Atomizing and heating assembly for electronic cigarette

Abstract

The invention discloses an atomizing and heating assembly for an electronic cigarette and belongs to the technical field of electronic cigarettes. The atomizing and heating assembly comprises heating wires and a ceramic heating core. The heating core is in a double-circular-truncated-cone shape, and the heating wires are regularly wound on the outer surface of the heating core. The ceramic material of the ceramic heating core is porous ceramic or foamed ceramic, and is high in chemical stability and heat conductivity, and gas molecules can pass through the ceramic material. The middle of the ceramic heating core is of a hollow structure or a solid core structure, and the two outer ends of the ceramic heating core are of a hollow structure. The diameter of the middle of the ceramic heating core is 1-2 times of the wall thickness of the two outer ends of the ceramic heating core. The heating wires are regularly wound on the outer surface of the ceramic heating core. The atomizing and heating assembly has the advantages that the heating core is in the double-circular-truncated-cone shape, the cigarette liquid amount for oil guiding on the side close to the outer end is sufficient, along with oil guiding, the diameter of the heating core for oil guiding becomes smaller and smaller, and the needed cigarette liquid guiding amount of the middle of the heating core becomes smaller and smaller; the ceramic material used for the heating core is saved, the contact area of cigarette liquid and the ceramic material is increased, and the oil guiding speed is increased.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to an electronic smoke heating component. Background technique [0002] With the rise of new tobacco products in the world, major domestic tobacco companies and private enterprises have also actively responded and invested in the R&D and design of electronic cigarettes, actively promoting the industrialization and scale of electronic cigarettes, and the automation of product production. With the advancement of the company's R&D and design, new oil guide rope materials have been gradually discovered. At present, the main oil guide rope materials on the market are glass fiber, cotton, etc., but they also have certain inherent defects. Slag will be produced within a period of time, which is easy to enter the lungs of the human body with the airflow and is not easy to decompose, causing harm to the human body; the cotton oil guide rope has the characteristics o...

[0002] With the rise of new tobacco products in the world, major domestic tobacco companies and private enterprises have also actively responded and invested in the R&D and design of electronic cigarettes, actively promoting the industrialization and scale of electronic cigarettes, and the automation of product production. With the advancement of the company's R&D and design, new oil guide rope materials have been gradually discovered. At present, the main oil guide rope materials on the market are glass fiber, cotton, etc., but they also have certain inherent defects. Slag will be produced within a period of time, which is easy to enter the lungs of the human body with the airflow and is not easy to decompose, causing harm to the human body; the cotton oil guide rope has the characteristics of high oil conduction rate, but it cannot withstand heat. When dry burning occurs, the shrinkage rate will be reduced. High, leading to damage to the oil guide rope, the replacement rate is high, otherwise it is easy to cause low atomization temperature and bad taste

Therefore, it is urgent to find new oil-conducting materials, and ceramic heating cores are gradually discovered and recognized by people. However, such products currently on the market only occupy a small part of the market and have not yet reached large-scale application.

[0003] Most of the existing atomization products are cylindrical. During the atomization process of the heating wire, the e-liquid slowly flows from both ends to the middle, and a part of the e-liquid is slowly atomized during the flow process; when the smoking interval When the smoking time is short or the smoking time is long, the smoke oil has been atomized before it reaches the middle of the heating core, and the middle heating wire has no smoke oil and can be atomized to form dry burning; the heating wire may instantly heat up to 500 degrees or Higher, it will have a certain impact on the ceramic heating core, thereby affecting the taste of the electronic cigarette; if the liquid is sufficient, it may lead to insufficient atomization temperature, large atomized aerosol particles, resulting in insufficient taste
