[0024] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0025] Figures 1A-1C The figure schematically shows the appearance of an automatic water surface cleaning device 10 according to an embodiment of the present disclosure. The automatic water surface cleaning device 10 can clean the water surface of the pool as needed, for example, to clean up garbage and debris on the water surface. Figures 1A-1C As shown, the automatic water surface cleaning device 10 may include a shell 110, which has a roughly boat-shaped appearance, wherein the shell 110 includes a front end 120 located close to the direction of travel of the automatic water surface cleaning device and a rear end 130 away from the direction of travel of the automatic water surface cleaning device.

[0026] As an example, Figure 1A and Figure 1B As further shown, the automatic water surface cleaning device 10 also includes flow channels 140 symmetrically arranged on both sides of the housing 110 and a propulsion device 150 disposed in the flow channels 140. As an example, the propulsion device 150 may include a propeller driven by a motor. According to an embodiment of the present disclosure, the automatic water surface cleaning device 10 can be driven by the propulsion device to perform various actions such as forward, backward, and turning on the water surface to clean various garbage and debris floating on the water surface, such as fallen leaves.

[0027] like Figures 1A-1C As shown, a water inlet 160 is provided at the front end of the housing 110 of the automatic water surface cleaning device 10 , and drain outlets 190 and 195 are provided at the rear end and bottom of the housing 110 , respectively.

[0028] Figure 1A It is further shown that the automatic water surface cleaning device 10 includes at least one rotatable component 170 , 180 arranged at the front end thereof, which can rotate in a first direction or a second direction to guide garbage into the water inlet 160 .

[0029] According to an embodiment of the present disclosure, the automatic water surface cleaning device may further include: a filtering device, at least partially located in the shell, the filtering device being capable of filtering the water flow entering the interior thereof through the water inlet, intercepting garbage carried in the water in the filtering device, and discharging the filtered water through the at least one drain outlet.

[0030] Figure 2A Schematically shows a portion of the internal structure of the automatic water surface cleaning device 20 according to an embodiment of the present disclosure after removing the top cover and the front cover of the housing 110. Figure 2A As shown, the automatic water surface cleaning device 20 may include a detachable filter device 21 at least partially located inside the housing 110. When the automatic water surface cleaning device moves on the water surface, the water flow in front of it can enter the filter device 21 through the water inlet, thereby intercepting garbage carried in the water flow inside the filter device 21, and the filtered water can be discharged into the pool.

[0031] As an example, Figure 2A As further shown, the interior of the automatic water surface cleaning device also includes buoyancy mechanisms 215 and 225 symmetrically arranged on both sides of the filter device 21. By providing the buoyancy mechanisms, buoyancy can be provided for the automatic water surface cleaning device to be suspended on the water surface. As an example, the buoyancy mechanisms 215 and 225 can be in the form of air bags, air chambers, etc., and the buoyancy adjustment mechanism such as an air pump can be controlled by the control unit of the automatic water surface cleaning device 20 to adjust the buoyancy provided by the buoyancy mechanisms 215 and 225. As an example, the control unit can be a control circuit such as a microprocessor, a digital signal processor (DSP), or a microcontroller.

[0032] Figure 2B The bottom shape of the automatic water surface cleaning device 20 according to the embodiment of the present disclosure is schematically shown. Figure 2B As shown, when the filter device 21 is installed on the automatic water surface cleaning device 20 , the bottom frame of the filter device 21 can serve as a part of the housing 210 of the automatic water surface cleaning device 20 .

[0033] Figures 2C-2D The figure schematically shows the appearance of the filter device 21. Figure 2CAs shown, the filtering device 21 may include a main structure 210, wherein the main structure includes a water inlet and at least one water outlet; as an example, Figure 2C As shown, a water inlet 220 is provided at the front end of the main structure 210, and the bottom of the main structure may be a frame structure having at least one opening, on which a water outlet 230 is provided; Figure 2D As shown, the rear end of the main structure 210 may be a frame structure having at least one opening, on which a water outlet 240 is provided.

[0034] In addition, a filter net (not shown) is provided at the openings at the bottom and rear end of the main structure 210, for example, at the water outlets 230 and 240. The filter net can filter the water flow entering the interior through the water inlet 220 of the main structure 210, intercept the garbage carried in the water within the main structure, and discharge the filtered water through the at least one water outlet 230, 240.

[0035] like Figures 2C-2D As further shown, the filter device 21 may also include an openable top cover 260 so that garbage trapped in the main structure 210 can be cleaned.

[0036] It can be understood that the water inlet 220 of the main structure 210 can be communicated with the water inlet 160 of the shell, and the water outlets 230 and 240 of the filter device can be communicated with the water outlets 190 and 195 of the shell.

[0037] According to an embodiment of the present disclosure, the automatic water surface cleaning device may further include: a shielding mechanism, which is arranged at the head of the automatic water surface cleaning device and can be switched between an open state and a closed state, wherein, in the open state, the shielding mechanism opens at least a portion of the water inlet so that water can flow into the filter device through the water inlet, and in the closed state, the shielding mechanism blocks at least a portion of the water inlet to prevent garbage trapped in the filter device from overflowing through the water inlet; and a driving mechanism, which is configured to drive the at least one rotatable component to rotate in a first direction or a second direction, and drive the shielding mechanism to switch between an open state and a closed state.

[0038] Figures 3A-3B The schematic diagram shows the connection structure of the filter device, at least one rotatable component and the driving mechanism of the automatic water surface cleaning device according to the embodiment of the present disclosure. As an example, Figure 3A Two rotatable components, namely, a first rotatable component 270 and a second rotatable component 280 , are schematically shown, which are disposed at the front end of the main structure 210 of the filter device 21 .

[0039] like Figure 3AAs schematically shown, the first rotatable assembly 270 and the second rotatable assembly 280 may be disposed at different heights at the front end of the main structure 210 .

[0040] like Figure 3A As shown, the rotatable components 270 and 280 can rotate under the drive of the driving mechanism 28. As an example, the first rotatable component 270 and the second rotatable component 280 are linked to each other and are configured to be relatively rotatable.

[0041] The first rotatable component 270 and the second rotatable component 28 rotating relative to each other can bring garbage on the path of the automatic water surface cleaning device into the filtering device 21, and the rotatable component located at a lower position can bring semi-floating garbage in the pool into the filtering device 21.

[0042] Figure 3B The figure schematically shows the matching connection structure between the filter device 21 and the driving mechanism on the other side of the filter device 21 of the automatic water surface cleaning device according to an embodiment of the present disclosure.

[0043] According to an embodiment of the present disclosure, the positions of the first rotatable component and the second rotatable component along the forward direction of the automatic water surface cleaning device may be different.

[0044] Figure 3C The cross-sectional structure of the filter device 21 of the automatic water surface cleaning device according to the disclosed embodiment along the longitudinal direction from the front end to the rear end is schematically shown. Figure 3C As shown in FIG, the rotation axes of the first rotatable component 270 and the second rotatable component 280 are staggered in the horizontal direction. In other words, the second rotatable component 280 is closer to the front end of the filter device 21 than the first rotatable component 270.

[0045] In addition, according to an embodiment of the present disclosure, the diameters of the first rotatable component and the second rotatable component can also be set to be different. Two rotatable components with different diameters can clean different types of garbage and achieve more comprehensive cleaning. Figure 3C As shown, the diameter of the first rotatable component 270 is larger than the diameter of the second rotatable component 280 .

[0046] The first rotatable component and the second rotatable component arranged in this way enable the automatic water surface cleaning device to clean garbage more efficiently, reduce cleaning blind spots, improve garbage guiding capabilities, enhance system stability, and help extend the service life of the equipment.

[0047] Figures 4A-4B The figure schematically shows the cooperative connection structure between the filtering device of the automatic water surface cleaning device according to the embodiment of the present disclosure and at least one rotatable component, the driving mechanism and the shielding mechanism.

[0048] Figure 4A The figure schematically shows the appearance of the filter device 21 after the top cover 260 is removed according to an embodiment of the present disclosure. Figure 4A As shown, the second rotatable component 280 can be positioned further forward than the first rotatable component 270 along the forward direction of the automatic water surface cleaning device (as shown by the dotted arrow).

[0049] According to an embodiment of the present disclosure, depending on the application scenario of the automatic water surface cleaning device, the rotatable component may include a roller brush or a dial. Figure 4A The first rotatable component 270 and the second rotatable component 280 shown in the figure both adopt the structure of the dial wheel. However, at least one of the first rotatable component 270 and the second rotatable component 280 may also adopt the structure of a roller brush, which is not limited here.

[0050] In addition, despite Figure 3A and Figure 4A In the figure, it is schematically shown that the automatic water surface cleaning device includes two rotatable components 270 and 280 as water flow guiding mechanisms, namely, a first rotatable component 270 and a second rotatable component 280. However, depending on the application scenario of the automatic water surface cleaning device and the structural size of the body, only one of the rotatable components may be used, for example, only the first rotatable component 270, which is not limited here.

[0051] like Figures 4B-4C As schematically shown, the shielding mechanism 290 can be provided at the front end of the main structure 210 of the filter device 21 and can be switched between an open state and a closed state, wherein, in the open state, the shielding mechanism opens at least a portion of the water inlet so that water can flow into the filter device through the water inlet, and in the closed state, the shielding mechanism blocks at least a portion of the water inlet to prevent garbage trapped in the filter device from overflowing through the water inlet.

[0052] Figure 4B The shielding mechanism 290 is schematically shown in an open state. In this state, a portion of the water inlet is opened, thereby allowing water to flow into the main structure 210 through the water inlet. Figure 4C The shielding mechanism 290 is schematically shown in a closed state. In this state, a portion of the water inlet is shielded by the shielding mechanism 290 to prevent garbage trapped in the main structure 210 from overflowing through the water inlet.

[0053] As an example, although Figures 4B-4CIt is shown that the shielding mechanism 290 adopts a baffle structure, however, the shielding mechanism may also adopt other structures, as long as it can switch between the open and closed states by rotation, so that in the open state, the water flow carrying garbage can enter the main structure 210 through the water inlet, and in the closed state, it can prevent the garbage trapped inside the main structure 210 from overflowing through the water inlet. There is no limitation here.

[0054] like Figures 3A-4C As schematically shown, the automatic water surface cleaning device according to an embodiment of the present disclosure may include a driving mechanism 28, which is configured to drive the at least one rotatable component 270, 280 to rotate in the first direction or the second direction, and drive the shielding mechanism 290 to switch between an open state and a closed state.

[0055] According to at least one embodiment of the present disclosure, the driving mechanism includes a driving motor, a first transmission mechanism and a second transmission mechanism, the first transmission mechanism is used to transmit the driving force of the driving motor to the at least one rotatable component to rotate it, and the second transmission mechanism is used to transmit the driving force of the driving motor to the shielding mechanism to switch the switch state.

[0056] According to at least one embodiment of the present disclosure, the first transmission mechanism and the second transmission mechanism are located on the same side of the cleaning device.

[0057] According to at least one embodiment of the present disclosure, the shielding mechanism switches the switch state by a rotation action.

[0058] According to at least one embodiment of the present disclosure, the first transmission mechanism includes a first gear, the second transmission mechanism includes a second gear, the outer ring surface of the second gear includes a first surface and a second surface, the first gear can engage and rotate with the first surface, and the second surface does not contact the first gear.

[0059] like Figures 4A-4C As shown, one end of the first rotatable component 270 serving as a roller brush or a dial passes through the main structure 210 and is sleeved with a first gear 310 , and one end of the shielding mechanism 290 passes through the main structure 210 and is sleeved with a second gear 320 .

[0060] According to an embodiment of the present disclosure, the first transmission mechanism includes a first gear 310, and the second transmission mechanism includes a second gear 320. Figures 4A-4CAs shown, the second gear 320 is meshed with the first gear 310 via the fourth gear 340 and the fifth gear 350. Thus, when the first gear 310 is driven by the driving motor to rotate, the second gear 320 can be driven to rotate via the fourth gear 340 and the fifth gear 350, thereby driving the shielding mechanism 290 to rotate. Thus, the shielding mechanism 290 can be driven to rotate by the driving motor so that the shielding mechanism 290 can be switched between the open state and the closed state, for example, Figure 4B The open state shown and Figure 4C toggles between the on and off states shown.

[0061] Thus, the first rotatable component, which is a roller brush or a dial, can be rotated together with the shielding mechanism under the drive of the same drive motor.

[0062] like Figure 5 As shown, the other end of the first rotatable component 270 passes through the main structure 210 and is sleeved with a sixth gear 360. The sixth gear 360 can be driven by a drive motor 410 (see FIG. 4 ) provided inside the housing of the water surface automatic cleaning device. Figure 2A and Figure 5 ) is driven to rotate. For example, Figure 5 As shown, the drive motor 410 can drive the sixth gear 360 via the transmission gear 420 engaged with the sixth gear 360, thereby driving the first rotatable component 270 to rotate in the first direction or the second direction. For example, the first direction can be clockwise and the second direction can be counterclockwise.

[0063] When the sixth gear 360 is driven by the driving motor 410 to rotate, the first gear 310 provided at the other end of the first transmittable component 270 rotates synchronously.

[0064] It should be noted that although Figures 4A-4C It is shown in the figure that the first gear 310 drives the second gear 320 via the fourth gear 340 and the fifth gear 350 which serve as intermediate transmission gears. However, depending on the relative rotation direction, relative rotation speed and / or the body size of the automatic water surface cleaning device of the first rotatable component 270 and the shielding mechanism 290, the number of intermediate transmission gears is not limited to two; alternatively, the fourth gear 340 and the fifth gear 350 which serve as intermediate transmission gears can be eliminated, that is, the first gear 310 is directly meshed with the second gear 320.

[0065] In addition, if Figures 4A-4CAs shown, the second gear 320 adopts a semi-tooth structure, that is, gear teeth are provided only on a portion of the circumference of the second gear 320. The gear teeth of this portion can mesh with the fifth gear 350, while the portion of the circumference of the second gear 320 without gear teeth does not contact the fifth gear 350. In other words, the first gear 310 can mesh with the portion of the outer surface of the second gear 320 with gear teeth via the fourth gear 340 and the fifth gear 350, which serve as intermediate transmission gears, without contacting the other portions of the outer surface of the second gear 320.

[0066] With this structure, the shielding mechanism 290 can be rotated only within a certain angle without affecting the continuous rotation of the first rotatable component 270 .

[0067] Specifically, if Figures 4A-4C As shown, the first rotatable component 270 can rotate in the first direction or the second direction under the drive of the drive motor, thereby driving the first gear 310 to rotate synchronously. The first gear 310 can transmit the driving force to the second gear 320 through the fourth gear 340 and the fifth gear 350 serving as intermediate transmission gears.

[0068] For example, when the first rotatable component 270 rotates forward (e.g., Figures 4A-4C When the gear rotates counterclockwise in the direction shown in the figure), the automatic water surface cleaning device can clean up the garbage normally; the driving force from the first gear 310 is transmitted to the second gear 320 through the fourth gear 340 and the fifth gear 350; Figure 4B As shown, the rotation direction of the fifth gear 350 is the same as the rotation direction of the first gear 310, that is, counterclockwise. Through the engagement of the gear teeth of the fifth gear with the gear teeth of the second gear 320, the second gear 320 is driven to rotate clockwise, thereby pressing the shielding mechanism 290 downward, so that the shielding mechanism 290 is in an open state, the water inlet of the main structure 210 is opened, and the water flow carrying garbage can enter the interior of the main structure 210 through the water inlet. Since gear teeth are only provided on a part of the circumference of the second gear 320, when the second gear 320 rotates clockwise so that its leftmost gear teeth contact the fifth gear 350 (this position can be referred to as the right limit position of the second gear 320), even if the fifth gear 350 continues to rotate counterclockwise, since the part of the second gear 320 without gear teeth does not contact the gear teeth of the fifth gear 350, the second gear 320 slips, and the power from the fifth gear 350 cannot continue to be transmitted to the shielding mechanism 290, and the shielding mechanism 290 remains in a downward state, and the first rotatable component 270 continues to rotate counterclockwise without being affected.

[0069] When the first rotatable component 270 is reversed (for example, Figures 4A-4CWhen the first gear 310 rotates clockwise in the direction shown in FIG, the driving force from the first gear 310 is transmitted to the second gear 320 through the fourth gear 340 and the fifth gear 350; Figure 4C As shown, the rotation direction of the fifth gear 350 is the same as that of the first gear 310, that is, clockwise. Through the engagement of the gear teeth of the fifth gear with the gear teeth of the second gear 320, the second gear 320 is driven to rotate counterclockwise, thereby lifting the shielding mechanism 290, so that the shielding mechanism 290 is in a closed state, and the water inlet of the main structure 210 is blocked, thereby preventing the garbage trapped inside the main structure 210 from overflowing through the water inlet. Since gear teeth are only provided on a part of the circumference of the second gear 320, when the second gear 320 rotates counterclockwise so that its rightmost gear teeth contact the fifth gear 350 (this position can be referred to as the left limit position of the second gear 320), even if the fifth gear 350 continues to rotate clockwise, since the part of the second gear 320 without gear teeth does not contact the gear teeth of the fifth gear 350, the second gear 320 slips, and the power from the fifth gear 350 cannot continue to be transmitted to the shielding mechanism 290, and the shielding mechanism 290 remains in a lifted state, while the first rotatable component 270 continues to rotate clockwise without being affected.

[0070] In addition, according to an embodiment of the present disclosure, in order to enable the second gear 320 to better realize forward and reverse switching, a reverse force can be applied to the left and right extreme positions of the second gear 320. Figures 4A-4C As shown, the driving structure may further include an elastic member 370, which may be arranged on the outside of the main structure 210. When the second gear 320 rotates to the left / right limit position, the elastic member 370 may contact the convex portion arranged on the circumference of the second gear 320, thereby applying a reverse force to the second gear 320 at the left / right limit position, thereby facilitating the forward / reverse switching of the second gear 320.

[0071] As an example, the elastic member 370 may be a spring sheet.

[0072] According to the embodiments of the present disclosure, Figure 4B As shown, a convex portion is provided on the circumference of the second gear 320, and an elastic member is provided on the main structure 210. When the second gear 320 is at the right extreme position, the elastic member 370 contacts the convex portion to apply an elastic force to the movable baffle to flip it and close the water inlet.

[0073] In addition, if Figure 4AAs shown, when at least one rotatable component includes a second rotatable component 280, one end of the second rotatable component 280 passes through the main structure 210 and is fitted with a third gear 330. As an example, the third gear 330 meshes with the first gear 310 via a fourth gear 340 and a fifth gear 350, which serve as intermediate transmission gears. Thus, when the first gear 310 rotates, the fourth gear 340 and the fifth gear 350, which serve as intermediate transmission gears, drive the third gear 330 to rotate, thereby driving the second rotatable component 280 to rotate. The meshing of the fourth gear 340 and the fifth gear 350 allows the third gear 330 to rotate in the opposite direction to that of the first gear 310; that is, the second rotatable component 280 rotates in the opposite direction to that of the first rotatable component 270.

[0074] It should be noted that although Figures 4A-4C It is shown in the figure that the first gear 310 drives the third gear 330 via the fourth gear 340 and the fifth gear 350 which serve as intermediate transmission gears. However, depending on the relative rotation direction, relative rotation speed and / or the body size of the automatic water surface cleaning device of the first rotatable component and the second rotatable component, the number of intermediate transmission gears is not limited to two; alternatively, the fourth gear 340 and the fifth gear 350 which serve as intermediate transmission gears can be eliminated, that is, the third gear 330 is directly meshed with the first gear 310.

[0075] In addition, it should be noted that at least one of the rotatable components, shielding mechanism and / or driving mechanism of the automatic water surface cleaning device can be integrated with the filtering device to form an integral structure, so that when the filtering device is installed on the automatic water surface cleaning device, it can be installed as an integrated unit; or at least one of them can be set as a structure that can be separated from the filtering device, that is, it can be installed on the housing of the automatic water surface cleaning device separately from the filtering device, and there is no restriction here.

[0076] According to an embodiment of the present disclosure, the automatic water surface cleaning device is further provided with a limiting mechanism, and the limiting structure is used to limit the rotation range of the shielding mechanism. Figure 4B and 4C As shown, the limiting mechanism may include: a first limiting mechanism 2910 and a second limiting mechanism 2920, wherein the first limiting mechanism 2910 corresponds to the position when the shielding mechanism 290 is fully opened, and the second limiting mechanism 2920 corresponds to the position when the shielding mechanism 290 is fully closed, that is, the first limiting mechanism 2910 and the second limiting mechanism 2920 limit the rotation range of the shielding mechanism 290.

[0077] According to the automatic water surface cleaning device of the embodiment of the present disclosure, the rotatable component serving as the roller brush or the dial wheel and the shielding mechanism located at the water inlet can be driven by the same drive motor, so that when the roller brush or the dial wheel of the automatic water surface cleaning device rotates in a first direction, the driving force of the driving roller brush or the dial wheel can be used to press the shielding mechanism downward to open, so that the water flow carrying garbage can enter the filter device, ensuring a smooth cleaning channel; and when the roller brush or the dial wheel rotates in a second direction, the driving force of the driving roller brush or the dial wheel can be used to lift and close the shielding mechanism to prevent the garbage trapped in the filter device from overflowing through the water inlet. In addition, when the automatic water surface cleaning device is not working and is floating on the water surface without power, the driving motor can be used in advance to drive the shielding mechanism to lift and close to prevent the garbage collected in the filter device from overflowing.
