Description

Technical Field

[0001] This utility model relates to the technical field of cleaning tools, specifically to a vacuum cleaner and a vacuuming system. Background Technology

[0002] A vacuuming system consists of a vacuum cleaner and a base station. The vacuum cleaner is used to clean floors or desktops, while the base station removes dirt stored inside the vacuum cleaner and recharges it for future use. However, when the base station charges the vacuum cleaner, the battery often experiences a false charging phenomenon. Specifically, this occurs because the battery temperature rises during charging, and the charging current is limited when the battery temperature is too high. The charger may detect an abnormal charging current and mistakenly interpret it as the battery being fully charged, thus stopping charging—this is the false charging phenomenon. This not only affects the normal use of the vacuum cleaner and reduces the user experience, but frequent false charging can also lead to overcharging or undercharging of the battery, affecting its lifespan. Therefore, it is necessary to provide an effective solution to ensure proper battery charging. Utility Model Content

[0062] This utility model provides a vacuum cleaner 100. For details, please refer to [link / reference needed]. Figure 1 and Figure 3In this embodiment, the vacuum cleaner 100 includes a vacuum body 1, a battery assembly 2, and a cooling channel 3; the battery assembly 2 is disposed on the vacuum body 1; the cooling channel 3 guides airflow through the battery assembly 2; wherein, the vacuum cleaner 100 is adapted to be connected to the base station 200 for sewage discharge, and during the sewage discharge process, the base station 200 forms a suction airflow, at least a portion of which flows through the cooling channel 3.

[0063] In this embodiment, the battery assembly 2 can be electrically connected to the power device (such as the first suction device 5) on the vacuum body 1 to provide the electrical energy required for the operation of the first suction device 5. The battery assembly 2 is prone to generating heat during operation. By providing a cooling channel 3, and the cooling channel 3 can guide airflow through the battery assembly 2, at least a part of the cooling channel 3 can pass through the battery assembly 2, or at least a part of the battery assembly 2 is located in the cooling channel 3. Thus, when airflow is formed in the cooling channel 3, the heat generated by the battery assembly 2 can be carried away by the flow of airflow, thereby achieving heat dissipation of the battery assembly 2 and keeping the battery assembly 2 at a better normal operating temperature. Furthermore, when the vacuum cleaner 100 is connected to the base station 200, a suction airflow can be formed through the base station 200. The suction airflow can be used to suck out the dirt stored in the dust cup of the vacuum cleaner 100 to achieve the sewage discharge of the vacuum cleaner 100. During the sewage discharge process of the vacuum cleaner 100, a flow airflow is formed from the vacuum cleaner 100 toward the base station 200, and the suction airflow flows through the cooling channel 3 in at least part, so that the flow airflow in the cooling channel 3 can quickly remove the temperature of the battery component 2. Without the need for an additional power device, the heat dissipation of the battery component 2 can be better achieved, the service life of the battery component 2 can be better maintained, and the vacuum cleaner 100 can be used better.

[0064] It is understood that the cooling channel 3 can be directly or indirectly connected to the base station 200. The cooling channel 3 can be connected to any point in the sewage discharge path formed between the base station 200 and the vacuum cleaner 100. Thus, when a negative pressure is formed inside the base station 200, airflow can flow from the vacuum cleaner 100 toward the base station 200, so that a flowing airflow can be formed inside the cooling channel 3 to better remove the heat from the battery assembly 2.

[0065] The vacuum cleaner body 1 is generally cylindrical in shape. When the vacuum cleaner 100 is placed on a table or the ground, the axial direction of the vacuum cleaner body 1 extends horizontally. In this embodiment, unless otherwise specified, the description of the orientation of the vacuum cleaner 100 shall be taken into account here. A vacuuming channel is formed within the vacuum cleaner body 1, which is the airflow channel formed when the vacuum cleaner 100 is performing cleaning work. The cooling channel 3 is adapted to be connected to the base station 200 through the vacuuming channel, so that a negative pressure can be formed in the vacuuming channel during sewage discharge, thereby creating airflow in the cooling channel 3. Specifically, the vacuum cleaner 100 may include a dust cup assembly 4, a first suction device 5, and a suction pipe 101. The dust cup assembly 4 includes a dust cup and a filter structure. The dust cup is located at one end of the axial direction of the vacuum cleaner body 1, and preferably, the dust cup is located at the front end of the vacuum cleaner body 1. The suction pipe 101 is in fluid communication with the dust cup. The suction pipe 101 has a suction port facing outward, and preferably, the suction port is facing the front end. When the vacuum cleaner 100 is cleaning, the suction port is adapted to face the surface to be cleaned. The air inlet of the first suction device 5 is connected to the air outlet of the filter structure. The first suction device 5 may be configured as an axial flow fan. The battery assembly 2 is located outside the dust cup. When the vacuum cleaner 100 is cleaning, the first suction device 5 is turned on, creating a negative pressure inside the dust cup. The airflow containing dirt can enter the suction pipe 101 through the suction port and be guided into the dust cup through the suction pipe 101. The airflow is filtered through the filter structure, so that the dirt is retained in the dust cup. The filtered clean airflow flows out of the filter structure and enters the first suction device 5. The airflow from the suction pipe 101 to the first suction device 5 forms a suction channel.

[0066] In one embodiment, the cooling channel 3 is adapted to be connected to the base station 200 via the suction channel. When the vacuum cleaner 100 is placed on the base station 200 for sewage discharge, a negative pressure is formed inside the base station 200, which in turn creates a negative pressure within the entire suction channel, and consequently, a negative pressure is formed within the cooling channel 3. At this time, one end of the cooling channel 3 is adapted to be connected to the outside, and the other end of the cooling channel 3 can be connected to any position within the suction channel, allowing external cooling airflow to enter the cooling channel 3 to remove heat from the battery assembly 2. Specifically, the other end of the cooling channel 3 can be connected to the suction pipe 101, or to the dust cup, or to the connecting channel between the filter structure and the first suction device 5, etc. The connection method is quite flexible and will not be described in detail here. Preferably, the cooling channel 3 can be connected to the connecting path between the dust cup assembly 4 and the air inlet of the first suction device 5, so that the dirt sucked in by the vacuum cleaner 100 can be isolated and retained in the dust cup, and the cooling channel 3 is less likely to be blocked, ensuring a better cooling effect.

[0067] In another embodiment, combined Figure 1 and Figure 3As shown, the cooling channel 3 and the dust extraction channel can be separated. The cooling channel 3 has a first opening 31 suitable for connecting with the base station 200. The cooling channel 3 is directly connected to the base station 200 through the first opening 31. The airflow resistance in the cooling channel 3 is smaller, the airflow efficiency is higher, and the heat dissipation effect is better.

[0068] The battery assembly 2 includes a battery cavity, and a first opening 31 is formed in the battery cavity or on the vacuum cleaner body 1. When the first opening 31 is located on the battery cavity, the battery assembly 2 is closer to the base station 200, the air duct is shorter, and the heat dissipation efficiency is higher. When the first opening 31 is located on the vacuum cleaner body 1, preferably when the first opening 31 and the dust discharge port of the dust cup are on the same side, the first opening 31 can be more conveniently connected to the base station 200 when the vacuum cleaner 100 is placed.

[0069] In one embodiment, a receiving cavity is provided on the vacuum body 1, and the battery assembly 2 can be accommodated in the receiving cavity. At least a portion of the inner cavity of the receiving cavity forms part of a cooling channel 3, so that airflow can flow through the outside of the battery assembly 2 to reduce the temperature of the battery assembly 2.

[0070] In another embodiment, the battery assembly 2 is externally positioned on one side of the vacuum cleaner body 1. The battery assembly 2 is detachably connected to the vacuum cleaner body 1 through the battery cavity. At least part of the inner cavity of the battery cavity forms a cooling channel 3, allowing cooling airflow to flow through the battery assembly 2. The cooling airflow is closer to the high temperature area, thus achieving better heat dissipation. Moreover, it is more convenient to replace and maintain the battery assembly 2.

[0071] It is understandable that one end of the cooling channel 3 is suitable for connection with the base station 200, and the other end of the cooling channel 3 is also set in a flexible position, so that when a negative pressure is formed in the base station 200, an airflow can be formed in the cooling channel 3 to flow towards the base station 200. Preferably, a second opening 32 suitable for connection with the outside is also provided on one side of the battery cavity or the housing cavity. When the vacuum cleaner 100 is suitable for connecting with the base station 200 to discharge sewage, the outside airflow can enter the battery cavity or the housing cavity through the second opening 32 and flow towards the base station 200 through the first opening 31. The low-temperature airflow from the outside can directly enter the battery cavity or the housing cavity. On the one hand, the wind resistance is smaller and the air intake efficiency is higher. On the other hand, the airflow temperature is lower, which is conducive to better reducing the temperature of the battery component 2.

[0072] Of course, the structure of the base station 200 will also differ depending on the arrangement of the dust cup. In one embodiment, the central axis of the dust cup assembly 4 may be approximately parallel to or coincide with the central axis of the suction pipe 101. Preferably, combined with... Figure 1 and Figure 2As shown, the dust cup assembly 4 is coaxially arranged with the vacuum cleaner body 1, and the suction pipe 101 is located on one side of the dust cup assembly 4 and is arranged parallel to the dust cup assembly 4. One axial end of the dust cup is connected to the vacuum cleaner body 1, and the other axial end of the dust cup is provided with a dust discharge port. A cup cover is provided at the dust discharge port. The suction pipe 101 is fluidly connected to the side wall of the dust cup. When the vacuum cleaner 100 is vacuuming, external dirt can enter the dust cup through the suction pipe 101. When the vacuum cleaner 100 is emptying, the dirt in the dust cup can be discharged through the dust discharge port to enter the base station 200. The first opening 31 is formed on the vacuum cleaner body 1 and is located on the outside of the dust cup. The first opening 31 is aligned with the dust discharge port, so that when the vacuum cleaner 100 is placed on the base station 200, the dust discharge port and the first opening 31 can easily connect with the base station 200. Furthermore, the airflow from the dust cup of the vacuum cleaner 100 to the base station 200 is aligned with the airflow from the cooling channel 3 to the base station 200, resulting in higher sludge removal efficiency and cooling efficiency.

[0073] Furthermore, since a handle structure 6 is also provided on one radial side of the vacuum cleaner body 1, and the battery assembly 2 is located on the handle structure 6, when the vacuum cleaner 100 is placed on a horizontal surface, the handle structure 6 is located below the vacuum cleaner body 1. Because the battery assembly 2 is relatively heavy, placing the battery assembly 2 inside the handle structure 6 makes the center of gravity of the vacuum cleaner 100 lower, and it is more stable when placed. Moreover, the dust cup protrudes forward along its axial direction from the battery assembly 2, so as to facilitate the connection between the dust cup's dust outlet and the base station 200. The position of the base station 200 opposite to the first opening 31 can be slightly higher than the position of the base station 200 opposite to the dust cup, so that the cooling channel 3 can be set shorter, which is beneficial to improving the cooling effect.

[0074] In another embodiment, combined Figure 3 and Figure 4 As shown, the central axis of the dust cup assembly 4 is perpendicular to the central axis of the suction pipe 101. When the vacuum cleaner 100 is placed on a horizontal surface, the dust discharge port of the dust cup faces downwards, and the bottom of the dust cup is flush with or slightly higher than the bottom of the battery assembly 2. The suction pipe 101 is fluidly connected to the periphery of the dust cup, and the opening of the suction pipe 101 is arranged radially outwards along the dust cup, allowing the vacuum cleaner 100 to better clean lateral dirt. At this time, the first opening 31 can be directly set on the battery cavity of the battery assembly 2, and the orientation of the first opening 31 is consistent with the orientation of the dust discharge port. The airflow from the dust cup of the vacuum cleaner 100 to the base station 200 is more consistent with the airflow from the self-cooling channel 3 to the base station 200, resulting in higher dirt discharge efficiency and cooling efficiency. Furthermore, by placing the first opening 31 directly on the battery assembly 2, the path of the cooling channel 3 is shorter, and the suction force formed by the base station 200 within the cooling channel 3 is greater, resulting in higher heat dissipation efficiency for the battery assembly 2.

[0075] The vacuum cleaner 100 and the base station 200 will be further described below with reference to a vacuuming system 1000 provided by this utility model. Figure 1 and Figure 3 As shown, the vacuuming system 1000 includes the aforementioned vacuum cleaner 100 and base station 200. The base station 200 is used to connect with the vacuum cleaner 100 and can form a suction airflow. The base station 200 is connected to the cooling channel 3 of the vacuum cleaner 100, so that at least part of the suction airflow can flow through the cooling channel 3. The airflow formed in the cooling channel 3 carries away the heat from the battery assembly 2 of the vacuum cleaner 100, thereby achieving heat dissipation of the battery assembly 2.

[0076] Depending on the different configurations of the cooling channel 3 on the vacuum cleaner 100, the corresponding configuration of the docking channel on the base station 200 also varies. Specifically, the base station 200 has a first channel 7 for docking and communicating with the dust cup assembly 4, and a second channel 9 for docking and communicating with the cooling channel 3. When the vacuum cleaner 100 docks with the base station 200 to discharge waste, negative pressure can be formed in both the first channel 7 and the second channel 9, so that negative pressure can also be formed in both the dust cup assembly 4 and the cooling channel 3, thereby allowing airflow to flow through the cooling channel 3 to carry away the heat from the battery assembly 2 and dissipate heat from the battery assembly 2.

[0077] In one embodiment, when the cooling channel 3 is connected to the dust extraction channel, the first channel 7 and the second channel 9 can at least partially overlap. By connecting the base station 200 to the dust discharge port of the dust cup, a negative pressure can be formed in the cooling channel 3 at the same time as the sewage is discharged, so as to form a heat dissipation airflow, and the structure of the base station 200 is also simpler.

[0078] In another embodiment, the first channel 7 and the second channel 9 are separated, so that the first channel 7 and the second channel 9 can be better controlled independently. When the cooling channel 3 and the dust suction channel are separated, the first channel 7 can be more easily connected to the dust cup, and the second channel 9 can be more easily connected to the cooling channel 3.

[0079] Furthermore, combined Figure 1 and Figure 3As shown, the first channel 7 has a first pair of interfaces 711 that connect with the dust cup assembly 4, and the second channel 9 has a second pair of interfaces 91 that connect with the cooling channel 3. The second pair of interfaces 91 and the first pair of interfaces 711 are located on the same side of the base station 200, and the second pair of interfaces 91 protrudes further outward from the base station 200 than the first pair of interfaces 711. Specifically, the first pair of interfaces 711 connects with the dust outlet of the dust cup, and the second pair of interfaces 91 connects with the first opening 31 of the cooling channel 3. Moreover, when both the first pair of interfaces 711 and the second pair of interfaces 91 are facing upward, the first opening 31 is located on one side of the outer periphery of the dust cup, extending the second pair of interfaces 91 to protrude from the first pair of interfaces 711. The second pair of interfaces 91 is located above the first pair of interfaces 711, so that the second pair of interfaces 91 can better fit the first opening 31 of the cooling channel 3, making the cooling channel 3 shorter and the cooling airflow efficiency higher.

[0080] It is understandable that the power source for the negative pressure generated by the base station 200 may come from the vacuum cleaner 100 or from the base station 200 itself.

[0081] In one embodiment, no power unit is required on the base station 200. The first suction device 5 on the vacuum cleaner 100 is connected to the base station 200, thereby creating negative pressure within the base station 200. Specifically, the air inlet of the first suction device 5 can be connected to both the first channel 7 and the second channel 9, thus creating negative pressure within both channels 7 and 9 to generate exhaust airflow and cooling airflow. This results in a simpler structure and lower cost for the base station 200. Specifically, since the air inlet of the first suction device 5 is also connected to the dust cup assembly 4, a switching structure can also be provided in the vacuum cleaner 100. Through the switching structure, the first suction device 5 can be selectively connected to either the dust cup assembly 4 or the base station 200. When the vacuum cleaner 100 is cleaning, the first suction device 5 is connected to the dust cup assembly 4 and the connection channel between it and the base station 200 is blocked, so that the vacuum cleaner 100 can perform cleaning work better. When the vacuum cleaner 100 is placed on the base station 200 for sewage discharge, the first suction device 5 is connected to the base station 200 and the connection channel between it and the dust cup assembly 4 is blocked, so that the airflow generated by the first suction device 5 can better discharge sewage and cool, making it more powerful and more efficient.

[0082] Furthermore, the second channel 9 can be configured in various ways. One end of the second channel 9 (i.e., the second pair of interfaces 91) is connected to the cooling channel 3, and the other end of the second channel 9 can be connected to the first channel 7 or to the connection path between the first channel 7 and the first suction device 5.

[0083] The first suction device 5 and the base station 200 can be connected through a guide pipe or a pipe structure formed inside the vacuum cleaner 100 and the base station 200. The second channel 9 can be reasonably set to connect with the first suction device 5 according to the specific structure of the base station 200.

[0084] In another embodiment, the base station 200 includes a second suction device 8. The air inlet of the second suction device 8 is connected to both the first channel 7 and the second channel 9. The second suction device 8 creates a negative pressure in the first channel 7 and the second channel 9, thereby creating a negative pressure in the dust cup and the cooling channel 3, so as to realize the discharge of dirt from the dust cup of the vacuum cleaner 100 and the cooling of the battery assembly 2. The second suction device 8 is closer to the first channel 7 and the second channel 9, so the suction efficiency can be higher.

[0085] At this time, one end of the second channel 9 is connected to the cooling channel 3, and the other end of the second channel 9 is connected to the first channel 7 or to the air inlet of the first channel 7 and the second suction device 8. Based on the same principle, the cooling airflow can be better formed in the cooling channel 3 to better dissipate heat from the battery assembly 2.

[0086] The cooling channel 3 has a first opening 31 and a second opening 32. When the second channel 9 is connected to the air inlet of the second suction device 8 or the first suction device 5, one opening of the cooling channel 3 is connected to the second channel 9, and the second opening of the cooling channel 3 is suitable for communication with the outside. Preferably, the second opening 32 can be directly set on the battery cavity or the receiving cavity, so that the air intake at the battery assembly 2 is faster and the airflow temperature flowing through the battery assembly 2 is lower, thereby improving the heat dissipation effect.

[0087] For base station 200, combined with Figure 1 and Figure 3 As shown, the base station 200 includes a base station body, and an air guide cavity 71 and a dust collection cavity 72 disposed within the base station body. A second suction device 8 is connected to the dust collection cavity 72. A first pair of interfaces 711 is disposed at one end of the air guide cavity 71, and the other end of the air guide cavity 71 is connected to the dust collection cavity 72. A dust bag can be disposed in the dust collection cavity 72. When the second suction device 8 is turned on, a negative pressure is formed in both the dust collection cavity 72 and the air guide cavity 71, thereby sucking out the dirt in the dust cup connected to the air guide cavity 71. A second channel 9 is formed on the outside of the air guide cavity 71 and / or the dust collection cavity 72, and extends along the layout direction of the air guide cavity 71 and the dust collection cavity 72. The second channel 9 can be connected to the air guide cavity 71 or the dust collection cavity 72, so that a negative pressure can also be formed in the second channel 9 when the second suction device 8 is working, thereby forming a cooling airflow in the cooling channel 3.

[0088] In another embodiment, when a second suction device 8 is provided on the base station 200, the air inlet of the second suction device 8 can be connected to the first channel 7, and the air outlet of the second suction device 8 can be connected to the second channel 9. When the second suction device 8 is working, it creates a negative pressure to discharge dirt from the dust cup. The airflow discharged by the second suction device 8 is blown into the second channel 9 and enters the cooling channel 3 to dissipate heat from the battery assembly 2. At this time, the temperature of the airflow entering the cooling channel 3 is slightly higher than that in the previous embodiment, but the suction airflow formed by the second suction device 8 can all enter the dust cup, and the exhaust airflow can be reasonably utilized, so there will be no airflow diversion, and the dirt removal effect can be better. In this embodiment, the first opening 31 of the cooling channel 3 forms an air inlet, and the second opening 32 forms an air outlet, so that the hot airflow can be quickly discharged from the battery assembly 2, and the cooling effect is better.

[0089] When the base station 200 is placed on a horizontal surface, the first pair of interfaces 711 and the second pair of interfaces 91 of the base station 200 are located on the same side, with the second pair of interfaces 91 positioned higher than the first pair of interfaces 711 for better alignment. Furthermore, when the dust cup of the vacuum cleaner 100 is coaxially aligned with the vacuum cleaner body 1, both the first pair of interfaces 711 and the second pair of interfaces 91 face upwards. In this case, when the vacuum cleaner 100 is placed on the base station 200, the dust outlet of the vacuum cleaner 100 faces downwards to connect to the first pair of interfaces 711. When the central axis of the dust cup of the vacuum cleaner 100 is perpendicular to the central axis of the vacuum cleaner body 1, both the first pair of interfaces 711 and the second pair of interfaces 91 face one side of the base station 200 to better align with the dust outlet of the dust cup and the first opening 31 of the cooling channel 3.

[0090] Furthermore, the vacuum cleaner 100 also includes a temperature detection element, which is located within the cooling channel 3, and / or within and / or on the outside of the battery assembly 2. By providing one or more temperature detection elements within the cooling channel 3, the temperature of the battery assembly 2 can be better obtained, thereby enabling better control of the operation of the first suction device 5 or the second suction device 8. A controller may also be provided within the vacuum cleaner 100. The controller is electrically connected to the temperature detection element and the first suction device 5 or the second suction device 8. The temperature of the battery assembly 2 can be obtained in real time through the temperature detection element. The controller can compare the real-time detection value obtained by the temperature detection element with a preset normal value. When the temperature of the battery assembly 2 is too high, the real-time detection value will exceed the threshold range of the preset normal value. At this time, the controller will control the first suction device 5 or the second suction device 8 to operate, so that a cooling airflow can be formed within the cooling channel 3, thereby cooling the battery assembly 2. When the real-time detection value obtained by the temperature sensor is within the preset normal threshold range, the controller can control the first suction device 5 or the second leaf extraction device to stop working based on the real-time detection value obtained by the temperature sensor, and repeat this intelligent control process. The temperature sensor enables the vacuum system 1000 to achieve intelligent temperature control, better ensure the charging effect of the battery pack 2, extend the service life of the battery pack 2, and also effectively save energy.

Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
