In the related art, the central heating method generally heats the aerosol generating matrix by heating the heating wire with a resistance, and then conducts heat to the surroundings. The resistance heating speed is slow and the heating efficiency is low. Utility Model Content

[0027] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood.

[0028] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0031] See also Figure 1 and Figure 2 The present application provides a heating component 10, which can be used in an atomizing device 100 to heat an aerosol generating substrate 200. The present application also provides an atomizing device 100, which includes the heating component 10 involved in any of the embodiments below. Generally, a receiving chamber 21 is provided in the atomizing device 100, and one end of the receiving chamber 21 has an opening 22 connected to the outside of the atomizing device 100, and the opening 22 can allow the aerosol generating substrate 200 to be inserted into or withdrawn from the receiving chamber 21. The heating component 10 can be arranged at one end of the receiving chamber 21 away from the opening 22. When the aerosol generating substrate 200 is inserted into the receiving chamber 21, the heating component 10 is inserted into the aerosol generating substrate 200 from the end of the aerosol generating substrate 200 close to the heating component 10 to heat the aerosol generating substrate 200.

[0032] See also Figures 3 to 5 The heating component 10 includes a heat-conducting insulating member 11, a magnetic heating element 12 and a magnetic field generating layer 13. The heat-conducting insulating member 11 is provided with a receiving cavity 111. The magnetic heating element 12 is received in the receiving cavity 111 and is used to induce an alternating magnetic field to generate heat. The magnetic field generating layer 13 is provided on the outer surface of the heat-conducting insulating member 11 and is used to provide an alternating magnetic field for the magnetic heating element 12.

[0033] The heating component 10 is inserted into the aerosol generating matrix 200 through the heat-conductive insulating member 11. When the heating component 10 is inserted into the aerosol generating matrix 200, at least a portion of the heat-conductive insulating member 11 is inserted into the interior of the aerosol generating matrix 200, and at the same time, at least a portion of the magnetic heating element 12 disposed therein and the magnetic field generating layer 13 disposed on its outer surface are located inside the aerosol generating matrix 200.

[0034] When a high-frequency alternating current is passed through the magnetic field generating layer 13, an alternating magnetic field is generated, and the magnetic heating element 12 is located in the alternating magnetic field. The change in the magnetic lines of force of the alternating magnetic field generates eddy currents in the magnetic heating element 12, so that the magnetic heating element 12 generates heat and the temperature rises. The heat is transferred to the aerosol generating matrix 200 through the thermally conductive insulating member 11, thereby heating the aerosol generating matrix 200.

[0035] The present application realizes electromagnetic induction heating by arranging a magnetic heating element 12 and a magnetic field generating layer 13, and the speed of electromagnetic induction heating is much greater than the speed of resistance heating, thereby effectively improving the heating efficiency. In addition, the magnetic field generating layer 13 is arranged on the outer surface of the heat-conducting insulating member 11, and is close to the magnetic heating element 12, which is conducive to the magnetic heating element 12 to improve the conversion efficiency of electromagnetic induction between the magnetic field generating layer 13 and the magnetic heating element 12. In addition, since the magnetic field generating layer 13 is arranged on the outer surface of the heat-conducting insulating member 11, when the heat-conducting insulating member 11 is inserted into the interior of the aerosol generating matrix 200, the magnetic field generating layer 13 is inserted into the interior of the aerosol generating matrix 200 along with the heat-conducting insulating member 11, so the heat generated by the resistance of the magnetic field generating layer 13 will be transferred to the aerosol generating matrix 200, which is used to heat the aerosol generating matrix 200, further effectively utilizing the thermal energy. Therefore, the heating assembly 10 provided in the present application greatly improves the heating efficiency.

[0036] See also Figures 3 to 5 The heat-conducting insulating member 11 includes a main body 112 and a tip 113, wherein the tip 113 is connected to one end of the main body 112; the main body 112 is columnar, the magnetic heating element 12 is disposed in the cavity of the main body 112, and the magnetic field generating layer 13 is disposed on the outer surface of the main body 112. By providing the tip 113, when the heat-conducting insulating member 11 is inserted into the aerosol generating matrix 200, the tip 113 is disposed toward the aerosol generating matrix 200 to reduce the resistance generated during the insertion process and improve the insertion efficiency. Among them, the main body 112 is a columnar structure, and the tip 113 is a conical structure, so that the heat-conducting insulating member 11 is needle-shaped as a whole.

[0037] In one embodiment, the heat-conducting insulating member 11 is a member made of ceramic material. Ceramics have good thermal conductivity. The heat-conducting insulating member 11 made of ceramic material can effectively transfer the heat generated by the magnetic heating element 12 to the aerosol generating matrix 200. In addition, ceramics have good insulation performance, which can prevent the magnetic field generating layer 13 from short-circuiting due to contact with the magnetic heating element 12. Of course, in other embodiments, the heat-conducting insulating member 11 can also be made of other materials that are both heat-conducting and insulating.

[0038] In one embodiment, the magnetic field generating layer 13 is provided on the outer surface of the thermally conductive insulating member 11 by thick film printing process and has a layered structure. In other words, the magnetic field generating layer 13 is provided on the outer surface of the thermally conductive insulating member 11 by thick film printing process and has a layered structure.

[0039] The magnetic field generating layer 13 is printed on the outer surface of the thermally conductive insulating member 11 by using a thick film printing process. Due to the process characteristics of the thick film printing process itself, the magnetic field generating layer 13 is layered and is constructed as an integrated structure with the thermally conductive insulating member 11. Compared with the technical solution of arranging the magnetic field generating layer 13 in a winding manner on the circumference of the thermally conductive insulating member 11, the assembly steps are saved, thereby improving the assembly efficiency of the aerosol generating device, and the integrated structure also enhances the connection firmness between the magnetic field generating layer 13 and the thermally conductive insulating member 11.

[0040] In addition, the thickness of the magnetic field generating layer 13 printed on the outer surface of the thermally conductive insulating member 11 is smaller than the thickness of the magnetic field generating layer 13 wound, so that the degree of the magnetic field generating layer 13 protruding from the outer surface of the thermally conductive insulating member 11 is smaller than that of the magnetic field generating layer 13 wound. Therefore, compared with the magnetic field generating layer 13 wound, the magnetic field generating layer 13 set by the thick film printing process generates less resistance when the heating component 10 is inserted into the aerosol generating matrix 200, which is conducive to the insertion of the heating component 10 into the aerosol generating matrix 200. The thickness of the magnetic field generating layer 13 refers to the size of the magnetic field generating layer 13 in the radial direction of the thermally conductive insulating member 11.

[0041] Thick film printing is a high-precision coating technology widely used in the fields of electronics, semiconductors, optoelectronics, optical storage, etc. It requires the use of special equipment to evenly coat the thick film material on the surface of the substrate to form a functional film layer with a thickness of several microns to hundreds of microns. Thick film printing is an existing processing technology and will not be described in detail here.

[0042] It is understandable that in other embodiments, the magnetic field generating layer 13 may be disposed on the outer surface of the thermally conductive insulating member 11 by other methods, such as spraying, laser engraving, or etching.

[0043] Furthermore, in one embodiment, the thickness of the magnetic field generating layer 13 is 10 μm to 100 μm. In specific applications, the thickness of the magnetic field generating layer 13 can be 10 μm, 30 μm, 50 μm, 80 μm, 100 μm, etc.

[0044] See also Figure 3 The magnetic field generating layer 13 extends in a spiral shape along the axial direction of the heat-conducting insulating member 11, and includes a plurality of annular segments 131 connected in sequence, and the width D of each annular segment 131 is 0.3 mm to 10 mm. Setting the width D of the annular segment 131 to 0.3 mm to 10 mm helps to reduce the self-inductance of the magnetic field generating layer 13, and can also reduce the resistance value of the magnetic field generating layer 13, thereby reducing the energy consumption of resistive heating. In specific applications, the width D of the annular segment 131 can be 0.3 mm or 1 mm or 3.5 mm or 6 mm or 8.3 mm or 10 mm, etc.

[0045] Furthermore, in one embodiment, the spacing L between two adjacent ring segments 131 is 0.3 mm to 10 mm. In this way, a short circuit between two adjacent ring segments 131 can be avoided. In a specific application, the spacing L between two adjacent ring segments 131 can be 0.3 mm, 1 mm, 3.5 mm, 6 mm, 8.3 mm, 10 mm, etc.

[0046] In this embodiment, the intervals between two adjacent annular segments 131 are equal. In this way, the multiple annular segments 131 are arranged at equal intervals, so that the magnetic field generating layer 13 generates electromagnetic induction with the magnetic heating element 12 when powered on, so that the magnetic heating element 12 generates heat uniformly.

[0047] Furthermore, in one embodiment, the magnetic field generating layer 13 includes 3 to 20 annular segments 131. This arrangement ensures that the magnetic field generating layer 13 has a certain length, but the total length is not too long, thereby helping to reduce the resistance value of the magnetic field generating layer 13.

[0048] In one embodiment, the resistance of the magnetic field generating layer 13 is less than or equal to 0.05Ω. For example, the resistance of the magnetic field generating layer 13 may be, but is not limited to, 0.01Ω, 0.02Ω, 0.03Ω or 0.04Ω, thereby facilitating the reduction of self-heating of the magnetic field generating layer 13 .

[0049] In this embodiment, the magnetic field generating layer 13 is a silver paste layer disposed on the outer surface of the thermally conductive insulating member 11. Of course, in other embodiments, the magnetic field generating layer 13 may also be other paste layers with low resistivity, such as a gold paste layer or a copper paste layer.

[0050] See also Figures 3 to 5The heating component 10 also includes a reinforcing component 14, which is filled in the accommodating cavity 111 and is used to fix the magnetic heating element. In a specific application, the reinforcing component 14 can be injected into the accommodating cavity 111 by slurry infusion, so as to fix the magnetic heating element 12. The magnetic heating element 12 can be located in the reinforcing component 14 or between the reinforcing component 14 and the thermally conductive insulating member 11.

[0051] By using the slurry infusion method, the reinforcing component 14, the magnetic heating element 12, and the heat-conducting insulating component 11 can be constructed into an integrated structure. On the one hand, the installation firmness of the magnetic heating element 12 is enhanced; on the other hand, there is no air between the reinforcing component 14, the magnetic heating element 12, and the heat-conducting insulating component 11, especially there is no air between the magnetic heating element 12 and the heat-conducting insulating component 11. When the magnetic heating element 12 generates heat, the heat is directly transferred to the heat-conducting insulating component 11 or transferred to the heat-conducting insulating component 11 through the reinforcing component 14, without the need for gas heat conduction (gas heat conduction speed is slow), thus accelerating the heat transfer speed.

[0052] It is understandable that in other embodiments, the heating assembly 10 may not be provided with the reinforcing component 14. When this embodiment is adopted, the magnetic heating element 12 may be fixedly connected to the heat-conducting insulating member 11 by other means.

[0053] In this embodiment, the reinforcing component 14 and the heat-conducting insulating component 11 are both made of ceramic material. The reinforcing component 14 and the heat-conducting insulating component 11 are both made of ceramic material. On the one hand, the heat conduction of the reinforcing component 14 can be achieved; on the other hand, the reinforcing component 14 and the heat-conducting insulating component 11 are made of the same material, which is conducive to the reinforcing component 14 and the heat-conducting insulating component 11 being constructed as an integrated structure.

[0054] In one embodiment, the magnetic heating element 12 is made of soft magnetic material, which has a high magnetic permeability, which is conducive to improving the conversion efficiency of electromagnetic induction between the magnetic field generating layer 13 and the magnetic heating element 12. The magnetic heating element 12 can be selected from one of a stainless steel heating element, a permalloy heating element, an iron metal heating element and a graphite heating element.

[0055] The magnetic heating element 12 can be arranged in any form in the accommodating cavity 111. In this embodiment, the magnetic heating element 12 is a heating wire. In other embodiments, the magnetic heating element 12 can be a heating sheet, a heating ring, etc.

[0056] The heating assembly 10 may further include a first electrode lead and a second electrode lead, and the first electrode lead and the second electrode lead may be connected to two ends of the magnetic field generating layer 13, respectively. Figure 3In this embodiment, the magnetic field generating layer 13 may include a first connection end 132 and a second connection end 133, and the first connection end 132 and the second connection end 133 may be two ends of the magnetic field generating layer 13 along the axial direction of the thermally conductive insulating member 11. The first electrode lead may be connected to the first connection end 132, and the second electrode lead may be connected to the second connection end 133.

[0057] In one embodiment, the first electrode lead and the second electrode lead can be respectively inserted into the heat-conducting insulating member 11, one end of the electrode lead is connected to the magnetic field generating layer 13, and the other end extends along the axial direction of the heat-conducting insulating member 11 to the outside of the accommodating cavity 111, and can extend to the end of the main body 112 away from the tip 113, for connecting to a power source. The magnetic heating element 12 is insulated from the first electrode lead and the second electrode lead.

[0058] In another embodiment, an insulating layer can be covered on the outer surface of the thermally conductive insulating member 11, and the magnetic field generating layer 13 is located between the thermally conductive insulating member 11 and the insulating layer. The first electrode lead and the second electrode lead can be respectively inserted into the insulating layer. One end of the electrode lead is connected to the magnetic field generating layer 13, and the other end extends along the insulating layer to an end of the main body 112 away from the tip 113 for connecting to a power source.

[0059] Wherein, the first electrode lead and the second electrode lead can both be silver wires.

[0061] The heating assembly 10 and atomizing device 100 provided in the present application are respectively provided with a magnetic field generating layer 13 and a magnetic heating element 12 on the outer surface of the heat-conducting insulating member 11 and a housing cavity 111. When a high-frequency alternating current is passed through the magnetic field generating layer 13, electromagnetic induction heating can be achieved, and the speed of electromagnetic induction heating is much greater than the speed of resistance heating, thereby effectively improving the heating efficiency. In addition, the magnetic field generating layer 13 is arranged on the outer surface of the heat-conducting insulating member 11, and the distance with the magnetic heating element 12 is close, which is conducive to improving the conversion efficiency of electromagnetic induction between the magnetic field generating layer 13 and the magnetic heating element 12. In addition, the heating assembly 10 provided in the present application is used to insert the inside of the aerosol generating matrix 200 to heat it.
