[0051] With the increase of health awareness, people realize that traditional cigarettes are harmful to health, and aerosol generating devices have come into being. Aerosol generating devices heat the aerosol matrix through heating devices to release aerosol. The heating temperature is usually between 200℃ and 400℃, which is lower than the combustion temperature of traditional cigarettes of 600℃ to 900℃. No complex chemical reaction occurs, so the harmful components are greatly reduced. It has developed rapidly in recent years.

[0052] The aerosol generating device is used in conjunction with a heating device for heating. When heating with a heating device, there are usually two methods: peripheral heating and center heating. Center heating mainly includes resistance heating and electromagnetic induction heating. Resistance heating uses a needle-type or sheet-type heating needle installed in a resistance heating device. When in use, the heating needle is inserted into the center of the aerosol matrix of the aerosol generating device, and heating is performed by controlling the current; while electromagnetic induction heating uses an electromagnetic induction heating sheet placed in the center of the aerosol matrix. When in use, the current of the induction coil in the electromagnetic induction heating device is controlled, and the electromagnetic induction heating sheet in the aerosol generating device is heated by generating electromagnetic induction.

[0053] The current aerosol generating devices are either adapted to resistive heating devices or electromagnetic induction heating devices. The two heating devices cannot be used interchangeably, which causes inconvenience in use.

[0054] Refer to Figure 1, which shows an aerosol generating device in an embodiment of the present application, including a filter section 1, a hollow section 2, an aerosol matrix section 3 and a guide section 4 connected in sequence, and a guide channel 41 is provided in the guide section 4. The guide channel 41 can allow a resistive heating device or an electromagnetic induction heating device to pass through and contact the aerosol matrix section 3.

[0055] The above-mentioned aerosol generating device adds a guide section downstream of the aerosol matrix section and sets a guide channel in the guide section. The guide channel can allow a resistive heating device or an electromagnetic induction heating device to pass through and contact the aerosol matrix section, so that the aerosol generating device can be adapted to both resistive heating devices and electromagnetic induction heating devices, thereby solving the inconvenience problem caused by the inability of the two heating devices in traditional aerosol generating devices to be used interchangeably.

[0056] The aerosol generating device changes the airflow path and airflow velocity entering the aerosol matrix section through the guiding section and the guiding channel in the guiding section, thereby improving the sensory quality of the aerosol generating device and achieving unexpected results.

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

[0058] It can be understood that when the resistance heating method is adopted, the heating needle or heating plate of the resistance heating device passes through the guide channel of the guide section and is inserted into the aerosol matrix section of the aerosol generating device; when the electromagnetic induction heating method is adopted, the reusable electromagnetic heating plate is first passed through the guide channel of the guide section and then inserted into the aerosol matrix section of the aerosol generating device.

[0059] In some embodiments, the aerosol generating device comprises a filter section, a hollow section, an aerosol matrix section and a guide section connected in sequence, and one or more layers of wrapping paper for wrapping and forming, wherein a guide channel is provided in the guide section, and the guide channel can allow a resistance heating device or an electromagnetic induction heating device to pass through and contact the aerosol matrix section. The wrapping paper wraps the filter section, the hollow section, the aerosol matrix section and the guide section.

[0060] In some embodiments, please refer to Figures 1 and 2, the guide channel 41 runs through the guide section 4, one end of the guide channel 41 extends to the aerosol matrix section 3, and the other end extends to the surface of the guide section 4 away from the aerosol matrix section 3. The aerosol generating device with this structure has good adaptability to both the resistive heating device and the electromagnetic induction heating device, and the two heating methods can be switched freely, which greatly improves the versatility and convenience of the aerosol generating device, and the sensory quality of the aerosol generating device is also improved.

[0061] In some embodiments, please refer to Figures 1 and Figure 3The guide channel 41 is in a circular hole shape, and the inner diameter of the guide channel 41 is equal from one end close to the aerosol matrix segment 3 to the other end far away from the aerosol matrix segment 3.

[0062] It can be understood that when the guide channel is in the shape of a circular hole, the inner diameter of the guide channel refers to the diameter of the cross section of the guide channel. In this case, the inner diameters of the guide channel are equal at all locations.

The aerosol generating device of this structure further optimizes the airflow path and speed of the aerosol matrix segment, improves the sensory quality of the heated cigarette, and makes the draw resistance small, the draw consistency good, and the aerosol richer and fuller.

[0065] It can be understood that when the guide channel is in the shape of a trumpet hole, the inner diameter of the guide channel refers to the diameter of the cross section of the guide channel.

[0082] In some embodiments, a guide groove 42 is provided on the side wall of the guide channel 41 , and the guide groove 42 extends along the axial direction of the guide channel 41 . The guide groove 42 is used to guide the electromagnetic induction heating device to pass through the guide channel 41 and contact the aerosol matrix segment 3 .

[0083] In some of the embodiments, one or more guide grooves 42 are further provided on the guide section 4 .

[0084] In some of the embodiments, at least two guide grooves 42 are further provided on the guide section 4. The guide grooves 42 are symmetrically arranged on the inner wall of the guide channel 41 for guiding the electromagnetic induction heating device to be inserted into the aerosol matrix section 3 and to limit the electromagnetic induction heating component.

[0085] It is understandable that two, four or six guide grooves 42 can be provided according to different sizes, wherein every two guide grooves 42 are symmetrical about the central axis of the guide section 4 and the sizes of the two symmetrical guide grooves 42 are consistent, so as to adapt to electromagnetic induction heating plates of different thicknesses.

The heating device installation groove 43 is provided at one end of the guide channel 41 away from the aerosol matrix section 3 and is connected to the guide groove 42. The heating device installation groove 43 is used to embed the base of the electromagnetic induction sheet. When the electromagnetic induction sheet with the base is used in conjunction, the length of the original aerosol generating device can still be maintained after the magnetic induction sheet is inserted into the aerosol matrix section 3, so that the electromagnetic heating effect is better.

This allows the electromagnetic induction sheet 5 to be inserted into the two guide grooves 42, which not only facilitates the insertion of the electromagnetic induction sheet 5 into the aerosol matrix segment 3, but also allows the guide grooves 42 to limit the electromagnetic induction sheet 5.

[0113] In some embodiments, the electromagnetic induction sheet is a rectangular sheet structure, and the length of the electromagnetic induction sheet 5 is less than or equal to the total length of the aerosol matrix segment 3 and the guide segment 4, so that the electromagnetic induction sheet 5 can be fully inserted into the aerosol matrix segment 3.

[0114] In some embodiments, the electromagnetic induction sheet 5 is in the shape of a rectangular sheet, the length of the electromagnetic induction sheet 5 is less than or equal to the total length of the aerosol matrix segment 3 and the guide segment 4, and the width of the electromagnetic induction sheet 5 is less than or equal to the minimum inner diameter of the guide channel 41. This allows the electromagnetic induction sheet to be smoothly inserted into the aerosol matrix segment 3.

[0115] In some of these implementations, see Fig.10 A base 6 for fixing the electromagnetic induction sheet 5 is provided at the bottom of the electromagnetic induction sheet 5 . Fig.10 a is a schematic diagram of the structure of the first electromagnetic induction sheet and its base; Fig.10 b is a schematic diagram of the structure of the second electromagnetic induction sheet and its base; Fig.10 Figure c is a schematic diagram of the structure of the third electromagnetic induction sheet and its base.

[0116] like Fig.10 As shown in a in FIG. 1 , the electromagnetic induction sheet 5 may be in the shape of a rectangular sheet; Fig.10 As shown in b in the figure, the electromagnetic induction sheet 5 can be in the shape of a rectangular thin sheet, and a plug connector is provided at the bottom end; as shown in c in the figure, the electromagnetic induction sheet 5 can be in the shape of a thick plate, and a plug connector is provided at the bottom end.

[0117] In some of these implementations, see Fig.10 In the electromagnetic induction sheet 5 of a, the electromagnetic induction heating device only includes the electromagnetic induction sheet 5 shown in the upper part, and does not include the base 6 shown in the lower part. The electromagnetic induction sheet without a base has a simple structure and low manufacturing cost.

[0118] In some embodiments, the electromagnetic induction sheet 5 is in the shape of a rectangular sheet, and the length of the electromagnetic induction sheet 5 is less than or equal to the total length of the aerosol matrix segment 3 and the guide segment 4; the width of the electromagnetic induction sheet 5 is greater than the minimum inner diameter of the guide channel 41, and the width of the electromagnetic induction sheet 5 is less than the minimum spacing between the two symmetrically arranged guide grooves 42. In order to facilitate the electromagnetic induction sheet 5 to be inserted into the two guide grooves 42, it is not only convenient for the electromagnetic induction sheet 5 to be inserted into the aerosol matrix segment 3, but the two guide grooves 42 can also limit the electromagnetic induction sheet 5.

[0119] In some embodiments, the electromagnetic induction heating device further comprises a base 6 , which is provided with a vent 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 be inserted into the aerosol matrix segment 3 .

[0120] In some of these implementations, see Fig.11 The base 6 is in a truncated cone shape and is provided with a vent hole 61 and an electromagnetic induction sheet insert 62 . One end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet insert 62 , and the other end is used to be inserted into the aerosol matrix segment 3 .

[0121] Furthermore, the outer diameter of the base 6 is equal to the outer diameter of the guide section 4. The base is adapted to the guide section 4 without the heating device installation groove 43, has a simple structure, low manufacturing cost, and is easy to plug and unplug, and will appropriately increase the length of the aerosol generating device.

[0122] It should be noted that Fig.11 a is a schematic diagram of the three-dimensional structure of the base adapted to the guide section of the installation groove of the non-heating appliance; Fig.11 b is a top view of the base adapted to the guide section of the installation groove of the non-heating appliance; Fig.11 c is a bottom view of the base adapted to the guide section of the installation groove of the non-heating appliance; Fig.11 d in the figure is a schematic diagram of the AA cross-section structure of b; Fig.11 In figure e, it is a schematic diagram of the BB cross-section structure of b.

[0123] In some of these implementations, see Fig.12 The electromagnetic induction sheet insert 62 of the base 6 protrudes from the top surface of the base 6. The electromagnetic induction sheet insert 62 not only fixes the electromagnetic induction sheet, but also facilitates the cooperation with the guide groove of the guide section.

[0124] It should be noted that Fig.12 a in the figure is a schematic diagram of the top view of the base structure of the guide section adapted to the installation groove of the heating device without the guide groove; Fig.12 b is a schematic diagram of the bottom structure of the base adapted to the guide section having a guide groove without a heating device installation groove; Fig.11 c is a schematic diagram of the AA cross-sectional structure of a; Fig.11 d in the figure is a schematic diagram of the BB cross-sectional structure of a. Fig.12 The matching state of the base a after the electromagnetic induction sheet is installed with the guide section without the heating device installation groove but with the guide groove is as follows Fig.13 As shown in a in FIG. 1 , after the electromagnetic induction sheet is inserted into the guide section, the total length of the aerosol device will be increased to a certain extent.

[0125] In some embodiments, the base 6 is embedded in the heating device installation groove 43, and a vent hole 61 is provided on the base 6. The ratio of the air passing area of ​​the vent hole 61 to the maximum air passing area of ​​the guide channel 41 is 1 / 3 to 2 / 3. The outer dimensions of the base match the dimensions of the heating device installation groove 43 of the guide section, so that after the electromagnetic induction sheet with the base is inserted into the guide section, the length of the aerosol generating device is not increased; when the ratio of the air passing area of ​​the vent hole 61 to the maximum air passing area of ​​the guide channel 41 is 1 / 3 to 2 / 3, an unexpected effect is obtained in improving the sensory quality of the aerosol generating device.

[0126] As an example, the ratio of the air flow area of ​​the vent hole 61 to the maximum air flow area of ​​the guide channel 41 may be 1 / 3, 1 / 2, or 2 / 3, or within a 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. The structure of the base 6 is as follows: Fig.10As shown in a in FIG. 1 , the base 6 is provided with an electromagnetic induction sheet insert 62, one end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet insert 62, and the other end is inserted into the aerosol matrix segment 3, and the bottom length of the base 6 matches the length of the heating device installation groove 43, so that the base 6 can be embedded in the heating device installation groove 43. Accordingly, the heating device installation groove 43 is two symmetrically arranged rectangular parallelepiped grooves.

[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 vent hole 61 and an electromagnetic induction sheet insert 62, one end of the electromagnetic induction sheet 5 is fixed in the electromagnetic induction sheet insert 62, and the other end is used to insert into the aerosol matrix 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 device installation groove 43. The electromagnetic induction sheet with such a base is not only convenient for use with electromagnetic induction heating smoking devices, but also improves the heating efficiency of the aerosol device.

[0129] As an example, the base may be a reduced size Fig.11 The truncated cone-shaped base shown in the figure has an outer diameter smaller than the inner diameter of the heating device installation groove 43. The heating device installation groove 43 can be a circular groove matched with the truncated cone-shaped base. The heating device installation groove 43 accommodates the base so as not to increase the length of the aerosol generating device. The outer dimensions of the base match the dimensions of the heating device installation groove of the guide section, so that after the electromagnetic induction sheet with the base is inserted into the guide section, 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; this electromagnetic induction sheet with a base is convenient for use with electromagnetic induction heating smoking utensils, and improves the heating efficiency.

[0130] As an example, the base may be a reduced size Fig.12 The base shown in the figure has an outer diameter smaller than the inner diameter of the heating device installation groove 43. The heating device installation groove 43 can be a circular groove matched with the base. The heating device installation groove 43 accommodates the base so as not to increase the length of the aerosol generating device. The base 6 is equipped with the electromagnetic induction sheet 5, and the matching state with the guide section 4 having the heating device installation groove and the guide groove is as shown in FIG. Fig.13 As shown in b, after the electromagnetic induction sheet 5 is inserted into the guide section 4, the base 6 is embedded in the heating device installation groove of the guide section 4, without changing the overall length of the aerosol device.

[0131] Furthermore, the ratio of the air flow area of ​​the vent hole 61 to the maximum air flow area of ​​the guide channel 41 is 1 / 3 to 2 / 3. The aerosol generating device in the aerosol generating system has good compatibility with the electromagnetic induction heating device and high heating efficiency, which significantly improves the sensory quality of the aerosol generating device.

[0132] As an example, the ratio of the air flow area of ​​the vent hole 61 to the maximum air flow area of ​​the guide channel 41 may be 1 / 3, 1 / 2, or 2 / 3, or within a range formed by any two of the above point values.

[0133] In some embodiments, the thickness of the electromagnetic induction sheet 5 is less than 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 of the embodiments, the base is made of a material having no electromagnetic induction performance and low thermal conductivity.

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

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
