[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] In some embodiments, an aerosol generating article is provided, comprising a heating section, a cooling section, a mouthpiece section, and a plug section. The heating section is made of a smoke-generating medium capable of generating aerosols. The aerosol is cooled by the cooling section, then passes through the mouthpiece section to reach a position where it can be inhaled by the user. The plug section is a structure located at the end of the heating section furthest from the cooling section, used to fix the smoke-generating medium within the heating section. With this configuration, although the aerosol generated by the heating section can be cooled by the cooling section, the cooling effect is difficult to control, and flavor can only be provided through the smoke-generating medium of the heating section.

[0021] In some embodiments, the aerosol generating article is a product that is heated but not burned, and atomizes the aroma substances and nicotine in the smoke-generating matrix of the heating section into an aerogel for the user to inhale.

[0022] Please refer to Figure 1 and Figure 2Some embodiments of this application provide an aerosol generating apparatus 100, including a heating chamber 10 for removably receiving an aerosol generating article 200. In these embodiments, the heating chamber 10 may be formed through a housing of the aerosol generating apparatus 100. Furthermore, the heating chamber 10 has an openable and closable opening 12 through which the aerosol generating article 200 can be placed into and removed. It is understood that the heating chamber 10 provides a sealed environment for the aerosol generating article 200, allowing it to be heated and generate aerosols within this sealed environment, preventing leakage.

[0023] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0024] In some embodiments, a fixing structure for fixing the aerosol generating article 200 may be provided in the heating chamber 10 to keep the aerosol generating article 200 in the correct posture within the heating chamber 10.

[0025] In these embodiments, by improving the structure of the aerosol generating device 100, the existing form of the aerosol generating product 200 is broken through. The cooling section and nozzle section of the aerosol generating product 200 are designed into the aerosol generating device 100, while only the heating section structure of the aerosol generating product 200 is retained. This reduces the material loss of the cooling section and nozzle section, improves the production economic efficiency of the aerosol generating product 200, and at the same time gives the structural form of the aerosol generating product 200 more adjustable space.

[0026] In some embodiments, please refer to Figure 2 The aerosol generating apparatus 100 also includes a heater for heating the aerosol generating article 200 received in the heating chamber 10 to generate an aerosol.

[0027] In some embodiments, a heater may be disposed around the heating chamber 10, and the heater may raise the gas temperature in the heating chamber 10 by heating, so that the aerosol generating article 200 is heated to generate aerosol.

[0028] In some embodiments, the heater may be disposed inside the heating chamber 10, and the heater may be directly inserted into the aerosol generating article 200 to directly heat the aerosol generating article 200.

[0029] In some embodiments, the heating chamber 10 is configured to circumferentially heat the aerosol-generating article 200. In some embodiments, the heater includes a heating mesh that may be arranged circumferentially around the heating chamber 10 to achieve circumferential heating of the aerosol-generating article 200. In some embodiments, the heater includes a heating wire that may also be arranged circumferentially around the heating chamber 10 to achieve circumferential heating of the aerosol-generating article 200.

[0030] In some embodiments, please refer to Figure 2 The aerosol generating apparatus 100 also includes a medium chamber 20, which stores a liquid medium 40. In these embodiments, storing the liquid medium 40 in the medium chamber 20 can enrich the user experience; for example, the liquid medium 40 containing flavoring substances can be used to enrich the flavor of the aerosol. Furthermore, the liquid medium 40 itself can absorb heat, which can be used to cool the aerosol, improving the temperature at the nozzle 60 where the aerosol generating matrix reaches. This also improves the safety of using the aerosol generating matrix.

[0031] In some embodiments, please refer to Figure 2 The aerosol generating apparatus 100 also includes a vent pipe 30, one end of which is connected to the heating chamber 10, and the other end of which is placed in or below the surface of the liquid medium 40. In these embodiments, the heating chamber 10 is connected to the medium chamber 20 via the vent pipe 30, allowing the aerosol to enter the heating chamber 10 through the vent pipe 30. The other end of the vent pipe 30 being placed in or below the surface of the liquid medium 40 allows the aerosol to come into contact with the liquid medium 40, thereby achieving a cooling effect on the aerosol. With this configuration, the aerosol can be cooled within the medium chamber 20, eliminating the need for a cooling section structure on the aerosol generating article 200.

[0032] For example, the liquid medium 40 can be a pure aqueous solution, in which case the liquid medium 40 can achieve a cooling effect on the aerosol.

[0033] As another example, the liquid medium 40 can be an aqueous solution with added flavoring substances. In this configuration, the liquid medium 40 can not only cool the aerosol, but also add the flavor of the liquid medium 40 to the aerosol, thereby improving the user experience.

[0034] In some embodiments, please refer to Figure 2The aerosol generating device 100 also includes an outlet pipe 50. One end of the outlet pipe 50 is connected to the suction nozzle 60 of the aerosol generating device 100, and the other end of the outlet pipe 50 is positioned close to or above the liquid surface of the liquid medium 40. In these embodiments, the cooled aerosol can reach the suction nozzle 60 through the outlet pipe 50 and be inhaled by the user. Positioning the other end of the outlet pipe 50 close to or above the liquid surface of the liquid medium 40 facilitates faster and more efficient delivery of the aerosol to the suction nozzle 60.

[0035] In some embodiments, the liquid medium 40 is a pure aqueous solution, or the liquid medium 40 is a solution with added flavoring substances.

[0036] In some embodiments, please refer to Figure 2 A waterproof and breathable membrane 70 is provided at the other end of the vent pipe 30 and / or the other end of the outlet pipe 50. The end of the vent pipe 30 or outlet pipe 50 that connects to the medium chamber 20 may be provided with the waterproof and breathable membrane 70. The function of the waterproof and breathable membrane 70 is to allow gas to pass through the membrane layer while preventing liquid from passing through, thereby achieving the effect of being breathable but not waterproof. With this configuration, the air pressure in the medium chamber 20 can be maintained in a balanced state, helping the aerosol to pass normally through the outlet pipe 50 to the nozzle 60, and preventing liquid medium 40 from entering the vent pipe 30 or outlet pipe 50 and contaminating the internal environment, thus affecting the taste of the aerosol.

[0037] In some embodiments, please refer to Figure 2 The heating chamber 10 has an air outlet 11, which is connected to one end of the vent pipe 30. An isolation net is provided at the air outlet 11. In these embodiments, when debris or other impurities fall from the aerosol generating product 200 during the heating process, the isolation net can prevent the impurities from entering the medium chamber 20 through the vent pipe 30 and contaminating the liquid medium 40.

[0038] Please refer to Figure 2 In some embodiments, the heating chamber 10 also has an opening 12 through which the aerosol-generating article 200 is removably received. The opening 12 is provided with an openable and closable cap 13. In these embodiments, the opening 12 allows for the addition, removal, and replacement of the aerosol-generating article 200 within the heating chamber 10. The cap 13 ensures the airtightness of the heating chamber 10 during the heating process.

[0039] In some embodiments, the cover 13 can be pivoted to open and close the opening 12. In some embodiments, the cover 13 can also be snap-fitted to open and close the opening 12. In some embodiments, the cover 13 can also be adhesively pasted to open and close the opening 12.

[0040] Please refer to Figure 2 In some embodiments, a smoke removal mechanism 80 is also included, which is operable to remove at least partially the aerosol-generating article 200 from the heating chamber 10. In these embodiments, it is understood that without the smoke removal mechanism 80, if the aerosol-generating article 200 needs to be removed directly from the heating chamber 10, the user would need to face the opening 12 of the heating chamber 10 towards the ground to easily pour out the aerosol-generating article 200. This makes removing the aerosol-generating article 200 difficult; therefore, the smoke removal mechanism 80 assists in removing the aerosol-generating article 200.

[0041] In some embodiments, please refer to Figure 2 The smoke-removing mechanism 80 includes a handle 81 disposed on the housing of the aerosol generating device 100. The handle 81 is configured to allow at least a portion of the heating chamber 10 to disengage from the interior of the housing through the opening 12. Exemplarily, the housing structure of the heating chamber 10 is movably disposed within the housing of the aerosol generating device 100. One end of the handle 81 passes through the housing and connects to the housing structure of the heating chamber 10, while the other end remains outside the housing. The user can move the handle 81 to move the housing structure of the heating chamber 10 toward the opening 12, thereby disengaging at least a portion of it from the interior of the housing through the opening 12.

[0042] In some embodiments, please refer to Figure 2 It also includes a reset member 82, one end of which is connected to the housing structure of the heating chamber 10, and the other end of which is connected to the handle 81. The reset member 82 is configured to reset the housing structure of the heating chamber 10 that has detached from the interior of the housing. In these embodiments, the reset member 82 helps the user to automatically reset the heating chamber 10 back into the interior of the housing after using the handle 81.

[0043] Please refer to Figure 1 and Figure 2 In some embodiments, the housing of the aerosol generating device 100 includes a first housing 101 and a second housing 102 detachably connected to the first housing 101. The first housing 101 and the second housing 102 may be connected by a snap-fit ​​1001 or by threads.

[0044] In some embodiments, the heating chamber 10 and the heater are disposed within the first housing 101, and the medium chamber 20 is formed within the second housing 102. In these embodiments, the heating chamber 10 and the medium chamber 20 are disposed independently to facilitate the production and assembly of the aerosol generating device 100. In some applications, the first housing 101 and the second housing 102 can be stored and transported separately at the factory, and then assembled for use by the user. In some applications, after the aerosol generating device 100 has been used, the second housing 102 can be replaced as needed to allow for the use of different flavored liquid media 40.

[0045] In some embodiments, the second housing 102 is at least partially made of a transparent material so that the liquid medium 40 can be observed. For example, an observation area may be provided on the second housing 102, the observation area being made of a transparent material, so that the condition of the liquid medium 40 can be observed through this observation area. As another example, the second housing 102 may be made of a transparent material so that the condition of the liquid medium 40 can be observed from any direction of the second housing 102.

[0046] In some embodiments, please refer to Figure 2 The housing of the aerosol generating device 100 is provided with a liquid filling port 103 and a liquid discharge port 104 communicating with the medium chamber 20. In these embodiments, aerosol is injected into the medium chamber 20 through the liquid filling port 103 and discharged through the liquid discharge port 104.

[0047] In some embodiments, please refer to Figure 2 One end of the vent pipe 30 extends into the medium chamber 20 through the liquid filling port 103.

[0048] In some embodiments, please refer to Figure 2 One end of the vent pipe 50 extends into the medium chamber 20 through the liquid discharge port 104.

[0049] In some embodiments, please refer to Figure 2 The liquid filling port 103 and the liquid unloading port 104 are provided on the second housing 102.

[0050] In some embodiments, please refer to Figure 2The aerosol generating device 100 also includes a control mechanism 90, which includes a temperature control component 91, a power supply 92, and a main control component 93. The main control component 93 is electrically connected to both the temperature control component 91 and the power supply 92. The temperature control component 91 is electrically connected to both the heating chamber 10 and the power supply 92. In these embodiments, the power supply 92 supplies power to the heating chamber 10 and to the temperature control component 91 and the main control component 93. The main control component 93 can control the operation of the temperature control component 91, as well as the start / stop and heating timing of the heating chamber 10. The temperature control component 91 can set and adjust the temperature of the heating chamber 10.

[0051] In some embodiments, please refer to Figure 2 The aerosol generating device 100 also includes a charging port 105, which is connected to a power supply 92, and the power supply 92 charges through the charging port 105.

[0052] In some embodiments, please refer to Figure 2 The charging port 105 is located on the first housing 101.

[0053] In these embodiments, the aerosol generating device 100 of this application is used in conjunction with the aerosol generating product 200 provided in this application. Compared with existing aerosol generating products 200, the structure is simpler, retaining only the heating section, thus increasing the diversity of the aerosol generating product 200's form. This improvement in the structure of the aerosol generating product 200 saves material in the cooling section and the suction end filter rod, reducing production costs and improving economic efficiency. In these embodiments, the cooling section and suction section of the aerosol generating product 200 are designed into the body of the aerosol generating device 100, indirectly reducing the loss of material in the cooling section and suction section of the aerosol generating product 200 structure, thereby improving the economic efficiency of the aerosol generating product 200.

[0054] In these embodiments, the medium chamber 20 allows the addition of an aqueous solution of flavoring substances. During inhalation, the solution is washed away by the aerosol, which can compensate for the aroma and enhance the richness of the aerosol's aroma. The transparent shell design and the gurgling sound during inhalation provide users with the experience of using an atomizing device, increasing the fun of inhalation and improving the overall experience.

[0055] Some embodiments of this application also provide an aerosol generation system, including an aerosol generation article 200 and an aerosol generation device 100 in any of the above embodiments.
