[0017] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0019] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic atomization device provided in one embodiment of the present application. In this embodiment, an electronic atomization device 100 is provided. The electronic atomization device 100 can be used to heat and atomize an aerosol-generating substrate to form an aerosol for inhalation by a user. Specifically, the electronic atomization device 100 can be an electronic cigarette or a portable medical atomizer, and the aerosol-generating substrate can be tobacco oil, a liquid medicine, or other liquid that can be atomized and inhaled.

[0020] Specifically, the electronic atomization device 100 includes an atomizer 10 and a main unit 20. The atomizer 10 and the main unit 20 are detachably connected. The atomizer 10 is used to heat and atomize the aerosol-generating matrix when powered on. The main unit 20 is provided with a power supply assembly. The atomizer 10 is plugged into a port on one end of the main unit 20 and connected to the power supply assembly in the main unit 20, so that the power supply assembly supplies power to the atomizer 10. When the atomizer 10 needs to be replaced, the atomizer 10 can be removed and a new atomizer 10 installed on the main unit 20, allowing the main unit 20 to be reused.

[0021] Of course, the electronic atomization device 100 also includes other components in the existing electronic atomization device, such as a microphone, a bracket, etc. The specific structures and functions of these components are the same as or similar to those in the prior art. Please refer to the prior art for details and will not be repeated here.

[0022] Specifically, the structure and function of the atomizer 10 can be found in the following description of the atomizer.

[0023] See also Figure 2a and 2b ,in, Figure 2a A schematic structural diagram of an atomizer provided in one embodiment of the present application; Figure 2b This is a structural diagram of an atomizer provided in another embodiment of the present application; in this embodiment, an atomizer 10 is provided, see Figure 2a The atomizer 10 specifically includes a first atomization source 11, a solid smoke base 12 and an air flow channel 14a.

[0024] Among them, the first aerosol-generating matrix is ​​stored in the first aerosol-generating matrix and is used to atomize the first aerosol-generating matrix to form a first aerosol; the solid tobacco base 12 is used to release nicotine. Specifically, the mass percentage of all components in the first aerosol-generating matrix with a boiling point not exceeding 200°C is greater than 50%, that is, more than 50% of all components in the first aerosol-generating matrix have a boiling point not exceeding 200°C. This increases the volatility of the first aerosol-generating matrix, making the first aerosol-generating matrix highly volatile, thereby facilitating atomization and carrying nicotine. At the same time, it reduces the components in the first aerosol-generating matrix that are prone to clogging the solid tobacco base 12, thereby reducing the formation of condensation on the solid tobacco base 12, preventing the condensation from affecting the release of nicotine, and thereby increasing the amount of nicotine released.

[0025] Specifically, the solubility of nicotine in the first aerosol-generating substrate is greater than 10 g nicotine / 100 g substrate, so as to improve the carrying capacity of nicotine in the first aerosol formed by atomization.

[0026] In a specific embodiment, the first aerosol-generating matrix includes one or any combination of propylene glycol, water, and ethanol, and the mass percentage of one or any combination of propylene glycol, water, and ethanol is greater than 50%, that is, more than 50% of the components in the first aerosol-generating matrix are one or any combination of propylene glycol, water, and ethanol. Specifically, more than 50% of the components in the first aerosol-generating matrix can be propylene glycol, so as to utilize a high proportion of propylene glycol to enhance the carrying capacity of the first aerosol formed by atomization to carry nicotine, and by reducing the proportion of high-boiling-point, non-volatile substances (i.e., glycerol) in the first aerosol-generating matrix, the condensation amount of the first aerosol in the solid tobacco base 12 is reduced, thereby reducing the probability of the problem of nicotine release decreasing with the increase in the number of puffs.

[0027] It is understood that, in a specific embodiment, the first aerosol generating matrix further includes other ingredients with a mass percentage of less than 50%, such as glycerol and flavors and fragrances.

[0028] In a specific embodiment, the first atomization source 11 specifically includes a first liquid storage cavity 111 and a first atomization core 112 .

[0029] The first aerosol generating substrate is specifically stored in the first liquid storage cavity 111 , which is in communication with the first atomizing core 112 ; the first atomizing core 112 is configured to atomize the first aerosol generating substrate that has arrived at the first atomizing core 112 from the first liquid storage cavity 111 to form a first aerosol.

[0030] Specifically, the first atomizing core 112 includes a first porous matrix and a first heating element. The first porous matrix is ​​connected to the first liquid storage cavity 111 and is used to guide the first aerosol generating matrix, that is, to guide the first aerosol generating matrix in the first liquid storage cavity 111 to the first porous matrix; the first heating element is used to heat and atomize the first aerosol generating matrix on the first porous matrix when powered on; wherein, the first porous matrix can be a porous ceramic, and the first heating element can be a heating film arranged on the first porous matrix.

[0031] In a specific embodiment, the above-mentioned atomizer 10 further includes a shell 14 and a mouthpiece 15; wherein the shell 14 forms an air flow channel 14a and a receiving chamber 14b, the air flow channel 14a has an air outlet, and the mouthpiece 15 is connected to the air outlet of the air flow channel 14a to inhale the aerosol formed by atomization; in a specific embodiment, the first atomization core 112 and the solid tobacco base 12 are specifically located in the air flow channel 14a, and the solid tobacco base 12 is located between the first atomization core 112 and the air outlet, so that the first aerosol formed by atomization of the first atomization core 112 passes through the solid tobacco base 12 and carries out the nicotine released by the solid tobacco base 12; the first liquid storage chamber 111 is located in the receiving chamber 14b.

[0032] In one embodiment, the atomizer 10 may further include a flavor capsule 120, in which the solid tobacco base 12 may be specifically accommodated; and the flavor capsule 120 may be specifically detachably installed in the airflow channel 14a, so that the solid tobacco base 12 is disposed in the airflow channel 14a, thereby facilitating replacement of the flavor capsule 120; for example, after the solid tobacco base 12 is used up, it is convenient to replace it with a new solid tobacco base 12; specifically, the flavor capsule 120 may further include other aroma or flavor regulating substances to adjust the aerosol concentration, temperature, etc.

[0033] For details, see Figure 3 , Figure 3 This is a schematic structural diagram of a flavor capsule provided in one embodiment of the present application; the flavor capsule 120 may include a body 121 , a first cover 122 and a second cover 123 .

[0034] The elastic body 121 may be a columnar structure; the elastic body 121 is formed with a receiving cavity, and the receiving cavity has a first cavity opening and a second cavity opening; in a specific embodiment, the material of the elastic body 121 may be a paper material; the solid tobacco base 12 is specifically stored in the receiving cavity for releasing the regulated aerosol; the first cover 122 is provided on the first cavity opening, and a plurality of first air holes are provided on the first cover 122 to allow the first aerosol to enter the receiving cavity through the first air holes; the second cover 123 is provided on the second cavity opening, and a plurality of second air holes are provided on the second cover 123 air holes, so that the first aerosol carrying nicotine can flow out of the accommodating cavity through the second air holes; specifically, the material of the first cover 122 and / or the second cover 123 can be metal, and the regulating matrix can be a flavoring substance, such as tobacco particles; a plurality of first air holes can be evenly distributed on the first cover 122, so that the first aerosol can be better mixed with the nicotine released by the solid tobacco base 12, thereby improving the mixing uniformity and enhancing the user's smoking taste; the second air holes can also be evenly distributed on the second cover 123, which is not limited in this embodiment.

[0035] The atomizer 10 provided in this embodiment is provided with a first liquid storage cavity 111, a first atomizing core 112 and a solid tobacco base 12; wherein the first liquid storage cavity 111 stores a first aerosol generating matrix, the first atomizing core 112 is used to atomize the first aerosol generating matrix to form a first aerosol, and the solid tobacco base 12 is used to release nicotine; wherein, since the mass percentage of all components with a boiling point not exceeding 200° C. in the first aerosol generating matrix is ​​greater than 50%, in order to improve the first aerosol generating matrix, the first aerosol generating matrix is ​​provided with a first aerosol generating matrix. While increasing the volatility of the sol-generating matrix, the components in the first aerosol-generating matrix that are likely to clog the solid tobacco base 12 are reduced, thereby reducing the formation of condensate on the solid tobacco base 12. In addition, by providing an airflow channel 14a, the airflow channel 14a includes an air outlet, and the first atomizing core 112 and the solid tobacco base 12 are located in the airflow channel 14a, with the solid tobacco base 12 located between the first atomizing core 112 and the air outlet, the first aerosol passes through the solid tobacco base 12 and carries out the nicotine released by the solid tobacco base 12.

[0036] In one embodiment, see Figures 2b to 4 The atomizer 10 further includes a second atomization source 13, which stores a second aerosol-generating matrix and is used to atomize the second aerosol-generating matrix to form a second aerosol containing stabilizer molecules. In a specific embodiment, the second atomization source 13 is located in the airflow channel 14a and between the solid tobacco base 12 and the air outlet. After the first aerosol carries out nicotine, it mixes with the second aerosol atomized by the second atomization source 13, so that the nicotine and the stabilizer molecules are combined to form new nicotine aerosol particles. At the same time, the first aerosol is heated and atomized by the second atomization source 13 to increase the atomization amount and enhance the user's puffing taste. The stability of the new nicotine aerosol particles is higher than that of gaseous nicotine.

[0037] Specifically, the stabilizer molecules may be organic acid molecules; the first aerosol-generating substrate and the second aerosol-generating substrate may contain nicotine or not contain nicotine. In a preferred embodiment, both the first aerosol-generating substrate and the second aerosol-generating substrate do not contain nicotine or contain only a small amount of nicotine.

[0038] In order to improve the stability of the generated second aerosol and to facilitate its reaction with nicotine, the volatility of the second aerosol-generating substrate is lower than that of the first aerosol-generating substrate. Specifically, the mass percentage of all components in the second aerosol-generating substrate having a boiling point exceeding 250°C is greater than 50%; that is, more than 50% by mass of the components in the second aerosol-generating substrate have a boiling point exceeding 250°C.

[0039] Specifically, the component with a mass percentage exceeding 50% in the second aerosol-generating matrix may be glycerol. By increasing the proportion of the high-boiling-point substance (glycerol) in the second atomization source 13, more gaseous nicotine is absorbed, so that the stabilizer molecules in the second aerosol, i.e., the organic acid molecules, react with nicotine to form nicotine aerosol particles that are more stable than gaseous nicotine. This reduces the irritation of the gaseous nicotine to the user's throat, locks in the gaseous nicotine, and prevents it from being lost, thereby increasing the nicotine content in the aerosol inhaled by the user and enhancing the user's satisfaction.

[0040] Among them, since the second atomization source 13 is downstream of the solid tobacco base 12, that is, after the nicotine is released, new nicotine aerosol particles with higher stability than gaseous nicotine are formed by adding organic acid. Compared with gaseous nicotine, this can not only reduce the irritation of nicotine to the user's throat, but also lock the released nicotine to ensure the release amount of nicotine and enhance the user experience. In addition, the nicotine salt will not be deposited in the flavor capsule 120, thereby not affecting the release amount of nicotine in the solid tobacco base 12 in the flavor capsule 120, that is, it will not aggravate the problem of nicotine release attenuation.

[0041] In a specific embodiment, the boiling point of each component of the first aerosol-generating substrate does not exceed 200°C, and the boiling point of at least one component of the second aerosol-generating substrate exceeds 250°C.

[0042] Of course, in specific embodiments, the second aerosol-generating matrix may also include other ingredients in an amount less than 50% by weight, such as a small amount of propylene glycol and 0-10% by weight of an organic acid. Specifically, the second aerosol-generating matrix may be composed of propylene glycol, glycerol, an organic acid, and flavors.

[0043] Specifically, the second atomization source 13 includes a second liquid storage cavity 131 and a second atomization core 132 .

[0044] The second aerosol-generating substrate is specifically stored in the second liquid storage chamber 131. The second atomizer core 132 is in communication with the second liquid storage chamber 131 and is used to atomize the second aerosol-generating substrate that reaches the second atomizer core 132 from the second liquid storage chamber 131 to form a second aerosol containing stabilizer molecules. In a specific embodiment, the second liquid storage chamber 131 is located within the receiving chamber 14b. The second atomizer core 132 is located within the airflow channel 14a and between the solid tobacco base 12 and the air outlet, that is, between the flavor capsule 120 and the air outlet. It can be understood that at this time, the second atomizer core 132 is located downstream of the solid tobacco base 12. This effectively prevents the more stable new nicotine aerosol particles from affecting the nicotine release from the solid tobacco base 12, ensures that the released nicotine is inhaled to the greatest extent possible by the user, and thereby effectively increases the nicotine content in the aerosol inhaled by the user.

[0045] Specifically, the second atomizer core 132 includes a second porous substrate and a second heating element. The second porous substrate is in communication with the second liquid storage cavity 131 and is used to guide the second aerosol-generating substrate, that is, to guide the second aerosol-generating substrate in the second liquid storage cavity 131 to the second porous substrate. The second heating element is used to heat and atomize the second aerosol-generating substrate on the second porous substrate when powered. The second porous substrate can be porous ceramic, and the second heating element can be a heating film disposed on the second porous substrate.

[0046] Specifically, the first aerosol formed by the first atomization source 11 carries nicotine and reaches the second atomization core 132. The second atomization core 132 performs secondary atomization and aerosol rectification on the first aerosol carrying nicotine, and fully mixes it with the generated second aerosol containing organic acid molecules to form new nicotine aerosol particles that are more stable than gaseous nicotine. Compared with gaseous nicotine, this can effectively reduce the irritation of nicotine to the user's throat and make the taste smoother.

[0047] In one embodiment, see Figure 4 , Figure 4This is a schematic diagram of the structure of an atomizer according to another embodiment of the present application. The atomizer 10 further includes a heating assembly 16. The heating assembly 16 may be disposed within the airflow channel 14a and surround the solid tobacco base 12. The heating assembly 16 is configured to heat the solid tobacco base 12 when powered, thereby increasing the nicotine release rate of the solid tobacco base 12. Furthermore, because the solid tobacco base 12 is disposed upstream of the second atomizer core 132, i.e., away from the mouthpiece 15, the first aerosol atomized by the first atomizer core 11, after carrying nicotine, still needs to pass through the second atomizer core 132 before entering the mouthpiece 15 for inhalation by the user. Compared to a solution in which the first aerosol carrying nicotine directly communicates with the mouthpiece 15 for direct inhalation by the user, the atomizer 10 can further increase the heating temperature of the heating assembly 16, thereby increasing the temperature within the solid tobacco base 12, while ensuring a relatively suitable aerosol temperature for inhalation by the user. This further increases the nicotine release rate and / or the release rate of other components within the flavor capsule 120, thereby providing a better inhalation experience.

[0048] It is understandable that if the mouthpiece 15 directly inhales the solid tobacco base 12, the heating temperature of the solid tobacco base 12 by the heating component 16 cannot be maintained at a high temperature, which will cause the heating component 16 to burn the mouth due to the high temperature. However, the atomizer 10 of the present application, by arranging the solid tobacco base 12 between the first atomization core 112 and the second atomization core 132, can make the heating of the heating component 16 higher, so as to heat the solid tobacco base 12 to a higher temperature, thereby improving the release efficiency of nicotine and flavors.

[0049] In a specific embodiment, the heating component 16 may be annular, and may specifically surround the outer side of the flavor capsule 120 and be arranged along the circumferential direction thereof to improve the uniformity of heating the solid tobacco base 12 in the flavor capsule 120; in a specific embodiment, the inner and outer side walls of the heating component 16 respectively abut against the outer side wall of the flavor capsule 120 and the inner side wall of the air flow channel 14a to prevent the first aerosol from entering the position where the second atomizing core 132 is located from the gap between the heating component 16 and the flavor capsule 120 and / or from the gap between the heating component 16 and the air flow channel 14a, thereby ensuring that the first aerosol can be mixed with the adjusted aerosol to ensure the user's puffing taste.

[0050] Of course, in a specific embodiment, the temperature of the first aerosol can also be used to directly heat the solid tobacco base 12 to promote the release of nicotine.

[0051] In a specific embodiment, the atomizer 10 further includes a controller 17 for controlling the heating component 16 to heat the solid tobacco base 12 in response to a heating signal, and for controlling the first atomizer core 112 and the second atomizer core 132 to perform atomization in response to a user's usage signal.

[0052] Specifically, in one embodiment, the atomizer 10 may further include a first detection element, a second detection element, and a third detection element (not shown).

[0053] The first detection element is used to detect and send a heating signal of the solid tobacco base 12; the controller 17 responds to the heating signal and controls the heating power of the heating component 16; in a specific embodiment, the heating signal can be generated when the heating temperature of the heating component 16 is lower than a preset temperature.

[0054] The second detection element is used to detect and send a first start-up signal to the first atomization source 11. The controller 17 responds to the first start-up signal and controls the first atomization source 11 to turn on, that is, controls the first atomization core 112 to heat and atomize the first aerosol generating matrix; wherein, the first start-up signal can specifically be a user's usage signal, for example, it can be a power-on signal, a user's inhalation signal or other control signal.

[0055] The third detection element is used to detect and send a second start-up signal of the second atomization source 13. The controller 17 responds to the second start-up signal and controls the second atomization source 13 to turn on, that is, controls the second atomization core 132 to heat and atomize the second aerosol generating matrix; wherein, the second start-up signal can be a user's inhalation signal, a user's touch signal, or a time signal generated after the first atomization source 11 is turned on for a preset time.

[0056] Specifically, when the above-mentioned start signal is a suction signal, the detection element may be an airflow sensor, such as a microphone, which sends the suction signal to the controller 17; when the start signal is a user touch signal, the detection element may be a touch sensor.

[0057] Of course, in other embodiments, the same detection element may be used to detect and send a start signal for the first atomization source 11 and the second atomization source 13. The start signal may be a user's usage signal, that is, when the user's usage signal is detected, the detection element sends the user's usage signal, and the controller 17 responds to the user's usage signal to control the first atomization core 112 and the second atomization core 132 to heat and atomize.

[0058] The atomizer 10 provided in this embodiment further provides a second atomization source 13, and the second atomization core 123 of the second atomization source 13 is arranged in the air flow channel 14a and located between the solid tobacco base 12 and the air outlet, so that the second atomization core 132 atomizes the second aerosol to generate a matrix to form a second aerosol containing stabilizer molecules. At the same time, by positioning the solid tobacco base 12 between the first atomization core 112 and the second atomization core 122, the first aerosol passes through the solid tobacco base 12 and carries out nicotine, and mixes with the second aerosol, so that the nicotine combines with the stabilizer molecules to form new nicotine aerosol particles. In particular, since the stabilizer molecules combine with the released nicotine downstream of the solid tobacco base 12 to form new nicotine aerosol particles, not only can the irritation of nicotine to the user's throat be reduced, but the stable nicotine aerosol particles will not be deposited on the surface of the solid tobacco base 12 and hinder the release of nicotine, thereby effectively increasing the nicotine release amount and ensuring the released nicotine. In addition, since only the first aerosol among the first aerosol and the second aerosol generated by the atomizer 10 passes through the solid tobacco base 12, that is, only a part of the aerosol formed by atomization by the atomizer 10 passes through the solid tobacco base 12, compared with the solution in which all the aerosol formed by atomization by the atomizer 10 needs to pass through the solid tobacco base 12, the condensation amount of the aerosol in the solid tobacco base 12 is effectively reduced, and the condensation liquid is reduced. The effect on the nicotine release amount is achieved, thereby effectively ensuring the nicotine release amount. At the same time, the solid tobacco base 12 is heated by providing the heating component 16. Since the solid tobacco base 12 is provided between the first atomizer core 112 and the second atomizer core 132, compared with the solution without providing the second atomizer core 132, the solid tobacco base 12 is farther away from the mouthpiece 15, thereby effectively increasing the heating temperature of the heating component 16, thereby further increasing the release amount of the regulated aerosol including nicotine.

[0059] The working principle of the atomizer 10 is described in detail below.

[0060] After receiving the start signal of the atomizer 10, the controller 17 controls the heating component 16 to start heating the solid tobacco base 12 and releasing the adjusted aerosol; specifically, during the heating process, the temperature of the solid tobacco base 12 gradually increases and is maintained at a relatively constant temperature; after receiving the user's inhalation signal, the controller 17 controls the first atomizing core 112 and the second atomizing core 132 to start respectively, so as to heat the first aerosol generating matrix through the first atomizing core 112 to generate a first aerosol, and to heat and atomize the second aerosol generating matrix through the second atomizing core 132 to generate a second aerosol including organic acid molecules; in the specific working process, the first atomizing core 112 and the second atomizing core 132 are respectively controlled to start. An aerosol enters the solid tobacco base 12 from the first air vent of the first cover 122. The first aerosol carries nicotine and reaches the position of the second atomizer core 132 and mixes with the second aerosol. The nicotine carried by the first aerosol reacts with the organic acid molecules in the second aerosol to generate new nicotine aerosol particles that are more stable than gaseous nicotine, thereby reducing the irritation of gaseous nicotine to the user's throat and locking the nicotine to ensure that the released nicotine can be inhaled by the user to the greatest extent. At the same time, the first aerosol is secondary atomized by the second atomizer core 132 and mixed with the second aerosol, and then the user inhales through the mouthpiece 15.

[0062] Step S11: atomizing a first aerosol-generating substrate to form a first aerosol.

[0063] Specifically, the mass percentage of all components in the first aerosol-generating matrix having a boiling point not exceeding 200°C is greater than 50%. That is, more than 50% of all components in the first aerosol-generating matrix have a boiling point not exceeding 200°C. This increases the volatility of the first aerosol-generating matrix, making it more volatile and facilitating atomization and nicotine transport. Furthermore, it reduces the number of components in the first aerosol-generating matrix that are susceptible to clogging the solid tobacco matrix, thereby reducing the formation of condensate on the solid tobacco matrix and preventing the condensate from affecting nicotine release, thereby increasing the amount of nicotine released.

[0064] Specifically, the solubility of nicotine in the first aerosol-generating substrate is greater than 10 g nicotine / 100 g substrate, so as to improve the carrying capacity of nicotine in the first aerosol formed by atomization.

[0065] In a specific embodiment, the first aerosol-generating matrix includes one or any combination of propylene glycol, water, and ethanol, and the mass percentage of one or any combination of propylene glycol, water, and ethanol is greater than 50%, that is, more than 50% of the components in the first aerosol-generating matrix are one or any combination of propylene glycol, water, and ethanol. Specifically, more than 50% of the components in the first aerosol-generating matrix can be propylene glycol, so as to utilize a high proportion of propylene glycol to enhance the carrying capacity of the first aerosol formed by atomization to carry nicotine, and by reducing the proportion of high-boiling-point, non-volatile substances (i.e., glycerol) in the first aerosol-generating matrix, the condensation amount of the first aerosol in the solid tobacco base 12 is reduced, thereby reducing the probability of the problem of nicotine release decreasing with the increase in the number of puffs.

[0066] It is understood that, in a specific embodiment, the first aerosol generating matrix further includes other ingredients with a mass percentage of less than 50%, such as glycerol and flavors and fragrances.

[0067] Specifically, step S11 can be performed by the first atomization core 112 of the first atomization source 11; wherein, the specific structure and function of the first atomization source 11 can refer to the relevant description of the first atomization source 11 in the atomizer 10 provided in the above embodiment, and the same or similar technical effects can be achieved, which will not be repeated here.

[0068] Step S12: allowing the first aerosol to pass through the solid tobacco base and carry out nicotine released by the solid tobacco base.

[0069] During the specific implementation process, the solid tobacco base 12 may be heated to release nicotine, which can further increase the amount of nicotine released. The specific working principle can be found in the above-mentioned related text description and will not be repeated here.

[0070] The aerosol generation method provided in this embodiment forms a first aerosol by atomizing a first aerosol-generating substrate. The mass percentage of all components in the first aerosol-generating substrate with a boiling point not exceeding 200° C. is set to be greater than 50%. This increases the volatility of the first aerosol-generating substrate while reducing components in the first aerosol-generating substrate that are susceptible to clogging the solid tobacco base 12, thereby reducing the formation of condensate on the solid tobacco base 12. Simultaneously, the first aerosol passes through the solid tobacco base 12, carrying away nicotine released by the solid tobacco base 12 for inhalation by the user. Furthermore, by heating the solid tobacco base 12, the nicotine release amount can be effectively increased.

[0071] In one embodiment, the aerosol generation method may further include atomizing a second aerosol-generating matrix to form a second aerosol containing stabilizer molecules. Specifically, this step may be performed by the second atomizing core 132 of the second atomizing source 13. The specific structure and function of the second atomizing source 13 may be referred to in the description of the second atomizing source 13 in the atomizer 10 provided in the above embodiment, and the same or similar technical effects can be achieved, so further description is omitted here. The stabilizer molecules may be organic acid molecules.

[0072] In a specific implementation, the volatility of the second aerosol-generating substrate is less than that of the first aerosol-generating substrate. Specifically, the mass percentage of all components in the second aerosol-generating substrate with a boiling point exceeding 250°C is greater than 50%. That is, more than 50% by mass of the components in the second aerosol-generating substrate have a boiling point exceeding 250°C, thereby improving the stability of the second aerosol and facilitating better reaction with nicotine.

[0073] Specifically, the component of the second aerosol-generating matrix that accounts for more than 50% by mass may be glycerol. It is understood that by increasing the proportion of the high-boiling-point substance (e.g., glycerol) in the second aerosol-generating matrix, the second aerosol containing organic acid molecules formed by atomizing the second aerosol-generating matrix can absorb more gaseous nicotine, so that the organic acid molecules react with nicotine to form new nicotine aerosol particles that are more stable than gaseous nicotine.

[0074] Of course, in specific embodiments, the second aerosol-generating matrix may also include other ingredients in an amount less than 50% by weight, such as a small amount of propylene glycol and 0-10% by weight of an organic acid. Specifically, the second aerosol-generating matrix is ​​composed of propylene glycol, glycerol, an organic acid, and flavors.

[0075] Specifically, in one embodiment, after step S12, the step further includes mixing with the second aerosol so that nicotine combines with stabilizer molecules to form new nicotine aerosol particles that are more stable than nicotine. That is, the first aerosol carrying nicotine is mixed with the second aerosol so that nicotine combines with stabilizer molecules to form new nicotine aerosol particles that are more stable than nicotine.

[0076] Specifically, the nicotine carried by the first aerosol combines with the stabilizer molecules to form new nicotine aerosol particles that are more stable than nicotine, thereby reducing the irritation of gaseous nicotine to the user's throat and locking the gaseous nicotine to prevent loss, thereby increasing the amount of nicotine inhaled by the user and enhancing the user's satisfaction.

[0077] Among them, since this process is after the nicotine is released and then combines with the second aerosol containing organic acid molecules to form new nicotine aerosol particles that are more stable than gaseous nicotine, this not only reduces the irritation of gaseous nicotine to the user's throat, but also locks the gaseous nicotine to prevent loss, thereby increasing the amount of nicotine inhaled by the user and enhancing the user's satisfaction. In addition, the nicotine aerosol particles will not be deposited on the surface of the solid tobacco base 12, and will not affect the nicotine release amount, that is, it will not aggravate the problem of nicotine release attenuation, thereby effectively increasing the nicotine content in the aerosol inhaled by the user.

[0078] During the specific implementation process, the second atomization core 132 of the second atomization source 13 can also be used to perform secondary atomization on the first aerosol carrying nicotine; specifically, the second heating element in the second atomization source 13 is used to further atomize the first aerosol carrying nicotine to increase the atomization amount, so that the user can obtain a better puffing experience.

[0079] The aerosol generation method provided in this embodiment further atomizes the second aerosol to generate a matrix to form a second aerosol containing stabilizer molecules. The first aerosol then passes through the solid tobacco base 12, carrying nicotine released by the solid tobacco base 12 and mixing with the second aerosol, so that the nicotine combines with the stabilizer molecules to form new nicotine aerosol particles that are more stable than nicotine. This method not only reduces the irritation of the gaseous nicotine to the user's throat but also locks the gaseous nicotine to prevent loss, thereby increasing the nicotine content in the aerosol inhaled by the user and enhancing the user's satisfaction. In addition, the nicotine aerosol particles will not deposit on the surface of the solid tobacco base 12, and will not affect the nicotine release, that is, it will not aggravate the problem of nicotine release attenuation, thereby effectively increasing the nicotine release.

Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
