 131.

[0106] For example, when the radius of the roller brush 131 is 30 mm, the length of the protrusion 561 can be 9 mm, 11 mm, 13 mm, 15 mm, etc.

[0107] See also Figure 13 In some embodiments, a mounting portion 57 is provided on an edge of the main body 53 opposite to the drainage portion 55 . The mounting portion 57 is formed with a rotation shaft 58 , and the wiper member 50 is mounted via the rotation shaft 58 .

[0108] In this way, the rotating shaft 58 makes it easy to install and remove the wiper element 50, and the wiper element 50 can rotate along with the rotating shaft 58, which is convenient to operate.

[0109] Specifically, the number of the rotating shafts 58 can be two, and the two rotating shafts 58 are respectively distributed close to the two ends of the length direction of the main body 53. The rotating shafts 58 can be rotatably connected to the body 10 by snapping.

[0110] Combine Figure 8 In one embodiment, when the roller brush 131 rotates counterclockwise to clean the floor, the scraping bar 54 contacts the roller brush 131 to scrape off the dirt on the roller brush 131. At the same time, the protrusion 561 is partially inserted into the roller brush 131 to comb off the entangled materials on the roller brush 131. The dirt scraped off by the scraping bar 54 enters the drainage channel 52 through the water guide space 51, and then flows to the flow channel 3151 under the action of gravity, and flows into the accommodating cavity 3144 of the sewage tank 30 through the flow channel 3151 for collection.

[0111] See also Figure 14-16 The cleaning robot 100 of the embodiment of the present application includes a cleaning component 60, and the cleaning component 60 includes a bracket 61, a cleaning member 13 and a wiper member 50. The cleaning member 13 and the wiper member 50 are both installed on the bracket 61, the wiper member 50 is in conflict with the cleaning member 13, and the bracket 61 is detachably connected to the body 10.

[0112] In the cleaning robot 100 of the embodiment of the present application, the cleaning part 13 and the wiper part 50 are both installed on the bracket 61, and the bracket 61 is detachably connected to the body 10, so that the cleaning part 13 and the wiper part 50 can be removed from the body 10 together with the bracket 61 for easy cleaning and convenient operation.

[0113] Specifically, the cleaning component 60 is arranged at the bottom of the body 10, and the bracket 61 may include a support shaft 611 and a side plate 612. The support shaft 611 may be a rectangular strip, and the side plate 612 may be a curved sheet. The side plate 612 can be connected to the body 10 and form a partial circumferential contour of the cleaning robot 100. The support shaft 611 is arranged along the normal of the side plate 612 and on the concave side. The cleaning element 13 is arranged below the support shaft 611 along the axial direction of the support shaft 611, and the wiper element 50 can be arranged on the support shaft 611 along the circumference of the cleaning element 13.

[0114] See also Figure 16 and Figure 17 In some embodiments, a mounting portion 57 is formed on an edge of the main body 53 opposite to the scraper strip 54 , and the mounting portion 57 is connected to the bracket 61 .

[0115] In this way, the wiper member 50 can be installed and removed through the mounting portion 57 and the bracket 61, so that the wiper member 50 can be cleaned separately.

[0116] Specifically, the mounting portion 57 can be fixed to the main body 53 by welding or the like, or can be integrally formed with the main body 53 . The mounting portion 57 can be connected to the bracket 61 by a snap fastener or by a latch or the like.

[0117] See also Figure 17 and Figure 18 In some embodiments, the bracket 61 is formed with a slot 613 , and the rotating shaft 58 is rotatably engaged in the slot 613 .

[0118] In this way, when the rotating shaft 58 rotates close to the cleaning member 13, the scraper strip 54 can be brought into contact with the cleaning member 13; the rotating shaft 58 is rotatably engaged in the card slot 613, which is convenient for the detachable connection between the wiper member 50 and the bracket 61; in addition, when the rotating shaft 58 rotates away from the cleaning member 13, the wiper member 50 can be separated from the cleaning member 13, which is convenient for cleaning the wiper member 50 and the cleaning member 13.

[0119] Specifically, the mounting portion 57 may protrude outwardly along a tangential direction of the main body 53. The number of the retaining grooves 613 may be two. The two retaining grooves 613 are disposed on a side of the support shaft 611 proximal to the wiper element 50 and protrude outwardly. They are distributed axially along the support shaft 611, near both ends of the support shaft 611. The retaining grooves 613 may have a circular cross-section. The two rotation shafts 58 are coaxially engaged with the two retaining grooves 613, respectively, allowing the rotation shafts 58 to rotate within the retaining grooves 613. The mounting portion 57 and retaining grooves 613 protrude from the wiper element 50 and the bracket 61 to form a mounting space, preventing the rotation of the rotation shaft 58 from interfering with the bracket 61.

[0120] See also Figure 17 and Figure 18 In some embodiments, the slot 613 forms an installation opening 614 , and the rotating shaft 58 is assembled and disassembled through the installation opening 614 .

[0121] In this way, the rotating shaft 58 can be inserted into the installation opening 614 and engaged with the locking groove 613, so that the wiper element 50 and the cleaning element 13 can be easily assembled and disassembled.

[0122] Specifically, the mounting opening 614 is located above the card slot 613, the two ends of the rotating shaft 58 are connected to the wiper element 50, and there is a square hole 59 in the middle. During installation, the rotating shaft 58 is engaged into the card slot 613 from above the card slot 613 through the mounting opening 614, and the wiper element 50 rotates close to the cleaning element 13, so that the bracket 61 enters the square hole 59, limiting the axial movement of the bracket 61 and the wiper element 50 relative to the cleaning element 13.

[0123] See also Figure 16 In some embodiments, the cleaning member 13 includes a roller brush 131, the wiper member 50 is located on one radial side of the roller brush 131, and the scraper bar 54 scrapes off the stains on the roller brush 131 during the rotation of the roller brush 131. The axial direction of the rotating shaft 58 is parallel to the axial direction of the roller brush 131.

[0124] In this way, the space used by the rotating shaft 58 in the radial direction of the roller brush 131 can be reduced, and the space used by the wiper member 50 in the radial direction of the roller brush 131 can be further reduced, thereby making the cleaning robot 100 compact.

[0125] Specifically, the scraper bar 54 and the main body 53 can be arranged at an acute angle. After the main body 53 is installed, the scraper bar 54 can be inclined relative to the roller brush 131. As the roller brush 131 rolls, the scraper bar 54 can contact the roller brush 131 at an oblique angle, allowing the scraper bar 54 to quickly and effectively scrape dirt off the roller brush 131 during the rolling process. In some embodiments, the main body 53 and scraper bar 54 can be made of stainless steel to prevent rust from contact with dirty water, thereby increasing the service life of the wiper element 50. The angle between the scraper bar 54 and the main body 53 and the width of the scraper bar 54 can be set based on the distance between the main body 53 and the roller brush 131 after installation on the bracket 61.

[0126] See also Figure 19 and Figure 20 In some embodiments, the body 10 includes a shell 62 and an elastic component 63 arranged on the shell 62. The elastic component 63 is located on the side of the wiper member 50 away from the cleaning member 13. The elastic component 63 abuts against the wiper member 50 and provides a force to the wiper member 50 toward the cleaning member 13.

[0127] In this way, under the action of the elastic component 63 , the wiper member 50 can continuously contact the cleaning member 13 , thereby maintaining the wiping strength of the wiper member 50 and improving the wiping effect of the wiper member 50 .

[0128] Specifically, the side of the shell 62 can be arc-shaped, the upper and lower surfaces of the shell 62 can be flat, the number of elastic components 63 can be two, and the two elastic components 63 rest on the main body 53 along the axial direction of the cleaning member 13, so that the scraper 54 can contact the cleaning member 13.

[0129] See also Figure 21 In some embodiments, the elastic component 63 includes an elastic member 631 and a pressing block 632 . The elastic member 631 is connected to the pressing block 632 and applies elastic force to the pressing block 632 . The pressing block 632 abuts against the wiper member 50 .

[0130] In this way, the elastic member 631 can provide an elastic force to the pressing block 632 toward the wiper member 50 , so that the pressing block 632 can provide an acting force to the wiper member 50 toward the cleaning member 13 , thereby causing the wiper member 50 to come into contact with the cleaning member 13 .

[0131] Specifically, the elastic member 631 can be an elastic element such as a spring. One end of the elastic member 631 is fixed to the upper surface of the housing 62, and the other end is connected to the pressure block 632. When the distance between the housing 62 and the pressure block 632 is less than the original length of the elastic member 631, the elastic member 631 is in a compressed state. The elastic force applied to the pressure block 632 enables the pressure block 632 to provide a force to the wiper member 50 toward the cleaning member 13. The pressure block 632 can be a hollow structure with a downward inverted triangle shape. The elastic member 631 is located within the hollow structure. The elastic force can be concentrated on the main body 53 through the lower convex portion of the inverted triangle.

The sewage tank 30 is detachably connected to the body 10, and the sewage tank 30 is formed with a flow channel 3151. The sewage tank 30 includes a surrounding wall 72 and a first protrusion 73 provided on one side of the surrounding wall 72. The surrounding wall 72 is located at one end of the flow channel 3151, and the first protrusion 73 protrudes from the surface of the surrounding wall 72 toward the body 10. When the sewage tank 30 is installed to the body 10, the first protrusion 73 abuts against the wiper member 50 to push the wiper member 50 to move relative to the body 10 and allows the drain portion 55 to bear against the surrounding wall 72.

[0133] In the cleaning robot 100 of the embodiment of the present application, during the installation of the sewage tank 30 to the body 10, the wiper member 50 abuts against the first protrusion 73 of the sewage tank 30 so that the wiper member 50 can be accurately matched with the sewage tank 30, thereby reducing the collision between the drainage portion 55 of the wiper member 50 and the surrounding wall 72 of the sewage tank 30 during the installation process, thereby reducing the wear of the wiper member 50 and the sewage tank 30 and improving the service life of the cleaning robot 100.

[0134] Specifically, the first protrusion 73 can be provided on the box cover 315, and the surrounding wall 72 can be the circumferential contour of the box cover 315. The surrounding wall 72 is formed with a notch, and the first protrusion 73 is engaged with the notch. The first protrusion 73 and the box cover 315 can be assembled or integrally formed. For example, the first protrusion 73 and the box cover 315 can be assembled and fixed by welding or integrally formed by injection molding. The first protrusion 73 can be made of plastic, plastic glue, soft glue, rubber, etc.

[0135] In some embodiments, the wiper member 50 includes a second protrusion 70 provided on the drainage portion 55 , the second protrusion 70 protruding from the edge of the drainage port 71 . When the sewage tank 30 is installed to the body 10 , the first protrusion 73 abuts against the second protrusion 70 to push the wiper member 50 to move relative to the body 10 .

[0136] In this way, the second protrusion 70 of the wiper member 50 abuts against the first protrusion 73 of the sewage tank 30 so that the wiper member 50 can be accurately matched with the sewage tank 30, reducing the collision between the drainage portion 55 of the wiper member 50 and the surrounding wall 72 of the sewage tank 30 during the installation process, thereby reducing the wear of the wiper member 50 and the sewage tank 30 and improving the service life of the cleaning robot 100.

[0137] Specifically, the second protrusion 70 and the drain portion 55 can be assembled or integrally formed. For example, the second protrusion 70 and the drain portion 55 can be assembled and fixed by welding or injection molding. The cross-section of the drain opening 71 can be circular or square, and the shape and size of the drain opening 71 can be set according to actual needs. The second protrusion 70 can be made of plastic, plastic, soft glue, rubber, etc.

[0138] See also Figure 2 、 Figure 7 and Figure 23 In some embodiments, the second protrusion 70 includes a first guide surface 701 facing the sewage tank 30. When the sewage tank 30 is installed to the body 10, the first guide surface 701 contacts the first protrusion 73 to guide the wiper member 50 to move relative to the body 10, thereby causing the drainage portion 55 to rest against the surrounding wall 72.

[0139] In this way, the first protrusion 73 moves along the first guide surface 701 to adjust the relative position of the wiper 50 and the sewage tank 30, so that the drainage part 55 can rest on the surrounding wall 72, while reducing the wear of the drainage part 55 and the surrounding wall 72 during the installation process, thereby improving the service life of the cleaning robot 100.

[0140] Specifically, the chamfers formed by the two surfaces of the first protrusion 73 close to the body 10 and the clean water tank 20 abut against the first guide surface 701. When the sewage tank 30 moves close to the body 10, the first protrusion 73 abuts against the first guide surface 701, causing the wiper member 50 to move upward relative to the body 10, thereby driving the drainage portion 55 to abut against the surrounding wall 72.

[0141] See also Figure 4 and Figure 23 In some embodiments, the first guide surface 701 extends from the bottom of the first guide surface 701 in a direction away from the body 10 relative to the height direction of the cleaning robot 100 .

[0142] In this way, when the sewage tank 30 approaches the machine body 10 , the first protrusion 73 moves along the first guide surface 701 from the top to the bottom of the first guide surface 701 , so that the drainage portion 55 approaches the surrounding wall 72 .

[0143] Specifically, the first guide surface 701 can be an inclined surface or an arc surface. The bottom of the first guide surface 701 is close to the body 10 and away from the clean water tank 20 , and the top of the first guide surface 701 is away from the body 10 and close to the clean water tank 20 .

[0144] See also Figure 2 、 Figure 7 and Figure 23 In some embodiments, the first protrusion 73 includes a second guide surface 731 facing away from the body 10. During the disassembly of the sewage tank 30 and the body 10, the second guide surface 731 contacts the second protrusion 70 to guide the wiper member 50 to move relative to the body 10, thereby separating the drainage portion 55 from the surrounding wall 72.

[0145] In this way, the second protrusion 70 moves along the second guide surface 731 to adjust the relative position of the wiper 50 and the sewage tank 30, so that the drainage part 55 can be separated from the surrounding wall 72, while reducing the wear of the drainage part 55 and the surrounding wall 72 during the installation process, thereby improving the service life of the cleaning robot 100.

[0146] Specifically, the chamfers formed by the second protrusion 70 on the two surfaces facing the sewage tank 30 and the body 10 abut against the second guide surface 731. When the sewage tank 30 moves away from the body 10, the second protrusion 70 abuts against the second guide surface 731, causing the wiper member 50 to move upward relative to the body 10, thereby driving the drainage portion 55 to separate from the surrounding wall 72.

[0147] See also Figure 4 and Figure 23 In some embodiments, the second guide surface 731 extends from the bottom of the second guide surface 731 toward the body 10 relative to the height direction of the cleaning robot 100 .

[0148] In this way, when the second protrusion 70 moves along the second guide surface 731 from the bottom to the top of the second guide surface 731 , the sewage tank 30 moves away from the machine body 10 , so that the drainage portion 55 is separated from the surrounding wall 72 .

[0149] Specifically, the second guide surface 731 can be an inclined surface or an arc surface. The bottom of the second guide surface 731 is located on the surface of the box cover 315 , and the top of the second guide surface 731 is connected to the upper surface of the first protrusion 73 .

[0150] See also Figure 10 and Figure 22 In some embodiments, the sewage tank 30 includes a tank cover 315 and a sealing member 75 disposed on the tank cover 315 . The tank cover 315 is formed with a flow channel 3151 , and the sealing member 75 is formed with at least a portion of the surrounding wall 72 .

[0151] In this way, the sealing member 75 can prevent sewage from overflowing from the flow channel 3151 , thereby reducing the risk of sewage contaminating the sewage tank 30 and the ground, and improving the cleaning efficiency of the cleaning robot 100 .

[0152] Specifically, the sealing member 75 can be made of rubber material. The sealing member 75 forms a surrounding wall 72 around a portion of the contour of the flow channel 3151 . The drainage portion 55 fits the surrounding wall 72 to prevent sewage from overflowing from the flow channel 3151 .

[0153] See also Figure 11 and Figure 22 In some embodiments, the surrounding wall 72 includes a top surface 721. Along the width direction of the flow channel 3151, the top surface 721 is concave from both sides to the middle position to form a concave portion 722. The drainage portion 55 rests on the top surface 721 and fits with the concave portion 722.

[0154] In this way, the drainage portion 55 is engaged with the recessed portion 722 so that the sewage in the wiper element 50 can flow from the drainage portion 55 into the flow channel 3151 , thereby reducing the risk of sewage leakage.

[0155] Specifically, in other embodiments, along the length direction of the wiper member 50, the bottom surface 512 of the drainage portion 55 gathers and protrudes from both sides to the middle position to form a protrusion 74. The protrusion 74 of the drainage portion 55 engages with the recessed portion 722 of the surrounding wall 72 so that sewage can flow from the drainage portion 55 to the flow channel 3151.

[0156] See also Figure 24 The cleaning system 1000 of the embodiment of the present application includes a base station 200 and a cleaning robot 100 , and the cleaning robot 100 is in contact with the base station 200 .

[0157] In this way, the base station 200 can provide an accommodating space for the cleaning robot 100 and charge the cleaning robot 100 .

[0158] Specifically, the base station 200 includes a discharge circuit. When the cleaning robot 100 contacts the base station 200, the cleaning robot 100 obtains electrical energy through the discharge circuit of the base station 200 to charge the cleaning robot 100. The base station 200 has a storage space for accommodating the cleaning robot 100. When the cleaning robot 100 is not in use, needs to be charged, needs to replenish cleaning fluid, or needs to collect stains, the cleaning robot 100 resides in the storage space. When the floor needs to be cleaned, the cleaning robot 100 enters the storage space and moves along the floor while cleaning the floor.
