[0061] Reference to "embodiments" herein means that the features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0062] 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 a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be one or more central elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0063] One embodiment of the present application provides an aerosol generating device, which is a device that is coupled or interacts with an aerosol generating article 2 to form an inhalable aerosol.

[0064] 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 an embodiment, the aerosol-generating article is removably coupled to an aerosol-generating device. The article may be disposable or reusable.

[0065] Aerosol-forming substrates may include solid aerosol-forming substrates.Solid aerosol-forming substrates may include tobacco-containing materials, and the tobacco-containing materials contain volatile tobacco flavor compounds released from the aerosol-forming substrate when heated.Solid aerosol-forming substrates may include non-tobacco materials.Solid aerosol-forming substrates may include tobacco-containing materials and do not contain tobacco materials.

[0066] 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., and spices can comprise menthol, European mint, 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.

[0067] 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 element 1 adapted to the aerosol generating device can convert electrical energy into other energy that is beneficial for the aerosol generating product 2 to generate aerosol.

[0068] In one embodiment, the energy is thermal energy. The electrical element 1 can generate heat and release heat when it is electrically conductive. At least part of the heat can heat the aerosol generating product 2, so that the aerosol generating product 2 generates aerosol. In one embodiment, the energy is infrared light energy. The electrical element 1 can generate infrared rays when it is electrically conductive. At least part of the infrared rays are emitted to the aerosol generating product 2 and absorbed by the aerosol generating product 2, so that the aerosol generating product 2 is heated up and an aerosol is generated. In one embodiment, the energy is microwave energy. The electrical element 1 can generate microwaves when it is electrically conductive. Microwaves can make the solvent or compound molecules in the aerosol generating product 2 vibrate at a high frequency, so that the aerosol generating product 2 is heated up and an aerosol is generated. In one embodiment, the energy is magnetic energy. The aerosol generating device or the aerosol generating product 2 may have a susceptor. The susceptor can generate eddy currents and / or hysteresis under the action of the magnetic energy, and then the susceptor can generate heat to heat the aerosol generating product 2, so that the aerosol generating product 2 generates an aerosol. It should be noted that the energy may also be other energy, such as ultrasound.

[0069] The electrical component 1 includes a first part 11 and a second part 12, and the first part 11 and the second part 12 can generate the above energy when the electricity is turned on. 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.

[0070] Since the first part 11 and the second part 12 are interconnected or integrally formed, energy can be transferred between the first part 11 and the second part 12 when either of them 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.

[0071] exist Figure 3 and Figure 5In the embodiment shown, the electrical element 1 is configured in a mesh shape, and the first part 11 and the second part 12 can be integrally formed of the same material, and there is a faster energy transfer speed, lower energy transfer loss and lower energy transfer barrier between the two. It should be noted that the electrical element 1 as a whole can be configured as a spiral coil, and the first part 11 and the second part 12 are components of the spiral coil, and the first part 11 and the second part 12 can be two coils formed by winding the same wire.

[0072] The aerosol generating device further includes a power supply component 3 and a delay circuit 4. The delay circuit 4 can be connected to the electrical element 1, and the power supply component 3 is used to provide power / electrical energy for the first part 11 and the second part 12 to generate energy. Only one of the first part 11 and the second part 12 may be associated with the delay circuit 4, while the other may not be associated with the delay circuit 4, so that whether one of the first part 11 and the second part 12 is in a working state or not, it does not affect the other being in a working state and providing energy for the aerosol generating product to generate aerosol. Specifically, the delay circuit 4 can make the first part 11 and the second part 12 either in a working state and provide energy at the same time, or only one of the two is in a working state and the other is in a non-working state, or one of the first part 11 and the second part 12 can provide energy before being in a working state.

[0073] The power supply assembly includes a power supply 31, and the power supply 31 may include any suitable power supply, 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 a lithium polymer battery. The power supply 31 may also include a first output pole 33 and a second output pole 34, the first part 11 and the second part 12 are connected between the first output pole 33 and the second output pole 34, and the power supply 31 provides power to the power-consuming element 1 through the first output pole 33 and the second output pole 34.

[0074] 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, electric power or frequency output by the power supply 31 to the electrical element 1; or, the control circuit may control the direction of the electric power output by the power supply 31 to the electrical element 1; or, the control circuit may directly control the delay circuit 4 to affect the working state of the first part 11 and the second part 12; or, the control circuit has no direct electrical connection with the delay circuit 4, or the control circuit cannot directly send a control signal 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 also control the operation of other components in the aerosol generating device. For example, the control circuit may determine whether the aerosol generating device can be operated by checking the state of the components of the aerosol generating device.

[0075] The control circuit may have a gate-controlled switch tube 6. In one example, the gate-controlled switch tube 6 is associated with a mechanical switch such as a key switch, a touch switch, a touch screen switch or a sliding switch, or the gate-controlled switch tube includes a mechanical switch. When the mechanical switch is triggered, or when the gate-controlled switch tube 6 is triggered, the control circuit uses the line between the electrical element 1 and the power supply 31 to be turned on, or the line between the electrical element 1 and the power supply 31 to be turned on. At this time, at least one of the first part 11 and the second part 12 can be in a working state and can provide energy, or one of the first part 11 and the second part 12 can generate energy before the other. In one example, the gate-controlled switch tube 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 tube 6 based on the switch drive signal, thereby using the line between the electrical element 1 and the power supply 31 to be turned on, so that at least one of the first part 11 and the second part 12 can be in a working state and can provide energy, or one of the first part 11 and the second part 12 can 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.

[0076] exist Figure 8-Figure 11In the illustrated embodiment, the gate-controlled switch tube 6 is disposed between the first output pole 33 and the power supply 31, or the gate-controlled switch tube 6 is disposed between the second output pole 34 and the electric eye 31. When the gate-controlled switch tube 6 is triggered or driven, the circuit between the electrical element 1 and the power supply 31 is conductive, that is, the circuit between the power supply 31 and the first output pole 33 and the second output pole 34 is conductive, so that the electrical element 1 can obtain the power generated by the energy from the first output pole 33 and the second output pole 34.

[0077] 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 line 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.

[0078] The delay circuit 4 may be arranged between the first part 11 and the gate-controlled switch tube 6 , or the delay circuit may be arranged between the second part 12 and the gate-controlled switch tube.

[0079] 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.

[0080] 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.

[0081] As an example of this embodiment, 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 unidirectional conduction switch is connected in series with only one of the first part 11 and the second part 12, so that the unidirectional conduction switch is associated with only one of the first part 11 and the second part 12. Therefore, when the unidirectional conduction switch is turned off, the part associated with the unidirectional conduction switch is in a non-working state because it is disconnected, and when the unidirectional conduction switch is turned on, the part associated with the unidirectional conduction switch is in a working state. The other part not associated with the unidirectional conduction switch may not be affected by the conduction or cutoff of the unidirectional conduction switch.

[0082] As an example of this embodiment, 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 unidirectional conduction switch is connected in parallel with only one of the first part 11 and the second part 12, so that the unidirectional conduction switch is associated with only one of the first part 11 and the second part 12. Therefore, when the unidirectional conduction switch is turned off, the part associated with the unidirectional conduction switch is in a working state, and when the unidirectional conduction switch is turned on, the part associated with the unidirectional conduction switch is in a non-working state because it is short-circuited. The other part that is not associated with the unidirectional conduction switch may not be affected by the conduction or cutoff of the unidirectional conduction switch.

[0083] 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 output power of 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.

[0084] Without influencing the state of the extension 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 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.

[0085] 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 open-circuited, and the other generates energy.

[0086] As an example, see Figure 8, the driving switch is a high-level driving switch Q. When the driving electrode of the driving switch Q has a high level, the driving 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 through the resistor R, and the anode terminal of the capacitor C is simultaneously connected to the driving electrode of the driving 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 element 1 and the power supply 31 is turned on, the output anode charges the capacitor C, so that the potential of the anode terminal of the capacitor C gradually increases until the level of the driving threshold is met, so that the driving switch Q is turned on. That is, in the process of the potential of the anode terminal of the capacitor C gradually increasing to the driving threshold, the driving switch is converted from cut-off to on.

[0087] Alternatively, you can refer to Fig. 9 , the driving switch Q is a low-level driving switch, and when the driving electrode of the driving switch Q has a low level, the driving 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 through the resistor R, and the anode terminal of the capacitor C is simultaneously connected to the driving electrode of the driving 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, so that when the line between the electrical element 1 and the power supply 31 is turned on, the output anode charges the capacitor C, so that the potential of the anode terminal of the capacitor C gradually increases until the level of the driving threshold is met, so that the driving switch Q is turned off. That is, in the process of the potential of the anode terminal of the capacitor C gradually increasing to the driving threshold, the driving switch Q is switched from on to off.

[0088] As an example, 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 driving switch is connected in series with only one of the first part 11 and the second part 12, so that the driving switch is associated with only one of the first part 11 and the second part 12. Therefore, when the driving switch is turned off, the part associated with the driving switch is in a non-working state because it is disconnected, and when the driving switch is turned on, the part associated with the driving switch is in a working state. The other part not associated with the driving switch may not be affected by the turning on or off of the driving switch.

[0089] As an example, 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 driving switch is connected in parallel with only one of the first part 11 and the second part 12, so that the driving switch is associated with only one of the first part 11 and the second part 12. Therefore, when the driving switch is turned off, the part associated with the driving switch is in a working state, and when the driving switch is turned on, the part associated with the driving switch is in a non-working state because it is short-circuited. The other part that is not associated with the driving switch may not be affected by the turning on or off of the driving switch.

[0090] In one embodiment, reference may be made to Fig.10 and Fig.11 The delay circuit includes a driving switch Q, a controller is directly electrically connected to the driving switch Q, and the controller is configured to drive the driving switch Q to be turned on or off, and the controller can directly send a control signal to the driving switch Q, and the driving switch Q is turned on or off in response to the control signal. When the driving switch is turned on, one of the first part 11 and the second part 12 is short-circuited or disconnected, and the other generates energy; or when the driving switch Q is turned off, one of the first part 11 and the second part 12 is short-circuited or disconnected, and the other generates energy.

[0091] As an example of this embodiment, the controller can control the driving 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.

[0092] Based on this, the aerosol generating device may further include a susceptor capable of generating heat energy in a changing magnetic field, and the susceptor is within the range of the changing magnetic field generated by the first part 11 and / or the second part 12. Alternatively, the aerosol raw food product includes a susceptor capable of generating heat energy in a changing magnetic field, and when the aerosol raw food product is combined with the aerosol generating device, the susceptor in the aerosol raw food product is within the range of the changing magnetic field generated by the first part 11 and / or the second part 12.

[0093] In one embodiment, the first portion 11 and the second portion 12 are integrally formed.

[0094] 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.

[0095] In one embodiment, the aerosol generating device also includes a accommodating cavity for accommodating at least a portion of the aerosol generating product, the first part 11 and the second part 12 are respectively arranged at different positions of the accommodating cavity, and along the direction of the airflow in the aerosol generating product, the first part 11 is arranged downstream of the second part 12.

[0096] As an example of this embodiment, the first part 11 generates energy before the second part 12.

[0097] 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 .

[0098] In one embodiment, in a first time period, the first part 11 generates energy, and in a second time period, both the first part 11 and the second part 12 generate energy. The first time period may be before the second time period, or may be after the second time period.

[0099] 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.

[0100] As an example of this embodiment, the first part 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 part 12. Alternatively, the first part 11 is configured such that the heating temperature in the second time period is less than or equal to the heating temperature of the second part 12 in the second time period.

[0101] 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.

[0102] The present application will be described in more detail below in conjunction with a more specific current schematic diagram.

[0103] 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.

[0104] 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, and 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.

[0105] Please refer to Figure 2-Figure 7 The aerosol generating device includes a first circuit 35, a second circuit 36 ​​and a third circuit 37. The first circuit 35 and the third circuit 37 are both connected to the second circuit 36. The first part 11 is arranged on the first circuit 35, and the second part 12 is arranged on the third circuit 37. Figure 3 As shown, the first line 35 and the third line 37 are connected in parallel between the first output pole 33 and the second output pole 34 of the power supply component 3; or Figure 5 As shown, the first line 35 and the third line 37 are connected in series between the first output pole 33 and the second output pole 34 of the power supply assembly 3 .

[0106] 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.

[0107] When the delay circuit 4 is only associated with the third line 37, and the power supply 31 is outputting power through the first output pole 33 and the second output pole 34, if the delay circuit 4 makes the third line 37 electrically conductive, the second part 12 can draw power from the first output pole 33 and the second output pole 34 and enter the working state. At the same time, when the third line 37 is electrically conductive, the first part 11 that is not associated with the delay circuit 4 can also draw power from the first output pole 33 and the second output pole 34 and be in the working state; if the delay circuit 4 makes the third line 37 short-circuited or open-circuited, the first part 11 can be unaffected by the delay circuit 4 and can still draw power from the first output pole 33 and the second output pole 34 and be in the working state, but the third line 37 is short-circuited or open-circuited, so that the second part 12 is in the non-working state. Therefore, the number of hardware components in the aerosol generating device is small, and the connection and arrangement between them are simple, which helps to reduce costs and reduce energy consumption in the circuit.

[0108] In one embodiment, see Figure 2 , Figure 3 and Figure 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 part of the delay circuit 4, so that at least a part of the delay circuit 4 is connected in series with the third line 37 / the second part 12. Therefore, when the delay circuit 4 is in the on-associated line state, the third line 37 is turned on, and the second part 12 is in the working state. When the delay circuit 4 is in the off-associated line state, the third line 37 is disconnected, and the second part 12 is in the non-working state.

[0109] 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.

[0110] In one embodiment, see Figure 4 , Figure 5 and Figure 7The 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 part of the delay circuit 4, so that at least a part of the delay circuit 4 is connected in parallel with the third line 37 / the second part 12. Therefore, when the delay circuit 4 is in the on-associated line state, the third line 37 is short-circuited, and the second part 12 is in a non-working state. When the delay circuit 4 is in the off-associated line state, the third line 37 is turned on, and the second part 12 is in a working state.

[0111] 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.

[0112] Based on the first aspect of the present application, at least part of the delay circuit 4 is in series with the second part 12. When the delay circuit 4 is in the state of conducting the associated line, the second part 12 is turned on and in the working state. When the delay circuit 4 is in the state of cutting off the associated line, the line where the second part 12 is located is disconnected, so that the second part 12 is in the non-working state. For example, the delay circuit 4 includes a unidirectional conduction switch, and the power supply component 3 is configured to switch the direction in which the first output pole 33 and the second output pole 34 output power. Therefore, the unidirectional conduction switch can be controlled to be turned on or off by switching the direction in which the first output pole 33 and the second output pole 34 output power, so that the second part 12 is in the working state or in the non-working state.

[0113] Based on the second aspect of the present application, at least part of the delay circuit 4 is in parallel with the second part 12. When the delay circuit 4 is in the state of conducting the associated line, the line where the second part 12 is located is short-circuited, so that the second part 12 is in a non-working state. When the delay circuit 4 is in the state of cutting off the associated line, the line where the second part 12 is located is turned on and the second part 12 is in a working state. For example, the delay circuit 4 includes a unidirectional conduction switch, and the power supply component 3 is configured to switch the direction in which the first output pole 33 and the second output pole 34 output power. Therefore, the unidirectional conduction switch can be controlled to be turned on or off by switching the direction in which the first output pole 33 and the second output pole 34 output power, so that the second part 12 is in a working state or a non-working state.

[0114] Among them, the unidirectional conduction switch is a switch that only allows the circuit in which it is located to be unidirectionally conducted. For example: when the potential of the first output pole 33 is higher than the potential of the second output pole 34, the direction in which the first output pole 33 and the second output pole 34 output power is in the first direction, and the unidirectional conductive element is turned on; when the potential of the first output pole 33 is lower than the potential of the second output pole 34, the direction in which the first output pole 33 and the second output pole 34 output power is in the second direction different from the first direction, and the unidirectional conductive element is turned off.

[0115] The unidirectional conductive element includes, but is not limited to, a diode.

[0116] 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 a conductive associated line state or in a cutoff 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 transistors are divided into PMOS transistors and NMOS transistors), a thyristor (silicon controlled rectifier) ​​and an IGBT [IGBT (Insulated Gate Bipolar Transistor), an 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.

[0117] Thus, when the delay circuit 4 is in the state of conducting the associated line, the second part 12 is turned on and in the working state, and when the delay circuit 4 is turned off, the line where the second part 12 is located is disconnected, so that the second part is in the non-working state. And the control component 32 can be used to drive the delay circuit 4 to be in the state of conducting the associated line or in the state of cutting off the associated line, so that the second part 12 is in the working state or in the non-working state. Based on the third aspect, the delay circuit 4 is in the state of conducting the associated line or in the state of cutting off the associated line not because the direction of the output power of the first output pole 33 and the second output pole 34 changes.

[0118] 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 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 a state of turning on the associated line or in a state of turning off the associated line. At this time, the delay circuit 4 or the driving switch may include a transistor.

[0119] Thus, when the delay circuit 4 is in the state of conducting the associated line, the line where the second part 12 is located is short-circuited, so that the second part is in a non-working state. When the delay circuit 4 is in the state of cutting off the associated line, the line where the second part 12 is located is turned on and the second part 12 is in a working state. And the control component 32 can be used to drive the delay circuit 4 to be in the state of conducting the associated line or in the state of cutting off the associated line, so that the second part 12 is in a working state or in a non-working state. Based on the fourth aspect, the delay circuit 4 is in the state of conducting the associated line or in the state of cutting off the associated line not because the direction of the output power of the first output pole 33 and the second output pole 34 changes.

[0120] Based on the fifth aspect of the present application, at least part of the delay circuit 4 is in series or parallel with the second part 12, and the driving switch in the delay circuit 4 has a conduction voltage. When the voltage across the driving switch is greater than the conduction voltage, the delay circuit 4 is in a conduction associated line state, and when the voltage across the driving switch is less than the conduction voltage, the delay circuit 4 is in a cutoff associated line state. The control circuit on the control component 32 can control the voltage across the driving switch, thereby controlling the delay circuit 4 to be turned on or off. Or the delay circuit 4 can control the voltage across the driving switch by itself.

[0121] Based on the sixth aspect of the present application, at least a portion 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 electrode. The delay circuit 4 can automatically make the voltage or current on the driving electrode reach a threshold value for driving the driving electrode, thereby making the delay circuit 4 in a state of conducting the associated line or in a state of cutting off the associated line.

[0122] 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.

[0123] As an example, at least one of the first portion 11 and the second portion 12 includes a resistive heating element.

[0124] The resistive heating element includes a resistive material that can generate 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.

[0125] The resistive heating elements include MESH nets, resistive coils, resistive heating tracks or resistive coatings, etc.

[0126] 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 prepared 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 prepared 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. The infrared electric heating coating can also be a coating of other existing materials.

[0127] As an example, the first line 35 where the first part 11 is located is configured to remain on when the power supply component 3 outputs power through the first output pole 33 and the second output pole 34, so that the first part 11 can continue to generate heat energy when the power supply component 3 outputs power through the first output pole 33 and the second output pole 34. The delay circuit 4 can be in a state of being in an on-associated line state or in a state of being in an off-associated line state, so that when the power supply component 3 outputs power through the first output pole 33 and the second output pole 34, the second part 12 can generate heat energy only in a part of the time period, or can generate heat energy all the time, or can not generate heat energy all the time.

[0128] 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.

[0129] The second part 12 can be configured to be electrically conductive and in working state in the second time period, so that the second part 12 can be in non-working state in the first time period, and can be in working state in the second time period to generate heat. The second time period can be after the first time period, so the first part 11 can generate heat energy before the second part.

[0130] In one embodiment, an insertion port for inserting the aerosol generating product into the accommodating cavity is provided at the upper end of the aerosol generating device. With reference to the insertion port being located at the upper end of the aerosol generating device, the first part 11 is provided above the second part 12, and relative to the second part 12, the distance between the first part 11 and the insertion port is smaller than the distance between the second part 12 and the insertion port. The heat energy generated by the first part 11 and the second part 12 is respectively used to heat different parts of the aerosol generating product 2. In order to shorten the time for the user to wait for the first aerosol generated by the aerosol generating product to be inhaled, the first part 11 provided above the second part 12 can be put into the working state and generate heat energy first, and then the first part 11 and the second part can be simultaneously in the working state and generate heat energy at the same time.

[0131] As an example, 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. Therefore, the temperature of the first part 11 in the first time period or the amount of heat released per unit time in the first time period may be greater than the temperature of the first part 11 in the second time period or the amount of heat released per unit time in the second time period; or, in the first time period and the second time period, the first part 11 may have approximately the same heating temperature or be able to release approximately the same amount of heat per unit time.

[0132] Specifically, in Figure 3 In the illustrated embodiment, 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 the first part 11 by the first output pole 33 and the second output pole 34 in the first time period may be greater than or equal to the voltage applied 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 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 may be greater than or equal to 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 second time period.

[0133] In such Figure 5 In the illustrated embodiment, 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 may 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 may 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.

[0134] 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.

[0135] As an example, the first part 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 part 12. Thus, in the second time period, the temperature of the first part 11 or the amount of heat released per unit time is less than or equal to the temperature of the second part 12 or the amount of heat released per unit time.

[0136] For example, you can Figure 3As shown, 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, so that the first part 11 is shunted by the second part 12 in the second time period, thereby causing the current flowing through the first part 11 to decrease and the electric power to decrease.

[0137] For example, you can Figure 3 As shown, 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 across 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.

[0138] For example, you can Figure 5 As shown, 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 the voltage across the first part 11 and a decrease in the electric power.

[0139] For example, you can Figure 5 As shown, 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.

[0140] 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 the user to inhale, the first time period may be ended, and the remaining time for heating the aerosol generating article may be the second time period, but is not limited thereto.

[0141] 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.

[0142] 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.

[0143] As an example, the first part 11 and the second part 12 are arranged around the containing cavity, so that when at least a portion of the aerosol generating article 2 is combined in the containing 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.

[0144] As an example, the first part 11 and the second part 12 are arranged in a containing cavity, and when the aerosol generating article 2 is at least partially combined with the containing 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.

[0145] 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.

[0146] That is, based on the sensing result of the temperature sensor 5, in the first time period, 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 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.

[0147] Alternatively, based on the sensing result of the temperature sensor 5, in the first time period and the second time period, 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 be approximately equal to ensure the consistency of each puff of aerosol generated by the aerosol generating article 2.

[0148] Alternatively, based on the sensing result 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.

[0149] Alternatively, based on the sensing result 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, so as to ensure the stability, continuity and consistency of the aerosol generated by the aerosol generating product 2 in each mouthful, and prevent the aerosol generating product 2 from being burnt or burned.

[0150] When the first part 11 is disposed above the second part 12, and the first part 11 generates heat energy in both the first time period and the second time period, the second part 12 generates heat energy in the second time period, and the second time period is after the first time period, the temperature sensor 5 can be combined with the first part 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 part 11.

[0151] 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.

[0152] It should be noted that the control component 32 can also control the power output direction of the first output pole 33 and the second output pole 34, or control the control state of the delay circuit 4, to end the first time period and enter the second time period based on other judgment criteria, such as whether the duration of the first time period reaches a preset duration, etc. Among them, the second time period can be entered immediately after the first time period ends.

[0153] Based on the third aspect or the fourth aspect of the present application, at least one of the first part 11 and the second part 12 can be configured to generate magnetic energy. The power supply component 3 is configured to provide alternating current to the first part 11 and the second part 12, and the alternating current includes alternating current or alternating voltage, so that the first part 11 and the second part 12 can generate a changing magnetic field.

[0154] In one example, the first part 11 and / or the second part 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 part 11 and / or the second part 12 can generate a variable magnetic field with a field strength (H field) between 1 and 5 kA / m, for example, between 2 and 3 kA / m, for example, about 2.5 kA / m. Figure 6 , the first portion 11 and / or the second portion 12 may both be configured as a spiral coil.

[0155] In one example, the aerosol generating device may further include a susceptor capable of generating heat in a changing magnetic field, and the susceptor may be arranged around the accommodating cavity so that the susceptor can heat the aerosol generating product 2 from the outside of the aerosol generating product 2, or at least a portion of the susceptor may be arranged in the accommodating cavity so that the susceptor can heat the aerosol generating product 2 from the inside of the aerosol generating product 2. The susceptor may include metal or carbon. Carbon includes graphite, graphite alloy, graphene, etc. In one example, the susceptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In one example, the susceptor includes a nickel-iron alloy. In one embodiment, the susceptor includes 400 series stainless steel, and the 400 series stainless steel includes 410 grade, 420 grade, or 430 grade stainless steel.

[0156] In one example, a susceptor is disposed inside the aerosol-generating article 2 .

[0157] Wherein, no matter the receptor is incorporated into the aerosol generating device or the aerosol generating product 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 part of the receptor can be set in the changing magnetic field range generated by the first part 11, and a part can be set in 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.

[0158] 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 portions of the aerosol-generating article 2 .

[0159] As an example, see Figure 6 and Figure 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.

[0160] The second part 12 can be configured to be electrically conductive and in working state in a second time period, and the sensor corresponding to the second part 12 can generate heat in the second time period, and the second time period can be after the first time period.

[0161] 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 .

[0162] As an example, the aerosol generating device further includes a temperature sensor 5 , which is coupled to the receptor and 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 power-consuming element 1 based on the sensing result of the temperature sensor 5 .

[0163] 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.

[0164] For example, when the temperature sensor 5 detects that the temperature on the sensing body corresponding to the first part 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 sensing body corresponding to the first part 11 maintains a preset temperature for a preset time period, the control component can control the drive switch Q to be turned on or off, thereby controlling to end the first time period and enter the second time period.

[0165] 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.

[0166] In one embodiment, the aerosol generating device includes a flexible circuit board, at least one of the first circuit, the second circuit and the third circuit is arranged on the flexible circuit board, and the delay circuit is arranged on the flexible circuit board. More specifically, the flexible circuit board is connected to the control component, so that the delay circuit can exist independently of the control component. More specifically, the first output pole and the second output pole can be arranged on the control component, that is, the first output pole and the second output pole can exist independently of the flexible circuit board. In other embodiments, the control component is part of the flexible circuit board, and the control component can be flexible.

[0167] In one embodiment, the first output pole, the second output pole and the delay circuit are all arranged on the control component.

[0168] 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.

[0169] The first part 11 and the second part 12 may be connected to each other, and a connecting section connecting the first part 11 and the second part 12 may be made of the same material as the first part 11 and / or the second part 12, and the connecting section may be a band-like structure extending along the circumference of the accommodating cavity.

[0170] After the first part 11 and the second part 12 are connected to each other, there may be no obvious boundary between the first part 11 and the second part 12. Of course, the possibility of having a clear boundary is not excluded.

[0171] The first part 11 and the second part 12 may both be components of the electrical component 1, and the first part 11 and the second part 12 may respectively constitute parts of the electrical component 1. Figure 2 and Figure 4 In the illustrated embodiment, the electrical component 1 is roughly a mesh when laid flat, and the mesh-like first portion 11 and the mesh-like second portion 22 each occupy a portion of the mesh.

[0172] The first portion 11 and the second portion 12 may be integrally formed.

[0173] When power is obtained, the first part 11 and the second part 12 can provide heat for the aerosol generating article 2 to generate aerosol. In the seventh aspect of the present application, only one of the first part 11 and the second part 12 is connected in series or in parallel with the delay circuit 4. Thus, when the power supply component 3 provides power to the first part 11 and the second part 12 at the same time, the first part 11 and the second part 12 do not generate heat at the same time in a preset time period. It should be noted that when the power supply component 3 provides power to the first part 11 and the second part 12 at the same time, because of the existence of the delay circuit 4, the first part 11 and the second part 12 cannot obtain power at the same time in the preset time period, so that the first part 11 and the second part 12 do not generate heat at the same time in the preset time period.

[0174] A controller and a gated switch tube 6 can be provided in the aerosol generating device. The controller can drive the gated switch tube 6 to be turned on or off based on a switch driving signal. When the gated 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 turned on, so that the power supply component 3 can provide power to the first part 11 and the second part 12 at the same time, and when the line between the electrical element 1 and the power supply 31 in the power supply component 3 is turned on, at least one of the first part 11 and the second part 12 can generate heat.

[0175] According to an embodiment of the seventh aspect of the present application, in a first time period, the first part 11 and the second part 12 generate heat simultaneously, and in a second time period, only the first part 11 generates heat. The first time period is before the second time period.

[0176] 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 suspends or stops generating heat.

[0177] For example, in the first time period, after the first part 11 and the second part 12 generate heat simultaneously for a period of time, a large amount of heat is accumulated in the aerosol generating article 2. If the first part 11 and the second part 12 continue to generate a large amount of heat simultaneously, it may cause at least partial overheating of the aerosol generating article 2 or problems such as scorching or burning. At this time, the first time period can be ended and the second time period can be entered, and only the first part 11 of the first part 11 and the second part 12 is allowed to generate heat, while the second part is suspended or stopped from generating heat, so that part of the heat accumulated in the aerosol generating article 2 can be released. Compared with directly stopping the first part 11 and the second part 12 from generating heat simultaneously, only the first part 11 is allowed to generate heat, which can ensure that the aerosol generating article 2 can generate aerosol with a uniform taste in the first time period and the second time period, and will not cause a significant reduction in the amount of aerosol generated, which helps to ensure the consistency of each puff.

[0178] If the aerosol generating article 2 is not completely heated at the end of the second time period, the first part 11 and the second part 12 may be simultaneously heated again in a third time period after the second time period, and then only the first part 11 of the first part 11 and the second part 12 may be heated in a fourth time period after the third time period. This process is repeated by analogy until the aerosol generating article 2 is completely heated.

[0179] The total resistance per unit area of ​​the first part 11 can be set to be smaller than the total resistance per unit area of ​​the second part 12, or the heat generated per unit area of ​​the first part 11 can be set to be smaller than the heat generated per unit area of ​​the second part 12. For example, the mesh of the first part 11 can be larger than the mesh of the second part 12. That is, the hole area of ​​the mesh in the first part 11 can be larger than the hole area of ​​the mesh in the second part 12, or the width of the wall defining the mesh in the first part 11 can be larger than the width of the wall defining the mesh in the second part 12, or the cross-sectional area of ​​the wall defining the mesh in the first part 11 for current to pass through can be larger than the cross-sectional area of ​​the wall defining the mesh in the second part 12 for current to pass through.

[0180] Based on this, as an example, the first part 11 and the second part 12 are respectively arranged at different positions of the accommodating cavity, and along the direction of the airflow in the aerosol generating article 2, the first part 11 can be arranged downstream of the second part 12. In other words, in the first time period, the first part 11 and the second part 12 generate heat at the same time, and in the first time period, the heat generated per unit time or per unit area by the first part 11 can be less than the heat generated per unit time or per unit area by the second part 12; in the second time period, the first part 11 located downstream continues to generate heat, and the second part 12 does not generate heat in the second time period.

[0181] In another embodiment of the seventh aspect of the present application, in the first time period, only the first part 11 generates heat between the first part 11 and the second part 12, and in the second time period, the first part 11 and the second part 12 generate heat simultaneously. The first time period is before the second time period.

[0182] 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.

[0183] For example, in the first time period, after only the first part 11 of the first part 11 and the second part 12 generates heat for a period of time, so that the corresponding area of ​​the aerosol generating article 2 is fully preheated, or the aerosol generating article 2 quickly generates the first aerosol for the user to inhale, if only the first part 11 of the first part 11 and the second part 12 continues to generate heat, while the second part 12 continues to not generate heat, it may affect the 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. At this time, the first time period can be ended and the second time period can be entered, so that the first part 11 and the second part 12 generate heat at the same time, so that the aerosol generating article 2 is heated more evenly and comprehensively, and the aerosol generating article 2 can generate aerosol in a larger range. Compared with allowing only 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, preventing the airflow in the corresponding area from being too low in temperature, and helping to fully heat the corresponding area.

[0184] If the aerosol generating article 2 is not completely heated at the end of the second time period, only the first part 11 of the first part 11 and the second part 12 may be heated in a third time period after the second time period, and then the first part 11 and the second part 12 may be heated simultaneously again in a fourth time period after the third time period. This process is repeated by analogy until the aerosol generating article 2 is completely heated.

[0185] The total resistance per unit area of ​​the first part 11 can be greater than or equal to the total resistance per unit area of ​​the second part 12 , or the heat generated per unit area of ​​the first part 11 can be greater than or equal to the heat generated per unit area of ​​the second part 12 .

[0186] For example, the mesh size of the first part 11 can be equal to that of the mesh size of the second part 12, or the mesh wall of the first part 11 can be smaller than the mesh size of the second part 12. That is, the hole area of ​​the mesh in the first part 11 can be smaller than or equal to the hole area of ​​the mesh in the second part 12, or the width of the wall defining the mesh in the first part 11 can be smaller than or equal to the width of the wall defining the mesh in the second part 12, or the cross-sectional area of ​​the wall defining the mesh in the first part 11 for current to pass through can be smaller than or equal to the cross-sectional area of ​​the wall defining the mesh in the second part 12 for current to pass through.

[0187] Based on this, as an example, the first part 11 and the second part 12 are respectively arranged at different positions corresponding to the accommodating cavity, and along the direction of the airflow in the aerosol generating article 2, the first part 11 can be arranged downstream of the second part 12. In other words, in the first time period, only the first part 11 of the first part 11 and the second part 12 generates heat, and under the heat generated by the first part 11, the corresponding area of ​​the aerosol generating article 2 is preheated, or the corresponding area can quickly generate the first aerosol; in the second time period, the second part located upstream generates heat, and the first part 11 located downstream continues to generate heat, and in the second time period, the heat generated per unit time or per unit area by the first part 11 can be more than or equal to the heat generated per unit time or per unit area by the second part 12. Of course, the power provided by the power supply component 3 can be adjusted so that in the second time period, the heat generated per unit time or per unit area by the first part 11 is less than or equal to the heat generated per unit time or per unit area by the second part 12.

[0188] In the above-mentioned aerosol generating device, when the gate-controlled switch tube uses the line 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 to control one of the first part and the second part to generate energy before the other after the controller generates a control signal to control the line between the electrical element and the power supply to be turned on, not only is the control method and hardware structure simpler, but also the required energy consumption is lower, which can effectively reduce the production and use costs.

[0189] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill 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 the present application.
