Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0052] See Figures 1 to 8As shown, this application provides a steam module 200 for a sweeper. The steam module 200 for a sweeper includes an assembly shell 1000, a heat-conducting shell 2000, a heating element 3000, an electrode plate 4000, and an insulating structure 5000. The assembly shell 1000 has an assembly chamber 1010 inside for accommodating other components. The heat-conducting shell 2000 is assembled in the assembly chamber 1010 of the assembly shell 1000. The heat-conducting shell 2000 has a drainage channel 2100 and a receiving chamber 2200 inside. The heating element 3000 is assembled in the receiving chamber 2200 of the heat-conducting shell 2000. The heating element 3000 is configured to transfer heat through the heat-conducting shell 2000 to the drainage channel 2100, thereby heating the liquid flowing through the drainage channel 2100, causing the liquid to evaporate into steam. The steam can be used in the sweeper to clean areas of the floor awaiting cleaning.

[0053] Electrode 4000 is disposed on the surface of heating element 3000. Electrode 4000 provides electrical energy to heating element 3000 and allows current to pass through heating element 3000, causing heating element 3000 to heat up. Insulating structure 5000 is insulatingly covered on the outside of heating element 3000 and electrode 4000, and insulating structure 5000, electrode 4000, and heating element 3000 are assembled together in the receiving chamber 2200 of heat-conducting shell 2000.

[0054] Therefore, the heating element 3000 generates heat, which is transferred to the heat-conducting shell 2000, and then the heat-conducting shell 2000 transfers the heat to the liquid in the drainage channel 2100. When the liquid temperature reaches its boiling point, it begins to vaporize and generate steam. The steam is discharged through the outlet of the drainage channel 2100 and can be used for applications such as heating and steam ironing.

[0055] The design of the aforementioned steam module 200 ensures high heat transfer efficiency, rapid steam generation, and precise temperature control, making it suitable for various applications requiring steam and heat. The special design of the heat-conducting shell 2000 ensures both efficient heat transfer and safe operation, preventing hazards caused by high-temperature steam leakage.

[0056] In one embodiment, the heating element 3000 is configured as a PTC heating element 3000. The PTC heating element 3000 has self-limiting temperature characteristics; when the temperature rises to a certain level, its resistance increases sharply, thereby limiting the current flow and preventing overheating, thus improving the safety of the steam module 200. Two electrode plates 4000 are configured, each disposed on a different surface of the heating element 3000. These two electrode plates allow the current to flow evenly through the heating element 3000, improving heating efficiency and uniformity.

[0057] The flow channel 2100 and the assembly chamber 1010 are isolated from each other inside the heat-conducting shell 2000, and the flow channel 2100 is arranged around the assembly chamber 1010. This design is beneficial for the uniform distribution and conduction of heat. For example, the flow channel 2100 is designed with a meandering shape, which increases the contact area between the steam and the heat-conducting shell 2000 and improves the heat exchange efficiency. The inner wall of the flow channel 2100 is smoothly treated to reduce steam flow resistance and allow the steam to flow smoothly. The cross-section of the flow channel 2100 is elliptical, which has a larger contact area than a circular cross-section while maintaining hydrodynamic properties.

[0058] The drainage channel 2100 may include a drainage pipe and an inlet component 2110 and an outlet component 2120 disposed at both ends of the drainage pipe. The drainage pipe is configured as a heat-conducting metal material, and at least one of the inlet component 2110 and the outlet component 2120 is configured as a rubber material, which facilitates the connection of the inlet component 2110 and the outlet component 2120 to the clean water tank and the steam nozzle. Furthermore, the drainage pipe may be integrally formed with the heat-conducting shell 2000, or it may be a separate assembly structure, which is not limited here.

[0059] The receiving chamber 2200 is located at the center of the heat-conducting shell 2000 and has a recessed structure. Its depth matches the thickness of the heating element 3000, ensuring that the heating element 3000 can be fully embedded and in close contact with the heat-conducting shell 2000. In addition, the bottom of the receiving chamber 2200 has multiple tiny protrusions. These protrusions increase the contact area with the heating element 3000 and form tiny air channels to prevent deformation caused by thermal stress between the heating element 3000 and the heat-conducting shell 2000.

[0060] The heat-conducting shell 2000 is made of aluminum, which has excellent thermal conductivity, enabling rapid heat transfer and improved heating efficiency. Furthermore, aluminum has a high thermal conductivity and is relatively lightweight, facilitating a lightweight design for the overall device.

[0061] In one embodiment, the insulating structure 5000 is configured as an insulating film that insulatingly covers the exterior of the heating element 3000 and the electrode plate 4000. The insulating structure 5000 is configured to have an insulating cavity 5100 with an opening through which the heating element 3000 and the electrode plate 4000 are assembled. This design effectively prevents current leakage and ensures safe operation.

[0062] In one embodiment, the steam module 200 includes a retaining pad 6000 fitted into an insulating cavity 5100 of an insulating structure 5000. The surface of the retaining pad 6000 is provided with a limiting slope 6100, which gradually increases in elevation within the insulating cavity 5100 towards the cavity opening. A heating element 3000 and an electrode 4000 are disposed on the limiting slope 6100 of the retaining pad 6000, which is configured to prevent the heating element 3000 and the electrode 4000 from detaching from the insulating cavity 5100 through the cavity opening. This design enhances the stability of the assembly, preventing it from loosening or falling off during use due to vibration or other external forces.

[0063] In one embodiment, the steam module 200 includes a heat insulation structure 7000, which is fitted into the assembly chamber 1010 of the assembly shell 1000 and is heat-insulatingly disposed between the heat-conducting shell 2000 and the assembly shell 1000. The heat insulation structure 7000 is designed to effectively block heat transfer between the heat-conducting shell 2000 and the assembly shell 1000, preventing heat from being conducted from the heat-conducting shell 2000 to the assembly shell 1000, thereby maintaining the temperature stability of the assembly shell 1000.

[0064] In one embodiment, the thermal insulation structure 7000 includes two thermal insulation plates 7100, which are respectively disposed on two surfaces of the thermally conductive shell 2000. The two surfaces of the thermally conductive shell 2000 are thermally insulated from the two inner walls of the assembly chamber 1010 by the two thermal insulation plates 7100. The thermal insulation plates 7100 are made of a material with low thermal conductivity, which can effectively block the heat transfer path. For example, the thermal insulation structure 7000 is configured as thermal insulation cotton, and the thermal insulation plates 7100 are made of thermal insulation cotton in a plate-like structure. The thermal insulation cotton is made of a porous material containing a large number of tiny pores, which can effectively block the conduction of heat. The thermal insulation cotton fills the space between the thermally conductive shell 2000 and the inner wall of the assembly chamber 1010, forming a continuous and complete thermal insulation layer. The insulation cotton is lightweight and has good heat insulation effect. It can adapt to different shaped installation spaces, fill the irregular gaps between the heat-conducting shell 2000 and the inner wall of the assembly chamber 1010, and ensure the uniformity of the heat insulation effect.

[0065] The heat insulation plate 7100 is tightly fitted to the heat-conducting shell 2000, ensuring that the heat generated by the heat-conducting shell 2000 is not directly transferred to the inner wall of the assembly chamber 1010. Simultaneously, the heat insulation plate 7100 maintains good contact with the inner wall of the assembly chamber 1010, forming a complete heat insulation barrier. The heat insulation structure 7000 reduces heat transfer to the assembly shell 1000, improving heating efficiency and lowering the surface temperature of the assembly shell 1000, thus enhancing operational safety.

[0066] In one embodiment, the steam module 200 includes a temperature controller 8000 connected to the heat-conducting shell 2000 to acquire temperature data of the heat-conducting shell 2000, thereby enabling real-time monitoring of the temperature of the heat-conducting shell 2000. For example, the temperature controller 8000 can control the working state of the heating element 3000 according to set temperature parameters to achieve precise temperature control and avoid excessively high or low temperatures affecting the performance.

[0067] The temperature controller 8000 is electrically connected to the heating element 3000. It can control the operating state of the heating element 3000 and adjust its output power according to actual needs, thereby precisely controlling the temperature of the heat-conducting shell 2000. The temperature controller 8000 can have a built-in temperature sensor that can monitor the temperature changes of the heat-conducting shell 2000 in real time and automatically adjust the operating state of the heating element 3000 according to preset temperature parameters, achieving precise temperature control.

[0068] When the temperature controller 8000 is connected to the electrode plate 4000, the temperature controller 8000 can monitor the working status of the electrode plate 4000 and adjust the system's operating parameters according to the temperature changes of the electrode plate 4000, ensuring that the electrode plate 4000 operates within a suitable temperature range. The temperature controller 8000 adopts a closed-loop control principle, continuously adjusting the control parameters through a feedback mechanism to maintain the system temperature within the set range, thereby improving the system's stability and reliability.

[0069] In a preferred embodiment, the temperature controller 8000 is connected to both the heating element 3000 and the electrode plate 4000, forming a complete temperature control system. The temperature controller 8000 monitors the temperatures of the heating element 3000 and the electrode plate 4000 through multiple temperature acquisition channels, and controls them according to the temperature requirements of different components to ensure the entire system operates at optimal temperatures. The temperature controller 8000 also has over-temperature protection; when the temperature of any component exceeds a safe threshold, it automatically cuts off the power to the corresponding component to prevent system damage due to overheating.

[0070] Through the design of the aforementioned heat insulation structure 7000, an effective thermal insulation layer is formed between the heat-conducting shell 2000 and the assembly shell 1000, preventing the heat generated by the heat-conducting shell 2000 from being transferred to the assembly shell 1000, and protecting the assembly shell 1000 and its surrounding environment from high temperatures. Simultaneously, the application of the temperature controller 8000 ensures precise control of the system temperature, improving the overall efficiency and reliability of the device.

[0071] In one embodiment, the steam module 200 includes a temperature fuse 9000 connected in series in a series circuit of a temperature controller 8000, a heating element 3000, and an electrode 4000. The temperature fuse 9000 contains a fusible element made of a low-melting-point alloy, such as a heating wire. When the ambient temperature exceeds a preset threshold, the fusible element melts, causing the circuit to break, thereby cutting off the power supply between the temperature controller 8000, the heating element 3000, and the electrode 4000 connected to it, preventing equipment damage or fire hazard due to overheating.

[0072] The temperature fuse 9000 also includes connection terminals extending from the side of the housing 1000 for electrical connection to the temperature controller 8000, heating element 3000, or electrode plate 4000. The connection terminals are made of a highly conductive copper alloy with a tin-plated surface to prevent oxidation and corrosion, ensuring a long-term stable electrical connection.

[0073] In practical applications, the 9000 temperature fuse can be equipped with different melting points depending on the application scenario. When the temperature of the protected equipment is normal, the fuse remains solid, and the circuit remains conductive. When the temperature rises abnormally and reaches the melting point of the fuse, the fuse melts rapidly, breaking the circuit and cutting off the power supply to prevent damage to the equipment due to overheating. This protection mechanism is one-time use; after blowing, the 9000 temperature fuse needs to be replaced. This ensures the reliability of the protection and avoids the potential failure risk of resettable protection devices.

[0074] The temperature fuse 9000, when connected to the temperature controller 8000, provides additional safety in case the temperature control system fails; when connected to the heating element 3000, it cuts off the power supply when the heating element 3000 overheats abnormally; and when connected to the electrode plate 4000, it disconnects the circuit when the electrode plate 4000 experiences abnormal temperature. This multi-protection mechanism significantly improves the safety performance of the equipment.

[0075] In one embodiment, the assembly housing 1000 includes a first housing 1100 and a second housing 1200. The first housing 1100 has a first chamber inside, and the second housing 1200 has a second chamber inside. The first and second chambers are configured to form an assembly chamber 1010. This split design facilitates assembly and maintenance, while also enhancing structural stability.

[0076] The first housing 1100 may be made of a high-temperature resistant insulating material, such as ceramic or high-temperature engineering plastic, to ensure structural stability and insulation performance under high-temperature conditions. The upper part of the first housing 1100 has an opening for easy installation and maintenance of internal components. The second housing 1200 matches the first housing 1100 and is made of the same or compatible materials. The edge of the second housing 1200 has a sealing groove, which, when combined with the first housing 1100, forms a tight seal to prevent dust and moisture from the external environment from entering the assembly chamber 1010. The exterior of the second housing 1200 has mounting holes for easy fixing of the temperature fuse 9000 to the equipment requiring protection.

[0077] In one embodiment, the first housing 1100 and the second housing 1200 are connected by a snap-fit ​​structure for easy disassembly and maintenance. The snap-fit ​​structure includes a protrusion on the edge of the first housing 1100 and a corresponding groove on the second housing 1200, which engage tightly to ensure the overall stability of the assembled housing 1000.

[0078] This application provides a sweeping machine, which includes at least a chassis 100, a clean water tank, a steam nozzle, and the aforementioned steam module 200. The clean water tank is mounted on the chassis 100, and the steam nozzle is mounted on the chassis 100. Figure 1 As shown, the steam nozzle can be led out to the chassis 100 through the steam outlet 101; the inlet of the channel 2100 of the steam module 200 is connected to the clean water tank, and the outlet of the channel 2100 of the steam module 200 is connected to the steam nozzle. Therefore, water can be obtained through the clean water tank, and then heated into steam by the steam module 200 and sprayed out from the steam nozzle for cleaning the ground waiting area.

[0079] Therefore, by integrating the aforementioned steam module 200, this sweeper can achieve steam mopping function. Because it uses a small-sized, high-efficiency PTC heating element 3000 to replace the traditional heating tube, the steam module 200 can be more compactly integrated into the main unit of the sweeper, effectively reducing the overall size of the sweeper while ensuring the efficient realization of the steam mopping function.

[0080] The steam module 200 is mounted on the chassis 100 of the sweeper and is used for steam cleaning of the floor. In addition, the sweeper can also be equipped with a water tank, steam nozzles, and a control system. The water tank stores cleaning water, and the steam module 200 is connected to the water tank to heat the water into steam. The steam nozzles are located at the bottom of the sweeper and are used to spray steam onto the floor. The control system controls the operating status of the steam module 200 and the timing and intensity of the steam spray.

[0081] The water tank is designed with a detachable structure, making it convenient for users to add cleaning water and clean the tank. The water tank can be equipped with a water level indicator window, allowing users to intuitively understand the water level in the tank.

[0082] The steam nozzles can be designed in a fan shape and evenly distributed on the front bottom surface of the sweeper. Made of high-temperature resistant materials, the steam nozzles can withstand prolonged high-temperature operation without deformation. The steam nozzles are connected to the heating device via high-temperature resistant silicone tubing to ensure smooth steam delivery to the ground.

[0083] The control system includes a main control board and an operation panel. The operation panel is located on top of the sweeper and features a steam intensity adjustment button and indicator lights. Users can select between low, medium, and high steam intensity levels based on different floor materials and the degree of soiling. The main control board controls the heating device's power and steam injection frequency according to user settings.

[0084] During use, the working principle of the steam module 200 of the sweeper is as follows:

[0085] First, the user adds an appropriate amount of water to the water tank and then starts the robot vacuum's steam cleaning function. The control system activates the steam module 200, heating the water in the tank into high-temperature steam. The steam is then delivered through pipes to the steam nozzles and evenly sprayed onto the floor. The high-temperature steam effectively breaks down oil and stubborn stains on the floor, while also killing bacteria and eliminating mites. As the robot vacuum moves forward, the continuous steam spray, combined with the wiping action of the mop assembly, achieves a deep clean of the floor.

[0086] The robot vacuum's steam module 200 features a compact design, mounted on the chassis 100 without increasing the overall height of the vacuum, maintaining its excellent maneuverability. Working in conjunction with other cleaning components, the steam module 200 achieves a comprehensive four-in-one cleaning effect, combining sweeping, vacuuming, mopping, and steaming, significantly improving the efficiency and quality of household cleaning.
