[0001] The utility model relates to cooking equipment technical field, specifically to a kind of heating device and cooking equipment. BACKGROUND

[0002] In related art, the metal winding of heating device is usually inserted in the heat insulation layer, which is arranged in the plastic support frame. When the metal winding heats and cools down, the metal winding expands and rebounds, which causes the deformation of the heat insulation layer, and the periphery of the heat insulation layer pops out of the plastic support frame, affecting the reliability of the heating device. SUMMARY

[0007] The heating device provided by the utility model comprises a support assembly, a heat insulation assembly and a heating assembly, the heating assembly is arranged on the heat insulation assembly, the heat insulation assembly is arranged on the support assembly, and the influence of the heating assembly on the support assembly is reduced through the heat insulation assembly, so that the heating device can be used normally.

[0008] The support assembly comprises a support body and an anti-warping structure, the support body has a mounting slot, the heat insulation assembly is embedded in the mounting slot, the heat insulation assembly is protected by the support body, the anti-warping structure is arranged on the support body, and the anti-warping structure is connected to the heat insulation assembly to restrict the heat insulation assembly in the mounting slot, reduce the possibility of warping of the heat insulation assembly, and improve the reliability of the heating device.

[0009] In addition, the heating device according to the above technical solution provided by the utility model can also have the following additional technical features:

[0010] In some embodiments, at least part of the heating assembly can be disc-shaped, the heating assembly covers part of the heat insulation assembly, and the anti-warping structure is connected to the heat insulation assembly outside the heating assembly.

[0011] In this embodiment, at least a portion of the heating component is disc-shaped, thereby enabling electromagnetic heating and infrared heating. The heating component covers a portion of the heat insulation component. Since the heat insulation component is typically warped at the edges, meaning that the heat insulation component located outside the heating component is more prone to warping, the anti-warping structure is connected to the heat insulation component located outside the heating component, which can maximize the restriction of the anti-warping structure on the heat insulation component.

[0012] In some embodiments, the insulation component may optionally have a receiving groove in which the heating component is located.

[0013] In this embodiment, the heat insulation component has a receiving groove, and the heating component is located in the receiving groove, so that the heat insulation component can insulate the heating component in multiple directions and reduce the impact of the heating component on external devices.

[0014] In some embodiments, the anti-warping structure is optionally used to bond the first peripheral sidewall of the mounting groove and the second peripheral sidewall of the thermal insulation component.

[0015] In this embodiment, the anti-warping structure is bonded between the first peripheral sidewall of the mounting groove and the second peripheral sidewall of the thermal insulation component, thereby increasing the connection force between the peripheral side of the thermal insulation component and the support assembly, and thus reducing the possibility of warping of the thermal insulation component.

[0016] In some embodiments, the anti-warping structure is optionally pressed onto the thermal insulation component.

[0017] In this embodiment, the anti-warping structure presses against the thermal insulation component, thereby confining the thermal insulation component within the mounting groove and reducing the possibility of warping of the thermal insulation component.

[0018] In some embodiments, the thermal insulation component may optionally have a periphery with an anti-warping structure pressed against the periphery.

[0019] In this embodiment, an edge is provided on the periphery of the heat insulation component, and the anti-warping structure presses on the edge, so that a part of the heat insulation component protrudes from the support body, thereby reducing the impact of the heating component on the support component and improving the reliability of the heating device.

[0020] In some embodiments, the anti-warping structure and the support body may be an integral structure; or the anti-warping structure may be fixed to the support body by a connector; or the anti-warping structure may be fixed to the support body by a snap-fit; or the anti-warping structure may be embedded in the support body.

[0021] In this embodiment, the anti-warping structure and the support body can be an integral structure, thereby increasing the connection strength between the anti-warping structure and the support body and improving the limiting effect of the anti-warping structure on the thermal insulation component.

[0022] Alternatively, the anti-warping structure can be fixed to the support body through connectors, which facilitates the installation of the anti-warping structure and the support body and ensures the connection strength between the anti-warping structure and the support body.

[0023] Alternatively, the anti-warping structure can be snapped onto the bracket body, which facilitates the installation of the anti-warping structure and the bracket body and ensures the connection strength between the anti-warping structure and the bracket body.

[0024] Alternatively, the anti-warping structure can be embedded into the bracket body through injection molding or other methods, thereby facilitating the installation of the anti-warping structure and the bracket body and ensuring the connection strength between the anti-warping structure and the bracket body.

[0025] In some embodiments, the thermal insulation component may optionally include: a first thermal insulation layer, a heating component disposed on the first thermal insulation layer, and an anti-warping structure pressed on the first thermal insulation layer; and a second thermal insulation layer disposed on the first thermal insulation layer and covering the anti-warping structure.

[0026] In this embodiment, the heat insulation component includes a first heat insulation layer and a second heat insulation layer. The heating component is disposed on the first heat insulation layer, and the anti-warping structure is pressed on the first heat insulation layer. Then, the second heat insulation layer is disposed on the first heat insulation layer and covers the anti-warping structure. This reduces the thickness of the heat insulation component, thereby reducing the force of deformation of the heat insulation component and improving the ability of the anti-warping structure to restrict the heat insulation component, thus reducing the possibility of warping of the heat insulation component.

[0027] In some embodiments, the support body may optionally be provided with a first rib, which is used to fix the second heat insulation layer.

[0028] In this embodiment, a first rib is provided on the main body of the support. The first rib can fix the second heat insulation layer, so that the second heat insulation layer can also limit the warping of the first heat insulation layer, thereby further reducing the possibility of warping of the heat insulation component.

[0029] In some embodiments, the anti-warping structure is optionally located at the bottom of the mounting groove and is embedded in the thermal insulation component.

[0030] In this embodiment, the anti-warping structure is disposed at the bottom of the mounting groove and is embedded in the heat insulation component, thereby limiting the heat insulation component through friction and reducing the possibility of warping of the heat insulation component.

[0031] In some embodiments, the anti-warping structure may be ring-shaped; or the number of anti-warping structures may be at least two, with the at least two anti-warping structures arranged on the support body in the shape of the thermal insulation component.

[0032] In this embodiment, the anti-warping structure is ring-shaped, thereby restricting the warping of the thermal insulation component from all directions.

[0033] Alternatively, the number of anti-warping structures is at least two, and the at least two anti-warping structures are arranged on the support body according to the shape of the thermal insulation component, thereby restricting the warping of the thermal insulation component at multiple locations, thereby reducing the possibility of warping of the thermal insulation component, saving material input, and reducing production costs.

[0034] In some embodiments, optionally, there is a gap between at least part of the insulation component and the bottom of the mounting groove.

[0035] In this embodiment, at least a portion of the insulation components and the bottom of the mounting groove have a gap, which facilitates the addition of other insulation materials such as insulation cotton, thereby improving the insulation effect on the heating components.

[0036] According to a second aspect of the present invention, a cooking device is provided, comprising: a heating device as described in the first aspect embodiment.

[0037] The cooking device proposed in this utility model includes the heating device as described in the first aspect embodiment, and therefore has all the beneficial effects of the heating device as described in the first aspect embodiment, which will not be described in detail here.

Detailed Implementation

[0059] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0060] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0061] The following reference Figures 1 to 17 This invention describes a heating device 100 and a cooking apparatus provided according to some embodiments of the present invention.

[0062] like Figure 1 , Figure 2 , Figure 16 and Figure 17 As shown, according to a first aspect of the present invention, the present invention provides a heating device 100, which includes a support assembly 110, a heat insulation assembly 130, and a heating assembly 150. The heating assembly 150 is disposed on the heat insulation assembly 130, and the heat insulation assembly 130 is disposed on the support assembly 110. The support assembly 110 includes a support body 112 and an anti-warping structure 122 disposed on the support body 112. The support body 112 has a mounting groove 114, and the heat insulation assembly 130 is disposed in the mounting groove 114. The anti-warping structure 122 is connected to the heat insulation assembly 130, thereby reducing the possibility of warping of the heat insulation assembly 130.

[0063] The heating device 100 provided by this utility model includes a support assembly 110, a heat insulation assembly 130 and a heating assembly 150. The heating assembly 150 is disposed on the heat insulation assembly 130, and the heat insulation assembly 130 is disposed on the support assembly 110. The heat insulation assembly 130 reduces the impact of the heating assembly 150 on the support assembly 110, so that the heating device 100 can be used normally.

[0064] The bracket assembly 110 includes a bracket body 112 and an anti-warping structure 122. The bracket body 112 has a mounting groove 114, and the heat insulation component 130 is embedded in the mounting groove 114. The bracket body 112 protects the heat insulation component 130. The anti-warping structure 122 is disposed on the bracket body 112 and is connected to the heat insulation component 130, confining the heat insulation component 130 within the mounting groove 114, reducing the possibility of warping of the heat insulation component 130, and improving the reliability of the heating device 100.

[0065] Specifically, the heating component 150 typically includes a coil. The coil winding material has a large coefficient of thermal expansion, thickness, and length, resulting in significant deformation forces. The heat insulation component 130 often uses silica, a brittle material prone to deformation and breakage, affecting structural integrity and thus the heat insulation effect of the heat insulation component 130. Furthermore, the heating component 150 is susceptible to deformation during hot and cold cycles. The heating component 150 provided by this invention, by incorporating an anti-warping structure 122, reduces the likelihood of the heat insulation component 130 popping out of the support component 110 due to deformation, ensuring the reliability of the heating component 150. Figure 1 As shown, the spirally wound metal winding in the heating assembly 150 is fixed on the heat insulation assembly 130 and placed inside the bracket assembly 110.

[0066] The heating component 150 has both electromagnetic heating and infrared heating functions. That is, the heating component 150 can heat via electromagnetic heating, infrared heating, or both simultaneously. The support body 112 can be made of plastic to reduce costs and prevent overheating due to electromagnetic interference.

[0067] like Figure 1 , Figure 16 and Figure 17 As shown, in some embodiments, optionally, at least a portion of the heating assembly 150 is disc-shaped, the heating assembly 150 covers a portion of the heat insulation assembly 130, and the anti-warping structure 122 is connected to the heat insulation assembly 130 located outside the heating assembly 150.

[0068] In this embodiment, at least a portion of the heating component 150 is disc-shaped, thereby enabling electromagnetic heating and infrared heating. The heating component 150 covers a portion of the heat insulation component 130. Since the heat insulation component 130 is typically warped at the edges, that is, the heat insulation component 130 located outside the heating component 150 is more prone to warping, the anti-warping structure 122 is connected to the heat insulation component 130 located outside the heating component 150, which can maximize the restriction of the heat insulation component 130 by the anti-warping structure 122.

[0069] like Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 11 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, the thermal insulation component 130 has a receiving groove 132, and the heating component 150 is located within the receiving groove 132.

[0070] In this embodiment, the heat insulation component 130 has a receiving groove 132, and the heating component 150 is located in the receiving groove 132, so that the heat insulation component 130 can insulate the heating component 150 in multiple directions and reduce the impact of the heating component 150 on external devices.

[0071] The heating assembly 150 has a coil disc and an annular receiving groove 132, with the coil disc and the receiving groove 132 arranged to cooperate with each other.

[0072] like Figure 2 and Figure 3 As shown, in some embodiments, the anti-warping structure 122 may optionally be an adhesive, which is used to bond the first peripheral sidewall 120 of the mounting groove 114 and the second peripheral sidewall 134 of the thermal insulation component 130.

[0073] In this embodiment, the anti-warping structure 122 is an adhesive component, which is bonded between the first peripheral sidewall 120 of the mounting groove 114 and the second peripheral sidewall 134 of the thermal insulation component 130, thereby increasing the connection force between the peripheral side of the thermal insulation component 130 and the support assembly 110, thereby reducing the possibility of the thermal insulation component 130 warping.

[0074] Among them, the anti-warping structure 122 can be a heat-resistant adhesive, that is, the anti-warping structure 122 can maintain its bonding strength at high temperatures. The high temperature can be above 100 degrees Celsius. The specific temperature value can be determined according to the heating effect of the heating component 150 and the heat insulation effect of the heat insulation component 130. For example, the anti-warping structure 122 can withstand high temperatures of 1000 degrees Celsius, 800 degrees Celsius, 600 degrees Celsius, 500 degrees Celsius, 300 degrees Celsius, 200 degrees Celsius or 100 degrees Celsius.

[0075] like Figure 2 and Figure 3 As shown, an anti-warping structure 122 is provided between the heat insulation component 130 and the bracket component 110. The anti-warping structure 122 is a heat-resistant adhesive, which can connect the heat insulation component 130 and the bracket component 110 together. The adhesive force pulls the deformation direction of the heat insulation component 130 in the opposite direction, so that the heat insulation component 130 does not deform after the heating component 150 heats up.

[0076] The deformation force of the heat insulation component 130 is F1, and the force exerted on the heat insulation component 130 by the support component 110 and the anti-warping structure 122 is F2, thereby preventing the heat insulation component 130 from warping.

[0077] like Figures 4 to 12 As shown, in some embodiments, the anti-warping structure 122 may optionally be a pressure plate, which presses against the thermal insulation component 130.

[0078] In this embodiment, the anti-warping structure 122 is a pressure plate that presses against the heat insulation component 130, thereby confining the heat insulation component 130 within the mounting groove 114 and reducing the possibility of warping of the heat insulation component 130.

[0079] The anti-warping structure 122 can be annular and pressed against the edge of the thermal insulation component 130, or there can be at least two anti-warping structures 122, each pressed against the edge of the thermal insulation component 130.

[0080] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 12 As shown, in some embodiments, optionally, the thermal insulation component 130 has a periphery with an edge 136, and the anti-warping structure 122 presses against the edge 136.

[0081] In this embodiment, an edge 136 is provided on the periphery of the heat insulation component 130, and the anti-warping structure 122 presses on the edge 136, so that a part of the heat insulation component 130 protrudes from the support body 112, thereby reducing the impact of the heating component 150 on the support component 110 and improving the reliability of the heating device 100.

[0082] like Figures 4 to 6 As shown, in some embodiments, the anti-warping structure 122 and the support body 112 are optionally an integral structure.

[0083] In this embodiment, the anti-warping structure 122 and the support body 112 can be an integral structure, thereby increasing the connection strength between the anti-warping structure 122 and the support body 112 and improving the limiting effect of the anti-warping structure 122 on the heat insulation component 130.

[0084] like Figure 5 As shown, during processing, a protrusion G is pre-reserved on the support body 112, and then the protrusion G is deformed to form a shape as shown. Figure 6 The anti-warping structure 122 shown.

[0085] Specifically, such as Figure 5 As shown, the support body 112 is made of thermoplastic and has heat-pressable protrusions G. The edges of the heat insulation component 130 are partially or entirely lower than the protrusions G. The protrusions G are melted and deformed using a hot press knife to form an anti-warping structure 122. (As shown...) Figure 6As shown, the anti-warping structure 122 holds the heat insulation component 130 in place and applies a force in the opposite direction to the deformation of the heat insulation component 130, thus achieving the effect that the heat insulation component 130 does not deform after being heated by the heating component 150. The deformation force of the heat insulation component 130 is F1, and the force generated by the anti-warping structure 122 on the heat insulation component 130 is F2, thereby preventing the heat insulation component 130 from warping.

[0086] like Figure 7 As shown, in some embodiments, the anti-warping structure 122 is optionally fixed to the bracket body 112 by a connector 160.

[0087] In this embodiment, the anti-warping structure 122 can be fixed to the bracket body 112 via the connector 160, thereby facilitating the installation of the anti-warping structure 122 and the bracket body 112 and ensuring the connection strength between the anti-warping structure 122 and the bracket body 112. The deformation force of the heat insulation component 130 is F1, and the force generated by the heat insulation component 130 of the anti-warping structure 122 is F2, thus preventing the heat insulation component 130 from warping.

[0088] The connector 160 can be a screw or a rivet.

[0089] like Figures 8 to 10 As shown, in some embodiments, the anti-warping structure 122 is optionally fixed to the bracket body 112 by a snap fastener 124.

[0090] In this embodiment, the anti-warping structure 122 can be snapped onto the bracket body 112 by the snap fastener 124, thereby facilitating the installation of the anti-warping structure 122 and the bracket body 112 and ensuring the connection strength between the anti-warping structure 122 and the bracket body 112.

[0091] like Figure 8 and Figure 9 As shown, the edge of the thermal insulation component 130 is provided with one or more edge segments 136 for placing the anti-warping structure 122. The anti-warping structure 122 is fastened to the support body 112 by a buckle 124, applying a force to the thermal insulation component 130 in the opposite direction to its deformation, tightening the thermal insulation layer to prevent or reduce deformation. The anti-warping structure 122 clamps downward to the support body 112, restraining the deformation of the thermal insulation component 130, thus preventing the thermal insulation component 130 from deforming. The deformation force of the thermal insulation component 130 is F1, and the force generated by the anti-warping structure 122 on the thermal insulation component 130 is F2, thereby preventing the thermal insulation component 130 from warping.

[0092] like Figure 10 As shown, the anti-warping structure 122 has a buckle 124, and the bracket body 112 has a slot, into which the buckle 124 can be snapped.

[0093] like Figure 11 andFigure 12 As shown, in some embodiments, the anti-warping structure 122 is optionally embedded in the support body 112.

[0094] In this embodiment, the anti-warping structure 122 can be embedded into the bracket body 112 by injection molding or other means, thereby facilitating the installation of the anti-warping structure 122 and the bracket body 112 and ensuring the connection strength between the anti-warping structure 122 and the bracket body 112.

[0095] like Figure 11 and Figure 12 As shown, an anti-warping structure 122 is provided on the support body 112. The anti-warping structure 122 presses against the heat insulation component 130. The anti-warping structure 122 can be inserted into the support body 112 from the side or vertically and then bent to press against the heat insulation component 130. The deformation force of the heat insulation component 130 is F1, and the force generated by the anti-warping structure 122 on the heat insulation component 130 is F2, thereby preventing the heat insulation component 130 from warping.

[0096] like Figure 11 and Figure 12 As shown, in some embodiments, optionally, the heat insulation component 130 includes a first heat insulation layer 138 and a second heat insulation layer 140, the heating component 150 is disposed on the first heat insulation layer 138, the anti-warping structure 122 is pressed on the first heat insulation layer 138, the second heat insulation layer 140 is disposed on the first heat insulation layer 138 and covers the anti-warping structure 122, and the second heat insulation layer 140 is located on the outside of the heating component 150.

[0097] In this embodiment, the heat insulation component 130 includes a first heat insulation layer 138 and a second heat insulation layer 140. The heating component 150 is disposed on the first heat insulation layer 138. The anti-warping structure 122 is pressed on the first heat insulation layer 138. Then, the second heat insulation layer 140 is disposed on the first heat insulation layer 138 and covers the anti-warping structure 122. By reducing the thickness of the heat insulation component 130, the deformation force of the heat insulation component 130 is reduced, thereby improving the restraining ability of the anti-warping structure 122 on the heat insulation component 130 and reducing the possibility of the heat insulation component 130 warping.

[0098] like Figure 11 and Figure 12 As shown, the heat insulation component 130 can be designed in layers. That is, the heat insulation component 130 includes a bottom first heat insulation layer 138 and a top second heat insulation layer 140. A non-magnetic metal anti-warping structure 122 is added to the side of the bracket body 112. The anti-warping structure 122 presses the first heat insulation layer 138. The metal sheet can be inserted into the bracket body 112 from the side or vertically and then bent to press the first heat insulation layer 138.

[0099] Of course, in other embodiments of this utility model, the heating component 150 may also be fixed on the second heat insulation layer 140.

[0100] like Figure 11 and Figure 12 As shown, in some embodiments, optionally, a first rib 118 is provided on the bracket body 112, the first rib 118 being used to fix the second heat insulation layer 140.

[0101] In this embodiment, a first rib 118 is provided on the support body 112. The first rib 118 can fix the second heat insulation layer 140, so that the second heat insulation layer 140 can also limit the warping of the first heat insulation layer 138, thereby further reducing the possibility of warping of the heat insulation component 130.

[0102] like Figure 11 and Figure 12 As shown, the main body 112 of the bracket is also provided with a first protruding rib 118, which clamps the second heat insulation layer 140 with an interference fit. The material of the second heat insulation layer 140 is harder and more wear-resistant, making it suitable for interference clamping. This also serves to prevent the first heat insulation layer 138 from deforming.

[0103] Optionally, the first heat insulation layer 138 may be made of a heat insulation material with added ceramic fibers, and / or the second heat insulation layer 140 may be made of a heat insulation material with added ceramic fibers, which has good wear resistance, but the first rib 118 or heating component 150 cannot pierce the second heat insulation layer 140, and the first rib 118 or heating component 150 can be fixed on the second heat insulation layer 140.

[0104] like Figures 13 to 15 As shown, in some embodiments, the anti-warping structure 122 is optionally a fixing nail, the anti-warping structure 122 is located at the bottom 116 of the mounting groove 114, and the anti-warping structure 122 is embedded in the heat insulation component 130.

[0105] In this embodiment, the anti-warping structure 122 is a fixing nail. The anti-warping structure 122 is disposed at the bottom 116 of the mounting groove 114. The anti-warping structure 122 is embedded in the heat insulation component 130, thereby limiting the heat insulation component 130 through friction and reducing the possibility of the heat insulation component 130 warping.

[0106] The anti-warping structure 122 can be made of metal or plastic, etc.

[0107] Optionally, the anti-warping structure 122 gradually increases in cross-sectional area from the side away from the support body 112 to the side connected to the support body 112. The anti-warping structure 122 can be a pyramidal or triangular sheet-like structure, etc.

[0108] like Figure 13 andFigure 14 As shown, a ring of anti-warping structure 122 is provided at the bottom 116 of the mounting groove 114 of the bracket body 112. The anti-warping structure 122 can be installed on the bracket body 112 by riveting or in-mold injection molding. By puncturing the side of the heat insulation component 130 away from the heating component 150, a frictional force opposite to the deformation of the heat insulation component 130 is provided to tighten the heat insulation layer and prevent it from deforming. The deformation force of the heat insulation component 130 is F1, and the force generated by the anti-warping structure 122 on the heat insulation component 130 is F2, thereby preventing the heat insulation component 130 from warping.

[0109] like Figure 15 As shown, a ring of anti-warping structure 122 can be provided at the bottom 116 of the mounting groove 114 of the bracket body 112.

[0110] like Figure 16 As shown, in some embodiments, the anti-warping structure 122 is optionally annular.

[0111] In this embodiment, the anti-warping structure 122 is annular, thereby restricting the warping of the thermal insulation component 130 in all directions.

[0112] like Figure 17 As shown, in some embodiments, optionally, the number of anti-warping structures 122 is at least two, and at least two anti-warping structures 122 are arranged on the support body 112 in the shape of the thermal insulation component 130.

[0113] In this embodiment, there are at least two anti-warping structures 122. The at least two anti-warping structures 122 are arranged on the support body 112 according to the shape of the heat insulation component 130, thereby limiting the warping of the heat insulation component 130 at multiple locations. This reduces the possibility of warping of the heat insulation component 130, saves material input, and reduces production costs.

[0114] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, there is a gap between at least a portion of the thermal insulation component 130 and the bottom 116 of the mounting groove 114.

[0115] In this embodiment, at least a portion of the heat insulation component 130 and the bottom 116 of the mounting groove 114 have a gap, which facilitates the addition of other heat insulation materials such as heat insulation cotton, thereby improving the heat insulation effect on the heating component 150.

[0116] like Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, at least a portion of the thermal insulation component 130 protrudes from the support component 110.

[0117] In this embodiment, at least a portion of the heat insulation component 130 protrudes from the support component 110, thereby reducing the impact of the heat from the heating component 150 on the support component 110, and facilitating the addition of other heat insulation materials to improve the heat insulation effect on the heating component 150.

[0118] Specifically, the heating device 100 provided by this utility model has a heating component 150 disposed on a heat insulation component 130, and the heat insulation component 130 may be provided with a heating component 150 formed by a metal winding. The winding of the heating component 150 contains at least one continuously wound metal material, which appears as a wavy spiral in top view, and the cross-section of the metal material is flat.

[0119] Among them, a heat-resistant adhesive is provided between the heat insulation component 130 and the bracket component 110; or part or all of the edge 136 of the heat insulation component 130 is lower than the bracket body 112, and a protrusion G is provided on the bracket body 112. The protrusion G can be deformed by hot pressing to form an anti-warping structure 122; or, fixing nails can be planted in the bottom 116 of the mounting groove 114 of the bracket body 112 or a ring of fixing nails can be injected in the mold; the edge of the heat insulation component 130 is provided with a ring or multiple edge segments 136 for placing the anti-warping structure 122, and the anti-warping structure 122 and the bracket body 112 are fastened by a buckle 124.

[0120] The force that causes the thermal insulation component 130 to deform is F1. By applying a force F2 in the opposite direction of its deformation to the thermal insulation component 130, the thermal insulation component 130 is tightened so that the displacement of the deformation is slowed down or there is no deformation.

[0121] Specifically, the material of the winding of the heating component 150 is a metal material that can withstand temperatures above 600°C; the heat insulation component 130 can place and fix the winding, that is, the winding can be pierced and fixed thereon; the material of the heat insulation component 130 has a certain degree of toughness.
