Detailed Implementation
[0052] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0053] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0054] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.
[0055] Taking floor scrubbers as an example, during normal operation, the battery pack of cleaning equipment, especially when operating at high current, is prone to excessively rapid temperature rise, making it easy for the battery pack temperature to reach the temperature rise protection point. Therefore, the discharge capacity and the overall battery life of the machine should be considered.
[0056] To address this, existing technologies typically employ a special phase change material to completely encapsulate the battery cell, absorbing the heat released by the cell through the material's properties. However, on one hand, because the heat absorption capacity of phase change materials is limited, once the absorbed and stored heat reaches saturation, the material will release the absorbed and stored heat in reverse, causing the battery cells to remain in a high-temperature insulation state for extended periods, increasing the heat dissipation burden on the battery pack, especially at the cell level. Furthermore, phase change materials are generally quite expensive, which can easily increase the overall cost of the device.
[0057] To address the aforementioned technical problems, the present invention provides a body 10. The body 10 can be applied to various electrical appliances, and is particularly suitable for various cleaning equipment 1. The cleaning equipment 1 includes, for example, floor scrubbers, sweepers, and window cleaners. For ease of understanding, the following embodiments will use the application of the body 10 in a floor scrubber as an example.
[0058] Please see Figures 1 to 7 The attached figure shows a specific embodiment of the machine body 10 provided by the present invention applied in a floor scrubber.
[0059] Please refer to the following first. Figures 1 to 4 The present invention provides a body 10 including a main body 100 and a cooling fan 200. The main body 100 includes a housing 110 and a battery pack 120 disposed on the housing 110. The housing 110 has an air inlet 111 and an air outlet 112. The main body 100 also includes a cooling duct 130 connecting the air inlet 111 and the air outlet 112, the cooling duct 130 at least partially penetrating the battery pack 120. The cooling fan 200 is disposed at the air inlet 111 and / or the air outlet 112 and is used to drive airflow through the cooling duct 130.
[0060] In the body 10 provided by this invention, a heat dissipation duct 130 is disposed through the battery pack 120, allowing the heat dissipation airflow flowing through the heat dissipation duct 130 to exchange heat with the interior of the battery pack 120 during its flow. This helps to reduce the heat loss in the battery pack 120, specifically targeting areas with greater heat dissipation needs, thereby optimizing the overall heat dissipation effect of the battery pack 120. The heat dissipation fan 200 drives the heat dissipation airflow within the heat dissipation duct 130, which helps to increase the flow rate and volume of the heat dissipation airflow, and ensures that the heat dissipation airflow flowing through the heat dissipation duct 130 is orderly and efficient. This ensures that the heat dissipation airflow flowing through the battery pack 120 is a low-temperature, fast-flowing, and high-volume effective heat dissipation airflow, thereby further enhancing the heat exchange intensity of the battery pack 120.
[0061] This application does not limit the specific form of the housing 110. Depending on different application requirements, the housing 110 can be specifically manifested as one or more connected plate structures, support structures, box structures, block structures, etc.
[0062] For example, attached Figures 1 to 4 As shown, in one embodiment, the housing 110 can be generally box-shaped to define a cavity structure (i.e., the battery cavity 113 and motor cavity 117 hereinafter referred to as the cavity). The battery pack 120 is housed within the battery cavity 113, facilitating protection and isolation of the battery pack 120 from various orientations by the housing 110. Accordingly, the housing 110 can directly form the battery cavity 113 during injection molding; alternatively, the housing 110 includes at least two shell plate structures, at least one of which has a groove, and the other shell plate covers the opening of the groove structure, together enclosing and defining the battery cavity 113. This facilitates the disassembly and replacement of the battery pack 120 at the battery cavity 113 when the two shell plate structures are separated, enabling routine maintenance of the battery pack 120; and when the two shell plate structures are joined, they facilitate the enclosure of a relatively closed battery cavity 113, providing good protection for the battery pack 120.
[0063] Next, the connection method and installation position of the battery pack 120 and the housing 110 are not limited, and can be adjusted according to the specific form of the housing 110 and the form of protection provided by the housing 110 to the battery pack 120. The battery pack 120 can be detachably connected to the housing 110, specifically by one or more of the following methods: screw fixing, adhesive fixing, magnetic fixing, and snap fixing; of course, the battery pack 120 can also be non-detachably connected to the housing 110, specifically by welding fixing.
[0064] The main body 100 defines a heat dissipation duct 130, which at least partially penetrates the battery pack 120. It is understood that in one embodiment, the heat dissipation duct 130 may be defined solely by the battery pack 120 within the main body 100. In this case, the entire heat dissipation duct 130 penetrates the battery pack 120, i.e., a through-hole is formed along a certain dimensional direction of the battery pack 120, and this through-hole constitutes the heat dissipation duct 130. In another embodiment, the heat dissipation duct 130 may be jointly defined by the housing 110 and the battery pack 120. In this case, a portion of the heat dissipation duct 130 penetrates the battery pack 120 as described above, while the remaining portion is defined by the cavity wall of the housing 110 or other structures.
[0065] It should be noted that when the heat dissipation duct 130 is jointly defined by the housing 110 and the battery pack 120, for ease of understanding, the heat dissipation duct 130 is defined as including a first heat dissipation duct 131 and a second heat dissipation duct 132 that are connected. The first heat dissipation duct 131 is defined by the housing 110 alone or by the housing 110 and the battery pack 120 together; the second heat dissipation duct 132 is defined by the battery pack 120 and extends through it. It is understood that since the second heat dissipation duct 132 extends through the battery pack 120, its main function is to establish a heat exchange connection with the interior of the battery pack 120, allowing the airflow flowing through the second heat dissipation duct 132 to effectively dissipate heat from the interior of the battery pack 120 (e.g., at the individual battery cells 121 described below). The function of the first heat dissipation duct 131 can be configured according to the actual application, for example:
[0066] In one embodiment, the first heat dissipation duct 131 can be used to guide and change the direction of the heat dissipation airflow entering or exiting the second heat dissipation duct 132. At this time, the extension direction of the first heat dissipation duct 131 can be set to a linear shape as required, such as a straight line or a curved shape with at least one bend, according to actual needs.
[0067] Alternatively, in one embodiment, the first heat dissipation duct 131 can be used to accelerate or decelerate the heat dissipation airflow entering or exiting the second heat dissipation duct 132. In this case, the ventilation cross-section of the first heat dissipation duct 131 can be appropriately increased or decreased compared to the ventilation cross-section of the second heat dissipation duct 132.
[0068] Alternatively, in one embodiment, the first heat dissipation duct 131 can be used to adjust the temperature, humidity, air pressure, and airflow composition of the heat dissipation airflow entering or exiting the second heat dissipation duct 132. In this case, additional materials such as a temperature-changing material layer, a water-absorbing or moisturizing material layer, or a target component slow-release layer can be added to the first heat dissipation duct 131. Adjustment devices for temperature, humidity, and air pressure can also be added. No limitations are imposed.
[0069] In this embodiment, as described above, when the heat dissipation duct 130 includes a first heat dissipation duct 131 and a second heat dissipation duct 132 that are connected, and the housing 110 defines the first heat dissipation duct 131, and the battery pack 120 has the second heat dissipation duct 132 extending through it, at least one surface of the battery pack 120 is in heat exchange connection with the first heat dissipation duct 131. Specifically, the heat exchange connection can be a contact connection or a non-contact connection. For example, at least one surface of the battery pack 120 extends into the first heat dissipation duct 131 for heat exchange; or the wall of the heat dissipation duct 130 constituting the first heat dissipation duct 131 is made of a thermally conductive material, and the battery pack 120 makes heat exchange contact with the wall of the heat dissipation duct 130; or at least one surface of the battery pack 120 directly constitutes at least one wall of the first heat dissipation duct 130, etc. In this way, when the cooling airflow flows through the first cooling air duct 131, the heat exchange connection between the first cooling air duct 131 and the battery pack 120 can dissipate heat on at least one side of the surface of the battery pack 120. Combined with the setting of the second cooling air duct 132, the outer wall and the interior of the battery pack 120 can be well and timely cooled, which helps to improve the overall heat dissipation effect of the battery pack 120.
[0070] Based on the above, in practical applications, there are various ways in which at least one surface of the battery pack 120 directly forms at least one wall of the first heat dissipation duct 131. Specifically, in one embodiment, when a battery cavity 113 is formed within the housing 110, the battery pack 120 is housed within the battery cavity 113 and spaced apart from at least one wall of the battery cavity 113, thus defining the first heat dissipation duct 131 at the spaced interval. In this way, the first heat dissipation duct 131 is jointly defined by the battery pack 120 and the cavity wall of the battery cavity 113, allowing the outer surface of the battery pack 120 to directly exchange heat with the cooling airflow flowing through the first heat dissipation duct 131. This improves heat exchange efficiency and eliminates the need for additional wall structures on the corresponding side of the first heat dissipation duct 131, simplifying the structure at the first heat dissipation duct 131 and making the battery pack 120 and housing 110 structurally compact.
[0071] Based on any of the above embodiments, in this application, at least one of the first heat dissipation duct 131 and the second heat dissipation duct 132 is arranged in series with multiple such ducts; and / or at least one of the first heat dissipation duct 131 and the second heat dissipation duct 132 is arranged in parallel with multiple such ducts.
[0072] Taking the first heat dissipation duct 131 as an example, it can be understood that the first heat dissipation duct 131 is generally longitudinally elongated and has at least two ports (defined as inlet port and outlet port for ease of understanding). Multiple first heat dissipation ducts 131 are connected in series, meaning that the outlet port of the first heat dissipation duct 131 located on the rear side of the airflow direction is connected to the inlet port of the first heat dissipation duct 131 located on the front side of the airflow direction. This allows the cooling airflow to flow sequentially and unidirectionally through each first heat dissipation duct 131, facilitating the orderly flow of cooling airflow within each first heat dissipation duct 131. Multiple second heat dissipation ducts 132 are connected in parallel, meaning that the inlets of each first heat dissipation duct 131 are connected to each other or to the same air outlet (e.g., air inlet 111 in the following description), and the outlet ports of each first heat dissipation duct 131 are connected to each other or to the same air outlet (e.g., air outlet 112 in the following description), allowing the cooling airflow to circulate independently along each first heat dissipation duct 131. Since this application does not limit the extension shape of the heat dissipation duct 130 segment located between its inlet and outlet ports of each of the parallel first heat dissipation ducts 131, the heat dissipation airflow flowing through each of the first heat dissipation ducts 131 can exchange heat on the outer surface of the battery pack 120 at various locations according to the extension shape of the corresponding first heat dissipation duct 131.
[0073] The configuration of the second heat dissipation duct 132 can be referenced to that of the first heat dissipation duct 131, and will not be elaborated here. Specifically, when multiple first heat dissipation ducts 131 and multiple second heat dissipation ducts 132 are configured, at least one of the multiple first heat dissipation ducts 131 is connected to at least one of the second heat dissipation ducts 132, or at least one of the multiple first heat dissipation ducts 131 is connected to each of the second heat dissipation ducts 132.
[0074] Based on any of the above embodiments, in specific applications, the heat dissipation duct 130 can be a closed annular heat dissipation duct 130, which means that the heat dissipation airflow circulates repeatedly within the entire heat dissipation duct 130. By configuring the structure and orientation of the first heat dissipation duct 131 and the second heat dissipation duct 132, or by additionally configuring, for example, temperature regulating components, it can be ensured that the temperature of the heat dissipation airflow entering the first heat dissipation duct 131 at least meets the heat dissipation requirements of the outer surface of the battery pack 120, and the temperature of the heat dissipation airflow entering the second heat dissipation duct 132 at least meets the heat dissipation requirements of the interior of the battery pack 120.
[0075] In another embodiment, please refer to Figures 2 to 4The heat dissipation duct 130 is disposed through the main body 100, and an air inlet 111 and an air outlet 112 are formed on the main body 100 to connect with the external environment. In this way, the heat dissipation air with a lower temperature in the external environment enters the heat dissipation duct 130 through the air inlet 111, and is discharged to the external environment through the air outlet 112 after flowing through the heat dissipation duct 130. By using the external environment to regulate and compensate for the temperature of the heat dissipation air, the burden of additional functions on the body 10 can be reduced as much as possible, and the structure of the body 10 can be kept from becoming too complicated.
[0076] In addition, the body 10 of this application also includes a cooling fan 200. The cooling fan 200 is a device used to drive the airflow within the cooling duct 130. The cooling fan 200 can adjust at least one of the flow rate, direction, and volume of the cooling airflow, allowing the airflow to flow at the required speed, direction, and volume, thus achieving good heat dissipation for the battery pack 120. The cooling fan 200 generally has an intake side and an exhaust side. Depending on whether it primarily operates on the intake or exhaust side, the cooling fan 200 can be further classified as an exhaust fan or a blower, etc.
[0077] Specifically, in one embodiment, the cooling fan 200 can be located at the air outlet 112, with the suction side facing the cooling duct 130. This helps to quickly and timely discharge the heat-exchanged airflow outside the cooling duct 130 while driving the cooling airflow through it. And / or, in one embodiment, the cooling fan 200 can be located at the air inlet 111, with the air outlet facing the cooling duct 130. This helps to quickly and timely provide sufficient cooling airflow to the cooling duct 130 to meet its cooling requirements while driving the cooling airflow through it.
[0078] Next, please refer to Figure 4In one embodiment, the first heat dissipation duct 131 and the second heat dissipation duct 132 are connected sequentially, i.e., in series. The first heat dissipation duct 131 is connected to the air inlet 111, and the second heat dissipation duct 132 is connected to the air outlet 112. The heat dissipation fan 200 has an air intake side, which is located at the air outlet 112, and the air intake side faces the second heat dissipation duct 132. Thus, driven by the heat dissipation fan 200, the cooling airflow from the external environment enters the first heat dissipation duct 131 from the air inlet 111, exchanges heat on the outer surface of the battery pack 120, and then enters the second heat dissipation duct 132 to continue exchanging heat on the interior of the battery pack 120, finally being discharged to the external environment from the air outlet 112. At this time, the first heat dissipation duct 131 and the second heat dissipation duct 132 can provide secondary heat dissipation for the battery pack 120. Because the heat generated inside the battery pack 120 tends to accumulate within the limited internal space and cannot dissipate, the temperature inside the battery pack 120 is higher than the temperature outside. After the cooling airflow dissipates heat from the outer surface of the battery pack 120 through the first heat dissipation duct 131, it can still enter the second heat dissipation duct 132 to meet the internal heat dissipation needs of the battery pack 120, ensuring an overall improvement in the heat dissipation effect of the battery pack 120.
[0079] Specifically, in one embodiment, the housing 110 includes a first housing plate 114 and a second housing plate 115 arranged opposite to each other, and a third housing plate 116 connecting the first housing plate 114 and the second housing plate 115. The air inlet 111 and the air outlet 112 are spaced apart on the first housing plate 114, specifically, the spaced apart in any dimensional direction. The battery pack 120 is spaced apart from the second housing plate 115 and the third housing plate 116 respectively, to define two sequentially connected first heat dissipation air ducts 131. The second heat dissipation air duct 132 extends between the first housing plate 114 and the second housing plate 115. In this way, the heat dissipation airflow entering the air inlet 111 flows sequentially through the two first heat dissipation air ducts 131, and after exchanging heat with at least two outer surfaces of the battery pack 120, it is guided to the first heat dissipation air duct 131 and continues to exchange heat with the interior of the battery pack 120. The arrangement of the first shell plate 114, the second shell plate 115, and the third shell plate 116 helps to extend the overall length of the heat dissipation duct 130 as much as possible within the limited space of the battery cavity 113, while minimizing the reverse flow of heat dissipation airflow within the heat dissipation duct 130. This helps to increase the total heat exchange area of the heat dissipation airflow on the battery pack 120 and optimize the overall heat dissipation effect of the heat dissipation airflow on the battery pack 120.
[0080] In a specific layout, in one embodiment, the orthographic projection of the port of the first heat dissipation duct 131 on the first shell plate 114 can be directly designed to at least partially coincide with the air inlet 111. That is, the port of the first heat dissipation duct 131 is basically directly opposite the air inlet 111, so that the port of the first heat dissipation duct 131 can be directly connected to the air inlet 111, and the heat dissipation airflow sent in by the air inlet 111 can be at least partially guided into a heat dissipation duct 130.
[0081] Alternatively, in one embodiment, when the orthographic projection of the port of the first heat dissipation duct 131 on the first shell plate 114 is offset from the air inlet 111, that is, when the port of the first heat dissipation duct 131 is misaligned with the air inlet 111, the body 10 further includes a guide plate 300, which extends obliquely from the air inlet 111 toward the port of the first heat dissipation duct 131. The misalignment can be arbitrary in any dimension or direction; the tilt angle of the guide plate 300 is related to the orientation of both the air inlet 111 and the port of the first heat dissipation duct 131; the extension length of the guide plate 300 can be adjusted according to actual needs, and can be simply set between the air inlet 111 and the port of the first heat dissipation duct 131, or can continue to extend along the extension direction of the first heat dissipation duct 131 to the required length. The arrangement of the guide plate 300 helps to ensure the smooth flow of the heat dissipation airflow and avoids disordered flow of the heat dissipation airflow within the battery cavity 113, thus preventing turbulence.
[0082] In the above embodiment, the second heat dissipation duct 132 is defined by the battery pack 120. For details, please refer to... Figures 5 to 7 In one embodiment, the battery pack 120 includes a plurality of battery cells 121 and a mounting bracket 122 connecting the plurality of battery cells 121, with a second heat dissipation duct 132 defined between at least two battery cells 121. Specifically, the axial direction of the battery cells 121 extends toward and away from the air inlet 111 or the air outlet 112 connected to them, the second heat dissipation duct 132 is defined between at least two battery cells 121, and the cooling fan 200 is located at one axial end of the battery cell 121.
[0083] The battery cell 121 is generally cylindrical. When multiple battery cells 121 are arranged in a set manner, there is at least a gap between two adjacent battery cells 121. At this time, the gap between any two battery cells 121 can be set as a second heat dissipation channel 132 as needed, so that the second heat dissipation channel 132 is close enough to the battery cell 121, thereby enabling targeted heat dissipation and cooling of the battery cell 121.
[0084] Furthermore, in one embodiment, the battery pack 120 further includes a heat dissipation bracket 123 connected to the mounting bracket 122 and / or the battery cell 121. The heat dissipation bracket 123 is made of a phase change material. A plurality of battery cells 121 are arranged around the outer periphery of the heat dissipation bracket 123. The heat dissipation bracket 123 extends toward at least two adjacent battery cells 121. The heat dissipation bracket 123 is provided with a second heat dissipation duct 132. The heat dissipation bracket 123, utilizing the heat absorption characteristics of its phase change material, can pre-dissipate heat from the battery cell 121 to a certain extent. By incorporating a first heat dissipation duct 131 on the heat dissipation bracket 123, the airflow within it works in conjunction with the phase change characteristics of the heat dissipation bracket 123 at each battery cell 121, achieving better heat dissipation within the battery pack 120. Furthermore, the airflow within the first heat dissipation duct 131 also dissipates heat from the heat dissipation bracket 123 itself. This ensures that when the heat dissipation bracket 123 reaches heat absorption saturation as described above, it maintains this state or cools down, preventing the heat dissipation bracket 123 from releasing heat back to the battery cell 121. By positioning the heat dissipation bracket 123 and the first heat dissipation duct 131 near the center of each battery cell 121, a limited number of these ducts can more evenly and stably dissipate heat from each battery cell 121.
[0085] In one embodiment, the housing 110 includes a third housing plate 116 that divides the interior of the housing 110 into a battery cavity 113 and a motor cavity 117. The battery pack 120 is housed within the battery cavity 113, and the battery pack 120 is spaced from the third housing plate 116 to define at least a portion of the first heat dissipation duct 131 (i.e., the portion of the first heat dissipation duct 131 located at the bottom of the battery pack 120). The body 10 also includes a motor 400, which is housed within the motor cavity 117. A connection port may be provided on the third housing plate 116 for wiring to the motor 400 and the battery pack 120.

The control device is electrically connected to the cooling fan 200 to control the operation of the cooling fan 200, realizing intelligent automation of heat dissipation for the battery pack 120 in the cleaning device 1.
[0088] In the above description, the control device is electrically connected to the cooling fan 200. The control device may include: a processor, such as a CPU; a communication bus; a user interface; a network interface; and memory. The communication bus is used to enable communication between these components.

The network interface may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory may be high-speed RAM or stable, non-volatile memory, such as a disk drive. Alternatively, the memory may be a storage device independent of the aforementioned processor.
[0089] Those skilled in the art will understand that the above-described structure does not constitute a limitation on the control device, and may include more or fewer components, or combine certain components, or have different component arrangements.
[0090] The memory, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a control program for the cleaning device 1.
[0091] The control device calls the control program of cleaning device 1 stored in the memory through the processor and performs the following operations:
[0092] Obtain the target operating mode of cleaning equipment 1;
[0093] When the target working mode is determined to be the first preset working mode, the cooling fan 200 is controlled to start after a delay after the cleaning equipment 1 operates in the target working mode;
[0094] When the target working mode is determined to be the second preset working mode, the cooling fan 200 is controlled to start immediately after the cleaning equipment 1 operates the target working mode;
[0095] The heat dissipation requirement of the battery pack 120 in the first preset working mode is less than that in the second preset working mode.
[0096] Furthermore, the processor can invoke the control program of cleaning device 1 stored in memory and perform the following operations:
[0097] The first preset working mode is steam mode. When the target working mode is determined to be the first preset working mode, the step of controlling the cooling fan 200 to start after a delay after the cleaning equipment 1 operates in the target working mode includes:
[0098] When the target working mode is determined to be steam mode, the cooling fan 200 is controlled to start and continue to run after the cleaning equipment 1 has been running in steam mode for a first set time.
[0099] Furthermore, the processor can invoke the control program of cleaning device 1 stored in memory and perform the following operations:
[0100] The second preset working mode is the charging mode. When the target working mode is determined to be the second preset working mode, the step of controlling the cooling fan 200 to start immediately after the cleaning device 1 operates in the target working mode includes:
[0101] When the target working mode is determined to be the charging mode, the cooling fan 200 is started immediately after the cleaning equipment 1 operates in the charging mode, and continues to run until the second set time period before stopping.
[0102] In addition, please see Figure 8 This application also provides a control method for the cleaning device 1 as described above, specifically including the following steps:
[0103] Step S100: Obtain the target operating mode of cleaning equipment 1;
[0104] In this embodiment, when a user inputs a work command via, for example, an input component, the work command is associated with the target work mode desired by the user. The input component can be, for example, a physical or virtual button on the control panel of the cleaning device 1, which the user manually triggers; or it can be a voice or image recognition component in the cleaning device 1, where the user issues a pre-defined voice command or a pre-defined gesture or image command.
[0105] Step S200: When the target working mode is determined to be the first preset working mode, the cooling fan 200 is controlled to start after a delay after the cleaning equipment 1 operates the target working mode;
[0106] Step S300: When the target working mode is determined to be the second preset working mode, the cooling fan 200 is controlled to start immediately after the cleaning equipment 1 operates the target working mode;
[0107] The heat dissipation requirement of the battery pack 120 in the first preset working mode is less than that in the second preset working mode.
[0108] In this embodiment, the control system of the cleaning device 1 pre-classifies the various operating modes of the cleaning device 1. For example, based on the heat dissipation requirements of the battery pack 120 during operation, all operating modes with heat dissipation requirements not lower than a set threshold are classified as preset operating modes; the remaining operating modes with heat dissipation requirements lower than the set threshold are classified as other operating modes. Since the temperature rise of the battery pack 120 is not too high under other operating modes, the cooling fan 200 in the body 10 does not need to operate. Each operating mode in the preset operating modes has different specific heat dissipation requirements, and a required heat dissipation scheme can be pre-matched to it as a preset heat dissipation scheme. In this way, the cooling fan 200 can be linked to enable at least some different preset heat dissipation schemes corresponding to different preset operating modes, which can effectively dissipate heat from the battery pack 120 under each preset operating mode and also help prevent energy waste, achieving energy saving and consumption reduction. The preset heat dissipation scheme includes the start-up time, running time, operating parameters (which can adjust the flow rate, direction, and flow rate of the cooling airflow in the cooling duct 130), and shutdown time of the cooling fan 200.
[0109] When the preset operating mode includes the first preset operating mode where the heat dissipation requirement of the battery pack 120 is relatively low, it is understood that when the target operating mode belongs to the first preset operating mode, heat dissipation of the battery pack 120 is required, but the requirements for heat dissipation time and intensity are not high. In this case, the cooling fan 200 can be started after a delay after the cleaning device 1 operates the target operating mode, so that the battery pack 120 generates a certain amount of heat within a safe temperature range before heat dissipation, avoiding ineffective heat dissipation due to premature start of the cooling fan 200.
[0110] Specifically, in one embodiment, step S200 includes:
[0111] Step S210: When the target working mode is determined to be steam mode, the cooling fan 200 is controlled to start and continue to run after the cleaning equipment 1 has been running in steam mode for a first set time.
[0112] In this embodiment, when the cleaning device 1 is a floor scrubber and the target operating mode is steam mode, the cooling fan 200, which is set up as an exhaust fan, can be started after running in steam mode for, for example, 3 minutes. The cooling fan 200 continues to run, and even if the steam mode is switched to normal mode after 3 minutes, since normal mode is a different operating mode, it will not affect the continued operation of the cooling fan 200.
[0113] When the preset operating mode includes the second preset operating mode, which has a higher heat dissipation requirement for the battery pack 120, the battery pack 120 experiences a rapid temperature rise and reaches a high temperature, requiring more timely and intensive heat dissipation. In this case, the cooling fan 200 can be started immediately when the cleaning equipment 1 is running the target operating mode.
[0114] Specifically, step S300 includes:
[0115] Step S310: When the target working mode is determined to be the charging mode, the cooling fan 200 is controlled to start immediately after the cleaning device 1 runs the charging mode, and continues to run until the second set time period before stopping.
[0116] When the cleaning device 1 is a floor scrubber and the target operating mode is charging mode, the cooling fan 200 can be started immediately when the floor scrubber is switched to charging mode, i.e., placed on the charging base, and will stop after running for, for example, 40 minutes. At this time, the charging mode is independent of the floor scrubber's drying mode, self-cleaning mode, etc., and is only related to the charging mode. The 40 minutes mentioned is merely one example and relates to the duration of a complete charge. If the required charging time is less than 40 minutes when the machine body 10 is switched to charging mode, the cooling fan 200 can be stopped after the machine body 10 is fully charged or after the set conditions are met.
[0117] In this application, the operation of the cooling fan 200 is associated with the operating mode of the cleaning device 1 body 10. There is no need to install sensors at the cooling fan 200 or the battery pack 120. Instead, the operation of the cooling fan 200 is associated with the sensing results of the sensors. This can effectively avoid abnormal control of the operation of the cooling fan 200 when the sensors malfunction, and has higher reliability.
[0118] It should be noted that the cleaning system proposed in this application includes a steam generator. The steam generator can be installed on the cleaning equipment or base station and can supply steam to the cleaning components of the cleaning equipment during operation to improve the self-cleaning efficiency of the cleaning components. Alternatively, the steam generator can be directly installed on the cleaning equipment and supply steam to the cleaning components during normal operation of the cleaning equipment to improve the cleaning effect. The steam generator is activated in the above cleaning mode, and those skilled in the art will understand the concept of the above steam mode.
[0119] Furthermore, in charging mode, the base station supplies power to the battery pack of the cleaning equipment, and those skilled in the art will understand the concept of the aforementioned charging mode.
[0120] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
