Abstract

This application relates to a stirring device, including a driving component and a stirring assembly. The stirring assembly includes multiple stirring elements, all of which are driven and connected to the driving component, and each stirring element rotates along its own axis under the drive. At least two of the stirring elements rotate in opposite directions. In this way, the driving component drives multiple stirring elements to rotate around their own axes, thereby inducing the movement of the descaling liquid and chopped carbon fibers. Furthermore, the opposite rotation directions of the stirring elements ensure that the movement directions of the descaling liquid near different stirring elements are not consistent, increasing the system's disorganization level, preventing carbon fiber sedimentation, and promoting carbon fiber decomposition, thus improving the uniformity of carbon fiber dispersion in the descaling liquid.

Description

Technical Field

[0001] This application relates to the field of composite materials technology, and in particular to stirring devices, carbon fiber decomposition systems, and methods for controlling carbon fiber decomposition. Background Technology

[0002] With the development of composite material technology, high-strength, lightweight carbon fiber is increasingly being used in various industries. Carbon fibers shorter than 20mm are called chopped carbon fibers and are used as raw materials for making carbon paper for fuel cells. The production of a snap-finger requires dispersing and loosening the chopped carbon fibers, and the uniformity of this dispersion is crucial for improving the performance of the carbon paper.

[0003] Currently, most delamination methods involve adding a delamination agent to water and stirring it to make the carbon fibers flow in a specific direction. However, during this process, the carbon fibers are prone to entanglement and flocculation, which seriously affects the uniformity of the carbon fibers. Summary of the Invention

[0004] Therefore, it is necessary to provide a stirring device to address the problem that carbon fibers are prone to entanglement and flocculation during the dispersion and decomposition process.

[0005] A stirring device includes a driving member and a stirring assembly. The stirring assembly includes multiple stirring elements, all of which are drivenly connected to the driving member and rotate along their respective axes under the drive of the driving member. Among all the stirring elements, at least two stirring elements rotate in opposite directions.

[0006] The aforementioned stirring device uses a driving component to drive multiple stirring components to rotate around their own axis, thereby driving the descaling liquid and short-cut carbon fibers to move. Furthermore, by using stirring components that rotate in opposite directions, the movement direction of the descaling liquid near different stirring components is not consistent, which increases the degree of system disorder, avoids carbon fiber sedimentation, and promotes carbon fiber decomposition, thereby improving the uniformity of carbon fiber dispersion in the descaling liquid.

[0007] In one embodiment, at least two stirring elements constitute a stirring group, and all stirring groups are spaced apart, wherein in any stirring group, at least two stirring elements rotate in opposite directions.

[0008] In one embodiment, in any mixing group, all the mixing elements are spaced apart, and a flow gap is provided between two adjacent mixing elements.

[0009] In one embodiment, each mixing group includes two mixing elements rotating in opposite directions. All mixing groups are circumferentially spaced on the drive unit and form a central region, with the flow gaps of all mixing groups facing the central region.

[0010] In one embodiment, the agitator includes a rod and blades, with the blades extending helically around the rod along its axial direction.

[0011] In one embodiment, the stirring device further includes a lifting device for controlling the movement of the drive member along the axial direction of the stirring member.

[0012] In one embodiment, the lifting device includes a support base, a support frame, a connector, and a lifter; the support frame is fixedly connected to the support base; the connector is slidably connected to the support frame and fixed to the drive member; the lifter is used to drive the connector to slide on the support frame.

[0013] In one embodiment, there is an operating space between the connector and the support base, the drive member is disposed on the side of the connector facing the operating space, and the stirring assembly is located within the operating space and on the side of the drive member facing the support base.

[0014] A carbon fiber decomposition system includes a storage unit and a stirring device as described above, wherein the storage unit is used to hold the decomposition liquid.

[0015] The aforementioned carbon fiber decomposition system includes a stirring device that uses a driving component to drive multiple stirring components to rotate around their own axis, thereby driving the decomposition liquid and short-cut carbon fibers to move. Furthermore, by using stirring components that rotate in opposite directions, the movement direction of the decomposition liquid near different stirring components is not consistent, which increases the degree of system disorder, avoids carbon fiber sedimentation, and promotes carbon fiber decomposition, thereby improving the uniformity of carbon fiber dispersion in the decomposition liquid.

[0016] A carbon fiber decomposition control method, applied to the aforementioned carbon fiber decomposition system, includes the following steps:

[0017] Control the stirring assembly to move toward one side of the storage container, so that one end of the stirring assembly extends into the dissolution liquid in the storage container;

[0018] The drive unit is controlled to operate, causing the agitators to rotate around their respective axes, and at least two agitators are controlled to rotate in opposite directions.

[0019] The aforementioned carbon fiber decomposition control method is applied to the aforementioned carbon fiber decomposition system. It uses a driving component to drive multiple stirring components to rotate around their own axes, thereby driving the movement of the decomposition liquid and the short-cut carbon fibers. Furthermore, by using stirring components that rotate in opposite directions, the movement direction of the decomposition liquid near different stirring components is not consistent, which increases the degree of system disorder, avoids carbon fiber sedimentation, and promotes carbon fiber decomposition, thereby improving the dispersion uniformity of carbon fibers in the decomposition liquid.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] Current methods for the decomposition of chopped carbon fibers generally involve stirring in an aqueous solution to make the carbon fibers flow in a specific direction. However, this can easily cause the carbon fibers to become entangled and flocculated. Therefore, it is necessary to study a stirring device that is more suitable for the decomposition of chopped carbon fibers.

[0033] See Figure 1 , Figure 1The present application shows a stirring device in some embodiments, including a driving member 2 and a stirring assembly 1. The stirring assembly 1 includes a plurality of stirring members 11, all of which are drivenly connected to the driving member 2, and each stirring member 11 rotates along its respective axis 111 under the drive of the driving member 2; wherein, among all the stirring members 11, at least two stirring members 11 rotate in opposite directions.

[0034] The aforementioned stirring device uses a driving component 2 to drive multiple stirring components 11 to rotate around their own axis 111, thereby driving the desiccant and short-cut carbon fibers to move. Furthermore, by using stirring components 11 that rotate in opposite directions, the movement direction of the desiccant near different stirring components 11 is not consistent, which increases the degree of system disorder, avoids carbon fiber sedimentation, and facilitates carbon fiber decomposition, thereby improving the uniformity of carbon fiber dispersion in the desiccant.

[0035] It should be noted that the fact that at least two stirring elements 11 rotate in opposite directions means that the rotation directions of the stirring elements 11 are not all the same. At least two stirring elements 11 rotate in opposite directions, while the rotation directions of the remaining stirring elements 11 are the same as any one of the two opposite stirring elements 11. In a specific embodiment, the number of stirring elements 11 rotating in opposite directions is the same, so that the force driving the dissolving liquid to flow in different directions is the same. The dissolving liquid has approximately the same counterforce in both directions, resulting in an increase in the entropy of the dissolving liquid, which is conducive to the formation of a turbulent state.

[0036] In addition, the agitator 11 can apply pressure to the dissolving liquid in the lateral direction and drive the dissolving liquid to flow by rotating itself. It is understood that the agitator 11 can be constructed as a screw and blades spaced apart around the screw, or a long strip plate, or a fan blade, etc.

[0037] It should also be noted that each stirring component 11 has an axis 111, that is, the center of gravity of the stirring component 11 should be on this axis 111, so that when the stirring component 11 rotates around the axis 111, it will avoid damage such as breakage due to the center of gravity not being in the center of rotation.

[0038] Meanwhile, all the stirring components 11 are driven and connected to the driving component 2. All the stirring components 11 should be distributed at intervals on one plane of the driving component 2 so that the dissolving liquid can flow smoothly when it is driven to move, reduce the phenomenon of excessive speed in some areas, and avoid the accumulation of carbon fibers.

[0039] Furthermore, the axes 111 of all the stirring components 11 should be arranged in parallel so that the multiple stirring components 11 can stably drive the flow of the dissolving liquid, and can avoid the driving method being too complicated, thus reducing the risk of the structure being easily damaged.

[0040] In addition, the driving component 2 drives the stirring component 11 to rotate, and the stirring components 11 rotating in the opposite direction are also driven by the driving component 2. Therefore, the driving component 2 can be configured in various ways, such as:

[0041] The driving component 2 can be equipped with two independent driving elements with opposite rotation directions, which respectively drive the stirring components 11 with different rotation directions to rotate without interfering with each other; or,

[0042] The drive unit 2 is equipped with a drive element that rotates in only one direction. At this time, the drive unit 2 can be connected to a part of the stirring unit 11 that rotates in the same direction, and then connected to another part of the stirring unit 11 through reverse transmission methods such as bevel gears, helical gears, disc gears, linkage mechanisms, and belts with opposite surfaces, so that the stirring unit 11 has two different rotation directions.

[0043] Understandably, the rotational speed of the stirring component 11 in both directions can be the same or different.

[0044] Among them, the driving component 2 can be a motor or a combination of a motor and a transmission mechanism.

[0045] In one embodiment, see Figure 1 and Figure 2 At least two stirring elements 11 constitute a stirring group 10, and all stirring groups 10 are arranged at intervals. In any stirring group 10, at least two stirring elements 11 rotate in opposite directions. In this way, each stirring group 10 can drive the dissolving liquid to move in at least one direction, and multiple stirring groups 10 drive the dissolving liquid to move in different directions, thus stabilizing and maintaining the chaotic flow of the dissolving liquid.

[0046] It should be noted that at least two stirring elements 11 constitute a stirring group 10, that is, there are multiple stirring elements 11 in a stirring group 10, and the multiple stirring elements 11 are arranged at intervals in the stirring group 10 so that the dissolving liquid can flow under the drive of the stirring elements 11.

[0047] In addition, at least two stirring elements 11 in each stirring group 10 move in opposite directions, that is, at least two stirring elements 11 in each stirring group 10 rotate in opposite directions, and the rotation direction of the remaining stirring elements 11 is the same as that of any one of the two opposite stirring elements 11. This avoids the dissolving liquid rotating and flowing around the entire stirring element 11, which would increase the instability of the dissolving liquid flow.

[0048] The number of mixing components 11 in each mixing group 10 can be two, three, or four, and all mixing components 11 are spaced apart.

[0049] It should also be noted that the number of stirring groups 10 in stirring assembly 1 can be one or more.

[0050] When there is only one stirring group 10, the stirring group 10 drives the disintegration liquid to move in different directions to disperse and disintegrate the carbon fibers.

[0051] When there are multiple stirring groups 10 in the stirring assembly 1, and the multiple stirring groups 10 are arranged at intervals on the stirring assembly 1, and drive the dissolution liquid to flow, the flow of the dissolution liquid has multiple directions and presents a turbulent state.

[0052] Furthermore, see Figure 1 and Figure 2 In any stirring group 10, all the stirring elements 11 are spaced apart, and a flow gap 12 is provided between two adjacent stirring elements 11. In this way, the spaced-apart stirring elements 11 can prevent carbon fiber filaments from getting tangled on the stirring elements 11, and when the stirring elements 11 rotate, the stirring elements 11 in opposite directions drive the dispersing liquid through the flow gap 12 in the middle, which accelerates the flow of the dispersing liquid and increases the flow rate of the dispersing liquid, thereby speeding up the dispersion efficiency of the carbon fiber.

[0053] It should be noted that in the same stirring group 10, there is a flow gap 12 between two adjacent stirring elements 11, that is, there is a certain interval between adjacent stirring elements 11 so that the distance between the stirring elements 11 is not too close, so that the carbon fiber filaments are wrapped around the stirring elements 11. The flow gap 12 should not be too large, so that the stirring elements 11 rotating in opposite directions can drive the dissolving liquid through the flow gap 12.

[0054] Furthermore, when the dissolving liquid passes through the flow gap 12, the carbon fibers carried in the dissolving liquid will pass through the flow gap between the stirring groups from behind the stirring group under the drive of the stirring components, and flow to the front of the stirring group, so that it changes from a loose and disordered state to an ordered state immediately when passing through the flow gap 12; then, after passing through, it becomes loose and disordered again, which is conducive to the uniform dispersion of carbon fibers.

[0055] When the diaphoretic fluid passes through the flow gap 12, it moves at a relatively high speed under the action of the stirring member 11, and the flow direction of the diaphoretic fluid is perpendicular to the plane containing the axis 111 of the two stirring members 11.

[0056] When the stirring assembly 1 is provided with multiple stirring groups 10, the multiple stirring groups 10 are arranged at intervals. At this time, the flow direction of the dissolution liquid in each flow gap 12 in different stirring groups 10 is different, so as to avoid the dissolution liquid forming a stable flow.

[0057] In one embodiment, see Figure 3Each mixing group 10 includes two mixing elements 11 rotating in opposite directions. All mixing groups 10 are circumferentially spaced on the drive element 2 and form a central region, with the flow gaps 12 of all mixing groups 10 facing the central region. In this way, during operation, the flow direction of the dissolving liquid in the flow gaps 12 is towards the central region, and then it disperses from the central region, which is conducive to the formation of turbulence.

[0058] It should be noted that the flow gaps 12 of all stirring units 10 are oriented towards the central region, meaning that the dissolving liquid within the flow gaps 12 flows towards the central region. For details, please refer to... Figure 3 As shown by the dashed arrow in the image.

[0059] Specifically, see Figure 1 and Figure 2 The stirring assembly 1 includes three stirring groups 10, which are arranged in a triangle on the drive unit 2. Each stirring group 10 includes two stirring elements 11 with opposite rotation directions. A flow gap 12 is provided between the two stirring elements 11. The flow direction of the dissolving liquid in the flow gap 12 of each stirring group 10 is towards the center of the triangle, so that the dissolving liquid flowing out of the flow gap 12 can converge and disperse at the center to form turbulence.

[0060] In one embodiment, such as Figure 4 As shown, the stirring component 11 includes a rod 112 and blades 113. The blades 113 extend spirally around the rod 112 along the axis 111 of the rod 112. In this way, when driving the dissolving liquid to flow, the blades 113 extending spirally around the rod 112 can also drive the dissolving liquid to flow upward or downward, impacting the dissolving liquid from multiple angles. Furthermore, when the dissolving liquid moves upward under the action of the blades 113, it can also prevent the sedimentation and accumulation of carbon fibers, thus reducing sedimentation.

[0061] It should be noted that the axis 111 of the rod 112 is the same as the axis 111 of the stirring element 11. Driving the rod 112 to rotate and causing the blades 113 to rotate is the rotation of the stirring element 11.

[0062] Furthermore, the blade 113 extends spirally around the rod 112 along the axis 111 of the rod 112, that is, the blade 113 extends spirally around the rod 112 outside the rod 112, and it can extend counterclockwise or clockwise. Specifically, in one embodiment, different rotation directions of the blade 113 can be provided on the stirring member 11 with different rotation directions, specifically divided into the following four types:

[0063] When the blades 113 of a stirring element 11 extend clockwise upward along the axis 111 on the periphery of the rod 112, and the stirring element 11 rotates clockwise, the surrounding dissolving liquid will be squeezed downward by the blades 113 while rotating clockwise.

[0064] When the blades 113 of a stirring element 11 extend clockwise upward along the axis 111 on the periphery of the rod 112, and the stirring element 11 rotates counterclockwise, the surrounding dissolving liquid will be lifted upward by the blades 113 while rotating counterclockwise.

[0065] When the blades 113 of a stirring element 11 extend counterclockwise upward along the axis 111 on the periphery of the rod 112, and the stirring element 11 rotates clockwise, the surrounding dissolving liquid will be squeezed downward by the blades 113 while rotating clockwise.

[0066] When the blade 113 of a stirring element 11 extends counterclockwise upward along the axis 111 on the periphery of the rod 112, and the stirring element 11 rotates counterclockwise, the surrounding dissolving liquid will be lifted upward by the blade 113 while rotating counterclockwise.

[0067] Of course, the above four types of mixing components 11 can be combined in any way according to different needs to adapt to different application scenarios and improve the efficiency and uniformity of short-cut carbon fiber dispersion.

[0068] In one embodiment, such as Figure 1 and Figure 2 As shown, the stirring device also includes a lifting device 4, which controls the drive component 2 to move along the axis 111 of the stirring component 11. In this way, by using the lifting device 4 to control the movement of all the stirring components 11 along the axis 111, they can move downwards into the leaching liquid when stirring is needed, and move upwards to keep the stirring components 11 away from the leaching liquid when not needed, thus avoiding any impact on the leaching liquid and facilitating subsequent filling operations.

[0069] It should be noted that the lifting device 4 can control the drive component 2 to move up and down along the axis 111 of the stirring component 11. At the same time, the drive component 2 is driven to connect with the stirring component 11. Therefore, the lifting device 4 controls the stirring assembly 1 to move up and down along the axis 111 of the stirring component 11.

[0070] Optionally, the lifting device 4 can control the stirring assembly 1 to move up and down in various ways, including but not limited to gears, slide rails, belts, etc.

[0071] In conjunction with the above embodiments, the lifting device 4 can control the stirring component 11 to extend into or away from the opening 30 of the storage component 3. When it is necessary to decompose the short-cut carbon fiber, the lifting device 4 controls the stirring component 1 to move upward so that the stirring component 1 no longer occupies the opening 30 of the storage component 3. Short-cut carbon fiber and delamination liquid are added from the opening 30. Then, the lifting device 4 controls the stirring component 1 to move downward so that the stirring component 11 is inserted into the delamination liquid for stirring.

[0072] It should also be noted that the lifting device 4 can also drive the stirring component 1 to move horizontally. When the stirring component 1 moves to the top, the lifting device 4 can drive the stirring component 1 to move horizontally so that the stirring component 1 can be moved away from the top of the storage chamber opening 30, which facilitates the loading and unloading of storage components 3, adding materials and other operations.

[0073] Further, refer to Figure 1 The lifting device 4 includes a support base 41, a support frame 42, a connector 43, and a lifter 44. The support frame 42 is fixedly connected to the support base 41. The connector 43 is slidably connected to the support frame 42 and fixed to the drive component 2. The lifter 44 is used to drive the connector 43 to slide on the support frame 42. In this way, the support base 41 supports the entire lifting device 4, and the connector 43 is slidably connected on the support frame 42 to drive the stirring assembly 1 to move. The structure is simple and not easily damaged.

[0074] It should be noted that the support base 41 is used to support the entire lifting device 4. It can be extended on the horizontal plane to increase the contact area on the horizontal plane and make the lifting device 4 stable.

[0075] Meanwhile, the connector 43 is slidably connected to the support frame 42, and its sliding direction is the axis 111 direction of the stirring component 11, so that the connector 43 drives the stirring assembly 1 to move, and the support frame 42 can provide the movement stroke of the connector 43 in the axis 111 direction of the stirring component 11. Therefore, the support has a certain length in the axis 111 direction of the stirring component 11.

[0076] Specifically, see Figure 1 and Figure 2 The support base 41 extends along the horizontal plane, and the support frame 42 extends upward along the axis 111 of the stirring component 11 at one end of the support base 41. The connecting member 43 is slidably connected on the support frame 42 to drive the stirring assembly 1 to move along the axis 111 of the stirring component 11.

[0077] Alternatively, the lifting device 44 may drive the connecting member 43 to move in a manner that is, but is not limited to, a motor.

[0078] Furthermore, such as Figure 1 As shown, there is an operating space 45 between the connector 43 and the support base 41. The drive member 2 is disposed on the side of the connector 43 facing the operating space 45. The stirring assembly 1 is located within the operating space 45 and is located on the side of the drive member 2 facing the support base 41. In this way, the drive member 2 is connected to the side of the connector 43 facing the operating space 45, so that the stirring assembly 11 is located within the operating space 45 and always moves within the operating space 45, which increases the stability of the device.

[0079] It should be noted that the operating space 45 is a space enclosed in three directions by the support member, the support frame 42 and the connecting member 43 on the lifting device 4, which is used for the mixing assembly 1 to carry out mixing operations.

[0080] The connector 43 is located above the support base 41 so that the drive unit 2 and the stirring assembly 1 connected thereto are located within the operating space 45.

[0081] Based on the above embodiments, refer to Figure 1 The storage component 3 is located on the support base 41, and the connecting component 43 is located above the storage component 3 and controls the stirring assembly 1 to extend into or pull out of the storage component 3.

[0082] In addition, this application also provides a carbon fiber decomposition system, including a storage unit 3 and the above-mentioned stirring device, wherein the storage unit is used to hold the decomposition liquid.

[0083] The aforementioned carbon fiber decomposition system includes a stirring device. A driving component 2 drives multiple stirring components 11 to rotate around their own axis 111, thereby driving the decomposition liquid and short-cut carbon fibers to move. Furthermore, by using stirring components 11 that rotate in opposite directions, the movement direction of the decomposition liquid near different stirring components 11 is not consistent, which increases the degree of system disorder, avoids carbon fiber sedimentation, and promotes carbon fiber decomposition, thereby improving the uniformity of carbon fiber dispersion in the decomposition liquid.

[0084] In one embodiment, see Figure 1 and Figure 2 The carbon fiber decomposition system also includes a storage unit 3 for storing the decomposition liquid, with a stirring member 11 partially extending into the decomposition liquid. In this way, while the storage unit 3 stores the decomposition liquid, the stirring member 11 can also extend into the storage unit 3 to stir the decomposition liquid, thereby improving the dispersion efficiency of the decomposition liquid.

[0085] It should be noted that the storage component 3 is used to store the dissolving liquid, and it has an opening 30 for pouring in the dissolving liquid and for inserting all the stirring components 11.

[0086] Specifically, see Figure 1 and Figure 2 The storage unit 3 is cylindrical with an opening 30 at the top. The desolvation liquid and short-cut carbon fibers are put into the storage unit 3 through the opening 30, and the agitator 11 is inserted into the opening 30 to agitate the desolvation liquid.

[0087] It should also be noted that the storage unit 3 can be movably mounted on the mixing device. When adding materials before mixing or after mixing, the storage unit 3 can be directly removed for operation, which is convenient.

[0088] Furthermore, the mixing device includes multiple storage units 3, so that the next storage unit 3 is filled while the previous storage unit 3 is being mixed, and the next storage unit 3 can be directly replaced after the previous storage unit 3 has finished mixing, thus improving the efficiency of the operation.

[0089] Furthermore, this application also provides a carbon fiber decomposition control method, applied to the aforementioned carbon fiber decomposition system, comprising the following steps:

[0090] S100: Control the stirring assembly 1 to move toward one side of the storage container 3, and make one end of the stirring assembly 11 extend into the dissolution liquid of the storage container 3;

[0091] S200: Control the drive unit 2 to work, drive the stirring unit 11 to rotate around its respective axis 111, and control at least two stirring units 11 to rotate in opposite directions.

[0092] The aforementioned carbon fiber decomposition control method is applied to the aforementioned carbon fiber decomposition system. The driving component 2 drives multiple stirring components 11 to rotate around their own axis 111, thereby driving the decomposition liquid and short-cut carbon fibers to move. Furthermore, by using stirring components 11 that rotate in opposite directions, the movement direction of the decomposition liquid near different stirring components 11 is not consistent, which increases the degree of system disorder, avoids carbon fiber sedimentation, and promotes carbon fiber decomposition, thereby improving the uniformity of carbon fiber dispersion in the decomposition liquid.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
