Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning.

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

During assembly, end cap 20 is inserted or extended into spacing space 630 to fit against. And, when assembled, the peripheral sidewall 610 partially surrounds or encircles the end cap 20 and is supported from the inside by the end cap 20 to provide a seal between the end cap 20 and the main housing 10. And when assembled, the sealing portion 620 is extended or received within the end cap 20.

And the sealing seat 60 is provided with a contact hole 62 which penetrates along the axial direction or the longitudinal direction; when assembled, the second electrical contact 21 extends through or into the contact aperture 62. And as shown in figure 5, when assembled, the second electrical contact 21 extends through the contact aperture 62 and into the reservoir 12. Preferably, the second electrical contact 21 is flush with the surface of the sealing seat 60. The second electrical contact 21 does not protrude or recess with respect to the surface of the sealing seat 60.

As further shown in fig. 3 to 5, the tubular element 11 is provided with an atomizing assembly and a plurality of liquid guide holes 111 arranged at intervals along the circumferential direction are formed in the tubular element 11 for the liquid storage chamber 12 to enter; the atomizing assembly is thus in fluid communication with the reservoir 12 through the fluid-conducting aperture 111 to receive the liquid substrate.

And further with reference to fig. 3-5, the atomizing assembly includes:

a drainage element 30, flexible in this embodiment; for example, from flexible fibers such as cotton, nonwoven, sponge, etc.; the liquid guiding member 30 is configured in a ring shape arranged in the longitudinal direction of the main casing 10; the drainage 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 member 30 in the radial direction is in communication with the liquid guiding hole 111, and the outer surface of the liquid guiding member 30 is configured as a liquid absorbing surface to receive and absorb the liquid matrix of the liquid storage chamber 12 through the liquid guiding hole 111. The inner surface of the liquid guiding element 30 in the radial direction is configured as an atomizing surface, which is bonded/conformed/abutted with the heating element 40; and the liquid substrate is delivered to the atomizing surface, the aerosol is generated and released by heating the aerosol by the heating element 40.

As further shown in fig. 3-6, in this embodiment the heating element 40 is configured to extend longitudinally along the main housing 10/wicking element 30; heating element 40 is coaxially disposed with liquid conducting 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 by a sheet-like or net-like substrate; the coiled heating element 40 is not a closed tube in the circumferential direction, but a tube shape having a side opening 45 in the longitudinal direction. The heating element 40 has electrode portions 41 on both sides of the side opening 45, and a mesh-like resistance heat generating portion 42 extending between the electrode portions 41, and an electrically conductive lead 43 connected to the electrode portions 41. Of course, the number of the electrode portions 41 and the electrically conductive leads 43 is two, one of which serves as a positive terminal and the other serves as a negative terminal.

The resistance heat generating portion 42 is a mesh shape having mesh holes; and the electrode portion 41 is mesh-free.

As further shown in fig. 3-7, the heating element 40 is wrapped around or secured to the bracket 50. Correspondingly, the sealing seat 60 is further provided with a bracket hole 61 penetrating the sealing seat 60 along the longitudinal direction, and the bracket 50 is accommodated or installed in the bracket hole 61. Of course in conventional practice, the inner diameter of the holder bore 61 is non-constant, specifically the inner diameter of the holder bore 61 in the portion near the distal end 120 is smaller than the inner diameter in the portion away from the distal end 120, so as to have an abutment step within the holder bore 61; after assembly, the bracket 50 extends into the bracket hole 61 from one side close to the liquid storage cavity 12 and then abuts against the step to form a stop.

And further with reference to fig. 3-10, the shape or configuration of the stent 50 includes:

a support portion 51, a support portion 52, a support portion 53, a support portion 54, and a support portion 55 arranged in this order in the axial direction; wherein the support portion 51, the support portion 53, the support portion 54, and the support portion 55 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 support portion 54 has a larger outer diameter than the support portion 53, and the support portion 55 has a larger outer diameter than the support portion 54.

The support portion 52 is an elongated shape extending in the axial direction of the holder 50, not a ring shape, and serves to connect the support portion 51 and the support portion 53 in addition to providing support.

In some implementations, the bracket 50 is made of an electrically insulating rigid material; such as ceramics, PEEK, teflon, surface insulating metals or alloys, etc.

And further referring to fig. 6, the resistance heat generating portion 42 of the heating element 40 has a heat generating portion 421 located at a central portion in the axial direction, the heat generating portion 421 mainly generating joule heat when a direct current flows therethrough; and the direct current basically mainly flows through the heat generating portion 421; and the heat generating portion 421 is configured in a mesh shape having mesh holes.

And, the resistance heat generating portion 42 further includes a first tooth portion or wing portion 422 extending from the heat generating portion 421 toward the upper end in the axial direction; and, the resistance heat generating portion 42 further includes a second tooth portion or wing portion 423 extending from the heat generating portion 421 toward the lower end in the axial direction. The first teeth or wings 422 terminate at the upper end of the heating element 40 and are plural and discrete from one another in number; the second teeth or wings 423 terminate at the lower end of the heating element 40 and are plural and discrete from each other. When power is supplied, a current flows less through the first tooth or wing portion 422 and the second tooth or wing portion 423, and the first tooth or wing portion 422 and the second tooth or wing portion 423 generate substantially less heat by joule, so that the heat generation region of the resistance heat generation portion 42 is mainly located at the heat generation portion 421.

Accordingly, in assembly, the first teeth or wings 422 surround and are coupled to the support portion 51 of the bracket 50, and the second teeth or wings 423 surround and are coupled to the support portion 53 of the bracket 50.

portions

51 and 53 of the supporter 50 are supported from the inside at both ends of the heating element 40, respectively, after assembly, and the main heat generating portion 421 of the heating element 40 is exposed to the air passage. And, when assembled, the holder 50 is substantially kept away from the main heat generating portion 421, which is advantageous for preventing the heat of the heating element 40 from being largely transferred to the holder 50.

Or in a further variant, the heating element 40 is tubular in shape, having at the upper end in the axial direction a first coupling portion in the form of a ring, intended to surround and couple to the support portion 51 of the support 50; the heating element 40 has a ring-shaped second coupling portion at a lower end in the axial direction for surrounding and coupling to the supporting portion 53 of the supporter 50; the heating element 40 also has a heat generating portion extending between the first joining portion and the second joining portion, the heat generating portion being mainly used for resistance heat generation. Likewise, the heat generating portion may be of a spiral wire configuration, or of a mesh shape; after assembly, the bracket 50 keeps away from the heat generating portion, and the heat generating portion is exposed in the hollow of the bracket 50, so that the heat generating portion is exposed in the airflow channel.

s10, winding the unwound/flat-unwound heating element 40 on the support portion 51, the support portion 52, and the support portion 53, as shown in fig. 7; of course, after winding, the extension length of the heating element 40 extends from the support portion 51 to the support portion 53. After winding, the support portion 51 provides support to the heating element 40 from the inside at the upper end portion of the heating element 40; the support portion 53 provides support to the heating element 40 from the inside at the lower end portion of the heating element 40. And, the electrode portion 41 of the heating element 40 after winding is abutted against the support portion 42; and the coiled rear support portion 42 is extended into the side opening 45 between the electrode portions 41.

S30, a lead fastener 70 is further installed at the lower end of the bracket 50 in fig. 8 to fasten or abut the conductive leads 43 against the inner wall of the support portion 45, thereby preventing them from being bent or entangled or contacting to cause a short circuit or the like. And as shown in fig. 9, the wire guides 58 are formed at least partially on the inner surface of the support portion 55.

S40, the tubular element 11 is further sleeved outside the liquid guiding element 30 in fig. 9, i.e. the assembled state of fig. 10 is formed. And according to fig. 10, the lower end of the tubular element 11 is around and sleeved on the support portion 54 and forms a support and stop against the support portion 55. Meanwhile, the bracket 50 further has a positioning projection 541 extending from the support portion 55 toward the support portion 54, and the lower end of the tubular member 11 is provided with a positioning notch 112; in assembly, positioning is provided in assembly by the mating of the positioning projections 541 and the positioning notches 112. And, after assembly, the positioning projections 541 and the positioning notches 112 cooperate to prevent rotation or pivoting of the tubular member 11 relative to the holder 50.

Or in yet other variations, the positioning notch 112 may be a positioning groove, a positioning hole, or the like that provides positioning and prevents rotation.

And further to fig. 10, in the assembled module, the liquid-conducting holes 111 of the tubular element 11 in the radial direction are opposite to the resistance heat generating portions 42 of the heating element 40; the supporting strength of the resistance heat generating portion 42 of the heating element 40 at the portion of the liquid guiding member 30 opposite to the liquid guiding hole 111 is made stronger to achieve better proximity control of liquid transfer.

Further, the assembly of the tubular member 11, atomizing assembly, bracket 50, and lead wire fastener 70 into a module in fig. 10 is advantageous for modular production and assembly of the atomizer 100. And then the assembly module shown in fig. 10 is inserted into the bracket hole 61 of the sealing seat 60 and fixed. Further, after the module of fig. 10 is assembled with the sealing seat 60, the conductive leads 43 pass through the bracket holes 61 to the outside of the sealing seat 60, and are bent into the contact holes 62 to contact or be welded with the second electrical contacts 21 for electrical conduction.

And further in accordance with a preferred embodiment as shown in fig. 10, a wicking element 30 made of a flexible fabric or sponge is squeezed or compressed from both the inside and outside by the tubular member 11 and the heating element 40/holder 50, thereby stably restraining and retaining the wicking element 30 between the tubular member 11 and the heating element 40/holder 50.
