Description

Swimming pool cleaning equipment Technical Field

[0001] The present disclosure relates to the technical field of water cleaning, and more particularly to a swimming pool cleaning device. Background Art

[0002] A pool cleaning machine is an automated device used to remove impurities, dirt, and debris from a swimming pool to maintain clean water and sanitation. As it cleans, the machine moves along the pool floor, walls, or surface, drawing water into the machine for filtration and then draining the filtered water back into the pool.

[0003] However, in actual use, it was found that the inlet for sucking in water flow on existing machines is generally set at the bottom of the machine. The advantage of this is that when the machine moves on the bottom and wall of the pool, it can suck in the water flow along the walking path for filtering and cleaning. However, when the machine is cleaning on the water surface, it is necessary to adjust the body of the machine so that the machine is tilted on the water surface and the inlet at the bottom of the machine is kept below the water surface, so that the suction port can more easily contact the water surface and can suck in water flow. However, it is not easy to adjust the machine to such a tilted body, so some existing machines have omitted the function of cleaning the water surface and only retained the function of cleaning the bottom and wall of the pool; in addition, there are also some machines that support water surface cleaning, but it is difficult for the machine to maintain a stable inlet position, resulting in large fluctuations in the water intake of the machine and unsatisfactory cleaning effects.

[0004] It can be seen that the water channel structure of the existing swimming pool cleaning machine needs to be further optimized so that the machine can maintain a normal water intake for water cleaning in various cleaning scenarios.

[0005] Summary of the Invention

[0006] The present disclosure aims to provide a swimming pool cleaning device to solve the technical problem that the water channel structure of the existing swimming pool cleaning machine has unsatisfactory effect in the process of sucking in water flow for filtration in some cleaning scenarios.

[0007] To achieve the above objectives, the technical solutions adopted in this disclosure are:

[0008] The present disclosure provides a swimming pool cleaning device, comprising a body, a filtering mechanism, a fluid pumping mechanism, a water spraying mechanism, and a traveling mechanism. The body is provided with at least one water inlet, the at least one water inlet being in fluid communication with the filtering mechanism. The fluid pumping mechanism provides a suction force for water to flow from the at least one water inlet to the water spraying mechanism, and the water that has passed through the filtering mechanism flows out of the body from the water spraying mechanism. The at least one water inlet comprises: a first water inlet disposed at the bottom of the body; and a second water inlet disposed at the side of the body. When the device is in a first cleaning state, water is pumped from the first water inlet to the filtering mechanism, and after passing through the filtering mechanism, is sprayed from the water spraying mechanism in a first direction, the first direction being at an angle to the traveling direction of the swimming pool cleaning device. When the device is in a second cleaning state, water is pumped from the second water inlet to the filtering mechanism, and after passing through the filtering mechanism, is sprayed from the water spraying mechanism in a second direction, the second direction being substantially parallel to the traveling direction of the swimming pool cleaning device.

[0009] In some optional schemes, a first flow channel is provided between the first water inlet and the filtering mechanism, and a second flow channel is provided between the second water inlet and the filtering mechanism, wherein the first flow channel and the second flow channel are opened selectively; when the device is in the first cleaning state, the first flow channel is opened and the second flow channel is closed; when the device is in the second cleaning state, the second flow channel is opened and the first flow channel is closed.

[0010] The swimming pool cleaning device provided by the present disclosure has at least the following beneficial effects: first, a first water inlet and a second water inlet are respectively provided on the bottom and side of the body. This allows the device to draw water from the first water inlet at the bottom for filtration when cleaning the pool bottom or pool wall, and also allows the device to draw water from the second water inlet at the side for filtration when cleaning the water surface, without having to adjust the body posture to align the bottom water inlet with the water flow. This not only makes it easier for the device to draw water at the water surface, but also more effectively draws in garbage on the water surface. Second, the direction in which the water drawn into the device is discharged through the water spray mechanism after filtration is adapted to the cleaning scenario of the device. When the device is cleaning the pool bottom or pool wall, the water spray direction is roughly perpendicular to the device's travel direction, and the reverse thrust generated by the water spray provides downward pressure on the device, allowing the device to cling to the pool bottom or pool wall. When the device is cleaning the pool surface, the water spray direction is roughly parallel to the device's travel direction, and the reverse thrust generated by the water spray provides propulsion to the device, allowing the device to move on the water surface, thereby improving the device's movement performance.

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present disclosure more clearly understood, the present disclosure is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0035] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be located directly or indirectly on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on this technical solution. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0036] In some embodiments, as shown in FIG1 , an embodiment of the present disclosure provides a swimming pool cleaning device 1 (hereinafter referred to as the device) comprising: a body 11, a filtering mechanism 12, a fluid pumping mechanism 13, a water spraying mechanism 14, and a walking mechanism 15. The body 11 is provided with at least one water inlet, which is in fluid communication with the filtering mechanism 12. The fluid pumping mechanism 13 provides a suction force for water flow from the at least one water inlet to the water spraying mechanism 14. The water flow passing through the filtering mechanism 12 flows out of the body 11 from the water spraying mechanism 14. The at least one water inlet includes: a first water inlet 111, which is provided at the bottom of the body 11; a second water inlet The inlet 112 is provided on the side of the body 11. When the device is in a first cleaning state, such as when cleaning the pool bottom or pool wall, water is sucked into the filter mechanism 12 through the first water inlet 111 and, after passing through the filter mechanism 12, is sprayed out from the water spray mechanism 14 in a first direction P1. The first direction P1 is substantially perpendicular to the travel direction M of the pool cleaning device 1. When the device is in a second cleaning state, such as when cleaning the water surface, water is sucked into the filter mechanism 12 through the second water inlet 112 and, after passing through the filter mechanism 12, is sprayed out from the water spray mechanism 14 in a second direction P2. The second direction P2 is substantially parallel to the travel direction M of the pool cleaning device 1.

[0037] In some embodiments, the first direction P1 forms an angle with the device's operating direction M, with the angle being between 0 and 180 degrees. To provide sufficient downward pressure on the device in the first cleaning state, the angle can be between 45 and 135 degrees. In more common scenarios, when the device is traveling along the bottom or wall of the pool, the travel mechanism 15 can provide the device with driving force, and the angle can be set to 90±10 degrees. In the above situations, the direction of the water jet provides a certain reaction force for the device. The reaction force perpendicular to the device's direction of travel can make the device close to the surface to be cleaned, thereby increasing the friction between the travel mechanism and the surface to be cleaned. The reaction force parallel to the device's direction of travel provides a certain amount of auxiliary power to the device, increasing or decreasing the device's traction force.

[0038] In some embodiments, the second direction P2 is substantially parallel to or angled with the device's operating direction M. This angle can be set to 0-30° or 150-180°, such as 180° in FIG1 . At this angle, the water jet generates a reaction force, with the component of this reaction force parallel to the direction of travel M being greater than the component perpendicular to the direction of travel M. This reaction force can be understood as primarily providing propulsion power for the device in the second cleaning state.

[0039] In some embodiments, there may be two water inlets, the first water inlet 111 being arranged at the bottom of the machine body, and the second water inlet 112 being arranged at the side of the machine body.

[0040] The beneficial effects of the above-mentioned swimming pool cleaning device 1 are as follows: first, by providing the first and second water inlets on the body 11, the device can be used to extract water from the first water inlet 111 at the bottom of the body 11 for filtration when cleaning the pool bottom or pool wall, and can also be used to extract water from the second water inlet 112 on the side of the body 11 at the front of the water surface in the direction of operation of the device for filtration when cleaning the water surface, without having to adjust the posture of the body 11 to align the bottom water inlet with the water flow. This not only makes it easier for the device to inhale water on the water surface, but also allows it to inhale more effectively. Garbage on the water surface; secondly, the direction in which the water flow sucked into the equipment is discharged through the water spraying mechanism 14 after filtration is adapted to the cleaning state of the equipment. In the first cleaning state, for example, when the equipment cleans the bottom or wall of the pool, the water spraying direction and the equipment moving direction can be roughly perpendicular, and the reverse thrust generated by the water spraying provides downward pressure on the equipment, so that the equipment can stick to the bottom or wall of the pool. In the second cleaning state, for example, when the equipment cleans the pool surface, the water spraying direction and the equipment moving direction can be roughly parallel, and the reverse thrust generated by the water spraying provides propulsion to the equipment, so that the equipment moves on the water surface, thereby improving the movement performance of the equipment.

[0041] The body 11 is the main structure of the device, including but not limited to the body shell, for example, the bottom shell and the outer shell. The bottom shell is located at the bottom of the device and is used to install components such as the walking mechanism 15. The outer shell is located above the device and generally serves as the appearance of the device, and also plays the role of covering or sealing the internal structure of the device.

[0042] The running mechanism 15 enables the pool cleaning device 1 to move along a specific path or direction in the water. In practice, the user can set the device's travel direction via a remote control or automated program, ensuring that the device covers the entire pool surface and bottom. Generally, the running mechanism 15 can be a tracked running mechanism, consisting of two or more tracks, typically located at the bottom of the device. These tracks are driven by an electric motor, enabling the device to move across the pool surface or bottom. Alternatively, the running mechanism 15 can be a wheeled running mechanism, typically including two or four wheels, either conventional or airbag-type. The motor drives the wheels, thereby propelling the device within the pool. Furthermore, some advanced running mechanisms are equipped with navigation systems, including but not limited to sensors, cameras, or lidar, to help the device perceive its surroundings. This allows the device to avoid obstacles and follow a predetermined cleaning path, thereby improving cleaning efficiency. Of course, in practice, the running mechanism 15 can also be implemented with other structures, and this is not limited in the present embodiment.

[0043] Since there is more than one water inlet, each adapted to a different cleaning state of the device, when the device is in a different cleaning state, only the corresponding water inlet needs to be opened to draw water in, while the other water inlets remain closed. Considering that the water inlets are fluidically connected to the filter mechanism 12, a corresponding flow channel is typically provided between the two. Therefore, by opening and closing the water inlets, or by blocking / opening the flow channel corresponding to each water inlet, water can be drawn in from the corresponding water inlet, allowing the water to enter the filter mechanism 12 for filtration. This embodiment uses the blocking / opening flow channel method for detailed description.

[0044] As shown in Figure 2, in some embodiments, a first flow channel 161 is provided between the first water inlet 111 and the filtering mechanism 12, and a second flow channel 162 is provided between the second water inlet 112 and the filtering mechanism 12. The first flow channel 161 and the second flow channel 162 are opened selectively, wherein the device is in the first cleaning state, such as when the pool bottom / pool wall is cleaned, the first flow channel 161 is opened and the second flow channel 162 is closed; the device is in the second cleaning state, such as when the water surface is cleaned, the second flow channel 162 is opened and the first flow channel 161 is closed.

[0045] Specifically, the first flow channel 161 and the second flow channel 162 can be flexible flow channels or rigid flow channels. If they are flexible flow channels, the first flow channel 161 and the second flow channel 162 include hoses or telescopic tubes. If they are rigid flow channels, the first flow channel 161 and the second flow channel 162 can be made of materials such as plastic, metal or alloy. Compared with flexible flow channels, rigid flow channels are less likely to age and deform during long-term use and have better durability; and the inner wall of the rigid flow channel is relatively smooth and less likely to form water flow resistance, which helps to maintain a high water flow efficiency. In this embodiment, the first flow channel 161 and the second flow channel 162 are rigid flow channels.

[0046] In actual applications, there is no single specific implementation for selectively opening the first flow channel 161 and the second flow channel 162 .

[0047] In some embodiments, as shown in Figures 3A and 3B , a flow channel regulating device 17 is provided near the first flow channel 161 and the second flow channel 162. The flow channel regulating device 17 includes: at least one drive motor 171 and at least one baffle 172. The drive motor 171 is in transmission connection with the baffle 172, and is configured to drive the at least one baffle 172 to selectively cut off the first flow channel 161 and the second flow channel 162. When there are multiple drive motors 171, each motor drives at least one baffle 172 to move. For example, when there are two baffles, two drive motors 172 can be used to respectively drive the two baffles to rotate and / or translate.

[0048] In FIG3A , there is one baffle 172 . The drive motor 171 has an output shaft for outputting rotational power. The baffle 172 is connected to the output shaft of the drive motor. When the drive motor 171 rotates, it drives the baffle 172 to rotate around the output shaft. When the baffle 172 rotates to the first position (position A in FIG3A ), the baffle 172 cuts off the first flow channel 161, while the second flow channel 162 is unobstructed. In FIG3B , when the baffle 172 rotates to the second position (position B in FIG3B ), the baffle 172 cuts off the second flow channel 162, while the first flow channel 161 is unobstructed. Here, the first position includes the position where the baffle 172 cuts off the first flow channel 161, and the second position includes the position where the baffle 172 cuts off the second flow channel 162. The drive motor drives the baffle 172 to rotate between the first position and the second position, and one of the flow channels is always in a cut-off state, thereby achieving the effect of selectively cutting off the first and second flow channels 162.

[0049] In some actual usage scenarios, in combination with Figures 1 and 3, when the swimming pool cleaning device 1 is working at the bottom or wall of the pool, the device controls the drive motor 171 to rotate the baffle 172 to the second position, cuts off the second flow channel 162, and opens the first flow channel 161 downstream of the first water inlet 111. At this time, the water flow can only enter the filter mechanism 12 from the first water inlet 111 along the first flow channel 161, and the filter mechanism 12 filters the water flow and discharges clean water; when the swimming pool cleaning device 1 is working on the water surface, the drive motor 171 is controlled to rotate the baffle 172 to the first position, cuts off the first flow channel 161, and opens the second flow channel 162 downstream of the second water inlet 112. At this time, the water flow can only enter the filter mechanism 12 from the second water inlet 112 along the second flow channel 162, and the filter mechanism 12 filters the water flow and discharges clean water.

[0050] The embodiment of the present disclosure drives a baffle 172 to rotate by a driving motor 171 to selectively cut off one of the two flow channels, which is equivalent to selecting a corresponding water inlet to close and opening the other water inlet to adapt to the cleaning of the equipment at different positions, so that the equipment can more easily suck in water from the open water inlet for filtering, thereby optimizing the water path mechanism of the equipment. At the same time, the structure of driving the baffle 172 to rotate and cut off the flow channel is very simple, easy to implement and low-cost.

[0051] In addition, the number of baffles 172 can also be two. In some flow channel regulating devices 17, a driving motor 171 can be connected to the two baffles 172 to drive the two baffles 172 to move in translation to select one to cut off the flow channel, or a driving motor 171 can simultaneously drive one baffle 172 to rotate and the other baffle 172 to move in translation to select one to cut off the flow channel.

[0052] In some flow channel regulating devices, in combination with Figures 4 and 5, there is one drive motor 171 and two baffles 172, including a first baffle 172a and a second baffle 172b. The first baffle 172a is connected to the output shaft of the drive motor 171, and the second baffle 172b is connected to the output shaft of the drive motor through a first transmission mechanism. When the drive motor 171 rotates, it drives the first baffle 172a to rotate around the output shaft, and at the same time drives the second baffle 172b to reciprocate along a straight line through the first transmission mechanism. When the first baffle 172a rotates to the first position, the first baffle 172a cuts off the first flow channel 161, and the second baffle 172b opens the second water inlet 112. At this time, the second flow channel 162 is unobstructed; when the baffle rotates to the second position, the first baffle 172a cuts off the second flow channel 162, and the second baffle 172b covers the second water inlet 112. At this time, the first flow channel 161 is unobstructed.

[0053] Here, the first position includes the position where the first baffle 172a cuts off the first flow channel 161 and the position where the second baffle 172b opens the second water inlet 112, namely, position A and position C in Figure 4; and the second position includes the position where the first baffle 172a cuts off the second flow channel 162 and the second baffle 172b covers the second water inlet 112, namely, position B and position D in Figure 5.

[0054] The specific implementation of the first transmission mechanism is not unique. In this embodiment, the function of the first transmission mechanism is to convert the rotational motion of the drive motor 171 into linear motion. Therefore, any transmission structure that can convert rotational motion into linear motion can be used as the first transmission mechanism.

[0055] For example, as shown in Figure 5, in some embodiments, the first transmission mechanism includes: a synchronous transmission assembly, a first gear assembly and a linear transmission assembly. One end of the synchronous transmission assembly is transmission-connected to the output shaft of the drive motor 171, and the other end is transmission-connected to the first gear assembly, synchronously transmitting the rotation of the drive motor 171 to the first gear assembly. The linear transmission assembly is engaged with the first gear assembly and is used to convert the rotational motion of the first gear assembly into linear motion. The second baffle 172b is fixedly connected to the linear transmission assembly. When the drive motor 171 rotates, the second baffle 172b moves back and forth in the direction of the linear motion. For example, in FIG5 , the synchronous transmission assembly includes two synchronous pulleys 1731 and a synchronous belt 1732, the first gear assembly includes two gears, one of which is a driving pulley 1733 and the other is a driven pulley 1734, and the linear transmission assembly includes a rack 1735; wherein, one synchronous pulley 1731 is connected to the output shaft of the drive motor, and the other synchronous pulley 1731 is meshed with the driving pulley 1733, the synchronous belt 1732 is sleeved on the two synchronous pulleys 1731, and the driven pulley 1734 is respectively connected to the output shaft of the drive motor 1731 and the driven pulley 1734. They are respectively engaged with the driving wheel 1733 and the rack 1735. When the driving motor 171 rotates, the two synchronous pulleys 1731 are driven to rotate synchronously. The synchronous pulley 1731 drives the driving wheel 1733 to rotate, and the driving wheel 1733 drives the driven wheel 1734 to rotate, and the driven wheel 1734 drives the rack 1735 to move, thereby converting the rotational motion of the driving motor 171 into linear motion, driving the second baffle 172b connected to the rack 1735 to move back and forth along a straight line, thereby achieving the effect of covering or opening the second water inlet 112.

[0056] In some usage scenarios, when the swimming pool cleaning device is cleaning on the water surface, the device controls the drive motor to drive the first baffle 172a to rotate to position A in Figure 4, and the second baffle 172b moves to position C in Figure 4; when the swimming pool cleaning device is cleaning the bottom or wall of the pool, the device controls the drive motor to drive the first baffle 172a to rotate to position B in Figure 5, and drives the second baffle 172b to move to position D in Figure 5.

[0057] In this embodiment, on the basis of using a driving motor to drive the first baffle 172a to rotate to select a cut-off flow channel, a second baffle 172b is added to move back and forth in a straight line to cover or open the second water inlet 112, so that the second flow channel 162 is cut off and the second water inlet 112 is covered, thereby preventing foreign matter from entering the flow channel space from the second water inlet 112 to the cut-off position of the second flow channel 162, thereby reducing the risk of the flow channel being blocked.

[0058] In one embodiment, as shown in FIG6 , in some flow channel regulating devices, there is one drive motor with two output shafts, and two baffles, including a third baffle 172 c and a fourth baffle 172 d. A second transmission mechanism is provided between the drive motor and the two baffles, and the second transmission mechanism is respectively connected to the output shaft of the drive motor and the two baffles. When the drive motor 171 drives the two baffles to move to the first position, the third baffle 172 c opens the first flow channel 161, and the fourth baffle 172 d cuts off the second flow channel 162 / the second water inlet 112. At this time, the first water inlet 111 and the first flow channel 161 are in fluid communication with the filtering mechanism 12. The first position described in this embodiment includes the position where the third baffle 172 c opens the first flow channel 161. The third baffle 172c and the fourth baffle 172d cut off the second flow channel 162 / the second water inlet 112; when the driving motor 171 drives the two baffles to move to the second position, the third baffle 172c cuts off the first flow channel 161, and the fourth baffle 172d opens the second flow channel 162 / the second water inlet 112. At this time, the second water inlet 112 and the second flow channel 162 are fluidically connected to the filtering mechanism 12. The second position described in this embodiment includes the position where the third baffle 172c cuts off the first flow channel 161 and the position where the fourth baffle 172d opens the second flow channel 162 / the second water inlet 112; wherein the moving directions of the third baffle 172c and the fourth baffle 172d are angled, and the angle is not 0, that is, they are not parallel, and they can be roughly perpendicular to each other.

[0059] The specific implementation of the second transmission mechanism is not unique. The function of the second transmission mechanism illustrated in Figure 6 is to convert the rotational motion of the drive motor 171 into linear motion in two approximately perpendicular directions. Therefore, as long as the transmission structure has this function, it can be used as the second transmission mechanism, and the embodiments of the present disclosure do not limit this.

[0060] In some embodiments, in conjunction with Figures 6 and 7, the second transmission mechanism includes: a second gear assembly and a rotating shaft 1741, the second gear assembly includes four gears, namely a first cylindrical gear 1742, a second cylindrical gear 1743, a third cylindrical gear 1744 and a fourth cylindrical gear 1745, the first cylindrical gear 1742, the second cylindrical gear 1743 and the third cylindrical gear 1744 are respectively connected to the two ends and the middle position of the rotating shaft 1741, and the fourth cylindrical gear 1745 is connected to the shaft. On the output shaft of motor 171, first and second cylindrical gears 1742 and 1743 respectively mesh with first racks 1721 on either side of third baffle 172c. Third cylindrical gear 1744 meshes with second rack 1722 and fourth cylindrical gear 1745 on fourth baffle 172d. When the motor rotates, it drives third and fourth baffles 172c and 172d to move linearly in sync, with the directions of travel of the third and fourth baffles 172c and 172d being approximately perpendicular to each other. The third baffle 172c is provided with two rows of first racks 1721, spaced parallel to and arranged on either side of the third baffle 172c. A hollow portion is formed between the two rows of first racks 1721. A row of second racks 1722 is provided in the middle of one side of the fourth baffle 172d. In addition, the first cylindrical gear 1742 , the second cylindrical gear 1743 , the third cylindrical gear 1744 , and the fourth cylindrical gear 1745 include, but are not limited to, spur gears and helical gears.

[0061] In some usage scenarios, when the device is cleaning the bottom or wall of the pool, the drive motor is controlled to rotate in a first direction, for example, counterclockwise, to drive the third baffle 172c and the fourth baffle 172d to move to the first position, open the first water inlet 111 and the first flow channel 161, and close the second water inlet 112 / second flow channel 162; when the device is cleaning on the water surface, the drive motor is controlled to rotate in a second direction, for example, clockwise, to drive the third baffle 172c and the fourth baffle 172d to move to the second position, open the second water inlet 112 and the second flow channel 162, and close the first water inlet 111 and the first flow channel 161, so as to achieve the selective cutoff of the first flow channel and the second flow channel, thereby realizing the cleaning of the device at different cleaning positions; and compared with the above-mentioned rotation method to select a cutoff flow channel, the method of the baffle translationally cutting off the flow channel is more stable and reliable.

[0062] In some embodiments, a passively openable and closable first door stop is provided at the first water inlet 111 or in the first flow channel 161, and is in a normally closed state; a driven second door stop is provided at the second water inlet 112 or in the second flow channel 162. The second door stop can be driven by a motor. When the cleaning device is cleaning the pool bottom or wall, the second gate blocks the second water inlet 112 or closes the second flow channel 162. The first gate can be opened by the fluid pumping device, and the dust-laden water flow near the first water inlet 111 passes through the first water inlet 111 and the first flow channel 161, thereby entering the filter mechanism for filtration and then being discharged from the body. When the cleaning device is cleaning on the water surface, the second water inlet 112 is partially below the water surface and partially above the water surface. The motor drives the second gate to open, so that the garbage and water near the second water inlet 112 enter the filter mechanism through the second water inlet 112 and the second flow channel 162. At this time, because the fluid pumping device preferentially acts on the second flow channel with lower resistance, the first gate in the first flow channel 161 with higher resistance or at the first water inlet 111 will be closed. In other words, due to the opening of the second flow channel 162, the first gate will remain closed, even if the fluid pumping device is turned on. Through the above arrangement, the overall structure of the device can be simplified while achieving the effect of selectively opening the first and second flow channels.

[0063] Filter mechanism 12 is used to filter impurities, dirt, solid particles, and other debris from the water drawn into the machine, ensuring that the water returned to the pool is clean. In practice, there are many different implementations of filter mechanism 12, with the primary difference being the filtering effect. Below are several examples of filter mechanism 12 that demonstrate excellent filtering effects.

[0064] In some embodiments, as shown in Figure 8, the filtering mechanism 12 includes: a rotary separation filtering device 12A, including: an outer vortex space 121, an inner vortex space 122, a filter screen 123 and a filter screen cleaning device 124. The outer vortex space 121 is located upstream of the filter screen 123, and can make the incoming water flow perform a rotational motion in the outer vortex space 121 to separate part of the garbage from the fluid; the inner vortex space 122 is arranged on the inner side of the filter screen 123, and can make the water flow passing through the filter screen 123 generate a secondary rotational motion in the inner vortex space 122 to secondary separate the garbage and discharge the water flow; the filter screen cleaning device 124 is arranged around the filter screen 123, and is used to clean the garbage attached to the filter screen 123.

[0065] The working principle of the rotary separation filter device 12A is that the water flow sucked in from the water inlet first enters the outer vortex space 121. Due to the inertia of the water flow, the water flow rotates in the outer vortex space 121. Since the size of the garbage is often proportional to the mass, that is, the larger the size of the garbage particles, the greater the mass. The centrifugal force of garbage particles of different masses is different. Large particles of garbage will be thrown to the inner wall of the outer vortex space 121 by the centrifugal force, and then fall to the bottom of the outer vortex space 121 under the action of their own gravity, while other small particles of garbage will pass through the filter mesh 123 with the water flow into the inner vortex space 122, and perform a second rotation motion in the inner vortex space 122. Based on the same principle, the garbage in the water flow will be separated from the water flow due to centrifugal motion, and thus fall to the bottom of the inner vortex space 122. After two rotational separations, the water flow will flow out of the filter mechanism, thereby realizing the filtration of garbage in the water.

[0066] It is worth mentioning that as water flows from the outer vortex space 121 through the filter 123 into the inner vortex space 122, some debris may adhere to the mesh of the filter 123, thereby clogging the mesh and reducing the filtering effect. Therefore, a filter cleaning device 124 is provided in the filter mechanism to clean the debris attached to the filter 123, prevent the mesh from being clogged, and thus ensure the filtering effect. In practice, the specific implementation of the filter cleaning device 124 is not limited.

[0067] In some embodiments, as shown in Figure 9, the filter cleaning device 124 includes an impeller 1241 and a brush bar 1242. The impeller 1241 is arranged at a position where the inlet of the rotary separation filter device is connected to the outer vortex space, and is fixed and rotated along the axial direction of the filter screen 123. The brush bar 1242 is arranged along the axial direction of the filter screen 123 and is tightly attached to the side wall of the filter screen 123. The brush bar 1242 is fixedly connected to the impeller 1241 or the impeller 1241 can drive the brush bar 1242 to rotate. When the water flow rotates in the outer vortex space, the impeller 1241 is driven to rotate, so that the impeller 1241 drives the brush bar 1242 to rotate circumferentially along the side wall of the filter screen 123 to wipe off the garbage on the side wall.

[0068] Impeller 1241 is located at the entrance of the rotary separation filter device, connecting it to the outer vortex space. When water enters, it impacts impeller 1241, leveraging the inertia and rotational motion of the water flow to drive impeller 1241 to rotate. The rotation of impeller 1241 then drives brush bar 1242 to rotate circumferentially around filter screen 123. Because brush bar 1242 clings to the sidewall, it can remove trash particles adhering to filter screen 123, preventing clogging of the mesh of filter screen 123. This shows that the filter screen cleaning device 124 provided in this embodiment has a simple structure and can rotate spontaneously with the water flow to clean filter screen 123, making it highly energy-efficient and environmentally friendly.

[0069] The brush strip 1242 can be strip-shaped and can be at least one in number. The brush strip 1242 can be arranged parallel to, inclined to, or circumferentially along the axis of the filter screen 123. For example, when there is only one brush strip 1242, the brush strip 1242 clings to the outer wall of the filter screen 123, parallel to or inclined to the axis of the filter screen 123. When there are multiple brush strips 1242, the multiple brush strips 1242 are spaced apart in the circumferential direction of the filter screen 123, and cling to the outer wall, parallel to or inclined to the axis of the filter screen 123.

[0070] The shape of the filter 123 includes, but is not limited to, cylindrical, conical, and prismatic shapes. In this embodiment, the shape of the filter 123 is preferably cylindrical. The filter 123 is provided with a plurality of meshes, the size of which can be set according to the specific application scenario and is not limited in this disclosure.

[0071] In some embodiments, the filter cleaning device 124 may be driven actively by a motor, which is more convenient to control and more stable to operate than a passive impeller-driven method.

[0072] In some embodiments, as shown in FIG10 , the filter mechanism 12 includes a first-stage filter mechanism 12B1 and a second-stage filter mechanism 12B2 , which are connected in cascade. The water inlet is in fluid communication with the first-stage filter mechanism 12B1 . The size of the waste separated by the water flowing through the first-stage filter mechanism 12B1 is larger than the size of the waste separated by the water flowing through the second-stage filter mechanism 12B2 . At least one of the first-stage filter mechanism 12B1 and the second-stage filter mechanism 12B2 is a rotary separation filter 12A. In FIG10 , the outlet of the filter mechanism 12 is connected to the fluid pumping mechanism 13 .

[0073] This embodiment filters the water flow drawn in from the water inlet step by step by cascading the first-stage filtering mechanism and the second-stage filtering mechanism. The size of the garbage filtered out of the water flow at each stage becomes smaller and smaller, so that when the water flow passes through the filtering mechanism, the garbage in the water flow is reduced step by step. After passing through the filtering mechanism, the garbage in the water flow is filtered more thoroughly, effectively improving the cleanliness of the water flow after filtration.

[0074] The first-stage filtering mechanism is an inertial separation filtering mechanism, and the second-stage filtering mechanism is a rotary separation filtering device 12A. In practice, there are many specific implementation methods of the inertial separation filtering mechanism.

[0075] In some embodiments, as shown in FIG11 , the first-stage filtration mechanism is an inertial separation filtration mechanism, comprising at least two straight fluid channels 125 and a trash collection chamber 126. The at least two straight fluid channels 125 are vertically arranged along their length above the trash collection chamber 126. The at least two straight fluid channels 125 are arranged side by side, connected end-to-end, and curved. The ends of the connected straight fluid channels 125 are connected to the water inlet and the second-stage filtration mechanism, respectively. The straight fluid channels 125 have openings at the curved connection locations near the trash collection chamber 126. The inner walls of the straight fluid channels 125 surrounding the openings are tapered. This embodiment utilizes the principle of inertia, causing water to flow through the inertial separation filtration mechanism first. Because the inertia of large-sized trash is greater than that of the water flow, the large trash is separated at the bends in the water flow, achieving coarse filtration of the water flow.

[0076] In addition, the specific implementation of the rotary separation filter device is also not unique. For example, the second-stage filtering mechanism is the rotary separation filter device 12A of the structure shown in Figure 8 above, or it can also be a rotary separation filter device of other structures. The embodiments of the present disclosure do not limit this.

[0077] Of course, the first-stage filtering mechanism and the second-stage filtering mechanism can be two cascaded rotary separation filtering devices 12A.

[0078] Furthermore, since the waste filtered from the water flow settles at the bottom of the inertial separation filter mechanism and the rotary separation filter device, regular cleaning is required. In practice, to facilitate cleaning, hatches can be provided at the bottom of the inertial separation filter mechanism and the rotary separation filter device. For example, a removable hatch can be provided at the bottom of the outer cyclone space and the inner cyclone space of the rotary separation filter device to regularly clean the waste separated in the outer cyclone space and the inner cyclone space. This is not a limitation in the presently disclosed embodiments.

[0079] In some embodiments, the filter mechanism can adopt a conventional structure, that is, the filter mechanism has at least one water inlet, which is fluidically connected to the outlet of at least one water inlet channel of the cleaning device, and the filter mechanism includes a filter mechanism frame and a filter screen arranged on at least one surface of the frame, and the filter screen forms a water outlet of the filter mechanism; at least one filter screen cleaning mechanism can be arranged in the internal space of the filter mechanism, for example, it can be a brush structure that moves relative to the inner surface of at least one filter screen, and the brush structure can be driven by a first motor to rotate around the rotation axis of the brush to clean a certain portion of the inner surface of the filter screen, or a movement track of the brush structure can be arranged in the filter mechanism frame, and the brush structure can be driven by a second motor and a transmission mechanism to move along the movement track. Through the movement of the brush structure along the movement track, combined with the rotational movement of the brush structure, most of the inner surface of the filter screen of the filter mechanism can be cleaned. Through this arrangement, the problem of low cleaning efficiency caused by filter screen blockage during the cleaning process can be avoided.

[0080] In some embodiments, FIG12 provides a cross-sectional view of a fluid pumping mechanism and a portion of a water spraying mechanism. The fluid pumping mechanism 13 is used to generate a suction force, through which water is pumped from the water inlet to the water spraying mechanism 14 for discharge. The fluid pumping mechanism 13 includes a water pump motor 131, a water wheel 132, and a water outlet pipe 133. The water pump motor 131 is connected to the shaft of the water wheel 132, and the water outlet pipe 133 is disposed around the water wheel 132. The fluid pumping mechanism 13 generates a suction force by driving the water flow to rotate through the water pump motor 131 to draw water, and then guides the drawn water flow through the water outlet pipe 133 to be discharged from the water spraying mechanism 14.

[0081] The water spray mechanism 14 has the function of changing the direction of water spraying. Under the effect of the suction force generated by the fluid pumping mechanism 13, the water flow guided to the water spray mechanism 14 can be sprayed in the first direction, or in the second direction, or in other directions near the second direction.

[0082] In some embodiments, the water spray mechanism 14 includes: at least one water spray outlet and a water spray regulating mechanism; wherein, at least one water spray outlet is rotatably connected to the outlet of the fluid pumping mechanism, and the water spray regulating mechanism is transmission-connected to at least one water spray outlet to drive at least one water spray outlet to rotate between a first direction and a second direction; or at least one water spray outlet is divided into two groups, and the two groups of water spray outlets are fixedly connected to the outlet of the fluid pumping mechanism in an openable and closable manner, wherein one group of water spray outlets faces the first direction and the other group of water spray outlets faces the second direction, and the water spray regulating mechanism is synchronously transmission-connected to the two groups of water spray outlets to drive the two groups of water spray outlets to open selectively.

[0083] Specifically, the water spraying mechanism 14 can adjust the direction of water spraying by driving the water spraying port to rotate through the water spraying regulating mechanism, or can adjust the direction of water spraying by driving the water spraying ports with different water spraying directions to open and close through the water spraying regulating mechanism.

[0084] In one embodiment, as shown in Figure 13, in some embodiments, there are two water outlets 141, and the two water outlets 141 are respectively rotatably connected to the two outlets of the water outlet pipe 133. The water spray adjustment mechanism includes a direction adjustment motor 142 and a transmission assembly. The direction adjustment motor 142 is connected to the transmission assembly for transmission, and the transmission assembly is connected to the two water outlets 141. The direction adjustment motor 142 drives the two water outlets 141 to rotate to the first direction or the second direction by being connected to the transmission assembly for transmission, wherein the water spray adjustment mechanism can synchronously drive the two water outlets 141 to rotate, or asynchronously drive the two water outlets 141 to rotate.

[0085] Specifically, in FIG13 , there are two steering motors 142, and the transmission assembly includes two sets of gears, one set of gears corresponding to each water outlet 141 and each steering motor 142, and each set of gears includes two bevel gears, namely a first bevel gear 1431 and a second bevel gear 1432. The first bevel gear 1431 is connected to the axis of the steering motor 142, and the second bevel gear 1432 is axially sleeved on the water outlet 141. The first bevel gear 1431 and the second bevel gear 1432 are meshed with each other, so that when the steering motor 142 rotates, the first bevel gear 1431 and the second bevel gear 1432 rotate along with the steering motor 142, thereby driving the corresponding water outlet 141 to rotate, realizing independent steering drive of the two water outlets 141. In this embodiment, the two water outlets 141 are independently driven by the two steering motors 142 and the two sets of gears, so that the two water outlets 141 can rotate synchronously or asynchronously.

[0086] In some embodiments, as shown in FIG14 , the steering motor 142 has a single transmission assembly including a first worm 1441, a first worm gear, and a first connecting rod 1443. The first worm 1441 is connected to the shaft of the steering motor 142, and the first worm gear is axially sleeved in the middle of the first connecting rod 1443. The ends of the first connecting rod 1443 are fixedly connected to the two water spouts 141, respectively. The first worm 1441 meshes with the first worm gear. When the steering motor 142 rotates, the first worm 1441 rotates synchronously, which in turn drives the first worm 1441 to rotate the first worm gear. The first connecting rod 1443 rotates along with the first worm gear, thereby driving the two water spouts 141 to rotate. In this embodiment, the synchronous rotation of the two water spouts 141 is achieved through the transmission coordination between the single steering motor 142, the first worm 1441, the first worm gear, and the first connecting rod 1443.

[0087] In some embodiments, as shown in Figure 15, the steering motor 142 has one, and the transmission assembly includes a second worm 1451, a right bevel gear 1452, a left bevel gear 1453, a second connecting rod 1454 and a first connecting tube 1455; the second worm 1451 is connected to the shaft of the steering motor 142, and the second worm 1451, the right bevel gear 1452 and the left bevel gear 1453 are meshed and transmitted in sequence, one end of the second connecting rod 1454 is fixedly connected to the left bevel gear 1453, and the other end is fixedly connected to the middle position of the first connecting tube 1455, and the two ends of the first connecting tube 1455 are respectively fixedly connected to the two water outlets 141.

[0088] Then, when the direction adjustment motor 142 rotates, the second worm 1451 rotates synchronously, and the rotation of the second worm 1451 drives the right bevel gear 1452 to rotate, and the right bevel gear 1452 drives the left bevel gear 1453 to rotate. Since the second connecting rod 1454 is fixedly connected to the left bevel gear 1453, the rotation of the left bevel gear 1453 drives the second connecting rod 1454 to rotate, and the second connecting rod 1454 drives the first connecting pipe 1455 to rotate, so that the two water outlets 141 rotate synchronously with the first connecting pipe 1455, thereby achieving the effect of synchronous rotation of the two water outlets 141.

[0089] In some embodiments, as shown in Figure 16, there is at least one steering motor 142, there are two water outlets 141, the transmission assembly includes a third worm 146, two 147 gear sets and a clutch assembly 148, the third worm 146 is connected to the shaft of the steering motor 142, each 147 gear set corresponds to a water outlet 141, and each 147 gear set includes a cylindrical gear 1471, a third connecting rod 1472 and a second connecting tube 1473, one end of the third connecting rod 1472 is fixedly connected to the cylindrical gear 1471, and the other end is fixedly connected to one end of the second connecting tube 1473, the other end of the second connecting tube 1473 is fixedly connected to a water outlet 141, and the clutch assembly 148 is arranged between the two 147 gear sets and the third worm 146.

[0090] Figure 17 is a partial cross-sectional view of a clutch assembly 148 provided in an embodiment of the present disclosure. In combination with Figures 16 and 17, in some embodiments, the clutch assembly 148 includes a first gear 1481, a second gear 1482, an electromagnet 1483, an iron plate 1484 and an elastic member 1485. There are two first gears 1481, and the two first gears 1481 are arranged in a spaced relationship. The second gear 1482 is arranged between the two first gears 1481. The first gear 1481 is provided with a first gear tooth at one axial end facing the second gear 1482, and the second gear 1482 is provided with a second gear tooth at both axial ends, and the first gear tooth and the second gear tooth can mesh with each other. A third gear tooth is provided on the outer periphery of the first gear 1481. Gear 1481 is hollow and contains an electromagnet 1483, which is axially fixed to the device or water outlet pipe. An iron plate 1484 is fixedly connected to the first gear 1481 near the first gear tooth. A compressed elastic member 1485 is installed between the iron plate 1484 and the electromagnet 1483. A fourth gear tooth is provided on the outer periphery of the second gear 1482, which meshes with the third worm 146. When the electromagnet 1483 attracts the iron plate 1484, the third gear tooth on the first gear 1481 separates from the corresponding cylindrical gear 1471. When the electromagnet 1483 releases the iron plate 1484, the third gear tooth on the first gear 1481 meshes with the corresponding cylindrical gear 1471. The elastic member 1485 can be a spring.

[0091] Then, in this embodiment, the working principle of the transmission assembly is as follows: the rotation of the steering motor 142 drives the third worm 146 to rotate, and the rotation of the third worm 146 drives the first gear 1481 to rotate. When the electromagnet 1483 releases the iron plate 1484, the first gear 1481 is engaged with the second gear 1482, and the rotation of the first gear 1481 drives the second gear 1482 to rotate. The rotation of the second gear 1482 drives the cylindrical gear 1471 to rotate. Since the third connecting rod 1472 is fixedly connected to the cylindrical gear 1471, the third connecting rod 147 As the cylindrical gear 1471 rotates, the third connecting rod 1472 is connected to the second connecting tube 1473, so the second connecting tube 1473 rotates with the third connecting rod 1472. Finally, the second connecting tube 1473 drives the water outlet 141 to rotate, achieving the effect of a single direction adjustment motor 142 independently driving the rotation of each water outlet 141, so that the two water outlets 141 can rotate asynchronously. If the electromagnets 1483 in the two first gears 1481 both release the iron plates 1484, the direction adjustment motor 142 can drive the two water outlets 141 to rotate synchronously. In addition, when the electromagnets 1483 attract the iron plates 1484, the first gear 1481 and the second gear 1482 separate. At this time, the rotation of the direction adjustment motor 142 cannot be transmitted to the water outlet 141, thereby failing to drive the water outlet 141 to rotate.

[0092] In this embodiment, the clutch assembly 148 is used to achieve the effect that a single direction adjustment motor 142 supports the synchronous rotation and asynchronous rotation of the two water spraying ports 141 at the same time.

[0093] In some embodiments, as shown in Figure 18, another method of adjusting the water spray direction is provided. The four water spray outlets 141 are divided into two groups. The two groups of water spray outlets 141 are roughly symmetrically distributed on both sides of the equipment, and each includes a first water spray outlet roughly perpendicular to the direction of operation of the equipment and a second water spray outlet roughly parallel to the direction of operation of the equipment. A rotatable valve 1411 is provided in the flow channel of each water spray outlet 141; the water spray adjustment mechanism includes a direction adjustment motor 142 and a transmission assembly. The output of the direction adjustment motor 142 can drive the valve 1411 to rotate synchronously, thereby realizing the synchronous opening / closing of the first water spray outlet flow channel and the closing / opening of the second water spray outlet flow channel.

[0094] Of course, in actual applications, this embodiment can also be combined with the above-mentioned solution of rotating the water nozzles 141, so that the two groups of water nozzles 141 can also rotate near the first direction and the second direction. The embodiment of the present disclosure does not limit this.

[0095] As shown in Figures 1 and 19, a cleaning mechanism is provided in front of and / or behind the first water inlet along the direction of travel of the device. The cleaning mechanism includes at least one roller brush, which is driven by a walking mechanism on at least one side of the direction of travel of the device, or by at least one roller brush motor.

[0096] In one embodiment, in conjunction with Figure 1, a cleaning mechanism is provided in front of the first water inlet 111 along the direction of travel of the device, and the cleaning mechanism includes at least one roller brush 18. For example, a roller brush 18 is provided in front of the first water inlet 111 along the direction of travel of the device, and at least one axial end of the roller brush 18 is transmission-connected to the wheel of the walking mechanism. When the walking mechanism moves, the roller brush 18 is driven to rotate together, or the roller brush 18 can also be transmission-connected to a roller brush motor, and the roller brush 18 is driven by the roller brush motor to rotate; or, two roller brushes are provided in front of the first water inlet 111 along the direction of travel of the device, and the two roller brushes 18 are axially fixedly connected or movably connected, such as If the two roller brushes 18 are axially fixedly connected, similar to the case with a single roller brush 18, if the two roller brushes 18 are movably connected, the two roller brushes 18 are respectively connected to the travel mechanism on either side of the device. For example, if the travel mechanism is a wheeled travel mechanism or a tracked travel mechanism, the axial ends of the two roller brushes 18 facing the travel mechanism are connected to the travel wheels of the wheeled travel mechanism or the rolling wheels of the tracked travel mechanism. When the travel mechanism moves, the two roller brushes 18 rotate together. In particular, when the travel speeds of the travel mechanisms on both sides of the device are inconsistent, the two roller brushes 18 rotate at a differential speed, allowing the device to clean the surface to be cleaned during the turn. Optionally, the roller brush 18 rotates toward the first water inlet 111 to carry garbage stirred up by the roller brush 18 on the surface to be cleaned into the first water inlet 111. Of course, a cleaning mechanism including at least one roller brush 18 can also be provided behind the first water inlet 111 in the direction of travel of the device. The driving method of the roller brush 18 arranged behind the first water inlet 111 is the same as that of the roller brush 18 arranged in front of the first water inlet 111. The difference is that the rotation direction of the roller brush 18 arranged behind the first water inlet 111 is opposite to the rotation direction of the roller brush 18 arranged in front of the first water inlet 111.

[0097] In another embodiment, a cleaning mechanism may be provided in front of and behind the first water inlet 111 along the direction of travel of the device, each cleaning mechanism comprising at least one roller brush. Optionally, the cleaning mechanisms in front of and behind the first water inlet 111 may have the same number of roller brushes. The number, drive method, and rotation direction of the roller brushes in the cleaning mechanisms in front of and behind the first water inlet 111 are the same as those in the above embodiment and are not further described here.

[0098] For example, with reference to Figure 19 , in some embodiments, a first roller brush 181 and a second roller brush 182 are respectively provided in front of and behind the first water inlet 111 in the direction of travel of the device. The first roller brush 181 and the second roller brush 182 are arranged axially parallel to each other, and are driven by a traveling mechanism or a roller brush motor on both sides of the device, so that the two roller brushes rotate in opposite directions. Optionally, the first water inlet 111 is located on a bottom shell corresponding to the first roller brush 181 and the second roller brush 182, and bristles or scrapers are provided around the roller brushes. When the two roller brushes 18 rotate in opposite directions, the bristles or scrapers on the two roller brushes 18 may interfere with each other or not. If they interfere with each other, the bristles or scrapers of the first roller brush 181 and the second roller brush 182 will contact the bottom shell of the body around the first water inlet 111 to form a relatively closed suction space. Compared with general equipment, the suction force generated by the fluid pumping mechanism will produce a greater negative pressure in the suction space. On the one hand, the chassis of the body can be designed to be relatively higher to improve the obstacle crossing ability of the equipment; on the other hand, it is also easier to suck the garbage scrubbed by the roller brushes into the first water inlet 111, thereby improving the cleaning ability of the equipment.

[0099] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present disclosure should be included in the scope of protection of the present disclosure.
