With further reference to fig. 3 to 5, the tubular element 11 is internally and equipped with an atomizing assembly, and the tubular element 11 is provided with a plurality of perforations 111 circumferentially spaced for the access of the reservoir 12; whereby the atomizing assembly is in fluid communication with the reservoir 12 through the perforations 111 to receive the liquid matrix. Specifically, the perforations 111 include first perforations 1111 and second perforations 1112 that are spaced apart in the longitudinal direction.
And further referring to fig. 3-5, the atomizing assembly includes:
a liquid guiding element 30, which in this embodiment is flexible; for example, from flexible fibers such as cotton fibers, nonwoven fabrics, sponges, and the like; the liquid guiding element 30 is configured to be annular arranged in the longitudinal direction of the main casing 10; the liquid guiding element 30 is coaxial with the tubular element 11 and is located within the tubular element 11.
In practice, the outer surface of the liquid guiding element 30 in the radial direction is shielded or communicates with the perforations 111, whereby the outer surface of the liquid guiding element 30 is configured as a wicking surface to receive and wick the liquid matrix of the liquid storage chamber 12 through the perforations 111. The inner side surface of the liquid guiding element 30 in the radial direction is configured as an atomizing surface, which is bonded/attached/abutted with the heating element 40; and the liquid matrix is then delivered to the atomizing surface, heated by the heating element 40 to atomize and produce an aerosol which is released.
Referring further to fig. 3-8, in this embodiment the heating element 40 is configured to extend longitudinally of the main housing 10/liquid guiding element 30; the heating element 40 is arranged coaxially with the liquid guiding element 30. In some alternative implementations, the heating element 40 is a resistive heating mesh, resistive heating coil, or the like. In this embodiment, the heating element 40 is a heating element wound from a sheet-like or web-like substrate; the wound heating element 40 is in the circumferential direction non-closed tubular shape, but is tubular with side openings 45 in the longitudinal direction. The heating element 40 has electrode portions 41 located on both sides of the side opening 45, and a mesh-shaped resistive heating portion 42 extending between the electrode portions 41, and a conductive lead 43 connected to the electrode portions 41. Of course, the number of electrode portions 41 and conductive leads 43 are two, one of which serves as the positive terminal and the other of which serves as the negative terminal.
The resistance heating portion 42 is a mesh shape having mesh openings; and the electrode portion 41 is mesh-free.
With further reference to fig. 3-7, the heating element 40 is wound around or secured to the support 50. Correspondingly, the sealing seat 60 is further provided with a plug hole 61 penetrating through the sealing seat 60 along the longitudinal direction, and at least part of the bracket 50 is accommodated or installed in the plug hole 61. Of course, in conventional practice, the inner diameter of the plug aperture 61 near the distal end 120 is smaller than the inner diameter of the portion facing away from the distal end 120, so that there is an abutment step within the plug aperture 61; after assembly, the bracket 50 extends into the plug hole 61 from the side close to the liquid storage cavity 12 and abuts against the step to form a stop.
And further in accordance with fig. 3-10, the shape or configuration of the bracket 50 includes:
a first support portion 51, a support portion 52, a second support portion 53, and a support portion 54 arranged in this order in the axial direction; wherein the first support portion 51, the second support portion 53 and the support portion 54 are each configured in an annular shape, and they are coaxially arranged; and the first support portion 51 and the second support portion 53 have the same outer diameter and/or inner diameter; and, the outer diameter of the supporting portion 54 is larger than the second supporting portion 53. The support portion 52 is an elongated shape extending in the axial direction of the bracket 50, not an annular shape, and serves to connect the first support portion 51 and the second support portion 53 in addition to providing support. After assembly, the first perforation 1111 is opposite to the first support portion 51 in the radial direction of the tubular member 11; the second perforation 1112 is opposite the second support portion 53.
In some implementations, the bracket 50 is made of an electrically insulating rigid material; such as ceramic, PEEK, polytetrafluoroethylene, surface-insulated metals or alloys, etc.
And further referring to fig. 6, the resistance heating portion 42 of the heating element 40 has a heating portion 421 located at a central portion in the axial direction, the heating portion 421 being mainly formed by generating joule heat when a direct current flows therethrough; and the direct current basically flows through the heating part 421; and the heating part 421 is configured to be a mesh shape having a mesh.
And, the resistance heating portion 42 further includes a first tooth 422 extending from the heating portion 421 toward the upper end in the axial direction; and, the resistance heating portion 42 further includes a second tooth portion 423 extending from the heating portion 421 toward the lower end in the axial direction. The first teeth 422 terminate at the upper end of the heating element 40 and are plural in number and discrete from one another; the second teeth 423 terminate at the lower end of the heating element 40 and are plural in number and discrete from each other. When power is supplied, a current flows less through the first teeth 422 and the second teeth 423, and the first teeth 422 and the second teeth 423 are substantially less heated by joules, so that the heating area of the resistance heating portion 42 is mainly located at the heating portion 421.
Correspondingly, in assembly, the first tooth surrounds and is coupled to the first support portion 51 of the bracket 50 and the second tooth 423 surrounds and is coupled to the second support portion 53 of the bracket 50. Then, after assembly, the first tooth 422 is configured to engage the first engagement portion of the bracket 50 and the second tooth or wing 423 is configured to engage the second engagement portion of the bracket 50; the first supporting portion 51 and the second supporting portion 53 of the bracket 50 are respectively supported from the inside at both ends of the heating element 40 after assembly, and the main heating portion 421 of the heating element 40 is exposed to the air passage. And that the bracket 50 is substantially kept away from the main heating portion 421 after assembly, is advantageous in that it prevents a large amount of heat from the heating element 40 from being transferred to the bracket 50.
Or in yet other variations, the heating element 40 is tubular in shape, having an annular first junction at the axial upper end for surrounding and coupling to the first support portion 51 of the bracket 50; the heating element 40 has an annular second coupling portion at the axially lower end for surrounding and coupling to the second support portion 53 of the bracket 50; the heating element 40 also has a heating portion extending between the first bonding portion and the second bonding portion, the heating portion being primarily for resistive heating. Likewise, the heating portion may be of a spiral wire configuration, or of a mesh shape; after assembly, the bracket 50 is kept away from the heating portion, and the heating portion is exposed in the hollow of the bracket 50, so that the heating portion is exposed to the air flow passage.
During the support and assembly of the heating element 40, the liquid guiding element 30, and the tubular element 11 by the support 50, it comprises:
s10, winding the unwound/flat-spread heating element 40 on the first support part 51, the support part 52 and the second support part 53, as shown in FIG. 7; of course, after winding, the extension length of the heating element 40 extends from the first support portion 51 to the second support portion 53. After winding, the first support portion 51 provides support for the heating element 40 from the inside at the upper end of the heating element 40; the second support portion 53 provides support for the heating element 40 from the inside at the lower end portion of the heating element 40. And the electrode portion 41 of the wound heating element 40 is abutted against the support portion 42; and the support portion 42 after winding is projected into the side opening 45 between the electrode portions 41. And the lower end of the heating element 40 is abutted against the support portion 44 after assembly.
And as shown in fig. 7 and 6, the surface of the first support portion 51 is provided with a wire groove 56, and the surface of the second support portion 53 is provided with a wire groove 57; the lead grooves 56 and 57 extend in the axial direction of the bracket 50 and are close to the support portion 52; and the bracket 50 also has a lead slot 58 located in the support portion 54; after assembly, the conductive leads 43 of the heating element 40 are retained in the lead slots 56, 57 and extend out of the support portion 54 through the lead slots 58.
S20, the heating element 60 in fig. 7 is further wrapped or wound around or sleeved with the liquid guiding element 30 and the tubular element 11, i.e. the assembled state in fig. 8. The liquid-guiding element 30 may be a closed loop flexible fiber or be wound from a flexible fiber strip; the lower end of the liquid guiding element 30 abuts against the support portion 44. And as shown in fig. 8, the lower end of the tubular element 11 is wrapped around and around the support portion 54 and forms a support and stop against the positioning boss 541 of the support portion 54.
Specifically, the lower end of the tubular member 11 is provided with a positioning notch 112, and the support portion 54 is provided with a positioning projection 541; in assembly, positioning is provided in the assembly by the engagement of the positioning projections 541 with the positioning notches 112. And, after assembly, the locating projections 541 and locating notches 112 cooperate to prevent rotation or rotation of the tubular member 11 relative to the bracket 50.
Or in still other variations, the detent 112 may be a detent groove, or detent hole, or the like, that provides positioning and resists rotation.
And further referring to fig. 8, the liquid guiding element 30 is flexible; the first portion 31 of the liquid guiding element 30 between the first supporting portion 51 and the tubular element 11 is clamped by the first supporting portion 51 and the tubular element 11 from both inner and outer sides after assembly; and the third portion 33 of the liquid guiding member 30 located between the second supporting portion 53 and the tubular member 11 is clamped by the second supporting portion 53 and the tubular member 11 from both the inside and outside. The first portion 31 and the third portion 33 of the liquid guiding element 30 are relatively compact after assembly, since they are rigidly clamped from both the inner and outer sides, the first portion 31 and the third portion 33. While the second portion 32, which is located between the first portion 31 and the third portion 33, is relatively bulky. And after assembly, the relatively bulky second portion 32 is able to pick up and hold more liquid matrix; while the pressed first portion 31 and the third portion 33 are relatively capable of retaining less liquid matrix, it is advantageous to prevent liquid matrix sucked up in the liquid guiding element 30 from oozing out from the upper end defined by the first portion 31 or from the lower end defined by the first portion 31. Alternatively, it may be advantageous to increase the liquid locking capacity by means of the pressed first portion 31 and third portion 33.
Specifically, the first perforation 1111 is opposite the first portion 31 after assembly; and the second perforation 1112 is opposite the third portion 33. In use, the liquid matrix flowing into the tubular member 11 from the first perforations 1111 is absorbed on the outer surface of the first portion 31 of the liquid guiding member 30 and then is impregnated and transferred longitudinally onto the inner surface of the second portion 32, providing heated atomization onto the heating portion 421 of the heating member 40. The liquid matrix flowing into the tubular member 11 from the second perforation 1111 is absorbed on the outer surface of the third portion 33 of the liquid guiding member 30 and then wets and passes longitudinally to the inner surface of the second portion 32. In the assembled module, the first perforation 1111/the second perforation 1112 of the tubular element 11 are arranged offset from the heating portion 421 of the heating element 40 in the longitudinal direction.
Further, the assembly of the tubular element 11, the atomizing assembly, the support 50 in fig. 8 to form a module is advantageous for the modular production and assembly of the atomizer 100. As further shown in fig. 9, the assembly module of fig. 8 is inserted into the insertion hole 61 of the seal seat 60 to be fixed. Further, after the module of fig. 9 is assembled with the sealing seat 60, the conductive leads 43 pass through the plugging holes 61 to the outside of the sealing seat 60, and are bent into the contact holes 62 to contact or weld with the electrical contacts 21 to form electrical conduction.
And further referring to fig. 10, in this embodiment, the inner surface of the plug hole 61 is provided with an air groove 64 extending in the longitudinal direction; the air groove 64 has a depth of about 0.2-2 mm and a width of about 0.5-2 mm; an air passage is defined between the outer surface of the tubular element 11 and the air groove 64 after assembly. When the negative pressure in the liquid storage chamber 12 exceeds the threshold value, the external air introduced from the air inlet hole 23 can enter the liquid storage chamber 12 along the air passage defined by the air groove 64 as indicated by an arrow R4 in fig. 10 to relieve the negative pressure in the liquid storage chamber 12.
Or in still other variations, as shown in figures 13-10, the endcap 20 is also provided with longitudinally extending extension arms 24; extension arm 24 is convex with respect to the rest of endcap 20. Extension arm 24 is substantially in the shape of an elongated cylinder, extension arm 24 having a length of about 3-8 mm and an outer diameter of about 1-3 mm. Correspondingly, the sealing seat 60 is provided with a through hole 63 penetrating or extending to the upper end face; after assembly, extension arm 24 is inserted or extended into throughbore 63. Similarly, an air passage for replenishing air into the reservoir 12 is defined between the extension arm 24 and the through hole 63; for example, by providing axially extending air grooves on the outer surface of the extension arm 24 and/or the inner surface of the through hole 63; and defines an air passage between the inner surface of the through hole 63 and the extension arm 24 by the air groove.
With further reference to fig. 4-10, at least a portion of the lower end of the tubular member 11 is at least partially inserted into the socket 61 with the bracket 50 after assembly. And, the upper end of the tubular member 11 is further provided with a positioning notch 113 for the air supply pipe 13 to be inserted from the upper end of the tubular member 11 and to be positioned in cooperation with the positioning notch 113. And in a preferred embodiment, the air tube 13 is inserted into the tubular element 11 by means of riveting or a tight fit, etc., so that they are tightly joined and thus sealed; is advantageous for preventing leakage of the liquid matrix from between them.
During the suction process after assembly, as shown by arrow R2 in fig. 5, air entering through the air inlet 23 of the end cap 20 enters the hollow of the bracket 50 through the insertion hole 61 of the sealing seat 60, and aerosol released by carrying the atomizing surface after passing through the bracket 50 is output from the tubular element 11 and the air tube 13 to the air suction port 130 to be sucked. The air flow path or air flow channel during the suction process is through the bracket 50. Of course, the air flow path or air flow channel is also through the tubular or annular or wound cylindrical liquid guiding element 30. And the air flow path or air flow channel is through the tubular or annular or coiled cylindrical heating element 40.
And in practice the complete air flow path shown by arrow R2 is defined by the seal 60, the support 50, the heating element 40, the tubular element 11 and the air duct 13 together to form a flow path for air from the air inlet 23 through the heating element 40 to the air inlet 130 for aerosol output to the air inlet 130. And, after assembly, the heating portion 421 of the resistive heating portion 42 of the heating element 40 is exposed to the airflow path to release the aerosol to the airflow path. And, the first teeth 422 of the resistance heating portion 42 are shielded by the first support portion 51 of the holder 50, and the second teeth 423 of the resistance heating portion 42 are shielded by the second support portion 53 of the holder 50, which are not exposed to the air flow passage, or which are isolated from the air flow passage.
Further FIGS. 11 and 12 show schematic views of a still further embodiment of a holder 50a, heating element 40 and liquid guiding element 30 before and after assembly; in this embodiment, the stand 50a includes:
the first support portion 51a, the support portion 52a, and the second support portion 53a and the support portion 54a are arranged in this order in the longitudinal direction. Wherein the first supporting portion 51a, the second supporting portion 53a and the supporting portion 54a are annular in shape; and, a support portion 52a for connecting the first support portion 51a and the second support portion 53a, and the support portion 52a is elongated; and, the outer diameter of the support portion 54a is larger than the outer diameter of the first support portion 51a and/or the second support portion 53 a. And, after assembly, the first teeth 422 of the heating element 40 are wrapped around and bonded to the first support portion 51a and the second teeth 423 are wrapped around and bonded to the second support portion 53 a.
And further, the first support portion 51a of the bracket 50a is provided with one or more protrusions 511a extending radially outwardly; the one or more protrusions 511a are circumferentially arranged around the first support portion 51 a. And, after assembly, the one or more protrusions 511a are against the inner surface of the tubular element 11; such that the tubular member 11 is substantially abutted against the first support portion 51a, avoiding that the spacing between the tubular member 11 and the first support portion 51a allows the stent 50a to loosen or rock within the tubular member 11. And, when the liquid guide member 30 is wrapped around and bonded to the heating element 40, the liquid guide member 30 and/or the upper end of the heating element 40 form a stop against the projection 511a, which is advantageous for stably assembling and fixing the heating element 40/liquid guide member 30.
Fig. 13 to 15 further illustrate schematic views of a further embodiment of the seal holder 60b, the tubular element 11b, the bracket 50b, the liquid guiding element 30b and the heating element 40 before and after assembly; in this embodiment, the liquid guide member 30b surrounds and is coupled to the heating element 40 and is supported internally by the bracket 50 b. And in this embodiment, the tubular element 11b is provided with a first notch 114b extending longitudinally to the lower end; and the portion 31b of the liquid guiding element 30b is exposed in the first notch 114b after assembly. And in an embodiment, the portion 31b of the liquid guiding element 30b is convex; in assembly, as indicated by arrow R5 in fig. 3, the pass-through portion 31b is aligned with the first notch 114b to provide positioning during assembly.
Or in still other embodiments, the annular liquid guide member 30b is formed by wrapping a flexible sheet-like fibrous material, such as sheet-like cotton fibers, around the support 50b and/or the heating element 40; when the wound liquid guiding element 30b is kept with the fiber material with the excessive length; in assembly, the excess length of fibrous material is assembled in alignment with the first notch 114b of the tubular member 11b, and after assembly the excess length of fibrous material protrudes from the first notch 114b out of the tubular member 11 b; the excess length of fibrous material extending beyond the tubular member 11b is then trimmed by scissors to complete the assembly. And the liquid guiding element 30b is formed to be exposed from the portion 31b of the first notch 114b.
And correspondingly, a wrap portion 65b disposed on a first side of the seal seat 60b toward the proximal end 110; for wrapping and covering the first notch 114b of the tubular member 11b by the wrapping portion 65b when the tubular member 11b, the liquid guiding member 30b, are fitted into the insertion hole 61b of the seal housing 60 b.
Specifically, the wrapping portion 65b is substantially annular in shape surrounding the insertion hole 61b, and has a convex edge 651b extending in the longitudinal direction; after assembly, the tubular element 11b is surrounded and wrapped by the wrapping portion 65b, and the wrapping portion 65b avoids the perforations 111b in the tubular element 11b. And, after assembly, the first notch 114b of the tubular element 11b is jointly obscured and covered by the wrapping 65b and the ledge 651 b.
And, a space is provided between the wrapping portion 65b and the seal seat 60 b; after assembly, the perforations 111b of the portion of the tubular member 11b are located within the space between the wrapping portion 65b and the seal seat 60 b.
Fig. 16 and 17 show schematic views of a nebulizer 100c of yet another embodiment in which the nebulizer 100c comprises:
a main casing 10c, the proximal end 110c of the main casing 10c having an air inlet 130c; the main housing 10c is open at a distal end facing away from the proximal end 110c and is provided with an end cap 20c;
a gas tube 13c extending from the suction port 130c away from the proximal end 110c within the main housing 10 c; the air tube 13c is integrally molded with the main housing 10c from a moldable material such as an organic polymer or the like;
a tubular member 11c coaxially arranged with the air tube 13 c; and the air tube 13c is at least partially inserted into the tubular element 11c and forms a seal with the tubular element 11c by interference fit; the tubular member 11c may be made of a metal or alloy material such as stainless steel;
a reservoir 12c for storing a liquid matrix, located within the main housing 10c and surrounding the air tube 13c and the tubular member 11c;
a flexible seal 60c for closing the distally facing open end of the reservoir 12c on the one hand and the seal 60c for providing a seal between the end cap 20c and the main housing 10c to prevent seepage of the liquid matrix on the other hand; and, the tubular element 11c is at least partially inserted into the sealing seat 60c for assembly and fixation;
The atomizing assembly comprises a liquid guiding element 30c and a heating element 40c, located within the tubular element 11c, for receiving the liquid matrix in the liquid reservoir 12c through perforations in the tubular element 11 c;

electrical contacts 21c extend from the end cap 20c into the main housing 10c for powering the heating element 40 c.
As shown in fig. 16 and 17, the end of the trachea 13c facing away from the proximal end 110c has a reduced outer diameter portion 133c; further, when the trachea 13c is inserted into the tubular member 11c, the reduced outer diameter portion 133c and the tubular member 11c define a collection space 134c therebetween. And, the collection space 134c, on the one hand, barbs the reduced outer diameter portion 133c within the tubular member 11c, thereby preventing the liquid matrix of the liquid guiding member 30c from flowing along the inner surface of the tubular member 11c toward the trachea 13c; on the other hand, the collection space 134c forms a storage space for aerosol condensate for adsorbing and holding the aerosol condensate flowing down from the inner surface of the air tube 13c by capillary action.
In some embodiments, the collection space 134c defined between the air tube 13c and the tubular element 11c has a length of about 1-5 mm; and, the collecting space 134c has a width of about 0.3 to 3 mm.
As shown in fig. 17, the trachea 13c is provided with a second indentation 131c on the end facing away from the proximal end 110c, and a protrusion 132c adjacent to the second indentation 131 c; by capillary action of the second indentations 131c to adsorb aerosol condensate flowing down from the inner surface of the air tube 13 c. The aerosol condensate adsorbed in the second indentation 131c is then guided into the collecting space 134c by means of a projection 132c arranged along the longitudinal extension of the air tube 13c, as indicated by arrow R3 in fig. 17.
In some embodiments, the second notch 131c has a length of about 1-3 mm and a width of 0.5-2 mm. In some embodiments, protrusion 132c has a length of 1-3 mm and a width of 0.5-2 mm.
According to fig. 16, when the air tube 13c is inserted into the tubular element 11c, the atomizing assembly is non-contacting with the air tube 13c with a space therebetween. For example, in the embodiment shown in fig. 16, the liquid guiding element 30c of the atomizing assembly is non-contacting with the air tube 13c and has a distance d20; the spacing d20 is greater than 2mm to prevent the liquid matrix of the liquid-directing element 30c from being capillary-absorbed into the collection space 134 c.
Fig. 18 shows a schematic view of a nebulizer 100d of yet another embodiment, the nebulizer 100d of this embodiment comprising:
A main casing 10d;
a gas tube 13d for outputting aerosol;
a tubular element 11d extending within the reservoir 12 c;
a liquid guiding element 30d located within the tubular element 11 d; an outer surface of the liquid guiding member 30d in the radial direction for sucking the liquid matrix from the liquid storage chamber 12 c;
a heating element 40d arranged in a cylindrical shape extending in the longitudinal direction of the tubular element 11d, being bonded to the inner surface of the liquid guiding element 30d for heating at least part of the liquid matrix within the liquid guiding element 30d to generate an aerosol;
a bracket 50d is positioned at least partially within the heating element 40d for providing support to the heating element 40d from inside the heating element 40 d.
As shown in fig. 19 and 20, the shape or configuration of the bracket 50d includes:
a first supporting portion 51d, a supporting portion 52d, a second supporting portion 53d, and a supporting portion 54d arranged in this order in the axial direction; wherein the first support portion 51d, the second support portion 53d, and the support portion 54d are each configured in an annular shape, and they are coaxially arranged; and the first support portion 51d and the second support portion 53d have the same outer diameter and/or inner diameter; and, the outer diameter of the supporting portion 54d is larger than the second supporting portion 53d. The support portion 52d is an elongated shape extending in the axial direction of the bracket 50d, not an annular shape, and serves to connect the first support portion 51d and the second support portion 53d in addition to providing support.
According to fig. 19 and 20, the heating element 40d comprises a side opening 45d extending longitudinally through the heating element 40 d; such that the first wound heating elements 40d arranged at intervals in the circumferential direction are non-closed cylinders in the circumferential direction. The heating element 40d has electrode portions 41d located on both sides of the side opening 45d, and a mesh-like resistive heating portion 42d located between the electrode portions 41d, and a conductive lead 43d connected to the electrode portions 41 d. The resistive heating portion 42d is provided with a plurality of mesh holes so that the resistive heating portion 42d is net-shaped. The electrode portion 41d is dense, and there is no mesh on the electrode portion 41 d.
The resistance heating portion 42d includes a heating portion 421d, a first tooth portion 422d extending from the heating portion 421d in the longitudinal direction toward the first end, and a second tooth portion 423d extending from the heating portion 421d in the longitudinal direction toward the second end. In assembly, the first teeth 422d surround and are coupled to the first support portion 51d of the bracket 50d and the second teeth 423d surround and are coupled to the second support portion 53d of the bracket 50 d. The first supporting portion 51d and the second supporting portion 53d of the bracket 50d are respectively supported from the inside at both ends of the heating element 40d after assembly, and the main heating portion 421d of the heating element 40d is exposed to the air passage. And that the bracket 50d is substantially shielded from the primary heating portion 421d after assembly, is advantageous in preventing substantial heat transfer from the heating element 40d to the bracket 50 d. And after assembly, the conductive leads 43d of the heating element 40d rest against the support portions 52d of the bracket 50 d.
As shown in fig. 19 and 20, an air guide structure 59d for guiding an air flow, such as a protrusion formed on the inner surface of the support portion 52d, is disposed on the inner surface of the support portion 52d of the bracket 50 d. In some embodiments, heating element 40d has an inner diameter of about 4-8 mm; the air guiding structure 59d configured as a protrusion has a height of about 3 to 5 mm. In use, the air directing structure 59d is used to direct air entering the holder 50d and/or the heating element 40d towards the resistive heating portion 42d to carry as much aerosol as possible for later output. As shown in fig. 18 and 19 specifically by arrow R2, it is advantageous to flow air over the surface of the resistive heating portion 42d as much as possible to carry aerosol away because the air guiding structure 59d is blocked by the air guiding structure 59d and thereby bypasses the air guiding structure 59d to the resistive heating portion 42d when the air taken in by the air intake 23d enters the holder 50d and/or the heating element 40 d.
In fig. 19, the surface of the air guiding structure 59d facing or near the second support portion 53d is obliquely arranged; it is advantageous for the air to flow toward the resistance heating portion 42 d.
In some embodiments, the air guiding structure 59d is opposite the heating portion 421d of the resistive heating portion 42 d.
According to fig. 19 and 20, the conductive lead 43d of the heating element 40d is longer relative to the first tooth 422d of the resistive heating portion 42 d. And, the conductive lead 43d has an elongated portion 431d protruding or higher than the first tooth 422d of the resistance heating portion 42 d. After assembly, the front end of the elongated portion 431d of the conductive lead 43d is flush with the end of the first support portion 51d of the bracket 50 d; a kind of electronic device with a high-pressure air-conditioning system. The first tooth 422d only partially surrounds and engages the first support portion 51d and has a spacing d21 from the end of the first support portion 51d of the bracket 50 d; in some embodiments, the spacing d21 is about 2-5 mm. And the length of the elongated portion 431d of the conductive lead 43d is the same as the size of the space d21, about 2 to 5mm. In practice, the front end of the elongated portion 431d extending through the conductive lead 43d to the front end of the first support portion 51d of the bracket 50d is flush, which is advantageous in terms of positioning and lifting uniformity in assembly. And, forming the first tooth 422d with a distance d21 from the front end portion of the elongated portion 431d and/or the front end portion of the first support portion 51d of the bracket 50d is advantageous in preventing a large amount of temperature or heat from being transferred to their front end portions.
Similarly, the second tooth 423d of the resistance heating portion 42d of this embodiment only partially surrounds the second support portion 53d of the bracket 50 d; and the second tooth 423d of the resistance heating portion 42d does not abut against the supporting portion 54 d. After assembly, the second teeth 423d of the resistance heating portion 42d have a spacing d22 from the support portion 54 d; in some embodiments, the spacing d22 is about 2-5 mm.

In fig. 19, the length dimension of the elongated portion 432d is longer than the dimension of the elongated portion 431 d. And after assembly, the elongated portion 432d is connected to the electrical contact 21d by bending to form an electrical conductor to conduct current across the heating element 40 d.
As shown in fig. 18, the atomizer 100d further includes:
a flexible sealing element 140d is arranged between the tubular element 11d and the trachea 13d, thereby providing a seal therebetween.
