Description

Atomizer and electronic atomization device

Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an atomizer and an electronic atomization device.

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 the compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol provision articles, for example, so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize it, producing an inhalable aerosol.

A portion 632b formed by extension of portion 631 b; and, the portion 632b extends along the length of the top wall 6110 b; and, the portion 632b is arcuately curved.

The height of the protrusions such as the protruding edge 63b is 0.6-1.5 mm.

Further in practice, a fluid passageway is defined between the portions 631b and 632b of the ledge 63b and the peripheral side wall 6220b between the second fluid transfer apertures 62b and the first fluid transfer apertures 52 b.

And the second liquid guiding holes 62b and the first liquid guiding holes 52b are respectively located at both sides of the annular portion 631b of the convex edge 63b in the width direction of the atomizer 100; or along the width of the atomizer 100, the liquid channel bypasses or spans the annular portion 631b of the ledge 63 b.

And, a plurality or a plurality of spoiler structures 64b are arranged between the flange 63b and the peripheral sidewall 6220 b. And, the spoiler structure 64b is, for example, a protrusion or a barrier structure or the like located between the flange 63b and the peripheral sidewall 6220 b. Specifically, portions of the spoiler structure 64b abut or are bonded to the peripheral sidewall 6220b, and portions of the spoiler structure 64b abut or are bonded to the ledge 63 b; and the spoiler structures 64b are staggered between the ledge 63b and the peripheral sidewall 6220 b; further, when the liquid matrix flows in the liquid channel, the flow path of the liquid matrix is made to be roundabout or bent by the turbulence structures 64b, for example, as shown by R1 in fig. 14.

And, after assembly, the portion 32b of the capillary element 30b abuts against the surface 520b of the spacer element 50b and covers or conceals the port of the first liquid guiding aperture 52b at the surface 520b, thereby receiving or sucking up the liquid matrix.

Or in yet other variations, the turbulence structures 64b may also be depressions or protrusions disposed on the surface defining the liquid channel; the recess depth of the recess or the protrusion height of the protrusion may be about 0.3-2.0 mm.

In the above implementation, the arrangement of the turbulence structures 64b is advantageous to promote flow resistance during transfer of the liquid matrix, thereby providing uniform or smooth transfer of the liquid matrix through the liquid channels to the portions 32b of the capillary elements 30 b.

And in some implementations, the spacer element 50b is staked to the inner surface of the peripheral sidewall of the spacer element 60b so that the seal therebetween is maintained by interference. Or in yet other implementations, the seal is formed between the spacer element 50b and the inner surface of the peripheral sidewall of the spacer element 60b by a flexible sealing element.

Or in yet other variations, the surface of the top wall 6110b of the isolation element 60b facing the underside 620b is flat; and, the upper ledge 63b and/or the spoiler structure 64b are disposed on the surface 510b of the spacer element 50 b.

It should be noted that the description of the application and the accompanying drawings show preferred embodiments of the application, but are not limited to the embodiments described in the description, and further, that modifications or variations can be made by a person skilled in the art from the above description, and all such modifications and variations are intended to fall within the scope of the appended claims.
