Fig. 1-2 illustrate an aerosol-generating system 100 in some embodiments of the invention, which aerosol-generating system 100 may comprise an aerosol-generating article 10 and an aerosol-generating device 20 for receiving and heating the aerosol-generating article 10. The aerosol-generating article 10 is removably inserted into the aerosol-generating device 20 to facilitate removal and replacement of a new aerosol-generating article 10 for further use after heating has been completed. The aerosol-generating device 20 may bake and heat the aerosol-generating article 10 inserted therein at a low temperature after being energized, to release the aerosol extract in the aerosol-generating article 10 in a non-combustible state. The aerosol-generating device 20 may be generally square cylindrical and the aerosol-generating article 10 cylindrical. It is understood that in other embodiments, the aerosol generating device 20 is not limited to a square cylinder, but may have other shapes such as a cylinder, an elliptic cylinder, and the like. The aerosol-generating article 10 is not limited to a cylindrical shape, and may have other shapes such as an elliptical columnar shape and a square columnar shape.

The aerosol-generating device 20 may include a case 21, a battery 22, a heating body 23, a container 24, and a circuit board 25. The battery 22, the heating element 23, the container 24, and the circuit board 25 are accommodated in the case 21. The receptacle 24 is tubular with an inner wall defining a receiving cavity 240 for receiving the aerosol-generating article 10. The top of the outer shell 21 is provided with a plug-in opening 210, through which the aerosol-generating article 10 can be inserted into the receiving cavity 240. The heating element 23 may be in the form of a sheet, a rod, or other shapes, the upper end of the heating element 23 may be inserted into the accommodating cavity 240 and the aerosol-generating product 10, and the heating element 23 may transmit heat to the aerosol-generating product 10 after being heated by being energized, thereby implementing the baking and heating of the aerosol-generating product 10. The battery 22 is electrically connected to the heating element 23 and the circuit board 25, respectively, for supplying power to the heating element 23 and the circuit board 25. The circuit board 25 is used for arranging the relevant control circuit.

It will be appreciated that in other embodiments, the heat-generating body 23 may also be tubular and the aerosol-generating article 10 may be inserted into the tubular heat-generating body 23 for heating. At this time, the receiver 24 may not be provided in the housing 21.

In some embodiments, the aerosol-generating device 20 may further include a mounting base 26 disposed in the housing 21. The lower end of the heating element 23 can be inserted into the fixed seat 26, and the heating element 23 can be installed and fixed in the shell 21. Further, the aerosol generating device 20 may also include a dust cap 27 for covering or uncovering the receptacle 210. When the aerosol generating device 20 is not required to be used, the dust cap 27 can be pushed to shield the socket 210, so as to prevent dust from entering the socket 210. When required for use, the dust cap 27 is pushed to expose the socket 210 so that the aerosol-generating article 10 is inserted from the socket 210.

As shown in fig. 3-4, the aerosol-generating article 10 comprises an outer wrapper 11, a heat-conducting sleeve 12, an atomizing medium section 13, a cooling section 14 and a mouthpiece section 15. The segment of atomizing medium 13 is at least partially received in the heat conducting sleeve 12, and the segment of atomizing medium 13, the cooling segment 14, and the suction nozzle segment 15 are sequentially arranged along the axial direction of the aerosol-generating article 10.

The aerosol-generating article 10 in this embodiment is a three-part structure. The segment of atomizing medium 13 may include one or more of a solid smoking substrate in the form of a thread, a sheet, a granule, a powder, a paste, etc., which is capable of releasing the aerosol extract therein when heated. The cooling section 14 is used for cooling the aerosol generated by the atomizing medium section 13, and further outputting the aerosol to the suction nozzle section 15, so as to ensure that the aerosol output by the suction nozzle section 15 reaches a proper temperature, for example, below 50 ℃. When the aerosol-generating article 10 is inserted into the aerosol-generating device 20, the nozzle segment 15 may be at least partially exposed outside the socket 210 for use by a smoker for smoking; the atomizing medium section 13 is in contact with the heating element 23, and the heating element 23 transfers heat to the atomizing medium section 13 after being electrified and heated so as to release the aerosol extract in the atomizing medium section 13.

It will be appreciated that the aerosol-generating article 10 is not limited to the three-piece construction described above. For example, a filtering section can be arranged between the cooling section 14 and the suction nozzle section 15 for filtering the flue gas, so as to achieve the gain effect of improving the purity of the flue gas. As another example, the aerosol-generating article 10 may also be provided without the cooling section 14 and/or the mouthpiece section 15, the smoke may be cooled by providing additional cooling structure in the aerosol-generating device 20, and/or additional mouthpiece structure on top of the aerosol-generating device 20 for use by a smoker.

In this embodiment, the outer covering 11 is tubular and surrounds the atomizing medium section 13, the cooling section 14 and the nozzle section 15. The material of the outer wrapper 11 may comprise one or more of a paper sheet, a paper tube, a foil sheet, a foil tube. In other embodiments, the outer cover 11 may not cover the atomizing medium section 13, but the heat-conducting sleeve 12 may enclose the atomizing medium section 13.

The heat conductive sleeve 12 may include a tubular side wall 121 and an end wall 122 disposed at an end of the tubular side wall 121 remote from the nozzle segment 15. In this embodiment, the end wall 122 covers the bottom end of the tubular side wall 121, and the heat conducting sleeve 12 covers the bottom surface and at least part of the side surface of the atomizing medium section 13. The heat conduction sleeve 12 has a large heat conduction coefficient, can reduce the thermal resistance from the bottom to the side of the atomized medium section 13, enables the heat at the bottom of the atomized medium section 13 to be recycled to the side of the atomized medium section 13, realizes the directional recycling of energy, improves the heat utilization rate, enables the atomized medium section 13 to be heated more uniformly, and has better aerosol suction experience. In addition, the heat transferred to the outside by the atomized medium section 13 can be reduced, the heat is reduced to be transferred to the bottom of the container 24 and the fixed seat 26, and the fixed seat 26 is prevented from being damaged.

The thermally conductive jacket 12 may be formed from a high thermal conductivity material, such as one or more of tin foil, copper foil, and the like. The thermally conductive sleeve 12 may directly or indirectly encase the segment of atomizing medium 13. In particular, in this embodiment, the heat-conducting sleeve 12 directly surrounds the segment of aerosol-generating article 13, and the outer coating 11 further surrounds the heat-conducting sleeve 12, i.e. the outer coating 11 is disposed outermost of the aerosol-generating article 10. In other embodiments, it is also possible that the outer coating 11 surrounds the segment of aerosol-generating article 13 and the heat-conducting sleeve 12 further surrounds the outer coating 11, i.e. the heat-conducting sleeve 12 is arranged outermost on the aerosol-generating article 10.

The length of the tubular sidewall 121 may be less than, equal to, or greater than the length of the segment of atomizing medium 13. Preferably, the length of the tubular sidewall 121 may be slightly less than, equal to, or slightly greater than the length of the atomizing medium segment 13. The tubular side wall 121 is too short to improve the heat utilization of the segment of atomizing medium 13. The tubular side wall 121 has an excessively large length, so that the tubular side wall 121 wraps part of the cooling section 14, and the cooling effect of the cooling section 14 is affected, and even the upper part of the housing 21 is overheated.

In this embodiment, end wall 122 is closed off. The end wall 122 is of a thin-walled structure, which can be pierced by the heating element 23. When the aerosol-generating article 10 is inserted downwardly into the aerosol-generating device 20, the upper end of the heat-generating body 23 pierces the end wall 122 and is inserted further into the length of atomising medium 13, thereby effecting heating of the length of atomising medium 13 and effecting airflow communication. The upper end of the heat generating body 23 may have a pointed configuration to facilitate piercing of the end wall 122 and insertion into the length of aerosol medium 13.

Fig. 5 shows a heat-conducting jacket 12 in a first alternative of the present invention, which is mainly different from the above-described embodiments in that the end wall 122 of the heat-conducting jacket 12 in the present embodiment is perforated to allow the heat-generating body 23 to pass through and/or allow the air flow to pass through.

Specifically, the end wall 122 is opened with a through hole 1220 through which the heating element 23 passes. The central axis of the through hole 1220 may coincide with the central axis of the end wall 122, and the cross-sectional shape of the through hole 1220 may be adapted to the cross-sectional shape of the heating body 23. Specifically, in the present embodiment, the cross-sectional shape of the through-hole 1220 is substantially rectangular, which is suitable for passing the sheet-shaped heat-generating body 23. The cross-sectional size of the through-hole 1220 may be greater than or equal to the cross-sectional size of the heat-generating body 23. When the cross-sectional size of the through-hole 1220 is larger than that of the heat-generating body 23, the through-hole 1220 also has a ventilation function, and a gap formed between the inner surface of the through-hole 1220 and the outer surface of the heat-generating body 23 can also be used for the passage of the air flow.

Further, the end wall 122 may further be opened with at least one vent 1221 for allowing air flow to pass through. In this embodiment, there are a plurality of vent holes 1221, and the plurality of vent holes 1221 are disposed around the through hole 1220. The cross-sectional shape of the vent hole 1221 may be circular, oval, triangular, square, or the like.

It is understood that in other embodiments, only the through hole 1220 or the vent hole 1221 may be formed on the end wall 122.

Fig. 6 shows a heat conduction sleeve 12 in a second alternative of the present invention, which is different from the first alternative mainly in that the through hole 1220 in the present embodiment is a circular hole, which is suitable for passing through the round bar-shaped heat-generating body 23.

It is to be understood that the above-described technical features may be used in any combination without limitation.

The above examples only represent the preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
