Description

Technical Field

[0001] This utility model relates to the field of swimming pool cleaning technology, specifically to a cleaning robot. Background Technology

[0002] Existing pool cleaning machines typically place a roller brush between two traveling wheels to clean the pool bottom as the machine moves. However, because the working range of the roller brush is limited by the distance between the traveling wheels, it cannot effectively reach the edges near the pool walls or bottom edges, creating cleaning dead zones. This is especially true in pool corners, bends, or areas near the waterline, where the cleaning machine struggles to achieve adequate coverage, resulting in residue of dirt and algae and affecting the overall cleaning effect.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0020] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] A cleaning robot 100, please refer to Figure 1 and Figure 2The system includes a machine body 10 and a roller brush assembly 20. The roller brush assembly 20 is connected to the machine body 10, and the machine body 10 drives the roller brush assembly 20 to rotate. The roller brush assembly 20 includes a first roller brush 21 and two second roller brushes 22 arranged coaxially. The two second roller brushes 22 are respectively arranged at opposite ends of the first roller brush 21. Both the first roller brush 21 and the second roller brush 22 are detachably connected to the machine body 10. Along the axial direction of the first roller brush 21, the width of the roller brush assembly 20 is greater than or equal to the width of the machine body 10.

[0023] The cleaning robot 100 provided by this utility model, by coaxially arranging the three roller brushes in the roller brush assembly 20, and with the width of the roller brush assembly 20 being greater than or equal to the width of the machine body 10, allows the cleaning range of the cleaning robot 100 to cover the edge of the pool, avoiding the formation of cleaning dead corners, thereby improving the cleaning effect of the cleaning robot 100. At the same time, the detachable first roller brush 21 and second roller brush 22 also facilitate their disassembly, cleaning and maintenance, thereby simplifying the cleaning process and reducing maintenance costs. Through the above structural design, the cleaning robot 100 of this utility model significantly improves the cleaning coverage and maintenance convenience while maintaining high-efficiency driving performance, and can effectively overcome the problems of many cleaning blind spots, inconvenient brush replacement, and poor adaptability in the prior art, thereby achieving a more comprehensive and intelligent pool cleaning operation.

[0024] In a specific embodiment, the cleaning robot 100 is used for pool cleaning. The cleaning robot 100 moves via a walking structure; optionally, the walking structure includes a tracked structure or a wheeled structure. During the movement of the cleaning robot 100, the side of the cleaning robot 100 facing the pool wall is the bottom of the machine body 10, and the side facing away from the pool wall is the top of the machine body 10; the bottom of the machine body 10 may have a suction port for sucking up pool water into the cleaning robot 100.

[0025] In a specific embodiment, the roller brush assembly 20 can be positioned on the front and rear sides of the cleaning robot 100 along its walking direction. The first roller brush 21 and the second roller brush 22 are driven to rotate by the main body 10. The first roller brush 21 and the second roller brush 22 are the main components used for cleaning the pool walls, specifically for scrubbing and cleaning dirt and sediment on the pool bottom and side walls. As the cleaning robot 100 moves, it drives the two roller brushes to rotate against the pool wall, thereby completing the cleaning work. It is understood that both the first roller brush 21 and the second roller brush 22 are cylindrical structures, and their coaxial arrangement means that their axes coincide.

[0026] In a specific embodiment, there are two second roller brushes 22, which are respectively arranged on opposite sides of the axis of the first roller brush 21. Both the first roller brush 21 and the two second roller brushes 22 are coaxially arranged. It should be noted that the width of the roller brush assembly 20 (or the width of the machine body 10) refers to the dimension parallel to the axis of the roller brush. Therefore, the cleaning width range of the roller brush assembly 20 is greater than the maximum width of the machine body 10, allowing the roller brush to cover the cleaning area between the machine bodies 10 and the edge areas on both sides during the cleaning process. This effectively eliminates cleaning dead corners at the edge of the pool and ensures that the transition areas of the pool bottom and pool walls are thoroughly cleaned.

[0027] In a specific embodiment, both the first roller brush 21 and the second roller brush 22 are detachably connected to the machine body 10, facilitating quick disassembly and assembly when the roller brushes wear out or need replacement, thus improving maintenance convenience and service life. The first roller brush 21 and the second roller brush 22 together constitute an integrated multi-segment roller brush structure. The multi-segment and detachable structure design not only facilitates transportation and storage but also allows for the selection of brush heads with different hardness or materials according to the shape of the pool and the type of dirt, achieving targeted cleaning effects.

[0028] For some implementation methods, please refer to Figure 3 and Figure 4 The roller brush assembly 20 also includes a connector 24, the second roller brush 22 includes a locking structure 23, the connector 24 is connected to the machine body 10, the machine body 10 drives the connector 24 to rotate, and the second roller brush 22 is detachably connected to the connector 24 through the locking structure 23.

[0029] This utility model uses the locking structure 23 on the second roller brush 22 to cooperate with the connector 24 to drive the second roller brush 22 to rotate for cleaning. It can also achieve a detachable connection between the second roller brush 22 and the connector 24. The locking structure 23 can ensure the stability of the second roller brush 22 during rotation after it is connected to the locking structure 23, and prevent the second roller brush 22 from falling off during rotation.

[0030] In a specific embodiment, the connector 24 is rotatable under the drive of the machine body 10, and the connector 24 is detachably connected to the locking structure 23. The specific connection methods between the connector 24 and the locking structure 23 include, but are not limited to, one or more of the following: snap-on quick-release structure, magnetic quick-release structure, sliding quick-release structure, threaded quick-release structure, and elastic pin quick-release structure. It should be noted that the connector 24 and the locking structure 23 can be disassembled without the aid of other tools, avoiding a cumbersome disassembly process.

[0031] In a specific embodiment, the connector 24 and the locking structure 23 include a locked state and an unlocked state. The locked state means that the connector 24 and the locking structure 23 are securely connected and cannot be separated. The unlocked state means that the connector 24 and the locking structure 23 are either in contact or not connected, and can be separated or have already been separated. It is understood that when the second roller brush 22 is restricted by the connector 24 to the point that it cannot be directly removed from the connector 24, the connector 24 and the locking structure 23 are in the locked state; when the second roller brush 22 is not restricted by the connector 24 and can be removed from the connector, or when the second roller brush 22 has already been separated from the connector 24, the connector 24 and the locking structure 23 are in the unlocked state.

[0032] In a specific embodiment, there are also two connectors 24. The two connectors 24 are respectively connected to the opposite sides of the first roller brush 21, so that the two connectors 24 and the two second roller brushes 22 are connected in a one-to-one correspondence. It should be noted that the two connectors 24 and the two second roller brushes 22 can be symmetrically arranged with respect to the first roller brush 21. That is, the two second roller brushes 22 can have the same shape and structure, and the two connectors 24 can have the same shape and structure. Therefore, the installation positions of the second roller brushes 22 do not need to be distinguished between the left and right sides.

[0033] For some implementation methods, please refer to Figures 4-6 The connector 24 encloses the first space 241. The inner wall of the first space 241 is provided with a snap-fit ​​hole 242. The locking structure 23 is housed in the first space 241 and is movably connected to the connector 24 through the snap-fit ​​hole 242.

[0034] By having the connector 24 enclose the first space 241, the connector 24 forms a hollow structure, which not only reduces the overall weight but also facilitates the arrangement of the locking structure 23. At the same time, the snap-fit ​​hole 242 on the connector 24 allows the locking structure 23 located in the first space 241 to snap onto the connector 24, thereby improving the connection reliability between the connector 24 and the locking structure 23.

[0035] In a specific embodiment, the connector 24 can be a hollow cylindrical structure, and the snap-fit ​​hole 242 can be a blind hole on the inner wall of the first space 241, or the snap-fit ​​hole 242 can be a through hole penetrating the wall panel of the connector 24. The locking structure 23 is housed in the first space 241 and at least partially extends into the snap-fit ​​hole 242, thus the connector 24 and the locking structure 23 are in a locked state; when the locking structure 23 is disengaged from the snap-fit ​​hole 242, the connector 24 and the locking structure 23 are in an unlocked state.

[0036] In a specific embodiment, there can be multiple locking holes 242. After the locking structure 23 extends into the locking hole 242, the locking structure 23 cannot be disengaged from the connector 24 due to the restriction of the locking hole 242. Optionally, the locking structure 23 can adopt the form of elastic buckle, elastic sheet, or locking ball, etc., and its free end can be elastically deformed in the radial direction to achieve automatic locking or release during insertion or disassembly.

[0037] For some implementation methods, please refer to Figure 4 , Figure 6 and Figure 7 The second roller brush 22 also includes bristles 25 and a mounting member 26. The bristles 25 are sleeved on the outer periphery of the mounting member 26, the mounting member 26 surrounds the second space 261, and the connector 24 is housed in the second space 261. The locking structure 23 is connected to the inner wall of the second space 261. The mounting member 26 has a mating hole 262, which connects the inside and outside of the second space 261. At least part of the locking structure 23 extends into the mating hole 262.

[0038] The present invention provides a second space 261 for the mounting component 26, which can reduce the weight of the second roller brush 22 and provide installation space for the locking structure 23, thereby optimizing the overall structural layout. By opening a mating hole 262 on the mounting component 26, at least part of the locking structure 23 extends into the mating hole 262 to be exposed in the external space. The user can operate the locking structure 23 through the exposed part of the locking structure 23 to complete the locking or unlocking action.

[0039] In a specific embodiment, the mounting member 26 can be a hollow cylindrical structure with an inner diameter larger than the outer diameter of the connector 24, so that the mounting member 26 can be fitted around the outer periphery of the connector 24. It is understood that the brush bristles 25, mounting member 26, connector 24, and locking structure 23 together form a nested structure. The brush covers the outer surface of the mounting member 26, the mounting member 26 is fitted around the outer periphery of the connector 24, and the connector 24 is fitted around the outer periphery of the locking structure 23. The brush is used to scrub and clean dirt from the bottom and walls of the pool.

[0040] In a specific embodiment, the mounting member 26 may include an annular side plate and a bottom plate, with the side plate connected to the bottom plate. One end of the mounting member 26 opposite to the bottom plate is open, through which the mounting member 26 is installed onto the connector 24. After the second roller brush 22 is installed, the bottom plate faces the first roller brush 21, and a mating hole 262 is formed on the bottom plate. Both the bottom plate and the side plate are covered with bristles 25, but the bristles 25 are not covered at the location of the mating hole 262, thus allowing the mating hole 262 to connect the inside and outside of the second space 261.

[0041] In a specific embodiment, one end of the locking structure 23 is connected to the base plate, and at least a portion of the locking structure 23 extends into the mating hole 262 to be exposed to the external space. The user can switch between the locked and unlocked states of the second roller brush 22 by operating the locking structure 23 at the position of the mating hole 262.

[0042] For some implementation methods, please refer to Figure 7 and Figure 8 The locking structure 23 includes a snap-fit ​​member 231 and a pressing member 232. The snap-fit ​​member 231 extends at least partially into the snap-fit ​​hole 242, and the pressing member 232 extends into the mating hole 262 facing the first roller brush 21. The pressing member 232 is axially movable along the second roller brush 22. The pressing member 232 moves to squeeze the snap-fit ​​member 231 out of the snap-fit ​​hole 242.

[0043] This utility model features a locking structure 23, which includes a snap-fit ​​component 231 and a pressing component 232. The pressing component 232 moves to press the snap-fit ​​component 231, thus unlocking the device. This process does not require any tools; the user can simply press it manually, achieving the effect of quick insertion of the second roller brush 22.

[0044] In a specific embodiment, the snap-fit ​​member 231 and the pressing member 232 are separate structures, arranged sequentially along the axial direction of the second roller brush 22, with the pressing member 232 located on the side of the snap-fit ​​member 231 facing away from the first roller brush 21. The pressing member 232 is movable along the axial direction of the second roller brush 22, meaning it can move closer to or further away from the snap-fit ​​member 231 along the axial direction of the second roller brush 22. The end of the pressing member 232 facing away from the snap-fit ​​member 231 extends into and is exposed through the mating hole 262, allowing the user to press the snap-fit ​​member 231 by squeezing the pressing member 232.

[0045] For some implementation methods, please refer to Figure 8 The snap-fit ​​member 231 includes a deformable part 2311, which is deformable along the radial direction of the second roller brush 22; the deformable part 2311 is provided with a boss 2312, which extends into the snap-fit ​​hole 242; the pressing member 232 includes a guide part 2321, which is connected to the deformable part 2311 and is used to press and deform until the boss 2312 disengages from the snap-fit ​​hole 242.

[0046] This utility model can achieve a snap-fit ​​with the connector 24 by means of the boss 2312 provided on the deformable part 2311, and the deformable part 2311 can be deformed radially along the second roller brush 22, which can restrict the boss 2312 to be held in the snap-fit ​​hole 242 after snap-fit ​​to achieve locking; the guide part 2321 is connected to the deformable part 2311 and can be unlocked by axial pressing.

[0047] In a specific embodiment, the snap-fit ​​component 231 further includes a first plate 2313, a deformable portion 2311 connected to the first plate 2313, and the deformable portion 2311 has a "U"-shaped structure, with a boss 2312 disposed on the outer surface of the deformable portion 2311. The pressing component 232 includes a second plate 2322 and a button 2323, with guide portions 2321 and the button 2323 disposed on opposite sides of the second boss 2312; the guide portion 2321 is disposed on the side of the second plate 2322 facing the first plate 2313, and the button 2323 extends into the mating hole 262. The guide portion 2321 presses the "U"-shaped deformable portion 2311, causing the deformable portion 2311 to deform radially along the second roller brush 22.

[0048] In a specific embodiment, the guide portion 2321 extends along the axial direction of the second roller brush 22, and the end of the guide portion 2321 away from the second platform 2322 contacts the deformable portion 2311, and the guide portion 2321 is connected to the outer surface of the deformable portion 2311 facing the connector 24. Thus, during the process of switching from the locked state to the unlocked state, when the guide portion 2321 moves axially, it will press the deformable portion 2311 inward to dislodge the boss 2312.

[0049] In a specific embodiment, the end of the guide portion 2321 away from the second plate 2322 is constricted, and the end of the deformable portion 2311 that contacts the guide portion 2321 is also constricted. That is, both the ends of the guide portion 2321 and the deformable portion 2311 have smooth inclined surfaces. The inclined surfaces of both the deformable portion 2311 and the guide portion 2321 not only increase the contact area to improve the reliability of the press-to-unlock mechanism, but also provide a guiding function, achieving a labor-saving effect.

[0050] In a specific embodiment, there are two deformable portions 2311, which are respectively connected to opposite sides of the first plate 2313 in the radial direction. Each of the two opposite surfaces of the deformable portions 2311 has a boss 2312, meaning there are two bosses 2312. There are also two snap-fit ​​holes 242, with each boss 2312 corresponding to one of the two mating holes 262. There are also two guide portions 2321.

[0051] In a specific embodiment, when the second roller brush 22 is installed on the connector 24, the boss 2312 automatically resets and embeds itself after being inserted into the snap-fit ​​hole 242 of the connector 24, thereby forming a reliable snap-fit ​​engagement with the snap-fit ​​hole 242 and realizing the stable fixation between the second roller brush 22 and the connector 24; when it is necessary to disassemble the second roller brush 22, pressing or pulling the pressing member 232 can release the locking state, thereby realizing quick disassembly and replacement.

[0052] For some implementation methods, please refer to Figure 7 and Figure 8The locking structure 23 also includes a reset member 233, which is deformable along the axial direction of the second roller brush 22. The two ends of the reset member 233 are respectively connected to a snap-fit ​​member 231 and a pressing member 232. Specifically, the reset member 233 includes one or more of a spring, a spring sheet, and elastic rubber.

[0053] This invention provides a reset member 233 to provide a reset force to the pressing member 232, so as to ensure that the pressing member 232 and the locking member 231 can automatically return to the initial locked position after the pressing force is released.

[0054] In a specific embodiment, the reset element 233 can be a spring, with its two ends connected to the first plate 2313 and the second plate 2322, respectively. The spring is deformable along the axial direction of the second roller brush 22, i.e., it can undergo compression or stretching deformation. During the process of switching from the locked state to the unlocked state, the second plate 2322 moves closer to the first plate 2313 to compress the spring. After the boss 2312 disengages from the snap-fit ​​hole 242, the spring reverses its direction to move the second plate 2322 away from the first plate 2313, thereby achieving reset after pressing.

[0055] In other embodiments, the reset member 233 can also use a magnet. Specifically, two magnets with the same magnetic properties can be installed on the first plate 2313 and the second plate 2322 respectively. After the boss 2312 disengages from the snap-fit ​​hole 242, the second plate 2322 moves away from the first plate 2313 under the repulsive force of the magnets of the same polarity, thereby achieving reset after pressing. It can be understood that the function of the reset member 233 is to provide a reset force for the pressing member 232 to ensure that the pressing member 232 and the snap-fit ​​member 231 can automatically return to their initial positions after the pressing force is released.

[0056] In other embodiments, when the second roller brush 22 needs to be installed, the user simply inserts the mounting piece 26 into the snap-fit ​​hole 242 of the connector 24. The snap-fit ​​piece 231 is automatically compressed and slides into the hole under the action of the inclined surface or guide structure, and then returns to its original position under the elastic force of the elastic reset piece 233, thereby completing automatic locking and realizing quick assembly. When disassembly is required, the user presses the pressing piece 232 to drive the snap-fit ​​piece 231 to move in the radial direction, causing it to disengage from the snap-fit ​​hole 242, thereby easily removing the second roller brush 22 from the connector 24.

[0057] For some implementation methods, please refer to Figure 2 and Figure 3 The main body 10 of the machine includes a body 11, a walking component 12 and a transmission component 13. The walking component 12 is disposed on both sides opposite to the body 11. The transmission component 13 connects the roller brush component 20 and the walking component 12. The transmission component 13 is disposed between the first roller brush 21 and the second roller brush 22.

[0058] By setting a transmission component 13 to connect the roller brush component 20, the present invention can use the power on the walking component 12 to drive the roller brush component 20, so that the roller brush can obtain consistent rotational power and achieve synchronous rotation.

[0059] In a specific embodiment, the walking assembly 12 further includes a drive component, which can be a drive motor, used to drive the walking assembly 12 to move the cleaning robot 100 as a whole. The walking assembly 12 is disposed on the left and right sides of the body 11, used to support and drive the cleaning robot 100 to move smoothly on different surfaces such as the bottom wall and side wall of the pool.

[0060] In a specific embodiment, the walking component 12 can be a tracked walking structure, including a belt and at least two pairs of wheel sets, wherein each pair of wheel sets includes a rotating wheel, and the track is connected to the rotating wheel. The rotation of the rotating wheel drives the track to rotate synchronously, thereby driving the cleaning robot 100 to move as a whole. Alternatively, the walking component 12 can also be a wheeled walking structure, that is, it moves directly by wheels.

[0061] In a specific embodiment, one end of the transmission component 13 is connected to the walking component 12, and the other end is connected to the roller brush component 20. Specifically, it can be connected to the connector 24 of the roller brush component 20. The transmission component 13 and the walking component 12 rotate synchronously, that is, the roller brush component 20 and the walking component 12 share a set of drive motors. The driving force of the walking component 12 drives the roller brush component 20 to rotate synchronously, realizing the coordinated linkage of cleaning and walking. Preferably, there are two sets of transmission components 13. The two sets of transmission components 13 are respectively connected to the walking components 12 on both sides of the body 11, and the two sets of transmission components 13 drive the two second roller brushes 22 respectively.

[0062] For some implementation methods, please refer to Figure 5 and Figure 6 The transmission assembly 13 includes a housing 131, a first synchronous pulley 132, a second synchronous pulley 133, and a synchronous belt 134. The first synchronous pulley 132 is connected to the walking assembly 12, the second synchronous pulley 133 is connected to the roller brush assembly 20, and the synchronous belt 134 connects the first synchronous pulley 132 and the second synchronous pulley 133. The first synchronous pulley 132, the second synchronous pulley 133, and the synchronous belt 134 are all housed in the housing 131.

[0063] This utility model can simplify the transmission cost while increasing the transmission distance by setting a transmission method of synchronous pulley and synchronous belt 134, which is lower in cost than the transmission gear transmission method; at the same time, the housing 131 can protect the first synchronous pulley 132, the second synchronous pulley 133 and the synchronous belt 134 from interfering with the rotation of the roller brush.

[0064] In a specific embodiment, the first synchronous wheel 132 is provided with a connecting portion, which is exposed on the outside of the housing 131 and is used for transmission connection with the walking component 12, thereby transmitting the driving force of the walking component 12 to the inside of the transmission component 13. The second synchronous wheel 133 is respectively transmissionally connected to the first roller brush 21 and the second roller brush 22, so that the three-section roller brush can obtain consistent rotational power and achieve synchronous rotation.

[0065] In a specific embodiment, the timing belt 134 is engaged with the first timing pulley 132 and the second timing pulley 133, respectively, to transmit torque between them. This allows the driving force to be transmitted from the walking assembly 12 to the second timing pulley 133 via the first timing pulley 132, and then to the second timing pulley 133, which in turn drives the first roller brush 21 and the second roller brush 22 to rotate. When the walking assembly 12 rotates, the first timing pulley 132 rotates synchronously under the drive of the connecting part, which in turn drives the second timing pulley 133 to rotate via the timing belt 134, thereby realizing the automatic cleaning action of the roller brush assembly 20.

[0066] In other embodiments, the transmission assembly 13 can also be a gear drive, that is, the transmission assembly 13 includes a housing 131 and at least two gears, with the gears meshing for transmission. Alternatively, it can also be a linkage drive, that is, the transmission assembly 13 includes components such as a housing 131, a linkage, and a rotating shaft. It is understood that the function of the transmission assembly 13 is to transfer the kinetic energy of the walking assembly 12 to the brush assembly 20, so any component capable of kinetic energy transfer can be used as the transmission assembly 13 in this utility model.

[0067] For some implementation methods, please refer to Figures 1-4 The transmission assembly 13 includes a first transmission assembly 13A and a second transmission assembly 13B. The first roller brush 21 includes a first sub-roller brush 21A and a second sub-roller brush 21B that are coaxial. The first transmission assembly 13A is disposed between the first sub-roller brush 21A and a second roller brush 22, and the second transmission assembly 13B is disposed between the second sub-roller brush 21B and another second roller brush 22.

[0068] This invention, by setting the first roller brush 21 to include a first sub-roller brush 21A and a second sub-roller brush 21B, allows the first sub-roller brush 21A and the second sub-roller brush 21B to be driven by the first transmission component 13A and the second transmission component 13B respectively. The walking components 12 located on both sides of the body 11 can drive the first sub-roller brush 21A and the second sub-roller brush 21B to rotate independently, which can avoid interference caused by the different transmission ratios of the drive motors of the walking components 12 on both sides. This also makes it easier for the cleaning robot 100 to carry the roller brush component 20 for turning during the movement.

[0069] In a specific embodiment, the two transmission components 13 are a first transmission component 13A and a second transmission component 13B, respectively. The walking component 12 includes a first walking component 12A and a second walking component 12B, which are respectively disposed on opposite sides of the machine body 11. The first transmission component 13A is connected to the first walking component 12A, and the second transmission component 13B is connected to the second walking component 12B. It should be noted that the width of the machine body 10 mentioned above also refers to the maximum width distance between the first walking component 12A and the second walking component 12B.

[0070] In a specific embodiment, the first walking component 12A and the second walking component 12B may each be equipped with an independent drive motor, and the two drive motors drive the first walking component 12A and the second walking component 12B respectively. Therefore, the first walking component 12A is driven by the first transmission component 13A, so that the first walking component 12A, the first sub-roller brush 21A and the second roller brush 22 share a set of drive motors, and the second walking component 12B is driven by the second transmission component 13B, so that the second walking component 12B, the second sub-roller brush 21B and the other second roller brush 22 share a different set of drive motors.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the present utility model.
