Ceramic composite electronic cigarette heating pipe and electronic cigarette atomizing core employing same

Abstract

The invention discloses a ceramic composite electronic cigarette heating pipe which comprises an electric heating wire and a micro-porous ceramic pipe; a main body part of the electric heating wire is pre-embedded in the pipe wall of the micro-porous ceramic pipe; the electric heating wire is led out of the outside of the micro-porous ceramic pipe through connecting pins. A compact connecting piece is arranged at each of the upper and lower ends of the micro-porous ceramic pipe. The two connecting pins of the electric heating wire are lead out from the lower end of the micro-porous ceramic pipe; the compact connecting piece at the lower end is a metal connecting ring; a connecting pile protruding into the pipe wall of the micro-porous ceramic pipe is arranged on the upper side of the metal connecting ring. A double-electrode conductive connecting ring consists of an inner ring electrode and an outer ring electrode and is arranged on the lower side of the metal connecting ring; the outer ring electrode is electrically connected or integrally formed with the metal connecting ring; an insulating ring is arranged between the outer ring electrode and the inner ring electrode. The inner ring electrode and the outer ring electrode of the double-electrode connecting ring are respectively electrically connected with the two connecting pins of the electrical heating wire. When the heating pipe disclosed by the invention is in use, the double-electrode conductive connecting ring and a double-electrode conductive connecting column of an atomizing core are designed to be in threaded connection for realization.

Description

technical field [0001] The invention relates to a product component in the field of daily life, in particular to a heating component used in an electronic cigarette vaporizer, which is a ceramic composite electronic cigarette heating tube. [0002] The present invention also relates to an electronic cigarette heating core using the electronic cigarette heating tube. Background technique [0003] The current electronic cigarette products on the market heat a liquid e-liquid through a resistance wire, atomize the e-liquid, and inhale the vapor of the e-cigarette. [0004] The known atomization device of the electronic cigarette is made into an atomization chamber, and an atomization core is arranged in the atomization chamber. Such as Figure 4 As shown, it is an atomizing core with a known structure. The atomizing core is composed of a cylindrical shell and a resistance wire 101 inside. The liquid cotton 102 communicates with an external liquid storage chamber through the l...

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

The combined structure of the resistance wire and the liquid-conducting cotton makes it difficult to remove and replace the atomizing core.

[0007] Second, due to the penetration of the liquid-conducting cotton, the electronic cigarette liquid in the liquid-conducting cotton is in a saturated state when it is not inhaled. It may ooze, gather and drip, 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

[0008] 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

[0009] The most prominent defect is that when the heating wire of this structure is used in the electronic cigarette, it must cooperate with the liquid-conducting cotton to realize the functions of introducing liquid, heating the liquid, and atomizing the liquid. Therefore, the above-mentioned defects are the liquid-conducting cotton itself insurmountable defect
