Problems solved by technology

[0003] At present, the heating temperature of heat-not-burn electronic cigarette products on the market is generally 300-350°C, and the heating material adopts alloy resistance wire or metal sheet, which has the following disadvantages: the service life is short, and the alloy resistance wire is prone to oxidation at high temperatures. It leads to a reduction in heating efficiency or even a blowout; poor thermal shock resistance, unable to withstand repeated and rapid power on and off operations for a long time

Embodiment 1

[0025] This embodiment relates to a nano-carbon fiber membrane rapid heating electronic cigarette heating tube, such as Figure 1-3 As shown, it includes: a hollow tube 10 , an electric heating layer 20 , an insulating and heat insulating layer 30 , an infrared reflection layer and a fixing layer 50 .

[0026] Specifically, the hollow tube 10 is used to accommodate tobacco leaves or cartridges. The electric heating layer 20 is coated on the outer wall of the hollow tube 10 and is electrically connected to the external circuit board for heating the tobacco leaves or cartridges placed in the hollow tube 10 . The insulation and heat insulation layer 30 covers the outer sidewall of the electric heating layer 20 . The insulating and heat insulating layer 30 is coated on the surface of the electric heating layer 20 to reduce the heat diffusion loss, enhance the heating effect of the hollow heating chamber, and reduce the temperature of the outer packaging to prevent hot hands. The...

Embodiment 2

[0032] Implementation example 2: the main difference between this embodiment and embodiment 1 is:

[0033] The graphitization treatment temperature of the carbon nanofiber film in the present invention is 2000° C., and the time is 2 hours, and the remaining conditions are the same as those in Example 1.

[0034]The nano-carbon fiber film prepared in this implementation example rapidly heats up the electronic cigarette heating tube. Under the voltage of 5V, the current is 1.6A, the temperature rises to 360°C within 3 seconds and maintains stable heat generation. After 4 hours of continuous power-on work, its resistance gradually increases to 5Ω. , the working temperature is gradually reduced to 290-310°C.

Embodiment 3

[0035] Implementation example 3: the main difference between this embodiment and embodiment 1 is:

[0036] The graphitization treatment temperature of the carbon nanofiber film in the present invention is 2800° C., and the time is 2 hours, and other conditions are the same as those in Example 1.

[0037] The nano-carbon fiber film prepared in this implementation example rapidly heats up the electronic cigarette heating tube. Under the voltage of 5V, the current is 2.1A, and the temperature rises to 400°C within 3 seconds and maintains stable heat. It works continuously for 1000h, and its resistance is 2.4Ω. Obviously, the working temperature is stable at 395-400°C.

Abstract

The invention discloses a rapid heating electronic cigarette heating tube with a carbon nanofiber membrane, and particularly relates to the technical field of electric heating devices. The heating tube comprises: a hollow tube; an electric heating layer which wraps the outer side wall of the hollow tube, is electrically connected with an external circuit board and is used for electrifying and heating tobacco leaves or smoke cartridges placed in the hollow tube; an insulating and heat-insulating layer which wraps the outer side wall of the electric heating layer; an infrared reflecting layer which wraps the insulating and heat-insulating layer; and a fixing layer which coats the outer side wall of the infrared reflecting layer. The hollow tube is used for containing the tobacco leaves or smoke cartridges, and the electric heating layer is the carbon nanofiber membrane. By adopting the technical scheme, the surface of the hollow tube is directly coated with the electric heating film, socompared with a traditional resistance wire heating tube, the heating tube of the invention has the advantages that the structure is simplified, the manufacturing process is simplified, the temperature rising speed is higher, the heating area is larger, heating is more uniform, the heating tube is a novel electronic cigarette heating tube. and better use experience can be brought to an electroniccigarette user while the harm is healthily reduced.

Description

technical field [0001] The invention relates to the technical field of electric heating devices, in particular to a nano-carbon fiber film heating tube for rapid heating of electronic cigarettes. Background technique [0002] With people's increasing concern for health and the pursuit of a green living environment, global tobacco control has become an obvious trend, but tobacco, as a special commodity, will not disappear from the market in a short time, so tobacco product harm reduction has become an important trend in the tobacco industry The inevitable trend of development, in which heat-not-burn is the most important solution, that is, do not light cigarettes, but use an external heat source of appropriate temperature to heat the tobacco leaves just enough to emit fragrance. This method can avoid carbon monoxide when traditional cigarettes are burned. Compared with the production of harmful substances such as tar, compared with atomized electronic cigarettes, it can resto...
