Description

Technical Field

[0001] This application relates to the field of glass container manufacturing technology, specifically a method for manufacturing a glass container and a glass container. Background Technology

[0002] In related technologies, glass containers are generally produced using either pressing or blowing methods. Pressing involves pouring molten glass into a mold and then pressing it into the desired shape using pressure; this method is generally suitable for producing relatively simple glass containers. Blowing involves placing molten glass into a mold and then blowing air into the molten glass to form the desired shape; this method is suitable for producing more complex glass containers. However, the wall thickness of glass containers produced using this method is difficult to control, resulting in low accuracy in the external shape and internal dimensional accuracy. Furthermore, blowing glass containers are prone to poor processing quality. For example, products produced using molds may have parting marks on the surface, or blown glass containers are prone to defects such as uneven surfaces, cracks, and partial collapse. Summary of the Invention

[0003] This application provides a method for manufacturing a glass container and a glass container to solve the problem of how to improve the processing accuracy of glass containers and reduce the probability of defective glass containers.

[0004] On one hand, this application provides a method for manufacturing a glass container, comprising the following steps:

[0005] Step S1: Fabricate an annular glass component. The annular glass component has a hollow cavity. The hollow cavity extends through both ends of the annular glass component in a predetermined direction to form a first opening and a second opening corresponding to the two ends of the annular glass component, respectively.

[0006] Step S2: A first welding surface is machined on the end face of the first opening, and a second welding surface is machined on the end face of the second opening;

[0007] Step S3: Connect the first flat glass substrate and the second flat glass substrate to the first welding surface and the second welding surface respectively; wherein, the outer contour of the first flat glass substrate coincides with the outer contour of the end face of the first opening, so that the first flat glass substrate covers the first opening, and the outer contour of the second flat glass substrate coincides with the outer contour of the end face of the second opening, so that the second flat glass substrate covers the second opening.

[0008] In one embodiment, step S1 includes:

[0009] Step S11: Provide a mold with an annular cavity;

[0010] Step S12: Pour molten glass into the annular mold cavity and press it into shape using the mold to obtain the annular glass component.

[0011] In one embodiment, step S3 includes the following steps:

[0012] Step S31: Align the first flat glass substrate with the first welding surface, and align the second flat glass substrate with the second welding surface to obtain a glass assembly;

[0013] Step S32: By heating the first welding surface and the second welding surface, the first flat glass substrate is welded to the first welding surface, and the second flat glass substrate is welded to the second welding surface.

[0014] In one embodiment, step S3 includes the following steps:

[0015] Step S301: Align the first flat glass substrate with the first welding surface, and weld the first flat glass substrate to the first welding surface by aligning the first welding surface.

[0016] Step S302: The second flat glass substrate is aligned and fitted with the second welding surface, and the second flat glass substrate is welded to the second welding surface by aligning the second welding surface.

[0017] In one embodiment, prior to step S3, the following step is included:

[0018] Provide glass sheets of uniform thickness;

[0019] The first flat glass substrate and the second flat glass substrate are prepared using the glass sheet;

[0020] The annular glass component, the first flat glass substrate, and the second flat glass substrate are cleaned.

[0021] In one embodiment, step S2 includes: attaching glass welding material to the end face of the first opening using a screen printing process or a vapor deposition process to form the first welding surface; attaching glass welding material to the end face of the first opening using a screen printing process or a vapor deposition process to form the first welding surface.

[0022] On the other hand, this application provides a glass container, which is prepared by the glass container manufacturing method of any of the above embodiments.

[0023] In one embodiment, the sidewalls of the hollow cavity have the same cross-sectional profile at any position in the predetermined direction, and the annular glass component, the first flat glass substrate, and the second flat glass substrate are all transparent glass.

[0024] In one embodiment, the sidewall of the hollow cavity includes multiple planes, and any two adjacent planes are smoothly transitioned by an arc.

[0025] In one embodiment, the cross-sectional profile of the sidewall of the hollow cavity at any position in the predetermined direction is symmetrical about a first straight line, and the cross-sectional profile of the outer wall of the annular glass member at any position in the predetermined direction is symmetrical about a second straight line, wherein the first straight line and the second straight line coincide in the predetermined direction.

[0026] The aforementioned method for manufacturing a glass container and the glass container itself involve machining a first welding surface and a second welding surface on the end faces of the first and second openings of a ring-shaped glass component. These first and second welding surfaces are then used to connect a first flat glass substrate and a second flat glass substrate, respectively. Thus, the ring-shaped glass component, due to its first and second openings, forms a relatively entirely closed glass container. This ring-shaped glass component is simple and can be manufactured using processes such as pressing, resulting in controllable processing precision and reducing the likelihood of quality defects. Simultaneously, the high dimensional accuracy of the first and second flat glass substrates, along with their ease of precision machining such as cutting or grinding, ensures processing accuracy and minimizes the risk of quality defects. Therefore, manufacturing a glass container using the method described in this application not only improves the processing precision of the glass container but also reduces the probability of quality defects.

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.

[0041] It should be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0042] The terms “vertical,” “horizontal,” “up,” “down,” “left,” “right,” and similar expressions are for illustrative purposes only and do not represent the only possible implementation.

[0043] It should be understood that the terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” and “horizontal,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and 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. Therefore, they should not be construed as limitations on this application.

[0044] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In related technologies, glass containers are generally produced using either pressing or blowing methods. Pressing involves pouring molten glass into a mold and then using pressure to mold it into the desired shape. Blowing involves placing molten glass into a mold and then blowing air into it to form the desired shape; this method is suitable for producing glass containers with more complex shapes.

[0046] The inventors discovered that the pressing method has certain limitations, suitable for producing relatively simple glass containers, but unable to meet the production needs of more complex shapes. While the blowing method can meet the needs of producing more complex glass containers, the wall thickness of glass containers made by the blowing method is difficult to control, resulting in low dimensional accuracy in the shape and internal cavity of the glass containers. In addition, glass containers processed by the blowing method are also prone to poor processing quality. For example, products blown using molds may have parting marks on the surface, or blown glass containers are prone to defects such as uneven surfaces, cracks, and partial collapse.

[0047] In response, the inventors, through research, proposed a method for manufacturing glass containers, applicable to both simple and complex shapes. This method produces glass containers with high dimensional accuracy. Specifically, the manufacturing method described in this application facilitates control over the wall thickness of the glass container, thereby improving the dimensional accuracy of its shape and internal cavity, and ultimately enhancing the processing precision. Furthermore, the glass containers manufactured using this method do not suffer from defects such as parting marks on the surface of products blown from molds in related technologies, or surface irregularities, cracks, and partial collapses common in blown glass containers.

[0048] Specifically, in combination Figures 1 to 3 As shown, one embodiment of this application provides a method for manufacturing a glass container, including the following steps:

[0049] Step S1: Fabricate an annular glass component 10. The annular glass component 10 has a hollow cavity 11. The hollow cavity 11 extends through both ends of the annular glass component 10 in a predetermined direction to form a first opening 12 and a second opening 13 corresponding to the two ends of the annular glass component 10, respectively.

[0050] In step S2, a first welding surface 121 is machined on the end face of the first opening 12, and a second welding surface 131 is machined on the end face of the second opening 13.

[0051] In step S3, the first flat glass substrate 20 and the second flat glass substrate 30 are connected to the first welding surface 121 and the second welding surface 131, respectively; wherein, the outer contour of the first flat glass substrate 20 coincides with the outer contour of the end face of the first opening 12, so that the first flat glass substrate 20 covers the first opening 12, and the outer contour of the second flat glass substrate 30 coincides with the outer contour of the end face of the second opening 13, so that the second flat glass substrate 30 covers the second opening 13.

[0052] The aforementioned method for manufacturing a glass container and the glass container thereof involve machining a first welding surface 121 and a second welding surface 131 on the end faces of the first opening 12 and the second opening 13 of the annular glass component 10. The first welding surface 121 and the second welding surface 131 are then used to connect the first flat glass substrate 20 and the second flat glass substrate 30, respectively. Thus, the annular glass component 10, due to its first opening 12 and the second opening 13, forms a relatively entirely closed glass container. This annular glass component 10 is simple and can be manufactured using processes such as pressing, resulting in controllable processing precision and reducing the likelihood of quality defects. Simultaneously, the first flat glass substrate 20 and the second flat glass substrate 30 themselves have high dimensional accuracy and are easy to process with precision finishing processes such as cutting or grinding, ensuring processing precision and reducing the likelihood of quality defects. Therefore, manufacturing a glass container using the method described in this application not only improves the processing precision of the glass container but also reduces the probability of quality defects.

[0053] Combination Figure 4 As shown, in some embodiments, step S1 includes:

[0054] Step S11: Provide a mold with an annular cavity.

[0055] Step S12: Pour molten glass into an annular mold cavity and press it into shape using a mold to obtain an annular glass component 10.

[0056] In this embodiment, the annular glass component 10 can be formed by pressing, thereby avoiding the problem of uneven wall thickness caused by blow molding when glass containers with irregular cavities are difficult to press molded in related technologies, thus ensuring processing accuracy.

[0057] In some embodiments, this method of pressing and forming the annular glass component 10 using an annular mold cavity can achieve a profile tolerance of the annular glass component 10 within ±0.1mm.

[0058] It should be noted that in step S3, the first flat glass substrate 20 and the second flat glass substrate 30 can be connected to the annular glass component 10 simultaneously, or they can be operated in separate steps.

[0059] For example, combining Figure 5 As shown, in some embodiments, step S3 includes the following steps:

[0060] Step S31: Align the first flat glass substrate 20 with the first welding surface 121, and align the second flat glass substrate 30 with the second welding surface 131 to obtain a glass assembly.

[0061] In step S32, by heating the first welding surface 121 and the second welding surface 131, the first flat glass substrate 20 is welded to the first welding surface 121 and the second flat glass substrate 30 is welded to the second welding surface 131.

[0062] In this embodiment, because the first flat glass substrate 20 is aligned with the first welding surface 121 and the second flat glass substrate 30 is aligned with the second welding surface 131, the assembly positions of the components of the obtained glass assembly are precise. Furthermore, by performing subsequent welding operations on the glass assembly, welding efficiency can be improved, and the consistency of the welding conditions of the first flat glass substrate 20 and the second flat glass substrate 30 can be maintained, thereby contributing to improving the overall structural strength of the glass container.

[0063] After tensile testing, the first flat glass substrate 20 and the second flat glass substrate 30 are fused to the annular glass component 10, and the pull force reaches 50% to 65% of the tensile strength of the parent materials of the first flat glass substrate 20 and the second flat glass substrate 30.

[0064] Of course, in other embodiments, the second flat glass substrate 30 can be welded to the first welding surface 121 after the first flat glass substrate 20 is welded to the first welding surface 121.

[0065] Specifically, in combination Figure 6 As shown, step S3 includes the following steps:

[0066] Step S301: Align and fit the first flat glass substrate 20 with the first welding surface 121, and weld the first flat glass substrate 20 to the first welding surface 121 by aligning the first welding surface 121.

[0067] In step S302, the second flat glass substrate 30 is aligned and fitted with the second welding surface 131, and the second flat glass substrate 30 is welded to the second welding surface 131 by aligning the second welding surface 131.

[0068] In this embodiment, the first flat glass substrate 20 and the second flat glass substrate 30 are connected to the annular glass component 10 by step-by-step welding, thereby enabling independent control of the thermal expansion coefficients at the two connection interfaces (i.e., the first welding surface 121 and the second welding surface 131), so that the thermal expansion coefficients of the first flat glass substrate 20 and the first welding surface 121 are matched, and the thermal expansion coefficients of the second flat glass substrate 30 and the second welding surface 131 are matched, thereby reducing the probability of microcracks caused by shrinkage difference during cooling.

[0069] Furthermore, "thermal isolation" can also be achieved through step-by-step welding, that is, avoiding deformation of the annular glass component 10 caused by overall high temperature, which helps to improve the processing accuracy of the glass container and reduce the probability of cracks appearing in the annular glass component 10.

[0070] In some embodiments, the above-mentioned welding can be carried out by low-temperature selective welding, that is, only the first welding surface 121 and the second welding surface 131 are locally heated instead of the whole high-temperature sintering, thereby reducing energy consumption.

[0071] During the alignment and fitting of the first flat glass substrate 20 with the first welded surface 121, and the alignment and fitting of the second flat glass substrate 30 with the second welded surface 131, a machine vision-assisted positioning system can be used to improve alignment accuracy. In some embodiments, the positional deviation between the first flat glass substrate 20 and the first welded surface 121 is less than or equal to 50 μm. The positional deviation between the second flat glass substrate 30 and the second welded surface 131 is less than or equal to 50 μm.

[0072] In some embodiments, the first welding surface 121 and the second welding surface 131 may be pretreated with abrasive jet to make the roughness Ra≤0.8μm, so as to facilitate the uniform flow of molten glass and reduce the thickness fluctuation of the material during welding, thereby further improving the processing accuracy of the glass container.

[0073] In some implementations, the following step is included before step S3:

[0074] We provide glass sheets of uniform thickness.

[0075] A first flat glass substrate 20 and a second flat glass substrate 30 are prepared using glass plates.

[0076] In some embodiments, the thickness of the glass sheet can be from 0.5 mm to 4 mm. The thickness of the glass sheet is not limited here and can be selected according to the design requirements of the glass container. For example, the thickness of the glass sheet can be 0.5 mm, 1 mm, 1.5 mm, 2.5 mm, 3.5 mm, or 4 mm.

[0077] Because the glass sheets have a uniform thickness, the thickness of the first flat glass substrate 20 and the second flat glass substrate 30 can be precisely controlled when using these glass sheets to prepare them. It should be noted that, depending on the size design requirements of the glass container, the first flat glass substrate 20 and the second flat glass substrate 30 can be made of glass sheets with the same thickness, thus ensuring that the thicknesses of the first flat glass substrate 20 and the second flat glass substrate 30 are identical. Alternatively, depending on the size design requirements of the glass container, the thicknesses of the first flat glass substrate 20 and the second flat glass substrate 30 can also differ.

[0078] The thickness of the first flat glass substrate 20 and the second flat glass substrate 30 is not limited here. In addition, in some embodiments, the first flat glass substrate 20 and the second flat glass substrate 30 may also be made of glass materials with uniformly varying thicknesses.

[0079] Accordingly, the annular glass member 10 can be rectangular, circular, or elliptical. In some embodiments, the annular glass member 10 can be an annular structure enclosed by multiple arcuate members; for example, the outer periphery of the annular glass member 10 includes at least two intersecting arcs.

[0080] In some implementations, the following step is included before step S3:

[0081] Clean the annular glass component 10, the first flat glass substrate 20, and the second flat glass substrate 30.

[0082] This ensures that the annular glass component 10, the first flat glass substrate 20, and the second flat glass substrate 30 are in a clean state, which helps to improve the welding stability.

[0083] In some embodiments, step S2 includes: attaching glass welding material to the end face of the first opening 12 by screen printing or vapor deposition to form a first welding surface 121; attaching glass welding material to the end face of the first opening 12 by screen printing or vapor deposition to form a first welding surface 121.

[0084] In this embodiment, since the glass welding material is used to form a first welding surface 121 and a second welding surface 131 on the two end faces of the annular glass component 10 by screen printing or vapor deposition, the welding stability can be improved by forming the first welding surface 121 and the second welding surface 131 through the glass welding material compared to directly connecting the first flat glass substrate 20 and the second flat glass substrate 30 to the annular glass component 10. Furthermore, the thermal expansion coefficient of the glass welding material is easy to match, ensuring that the thermal expansion coefficients of the first flat glass substrate 20 and the first welding surface 121 are matched, and the thermal expansion coefficients of the second flat glass substrate 30 and the second welding surface 131 are matched, thereby reducing the probability of microcracks caused by shrinkage differences during cooling.

[0085] On the other hand, another embodiment of this application provides a glass container, which is prepared by the glass container manufacturing method of any of the above embodiments.

[0086] In the aforementioned method for manufacturing glass containers, a first welding surface 121 and a second welding surface 131 are machined on the end faces of the first opening 12 and the second opening 13 of the annular glass component 10. These welding surfaces 121 and 131 are then used to connect the first flat glass substrate 20 and the second flat glass substrate 30, respectively. Thus, the annular glass component 10, with its first opening 12 and second opening 13, forms a relatively entirely closed glass container. This annular glass component 10 is simple and can be manufactured using processes such as pressing, resulting in controllable processing precision and reducing the likelihood of quality defects. Simultaneously, the first flat glass substrate 20 and the second flat glass substrate 30 themselves have high dimensional accuracy and are easy to process with precision finishing processes such as cutting or grinding, ensuring processing precision and minimizing the likelihood of quality defects. Therefore, using the glass container manufacturing method of this application not only improves the processing precision of the glass container but also reduces the probability of quality defects.

[0087] It should be noted that, due to the manufacturing method of the glass container in this application, the glass container is assembled by combining an annular glass component 10, a first flat glass substrate 20, and a second flat glass substrate 30. The annular glass component 10 has a first opening 12 and a second opening 13 at both ends, allowing for manufacturing processes such as pressing. Therefore, by adopting the manufacturing method of the glass container in this application, processing accuracy can be improved when manufacturing glass containers with a cubic cavity 11, or when manufacturing glass containers with irregular shapes such as curved surfaces or sharp edges in the cavity 11.

[0088] For ease of understanding, the structure of glass containers in some embodiments is described below, but this does not mean that the shape and size of the glass containers are limited to this.

[0089] Combination Figure 2 and Figure 3 As shown, the outer wall surface of the annular glass component 10 includes a top surface 10a, a first side surface 10b, a bottom surface 10c, and a second side surface 10d that are sequentially adjacent to each other.

[0090] In some embodiments, the top surface 10a and the bottom surface 10c are arranged in parallel, and the first side surface 10b and the second side surface 10d are arranged in parallel. Understandably, the first weld surface 121 and the second weld surface 131 are located on both sides of the annular glass member 10. The top surface 10a, the first side surface 10b, the bottom surface 10c, and the second side surface 10d can be transitioned to the first weld surface 121 and the second weld surface 131 by right-angle chamfering or rounded chamfering, thereby making the overall shape of the annular glass member 10 rounded and aesthetically pleasing.

[0091] In some embodiments, the hollow cavity 11 serves as a cavity enclosed by the inner wall of the annular glass component 10. The hollow cavity 11 may also include multiple surfaces. For example, the sidewall of the hollow cavity 11 includes multiple planes, with any two adjacent planes smoothly transitioning through an arc, so that the sidewall of the hollow cavity 11 is rounded and without abrupt edges, thereby enhancing the aesthetics of the glass container.

[0092] like Figure 7 As shown, the glass container may have a container opening 14. The container opening 14 may be provided on the top surface 10a. The container opening 14 may be integrally formed with the annular glass member 10.

[0093] In other embodiments, the container opening 14 may also be integrally formed on the first flat glass substrate 20 or the second flat glass substrate 30.

[0094] Combination Figure 7 and Figure 8 As shown, in some embodiments, the sidewalls of the hollow cavity 11 include a top wall 11a, a first sidewall 11b, a bottom wall 11c, and a second sidewall 11d. The top wall 11a corresponds to the top surface 10a, the first sidewall 11b corresponds to the first side surface 10b, the bottom wall 11c corresponds to the bottom surface 10c, and the second sidewall 11d corresponds to the second side surface 10d. Thus, the wall thickness of the annular glass member 10 is defined between the corresponding wall surfaces.

[0095] The annular glass member 10 has different wall thicknesses on different sides in its circumferential direction.

[0096] For example, the top is parallel to the top surface 10a, the bottom wall 11c is parallel to the bottom surface 10c, and the distance between the bottom wall 11c and the bottom surface 10c is greater than the distance between the top and the top surface 10a.

[0097] like Figure 8As shown, the top wall 11a and the first side wall 11b form a first included angle α. In some embodiments, the value of the first included angle α ranges from 82° to 90°, for example, the value of the first included angle α is 82°, 85°, 87°, 89° or 90°. Understandably, when the first included angle α is 90°, the top wall 11a and the first side wall 11b are set at a right angle.

[0098] The top wall 11a and the second side wall 11d form a second included angle β. In some embodiments, the value of the second included angle β ranges from 82° to 90°, for example, the value of the second included angle β is 82°, 85°, 87°, 89° or 90°. Understandably, when the second included angle β is 90°, the top wall 11a and the second side wall 11d are arranged at a right angle.

[0099] When the first included angle α is acute, the distance between the first sidewall 11b and the first side surface 10b gradually increases in the direction away from the top wall 11a. Thus, the annular glass member 10 has a uniformly thickened wall thickness on the side corresponding to the first sidewall 11b.

[0100] Correspondingly, when the second included angle β is acute, the distance between the second sidewall 11d and the second side surface 10d gradually increases in the direction away from the top wall 11a. Thus, the annular glass member 10 is uniformly thickened on the side corresponding to the second sidewall 11d.

[0101] It should be noted that in the above embodiments, the first sidewall 11b and the second sidewall 11d can be planes. In some embodiments, the first sidewall 11b and the second sidewall 11d can also be curved surfaces with gradually changing curvature.

[0102] The dimensions of each surface of the annular glass member 10 and the wall thickness at each location are not limited here. For example, the width of the annular glass member 10, i.e., the distance between the first side surface 10b and the second side surface 10d, is 10mm to 75mm.

[0103] In some embodiments, the sidewalls of the hollow cavity 11 have the same cross-sectional profile at any position in a predetermined direction, and the annular glass component 10, the first flat glass substrate 20, and the second flat glass substrate 30 are all transparent glass. Thus, by utilizing this transparent glass material, the profile of the sidewalls of the hollow cavity 11 can be observed, thereby making the glass container appear transparent and aesthetically pleasing.

[0104] Combination Figure 9As shown, in some embodiments, the cross-sectional profile of the sidewall of the hollow cavity 11 at any position in a predetermined direction is symmetrical about a first straight line, and the cross-sectional profile of the outer wall of the annular glass member 10 at any position in a predetermined direction is symmetrical about a second straight line. The first and second straight lines coincide in the predetermined direction. Understandably, in this embodiment, the overall structure of the annular glass member 10 is symmetrical about the plane defined by the first and second straight lines to facilitate the fabrication of a symmetrical and harmonious glass container. Understandably, in this embodiment, the first included angle α is equal to the second included angle β.

[0105] Combination Figure 10 As shown, the first welded surface 121 and the bottom surface 10c form a third included angle γ. In some embodiments, the value of the third included angle γ ranges from 80° to 90°. For example, the value of the second included angle β is 80°, 85°, 87°, 89°, or 90°. Understandably, when the third included angle γ is 90°, the first welded surface 121 and the bottom surface 10c are set at a right angle.

[0106] The second welded surface 131 and the bottom surface 10c form a fourth included angle θ. In some embodiments, the value of the fourth included angle θ is in the range of 80° to 90°, for example, the value of the fourth included angle θ is 80°, 85°, 87°, 89° or 90°. Understandably, when the fourth included angle θ is 90°, the second welded surface 131 and the bottom surface 10c are set at a right angle.

[0107] Both the third included angle γ and the fourth included angle θ are acute angles. At this time, the thickness of the annular glass component 10 in a predetermined direction, that is, the distance between the first welded surface 121 and the second welded surface 131, gradually decreases in the direction away from the bottom surface 10c. Thus, the annular glass component 10 has a shape that is wide at the bottom and narrow at the top, which is beneficial to the stability of the glass container when it is placed on the platform surface, and also has an aesthetic appeal.

[0108] 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.

[0109] The above embodiments merely illustrate 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 this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive 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.
