Abstract

The invention discloses a heating assembly for an electronic cigarette and a preparation process of a heating tube of the heating assembly, and mainly relates to the technical field of electronic cigarettes. The heating assembly for the electronic cigarette consists of the heating tube and an electrode. The heating tube consists of a tubular body and a heating layer; the tubular body has the performance of transferring heat outside the tubular body to the inside of the tubular body and is used for accommodating an electronic cigarette bomb and carrying the heating layer; the heating layer is aconductive coating which is formed by printing conductive paste on the outer surface of the tubular body and generates heat after being electrified; the electrode is an annular electrode which is matched with the outer diameter of the tubular body, sleeved with the two ends of the tubular body and electrically connected with the heating layer. The heating assembly of the electronic cigarette hasthe advantages of high stability, excellent aging resistance, uniform heating performance, low manufacturing cost, simple structure and small size, and the size of the electronic cigarette can be obviously reduced.

Description

technical field

[0001] The invention relates to the technical field of electronic cigarettes, in particular to a preparation process of a heating component of an electronic cigarette and a heating tube thereof. Background technique

[0002] E-cigarettes are electronic products that mimic cigarettes. Traditional e-cigarettes use liquid e-liquid or solid-liquid mixed e-liquid, because the taste of liquid e-liquid is not pure enough compared to shredded tobacco, and there is leakage of e-liquid, it is inconvenient and unhygienic to replace and add e-liquid question. As a result, electronic cigarettes using solid cartridges that smoke shredded tobacco or health-preserving medicinal materials in a heat-not-burn manner have emerged. The characteristics of this electronic cigarette are more pure in taste, easy to use, and less harmful. However, the heating type of the existing electronic cigarettes that use liquid cartridges is generally rod-shaped, and its shape is not suitable ...

Examples

Embodiment 1

[0048] The heating component for electronic cigarettes using solid cartridges is composed of a heating tube and an electrode ring 3, wherein the heating tube is composed of a quartz glass tube 1 and a heating layer 2 printed with conductive paste on the outer surface of the quartz glass tube, and the quartz glass The tube 1 can transfer the heat generated by the heating layer to its interior to heat the electronic cigarette bomb placed inside the quartz glass tube 1; the inner diameter of the electrode ring 3 matches the outer diameter of the quartz glass tube 1 and is set on the quartz glass Both ends of the tube 1 are electrically connected to the heating layer 2 . The above is a description of the specific structure of the heating element of the present invention. The present invention adopts external heating and internal heating during use. This heating method can make the electronic cigarette bomb heated evenly, the smoke taste is pure, and the service life of the cartridg...

Embodiment 2

[0057] The structure of its heating element is as in the first embodiment.

[0058] The following is aimed at the problem of uneven layout of the sintered coating on the quartz glass tube when the electronic paste is printed in this industry. The present invention proposes a screen printing process for printing the conductive paste on the tubular body. The process includes the following steps :

[0059] Step 1. Selection of stencil: This process selects a polyester mesh with a mesh number of 270 mesh, an aluminum mesh frame, a mesh stretching angle of 20 degrees, a mesh tension of 25N, a film thickness of 20μm, and a mesh with a graphic-to-text frame ratio of 25. Plate, put the screen into the screen printing machine;

[0060] Step 2. Fix the substrate, choose a ceramic tube as the substrate, and adjust the distance between the substrate and the screen to control the distance at 1.7 mm;

[0061] Step 3. Select a flat scraper with a Shore hardness of 70, and adjust the angle ...

Embodiment 3

[0065] Embodiment 3: The structure of the heating element is as in Embodiment 1.

[0066] The following is aimed at the problem of uneven layout of the sintered coating on the quartz glass tube when the electronic paste is printed in this industry. The present invention proposes a screen printing process for printing the conductive paste on the tubular body. The process includes the following steps :

[0067] Step 1. Selection of stencil: This process uses stainless steel wire mesh with a mesh number of 380mesh, a steel mesh frame, a mesh stretching angle of 30 degrees, a mesh tension of 30N, a film thickness of 50μm, and a graphic-text frame ratio of 30%. Stencil, put the stencil into the screen printing machine;

[0068] Step 2. Fix the substrate, choose a quartz tube as the substrate, and adjust the distance between the substrate and the screen gap to control the distance at 1.5 mm;

[0069] Step 3. Select a pointed scraper with a Shore hardness of 80, and adjust the angl...
