[0047] In order to further illustrate the technical means and effects adopted by this application to achieve the intended application purpose, the following is combined with the drawings and implementation methods. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0049] At present, swimming pools, as people's sports venues, need to be cleaned regularly. People now usually use cleaning robots to clean swimming pools regularly.

[0050] However, during the cleaning process, existing cleaning robots have the problem that the moving wheel assemblies on both sides of the cleaning robot are suspended relative to the cleaning surface, causing the bottom of the cleaning robot to be in close contact with the surface to be cleaned, and the cleaning robot moves slowly or has difficulty in moving. For example, if the surface to be cleaned is uneven, and the bottom of the cleaning robot is in close contact with the protruding part, the moving wheel assemblies on both sides of the cleaning robot may be suspended relative to the cleaning surface, causing the cleaning robot to move slowly or has difficulty in moving, resulting in low cleaning efficiency of the cleaning robot.

[0051] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0052] Please also see Figures 1 to 7 One embodiment of the present application proposes a cleaning robot 100. The cleaning robot 100 includes a cleaning body 11, a moving wheel assembly 12, a garbage collection assembly 13, a water pump assembly 14 and a support assembly 15. The moving wheel assembly 12 is arranged on opposite sides of the cleaning body 11. The moving wheel assembly 12 is used to drive the cleaning body 11 to move. The garbage collection assembly 13 is arranged on the cleaning body 11 and is used to collect garbage. The water pump assembly 14 is arranged on the cleaning body 11. The water pump assembly 14 is used to suck garbage and water from the bottom of the cleaning body 11 and spray water outward from the top of the cleaning body 11. The support assembly 15 is located at the bottom of the cleaning body 11. The support assembly 15 is used to support the side wall of the area to be cleaned when the moving wheel assembly 12 is suspended in the air, so that the bottom of the cleaning body 11 contacts the side wall through the support assembly 15.

[0053] See Figure 3 As shown, A represents the side wall of the area to be cleaned, and the side wall can be a convex wall. During the cleaning process of the cleaning robot 100, when the moving wheel assembly 12 is suspended in the air, the support assembly 15 located at the bottom of the cleaning body 11 is supported on the side wall of the area to be cleaned, ensuring that there is a gap between the bottom of the cleaning body 11 and the side wall of the area to be cleaned during the garbage collection process of the garbage collection assembly 13, avoiding direct contact between the bottom of the cleaning body 11 and the side wall of the area to be cleaned, thereby reducing the friction between the bottom of the cleaning body 11 and the side wall of the area to be cleaned, ensuring that the cleaning robot 100 can move smoothly, and thereby improving the cleaning efficiency of the cleaning robot 100.

[0054] In some embodiments of the present application, the support assembly 15 includes a first cleaning brush 150. The first cleaning brush 150 has a first state and a second state. When the moving wheel assembly 12 is suspended in the air, the first cleaning brush 150 is in the first state, creating a gap between the cleaning body 11 and the sidewall. When the moving wheel assembly 12 is in contact with the bottom wall of the area to be cleaned, the first cleaning brush 150 is in the second state.

[0055] In some embodiments of the present application, the first cleaning brush 150 is used to clean garbage in the area to be cleaned, and is also used to support the side wall of the area to be cleaned when the moving wheel assembly 12 is suspended in the air, so that there is a gap between the bottom of the cleaning body 11 and the side wall.

[0056] In some embodiments of the present application, due to the weight of the cleaning body 11 itself, if a gap is created between the bottom and the side wall of the cleaning body 11 by the first cleaning brush 150, the hardness of the first cleaning brush 150 needs to be within a preset hardness range. For example, the existing first cleaning brush 150 can be thickened and / or hardened so that the hardness of the first cleaning brush 150 reaches within a preset hardness range, or the first cleaning brush 150 can be made of a material within a preset hardness range.

[0057] In some embodiments of the present application, the area to be cleaned may include multiple surfaces. For example, for a swimming pool, the area to be cleaned may include a bottom wall and / or a side wall perpendicular to the bottom wall. When the cleaning robot 100 uses the first cleaning brush 150 to clean the bottom wall or side wall of the swimming pool, the first cleaning brush 150 may be in different states. Specifically, when the cleaning robot 100 cleans the side wall of the area to be cleaned, the moving wheel assembly 12 is suspended in the air and supported on the side wall of the area to be cleaned by the first cleaning brush 150, so that the first cleaning brush 150 is in a first state. When the cleaning robot 100 cleans the bottom wall of the area to be cleaned, the moving wheel assembly 12 is not suspended in the air, the moving wheel assembly 12 is in contact with the bottom wall of the area to be cleaned, and the first cleaning brush 150 is in a second state.

[0058] In some embodiments of the present application, when the first cleaning brush 150 is in the first state, due to the gap between the bottom and the side wall of the cleaning body 11, it is possible to ensure that the cleaning robot 100 can move smoothly, thereby improving the cleaning efficiency of the cleaning robot 100. When the first cleaning brush 150 is in the second state, the bottom of the cleaning body 11 is supported on the bottom wall of the area to be cleaned by the moving wheel assembly 12, and the bottom of the cleaning body 11 does not contact the bottom wall of the area to be cleaned. This can reduce the friction between the bottom of the cleaning body 11 and the bottom wall of the area to be cleaned, ensure that the cleaning robot 100 can move smoothly, thereby improving the cleaning efficiency of the cleaning robot 100.

[0059] In some embodiments of the present application, see Figure 4 and Figure 7 As shown, the water pump assembly 14 includes a drive motor 140. The drive motor 140 has a first power and a second power. When the moving wheel assembly 12 is suspended in the air, the drive motor 140 operates at the first power to place the first cleaning brush 150 in the first state. When the moving wheel assembly 12 is in contact with the bottom wall of the area to be cleaned, the drive motor 140 operates at the second power to place the first cleaning brush 150 in the second state, wherein the second power is greater than the first power.

[0060] In some embodiments of the present application, when the cleaning robot 100 is cleaning the bottom wall, the moving wheel assembly 12 contacts the bottom wall of the area to be cleaned. Since the first cleaning brush 150 is thickened and / or hardened, there may be a technical problem that the first cleaning brush 150 cannot contact the bottom wall of the area to be cleaned. Therefore, in order to ensure that the first cleaning brush 150 can operate normally when cleaning the bottom wall, the cleaning robot 100 is operated by using different power to increase the contact area between the first cleaning brush 150 and the bottom wall, thereby improving the cleaning efficiency of the cleaning robot 100.

[0061] In some embodiments of the present application, the cleaning robot 100 further includes a drive mechanism (not shown). The drive mechanism is connected to the first cleaning brush 150. When the moving wheel assembly 12 is suspended in the air, the drive mechanism drives the first cleaning brush 150 to move toward the side wall, so that the first cleaning brush 150 is in a first state. When the moving wheel assembly 12 contacts the bottom wall of the area to be cleaned, the drive mechanism drives the first cleaning brush 150 to move away from the bottom wall of the area to be cleaned, so that the first cleaning brush 150 is in a second state.

[0062] In some embodiments of the present application, when the cleaning robot 100 is cleaning the area to be cleaned, if the moving wheel assembly 12 is suspended in the air and the support assembly 15 is supported on the side wall, a gap exists between the bottom and the side wall of the cleaning body 11. The driving mechanism drives the first cleaning brush 150 to move toward the side wall (in a direction perpendicular to the side wall of the area to be cleaned) to ensure the gap between the bottom and the side wall, thereby ensuring that the cleaning robot 100 can move smoothly and improving the cleaning efficiency of the cleaning robot 100. If the moving wheel assembly 12 contacts the bottom wall of the area to be cleaned, in order to ensure that there is a gap between the bottom and the bottom wall of the cleaning body 11, the driving mechanism drives the first cleaning brush 150 to move away from the bottom wall (in a direction perpendicular to the bottom wall of the area to be cleaned) to ensure that the cleaning robot 100 can move smoothly, thereby improving the cleaning efficiency of the cleaning robot 100.

[0063] In some embodiments of the present application, two first cleaning brushes 150 may be included. The two first cleaning brushes 150 are respectively located at two ends of the cleaning body 11 , and the garbage collecting assembly 13 is located between the two first cleaning brushes 150 .

[0064] In some embodiments of the present application, the cleaning efficiency of the cleaning robot 100 can be further improved by installing two first cleaning brushes 150 at both ends of the cleaning body 11. For example, if the cleaning robot 100 moves forward and the first cleaning brush 150 at the front end does not clean thoroughly, the first cleaning brush 150 at the rear end can be used to clean the area to be cleaned again, further ensuring that the area to be cleaned is cleaned thoroughly.

[0065] In some embodiments of the present application, two cleaning brushes are located at both ends of the cleaning body 11. By arranging the garbage collection component 13 between the two first cleaning brushes 150, during the process of the garbage collection component 13 collecting garbage, the two cleaning brushes can cooperate with each other so that the garbage collection component 13 can better collect garbage, thereby improving the cleaning efficiency of the cleaning robot 100.

[0066] In some embodiments of this application, see Figure 5 As shown, the cleaning robot 100 further includes a second cleaning brush 16. The support assembly 15 includes a protrusion 151 fixedly disposed at the bottom of the cleaning body 11. The lowest end of the protrusion 151 is no higher than the lowest end of the moving wheel assembly 12. When the moving wheel assembly 12 is suspended in the air, the cleaning body 11 is separated from the side wall by the protrusion 151.

[0067] In some embodiments of the present application, the second cleaning brush 16 is used to clean garbage in the area to be cleaned and / or is also used to support the sidewalls of the area to be cleaned when the moving wheel assembly 12 is suspended in the air, so that a gap is formed between the bottom and the sidewalls of the cleaning body 11. The second cleaning brush 16 and the first cleaning brush 150 can be the same or different.

[0068] In some embodiments of the present application, the protrusion 151 may include, but is not limited to, at least one protrusion and at least one ridge, which is not limited in this embodiment. For example, the protrusion 151 may also include a skeleton structure.

[0069] In some embodiments of the present application, a protrusion 151 is provided at the bottom of the cleaning body 11, and the lowest end of the protrusion 151 is not higher than the lowest end of the moving wheel assembly 12. When the moving wheel assembly 12 is suspended in the air, it can be supported on the side wall by the protrusion 151 to ensure a gap between the bottom and the side wall of the cleaning body 11, so as to reduce the friction between the bottom and the side wall, ensure that the cleaning robot 100 can move smoothly, and improve the cleaning efficiency of the cleaning robot 100.

[0070] In some embodiments of this application, see Figure 6 As shown, the cleaning robot 100 further includes a second cleaning brush 16. The support assembly 15 includes a rolling wheel 152 disposed at the bottom of the cleaning body 11. The lowest end of the rolling wheel 152 is no higher than the lowest end of the moving wheel assembly 12. When the moving wheel assembly 12 is suspended in the air, the cleaning body 11 is separated from the side wall by the rolling wheel 152.

[0071] In some embodiments of the present application, the scroll wheel 152 may include a universal wheel, which is not limited in this embodiment. For example, the scroll wheel 152 may also include a guide roller, a steering roller, etc.

[0072] In some embodiments of the present application, since the rolling wheel 152 replaces sliding friction with rolling friction, the energy loss caused by friction is reduced. In this embodiment, a rolling wheel 152 is set at the bottom of the cleaning body 11, and the lowest end of the rolling wheel 152 is not higher than the lowest end of the moving wheel assembly 12. When the moving wheel assembly 12 is suspended in the air, the rolling wheel 152 is supported on the side wall to ensure the gap between the bottom and the side wall of the cleaning body 11. This not only reduces the friction between the bottom and the side wall, but also realizes the dynamic balance of the cleaning robot 100 through the rolling wheel 152, reduces vibration, and ensures that the cleaning robot 100 can move smoothly, thereby improving the cleaning efficiency of the cleaning robot 100.

[0073] In some embodiments of this application, see Figure 2 As shown, the cleaning robot 100 also includes a second cleaning brush 16, and the support assembly 15 includes a stopper 153 arranged around the garbage collection assembly 13. The lowest end of the stopper 153 is not higher than the lowest end of the moving wheel assembly 12. When the moving wheel assembly 12 is suspended in the air, the cleaning body 11 is separated from the side wall by the stopper 153.

[0074] In some embodiments of the present application, the stopper 153 can be a stopper 153 made of a hard material. By arranging the stopper 153 around the garbage collection assembly 13, and the lowest end of the stopper 153 is not higher than the lowest end of the moving wheel assembly 12, when the moving wheel assembly 12 is suspended in the air, it can be supported on the side wall by the stopper 153 to ensure the gap between the bottom and the side wall of the cleaning body 11, so as to reduce the friction between the bottom and the side wall, ensure that the cleaning robot 100 can move smoothly, and improve the cleaning efficiency of the cleaning robot 100.

[0075] In some embodiments of the present application, the garbage collection component 13 may include a sewage suction port 130, and the stopper 153 may include a first stop bar 1530, a second stop bar 1531 and a third stop bar 1532. The first stop bar 1530 and the second stop bar are relatively arranged on both sides of the sewage suction port 130, and the third stop bar is located between the first stop bar 1530 and the second stop bar. The first stop bar 1530, the second stop bar and the third stop bar form a garbage blocking area to prevent the collected garbage from moving around, ensuring better collection of garbage, and thereby improving the cleaning efficiency of the cleaning robot 100.

[0076] In some embodiments of the present application, a plurality of water outlets 110 are provided on the top of the cleaning body 11 , each water outlet 110 includes a plurality of inclined grilles 1100 , and the water pump assembly 14 draws water from the bottom of the cleaning body 11 and sprays it out through the grilles 1100 .

[0077] In some embodiments of the present application, each water outlet 110 includes a plurality of inclined grilles 1100. After the water sucked from the bottom of the cleaning body 11 by the water pump assembly 14 passes through the grille 1100 and is sprayed along the inclined direction of the grille 1100, a reaction force opposite to the direction of water spraying is applied to the water pump assembly 14. The reaction force can be decomposed into horizontal force and vertical force, wherein the horizontal force can drive the cleaning robot 100 to move in a direction parallel to the area to be cleaned, and the vertical force can drive the cleaning robot 100 to move in a direction perpendicular to the area to be cleaned.

[0078] In some embodiments of the present application, multiple inclined grilles 1100 are provided at each water outlet 110, so that the water sprayed by the water pump assembly 14 is in an oblique spraying state, which not only increases the horizontal force of the cleaning robot 100 and accelerates the movement speed of the cleaning robot 100 in the horizontal force direction, but also ensures the gap between the cleaning robot 100 and the area to be cleaned to ensure the smooth movement of the cleaning robot 100, thereby improving the cleaning efficiency of the cleaning robot 100.

[0079] In some embodiments of this application, see Figure 7 As shown, the moving wheel assembly 12 includes two spaced apart moving wheel groups 120 , each of which includes a front wheel 1200 , a rear wheel 1201 and a track 1202 . The track 1202 is provided on the front wheel 1200 and the rear wheel 1201 .

[0080] In some embodiments of the present application, by providing tracks 1202 on the front wheels 1200 and the rear wheels 1201, the friction between the moving wheel assembly 12 and the contact surface (for example, the bottom wall, side wall, etc. of the area to be cleaned) can be increased, thereby preventing the cleaning robot 100 from slipping and ensuring that the cleaning robot 100 can move smoothly.

[0081] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application is described with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and essence of the technical solutions of the present application.
