[0002] With the development of intelligent hardware technology, intelligent cleaning devices have been widely used in various fields of production and life, and swimming pool robots are one of them. Pool robots can work underwater for a long time and are used to clean the bottom and side walls of the swimming pool. However, due to the limitation of battery pack capacity, swimming pool robots need to be charged regularly. There are two main charging methods in the existing technology. One is to directly take the swimming pool robot out of the swimming pool and charge it on land. The defect of this charging method is that the operation process is cumbersome and the user's labor is large; the second is to set a charging base station at the bottom of the swimming pool. When the power of the swimming pool robot is low, it can automatically track to the base station for charging. The defect of this charging method is that the underwater return to the charging base station is easily blocked, and it is difficult for the swimming pool robot to effectively enter the charging position. In addition, the base station is immersed in water for a long time, and there are risks such as leakage and short circuit. Utility Model Content

DETAILED DESCRIPTION

[0047] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0048] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0049] A pool robot is an intelligent cleaning device used to clean and maintain swimming pools. Its main structure includes the following parts: Host, the main control unit of the pool robot, including motors, batteries, sensors and control systems, etc. Sewage suction structure, pool robots are usually equipped with a sewage suction structure, which can help clean dirt and debris on the bottom and edge of the pool. Filter system, the filtration system of the pool robot is mainly used to filter impurities and particles in the pool water to keep the water clean. Roller brush, some pool robots are also equipped with a roller brush to clean dirt and stains on the walls and floors of the swimming pool.

[0050] The pool robot uses built-in sensors and navigation systems to determine the cleaning path and ensure that the entire bottom and edges of the pool are covered. In addition, the pool robot collects dirt and debris through the suction structure and filters it into the built-in filtration system. The filtration system can use different types of filters as needed, such as cloth bags or mesh filters. If the pool robot is equipped with a roller brush, it will use the roller brush to remove stains and dirt from the pool walls and floor during the cleaning process.

[0051] The application scenarios of pool robots are very wide. For example, pool robots can help clean and maintain home swimming pools and reduce the workload of manual cleaning. For public swimming pools, pool robots can clean regularly to improve water quality and hygiene. In addition, in the swimming pools of large hotels and resorts, pool robots can efficiently clean large areas of pool water and ensure the hygiene and safety of the swimming pool. In general, pool robots can improve the cleanliness and water quality of swimming pools, reduce the workload of manual cleaning, and create a better swimming experience for users.

[0052] The pool robot is generally provided with the power required for movement by the battery pack it carries. After using it for a period of time, the pool robot needs to be charged. There are generally two ways to charge the pool robot: manual charging and automatic charging. Manual charging requires the user to connect the pool robot to a charger or charging station, and then connect the power supply through the power cord to charge the pool robot. The disadvantage of manual charging is that the user needs to connect it personally, which is troublesome to operate, and also increases the risk of use and the complexity of manual operation. Automatic charging uses an automatic charging station for charging. The pool robot can find the automatic charging station by itself, and autonomously align and contact the charging station to realize the automatic charging process. The advantage of automatic charging is that it simplifies the user's operation, allowing the pool robot to charge autonomously, and also reduces the risk of use. However, this charging base station in the prior art is generally set underwater. Since the return to the charging base station underwater is easily blocked, it is difficult for the pool robot to effectively enter the charging position, and the base station is immersed in water for a long time, there are risks such as leakage and short circuit.

[0053] Of course, in addition to manual and automatic charging methods, some pool robots use solar charging, wireless charging and other technologies to achieve charging, but these technologies also have some disadvantages: solar charging requires the pool robot to have solar panels, and it needs to be charged in a sunny environment. Bad weather will affect the charging efficiency, and solar charging is not possible at night. Wireless charging requires that the distance between the pool robot and the charging station should not be too far. If the distance is too far, it will affect the charging efficiency, and it may also be affected by external interference and cause charging failure. In general, the current charging methods of pool robots have problems such as narrow applicability, low charging efficiency, and affected safety. Continuous technological innovation and breakthroughs are needed to meet a wider range of needs.

[0054] In view of the above problems, the utility model provides a charging device, which realizes a reliable electrical connection between the underwater swimming pool robot and the charging base station on the water surface through a transfer device floating on the water surface, thereby solving the problems of the prior art such as complicated charging process, difficult coupling of charging interface, and poor safety.

[0055] The technical solution of the utility model is described in detail below in conjunction with specific embodiments:

[0056] See also Figure 1-9 As shown, the embodiment of the utility model provides a charging system for a swimming pool robot, which includes a main body of a swimming pool robot 20, a charging device connected to the swimming pool robot 20 through a cable 12, and a base station 30 arranged at the side of the swimming pool for adapting the charging device. Of course, the base station 30 can also be arranged floating on the water surface, and the specific installation position of the base station 30 can be selected according to user needs. In addition, the base station 30 can be connected to the mains through an adapter, or the base station 30 itself can also be a power source, and the swimming pool robot can be charged directly through the charging device without connecting to the mains.

[0057] See also Figure 1 As shown, in a specific embodiment, the swimming pool robot 20 includes a body, and a walking mechanism, a cleaning mechanism and a battery pack installed on the body. The walking mechanism may include, for example, track wheels or traditional round wheels. In a further embodiment, in order to adapt to the wall climbing action of the swimming pool robot 20, the front and rear ends of the housing of the swimming pool robot 20 do not exceed the front and rear ends of the walking mechanism, so that the front and rear ends of the walking mechanism can contact the wall.

[0058] In addition, in the pool robot 20 equipped with the wall climbing function, a water spraying device can also be provided, which can suck the water near the pool robot 20 into the pool robot 20, and then discharge the water from the top of the pool robot 20, so that a reaction force toward the side wall of the pool can be generated for the pool robot 20, so that the pool robot 20 can be close to the side wall of the pool to achieve the wall climbing function; it should be understood that when the pool robot 20 walks on the bottom wall of the pool, the water spraying device can also be turned on to increase the adhesion between the pool robot 20 and the bottom wall to prevent the pool robot 20 from slipping. The battery pack is accommodated in the body and is used to power the walking mechanism and the cleaning mechanism. There is no special limitation on the specific type of the battery pack, for example, it can be a lithium-ion battery (Li-ion), a nickel-metal hydride battery (NiMH), a lead-acid battery (Lead-acid), etc. It is preferred to use a lithium-ion battery, which is one of the most commonly used rechargeable batteries at present, and has the advantages of high energy density, long service life and low self-discharge rate. They can be designed into different shapes and sizes to meet the needs of various pool robots 20.

[0059] It should be understood that the present invention is mainly an improvement on the charging device of the swimming pool robot 20, so the specific transmission structure and working principle of the walking mechanism and cleaning mechanism of the swimming pool robot 20 will not be described in detail. The charging device of the swimming pool robot 20 will be described in detail below.

[0060] See also Figure 1 , 2 As shown, the charging device provided by the embodiment of the present invention includes a carrier 10 , a first charging unit 11 and a cable 12 .

[0062] It should be understood that the material of the carrier 10 is not unique, and any material or structure that can float on the water surface should be applicable to the present invention; for example, in some other embodiments, the carrier 10 may also be a shell-like structure, such as a shell-like structure with a cavity made of lightweight materials such as plastic and fiberglass; for another example, the carrier 10 may also be an airbag made of a flexible material, and the airbag is filled with a safety gas, which may be, for example, air, carbon dioxide, nitrogen, helium, argon, etc.

[0063] See also Figure 1 , 6 As shown in FIG. 7 , the first charging unit 11 is installed on the carrier 10. It should be understood that the first charging unit 11 is a power receiving device. In a specific embodiment, the first charging unit 11 can be, for example, Figure 2 The wireless charging receiving module shown, correspondingly, the base station 30 can be provided with a second charging unit 31 matching the first charging unit 11, and the second charging unit 31 can be, for example, a wireless charging transmitting module.

[0064] The wireless charging receiving module may include, for example, an antenna, a rectifier circuit, a power management circuit, a control circuit, and a housing; the wireless charging receiving module includes an antenna for receiving electromagnetic wave signals emitted by the wireless charger. The antenna may be made of a conductor coil or a wire, and its shape and size are designed according to the technical standards and requirements of wireless charging. The received wireless energy is generally an AC electromagnetic wave signal, which needs to be converted into DC power by a rectifier circuit for use by subsequent circuits. The rectifier circuit may be composed of components such as diodes, which can convert AC signals into DC signals. The wireless charging receiving module may use a power management circuit to manage and optimize the received energy. These circuits may include power regulators, current and voltage monitoring circuits, etc., for controlling energy conversion and providing appropriate power output. The wireless charging receiving module may also include a control circuit for controlling the receiving and conversion process. The control circuit can be used to monitor charging efficiency, protect the battery, provide charging status indication, and other functions. The wireless charging receiving module may include a housing for protecting internal circuits and components and providing mechanical support and connection interfaces. The housing may be made of plastic, metal, or other suitable materials.

[0065] The wireless charging transmitter module may include, for example, a transmitting coil, a driving circuit, a tuning circuit, a control circuit, and a housing; the wireless charging transmitter module includes a transmitting coil for generating an electromagnetic field to transmit electrical energy. The transmitting coil may be made of a conductor coil or a wire, and its shape and size are designed according to the technical standards and requirements of wireless charging. The transmitting coil requires a driving circuit to provide current and frequency to generate an appropriate electromagnetic field. The driving circuit may be composed of a power supply, a power amplifier, and a frequency control circuit, etc., which can convert and adjust the input electrical energy into a form suitable for transmission. In order to improve the efficiency of wireless charging, the transmitting module may also include a tuning circuit for matching the resonant frequency between the transmitting coil and the receiving device. The tuning circuit may be composed of a capacitor, an inductor, and a switch, which can adjust the electromagnetic field of the transmitting module to maximize the energy transmission. The wireless charging transmitter module may also include a control circuit for realizing the control of the transmission and transmission process. The control circuit can be used to monitor the charging efficiency, adjust the output power, provide charging status indication, and other functions. The wireless charging transmitter module usually includes a housing to protect the internal circuits and components and provide mechanical support and connection interfaces. The housing is usually made of plastic, metal or other suitable materials.

[0066] The specific types of the first charging unit 11 and the second charging unit 31 in the present invention are not unique. For example, in some other embodiments, one of the first charging unit 11 and the second charging unit 31 may be a waterproof plug, and the other may be a waterproof socket.

[0067] The waterproof plug may include, for example, a shell, a conductor, an insulating layer, a sealing ring or an O-ring and a contactor; the shell of the waterproof plug may be made of water-resistant and corrosion-resistant materials, such as polyvinyl chloride (PVC) or acrylic (PA). The shell will have a waterproof sealing design to ensure that the electrical contact part will not be penetrated by water. The waterproof plug contains a metal conductor inside for transmitting electrical signals or electricity. The conductor can be made of high-quality copper or aluminum to ensure good electrical conductivity. There will be an insulating layer on the surface of the conductor of the waterproof plug, which can be made of polyethylene (PE), polypropylene (PP) or silicone. The insulating layer can provide insulation and sealing between the conductors inside the cable to prevent leakage. The connection part of the waterproof plug can be provided with a sealing ring or an O-ring to provide a waterproof effect. The sealing ring can be made of rubber or silicone material, which can well seal the connection point between the plug and the socket. Contactor: The contactor inside the waterproof plug is responsible for the transmission and connection of current. The contactor is usually a sturdy and durable metal material, such as copper, copper alloy, etc.

[0068] The waterproof socket may include, for example, a housing, a slot (interface), a sealing ring or an O-ring, a terminal, a wire protection pipe or a wire seal. The housing of the waterproof socket may be made of a water-resistant and corrosion-resistant material, such as polyvinyl chloride (PVC) or acrylic (PA). The housing has dustproof and waterproof functions through special design and processing. The waterproof socket provides a location for electrical equipment to be inserted or connected. The slot may be composed of an internal electrical connector and an external metal contact. The slot may be made of high-quality conductive metal and have good corrosion resistance.

The waterproof socket has a terminal for connecting the power cord inside, which is used to connect to an external power source. Wire protection pipe or wire seal: The wire outlet of the waterproof socket usually has a wire protection pipe or wire seal to protect the wire at the joint to prevent moisture from invading the inside of the wire.

[0069] Please refer to 1, 6, and 7. One end of the cable 12 is electrically connected to the first charging unit 11, and the other end is electrically connected to the battery pack of the swimming pool robot 20. The cable 12 is used to transmit electrical energy between the first charging unit 11 and the battery pack. In some other more complex application scenarios, a signal transmission line can also be set in the cable 12 for communication between the carrier 10 and the swimming pool robot 20. For example, a signal transceiver module can be set on the carrier 10, and the signal transceiver module is electrically connected to the controller of the swimming pool robot 20 through the cable 12. In this way, the carrier 10 is used as a communication antenna of the swimming pool robot 20 to facilitate the communication between the swimming pool robot 20 and the external terminal device, thereby solving the problem of low propagation efficiency of communication signals in water.

[0070] In a specific embodiment, the cable 12 can be a waterproof cable suitable for underwater environment. The cable 12 can include, for example, an outer skin, an insulating layer, a shielding layer, an inner sheath and a waterproof layer; the outer skin of the waterproof cable can be made of materials such as polyvinyl chloride (PVC) or polyurethane (PU), which has waterproof, wear-resistant, anti-aging and other properties, and protects the internal wires and the insulation layer from external influences. The inner wire of the waterproof cable is covered with an insulating layer, which can be made of materials such as polyvinyl chloride (PVC), polyethylene (PE) or acrylate (PO), which has good insulation performance and chemical corrosion resistance. There may be electromagnetic interference between the internal wires and the insulation layer of the waterproof cable, so an electromagnetic shielding layer needs to be added. The shielding layer can include copper wire braided shielding or aluminum foil shielding. The inner sheath is to protect the internal structure and electrical performance of the waterproof cable, and the materials that can be used are PVC, PE, etc. In the inner layer of the waterproof cable, a layer of waterproof glue can be coated or an injection-molded waterproof seal can be added to avoid problems such as line short circuit or corrosion caused by water infiltration.

[0071] It should be noted that the charging device provided by the present invention is not only applicable to the swimming pool robot 20, but can also be applied to other electric equipment with underwater use requirements, such as underwater vacuum cleaners, underwater lighting equipment, underwater music equipment, etc.

[0072] The utility model adopts a carrier 10 as a transfer to guide the charging port of the swimming pool robot 20 above the water surface so that the charging port is compatible with the base station 30 on land, thereby solving the problems of narrow applicability, low charging efficiency, and affected safety of the charging method of the swimming pool robot 20 in the prior art.

[0073] See also Figure 1 , 6 As shown in Figures 7 and 8, in an optional embodiment of the present invention, the first charging unit 11 is exposed on the side or top surface of the carrier 10. It should be understood that in a specific embodiment, the base station 30 should be arranged as close to the edge of the swimming pool as possible, and part of the structure of the base station 30 can also be protruded above the water surface of the swimming pool, such as Figure 1 As shown, at this time, the first charging unit 11 is arranged on the side of the carrier 10, and accordingly, the second charging unit 31 can be arranged at the end of the protruding structure of the base station 30. When the carrier 10 moves to the edge of the swimming pool, the coupling of the first charging unit 11 and the second charging unit 31 can be easily achieved; of course, in some other embodiments, the part of the base station 30 protruding above the water surface can be lifted upward for a distance, so that a space capable of accommodating the carrier 10 is formed between the base station 30 and the water surface. At this time, the first charging unit 11 can be arranged on the top surface of the carrier 10, and accordingly, the second charging unit 31 can be arranged on the bottom surface of the protruding structure of the base station 30; in addition, the base station 30 can also be arranged at a position spaced a distance from the edge of the swimming pool. At this time, a protruding structure can be arranged on the carrier 10, so that when the carrier 10 moves to the edge of the swimming pool, the protruding structure can be cantilevered to the outside of the swimming pool. The first charging unit 11 can be arranged on the protruding structure, for example, on the top surface, side surface or bottom surface of the protruding structure. At this time, the second charging unit 31 needs to be correspondingly arranged on the bottom surface, side surface or top surface of the base station 30.

[0074] See also Figure 4As shown, in an optional embodiment of the utility model, a power mechanism can also be provided on the carrier 10 so that the carrier 10 can move to the vicinity of the base station 30 without the aid of external force, and the power mechanism is configured to drive the carrier 10 to turn and / or move on the water surface. In a specific embodiment, the power mechanism can include, for example, at least one blade 14 provided at the bottom of the carrier 10, and the blade 14 is connected to a motor provided on the carrier 10. Taking two blades 14 as an example, the two blades 14 can be provided in parallel with each other, and the two blades 14 are respectively provided at positions close to both sides of the carrier 10. In this case, the turning of the carrier 10 can be controlled by controlling the rotation speed of different blades 14. When the two blades 14 rotate at the same speed, the linear motion of the carrier 10 can be realized. In addition, the blades 14 can also be used in conjunction with a forward and reverse motor. When the two blades 14 rotate in the opposite direction, the carrier 10 can be turned in situ, further improving the flexibility of the carrier 10 during movement.

[0075] It should be understood that the specific form of the power mechanism is not unique. For example, in another embodiment, the power mechanism includes at least one blade disposed at the bottom of the carrier 10 and at least one steering rudder. The blade and the steering rudder are respectively connected to the motor disposed on the carrier 10. In this embodiment, the blade is mainly responsible for providing power for the carrier 10 to move forward, while the steering rudder is specifically responsible for controlling the movement direction of the carrier 10. For example, in some other embodiments, the blade itself can also be set as a swingable structure. In these embodiments, the movement direction of the carrier 10 can be controlled by adjusting the swing angle of the blade.

[0076] Furthermore, the movement of the carrier 10 may be autonomous or manually controlled; see Figure 5 As shown, for example, a positioning module 17 can be set on the carrier 10, and the carrier 10 determines the relative position between itself and the base station 30 through the positioning module 17, and then autonomously plans the movement path to move to the vicinity of the base station 30; for another example, a computer vision system 16 can be set on the carrier 10, such as an image acquisition module and an image recognition module, and the carrier 10 can determine the position of the base station 30 through the computer vision system 16 and autonomously move to the vicinity of the base station 30; for another example, a communication module 15 can be set on the carrier 10, and then the carrier 10 can be controlled to move to the vicinity of the base station 30 by remote control through the remote terminal 40, such as Figure 6 Of course, the communication module 15 may not be provided on the carrier 10, but the remote terminal 40 may send the control signal directly to the swimming pool robot 20, such as Figure 7 As shown, the swimming pool robot 20 then transmits the control signal to the carrier 10 via the cable 12 . It should be noted that although the existing wireless communication method has a low signal propagation efficiency in water, it can still transmit some simple control signals, which is sufficient to meet the control requirements of the carrier 10 .

[0077] Of course, in actual applications, the above-mentioned power mechanism, positioning module 17, computer vision system 16, communication module 15, etc. can all be removed, and the carrier 10 can be moved directly to the vicinity of the base station 30 by hand. In this case, in order to facilitate operation, hanging ears can be set on the carrier 10, and the operator can move the carrier 10 directly by the swimming pool through a pole or rope.

[0078] The above embodiments can all achieve the adaptation between the carrier 10 and the base station 30, and these embodiments should all fall within the scope of protection required by the present utility model.

[0079] See also Figure 8 , 9 As shown, in an optional embodiment of the utility model, a cable retracting mechanism 18 is further included, and the cable retracting mechanism 18 is installed on the carrier 10 or the body, and the cable retracting mechanism 18 is configured to be able to adjust the length of the cable 12 exposed outside the carrier 10 and the body. It should be understood that in this embodiment, when the swimming pool robot 20 has no charging and communication needs, the carrier 10 can be stored on the swimming pool robot 20 to avoid the carrier 10 and the cable 12 from interfering with the people in the swimming pool, especially to avoid the cable 12 from being entangled in the human body and causing safety hazards. Furthermore, a space specifically for accommodating the carrier 10 can also be set on the swimming pool robot 20, so that the carrier 10 can be accommodated inside the swimming pool robot 20 to avoid the carrier 10 from generating a large flow resistance during the movement of the swimming pool robot 20, thereby improving the endurance of the swimming pool robot 20.

[0080] See also Figure 8 , 9 As shown, in an optional embodiment of the present invention, the cable retracting mechanism 18 may include, for example, a winch mounted on the carrier 10 or the pool robot 20 , or other reel devices on the market that can accommodate the cable 12 may be used.

[0081] Furthermore, when the carrier 10 is designed to be a special-shaped structure, in order to facilitate the control of the posture of the carrier 10 when it is stored, the cables 12 can be divided into multiple bundles, and each bundle of cables 12 can be connected to different positions of the carrier 10 and the swimming pool robot 20; of course, if a circular carrier 10 is used, the cables 12 can be directly set at the center of the carrier 10.

[0082] See also Figure 2 , 3As shown, in an optional embodiment of the utility model, a holding unit is provided between the base station 30 and the carrier 10, and the holding unit is configured to keep the base station 30 and the carrier 10 at a current relative position when the first charging unit 11 is coupled with the second charging unit 31. In a specific embodiment, the holding unit includes a first magnetic unit 13 disposed near the surface of the carrier 10, and a second magnetic unit 32 disposed near the surface of the base station 30; in a preferred embodiment, in order to better maintain the relative position of the first charging unit 11 and the second charging unit 31, the first magnetic unit 13 should be disposed near the first charging coupling unit 11, and the second magnetic unit 32 should be disposed near the second charging coupling unit 31. Specifically, the relative position between the first magnetic unit 13 and the first charging coupling unit 11 should be symmetrical with the relative position between the second magnetic unit 32 and the second charging coupling unit 31, as shown in FIG. Figure 2 , 3 As shown, it is ensured that when the first magnetic unit 13 and the second magnetic unit 32 are attracted, the first charging unit 11 is just coupled with the second charging unit 31 .

[0083] See also Figure 2 , 3 As shown, in a further preferred embodiment, a plurality of first magnetic units 13 and second magnetic units 32 can be respectively provided, and the first magnetic units 13 and the second magnetic units 32 should be staggered in the horizontal direction to avoid the first magnetic unit 13 being adsorbed on the wrong second magnetic unit 32, resulting in the first charging unit 11 and the second charging unit 31 being unable to be effectively coupled. In an embodiment provided by the utility model, the first magnetic unit 13 can be provided at two diagonal corners of the first charging unit 11, and correspondingly, the second magnetic unit 32 can be provided at two diagonal corners of the second charging unit 31.

[0084] It should be understood that the magnetic unit can not only keep the carrier 10 and the base station 30 at a preset relative position, but also when the carrier 10 is close to the base station 30, the magnetic unit can automatically guide the carrier 10 to a state where the first charging unit 11 and the second charging unit 31 are aligned, avoiding repeated adjustments to the posture of the carrier 10 and simplifying the operation process. In addition, since the magnetic units are softly connected, when the pool robot 20 is away from the base station 30 or the pool robot 20 wants to store the carrier 10, the carrier 10 can be directly separated from the base station 30 by pulling.

[0085] In a specific embodiment, one of the first magnetic unit 13 and the second magnetic unit 32 is a permanent magnet, and the other can be an ordinary ferromagnetic material, such as steel, nickel, etc.; in some other embodiments, the permanent magnet can also be replaced by an electromagnet. When it is necessary to disconnect the connection between the carrier 10 and the base station 30, it is only necessary to cut off the power of the electromagnet, which can reduce or eliminate the tension on the cable 12 when the carrier 10 is separated from the base station 30.

[0086] It should be understood that the specific form of the holding unit is not unique. For example, in some other embodiments, the holding unit may also be a combination of a card slot and a buckle, a positioning block and a positioning slot, or a vacuum suction cup and a suction surface. These embodiments should all be applicable to the present utility model and fall within the scope of protection claimed by the present utility model.

[0087] In summary, the utility model adopts the carrier 10 as a transit to guide the charging port of the swimming pool robot 20 to above the water surface so that the charging port is compatible with the base station 30 on land, which solves the problems of narrow applicability, low charging efficiency, and affected safety in the charging method of the swimming pool robot 20 in the prior art; a signal transceiver module is arranged on the carrier 10, and the signal transceiver module is electrically connected to the controller of the swimming pool robot 20 through a cable 12, so that the carrier 10 is used as a communication antenna of the swimming pool robot 20 to facilitate the communication between the swimming pool robot 20 and the external terminal device, thereby solving the problem of low propagation efficiency of communication signals in water; when the swimming pool robot 20 has no charging and communication needs, the carrier 10 can be stored on the swimming pool robot 20 to avoid interference of the carrier 10 and the cable 12 to the people in the swimming pool, especially to avoid the cable 12 being entangled in the human body to cause safety hazards.
