[0033] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0034] Please refer to Figures 1 to 10 , an embodiment of the present invention provides a cleaning device, which includes: a housing 1, a cleaning component, a heating element 2, a heat-conducting member 3, and a driving component 4. Among them, the housing 1 has an air duct 10 for air circulation; the cleaning component is installed on the housing 1 and is used for cleaning an external object; the heating element 2 is a functional component installed on the housing 1, and the heating element 2 generates heat when working; the heat-conducting member 3 is in contact with the heating element 2, and at least a part of the inner wall surface of the air duct 10 is the surface of the heat-conducting member 3; the driving component 4 drives the air flow in the air duct 10.
[0035] For the cleaning device adopting this structural design, a heat conducting member 3 in contact with the heating element 2 is designed, and at least part of the surface of the heat conducting member 3 is used as the inner wall surface of the air duct 10 for direct heat dissipation. When the heating element 2 is in use, the generated heat is conducted to the heat conducting member 3. By driving the air flow in the air duct 10 through the driving member 4, when the air flows along the surface of the heat conducting member 3, the heat on the heat conducting member 3 can be taken away more efficiently. By designing the air duct 10, the heat conducting member 3 and the driving member 4 with the above structures, the heat dissipation of the heating element 2 is effectively strengthened, the situation that the cleaning device fails due to the overhigh temperature of the heating element during use is avoided, and the reliability of the cleaning device during use is effectively improved. It is especially suitable for use in high-temperature environments, long-term continuous operation, etc., and solves the technical problem of the poor working effect of the heating element inside the cleaning device in the related art.
[0036] The purpose of the heat conducting member 3 being in contact with the heating element 2 is to achieve heat conduction. In actual implementation, the two can be in direct contact, or the gap between the two can be filled with an intermediate heat conducting material to make the two indirectly in 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 arranged in the housing 1 (a component that realizes corresponding functions during operation, such as a battery, a motor, etc.), and it will generate heat during operation. Specifically, it can be a component that realizes various functions, as long as it generates more heat and has a heat dissipation requirement during operation. For example, in an optional embodiment, the heating element 2 is a battery, and the battery is used to supply power to the cleaning device. In the related art, when the cleaning device is in use, the battery will generate more heat, resulting in an overhigh battery temperature, and even triggering temperature protection, causing the cleaning device to stop or fail to start. However, for the cleaning device of the embodiment of the present invention, due to the design of structures such as the air duct 10, the heat conducting member 3, and the driving member 4, the heat dissipation of the battery can be strengthened, the reliability of the battery during use can be guaranteed, and thus the normal operation of the cleaning device can be ensured. It is actually verified that when the structures such as the air duct 10, the heat conducting member 3, and the driving member 4 with the above structural design are not adopted in the related art, the temperature of the battery can reach an average of 59°C to 60°C when used in a higher ambient temperature or for a long time. However, when the above structural design of the air duct 10, the heat conducting member 3, and the driving member 4 is adopted, the heat dissipation situation of the battery can be significantly improved, the battery temperature can be reduced by about 10°C, and its average temperature when used in a higher ambient temperature or for a long time can be controlled at about 49°C, which can effectively improve the reliability and service life of the battery operation.
[0038] In actual implementation, according to different cleaning functions, the cleaning component can have various different forms of selection. For example, it can be cleaning methods such as sweeping, scrubbing, vacuuming, etc. Correspondingly, the specific structure of the cleaning component can be a rotary brush, a mop, a vacuuming structure, etc. Its specific structural form can be selected according to specific cleaning requirements and is not limited here.
[0039] For the heat conducting member 3, as the name implies, its function is to conduct heat. By contacting the heating element 2, the heat on the heating element 2 is conducted to the heat conducting member 3, and then the heat on the heat conducting member 3 is taken away by the air in the air duct 10, thereby strengthening the heat dissipation effect on the heating element 2. The material and shape of the heat conducting member 3 are not limited here, and it can be any structure that can enhance the heat dissipation of the heating element 2 through heat conduction. For example, the heat conducting member 3 can be made of a metal material to ensure its good heat conduction effect. In a specific embodiment, the heat conducting member 3 is made of aluminum.
[0040] As described above, the function of the driving component 4 is to drive the air flow in the air duct 10. In actual implementation, there are also various structures to choose from, as long as it can play the role of driving 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 vacuuming structure, the vacuuming structure includes a fan, and the driving component 4 is a fan.
[0042] The vacuuming structure is a structure used to suck up external dust, hair and other sundries, and it includes a fan. The fan is used to provide negative pressure for the vacuuming structure. In this embodiment, by using this fan as the driving component 4 to drive the air flow in the air duct 10, the utilization of the existing structure is more effectively realized, and there is no need to set up additional structures such as a fan to drive the air in the air duct 10, which simplifies the structure of the cleaning device, is beneficial to reducing the manufacturing cost of the cleaning device, and improves the operation stability of the cleaning device.
[0043] Specifically, a wind guiding channel 101 is provided on the housing 1. One end of the wind guiding channel 101 is communicated with the fan outlet 102 of the fan, and the other end of the wind guiding channel 101 is communicated with the air inlet 103 of the air duct 10 to guide a part of the air blown out by the fan to the air duct 10 through the wind guiding channel 101. As Figure 6 shown, Figure 6 the green arrow in is the air flow direction entering the air duct 10, and the red arrow is the air flow direction flowing out of the air duct 10. After the air flows out from the fan outlet 102 of the driving component 4 (fan), it flows into the air duct 10 through the wind guiding channel 101 and the air inlet 103. After exchanging heat with the heat conducting member 3, the hot air flows out through the air outlet 104, thereby realizing the heat dissipation of the heat conducting member 3.
[0044] In this embodiment, by designing an air guiding channel 101 on the housing 1, a part of the air discharged from the blower outlet 102 is guided to the air duct 10, so as to drive the air flow in the air duct 10. As an alternative embodiment, the cleaning device includes a valve structure, and the valve structure is installed in the air duct 10 or the air guiding channel 101 to control the air flow in the air duct 10. Thus, when the cooling requirement of the heating element 2 is high, more air can be controlled to enter the air guiding channel 101 through the valve structure, improving the heat dissipation effect of the heating element 2. In another alternative embodiment, a spraying device or a water spraying device is provided in the air duct 10 or at the inlet of the air duct 10. By spraying water / spray into the air duct 10 through the spraying device or the water spraying device, more heat can be taken away by the evaporation of water, further strengthening the heat dissipation effect on the heating element 2.
[0045] In an alternative embodiment, a cleaning component mounting groove 11 is provided on the housing 1, and the cleaning component is mounted in the cleaning component mounting groove 11. Wherein, the air outlet 104 of the air duct 10 extends to the cleaning component mounting groove 11.
[0046] The cleaning component mounting groove 11 is a position for mounting the cleaning component. In this embodiment, by designing the air outlet 104 of the air duct 10 at the cleaning component mounting groove 11, it is possible to prevent the air blown out from the air duct 10 from blowing up dust, hair and other sundries around, reducing the dust generation and being beneficial to ensuring the cleanliness of the use environment of the cleaning device. Moreover, guiding the air outlet of the air duct 10 to the vicinity of the cleaning component is also beneficial to realizing the noise reduction of the cleaning device. Specifically, by arranging the air outlet of the air duct 10 at the cleaning component mounting groove 11, it is beneficial to reduce the diffusion of the air outlet noise of the air duct to the outside; and adopting this setting method can make the noise generation position more concentrated, avoiding the situation where the noise sources are scattered, resulting in the superposition of external noises and making the noise larger. In addition, in some embodiments, the cleaning device includes a dust suction structure, and the air inlet position and / or the air outlet position of the dust suction structure is set at the cleaning component mounting groove 11. By guiding the air outlet of the air duct 10 to the cleaning component mounting groove 11, the air flow of the dust suction structure is in counterflow with the air outlet flow of the air duct 10, which is beneficial to reducing the air velocity at the cleaning component mounting groove 11, and further making the cleaning device operate more quietly.
[0047] As a preferred embodiment, the air outlet 104 of the air duct 10 is arranged near the cleaning component mounting groove 11, adjacent to the cleaning component mounting groove 11, and the air outlet 104 faces the outside of the body of the cleaning device. The air outlet 104 of the air duct 10 is not arranged in the cleaning component mounting groove 11, which can avoid generating circulating hot air in the air duct 10 and thus affecting the heat dissipation effect on the heating element 2.
[0048] In this embodiment, the heat conducting member 3 has a plate-like structure. The plate-like structure separates the air duct 10 from the heat generating element installation chamber. The heat generating element 2 is installed in the heat generating element installation chamber. The first plate surface of the plate-like structure contacts the heat generating element 2, and the second plate surface of the plate-like structure serves as a part of the inner wall surface of the air duct 10 and contacts the air in the air duct 10. The first plate surface and the second plate surface are two opposite plate surfaces of the plate-like structure.
[0049] By designing the heat conducting member 3 as a plate-like structure, it separates the air duct 10 from the heat generating element installation chamber. The heat generating element 2 is installed on one side of the heat conducting member 3, and the other side is the air duct. The heat of the heat generating element 2 can be directly conducted to the heat conducting member 3, and the other side of the heat conducting member 3 contacts the air flow in the air duct 10, thereby dissipating the heat. Adopting this structural design not only makes the heat dissipation-related structures arranged compactly, but also can make full use of the two large plate surfaces of the plate-like structure, which is beneficial to ensuring the heat dissipation effect on the heat generating element 2. Among them, the first plate surface and the second plate surface are the two largest surfaces of the plate-like structure.
[0050] In an alternative embodiment, a plurality of fins are provided on the second plate surface of the plate-like structure, thereby increasing the surface area of the heat conducting member 3 through the plurality of fins and improving the heat exchange efficiency between the heat conducting member 3 and the air. Preferably, the plurality of fins are all arranged to extend along the length direction of the air duct 10, thereby reducing the obstruction to the air flow.
[0051] Specifically, the air duct 10 has a flat structure. The width of the flow cross-section of the air duct 10 is greater than the height of the flow cross-section of the air duct 10. Among them, the flow cross-section is a cross-section perpendicular to the air flow direction in the air duct 10. The direction where the height is located is the thickness direction of the plate-like structure, and the direction where the width is located is perpendicular to the direction where the height is located.
[0052] By designing the air duct 10 as a flat structure, the air flowing in the air duct 10 can be closer to the heat conducting member 3, and thus can exchange heat with the heat conducting member 3 more fully, improving the heat dissipation effect on the heat generating element 2. It should be noted that the above-mentioned width and height do not refer to directions, but only represent the dimensions of the flow cross-section of the air duct in different directions. The height among them is not specifically the up and down direction, but the direction perpendicular to the width direction, which has nothing to do with the placement posture of the cleaning device.
[0053] In an alternative embodiment, a flow guiding surface is provided at the inner wall corner of the air duct 10, and at least part of the flow guiding surface is an arc surface.
[0054] In this embodiment, by designing a flow guiding surface including an arc surface at the inner wall corner of the air duct 10, the wind resistance in the air duct 10 can be reduced, making the air flow more smooth in the air duct 10, thereby improving the heat exchange efficiency between the air and the heat conducting member 3, and further improving the heat dissipation effect on the heat generating element 2.
[0055] In this embodiment, a cover plate 12 is provided at a position on the housing 1 corresponding to the air duct 10. The cover plate 12 is detachably mounted on the main body portion of the housing 1, and the cover plate 12 separates the air duct 10 from the external space of the housing 1.
[0056] By designing a detachable cover plate 12 at the air duct 10, it is convenient to observe and maintain the inside of the air duct 10. For example, when the heat dissipation effect of the heating element 2 becomes poor, the cover plate 12 can be removed to observe whether the air duct 10 is blocked and cleaned when the air duct 10 is blocked.
[0057] Preferably, a recessed structure is provided at a position on the main body portion of the housing 1 corresponding to the cover plate 12. The cover plate 12 covers the recessed structure to enclose the air duct 10. Among them, both the cover plate 12 and the recessed structure extend along the length direction of the air duct 10.
[0058] By designing a recessed structure on the main body portion of the housing 1, when the cover plate 12 covers the recessed structure, the above-mentioned air duct 10 is formed. By adopting this design method, the processing difficulty of the air duct 10 is reduced, the air duct 10 can be conveniently made on the housing 1, and it is convenient to observe and maintain the inside of the air duct 10, having a good practical application effect.
[0059] As described above, the heating element 2 can be a component that realizes various functions, as long as it generates more heat during operation and has a heat dissipation requirement. For example: the heating element 2 can be a battery, a circuit board, a chip, etc.
[0060] In the first alternative embodiment, as Figures 1 to 9 shown, the heating element 2 is a battery. The battery is connected to the cleaning component or other structures of the cleaning device to supply power to it. In the related art, when the cleaning device is used for a long time or in a high-temperature environment, the heat of the battery cannot be dissipated to the surrounding environment in time, resulting in an increase in the battery temperature, affecting the battery life and even triggering battery protection, resulting in power-off shutdown or inability to start of the cleaning device. In this embodiment, by designing a heat conducting member 3 to be in contact with the battery, the heat generated by the battery can be conducted to the heat conducting member 3. By driving the air flow in the air duct 10 by the driving member 4, the heat on the heat conducting member 3 can be taken away, thereby realizing efficient heat dissipation of the battery and keeping the battery temperature within a reasonable range, so as to ensure the normal operation of the cleaning device. Specifically, a battery installation groove is provided on the housing 1, the battery is installed in the battery installation groove, and the heat conducting member 3 is arranged at the notch of the battery installation groove and is in contact with the battery to limit the battery in the battery installation groove through the heat conducting member 3; a space between one side of the heat conducting member 3 away from the battery and the housing 1 forms the air duct 10. In this way, during installation, only the battery needs to be placed in the battery installation groove and then the heat conducting member 3 is installed, so that the battery can be fixed and limited, and the heat dissipation of the battery can also be realized. On the basis of ensuring the installation and fixing effect and heat dissipation effect of the battery, the installation structure and installation operation are effectively simplified.
[0061] In a second alternative embodiment, the heating element 2 is a circuit board. When the cleaning device is in use, there may be several heating elements on the circuit board, which may cause the overall temperature of the circuit board to be too high, which may affect the normal operation of the components thereon and even cause damage to the components. In this embodiment, by using the heat conducting member 3 in contact with the circuit board, the heat of the circuit board can be efficiently conducted to the heat conducting member 3, and then in cooperation with the driving member 4 to drive the air flow in the air duct 10, the heat on the heat conducting member 3 can be taken away, realizing efficient heat dissipation of the whole circuit board and ensuring the normal operation of the circuit board and the components thereon.
[0062] In a third alternative embodiment, as Figure 10 shown, the heating element 2 is a chip, which may refer to a chip that needs to perform a large amount of calculations on a large amount of data, a CPU, etc., but is not limited thereto. The chip is disposed on the circuit board. In actual use, the chip is likely to generate more heat due to performing a large number of operations. If this part of the heat is concentrated for a long time and cannot be dissipated, it may cause the temperature of the chip and its surroundings to be too high, affecting its performance and lifespan, or causing faults such as solder joint voids. In this embodiment, by using the heat conducting member 3 to conduct the heat of the chip out, and then driving the air flow in the air duct 10 through the driving member 4, the heat on the heat conducting member 3 can be taken away, enabling the heat at the chip to be efficiently dissipated to the surrounding environment, avoiding heat accumulation at the chip, and enabling the chip to work at a lower temperature, thereby ensuring the reliability of its operation. Specifically, the heating element 2 is a chip, and the heat conducting member 3 includes: a first part 31, the first part 31 is in heat conduction cooperation with the chip (any cooperation method that can achieve heat conduction is acceptable); a second part 32, the second part 32 is connected to the first part 31, and at least part of the inner wall surface of the air duct 10 is the surface of the second part 32. By designing the connection between the first part 31 and the second part 32, the heat of the first part 31 can be transferred to the second part 32 by heat conduction, and then the heat of the second part 32 can be taken away by the air flowing along the surface of the second part 32 in the air duct 10. Adopting this structural design can well adapt to the installation environment of the chip and ensure efficient heat dissipation of the chip without disturbing the installation of the chip.
[0063] Wherein, when the first part 31 is in heat conduction cooperation with the chip, the second part 32 is located on the side of the chip; the heat conducting member 3 further includes: heat dissipation fins 33, and the heat dissipation fins 33 are disposed on the side of the first part 31 away from the chip. By disposing the second part 32 on the side of the chip, sufficient space can be provided on the side of the first part 31 away from the chip, so that heat dissipation fins 33 can be designed on the side of the first part 31 away from the chip. In this way, the heat generated by the chip can be dissipated through two heat dissipation paths of the second part 32 and the heat dissipation fins 33, thereby further improving the chip heat dissipation effect.
[0064] In this embodiment, the chip is mounted on the circuit board 20. A groove is provided on one side of the first part 31 facing the chip. The groove is buckled on the circuit board 20, and the chip is located in the groove, thereby protecting the chip. The gap between the chip and the first part 31 is filled with a heat-conducting material 30, thereby strengthening the heat conduction between the first part 31 and the chip and improving the heat dissipation effect of the chip. Among them, the heat-conducting material 30 can be various materials that can improve the heat conduction effect between the chip and the first part 31, such as thermal grease. In a preferred embodiment, a bending part 34 is provided at the connection between the first part 31 and the second part 32, that is, the first part 31 and the second part 32 are connected through the bending part 34, so that there is a height difference between the first part 31 and the second part 32, thereby better adapting to the installation environment of the chip and ensuring the heat transfer effect.
[0065] In addition, an embodiment of the present invention further provides a floor sweeper, which includes a cleaning device, wherein the cleaning device is the above-mentioned cleaning device.
[0066] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0067] The cleaning device of the embodiment of the present invention includes: a housing 1, a cleaning assembly, a heating element 2, a heat-conducting member 3 and a driving member 4. Among them, the housing 1 has an air duct 10 for air circulation; the cleaning assembly is mounted on the housing 1 and is used for cleaning external objects; the heating element 2 is a functional component mounted on the housing 1, and the heating element 2 generates heat when working; the heat-conducting member 3 is in contact with the heating element 2, and at least part of the inner wall surface of the air duct 10 is the surface of the heat-conducting member 3; the driving member 4 drives the air flow in the air duct 10. For the cleaning device with this structural design, a heat-conducting member 3 in contact with the heating element 2 is designed, and at least part of the surface of the heat-conducting member 3 is used as the inner wall surface of the air duct 10 for direct heat dissipation. The heat generated by the heating element 2 during use is conducted to the heat-conducting member 3, and the driving member 4 drives the air flow in the air duct 10. During the process of the air flowing along the surface of the heat-conducting member 3, the heat on the heat-conducting member 3 can be taken away more efficiently. By designing the air duct 10, the heat-conducting member 3 and the driving member 4 with the above structures, the heat dissipation of the heating element 2 is effectively strengthened, the situation that the cleaning device fails due to the over-high temperature of the heating element during use is avoided, and the reliability of the cleaning device during use is effectively improved. It is especially suitable for use in high-temperature environments, long-term continuous operation, etc., and solves the technical problem of the poor working effect of the heating element inside the cleaning equipment in the related art.
