Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomization devices, in particular to an atomization core component and an atomization device. Background Art
[0002] Electronic atomizers are also known as virtual cigarettes, e-cigarettes, steam cigarettes, etc. They have the same appearance as cigarettes and a similar taste to cigarettes. They are mainly used to simulate the feeling of smoking without affecting health, so as to help people quit smoking or replace cigarettes. The core component of an electronic atomizer is a heating component, which heats the atomized liquid inside the electronic atomizer to form smoke that can be inhaled; the common structure of a heating component includes a porous substrate and a heating element disposed on the porous substrate.
[0003] The existing porous matrix usually uses a ceramic material as a matrix combined with a metal heating element to form a ceramic core heating component. The columnar ceramic core heating element includes a ceramic matrix with a through hole in the center and a heating element arranged on the inner wall of the through hole. The heating element is vertically installed in the atomizing tube in the atomizer, and the bottom of the atomizing tube is the liquid inlet. When the atomized liquid enters the atomizing tube from the bottom and is then transmitted to the entire ceramic matrix through the oil-conducting cotton or the capillary force of the ceramic matrix, since the ceramic matrix is installed vertically, the atomized liquid on the ceramic matrix not only has a long transmission path, but also requires the gravity of the atomized liquid, which can easily cause the problem of untimely liquid supply at the top of the ceramic matrix, and dry burning can easily occur at the top of the ceramic core, which not only affects the suction experience and health, but also damages the atomizer device. The conventional solution is to increase the porosity of the ceramic matrix to enhance the capillary force, but this solution is prone to sacrifice the strength of the ceramic matrix, so it is also undesirable.
[0004] In addition, the heating element includes a first electrode portion and a second electrode portion. When the heating element and the ceramic substrate are manufactured as one piece, the heating element is mainly connected to the ceramic substrate through the first electrode portion and the second electrode portion, and the bonding surface is small. As a result, after the heating element and the ceramic substrate are co-fired, some positions of the heating element cannot be tightly combined with the ceramic substrate. The positions that are not tightly combined are also prone to dry burning due to insufficient oil supply, which brings a bad taste experience. Utility Model Content
