Description

Technical Field

[0001] This application relates to the field of glass fiber production technology, and more specifically, to a stirring device. Background Technology

[0002] Currently, the preparation and mixing of sizing agents are crucial steps in glass fiber production lines. Sizing agents, as composite additives, are used to enhance the adhesion between precursor fibers while imparting the necessary flexibility, lubricity, and weather resistance to the finished glass fibers. To ensure the uniform distribution of sizing agent components, the commonly used mixing devices in the industry mainly include key components such as a mixing base, drive unit, mixing shaft, and mixing impeller. These mixing devices typically have the drive unit mounted high up, and the rotation of the mixing shaft drives the mixing impeller located at the bottom of the sizing agent tank. The advantages of this design are that it effectively utilizes gravity, ensures motor heat dissipation, simplifies the structure, and facilitates maintenance and operation. Furthermore, to ensure uniform mixing, the mixing shaft is often designed to be long enough to reach deep into the center of the tank, thus achieving thorough mixing even in large-capacity tanks.

[0003] However, with long-term production practice, this traditional agitator design has gradually revealed its shortcomings in preventing oil contamination. Specifically, the drive unit and impeller in the agitator are connected by an agitator shaft, with the upper and lower ends of the shaft tightly fitted to the drive unit and impeller bearings, respectively, to ensure stability and efficiency during transmission. During drive unit operation, high-speed rotation and friction inevitably generate lubricating oil contaminants containing metal particles. These oil contaminants mainly originate at the junction of the agitator shaft and drive unit. Under gravity, the oil contaminants slide down the agitator shaft and eventually penetrate the wetting agent, contaminating the fiber. Traditional single-layer oil seals are insufficient to completely prevent oil seepage, especially during long-term continuous operation or when the agitator shaft experiences minor wear. The sealing effect of the oil seal gradually decreases, exacerbating the risk of oil contamination. This situation poses a significant threat to product quality, as even trace amounts of metal impurities can severely affect the performance of glass fibers, such as reducing their strength and flexibility, and even leading to production process control issues and increased scrap rates.

[0010] Furthermore, the oil suction assembly also includes an end cap, which is disposed at the end of the mounting cavity away from the drive unit. The periphery of the end cap extends radially along the stirring shaft to be detachably connected to the end of the housing away from the stop ring, thereby enclosing and forming the mounting cavity.

[0011] Furthermore, the drive unit includes a drive shaft, one end of which is disposed inside the drive unit, and the other end of which extends at least partially out of the drive unit. A stirring shaft is disposed on the drive shaft, and the drive shaft is rotatably disposed about its axis to drive the stirring shaft to rotate.

[0012] Furthermore, the stirring device also includes a base, one end of which is connected to the drive unit, and a stirring shaft is mounted on the other end of the base. The end face of the base away from the drive unit is connected to an oil suction assembly. At least a portion of the base is connected to a storage device corresponding to the stirring device, and the storage device is used to store the wetting agent to be stirred.

[0013] Furthermore, the stirring device is equipped with multiple oil suction components, each of which is arranged sequentially on the stirring shaft along the axial direction of the drive shaft, and a sealing ring is provided between two adjacent oil suction components.

[0014] Furthermore, the oil-absorbing assembly includes a housing, which includes a first fastening portion and a second fastening portion symmetrically arranged along the axial direction. The first fastening portion and the second fastening portion surround and form an oil-absorbing cavity. The end face of the first fastening portion for connecting with the second fastening portion is provided with a plurality of first snap-fit ​​members extending along the axial direction of the stirring shaft. The end face of the second fastening portion for connecting with the first fastening portion is provided with a plurality of second snap-fit ​​members extending along the axial direction of the stirring shaft. The first snap-fit ​​members and the second snap-fit ​​members snap-fit ​​together to allow the oil-absorbing assembly to be detachably connected to the stirring shaft. Oil-absorbing members are provided on the arc-shaped surfaces of the first fastening portion and the second fastening portion facing the stirring shaft.

[0015] By applying the technical solution of this application, the drive unit is connected to the stirring shaft through a highly efficient and stable driving method. The stirring impeller is located at the end of the stirring shaft away from the drive unit, thereby achieving effective stirring of the wetting agent raw material. The oil suction component is detachably mounted on the stirring shaft for easy disassembly or maintenance. At least a portion of the oil suction component is arranged around the periphery of the stirring shaft, enabling it to actively capture and absorb oil contaminants generated from the drive unit, effectively preventing oil contaminants from sliding down the stirring shaft into the wetting agent. This application, by providing an oil suction component on the stirring shaft, can effectively absorb oil contaminants generated from the drive unit, effectively preventing oil contaminants from sliding down the stirring shaft into the wetting agent, thus solving the technical problem in the prior art where oil contaminants generated by the drive unit of the stirring device easily slide down the stirring shaft, causing contamination of the wetting agent.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, an embodiment of this application provides a stirring device for stirring a wetting agent, including a drive unit 100, a stirring shaft 200, a stirring impeller 300, and an oil suction assembly 400. The drive unit 100 is drivenly connected to the stirring shaft 200, so that the drive unit 100 drives the stirring shaft 200 to rotate around its axis. The stirring impeller 300 is disposed at the end of the stirring shaft 200 away from the drive unit 100, and at least a portion of the stirring shaft 200 extends into the wetting agent, so that the stirring impeller 300 stirs the wetting agent. The oil suction assembly 400 is detachably disposed on the stirring shaft 200, and at least a portion of the oil suction assembly 400 is arranged around the periphery of the stirring shaft 200 for absorbing oil contamination generated by the drive unit 100. This embodiment effectively solves the problem of oil contamination of the wetting agent by providing a detachable oil suction assembly 400 on the stirring shaft, while ensuring the maintainability of the device. In principle, the oil-absorbing component 400 utilizes the physical adsorption properties of oil. Through oil-absorbing material disposed around the stirring shaft 200, it captures and adsorbs oil generated from the drive unit 100, preventing it from flowing into the wetting agent. In terms of effectiveness, the oil-absorbing component 400 in this embodiment can effectively isolate oil, ensuring the purity of the wetting agent and thus improving the production quality of glass fiber. In other embodiments, a filter screen can be incorporated into the oil-absorbing component 400 to further enhance the oil isolation effect and address the potential risks of oil contamination to product quality.

[0023] By using the stirring device provided in this application embodiment, an oil suction component 400 is provided on the stirring shaft 200, which can effectively absorb the oil stains generated from the drive unit 100 and effectively prevent the oil stains from sliding down the stirring shaft 200 into the wetting agent. This solves the technical problem in the prior art that the oil stains generated by the drive unit 100 of the stirring device can easily slide down the stirring shaft 200 and cause the wetting agent to be contaminated.

[0024] In the above embodiment, the drive unit 100 is connected to the stirring shaft 200 through a highly efficient and stable drive method, ensuring that power is smoothly and continuously transmitted to the stirring shaft 200, enabling it to rotate precisely around the axis. The stirring impeller 300 is located at the end of the stirring shaft 200 away from the drive unit 100, and penetrates into the wetting agent through the rotation of the stirring shaft 200, achieving effective stirring of the wetting agent raw materials. The robust connection between the stirring impeller 300 and the stirring shaft 200 ensures the smooth operation of the stirring process. The oil suction assembly 400 is detachably mounted on the stirring shaft 200, facilitating disassembly or maintenance. At least a portion of the oil suction assembly 400 is arranged around the periphery of the stirring shaft 200, employing oil-absorbing elements or other highly efficient oil-absorbing materials, which can actively capture and adsorb oil stains generated from the drive unit 100, effectively preventing oil stains from sliding down the stirring shaft 200 into the wetting agent.

[0025] Specifically, the oil suction assembly 400 further includes a housing 410 and an oil suction element 401. The housing 410 is arranged around the periphery of the stirring shaft 200 to form an oil suction chamber, and the oil suction element 401 is disposed within the oil suction chamber, fitting against the circumferential surface of the stirring shaft 200. The drive unit 100 is connected to the stirring shaft 200 through a stable and efficient drive method, ensuring that the power of the drive unit 100 can be smoothly and continuously transmitted to the stirring shaft 200. This precise connection design allows the stirring shaft 200 to rotate precisely around its own axis, ensuring the accuracy and stability of the stirring process. The stirring impeller 300 is installed at the end of the stirring shaft 200 away from the drive unit 100, which means that the rotation of the stirring shaft 200 directly drives the stirring impeller 300 to deeply stir the wetting agent, achieving effective mixing of the wetting agent raw materials. At least a portion of the oil suction assembly 400 is spaced apart from the stirring shaft 200, forming an oil suction chamber, in which the oil suction element 401 is disposed. The oil-absorbing component 401 fits tightly against the periphery of the stirring shaft 200, forming an effective barrier that actively captures and adsorbs oil contaminants generated from the drive unit 100. Simultaneously, the oil-absorbing component 401 isolates the oil contaminants within the oil-absorbing chamber, preventing the risk of oil re-entering the wetting agent and protecting product quality.

[0026] In the above embodiments, the design of this oil-absorbing chamber is crucial because it provides a working space for the oil-absorbing component 401 and ensures that oil does not directly contact the wetting agent, thus avoiding contamination. The oil-absorbing component 401, located inside the housing 410, is the core material for oil contamination isolation. It has a highly efficient oil adsorption capacity, capable of capturing oil falling from the drive unit 100 or sliding down the surface of the stirring shaft 200 when the stirring shaft 200 rotates. The oil-absorbing component 401 is set close to the circumferential surface of the stirring shaft 200, increasing the contact area and adsorption efficiency, ensuring effective collection of oil. The stirring shaft 200 not only transmits power from the drive unit 100 to the stirring impeller 300, but also, in this application, serves as the central shaft of the oil-absorbing assembly 400, with the housing 410 forming the oil-absorbing chamber together with it. The rotational motion of the stirring shaft 200 promotes the capture of oil by the oil-absorbing component 401, while the design of the housing 410 prevents the free diffusion of oil on the surface of the stirring shaft 200, enhancing the oil contamination isolation effect.

[0027] In some embodiments, the oil-absorbing component 400 is disposed on one end of the stirring shaft 200 near the drive unit 100. During use, the oil-absorbing component 400 maintains a certain distance from the wetting agent to ensure that oil does not directly contaminate the wetting agent. In other embodiments, the oil-absorbing component 400 may also extend from one end of the stirring shaft 200 along the axial direction of the stirring shaft to the end of the stirring shaft 200 near the stirring impeller 300. The housing 410 and the stirring shaft 200 form a sealed oil-absorbing chamber. During use, the stirring shaft 200 drives at least a portion of the oil-absorbing component 400 to extend into the wetting agent.

[0028] Specifically, a stop ring 440 extending toward the stirring shaft 200 is provided at the end of the housing 410 away from the drive unit 100. The diameter of the inner ring of the stop ring 440 is greater than or equal to the diameter of the stirring shaft 200, so as to stop the movement of the oil suction member 401 along the axial direction of the stirring shaft 200. The housing 410 is arranged around the periphery of the stirring shaft 200, together forming an oil suction chamber. This structure provides a receiving space for the oil suction member 401. The oil suction member 401 is placed inside the oil suction chamber, closely fitting the periphery of the stirring shaft 200, so as to absorb any oil contaminants generated from the drive unit 100 and ensure that these oil contaminants do not enter the wetting agent. At the other end of the housing 410, that is, the end away from the drive unit 100, a stop ring 440 extending toward the stirring shaft 200 is designed. The inner diameter of the stop ring 440 corresponds to the diameter of the stirring shaft 200. Its function is to prevent any potential movement of the oil suction component 401 along the axial direction of the stirring shaft 200, and further prevent oil from sliding vertically. The combination of the stop ring 440 and the housing 410 ensures the stable position of the oil suction component 401. Even when the stirring shaft 200 rotates at high speed or encounters external impact, it can remain in the correct position without displacement, thus ensuring its continuous and effective oil suction capacity. The stirring shaft 200 rotates freely inside the housing 410. The design of the stop ring 440 ensures that the oil suction component 401 will not be carried away or misaligned as the stirring shaft 200 rotates. This design is crucial for protecting the fixed position of the oil suction component 401, as it directly relates to whether oil can be effectively isolated without contaminating the wetting agent.

[0029] Specifically, the oil suction assembly 400 also includes an oil seal 430, which is located on the side of the housing 410 away from the drive unit 100 and is rotatably arranged around the axis of the stirring shaft 200. The oil seal 430, located on the side of the housing 410 away from the drive unit 100 and rotatably arranged around the axis of the stirring shaft 200, primarily enhances the sealing performance of the stirring device. The housing 410 and the oil seal 430 work together to ensure that oil does not easily leak from the gap between the stirring shaft 200 and the housing 410, effectively isolating direct contact between oil and the wetting agent. This tight-contact design ensures that even when the stirring shaft 200 rotates at high speed, the oil seal 430 maintains its sealing function, protecting the oil suction component 401 from additional oil contamination, extending the service life of the oil suction component 401 and the maintenance cycle of the oil suction assembly 400. The use of oil seal 430 not only improves the oil-proof capability of the mixing device but also reduces maintenance frequency. This is because oil seal 430 effectively prevents the spread of oil, reducing the need to replace the oil suction component 401. Furthermore, the material and structure of oil seal 430 can be flexibly selected, such as rubber or silicone, to adapt to the operating requirements of the mixing device under different operating temperatures and pressures, further enhancing the adaptability and reliability of the mixing device and reducing maintenance costs caused by environmental changes.

[0030] Specifically, the oil suction assembly 400 also includes a mounting cavity, in which the oil seal 430 is disposed. At least a portion of the housing 410 is disposed at the end of the stop ring 440 away from the drive unit 100, forming a mounting cavity with the stop ring 440. This enclosure creates a suitable mounting environment for the oil seal 430, ensuring it is securely fixed in a predetermined position, unaffected by the rotational movement of the stirring shaft 200, and maintaining good contact with the stirring shaft 200, effectively preventing oil leakage from the gap between the stirring shaft 200 and the housing 410. The oil seal 430 is precisely installed within the mounting cavity enclosed by the housing 410 and the stop ring 440. This arrangement not only ensures the stability and sealing performance of the oil seal 430 but also provides sufficient space to accommodate the rotational movement of the stirring shaft 200, while preventing external factors from interfering with the oil seal 430, thus improving its reliability and durability. The stop ring 440 not only restricts the axial movement of the oil suction component 401 along the stirring shaft 200 but also, in conjunction with the housing 410, forms the mounting cavity, providing the necessary conditions for the installation of the oil seal 430. This enhanced role of the stop ring 440 makes it one of the key components ensuring the overall sealing performance and oil-proof capability of the oil suction assembly 400.

[0031] In the above embodiments, two ways of forming the mounting cavity are provided. In the first way, the housing 410 and the stop ring 440 together form the mounting cavity. In the second way, the housing 410 itself forms the mounting cavity.

[0032] Specifically, the oil suction assembly 400 also includes an end cap 420, which is located at the end of the mounting cavity away from the drive unit 100. The periphery of the end cap 420 extends radially along the stirring shaft 200 and is detachably connected to the end of the housing 410 away from the stop ring 440 to enclose and form the mounting cavity. The end cap 420 is located at the end of the mounting cavity away from the drive unit 100, and its periphery extends radially along the stirring shaft 200, detachably connected to the end of the housing 410 away from the stop ring 440. This design ensures that the oil seal 430 is adequately protected within the mounting cavity, preventing external impurities or other contaminants from entering, while also facilitating the replacement and maintenance of the oil seal 430. The portion enclosed by the housing 410 and the stop ring 440 forms the basic structure of the mounting cavity, while the addition of the end cap 420 completes the full closure of the mounting cavity. The connection between the end cap 420 and the housing 410 not only enhances the sealing performance of the oil suction assembly 400, but also provides a more closed and controllable environment for the oil seal 430, which helps to maintain the optimal working condition of the oil seal 430 and further improves the oil-proof capability of the stirring device.

[0033] Specifically, the drive unit 100 includes a drive shaft 110, one end of which is disposed within the drive unit 100, and the other end of which at least partially extends out of the drive unit 100. A stirring shaft 200 is mounted on the drive shaft 110, and the drive shaft 110 is rotatably configured around its axis to drive the stirring shaft 200 to rotate. The drive shaft 110 is located inside the drive unit 100, with one end extending into the drive unit 100 and coupled to a power source to receive externally input power; the other end extends at least partially out of the drive unit 100. This design ensures that the drive unit 100 can efficiently and stably transmit power to the stirring shaft 200, while maintaining the structural integrity and operational safety of the drive unit 100. The driving shaft 110, with the stirring shaft 200 mounted on it, allows the drive shaft 110 to convert the received power into the rotational motion of the stirring shaft 200, achieving effective power conversion and transmission. The close fit between the stirring shaft 200 and the drive shaft 110 ensures smooth and consistent power transmission during the stirring process, avoiding power loss and instability, thereby improving stirring efficiency and product quality. The drive shaft 110 is rotatably mounted around its own axis, meaning it can rotate freely within the drive unit 100. This rotational characteristic is the basis for the drive shaft 110 to drive the stirring shaft 200, ensuring that the stirring shaft 200 can perform stirring operations at a predetermined speed and direction.

[0034] Specifically, the stirring device also includes a base 500. One end of the base 500 is connected to the drive unit 100, and a stirring shaft 200 is mounted on the other end of the base 500. The end face of the base 500 away from the drive unit 100 is connected to the oil suction assembly 400. At least a portion of the base 500 is connected to a storage device corresponding to the stirring device, which stores the wetting agent to be stirred. The tight connection between one end of the base 500 and the drive unit 100 not only provides a mounting base for the drive unit 100 but also ensures the stability and safety of the drive unit 100 during operation, preventing equipment displacement due to vibration or external forces, thus avoiding disruption of the stirring operation. The stirring shaft 200 is mounted on the other end of the base 500. This design provides stable support and positioning for the stirring shaft 200, ensuring its straightness and balance during rotation. This is crucial for improving stirring efficiency, reducing mechanical wear, and lowering energy consumption. The end face of the base 500 away from the drive unit 100 is connected to the oil suction assembly 400. This connection not only ensures the fixation of the oil suction assembly 400 but also ensures tight contact between the oil suction assembly 400 and the stirring shaft 200. At least a portion of the base 500 is directly connected to the storage device corresponding to the stirring device. This means that the base 500 is not only a physical support for the stirring device but also directly participates in the storage of the wetting agent. This connection between the storage device and the base 500 ensures stable storage of the wetting agent before stirring and also facilitates material handling after stirring, improving the continuity and efficiency of the production process.

[0035] like Figure 3As shown, specifically, the mixing device is equipped with multiple oil-absorbing components 400, each sequentially arranged along the axial direction of the drive shaft 110. A sealing ring is provided between adjacent oil-absorbing components 400. The mixing device has multiple oil-absorbing components 400, which are arranged sequentially along the axial direction of the mixing shaft 200, forming a multi-stage protection system. This design can more comprehensively capture and isolate oil contaminants generated from the drive unit 100, ensuring that the oil contaminants are intercepted by multiple layers of protection before reaching the wetting agent, thus improving the oil-resistant capability of the mixing device. A sealing ring is provided between each oil-absorbing component 400, i.e., between adjacent oil-absorbing components 400, to enhance their sealing performance. The function of the sealing ring is to prevent oil contaminants from penetrating between the multi-stage oil-absorbing components 400, maintaining the independence and effectiveness of each oil-absorbing component 400, avoiding the accumulation and diffusion of oil contaminants on the mixing shaft 200, thereby ensuring the cleanliness of the internal environment of the mixing device. By sequentially arranging multiple oil-absorbing components 400 along the axial direction on the drive shaft 110 and adding sealing rings between adjacent oil-absorbing components 400, the agitator constructs a more complex and efficient oil contamination isolation system. The multi-level protection, coupled with the tight isolation of the sealing rings, significantly enhances the agitator's ability to prevent oil contamination, reducing the risk of oil contamination of the wetting agent. Simultaneously, the multi-layered protection also provides greater convenience for maintaining and replacing the oil-absorbing components 401, improving the operability and maintenance efficiency of the agitator.

[0036] Specifically, the oil suction assembly 400 includes a housing 410. The housing 410 includes a first fastening portion and a second fastening portion symmetrically arranged along the axial direction. The first fastening portion and the second fastening portion enclose an oil suction cavity. Multiple first snap-fit ​​members extending axially along the stirring shaft 200 are provided on the end face of the first fastening portion for connection with the second fastening portion. Multiple second snap-fit ​​members extending axially along the stirring shaft 200 are provided on the end face of the second fastening portion for connection with the first fastening portion. The first snap-fit ​​members and the second snap-fit ​​members engage to allow the oil suction assembly 400 to be detachably connected to the stirring shaft 200. Oil suction elements 401 are provided on the arc-shaped surfaces of both the first and second fastening portions facing the stirring shaft 200. The housing 410 is composed of the first fastening portion and the second fastening portion symmetrically arranged along the axial direction. These two parts enclose the oil suction cavity, providing working space for the oil suction elements 401. The symmetrical snap-fit ​​design ensures that the housing 410 is stably fixed when surrounding the stirring shaft 200, without interfering with the free rotation of the stirring shaft 200, thus guaranteeing the normal operation of the stirring device. Multiple first and second snap-fit ​​members extending axially along the stirring shaft 200 are respectively provided on the connecting end faces of the first and second snap-fit ​​parts. The mutual cooperation of these snap-fit ​​members forms a detachable connection between the oil suction assembly 400 and the stirring shaft 200, facilitating device maintenance and periodic replacement of the oil suction assembly 401. The snap-fit ​​design simplifies the assembly and disassembly process, improving operability and maintenance efficiency. The oil suction component 401 is disposed on the arc-shaped surface of the first and second fastening parts facing the stirring shaft 200. This means that the oil suction component 401 will cover most of the circumferential surface of the stirring shaft 200, which not only increases the contact area between the oil suction component 401 and the stirring shaft 200 and improves the oil adsorption efficiency, but also ensures the balance of the oil suction component 401 during rotation due to the symmetrical layout, avoiding the influence of uneven weight on the rotational stability of the stirring shaft 200 and the sealing performance of the oil suction component 400.

[0037] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0038] By setting up the oil-absorbing component 400, the oil stains generated by the drive unit 100 during operation can be effectively absorbed and isolated, preventing the oil stains from flowing directly into the impregnating agent, protecting the purity of the impregnating agent, and avoiding adverse effects on the quality of the glass fiber filament.

[0039] Multiple oil-absorbing components 400 are sequentially arranged along the drive shaft 110, forming a multi-level protection system. This design not only increases the layers of oil contamination isolation but also improves the agitator's ability to respond to sudden oil leaks, ensuring the continuity and stability of the production process.

[0040] The detachable connection between the oil suction assembly 400 and the stirring shaft 200, as well as the detachable connection between the first and second fastening parts of the housing 410 via snap-fit ​​components, greatly simplifies the process of maintaining and replacing the oil suction assembly 401, reduces maintenance costs, and improves the operability and service life of the stirring device.

[0041] Sealing rings are installed between multiple oil-absorbing components 400 to further enhance the sealing performance of the stirring device, prevent the spread of oil inside the device, and ensure the stability and durability of the oil absorption effect.

[0042] The stirring shaft 200, driven by the drive shaft 110, can rotate stably with the support of the base 500. This structural design ensures high efficiency in the stirring process and uniformity of the wetting agent, thus improving the overall performance of the stirring device.

[0043] The base 500 not only serves as a stable connection platform between the drive unit 100 and the stirring shaft 200, but also connects directly to the storage device, ensuring the structural stability and operational safety of the stirring device and providing a basic guarantee for the normal operation of the production line.

[0044] The detachable design and multi-level protection system of the mixing device enable it to adapt to different production environments and usage requirements, thus improving its flexibility and applicability.

[0045] By effectively isolating oil contaminants, the quality of the wetting agent is protected, waste during the production process is reduced, and production costs are lowered, reflecting the environmentally friendly and economical design philosophy of the mixing device.

[0046] In summary, the stirring device of this application, through its innovative structural design, achieves multiple objectives such as efficient oil contamination isolation, convenient maintenance, safe operation, and environmental friendliness and economy, providing a more reliable and efficient solution for the preparation of sizing agents in the glass fiber production process.

[0047] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0048] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0049] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0050] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0051] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
