Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and more particularly to a cleaning module and cleaning equipment. Background Technology

[0002] With the widespread use of cleaning equipment, the functions of cleaning equipment are constantly increasing, and the number of functional modules is also increasing. Many functional modules are equipped with separate drive motors, which drive the functional modules to perform functions or to perform actions such as raising and lowering.

[0003] The overall shape of the cleaning equipment should remain largely unchanged, especially its height, to ensure ease of cleaning. The increase in functional modules leads to a more compact internal space. This compact space makes heat dissipation of the drive motor more difficult. The commonly used cooling solution for drive motors is fan cooling, but fan cooling requires a significant amount of space. Utility Model Content

[0004] This disclosure provides a cleaning module and cleaning equipment to improve the technical problem of heat dissipation difficulties of existing drive motors in the compact space of cleaning equipment.

[0005] The first aspect of this disclosure provides a cleaning module, which includes a module support, a drive motor, and a heat sink. The drive motor is mounted on the module support and drives the target object of the cleaning module. The heat sink is located on the outer periphery of the drive motor and contains liquid flowing through it. When the cleaning module is in operation, the direction perpendicular to the surface to be cleaned is defined as the height direction of the cleaning module. The drive motor has a clearance area on its upper side, and the heat sink is positioned to avoid this clearance area.

[0006] The drive motor of this disclosed cleaning module is used to drive the target object of the cleaning module. The target object includes, but is not limited to, cleaning components. For example, the drive motor can drive the cleaning components to perform cleaning; the drive motor can also drive the cleaning components to swing outwards, etc. The cleaning module includes a heat sink, which is disposed on the outer periphery of the drive motor. Liquid flows through the heat sink, thereby quickly carrying away the heat of the drive motor through the liquid in the heat sink, preventing the heat of the drive motor from accumulating near the drive motor, effectively improving the heat dissipation efficiency of the drive motor, and ensuring the working efficiency of the drive motor.

[0007] The drive motor has a clearance area on its upper side, where no heat pipe is installed. This reduces the space occupied by the drive motor and heat pipe in the vertical direction, avoiding an increase in the height of the cleaning module and saving height space for the cleaning equipment. This ensures effective heat dissipation for the drive motor while avoiding an increase in the height of the cleaning module, guaranteeing the convenience and accessibility of the cleaning equipment. It is also beneficial for the cleaning equipment to clean low areas, such as under sofas and beds.

[0008] In an exemplary embodiment of this disclosure, the highest point of the heat dissipation pipe in the circumferential direction of the clearance area is not higher than the highest point of the clearance area.

[0009] The heat dissipation pipe itself has a certain thickness or diameter. By ensuring that the highest point of the heat dissipation pipe around the clearance area is not higher than the highest point of the drive motor in the clearance area, it can be guaranteed that the heat dissipation pipe does not occupy the upper space of the clearance area, thus not occupying the height space of the cleaning equipment, and ensuring the height of the cleaning equipment and the convenience of cleaning.

[0010] In an exemplary embodiment of this disclosure, the heat dissipation pipe includes a first segment, a second segment, and a connecting segment. The first segment is disposed on one side of the circumferential direction of the clearance area; the second segment is disposed on the other side of the circumferential direction of the clearance area; and the connecting segment connects the first segment and the second segment.

[0011] By setting the heat dissipation pipe in multiple segments, with the first segment set on one side of the clearance area and the second segment set on the other side of the clearance area, compared with the conventional circumferential winding arrangement, the solution disclosed herein allows the heat dissipation pipe to avoid the clearance area, which not only ensures the heat dissipation of the drive motor, but also effectively reduces the occupation of height space.

[0012] The connecting section connects the first and second sections, ensuring that the heat dissipation pipe is a whole, facilitating the connection and arrangement of the heat dissipation pipe inlet and outlet, and ensuring the heat dissipation effect of the heat dissipation pipe on the drive motor.

[0013] In an exemplary embodiment of this disclosure, the clearance area covers the upper side of the drive motor; the connecting section is disposed at one end of the drive motor along the axial direction.

[0014] Some drive motors are used for lifting and lowering the cleaning module, so the space above the drive motor is more important and compact. By covering the upper side of the drive motor with a clearance area, the utilization of the space above the drive motor can be effectively guaranteed, and the heat pipes can be prevented from affecting the lifting and lowering of the drive motor and the cleaning module.

[0015] The connecting section is located at one end of the drive motor along its axial direction, thus avoiding obstruction of the upper space of the drive motor and minimizing its impact on that space. Projected along the axial direction of the drive motor, the highest point of the connecting section can be higher than, flush with, or lower than the highest point of the drive motor. Preferably, the highest point of the connecting section is not higher than the highest point of the drive motor, effectively ensuring sufficient space for the drive motor's vertical movement and preventing the connecting section from affecting its vertical motion.

[0016] In an exemplary embodiment of this disclosure, at least one end region on the upper side of the drive motor is not provided with a clearance area; the connecting segment is fitted to the end of the outer periphery of the drive motor and extends along the circumferential direction of the drive motor.

[0017] The clearance area does not cover at least one end of the upper side of the drive motor, thus facilitating the placement of the connecting section at the outer periphery of the drive motor and ensuring the continuity of the heat dissipation pipes. This reduces the space occupied above the drive motor, facilitating the design of the main body of the equipment above the drive motor, and also facilitates the placement of the connecting section, avoiding any impact on other areas.

[0018] In an exemplary embodiment of this disclosure, the first segment is wavy and affixed to one side of the circumferential direction of the avoidance area; the second segment is wavy and affixed to the other side of the axial direction of the avoidance area.

[0019] The first section's wavy design effectively increases the contact area between it and the drive motor, thereby improving heat dissipation efficiency. The wavy design also ensures the smooth flow of liquid within the first section, maintaining its flow velocity. Similarly, the wavy design of the second section effectively ensures both efficient heat dissipation for the drive motor and maintains the desired liquid flow velocity.

[0020] In an exemplary embodiment of this disclosure, the heat dissipation pipe includes a bonding section, which is cut along a plane perpendicular to the liquid flow direction within the bonding section, and the cross-section of the bonding section near the drive motor matches the surface of the drive motor.

[0021] The side of the bonding section closest to the drive motor matches the surface of the drive motor, thus making the bonding section in surface contact with the surface of the drive motor. This increases the contact area between the bonding section and the surface of the drive motor, giving the drive motor a larger heat transfer path, thereby effectively improving heat dissipation efficiency. At the same time, it can improve the uniformity of heat on the surface of the drive motor, improve the situation of local overheating on the surface of the drive motor, and reduce the maximum and average temperature of the drive motor surface.

[0022] In an exemplary embodiment of this disclosure, the heat dissipation pipe includes an inlet section and an outlet section. One end of the inlet section is connected to the bonding section, and the other end is configured to communicate with the water tank of the cleaning device; one end of the outlet section is connected to the bonding section, and the other end is connected to a spray head that sprays water onto the cleaning components of the cleaning module, or the other end is communicated with the water tank of the cleaning device.

[0023] The inlet and outlet sections are connected to both ends of the bonding section, allowing the liquid to flow out sequentially through the inlet section, bonding pipe, and outlet section. The outlet section can be connected to the spray head. A connecting pipe needs to be installed between the water tank and the spray head of the cleaning equipment. By using a heat dissipation pipe to connect the water tank and the spray head, a separate heat dissipation pipe is avoided, thus simplifying the heat dissipation pipe layout and reducing the space occupied by the cleaning equipment. At the same time, the heat dissipation pipe also absorbs heat from the drive motor, thereby increasing the water temperature or slowing down the cooling rate of the water, increasing the outlet water temperature of the spray head, achieving the effect of hot water mopping, and thus improving the cleaning effect.

[0024] The liquid outlet section can also be connected to the water tank of the cleaning equipment, so that the heat dissipation pipe and the water tank form a circulating water circuit, ensuring the flow of liquid in the heat dissipation pipe and ensuring the heat dissipation effect on the drive motor.

[0025] In an exemplary embodiment of this disclosure, the cleaning module includes a heat sink attached to the outside of the drive motor, the heat sink having a thermal conductivity greater than the heat dissipation coefficient of the drive motor housing; and a heat pipe attached to the side of the heat sink away from the drive motor.

[0026] By using heat sinks with high thermal conductivity, heat from the drive motor's housing surface is more easily absorbed by the heat sinks and carried away by the liquid inside the cooling pipes. Heat from areas of the drive motor without cooling pipes can also be quickly absorbed by the heat sinks, improving the uniformity of the drive motor's surface temperature, reducing localized heat buildup, and lowering both the maximum and average surface temperature of the drive motor.

[0027] A second aspect of this disclosure provides a cleaning device, which includes a device body and a cleaning module as described above, wherein the cleaning module is installed on the device body.

[0028] The cleaning equipment disclosed herein includes a cleaning module, which comprises a drive motor and a heat sink. The heat sink is disposed on the outer periphery of the drive motor, and liquid flows through the heat sink, effectively improving the heat dissipation efficiency of the drive motor and ensuring its working efficiency. A clearance area is provided on the upper side of the drive motor, where no heat sink is disposed, thereby reducing the space occupied by the drive motor and heat sink in the height direction and saving height space of the cleaning equipment.

[0029] The beneficial effects of this disclosure are:

[0030] The drive motor of this disclosed cleaning module is used to drive the target object of the cleaning module. The target object includes, but is not limited to, cleaning components. For example, the drive motor can drive the cleaning components to perform cleaning; the drive motor can also drive the cleaning components to swing outwards, etc. The cleaning module includes a heat sink, which is disposed on the outer periphery of the drive motor. Liquid flows through the heat sink, thereby quickly carrying away the heat of the drive motor through the liquid in the heat sink, preventing the heat of the drive motor from accumulating near the drive motor, effectively improving the heat dissipation efficiency of the drive motor, and ensuring the working efficiency of the drive motor.

[0031] The drive motor has a clearance area on its upper side, where no heat pipe is installed. This reduces the space occupied by the drive motor and heat pipe in the vertical direction, saving height space for the cleaning equipment. This ensures effective heat dissipation for the drive motor while avoiding increasing the height of the cleaning equipment, guaranteeing the convenience and accessibility of the cleaning equipment. It is also beneficial for the cleaning equipment to clean low areas, such as under sofas and beds. Attached Figure Description

[0047] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of the present disclosure. However, it will be apparent to those skilled in the art that embodiments of the present disclosure may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present disclosure.

[0048] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of this disclosure.

[0049] As cleaning equipment becomes increasingly feature-rich, so too do its functional modules. Many of these modules are equipped with individual drive motors, which power the modules to perform functions or to perform actions such as raising or lowering. During prolonged operation, these drive motors require constant cooling to maintain optimal operating temperatures and high efficiency. However, the limited space presents a significant challenge to heat dissipation in these motors.

[0050] Please see Figures 1 to 5 Therefore, this disclosure provides a cleaning module and cleaning equipment. The drive motor 310 is liquid-cooled by installing a heat sink 400 around its outer periphery, reducing the space required for heat dissipation. By defining a clearance area 311 on the upper side of the drive motor 310, the heat sink 400 is positioned to avoid this clearance area, effectively preventing the heat sink 400 from occupying space above the drive motor 310. This reduces the increase in the height of the cleaning module and the cleaning equipment, improving the ease of operation and accessibility of the cleaning equipment.

[0051] Please see Figures 1 to 5The first aspect of this disclosure provides a cleaning module, which includes a module support 100, a drive motor 310, and a heat sink 400. The module support 100 provides mounting positions and space for some components of the cleaning module. The drive motor 310 is disposed on the module support 100 and drives the target object of the cleaning module. The heat sink 400 is disposed on the outer periphery of the drive motor 310 and contains liquid flowing through it; wherein, with the direction perpendicular to the surface to be cleaned when the cleaning module is in the working state as the height direction of the cleaning module, the upper side of the drive motor 310 has a clearance area 311, and the heat sink 400 is disposed to avoid the clearance area 311.

[0052] The drive motor 310 of this cleaning module is used to drive the target object of the cleaning module. The target object includes, but is not limited to, the cleaning component 200. For example, the drive motor 310 can drive the cleaning component 200 to perform cleaning; the drive motor 310 can also drive the cleaning component 200 to swing outward, etc. Taking the cleaning component 200 as the target object, the module support 100 has a receiving cavity formed on the side facing the surface to be cleaned. The cleaning component 200 is disposed in the receiving cavity and at least partially protrudes out of the receiving cavity, so that the cleaning component 200 interferes with the surface to be cleaned to clean the surface. The drive motor 310 is usually disposed on the side of the module support 100 away from the cleaning component 200. The drive motor 310 drives the cleaning component 200 to move through a transmission structure, for example, the drive motor 310 drives the cleaning component 200 to move through a gear transmission structure. The cleaning module is installed below the cleaning equipment. When the cleaning equipment is not in operation or needs to cross obstacles, the cleaning module needs to be lifted. If the height of the cleaning module is increased, it is easy for the cleaning module to interfere with the main body of the cleaning equipment during the lifting process, or the height of the main body of the equipment needs to be increased.

[0053] The heat dissipation pipe 400 of the cleaning module disclosed herein is disposed on the outer periphery of the drive motor 310. The upper side of the drive motor 310 has a clearance area 311, which is a defined area on the upper part of the drive motor 310. The heat dissipation pipe 400 is not disposed in the clearance area 311, thereby reducing the space occupied by the drive motor 310 and the heat dissipation pipe 400 in the height direction, avoiding increasing the height of the cleaning module, and preventing interference between the cleaning module and the main body of the equipment during the lifting process. It does not require increasing the height of the main body of the equipment, thereby saving the height space of the cleaning equipment, ensuring the convenience and passability of the cleaning equipment, and facilitating the cleaning equipment to clean low areas, such as under sofas and under beds.

[0054] The heat pipe 400 contains liquid flowing through it. The specific heat capacity of the liquid is higher than that of air, and the liquid in the heat pipe 400 can quickly carry away the heat of the drive motor 310, preventing the heat of the drive motor 310 from accumulating near the drive motor 310. This effectively improves the heat dissipation efficiency of the drive motor 310 and ensures the working efficiency of the drive motor 310.

[0055] Please see Figure 3 In one embodiment, the highest point of the heat dissipation pipe 400 circumferentially in the clearance area 311 is not higher than the highest point of the clearance area 311.

[0056] The heat pipe 400 itself has a certain thickness or diameter. Since the highest point of the heat pipe 400 in the circumference of the clearance area 311 is not higher than the highest point of the drive motor 310 in the clearance area 311, it can be ensured that the heat pipe 400 does not occupy the upper space of the clearance area 311 at all, thereby not increasing the height of the cleaning module, not occupying the height space of the cleaning equipment, and ensuring the cleaning convenience of the cleaning equipment.

[0057] For example, the highest point of the heat dissipation pipe 400 circumferentially in the clearance area 311 can be flush with the highest point of the drive motor 310 in the clearance area 311, and the highest point of the heat dissipation pipe 400 circumferentially in the clearance area 311 can also be lower than the highest point of the drive motor 310 in the clearance area 311.

[0058] Of course, as an alternative, the highest point of the heat dissipation pipe 400 circumferentially in the clearance area 311 can also be higher than the highest point of the drive motor 310 in the clearance area 311. For example, the heat dissipation pipe 400 circumferentially in the clearance area 311 can be set at the edge of the clearance area 311. The heat dissipation pipe 400 has a certain thickness, so that the highest point of the heat dissipation pipe 400 is slightly higher than the highest point of the drive motor 310 in the clearance area 311. Compared with setting the heat dissipation pipe 400 in the clearance area 311, the height occupied after setting the heat dissipation pipe 400 at the edge of the clearance area 311 is still smaller. This can reduce the increase in the height of the cleaning module after setting the heat dissipation pipe 400, thereby reducing the space occupied by the height of the cleaning equipment.

[0059] Please see Figure 2 , Figure 4 and Figure 5 In one embodiment, the heat dissipation pipe 400 includes a first segment 440, a second segment 450, and a connecting segment 460. The first segment 440 is disposed on one side of the circumferential direction of the clearance area 311. The second segment 450 is disposed on the other side of the circumferential direction of the clearance area 311. The connecting segment 460 connects the first segment 440 and the second segment 450.

[0060] By setting the heat dissipation pipe 400 in multiple segments, with the first segment 440 set on one side of the circumference of the clearance area 311 and the second segment 450 set on the other side of the circumference of the clearance area 311, compared with the conventional circumferential winding arrangement, the solution disclosed herein allows the heat dissipation pipe 400 to avoid the clearance area 311, which not only ensures the heat dissipation of the drive motor 310, but also effectively reduces the occupation of height space.

[0061] The connecting section 460 connects the first section 440 and the second section 450, ensuring that the heat pipe 400 is a whole, facilitating the connection and arrangement of the inlet and outlet of the heat pipe 400, and ensuring the heat dissipation effect of the heat pipe 400 on the drive motor 310.

[0062] In one embodiment, the clearance area 311 covers the upper side of the drive motor 310. The connecting section 460 is disposed at one end of the drive motor 310 in the axial direction.

[0063] Some drive motors 310 will rise and fall with the cleaning module. Therefore, the space above the drive motors 310 is more important and compact. By covering the upper side of the drive motors 310 with the clearance area 311, the utilization of the space above the drive motors 310 can be effectively guaranteed, and the heat pipes 400 can be prevented from affecting the rise and fall of the drive motors 310 and the cleaning module.

[0064] The connecting segment 460 is disposed at one end of the drive motor 310 along the axial direction. The connecting segment 460 can be disposed in various ways. For example, the connection point of the connecting segment 460 and the first segment 440 extends along the axial direction of the drive motor 310 to the outer side of the end of the drive motor 310, and then extends along the axial direction of the drive motor 310 to connect with the second segment 450; or, the connection point of the connecting segment 460 and the first segment 440 extends along the axial direction of the drive motor 310 to the outer side of the end of the drive motor 310, then extends horizontally, and then extends along the axial direction of the drive motor 310 to connect with the second segment 450, etc.

[0065] The connecting section 460 can abut against the end face of the drive motor 310 to reduce the temperature of the end face of the drive motor 310 and also reduce the space occupied by the drive motor 310 and the heat pipe 400 in the axial direction of the drive motor 310. Alternatively, the connecting section 460 may not abut against the end face of the drive motor 310, and there may be a gap between the connecting section 460 and the end face of the drive motor 310 to facilitate the arrangement of the heat pipe 400 and reduce the assembly requirements of the heat pipe 400 and the drive motor 310.

[0066] The connecting segment 460 is located at one end of the drive motor 310 along the axial direction, which can avoid obstructing the upper space of the drive motor 310 and reduce the space occupied by it. Projected along the axial direction of the drive motor 310, the high point of the connecting segment 460 can be higher than, flush with, or lower than the high point of the drive motor 310. Preferably, the high point of the connecting segment 460 is not higher than the high point of the drive motor 310, thereby effectively ensuring sufficient space for the drive motor 310 to move up and down, and preventing the connecting segment 460 from affecting the up and down movement of the drive motor 310.

[0067] Please see Figure 4 and Figure 5 In another embodiment, at least one end region on the upper side of the drive motor 310 is not provided with a clearance area 311. The connecting segment 460 is fitted to the end of the outer periphery of the drive motor 310 and extends circumferentially along the drive motor 310.

[0068] The clearance area 311 does not cover at least one end of the upper side of the drive motor 310. The connecting section 460 is located at the end of the outer peripheral surface of the drive motor 310, facilitating the arrangement of the connecting section 460. This ensures the continuity of the heat dissipation pipe 400. It reduces the space occupied above the drive motor 310, facilitating the design of the main body of the equipment above the drive motor 310, and also facilitates the arrangement of the connecting section 460, avoiding any impact on other areas.

[0069] Please see Figure 4 In one embodiment, the first segment 440 is affixed in a wavy shape to one side of the circumference of the avoidance area 311.

[0070] The first segment 440 is designed in a wave shape, which effectively increases the contact area between the first segment 440 and the drive motor 310, thereby improving the heat dissipation efficiency of the drive motor 310. The wave shape also ensures the flowability of the liquid in the first segment 440 and maintains the liquid flow speed, thereby reducing the temperature of the liquid in the first segment 440 and improving the heat dissipation efficiency of the drive motor 310.

[0071] Please see Figure 5 The second section 450 is wavy and attached to the other side of the axial direction of the clearance area 311. Similarly, the wavy arrangement of the second section 450 can effectively ensure the heat dissipation efficiency of the drive motor 310 and also ensure the flow speed of the liquid.

[0072] Of course, as some alternatives, the first segment 440 can also be of other shapes. For example, the first segment 440 can be arranged to extend reciprocally along the axial direction of the drive motor 310 to ensure the contact area between the first segment 440 and the drive motor 310. Similarly, the second segment 450 can also be arranged in other ways to ensure the contact area with the drive motor 310.

[0073] Please see Figure 3 In one embodiment, the heat pipe 400 includes a bonding section 410, which is cut along a plane perpendicular to the liquid flow direction within the bonding section 410. The cross-section of the bonding section 410 near the drive motor 310 matches the surface of the drive motor 310.

[0074] The side of the bonding section 410 closest to the drive motor 310 matches the surface of the drive motor 310, thereby making the bonding section 410 and the surface of the drive motor 310 in surface contact. This increases the contact area between the bonding section 410 and the surface of the drive motor 310, giving the drive motor 310 a larger heat transfer path and effectively improving heat dissipation efficiency. At the same time, it can improve the uniformity of heat on the surface of the drive motor 310, improve the situation of local overheating on the surface of the drive motor 310, and reduce the maximum and average temperatures of the surface of the drive motor 310.

[0075] For example, the cross-section of the fitting section 410 can be a rectangle, an ellipse, an oblong shape, or a shape that can match the surface of the drive motor 310.

[0076] For example, the bonding section 410 is a flat tube, and the large surface of the flat tube is in contact with the drive motor 310. This ensures both the contact area with the drive motor 310 and the heat dissipation efficiency, while also reducing the diameter of the bonding section 410, reducing the flow rate and increasing the flow velocity. At the same time, it can also reduce the space occupied by the bonding section 410, which is conducive to the miniaturization and integration of the cleaning module and the cleaning equipment.

[0077] Please see Figure 3 In one embodiment, the heat pipe 400 includes an inlet section 420 and an outlet section 430.

[0078] One end of the liquid inlet section 420 is connected to the bonding section 410, and the other end is configured to communicate with the water tank of the cleaning equipment. The other end is connected to a spray head that sprays water to the cleaning component 200 of the cleaning module.

[0079] The inlet section 420 and outlet section 430 are connected to both ends of the bonding section 410, respectively, allowing the liquid to flow out sequentially through the inlet section 420, the bonding pipe, and the outlet section 430. The outlet section 430 can be connected to the spray head. A connecting pipe needs to be installed between the water tank and the spray head of the cleaning equipment. By utilizing the heat dissipation pipe 400 as part of the connecting pipe between the water tank and the spray head, the separate pipe arrangement for the heat dissipation pipe 400 is avoided, simplifying its placement and reducing the space occupied by the cleaning equipment. Simultaneously, the heat dissipation pipe 400 also absorbs heat from the drive motor 310, thereby increasing the water temperature or slowing down the cooling rate, increasing the outlet water temperature of the spray head, achieving the effect of hot water mopping, and thus improving the cleaning effect.

[0080] In another embodiment, one end of the liquid outlet section 430 is connected to the bonding section 410, and the other end is connected to the water tank of the cleaning equipment.

[0081] The liquid outlet section 430 is connected to the water tank of the cleaning equipment, so that the heat dissipation pipe 400 and the water tank form a circulating water circuit. The water in the water tank carries away the heat from the drive motor 310 through the heat dissipation pipe 400 and flows into the water tank, ensuring the flow of liquid in the heat dissipation pipe 400 and ensuring the heat dissipation effect on the drive motor 310.

[0082] In one embodiment, the cleaning module includes a heat sink 500, which is attached to the outside of the drive motor 310. The thermal conductivity of the heat sink 500 is greater than the heat dissipation coefficient of the housing of the drive motor 310. A heat pipe 400 is attached to the side of the heat sink 500 away from the drive motor 310.

[0083] By incorporating a heat sink 500 with a high thermal conductivity, heat from the surface of the drive motor 310's housing is more easily absorbed by the heat sink 500 and carried away by the liquid within the heat pipe 400. Heat in areas of the drive motor 310 where the heat pipe 400 is not located can also be quickly absorbed by the heat sink 500, improving the uniformity of the drive motor 310's surface temperature, mitigating localized heat buildup, and reducing the highest and average surface temperatures of the drive motor 310.

[0084] In one embodiment, a heat sink 500 is also attached to the drive motor 310 in the clearance area 311. The heat sink 500 is relatively thin, which has little impact on the height of the cleaning module. By attaching the heat sink 500 to the clearance area 311, the heat of the drive motor 310 in the clearance area 311 can be dissipated through the heat sink 500 and then carried away by the liquid in the heat dissipation pipe 400, avoiding heat accumulation in the clearance area 311, improving the heat dissipation effect of the drive motor 310, and ensuring that the drive motor 310 has high working efficiency.

[0085] A second aspect of this disclosure provides a cleaning device, which includes a device body and a cleaning module as described above, wherein the cleaning module is installed on the device body.

[0086] The cleaning equipment disclosed herein can be self-propelled cleaning equipment with a self-propelled system, such as a mopping robot, a sweeping and mopping robot, or a sweeping robot; it can also be manually driven cleaning equipment such as a floor scrubber.

[0087] The cleaning equipment disclosed herein includes a cleaning module, which comprises a drive motor 310 and a heat sink 400. The heat sink 400 is disposed on the outer periphery of the drive motor 310, and liquid flows through the heat sink 400, effectively improving the heat dissipation efficiency of the drive motor 310 and ensuring its working efficiency. The drive motor 310 has a clearance area 311 on its upper side, where the heat sink 400 is not disposed, thereby reducing the space occupied by the drive motor 310 and the heat sink 400 in the height direction and saving height space of the cleaning equipment.

[0088] The cleaning module and equipment disclosed herein effectively improve the heat dissipation efficiency of the drive motor 310 by setting a heat dissipation pipe 400 on the outer periphery of the drive motor 310, through which liquid flows, thus ensuring the working efficiency of the drive motor 310. The drive motor 310 has a clearance area 311 on its upper side, where the heat dissipation pipe 400 is not installed, thereby reducing the space occupied by the drive motor 310 and the heat dissipation pipe 400 in the height direction, saving height space for the cleaning equipment. This ensures effective heat dissipation for the drive motor 310 while avoiding increasing the height of the cleaning equipment, guaranteeing the convenience and accessibility of cleaning. Therefore, this disclosure effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.

[0089] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the claims of this disclosure.
