The vertical view of the cigarette case that Fig. 3 opens.

Fig. 1 is the cross section side by side that passes cigarette holder 10, smoke 12 and adapter 14.

Totally make by known filtering material, as the filter tip of common cigarette for columniform cigarette holder 10.One end of cigarette holder 10 is configured with pump orifice 18, and the other end that deviates from pump orifice 18 of cigarette holder 10 is configured with the depressed part 20 of hollow cylinder.Except depressed part left end surperficial and shown in Figure 1, the surface 22 of cigarette holder 10 is configured to seal cellular.

Smoke 12 has columniform watchcase or main body 24, and it is made by heat-barrier material, for example adopts ceramic material, and this main body 24 comprises heat pipe 26 and adopts the good material of heat-conductive characteristic to make, for example copper.For outside the main body 24, and the profile of the exterior contour at outstanding position 28 and depressed part 20 is roughly corresponding according to the end nipple on heat pipe shown in Figure 1 26 left sides.The end face at outstanding position 28 is what open wide, and preferable configuration has break-through opening 30 in the cylindrical skirt at outstanding position.But also end face can be sealed, and then other at least one break-through opening of structure.

Right-hand end in main body 24 is configured with depressed part 32, and the end on heat pipe 26 the right is arranged in depressed part 32 then openly.

The end on main body 24 the right has formed an air-flow inlet port with the opening of heat pipe 26, and this air-flow inlet port is connected with an air-flow inlet port that is formed by the left-hand end of heat pipe 26 by the air flow passage that the inside by heat pipe 26 forms.

Smoke 12 has been formed a kind of analogies with cigarette holder 10, and its integral body seems just as a usual cigarette with filter tip.

Adapter 14, it for example is configured to sheet material spare on the whole.According to its left side shown in Figure 1 a sleeve 34 is arranged, it forms one and inserts opening 36, is used for inserting the right-hand end position according to smoke 12 shown in Figure 1.With sleeve 34 separately, adapter 14 is furnished with an insert 38, this insert has two arms that are bent upwards 40 (Fig. 1 has only shown), these arms do not seal into complete sleeve, but can flexibly expand.

A bimetal leaf 42 is arranged between sleeve 34 and insert 38.The position of the general axially parallel shown in it is shown as under normal room temperature then is bent upwards after the heating, will be with sleeve 34 sealings.

A known lighter that is used for smoke-free cigarette of the present invention simply illustrates at Fig. 2, and its integral body indicates with 44.Lighter 44 has main body 46, accommodates fuel in this main body, for example liquefaction gas.A combustion mouth is arranged in the extension 48 of main body 46, and it supplies with air-flow by current path 50, will go out a branch of flame 54 in extension 48 after opening lighter by handle 52.The function of described building block is as follows:

Cigarette holder 10 is coated with a kind of volatile product 58 of enjoying on the medial surface of depressed part 20, for example with fragrance and/or the band fragrance nicotine.Under the deliver goods state, cigarette holder may be by plastic film packaging, and purpose is not allow the product of enjoying 58 evaporate.Cigarette holder 10 can be inserted on the outstanding position 28 of smoke 12 after removing plastic sheeting.Seem that so this assembly is just as a usual cigarette (cigarette holder is together with smoke).

When " lighting ", according to shown in Figure 1, the insertion opening 36 of adapter 14 will be inserted in the end on smoke 12 the right.Then adapter 14 is pulled on the extension 48 of lighter 44 with its insert 38.Can certainly earlier adapter 14 be shifted onto on the lighter 44, cigarette be pushed insert opening 36 then.Relative insertion campaign, be that the extension 48 that smoke 12 inserts sleeve 34 and lighter pushes in the insert 38, can advantageously be defined by the stop of constructing on the adapter 14, thereby when flame 54 presented definite shape, the relative smoke 12 of lighter also made how much coordinations of flame 54 relative heat pipes 26 just be determined thus.In this way, the distortion of bimetal leaf 42 can be harmonious with the heating of heat pipe 26, and enjoy the heating of product 58 and the heating of the lateral surface of the smoke 12 that is held in the hand, thereby under the situation of the corresponding unanimity of heat conductivility of smoke, reached its for example fusion and evaporating temperature of 50 to 60 ℃ although enjoy product 58, and the smoke outside is only by slight heating.

Utilize handle 52 to open lighter, flame 54 enters depressed part 32, and the end portion on heat pipe 26 left sides is heated, and is evaporated or fuses thereby enjoy product 58.If heat pipe 26 is fully heated, that is to say 54 duration of flame abundance, bimetal leaf 42 just is heated and holds up.Like this, cigarette holder 10 is contained in a mouthful interior smoker and just can have turned off and take away lighter 44.

Just can enjoy this cigarette of being made up of cigarette holder 10 and smoke 12 as enjoying a common cigarette after taking down adapter 14, reason is to enjoy product 58 fully to be remained on enduringly on the temperature of enough evaporating by heat pipe 26 owing to the high thermal capacitance of heat pipe 26.When passing through the air-flow of pump orifice 18 inspirations, air-flow is through heat pipe 26, and its break-through opening 30 is along the surperficial position that scribbles and soak into the depressed part 20 that the product of enjoying 58 are arranged, air-flow has just carried composition and other volatile ingredient that the product of enjoying 58 are evaporated like this, thereby can enjoy these compositions in mouth or by sucking.

The size of adapter 14 and lighter are inserted into insertion length dimension in the adapter and cigarette to insert the insertion length dimension of adapter are such, and the short distance that makes the flame point of flame 54 will be in the right-hand end as shown in Figure 1 of heat pipe 26 is concentrated and aimed at heat pipe 26.For the air-flow supply that makes flame is not disturbed by adapter, insert 38 will be configured to allow current path 50 keep basically exposing.Flame 54 is between sleeve 34 and the insert 38 basically.

Can do variation to this invention changes.For example cigarette holder 10 needn't contain filtering material.Depressed part 20 can be configured in the smoke 12, thereby the cigarette holder relative configurations becomes to have an outstanding position.Main body 24 and heat pipe 26 can constitute integral body, and its measure is that watchcase for example can be configured to lamina, and its inside is made by a kind of material that has high thermal conductance and have high heat capacity as far as possible, and be outside then made by a kind of material with low thermal conductivity.Alternatively, main body 24 also can be configured to a kind of multilayer thermal capacitance device that has vacuum between layer.

Heat pipe 26 can be configured to solid heat conductor with high heat capacity and storage heater, and it is made by the material with good thermal conductance ability, and right-hand end wherein shown in Figure 1 will be configured with big as far as possible surface, for example passes through rill.In this case, for example form gas channel by the groove in " hot pin " and/or the watchcase at least along heat conductor, and this gas channel in the depressed part 20 rib and/or the outstanding position of hot pin enter in the cigarette holder.

Adapter also can be configured to other form, for example is suitable for smoke 12 is connected on the cigarette lighter assembly in the automobile.Be heated member so adapter comprises one, it directly contacts with heat pipe 26, and is heated a period of time in the cigarette lighter assembly by adapter is inserted into, and till heat pipe 26 or the abundant heating of depressed part 20 quilts, for example probably reaches 50 to 60 ℃.

Available other lighter replaces described lighter, but need pay the utmost attention to the lighter that has long flame.Can be with a kind of lighter of joining for cigarette of the present invention specially as accessory, its is with predetermined flame combustion, and extinguishes after the preset time section.

The product of enjoying can be that liquid also can be powder, and they are put into 20 li of depressed parts, and the part of cigarette holder will scribble or soak into the product of enjoying.Taste according to the consumer can adopt the different product of enjoying, and for example has nicotine of strengthening mouthfeel and smell or the like.Alternatively also the product of enjoying can be included in the suitable product of the enjoying body, this is enjoyed the product body and can be used as in the tablet threading depressed part, but whole depressed part will be covered as watchcase.Self-evident, can be used as that the product of enjoying carrier that separating member uses must be configured to breathe freely here or have reach through hole, and between the air-flow outlet of original cigarette holder and heat pipe.Especially when using the such product of enjoying carrier, just can reuse original cigarette holder, its measure is that cigarette holder adopts the material of being convenient to clean of health to make.
