In related art, swimming pool cleaning robots use different motors for movement and dirt suction. To perform each of the movement and the dirt suction functions, at least two motors are required to drive the current swimming pool cleaning robots. This results in high costs for the swimming pool cleaning robots.

Characteristic of the Present Disclosure

According to the present disclosure, in the flow channel, two flow sub-channels are provided, and orientations of water outlets of the two flow sub-channels are opposite. In this way, during use, two impellers may be respectively disposed in the two flow sub-channels, and the two impellers can be driven by corresponding driving motors. When one of the driving motors drives a corresponding impeller to rotate in a specific direction, blades of the impeller force water to enter a corresponding flow sub-channel, so that the impeller continuously pumps water in a swimming pool to the corresponding flow sub-channel through the water inlet. The pumped water generates negative pressure inside the swimming pool cleaning robot to suck up sludge. At the same time, the water pumped in by the impeller can be ejected through the water outlet of the corresponding flow sub-channel, generating a reverse thrust on the swimming pool cleaning robot. The swimming pool cleaning robot can move under the action of the thrust. When the cleaning robot moves to a pool wall or encounters an obstacle, the operating driving motor stops operation, and the other driving motor starts to drive a corresponding impeller to rotate. In this case, water flows into the other flow sub-channel and is ejected from water outlet of the flow sub-channel, so that the swimming pool cleaning robot moves in an opposite direction, to clean the entire pool bottom.

Therefore, in this solution, waterjet propulsion drives the swimming pool cleaning robot to move. In addition, the function of dirt suction can be performed while the swimming pool cleaning robot is driven to move. In this case, only two motors are needed to implement the functions of moving and dirt suction, thereby greatly reducing costs of the swimming pool cleaning robot.

The present disclosure provides a flow channel 10, a driving structure 100, and a swimming pool cleaning robot 1000, to reduce costs of swimming pool cleaning robot 1000.

Specific structures of the flow channel 10, the driving structure 100, and the swimming pool cleaning robot 1000 in the present disclosure are described below.

Refer to FIG. 1, FIG. 2, and FIG. 8. In an embodiment of the flow channel 10 in the present disclosure, the flow channel 10 includes two flow sub-channels 11. A water inlet 11a is provided at the bottom of the flow sub-channel 11. A water outlet 11b is provided at a side of the flow sub-channel 11. Orientations of the water outlets 11b of the two flow sub-channels 11 are opposite. The two flow sub-channels 11 are symmetrical with respect to a center.

It can be understood that, in the flow channel 10 provided in the present disclosure, the two flow sub-channels 11 are provided, and the orientations of the water outlets 11b of the two flow sub-channels 11 are opposite. In this way, during use, two impellers 20 may be separately disposed in the two flow sub-channels 11, and the two impellers 20 may be driven by corresponding driving motors 30. When one of the driving motors 30 drives a corresponding impeller 20 to rotate in a specific direction, blades of the impeller 20 force water to enter a corresponding flow sub-channel 11, so that the impeller 20 continuously pumps water in a swimming pool to the corresponding flow sub-channel 11 through the water inlet 11a. The pumped water generates negative pressure inside the swimming pool cleaning robot 1000 to suck up sludge. At the same time, the water pumped in by the impeller 20 can be ejected through the water outlet 11b of the corresponding flow sub-channel 11, generating a reverse thrust on the swimming pool cleaning robot 1000. The swimming pool cleaning robot 1000 can move under the action of the thrust. When the cleaner moves to a pool wall or encounters an obstacle, the operating driving motor 30 stops operation, and the other driving motor 30 starts to drive a corresponding impeller 20 to rotate. In this case, water flows into the other flow sub-channel 11 and is ejected from the water outlet 11b of the flow sub-channel 11, so that the swimming pool cleaning robot 1000 moves in an opposite direction, to clean the entire pool bottom.

Therefore, in this solution, waterjet propulsion drives the swimming pool cleaning robot 1000 to move. In addition, the function of dirt suction can be performed while the swimming pool cleaning robot 1000 is driven to move. In this case, only two motors 30 are needed to implement the functions of moving and dirt suction, thereby greatly reducing costs of the swimming pool cleaning robot 1000.

In addition, the two flow sub-channels 11 are symmetrical with respect to a center, in other words, the two flow sub-channels 11 are on a same horizontal plane. In this case, two opposite thrusts are generated due to waterjet propulsion from the water outlets 11b of the two flow sub-channels 11, facilitating control over movement of the swimming pool cleaning robot 1000. Further, the overall height of the swimming pool cleaning robot 1000 is reduced because the two flow sub-channels 11 are on the same horizontal plane. This improves stability of the swimming pool cleaning robot 1000 during movement.

Certainly, the two driving motors 30 may alternatively be activated simultaneously. When rotation speeds of both driving motors 30 are the same, the two impellers 20 are respectively driven by the two driving motors 30, generating two opposite thrusts on the swimming pool cleaning robot 1000 that cancel each other out. In this case, the swimming pool cleaning robot 1000 stops moving and sucks sludge during rotation of the two impellers 20. When the rotation speeds of the two driving motors 30 are different, an impeller 20 driven by the faster driving motor 30 rotates at a higher speed. In this case, while moving, the swimming pool cleaning robot 1000 can suck sludge during rotation of the two impellers 20. In this way, cleaning efficiency is improved.

It should be noted that the flow channel 10 provided in this solution is a solid structure, similar to a solid structure like a conduit. In some embodiments, each flow sub-channel 11 may include a bottom plate, a top plate, and a side wall, and bottom plates of the two flow sub-channels 11 may form an integrally formed structure. Similarly, top plates of the two flow sub-channels 11 may also form an integrally formed structure. In some embodiments, the bottom plate of the flow sub-channel 11 may be a partial structure of a main body of the swimming pool cleaning robot 1000 or may be integrated with the main body, as long as an opening (a water exit) communicating with the water inlet 11a of the flow sub-channel 11 are need on the main body.

Further, refer to FIG. 2 and FIG. 8. In an embodiment of the flow channel 10 in the present disclosure, the flow sub-channel 11 includes a volute-shaped inlet section 111 and a curved outlet section 112 that are connected to each other. The water inlet 11a is disposed at the bottom of the volute-shaped inlet section 111. The water outlet 11b is disposed on a side of the curved outlet section 112.

In this design, when the driving motor 30 drives the corresponding impeller 20 to rotate, the impeller 20 continuously draws water in a swimming pool through the water inlet 11a of the volute-shaped inlet section 111 and ejects the water into the corresponding flow sub-channel 11. The water then flows through the volute-shaped inlet section 111 into the curved outlet section 112, and is finally ejected from the water outlet 11b of the curved outlet section 112. In this process, a reverse thrust is generated on the swimming pool cleaning robot 1000. In this process, as the water sequentially flows through the volute-shaped inlet section 111 and the curved outlet section 112, strength of the thrust on the swimming pool cleaning robot 1000 would be effectively increased, improving the movement speed of the swimming pool cleaning robot 1000 and the pool cleaning efficiency.

For example, in order to reduce resistance to the water in the flow channel 10, the volute-shaped inlet section 111 and the curved outlet section 112 are connected by an arc transition.

Further, refer to FIG. 2. In an embodiment of the flow channel 10 in the present disclosure, the volute-shaped inlet section 111 includes a first flow section 1111, a second flow section 1112, and a third flow section 1113. The first flow section 1111, the second flow section 1112, and the third flow section 1113 are connected in sequence in a water flow direction. The first flow section is provided with the water inlet 11a. A radius of curvature of the first flow section 1111 is defined as R1; a radius of curvature of the second flow section 1112 is defined as R2; and the radius of curvature of the third flow section 1113 is defined as R3, where R1, R2, and R3 satisfy a condition: R1≤R2<R3.

In this design, the radius of curvature of the first flow section 1111 is less than or equal to the radius of curvature of the second flow section 1112, and the radius of curvature of the second flow section 1112 is less than or equal to the radius of curvature of the third flow section 1113, the resistance to the water in the flow channel 10 can be effectively reduced in a process of sequentially flowing through the first flow section 1111, the second flow section 1112, and the third flow section 1113. In this way, the water can be ejected from the corresponding water outlet 11b with a greater force to improve the output efficiency, so as to provide a stronger driving force for the swimming pool cleaning robot 1000 and increase the thrust on the swimming pool cleaning robot 1000. Consequently, the moving speed of the swimming pool cleaning robot 1000 is improved.

Further, refer to FIG. 2. In an embodiment of the flow channel 10 in the present disclosure, the radius of curvature of the first flow section 1111 is defined as R1, where R1 satisfies a condition: 21 mm≤R1≤30 mm. In this design, by setting the radius of curvature of the first flow section 1111 to a value from 21 mm to 30 mm, the resistance to the water in the flow channel 10 can be effectively reduced. In this way, the thrust on the swimming pool cleaning robot 1000 is effectively increased.

Similarly, the radius of curvature of the second flow section 1112 is defined as R2, where R2 satisfies a condition: 30 mm≤R2≤36 mm. In this design, by setting the radius of curvature of the second flow section 1112 to a value from 30 mm to 36 mm, the resistance to the water in the flow channel 10 can be effectively reduced. In this way, the thrust on the swimming pool cleaning robot 1000 is also effectively increased.

Similarly, the radius of curvature of the third flow section 1113 is defined as R3, where R3 satisfies a condition: 36 mm≤R3≤50 mm. In this design, by setting the radius of curvature of the third flow section 1113 to a value from 36 mm to 50 mm, the resistance to the water in the flow channel 10 can be effectively reduced. In this way, the thrust on the swimming pool cleaning robot 1000 is also effectively increased.

In some embodiments, an outer diameter of the impeller 20 is defined as R4, and the outer diameter of the impeller 20 may be larger than the radius of curvature of the first flow section 1111 and the radius of curvature of the second flow section 1112, so that the water can be smoothly drawn into the corresponding flow sub-channel 11 during rotation of the impeller 20. Specifically, the outer diameter R4 of the impeller 20 can be set to 40 mm.

Further, refer to FIG. 1, FIG. 2, and FIG. 8. In an embodiment of the flow channel 10 in the present disclosure, the flow channel 10 further includes two guide plates 12. Each of the guide plates 12 is disposed in one of the flow sub-channels 11 and close to the water outlet 11b of the flow sub-channel 11.

In this design, by disposing the guide plate 12 in the corresponding flow sub-channel 11, the water can quickly be ejected from the corresponding water outlet 11b under the action of the guide plate 12 after entering the corresponding flow sub-channel 11, which can further reduce the resistance to the water in the flow channel 10. In this way, the water can be ejected from the corresponding water outlet 11b with a greater force to improve the output efficiency, so as to provide a stronger driving force for the swimming pool cleaning robot 1000.

For example, the guide plate 12 may be integrated to the bottom plate and/or top plate of the corresponding flow sub-channel 11, or may be fastened to the bottom plate and/or top plate of the corresponding flow sub-channel 11 by a screw, a buckle, an adhesive, or the like.

Refer to FIG. 1 to FIG. 8. The present disclosure further provides a driving structure 100. The driving structure 100 includes two impellers 20, two driving motors 30, and the flow channel 10 described above. For a specific structure of the flow channel 10, refer to the foregoing embodiments. As all the technical solutions in the foregoing embodiments are applied to the driving structure 100, the driving structure 100 has at least all the beneficial effects brought by the technical solutions in the foregoing embodiments. The details are not repeated herein. Each impeller 20 is disposed in one of the flow sub-channels 11 and close to the water inlet 11a of the flow sub-channel 11. Each driving motor 30 is drivingly connected to one of the impellers 20 to drive the impeller 20 to rotate.

It should be understood that, during use of the driving structure 100 provided in the present disclosure, the two impellers 20 may be separately disposed in the two flow sub-channels 11, and the two impellers 20 can be driven by corresponding driving motors 30. When one of the driving motors 30 drives the corresponding impeller 20 to rotate in a specific direction, blades of the impeller 20 force water to enter the corresponding flow sub-channel 11, so that the impeller 20 continuously pumps water in a swimming pool to the corresponding flow sub-channel 11 through the water inlet 11a. The pumped water stream generates negative pressure inside the swimming pool cleaning robot 1000 to suck up sludge. At the same time, the water pumped in by the impeller 20 can be ejected through the water outlet 11b of the corresponding flow sub-channel 11, generating a reverse thrust on the swimming pool cleaning robot 1000. The swimming pool cleaning robot 1000 can move under the action of the thrust. When the cleaner moves to a pool wall or encounters an obstacle, the operating driving motor 30 stops operation, and the other driving motor 30 starts to drive a corresponding impeller 20 to rotate. In this case, water flows into the other flow sub-channel 11 and is ejected from the water outlet 11b of the flow sub-channel 11, so that the swimming pool cleaning robot 1000 moves in an opposite direction, to clean the entire pool bottom.

Therefore, in this solution, waterjet propulsion drives the swimming pool cleaning robot 1000 to move. In addition, the function of dirt suction can be performed while the swimming pool cleaning robot 1000 is driven to move. In this case, only two motors 30 are needed to implement the functions of moving and dirt suction, thereby greatly reducing costs of the swimming pool cleaning robot 1000.

In practical application, the driving motor 30 may be located in the corresponding flow sub-channel 11 to drive the corresponding impeller 20 to rotate; Alternatively, the driving motor 30 may be located outside the corresponding flow sub-channel 11, so that an output shaft of the driving motor 30 extends into the corresponding flow sub-channel 11, further driving the corresponding impeller 20 to rotate. Certainly, in some embodiments, to facilitate maintenance of the driving motor 30 and prevent damage from the water to the driving motor 30, the driving motor 30 may be disposed outside the corresponding flow sub-channel 11, so that the output shaft of the driving motor 30 extends into the corresponding flow sub-channel 11, further driving the corresponding impeller 20 to rotate.

In practical application, the impeller 20 can be disposed near the water inlet 11a, between the water inlet 11a and the water outlet 11b, or near the water outlet 11b, as long as water can be continuously drawn from the pool through the water inlet 11a to the corresponding flow sub-channel 11 during rotation of the impeller 20. Certainly, in some embodiments, the impeller 20 may be disposed near the water inlet 11a to ensure pumping intensity, so that the water can be quickly drawn into the corresponding flow sub-channel 11 under the action of the impeller 20.

Further, refer to FIG. 3 and FIG. 5. In an embodiment of the driving structure 100 in the present disclosure, the bottom of the impeller 20 is provided with a water entry 20a, and a side of the impeller 20 is provided with a drainage outlet 20b. The water entry 20a is connected to the water inlet 11a, and the drainage outlet 20b is connected to the water outlet 11b.

In this design, when the driving motor 30 drives the impeller 20 to rotate, the water can enter the impeller 20 through the water entry 20a at the bottom of the impeller 20, and then the water is discharged into the corresponding flow sub-channel 11 through the drainage outlet 20b on the side of the impeller 20. In this way, the output efficiency can be improved because the water ejected from the impeller 20 driven by the driving motor 30 can be ejected from the water outlet 11b with a greater force, thereby providing a stronger driving force for the swimming pool cleaning robot 1000.

For example, for ease of mounting the impeller 20 and the driving motor 30, the bottom of the impeller 20 penetrates the water inlet 11a of the flow sub-channel 11 to fasten the impeller 20, and a mounting groove is further provided at the bottom of the impeller 20. Then, the output shaft of the driving motor 30 can be inserted into the mounting groove at the bottom of the impeller 20, so that rotation of the output shaft of the driving motor 30 smoothly drives the impeller 20 to rotate.

In some embodiments, the mounting groove may be disposed in the center of the bottom of the impeller 20, and the water entry 20a of the impeller 20 may surround the mounting groove, so that the water can be quickly drawn into the corresponding flow sub-channel 11 during rotation of the impeller 20.

Further, refer to FIG. 2. In one embodiment, a gap between an outer wall of the impeller 20 and an inner wall of the flow sub-channel 11 is defined as L, where L satisfies a condition: L≥1 mm. This ensures that water discharged from the drainage outlet 20b on the side of the impeller 20 can enter the flow sub-channel 11 through the gap between the impeller 20 and the inner wall of the flow sub-channel 11, to avoid significant resistance to the water caused by a narrow gap between the impeller 20 and the inner wall of the flow sub-channel 11.

Further, refer to FIG. 5. In one embodiment of the driving structure 100 in the present disclosure, the driving structure 100 further includes a sealed chamber 40, and the driving motor 30 is disposed inside the sealed chamber 40. The output shaft of the driving motor 30 extends beyond the sealed chamber 40 and into the flow sub-channel 11, so as to drivingly connected to the impeller 20.

In this design, the driving motor 30 is disposed inside the sealed chamber 40. In this way, water in the swimming pool cannot enter the driving motor 30, and therefore a service life of the driving motor 30 is not affected.

Referring to FIG. 4 to FIG. 8, the present disclosure further provides a swimming pool cleaning robot 1000. The swimming pool cleaning robot 1000 includes a main body and the flow channel 10 described above, or includes a main body and the driving structure 100 described above. For a specific structure of the flow channel 10 or the driving structure 100, referring to the foregoing embodiments. As all the technical solutions in the foregoing embodiments are applied to the swimming pool cleaning robot 1000, the swimming pool cleaning robot 1000 has at least all the beneficial effects brought by the technical solutions in the foregoing embodiments. The details are not repeated herein. The flow channel 10 is disposed on the main body. Alternatively, the driving structure 100 is disposed on the main body.

In some embodiments, the main body may include a housing 200 and a filter (not shown in the figure) inside the housing 200. The housing 200 may be provided with a water intake (not shown in the figure) and a water exit (not shown in the figure). The filter covers the water intake. The water enters through the water intake, passes through the filter, and enters the impeller 20 through the water exit. Consequently, sludge is filtered out by the filter and left in a garbage room of the housing. When one of the driving motors 30 drives the corresponding impeller 20 to rotate in a specific direction, the water in the swimming pool may first enter the housing 200 through the water intake, and then the filter filters the water. The filtered water can enter the impeller 20 through the water exit, and then the impeller 20 forces the water to enter the corresponding flow sub-channel 11. Finally, the water is ejected from the water outlet 11b of the flow sub-channel 11, and a reverse thrust is generated on the swimming pool cleaning robot 1000. Under the action of the thrust, the swimming pool cleaning robot 1000 starts moving, that is, the water can flow out along a dashed line a in FIG. 5. In this way, sludge is sucked as the swimming pool cleaning robot 1000 is driven to move.

Further, to facilitate stable movement of the swimming pool cleaning robot 1000, a roller 300 may be installed at the bottom of the housing 200. When the swimming pool cleaning robot 1000 is propelled by ejected water, the roller 300 can assist the swimming pool cleaning robot 1000 to move, so that the swimming pool cleaning robot 1000 can stably move.

Further, there may be a plurality of rollers 300 to maintain the balance of the swimming pool cleaning robot 1000 under the action of the plurality of rollers 300, so that the swimming pool cleaning robot 1000 can move more stably.

For example, for ease of holding the swimming pool cleaning robot 1000, a handle can be provided at the top of the housing 200.

For example, to facilitate mounting of structures inside the housing 200, the housing 200 may include a top cover 220 that is detachably connected to a bottom shell 210. In this way, in an assembly process, the bottom shell 210 can be separated from the top cover 220; the structures such as the filter and the driving structure 100 can be mounted on the bottom shell 210; and the top cover 220 can be placed on the bottom shell 210. In this way, assembly of the entire structure is completed.

Embodiments of the present disclosure are described above, but persons skilled in the art should understand that the present disclosure is not limited to the foregoing embodiments. The foregoing embodiments are merely examples. Embodiments having compositions same as the essence of the technical concepts and embodiments achieve the same functions fall within the technical scope of the present disclosure. Further, various modifications to the embodiments that can be figured out by persons skilled in the art and other forms constructed by combining some elements in the embodiments fall within the scope of the present disclosure, as long as the modifications and the forms do not depart from the scope of the present disclosure.
