Ceramic composite electronic cigarette heater

Abstract

The invention discloses a ceramic composite electronic cigarette heater which comprises a heating component and a ceramic wrapping layer. The heating component is an electric heating component, a main body of the heating component is embedded in the ceramic wrapping layer, and the heating component is led outside the ceramic wrapping layer through wiring pins. The heater is a typical tubular heater, the heating component is embedded in the tubular middle segment main body portion, and the ceramic wrapping layer on the middle segment main body portion is a ceramic tube provided with internal micro holes. One or more ends of the heater are connected with dense connection pieces. The dense connection pieces can be metal connection pieces or ceramic connection pieces, and when the connection pieces are metal connection pieces, the connection pieces are arranged at the ends of the tubular heater and also serve as wiring pins of the heating component; the heater can also be a spiral heater, an electric heating wire wound in a spiral mode serves as the heating component, and the ceramic wrapping layer is a coated ceramic thin layer arranged on the surface of the electric heating wire in a wrapped mode. The heating component wrapped by ceramic can achieve functions of being insulating with other components, liquid guidance, high temperature resistance and the like.

Description

Technical field [0001] The invention relates to a product component in the field of daily life, in particular to a heating device used in an electronic cigarette atomizer, which is a ceramic composite electronic cigarette heater. Background technique [0002] At present, the electronic cigarette products on the market are equipped with an atomizing core, and an electric heating wire is arranged in the atomizing core, which heats a liquid e-cigarette liquid through the resistance wire, and the e-cigarette liquid is atomized and then the mist of the electronic cigarette is smoked. The electronic cigarette core of well-known structure such as Figure 7 As shown, the atomization core is composed of a cylindrical shell and a resistance wire 101 inside. The resistance wire 101 is wound into a spiral shape. The spiral body of the spiral resistance wire 101 is provided with a rope-shaped liquid guiding cotton 102. Through the liquid guiding cotton 102, Then, it communicates with an extern...

AI Technical Summary

Problems solved by technology

During the use of the atomizing core, due to the direct contact between the resistance wire 101 and the liquid-conducting cotton 102, the direct-contact part of the liquid-conducting cotton 102 is likely to be carbonized and coked during the heating process, and loses the role of penetrating liquid-conducting, affecting the performance of the liquid-conducting cotton 102. service life

At the same time, it is easy to contaminate the outside of the resistance wire 101 during the carbonization and coking process, which reduces the heat conduction capacity of the resistance wire 101 itself, and even causes the resistance wire 101 to harden and become brittle, which affects the service life of the resistance wire.

[0005] Second, due to the penetration of the liquid-conducting cotton 102, the electronic cigarette liquid in the liquid-conducting cotton 102 is in a saturated state when not inhaled. At this time, the liquid-conducting cotton 102 can not only introduce electronic cigarette liquid, The e-cigarette liquid may also drip from the seepage, and the dripped e-cigarette liquid will leak out from the air intake hole at the lower end of the atomizing core, causing leakage problems

[0006] The third is that when using a structure combining liquid-conducting cotton and heating wire, since the liquid-conducting cotton is a fibrous material and lacks the necessary rigidity, it must be installed manually during installation, and it is difficult to achieve large-scale automatic production

[0007] The most prominent defect is that when the heating wire of this structure is used in electronic cigarettes, it must cooperate with liquid-conducting cotton to realize the functions of introducing liquid, heating liquid, and atomizing liquid, so the above-mentioned defects are all liquid-conducting cotton inherent insurmountable defect
