[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Please refer to Figures 1 to 10 This utility model provides a cleaning device, which includes: a housing 1, a cleaning component, a heating element 2, a heat-conducting component 3, and a driving component 4. The housing 1 has an air duct 10 for air circulation. The cleaning component is installed on the housing 1 and is used to clean external objects. The heating element 2 is a functional component installed on the housing 1 and generates heat when it is working. The heat-conducting component 3 is in contact with the heating element 2, and at least a portion of the inner wall surface of the air duct 10 is the surface of the heat-conducting component 3. The driving component 4 drives the air to flow within the air duct 10.

[0035] The cleaning device with this structural design incorporates a heat-conducting element 3 that contacts the heating element 2. At least a portion of the surface of the heat-conducting element 3 serves as the inner wall of the air duct 10 for direct heat dissipation. The heat generated by the heating element 2 during operation is conducted to the heat-conducting element 3. The airflow within the air duct 10 is driven by the driving component 4. As the air flows along the surface of the heat-conducting element 3, it efficiently removes heat from the element. By designing the air duct 10, heat-conducting element 3, and driving component 4 as described above, heat dissipation of the heating element 2 is effectively enhanced, preventing malfunctions caused by excessively high heating element temperatures during operation. This significantly improves the reliability of the cleaning device, making it particularly suitable for use in high-temperature environments and long-term continuous operation. It also solves the technical problem of poor performance of internal heating elements in related cleaning equipment.

[0036] The purpose of the heat-conducting component 3 contacting the heating element 2 is to achieve heat conduction. In actual implementation, the two can be in direct contact, or the gap between them can be filled by the heat-conducting material in the middle, so that the two can be indirect contact to achieve heat conduction. The "contact" in the context can be understood as this kind of cooperation relationship.

[0037] As described above, the heating element 2 is a functional component (a component that performs a corresponding function during operation, such as a battery, motor, etc.) disposed in the housing 1, which generates heat during operation. Specifically, it can be a component that performs various functions, as long as it generates a lot of heat during operation and has a heat dissipation requirement. For example, in an optional embodiment, the heating element 2 is a battery, which is used to power the cleaning device. In related technologies, the battery generates a lot of heat during use, causing the battery temperature to become too high, or even triggering temperature protection, causing the cleaning device to shut down or fail to start. However, the cleaning device of this utility model embodiment, due to the design of the air duct 10, heat-conducting component 3, drive component 4, and other structures, can enhance the heat dissipation of the battery, ensure the reliability of the battery during use, and thus ensure the normal operation of the cleaning device. Actual verification has shown that in related technologies without the above-mentioned structure design of the air duct 10, heat-conducting component 3, drive component 4, etc., the battery temperature can reach an average of 59°C to 60°C when used in high ambient temperatures or for a long time. When the above-mentioned air duct 10, heat conduction component 3, drive component 4 and other structural designs are adopted, the heat dissipation of the battery can be significantly improved, the battery temperature can be reduced by about 10°C, and the average temperature when used in high ambient temperature or for a long time can be controlled at about 49°C, which can effectively improve the reliability and life of the battery.

[0038] In practical implementation, cleaning components can take many different forms depending on the cleaning function. For example, they can be used for sweeping, scrubbing, vacuuming, etc. Correspondingly, the specific structure of the cleaning components can be a roller brush, mop, vacuuming structure, etc. The specific structural form can be selected according to the specific cleaning needs, and is not limited here.

[0039] As its name suggests, the heat-conducting component 3 conducts heat. Through contact with the heating element 2, heat from the heating element 2 is transferred to the heat-conducting component 3, and then carried away by the air in the air duct 10, thereby enhancing the heat dissipation of the heating element 2. The material and shape of the heat-conducting component 3 are not limited here; it can be any structure that enhances heat dissipation of the heating element 2 through thermal conduction. For example, the heat-conducting component 3 can be made of metal to ensure good thermal conductivity. In a specific embodiment, the heat-conducting component 3 is made of aluminum.

[0040] As mentioned above, the function of the driving component 4 is to drive the air flow within the air duct 10. In specific implementations, there are various structures to choose from, as long as they can drive the air flow. For example, it can be an axial flow fan, a centrifugal fan, a cross flow fan, etc.

[0041] In a preferred embodiment, the cleaning device includes a dust suction structure, which includes a fan, and the driving component 4 is the fan.

[0042] The suction structure is used to suck up external dust, hair, and other debris. It includes a fan that provides negative pressure to the suction structure. In this embodiment, by using the fan as the driving component 4 to drive the airflow within the air duct 10, the existing structure is utilized more effectively. No additional fan or other structures are needed to drive the air within the air duct 10, simplifying the structure of the cleaning device, reducing manufacturing costs, and improving operational stability.

[0043] Specifically, the housing 1 is provided with an air guide channel 101. One end of the air guide channel 101 is connected to the fan outlet 102 of the fan, and the other end of the air guide channel 101 is connected to the air inlet 103 of the air duct 10, so as to guide part of the air blown by the fan to the air duct 10 through the air guide channel 101. Figure 6 As shown, Figure 6 The green arrows indicate the direction of airflow into the air duct 10, and the red arrows indicate the direction of airflow out of the air duct 10. After the air flows out of the fan outlet 102 of the drive component 4 (fan), it flows into the air duct 10 through the air guide channel 101 and the air inlet 103. After exchanging heat with the heat-conducting component 3, the hot air flows out through the air outlet 104, thereby achieving heat dissipation for the heat-conducting component 3.

[0044] In this embodiment, by designing an air guide channel 101 on the housing 1, part of the air outlet 102 of the fan is guided to the air duct 10, thereby driving the airflow within the air duct 10. As an optional embodiment, the cleaning device includes a valve structure installed in the air duct 10 or the air guide channel 101. The valve structure controls the airflow within the air duct 10, allowing more air to enter the air guide channel 101 when the cooling demand of the heating element 2 is high, thus improving the heat dissipation effect of the heating element 2. In another optional embodiment, a spray device or water spray device is provided inside the air duct 10 or at its inlet. By spraying water / mist into the air duct 10, more heat can be carried away through water evaporation, further enhancing the heat dissipation effect on the heating element 2.

[0045] In an optional embodiment, the housing 1 is provided with a cleaning component mounting slot 11, and the cleaning component is mounted in the cleaning component mounting slot 11, wherein the air outlet 104 of the air duct 10 extends to the cleaning component mounting slot 11.

[0046] The cleaning component mounting slot 11 is the location for installing the cleaning component. In this embodiment, by designing the air outlet 104 of the air duct 10 at the cleaning component mounting slot 11, it is possible to prevent the air outlet of the air duct 10 from blowing up surrounding dust, hair, and other debris, reducing dust and ensuring a clean operating environment for the cleaning device. Furthermore, guiding the air outlet of the air duct 10 to the vicinity of the cleaning component also helps reduce noise in the cleaning device. Specifically, by setting the air outlet of the air duct 10 at the cleaning component mounting slot 11, it is beneficial to reduce the diffusion of air outlet noise to the outside; moreover, this arrangement makes the noise generation location more concentrated, avoiding the situation where noise sources are dispersed and thus cause external noise to accumulate and increase. In addition, in some embodiments, the cleaning device includes a dust suction structure, with the air inlet and / or outlet of the dust suction structure located at the cleaning component mounting slot 11. By guiding the air outlet of the air duct 10 to the cleaning component mounting slot 11, the airflow of the dust suction structure and the airflow of the air duct 10 collide, which helps to reduce the wind speed at the cleaning component mounting slot 11, thereby making the cleaning device operate more quietly.

[0047] In a preferred embodiment, the air outlet 104 of the air duct 10 is located near and adjacent to the cleaning component mounting slot 11, and the air outlet 104 faces outwards from the body of the cleaning device. The air outlet 104 of the air duct 10 is not located within the cleaning component mounting slot 11, which avoids the generation of circulating hot air in the air duct 10, thus preventing it from affecting the heat dissipation effect on the heat-generating element 2.

[0048] In this embodiment, the heat-conducting component 3 is a plate-shaped structure. The plate-shaped structure separates the air duct 10 from the heating element mounting chamber. The heating element 2 is installed in the heating element mounting chamber. The first plate surface of the plate-shaped structure is in contact with the heating element 2. The second plate surface of the plate-shaped structure serves as part of the inner wall surface of the air duct 10. The second plate surface is in contact with the air in the air duct 10. The first plate surface and the second plate surface are two opposite plate surfaces of the plate-shaped structure.

[0049] By designing the heat-conducting component 3 as a plate-like structure, it separates the air duct 10 from the heating element mounting chamber. The heating element 2 is mounted on one side of the heat-conducting component 3, and the air duct is on the other side. The heat from the heating element 2 can be directly conducted to the heat-conducting component 3. The other side of the heat-conducting component 3 comes into contact with the airflow within the air duct 10, thereby dissipating the heat. This structural design not only makes the heat dissipation-related structures compact but also makes full use of the two large surfaces of the plate-like structure, which is beneficial for ensuring the heat dissipation effect on the heating element 2. The first and second surfaces are the two largest surfaces of the plate-like structure.

[0050] In one optional embodiment, the second plate of the plate-like structure is provided with multiple fins, thereby increasing the surface area of ​​the heat-conducting element 3 and improving the heat exchange efficiency between the heat-conducting element 3 and the air. Preferably, the multiple fins extend along the length of the air duct 10, thereby reducing their obstruction to airflow.

[0051] Specifically, the air duct 10 has a flat structure, and the width of the flow section of the air duct 10 is greater than the height of the flow section of the air duct 10. The flow section is a section perpendicular to the air flow direction in the air duct 10, the height is in the direction of the thickness of the plate-like structure, and the width is perpendicular to the height.

[0052] By designing the air duct 10 as a flat structure, the air flowing within the air duct 10 can be brought closer to the heat-conducting component 3, thereby exchanging heat more fully with the heat-conducting component 3 and improving the heat dissipation effect on the heat-generating element 2. It should be noted that the width and height mentioned above do not refer to orientation, but only to the dimensions of the air duct's cross-section in different directions. The height does not specifically refer to the vertical direction, but rather to the direction perpendicular to the width direction, and is unrelated to the placement posture of the cleaning device.

[0053] In an optional embodiment, a guide surface is provided at the corner of the inner wall of the air duct 10, and at least a portion of the guide surface is an arc-shaped surface.

[0054] In this embodiment, by designing a guide surface including an arc-shaped surface at the inner corner of the air duct 10, the air resistance in the air duct 10 can be reduced, making the airflow in the air duct 10 flow more smoothly, thereby improving the heat exchange efficiency between the air and the heat-conducting component 3, and thus improving the heat dissipation effect on the heat-generating element 2.

[0055] In this embodiment, a cover plate 12 is provided on the housing 1 at a position corresponding to the air duct 10. The cover plate 12 is detachably installed on the main body of the housing 1 and separates the air duct 10 from the external space of the housing 1.

[0056] By designing a removable cover plate 12 at the air duct 10, it is convenient to observe and maintain the air duct 10. For example, when the heat dissipation effect on the heat-generating element 2 deteriorates, the cover plate 12 can be removed to observe whether the air duct 10 is blocked, and the air duct 10 can be cleaned when it is blocked.

[0057] Preferably, a recessed structure is provided on the main body of the housing 1 at a position corresponding to the cover plate 12, and the cover plate 12 is placed on the recessed structure to form an air duct 10, wherein the cover plate 12 and the recessed structure are both extended along the length direction of the air duct 10.

[0058] By designing a recessed structure on the main body of the housing 1, the aforementioned air duct 10 is formed when the cover plate 12 is placed on the recessed structure. This design reduces the processing difficulty of the air duct 10, makes it easy to manufacture the air duct 10 on the housing 1, and facilitates the observation and maintenance of the interior of the air duct 10, thus having a good practical application effect.

[0059] As mentioned above, the heating element 2 can be a component that performs various functions, as long as it generates a lot of heat during operation and has a heat dissipation requirement. For example, the heating element 2 can be a battery, circuit board, chip, etc.

[0060] In the first optional embodiment, such as Figures 1 to 9 As shown, the heating element 2 is a battery, which is connected to the cleaning components or other structures of the cleaning device to provide power. In related technologies, when cleaning devices are used for extended periods or in high-temperature environments, the battery heat cannot be dissipated to the surrounding environment in a timely manner, leading to a rise in battery temperature, affecting battery life, and even triggering battery protection, causing the cleaning device to shut down or fail to start. In this embodiment, by designing a heat-conducting component 3 in contact with the battery, the heat generated by the battery can be conducted to the heat-conducting component 3. The airflow within the air duct 10, driven by the driving component 4, can carry away the heat on the heat-conducting component 3, thereby achieving efficient heat dissipation of the battery and keeping the battery temperature within a reasonable range, thus ensuring the normal operation of the cleaning device. Specifically, the housing 1 has a battery mounting slot, in which the battery is installed. The heat-conducting component 3 is located at the opening of the battery mounting slot and in contact with the battery, thus confining the battery within the battery mounting slot. The side of the heat-conducting component 3 away from the battery forms an air duct 10 between itself and the housing 1. In this way, during installation, simply place the battery in the battery mounting slot and then install the heat-conducting component 3 to fix and limit the battery, and also to dissipate heat from the battery. While ensuring the installation and fixation effect of the battery and the heat dissipation effect, the installation structure and installation operation are effectively simplified.

[0061] In the second optional embodiment, the heating element 2 is a circuit board. During the use of the cleaning device, there may be several heating elements on the circuit board, leading to excessively high overall temperature. This could affect the normal operation of the components on it, or even cause damage. In this embodiment, by using a heat-conducting component 3 in contact with the circuit board, the heat from the circuit board can be efficiently conducted to the heat-conducting component 3. Combined with the airflow driven by the driving component 4 within the air duct 10, the heat on the heat-conducting component 3 can be carried away, achieving efficient heat dissipation for the entire circuit board and ensuring the normal operation of the circuit board and its components.

[0062] In a third alternative embodiment, such as Figure 10 As shown, the heating element 2 is a chip. A chip can refer to a chip that requires extensive calculations on large amounts of data, such as a CPU, but is not limited to these. This chip is mounted on a circuit board. In actual use, the chip easily generates a lot of heat due to performing numerous calculations. If this heat is concentrated for a long time and cannot dissipate, it may cause the chip and its surrounding environment to become too hot, affecting its performance and lifespan, or leading to faults such as poor soldering. In this embodiment, the heat from the chip is conducted away using a heat-conducting component 3. Then, the airflow within the air duct 10 is driven by a driving component 4, thereby carrying away the heat from the heat-conducting component 3. This allows the heat at the chip to be efficiently dissipated to the surrounding environment, preventing heat accumulation at the chip and ensuring the chip operates at a lower temperature, thus guaranteeing its operational reliability. Specifically, the heating element 2 is a chip, and the heat-conducting component 3 includes: a first part 31, which is thermally connected to the chip (any connection method that enables heat conduction is acceptable); and a second part 32, which is connected to the first part 31. At least a portion of the inner wall surface of the air duct 10 is the surface of the second part 32. By designing a system that interconnects the first part 31 and the second part 32, heat from the first part 31 can be transferred to the second part 32 through thermal conduction. Then, the heat from the second part 32 is carried away by the air flowing along the surface of the second part 32 within the air duct 10. This structural design can adapt well to the chip installation environment and ensure efficient heat dissipation of the chip without interfering with the chip installation.

[0063] In this design, when the first part 31 is in thermally conductive contact with the chip, the second part 32 is located on the side of the chip. The thermally conductive component 3 also includes a heat sink 33, which is disposed on the side of the first part 31 away from the chip. By placing the second part 32 on the side of the chip, sufficient space is provided on the side of the first part 31 away from the chip, allowing the heat sink 33 to be designed on that side. In this way, the heat generated by the chip can be dissipated through both the second part 32 and the heat sink 33, thereby further improving the chip's heat dissipation effect.

[0064] In this embodiment, the chip is mounted on the circuit board 20. A groove is provided on the side of the first part 31 facing the chip, and the groove is secured to the circuit board 20. The chip is located within the groove, thus protecting the chip. The gap between the chip and the first part 31 is filled with a thermally conductive material 30, thereby enhancing the heat conduction between the first part 31 and the chip and improving the heat dissipation effect on the chip. The thermally conductive material 30 can be any material that can improve the heat conduction between the chip and the first part 31, such as thermal grease. In a preferred embodiment, a bend 34 is provided at the connection between the first part 31 and the second part 32, meaning the first part 31 and the second part 32 are connected by the bend 34, creating a height difference between them. This better adapts to the chip's mounting environment and ensures effective heat transfer.

[0065] In addition, an embodiment of this utility model also provides a sweeping machine, which includes a cleaning device, wherein the cleaning device is the cleaning device described above.

[0066] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0067] The cleaning device of this utility model embodiment includes: a housing 1, a cleaning component, a heating element 2, a heat-conducting element 3, and a driving component 4. The housing 1 has an air duct 10 for air circulation. The cleaning component is installed on the housing 1 and is used to clean external objects. The heating element 2 is a functional component installed on the housing 1, and generates heat when it operates. The heat-conducting element 3 is in contact with the heating element 2, and at least a portion of the inner wall surface of the air duct 10 serves as the surface of the heat-conducting element 3. The driving component 4 drives the airflow within the air duct 10. This cleaning device, with its structural design, incorporates a heat-conducting element 3 in contact with the heating element 2, and at least a portion of the surface of the heat-conducting element 3 directly dissipates heat as the inner wall surface of the air duct 10. The heat generated by the heating element 2 during use is conducted to the heat-conducting element 3. The driving component 4 drives the airflow within the air duct 10, and as the air flows along the surface of the heat-conducting element 3, the heat on the heat-conducting element 3 can be carried away more efficiently. By designing the air duct 10, heat-conducting component 3, and driving component 4 of the above structure, the heat dissipation of the heating element 2 is effectively enhanced, avoiding the occurrence of malfunctions caused by excessively high temperature of the heating element during the use of the cleaning device. This effectively improves the reliability of the cleaning device, making it particularly suitable for use in high-temperature environments and long-term continuous operation. It also solves the technical problem of poor working effect of the internal heating element of the cleaning equipment in related technologies.

[0068] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below."
