For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there is a so-called electronic atomizing device. These devices typically contain a liquid that is heated to vaporize it, producing an inhalable aerosol. The liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol).

At the same time, an air inlet 23 is provided in the end cap 20 for the entry of external air into the atomizer 100 during suction.

Referring to fig. 3 to 5, the inside of the main housing 10 is provided with a liquid storage chamber 12 for storing a liquid substrate, and an atomizing assembly for sucking the liquid substrate from the liquid storage chamber 12 and heating the atomized liquid substrate. Wherein the atomizing assembly generally includes a capillary liquid guide element for drawing the liquid matrix, and a heating element coupled to the liquid guide element that heats at least a portion of the liquid matrix of the liquid guide element to generate an aerosol during energization.

After assembly, a reservoir 12 for storing liquid matrix is defined by the outer surface of the air tube 13, the outer surface of the tubular element 11 and the inner wall of the main housing 10.

In the embodiment shown in fig. 3-5, the reservoir 12 defined within the main housing 10 is closed at the proximal end 110 by the main housing 10; while the end of the reservoir 12 facing the distal end 120 is open. Further, as shown in fig. 3 to 5, the atomizer 100 further includes:

The flexible seal 60 may be made of a flexible material such as silicone, thermoplastic elastomer, or the like. And after assembly, the flexible seal housing 60 is at least partially received within the end cap 20 to provide support by the end cap 20.

Referring to fig. 3 to 5, the tubular element 11 is internally and fitted 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.

Referring to fig. 3 to 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. Or in still other variations, the liquid-directing element 30 may also include a rigid porous body element or the like, such as a porous ceramic or porous glass or the like.

In an embodiment, 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 liquid absorbing surface for receiving and absorbing the liquid matrix of the liquid reservoir 12 through the perforations 111, as indicated by arrow R1 in fig. 5. 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 to fig. 3-7, 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 embodiments, 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 conductive pins 41 and 42 located on both sides of the side opening 45, and a mesh-shaped resistive heating portion 43 located between the conductive pins 41 and 42. The resistance heating portion 43 is a mesh shape having mesh openings.

Referring 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 embodiments, 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, thereby having 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.

As shown in fig. 3-7, the shape or configuration of the bracket 50 includes:

a support portion 51, a support portion 52, a support portion 53, and a support portion 54 arranged in this order in the axial direction; wherein the support portion 51, the support portion 53, and the support portion 54 are each configured in an annular shape, and they are coaxially arranged; and the support portion 51 and the 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 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 support portion 51 and the support portion 53 in addition to providing support.

In some embodiments, the support 50 is made of an electrically insulating rigid material; such as ceramic, PEEK, polytetrafluoroethylene, surface-insulated metals or alloys such as stainless steel, etc.

Referring to fig. 6 and 7, the resistance heating portion 43 of the heating element 40 has a heating portion 431 located at a central portion in the axial direction, the heating portion 431 being mainly formed by generating joule heat when direct current flows therethrough; and the direct current basically flows through the heating part 431; and the heating part 431 is configured to be a mesh shape having a mesh.

And, the resistance heating portion 43 further includes a first tooth 432 extending from the heating portion 431 toward the upper end in the axial direction; and, the resistance heating portion 43 further includes a second tooth 433 extending from the heating portion 431 toward the lower end in the axial direction. The first teeth 432 terminate at the upper end of the heating element 40 and are plural in number and discrete from one another; the second teeth 433 terminate at the lower end of the heating element 40 and are plural in number and discrete from one another. When power is supplied, a current flows less through the first tooth 432 and the second tooth 433, and the first tooth 432 and the second tooth 433 are substantially less heated by joules, so that the heating region of the resistance heating portion 43 is mainly located at the heating portion 431.

Correspondingly, in assembly, the first tooth surrounds and engages the support portion 51 of the bracket 50 and the second tooth 433 surrounds and engages the support portion 53 of the bracket 50. Then, after assembly, the first tooth 432 is configured to engage the first engagement portion of the bracket 50 and the second tooth 433 is configured to engage the second engagement portion of the bracket 50; the supporting portions 51 and 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 431 of the heating element 40 is exposed to the air passage. And that the bracket 50 is substantially shielded from the main heating portion 431 after assembly, is advantageous in preventing substantial transfer of heat from the heating element 40 to the bracket 50. And after assembly, the conductive pins 41 and 42 of the heating element 40 respectively abut against the support portion 52 from both sides.

As shown in fig. 6 and 7, in the longitudinal direction of the heating element 40, the conductive pin 41 has an elongated portion 411 extending beyond the upper end of the resistance heating portion 43, and the conductive pin 42 has an elongated portion 421 extending beyond the upper end of the resistance heating portion 43. The elongated portion 411 and the elongated portion 421 have a length of about 2 to 5mm. After assembly, the elongated portion 411 of the conductive pin 41 and/or the elongated portion 421 of the conductive pin 42 are extended to the upper end of the supporting portion 51 of the bracket 50, or the elongated portion 411 of the conductive pin 41 and/or the elongated portion 421 of the conductive pin 42 are flush with the upper end of the bracket 50. And, conductive pins 41 and/or conductive pins 42 extend beyond the lower end of bracket 50. And, after assembly, the first tooth 432 of the resistance heating portion 43 has a distance d21 from the upper end of the bracket 50 of about 2 to 5mm; the second tooth 433 of the resistance heating portion 43 has a distance d22 from the lower end of the holder 50 of about 2 to 5mm.

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 support portion 51 of the bracket 50; the heating element 40 has an annular second coupling portion at the lower end in the axial direction for surrounding and coupling to the supporting 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.

After assembly, the atomizing assembly is completely contained within the tubular member 11; and the lower end of the tubular element 11 may rest against the support portion 54 of the bracket 50. Alternatively, the lower end of the tubular member 11 may have a locating notch 1122 on the support portion 54 of the bracket 50 with a locating detent projection disposed thereon which provides for locating during assembly by their engagement. And, after assembly, the detent notch 112 and detent catch 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.

In the embodiment of fig. 3-8, the end cap 20 is further provided with a longitudinally extending blocking element 24; the occlusion element 24 is protruding relative to the rest of the end cap 20. The occlusion element 24 is substantially in the shape of an elongated cylinder, the occlusion element 24 having a length of about 3-8 mm and an outer diameter of about 1-3 mm. Accordingly, the seal seat 60 is provided with a liquid injection passage 67 disposed toward the end cap 20; after assembly, the occlusion element 24 is inserted or extended into the fluid injection channel 67 to stably retain the seal mount 60 to the end cap 20. And in an embodiment, the priming channel 67 is through the seal housing 60.

In fig. 3 to 8, the plug aperture 61 of the seal seat 60 defines a port 66 facing the end cap 20; and the port 66 is opposite or in communication with the air inlet 23 of the end cap 20 for air delivery to the atomizing assembly.

During the suction process after assembly, as indicated by arrow R2 in fig. 5, air entering through the air inlet 23 of the end cap 20 is then transported through the port 66 of the seal 60 and out of the tubular member 11 and the air tube 13 through the hollow rear carrying atomizing face of the holder 50 to the suction port 130 for inhalation. 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 the embodiment shown by arrow R2, the complete airflow path 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 431 of the resistive heating portion 43 of the heating element 40 is exposed to the airflow path to release the aerosol to the airflow path.

And, the electrical connection element 70 is rigid.

As shown in fig. 3 to 10, the electrical connection element 70 is arranged between the sealing seat 60 and the end cap 20. After assembly, the sealing seat 60 is provided with a number of receiving grooves or the like for at least partially holding the electrical connection element 70.

In some embodiments, the electrical connection element 70 may comprise a conductive metal plate or sheet, or the like. In use, the electrical contact 21 makes electrical conduction against the electrical connection element 70 and the conductive pin 41/42 of the heating element 40 makes electrical conduction against or soldered to the electrical connection element 70, thereby establishing an electrical connection of the electrical contact 21 with the conductive pin 41/42 through the electrical connection element 70.

In the embodiment shown in fig. 3 to 10, the electrical connection element 70 comprises:

an electrically insulating substrate 71 having a laminated structure, which is configured to be a sheet-like or plate-like shape having a laminated structure formed by laminating a plurality of sheets, or may be an arbitrary shape; the electrically insulating substrate 71 includes an upper surface 710 and a lower surface 720 that are opposite; when assembled, upper surface 710 is adjacent to or facing seal housing 60 and lower surface 720 is adjacent to or facing end cap 20.

In some embodiments, the electrically insulating substrate 71 is rigid or hard.

In some embodiments, the electrically insulating substrate 71 is defined by a sheet of material. In still further embodiments, the electrically insulating substrate 71 is defined by one or more layers of sheet material by lamination; for example, the electrically insulating substrate 71 may comprise at least two or more sheets laminated; specifically, in some embodiments, the electrically insulating substrate 71 may include at least one of a phenolic laminate formed by laminating at least two sheets, an epoxy laminate, a polyester glass mat laminate, an epoxy glass mat laminate, and the like.

In some embodiments, electrically insulating substrate 71 has defined thereon:

the air hole 66 is mainly used for passing through the air inlet 23 to enter the port 66 of the sealing seat 60.

In some embodiments, the electrically insulating substrate 71 formed by lamination of the multiwall sheet can have a thickness of about 1-10 mm.

In the embodiment shown in fig. 3-10, the electrical connection element 70 further comprises:

a conductive material layer 741 and a conductive material layer 742 formed on the lower surface 720; the conductive material layer 741 and the conductive material layer 742 are separate, and they are not connected to each other; after assembly, conductive pin 41 is bent against or welded to one of conductive material layer 741 and conductive material layer 742 after passing through air hole 66, and conductive pin 42 is bent against or welded to the other of conductive material layer 741 and conductive material layer 742 after passing through air hole 66; and one of the electrical contacts 21 abuts against one of the conductive material layers 741 and 742 and the other abuts against the other of the conductive material layers 741 and 742.

In practice, conductive material layer 741 and conductive material layer 742 are patterned conductive patterns formed by spraying or depositing or printing conductive material on upper surface 710; and, the conductive material layer 741 and the conductive material layer 742 may be conductive patterns having any regular or irregular shape. And, the conductive material layers 741 and 742 may be a meander, or serpentine trace pattern.

In an embodiment, the layer of conductive material 741 is disposed proximate a first side of the electrical connection member 70 in the length direction and the layer of conductive material 742 is disposed proximate a second side of the electrical connection member 70 in the length direction. And, the conductive material layer 741 and the conductive material layer 742 avoid or surround the air holes 711. And, the conductive material layer 741 and the conductive material layer 742 are symmetrically arranged along the length direction of the electric connection member 70.

a conductive material layer 731 and a conductive material layer 732 formed on the upper surface 710; and, the conductive material layer 731 and the conductive material layer 732 are substantially symmetrically arranged with the conductive material layer 741 and the conductive material layer 742 on the lower surface 720. By symmetrically arranging the conductive material layers 741 and 742, 731 and 732 on both surfaces of the electrical connection element 70, it is not necessary to identify the mounting direction of the electrical connection element 70 in the assembly, i.e. no foolproof is required. It is advantageous to reduce the direction recognition process to improve the mounting efficiency in the assembly. The electrical connection element 70 has a rotational symmetry turned 180 degrees around the thickness direction, which is advantageous for mounting.
