[0069] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0070] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100. Figure 1 In the illustrated embodiment, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are separable or detachable relative to each other; an electronic atomizing device having such a separable or detachable atomizer 100 and power supply mechanism 200 is, for example, a so-called "refillable" electronic atomizing device. Alternatively, in some further variations, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are securely enclosed and fixed by the housing components of the electronic atomizing device, thereby preventing the atomizer 100 and power supply mechanism 200 from being detachable relative to each other; an electronic atomizing device having such a non-detachable atomizer 100 and power supply mechanism 200 relative to each other is, for example, a so-called "integrated or disposable" electronic atomizing device.

[0071] In an alternative embodiment, for example Figure 1 As shown, the power supply mechanism 200 includes a receiving cavity 270 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 230 at least partially exposed on the surface of the receiving cavity 270 for supplying power to the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated within the power supply mechanism 200.

[0072] according to Figure 1 In the exemplary embodiment shown, an electrical contact 21 is provided at one end of the atomizer 100 along the length direction, so that when at least a portion of the atomizer 100 is received in the receiving cavity 270, the electrical contact 21 forms an electrical conductivity by contacting and abutting against the electrical contact 230.

[0073] exist Figure 1 In the exemplary embodiment shown, a sealing member 260 is provided inside the power supply mechanism 200, and the sealing member 260 divides at least a portion of the internal space of the power supply mechanism 200 to form the receiving cavity 270. Figure 1 In the exemplary embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power supply mechanism 200, and is preferably made of a flexible material, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 270 from flowing into components such as the controller 220 and sensor 250 inside the power supply mechanism 200.

[0074] exist Figure 1 In the exemplary embodiment shown, the power supply mechanism 200 further includes a battery cell 210 for power supply located at the other end of the receiving cavity 270 along the length direction; and a controller 220 disposed between the battery cell 210 and the receiving cavity 270, the controller 220 being operable to guide current between the battery cell 210 and the electrical contact 230.

[0075] In use, the power supply mechanism 200 includes a sensor 250 for sensing the suction airflow generated when the atomizer 100 is inhaled, and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250.

[0076] exist Figure 1 In the exemplary embodiment shown, the power supply mechanism 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210.

[0078] The proximal end 110 and the distal end 120 are opposite each other along the length direction; wherein, according to the needs of normal use, the proximal end 110 is configured as the end for the user to inhale the aerosol, and the proximal end 110 is provided with an air outlet 111 for the user to inhale; while the distal end 120 is the end that is combined with the power supply mechanism 200.

[0079] according to Figures 2 to 5 As shown, the atomizer 100 includes:

[0080] The housing 10 may be defined by one or more components, defining at least a portion of the outer surface of the atomizer 100; the housing 10 is generally flat and hollow, containing necessary functional devices for storing and atomizing the liquid matrix.

[0081] In this embodiment, the housing 10 defines the proximal end 110 of the atomizer 100 and the air outlet 111 located at the proximal end 110, and has an opening facing the distal end 120; the opening is used to install various functional components inside the housing 10.

After assembly, the end cap 20 defines the distal end 120 of the atomizer 100; and the housing 10 and the end cap 20 together define the outer shell or outer surface of the atomizer 100.

Figures 2 to 5 As shown, the atomizing mechanism 40 is arranged longitudinally along the atomizer 100, and the space between the atomizing mechanism 40 and the outer casing 10 forms a liquid storage chamber 113 for storing the liquid matrix. The first end of the atomizing mechanism 40 relative to the proximal end 110 communicates with the air outlet 111, thereby transporting the generated aerosol to the air outlet 111 for inhalation. Specifically, a tubular connecting wall 112 extending from the air outlet 111 toward the distal end 120 is also arranged inside the outer casing 10. During assembly, the tubular connecting wall 112 is inserted into and connected to the atomizing mechanism 40, and provides aerosol transfer between the atomizing mechanism 40 and the air outlet 111. In this embodiment, the tubular connecting wall 112 and the outer casing 10 are integrally molded.

[0084] In one embodiment, at least a portion of the outer casing 10 surrounding the liquid reservoir 113 is transparent; thus, it is advantageous to view the remaining amount of liquid matrix within the liquid reservoir 113 through the outer casing 10 during use. In some embodiments, the volume of the liquid matrix that can be stored in the liquid reservoir 113 may be between 2 and 15 mL.

[0085] See Figures 2 to 5 As shown, the atomizer 100 also includes:

[0086] A flexible base 50 is located within the housing 10 and positioned near the end cap 20; during assembly, the base 50 is at least partially supported or held by the end cap 20. The flexible base 50 is made of a flexible material, such as silicone or a thermoplastic elastomer. After assembly, the flexible base 50 defines and seals the liquid reservoir 113 on the side near the distal end 120. Furthermore, the base 50 is arranged substantially perpendicular to the longitudinal direction of the atomizer 100, and the base 50 is substantially adapted to the inner surface of the housing 10. See also... Figures 2 to 5 As shown, a plurality of longitudinally extending protrusions 114 are arranged on the inner surface of the housing 10; after assembly, the base 50 longitudinally abuts against the protrusions 114 to provide a stop.

[0087] according to Figures 3 to 5 As shown, the base 50 may have a first side facing or near the liquid storage chamber 113, and a second side facing away from the first side or towards the end cap 20; the base 50 is provided with:

[0088] A connector 55 is arranged on the first side; during assembly, at least a portion of the atomizing mechanism 40 is inserted into the connector 55 and then assembled with the base 50. When the atomizing mechanism 40 is inserted into the connector 55, the first liquid guide hole 411 of the atomizing mechanism 40 is exposed outside the connector 55.

[0089] according to Figures 3 to 5 As shown, the atomizing mechanism 40 is held longitudinally between the connecting wall 112 and the base 50, and is supported or fixed by them.

[0090] according to Figures 3 to 5 As shown, the base 50 is also equipped with:

[0091] The air hole 52 extends from the surface of the second side of the base 50 into the insertion groove 55, so that during suction, the external air entering from the air inlet 22 can enter the atomizing mechanism 40 through the air hole 52.

[0092] When the user inhales through the outlet 111, the airflow path within the atomizer 100 is as follows: Figures 3 to 5 As indicated by the middle arrow R2, external air enters through the air inlet 22 and enters the atomizing mechanism 40 through the air hole 52, thereby carrying the generated aerosol and outputting it to the air outlet 111 through the connecting wall 112.

[0093] according to Figures 3 to 5 As shown, the base 50 is also equipped with:

[0094] The contact hole 51 extends through or into the base 50 from the surface of the second side of the base 50. After assembly, the electrical contact 21 is at least partially inserted into the contact hole 51 and forms a connection with the conductive lead 481 of the atomizing mechanism 40 by contacting, abutting, or welding, thereby supplying power to the heating element 48 of the atomizing mechanism 40.

[0096] A wire-fixing groove 54 is formed or defined on the surface of the second side of the base 50; the wire-fixing groove 54 is connected to the contact hole 51. After assembly, the conductive lead 481 passes through the insertion groove 55 to the second side of the base 50 and then bends from the wire-fixing groove 54 into the contact hole 51. The wire-fixing groove 54 is used to at least partially restrict and retain the conductive lead 481.

[0097] according to Figures 3 to 5 As shown, the end cap 20 is also provided with a rod-shaped ventilation section 23 extending toward the proximal end 110; a longitudinally extending ventilation groove 231 is provided on the outer surface of the ventilation section 23.

[0098] according to Figures 3 to 5 As shown, the ventilation section 23 of the end cap 20 extends from the second side of the base 50 through the ventilation hole 53 into the liquid storage chamber 113. A ventilation channel is defined between the outer and inner surfaces of the ventilation section 23 by the ventilation groove 231, which is used to replenish air into the liquid storage chamber 113 to alleviate negative pressure. Therefore, when the negative pressure in the liquid storage chamber 113 exceeds a threshold due to the consumption of the liquid matrix, external air can enter the liquid storage chamber 113 through the ventilation channel defined by the ventilation groove 231 to alleviate the negative pressure.

[0099] In this embodiment, the vent 53 is also configured as an injection port for injecting a liquid matrix into the liquid reservoir 113; during the injection operation, the atomizer 100 is inverted and the end cap 20 is removed to expose the vent 53 for use as an injection port.

The distance between the second tubular element 45 and the first tubular element 41 may be between 1 and 5 mm. In some optional embodiments, the distance between the second tubular element 45 and the first tubular element 41 may be between 1.5 and 4.5 mm. For example, in a more specific embodiment, the distance between the second tubular element 45 and the first tubular element 41 is 2.5 mm.

[0117] according to Figures 3 to 7 As shown, the atomizing mechanism 40 also includes:

[0118] The atomizing component is housed and held within the second tubular element 45 for receiving the liquid matrix and heating it to generate an aerosol.

[0119] In this embodiment, the atomizing component includes:

[0120] Porous element 47 and heating element 48 incorporated in porous element 47.

[0121] In some embodiments, the porous element 47 is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge; the porous element 47 is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the atomizing mechanism 40 / atomizer 100. Alternatively, in some other variations, the porous element 47 may also include rigid porous elements, such as porous ceramics or porous glass. The outer surface of the porous element 47 is used to absorb the liquid matrix, such as… Figure 5 As indicated by the middle arrow R1.

[0122] In some embodiments, the inner surface of the porous element 47 in the radial direction is configured as an atomizing surface, which is combined with / adhered to / abuts against the heating element 48; subsequently, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 48 to generate an aerosol and released. See also Figures 3 to 7 As shown, the heating element 48 is arranged to extend longitudinally along the porous element 47, and the heating element 48 is coaxially arranged with the porous element 47. In some alternative embodiments, the heating element 48 may be a resistance heating mesh, a resistance heating coil, etc. In this embodiment, the heating element 48 is a heating element wound from a sheet-like or mesh-like substrate. Conductive leads 481 are welded or arranged on the heating element 48, and current is guided on the heating element 48 through the conductive leads 481.

[0123] In some variations, the heating element 48 may be bonded to the porous element 47 by means of printing, deposition, sintering, or physical assembly. In some other variations, the porous element 47 may have a planar or curved surface for supporting the heating element 48, which is formed on the planar or curved surface of the porous element 47 by means of mounting, printing, deposition, etc. Alternatively, in some variations, the heating element 48 may be a conductive trace formed on the surface of the porous element 47. In some variations, the conductive trace of the heating element 48 may be in the form of printed lines formed by printing. In some variations, the heating element 48 may be a patterned conductive trace. In some variations, the heating element 48 may be planar. In some variations, the heating element 48 may be a tortuous, meandering, reciprocating, or zigzag-extending conductive trace.

[0124] See Figures 3 to 7 As shown, after assembly, at least a portion of the conductive lead 481 of the heating element 48 extends through to the second end of the first tubular element 41, and then bends and extends into the contact hole 51 of the base 50 to contact the electrical contact 21 for conduction.

[0125] In this embodiment, the atomizing component and / or porous element 47 is arranged closer to the second end of the atomizing mechanism 40. The distance between the atomizing component and / or porous element 47 and the second end is less than the distance between it and the first end.

[0126] In one embodiment, a plurality of second liquid guiding holes 451 are arranged on the wall of the second tubular element 45; the porous element 47 receives the liquid matrix at least through the second liquid guiding holes 451. After assembly, the second liquid guiding holes 451 are opposite to a portion of the outer surface of the porous element 47.

[0127] In this embodiment, a positioning notch 452 is also provided on the wall of the second tubular element 45; the positioning notch 452 extends longitudinally to the second end of the second tubular element 45. The porous element 47 has a positioning protrusion 472; during assembly, after aligning the positioning protrusion 472 with the positioning notch 452, the porous element 47 is inserted into or assembled into the second tubular element 45 from its second end. In this embodiment, the porous element 47 can simultaneously receive a liquid matrix through both the second liquid guide hole 451 and the positioning notch 452. After assembly, the positioning protrusion 472 of the porous element 47 may extend into or be exposed above the positioning notch 452.

[0128] according to Figures 3 to 7 As shown, the atomizing mechanism 40 also includes:

[0129] The first capillary element 441 and the second capillary element 442 are arranged longitudinally at intervals between the second tubular element 45 and the first tubular element 41. The second capillary element 442 is closer to the proximal end 110 than the first capillary element 441.

[0130] In some embodiments, the first capillary element 441 and the second capillary element 442 are flexible, for example, made of flexible capillary fiber materials such as cotton fiber, non-woven fiber, sponge, silk fiber, etc.; or in other embodiments, the first capillary element 441 and the second capillary element 442 are rigid, for example, made of rigid porous ceramic body, porous glass, etc.

[0131] according to Figure 3 and Figure 7 As shown, the second capillary element 442 longitudinally abuts against the first sealing plug 42, and is thus at least partially blocked by the first sealing plug 42. The first capillary element 441 longitudinally abuts against the second sealing plug 43, and is thus at least partially blocked by the second sealing plug 43.

[0132] according to Figure 3 and Figure 7 As shown, the second capillary element 442 and / or the first capillary element 441 may be arranged around a portion of the second tubular element 45. According to... Figure 3 and Figure 7 As shown, a buffer space 443 is formed or defined between the first capillary element 441 and the second capillary element 442. In an embodiment, the distance between the first capillary element 441 and the second capillary element 442 may be between 3 and 10 mm; in some preferred embodiments, the distance between the first capillary element 441 and the second capillary element 442 may be between 4 and 8 mm, and more specifically, for example, 6 mm.

[0133] In some embodiments, the spacing between the first capillary element 441 and the second capillary element 442 is less than the extension length of the first capillary element 441 and / or the second capillary element 442. In some embodiments, the extension length of the first capillary element 441 and / or the second capillary element 442 may be between 8 and 12 mm.

[0134] Or in the embodiments, for example Figure 7As shown, the second tubular element 45 may include a first segment 4510, a second segment 4520, and a third segment 4530 arranged longitudinally; the first segment 4510 faces or is close to the distal end 120, and the third segment 4530 faces or is close to the proximal end 110; a first capillary element 441 is arranged around the first segment 4510 of the second tubular element 45, and a second capillary element 442 is arranged around the third segment 4530 of the second tubular element 45. The atomizing assembly / porous element 47 is housed and held within the first segment 4510 of the second tubular element 45; and a second liquid guide hole 451 and a positioning notch 452 are arranged in the first segment 4510 of the second tubular element 45.

[0135] In an embodiment, the second capillary element 442 may be located between the third segment 4530 of the second tubular element 45 and the first tubular element 41; the buffer space 443 may be defined between the second segment 4520 of the second tubular element 45 and the first tubular element 41; and the first capillary element 441 may be located between the first segment 4510 of the second tubular element 45 and the first tubular element 41.

[0136] In this embodiment, the first capillary element 441 is used to absorb and retain the liquid matrix entering from the first liquid guide hole 411 of the first tubular element 41; the porous element 47 then receives the liquid matrix originating from the liquid reservoir 113 from the first capillary element 441 through the second liquid guide hole 451, for example... Figure 5 As indicated by the middle arrow R1.

[0137] In one embodiment, the first liquid guide hole 411 of the first tubular element 41 is offset from the longitudinal center of the first capillary element 441 and / or the porous element 47. For example, in Figure 6 As shown, the first liquid guide hole 411 of the first tubular element 41 is relatively closer to the second end than the longitudinal center of the first capillary element 441 and / or the porous element 47.

[0138] according to Figure 5 As indicated by the middle arrow R2, the atomizer 100 includes:

[0139] An airflow channel defines a path from the air inlet 22 through the atomizing assembly to the air outlet 111, thereby outputting the aerosol to the air outlet 111. In an embodiment, the airflow channel extends through the atomizing mechanism 40. Or more specifically, a longitudinally extending air passage is defined within the atomizing mechanism 40 to carry the generated aerosol out. A portion of the airflow channel through the atomizer 100 is defined by the air passage of the atomizing mechanism 40.

[0140] In an embodiment, the air passage of the atomizing mechanism 40 extends from the first end to the second end; and the air passage of the atomizing mechanism 40 extends through the porous element 47 and / or the second tubular element 45.

[0141] In this embodiment, the air passage within the atomizing mechanism 40 is arranged to form or define the inlet 431 of the second sealing plug 43 and the insertion interface 421 of the first sealing plug 42. Alternatively, the insertion interface 421 of the first sealing plug 42 provides an outlet for the aerosol to be output from the atomizing mechanism 40. After assembly, the air passage within the atomizing mechanism 40 is in communication with the outside atmosphere via the air inlet 22 and / or the air outlet 111.

[0142] according to Figure 3 and Figure 7 As shown, a connecting hole 454 is also arranged on the second section 4520 of the second tubular element 45, connecting the buffer space 443 with the air passage in the atomizing mechanism 40. In an embodiment, the diameter of the connecting hole 454 is greater than 0.1 mm; or, the area of ​​the connecting hole 454 is greater than 0.01 mm². 2 In embodiments, for non-circular connecting holes 454, "diameter" can be characterized as an equivalent diameter or a nominal diameter. In preferred embodiments, the diameter of the connecting hole 454 may be between 0.1 and 3.0 mm; for example, in an embodiment, the diameter of the connecting hole 454 may be between 0.5 and 1.5 mm.

[0143] In some embodiments, the connecting hole 454 is a circular hole; or in some other embodiments, the connecting hole 454 is an elliptical hole, a triangular hole, a square hole, a polygonal hole, or more irregularly shaped holes.

[0144] In use, when the product packaging of the atomizer 100 is placed in a low-pressure environment for an extended period, such as an air transport environment or a high-altitude area, the connecting hole 454 can be used to prevent or reduce leakage of the liquid matrix caused by the pressure inside the reservoir 113 exceeding the external pressure. Specifically, as follows... Figure 6 As shown, when the atomizer 100 is placed in a low-pressure environment for an extended period, such as an air transport environment or a high-altitude area, the pressure of the external atmosphere is lower than the pressure inside the liquid reservoir 113. This pressure difference continuously drives the liquid matrix inside the liquid reservoir 113 to move along... Figure 6 As indicated by the middle arrow R1, a large amount of leakage is transmitted to the porous element 47; furthermore, when the buffer space 443 is connected to the air channel in the atomizing mechanism 40 through the connecting hole 454, the pressure of the outside atmosphere in the low-pressure environment can be transmitted to the buffer space 443, thereby maintaining the same pressure. Figure 6As indicated by arrow R3, the liquid matrix delivered to the porous element 47 via the first capillary element 441 can be at least partially driven to flow towards the buffer space 443 as indicated by arrow R4. Furthermore, in use, on the one hand, the buffer space 443 is connected to the outside atmosphere in a low-pressure environment by the connecting hole 454, which can at least partially divert and buffer the liquid matrix delivered or seeping from the first capillary element 441 to the porous element 47 to reduce leakage; on the other hand, as... Figure 6 As indicated by the middle arrow R4, the liquid matrix in the buffer space 443 of the product packaging where the atomizer 100 is placed flat can flow to the second capillary element 442 and be adsorbed and retained. When the user opens the product packaging and receives the atomizer 100 vertically in the power supply mechanism 200 for use, the liquid matrix adsorbed in the second capillary element 442 will flow back to the first capillary element 441 under the action of gravity and then be delivered to the porous element 47 for atomization.

[0145] In the production of the atomizer 100, the operation of injecting the liquid matrix into the liquid reservoir 113 through the vent 53 of the base 50 after inverting the atomizer 100 may include at least two steps to reduce the volume of residual air bubbles in the liquid reservoir 113 during production. Specifically, the liquid injection operation may include:

[0146] S10, First injection operation: After inverting the nebulizer 100, inject a liquid matrix with a volume equivalent to that of the liquid storage chamber 113, for example, 15 mL, into the liquid storage chamber 113 through the vent 53 of the base 50.

[0147] S20, adjust the atomizer 100 from the inverted state to Figure 5 The liquid matrix in the reservoir 113 is placed in the upright position and held for about 20 seconds, so that a portion of the liquid matrix in the reservoir 113 is passed through the first liquid guide hole 411 to the first capillary element 441, thereby substantially fully absorbing and wetting the liquid matrix in the first capillary element 441.

[0148] S30, Second liquid injection operation: The atomizer 100 is then adjusted to an inverted state, and liquid matrix is ​​injected into the storage chamber 113 again through the air vent 53 of the base 50. The amount of liquid matrix injected this time is mainly to compensate for the reduction in the volume of bubbles formed by the liquid matrix in the storage chamber 113 caused by the first capillary element 441 wetting the liquid matrix in step S20. For example, the amount of liquid matrix injected in this liquid injection operation is equivalent to the amount of liquid matrix that the first capillary element 441 can adsorb, for example, 0.2 to 1 mL.

[0149] Therefore, after the second injection operation, the residual volume of air bubbles in the reservoir 113 can be limited to within 0.2 mL; thus, in environmental testing or negative / high pressure environments, the pressure change in the reservoir 113 can be controlled within a predetermined range, which is beneficial for reducing leakage of the liquid matrix in environmental testing or negative / high pressure environments.

[0150] In this embodiment, the opening of the positioning notch 452 faces the distal end 120. This arrangement, compared to having the opening of the positioning notch 452 facing the proximal end 110, prevents leakage of liquid from a portion of the inner surface of the second capillary element 442 exposed to the airflow channel through the positioning notch 452 in environments with changing pressure. Specifically, when the opening of the positioning notch 452 faces the proximal end 110, the porous element 47 of the atomizing assembly is assembled from the first end into the second tubular element 45; and after assembly, a portion of the inner surface of the second capillary element 442 is exposed to the airflow channel through the positioning notch 452, thus communicating with the outside atmosphere; when the atomizer 100 is laid flat or inverted, the liquid matrix adsorbed and buffered within the second capillary element 442 will leak through the exposed inner surface of the airflow channel. However, using a method such as... Figures 3 to 7 When the opening of the positioning notch 452 faces the distal end 120, the inner surface of the second capillary element 442 is completely isolated from the airflow channel, thus preventing liquid leakage from a pressure-changing environment caused by direct communication with the outside atmosphere. When the opening of the positioning notch 452 faces the distal end 120, the portion of the first capillary element 441 exposed on the inner surface of the positioning notch 452 is shielded and contacted by the positioning protrusion 472 of the porous element 47, forming a buffer that is beneficial for reducing leakage.

[0151] according to Figures 3 to 7 As shown, the atomizing mechanism 40 also includes:

[0152] The isolating element 46 is configured as a sheet. The isolating element 46 is annular in shape surrounding the second tubular element 45. The isolating element 46 is located within the buffer space 443 and longitudinally abuts against and engages with the first capillary element 441 to prevent a large amount of liquid matrix in the buffer space 443 from flowing back to the first capillary element 441. Alternatively, the isolating element 46 is at least partially located between the buffer space 443 and the first capillary element 441 to prevent a large amount of liquid matrix in the buffer space 443 from flowing back to the first capillary element 441. Alternatively, the isolating element 46 can be used to balance or regulate the flow of the liquid matrix between the buffer space 443 and the first capillary element 441.

[0153] In some embodiments, the isolating element 46 is flexible; for example, the isolating element 46 may be made of flexible silicone, polymer plastic, or other materials. In some embodiments, the isolating element 46 is spaced apart from the second capillary element 442. Alternatively, in yet other embodiments, the isolating element 46 is rigid; for example, it may be made of polymer plastic or the like.

[0154] In some embodiments, the isolation element 46 has a thickness of approximately 0.5 to 3.0 mm.

[0155] In some embodiments, the isolation element 46 is provided with at least one or more notches or through holes 463; in use, the liquid matrix adsorbed by the first capillary element 441 can enter the buffer space 443 through the notches or through holes 463. Alternatively, in some other variations, the isolation element 46 is a mesh with several through holes.

[0156] In some other embodiments, the atomizing mechanism 40 may further include:

[0157] A lead isolation element (not shown) may be located within the second tubular element 45 and closer to the distal end 120 than the atomizing assembly / porous element 47; the lead isolation element is used to provide isolation between the two conductive leads 481 of the heating element 48 to prevent the two conductive leads 481 from short-circuiting.

[0158] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
