Embodiment 1

[0026] Soak a nickel-chromium alloy (model Cr20Ni80) with a diameter of 0.1mm in a mixed solution of orthosilicon acetate: absolute ethanol: distilled water with a molar ratio of 1:15:9.5, and adjust the pH of the solution to 2.8. After stirring for 5 minutes at 100°C, take it out and dry it at 120°C for 1 hour, and finally burn it at 600°C for 2 hours under nitrogen atmosphere to obtain a composite heating wire with a silicon oxide film thickness of about 5 μm. The porosity of the film layer was measured to be 4.2% by weighing method (wetting liquid is electronic cigarette oil).

Embodiment 2

[0028] Place a nickel-chromium alloy (model Cr20Ni80) with a diameter of 0.1 mm in a vacuum of 2×10 -3 In the Pa chamber, keep the temperature at 200°C, and control the gas mass flow ratio of silane (purity 99.99%) / oxygen (purity 99.99%) / ammonia (purity 99.99%) / hydrogen (purity 99.99%) to 3:1: At 1:20, plasma vapor phase chemical deposition (PECVD) with a voltage of 1000V and a power of 2000W was used on the wire substrate for 100min to obtain a composite heating wire with a silicon nitride oxide film thickness of about 2.5μm. The porosity of the film layer was measured to be 1.4% by weighing method (wetting liquid is electronic cigarette oil).

Embodiment 3

[0030] Iron-chromium-aluminum (type 0Cr21Al6Nb) with a diameter of 0.2mm is immersed in a mixed solution of tetrabutyl orthotitanate: absolute ethanol: distilled water with a molar ratio of 2:14:9.5, and the pH value of the solution is adjusted to 7.8. After stirring for 8 minutes, take it out and dry it at 120°C for 1 hour, and finally burn it at 600°C for 2 hours under a nitrogen atmosphere to obtain a composite heating wire with a titanium dioxide film thickness of about 4 μm. The porosity of the film layer was measured to be 6.9% by weighing method (wetting liquid is electronic cigarette oil).

Abstract

The invention provides a composite heating wire for electronic cigarettes. The composite heating wire comprises a core part and a shell part arranged on the outer surface of the core part; the core part is a linear metal heating wire; the shell part comprises at least one inorganic film layer. According to the composite heating wire, the inorganic film layer with chemical inertness covers on a metal alloy heating surface, so that oil fume is prevented from directly contacting metal alloy, chemical reactions between the metal alloy heating wire with chemical activity and oil fume can be effectively prevented, and charring gas and electrothermal property influencing the heating wire can be avoided; furthermore, the heating wire is only a diameter performance surface, and the thickness of the inorganic film layer is reasonably controlled, so that the heating efficiency and flexibility of the composite heating wire can be guaranteed, and the composite heating wire is highly compatible with an existing electronic cigarette structure.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a composite heating wire for electronic cigarettes. Background technique [0002] Electronic cigarettes include an atomizing component for atomizing e-liquid and a battery component for power supply. The atomization assembly includes an oil storage element for oil storage and a heating element for heating e-liquid. Electronic cigarettes in the prior art usually generate smoke by heating and atomizing e-liquid with a low boiling point. This e-liquid often uses propylene glycol and glycerin as base materials, and adds nicotine and essence. At present, the common heating element is iron-chromium-aluminum alloy or nickel-chromium alloy, but the central temperature of the atomizer is above 280°C for a long time, which will cause chemical reaction between the chemically active metal alloy heating wire and the e-liquid, resulting in burnt The smelly gas will ...
