Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a mite removal device. Background Technology

[0002] A mite removal device is a cleaning device used to remove mites and their excrement from household items such as mattresses, sofas, and carpets.

[0003] In related technologies, mite removal equipment includes a base, a main control circuit board, a roller brush motor, a battery pack, and a UV lamp. The main control circuit board, roller brush motor, battery pack, and UV lamp are all housed inside the base. The base has a charging adapter for plugging in the charging plug to charge the battery pack. The UV lamp can be turned on to sterilize and disinfect bedding and other items during mite removal.

[0004] However, among the related technologies, mite removal equipment suffers from technical problems such as large overall size, heavy weight, unstable center of gravity, and laborious operation. Utility Model Content

[0005] In view of the above problems, this application provides a mite removal device, which aims to reduce the overall size and weight of the device and lower the center of gravity, thereby avoiding the technical problem of laborious operation, improving the structural compactness of the mite removal device, and improving the user experience.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a mite removal device, including: a base, a roller brush motor, and a battery pack assembly; the base has a receiving cavity extending along a first direction, the roller brush motor and the battery pack assembly are located in the receiving cavity and are arranged side by side along the first direction; wherein, the first direction is consistent with the length direction of the base.

[0008] In the mite removal device provided in this application embodiment, by arranging the roller brush motor and battery pack assembly side by side in the accommodating cavity along the first direction, the layout of the roller brush motor and battery pack assembly in the mite removal device is more reasonable, improving the structural compactness of the mite removal device, thereby reducing the overall size and weight of the mite removal device; in addition, the roller brush motor and battery pack assembly are located at the base, which lowers the center of gravity of the mite removal device, improving the stability of the mite removal device during use and reducing the weight of the hand, making operation more effortless, thereby improving the user experience.

[0009] In some embodiments, the battery pack assembly includes a circuit board and two battery packs. The circuit board has a lower surface and an upper surface that are disposed opposite to each other. The two battery packs are symmetrically disposed on the lower surface of the circuit board along the first direction. The upper surface of the circuit board has plug terminals for connecting electronic components.

[0010] This design integrates the battery pack with the circuit board, further improving the structural compactness of the battery pack assembly and reducing the volume occupied by the battery pack assembly in the housing cavity; it also makes the weight distribution of the mite removal device more balanced in the left and right directions, thereby improving the stability of the mite removal device during use.

[0011] In some embodiments, each of the battery packs includes a bracket and two batteries, the bracket having two receiving slots arranged side by side along a second direction, and the two batteries respectively located in the corresponding two receiving slots;

[0012] Two adjacent brackets are connected to each other and to the circuit board. The ends of two batteries in each battery pack are in direct contact with and electrically connected to the ends of two batteries in the adjacent battery pack. The second direction is perpendicular to the first direction and has an inclined angle with the vertical direction.

[0013] This design allows the bracket to protect multiple batteries while also centrally housing them, thereby further improving the structural compactness of the battery pack.

[0014] In some embodiments, the mite removal device further includes an ultraviolet lamp and a micro switch. The micro switch is disposed between the roller brush motor and the battery pack assembly. The ultraviolet lamp is disposed on the side of the battery pack facing the bottom of the base and is electrically connected to the micro switch. The micro switch has a trigger part. The side of the base near the ground has a through hole through which the trigger part can pass. The trigger part can extend into or out of the through hole under the action of external force to control the opening and closing of the ultraviolet lamp.

[0015] This design has two advantages. First, the micro switch is placed in the gap between the roller brush motor and the battery pack assembly, and the UV lamp is placed in the gap between the battery pack and the base. This makes the structural arrangement of the roller brush motor, battery pack assembly, UV lamp, and micro switch in the base more compact, thereby improving the structural compactness of the components in the base cavity and reducing the size of the base. Second, the UV lamp and micro switch are electrically connected for linkage, eliminating the need for manual control of the UV lamp's on / off state, thus improving the automation performance of the mite removal equipment and enhancing the user experience.

[0016] In some embodiments, the circuit board is disposed on the side of the battery pack facing away from the ultraviolet lamp.

[0017] This design makes good use of the gap space on the top and bottom sides of the circuit board, further improves the structural compactness between the components in the base, reduces the size of the base, and thus reduces the overall size of the machine.

[0018] In some embodiments, the receiving cavity further includes a charging adapter head disposed on the side of the battery pack assembly opposite to the roller brush motor, the charging adapter head being electrically connected to the battery, and the charging adapter head having a plug interface communicating with the outside of the base.

[0019] This design makes good use of the gap space between the battery pack and the roller brush motor, improving the structural compactness while also placing the connector on one side of the base, making the connection process between the connector and the external charger interface more convenient and faster.

[0020] In some embodiments, the roller brush motor and the battery pack assembly are centrally disposed within the receiving cavity along the first direction.

[0021] This design lowers the center of gravity of the mite removal device while keeping its center of gravity in the middle, thereby improving the stability of the device during use and enhancing the user experience.

[0022] In some embodiments, the mite removal device further includes a roller brush that is rotatably disposed on the base, and the receiving cavity is located on the rear side of the roller brush.

[0023] This configuration, with the roller brush motor and battery pack assembly placed in the receiving cavity and arranged side by side along the first direction, allows the roller brush, roller brush motor, and battery pack assembly to make reasonable use of the front, back, left, and right spaces of the receiving cavity within the base. This results in a more compact and rational structural layout of the roller brush, roller brush motor, and battery pack assembly within the base, thereby reducing the size of the base and the overall volume of the machine.

[0024] In some embodiments, the mite removal device further includes a plurality of first threaded connectors, and along the first direction, the bracket has at least two spaced-apart first connecting posts, each first connecting post having a first threaded hole, wherein the first connecting post is located between two corresponding receiving slots;

[0025] The circuit board has a first through hole at the position corresponding to each of the first connecting posts, and the first threaded connector passes through the first through hole and is threadedly connected to the corresponding first threaded hole; and / or

[0026] The mite removal device further includes a second threaded connector. One of the two brackets has a second connecting post extending in a first direction. The second connecting post has a second threaded hole. The other of the two brackets has a second through hole. The second threaded connector passes through the second through hole and is threadedly connected to the second threaded hole.

[0027] This configuration ensures that there is no gap between the two battery packs and between the battery packs and the circuit board, thereby improving the structural compactness of the battery pack assembly and reducing its size.

[0028] In some embodiments, the mite removal device further includes at least two third threaded connectors, each of the two brackets having a third through hole at the end facing away from the other, and a third threaded hole at a position corresponding to the third through hole on the base, wherein the third threaded connector passes through the third through hole and is threadedly connected to the third threaded hole.

[0029] And / or,

[0030] At least one of the two brackets has a positioning post on the side facing the circuit board, and the circuit board has a positioning hole, the positioning post and the positioning hole cooperating with each other.

[0031] This design serves two purposes. First, it allows for a seamless connection between the battery pack assembly and the base, improving the structural compactness of the base and battery pack assembly and reducing the size of the base. Second, the positioning posts and holes allow for the pre-setting of the relative positions of the battery pack and circuit board before they are fixed, thereby improving the connection accuracy between the bracket and the circuit board and increasing the speed of subsequent connection between them.

[0032] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the mite removal device provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0063] This application provides a mite removal device, such as... Figure 1 and Figure 2 As shown, the mite removal device 10 includes a base 100 and a body 200, wherein the base 100 has a suction port 102 at its bottom. The length direction of the base 100 is perpendicular to the length direction of the body 200, with a first direction consistent with the length direction of the base 100 and a third direction consistent with the length direction of the body 200.

[0064] like Figure 3 and Figure 4 As shown, the mite removal device 10 also includes an air duct 300 and a dust cup 400. The air duct 300 is disposed in at least one of the base 100 and the main body 200, and its two ends are respectively connected to the suction port 102 and the dust cup 400. The dust cup 400 is disposed on the main body 200. In this way, when the user needs to remove mites and their excrement from mattresses, sofas, carpets and other home furnishings, the user can hold the main body 200 so that the base 100 is in direct contact with the mattresses, sofas, carpets and other home furnishings, so that the negative pressure at the suction port 102 can adsorb the mites and their excrement into the dust cup 400.

[0065] Furthermore, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the mite removal device 10 also includes a roller brush 150, a roller brush motor 110, and a battery pack assembly 120. The roller brush 150 is rotatably mounted on the base 100, the roller brush motor 110 drives the rotation of the roller brush 150, and the battery pack assembly 120 is configured to provide power to the roller brush motor 110. The battery pack assembly 120 allows the mite removal device 10 to be freed from the constraints of a charging cable, and the mite removal area is not limited by the location of the power source.

[0066] Specifically, the base 100 has a receiving cavity 101 extending along a first direction. The roller brush motor 110 and the battery pack assembly 120 are located in the receiving cavity 101 and arranged side by side along the first direction. This reduces the width of the base 100 and improves the compactness of the structure in the base 100, thereby improving the overall structural compactness of the mite removal device 10, reducing the overall size of the device, and concentrating the center of gravity of the mite removal device 10 at the base 100. The lower center of gravity improves the stability of the mite removal device 10 during use while reducing the weight of the device.

[0067] Furthermore, along the first direction, the roller brush motor 110 and the battery pack assembly 120 are centrally located within the receiving cavity 101. This makes the weight of the base 100 more balanced from left to right, lowering the center of gravity of the mite removal device 10 while keeping it centered, thereby improving the stability of the mite removal device 10 during use and enhancing the user experience.

[0068] In addition, such as Figure 7 and Figure 8 As shown, the receiving cavity 101 is located behind the roller brush 150. The roller brush motor 110 and battery pack assembly 120 are combined and arranged side-by-side in the receiving cavity 101 along the first direction. This allows the roller brush 150, roller brush motor 110, and battery pack assembly 120 to make reasonable use of the front-to-back and left-to-right spaces of the receiving cavity 101 within the base 100. This results in a more compact and rational structural layout of the roller brush 150, roller brush motor 110, and battery pack assembly 120 within the base 100, thereby reducing the dimensions of the base 100 in the front-to-back, left-to-right, and up-down directions, and reducing the volume occupied by the mite removal device 10 in the space.

[0069] For example, the two ends of the roller brush 150 are rotatably connected to the base 100, and the rotatable connection methods include, but are not limited to, hole shaft connection, pin shaft connection, rolling bearing connection, etc.

[0070] In some specific embodiments, such as Figure 7As shown, the base 100 also has a suction chamber 103 inside, and a roller brush 150 is located inside the suction chamber 103 and is rolled against the wall of the suction chamber 103. The roller brush 150 is partially exposed on the outside of the base 100 so as to directly contact the household items that need to be removed from mites and dust. During the process of the mite removal device 10 adsorbing mites and their excrement through negative pressure, the roller brush 150 removes the mites and their excrement hidden in the household items through rolling friction relative to the household items, thereby assisting the mite removal device 10 in collecting mites and their excrement and improving the mite removal reliability of the mite removal device 10. Furthermore, the suction chamber 103 is located on the front side of the receiving cavity 101, and the bottom of the base 100 has a suction port 102, which is located on the rear side of the roller brush 150. The two ends of the air duct 300 are connected to the suction chamber 103 and the dust cup 400, respectively. When the mite removal equipment 10 is needed to perform mite removal and dust removal operations, the mites and their excrement in household items such as mattresses, sofas, and carpets are stripped off by the rolling force of the roller brush 150, and under the negative pressure of the suction port 102, they enter the suction chamber 103 of the base 100, and then enter the dust cup 400 through the air duct 300 for centralized collection.

[0071] In the mite removal device 10 provided in this application embodiment, by arranging the roller brush motor 110 and the battery pack assembly 120 side by side in the receiving cavity 101 of the base 100 in the same direction, the layout of the roller brush motor 110 and the battery pack assembly 120 in the mite removal device 10 is more reasonable, which improves the structural compactness of the mite removal device 10, reduces the overall volume of the mite removal device 10, and reduces the setting of connecting parts between the roller brush motor 110 and the battery pack assembly 120 or reduces the length of the connecting parts, thereby reducing the overall weight of the mite removal device 10. In addition, the roller brush motor 110 and the battery pack assembly 120 are arranged at the base 100, which lowers the center of gravity of the mite removal device 10, improves the stability of the mite removal device 10 during use, reduces the hand weight, makes operation more effortless, and thus improves the user experience.

[0072] Furthermore, such as Figure 9 and Figure 10As shown, the battery pack assembly 120 includes a circuit board 121 and two battery packs 122. The circuit board 121 has a lower surface 1211 and an upper surface 1212 that are arranged opposite to each other. The two battery packs 122 are symmetrically arranged on the lower surface 1211 of the circuit board 121 along a first direction, thereby integrating the battery packs 122 with the circuit board 121 into one unit, further improving the structural compactness of the battery pack assembly 120 and reducing the volume occupied by the battery pack assembly 120 in the receiving cavity 101. Moreover, the battery packs 122 are directly connected to the circuit board 121, reducing the number or length of the connecting parts between the circuit board 121 and the battery packs 122, thereby reducing the weight of the battery packs 122, that is, reducing the weight of the mite removal device 10 and improving the user experience. Furthermore, the symmetrical arrangement of the two battery packs 122 on the lower surface 1211 of the circuit board 121 along the first direction makes the weight distribution of the mite removal device 10 more balanced in the left and right directions, thereby improving the stability of the mite removal device 10 during use.

[0073] Additionally, the structure of the circuit board 121 and the two battery packs 122 combined is shown in [the image / description]. Figure 11 and Figure 12 .like Figure 12 As shown, the upper surface 1212 of the circuit board 121 has a plug-in terminal 1215 for connecting electronic components, so as to connect with the battery pack 122 and the roller brush motor 110 by electrical signal, and to control the opening and closing of the battery 1222 and the roller brush motor 110 in the battery pack 122.

[0074] It should be noted that the side of the circuit board 121 facing the ground is the lower surface 1211, and the side of the circuit board 121 facing away from the ground is the upper surface 1212. The circuit board 121 and the battery pack 122 need to be connected by both electrical signals and mechanically to secure them together.

[0075] For example, such as Figure 9 and Figure 10 As shown, each battery pack 122 includes a bracket 1221 and two batteries 1222. The bracket 1221 has two receiving slots 1223 arranged side by side along the second direction. The two batteries 1222 are respectively located in the corresponding two receiving slots 1223, so as to protect the batteries 1222 and centrally arrange multiple batteries 1222, thereby further improving the structural compactness of the battery pack 122.

[0076] It should be noted here that the second direction is perpendicular to the first direction and has an angle of inclination with the vertical direction. Figure 7 , Figure 9 and Figure 10 As shown, the second direction is not horizontal, but is the direction in which the two receiving slots 1223 are arranged.

[0077] In addition, such as Figure 11 and Figure 12 As shown, two adjacent brackets 1221 are interconnected and connected to the circuit board 121, as follows. Figure 9 and Figure 10 As shown, the ends of two batteries 1222 in each battery pack 122 are in direct contact and electrically connected to the ends of two batteries 1222 in the adjacent battery pack 122. This arrangement ensures that the batteries 1222 are connected to each other and the battery pack 122 is connected to the circuit board 121 with minimal distance, thereby improving the overall structural compactness of the battery pack assembly 120 and reducing the weight and volume of the battery pack assembly 120.

[0078] Furthermore, the connection method between the bracket 1221 and the circuit board 121 is as follows:

[0079] The mite removal device 10 also includes multiple first threaded connectors, combined with Figure 10 and Figure 12 As shown, along the first direction, the bracket 1221 has at least two spaced-apart first connecting posts 1224, each with a first threaded hole. The first connecting posts 1224 are located between two corresponding receiving slots 1223. The circuit board 121 has a first through hole 1213 at a position corresponding to each of the first connecting posts 1224. A first threaded connector passes through the first through hole 1213 and is threadedly connected to the corresponding first threaded hole. The arrangement of the first connecting posts 1224, the first through holes 1213, and the first threaded connector allows for a direct, gapless connection between the bracket 1221 and the circuit board 121, thus enabling a direct, gapless connection between the battery pack 122 and the circuit board 121. This further improves the structural compactness of the battery pack assembly 120 and reduces its volume. Furthermore, the threaded connection method is robust and reliable, and installation and disassembly are quick and convenient.

[0080] For example, the first threaded connector is a first bolt that matches the first threaded hole. The number of first connecting posts 1224 on each bracket 1221 is two, three, four, five, etc., then the number of first threaded connectors is the sum of the number of first connecting posts 1224 on the two brackets 1221.

[0081] And continue as Figure 10 and Figure 12As shown, at least one of the two brackets 1221 has a positioning post 1228 on the side facing the circuit board 121, and the circuit board 121 has a positioning hole 1214. The positioning post 1228 and the positioning hole 1214 cooperate with each other to define the position of the two brackets 1221 on the circuit board 121. Before the first threaded connector passes through the first through hole 1213 and is threadedly connected to the corresponding first threaded hole, the bracket 1221 is first engaged with the positioning hole 1214 on the circuit board 121 through the positioning post 1228 to preset the relative position of the two. Then, the first threaded connector passes through the first through hole 1213 and is threadedly connected to the corresponding first threaded hole, thereby improving the connection accuracy between the bracket 1221 and the circuit board 121 and increasing the subsequent connection speed between the first threaded connector and the first threaded hole.

[0082] In the battery pack assembly 120, the connection between the two brackets 1221 is as follows:

[0083] The mite removal device 10 also includes a second threaded connector, such as Figure 9 , Figure 10 and Figure 11 As shown, one of the two brackets 1221 has a second connecting post 1225 extending along a first direction. The second connecting post 1225 has a second threaded hole. The other of the two brackets 1221 has a second through hole 1226. The second threaded connector passes through the second through hole 1226 and is threadedly connected to the second threaded hole, thereby fixing the two brackets 1221 together without gap, reducing the connection distance between the two brackets 1221, improving the structural compactness between the two battery packs 122, and reducing the volume of the battery pack assembly 120.

[0084] For example, the second threaded connector is a second bolt. Second connecting posts 1225 can be provided on the upper and lower sides of one of the two brackets 1221, and second through holes 1226 are provided at corresponding positions on the upper and lower sides of the other bracket. Before the battery pack 122 is connected to the circuit board 121 via the brackets 1221, the two brackets 1221 housing the battery 1222 are first fixedly connected by the second threaded connector and the second threaded hole.

[0085] The connection between the battery pack assembly 120 and the base 100 is as follows:

[0086] In addition, the mite removal device 10 also includes at least two third threaded connectors, combined with Figure 12 , Figure 13 and Figure 14As shown, each of the two brackets 1221 has a third through hole 1227 at the end facing away from the other. A third threaded hole 104 is located on the base 100 at a position corresponding to the third through hole 1227. A third threaded connector passes through the third through hole 1227 and is threadedly connected to the third threaded hole 104. This allows for a direct, gapless connection between the battery pack assembly 120 and the base 100, thereby improving the structural compactness between the base 100 and the battery pack assembly 120 and reducing the volume of the base 100.

[0087] For example, the third threaded connector is a third bolt, and the number of third through holes 1227 is the same as the number of third threaded connectors, which can be two, four, six, etc. Of course, a third connecting post can also be provided on the base 100, and the third threaded connector is threaded through the third through hole 1227 and connected by the third threaded hole 104 by the third connecting post having a third threaded hole 104.

[0088] In some embodiments, return Figure 5 and Figure 6 As shown, the mite removal device 10 also includes an ultraviolet lamp 130 and a micro switch 140. The micro switch 140 is disposed between the roller brush motor 110 and the battery pack assembly 120, utilizing the gap space between the roller brush motor 110 and the battery pack assembly 120 to further improve the structural compactness of the components in the base 100. The ultraviolet lamp 130 is disposed so that the mite removal device 10 can irradiate household items with ultraviolet light during operation, thereby playing a role in sterilization and mite killing. The ultraviolet lamp 130 is disposed on the side of the battery pack 122 facing the bottom of the base 100, utilizing the gap space between the battery pack 122 and the base 100, which also further improves the structural compactness of the components in the base 100.

[0089] Furthermore, the ultraviolet lamp 130 is electrically connected to a micro switch 140. The micro switch 140 has a trigger part 141, and the base 100 has a through hole on the side near the ground through which the trigger part 141 can pass. The trigger part 141 can extend into or out of the through hole under external force to control the opening and closing of the ultraviolet lamp 130. This configuration ensures that when the mite removal device 10 is operating, the trigger part 141 contacts the household items, triggering the micro switch 140 to turn on the ultraviolet lamp 130; after the mite removal device 10 stops operating, the trigger part 141 releases contact with the household items, and the micro switch 140 simultaneously de-triggers, turning off the ultraviolet lamp 130. Therefore, the opening and closing of the ultraviolet lamp 130 no longer requires manual control, thereby improving the automation performance of the mite removal device 10 and enhancing the user experience.

[0090] For example, the number of microswitches 140 can be two, three, four, etc., to improve the sensing sensitivity of the mite removal device 10. This embodiment of the application uses two microswitches 140 as an example for illustration. Along the first direction, the two microswitches 140 are respectively disposed on both sides of the battery pack assembly 120. In addition, the microswitches 140 and the base 100 are elastically connected, and there is an elastic element, such as a spring, between them. When the mite removal device 10 is in a non-working state, the elastic element is in its original state, and the trigger part 141 of the microswitch 140 is in a suspended state. At this time, the ultraviolet lamp 130 is in a closed state. When the mite removal device 10 is in a working state, the trigger part 141 contacts the household items, the trigger part 141 is subjected to force, the elastic element is compressed, and the ultraviolet lamp 130 is in a closed state. Specifically, both ends of the elastic element are fixedly connected to the base 100 and the microswitch 140, respectively. The fixed connection method can be welding, bonding, snap-fit ​​connection, etc.

[0091] In another example, the ultraviolet lamp 130 includes a lamp plate and lamp beads. The lamp beads are fixed on the lamp plate, and the lamp plate is fixed on the base 100. The fixed connection between the lamp beads and the lamp plate can be by bonding, welding, etc., and the fixed connection between the lamp plate and the base 100 can be by bolt and nut connection, bonding, welding, snap-fit ​​connection, etc.

[0092] Furthermore, in combination Figure 5 and Figure 7 As shown, the circuit board 121 is located on the side of the battery pack 122 away from the ultraviolet lamp 130, so as to make reasonable use of the gap space on the upper and lower sides of the circuit board 121, further improve the structural compactness between the components in the base 100, reduce the size of the base 100, and thus reduce the overall volume.

[0093] It should be noted that, for ease of handheld use, the length of the mite removal device 10 is angled to both the horizontal and vertical directions. This ensures that when a user pushes or pulls the mite removal device 10 relative to furniture, the pushing or pulling force applied to it is not solely along the horizontal or vertical direction. Therefore, as... Figure 4 As shown, along the first direction, the cross-sectional shape of the receiving cavity 101 is not rectangular. Therefore, the arrangement of the two receiving slots 1223 in the battery pack 122 bracket 1221 is not horizontal, but inclined at an angle to the horizontal direction. This makes reasonable use of the space in the receiving cavity 101 while reducing the size occupied by the battery pack assembly 120 in the horizontal direction, thereby reducing the width of the base 100. In addition, because the bracket 1221 is inclined, there is a gap space on the side of the battery pack 122 away from the circuit board 121. The ultraviolet lamp 130 is placed here, and this gap space can be used to further improve the structural compactness of the components in the base 100.

[0094] In addition, such as Figure 8 As shown, the receiving cavity 101 also includes a charging adapter head 1011. The charging adapter head 1011 is located on the side of the battery pack assembly 120 away from the roller brush motor 110. The charging adapter head 1011 is electrically connected to the battery 1222 and has a connector that communicates with the outside of the base 100, facilitating connection to an external charger interface for charging the battery 1222. Positioning the charging adapter head 1011 on the side of the battery pack assembly 120 away from the roller brush motor 110 not only makes efficient use of the space between the battery pack assembly 120 and the roller brush motor 110, improving structural compactness, but also makes the connection to an external charger interface more convenient and faster.

[0095] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments" used in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not all embodiments necessarily include that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0096] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0097] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0098] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
