Description
Technical Field
The utility model relates to an electron cigarette technical field especially relates to an electron cigarette is preheating device for heater in electron cigarette technical field.
Background
Articles such as cigarettes, cigars and the like burn tobacco during use to produce tobacco smoke. The smoke generated by the combustion of tobacco contains a plurality of carcinogenic substances, such as tar, and the substances can cause great harm to human bodies after being inhaled for a long time. With the technological progress and the pursuit of people for healthy life, a cigarette substitute, namely an electronic cigarette, appears. One of the typical e-cigarette solutions has attempted to provide an alternative to these types of articles by creating products that release compounds without burning. Examples of such products are so-called heat non-combustible products, also known as tobacco heating products or tobacco heating devices, which release compounds by heating but not burning the material. The material may be, for example, tobacco or other non-tobacco products or combinations, such as blends, which may or may not contain nicotine. Similarly, there are also so-called smoke electronic smoking devices, which typically vaporize a liquid that may or may not contain nicotine.
At present, the heating non-combustion electronic cigarette products on the market mainly have three types:
one is ceramic heating sheet (advantage, rapid heating speed, large heat transfer area, uniform heating and good taste.)
The zirconia ceramic substrate and the noble metal heating slurry have small volume and light weight, can obtain high power density and high thermal efficiency; the temperature-rising type heat-insulation material has excellent thermal characteristics, is high in temperature-rising speed, and can obtain any temperature distribution; the reliability is high, the service life is long, the heating element material cannot be oxidized, and the acid and alkali resistance is excellent; corrosion resistance, high temperature resistance, uniform temperature, good heat conductivity and high heat compensation speed. There are also alternative products on the market today, which are much less costly than before.
The alumina ceramic and the heating slurry replace a new form of a heating sheet. The heating efficiency can be compared with that of the heating sheet.
Whether the heating sheet or the heating needle is adopted, one problem of central heating is that the temperature difference from the top to the bottom of the uneven temperature distribution of the whole heating body reaches about 100 ℃, so that the tobacco is not sufficiently baked and even has scorched flavor, and the tobacco waste is large. Special smoke cartridges are required to be matched with the sheet heating body to achieve the effect.
Two, the cylinder heating rod
The rod-shaped structure has high strength and cannot be broken. The high-temperature co-fired ceramic heating element has good compactness, and the heating wire is completely wrapped in the ceramic. The reliability is high after long-term use. The temperature rise speed is high, and the uniformity is good. The welding spot adopts 1000 ℃ silver brazing process, is stable and can resist 350 ℃ high temperature for a long time.
Thirdly, ceramic heating cup \ heating tube \ heating pan (advantages, rapid heating, high reliability and long service life)
The heating cup/heating tube/heating pot is a typical representative of the surrounding heating. Annular sectional heating, and accurate temperature control. The biggest problem of this method is that the heat utilization rate is low, one part of the heat is absorbed by the tobacco, and the other part of the heat is dissipated in the form of heat, and if the heat insulation is not good, the smoking set can scald hands.
No matter which kind of heating type's electron cigarette, it is through heat transfer mode heat transfer and exchange, is difficult to avoid the loss of heat, and to guarantee that smoking article is in suitable stoving temperature all the time, the work that the heating part need not be stopped all the time. The purpose of the preheat function is to more quickly bring the smoking article to a baking temperature, facilitating smoking of the smoking article to be smoother, because of the unreasonable structure in existing designs, the heat conductivity of materials is common and the heater is usually preheated, thereby enabling faster baking of the smoking article when actually smoking.
