TECHNICAL FIELD

Embodiments of the present application relate to the field of heat-not-burn aerosol generation technologies, and in particular, to an aerosol generation device, a heater for an aerosol generation device, and a control method.

BACKGROUND

For tobacco products (such as cigarettes and cigars), tobacco is burnt during use to produce tobacco smoke. Attempts are made to replace these tobacco-burning products by making products that release compounds without burning.

An example of such products is a heating device, which releases compounds by heating rather than burning materials. For example, the material may be tobacco or other non-tobacco products. These non-tobacco products may or may not include nicotine. A known heating device includes a plurality of tubular heaters which are spaced apart in a longitudinal manner and surround tobacco or different sections of other non-tobacco products, and then the plurality of tubular heaters that are spaced apart are independent started to respectively heat tobacco or different sections of other non-tobacco products.

An embodiment of the present application provides an aerosol generation device 100 that heats but not burns an aerosol generation product 1000, for example, a cigarette, to volatilize or release at least one component of the aerosol generation product 1000 to form an aerosol for inhalation, for example as shown in FIG. 1.

Further, in an optional implementation, a tobacco-contained material that releases volatile compounds from base bodys when being heated is preferably used as the aerosol generation product 1000. Alternatively, a non-tobacco material that can be suitable for electrical heating smoke generation after being heated may be used. A solid substrate is preferably used as the aerosol generation product 1000, which may include powder, particles, shreds, strips, or flakes of one or more of a vanilla leaf, a tobacco leaf, homogenized tobacco, or expanded tobacco. Alternatively, a solid substrate may include additional tobacco or non-tobacco volatile flavor compounds, so as to be released when the base body is heated.

In addition, as shown in FIG. 1, after the aerosol generation product 1000 is received in an aerosol generation device 100, it is advantageous that a portion of the aerosol generation product is exposed outside the aerosol generation device 100, such as a filter tip, for inhalation by a user.

A configuration of an aerosol generation device according to an embodiment of the present application may be shown in FIG. 1. The overall shape of the device is roughly configured into a flat cylinder shape, and an external member of the aerosol generation device 100 includes:

• • a housing 10, having a hollow structure inside, to form an assembling space for a component with a necessary function, such as an electronic device and a heating device. The housing 10 has a near end 110 and a far end 120 which are opposite to each other in a lengthwise direction.

The near end 110 is provided with an opening 111. The aerosol generation product 1000 may be received in the housing 10 through the opening 111 to be heated or may be removed from the housing 10.

Further, as shown in FIG. 1, the aerosol generation device 100 further includes:

• • a heater 30, which at least partially surrounds and defines the chamber. When the aerosol generation product 1000 is received in the housing 10, the heater 30 at least partially surrounds or encloses the aerosol generation product 1000, and performs heating from an outer circumference of the aerosol generation product 1000. Moreover, when received in the housing 10, the aerosol generation product 1000 is at least partially accommodated and maintained in the heater 30.

  • and an infrared transmitting layer 32, an infrared transmitting layer 33, and an infrared transmitting layer 34 which are formed or arranged on the base body 31. In this embodiment, the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 are formed on an outer surface of the base body 31 by deposition, spraying, wrapping, or the like.

The infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 are sequentially spaced apart.

In some implementations, the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 may be coatings prepared from a ceramic material such as zirconium, an Fe—Mn—Cu material, a tungsten material, a transition metal, and their oxides.

In some implementations, the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 are composed of an oxide of at least one metal element such as Mg, Al, Ti, Zr, Mn, Fe, Co, Ni, Cu, Cr, and Zn. These metal oxides may transmit far-infrared ray with a heating effect when heated to an appropriate temperature. A thickness of the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 may be preferably 30 μm to 50 μm. A mode of formation on the surface of the tubular base body 31 may be achieved by spraying the oxides of the above metal elements onto the outer surface of the tubular base body 31 through atmospheric plasma spraying and then curing the outer surface.

In some embodiments, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 have substantially the same lengths. For example, in a specific embodiment, the lengths of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 are all 8 mm to 12 mm. For another example, in a specific embodiment, the lengths of the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 are 9.5 mm.

Alternatively, in still some embodiments, the length of any one of the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34 is different from the lengths of the other two infrared transmitting layers. Alternatively, in still some changed embodiments, each of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 has a length different from the lengths of the other two infrared transmitting layers.

Alternatively, in still some embodiments, extension lengths of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 gradually change in an axial direction of the heater 30. For example, in some specific embodiments, the extension lengths of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 gradually or sequentially increase. Alternatively, the extension lengths of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 gradually or sequentially decrease.

Alternatively, in still some embodiments, the length of the infrared transmitting layer 33 is less than the length of any one of the infrared transmitting layer 32 and the infrared transmitting layer 34. Alternatively, in still some embodiments, the length of the infrared transmitting layer 33 is greater than the length of any one of the infrared transmitting layer 32 and the infrared transmitting layer 34.

Alternatively, in still some embodiments, heater 30 may further include three infrared transmitting layers, namely, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34. Alternatively, in still some embodiments, the heater 30 further includes more infrared transmitting layers, for example, four, five, six, or more infrared transmitting layers sequentially spaced apart in an axial direction of the base body 31.

Further, FIG. 2 to FIG. 4 show a schematic structural diagram of a heater 30 according to an embodiment. In this embodiment, the heater 30 includes:

• • a first end 311 and a second end 312 which face away from each other in an axial direction; and
  • an infrared-transmittable base body 31, which is constructed into a tubular shape. In an implementation, two ends of the base body 31 in a lengthwise direction respectively define the first end 311 and the second end 312 of the heater 30. Furthermore, an inner chamber 310 of the base body 31 at least partially defines a chamber for receiving the aerosol generation product 1000.

In addition, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 are formed on the base body 31 and are sequentially arranged in an axial direction of the base body 31. Certainly, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 are spaced apart.

Further as shown in FIG. 2 to FIG. 4, the infrared transmitting layer 32 is arranged near the first end 311; the infrared transmitting layer 34 is arranged near the second end 312; and the infrared transmitting layer 33 is located between the infrared transmitting layer 32 and the infrared transmitting layer 34.

In addition, the following are further defined on a surface of the base body 31:

• • an exposed section 313, located between the first end 311 and the infrared transmitting layer 32;
  • an exposed section 314, located between infrared transmitting layer 32 and the infrared transmitting layer 33 and separating the infrared transmitting layer 32 from the infrared transmitting layer 33;
  • an exposed section 315, located between infrared transmitting layer 33 and the infrared transmitting layer 34 and separating the infrared transmitting layer 33 from the infrared transmitting layer 34; and
  • an exposed section 316, located between the infrared transmitting layer 34 and the second end 312.

Furthermore, in some embodiments, in the axial direction of the base body 31, the exposed section 313, the exposed section 314, and the exposed section 315 have substantially the same sizes. For example, in some specific embodiments, the exposed section 313, the exposed section 314, and the exposed section 315 have lengths of approximately 0.5 mm to 3 mm.

In addition, in some embodiments, the length of the exposed section 316 in the axial direction of the base body 31 is greater than the length of the exposed section 313 and/or the length of the exposed section 314 and/or the length of the exposed section 315. For example, in some specific embodiments, the length of the exposed section 316 in the axial direction of the base body 31 is between 3 mm and 5 mm.

In some embodiments, temperature measurement identification sections are arranged on the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34, to indicate adhesion of temperature sensors. For example, in FIG. 2 to FIG. 4, a temperature measurement identification section 321 is arranged on the infrared transmitting layer 32, and is a sprayed identifiable color, or a hollowed hole formed in the infrared transmitting layer 32, or an identifiable graph or pattern, or the like. During preparation, a temperature sensor is bonded to the temperature measurement identification section 321 in a mounted manner, a welded manner, or the like, to accurately sense a temperature of the infrared transmitting layer 32. Similarly, the infrared transmitting layer 33 and the infrared transmitting layer 34 further have temperature measurement identification sections.

In some embodiments, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 are all prepared from the same material, so that they have the same infrared radiation wavelength or infrared radiation efficiency during heating of different sections of the aerosol generation product 1000.

Alternatively, in still some changed embodiments, one of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 is prepared from a material that is different from materials of the other two infrared transmitting layers, and an infrared transmitting spectrum of one of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 and infrared transmitting spectra of the other two infrared transmitting layers have different WLPs (a peak wavelength which is a wavelength corresponding to a maximum radiation power) in its infrared transmitting spectrum from the other two, which can respectively adapt to optimal absorption wavelength ranges of different organic components in the aerosol generation product 1000. Alternatively, in still some embodiments, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 are all prepared using different materials, and any two of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 have different infrared transmission spectra and/or different WLPs.

The electrode coating 352 is basically opposite to the electrode coating 351 in the radial direction of the base body 31 or the heater 30. A length of the electrode coating 352 in the axial direction of the heater 30 only covers the infrared transmitting layer 32.

The portion 3542 is closer to the second end 312 than the portion 3541. In addition, the portion 3541 spans the infrared transmitting layer 33 and the infrared transmitting layer 34, and is partially conductively connected to the infrared transmitting layer 33 and partially conductively connected to the infrared transmitting layer 34. Alternatively, the electrode coating 354 extends from the infrared transmitting layer 33 to the infrared transmitting layer 34. Alternatively, an extension length of the electrode coating 354 spans or basically spans the infrared transmitting layer 33 and infrared transmitting layer 34. Alternatively, a length of the portion 3541 of the electrode coating 354 is basically equal to a sum of the lengths of the infrared transmitting layer 33, the exposed section 315, and the infrared transmitting layer 34. In addition, the portion 3542 of the electrode coating 354 is located in the exposed section 316, to connect the electrode coating 354 to the circuit board 140.

In addition, in some embodiments, the above electrode coating 351 and/or the electrode coating 352 and/or the electrode coating 353 and/or the electrode coating 354 uses a low-resistivity metal or alloy, such as silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or an alloy thereof. The above electrode coating 351 and/or the electrode coating 352 and/or the electrode coating 353 and/or the electrode coating 354 is formed by spraying, printing, or the like.

In addition, in some embodiments, the electrode coating 351 and/or the electrode coating 352 and/or the electrode coating 353 and/or the electrode coating 354 are basically in lengthwise shapes. In addition, the electrode coating 351 and/or the electrode coating 352 and/or the portion 3531 of the electrode coating 353 and/or the portion 3541 of the electrode coating 354 has a width of approximately 2 mm to 4 mm.

In addition, further as shown in FIG. 2 to FIG. 4, the heater 30 further includes:

• • a conductive element 361, which has a length or a shape that is basically the same as the length or the shape of the electrode coating 351. During assembling, the conductive element 361 is turned on by resisting against or abutting against the electrode coating 351. The conductive element 361 is connected to the circuit board 140 through a welded conductive wire 3611, so that the electrode coating 351 is connected to the circuit board 140.

In addition, further as shown in FIG. 2 to FIG. 4, the heater 30 further includes:

• • a conductive element 362, which has a length or a shape that is basically the same as the length or the shape of the electrode coating 352.

Afterwards, after the conductive element 363 and the conductive element 364 are connected to the circuit board 140 through wires, the electrode coating 353 and the electrode coating 354 are respectively connected to the circuit board 140. The applicant provides the shapes and structures of the conductive element 363 and the conductive element 364, assembling, fixing, and elasticities of the conductive element 363 and the conductive element 364, and other details in Chinese Patent Application No. CN215958354U, which is incorporated by reference in its entirety.

Alternatively, in some other embodiments, each of the electrode coating 351 and/or the electrode coating 352 and/or the electrode coating 353 and/or the electrode coating 354 is directly connected to the circuit board 140 through a welding wire.

Alternatively, in still some embodiments, an implementation for supplying power to the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 is performed only through the conductive element 361, the conductive element 362, the conductive element 363, and the conductive element 364.

Alternatively, in still some changed embodiments, the heater 30 further includes:

In addition, in some embodiments, a thermoplastic clinging member is further used for fastening or maintaining one or more of the conductive element 361, the conductive element 362, the conductive element 363, and the conductive element 364.

Alternatively, in still some changed embodiments, the heater 30 further includes:

• • a thermal insulation element, which is used for surrounding or enclosing the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34, to provide thermal insulation on the outer sides of the infrared transmitting layer 32 and/or the infrared transmitting layer 33 and/or the infrared transmitting layer 34. The thermal insulation element is, for example, a rolled-up aerogel blanket, a porous material, or a vacuum tube.

Alternatively, in some other changed embodiments, the thermal insulation element of the heater 30 is a tube having an inner thermal insulation cavity. A thermal insulation cavity is provided between an inner surface and an outer surface of the tubular thermal insulation element. A pressure of the thermal insulation cavity is less than an external pressure. Namely, the thermal insulation element is a vacuum thermal insulation tube having a vacuum degree. Alternatively, in still some changed embodiments, a thermal insulation cavity is provided between an inner surface and an outer surface of the tubular thermal insulation element, and the thermal insulation cavity is filled with thermal insulation gas, such as argon. At the same pressure and temperature, a heat conduction coefficient of argon is approximately one third less than that of air, thereby effectively providing thermal insulation.

In some embodiments, the circuit board 140 is selectively connected to two or more of the electrode coating 351/the conductive element 361, the electrode coating 352/the conductive element 362, the electrode coating 353/the conductive element 363, and the electrode coating 354/the conductive element 364, to selectively cause one or more of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 of the heater 30 to work. For example:

In a specific embodiment, when the electrode coating 351/the conductive element 361 is connected to a positive electrode of the battery cell 130, and the electrode coating 352/the conductive element 362 is connected to a negative electrode of the battery cell 130, a current in the circumferential direction can be formed on the infrared transmitting layer 32, so that the infrared transmitting layer 32 is caused to work, as shown in FIG. 5. In this case, the heater 30 transmits the infrared ray through the infrared transmitting layer 32 to heat a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 32.

Moreover, when the electrode coating 351/the conductive element 361 is connected to the positive electrode of the battery cell 130, and the electrode coating 354/the conductive element 364 is connected to the negative electrode of the battery cell 130, a current in the circumferential direction can be formed on the infrared transmitting layer 33, so that the infrared transmitting layer 33 is caused to work, as shown in FIG. 6. In this case, the heater 30 transmits the infrared ray through the infrared transmitting layer 33 to heat a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 33.

Moreover, when the electrode coating 353/the conductive element 363 is connected to the positive electrode of the battery cell 130, and the electrode coating 354/the conductive element 364 is connected to the negative electrode of the battery cell 130, a current in the circumferential direction can be formed on the infrared transmitting layer 34, so that the infrared transmitting layer 34 is caused to work, as shown in FIG. 7. In this case, the heater 30 transmits the infrared ray through the infrared transmitting layer 34 to heat a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 34.

Moreover, when the electrode coating 351/the conductive element 361 is connected to the positive electrode of the battery cell 130, and the electrode coating 353/the conductive element 363 is connected to the negative electrode of the battery cell 130, the conductive coating 354 is used as a conductive intermediate, i.e. an empty electrode, for serial connection between the infrared transmitting layer 33 and the infrared transmitting layer 34, and currents in the circumferential direction can be simultaneously formed on the infrared transmitting layer 33 and the infrared transmitting layer 34, so that the infrared transmitting layer 33 and the infrared transmitting layer 34 are caused to work simultaneously, as shown in FIG. 8. In this case, the infrared transmitting layer 32 does not work. In this case, in the heater 30, the infrared transmitting layer 33 and the infrared transmitting layer 34 simultaneously transmit infrared rays to simultaneously heat a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 33 and a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 34.

Moreover, when the electrode coating 352/the conductive element 362 is connected to the positive electrode of the battery cell 130, and at the same time, the electrode coating 354/the conductive element 364 is connected to the negative electrode of the battery cell 130, the electrode coating 351 serves as a serial connection intermediate between the infrared transmitting layer 32 and the infrared transmitting layer 33. Currents can be simultaneously formed on the infrared transmitting layer 32 and the infrared transmitting layer 33 in the circumferential direction, so that the infrared transmitting layer 32 and the infrared transmitting layer 33 are caused to work simultaneously, as shown in FIG. 9. In this case, the infrared transmitting layer 34 does not work. In this case, in the heater 30, the infrared transmitting layer 32 and the infrared transmitting layer 33 simultaneously transmit infrared rays to simultaneously heat a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 32 and a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 33.

Moreover, when the electrode coating 352/the conductive element 362 is connected to the positive electrode of the battery cell 130 and the electrode coating 353/the conductive element 363 is connected to the negative electrode of the battery cell 130, the electrode coating 351 serves as a serial connection intermediate between the infrared transmitting layer 32 and the infrared transmitting layer 33, and the electrode coating 354 serves as a serial connection intermediate between the infrared transmitting layer 33 and the infrared transmitting layer 34. In this case, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 can be caused to work simultaneously, as shown in FIG. 10. In this case, the heater 30 simultaneously heats a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 32, a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 33, and a section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 34. Namely, in this case, the aerosol generation product 1000 is entirely heated.

In addition, in some embodiments, for example, as shown in FIG. 11, in the heater 30, a wire/a conductive element 39 is used to connect the conductive coating 351/the conductive element 361 to the conductive coating 354/the conductive element 364, so that the conductive coating 351 and the conductive coating 354 form an integrally conductive short-circuit state. In this case, the electrode coating 352/the conductive element 362 is then connected to the positive electrode of the battery cell 130, and the electrode coating 353/the conductive element 363 is then connected to the negative electrode of the battery cell 130. Because of the short circuit between the conductive coating 351 and the conductive coating 354, current does not flow through the infrared transmitting layer 33, thereby forming a state in which the infrared transmitting layer 32 and the infrared transmitting layer 34 work and the infrared transmitting layer 33 does not work.

Alternatively, when the conductive coating 351 and the conductive coating 354 form the short-circuit state by using the wire or the conductive element 39, it can further selectively connect the conductive coating 351/the conductive element 361 to the positive electrode of the battery cell 130 and connect the conductive coating 352/the conductive element 362 to the negative electrode of the battery cell 130. In this case, a state in which the infrared transmitting layer 32 works only, and the infrared transmitting layer 33 and the infrared transmitting layer 34 do not work. Alternatively, in this case, it can further connect the electrode coating 353/the conductive element 363 to the positive electrode of the battery cell 130 and connect the electrode coating 354/the conductive element 364 to the negative electrode of the battery cell 130, so that only the infrared transmitting layer 34 works, and the infrared transmitting layer 32 and the infrared transmitting layer 33 do not work.

In the foregoing implementations, by selectively connecting the positive electrode and the negative electrode between different electrode coatings or conductive elements respectively to input a voltage, any one, two, or three of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 work in series.

In still another embodiment of the present application, an electrode connection control mode is further provided, in which the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 work simultaneously, but one of the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 has a higher power.

For example, in an embodiment shown in FIG. 12, the conductive coating 352/the conductive element 362 are connected to the conductive coating 353/the conductive element 363 through the wire or the conductive element 39, so that the conductive coatings/the conductive elements are directly turned on or in a short-circuit state. In this case, the conductive coating 351/the conductive element 361 is connected to the positive electrode of the battery cell 130, and the conductive coating 352 and/or the conductive coating 353 is connected to the negative electrode, to provide a voltage. In this case, in this state, a current i11 that directly flows from the conductive coating 351 to the conductive coating 352 through the infrared transmitting layer 32, and a current i12 that flows from the conductive coating 351 to the conductive coating 353 through the infrared transmitting layer 33 and the infrared transmitting layer 34 that are connected in series are generated. On a power supply path, the infrared transmitting layer 32 and the serially connected infrared transmitting layer 33 and infrared transmitting layer 34 form two circuit paths connected in parallel to each other.

In the implementation of FIG. 12, the infrared transmitting layer 32, the infrared transmitting layer 33, and the infrared transmitting layer 34 work simultaneously. However, a resistance of the infrared transmitting layer 32 is less than an equivalent resistance of the infrared transmitting layer 33 and the infrared transmitting layer 34 that are connected in series. For example, when the resistance of the infrared transmitting layer 32, the resistance of the infrared transmitting layer 33, and the resistance of the infrared transmitting layer 34 are the same and represented by R, the current i11 flowing through the infrared transmitting layer 32 is twice a current flowing through the infrared transmitting layer 33 and the infrared transmitting layer 34 that are connected in series. The power of the infrared transmitting layer 32 is P1=i11²×R. The power of the infrared transmitting layer 33 and/or the infrared transmitting layer 34 is P2=i12×R. Power P2 is ¼ of power P1. In this case, the section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 32 is heated faster or at a higher temperature than the section surrounded by the infrared transmitting layer 33 and/or the infrared transmitting layer 34. In the implementation of FIG. 12, the infrared transmitting layer 32 is in a relatively high power density state, and the infrared transmitting layer 33 and/or the infrared transmitting layer 34 is in a relatively low power density state.

Alternatively, for another example, in an embodiment shown in FIG. 13, the conductive coating 351/the conductive element 361 is connected to the positive electrode, and the conductive coating 354/the conductive element 364 is connected to the negative electrode, thus providing a voltage. In this case, a current i11a flowing from the conductive coating 351/the conductive element 361 through the infrared transmitting layer 33 to the conductive coating 354/the conductive element 364 is formed, and a current i12a flowing from the conductive coating 351/the conductive element 361 through the infrared transmitting layer 32 and the infrared transmitting layer 34 that are connected in series to the conductive coating 354/the conductive element 364 is formed, making the power of the infrared transmitting layer 33 four times of the power of the infrared transmitting layer 32 and/or the power of the infrared transmitting layer 34. In this case, the section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 33 is heated faster or at a higher temperature than the section surrounded by the infrared transmitting layer 32 and/or the infrared transmitting layer 34.

Alternatively, for another example, in an embodiment shown in FIG. 14, the conductive coating 353/the conductive element 363 is connected to the positive electrode, and the conductive coating 354/the conductive element 364 is connected to the negative electrode, thus providing a voltage. In this case, a current i11b flowing from the conductive coating 353/the conductive element 363 through the infrared transmitting layer 34 to the conductive coating 354/the conductive element 364 is formed, and a current i12b flowing from the conductive coating 353/the conductive element 363 through the infrared transmitting layer 32 and the infrared transmitting layer 33 that are connected in series to the conductive coating 354/the conductive element 364 is formed, making the power of the infrared transmitting layer 34 four times of the power of the infrared transmitting layer 32 and/or the power of the infrared transmitting layer 33. In this case, the section of the aerosol generation product 1000 surrounded by the infrared transmitting layer 34 is heated faster or at a higher temperature than the section surrounded by the infrared transmitting layer 32 and/or the infrared transmitting layer 33.

Further, FIG. 15 shows a schematic diagram of heating different sections of an aerosol generation product 1000 by a heater 30 according to an embodiment. In this embodiment shown in FIG. 15, the aerosol generation product 1000 includes a section 1100 surrounded and heated by an infrared transmitting layer 32, a section 1200 surrounded and heated by an infrared transmitting layer 33, and a section 1300 surrounded and heated by an infrared transmitting layer 34. In this embodiment, the section 1100, section 1200, and section 1300 of the aerosol generation product 1000 are respectively located in different heating sections of the heater 30. For example, the section 1100 is located in a heating section defined around the infrared transmitting layer 32; the section 1200 is located in a heating section defined around the infrared transmitting layer 33; and the section 1300 is located in a heating section defined around the infrared transmitting layer 34. During implementation, by selectively connecting the heater 30 to a battery cell 130, the heater 30 can operate in various situations: only any one or two of the section 1100, the section 1200, and the section 1300 of the aerosol generation product 1000 are heated, or the section 1100, the section 1200, and the section 1300 of the aerosol generation product 1000 are simultaneously heated.

In addition, in this embodiment, by selectively connecting the heater 30 to the battery cell 130 in a different manner different, when the section 1100, the section 1200, and the section 1300 of the aerosol generation product 1000 are simultaneously heated, any one or two of the section 1100, the section 1200, and the section 1300 may be heated faster or at a higher temperature.

Alternatively, in a specific embodiment, for example, FIG. 16 shows a schematic diagram of a temperature curve of controlling a heater 30 to heat a section 1100, a section 1200, and a section 1300 of an aerosol generation product 1000 according to an embodiment. Where a curve S1 is a temperature curve indicating that the section 1100 is heated by an infrared transmitting layer 32; a curve S2 is a temperature curve indicating that the section 1200 is heated by an infrared transmitting layer 33; and a curve S3 is a temperature curve indicating that the section 1300 is heated by an infrared transmitting layer 34. A heating process includes:

Within a first time period (0 to t1), the battery cell 130 supplies power to the heater 30 in the manner shown in FIG. 12, so that the section 1100 is heated faster than the section 1200 and/or the section 1300. Moreover, within the first time period, the section 1100 is heated to a first target temperature which is, for example, temperature T1, and a heating temperature or a current temperature of the section 1200 and/or a heating temperature or a current temperature of the section 1300 is less than the first target temperature.

With a second time period (t1 to t2), the battery cell 130 supplies power to the heater 30 in the manner shown in FIG. 13, so that the section 1200 is heated faster than the section 1100 and/or the section 1300. Within the second time period, the section 1200 is heated to a second target temperature, which is, for example, temperature T2, and a heating temperature or a current temperature of the section 1300 is less than the second target temperature.

Within a third time period (t2 to t3), the battery cell 130 supplies power to the heater 30 in the manner shown in FIG. 14, so that the section 1300 is heated faster than the section 1100 and/or the section 1200. Within the third time period, the section 1300 is heated to a third target temperature, which is, for example, temperature T3. In addition, within the third time period, the section 1100, the section 1200, and the section 1300 can be heat to an extent that their temperatures are basically close or tend to be close.

Within a fourth time period (t3 to t4 or at the end), the battery cell 130 supplies power to the heater 30 in the manner shown in FIG. 10, so that when the section 1100, the section 1200, and the section 1300 are heated basically according to the close powers or temperatures till t4 or until vaping ends.

In some embodiments, the first target temperature T1, the second target temperature T2, and the third target temperature T3 may be the same. For example, temperature T1, temperature T2, and temperature T3 may all be set to be approximately 200° C. to 300° C. Alternatively, in still some embodiments, the first target temperature, the second target temperature, and the third target temperature are different. For example, in some embodiments, the first target temperature, the second target temperature, and the third target temperature sequentially or gradually increase or gradually decrease. For example, in an embodiment, the first target temperature T1, the second target temperature T2, and the third target temperature T3 may gradually increase. For example, in a specific embodiment, the first target temperature T1 may be set to 220° C. to 250° C.; the second target temperature T2 may be set to 240° C. to 270° C.; and the third target temperature T3 may be set to 260° C. to 350° C. In addition, in the foregoing embodiment, within the fourth time period, the temperatures of the section 1100, the section 1200, and the section 1300 are basically maintained to be the third target temperature.

In some embodiments, a length of the first time period is approximately 10 s to 150 s. A length of the second time period is approximately 20 s to 40 s. A length of the third time period is approximately 40 s to 120 s. A length of the fourth time period is approximately 60 s to 150 s. In a specific embodiment, the length of the first time period is approximately 130 s. The length of the second time period is approximately 25 s. The length of the third time period is approximately 100 s. The length of the fourth time period is approximately 120 s.

In some embodiments, the length of the fourth time period is greater than the length of the first time period and/or the length of the second time period and/or the length of the third time period. In some embodiments, the length of the first time period is greater than the length of the second time period and/or the length of the third time period.

For example, only the heating processes of the first time period, the second time period, and the third time period are included, and the process of the fourth time period is not included. Alternatively, only the heating processes of the first time period and the fourth time period are included, and the heating processes of the second time period and the third time period are not included.
