[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0030] Reference to "embodiment" in this document means that the specific features, structures, or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appearing at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0031] The pool robot provided by the present invention will be described in detail below in conjunction with embodiments.

[0032] Please refer to Figures 1 to 3 , Figure 1 which is the first structural schematic diagram of an embodiment of the pool robot of the present application; Figure 2 which is the second structural schematic diagram of an embodiment of the pool robot of the present application; Figure 3 is Figure 2 the enlarged schematic diagram shown at A in . An embodiment of the present application provides a pool robot 10. The pool robot 10 includes a robot main body 1 and a first cleaning assembly 2. The robot main body 1 can move along a reference plane 40. The reference plane 40 can be the bottom wall of the pool, the side wall of the pool, the water surface of the pool, etc. The robot main body 1 includes a first side wall 11, a second side wall 12, and a third side wall 13.

[0033] Among them, the first side wall 11 is the side wall facing the forward direction X of the robot main body 1. The first side wall 11 is provided with a sewage suction port 111. The sewage suction port 111 is used to suck water flow and stains, etc. into the robot main body 1. The stains can be garbage floating in the pool, scale or black stains accumulated in the pool, etc. The second side wall 12 and the third side wall 13 are both connected to the first side wall 11. The second side wall 12 and the third side wall 13 are located on both sides of the first side wall 11. The second side wall 12 and the third side wall 13 can be oppositely arranged. For example, the second side wall 12 is located on the left side of the robot main body 1, and the third side wall 13 is located on the right side of the robot main body 1. The first cleaning assembly 2 is arranged on the robot main body 1. The first cleaning assembly 2 can clean the pool. The first cleaning assembly 2 is used to expand the cleaning range of the sewage suction port 111.

[0034] Specifically, the cleaning range of the sewage suction port 111 refers to the range where the sewage suction port 111 can affect the water flow and stains when the sewage suction port 111 is in the state of sucking water flow and stains. The first cleaning assembly 2 can be directly arranged on the outer surface of the second side wall 12 or the third side wall 13. Or the first cleaning assembly 2 can also be arranged inside the robot main body 1.

[0035] With the above settings, when the robot body 1 moves forward, since the sewage suction port 111 is located on the first side wall 11, the sewage suction port 111 efficiently sucks in stains as the robot body 1 moves forward. The first cleaning component 2 can play an auxiliary cleaning role and expand the cleaning range of the sewage suction port 111. Thus, not only the stains near the sewage suction port 111 can be cleaned, but also the stains farther away from the sewage suction port 111 can be cleaned by the first cleaning component 2, expanding the cleaning range of the pool robot 10 and achieving high cleaning efficiency.

[0036] The first cleaning component 2 can expand the cleaning range of the sewage suction port 111 by agitating the water flow towards the sewage suction port 111 or enhancing the suction force of the sewage suction port 111, etc., without limitation here. In a specific embodiment, the first cleaning component 2 is rotatably arranged on the robot body 1. When the first cleaning component 2 rotates relative to the robot body 1, the first cleaning component 2 agitates the water flow outside the cleaning range of the sewage suction port 111, causing the water flow to flow towards the sewage suction port 111.

[0037] Among them, the rotation direction of the first cleaning component 2 can be set according to the actual situation, as long as it can agitate the water flow to flow towards the sewage suction port 111. For example, along the forward direction X, when the first cleaning component 2 is closer to the left side of the robot body 1 relative to the sewage suction port 111, the first cleaning component 2 rotates clockwise. When the first cleaning component 2 is closer to the right side of the robot body 1 relative to the sewage suction port 111, the first cleaning component 2 rotates counterclockwise.

[0038] In another specific embodiment, the first cleaning component 2 can generate suction. The first cleaning component 2 sucks the water flow and stains outside the cleaning range of the sewage suction port 111 and guides the water flow and stains to the sewage suction port 111.

[0039] In another other specific embodiment, the first cleaning component 2 can perform contact cleaning. When the robot body 1 moves along the pool wall of the pool, the first cleaning component 2 contacts the pool wall of the pool and cleans the pool wall. The stains attached to the pool wall are cleaned into the water by the first cleaning component 2 and sucked into the robot body 1 by the sewage suction port 111.

[0040] The above-mentioned robot body 1 can also be provided with a power structure, a filtering structure, a receiving cavity, etc. The power structure is used to provide power for the robot body 1. The robot body 1 can be driven by the power structure to move along the reference plane 40. The filtering structure can separate the water flow and stains, that is, play a role in filtering stains. The receiving cavity can accommodate the stains filtered out by the filtering structure. The robot body 1 can be configured with the receiving cavity, the filtering structure and the sewage suction port 111 in cooperation. The filtering structure filters the water flow sucked in by the sewage suction port 111, separating the stains from the water flow. The stains are retained in the receiving cavity, and the cleaned water flow is discharged from the robot body 1.

[0041] The motion state of the robot main body 1 can be determined according to the situation of the reference plane 40. For example, when the reference plane 40 is the bottom wall of the pool, the robot main body 1 can sink into the pool and move along the bottom wall of the pool. The pool robot 10 can clean the stains attached to the bottom. When the reference plane 40 is the water surface of the pool, the robot main body 1 can float on the water surface and move along the water surface. The pool robot 10 can clean the stains floating on the water surface.

[0042] In one embodiment, the first cleaning assembly 2 at least partially extends to be exposed outside the second side wall 12 or the third side wall 13. The first cleaning assembly 2 can clean the area near the second side wall 12 or the third side wall 13 to expand the cleaning range of the dirt suction port 111.

[0043] The distribution form of the first cleaning assembly 2 can be set according to the actual situation. In a specific embodiment, the first cleaning assembly 2 at least partially extends to be exposed outside the second side wall 12. In another specific embodiment, the first cleaning assembly 2 at least partially extends to be exposed outside the third side wall 13. In another specific embodiment, the first cleaning assembly 2 at least partially extends to be exposed outside the second side wall 12 and the third side wall 13.

[0044] Please continue to refer to Figures 1 to 3 , in one embodiment, along the forward direction X, at least part of the orthographic projection of the first cleaning assembly 2 coincides with the orthographic projection of the dirt suction port 111. That is to say, at least part of the first cleaning assembly 2 and the dirt suction port 111 are in the same plane.

[0045] Thus, when the dirt suction port 111 cleans the pool, since at least part of the orthographic projection of the first cleaning assembly 2 coincides with the orthographic projection of the dirt suction port 111, the stains cleaned by the first cleaning assembly 2 can quickly reach near the dirt suction port 111, and the movement distance is shorter. The first cleaning assembly 2 can efficiently bring the stains to the dirt suction port 111, and the pool robot 10 has a better cleaning effect and high cleaning efficiency.

[0046] The positional relationship between the first cleaning assembly 2 and the dirt suction port 111 can be set according to the actual situation. In a specific embodiment, when projected along the forward direction X, the orthographic projection of the first cleaning assembly 2 completely coincides with the orthographic projection of the dirt suction port 111. In another specific embodiment, when projected along the forward direction X, the orthographic projection of the first cleaning assembly 2 partially coincides with the orthographic projection of the dirt suction port 111.

[0047] In one embodiment, when projected along the forward direction X, the orthographic projection of the lower end of the first cleaning component 2 coincides with the orthographic projection of the sewage suction port 111. The lower end of the first cleaning component 2 refers to the end of the first cleaning component 2 close to the bottom surface of the robot main body 1 along the direction perpendicular to the reference plane 40. The bottom surface of the robot main body 1 refers to the side surface of the robot main body 1 adjacent to the first side wall 11, the second side wall 12, and the third side wall 13, and used to contact the bottom wall or the side wall of the pool. Further, along the direction perpendicular to the reference plane 40, the sewage suction port 111 includes a first edge 1111 and a second edge 1112 arranged oppositely. When projected along the forward direction X, the orthographic projection of the first cleaning component 2 is located between the projections of the first edge 1111 and the second edge 1112.

[0048] With the above arrangement, when the first cleaning component 2 is cleaning, the stains near the second side wall 12 or the third side wall 13 can be directly carried by the first cleaning component 2 between the first edge 1111 and the second edge 1112 and directly sucked into the sewage suction port 111. The stains do not have to move a long distance along the depth direction of the pool to overcome the buoyancy of the water body, the movement is more efficient, the cleaning effect of the pool robot 10 is better, and the cleaning efficiency is high.

[0049] Please refer to Figure 4 , Figure 4 which is the third structural schematic diagram of an embodiment of the pool robot of the present application. Combining Figures 1 to 3 , in one embodiment, along the forward direction X of the robot main body 1, at least a part of the first cleaning component 2 is located in front of the sewage suction port 111. With the above arrangement, since the first cleaning component 2 is located in front of the sewage suction port 111, as the robot main body advances, the stains cleaned and driven by the first cleaning component 2 can naturally reach near the sewage suction port 111. The sewage suction port 111 can conveniently suck away the stains, and it is not easy to miss the floating stains. The pool robot 10 is cleaner and has high cleaning efficiency.

[0050] In one embodiment, the first cleaning component 2 includes a rotating brush 21 and a rotating shaft 22. The rotating brush 21 is arranged around the rotating shaft 22. The rotating shaft 22 is rotatably connected to the robot main body. The rotating brush 21 has at least one cleaning surface 2111. The cleaning surface 2111 is inclined with respect to the reference plane 40. The cleaning surface 2111 is used to contact and agitate the water flow. Specifically, when the rotating shaft 22 rotates, the rotating shaft 22 drives the rotating brush 21 to rotate. When the rotating brush 21 rotates, it drives the cleaning surface 2111 to move and agitate the water flow.

[0051] With the above settings, the first cleaning component 2 can efficiently clean and agitate the water flow by the rotating brush 21. At the same time, compared with making the cleaning surface 2111 perpendicular to the reference plane 40, the cleaning surface 2111 inclined to the reference plane 40 can agitate the water flow obliquely. Thus, when the rotating brush 21 rotates, it is not easy for the rotating brush 21 to form a water flow parallel to the advancing direction X tangentially at the edge. The stains near the edge of the rotating brush 21 will not be continuously pushed forward by this water flow and cannot reach near the dirt suction port 111, and the cleaning effect of the pool robot 10 is better.

[0052] The number of the above cleaning surfaces 2111 can be one, two, three or more, etc., which is not limited here. The rotating shaft 22 can be connected to a driving member on the robot body. The driving member drives the rotating shaft 22 to rotate. The driving member can be a motor or the like.

[0053] Specifically, in an embodiment, the cleaning surface 2111 is inclined to the reference plane 40, specifically including: an angle Y is formed between the axis of the rotating shaft 22 and the reference plane 40, and the angle Y is greater than 0 degrees and less than 90 degrees. The angle of the angle Y can be 1 degree, 5 degrees, 8 degrees, 15 degrees, 22 degrees, 25 degrees, 30 degrees, 33 degrees, 45 degrees, 60 degrees, 75 degrees, 80 degrees, etc.

[0054] Thus, by inclining the rotating shaft 22 relative to the reference plane 40, and then driving the rotating brush 21 to be inclined relative to the reference plane 40, the structure of the first cleaning component 2 is simple. At the same time, the angle Y between the axis of the rotating shaft 22 and the reference plane 40 is greater than 0 degrees and less than 90 degrees, so that the cleaning surface 2111 of the rotating brush 21 can agitate the water flow well obliquely, and it is not easy to generate cleaning dead corners, and the cleaning effect of the pool robot 10 is good.

[0055] The inclination direction of the axis of the rotating shaft 22 relative to the reference plane 40 can be set according to the actual situation. Please refer to Figures 5 to 7 , Figure 5 is the fourth structural schematic diagram of an embodiment of the pool robot of the present application; Figure 6 is the fifth structural schematic diagram of an embodiment of the pool robot of the present application; Figure 7 is the sixth structural schematic diagram of an embodiment of the pool robot of the present application. In a specific embodiment, the pool robot 10 includes a first reference plane α. The first reference plane α is perpendicular to the reference plane 40 and the advancing direction X. That is, the first reference plane α is a plane extending in the left-right direction of the robot body. The first reference plane α can be a virtual plane. The axis of the rotating shaft 22 is located in the first reference plane α.

[0056] Specifically, since an angle Y is formed between the axis of the rotating shaft 22 and the reference plane 40, and the axis of the rotating shaft 22 is located within the first reference plane α, along the second side wall 12 towards the third side wall 13, the distance from the rotating shaft 22 to the bottom surface of the robot main body gradually increases or gradually decreases. That is, the rotating shaft 22 is inclined along the second side wall 12 towards the third side wall 13. When the distance from the rotating shaft 22 to the bottom surface of the robot main body gradually increases, the distance from the rotating brush 21 to the bottom surface of the robot main body gradually decreases. When the distance from the rotating shaft 22 to the bottom surface of the robot main body gradually decreases, the distance from the rotating brush 21 to the bottom surface of the robot main body gradually increases. The bottom surface of the robot main body 1 refers to the side surface of the robot main body 1 that is adjacent to the first side wall 11, the second side wall 12, and the third side wall 13, and is used to contact the bottom wall or the side wall of the pool.

[0057] With the above settings, since the rotating shaft 22 is inclined along the second side wall 12 towards the third side wall 13. Thus, the rotating brush 21 is also inclined along the second side wall 12 towards the third side wall 13. When the rotating brush 21 rotates, it can agitate the water flow obliquely to drive the stains to the dirt suction port 111, and it is not easy to generate cleaning dead corners, and the cleaning efficiency of the pool robot 10 is high.

[0058] The inclination direction of the rotating shaft 22 can be set according to the actual situation. For example, along the second side wall 12 towards the third side wall 13, the distance from the rotating shaft 22 to the bottom surface of the robot main body gradually increases. Or along the second side wall 12 towards the third side wall 13, the distance from the rotating shaft 22 to the bottom surface of the robot main body gradually decreases.

[0059] More specifically, in a specific embodiment, a reference center line γ is provided between the second side wall 12 and the third side wall 13. The reference center line γ is perpendicular to the reference plane 40. From the direction close to the reference center line γ to the direction away from the reference center line γ, the distance from the rotating shaft 22 to the bottom surface of the pool robot 10 gradually decreases.

[0060] Specifically, the reference center line γ is located at the central position between the second side wall 12 and the third side wall 13. The reference center line γ can be a virtual straight line. When the rotating shaft 22 is closer to the second side wall 12 than the reference center line γ, that is, the distance between the rotating shaft 22 and the second side wall 12 is less than the distance between the rotating shaft 22 and the third side wall 13, along the second side wall 12 towards the third side wall 13, the distance from the rotating shaft 22 to the bottom surface of the pool robot 10 gradually increases. The distance from the rotating brush 21 to the bottom surface of the pool robot 10 gradually decreases. When the rotating shaft 22 is closer to the third side wall 13 than the reference center line γ, that is, the distance between the rotating shaft 22 and the second side wall 12 is greater than the distance between the rotating shaft 22 and the third side wall 13, along the second side wall 12 towards the third side wall 13, the distance from the rotating shaft 22 to the bottom surface of the pool robot 10 gradually decreases. The distance from the rotating brush 21 to the bottom surface of the pool robot 10 gradually increases.

[0061] With the above settings, the rotating brush 21 can generate water flows converging towards the sewage suction port 111 on both the second side wall 12 and the third side wall 13. Stains can be well guided into the sewage suction port 111 by the water flows, and the pool robot 10 has a good cleaning effect.

[0062] In another specific embodiment, the pool robot 10 includes a second reference plane β, as Figure 7 shown. The second reference plane β is perpendicular to the reference plane 40. The second reference plane β intersects with the forward direction X. That is, the second reference plane β is a plane extending along the front-back direction of the robot body. The second reference plane β can be a virtual plane. The axis of the rotating shaft 22 is located within the second reference plane β.

[0063] Specifically, since an angle Y is formed between the axis of the rotating shaft 22 and the reference plane 40, and the axis of the rotating shaft 22 is located within the second reference plane β, along the forward direction X, the distance from the rotating shaft 22 to the bottom surface of the robot body gradually increases or gradually decreases. That is, the axis of the rotating shaft 22 is inclined along the forward direction X. When the distance from the rotating shaft 22 to the bottom surface of the robot body gradually increases, the distance from the rotating brush 21 to the bottom surface of the robot body gradually decreases. When the distance from the rotating shaft 22 to the bottom surface of the robot body gradually decreases, the distance from the rotating brush 21 to the bottom surface of the robot body gradually increases.

[0064] With the above settings, since the rotating shaft 22 is inclined along the forward direction X, the rotating brush 21 is also inclined along the forward direction X. When the rotating brush 21 rotates, it can better gather the stains near the second side wall 12 or the third side wall 13 to the vicinity of the sewage suction port 111, and the pool robot 10 has high cleaning efficiency.

[0065] Please continue to refer to Figures 1 to 7 , in an embodiment, the rotating brush 21 includes a plurality of cleaning parts 211. The cleaning parts 211 are arranged around the outer periphery of the rotating shaft 22. The cleaning parts 211 extend along the axial direction of the rotating shaft 22. One side of the cleaning part 211 forms a cleaning surface 2111. The cleaning surface 2111 is the side surface of the cleaning part 211 facing the rotating direction of the rotating shaft 22. At least part of the cleaning part 211 is made of a flexible material. And / or, at least part of the cleaning part 211 is made of a rigid material.

[0066] Thus, by arranging the cleaning parts 211 along the axial direction of the rotating shaft 22, the rotating brush 21 has a simple structure and is easy to manufacture. When the inclined rotating shaft 22 rotates, the cleaning parts 211 can tilt and stir the water flow relative to the reference plane 40, and the pool robot 10 is not likely to form cleaning dead corners during cleaning, and has a good cleaning effect.

[0067] The material of the cleaning part 211 can be determined according to the actual situation. In a specific embodiment, the entire cleaning part 211 is made of a flexible material. In another specific embodiment, the entire cleaning part 211 is made of a rigid material. In still another specific embodiment, part of the cleaning part 211 is made of a flexible material and the other part is made of a rigid material. A flexible material refers to a material that can undergo elastic deformation. A rigid material refers to a material that cannot undergo elastic deformation.

[0068] When the cleaning part 211 is made of a flexible material, it can be bristles, rubber sheets, etc. When the cleaning part 211 is made of a rigid material, it can be plastic blades, metal blades, etc., as long as it can be used to clean stains, and there is no limitation here. The number of the cleaning parts 211 can be one, two, three or more, etc., and there is no limitation here.

[0069] Specifically, in another embodiment, the cleaning surface 2111 is inclined with respect to the reference plane 40, specifically including: the axis of the rotating shaft 22 is perpendicular to the reference plane 40. The rotating brush 21 includes a plurality of cleaning parts 211. The cleaning parts 211 are arranged around the outer periphery of the rotating shaft 22. The cleaning parts 211 are inclined or bent in the rotating direction of the rotating shaft 22. One side of the cleaning part 211 forms the cleaning surface 2111. The cleaning surface 2111 is the side surface of the cleaning part 211 facing the rotating direction of the rotating shaft 22.

[0070] Thus, the rotating shaft 22 can be simply vertically arranged on the robot main body 1, and the structural design is flexible. When the rotating shaft 22 rotates, the inclined and bent cleaning parts 211 can stir the water flow obliquely, and it is not easy to form cleaning dead corners when the pool robot 10 is cleaning, and the cleaning effect is good.

[0071] Please continue to refer to Figures 1 to 7 , in an embodiment, the first cleaning assembly 2 is arranged on the second side wall 12 and / or the third side wall 13. Thus, the first cleaning assembly 2 can conveniently clean the stains near the second side wall 12 and / or the third side wall 13, and the cleaning efficiency of the pool robot 10 is high.

[0072] The installation position of the first cleaning assembly 2 can be set according to the actual situation. In a specific embodiment, the first cleaning assembly 2 is arranged on the second side wall 12. In another specific embodiment, the first cleaning assembly 2 is arranged on the third side wall 13.

[0073] Further, there are two first cleaning assemblies 2. The two first cleaning assemblies 2 are respectively arranged on the second side wall 12 and the third side wall 13. Thus, the two first cleaning assemblies 2 can simultaneously clean the stains near the second side wall 12 and the third side wall 13, the cleaning range of the pool cleaning robot is larger, and the cleaning efficiency is high.

[0074] In another embodiment, the first sidewall 11 extends forward in the advancing direction X with a fixing arm 112. The first cleaning assembly 2 is arranged on the fixing arm 112. The fixing arm 112 is arranged close to the second sidewall 12 and / or the third sidewall 13.

[0075] With the above arrangement, the structure of the pool robot 10 is flexibly designed, and the first cleaning assembly 2 can conveniently clean the stains near the second sidewall 12 and / or the third sidewall 13, and the pool robot 10 has high cleaning efficiency.

[0076] Furthermore, there are two fixing arms 112. The two fixing arms 112 are respectively arranged at opposite ends of the first sidewall 11. The two first cleaning assemblies 2 are respectively arranged on the fixing arms 112. Thus, the two first cleaning assemblies 2 can simultaneously clean the stains near the second sidewall 12 and the third sidewall 13, the cleaning range of the pool cleaning robot is larger, and the cleaning efficiency is high.

[0077] Please continue to refer to Figures 1 to 7 , in an embodiment, the pool robot 10 further includes a second cleaning assembly 3. The second cleaning assembly 3 is used to clean the pool. The second cleaning assembly 3 is rotatably arranged between the second sidewall 12 and the third sidewall 13. The second cleaning assembly 3 is located in front of the dirt suction port 111 along the advancing direction X. Along the advancing direction X, at least part of the orthographic projection of the second cleaning assembly 3 coincides with the orthographic projection of the dirt suction port 111.

[0078] With the above arrangement, the second cleaning assembly 3 can clean in front of the dirt suction port 111, which can further expand the cleaning range of the pool robot 10. In addition, since at least part of the orthographic projection of the second cleaning assembly 3 coincides with the orthographic projection of the dirt suction port 111, the stains stirred by the second cleaning assembly 3 can be conveniently driven towards the dirt suction port 111, and the pool robot 10 has high cleaning efficiency.

[0079] The rotation direction of the second cleaning assembly 3 can be set according to the actual situation. For example, the rotation axis of the second cleaning assembly 3 can be parallel to the direction from the second sidewall 12 to the third sidewall 13.

[0080] In an embodiment, the robot main body can float on the water surface. When the robot main body floats on the water surface, at least part of the first cleaning assembly 2 is located below the water surface. For example, part of the first cleaning assembly 2 can be located below the water surface, or the first cleaning assembly 2 can be entirely located below the water surface.

[0081] In a specific embodiment, when the robot body floats on the water surface, half of the first cleaning component 2 is above the water surface and the other half is below the water surface. With the above arrangement, the first cleaning component 2 can conveniently clean the stains on the water surface. Additionally, when the first cleaning component 2 is inclined, the part of the first cleaning component 2 above the water surface will not stir the water flow when rotating, that is, this part will not form a water flow parallel to the forward direction X tangentially. The stains will not be continuously pushed forward by this water flow and cannot reach near the dirt suction port 111, and the cleaning effect of the pool robot 10 is better.

[0082] In another specific embodiment, when the robot body floats on the water surface, the first cleaning component 2 is entirely below the water surface. With the above arrangement, since the first cleaning component 2 is completely underwater, the first cleaning component 2 is not likely to splash water when rotating and is not likely to wet the edge of the pool.

[0083] Additionally, when the robot body floats on the water surface, the dirt suction port 111 can also be at least partially below the water surface. In a specific embodiment, half of the dirt suction port 111 is above the water surface and the other half is below the water surface. Thus, the stains near the water surface can directly enter the dirt suction port 111, and the stains do not have to overcome buoyancy to move to the dirt suction port 111, and the cleaning efficiency is high.

[0084] In another specific embodiment, when the robot body floats on the water surface, the dirt suction port 111 is entirely below the water surface. Thus, since the dirt suction port 111 is entirely underwater, it can contact a larger flow of water, and the dirt suction efficiency is high.
