Atomizing core and smoke cartridge

Abstract

An atomizing core comprises a shell provided with a vertically-through containing cavity, a porous body wrapped in the containing cavity of the shell and a heating element arranged on the bottom face of the porous body, the porous body comprises a first surface making contact with atomized liquid and a second surface opposite to the first surface, the first surface is a liquid absorbing surface, the second surface is an atomizing surface, the heating element is arranged on the atomizing surface, the atomized liquid permeates to the atomizing surface from the liquid absorbing surface, the heating element on the atomizing surface is used for heating, and heat is conducted into the porous body to atomize the atomized liquid. The invention further discloses a smoke cartridge.

Description

technical field [0001] The present application relates to the field of electronic cigarettes, in particular to an atomizing core and a cartridge. Background technique [0002] The key component of the e-liquid atomized electronic cigarette is the atomizer. The atomizer needs an atomizing core that penetrates the e-liquid. The atomizing core is originally made of organic cotton, but organic cotton is prone to burning problems and odors And affect the use. In order to solve the above technical problems, a technical solution of using ceramic porous body as the atomizing core has appeared in the industry. The ceramic atomizing core will not cause the problem of burning, and the filtration performance is more stable than that of the cotton core. For example, the pod disclosed in patent CN211020987U uses a ceramic atomizing core. The ceramic atomizing core is generally divided into a liquid-absorbing surface and an atomizing surface. There are also some disadvantages. First, the...

Problems solved by technology

For example, the pod disclosed in patent CN211020987U uses a ceramic atomizing core. The ceramic atomizing core is generally divided into a liquid-absorbing surface and an atomizing surface. There are also some disadvantages. First, the porous ceramics are relatively brittle and easily broken, requiring thicker strength support, and the heating wire is printed on the bottom surface of the porous ceramics. The porous ceramics bear the supporting force and are easily broken, resulting in The heating wire is broken to form an open circuit, which affects the atomization of e-liquid; secondly, porous ceramics are generally fired with clay. After the e-liquid is atomized through the porous ceramic, it is easy to carry a muddy smell, and the reduction degree of e-liquid is not as good as that of cotton wicks.

[0003] At the same time, there has always been a technical problem in pod products that is difficult to solve, that is, the problem of oil leakage. Generally, the atomizing core uses a porous ceramic substrate as a liquid seepage device. The atomized liquid penetrates through the porous ceramic substrate. Atomized liquid atomized into smoke

The outside of the porous ceramic matrix needs to be wrapped with sealing silica gel and other materials to prevent oil leakage, but oil leakage still exists in actual use, and a balance air channel connecting the liquid storage chamber needs to be opened to ensure the air pressure balance in the liquid storage chamber

However, the porous ceramic matrix is ​​easily deformed during use, and there are micropores connected on the outer periphery, resulting in poor sealing and serious oil leakage.
