[0064] References to "embodiments" herein mean that the features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0065] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0066] One embodiment of the present application provides an aerosol generating device, which is a device that is coupled to or interacts with an aerosol generating article 2 to form an inhalable aerosol.

[0067] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming substrate that, when heated, releases volatile compounds that can form an aerosol. In one embodiment, the aerosol-generating article is removably connectable to an aerosol-generating device. The article may be disposable or reusable.

[0068] The aerosol-forming substrate may comprise a solid aerosol-forming substrate. The solid aerosol-forming substrate may comprise a tobacco-containing material containing volatile tobacco flavor compounds that are released from the aerosol-forming substrate upon heating. The solid aerosol-forming substrate may comprise a non-tobacco material. The solid aerosol-forming substrate may comprise a tobacco-containing material and a non-tobacco material.

[0069] Aerosol formation matrix can comprise liquid aerosol formation matrix.Liquid aerosol formation matrix can comprise the liquid of the tobacco-containing material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.Liquid aerosol formation matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., spices can comprise betel nut extract, menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide various fragrance or local flavor to the user.Vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.

[0070] The aerosol generating device has a containing cavity inside, and at least a part of the aerosol generating product 2 can be combined in the containing cavity. The aerosol generating device can be an electrically operated device, and the electrical component 1 adapted for the aerosol generating device can convert electrical energy into other energy that is beneficial for the aerosol generating product 2 to generate aerosol.

[0071] In one embodiment, the energy is thermal energy. When electrically conductive, the electrical element 1 generates and releases heat. At least a portion of this heat can heat the aerosol-generating article 2, causing the aerosol-generating article 2 to generate an aerosol. In one embodiment, the energy is infrared light energy. When electrically conductive, the electrical element 1 generates infrared radiation. At least a portion of this infrared radiation is directed toward the aerosol-generating article 2 and absorbed by the aerosol-generating article 2, thereby increasing the temperature of the aerosol-generating article 2 and generating an aerosol. In one embodiment, the energy is microwave energy. When electrically conductive, the electrical element 1 generates microwaves. These microwaves can cause the solvent or compound molecules in the aerosol-generating article 2 to vibrate at a high frequency, thereby increasing the temperature of the aerosol-generating article 2 and generating an aerosol. In one embodiment, the energy is magnetic energy. The aerosol-generating device or the aerosol-generating article 2 can include a susceptor. The susceptor can generate eddy currents and / or hysteresis under the influence of the magnetic energy, thereby generating heat to heat the aerosol-generating article 2 and generating an aerosol. It should be noted that the energy may also be other energy, such as ultrasound.

[0072] The electrical component 1 includes a first part 11 and a second part 12, which can generate the above-mentioned energy when electrically conductive. The first part 11 and the second part 12 can be connected to each other. Alternatively, the first part 11 can be integrally formed with the second part 12, that is, the electrical component 1 can be a continuous whole. When the electrical component 1 is a continuous whole, the first part 11 and the second part 12 can be two different parts on the electrical component 1, that is, there can be no obvious splicing or combination marks between the first part 11 and the second part 12. The first part 11 and the second part 12 can be made of the same material.

[0073] Since the first part 11 and the second part 12 are interconnected or integrally formed, energy can be transferred between the two when either of the first part 11 and the second part 12 is electrically conductive. Compared with transferring energy to other places and thus losing it, transferring energy between the first part 11 and the second part 12 can improve energy utilization and help reduce energy consumption.

[0074] In the embodiments shown in Figures 3 and 5 , the electrical component 1 is constructed in a mesh shape. The first portion 11 and the second portion 12 can be integrally formed from the same material, resulting in faster energy transfer, lower energy transfer loss, and lower energy transfer barriers. It should be noted that the entire electrical component 1 can be constructed as a spiral coil, with the first portion 11 and the second portion 12 forming part of the spiral coil. The first portion 11 and the second portion 12 can be two coils formed from the same wire.

[0075] The aerosol-generating device further includes a power supply assembly 3 and a delay circuit 4. The delay circuit 4 can be connected to the electrical component 1. The power supply assembly 3 is used to provide power / electrical energy for the first portion 11 and the second portion 12 to generate energy. Only one of the first portion 11 and the second portion 12 can be associated with the delay circuit 4, while the other portion is not. This allows the first portion 11 and the second portion 12 to be in an operative state without affecting the other portion's operative state and providing energy to generate aerosol from the aerosol-generating article, regardless of whether one portion is in an operative state or not. Specifically, the delay circuit 4 can cause both the first portion 11 and the second portion 12 to be in an operative state and provide energy, or only one portion to be in an operative state while the other is in an inoperative state, or to cause one portion 11 and the second portion 12 to provide energy before it is in an operative state.

[0076] The power supply assembly includes a power supply 31, which may include any suitable power source, such as a DC source, such as a battery. In one embodiment, the power supply 31 is a lithium-ion battery. Alternatively, the power supply 31 may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium-cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery. The power supply 31 may also include a first output pole 33 and a second output pole 34, with the first portion 11 and the second portion 12 connected between the first output pole 33 and the second output pole 34. The power supply 31 provides power to the power-consuming element 1 via the first output pole 33 and the second output pole 34.

[0077] The aerosol generating device also includes a control component 32. The control component 32 may be provided with one or more control circuits having one or more controllers / processors, and the one or more control circuits may control the output of the power supply 31. For example, the control circuit may control the DC power supply to output AC current / AC voltage; or the control circuit may control the energy, power, or frequency output by the power supply 31 to the electrical element 1; or the control circuit may control the direction of the power output by the power supply 31 to the electrical element 1; or the control circuit may directly control the delay circuit 4, thereby affecting the operating state of the first part 11 and the second part 12; or the control circuit may not have a direct electrical connection with the delay circuit 4, or the control circuit may not be able to directly send control signals to the delay circuit 4. The control component 32 may not only control the operation of the power supply 31 and the electrical element 1, but may also control the operation of other components in the aerosol generating device. For example, the control circuit may determine whether the aerosol generating device is operational by checking the status of the components of the aerosol generating device.

[0078] The control circuit may include a gate-controlled switch 6. In one example, the gate-controlled switch 6 is associated with a mechanical switch, such as a pushbutton switch, a touch switch, a touchscreen switch, or a slide switch, or the gate-controlled switch 6 includes a mechanical switch. When the mechanical switch is triggered, or when the gate-controlled switch 6 is triggered, the control circuit connects the circuit between the electrical component 1 and the power supply 31, or connects the circuit between the electrical component 1 and the power supply 31. At this point, at least one of the first portion 11 and the second portion 12 can be in an operational state and capable of providing energy, or one of the first portion 11 and the second portion 12 can generate energy before the other. In one example, the gate-controlled switch 6 is a controlled switch controlled by a switch drive signal output by the control circuit. The control circuit can drive the gate-controlled switch 6 based on the switch drive signal, thereby connecting the circuit between the electrical component 1 and the power supply 31, causing at least one of the first portion 11 and the second portion 12 to be in an operational state and capable of providing energy, or causing one of the first portion 11 and the second portion 12 to generate energy before the other. For example, after the aerosol generating device is turned on, the control circuit can generate one or more switch drive signals after checking the status of the components of the aerosol generating device and determining that the aerosol generating device can be operated, or the controller in the control circuit can obtain one or more switch drive signals through other means, and then the control circuit can drive the gate-controlled switch tube 6 based on the switch drive signal.

[0079] In the embodiments shown in Figures 8-11, the gate-controlled switch tube 6 is disposed between the first output electrode 33 and the power supply 31, or the gate-controlled switch tube 6 is disposed between the second output electrode 34 and the electric eye 31. When the gate-controlled switch tube 6 is triggered or driven, the circuit between the electrical component 1 and the power supply 31 is conductive, that is, the circuit between the power supply 31 and the first output electrode 33 and the second output electrode 34 is conductive, so that the electrical component 1 can obtain the electricity it generates from the first output electrode 33 and the second output electrode 34.

[0080] In other embodiments, the gate-controlled switch tube 6 is disposed between the first output pole 33 and the power-consuming element 1, or the gate-controlled switch tube 6 is disposed between the second output pole 34 and the power-consuming element 1. When the gate-controlled switch tube 6 is triggered or driven, the circuit between the power-consuming element 1 and the power source 31 is connected, so that the power-consuming element 1 can obtain the power generated by the energy from the first output pole 33 and the second output pole 34.

[0081] The delay circuit 4 may be provided between the first portion 11 and the gate-controlled switch tube 6 , or the delay circuit may be provided between the second portion 12 and the gate-controlled switch tube.

[0082] In one embodiment, the delay circuit includes a unidirectional conduction switch, and the power supply 31 is configured to output power to the power-consuming element 1 and the unidirectional conduction switch through the first output pole 33 and the second output pole 34. The controller is configured to switch the direction in which the first output pole 33 and the second output pole 34 output power. The directions in which the first output pole 33 and the second output pole 34 output power are different, and the switching states of the unidirectional conduction switch are different. For example, when the direction in which the first output pole 33 and the second output pole 34 output power is a first direction, such as when the potential of the first output pole 33 is higher than the potential of the second output pole 34, the unidirectional conduction switch is turned on, and when the direction in which the first output pole 33 and the second output pole 34 output power is a second direction opposite to the first direction, such as when the potential of the first output pole 33 is lower than the potential of the second output pole 34, the unidirectional conduction switch is turned off.

[0083] When the unidirectional conducting switch is turned on, one of the first part 11 and the second part 12 can be short-circuited or disconnected, while the other can generate energy; or when the unidirectional conducting switch is turned off, one of the first part 11 and the second part 12 can be short-circuited or disconnected, while the other can generate energy.

[0084] As an example of this embodiment, the first portion 11 and the second portion 12 are connected in parallel between the first output pole 33 and the second output pole 34. The unidirectional conduction switch is connected in series with only one of the first portion 11 and the second portion 12, thereby being associated with only one of the first portion 11 and the second portion 12. Therefore, when the unidirectional conduction switch is turned off, the portion associated with the unidirectional conduction switch is disconnected and thus inoperative. When the unidirectional conduction switch is turned on, the portion associated with the unidirectional conduction switch is inoperative. The other portion not associated with the unidirectional conduction switch is unaffected by the unidirectional conduction switch being turned on or off.

[0085] As an example of this embodiment, the first portion 11 and the second portion 12 are connected in series between the first output pole 33 and the second output pole 34, and the unidirectional conducting switch is connected in parallel with only one of the first portion 11 and the second portion 12. Thus, the unidirectional conducting switch is associated with only one of the first portion 11 and the second portion 12. Therefore, when the unidirectional conducting switch is off, the portion associated with the unidirectional conducting switch is in an operational state. When the unidirectional conducting switch is on, the portion associated with the unidirectional conducting switch is short-circuited and therefore in an inoperative state. The other portion not associated with the unidirectional conducting switch is unaffected by the unidirectional conducting switch being on or off.

[0086] It should be noted that when the delay circuit includes a unidirectional conduction switch, and when the controller switches the unidirectional conduction switch between on and off by controlling the switching direction of the power output from the first output pole 33 and the second output pole 34, the controller may have no direct electrical connection with the unidirectional conduction switch, and the controller cannot directly send a control signal to the unidirectional conduction switch to drive it to be on or off.

[0087] Without affecting the state of the delay circuit by controlling the switching direction of the power output by the first output pole 33 and the second output pole 34, other methods can also be used to eliminate the direct electrical connection between the delay circuit and the controller, thereby preventing the controller from directly sending a control signal to the delay circuit.

[0088] For example, the delay circuit includes a capacitor C and a drive switch Q, the capacitor C is connected to the drive switch D, the capacitor C provides a drive voltage for the drive switch D, and the drive switch D is turned on or off when the drive voltage reaches a drive threshold, so that one of the first part 11 and the second part 12 is short-circuited or disconnected, and the other generates energy.

[0089] As an example, referring to FIG8 , the drive switch is a high-level drive switch Q. When the drive electrode of the drive switch Q has a high level, the drive switch Q is turned on. The anode terminal of the capacitor C can be connected to the output anode of the first output electrode 33 and the second output electrode 34 via a resistor R. The anode terminal of the capacitor C is also connected to the drive electrode of the drive switch Q, and the cathode terminal of the capacitor C is connected to the output cathode of the first output electrode 33 and the second output electrode 34. Therefore, when the line between the electrical component 1 and the power supply 31 is conductive, the output anode charges the capacitor C, causing the potential of the anode terminal of the capacitor C to gradually increase until it reaches the driving threshold level, turning on the drive switch Q. That is, as the potential of the anode terminal of the capacitor C gradually increases to the driving threshold level, the drive switch switches from being off to being on.

[0090] Alternatively, referring to FIG. 9 , the drive switch Q is a low-level drive switch. When the drive electrode of the drive switch Q has a low level, the drive switch Q is turned on. The anode terminal of the capacitor C can be connected to the output anode of the first output electrode 33 and the second output electrode 34 via a resistor R. The anode terminal of the capacitor C is also connected to the drive electrode of the drive switch Q, and the cathode terminal of the capacitor C is connected to the output cathode of the first output electrode 33 and the second output electrode 34. Therefore, when the line between the electrical component 1 and the power supply 31 is conductive, the output anode charges the capacitor C, causing the potential of the anode terminal of the capacitor C to gradually increase until it reaches a driving threshold level, causing the drive switch Q to be turned off. That is, as the potential of the anode terminal of the capacitor C gradually increases to the driving threshold level, the drive switch Q switches from on to off.

[0091] As an example, the first portion 11 and the second portion 12 are connected in parallel between the first output pole 33 and the second output pole 34, and the drive switch is connected in series with only one of the first portion 11 and the second portion 12. Thus, the drive switch is associated with only one of the first portion 11 and the second portion 12. Therefore, when the drive switch is turned off, the portion associated with the drive switch is disconnected and thus non-operating. When the drive switch is turned on, the portion associated with the drive switch is in operation. The other portion not associated with the drive switch is unaffected by the on / off state of the drive switch.

[0092] As an example, the first portion 11 and the second portion 12 are connected in series between the first output pole 33 and the second output pole 34, and the drive switch is connected in parallel with only one of the first portion 11 and the second portion 12. Thus, the drive switch is associated with only one of the first portion 11 and the second portion 12. Therefore, when the drive switch is turned off, the portion associated with the drive switch is in an operational state. When the drive switch is turned on, the portion associated with the drive switch is short-circuited and therefore in an inoperative state. The other portion not associated with the drive switch is unaffected by the on / off state of the drive switch.

[0093] In one embodiment, referring to Figures 10 and 11 , the delay circuit includes a drive switch Q. A controller is directly electrically connected to the drive switch Q and configured to drive the drive switch Q on or off. The controller can directly issue a control signal to the drive switch Q, causing the drive switch Q to be turned on or off in response to the control signal. When the drive switch is on, one of the first portion 11 and the second portion 12 is short-circuited or disconnected, and the other generates energy. Alternatively, when the drive switch Q is off, one of the first portion 11 and the second portion 12 is short-circuited or disconnected, and the other generates energy.

[0094] As an example of this embodiment, the controller can control the drive switch Q to remain on or off for a preset time, and at least one of the first part 11 and the second part 12 includes an induction coil for generating a changing magnetic field, so that at least one of the first part 11 and the second part 12 can generate magnetic energy.

[0095] Based on this, the aerosol-generating device may further include a susceptor capable of generating thermal energy in a changing magnetic field, wherein the susceptor is within the range of the changing magnetic field generated by the first portion 11 and / or the second portion 12. Alternatively, the aerosol-generating article may include a susceptor capable of generating thermal energy in a changing magnetic field, and when the aerosol-generating article is coupled to the aerosol-generating device, the susceptor in the aerosol-generating article is within the range of the changing magnetic field generated by the first portion 11 and / or the second portion 12.

[0096] In one embodiment, the first portion 11 and the second portion 12 are integrally formed.

[0097] In one embodiment, at least one of the first portion 11 and the second portion 12 includes a resistive heating element, or at least one of the first portion 11 and the second portion 12 includes an infrared heating element.

[0098] In one embodiment, the aerosol generating device further includes a accommodating cavity for accommodating at least a portion of the aerosol generating article, the first portion 11 and the second portion 12 are respectively arranged at different positions corresponding to the accommodating cavity, and along the direction of the airflow in the aerosol generating article, the first portion 11 is arranged downstream of the second portion 12.

[0099] As an example of this embodiment, the first portion 11 generates energy before the second portion 12.

[0100] As an example of this embodiment, in the axial direction of the accommodating cavity, the extension length of the first portion 11 is less than or equal to the extension length of the second portion 12 .

[0101] In one embodiment, in a first time period, the first portion 11 generates energy, and in a second time period, both the first portion 11 and the second portion 12 generate energy. The first time period may be before or after the second time period.

[0102] As an example of this embodiment, the first part 11 is configured such that the electric power in the first time period is greater than or equal to the electric power in the second time period. Alternatively, the first part 11 is configured such that the heating temperature in the first time period is greater than or equal to the heating temperature in the second time period.

[0103] As an example of this embodiment, the first portion 11 is configured such that the electric power in the second time period is less than or equal to the electric power in the second time period of the second portion 12. Alternatively, the heating temperature of the first portion 11 in the second time period is less than or equal to the heating temperature of the second portion 12 in the second time period.

[0104] As an example of this embodiment, the duration of the first time period is less than or equal to the duration of the second time period.

[0105] The present application will be described in more detail below with reference to a more specific current schematic diagram.

[0106] The control component 32 may further include a circuit board, and the first output pole 33 and the second output pole 34 may be disposed on the circuit board.

[0107] The power supply component 3 is configured to output power to the electrical element 1 through the first output pole 33 and the second output pole 34. The control component 32 controls the energy, electric power or frequency output by the power supply 31 to the electrical element 1 by controlling the power output by the power supply 31 to the first output pole 33 and the second output pole 34.

[0108] Referring to Figures 2-7 , the aerosol generating device includes a first circuit 35, a second circuit 36, and a third circuit 37. Both the first circuit 35 and the third circuit 37 are connected to the second circuit 36. The first portion 11 is disposed on the first circuit 35, and the second portion 12 is disposed on the third circuit 37. As shown in Figure 3 , the first circuit 35 and the third circuit 37 are connected in parallel between the first output pole 33 and the second output pole 34 of the power supply assembly 3; alternatively, as shown in Figure 5 , the first circuit 35 and the third circuit 37 are connected in series between the first output pole 33 and the second output pole 34 of the power supply assembly 3.

[0109] The delay circuit 4 can be associated only with the third line 37. The control state of the delay circuit 4 includes a first state and a second state. One of the first state and the second state is a conductive associated line, and the other is a cutoff associated line. The control state of the delay circuit 4 can be controlled to control the third line 37 where the second part 12 is located to be open or short-circuited, thereby controlling the working state of the second part 12.

[0110] When the delay circuit 4 is associated only with the third line 37 and the power supply 31 is outputting power through the first and second output poles 33 and 34, if the delay circuit 4 electrically connects the third line 37, the second portion 12 can draw power from the first and second output poles 33 and 34 and enter an operating state. Simultaneously, when the third line 37 is electrically connected, the first portion 11, which is not associated with the delay circuit 4, can also draw power from the first and second output poles 33 and 34 and enter an operating state. If the delay circuit 4 short-circuits or opens the third line 37, the first portion 11 is unaffected by the delay circuit 4 and can still draw power from the first and second output poles 33 and 34 and enter an operating state. However, the short-circuit or open-circuit of the third line 37 renders the second portion 12 non-operating. Therefore, the number of hardware components in the aerosol generating device is small, and the interconnection and arrangement between them are simple, which helps reduce costs and energy consumption in the circuit.

[0111] In one embodiment, referring to Figures 2, 3, and 6, the first line 35 is connected to the first output pole 33, the second line 36 is connected to the second output pole 34, and the third line 37 is connected to the first output pole 33 through at least a portion of the delay circuit 4. Thus, at least a portion of the delay circuit 4 is connected in series with the third line 37 / the second portion 12. Therefore, when the delay circuit 4 is in the on-link state, the third line 37 is turned on, and the second portion 12 is in an operating state. When the delay circuit 4 is in the off-link state, the third line 37 is turned off, and the second portion 12 is in a non-operating state.

[0112] It should be noted that other circuit settings and connection methods can also be used to make the circuit where the second part is located conductive when the delay circuit is in the conductive associated circuit state, and the circuit where the second part is located disconnected when the delay circuit is in the cutoff associated circuit state.

[0113] In one embodiment, referring to Figures 4, 5, and 7, the first line 35 is connected to the first output pole 33, the third line 37 is connected to the second output pole 34, and the second line 36 is connected to the second output pole 34 through at least a portion of the delay circuit 4. As a result, at least a portion of the delay circuit 4 is connected in parallel with the third line 37 / the second portion 12. Therefore, when the delay circuit 4 is in the on-link state, the third line 37 is short-circuited, and the second portion 12 is in a non-operating state. When the delay circuit 4 is in the off-link state, the third line 37 is connected, and the second portion 12 is in an operating state.

[0114] It should be noted that other circuit settings and connection methods can also be used to short-circuit the circuit where the second part is located when the delay circuit is in the state of conducting the associated circuit, and conduct the circuit where the second part is located when the delay circuit is in the state of cutting off the associated circuit.

[0115] Based on the first aspect of the present application, at least a portion of the delay circuit 4 is in series with the second portion 12. When the delay circuit 4 is in the state of conducting the associated circuit, the second portion 12 is conductive and in an operational state. When the delay circuit 4 is in the state of blocking the associated circuit, the circuit in which the second portion 12 resides is disconnected, rendering the second portion 12 in an inoperative state. For example, the delay circuit 4 includes a unidirectional conduction switch, and the power supply assembly 3 is configured to switch the direction in which power is output from the first output pole 33 to the second output pole 34. Thus, by switching the direction in which power is output from the first output pole 33 to the second output pole 34, the unidirectional conduction switch can be controlled to conduct or cut off, thereby rendering the second portion 12 in an operational or inoperative state.

[0116] According to the second aspect of the present application, at least a portion of the delay circuit 4 is connected in parallel with the second portion 12. When the delay circuit 4 is in the connected state, the circuit in which the second portion 12 resides is short-circuited, rendering the second portion 12 in an inoperative state. When the delay circuit 4 is in the blocked state, the circuit in which the second portion 12 resides is connected, rendering the second portion 12 in an operative state. For example, the delay circuit 4 includes a unidirectional conduction switch, and the power supply assembly 3 is configured to switch the direction in which power is output from the first output pole 33 to the second output pole 34. Thus, by switching the direction in which power is output from the first output pole 33 to the second output pole 34, the unidirectional conduction switch can be controlled to be on or off, thereby rendering the second portion 12 in an operative state or in an inoperative state.

[0117] A unidirectional conductive switch is a switch that allows only one-way conduction of the circuit in which it is located. For example, when the potential of the first output electrode 33 is higher than the potential of the second output electrode 34, the direction in which the first and second output electrodes 33 and 34 output power is in a first direction, and the unidirectional conductive element is conductive. When the potential of the first output electrode 33 is lower than the potential of the second output electrode 34, the direction in which the first and second output electrodes 33 and 34 output power is in a second direction different from the first direction, and the unidirectional conductive element is in a cutoff state.

[0118] The unidirectional conductive element includes, but is not limited to, a diode.

[0119] Based on the third aspect of the present application, at least a part of the delay circuit 4 is in series with the second part 12, the power supply 31 in the power supply component 3 outputs power to the power-consuming element 1 through the first output pole 33 and the second output pole 34, the control component 32 is connected to the delay circuit 4, and the control component 32 is configured to drive the delay circuit 4 to be in the on-associated line state or in the off-associated line state. At this time, the delay circuit 4 or the driving switch in the delay circuit 4 may include a transistor, and suitable transistors include but are not limited to: a triode, a field effect transistor (field effect transistor is divided into PMOS transistor and NMOS transistor), a thyristor (controlled silicon) and an IGBT [IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of a (Bipolar Junction Transistor, BJT) bipolar triode and an insulated gate field effect transistor (Metal Oxide Semiconductor, MOS)] at least one.

[0120] Therefore, when the delay circuit 4 is in the connected state, the second portion 12 is turned on and in operation. When the delay circuit 4 is turned off, the circuit containing the second portion 12 is disconnected, rendering the second portion in an inoperative state. Furthermore, the control component 32 can be used to drive the delay circuit 4 to either the connected state or the disconnected state, thereby placing the second portion 12 in either the operational or inoperative state. Based on the third aspect, the delay circuit 4 being in the connected state or the disconnected state is not caused by a change in the direction of power output from the first output electrode 33 and the second output electrode 34.

[0121] Based on the fourth aspect of the present application, at least a part of the delay circuit 4 is in parallel with the second part 12, the power supply 31 in the power supply component 3 outputs power to the electrical element 1 through the first output pole 33 and the second output pole 34, the control component 32 is connected to the delay circuit 4, and the control component 32 is configured to drive the delay circuit 4 to be in the on-associated line state or in the off-associated line state. At this time, the delay circuit 4 or the driving switch may include a transistor.

[0122] Thus, when the delay circuit 4 is in the on-link state, the line containing the second portion 12 is short-circuited, rendering the second portion non-operating. When the delay circuit 4 is in the off-link state, the line containing the second portion 12 is conductive, rendering the second portion 12 operational. Furthermore, the control component 32 can be used to drive the delay circuit 4 to either the on-link state or the off-link state, thereby rendering the second portion 12 operational or non-operating. Based on the fourth aspect, the on-link state or the off-link state of the delay circuit 4 is not caused by a change in the direction in which the power is output by the first output electrode 33 and the second output electrode 34.

[0123] According to the fifth aspect of the present application, at least a portion of the delay circuit 4 is connected in series or in parallel with the second portion 12. The drive switch in the delay circuit 4 has a conduction voltage. When the voltage across the drive switch is greater than the conduction voltage, the delay circuit 4 is in a conduction-associated circuit state. When the voltage across the drive switch is less than the conduction voltage, the delay circuit 4 is in a cutoff-associated circuit state. The control circuit in the control component 32 can control the voltage across the drive switch, thereby controlling whether the delay circuit 4 is conducted or cutoff. Alternatively, the delay circuit 4 can control the voltage across the drive switch itself.

[0124] Based on the sixth aspect of the present application, at least a part of the delay circuit 4 is connected in series or in parallel with the second part 12, and the driving switch in the delay circuit 4 has a driving pole. The delay circuit 4 can automatically make the voltage or current on the driving pole reach the threshold value for driving the driving pole, thereby making the delay circuit 4 in the state of conducting the associated line or in the state of cutting off the associated line.

[0125] Based on any one of the first to sixth aspects of the present application, at least one of the first portion 11 and the second portion 12 is configured to generate thermal energy.

[0126] As an example, at least one of the first portion 11 and the second portion 12 includes a resistive heating element.

[0127] The resistive heating element comprises a resistive material that is capable of generating Joule heat when conducting electricity. Suitable resistive materials include, but are not limited to, semiconductors, such as doped ceramics, conductive ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic materials and metal materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel, Constantan, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys, as well as superalloys based on nickel, iron, and cobalt, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0128] Resistive heating elements include MESH nets, resistance coils, resistance heating tracks or resistance coatings.

[0129] The resistive heating element includes an infrared electric heating coating, which can generate heat energy when powered on, and then generate infrared rays of a certain wavelength. When the wavelength of the infrared ray matches the absorption wavelength of the aerosol-forming matrix, the energy of the infrared ray is easily absorbed by the aerosol-forming matrix. In the embodiment of the present application, the wavelength of the infrared ray is not limited, and it can be an infrared ray of 0.75μm to 1000μm, and optionally a far infrared ray of 1.5μm to 400μm. The infrared electric heating coating can be optionally made by fully mixing far-infrared electric heating ink, ceramic powder and inorganic adhesive, and then printing it on the outer surface of the substrate, and then drying and curing it for a certain period of time. The thickness of the infrared electric heating coating is 30μm-50μm; of course, the infrared electric heating coating can also be made by mixing tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride and anhydrous copper sulfate in a certain proportion and then coating it on the outer surface of the substrate; or it can be a silicon carbide ceramic layer, a carbon fiber composite layer, a zirconium-titanium oxide ceramic layer, a zirconium-titanium nitride ceramic layer, or a silicon carbide ceramic layer. One of the following ceramic layers, zirconium-titanium boride ceramic layers, zirconium-titanium carbide ceramic layers, iron-based oxide ceramic layers, iron-based nitride ceramic layers, iron-based boride ceramic layers, iron-based carbide ceramic layers, rare earth-based oxide ceramic layers, rare earth-based nitride ceramic layers, rare earth-based boride ceramic layers, rare earth-based carbide ceramic layers, nickel-cobalt-based oxide ceramic layers, nickel-cobalt-based nitride ceramic layers, nickel-cobalt-based boride ceramic layers, nickel-cobalt-based carbide ceramic layers or high-silicon molecular sieve ceramic layers; the infrared electric heating coating can also be a coating of other existing materials.

[0130] As an example, the first line 35 in which the first portion 11 is located is configured to remain conductive when the power supply assembly 3 outputs power through the first output pole 33 and the second output pole 34. Thus, the first portion 11 can continuously generate heat energy when the power supply assembly 3 outputs power through the first output pole 33 and the second output pole 34. Depending on whether the delay circuit 4 is in the conductive or blocked state of the associated line, when the power supply assembly 3 outputs power through the first output pole 33 and the second output pole 34, the second portion 12 can generate heat energy only for a portion of the time, continuously, or not at all.

[0131] For example, when the power supply component 3 outputs power through the first output pole 33 and the second output pole 34 in the first time period and the second time period, the first part 11 is configured to be electrically conductive in both the first time period and the second time period, so that the first part 11 is in a working state in the first time period and the second time period, that is, the first part 11 can generate heat in both the first time period and the second time period.

[0132] The second portion 12 can be configured to be electrically conductive and in an operating state during a second time period, so that the second portion 12 can be in an inoperative state during a first time period and in an operating state during a second time period to generate heat. The second time period can be after the first time period, so that the first portion 11 can generate heat energy before the second portion.

[0133] In one embodiment, the upper end of the aerosol-generating device is provided with an insertion port for inserting the aerosol-generating article into the receiving chamber. With the insertion port located at the upper end of the aerosol-generating device as a reference, the first portion 11 is positioned above the second portion 12. The spacing between the first portion 11 and the insertion port is smaller than the spacing between the second portion 12 and the insertion port. The heat energy generated by the first portion 11 and the second portion 12 is used to heat different portions of the aerosol-generating article 2, respectively. To shorten the time it takes for a user to inhale the first aerosol produced by the aerosol-generating article, the first portion 11, positioned above the second portion 12, can be enabled to operate and generate heat first. Subsequently, the first portion 11 and the second portion can be enabled to operate and generate heat simultaneously.

[0134] As an example, the first portion 11 is configured such that the electrical power during the first time period is greater than or equal to the electrical power during the second time period. Therefore, the temperature of the first portion 11 during the first time period, or the amount of heat released per unit time during the first time period, may be greater than the temperature of the first portion 11 during the second time period, or the amount of heat released per unit time during the second time period; alternatively, the first portion 11 may have approximately the same heating temperature or release approximately the same amount of heat per unit time during the first and second time periods.

[0135] Specifically, in the embodiment shown in Figure 3, the first part 11 and the second part 12 are connected in parallel between the first output pole 33 and the second output pole 34, so the voltage applied to both ends of the first part 11 by the first output pole 33 and the second output pole 34 in the first time period can be greater than or equal to the voltage applied to both ends of the first part 11 by the first output pole 33 and the second output pole 34 in the second time period; or, the frequency, amplitude and duty cycle of the voltage pulses provided by the first output pole 33 and the second output pole 34 to the first part 11 in the first time period can be greater than or equal to the frequency, amplitude and duty cycle of the voltage pulses provided to the first part 11 by the first output pole 33 and the second output pole 34 in the second time period.

[0136] In the embodiment shown in Figure 5, the first part 11 and the second part 12 are connected in series between the first output pole 33 and the second output pole 34, so the current provided to the first part 11 by the first output pole 33 and the second output pole 34 in the first time period can be greater than or equal to the current provided to the first part 11 by the first output pole 33 and the second output pole 34 in the second time period; or, the frequency, amplitude and duty cycle of the current pulses provided to the first part 11 by the first output pole 33 and the second output pole 34 in the first time period can be greater than or equal to the frequency, amplitude and duty cycle of the current pulses provided to the first part 11 by the first output pole 33 and the second output pole 34 in the second time period.

[0137] When the temperature of the first part 11 in the first time period or the heat released per unit time in the first time period is greater than the temperature of the first part 11 in the second time period or the heat released per unit time in the second time period, it is more conducive to accelerating the speed at which the aerosol generating product produces the first aerosol, which is beneficial for the user to inhale the first aerosol in a shorter time, and at the same time can prevent the aerosol generating product corresponding to the first part 11 from being burnt in the second time period.

[0138] As an example, the first portion 11 is configured such that the electric power during the second time period is less than or equal to the electric power during the second time period of the second portion 12. Thus, during the second time period, the temperature of the first portion 11 or the amount of heat released per unit time is less than or equal to the temperature of the second portion 12 or the amount of heat released per unit time.

[0139] For example, as shown in Figure 3, the first part 11 and the second part 12 are connected in parallel between the first output pole 33 and the second output pole 34, and the power supply 31 can adopt a constant current source, that is, the total current value output by the first output pole 33 and the second output pole 34 in the first time period can be equal to the total current value output in the second time period. As a result, the first part 11 is shunted by the second part 12 in the second time period, resulting in a decrease in the current flowing through the first part 11 and a decrease in electric power.

[0140] For example, as shown in Figure 3, the first part 11 and the second part 12 are connected in parallel between the first output pole 33 and the second output pole 34, and the power supply 31 can adopt a constant voltage source, that is, the total value of the voltage output by the first output pole 33 and the second output pole 34 in the first time period can be equal to the total value of the voltage output in the second time period. Therefore, in the first time period and the second time period, the voltage at both ends of the first part 11 can remain unchanged, so that in the first time period and the second time period, the first part 11 can have approximately the same electric power.

[0141] For example, as shown in Figure 5, the first part 11 and the second part 12 are connected in series between the first output pole 33 and the second output pole 34, and the power supply 31 can adopt a constant voltage source, that is, the total value of the voltage output by the first output pole 33 and the second output pole 34 in the first time period can be equal to the total value of the voltage output in the second time period. Therefore, the first part 11 is divided by the second part 12 in the second time period, resulting in a decrease in voltage across the first part 11 and a decrease in electric power.

[0142] For example, as shown in Figure 5, the first part 11 and the second part 12 are connected in series between the first output pole 33 and the second output pole 34, and the power supply 31 can adopt a constant current source, that is, the total value of the current output by the first output pole 33 and the second output pole 34 in the first time period can be equal to the total value of the current output in the second time period. Therefore, in the first time period and the second time period, the current flowing through the first part 11 can remain unchanged, so that in the first time period and the second time period, the first part 11 can have approximately the same electric power.

[0143] As an example, the duration of the first time period is less than or equal to the duration of the second time period. After the aerosol-generating article quickly generates the first aerosol for inhalation by the user, the first time period may end, and the remaining time for heating the aerosol-generating article may be the second time period, but is not limited thereto.

[0144] In which, when the first part 11 and the second part 12 can be arranged along the axial direction of the accommodating cavity, or the first part 11 and the second part 12 can have no overlap in the radial direction of the accommodating cavity, the length of the first part 11 along the axial direction of the accommodating cavity can be less than or equal to the length of the second part 12.

[0145] It should be noted that, in other embodiments, the first portion may overlap with the second portion in the radial direction of the accommodating cavity.

[0146] As an example, the first part 11 and the second part 12 are arranged around the accommodating cavity, so that when at least a portion of the aerosol generating article 2 is combined with the accommodating cavity, the first part 11 and the second part 12 surround at least a portion of the aerosol generating article 2, so that the first part 11 and the second part 12 can heat the aerosol generating article 2 outside the aerosol generating article 2.

[0147] As an example, the first part 11 and the second part 12 are arranged in the accommodating cavity. When the aerosol generating article 2 is at least partially combined with the accommodating cavity, the first part 11 and the second part 12 can enter the aerosol generating article 2, so that the first part 11 and the second part 12 can heat the aerosol generating article 2 inside the aerosol generating article 2.

[0148] As an example, the aerosol generating device also includes a temperature sensor 5, which is combined with the first part 11 or the second part 12 for sensing the temperature of the first part 11 or the second part 12, and the control component 32 is configured to control the electric power provided by the power supply component 3 to the electrical element 1 based on the sensing result of the temperature sensor 5.

[0149] That is, based on the sensing results of the temperature sensor 5, in the first time period, the control component 32 can make the current / voltage / electric power provided by the power supply 31 to the electrical element 1 through the first output pole 33 and the second output pole 34 constant or variable, so as to ensure that the aerosol generating product 2 has a suitable heating temperature and can quickly generate the first aerosol without being burnt or burned, and at the same time prevent the aerosol temperature from being too high and scalding the mouth.

[0150] Alternatively, based on the sensing results of the temperature sensor 5, the control component 32 can enable the power supply 31 to provide the current / voltage / electric power provided to the electrical element 1 through the first output pole 33 and the second output pole 34 to be approximately equal in the first time period and the second time period, so as to ensure the consistency of the aerosol generated by the aerosol generating article 2 in each puff.

[0151] Alternatively, based on the sensing results of the temperature sensor 5, the control component 32 can make the current / voltage / electric power provided to the electrical element 1 by the power supply 31 through the first output pole 33 and the second output pole 34 in the first time period greater than or less than the current / voltage / electric power provided to the electrical element 1 by the power supply 31 through the first output pole 33 and the second output pole 34 in the second time period.

[0152] Alternatively, based on the sensing results of the temperature sensor 5, the control component 32 can cause the current / voltage / electric power provided by the power supply 31 to the electrical element 1 through the first output pole 33 and the second output pole 34 to vary within a first time period and / or within a second time period to ensure the stability, continuity and consistency of the aerosol generated by the aerosol generating product 2 in each puff, and prevent the aerosol generating product 2 from being burnt or burned.

[0153] When the first portion 11 is disposed above the second portion 12, and the first portion 11 generates heat energy during both the first time period and the second time period, and the second portion 12 generates heat energy during the second time period, and the second time period is later than the first time period, the temperature sensor 5 can be coupled to the first portion 11. The control component 32 can adjust the magnitude and direction of the power output by the power supply 31 through the first output pole 33 and the second output pole 34 based on the temperature of the first portion 11.

[0154] When the temperature sensor 5 is combined with the first part 11, the control component 32 can control the end of the first time period and control the entry into the second time period based on whether the first part 12 reaches the preset temperature or based on the time the first part 12 reaches and maintains the preset temperature.

[0155] It should be noted that the control component 32 may also control the power output direction of the first output electrode 33 and the second output electrode 34, or control the control state of the delay circuit 4, based on other judgment criteria, such as whether the duration of the first time period reaches a preset time period, to end the first time period and enter the second time period. The second time period may be entered immediately after the first time period ends.

[0156] Based on the third aspect or the fourth aspect of the present application, at least one of the first portion 11 and the second portion 12 can be configured to generate magnetic energy. The power supply component 3 is configured to provide alternating current (AC) to the first portion 11 and the second portion 12, where the AC power includes AC current or AC voltage, so that the first portion 11 and the second portion 12 can generate a varying magnetic field.

[0157] In one example, the first portion 11 and / or the second portion 12 can generate a variable magnetic field between 1 and 30 MHz, for example, between 2 and 10 MHz, for example, between 5 and 7 MHz. In one example, the first portion 11 and / or the second portion 12 can generate a variable magnetic field having a field strength (H field) between 1 and 5 kA / m, for example, between 2 and 3 kA / m, for example, approximately 2.5 kA / m. With reference to FIG. 6 , the first portion 11 and / or the second portion 12 can each be configured as a spiral coil.

[0158] In one example, the aerosol-generating device may further include a susceptor capable of generating heat in a changing magnetic field. The susceptor may be disposed around the receiving cavity so that the susceptor can heat the aerosol-generating article 2 from the outside, or at least partially disposed within the receiving cavity so that the susceptor can heat the aerosol-generating article 2 from the inside. The susceptor may comprise metal or carbon. Carbon includes graphite, graphite alloys, graphene, and the like. In one example, the susceptor may comprise a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In one example, the susceptor comprises a nickel-iron alloy. In one embodiment, the susceptor comprises 400 series stainless steel, which includes 410, 420, or 430 grade stainless steel.

[0159] In one example, a susceptor is disposed within the aerosol-generating article 2 .

[0160] In which, regardless of whether the receptor is incorporated into the aerosol generating device or the aerosol generating article 2, the receptor corresponding to the first part 11 and the receptor corresponding to the second part 12 can be an integral structure, so that a portion of the receptor can be set within the changing magnetic field range generated by the first part 11, and a portion can be set within the changing magnetic field range generated by the second part 12; or, the receptor corresponding to the first part 11 and the receptor corresponding to the second part 12 can be two independent structures, and the receptor corresponding to the first part 11 and the receptor corresponding to the second part 12 are respectively located in the magnetic field ranges generated by the first part 11 and the second part 12.

[0161] Therefore, the heat energy generated by the susceptors corresponding to the first portion 11 and the heat energy generated by the susceptors corresponding to the second portion 12 are respectively used to heat different parts of the aerosol-generating article 2 .

[0162] As an example, referring to Figures 6 and 7, the first part 11 can be configured to be electrically conductive in both the first time period and the second time period, so that the first part 11 is in a working state in both the first time period and the second time period, that is, the sensor corresponding to the first part 11 can generate heat in both the first time period and the second time period.

[0163] The second portion 12 may be configured to be electrically conductive and in working condition in a second time period, and the sensor corresponding to the second portion 12 may generate heat in the second time period, which may be after the first time period.

[0164] As an example, the first portion 11 is disposed above the second portion 12 , and at least a portion of the susceptor corresponding to the first portion is disposed above the susceptor corresponding to the second portion 12 .

[0165] As an example, the aerosol generating device further includes a temperature sensor 5 , which is coupled to the receptor and is used to sense the temperature of the receptor. The control component is configured to control the electric power provided by the power supply component 3 to the electrical element 1 based on the sensing result of the temperature sensor 5 .

[0166] More specifically, the temperature sensor 5 can be combined with a sensor corresponding to the first part 11 to regulate the output power of the power supply 31 through the first output pole 33 and the second output pole 34 based on the temperature of the sensor, or to end the first time period and enter the second time period based on the temperature of the sensor.

[0167] For example, when the temperature sensor 5 detects that the temperature on the receptacle corresponding to the first portion 11 reaches a preset temperature, or when the control component learns, based on the detection result of the temperature detector 5, that the temperature on the receptacle corresponding to the first portion 11 maintains the preset temperature for a preset period of time, the control component may control the drive switch Q to be turned on or off, thereby controlling the end of the first time period and the entry into the second time period.

[0168] In one embodiment, the delay circuit 4 is a component of the electrical component 1. In one embodiment, the delay circuit 4 is a component of the aerosol generating device, which can be separated from the electrical component 1 or can exist independently of the electrical component 1.

[0169] In one embodiment, the aerosol generating device includes a flexible circuit board, wherein at least one of the first circuit, the second circuit, and the third circuit is disposed on the flexible circuit board, and the delay circuit is disposed on the flexible circuit board. More specifically, the flexible circuit board is connected to a control assembly, thereby allowing the delay circuit to exist independently of the control assembly. More specifically, the first output electrode and the second output electrode can be disposed on the control assembly, i.e., the first output electrode and the second output electrode can exist independently of the flexible circuit board. In other embodiments, the control assembly is part of the flexible circuit board and can be flexible.

[0170] In one embodiment, the first output electrode, the second output electrode and the delay circuit are all arranged on the control component.

[0171] Based on the seventh aspect of the present application, the electrical component 1 includes a first part 11 and a second part 12, both of which are mesh-shaped, for example, the first part 11 is a mesh structure, or a tubular structure with mesh holes, and the second part 12 is a mesh structure, for example, the second part 11 is a mesh structure, or a tubular structure with mesh holes.

[0172] The first part 11 and the second part 12 can be connected to each other. The connecting section connecting the first part 11 and the second part 12 can be made of the same material as the first part 11 and / or the second part 12. The connecting section can be a strip-shaped structure extending along the circumference of the accommodating cavity.

[0173] After the first portion 11 and the second portion 12 are connected to each other, there may be no clear dividing line between the first portion 11 and the second portion 12. Of course, the possibility of a clear dividing line is not excluded.

[0174] The first portion 11 and the second portion 12 may both be components of the electrical component 1, and the first portion 11 and the second portion 12 may each constitute a portion of the electrical component 1. In the embodiments shown in Figures 2 and 4, the electrical component 1 is generally a mesh when laid out, and the mesh-shaped first portion 11 and the mesh-shaped second portion 22 each occupy a portion of the mesh.

[0175] The first portion 11 and the second portion 12 may be integrally formed.

[0176] When powered, the first portion 11 and the second portion 12 can provide heat to enable the aerosol-generating article 2 to generate aerosol. In the seventh aspect of the present application, only one of the first portion 11 and the second portion 12 is connected in series or in parallel with the delay circuit 4. Thus, when the power supply assembly 3 simultaneously supplies power to the first portion 11 and the second portion 12, the first portion 11 and the second portion 12 do not generate heat simultaneously during a predetermined time period. It should be noted that when the power supply assembly 3 simultaneously supplies power to the first portion 11 and the second portion 12, due to the presence of the delay circuit 4, the first portion 11 and the second portion 12 cannot simultaneously receive power during a predetermined time period. Consequently, the first portion 11 and the second portion 12 do not simultaneously generate heat during a predetermined time period.

[0177] A controller and a gate-controlled switch tube 6 can be set in the aerosol generating device. The controller can drive the gate-controlled switch tube 6 to be turned on or off based on the switch drive signal. When the gate-controlled switch tube 6 is turned on or off, the line between the electrical element 1 and the power supply 31 in the power supply component 3 is connected, so that the power supply component 3 can simultaneously provide power to the first part 11 and the second part 12, and when the line between the electrical element 1 and the power supply 31 in the power supply component 3 is connected, at least one of the first part 11 and the second part 12 can generate heat.

[0178] According to an embodiment of the seventh aspect of the present application, in a first time period, the first portion 11 and the second portion 12 generate heat simultaneously, and in a second time period, only the first portion 11 generates heat. The first time period is before the second time period.

[0179] Since the first time period is before the second time period, after the first part 11 and the second part 12 generate heat simultaneously for a period of time, the first part 11 of the first part 11 and the second part 12 generates heat alone again, while the second part 12 pauses or stops generating heat.

[0180] For example, during a first time period, after the first and second portions 11, 12 simultaneously generate heat for a period of time, a significant amount of heat accumulates in the aerosol-generating article 2. If the first and second portions 11, 12 continue to simultaneously generate a large amount of heat, this may cause at least partial overheating of the aerosol-generating article 2, or problems such as burning or burning. In this case, the first time period may be terminated and a second time period may be entered, where only the first portion 11 of the first and second portions 11, 12 is allowed to generate heat, while the second portion 11 is suspended or stopped from generating heat, thereby allowing some of the accumulated heat in the aerosol-generating article 2 to be released. Compared to directly stopping the first and second portions 11, 12 from generating heat simultaneously, only allowing the first portion 11 to generate heat can ensure that the aerosol-generating article 2 produces an aerosol with a uniform taste during both the first and second time periods without significantly reducing the amount of aerosol generated, thereby helping to ensure consistent puffs.

[0181] If the aerosol-generating article 2 is not completely heated by the end of the second time period, the first portion 11 and the second portion 12 may be simultaneously heated again in a third time period following the second time period. Then, only the first portion 11 of the first portion 11 and the second portion 12 may be heated in a fourth time period following the third time period. This process is repeated in this manner until the aerosol-generating article 2 is completely heated.

[0182] The total resistance per unit area of ​​the first portion 11 can be made smaller than the total resistance per unit area of ​​the second portion 12, or the heat generated per unit area of ​​the first portion 11 can be made smaller than the heat generated per unit area of ​​the second portion 12. For example, the meshes of the first portion 11 can be made larger than the meshes of the second portion 12. That is, the meshes in the first portion 11 can have a larger hole area than the meshes in the second portion 12, or the width of the walls defining the meshes in the first portion 11 can be larger than the width of the walls defining the meshes in the second portion 12, or the cross-sectional area of ​​the walls defining the meshes in the first portion 11, through which current passes, can be larger than the cross-sectional area of ​​the walls defining the meshes in the second portion 12.

[0183] Based on this, as an example, the first portion 11 and the second portion 12 are respectively disposed at different positions corresponding to the accommodating cavity, and along the direction of airflow in the aerosol-generating article 2, the first portion 11 can be disposed downstream of the second portion 12. In other words, during a first time period, the first portion 11 and the second portion 12 generate heat simultaneously, and during the first time period, the amount of heat generated per unit time or per unit area by the first portion 11 can be less than the amount of heat generated per unit time or per unit area by the second portion 12. During a second time period, the downstream first portion 11 continues to generate heat, while the second portion 12 does not generate heat during the second time period.

[0184] In another embodiment of the seventh aspect of the present application, in a first time period, only the first part 11 generates heat in the first and second parts 12, and in a second time period, both the first and second parts 11 and 12 generate heat simultaneously. The first time period is before the second time period.

[0185] Since the first time period is before the second time period, after only the first part 11 generates heat for a period of time, the first part 11 and the second part 12 generate heat at the same time.

[0186] For example, in a first time period, after only the first portion 11 of the first and second portions 11, 12 generates heat for a period of time, sufficiently preheating the corresponding area of ​​the aerosol-generating article 2, or quickly generating the first aerosol for the user to inhale, if only the first portion 11 of the first and second portions 11, 12 continues to generate heat while the second portion 12 continues to not generate heat, this may affect further baking of the aerosol-generating article 2, resulting in the aerosol-generating article 2 being unable to generate sufficient aerosol for the user to inhale, or causing local overheating, burning, or combustion of the aerosol-generating article 2. In this case, the first time period may be terminated and a second time period may be entered, in which the first and second portions 11, 12 are simultaneously generated to heat the aerosol-generating article 2 more evenly and comprehensively, and to enable the aerosol-generating article 2 to generate aerosol over a wider range. Compared with allowing only the second part 12 of the first part 11 and the second part 12 to generate heat in the second time period, the first part 11 continuing to generate heat in the second time period can assist or help the second part 12 to heat the aerosol generating article 2, or can keep the corresponding area of ​​the aerosol generating article 2 warm, prevent the airflow in the corresponding area from being too low in temperature, and help to fully heat the corresponding area.

[0187] If the heating of the aerosol-generating article 2 is not complete by the end of the second time period, only the first portion 11 of the first portion 11 and the second portion 12 may be caused to generate heat in a third time period following the second time period. Then, the first portion 11 and the second portion 12 may be caused to generate heat simultaneously again in a fourth time period following the third time period. This process is repeated in this manner until the heating of the aerosol-generating article 2 is complete.

[0188] The total resistance per unit area of ​​the first portion 11 can be greater than or equal to the total resistance per unit area of ​​the second portion 12 , or the heat generated per unit area of ​​the first portion 11 can be greater than or equal to the heat generated per unit area of ​​the second portion 12 .

[0189] For example, the meshes of the first portion 11 and the meshes of the second portion 12 may be made equal in size, or the mesh walls of the first portion 11 may be smaller than the meshes of the second portion 12. That is, the mesh area of ​​the first portion 11 may be smaller than or equal to the mesh area of ​​the second portion 12, or the width of the walls defining the meshes in the first portion 11 may be smaller than or equal to the width of the walls defining the meshes in the second portion 12, or the cross-sectional area of ​​the walls defining the meshes in the first portion 11 through which current passes may be smaller than or equal to the cross-sectional area of ​​the walls defining the meshes in the second portion 12 through which current passes.

[0190] Based on this, as an example, the first portion 11 and the second portion 12 are respectively disposed at different positions corresponding to the accommodating cavity, and the first portion 11 can be disposed downstream of the second portion 12 along the direction of airflow in the aerosol-generating article 2. In other words, during a first time period, only the first portion 11 of the first and second portions 11, 12, generates heat. Under the heat generated by the first portion 11, the corresponding region of the aerosol-generating article 2 is preheated, or the corresponding region is able to quickly generate the first aerosol. During a second time period, the second portion located upstream generates heat, while the first portion 11 located downstream continues to generate heat. Furthermore, during the second time period, the amount of heat generated per unit time or per unit area by the first portion 11 can be greater than or equal to the amount of heat generated per unit time or per unit area by the second portion 12. Of course, the power provided by the power supply assembly 3 can be adjusted so that during the second time period, the amount of heat generated per unit time or per unit area by the first portion 11 is less than or equal to the amount of heat generated per unit time or per unit area by the second portion 12.

[0191] In the above-mentioned aerosol generating device, when the gate-controlled switch tube uses the circuit between the electrical element and the power supply to be turned on, one of the first part and the second part can generate energy before the other. Compared with the existing method in which the controller generates a control signal and uses the circuit between the electrical element and the power supply to be turned on, and then the controller generates a control signal to control one of the first part and the second part to generate energy before the other, not only is the control method and hardware structure simpler, but the energy consumption required is also lower, which can effectively reduce the production and use costs.

[0192] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
