Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly to a floor brush assembly and cleaning equipment. Background Technology

[0002] Cleaning equipment such as vacuum cleaners and floor scrubbers are usually equipped with roller brushes, which are driven by motors to rotate at high speed, thereby sweeping up and rolling away dust and debris from the floor.

[0003] In actual cleaning processes, especially when dealing with long hair, pet hair, or tufts, these fibrous debris easily become entangled on the roller brush. As usage time increases, the entanglement accumulates, leading to increased roller brush resistance, higher energy consumption, and a significant decrease in cleaning effectiveness. Currently, the main method for dealing with roller brush entanglement still relies on manual removal by the user. However, manual cleaning requires interrupting the cleaning process, disassembling the brush, and using tools such as scissors to remove the entanglement piece by piece. This process is cumbersome, time-consuming, and laborious, and can easily damage the roller brush structure, severely impacting the user experience.

[0004] Therefore, there is an urgent need for a cleaning device that can automatically and in real time clean up the debris entangled on the roller brush during equipment operation. Utility Model Content

[0005] In view of the above problems, this application provides a floor brush assembly and cleaning equipment that can automatically and in real time clean up the tangled material on the roller brush during the cleaning process, effectively prevent tangling, thereby extending the service life of the equipment, improving the cleaning effect, and enhancing the operational reliability and stability of the equipment.

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

[0007] The first aspect of this application provides a floor brush assembly, including:

[0008] Ground brush body;

[0009] A roller brush, which is rotatably mounted on the floor brush body and is rotatable about its own axis;

[0010] A combing component is movably mounted on the brush body, the combing component having teeth that are in direct contact with the surface of the roller brush;

[0011] The driving mechanism drives the combing component to perform reciprocating periodic linear motion along the axial direction of the brush when the brush rotates around its own axis.

[0012] In the floor brush assembly provided in this application embodiment, a driving mechanism and a combing component are provided. The combing component has teeth that directly contact the surface of the roller brush. When the roller brush rotates around its own axis, the driving mechanism drives the combing component to make reciprocating periodic linear motion along the axial direction of the roller brush, so that the teeth dynamically and thoroughly scrape and comb along the circumference and axial direction of the roller brush. This effectively prevents the accumulation of hair and fibers on the surface of the roller brush, reduces the running resistance of the roller brush, thereby saving energy and reducing the equipment failure rate. It not only improves the cleaning effect of the roller brush and the stability of the equipment tooling, but also further enhances the reliability of the equipment and the user experience.

[0013] In some alternative implementations, the drive mechanism includes:

[0014] A driving member is disposed at one end of the roller brush and rotates synchronously with the roller brush. The driving member is configured to apply a driving force along the axial direction of the roller brush to the combing member during rotation, so as to drive the combing member to move along the axial direction of the roller brush toward a side away from the driving member.

[0015] A reset member is configured to provide a reset force to the combing member in the opposite direction to the driving force provided by the drive member, so as to drive the combing member to move along the brush axis toward the side closer to the drive member;

[0016] When the roller brush rotates, the driving force provided by the driving member and the reset force provided by the reset member act alternately on the combing member to jointly drive the combing member to perform the reciprocating periodic linear motion along the axial direction of the roller brush.

[0017] In this way, the rotational power of the roller brush is converted into mechanical power to drive the combing component to move along the axial direction of the roller brush by the driving component, eliminating the need for an additional drive motor and significantly reducing the energy consumption of the whole machine. In addition, the alternating action of the reset component and the driving component provides a continuous, regular and alternating driving force for the combing component, ensuring that the combing component achieves a smooth, reliable and periodically constant reciprocating motion along the axial direction of the roller brush, thereby effectively enhancing the continuous cleaning capability of the material wrapped around the roller brush surface.

[0018] In some alternative embodiments, the driving member is a driving cam fixed to one end of the roller brush. The driving cam has a driving surface. When the driving cam rotates with the roller brush, the driving surface periodically pushes against the combing member, so that the combing member generates a displacement along the axial direction of the roller brush toward the direction away from the driving member.

[0019] In this way, the rotational power of the roller brush is converted into mechanical power to drive the combing parts to move along the axial direction of the roller brush by driving the cam. The structure is simple and the cost is low.

[0020] In some alternative embodiments, the drive cam is annular and sleeved on one end of the roller brush, the outer peripheral wall of the drive cam has at least one first protrusion, and the drive surface is formed on the side of the first protrusion facing the combing member.

[0021] In this way, the drive cam is directly fixed to the end of the roller brush by a sleeve, without the need for other parts for fixation, which reduces the number of parts and thus reduces equipment costs. In addition, by utilizing the interaction between the drive surface formed by the first protrusion on the outer peripheral wall of the drive cam and the combing component, the rotational power of the roller brush is efficiently and reliably converted into mechanical power to drive the axial movement of the combing component. The structure is simple and compact, without the need for complex transmission mechanisms or additional power sources, which effectively reduces manufacturing and assembly costs.

[0022] In some alternative implementations, the driving surface is a curved surface or an inclined surface.

[0023] This allows for a smoother and more seamless contact and force transmission between the drive surface and the combing components, effectively reducing impact and vibration during movement, thereby reducing noise caused by the movement.

[0024] In some optional embodiments, the reset element is a reset cam, which is fixed to one end of the roller brush away from the drive element. The reset cam has a reset surface, and the reset surface and the drive surface are offset in the circumferential direction of the roller brush. When the reset cam rotates with the roller brush, the reset surface periodically pushes against the combing element, so that the combing element moves toward the drive element along the axial direction of the roller brush.

[0025] In this way, by setting the reset component as a reset cam fixed at the other end of the roller brush, and arranging the reset surface on the reset cam and the drive surface of the drive cam in a circumferentially offset manner, the same rotational motion of the roller brush can be used to push the combing component sequentially and alternately through the drive surface and the reset surface, thus forming a complete, continuous and self-sustaining reciprocating drive mechanism. This improves the reliability and stability of the equipment under different working conditions over a long period of time, while further simplifying the structure and reducing production and maintenance costs.

[0026] In some alternative embodiments, the reset cam is annular and sleeved on the end of the brush away from the drive cam, and the outer peripheral wall of the reset cam has at least one second protrusion, and the reset surface is formed on the side of the second protrusion facing the combing member; wherein the reset surface is an inclined surface or a curved surface.

[0027] In this way, the reset cam can be directly fixed to the end of the roller brush by a sleeve, eliminating the need for other fixing parts, reducing the number of parts and lowering equipment costs. By setting a second protrusion on the reset cam, a reset surface is formed on the second protrusion, which works in conjunction with the drive cam to jointly utilize the rotational power of the roller brush to achieve bidirectional drive of the combing component. The inclined or curved reset surface ensures a smooth transition of contact force with the combing component, effectively reducing impact, vibration, and wear, and improving the smoothness and durability of the mechanism's operation. In some optional embodiments, the reset component is an elastic component, which is disposed between the end of the combing component away from the drive component and the brush body. When the drive component releases the driving force applied to the combing component, the elastic component drives the combing component to reset towards the side of the drive component through its own elasticity.

[0028] In this way, the elastic component can quickly and automatically reset through its own elastic drive to the combing component, with sensitive response and reliable operation; at the same time, the elastic component has a simple structure, low cost, and is easy to assemble and replace, effectively improving the overall economy and maintainability of the drive mechanism.

[0029] In some optional embodiments, the floor brush assembly further includes two limiting blocks, which are disposed opposite to each other at both ends of the floor brush body and together define an installation space whose extension direction is consistent with the axial direction of the roller brush. The two ends of the combing member are respectively movably connected to the two limiting blocks so that the combing member can periodically reciprocate along its extension direction within the installation space under the alternating force of the driving member and the resetting member.

[0030] This allows for limiting the movement of the combing components along the brush axis, thereby improving the accuracy of the combing components' position along the brush axis and effectively cleaning up hair and other tangled materials on the brush.

[0031] In some optional embodiments, both ends of the combing member have a first guide structure extending along the axial direction of the roller brush, and the floor brush body and / or the limiting block have a second guide structure at a position corresponding to the first guide structure, wherein the first guide structure and the second guide structure slide in cooperation with each other.

[0032] This effectively improves the accuracy of the combing parts' axial movement path along the roller brush, thereby further enhancing the working stability and reliability of the combing parts.

[0033] A second aspect of this application provides a cleaning device, including the floor brush assembly provided in the first aspect.

[0034] The cleaning equipment provided in this application embodiment has the same beneficial effects as the floor brush assembly described above, and will not be repeated here.

[0054] 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] This application provides a cleaning device, which includes, but is not limited to, floor scrubbers, vacuum cleaners, etc. The cleaning device typically includes a floor brush assembly, which includes a floor brush body, a roller brush, and a motor. The roller brush includes a roller and a cleaning cloth or cleaning brush disposed along the outer peripheral wall of the roller. The roller is rotatably connected to the floor brush body. The power output end of the motor has a drive shaft, which is coaxially connected to the roller to drive the roller to rotate at high speed around its own axis, thereby sweeping up and rolling away dust and debris on the floor through the cleaning cloth or cleaning brush on the outer peripheral wall.

[0056] It should be noted that in the following description in this article, the surface of the roller brush refers to a cleaning cloth or cleaning brush with cleaning ability, and the ability of the roller brush to rotate around its own axis refers to rotation around the axis of the roller.

[0057] In addition, the floor brush body has a suction port near the center, and the floor brush body has a suction chamber and a negative pressure device that provides negative pressure to the suction chamber. In this way, when the cleaning equipment is working, the dust and debris swept or rolled up by the roller brush can be sucked into the suction chamber through the suction port.

[0058] However, in actual cleaning processes, especially when dealing with long hair, pet hair, or tufts, these fibrous debris easily become entangled on the roller brush. As usage time increases, the entanglement accumulates, leading not only to increased roller brush resistance and energy consumption but also a significant decrease in cleaning effectiveness. Currently, the main method for dealing with roller brush entanglement still relies on manual removal by the user. However, manual cleaning requires interrupting the cleaning process, disassembling the brush, and using tools such as scissors to remove the entanglement piece by piece. This process is cumbersome, time-consuming, and laborious, and can easily damage the roller brush structure, severely impacting the user experience.

[0059] In order to overcome the shortcomings of the prior art, this application provides an improved floor brush assembly and cleaning device, which enables the device to automatically and in real time clean the tangled material on the roller brush during operation, without the need for manual handling by the user, thereby extending the service life of the device, improving the cleaning effect, and enhancing the operational reliability and stability of the device.

[0060] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0061] Please refer to Figures 1 to 3 As shown in the embodiment of this application, the floor brush assembly 10 includes a floor brush body 100, a roller brush 200, a combing member 300, and a drive mechanism 400. The roller brush 200 is rotatably mounted on the floor brush body 100 and can rotate around its own axis. The combing member 300 is movably mounted on the floor brush body 100 and has teeth 310 that directly contact the surface of the roller brush 200. The length direction of the combing member 300 is consistent with the axial direction of the roller brush 200, and both ends of the combing member 300 in the length direction are respectively connected to the floor brush assembly. 10. The combing part 300 has multiple teeth 310 arranged sequentially along its length. Each tooth 310 is in direct contact with the surface of the roller brush 200. That is, the teeth 310 are in direct contact with the cleaning cloth or cleaning brush on the roller brush 200. In this way, when the roller brush 200 rotates around its own axis, the teeth 310 on the combing part can comb and scrape the cleaning cloth or cleaning brush on the roller brush 200 to remove sewage, debris, dust particles, etc. on the roller brush 200, thereby achieving cleaning and combing of the surface of the roller brush 200.

[0062] In addition, when the roller brush 200 rotates around its own axis, the drive mechanism 400 drives the combing component 300 to perform reciprocating periodic linear motion along the axial direction of the roller brush 200. Under the action of the drive mechanism 400 and the roller brush 200 rotating around its own axis, the teeth 310 can dynamically and without dead angles scrape and comb relative to the roller brush 200 along the circumference and axial direction of the roller brush 200, effectively preventing the accumulation of hair and fiber entanglement on the surface of the roller brush 200, reducing the running resistance of the roller brush 200, thereby saving energy and reducing the equipment failure rate. This not only improves the cleaning effect of the roller brush 200 and the stability of the equipment tooling, but also further enhances the reliability of the equipment and the user experience.

[0063] In some embodiments, the drive mechanism 400 includes a drive motor and a transmission mechanism. The output shaft of the drive motor can be connected to the combing member 300 through the transmission mechanism so that the combing member 300 can be driven to perform periodic linear motion along the axial direction of the roller brush 200 by the forward and reverse rotation of the drive motor. The transmission mechanism includes, but is not limited to, gears and racks. The gears are rotatably connected to the drive shaft. The combing member 300 has meshing teeth that match the rack, and the extension direction of the rack is consistent with the axial direction of the roller brush 200.

[0064] In other embodiments, the drive mechanism 400 includes a drive member and a reset member. The drive member is disposed at one end of the roller brush 200 and rotates synchronously with the roller brush 200. The drive member is configured to apply a driving force along the axial direction of the roller brush 200 to the combing member 300 during rotation, so as to drive the combing member 300 to move along the axial direction of the roller brush 200 toward the side away from the drive member. The reset member is configured to provide a reset force to the combing member 300 in the opposite direction to the driving force provided by the drive member, so as to drive the combing member 300 to move along the axial direction of the roller brush 200 toward the side closer to the drive member. When the roller brush 200 rotates, the driving force provided by the drive member and the reset force provided by the reset member act alternately on the combing member 300 to jointly drive the combing member 300 to perform a reciprocating periodic linear motion along the axial direction of the roller brush 200.

[0065] In this way, the rotational power of the roller brush 200 is converted into mechanical power to drive the combing component 300 to move along the axial direction of the roller brush 200 through the driving component, eliminating the need for an additional drive motor and significantly reducing the overall energy consumption of the machine. In addition, the alternating action of the reset component and the driving component provides the combing component 300 with a continuous, regular and alternating driving force, ensuring that the combing component 300 achieves smooth, reliable and periodically constant reciprocating motion along the axial direction of the roller brush 200, thereby effectively enhancing the continuous cleaning capability of the material wrapped around the surface of the roller brush 200.

[0066] To improve the reliability of the combing component 300's axial movement along the brush roller 200, please refer to... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the floor brush assembly 10 also includes two limiting blocks 500. The two limiting blocks 500 are arranged opposite each other at both ends of the floor brush body 100 along the axial direction of the roller brush 200. The two limiting blocks 500 together define an installation space whose extension direction is consistent with the axial direction of the roller brush 200. The two ends of the combing member 300 are respectively movably connected to the two limiting blocks 500, so that the combing member 300 can periodically reciprocate along its extension direction in the installation space under the alternating force of the driving member and the resetting member. In this way, the spacing of the installation space in the axial direction of the roller brush 200 can be precisely controlled, thereby precisely controlling the gap of the combing member 300 moving along the axial direction of the roller brush 200 in the installation space. The movement of the combing member 300 in the axial direction of the roller brush 200 is limited, thereby improving the accuracy of the combing member 300's position in the axial direction of the roller brush 200, and thus effectively cleaning the hair and other tangled objects wrapped on the roller brush 200.

[0067] In some embodiments, both ends of the combing member 300 have a first guide structure 320 extending axially along the roller brush 200, and the brush body 100 and / or the limiting block 500 have a second guide structure 510 at a position corresponding to the first guide structure 320. The first guide structure 320 and the second guide structure 510 slide against each other, thereby effectively improving the accuracy of the combing member 300's axial movement path along the roller brush 200, and further improving the working stability and reliability of the combing member 300. For example, the first guide structure 320 is a guide shaft, and the second guide structure 510 is a guide hole, with the guide shaft passing through the guide hole and moving along it.

[0068] For example, in such Figure 2 In this design, the first guide structure 320 is a guide shaft, the second guide structure 510 is a guide hole, and the brush body 100 has a first guide groove with a top opening at the position corresponding to the guide shaft at both ends of the combing part 300. Two limiting blocks 500 are symmetrically arranged on the brush body 100, and the two limiting blocks 500 have a second guide groove with a bottom opening at the position facing the first guide groove. The first guide groove and the corresponding second guide groove together form a guide hole through which the guide shafts at both ends of the combing part can pass. In this way, both ends of the combing part 300 are limited in the guide hole and can only move back and forth along the axial direction of the guide hole under the action of the drive mechanism 400, thereby ensuring the accuracy of the position of the combing part 300.

[0069] The limiting block 500 and the brush body 100 can be detachably connected by magnetic attraction, threaded connection or other means, which facilitates the disassembly, replacement and maintenance of the combing component 300, thereby improving the user experience.

[0070] Please refer to Figure 2 , Figure 6 and Figure 7 As shown, the driving component is a driving cam 410 fixed to one end of the roller brush 200. The driving cam 410 has a driving surface 411. When the driving cam 410 rotates with the roller brush 200, the driving surface 411 periodically pushes against the combing member 300. For example, the driving surface 411 periodically pushes against the teeth 310 near the end of the combing member 300, so that the combing member 300 generates a displacement along the axial direction of the roller brush 200 toward the drive component. In this way, the rotational power of the roller brush 200 is converted into mechanical power to drive the combing member 300 to move along the axial direction of the roller brush 200 through the driving cam 410. The structure is simple and the cost is low.

[0071] Please continue to refer to Figure 2 , Figure 6 and Figure 7 As shown, the drive cam 410 is annular and sleeved on one end of the roller brush 200. The outer peripheral wall of the drive cam 410 has at least one first protrusion 412, and the drive surface 411 is formed on the side of the first protrusion 412 facing the combing member 300. In this way, the drive cam 410 is directly fixed to the end of the roller brush 200 by sleeve, without the need for other parts for fixation, reducing the number of parts and thus reducing equipment costs. In addition, by utilizing the interaction between the drive surface 411 formed by the first protrusion 412 on the outer peripheral wall of the drive cam 410 and the combing member 300, the rotational power of the roller brush 200 is efficiently and reliably converted into mechanical power to drive the axial movement of the combing member 300. The structure is simple and compact, without the need for complex transmission mechanisms or additional power sources, effectively reducing manufacturing and assembly costs.

[0072] There can be multiple first protrusions 412. When there are multiple first protrusions 412, the multiple first protrusions 412 can be arranged at equal intervals along the circumferential direction along the outer peripheral wall of the drive cam 410. Each first protrusion 412 has a drive surface 411 on the side facing the combing member 300. In this way, the frequency of the combing member 300 reciprocating along the axial direction of the roller brush 200 can be increased, and the cleaning effect of cleaning hair and other tangled objects on the surface of the roller brush 200 can be further improved.

[0073] For example, such as Figure 7 As shown, the driving surface 411 can be a curved surface or an inclined surface, which enables a smoother and more connected contact and force transmission between the driving surface 411 and the combing part 300, effectively reducing the impact and vibration during the movement, thereby reducing the noise caused by the movement.

[0074] In some embodiments, the reset member is a reset cam, which is fixed to the end of the roller brush 200 away from the drive member. The reset cam has a reset surface, and the reset surface and the drive surface 411 are offset in the circumferential direction of the roller brush 200. When the reset cam rotates with the roller brush 200, the reset surface periodically pushes against the combing member 300, so that the combing member 300 moves towards the drive member along the axial direction of the roller brush 200. In this way, by setting the reset member as a reset cam fixed to the other end of the roller brush 200, and arranging the reset surface on the reset cam and the drive surface 411 of the drive cam 410 offset in the circumferential direction, the same rotational motion of the roller brush 200 can be used to push the combing member 300 sequentially and alternately through the drive surface 411 and the reset surface, respectively, to form a complete, continuous and self-sustaining reciprocating drive mechanism. This improves the reliability and stability of the equipment under different working conditions, while further simplifying the structure and reducing production and maintenance costs.

[0075] In some optional embodiments, the reset cam is annular and sleeved on the end of the roller brush 200 opposite to the drive cam 410. The outer peripheral wall of the reset cam has at least one second protrusion, and a reset surface is formed on the side of the second protrusion facing the combing member 300. The reset surface is inclined or curved, so that the reset cam can be directly fixed to the end of the roller brush 200 by sleeve without other fixing parts, reducing the number of parts and lowering equipment costs. By setting the second protrusion on the reset cam, and forming a reset surface on the second protrusion, and working in coordination with the drive cam 410, the rotational power of the roller brush 200 is used to achieve bidirectional drive of the combing member 300. The inclined or curved reset surface ensures a smooth transition of contact force with the combing member 300, effectively reducing impact, vibration and wear, and improving the smoothness and durability of the mechanism operation.

[0076] When the reset member is a reset cam, if the outer peripheral wall of the drive cam 410 has a first protrusion 412, the reset cam also has a second protrusion. The angle between the first protrusion 412 and the second protrusion in the circumferential direction of the roller brush 200 is always 180°. In this way, the combing member 300 can move back and forth uniformly and periodically along the axial direction of the roller brush 200 during the movement of the roller brush 200.

[0077] In other embodiments, please refer to the reference. Figure 2 and Figure 5As shown, the reset component is an elastic component 420. The elastic component 420 is disposed between the end of the combing component 300 away from the driving component and the brush body 100. When the driving component releases the driving force applied to the combing component 300, the elastic component 420 drives the combing component 300 to reset towards the side of the driving component through its own elasticity. In this way, the elastic component 420 can drive the combing component 300 to reset quickly and automatically through its own elasticity, which is responsive and reliable. At the same time, the elastic component 420 has a simple structure, low cost, and is easy to assemble and replace, which effectively improves the overall economy and maintainability of the driving mechanism 400.

[0078] For example, elastic element 420 is a spring, such as Figure 2 and Figure 5 As shown, the spring can be sleeved on the guide shaft at the end of the combing member 300 and pass through the corresponding guide hole to abut against the side wall of the brush body 100. In this way, when the combing member 300 moves along the axial direction of the roller brush 200 toward the end away from the drive cam 410 under the pushing action of the drive surface 411 of the drive cam 410, the spring is in a compressed state. When the drive surface 411 separates from the teeth 310 near the end of the combing member 300, that is, when the drive surface 411 no longer applies driving force to the combing member 300, the spring drives the combing member 300 to move in the opposite direction (that is, toward the side closer to the drive cam 410) by its own elastic force, thereby realizing the reciprocating motion of the combing member 300 in the axial direction of the roller brush 200.

[0079] Specifically, such as Figure 6 and Figure 7 As shown, when the driving surface 411 of the driving cam 410 rotates to contact the teeth 310 at the end of the combing member 300, the brush 200 rotates around its own axis (as shown). Figure 6 When the brush rotates upwards, the driving surface 411 applies a pushing force to the teeth 310, causing the combing member 300 to move along the axial direction of the brush 200 toward the side opposite to the driving cam 410 (e.g., when rotating upwards). Figure 6 The brush moves from center to left. At this time, the spring located between the combing component 300 and the side wall of the brush body 100 is in a compressed state. As the roller brush 200 continues to rotate, the driving surface 411 and the teeth 310 separate from each other (as shown in the image). Figure 8 and Figure 9 As shown in the figure, the drive cam 410 no longer applies a driving force to the combing member 300. At this time, the spring drives the combing member 300 to move in the opposite direction (i.e. towards the side closer to the drive cam 410) through its own elastic force, thereby realizing the reciprocating motion of the combing member 300 in the axial direction of the brush 200.

[0080] In summary, the floor brush assembly provided in this application embodiment includes a drive mechanism and a combing component. The combing component has teeth that directly contact the surface of the roller brush. When the roller brush rotates around its own axis, the drive mechanism drives the combing component to perform reciprocating periodic linear motion along the axial direction of the roller brush. This allows the teeth to dynamically and thoroughly scrape and comb the roller brush along its circumference and axial direction, effectively preventing the accumulation of hair and fibers on the roller brush surface, reducing the operating resistance of the roller brush, thereby saving energy and reducing the equipment failure rate. This not only improves the cleaning effect of the roller brush and the stability of the equipment tooling, but also further enhances the reliability of the equipment and the user experience.

[0081] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes 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.

[0082] 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.

[0083] 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 top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0084] 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.

[0085] 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.
