DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to explain the technical contents, the objects, and the effects of the present application in detail, the embodiments will be described below with reference to the accompanying drawings.

Referring to FIGS. 1-20, embodiments of the present application provide a water surface cleaning robot that can be used to clean the water surface of a water body and the garbage near water surface positions.

With reference to FIGS. 1, 5, and 8, a water surface cleaning robot includes a main body 1, a garbage bin 2 and at least one driving mechanism 3, where a cavity 11 is provided in the main body 1, the garbage bin 2 is provided at the cavity 11, the driving mechanism 3 is provided on the main body 1 for driving the main body 1 to move on the water surface, and optionally, the driving mechanism 3 is provided at the rear of the main body 1.

The water surface cleaning robot further includes an upper cover 4, the upper cover 4 is slidably arranged on the top of the main body 1, and the upper cover 4 is slidable between a closed position and an open position. When the upper cover 4 is in the closed position, the upper cover 4 covers the cavity 11, and a user cannot extract the garbage bin 2 from the cavity 11, and when the upper cover 4 is in the open position, the user can extract the garbage bin 2 from the cavity 11.

The upper cover 4 is slidably connected to the main body 1, and the opening and closing of the cavity 11 is realized by the structure of sliding the upper cover 4. This not only facilitates taking out the garbage bin 2, but also has a small lever effect at the connection between the upper cover 4 and the main body 1, so that accidental damage cannot easily occur, which is beneficial to extending the service life of the water surface cleaning robot.

With reference to FIGS. 1 to 4, the upper cover 4 is provided with a first limiting structure 431, the main body 1 is provided with a second limiting structure 15 cooperating with the first limiting structure 431, the first limiting structure 431 is an insertion block, the second limiting structure 15 is an insertion hole, and the insertion block is arranged along the sliding direction of the upper cover 4; and optionally, the first limiting structure 431 is a plug hole, the second limiting structure 15 is a insertion block, and the insertion block is arranged along the sliding direction of the upper cover 4. The cooperation of the insertion block and the insertion slot can prevent the vertical shifting of the upper cover 4, so as to ensure the structural stability of the water surface cleaning robot.

Specifically, the second limiting structures 15 are respectively provided on two opposite side walls of the cavity 11, and at least two of the first limiting structures 431 are provided on the upper cover 4. One part of the first limiting structure 431 cooperates with the second limiting structure 15 on one side wall of the cavity 11, and the other part of the first limiting structure 431 cooperates with the second limiting structure 15 on the other side wall of the cavity 11. Preferably, a base body 43 is provided on the upper cover 4, and the front side and the rear side of the base body 43 are respectively provided with the first limiting structures 431. It is further preferable that a side wall of the cavity 11 has an avoidance slot 16 for avoiding the base body 43, so that the upper cover 4 can be opened and closed to a greater degree. Whether the upper cover 4 is in the closed position or the open position, the upper cover 4 can be limited, thereby more sufficiently preventing the position of the upper cover 4 from vertically shifting.

With reference to FIGS. 3 and 4, in the present embodiment, the upper cover 4 is provided with a guide rod 41, the main body 1 is provided with a guide sleeve 13, and the guide rod 41 cooperates with the guide sleeve 13 so that the upper cover 4 is slidably connected to the main body 1. Preferably, the main body 1 is provided with a slot position for accommodating the guide rod 41, the guide sleeve 13 is provided in the slot position, and the arrangement of the slot position can save space, so that the volume of the water surface cleaning robot can be made smaller, and at the same time, the slot position can play the role of protecting the guide rod 41 to a certain extent. In other embodiments, the main body 1 is provided with a guide rod 41 and the upper cover 4 is provided with a guide sleeve 13, the guide rod 41 cooperating with the guide sleeve 13 such that the upper cover 4 is slidably connected to the main body 1. The cooperation of the guide rod 41 and the guide sleeve 13 enables the upper cover 4 to exhibit a linear sliding between the closed position and the open position, which is more convenient and smoother for the user, so as to enhance the user's use experience.

It can be understood that, in one implementation mode, at least two sets of guide sleeves 13 are provided on the main body 1. The upper cover 4 is limited when the two ends of the guide rod 41 are respectively moved and clamped to the corresponding sets of guide sleeves, and other displacements of the upper cover 4 except for movement in the extension direction of the guide rods 41 are limited due to the cooperation of the guide sleeve 13 and the guide rod 41. Specifically, a groove for accommodating the guide rod 41 is provided in the upper cover 4, and the guide sleeve 13 protrudes from the main body 1.

As shown in FIG. 5, in particular, a controller is provided in the main body 1, the controller is electrically connected to the driving mechanism 3, and optionally, the driving mechanism 3 includes a driving motor and a propeller 31, the output end of the driving motor is connected to the propeller 31, and the controller is electrically connected to the driving motor.

As shown in FIG. 6, further, the propeller 31 includes a hub 311 and a blade 312 provided at an outer periphery of the hub 311, the blade 312 being a member by which the propeller 31 generates thrust. Preferably, the rear portion of the hub 311 of the propeller 31 is provided with a vortex absorbed fin 313, and the inclination direction of the vortex absorbed fin 313 is the same as the inclination direction of the blade 312, both being left-hand rotation or both being right-hand rotation. It is further preferred that the rotation angle of the vortex absorbed fin 313 is the same as or similar to the rotation angle of the blade 312; in the present embodiment, the number of the vortex absorbed fins 313 is the same as the number of the blades 312, and the vortex absorbed fins 313 and the blades 312 are arranged in parallel in a one-to-one correspondence; the shape of the vortex absorbed fin 313 is consistent with or similar to the shape of the blade 312; the inclination angles of the vortex absorbed fin 313 and the blade 312 are consistent or close; the axial distance between the vortex absorbed fin 313 and the blade 312 is ⅓ to 1 times of the radius of the vane of the vortex absorbed fin 313; and the area of the vortex absorbed fin 313 is ½ to ⅕ of the area of the blade 312, and in the present embodiment, the area of the vortex absorbed fin 313 is ¼ of the area of the blade 312.

A small vane (namely, a vortex absorbed fin 313) with a certain angle and shape is mounted at an appropriate position on the rear portion (namely, the hub cap) of the hub 311 of the propeller 31, the vortex absorbed fin 313 being able to straighten the wake flow of the propeller 31, so that the surface water flow flows out almost along the fin straight line and diverges towards the rear of the hub cap, thereby weakening the hub vortex cavitation; since the hub vortex cavitation is weakened, the pressure at the rear end of the hub 311 is also reduced, and the induced resistance caused by the hub vortex cavitation is also reduced, thereby improving the propulsion efficiency of the propeller 31; and in addition, the torsion generated by the leaflet of the vortex absorbed fin 313 reduces the torque of the propeller 31 and generates the thrust force, so that the thrust force of the propeller 31 increases. At the same time, the vortex absorbed fin 313 can also effectively reduce the noise of the propeller 31 and the vibration amplitude of the propeller 31, and improve the stability of the water surface cleaning robot when working. (According to the relevant experimental data, the water surface ship equipped with the vortex absorbed fin 313 can achieve about 2%-5% energy saving effect).

The number of the vortex absorbed fins 313 is the same as the number of blades 312 on the propeller 31, and the vortex absorbed fins 313 and the blades 312 are arranged in a one-to-one correspondence, that is to say, the axial positions of the vortex absorbed fins 313 and the blades 312 corresponding thereto are the same. The axial positions of the vortex absorbed fins 313 and the blades 312 corresponding thereto are the same, so that counter-rotating eddy currents can be formed. The counter-rotating eddy currents can induce Upwash of the airflow inside the vortex absorbed fin 313 according to Newton's third law (acting force and reactive force); and the airflow washed up inside the propeller 31 with the vortex absorbed fin 313 will exert a reactive force, i.e., a downward pressure and a resistance, on the vortex absorbed fin 313 (and the propeller 31). Such an arrangement can enable the water surface cleaning robot to float better on the surface of the water, and this downward pressure will also help to a certain extent when going up the bank and up the steps.

As shown in FIG. 7, in one implementation mode, the propeller 31 further includes a flow guiding cover 314 provided at the front of the propeller 31 with respect to the hub cap. It could be appreciated that the front and rear portions herein are relative to the direction of movement of the water surface cleaning robot as it advances. It needs to be noted that the flow guiding cover 314 and the hub cap are both streamlined structures, the surface curvature of which is further determined by the arrangement space and the size of the blade 312. The flow guiding cover 314 having a circular arc-shaped outer surface conforms to the hydrodynamic structure, so that when a swimming pool robot moves forward, the thrust-weight ratio of the propeller 31 can be increased to achieve the effect of energy saving. Using only one support frame to support the propeller 31 not only can effectively reduce the hair filament winding on the support frame, but also can ensure the water discharge of the propeller 31 and reduce the kinetic energy waste.

The driving mechanism 3 further includes a fixing frame 32 for fixing the propeller 31, and the fixing frame 32 includes a support frame having a plurality of support ribs 321 for supporting the propeller 31.

As shown in FIGS. 5 and 7, in the present embodiment, the number of the driving mechanisms 3 is two, and the two driving mechanisms 3 are spaced apart. When the two driving mechanisms 3 are operated simultaneously, the machine advances. When one of the driving mechanisms 3 is operating or the rotational speeds of the two propellers 31 are not synchronized, steering of the machine can be achieved.

In some embodiments, the controller may be directly connected to a mains supply or mobile power supply device via a cable. In order to allow the water surface cleaning robot to move more flexibly, in connection with FIG. 1, in one embodiment, the main body 1 is provided with a rechargeable battery 12 electrically connected to the controller, i.e., the electric energy of the driving mechanism 3 is provided by the rechargeable battery 12.

With reference to FIGS. 1, 5, 8, and 9, the garbage bin 2 is provided with an inlet 21. Through the inlet 21, the garbage can enter the interior of the garbage bin 2 with the flow of water and then it is retained in the garbage bin 2. The inlet 21 is provided on a side wall of the garbage bin 2 close to the front of the main body 1. The garbage bin 2 includes a reset piece, a frame body 22 and a handle 23, the handle 23 is rotatably connected to the frame body 22, the reset piece respectively contacts the frame body 22 and the handle 23, and the reset piece is used for moving the handle 23 from a first position to a second position. The second position refers to the standing state or nearly standing state of the handle 23 with respect to the frame body 22 so as to maintain a certain distance between a hand-held position of the handle 23 and the frame body 22, thereby allowing a user to hand-hold the handle 23, and thus reducing the likelihood that the user's hands will touch the garbage. The reset piece includes, but is not limited to, a torsion spring, a spring plate, and the like. In the present embodiment, the reset piece 8 is a torsion spring, and specifically, a shaft portion 231 is provided on the handle 23, the handle 23 is rotatably connected to the frame body 22 via the shaft portion 231, and the torsion spring is sheathed on the shaft portion 231 so as to limit the torsion spring.

Referring to FIGS. 1 and 8, during the sliding of the upper cover 4 from the open position to the closed position, the upper cover 4 contacts the handle 23 of the garbage bin 2 located in the cavity 11 and gradually puts the handle 23 down. As shown in FIGS. 8 and 9, in order to allow a user to extract the garbage bin 2 while the frame body 22 is in a force-balanced state, the connection of the handle 23 and the frame body 22 is located at a central region of the top of the frame body 22. Preferably, one side of the top of the frame body 22 is provided with a receiving slot 221 for receiving at least a portion of the area of the handle 23, and the handle 23 can be at least partially received in the receiving slot 221 after being put down.

Optionally, the frame body 22 includes a body 222 and a turning plate 223, the handle 23 is rotatably connected to the body 222, the body 222 has an opening, the turning plate 223 is located at the opening, the turning plate 223 is used for opening and closing an inner space of the body 222, one end of the turning plate 223 is rotatably connected to the body 222, the other end of the turning plate 223 is provided with a first detachable connection structure 2231, the body 222 is provided with a second detachable connection structure cooperating with the first detachable connection structure 2231, and the inlet 21 is located on a first side wall of the body 222. The first detachable connection structure 2231 and the second detachable connection structure may be in the form of a snap, a magnetic attracting piece or other structures, such as a latch structure or the like. Preferably, the body 222 is integrally formed in a polygonal frame shape so that the frame body 22 can be completely opened when the turning plate 223 is opened, and the garbage in the frame body 22 can be more smoothly dropped.

Preferably, the opening of the body 222 is located at the bottom of the body 222, so that the user can avoid mis-touching garbage and enhance the user's use experience. The second detachable connection structure is located on a second side wall of the body 222, the first side wall being located opposite the second side wall, and the second side wall having sufficient space to provide the second detachable connection structure. In other embodiments, it is also possible that the opening is located on a side wall of the body 222, in which case the turning plate 223 may be considered as a side wall of the body, i.e., the filter basket is of a side-opening structure.

In some embodiments, one connection of the handle 23 to the body 222 is on the first side wall and the other connection is on the second side wall; in this embodiment, one connection between the handle 23 and the body 222 is located on a third side wall of the body, the other connection is located on a fourth side wall of the body, the fourth side wall is opposite to the third side wall, the first side wall is connected to the third side wall and the fourth side wall, respectively, and the second side wall is connected to the third side wall and the fourth side wall, respectively.

Referring to FIGS. 1, 5, 9, and 10, optionally, the water surface cleaning robot further includes a rolling member 5 provided on the main body 1 close to the inlet 21 of the garbage bin 2 for feeding garbage in water into the garbage bin 2. It could be appreciated that, as shown in FIG. 11, in some particular products, the rolling member 5 may be provided on the garbage bin 2 near the inlet 21 of the garbage bin 2.

The inlet 21 faces the movement direction of the water surface cleaning robot, and in the present implementation mode, the inlet 21 and the driving mechanism 3 are provided at two opposite ends of the main body 1. Specifically, the inlet 21 is provided at the front of the garbage bin 2, and the driving mechanism 3 is provided at the rear portion of the main body 1. It needs to be added that inlets 21 may be provided at two opposite ends of the garbage bin, respectively, so that when the driving mechanism 3 is takes a step back to move in another direction, the garbage may still enter the interior of the garbage bin 2 as water flows through the inlet 21, thereby enabling the water surface cleaning robot to collect floats both during forward and backward movement.

As shown in FIG. 10, in order to improve the cleaning effect of the water surface cleaning robot, it is preferable that a power assembly 8 for driving the rolling member 5 to rotate is provided in the main body 1, the power assembly 8 includes a rotating motor 81 or the like, the power assembly 8 is electrically connected to the controller, and the rechargeable battery 12 supplies electric energy to the power assembly 8. It needs to be noted that when the rolling member 5 is rotatably provided on the garbage bin 2 via a shaft member, a transmission wheel 82 is provided at the end of the shaft member, and the transmission wheel 82 is located on the outer side of the garbage bin 2. At this time, the power assembly 8 in the main body 1 drives the rolling member 5 to rotate via the transmission wheel 82, and the transmission wheel 82 includes but is not limited to a transmission gear, a contact runner, etc.

As shown in FIGS. 10 and 11, in order to further prevent the garbage in the garbage bin from overflowing, the garbage bin 2 is optionally further provided with a leakage prevention baffle 24, which closes at least part of the area of the inlet 21 when the leakage prevention baffle 24 is in a predetermined position.

In an embodiment, one side of the leakage prevention baffle 24 is hinged at the inlet 21 by means of a shaft rod 25. The shaft rod 25 can be driven so that the leakage prevention baffle 24 is driven to rotate about the axis of the shaft rod 25 to shield the inlet 21, with the effect that the garbage in the garbage bin 2 is prevented from overflowing from the inlet 21.

In a water surface cleaning robot with a leakage prevention baffle 24, the leakage prevention baffle 24 is opened during the process of collecting floats, so that the floats enter the garbage bin 2 under the action of the rolling member 5, and at this time it is difficult for the floats to overflow from the inlet 21 under the action of the water flow; and when the collection is stopped, the leakage prevention baffle 24 is used to shield the inlet 21 so as to avoid the overflow of the floats, so that the design size of the inlet 21 can be expanded as far as possible, and the re-overflow of the floats can be avoided while ensuring the collection efficiency.

As shown in FIG. 10, it can be understood that in a specific product, the leakage prevention baffle 24 and the rolling member 5 can be driven either by the same power assembly 8 or by different power driving mechanisms; for the sake of simplifying the structure, it is preferred that the leakage prevention baffle 24 and the rolling member 5 are driven by the same power assembly 8, that is, the leakage prevention baffle 24 is drivingly connected to the rolling member 5; and in particular, the power assembly 8 further includes a transmission assembly in transmission connection with the rotating motor 81, and the transmission assembly is respectively in transmission connection with the rolling member 5 and the shaft rod 25. As a further improvement, the transmission assembly only drives the rotation of the leakage prevention baffle 24 in a direction shielding the inlet 21, and makes the rotation direction of the rolling member 5 the same as the rotation direction of the leakage prevention baffle 24.

A limiting portion 242 is further included. Specifically, the limiting portion 242 can be provided on the main body 1 and can also be provided on the garbage bin 2. When the leakage prevention baffle 24 opens under the action of gravity, the leakage prevention baffle 24 abuts against the limiting portion 242, and assumes a state where the end of the leakage prevention baffle 24 away from the inlet 21 is inclined downwards, and when the leakage prevention baffle 24 abuts against the limiting portion 242, the included angle between the leakage prevention baffle 24 and the horizontal plane is 15°-40°. On the one hand, it can reduce the resistance in the process of the water surface cleaning robot moving, and on the other hand, it can guide the floats and improve the collection efficiency.

The practical process is: placing the water surface cleaning robot on the water surface, and using the driving mechanism 3 to drive the robot to move in a first direction; at this moment, the rotating motor 81 rotating forward, so that the rolling member 5 rotates in the direction of water flow, namely, rotating counterclockwise, and at this moment, the one-way bearing 85 being in a slip state, the leakage prevention baffle 24 opening under the action of gravity, and the rolling member 5 rotating counterclockwise to put the garbage into the garbage bin; and when the collection is stopped, the rotating motor 81 being takes a step back, causing the rolling member 5 to rotate clockwise, at which time the one-way bearing 85 is in transmission state so as to drive the leakage prevention baffle 24 to rotate so as to shield the inlet 21.

As shown in FIG. 11, in another implementation mode, the leakage prevention baffle 24 may also be arranged in the garbage bin 2 near the inlet 21, the leakage prevention baffle 24 being freely rotatable in the garbage bin 2, which may achieve a rotation of 0-100 degrees of the leakage prevention baffle 24 with the direction of the water flow (opposite to the direction of advance of the water surface cleaning robot). When the leakage prevention baffle 24 makes an included angle of 80-100 degrees with the direction of water flow, the leakage prevention baffle 24 is higher than the water line 9.

In one implementation mode, the leakage prevention baffle 24 is positioned such that the free end of the leakage prevention baffle 24 is 5-20 mm higher than the water line 9 when the leakage prevention baffle 24 is at an included angle of 90 degrees to the direction of water flow, and the free end of the leakage prevention baffle 24 does not just touch the brush vane of the rolling member 5 when it is closest to the brush vane of the rolling member 5 during the rotation of the leakage prevention baffle 24.

In order to simplify the structure of the garbage bin 2, when the water surface cleaning robot stops advancing and floats on the water surface, the leakage prevention baffle 24 is reset to the closed position due to its own buoyancy. In an alternative implementation mode, at least a portion of the area of the leakage prevention baffle 24 has a material density smaller than the density of water, water having a density of 1 g/cm3. When the water surface cleaning robot walks forward, the water flow will push the leakage prevention baffle 24 to rotate, so that the leakage prevention baffle 24 inclines backward by a certain angle, which is equivalent to opening the inlet 21, and the garbage can enter smoothly. When the water surface cleaning robot is stationary or take a step backs, the leakage prevention baffle 24 is reset to the closed position by buoyancy or water flow, and at this moment, the top end (i.e., free end) of the leakage prevention baffle 24 protrudes from the water line 9, thereby preventing the garbage from leaking out of the garbage bin 2.

In order to allow the leakage prevention baffle 24 to reset to the closed position more quickly, the leakage prevention baffle 24 is optionally provided with an air chamber, it being understood that the material density of the leakage prevention baffle 24 need not be smaller than the density of water. In other embodiments, to allow the leakage prevention baffle 24 to more quickly reset to the closed position, the leakage prevention baffle 24 is provided with a counterweight, which is located below the central axis of rotation of the leakage prevention baffle 24 when the leakage prevention baffle 24 is in the closed position, either as an additional weight or as a local area of the leakage prevention baffle 24 with the material density greater than the density of water. In summary, the leakage prevention baffle 24 include a movable structure including at least one of the above, such that the leakage prevention baffle 24 can be in a predetermined position.

In one implementation mode, as shown in FIG. 11, the limiting portion 242 is a limiting protrusion provided on the frame body 22. The rotation angle range of the leakage prevention baffle 24 is defined by the limiting portion 242. The rotation angle range of the leakage prevention baffle 24 is 0°-100°. The rotation angle of the leakage prevention baffle 24 is 0° when the leakage prevention baffle 24 is in a horizontal state, and the rotation angle of the leakage prevention baffle 24 is 90° when the leakage prevention baffle 24 is in a standing state. In the present embodiment, when the leakage prevention baffle 24 is at 80°-100°, the top ends of the leakage prevention baffle 24 all protrude from the water line 9. That is, in an actual product, the closed position of the leakage prevention baffle 24 may not correspond to a definite, single rotation angle value, but to one set of rotation angle range, such as 80°-100°.

With reference to FIGS. 1 to 4, 8, 11, and 12, optionally, the water surface cleaning robot further includes a solar panel 6, where the solar panel 6 is provided on the surface of the upper cover 4, a solar controller is provided in the main body 1, and the solar controller connects the rechargeable battery 12 and the solar panel 6. As a preferred implementation mode, the upper cover 4 is further provided with a first conducting structure 42 electrically connected to the solar panel 6; the main body 1 is provided thereon with a second conducting structure 14 electrically connected to the rechargeable battery 12; when the upper cover 4 is in the closed position, the first conducting structure 42 and the second conducting structure 14 are in electrical conduction; when the upper cover 4 is in the open position, the first conducting structure 42 and the second conducting structure 14 are electrically kept in conduction or disconnected in conduction; and the first conducting structure 42 is a metal contact plate, a metal spring plate, a metal probe, or a first plug and unplug connector.

In detail, when the upper cover 4 is in the open position, and it is desired that the first conducting structure 42 and the second conducting structure 14 continue to be conductive, a simple method is to provide the first conducting structure 42 as a metal contact plate having a long length in a length direction consistent with the sliding direction of the upper cover 4.

In other implementation modes, the first conducting structure 42 and the second conducting structure 14 may also be selected as existing non-metallic electrically conducting structures, such as magnetically attracted structures and like electrically conducting structures, so that the problem of corrosion of the metallic conducting structures is avoided, so as to extend the service life of the first conducting structure 42 and the second conducting structure 14 and enhance the user's experience.

With reference to FIGS. 11 and 12, in one implementation mode, the first conducting structure 42 is a wireless charging emission module, and the second conducting structure 14 is a wireless charging receiving module; specifically, a sealed bin 20 is provided in the main body 1, the wireless charging receiving module is provided in the sealed bin 20, and optionally, the rechargeable battery 12 is also located in the sealed bin 20; and a circuit board is provided in the sealed bin 20, and the wireless charging receiving module and the rechargeable battery 12 are respectively electrically connected to the circuit board.

When manufacturing, after the connection between the wireless charging emission module and the solar panel 6 is completed, the gap is sealed with glue, i.e., the wireless charging emission module is sealed, so that the wireless charging emission module is not affected by moisture; and since the wireless charging emission module is integrated with the solar panel 6 along with the upper cover 4, the wireless charging emission module is stationary with respect to the solar panel 6 no matter how to open or close the upper cover 4. A wireless charging receiving module is mounted in the sealed bin 20, the sealed bin 20 is waterproof, and it works as long as the wireless charging receiving module is mounted; when the upper cover 4 is closed, the positions of the wireless charging emission module and the wireless charging receiving module are corresponding, and wireless charging can be performed; and when the upper cover 4 is opened, the positions of the wireless charging emission module and the wireless charging receiving module are staggered, and then charging is stopped.

Optionally, the sealed bin 20 has a convex hull 201 protruding towards the upper cover 4, the wireless charging receiving module is at least partially located in the convex hull 201, and the arrangement of the convex hull 201 can not only facilitate the positioning and mounting of the wireless charging receiving module, but also reduce the distance between the wireless charging emission module in a corresponding position and the wireless charging receiving module, thereby improving charging efficiency.

The electric energy produced by the solar panel 6 can be used by the driving mechanism 3, which is beneficial for reducing the energy consumption of the water surface cleaning robot and reducing the use cost of the user. At the same time, the solar panel 6 and the driving mechanism 3 are electrically connected using a non-cable connection path, which can not only improve the aesthetics of the water surface cleaning robot, but also reduce the risk of accidental disconnection of the connection path between the solar panel 6 and the driving mechanism 3, so as to improve the service life of the water surface cleaning robot.

Optionally, the top surface of the upper cover 4 is provided with a mounting slot in which the solar panel 6 is mounted. Preferably, the solar panel 6 is inclinedly mounted in the mounting slot so that the liquid remaining on the solar panel 6 can be smoothly drained so as not to affect the operation of the solar panel 6. It can be easily understood that the solar panel 6 is inclinedly mounted so that an acute angle is formed between its top surface and the horizontal plane and the liquid attached to the solar panel 6 can be smoothly drained.

In another implementation, as shown in FIGS. 13 and 14, the electric energy generated by the solar panel 6 is transferred to an electric component, such as the rechargeable battery 12, in the main body 1 through a cable 45. Specifically, a chamber body 44 for accommodating the cable 45 is provided in the upper cover 4, and when the upper cover 4 is in an open position, the cable 45 is in an extended state in the chamber body 44, and when the upper cover 4 is in a closed position, the cable 45 in the chamber body 44 is received. By using the cable 45 to connect the solar panel 6 and the electric component, the problems of electrolysis and corrosion of the conducting structure are solved, and the service life of the conducting structure of the solar panel 6 can be effectively extended to ensure the working stability of the solar panel 6.

The chamber body 44 has an elongated shape extending in the moving direction of the upper cover 4. Preferably, the cable 45 is a helical cable in order to be accommodated in the chamber body 44 orderly. The helical cable may be orderly stretched or compressed within the chamber body 44.

Furthermore, a winding post 46, a carrier plate 47 or other structure for carrying the helical cable is also provided in the chamber body 44, and the helical cable can be arranged around the winding post 46 or placed on the carrier plate due to gravity, and in this case, the cable 45 can be better and more orderly accommodated in the chamber body 44, thereby avoiding any unreliable influencing factors caused by the excessive length of the cable body. As an example of the provision of the winding post 46, when the upper cover 4 moves from the open position to the closed position, the stretched cable 45 can be retracted in an orderly manner due to the guiding action of the winding post 46, thereby allowing the thread pitch to gradually decrease, and the cooperation of the winding post 46 with the helical cable can ensure that thread jamming does not occur to the upper cover 4 during sliding.

It could be appreciated that when the carrier plate 47 is provided in the chamber body 44, an open slot 471 is provided on the carrier plate 47 so that one end of the cable 45 can be connected to an electrical component in the main body 1 through the open slot 471, the length direction of the open slot 471 being consistent with the sliding direction of the upper cover 4, and the length of the open slot 471 being defined by the displacement amount of the upper cover 4. The carrier plate 47 having the open slot 471 is simple in structure and convenient to manufacture. During a specific production process, the carrier plate 47 can be either integrally injection-molded with other areas of the upper cover 4 or connected to the upper cover 4 by means of a fastener, and the specific choice is made according to actual needs.

It needs to be noted that in this illustration, for clarity of illustration of the different implementation modes, both the winding post 46 and the carrier plate 47 are provided. In particular implementation, only the winding post 46 and only the carrier plate 47 can be provided on the upper cover 4, and in other implementations, the winding post 46 and the carrier plate 47 having the opening slot 471 can also be provided together, and are specifically selected according to actual needs.

When a carrier plate 47 is provided in the chamber body 44, it is preferred that the cross-sectional dimension of the chamber body 44 is only slightly larger than the overall outer diameter of the cable 45 in the contracted state, and that the cable 45 does not overlap itself during the reset of the cable 45 from the stretched state to the retracted state, thereby ensuring that the stretched cable 45 can be retracted in an orderly manner, and thus allowing the thread pitch to gradually reduce.

When it needs to be stated, in a specific product, it is also possible that the rechargeable battery 12 is not provided on the product; and in this case, the solar controller connects the solar panel 6 with the electric component in the water surface cleaning robot, such as the driving mechanism 3, the rotating motor 81, etc. That is to say, in this case, the electric component in the water surface cleaning robot is directly powered by the solar panel 6 or is powered by the solar panel 6 assisted mains supply/mobile power supply.

With reference to FIGS. 5, and 15 to 20, in order to prevent the water surface cleaning robot from stranding during operation, the bottom face of the main body 1 is provided with an anti-stranding device 7.

In other embodiments, the anti-stranding device 7 may also be an interference structure of the non-electronic sensor type, in which case the anti-stranding device 7 achieves anti-stranding by direct interference with structures such as steps in the working environment.

With reference to FIGS. 15 to 18, in one embodiment, the main body 1 has an oppositely arranged mounting portion 17, the mounting portion 17 is provided with a shaft hole, a rotary shaft 71 is provided at the shaft hole, the anti-stranding device 7 is rotatably connected to the main body 1 via the rotary shaft 71, and a limiting piece 72 for limiting the axial sliding of the rotary shaft 71 is mounted on the rotary shaft 71. When the anti-stranding device 7 is mounted, firstly, the rotary shaft 71 is penetrated from the outer side of one mounting portion 17, and one end of the rotary shaft 71 passes through the anti-stranding device 7 and another mounting portion 17 in sequence, then the limiting piece 72 is fixed on the rotary shaft 71. When the rotary shaft 71 moves axially, the limiting piece 72 fixed on the rotary shaft 71 abuts against the anti-stranding device 7 and/or the mounting portion 17, thereby limiting the axial sliding of the rotary shaft 71. Optionally, the limiting piece 72 has a bayonet, the rotary shaft 71 has a snap slot that matches the bayonet, and the limiting piece 72 is connected to the rotary shaft 71 by means of a snap connection, so that it is more convenient to assemble and disassemble the limiting piece 72 and the rotary shaft 71. In the present embodiment, the limiting piece 72 has a concave shape, and the limiting piece 72 is provided with two of the bayonets, so that not only the production consumables of the limiting piece 72 can be reduced, but also the limiting piece 72 can be more conveniently disassembled and assembled by a user.

Optionally, the anti-stranding device 7 is grooved in cross-section. In some embodiments, the dampening structure may be received in a groove of the anti-stranding device 7. In the present embodiment, the limiting piece 72 is accommodated in a groove of the anti-stranding device 7.

The water surface cleaning robot further includes a third limiting structure, where the third limiting structure includes a first limiting portion and a second limiting portion which cooperate with each other, the first limiting portion is provided on the anti-stranding device 7, the second limiting portion is provided on the main body 1, and the cooperation of the first limiting portion and the second limiting portion can enable the anti-stranding device 7 to maintain a relative positional relationship with the main body 1 so as to avoid an unexpected movement of the anti-stranding device 7 relative to the main body 1.

Optionally, the first limiting portion includes a first abutting face 73 and a second abutting face 74 arranged at an included angle, and the second limiting portion is an elastic abutting portion arranged on the main body 1.

In detail, the elastic abutting portion is an elastic arm 18 provided on the main body 1, and in some embodiments, the elastic abutting portion may be an elastic pad or the like provided on the main body 1, and the elastic pad includes but is not limited to a metal elastic pad, a rubber pad and the like. In other embodiments, the first limiting portion and the second limiting portion may have other structural forms, such as a concave-convex fitting structure.

The bottom of the main body 1 is equipped with an accommodating slot 19 for accommodating the anti-stranding device 7. In this embodiment, the mounting portion 17 is a side wall of the accommodating slot 19, and the elastic arm 18 is a partial region of a bottom wall of the accommodating slot 19.

The anti-stranding device 7 does not have to be rotatable with respect to the main body 1 in order to take a step back. As shown in FIGS. 19 and 20, in other embodiments, it is also possible that the anti-stranding device 7 is liftable with respect to the main body 1. When the anti-stranding function of the water surface cleaning robot is switched on, the anti-stranding device 7 descends and extends out of the accommodating slot 19, and when the anti-stranding function of the water surface cleaning robot is switched off, the anti-stranding device 7 ascends and retracts into the accommodating slot 19.

As an instance of a liftable anti-stranding device 7, the accommodating slot 19 on the main body 1 is in communication with the outside at the bottom face of the main body 1. Preferably, the accommodating slot 19 is arranged in the vertical direction, an elastic clamping block 75 is provided on the anti-stranding device 7, a plurality of clamping holes 191 in communication with the accommodating slot 19 are provided on the wall face of the main body 1, the clamping hole 191 cooperates with the clamping block 75, and when the clamping block 75 cooperates with different clamping holes 191, the protruding distance of the anti-stranding device 7 with respect to the bottom face of the main body 1 is different. Preferably, the same accommodating slot 19 is in communication with two of the clamping holes 191; when the clamping block 75 is clamped into one of the clamping holes 191, the anti-stranding device 7 is accommodated in the accommodating slot 19; and when the clamping block 75 is clamped into the other of the clamping holes 191, the bottom end of the anti-stranding device 7 protrudes relative to the bottom face of the main body 1, so as to perform the function of anti-stranding. As will be readily appreciated, in a particular operation, a user can unlock the anti-stranding device 7 by pressing directly on the clamping block 75 snapped into the clamping hole 191, so that the anti-stranding device 7 can slide along the accommodating slot 19. At that, the clamping block 75 snaps into the other clamping hole 191.

After the anti-stranding device 7 is turned on, when the water surface cleaning robot encounters a step or the water surface cleaning robot travels to a relatively shallow water area, the anti-stranding device 7 will be triggered, so as to transfer a signal to a controller of the water surface cleaning robot, and the controller controls the water surface cleaning robot to take a step back or turn, so as to prevent the water surface cleaning robot from rushing into a shallow water area.
