Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to a cooker. Background Art

[0002] Traditional cookware is mainly made of aluminum, which is generally non-magnetic and cannot be used on induction cookers. In order to make aluminum or other non-magnetic metal cookware suitable for induction cookers, a layer of metal sheet with good magnetic conductivity can be added to the bottom of the cookware.

[0003] However, during the process of compounding the metal sheet with the bottom of the cookware, the metal sheet is prone to unilateral displacement, so that the metal sheet compounded on the bottom of the cookware cannot completely wrap the aluminum substrate at the bottom of the cookware, resulting in the aluminum substrate being exposed, affecting the normal use and cleaning of the product. Utility Model Content

[0004] In view of this, the present application provides a cookware, so as to solve the problem in the prior art that the metal sheet is prone to unilateral displacement during the process of being compounded with the bottom of the pot body, so that the metal sheet compounded on the bottom of the cookware cannot completely wrap the aluminum substrate at the bottom of the cookware, resulting in the aluminum substrate being exposed, affecting the normal use and cleaning of the product.

[0005] The present application provides a cooker, comprising a bottom and a composite bottom sheet, the bottom being provided with a groove and a boss, the groove being annularly connected to the outer edge of the boss, the groove comprising a limiting surface, the composite bottom sheet being attached to the bottom, the composite bottom sheet comprising a main body and a connecting portion, the connecting portion being annularly connected to the main body, the main body being attached to the boss, the connecting portion being arranged in the groove, and the connecting portion abutting against the limiting surface along the radial direction of the cooker.

[0006] In the present application, the body of the bottom film is attached to the boss, and the connecting portion is arranged in the groove, so that the composite bottom film can completely cover the boss at the bottom of the pot, thereby providing protection for the boss. At the same time, the limiting surface of the groove can abut against the end of the connecting portion of the composite bottom film along the radial direction of the pot, thereby limiting the displacement of the composite bottom film along the radial direction of the pot during the composite process of the composite bottom film and the bottom, avoiding the composite bottom film from being offset relative to the bottom, thereby avoiding the base material at the edge of the boss from being exposed, so that during the heating and use of the pot, the edge of the boss can be sufficiently supported by the connecting portion of the composite bottom film, thereby improving the anti-deformation ability of the bottom of the pot, and will not be corroded by the outside world, which is convenient for users to clean and use normally.

[0007] In a possible design, the diameter of the bottom is D1, the outer diameter of the groove is D2, and D1 = D2.

[0008] In this solution, the diameter D1 of the bottom is the same as the outer diameter D2 of the groove, so that the space for setting the composite bottom sheet can be increased, so that the entire bottom of the pot can be provided with the composite bottom sheet, so that the composite bottom sheet can support the entire bottom, further improving the bottom's anti-deformation ability. At the same time, this structure can also increase the effective action area of ​​the composite bottom sheet, thereby forming a larger electromagnetic induction area, producing a better electromagnetic induction effect and a faster heating rate.

[0009] In a possible design, the groove also includes a bottom surface, which is perpendicular to the limiting surface, and the connecting portion includes a straight section and a transition section, the straight section is connected to the body through the transition section, and the straight section is in contact with the bottom surface.

[0010] In the present solution, the straight section is fitted with the bottom surface, that is, the straight section and the limiting surface are also arranged vertically. This structure can not only enhance the supporting effect of the straight section on the bottom along the height direction of the pot body, further enhance the deformation resistance of the bottom of the cookware, but also enhance the limiting effect of the limiting surface on the end surface of the straight section along the radial direction, thereby avoiding sliding of the end surface of the straight section along the limiting surface during the composite process of the composite bottom film and the bottom, thereby avoiding displacement of the composite bottom film relative to the bottom, reducing the difficulty of preparing the cookware, and improving the production efficiency of the cookware.

[0011] In a possible design, the boss includes a top surface, the groove also includes a side wall surface, two ends of the side wall surface are respectively connected to the bottom surface and the top surface, and the transition section is in contact with the side wall surface.

[0012] In this solution, the transition section fits with the side wall surface, thereby avoiding a gap between the composite bottom film and the bottom, further improving the supporting effect of the composite bottom film on the bottom, and further improving the deformation resistance of the bottom.

[0013] In a possible design, the side wall surface is an arc-shaped surface, and two ends of the arc-shaped surface are respectively tangent to the bottom surface and the top surface.

[0014] In this solution, the side wall surface is an arc-shaped surface, which can make the side wall surface and the bottom surface smoothly transition and connect. The transition section that fits the side wall surface is also an arc-shaped surface, so that the transition section and the straight section can also be smoothly transitioned and connected, avoiding dirt from being stuck between the transition section and the straight section, which is convenient for users to clean. The side wall surface is an arc-shaped surface, which can avoid the generation of edges and corners at the connection between the side wall surface and the bottom surface, and avoid the generation of edges and corners at the connection between the straight section and the transition section, so that during the process of compounding the backsheet and the bottom, the transition section of the connection part can slide along the side wall surface into the groove, making it easier for the transition section to fit with the side wall surface, ensuring the supporting effect of the transition section on the side wall surface.

[0015] In a possible design, the radius of the arc-shaped surface is R, 1mm≤R≤1.5mm.

[0016] In this solution, if the radius R of the arc surface is too large, for example, R>1.5mm, the thickness of the boss and the width of the bottom surface along the radial direction will increase, which will increase the thickness of the bottom and reduce the contact area between the bottom and the heating source, thereby reducing the heat conduction efficiency of the pot, resulting in reduced heating efficiency, which is inconvenient for users to cook; if the radius R of the arc surface is too small, for example, R<1mm, dirt is easily stuck between the transition section and the straight section, which is inconvenient for users to clean. Therefore, when the radius R of the arc surface satisfies 1mm≤R≤1.5mm, the thickness of the boss and the width of the bottom surface along the radial direction will not be too large, thereby avoiding the thickness of the bottom from being too thick, and ensuring that the bottom and the heating source can maintain sufficient contact area, thereby improving the heating efficiency of the pot, facilitating users to cook, and avoiding being stuck between the transition section and the straight section in the afternoon, which is convenient for users to clean and improves the user experience.

[0017] In a possible design, along the height direction of the cookware, the distance between the bottom surface and the top surface is H, 1.2 mm ≤ H ≤ 1.5 mm.

[0018] In this solution, if the distance H between the bottom surface and the top surface is too large, for example, H>1.5mm, the thickness of the bottom will increase, thereby reducing the heat conduction efficiency of the pot, resulting in reduced heating efficiency, which is inconvenient for users to cook; if the distance H between the bottom surface and the top surface is too small, for example, H<1.2mm, the bottom is too thin, making the bottom easily deformed by external forces, affecting the normal use of users. Therefore, when the distance H between the bottom surface and the top surface satisfies 1.2mm≤H≤1.5mm, the thickness of the bottom is moderate, which can ensure that the pot has a sufficiently fast heating efficiency while ensuring that the bottom of the pot has a higher deformation resistance, so that the bottom of the pot is not easily deformed by external forces, thereby ensuring the normal use of the user and improving the user's experience.

[0019] In a possible design, the height of the limiting surface is the same as the thickness of the complex film.

[0020] In this solution, the height of the limiting surface is the same as the thickness of the composite film, so that when the connecting part is located in the groove, the side surface of the connecting part facing away from the bottom can achieve a smooth transition connection with the side surface of the side part, avoiding the formation of steps between the connecting part and the side surface, thereby avoiding the edge of the connecting part from curling due to external interference, thereby improving the connection stability between the composite film and the bottom, and also facilitating cleaning by users, thereby improving user convenience.

[0021] In a possible design, the thickness of the composite film is d, 0.5 mm ≤ d ≤ 0.6 mm.

[0022] In this solution, if the thickness d of the composite bottom film is too thick, for example, d>0.6mm, the heat conduction efficiency of the pot will be reduced, and the materials used to make the composite bottom film will be increased, the manufacturing cost will be increased, and the overall weight of the pot will be increased, which will be inconvenient for users to use; if the thickness of the composite bottom film is too thin, for example, d<0.5mm, the composite bottom film is easy to deform and wear, which will easily reduce the supporting effect of the composite bottom film on the bottom, causing the bottom of the pot to be easily deformed when heated, affecting the normal use of the user. Therefore, when the thickness d of the composite bottom film satisfies 0.5mm≤d≤0.6mm, the thickness of the composite bottom film is moderate, which can ensure that the pot has a sufficiently fast heating efficiency while making the composite bottom film have increased support force and wear resistance, so that the composite bottom film can protect the bottom of the pot and support the bottom to prevent the bottom from being deformed when heated, thereby improving the anti-deformation ability of the pot and ensuring normal use by users.

[0023] In a possible design, the cooker also includes a side portion, which is arranged around the bottom and extends in a direction away from the bottom. The side portion includes a side surface, which is connected to the limiting surface, and the connecting portion forms a smooth connection with the side surface.

[0024] The connection portion forms a smooth connection with the side surface, thereby avoiding the generation of sharp corners at the connection between the side portion and the composite bottom film, thereby preventing the cookware from abrading the countertop or heating source, and also preventing the user from being scratched during the process of cleaning the cookware, thereby improving the safety of the cookware.

[0047] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0050] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0051] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0052] Traditional cookware is mainly made of aluminum, which is generally non-magnetic and cannot be used on induction cookers. In order to make aluminum or other non-magnetic metal cookware suitable for induction cookers, a layer of metal sheet with good magnetic conductivity can be compounded on the bottom of the cookware, and a boss is provided on the bottom of the cookware to facilitate contact between the bottom of the cookware and the platform or heating source.

[0053] Among them, when the metal sheet is compounded with the bottom of the pot, it is necessary to spot weld the metal sheet to the center of the bottom of the pot, then heat it at high temperature, and then pass through high-tonnage equipment to place the pot in the positioning ring of the double-mold mold to combine the metal sheet and the bottom of the pot into one.

[0054] However, during the process of compounding the metal sheet with the bottom of the pot, the metal sheet is prone to unilateral displacement, resulting in a unilateral displacement of 0.5mm to 1mm between the metal sheet and the boss at the bottom of the pot, so that the metal sheet compounded on the bottom of the pot cannot completely wrap the boss at the bottom of the pot, resulting in part of the aluminum substrate of the boss being exposed, which is easily corroded during cleaning, making it inconvenient to clean the pot. In addition, since the bottom of the pot and the metal sheet are made of different materials and have different expansion coefficients, the exposed aluminum substrate at the edge of the boss will be deformed when heated during the use of the pot, which can easily pull the entire bottom to deform outward or inward, thus affecting the normal use of the pot.

[0055] Based on this, the present application provides a cookware to prevent the aluminum substrate at the bottom of the cookware from being exposed, thereby facilitating the cleaning of the cookware and helping to improve the deformation resistance of the bottom of the cookware.

[0056] like Figure 1 and Figure 2As shown, the pot includes a bottom 1 and a side 3, the side 3 is arranged around the bottom 1 and extends in a direction away from the bottom 1, so that the side 3 and the bottom 1 together form a cavity capable of holding food. The bottom 1 and the side 3 can be formed by sheet stretching, and the bottom 1 and the side 3 are made of non-magnetic materials such as aluminum sheets, and the bottom 1 and the side 3 of the pot are an integrally formed structure.

[0057] The cookware also includes a composite bottom sheet 2, and the composite bottom sheet 2 is attached to the bottom 1. The composite bottom sheet 2 is made of magnetic conductive materials such as stainless steel, so that the cookware can be used for both open flame cookers and electromagnetic cookers, expanding the use range of the cookware and facilitating the use of users. The composite bottom sheet 2 can be a single layer or a composite of multiple layers, which is not limited here.

[0058] Among them, Figure 2 to Figure 4 As shown, the bottom 1 is provided with a groove 11 and a boss 12, the groove 11 is connected to the outer edge of the boss 12 in an annular manner, the groove 11 includes a limiting surface 111, the composite bottom film 2 includes a main body 21 and a connecting portion 22, the connecting portion 22 is connected to the main body 21 in an annular manner, the main body 21 is attached to the boss 12, the connecting portion 22 is arranged in the groove 11, and the connecting portion 22 abuts against the limiting surface 111 along the radial direction of the cookware.

[0059] In this embodiment, Figure 2 to Figure 4 As shown, the body 21 of the composite bottom sheet 2 is attached to the boss, and the connecting portion 22 is arranged in the groove 11, so that the composite bottom sheet 2 can completely cover the boss 12 of the bottom 1 of the pot, thereby providing protection for the boss 12. At the same time, the limiting surface 111 of the groove 11 can abut against the end of the connecting portion 22 of the composite bottom sheet 2 along the radial direction of the pot, so that during the composite process of the composite bottom sheet 2 and the bottom 1, the displacement of the composite bottom sheet 2 along the radial direction of the pot can be limited, and the composite bottom sheet 2 can be prevented from being offset relative to the bottom 1, thereby preventing the base material at the edge of the boss 12 from being exposed, so that during the heating and use of the pot, the edge of the boss 12 can be sufficiently supported by the connecting portion 22 of the composite bottom sheet 2, thereby improving the anti-deformation ability of the bottom 1 of the pot, and will not be corroded by the outside world, which is convenient for users to clean and use normally.

[0060] Among them, the groove 11 and the boss 12 can be directly formed on the bottom 1 when the aluminum sheet is formed, that is, the bottom 1 of the cookware is an integrated structure. It can be understood that the boss 12 can also be formed on the outside of the bottom 1 of the cookware by welding or other methods, which is not limited here.

[0061] In addition, the main body 21 and the connecting portion 22 of the composite film 2 may also be an integrally formed structure, so as to improve the production efficiency of the composite film 2 and save costs.

[0062] In addition, the boss 12 and the body 21 are planar structures, so that the cookware can be stably placed on a tabletop or above a heating source through the boss 12 and the body 21, thereby improving the stability of the cookware when it is placed.

[0063] In a specific embodiment, Figure 1 As shown, the diameter of the bottom 1 is D1, the outer diameter of the groove 11 is D2, and D1 = D2.

[0064] In this embodiment, Figure 1 As shown, the diameter D1 of the bottom 1 is the same as the outer diameter D2 of the groove 11, so that the installation space of the composite bottom sheet 2 can be increased, so that the entire bottom 1 of the cookware can be provided with the composite bottom sheet 2, so that the composite bottom sheet 2 can support the entire bottom 1, further improving the anti-deformation ability of the bottom 1. At the same time, this structure can also increase the effective action area of ​​the composite bottom sheet 2, thereby forming a larger electromagnetic induction area, producing a better electromagnetic induction effect and a faster heating rate.

[0065] In a specific embodiment, Figure 3 and Figure 4 As shown, the groove 11 also includes a bottom surface 112 , which is perpendicular to the limiting surface 111 , and the connecting portion 22 includes a straight section 221 and a transition section 222 , the straight section 221 is connected to the body 21 via the transition section 222 , and the straight section 221 fits the bottom surface 112 .

[0066] In this embodiment, Figure 3 and Figure 4 As shown, the straight section 221 is fitted with the bottom surface 112, that is, the straight section 221 and the limiting surface 111 are also vertically arranged. This structure can not only enhance the supporting effect of the straight section 221 on the bottom 1 along the height direction of the pot body, further enhance the deformation resistance of the bottom 1 of the cookware, but also enhance the limiting effect of the limiting surface 111 on the end face of the straight section 221 along the radial direction, thereby avoiding the end face of the straight section 221 from sliding along the limiting surface 111 during the composite process of the composite bottom film 2 and the bottom 1, thereby avoiding the composite bottom film 2 from deviating relative to the bottom 1, reducing the difficulty of preparing the cookware and improving the production efficiency of the cookware.

[0067] In a specific embodiment, Figure 3 and 4 As shown, the boss 12 includes a top surface 121 , and the groove 11 also includes a side wall surface 113 . Both ends of the side wall surface 113 are respectively connected to the bottom surface 112 and the top surface 121 , and the transition section 222 is in contact with the side wall surface 113 .

[0068] In this embodiment, Figure 4As shown, the transition section 222 fits with the side wall surface 113 , thereby avoiding a gap between the composite bottom film 2 and the bottom 1 , further improving the supporting effect of the composite bottom film 2 on the bottom 1 , and further improving the deformation resistance of the bottom 1 .

[0069] Furthermore, if Figure 3 and Figure 4 As shown, the side wall surface 113 is an arc-shaped surface, and two ends of the arc-shaped surface are tangent to the bottom surface 112 and the top surface 121 respectively.

[0070] In this embodiment, Figure 3 and Figure 4 As shown, the side wall surface 113 is an arc-shaped surface, which can make the side wall surface 113 and the bottom surface 112 smoothly transition and connect. The transition section 222 that fits the side wall surface 113 is also an arc-shaped surface, so that the transition section 222 and the straight section 221 can also be smoothly transitioned and connected, avoiding dirt from being stuck between the transition section 222 and the straight section 221, which is convenient for users to clean. The side wall surface 113 is an arc-shaped surface, which can avoid the generation of edges and corners at the connection between the side wall surface 113 and the bottom surface 112, and avoid the generation of edges and corners at the connection between the straight section 221 and the transition section 222, so that during the process of compounding the composite film 2 and the bottom 1, the transition section 222 of the connecting portion 22 can slide along the side wall surface 113 into the inside of the groove 11, so that the transition section 222 is easier to fit with the side wall surface 113, and the supporting effect of the transition section 222 on the side wall surface 113 is ensured.

[0071] In a specific embodiment, Figure 4 As shown, the radius of the arc surface is R, 1mm≤R≤1.5mm. For example, the radius R of the arc surface can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc. Of course, the radius R of the arc surface can also be other values ​​within the above range, which can be set according to actual needs and is not limited here.

[0072] In this embodiment, Figure 4 As shown, if the radius R of the curved surface is too large, for example, R>1.5mm, the thickness of the boss 12 and the radial width of the bottom surface 112 will increase, which will increase the thickness of the bottom 1 and reduce the contact area between the bottom 1 and the heating source, thereby reducing the thermal conductivity of the cookware, resulting in reduced heating efficiency and inconvenience for users to cook; if the radius R of the curved surface is too small, for example, R<1mm, dirt is easily stuck between the transition section 222 and the straight section 221, making it inconvenient for users to clean.

[0073] Therefore, when the radius R of the arc surface satisfies 1mm≤R≤1.5mm, the thickness of the boss 12 and the radial width of the bottom surface 112 will not be too large, thereby avoiding the thickness of the bottom 1 being too thick, and ensuring that the bottom 1 and the heating source can maintain sufficient contact area, thereby improving the heating efficiency of the cookware, facilitating users to cook, and avoiding getting stuck between the transition section 222 and the straight section 221 in the afternoon, facilitating users to clean, and improving the user experience.

[0074] In another embodiment, the side wall surface 113 may also be an inclined surface that is beveled relative to the bottom surface 112 , thereby further simplifying the structure of the groove 11 .

[0075] In a specific embodiment, Figure 3 and Figure 4 As shown, the side portion 3 includes a side surface 31 , the side surface 31 is connected to the limiting surface 111 , and the connecting portion 22 forms a smooth connection with the side surface 31 .

[0076] In this embodiment, Figure 3 and Figure 4 As shown, the connection portion 22 forms a smooth connection with the side surface 31, thereby avoiding the generation of sharp edges at the connection between the side portion 3 and the composite bottom film 2, thereby preventing the cookware from abrading the countertop or heating source, and preventing the user from being scratched during the process of cleaning the cookware, thereby improving the safety of the cookware.

[0077] In a specific embodiment, Figure 3 As shown, the height of the limiting surface 111 is the same as the thickness of the composite film 2 .

[0078] In this embodiment, Figure 3 As shown, the height of the limiting surface 111 is the same as the thickness of the composite film 2, so that when the connecting portion 22 is located in the groove 11, the side surface of the connecting portion 22 away from the bottom 1 can achieve a smooth transition connection with the side surface 31 of the side portion 3, avoiding the formation of a step between the connecting portion 22 and the side surface 31, thereby avoiding the edge of the connecting portion 22 from curling due to external interference, thereby improving the connection stability between the composite film 2 and the bottom 1, and also facilitating cleaning by users, thereby improving user convenience.

[0079] In a specific embodiment, Figure 4 As shown, the thickness of the composite film 2 is d, 0.5 mm ≤ d ≤ 0.6 mm. For example, the thickness d of the composite film 2 can be 0.5 mm, 0.52 mm, 0.54 mm, 0.56 mm, 0.58 mm, 0.6 mm, etc. Of course, the thickness d of the composite film 2 can also be other values ​​within the above range, which can be set according to actual needs and is not limited here.

[0080] In this embodiment, Figure 4 As shown, if the thickness d of the composite film 2 is too thick, for example d>0.6mm, the thermal conductivity of the cookware will be reduced, and the materials used to make the composite film 2 will be increased, thereby increasing the preparation cost and the overall weight of the cookware, making it inconvenient for users to use; if the thickness d of the composite film 2 is too thin, for example d<0.5mm, the composite film 2 will be easily deformed and worn, and the supporting effect of the composite film 2 on the bottom 1 will be easily reduced, causing the bottom 1 of the cookware to be easily deformed when heated, thereby affecting the normal use of the user.

[0081] Therefore, when the thickness d of the composite film 2 satisfies 0.5mm≤d≤0.6mm, the thickness of the composite film 2 is moderate, which can ensure that the cookware has a sufficiently fast heating efficiency while making the composite film 2 have increased supporting force and wear resistance, so that the composite film 2 can protect the bottom 1 of the cookware and support the bottom 1 to prevent the bottom 1 from being deformed by heat, thereby improving the anti-deformation ability of the cookware and ensuring normal use by users.

[0082] In a specific embodiment, Figure 4 As shown, along the height direction of the cookware, the distance between the bottom surface 112 and the top surface 121 is H, 1.2mm≤H≤1.5mm. For example, the distance H between the bottom surface 112 and the top surface 121 can be 1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc. Of course, the distance H between the bottom surface 112 and the top surface 121 can also be other values ​​within the above range, which can be set according to actual needs and is not limited here.

[0083] In this embodiment, Figure 3 and Figure 4 As shown, if the distance H between the bottom surface 112 and the top surface 121 is too large, for example, H>1.5mm, the thickness of the bottom 1 will increase, thereby reducing the thermal conductivity of the cookware, resulting in reduced heating efficiency, and making it inconvenient for users to cook; if the distance H between the bottom surface 112 and the top surface 121 is too small, for example, H<1.2mm, the bottom 1 is too thin, making the bottom 1 easily deformed by external force, affecting normal use by users.

[0084] Therefore, when the distance H between the bottom surface 112 and the top surface 121 satisfies 1.2mm≤H≤1.5mm, the thickness of the bottom 1 is moderate, which can ensure that the cookware has a sufficiently fast heating efficiency while ensuring that the bottom 1 of the cookware has a higher deformation resistance, making the bottom 1 of the cookware less likely to be deformed by external forces, thereby ensuring normal use by users and improving the user experience.

[0085] In this specification, the same or similar parts between the various embodiments can be referred to each other. In particular, for the device embodiment and the terminal embodiment, since they are basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the description in the method embodiment.

[0086] The above is only a specific implementation of the embodiment of the present application, but the protection scope of the embodiment of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed in the embodiment of the present application should be included in the protection scope of the embodiment of the present application. Therefore, the protection scope of the embodiment of the present application should be based on the protection scope of the claims.
