[0023] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0024] The heating module for an electronic cigarette and the electronic cigarette according to embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] 1 and 2 , an embodiment of the present application provides a heating module for an electronic cigarette. The heating module 100 includes:

[0026] Heating element 1;

[0027] A heat insulating member 2, the heat insulating member 2 being disposed around the outside of the heating body 1 and having a vacuum cavity therein;

[0028] The electromagnetic induction component 3 is wound around the side of the thermal insulation component 2 away from the heating body 1, so that the vacuum chamber is located between the electromagnetic induction component and the heating body. The electromagnetic induction component is used to apply a magnetic field to the heating body 1 when power is supplied. For example, the electromagnetic induction component can apply an alternating magnetic field to the heating body 1 when power is supplied.

[0029] Specifically, the heating body 1 may have a storage cavity for fixing cigarettes; when the electromagnetic induction component 3 applies an alternating magnetic field to the heating body 1, the heating body 1 is equivalent to cutting the magnetic flux lines in the alternating magnetic field, so that the heating body 1 can heat the cigarettes while generating heat.

[0030] The heating body 1 will generate a lot of heat when it is heated, and the thermal insulation member 2 is arranged between the heating body 1 and the electromagnetic induction member 3, and surrounds the heating body 1 inside the thermal insulation member 2. The vacuum cavity inside the thermal insulation member 2 can play the role of vacuum insulation, which can effectively block the heat generated by the heating body 1 from being transferred to the outside of the heating module, thereby avoiding the temperature of the surface of the heating module being too high.

[0031] Furthermore, the electromagnetic induction component 3 is placed around the outside of the heating body 1, and the thermal insulation component 2 is arranged between the heating body 1 and the electromagnetic induction component 3, so that the thermal insulation component 2 can also serve as a bracket for the electromagnetic induction component 3, thereby improving the structural compactness of the heating module, saving the setting space of the heating module, and helping to reduce the overall size of the heating module, thereby realizing the miniaturization of the heating module.

[0032] In addition, the heating body 1 is arranged inside the electromagnetic induction component 3, and the thermal insulation component 2 is arranged between the heating body 1 and the electromagnetic induction component 3, so that the thermal insulation component 2 is close to and tightly attached to the heating body 1, thereby improving the thermal insulation effect of the thermal insulation component 2 on the heating body 1.

[0033] The heating module 100 provided in the embodiment of the present application includes a heating body 1; a thermal insulation member 2, which is disposed around the outside of the heating body 1 and has a vacuum chamber therein; and an electromagnetic induction member 3, which is disposed around the side of the thermal insulation member 2 away from the heating body 1, such that the vacuum chamber is located between the electromagnetic induction member and the heating body, and the electromagnetic induction member is used to apply a magnetic field to the heating body 1 when power is applied. The thermal insulation member 2 is disposed between the heating body 1 and the electromagnetic induction member 3, so that the thermal insulation member 2 can serve as a support for the electromagnetic induction member 3 while providing insulation, thereby improving the structural compactness of the heating module and achieving miniaturization of the heating module.

[0034] Optionally, referring to FIG. 1 and FIG. 2 , the thermal insulation member 2 includes an outer wall 21 and an inner wall 22 , and the outer wall 21 and the inner wall 22 are relatively connected to form the vacuum cavity between the outer wall 21 and the inner wall 22 .

[0035] Specifically, the thermal insulation member 2 can be a vacuum tube or a vacuum plate. For example, when the thermal insulation member 2 is a vacuum tube, the thermal insulation member 2 is composed of an inner wall 22 of an inner tube structure and an outer wall 21 of an outer tube structure. The inner tube and the outer tube are tightly combined at both ends, and a vacuum is drawn between the inner tube and the outer tube to ensure the thermal insulation effect of the thermal insulation member 2.

[0036] In one embodiment, the outer wall 21 and the inner wall 22 may be connected by mutual welding or integrally formed.

[0037] In addition, the materials of the outer wall 21 and the inner wall 22 of the thermal insulation member 2 can be non-metallic materials such as ceramics, glass, and high-temperature resistant plastic materials, so as to prevent the thermal insulation member 2 from affecting electromagnetic induction when the thermal insulation member 2 is arranged between the heating body 1 and the electromagnetic induction member 3.

[0038] Specifically, the thermal insulation member 2 is made of ceramic, plastic, or glass. When the thermal insulation member 2 is ceramic, the structural strength of the thermal insulation member 2 is ensured, and even if the thermal insulation member 2 is placed inside the electromagnetic induction member 3, the influence of the thermal insulation member 2 on the magnetic field generated by the electromagnetic induction member 3 can be avoided. When the thermal insulation member 2 is plastic, the weight of the heating module can be reduced and the influence on the magnetic field distribution can also be avoided.

[0039] Optionally, referring to FIG. 3 , the electromagnetic induction component 3 includes a flexible substrate 31 and a circuit 32 . The circuit 32 is printed on the flexible substrate 31 to form an electromagnetic induction component with an FPC (Flexible Printed Circuit) structure.

[0040] Specifically, when the circuit 32 is printed on the flexible substrate 31, the flexible substrate 31 can provide a support carrier for the circuit 32, so that the electromagnetic induction component 3 has the ability to deform, and the electromagnetic induction component 3 can be tightly attached to the outside of the thermal insulation component 2, thereby improving the matching between the electromagnetic induction component 3 and the thermal insulation component 2.

[0041] Optionally, the electromagnetic induction component 3 is a coil wound on the thermal insulation component 2 .

[0042] Specifically, the coil can be a metal coil wound on the thermal insulation member 2. The coil can be a single-strand copper coil wound on the thermal insulation member 2, or a multi-strand copper coil wound on the thermal insulation member 2. It can also be a single-strand or multi-strand copper tape coil wound on the thermal insulation member 2, so as to improve the current flow efficiency in the electromagnetic induction member 3 and ensure the strength of the magnetic field formed by the electromagnetic induction member 3.

[0043] Optionally, the electromagnetic induction component 3 is coupled to the thermal insulation component 2 .

[0044] Specifically, the connection between the electromagnetic induction component 3 and the thermal insulation component 2 can be an electromagnetic induction component 3 with a circuit structure directly printed on the surface of the thermal insulation component 2, or an electromagnetic induction component 3 with a circuit structure directly deposited by metal on the surface of the thermal insulation component 2, thereby improving the tightness of the connection between the electromagnetic induction component 3 and the thermal insulation component 2, such as fusing the electromagnetic induction component 3 to the thermal insulation component 2 at the atomic level, eliminating the gap between the electromagnetic induction component 3 and the thermal insulation component 2, improving the strength of the electromagnetic induction component 3 combined with the thermal insulation component 2, and at the same time reducing the size of the heating module.

[0045] Optionally, the electromagnetic induction component 3 is formed on the thermal insulation component 2 through a metal deposition process.

[0046] Specifically, the electromagnetic induction component 3 can be an electromagnetic induction coil with a wire structure, such as a copper wire or a gold wire. The coil is formed on the outside of the thermal insulation component 2 through a metal deposition process, which can ensure the bonding strength between the electromagnetic induction component 3 and the thermal insulation component 2 and improve the stability of the power supply in the electromagnetic induction component 3.

[0047] Optionally, referring to FIG. 2 and FIG. 3 , the heating module further includes a heat insulating layer 4 , which is disposed between the heating body 1 and the heat insulating member 2 .

[0048] Specifically, the insulation material such as polystyrene board or glass fiber can be filled between the heating body 1 and the insulation member 2 to form the insulation layer 4. The insulation layer 4 is sandwiched between the heating body 1 and the insulation member 2, which can prevent the physical part of the insulation member 2 from transmitting heat to the outside, thereby reducing the temperature of the surface of the heating module.

[0049] Optionally, referring to FIG. 3 , the heating module further includes a shielding layer 5 , and the shielding layer 5 is disposed on a side of the electromagnetic induction component 3 away from the thermal insulation component 2 .

[0050] Specifically, a shielding layer 5 with an electromagnetic shielding effect is provided outside the electromagnetic induction component 3. The shielding layer 5 can prevent the magnetic field generated by the electromagnetic induction component 3 from being dispersed outwards, and can also prevent the magnetic field generated by the electromagnetic induction component 3 from affecting external electronic devices.

[0051] In addition, referring to Figures 1 and 2, the heating module also includes a shell 6, which is arranged on the side of the shielding layer 5 away from the electromagnetic induction component 3, that is, the shell 6 is located at the outermost side of the heating module to accommodate and protect the components inside the heating module.

[0052] Optionally, referring to FIG. 1 and FIG. 2 , the heating body 1 is in a circular tubular shape, and the heat insulating member 2 is disposed on the outer peripheral side of the heating body 1 .

[0053] Specifically, the heating body 1 can form a circular tubular vacuum tube with a cylindrical cavity in it, which can be used to fix the cigarette; the circular tubular heating body 1 can increase the contact area with the cigarette, which can not only improve the heating effect on the cigarette, but also ensure the uniformity of heating of the cigarette.

[0054] Optionally, the heating body 1 is a metal heating body.

[0055] Specifically, the heating element 1 can be a metal tube or metal plate made primarily of ferrite, such as low-carbon steel, iron-nickel alloy, or stainless steel. When the electromagnetic induction element 3 applies an alternating magnetic field to the heating element 1, the metal heating element 1 can cut the magnetic flux lines in the alternating magnetic field, allowing the heating element 1 to heat the cigarette while generating heat.

[0056] 4 and 5 , an embodiment of the present application provides an electronic cigarette, which includes a housing 101 and the heating module 100 ;

[0057] The heating module 100 is disposed in the housing 101 .

[0058] Specifically, the electronic cigarette may include a housing 101 , an upper bracket 102 , a lower bracket 103 , a circuit board 104 , a battery 105 and an upper cover 106 .

[0059] The heating module 100 is fixed in the outer shell 101 by the upper bracket 102 and the lower bracket 103. The leads of the heating module 100 are welded to the circuit board 104. The circuit board 104 and the battery 105 are fixed in the outer shell 101, and then the top opening of the outer shell 101 is sealed by the upper cover 106.

[0060] The user controls the entire electronic cigarette via the button cap. During use, the circuit board 104 regulates the temperature of the heating module 100 via leads. The battery 105 is connected to the circuit board 104 to provide energy for the entire electronic cigarette. The heating module 100 heats up quickly, and the circuit board 104 accurately controls the temperature, ensuring the stability of the electronic cigarette.
