Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] With the continuous development of technology and the continuous improvement of people's living standards, self-cleaning devices such as robot vacuum cleaners have become widely used in people's homes because they are more time-saving and labor-saving than traditional manual cleaning, greatly freeing up people's hands.

[0045] To better achieve cleaning functionality, current self-cleaning devices are equipped with robotic arms to move obstacles and collect items. However, since the grippers on the robotic arm only have the function of holding objects, the functionality achieved by adding a robotic arm to a robot vacuum cleaner is relatively limited, resulting in low utilization of the robotic arm.

[0046] In order to overcome the shortcomings of the existing technology, after repeated thinking and verification, the inventors discovered that if an accessory compartment is added to store the extended accessories that the robotic arm can grab and use, the robotic arm can autonomously grab the accessories in the accessory compartment, and a single device can switch between multiple cleaning modes, thereby breaking through the single-function limitation of traditional sweeping machines and simply adding a robotic arm, and improving the utilization of the robotic arm.

[0047] In view of this, this application provides an extension device for use in a self-cleaning device, the extension device comprising:

[0048] The housing is connected to the base station of the self-cleaning device, and the housing is provided with at least one accessory slot.

[0049] Accessories are detachable and located in corresponding accessory slots. These accessories are used to replace the robotic arms on the self-cleaning equipment to achieve different functions.

[0050] By incorporating at least one accessory slot on the housing and detachably storing accessories in the corresponding slot, the self-cleaning device's robotic arm can perform multiple cleaning functions as needed by replacing different accessories. This flexibility allows the device to adapt to various cleaning tasks. Changing accessories for the robotic arm breaks through the single-function limitations of traditional sweepers and simply adding robotic arms to existing devices. A single unit can switch between multiple cleaning modes, expanding the robotic arm's functionality and increasing its utilization. The self-cleaning device can flexibly adjust to different cleaning needs and environmental conditions, adapting to various usage scenarios, meeting the personalized needs of different users, and improving the user experience.

[0051] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0052] The following sections will provide a detailed description of the specific structure of the expansion device and various possible implementation methods.

Figure 10 is a fifth structural schematic diagram of the expansion device provided in the embodiments of this application. Figure 11 is a partially exploded structural schematic diagram of the expansion device shown in Figure 10.

[0054] As shown in Figures 1 and 4, the extension device 100 provided in this embodiment is used in a self-cleaning device. The extension device 100 is used to provide extension functionality for the robotic arm of the self-cleaning device.

[0055] Self-cleaning devices can be used in home life to automatically clean the house and can also be used to clean selected areas, saving time and effort and freeing up people's hands.

[0056] In one possible implementation, the self-cleaning device can be a robotic vacuum cleaner. However, it is not limited to this; in other possible implementations, the self-cleaning device can also be a combined sweeping and mopping robot, or other self-moving cleaning devices that meet cleaning needs.

[0057] As shown in Figure 2, the extension device 100 includes a housing 10 and accessories 20. The housing 10 is connected to the base station of the self-cleaning device. The housing 10 is used to store the accessories 20 that the robotic arm can grip.

[0058] The housing 10 is provided with at least one accessory slot 11. Accessories 20 are detachably disposed in the corresponding accessory slot 11. Accessories 20 are used to replace the robotic arm on the self-cleaning device to achieve different functions.

[0059] In one possible implementation, accessory 20 is used by grippers on a robotic arm to perform different functions.

[0060] As shown in Figure 8, in one possible implementation, accessory 20 can be detachably connected to the robotic arm. The gripper on the robotic arm is also one of the accessories 20, which can be detached from the robotic arm, so that the robotic arm can directly achieve different functions by connecting multiple different accessories 20.

[0061] By providing at least one accessory slot 11 on the housing 10, and detachably placing the accessory 20 into the corresponding accessory slot 11, the accessory 20 that expands the functionality of the robotic arm is stored. The robotic arm of the self-cleaning device can autonomously grip or directly connect and replace different accessories 20 as needed, thereby achieving multiple cleaning functions. This flexibility allows the device to adapt to different cleaning tasks. By replacing different accessories 20 with the robotic arm, the single-function limitations of traditional sweepers and simply adding robotic arms are overcome. A single device can switch between multiple cleaning modes, expanding the functionality of the robotic arm and improving its utilization. The self-cleaning device can flexibly adjust according to different cleaning needs and environmental conditions, adapting to various usage scenarios, meeting the personalized needs of different users, and improving the user experience. The modular design of the housing 10 and accessories 20 allows the device to be customized and expanded according to different market demands, exhibiting good design flexibility and market adaptability.

[0062] As shown in Figures 5 and 6, in one possible implementation, the accessory 20 includes a clamping part 21 and a functional part 22. The functional part 22 is connected to the clamping part 21 and located on the side of the clamping part 21 away from the opening of the accessory slot 11. The clamping part 21 is used for gripping with claws. The functional part 22 is used to implement various special functions.

[0063] By dividing accessory 20 into a clamping part 21 and a functional part 22, the design becomes more modular, making replacement and maintenance more convenient. The functional part 22 can be customized and replaced according to different cleaning tasks, such as installing different brush heads, mops, or other cleaning tools. This allows the device to quickly switch between different cleaning functions by gripping the clamping part 21 of different accessories 20 with its grippers. This design can adapt to different types of self-cleaning equipment and robotic arms, exhibiting good versatility and adaptability, facilitating its widespread application in various products.

[0064] The gripping part 21 is specifically designed to cooperate with the gripper of the robotic arm, ensuring that the accessory 20 is securely held during operation. This improves the stability and reliability of the equipment and reduces the risk of malfunctions caused by the accessory 20 becoming loose or falling off. The gripping part 21 is designed specifically for gripper hold, simplifying the robotic arm's operation. The robotic arm only needs to identify and grip the gripping part 21 to complete the replacement and use of the accessory 20, reducing operational complexity.

[0065] In one possible implementation, the clamping part 21 is provided with a clamping groove 211 for the robotic arm to extend into for clamping.

[0066] The gripping slot 211 provides a dedicated fixed position for the robotic arm's gripper, ensuring that the accessory 20 is securely grasped and held during gripping, reducing potential shaking or detachment of the accessory during operation, and improving equipment reliability. The design of the gripping slot 211 allows the robotic arm to more accurately position and grip the accessory 20, contributing to improved operational efficiency and ensuring quick and accurate completion of each accessory replacement or use. Because the gripping slot 211 provides a clear gripping position for the robotic arm, the operating procedure can be simplified, reducing the complexity of locating and gripping the accessory 20 and increasing automation. The design of the gripping slot 211 also reduces the risk of misoperation, minimizing equipment damage or malfunction due to improper gripping, and improving overall operational safety.

[0067] The gripping slot 211 provides a dedicated gripping area, reducing friction and wear between the robotic arm gripper and other parts of the accessory 20, thereby extending the service life of the accessory 20 and the robotic arm.

[0068] The clamping slot 211 can be adjusted and optimized according to different robotic arm designs, offering high design flexibility and adaptability to various types of self-cleaning equipment and robotic arms. This design makes the device more intuitive and user-friendly during use, eliminating concerns about accessory installation and clamping, thus improving the user experience.

[0069] In one possible implementation, the groove wall of the clamping groove 211 is provided with a biting member 212, which is used to abut against the gripper to achieve clamping of the accessory 20.

[0070] The engagement element 212 provides additional contact and abutment points, increasing the friction and clamping force between the gripper and accessory 20. This ensures greater stability of accessory 20 during operation, reduces the risk of slippage or dislodgement, and improves overall operational safety. Through the abutment between the engagement element 212 and the gripper, accessory 20 maintains greater stability during clamping, reducing displacement caused by vibration or external forces and improving the reliability of equipment operation. The engagement element 212 also helps the robotic arm's gripper achieve precise positioning within the clamping slot 211, ensuring that accessory 20 is accurately grasped and placed during each operation, improving the equipment's operational efficiency and automation level.

[0071] The design of the gripper 212 reduces the risk of misoperation of the gripper during the clamping process, ensuring that the accessory 20 can be correctly clamped and used, thus reducing the equipment failure rate. By providing a more stable grip, the gripper 212 reduces wear between the gripper and the accessory 20, thereby extending the service life of both the accessory 20 and the robotic arm.

[0072] In one possible implementation, when the robotic arm extends into the gripping slot 211, the gripper of the robotic arm opens to abut against the engagement member 212, thereby gripping the accessory 20.

[0073] The clamping groove 211 has a meshing element 212 on its wall, allowing the gripper to engage with the meshing element 212 through an internal support mechanism. When the robotic arm is closed, it extends into the clamping groove 211 and then opens the gripper to abut against the meshing element 212 on the inner wall of the clamping groove 211. This design allows the clamping groove 211 of the accessory 20 to be as small as possible, thus minimizing the width of the extension device 100 and saving overall equipment space. The internal support clamping also distinguishes the action of gripping the accessory 20 from other operating modes, reducing the risk of misoperation and improving safety. The internal support design ensures that friction is evenly distributed during clamping, reducing localized stress concentration, decreasing wear on the accessory 20 and the gripper, and extending their service life. Furthermore, when the gripper is working with the accessory 20, it is hidden within the clamping groove 211 inside the accessory 20, reducing the possibility of collisions with external obstacles, thereby improving equipment safety and reducing the risk of the accessory 20 falling off or equipment malfunction due to collisions.

[0074] In one possible implementation, the engaging member 212 is a toothed member provided on the wall of the clamping groove 211.

[0075] The jaws engage with the teeth on the inner wall of the clamping groove 211 to provide a secure grip, ensuring that the parts will not loosen or fall off during operation.

[0076] In one possible implementation, accessory 20 includes at least one of brush accessory 23, cleaning accessory 24, and vacuuming accessory 25.

[0077] By providing a variety of accessories 20, the device can perform a variety of cleaning tasks. Different accessories 20 are optimized for specific cleaning tasks, improving cleaning efficiency. For example, the brush accessory 23 can be used to sweep away dust and debris, the cleaning accessory 24 is suitable for wet wiping or deep cleaning, such as using a sponge or scouring pad on the functional section 22, while the vacuuming accessory 25 is used to pick up fine particles and dust. This versatility allows the device to adapt to different cleaning needs and environments. The device can select the appropriate accessory 20 according to the specific cleaning task and environmental conditions, thereby achieving the best cleaning effect, improving the device's practicality and user satisfaction. The device can automatically identify and replace different accessories 20 without manual intervention, simplifying the operation process and enhancing the user experience. Each accessory 20 can be replaced or cleaned individually as needed, simplifying the device's maintenance process and extending its lifespan.

[0078] Accessory 20 may also include spray accessories, scraper accessories, bucket accessories, and other accessories to achieve other functions. For example, spray accessories are used to spray cleaning agents on dirty areas, scraper accessories are used to scrape off dirt, and bucket accessories are used to collect dirt.

[0079] As shown in Figure 9, in one possible implementation, the accessory slot 11 corresponding to the vacuuming accessory 25 is a vacuuming slot 111. As shown in Figure 10, the housing 10 is provided with a dust channel 16, which is connected to the base station. As shown in Figure 11, the vacuuming slot 111 is provided with a dust collection opening 112, which is connected to the dust channel 16. The vacuuming accessory 25 is provided with a dust collection port 254, which is connected to the dust collection opening 112.

[0080] In one possible implementation, the dust duct 16 is directly connected to the dust collection bag of the base station.

[0081] During dust collection, by connecting the dust collection port 254 of the vacuum accessory 25 with the dust collection opening 112 and the dust channel 16, dust and debris can be directly sucked into and transferred to the dust collection bag of the base station by passing through the dust collection port 254, the dust collection opening 112, and the dust channel 16 in sequence. This direct dust collection path improves vacuuming efficiency and ensures a more thorough cleaning effect. Since dust and debris are directly transferred to the dust collection bag, accumulation inside the vacuum accessory 25 is reduced, decreasing the frequency of cleaning and maintenance of the vacuum accessory 25 and extending the service life of the equipment. The dust collection bag centrally collects dust and debris, reducing secondary dust transmission in the air and improving indoor air quality and hygiene. Users only need to replace or empty the dust collection bag periodically, eliminating the need for frequent cleaning of the dust inside the vacuum accessory 25, simplifying the operation process and improving the user experience.

[0082] In one possible implementation, the extension device 100 further includes an air duct conversion structure 30. The power end 31 of the air duct conversion structure 30 is connected to the suction end of the base station. The air duct conversion structure 30 connects the dust duct 16 to the dust bag of the base station.

[0083] By setting up the air duct conversion structure 30, the suction power of the base station itself is cleverly used as the power source for emptying the vacuum cleaner accessory 25. There is no need to set up an additional fan for emptying the vacuum cleaner accessory 25 on the expansion device 100 or the base station, which simplifies the overall structure, reduces manufacturing costs and weight, and helps to further miniaturize and lighten the weight, thereby improving the comfort of use.

[0084] Meanwhile, the suction power of the base station is typically stronger and more stable. This stronger suction can more thoroughly remove dust and debris from the vacuuming accessory 25 and dust duct 16, especially compacted or tangled hair and fibers, reducing residue. Furthermore, the air duct conversion structure 30 can be designed with air ducts to guide airflow into the dust bag along the optimal path and direction, creating a "tornado" effect or directional blowing, further improving emptying efficiency and preventing dust accumulation in dead corners.

[0085] As shown in Figures 2 and 7, in one possible implementation, the vacuum cleaner accessory 25 is provided with a charging electrode 251, and a charging component 12 is provided in the accessory slot 11 corresponding to the vacuum cleaner accessory 25. The charging component 12 is used to be electrically connected to the charging electrode 251 to charge the vacuum cleaner accessory 25.

[0086] By setting a charging electrode 251 on the vacuum cleaner accessory 25 and setting a charging component 12 in the accessory slot 11, the vacuum cleaner accessory 25 can be charged directly without being disassembled, ensuring that it is always in a usable state, improving the working efficiency and reliability of the equipment. The equipment can automatically complete the charging process of the vacuum cleaner accessory 25 without human intervention, improving the automation level of the equipment and reducing the user's operating burden. Users do not need to manually charge the vacuum cleaner accessory 25; the equipment can complete this process automatically, simplifying the operation process and improving the user experience.

[0087] In one possible implementation, accessory 20 does not require charging and can be powered directly by the robotic arm.

[0088] The fact that accessory 20 has its own power supply system leads to a complex design and heavy weight, making it difficult for the robotic arm to control accessory 20 to perform precise cleaning tasks. Using the robotic arm to power accessory 20 can reduce design complexity and achieve a lighter weight, thereby facilitating precise control of the robotic arm.

[0089] In one possible implementation, the vacuuming accessory 25 has a power connector 26 on the side near the opening of the accessory slot 11. The power connector 26 is used for electrical connection with the power supply on the robotic arm.

[0090] Integrating the battery, motor drive circuit, and related structural support components into the vacuuming accessory 25 would result in a complex structure, large size, and significantly increased weight. By removing the heavy power supply unit (battery, high-power circuit) from the vacuuming accessory 25 and connecting it to the robotic arm via the power connector 26, the vacuuming accessory 25 can be directly powered by the robotic arm or self-cleaning device. The vacuuming accessory 25 retains only the core functional components (such as the roller brush, motor, and light) and a lightweight power connector, greatly reducing its weight. This allows the robotic arm to grasp, move, and place the vacuuming accessory 25 with lower power consumption, faster speed, and higher precision.

[0091] Meanwhile, the vacuum cleaner accessory 25 eliminates the need for a battery compartment and complex circuitry, simplifying the structure, reducing costs, making it easier to manufacture and maintain, and increasing reliability.

[0092] In one possible implementation, the vacuuming accessory 25 includes a communication unit that is communicatively connected to the self-cleaning device.

[0093] Through the communication unit, the vacuuming accessory 25 can transmit information such as its working status, performance data, and battery level to the self-cleaning device in real time. This allows the device to monitor the status of the vacuuming accessory 25 in real time and make adjustments when necessary, improving the device's intelligence. The self-cleaning device can dynamically adjust its working mode and parameters based on the data transmitted by the vacuuming accessory 25 to optimize cleaning effect and energy consumption, helping to improve the overall performance and efficiency of the device. The communication unit can help identify and diagnose faults or abnormalities in the vacuuming accessory 25, and promptly notify the user or automatically take corrective measures, reducing equipment downtime and maintenance costs.

[0094] Through the communication connection, users can remotely control the operation of the vacuuming accessory 25 or wirelessly update its software and firmware to obtain the latest features and performance improvements. Users can view the status and performance data of the vacuuming accessory 25 through the self-cleaning device's interface or mobile application, gaining a more intuitive user experience and greater operational convenience. The communication unit can promptly send alarms when abnormal conditions (such as overheating or battery failure) are detected, helping to prevent potential safety hazards.

[0095] In one possible implementation, the vacuuming accessory 25 includes a manual switch 252.

[0096] In some situations, users may want to quickly activate the vacuuming function without using the main device or remote control. The manual switch 252 provides a convenient solution, especially for emergency cleaning or spot cleaning, where the vacuuming accessory 25 can be used as a manual handheld vacuum. Users can directly control the vacuuming accessory 25's on and off via the manual switch 252, making the device more flexible in use. Users can immediately start or stop the vacuuming function as needed. The manual switch 252 allows users to turn off the device when the vacuuming function is not needed, saving energy, extending battery life, and reducing unnecessary energy consumption. The manual switch 252 is generally designed to be intuitive and easy to use, requiring no complicated operations, making it suitable for users of all ages.

[0097] Meanwhile, the manual switch 252 can quickly shut down the equipment in emergencies, preventing damage or safety hazards caused by unexpected conditions such as blockage or overheating. In the event of a malfunction in the automatic control system, the manual switch 252 provides a backup operating method, ensuring the equipment can continue to be used until the problem is resolved.

[0098] In one possible implementation, the vacuuming accessory 25 is provided with a charging port 253.

[0099] By incorporating a charging port 253 on the vacuum cleaner accessory 25, the vacuum cleaner accessory 25 can be charged independently of the main device, allowing users to charge the vacuum cleaner accessory 25 without using the main device, thus improving the device's flexibility and convenience. The charging port 253 provides a simple and intuitive charging method, eliminating the need for complicated operations and enhancing the overall user experience. The charging port 253 also allows users to charge the vacuum cleaner accessory 25 anywhere there is a power outlet, no longer limited to a specific charging base or location, increasing its usability.

[0100] In one possible implementation, the charging interface 253 is a Type-C charging port.

[0101] The Type-C charging port is the current standard charging interface. Through the standardized charging interface 253 design, the compatibility of the vacuum cleaner accessory 25 with other charging devices can be improved. Users can use a universal charger to charge the vacuum cleaner accessory 25, reducing the dependence on dedicated charging devices.

[0102] In one possible implementation, the housing 10 is detachably connected to the base station.

[0103] The detachable design allows users to easily separate the housing 10 from the base station, facilitating cleaning and maintenance of the internal components and helping to maintain the device in good working order and extend its lifespan. The detachable design also allows users to remove the housing 10 from the base station as needed, making it convenient for use in different locations or environments, thus improving the device's applicability and portability.

[0104] Meanwhile, in the event of a malfunction, users can quickly disassemble housing 10 to inspect and repair the problem, reducing equipment downtime and simplifying maintenance. The detachable connection supports a modular design, allowing users to replace or upgrade specific components (such as replacing housing 10 with different functions) as needed, improving the device's scalability and adaptability.

[0105] When equipment needs to be transported or stored, the detachable design allows the equipment to be broken down into smaller parts, reducing its footprint and simplifying transportation and storage.

[0106] As shown in Figure 3, in one possible implementation, the housing 10 is provided with a connector 13, and the connector 13 is provided with a snap-fit ​​structure 131 to snap-fit ​​with the base station.

[0107] The snap-fit ​​structure 131 allows users to quickly and easily connect or disconnect the housing 10 from the base station without the need for tools or complex operations, improving the operational efficiency of the device. The snap-fit ​​structure 131 provides a secure connection, ensuring that the housing 10 will not accidentally separate from the base station during use, thus improving the safety and reliability of the device. Compared to bolts or other fasteners, the snap-fit ​​structure 131 typically reduces wear on components during connection and disconnection, thereby extending the lifespan of the device.

[0108] Meanwhile, the snap-fit ​​design is typically intuitive and easy to use, allowing users to easily understand and operate it, thus improving the overall user experience and satisfaction. When maintenance or component replacement is required, the snap-fit ​​structure 131 makes the process simpler and faster, reducing maintenance time and costs.

[0109] In one possible implementation, the connector 13 is rotatably mounted on the housing 10 to hide the snap-fit ​​structure 131 when the housing 10 is separated from the base station.

[0110] The rotatable design is generally easy to operate, and users can easily hide or show the snap-fit ​​structure 131, improving the ease of use of the device.

[0111] By concealing the snap-fit ​​structure 131 when the device is detached, it can be effectively protected from dust, dirt, and physical damage, thereby extending its service life and maintaining its functionality. At the same time, the concealed snap-fit ​​structure 131 reduces the possibility of accidental contact or misoperation by the user when the device is detached, improving the device's safety. In the detached state, the concealed snap-fit ​​structure 131 reduces the risk of accidental contact by the user or other objects, minimizing potential safety hazards.

[0112] The concealed snap-fit ​​structure 131 makes the appearance of the housing 10 cleaner and more aesthetically pleasing, enhancing the product's visual appeal and user experience. The concealed snap-fit ​​structure 131 reduces exposed, complex components, making the surface of the housing 10 easier to clean and maintain.

[0113] In one possible implementation, when the housing 10 is separated from the base station, the connector 13 can be flipped (e.g., flipped 180 degrees) under the action of gravity or spring, or it can be flipped manually to hide the snap-fit ​​structure 131, so that the outer surface of the expansion device 100 is flat and aesthetically pleasing.

[0114] In one possible implementation, the housing 10 is fixedly connected to the base station.

[0115] The fixed connection ensures a secure bond between the housing 10 and the base station, reducing the risk of loosening or separation due to vibration or movement during use, and improving the overall stability and reliability of the equipment. Because no additional connection mechanisms (such as snap-fit ​​structures or connectors) are required, the fixed connection simplifies the design and manufacturing process, thereby reducing production costs and complexity. With no removable parts, the fixed connection reduces maintenance and replacement required due to wear or damage to connectors, lowering maintenance costs and complexity. The fixed connection also reduces the likelihood of users accidentally separating the housing 10 from the base station during operation, improving equipment safety, especially in applications requiring stable operation.

[0116] The fixed connection ensures that the housing 10 and the base station are always in optimal position and alignment, providing consistent performance and functionality and reducing performance degradation caused by positional misalignment. The fixed connection design reduces the possibility of user error or accidental disassembly during use, making it particularly suitable for environments requiring high security and reliability. With no moving parts, the fixed connection reduces failures due to mechanical fatigue or wear, improving the durability and lifespan of the equipment.

[0117] In one possible implementation, the housing 10 is electrically connected to the base station.

[0118] Electrical connectivity ensures that the electronic components or accessories 20 within housing 10 continuously draw power from the base station, thereby guaranteeing continuous operation and functional stability of the device. Electrical connectivity enables not only power transmission but also bidirectional data transmission. This allows sensors or other electronic devices within housing 10 to communicate with the base station in real time, supporting more complex and intelligent functions. Electrical connectivity reduces the need for wireless transmission modules or independent power supplies, thereby simplifying device design, reducing manufacturing costs, and minimizing potential points of failure.

[0119] Wired electrical connections are generally more stable and less susceptible to interference than wireless connections, ensuring reliable operation of devices in various environments. Wired connections also offer better data transmission security, reducing the risk of signal interception or interference that can occur with wireless transmissions. Furthermore, direct electrical connections are typically more energy-efficient than wireless transmissions, reducing the additional energy consumption caused by wireless communication and improving the overall energy efficiency of the device.

[0120] In one possible implementation, the housing 10 is provided with an electrical connector for electrical connection to the base station.

[0121] Electrical connectors ensure that housing 10 receives a stable power supply from the base station, supporting continuous operation and functional stability of the equipment, especially suitable for equipment requiring long-term operation. Electrical connectors are not only used for power transmission but also for data transmission, ensuring reliable communication between housing 10 and the base station, facilitating more complex functions such as real-time monitoring and remote control. The use of electrical connectors supports modular design, allowing different housings 10 or base stations to be interchangeable or upgraded, improving the flexibility and adaptability of the equipment.

[0122] If the housing 10 contains a battery, the electrical connector can be used for efficient charging, ensuring that the device can be automatically recharged when not in use, keeping the device always available.

[0123] In one possible implementation, the electrical connector includes at least one of a spring electrode 14 and a wire.

[0124] By employing spring electrodes 14 or wires, it is possible to adapt to different equipment layouts and design requirements, providing greater design flexibility and making it suitable for a variety of application scenarios.

[0125] The spring electrode 14 provides stable electrical contact, maintaining a good connection even when the device is subjected to vibration or slight movement, ensuring continuous power supply and data transmission. The spring electrode 14 has a degree of elasticity, automatically adjusting to adapt to different contact surface or positional changes, reducing the need for precise alignment and improving connection reliability. The spring electrode 14 is typically made of durable materials, capable of withstanding multiple connection and disconnection cycles without affecting performance, extending the device's lifespan. The design of the spring electrode 14 simplifies and speeds up the connection process between the housing 10 and the base station, eliminating the need for complex alignment or locking mechanisms and enhancing user convenience.

[0126] Wires provide a flexible connection method, allowing devices to be moved or repositioned within a certain range without interrupting power or data transmission.

[0127] In one possible implementation, the spring electrode 14 includes an elastic element 141 and an electrical connector 142, with the elastic element 141 abutting against the electrical connector 142 to electrically connect the electrical connector 142 to the base station when the housing 10 is connected to the base station.

[0128] The elastic element 141 provides continuous contact pressure, ensuring good contact between the electrical connector 142 and the base station, guaranteeing stable power supply and data transmission, and maintaining connection even when the equipment is subjected to vibration or slight movement. Because the elastic element 141 absorbs and mitigates mechanical stress during the connection process, it reduces wear on the contact surfaces between the electrical connector 142 and the base station, extending the component's lifespan.

[0129] In one possible implementation, the spring electrode 14 further includes a positioning element 143, which is used to position the electrical connector 142 when the housing 10 is connected to the base station, so that the electrical connector 142 is electrically connected to the base station.

[0130] Positioning element 143 ensures that electrical connector 142 is accurately aligned with the corresponding contact point of the base station during connection, reducing the possibility of connection errors and improving the reliability of the electrical connection. Positioning element 143 helps users find the correct position and angle more easily when connecting housing 10 and base station, simplifying the installation process and improving user experience. By ensuring the correct positioning of electrical connector 142, wear and damage caused by misalignment are reduced, extending the service life of the contact surface between electrical connector 142 and base station.

[0131] In one possible implementation, the positioning element 143 includes a magnet that is magnetically attached to the base station to position the electrical connector 142.

[0132] The magnetic attraction of the magnet automatically aligns the housing 10 with the base station, ensuring that the electrical connector 142 accurately contacts the corresponding contact point on the base station, reducing errors caused by human alignment. Users simply need to bring the housing 10 close to the base station, and the magnet will automatically attract and align it, simplifying the connection process and improving user experience and ease of operation. Magnetic connection allows users to quickly connect and disconnect the housing 10 from the base station, making it suitable for applications requiring frequent connection and disconnection, thus improving work efficiency.

[0133] Because magnetic connections reduce the need for mechanical locking or plugging / unplugging, they reduce wear on electrical connectors 142 and the base station during connection and disconnection, extending the lifespan of the equipment. The magnets provide a certain degree of attraction, ensuring that the housing 10 and the base station maintain a stable connection even during slight vibrations or movement, reducing the risk of poor contact.

[0134] In one possible implementation, the accessory slots 11 include a plurality of slots 11 located on the same side of the housing 10.

[0135] Multiple accessory slots 11 allow users to install different accessories 20 as needed, enabling a modular design of the device and enhancing its flexibility and functional expandability. Concentrating multiple accessory slots 11 on one side helps optimize the internal and external space layout of the device, allowing other sides to be used for different functions or design requirements. The accessory slots 11, concentrated on one side, make connecting and managing accessories 20 easier, allowing users to more easily install, disassemble, and maintain them. Concentrating the accessory slots 11 on one side also keeps the other sides of the housing 10 neat and aesthetically pleasing, enhancing the product's visual appeal and user experience.

[0136] In one possible implementation, multiple accessory slots 11 are arranged sequentially along the vertical direction.

[0137] The vertically arranged accessory slots 11 effectively utilize the equipment's height and save lateral space, significantly reducing the footprint and making the overall equipment more compact. This makes it suitable for space-constrained applications and better meets user needs. The vertical arrangement also makes it easier for users to install or remove accessories 20, especially when the equipment is tall, allowing users to operate from top to bottom. The vertically arranged accessory slots 11 also support modular design, allowing users to add or replace accessories 20 as needed, enabling flexible functional expansion. Furthermore, the vertically arranged accessory slots 11 make the inspection, maintenance, and management of accessories 20 more systematic, allowing users to inspect and maintain each accessory 20 from top to bottom.

[0138] The vertical arrangement design simplifies internal wiring, allowing cables to be neatly arranged vertically, reducing cable crossings and tangles, and improving the cleanliness and ease of maintenance of the equipment.

[0139] In one possible implementation, the expansion device 100 may also be provided with an accessory slot 11, and multiple expansion devices 100 are stacked in sequence along the vertical direction, so that multiple accessory slots 11 are arranged in sequence along the vertical direction.

[0140] In one possible implementation, the housing 10 is further provided with a storage cavity 15, which is located at the top of the housing 10.

[0141] The storage compartment 15 provides additional storage space, allowing users to conveniently store small tools, accessories 20, or other items, improving the equipment's usability. The top-positioned storage compartment 15 enables users to quickly access stored items when needed, reducing search and retrieval time and improving work efficiency. The storage compartment 15 on the top of the equipment effectively utilizes the overall space without occupying the main operating space, making it suitable for environments with limited space. The storage compartment 15 helps users centrally store frequently used small items, reducing clutter in the work area and maintaining a clean and orderly environment around the equipment. Storing small items in the storage compartment 15 reduces the risk of items falling or getting lost, especially in environments with frequent movement or vibration.

[0142] By adding the storage compartment 15, the expansion device 100 is no longer just a single-function tool, but also possesses additional storage capabilities, enhancing the overall value of the device. Providing the storage compartment 15 improves the user experience, making the device more user-friendly and closer to user needs, thereby increasing user satisfaction.

[0143] In one possible implementation, accessory 20 is detachably connected to and / or detachably electrically connected to the robotic arm.

[0144] By connecting accessory 20 to the robotic arm electrically, meaning accessory 20 is powered by the robotic arm, accessory 20 can retain only its core functional components, thereby simplifying the accessory design, reducing its weight, and allowing the robotic arm to more precisely control accessory 20 to perform accurate cleaning tasks.

[0145] Meanwhile, when accessory 20 is not grasped by the robotic arm, the circuit is completely disconnected, accessory 20 does not consume any power, and the robotic arm will not supply power to idle interfaces, achieving zero standby power consumption, which is energy-saving and environmentally friendly.

[0146] The electrical connection can be designed to be completed automatically during the robotic arm's grasping of accessory 20, combining the "grabbing" and "connection" actions into one, simplifying the overall workflow and improving system efficiency. Power supply is only established at the moment the robotic arm grasps accessory 20 and establishes the electrical connection. This allows the system to intelligently allocate power only to the currently used tool, improving system energy efficiency.

[0147] With detachable electrical connections, the robotic arm can automatically change different accessories for different cleaning tasks within a work cycle, without interrupting the core power supply of the system, thus achieving seamless switching of functions.

[0148] Integrating the power supply function into the "grasping end" of the robotic arm, rather than placing accessory 20 in a fixed position on the extension device 100, means that the robotic arm does not need a very precise fixed docking socket to maintain power supply when picking up and placing accessory 20, thus reducing the requirements for the positioning accuracy of accessory 20.

[0149] Accessory 20 becomes a completely independent module, allowing users to purchase, upgrade, or repair it separately without having to consider complex circuit integration issues. If accessory 20 is damaged, it can be directly replaced, resulting in low maintenance costs and a simple process.

[0150] In one possible implementation, the accessory 20 is provided with a quick-release structure 27 on the side near the opening of the accessory slot 11, and the accessory 20 is detachably electrically connected to the robotic arm through the quick-release structure 27.

[0151] In one possible implementation, the power connector 26 is located on the quick-release structure 27, and the accessory 20 is electrically connected to the robotic arm via the power connector 26.

[0152] The quick-release structure 27, such as snap-fit, rotary lock, and magnetic lock, provides stable and continuous mechanical pressure when locked. This pressure directly ensures a tight and reliable contact between the pins and sockets of the connector 26, effectively preventing power disconnection, signal interruption, or arcing caused by vibration or slight movement, thus ensuring the reliability and safety of the electrical connection. The rigid connection of the quick-release structure 27, as the main load-bearing structure, bears all the torque and stress when the robotic arm operates the accessory 20, while the precision electrical contacts are only responsible for transmitting electrical energy and signals and are unaffected by external forces, thereby extending the service life of the connector 26.

[0153] Simultaneously, the system can definitively determine whether the electrical connection has been securely established by checking the locking state of the quick-release structure 27 (e.g., by adding a microswitch). Power is only permitted after mechanical locking confirmation, providing a safety interlock mechanism.

[0154] The quick-release structure 27 is positioned on the side closest to the opening of the accessory slot 11, meaning this is the area where the robotic arm first contacts and last separates from the accessory 20. This facilitates gripping by the robotic arm's end effector. Simultaneously, the quick-release structure 27 is concentrated at the edge, leaving layout space for internal functional components of the accessory 20 (such as motors and air ducts), contributing to a more compact and efficient design for the accessory 20.

[0155] In one possible implementation, the housing 10 is provided with an unlocking structure 17, which is used to cooperate with the quick-release structure 27 to remove the accessory 20 inserted into the accessory slot 11 from the robotic arm.

[0156] In one possible implementation, the unlocking structure 17 has a pressing part on the side facing the accessory slot 11. The quick-release structure 27 connecting the robotic arm and the accessory 20 is provided with a locking button for unlocking.

[0157] When the robotic arm enters the accessory slot 11 without accessory 20 installed, the robotic arm engages with accessory 20 via quick-release structure 27. When the robotic arm enters the accessory slot 11 with accessory 20 installed, the pressing part of unlocking structure 17 touches the locking button of quick-release structure 27, thereby unlocking the robotic arm from accessory 20.

[0158] The setting of the unlocking structure 17 automates the action of removing part 20, just like the action of grasping part 20, thus completing the closed loop of the operation. By setting the quick-release structure 27 on part 20 and the unlocking structure 17 in part slot 11, when picking up, the robotic arm only needs to align with the quick-release structure 27 on part 20 to complete the connection between the robotic arm and part 20; when removing, the robotic arm only needs to align part 20 with the corresponding part slot 11 and put it in, and the unlocking structure 17 in part slot 11 will automatically trigger the quick-release structure 27 on part 20 to remove part 20, thus realizing a fully automated closed loop from "grabbing-use-returning and removal".

[0159] Simultaneously, the function of the unlocking structure 17, which requires a certain amount of force and a complex mechanical structure, is separated from the robotic arm and transferred to the extension device 100. The robotic arm can be designed to be very simple, without the need to integrate a bulky or sophisticated unlocking structure, reducing the load, complexity, and failure rate of the robotic arm. During operation, the unlocking force is provided only by the fixed unlocking structure 17, fundamentally preventing the risk of the robotic arm accidentally colliding with other objects during movement or cleaning, triggering the unlock and causing the accessory 20 to fall off.

[0160] The cooperation between the unlocking structure 17 and the quick-release structure 27 is itself a positioning process, ensuring that the accessory 20 is placed in the predetermined position in the accessory slot 11 every time it is removed, without tilting or falling off, thus ensuring the standardization and stability of the storage of the accessory 20.

[0161] In one possible implementation, the housing 10 has an accessory compartment 18 movably disposed therein, and the accessory slot 11 is disposed on the accessory compartment 18.

[0162] Because the robotic arm and accessory 20 are electrically connected via a detachable mechanical connection, a high degree of precision is required for the connection; even a slight deviation will prevent it from connecting. By using the accessory compartment 18, which is movable within the housing 10, the accessory slot 11 for holding accessory 20 can float within the housing 10. Distance errors during the robotic arm docking process can be automatically corrected by the floating accessory slot 11 to adjust the position of accessory 20, achieving precise docking between the robotic arm and accessory 20 and enabling rapid replacement of accessory 20. The movement of the accessory compartment 18 compensates for the limitations of the robotic arm's working range and precision, reducing the requirements for the robotic arm's length and degrees of freedom, thus allowing for a simpler, lower-cost, and more reliable robotic arm structure.

[0163] If the accessory compartment 18 or its unlocking structure 17 or sensors malfunction, it can be repaired or replaced as an independent module without replacing the entire housing 10, making maintenance easy. At the same time, placing the accessory slot 11 in a separate accessory compartment 18, which, as a relatively enclosed active unit, helps to confine contaminants such as dust and hair to a smaller area, making cleaning easier and preventing contamination of other precision components inside the expansion device 100.

[0164] In one possible implementation, the accessory compartment 18 includes an elastic portion 181 and at least one compartment portion 182 disposed on the elastic portion 181, the accessory slot 11 is disposed on the compartment portion 182, and the elastic portion 181 is connected to the housing 10.

[0165] In one possible implementation, the elastic part 181 is made of soft rubber, allowing the accessory compartment 18 to float freely within the housing 10.

[0166] When the robotic arm picks up or puts back accessory 20, it is difficult to achieve 100% center alignment every time. Rigid connections can lead to impacts, jamming, or wear of the locating pins. The elastic portion 181 (such as a spring, spring sheet, or silicone pillar) provides a buffer stroke, absorbing the impact force and positional deviation generated during docking, preventing hard collisions that could damage accessory 20, the robotic arm, or accessory slot 11. The elastic support of the elastic portion 181 makes the cabin portion 182 a "floating platform." At the moment the robotic arm contacts accessory 20, the cabin portion 182 can make slight translations or deflections within the range of the elastic portion 181, automatically adapting to the actual position of the robotic arm and guiding accessory 20 smoothly into the correct connection or storage posture. The elasticity of the elastic portion 181 also allows the cabin portion 182 to automatically reset. Through buffering and self-adaptation, the mechanical stress borne by the robotic arm, accessory 20, quick-release structure 27, and accessory slot 11 is greatly reduced, effectively preventing problems such as cracking of plastic parts and fatigue of metal parts caused by repeated impacts and forced alignment.

[0167] When performing the "return" action, the robotic arm does not need to pursue an absolutely precise and unique point. Simply placing the accessory 20 into the accessory slot 11 is sufficient; precise positioning is not required. The accessory 20, once in the slot 11, will exert a certain deformation force on the elastic part 181. Under the elastic force of the elastic part 181, the accessory slot 11 in the cabin part 182 will move adaptively towards the accessory 20. The system can then achieve the final precise positioning automatically through the mechanical structure. This reduces the requirements for the robotic arm's motion control algorithm, making its movements faster and its programming simpler.

[0168] The internal structural components of the expansion device 100 will vibrate during operation. The elastic part 181 can act as a vibration isolation to prevent these vibrations from being directly transmitted to the cabin part 182 and the precision parts 20 stored therein, especially the parts 20 with electronic components, thereby improving the durability of the entire system.

[0169] In one possible implementation, the shell 10 is also provided with a fixing rope 183. One end of the fixing rope 183 is connected to the shell 10, and the other end is connected to the cabin section 182.

[0170] In one possible implementation, the fixing rope 183 is made of steel wire.

[0171] The cabin part 182 is fixed in the shell 10 by the cooperation of the elastic part 181 and the fixing rope 183, so that the cabin part 182 can float freely inside the shell 10. The elastic part 181 can make the cabin part 182 automatically reset, and the fixing rope 183 provides reliable movement restriction.

[0172] After prolonged use, the connection points of the elastic part 181 may be at risk of fatigue fracture. Alternatively, the cabin part 182 may be ejected in the event of an unexpected and significant external impact. The fixing rope 183, acting as an independent physical restraint, can firmly hold the cabin part 182 even in the event of such extreme circumstances, preventing it from completely detaching from the shell 10 and avoiding damage to the cabin part 182 and the accessories 20 placed inside, or even injury to the user.

[0173] Meanwhile, although the movable accessory compartment 18 has the aforementioned advantages, an excessively large range of motion can cause certain problems. For example, the accessory slot 11, moving under the elastic force of the elastic part 181, can cause the accessory 20 placed inside to move around. If the range of motion is too large, it will affect the docking between the robotic arm and the accessory 20, thus interfering with the retrieval and placement function. It may also cause excessive pulling of the cable of the accessory 20 placed in the compartment 182, or interference or collision between the accessory 20 and the housing 10. The length of the fixing rope 183 precisely limits the maximum range of motion of the compartment 182 on the elastic part 181, ensuring that it always moves within a preset, safe area. By limiting the range of motion, it is ensured that the robotic arm can always reach the accessory slot 11 on the compartment 182, and that the compartment 182 can accurately return to its initial position when retracting, without getting stuck or unable to reset due to excessive deviation.

[0174] In one possible implementation, the accessory slot 11 includes a cleaning slot 113. The extension device 100 also includes a drying fan 40, and the housing 10 is provided with a drying air duct 19, which communicates with the cleaning slot 113. The drying fan 40 is located at the air inlet end of the drying air duct 19.

[0175] If used damp cloths or cleaning brush heads and other accessories 20 are stored directly in the sealed accessory compartment 11, they will remain damp for a long time, becoming a breeding ground for mold and bacteria, producing odors and causing hygiene problems. By setting up a cleaning compartment 113 and connecting it to a drying air duct 19, the drying fan 40 can force air into the cleaning compartment 113, which can be room temperature air or heated air, to actively and quickly evaporate the residual moisture on the accessories 20, restoring them to a dry state. This eliminates the conditions for microbial growth, ensures the hygiene of the accessories 20 themselves, and prevents secondary pollution of the home environment during the next use.

[0176] Meanwhile, some accessories 20 may contain metal parts or electronic components, such as bearings, quick-release mechanisms 27, circuit boards, etc. A continuous humid environment will accelerate the corrosion of components and short circuits. By keeping accessories 20 dry, their service life can be effectively extended and their electrical safety can be ensured.

[0177] Furthermore, by directly integrating drying structures such as the drying fan 40 into the extension device 100, users no longer need to manually air-dry the accessories 20 or wait for them to air dry naturally. After cleaning and storage, the system automatically starts the drying program, allowing for direct use the next time it is needed, thus improving the user experience.

[0178] The expansion device 100 provided in this application embodiment includes a housing 10 and accessories 20. The housing 10 is connected to the base station of the self-cleaning device, and the housing 10 is provided with at least one accessory slot 11. The accessories 20 are detachably disposed in the corresponding accessory slot 11, and the accessories 20 are used to replace the robotic arm on the self-cleaning device to achieve different functions.

[0179] By providing at least one accessory slot 11 on the housing 10 and detachably placing accessories 20 into the corresponding slot 11, the robotic arm of the self-cleaning device can achieve multiple cleaning functions as needed by replacing different accessories 20. This flexibility allows the device to adapt to different cleaning tasks. Changing the robotic arm to different accessories 20 breaks through the single-function limitations of traditional sweepers and simply adding robotic arms. A single device can switch between multiple cleaning modes, expanding the functionality of the robotic arm and improving its utilization. The self-cleaning device can flexibly adjust according to different cleaning needs and environmental conditions, adapting to various usage scenarios, meeting the personalized needs of different users, and improving the user experience.

[0180] This application also provides a cleaning system, including a self-cleaning device, a base station, and the aforementioned extension device 100.

[0181] The foregoing can be better understood in accordance with the following terms:

[0182] Clause A1, an extension device for use in a self-cleaning device, said extension device comprising:
