[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terms used herein are for the purpose of describing specific embodiments only and are not intended to be limiting of this application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0015] As shown in FIGS. 1 and 2, the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20.

[0016] The atomizer 10 is removably or detachably connected to the power assembly 20, including but not limited to mating, magnetic, and threaded connections.

[0017] In a preferred embodiment, the atomizer 10 has a protrusion on its outer surface and a groove on its inner surface, and the atomizer 10 and the power assembly 20 are mated with each other to achieve an engagement between them.

[0018] As shown in FIGS. 3 and 4, the atomizer 10 includes an upper housing 11, a sealing member 12, an atomizing assembly 13, a sealing member 14, and a holder 15.

[0019] The upper housing 11 has a mouth end and an open end. A mouthpiece or exhaust port is provided at the mouth end, and the atomized aerosol can be inhaled by the user or smoker through the mouthpiece. The upper housing 11 further has an integrally formed transport tube 11a for guiding the aerosol to the mouthpiece, with the upper end of the transport tube 11a communicating with the mouthpiece and the lower end inserted into the atomization assembly 13. In another example, the transport tube 11a may be formed as a single hollow tube.

[0020] The liquid storage chamber A is for storing a liquid matrix capable of generating an aerosol, and is defined by at least a portion of the inner surface of the upper housing 11, the outer surface of the atomizing assembly 13, and the inner surface of the holder 15.

[0021] The liquid matrix preferably comprises a tobacco-containing material, the tobacco-containing material comprising volatile tobacco flavor compounds that are released from the liquid matrix upon heating. Alternatively or additionally, the liquid matrix may comprise a non-tobacco material. The liquid matrix may comprise water, ethanol or other solvents, plant extracts, nicotine solution, and natural or artificial flavorings. Preferably, the liquid matrix further comprises an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.

[0022] The sealing member 12 is provided between the transport tube 11a and the atomizing assembly 13, between the atomizing assembly 13 and the holder 15, and between the holder 15 and the upper housing 11, and seals the gaps between the transport tube 11a and the atomizing assembly 13, between the atomizing assembly 13 and the holder 15, and between the holder 15 and the upper housing 11. The sealing member 12 is made of a flexible material such as silicone rubber. In another example, the sealing member 12 may include multiple non-integral sealing members, for example, one sealing member provided between the transport tube 11a and the atomizing assembly 13 and another sealing member provided between the holder 15 and the upper housing 11. In another example, the sealing member 12 may be integrally molded with the holder 15 (or the upper housing 11), for example, by two-color injection molding. In another example, the sealing member 12 may not be provided.

[0023] In further implementations, an air pressure equalization passage may be provided within the sealing member 12, and / or between the sealing member 12 and the transport pipe 11a, and / or between the sealing member 12 and the upper housing 11, and / or between the transport pipe 11a and the atomization assembly 13, and / or between the holder 15 and the upper housing 11, to replenish the liquid storage chamber A with gas to equalize the air pressure inside and outside the liquid storage chamber A and facilitate the transfer of the liquid matrix.

[0024] As shown in FIG. 5, the atomizing assembly 13 includes a support 131 , a heating element 132 , a heat insulating member 133 , a liquid transfer unit 134 and a holder 135 .

[0025] The support 131 is configured as a tubular structure having openings at both ends, and its cross section may be circular, elliptical, rectangular, racetrack-shaped, annular, or any other shape, etc. The upper end of the support 131 extends to the transport pipe 11a, the lower end of the transport pipe 11a passes through the opening at the upper end of the support 131 and extends into the support 131, the lower end of the support 131 is housed or held in the second connection portion 152 of the holder 15, and the opening at the lower end of the support 131 communicates with the air intake port 152b.

[0026] In a further embodiment, the outer surface of the support 131 near its upper end has a positioning portion 131a extending radially outward, and the inner surface of the first connecting portion 151 of the holder 15 has a recessed groove 151a. The engagement between the positioning portion 131a and the recessed groove 151a makes it easy to mount the support 131 in the holder 15.

[0027] In a further embodiment, a support portion 152a is provided in the second connecting portion 152 of the holder 15, and a lower end of the support 131 abuts against the support portion 152a. This allows the support 131 to be supported by the support portion 152a when the support 131 is attached to the holder 15. In a preferred embodiment, the support portion 152a includes a plurality of projections spaced apart from one another, which extend in the vertical direction and protrude from the inner surface of the second connecting portion 152.

[0028] The sidewall of the support 131 has a liquid supply port 131b, and the support 131 is provided with a storage chamber communicating with the liquid supply port 131b and an airflow passage communicating with the storage chamber. As can be seen from FIG. 4, a portion of the liquid storage chamber A defined by the inner surface of the second connecting portion 152 and the outer surface of the support 131, along with the storage chamber and the airflow passage, is arranged in sequence along the width direction of the housing assembly. This portion of the liquid storage chamber A and the airflow passage are located on both sides of the heating element 132, with a portion of the surface of the liquid transfer unit 134 defining the boundary of this portion of the liquid storage chamber A and a portion of the surface of the heating element 132 defining the boundary of the airflow passage. This increases the volume of the liquid storage chamber A and allows the liquid matrix to be smoothly transferred to the heating element 132 via the liquid supply port 131b. Air flows in through an opening at the bottom of the support 131, passes through the airflow passage, and then flows out of an opening at the top of the support 131 into the transport pipe 11a. That is, the opening at the lower end of the support 131 defines an intake port, and the opening at the upper end of the support 131 defines an exhaust port.

[0029] The heating element 132 is inductively coupled to the magnetic field generator 26 and positioned as a susceptor that is penetrated by the changing magnetic field to generate heat and heat the liquid matrix, generating an aerosol for inhalation. The heating element 132 can be made from at least one of the following materials: aluminum, iron, nickel, copper, bronze, cobalt, common carbon steel, stainless steel, ferritic stainless steel, martensitic stainless steel, or austenitic stainless steel.

[0030] The heating element 132 is mounted in the support 131 via the liquid supply port 131b and accommodated in the accommodation chamber. The heating element 132 and the liquid transfer unit 134 are arranged to extend in the vertical direction of the support 131. The heating element 132 is plate-shaped and has a plurality of holes, although the number and shape of the holes are not limited. One surface of the heating element 132 communicates with the liquid storage chamber A via the liquid supply port 131b, i.e., the liquid matrix stored in the liquid storage chamber A can flow into the heating element 132 through the liquid supply port 131b, and at least a portion of the airflow passage is defined between another surface on the opposite side of the heating element 132 and the inner surface of the support 131. The holes penetrate the two surfaces of the heating element 132.

[0031] The heat insulating member 133 is also attached to the support 131 via the liquid supply port 131b and accommodated in the accommodation chamber. At least a portion of the heat insulating member 133 is disposed between the support 131 and the heating element 132, separating the support 131 from the heating element 132 and preventing the problem of excessive heat transfer from the heating element 132 to the support 131, resulting in heat loss. The heat insulating member 133 can be made of a flexible material, for example, a silicone rubber material with high temperature resistance, which allows the flexible sealing performance of the silicone rubber material to seal the gap between the inner surface of the support 131 and the heating element 132.

[0032] In a preferred embodiment, the insulating member 133 is configured in a racetrack shape surrounding a through-hole (window), and an engagement hole 133a is provided in the insulating member 133, and one end of the heating element 132 has an engagement member 132a that protrudes into the insulating member 133. In this manner, the engagement between the engagement member 132a and the engagement hole 133a holds the heating element 132 on one surface of the insulating member 133, and another surface on the opposite side of the insulating member 133 abuts against a stopper portion 131c in the support 131, which includes a protrusion protruding from the inner surface of the support 131. After the heating element 132 and the insulating member 133 are engaged and connected, the surface of the portion of the heating element 132 adjacent to its edge comes into contact with the insulating member 133, and the hole of the heating element 132 is exposed through the through-hole of the insulating member 133, i.e., exposed to the airflow passage, allowing the atomized aerosol to escape into the airflow passage. This allows the heating element 132 and the heat insulating member 133 to be mounted together in the support 131 via the liquid supply port 131b.

[0033] The liquid transfer unit 134 is for absorbing the liquid matrix in the liquid storage chamber A and transferring the absorbed liquid matrix to the heating element 132. The liquid transfer unit 134 can be made of natural or artificial fiber materials, such as natural cotton fiber, glass fiber, sponge, nonwoven fabric, etc. The liquid transfer unit 134 is also generally plate-shaped, with one surface in contact with the surface of the heating element 132 and another surface on the opposite side communicating with the liquid storage chamber A.

[0034] The holder 135 is provided at the liquid supply port 131b. The holder 135 is also configured in a racetrack shape surrounding the through-hole. The holder 135 is connected to the support 131. The holder 135 includes a main body 135a and a lug 135b provided on the main body 135a. The main body 135a is attached to the support 131 via the liquid supply port 131b, and the lug 135b is exposed to the side wall of the support 131, protrudes in the width direction or length direction of the main body 135a, and abuts against the side wall of the support 131. The holder 135 allows the liquid transfer unit 134 to be held between the liquid supply port 131b and the heating element 132 and brought into contact with one surface of the heating element 132, i.e., abut against the heating element 132.

[0035] When mounting, the heating element 132 and the insulating member 133 may be engaged and connected, then the heating element 132 and the insulating member 133 may both be mounted in the support 131 via the liquid supply port 131b, then the liquid transfer unit 134 may be mounted in the support 131 via the liquid supply port 131b, and finally the holder 135 may be provided on the liquid supply port 131b so that the holder 135 presses the liquid transfer unit 134 to bring the surface of the liquid transfer unit 134 into suitable contact with the surface of the heating element 132.

[0036] The liquid matrix stored in the liquid storage chamber A can pass through the holder 135, be sucked up by the liquid transfer unit 134, and be transferred to the heating element 132 (shown as R1 in FIG. 4). The aerosol generated by atomization of the heating element 132 can escape into the support 131 or the airflow passage through the holes and the through-holes in the insulating member 133, and the aerosol mixes with the outside air and then flows into the transport pipe 11a, where it can be inhaled by the user or smoker through the mouthpiece (shown as R2 in FIG. 4).

[0037] The sealing member 14 is for sealing the gap between the support 131 and the second connecting portion 152 of the holder 15. Similar to the sealing member 12, the sealing member 14 is made of a flexible material such as silicone rubber. Other structural designs can be referred to the sealing member 12.

[0038] 6 and 7, the holder 15 and the upper housing 11 constitute a housing assembly of the atomizer 10. The holder 15 includes an integrally molded first connecting portion 151 and a second connecting portion 152. In another example, the first connecting portion 151 and the second connecting portion 152 may be formed non-integrally.

[0039] The first connecting portion 151 is accommodated in the upper housing 11 and has a generally elliptical cross section. The area of ​​the upper end opening of the first connecting portion 151 is larger than the area of ​​the lower end opening, and the lower end opening is adjacent to the second connecting portion 152 or defines the upper end opening of the second connecting portion 152.

[0040] In a preferred embodiment, a protrusion 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 engagement between the protrusion 151b and the groove realizes the engagement connection between the first connecting portion 151 and the upper housing 11.

[0041] In a preferred embodiment, the first connecting portion 151 has a support portion 151c extending radially outward at its lower end to support the open end of the upper housing 11. The first connecting portion 151 further has a stepped portion 151d on its outer surface near its upper end to hold a portion of the sealing member 12.

[0042] The second connecting portion 152 is exposed to the outside of the upper housing 11 or the atomizer 10. As a result, the upper housing 11 constitutes a first portion of the housing assembly of the atomizer 10, and the second connecting portion 152 constitutes a second portion of the housing assembly of the atomizer 10. The radial dimension of the second portion is smaller than that of the first portion.

[0043] The second connecting portion 152 is configured in a sleeve shape and has 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 width dimension of the cross section of the second connecting portion 152 is smaller than the width dimension of the first connecting portion 151, or the length dimension of the cross section of the second connecting portion 152 is smaller than the length dimension of the first connecting portion 151, or the outer diameter dimension of the cross section of the second connecting portion 152 is smaller than the outer diameter 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 151, but the length dimension of the second connecting portion 152 extending in the vertical direction is larger than the length dimension of the first connecting portion 151.

[0044] In a preferred embodiment, the second connecting portion 152 has an elliptical cross section, and the radial dimension is the dimension of the major or minor axis of the ellipse. The difference between the major and minor axes of the second connecting portion 152 is 0.5 mm to 2 mm (preferably 0.5 mm to 1.5 mm, and 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, even more preferably 8.2 mm to 8.6 mm, and even more preferably 8.4 mm to 8.6 mm). The length of the minor axis d2 of the ellipse is 6 mm to 8 mm (preferably 7 mm to 8 mm, more preferably 7.2 mm to 8 mm, even more preferably 7.4 mm to 8 mm, even more preferably 7.6 mm to 8 mm, and even more preferably 7.6 mm to 7.8 mm). In a specific embodiment, the length of the major axis d1 is 8.5 mm, and the length of the minor axis d2 is 7.7 mm.

[0045] In another example, the cross section of the second connecting portion 152 may be circular. The radial dimension of the second connecting portion 152 is the diameter of the circle.

[0046] An air inlet 152b is provided at the bottom of the second connection portion 152, and a wall in which the air inlet 152b is formed protrudes from the bottom of the second connection portion 152 so as to prevent the liquid matrix collected in the collection chamber 152c from flowing directly through the air inlet 152b to the power supply assembly 20. External air flows in through the air inlet 152b, flows through the sealing member 14, the support 131, and the transport pipe 11a in this order, and then flows out from the exhaust port of the upper housing 11.

[0047] 8 and 9 show another atomizing assembly provided in the present application. This differs from the example shown in FIGS. 2 to 7 in that the insulating member 133 is configured as a storage chamber structure with openings at both ends, with the opening at one end of the insulating member 133 communicating with the liquid supply port 131b and the opening at the other end of the insulating member 133 communicating with the airflow passage. The hollow portion 133b inside the insulating member 133 is for accommodating the heating element 132, the liquid transfer unit 134, and the main body 135a of the holder 135, which can be attached to the hollow portion 133b inside the insulating member 133 via one end adjacent to the liquid supply port 131b of the insulating member 133. The main body 135a of the holder 135 can hold the heating element 132 and the liquid transfer unit 134 within the insulating member 133, and the lug 135b of the holder 135 is exposed to the outside of the insulating member 133. One end of the heat insulating member 133 close to the airflow passage further has a stopper portion 133c that abuts against one surface of the heat generating element 132 and restricts movement of the heat generating element 132 into the airflow passage.

[0048] During installation, the heating element 132, the liquid transfer unit 134, and the holder 135 may first be attached to the insulating member 133 to form an integrated module, and then the module may be attached to the support 131 via the liquid supply port 131b. After installation, the lug 135b of the holder 135 remains exposed to the side wall of the support 131 and abuts against the side wall. Compared to the example shown in Figures 2 to 7, the alternative atomization assembly in the example shown in Figures 8 and 9 is easier to install. The aerosol generated by atomization of the heating element 132 passes through an opening at one end of the insulating member 133 that is close to the airflow passage and escapes into the airflow passage.

[0049] 10 to 12 show yet another atomizing assembly provided in the present application. This atomizing assembly differs from the example shown in FIGS. 2 to 7 in that the atomizing assembly 13 does not include a holder 135, and the heating element 132, heat insulating member 133, and liquid transfer unit 134 are mounted within the support 131 via an opening at the bottom of the support 131. Specifically, this is similar to the example shown in FIGS. 8 and 9 in that the heat insulating member 133 is configured as a storage chamber structure with openings at both ends. However, this differs from the example shown in FIGS. 8 and 9 in that the heat insulating member 133 has a mounting opening (not shown) in its sidewall and, as shown in FIG. 12, two opposing engagement grooves 133d on its inner surface. The heating element 132 can be mounted to the heat insulating member 133 via the mounting opening in its sidewall along the engagement grooves 133d, and the engagement grooves 133d can engage or hold opposite ends of the heating element 132 in the width direction. Similarly, the stopper portion 131c in the support 131 is configured as a groove structure, and after installation, the heating element 132 and the heat insulating member 133 can be installed in the support 131 along the stopper portion 131c via the opening at the bottom end of the support 131. The stopper portion 131c can hold opposite ends of the heat insulating member 133 in the width direction. One surface of the liquid transfer unit 134 contacts the heating element 132, and another opposite surface communicates with the liquid storage chamber A via the liquid supply port 131b. The liquid transfer unit 134 is also installed in the support 131 via the opening at the bottom end of the support 131. It can be understood that the liquid transfer unit 134 can be installed in the support 131 together with the heating element 132 and the heat insulating member 133. For example, the opposite ends of the liquid transfer unit 134 in the width direction are sandwiched between the heat insulating members 133, and then the liquid transfer unit 134 is installed in the support 131 together with the heating element 132 and the heat insulating member 133.

[0050] FIG. 13 shows yet another atomization assembly provided in the present application. This atomization assembly differs from the examples shown in FIGS. 2 to 7 in that the insulating member 133 and the heating element 132 are integrally molded, which can be achieved by welding, crimping, or other means, and the insulating member 133 is disposed around and surrounds the heating element 132. The insulating member 133 is made of a non-ferromagnetic material, which does not generate heat when penetrated by a changing magnetic field, or the amount of heat generated by the insulating member 133 is much lower than that of the heating element 132. For example, the amount of heat generated by the insulating member 133 is several orders of magnitude lower than that of the heating element 132. Non-ferromagnetic materials include, but are not limited to, austenitic stainless steel, aluminum, copper, gold, silver, lithium, magnesium, etc.

[0051] When mounting, the heating element 132 is brought into contact with the stopper portion 131c of the support 131 via the insulating member 133, then the liquid transfer unit 134 is mounted in the support 131 via the liquid supply port 131b, and finally, the holder 135 is provided on the liquid supply port 131b so that the holder 135 presses the liquid transfer unit 134 and brings one side of the liquid transfer unit 134 into suitable contact with the heating element 132.

[0052] It should be noted that the heating element 132 is not limited to an electromagnetic induction heating element, but may be a heating element such as a general resistance heating element, an ultrasonic atomization element, or an infrared heating element.

[0053] As shown in FIGS. 14 to 19, the power supply assembly 20 includes a lower housing 21, a lower support 22, a battery cell 23, a circuit 24, a base 25, a magnetic field generator 26, a shield 27, and a sensor 28.

[0054] The lower housing 21 is a columnar structure with openings at both ends. The lower housing 21 and the upper housing 11 define the outer housing of the electronic atomization device 100.

[0055] The outer surface of the lower housing 21 is provided with an air inlet 21a for allowing external air to flow into the lower housing 21. Parts of the outer surface of both the front and rear sides of the lower housing 21 protrude to form protrusions 21b (or parts of the inner surface of both the front and rear sides of the lower housing 21 are recessed to form protrusions 21b on the outer surface of the lower housing 21), and the protrusions 21b increase the thickness dimension of part of the electronic atomization device 100, making it possible to accommodate a large magnetic field generator 26 such as an induction coil.

[0056] The lower support 22 includes a receiving portion 221 and a mounting portion 222 separated by a separator 223 .

[0057] The lower support 22 is housed within the lower housing 21. The longitudinal dimension of the lower support 22 is smaller than the longitudinal dimension of the lower housing 21. A receiving portion B is defined and formed between the upper end of the lower support 22 and the upper end of the lower housing 21, or between the lower support 22 and the inner surface of the lower housing 21, and the lower end of the lower support 22 abuts against the edge of the lower end of the lower housing 21, and after installation, a part of the upper housing 11 is received within the receiving portion B.

[0058] The outer surface of the accommodating portion 221 has a cantilever 221a that is engaged with and connected to a recessed groove on the inner surface of the lower housing 21. The inner surface of the accommodating portion 221 has a step portion 221b, and the main portion 25a of the base 25 is accommodated in the accommodating portion 221, the extension portion 25b of the base 25 abuts against the step portion 221b, and the multiple extension portions 25c of the base 25 abut against the separator 223.

[0059] Components can be attached to the front and back of the mounting part 222. In this example, the battery cell 23 is attached to the front of the mounting part 222, and the circuit 24 is attached to the back of the mounting part 222, that is, they are arranged in that order in the thickness direction of the electronic atomization device 100. The mounting part 222 is provided with a receiving cavity 222a for receiving the sensor 28 and a receiving cavity 222b for receiving a motor (not shown) for generating a notification signal to notify the user, and the specific notification information is not limited thereto.

[0060] The separator 223 has a groove 223a, which is coaxial with the receiving portion C. An air inlet 223b is provided in the groove 223a, and air can pass through the air inlet 223b and flow into the groove 223a, and then pass through the air intake 152b of the holder 15 and into the atomizer 10. A detection passage 223c communicating with the receiving cavity 222a is provided in the groove 223a.

[0061] The battery cell 23 provides power for operating the electronic atomization device 100. The battery cell 23 may be a rechargeable battery cell or a disposable battery cell.

[0062] The circuitry 24 can control the overall operation of the electronic atomization device 100. The circuitry 24 controls the operation of the battery cell 23 and the magnetic field generator 26, as well as the operation of other elements in the electronic atomization device 100. The circuitry 24 includes at least one processor. The processor may include a logic gate array or a combination of a general-purpose microprocessor and memory that stores a program executable by the microprocessor. However, those skilled in the art will appreciate that the circuitry 24 may include other types of hardware.

[0063] The base 25 includes a main body portion 25a, the hollow portion of which defines or forms at least a portion of the receiving portion C, having an extension portion 25b at its upper end and a plurality of extension portions 25c at its lower end. After attachment, at least a portion of the second connecting portion 152 of the holder 15 is received within the receiving portion C. The radial dimension of the receiving portion C is 7 mm to 20 mm.

[0064] In a preferred embodiment, the cross section of the main body portion 25a is elliptical, i.e., the receiving portion C is elliptical, and the radial dimension of the receiving portion C is the dimension of the major axis or minor axis of the ellipse. The difference between the major axis and minor axis of the receiving portion C is 0.5 mm to 2 mm (preferably 0.5 mm to 1.5 mm, and more preferably 0.5 mm to 1 mm). The receiving portion C being elliptical contributes to making the electronic atomization device 100 flatter overall, making the electronic atomization device 100 more aesthetically pleasing. Specifically, the length of the major axis d11 of the ellipse is 7 mm to 10 mm (preferably 7 mm to 9 mm, more preferably 7.5 mm to 9 mm, even more preferably 8 mm to 9 mm, and even more preferably 8.5 mm to 9 mm). The length of the minor axis d12 of the ellipse is 7 mm to 9 mm (preferably 7 mm to 8.5 mm, more preferably 7 mm to 8.3 mm, even more preferably 7 mm to 8.1 mm, even more preferably 7.5 mm to 8.1 mm, even more preferably 7.7 mm to 8.1 mm, and even more preferably 7.9 mm to 8.1 mm). In a specific example, the length of the major axis d11 is 8.8 mm, and the length of the minor axis d12 is 8 mm.

[0065] The magnetic field generator 26 generates a magnetic field that changes with an alternating current and includes, but is not limited to, an induction coil. The magnetic field generator 26 is disposed adjacent to the receiving portion C. At least a portion of the magnetic field generator 26 surrounds the receiving portion C. The main portion 26a of the magnetic field generator 26 is fitted onto the main portion 25a of the base 25. The electrical connection portions 26b and 26c of the magnetic field generator 26 are electrically connected to the battery cell 23. When at least a portion of the second connection portion 152 of the holder 15 is received in the receiving portion C, the heating element 132 is completely positioned within the receiving portion C, allowing the magnetic field generated by the magnetic field generator 26 to substantially cover the heating element 132. This reduces the coupling distance between the heating element 132 and the magnetic field generator 26, improving the heating efficiency of the atomizer 10. In a preferred embodiment, when at least a portion of the second connecting portion 152 of the holder 15 is received in the receiving portion C, the heating element 132 and the magnetic field generator 26 are coaxial and extend in the axial direction of the electronic atomization device 100, thereby contributing to improving the heating efficiency of the atomizer 10. The axial extension length of the magnetic field generator 26 is greater than the axial extension length of the heating element 132.

[0066] The main body portion 26a of the magnetic field generator 26 is a solenoid coil made by winding a long conductor material. For example, it may be formed by winding 1600 to 1900 strands of 0.02 mm conductor wire, or 750 to 1050 strands of 0.03 mm conductor wire. The number of turns or windings of the solenoid coil is 6 to 20 turns, preferably 6 to 15 turns, more preferably 6 to 12 turns, and even more preferably 6 to 10 turns. The spacing between adjacent windings is approximately 0.1 to 0.5 mm, and in a specific embodiment, the spacing between adjacent windings is 0.2 or 0.4 mm. The spacing between adjacent windings may be the same or different.

[0067] The cross section of the conductor material may be rectangular, circular, etc.

[0068] In a preferred embodiment, the cross section of the conductor material has a first side extending in the radial direction X of the magnetic field generator 26 and a second side extending in the axial direction Y of the magnetic field generator 26. The cross section of the conductor material is approximately rectangular, and the dimension L of the first side is greater than the dimension H of the second side, so that the conductor material of the magnetic field generator 26 has a flat structure, which helps to increase the number of turns per unit length of the magnetic field generator 26 and further improve the inductance value. In addition, the second side is disposed in close contact with the wall of the receiving portion C, i.e., in close contact with the outer surface of the main body portion 25a of the base 25, which makes it possible to increase the number of turns of the magnetic field generator 26 within a limited height space.

[0069] In a preferred embodiment, the ratio of the dimension L of the first side to the dimension H of the second side is 1.5 to 3, preferably 2 to 3, and more preferably 2.5 to 3. For example, in one specific embodiment, the ratio of the dimension L of the first side to the dimension H of the second side is 2.8.

[0070] In a preferred embodiment, the first side dimension L is about 1 to 5 mm, and the second side dimension H is about 0.3 to 1 mm. For example, in one specific embodiment, the first side dimension L is 2.5 mm, and the second side dimension H is 0.9 mm.

[0071] In a preferred implementation, the main body portion 26a of the magnetic field generator 26 has a total length along the axial direction Y of approximately 5 to 20 mm, and in one specific embodiment, the main body portion 26a of the magnetic field generator 26 has a total length along the axial direction Y of 12.2 mm.

[0072] The cross section of the hollow portion of the main body 26a of the magnetic field generator 26 may be circular or elliptical.

[0073] In a preferred embodiment, the cross section of the hollow portion of the main body portion 26a of the magnetic field generator 26 is non-circular, for example, elliptical, oval, or racetrack-shaped. In some examples, the difference between the major and minor axes of the ellipse is 0.5 mm to 2 mm. Specifically, the length of the major axis R1 of the ellipse is 8 mm to 15 mm (preferably 8 mm to 12 mm, more preferably 8 mm to 10 mm, and even more preferably 9 mm to 10 mm). The length of the minor axis R2 of the ellipse is 8 mm to 13 mm (preferably 8 mm to 11 mm, more preferably 8 mm to 10 mm, and even more preferably 8 mm to 9 mm). In one specific example, the length of the major axis R1 of the ellipse is 9.7 mm, and the length of the minor axis R2 of the ellipse is 8.9 mm.

[0074] The shield 27 is provided to surround or fitted onto the main body portion 26a of the magnetic field generator 26. The shield 27 shields the magnetic field dispersed in the approximately radial direction by the magnetic field generator 26, thereby preventing the dispersed magnetic field from affecting other components.

[0075] The sensor 28 detects the change in the airflow in the groove 223a through the detection passage 223c, that is, detects that the user is inhaling, and generates a signal to control the atomizer 10 to operate.
