[0019] 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. Among them, the atomizer 10 is used to heat and atomize the aerosol generating matrix when powered on; a power supply component is arranged in the main unit 20, and the atomizer 10 is plugged into one end port of the main unit 20 and connected to the power supply component in the main unit 20 to supply power to the atomizer 10 through the power supply component. When the atomizer 10 needs to be replaced, the atomizer 10 can be disassembled and a new atomizer 10 can be installed on the main unit 20 to realize the reuse of the main unit 20.

[0020] 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 of the prior art. For details, reference can be made to the prior art and will not be elaborated here.

[0021] Specifically, for the structure and function of the above atomizer 10, reference can be made to the relevant description of the atomizer in the following embodiments.

[0022] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an atomizer provided by an embodiment of the present application; in this embodiment, an atomizer 10 is provided, which specifically includes a first atomization source 11, a solid tobacco base 12, and a second atomization source 13.

[0023] Among them, the first atomization source 11 stores a first aerosol generating matrix and is used to atomize the first aerosol generating matrix to form a first aerosol; the second atomization source 13 includes a second aerosol generating matrix and is used to atomize the second aerosol generating matrix to form a second aerosol containing stabilizer molecules; the solid tobacco base 12 is used to release nicotine and is arranged on the airflow path of the first atomization source 11 and the second atomization source 13, so that the first aerosol passes through the solid tobacco base 12 and brings out nicotine and then mixes with the second aerosol, and the nicotine combines with the stabilizer molecules to form new nicotine aerosol particles; among them, the stability of the formed new nicotine aerosol particles is higher than that of gaseous nicotine; specifically, the stabilizer molecules can be organic acid molecules; the first aerosol generating matrix and the second aerosol generating matrix may or may not contain nicotine components. In a preferred embodiment, both the first aerosol generating matrix and the second aerosol generating matrix do not contain nicotine or contain only a small amount of nicotine.

[0024] In a specific embodiment, the atomizer 10 further specifically includes a housing 14 and a mouthpiece 15; wherein, the housing 14 forms an air flow channel 14a and a receiving cavity 14b, the air flow channel 14a has an air outlet, and the mouthpiece 15 is communicated with the air outlet of the air flow channel 14a to suck the aerosol formed by atomization; in a specific embodiment, the first atomization source 11, the solid tobacco base 12 and the second atomization source 13 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 second atomization source 13, and the second atomization source 13 is located between the solid tobacco base 12 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 brings out the nicotine released by the solid tobacco base 12, and then is mixed with the second aerosol.

[0025] Among them, the solubility of the first aerosol generation matrix in nicotine is greater than 10 g of nicotine / 100 g of matrix to improve the nicotine-carrying ability of the first aerosol formed by atomization; specifically, the mass percentage of all components in the first aerosol generation 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 generation matrix have a boiling point not exceeding 200 °C, so as to improve the volatility of the first aerosol generation matrix, make the first aerosol generation matrix have strong volatility, facilitate atomization and nicotine carrying, while reducing the components in the first aerosol generation matrix that are easy to block the solid tobacco base 12, thereby reducing the formation of condensate on the solid tobacco base 12 and avoiding the influence of condensate on the release of nicotine, so as to increase the nicotine release amount.

[0026] In a specific embodiment, the mass percentage of one or any combination of propylene glycol, water, and ethanol in the first aerosol generation matrix is greater than 50%, that is, more than 50% of the components in the first aerosol generation matrix are one or any combination of propylene glycol, water, and ethanol; specifically, more than 50% of the components in the first aerosol generation matrix can be propylene glycol, so as to utilize the high proportion of propylene glycol to enhance the nicotine-carrying ability of the first aerosol formed by atomization, and by reducing the proportion of high-boiling and difficult-to-volatilize substances (such as glycerol) in the first aerosol generation matrix, reduce the condensation amount of the first aerosol in the solid tobacco base 12, and further reduce the probability of the problem that the nicotine release amount decays with the increase of the number of puffs.

[0027] It can be understood that in a specific embodiment, the first aerosol generation matrix further specifically includes other components with a mass percentage less than 50%, such as glycerol and flavoring agents.

[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] Among them, the first aerosol - generating matrix is specifically stored in the first liquid - storage cavity 111, and the first liquid - storage cavity 111 is in communication with the first atomizing core 112; the first atomizing core 112 is used to atomize the first aerosol - generating matrix reaching the first atomizing core 112 from the first liquid - storage cavity 111 to form the first aerosol; in a specific embodiment, the first liquid - storage cavity 111 is located in the receiving cavity 14b, the first atomizing core 112 is located in the air - flow channel 14a, and is on the side of the solid tobacco base 12 away from the air outlet.

[0030] Specifically, the first atomizing core 112 includes a first porous matrix and a first heating element. The first porous matrix is in communication with 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; among them, the first porous matrix can be porous ceramic, and the first heating element can be a heating film disposed on the first porous matrix.

[0031] In one embodiment, the atomizer 10 may further include a flavor capsule 120. The solid tobacco base 12 can be specifically accommodated in the flavor capsule 120; and the flavor capsule 120 is specifically detachably installed in the air - flow channel 14a to arrange the solid tobacco base 12 in the air - flow channel 14a, facilitating the 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 fragrance or flavor - regulating substances to regulate the aerosol concentration, temperature, etc.

[0032] Specifically, refer to Figure 3 , Figure 3 which is a schematic structural diagram of the flavor capsule provided by an embodiment of the present application; the flavor capsule 120 may include a bullet body 121, a first cover body 122, and a second cover body 123.

[0033] The body 121 may be a columnar structure; the 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 body 121 may be made of paper; the solid tobacco base 12 is specifically stored in the receiving cavity; the first cover 122 is covered with the first cavity opening, and a plurality of first air holes are opened on the first cover 122, so that the first aerosol enters the receiving cavity through the first air holes; the second cover 123 is covered with the second cavity opening, and a plurality of first air holes are opened on the second cover 123; The second air holes are arranged on the first cover 122 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; 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.

[0034] In order to improve the stability of the generated second aerosol and react well with nicotine, the volatility of the second aerosol generating matrix is less than the volatility of the first aerosol generating matrix; specifically, the mass percentage of all components with a boiling point exceeding 250° C. in the second aerosol generating matrix is greater than 50%; that is, the boiling point of the components with a mass percentage exceeding 50% in the second aerosol generating matrix exceeds 250° C.

[0035] Specifically, the component with a mass percentage exceeding 50% in the second aerosol-generating matrix may be glycerol, so as to absorb more gaseous nicotine by increasing the proportion of the high-boiling-point substance (glycerol) in the second atomization source 13, so that the stabilizer molecules in the second aerosol, that is, the organic acid molecules, react with nicotine and form nicotine aerosol particles with higher stability than gaseous nicotine, thereby reducing the irritation of the gaseous nicotine to the throat of the user, and locking the gaseous nicotine to prevent loss, so as to increase the nicotine content in the aerosol inhaled by the user and enhance the user's satisfaction.

[0036] 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, it 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's experience. In addition, 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.

[0037] In a specific embodiment, the boiling points of the components in the first aerosol - generating matrix do not exceed 200°C, and the boiling point of at least one component in the second aerosol - generating matrix exceeds 250°C.

[0038] Of course, in a specific embodiment, the second aerosol - generating matrix may further include other components with a mass percentage lower than 50%, such as a small amount of propylene glycol and organic acids with a mass percentage of 0 - 10%. Specifically, the second aerosol - generating matrix may be composed of propylene glycol, glycerol, organic acids, and flavoring agents.

[0039] Specifically, the second atomization source 13 specifically includes a second liquid - storage cavity 131 and a second atomization core 132.

[0040] Specifically, the second aerosol - generating matrix is specifically stored in the second liquid - storage cavity 131. The second atomization core 132 is in communication with the second liquid - storage cavity 131 and is used to atomize the second aerosol - generating matrix reaching the second atomization core 132 from the second liquid - storage cavity 131 to form a second aerosol containing stabilizer molecules. In a specific embodiment, the second liquid - storage cavity 131 is located in the receiving cavity 14b, and the second atomization core 132 is located in the air - flow 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 atomization core 132 is in the downstream position of the solid tobacco base 12, which can effectively avoid the influence of new nicotine aerosol particles with higher stability on the release amount of nicotine in the solid tobacco base 12 and ensure that the released nicotine is maximally sucked by the user, thereby increasing the nicotine content in the aerosol sucked by the user.

[0041] Specifically, the second atomization core 132 includes a second porous matrix and a second heating element. The second porous matrix is in communication with the second liquid - storage cavity 131 and is used to direct the flow of the second aerosol - generating matrix, that is, to direct the second aerosol - generating matrix in the second liquid - storage cavity 131 to the second porous matrix. The second heating element is used to heat and atomize the second aerosol - generating matrix on the second porous matrix when powered on. Among them, the second porous matrix can be porous ceramics, and the second heating element can be a heating film disposed on the second porous matrix.

[0042] Specifically, after the first aerosol formed by the first atomization source 11 carries nicotine and reaches the second atomization core 131, the second atomization core 132 in the second atomization source 13 will perform secondary atomization and aerosol rectification on the first aerosol carrying nicotine and fully mix it with the second aerosol containing organic acid molecules generated by the second atomization source 13 to form new nicotine aerosol particles with higher stability than gaseous nicotine. Compared with gaseous nicotine, it can effectively reduce the irritation of nicotine to the user's throat and make the taste smoother.

[0043] In one embodiment, referring to Figure 4 , Figure 4 which is a schematic structural diagram of an atomizer provided in another embodiment of the present application; the atomizer 10 further includes a heating component 16; the heating component 16 can be arranged in the air flow channel 14a and surround the solid tobacco substrate 12, and is used to heat the solid tobacco substrate 12 when powered on, so as to increase the release amount of nicotine in the solid tobacco substrate 12; wherein, since the solid tobacco substrate 12 is arranged upstream of the second atomization core 132, that is, at a position away from the mouthpiece 15, the first aerosol atomized by the first atomization core 11 still needs to pass through the second atomization core 132 of the second atomization source 13 after carrying nicotine before entering the mouthpiece 15 to be sucked by the user. Compared with the scheme that the first aerosol directly communicates with the mouthpiece 15 after carrying nicotine so that the user directly sucks the second aerosol, the atomizer 10 can further increase the heating temperature of the heating component 16 on the premise of ensuring that the temperature of the aerosol sucked by the user is relatively appropriate, so as to increase the temperature in the solid tobacco substrate 12, thereby further increasing the release amount of nicotine and / or the release amount of other components in the flavor capsule 120, and then obtaining a better sucking experience.

[0044] It can be understood that if the mouthpiece 15 directly sucks the solid tobacco substrate 12, the heating temperature of the heating component 16 for the solid tobacco substrate 12 cannot be maintained at a high temperature, which will cause the problem of the heating component 16 being too hot to touch; while for the atomizer 10 of the present application, by arranging the solid tobacco substrate 12 between the first atomization core 112 and the second atomization core 112, the heating of the heating component 16 can be higher, so as to heat the solid tobacco substrate 12 to a higher temperature, thereby improving the release efficiency of nicotine and flavoring agents.

[0045] In a specific embodiment, the heating component 16 can be annular, and it can specifically surround the outside of the flavor capsule 120 and be arranged along its circumferential direction for one week to improve the heating uniformity of the solid tobacco substrate 12 in the flavor capsule 120; in a specific embodiment, the inner and outer side walls of the heating component 16 are respectively in contact with the outer side wall of the flavor capsule 120 and the inner side wall of the air flow channel 14a to avoid the problem that the first aerosol enters the position where the second atomization 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, so as to ensure that the first aerosol can be mixed with the adjusted aerosol, so as to ensure the sucking taste of the user.

[0046] Of course, in a specific embodiment, the temperature of the first aerosol can also be directly used to heat the solid tobacco substrate 12 to promote the release of nicotine.

[0047] In a specific embodiment, the atomizer 10 further includes a controller 17, which responds to a heating signal to control the heating component 16 to heat the solid tobacco substrate 12, and responds to a user's usage signal to control the first atomization core 112 and the second atomization core 132 to atomize.

[0048] 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 in the figure).

[0049] Among them, the first detection element is used to detect and send a heating signal of the solid tobacco substrate 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 may be generated when the heating temperature of the heating component 16 is less than a preset temperature.

[0050] The second detection element is used to detect and send a first activation signal of the first atomization source 11, and the controller 17 responds to the first activation signal and controls the first atomization source 11 to be activated, that is, controls the first atomization core 112 to heat and atomize the first aerosol generating matrix; among them, the first activation signal may specifically be a user's usage signal, for example, it may be a power-on signal, a user's suction signal, or other control signals.

[0051] The third detection element is used to detect and send a second activation signal of the second atomization source 13, and the controller 17 responds to the second activation signal and controls the second atomization source 13 to be activated, that is, controls the second atomization core 132 to heat and atomize the second aerosol generating matrix; among them, the second activation signal may be a user's suction signal, a user's touch signal, or a time signal generated after a preset time when the first atomization source 11 is activated.

[0052] Specifically, when the above activation signal is a suction signal, the detection element may be an airflow sensor, such as a microphone, to send a suction signal to the controller 17; when the activation signal is a user's touch signal, the detection element may be a touch sensor.

[0053] Of course, in other embodiments, the activation signals of the first atomization source 11 and the second atomization source 13 may also be detected and sent by the same detection element, and the activation 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.

[0054] The atomizer 10 provided in this embodiment is configured such that a first atomization source 11 is provided, and a first liquid storage cavity 111 of the first atomization source 11 stores a first aerosol-forming matrix. The first atomization core 112 of the first atomization source 11 atomizes the first aerosol-forming matrix to form a first aerosol. At the same time, a second atomization source 13 is provided, and a second liquid storage cavity 131 of the second atomization source 13 stores a second aerosol-forming matrix. The second atomization core 132 of the second atomization source 13 atomizes the second aerosol-forming matrix to form a second aerosol containing stabilizer molecules. Additionally, a solid tobacco base 12 is provided to release nicotine, and the solid tobacco base 12 is arranged on the airflow path of the first atomization source 11 and the second atomization source 13, so that the first aerosol passes through the solid tobacco base 12 and carries out nicotine, and is mixed with the second aerosol, and the nicotine binds to the stabilizer molecules to form nicotine aerosol particles with a higher stability in the core. Among them, since the stabilizer molecules bind to the released nicotine downstream of the solid tobacco base 12 to form more stable nicotine aerosol particles, it can not only reduce the irritation of nicotine to the user's throat, increase the release amount of nicotine, and the stable nicotine aerosol particles will not deposit on the surface of the solid tobacco base 12 to hinder the release of nicotine, thereby effectively increasing the release amount of nicotine and ensuring that the released nicotine can be maximally sucked by the user, and further increasing the nicotine content in the aerosol sucked by the user. Additionally, 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 part of the aerosol atomized by the atomizer 10 passes through the solid tobacco base 12. Compared with the solution where all the aerosol atomized 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, the influence of the condensate on the nicotine release amount is reduced, and further the nicotine content in the aerosol sucked by the user is effectively increased. Furthermore, a heating component 16 is provided to heat the solid tobacco base 12. And since the solid tobacco base 12 is arranged between the first atomization core 112 of the first atomization source 11 and the second atomization core 132 of the second atomization source 13, compared with the solution without the second atomization core 132, the solid tobacco base 12 is farther away from the mouthpiece 15, so that the heating temperature of the heating component 16 can be effectively increased to further increase the release amount of nicotine.

[0055] The working principle of the atomizer 10 will be described in detail below.

[0056] After the controller 17 receives the start signal of the atomizer 10, it controls the heating component 16 to start, so as to start heating the solid tobacco base 12 and release the flavor aerosol; specifically, during the heating process, the temperature of the solid tobacco base 12 gradually rises and remains at a relatively constant temperature; after the controller 17 receives the user's suction signal, it controls the first atomization core 112 and the second atomization core 132 to start respectively, so as to heat the first aerosol generation matrix through the first atomization core 112 to generate the first aerosol, and heat and atomize the second aerosol generation matrix through the second atomization core 132 to generate the second aerosol including organic acid molecules; during the specific working process, the first aerosol enters the solid tobacco base 12 from the first ventilation hole of the first cover body 122, and the first aerosol carries nicotine to reach the position of the second atomization core 132 and mixes with the second aerosol, so that the nicotine carried by the first aerosol reacts with the organic acid molecules in the second aerosol to generate new nicotine aerosol particles with higher stability than gaseous nicotine, thereby reducing the irritation of gaseous nicotine to the user's throat, locking the nicotine, ensuring that the released nicotine can be maximally sucked by the user, and then increasing the nicotine content in the aerosol sucked by the user; at the same time, after the second atomization core 132 performs secondary atomization on the first aerosol and mixes it with the second aerosol, the user sucks through the mouthpiece 15.

[0057] Please refer to Figure 5 , Figure 5 which is a flowchart of a method for generating an aerosol provided by an embodiment of the present application. In this embodiment, a method for generating an aerosol is provided, and the method specifically includes:

[0058] Step S11: Atomize the first aerosol generation matrix to form the first aerosol.

[0059] Specifically, the solubility of the first aerosol generation matrix in nicotine is greater than 10 g of nicotine / 100 g of matrix to improve the carrying capacity of the first aerosol formed by atomization for nicotine; specifically, the mass percentage of all components with a boiling point not exceeding 200 °C in the first aerosol generation matrix is greater than 50%, that is, more than 50% of all components in the first aerosol generation matrix have a boiling point not exceeding 200 °C, so as to improve the volatility of the first aerosol generation matrix while making the first aerosol generation matrix have strong volatility, facilitating atomization and carrying nicotine, reducing the components in the first aerosol generation matrix that are likely to block the solid tobacco base, thereby reducing the formation of condensate on the solid tobacco base and avoiding the influence of condensate on the release of nicotine, so as to increase the nicotine content in the aerosol sucked by the user.

[0060] In a specific embodiment, the mass percentage of one or any combination of propylene glycol, water, and ethanol in the first aerosol - generating matrix 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 enhance the nicotine - carrying capacity of the first aerosol formed by atomization by using a high proportion of propylene glycol, and by reducing the proportion of high - boiling - point and difficult - to - volatilize substances (such as glycerol) in the first aerosol - generating matrix, reducing the condensation amount of the first aerosol in the solid tobacco substrate 12, and further reducing the probability of the problem that the nicotine release amount decays with the increase in the number of puffs.

[0061] It can be understood that in a specific embodiment, the first aerosol - generating matrix specifically further includes other components with a mass percentage less than 50%, such as glycerol, flavoring agents, etc.

[0062] Specifically, step S11 can be executed by the first atomization core 112 of the first atomization source 11; among them, 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 - mentioned embodiment, and can achieve the same or similar technical effects, which will not be elaborated here.

[0063] Step S12: Atomize the second aerosol - generating matrix to form a second aerosol containing stabilizer molecules.

[0064] Among them, step S12 can be executed by the second atomization source 13. Among them, the specific structure and function of the second atomization source 13 can refer to the relevant description of the second atomization source 13 in the atomizer 10 provided in the above - mentioned embodiment, and can achieve the same or similar technical effects, which will not be elaborated here. Among them, the stabilizer molecules can be organic acid molecules.

[0065] In the specific implementation process, the volatility of the second aerosol - generating matrix is less than that of the first aerosol - generating matrix; specifically, the mass percentage of all components with a boiling point exceeding 250 °C in the second aerosol - generating matrix is greater than 50%; that is, the mass percentage of the components in the second aerosol - generating matrix exceeding 50% has a boiling point exceeding 250 °C, so as to improve the stability of the second aerosol.

[0066] Specifically, the component with a mass percentage exceeding 50% in the second aerosol - generating matrix can be glycerol; it can be understood that by increasing the proportion of high - boiling - point substances (such as 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 and form nicotine aerosol particles with higher stability than gaseous nicotine.

[0067] Of course, in a specific embodiment, the second aerosol generating matrix may also include other components with a mass percentage lower than 50%, such as a small amount of propylene glycol and an organic acid with a mass percentage of 0-10%. Specifically, the second aerosol generating matrix is composed of propylene glycol, glycerol, organic acid and flavors.

[0068] Step S13: the first aerosol is passed through the solid tobacco base to carry out nicotine released from the solid tobacco base and then mixes with the second aerosol.

[0069] In the specific implementation process, the nicotine carried by the first aerosol combines with the stabilizer molecules to form nicotine aerosol particles with higher stability than nicotine, so as to reduce the irritation of the gaseous nicotine to the throat of the user, lock the gaseous nicotine and prevent it from being lost, so as to increase the nicotine content in the aerosol inhaled by the user and enhance the user's satisfaction.

[0070] In 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, which will not be repeated here.

[0071] Among them, since this process is after the nicotine is released, it combines with the second aerosol containing organic acid molecules to form nicotine aerosol particles with higher stability than gaseous nicotine, which can not only reduce the irritation of gaseous nicotine to the throat of the user, but also lock the gaseous nicotine to prevent loss, so as to increase the nicotine content in the aerosol inhaled by the user and enhance the user's satisfaction, and the nicotine aerosol particles will not be deposited on the surface of the solid tobacco base 12, will not affect the release of nicotine, that is, will not aggravate the problem of nicotine release attenuation, thereby effectively increasing the release of nicotine.

[0072] In 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 get a better smoking experience.

[0073] The aerosol generation method provided in this embodiment forms a first aerosol by atomizing a first aerosol generation matrix and forms a second aerosol containing stabilizer molecules by atomizing a second aerosol generation matrix; then the first aerosol is passed through the solid tobacco substrate 12, and after the nicotine released from the solid tobacco substrate 12 is carried out, it is mixed with the second aerosol, so that the nicotine combines with the stabilizer molecules to form nicotine aerosol particles with higher stability than nicotine. Thus, it can not only reduce the irritation of gaseous nicotine to the user's throat, lock the gaseous nicotine to prevent loss, so as to increase the nicotine content in the aerosol inhaled by the user and enhance the user's satisfaction, and the nicotine aerosol particles will not deposit on the surface of the solid tobacco substrate 12 and will not affect the nicotine release amount, that is, it will not exacerbate the problem of nicotine release amount attenuation, so as to effectively increase the nicotine release amount; in addition, by heating the fixed tobacco substrate 12, the nicotine release amount can be effectively increased.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of this application by the same token.
