Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection required by the present application.

[0063] Referring to Figures 1 to 6 As shown in the utility model embodiment, the low-temperature non-combustible cigarette A comprises a herbal product 9 and at least one ceramic induction heating element 31, and the ceramic induction heating element 31 is arranged in the herbal product 9. The ceramic induction heating element 31 has electromagnetic properties, is used for generating an induced current, and transmits heat generated by the induced current to the herbal product 9, so as to heat and atomize the herbal product 9.

[0064] In the embodiment, referring to Figures 10 to 12 As shown in the utility model embodiment, when the low-temperature non-combustible cigarette A is put into the heating bin 21 of the heating non-combustible device 10, the ceramic induction heating element 31 arranged in the herbal product 9 is electromagnetically coupled with the energized induction coil 4 arranged in the heating non-combustible device 10. It should be noted that the electromagnetic coupling between the ceramic induction heating element 31 and the energized induction coil 4 means that when the induction coil 4 generates a changing current due to energization, a changing magnetic field is generated around the induction coil 4, and the ceramic induction heating element 31 generates an induced current due to the induction of the changing magnetic field. Then the ceramic induction heating element 31 transmits heat generated by the induced current to the herbal product 9 in a heat conduction manner, so as to heat and atomize the herbal product 9.

[0065] It should be further noted that the above-mentioned herbal product 9 can be a low-temperature non-combustible tobacco product, can also be a herbal substance (such as mugwort), and can also be other types of aerosol generating products, such as tobacco leaves, tobacco shreds, etc., which can be determined according to the actual use requirements of users, and the embodiment does not make specific limitations thereon. The so-called low-temperature non-combustible tobacco product mainly refers to an aerosol generating product made of tobacco shreds, tobacco particles, plant fragments, tobacco flavor, propylene glycol, etc., and under low-temperature heating conditions, nicotine and other flavoring substances inside the tobacco product can be volatilized without generating solid particles, only generating atomized steam. The low-temperature non-combustion is actually a low-temperature dry distillation process, and the heating temperature is generally 200℃-400℃, and the low temperature here refers to a temperature in the range of 200℃-400℃.

[0066] As described above, in the technical solution of the embodiment, at least one ceramic induction heating element 31 with electromagnetic properties is arranged in the herbal product 9 of the low-temperature non-combustible cigarette A, the ceramic induction heating element 31 is used for generating an induced current, and transmits heat generated by the induced current to the herbal product 9, so as to heat and atomize the herbal product 9. In this way, compared with the induction heating element made of a full-metal magnetic material, since the ceramic induction heating element 31 in the embodiment of the application is made of more environmentally friendly ceramic material, the pollution caused by the ceramic induction heating element 31 to the environment after being discarded together with the used herbal product 9 can be reduced.

[0067] In addition, since the ceramic induction heating piece 31 is directly arranged in the herbal product 9 instead of being inserted into the herbal product 9, the ceramic induction heating piece 31 does not damage the internal structure of the herbal product 9, and after the herbal product 9 is heated and atomized, the ceramic induction heating piece 31 also does not need to be pulled out of the herbal product 9, which can prevent the tobacco ash generated after the herbal product 9 is heated and atomized from falling into the heating chamber 21 of the heat-not-burn device 10 when the ceramic induction heating piece 31 is pulled out of the herbal product 9, thereby causing the problem of difficulty in cleaning the heat-not-burn device 10.

[0068] Further, in the present embodiment, the ceramic induction heating piece 31 can be a first ceramic induction heating piece 311 in a sheet shape, a column shape, a thick block shape, or an irregular shape, Figure 2 and Figure 3 A first ceramic induction heating piece 311 in a column shape is shown, Figure 4 A first ceramic induction heating piece 311 in a sheet shape is shown. Alternatively, as Figure 5 shown, the ceramic induction heating piece 31 can also be a second ceramic induction heating piece 312 in a granular shape or a broken block shape.

[0069] Further, in some embodiments, as Figure 2 shown, when at least one first ceramic induction heating piece 311 in a column shape is embedded in the low-temperature heat-not-burn cigarette A, the first ceramic induction heating piece 311 can extend obliquely from one end to the other end in the herbal product 9.

[0070] In other embodiments, as Figure 3 shown, when at least one first ceramic induction heating piece 311 in a column shape is embedded in the low-temperature heat-not-burn cigarette A, the first ceramic induction heating piece 311 can extend from one end to the other end in the herbal product 9 along the axial direction of the herbal product 9. Compared to the arrangement mode in which the first ceramic induction heating piece 311 extends obliquely from one end to the other end in the herbal product 9 in the above-mentioned embodiment, in the present embodiment, the first ceramic induction heating piece 311 extends from one end to the other end in the herbal product 9 along the axial direction of the herbal product 9, and the heat generated by the induction current of the first ceramic induction heating piece 311 itself can be more uniformly transmitted to the herbal product 9, thereby being able to more uniformly heat and atomize the herbal product 9.

[0071] In other embodiments, as Figure 4As shown, when the shape of the first ceramic induction heating piece 311 is sheet-shaped, compared with the first ceramic induction heating piece 311 in a columnar shape, since the surface area of the first ceramic induction heating piece 311 in a sheet shape is larger than that of the first ceramic induction heating piece 311 in a columnar shape, the contact area between the first ceramic induction heating piece 311 in a sheet shape and the herbal product 9 is larger than that between the first ceramic induction heating piece 311 in a columnar shape and the herbal product 9. Thus, when the shape of the first ceramic induction heating piece 311 is sheet-shaped, the contact area between the first ceramic induction heating piece 311 and the herbal product 9 can be increased, i.e., the heating area of the first ceramic induction heating piece 311 can be increased, so that the atomized herbal product 9 can be heated more quickly, more sufficiently and more uniformly, and the smoking experience and smoking taste of the user can be improved.

[0072] In other embodiments, when the shape of the first ceramic induction heating piece 311 is irregular, the irregular shape in the present embodiment can be a combination structure of a wavy shape, an arc shape and a triangular shape, a combination structure of a sawtooth shape and a columnar shape, etc., which is not limited here.

[0073] Further, in some embodiments, as shown in FIG. 6, the low-temperature non-combustible cigarette A can further comprise a second ceramic induction heating piece 312 in a granular or broken block shape, which is embedded in the herbal product 9. Figure 5 As shown, when the low-temperature non-combustible cigarette A is embedded with a plurality of second ceramic induction heating pieces 312 in a granular or broken block shape, the plurality of second ceramic induction heating pieces 312 are dispersed and unevenly distributed in the herbal product 9. Compared with the scheme of embedding the first ceramic induction heating piece 311 in a columnar shape in the herbal product 9, the second ceramic induction heating piece 312 in the present embodiment is dispersed and unevenly distributed in the herbal product 9, so that the second ceramic induction heating piece 312 can be more dispersedly arranged in each region of the herbal product 9, so that the heat generated by the second ceramic induction heating piece 312 due to the induced current can be more uniformly transmitted to each region of the herbal product 9, thereby achieving the effect of more uniformly heating the atomized herbal product 9.

[0074] In other embodiments, when the low-temperature non-combustible cigarette A is embedded with a plurality of second ceramic induction heating pieces 312 in a granular or broken block shape, the plurality of second ceramic induction heating pieces 312 are dispersed and evenly distributed in the herbal product 9. Compared with the second ceramic induction heating piece 312 dispersed and unevenly distributed in the herbal product 9 in the above embodiment, the second ceramic induction heating piece 312 in the present embodiment can be more uniformly arranged in each region of the herbal product 9, so that the second ceramic induction heating piece 312 in the present embodiment can further and uniformly heat the atomized herbal product 9.

[0075] Further, the low-temperature non-combustible cigarette A is embedded with at least one first ceramic induction heating piece 311 in a sheet shape, a columnar shape, a thick block shape or an irregular shape, and further embedded with a plurality of second ceramic induction heating pieces 312 in a granular or broken block shape. For example, as shown in FIG. 7, the low-temperature non-combustible cigarette A can further comprise a second ceramic induction heating piece 312 in a granular or broken block shape, which is embedded in the herbal product 9.Figure 6 As shown, the low-temperature non-combustible cigarette A is internally embedded with a columnar first ceramic induction heating element 311 and a plurality of granular or blocky second ceramic induction heating elements 312. In this way, by internally embedding at least one first ceramic induction heating element 311 and a plurality of second ceramic induction heating elements 312 in the low-temperature non-combustible cigarette A, the heat generated by the first ceramic induction heating element 311 and the second ceramic induction heating element 312 in a unit of time can be increased, the atomized herbal product 9 can be heated more quickly and efficiently, and the user's smoking experience and smoking taste can be improved.

[0076] Further, in specific implementation, the ceramic induction heating element 31 can be made in the following ways:

[0077] In some embodiments, as Figure 7 As shown, the ceramic induction heating element 31 can be made by mixing at least one magnetizable conductive metal substance 200 and an electrically insulating ceramic substance 100. Specifically, the magnetizable conductive metal substance 200 can include at least any one of iron, nickel, cobalt, and alloys thereof, which are not specifically limited here. The "alloy" mentioned above can be iron-nickel alloy, iron-cobalt alloy, nickel-cobalt alloy, or iron-nickel-cobalt alloy, which are not specifically limited here. In this way, when the ceramic induction heating element 31 is doped with the above-mentioned at least one magnetizable conductive metal substance 200, the ceramic induction heating element 31 has electromagnetic properties, so that the ceramic induction heating element 31 can generate an induced current by electromagnetic coupling with the energized induction coil 4 provided in the heating non-combustible device 10, and transfer the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0078] In addition, by using the ceramic induction heating element 31 doped with at least one magnetizable conductive metal substance 200, compared with a heating body without electromagnetic properties, the ceramic induction heating element 31 of the present embodiment can quickly form a stronger current eddy current in itself due to electromagnetic induction, thereby increasing the heat generated by the ceramic induction heating element 31 in a unit of time, more quickly and efficiently heating and atomizing the herbal product 9, and improving the user's smoking experience and smoking taste.

[0079] In this embodiment, the ceramic induction heating element 31 can be made by mixing a magnetizable conductive metal material 200 and an electrically insulating ceramic material 100. For example, the ceramic induction heating element 31 is made by mixing iron and an electrically insulating ceramic material. Of course, the ceramic induction heating element 31 can also be made by mixing two or more magnetizable conductive metal materials 200 and electrically insulating ceramic materials 100. For example, the ceramic induction heating element 31 is made by mixing iron, nickel, and an electrically insulating ceramic material 100. For example, in some application scenarios of this embodiment, when the content of the magnetizable conductive metal material 200 doped in the ceramic induction heating element 31 is low, the same type of magnetizable conductive metal material 200 can be doped into the ceramic induction heating element 31, or different types of magnetizable conductive metal materials 200 can be doped into the ceramic induction heating element 31 to increase the electromagnetic properties of the ceramic induction heating element 31. This allows the ceramic induction heating element 31 to generate a sufficiently large induced current due to the changing magnetic field generated by the induction coil 4, thereby generating enough heat to heat and atomize the herbal product 9, making the atomization of the herbal product 9 more complete.

[0080] In other embodiments, such as Figure 8 As shown, the ceramic induction heating element 31 can also be made of a mixture of a non-magnetizable conductive metal material 300, an electrically insulating ceramic material 100, and a magnetic material 400. Specifically, the non-magnetizable conductive metal material 300 can include at least one of copper, aluminum, zinc, lead, tin, platinum, and their alloys, wherein the aforementioned "alloy" can be a copper-aluminum alloy, a copper-zinc alloy, a copper-lead alloy, an aluminum-zinc alloy, etc., and is not specifically limited here. The magnetic material 400 can include at least one of neodymium iron boron, samarium cobalt, or iron, nickel, cobalt, and their alloys, wherein the aforementioned "alloy" can be an iron-nickel alloy, an iron-cobalt alloy, a nickel-cobalt alloy, or an iron-nickel-cobalt alloy.

[0081] Thus, when the ceramic induction heating element 31 is doped with a non-magnetized conductive metal material 300 and a magnetic material 400, the ceramic induction heating element 31 becomes electromagnetic. In this way, the ceramic induction heating element 31 can generate an induced current by electromagnetically coupling with the energized induction coil 4 installed in the heating non-combustible device 10, and transfer the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0082] Furthermore, by using a ceramic induction heating element 31 doped with a non-magnetic conductive metal material 300 and a magnetic material 400, compared to a heating element that is not electromagnetic, the ceramic induction heating element 31 of this application embodiment can also rapidly generate a stronger current eddy current within itself due to electromagnetic induction, thereby increasing the heat generated by the ceramic induction heating element 31 per unit time, heating the atomized herbal product 9 more quickly and efficiently, and improving the user's inhalation experience and inhalation taste.

[0083] In yet some embodiments, as shown in Figure 9 semiconductor substance 500 can include any one of carbon, silicon, germanium, gallium arsenide, indium phosphide, silicon carbide and gallium nitride, which are not limited specifically herein. The magnetic substance 400 can include any one of neodymium iron boron, samarium cobalt, iron, nickel, cobalt and alloys thereof, wherein the "alloy" can be iron-nickel alloy, iron-cobalt alloy, nickel-cobalt alloy or iron-nickel-cobalt alloy, which are not limited specifically herein. In this way, when the ceramic induction heating piece 31 is doped with the above-mentioned semiconductor substance 500 and magnetic substance 400, the ceramic induction heating piece 31 has electromagnetic properties, so that the ceramic induction heating piece 31 can generate an induced current by electromagnetic coupling with the energized induction coil 4 provided in the heat-not-burn device 10, and transfer the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0084] Referring to Figures 10 to 12 The utility model embodiment further provides a heat-not-burn device 10 for heating and atomizing the low-temperature non-combustible cigarette A in any of the above-mentioned embodiments. The heat-not-burn device 10 comprises a shell 1, a sleeve 2, an induction coil 4, a temperature measuring piece 33 and a control piece 5. The shell 1 is provided with an opening 11 for placing the herbal product 9 to be heated and atomized. The sleeve 2 is arranged in the shell 1, and the sleeve 2 is provided with a heating chamber 21 communicating with the opening 11, and the heating chamber 21 is used for placing the herbal product 9. The induction coil 4 is arranged in the shell 1, and the induction coil 4 is arranged around the outside of the sleeve 2 along the axial direction of the sleeve 2. When the herbal product 9 is placed in the heating chamber 21, the ceramic induction heating piece 31 arranged in the herbal product 9 generates an induced current by electromagnetic coupling with the energized induction coil 4, and transfers the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9. The temperature measuring piece 33 is arranged in the shell 1, and is used for detecting the heating temperature of the ceramic induction heating piece 31. The control piece 5 is arranged in the shell 1, and the control piece 5 is electrically connected with the induction coil 4 and the temperature measuring piece 33 respectively.

[0085] In this embodiment, the electromagnetic coupling between the ceramic induction heating element 31 and the energized induction coil 4 means that when the induction coil 4 generates a changing current due to energization, a changing magnetic field is generated within the intermediate region formed by the induction coil 4 itself and the surrounding sleeve 2 (i.e., inside the induction coil 4). The ceramic induction heating element 31, located inside the herbal product 9, generates an induced current due to the sensing of this changing magnetic field. It should be noted that the current through the induction coil 4 can be an alternating current or a changing direct current, as long as it can cause the induction coil 4 to generate a changing current and thus a changing magnetic field. This embodiment does not impose any specific limitations.

[0086] It should be noted that the induction coil 4 is arranged to be wound around the outside of the sleeve 2 along the axial direction of the sleeve 2, which can be configured such that the induction coil 4 is fixed to the outer peripheral wall of the sleeve 2 along the axial direction of the sleeve 2 (e.g., Figure 12 As shown in the figure, the induction coil 4 can also be arranged along the axial direction of the sleeve 2, with the induction coil 4 spaced apart from the outer peripheral wall of the sleeve 2. For example, in this embodiment, a fixed bracket (not shown) can be fitted on the outer peripheral wall of the sleeve 2, and then the induction coil 4 can be installed and fixed on the fixed bracket along the axial direction of the sleeve 2 to make the installation of the induction coil 4 more stable. As long as the usage requirements are met, the specific requirements are not limited here.

[0087] In this embodiment, during the heating and atomization of the herbal product 9, the temperature measuring element 33 detects the heating temperature of the ceramic induction heating element 31 and sends the detected heating temperature of the ceramic induction heating element 31 to the control element 5 in the form of an electrical signal. The control element 5 controls the temperature of the ceramic induction heating element 31 based on the received heating temperature. Specifically, in this embodiment, assuming that the temperature range required for the atomization of the herbal product 9 is a target temperature range, when the heating temperature of the ceramic induction heating element 31 is outside this target temperature range, the control element 5 controls the temperature of the ceramic induction heating element 31 until the heating temperature of the ceramic induction heating element 31 rises or falls back to the target temperature range, at which point the control element 5 stops controlling the temperature of the ceramic induction heating element 31. Specifically, the control element 5 controls the temperature of the ceramic induction heating element 31 in ways including, but not limited to, adjusting the output power of the induction coil 4 to adjust the strength of the magnetic field, thereby adjusting the heating temperature of the ceramic induction heating element 31.

[0088] More specifically, when the heating temperature of the ceramic induction heating piece 31 is greater than the maximum value in the target temperature range, the control piece 5 can weaken the strength of the magnetic field generated by the induction coil 4 by reducing the output power of the induction coil 4, so as to reduce the heating temperature of the ceramic induction heating piece 31, until the heating temperature of the ceramic induction heating piece 31 is reduced to the target temperature range, the control piece 5 stops the temperature control operation on the ceramic induction heating piece 31 and maintains the output power of the induction coil 4 at the moment. When the heating temperature of the ceramic induction heating piece 31 is less than the minimum value in the target temperature range, the control piece 5 can strengthen the strength of the magnetic field generated by the induction coil 4 by increasing the output power of the induction coil 4, so as to increase the heating temperature of the ceramic induction heating piece 31, until the heating temperature of the ceramic induction heating piece 31 rises to the target temperature range, the control piece 5 stops the temperature control operation on the ceramic induction heating piece 31 and maintains the output power of the induction coil 4 at the moment.

[0089] As described above, in the technical solution of the present embodiment, by arranging the control piece 5 and the temperature measuring piece 33 electrically connected with the control piece 5, the heating temperature of the ceramic induction heating piece 31 can be controlled within the temperature range required for the aerosol generation of the herbal product 9, thereby being conducive to avoiding the burning of the herbal product 9 and the generation of the burnt smell due to the heating temperature of the ceramic induction heating piece 31 being higher than the aerosol generation temperature required by the herbal product 9, and being conducive to avoiding the insufficient aerosol generation of the herbal product 9 due to the heating temperature of the ceramic induction heating piece 31 being lower than the aerosol generation temperature required by the herbal product 9, thereby causing the waste of the herbal product 9 and affecting the user's smoking taste. Thus, the present technical solution is conducive to improving the user's smoking taste and reducing the waste of the herbal product 9.

[0090] Further, in some embodiments, the temperature measuring piece 33 can be a non-magnetic temperature sensor. The above-mentioned "non-magnetic temperature sensor" refers to a temperature sensor that does not exhibit magnetic properties in an external magnetic field, i.e., the non-magnetic temperature sensor will not be electrically heated by generating an induced current in a changing magnetic field.

[0091] Since the temperature measuring piece 33 is a non-magnetic temperature sensor, the temperature measuring piece 33 will not be electrically heated by generating an induced current in the changing magnetic field generated by the induction coil 4, i.e., the temperature measuring piece 33 itself will not generate heat, so as to avoid the temperature measuring piece 33 affecting the accuracy of the temperature measurement result due to the heat generated by itself. That is, the adoption of the non-magnetic temperature sensor as the temperature measuring piece 33 in the present embodiment can improve the accuracy of the temperature measurement result.

[0092] In the embodiment, the non-magnetic temperature sensor can be a platinum resistance temperature sensor or a thermocouple temperature sensor. The platinum resistance temperature sensor is made of platinum, which is a non-magnetic material. The thermocouple temperature sensor works as follows: two conductors of different materials form a closed loop, i.e., a thermocouple. When there is a temperature gradient between the two ends of the thermocouple, an electric current will flow in the closed loop, and a thermoelectric potential will exist between the two ends of the thermocouple. Therefore, when the material composition of the thermocouple is determined, the magnitude of the thermoelectric potential is irrelevant to the action of the changing magnetic field generated by the induction coil 4, the length and diameter of the thermocouple, and is only related to the temperature difference between the two ends of the thermocouple. Therefore, the thermocouple temperature sensor will not generate heat in the changing magnetic field generated by the induction coil 4, so as to avoid affecting the accuracy of the temperature measurement result.

[0093] Of course, the non-magnetic temperature sensor in the embodiment can also be other temperature sensors that will not generate induced current and be electrically heated in a changing magnetic field, which are not limited here.

[0094] Further, in other embodiments, the temperature measuring member 33 can also be a magnetic temperature sensor. In the embodiment, the magnetic temperature sensor can be a magnetic sensitive resistance temperature sensor or a ferromagnetic temperature sensor. Of course, the magnetic temperature sensor in the embodiment can also be other magnetic temperature sensors, which are not limited here.

[0095] Further, when the temperature measuring member 33 is a magnetic temperature sensor, since the magnetic temperature sensor will generate induced current and be electrically heated in a changing magnetic field, the temperature measuring member 33 should be arranged outside the magnetic field generated by the induction coil 4, or in a position where the magnetic field strength is as weak as possible, for example, the temperature measuring member 33 can be arranged outside the space surrounded by the induction coil 4. Correspondingly, the temperature measuring member 33 will not generate induced current when the magnetic field strength is zero, so as to not generate heat and cause inaccurate measurement of the temperature measuring member 33, or the temperature measuring member 33 generates less induced current in a magnetic field region with weak magnetic field strength, and the heat generated by the induced current is also small and can be ignored, so as to reduce the influence of the heat generated by the temperature measuring member 33 on the accuracy of the temperature measurement result.

[0096] Specifically, when the temperature measuring member 33 is a magnetic temperature sensor, the temperature measuring member 33 can have the following arrangement modes:

[0097] The first arrangement mode is as follows: Figure 12As shown, the temperature measuring element 33 is mounted on the outer peripheral wall of the sleeve 2 at the end away from the opening 11, and the temperature measuring element 33 is located outside the space surrounding the induction coil 4. In this case, since the temperature measuring element 33 is not in direct contact with the ceramic induction heating element 31, there will be a deviation between the temperature detected by the temperature measuring element 33 and the actual heating temperature of the ceramic induction heating element 31. In this embodiment, in order to enable the temperature measuring element 33 to accurately detect the actual heating temperature of the ceramic induction heating element 31, temperature compensation can be performed on the temperature measuring element 33. For example, a compensation temperature can be set first, and then the value obtained by adding the temperature detected by the temperature measuring element 33 to the compensation temperature can be used as the actual heating temperature of the ceramic induction heating element 31. In this way, the actual heating temperature of the ceramic induction heating element 31 can be obtained quickly and accurately, which is beneficial for the control element 5 to accurately control the temperature of the ceramic induction heating element 31.

[0098] In the second configuration, the temperature measuring element 33 is mounted on the inner peripheral wall of the sleeve 2 at the end away from the opening 11, and the temperature measuring element 33 is located outside the space surrounding the induction coil 4 (not shown). Since the temperature measuring element 33 does not directly contact the ceramic induction heating element 31, temperature compensation is also required for the temperature measuring element 33 in this embodiment. The details of temperature compensation will not be elaborated here.

[0099] Furthermore, when the temperature measuring element 33 is a non-magnetic temperature sensor, it can be installed at any position on the sleeve 2. However, since the temperature measuring element 33 is not in direct contact with the ceramic induction heating element 31 located inside the herbal product 9, temperature compensation is also required for the temperature measuring element 33 in this embodiment. The details of temperature compensation will not be elaborated here.

[0100] like Figure 11 and Figure 12 As shown, a heat insulation layer 8 is provided between the inner wall of the outer shell 1 and the induction coil 4. The heat insulation layer 8 is used to block the heat generated by the ceramic induction heating element 31 from being conducted to the outer shell 1, thereby preventing the outer shell 1 from becoming too hot to touch and reducing heat loss, so that more heat can be used to heat the herbal product 9, thereby reducing the energy consumption of the heating non-combustible device 10.

[0101] Optionally, in this embodiment, the heat insulation layer 8 can be disposed around the outer periphery of the induction coil 4, or the heat insulation layer 8 can also be disposed around the inner wall of the outer casing 1. In specific implementation, by covering the outer periphery of the induction coil 4 with the heat insulation layer 8, a better heat insulation effect can be achieved.

[0102] Optionally, in this embodiment, the heat insulation layer 8 is made of any one of aerogel, asbestos, ceramic and quartz materials.

[0103] It should be noted that the low-temperature non-combustion cigarette A and other contents of the heating non-combustion device 10 disclosed in the utility model can be seen from the prior art, and details are not repeated here.

[0104] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by the utility model specification and the attached drawings, or direct / indirect application in other related technical fields under the inventive concept of the utility model is included in the patent protection range of the utility model.
