[0051] With the increasing awareness of health, people realize that traditional cigarettes are harmful to health, and aerosol generating devices emerge as the times require. The aerosol generating device heats the aerosol substrate by heating means to release aerosol. The heating temperature is usually 200-400℃, which is lower than the combustion temperature of 600-900℃ of traditional cigarettes. Therefore, the harmful ingredients are greatly reduced, and aerosol generating devices have developed rapidly in recent years.

[0052] The aerosol generating device is used in cooperation with the heating means. When the heating means is used, there are usually peripheral heating and central heating. Central heating mainly includes resistance heating and electromagnetic induction heating. Resistance heating uses a needle or a sheet type heating needle installed in a resistance heating means. In use, the heating needle is inserted into the center of the aerosol substrate of the aerosol generating device, and the heating is controlled by the current. Electromagnetic induction heating uses an electromagnetic induction heating sheet placed in the center of the aerosol substrate. In use, the current of the induction coil in the electromagnetic induction heating means is controlled to generate electromagnetic induction to heat the electromagnetic induction heating sheet in the aerosol generating device.

[0053] The current aerosol generating device is either adapted to resistance heating means or adapted to electromagnetic induction heating means. The two types of heating means cannot be used together, causing inconvenience in use.

[0054] Referring to Figure 1 , Figure 1An aerosol generating device in an embodiment of the present application is shown, which comprises a filter section 1, a hollow section 2, an aerosol substrate section 3 and a guide section 4 connected in sequence, and a guide channel 41 is arranged in the guide section 4, which can allow a resistance heating device or an electromagnetic induction heating device to pass through and contact the aerosol substrate section 3.

[0055] The aerosol generating device described above adds a guide section downstream of the aerosol substrate section, and a guide channel is arranged in the guide section, which can allow a resistance heating device or an electromagnetic induction heating device to pass through and contact the aerosol substrate section, so that the aerosol generating device can adapt to both resistance heating appliances and electromagnetic induction heating appliances, solving the problem of inconvenience caused by the incompatibility of the two types of heating appliances in traditional aerosol generating devices.

[0056] The aerosol generating device described above changes the airflow path and airflow speed entering the aerosol substrate section through the guide section and the guide channel in the guide section, improving the sensory quality of the aerosol generating device and achieving unexpected results.

[0057] The aerosol generating device described above allows the electromagnetic induction heating device to be reused, saving costs and reducing environmental pollution.

[0058] Understandably, when using resistance heating, the heating needle or heating sheet of the resistance heating appliance passes through the guide channel of the guide section and is inserted into the aerosol substrate section of the aerosol generating device; when using electromagnetic induction heating, the reusable electromagnetic heating sheet is first passed through the guide channel of the guide section, and then inserted into the aerosol substrate section of the aerosol generating device.

So that the electromagnetic induction sheet 5 can be clamped into the two guide grooves 42, not only facilitating the insertion of the electromagnetic induction sheet 5 into the aerosol substrate section 3, but also limiting the electromagnetic induction sheet 5 by the two guide grooves 42.

[0118] In some embodiments, the electromagnetic induction heating device further includes a base 6, the base 6 is equipped with a ventilation hole 61 and an electromagnetic induction sheet socket 62, one end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet socket 62, and the other end is used for inserting into the aerosol substrate section 3.

[0120] Figure 11 Further, the outer diameter of the base 6 is equal to the outer diameter of the guide section 4. The base is suitable for the guide section 4 of the non-heating device mounting groove 43, which is simple in structure, low in manufacturing cost, convenient to plug and pull, and will appropriately increase the length of the aerosol generating device.

[0121] Further, the outer diameter of the base 6 is equal to the outer diameter of the guide section 4. The base is suitable for the guide section 4 of the non-heating device mounting groove 43, which is simple in structure, low in manufacturing cost, convenient to plug and pull, and will appropriately increase the length of the aerosol generating device. ​

[0122] It should be noted that, Figure 11 a in FIG. 6 is a schematic diagram of the base structure of the guide section adapted to the non-heating appliance installation slot; Figure 11 b in FIG. 6 is a top view of the base structure of the guide section adapted to the non-heating appliance installation slot; Figure 11 c in FIG. 6 is a bottom view of the base structure of the guide section adapted to the non-heating appliance installation slot; Figure 11 d in FIG. 6 is a schematic diagram of the A-A cross-sectional structure of b; Figure 11 e in FIG. 6 is a schematic diagram of the B-B cross-sectional structure of b.

[0123] In some embodiments, please refer to Figure 12 The electromagnetic induction sheet socket 62 of the base 6 protrudes from the top surface of the base 6, which not only serves to fix the electromagnetic induction sheet, but also facilitates cooperation with the guide slot of the guide section.

[0124] It should be noted that, Figure 12 a in FIG. 7 is a schematic diagram of the top view structure of the base of the guide section adapted to the non-heating appliance installation slot with a guide slot; Figure 12 b in FIG. 7 is a schematic diagram of the bottom view structure of the base of the guide section adapted to the non-heating appliance installation slot with a guide slot; Figure 11 c in FIG. 7 is a schematic diagram of the A-A cross-sectional structure of a; Figure 11 d in FIG. 7 is a schematic diagram of the B-B cross-sectional structure of a. Wherein, Figure 12 a in FIG. 8 shows the cooperation state of the base with the electromagnetic induction sheet after being installed on the guide section of the non-heating appliance installation slot with a guide slot, and after the electromagnetic induction sheet is inserted into the guide section, the total length of the aerosol generating device is increased to a certain extent. Figure 13

[0125] In some embodiments, the base 6 is embedded in the heating appliance installation slot 43, and the base 6 is provided with a ventilation hole 61, and the ratio of the ventilation area of the ventilation hole 61 to the maximum ventilation area of the guide channel 41 is 1 / 3~2 / 3. The size of the base cooperates with the size of the heating appliance installation slot 43 of the guide section, so that the electromagnetic induction sheet with the base does not increase the length of the aerosol generating device after being inserted into the guide section; when the ratio of the ventilation area of the ventilation hole 61 to the maximum ventilation area of the guide channel 41 is 1 / 3~2 / 3, unexpected effects are obtained in improving the sensory quality of the aerosol generating device.

[0126] For example, the ratio of the ventilation area of the ventilation hole 61 to the maximum ventilation area of the guide channel 41 can be 1 / 3, 1 / 2 and 2 / 3, or within the range formed by any two of the above point values.

[0127] In some embodiments, the electromagnetic induction heating device includes an electromagnetic induction sheet 5 and a base 6, and the structure of the base 6 is as shown in Figure 10 ​As shown in a of the base 6, the base 6 is provided with an electromagnetic induction sheet socket 62, one end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet socket 62, and the other end is inserted into the aerosol substrate segment 3. The length of the bottom of the base 6 matches the length of the heating appliance installation slot 43, so that the base 6 can be embedded in the heating appliance installation slot 43. Correspondingly, the heating appliance installation slot 43 is two cuboid-shaped grooves arranged symmetrically.

[0128] In some embodiments, the electromagnetic induction heating device includes an electromagnetic induction sheet 5 and a base 6. The base 6 is provided with a ventilation hole 61 and an electromagnetic induction sheet socket 62. One end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet socket 62, and the other end is used to insert into the aerosol substrate segment 3. The outer diameter of the base 6 is smaller than the outer diameter of the guide segment 4, and the base 6 is embedded in the heating appliance installation slot 43. The electromagnetic induction sheet with such a base not only facilitates the use of the electromagnetic induction heating smoking set, but also improves the heating efficiency of the aerosol device.

[0129] As an example, the base can be a size-reduced Figure 11 As shown in the circular truncated cone-shaped base, the outer diameter of the base is smaller than the inner diameter of the heating appliance installation slot 43. The heating appliance installation slot 43 can be a circular groove matched with the circular truncated cone-shaped base. The heating appliance installation slot 43 accommodates the base without increasing the length of the aerosol generating device. The outer dimensions of the base match the dimensions of the heating appliance installation slot of the guide segment, so that after the electromagnetic induction sheet with the base is inserted into the guide segment, the length of the aerosol generating device is not increased. One end of the electromagnetic induction sheet matches the electromagnetic induction sheet socket 62 of the base, and the remaining dimensions match the guide channel or guide groove. Such an electromagnetic induction sheet with a base facilitates the use of the electromagnetic induction heating smoking set and improves the heating efficiency.

[0130] As an example, the base can be a size-reduced Figure 12 As shown in the base, the outer diameter of the base is smaller than the inner diameter of the heating appliance installation slot 43. The heating appliance installation slot 43 can be a circular groove matched with the base. The heating appliance installation slot 43 accommodates the base without increasing the length of the aerosol generating device. As shown in a of the base 6, the base 6 is provided with an electromagnetic induction sheet socket 62, one end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet socket 62, and the other end is inserted into the aerosol substrate segment 3. The length of the bottom of the base 6 matches the length of the heating appliance installation slot 43, so that the base 6 can be embedded in the heating appliance installation slot 43. Correspondingly, the heating appliance installation slot 43 is two cuboid-shaped grooves arranged symmetrically. Figure 13 As shown in b of the base 6, after the electromagnetic induction sheet 5 is inserted into the guide segment 4, the base 6 is embedded into the heating appliance installation slot of the guide segment 4, without changing the overall length of the aerosol device.

[0131] Further, the ratio of the gas passing area of the ventilation hole 61 to the maximum gas passing area of the guide channel 41 is 1 / 3~2 / 3. The aerosol generating device in the aerosol generating system is well adapted to the electromagnetic induction heating appliance, has high heating efficiency, and significantly improves the sensory quality of the aerosol generating device.

[0132] For example, the ratio of the air passage area of the vent hole 61 to the maximum air passage area of the guide passage 41 can be 1 / 3, 1 / 2 and 2 / 3, or a range formed by any two of the above.

[0133] In some embodiments, the thickness of the electromagnetic induction sheet 5 is < 2.0 mm.

[0134] In some embodiments, the electromagnetic induction sheet 5 is made of a material containing iron, cobalt or nickel.

[0135] In some embodiments, the base is made of a material that has no electromagnetic induction performance and a low thermal conductivity.

[0136] Further, the base is made of a ceramic material.
