Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a cleaning robot. Background Technology

[0002] With the increasing popularity of modern swimming pools, cleaning robots, such as pool robots, have become essential tools for maintaining water quality. To effectively guide the direction of water flow, a grating is typically installed at the outlet. The grating prevents larger debris from directly clogging the outlet, ensuring smooth water flow. However, the gratings on existing pool robots are usually fixed and cannot be adjusted or cleaned as needed. When the outlet is blocked by debris, the fixed and non-adjustable grating requires manual intervention with tools to disassemble or clean the outlet and grating, increasing the complexity and inconvenience of use. Utility Model Content

[0003] This application proposes a cleaning robot. By quickly and easily connecting a grille to the water outlet of the robot body, the grille can be disassembled for cleaning when the water outlet is blocked, thereby effectively preventing the water outlet from being blocked by debris and ensuring the normal operation of the cleaning robot.

[0004] In a first aspect, embodiments of this application propose a cleaning robot, including a body, a track wheel assembly, a water pump assembly, a filter device, and a grid; two sets of track wheel assemblies are disposed on the left and right sides of the body for driving the cleaning robot forward; the water pump assembly and the filter device are both disposed inside the body, the water pump assembly is used to draw liquid and garbage into the filter device, and discharge the filtered liquid from the outlet of the body; the grid is disposed at the outlet, and the grid includes a mounting frame detachably connected to the body and multiple baffles disposed on the mounting frame, the multiple baffles being spaced apart at the outlet.

[0005] This embodiment of the application reduces the probability of large particulate pollutants in the external environment directly clogging the water outlet by covering the water outlet with multiple baffles, thereby ensuring that the water can be discharged smoothly from the water outlet and the cleaning robot can operate normally. In addition, by detachably connecting the mounting bracket to the body, the first grille can be quickly and conveniently removed from the body for cleaning when the water outlet is blocked, thereby effectively reducing the negative impact of the water outlet being blocked by debris on the normal operation of the cleaning robot.

[0006] In one possible implementation, multiple baffles are positioned along a first direction, which is the forward direction of the cleaning robot. These baffles are staggered along a second direction and spaced apart along a third direction, which is the drainage direction of the outlet. The third direction is perpendicular to the plane formed by the first and second directions. This increases the dimension along the second direction for the local outlet formed between any two adjacent baffles without increasing the spacing between them. This increases the water outlet area when the grid covers the outlet, improving the liquid throughput per unit time. This allows more liquid to be cleaned to be drawn into the filtration device by the pump assembly within a given time. Simultaneously, since the spacing between the baffles is not increased, the probability of large particulate contaminants directly clogging the outlet through the grid is not increased, ensuring the normal operation of the cleaning robot and improving its cleaning efficiency.

[0007] In one possible implementation, multiple baffles are inclined relative to the plane formed by the first and second directions. This allows the water discharged from the outlet to be sprayed at an angle. The recoil force generated by the angled water spray can have components along the second and third directions. The component along the second direction provides ground pressure for the cleaning robot, ensuring its stable operation. The component along the third direction helps the cleaning robot move in that direction, i.e., lateral movement, thus enriching the application scenarios of the cleaning robot.

[0008] In one possible implementation, the grid is a first grid, and the cleaning robot also includes a second grid. Along the drainage direction of the outlet, the water pump assembly, the second grid, and the first grid are arranged in sequence. The first baffle of the first grid and the second baffle of the second grid form a flow guide surface. The mounting part of the second grid and the flow guide cover of the water pump assembly form a flow guide channel. The flow guide surface and the flow guide channel facilitate the discharge of cleaning liquid from the outlet under the action of the water pump assembly, thereby improving the cleaning efficiency of the cleaning robot.

[0009] One possible implementation includes a mounting component positioned between the first and second grilles and detachably connected to the robot body. The mounting component has mounting holes, with the mounting portion interlocking with these holes. After the first and second grilles are removed for cleaning, this allows the second grille to be quickly and easily reinstalled into the robot body, shortening its installation time and thus improving the cleaning efficiency of the robot. Furthermore, the mounting component is structured as multiple first baffles that mimic the shape of the first grille. Therefore, liquid passing through the first grille can be blocked by the mounting component except for the mounting holes. The liquid can only flow through the guide channel formed by the mounting portion and the guide shroud. This prevents liquid carrying particulate contaminants from the external environment from flowing from the outlet into other parts of the robot body, thus reducing the cleaning difficulty of the robot.

[0010] In one possible implementation, there are two water outlets, two water pump assemblies, and two second grilles, symmetrically arranged about the centerlines of the two sets of track wheel assemblies. That is, the second baffles of the two second grilles are tilted in opposite directions relative to the plane formed by the first and second directions, allowing the two opposing forces from the water sprayed from the two outlets to have two opposite lateral components. When both water pump motors operate simultaneously, these two opposite lateral components cancel each other out, allowing the cleaning robot to move forward along the first direction driven by the track wheel assemblies. When only one water pump motor operates, the lateral component along the third direction can drive the cleaning robot to move laterally, enriching the application scenarios of the cleaning robot.

[0011] In one possible implementation, the mounting bracket is equipped with snap-fit ​​connectors, and the body is equipped with snap-fit ​​holes. The grille and the body are detachably connected via the snap-fit ​​connectors and snap-fit ​​holes. When the outlet becomes clogged, the first and second grilles can be quickly and easily removed from the body for cleaning, thereby effectively reducing the negative impact of debris clogging the outlet on the normal operation of the cleaning robot.

[0012] In one possible implementation, the mounting frame is equipped with a magnet, and the body is equipped with a magnetic component. The grille and the body are detachably connected via the magnet and the magnetic component. When the outlet becomes clogged, the first and second grilles can be quickly and easily removed from the body for cleaning, thereby effectively reducing the negative impact of debris clogging the outlet on the normal operation of the cleaning robot.

[0013] In one possible implementation, the mounting frame is equipped with multiple positioning posts, and the body has multiple positioning holes. The grille and the body are positioned by the positioning posts and positioning holes. After the first and second grilles are removed for cleaning, the first grille can be quickly and easily reinstalled into the body, shortening the installation time of the first grille and thus improving the cleaning efficiency of the cleaning robot.

[0014] In one possible implementation, the grille is symmetrically arranged about the centerline of the two sets of track wheel assemblies. This makes the reaction force from the cleaning liquid discharged from the outlet of the machine more uniform, which is beneficial for the cleaning robot to smoothly conform to the surface to be worked under the drive of the track wheel assemblies.

The directional terms used in the embodiments of this application, such as "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "side," "top," and "bottom," are merely for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0024] With the widespread use of modern swimming pools, pool cleaning robots have become essential tools for maintaining water quality. Existing pool robots typically include a water pump assembly housed within the robot's body, which discharges water through an outlet. The impeller of the pump assembly is located at the outlet to propel the water flow. To effectively guide the water flow, a grating is usually installed at the outlet. The grating is designed to prevent larger debris from directly clogging the outlet, ensuring smooth water discharge. However, the gratings on existing pool robots are usually fixed and cannot be adjusted or cleaned as needed. In actual use, when the outlet is blocked by debris (such as leaves, fragments, etc.) in the pool, water flow may be obstructed, severely impacting the cleaning efficiency of the robot. Because the grating is fixed and cannot be adjusted, manual intervention with tools is required to disassemble or clean the outlet and grating, increasing the complexity and inconvenience of use and reducing the user experience.

[0025] Figure 1 This is a schematic diagram of the structure of the cleaning robot 1 provided in the embodiments of this application. Figure 3 yes Figure 1 The schematic diagram of the BB cross-sectional structure of the cleaning robot 1 shown is combined with... Figure 1 and Figure 3 As shown, the cleaning robot 1 proposed in this embodiment includes a body 11, track wheel assemblies 12, cleaning brushes 13, a filter device 14, a water pump assembly 4, and a first grid 2. Two sets of track wheel assemblies 12 are disposed on the left and right sides of the body 11 to drive the cleaning robot 1 forward. The cleaning brushes 13 can be disposed on the body 11 along the forward direction of the cleaning robot 1, that is, the cleaning brushes 13 can be disposed at the front and rear of the body 11. In one possible implementation, the number of cleaning brushes 13 can be at least two, and at least two cleaning brushes 13 can be disposed along the forward direction of the cleaning robot 1. Both the water pump assembly 4 and the filter device 14 are disposed inside the body 11. The cleaning brushes 13 can be used to clean surfaces to be cleaned, such as the bottom and walls of a swimming pool.

[0026] Combination Figure 1 and Figure 3 As shown, the water pump assembly 4 is used to draw liquid and waste into the receiving chamber of the filter device 14 through the suction port of the body 11. The filter screen of the filter device 14 filters the liquid to be cleaned and removes particulate contaminants from the liquid. The resulting clean liquid flows along... Figure 3 The path indicated by the black arrow is used to discharge the cleaning liquid. Under the suction of the water pump assembly 4, the cleaning liquid passes through the filter screen of the filter device 14 and the water outlet channel inside the body 11 in sequence, and is finally discharged from the water outlet 111 of the body 11. This provides ground pressure to the cleaning robot 1, allowing the cleaning robot 1 to run smoothly under the drive of the track wheel assembly 12.

[0027] Figure 2 yes Figure 1 The diagram shown is a cross-sectional view of the cleaning robot 1. Figure 4 This is an exploded view of the cleaning robot 1 provided in the embodiments of this application, combined with... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first grille 2 may include a mounting frame 21 detachably connected to the body 11 and a plurality of first baffles 22 disposed on the mounting frame 21. The length direction of the plurality of first baffles 22 is along a first direction, which is the forward direction of the cleaning robot 1. The plurality of first baffles 22 are spaced apart on the mounting frame 21, and the first grille 2 is located at the water outlet 111, that is, the plurality of first baffles 22 are spaced apart at the water outlet 111, so that the plurality of first baffles 22 partially cover the water outlet 111, thereby reducing the probability of larger particulate pollutants in the external environment directly clogging the water outlet 111, thereby ensuring that water can be smoothly discharged from the water outlet 111 and the cleaning robot 1 can operate normally. In this embodiment of the application, by detachably connecting the mounting frame 21 to the body 11, when the water outlet 111 is blocked, the first grille 2 can be quickly and conveniently removed from the body 11 for cleaning, thereby effectively reducing the negative impact of the water outlet being blocked by debris on the normal operation of the cleaning robot 1.

[0028] Figure 6 This is a schematic diagram of the structure of the first grille 2 provided in the embodiments of this application, combined with... Figure 1 , Figure 2 and Figure 6 As shown, in one possible implementation, a plurality of first baffles 22 may be staggered in a second direction and spaced apart along a third direction, where the second direction is the drainage direction of the outlet 111, and the third direction may be perpendicular to the plane formed by the first and second directions. The staggered arrangement of the plurality of first baffles 22 in the second direction means that any two first baffles 22 have a height difference in the second direction. Schematic, a first baffle 22 may include a first end 221 and a second end 222. For example... Figure 2As shown, the first end 221 of the first baffle 22 near the center line L0 of the two sets of track wheel assemblies 12 is higher than the first end 221 of the first baffle 22 away from the center line L0, and the second end 222 of the first baffle 22 near the center line L0 is higher than the second end 222 of the first baffle 22 away from the center line L0. This increases the size along the second direction of the local water outlet formed between any two adjacent first baffles 22 without increasing the interval between any two adjacent first baffles 22. That is, it increases the water outlet area of ​​the machine body 11 when the first grid 2 part covers the water outlet 111, and increases the liquid throughput of the machine body 11 per unit time, so that more liquid to be cleaned can be drawn into the filter device 14 by the water pump assembly 4 within a unit time. Meanwhile, since the spacing between the multiple first baffles 22 is not increased, the probability of larger particulate pollutants directly clogging the outlet 111 through the first grille 2 will not increase. In other words, the solution of this embodiment increases the liquid throughput of the body 11 per unit time while reducing the probability of larger particulate pollutants directly clogging the outlet 111, ensuring the normal operation of the cleaning robot 1 and improving its cleaning efficiency. It should be noted that the above-mentioned arrangement of the multiple first baffles 22 is only one implementation method; other arrangements of the multiple first baffles 22 can also achieve the same effect. For example, the multiple first baffles 22 can be staggered in the second direction and spaced apart along the first direction, still increasing the size along the second direction for any two adjacent first baffles 22 forming a local outlet, thereby increasing the liquid throughput of the body 11 per unit time.

[0029] Combination Figure 1 , Figure 2 and Figure 6 As shown, in one possible implementation, multiple first baffles 22 are all inclined relative to the plane formed by the first direction and the second direction. Schematic, the multiple first baffles 22 can form an angle with the second direction and the third direction, allowing the water discharged from the outlet 111 to be sprayed at an angle. The recoil force generated by the angled water spray can have components along the second direction and the third direction. The component along the second direction can provide ground pressure for the cleaning robot 1, ensuring its stable operation. The component along the third direction can facilitate the cleaning robot 1's movement along that direction, i.e., lateral movement, enriching the application scenarios of the cleaning robot 1.

[0030] Combination Figure 1 , Figure 2 and Figure 6As shown, in one possible implementation, the first grid 2 can be symmetrically arranged about the center line L0 of the two sets of track wheel assemblies 12. This makes the reverse force generated by the cleaning liquid being discharged from the outlet 111 of the body 11 more uniform, which is beneficial for the cleaning robot 1 to smoothly conform to the surface to be worked under the drive of the track wheel assembly 12.

[0031] Combination Figure 2 and Figure 4 As shown, in one possible implementation, the cleaning robot 1 further includes a second grille 3. Along the drainage direction of the outlet 111, i.e., along the third direction, the pump assembly 4, the second grille 3, and the first grille 2 are arranged sequentially. The second grille 3 includes a mounting portion 31 and a plurality of second baffles 32, which partially cover the outlet 111. In one possible implementation, the length direction of the plurality of second baffles 32 is along the first direction. The plurality of second baffles 32 can be staggered in the second direction and spaced apart along the third direction. This can also increase the water outlet area of ​​the robot body 11 when the first grille 2 and the second grille 3 partially cover the outlet 111, allowing more liquid to be cleaned to be drawn into the filter device 14 by the pump assembly 4 within a unit. In addition, the positions of the multiple first baffles 22 can correspond to the positions of the multiple second baffles 32, and the first baffles 22 can abut against the second baffles 32, so that the first baffles 22 and the second baffles 32 can form a continuous surface, namely the guide surface 321, which is conducive to the discharge of cleaning liquid from the outlet 111 under the action of the water pump assembly 4, thereby improving the cleaning efficiency of the cleaning robot 1.

[0032] Combination Figure 2 and Figure 4 As shown, the water pump assembly 4 may include an impeller 41, a guide shroud 42, and a water pump motor 43. The water pump motor 43 drives the impeller 41 to rotate to generate a suction effect. The guide shroud 42 may be arranged around the impeller 41 to guide the cleaning liquid out of the outlet 111. The mounting part 31 may be cylindrical. Along the third direction, the mounting part 31 may abut against the guide shroud 42 to form a guide channel 311. The guide channel 311 helps to increase the discharge efficiency of the cleaning liquid from the outlet 111.

[0033] Figure 5 This is another exploded view of the cleaning robot 1 provided in the embodiments of this application, combined with Figure 2 , Figure 4 and Figure 5As shown, in one possible implementation, the cleaning robot 1 further includes a mounting component 5, which can be disposed between the first grille 2 and the second grille 3. The mounting component 5 may have a mounting hole 51, into which the second grille 3 can be fitted, such that the mounting portion 31 of the second grille 3 is interference-fitted with the mounting hole 51. The mounting component 5 is detachably connected to the body 11. After the first grille 2 and the second grille 3 are removed for cleaning, it can help the second grille 3 to be quickly and easily reinstalled into the body 11, shortening the installation time of the second grille 3 and thus improving the cleaning efficiency of the cleaning robot 1. In addition, the mounting component 5 is a structure composed of multiple first baffles 22 that conform to the first grille 2. Therefore, the liquid passing through the first grille 2 can be blocked by the other parts of the mounting component 5 except for the mounting hole 51. The liquid can only flow in the guide channel 311 formed by the mounting portion 31 and the guide shroud 42. This can prevent liquid carrying particulate pollutants from the external environment from flowing from the outlet 111 to other parts inside the body 11 and causing pollution, thus reducing the cleaning difficulty of the cleaning robot 1.

[0034] Combination Figure 2 , Figure 4 and Figure 5 As shown, in one possible implementation, there are two outlets 111, two pump assemblies 4, and two second grilles 3, all symmetrically arranged about the centerline L0. The second baffles 32 of the two second grilles 3 are tilted in opposite directions relative to the plane formed by the first and second directions, so that the two opposing forces from the water sprayed from the two outlets 111 can have two lateral components in opposite directions. When the two pump motors 43 operate simultaneously, the two lateral components in opposite directions can cancel each other out, and the cleaning robot 1 can move forward along the first direction driven by the track wheel assembly 12. When only one pump motor 43 operates, the lateral component along the third direction can drive the cleaning robot 1 to move laterally. Schematically, at this time, the cleaning robot 1 can move laterally along the waterline of the pool wall to clean the dirt on the pool wall using the cleaning brush 13.

[0035] Combination Figure 1 , Figure 4 and Figure 6As shown, in one possible implementation, the mounting bracket 21 of the first grille 2 may be provided with a snap-fit ​​component 211, and the body 11 may be provided with a snap-fit ​​hole 112. The first grille 2 and the body 11 can be detachably connected via the snap-fit ​​component 211 and the snap-fit ​​hole 112. When the snap-fit ​​component 211 and the snap-fit ​​hole 112 form a snap-fit ​​engagement, the first grille 2 can be connected to the body 11; when the snap-fit ​​component 211 and the snap-fit ​​hole 112 are disengaged, the first grille 2 can be removed from the body 11. When the outlet 111 is blocked, the first grille 2 and the second grille 3 can be quickly and conveniently removed from the body 11 for cleaning, thereby effectively reducing the negative impact of debris blockage on the normal operation of the cleaning robot 1.

[0036] In another possible embodiment of this application, the mounting bracket 21 of the first grille 2 may be equipped with a magnet, and the body 11 may be equipped with a magnetic component. The first grille 2 and the body 11 can be detachably connected via the magnet and the magnetic component. When a certain magnetic attraction effect is generated between the magnet and the magnetic component, the first grille 2 can be connected to the body 11; when the magnetic force between the magnet and the magnetic component is overcome, the first grille 2 can be removed from the body 11. When the water outlet 111 is blocked, the first grille 2 and the second grille 3 can be quickly and conveniently removed from the body 11 for cleaning, thereby effectively reducing the negative impact of the water outlet being blocked by debris on the normal operation of the cleaning robot 1.

[0037] Combination Figure 1 , Figure 4 and Figure 6 As shown, in one possible implementation, the mounting frame 21 may be provided with multiple positioning posts 212, and the body 11 may be provided with multiple positioning holes 113. The first grille 2 and the body 11 can be positioned by the positioning posts 212 and the positioning holes 113. After the first grille 2 and the second grille 3 are removed for cleaning, the positioning engagement of the positioning posts 212 and the positioning holes 113 can help the first grille 2 to be quickly and easily reinstalled into the body 11, shortening the installation time of the first grille 2 and thus improving the cleaning efficiency of the cleaning robot 1.

[0038] In summary, this application, by quickly connecting the grille to the water outlet of the machine body, allows for rapid and convenient removal of the grille for cleaning when the water outlet becomes blocked, thereby effectively reducing the negative impact of debris blockage on the normal operation of the cleaning robot.
