Description

Swimming pool cleaning device and flow channel regulating mechanism Technical Field

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

[0002] A pool cleaning machine is a device used to automatically or semi-automatically clean the water and bottom of a pool. It aims to reduce the burden of pool maintenance, improve cleaning efficiency, and maintain water clarity. Different types of cleaning machines have different components, generally including: a body structure, which typically includes a housing, a base, and a buoy; a travel mechanism, which enables the machine to move through the water so that it can cover the entire surface of the pool; a water suction and filtration system, which is the core of the machine's water cleaning process. Water is pumped into the machine through the suction port using a water pump, and then the dirt is filtered out through the filtration system before the cleaned water is discharged back into the pool; a drive system, which enables the machine to move through the water and includes, but is not limited to, an electric motor, a compressor, or a water pressure system, depending on the type of cleaning machine; and an intelligent control system, which can adjust cleaning behavior through preset programs or sensors, making cleaning more intelligent and efficient.

[0003] While many types of pool cleaning machines exist, these typically only have a single water inlet and flow channel to direct water into the filtration system. There's no solution for using different inlets and flow channels to guide water into the filtration system at different cleaning locations. Therefore, optimizing the existing single flow channel structure and opening the appropriate flow channel based on the machine's cleaning position has been a major technical challenge encountered in pool cleaning technology research.

[0027] The present disclosure provides a schematic diagram of the structure of a swimming pool cleaning device, as shown in Figures 1 and 2. The swimming pool cleaning device 100 includes: a body 110, a walking mechanism 120 and a filtering mechanism 130. The body 110 is provided with at least two water inlets 111 and two flow channels 112 corresponding to the two water inlets 111. The two water inlets include a first water inlet 111a and a second water inlet 111b. The two flow channels 112 include a first flow channel 112a and a second flow channel 112b. The first water inlet 111a and the first flow channel 112a are connected to each other. One end of the cleaning device is fluidically connected, the second water inlet 111b is fluidly connected to one end of the second flow channel 112b, the other end of the first flow channel 112a and the other end of the second flow channel 112b merge and connect to the filtering mechanism 130; the body is also provided with a snorkeling mechanism 140 and a flow channel adjustment mechanism 150, the snorkeling mechanism 140 is used to adjust the working position of the cleaning device in the swimming pool, and the working position includes at least a first depth position and a second depth position; the flow channel adjustment mechanism 150 is used to selectively open or close the first flow channel 112a and the second flow channel 112b. When the device is operating, the filter mechanism 130 draws water from the water inlet 111 through the flow channel 112, where it enters the filter mechanism 130 for filtration and cleaning before being discharged. Specifically, when the pool cleaning device 100 is cleaning the pool bottom or wall, the filter mechanism 130 draws water along the first water inlet 111a, the first flow channel 112a, and the water path of the filter mechanism, filters and processes the water, and then discharges the water. When the pool cleaning device 100 is cleaning the water surface, the filter mechanism 130 draws water along the second water inlet 111b, the second flow channel 112b, and the water path of the filter mechanism, filters and processes the water, and then discharges the water. Optionally, as shown in FIG1 , the first water inlet 111a and the second water inlet 111b are located on different sides of the body. Specifically, the first water inlet 111a is at the bottom of the body, and the second water inlet 111b is on the side of the body.

[0028] The working principle of the above-mentioned swimming pool cleaning device 100 (hereinafter also referred to as the device) is as follows: when the swimming pool cleaning device 100 realizes the function of cleaning on the pool surface (pool bottom or pool wall) or the water surface through the walking mechanism 120 and the snorkeling mechanism 140, the two flow channels 112 are selectively opened to adapt to the cleaning of the swimming pool cleaning device 100 at different positions. Specifically, the snorkeling mechanism 140 can change the buoyancy of the swimming pool cleaning device 100, so that it can clean on the pool bottom or pool wall, or on the water surface. When on the pool bottom or pool wall, the walking mechanism 120 drives the device to move forward on the surface, and one of the water inlets 111 located at the bottom of the device is opened. The filter mechanism 130 generates a suction force to suck the dust-laden water flow near the bottom water inlet 111 into the corresponding flow channel 112 and enter the filter mechanism 130 to separate the dirt and then discharge it outward. The suction of the filter mechanism 130 can form a negative pressure between the bottom water inlet 111 and the surface to be cleaned. At the same time, the drain outlet of the body 110 also provides a reverse direction opposite to the drainage direction. The force provides downward pressure for the device, allowing it to move closely against the surface. When on the water surface, the walking mechanism 120 is separated from the pool bottom and wall, and the other water inlet 111 on the side of the body 110 is near the waterline. At this time, the filter mechanism 130 uses suction force to draw the water flow from the side water inlet 111 into the corresponding flow channel 112, and the water enters the filter mechanism 130 to separate the dirt and then discharge it outward. At this time, the drain outlet of the body 110 can have a horizontal weight to provide thrust for the device's surface operation, or the device can be provided with a driving component, such as paddles on the outside of the walking wheels. The rotation of the paddles on the walking wheels provides propulsion, allowing the device to move on the water surface. Therefore, when the swimming pool cleaning device 100 cleans at different locations (including the pool bottom, pool wall, and water surface), the flow channels 112 corresponding to the two water inlets 111 will selectively open to adapt to the cleaning of the device at different locations.

[0029] In the embodiment of the present disclosure, at least two water inlets 111 and two flow channels 112 corresponding to the two water inlets 111 are provided on the body 110. One of the water inlets 111 is fluidically connected to the filtering mechanism via one flow channel, and the other water inlet 111 is fluidically connected to the filtering mechanism via another flow channel. The filtering mechanism can adaptively open and close the two water inlets and the corresponding two flow channels through a flow channel adjustment mechanism on the body to extract water for filtering. When the swimming pool cleaning device 100 is cleaning on the bottom or wall of the pool via the walking mechanism 120 and the snorkeling mechanism 140, the flow channel adjustment mechanism opens one of the water inlets and its corresponding flow channel to draw water into the filtering mechanism for filtering. When the swimming pool cleaning device 100 is cleaning on the water surface via the walking mechanism 120 and the snorkeling mechanism 140, the flow channel adjustment mechanism opens the other water inlet and its corresponding flow channel to draw water into the filtering mechanism for filtering. In this way, the two flow channels 112 are selectively opened according to the position of the device to adapt to cleaning at different positions of the swimming pool cleaning device 100, thereby improving the flexibility and comprehensiveness of cleaning.

[0030] The body 110 primarily refers to the main structure of the pool cleaning device, including but not limited to the housing. The housing serves not only as a protective outer layer but also provides the structural framework for the body 110, supporting and securing key internal components. For example, the body 110 includes a bottom housing, which supports and secures some components of the travel mechanism 120.

[0031] The travel mechanism 120 is the system that enables the pool cleaning device 100 to move through the water. It typically utilizes wheels or tracks. For example, if the device utilizes tracks, the travel mechanism 120 may include a drive motor, drive wheels, and tracks. A track is provided on each side of the body 110. Each track cooperates with at least two drive wheels, namely, a front wheel and a rear wheel. The drive motor drives at least one of the drive wheels to rotate, thereby driving the tracks to move the device. Of course, in practice, the travel mechanism 120 is not limited to tracks and wheels; other travel mechanisms are also possible, and this is not a limitation in the presently disclosed embodiments.

[0032] The snorkeling mechanism 140 is a device within the pool cleaning device 100 that adjusts buoyancy to achieve buoyancy and submersion, ensuring the device can maintain its proper position in water at varying depths to perform cleaning tasks. It is understood that the specific implementation of the snorkeling mechanism 140 is not limited. For example, in one embodiment, the snorkeling mechanism 140 may be implemented using an adjustable liquid device that changes the buoyancy of the device by injecting or draining liquid from within the device. Alternatively, in another embodiment, the snorkeling mechanism 140 includes an air bag that changes the buoyancy of the device by inflating or releasing gas into the bag, including but not limited to controlling the inflation volume of the bag through a pump or valve to adjust the buoyancy. Of course, in practice, the snorkeling mechanism 140 may also be implemented using other structures, or even more complex structures, and is not limited to the above examples, and the present disclosure is not limited thereto.

[0033] The function of the filter mechanism 130 is to filter and remove impurities from the pool water to ensure clear and clean water. The specific embodiment of the filter mechanism 130 is not limited. For example, as shown in Figure 2, the filter mechanism 130 includes a separator and a fluid pumping device. The inlet of the separator is connected to two water inlets 111 (the first water inlet 111a and the second water inlet 111b in Figure 2) through two flow channels 112 (the first flow channel 112a and the second flow channel 112b in Figure 2). It is understood that the separator can have only one inlet or multiple inlets. When the separator has multiple inlets, the multiple inlets are separately connected to the multiple flow channels. The outlet of the separator is connected to the fluid pumping device, which can generate a suction force to draw water near the water inlet 111 through the flow channel 112 into the separator. The separator cleans and filters the water. Finally, under the action of the suction force, the cleaned water is discharged into the pool, thereby cleaning the pool water.

[0034] In the embodiment of the present disclosure, the fluid pumping device can be optionally a water pump. In addition, the separation device is the core part of the filter mechanism 130, which is used to capture impurities, dirt and particles in the water. Common separation devices include but are not limited to filter screens, roller brushes or filter bags. In practice, the separation device can absorb water flows from different positions through different water inlets 111 and flow channels 112 for filtration. Therefore, the water inlet 111 and flow channel 112 can also be regarded as components of the filter mechanism 130, or the filter mechanism 130 can also include other structures, which is not limited in the embodiment of the present disclosure.

[0035] The specific implementation of the flow channel regulating mechanism 150 is not unique, and several examples are given below for implementation reference.

[0036] In some embodiments, the flow channel regulating mechanism 150 includes: a driving device and at least one baffle, the at least one baffle is arranged near the two flow channels, the driving device is transmission-connected to the at least one baffle, and drives the at least one baffle to move between a first position and a second position to selectively open or close the first or second flow channel.

[0037] In one embodiment, the number of baffles 152 can be one or two. If there is only one baffle 152, the driving device drives the baffle 152 to move between a first position blocking the first flow channel 112a and a second position blocking the second flow channel 112b, so that the baffle 152 is always in a position blocking one flow channel while the other flow channel is unblocked, thereby achieving selective opening of the two flow channels.

[0038] For example, as shown in Figures 3A and 3B, there is one baffle 152, and the drive device includes a motor 151. The baffle 152 is connected to the output shaft of the motor 151 and rotates around the output shaft. When the baffle 152 rotates to the first position, the baffle 152 cuts off the first flow channel 112a, leaving the second flow channel 112b unobstructed. When the baffle 152 rotates to the second position, the baffle 152 cuts off the second flow channel 112b, leaving the first flow channel 112a unobstructed. In the embodiment of the present disclosure, the first position includes the position where the baffle cuts off the first flow channel 112a, and the second position includes the position where the baffle cuts off the second flow channel 112b. The motor 151 drives the baffle to rotate between the first position and the second position, so that one of the flow channels is always in a cut-off state, thereby achieving the effect of selectively opening the flow channels.

[0039] In some actual usage scenarios, with reference to FIG1, FIG2, FIG3A and FIG3B, the first water inlet 111a is provided at the bottom of the device body, and the second water inlet 111b is provided at the side of the device body. When the swimming pool cleaning device 100 cleans the pool bottom or the pool wall, the device controls the driving device to rotate the baffle to the second position, cutting off the second flow channel 112b, as shown in B in FIG3B, so that the first flow channel 112a downstream of the first water inlet 111a is opened, so that the dirt near the first water inlet 111a is sucked away along the first flow channel 112b by the water flow under the action of the suction force. 2a and enters the filtering mechanism 130, where the dirt is filtered out and clean water is discharged. When the swimming pool cleaning device 100 is cleaning the water surface, the driving device is controlled to rotate the baffle to the first position, blocking the first flow channel 112a, as shown by A in FIG. 3A , so that the second flow channel 112b downstream of the second water inlet 111b is opened, so that dirt near the second water inlet 111b can enter the filtering mechanism 130 along the second flow channel 112b under the action of the suction force along the water flow, and the dirt is filtered out and clean water is discharged.

[0040] The disclosed embodiment drives a baffle to rotate to selectively cut off one of the two flow channels, so that one of the flow channels remains unobstructed, allowing the equipment to open the corresponding flow channel to suck in water near the corresponding water inlet for cleaning when cleaning at different positions. This method of selectively opening the flow channel has a simple structure and low cost.

[0041] In one embodiment, there are two baffles 152, and a driving device drives the two baffles 152 to move between a first state of cutting off the first flow channel 112a and a second state of cutting off the second flow channel 112b, so that the two baffles 152 are always in a state of cutting off one flow channel and the other flow channel is in a state of being unobstructed, thereby realizing the selective opening of one of the two flow channels.

[0042] For example, as shown in Figures 4 and 5, there are two baffles 152, including a first baffle 152a and a second baffle 152b. The driving device includes at least one motor 151. The first baffle 152a is connected to the output shaft of one motor 151 and can rotate around the output shaft. The second baffle 152b is connected to the output shaft of one motor 151 through a first transmission mechanism 153 to reciprocate. Optionally, the motor driving the first baffle 152a and the motor driving the second baffle 152b are the same motor. Of course, in practice, they can also be driven by two motors separately. When the first baffle 152a rotates to the first position A, , the first baffle 152a cuts off the first flow channel 112a, and the second baffle 152b is in a position to open the second water inlet 111b corresponding to the second flow channel 112b, so as to open the second flow channel 112b; when the first baffle 152a rotates to the second position, the first baffle 152a cuts off the second flow channel 112b or only opens the first flow channel 112a, and the second baffle 152b is in a position to close the second water inlet 111b corresponding to the second flow channel 112b, and the first flow channel 112a is opened. In the embodiment of the present disclosure, the first position includes the position where the first baffle 152a cuts off the first flow channel 112a (such as position A in Figure 4), and the position where the second baffle 152b opens the second water inlet 111b (such as position C in Figure 4); and the second position includes the position where the first baffle 152a cuts off the second flow channel 112b (such as position B in Figure 5), and the position where the second baffle 152b covers the second water inlet 111b (such as position D in Figure 5).

[0043] In combination with the usage scenario, referring to FIG4 , when the swimming pool cleaning device 100 is cleaning the water surface, the device controls the motor 151 to drive the first baffle 152a to rotate to position A in FIG4 , and at the same time, the second baffle 152b moves to position C in FIG5 . At this time, the first flow channel 112a is cut off, the second water inlet 111b is opened, and the second flow channel 112b is in an unobstructed state, that is, one of the second flow channels 112b is opened, so that the water flow near the second water inlet 111b is sucked into the second flow channel 112b and enters the filtering mechanism 130 under the action of the suction force, and the dirt in the water flow is filtered by the filtering mechanism 130 and then discharged back into the pool water; referring to FIG. 5. When the swimming pool cleaning device 100 is cleaning the pool bottom or wall, the device controls the motor 151 to drive the first baffle 152a to rotate to position B in FIG. 5 , while the second baffle 152b moves to position D in FIG. 5 . At this point, the second water inlet 111b is blocked, the second flow channel 112b is blocked, and the first flow channel 112a is unblocked. Thus, the first flow channel 112a is selectively opened, and water flowing near the first water inlet 111a is drawn into the first flow channel 112a under the action of suction force and enters the filter mechanism 130. The filter mechanism 130 filters the dirt in the water and then discharges it back into the pool water, thereby achieving a clean pool. Referring to FIG. 2 , the suction force is generated by a fluid pumping device in the filter mechanism 130, which is a water pump, to pump water from the water inlet to the outlet of the filter mechanism 130.

[0044] The embodiment of the present disclosure utilizes the motor 151 to drive the first baffle 152a to rotate to selectively open a flow channel, and simultaneously drives the second baffle 152b to move back and forth in a straight line to cover or open the second water inlet 111b, so that the second flow channel 112b is cut off and the second water inlet 111b is also covered, thereby preventing foreign matter from entering the flow channel space from the second water inlet 111b to the cut-off position of the second flow channel 112b, thereby reducing the risk of the flow channel being blocked.

[0045] In the above-mentioned flow channel regulating mechanism, the specific implementation of the first transmission mechanism 153 is not unique.

[0046] For example, in some embodiments, the first transmission mechanism 153 includes: a synchronous transmission component 1531, a first gear component 1532 and a linear transmission component 1533. One end of the synchronous transmission component 1531 is connected to the motor 151, and the other end is connected to the first gear component 1532, so as to synchronously transmit the rotation of the motor 151 to the first gear component 1532. The linear transmission component 1533 is engaged with the first gear component 1532 and is used to convert the rotational motion of the first gear component 1532 into linear motion. The second baffle 152b is fixedly connected to the linear transmission component 1533. When the motor 151 rotates, the second baffle 152b moves back and forth in the direction of the linear motion.

[0047] 5 , in one embodiment, the synchronous transmission assembly 1531 includes two synchronous pulleys 1531a and a synchronous belt 1531b. The synchronous belt 1531b is sleeved onto the two synchronous pulleys 1531a to achieve an adaptive connection. One of the synchronous pulleys 1531a is axially connected to the output shaft of the motor 151 so as to rotate synchronously with the motor 151. Specifically, the synchronous pulley 1531a is a transmission member that is typically used in conjunction with the synchronous belt 1531b. The synchronous pulley 1531a is generally provided with special teeth and grooves that match the teeth and grooves on the synchronous belt 1531b to ensure that the two operate synchronously. In this embodiment, since the length of the synchronous belt 1531b is adjustable and can synchronously transmit the rotation of the motor 151, the appropriate length of the synchronous belt 1531b can be selected based on the spatial characteristics between the motor 151 and the baffle, thereby improving the flexibility of installing the first transmission mechanism 153 between the motor 151 and the baffle.

[0048] 5 , in one embodiment, the first gear assembly 1532 is a transmission assembly of at least one gear. For example, the first gear assembly 1532 includes a driving wheel 1532a and at least one driven wheel 1532b. The driving wheel 1532a and the at least one driven wheel 1532b are meshed and connected in sequence. The driving wheel 1532a is connected to the shaft of a synchronous pulley 1531a away from the motor 151 to rotate with the synchronous pulley 1531a. One of the driven wheels 1532b is meshed with the linear transmission assembly 1533 to convert the rotational motion of the gear into linear motion. Specifically, the number of driven wheels 1532b in FIG5 is one. Of course, in practice, two or more driven wheels 1532b can also be used to mesh and transmit with the driving wheel 1532a, or only one driving wheel 1532a can be used to respectively transmit to the synchronous transmission assembly 1531 and the linear transmission assembly 1533. The embodiment is not limited to the embodiment shown in FIG5 . In addition, the driving wheel 1532a and the driven wheel 1532b in Figure 5 are two gears of different sizes and gear ratios. It can be understood that the number and size of the gears can be adaptively selected according to the transmission speed ratio requirements of the actual application scenario and the size of the installation space, and the embodiments of the present disclosure do not limit this.

[0049] Continuing with Figure 5 , in one embodiment, the linear transmission assembly 1533 can be a rack fixedly connected to the second baffle 152b. In practice, the rack and second baffle 152b can be fixedly connected or integrally formed, equivalent to providing a rack structure on the second baffle 152b, but this is not a limitation in the present embodiment. The rack meshes with a gear in the first gear assembly 1532 to convert the gear's rotational motion into linear motion, enabling the second baffle 152b to reciprocate along a straight line to cover or open the second water inlet 111b.

[0050] It can be understood that the function of the first transmission mechanism 153 is to convert the rotational motion of the motor 151 into linear motion, so that the rotational power output by the motor 151 can drive the first baffle 152a to rotate between the first position and the second position to cut off the first flow channel 112a or the second flow channel 112b, and can also drive the second baffle 152b to move back and forth in a straight line to cover or open the second water inlet 111b, so as to achieve the effect of selectively opening one of the two flow channels and synchronously covering and opening the second water inlet 111b.

[0051] In some embodiments, as shown in FIG6 , the number of baffles is two, and the driving device includes a motor 151. The number of motors 151 can be selected as one, and of course, two can be selected in practice, which will not be described in detail here. A second transmission mechanism 154 is provided between the motor 151 and the two baffles. The second transmission mechanism 154 is respectively connected to the output shaft of the motor 151 and the two baffles. The two baffles include a third baffle 152c and a fourth baffle 152d. The motor 151 drives the third baffle 152c and the fourth baffle 152d to reciprocate between the first state and the second state, that is, the third baffle 152c and the fourth baffle 152d are respectively connected to the second transmission mechanism 154. The third baffle 152c and the fourth baffle 152d are connected to the output shaft of the motor 151 for synchronous movement, wherein the movement directions of the third baffle 152c and the fourth baffle 152d are approximately perpendicular to each other. When the third baffle 152c and the fourth baffle 152d move synchronously to the first state, the third baffle 152c opens the first flow channel 112a and the fourth baffle 152d blocks the second flow channel 112b, thereby opening the first flow channel 112a (as shown in the state of FIG6 ); when the third baffle 152c and the fourth baffle 152d move synchronously to the second state, the third baffle 152c blocks the first flow channel 112a and the fourth baffle 152d opens the second flow channel 112b, thereby opening the second flow channel 112b. Depending on the configuration of the two flow channels, the movement directions of the third baffle 152c and the fourth baffle 152d can be any non-perpendicular angle.

[0052] Specifically, in this embodiment, the first state is where the third baffle 152c opens the first flow channel 112a and the fourth baffle 152d blocks the second flow channel 112b; the second state is where the third baffle 152c blocks the first flow channel 112a and the fourth baffle 152d opens the second flow channel 112b. In other words, in the first state, the two baffles only open the first flow channel 112a, while in the second state, the two baffles only open the second flow channel 112b, thereby achieving selective opening of the two flow channels.

[0053] In the aforementioned embodiment in which the baffle is driven to rotate to block the flow channel and selectively open one, since only one end of the baffle has support during rotation, when the baffle is in the blocking position, the persistent impact of the water flow on the baffle surface may generate a rotational torque, causing the baffle to shift from its staged position, thereby affecting the flow blocking effect. In contrast, the disclosed embodiment drives the two baffles to move linearly in synchrony. When the baffle blocks the flow channel, if fluid impacts the baffle surface, generating a linear impact force, the force applied to the baffle is more uniform, making the baffle less likely to shift position, thereby improving the reliability of blocking the first flow channel 112a or the second flow channel 112b.

[0054] The second transmission mechanism 154 is used to convert the rotational motion of the motor 151 into linear motion in two directions at an angle to each other, which are shown in two approximately perpendicular directions in Figure 6, so as to drive the third baffle 152c and the fourth baffle 152d to move back and forth to selectively cut off the two flow channels and realize the selective opening of one of the two flow channels.

[0055] In practice, the specific implementation of the second transmission mechanism 154 is not unique, including but not limited to a gear transmission structure.

[0056] For example, in combination with Figures 6 and 7, in one embodiment, the motor 151 has two output shafts, the third baffle 152c is provided with a first rack 1521, and the fourth baffle 152d is provided with a second rack 1522; the second transmission mechanism 154 includes a second gear assembly 1541, and the second gear assembly 1541 includes a first gear 1541a and a second gear 1541b, and the first gear 1541a and the second gear 1541b are respectively axially connected to the two output shafts at both ends of the motor 151, wherein the first gear 1541a is engaged with the first rack 1521 on the third baffle 152c, and the second gear 1541b is engaged with the second rack 1522 on the fourth baffle 152d. When the motor 151 rotates, the third baffle 152c and the fourth baffle 152d perform linear motion synchronously, and the directions of the linear motion of the third baffle 152c and the fourth baffle 152d are approximately perpendicular to each other. The second gear assembly 1541 is a transmission combination of at least one gear. Optionally, in this embodiment, the second gear assembly 1541 includes a first gear 1541a and a second gear 1541b.

[0057] Specifically, in conjunction with Figure 6, when it is necessary to selectively open the first flow channel 112a, the motor 151 is controlled to rotate clockwise, and the first gear 1541a and the second gear 1541b at both ends of the motor 151 rotate synchronously, wherein the first gear 1541a is engaged with the first rack 1521 to drive the third baffle 152c to move rightward, and the second gear 1541b is engaged with the second rack 1522 to drive the fourth baffle 152d to move upward until the first state is reached, the third baffle 152c opens the first flow channel 112a, and the fourth baffle 152d cuts off the second flow channel 112b, thereby completing the first flow channel 112 a is opened; when it is necessary to selectively open the second flow channel 112b, the control motor 151 is rotated counterclockwise, and the first gear 1541a and the second gear 1541b at both ends of the motor 151 rotate synchronously, wherein the first gear 1541a is engaged with the first rack 1521 to drive the third baffle 152c to move to the left, and the second gear 1541b is engaged with the second rack 1522 to drive the fourth baffle 152d to move downward, until the second state, the third baffle 152c cuts off the first flow channel 112a, and the fourth baffle 152d opens the second flow channel 112b to complete the opening of the second flow channel 112b.

[0058] In some application scenarios of the swimming pool cleaning device 100, with reference to FIG2 , the first water inlet 111a is provided at the bottom of the device and is connected to the first flow channel 112a downstream, and the second water inlet 111b is provided on the side of the device body 110 and is connected to the second flow channel 112b downstream. When the device is cleaning the surface to be cleaned (including the pool bottom and the pool wall), the control motor 151 is rotated in a first direction, for example, clockwise, to drive the third baffle 152c and the fourth baffle 152d to move to the first state, so as to select one of them to open. The first flow channel 112a allows water to flow from the first water inlet 111a and the first flow channel 112a into the filter mechanism 130 for filtration and then discharge; when the equipment is cleaning the water surface, the motor 151 is controlled to rotate in a second direction, for example, counterclockwise, to drive the third baffle 152c and the fourth baffle 152d to move to the second state, so as to selectively open the second flow channel 112b, allowing water to flow from the second water inlet 111b and the second flow channel 112b into the filter mechanism 130 for filtration and then discharge, thereby achieving the effect of cleaning the swimming pool.

[0059] This embodiment uses two gears as the second transmission mechanism 154 to convert the rotational motion of the motor 151 into linear motion in two directions to drive the two baffles to reciprocate between the first position and the second position. This not only achieves the effect of selectively opening the two flow channels, but also the structure of this selective opening scheme is simple.

[0060] In another embodiment, as shown in Figures 8 and 9, the motor 151 has two output shafts, two rows of first racks 1521 are provided on the third baffle 152c, and the two rows of first racks 1521 are arranged in parallel and spaced apart on one side of the third baffle 152c, and a row of second racks 1522 is provided in the middle position of one side of the fourth baffle 152d; the second transmission mechanism 154 includes: a second gear assembly 1541 and a rotating shaft 1542, the second gear assembly 1541 includes a third gear 1541c, a fourth gear 1541d, a fifth gear 1541e and a sixth gear 1541e, the third gear 1541c, the fourth gear 1541d and the fifth gear 1541e. The first gear 1541c and the fourth gear 1541d are respectively connected to the ends and the middle of the rotating shaft 1542. The sixth gear 1541e is connected to the output shaft of the motor 151. The third gear 1541c and the fourth gear 1541d are respectively meshed with the first racks 1521 on both sides of the third baffle 152c. The fifth gear 1541e is respectively meshed with the second rack 1522 and the sixth gear 1541e on the fourth baffle 152d. When the motor 151 rotates, the third baffle 152c and the fourth baffle 152d perform linear motion synchronously, and the directions of linear motion of the third baffle 152c and the fourth baffle 152d are perpendicular to each other. The second gear assembly 1541 is a transmission assembly of at least one gear. Preferably, in this embodiment, the second gear assembly 1541 includes the third gear 1541c, the fourth gear 1541d, the fifth gear 1541e, and the sixth gear 1541e, for a total of four gears.

[0061] 8 , when it is necessary to selectively open the first flow channel 112a, the control motor 151 is rotated counterclockwise, and the sixth gear 1541e rotates in the same direction as the motor 151, thereby driving the third gear 1541c, the fourth gear 1541d and the fifth gear 1541e on the rotating shaft 1542 to rotate in opposite directions, wherein the third gear 1541c and the fourth gear 1541d are engaged with the first racks 1521 on both sides of the third baffle 152c to drive the third baffle 152c to translate to the right, and the fifth gear 1541e is engaged with the second rack 1522 on the fourth baffle 152d to drive the fourth baffle 152d to move upward until the first state, the third baffle 152c opens the first flow channel 112a, and the fourth baffle 152d cuts off the second flow channel 112b, so as to complete the first flow channel 112a. 2a is opened; when it is necessary to selectively open the second flow channel 112b, the control motor 151 is controlled to rotate clockwise, and the sixth gear 1541e rotates in the same direction as the motor 151, thereby driving the third gear 1541c, the fourth gear 1541d and the fifth gear 1541e on the rotating shaft 1542 to rotate in the opposite direction, wherein the third gear 1541c and the fourth gear 1541d are engaged with the first racks 1521 on both sides of the third baffle 152c to drive the third baffle 152c to move horizontally to the left, and the fifth gear 1541e is engaged with the second rack 1522 on the fourth baffle 152d to drive the fourth baffle 152d to move downward until the second state, the third baffle 152c cuts off the first flow channel 112a, and the fourth baffle 152d opens the second flow channel 112b to complete the opening of the second flow channel 112b.

[0062] The structure of the second transmission mechanism 154 in this embodiment is relatively complex. At the same time, the two rows of first racks 1521 on the third baffle 152c are arranged in parallel and spaced apart on both sides of the third baffle 152c, and the portion of the third baffle 152c between the two rows of first racks 1521 is a hollow structure. Compared with the structure with only one row of racks on the third baffle 152c, when the motor 151 drives the third baffle 152c to move, the two sides of the third baffle 152c are evenly stressed, so that the third baffle 152c can move back and forth more smoothly and securely.

[0063] In some application scenarios of the swimming pool cleaning device 100, with reference to FIG2 , the first water inlet 111a is provided at the bottom of the device and is connected to the first flow channel 112a downstream. The second water inlet 111b is provided on the side of the device body 110 and is connected to the second flow channel 112b downstream. When the device is cleaning the pool surface (including the pool bottom and the pool wall), the control motor 151 is rotated in a first direction, for example, counterclockwise, to drive the third baffle 152c and the fourth baffle 152d to move to the first state, so as to selectively open the first flow channel 112a, allowing water to flow from the first water inlet 111a and the first flow channel 112a into the filter mechanism 130 for filtration and discharge; when the device is cleaning the water surface, the control motor 151 is rotated in a second direction, for example, clockwise, to drive the third baffle 152c to move to the first state. The fourth baffle 152d moves to the second state to selectively open the second flow channel 112b, allowing water to flow from the second water inlet 111b and the second flow channel 112b into the filtering mechanism 130 for filtration and then discharged, thereby achieving the effect of cleaning the swimming pool.

[0064] In some embodiments, in conjunction with the above-described embodiment of selectively opening or closing at least two flow channels, when the cleaning device is submerged at a first depth via the snorkeling mechanism 140, the flow channel regulating mechanism controls the first flow channel to open and the second flow channel to close; when the cleaning device is submerged at a second depth via the snorkeling mechanism 140, the flow channel regulating mechanism controls the second flow channel to open and the first flow channel to close. Here, the first depth position can be selected as the position of the device at the bottom or wall of the pool, and the second depth position can be selected as the position of the device at the surface of the water.

[0065] It is understandable that in order to accurately obtain the depth position of the device in the water, water level sensors, attitude sensors and other sensor elements can be set on the body. These sensor elements collect signals and send them to the device processor. The device processor analyzes the collected signals to accurately identify the position of the device in the water. Since this specific implementation method of detecting the position of the device in the water by sensor elements is not unique, technical personnel in this field can refer to technical solutions in related fields, which will not be elaborated here.

[0066] 1-9 , the disclosed embodiment further provides a flow channel adjustment mechanism 150 for selectively opening at least two flow channels connected to the inlet of the filter mechanism 130 on the pool cleaning device 100. The flow channel adjustment mechanism 150 includes a drive device and at least one baffle. The drive device is in transmission connection with the at least one baffle and is capable of driving the at least one baffle to move between a first position and a second position to selectively open the at least two flow channels.

[0067] In the disclosed embodiment, the flow channel regulating mechanism 150 selectively opens one of the two flow channels downstream of the two water inlets on the device. When cleaning at different locations of the device, the corresponding flow channel can be opened to direct water from the water inlet through the flow channel into the filter mechanism 130 for filtration and cleaning before discharge. This adapts to cleaning at different locations of the pool cleaning device 100, thereby improving the flexibility and comprehensiveness of the device's cleaning.

[0068] The specific implementation of the flow channel regulating mechanism 150 may refer to the above-mentioned embodiment of the swimming pool cleaning device 100 , and will not be described again here to avoid repetition.

[0069] In some embodiments, in conjunction with Figures 10-12, a first door stop 155 that can be passively opened and closed is provided at the first suction port 111a or in the first flow channel 112a, and a second door stop 156 that can be driven is provided at the second suction port 112b or in the second flow channel 112b. The second door stop 156 can be driven by a motor. For example, in one embodiment, in conjunction with Figure 10, a motor M can be used to drive the second door stop 156 in a gear transmission manner. The gear transmission can be two parallel-axis gears, one of which is connected to the output shaft of the motor M and the other is connected to the rotating shaft of the second door stop 156. The two parallel-axis gears are meshed with each other for transmission. Optionally, the parallel-axis gears include but are not limited to cylindrical gears. When the cleaning device is cleaning the pool bottom or wall, the second gate stop 156 closes the second suction port 112b or closes the second flow channel 112b, and the first gate stop 155 can be opened under the action of the fluid pumping device. The dust-laden water flow near the first suction port 111a passes through the first suction port 111a and the first flow channel 112a, thereby entering the filter mechanism for filtration and then being discharged from the body; when the cleaning device is cleaning on the water surface, part of the second suction port 112b is below the water surface and part is above the water surface. The motor drives the second gate stop 156 to open, so that the garbage and water flow near the second suction port 112b enter the filter mechanism through the second suction port 112b and the second flow channel 112b. At this time, since the fluid pumping device will preferentially act on the second fluid channel with smaller resistance, the first gate stop 155 in the first flow channel 112a with larger resistance or at the first suction port 111a will be in a closed state. That is, due to the opening of the second flow channel 112b, the first gate stop 155 will be in a closed state, even if the fluid suction device is turned on. Through the above arrangement, the structure of the entire device can be simplified while achieving the effect of selectively opening either the first fluid channel or the second fluid channel.

[0070] The above are merely embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present disclosure should be included in the scope of protection of the present disclosure.
