The three embodiments all relate to a mechanical reversing wall-touching detection mechanism for a pool cleaning machine, which is installed on the cleaning machine to facilitate the cleaning machine to perform wall-touching detection and reversing. The mechanism has a rotatable pump casing, and the rotatable pump casing cooperates with the impeller of the suction component. The torque of the impeller is transmitted by utilizing the coupling principle, so that the rotatable pump casing and the impeller rotate in the same direction. The cleaning machine moves under the action of the reverse thrust of the water outlet of the rotatable pump casing. When touching the wall, the pump casing rotates and reverses under the action of the reversing component. The mechanism has a simple structure and flexible action, and can automatically traverse and clean the swimming pool, thereby improving work efficiency and reducing labor intensity.

[0059] Embodiment 1

[0060] The mechanical reversing wall-touching detection mechanism of the pool cleaning machine comprises a power unit non-rotatingly connected to the cleaning machine housing, a stop assembly 10 and a rotating reversing assembly, the rotating reversing assembly is rotationally connected to the cleaning machine housing 1 or the power unit, the stop assembly 10 is connected to the cleaning machine housing 1, the stop assembly 10 cooperates with the rotating reversing assembly, and the action of the power unit drives the rotating reversing assembly to act, providing power for the action of the rotating reversing assembly, realizing the same-direction rotation of the rotating reversing assembly and the suction assembly, realizing the cooperation of the rotating reversing assembly and the stop assembly 10, and through the cooperation of the stop assembly 10 with the rotating reversing assembly, the cleaning machine can perform wall-touching reversing when touching the wall. Through the action of the power unit, water is pumped up from the bottom, enters the interior of the cleaning machine housing 1 through the cleaning machine water inlet 21, is filtered by the filter device 19, and is discharged from the water outlet 2 of the rotary reversing component. The discharged water applies thrust to the cleaning machine to push the cleaning machine to move. When the cleaning machine moves, the rotary reversing component cooperates with the stop component 10, and the rotary reversing component and the cleaning machine housing remain in a relatively static state. The cleaning machine moves. When the cleaning machine touches the wall, the rotary reversing component disengages from the stop component 10 and performs a reversing action. The cleaning machine reverses and moves. The rotary reversing component cooperates with the stop component 10 again, and the above actions are repeated until the swimming pool is traversed and cleaned.

[0061] Specifically, Figure 1-8 As shown, the mechanical reversing wall-touching detection mechanism of the pool cleaning machine is installed on the cleaning machine body, including a power unit non-rotatably connected to the cleaning machine housing, the power unit provides power for the cleaning machine to suck sewage and move, the power unit can be fixedly connected to the cleaning machine housing, or softly connected, or other non-rotatable connection methods, selected according to actual needs, preferably, in this embodiment, the power unit is fixedly connected to the cleaning machine housing 1, the power unit includes a sealing device 15, a power drive device 13 and a suction component 3, the sealing device 15 is fixedly connected to the cleaning machine housing 1, the power drive device 13 is fixedly installed inside the sealing device 15, the suction component 3 is connected to the power drive device 13, the suction component 3 and the power drive device 13 are coaxially arranged, the power drive device 13 provides power for the suction component 3, so that the suction component 3 is in the power drive device 13 , the suction component 3 cooperates with the rotary reversing component, and the movement of the suction component 3 drives the rotary reversing component to move. The interaction and influence between the suction component 3 and the rotary reversing component are realized by coupling connection. In this embodiment, it is a hydraulic coupling connection. The change of the angular momentum generated by the interaction between the liquid and the suction component 3 and the rotary reversing component is used to transmit the torque of the suction component 3. When the suction component 3 rotates, the liquid is driven to flow, so that the rotary reversing component rotates in the same direction as the suction component 3 under the action of the torque transmitted by the liquid. The power driving device 13 provides power to the suction component 3, so that the suction component 3 is activated to suck the sewage, and the sewage is sucked into the cleaning machine housing 1. The sewage is filtered by the filtering device 19, and the filtered water is discharged through the water outlet 2 of the rotary reversing component to realize the movement of the cleaning machine.

[0062] The above-mentioned sealing device 15 is fixedly installed on the cleaning machine housing 1. The sealing device 15 can be fixedly installed inside the cleaning machine housing 1, or fixedly installed outside the cleaning machine housing 1, and fixedly connected to the outer wall of the cleaning machine housing 1, or the sealing device 15 is fixedly installed inside the cleaning machine housing 1, and the upper part of the sealing device 15 protrudes from the top of the cleaning machine housing 1, or other fixed installation methods are selected according to actual needs, and no specific requirements are made here. The setting of the sealing device 15 facilitates the installation of the power drive device 13. The power drive device 13 is sealed and installed in the sealing device 15 to prevent it from contacting with water and causing damage such as short circuit; or, the sealing device 15 may not be set, and the power drive device 13 is connected to the cleaning machine housing 1 through a flexible shaft or a hose, and is connected to the suction assembly 3. The power drive device 13 is located outside the cleaning machine, floating on the water surface or installed on the bank of the pool. It is selected according to actual needs, and no specific requirements are made here. Preferably, in this embodiment, the sealing device 15 is fixedly installed inside the cleaning machine housing 1.

[0063] The sealing device 15 is a sealed box structure with a storage compartment inside. The power drive device 13 is sealed and installed inside the sealing device 15 to prevent water from contacting the power drive device 13 and causing damage such as short circuit of the power drive device 13. The power drive device 13 is fixedly installed inside the sealing device 15 by connecting parts such as screws, and the drive shaft of the power drive device 13 extends out of the sealing device 15 and is connected to the suction assembly 3 to provide power for the action of the suction assembly 3. A seal is installed at the connection between the drive shaft of the power drive device 13 and the sealing device 15 to seal the extended drive shaft and prevent water from entering the sealing device 15 and causing damage to the power drive device 13. Preferably, here, the power drive device 13 is a motor, which is a commercially available product and is selected according to actual needs.

[0064] The suction assembly 3 is fixedly mounted on the free end of the driving shaft of the power drive device 13. The suction assembly 3 is used to suck the sewage after cleaning by the cleaning machine, so that it enters the interior of the cleaning machine and is filtered by the filter device 19. The suction assembly 3 is an impeller, preferably a centrifugal impeller, which is selected according to actual needs. The centrifugal impeller rotates under the drive of the power drive device 13, and the suction force generated sucks the sewage after cleaning by the cleaning machine into the interior of the cleaning machine housing 1, and is discharged from the water outlet 2 of the rotating reversing assembly after being filtered by the filter device 19. The rotation of the centrifugal impeller drives the rotation of the water entering the rotating reversing assembly, and water is used as the transmission medium of the torque of the suction assembly 3. The torque of the centrifugal impeller is transmitted by using the change of the kinetic moment generated by the interaction between water, the centrifugal impeller and the rotating reversing assembly, so that the rotating reversing assembly rotates in the same direction as the centrifugal impeller, thereby realizing the walking and reversing of the cleaning machine.

[0065] The above-mentioned rotating reversing component includes a rotating component and a reversing component. The rotating component is connected to the cleaning machine housing 1 or the power drive device 13 or the suction component 3, and the reversing component is connected to the rotating component. When the rotating component rotates and stops or the cleaning machine changes its state between movement and stillness, it drives the reversing component to rotate, so that the reversing component contacts and disengages from the stop component 10, thereby causing the cleaning machine to reverse.

[0066] Specifically, Figure 5As shown, the rotating assembly includes a rotating part and a rotating part 12, the rotating part and the rotating part 12 are fixedly connected, the rotating part is provided with a waterway 4 and a water outlet 2, after the water entering the rotating part enters the waterway 4, under the action of the coupling force transmitted by the suction component 3 and the water, the rotating part is driven to rotate. The rotating part is a shell structure with a space inside, and one end of the rotating part shell structure is open, which is convenient for the rotating part to match with the suction component 3 when installed, and the other end of the rotating part shell structure is provided with a water outlet 2, which is convenient for the filtered water to be discharged therefrom, and when discharged, a thrust is applied to the cleaning machine to drive the cleaning machine to move. The rotating part 12 is fixedly installed at the open end of the rotating part, and the rotating part 12 is adapted to the shape of the open end of the rotating part, and is fixedly installed along the circumference of the open end of the rotating part. The angle between the water outlet direction of the water outlet 2 and the horizontal plane is less than 90°, which is convenient for providing thrust to the cleaning machine.

[0067] like Figure 2-8 As shown, the rotating part includes an inner shell structure 5 having a waterway 4 and a water outlet 2, which cooperates with the suction component. The inner shell structure 5 is a volute structure, and the internal space of the volute structure is the waterway 4 where water flows. The suction component 3 is arranged in the waterway 4, and the shell of the inner shell structure 5 has a certain height, and the minimum value of the height is adapted to the height of the suction component 3, so that the suction component 3 is located inside the inner shell structure 5 after installation. Preferably, the shell height of the inner shell structure 5 is greater than the height of the suction component 3, so that the water flows in this waterway 4 and is discharged through the water outlet 2. When the centrifugal impeller of the suction component 3 rotates, it drives the water flow to rotate. When the water flows in the waterway 4, the torque of the suction component 3 is transmitted, which drives the inner shell structure 5 to rotate. The rotation of the inner shell structure 5 drives the direction of the water discharged from the water outlet 2 to change, thereby changing the walking direction of the cleaning machine. Preferably, the axis of the inner shell structure 5 coincides with the axis of the suction component 3, so that the inner shell structure 5 and the suction component 3 rotate around the same axis to reduce the power transmission loss.

[0068] A further optimized solution is that an outer shell structure 6 is fixedly installed on the outer side of the inner shell structure 5, and the outer shell structure 6 is arranged around the outer side of the inner shell structure 5. The inner shell structure 5 is located inside the outer shell structure 6, and the outer shell structure 6 is connected to the unopened end of the inner shell structure 5, and the end of the outer shell structure 6 is not open. The inner wall of the outer shell structure 6 and the outer wall of the inner shell structure 5 form a storage bin, and the outer shell structure 6 and the open end 50 of the inner shell structure are provided on the same side to form the open end 60 of the outer shell structure, that is, the end of the outer shell structure 6 is open to facilitate water entry. The inner shell structure 5 and the outer shell structure 6 can be integrally formed, or they can be connected by bolts and other connectors, or other fixed connection methods, which can be selected according to actual needs, and no specific requirements are made here. Preferably, here, the inner shell structure 5 and the outer shell structure 6 are integrally formed, and the structure is stable and not easy to deform or damage.

[0069] A plurality of resistance members 7 are arranged on the inner wall of the outer shell structure 6. When the cleaning machine is in use, water enters the inner shell structure 5 from the open end 60 of the outer shell structure under the action of the suction assembly 3, and under the rotation of the suction assembly 3, the torque is transmitted by utilizing the change of the momentum generated by the interaction of the suction assembly 3, water and the inner shell structure 5, so that the inner shell structure 5 rotates in the same direction, and the water is discharged from the water outlet 2 of the inner shell structure 5, so that the rotating part rotates under the action of the water channel 4 in the inner shell structure 5. At the same time, the space between the inner shell structure 5 and the outer shell structure 6 is filled with water, which provides resistance for the inner shell structure 5 when rotating, reduces the rotation speed of the inner shell structure 5, and further reduces the rotation speed of the rotating part. The setting of the resistance member 7 can strengthen the strength of the outer shell structure 6 and the inner shell structure 5, reduce their deformation, and at the same time play a role in increasing resistance, reducing the rotation speed of the inner shell structure 5, and facilitating the reversing of the reversing assembly. The resistance member 7 can be a blade, a reinforcing rib, or other structures. The resistance member 7 is preferably a blade. Whether the resistance member 7 is set or not and the number and size of the blades when the resistance member 7 is set are selected according to the required rotation speed of the rotating part.

[0070] Alternatively, the outer shell structure 6 is not provided outside the inner shell structure 5, and the resistance member 7 can be directly fixedly installed on the outer wall of the inner shell structure 5, which can also achieve the above-mentioned deceleration effect. Whether the outer shell structure 6 is provided or not is selected according to actual needs. In this embodiment, the provision of the outer shell structure 6 makes the structure of the rotating part beautiful, while protecting the inner shell structure 5 and reducing damage to the inner shell structure 5. At the same time, it avoids the resistance member 7 provided on the outer wall of the inner shell structure 5 from causing scratches to the user.

[0071] On the contrary, when the coupling force between the suction component 3 and the rotating component is insufficient, resulting in the rotating component rotating too slowly or even unable to rotate, the coupling force can be increased by cooperating with the suction component and / or the rotating component to achieve the ideal rotation speed of the rotating component. In addition, by providing a soft contact component with low friction or low thrust, such as soft hair, between the suction component 3 and the rotating component, the torque can also be increased to achieve the desired rotation speed of the rotating component.

[0072] like Fig.15 and 16 As shown, in order to increase the coupling force between the suction component 3 and the rotating component, a coupling surface 25 is provided on the inner wall of the rotating component. Specifically, a coupling surface 25 is provided on the inner wall of the connection between the water channel 5 of the inner shell structure 5 and the water outlet 2. The coupling surface 25 is a planar structure and is fixedly mounted on the inner wall of the rotating component. Preferably, the coupling surface 25 is integrally formed with the inner wall of the rotating component to increase the coupling force between the suction component 3 and the rotating component so that the rotation speed of the rotating component meets the requirements.

[0073] like Fig.17As shown, in order to increase the coupling force between the suction component 3 and the rotating component, a kinetic energy transfer component 26 is provided on the inner wall of the rotating component. Specifically, a plurality of kinetic energy transfer components 26 are fixedly installed on the inner wall of the inner shell structure 5. The kinetic energy transfer components 26 extend into the water channel to change the torque transmitted by water and increase the coupling force. The plurality of kinetic energy transfer components 26 can be installed on the inner wall of the inner shell structure 5 at equal intervals, or fixedly installed on the inner wall of the inner shell structure 5 at non-equal intervals, or other arrangements can be made according to actual needs. No specific requirements are made here. The fixed connection method between the kinetic energy transfer component 26 and the inner shell structure is preferably an integral molding. Here, the kinetic energy transfer component 26 is preferably a blade.

[0074] like Figure 18-20 As shown, a plurality of kinetic energy transmission components 26 can be fixedly mounted on the suction assembly 3, or a plurality of kinetic energy transmission components 26 can be fixedly mounted on the top inner wall of the inner shell structure 5, or a plurality of kinetic energy transmission components 26 can be fixedly mounted on both the suction assembly 3 and the top inner wall of the inner shell structure 5, and when the kinetic energy transmission components 26 are fixedly mounted on both at the same time, the kinetic energy transmission components 26 on the suction assembly 3 are located at the top of the suction assembly 3, and the kinetic energy transmission components 26 are mounted on the inner wall of the top of the inner shell structure 5 corresponding to the top of the suction assembly 3, so that the kinetic energy transmission components 26 on the suction assembly 3 and the kinetic energy transmission components 26 on the inner wall of the top of the inner shell structure 5 are arranged relative to each other, which is convenient for the transmission of the torque of the suction assembly 3 and increases the coupling force between the suction assembly 3 and the rotating assembly. The number of kinetic energy transmission components 26 is selected according to actual needs, and no specific requirements are made here. Here, the kinetic energy transmission components 26 are preferably blades.

[0075] When the rotating part is installed, the inner shell structure 5 is coaxially arranged with the suction assembly 3. In order to form the waterway 4 of the inner shell structure 5, a bottom plate 18 is installed at the open end 50 of the inner shell structure, that is, the open end 50 of the inner shell structure is not open, and the bottom plate 18 is installed. The bottom plate 18 is fixedly connected to the open end 50 of the inner shell structure. The shell of the inner shell structure 5 and the bottom plate 18 form the waterway 4 for water flow, which is convenient for the filtered water to flow and be discharged in the waterway 4. At the same time, a through hole 180 is provided on the bottom plate 18, which is convenient for the suction assembly 3 to be installed in the internal space of the inner shell structure 5. The center line of the through hole 180 coincides with the axis of the inner shell structure 5, and they are coaxially arranged. The axis of the inner shell structure 5 coincides with the axis of the suction assembly 3, so that the inner shell structure 5 can rotate under the rotation of the suction assembly 3 through the torque of the suction assembly 3 transmitted by water, thereby driving the rotating part to rotate, so that the inner shell structure 5 and the suction assembly 3 rotate in the same direction. The diameter of the through hole 180 on the bottom plate 18 is adapted to the size of the suction assembly 3, which is convenient for the installation of the suction assembly 3 and for the filtered water to enter the waterway 4 inside the inner shell structure 5 from the water inlet of the centrifugal impeller of the suction assembly 3 and through the centrifugal impeller. The bottom plate 18 can be fixedly connected to the inner shell structure 5 by connecting parts such as screws, or integrally formed, or plugged, or other fixed connection methods, which are selected according to actual needs and are not specifically required here. Here, the shape of the bottom plate 18 is adapted to the shape of the opening end 50 of the volute-shaped inner shell structure 5.

[0076] The rotating part 12 is fixedly mounted at the opening end 60 of the shell structure, or at the through hole 180 of the bottom plate 18, which is selected according to actual conditions. In this embodiment, the rotating part 12 is fixedly mounted at the opening end 60 of the shell structure. Figure 7 and 8As shown, the rotating part 12 includes at least one group of rolling elements 120, rolling supporting elements 121 and supporting elements 122. The rolling supporting elements 121 are fixedly connected to the edge of the opening end of the outer shell structure 6, and the supporting elements 122 are fixedly connected to the inner wall of the cleaning machine housing 1. Here, the rolling elements 120 are in two groups, and the rolling elements 120 are rollingly connected to the cleaning machine housing 1, the rolling supporting elements 121 and the supporting elements 122 respectively. A mounting groove 123 is provided on one side of the rolling supporting element 121. The shape of the mounting groove 123 is adapted to the shape of the rolling element 120 and is used to hold the rolling element. A groove 125 is provided on the other side of the rolling supporting element 121. The position of the groove 125 corresponds to the position of the mounting groove 124. A mounting groove 124 is provided on the inner wall of the cleaning machine housing 1. The shape of the mounting groove 124 is adapted to the shape of the rolling element 120 and is used to hold the rolling element 120. A groove 126 is provided on one side of the supporting element 122. Here, the rolling member 120 is a ball, which is installed in the mounting groove 123 of the rolling support member 121. At the same time, the ball is installed in the mounting groove 124 of the cleaning machine housing 1.

When the resistance plate 8 is in a vertical state, the lowest end of the stopper 11 is higher than the top end of the stopper assembly 10, and the stopper assembly 10 does not block the stopper 11. When the rotating assembly rotates, the resistance plate 8 tilts backward, the rotating shaft rotates, the lowest end of the stopper 11 is lower than the top end of the stopper assembly 10, the stopper 11 contacts the stopper assembly 10, and the stopper assembly 10 blocks the stopper 11, thereby realizing the stopping and movement of the rotating assembly, and then realizing the reversal of the cleaning machine.

The next reversing component is blocked by the stopper component 10, and the previous action is repeated to perform the reversal of the cleaning machine. The positions between two or more reversing components are determined according to the preset trajectory of the cleaning machine when it moves.

[0087] A filter device 19 is installed inside the cleaning machine housing 1 to filter sewage entering the cleaning machine housing 1 and intercept impurities and other dirt. The filter device 19 is preferably a filter net, and the filter net and the cleaning machine housing 1 form a space for storing impurities and other dirt. A water inlet 21 is provided at the bottom of the cleaning machine housing to facilitate the entry of sewage into the cleaning machine, and a water inlet cover 20 is installed at the water inlet 21. The water inlet cover 20 is rotatably connected to the inner wall of the cleaning machine housing 1, and the water inlet cover 20 can rotate relative to the water inlet 21, so that when water enters the water inlet 21, the water inlet cover 20 opens under the impact of the water flow, and sewage enters the cleaning machine housing 1, is filtered by the filter device 19, and the filtered water flows along the waterway 4 in the inner shell structure 5 and is discharged from the water outlet 2. When the power drive device 13 stops moving, the water inlet cover 20 returns to its original position under the action of elastic force or its own gravity, and impurities and other dirt are trapped in the space formed by the filter device 19 and the cleaning machine housing to prevent dirt from leaking out and causing secondary pollution of the swimming pool. The cleaning machine is provided with a power supply, which is electrically connected to the power drive device 13, and provides electric energy to the power drive device 13. The power supply may be a battery fixedly installed in the sealing device 15, or a power supply arranged outside the sealing device 15, and the external power supply is electrically connected to the power drive device 13 via a cable 16 to provide electric energy to the power drive device 13, or a control component is arranged inside the sealing device 15, and the control component is electrically connected to the power supply outside the cleaning machine via a cable, and the control component is electrically connected to the power drive device 13, and the power supply provides electric energy to the power drive device 13 via the cable and then via the control component. Since the sealing device 15 is fixedly connected to the cleaning machine housing 1, the change of the angular momentum generated by the interaction between water and the rotating component and the suction component 3 transmits the torque of the suction component 3, so that the rotating component and the suction component 3 rotate coaxially and in the same direction, while the sealing device 15 does not rotate, and the cable 16 will not be caused to rotate and entangle, so that the cleaning machine using the cable power supply method is flexible in movement and easy to use. Figure 1 As shown, in this embodiment, the power source installed in the sealing device is a battery, and the battery is electrically connected to the power drive device 13, and the battery provides electrical energy to the power drive device 13.

When the cleaning machine is not started, the resistance plate 8 of the reversing assembly is in a vertical state, and the cleaning machine is started, and the power drive device 13 is activated to drive the suction assembly 3 to rotate , driven by the torque transmitted when the filtered water in the waterway 4 in the inner shell structure 5 flows, the rotating assembly rotates, and the resistance plate 8 falls backward under the resistance of the water, so that the reversing assembly rotates. When the reversing assembly moves to the stop assembly 10, since the resistance plate 8 is in a tilted state, the stop part 11 of the reversing assembly contacts the stop assembly 10, the stop part 11 is blocked, and the reversing assembly is blocked by the stop assembly 10, the rotating assembly stops rotating, and the water discharged from the water outlet 2 drives the cleaning machine to move. Under the resistance of the water, the resistance plate 8 keeps tilting in the opposite direction of the movement, and the suction assembly 3 is in the power drive device The device 13 rotates under the action of the cleaning machine to suck the sewage generated by the cleaning machine when cleaning the swimming pool. The sewage enters the cleaning machine and is filtered by the filtering device. The filtering device filters the sewage. The filtered water enters the water channel 4 of the inner shell structure 5 through the water inlet of the suction component 3, and the filtered water flows under the rotation of the suction component 3 and is discharged from the water outlet 2 of the inner shell structure 5. The discharged water provides the cleaning machine with forward power, so that the cleaning machine can move. When the cleaning machine touches the wall of the swimming pool or encounters other obstacles, the cleaning machine stops moving, and the resistance of the water on the resistance plate 8 disappears. The resistance plate 8 is reset and restored to a vertical state. At this time, the stopper 11 of the reversing assembly is disengaged from the stopper assembly 10, and the stopper 11 of the reversing assembly passes over the stopper assembly 10. The rotating assembly rotates, and the resistance plate 8 is tilted under the action of the water resistance, and the direction of drainage at the water outlet 2 is changed, so that the cleaning machine changes its movement direction. When the reversing assembly moves to the next stopper assembly 10, it is blocked by the stopper assembly 10 here, and the rotating assembly no longer rotates. The resistance plate 8 remains tilted, and the cleaning machine moves along the preset trajectory. When the cleaning machine touches the wall again, the above actions are repeated until the swimming pool is traversed and the swimming pool cleaning is completed.

The first coupling member 27 is fixedly mounted on the suction assembly 3, the second coupling member 28 is fixedly mounted on the inner shell structure 5 of the rotating assembly, and the second coupling member 28 is fixedly mounted on the top inner wall of the inner shell structure 5. The first coupling member 27 is fixedly mounted on the top of the suction assembly 3. The first coupling member 27 and the second coupling member 28 are positioned correspondingly, and the first coupling member 27 and the second coupling member 28 are arranged oppositely, with a certain gap between them. The first coupling member 27 and the second coupling member 28 can both be magnets, or only one of them can be a magnet. Specifically, when the first coupling member 27 is a magnet, the second coupling member 28 can be a magnet, or a ferromagnetic material such as iron, nickel, cobalt, etc. that can be attracted by a magnet; similarly, when the second coupling member 28 is a magnet, the first coupling member 27 can be a magnet, or a ferromagnetic material such as iron, nickel, cobalt, etc. that can be attracted by a magnet. Here, preferably, the first coupling member 27 and the second coupling member 28 are both permanent magnets, which are commercially available products and are selected according to actual needs. In this embodiment, the first coupling member 27 is fixedly connected to the suction component 3, so that the first coupling member 27 rotates with the rotation of the suction component 3, and the second coupling member 28 is fixedly connected to the top inner wall of the inner shell structure 5. During the rotation of the suction component 3, the torque transmission between the suction component 3 and the rotating component is realized through the repulsive or attractive interaction between multiple permanent magnets, so that the rotating component and the suction component 3 rotate in the same direction. At the same time, the magnetic field strength of the magnet or the gap size between the magnets can be adjusted within a certain range to adjust the size of the interaction force, so as to achieve different torque transmission and speed transmission requirements.

[0103] The first coupling member 27 is preferably fixedly connected to the suction component 3 by encapsulating the first coupling member 27 on the top of the suction component 3 by injection molding, and the second coupling member 28 is preferably fixedly connected to the top inner wall of the inner shell structure 5 by encapsulating the second coupling member 28 on the top inner wall of the inner shell structure 5 by injection molding, and the first coupling member 27 and the second coupling member 28 are preferably arranged face to face, and the torque of the suction component 3 is transmitted by magnetic coupling.

[0104] The number of the first coupling member 27 is at least one, and the number of the second coupling member 28 is at least one. Preferably, the number of the first coupling member 27 and the second coupling member 28 are consistent and used in pairs. The number of the first coupling member 27 and the second coupling member 28 is selected according to actual needs and is not specifically required here.

[0105] The other structures are the same as those of the first and second embodiments and will not be described again here.

[0106] The working process of this embodiment is as follows: the mechanical reversing and wall-touching detection mechanism of the cleaning machine is fixedly installed on the cleaning machine housing 1, and the cleaning machine is placed in the swimming pool. When the cleaning machine is in a stationary state, the resistance plate 8 of the reversing component is in a vertical state, the cleaning machine is started, and the power driving device 13 is actuated to drive the suction component 3 to actuate, so as to suck the sewage into the cleaning machine housing 1, and the filtering device filters it. The filtered water enters the rotating part, and enters the waterway 4 inside the inner shell structure 5 through the water inlet of the suction component 3, and flows along the waterway 4 and is discharged through the water outlet 2. At the same time, when the suction component 3 rotates, it drives the first coupling member 27 to rotate. The magnetic field of the first coupling member 27 interacts with the magnetic field of the second coupling member 28 fixed on the rotating component, and drives the rotating component to rotate, so that the rotating component rotates relative to the cleaning machine housing 1 through the rotating part, and the filtered water is discharged from the water outlet 2 through the waterway 4; when the rotating component rotates, the resistance plate 8 tilts in the opposite direction of rotation, and the reversing component The stopper 11 contacts the stopper assembly 10 to block the reversing assembly, the rotating part no longer rotates, the resistance plate 8 remains in a tilted state under the action of the water resistance, and the cleaning machine moves under the thrust of the water discharge from the water outlet 2 to clean the swimming pool; when the cleaning machine touches the wall, the water resistance acting on the resistance plate 8 disappears, the resistance plate 8 is reset and restored to a vertical state, the stopper 11 of the reversing assembly disengages from the stopper assembly 10, the rotating part continues to rotate, the stopper 11 of the reversing assembly passes over the stopper assembly 10 and continues to rotate, the drainage direction of the water outlet 2 changes, and then the walking direction of the cleaning machine is changed, the cleaning machine performs reversal, when the rotating part rotates, the resistance plate 8 tilts under the action of the water resistance, when the reversing assembly rotates to the next stopper assembly 10, the stopper 11 of the reversing assembly contacts the stopper assembly 10, the rotating part stops rotating, the cleaning machine moves under the action of the drainage at the water outlet 2, and when the cleaning machine touches the wall again, the above-mentioned actions are repeated until the swimming pool is traversed and the swimming pool cleaning is completed.

[0107] The advantages and positive effects of the present invention are as follows: due to the adoption of the above technical scheme, the mechanical reversing wall-touching detection mechanism of the pool cleaning machine has a compact structure and low production cost, can detect the wall-touching of the cleaning machine and perform reversing, and has a rotating reversing component structure that rotates relative to the cleaning machine housing, so that the walking direction of the cleaning machine changes when it touches the wall, and the working efficiency is high; it has a sealing device, which is fixedly connected to the cleaning machine housing. When an external power supply is used, a power drive device installed in the sealing device is electrically connected to the external power supply through a connecting cable, and the cable will not rotate with the rotating reversing component, and the cable will not be entangled, so that the cleaning machine that is powered by the cable can automatically reverse, and the cable will not be entangled, so that the cleaning machine has high working efficiency and is easy to use; it has a rotating component and a reversing component, and the rotating component and the cleaning machine housing can rotate relative to each other to drive the reversing component to rotate, and the reversing component is connected to the The stop assembly cooperates with each other to control the rotation of the rotating assembly, thereby controlling the direction of the cleaning machine's movement. The cleaning machine performs reversal, and the setting of the rotating assembly makes it convenient for the cleaning machine to reversing by touching the wall, and it has a simple structure, stable operation, and high working efficiency. The rotating assembly is coupled to the suction assembly through a coupling member, and the principle of magnetic coupling is utilized, that is, the interaction between the magnetic fields of the magnets or the attraction between the magnets and the ferromagnetic materials is used to transfer the torque of the suction assembly, so that the rotating assembly and the suction assembly rotate in the same direction, thereby causing the cleaning machine to reverse direction. The structure is simple, the operation is stable, and the installation is convenient. The rotating assembly is hydraulically coupled to the suction assembly, and the torque of the suction assembly is transferred by the change of the angular momentum generated by the interaction between water, the rotating assembly, and the suction assembly. The rotating assembly and the suction assembly rotate coaxially, thereby causing the cleaning machine to reverse direction. The structure is simple, the operation is stable, and the installation is convenient.

All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
