Background Art

[0002] In existing aerosol generating devices, the heating element is configured to generate heat as it is penetrated by a changing magnetic field, thereby evaporating a liquid substrate to generate an aerosol.

[0078] To facilitate understanding of this application, a more detailed description of this application is provided below, along with the accompanying drawings and specific implementations. Note that when an element is described as “attached” to another element, it may be directly on the other element or there may be one or more intervening elements between them. When one element is described as “connected” to another element, it may be directly connected to the other element or there may be one or more intervening elements between them. As used herein, terms such as “top,” “bottom,” “left,” “right,” “inside,” and “outside” are for illustrative purposes only.

[0079] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art relating to this application. Terms used in the specifications of this application are for the sole purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any combination of one or more of the related enumerated items.

[0080] As shown in Figures 1 and 2, the aerosol generator 100 comprises an atomizer 10 and a power supply assembly 20.

[0081] The atomizer 10 is detachably or removably connected to the power supply assembly 20, including but not limited to snap-on, magnetic, or screw connections.

[0082] In a preferred embodiment, the outer surface of the atomizer 10 is provided with protrusions, and the inner surface of the power supply assembly 20 is provided with grooves. The snap-on connection between the atomizer 10 and the power supply assembly 20 is achieved through the engagement of the protrusions and grooves.

[0083] The power supply assembly 20 comprises a battery core, a circuit, and a magnetic field generator.

[0084] The battery core provides the power necessary to operate the aerosol generator 100. The battery core may be a rechargeable battery core or a disposable battery core.

[0085] The circuit can control the overall operation of the aerosol generator 100. The circuit controls not only the operation of the battery core and the magnetic field generator, but also the operation of other elements within the aerosol generator 100. The circuit comprises at least one processor. The processor may comprise a logic gate array, or a combination of a general-purpose microprocessor and memory for storing programs executable within the microprocessor. Furthermore, those skilled in the art should understand that the circuit may comprise other types of hardware.

[0086] The magnetic field generator generates a magnetic field that changes under alternating current, and the magnetic field generator includes, but is not limited to, an induction coil. The magnetic field generator is electrically connected to the battery core. The magnetic field generated by the magnetic field generator has the ability to substantially enclose the atomizing core 132, and therefore the coupling distance between the susceptor layer 132b of the atomizing core 132 and the magnetic field generator is reduced, which can improve the heating efficiency of the atomizer 10. In a preferred embodiment, the atomizing core 132 is coaxial with the magnetic field generator, and both extend along the axial direction of the aerosol generator 100, which is advantageous for improving the heating efficiency of the atomizer 10.

[0087] As shown in Figures 3 and 4, the atomizer 10 comprises an upper housing 11, a sealing element 12, an atomizing assembly 13, a sealing element 14, and a base 15.

Inside the upper housing 11 is also a integrally molded transfer tube 11a used to guide the aerosol to the suction nozzle. The upper end of the transfer tube 11a is connected to the suction nozzle, and its lower end extends into the atomizing assembly 13. In another embodiment, it is also feasible for the transfer tube 11a to be formed from a separate hollow tube.

[0089] Liquid storage cavity A is used to store a liquid substrate capable of generating an aerosol. Liquid storage cavity A is at least partially defined by the inner surface of the upper housing 11, the outer surface of the atomizing assembly 13, and the inner surface of the base 15.

[0090] The liquid base preferably contains a tobacco-containing material, which includes volatile tobacco-flavored compounds released from the liquid base upon heating. Alternatively, or additionally, the liquid base may contain non-tobacco materials. The liquid base may contain water, ethanol, or other solvents, plant extracts, nicotine solutions, and natural or artificial flavors. The liquid base preferably further contains an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerin and propylene glycol.

[0091] The sealing element 12 is positioned between the transmission tube 11a and the atomizing assembly 13, between the atomizing assembly 13 and the base 15, and between the base 15 and the upper housing 11 to seal the gap between the transmission tube 11a and the atomizing assembly 13, the gap between the atomizing assembly 13 and the base 15, and the gap between the base 15 and the upper housing 11. The sealing element 12 is made of a flexible material such as silicone. In another embodiment, the sealing element 12 may comprise a plurality of separate sealing elements, for example, one sealing element positioned between the transmission tube 11a and the atomizing assembly 13, and another sealing element positioned between the base 15 and the upper housing 11. In another embodiment, the sealing element 12 may be integrally molded with the base 15 (or upper housing 11), for example by two-color injection molding. In another embodiment, the sealing element 12 may not be provided.

[0092] In further embodiments, pressure balancing channels may be provided within the sealing element 12 and / or between the sealing element 12 and the transfer tube 11a and / or between the sealing element 12 and the upper housing 11, between the transfer tube 11a and the atomizing assembly 13 and / or between the base 15 and the upper housing 11, to replenish the liquid storage cavity A with gas, thereby balancing the internal and external air pressure of the liquid storage cavity A and facilitating the transfer of the liquid substrate.

[0093] As shown in Figure 5, the atomizing assembly 13 comprises a bracket 131, an atomizing core 132, a heat insulating element 133, and a retaining element 134.

[0094] The bracket 131 is configured as a tubular structure having openings at both ends, and its cross-section may be circular, elliptical, square, racetrack-shaped, annular, or any other shape. The upper end of the bracket 131 extends toward the direction of the transmission pipe 11a, and the lower end of the transmission pipe 11a extends into the bracket 131 through the opening at the upper end of the bracket 131. The lower end of the bracket 131 is housed or held within the second connecting portion 152 of the base 15, and the opening at the lower end of the bracket 131 is connected to the air intake port 152b.

[0095] In a further embodiment, the bracket 131 has a positioning portion 131a that extends radially outward near its upper outer surface, and the inner surface of the first connecting portion 151 of the base 15 has a positioning post 151a. Assembly of the bracket 131 to the base 15 is facilitated by the fitting of the positioning portion 131a and the positioning post 151a.

[0096] In a further embodiment, the support portion 152a is provided within a second connecting portion 152 of the base 15, and the lower end of the bracket 131 abuts against the support portion 152a. In this way, when the bracket 131 is assembled within the base 15, the bracket 131 can be supported by the support portion 152a. In a preferred embodiment, the support portion 152a comprises a plurality of projections with gaps between them, extending in the longitudinal direction and projecting from the inner surface of the second connecting portion 152.

[0097] The opening 131b is provided on the side wall of the bracket 131. The hollow interior of the bracket 131 forms a receiving cavity connected to the opening 131b and an airflow channel connected to the receiving cavity. As can be seen from Figure 4, the portion of the liquid storage cavity A, the receiving cavity, and the airflow channel defined between the inner surface of the second connecting portion 152 and the outer surface of the bracket 131 are arranged continuously along the width direction of the atomizer 10 or aerosol generator 100. The portion of the liquid storage cavity A and the airflow channel are located on both sides of the atomizing core 132, with the liquid-absorbing surface 132a2 of the porous body 132a defining the boundary of the portion of the liquid storage cavity A, and the atomizing surface 132a1 of the porous body 132a defining the boundary of the airflow channel. In this way, the volume of the liquid storage cavity A is increased on the one hand, and the liquid substrate may be smoothly delivered to the atomizing core 132 on the other hand. Air flows into the bracket 131 through the opening at the lower end, passes through the airflow channel, exits through the opening at the upper end of the bracket 131, and enters the transmission pipe 11a.

[0098] As shown in Figures 6 and 7, the atomizing core 132 includes a porous body 132a and a susceptor layer 132b bonded to the surface of the porous body 132a.

[0099] The porous body 132a is used to draw out the liquid substrate from the liquid storage cavity A and deliver the drawn-out liquid substrate to the susceptor layer 132b. The porous body 132a can be made from a rigid capillary structure such as porous ceramic, porous glass ceramic, or porous glass. The shape of the porous body 132a is configured as a plate-like structure in which the atomizing surface 132a1 and the liquid absorption surface 132a2 are arranged relative to each other, and both the atomizing surface 132a1 and the liquid absorption surface 132a2 are flat and planar, with the liquid absorption surface 132a2 facing the opening 131b and the atomizing surface 132a1 facing the airflow channel.

[0100] In one embodiment, the porous body 132a comprises a plurality of regular through-holes 132a3 extending from the liquid-absorbing surface 132a2 to the atomizing surface 132a1. The plurality of through-holes 132a3 may be formed by etching or a similar method. The plurality of through-holes 132a3 may be arranged in an array, connected to each other, or not connected. The openings of the through-holes 132a3 are 0.1 μm to 100 μm, preferably 1 μm to 100 μm, preferably 2 μm to 100 μm, preferably 5 μm to 100 μm, preferably 5 μm to 80 μm, preferably 5 μm to 60 μm, preferably 5 μm to 40 μm, and preferably 5 μm to 20 μm.

[0101] In one embodiment, the porous body 132a includes a plurality of irregular through-holes extending from the liquid absorption surface 132a2 to the atomizing surface 132a1. These irregular through-holes are determined by the material of the porous body 132a. As above, the openings of the irregular through-holes are 0.1 μm to 100 μm, preferably 1 μm to 100 μm, preferably 2 μm to 100 μm, preferably 5 μm to 100 μm, preferably 5 μm to 80 μm, preferably 5 μm to 60 μm, preferably 5 μm to 40 μm, and preferably 5 μm to 20 μm. The porosity is in the range of 30% to 60%.

[0102] The porous body 132a is assembled within the bracket 131 through the opening 131b and housed in the receiving cavity. The porous body 132a is positioned to be mounted along the long axis of the bracket 131. The liquid-absorbing surface 132a2 of the porous body 132a is fluidly connected to the liquid storage cavity A, and the liquid-absorbing surface 132a2 is used to receive the liquid substrate from the liquid storage cavity A, with at least a portion of the airflow channel defined between the atomizing surface 132a1 of the porous body 132a and the inner surface of the bracket 131.

[0103] The susceptor layer 132b is inductively coupled to a magnetic field generator and is configured to generate heat as it penetrates due to the changing magnetic field, thereby heating the liquid substrate and generating an aerosol for inhalation. The susceptor layer 132b may be made of at least one of the following materials: aluminum, iron, nickel, copper, bronze, cobalt, ordinary carbon steel, stainless steel, ferritic stainless steel, martensitic stainless steel, or austenitic stainless steel. As an example of a method for preparing the susceptor layer 132b, the raw material powder for preparing the susceptor layer 132b is mixed with a printing aid to form a paste, which is then combined with the atomizing surface 132a1 of the porous body 132a after printing, and subsequently sintered so that the entire surface or most of it is closely bonded to the atomizing surface 132a1 of the porous body 132a. This method results in high atomization efficiency, minimizes heat loss, prevents dry combustion, or significantly reduces the effects of dry combustion. Naturally, the bonding of the susceptor layer 132b to the atomizing surface 132a1 of the porous body 132a is not limited to the method described above, and can also be achieved by methods such as vapor deposition or etching. Furthermore, it can be achieved by bonding a thin metal sheet to the atomizing surface 132a1 of the porous body 132a and sintering it.

[0104] The susceptor layer 132b covers only a portion of the atomizing surface 132a1 of the porous body 132a. There is a gap between the susceptor layer 132b and the periphery of the atomizing surface 132a1. In this way, after the porous body 132a is installed, the susceptor layer 132b may be kept out of contact with the bracket 131 or the insulating element 133, which reduces heat loss and also reduces material selection requirements (e.g., temperature resistance requirements) for components such as the bracket 131 or the insulating element 133. Furthermore, the area of ​​the atomizing surface 132a1 of the porous body 132a near the periphery that is not covered by the susceptor layer 132b may be provided with a position for mating with the insulating element 133.

[0105] As shown in Figure 8, the width dimensions of the upper and lower ends of the susceptor layer 132b are greater than the width dimension of the middle portion of the susceptor layer 132b. Specifically, the width dimension of the upper end of the susceptor layer 132b is d1, the width dimension of the middle portion of the susceptor layer 132b is d2, and the width dimension of the lower end of the susceptor layer 132b is d3, with both d1 and d3 being greater than d2. In a preferred embodiment, d1 and d3 are the same dimension. The dimension of d2 is one-third to two-thirds of the dimension of d1 (or d3), and a preferred dimension of d2 is half the dimension of d1 (or d3). The dimension of d2 is 0.1 mm to 5 mm, preferably 0.1 mm to 4 mm, preferably 0.1 mm to 2 mm, preferably 0.5 mm to 2 mm, and in certain examples it may be 0.7 mm. The length dimension of the susceptor layer is 1 mm to 15 mm, preferably 1 mm to 12 mm, preferably 1 mm to 10 mm, preferably 2 mm to 10 mm, and in certain embodiments it may be 6 mm. The thickness of the susceptor layer 132b is 0.02 mm to 0.15 mm, preferably 0.02 mm to 0.12 mm, preferably 0.02 mm to 0.1 mm, preferably 0.04 mm to 0.1 mm, preferably 0.06 mm to 0.1 mm.

[0106] As can be seen in Figure 8, the side surface of the susceptor layer 132b is substantially arched along the extension direction from the upper end to the lower end of the susceptor layer 132b. The susceptor layer 132b has a first surface that is in contact with the atomizing surface 132a1 of the porous body 132a (i.e., extends flatly over the atomizing surface 132a1) and a second surface that is opposite to the first surface (facing away from the atomizing surface 132a1 of the porous body 132a). Both surfaces are continuous surfaces, meaning they are complete surfaces without interruption or grooves or holes.

[0107] On the other hand, this shape of the susceptor layer 132b makes it easier for magnetic field lines to concentrate in the middle portion of the susceptor layer 132b, thereby improving the current density in this portion. During operation, the current density in the middle portion of the susceptor layer 132b is greater than that at the two ends, and the temperature rise in the middle portion is faster than at the two ends. This causes the heat generated by the susceptor layer 132b to become more concentrated, making it easier to reduce the energy required for the susceptor layer 132b to reach the desired atomization temperature. On the other hand, this irregular shape of the susceptor layer 132b helps to reduce its volume and mass, which reduces the energy required for the susceptor layer 132b to reach the atomization temperature and improves atomization efficiency.

[0108] Referring again to Figures 9 and 10, in another embodiment, the periphery of the susceptor layer 132b has one or more outward-extending protrusions, such as the illustrated protrusions 132b1 and 132b2, where protrusion 132b1 extends along the length direction of the porous body 132a and protrusion 132b2 extends along the width direction of the porous body 132a. Protrusions 132b1 and 132b2 promote heat transfer and increase the atomization area.

[0109] The thermal insulation element 133 is housed within a receiving cavity. At least a portion of the thermal insulation element 133 is positioned between the bracket 131 and the porous body 132a to separate the bracket 131 from the porous body 132a, thereby avoiding excessive heat transfer from the atomizing core 132 to the bracket 131, and thus avoiding the problem of heat loss. The thermal insulation element 133 may be made of a flexible material such as heat-resistant silicone so that the gap between the inner surface of the bracket 131 and the porous body 132a can be sealed by the flexible sealing properties of silicone.

[0110] The thermal insulation element 133 is configured to hold or support the porous body 132a within a receiving cavity. In a preferred embodiment, the thermal insulation element 133 is configured to have a cavity structure with openings at both ends, where the opening at one end of the thermal insulation element 133 is connected to an opening 131b, and the opening at the other end of the thermal insulation element 133 is connected to an airflow channel. The porous body 132a is housed within the hollow portion 133a of the thermal insulation element 133. The end of the thermal insulation element 133 adjacent to the airflow channel also has a limiting portion 133b that abuts against a portion of the atomizing surface 132a1 of the porous body 132a, restricting the movement of the porous body 132a toward the airflow channel.

[0111] The retaining element 134 is positioned in the opening 131b. The retaining element 134 is configured in the shape of a racetrack around the through-hole, through which the liquid substrate stored in the liquid storage cavity A may flow onto the liquid-absorbing surface 132a2 of the porous body 132a. The retaining element 134 comprises a body 134a, a projection 134b positioned on the body 134a, and a crossbeam 134c. The body 134a is assembled within the bracket 131 through the opening 131b and abuts against a portion of the liquid-absorbing surface 132a2 of the porous body 132a, and the projection 134b is exposed on the side wall of the bracket 131 and protrudes along the width or length of the body 134a and abuts against the side wall of the bracket 131. The porous body 132a may be held within the insulating element 133 by the retaining element 134. The crossbeam 134c extends across the body 134a and reinforces its strength. As can be seen from the diagram, the two crossbeams 134c divide the through-hole of the retaining element 134 into three smaller through-holes across the main body 134a.

[0112] During assembly, the porous body 132a may first be assembled on the thermal insulation element 133 to form a single module, and then the module may be assembled into the bracket 131 through the opening 131b. Finally, the retaining element 134 is assembled on the bracket 131. Once assembled, the projection 134b of the retaining element 134 is exposed on the side wall of the bracket 131 and abuts against the side wall of the bracket 131.

[0113] As shown by R1 in the figure, the liquid substrate stored in the liquid storage cavity A flows through the through-hole of the retaining element 134 into the porous body 132a, is drawn out by the liquid-absorbing surface 132a2 of the porous body 132a, delivered toward the atomizing surface 132a1 of the porous body 132a, and then atomized by the susceptor layer 132b to generate an aerosol. The aerosol generated by the atomization of the susceptor layer 132b can flow through the opening at the other end of the insulating element 133 into the bracket 131 or airflow channel. The aerosol mixes with the outside air and, as shown by R2 in the figure, flows together into the transfer tube 11a and can be inhaled by the user or inhaler through the suction nozzle.

[0114] The sealing element 14 is used to seal the gap between the bracket 131 and the second connecting portion 152 of the base 15. Similar to the sealing element 12, the sealing element 14 is made of a flexible material such as silicone. Other structural designs may refer to the sealing element 12.

[0115] As shown in Figures 11 and 12, the base 15 and the upper housing 11 form the housing assembly of the atomizer 10. The base 15 includes a first connecting portion 151 and a second connecting portion 152 that are integrally molded. In other embodiments, the first connecting portion 151 and the second connecting portion 152 can be formed separately.

[0116] The first connecting portion 151 is housed within the upper housing 11, and the cross-section of the first connecting portion 151 is substantially elliptical in shape. The area of ​​the upper end opening of the first connecting portion 151 is larger than the area of ​​its lower end opening, and the lower end opening is adjacent to the second connecting portion 152 or has a defining upper end opening of the second connecting portion 152.

[0117] In a preferred embodiment, a projection 151b is provided on the outer surface of the first connecting portion 151, and a groove (not shown) is provided on the inner surface of the upper housing 11, and the snap-on connection between the first connecting portion 151 and the upper housing 11 is achieved by engaging the projection 151b with the groove.

[0118] In a preferred embodiment, the lower end of the first connecting portion 151 has a support portion 151c that extends radially outward to support the end of the open end of the upper housing 11. The outer surface of the first connecting portion 151 adjacent to the upper end also has a step 151d that holds a portion of the sealing element 12.

[0119] The second connecting portion 152 is exposed to the outside of the upper housing 11 or the atomizer 10. In this way, the upper housing 11 forms the first part of the housing assembly of the atomizer 10, and the second connecting portion 152 forms the second part of the housing assembly of the atomizer 10. The second part is housed within the power supply assembly. The radial dimension of the second part is smaller than that of the first part.

[0120] The second connecting portion 152 is configured in the shape of a sleeve having a radial dimension of 9 mm or less. The radial dimension of the second connecting portion 152 is smaller than the radial dimension of the first connecting portion 151. For example, the cross-sectional width dimension of the second connecting portion 152 is smaller than the width dimension of the first connecting portion 151, or the cross-sectional length dimension of the second connecting portion 152 is smaller than the cross-sectional length dimension of the first connecting portion 151, or the cross-sectional area of ​​the first connecting portion 151 is larger than the cross-sectional area of ​​the second connecting portion 152, and the length dimension of the second connecting portion 152 along the long axis is larger than the length dimension of the first connecting portion 151.

[0121] In a preferred embodiment, the cross-section of the second connecting portion 152 is elliptical, and the radial dimension of the second connecting portion 152 is either the major axis or the minor axis of the ellipse. The difference between the major axis and the minor axis of the second connecting portion 152 is 0.5 mm to 2 mm (preferably 0.5 mm to 1.5 mm, more preferably 0.5 mm to 1 mm). Specifically, the length of the major axis d1 of the ellipse is 8 mm to 9 mm (preferably 8 mm to 8.8 mm, more preferably 8 mm to 8.6 mm, more preferably 8.2 mm to 8.6 mm, more preferably 8.4 mm to 8.6 mm), and the length of the minor axis of the ellipse is 6 mm to 8 mm (preferably 7 mm to 8 mm, more preferably 7.2 mm to 8 mm, more preferably 7.4 mm to 8 mm, more preferably 7.6 mm to 8 mm, more preferably 7.6 mm to 7.8 mm). In a particular embodiment, the length of the major axis d1 is 8.5 mm, and the length of the minor axis d2 is 7.7 mm.

[0122] In other embodiments, the cross-section of the second connecting portion 152 may also be circular. The radial dimension of the second connecting portion 152 is the diameter of the circle.

[0123] An air intake port 152b is provided at the bottom end of the second connection portion 152, and the wall forming the air intake port 152b protrudes from the bottom end of the second connection portion 152, thereby preventing the liquid substrate collected in the collection cavity 152c from flowing directly through the air intake port 152b to the power supply assembly 20. External air flows through the air intake port 152b, then sequentially passes through the sealing element 14, the bracket 131, and the transfer tube 11a, and finally exits through the air outlet of the upper housing 11.

[0124] As shown in Figure 13, in another embodiment, a one-way valve 16 is positioned above the air intake port 152b. When the atomizer 10 is drawn in, airflow enters through the air intake port 152b and the one-way valve 16 opens. When the atomizer 10 is not drawn in, there is no airflow through the air intake channel, and the one-way valve 16 closes, isolating the air intake channel and preventing the liquid substrate or atomized aerosol from flowing out of the air intake port 152b.

[0125] Figures 14-19 are schematic diagrams of atomizer 10' according to an alternative embodiment. As shown in Figure 19, atomizer 10' according to the alternative embodiment may be used with the power supply assembly 20' in the same manner as atomizer 10 in the embodiments of Figures 1-13. The general operating principle of atomizer 10' according to the embodiments of Figures 14-19 is similar to the operating principle of atomizer 10 described above.

[0126] As shown in Figure 14, the atomizer 10' extends along the long axis 100 from the air intake end 110 to the mouthpiece end 120. At the mouthpiece end 120, the atomizer 10' is equipped with a suction nozzle or air outlet 130 through which atomized aerosol is delivered to the user. At the air intake end 110, the atomizer 10' has an air intake port 152b. At the air intake end 110, the atomizer 10' may be connected to the power supply assembly 20'.

[0127] The atomizer 10' comprises a proximal portion 140 and a distal portion 150. The proximal portion 140 includes a mouthpiece end 120, and the distal portion 150 includes an air intake end 110. The proximal portion 140 is located downstream of the distal portion 150 with respect to the long axis 100, from the air intake end toward the mouthpiece end.

[0128] As shown in Figures 16 and 17, the atomizer 10' comprises an upper housing 11, a proximal sealing element 12, an atomizing assembly 13, a distal sealing element 14, and a base 15.

[0129] The base 15 defines an air intake end 110, which is provided with an air intake port 152b. The upper housing 11 defines a mouthpiece end 120, which is provided with an air outlet 130.

[0130] The upper housing 11 includes a transfer tube structure 11a for guiding an aerosol to a suction nozzle or air outlet 130 provided at the air outlet end 120. The liquid storage cavity A extends circumferentially around the transfer tube structure 11a for storing a liquid substrate. In the illustrated embodiment, the transfer tube structure 11a is an integral part of the upper housing 11, but alternatively, the transfer tube structure 11a may be provided as a separate part.

[0131] As shown in more detail in Figure 18, the atomizing assembly 13 comprises a bracket 131, an atomizing core 132, a heat insulating element 133, and a retaining element 134.

[0132] Bracket 131 is a tubular structure that defines an airflow channel passing through it. The airflow channel extends along the longitudinal axis 100. Bracket 131 has a bracket air intake 1312 at its upstream end and a bracket air outlet 1313 at its downstream end. The airflow channel connects the bracket air intake 1312 and the bracket air outlet 1323. The downstream end of bracket 131 and the bracket air outlet 1313 are connected to or fluidly communicate with the transmission tubular structure 11a. The upstream longitudinal ends of bracket 131 and bracket air intake 1312 are fluidly communicating with the air intake 152b of the base 15.

[0133] The atomizing core 132 comprises a main body 132a and a susceptor layer 132b. The main body 132a may have a wicking function for supplying liquid from the liquid storage cavity A to the susceptor layer 132b. The main body 132a may be permeable to the liquid substrate. The main body 132a may be porous. The main body 132a may contain a ceramic material. The main body 132a may contain a fibrous material such as cotton.

[0134] The susceptor layer 132b is configured to be inductively heated by exposure to an alternating magnetic field, thereby heating the liquid substrate and generating an aerosol. The susceptor layer 132b may contain a metallic material. The metallic material may include steel or stainless steel, particularly SUS430. The susceptor layer 132b may have one or more openings or through holes. The susceptor layer 132b may have a mesh shape.

[0135] The main body 132a has an atomizing surface 132a1 and a liquid-absorbing surface 132a2 opposite to the atomizing surface 132a1. The main body 132a is configured to draw liquid at the liquid-absorbing surface 132a2 and deliver the drawn liquid to the susceptor layer 132b via the atomizing surface 132a1. Both the atomizing surface 132a1 and the liquid-absorbing surface 132a2 are flat and planar and extend parallel to each other. The susceptor layer 132b is provided on the atomizing surface 132a1 of the main body 132a. The susceptor layer 132b may be a separate element from the main body 132a or it may be integrated with the main body 132a.

[0136] The opening 131b is provided in the lateral side wall of the bracket 131. The hollow interior of the bracket 131 forms a receiving cavity connected to the opening 131b and an airflow channel connected to the receiving cavity. The atomizing core 132 and the insulating element 133 are housed within the receiving cavity of the bracket 131. The atomizing surface 132a1 and the susceptor 132b face inward from the bracket 131, and therefore toward the airflow channel. The liquid absorption surface 132a2 faces outward from the bracket 131, and therefore away from the airflow channel and toward the outlet of the liquid supply channel 151 (see Figure 17).

[0137] The thermal insulation element 133 is at least partially positioned between the bracket 131 and the main body 132a and / or the susceptor layer 132b to separate the bracket 131 from the main body 132a and / or the susceptor layer 132b, thereby avoiding excessive heat transfer from the atomizing core 132 to the bracket 131. The thermal insulation element 133 may include, for example, high-temperature silicone, cotton material, or ceramic material. The thermal insulation element 133 may have a frame shape. The thermal insulation element 133 may be a porous element. The thermal insulation element 133 may be a fibrous element such as cotton, saturated with liquid from the liquid storage cavity A, and acting as a heat buffer to minimize heat transfer from the susceptor layer 132b to the bracket 131. The shape of the thermal insulation element 133 may be frame-like or may match the outer contour of the susceptor 132b.

[0138] The retaining element 134 is positioned in the opening 131b of the bracket 131. The retaining element 134 holds the atomizing core 132 and the heat insulating element to the bracket 131. The retaining element 134 has one or more openings through which the liquid substrate from the liquid storage cavity A may flow onto the liquid absorption surface 132a2 of the main body 132a, or otherwise be absorbed thereby.

[0139] Figure 17 shows two liquid channels R1 leading from the liquid storage cavity A to the atomizing core 132. Alternatively, only one liquid channel R1 or three or more liquid channels R1 may be provided. The liquid channels R1 extend through liquid supply channels 151. Each liquid supply channel 151 opens into the liquid storage cavity A through a separate opening 153. The liquid channels R1 from both liquid supply channels 151 may be supplied at least partially coupled to the liquid absorption surface 132a2 of the body 132a through an opening in the retaining element 134 so that the liquid substrate is supplied to the susceptor layer 132b for vaporization.

[0140] In the susceptor layer 132b, the liquid substrate is vaporized and mixed with air flowing along the airflow path R2 that extends from the air intake port 152b of the base 15 through the internal space of the bracket 131. Here, the air mixes with the vaporized liquid to form an aerosol, which is then sent through the transfer tube 11a to the air outlet 130.

[0141] Figure 19 shows an atomizer 10' connected to a power supply assembly 20'. The atomizer 10' and the power supply assembly 20' together form an atomizing system. The power supply assembly 20' has a receiving cavity 200 that receives the distal portion 150 of the atomizer 10' when the atomizer 10' is connected to the power supply assembly 20'. The distal portion 150 of the atomizer 10' is inserted into the receiving cavity 200 against the longitudinal axis 100. The proximal portion 140 of the atomizer 10' may remain completely or partially outside the receiving cavity 200 and / or outside the power supply assembly 20' when the atomizer 10' is connected to the power supply assembly 20'.

[0142] The distal portion 150 of the atomizer 10' has a tubular shape extending along the long axis 100. The distal portion 150 may also be cylindrical. The atomizing core 132 may extend through the central axis in the long axis direction of the distal portion 150. The susceptor layer 132b or the main body 132a may extend through the central axis in the long axis direction of the distal portion 150.

[0143] The receiving cavity 200 has a cylindrical shape corresponding to the shape of the distal portion 150. The inductor coil 201 of the power supply assembly 20' extends concentrically around the receiving cavity 200. The inductor coil 201 extends along the long axis 100. When the atomizer 10' is connected to the power supply assembly 20', the inductor coil 201 may be powered by the battery 203 of the power supply assembly 20' to generate a changing magnetic field. The changing magnetic field penetrates the susceptor layer 132b provided within the receiving cavity 200, thereby inducing a current within the susceptor layer 132b, which heats the susceptor layer 132b, and thereby heats the liquid substrate provided to the susceptor layer 132b via the atomizing surface 132a1 of the body 132a.

[0144] The cylindrical shape of the distal portion 150 of the atomizer 10' facilitates the positioning of the susceptor layer 132b in the center of the receiving cavity 200 or in the center of the induction coil 201, which can increase the efficiency of heating.

[0145] The atomizing core 132 and / or susceptor layer 132b may be positioned centrally within the induction coil 201 along the longitudinal axis 100 when the atomizer 10' is connected to the power supply assembly 20'. This may increase the efficiency of heating. Alternatively, the atomizing core 132, and in particular the susceptor layer 132b, may be offset along the longitudinal axis 100 with respect to the longitudinal center of the induction coil 201, as shown in Figure 19. The atomizing core 132 may be positioned centrally within the induction coil 201 with respect to the lateral direction. The susceptor layer 132b may be positioned centrally within the induction coil 201 with respect to the lateral direction.

[0146] The proximal portion 140 of the atomizer 10' may have an elliptical or elliptical cross-section in the cross-sectional plane, perpendicular to the long axis 100 and gradually tapering from the distal engaging end to the proximal mouthpiece end, as shown in Figure 14. Each elliptical or elliptical cross-section has an elliptical minor axis 101 and a long axis 103, as shown in Figure 17.

[0147] As shown in Figure 17, the main expansion plane of the atomizing core 132, particularly the main expansion plane of the body 132a and / or the main expansion plane of the susceptor layer 132b, is preferably parallel to the longitudinal axis 100 and the longitudinal axis 103. The atomizing surface 132a1 and the liquid absorption surface 132a2 of the body 132a, or both, are preferably parallel to the longitudinal axis 100 and the longitudinal axis 103.

[0148] As can be seen in Figures 14 and 15, for example, the cross-section of the proximal portion 140 of the atomizer 10' is larger than the cross-section of the distal portion 150 of the atomizer 10'. The atomizer 10' may have a general mushroom shape, with the proximal portion 140 generally corresponding to the cap portion of the mushroom and the distal portion 150 generally corresponding to the stem portion of the mushroom.

[0149] The diameter of the atomizer 10' may decrease smoothly, gradually, or in steps with respect to the longitudinal axis 100 where the proximal portion 140 intersects the distal portion 150. In the illustrated embodiment, the stepped portion 145 is provided along the longitudinal axis 100 between the distal portion 150 and the proximal portion 140 of the atomizer 10'. In the stepped portion 145, the diameter of the atomizer 10' increases in steps from the distal portion 150 to the proximal portion 140. Since the distal portion 150 of the atomizer 10' houses the atomizing core 132, the reduced diameter of the distal portion 150 may allow for a smaller distance between the atomizing core 132, particularly the susceptor layer 132b, and the induction coil 201 when the atomizer 10' is connected to the power supply assembly 20', thereby potentially increasing heating efficiency.

[0150] The ratio of the maximum lateral extension of the proximal portion 140 along the long axis 103 to the maximum lateral extension of the distal portion 150 of the atomizer 10' may be at least 1.4, or at least 1.6, or at least 1.8, or at least 2, or at least 2.2, or at least 2.4, or at least 2.6, or at least 3, or at least 4.

[0151] As best seen in Figures 15 and 19, the lower end surface 147 of the proximal portion 140 of the atomizer 10' generally faces against the longitudinal axis 100 or toward the distal portion 150, and may be inclined with respect to a plane perpendicular to the longitudinal axis 100. The lower end surface 147 may form a stepped portion 145, or be part of a stepped portion 145. As shown in Figure 18, the downstream end surface of the bracket 131 facing along the longitudinal axis 100 may be inclined with respect to a plane perpendicular to the longitudinal axis 100, in particular in the same manner as the lower end surface 147 of the proximal portion 140 of the atomizer 10'. The power supply assembly 20' may have an upper end surface 149 generally facing the longitudinal axis 100. The upper end surface 149 may be inclined with respect to a plane perpendicular to the longitudinal axis 100. The upper end surface 149 may be inclined with respect to a plane perpendicular to the longitudinal axis 100 in a manner complementary to the lower end surface 147 of the atomizer 10'. The angle between the lower end surface 147 of the atomizer 10' and the plane perpendicular to the longitudinal axis 100 may be the same as the angle between the upper end surface 149 of the power supply assembly 20' and the plane perpendicular to the longitudinal axis 100. When the atomizer 10' is combined with the power supply assembly 20', the lower end surface 147 of the atomizer 10' and the upper end surface 149 of the power supply assembly 20' may face each other. When the atomizer 10' is combined with or engaged with the power supply assembly 20', the lower end surface 147 of the atomizer 10' and the upper end surface 149 of the power supply assembly 20' interact to ensure the correct relative rotation angle between the atomizer 10' and the power supply assembly 20' with respect to rotation around an axis extending along the longitudinal axis 100.

[0152] The atomizer 10' may include an indicator ring 180. The indicator ring 180 may be provided on the proximal portion 140 of the atomizer 10'. The indicator ring 180 may extend completely around the central axis of the atomizer 10' parallel to the longitudinal axis 100. The indicator ring 180 may be parallel to the lower end surface 147 of the proximal portion 140 of the atomizer 10'. The indicator ring 180 may form part of the outer surface of the atomizer 10'. The indicator ring 180 may have a different color from the rest of the outer surface of the atomizer 10', in particular a different color from the upper housing 11. The indicator ring 180 may be configured to indicate characteristics of the atomizer 10', such as the flavor or type of liquid in the liquid storage cavity A. The color of the indicator ring 180 may indicate characteristics of the atomizer 10', such as the flavor or type of liquid in the liquid storage cavity A.

[0153] As shown in Figure 18, the bracket 1312 has a circumferential groove 1320 at its upstream end, which serves as a seat for the distal sealing element 14. The distal sealing element 14 has an annular shape and contacts the bracket 131 and the base 15, particularly the inner wall surface of the base 15, to prevent or reduce leakage of the liquid substrate.

[0154] Figures 20-22 show brackets 131' and distal sealing elements 14' according to alternative embodiments. Brackets 131' and distal sealing elements 14' according to alternative embodiments may be used, for example, in place of brackets 131 and distal sealing elements 14 in atomizer 10'. The general design and function of brackets 131' and distal sealing elements 14' correspond to the general design and function of brackets 131 and distal sealing elements 14. Embodiments of brackets 131' and distal sealing elements 14' that are the same as brackets 131 and distal sealing elements 14 will not be described in detail.

[0155] Similar to bracket 131, bracket 131' has a bracket air intake 1312 at the upstream end of bracket 131 and a bracket air outlet 1313 at the downstream end of bracket 131, with the bracket air intake 1312 and bracket air outlet 1323 connected by an airflow channel. Instead of a circumferential groove 1320, bracket 131' has a planar circumferential surface 1315 as a sheet of distal sealing element 14'. The planar circumferential surface 1315 can facilitate the manufacture or assembly of atomizer 10', particularly the manufacture or assembly of atomizer 10' by an automated method. The distal sealing element 14' has an annular shape and is in circumferential contact with the planar circumferential surface 1315 of bracket 131' and the base 15, particularly the inner wall surface of the base 15, to prevent or reduce leakage of the liquid substrate.

[0156] As shown in Figure 21, the distal sealing element 14' has at least one circumferential sealing lip portion 1320 that extends radially outward and engages with the inner surface of the base 15. In the illustrated embodiment, the sealing lip portion 1320 comprises two sealing lip portions 1320 spaced apart along the longitudinal axis 100. At least one sealing lip portion 1320 is asymmetric with respect to any plane perpendicular to the longitudinal axis 100. At least one sealing lip portion 1320 is shaped such that it resists bending along the longitudinal axis 100 more than bending against the longitudinal axis 100. At least one sealing lip portion 1320 is elastically pressed against the inner surface of the base 15 and is shaped to seal the space between the bracket 131 and the base 15.

[0157] The distal sealing element 14' has a planar inner surface 1325 that contacts the planar circumferential surface 1315 of the bracket 131'. The flange 1327 extends radially inward from the planar inner surface 1325. The flange 1327 engages with and at least partially covers the end face 1329 of the bracket 131', which is oriented in the opposite direction to the long axis 100.

[0158] Figure 22 shows a cross-sectional view of the bracket 131' as seen in a cross-sectional plane perpendicular to the long axis 100 and in the viewing direction from the bracket air outlet 1313 to the bracket air intake 1312. The bracket air intake 1312 has an opening 1330 through which air passes and enters the airflow channel. In the illustrated embodiment, the opening 1330 has a circular cross-section, but other shapes are possible, such as an elliptical cross-section, a rectangular cross-section, or an irregular cross-section. The diameter of the opening 1330 may be less than 5 millimeters, or less than 2 millimeters, or less than 1 millimeter. The diameter of the opening 1330 may be, for example, 0.3 millimeters to 1 millimeter, or 0.5 millimeters to 1 millimeter. The opening cross-section of the opening may be, for example, less than 1 square millimeter, or less than 0.5 square millimeters. The opening cross-section of the opening may be, for example, 0.2 square millimeters to 1 square millimeter, or 0.2 square millimeters to 0.5 square millimeters. The small opening 1330 can, for example, reduce leakage of the liquid substrate during transport and storage, while allowing sufficient air passage during the user experience.
