[0038] The embodiments of the present invention are described in detail below, and 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] Reference below Figure 1-Figure 5 A cleaning assembly 20 according to an embodiment of the first aspect of the present invention is described.

[0040] like Figure 1-Figure 5 As shown, the cleaning assembly 20 according to the first embodiment of the utility model includes: an output shaft 21, a cleaning member 22 and a driving motor 23.

[0041] The output shaft 21 is arranged obliquely relative to the vertical direction; the cleaning member 22 is fixed to the lower end of the output shaft 21, and the cleaning member 22 is provided with a plurality of cleaning parts 221, and the plurality of cleaning parts 221 are arranged on the same side of the output shaft 21 in the radial direction; the driving motor 23 is connected to the output shaft 21 to drive the output shaft 21 to rotate. The cleaning member 22 is rotatable between a first position and a second position. In the first position, the cleaning member 22 is suitable for contacting the surface 200 to be cleaned, and in the second position, the cleaning member 22 is suitable for separating from the surface 200 to be cleaned.

[0042] For example, the output shaft 21 is tilted relative to a direction perpendicular to the surface 200 to be cleaned. The cleaning member 22 is fixed to the lower end position of the output shaft 21 in the axial direction, and the cleaning member 22 is detachably connected to the output shaft 21. The cleaning portion 221 is arranged on the cleaning member 22, and the number of the cleaning portions 221 can be multiple, for example, the number of the cleaning portions 221 can be two, three, four, five and six or more. Multiple cleaning portions 221 are arranged on the same side of the output shaft 21 in the radial direction. The drive motor 23 is connected to the output shaft 21, and the drive motor 23 can be fixed on the housing 10 of the cleaning robot 100. The drive motor 23 can provide rotational kinetic energy to drive the output shaft 21 to rotate, thereby driving the cleaning portion 221 on the cleaning member 22 to rotate with the cleaning member 22.

[0043] When the cleaning member 22 is in the first position, the cleaning portion 221 on the cleaning member 22 contacts the surface to be cleaned 200. When the cleaning member 22 is in the second position, the cleaning portion 221 on the cleaning member 22 is separated from the surface to be cleaned 200. Under the driving action of the driving motor 23, the cleaning member 22 can rotate around the output shaft 21 between the first position and the second position to achieve the cleaning work of the surface to be cleaned 200. The cleaning member 22 can also stop rotating when in the second position to stop the cleaning work of the surface to be cleaned 200, and make the cleaning portion 221 on the cleaning member 22 lift and separate from the surface to be cleaned 200.

[0044] It should be noted that in the prior art, in order to achieve active lifting of the cleaning piece, a lifting device such as a screw is usually added inside the cleaning component, or the cleaning part of the cleaning piece is rotated to shrink it. This not only increases the cost, but also reduces the overall reliability of the cleaning piece, and also affects the cleaning efficiency of the cleaning piece, thereby affecting the user experience.

[0045] In this embodiment, when the cleaning member 22 works normally, the driving motor 23 outputs rotational kinetic energy to drive the output shaft 21 to rotate, thereby driving the cleaning portion 221 on the cleaning member 22 to rotate around the output shaft 21 with the cleaning member 22. When the cleaning member 22 rotates to the first position, the cleaning portion 221 on the cleaning member 22 contacts the surface 200 to be cleaned. When the cleaning member 22 rotates from the first position to the second position, since the output shaft 21 is tilted relative to the vertical, the cleaning member 22 is in an inclined state with one side high and the other side low, so the cleaning portion 221 on the cleaning member 22 can be gradually lifted with the rotation of the output shaft 21. When the cleaning member 22 rotates to the second position, the cleaning portion 221 on the cleaning member 22 is separated from the surface 200 to be cleaned. Conversely, when the cleaning member 22 rotates from the second position to the first position, the cleaning portion 221 on the cleaning member 22 can be gradually lowered with the rotation of the output shaft 21.

[0046] In this way, the cleaning parts 221 arranged on the same side in the radial direction of the output shaft 21 can realize the rise and fall of the cleaning parts 221 in the direction perpendicular to the surface 200 to be cleaned by rotating around the inclined output shaft 21. The cleaning assembly 20 does not need to be provided with an additional lifting device such as a screw or the like inside, nor does it need to be provided with a device for rotating and contracting the cleaning part 221, so that the active lifting of the cleaning member 22 can be realized. As a result, the structure of the cleaning assembly 20 can be simplified, the installation of the cleaning assembly 20 can be facilitated, the cost can be effectively reduced, and the reliability of the structure can be effectively improved.

[0047] In addition, the continuous rotation of the cleaning member 22 between the first position and the second position can make the cleaning portion 221 on the cleaning member 22 constantly contact and separate from the surface 200 to be cleaned, thereby, the cleaning portion 221 on the cleaning member 22 can clean the surface 200 to be cleaned, and at the same time, it can effectively avoid the secondary pollution caused by the garbage on the surface 200 to be cleaned near the second position being blown away by the cleaning portion 221, thereby effectively improving the cleaning efficiency. When the cleaning portion 221 on the cleaning member 22 needs to stop rotating and separate from the surface 200 to be cleaned, the cleaning member 22 rotates from other positions to the second position, at which time the driving motor 23 stops working, the cleaning member 22 stops rotating and stays in the second position, the cleaning portion 221 on the cleaning member 22 separates from the surface 200 to be cleaned, and the cleaning assembly 20 stops cleaning the surface 200 to be cleaned, thereby avoiding the cleaning portion 221 on the cleaning member 22 from causing secondary pollution to the cleaned surface, thereby effectively improving the cleaning effect.

[0048] According to the cleaning component 20 of the embodiment of the utility model, by arranging multiple cleaning parts 221 on the same side of the cleaning member 22 in the radial direction of the output shaft 21, and installing the cleaning component 20 at an angle, the cleaning member 22 can be brought into contact with and separated from the surface to be cleaned 200 during rotation, effectively preventing garbage from being blown away by the cleaning member 22 and avoiding secondary contamination of the cleaning surface, thereby effectively improving the cleaning efficiency and further effectively improving the user experience. In addition, the cleaning component 20 has a simple structure, is easy to assemble, and has a low cost.

[0049] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the cleaning assembly 20 further includes a position sensor 24 , which is configured to detect the rotational position of the cleaning member 22 .

[0050] Specifically, the position sensor 24 can be in various forms, for example, the position sensor 24 can be a Hall sensor, which has the advantages of firm structure, small size, light weight, long life, low power consumption, pollution resistance and corrosion resistance. The position sensor 24 can detect the specific rotation position of the cleaning member 22 when working.

[0051] When the cleaning member 22 works normally, the cleaning member 22 rotates around the inclined output shaft 21, and the cleaning portion 221 on the cleaning member 22 cleans the surface 200 to be cleaned by constantly contacting and separating from the surface 200 to be cleaned. At this time, the position sensor 24 does not work. When the cleaning portion 221 on the cleaning member 22 needs to stop rotating and separate from the surface 200 to be cleaned, the position sensor 24 starts working. When the cleaning member 22 rotates to the second position around the inclined output shaft 21, the position sensor 24 detects the rotation position of the cleaning member 22 and outputs a signal of the rotation position of the cleaning member 22, and the driving motor 23 stops working. At this time, the cleaning member 22 stops rotating and stays at the second position, and the cleaning portion 221 of the cleaning member 22 separates from the surface 200 to be cleaned.

[0052] In this embodiment, a position sensor 24 is set in the cleaning component 20. When the cleaning portion 221 on the cleaning member 22 needs to stop rotating and detach from the surface 200 to be cleaned, the position sensor 24 can detect that the cleaning member 22 has rotated to the second position, thereby effectively detecting the position of the cleaning portion 221 and controlling the cleaning portion 221 to detach from the surface 200 to be cleaned, thereby effectively avoiding the cleaning portion 221 from causing secondary contamination to the cleaned surface.

[0053] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the position sensor 24 is disposed on the output shaft 21 for detecting the rotation angle of the output shaft 21 .

[0054] For example, the position sensor 24 is arranged at the upper end of the output shaft 21 in the axial direction, and the detection component on the position sensor 24 is fixedly connected to the upper end of the output shaft 21 in the axial direction. When the detection component on the position sensor 24 is working, the rotation angle of the output shaft 21 can be detected, and then the rotation position of the cleaning member 22 fixed to the lower end of the output shaft 21 can be detected. When the cleaning member 22 rotates to the second position around the inclined output shaft 21, the detection component on the position sensor 24 detects that the rotation angle of the output shaft 21 reaches the preset angle, and the position sensor 24 outputs a signal to control the cleaning member 22 to stay at the second position and make the cleaning portion 221 separate from the surface 200 to be cleaned.

[0055] Therefore, by setting a sensor on the output shaft 21 for detecting the rotation angle of the output shaft 21, the rotation position of the cleaning member 22 fixed to the lower end of the output shaft 21 and the position of the cleaning portion 221 on the cleaning member 22 can be effectively detected, thereby ensuring the accuracy and reliability of the detection result.

[0056] In one embodiment of the present invention, Figure 1 and Figure 2As shown, the cleaning assembly 20 further includes a transmission mechanism 25 , through which the driving motor 23 is transmission-connected to the output shaft 21 .

[0057] It should be noted that transmission connection refers to connecting two or more parts together through a certain assembly method to achieve the transmission of force or power. Transmission connection can effectively transfer force or power from one part to another, so that the entire system can operate normally. The two parts of the transmission connection can be directly or indirectly connected, as long as the force transmission can be achieved.

[0058] For example, the output end of the driving motor 23 is connected to one end of the transmission mechanism 25, and the other end of the transmission mechanism 25 is connected to the output shaft 21. When the cleaning member 22 works normally, the driving motor 23 outputs rotational kinetic energy to drive the transmission mechanism 25 to rotate, the transmission mechanism 25 drives the output shaft 21 to rotate, and the output shaft 21 drives the cleaning member 22 and the cleaning portion 221 on the cleaning member 22 to rotate.

[0059] In this embodiment, by providing a transmission mechanism 25 in the cleaning assembly 20, the rotational kinetic energy output by the driving motor 23 can be effectively transmitted to the transmission mechanism 25, and finally effectively transmitted to the output shaft 21. In addition, the transmission mechanism 25 can also effectively achieve the effect of decelerating and increasing the torque of the output shaft 21, thereby effectively reducing the rotation speed of the output shaft 21 and effectively increasing the torque of the output shaft 21.

[0060] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a driving gear 232 is fixed on the motor shaft 231 of the driving motor 23, an output gear 211 is fixed on the output shaft 21, and the transmission mechanism 25 includes a first gear 251 and a second gear 252 fixed coaxially, the first gear 251 is meshed with the driving gear 232, and the second gear 252 is meshed with the output gear 211.

[0061] For example, the driving gear 232 on the motor shaft 231 of the driving motor 23 is fixed to the lower end of the motor shaft 231, and the driving gear 232 can rotate together with the motor shaft 231. The output gear 211 on the output shaft 21 is fixed to the middle position of the output shaft 21, and the output gear 211 can rotate together with the output shaft 21. The first gear 251 and the second gear 252 of the transmission mechanism 25 are coaxially fixed, and the first gear 251 can rotate coaxially with the second gear 252. Further, the diameter of the first gear 251 is larger than that of the second gear 252.

[0062] When the cleaning member 22 is working normally, the driving motor 23 outputs rotational kinetic energy to drive the motor 23 shaft to rotate, the motor shaft 231 drives the driving gear 232 to rotate, the driving gear 232 drives the first gear 251 to rotate, the first gear 251 drives the second gear 252 to rotate, the second gear 252 drives the output shaft 21 to rotate, the output shaft 21 drives the cleaning member 22 and the cleaning part 221 on the cleaning member 22 to rotate, and the cleaning part 221 rotates to clean the surface 200 to be cleaned.

[0063] Thus, by providing the driving gear 232, the output gear 211, the first gear 251 and the second gear 252, the rotational kinetic energy output by the motor shaft 231 of the driving motor 23 can be effectively transmitted to the driving gear 232, the first gear 251, the second gear 252 and the output gear 211 in sequence, and finally effectively transmitted to the output shaft 21. In addition, the output gear 211 on the output shaft 21 can further achieve the effect of reducing speed and increasing torque on the output shaft 21.

[0064] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the cleaning component 20 also includes: a box body 26, a mounting cavity 260 is defined in the box body 26, the transmission mechanism 25 is arranged in the mounting cavity 260, a first through hole and a second through hole are formed on the box body 26, the motor shaft 231 of the drive motor 23 passes through the first through hole and extends into the mounting cavity 260, and the lower end of the output shaft 21 passes through the second through hole and extends out of the box body 26.

[0065] For example, the housing 26 has a mounting cavity 260, and the driving gear 232 on the motor shaft 231, the output gear 211 on the output shaft 21, and the first gear 251 and the second gear 252 of the transmission mechanism 25 are all arranged in the mounting cavity 260 of the housing 26. The housing 26 is provided with a first through hole and a second through hole, and further, the first through hole is located on the upper side wall of the housing 26, and the second through hole is located on the lower side wall of the housing 26, and the shapes of the first through hole and the second through hole can be circular. The motor shaft 231 of the driving motor 23 extends into the mounting cavity 260 through the first through hole and is fixedly connected to the driving gear 232, and the lower end of the output shaft 21 extends out of the housing 26 through the second through hole and is connected to the cleaning member 22.

[0066] In this embodiment, by providing a box 26 in the cleaning assembly 20, the driving gear 232, the output gear 211 and the transmission mechanism 25 can be provided in the installation cavity 260 of the box 26, thereby effectively protecting the driving gear 232, the output gear 211 and the transmission mechanism 25. At the same time, the provision of the box 26 can play a role in sealing and dustproofing.

[0067] In one embodiment of the present invention, Figure 1 and Figure 2As shown, the box body 26 includes a base 261 and a cover body 262 . The base 261 and the cover body 262 are detachably connected and cooperate to define a mounting cavity 260 .

[0068] For example, the base 261 of the box 26 is arranged above the cover 262, and the cover 262 is located below the base 261. Further, the base 261 can be installed on the cleaning robot 100, and the cover 262 is provided with a rotating shaft extending up and down along the direction where the output shaft 21 is located, and the first gear 251 and the second gear 252 of the transmission mechanism 25 are rotatably arranged on the rotating shaft. The base 261 and the cover 262 are detachably connected, and when the base 261 and the cover 262 are installed together, an installation cavity 260 in the box 26 is formed. Further, the connection method of the base 261 and the cover 262 can adopt a connection method of a snap connection.

[0069] In this embodiment, by providing a detachably connected base 261 and cover 262 on the box 26, the convenience of installing the box 26 can be effectively improved, thereby effectively improving the assembly efficiency of the cleaning assembly 20. At the same time, it is convenient for maintenance personnel to repair and maintain the driving gear 232, the output gear 211 and the transmission mechanism 25 in the box 26, thereby effectively reducing the maintenance cost.

[0070] In one embodiment of the present invention, Figure 3 As shown, in the circumferential direction of the output shaft 21, the angle between the two outermost cleaning parts 221 among the plurality of cleaning parts 221 is less than or equal to 180°. For example, the angle between the two outermost cleaning parts 221 among the plurality of cleaning parts 221 may be 170°, 160°, 150°, 140°, 130°, and 120°.

[0071] For example, the number of cleaning parts 221 is five, and the angle between the two cleaning parts 221 located at the outermost sides of the plurality of cleaning parts 221 is 120°. For example, the number of cleaning parts 221 is two, and the angle between the two cleaning parts 221 is 120°.

[0072] In this embodiment, the angle between the two outermost cleaning parts 221 of the plurality of cleaning parts 221 is set to be less than or equal to 180°, so that when the cleaning member 22 is in the first position, the cleaning part 221 on the cleaning member 22 contacts the surface 200 to be cleaned, and the cleaning member 22 can provide effective cleaning coverage. In addition, when the cleaning member 22 is in the second position, the cleaning part 221 on the cleaning member 22 can be separated from the surface 200 to be cleaned.

[0073] In one embodiment of the present invention, Figure 1-Figure 3As shown, the cleaning member 22 is a side brush, and the cleaning portion 221 is a bristle. The side brush can be used to clean edges, corners, and hard-to-reach areas. The bristles can penetrate into gaps and effectively remove dust and fine particles, and are particularly suitable for cleaning the surfaces of floors, carpets, or tiles. Furthermore, the softness of the bristles can be adjusted according to the different hardness of the cleaning object, so that it can be effectively cleaned without damaging the cleaning surface. The bristles can be made of wear-resistant materials to ensure that the cleaning component 20 can still maintain a good cleaning effect after long-term use.

[0074] This embodiment can effectively improve the quality of cleaning work and protect the surface 200 to be cleaned by respectively configuring the cleaning member 22 and the cleaning portion 221 as a side brush and bristles. At the same time, it can enable the cleaning component 20 to clean a variety of surfaces, thereby effectively expanding the types of surfaces that the cleaning component 20 can clean.

[0075] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the cleaning member 22 also includes a fixed disk 222 and a fixed rod 223. The fixed disk 222 is fixed at the lower end of the output shaft 21. The fixed rod 223 is connected to the circumference of the fixed disk 222 and extends radially outward along the output shaft 21. There are multiple fixed rods 223, and the multiple fixed rods 223 correspond one-to-one to the multiple cleaning parts 221. A fixing hole is formed on the fixed rod 223, and one end of the cleaning part 221 is inserted into the fixing hole and fixed to the fixed rod 223.

[0076] For example, the fixed disk 222 is fixedly connected to the lower end of the output end. Further, the shape of the projection of the fixed disk 222 in the direction where the output shaft 21 is located can be circular, and the fixed disk 222 and the lower end of the output end can be connected by a snap-on connection. A fixed rod 223 is arranged on the circumference of the fixed disk 222. The number of the fixed rods 223 can be multiple, for example, the number of the fixed rods 223 can be two, three, four, five and six or more. Multiple fixed rods 223 are arranged on the same side in the radial direction of the output shaft 21, and each fixed rod 223 extends outwardly in the radial direction of the output shaft 21. The fixed rod 223 is provided with a fixing hole at one end away from the output shaft 21, one end of the cleaning portion 221 is inserted into the fixing hole and fixedly connected to the fixed rod 223, and the other end of the cleaning portion 221 can contact or separate from the surface 200 to be cleaned.

[0077] When the cleaning member 22 works normally, the rotation of the output shaft 21 drives the fixed disk 222 to rotate around the output shaft 21, and the fixed disk 222 drives the fixed rod 223 and the cleaning portion 221 on the fixed rod 223 to rotate around the output shaft 21. The continuous rotation of the cleaning member 22 around the output shaft 21 between the first position and the second position can make the cleaning portion 221 continuously rotate up and down around the output shaft 21, thereby making the cleaning portion 221 continuously contact and separate from the surface to be cleaned 200. When the cleaning portion 221 on the fixed rod 223 needs to stop rotating and separate from the surface to be cleaned 200, the position sensor 24 detects that the cleaning member 22 rotates to the second position, and the output shaft 21 stops rotating, thereby making the fixed disk 222 stop rotating, thereby making the fixed rod 223 and the cleaning portion 221 stop rotating, and at this time, the cleaning portion 221 separates from the surface to be cleaned 200.

[0078] In this embodiment, by providing a fixed disk 222 and a fixed rod 223 in the cleaning member 22, when the cleaning member 22 works normally, the rotational kinetic energy can be sequentially transmitted from the output shaft 21 to the fixed disk 222 and the fixed rod 223, and finally effectively transmitted to the cleaning portion 221, so that the cleaning portion 221 can continuously rotate up and down around the output shaft 21. At the same time, the cleaning portion 221 can be installed in the fixing hole of the fixed rod 223, so that the length of the cleaning portion 221 can be effectively reduced, and then the overall structural strength of the cleaning member 22 can be effectively improved.

[0079] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the outer end of the fixing rod 223 in the radial direction of the output shaft 21 is bent downward. For example, the outer end of the fixing rod 223 away from the fixing plate 222 in the radial direction of the output shaft 21 is bent downward, and the cleaning portion 221 extends downward along the direction where the bent portion of the fixing rod 223 is located.

[0080] Thus, by bending the fixing rod 223 downward at the radial outer end of the output shaft 21, the contact force between the cleaning part 221 and the surface 200 to be cleaned can be effectively increased when the cleaning part 221 contacts the surface 200, thereby effectively improving the cleaning effect. At the same time, the overall structural strength of the cleaning member 22 can also be further improved.

[0081] like Figure 4 and Figure 5 As shown, the cleaning robot 100 according to the second aspect of the present invention comprises: a housing 10 and a cleaning component 20 according to the first aspect of the present invention, wherein the cleaning component 20 is arranged in the housing 10 and the cleaning member 22 is located at the lower side of the housing 10 .

[0082] For example, the cleaning assembly 20 is fixed to the housing 10 of the cleaning robot 100 by bolts, the output shaft 21 of the cleaning assembly 20 is tilted toward the outside of the cleaning robot 100, and the cleaning member 22 of the cleaning assembly 20 is arranged at the lower side of the housing 10. Further, the cleaning portion 221 on the cleaning member 22 is a bristle, and the number of the cleaning assembly 20 can be multiple, for example, the number of the cleaning assembly 20 can be two, three, four, five, six or more. When there are two cleaning assemblies 20, the cleaning assemblies 20 can be symmetrically arranged on both sides of the housing 10 of the cleaning robot 100.

[0083] When the cleaning robot 100 cleans the surface to be cleaned 200, the rotational kinetic energy output by the motor shaft 231 of the driving motor 23 of the cleaning component 20 drives the driving gear 232 to rotate, the driving gear 232 drives the first gear 251 to rotate, the first gear 251 drives the second gear 252 to rotate, the second gear 252 drives the output shaft 21 to rotate, the output shaft 21 drives the fixed disk 222 to rotate around the output shaft 21, and the fixed disk 222 drives the fixed rod 223 and the bristles on the fixed rod 223 to rotate around the output shaft 21. The continuous rotation of the cleaning member 22 around the output shaft 21 between the first position and the second position can make the bristles rotate up and down around the output shaft 21 continuously, and then make the bristles contact and separate from the surface to be cleaned 200 continuously, so that the cleaning robot 100 can not only clean the surface to be cleaned 200, but also avoid secondary pollution caused by the bristles hitting the garbage inside the cleaning robot 100.

[0084] When the cleaning robot 100 stops cleaning and continues to move, the position sensor 24 starts working. When the cleaning member 22 rotates to the second position around the inclined output shaft 21, the position sensor 24 detects the rotation position of the cleaning member 22 and outputs a signal of the rotation position of the cleaning member 22. The driving motor 23 stops working. At this time, the cleaning member 22 stops rotating and stays in the second position. The bristles of the cleaning member 22 are detached from the surface 200 to be cleaned, and the bristles are facing the center position of the robot. The cleaning component 20 stops cleaning the surface 200 to be cleaned, thereby preventing the bristles on the cleaning member 22 from causing secondary contamination to the cleaned surface.

[0085] According to the cleaning robot 100 of the embodiment of the utility model, by setting the cleaning component 20 of the above-mentioned first aspect embodiment, the contact and separation of the cleaning member 22 with the surface to be cleaned 200 can be achieved during the rotation process, thereby effectively preventing garbage from being blown away by the cleaning member 22 and avoiding secondary contamination of the cleaning surface, thereby effectively improving the cleaning efficiency and further effectively improving the user experience. In addition, the cleaning component 20 has a simple structure, is easy to assemble, and has a low cost.

[0086] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the cleaning robot 100 further includes: a mopping assembly, two cleaning assemblies 20 respectively arranged on the left and right sides of the housing 10 , and the mopping assembly is provided on the housing 10 and arranged on the rear sides of the two cleaning assemblies 20 .

[0087] For example, the cleaning robot 100 has two cleaning components 20, which are symmetrically arranged on both sides of the housing 10 of the cleaning robot 100. Further, the two cleaning components 20 are arranged outside the cleaning robot 100. The mopping component of the cleaning machine is arranged on the housing 10 behind the two cleaning components 20.

[0088] When the cleaning assembly 20 is working, the cleaning member 22 rotates around the output shaft 21 to realize the rotational rise and fall of the bristles, thereby realizing the contact and separation of the bristles with the surface to be cleaned 200, and then realizing the cleaning work of the bristles on the surface to be cleaned 200. When the mopping assembly is working, the mopping assembly contacts the surface to be cleaned 200, and the cleaning robot 100 can mop the surface to be cleaned 200 through the mopping assembly.

[0089] The cleaning robot 100 of this embodiment has multiple cleaning modes, including: a sweeping mode, a mopping mode, and a mopping and sweeping mode.

[0090] When the cleaning robot 100 starts the sweeping mode, the cleaning component 20 starts working, and the cleaning member 22 rotates around the output shaft 21 to realize the rotation and rise and fall of the bristles, thereby realizing the contact and separation of the bristles with the surface to be cleaned 200, and then realizing the cleaning work of the bristles on the surface to be cleaned 200. At this time, the mopping component does not work and is separated from the surface to be cleaned 200.

[0091] When the cleaning robot 100 starts the mopping mode, the cleaning member 22 rotates to the second position and stays in the second position. At this time, the cleaning component 20 stops working, the bristles are located on the inside of the robot and separated from the surface to be cleaned 200, and the mopping component starts working. The cleaning robot 100 mops the surface to be cleaned 200 through the mopping component.

[0092] When the cleaning robot 100 starts the mopping and sweeping mode, the cleaning component 20 and the mopping component work simultaneously, and the cleaning robot 100 can sweep and mop the surface to be cleaned 200 at the same time.

[0093] The cleaning robot 100 of the present embodiment, by providing a mopping component in the cleaning robot 100, can enable the cleaning robot 100 to have a sweeping mode, a mopping mode, and a mopping and sweeping mode, thereby effectively expanding the applicable scenarios of the cleaning robot 100 and further effectively improving the user experience.
