Description

Technical Field

[0001] This application relates to the field of pool cleaning equipment technology, and in particular to a pool robot. Background Technology

[0002] With the increasing popularity of swimming pool applications, the demand for automated pool cleaning is growing, and pool robots (pool cleaning machines) have become the mainstream cleaning equipment.

[0003] Currently, most pool cleaning robots on the market use motor-driven rotating wheels or tracks for their locomotion. The robots move by leveraging the friction between the wheels / tracks and the pool bottom or sidewalls to complete the cleaning task. However, this approach has the following problems:

[0004] It requires multiple mechanical components such as drive motors, transmission shafts, and geared motors, which not only increases manufacturing costs but also makes assembly difficult. Among these, motors are the most expensive core components, and usually three or more are required, further increasing product costs. Maintenance costs are also high, as the filter structure is prone to rapid clogging in swimming pools with many impurities, requiring frequent shutdowns for maintenance. Summary of the Invention

[0005] In order to reduce product costs and reduce downtime for maintenance, this application provides a swimming pool robot.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A swimming pool robot includes a robot body with two symmetrically arranged water outlets at its tail and a water inlet at its bottom that communicates with the water outlets. A filtration mechanism, a power mechanism, and a flow diversion mechanism are provided between the water inlet and the water outlets. A control mechanism is provided inside the robot body. The power mechanism and the flow diversion mechanism are electrically connected to the control mechanism to generate the required water flow from the water inlet to the water outlet and to create the required water flow difference between the two sets of water outlets to achieve the robot body's turning.

[0008] Furthermore, the filtration mechanism includes a backflow preventer, a filter assembly, and a cleaning assembly. The backflow preventer is located at the water inlet, and the filter assembly is located on top of the backflow preventer, so that water flows through the backflow preventer and the filter assembly in sequence. The cleaning assembly is located on the filter assembly and is connected to a power mechanism for transmission, so that the cleaning assembly cleans and unblocks the filter assembly.

[0009] Furthermore, the anti-reverse component includes a mounting frame and an anti-reverse plate. The mounting frame is disposed at the water inlet and forms a water inlet channel, and the anti-reverse plate is disposed at the mounting frame and forms a one-way seal for the water inlet channel. The filtration component includes a filter frame and a filter screen. The filter frame is disposed at the mounting frame and forms a filter chamber, and the filter screen is disposed at the filter frame and is used to intercept impurities in the filter chamber. The cleaning component includes a rotating shaft and a cleaning brush. The rotating shaft is disposed at the filter frame and is connected to the power mechanism for transmission. The cleaning brush is disposed at the rotating shaft and is in sliding contact with the filter screen.

[0010] Furthermore, the water inlet extends vertically inward to form a plug-in portion, the bottom of the mounting frame is provided with a plug-in groove adapted to the plug-in portion, the top of the mounting frame is provided with a first stepped groove, the bottom of the filter frame is provided with a second stepped groove adapted to the first stepped groove, one side of the top of the mounting frame is provided with a C-shaped hinge ear, one side of the bottom of the filter frame is provided with a hinge shaft adapted to the C-shaped hinge ear, the other side of the top of the mounting frame is provided with a snap-fit ​​plate, the other side of the bottom of the filter frame is provided with a snap-fit ​​block adapted to the snap-fit ​​plate; a maintenance cover is provided on the top of the robot body corresponding to the filter component position area, one side of the maintenance cover is hinged to the robot body, the other side of the maintenance cover is snap-fitted to the robot body, and the maintenance cover is pressed against the top of the filter frame.

[0011] Furthermore, the power mechanism includes a mounting box, a dual-axis motor, an impeller, and a reducer. The mounting box is located inside the robot body, and the dual-axis motor is located inside the mounting box. The first output end of the dual-axis motor passes through the mounting box and extends to the intersection of the two sets of water outlets. The impeller is located at the first output end of the dual-axis motor. The reducer is located inside the mounting box, and the input end of the reducer is connected to the second output end of the dual-axis motor. The output end of the reducer passes through the mounting box and extends to the filter frame. A first magnet is provided at the output end of the reducer, and a second magnet is provided at one end of the rotating shaft near the reducer. The first magnet and the second magnet are magnetically attracted to each other.

[0012] Furthermore, the filter frame is provided with a first circular sliding hole that is movably adapted to the rotating shaft, so that the rotating shaft has the freedom to rotate and slide relative to the filter frame. The cleaning brush is provided with a second circular sliding hole that is movably adapted to the rotating shaft. A limiting groove extending along its axial direction is provided on the inner circumference of the second circular sliding hole. A limiting strip extending along its axial direction is provided on the outer circumference of the rotating shaft. The limiting strip is slidably disposed in the limiting groove, so that the cleaning brush has the freedom to slide relative to the rotating shaft. A third magnet is provided at the end of the rotating shaft away from the reducer, and a fourth magnet is provided on the cleaning brush. The third magnet and the fourth magnet repel each other, so that the cleaning brush always tends to stick tightly to the filter screen. The magnetic attraction between the first magnet and the second magnet is greater than the repulsive force between the third magnet and the fourth magnet.

[0013] Furthermore, an auxiliary transmission assembly is provided between the first magnet and the second magnet. The auxiliary transmission assembly includes multiple sets of transmission blocks evenly distributed along the axis of the output end of the reducer. The transmission blocks are located on the side of the first magnet facing the second magnet, and the transmission blocks are hemispherical. The side of the second magnet facing the first magnet is provided with a transmission groove that matches the transmission blocks.

[0014] Furthermore, the diversion mechanism includes two sets of flow regulating valves and two sets of flow meters. The two sets of flow regulating valves are respectively installed at the two sets of water outlets, and the two sets of flow meters are respectively installed at the two sets of water outlets. Both sets of flow regulating valves and the two sets of flow meters are electrically connected to the control mechanism.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] The control mechanism controls the power mechanism to start, so that the water flow from the internal space of the robot body to the external space is formed at the confluence of the two sets of water outlets. That is, the required water flow is formed in the direction from the inlet to the outlet. The control mechanism controls the diversion mechanism to adjust the water flow of the two sets of water outlets so that the required water flow difference is formed between the two sets of water outlets, and finally realizes the robot body to move in a straight line or turn.

[0017] When the filter frame and mounting frame are inserted into the water inlet, the first magnet and the second magnet are aligned with each other. Since the magnetic attraction between the first magnet and the second magnet is greater than the repulsive force between the third magnet and the fourth magnet, the magnetic attraction overcomes the repulsive force, and the first magnet and the second magnet attract each other. At this time, the cleaning brush is more closely attached to the filter screen. Finally, the friction between the first magnet and the second magnet is used to realize the transmission connection between the rotating shaft and the power mechanism. The rotating shaft drives the cleaning brush to rotate through the cooperation of the limiting strip and the limiting groove to achieve cleaning. This achieves both transmission effect and the detachable effect in narrow spaces. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1 to 10This application will be described in further detail.

[0030] This application discloses a swimming pool robot.

[0031] Reference Figure 1-10 The pool robot includes a robot body 1, which is a shell structure with freely rotating wheels on both sides, allowing it to move along the bottom of the pool under external power. Two symmetrically arranged water outlets 11 are located at the rear of the robot body 1, and the front ends of the two sets of water outlets 11 converge. A single water flow dynamic structure is needed at the convergence point to generate water flow dynamics between the two sets of water outlets 11. A water inlet 12 is located at the bottom of the robot body 1, and the water inlet 12 and the water outlets 11 are connected through the internal space of the robot body 1, creating a water flow in the direction of water inlet 12 - internal space of robot body 1 - water outlet 11. The robot body 1 has various water flow paths arranged sequentially along the water flow direction inside. The robot body 1 includes a filter mechanism 2, a power mechanism 3, and a diversion mechanism 4. Additionally, a control mechanism 5 is installed inside the robot body 1. Both the power mechanism 3 and the diversion mechanism 4 are electrically connected to the control mechanism 5. The control mechanism 5 controls the power mechanism 3 to create water flow from the internal space of the robot body 1 to the external space at the confluence of the two sets of outlets 11, thus creating the required water flow from the inlet 12 to the outlet 11. The filter mechanism 2 filters the water flow to intercept and recover impurities. The control mechanism 5 controls the diversion mechanism 4 to adjust the water flow of the two sets of outlets 11, creating the required water flow difference between them, ultimately enabling the robot body 1 to move in a straight line or turn.

[0032] In this embodiment, the control mechanism 5 adopts a PLC controller from the prior art, which will not be described in detail here.

[0033] In this embodiment, the filtration mechanism 2 specifically includes a backflow preventer 21, a filter 22, and a cleaning component 23. Generally speaking, the backflow preventer 21 is located at the inlet 12 to enable unidirectional water flow from the inlet 12 to the internal space of the robot body 1 and the outlet 11. The filter 22 is located at the backflow preventer 21 to filter the water flow and intercept and recycle impurities. The cleaning component 23 is located at the filter 22 and needs to be connected to the power mechanism 3 to clean and unclog the filter 22.

[0034] Specifically, the anti-reverse component 21 includes a mounting frame 211 and an anti-reverse plate 212. The mounting frame 211 is a shell structure with openings at both the top and bottom. The water inlet 12 extends vertically inward to form a plug-in part 61. The bottom of the mounting frame 211 is provided with a plug-in groove 62 that matches the plug-in part 61, so that the mounting frame 211 can be plugged into the water inlet 12 from top to bottom to form a water inlet channel. At the same time, the two have a detachable separation effect. The anti-reverse plate 212 is a flexible plastic plate. One side of the anti-reverse plate 212 is fixedly set on the top side of the mounting frame 211. Under normal conditions, the anti-reverse plate 212 covers the top of the mounting frame 211. Under the impact of water flow, the anti-reverse plate 212 elastically detaches from the top of the mounting frame 211 to achieve a one-way seal for the water inlet channel. That is, it does not affect the forward flow of water along the direction of water inlet 12 - robot body 1 internal space - water outlet 11, and can prevent the reverse flow of water as much as possible, so as to avoid the impurities intercepted and collected by the filter component 22 from flowing back into the pool.

[0035] The filter assembly 22 specifically includes a filter frame 221 and a filter screen 222. The mounting frame 211 has a first stepped groove 63 at its top and a second stepped groove 64 at its bottom. The first stepped groove 63 and the second stepped groove 64 are embedded, so their depths can be set to 2-3 mm. A C-shaped hinge lug 65 is provided on one side of the top of the mounting frame 211, and a hinge shaft 66 adapted to the C-shaped hinge lug 65 is provided on one side of the bottom of the filter frame 221. The opening of the C-shaped hinge lug 65 is slightly larger than the outer diameter of the hinge shaft 66, and the hinge shaft 66 can be connected by the C-shaped hinge. The opening of the lug 65 is forcibly inserted, giving both the hinge and detachable separation functions. A snap-fit ​​plate 67 is provided on the other side of the top of the mounting frame 211, and a snap-fit ​​block 68, which is compatible with the snap-fit ​​plate 67, is provided on the other side of the bottom of the filter frame 221. When the filter frame 221 rotates and seals itself on the top of the mounting frame 211 through the cooperation of the C-shaped hinge lug 65 and the hinge shaft 66, the first stepped groove 63 and the second stepped groove 64 form an embedded fit, while the snap-fit ​​plate 67 and the snap-fit ​​block 68 engage in a stroke-locked fit, forming a filter chamber. The filter screen 222 is placed on the filter frame 221 and is used to intercept impurities in the filter chamber. In practical applications, the filter frame 221 and the mounting frame 211 need to be pre-assembled outside the robot body 1, and then the entire assembly is installed inside the robot body 1 from top to bottom, so that the mounting frame 211 is inserted into the water inlet 12. In this configuration, a maintenance window is provided on the top of the robot body 1 corresponding to the location of the filter assembly 22. A maintenance cover 69 is provided on the top of the robot body 1 to cover the maintenance window. One side of the maintenance cover 69 is hinged to the robot body 1, and the other side is snapped onto the robot body 1 by an elastic buckle. At this time, the maintenance cover 69 is pressed against the top of the filter frame 221 to prevent the filter frame 221 and the mounting frame 211 from moving upwards and detaching from the water inlet 12. When the filter assembly 22 accumulates a lot of impurities and needs to be cleaned regularly, the maintenance cover 69 can be opened, the filter frame 221 and the mounting frame 211 can be lifted upwards and detached from the water inlet 12, and then the filter frame 221 and the mounting frame 211 can be disassembled to achieve regular cleaning of impurities.

[0036] The cleaning component 23 specifically includes a rotating shaft 231 and a cleaning brush 232. The rotating shaft 231 is movably mounted on the filter frame 221 and is connected to the power mechanism 3. The cleaning brush 232 is movably mounted on the rotating shaft 231 and slides in contact with the filter screen 222. The power mechanism 3 drives the rotating shaft 231 and the cleaning brush 232 to rotate, so that the bristles of the cleaning brush 232 clean the sliding contact area, ensuring that the area has a good filtration effect.

[0037] In this case, the transmission connection between the rotating shaft 231 and the power mechanism 3 needs to simultaneously consider both the transmission effect and the ease of disassembly within the confined space. This is achieved in the following way:

[0038] The power mechanism 3 specifically includes a mounting box 31, a dual-axis motor 32, an impeller 33, and a reducer 34. The mounting box 31 is fixedly installed inside the robot body 1, providing a mounting base for components such as the dual-axis motor 32, reducer 34, and control mechanism 5. The dual-axis motor 32 is fixedly installed inside the mounting box 31, with its first output end movably penetrating the mounting box 31 and extending to the intersection of the two sets of water outlets 11. The impeller 33 is fixedly installed at the first output end of the dual-axis motor 32, meaning it is located at the intersection of the two sets of water outlets 11. The dual-axis motor 32 drives the impeller 33 to rotate, thus achieving rotation at the two sets of water outlets. The confluence of 11 forms a water flow from the internal space of the robot body 1 to the external space. By controlling the rotation speed of the dual-axis motor 32, the required water flow is achieved from the inlet 12 to the outlet 11. The reducer 34 is fixedly installed inside the mounting box 31. The input end of the reducer 34 is coaxially connected to the second output end of the dual-axis motor 32. The output end of the reducer 34 extends through the mounting box 31 to the filter frame 221. A first magnet 71 is fixedly installed at the output end of the reducer 34. A second magnet 72 is installed at one end of the rotating shaft 231 near the reducer 34. Both the first magnet 71 and the second magnet 72 are permanent magnets and they are magnetically attracted to each other.

[0039] The filter frame 221 is provided with a first circular sliding hole 81 that is movably adapted to the rotating shaft 231, so that the rotating shaft 231 has the freedom to rotate and slide relative to the filter frame 221. The cleaning brush 232 is provided with a second circular sliding hole 82 that is movably adapted to the rotating shaft 231. The inner circumference of the second circular sliding hole 82 is provided with a limiting groove 83 extending along its axial direction. The outer circumference of the rotating shaft 231 is provided with a limiting strip 84 extending along its axial direction. The limiting strip 84 is slidably disposed in the limiting groove 83, so that the cleaning brush 232 has the freedom to slide relative to the rotating shaft 231. A third magnet 73 is provided at the end of the rotating shaft 231 away from the reducer 34, and a fourth magnet 74 is provided on the cleaning brush 232. Both the third magnet 73 and the fourth magnet 74 are permanent magnets, and they repel each other to ensure that the cleaning brush 232 always tends to stick tightly to the filter screen 222. The magnetic attraction between the first magnet 71 and the second magnet 72 is greater than the repulsive force between the third magnet 73 and the fourth magnet 74.

[0040] First, when the filter frame 221 and the mounting frame 211 are pre-assembled outside the robot body 1, due to the repulsion between the third magnet 73 and the fourth magnet 74, the cleaning brush 232 always tends to adhere tightly to the filter screen 222, while the rotating shaft 231 always tends to slide and retract inside the filter frame 221. In other words, the length of the rotating shaft 231 exposed outside the filter frame 221 is small, facilitating the overall installation of the filter frame 221 and the mounting frame 211 inside the robot body 1 from top to bottom. Then, when the filter frame 221 and the mounting frame 211 are inserted into the water inlet 12, the first magnet 71 and the second magnet 72 are aligned. Because the magnetic attraction between the first magnet 71 and the second magnet 72 is greater than the repulsive force between the third magnet 73 and the fourth magnet 74, the magnetic attraction... Overcoming the repulsive force, the first magnet 71 and the second magnet 72 attract each other magnetically. At this time, the cleaning brush 232 is more closely attached to the filter screen 222. Finally, the friction between the first magnet 71 and the second magnet 72 is used to realize the transmission connection between the rotating shaft 231 and the power mechanism 3. The rotating shaft 231 drives the cleaning brush 232 to rotate through the cooperation of the limiting strip 84 and the limiting groove 83 to achieve cleaning. Finally, when the filter frame 221 and the mounting frame 211 are lifted and removed from the robot body 1, the first magnet 71 and the second magnet 72 are forcibly separated. The rotating shaft 231 has the tendency to retract into the filter frame 221 again due to the repulsion of the third magnet 73 and the fourth magnet 74, thus facilitating the disassembly and assembly effect in narrow spaces. That is, it simultaneously takes into account the transmission effect and the disassembly and assembly effect in narrow spaces.

[0041] In this embodiment, an auxiliary transmission assembly 9 is provided between the first magnet 71 and the second magnet 72; wherein, the auxiliary transmission assembly 9 includes multiple sets of transmission blocks 91 evenly distributed along the axis of the output end of the reducer 34, the transmission blocks 91 are fixedly disposed on the side of the first magnet 71 facing the second magnet 72, and the transmission blocks 91 are hemispherical structures, and the side of the second magnet 72 facing the first magnet 71 is provided with a transmission groove that is adapted to the transmission blocks 91. 92 In some scenarios, the bristles of the cleaning brush 232 may get stuck in the mesh of the filter screen 222, making it difficult for the cleaning brush 232 and the rotating shaft 231 to rotate. However, the output end of the reducer 34 continues to rotate, which causes the first magnet 71 and the second magnet 72 to rotate relative to each other. This causes the transmission block 91 to slide out / fall into the transmission groove continuously. That is, although the rotating shaft 231 is difficult to rotate, it can maintain normal reciprocating sliding. During the process of the transmission block 91 sliding out / falling into the transmission groove, the rotating shaft 231 generates collision vibration and transmits it to the cleaning brush 232. Through continuous vibration, the bristles of the cleaning brush 232 are disengaged from the mesh of the filter screen 222, restoring the normal cleaning effect.

[0042] In this embodiment, the diversion mechanism 4 specifically includes two sets of flow regulating valves 41 and two sets of flow meters 42. The two sets of flow regulating valves 41 are respectively set at the two sets of water outlets 11, and the two sets of flow meters 42 are respectively set at the two sets of water outlets 11. The two sets of flow regulating valves 41 and the two sets of flow meters 42 are all electrically connected to the control mechanism 5.

[0043] Implementation principle: The control mechanism 5 controls the power mechanism 3 to start, so that the water flow from the internal space of the robot body 1 to the external space is formed at the confluence of the two sets of water outlets 11. That is, the required water flow is formed from the inlet 12 to the outlet 11. The control mechanism 5 controls the diversion mechanism 4 to adjust the water flow of the two sets of water outlets 11 so that the required water flow difference is formed between the two sets of water outlets 11, and finally realizes the straight-line walking or turning of the robot body 1. When the filter frame 221 and the mounting frame 211 are inserted into the water inlet 12, the first magnet 71 and the second magnet 72 are aligned with each other. Since the magnetic attraction between the first magnet 71 and the second magnet 72 is greater than the repulsive force between the third magnet 73 and the fourth magnet 74, the magnetic attraction overcomes the repulsive force, and the first magnet 71 and the second magnet 72 are attracted to each other. At this time, the cleaning brush 232 is more closely attached to the filter screen 222. Finally, the friction between the first magnet 71 and the second magnet 72 is used to realize the transmission connection between the rotating shaft 231 and the power mechanism 3. The rotating shaft 231 drives the cleaning brush 232 to rotate through the cooperation of the limiting strip 84 and the limiting groove 83 to achieve cleaning, which simultaneously takes into account the transmission effect and the detachable effect in narrow spaces.
