Cleaning equipment and power source

Abstract

This invention provides a cleaning device and a power source. The cleaning device includes a device body and a power source mounted on the device body. The power source includes a housing, a battery pack assembly, and a heat sink. The housing has a first accommodating space and a connection port connecting the first accommodating space to the outside. The first accommodating space is also provided with a reset switch for opening or closing the connection port. The battery pack assembly is disposed in the first accommodating space. When the reset switch closes the connection port, it can prevent the electronic components inside the power source from being affected by the outside. When the reset switch opens the connection port, outside airflow can enter the first accommodating space to cool the battery pack assembly, preventing the battery pack assembly from stopping work or failing to charge. This effectively mitigates the effects of sudden power outages or failure to charge after work, thus effectively reducing the cleaning device's ability to stop suddenly or fail to charge after cleaning.

[0053] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0054] When the inventors were practicing the embodiments of the present invention, they found that traditional cleaning equipment would suddenly stop during use or fail to recharge in time after the work was completed, resulting in a poor user experience.

[0055] Through creative thinking, the inventor discovered that the reason for this is that, in order to make cleaning devices more flexible, reduce their footprint, and facilitate user operation, the size of cleaning devices is getting smaller and smaller. Correspondingly, the size of the power source device on the cleaning device is also getting smaller, resulting in a smaller battery pack capacity. During operation, the battery pack generates a certain amount of heat. The automatic air circulation within the confined space to dissipate heat from the battery pack leads to poor heat dissipation. When the battery pack temperature rises to a certain value, it triggers the over-temperature protection of the battery pack, which forces the battery pack to stop working. It can only resume operation after the battery pack temperature drops below the temperature threshold. This results in the cleaning equipment suddenly stopping during operation or failing to recharge in time after operation.

[0056] To address the aforementioned problems, embodiments of the present invention provide a cleaning device and power source that can effectively cool the battery pack and prevent the over-temperature protection of the battery pack from being triggered.

[0057] To address these issues, the present invention provides the following embodiments to solve or improve at least some of the problems mentioned above. To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0058] In the description of some features in the specification, claims, and accompanying drawings of this invention, the terms "first," "second," etc., are used to distinguish different components, parts, modules, devices, etc., and do not represent a sequential order, nor do they limit "first" and "second" to different types. Furthermore, the embodiments described below are merely some embodiments of this invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0059] It should be noted that the examples in the embodiments of the present invention are only one or a few of all embodiments that can implement the corresponding solutions, and do not constitute an improper limitation on the embodiments of the present invention.

[0060] Figure 1 This is a partial structural diagram of a cleaning device provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of a cleaning device provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the power source device provided in an embodiment of the present invention. Please refer to it. Figures 1-3 .

[0061] In one embodiment of the present invention, a cleaning device is provided, including a device body 200 and a power source device 100 disposed on the device body 200. The power source device 100 is capable of providing power to the device body 200 to enable the device body 200 to perform cleaning operations. For example, the device body 200 has a power-driven execution component for performing cleaning operations on the surface to be cleaned.

[0062] In this embodiment of the invention, the cleaning equipment includes, but is not limited to, handheld cleaning machines, upright cleaning machines, cleaning robots, vacuum cleaners, etc. The cleaning equipment described in the above embodiments and the following embodiments is... Figure 1 and Figure 2 The cleaning equipment shown is used as an example for explanation. It should be noted that, taking the cleaning equipment shown as an example... Figure 1 or Figure 2 The cleaning equipment shown is for illustrative purposes only and does not constitute an improper limitation of the embodiments of the present invention.

[0063] See Figure 1 , Figure 1The image shows a vacuum cleaner, which includes a device body 200. One end of the device body 200 has a handle 260 for the user to hold, and the other end is connected to the outside through a dust collection bin. A power source 100 is mounted on the device body 200 and provides suction power. The device body 200 also has a filter element located between the dust collection bin and the power source 100, which prevents solid debris from entering the power source 100. When the other end of the vacuum cleaner comes into contact with the surface to be cleaned, the suction power provided by the power source 100 draws dust and other solid dirt from the surface into the dust collection bin, thus cleaning the surface.

[0064] See Figure 2 , Figure 2 The image shows a handheld cleaning machine, which includes a device body 200. One end of the device body 200 has a handle 260 for the user to hold, and the other end has a floor brush assembly 270. The device body 200 also includes a power source device 100 and a main control unit. The main control unit controls the power source device 100 and the floor brush assembly 270 to operate in coordination for cleaning. In some feasible embodiments, the device body 200 is also equipped with a clean water tank 280 and a wastewater tank 290. The clean water tank 280 provides cleaning water to the floor brush assembly 270 for cleaning the floor. The wastewater is drawn into the wastewater tank 290 through the floor brush assembly 270. The inlet of the wastewater tank 290 is connected to the floor brush assembly 270, and the outlet of the wastewater tank 290 is connected to the power source device 100, allowing wastewater to be drawn into the wastewater tank 290 by airflow through the floor brush assembly 270.

[0065] In some feasible embodiments of the present invention, the power source device 100 is detachably mounted on the device body 200. When the location of the cleaning device is inconvenient for charging, the power source device 100 can be detached from the device body 200 and moved to a power source for charging. Alternatively, when the cleaning device has not completed its cleaning work, the depleted power source device 100 can be removed from the device body 200 and replaced with a fully charged power source device 100 to save charging time, enabling the cleaning device to continue working to complete the cleaning task and improving the user experience.

[0066] As one possible embodiment, the power source device 100 can be matched with different models of cleaning equipment to perform different cleaning modes. For example, the power source device 100 can be applied to a vacuum cleaner to perform a vacuum cleaner cleaning mode with power and mode adapted to the vacuum cleaner; the power source device 100 can also be applied to a floor scrubber to perform a floor scrubber cleaning mode with power and mode adapted to the floor scrubber. The power source device 100 can be charged when it is applied to a vacuum cleaner, or when it is applied to a floor scrubber, or the power source device 100 can be charged independently. Figure 4This is a cross-sectional structural schematic diagram of a power source device provided in an embodiment of the present invention. Figure 5 This is a partial cross-sectional view of a cleaning device provided in an embodiment of the present invention. Figure 6 for Figure 5 A magnified view of a portion of point A in the middle. Figure 7 This is a schematic diagram of the structure of a battery pack assembly provided in an embodiment of the present invention. The following is in conjunction with... Figures 1 to 7 A detailed description of the power source device 100 is provided.

[0067] Please refer to Figure 4 The power source device 100 includes a housing 110 and a battery pack assembly 120. The housing 110 has a first accommodating space 115, and the battery pack assembly 120 is disposed within the first accommodating space 115. The battery pack assembly 120 can provide electrical energy to power the device 200 when it is installed on the equipment body 200. During operation, the battery pack assembly 120 continuously dissipates heat, causing not only the battery pack assembly 120 itself to heat up, but also the temperature within the first accommodating space 115 to rise continuously. Excessive temperature not only affects the lifespan of the battery pack assembly 120 but may also cause it to explode, posing a danger. To dissipate heat from the battery pack assembly 120, the housing 110 has a communication port 111 that connects the first accommodating space 115 to the outside. Outside air can enter the first accommodating space 115 through the connection port 111. When it flows through the battery pack assembly 120, it can exchange heat with the battery pack assembly 120 to remove the heat from the battery pack assembly 120 and then flow out through the connection port 111, thereby achieving the purpose of cooling the battery pack assembly 120.

[0068] Please refer to Figure 3 and Figure 5 Furthermore, as an achievable embodiment, the power source device 100 has a mounting surface 160 facing the device body 200, and a communication port 111 is located on the mounting surface 160. When the power source device 100 is mounted on the device body 200, there is a gap between the mounting surface 160 and the device body 200. The first accommodating space 115 communicates with the outside through the communication port 111 and the gap, thereby allowing outside air to enter the communication port 111 along the gap or allowing air in the first accommodating space 115 to exit from the communication port 111 and be discharged to the outside along the gap, thereby achieving the purpose of ventilation for the first accommodating space 115.

[0069] To achieve better cooling of battery pack assembly 120, please refer to [link / reference needed]. Figure 4As one feasible embodiment, the power source device 100 further includes a heat sink 123 disposed within the first accommodating space 115. The heat sink 123 drives the airflow within the first accommodating space 115 and passes through the battery pack assembly 120. When the power source device 100 is operating, the heat sink 123 guides and accelerates the external airflow from the connection port 111 into the first accommodating space 115, and guides the airflow within the first accommodating space 115 to fully flow through the battery pack assembly 120 for heat exchange, before finally flowing out through the connection port 111. In other words, the heat sink 123 accelerates the airflow speed between the power source device 100 and the external environment, ensuring that the temperature of the airflow contacted by the battery pack assembly 120 remains relatively close to the external temperature. This effectively cools the battery pack assembly 120, resulting in good heat dissipation of the power source device 100, ensuring the normal operation of the cleaning equipment, and thus guaranteeing a good user experience.

[0070] See Figure 4 , Figure 5In some feasible embodiments of the present invention, the battery pack assembly 120 may include a battery bracket 121 and a battery module 122. The battery bracket 121 is connected to the housing 110 and the battery module 122 respectively. Interconnected heat dissipation ducts are provided between the battery bracket 121, the battery module 122, and the housing 110. The heat sink 123 can drive airflow along the heat dissipation ducts. This promotes airflow within the first accommodating space 115 through the battery module 122, thereby promoting heat dissipation from the battery module 122 and achieving a good cooling effect. Specifically, one possible implementation is that the battery holder 121 has a receiving cavity 1211 inside, and the battery holder 121 has a heat dissipation port 1212 that connects the receiving cavity 1211 to the first receiving space 115. A heat dissipation component 123 is located at the heat dissipation port 1212, and the battery module 122 is located inside the receiving cavity 1211. At least one side wall of the battery holder 121 has an air outlet that connects the receiving cavity 1211 to the first receiving space 115. The heat dissipation component 123 can guide the airflow in the first receiving space 115 through the heat dissipation port 1212 into the receiving cavity 1211 to flow through the battery module 122, and then into the first receiving space 115 through the air outlet of the battery holder, so as to realize the flow of airflow in the battery pack assembly 120. The structure is simple. As another possible embodiment, in order to ensure orderly airflow and thus achieve a cooling effect, the side wall of the battery bracket 121, which forms the receiving cavity 1211, is provided with either a heat dissipation vent 1212 or an air outlet. After the airflow guided by the heat dissipation component 123 enters the receiving cavity 1211, it can only flow back to the first receiving space 115 from the side wall with the air outlet. This ensures that the airflow will undergo a certain amount of heat exchange within the receiving space. There will be no phenomenon where the airflow flows back to the first receiving space 115 directly from the side wall with the heat dissipation component 123 without undergoing heat exchange in the receiving cavity 1211, nor will there be a phenomenon where the airflow that has not yet undergone heat exchange in the first receiving space 115 mixes with the airflow that has already undergone heat exchange. This ensures the order of airflow and thus guarantees a cooling effect.

[0071] Furthermore, as one possible embodiment, the heat dissipation vent 1212 is located on the side of the battery bracket 121 facing the connection port 111, so that the airflow that has not undergone heat exchange from the connection port 111 can enter the receiving cavity 1211 and exchange heat with the battery module 122 within the shortest path by being guided by the heat dissipation component 123, thus avoiding the problem of heat exchange occurring during the flow due to the long path, which would affect the cooling effect.

[0072] As one feasible embodiment, multiple air outlets are spaced apart on the battery bracket 121. After heat exchange with the battery pack assembly 120, the airflow flows out from the multiple air outlets into the first accommodating space 115, reducing airflow resistance and making airflow smoother, which is conducive to the airflow carrying away heat from the battery pack assembly 120. As an optional solution, the heat sink 123 is an exhaust fan. Of course, the heat sink 123 can also be a suction motor, as long as it can guide and accelerate airflow. This embodiment does not make specific limitations.

[0073] As one possible embodiment, the battery module 122 is mounted close to the side wall of the battery bracket 121 with a heat sink 123, so that the airflow guided into the receiving cavity 1211 by the heat sink 123 can fully pass through the battery module 122 and then flow out through the air outlet into the first receiving space 115, thereby enhancing the heat dissipation effect on the battery module 122.

[0074] To better dissipate heat from battery module 122, please combine... Figure 4 , Figure 5 See also Figure 7 In some feasible embodiments of the present invention, the battery module 122 may be implemented in such a way that it includes a plurality of spaced-apart pouch cells 1221, with gaps between adjacent pouch cells 1221. The pouch cells 1221 are arranged along the direction of extension of the outer casing 110, and the spaced sides of the plurality of pouch cells 1221 face the sidewall on which the heat sink 123 is mounted. This arrangement not only allows the airflow guided by the heat sink 123 to pass directly through different gaps when it enters the receiving cavity 1211, thus providing sufficient heat dissipation on both sides of the pouch cells 1221, but also allows space for the pouch cells 1221 to expand when heated.

[0075] The arrangement of multiple pouch cells 1221 can be in parallel, in series with some cells and in parallel with others, in series first and then in parallel, or in parallel first and then in series. As long as there is a gap between two adjacent pouch cells 1221, this embodiment does not impose any specific limitations.

[0076] Furthermore, as an achievable embodiment, the outer casing 110 has a diameter of 92mm, which not only accommodates the installation of a battery module 122 composed of multiple pouch batteries 1221, but also does not affect the heat dissipation of the battery module 122. In addition, this size is conducive to holding the outer casing 110 with one hand, making it easier to assemble and disassemble the power source device 100 on the device body 200.

[0077] Because the battery pack assembly 120 is susceptible to damage from external influences, such as conductive solids or water entering the battery pack assembly 120, it can cause a short circuit. Please refer to... Figure 2 , Figure 3 See Figure 4 In some achievable embodiments of the present invention, when the power source device 100 is installed on the device body 200, the communication port 111 is opened, and when the power source device 100 is removed from the device body 200, the communication port 111 is closed. This not only enables ventilation of the battery pack assembly 120, but also isolates the first accommodating space 115 from the outside when the power source device 100 is removed from the device body 200.

[0078] For details, please refer to Figure 5 and Figure 6 As one possible embodiment, the power source device 100 also includes a reset switch 130 located within the first accommodating space 115. The reset switch 130 is used to open or close the connection port 111. When the power source device 100 requires heat dissipation, the reset switch 130 opens the connection port 111; when the power source device 100 does not require heat dissipation, the reset switch 130 closes the connection port 111. For example, when the power source device 100 is mounted on the device body 200, the reset switch 130 opens the connection port 111 to allow the first accommodating space 115 to communicate with the outside world, facilitating airflow. When the power source device 100 is removed from the device body 200, the reset switch 130 can close the connection port 111 to isolate the battery pack assembly 120 from the outside world.

[0079] Figure 6 This is a schematic diagram of the structure of a device body according to an embodiment of the present invention. Please continue to refer to it. Figure 3 and Figure 4 See Figure 5 and Figure 6 In some feasible embodiments of the present invention, one possible structural configuration of the reset switch 130 is as follows: the reset switch 130 includes a reset element 131 and a switch element 132. The switch element 132 is movably disposed relative to the communication port 111. One end of the reset element 131 is connected to the wall panel structure on the housing 110, and the other end is connected to the switch element 132. The reset element 131 can provide a reset force for the switch element 132. Specifically, the wall panel structure on the housing 110 can be the space wall of the first accommodating space 115, or other wall panel structures capable of providing stable support for the reset element 131. This embodiment does not impose specific limitations on this. Figure 5Taking the vacuum cleaner shown as an example, a stop 230 is provided at the position corresponding to the reset switch 130 on the device body 200. Of course, the same setting is also provided when the cleaning device is a floor scrubber or other cleaning devices with other functions. When the power source device 100 is installed on the device body 200, the stop 230 pushes up the switch 132 through the connecting port 111 to open the connecting port 111. When the power source device 100 is removed from the device body 200, the reset force keeps the reset switch 130 in a closed state of the connecting port 111, thereby ensuring the isolation between the inside of the outer shell 110 and the outside world. This prevents external debris from entering the receiving cavity 1211 and affecting the battery pack assembly 120 when the user forgets to seal the connecting port 111 when the power source device 100 leaves the device body 200. It can be understood that when the power source device 100 is removed from the device body 200 and is not charging, the power source will not be in working state, so the battery pack assembly 120 will not heat up. When the power source device 100 is installed on the equipment body 200, the abutment 230 causes the reset switch 130 to move and open the communication port 111, so that the first accommodating space 115 is connected to the outside, ensuring that the power source device 100 can be effectively cooled by airflow during operation. It should be noted that the first accommodating space 115 will not directly face the outside at this time, thus preventing external debris from entering the first accommodating space 115 and ensuring the normal operation of the battery pack assembly 120. As an optional solution, the reset element 131 can be a spring or a highly elastic rubber pad, as long as the reset element 131 can be compressed and generate a rebound force during compression; this embodiment does not impose specific limitations.

[0080] In some feasible embodiments of the present invention, another feasible structural configuration of the reset switch 130 is as follows: the reset switch 130 includes a reset element 131 and a switch element 132. The reset element 131 is electrically connected to the battery pack assembly 120. When the battery pack assembly 120 is charging or discharging, the reset element 131 provides the switch element 132 with an opening force to open the connection port 111. When the battery pack assembly 120 is not working, the reset element 131 provides the switch element 132 with a reset force to close the connection port 111. Alternatively, the opening force disappears, and the connection port 111 is closed, so that when the cleaning equipment is performing cleaning work or the battery pack assembly 120 is charging, the first accommodating space 115 is connected to the outside. When the battery pack assembly 120 is not charging, external debris is prevented from entering the first accommodating space 115 through the connection port 111. As an illustrative example, the reset element 131 is an electromagnetic element and the switch element 132 is a magnet. When it is necessary to open the connection port 111, the electromagnetic element has electrodes that repel the magnet, thereby driving the magnet to move and open the connection port 111. When it is necessary to close the connection port 111, the electromagnetic element has electrodes that attract the magnet, thereby driving the magnet to open the connection port 111.

[0081] In some feasible embodiments of the present invention, another feasible structural configuration of the reset switch 130 is as follows: the reset switch 130 includes a reset member 131, an opening member, and a switch member 132. Both the reset member 131 and the opening member are electrically connected to the battery pack assembly 120. When the battery pack assembly 120 is charging or discharging, the opening member is connected to the battery pack assembly 120 and provides the switch member 132 with an opening force to open the connection port 111. When the battery pack assembly 120 is not working, the reset member 131 is connected to the battery pack assembly 120 and provides the switch member 132 with a reset force to close the connection port 111. This ensures that when the cleaning equipment is performing cleaning work or the battery pack assembly 120 is charging, the first accommodating space 115 is connected to the outside. When the battery pack assembly 120 is not charging, it prevents external debris from entering the connection port 111. As an illustrative example, both the reset element 131 and the opening element are electromagnetic components, the reset switch 130 is a magnet, the opening element has electrodes that repel the magnet, and the reset element 131 has electrodes that attract the magnet.

[0082] As long as the reset switch 130 can open the connection port 111 when the battery pack assembly 120 is discharging and / or charging, and close the connection port 111 when the battery pack assembly 120 is not working, this embodiment does not impose specific limitations.

[0083] As another possible embodiment, when the power source device 100 is installed on the device body 200, the connection port 111 opens when the device body 200 and / or the power source device 100 starts working, allowing the first accommodating space 115 to communicate with the outside world. This enables air exchange between the first accommodating space 115 and the outside air, reducing the temperature inside the first accommodating space 115. When the device body 200 and / or the power source device 100 stops working, the connection port 111 closes. This prevents external debris from entering the first accommodating space 115 through the gap between the device body 200 and the power source device 100 and damaging the electronic components located within the first accommodating space 115.

[0084] Specifically, when the power source device 100 is installed on the device body 200, the power source device 100 provides electrical energy to the device body 200, and the connection port 111 opens when the device body 200 cleans the surface to be cleaned. Alternatively, when the power source device 100 is installed on the device body 200, and the device body 200 connects to the power source device 100 for charging, the connection port 111 opens. It is understood that the battery pack assembly 120 also generates heat during charging, which will also cause the temperature inside the first accommodating space 115 to rise, thus requiring heat dissipation. Alternatively, when the power source device 100 is removed from the device body 200 for separate charging, the connection port 111 opens, allowing the first accommodating space 115 to connect with the outside, enabling airflow and removing heat from the first accommodating space 115. When the power source device 100 is installed on the device body 200 and the cleaning work on the surface to be cleaned is completed, the user operates to turn off the power on the device body 200, at which point the connection port 111 closes. Alternatively, the connection port 111 may close when the power source device 100, installed on the device body 200, completes charging. Or, the power source device 100 may be charging without being located on the device body 200, and the connection port 111 may close upon completion of charging. It is understood that the electronic components within the power source device 100 do not require heat dissipation at this time, thus isolating the first accommodating space 115 from the outside environment and preventing external influences on the electronic components housed within the first accommodating space 115.

[0085] Furthermore, as a first feasible embodiment, the reset switch 130 is electrically connected to the battery pack assembly 120. When the battery pack assembly 120 is charging or discharging, the reset switch 130 moves to open the connection port 111, thereby enabling the first accommodating space 115 to communicate with the outside when the battery pack assembly 120 is operating. Specifically, as a feasible embodiment, the reset switch 130 includes a switch element 132 and a drive motor. The switch element 132 is movably disposed relative to the connection port 111 and is connected to the output terminal of the drive motor. The drive motor is electrically connected to the battery pack. When the battery pack is charging or discharging, the output terminal of the drive motor rotates simultaneously, thereby driving the switch element 132 to move and open the connection port 111. When the battery pack is fully charged or no longer discharging, the drive motor rotates in the opposite direction, thereby driving the switch element 132 to reset and close the connection port.

[0086] Please combine Figure 4 and Figure 5 ,refer to Figure 6In some feasible embodiments of the present invention, the housing 110 is provided with a limiting portion 113 at the boundary forming the communication port 111. When the reset switch 130 closes the communication port 111, the reset switch 130 abuts against the limiting portion 113, thereby preventing the reset switch 130 from detaching from the housing 110 at the communication port 111 and ensuring a good sealing effect. In another feasible manner, the switch member 132 abuts against the inner wall of the limiting portion 113 when sealing the communication port 111, thereby limiting the movement of the switch member 132 and preventing overtravel of the switch member 132. Exemplarily, the limiting portion 113 may be formed by the housing 110 extending from the boundary forming the communication port 111 toward the center of the communication port 111. The limiting portion 113 may also be a limiting block located on the housing 110 at the communication port 111. Multiple limiting blocks are provided at intervals on the housing at the communication port 111. As long as it can achieve contact with the switch 132 when blocking the connection port 111, this embodiment does not impose specific limitations.

[0087] In some feasible embodiments of the present invention, a sealing element 133 is provided at the contact point between the reset switch 130 and the limiting part 113, which seals against the communication port 111. The reset switch 130 abuts against the limiting part 113 through the sealing element 133, thereby ensuring a good sealing effect between the reset switch 130 and the limiting part 113 when the reset switch 130 blocks the communication port 111, preventing external substances from entering the first accommodating space 115. In one feasible way, a sealing element 133 is provided at the end of the switch member 132 that abuts against the limiting part 113. The sealing element 133 is, but is not limited to, made of rubber or silicone. Under the action of the reset force, the switch member 132, together with the limiting part 113, can provide a certain resistance force to the sealing element 133, causing the sealing element 133 to compress. The compression of the sealing element 133 will generate a rebound force against the compression inside. When the rebound force is equal to the resistance force, the switch member 132 and the sealing element 133 will be in a stable state. Due to the presence of a rebound force, the sealing element 133 can abut against the switch element 132 and the limiting part 113 relatively tightly, thereby ensuring a good seal. The sealing element 133 can be a rubber gasket, which is attached to the end of the switch element 132 that abuts against the limiting part 113 by means of adhesive, or it can be a rubber sleeve, which is fitted around the outer periphery of the switch element 132. As long as the sealing element 133 can be positioned between the switch element 132 and the limiting part 113, this embodiment does not make a specific limitation.

[0088] In some feasible embodiments of the present invention, another possible implementation of the seal 133 is that the limiting part 113 is provided with a seal 133 that seals against the communication port 111 at the abutment point with the reset switch 130. Yet another possible implementation of the seal 133 is that the reset switch 130 is provided with a seal 133 that seals against the inner wall of the communication port 111 at the abutment point with the communication port 111. It should be noted that the above three embodiments of the seal 133 can exist individually, or two of them can exist together, or all three can exist simultaneously. As long as a seal is achieved when the limiting part 113 abuts against the reset switch 130, this embodiment does not impose specific limitations.

[0089] Please combine Figure 4 and Figure 5 ,refer to Figure 6 In some feasible embodiments of the present invention, the first accommodating space 115 further includes a slide 112 for the movement of the switch member 132, the switch member 132 abutting against the inner wall of the slide 112. The slide 112 can restrict the direction of movement of the switch member 132, so that the switch member 132 will not tilt during movement, thereby achieving precise sealing of the communication port 111.

[0090] Please combine Figure 4 and Figure 5 ,refer to Figure 6 In some feasible embodiments of the present invention, one possible structural configuration of the switch member 132 is as follows: the switch member 132 includes a switch body 1321 and a sliding portion 1322. The switch body 1321 is connected to the reset member 131, and the sliding portion 1322 is provided on the portion of the switch body 1321 that abuts against the slide rail 112. This reduces the frictional force of the switch member 132 sliding along the slide rail 112, making the switch member 132 move more flexibly. One feasible configuration is that the sliding portion 1322 can be a ball rotatably embedded in the circumference of the switch body 1321, a roller, a slide rail assembly provided on the slide rail 112 and the switch body 1321, or a lubricating layer; any configuration that reduces friction between the switch body 1321 and the slide rail 112 is acceptable. This embodiment does not impose specific limitations.

[0091] In some achievable embodiments of the present invention, please continue to refer to Figure 4 and Figure 5The power source device 100 also includes a display screen assembly 140 and a power assembly 150. The display screen assembly 140 is disposed on the housing 110 and electrically connected to the battery pack assembly 120. The battery pack assembly 120 provides power to the display screen assembly 140 to enable its operation. The display screen assembly 140 is coupled to the main control unit within the device body 200. The display screen assembly 140 allows the user to view the operating status of the cleaning equipment. In some feasible embodiments, the display screen assembly 140 can also facilitate interaction between the user and the main control unit. The housing 110 also has a second accommodating space 116. The power assembly 150 is disposed within the second accommodating space 116 and electrically connected to the battery pack assembly 120. The battery pack assembly 120 provides power to the power assembly 150, enabling the power assembly 150 to power the device body 200. In some feasible embodiments, the power assembly 150 includes, but is not limited to, a suction motor or a rotary motor.

[0092] In some achievable embodiments of the present invention, please continue to refer to Figure 4 The housing 110 has an internal partition 114 that divides the internal space of the housing 110 into a first accommodating space 115 and a second accommodating space 116. The second accommodating space 116 is located below the first accommodating space 115. The partition 114 has a connecting hole 1141 that connects the second accommodating space 116 and the first accommodating space 115. The power assembly 150 is disposed in the second accommodating space 116 and is electrically connected to the battery pack assembly 120 through the connecting hole 1141. The partition 114 can separate the power assembly 150 from the battery pack assembly 120 to reduce the heat dissipated by the power assembly 150 from spreading into the battery pack assembly 120, prevent the temperature in the first accommodating space 115 from rising too quickly and triggering the over-temperature protection of the battery pack assembly 120, and also prevent the airflow from failing to carry away the heat in the battery pack assembly 120 in time.

[0093] For further information, please continue to refer to [link / reference]. Figure 4 and Figure 5 As one feasible embodiment, the power assembly 150 includes a power component 151 and a shock-absorbing pad 152. The power component 151 is electrically connected to the battery pack assembly 120 through a connecting hole 1141, and the shock-absorbing pad 152 abuts against the wall of the connecting hole 1141 and the power component 151. A portion of the power component 151 that communicates with the battery pack assembly 120, such as a connecting cable, can pass through the connecting hole 1141 and be electrically connected to the battery pack assembly 120. The shock-absorbing pad 152 attenuates the vibration of the power component 151 during operation, preventing vibration from being transmitted to the partition 114, effectively avoiding resonance and reducing noise caused by vibration. Furthermore, it can block airflow from the second accommodating space 116 to the first accommodating space 115, preventing the temperature of the first accommodating space 115 from rising due to the airflow in the second accommodating space 116.

[0094] For further information, please continue to refer to [link / reference]. Figure 4 and Figure 5 As one possible embodiment, the partition 114 is covered with a heat insulation element 117 to prevent the temperature in the second accommodating space 116 from rising into the first accommodating space 115. The heat insulation element 117 can be placed above the partition 114 within the first accommodating space 115, or below the partition 114 within the second accommodating space 116. Of course, the partition 114 can be covered with heat insulation elements 117 on both the top and bottom, as long as heat conduction through the partition 114 is prevented. This embodiment does not impose any specific limitations.

[0095] Figure 8 This is a schematic diagram of the structure of a device body according to an embodiment of the present invention. The following will be combined with... Figure 5 See Figure 8 The connection between the equipment body 200 and the power source device 100 is described in detail.

[0096] In some feasible embodiments of the present invention, the device body 200 has a mounting groove 210, and the power source device 100 is installed in the mounting groove 210. An abutment 230 protruding from the groove wall 220 of the mounting groove 210 is provided at a position corresponding to the communication port 111. When the power source device 100 is installed in the mounting groove 210, the abutment 230 can provide a driving force for the movement of the switch member 132. When the driving force is greater than the reset force of the reset member 131, the switch member 132 can move along the slide rail 112 until the power source device 100 is installed on the device body 200. At this time, the switch member 132 opens the communication port 111. Understandably, when the switch 132 moves along the slide 112 into the first accommodating space 115, it remains in contact with the abutment 230 until the power source device 100 is installed in the equipment body 200, without any deviation. When the power source device 100 is removed from the equipment body 200 but has not detached from it, the switch 132 can still remain in contact with the abutment 230. Thus, under the action of the reset member 131, the switch 132 moves along the slide 112 and closes the communication port 111.

[0097] To facilitate the entry of external air into the first accommodating space 115, one possible approach is to provide an installation gap between the power source device 100 and the equipment body 200 when the power source device 100 is installed in the mounting groove 210, through which the connecting port 111 communicates with the outside. Furthermore, the connecting port 111 is directly opposite the groove wall 220 of the mounting groove 210. The installation gap is relatively small and has a certain degree of curvature, thus preventing external solid waste and water droplets from entering the connecting port 111. This ensures both communication between the connecting port 111 and the outside, and also prevents the battery pack assembly 120 from being affected by external factors.

[0098] To better achieve a detachable connection between the power source device 100 and the equipment body 200, in some feasible embodiments of the present invention, one of the outer shell 110 and the groove wall 220 has a card interface 240, and the other has a latching assembly 250. The latching assembly 250 can engage or disengage with the card interface 240, resulting in a simple structure and convenient operation. Please continue to combine Figure 4 ,refer to Figure 6 One possible implementation is that, in this embodiment, the outer casing 110 has a locking interface 240, and the groove wall 220 is provided with a locking assembly 250. When the power source device 100 is installed in the mounting groove 210, the locking assembly 250 at least partially enters into the locking interface 240, and the locking interface 240 locks the locking assembly 250 to achieve stable installation of the power device. Of course, it is also possible that the outer casing 110 is provided with a locking assembly 250 and the groove wall 220 has a locking interface 240; this embodiment does not make a specific limitation.

[0099] In some feasible embodiments of the present invention, one feasible structure of the latching assembly 250 is that the latching assembly 250 includes a latch 251 and a return member. The latch 251 is connected to the return member and is movably disposed. The return member can provide a return force to the latch 251. When the latch 251 is aligned with the card interface 240, the return member drives the latch 251 to reset so that the latch 251 is latched into the card interface 240, thereby ensuring that the latch 251 will not disengage from the card interface 240 when it is latched into the card interface 240, thus ensuring the stable installation of the power source device 100. Specifically, in this embodiment, one end of the return member is connected to the latch 251, and the other end is connected to the device body 200. The latch 251 is movably mounted on the device body 200. When the power source device 100 is installed in the mounting slot 210, the outer shell 110 at the locking interface 240 abuts against the latch 251, providing a certain driving force to the latch 251. When the driving force is greater than the return force provided by the return member to the latch 251, the latch 251 will move until the power source device 100 is installed in the mounting slot 210. Under the action of the return force, the latch 251 resets to stably install the power source device 100 in the mounting slot 210. The latch 251 may be, but is not limited to, an elastic element, such as a spring, elastic rope, or spring sheet.

[0100] Furthermore, to facilitate the disassembly of the power source device 100, in some feasible embodiments of the present invention, the latch 251 includes a latching portion and a control portion. The latching portion is located at the groove wall 220 for engaging with the latch interface 240. The control portion extends to the outside and can be used to control the latching portion to separate from or connect with the latch interface 240. When a moving force is applied to the control portion, and the moving force is greater than the return force, the end of the latch 251 located on the outside can move to disengage from the latch interface 240, thereby realizing the disassembly of the power source device 100, which is convenient to operate.

[0101] Furthermore, to facilitate the insertion and removal of the latch 251 from the card interface 240, in some feasible embodiments of the present invention, the opening wall of the card interface 240 is provided with a guide structure. This guide structure guides the insertion and removal of the latch 251, making the assembly and disassembly of the power source device 100 more convenient. One feasible method is to refer to... Figure 4 In this embodiment, the outer shell 110 at the card interface 240 is inclined towards the outside of the outer shell 110 to form a guide surface. When the buckle 251 abuts against the guide surface, the guide surface can guide the buckle 251 into the card interface 240 or out of the card interface 240. The structure is simple and easy to manufacture.

[0102] The technical solution adopted in this invention will be described below in conjunction with specific application scenarios to aid understanding.

[0103] Application Scenario 1

[0104] When the user presses the power button or sends a power-on command to the main control unit via the display screen, the handheld cleaner is turned on. At this time, the power source device 100 starts to generate negative pressure. Sewage and other dirt are drawn into the sewage tank 290 through the floor brush assembly 270 along with the airflow. The sewage and airflow are separated in the sewage tank 290. The sewage gathers in the sewage tank 290, and the airflow flows out of the sewage tank 290 through the air outlet and enters the power source device 100. When the cleaning equipment is working, the heat sink 123 is turned on simultaneously. As time goes on, the battery pack assembly 120 in the power source device 100 begins to generate heat. During this process, the heat sink 123 continuously guides the external airflow through the gap between the power source device 100 and the equipment body 200, and enters the first accommodating space 115 through the connecting port 111. The airflow entering the first accommodating space 115 is guided by the heat sink 123 through the heat sink 1212 and enters the first gap or the second gap. After passing through the first gap, it flows into the second gap. After sufficient heat exchange with the soft-pack battery 1221, the airflow carries away the heat of the soft-pack battery 1221. The heated airflow passes through the air outlet and returns to the first accommodating space 115, and then flows out through the connecting port 111 to the gap between the power source device 100 and the equipment body 200, and finally flows to the outside through the gap. This ensures good heat dissipation for the battery pack assembly 120, preventing the battery assembly from overheating and triggering over-temperature protection, avoiding sudden shutdowns during use or failure to charge in time after cleaning, and ensuring that users can successfully complete the cleaning work and charge in time.

[0105] After the user finishes cleaning the surface, they send a shutdown command to the main control unit via the display screen, which turns off the handheld cleaner and moves the handheld cleaner to the charging dock for charging.

[0106] Application Scenario 2

[0107] Based on application scenario one, when the user is cleaning the surface to be cleaned, the battery pack assembly 120 runs out of battery, and the display assembly 140 displays to the user that it should be charged or the power source device 100 should be replaced. At this time, the user applies a moving force to the end of the latch 251 located outside, causing the latch 251 to move to abut against the guide surface. Under the guidance of the guide surface, the latch 251 disengages from the card interface 240, thereby unlocking the power source device 100 from the device body 200. The user removes the power source device 100 that has run out of power. At this time, the reset switch 130 is no longer subjected to pressure. Under the action of the reset force, the switch 132 blocks the connection port 111.

[0108] After the depleted power source device 100 is removed from the device body 200, the user installs the fully charged power source device 100 into the mounting slot 210. During installation, the abutment 230 abuts against the switch 132, driving the switch 132 to slide along the slide rail 112 into the first receiving space 115. Simultaneously, the latch 251 moves towards the slot interface 240 under the action of the guide surface. Once the power source device 100 is in place, the latch 251 aligns with the slot interface 240 and, under the action of the return component, engages into the slot interface 240, preventing the power source device 100 from detaching from the device body 200. At this point, the switch 132 is moved by the abutment 230 to open the communication port 111, allowing the communication port 111 to connect to the outside through the gap between the power source device 100 and the device body 200, ensuring airflow.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
