Abstract
The present invention provides a kind of cellular alumina ceramic heating elements and preparation method thereof, including cellular alumina ceramics, fever printed circuit, conducting wire；The fever printed circuit is circumferentially positioned at the outer surface of cellular alumina ceramics；The first and last end of the fever printed circuit is provided with conducting wire.Cellular alumina ceramic heating element of the invention has good heating efficiency, and thermal conductivity is high, and compactness is good, can quickly heat air, energy saving, while will not adsorb flue gas particle, free from extraneous odour.
Description
Technical field
The present invention relates to a kind of cellular alumina ceramics of electronic cigarette technical field more particularly to electronic cigarette technical field hairs
Hot body and preparation method thereof.
Background technique
The product of cigarette, cigar etc. during use burning tobacco to generate tobacco smoke.The smog of result of combustion of tobacco
In contain many carcinogens, such as tar, very big harm can be generated to human body by sucking these substances for a long time.With science and technology into
There is a kind of cigarette substitute i.e. electronic cigarette in step and pursuit of the people to healthy living.One of typical electronic cigarette side
Case has attempted to the product by generating the release compound in incombustible situation to provide the substitution of the product of these types
Object.The example of this product is so-called heating not combustion products, also referred to as tobacco heating product or tobacco heating mechanism, is led to
It crosses and heats but do not burn the material to discharge compound.The material can be such as tobacco or other non-tobacco products or combination,
Such as mixture can contain or not contain nicotine.Similarly, there is also so-called tobacco tar electronic cigarette devices, usually
Make the liquid vaporization that may or may not contain nicotine.
It is heated there are mainly three types of not burning type electronics smoke products on the market at present:
One: (advantage, heating rate is fast, and heat transfer area is big, and homogeneous heating is in good taste for ceramic heating plate.)
Zirconia ceramics substrate+noble metal heat generating pastes, it is small in size, it is light-weight, high power density, the thermal efficiency can be obtained
It is high；There are excellent thermal characteristics, heating rate is fast, can obtain arbitrary Temperature Distribution；High reliablity, long-life, heater material
Material will not aoxidize, and acid-proof alkaline is excellent；Corrosion-resistant, high temperature resistant, temperature is uniform, good heat conductivity, and thermal compensation speed is fast.At present
Also there is the product of substituted type on the market, cost is much lower than before.
Aluminium oxide ceramics+heat generating pastes substitutes the new form of one kind of fever tablet.Heating efficiency can be with fever tablet phase
Than.
Either fever tablet is still generated heat needle, and a problem of center fever is entire heater temperature distribution is non-uniform top
The temperature difference of portion to bottom reaches 100 degrees centigrades, causes tobacco roasting insufficient or even has the smell of burning, and tobacco waste is big.It needs
The smoke grenade and the cooperation of sheet calandria for wanting speciality can be only achieved effect.
Two: cylindrical body heating bar
Club shaped structure, intensity is high, will not be broken off.High-temperature co-fired ceramics heater, compactness is good, and heating wire is wrapped completely
It is rolled in ceramics.High reliablity is used for a long time.Heating rate is fast, and uniformity is good.Solder joint uses 1000 DEG C of silver brazing techniques, solder joint
Stablize, is resistant to 350 DEG C of high temperature for a long time.
Three: ceramic heating cup heat-generating pipe heating boiler (advantage, fever is fast, high reliablity, and the service life is long)
Heating cup heat-generating pipe heating boiler be the Typical Representative around to generate heat.Looped sections heating, precise control of temperature.This
The problem of kind of mode maximum is that heat utilization ratio is low, and heat a part is given out by the form that tobacco absorbs another part heat
Go, if it is heat-insulated do it is bad if, smoking set can scald one's hand.
The entitled a kind of heating air type electronic cigarette heater that domestic applications number are CN201721741519.0 is a kind of
The electronic cigarette of typical non-contact thermal, specifically discloses following content: including the thermal sleeve with casing hollow space,
The first heating tube is provided in the casing hollow space of the thermal sleeve, first heating tube has absolutely empty in heating tube
Between, the sealed bottom of first heating tube is equipped with the second heating tube in the heating tube hollow space of the first heating tube, described
There is inside second heating tube intermediate heating space, have the between the thermal sleeve inner sidewall and the first heating tube lateral wall
One heating space, has the second heating space between the first heating tube inner sidewall and the second heating tube lateral wall, and described the
It is provided with the first flow spiral pipe in one heating space, the second flow spiral pipe is provided in second heating space, it is described
The first air-flow notch for being connected to the first heating space Yu the second heating space is provided in first heating tube, described second adds
The second air-flow notch for being connected to the second heating space and intermediate heating space, the thermal sleeve top are provided on heat pipe
It is provided with tobacco container, the tobacco container has tobacco accommodating chamber, and the tobacco accommodating chamber and the internal heating space connect
It is logical.Its mode for heating air is heated by using the form of double-layer heating pipe, and heating power is increased, and cooperates air-flow spiral shell
Coil is heated rapidly air when suction, makes to reach the air themperature on tobacco and reaches suitable standard.But in the program
Structure is complicated for the double-layer heating piece of use, can not be integrally formed, and assembling difficulty is larger, high production cost, heating sheet and air
Contact area it is limited, heating efficiency is general, to reach enough temperature and need to expend a large amount of electric energy, energy-saving and emission-reduction are not achieved
Effect.
Its contact heating baking technology as described above mainly carries out heat transfer and exchange by thermaltransmission mode, i.e.,
Temperature conduction is baked object (smokeable substance) by one heating conductor (such as ceramic heating plate or needle).Such heating method lacks
There are two point is main: 1, it is poor to be baked object (smokeable substance) heating conduction, cannot sufficiently transmit temperature, cause in roast body
Outer baking is uneven；2, it is big to be baked object space density difference for various types, when replacement different type is baked object,
Its heated baking effect is difficult to ensure.Generally have to there could be preferable effect using its matched roast, adaptability is very
Difference.In short, there are the technological deficiencies such as baking uneven, amount of smoke is small, mouthfeel is light, poor user experience in such heating device, it is described
Many disadvantages seriously limit this field and develop and promote and apply further along.
