Description

Technical Field

[0001] This application relates to the field of swimming pool cleaning equipment technology, and more particularly to a water surface cleaning machine. Background Technology

[0002] As people's requirements for swimming pool water quality increase, keeping the pool surface clean has become particularly important. However, in outdoor pools, debris such as fallen leaves, branches, and flowers easily drift onto the water surface. If not cleaned up in time, this not only affects the aesthetics but may also clog the filtration system, affecting the normal use of the pool.

[0003] Existing water surface cleaning machines typically employ gear-driven mechanisms, with a motor-driven roller brush assembly rotating to guide surface debris into a collection basket. The roller brush assembly generally uses rigid plastic blades, which effectively pick up floating debris during rotation, smoothly collecting it into the collection bin. This cleaning method offers greater automation compared to manual retrieval, enabling continuous surface cleaning and improving the convenience of pool maintenance.

[0004] However, current water surface cleaning machines still have many shortcomings in terms of motor waterproofing. First, while the gear transmission mechanism can effectively drive the roller brush assembly, its complex structure increases the risk of the motor coming into contact with water. If the seal is not tight, moisture may seep into the motor along the drive shaft, causing short circuits or corrosion. Second, existing equipment uses a sealing ring on the drive shaft to protect the motor. This type of sealing on a moving part, like a sealing ring around the motor shaft, is a dynamic seal. Due to the high-speed rotation of the motor shaft and the friction between the sealing ring and the motor shaft, the sealing ring has a high probability of failure, increasing the risk of moisture penetration. Therefore, a roller brush structure for water surface cleaning machines that can better prevent moisture penetration into the motor is needed to solve the above problems. Utility Model Content

[0005] In view of this, it is necessary to provide a water surface cleaning machine that can better prevent water vapor from penetrating into the motor in order to solve the above problems.

[0006] An embodiment of this application provides a water surface cleaning machine, comprising:

[0015] In at least one embodiment of this application, the sealing shell includes a partition and a first shell and a second shell respectively disposed on both sides of the partition, wherein the first shell and the partition form a first cavity, and the second shell and the partition form a second cavity;

[0016] The motor is located in the first cavity and partially extends into the second cavity, and the first magnetic ring is located in the second cavity.

[0017] In at least one embodiment of this application, the partition is provided with a first sealing groove and a second sealing groove on opposite sides in an annular shape;

[0019] In at least one embodiment of this application, the first housing includes a body and a locking portion integrally formed with the body, wherein the locking portion is formed by extending outward from the side of the first housing near the partition, and the locking portion engages with the partition.

[0020] The drive assembly further includes a fixing member, which is respectively inserted through the first part, the partition part and the second part, for fixing the first part, the partition part and the second part.

[0021] In at least one embodiment of this application, the roller brush assembly includes a roller brush cylinder and a flexible roller brush sheet circumferentially disposed on the roller brush cylinder, and the second driving member is fixedly connected to the roller brush cylinder.

[0022] The roller brush cylinder includes a cylinder body and an end cap. The cylinder body has a fixing groove circumferentially formed along its length.

The first drive component is completely sealed within a sealed housing, while the second drive component rotates solely under magnetic force. This completely avoids the friction and wear problems between the traditional transmission shaft and the sealing ring, fundamentally solving the risk of water vapor seeping into the motor due to dynamic seal failure, and significantly improving the motor's waterproof reliability and service life. The complex gear transmission structure of existing technologies is replaced by magnetic drive, and there are no mechanical connecting parts between the sealed housing and the outer shell. Only static sealing of the sealed housing is required to achieve complete isolation between the motor and the external water environment. Attached Figure Description

Detailed Implementation

[0041] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0042] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component.

[0043] An embodiment of this application provides a water surface cleaning machine, comprising:

[0044] The body includes an outer shell and a sealed shell disposed within the outer shell and isolated from the outside;

[0045] The drive assembly includes a first drive member and a second drive member, wherein the first drive member is disposed inside the sealed housing, the second drive member is located inside the outer housing and outside the sealed housing, and the first drive member and the second drive member are magnetically connected.

[0046] A roller brush assembly is disposed on the second driving member and is used to rotate with the second driving member when the first driving member is running.

[0047] The aforementioned water surface cleaning machine completely eliminates the need for a transmission shaft and dynamic seal structure required by traditional gear transmissions by using magnetic drive for both the first and second drive components. The first drive component is completely sealed within a sealed housing, while the second drive component rotates solely under magnetic force. This completely avoids the friction and wear problems between the traditional transmission shaft and the sealing ring, fundamentally solving the risk of water vapor seeping into the motor due to dynamic seal failure, and significantly improving the motor's waterproof reliability and service life. The complex gear transmission structure of existing technologies is replaced by magnetic drive, and there are no mechanical connecting parts between the sealed housing and the outer shell. Only static sealing of the sealed housing is required to achieve complete isolation between the motor and the external water environment.

[0048] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Please see Figures 1-13 The embodiments of this application provide a water surface cleaning machine 100, including a body 10, a drive assembly 20 and a roller brush assembly 30.

[0050] The body 10 includes an outer shell 11 and a sealed shell 12 disposed inside the outer shell 11 and isolated from the outside; the drive assembly 20 includes a first drive member 21 and a second drive member 22, the first drive member 21 is disposed inside the sealed shell 12, the second drive member 22 is located inside the outer shell 11 and outside the sealed shell 12, and the first drive member 21 and the second drive member 22 are magnetically connected; the roller brush assembly 30 is disposed on the second drive member 22 and is used to rotate with the second drive member 22 when the first drive member 21 is running.

[0051] Specifically, the outer casing 11 serves as the external protective structure of the water surface cleaning machine, providing support and protection to prevent external debris from directly contacting the internal components. The sealed casing 12, located inside the outer casing 11, is completely isolated from the external environment, housing the first drive component 21 and ensuring it remains in a dry, sealed environment to prevent moisture or liquid ingress. Through the design of the sealed casing 12, the motor 211 is completely isolated from the external water environment, fundamentally solving problems such as short circuits and corrosion caused by water ingress into the motor 211 in traditional water surface cleaning machines, significantly improving the equipment's waterproof performance and reliability.

[0052] Furthermore, the second drive component 22 is located outside the sealing shell 12 and is magnetically connected to the first drive component 21, transmitting power to the roller brush assembly 30. Magnetic coupling enables non-contact power transmission, avoiding the shaft sealing problems inherent in traditional mechanical transmissions. The magnetic drive method eliminates the need for mechanical contact, completely eradicating the friction and wear problems between the traditional drive shaft and the sealing ring, reducing maintenance costs and extending equipment lifespan. Non-contact transmission also prevents moisture from seeping into the motor 211 along the drive shaft, further enhancing waterproofing performance.

[0053] In one specific embodiment, the first driving member 21 includes a motor 211 disposed in the sealing shell 12 and a first magnetic ring 212 that is drivenly connected to the motor 211, and the first magnetic ring 212 is connected to the bearing of the sealing shell 12;

[0054] The second driving member 22 includes a second magnetic ring 221, the central axes of the first magnetic ring 212 and the second magnetic ring 221 are located on the same straight line, and there is a gap 23 between the second magnetic ring 221 and the sealing shell 12.

[0055] Specifically, the first magnetic ring 212 is supported by bearings, enabling it to rotate smoothly while reducing friction and improving transmission efficiency. The bearings reduce rotational resistance, making magnetic transmission smoother and more efficient. The bearing support structure prevents wear caused by magnetic ring misalignment, improving the durability of the device. The second magnetic ring 221, as an external driving component, forms a magnetic coupling with the first magnetic ring 212, achieving contactless power transmission.

[0056] Furthermore, ensuring the magnetic coupling direction of the two magnetic rings remains consistent guarantees stable and efficient torque transmission. This maximizes magnetic force transmission efficiency and minimizes energy loss. The coaxial arrangement ensures uniform distribution of magnetic coupling force, reducing vibration or transmission instability caused by misalignment. A gap 23 isolates the first magnetic ring 212 and the second magnetic ring 221, preventing physical contact friction while allowing magnetic force transmission. When the external roller brush is jammed by foreign objects, the torque transmitted between the magnetic rings is insufficient to clear the objects, causing the second magnetic ring 221 to stop rotating, while the motor 211 can continue rotating, preventing the motor 211 from stalling and burning out.

[0057] In one specific embodiment, the first magnetic ring 212 includes a first support member 212a and a plurality of first magnets 212b arranged around the first support member 212a, and a first partition portion 212c is provided between two adjacent first magnets 212b;

[0058] The second magnetic ring 221 includes a second support member 221a and a plurality of second magnets 221b arranged around the second support member 221a. A second separation portion 221c is provided between two adjacent second magnets 221b. Each first magnet 212b is directly opposite to each second magnet 221b, and the magnetic poles of the first magnet 212b and the second magnet 221b are opposite.

[0059] Specifically, the first support 212a serves as a fixed base for the magnets, ensuring that the magnets are neatly arranged and stably supported. The first magnets 212b are arranged in a ring to ensure a uniform magnetic field distribution and enhance the stability of magnetic coupling. This improves magnetic field uniformity, reduces magnetic loss, and increases transmission efficiency. The support fixes the magnets, preventing them from loosening or shifting due to vibration or external force, thus improving system reliability. The first separator 212c is used to isolate adjacent magnets, preventing mutual interference of magnetic fields.

[0060] Furthermore, the second magnetic ring 221 has a similar structure to the first magnetic ring 212. Its support member fixes the second magnet 221b and forms magnetic coupling with the first magnetic ring 212. Due to the magnetic coupling, when the first magnetic ring 212 rotates, the second magnetic ring 221 rotates synchronously, achieving contactless transmission. Through the attraction of opposite magnetic poles, a stable magnetic coupling is formed, achieving efficient torque transmission. Each first magnet 212b is directly opposite each second magnet 221b, ensuring that the magnets on the first magnetic ring 212 and the second magnetic ring 221 are strictly aligned, so that the magnetic fields can interact to the maximum extent, achieving efficient magnetic coupling transmission.

[0061] In one specific embodiment, each of the first magnets 212b includes a positive pole portion and a negative pole portion, and a plurality of the first magnets 212b are arranged alternately along the positive pole portion and the negative pole portion facing the side of the second magnet 221b.

[0062] Specifically, the magnets on the first magnetic ring 212 are arranged in an alternating structure, meaning the positive and negative poles of adjacent magnets are alternately arranged to form a stable alternating magnetic field. This alternating arrangement makes the magnetic field distribution more uniform, reduces magnetic field disturbance, and improves the stability of magnetic coupling. The alternating arrangement also reduces the unevenness caused by the magnetic field concentrating on one side, improving magnetic field alignment and thus enhancing magnetic force transmission capability.

[0063] In another specific embodiment, both the first magnetic ring 212 and the second magnetic ring 221 are complete magnetic rings. By alternately filling different magnetic poles onto the magnetic rings, the effect of multiple magnets being arranged in an alternating manner is achieved. The directional magnetization process used in the manufacturing process is existing technology and will not be described in detail here. The magnetic poles of the first magnetic ring 212 and the second magnetic ring 221 correspond to each other, improving the magnetic coupling effect.

[0064] In one specific embodiment, the sealing shell 12 includes a partition 123 and a first shell 121 and a second shell 122 respectively disposed on both sides of the partition 123. The first shell 121 and the partition 123 enclose a first cavity 124, and the second shell 122 and the partition 123 enclose a second cavity 125.

[0065] The motor 211 is located inside the first cavity 124 and partially extends into the second cavity 125, and the first magnetic ring 212 is located inside the second cavity 125.

[0066] Specifically, the sealing shell 12 consists of a partition 123, a first shell 121, and a second shell 122, forming an independent cavity structure. The partition 123 provides structural support and also creates physical isolation between the first cavity 124 and the second cavity 125, preventing mutual interference. The partition 123 divides the sealing shell 12 into two cavities, rationally allocating internal space and facilitating the installation and maintenance of the motor 211 and the magnetic ring. As the core support structure of the sealing shell, the partition 123 provides a stable assembly reference surface for the first shell 121 and the second shell 122. This ensures accurate positioning of each component during assembly, reducing sealing failure or performance degradation caused by misalignment. It also reduces assembly difficulty and improves production efficiency.

[0067] Furthermore, the drive shaft of the motor 211 extends through the partition 123 into the second cavity 125 and connects with the first magnetic ring 212 to achieve power transmission. The first magnetic ring 212 is located in the second cavity 125 and is coupled to the second magnetic ring 221 through magnetic force, driving the roller brush assembly 30 to rotate. The direct connection between the motor 211 and the first magnetic ring 212 ensures the accuracy and stability of power transmission. The motor 211 only partially extends into the second cavity 125, and the second cavity 125 is isolated from the external environment, reducing the possibility of moisture seeping into the motor 211.

[0068] In one specific embodiment, the partition 123 is provided with a first sealing groove 123a and a second sealing groove 123b respectively on opposite sides;

[0069] The drive assembly 20 further includes a seal 24, which is respectively disposed in the first sealing groove 123a and the second sealing groove 123b. The first housing 121 extends into the first sealing groove 123a and is interference-fitted with the seal 24, and the second housing 122 extends into the second sealing groove 123b and is interference-fitted with the seal 24.

[0070] Specifically, a first sealing groove 123a and a second sealing groove 123b are respectively provided on both sides of the partition 123 for installing the sealing element 24 to form an effective sealing structure. The sealing grooves are distributed in a ring shape, which allows the sealing element 24 to fit evenly, achieving 360° all-round sealing and improving the sealing effect. The ring design can reduce local stress concentration, extend the service life of the sealing element 24, and prevent the risk of leakage caused by uneven local stress.

[0071] Furthermore, sealing grooves 123a and 123b are respectively provided on both sides of the partition 123, forming two sealing interfaces. The function of the sealing grooves is to accommodate the sealing element, providing an effective sealing barrier to prevent moisture, dust, or debris from entering the drive system and avoiding damage or malfunction due to external environmental influences. The sealing element 24 is a key component used to fill the sealing grooves and has an interference fit with the housing. The sealing element 24 is typically made of a material with good elasticity (such as rubber, silicone, etc.), which can effectively prevent liquid leakage and ensure its normal operation.

[0072] In one specific embodiment, the first housing 121 includes a body 121a and a locking portion 121b integrally formed with the body 121a. The locking portion 121b is formed by extending outward from the side of the first housing 121 near the partition 123, and the locking portion 121b locks into the partition 123.

[0073] The drive assembly 20 further includes a fixing member 25, which is respectively disposed in the first housing 121, the partition 123 and the second housing 122, for fixing the first housing 121, the partition 123 and the second housing 122.

[0074] Specifically, the engaging part 121b enhances the connection between the housing and the partition 123 through physical engaging force, preventing components from loosening due to equipment vibration or external forces, thereby ensuring the structural stability of the equipment. The design of the engaging part 121b greatly simplifies the assembly process, eliminating the need for complex connectors or tools, and reducing processing and assembly time costs.

[0075] Furthermore, the design of the engaging portion 121b allows the first housing 121 and the partition 123 to be pre-fixed during assembly. This means that before the fastener 25 is installed, the engaging portion 121b ensures a preliminary connection between the two components, preventing relative displacement or misalignment during assembly. The fastener 25 is designed to quickly and accurately fix the three components into a single unit by passing through the first housing 121, the partition 123, and the second housing 122. This design reduces potential errors during disassembly and assembly, while making the entire assembly process more efficient.

[0076] Furthermore, by installing the fastener 25, the connection between the first housing 121, the partition 123, and the second housing 122 is ensured to be stable, thereby significantly improving the overall integrity and sealing performance of the equipment. The seal 24 is also well supported and fixed in this process, further enhancing its waterproof and dustproof sealing performance.

[0077] In one specific embodiment, the roller brush assembly 30 includes a roller brush cylinder 31 and a flexible roller brush 32 circumferentially disposed on the roller brush cylinder 31, and the second driving member 22 is fixedly connected to the roller brush cylinder 31;

[0078] The roller brush cylinder 31 includes a cylinder body 311 and an end cap 312. The cylinder body 311 has a fixing groove 313 circumferentially formed along its length. The end cap 312 covers both ends of the cylinder body 311 to enclose both ends of each fixing groove 313. The flexible roller brush 32 is disposed in the fixing groove 313.

[0079] Specifically, the roller brush cylinder 31 is the core component of the roller brush assembly 30, responsible for supporting and fixing the roller brush blades and transmitting power from the second drive member 22. Flexible roller brush blades 32 are arranged around the roller brush cylinder 31. These roller brush blades can flexibly follow surface changes and prevent the hard roller brush blades from getting stuck when they encounter large and hard debris.

[0080] In one specific embodiment, the flexible roller brush 32 is made of flexible silicone.

[0081] Furthermore, the cylinder 311 has a fixing groove 313 circumferentially formed along its length to provide a fixed mounting position for the flexible roller brush 32. This ensures that the roller brush is firmly fixed to the roller brush cylinder 31, preventing it from sliding or falling off during use. End caps 312 are respectively placed on both ends of the cylinder 311 to enclose the ends of each fixing groove 313. This design ensures the stability of the roller brush and prevents it from loosening or falling off due to external forces during operation. Through the structural design of the fixing grooves 313 and end caps 312, the roller brush can be installed more precisely, enhancing the stability and reliability of the entire roller brush assembly 30.

[0082] In one specific embodiment, the fixing groove 313 is convex in shape. The end cap 312 restricts the degree of freedom of the flexible blade in the length direction of the roller brush cylinder 31. The edge of the convex shape abuts against the flexible roller brush blade. The connection end of the flexible roller brush blade and the roller brush cylinder 31 corresponds to the shape of the fixing groove 313. The degree of freedom of the blade is restricted in the direction perpendicular to the axis of the roller brush cylinder 31.

[0083] In one specific embodiment, the cleaning machine further includes a storage compartment 40, which is slidably connected to the outer casing 11. The roller brush assembly 30 is disposed on the storage compartment 40 and partially extends out of the side wall of the storage compartment 40. Both ends of the roller brush assembly 30 are connected to the side wall bearings of the storage compartment 40.

[0084] Specifically, the storage compartment 40, through a sliding connection with the outer casing 11, can be easily extended or retracted from the outside of the device when needed. The bearing connection between the roller brush assembly 30 and the two ends of the storage compartment 40 effectively improves its stability and reliability. This design ensures stable operation of the roller brush during cleaning, while preventing debris from being pushed haphazardly, thus ensuring cleaning effectiveness. The bearing connection also reduces friction and wear during transmission, extending its service life and further guaranteeing the stability of the magnetic connection between the drive components 20.

[0085] In one specific embodiment, the storage compartment 40 further includes a storage section 41 and a stop section 42. The roller brush assembly 30 is disposed on the storage section 41, and the stop section 42 is disposed at one end of the storage section 41 near the roller brush assembly 30 to prevent debris from entering the shaft connection between the roller brush assembly 30 and the storage section 41.

[0086] Specifically, the receiving section 41 is used to hold debris or garbage swept by the roller brush assembly 30. The roller brush assembly 30 is fixed to the receiving section 41 to ensure that garbage can be effectively guided into the receiving compartment 40 during the cleaning process. The stop section 42 is provided at one end of the receiving section 41 near the roller brush assembly 30, which can effectively prevent debris from getting stuck or clogging the shaft connection between the roller brush assembly 30 and the receiving section 41, thereby reducing mechanical failures or operational problems caused by debris entering the bearing area and extending the service life of the equipment.

[0087] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
