Description

Technical Field

[0001] This application relates to the field of clothing care technology, and in particular to a clothing treatment drum and drying device. Background Technology

[0002] Taking clothes dryers as an example, some devices have a functional layer attached to the inside of the drying drum. This functional layer provides functions such as moisturizing and sterilization. However, in related technologies, the functional layer is designed to fit snugly against the inner drum, making it inconvenient to disassemble and assemble. Utility Model Content

[0003] This application provides a clothes processing drum and a clothes drying device, which can improve the efficiency of disassembly and assembly.

[0004] Firstly, the garment processing tube includes:

[0005] tube body; and

[0006] A functional layer component covers the circumferential inner surface of the cylinder body and has a first end and a second end opposite to each other in the circumferential direction, with the first end and the second end spaced apart.

[0007] At least one of the first end and the second end is provided with a handle, which is configured to expose a portion of the circumferential inner surface of the cylinder.

[0008] In one embodiment, the tube body is provided with a clothing loading / unloading opening, and the handle is located on the side of the functional layer component near the clothing loading / unloading opening.

[0009] In one embodiment, the cylindrical body includes:

[0010] The main body of the cylinder has a circumferential inner surface formed thereon;

[0011] The front cover is connected to one end of the main body of the tube and forms the opening for taking out and putting in clothes. Along the axial direction of the tube body, the handle is spaced apart from the front cover.

[0012] In one embodiment, the handle portion is configured as a handle groove, which opens toward the other end of the functional layer assembly along the circumferential direction, and a portion of the inner circumferential surface of the cylinder body is exposed in the handle groove.

[0013] In one embodiment, a lifting rib is also included. The cylinder body is provided with a first connecting portion, and the lifting rib is provided with a second connecting portion. The handle groove is disposed to avoid the first connecting portion and / or the second connecting portion. The first connecting portion and the second connecting portion are aligned and connected. The lifting rib presses the functional layer component onto the circumferential inner surface of the cylinder body.

[0014] In one embodiment, the first connecting portion protrudes towards the inner side of the cylinder and passes through the handle groove, and the sidewall of the handle groove is spaced apart from the first connecting portion.

[0015] In one embodiment, the projection of the lifting rib on the circumferential inner surface overlaps the projection of the handle groove on the circumferential inner surface.

[0016] In one embodiment, the functional layer component includes a plurality of the handles, which are arranged at intervals along the axial direction of the cylinder body.

[0017] In one embodiment, the component further includes a lifting rib, and the functional layer component is provided with at least two positioning holes for cooperating with the lifting rib. Along the axial direction of the cylinder body, the at least two positioning holes and a plurality of the handle portions are alternately spaced.

[0018] In one embodiment, the functional layer component includes a first layered structure and a second layered structure. The first layered structure contacts the tubular body and serves as a support structure for generating a radially outward force on the tubular body, so that the functional layer component can abut against the circumferential inner surface of the tubular body. The second layered structure is located radially inside the first layered structure along the garment processing tubular body and serves as the external structure of the garment processing tubular body.

[0019] At least one of the first layered structure and the second layered structure serves as a functional structure.

[0020] In one embodiment, the functional layer component further includes an adhesive layer disposed between the first layered structure and the second layered structure, and bonding the first layered structure and the second layered structure together.

[0021] Secondly, clothes drying equipment includes:

[0022] Air duct;

[0023] And the garment processing tube described in any of the above, wherein the air duct is connected to the garment processing chamber inside the garment processing tube and is used to introduce airflow into the garment processing chamber.

[0024] Based on the above embodiments, through the handle at the end of the composite plate structure, the user can obtain a point of force through the exposed part of the cylinder body. This not only increases the contact area with the functional layer components by operating the handle and obtains a force application method that is easy to perform disassembly and assembly operations, but also allows the user to contact the cylinder body through the handle when removing the functional layer components, so as to further facilitate the separation of the functional layer components from the cylinder body.

[0025] Because the handles are located at the ends, and the first and second ends are spaced apart, more of the cylinder body is exposed, making it easier for the user to manipulate the handles. During assembly and disassembly, the user has more operating space between the two ends, facilitating the process. During disassembly, manipulating the handles to detach the end of the functional layer component from the cylinder body makes it easier to lift that end to separate the remaining parts of the functional layer component, improving disassembly efficiency. During installation, adjusting the handles also facilitates alignment of the two ends of the composite plate structure, improving assembly efficiency and accuracy. Attached Figure Description

[0037] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0040] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] This application provides a clothes drying device, which can be a dryer, washer-dryer combo, etc. The drying device includes an air duct and a clothes handling drum. The clothes handling drum has a clothes handling chamber for processing clothes. The air duct communicates with the clothes handling chamber inside the clothes handling drum to introduce airflow into the clothes handling chamber. In other words, this drying device can be used to dry clothes.

[0043] The location of the air duct outlet is not limited. For example, in some embodiments, the air duct outlet is located on the end cap, and the airflow from the air duct enters the garment processing chamber through the outlet on the end cap.

[0044] In some embodiments, the airflow within the garment processing chamber can be vented through a duct to the interior or exterior.

[0045] In other embodiments, both the inlet and outlet of the air duct are connected to the garment processing chamber to form a circulating air duct.

[0046] For example, the clothes dryer includes a front support disposed at the front end of the clothes handling drum for supporting the drum. An air duct inlet is disposed on the front support. That is, the airflow inside the clothes handling chamber enters the air duct through the inlet on the front support, undergoes condensation and dehumidification in the air duct, is then heated, and the heated airflow re-enters the clothes handling chamber from the outlet of the air duct, thus circulating in a cycle.

[0047] Please refer to the reference. Figures 1 to 3 The garment processing drum 100 includes a drum body 10, a functional layer component 20, and lifting ribs 30.

[0048] It should be noted that the cylinder body 10 has a clothing loading / unloading port 11 at one end along the axial direction. The clothing handling cylinder 100 also includes an end cap 14, which is located at the other end of the cylinder body 10 along the axial direction. That is, the clothing loading / unloading port 11 and the end cap 14 are located at opposite ends of the cylinder body 10 along the axial direction.

[0049] The cylinder body 10 and end cap 14 enclose a clothing processing cavity for holding clothing. The cylinder body 10 and end cap 14 constitute the main structure of the clothing processing cylinder 100. The cylinder body 10, as the main structural component of the clothing processing cylinder 100, must be made of a material that ensures the structural strength of the clothing processing cylinder 100. Exemplarily, in some embodiments, the cylinder body 10 is a metal cylinder body 10, that is, the material of the cylinder body 10 is metal, such as stainless steel.

[0050] In some embodiments, the tube body 10 is formed by winding a metal sheet, and the metal sheet is fastened at the joints of opposite ends along the winding direction, for example, by riveting or welding. Exemplarily, after the metal sheet is wound and fastened at the joints, one end of the tube body 10 is contracted inward to form a constricted opening. The constricted opening defines the garment insertion opening. Exemplarily, the tube body 10 is an airtight structure. That is, water, air, etc., cannot pass through the tube body 10; i.e., the tube body 10 does not have holes for water or air to pass through.

[0051] The functional layer assembly 20 covers the circumferential inner surface of the cylindrical body 10. The circumferential inner surface refers to the radially inner surface of the cylindrical body 10. That is, the shape of the functional layer assembly 20 is adapted to the shape of the cylindrical body 10, and is approximately cylindrical.

[0052] The phrase "covering the circumferential inner surface of the tube body 10" means that the functional layer component 20 covers the circumferential inner surface of the tube body 10, and the area of ​​the tube body 10 covered by the functional layer component 20 does not directly contact the clothing.

[0053] For example, the circumferential inner surface of the tube body 10 is a continuous smooth surface. That is, the tube body 10 has no patterns, i.e., no uneven structure. This facilitates close contact between the functional layer assembly 20 and the tube body 10, making the parts of the functional layer assembly 20 that come into contact with clothing relatively flat and less likely to abrade the clothing.

[0054] It is worth mentioning that in some embodiments, such as in a dryer, the clothes handling drum 100 does not need to come into contact with water. Therefore, the functional layer component 20 is basically not soaked in water. This reduces the requirements for the waterproof and corrosion-resistant properties of the material of the functional layer component 20, reduces the probability of damage to the noise reduction layer, and extends the service life of the functional layer component 20.

[0055] The lifting rib 30 is connected to the drum body 10. Specifically, the lifting rib 30 is located on the inner side of the drum body 10. There can be one or more lifting ribs 30. During the rotation of the garment processing drum 100, the lifting rib 30 carries the garments along with it. After the garments are lifted to a certain height, they fall back down under their own weight, thus loosening the garments.

[0056] For example, the lifting rib 30 presses the functional layer component 20 onto the circumferential inner surface of the cylinder body 10. In other words, while the lifting rib 30 is connected to the cylinder body 10, the functional layer component 20 is also connected to the cylinder body 10. In this way, the connection structure of the lifting rib 30 can be fully utilized, and there is no need to set an additional connection structure for the functional layer component 20 and the cylinder body 10, which facilitates assembly, improves assembly efficiency, and simplifies the connection structure between the functional layer component 20 and the cylinder body 10.

[0057] In addition, the lifting rib 30 has a relatively large area at one end facing the cylinder body 10. One end of the lifting rib 30 presses against the functional layer component 20, and the lifting rib 30 and the functional layer component 20 have a large contact area, which increases the force-bearing area of ​​the functional layer component 20, improves the connection reliability between the functional layer component 20 and the cylinder body 10, and makes the functional layer component 20 less prone to breakage.

[0058] Combination Figure 4 and Figure 6For example, the functional layer component 20 is constructed by winding a composite plate-like structure. When the functional layer component 20 is placed on the cylinder 10, the functional layer component 20 has a first end and a second end opposite each other in the circumferential direction, which is the circumferential direction of the cylinder 10 itself and is consistent with the winding direction. The first end and the second end are the two ends of the composite plate-like structure along the winding direction. The first end and the second end are spaced apart, making the thickness of each part of the functional layer component 20 more uniform, improving the compatibility of the functional layer component 20, and avoiding the impact on flatness caused by the overlap of the first end and the second end due to manufacturing tolerances.

[0059] Optionally, at least one of the lifting ribs 30 extends along the joint between the first end and the second end and presses the joint against the cylinder body 10. In this way, by pressing the lifting rib 30 directly against the cylinder body 10, it is possible to prevent the joint from lifting and to eliminate the need for connection operations at the joint, which helps to simplify the structure and further improve assembly efficiency.

[0060] To facilitate the assembly and disassembly of the functional layer assembly 20, in some embodiments, while the first end and the second end are spaced apart, at least one of the first end and the second end is provided with a handle 25. The handle 25 is configured to expose a portion of the circumferential inner surface of the cylinder body 10. The handle 25 may take the form of a through groove or opening that penetrates both surfaces of the functional layer assembly 20.

[0061] After removing the lifting rib 30, the user can obtain a point of leverage by using the handle 25 at the end of the composite plate structure to expose the part of the cylinder 10. The user can not only increase the contact area with the functional layer component 20 by manipulating the handle 25 and obtain a force application method that is easy to perform disassembly and assembly operations, but also contact the cylinder 10 through the handle 25 when removing the functional layer component 20, and further facilitate the separation of the functional layer component 20 from the cylinder 10 by lifting the functional layer component 20.

[0062] Because the handle 25 is located at the end and the first end is spaced apart from the second end, more of the cylinder body 10 is exposed, and it is easier for the user to operate the handle 25. During disassembly and assembly, the user has more operating space between the two ends, which facilitates the disassembly and assembly operations. Specifically, during disassembly, after operating the handle 25 to detach the end of the functional layer component 20 from the cylinder body 10, it is easy to lift the end to separate the rest of the functional layer component 20. During installation, the handle 25 can also be adjusted to facilitate the alignment of the two ends of the composite plate structure, improving assembly accuracy.

[0063] Combination Figure 2 and Figure 3In one embodiment, the handle 25 is located on the side of the functional layer assembly 20 near the garment loading / unloading port 11. That is, the handle 25 is located on the side of the functional layer assembly 20 away from the end cap 14, so that when the user disassembles or assembles the functional layer assembly 20, they do not need to probe too far into the bottom of the garment processing chamber. They can operate the handle 25 near the garment loading / unloading port 11, which further makes the disassembly and assembly operation convenient and quick.

[0064] For example, the tube body 10 includes a main body 12 and a front cover 13. The main body 12 is cylindrical and forms a circumferential inner surface of the tube body 10; the front cover 13 is connected to one end of the main body 12 and forms a clothing loading / unloading opening 11. The front cover 13 and the main body 12 can be connected by riveting or other means, and the end of the front cover 13 away from the main body 12 tapers inward to form a constricted opening. The constricted opening defines the clothing loading opening. The functional layer component 20 can fully cover the circumferential inner surface of the tube body 10 outside the constricted opening.

[0065] In this design, the handle 25 is spaced apart from the front cover 13 along the axial direction of the tub body 10. This ensures that the handle 25 is not obstructed by the front cover 13 when the user observes the inside of the tub through the clothing loading / unloading opening 11, making it easier for the user to locate and operate the handle 25. Furthermore, in some structures where the front cover 13 presses against the functional layer assembly 20, the handle 25, which is spaced apart from the front cover 13, can also reduce or prevent damage to the functional layer assembly 20 due to the torque between the front cover 13 and the assembly itself during disassembly.

[0066] Combination Figures 4 to 6 In one embodiment, the handle portion 25 is constructed as a handle groove, which opens towards the other end of the composite plate-like structure along the winding direction, and a portion of the circumferential inner surface of the cylinder body 10 is exposed in the handle groove. In this embodiment, the handle groove is a through groove penetrating both surfaces of the functional layer component 20. The handle groove is located at one end of the composite plate-like structure and opens towards the other end, thereby facilitating the user to insert the side of their hand into the handle groove. For example, the handle groove can be located at the first end and open towards the second end, or the handle groove can be located at the second end and open towards the first end. Moreover, the handle groove structure also makes the end of the composite plate-like structure non-straight, and the corners at the connection between the open opening of the handle groove and the end face of the composite plate-like structure make it easier for the user to exert force to separate the functional layer component 20 from the cylinder body 10.

[0067] For example, combined Figure 2 , Figure 3 as well as Figure 7The cylinder body 10 has at least two first connecting portions 15 corresponding to each lifting rib 30, and each lifting rib 30 has at least two second connecting portions 321. A handle groove is provided to avoid the first connecting portions 15 and the second connecting portions 321. At least one of the first connecting portions 15 and the second connecting portions 321 passes through the handle groove and is aligned and connected. Thus, the handle groove can not only be used by the user to assemble and disassemble the functional layer component 20, but also avoids obstruction of the connection between the lifting rib 30 and the cylinder body 10, facilitating the connection between the lifting rib 30 and the cylinder body 10.

[0068] Optionally, the first connecting part 15 protrudes towards the inner side of the cylinder body 10 and passes through the clearance hole. This facilitates the connection between the first connecting part 15 and the second connecting part 321 and also allows the outer side of the cylinder body 10 to be recessed. When using bolt connection, the bolt can be placed in the recessed area of ​​the first connecting part 15 on the outer side of the cylinder body 10 to ensure the overall flatness of the outer side of the cylinder body 10 and avoid the protruding bolt from interfering with the rotation of the cylinder body 10.

[0069] The sidewall of the handle groove is spaced apart from the first connecting part 15, so that the function of the handle groove for assembling and disassembling the functional layer component 20 is not affected, and the handle groove can be compatible with a larger size first connecting part 15, thereby improving the versatility of the functional layer component 20.

[0070] For example, the projection of the protruding part of the first connecting part 15 onto the inner surface of the cylinder 10 is roughly circular, and the projection of the side wall of the handle groove onto the inner surface of the cylinder 10 can also be roughly arc-shaped. When the centers of the first connecting part 15 and the handle groove are collinear, the radius of the handle groove can be greater than or equal to twice the radius of the first connecting part 15.

[0071] The projection of the sidewall of the handle groove onto the inner surface of the cylinder 10 is a superior arc with its center located within the handle groove. This increases the contact area and connection tightness between the handle groove and the user's hand or tool when the user operates the handle 25, making it easier to assemble and disassemble the functional layer component 20.

[0072] In this embodiment, the projection of the lifting rib 30 onto the circumferential inner surface of the cylinder 10 covers the projection of the handle groove onto the circumferential inner surface of the cylinder 10. This not only allows the lifting rib 30 to conceal the handle portion 25, improving aesthetics, but also protects the handle groove and the first and second ends of the functional layer component 20, preventing warping.

[0073] In one embodiment, the functional layer component 20 includes a plurality of handles 25, which are spaced apart along the axial direction of the cylindrical body 10. The plurality of handles 25 can provide the user with multiple leverage points located at the first and second ends, facilitating the user's manipulation of the ends of the composite plate structure and improving assembly and disassembly efficiency.

[0074] It should be noted that the multiple handles 25 can be used to avoid the connection between the first connecting part 15 and the second connecting part 321, or can be used in part to avoid the connection between the first connecting part 15 and the second connecting part 321, and some are only used for user operation.

[0075] Furthermore, for each lifting rib 30, the functional layer component 20 is provided with at least two positioning holes 24, and the lifting rib 30 is correspondingly provided with at least two positioning protrusions 331. The at least two positioning holes 24 are arranged at intervals along the extending direction of the lifting rib 30, and the at least two positioning protrusions 331 are correspondingly inserted into the at least two positioning holes 24. Through the positioning cooperation of the at least two positioning protrusions 331 and the at least two positioning holes 24, the positioning of the lifting rib 30 relative to the cylinder body 10 can be more accurate, which is conducive to further improving the alignment accuracy. At the same time, the connection between the functional layer component 20 and the lifting rib 30 is tighter, which facilitates the preliminary limiting of the lifting rib 30 before it is fixed, which is conducive to improving assembly efficiency.

[0076] Along the axial direction of the cylinder body 10, at least two positioning holes 24 and multiple handles 25 are alternately arranged, wherein at least two handles 25 are used to avoid the connection between the first connecting part 15 and the second connecting part 321. Thus, the multiple first connecting parts 15 and multiple second connecting parts 321 are arranged at intervals along the extending direction of the lifting rib 30, and multi-point fixing helps improve the connection reliability of the lifting rib 30. At the same time, the at least two positioning holes 24 and at least two positioning protrusions 331 are interspersed therein for positioning, which also improves the positioning accuracy and the stability of the lifting rib 30 during pre-positioning.

[0077] Of course, in one embodiment, at least one handle 25 can be provided in the middle of the composite plate structure along the winding direction to further increase the force points for the user when disassembling and assembling the functional layer component 20, making it easier for the user to disassemble and assemble the functional layer component 20 and improving the disassembly and assembly efficiency.

[0078] In this embodiment, the functional layer component 20 refers to a component that has at least one of the functions of moisturizing, sterilizing, and noise reduction. By setting the functional layer component 20 inside the drum body 10, the clothes drying drum can have functions such as moisturizing, sterilizing, and noise reduction, thereby improving the functionality of the drying equipment and enhancing the user experience. The following example illustrates the use of the functional layer component 20 for noise reduction.

[0079] Understandably, during the operation of a clothes dryer, zippers, buttons, and other fasteners on clothing will randomly strike the drum, producing sharp knocking sounds and causing significant noise pollution. To address this issue, in conjunction with... Figure 4 and Figure 8In some embodiments, the functional layer component 20 includes a first layered structure 23 and a second layered structure 21, with the second layered structure 21 located radially inside the first layered structure 23 along the garment processing tube 100. It should be noted that the first layered structure 23 and the second layered structure 21 are separated by layers along the thickness direction of the functional layer component 20. The first layered structure 23 is generally cylindrical around the circumference of the tube body 10, and the second layered structure 21 is also generally cylindrical around the circumference of the tube body 10. The first layered structure 23 and the second layered structure 21 are stacked.

[0080] The first layer structure 23 is in contact with the tube body 10. That is, the first layer structure 23 is the outermost layer of the functional layer component 20 in the radial direction. The second layer structure 21 serves as the external structure of the clothing handling tube 100. The second layer structure 21 is exposed in the clothing handling cavity, and the user can see the second layer structure 21 through the clothing loading and unloading port 11.

[0081] At least one of the first layered structure 23 and the second layered structure 21 serves as a functional structure; in this embodiment, the functional structure is a vibration damping and noise reduction structure. The vibration damping and noise reduction structure contains sound-insulating and noise-reducing materials to absorb vibration noise to a certain extent.

[0082] For example, the first layered structure 23 includes at least one of foamed plastic, foamed rubber, and foamed silicone. Foamed plastic is lightweight, sound-absorbing, vibration-damping, and corrosion-resistant, which helps to reduce the overall weight of the garment processing drum; foamed rubber and foamed silicone have good viscoelasticity and good damping effect in vibration reduction. The second layered structure 21 includes at least one of leather and a metal layer. The leather can be genuine leather or artificial leather. Leather can be easily processed into the required colors, patterns, etc., to achieve rich process designs. In addition, leather is relatively soft and can absorb loads and impacts and vibrations from foreign objects to a greater extent.

[0083] In the clothing processing drum 100 of this application embodiment, since the functional layer component 20 covers the circumferential inner surface of the drum body 10, the clothing does not directly contact the inner surface of the drum body 10, but rather contacts the functional layer component 20. When foreign objects such as buttons and zippers of the clothing strike the clothing processing drum 100, the functional layer component 20 can convert and absorb at least part of the vibration, thereby reducing the vibration amplitude transmitted to the drum body 10. This can suppress the generation of vibration noise to a certain extent and reduce the noise radiated outward by the clothing processing drum 100, thereby achieving a high noise reduction. In addition, the functional layer component 20 has a large coverage area on the drum body 10, which can play a large-scale noise reduction role.

[0084] The clothing processing tube 100 of this application embodiment has a layered design for the functional layer component 20. While meeting the requirements of noise reduction, it can also improve the industrial design flexibility of the second layer structure 21 and enhance the appearance of the functional layer component 20. In addition, users or operators can directly and visually observe the position, wear and tear of the functional layer component 20, which is convenient for timely maintenance and / or replacement.

[0085] For example, at least one of the first layered structure 23 and the second layered structure 21 serves as a support structure to generate a radially outward force on the cylinder 10, so that the functional layer assembly 20 can abut against the circumferential inner surface of the cylinder 10 under the action of the force. It should be noted that the support structure not only needs to have a certain structural strength, but also needs to have a certain toughness to apply a radially outward force to the cylinder 10.

[0086] The radial outward force exerted on the cylinder 10 refers to the fact that the supporting structure, under the action of its own material, exerts a certain radial outward force on the cylinder 10. This force is conducive to attaching the functional layer component 20 as a whole to the circumferential inner surface of the cylinder 10, and the functional layer component 20 as a whole is not easy to collapse or lift off the cylinder 10 under its own gravity.

[0087] In this embodiment, the force of the supporting structure helps to maintain the functional layer component 20 on the cylinder body 10 and helps to maintain the structural shape of the functional layer component 20. Even if the functional layer component 20 is only partially connected to the cylinder body 10, the entire functional layer component 20 can reliably rest on the circumferential inner surface of the cylinder body 10 and is not easy to collapse or lift off the cylinder body 10.

[0088] For example, the functional layer component 20 includes an adhesive layer 22 disposed between the first layered structure 23 and the second layered structure 21, and bonding the first layered structure 23 and the second layered structure 21 together. The adhesive layer 22 acts as a carrier to achieve a gapless connection between the first layered structure 23 and the second layered structure 21, making it less likely for the first layered structure 23 and the second layered structure 21 to delaminate.

[0089] Specifically, the adhesive layer 22 is a structure formed after the glue has cured. Specifically, during the manufacturing process, glue can be applied to one side of the first layered structure 23, or to one side of the second layered structure 21, or glue can be applied to one side of the first layered structure 23 and one layer of the second layered structure 21; the first layered structure 23 and the second layered structure 21 are then bonded together, and after the glue has cured, the first layered structure 23 and the second layered structure 21 are fixed together without gaps, and the adhesive layer 22 is formed after the glue has cured.

[0090] The specific type of adhesive is not limited, and the appropriate adhesive can be selected according to the different materials of the first layer structure 23 and the second layer structure 21.
