Description

Atomizer and electronic atomization device

Technical Field

The embodiment of the application relates to the technical field of electronic atomization devices, 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 compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning the material. For example, the material may be tobacco or other non-tobacco products, which may or may not include nicotine. As another example, there are aerosol-providing articles, e.g. so-called electronic nebulizing devices. These devices typically contain a vaporizable liquid that is heated to vaporize it, thereby generating an inhalable aerosol. Known electronic atomisation devices comprise a liquid-conducting element which, in use, draws the liquid substrate from a portion of the liquid-conducting element and then delivers it to a portion associated with a heating element for heated atomisation. In the above electronic atomizing device, the liquid guiding member excessively or excessively rapidly transfers the liquid substrate to the heating element bonding portion, thereby forming frying oil during the heating process.

In particular to hard artificial cotton with Shore hardness of 20-70A. In alternative implementations, first liquid conducting element 50 is a rigid rayon comprising oriented polyester fibers, or a rigid rayon or rayon foam made of filamentary polyurethane, or the like. The first liquid guiding element 50 has a hardness or flexibility between that of a common flexible plant cotton/non-woven fabric (shore hardness is less than 20A) and that of a rigid porous ceramic/microporous metal (shore hardness is greater than 80A), so that the structure is stable and has extremely low expansion after absorbing and infiltrating a liquid matrix, and after assembly, the first liquid guiding element 50 is in contact with the inner wall of the outer shell 10/the pipe wall of the smoke output pipe 11 between a flexible contact and a rigid contact, so that on one hand, the liquid storage cavity 12 can be independently sealed by utilizing the flexibility of the first liquid guiding element, and on the other hand, the first liquid guiding element has a certain hardness and can be easily fixed and maintained. In particular, and as shown in the above figures, the first drainage element 50 is shaped to substantially fit the opening at the lower end of the reservoir 12 and may thus be used to cover, seal and seal the reservoir 12.

First fluid directing element 50 is fabricated from oriented fibers, such as polyethylene and/or polypropylene, that are substantially aligned in a lengthwise orientation, for example, a microtopography of polypropylene fibers having an alignment in one embodiment is shown in fig. 9. the alignment of the oriented fibers along the lengthwise direction of first fluid directing element 50 results in a stronger buckling resistance and thus a stiffer behavior of first fluid directing element 50. And the first liquid guiding element 50 prepared by adopting the organic fibers can keep enough gaps among fiber materials in the preparation process, so that the liquid matrix can be transferred, and the first liquid guiding element 50 has proper flexibility. The first liquid guiding member 50 having the above-oriented fibers is anisotropic. On one hand, the bending strength at least along the length direction is larger than that along the width direction; or on the other hand, has a drainage rate in the length direction that is greater than the drainage rate in the width direction.

The spacing is further controlled to be less than 2mm, thereby forming capillary channels for capillary action therebetween. The condensate falling or flowing to the air inlet end in the flue gas output pipe 11a is absorbed and guided to the atomizing chamber of the outer support 70a by the capillary force of the capillary channel, so that the condensate is prevented from being accumulated in the flue gas output pipe 11a to form a liquid column, and the problem of pumping the condensate is relieved or eliminated.
