Description

Technical Field

[0001] This utility model relates to the field of intelligent cleaning equipment technology, and more specifically, to a stable cleaning system. Background Technology

[0002] With the continuous improvement of people's living standards and the increasing demands for cleaning efficiency in their living and working environments, various automated and intelligent cleaning equipment has been widely used in the market. Among them, adsorption-type cleaning equipment, such as window cleaning robots, can move autonomously on vertical or inclined surfaces (such as glass curtain walls and windows) to complete cleaning tasks, greatly reducing the burden and risks of manual labor, and its market penetration rate has been increasing year by year.

[0003] Most mainstream adsorption cleaning devices on the market today are designed with their core functional units integrated inside the main body of the device. Specifically, the cleaning device typically houses an energy storage unit (such as a rechargeable battery), a control circuit board (e.g., a control circuit board integrating a microprocessor, sensor interfaces, etc.), and a water supply unit. The control circuit board is responsible for important functions such as processing sensor signals, planning movement paths, controlling motor actions, managing power distribution, and executing user commands.

[0004] However, this integrated design scheme, which highly integrates the power supply and control module into the device body, has gradually revealed many inherent technical defects and limitations in practical applications.

[0005] During cleaning operations, the liquid sprayed from the water tank onto the surface to be cleaned is then sucked into the cleaning equipment through an opening by the suction device. Because the contact space between the liquid and the internal control circuit boards, processors, and other electronic components is limited and lacks effective protection, the liquid can easily come into contact with these components, leading to a short circuit. A short circuit not only causes the cleaning equipment to malfunction and fail to operate normally, but in severe cases, it can even burn out the equipment, resulting in significant economic losses.

[0006] The built-in energy storage unit and relatively complex control circuitry and supporting structure significantly increase the weight and size of the cleaning equipment. This makes it inconvenient for users to handle and use, resulting in a poor user experience. Furthermore, the excessive weight forces the equipment to overcome greater gravity and friction when moving on vertical or inclined surfaces. This leads to several negative consequences: the motor needs to output more power to move the equipment, and prolonged high-load operation accelerates motor wear and reduces its lifespan. Overcoming greater resistance requires more electrical energy, increasing operating costs and contradicting energy conservation and environmental protection trends. Slower movement and difficulty in quickly responding to control commands affect cleaning efficiency and the completeness of path coverage. For example, cleaning corner areas may be incomplete due to the inflexible movement, impacting the user experience.

[0007] In summary, existing integrated designs for adsorption cleaning equipment suffer from the risk of short circuits and various drawbacks due to the weight and size of the equipment. Therefore, it is necessary to propose a more reliable, safer, and user-friendly cleaning system. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stable cleaning system, which places the power supply and control circuit board on an independent control host, and separates it from the cleaning equipment body through a traction line. This significantly improves the waterproof reliability of the control circuit board in wet cleaning environment and effectively reduces the weight of the cleaning equipment body, making it easier for users to use.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stable cleaning system includes a cleaning device and a control unit connected to the cleaning device via a traction line. The cleaning device has a walking mechanism, a negative pressure generator, and sensors. The control unit has: The control circuit board is electrically connected to the walking mechanism, the negative pressure generator, and the sensor, and controls the walking mechanism and / or the negative pressure generator based on the operating status information of the cleaning equipment obtained by the sensor. The power supply unit is electrically connected to the walking mechanism, the negative pressure generator, and the sensor; and A storage battery, electrically connected to the walking mechanism and the negative pressure generator, provides power to the walking mechanism and the negative pressure generator when the power supply device stops outputting power; The cleaning equipment and the control host are set up separately at a distance, and the two are connected by a traction line for power and signal transmission.

[0010] Furthermore, the length of the traction line is greater than 2m.

[0011] Furthermore, the traction line is a multi-core wire, which contains power transmission lines and data communication lines.

[0012] Furthermore, the connection end between the traction line and the control host and / or the cleaning equipment is a quick-plug mechanical connector.

[0013] Furthermore, the quick-connect mechanical connector is equipped with a waterproof structure.

[0014] Furthermore, the traction line is configured to be non-detachably fixedly connected to the connection end of the control host and / or the cleaning equipment.

[0015] Furthermore, the traction line has tensile reinforcement on its exterior, enabling it to function as a power supply line, a communication line, and a safe traction line for equipment.

[0016] Furthermore, the power supply device includes an adapter configured to convert alternating current (AC) into direct current (DC).

[0017] Furthermore, the control host includes a network communication device, and the control circuit board is connected to a cloud server or mobile terminal through the network communication device to receive remote control commands or upload the operating data of the cleaning equipment.

[0018] Furthermore, the cleaning system also includes a water supply device for wet cleaning, which is configured within the cleaning equipment or control unit.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects: The stable cleaning system provided by this invention effectively avoids the risk of short circuits caused by liquid being drawn into the cleaning equipment and contacting electronic components such as the control circuit board during wet cleaning operations. This is achieved by externalizing the power supply and control circuit board to a separate control unit, far removed from the cleaning equipment itself. Simultaneously, this separation design keeps the control circuit board away from environments where it may come into contact with liquids, significantly improving its waterproof reliability in wet cleaning scenarios. This ensures stable operation of the cleaning equipment, reduces equipment failure rates and damage risks, and minimizes economic losses.

[0020] This invention separates the power supply and control unit from the main body of the cleaning equipment, placing it in an independent control host, significantly reducing the weight and size of the cleaning equipment. This makes it easier for users to handle and use. Furthermore, the reduced weight means that the equipment needs to overcome significantly less gravity and friction when moving on vertical or inclined surfaces. The motor requires less power to move the equipment flexibly, effectively reducing motor wear and extending its lifespan. Simultaneously, energy consumption is reduced, lowering operating costs and aligning with energy conservation and environmental protection trends. Moreover, the equipment moves more quickly and flexibly, responding rapidly to control commands, improving cleaning efficiency, and ensuring complete path coverage, especially when cleaning corner areas, greatly enhancing the user experience.

[0021] The control unit and cleaning equipment are connected via a long traction cable (e.g., greater than 2 meters), allowing users to operate and maintain the control unit in a safe and convenient location away from the cleaning work surface (e.g., near windows), improving ease of use and safety. The control unit's built-in network communication module enables remote control, status monitoring, and data uploading via a cloud server or mobile terminal, achieving intelligent management of cleaning operations. Furthermore, the traction cable integrates power supply, communication, and safety traction functions, along with a collaborative design between the power supply device and the battery (powering and charging under normal conditions, with backup in case of abnormalities), ensuring continuous and stable operation of the system under various working conditions and expanding its application scenarios.

[0029] Example 1: This embodiment provides a stable cleaning system, which mainly includes a cleaning device 100 and a control host 200, connected by a traction cable 300 of a certain length. The cleaning device 100 can be a window cleaning robot, etc., used to move and perform cleaning tasks on vertical or inclined surfaces (such as glass windows, tiled walls, and glass curtain walls). The control host 200 is a box-like structure independent of the cleaning device 100, typically placed on the ground, a table, or other safe and stable location.

[0030] The cleaning device 100 includes a housing, a walking mechanism 110, a negative pressure generator 120, sensors 130, and cleaning execution components (not shown in detail in the figure, such as cleaning cloths, squeegees, and spray nozzles). The walking mechanism 110 typically includes a drive motor and wheels / tracks, responsible for driving the device to move across the surface to be cleaned. The negative pressure generator 120, such as a turbine fan or vacuum pump, generates a negative pressure adsorption force between the cleaning device 100 and the surface to be cleaned, allowing it to adhere firmly to a vertical or inclined surface. The sensors 130 may include, but are not limited to, position sensors (such as encoders), attitude sensors (such as gyroscopes and accelerometers), distance sensors (such as infrared and ultrasonic sensors), pressure sensors, and collision sensors, used to detect the operating status, position, attitude, and environmental information of the cleaning device 100 in real time.

[0031] The control host 200 integrates a control circuit board 210, a power supply device 220, and a storage battery 230.

[0032] The control circuit board 210 is the core of the system's control, typically a printed circuit board integrating a microprocessor (MCU), memory, drive circuit, signal conditioning circuit, and communication interface. The control circuit board 210 establishes a bidirectional signal connection with the sensors 130 on the cleaning equipment 100 via the data communication line within the traction line 300, receiving real-time operating status information from each sensor. Simultaneously, the control circuit board 210 also sends control commands to the drive motor of the walking mechanism 110 and the motor of the negative pressure generator 120 of the cleaning equipment 100 via the traction line 300, precisely controlling their start / stop, speed, and direction, thereby achieving intelligent control of the cleaning equipment 100's movement path, speed, and suction force. Based on information fed back from the sensors 130 (such as obstacle detection signals, edge signals, and position information), the control circuit board 210 can dynamically adjust its control strategy, achieving functions such as automatic cleaning path planning, obstacle avoidance, edge detection and processing, etc.

[0033] The power supply device 220 includes an AC to DC adapter (power adapter) that converts AC power to DC power. Its input is connected to AC mains power, and its output provides a stable DC operating voltage. The output of the power supply device 220, through the power transmission line within the traction line 300, provides operating power to all power-consuming units on the cleaning equipment 100, including the motor of the walking mechanism 110, the motor of the negative pressure generator 120, and the sensor 130. Simultaneously, when the power supply device 220 is operating normally, the control circuit board 210 also controls it to charge the battery 230, keeping the battery 230 fully charged or in a standby state with a set charge level.

[0034] Battery 230 serves as a backup power source. Its positive and negative terminals are connected to the power management module of control circuit board 210 and the power consumption unit of cleaning equipment 100 through corresponding circuits. Under normal operating conditions, the system is powered by power supply device 220. In case of unexpected situations, such as a sudden power outage or a failure of power supply device 220, control circuit board 210 can quickly detect the main power outage and seamlessly (or after a very short delay) switch to battery 230 to power the walking mechanism 110 and negative pressure generator 120 of cleaning equipment 100. This ensures that even if the external power supply is interrupted, cleaning equipment 100 can still maintain sufficient suction force and basic mobility, enabling it to execute safe shutdown procedures (e.g., move to the nearest safe recycling point) or maintain its suction state to avoid falling, greatly improving the safety and reliability of the system.

[0035] The control host 200 also includes a network communication device 240. This device can be a wired network device (such as an Ethernet interface) or a wireless communication device, such as a Wi-Fi module, Bluetooth device, or 4G / 5G cellular network device. The control circuit board 210 establishes a connection with a cloud server or a user's mobile terminal (such as a smartphone or tablet) via the network communication device 240. Remote control functionality is then enabled: users can install a dedicated APP on their mobile terminal. Through the APP, users can remotely start or stop the cleaning system, set cleaning plans, select cleaning modes (such as spot cleaning, area cleaning, and global cleaning), and even view real-time images transmitted from the cleaning equipment 100's camera (if equipped). The control circuit board 210 receives these remote control commands via the network communication device 240 and forwards them to the cleaning equipment 100 for execution. Simultaneously, the control circuit board 210 also uploads the operating data of the cleaning equipment 100 (such as working time, cleaning area, energy consumption, sensor readings, fault alarm information, etc.) to the cloud server for storage and analysis via the network communication device 240. Users can view historical cleaning records and equipment health status through the APP. The cloud server can also provide users with optimization suggestions based on big data analysis, such as suggested cleaning paths and predicted maintenance times. This embodiment, by introducing intelligent power management and network communication functions, greatly enhances the intelligence level of the cleaning system and the user experience, achieving safe, efficient, and convenient remote management and maintenance.

[0036] The cleaning system also includes a water supply device 140, which can be configured within the cleaning equipment 100 or the control host 200. In this embodiment, the water supply device 140 is configured inside the cleaning equipment 100. The water supply device 140 includes a water tank, a micro water pump, a water level sensor, and a spray nozzle / wetting mechanism integrated within the housing of the cleaning equipment 100. The control circuit board 210 sends commands to the water supply device 140 via control lines within the traction line 300 to control its on / off state and flow rate. Integrating the water supply device 140 inside the cleaning equipment 100 has unique advantages: First, it minimizes the water supply path, reduces response delay, and makes spray control more precise and timely; second, the physical location of the water supply system and cleaning execution components (such as squeegees and cleaning cloths) is closer, facilitating integrated design and coordinated control, and optimizing cleaning results; third, it avoids the risks of blockage, bends, aging, and leakage that may occur with long-distance water pipelines.

[0037] The traction cable 300 is configured to connect the control host 200 and the cleaning equipment 100. In this embodiment, its length is designed to be greater than 2 meters, such as 3 meters, 5 meters, or longer. This allows the control host 200 to be placed in a safe indoor location away from the cleaning work surface (such as a window), while the cleaning equipment 100 can operate outside the window or on a high glass surface. This avoids the risks to the control host caused by water splashes, sun exposure, or placement at height, and also facilitates user operation and observation. The traction cable 300 is a multi-core cable, internally integrating at least two power transmission lines (such as positive and negative terminals) and multiple data communication lines (such as CAN bus, UART serial port, differential signal lines, etc.) to achieve bidirectional transmission of power and control / sensor signals. The traction cable 300 itself should have a certain tensile strength and flexibility.

[0038] In a preferred embodiment, the two ends of the traction line 300 (the connection ends with the control host 200 and the cleaning equipment 100) can be fixedly connected in a non-detachable manner. For example, the core of the traction line 300 can be directly welded or sealed and fixed to the control circuit board 210 and power interface inside the control host 200, and the corresponding interface board inside the cleaning equipment 100, through a special waterproof connector. This method provides reliable connection and good sealing, effectively preventing poor contact or water ingress caused by frequent plugging and unplugging. To enhance safety, tensile reinforcement components, such as aramid fibers and steel wires, can also be integrated inside the traction line 300. This allows the traction line 300 to not only provide power supply and communication functions, but also act as a safety rope in emergency situations (such as when the cleaning equipment unexpectedly loses pressure but does not completely detach), bearing a certain amount of tension to prevent the equipment from falling directly, thus combining the functions of power supply, communication, and safe traction of the equipment. A hook 310 is fixed to the end of the traction line 300 away from the cleaning equipment 100. The hook 310 can be attached to a fixed device to hold the falling cleaning equipment and prevent the cleaning equipment 100 from falling from a height and being damaged or causing a safety accident.

[0039] In another embodiment, the connection points of the traction cable 300 with the control host 200 and the cleaning device 100 employ quick-plug mechanical connectors. Specifically, male and female electrical connectors are provided at both ends of the traction cable 300, on the housing of the control host 200, and on the housing of the cleaning device 100. This design greatly facilitates the assembly, transportation, storage, and maintenance of the system. For example, when not in use or during long-distance transportation, the traction cable 300 can be disconnected from both ends and stored separately, reducing volume and preventing cable tangling. It is also more convenient to replace traction cables of different lengths to adapt to different operating scenarios (such as ordinary household windows and large glass curtain walls).

[0040] Considering that the cleaning system may be used in humid environments or outdoors (such as in light rain when cleaning balcony windows), the quick-connect mechanical connector is specially designed with a waterproof structure. This waterproof structure may include: a sealing ring (such as an O-ring) on ​​the connector mating surface, a threaded locking structure on the connector housing (tightening the housing after mating to achieve a seal), or the use of a standard waterproof connector that meets a specific waterproof rating (such as IPX4 splash resistance or IPX7 short-term immersion resistance). This effectively prevents moisture or liquid from entering the device from the connector, further enhancing the system's environmental adaptability and reliability.

[0041] In this embodiment, the traction wire 300 has a tensile reinforcement on the outside. At the joint, the tensile reinforcement (such as aramid yarn) is fixed inside the joint housing by a special stress relief structure (such as a pressure plate or clip), ensuring that the tensile force is mainly borne by the reinforcement and the joint housing, rather than acting on the thin wires and terminals, thus ensuring the reliability of the electrical connection.

[0042] The system's workflow is as follows: 1. Start-up and Normal Power Supply: Connect the control host 200 to mains power. The user starts the system via the physical buttons on the control host 200 or the paired mobile terminal APP. After the control circuit board 210 completes its self-test, it first controls the power supply device 220 to work, converting the mains power into suitable DC power and supplying power to the cleaning equipment 100 through the traction cable 300. At the same time, the power output from the power supply device 220 also charges the battery 230. After the cleaning equipment 100 is powered on, the control circuit board 210 controls its negative pressure generator 120 to work, causing it to adhere to the glass surface, and then controls the walking mechanism 110 to begin cleaning operations according to a preset or planned path. During this period, the control circuit board 210 continuously monitors the working status of the power supply device 220.

[0043] 2. Abnormal Switching and Backup Power Supply: If a power outage occurs during the cleaning process or the power supply device 220 malfunctions, the control circuit board 210 will quickly detect the power supply anomaly (e.g., by monitoring whether the output voltage of the power supply device 220 disappears or drops below a threshold). The control circuit board 210 will immediately act to cut off the power supply path of the power supply device 220 and simultaneously connect the power supply path of the storage battery 230. The electrical energy stored in the storage battery 230 will continue to power the cleaning equipment 100 through the traction cable 300, maintaining the vacuum fan of the negative pressure generator 120 for a short period (e.g., enough to maintain 20 to 30 minutes), allowing the cleaning equipment 100 to remain in the adsorption state, or controlling the walking mechanism 110 to move the equipment to a safe position (such as the edge of a window frame), thereby effectively preventing the cleaning equipment 100 from falling from a height due to a momentary power outage, greatly improving safety. After the mains power is restored, the control circuit board 210 will automatically switch back to power supply from the power supply device 220 and replenish the storage battery 230.

[0044] 3. Communication and Monitoring: Throughout the process, the control circuit board 210 and the cleaning equipment 100 maintain real-time communication via the data communication line within the traction cable 300. The cleaning equipment 100 sends sensor data to the control circuit board 210, which then makes intelligent decisions (such as obstacle avoidance and path adjustment). Simultaneously, the control circuit board 210 can upload the operating status of the cleaning equipment 100 (such as current location, battery level, and fault codes) to a cloud server or the user's mobile terminal via a network communication unit that may be integrated into the control host 200, enabling remote monitoring.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
