Description

Alumina honeycomb ceramic heating body
Technical Field
The utility model relates to an electron cigarette technical field especially relates to an aluminium oxide honeycomb ceramic heat-generating body of 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 the method is that the heat utilization rate is low, one part of the heat is absorbed by tobacco and the other part of the heat is radiated in a heated mode, and if the heat insulation is not good, the smoking set can scald hands.
The domestic application number is CN201721741519.0, the name of which is a heated air type electronic cigarette heater, which is a typical non-contact heating electronic cigarette, and the following contents are specifically disclosed: the heat insulation device comprises a heat insulation sleeve with a sleeve hollow space, wherein a first heating pipe is arranged in the sleeve hollow space of the heat insulation sleeve, the first heating pipe is provided with a heating pipe hollow space, the bottom of the first heating pipe is sealed, a second heating pipe is arranged in the heating pipe hollow space of the first heating pipe, an intermediate heating space is arranged in the second heating pipe, a first heating space is arranged between the inner side wall of the heat insulation sleeve and the outer side wall of the first heating pipe, a second heating space is arranged between the inner side wall of the first heating pipe and the outer side wall of the second heating pipe, a first airflow spiral pipe is arranged in the first heating space, a second airflow spiral pipe is arranged in the second heating space, a first airflow notch for communicating the first heating space with the second heating space is arranged on the first heating pipe, and a second airflow notch for communicating the second heating space with the intermediate heating space is arranged on the second heating pipe, the upper part of the heat insulation sleeve is provided with a tobacco container, the tobacco container is provided with a tobacco containing cavity, and the tobacco containing cavity is communicated with the internal heating space. The mode of heating the air is that the air is heated by adopting a double-layer heating pipe, the heating power is increased, and the air is rapidly heated when being sucked by matching with the airflow spiral pipe, so that the temperature of the air on the tobacco reaches the proper standard. However, the double-layer heating sheet adopted in the scheme has a complex structure, cannot be integrally formed, is high in assembly difficulty and production cost, has a limited contact area between the heating sheet and air, is general in heating efficiency, consumes a large amount of electric energy when reaching a sufficient temperature, and cannot achieve the effects of energy conservation and emission reduction.
As mentioned above, the contact heating baking technology mainly transfers and exchanges heat by means of heat transfer, i.e. a heat conductor (such as a ceramic heat generating sheet or pin) transfers temperature to the object to be baked (smoking material). The disadvantages of this heating method are mainly two: 1. the baked objects (smoke substances) have poor heat conduction performance and cannot fully transfer temperature, so that the inside and outside baking of the baked objects is uneven; 2. the difference of the space density of various baked objects of different types is large, and the heating and baking effect is difficult to guarantee when the baked objects of different types are replaced. The good effect can be achieved only by using the matched baking object, and the adaptability is poor. In summary, such heating devices have technical defects of uneven baking, small smoke amount, light taste, poor user experience and the like, and the defects seriously limit further forward development and popularization and application in the field.
The honeycomb ceramic is mainly used in the adsorption treatment of automobile exhaust, the characteristics of porosity and large adsorption area of the honeycomb ceramic are utilized, harmful particles can be better adsorbed, and besides a pore canal with a special honeycomb shape, a ceramic body of the honeycomb ceramic also has micropores, so that the honeycomb ceramic has a strong adsorption effect. In electron cigarette heating field, need treat and toast the pipe tobacco and carry out quick heating, consequently need the heating member to have good heat conductivity, but general pottery has good heating efficiency, but the heat conductivity is not high, consequently need adopt contact heating mode just can play better stoving effect, for example the heater of traditional ceramic heating piece formula. The use of ceramics as the heating body in non-contact heaters is a highly unwieldy option in the prior art.
