Thus, the present application is not intended to be limited by the implementations shown, but is to be accorded the widest scope consistent with the principles and features presented.
[0040] Heat-not-burn is a technology that uses a special heating device to heat a special “cartridge” or “cigarette” to a low temperature to generate smoke, avoiding the generation of toxic and harmful substances by high-temperature combustion, while being able to experience close to the taste and flavor of a cigarette. However, the existing heating module often has the problems of large heat loss and low heating efficiency.
[0041] For this purpose, see Figures 1 to 5 The embodiment of the present application provides a heating module 100, which comprises an isolation structure 10, a heating element 20 and a heat insulation element 30. The isolation structure 10 has a through smoke passage 11 arranged along the length direction thereof, and the through smoke passage 11 is used for inserting a cigarette. The heating element 20 is sleeved on the isolation structure 10 and is used for heating the cigarette in the through smoke passage 11. The heat insulation element 30 is arranged outside the heating element 20.
[0042] It should be noted that the specific implementation form of the isolation structure 10 is not limited, which can adopt the form of an insulating film or an insulating tube, etc., and is not limited herein. The main function of the isolation structure 10 is to isolate the heating element 20 and the cigarette in the through smoke passage 11, to avoid the damage of the heating element 20 caused by the pulling action of the cigarette, and in some embodiments, the isolation structure 10 can also play the role of heat conduction and heat equalization.
[0043] The specific implementation of the heating element 20 is not limited. It can be a heating element that can generate heat itself, such as a resistance wire, a carbon fiber heating plate, etc. It is not limited here. It can also be an electromagnetic generator, such as an antenna 21, an electromagnetic transmitter, etc., to heat the cigarette through electromagnetic or microwave means, etc. It is not limited here.
[0044] The specific implementation of the heat insulation component 30 is not limited. It can be a heat insulation film made of heat insulation material, such as a PI film (polyimide film), which has good thermal conductivity, insulation, adhesion and radiation resistance, and can be used for a long time within the temperature range of the smoking device. It can also be an aerogel component, etc., and is not limited here.
[0045] In this embodiment of the application, by setting the isolation structure 10, the heating element 20 can be isolated, preventing the heating element 20 from being damaged by the pulling action of the cigarette. By setting the heat insulation element 30, the heat generated by the heating element 20 can be prevented from dissipating, reducing heat loss and improving heating efficiency.
[0046] In some embodiments, both the isolation structure 10 and the heat insulation element 30 are formed by rolling PI film, and the thickness of the heat insulation element 30 is greater than the thickness of the isolation structure 10. By making the thickness of the heat insulation element 30 thicker, it can have better heat insulation performance, concentrate heat in the smoke passage 11 to heat the cigarette, and reduce heat loss. On the other hand, making the isolation structure 10 thinner can reduce heat loss when the heating element 20 transfers heat to the smoke passage 11. Alternatively, the overall mass of the heating module 100 can be reduced, thereby allowing the heating module 100 to heat up faster.
[0047] Please see Figure 1 As shown in Figure 4, in some embodiments, the heating element 20 includes an antenna 21, the isolation structure 10 includes an isolation membrane 12, the antenna 21 is used to transmit high-frequency electromagnetic waves, the inner side of the isolation membrane 12 is rolled to form the smoke passage 11, and the antenna 21 is wound around the outer side of the isolation membrane 12.
[0048] In the technical solution of the embodiment, the antenna 21 is used to emit high-frequency electromagnetic waves. The high-frequency electromagnetic waves cause the water molecules in the heated object to vibrate violently in the microwave high-frequency electromagnetic field. The molecular friction is converted into heat energy to heat the object. Any object containing water molecules can be heated. Compared with the self-heating method, it does not require the use of metal tubes for heat conduction and transfer, resulting in less heat loss, higher heating efficiency, and faster heating speed.
[0049] And, the specific implementation form of the isolation film 12 is not limited, can be using PI film, also can be using TPI film and so on, in an embodiment, the isolation film 12 is PI film, can play the role of insulation, protection antenna 21, prevent short circuit, and PI film has excellent heat insulation effect, can also prevent the change of resistance caused by high temperature oxidation of antenna 21 (metal), influence the efficiency of antenna 21, protect the radio frequency antenna 21 from corrosion, and the inner surface of PI film is smooth, easy to clean.PI film is very thin, its thickness range is generally between 0.01mm to 0.1mm, dielectric constant is low, about 4, microwave penetration loss is small, heating efficiency is high.
[0050] In a further embodiment, the isolation structure 10 only includes a layer of the PI film, and the heat insulation piece 30 includes at least three layers of the PI film.
[0051] More specifically, in some embodiments, the heating module 100 further includes a power supply, a control device and a microwave chip, the microwave chip is electrically connected between the antenna 21, the control device is electrically connected between the power supply and the microwave chip, direct current to microwave conversion is realized through the microwave chip, so that the antenna 21 emits microwave to realize heating of the cigarette in the smoke passage 11.
[0052] Of course, in further embodiments, a temperature sensor is arranged in the smoke passage 11 to sample temperature, process data, and the control device adaptively generates PWM modulated microwave chip voltage to realize microwave pulse power output, so that the temperature in the smoke passage 11 is controllable.
[0053] And the specific shape of the antenna 21 is not limited, can be round tower type, can also be ring type, etc., which is not limited here, in an embodiment, the antenna 21 is spiral type, so arranged, the electromagnetic wave field formed by the spiral antenna 21 can heat the object without interval for 360 degrees, and the object is heated uniformly.
[0054] In addition, the antenna 21 arranged in spiral shape can be directly sleeved on the isolation structure 10 from top to bottom during installation, so as to simplify the installation process.
[0055] And, specifically, the spiral antenna 21 is formed by bending a root antenna 21 along spiral, which has a certain stability. It should be emphasized that in some embodiments, the isolation structure 10 only includes a layer of heat insulation film, which is soft and not easy to stand alone, at this time, since the antenna 21 is spiral, spiral has stability, so as to play a supporting role to the isolation film 12 and make it stand up.
[0056] Of course, the cross-sectional shape of the antenna 21 is not limited to a cylindrical shape, and can be a rectangular shape, i.e., the antenna 21 is in a sheet shape. When the antenna 21 is in a sheet shape, the uniformity of the magnetic field lines of the emitted magnetic field is better.
[0057] To prevent the leakage of the microwaves emitted by the antenna 21, in some embodiments, the heating module 100 further comprises a shielding member 40 located outside the antenna 21 to block the outward diffusion of the electromagnetic waves emitted by the antenna 21.
[0058] In actual use, the shielding member 40 can reflect the microwaves emitted by the antenna 21, and is located outside the antenna 21, so that the microwaves can be reflected towards the smoke passage 11, and the microwaves can be concentrated in the smoke passage 11 to heat the cigarettes.
[0059] Specifically, the shielding member 40 can be made of a metal material, and more specifically, the length of the shielding member 40 can be longer than the length of the emitting part of the antenna 21, so that the microwaves emitted by the antenna 21 can be better reflected, and the leakage of the microwaves can be avoided.
[0060] Of course, the shielding member 40 can also be grounded nearby, so that the interference of the microwaves can be further reduced.
[0061] In some embodiments, the heating module 100 further comprises a support assembly 50, which comprises a first support member 51 and a second support member 52 arranged at both ends of the heat insulation member 30 in the length direction; the first support member 51 and the second support member 52 are both provided with an annular protrusion 53 for limiting the outer side of the heat insulation member 30.
[0062] According to the technical solution of the present embodiment, by arranging the support assembly 50, the outer side of the heat insulation member 30 can be limited, and since the heat insulation member 30, the heating member 20 and the isolation structure 10 are nested inside and outside, the heating member 20 and the isolation structure 10 can also be limited when the heat insulation member 30 is limited, so that the positioning and installation of the heat insulation member 30, the heating member 20 and the isolation structure 10 can be realized.
[0063] It should be noted that the existing heating module 100 is generally provided with a metal heat conduction pipe, and the heating element 20 and the isolation structure 10 are generally supported by the metal heat conduction pipe. Therefore, when the metal heat conduction pipe transmits support force to the heating element 20, the isolation structure 10 needs to transmit force, so that the heating element 20 and the isolation structure 10 may move relatively under long-term transmission of support, thereby affecting the long-term stability of the heating module 100.
[0064] In the scheme of the embodiment, the second support 52 is provided with a via hole for the wire harness of the antenna 21 to pass through, and the second support 52 is used to support the antenna 21, so that the antenna 21 is directly supported by the second support 52, without the need for the isolation structure 10 to transmit support force, thereby improving the long-term stability of the heating module 100.
[0065] The first support 51 and the second support 52 can jointly support the isolation structure 10, the heating element 20 and the heat insulation element 30. In addition, a connecting structure can be provided on the first support 51 and the second support 52 to realize connection of other components, such as connection with a mouthpiece.
[0066] In addition, in order to further improve the heat insulation effect, the annular protrusion 53 has a first side and a second side arranged opposite in the radial direction of the smoke passage 11. The first side is used to limit the outer side of the heat insulation element 30. The shielding element 40 is in abutment with the second side of the annular protrusion 53 and is spaced apart from the heat insulation element 30 in the radial direction of the smoke passage 11 to define a heat insulation cavity 533 together with the heat insulation element 30.
[0067] In the embodiment of the present application, the shielding element 40 and the heat insulation element 30 are spaced apart in the radial direction of the smoke passage 11 to form the heat insulation cavity 533, which can effectively reduce the heat transfer between the heat insulation element 30 and the shielding element 40, thereby effectively reducing heat loss and improving heating efficiency.
[0068] In summary, compared with the heating type heating mode, in the embodiment, heating is performed by selecting the antenna 21, so that the metal pipe for heat conduction and heat distribution can be omitted, the heat loss in the transmission process is reduced, and since the metal pipe is omitted, the overall mass of the heating module 100 can be reduced, the heating rate of the heating module 100 is faster, and it is emphasized that in actual use, a part of the smoke passage 11 can constitute a resonant cavity, and the microwave to heat conversion is realized through the resonant cavity, and the antenna 21 in the application is arranged on the outside of the isolation structure 10 and is not located in the resonant cavity, so that.
[0069] Of course, please refer to Figures 5 to 9 In some embodiments, the heating piece 20 includes a resistance sheet 22, the isolation structure 10 includes a heat pipe 13 and an isolation film 12, the smoke passage 11 is formed on the inside of the heat pipe 13, and the isolation film 12 is arranged on the outside of the heat pipe 13.
[0070] Corresponding to the technical solution in the embodiment, by arranging the heating sheet as a resistance sheet 22, after the resistance sheet 22 is powered on, the temperature of the resistance sheet 22 itself rises, and then the heat is transmitted to the heat pipe 13, and after being evenly heated by the heat pipe 13, it is transmitted to the smoke passage 11, thereby heating the cigarette in the smoke passage 11.
[0071] It should be noted that since the heat pipe 13 needs to have excellent heat transfer and heat distribution effect, the heat pipe 13 is generally made of metal material, for example, made of copper foil or aluminum foil, and copper and aluminum have excellent electrical conductivity. If the isolation film 12 is not arranged, the resistance sheet 22 is easy to be short-circuited, therefore, by arranging the isolation film 12, the resistance sheet 22 and the heat pipe 13 can be isolated, and the resistance sheet 22 is prevented from being short-circuited by the heat pipe 13. Specifically, the isolation film 12 can be made of insulating material, for example, made of PI film. The PI film has excellent insulation performance, and the thickness of the PI film is thin, which can be 0.1-0.01mm, thereby avoiding more heat loss in the process of transmitting heat energy.
[0072] In addition, the thickness or mass of the heat pipe 13 cannot be too large, otherwise, in the heating process, the heating pipe needs to be heated to a preset temperature, and if the thickness or mass of the heat pipe 13 is too large, more heat needs to be consumed in the heating process, thereby causing large heat loss. Therefore, in some embodiments, the thickness of the heat pipe 13 is less than 2mm, so that the thickness of the heat pipe 13 is thin enough, and the heat generated by the resistance sheet 22 is more easily transmitted from the heat pipe 13 to the cigarette.
[0073] And the mass of the heat pipe 13 is less than 5g, so that in the process of heating the heat pipe 13, the required heat is less, the heat pipe 13 is easy to heat to the preset temperature, and the heat loss is small.
[0074] And the cross-sectional shape of the resistance wire of the resistance sheet 22 is not limited, which can be in the form of a sheet or in the form of a strip, which is not limited here.
[0075] Specifically, please refer to Figure 8 Corresponding to this embodiment, the cross-sectional shape of the resistance wire of the resistance sheet 22 is cylindrical, of course, please refer to Figure 9 Corresponding to this embodiment, the resistance wire of the resistance sheet 22 is in the form of a strip.

The heating module 100 adopts one or all of the technical solutions of the foregoing embodiments, and thus has the technical advantages of the foregoing embodiments.
