TECHNICAL FIELD
[0001] The present application relates to the technical field of swimming pool cleaning, in particular to a swimming pool cleaning robot. STATE OF THE ART
[0002] Swimming pool cleaning is an important process for keeping pool water clean and safe. Regular pool cleaning not only ensures clear water and hygiene but also extends the lifespan of pool equipment. Swimming pools are typically cleaned primarily using manual or automatic cleaning devices. Due to the low efficiency of manual cleaning, automatic cleaning devices are becoming increasingly popular.
[0003] An automatic cleaning device introduces water containing impurities from the water inlet through the water-absorbing component into the filter component of the machine and cleans the swimming pool by filtration. The structural arrangement of the filter component, water-absorbing component, drive motor drive component, and transmission component is scattered at different positions and heights of the robot, and an inappropriate arrangement will result in a reduction in the cleaning ability of the robot.
[0004] For example, in one case, due to the inappropriate space arrangement between different components, the effective dust collection space of the filter component is limited. After the water-absorbing component is activated, the water flow is filtered through the filter component, which is easy to block the filtering position of the dust basket. Or, when the filter component is blocked, the front roller brush moves away from the cleaning surface, causing the front roller brush to deform or the entire machine to float, which affects the cleaning effect of the entire machine and increases the inconvenience to the user.in another case, due to the inappropriate space arrangement between the various components, when the automatic swimming pool cleaner is in the pool wall cleaning mode, the robot first moves from the pool bottom to the pool wall, in which case the front roller brush may be distorted before reaching the pool wall position, or in which, when the robot moves to the pool wall, the contact surface between the front roller brush and the wall is too small, the friction between the front roller brush and the pool wall is low, and the wall at the junction between the pool bottom and the pool wall cannot be cleaned, resulting in poor cleaning ability of the pool wall.; DISCLOSURE OF THE UTILITY MODEL
[0005] In order to solve the problem that the front roller brush of the automatic swimming pool cleaning robot in the above-mentioned prior art is prone to warping in advance before hitting the pool wall, which cannot meet the user's usage requirements for the overall cleaning ability in the pool wall cleaning mode, the present application provides a swimming pool cleaning robot, wherein the reasonable arrangement of each component can reduce the probability that the front roller brush is warped before hitting the pool wall in the pool wall cleaning mode, thereby effectively improving the overall cleaning effect of the robot.
[0006] To achieve the above-mentioned object, embodiments of the present application provide the following technical solutions: A first aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body having a front end and a rear end along a forward direction of the robot, the main body including a housing and a receiving space, the housing being provided with a water inlet communicating with the receiving space, the water inlet being arranged on the lower surface of the housing; a water-absorbing component; a filter component arranged in the receiving space, the filter component having a filter chamber, the filter component being provided with a dust opening, the dust opening being connected to the water inlet and the filter chamber, the water-absorbing component being used to suck in a water stream, so that the water stream containing impurities flows through the water inlet and the dust opening, is filtered by the filter chamber, and then discharged to the outside of the housing; a running component including a front running wheel, the front running wheel being rotatably provided at the front end; a drive component located proximate the front end, the drive component comprising an electric drive motor and a first output gear, the electric drive motor comprising a motor rotating shaft, the motor rotating shaft connected to the first output gear; a front roller brush rotatably mounted at the front end, the front roller brush being used to clean a surface to be cleaned, the front roller brush having a first state and a second state, in the first state the front roller brush being in contact with the pool wall and a pool floor, and in the second state the front roller brush being in contact only with the pool wall; a transmission component comprising at least one roller brush gear assembly; wherein the first output gear is connected to the front roller brush for driving via the roller brush gear assembly; wherein the robot includes a pool wall cleaning mode, wherein in the pool wall cleaning mode, the main body moves toward the pool wall, reducing the discharge volume of the water absorbing component or closing the water absorbing component until the drive component drives the front roller brush to change from the first state to the second state.
[0007] It should be further explained that in the present embodiment, the running component can drive the main body to move in a preset direction in the water of the swimming pool, where the water includes the underwater and the water surface. "Underwater" means that the swimming pool cleaning robot is completely submerged below the waterline, and "water surface" means that the swimming pool cleaning robot is at least partially exposed above the waterline. The water-absorbing component is used to provide suction to create a negative pressure at the water inlet position on the housing.After activating the water-absorbing component, the water flow containing impurities flows through the water inlet, the dust opening and the filter chamber under the action of suction force, then the dirt remains in the water in the filter chamber, and the water flow filtered by the filter chamber is discharged to the outside of the housing.
[0008] In the present embodiment, compared with the prior art, both the drive component and the front impeller are located close to the front end of the main body, and the front roller brush is drivingly connected to the first driven gear via the roller brush gear assembly. By limiting the position of the front roller brush, the electric drive motor, and the front impeller, and cooperating to drive each component with the gear component, the various components are compactly arranged at the front end of the main body, thereby increasing the space of the filter component while improving the quality at the position of the front roller brush. When activating the water-absorbing component, the filter space of the filter component can effectively reduce the probability of clogging of the filter component.According to this arrangement, in the pool wall cleaning mode, after the main body moves to the pool wall, the discharge volume of the water-absorbing component is reduced or closed, which can reduce the adsorption force at the water inlet, and thus it is actively controlled when the roller brush is raised relative to the pool bottom, assisting the front roller brush when switching from the first state to the second state, thereby increasing the contact area between the front roller brush and the surface to be cleaned, and thus further improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom when switching between the pool wall and the pool bottom.
[0009] A second aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body having a front end and a rear end along a forward direction of the robot, the main body having a housing and a receiving space, the housing being provided with a water inlet communicating with the receiving space, the water inlet being arranged on a lower surface of the housing; a water-absorbing component used to suck the water flow at the water inlet into the receiving space and then release it to the outside of the housing; a running component including a front running wheel, the front running wheel being rotatably provided at the front end; a drive component located proximate the front end, the drive component comprising an electric drive motor and a first output gear, the electric drive motor comprising a motor rotating shaft, the motor rotating shaft connected to the first output gear; a front roller brush rotatably mounted at the front end, the front roller brush being used to clean a surface to be cleaned, the front roller brush having a first state and a second state, in the first state the front roller brush being in contact with the pool wall and a pool floor, and in the second state the front roller brush being in contact only with the pool wall; a transmission component comprising at least one roller brush gear assembly; wherein the first output gear is connected to the front roller brush for driving via the roller brush gear assembly; wherein the robot includes a pool wall cleaning mode, wherein in the pool wall cleaning mode, the main body moves toward the pool wall, reducing the discharge volume of the water absorbing component or closing the water absorbing component until the drive component drives the front roller brush to change from the first state to the second state.
[0010] In the present embodiment, both the drive component and the front impeller are located near the front end of the main body, and the front roller brush is drivingly connected to the first driven gear via the roller brush gear assembly. By limiting the position of the front roller brush, the electric drive motor, and the front impeller, and cooperating to drive each component with the gear component, the various components are compactly arranged at the front end of the main body, thereby increasing the space of the filter component while improving the quality at the position of the front roller brush. When the water-absorbing component sucks the water flow and allows the water flow to flow through the water inlet and the receiving space before the water flow is discharged, a negative pressure is generated at the water inlet of the swimming pool cleaning robot.In this way, in the pool wall cleaning mode, after the main body moves to the pool wall, the discharge volume of the water-absorbing component is reduced or closed, which can reduce the negative pressure at the water inlet, thereby reducing the adsorption force of the swimming pool cleaning robot on the pool bottom or pool wall, and thus the swimming pool cleaning robot will actively control when the roller brush is lifted relative to the pool bottom, effectively assisting the front roller brush when switching from the first state to the second state, thereby increasing the contact area between the front roller brush and the surface to be cleaned, which can better clean the dead area between the pool bottom and the pool wall, thereby further improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom when switching between the pool wall and the pool bottom.
[0011] A third aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body having a front end and a rear end, and wherein the main body is provided with a detection component, wherein the detection component is used to detect environmental information, wherein the environmental information includes wall information of the pool wall, wherein in the horizontal direction the length of the swimming pool cleaning robot is L1, wherein in the vertical direction the width of the swimming pool cleaning robot is W1; a running component including a front running wheel provided near the front end; a drive component located proximate the front end, the drive component comprising an electric drive motor and a first output gear, the electric drive motor comprising a motor rotating shaft, the motor rotating shaft connected to the first output gear; a transmission component comprising a roller brush transmission assembly; a front roller brush rotatably disposed at the front end, the front roller brush component being used to clean a surface to be cleaned, the first output gear being connected to the front roller brush for driving via the roller brush gear assembly; The swimming pool cleaning robot includes a pool wall cleaning mode, wherein the main body moves toward the pool wall in the pool wall cleaning mode. When the pool wall is a first wall surface and the robot cannot move further toward the waterline along the first wall surface, the front impeller and the front roller brush are moved to a side facing away from the first wall surface. When the pool wall is a second wall surface, the front impeller and the front roller brush continue to move toward the waterline along the second wall surface until the robot reaches the waterline. The first wall surface represents a concave arcuate surface along the forward direction of the robot. The first wall surface has an inlet opening, the vertical diameter of the inlet opening having a maximum value of L2, and the maximum horizontal diameter of the inlet opening being W2.where L2 > L1 and W2 > W1, the second wall surface being a vertical wall.,
[0012] It should be further explained that in the present embodiment, the sensing component is used to collect environmental information in the swimming pool, and the swimming pool cleaning robot collects environmental information via the sensing component and adjusts the movement mode and the cleaning mode of the main body.In the present embodiment, after the sensing component acquires the surrounding information, the electric drive motor and the front impeller are both located near the front end of the main body, the front impeller is drivingly connected to the first driven gear via the impeller gear assembly, and the front roller brush is drivingly connected to the first driven gear via the roller brush gear assembly. By limiting the positions of the front roller brush, the electric drive motor, and the front impeller, and cooperating to drive each component with the gear component, the various components are compactly arranged at the front end of the main body, and the quality at the front roller brush position can be improved compared to other positions of the swimming pool cleaning robot.After this setting, in the pool wall cleaning mode, the robot can no longer move toward the waterline along the first wall surface after the main body moves toward the pool wall. When the pool wall is the first wall surface, the front impeller and front roller brush move sideways away from the first wall surface to increase the contact area between the front roller brush and the pool wall. This allows the transition between the first wall surface and the pool floor to be cleaned while effectively reducing the energy consumption of the cleaning robot.When the pool wall is the second wall surface, that is, when the pool wall is a vertical wall, the discharge volume of the water-absorbing component is reduced or closed, which can reduce the adsorption force at the water inlet, and thus it is actively controlled when the roller brush is raised relative to the pool bottom, assisting the front roller brush when switching from the first state to the second state, thereby increasing the contact area between the front roller brush and the surface to be cleaned, and thus further improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom when switching between the pool wall and the pool bottom.
[0013] A fourth aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body having a front end and a rear end along a forward direction of the robot; a running component including a front running wheel located near the front end; a drive component located proximate the front end, the drive component comprising an electric drive motor and a first output gear, the electric drive motor comprising a motor rotating shaft, the motor rotating shaft connected to the first output gear; wherein in the vertical direction the axis of rotation of the front idler wheel lies in the first plane, wherein the underside of the front idler wheel lies in a second plane, wherein the axis of rotation of the first output gear lies between the first plane and the second plane; a transmission component comprising an impeller-gear assembly; a front roller brush which is rotatably arranged at the front end and is used for cleaning a surface to be cleaned, wherein the first output gear is connected to the front roller brush for driving via the roller brush gear assembly, wherein the connecting lines between the rotation center of the first output gear, the rotation center of the front idler gear and the rotation center of the front roller brush form three angles, wherein the angle with the rotation center of the front idler gear as the vertex is a first angle β, where β < 150°.
[0014] It should be further explained that in the present embodiment, the electric drive motor and the front idler gear are both located close to the front end of the main body, the front idler gear is drivingly connected to the first driven gear via the idler gear assembly, and the front roller brush is drivingly connected to the first driven gear via the roller brush gear assembly, so that the first angle β < 150 °, and thus the front roller brush, the electric drive motor, the front idler gear, and the first driven gear are all concentrated at the front end of the main body and near the bottom of the main body, which improves the overall compact arrangement of various components at the position of the front roller brush and at the front end of the main body.After this setting, when the robot is in the pool bottom cleaning mode or the pool wall cleaning mode, it can effectively prevent the front roller brush from lifting relative to the pool bottom in the event of an accident, which helps to increase the contact area between the front roller brush and the surface to be cleaned and improve the cleaning effect of the swimming pool cleaning robot in the dead area between the pool bottom and the pool wall when switching between the pool bottom and the pool wall.
[0015] In the swimming pool cleaning device provided by embodiments of the present application, the swimming pool cleaning robot further comprises a water-absorbing component, wherein in the pool wall cleaning mode, when the front roller brush only abuts the pool wall, the water-absorbing component is started or the discharge volume of the water-absorbing component is increased.

[0017] In the swimming pool cleaning device provided by embodiments of the present application, the gear component also includes an impeller gear assembly, wherein the first output gear is drivingly connected to the front impeller via the impeller gear assembly, wherein the roller brush gear assembly includes an internal gear, wherein the first output gear is located inside the front impeller and the internal gear is arranged on the inner wall of the front impeller, wherein the first output gear is drivingly meshing with the internal gear.
[0018] It should be further explained that the first driven gear is located inside the front idler gear and drivingly meshes with the internal gear to drive the front idler gear to rotate relative to the main body, drive the main body to move relative to it, and further limit the position of the first driven gear, whereby the electric drive motor and the first driven gear are further concentrated on one side of the front idler gear, thereby improving the space integration effect at the front end of the main body.
[0019] In the swimming pool cleaning device provided by embodiments of the present application, the roller brush gear assembly includes a first external gear, a second external gear, and a roller brush drive gear, wherein the first external gear is disposed inside the front impeller and the front impeller rotates coaxially and in the same direction, wherein the outer diameter of the first external gear is smaller than the inner diameter of the internal gear, wherein the roller brush drive gear is disposed on the rotating shaft of the front roller brush, wherein the second external gear is disposed between the first external gear and the roller brush drive gear, wherein the second external gear drivingly meshes with the first external gear and the roller brush drive gear.
[0020] It should be further explained that the first external gear, the second external gear, and the roller brush drive gear are all concentrated at the front end of the main body, so that the rotation direction of the first driven gear is consistent with the rotation direction of the front roller brush and the front idler gear, that is, the first driven gear, the front roller brush, and the front idler gear rotate clockwise or counterclockwise at the same time, which facilitates the control of the rotation direction of the front roller brush and at the same time facilitates the calculation of the rotation direction of the front idler gear by the robot to measure the running performance of the robot.
[0021] In the swimming pool cleaning device provided by embodiments of the present application, the rotation center of the front impeller is located in the first plane in the vertical direction, the bottom of the front impeller is located in a second plane, the rotation center of the front impeller, the rotation center of the second external gear, and the rotation center of the roller brush drive gear are all located between the first plane and the second plane, the rotation center of the first driven gear is located in the first plane, or the rotation center of the first driven gear is located between the first plane and the second plane.
[0022] It should be further explained that by moving the front idler gear, the second external gear, the first driven gear, and the roller brush drive gear close to the second plane, the stability at the ground-facing position of the front end of the main body is further increased to further prevent the warping of the front roller brush.
[0023] In the swimming pool cleaning device provided by embodiments of the present application, the rotation center of the front impeller is located in the first plane in the vertical direction, the bottom of the front impeller is located in a second plane, the rotation center of the front impeller, the rotation center of the second external gear, and the rotation center of the roller brush drive gear are all located between the first plane and the second plane, and the rotation axis of the first driven gear is located above the first plane along the vertical upward direction.
[0024] It should be further explained that in the present embodiment, the front idler gear, the second external gear, and the roller brush drive gear are close to the second plane, so that the first driven gear is positioned above the first plane and is drivingly connected to the internal gear, so that the first driven gear, the front roller brush, and the front idler gear rotate clockwise or counterclockwise at the same time, thereby facilitating the control of the rotation direction of the front roller brush and, at the same time, the calculation of the rotation direction of the front idler gear by the robot to measure the running performance of the robot.
[0025] In the swimming pool cleaning device provided by embodiments of the present application, the first external gear and the front impeller are formed integrally.
[0026] It should be further explained that in the present embodiment, an internal gear is provided on the inner wall of the front idler gear, and a first external gear is provided at the rotation center of the front idler gear. By the driving connection between the first external gear and the internal gear, when the first driven gear drives the internal gear to rotate, synchronous rotation of the first external gear and the front idler gear can be realized, which improves the stability of the transmission component during the driving operation.
[0027] In the swimming pool cleaning device provided by embodiments of the present application, the first external gear is detachably connected to the front impeller, wherein the roller brush gear component also comprises a second output gear, wherein the second output gear and the first output gear are provided spaced apart along an axial direction of the rotational axis of the electric drive motor on the motor rotation shaft, wherein the first output gear and the second output gear rotate in the same direction, wherein the second output gear is drivingly connected to the first external gear.
[0028] It should be further explained that in the present embodiment, the front idler gear is detachably connected to the first external gear, wherein, for example, when the front idler gear needs to be serviced, the first external gear does not need to be disassembled, which facilitates maintenance of the running component, wherein the driving connection between the second driven gear and the first external gear makes the driven gear, the front roller brush, and the front idler gear rotate clockwise or counterclockwise at the same time, thereby facilitating the control of the rotation direction of the front roller brush and, at the same time, the calculation of the rotation direction of the front idler gear by the robot to measure the running performance of the robot.

[0031] In the swimming pool cleaning device provided by embodiments of the present application, the curvature of the first wall surface gradually increases along the vertical upward direction.
[0032] In the present embodiment, since the curvature of the first wall surface gradually increases, the front roller brush gradually moves away from the first wall surface, thereby reducing the friction between the front roller brush and the first wall surface. After identifying the condition of the first pool wall, the sensing component can control the front impeller and the front roller brush to move to one side away from the first wall surface.
[0033] In the present embodiment, the swimming pool cleaning device includes a main body, a water-absorbing component, a filter component, a running component, a transmission component, and a front roller brush, wherein the running component includes a front impeller and the drive component, and wherein the front impeller is arranged near the front end of the main body, wherein the front roller brush has a first state and a second state, wherein when the main body moves to the pool wall in the pool wall cleaning mode of the robot, the discharge volume of the water-absorbing component is reduced or turned off until the running component drives the front roller brush to switch from the first state to the second state.Compared with the existing technology, the swimming pool cleaning device provided by the present application can increase the effective filtering space of the filter component and prevent the front roller brush from warping before it hits the pool wall, whereby, when the swimming pool cleaning robot moves from the pool bottom to the pool wall, for example, the contact area between the front roller brush and the surface to be cleaned is increased, thereby improving the overall cleaning effect of the swimming pool cleaning robot.

[0035] In order to clarify the purpose, technical solutions, and advantages of the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model are described clearly and completely below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the embodiments are some of the embodiments of the present utility model, not all of the embodiments. All other embodiments that a person skilled in the art can derive from the embodiments in the present utility model without creative effort are within the scope of the present utility model.
[0036] In order to reduce the probability that the front roller brush 15 tilts before hitting the pool wall 400 in the pool wall cleaning mode 400 of the swimming pool cleaning robot, the effective space of the filter chamber 121 of the filter component 12 is increased and clogging of the filter component 12 is avoided, thereby increasing the contact area between the front roller brush 15 and the surface to be cleaned, thereby improving the cleaning effect between the front roller brush 15 and the pool wall 400 or between the pool wall 400 and an edge position on the pool bottom 500.
[0037] When the pool cleaning robot is in operation, the front roller brush 15 swirls up the dirt on the surface to be cleaned. As the rotation of the front roller brush 15 moves the water toward the filter component 12, the water-absorbing component 11 generates suction, forcing the contaminant-containing water stream through the water inlet 131 and the dust opening 122, filtered by the filter chamber 121, and then discharged to the outside of the housing 103.During this process, if the filter chamber 121 of the filter component 12 is clogged, it may not meet the demand for filtering impurities in the water and may result in the water absorbing component 11 being unable to generate negative pressure at the water inlet 131, whereby the swimming pool cleaning robot cannot clean the pool wall 400, or in the pool wall 400 cleaning mode, the robot slips off the pool wall 400, resulting in poor cleaning effect. Example 1
[0038] A first aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body 10 having a front end 101 and a rear end 102 along a forward direction of the robot, the main body 10 having a housing 103 and a receiving space 104, the housing 103 being provided with a water inlet 131 communicating with the receiving space 104, the water inlet 131 being provided on the lower surface of the housing 103; a water-absorbing component 11; a filter component 12 arranged in the receiving space 104 and near the rear end 102 of the housing 103, the filter component 12 having a filter chamber 121, the filter component 12 being provided with a dust opening 122, the dust opening 122 being connected to the water inlet 131 and the filter chamber 121, the water-absorbing component 11 being used to suck in a water stream, so that the water stream containing impurities flows through the water inlet 131 and the dust opening 122, is filtered by the filter chamber 121, and then discharged to the outside of the housing 103; a running component 13 including a front running wheel 1302, the front running wheel 1302 being rotatably provided on the front end 101; a drive component located near the front end 101, the drive component comprising an electric drive motor 1301 and a first output gear 1312, the electric drive motor 1301 comprising a motor rotating shaft 1311, the motor rotating shaft 1311 being connected to the first output gear 1312; a front roller brush 15 which is rotatably arranged at the front end 101, wherein the front roller brush 15 is used for cleaning a surface to be cleaned, wherein the front roller brush has a first state 100 and a second state 200, wherein in the first state 100 the front roller brush 15 is in contact with the pool wall 400 and a pool floor 500, wherein in the second state 200 the front roller brush 15 is only in contact with the pool wall 400; a transmission component 14 comprising at least one roller brush gear assembly 142; wherein the first output gear 1312 is connected to the front roller brush 15 for driving via the roller brush gear assembly 142; wherein the robot includes a pool wall cleaning mode 400, wherein in the pool wall cleaning mode 400, the main body 10 moves toward the pool wall 400, reducing the discharge volume of the water absorbing component 11 or closing the water absorbing component 11 until the drive component drives the front roller brush 15 to change from the first state 100 to the second state 200.
[0039] In the present embodiment, the running component 13 can drive the main body 10 to move in a preset direction in the water of the swimming pool, where the water includes the underwater and the water surface, where "underwater" means that the swimming pool cleaning robot is completely submerged below the waterline 300, and "water surface" means that the swimming pool cleaning robot is at least partially exposed above the waterline 300. The water-absorbing component 11 is used to provide suction to create a negative pressure at the position of the water inlet 131 on the housing 103.After activating the water-absorbing component 11, the water flow containing impurities flows through the water inlet 131, the dust opening 122 and the filter chamber 121 under the action of the suction force, then the dirt remains in the water in the filter chamber 121, and the water flow filtered by the filter chamber 121 is discharged to the outside of the housing 103.In some embodiments, the housing 103 is provided with a water outlet 132, and the filtered water flow is discharged through the water outlet 132 to the outside of the housing 103. The water outlet 132 may be provided on the top of the housing 103 or at other locations on the housing 103. In this embodiment and other embodiments, the position of the water outlet 132 relative to the housing 103 is not limited, and a person skilled in the art can adjust the position of the drainage opening according to the actual usage conditions, all of which are within the scope of the embodiments of this application. Furthermore, the water-absorbing component 11 provides suction for the water flow from the water inlet 131 to the water outlet 132.
[0040] In the present embodiment, as shown in Fig. 1, Fig. 2 and Fig. 14, the electric drive motor 1301 and the front idler gear 1302 are both located near the front end 101 of the main body 10, the front idler gear 1302 is drivingly connected to the first output gear 1312 via the roller brush gear assembly 142, and the front roller brush 15 is drivingly connected to the first output gear 1312 via the idler gear assembly 141. By limiting the positions of the front roller brush 15, the electric drive motor 1301, and the front idler gear 1302, and by cooperating with the driving connection of the gear component 14, the various components are arranged compactly at the front end 101 of the main body 10, thereby increasing the space of the filter component 12 and simultaneously improving the quality at the position of the front roller brush 15.When activating the water-absorbing component 11, the filter space of the filter component 12 can effectively reduce the probability of clogging of the filter component 12.According to this arrangement, in the pool wall 400 cleaning mode, after the main body 10 moves toward the pool wall 400, the discharge volume of the water-absorbing component 11 is reduced or closed, which can reduce the adsorption force at the water inlet 131, and thus, it is actively controlled when the roller brush is raised relative to the pool bottom 500, assisting the front roller brush 15 in switching from the first state 100 to the second state 200, thereby increasing the contact area between the front roller brush 15 and the surface to be cleaned, and thus further improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom 500 when switching between the pool wall 400 and the pool bottom 500, and better cleaning the dead area between the pool bottom and the pool wall.
[0041] Furthermore, the filter component 12 is arranged near the rear end 102 of the main body 10, and the front roller brush 15 and the drive component are arranged near the front end 101 of the main body 10, thereby providing a larger space for the filter component 12 in the receiving space 104. In the following, the various states in which the swimming pool cleaning robot starts to climb the wall and clean the pool wall 400 in the pool wall cleaning mode 400 will be further introduced and explained in detail in the description with reference to the accompanying drawings.
[0042] As in Fig. 3, the front roller brush 15 is not in contact with the pool wall 400. In the present embodiment, the water-absorbing component 11 sucks the water flow into the water inlet 131 on the underside of the housing 103 and then discharges it through the water outlet 132 on the top of the housing 103. The drive component drives the front roller brush 15 to rotate relative to the main body 10. The front roller brush 15 stirs the water flow to one side of the water inlet 131. The dirt in the water, particularly on the surface of the pool floor 500, is rolled up by the front roller brush 15. A negative pressure is created at the water inlet 131 by the action of the water-absorbing component 11, and the discharge volume is larger at the water outlet 132. As shown in Fig. As shown in Figure 2, the dirt in the water enters the filter chamber 121 after passing through the water inlet 131 and the dust port 122. The impurities in the water are retained in the downstream filter chamber 121, and the filtered water flow is discharged through the drainage port. Since the transmission component 14 and the drive component are located close to the front end 101 of the main body 10 as mentioned above, the effective filtering area of the filter chamber 121 is larger and less likely to be blocked, thereby increasing the impurity holding space.
[0043] As in Fig. 4, the front roller brush 15 is in contact with the pool wall 400 and the pool floor 500, that is, the front roller brush 15 is in the first state 100 at this time. The difference from the Fig. 3 is that at this time, the discharge volume of the water-absorbing component 11 decreases, and the negative pressure at the water inlet 131 decreases, and the front impeller 1302 and the front roller brush 15 continue to rotate. Furthermore, the front roller brush 15 can clean up to the junction between the pool wall 400 and the pool floor 500, i.e., the edge area of the pool floor 500. In this state, friction exists between the front roller brush 15 and the pool wall 400. When the drive component drives the front roller brush 15 via the roller brush gear assembly 142 so that it moves further toward the pool wall 400, the front roller brush 15 can be slightly lifted relative to the pool floor 500 and moves along the pool wall 400 toward the waterline 300.
[0044] As in Fig. 5, there is a difference between this state and the one in Fig. 4 is that the water-absorbing component 11 is closed at this time, that is, the discharge volume of the water-absorbing component 11 is zero. When the drive component drives the front roller brush 15 via the roller brush gear assembly 142 to move further toward the pool wall 400, the swimming pool cleaning robot can be used in comparison with the state shown in Fig. 4, the front roller brush 15 can be lifted more easily relative to the pool floor 500. The person skilled in the art will adjust the working state of the water-absorbing component 11 as shown in Fig. 4 or Fig. 5, in the cleaning mode of the pool wall 400, the system adapts to different swimming pool conditions. For example, if there are many impurities at the edge position between the pool wall 400 and the pool floor 500, the state of the water-absorbing component 11 reduces the discharge volume, as shown in Fig. 4, but the discharge volume is not zero. In another situation, when the pool wall 400 has a complex shape and it is difficult for the swimming pool robot to climb the wall, the state of the water-absorbing component 11 of the swimming pool cleaning robot is as shown in Fig. 5 shown, whereby the water-absorbing component 11 is closed.
[0045] As in Fig. 6, there is a difference between this state and the ones shown in the Fig. 4 and Fig. 5 is that at this time the front roller brush 15 only touches the pool wall 400, that is, the front roller brush 15 is in the second state 200. In the states shown in the Fig. 4 and Fig. 5, the roller brush can change from the first state 100 to the second state 200 after the drive component continues to drive the front roller brush 15 to rotate, wherein the front roller brush 15 rotates relative to the pool wall 400 and stirs the dirt on the pool wall 400 to move it toward the water inlet 131, thereby cleaning the pool wall 400.
[0046] Furthermore, in one embodiment, the swimming pool cleaning robot also comprises a water-absorbing component 11, wherein in the cleaning mode of the pool wall 400, when the front roller brush 15 only rests against the pool wall 400, the water-absorbing component 11 is started or the discharge volume of the water-absorbing component 11 is increased.
[0047] In the present embodiment, in the cleaning mode of the pool wall 400, when the front roller brush 15 is only in contact with the pool wall 400, the drainage volume of the water-absorbing component 11 is increased and the suction force of the bottom of the entire robot is increased, and the contact area between the brush 15 and the pool wall 400 is further increased, thereby increasing the friction between the front roller brush 15 and the pool wall 400, thereby improving the cleaning effect of the front roller brush 15 on the pool wall 400 and improving the stability of the movement of the main body 10 on the pool wall 400, while preventing the robot from slipping from the pool wall 400 to the pool bottom 500. Example 2
[0048] A second aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body 10 having a front end 101 and a rear end 102 along a forward direction of the robot, the main body 10 having a housing 103 and a receiving space 104, the housing 103 being provided with a water inlet 131 communicating with the receiving space 104, the water inlet 131 being arranged on a lower surface of the housing 103; a water-absorbing component 11 used to suck the water flow at the water inlet 131 into the receiving space 104 and then discharge it to the outside of the housing 103; a running component 13 including a front running wheel 1302, the front running wheel 1302 being rotatably provided on the front end 101; a drive component located near the front end 101, the drive component comprising an electric drive motor 1301 and a first output gear 1312, the electric drive motor 1301 comprising a motor rotating shaft 1311, the motor rotating shaft 1311 being connected to the first output gear 1312; a front roller brush 15 which is rotatably arranged at the front end 101, wherein the front roller brush 15 is used for cleaning a surface to be cleaned, wherein the front roller brush has a first state 100 and a second state 200, wherein in the first state 100 the front roller brush 15 is in contact with the pool wall 400 and a pool floor 500, wherein in the second state 200 the front roller brush 15 is only in contact with the pool wall 400; a transmission component 14 comprising at least one roller brush gear assembly 142; wherein the first output gear 1312 is connected to the front roller brush 15 for driving via the roller brush gear assembly 142; wherein the robot includes a pool wall cleaning mode 400, wherein in the pool wall cleaning mode 400, the main body 10 moves toward the pool wall 400, reducing the discharge volume of the water absorbing component 11 or closing the water absorbing component 11 until the drive component drives the front roller brush 15 to change from the first state 100 to the second state 200.
[0049] Unlike the above-mentioned Embodiment 1, in Embodiment 2, the function of the water-absorbing component 11 is redefined. The water-absorbing component 11 is used only to suck the water flow at the water inlet 131 into the receiving space 104 and then discharge it to the outside of the housing 103. The technology related to the filter component 12 is not introduced. For related technologies, reference may be made to the previous embodiment or other existing technologies. In the present embodiment, there will be no excessive description related to the filter component 12.In the present embodiment, the relevant states and functions of the swimming pool cleaning robot in the pool wall cleaning mode 400 will be described with reference to the above embodiments, and only the advantageous effects of the present embodiment compared with the prior art will be briefly described below.
[0050] In the present embodiment, compared to the prior art, both the drive component and the front idler gear 1302 are located close to the front end 101 of the main body 10, and the front roller brush 15 is drivingly connected to the first driven gear 1312 via the roller brush gear assembly 142. By limiting the positions of the front roller brush 15, the electric drive motor 1301, and the front idler gear 1302, and cooperating to drive each component with the gear component 14, the various components are arranged compactly at the front end 101 of the main body 10, thereby increasing the space of the filter component 12 and simultaneously improving the quality at the position of the front roller brush 15.After the water-absorbing component 11 has performed suction, a negative pressure is created at the water inlet 131 of the swimming pool cleaning robot by the process in which the water flow flows through the water inlet 131 and the receiving space 104 and is then discharged.In this way, in the pool wall cleaning mode 400, after the main body 10 moves toward the pool wall 400, the discharge volume of the water-absorbing component 11 is reduced or closed, which can reduce the negative pressure at the water inlet 131, thereby reducing the adsorption force of the swimming pool cleaning robot on the pool bottom 500 or the pool wall 400. Thus, the swimming pool cleaning robot will actively control when the roller brush is raised relative to the pool bottom 500, effectively assisting the front roller brush 15 when switching from the first state 100 to the second state 200, thereby increasing the contact area between the front roller brush 15 and the surface to be cleaned, and thus further improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom 500 when switching between the pool wall 400 and the pool bottom 500. Example 3
[0051] A third aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body 10 having a front end 101 and a rear end 102, and wherein the main body 10 is provided with a detection component 105, wherein the detection component 105 is used to detect environmental information, wherein the environmental information includes wall information of the pool wall 400, wherein in the horizontal direction the length of the swimming pool cleaning robot is L1, wherein in the vertical direction the width of the swimming pool cleaning robot is W1; a running component 13 including a front running wheel 1302 provided near the front end 101; a drive component located near the front end 101, the drive component comprising an electric drive motor 1301 and a first output gear 1312, the electric drive motor 1301 comprising a motor rotating shaft 1311, the motor rotating shaft 1311 being connected to the first output gear 1312; a gear component 14 including a roller brush gear assembly 142; a front roller brush 15 rotatably mounted on the front end 101, the front roller brush 15 being used to clean a surface to be cleaned, the first output gear 1312 being connected to the front roller brush (15) for driving via the roller brush gear assembly 142; wherein the swimming pool cleaning robot comprises a cleaning mode of the pool wall 400, wherein the main body 10 moves towards the pool wall 400 in the cleaning mode of the pool wall 400, wherein, when the pool wall 400 is a first wall surface 16 and the robot cannot move further along the first wall surface 16 in the direction of the water line 300, the front impeller 1302 and the front roller brush 15 are moved to a side facing away from the first wall surface 16, wherein, when the pool wall 400 is a second wall surface 17, the front impeller 1302 and the front roller brush 15 move further along the second wall surface 17 in the direction of the water line 300 until the robot reaches the water line 300, wherein the first wall surface 16 represents a concave arcuate surface along the forward direction of the robot, wherein the first wall surface 16 has an inlet opening 161, wherein the vertical Diameter of the inlet opening 161 has a maximum value of L2,wherein the maximum horizontal diameter of the inlet opening 161 is W2, where L2 > L1 and W2 > W1, wherein the second wall surface 17 is a vertical wall.,
[0052] The difference between Embodiment 3 and Embodiment 2 above is that Embodiment 3 does not emphasize the influence of the water-absorbing component 11 on the cleaning state of the swimming pool cleaning robot, but the main body 10 is provided with a sensing component 105. The environmental information in the swimming pool can be sensed by the sensing component 105, which includes the information of the pool wall 400. The sensing component 105 is used to sense and control the cleaning mode of the swimming pool cleaning robot to achieve intelligent cleaning and further reduce energy consumption.
[0053] For example, the detection component 105 includes a distance sensor, an image sensor, a line laser, an IMU or an odometer and the like provided on the main body 10, wherein the moving posture of the robot is detected via the IMU, or the traveling performance of the robot is detected via the odometer to determine the traveling distance or displacement position of the swimming pool robot.
[0054] It should be further explained that in the present embodiment, the sensing component 105 is used to collect environmental information in the swimming pool. The swimming pool cleaning robot collects environmental information via the sensing component 105 and adjusts the movement mode and cleaning mode of the main body 10. In the present embodiment, after the sensing component 105 has sensed the environmental information, the electric drive motor 1301 and the front impeller 1302 are both located near the front end 101 of the main body 10, the front impeller 1302 is drivingly connected to the first driven gear 1312 via the impeller gear assembly 141, and the front roller brush 15 is drivingly connected to the first driven gear 1312 via the roller brush gear assembly 142.
[0055] By limiting the position of the front roller brush 15, the electric drive motor 1301, and the front impeller 1302, and cooperating to drive each component with the transmission component 14, the various components are arranged compactly at the front end 101 of the main body 10, and the quality at the position of the front roller brush 15 can be improved compared to other positions of the swimming pool cleaning robot.
[0056] Furthermore, in the pool wall 400 cleaning mode, the robot cannot continue to move toward the waterline 300 along the first wall surface 16 after the main body 10 moves toward the pool wall 400 when the pool wall 400 is the first wall surface 16, and the front impeller 1302 and the front roller brush 15 move sideways away from the first wall surface 16 to increase the contact area between the front roller brush 15 and the pool wall 400. In this way, the transition between the first wall surface 16 and the pool floor 500 can be cleaned, while effectively reducing the energy consumption of the cleaning robot.
[0057] Furthermore, in the cleaning mode of the pool wall 400, after the main body 10 moves toward the pool wall 400, when the pool wall 400 is the second wall surface 17, that is, when the pool wall 400 is a vertical wall surface, the drainage volume of the water-absorbing component 11 is reduced or closed, whereby the adsorption force at the position of the water inlet 131 can be reduced, and thus, it is actively controlled when the roller brush is raised relative to the pool bottom 500, assisting the front roller brush 15 in switching from the first state 100 to the second state 200, thereby increasing the contact area between the front roller brush 15 and the surface to be cleaned, and thus further improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom 500 when switching between the pool wall 400 and the pool bottom 500.
[0058] Hereinafter, in Embodiment 3, when the swimming pool cleaning robot executes the pool wall cleaning mode 400, the different cleaning states of the first wall surface 16 and the second wall surface 17 will be described in detail.
[0059] As in Fig. 7 is a schematic diagram of the state of the front roller brush 15 of the swimming pool cleaning device when it is in contact with both the first wall surface 16 and the pool floor 500, wherein the running component 13 continues to drive the main body 10 to move toward the first wall surface 16, the front roller brush 15 is in contact with the first wall surface 16, and the detection component 105 detects the information of the pool wall 400 in real time, such as the inclination angle information of the pool wall 400 relative to the pool floor 500 or the displacement distance of the main body 10 in the pool wall 400, the front roller brush 15 rotates at the junction between the pool floor 500 and the first wall surface 16, driven by the friction of the front roller brush 15, the junction between the first wall surface 16 and the pool floor 500 can be better cleaned. When the front roller brush 15 is moved to the Fig. 8 and the front roller brush 15 only touches the first wall surface 16, the main body 10 gradually moves from the inlet opening 161 formed on the first wall surface 16 to the inwardly concave arcuate portion of the first wall surface 16. Since L2 > L1 and W2 > W1, as shown in Fig. As shown in Figure 9, the swimming pool cleaning robot cannot move further to the water line 300 after moving along the first wall surface 16 to the water line 300 by the displacement distance, and the swimming pool cleaning robot moves sideways away from the first wall surface 16. For example, the front roller brush 15 moves in a vertical downward direction along the first wall surface 16 and gradually moves until the front roller brush 15 is completely out of contact with the first wall surface 16. In this way, even if the swimming pool cleaning robot needs to clean the first wall surface 16 in the pool wall 400 cleaning mode, it can ensure that at least part of the first wall surface 16 and the junction between the first wall surface 16 and the pool floor 500 are well cleaned.
[0060] Moreover, in the swimming pool cleaning device provided by embodiments of the present application, the first wall surface 16 has a top surface in the vertical direction, the top surface being located within the inlet opening 161, and the distance between the top surface and the horizontal plane of the pool floor 500 being L3, where L3>L2.
[0061] In the present embodiment, in the swimming pool cleaning robot, when L3>L2, the arcuate surface between the top of the first wall surface 16 and the top of the inlet opening 161 cannot be cleaned, and the front impeller 1302 and the front roller brush 15 move away from the first wall surface 16.
[0062] In the swimming pool cleaning device provided by embodiments of the present application, the curvature of the first wall surface 16 gradually increases along the vertical upward direction.
[0063] In the present embodiment, since the curvature of the first wall surface 16 gradually increases, the front roller brush 15 gradually moves away from the first wall surface 16, thereby reducing the friction between the front roller brush 15 and the first wall surface 16. After identifying the condition of the first pool wall 400, the sensing component 105 can control the front idler wheel 1302 and the front roller brush 15 to move to one side away from the first wall surface 16.
[0064] As in Fig. 10, the difference to the one shown in the Fig. 7 to 9 in that the pool wall 400 at this time is the second wall surface 17, the second wall surface 17 is a vertical wall and the front roller brush 15 is in contact with the second wall surface 17, the drive component drives the front roller brush 15 to gradually move from the pool bottom 500 along the second wall surface 17 to the water line 300 and thereby clean the second wall surface 17. Example 4
[0065] A fourth aspect of the embodiment of the present application provides a swimming pool cleaning robot that can move in water for cleaning, the swimming pool cleaning robot comprising: a main body 10 having a front end 101 and a rear end 102 along a forward direction of the robot; a running component 13 including a front running wheel 1302 located near the front end 101; a drive component located near the front end 101, the drive component comprising an electric drive motor 1301 and a first output gear 1312, the electric drive motor 1301 comprising a motor rotating shaft 1311, the motor rotating shaft 1311 being connected to the first output gear 1312; wherein in the vertical direction the axis of rotation of the front idler gear 1302 lies in a first plane 18, wherein the underside of the front idler gear 1302 lies in a second plane 19, wherein the axis of rotation of the first output gear 1312 lies between the first plane 18 and the second plane 19; a transmission component 14 comprising an impeller gear assembly 141; a front roller brush 15 which is rotatably arranged at the front end 101 and is used for cleaning a surface to be cleaned, wherein the first output gear 1312 is connected to the front roller brush 15 for driving via the roller brush gear assembly 142, wherein the connecting lines between the rotation center of the first output gear 1312, the rotation center of the front idler gear 1302 and the rotation center of the front roller brush 15 form three angles, wherein the angle with the rotation center of the front idler gear 1302 as the vertex is a first angle β, where β < 150°.
[0066] The difference between Embodiment 4 and Embodiment 1 is that the influence of the water-absorbing component 11 and the filter component 12 on the swimming pool cleaning robot is not emphasized in Embodiment 4. For related technologies, reference can be made to Embodiment 1 or other existing technologies, and in the present embodiment, there will not be too much description related to the filter component 12 and the water-absorbing component 11. In the present embodiment, the relevant states and functions of the swimming pool cleaning robot in the pool wall cleaning mode 400 will be described with reference to the above embodiments, and only the advantageous effects of the present embodiment compared to the prior art will be briefly described below.
[0067] As in the Fig. 11 and Fig. 12, it should be further explained that in the present embodiment, the electric drive motor 1301 and the front idler gear 1302 are both located close to the front end 101 of the main body 10, the front idler gear 1302 being drivingly connected to the first output gear 1312 via the idler gear assembly 141, and the front roller brush 15 being drivingly connected to the first output gear 1312 via the roller brush gear assembly 142, so that the first angle β < 150°, and thus the front roller brush 15, the electric drive motor 1301, the front idler gear 1302 and the first output gear 1312 are all concentrated at the front end 101 of the main body 10 and close to the bottom of the main body 10, which ensures the overall compact arrangement of various components at the position of the front Roller brush 15 and at the front end 101 of the main body 10.After this setting, when the robot is in the pool bottom cleaning mode 500 or the pool wall cleaning mode 400, it can effectively prevent the front roller brush 15 from lifting relative to the pool bottom 500 in the event of an accident, which contributes to increasing the contact area between the front roller brush 15 and the surface to be cleaned and improving the cleaning effect of the swimming pool cleaning robot at the edge position of the pool bottom 500 when switching between the pool bottom 500 and the pool wall 400.
