A kind of heating of thermal current is not burnt smoking set
Technical field
The present invention relates to smoking set technical field of structures, the specially incombustible smoking set structure of low temperature.
Technical background
Correlative study shows conventional cigarette burning temperature at 800 degrees Celsius or more, and cigarette generates during burning
More than 5000 kinds of chemical substance, wherein carcinogenic chemicals just have more than 80 kinds, the harm phase of the smog of generation to non-smokers
When big.With a series of release of low temperature not burning heater, there is the new heating that can effectively reduce harmful substance generation
Mode, harmful substance ratio caused by this mode of heating are greatly reduced by harmful substance caused by burning cigarette, full
It can be reduced to body harm again while sufficient consumer demand.
Burning type heating utensil is not to conduct heat by electrical heating elements for the low-temperature heat of mainstream at present, directly to being contacted
Tobacco product material heated, heating element is in blade-like, rodlike, cup-shaped etc., and this structure can lead to tobacco product material
Material is during heating, close to heat source partially due to being heated excessive and easily occurring being charred phenomenon, and the cigarette far from heat source side
Straw-made articles material causes fragrance and active ingredient burst size insufficient because heating is insufficient again.This non-uniform fever knot of heating
On the one hand structure causes tobacco-containing material and is unable to fully utilize, situations such as fragrance is insufficient, amount of smoke is smaller occur, reduce user's
Aspirate experience sense;On the other hand due to the excessive heating to contact layer tobacco product material, it is possible to cause to generate more in flue gas
More harmful substances.
Invention content
In view of above-mentioned deficiencies of the prior art, the present invention provides a kind of smoking set that do not burn heated using thermal current, to carry
The uniformity of high tobacco-containing material heating, promotes fragrance component uniformly and fully discharges, and improves suction experience sense, and avoid tobacco material
Material occurs being charred phenomenon, reduces the generation of harmful substance.
The technical solution adopted by the present invention is as follows:
A kind of heating of thermal current is not burnt smoking set, and the smoking set includes pedestal, the central electrode that is installed in pedestal, is set
The insulation silica gel sheath that is placed between pedestal and central electrode, is installed on insulating base top at the insulating base being installed at the top of central electrode

The solid metal cylinder of disk, cylindrical portion are plugged in centre hole of base, and insulation silica gel sheath is by central electrode and pedestal phase
Isolation;The insulating base is the cylindrical tube that top offers the air inlet duct extended radially through with internal thread, lower part, and insulate seating
It is identical as the internal diameter of insulating base cylindrical tube in the internal diameter that in the top plate of central electrode, is placed in the heating element on insulating base and
Top is higher than the wall of cup height of pedestal;The upper cover is top has bottom pipe, cylindrical parts to be downwardly into heating unit with cover rim
In part, tube bottom part is located in insulating base and with insulating base by the equipped connection of screw thread, and air admission hole is offered in tube bottom;It is described
Sleeve is placed on the stair-step of pedestal outermost level-one, and the upper and lower part of sleeve is matched with upper cover and pedestal by screw thread respectively
Load connects, and at least two air admission holes are offered on sleeve wall;One pole of heating element is by conducting wire along the top of insulating base
It is tightly linked with the outer wall of upper cover pipe, another pole is closely joined by conducting wire along insulating base outer wall bottom end and the top of central electrode
Knot;The inner cavity of upper cover is as materials chamber, for putting tobacco-containing material;The first chamber is formed between the wall of cup and sleeve of cup-shaped base
Body, forms the second cavity between wall of cup and insulating base and heating element, the bore section of insulating base forms third cavity, on sleeve
Air admission hole, the cavity between base top and upper cover cover rim bottom, the air inlet duct of insulating base, upper cover air admission hole by materials chamber
It is in communication with the outside, air enters the first cavity through the air admission hole on sleeve, and the air in the first cavity is entered back into the second cavity
After middle preheating, third cavity is entered by air inlet duct, finally the air admission hole Jing Guo upper cover enters materials chamber to tobacco-containing material
It is evenly heated.
The present invention using first to air heat, in such a way that hot-air heats tobacco-containing material, homogeneous heating and
Fully, it is possible to increase amount of smoke, the utilization rate of active components in tobacco is high, and the fragrance in flue gas is abundant, and the experience effect of user is good.
Due to using incombustible air mode of heating, avoidable tobacco-containing material to occur being charred phenomenon, it is effectively reduced harmful substance
It generates, can be reduced to body harm again while meeting consumer demand.Structure of the invention is rationally reliable, each parts
Processing is simple, and assembly is easy, can reduce product cost.

Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
Thermal current as shown in Figure 1 heats the smoking set that do not burn, by pedestal 6, the central electrode being installed in pedestal 4, setting
Insulation silica gel sheath 5 between pedestal and central electrode, is installed on insulating base top at the insulating base 3 being installed at the top of central electrode
Upper cover 2 that the tubular heating element 7 in portion, lower part are plugged in heating element, the cylinder-shaped sleeve 1 being set in outside upper cover and pedestal
Deng composition.
The pedestal is the flat cupuliform metal pedestal with footing 61, and footing and bottom of the cup carry centre bore, wall of cup part
Internal face be straight wall, outside wall surface be the bottom-up three-level ladder wall surface being retracted step by step;The central electrode 4 is band top plate 41
Solid metal cylinder, cylindrical portion is plugged in centre hole of base, and central electrode and pedestal are separated by by insulation silica gel sheath 5
From.The insulating base 3 is the cylindrical tube that top offers the air inlet duct 31 extended radially through with internal thread, lower part, insulating base
