[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0051] According to the first aspect of this application, see Figure 1 , Figure 2 and Figure 3 The present disclosure provides a heating component. The heating component includes a magnetic heating element 1, a coil 2 and an insulating element 3, wherein the coil 2 is disposed on the magnetic heating element 1, and the insulating element 3 is disposed between the coil 2 and the magnetic heating element 1.

[0052] Among them, the coil 2 is suitable for generating heat under the action of direct current and conducting heat to the magnetic heating element 1. The coil 2 is also suitable for generating an alternating magnetic field under the action of alternating current, so that the magnetic heating element 1 generates heat under the action of the alternating magnetic field.

[0053] It is understandable that when direct current is transmitted to the coil 2, the coil 2 will generate heat under the action of the direct current, and the heat generated by the coil 2 is transferred to the magnetic heating element 1 through the insulating member 3, so that the magnetic heating element 1 generates heat, thereby achieving heating of the magnetic heating element 1. When alternating current is transmitted to the coil 2, the coil 2 will generate an alternating magnetic field under the action of the alternating current. At this time, the magnetic heating element 1 is in the alternating magnetic field, and the magnetic heating element 1 will generate heat under the action of the alternating magnetic field, thereby achieving rapid heating of the magnetic heating element 1 and improving the heating effect. In other words, in the present application, the coil 2 can be used as an inductor coil 2 for electromagnetic heating or as an electronic heating wire for resistance heating, thereby achieving reuse of the coil 2, effectively simplifying the structure of the heating component, and reducing the manufacturing cost of the heating component.

[0054] It can be understood that compared with the related art, the present application directly arranges the magnetic heating element 1 and the coil 2 on the inner and outer sides of the insulating element 3 respectively, without the need for structures such as a winding bracket, which effectively simplifies the structure of the heating component and reduces the cost of the heating component.

[0055] When the coil 2 is used as an inductor coil 2 for electromagnetic heating, since the coil 2 and the magnetic heating element 1 are separated only by the insulating member 3, the coil 2 is closer to the magnetic heating element 1, so that when the magnetic heating element 1 generates heat under the action of the alternating magnetic field, the speed of eddy current generation is accelerated, thereby effectively improving the heating rate and magnetothermal conversion rate of the magnetic heating element 1.

[0056] It is understandable that when the tobacco product is heated by the heating assembly, AC power can be supplied to the coil 2 in the initial preheating stage, so that the magnetic heating element 1 heats up quickly, thereby achieving the purpose of rapid temperature rise, shortening the preheating time, and providing sufficient smoke in the first puff, thereby improving the consumer experience. In the subsequent constant temperature stage, DC power can be supplied to the coil 2 to maintain the temperature by means of resistance heating, thereby achieving the purpose of saving energy consumption.

[0057] In some examples, the insulating member 3 is sleeved on the outer wall of the magnetic heating member 1, and the coil 2 is connected to the outer wall of the insulating member 3. Alternatively, the magnetic heating member 1 is sleeved on the outer wall of the insulating member 3, and the coil 2 is connected to the inner wall of the insulating member 3.

[0058] In some examples, the magnetic heating element 1 is, for example, a carbon steel piece or a silicon steel piece or any other suitable magnetic conductive body that can conduct electricity.

[0059] In some embodiments, see Figure 4The heating component also includes a resistance heating control module 4 and an electromagnetic heating control module 5, both of which are connected to the coil 2, the resistance heating control module 4 is used to transmit direct current to the coil 2, and the electromagnetic heating control module 5 is used to transmit alternating current to the coil 2.

[0060] It is understandable that by transmitting direct current to the coil 2 through the resistance heating control module 4, the coil 2 can be heated, and the heat generated by the coil 2 is transferred to the magnetic heating element 1, thereby heating the magnetic heating element 1. By transmitting alternating current to the coil 2 through the electromagnetic heating control module 5, the coil 2 can generate an alternating magnetic field, so that the magnetic heating element 1 is heated under the action of the alternating magnetic field, thereby heating the magnetic heating element 1.

[0061] In some embodiments, see Figure 4 The heating component also includes a switch switching module 6, and the resistance heating control module 4 and the electromagnetic heating control module 5 are both connected to the coil 2 through the switch switching module 6, so that one of the resistance heating control module 4 and the electromagnetic heating control module 5 is connected to the coil 2.

[0062] It can be understood that the switch module 6 can control the on / off of the resistance heating control module 4 and the coil 2, and can control the on / off of the electromagnetic heating control module 5 and the coil 2. Furthermore, the switch module 6 can control the type of current delivered to the coil 2, and can control the heating component to switch between resistance heating and electromagnetic heating.

[0063] For some examples, see Figure 4 , Figure 5 and Figure 6 The switch switching module 6 includes a first switch module 61 and a second switch module 62. The first switch module 61 connects the resistance heating control module 4 and the coil 2, and the second switch module 62 connects the electromagnetic heating control module 5 and the coil 2. That is, the first switch module 61 can control the on-off between the resistance heating control module 4 and the coil 2, and the second switch module 62 can control the on-off between the electromagnetic heating control module 5 and the coil 2.

[0064] In some embodiments, the coil 2 includes a first coil and a second coil arranged at intervals, the resistance heating control module 4 and the electromagnetic heating control module 5 are both connected to the first coil, and one of the resistance heating control module 4 and the electromagnetic heating control module 5 is connected to the second coil.

[0065] It is understandable that the first coil can receive both direct current and alternating current, that is, the first coil can be used as a heating wire for resistance heating or as an inductor coil 2 for electromagnetic heating. The second coil is fixed as a heating wire for resistance heating.

[0066] In specific use, AC is transmitted to the first coil, so that the first coil generates an alternating magnetic field, and the magnetic heating element 1 generates heat under the action of the alternating magnetic field, thereby realizing rapid heating of the magnetic heating element 1. At the same time, DC is transmitted to the second coil, or current is temporarily not transmitted to the second coil. Thus, electromagnetic heating is realized by only using part of the coil 2, which can achieve rapid heating of the magnetic heating element 1 and save energy.

[0067] In some embodiments, the coil 2 includes at least two sections of the third coil, and the third coils in different sections have different densities.

[0068] It is understandable that the density of the third coils in one section is greater than that of the third coils in other sections, and the greater the density, the faster the heating speed. Thus, rapid heating can be achieved at the third coils in one section.

[0069] Exemplarily, coil 2 includes two sections of the third coil, wherein the density of one section of the third coil is greater than the density of the other section of the third coil. When the tobacco product is heated by the heating component, the tobacco product at the corresponding position of one section of the third coil will heat up quickly, thereby achieving rapid smoke output, avoiding long waiting time for the user, and improving the user experience.

[0070] In some embodiments, the coil 2 is a printed coil 2. It is understood that forming the coil 2 on the side of the insulating member 3 away from the magnetic heating element 1 through a printing process is conducive to controlling the resistance and inductance of the coil 2, so that the coil 2 can be used as an inductor coil 2 for electromagnetic heating or as an electronic heating wire for resistance heating.

[0071] In some embodiments, the coil 2 is a PI film. It is understood that using the PI film as the coil 2 is conducive to controlling the resistance and inductance of the coil 2 when setting the coil 2, so that the coil 2 can be used as an inductor coil 2 for electromagnetic heating or as an electronic heating wire for resistance heating. At the same time, the maximum operating temperature of the coil 2 can be increased to prevent the coil 2 from melting during operation.

[0072] In some embodiments, the resistance value of the coil 2 is between 300 milliohms and 1.2 ohms, so that the coil 2 can be used as an inductor coil 2 for electromagnetic heating or as an electronic heating wire for resistance heating.

[0073] It is understandable that when the resistance value of the coil 2 is less than 300 milliohms, the heat generated by the coil 2 as a heating wire for resistive heating is low and it is difficult to meet the heating requirements. When the resistance value of the coil 2 is higher than 1.2 ohms, the coil 2 is prone to overheating during operation.

[0074] In some embodiments, see Figure 1 The heating component further includes a temperature detection module 7, and the temperature detection module 7 is used to detect the temperature of at least one of the insulating member 3 and the coil 2.

[0075] It is understandable that by detecting the temperature of the insulating member 3 through the temperature detection module 7, the temperature of the insulating member 3 can be known, and the insulating member 3 is connected to the magnetic heating member 1, and thus the temperature of the magnetic heating member 1 can be known. By detecting the temperature of the coil 2 through the temperature detection module 7, the temperature of the coil 2 can be known, and the coil 2 is connected to the magnetic heating member 1 through the insulating member 3, and thus the temperature of the magnetic heating member 1 can be known.

[0076] That is to say, by setting up the temperature detection module 7, the temperature of the magnetic heating element 1 can be indirectly known, and the temperature of the magnetic heating element 1 can be monitored, so that AC or DC power can be delivered to the coil 2 according to the temperature control of the magnetic heating element 1. The current delivered to the coil 2 can also be controlled according to the temperature of the magnetic heating element 1, so that the temperature of the magnetic heating element 1 is within a preset temperature range.

[0077] For some examples, see Figure 1 The temperature detection module 7 further includes a temperature detection member 71, a detection end of the temperature detection member 71 is connected to the insulating member 3, and the temperature detection member 71 is used to detect the temperature of the insulating member 3. The temperature detection member 71 is, for example, a thermocouple.

[0078] For some examples, see Figure 1 The temperature detection module 7 also includes a control component and a resistance detection component 72. The resistance detection component 72 is connected to the coil 2, and the resistance detection component 72 is used to detect the resistance of the coil 2. The control component is connected to the resistance detection component 72, and the control component is used to determine the temperature of the coil 2 according to the detection data of the resistance component.

[0079] In some embodiments, see Figure 1 The heating component also includes a heat insulating member 8, which is sleeved on the magnetic heating member 1, and the coil 2 is located between the heat insulating member 8 and the insulating member 3.

[0080] It is understandable that the coil 2 and the magnetic heating element 1 are both located in the thermal insulation 8. When the coil 2 generates heat, the thermal insulation 8 can reduce the heat dissipated from the coil 2 to the outside, reducing heat loss, so that more heat from the coil 2 can be transferred to the magnetic heating element 1, improving the heat transfer efficiency and the heating speed of the magnetic heating element 1. When the magnetic heating element 1 generates heat under the action of the alternating magnetic field, the thermal insulation 8 can reduce the heat dissipated from the magnetic heating element 1 to the outside, reducing heat loss.

[0081] Exemplarily, the heat insulating member 8 is, for example, heat insulating cotton or a heat insulating board or any other suitable structural member with a heat insulating function.

[0082] In some embodiments, see Figure 1 The heating component also includes a magnetic field isolator 9, which is sleeved on the magnetic conductive heating element 1, and the coil 2 is located between the insulating element 3 and the magnetic field isolator 9.

[0083] It can be understood that the coil 2 and the magnetic heating element 1 are both located in the magnetic field isolation element 9. Since the magnetic field isolation element 9 has the function of isolating the magnetic field, when alternating current is transmitted to the coil 2 and the coil 2 generates an alternating magnetic field, the magnetic field isolation element 9 can effectively prevent the magnetic circuit from leaking, which is beneficial to improving the heating effect of the magnetic heating element 1.

[0084] Exemplarily, the magnetic field isolation component 9 is, for example, a ferrite or silicon steel component or any other suitable structural component having a magnetic field isolation function.

[0085] According to the second aspect of this application, please refer to Figure 7 The present disclosure provides a heating component. The heating component includes a magnetic heating element 1, an insulating element 3 and a conductor 10, wherein a heating chamber is arranged inside the magnetic heating element 1, the insulating element 3 is arranged on the outer periphery of the magnetic heating element 1, and the conductor 10 is wound around the insulating element 3, wherein the resistance value of the conductor 10 is between 300 milliohms and 1.2 ohms.

[0086] It is understandable that the resistance value of the conductor 10 is set between 300 milliohms and 1.2 ohms. When direct current is transmitted to the conductor 10, the conductor 10 can be used as a heating element, and the heat of the conductor 10 can be transferred to the magnetic heating element 1 to achieve heating of the magnetic heating element 1; when alternating current is transmitted to the conductor 10, the conductor 10 will generate an alternating magnetic field, so that the magnetic heating element 1 generates heat under the action of the alternating magnetic field, and the magnetic heating element 1 is quickly heated, thereby improving the heating effect. In other words, the coil 2 can be used as an inductor coil 2 for electromagnetic heating, or as an electronic heating wire for resistance heating, so as to achieve the reuse of the coil 2, effectively simplify the structure of the heating component, and reduce the manufacturing cost of the heating component.

[0087] It can be understood that the magnetic heating element 1 has a heating cavity, and the magnetic heating element 1 can be directly put on the tobacco product to be heated, so that the tobacco product is heated evenly, the smoke generated is sufficient and lasts for a long time, and the consumer experience is improved.

[0088] According to a third aspect of the present application, the present disclosure provides an atomizer, which includes the above-mentioned heating assembly.

[0089] It is understandable that when direct current is transmitted to the coil 2, the coil 2 will generate heat under the action of the direct current, and the heat generated by the coil 2 is transferred to the magnetic heating element 1 through the insulating member 3, so that the magnetic heating element 1 generates heat, thereby heating the magnetic heating element 1. When alternating current is transmitted to the coil 2, the coil 2 will generate an alternating magnetic field under the action of the alternating current. At this time, the magnetic heating element 1 is in the alternating magnetic field, and the magnetic heating element 1 will generate heat under the action of the alternating magnetic field, thereby rapidly heating the magnetic heating element 1 and improving the heating effect. In other words, in the present application, the coil 2 can be used as an inductor coil 2 for electromagnetic heating or as an electronic heating wire for resistance heating, thereby reusing the coil 2, effectively simplifying the structure of the heating component, reducing the manufacturing cost of the heating component, and further reducing the cost of the atomizer.

[0090] According to the fourth aspect of this application, please refer to Figure 8 The present disclosure provides a control method for a heating component. The heating component comprises a magnetic heating element 1, a coil 2 and an insulating element 3, wherein the coil 2 is arranged on the magnetic heating element 1, and the insulating element 3 is arranged between the coil 2 and the magnetic heating element 1. The control method comprises:

[0091] Step 101: When the temperature inside the magnetic heating element 1 is lower than a preset temperature, AC power is transmitted to at least a portion of the coil 2.

[0092] It is understandable that the temperature inside the magnetic heating element 1 is obtained to determine whether the temperature inside the magnetic heating element 1 is lower than the preset temperature. When it is determined that the temperature inside the magnetic heating element 1 is lower than the preset temperature, it means that it is difficult for the magnetic heating element 1 to effectively heat the tobacco product. Then, alternating current is transmitted to at least part of the coil 2, so that at least part of the coil 2 generates an alternating magnetic field under the action of the alternating current, so that the magnetic heating element 1 quickly heats up under the action of the alternating magnetic field, so as to quickly increase the temperature inside the magnetic heating element 1.

[0093] Step 102: Determine that the temperature inside the magnetic heating element 1 reaches the preset temperature, and supply direct current to the coil 2 to keep the temperature of the magnetic heating element 1 at or above the preset temperature.

[0094] It can be understood that when it is determined that the temperature inside the magnetic heating element 1 reaches the preset temperature, direct current is supplied to the coil 2, so that the coil 2 generates heat under the action of the direct current, and the heat of the coil 2 is transferred to the magnetic heating element 1, so that the temperature of the magnetic heating element 1 can be maintained at or above the preset temperature, thereby avoiding long-term use of electromagnetic heating to save energy.

[0095] The present application compares and judges the temperature inside the magnetic heating element 1 with the preset temperature. When the temperature inside the magnetic heating element 1 is lower than the preset temperature, AC is transmitted to at least part of the coil 2 to achieve electromagnetic heating, so that the temperature of the magnetic heating element 1 rises rapidly. When the temperature of the magnetic heating element 1 reaches the preset temperature, DC is transmitted to the coil 2, so that the coil 2 generates heat as a heating body, and the heat is transferred to the magnetic heating element 1 to heat the magnetic heating element 1, so as to control the temperature inside the magnetic heating element 1, so that the temperature inside the magnetic heating element 1 can be quickly in a suitable range to heat tobacco products, and the coil 2 can be used as an inductor to achieve electromagnetic heating of the heating component, and can also be used as a heating wire to achieve resistance heating of the heating component, which is conducive to simplifying the structure of the heating component and reducing the cost of the heating component.

[0096] In some examples, the temperature of the magnetic heating element 1 , the coil 2 , or the insulating element 3 may be used to represent the temperature inside the magnetic heating element 1 .

[0097] In some examples, the temperature inside the magnetic heating element 1 can be directly detected by the temperature detection module 7, or the temperature of the magnetic heating element 1 or the coil 2 or the insulating element 3 can be detected by the temperature detection module 7 to achieve indirect detection of the temperature inside the magnetic heating element 1.

[0098] In some embodiments, the coil 2 includes at least a first coil and a second coil that are spaced apart.

[0099] The step of supplying alternating current to at least part of the coil 2 includes: supplying alternating current to the first coil.

[0100] It is understandable that when the temperature inside the magnetic heating element 1 is lower than the preset temperature, alternating current can be transmitted to the first coil, so that the first coil generates an alternating magnetic field, and the magnetic heating element 1 generates heat under the action of the alternating magnetic field, thereby realizing rapid heating of the magnetic heating element 1. At the same time, direct current is transmitted to the second coil, or current is temporarily not transmitted to the second coil. Thus, electromagnetic heating is realized by only using part of the coil 2, which can achieve the effect of saving energy consumption while realizing rapid heating of the magnetic heating element 1.

[0101] The step of supplying direct current to the coil 2 includes: supplying direct current to the second coil.

[0102] It is understandable that at this time, direct current can be only supplied to the second coil without supplying current to the first coil, and the heat generated by the second coil can be used to continue heating the magnetic heating element 1 so that the temperature of the magnetic heating element 1 is maintained at a preset temperature or exceeds the preset temperature, thereby achieving the effect of saving energy.

[0103] Direct current can also be supplied to the first coil and the second coil at the same time, and the heat generated by the first coil and the second coil can be used to continue heating the magnetic heating element 1, so that the temperature of the magnetic heating element 1 is maintained at a preset temperature or exceeds the preset temperature, avoiding continuous supply of alternating current to the first coil, which is beneficial to saving energy consumption.

[0104] In some embodiments, the coil 2 includes at least a first coil and a second coil that are spaced apart.

[0105] The step of delivering alternating current to at least part of the coil 2 includes: delivering alternating current to the first coil. It is understandable that when the temperature inside the magnetic heating element 1 is lower than the preset temperature, alternating current can be delivered to the first coil, so that the first coil generates an alternating magnetic field, and the magnetic heating element 1 generates heat under the action of the alternating magnetic field, thereby achieving rapid heating of the magnetic heating element 1. At the same time, direct current is delivered to the second coil, or current is temporarily not delivered to the second coil. In this way, electromagnetic heating is achieved by using only part of the coil 2, which can save energy while achieving rapid heating of the magnetic heating element 1.

[0106] The step of transmitting direct current to the coil 2 comprises:

[0107] delivering direct current to the first coil;

[0108] A direct current is supplied to the second coil.

[0109] It can be understood that after the temperature inside the magnetic heating element 1 reaches the preset temperature, the alternating current supplied to the first coil is converted into direct current, so that the first coil no longer generates an alternating magnetic field, and as a heating element, the heat generated by the first coil can be transferred to the magnetic heating element 1 to continue heating the magnetic heating element 1, and direct current is supplied to the second coil, and the heat generated by the second coil is used to continue heating the magnetic heating element 1, so that the temperature of the magnetic heating element 1 is maintained at or above the preset temperature, thereby avoiding continuous supply of alternating current to the first coil, thereby achieving the purpose of saving energy.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
