[0007] A cooking appliance provided by the present application includes an appliance body, a heating member, a fan blade and a driving member.

[0008] A cooking cavity is provided inside the appliance body, and the appliance body includes an electromagnetic member, and the electromagnetic member is used to drive the heating member to generate heat. The food ingredients are placed in the cooking cavity. When the cooking appliance works, the electromagnetic member is powered on to generate a magnetic field, and the magnetic field acts on the heating member. The heating member generates heat to generate heat. The heating member generates heat to heat the air to form hot air, and the hot air is used to cook the food ingredients in the cooking cavity.

[0009] Wherein, the heating member is disposed below the electromagnetic member, and a first flow channel is enclosed by the heating member and the inner wall of the electromagnetic member, the first flow channel communicates with the cooking cavity, the heating member is provided with a second flow channel, and the second flow channel communicates with the cooking cavity and the first flow channel. The fan blade is located at the second flow channel. The driving member drives the fan blade to rotate, and the fan blade rotates to disturb the air flow, so as to drain air from the cooking cavity to the second flow channel and return it to the cooking cavity through the first flow channel. When the air flow passes through the heating member, it can take away the heat at the heating member to achieve the purpose of circulating hot air in the cooking cavity.

[0010] The appliance body, the fan blades and the heating element cooperate to define the flow path of the hot air in the cooking cavity, so that the airflow in the cooking cavity can flow to the heating element, and then flow back into the cooking cavity after passing through the second flow channel and the first flow channel. That is, it is possible to achieve that the hot air can flow from one side of the food placed in the cooking cavity to the other side of the food, so as to fully heat and bake the food, ensure the temperature balance of different sides of the food, ensure that the food is evenly heated, and help improve the cooking taste of the food.

[0011] It can be understood that, since the inner walls of the heating element and the electromagnetic element enclose the first flow channel, the airflow passing through the first flow channel can effectively take away the heat from the heating element, so that the hot air can circulate in the cooking cavity.

[0012] The cooking utensil described above in this application may also have the following additional technical features:

[0013] In some embodiments, optionally, the first flow channel is arranged around the second flow channel.

[0014] In this embodiment, the matching structure of the heating element and the appliance body is further defined so that the first flow channel is arranged around the second flow channel. Specifically, the outer edge of the heating element and the electromagnetic element enclose an outlet of the first flow channel, that is, the airflow in the first flow channel flows back into the cooking cavity through the outlet.

[0015] The positional relationship between the first flow channel and the second flow channel is defined so that the first flow channel is arranged around the second flow channel. For example, the first flow channel is an annular flow channel, and the annular flow channel is arranged around the second flow channel. For example, the first flow channel is an arcuate flow channel, and the arcuate flow channel is arranged around the second flow channel.

[0016] This arrangement allows the airflow to enter the first flow channel from the second flow channel, and then radiate to the surroundings, taking away the heat on the heating element, and after fully exchanging heat with the heating element, radiate along the heating element from the surroundings of the heating element and flow to the cooking cavity. This arrangement allows hot air to be sent to the cooking cavity from multiple directions and multiple angles, so that the hot air can flow to the food from multiple directions and multiple angles to fully heat and bake the food, and ensure the cooking taste of the food.

[0017] In some embodiments, optionally, a second flow channel is provided in the middle of the heating element.

[0018] In this embodiment, the structure of the heating element is further defined such that a second flow channel is provided in the middle of the heating element. In this way, when the driving element drives the fan to rotate, the air flow in the cooking cavity flows to the second flow channel in the middle of the heating element, then to the first flow channel, and then diverges around, taking away the heat on the heating element, fully exchanging heat with the heating element, and then dissipating along the heating element from the periphery of the heating element and flowing into the cooking cavity. In this way, the flow path of the air flow in the cooking cavity, the first flow channel and the second flow channel is further defined, so that the hot air can be fully disturbed in the cooking cavity, and it can be ensured that the hot air is in full contact with different parts of the food material.

[0019] In some embodiments, optionally, at least a part of the heating element is located at the top of the cooking cavity.

[0020] In this embodiment, the matching structure of the heating element and the cooking cavity is further defined such that at least a part of the heating element is located at the top of the cooking cavity. That is, a part of the heating element is located at the top of the cooking cavity, or the whole heating element is located at the top of the cooking cavity.

[0021] In this way, when the driving element drives the fan to rotate, the air flow at the bottom of the cooking cavity flows to the top of the cooking cavity and then to the second flow channel. After fully exchanging heat with the heating element via the first flow channel, it returns to the bottom of the cooking cavity from the outlet of the first flow channel. That is, it is realized that the hot air can flow from the bottom of the food material placed in the cooking cavity to the top of the food material to fully heat and bake the food material, which can ensure the balance of the temperatures on different sides of the food material, ensure that the food material is heated evenly, and is beneficial to improving the cooking taste of the food material.

[0022] In some embodiments, optionally, the fan is an axial flow fan. When the fan rotates, the hot air flows from the bottom end of the second flow channel to the top end of the second flow channel and then to the first flow channel, and is guided to both sides along the first flow channel.

[0023] In this embodiment, the matching structure of the fan, the first flow channel and the second flow channel is further defined.

[0024] The fan is an axial flow fan. When the fan rotates, it flows from the bottom end of the second flow channel to the top end of the second flow channel and then to the first flow channel, and is guided to both sides along the first flow channel. The air flow flows from the bottom to the top in the second flow channel and is guided to both sides along the flow channel wall of the first flow channel. That is, the air flow diverges around, taking away the heat on the heating element, fully exchanging heat with the heating element, and then dissipating along the heating element from the periphery of the heating element and flowing into the cooking cavity.

[0025] In some embodiments, optionally, the heating element includes: a guide cylinder, which is arranged at an interval from the cavity wall of the cooking cavity, and the inner surface of the guide cylinder encloses the second flow channel; a heating part, which is connected to the periphery of the guide cylinder, and the heating part encloses a part of the flow channel wall of the first flow channel.

[0026] In this embodiment, the structure of the heating element is further defined, so that the heating element includes a guide tube and a heating portion. The heating portion is connected to the peripheral side of the guide tube.

[0027] It can be understood that the inner surface of the guide tube encloses the second flow channel, the heating portion is connected to the outer surface of the guide tube, and the heating portion is arranged around the guide tube.

[0028] The heating part encloses a part of the flow channel wall of the first flow channel, so that the airflow in the second flow channel can smoothly flow to the first flow channel enclosed by the heating part and the inner wall of the electromagnetic component. This arrangement provides effective structural support for the use requirements of guiding the flow from the cooking cavity to the second flow channel and returning to the cooking cavity through the first flow channel.

[0029] Optionally, the electromagnetic component is used to drive the guide tube to generate heat.

[0030] In some embodiments, optionally, the heating part is an arc-shaped plate; the distance from the outer edge of the heating part to the bottom of the cooking cavity is smaller than the distance from the connection between the heating part and the guide tube to the bottom of the cooking cavity.

[0031] In this embodiment, the matching structure between the heating element and the appliance body is further defined.

[0032] The heating part is an arc-shaped plate, and the distance from the outer edge of the heating part to the bottom of the cooking cavity is smaller than the distance from the connection between the heating part and the guide tube to the bottom of the cooking cavity. That is, the heating part is a disc-shaped structure, and this arrangement makes it easier for the airflow to be directed downward along the height direction of the appliance body to the cooking cavity when the fan blade rotates, so that it is easier for the airflow to circulate in the cooking cavity to ensure the effective contact area and contact angle between the hot air and the food, thereby ensuring the uniformity and consistency of heating the food and ensuring the cooking taste of the food.

[0033] In addition, this arrangement is conducive to reducing the outer diameter of the heating element while ensuring that the airflow guidance effect remains unchanged.

[0034] Moreover, this arrangement is more conducive to the airflow flowing toward the bottom of the cooking cavity along the extension direction of the heating part, which is beneficial to reducing wind energy loss and improving the working efficiency of the cooking appliance.

[0035] In some embodiments, optionally, the electromagnetic component includes: a support plate, the support plate is formed as a channel wall that encloses another part of the first channel; a coil, the coil is arranged on a side of the support plate away from the heating element, and the coil is arranged along the extension direction of the heating part.

[0037] As the installation carrier of the coil, the support plate has the function of installing and fixing the coil, which can ensure the matching size of the coil and the heating element, and provide reliable structural support for the electromagnetic component to effectively drive the heating element to generate heat.

[0038] It can be understood that when the coil is energized, an alternating magnetic field can be generated, and under the action of the alternating magnetic field, the heating element with magnetic conductivity can generate heat. That is, through the interaction between the electromagnetic element and the heating element with magnetic conductivity, the temperature of the heating element can be rapidly increased in a short time. At the same time, driven by the driving element, the fan blade rotates in the second flow channel to quickly generate hot air in the cooking cavity.

[0039] Furthermore, the coil is arranged on the side of the support plate away from the heating element, and the coil is arranged along the extension direction of the heating part, that is, the shape of the coil is arc-shaped, and the shape of the coil is adapted to the shape of the heating part, which can ensure that the distance between the coil and the heating part is basically consistent, providing structural support for the electromagnetic component to drive the heating element to generate balanced heat.

[0040] In some embodiments, optionally, the appliance body further includes: an inner cover, which is located between the electromagnetic component and the driving component; the cooking appliance further includes a connecting shaft, the driving component is connected to the connecting shaft, and the connecting shaft passes through the inner cover and the support plate and is connected to the fan blade.

[0041] In this embodiment, the structure of the device body is further defined.

[0042] The device body further comprises an inner cover, which is located between the electromagnetic component and the driving component, that is, the electromagnetic component is located on a first side of the inner cover, the driving component is located on a second side of the inner cover, and the first side and the second side of the inner cover are arranged opposite to each other. In other words, the inner cover has the function of separating the electromagnetic component and the driving component.

[0043] In this way, hot air at the electromagnetic component can be prevented from flowing to the driving component, heat transfer can be reduced, and the temperature at the driving component is reduced, providing effective and reliable structural support for extending the service life of the driving component.

[0044] Optionally, the drive member comprises a motor.

[0045] The cooking appliance further comprises a connecting shaft, the driving member is connected to the connecting shaft, the connecting shaft passes through the inner cover and the supporting plate and is connected to the fan blade.

The electronic control board is disposed on the appliance body, and the appliance body serves as the installation carrier of the electronic control board, having the function of installing and fixing the electronic control board.

[0048] The electronic control board and the driving member are located on the same side of the inner lid, and the inner lid has the function of separating the electromagnetic member, the electronic control board, and the driving member.

[0049] In this way, it is possible to prevent the hot air at the electromagnetic member from flowing to the driving member and the electronic control board, reduce heat transfer, and is beneficial to reducing the temperature at the driving member and the electronic control board, providing an effective and reliable structural support for extending the service life of the driving member and the electronic control board.

That is, the air outlet is in communication with the electronic control board, the air outlet is in communication with the electromagnetic member, and the air outlet is in communication with the driving member, so that the heat at any one of the electronic control board, the driving member, and the electromagnetic member can be discharged from the appliance body through the air outlet, ensuring that the temperature at any one of the electronic control board, the driving member, and the electromagnetic member is controllable.

[0051] In some embodiments, optionally, the portion of the support plate opposite to the guide cylinder is an arc section, and the arc section is smoothly transitioned with the installation section.

[0052] In this embodiment, the structure of the support plate is further defined such that the portion of the support plate opposite to the guide cylinder is an arc section. The arc section is connected to the installation section, and the arc section is smoothly transitioned with the installation section. That is, the support plate is an arc-shaped plate. In this way, the resistance to the air flow can be reduced, the energy consumption during the rotation of the wind blade can be reduced, and it is beneficial to guide the air flow downward along the first flow path into the cooking cavity. In this way, it is beneficial to the circulation of the air flow in the cooking cavity.

[0053] And this setting enables the balance and consistency of the flow disturbance to be ensured when the wind blade rotates, which is beneficial to reducing the air flow collision, reducing the flow loss of the air flow, enabling more energy to be converted into dynamic pressure, and improving the air volume.

[0054] In some embodiments, optionally, the heating element further includes a connecting section, and the connecting section is connected to the periphery of the heating portion and is connected to the appliance body.

[0055] In this embodiment, the structure of the heating element is further defined such that the heating element further includes a connecting section, and the connecting section is connected to the periphery of the heating portion and is used for the installation and positioning of the heating portion.

[0056] That is, the connecting section is connected to the appliance body.

[0057] In some embodiments, optionally, the number of the connecting sections is multiple, and the multiple connecting sections are arranged at intervals along the circumferential direction of the heating portion.

[0058] In this embodiment, the number of connecting segments is multiple, and the multiple connecting segments are arranged at intervals along the circumferential direction of the heating part. This arrangement increases the connection area between the heating element and the appliance body, and the heating element can be assembled and connected to the appliance body from multiple directions and angles, which is beneficial to enhancing the stability and reliability of the installation of the heating element.

[0059] In addition, since the multiple connecting segments are arranged at intervals along the circumferential direction of the heating part, any two adjacent connecting segments are arranged at intervals.

The appliance body 100 includes an electromagnetic member 120, and the electromagnetic member 120 is used to drive the heating element 200 to generate heat. The food is placed in the cooking cavity 110. When the cooking appliance 10 works, the electromagnetic member 120 is powered on to generate a magnetic field.

The heating element 200 can heat the air to form hot air, and the hot air is used to cook the food in the cooking cavity 110.

[0101] Among them, the heating element 200 is arranged below the electromagnetic member 120.

[0107] In this embodiment, the matching structure of the heating element 200 and the utensil body 100 is further defined, so that the first flow channel 300 is arranged around the second flow channel 210. Specifically, the outer edge of the heating element 200 and the electromagnetic element 120 enclose an outlet 310 of the first flow channel 300, that is, the airflow in the first flow channel 300 flows back into the cooking cavity 110 through the outlet 310.

[0108] The positional relationship between the first flow channel 300 and the second flow channel 210 is defined so that the first flow channel 300 is disposed around the second flow channel 210. For example, the first flow channel 300 is an annular flow channel, and the annular flow channel is disposed around the second flow channel 210. For example, the first flow channel 300 is an arcuate flow channel, and the arcuate flow channel is disposed around the second flow channel 210.

[0109] This arrangement allows the airflow to enter the first flow channel 300 from the second flow channel 210, and then radiate to the surroundings, taking away the heat on the heating element 200, and after fully exchanging heat with the heating element 200, radiate from the surroundings of the heating element 200 along the heating element 200 and flow to the cooking cavity 110. This arrangement allows hot air to be sent into the cooking cavity 110 from multiple directions and multiple angles, so that the hot air can flow to the food from multiple directions and multiple angles to fully heat and bake the food, and can ensure the cooking taste of the food.

[0110] In some embodiments, optionally, the fan blade 400 is an axial flow fan blade, and when the fan blade 400 rotates, hot air flows from the bottom end 212 of the second flow channel to the top end 214 of the second flow channel to the first flow channel 300, and is guided to both sides along the first flow channel 300.

[0111] In this embodiment, the matching structure of the fan blade 400, the first flow channel 300 and the second flow channel 210 is further defined.

[0112] The fan blade 400 is an axial flow fan blade. The fan blade 400 rotates, flows from the bottom end 212 of the second flow channel to the first flow channel 300 through the top end 214 of the second flow channel, and is guided to both sides along the first flow channel 300. The airflow flows from bottom to top in the second flow channel 210 to the first flow channel 300, and is guided to both sides along the flow channel wall of the first flow channel 300. That is, the airflow radiates to the surroundings, takes away the heat from the heating element 200, and after fully exchanging heat with the heating element 200, it radiates from the surroundings of the heating element 200 along the heating element 200 and flows to the cooking chamber 110.

[0113] In some embodiments, optionally, the outer edge of the heat generating element 200 and the inner wall 126 of the electromagnetic element enclose an outlet 310 of the first flow channel 300 .

[0114] The outlet 310 is disposed around the second flow channel 210 .

[0115] In this embodiment, the matching structure of the heating element 200 and the appliance body 100 is further defined, so that the outer edge of the heating element 200 and the inner wall 126 of the electromagnetic element enclose the outlet 310 of the first flow channel 300, that is, the airflow in the first flow channel 300 flows back to the cooking cavity 110 through the outlet 310.

[0116] The positional relationship between the outlet 310 and the second flow channel 210 is defined so that the outlet 310 is disposed around the second flow channel 210. For example, the outlet 310 is an annular opening disposed around the second flow channel 210. For example, the outlet 310 is an arc-shaped opening disposed around the second flow channel 210.

[0117] By limiting the positional relationship between the outlet 310 and the second flow channel 210, the airflow enters the first flow channel 300 from the second flow channel 210, and then radiates to the surroundings, taking away the heat on the heating element 200, and after fully exchanging heat with the heating element 200, radiates from the surroundings of the heating element 200 along the heating element 200 and flows to the cooking cavity 110. This arrangement allows hot air to be sent into the cooking cavity 110 from multiple directions and multiple angles, so that the hot air can flow to the food from multiple directions and multiple angles to fully heat and bake the food, and can ensure the cooking taste of the food.

[0118] In some embodiments, optionally, a second flow channel 210 is provided in the middle of the heating element 200 .

[0119] In this embodiment, the structure of the heating element 200 is further defined, so that the middle part of the heating element 200 is provided with a second flow channel 210, so that the driving element 500 drives the fan blade 400 to rotate, and the airflow in the cooking cavity 110 flows to the second flow channel 210 in the middle part of the heating element 200, and flows to the first flow channel 300, and then dissipates to the surroundings, takes away the heat on the heating element 200, and after fully exchanging heat with the heating element 200, dissipates from the surroundings of the heating element 200 along the heating element 200 and flows to the cooking cavity 110. In this way, the flow path of the airflow in the cooking cavity 110, the first flow channel 300 and the second flow channel 210 is further defined, so that the hot air can be fully disturbed in the cooking cavity 110, and it can ensure that the hot air is fully in contact with different parts of the food.

[0120] In some embodiments, optionally, Figure 1 As shown, at least a portion of the heat generating element 200 is located at the top of the cooking cavity 110 .

[0121] In this embodiment, the matching structure of the heating element 200 and the cooking cavity 110 is further defined, so that at least a portion of the heating element 200 is located at the top of the cooking cavity 110. That is, a portion of the heating element 200 is located at the top of the cooking cavity 110, or the heating element 200 is entirely located at the top of the cooking cavity 110.

[0122] In this way, the driving member 500 drives the wind wheel 400 to rotate, and the air flow at the bottom of the cooking cavity 110 flows towards the top of the cooking cavity 110 and then towards the second flow channel 210. After fully exchanging heat with the heating element 200 via the first flow channel 300, it returns to the bottom of the cooking cavity 110 from the outlet 310 of the first flow channel 300. That is to say, it realizes that the hot air can flow from the bottom of the food placed in the cooking cavity 110 to the top of the food, so as to fully heat and bake the food, ensure the balance of the temperatures on different sides of the food, ensure that the food is heated evenly, and is beneficial to improving the cooking taste of the food.

[0123] In some other embodiments, at least a part of the heating element 200 is located at the bottom of the cooking cavity 110.

[0124] In some other embodiments, at least a part of the heating element 200 is located at the side of the cooking cavity 110.

[0125] In some embodiments, optionally, from the middle of the heating element 200 to the outer edge of the heating element 200, the distance from the first flow channel 300 to the bottom of the cooking cavity 110 gradually decreases.

[0126] In this embodiment, the cooperation structure of the heating element 200 and the appliance body 100 is further defined, so that from the middle of the heating element 200 to the outer edge of the heating element 200, the distance from the first flow channel 300 to the bottom of the cooking cavity 110 gradually decreases.

[0127] This setting makes it beneficial for the air flow to be guided downward along the height direction of the appliance body 100 to the cooking cavity 110 when the wind wheel 400 rotates. In this way, it is beneficial for the air flow to circulate in the cooking cavity 110 to ensure the effective contact area and contact angle between the hot air and the food, and further ensure the uniformity and consistency of the heating of the food, and ensure the cooking taste of the food.

[0128] In addition, from the middle of the heating element 200 to the outer edge of the heating element 200, the distance from the first flow channel 300 to the bottom of the cooking cavity 110 gradually decreases, which is beneficial to reducing the outer diameter of the heating element 200 while ensuring the same air flow guiding effect.

[0129] And this setting is more conducive to the air flow flowing towards the bottom of the cooking cavity 110 along the extension direction of the first flow channel 300, beneficial to reducing the wind energy loss, and beneficial to improving the working efficiency of the cooking appliance 10.

[0130] Optionally, the first flow channel 300 extends in a dish shape.

[0131] In some embodiments, optionally, as Figure 1 、 Figure 2 and Figure 3 shown, the heating element 200 includes a diversion cylinder 220 and a heating part 230.

[0132] The flow guide cylinder 220 is arranged at an interval from the cavity wall of the cooking cavity 110.

[0133] The inner surface of the flow guide cylinder 220 encloses a second flow channel 210.

[0134] The heating part 230 is connected to the circumferential side of the flow guide cylinder 220.

[0135] The heating part 230 encloses a part of the flow channel wall of the first flow channel 300.

[0136] In this embodiment, the structure of the heating element 200 is further defined such that the heating element 200 includes a flow guide cylinder 220 and a heating part 230. The heating part 230 is connected to the circumferential side of the flow guide cylinder 220.

[0137] It can be understood that the inner surface of the flow guide cylinder 220 encloses a second flow channel 210, the heating part 230 is connected to the outer surface of the flow guide cylinder 220, and the heating part 230 is arranged around the flow guide cylinder 220.

[0138] The heating part 230 encloses a part of the flow channel wall of the first flow channel 300. In this way, the air flow in the second flow channel 210 can smoothly flow to the first flow channel 300 enclosed by the heating part 230 and the inner wall 126 of the electromagnetic part. This setting provides effective structural support for the use requirement of draining from the cooking cavity 110 to the second flow channel 210 and flowing back to the cooking cavity 110 via the first flow channel 300.

[0139] Optionally, the electromagnetic part 120 is used to drive the flow guide cylinder 220 to generate heat.

[0140] In some embodiments, optionally, the heating part 230 is an arc-shaped plate.

[0141] The distance from the outer edge of the heating part 230 to the bottom of the cooking cavity 110 is less than the distance from the connection part of the heating part 230 and the flow guide cylinder 220 to the bottom of the cooking cavity 110.

[0142] In this embodiment, the matching structure of the heating element 200 and the appliance body 100 is further defined.

[0143] The heating part 230 is an arc-shaped plate, and the distance from the outer edge of the heating part 230 to the bottom of the cooking cavity 110 is less than the distance from the connection part of the heating part 230 and the flow guide cylinder 220 to the bottom of the cooking cavity 110. That is to say, the heating part 230 is in a dish-shaped structure. This setting makes it beneficial for the air flow to be guided downward along the height direction of the appliance body 100 when the fan blade 400 rotates. In this way, it is beneficial for the air flow to circulate inside the cooking cavity, so as to ensure the effective contact area and contact angle between the hot air and the food ingredients, and further ensure the uniformity and consistency of heating the food ingredients, and ensure the cooking taste of the food ingredients.

[0144] In addition, this arrangement is conducive to reducing the outer diameter of the heating element 200 while ensuring that the airflow guiding effect remains unchanged.

[0145] Moreover, this arrangement is more conducive to the airflow flowing toward the bottom of the cooking cavity 110 along the extension direction of the heating portion 230 , which is beneficial to reducing wind energy loss and improving the working efficiency of the cooking appliance 10 .

[0146] In some embodiments, optionally, the electromagnetic component 120 includes: a support plate 122, the support plate 122 is formed as a channel wall that encloses another part of the first channel 300; a coil 124, the coil 124 is arranged on the side of the support plate 122 away from the heating element 200, and the coil 124 is bent along the extension direction of the heating portion 230.

[0147] In this embodiment, the structure of the electromagnetic member 120 is further defined, such that the electromagnetic member 120 includes a support plate 122 and a coil 124. The support plate 122 is formed as a channel wall that encloses another portion of the first channel 300.

It can ensure the matching size of the coil 124 and the heating element 200 , and provide a reliable structural support for the electromagnetic element 120 to effectively drive the heating element 200 to generate heat.

[0149] It is understandable that when the coil 124 is energized, an alternating magnetic field can be generated, and under the action of the alternating magnetic field, the heating element 200 with magnetic conductivity can generate heat. That is, through the interaction between the electromagnetic element 120 and the heating element 200 with magnetic conductivity, the temperature of the heating element 200 can be rapidly increased in a short time. At the same time, under the drive of the driving element 500, the fan blade 400 rotates in the second flow channel 210, so that hot air is quickly generated in the cooking cavity 110.

[0150] Furthermore, the coil 124 is arranged on the side of the support plate 122 away from the heating element 200, and the coil 124 is bent along the extension direction of the heating part 230, that is, the shape of the coil 124 is arc-shaped, and the shape of the coil 124 is adapted to the shape of the heating part 230, which can ensure that the distance between the coil 124 and the heating part 230 is basically consistent, thereby providing structural support for the electromagnetic component 120 to drive the heating element 200 to generate heat evenly.
