Description

Technical Field

[0001] The present application relates to the technical field of smoke generation, and in particular to an atomization base, an aerosol generating device and an aerosol generating product. Background Art

[0002] Aerosol generating products generally generate aerosols by heating without burning. Specifically, an aerosol generating matrix is ​​provided in the aerosol generating product. The aerosol generating matrix is ​​heated by an external heat source so that it is heated just enough to emit a fragrance. The aerosol generating matrix does not burn, but instead loads an atomizer and releases the atomizer by heating when in use to form smoke.

[0003] In the related art, there is a heating method that performs single-sided local heating on the outer wall of an aerosol generating matrix having multiple airways. This heating method only heats a portion of the outer wall of the aerosol generating matrix each time. After a single heating is completed, the aerosol generating matrix is ​​rotated to heat another portion of the outer wall.

[0004] However, during the heating process, aerosols are only produced in several airways near the heated outer wall, and almost no aerosols are produced in other airways. During the user's inhalation process, the external airflow will disperse into each airway, and only part of the airflow entering the airway with aerosol can carry the aerosol out, resulting in about 50% of the aerosol being difficult to be stably inhaled, and the aerosol capture rate is relatively low.

DETAILED DESCRIPTION

[0060] The present application embodiment provides an aerosol generating device 10, see Figures 1 to 19 The aerosol generating device 10 can be used in conjunction with an aerosol generating article 20 having a plurality of first air channels 212 .

[0061] Specifically, the aerosol generating device 10 heats and atomizes the aerosol generating product 20 to generate an aerosol for a user to inhale or for use in medicine, beauty, and the like.

[0062] See also Figure 1 and Fig.13 The aerosol generating device 10 includes a shell 11, an atomizing base 13, a laser generating device 12 and a rotating driving mechanism 14.

[0063] The housing 11 is provided with an inserting channel 11 a having an inserting port 11 b at one end, and the inserting port 11 b is used for inserting the aerosol generating product 20 into the inserting channel 11 a .

[0064] See also Figure 1 and Fig.13 After the aerosol generating article 20 is inserted into the insertion channel 11 a , at least a portion of the aerosol generating article 20 is located in the insertion channel 11 a .

[0065] See also Figures 2 to 4 , Figures 14 to 16 The atomizing base 13 is formed with a mounting groove 13a and an air inlet 13d communicating with the mounting groove 13a. The mounting groove 13a is used to accommodate at least a portion of the aerosol generating product 20.

[0066] The atomizer base 13 is disposed in the housing 11 and is located at an end of the plug-in channel 11 a opposite to the plug-in port 11 b , and the mounting groove 13 a is communicated with the plug-in channel 11 a .

[0067] The mounting groove 13a of the atomizing base 13 is used to limit the aerosol generating product 20. Specifically, one side of the mounting groove 13a has a mounting opening 13b, the mounting opening 13b faces the plug port 11b, and one end of the aerosol generating product 20 extends into the mounting groove 13a from the mounting opening 13b.

[0068] The material of the atomizer base 13 is not limited. For example, the material of the atomizer base 13 can be silicone, TPU (Thermoplastic Urethane), PLA (polylactic acid), PC (Polycarbonate), PEEK (polyetheretherketone), PTFE (Polytetrafluoroethylene), etc.

[0069] The air inlet 13d is used to allow external airflow to flow into the first air channel 212. Specifically, the atomizing base 13 and the aerosol generating product 20 move relative to each other so that the air inlet 13d is connected to some of the first air channels 212. In other words, the atomizing base 13 may remain stationary, and the aerosol generating product 20 may move relative to the atomizing base 13, or the aerosol generating product 20 may remain stationary, and the atomizing base 13 may move relative to the atomizing base 13. In short, the air inlet 13d will only be connected to some of the first air channels 212, but not to all of the first air channels 212.

[0070] In addition, it should be noted that the number of the first air passage 212 communicating with the air inlet 13d may be one or more than one.

[0071] For example, see Figures 2 to 4 , Figures 14 to 16 The atomizing base 13 includes a bottom wall 131 and a side wall 132 located on one side of the bottom wall 131. The bottom wall 131 and the side wall 132 surround a mounting groove 13a. The mounting opening 13b is located on a side opposite to the mounting groove 13a and the bottom wall 131. The air inlet 13d can be as shown in Figure 3 As shown, it is arranged on the bottom wall 131, and can also be arranged as Fig.15 and Fig.16 The arrangement shown is on the side wall 132 .

[0072] Please continue reading Figure 1 and Fig.13 The laser generating device 12 is disposed in the housing 11 and is used to heat a portion of the outer wall of the aerosol generating product 20 .

[0073] Specifically, the laser generating device 12 is used to generate laser light, and the laser light is used to locally heat a single side of the aerosol generating article 20 .

[0074] Single-sided local heating refers to the heating component in the aerosol generating device 10 (such as Figure 1 and Fig.13 The laser generating device 12 shown is arranged on the periphery of the aerosol generating product 20 to bake and heat the aerosol generating product 20 from the outside to the inside, wherein the heating component only heats a portion of the outer wall of the aerosol generating product 20 each time, and after a single heating is completed, the aerosol generating product 20 or the atomizing base 13 is rotated to heat another portion of the outer wall of the aerosol generating product 20.

[0075] See also Figure 1 and Fig.13 Since the laser performs local heating on one side of the aerosol generating article 20, only a portion of the first air channel 212 is within the irradiation range of the laser during the heating process.

[0076] For example, see Figure 1 and Fig.13 The laser generating device 12 can be arranged outside the insertion channel 11 a , with the emission end of the laser generating device 12 facing the insertion channel 11 a , so as to achieve single-sided local heating of the aerosol generating product 20 .

[0077] It should be noted that the heating method for single-sided local heating is not limited to laser. For example, single-sided local heating can also be performed by resistance, electromagnetic, infrared, microwave and other heating methods. Therefore, the atomization base 13 is not limited to being set in an aerosol generating device 10 with a laser generating device 12. The atomization base 13 described in the embodiment of the present application can be set in any other aerosol generating device 10 that uses single-sided local heating.

[0078] Please continue reading Figure 1 and Fig.13 The rotation driving mechanism 14 drives one of the atomizing base 13 and the aerosol generating product 20 to rotate, so that the air inlet 13d is connected to the first air channel 212 located within the irradiation range of the laser generating device 12.

[0079] That is to say, the rotation drive mechanism 14 can drive the aerosol generating product 20 to rotate relative to the atomizing base 13, and can also drive the atomizing base 13 to rotate relative to the aerosol generating product 20, so that the air inlet 13d can be connected to the first airway 212 located within the irradiation range of the laser generating device 12.

[0080] It should be noted that when the number of first air channels 212 within the irradiation range of the laser generating device 12 is greater than one, the air inlet 13d may be connected to a portion of the first air channels 212 or to all of the first air channels 212 within the irradiation range.

[0081] For example, see Figures 1 to 4 , Fig.13 , Fig.16 The rotating driving mechanism 14 has a connecting head 14a, and a driving mechanism avoidance port 13c can be set on the bottom wall 131 of the mounting groove 13a. The connecting head 14a passes through the driving mechanism avoidance port 13c to extend into the mounting groove 13a and connect with the aerosol generating product 20. Thus, the rotating driving mechanism 14 can drive the aerosol generating product 20 to rotate relative to the atomizing base 13.

[0082] Exemplarily, the aerosol generating device 10 may also be provided with a plurality of laser generating devices 12, each of which heats the outer wall of different circumferential regions of the aerosol generating product 20, respectively. The connector 14a of the rotating drive mechanism 14 may be connected to the atomizing base 13, and the rotating drive mechanism 14 may drive the atomizing base 13 to rotate relative to the driving aerosol generating product 20, and may also connect the air inlet 13d with the first airway 212 within the irradiation range of the corresponding laser generating device 12.

[0083] Combine the following Figure 1 and Fig.13 The aerosol generating product 20 shown in the figure further describes the aerosol generating device 10 described in the embodiment of the present application in detail. It should be noted that the aerosol generating device 10 described in the embodiment of the present application is not limited to the aerosol generating device 1 and Fig.13 The aerosol generating device 10 is used in conjunction with the aerosol generating article 20 shown in the figure. The aerosol generating device 10 can also be used in conjunction with other aerosol generating articles 20 having an airway.

[0084] See also Figures 5 to 9 , Figures 17 to 19 An aerosol generating article 20 used in conjunction with the aerosol generating device 10 includes an aerosol generating substrate 21 and a partition segment 22 .

[0085] The aerosol generating device 10 generates aerosol from the aerosol generating substrate 21 by heating the aerosol generating substrate 21 .

[0086] The aerosol generating matrix 21 has an air inlet side X1 and an air outlet side X2 which are arranged relatively to each other. The aerosol generating matrix 21 includes a base portion 211 and a plurality of first air channels 212 surrounding the base portion 211. Each first air channel 212 extends from the air inlet side X1 to the air outlet side X2, and at least one end of each first air channel 212 close to the air inlet side X1 is an open end. That is to say, at least one end of each first air channel 212 close to the air inlet side X1 is connected to the outside world, and the end of each first air channel 212 close to the air outlet side X2 can be an open end or a closed end that is not connected to the outside world.

[0087] The specific structure of the aerosol generating matrix 21 is not limited here. For example, in one embodiment, the aerosol generating matrix 21 can be made of the atomizing medium itself, for example, made of a smoke flavoring medium. In other embodiments, the aerosol generating matrix 21 can also include a matrix and an atomizing medium disposed on the matrix. The matrix can be, for example, high-temperature resistant carbon fiber. In this way, by providing the matrix, the strength of the aerosol generating matrix 21 can be improved, and it can also withstand a certain degree of high temperature without generating odor.

[0088] The specific components of the aerosol generating matrix 21 are not limited herein. For example, in one embodiment, the aerosol generating matrix 21 may include plant components, auxiliary components, smoke generating agent components, adhesive components, and the like.

[0089] In one embodiment, the plant component is one or more combinations of powders formed by crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and aromatic plants. The plant component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human blood through atomization, promote the pituitary gland to produce dopamine, and thus obtain physiological satisfaction.

[0090] In one embodiment, the auxiliary agent component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeleton support for the plant component, and the inorganic filler also has micropores, which can increase the porosity of the wall material after the plant component is formed, thereby increasing the aerosol release rate.

[0091] The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity of the particles, reduce the friction between the particles, make the overall density of the particle distribution more uniform, and also reduce the pressure required for mold molding and reduce the wear of the mold.

[0092] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can slow down the loss of flavor substances during storage to a certain extent, increase the stability of flavor substances, and improve the sensory quality of products. Emulsifiers (also known as surfactants) can reduce the interfacial tension of water-soluble and water-insoluble components in the mixed system, and form a relatively strong film on the surface of the droplets or form a double electric layer on the surface of the droplets due to the charge given by the emulsifier, preventing the droplets from aggregating with each other and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0093] The function of the smoke-generating agent component is to generate a large amount of steam when heated, thereby increasing the amount of smoke of the smoking product. In one embodiment, the smoke-generating agent may include, for example: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol and glycerol); an ester of a polyhydric alcohol (such as monoacetin, diacetin or triacetin); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) or one or more combinations thereof.

[0094] In one embodiment, the adhesive component is a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is in close contact with the interface of the product component material by wetting, generating an intermolecular attraction, thereby playing the role of bonding the powder, liquid, etc. of the component material. At the same time, the use of natural plant extracts and non-ionic adhesives can avoid the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0095] In one embodiment, the aerosol generating matrix 21 may further include a light absorbing material. The light absorbing material is a material with a high absorption rate for laser light and may be better suited for laser heating.

[0096] Exemplarily, the aerosol generating matrix 21 can be a particle combination, and the particle combination is a reconstituted tobacco medium, for example, a reconstituted tobacco medium containing components such as smoke-generating agent and tobacco. The aerosol generating matrix 21 is an integrated structure, for example, an integrated structure that can be formed by injection molding, compression molding or extrusion technology. Wherein extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and is continuously made into various cross-section products or semi-finished products through the die. The aerosol matrix formed by extrusion molding is in strip shape.

[0097] Since the aerosol generating matrix 21 is a particle combination, it is an integrated medium when the aerosol generating matrix 21 is heated and sucked or stops being heated, and is not prone to disintegration and falling off. This solves the problems in the prior art of the thin sheet, filamentary or loose particle aerosol generating matrix 21, such as loose sheets, falling of filamentary components and particle components, and difficulty in cleaning.

[0098] The shape of the aerosol generating substrate 21 is not limited, as long as the first air channel 212 can be provided. Figure 6 , the aerosol generating substrate 21 may be columnar. The cross-section of the columnar aerosol generating substrate 21 may be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack-shaped, irregular, etc., wherein irregular refers to other symmetrical or asymmetrical shapes other than the shapes listed above.

[0099] The air inlet side X1 of the aerosol generating matrix 21 is one end where the external airflow flows into the aerosol generating matrix 21, and the air outlet side X2 of the aerosol generating matrix 21 is one end where the airflow flows out of the aerosol generating matrix 21, that is, the flow direction of the airflow is from the air inlet side X1 of the aerosol generating matrix 21 to the air outlet side X2.

[0100] The first air channel 212 is a passage for air flow to pass through the aerosol generating substrate 21 , and the aerosol released by the aerosol generating substrate 21 during the heating process will also enter the first air channel 212 .

[0101] The number of the first air passages 212 may be two or more.

[0102] For example, see Figure 7 The aerosol generating substrate 21 may include a plurality of protrusions 213 , and the plurality of protrusions 213 surround the periphery of the base portion 211 , and a first air channel 212 is formed between two adjacent protrusions 213 .

[0103] Exemplarily, a plurality of first air channels 212 may also be formed inside the aerosol generating substrate 21 .

[0104] Please continue reading Figures 6 to 10 The partition section 22 is arranged on the air intake side X1, and the partition section 22 includes a plurality of air intake passages 2211 separated from each other. The partition section 22 separates the plurality of first air passages 212 through each air intake passage 2211, and each air intake passage 2211 is respectively connected to at least one first air passage 212.

[0105] The partition section 22 is used to extend into the atomizing base 13 and connect with the connector 14 a.

[0106] Exemplarily, the partition segment 22 may be provided with a rotating connector 222 and a partition 221 having a plurality of air inlet channels 2211 , and the connector 14 a is connected to the rotating connector 222 .

[0107] The material of the separator 221 can be food-grade silicone, PLA, PEEK, etc.

[0108] The material of the rotating connecting member 222 can be high-density filter cotton.

[0109] See also Figures 8 to 10 The partition 221 may be provided with a plurality of grille bars 2212 , and an air intake channel 2211 is formed between adjacent grille bars 2212 .

[0110] Exemplarily, the length of the grid bar 2212 may be 2 mm to 10 mm (including end points), for example, the length of the grid bar 2212 may be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc.

[0111] See also Fig.12 The separator 221 may also be provided with a main body 2214 having an annular hollow area, and a corrugated structure 2215 is provided in the hollow area to form an air inlet channel 2211.

[0112] In other embodiments, the corrugated structure 2215 may also be replaced by relatively loose filter cotton.

[0113] The air inlet channel 2211 is used to communicate with the air inlet port 13 d . The external airflow enters the air inlet channel 2211 from the air inlet port 13 d , and then enters the first air channel 212 communicated with the air inlet channel 2211 from the air inlet channel 2211 .

[0114] Each air inlet channel 2211 can only be connected to a part of the first air channels 212 on the aerosol generating substrate 21 , and any air inlet channel 2211 cannot be connected to all the first air channels 212 on the aerosol generating substrate 21 at the same time.

[0115] For example, see Fig.10 The air intake channels 2211 can be connected to the first air channels 212 in a one-to-one correspondence, that is, the number of the air intake channels 2211 is the same as the number of the first air channels 212, each air intake channel 2211 is only connected to one first air channel 212, and the same first air channel 212 will not be connected to two or more air intake channels 2211.

[0116] For example, see Fig.11 When the number of the first air passages 212 is at least three, each air intake passage 2211 may also be communicated with two adjacent first air passages 212 respectively.

[0117] See also Figure 1 and Fig.13After the partition section 22 is connected to the connector 14a, the air inlet 13d on the atomizer base 13 will only be connected to part of the air inlet channels 2211, that is, the air inlet 13d can be connected to one air inlet channel 2211, or more than one air inlet channel 2211, but not to all of the air inlet channels 2211. The external airflow mainly flows into the first air channel 212 corresponding to the air inlet 13d, and almost does not flow into other first air channels 212.

[0118] See also Figure 6 and Fig.18 The aerosol generating product 20 may also be provided with a functional section 23 on the air outlet side X2 of the aerosol generating matrix 21. The functional section 23 may only be provided with a filtering section for filtering the aerosol, or may be provided with a filtering section and a cooling section. For the functional section 23 provided with a cooling section, the cooling section is provided between the filtering section and the aerosol generating matrix 21, so as to cool the aerosol before the filtering section filters the aerosol, so as to reduce the temperature of the aerosol and improve the "hot mouth" phenomenon when the user inhales the aerosol.

[0119] See also Figure 5 and Fig.17 The aerosol generating article 20 may further be provided with an outer wrapping layer 24 , which is coated on the outer peripheral side of the aerosol generating substrate 21 , the partition segment 22 and the functional segment 23 .

[0120] Also, see Fig.17 For the atomizer base 13 with the air inlet 13d disposed on the side wall 132, an air hole 24a communicating with the air inlet channel 2211 may be disposed on the outer wrapping layer 24, and the air inlet 13d is communicated with the air inlet channel 2211 through the air hole 24a.

[0121] by Figure 1 and Fig.13 Taking the aerosol generating device 10 shown as an example, during the process of loading the aerosol generating product 20 into the aerosol generating device 10, one end of the aerosol generating product 20 provided with the partition section 22 is inserted into the plug-in channel 11a from the plug-in interface 11b, and moves along the plug-in channel 11a toward the atomizer base 13, and finally the partition section 22 enters the installation groove 13a from the installation port 13b of the atomizer base 13 and is connected to the connector 14a.

[0122] Please continue reading Figure 1 and Fig.13Since the air inlet 13d can be connected to the first airway 212 located within the irradiation range of the laser generating device 12, the aerosol generated by the heated aerosol generating matrix 21 will enter the first airway 212 corresponding to the air inlet 13d, which is equivalent to the external airflow and the aerosol generated by the heated aerosol generating matrix 21 both entering the first airway 212 corresponding to the air inlet 13d. Therefore, during the user's inhalation process, a large amount of airflow can carry the aerosol out of the first airway 212, and the aerosol capture rate can reach more than 90%, thereby greatly improving the aerosol capture rate.

[0123] In one embodiment, please refer to Figure 1 , Figure 7 and Fig.13 A second air channel 214 may be further provided inside the base portion 211, and the second air channel 214 runs through the air inlet side X1 and the air outlet side X2. The second air channel 214 may collect aerosol generated by the base portion 211 when heated, so that the aerosol can flow through the second air channel 214 to improve the extraction efficiency of the aerosol.

[0124] For an aerosol generating substrate 21 provided with a second air channel 214, illustratively, see Figure 1 , Figure 6 and Figure 8 The partition 221 may be provided with a blocking channel 2216, a plurality of air inlet channels 2211 surround the blocking channel 2216, the blocking channel 2216 is communicated with the second air channel 214, and the rotating connecting member 222 may at least be provided in the blocking channel 2216, that is, the rotating connecting member 222 may be as follows Figure 1 , Figure 6 and Figure 8 The illustrated embodiment is only provided in the blocking channel 2216, but can also be provided in both the blocking channel 2216 and the second airway 214 to block the second airway 214. The rotating connector 222 has the functions of connecting with the connector 14a of the rotating drive mechanism 14 and blocking the second airway 214 at the same time.

[0125] For example, see Fig.13 , Fig.18 and Fig.19 The partition segment 22 may also be provided with a partition 221 having a shielding portion 2213, and a plurality of air inlet channels 2211 surround the shielding portion 2213. The shielding portion 2213 shields the airway opening of the second airway 214 located on the air inlet side X1, that is, the shielding portion 2213 blocks the external airflow from flowing into the second airway 214, and the rotating connecting member 222 is provided on the side of the partition 221 away from the aerosol generating matrix 21.

[0126] Specifically, the second air duct 214 runs through the air inlet side X1 and the air outlet side X2, which can facilitate the processing of the second air duct 214. However, during the heating process of the laser generating device 12, the aerosol mainly enters the first air duct 212 corresponding to the air inlet 13d, and only a small amount of aerosol enters the second air duct 214. Therefore, the air duct opening of the second air duct 214 on the air inlet side X1 can be blocked or blocked to prevent the external airflow from flowing into the second air duct 214.

[0127] In addition, it should be noted that although the external airflow cannot flow into the second airway 214, the aerosol in the second airway 214 can still flow out of the second airway 214 during the inhalation process, but the effect is relatively poor compared to using the external airflow to extract the aerosol.

[0128] In one embodiment, please refer to Figures 2 to 4 The bottom wall 131 has an outer surface 131a away from the mounting groove 13a and an inner surface 131b close to the mounting groove 13a. For the atomizer base 13 with an air inlet 13d arranged on the bottom wall 131, the air inlet 13d has a first opening 13d1a located on the outer surface 131a and a second opening 13d2a located on the inner surface 131b. The cross-sectional size of the first opening 13d1a can be smaller than the cross-sectional size of the second opening 13d2a.

[0129] Specifically, since the bottom wall 131 has a certain thickness, after the air inlet 13d penetrates the bottom wall 131 , a first opening 13d1a is formed on the outer surface 131a of the bottom wall 131 , and a second opening 13d2a is formed on the inner surface 131b of the bottom wall 131 .

[0130] When the external air flow passes through the air inlet 13d, it enters the air inlet 13d from the first opening 13d1a and then flows out from the second opening 13d2a.

[0131] The cross-sectional dimension of the first opening 13d1a is smaller than that of the second opening 13d2a, and can play a role in adjusting the suction resistance to meet the suction resistance requirement during suction.

[0132] The shape of the first opening 13d1a is not limited, for example, Figure 2 and Figure 3 The first opening 13d1a shown in the figure is circular, and the circular first opening 13d1a is easy to process and manufacture.

[0133] Exemplarily, the diameter of the first opening 13d1a may be 0.5 mm to 1.5 mm (including the end values). For example, the diameter of the first opening 13d1a may be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, etc.

[0134] In other embodiments, the first opening 13d1a may also be a polygon (including but not limited to a triangle, a square, a prism, etc.), an ellipse, a racetrack, an irregular shape, etc.

[0135] The shape of the second opening 13d2a is also not limited. For example, the second opening 13d2a can be Figure 2 and Figure 3 The long strip shape shown extends along the circumference of the bottom wall 131. The long strip shape extending along the circumference of the bottom wall 131 can facilitate the air inlet 13d to be connected with a plurality of first air channels 212 located within the irradiation range of the laser.

[0136] In other embodiments, the second opening 13d2a may also be a polygon (including but not limited to a triangle, a square, a prism, etc.), an ellipse, a racetrack, an irregular shape, etc.

[0137] See also Figures 2 to 4 The air inlet 13d may include a first section 13d1 having a first opening 13d1a and a second section 13d2 having a second opening 13d2a, and at least one of the first section 13d1 and the second section 13d2 is a uniform cross-sectional structure.

[0138] A uniform cross-sectional structure is one whose cross-sectional dimensions remain constant.

[0139] Figures 2 to 4 The first section 13d1 and the second section 13d2 are both equal cross-sectional structures, that is, the cross-sectional dimensions of the entire first section 13d1 are the same as the cross-sectional dimensions of the first opening 13d1a, and the cross-sectional dimensions of the entire second section 13d2 are the same as the cross-sectional dimensions of the second opening 13d2a.

[0140] The first section 13d1 and the second section 13d2 both have equal cross-sectional structures, which can facilitate the processing of the air inlet 13d.

[0141] In other embodiments, one of the first section 13d1 and the second section 13d2 may be a structure of equal cross section, for example, the first section 13d1 may be a structure of equal cross section and the second section 13d2 may be a structure of variable cross section, or the first section 13d1 may be a structure of variable cross section and the second section 13d2 may be a structure of equal cross section. A structure of variable cross section refers to a structure with variable cross section size, that is, the cross section size at at least one position on the structure of variable cross section is different from the cross section size at other positions on the structure of variable cross section.

[0142] In other embodiments, the cross-sectional size of the air inlet 13d may also gradually increase from the first opening 13d1a to the second opening 13d2a, that is, the air inlet 13d has no obvious segmentation, and the cross-sectional size of the air inlet 13d gradually changes from the first opening 13d1a to the second opening 13d2a.

[0143] In one embodiment, please refer to Fig.14 and Fig.15 For the atomizer base 13 in which the air inlet 13d is arranged on the side wall 132, the air inlet 13d may be a hole with four sides closed, that is, the side wall 132 may be formed with an opening to form the air inlet 13d.

[0144] In another embodiment, see Fig.16 The air inlet 13d may also be in the shape of a gap opened on one side close to the mounting port 13b.

[0145] See also Figures 14 to 16 Regardless of whether the air inlet 13d is hole-shaped or notch-shaped, the air inlet 13d can extend along the circumference of the side wall 132 so that the air inlet 13d can be connected to a plurality of first air channels 212 within the irradiation range of the laser.

[0146] See also Figures 14 to 16 Part of the side wall 132 may also protrude into the mounting groove 13a to form an annular sealing rib 132a.

[0147] The annular sealing rib 132 a is used for sealing contact with the aerosol generating product 20 to improve the sealing performance between the aerosol generating product 20 and the atomizing base 13 .

[0148] The annular sealing rib 132a may be a ring with four sides closed, or a ring with an opening.

[0149] For example, see Figures 14 to 16 At least two annular sealing ribs 132a may be provided, and annular sealing ribs 132a may be provided on the side of the air inlet 13d close to the mounting port 13b and the side away from the mounting port 13b, respectively, to improve the sealing performance.
