[0041] The realization of the purpose of this application, its functional features and advantages will be further described in conjunction with embodiments with reference to the accompanying drawings. Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0043] As Figure 1 shown, in order to solve the problem that the air regulating mechanism on the existing aerosol generating device cannot achieve precise air regulation, this application proposes an aerosol generating device 100, which mainly includes a body 10 and an air regulating assembly 20.

[0044] Among them, as Figure 1 shown, an air flow channel 11 is provided in the body 10, and the air flow channel 11 has an air inlet 111. Specifically, in this embodiment, the body 10 is composed of a housing 14, a gas guiding assembly, an atomizing assembly, a liquid supply assembly and a power supply assembly. The housing 14 provides an installation space and protection for other components, and a mouthpiece 141 is provided on the housing 14. The gas guiding assembly mainly includes a gas guiding pipe 15. The gas guiding pipe 15 is installed in the housing 14, and a part of the air flow channel 11 is formed inside the gas guiding pipe 15. The other parts of the air flow channel 11 can be formed by the gaps between the components. The specific forming method can be realized according to relevant existing technologies.

[0045] The air flow channel 11 forms an air inlet 111 at the lower end of the body 10 and an air outlet 115 at the mouthpiece 141. When the user sucks, the air outside the body 10 flows into the air flow channel 11 from the air inlet 111, then flows along the air flow channel 11 to the air outlet 115, and finally flows out from the air outlet 115 and into the user's mouth.

[0046] The atomizing assembly is installed in the air flow channel 11, and it can include a heating element 13, a liquid absorbing cotton, electric wires, etc. The heating element 13 is electrically connected to the power supply assembly through the electric wires, so that the heating element 13 can be powered on and heated. The liquid absorbing cotton is usually sleeved outside the heating element 13, and the liquid absorbing cotton is used to absorb the atomizing liquid from the liquid supply assembly and guide the atomizing liquid to the heating element 13, so that the heated heating element 13 can atomize the atomizing liquid.

[0047] As described above, the liquid supply assembly is mainly used to provide atomizing liquid for the atomizing assembly. It may include a liquid cup 16, which is provided with a liquid storage cavity inside. The atomizing liquid is stored in the liquid storage cavity, and a liquid outlet may be provided on the side wall of the liquid storage cavity corresponding to the position of the absorbent cotton, so that the absorbent cotton in the atomizing assembly can adsorb the atomizing liquid to the heating element.

[0048] The power supply assembly generally includes a battery 17, a control board, etc. The control board is electrically connected to the battery 17, and the atomizing assembly is electrically connected to the control board through an electric wire, so that the operation or non-operation of the atomizing assembly can be controlled through the control board.

[0049] In summary, the body 10 in the present application can realize the basic functions of the aerosol generating device 100. Without adding other components, the user can directly suck on the body 10. When sucking, the air outside the body 10 flows into the air flow channel 11 from the air inlet 111 at the lower end of the body 10. At the same time, the atomizing assembly atomizes the atomizing liquid into aerosol. The air flows along the air flow channel 11 to the atomizing assembly and mixes with the aerosol, and then continues to flow along the air flow channel 11 to the air outlet 115, and finally flows out from the air outlet 115 and into the user's mouth.

[0050] Crucially, in the present application, as Figure 1 shown, the aerosol generating device 100 further includes an air regulating assembly 20. The air regulating assembly 20 is movably installed at the air inlet 111, and a plurality of ventilation holes 21 are provided on the air regulating assembly 20. The sizes of the plurality of ventilation holes 21 are different from each other. The air regulating assembly 20 can move relative to the body 10 to make one of the ventilation holes 21 communicate with the air inlet 111. When the ventilation hole 21 communicates with the air inlet 111, the air flow channel 11 communicates with the outside of the body 10 through the ventilation hole 21 and the air inlet 111.

[0051] Specifically, the specific composition of the air regulating assembly 20 can be flexibly set according to the actual situation. For example, when the air outlet 115 is located at the lower end of the circumferential side surface of the body 10, the air regulating assembly 20 may include an air regulating ring, which is rotatably sleeved on the circumferential side surface of the body 10, and a plurality of ventilation holes 21 are penetrated through the air regulating ring. The air regulating ring rotates to make any one of the ventilation holes 21 communicate with the air inlet 111 correspondingly.

[0052] For another example, when the air outlet 115 is located on the lower end surface of the body 10, the air regulating assembly 20 may include an air regulating turntable, which is rotatably installed on the lower end surface of the body 10, and a plurality of ventilation holes 21 are penetrated through the air regulating turntable. The air regulating turntable rotates to make any one of the ventilation holes 21 communicate with the air inlet 111 correspondingly.

[0053] For still another example, as Figure 2 or Figure 4As shown, when the air outlet 115 is located on the lower end face of the body 10, the air regulating component 20 may include a sliding block 23. The sliding block 23 is slidably mounted on the lower end face of the body 10, and a plurality of ventilation holes 21 (including a first ventilation hole 211 and a second ventilation hole 212) penetrate through the sliding block 23. The sliding block 23 makes any one of the ventilation holes 21 communicate with the air inlet 111 in a sliding manner.

[0054] After the ventilation hole 21 communicates with the air inlet 111, the air flow channel 11 in the body 10 is communicated with the outside of the body 10 through the air inlet 111 and the ventilation port, so that the outside air of the body 10 can flow into the air flow channel 11 through the air inlet 111 and the ventilation hole 21.

[0055] In this embodiment, because the sizes of the plurality of ventilation holes 21 are set differently, when different ventilation holes 21 communicate with the air inlet 111 correspondingly, the air intake at the air inlet 111 will also be different. Therefore, when the air regulating component 20 is driven to move relative to the body 10 to make different ventilation holes 21 communicate with the air inlet 111, the air regulating function is realized.

[0056] Here, it should be noted that in order to ensure that the air regulating function (i.e., the adjustment of the air intake) can be realized when different ventilation holes 21 communicate with the air inlet 111 correspondingly, the air inlet 111 needs to be larger than all the ventilation holes 21, or the air inlet 111 needs to be larger than or equal to the largest ventilation hole 21. The so-called "the ventilation hole 21 communicates with the air inlet 111" means that the projection of the ventilation hole 21 on the air inlet 111 is completely located within the air inlet 111, that is, the ventilation hole 21 is completely communicated with the air inlet 111, and at this time, the air intake is determined by the size of the ventilation hole 21.

[0057] In addition, it should be noted that the size of the ventilation hole 21 is fixed. When the air regulating component 20 moves relative to the body 10, the size of the ventilation hole 21 itself will not change. Therefore, when the aerosol generating device 100 is configured to have multiple usage modes and each mode requires an accurate air intake to achieve the best experience effect, multiple ventilation holes 21 can correspond to realize one usage mode.

[0058] Specifically, during production, the specific size (i.e., the opening area) of each ventilation hole 21 can be determined through calculation, testing, etc., so that the air intake of each ventilation hole 21 corresponds to one usage mode of the aerosol generating device 100.

[0059] When air adjustment is needed, the user can drive the air adjustment component 20 to move relative to the body 10, so that one of the ventilation holes 21 is correspondingly communicated with the air inlet 111 of the air flow channel 11. Since the size of each ventilation hole 21 corresponds to a certain use mode of the aerosol generating device 100 during production and remains unchanged during the air adjustment process, the user can accurately adjust the air intake required for a certain use mode, achieving accurate air adjustment and ensuring that the user can experience the best experience effect in a certain use mode of the aerosol generating device 100.

[0060] For example, optionally, in one embodiment, the aerosol generating device 100 is configured to have a first use mode and a second use mode. The plurality of ventilation holes 21 include a first ventilation hole 211 and a second ventilation hole 212, and the first ventilation hole 211 is larger than the second ventilation hole 212; the first ventilation hole 211 is used to communicate with the air inlet 111 in the first use mode, and the second ventilation hole 212 is used to communicate with the air inlet 111 in the second use mode.

[0061] Specifically, in this embodiment, the first use mode is the lung inhalation mode, and the second use mode is the mouth inhalation mode. The lung inhalation mode means that after the user inhales the aerosol, the aerosol enters the lungs, and the mouth inhalation mode means that after the user inhales the aerosol, the aerosol stays in the mouth. The ventilation volume required for the lung inhalation mode is greater than the ventilation volume required for the mouth inhalation mode.

[0062] In this embodiment, the size of the first ventilation hole 211 is set corresponding to the lung inhalation mode, and the size of the second ventilation hole 212 is set corresponding to the mouth inhalation mode. Moreover, the first ventilation hole 211 is larger than the second ventilation hole 212. The first ventilation hole 211 is used to communicate with the air inlet 111 in the lung inhalation mode (i.e., the first use mode), and the second ventilation hole 212 is used to communicate with the air inlet 111 in the mouth inhalation mode (i.e., the second use mode). In this way, the user can accurately adjust the air intake required for the lung inhalation mode or the mouth inhalation mode, and then experience the best lung inhalation effect or mouth inhalation effect.

[0063] It should be noted here that based on different types of aerosol generating devices 100, the size of the air flow channel 11 in the body 10 will also be different, and the sizes of the corresponding first ventilation hole 211 and second ventilation hole 212 will also be different. In actual application, the sizes of the first ventilation hole 211 and the second ventilation hole 212 can be determined by means such as calculation, simulation, and testing, so that the ventilation volume of the first ventilation hole 211 is accurately corresponding to the ventilation volume required to achieve the best effect in the lung inhalation mode, and the ventilation volume of the second ventilation hole 212 is accurately corresponding to the ventilation volume required to achieve the best effect in the mouth inhalation mode.

[0064] In addition, the air regulating assembly 20 can make the first ventilation hole 211 or the second ventilation hole 212 communicate with the air inlet 111 correspondingly by means of rotation, sliding, etc. For example, optionally, in one embodiment, as Figure 4 shown, the air regulating assembly 20 is slidably mounted on the body 10, and the first ventilation hole 211 and the second ventilation hole 212 are arranged at intervals along the sliding direction of the air regulating assembly 20. Specifically, since the body 10 and the air inlet 111 are fixed, and the first ventilation hole 211 and the second ventilation hole 212 are arranged at intervals along the sliding direction of the air regulating assembly 20, when the air regulating assembly 20 slides relative to the body 10, the first ventilation hole 211 and the second ventilation hole 212 can move to the position communicating with the air inlet 111. It can be understood that when the air regulating assembly 20 makes the first ventilation hole 211 or the second ventilation hole 212 communicate with the air inlet 111 correspondingly by sliding, not only the structure is relatively simple, easy to disassemble and assemble, but also it is convenient for the user to operate and improves the use experience.

[0065] Optionally, in one embodiment, as Figures 5 to 10 shown, the air regulating assembly 20 is configured to be able to linearly slide relative to the body 10 between a first position and a second position;

[0066] Wherein, as Figure 5 and Figure 6 shown, when the air regulating assembly 20 is in the first position, the first ventilation hole 211 is completely communicated with the air inlet 111, and the second ventilation hole 212 is arranged in a staggered manner with the air inlet 111 (i.e., completely not communicated). At this time, the user can experience the best lung inhalation effect.

[0067] As Figure 7 and Figure 8 shown, when the air regulating assembly 20 is in the second position, the second ventilation hole 212 is completely communicated with the air inlet 111, and the first ventilation hole 211 is arranged in a staggered manner with the air inlet 111 (i.e., completely not communicated). At this time, the user can experience the best mouth inhalation effect.

[0068] As Figure 9 and Figure 10 shown, when the air regulating assembly 20 is between the first position and the second position, a part of the first ventilation hole 211 and / or the second ventilation hole 212 is communicated with the air inlet 111. Specifically, in Figure 10In the state shown, the air regulating component 20 is located between the first position and the second position, and the air regulating component 20 is closer to the first position. At this time, a part of the first ventilation hole 211 is communicated with the air inlet 111, and a part of the first ventilation hole is not communicated with the air inlet 111, and the second ventilation hole 212 is completely not communicated with the air inlet 111. Therefore, at this time, the ventilation area of the second ventilation hole 212 is smaller than the ventilation area when the air regulating component 20 is located at the first position, and the ventilation volume of the air inlet hole is smaller than the ventilation volume when the air regulating component 20 is located at the first position. And when the air regulating component 20 moves slowly towards the second position (i.e., Figure 8 the position shown), the ventilation area of the second ventilation hole 212 decreases, and the ventilation volume of the air inlet hole also gradually decreases.

[0069] It can be understood that when the air regulating component 20 gradually approaches the second position but has not reached the second position, the ventilation area of the first ventilation hole 211 gradually decreases, and a part of the second ventilation hole 212 also begins to be communicated with the air inlet 111, that is, the ventilation area of the second ventilation hole 212 gradually increases.

[0070] That is to say, when the air regulating component 20 moves between the first position and the second position, the ventilation volume of the air inlet 111 also gradually increases or decreases, so that stepless adjustment of the air intake volume is achieved.

[0071] Therefore, on the basis of realizing precise adjustment of the air flow rate, the present application can also realize stepless adjustment of the air flow rate, and the air regulating function is more comprehensive.

[0072] It should be noted here that in order to enable the air regulating component 20 to be more accurately positioned at the first position and the second position, a positioning structure can be provided on the body 10, such as a positioning baffle, a positioning stop post, etc. When the air regulating component 20 abuts against the positioning structure, it can be judged that the air regulating component 20 has reached the first position or the second position.

[0073] Alternatively, optionally, in another embodiment, please refer to Figure 3 、 Figure 5 and Figure 7 , the aerosol generating device 100 further includes a cover body 30, and the cover body 30 is fixedly connected to the body 10. Specifically, the cover body 30 covers the lower end of the body 10, and the cover body 30 can be fixed to the body 10 by means of snap connection, screw connection, bonding, integral molding, etc. And in this embodiment, a positioning through hole 31 is provided on the cover body 30, and the positioning through hole 31 has a first positioning end 311 and a second positioning end 312 opposite to each other along the sliding direction of the air regulating component 20.

[0074] Such as Figure 6 or Figure 8As shown, the air regulating component 20 is slidably installed between the body 10 and the cover 30, and the air regulating component 20 is provided with a knob 22 which passes through the positioning through hole 31. As Figure 5 shown, when the air regulating component 20 is in the first position, the knob 22 abuts against the first positioning end 311. As Figure 7 shown, when the air regulating component 20 is in the second position, the knob 22 abuts against the second positioning end 312.

[0075] Specifically, in use, the user can push the knob 22 by hand to make the air regulating component 20 slide relative to the body 10. And when the knob 22 is pushed to the first positioning end 311 and the knob 22 abuts against the first positioning end 311, it can be judged that the air regulating component 20 is in the first position. When the knob 22 is pushed to the second positioning end 312 and the knob 22 abuts against the second positioning end 312, it can be judged that the air regulating component 20 is in the second position.

[0076] It can be understood that in this embodiment, by arranging the structure for positioning the air regulating component 20 on the cover 30, it is convenient to judge whether the air regulating component 20 is in the first position or the second position, and the cover 30 can be used to protect the air regulating component 20 to avoid the situation that the air regulating component 20 is knocked by external objects and then falls off.

[0077] It should be noted here that the specific position of the positioning through hole 31 can be flexibly selected according to needs. For example, optionally, in one embodiment, as Figure 6 or Figure 8 shown, the positioning through hole 31 is arranged opposite to the air inlet 111, and the knob 22 is located between the first ventilation hole 211 and the second ventilation hole 212 and passes through the positioning through hole 31. As Figure 6 shown, when the air regulating component 20 is in the first position, the first ventilation hole 211 is also communicated with the positioning through hole 31. At this time, the air flow channel 11 is communicated with the external environment through the air inlet 111, the first ventilation hole 211 and the positioning through hole 31. As Figure 8 shown, when the air regulating component 20 is in the second position, the second ventilation hole 212 is also communicated with the positioning through hole 31. At this time, the air flow channel 11 is communicated with the external environment through the air inlet 111, the second ventilation hole 212 and the positioning through hole 31.

[0078] It can be understood that in this embodiment, by arranging the positioning through hole 31 opposite to the air inlet 111, the structure of the aerosol generating device 100 can be made more compact, which is beneficial to the miniaturization design of the aerosol generating device 100.

[0079] Of course, in some other embodiments, the positioning via hole 31 may not be disposed opposite to the air inlet 111. For example, a ventilation via hole may be provided at the position corresponding to the air inlet 111 on the cover body 30, the positioning via hole 31 is located on one side of the ventilation via hole, and the dial 22 passes through the positioning via hole 31.

[0080] Optionally, in one embodiment, please refer to Figure 2 and Figure 4 , the body 10 includes a frame 12, and an air inlet 111 is provided on the frame 12; the air regulating assembly 20 includes a sliding block 23, a first ventilation hole 211 and a second ventilation hole 212 penetrate through the sliding block 23, and a buckle 24 is further provided on the sliding block 23, the buckle 24 passes through the air inlet 111 and is slidably buckled with the frame 12.

[0081] Specifically, in this embodiment, the frame 12 is located at the lower end of the body 10 and is used to support the power supply assembly (including the battery 17, the control board, etc.), and the air inlet 111 penetrates through the frame board of the frame 12 facing the cover body 30. The air regulating assembly 20 includes a sliding block 23, the overall shape of the sliding block 23 is approximately a cuboid, and a first ventilation hole 211 and a second ventilation hole 212 penetrate through the sliding block 23. Importantly, a buckle 24 is further provided on the sliding block 23, the buckle 24 can be integrally formed with the sliding block 23, and a plurality of buckles 24 are provided, for example, two buckles 24 can be provided. After the two buckles 24 pass through the air inlet 111, they are slidably buckled on the frame 12. In this way, the connection between the air regulating assembly 20 and the body 10 can be realized, and the air regulating assembly 20 can slide relative to the body 10, and the structure is simple and easy to produce.

[0082] Optionally, in one embodiment, as Figure 2 and Figure 4 shown, the air regulating assembly 20 further includes a sealing block 25, the sealing block 25 is installed on the sliding block 23, and then the sealing block 25 can slide together with the sliding block 23, and the sealing block 25 is disposed between the sliding block 23 and the frame 12, so as to seal the assembly gap between the sliding block 23 and the frame 12. Importantly, in this embodiment, a first sealing hole 251 and a second sealing hole 252 also penetrate through the sealing block 25, the first sealing hole 251 and the first ventilation hole 211 are correspondingly communicated, and the second sealing hole 252 and the second ventilation hole 212 are correspondingly communicated.

[0083] It can be understood that since the sealing block 25 is compressed between the sliding block 23 and the frame 12, the first sealing hole 251 and the second sealing hole 252 are left on the sealing block 25 for ventilation. The first sealing hole 251 and the second sealing hole 252 are respectively in corresponding communication with the first ventilation hole 211 and the second ventilation hole 212. In this way, it can be ensured that the air flow can only flow into the air inlet 111 through the first ventilation hole 211 or the second ventilation hole 212, preventing the air flow from flowing into the air inlet 111 from other positions, ensuring the accuracy of the air flow rate, and thus achieving precise air regulation.

[0084] Optionally, in one embodiment, as Figure 1 shown, a plurality of heating elements 13 are further provided in the air flow channel 11. The aerosol generating device 100 further includes a control board (not shown) and a control switch (not shown). The plurality of heating elements 13 and the control switch are respectively electrically connected to the control board. The control switch is used to control a first number of heating elements 13 to be energized and heated in the first use mode, and the control switch is also used to control a second number of heating elements 13 to be energized and heated in the second use mode, wherein the first number is greater than the second number.

[0085] Specifically, in this embodiment, as described above, the atomization assembly is provided in the air flow channel 11. The atomization assembly mainly includes the heating elements 13. In this embodiment, there are a plurality of heating elements 13, specifically, there can be two, three, four, five, six, and so on.

[0086] The plurality of heating elements 13 are arranged in the same way, and the plurality of heating elements 13 are respectively electrically connected to the control board. The aerosol generating device 100 further includes a control switch, which is electrically connected to the control board, and the control switch is used to control whether the control board supplies power to the corresponding heating element 13, that is to say, the control switch is used to control whether each heating element 13 is energized and heated.

[0087] Specifically, in this embodiment, in the first use mode (i.e., in the lung inhalation mode), the control switch is used to control a first number of heating elements 13 to be energized and heated, and in the second use mode (i.e., in the mouth inhalation mode), the control switch controls a second number of heating elements 13 to be heated.

[0088] Since the air flow rate required in the lung inhalation mode is greater than that required in the mouth inhalation mode, when the air flow rate is large, more atomization liquid needs to be atomized, and when the air flow rate is small, only less atomization liquid is needed. Therefore, in this embodiment, the first number mentioned above is greater than the second number, that is, in the lung inhalation mode, the control switch controls a larger number of heating elements 13 to be energized and heated to match the larger air flow rate and avoid a too light taste; while in the mouth inhalation mode, the control switch controls a smaller number of heating elements 13 to be energized and heated to match the smaller air flow rate and avoid a too strong taste.

[0089] For example, as Figure 1As shown, there can be four heating elements 13. In the lung-suction mode, the control switch can control the four heating elements 13 to be energized and generate heat. In the mouth-suction mode, the control switch can control two heating elements 13 to be energized and generate heat.

[0090] It should be noted here that the control switch can be a knob, button, toggle switch, etc. exposed on the surface of the body 10, or an induction switch, and controls different numbers of heating elements 13 to be energized and generate heat by sensing the position of the air-adjusting component 20.

[0091] In addition, it should be noted that when the user toggles the air-adjusting component 20 between the first position and the second position to achieve stepless air adjustment, the user can control any number of heating elements 13 to be energized and generate heat according to needs.

[0092] Optionally, in one embodiment, as Figure 1 shown, the air flow channel 11 includes a first sub-channel 112 and a second sub-channel 113. The first sub-channel 112 and the second sub-channel 113 are respectively connected to the air inlet 111, and heating elements 13 are respectively provided in the first sub-channel 112 and the second sub-channel 113. Specifically, one heating element 13 can be provided in each of the first sub-channel 112 and the second sub-channel 113, or multiple heating elements 13 can be provided respectively.

[0093] And in this embodiment, the control switch is used to control the heating elements 13 in the first sub-channel 112 and the second sub-channel 113 to be energized and generate heat in the first use mode; the control switch is also used to control the heating elements 13 in the first sub-channel 112 and / or the second sub-channel 113 to be energized and generate heat in the second use mode.

[0094] Specifically, taking two heating elements 13 provided in each of the first sub-channel 112 and the second sub-channel 113 as an example in this embodiment, in the first use mode (i.e., the lung-suction mode), the control switch controls the heating elements 13 in the first sub-channel 112 and the second sub-channel 113 to be energized and generate heat, that is, all four heating elements 13 are energized and generate heat.

[0095] In the second use mode (i.e., the mouth-suction mode), the control switch can only control one or two heating elements 13 in the first sub-channel 112 to be energized and generate heat, and the two heating elements 13 in the second sub-channel 113 are not energized. Or, the control switch can only control one or two heating elements 13 in the second sub-channel 113 to be energized and generate heat, and the two heating elements 13 in the first sub-channel 112 are not energized. Or, the control switch can also control one heating element 13 in each of the first sub-channel 112 and the second sub-channel 113 to be energized and generate heat, that is, one heating element 13 in each sub-channel is energized and generates heat.

[0096] It should be noted here that when the user toggles the air regulating component 20 between the first position and the second position to achieve stepless air regulation, the user can control the three heating elements 13 to generate heat by means of a control switch. Specifically, two heating elements 13 in the first sub-channel 112 and one heating element 13 in the second sub-channel 113 can be energized to generate heat, or one heating element 13 in the first sub-channel 112 and two heating elements 13 in the second sub-channel 113 can be energized to generate heat.

[0097] Optionally, in one embodiment, as Figure 1 shown, the air flow channel 11 includes a first sub-channel 112 and a second sub-channel 113. That is, the aerosol generating device 100 in this embodiment has a dual airway structure. The first sub-channel 112 and the second sub-channel 113 are respectively communicated with the air inlet 111, and the same number of heating elements 13 are respectively arranged in the first sub-channel 112 and the second sub-channel 113. Specifically, taking the total number of heating elements 13 being four as an example, at this time, two heating elements 13 are arranged in the first sub-channel 112, and two heating elements 13 are also arranged in the second sub-channel 113. The number of heating elements 13 in the first sub-channel 112 and the second sub-channel 113 is the same.

[0098] Crucially, in this embodiment, the control switch is used to control the same number of heating elements 13 in the first sub-channel 112 and the second sub-channel 113 to be energized and generate heat in the first usage mode; the control switch is also used to control the same number of heating elements 13 in the first sub-channel 112 and the second sub-channel 113 to be energized and generate heat in the second usage mode.

[0099] Specifically, still taking the four heating elements 13 in the previous text as an example, as shown before, in the first usage mode (i.e., the lung inhalation mode), the control switch needs to control the four heating elements 13 to be energized and generate heat. At this time, the control switch controls both of the two heating elements 13 in the first sub-channel 112 to be fully energized and generate heat, and at the same time controls both of the two heating elements 13 in the second sub-channel 113 to be fully energized and generate heat. In the second usage mode (i.e., the mouth inhalation mode), the control switch needs to control two heating elements 13 to be energized and generate heat. At this time, the control switch controls one heating element 13 in the first sub-channel 112 to be energized and generate heat, and at the same time controls one heating element 13 in the second sub-channel 113 to be energized and generate heat.

[0100] It can be understood that in this embodiment, by making the control switch control the same number of heating elements 13 in the first sub-channel 112 and the second sub-channel 113 to be energized and generate heat regardless of the mode, this can ensure that the aerosol concentration in the two sub-channels is more uniform and avoid the situation where the aerosol concentration difference in the two sub-channels is too large and affects the taste.
