Description

Technical Field

[0001] This application relates to the field of water surface garbage cleaning equipment technology, and in particular to a water surface cleaning robot. Background Technology

[0002] As a place for swimming, the water quality of a swimming pool directly affects the health and experience of its users. However, swimming pools inevitably accumulate various types of debris during use, such as fallen leaves, junk, shed hair, and skin flakes. This debris not only affects the pool's aesthetics but also negatively impacts water quality. The decomposition of this debris in the water consumes dissolved oxygen, leading to oxygen deficiency and creating conditions for the growth of anaerobic microorganisms. This, in turn, causes water quality deterioration, produces unpleasant odors, and may even spread germs, threatening the health of swimmers.

[0003] To effectively address the problem of pool debris, surface cleaning robots have emerged. With their automation and high efficiency, they have become an important tool for pool cleaning, quickly collecting surface debris and maintaining water cleanliness. However, current surface cleaning robots still have significant shortcomings in practical applications. When the robot approaches the pool edge, the complex terrain, varying slopes, and unstable water flow near the shore can easily cause it to become stranded. Once stranded, the robot cannot continue its cleaning work, interrupting the process. This not only increases the cost and time of manual intervention but also reduces the robot's cleaning efficiency. Utility Model Content

[0004] The main objective of this application is to propose a water surface cleaning robot with anti-sanding function, which aims to improve the stability of the water surface cleaning robot when performing cleaning operations in water.

[0005] To achieve the above objectives, this application discloses a water surface cleaning robot, including a shell and a power device for driving the shell to move on the water surface. A receiving cavity is provided on the side wall of the shell, and a stop block is movably disposed in the receiving cavity. The stop block can extend out of the receiving cavity toward the bottom of the shell.

[0006] In some embodiments, a guide plate is provided on the receiving cavity, and a guide groove is provided on the guide plate. The stop block includes a base plate and a pressing plate. The guide plate is located between the base plate and the pressing plate, and the base plate and the pressing plate can move along the setting direction of the guide groove.

[0007] In some embodiments, an elastic sheet is movably disposed on the substrate, and the guide plate is sandwiched between the pressing plate and the elastic sheet. The pressing plate can move closer to or away from the elastic sheet, and the elastic sheet is inserted into or removed from the guide groove as the pressing plate moves.

[0008] In some embodiments, the elastic sheet is provided with a protrusion on the side facing the pressing plate, and the first and second positioning holes that match the protrusion are provided at both ends of the guide groove.

[0009] In some embodiments, the stop block further includes a base plate and a finger hole, the finger hole being disposed above the base plate, and anti-slip strips being provided on both the upper and lower surfaces of the base plate.

[0010] In some embodiments, there are two receiving cavities, which are respectively located on the left and right sides of the end of the housing near the direction of travel.

[0011] In some embodiments, a cushioning pad is provided on the end of the housing near the direction of travel.

[0012] In some embodiments, a controller is provided inside the housing, and a collision sensor is also provided on the housing, which can transmit signals to the controller.

[0013] In some embodiments, a battery is also provided inside the housing, and there is an electrical connection between the battery, the power unit, and the controller.

[0014] In some embodiments, a removable trash basket is also provided inside the housing for storing trash.

[0015] This application proposes a water surface cleaning robot, including a shell and a receiving cavity disposed on the side wall of the shell. By setting a stop block on the shell that can extend or retract into the receiving cavity, the stop block is operated to extend into the receiving cavity. When the water surface cleaning robot travels to the edge of the pool, the stop block will first interfere with the pool wall or other structures at the edge of the pool, thereby preventing the water surface cleaning robot from being washed ashore by the water flow, thus preventing it from getting stranded. This allows the water surface cleaning robot to perform cleaning work stably and continuously, improving the overall reliability. Attached Figure Description

[0022] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the stop block 1200 extending out of the receiving cavity 1100 in this embodiment. Figure 2for Figure 1 A magnified view of a portion of point A in the diagram. Figure 3 This is a schematic diagram of the stop block 1200 retracting into the receiving cavity 1100 in this embodiment. Figure 4 for Figure 3 A partially enlarged schematic diagram at point B. This application provides a water surface cleaning robot, including a housing 1000 and a power device for driving the housing 1000 to move on the water surface. A receiving cavity 1100 is provided on the side wall of the housing 1000, and a stop block 1200 is movably disposed in the receiving cavity 1100. The stop block 1200 can extend out of the receiving cavity 1100 toward the bottom of the housing 1000.

[0023] In this embodiment, the water surface cleaning robot includes a housing 1000, a power unit, and a receiving cavity 1100. The power unit is mounted on the housing 1000 and provides the robot with the power to move on the water surface, enabling it to clean up debris. The receiving cavity 1100 is formed in the side wall of the housing 1000, and a stop block 1200 is movably installed within the receiving cavity 1100, extending out of the receiving cavity 1100 towards the bottom of the housing 1000.

[0024] In this embodiment, a stop block 1200 that can extend or retract into the receiving cavity 1100 is provided on the housing 1000. The operator can decide whether to activate the anti-sanding function according to the actual usage needs. Specifically, when the stop block 1200 extends out of the receiving cavity 1100, the anti-sanding function is activated. When the water surface cleaning robot moves to the edge of the pool, the stop block 1200 will interfere with the pool wall and other structures at the edge of the pool, thereby preventing the water surface cleaning robot from being washed ashore by the water flow, thus achieving the effect of preventing sanding.

[0025] Understandably, when the anti-sanding function is not needed, it is sufficient to retract the stop block 1200 into the receiving cavity 1100.

[0026] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the receiving cavity 1100 in this embodiment. Figure 6 for Figure 5 A partially enlarged schematic diagram at point C. In some embodiments, a guide plate 1110 is provided on the receiving cavity 1100, and a guide groove 1111 is provided on the guide plate 1110. The stop block 1200 includes a base plate 1210 and a pressing plate 1220. The guide plate 1110 is located between the base plate 1210 and the pressing plate 1220. The base plate 1210 and the pressing plate 1220 can move along the setting direction of the guide groove 1111.

[0027] In this embodiment, each receiving cavity 1100 is further provided with a guide plate 1110, and a guide groove 1111 is provided through the guide plate 1110. The guide groove 1111 plays a guiding role in the movement of the stop block 1200. Specifically, the stop block 1200 includes a base plate 1210 and a pressing plate 1220 mounted on the base plate 1210. When the stop block 1200 is installed in the receiving cavity 1100, the guide plate 1110 is located in the gap between the base plate 1210 and the pressing plate 1220, and a portion of the base plate 1210 and the pressing plate 1220 are embedded in the guide groove 1111 of the guide plate 1110, so that the stop block 1200 is movably installed in the receiving cavity 1100. Under the action of the guide groove 1111 on the guide plate 1110, the stop block 1200 can reciprocate along the setting direction of the guide groove 1111, thereby realizing the function of the stop block 1200 extending or retracting into the receiving cavity 1100. In this way, when the water surface cleaning robot is cleaning in the pool, the operator can extend the stop block 1200 from the housing 1000 towards the bottom of the water, preventing the water surface cleaning robot from being washed ashore by the water flow and avoiding stranding. This ensures that the water surface cleaning robot can carry out cleaning work stably and continuously, improving the overall reliability.

[0028] Please see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the stop block 1200 in this embodiment. Figure 8 This is a schematic diagram of the structure of the elastic sheet 1211 and the protrusion 1212 in this embodiment. In some embodiments, the elastic sheet 1211 is movably disposed on the substrate 1210, and the guide plate 1110 is sandwiched between the pressing plate 1220 and the elastic sheet 1211. The pressing plate 1220 can move closer to or away from the elastic sheet 1211, and the elastic sheet 1211 is inserted into or removed from the guide groove 1111 as the pressing plate 1220 moves.

[0029] In some embodiments, the elastic sheet 1211 is provided with a protrusion 1212 on the side facing the pressing plate 1220, and the guide groove 1111 is provided with a first positioning hole 1112 and a second positioning hole 1113 that match the protrusion 1212 at both ends.

[0030] In some embodiments, the stop block 1200 further includes a base plate 1230 and a finger hole 1240, the finger hole 1240 being disposed above the base plate 1230, and anti-slip strips 1231 being provided on both the upper and lower surfaces of the base plate 1230.

[0031] In this embodiment, an elastic sheet 1211 is provided on the substrate 1210. The first end of the elastic sheet 1211 is connected to the substrate 1210, and the second end of the elastic sheet 1211 can move closer to or further away from the pressing plate 1220. When the stop block 1200 is installed in the receiving cavity 1100, the second end of the elastic sheet 1211 and the pressing plate 1220 together clamp the guide plate 1110. Specifically, a protrusion 1212 is provided on the elastic sheet 1211, and a protrusion matching the position of the protrusion 1212 is provided on the side of the pressing plate 1220 facing the elastic sheet 1211. The protrusion 1212 of the elastic sheet 1211 and the protrusion of the pressing plate 1220 are both embedded in the guide groove 1111 of the guide plate 1110. A first positioning hole 1112 and a second positioning hole 1113 are respectively provided at both ends of the guide groove 1111, with the first positioning hole 1112 located above the second positioning hole 1113.

[0032] Here, a finger hole 1240 is also provided on the side of the stop block 1200 near the base plate 1230. The finger hole 1240 is located above the base plate 1230, and the side wall of the finger hole 1240 near the bottom of the stop block 1200 is the upper surface of the base plate 1230. Anti-slip strips 1231 are provided on both the upper and lower surfaces of the base plate 1230, and the upper surface of the base plate 1230 is the side wall of the finger hole 1240. In this way, the user can more easily apply force to the stop block 1200, thereby making it easier for the operator to operate the stop block 1200 to extend or retract into the receiving cavity 1100.

[0033] In practical use, such as Figure 2 and Figure 4 As shown, Figure 2 This is the state where the anti-strand function is enabled. Figure 4 To prevent the stranding function from being activated. When the water surface cleaning robot is not in the water or when the stranding function is not required, the protrusion 1212 on the elastic sheet 1211 is embedded in the first positioning hole 1112 at the upper end of the guide groove 1111. The protrusion 1212 and the first positioning hole 1112 cooperate to prevent the stop block 1200 from accidentally protruding from the receiving cavity 1100, keeping the stop block 1200 in the retracted state of the receiving cavity 1100. When the stranding function is not needed, the stop block 1200 can be hidden in the receiving cavity 1100 and protected by the receiving cavity 1100.

[0034] When the operator needs to activate the anti-drift function of the water surface cleaning robot, they can insert their fingers into the finger hole 1240 and pinch the base plate 1230 to apply a pulling force to the stop block 1200 in the direction of the outside of the receiving cavity 1100. The anti-slip strips 1231 on the upper and lower surfaces of the base plate 1230 can prevent the operator's fingers from slipping. At the same time, the operator applies pressure to the pressing plate 1220, causing the protrusions on the pressing plate 1220 to move toward the protrusions 1212 on the elastic sheet 1211. Under the pressure of the pressing plate 1220, the protrusions 1212 on the elastic sheet 1211 dislodge from the first positioning hole 1112, causing the stop block 1200 to gradually move toward the outside of the receiving cavity 1100 along the guide groove 1111. When the stop block 1200 moves to the position of the second positioning hole 1113, the operator stops applying pressure to the pressing plate 1220. Under the action of the elastic sheet 1211's rebound force, the protrusions 1212 are embedded in the second positioning hole 1113, so that the stop block 1200 remains in the state of extending out of the receiving cavity 1100.

[0035] It is understood that in other embodiments not shown, the stop block 1200 may also be installed in the receiving cavity 1100 in other ways, such as a gear structure or a threaded structure, as long as the stop block 1200 can extend or retract into the receiving cavity 1100 and can play a role in preventing it from getting stuck.

[0036] In some embodiments, there are two receiving cavities 1100, which are respectively disposed on the left and right sides of the end of the housing 1000 near the direction of travel.

[0037] In this embodiment, by positioning the receiving cavity 1100 at the end of the housing 1000 near the direction of travel, the stop block 1200 can block the water surface cleaning robot in its direction of travel when it extends out of the receiving cavity 1100. This allows the stop block 1200 to interfere with the pool wall before grounding occurs, preventing the water surface cleaning robot from being washed ashore and more effectively achieving the anti-grounding function. Furthermore, the arrangement of the two receiving cavities 1100 on the left and right sides allows the water surface cleaning robot to achieve anti-grounding function in multiple directions, providing a wider protection range.

[0038] It is understood that in other embodiments, multiple accommodating cavities 1100 may be provided, respectively located on the left and right sides of each end of the housing 1000. Correspondingly, each accommodating cavity 1100 is provided with a stop block 1200. This design enables the water surface cleaning robot to have anti-dwelling function in any direction.

[0039] like Figure 2 and Figure 4 As shown, in some embodiments, a buffer pad 1300 is provided on the end of the housing 1000 near the direction of travel.

[0040] In this embodiment, by installing a buffer pad 1300 on one end of the housing 1000 where the receiving cavity 1100 is provided, when the water surface cleaning robot is swept to the edge of the pool by the water flow during operation, the buffer pad 1300 will be the first to contact the edge of the pool. This design can effectively buffer the impact force suffered by the housing 1000, thereby protecting the water surface cleaning robot, preventing internal parts from being damaged by vibration during impact, and improving the safety performance of the water surface cleaning robot.

[0041] In some embodiments, a controller is provided inside the housing 1000, and a collision sensor is also provided on the housing 1000, which can transmit signals to the controller.

[0042] In some embodiments, a battery is also provided inside the housing 1000, and there is an electrical connection between the battery, the power unit, and the controller.

[0043] In this embodiment, the housing 1000 also includes a controller, a collision sensor, a battery, and a power unit. The controller controls the movement of the entire water surface cleaning robot, the power unit is a propeller installed within the housing 1000, and the battery provides power to the entire robot. Specifically, the collision sensor can be located within the buffer pad 1300. When the water surface cleaning robot comes into contact with the edge of the pool, the collision sensor is triggered and sends a signal to the controller, indicating that the robot is at risk of stranding. The controller then controls the power unit to move the robot away from the pool edge and towards the center of the pool, further reducing the possibility of stranding.

[0044] In some embodiments, a removable trash basket 2000 is also provided inside the housing 1000 for storing trash. In this embodiment, the trash basket 2000 is removably disposed inside the housing 1000 and has a drawer-type design. Rotatable rollers are also provided on the housing 1000 or the trash basket 2000. A power device drives the housing 1000 to move on the water surface. Trash on the water surface is drawn into the trash basket 2000 inside the housing 1000 by the rotation of the rollers. The trash basket 2000 is equipped with a filter screen to filter the trash out of the water, thereby completing the cleaning of trash on the water surface.

[0045] In summary, this application proposes a water surface cleaning robot, including a housing 1000 and a receiving cavity 1100 disposed on the side wall of the housing 1000. By providing a stop block 1200 on the housing 1000 that can extend or retract into the receiving cavity 1100, and by operating the stop block 1200 to extend out of the receiving cavity 1100, when the water surface cleaning robot travels to the edge of the pool, the stop block 1200 will first interfere with the pool wall or other structures at the edge of the pool, thereby preventing the water surface cleaning robot from being washed ashore by the water flow, thus preventing it from getting stranded. This allows the water surface cleaning robot to perform cleaning work stably and continuously, improving reliability.
