Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for cleaning equipment, and specifically to a cleaning device. Background Technology

[0002] With the iterative updates and development of technology, cleaning equipment, especially self-propelled cleaning equipment, is becoming increasingly widely used and is gradually becoming popular both domestically and internationally. As cleaning equipment becomes more intelligent, the number of electronic components on it is also continuously increasing. These electronic components and batteries generate a lot of heat during operation or charging, posing a significant challenge to the heat dissipation of the cleaning equipment. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a cleaning device to improve the problem that the heat generated by the existing cleaning device accumulates inside, which easily triggers high temperature alarms, and easily leads to reduced efficiency or safety risks.

[0004] To achieve the above and other related objectives, this utility model provides a cleaning device, including a cleaning element, a heating element, and a heat dissipation element. The cleaning element is configured to interfere with the surface to be cleaned to clean it; when the heating element operates, at least a portion of its electrical or mechanical energy is converted into heat energy; a heat dissipation element is disposed at the heating element, and the heat dissipation element includes a heat sink and a heat-conducting component, wherein the thermal conductivity of the heat-conducting component is greater than or equal to the thermal conductivity of the heat sink, and the heat-conducting component is configured to absorb heat from the heat sink and / or the heating element.

[0005] By incorporating heat dissipation elements at the heating elements, the heat generated by the heating elements is transferred to the heat dissipation elements via one or more heat transfer mechanisms, including thermal radiation, thermal conduction, and thermal convection. The heat sink and heat-conducting components have a large heat dissipation area, improving the heat dissipation efficiency of the heating elements. The heat conduction coefficient of the heat-conducting components is greater than that of the heat sink, allowing the heat to be dissipated from the heat sink and / or heating elements more quickly, preventing heat accumulation at the heating elements, reducing the temperature at the heating elements, lowering high-temperature alarms and safety risks, and ensuring the efficient operation of the cleaning equipment.

[0006] In an exemplary embodiment of the present invention, the cleaning device includes a metal counterweight, and the heat-conducting component and / or heat sink is at least partially attached to the metal counterweight.

[0007] Metal counterweights balance the cleaning equipment, especially for equipment with heavy components such as water tanks and batteries. They ensure greater stability during operation, preventing tipping or shaking and improving operational stability. Metal counterweights also control the inertial forces and vibrations of the cleaning equipment, allowing for smooth operation. Metal counterweights can be made of cast iron or aluminum, with cast iron being preferred to reduce costs. By attaching at least a portion of the heat-conducting component and / or heat sink to the metal counterweight, heat conduction occurs between them, facilitating heat dissipation and reducing heat buildup at the heat dissipation element, thus lowering its temperature. Meanwhile, the metal counterweight itself has a large surface area and good thermal conductivity, which allows the heat from the heat-conducting and / or heat-dissipating components to be quickly conducted out and transferred through the surface of the metal counterweight via thermal radiation and convection. This effectively improves heat dissipation capacity, reduces the temperature of the heat-conducting and / or heat-dissipating components, thereby reducing the temperature at the heat-generating element, reducing high-temperature alarms and safety risks, and ensuring efficiency.

[0008] In an exemplary embodiment of this utility model, the heating element includes a main control board, a first heat sink is disposed on the main control board, a first heat conduction element is attached to the first heat sink, and the end of the first heat conduction element away from the heat sink is attached to the metal counterweight.

[0009] The main control board generates a significant amount of heat during operation, especially for some boards integrating fast charging modules, where even more heat is generated during fast charging. By installing a first heat sink on the main control board, this heat can be effectively dissipated, reducing its temperature. A first heat-conducting component then transfers the heat from the heat sink to a metal counterweight, preventing heat buildup on the main control board, reducing safety risks, and ensuring stable operation.

[0010] In an exemplary embodiment of the present invention, the heating element includes a battery, and a second heat-conducting element is provided on the battery, with one end of the second heat-conducting element away from the battery being attached to the metal counterweight.

[0011] Batteries generate significant heat during use and charging, especially fast-charging batteries. By incorporating a second heat-conducting component on the battery surface, this heat can be transferred to a metal counterweight, effectively mitigating surface temperature rise, ensuring continuous operation of the cleaning equipment, and shortening charging time. Maintaining battery temperature rise within a reasonable range meets safety requirements and enhances the market competitiveness of the cleaning equipment.

[0012] In an exemplary embodiment of the present invention, a second heat sink is attached to the battery, and the second heat sink is attached to the second heat-conducting component.

[0013] By attaching a second heat sink to the surface of the battery, the heat from the battery surface is transferred to the second heat sink via thermal radiation and thermal conduction, and then transferred to the metal counterweight via the second heat conductor. This effectively slows down the temperature rise of the battery surface, shortens the charging time, and ensures the continuous use of the cleaning equipment.

[0014] In an exemplary embodiment of this utility model, a third heat dissipation plate is attached to the metal counterweight, and the third heat dissipation plate is disposed between the heat-conducting component and the metal counterweight.

[0015] To reduce costs, metal counterweights are typically made of cast iron. However, the rough surface of cast iron affects the adhesion between the counterweight and the heat-conducting components. By attaching a third heat sink to the metal counterweight, the larger surface area of ​​the third heat sink increases the contact area with the metal counterweight, improving the heat transfer efficiency from the heat-conducting components to the metal counterweight. This effectively reduces heat buildup at the heating element, slows down the temperature rise at the heating element, and keeps the temperature at the heating element within a controllable range, meeting safety requirements and ensuring operational efficiency.

[0016] In an exemplary embodiment of the present invention, the cleaning device includes a container and a fluid pipeline. The container is connected to the cleaning element; the fluid pipeline is connected to the metal counterweight and / or heat dissipation element, and at least one end of the fluid pipeline is connected to the container.

[0017] The container is used to hold liquids. Because liquids such as water have a high specific heat capacity, they can absorb a large amount of heat. The liquid flows through the fluid tube and is connected to a metal counterweight and / or heat dissipation element. The liquid absorbs heat from the metal counterweight and / or heat dissipation element, thereby reducing the temperature of the heat dissipation element by lowering the temperature of the counterweight, and / or directly reducing the temperature of the heat dissipation element to lower the temperature of the heat dissipation element. This effectively slows down the temperature rise of the heat dissipation element, keeping the temperature of the heat dissipation element within a controllable range, meeting safety requirements, and improving the safety of the cleaning equipment.

[0018] In an exemplary embodiment of the present invention, the cleaning device includes a water inlet configured to be connected to a water path of a base station to inject liquid into the container; one end of the fluid pipeline is connected to the water inlet, and the other end is connected to the container.

[0019] Heat-generating components, such as batteries or their charging circuits, generate a significant amount of heat in a short period during fast charging, causing noticeable localized temperature increases, posing safety risks, and reducing charging speed. During charging, the cleaning equipment can simultaneously inject water into the container through a liquid pipeline from the water inlet. The liquid flows over a metal counterweight and / or heat dissipation elements, directly and / or indirectly reducing the temperature of the heat dissipation elements, slowing down the temperature rise at the heat-generating components, and keeping the temperature at the heat-generating elements within a controllable range, effectively ensuring charging efficiency. By utilizing the container's water replenishment pipeline, minimal modifications are required to existing cleaning equipment, facilitating upgrades; no additional water pumps or other components are needed, reducing costs and enhancing the product's competitiveness.

[0020] In an exemplary embodiment of this invention, the cleaning device includes an overflow pipe. One end of the overflow pipe is connected to the container, and the other end is configured to connect to the drainage system of a base station to drain excess liquid from the container. The overflow pipe connects to the base station's drainage system. When the liquid level in the container exceeds a preset threshold or other conditions require drainage, the water in the container is drained through the overflow pipe. This prevents excessive liquid in the container and, in special circumstances, maintains the fluidity of the liquid within the pipe, ensuring a cooling effect.

[0021] In an exemplary embodiment of this utility model, the heating element includes a charging circuit. When the charging circuit is connected to the circuit of the base station and charges the battery of the cleaning device, the base station continuously injects liquid into the container through the water inlet and the fluid pipeline.

[0022] When the charging circuit is connected to the base station circuit and charges the battery of the cleaning equipment, the charging circuit will generate a lot of heat. At this time, by injecting liquid into the container through the fluid pipeline, the heat-generating components such as the charging circuit can be effectively dissipated.

[0023] Currently, cleaning equipment has relatively small batteries due to size and weight constraints, resulting in limited energy storage and insufficient battery life. Taking robotic vacuum cleaners as an example, some robotic vacuum cleaners need to return to the base station to clean the mop during cleaning. While cleaning the mop, the battery is charged, and at the same time, liquid is injected into the container through the fluid pipeline. This not only dissipates heat from the charging circuit and replenishes the container, but also ensures the robotic vacuum cleaner's battery life, achieving multiple benefits.

[0024] In an exemplary embodiment of the present invention, the metal counterweight has an installation channel, at least a portion of the fluid pipeline is accommodated in the installation channel, and the fluid pipeline is in contact with the inner wall of at least a portion of the installation channel.

[0025] The fluid pipeline fits snugly against the mounting channel inside the metal counterweight, which improves the stability of the fit between the fluid pipeline and the metal counterweight, increases the contact area between the fluid pipeline and the metal counterweight, improves the heat dissipation efficiency of the metal counterweight, and thus effectively improves the heat dissipation efficiency at the heat-generating element.

[0026] In an exemplary embodiment of this utility model, the mounting channel extends through the metal counterweight; the metal counterweight includes an even number of mounting channels extending through it.

[0027] The installation channels pass through the metal counterweight, facilitating the flow of fluid lines and simplifying their installation. The water inlet and container of the cleaning equipment are typically located on the same side of the equipment, and less frequently on the opposite side. The use of even numbers of installation channels allows for bending of the fluid lines, maximizing the use of existing fluid line space on the cleaning equipment, simplifying spatial layout, and reducing costs.

[0028] In an exemplary embodiment of this utility model, both ends of the fluid pipeline are connected to the container.

[0029] The fluid pipeline and the liquid in the container circulate, thereby removing heat from the metal counterweight and / or heat dissipation element, slowing down the temperature rise of the heating element, ensuring the efficiency of the heating element, and improving the safety of the cleaning equipment.

[0030] In an exemplary embodiment of the present invention, the cleaning device includes a water pump disposed on the fluid pipeline and configured to circulate liquid within the fluid pipeline and the container.

[0031] The water pump enables the fluid to circulate in the circulation path formed by the fluid pipeline and the container. As the fluid flows through the fluid pipeline in contact with the metal counterweight and / or heat dissipation element, heat exchange occurs, thereby absorbing the heat from the metal counterweight and / or heat dissipation element. In subsequent circulation, the fluid exchanges heat with the water in the container that has not undergone heat exchange, thus reducing its temperature. This cycle is repeated to cool down the metal counterweight and / or heat dissipation element, effectively slowing down the temperature rise at the heating element and keeping its temperature within a controllable range.

[0032] In an exemplary embodiment of the present invention, the cleaning device includes a container and a fluid conduit, the container being connected to the cleaning element; the fluid conduit being connected to the heating element, and at least one end of the fluid conduit being connected to the container.

[0033] The container is used to hold liquid, and the fluid pipeline is connected to the heating element. The fluid flowing through the fluid pipeline can absorb the heat of the heating element, so as to slow down the temperature rise at the heating element and keep the temperature at the heating element within a controllable range to meet safety requirements and improve the safety of the cleaning equipment.

[0034] In an exemplary embodiment of the present invention, the cleaning device includes a water inlet configured to inject liquid into the container; one end of the fluid conduit is connected to the water inlet, and the other end is connected to the container.

[0035] The cleaning equipment injects water into the container through a liquid pipeline from the water inlet. The liquid flows over the heating element, slowing down the temperature rise and keeping the temperature of the heating element within a controllable range, effectively ensuring charging efficiency. By utilizing the container's water supply pipeline, minimal modifications are required to existing cleaning equipment, facilitating upgrades; no additional components such as water pumps are needed, reducing costs and enhancing the competitiveness of the cleaning equipment product.

[0036] In an exemplary embodiment of the present invention, the cleaning device includes a water pump disposed on the fluid pipeline; both ends of the fluid pipeline are connected to the container, and the water pump is configured to circulate the liquid in the fluid pipeline and the container.

[0037] The water pump enables the fluid to circulate in the circulation path formed by the fluid pipeline and the container. As the liquid flows through the fluid pipeline that is in contact with the heating element, heat exchange occurs. In the subsequent circulation, it exchanges heat with the water in the container that has not undergone heat exchange, thereby reducing the temperature. This cycle achieves cooling and heat dissipation at the heating element, effectively slowing down the temperature rise at the heating element and keeping the temperature of the heating element within a controllable range.

[0038] In combination with existing technologies, the beneficial effects of this utility model are as follows:

[0039] Existing heating elements generate heat that accumulates at the heating element itself, leading to high temperatures, triggering high-temperature alarms, reducing efficiency, and compromising safety. This invention addresses this by incorporating a heat dissipation element at the heating element. This allows heat generated by the heating element to be transferred to the heat dissipation element via one or more heat transfer methods, including thermal radiation, thermal conduction, and thermal convection. The heat sink and heat-conducting component have a large heat dissipation area, improving the heat dissipation efficiency of the heating element. The heat-conducting component has a higher thermal conductivity than the heat sink, allowing it to conduct heat away from the heat sink and / or heating element more quickly, preventing heat accumulation at the heating element, reducing high-temperature alarms and safety risks, ensuring the cleaning equipment's operational efficiency, and improving its safety.

[0057] Please see Figures 1 to 6 This application provides a cleaning device 1, which can be a mopping robot, a sweeping and mopping robot, or other cleaning robots that meet the requirements.

[0058] Please see Figure 1 The cleaning equipment 1 includes, but is not limited to, the equipment body 100, a cleaning system, and a drive system. These systems coordinate with each other to enable the cleaning equipment 1 to move autonomously and perform its cleaning function. The functional components constituting these systems are integrated within the equipment body 100. It is understood that the cleaning equipment 1 can be a self-moving cleaning equipment, which is a device capable of automatically performing cleaning operations in a designated area without user intervention.

[0059] The main body 100 of the device includes a front part and a rear part, and has an approximately circular shape or other shapes, including but not limited to an approximately D-shaped shape with a front and rear circle, and a rectangular or square shape with a front and rear.

[0060] Please see Figures 1 to 6 The cleaning device 1 provided by this utility model includes a cleaning element, a heating element 200, and a heat dissipation element 300. The cleaning element is configured to interfere with the surface to be cleaned to clean the surface; when the heating element 200 is working, at least a portion of its electrical or mechanical energy is converted into heat energy; the heat dissipation element 300 is disposed at the heating element 200, and the heat dissipation element 300 includes a heat sink 310 and a heat conductor 320, wherein the thermal conductivity coefficient of the heat conductor 320 is greater than or equal to the thermal conductivity of the heat sink 310, and the heat conductor 320 is configured to absorb the heat from the heat sink 310 and / or the heating element 200.

[0061] The cleaning system of cleaning device 1 may include a dry cleaning system, which includes the aforementioned cleaning elements. These cleaning elements can interact with the surface to be cleaned to clean it. For example, the cleaning elements may include a roller brush, and the cleaning system includes a dustbin and a vacuum fan. The roller brush, interacting with the ground, carries dust, particles, and other debris from the ground to the suction port between the roller brush and the dustbin. The debris is then drawn into the dustbin by the suction gas generated by the vacuum fan and passing through the dustbin. Furthermore, the cleaning system may also include a side brush assembly, rotatably connected to the device body 100, for moving debris and other contaminants outside the roller brush area to the roller brush area of ​​the cleaning system. For example, cleaning device 1 may be a robotic vacuum cleaner.

[0062] The cleaning system may include a wet cleaning system, which includes the aforementioned cleaning elements. The cleaning elements are capable of interfering with the surface to be cleaned to achieve wet cleaning of the surface. For example, the cleaning device 1 may be a mopping robot.

[0063] The cleaning device 1 may also include both a dry cleaning system and a wet cleaning system. For example, the cleaning device 1 may be a sweeping and mopping machine.

[0064] The heating element 200 can be any component that generates heat during operation. For example, the cleaning device 1 also includes an energy system, which includes a battery 220, such as a nickel-metal hydride battery 220 or a lithium battery 220. During charging and discharging, some electrical energy in the battery 220 is converted into heat, causing its temperature to rise. For instance, the energy system also includes a charging control circuit, which can be integrated into the main control board 210 of the cleaning device 1 or installed separately on the main body 100. The charging control circuit connects to an external power source and the battery 220 to charge the battery 220. During the charging process of the battery 220, some electrical energy is converted into heat, causing the charging control circuit to overheat, potentially triggering a high-temperature alarm, affecting the charging efficiency of the battery 220, or compromising charging safety. Especially with the development of battery 220 technology, fast charging is becoming increasingly widespread. During fast charging, the battery 220 can complete most of its charging in a short time, such as a few minutes or tens of minutes. This generates a significant amount of heat in the charging control circuit during fast charging. If this heat cannot be dissipated in time, the charging control circuit will rapidly heat up, which can range from affecting charging efficiency and reducing charging speed to triggering high-temperature alarms and even causing more serious risks such as circuit damage. For example, the cleaning device 1 also includes a main control board 210, which controls the movement of the cleaning device 1. During operation, some electrical energy is converted into heat energy, which can easily cause the temperature of the main control board 210 to rise, affecting its processing efficiency and the usability of the cleaning device 1.

[0065] It is understandable that the cleaning device 1 also includes electrical components, such as a drive unit, a sensing element, etc. The battery 220 is connected to the electrical components of the cleaning device 1 through a circuit to provide power to the electrical components.

[0066] It is understandable that the heating element 200 can also be other components. For example, the cleaning device 1 includes a drive unit for driving the cleaning element to work. The drive unit can be a motor. The motor will also generate heat during operation, so the heating element 200 can also be a motor, etc.

[0067] Please see Figure 2 and Figure 3The heat dissipation element 300 is disposed at the heating element 200. The heat dissipation element 300 can be in close contact with the heating element 200, or there can be a certain gap between them. Alternatively, it can be partially in close contact with the heating element 200 with a certain gap between the two. The relative positions of the heat dissipation element 300 and the heating element 200 can also be set according to actual needs. For example, if the heating element 200 is a battery 220, the heat dissipation element 300 can be in close contact with the surface of the battery 220; if the heating element 200 is the main control board 210, there can be a certain gap between the heat dissipation element 300 and the main control board 210. By setting the heat dissipation element 300 at the heating element 200, the heat generated by the heating element 200 is transferred to the heat dissipation element 300 through one or more heat transfer methods such as thermal radiation, thermal conduction, and thermal convection. The heat dissipation plate 310 and the heat-conducting component 320 have a large heat dissipation area, improving the heat dissipation efficiency of the heating element 200, slowing down the temperature rise rate at the heating element 200, and controlling the temperature at the heating element 200 within a controllable range.

[0068] The heat conduction system of the heat-conducting component 320 is greater than the heat conduction coefficient of the heat sink 310. For example, the heat sink 310 is an aluminum plate, and the heat conduction component 320 is a copper component, copper pipe, etc.; or, the heat sink 310 is a copper plate, and the heat conduction component 320 is a copper component, copper pipe, etc.; or, the heat sink 310 is an aluminum plate, and the heat conduction component 320 is an aluminum component, aluminum block, etc. Of course, the heat sink 310 and the heat conduction component 320 can also be made of other materials so that the heat conduction component 320 can absorb the heat from the heat sink 310 and / or the heating element 200 more quickly and conduct it out more quickly, avoiding the accumulation of heat at the heating element 200, reducing the temperature at the heating element 200, reducing high temperature alarms and safety risks, and ensuring the efficiency of the cleaning equipment 1.

[0069] Please see Figures 2 to 4 In one embodiment, the cleaning device 1 includes a metal counterweight 400, and the heat-conducting element 320 and / or the heat dissipation plate 310 are at least partially attached to the metal counterweight 400. The attachment method between the metal counterweight 400 and the heat dissipation element 300 can be that the heat-conducting element 320 is attached to the metal counterweight 400, the heat dissipation plate 310 is attached to the metal counterweight 400, or both the heat-conducting element 320 and the heat dissipation element are attached to the metal counterweight 400.

[0070] A metal counterweight 400 is mounted on the main body 100 of the equipment to balance the body of the cleaning equipment 1. Especially for cleaning equipment 1 with heavier components such as a water tank and battery 220, the metal counterweight 400 ensures greater stability during use, preventing tipping or shaking, thus improving operational stability. The metal counterweight 400 also controls the inertial force and vibration of the cleaning equipment 1, allowing it to operate smoothly. The metal counterweight 400 can be made of cast iron, aluminum, etc., with cast iron being preferred to reduce costs. By attaching at least a portion of the heat-conducting element 320 and / or the heat sink 310 to the metal counterweight 400, heat conduction occurs between the heat-conducting element 320 and / or the heat sink 310 and the metal counterweight 400, facilitating the dissipation of heat from the heat-conducting element 320 and / or the heat sink 310, thereby reducing heat accumulation at the heat dissipation element 300 and lowering its temperature. Meanwhile, the metal counterweight 400 has a large surface area and good thermal conductivity, which allows the heat from the heat-conducting component 320 and / or the heat sink to be quickly conducted out and transferred through the surface of the metal counterweight 400 via thermal radiation and convection. This effectively improves heat dissipation capacity, reduces the temperature of the heat-conducting component 320 and / or the heat sink, and consequently reduces the temperature at the heating element 200, thereby reducing high temperature alarms and safety risks and ensuring operational efficiency.

[0071] Please see Figure 3 and Figure 4 In one embodiment, the heating element 200 includes a main control board 210, a first heat sink 311 is disposed on the main control board 210, and a first heat conductor 321 is attached to the first heat sink 311. The end of the first heat conductor 321 away from the heat sink 310 is attached to the metal counterweight 400. The main control board 210 generates a lot of heat during use, especially for some main control boards 210s that integrate fast charging modules, which generate even more heat during fast charging. By providing the first heat sink 311 on the main control board 210, the heat at the main control board 210 can be effectively dissipated, reducing the temperature at the main control board 210. The heat from the first heat sink 311 is conducted to the metal counterweight 400 by the first heat conductor 321, avoiding heat accumulation at the main control board 210, reducing the safety risks of the main control board 210, and ensuring the stable operation of the main control board 210.

[0072] In one embodiment, there is a certain gap between the first heat sink 311 and the main control board 210 to avoid the first heat sink 311 affecting the electronic components on the main control board 210.

[0073] In one embodiment, the first heat-conducting element 321 is at least partially attached to the first heat sink 311 near the processor of the main control board 210. The processor generates a lot of heat during operation. The first heat-conducting element 321 can quickly conduct the heat to this location, which can slow down the temperature rise of the processor and ensure stable and efficient operation of the processor.

[0074] Please see Figure 4 In one embodiment, the main control board 210 is disposed at the metal counterweight 400, for example above the metal counterweight 400, which facilitates the structural layout of the cleaning device 1 and also facilitates the rapid transfer of heat from the main control board 210 to the metal counterweight 400.

[0075] Please see Figure 3 and Figure 4 In one embodiment, the heating element 200 includes a battery 220, and a second heat-conducting element 322 is provided on the battery 220. One end of the second heat-conducting element 322, away from the battery 220, is in contact with the metal counterweight 400. The battery 220 generates considerable heat during use and charging, especially for fast-charging batteries 220, which generate a large amount of heat during charging. By providing the second heat-conducting element 322 on the surface of the battery 220, the heat from the battery 220 surface can be transferred to the metal counterweight 400, effectively slowing down the temperature rise of the battery 220 surface, ensuring the continuous use of the cleaning device 1, and shortening the charging time of the battery 220. Controlling the temperature rise of the battery 220 within a reasonable range meets safety requirements and enhances the market competitiveness of the cleaning device 1.

[0076] Please see Figure 4 In one embodiment, a second heat sink 312 is attached to the battery 220, and the second heat sink 312 is attached to the second heat conductor 322. By attaching the second heat sink 312 to the surface of the battery 220, the heat on the surface of the battery 220 is transferred to the second heat sink 312 through thermal radiation and thermal conduction, and then transferred to the metal counterweight 400 through the second heat conductor 322, effectively slowing down the temperature rise of the surface of the battery 220, shortening the charging time, and ensuring the continuous use of the cleaning device 1. The second heat sink 312 can be disposed between the battery 220 and the second heat conductor 322, that is, the battery 220, the second heat sink 312, and the second heat conductor 322 are arranged in sequence; the second heat conductor 322 can also be disposed between the second heat sink 312 and the battery 220, that is, the second heat conductor 322 is attached to the surface of the battery 220, and the second heat sink 312 is partially attached to the second heat conductor 322 and partially attached to the surface of the battery 220.

[0077] Please see Figure 4In one embodiment, a third heat sink 313 is attached to the metal counterweight 400, and the third heat sink 313 is disposed between the heat-conducting component 320 and the metal counterweight 400. For example, the third heat sink 313 is attached to the surface of the metal counterweight 400, and the second heat-conducting component 322 is attached to the third heat sink 313; or, the third heat sink 313 is attached to the surface of the metal counterweight 400, and the second heat-conducting component 322 is attached to the third heat sink 313, etc. To reduce costs, the metal counterweight 400 is usually made of cast iron. The surface of cast iron is relatively rough, which affects the adhesion with the heat-conducting component 320. By attaching a third heat sink 313 to the metal counterweight 400, the third heat sink 313, which has a large area, increases the contact area with the metal counterweight 400, thereby improving the heat transfer efficiency from the heat conductor 320 to the metal counterweight 400. This effectively reduces heat accumulation at the heating element 200, slows down the temperature rise at the heating element 200, and keeps the temperature at the heating element 200 within a controllable range, meeting safety requirements and ensuring efficiency.

[0078] The number of the third heat sink 313 can be one or more, such as two, three, or four, depending on the heat dissipation requirements and cost considerations.

[0079] Please see Figure 4 In one embodiment, the metal counterweight 400 is disposed near the battery 220, and both the metal counterweight 400 and the battery 220 are disposed below the main control board 210, so that the heat generated by the main control board 210 and the battery 220 can be quickly transferred to the metal counterweight 400, thereby improving the heat dissipation efficiency of the main control board 210 and the battery 220.

[0080] To improve thermal conductivity, the second thermal conductive element 322 is attached to the metal counterweight 400 near the battery 220 or above the side near the battery 220 to shorten the thermal conduction path and improve thermal conductivity.

[0081] Please see Figure 2 and Figure 3In one embodiment, the cleaning device 1 includes a container 500 and a fluid conduit 600, the container 500 being connected to the cleaning element. The container 500 is used to hold fluid, such as at least one of water, detergent, and disinfectant. The liquid in the container 500 can be supplied to the cleaning element to wet it, thereby enabling the cleaning element to interfere with the surface to be cleaned for wet cleaning. The fluid conduit 600 is connected to the metal counterweight 400 and / or the heat dissipation element 300, and at least one end of the fluid conduit 600 is connected to the container 500. Container 500 is used to hold liquids. Since liquids such as water have a high specific heat capacity, they can absorb a large amount of heat. The liquid is connected to the metal counterweight 400 and / or the heat dissipation element 300 through the fluid pipe. The liquid flows through the metal counterweight 400 and / or the heat dissipation element 300, which can absorb the heat at the metal counterweight 400 and / or the heat dissipation element 300. By lowering the temperature of the counterweight, the temperature of the heat dissipation element 300 is lowered, thereby lowering the temperature at the heating element 200, and / or the temperature of the heat dissipation element 300 is directly lowered, thereby lowering the temperature at the heating element 200. This can effectively slow down the temperature rise of the heating element 200, so that the temperature at the heating element 200 is controlled within a controllable range, meeting safety requirements and improving the safety of the cleaning equipment 1.

[0082] The fluid conduit 600 can be connected to the metal counterweight 400, for example, by fitting a portion of the surface of the metal counterweight 400, or by extending a portion of the fluid conduit 600 into the interior of the metal counterweight 400, to improve heat dissipation efficiency. The fluid conduit 600 can be connected to the heat dissipation element 300, for example, by fitting a portion of the surface or interior of the heat sink 310, to quickly dissipate heat from the heat sink 310; or by fitting a portion of the surface or interior of the heat conductor 320, to quickly dissipate heat from the heat conductor 320.

[0083] Current cleaning devices 1, especially self-propelled cleaning devices 1, suffer from severely insufficient battery life, slow charging after cleaning, and long charging times, negatively impacting user experience. To improve user experience, cleaning devices 1 could incorporate fast charging technology, which would rapidly and safely replenish the battery 220 during the brief period of cleaning or rinsing the cleaning components. However, fast charging would cause a significant amount of heat to be generated in the heat-generating components 200, such as the battery 220 and the charging control circuit. If this heat accumulates, the high temperature would reduce charging efficiency and affect the replenishment effect.

[0084] In one embodiment, the heating element 200 includes a charging circuit for connecting to the circuit of the base station 2 and charging the battery of the cleaning device 1.

[0085] For example, the charging circuit is a fast charging circuit to improve the charging speed of the battery 220 of the cleaning device 1. The battery 220 can be charged and recharged in the short time of cleaning or rinsing the cleaning elements, thereby extending the battery life of the cleaning device 1 and improving the user experience.

[0086] Please see Figure 2 , Figure 3 and Figure 7 In one embodiment, the cleaning device 1 includes a water inlet 700 configured to connect to the water path of the base station 2 and inject liquid into the container 500. One end of the fluid pipeline 600 is connected to the water inlet 700, and the other end is connected to the container 500. While cleaning or tidying the cleaning elements, the cleaning device 1 can be charged simultaneously. During charging, water is injected into the container 500 through the water inlet 700 via the liquid pipeline. The liquid flows through the metal counterweight 400 and / or the heat dissipation element 300, directly and / or indirectly reducing the temperature of the heat dissipation element 300, slowing down the temperature rise at the heating element 200, and controlling the temperature at the heating element 200 within a controllable range, effectively ensuring charging efficiency. By utilizing the water replenishment pipeline of the container 500, minimal modifications are required to the existing cleaning device 1, facilitating upgrades; no additional components such as water pumps are needed, reducing costs and improving the competitiveness of the cleaning device 1.

[0087] In one embodiment, when the charging circuit is connected to the circuit of the base station 2 and charges the battery 220 of the cleaning device 1, the base station 2 continuously injects liquid into the container 500 through the water inlet and the fluid pipeline 600 to slow down the temperature rise of the charging circuit, control the temperature of the charging circuit, ensure charging efficiency, improve charging speed, and extend the battery life of the cleaning device 1.

[0088] Of course, as some optional methods, the time for water to be injected into the container 500 from the water inlet 700 can be varied. For example, water injection can be started when the heat generated during charging is high and the temperature of the heating element 200 exceeds a preset threshold to avoid overheating of the heating element 200; or, the time required for water injection into the container 500 and the time for charging or cleaning the element are calculated, and water injection into the container 500 is completed before the cleaning or charging ends, that is, the water injection ends no later than the cleaning or charging ends; or, water injection can be started when the temperature of the heating element 200 exceeds a preset high temperature threshold and stopped when it falls below a preset low temperature threshold, until charging or cleaning is completed, etc.

[0089] The flow of liquid through the metal counterweight 400 and / or the heat dissipation element 300 is controlled by the fluid conduit 600. For example, if the fluid conduit 600 is connected to the metal counterweight 400, the liquid flows through the metal counterweight 400; if the fluid conduit 600 is connected to the heat dissipation element 300, the liquid flows through the heat dissipation element 300; if the fluid conduit 600 is connected to both the metal counterweight 400 and the heat dissipation element 300, the liquid flows through both the metal counterweight 400 and the heat dissipation element 300.

[0090] Please see Figure 2 and Figure 3 In one embodiment, the container 500 includes an overflow pipe 800, one end of which is connected to the container 500, and the other end of which is connected to the drainage system of the base station 2 to drain excess liquid from the container 500. For example, when the liquid level in the container 500 reaches a preset threshold or when liquid needs to be drained, the excess liquid is drained from the cleaning device 1 through the overflow pipe 800. For example, during fast charging, the heating element 200 generates a lot of heat, requiring continuous cooling through the fluid pipe 600, which causes the container 500 to fill with liquid. The excess liquid overflows through the overflow pipe 800 to ensure liquid flow within the fluid pipe 600, thereby continuously dissipating heat and continuously controlling the temperature at the heating element 200.

[0091] In one embodiment, the metal counterweight 400 has an installation channel, and at least a portion of the fluid conduit 600 is accommodated within the installation channel. The fluid conduit 600 is in contact with the inner wall of at least a portion of the installation channel, which can improve the stability of the contact between the fluid conduit 600 and the metal counterweight 400, which is beneficial to increasing the contact area between the fluid conduit 600 and the metal counterweight 400, improving the heat dissipation efficiency of the metal counterweight 400, and thus effectively improving the heat dissipation efficiency at the heating element 200.

[0092] In one embodiment, the installation channel penetrates the metal counterweight 400; the metal counterweight 400 includes an even number of installation channels penetrating the metal counterweight 400. The installation channels penetrating the metal counterweight 400 facilitate the passage of the fluid pipeline 600, thus simplifying its installation. The water inlet 700 and container 500 of the cleaning device 1 are typically located on the same side of the cleaning device 1, and less frequently on opposite sides. The even number of installation channels allows the fluid pipeline 600 to bend, maximizing the utilization of the existing space on the cleaning device 1 for the fluid pipeline 600, facilitating spatial layout, and reducing costs.

[0093] In one embodiment, the two ends of the fluid pipeline 600 are connected to the container 500, and the fluid pipeline 600 and the container 500 form a circulation loop. The liquid in the fluid pipeline 600 and the container 500 circulates, thereby removing the heat from the metal counterweight 400 and / or the heat dissipation element 300, slowing down the temperature rise of the heating element 200, ensuring the efficiency of the heating element 200, and improving the safety of the cleaning equipment 1.

[0094] In one embodiment, the cleaning device 1 includes a water pump disposed on the fluid conduit 600. The water pump is configured to circulate the liquid within the fluid conduit 600 and the container 500. The water pump allows the fluid to circulate within the circulation path formed by the fluid conduit 600 and the container 500. As the fluid flows through the fluid conduit 600 in contact with the metal counterweight 400 and / or the heat dissipation element 300, heat exchange occurs, absorbing heat from the metal counterweight 400 and / or the heat dissipation element 300. In subsequent circulation, the fluid exchanges heat with the water in the container 500 that has not undergone heat exchange, thus lowering its temperature. This cycle achieves cooling and heat dissipation of the metal counterweight 400 and / or the heat dissipation element 300, effectively slowing down the temperature rise at the heating element 200 and keeping its temperature within a controllable range.

[0095] In one embodiment, the cleaning device 1 includes a container 500 and a fluid conduit 600. The container 500 is connected to the cleaning element; the fluid conduit 600 is connected to the heating element 200, and at least one end of the fluid conduit 600 is in communication with the container 500. The container 500 is used to hold liquid, and the fluid conduit 600, when connected to the heating element 200, can absorb the heat from the heating element 200 by flowing through the fluid conduit 600, thereby slowing down the temperature rise at the heating element 200 and controlling the temperature at the heating element 200 within a controllable range to meet safety requirements and improve the safety of using the cleaning device 1.

[0096] The connection between the fluid conduit 600 and the heating element 200 can be: the fluid conduit 600 is in contact with the surface of the heating element 200; or the fluid conduit 600 extends into the interior of the heating element 200 and is in contact with the interior of the heating element 200; or a portion of the fluid conduit 600 extends into the interior of the heating element 200 and a portion of the element is in contact with the surface of the heating element 200.

[0097] In one embodiment, the cleaning device 1 includes a water inlet 700 configured to inject liquid into the container 500. One end of a fluid conduit 600 is connected to the water inlet 700, and the other end is connected to the container 500. The fluid conduit 600 is also connected to the heating element 200. The cleaning device 1 injects water into the container 500 through the water inlet 700 and the liquid flows through the heating element 200, slowing down the temperature rise at the heating element 200 and keeping its temperature within a controllable range, effectively ensuring charging efficiency. By utilizing the water supply conduit of the container 500, minimal modifications are required to the existing cleaning device 1, facilitating upgrades. No additional components such as water pumps are needed, reducing costs and enhancing the competitiveness of the cleaning device 1. The fluid conduit 600, directly connected to the heating element 200, allows for faster heat dissipation from the heating element 200, effectively slowing down its temperature rise.

[0098] In one embodiment, the cleaning device 1 includes a water pump disposed on the fluid pipeline 600. Both ends of the fluid pipeline 600 are connected to the container 500, and the fluid pipeline 600 is connected to the heating element 200. The water pump is configured to circulate the liquid within the fluid pipeline 600 and the container 500. The water pump allows the fluid to circulate within the circulation path formed by the fluid pipeline 600 and the container 500. As the liquid flows through the fluid pipeline 600 in contact with the heating element 200, heat exchange occurs. In subsequent circulation, the liquid exchanges heat with the water in the container 500 that has not undergone heat exchange, thus lowering its temperature. This cycle achieves cooling and heat dissipation at the heating element 200, effectively slowing down the temperature rise at the heating element 200 and keeping its temperature within a controllable range.

[0099] The cleaning device 1 of this utility model, by setting a heat dissipation element 300 at the heating element 200, allows the heat generated by the heating element 200 to be transferred to the heat dissipation element 300 through one or more heat transfer methods such as thermal radiation, thermal conduction, and thermal convection. The heat dissipation plate 310 and the heat-conducting component 320 have a large heat dissipation area, thereby improving the heat dissipation efficiency of the heating element 200. The thermal conductivity coefficient of the heat-conducting component 320 is greater than that of the heat dissipation plate 310, allowing the heat-conducting component 320 to conduct heat from the heat dissipation plate 310 and / or the heating element 200 more quickly, preventing heat accumulation at the heating element 200, reducing the temperature at the heating element 200, reducing high temperature alarms and safety risks, ensuring the efficiency of the cleaning device 1, and improving the safety of the cleaning device 1; by attaching the heat-conducting component 320 and / or the heat dissipation plate 310 to the metal counterweight 400, the heat from the heat-conducting component 320 and / or the heat dissipation component can be quickly conducted and transferred through the surface of the metal counterweight 400 via thermal radiation and thermal convection, effectively improving the heat dissipation capacity. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0100] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
