A kind of low temperature tobacco smoking set heated by thermal current
Technical field
Smoking set technical field of structures the present invention relates to be used to suck incombustible low temperature tobacco.
Background technology
Correlative study shows conventional cigarette burning temperature more than 800 degrees Celsius, and cigarette is produced during burning
More than 5000 kinds of chemical substance, wherein carcinogenic chemicals just have a kind more than 80, the harm phase of the smog of generation to non-smokers
When big.With a series of release of low temperature not burning heater, the new tobacco that can effectively reduce harmful substance generation is occurred in that
Mode of heating, the harmful substance produced by this low-temperature heat mode than being subtracted significantly by the harmful substance produced by burning cigarette
It is few, the harm to body can be reduced again while consumer demand is met.
Burning type heating utensil is not to conduct heat by electrical heating elements for the low-temperature heat of current main flow, directly to being contacted
Tobacco product material heated, heating element heater is in blade-like, bar-shaped, cup-shaped etc., and this structure can cause tobacco product material
Material occurs being charred phenomenon near thermal source during heating partially due to being heated excessively and easily, and away from the cigarette of heat source side
Straw-made articles material causes fragrance and active ingredient burst size not enough because heating is insufficient again.The uneven heating knot of this heating
Structure, on the one hand causing tobacco-containing material cannot be fully utilized, and situations such as fragrance is not enough, amount of smoke is smaller occur, reduce user
Suction experience sense;On the other hand due to the superheated to contact layer tobacco product material, it is possible to cause to be produced in flue gas
More harmful substances.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, the present invention provides a kind of using the low temperature tobacco smoke heated by thermal current
Tool, to improve the uniformity of tobacco-containing material heating, promotes fragrance component uniform and fully discharges, and improves suction experience sense, and keep away
Exempt from tobacco-containing material to occur being charred phenomenon, reduce the generation of harmful substance.
The technical scheme that the present invention takes is as follows:

Brief description of the drawings
Fig. 1 is a kind of structural representation of the invention.
Fig. 2 is another structural representation of the invention.
Specific embodiment
As shown in figure 1, smoking set of the present invention by base 1, the insulating base being installed on base 2, be plugged on insulating base
Sleeve pipe 3, the tubular heating element 4 that is fixed in insulating base, shell 5, suction nozzle 6 constitute.The concrete structure of smoking set is as follows:Smoking set
It is recessed that base 1, bottom including the first outer ring of band cushion cap 12 and the first upper circular central recess 11 is installed on the first circular central
Insulating base 2 of in the groove 11 and top with the second outer ring cushion cap 22 and the second upper circular central recess 21, it is set with and sits vertically
Fall within the vertical tubulose heating that the sleeve pipe 3, bottom on the second outer ring cushion cap 22 is installed in the second upper circular central recess 21
Element 4, it is set with and is seated the shell 5 with top board on the first outer ring cushion cap 12 vertically, the top center of top board is machined with circle
Shape sinks platform 53, and cushion cap center offers through hole, and top board bottom carries the collar flange 52 for being plugged in the inwall of sleeve pipe 3, heavy in circle
The suction nozzle 6 of center band air guide channel 62 is fitted with platform 53, the bottom centre of suction nozzle is machined with and can insert cylindrical tobacco material 7
Jack;The positive pole 41 and negative pole 42 of heating element heater 4 are each passed through insulating base and are connected with electric supply installation;It is the in heating element heater 4
One cavity 8, forms the second cavity 9 between heating element heater 4 and sleeve pipe 3, the 3rd cavity 10 is formed between sleeve pipe 3 and shell 5, outside
Air admission hole 51 is offered in shell cylindrical wall, gas port 31 is offered in the bottom of sleeve pipe 3, as shown by the arrows in Figure 1, air is through shell
On air admission hole 51 enter the 3rd cavity 10, then enter the second cavity 9 through the gas port 31 on sleeve pipe, by the 3rd cavity, the
Air after two cavitys preheating is heated by the first cavity 8 again, is entered from the bottom of cylindrical tobacco material 7, to cylinder
Tobacco-containing material is uniformly heated, and the thermal current with tobacco component of generation is inhaled by the air guide channel 62 on suction nozzle for people
Food.The air admission hole 51 opened up on shell cylindrical wall top is two or more;The gas port 31 opened up in the bottom of sleeve pipe 3 is also two
More than.The tubular heating element 4 is ceramic heat cup or PTC or METAL HEATING PROCESS ring, or other heating element heaters.
The first upper circular central recess 11 on base of the present invention 1 is used for fixed insulation seat 2.On insulating base 2 second
Upper circular central recess 21 is used to fix tubular heating element 4.Described sleeve pipe 3 is hollow thin wall casing, the top of sleeve pipe
Collar flange 52 with the top board bottom of shell 5 is fitted close, to ensure the sealing property of smoking set.Tubular heating element 4 is fixed on
In second upper circular central recess 21 of insulating base, and tubular heating element not with casing-contact, also do not contacted with shell.Set
Pipe is highly higher than the height of tubular heating element.Sleeve pipe is located between shell and tubular heating element, by shell and tubular element
Between cavity be divided into the second cavity 9 and the 3rd cavity 10.Behind the circle of the insertion housing top end of suction nozzle 6 heavy platform 53, cylinder
Shape tobacco-containing material 7 is just suspended on the center of tubular heating element, and does not contact with tubular heating element.Air inlet on shell
Hole, the 3rd cavity, the gas port on sleeve pipe, the second cavity, the first cavity, the air guide channel on suction nozzle are turned on extraneous.Air
Enter the 3rd cavity through air admission hole, the air in the 3rd cavity is entered back into in the second cavity through gas port, then by the 3rd
Air after cavity, the second cavity preheating enters into cylindrical cigarette by the first cavity from the bottom of cylindrical tobacco material again
Careless material center, is uniformly heated to tobacco-containing material.3rd cavity, the second cavity, can simultaneously as air heat-insulation layer
Completely cut off most heat and transfer heat to shell.
The present invention is used first to air stepped heating, then by way of hot-air is heated to tobacco-containing material, heating
Uniform and abundant, 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, the experience of user
Effect is good.Due to using incombustible air mode of heating, tobacco-containing material can be avoided from occurring being charred phenomenon, be effectively reduced harmful
The generation of material, can be reduced to body harm again while consumer demand is met.Present invention reliability rational in infrastructure, each
Parts machining is simple, and assembling is easy, it is possible to decrease product cost.
Smoking set of the present invention is also variable to turn to structure as shown in Figure 2, by removing sleeve pipe 3, only produces two cavitys,
The first cavity 8 is formd between tubular heating element inwall and cylindrical tobacco material, in tubular heating element outer wall and shell
The second cavity 9 is formd between wall, air first enters the second cavity through air admission hole, by the air after the second cavity preheating again
Cylindrical tobacco material center is entered into from the bottom of cylindrical tobacco material by the first cavity, tobacco-containing material is carried out uniformly
Heating.Second cavity can completely cut off most heat and transfer heat to shell simultaneously as air heat-insulation layer.The change of the structure
Change can also equally play the beneficial effect of structure of the present invention, and within the protection domain of structure of the present invention.
