Specifically, referring to fig. 3, fig. 3 is a schematic structural diagram of a flavor capsule provided in an embodiment of the present application; the flavor capsule 120 may include a body 121, a first cover 122, and a second cover 123.

Wherein, the projectile body 121 may be a columnar structure; the projectile body 121 is formed with an accommodating cavity having a first cavity opening and a second cavity opening; in one embodiment, the projectile 121 may be made of paper; the solid tobacco base 12 is stored in the containing cavity and used for releasing and regulating aerosol; the first cover body 122 is covered on the first cavity opening, and a plurality of first air holes are formed in the first cover body 122, so that the first aerosol enters the accommodating cavity through the first air holes; the second cover body 123 covers the second cavity, and a plurality of second air holes are formed in the second cover body 123, so that the first aerosol carrying nicotine flows out of the accommodating cavity through the second air holes; specifically, the material of the first cap 122 and/or the second cap 123 may be metal, and the adjusting matrix may be a flavoring substance, such as tobacco particles; the plurality of first air holes can be uniformly distributed on the first cover body 122, so that the first aerosol can be better mixed with nicotine released by the solid tobacco base 12, the mixing uniformity is improved, and the smoking taste of a user is enhanced; the second ventilation holes may also be uniformly distributed on the second cover 123, which is not limited in this embodiment.

The atomizer 10 provided by the present embodiment is provided, the atomizer 10 is provided with a first liquid storage cavity 111, a first atomizing core 112 and a solid cigarette base 12; wherein, the first aerosol-generating substrate is stored in the first liquid storage cavity 111, the first atomizing core 112 is used for atomizing the first aerosol-generating substrate to form a first aerosol, and the solid tobacco substrate 12 is used for releasing nicotine; the mass percentage of all components with the boiling point not more than 200 ℃ in the first aerosol generating substrate is more than 50 percent, so that the volatility of the first aerosol generating substrate is improved, the components which are easy to block the solid smoke base 12 in the first aerosol generating substrate are reduced, and the formation of condensate on the solid smoke base 12 is reduced; in addition, by providing the air flow channel 14a, the air flow channel 14a includes an air outlet, and the first atomizing core 112 and the solid tobacco base 12 are located in the air flow channel 14a, and the solid tobacco base 12 is located between the first atomizing core 112 and the air outlet, so that the first aerosol passes through the solid tobacco base 12 and carries away the nicotine released from the solid tobacco base 12.

In an embodiment, referring to fig. 2b to 4, the nebulizer 10 further comprises a second nebulization source 13, the second nebulization source 13 storing a second aerosol-generating substrate for nebulizing the second aerosol-generating substrate to form a second aerosol comprising 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, and the first aerosol entrains nicotine and mixes with the second aerosol atomized by the second atomization source 13 to combine the nicotine and the stabilizer molecules to form new nicotine aerosol particles; meanwhile, the first aerosol is heated and atomized for the second time through the second atomization source 13, so that the atomization amount is increased, and the smoking taste of a user is enhanced; wherein the stability of the new nicotine aerosol particles is higher compared to the stability of gaseous nicotine.

Wherein the stabilizer molecule can be specifically an organic acid molecule; the first and second aerosol-generating substrates may contain nicotine or no nicotine component, in a preferred embodiment neither the first nor the second aerosol-generating substrate contains nicotine or only a small amount of nicotine.

To improve the stability of the generated second aerosol-generating substrate to react well with nicotine, the second aerosol-generating substrate has a volatility less than the volatility of the first aerosol-generating substrate; in particular, the second aerosol-generating substrate has a mass percentage of all components with a boiling point above 250 ℃ of greater than 50%; that is, more than 50% by mass of the components in the second aerosol-generating substrate have a boiling point in excess of 250 ℃.

In particular, the component of the second aerosol-generating substrate in an amount of more than 50% by mass may be glycerol to absorb more of the gaseous nicotine by increasing the proportion of the high boiling substance (glycerol) in the second aerosol-generating substrate 13, so that the stabilizer molecules, i.e. the organic acid molecules, in the second aerosol react with the nicotine and form nicotine aerosol particles which are more stable than the gaseous nicotine, thereby reducing the irritation of the gaseous nicotine to the throat of the user and locking the gaseous nicotine to prevent loss, to increase the content of nicotine in the aerosol drawn by the user and to enhance the satisfaction of the user.

Because the second atomization source 13 is located downstream of the solid tobacco base 12, that is, after the nicotine is released, the organic acid is added to form new nicotine aerosol particles with higher stability than the gaseous nicotine, compared with the gaseous nicotine, the irritation of the nicotine to the throat of the user can be reduced, and the released nicotine can be locked, so that the release amount of the nicotine can be ensured, the experience effect of the user can be enhanced, and the nicotine salt can not be deposited in the flavor capsule 120, so that the release amount of the nicotine in the solid tobacco base 12 in the flavor capsule 120 can not be affected, that is, the problem of nicotine release amount attenuation can not be aggravated.

In particular embodiments, the boiling point of each component in the first aerosol-generating substrate does not exceed 200 ℃ and the boiling point of at least one component in the second aerosol-generating substrate exceeds 250 ℃.

Of course, in particular embodiments, other components may be included in the second aerosol-generating substrate in amounts less than 50% by mass, such as small amounts of propylene glycol and 0-10% by mass of organic acids. In particular, the second aerosol-generating substrate may specifically consist of propylene glycol, glycerol, an organic acid and a fragrance perfume.

Specifically, the second atomization source 13 specifically includes a second reservoir 131 and a second atomization core 132.

A second aerosol-generating substrate is in particular stored in a second reservoir 131, and a second atomising core 132 is in communication with the second reservoir 131 for atomising a second aerosol-generating substrate arriving on the second atomising core 132 from the second reservoir 131 to form a second aerosol comprising stabiliser molecules; in a specific embodiment, the second liquid storage cavity 131 is located in the accommodating cavity 14 b; the second atomizing 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 will be appreciated that, in this case, the second atomizing core 132 is located at a position downstream of the solid tobacco base 12, so as to effectively avoid the influence of the 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 effectively increasing the content of nicotine in the aerosol sucked by the user.

In particular, the second atomising core 132 comprises a second porous substrate and a second heating element, the second porous substrate being in communication with the second reservoir 131 for channelling the second aerosol-generating substrate, i.e. channelling the second aerosol-generating substrate within the second reservoir 131 onto the second porous substrate; the second heating element is for heating and atomising the second aerosol-generating substrate on the second porous substrate when energised. Wherein the second porous substrate may be porous ceramic, and the second heating element may be a heat generating film disposed on the second porous substrate.

Specifically, the first aerosol formed by the first atomization source 11 carries nicotine and then reaches the second atomization core 132, the second atomization core 132 performs secondary atomization and aerosol rectification on the first aerosol carrying nicotine, and the first aerosol and the generated second aerosol containing organic acid molecules are fully mixed to form new nicotine aerosol particles with higher stability than gaseous nicotine.

In one embodiment, referring to fig. 4, fig. 4 is a schematic structural diagram of an atomizer provided in another embodiment of the present application; the atomizer 10 further includes a heating assembly 16; the heating component 16 may be specifically disposed in the airflow channel 14a and surrounds the solid tobacco base 12, and is used for heating the solid tobacco base 12 when being electrified, so as to improve the nicotine release of the solid tobacco base 12; wherein, because solid-state cigarette base 12 sets up the upper reaches at second atomizing core 132, the position of keeping away from suction nozzle 15 promptly, the first aerosol that first atomizing core 11 atomizing formed, it still need can get into suction nozzle 15 through second atomizing core 132 and be smoked by the user after carrying nicotine, compare in first aerosol directly with suction nozzle 15 intercommunication after carrying nicotine, so that the scheme of direct smoking of user, this atomizer 10 is guaranteeing under the comparatively suitable prerequisite of the temperature of the aerosol that the user smoked, can further improve the temperature that generates heat of heating element 16, in order to improve the temperature in solid-state cigarette base 12, thereby further improve the release amount of nicotine and/or the release amount of other compositions in the taste capsule 120, and then obtain better suction experience.

It can be understood that if the suction nozzle 15 sucks the solid tobacco base 12 directly, the heating temperature of the heating assembly 16 to the solid tobacco base 12 cannot be kept high, which may cause the problem that the heating assembly 16 burns the mouth at a high temperature; by disposing the solid tobacco base 12 between the first atomizing core 112 and the second atomizing core 132, the atomizer 10 of the present application can make the heating of the heating element 16 higher, so as to heat the solid tobacco base 12 to a higher temperature, thereby improving the release efficiency of nicotine and flavor.

In particular embodiments, the heating assembly 16 may be annular in shape, which may be disposed around the outside of the flavor capsule 120 and around the circumference thereof to improve the uniformity of heating of the solid tobacco base 12 within the flavor capsule 120; in one embodiment, the inner and outer sidewalls of the heating assembly 16 abut against the outer sidewall of the flavor capsule 120 and the inner sidewall of the airflow channel 14a, respectively, to avoid the first aerosol from entering the position of the second atomizing core 132 from the gap between the heating assembly 16 and the flavor capsule 120 and/or from the gap between the heating assembly 16 and the airflow channel 14a, thereby ensuring that the first aerosol can be mixed with the conditioning aerosol to ensure the mouth feeling of the user.

Of course, in particular embodiments, the temperature of the first aerosol may also be used directly to heat the solid tobacco base 12 to facilitate the release of nicotine.

In a specific embodiment, the atomizer 10 further includes a controller 17, which is responsive to the heating signal to control the heating assembly 16 to heat the solid tobacco base 12, and is responsive to the user's usage signal to control the first atomizing core 112 and the second atomizing core 132 to atomize.

Specifically, in one embodiment, the nebulizer 10 can further include a first detection element, a second detection element, and a third detection element (not shown).

The first detection element is used for detecting and sending a heating signal of the solid smoke base 12; the controller 17 responds to the heating signal and controls the heating power of the heating assembly 16; in particular embodiments, the heating signal may be generated when the heating temperature of the heating assembly 16 is less than a preset temperature.

The second detecting element is used for detecting and sending a first starting signal of the first atomizing source 11, and the controller 17 responds to the first starting signal and controls the first atomizing source 11 to be started, namely controls the first atomizing core 112 to heat and atomize the first aerosol-generating substrate; the first turn-on signal may be a user use signal, for example, a power-on signal, a user suction signal, or other control signals.

The third detection element is adapted to detect and send a second activation signal of the second atomization source 13, and the controller 17 is adapted to respond to the second activation signal and control the second atomization source 13 to activate, i.e. control the second atomization wick 132 to heat and atomize the second aerosol-generating substrate; the second turn-on signal may be a suction signal of the user, a touch signal of the user, or a time signal generated after the first atomization source 11 is turned on for a preset time.

Specifically, when the above-mentioned opening signal is a suction signal, the detecting element may be an airflow sensor, such as a microphone, for sending the suction signal to the controller 17; when the turn-on signal is a user touch signal, the detecting element may be a touch sensor.

Of course, in other embodiments, the same detection element may also be used to detect and send the on signals of the first atomization source 11 and the second atomization source 13, and the on signals may be the usage signals of the user, that is, when the usage signals of the user are detected, the detection element sends the usage signals of the user, and the controller 17 responds to the usage signals of the user to control the first atomization core 112 and the second atomization core 132 to heat and atomize.

The atomizer 10 according to the present embodiment is further provided with a second atomization source 13, and a second atomization core 123 of the second atomization source 13 is arranged in the airflow channel 14a and between the solid tobacco base 12 and the air outlet, so as to atomize the second aerosol-generating substrate through the second atomization core 132 to form a second aerosol containing stabilizer molecules; simultaneously, with the fixed tobacco base 12 positioned between the first atomizing core 112 and the second atomizing core 122, the first aerosol passes through the solid tobacco base 12 and entrains nicotine and mixes with the second aerosol to combine the nicotine with the stabilizer molecules to form new nicotine aerosol particles; wherein, because the stabilizer molecules are combined with the released nicotine at the downstream of the solid tobacco base 12 to form new nicotine aerosol particles, the irritation of the nicotine to the throat of a user can be reduced, and the stable nicotine aerosol particles can not be deposited on the surface of the solid tobacco base 12 to obstruct the release of the nicotine, so that the release amount of the nicotine can be effectively improved, and the released nicotine can be ensured to be maximally sucked by the user to improve the content of the nicotine in the aerosol sucked by the user; in addition, because only the first aerosol in the first aerosol and the second aerosol generated by the atomizer 10 passes through the solid smoke base 12, that is, only part of the aerosol formed by atomization of the atomizer 10 passes through the solid smoke base 12, compared with a scheme that all the aerosols formed by atomization of the atomizer 10 need to pass through the solid smoke base 12, the condensation amount of the aerosol in the solid smoke base 12 is effectively reduced, the influence of the condensate on the release amount of nicotine is reduced, and the release amount of nicotine is further effectively ensured; meanwhile, the heating component 16 is arranged to heat the solid tobacco base 12; and because the solid state cigarette base 12 is arranged between the first atomization core 112 and the second atomization core 132, compared with the scheme without the second atomization core 132, the solid state cigarette base 12 is far away from the suction nozzle 15, so that the heating temperature of the heating assembly 16 can be effectively increased, and the release amount of the regulation aerosol containing nicotine is further increased.

The operating principle of the atomizer 10 is described in detail below.

After receiving the starting signal of the atomizer 10, the controller 17 controls the heating component 16 to be started so as to heat the solid tobacco base 12 and release the dispensing 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 puff signal, the controller 17 controls the first atomizing wick 112 and the second atomizing wick 132 to be turned on, respectively, to heat the first aerosol-generating substrate by the first atomizing wick 112 to generate a first aerosol, and to heat and atomize the second aerosol-generating substrate by the second atomizing wick 132 to generate a second aerosol comprising organic acid molecules; in a specific working process, the first aerosol enters the solid tobacco base 12 from the first air holes of the first cover body 122, and the first aerosol carries nicotine to reach the position of the second atomizing core 132 and is mixed with the second aerosol, so that the nicotine carried by the first aerosol reacts with organic acid molecules in the second aerosol to generate new nicotine aerosol particles with higher stability than gaseous nicotine, and further the irritation of the gaseous nicotine to the throat of a user is reduced, the nicotine is locked, and the released nicotine can be maximally sucked by the user; after the first aerosol is atomized again and mixed with the second aerosol by the second atomizing core 132, the user sucks the aerosol through the suction nozzle 15.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for generating an aerosol according to an embodiment of the present disclosure. In this embodiment, a method for generating an aerosol is provided, which specifically includes:

step S11: atomizing the first aerosol-generating substrate to form a first aerosol.

Specifically, the mass percentage of all components with boiling points not higher than 200 ℃ in the first aerosol-generating substrate is more than 50%, that is, the boiling points of more than 50% of all components in the first aerosol-generating substrate are not higher than 200 ℃, so that the volatility of the first aerosol-generating substrate is improved, the first aerosol-generating substrate has stronger volatility, the atomization is facilitated, nicotine is carried, meanwhile, the components which are easy to block a solid tobacco base in the first aerosol-generating substrate are reduced, the formation of condensate on the solid tobacco base is further reduced, the influence of the condensate on the release of nicotine is avoided, and the release amount of nicotine is improved.

In particular, the first aerosol-generating substrate has a solubility for nicotine of greater than 10g nicotine/100 g substrate to enhance the nicotine carrying capacity of the first aerosol formed by atomization.

In a specific embodiment, the first aerosol-generating substrate comprises one or any combination of propylene glycol, water and ethanol, and the mass percentage of the 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 substrate are one or any combination of propylene glycol, water and ethanol; specifically, more than 50% of the components in the first aerosol-generating substrate can be propylene glycol, so that the nicotine carrying capacity of the atomized first aerosol is enhanced by using a high proportion of propylene glycol, the condensation amount of the first aerosol in the solid tobacco base 12 is reduced by reducing the proportion of high-boiling point and nonvolatile substances (namely glycerol) in the first aerosol-generating substrate, and the occurrence probability of the problem that the nicotine release amount is reduced along with the increase of the smoking times is further reduced.

It will be appreciated that in particular embodiments, the first aerosol-generating substrate may also comprise in particular less than 50% by weight of other components, such as glycerol and perfume flavours and the like.

Specifically, step S11 may be performed by the first atomizing core 112 of the first atomizing source 11; the specific structure and function of the first atomization source 11 can be referred to in the description related to 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 is not described herein again.

Step S12: passing the first aerosol through the solid tobacco base and entraining the nicotine released from the solid tobacco base.

In the specific implementation process, the method can also comprise the steps of heating the solid tobacco base 12 and releasing nicotine, so that the release amount of nicotine can be further improved; for a specific working principle, reference may be made to the above description of related texts, which are not repeated herein.

In the aerosol generating method provided by this embodiment, the first aerosol generating substrate is atomized to form the first aerosol, and the mass percentage of all components in the first aerosol generating substrate with a boiling point of not more than 200 ℃ is greater than 50%, so as to increase the volatility of the first aerosol generating substrate, reduce the components in the first aerosol generating substrate that are easy to block the solid tobacco base 12, and further reduce the formation of condensate on the solid tobacco base 12; simultaneously, nicotine released by passing the first aerosol through the solid tobacco base 12 and carrying the solid tobacco base 12 away for inhalation by the user; in addition, the release amount of nicotine can be effectively increased by heating the fixed tobacco base 12.

In one implementation, the aerosol generating method may further include: atomizing the second aerosol-generating substrate to form a second aerosol comprising stabilizer molecules. Specifically, this step may be performed by the second atomizing core 132 of the second atomizing source 13, wherein the specific structure and function of the second atomizing source 13 can be referred to the related description about the second atomizing source 13 in the atomizer 10 provided in the above embodiment, and the same or similar technical effects can be achieved, which is not repeated herein. Wherein the stabilizer molecule may be an organic acid molecule.

In particular implementations, the volatility of the second aerosol-generating substrate is less than the volatility of the first aerosol-generating substrate; in particular, the second aerosol-generating substrate has a mass percentage of all components with a boiling point above 250 ℃ of greater than 50%; i.e. more than 50% by mass of the components in the second aerosol-generating substrate have a boiling point in excess of 250 c to improve the stability of the second aerosol for better reaction with nicotine.

In particular, more than 50% by mass of the second aerosol-generating substrate may be glycerol; it will be appreciated that by increasing the proportion of high boiling point material (e.g. glycerol) in the second aerosol-generating substrate, the second aerosol comprising organic acid molecules formed by atomising the second aerosol-generating substrate is able to absorb more of the gaseous nicotine so that the organic acid molecules react with the nicotine and form new nicotine aerosol particles which are more stable than the gaseous nicotine.

Of course, in particular embodiments, other components may be included in the second aerosol-generating substrate in amounts below 50% by weight, such as small amounts of propylene glycol and 0-10% by weight of organic acids. In particular, the second aerosol-generating substrate consists in particular of propylene glycol, glycerol, an organic acid and an aroma fragrance.

Specifically, in an embodiment, after step S12, the method further comprises mixing with the second aerosol to combine nicotine and the stabilizer molecules to form new nicotine aerosol particles with higher stability than nicotine, that is, the first aerosol carries nicotine and the second aerosol are mixed to combine nicotine and the stabilizer molecules to form new nicotine aerosol particles with higher stability than nicotine.

Specifically, the nicotine carried by the first aerosol is combined with the stabilizer molecules to form new nicotine aerosol particles with higher stability than nicotine, so that the irritation of gaseous nicotine to the throat of a user is reduced, the gaseous nicotine is locked, the loss is prevented, the nicotine amount sucked by the user is increased, and the satisfaction of the user is enhanced.

After the nicotine is released, the nicotine is combined with a second aerosol containing organic acid molecules to form new nicotine aerosol particles with higher stability than gaseous nicotine, so that the irritation of the gaseous nicotine to the throat of a user can be reduced, the gaseous nicotine is locked, loss is prevented, the nicotine amount sucked by the user is increased, the satisfaction of the user is enhanced, the nicotine aerosol particles cannot be deposited on the surface of the solid tobacco base 12, the nicotine release amount is not influenced, namely, the problem of nicotine release amount attenuation is not aggravated, and the nicotine content in the aerosol sucked by the user can be effectively increased.

In a specific implementation process, the second atomizing core 132 of the second atomizing source 13 may be further used to perform secondary atomization on the nicotine-carrying first aerosol; specifically, the nicotine-carrying first aerosol is further atomized by the second heating element in the second atomization source 13, so as to improve the atomization amount and enable the user to obtain a better smoking experience.

The present embodiment provides a method of generating an aerosol by further atomising a second aerosol-generating substrate to form a second aerosol comprising stabiliser molecules; and then the first aerosol passes through the solid tobacco base 12 and carries the nicotine released from the solid tobacco base 12, and then the first aerosol is mixed with the second aerosol, so that the nicotine is combined with the stabilizer molecules to form new nicotine aerosol particles with higher stability than the nicotine, thereby not only reducing the stimulation of the gaseous nicotine to the throat of a user, but also locking the gaseous nicotine and preventing loss, so as to improve the content of the nicotine in the aerosol sucked by the user and enhance the satisfaction of the user, and the nicotine aerosol particles can not be deposited on the surface of the solid tobacco base 12, and can not influence the release amount of the nicotine, namely, the problem of nicotine release amount attenuation is not aggravated, and the release amount of the nicotine can be effectively improved.
