Description

Technical Field

[0001] This utility model relates to the field of swimming pool cleaning robot technology, and in particular to a surface swimming pool cleaning robot. Background Technology

[0002] As people's demands for quality of life increase, the cleaning and maintenance of swimming pools have become increasingly important. Traditional manual cleaning methods are inefficient, labor-intensive, and difficult to thoroughly remove small debris from the pool bottom. Therefore, swimming pool cleaning robots have emerged as the mainstream solution for automated cleaning.

[0003] Currently, most swimming pool cleaning robots on the market rely on propeller propulsion systems for autonomous movement. The propellers are driven by motors, generating thrust through rotation to propel the robot across the pool surface. Simultaneously, they work with brushes, suction pumps, or filtration systems to collect debris such as leaves, gravel, and algae. This propulsion method offers advantages such as simple structure, flexible control, and adaptability to different pool shapes.

[0004] However, existing propeller designs have the following technical shortcomings: Fixed propellers are easily jammed by foreign objects: There are often debris such as hair, plastic fragments, and leaves in the pool environment. When the propeller rotates at high speed, it is easy for these foreign objects to get tangled, causing the motor to stall, power to decrease, or even damage the drive system.

[0005] Maintenance difficulties: Once the propeller gets stuck, it usually requires manual disassembly and cleaning, which affects the robot's continuous working ability and increases maintenance costs. Utility Model Content

[0026] Please see Figures 1 to 3 The present invention provides a swimming pool cleaning robot 100, which includes: The body 10 has a cavity 102 inside it, and an opening 101 is formed at one end of the body 10. The opening 101 is connected to the cavity 102. During the movement of the body 10, floating objects on the water surface enter the cavity 102 through the opening 101. Two propellers 20 are disposed at the other end of the opening 101. A drive assembly 30 is disposed inside the body 10. The drive assembly 30 is at least partially exposed outside the body 10. The propellers 20 and the drive assembly 30 are magnetically attracted. When the propellers 20 and the drive assembly 30 are magnetically attracted, the drive assembly 30 is used to drive the propellers 20 to rotate so that the body 10 moves.

[0027] In this embodiment of the invention, the body 10 has a receiving cavity 102, an opening 101 for collecting floating objects, and a drive assembly 30 at the rear end. The drive assembly 30 is partially exposed outside the body 10, and the propeller 20 is connected to the drive assembly 30 by magnetic attraction. In the magnetic attraction state, the drive assembly 30 drives the propeller 20 to rotate and propel it. This structure is simple and easy to implement. Specifically, as the robot moves along the water surface, the front opening 101 guides floating objects into the receiving cavity 102. The drive assembly 30, located at the rear of the body 10, is magnetically connected to the propeller 20 via an exposed shaft. When the drive motor rotates the shaft, the magnetic coupling causes the propeller 20 to rotate synchronously, generating propulsion. When the propeller 20 becomes entangled with foreign objects, the magnetic connection can be directly separated, allowing the propeller 20 to be removed for cleaning without tools. This significantly reduces maintenance costs and improves the user experience.

[0028] This invention effectively solves the problem of difficult propeller maintenance, allowing operators to quickly remove entangled foreign objects without disassembling the entire machine, significantly improving equipment maintenance efficiency. The magnetic connection structure maintains reliable power transmission while avoiding the wear and tear and difficulty in disassembly inherent in traditional connection methods, extending the service life of key components.

[0029] Please see Figure 2 Preferably, the drive component 30 includes: A drive motor (not shown in the figure) is located inside the body 10. A rotating shaft 301 is connected to a drive motor, which drives the rotating shaft 301 to rotate. The propeller 20 is detachably connected to the rotating shaft 301 so that when the drive motor drives the rotating shaft 301 to rotate, it drives the propeller 20 to rotate.

[0030] The drive motor refers to the device that provides rotational power, specifically a brushless DC motor, which is fixed inside the body 10 to drive the rotating shaft 301 to rotate. The rotating shaft 301 is a rigid rod that transmits power, specifically a hollow shaft made of stainless steel, with one end connected to the output of the drive motor and the other end extending to the outside of the body 10. The detachable connection refers to the assembly method that allows the propeller 20 to be separated from the rotating shaft 301, specifically using a snap-fit ​​or threaded interface, allowing the propeller 20 to be removed individually after detaching from the rotating shaft 301. Specifically, the drive motor is installed in the accommodating cavity 102 inside the body 10, and its output end is fixedly connected to the rotating shaft 301 via a coupling. The rotating shaft 301 extends along the length of the body 10, with its end passing through the outer shell of the body 10 and exposed to the external environment. The propeller 20 is fitted onto the end of the rotating shaft 301 through a connecting port and is axially fixed by a snap-fit ​​structure. When the drive motor starts, the rotating shaft 301 drives the propeller 20 to rotate synchronously, thereby generating thrust to move the body 10 on the water surface. When maintenance or cleaning is required, the propeller 20 can be directly pulled out axially without disassembling the drive motor or other internal components.

[0031] Preferably, a first magnetic block (not shown) is formed on the body 10. The first magnetic block is located on one side of the drive assembly 30. The rotating shaft 301 passes through the first magnetic block and is exposed on the body 10. The propeller 20 is magnetically connected to the first magnetic block.

[0032] Specifically, the first magnetic block refers to a magnetic component located near the drive assembly 30 of the fuselage 10. It can be implemented using a permanent magnet or an electromagnet, and achieves quick assembly and disassembly of the propeller 20 and the fuselage 10 by generating a magnetic attraction with the propeller 20. The rotating shaft 301 passing through the first magnetic block means that the rotating shaft 301 passes through the center of the first magnetic block and extends to the outside of the fuselage 10. It can be implemented using a shaft-hole mating structure to ensure that the rotating shaft 301 remains fixed in position with the magnetic block while transmitting power.

[0033] Specifically, when the drive motor drives the propeller 20 to rotate via the rotating shaft 301, the connecting seat 203 of the propeller 20 is magnetically fixed to the first magnetic block on the body 10 through the built-in magnetic material, ensuring the stability of power transmission. When the propeller 20 is entangled with foreign objects, it can be separated from the rotating shaft 301 by applying external force. At this time, the magnetic connection between the first magnetic block and the propeller 20 is released, making it easier to clean or replace the propeller 20. The structural design of the rotating shaft 301 penetrating the first magnetic block ensures that the drive assembly 30 remains completely encapsulated after the propeller 20 is disassembled, thereby preventing water or impurities from entering the body 10 and effectively improving the waterproofness of the water surface pool cleaning robot 100.

[0034] Please see Figure 3 Preferably, the propeller 20 includes: Blade 201; The connecting shaft 202 is fixedly connected to one end of the blade 201, and the blade 201 includes three helical blades. The connecting seat 203 and the connecting shaft 202 are fixedly disposed at the other end of the connecting shaft 202. The connecting shaft 202 is hollow. The connecting seat 203 has a connecting port that communicates with the inside of the connecting shaft 202. The rotating shaft 301 enters the connecting shaft 202 through the connecting port and is detachably connected to the propeller 20.

[0035] In this embodiment, the helical blades refer to a propulsion structure with a curved arc, specifically achieved by molding engineering plastics. The even distribution of three blades creates a stable water flow thrust. The hollow connecting shaft 202 refers to a shaft structure with an internal through-cavity, which can be formed by injection molding or machining. Its inner diameter matches the outer diameter of the rotating shaft 301 for a plug-in fit. The connecting port refers to a through hole on the end face of the connecting seat 203, which can be circular or hexagonal, used to guide the rotating shaft 301 axially into the connecting shaft 202. Specifically, when the drive motor rotates the rotating shaft 301, the rotating shaft 301 is inserted into the hollow connecting shaft 202 through the connecting port, causing the propeller 20 to rotate synchronously with the rotating shaft 301. The three helical blades push the water flow during rotation, generating propulsion to move the machine body 10 on the water surface. The connecting seat 203 and the connecting shaft 202 are integrated, with a gap maintained between the connecting port and the rotating shaft 301 to avoid rotational friction resistance. The structure of the hollow connecting shaft 202 allows the rotating shaft 301 to be directly embedded inside, achieving power transmission without additional fasteners. Disassembly only requires pulling the propeller 20 axially for separation, making the structure simple and easy to implement.

[0036] Preferably, the connecting seat 203 is flat on the side away from the blade 201, and the first magnetic block is flat on the side close to the propeller 20, so that when the propeller 20 is installed in the body 10, the propeller 20 is tightly connected to the body 10.

[0037] In this embodiment, the flattened design of the side of the connector 203 away from the propeller 201 means that the end face of the connector 203 in contact with the body 10 is a planar structure. Specifically, this can be achieved by injection molding to create a flat end face, thus forming a gapless contact surface when the connector 203 contacts the body 10. Similarly, the flattened design of the side of the first magnetic block near the propeller 20 means that the surface of the magnetic block in contact with the connector 203 is a planar structure. This can be achieved by embedding the magnetic block into the outer shell of the body 10 and polishing the surface to a flatness. This design creates a stable magnetic contact area between the magnetic block and the connector 203, thereby improving the magnetic attraction stability between the propeller 20 and the body 10.

[0038] Preferably, a second magnetic block (not shown) is provided inside the connecting seat 203. The first magnetic block and the second magnetic block have different magnetic properties, and the propeller 20 and the body 10 are magnetically attracted through the first magnetic block and the second magnetic block.

[0039] By incorporating a second magnetic block inside the connecting seat 203 of the propeller 20, when the propeller 20 approaches the fuselage 10, the second magnetic block and the first magnetic block on the fuselage 10 generate a magnetic attraction due to their opposite polarities, allowing the propeller 20 to quickly align and be fixed to the fuselage 10. After the rotating shaft 301 of the drive assembly 30 is inserted into the hollow connecting shaft 202 of the connecting seat 203, the propeller 20 rotates synchronously with the rotating shaft 301. When it is necessary to disassemble the propeller 20, only external force needs to be applied to overcome the magnetic attraction to separate the propeller 20 from the fuselage 10, without the need for tools or complex operations.

[0040] Please see Figure 2Preferably, the water surface pool cleaning robot 100 includes a blocking part 40, which is located near the propeller 20 and is used to protect the propeller 20. The blocking part 40 is arranged around the propeller 20.

[0041] The blocking part 40 provides protection around the propeller 20. This can be achieved using a ring-shaped shield or a grid structure, which physically isolates foreign objects from entering the rotation area of ​​the propeller 20. The vicinity of the propeller 20 refers to the space within 5-10 centimeters of its outer edge. This distance can be determined by measuring the maximum outer diameter of the propeller 20's rotation trajectory. This range effectively avoids interference between the blocking part 40 and the propeller 20 while also covering the potential contact area for foreign objects.

[0042] Furthermore, when the pool cleaning robot 100 is moving, the thrust generated by the high-speed rotation of the propeller 20 propels the body 10 to move. At this time, the annular blocking part 40 surrounding the propeller 20 allows water to flow through through its grid structure, but prevents floating objects such as leaves and plastic fragments from contacting the propeller blades 201. When a larger foreign object approaches, the arc-shaped guide surface at the edge of the annular blocking part 40 can guide it to the outside of the annular blocking part 40. The annular blocking part 40 can be connected to the body 10 via a snap-fit ​​structure, and the cover can be directly removed for maintenance when entangled objects need to be cleaned, making operation convenient.

[0043] Please see Figure 1 and Figure 2 Preferably, the water surface pool cleaning robot 100 also includes a garbage bin 50, which is disposed in the receiving cavity 102 and is detachably connected to the body 10.

[0044] Specifically, the waste bin 50 is installed within a cavity 102 formed inside the main body 10, with its opening 101 oriented in the same direction as the direction of travel of the main body 10. As the robot moves along the water surface, floating debris enters the cavity 102 through the opening 101 at the front of the main body 10 and is collected in the waste bin 50. A filter screen at the bottom of the waste bin 50 allows water to pass through but blocks solid debris, thus achieving convenient and quick waste collection.

[0045] Please see Figure 1 Preferably, the pool cleaning robot 100 also includes a roller brush 60 located at the opening 101, which rotates to suck up floating debris from the water surface into the waste bin 50.

[0046] In this embodiment of the invention, the roller brush 60 refers to a rotating cleaning component installed at the opening 101. Specifically, it can be implemented by distributing rigid rotating blades on the surface of a cylindrical brush body. By rotating and contacting the water surface, it sweeps floating debris into the receiving cavity 102. The mechanical force generated by the rotation of the roller brush 60 can disrupt the surface tension of the water, making it easier for fine impurities attached to the water surface to be sucked into the debris bin 50, thereby solving the defect that the traditional propeller 20 propulsion system cannot effectively handle attached impurities. As the robot moves, the roller brush 60 rotates and contacts the water surface, lifting and guiding floating debris toward the opening 101. The debris, carried by the water flow, enters the receiving cavity 102 and is intercepted and collected by the waste bin 50. The continuous rotation of the roller brush 60 not only actively cleans the water surface but also mechanically disperses accumulated impurities, preventing blockage of the opening 101. Because the roller brush 60 directly acts on the water surface impurity collection stage, it reduces reliance on the propeller 20 propulsion system, thereby reducing the risk of the propeller 20 becoming entangled in foreign objects.

[0047] In the water surface and swimming pool cleaning robot 100 provided by this utility model, the connection structure between the drive component 30 and the propeller 20 is formed by the magnetic detachable propeller 20 structure, which facilitates quick disassembly and maintenance. This solves the problem of easy jamming and difficult maintenance of traditional fixed propellers 20, and has the advantages of convenient propeller maintenance and stable power transmission.
