Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pool cleaning, and in particular to a pool cleaning robot. BACKGROUND

[0002] Pool cleaning is an important process for maintaining the cleanliness and safety of swimming pool water. Regular pool cleaning not only ensures the clarity and hygiene of the water, but also prolongs the service life of the pool equipment. The cleaning of a swimming pool usually relies on manual cleaning or automatic cleaning equipment. Due to the low efficiency of manual cleaning, automatic cleaning equipment is increasingly popular.

[0003] The automatic cleaning equipment guides the water containing impurities from the water inlet to the filtering assembly of the machine through the water suction assembly, and cleans the swimming pool through filtering treatment. The structural layout of the filtering assembly, the water suction assembly, the driving motor driving assembly and the transmission assembly is dispersed at various positions and heights of the robot, and the unreasonable layout can cause the cleaning ability of the robot to decrease.

[0004] For example, in one case, due to the unreasonable spatial layout between the various components, the effective dust collection space of the filtering assembly is limited. After the water suction assembly is started, the water flows through the filtering assembly for filtering, and the filtering position of the garbage basket is easily blocked. Or if the filtering assembly is blocked, the front roller brush will be away from the cleaning surface, causing the front roller brush to tilt or the entire machine to float, affecting the cleaning effect of the entire machine and increasing the inconvenience of the user; in another case, due to the unreasonable spatial layout between the various components, when the automatic pool cleaning equipment is in the pool wall cleaning mode, the robot will first move from the pool bottom to the pool wall direction, and the front roller brush can tilt before reaching the pool wall position, or when the robot moves to the pool wall position, the front roller brush has a small area of adhesion with the wall, and the friction between the front roller brush and the pool wall is small, so the wall between the pool bottom and the pool wall cannot be cleaned, resulting in poor pool wall cleaning ability. CONTENT OF THE INVENTION

[0005] In order to solve the above-mentioned problem that the front roller brush of the automatic pool cleaning robot tilts early when encountering the pool wall in the prior art, and cannot meet the user's demand for the overall cleaning ability in the pool wall cleaning mode, the present application provides a pool cleaning robot, which can reduce the probability of the front roller brush tilting when encountering the pool wall in the pool wall cleaning mode by reasonably arranging the various components, and effectively improve the overall cleaning effect of the robot.

[0006] To achieve the above-mentioned purpose, the embodiments of the present application provide the following technical solutions:

[0007] The first aspect of the embodiments of the present application provides a pool cleaning robot, which can move in water for cleaning. The pool cleaning robot comprises:

[0008] The main body has a front end and a rear end in the advancing direction of the robot, and has a housing and a receiving cavity. The housing is provided with a water inlet communicating with the receiving cavity, and the water inlet is arranged on the lower surface of the housing.

[0009] The water suction assembly is arranged in the receiving cavity.

[0010] The filter assembly is arranged in the receiving cavity, and has a filter cavity. The filter assembly is provided with a dust port communicating with the water inlet and the filter cavity. The water suction assembly is used to suck water flow, so that the water flow containing impurities is filtered through the filter cavity after passing through the water inlet and the dust port, and then discharged to the outside of the housing.

[0011] The walking assembly includes a front walking wheel rotatably arranged at the front end.

[0012] The driving assembly is close to the front end, and includes a driving motor and a first output gear. The driving motor includes a motor rotating shaft connected to the first output gear.

[0013] The front roller brush is rotatably arranged at the front end and is used to clean the surface to be cleaned. The front roller brush includes a first state and a second state. In the first state, the front roller brush abuts against the pool wall and the pool bottom. In the second state, the front roller brush only abuts against the pool wall.

[0014] The transmission assembly includes at least a roller brush transmission group. The first output gear is in transmission connection with the front roller brush through the roller brush transmission group.

[0015] The robot includes a pool wall cleaning mode. In the pool wall cleaning mode, the main body moves to the pool wall, the water suction assembly reduces the water discharge amount or is turned off, and the driving assembly drives the front roller brush to switch from the first state to the second state.

[0016] It should be further explained that in the embodiment, the walking assembly can drive the main body to move in a predetermined direction in the water of the swimming pool, wherein the water includes underwater and water surface. "Underwater" means that the pool cleaning robot is completely submerged below the water line. "Water surface" means that the pool cleaning robot is at least partially exposed above the water line. The water suction assembly is used to provide suction force to generate negative pressure at the position of the water inlet on the housing. After the water suction assembly is started, the water flow containing impurities passes through the water inlet, the dust port and the filter cavity under the action of the suction force. The garbage in the water is retained in the filter cavity, and the water flow filtered by the filter cavity is discharged to the outside of the housing.

When the water suction assembly is started, the filtering space of the filtering assembly can effectively reduce the probability that the filtering assembly is blocked. After the arrangement, in the pool wall cleaning mode, the main body moves to the pool wall, the water discharge capacity of the water suction assembly is reduced or the water suction assembly is closed, the suction force at the position of the water inlet is reduced, and then the front roller brush is actively controlled to lift up relative to the pool bottom, the contact area of the front roller brush with the surface to be cleaned is increased in the process of switching the front roller brush from the first state to the second state, and the cleaning effect of the pool cleaning robot on the position of the pool bottom edge when switching between the pool wall and the pool bottom is improved.

[0025] The robot comprises a pool wall cleaning mode, in which the main body moves to the pool wall, the water suction component reduces the water suction volume or is closed, and the driving component drives the front roller brush to switch from the first state to the second state.

[0026] In the embodiment, the driving component and the front walking wheel are close to the front end of the main body, the front roller brush is in transmission connection with the first output gear through the roller brush transmission group, the position of the front roller brush, the driving motor and the front walking wheel is limited, and each component is in transmission connection with the transmission component, so that each component at the front end of the main body is arranged compactly, the space of the filter component is increased, the quality at the position of the front roller brush is increased, the water suction component sucks water flow, and negative pressure is formed at the water inlet position of the pool cleaning robot during the process that the water flow passes through the water inlet and the containing cavity and is discharged. Therefore, in the pool wall cleaning mode, the water suction volume of the water suction component is reduced or the water suction component is closed after the main body moves to the pool wall, the negative pressure at the water inlet position is reduced, the adsorption force of the pool cleaning robot on the pool bottom or the pool wall is reduced, the pool cleaning robot actively controls the front roller brush to be lifted relative to the pool bottom, the front roller brush is effectively switched from the first state to the second state, the contact area of the front roller brush and the surface to be cleaned is increased, the dead angle area between the pool bottom and the pool wall is better cleaned, and the cleaning effect of the pool cleaning robot on the pool bottom edge position during switching between the pool wall and the pool bottom is improved.

[0027] A third aspect of the embodiment of the application provides a pool cleaning robot, which can move in water for cleaning. The pool cleaning robot comprises:

[0028] a main body, the main body having a front end and a rear end, and the main body being provided with a detection component, the detection component being used to detect environmental information, the environmental information comprising wall surface information of a pool wall, the length of the pool cleaning robot in a horizontal direction being L1, and the width of the pool cleaning robot in a vertical direction being W1;

The positions of the front roller brush, the driving motor and the front traveling wheel, and the transmission connection of each component with the transmission assembly, make the components at the front end position of the main body arranged compactly as a whole, and the quality at the position of the front roller brush can be improved compared with other positions of the pool cleaning robot. After the arrangement, in the pool wall cleaning mode, after the main body moves to the pool wall, when the pool wall is a first wall surface, the robot cannot continue to move to the water line along the first wall surface, and the front traveling wheel and the front roller brush move to a side away from the first wall surface, so that the contact area of the front roller brush and the pool wall is increased. In this way, the first wall surface and the pool bottom intersection position can be cleaned, and the energy consumption of the cleaning robot can be effectively reduced.

[0092] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model.

[0094] In the working state of the pool cleaning robot, the front roller brush 15 stirs up dirt on the surface to be cleaned, and the water flow is driven to move to the position of the filter assembly 12 as the front roller brush 15 rotates. The suction assembly 11 generates suction force to suck the water flow containing impurities through the water inlet 131, the dust port 122, and the filter cavity 121 of the filter assembly 12, and then discharge the water flow to the outside of the housing 103. In this process, if the filter cavity 121 of the filter assembly 12 is blocked, the demand for filtering impurities in the water cannot be met, and the suction assembly 11 cannot generate negative pressure at the water inlet 131, so that the pool cleaning robot cannot perform cleaning on the pool wall 400, or in the pool wall 400 cleaning mode, the robot will slide down from the pool wall 400, and the cleaning effect is poor.

The suction assembly 11 is used to suck the water flow, so that the water flow containing impurities is discharged to the outside of the housing 103 after passing through the water inlet 131, the dust port 122, and the filter cavity 121 of the filter assembly 12;

[0100] The walking assembly 13 comprises a front walking wheel 1302, which is rotatably arranged at the front end 101;

[0101] The driving assembly is close to the front end 101. The driving assembly comprises a driving motor 1301 and a first output gear 1312. The driving motor 1301 comprises a motor rotating shaft 1311 connected with the first output gear 1312;

[0102] A front roller brush 15 rotatably arranged at the front end 101, the front roller brush 15 being used to clean a surface to be cleaned, the front roller brush 15 comprising a first state 100 in which the front roller brush 15 abuts against the pool wall 400 and the pool bottom 500, and a second state 200 in which the front roller brush 15 only abuts against the pool wall 400;

[0103] A transmission assembly 14, the transmission assembly 14 at least comprising a roller brush transmission group 142; the first output gear 1312 being in transmission connection with the front roller brush 15 through the roller brush transmission group 142;

[0104] The robot comprises a pool wall 400 cleaning mode, in the pool wall 400 cleaning mode, the main body 10 moves to the pool wall 400, the water suction assembly 11 reduces the water suction capacity or closes the water suction assembly 11 until the driving assembly drives the front roller brush 15 to switch from the first state 100 to the second state 200.

[0105] In the embodiment, the walking assembly 13 can drive the main body 10 to move in a preset direction in the water of the swimming pool, wherein the water includes underwater and water surface, "underwater" means that the pool cleaning robot is completely submerged below the water line 300, and "water surface" means that the pool cleaning robot is at least partially exposed above the water line 300. The water suction assembly 11 is used to provide a suction force to generate a negative pressure at the position of the water inlet 131 on the shell 103. After the water suction assembly 11 is started, the water flow containing impurities is filtered through the water inlet 131, the dust port 122 and the filter cavity 121 under the action of the suction force, the garbage in the water is retained in the filter cavity 121, and the water flow filtered through the filter cavity 121 is discharged to the outside of the shell 103. In some embodiments, a water outlet 132 is arranged on the shell 103, and the filtered water flow is discharged to the outside of the shell 103 through the water outlet 132. The water outlet 132 can be arranged at the top of the shell 103, and can also be arranged at other positions of the shell 103. In the embodiment and other embodiments, the position of the water outlet 132 relative to the shell 103 is not limited, and a person skilled in the art can adjust the position of the water outlet according to the actual use, which is within the scope of the embodiments of the application. Thus, the water suction assembly 11 provides a suction power for the water flow from the water inlet 131 to the water outlet 132.

[0106] In the embodiment, as shown in FIG. 1, Figure 1 , Figure 2 and Figure 14As shown, the driving motor 1301 and the front traveling wheel 1302 are close to the front end 101 of the main body 10, the front traveling wheel 1302 is in transmission connection with the first output gear 1312 through the rolling brush transmission group 142, the front rolling brush 15 is in transmission connection with the first output gear 1312 through the traveling wheel transmission group 141, and the positions of the front rolling brush 15, the driving motor 1301 and the front traveling wheel 1302 are limited, and the transmission assembly 14 is in transmission connection, so that the components at the position of the front end 101 of the main body 10 are arranged compactly as a whole, the space of the filtering assembly 12 is improved, and the quality at the position of the front rolling brush 15 is improved. When the water suction assembly 11 is started, the filtering space of the filtering assembly 12 can effectively reduce the probability of being blocked, so that after being arranged in this way, in the pool wall 400 cleaning mode, after the main body 10 moves to the pool wall 400, the water discharge capacity of the water suction assembly 11 is reduced or closed, the suction force at the position of the water inlet 131 is reduced, and then the rolling brush is actively controlled to be lifted relative to the pool bottom 500, the contact area of the front rolling brush 15 with the surface to be cleaned is improved in the process of assisting the front rolling brush 15 to switch from the first state 100 to the second state 200, and then the cleaning effect of the pool cleaning robot on the pool bottom 500 edge position when switching between the pool wall 400 and the pool bottom 500 is improved, and the dead angle area between the pool bottom and the pool wall is better cleaned.

[0107] Further, the filtering assembly 12 is arranged close to the rear end 102 of the main body 10, and the front rolling brush 15 and the driving assembly are arranged close to the front end 101 of the main body 10, so as to provide more space for the filtering assembly 12 in the accommodating cavity 104. The following will be further introduced in combination with the drawings of the specification, and the states of the pool cleaning robot in the pool wall 400 cleaning mode will be described in detail.

[0108] As shown in Figure 3 the state that the front rolling brush 15 is not in contact with the pool wall 400, in this embodiment, the water flow sucked by the water suction assembly 11 enters the water inlet 131 at the bottom of the shell 103 and is discharged from the water outlet 132 at the top of the shell 103, the driving assembly drives the front rolling brush 15 to rotate relative to the main body 10, the front rolling brush 15 stirs the water flow to the side of the water inlet 131, and the garbage in the water, especially on the surface of the pool bottom 500, is rolled up by the front rolling brush 15. The position of the water inlet 131 generates negative pressure due to the action of the water suction assembly 11, and the water discharge capacity at the water outlet 132 is large. In combination with Figure 2 the garbage in the water enters the filtering cavity 121 through the water inlet 131 and the dust inlet 122, and the impurities in the water are retained in the filtering cavity 121 arranged at the rear, and the filtered water flow is discharged through the water outlet. As described above, the transmission assembly 14 and the driving assembly are close to the front end 101 of the main body 10, the effective filtering area of the filtering cavity 121 is large, and the filtering cavity 121 is not easy to be blocked, so that the impurity containing space is improved.

[0109] like Figure 4 As shown, the front roller brush 15 is in contact with the pool wall 400 and the pool bottom 500, meaning the front roller brush 15 is currently in the first state 100. Figure 3 The difference shown is that at this time, the drainage volume of the water absorption component 11 is reduced, and consequently, the negative pressure at the water inlet 131 is reduced. The front travel wheel 1302 and the front roller brush 15 continue to rotate, so that the front roller brush 15 can clean the junction of the pool wall 400 and the pool bottom 500, that is, the edge area of ​​the pool bottom 500. In this state, there is friction between the front roller brush 15 and the pool wall 400. When the drive component drives the front roller brush 15 to continue moving towards the pool wall 400 through the roller brush transmission group 142, the front roller brush 15 can be easily lifted relative to the pool bottom 500 and moved along the pool wall 400 towards the waterline 300.

[0110] like Figure 5 As shown, this state is similar to Figure 4 The difference shown is that the water absorption assembly 11 is closed at this time, meaning the drainage volume of the water absorption assembly 11 is zero. When the drive assembly drives the front roller brush 15 to continue moving towards the pool wall 400 via the roller brush transmission group 142, compared to... Figure 4 As shown in the diagram of the water-absorbing component 11, the pool cleaning robot can more easily lift the front roller brush 15 relative to the pool bottom 500. Those skilled in the art can assess the working state of the water-absorbing component 11 in different pool conditions and cleaning modes on the pool wall 400. Figure 4 or Figure 5 The adjustment is shown. For example, when there are many impurities at the edge between the pool wall 400 and the pool bottom 500, causing the water absorption component 11 to be in the state shown... Figure 4 The drainage volume is reduced as shown, but the drainage volume is not zero. In another scenario, when facing a complex pool wall shape (400°), making it difficult for the pool robot to climb, the state of the pool cleaning robot's water suction component 11 is adjusted as follows: Figure 5 The absorbent assembly 11 is shown to be closed.

[0111] like Figure 6 As shown, this state is similar to Figure 4 as well as Figure 5 The difference shown is that in this state, the front roller brush 15 is only in contact with the pool wall 400, that is, the front roller brush 15 is in the second state 200, when it is in the state of Figure 4 as well as Figure 5 As shown, after the drive component continues to drive the front roller brush 15 to rotate, the roller brush can switch from the first state 100 to the second state 200. The front roller brush 15 rotates relative to the pool wall 400 and stirs up the debris on the pool wall 400, moving it towards the water inlet 131, thereby cleaning the pool wall 400.

[0112] Further, in one embodiment, the pool cleaning robot further comprises a water suction assembly 11, when the front roller brush 15 only abuts on the pool wall 400 in the pool wall 400 cleaning mode, the water suction assembly 11 is started or the water suction amount of the water suction assembly 11 is increased.

[0113] In the embodiment, when the front roller brush 15 only abuts on the pool wall 400 in the pool wall 400 cleaning mode, the water suction amount of the water suction assembly 11 is increased, the suction force of the whole robot bottom is improved, the contact area between the front roller brush 15 and the pool wall 400 is further improved, the friction force between the front roller brush 15 and the pool wall 400 is increased, and then the cleaning effect of the front roller brush 15 on the pool wall 400 is improved, the stability of the main body 10 moving on the pool wall 400 is improved, and the robot is prevented from sliding from the pool wall 400 to the pool bottom 500.

[0121] A transmission assembly 14, the transmission assembly 14 at least includes a rolling brush transmission assembly 142; the first output gear 1312 is in transmission connection with the front rolling brush 15 through the rolling brush transmission assembly 142;

[0122] The robot includes a pool wall 400 cleaning mode, in the pool wall 400 cleaning mode, the main body 10 moves to the pool wall 400, the water suction assembly 11 reduces the water discharge capacity or closes the water suction assembly 11 until the driving assembly drives the front rolling brush 15 to switch from the first state 100 to the second state 200.

[0123] Different from the above embodiment 1, in the embodiment 2, the function of the water suction assembly 11 is redefined, the water suction assembly 11 only discharges the water flow entering the containing cavity 104 at the water inlet 131 position to the outside of the shell 103, and the technology related to the filter assembly 12 is not introduced, and the related technology can refer to the above embodiment or other prior art. In this embodiment, the description of the related state and function of the pool cleaning robot in the pool wall 400 cleaning mode refers to the above embodiment, and only the beneficial effects of the present embodiment compared with the prior art are briefly described below.

[0124] In this embodiment, compared with the prior art, the driving assembly and the front walking wheel 1302 are close to the front end 101 of the main body 10, the front rolling brush 15 is in transmission connection with the first output gear 1312 through the rolling brush transmission assembly 142, and the positions of the front rolling brush 15, the driving motor 1301 and the front walking wheel 1302 are limited, and the cooperation of each component and the transmission assembly 14 is matched, so that each component at the position of the front end 101 of the main body 10 is arranged compactly, the space of the filter assembly 12 is improved, and the quality at the position of the front rolling brush 15 is improved. After the water suction assembly 11 sucks, the process of discharging the water flow after passing through the water inlet 131 and the containing cavity 104, a negative pressure is formed at the position of the water inlet 131 of the pool cleaning robot.

Therefore, the pool cleaning robot actively controls when the rolling brush is lifted relative to the pool bottom 500, effectively assists the front rolling brush 15 to switch from the first state 100 to the second state 200, improves the contact area of the front rolling brush 15 with the surface to be cleaned, and improves the cleaning effect of the pool cleaning robot on the edge position of the pool bottom 500 when switching between the pool wall 400 and the pool bottom 500.

[0125] Embodiment 3

[0126] A third aspect of the embodiments of the present application provides a pool cleaning robot, the pool cleaning robot can move in water for cleaning, the pool cleaning robot comprises:

[0127] a main body 10, the main body 10 has a front end 101 and a rear end 102, and the main body 10 is provided with a detection assembly 105 for detecting environmental information, the environmental information including wall surface information of a pool wall 400, in a horizontal direction, the length of the pool cleaning robot is L1, and in a vertical direction, the width of the pool cleaning robot is W1;

[0128] a walking assembly 13, the walking assembly 13 comprises a front walking wheel 1302 arranged close to the front end 101;

[0129] a driving assembly, the driving assembly is close to the front end 101, the driving assembly comprises a driving motor 1301 and a first output gear 1312, the driving motor 1301 comprises a motor rotating shaft 1311, and the motor rotating shaft 1311 is connected with the first output gear 1312;

[0130] a transmission assembly 14, the transmission assembly 14 comprises a rolling brush transmission group 142;

[0131] a front rolling brush 15, the front rolling brush 15 is rotatably arranged on the front end 101, the front rolling brush 15 is used for cleaning a surface to be cleaned, and the first output gear 1312 is in transmission connection with the front rolling brush 15 through the rolling brush transmission group 142;

[0132] The pool cleaning robot comprises a pool wall 400 cleaning mode, in the pool wall 400 cleaning mode, the main body 10 moves to the pool wall 400, when the pool wall 400 is a first wall surface 16, the front walking wheel 1302 and the front rolling brush 15 move away from the first wall surface 16 when the robot cannot continue to move to the water line 300 along the first wall surface 16, when the pool wall 400 is a second wall surface 17, the front walking wheel 1302 and the front rolling brush 15 continue to move to the water line 300 along the second wall surface 17 until the robot reaches the water line 300, wherein the first wall surface 16 is an inwardly concave arc surface in the forward direction of the robot, the first wall surface 16 has an entry opening 161, the vertical diameter of the entry opening 161 is a maximum value L2, the horizontal diameter of the entry opening 161 is a maximum value W2, L2>L1, W2>W1, and the second wall surface 17 is a vertical wall.

[0133] The embodiment 3 is different from the above-mentioned embodiment 2, and the embodiment 3 does not emphasize the influence of the water absorption assembly 11 on the cleaning state of the pool cleaning robot, but emphasizes that the detection assembly 105 is arranged on the main body 10, the environmental information in the pool can be detected through the detection assembly 105, the environmental information includes the information of the pool wall 400, the cleaning mode of the pool cleaning robot is detected and controlled through the detection assembly 105, the intelligent cleaning is realized, and the energy consumption is further reduced.

[0134] As an example, the detection assembly 105 includes a distance sensor, an image acquisition sensor, a line laser, an IMU or an odometer arranged on the main body 10, the moving posture of the robot is detected through the IMU, or the driving mileage of the robot is detected through the odometer, so as to judge the driving distance or the moving position of the pool robot.

[0135] It needs to be further explained that in the embodiment, the detection assembly 105 is used to collect the environmental information in the pool, and the motion mode and the cleaning mode of the main body 10 are adjusted through the environmental information collected by the detection assembly 105 of the pool cleaning robot, in the embodiment, after the detection assembly 105 detects the environmental information, the driving motor 1301 and the front walking wheel 1302 are close to the front end 101 of the main body 10, the front walking wheel 1302 is in transmission connection with the first output gear 1312 through the walking wheel transmission assembly 141, and the front roller brush 15 is in transmission connection with the first output gear 1312 through the roller brush transmission assembly 142.

[0136] Through the position limitation of the front roller brush 15, the driving motor 1301 and the front walking wheel 1302, and the cooperation of the transmission connection of each component and the transmission assembly 14, each component at the position of the front end 101 of the main body 10 is arranged compactly, and the quality at the position of the front roller brush 15 can be improved compared with other positions of the pool cleaning robot.

[0137] Further, in the pool wall 400 cleaning mode, after the main body 10 moves to the pool wall 400, the pool wall 400 is the first wall surface 16, the robot cannot continue to move to the water line 300 position along the first wall surface 16, the front walking wheel 1302 and the front roller brush 15 move away from the side of the first wall surface 16, the contact area of the front roller brush 15 and the pool wall 400 is improved, so that the intersection position of the first wall surface 16 and the pool bottom 500 can be cleaned, and the energy consumption of the cleaning robot can be effectively reduced.

[0138] Furthermore, in the pool wall 400 cleaning mode, after the main body 10 moves to 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, the drainage volume of the water absorption component 11 is reduced or closed, which can reduce the suction force at the water inlet 131 position, thereby actively controlling when the roller brush is lifted relative to the pool bottom 500. During the process of the front roller brush 15 switching from the first state 100 to the second state 200, the contact area between the front roller brush 15 and the surface to be cleaned is increased, thereby improving the cleaning effect of the pool cleaning robot on the edge of the pool bottom 500 when switching between the pool wall 400 and the pool bottom 500.

[0139] The following is a detailed description of the different cleaning states of the first wall surface 16 and the second wall surface 17 when the pool cleaning robot performs the pool wall 400 cleaning mode in Example 3.

[0140] like Figure 7 As shown, this is a schematic diagram of the state of the front roller brush 15 of the pool cleaning equipment when it is in contact with both the first wall surface 16 and the pool bottom 500. The walking component 13 continues to drive the main body 10 towards the first wall surface 16. The front roller brush 15 contacts the first wall surface 16. The detection component 105 detects information about the pool wall 400 in real time, such as the tilt angle of the pool wall 400 relative to the pool bottom 500, or the distance the main body 10 moves within the pool wall 400. The front roller brush 15 rotates at the junction of the pool bottom 500 and the first wall surface 16. Driven by the friction of the front roller brush 15, the junction of the first wall surface 16 and the pool bottom 500 can be cleaned effectively. When the front roller brush 15 rotates to the position shown... Figure 8 As shown, when the front roller brush 15 is only in contact with the first wall surface 16, the main body 10 gradually moves from the entry opening 161 formed by the first wall surface 16 to the inwardly concave arc-shaped area of ​​the first wall surface 16. Since L2 > L1 and W2 > W1, as Figure 9 In the illustrated state, after moving a distance along the first wall 16 towards the waterline 300, the pool cleaning robot can no longer move towards the waterline 300. The robot then moves away from the first wall 16. For example, the front roller brush 15 moves vertically downwards along the first wall 16, gradually moving until it is completely out of contact with the first wall 16. Thus, even when the pool cleaning robot needs to clean the first wall 16 in the pool wall 400 cleaning mode, it can ensure that at least a portion of the first wall 16 and the junction between the first wall 16 and the pool bottom 500 are effectively cleaned.

[0141] Furthermore, in the swimming pool cleaning equipment provided in this application embodiment, the first wall surface 16 has a top in the vertical direction, the top is located inside the inlet opening 161, and the distance between the top and the horizontal plane where the pool bottom 500 is located is L3, where L3 > L2.

[0142] In the embodiment, when L3>L2, the pool cleaning robot has an arc-shaped surface between the top of the first wall surface 16 and the top of the entry opening 161, which cannot be cleaned. The front walking wheel 1302 and the front roller brush 15 move away from the first wall surface 16.

[0143] The pool cleaning device provided by the embodiment has a gradually increasing curvature of the first wall surface 16 in the vertical upward direction.

[0144] In the embodiment, the front roller brush 15 gradually moves away from the first wall surface 16 due to the gradually increasing curvature of the first wall surface 16, which reduces the friction between the front roller brush 15 and the first wall surface 16. After the detection assembly 105 identifies the state of the first pool wall 400, the front walking wheel 1302 and the front roller brush 15 can be controlled to move away from the first wall surface 16.

[0145] As shown in FIG. 4, the pool wall 400 is a second wall surface 17, which is a vertical wall. The front roller brush 15 contacts the second wall surface 17. The driving assembly drives the front roller brush 15 to gradually move along the second wall surface 17 from the pool bottom 500 to the water line 300, thereby cleaning the second wall surface 17. Figure 10 Figures 7-9 As shown in FIG. 4, the pool wall 400 is a second wall surface 17, which is a vertical wall. The front roller brush 15 contacts the second wall surface 17. The driving assembly drives the front roller brush 15 to gradually move along the second wall surface 17 from the pool bottom 500 to the water line 300, thereby cleaning the second wall surface 17.

[0146] Embodiment 4

[0147] The fourth aspect of the embodiment provides a pool cleaning robot, which can move in water to clean. The pool cleaning robot comprises:

[0148] The main body 10 has a front end 101 and a rear end 102 in the advancing direction of the robot.

[0149] The walking assembly 13 comprises a front walking wheel 1302 close to the front end 101.

[0150] The driving assembly is close to the front end 101. The driving assembly comprises a driving motor 1301 and a first output gear 1312. The driving motor 1301 comprises a motor rotating shaft 1311 connected to the first output gear 1312.

[0151] In the vertical direction, the rotating shaft of the front walking wheel 1302 is located in a first plane 18, the bottom of the front walking wheel 1302 is located in a second plane 19, and the rotating shaft of the first output gear 1312 is located between the first plane 18 and the second plane 19.

[0152] The transmission assembly 14 comprises a walking wheel transmission group 141.

[0153] ​A front roller brush 15 is rotatably arranged at the front end 101 and used for cleaning a surface to be cleaned. The first output gear 1312 is in transmission connection with the front roller brush 15 through a roller brush transmission group 142. The line between the rotation center of the first output gear 1312, the rotation center of the front traveling wheel 1302 and the rotation center of the front roller brush 15 forms three angles. The angle with the rotation center of the front traveling wheel 1302 as the vertex is a first angle β, and β < 150°.

[0154] The embodiment 4 is different from the embodiment 1 in that the influence of the water suction assembly 11 and the filter assembly 12 on the pool cleaning robot is not emphasized in the embodiment 4. The related technology can refer to the embodiment 1 or other prior art. In the embodiment, the description of the filter assembly 12 and the water suction assembly 11 is not too much. In the embodiment, the description of the related state and function of the pool cleaning robot in the pool wall 400 cleaning mode refers to the above embodiment. The beneficial effects of the embodiment compared with the prior art are briefly described below.

[0155] As shown in Figure 11 and Figure 12 It needs to be further explained that in the embodiment, the driving motor 1301 and the front traveling wheel 1302 are close to the front end 101 of the main body 10. The front traveling wheel 1302 is in transmission connection with the first output gear 1312 through a traveling wheel transmission group 141. The front roller brush 15 is in transmission connection with the first output gear 1312 through a roller brush transmission group 142. The first angle β < 150°. The front roller brush 15, the driving motor 1301, the front traveling wheel 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. The overall compact arrangement of each component at the position of the front roller brush 15 and the position of the front end 101 of the main body 10 is improved. After the arrangement, when the robot is in the pool bottom 500 cleaning mode or the pool wall 400 cleaning mode, the front roller brush 15 can be effectively prevented from being lifted relative to the pool bottom 500 in the accidental situation. It is helpful to improve the contact area of the front roller brush 15 with the surface to be cleaned and improve the cleaning effect of the pool cleaning robot on the edge position of the pool bottom 500 when switching between the pool wall 400 and the pool bottom 500.

[0156] Some structural components are further described below. These structural components can be selectively applied to the embodiment 1, the embodiment 2, the embodiment 3 and the embodiment 4. Through the arrangement of these structural components, the cleaning effect of the pool cleaning robot in the embodiment 1, the embodiment 2, the embodiment 3 and the embodiment 4 is improved.
