Referring to fig. 1, the present invention provides a smoking aid 300 comprising a carrier 310 and an enhancing substance 320 supported on the carrier 310, wherein the enhancing substance 320 is capable of generating an enhancing gas and/or an enhancing aerosol for enhancing the effectiveness of an aerosol-generating article when heated. By synergistic for use in an aerosol-generating article is meant that the synergistic gas and/or synergistic aerosol may alter the type of components and/or the amount of at least one component of an original aerosol produced by the aerosol-generating article, e.g., the synergistic gas and/or synergistic aerosol may have new components not present in the original aerosol, have at least one component in the original aerosol, may neutralize poor components (e.g., bitter tasting substances) in the original aerosol, and/or may complex with at least one component in the original aerosol to produce new efficacy components. Referring to fig. 2 to 5, the smoking-assistance article 300 and the aerosol-generating article 100 may both be placed in the aerosol-generating device 200 and heated by the aerosol-generating device 200. Preferably, when the smoking material in the aerosol-generating article 100 is heated, the smoking aid 300 may be heated by the same heat source (e.g. the energised heating element 230) that heats the aerosol-generating article 100. The smoking-assistance article 300 absorbs excess heat from the electrically-powered heating element 230 heating the aerosol-generating article 100 to produce the enhanced gas and/or enhanced aerosol. In another embodiment, the aerosol-generating article 100 and the smoking article 300 may be heated separately by different heat sources. The enhancing gas and/or enhancing aerosol can be mixed with the original aerosol generated by the aerosol-generating article 100 to enhance the original aerosol.

The carrier 310 is used for loading the synergistic substance 320, and the smoking-assisting article 300 can be conveniently replaced by loading the synergistic substance 320 on the carrier 310, so that the smoking-assisting article 300 can be made into a replaceable article similar to the aerosol-generating article 100, for example, the smoking-assisting article 300 can be made into a disposable article. The frequency of replacement of the smoking-assistance article 300 and the aerosol-generating article 100 may be the same or different. The user may increase the playability of the aerosol-generating article 100 by replacing smoking-assistance articles 300 with different efficacies, for example, by replacing smoking-assistance articles 300 that are capable of producing different flavors, or smoking-assistance articles 300 that are capable of producing different amounts of smoke, while replacing the aerosol-generating article 100 in the system, or during use of the same aerosol-generating article 100, or after use of a plurality of aerosol-generating articles 100.

The enhancing substance may be provided on the carrier 310 or in the carrier 310, for example on the surface of the carrier 310 or inside the carrier 310. For example, the carrier 310 may be a porous structure having pores, and the enhancing substance may be disposed in the pores of the carrier 310. Preferably, the carrier 310 and the enhancing substance are configured such that the smoking-assistance article 300 is breathable. The carrier 310 may be, for example, at least one of textile, carbon or a derivative of carbon, fiber, non-woven fabric, starch, protein, paper, water-absorbent resin, sponge, gel, or a processed product of at least one of them. The carbon or the derivative of the carbon element may be, for example, a porous carbon material such as a carbon fiber film, a carbon cloth, a carbon nanotube paper, a graphene film, or the like. The fibers may be natural plant or animal fibers, or man-made polymer fibers. The gel can be sol or gel in solution which are mutually connected under certain conditions to form a space network structure, the structural gaps are filled with liquid serving as a dispersion medium to form a dispersion system, and the gel can be organic gel such as glucomannan, agar, pectin, aloe gel, seaweed gel, carboxymethyl cellulose, locust bean gum, carob bean gum, guar gum, xanthan gum, gelatin and the like, and can also be inorganic gel such as silica gel, aluminum hydroxide and the like. The carrier 310 may have a two-dimensional-like structure, such as a sheet, a layer or a film, for convenient arrangement in the aerosol-generating device 200. The carrier 310 may be rigid or flexible, for example, may have some strength, but may be capable of being bent. The thickness of the two-dimensional structure-like carrier 310 may be, for example, 1 micrometer to 5 millimeters, preferably 0.5 millimeters to 2 millimeters. When the carrier 310 has poor air permeability, for example, when the substrate has a non-porous structure, the carrier 310 may have through holes processed for air permeability. The synergistic substance 320 may be at least one of a solid substance, a liquid substance, a semi-solid substance, a gel substance, and a paste substance. The enhancing substance 320 may be adsorbed, coated, packed, encapsulated and/or chemically bound on the carrier 310 or in the carrier 310. In one embodiment, the synergistic material 320 is a solid material, and the synergistic material 320 can be dispersed in the pores of the carrier 310 or attached to the surface of the carrier 310, for example, the solid material can be dispersed in a solvent to form a coating solution to be coated on the surface of the carrier 310, and then the solvent in the coating solution can be removed to attach the solid material to the surface of the carrier 310. In another embodiment, the synergistic substance 320 is a liquid substance that can be adsorbed in the pores of the carrier 310. In another embodiment, the synergistic substance 320 is a semi-solid substance, a gel substance or a paste substance, and the synergistic substance 320 can be coated or attached on the surface of the carrier 310. In another embodiment, the carrier 310 defines a cavity for containing the synergistic substance 320, and the synergistic substance 320 can be filled in the carrier 310. It is to be understood that the synergistic material 320 is not limited to the above embodiments, as long as the synergistic material 320 can be loaded on the carrier 310 to form the integrally movable smoking article 300.

The enhancing substance 320 may include at least one of a fogging agent, nicotine, acid, nicotine salt, and flavor. When the potentiator 320 comprises the aerosol generating agent, the smoking-assistance article 300 can increase the amount of aerosol generated by the aerosol-generating article 100. When the potentiator 320 comprises the nicotine, the smoking-assistance article 300 can enhance the smoke strength of the aerosol-generating article 100. When the synergist 320 includes the acid, a nicotine salt can be formed with free nicotine, so that the throat can be prevented from being excessively stimulated by high nicotine content, and the absorption efficiency of nicotine in a human body can be improved. When the enhancing substance 320 comprises the flavourant, the smoking article 300 may enhance or alter the mouth-feel of the aerosol-generating article 100. Of course, the potentiating substance 320 can include a nicotine salt. The aerosol generating article 100 may be different from or the same as the original aerosol generating article 100 in terms of nicotine, and flavor, and the user may select the smoking assisting article 300 containing different synergists according to his/her preference, and may replace the smoking assisting article 300 containing different synergists every time of smoking, so as to enrich the playability of the aerosol generating article 100. The fogging agent may include at least one of glycerin, propylene glycol, and triacetin. The nicotine may be nicotine. The fragrance may include at least one of an aromatic plant fragrance and an artificial fragrance. Aromatic plant perfume such as aroma component extract of herba Menthae, Lavender, Mandarin orange, flos Rosae Rugosae, flos Osmanthi Fragrantis, flos Jasmini sambac, etc. is in the form of extract or essential oil. Artificially synthesized flavors such as tobacco flavor, including but not limited to at least one of increased flavor, reduced bitterness, increased fullness, increased sweetness, reduced bitterness, and reduced miscellaneous gases. For example, chocolate, milk, fruit, nut, aucklandia, floral, spicy, honey, cream, bean, bread, caramel, phenol, smoke, wine, etc. The temperature at which the enhancing substance 320 produces the enhancing gas and/or enhancing aerosol may be less than the temperature at which the aerosol-generating article 100 produces the original aerosol, for example may be less than 400 degrees celsius. The acid may comprise an organic acid or an inorganic acid. Preferably, the acid source comprises an organic acid selected from at least one of: 3-methyl-2-oxopentanoic acid, pyruvic acid, 2-oxopentanoic acid, 4-methyl-2-oxopentanoic acid, 3-methyl-2-oxobutanoic acid, 2-oxooctanoic acid, benzoic acid, lactic acid.

The smoking aid 300 may have a two-dimensional-like structure, such as a sheet, a layer, or a film. The smoking article 300 can also have a three-dimensional structure, such as a block, a cylinder, or can be bent from a two-dimensional-like structure to form a tubular body structure. The smoking-assistance article 300 can be provided in a variety of shapes, such as circular, annular, rectangular, U-shaped, oval, triangular, polygonal, or irregular. The smoking aid 300 can be configured to have different shapes, such as an animal shape, a figure shape, a fruit shape, a landscape shape, and the like. The overall shape of the smoking-assistance article 300 can be substantially the same as the shape of the carrier 310. The smoking-assistance article 300 can be further bent or crimped so that it can better accommodate the aerosol-generating device 200. The smoking-assistance article 300 may have at least one of voids, pores, and through-holes, thereby making the smoking-assistance article 300 breathable.

In one embodiment, the smoking-assistance article 300 is a layered composite structure formed by combining at least two layers; preferably, at least one of the layers is adsorptive, which may be referred to simply as an adsorbent layer, and may be configured to both adsorb and store smoking aids, and also be simultaneously or separately/specifically configured to absorb tar/condensate, etc., remaining in the aerosol-generating device 200 (i.e., to provide a cleaning function). Preferably, the adsorbent layer is located at the uppermost layer and/or the lowermost layer of the layered composite structure. In the layered composite structure, the layer loaded with the synergistic substances can be referred to as an effect layer for short, the number of the effect layers can be single-layer or multi-layer, and the types and the number of the synergistic substances in each effect layer can be the same or different. For example, each synergistic substance can be loaded on a carrier layer to form different functional layers, and then the functional layers are compounded into a laminated composite structure, which is particularly suitable for the situation that some special synergistic substances are required to be combined with a specific carrier.

In an embodiment, the smoking-assistance article 300 is shaped and dimensioned to be disposed in the gas passage of the aerosol-generating device 200, may be disposed in the entire gas passage, preferably in a partial section of the gas passage.

In an embodiment, the smoking article 300 is heated separately, i.e. the aerosol-generating article 100 and the smoking article 300 may be heated separately by different heat sources, and the heating control system may be shared or provided separately. The smoking-assistance article 300 may also have individual control over the release rate and release time of the enhancing substance therein. The enhanced gas and/or enhanced aerosol generated by heating the smoking-assistance article 300 is collected into the gas passage of the aerosol-generating device 200 and/or the receiving cavity for receiving the aerosol-generating article 100, and the generated amount of the enhanced gas and/or enhanced aerosol is adjusted by controlling the heating temperature of the smoking-assistance article 300. Preferably, the smoking-aid article 300 is heated individually and the amount of enhancement substance carried is controllable, for example, the aerosol-generating device 200 has a cavity for holding the enhancement substance, the control being effected by controlling the rate of transfer of the enhancement substance from the cavity to the smoking-aid article 300. Preferably, the speed and amount of the synergistic gas and/or synergistic aerosol generated by heating the smoking-assisting article 300 which is heated individually and merged into the gas passage or the accommodating cavity can be controlled, for example, the synergistic gas and/or synergistic aerosol generated by heating the smoking-assisting article 300 has an independent gas flow passage, a valve is arranged on the independent gas flow passage, and the speed and amount of the merged gas passage or the accommodating cavity are controlled by the opening and closing size of the valve.

In another embodiment, the smoking-assistance article 300 is shaped and dimensioned to be disposable in a receiving cavity of the aerosol-generating device 200 for receiving the aerosol-generating article 100, preferably at the bottom of the receiving cavity.

The smoking aid 300 may further comprise an encapsulation structure (not shown), in which the carrier 310 and the synergist 320 may be sealed to prevent volatilization of the synergist 320 in the smoking aid 300 when not in use. In use of the smoking article 300, the packaging structure may be removed and placed into the aerosol-generating device 200. The packaging structure can be common packaging containers such as packaging paper, packaging boxes, packaging bags and the like.

Referring to fig. 2 to 5, an aerosol-generating system according to an embodiment of the present invention includes an aerosol-generating article 100, an aerosol-generating device 200, and the smoking-assistance article 300. The aerosol-generating device 200 may be provided with a receiving cavity 201. The aerosol-generating article 100 may be contained in the receiving cavity 201. The aerosol-generating device 200 may further include a gas passage that can communicate with the accommodating chamber 201. The smoking aid 300 may be disposed in the gas pathway and/or in the receiving cavity 201. In particular, the smoking-assistance article 300 is shaped to be able to be disposed in the gas passage of the aerosol-generating device and/or in the receiving cavity 201. When the smoking-assist article 300 is heated alone, the generated gas/aerosol is funneled into the gas pathway and/or into the receiving cavity 201.

The "gas passage" according to embodiments of the present invention refers to the section of the airflow path from the entrance of the aerosol-generating device 200 to the flow into the receiving cavity 201 when the aerosol-generating article 100 is drawn. The heat generated during heating of the smoking material in the aerosol-generating article 100 may further heat the smoking-aid article 300 to generate the synergistic gas and/or synergistic aerogel, and the generated synergistic gas and/or synergistic aerogel may flow along with the airflow in the air passage and enter the accommodating cavity 201, and then flow out of the opening of the accommodating cavity 201 together with the original aerosol generated by the aerosol-generating article 100 after mixing, so as to achieve the effect of enhancing the effect of the aerosol-generating article 100.

When the aerosol-generating article 100 is received in the receiving cavity 201, the smoking-assistance article 300 may be positioned adjacent to the gas-inflow end of the aerosol-generating article 100, opposite the side wall of the aerosol-generating article, and/or around the aerosol-generating article 100, so that the smoking-assistance article 300 may better absorb heat generated by heating the smoking material in the aerosol-generating article 100, thereby achieving better synergy. Preferably, the smoking aid 300 is located at the gas inflow end of the aerosol-generating article 100, i.e. the end where air flows into the aerosol-generating article 100, so that the synergistic gas and/or the synergistic aerosol generated by the smoking aid 300 can be better brought into the aerosol-generating article 100 to be mixed with the original aerogel, and better synergistic effect can be achieved. The thickness direction of the smoking aid 300 having a two-dimensional structure can be arranged along the gas flow direction in the gas passage of the aerosol-generating device 200, so that the airflow can pass through the smoking aid 300 having a larger area, and the synergistic effect can be better exerted.

The aerosol-generating article 100 may comprise a body 110, and the smoking material may be disposed in the body 110. The aerosol-generating article 100 may further comprise a filter 130 disposed at one end of the length of the body 110 and at the air flow out end, the other end of the length of the body 110 being the air flow in end. A buffer section 120 may be further disposed between the cigarette body 110 and the filter 130 for cooling and insulating heat to prevent the aerosol flowing out of the filter 130 from being excessively hot.

The aerosol-generating device 200 may comprise a base 210 and a cover 220 disposed on the base 210. The receiving cavity 201 may be disposed in the upper cover 220. The smoking-aid article 300 may be disposed on the chassis 210 opposite the gas-inflow end of the aerosol-generating article 100.

Preferably, the aerosol-generating article 100 may be spaced from the gas inflow end of the smoking article 300 to further facilitate the production of the synergistic gas and/or synergistic aerogel.

Referring to fig. 5 and 6, in an embodiment, the accommodating chamber 201 has a tubular inner wall, and the tubular inner wall is disposed on the base 210. The aerosol-generating article 100 may further be supported by the chassis 210. In this case, a recess 205 may be formed in the base 210 surrounded by the receiving cavity 201, and the smoking article 300 may be disposed in the recess 205 so as to be spaced apart from the gas inlet end of the aerosol-generating article 100.

Referring to fig. 2 to 4, in another embodiment, the bottom wall 224 of the accommodating chamber 201 may have a tubular side wall and the bottom wall 224 is disposed at one end of the tubular side wall. The bottom wall 224 may be spaced opposite the base 210. The smoking-assistance article 300 may be disposed between the bottom wall 224 and the base 210 so as to be spaced opposite the gas inflow end of the aerosol-generating article 100.

Specifically, the upper cover 220 may include a first cylinder 221 and a second cylinder 222 sleeved in the first cylinder 221 and spaced apart from the first cylinder 221. The inner cavity of the second cylinder 222 may form the accommodating chamber 201. The first end of the second cylinder 222 may have an opening and the second end may be provided with the bottom wall 224, and the aerosol-generating article 100 may be further supported by the bottom wall 224 after being received in the receiving cavity 201. Both ends of the first cylinder 221 may have openings, and the first end of the first cylinder 221 may be connected to the first end of the second cylinder 222, for example, by an annular plate 223. The length of the first cylinder 221 may be greater than the length of the second cylinder 222. The second end of the first cylinder 221 may be disposed on the base 210 such that the bottom wall 224 is spaced apart from the base 210.

Further, a first through hole 203 may be opened in a circumferential wall of the first cylinder 221, and a second through hole (not shown) may be provided in the support plate, and the gas passage may extend from the first through hole 203 to the second through hole through a gap between the first cylinder 221 and the second cylinder 222.

Referring to fig. 4, in an embodiment, the overall shape of the smoking assisting article 300 may match the overall shape of the air passage or correspond to the overall shape of the second cylinder 222, for example, the smoking assisting article 300 may be configured as a cylinder structure with an open end and disposed in the air passage between the first cylinder 221 and the second cylinder 222, so as to exert a better synergistic effect. In another embodiment, as shown in fig. 2, the smoking article 300 may also be provided as a sheet-like structure disposed between the receiving cavity 201 and the base 210, for example, between the bottom wall 224 and the base 210. In another embodiment, the smoking assisting article 300 may be disposed on only one side of the accommodating cavity 201, or disposed around the accommodating cavity 201.

The cover 220 and the base 210 may be detachably connected, for example, the second end of the first cartridge body 221 may be detachably connected to the base 210, so as to facilitate the arrangement of the smoking-assisting article 300 on the base 210. A stop element 212 may further be provided on the base 210 to enable the cover 220 to be accurately mounted on the base 210 with the energised heating element 230 accurately inserted into the smoking material of the aerosol-generating article 100. The limiting element 212 may be a cylindrical structure with an outer diameter matched with the inner diameter of the first cylinder 221, so that the first cylinder 221 may be just sleeved outside the limiting element 212, and thus the flow of the gas flow in the gas passage may not be affected. Referring to fig. 3, a semicircular slot 204 may be formed along a direction perpendicular to the length direction of the limiting element 212, and the smoking accessories 300 may be put into the base 210 from the semicircular slot 204, so that the smoking accessories 300 may be conveniently disposed.

The smoking article 300 may be spaced from the base 210 in a suspended configuration, thereby allowing a greater surface of the smoking article 300 to contact the airflow and thereby better generating the synergistic gas and/or aerogel. Referring to fig. 1, in an embodiment, the smoking assisting article 300 may be suspended on the base 210 by a bracket 260, so as to be spaced from the base 210.

In another embodiment, referring to fig. 7, the smoking assisting article 300 may also be disposed in the accommodating cavity 201, for example, may be disposed at the bottom end of the accommodating cavity 201.

The aerosol-generating device 200 may further comprise an electrically energized heating element 230 disposed adjacent to a smoking material of the aerosol-generating article 100, capable of heating the smoking material. The energization heating element 230 may be an element capable of converting electric energy into heat energy. A power source 240 may further be provided in the base 210, and the power source 240 may be electrically connected to the electric heating element 230 for providing electric current to the electric heating element 230. A controller 250 electrically connected to the power supply 240 and the electric heating element 230, respectively, may be further disposed in the base 210 for controlling the on/off of the electric heating element 230, adjusting the voltage and current, and the like.

Referring to figures 2, 3 and 4, in an embodiment, the electrically-powered heating element 230 is disposed on the base 210 and is capable of being inserted into the smoking material of the aerosol-generating article 100 to heat the aerosol-generating article 100, for example, the electrically-powered heating element 230 may be an electrically-powered heating sheet, an electrically-powered heating rod, or an electrically-powered heating pin disposed perpendicular to the base 210. The electric heating element 230 extends from the base 210 to the accommodating chamber 201 through the bottom wall 224. The height of the energised heating element 230 is adapted to the length of a smoking material segment of the aerosol-generating article 100, which can extend substantially throughout the smoking material segment. The bottom wall 224 is opened with a through hole corresponding to the position of the electric heating element 230, so that the electric heating element 230 can pass through the through hole, and the accommodating cavity 201 can be communicated with the gas passage. Referring to fig. 1, the smoking-assistance article 300 may have a third through-hole 304 that is adapted to the cross-sectional shape of the energized heating element 230, such that the energized heating element 230 may be inserted through the smoking-assistance article 300 into the smoking material of the aerosol-generating article 100.

In this embodiment, the support 260 may be further connected to the electric heating element 230, for example, the support 260 may be directly sleeved on the electric heating element 230, the support 260 may be integrally disposed with the electric heating element 230, or the support 260 may be electrically connected to the electric heating element 230, and the support 260 may be made of an electric heating material, so that the support 260 may also be powered on, and heat the smoking-assisting article 300, thereby further improving the synergistic effect of the smoking-assisting article 300. The support 260 may be, for example, a metal conductive mesh.

Referring to fig. 5 and 6, in another embodiment, the electrically-powered heating element 230 may be disposed on a peripheral wall of the receiving cavity 201, and after the aerosol-generating article 100 is inserted into the receiving cavity 201, the electrically-powered heating element 230 may be disposed adjacent to the smoking material of the aerosol-generating article 100, thereby heating the smoking material of the aerosol-generating article 100. The electrically-powered heating element 230 may be in contact with or spaced apart from the aerosol-generating article 100. The energized heating elements 230 may be arranged in a two-dimensional-like configuration, such as a film, a sheet. The electrically energised heating element 230 may also be provided as a cylindrical structure so as to fit around the periphery of the aerosol-generating article 100.

Referring to fig. 8, in another embodiment, the electrically-powered heating element 230 may not be disposed in the aerosol-generating device 200, but rather, the aerosol-generating article 100 itself may have an element that wraps, is wrapped by, and/or is disposed in the smoking material, which may allow for better and sufficient contact between the smoking material 110 and the electrically-powered heating element 230 during the manufacturing process of the aerosol-generating article 100, thereby improving heating efficiency. At this point, the aerosol-generating device 200 need only provide electrical energy to the aerosol-generating article 100 to effect heating of the aerosol-generating article 100. The shape and configuration of the electrically-powered heating element 230 may vary and need not have high strength to withstand the pressure experienced by multiple insertions of smoking material. The aerosol-generating article 100 may be a disposable article and thus the electrically-conductive heating element 230 may also be disposable, avoiding problems associated with repeated use of the electrically-conductive heating element 230, such as contamination and build-up of harmful substances caused by the difficulty in removing tar and other substances remaining on the surface of the electrically-conductive heating element 230. The electrically powered heating element 230 may be wrapped around the entire tobacco material, for example, may be wrapped around the entire tobacco body 110 to form a cylindrical structure. The electrical heating element 230 itself may also serve as a cigarette paper or a carrier tube, and as a whole, it may wrap, support and contain the tobacco while being electrically heated.

The aerosol-generating device 200 further comprises device electrodes, such as a first device electrode 232 and a second device electrode 234, disposed in the receiving cavity 201 for supplying power to the energized heating element 230. In theory, the two ends of the electrical heating element 230 are connected to the device electrodes of the aerosol-generating device 200, so that the electrical heating element 230 can be powered, and the purpose of electrically heating the tobacco material is achieved. For example, when the electric heating element 230 is a cylindrical structure and is wrapped outside the smoking material, the portion of the electric heating element 230 opposite to the device electrode may be directly contacted with the device electrode so as to be electrically connected. For better electrical connection with the device electrodes, the aerosol-generating article 100 may include article electrodes, such as a first article electrode 132 and a second article electrode 134. The material of the product electrode may be a material having better conductivity than the conductive heating element 230, and the form may be a layer, a film, a filament, a sheet, a block, or the like. The product electrodes may be welded, snap-fit connected, or bonded with the energization heating elements 230, respectively. Alternatively, the product electrode may be formed on the surface of the energization heating element 230 by plating, spraying or printing.

In order to facilitate mutual contact and thus electrical connection between a device electrode of the aerosol-generating device 200 and an article electrode of the aerosol-generating article 100, the position of the device electrode in the receiving cavity 201 corresponds to the position of the article electrode on the aerosol-generating article 100, which is facing the article electrode when the aerosol-generating article 100 is arranged in the aerosol-generating device 200. More preferably, the dimensions, e.g. the radial dimensions, of the aerosol-generating article 100 are matched to the dimensions, e.g. the radial dimensions, of the receiving cavity 204 such that the device electrodes and the article electrodes are in contact with each other at an early stage of use.

In one embodiment, the holder 260 may be made of an electrically heated material, and the holder 260 may be further electrically connected to the power supply 240, so that the holder 260 may also be electrically connected to heat the smoking-assisting article 300, thereby further improving the synergistic effect of the smoking-assisting article 300. The support 260 may be, for example, a metal conductive mesh.

It will be appreciated that in other embodiments, the smoking-assistance article may also be in direct contact with the substrate and/or the aerosol-generating article, and may also act synergistically. When the substrate is in direct contact with the smoking article, the substrate may be provided as a mesh substrate or a porous substrate to allow airflow therethrough.

The smoking assisting article provided by the invention can be matched with the aerosol generating device, so that the smoke quantity and the smoke strength of the aerosol generated by the aerosol generating system are increased, and/or the taste of the original aerosol generated by the aerosol generating article is adjusted or changed. The smoking assisting article is independent of the aerosol generating article and is convenient to replace independently, so that a user can experience different smoking tastes or visual impressions conveniently, and the playability of the aerosol generating system is richer.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
