Electronic atomization device and atomizer and heating body thereof

Abstract

The invention discloses an electronic atomization device and an atomizer and a heating body thereof. The heating body is used for heating and atomizing an aerosol generating substrate, the heating body comprises a substrate layer and a heating layer, the substrate layer comprises a first surface and a second surface opposite to the first surface, and the heating layer is formed on the first surface and / or the second surface. The heating body further comprises a plurality of through holes with capillary acting force, and the through holes are lengthwise and respectively penetrate from the firstsurface to the second surface. The substrate layer is matched with most of the through holes with capillary acting force, so that the porosity of the heating body can be accurately controlled, and the consistency of products is improved.

Description

technical field [0001] The invention relates to an atomizing device, in particular to an electronic atomizing device, an atomizer and a heating element thereof. Background technique [0002] Electronic atomization devices are generally used to simulate smoking articles or inhalers for the inhalation of medicaments for the treatment of respiratory diseases. The electronic atomization device includes an atomizer and a power supply, and the atomizer is provided with a heating element for atomizing an aerosol-generating substrate. [0003] The wick is an existing heating body, and the wick makes the liquid aerosol generating matrix to be atomized reach the heating wire through capillary action. Wicks are mostly made of fiberglass, and individual fiberglass snaps off easily, so there is a risk that the user will inhale loose or dislodged fiber fragments. [0004] Porous ceramic heating body is more and more popular in the market because of its high temperature stability and rel...

AI Technical Summary

Problems solved by technology

The heating power of the heating element is set in conjunction with the parameters of the ceramic body such as thermal conductivity, porosity, and permeability. However, in the mass production of porous ceramics, the range of porosity fluctuates relatively widely, and the heating power is difficult to accurately match, resulting in the same batch of products leaving the factory. The atomization effect of the electronic atomization device is not consistent

[0005] In addition, due to the poor liquid locking ability of porous ceramics, it is easy to leak oil

The surface roughness of porous ceramics is relatively large, and the thickness of the heating film is difficult to be uniform, resulting in local high temperature and dry burning
