Description

Study on Heat-Smoking Cigarettes, Manufacturing Method and Heat-Smoking

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electrothermal smoking cigarettes, and more particularly, to the study of electrothermal smoking used to smoke an electrothermal smoking cigarette.

In traditional cigarettes, the cigarette is heated to a temperature of approximately 800 ° C or more during inhalation of a sip of burning material, which delivers flavor and tobacco smoke to the smoker. When tobacco smoke is sucked through the rear end of the cigarette, the cigarette is incompletely burned. As a result, various gaseous combustion products are discharged. When such gaseous combustion products are inhaled into the human body, the aerosols that provide the flavor and aroma associated with smoking in the human body are cooled to condense.

Such conventional cigarettes cause various problems in smoking, one of which is particularly unpleasant to non-smokers due to cigarette smoke during the smoking, and once the cigarette is lit, it burns to the end or burns in the middle. If you turn it off, you have to throw it away, and you can light it again, but it's not a favorite for smokers because of the lack of flavor and flavor.

On the other hand, unlike conventional cigarettes, there is also a cigarette that does not emit tobacco smoke, which consists of a carbon-based combustibles (heat source) and the tobacco component subsequent to the combustibles located at or near the end of the cigarette, so that smokers match the combustibles When smoking a cigarette by igniting with a lighter or the like, the heat generated from the combustibles is transferred to the tobacco component, which causes the cigarette smoke.

In this type of smoking system, cigarette smoke is rarely produced, but combustion products are produced in the heat source, and once the heat source is ignited, it is not easy to actually turn off the cigarette light for smoking. As a result, all of these conventional smoking devices continue to burn while smoking, resulting in the combustibles decomposing and working with the surrounding atmosphere to increase the production of various byproducts.

U.S. Patent Nos. 5,093,894, 5,225,498, 5,060,671, 5,095,921, U.S. Patent Application Nos. 08 / 380,718 and U.S. Patent Application 07 / 943,504 show that a smoker may stop smoking for a while and may smoke again. Flammables and flavors are listed to greatly reduce the smoke at the tip of the car. Such cigarettes are not very durable and can be broken, torn or broken if handled carelessly, may be crushed in severe cases, and may be torn or cut when removed from a lighter.

On the other hand, the above-mentioned US Patent Application No. 08 / 380,718 and US Patent No. 5,388,594 describe a new heat transfer lighter and a heat transfer smoking device to which the heat transfer lighter is applied. Examples of these electric lighters include a body of a cigarette. It is structured with metal electrothermal absorption research to accommodate the easy insertion.

In addition, US Patent Application No. 08 / 380,718 and European Patent EP-A-0,615,411 have a preferred structure for cigarettes, which includes a cylindrical tobacco accommodating portion for accommodating tobacco, a paper roll and a tobacco accommodating tobacco accommodating tobacco accommodating portion. The filter is provided at the end of the filter and the free end of the tobacco container. With this configuration, if the electrothermal absorption study is operated by suction after the cigarette is inserted into the lighter, carbonization starts to occur locally around the cigarette (hereinafter referred to as the "heater influence zone") by the electrothermal absorption study, and then the heater When all work, the carbonized spots, which are slightly apart from each other, gradually surround the entire tobacco housing.

In this case, discoloration gradually occurs in the tobacco paper carbonized by the high temperature energy transmitted from the heater, and in most cigarettes, fine gaps are formed in the material forming the tobacco paper and the tobacco accommodating portion according to the carbonization. It will weaken tobacco dynamically. Therefore, in order to extract the cigarette from the lighter, the carbonized spot must be partially passed through the heater.If the cigarette is not in a normal state, such as when the cigarette is wet or mishandled, it may be damaged during the removal of the cigarette from the lighter. Some will be left behind. This kind of cigarette left in the lighter can interfere with the normal operation of the lighter or worsen the taste of the cigarette the next time the cigarette is smoked, especially if it is cut off in two when the cigarette is taken out. In order to smoke, it is inconvenient to remove the broken cigarette pieces from the lighter.

In the cigarettes described in US patent application Ser. No. 08 / 380,718, EP-A-0,615,411 and US Pat. No. 5,388,594, a cavity is provided between a filter provided at the suction end of the cigarette and a plug provided at the free end. This structure is designed to minimize the aerosol condensation near the surface of the cigarette and to create more space for the aerosol to exit the tobacco compartment and to deliver more to the smoker. To do that.

Meanwhile, various measures have been proposed to reduce unnecessary smoke at the end of cigarettes when smokers want to stop smoking for a while and continue smoking again. For example, U.S. Patent Nos. 5,093,894 and 5,225,498, Nos. 5,060,671 and 5,095,921 describe various heating components and flavoring devices, while EP-A-0,615,411 and U.S. Patent 5,388,594 disclose that suction is sensed and operated by control and logic circuits. An electrothermal smoking apparatus having a heater is described, which has a relatively thin and serpentine wave shape and a light structure that conducts a moderate amount of heat to a cigarette.

By the way, the above-described electrothermal smoking device or heater can solve some known problems, but it is easy to weaken in terms of structure, and the rod-shaped cigarette is inserted and pulled out. Adjusting or mishandling with a cigarette inserted can cause you to lose strength.

Moreover, if the position of the part is changed, for example by adjusting or mishandling the inserted cigarette, an electrical short may occur, which is undesirable.

In addition, the heater uses an electric resistance heating element of a relatively complicated structure that may cause an electrical short when accidentally inserted or removed from the cigarette.

European Patent EP-A-0,615,411, considering that the interior of the cigarette is filled with the cut tobacco material, the cigarette completely filled with the cut tobacco fuel is properly burned in the electric lighter in the first several suction operations. Later, the release of aerosols will gradually decrease. This phenomenon occurs even when burned in an electric lighter such as described in EP-A-0,615,411.

The hollow cigarettes described in EP-A-0,615,411 tend to break easily if handled at all.

Various characteristic advantages of the present invention are defined by the claims described later. In other words,

Cigarettes in which the present invention is practiced have the advantage that the tobacco material inside is constantly burned when smoking as part of the electrothermal smoking system.

Cigarette according to the present invention has the advantage that the release of flavor and aerosol in the tobacco material stored therein when inserted into the electric lighter to smoke.

Cigarettes in which the present invention is practiced have the advantage that aerosols are uniformly released from the tobacco material contained between inhalation and inhalation.

It is easy to manufacture the cigarette to which this invention was implemented, and the packaging can also be made beautiful.

Cigarettes to which the present invention is practiced are physically durable and do not shrink, minimizing the filtering of aerosols in cigarettes or electric lighters, and less likely to break when extracting cigarettes from lighters.

On the other hand, the cigarette to be smoked with the lighter of the electrothermal smoking system by the present invention is less likely to be damaged or damaged even if the smoker carelessly handled.

Cigarettes in which the present invention is practiced to smoke with lighters of electrothermal smoking systems are less likely to break or break during manufacture or packaging of the product.

The present invention is implemented, the cigarette to be smoked by the lighter of the electrothermal smoking system, it is possible to adopt an efficient manufacturing method in terms of cost and production speed.

On the other hand, the heat transfer study according to the present invention, the smoke can be generated even if the cigarette is not continuously burned to reduce the unnecessary smoke at the end of the cigarette, the smoker can stop and resume the temporary smoking, and smoking Many aerosols are created in the device.

In addition, the electrothermal absorption study according to the present invention allows the smoker to inhale only the required number, and even if the number or duration of the suction operation is changed, the subjective quality of the cigarette is not sacrificed.

The heating element used in the electrothermal absorption study according to the present invention can be structurally suitable for inserting and removing cigarettes.

The heater used in the electrical resistance electrothermal absorption study according to the present invention can be easily connected to the power source used.

The heating element used in the electrothermal absorption study according to the present invention can be mechanically stable during the heating cycle.

The electrothermal absorption study according to the present invention can minimize the deformation of the contact surface between the heating element and the cigarette to avoid the change in the thermal conductivity.

The electrothermal absorption study according to the present invention can be produced more economically.

The electrothermal absorption study according to the present invention, it is possible to provide a smoking system that can smoke smoker with a flavor. The smoking system consists of an electrically operated lighter and a cigarette inserted therein, the lighter having a plurality of heaters installed alone or jointly to release a predetermined amount of high temperature aerosol from the cigarette. The cigarette is intended to have a cylindrical tobacco web (tobacco web), the inner part of the tobacco web is filled with a cylindrical tobacco solid, while the other part is left as a space in the unfilled body cigarette. have.

In more detail, the cigarette comprises a cylindrical tobacco web and a tobacco rod which is contained within the tobacco web and the tobacco solid is contained in the tobacco web, and the tobacco rod is an end opposite to the free end of the tobacco rod in the heating element of the heater. It is inserted and received to be disposed therebetween. In this case, the tobacco rod is disposed only from the free end of the tobacco rod to the space away from the free end of the tobacco rod at a predetermined distance from the opposite end of the tobacco rod, thereby forming a space (cavity) adjacent to the opposite end of the tobacco rod. It is desirable to.

The relative size of the cigarette and the heater portion of the lighter is such that each heating element of the lighter is arranged side by side with the tobacco rod at a predetermined length while contacting the cigarette rod around the cigarette rod so as to insert the cigarette into the lighter, that is, the heater and the cigarette length It extends so as to contact in the direction (heat zone of influence of heater) and overlaps with a part of the above-mentioned space and a part of the tobacco solid, respectively. This results in a consistent and satisfactory release of aerosols when the cigarettes are electrically smoked, and a reduction in the aerosols' condensation on or near heating elements.

On the other hand, the relative size of the heater of the cigarette and the lighter is positioned adjacent to the cigarette rod so that when the cigarette is inserted into the lighter, each heater overlaps a portion filled with the tobacco solid of the tobacco rod rather than all of the heater influence zone. If so, the space will promote the production of aerosols to help cool the smoke.

In this case, the paper rolling cigarette is wrapped in a cylindrical tobacco web to allow the smoker to feel the same appearance and texture as a conventional cigarette.

As the tobacco web, a nonwoven base web and a layer of tobacco flavoring material are preferably disposed along one or both sides of the base web.

The cigarette has a tipping member consisting of a manure filter (called whistle-through plug in the art) at the opposite end of the tobacco rod, a trailing filter and a tip paper for attaching these manure filters to the tobacco rod.

When the cigarette according to the invention is inserted into the lighter of the electrothermal smoking system, the cigarette comes into contact with the stopper (or its equivalent) located in the heater of the lighter, whereby the heating elements of the lighter are all aligned with the cigarette in the same position relative to the cigarette. Can be deployed. When you start smoking, the heater of the lighter described earlier acts to reliably heat the cigarette at a position along the tobacco rod. If the smoking operation continues, the tobacco rod is heated to release the aerosol from the tobacco web and the tobacco filled therein. From the portion where the heater overlaps the space in the tobacco rod, the aerosol immediately exits into the unfilled space in the tobacco rod and is released out of the cigarette.

The tobacco web passes most of the aerosol delivered little by little in the cigarette, which is believed to have an effect on the smoker to feel good when smoking the cigarette. In addition, the release of the aerosol is somewhat delayed from the place where the heater overlaps the filled portion of the tobacco rod because of the solid solid of the filled portion of the tobacco rod. The aerosol released from the filled part of the tobacco rod has a much stronger flavor and tobacco taste than smoke.

Another feature of the present invention is that the amount of aerosol delivery of the electrothermal smoking system can be adjusted, i.e. between the filled and unfilled portions of the tobacco rod when smoking one brand of cigarette and another brand chestnut. The amount of overlapping heaters can be adjusted, or even the cigarette of the same brand can be adjusted by adjusting the amount of overlapping, so that the amount of aerosol delivery can be adjusted as necessary.

The present invention also allows the cigarette to have a free end and the opposite end in a manner that increases the level and consistency of the aerosols emitted from the cigarette heated by the electronic heating device. In this method, the heater is filled with the inside of the cigarette near the free end and the inside of the cigarette near the opposite end on both sides of the space, so that the inside of the inside and the inside of the hollow are heated by a heater and sucked through the rear end at the same time. do.

In addition, the present invention provides a content that is embedded in a cigarette heated by an electric lighter, the cigarette has a filter filter and a space containing no contents adjacent to the filter filter to increase the consistency of aerosol generation Is built in.

In addition, the present invention provides a tobacco web reinforced with rigid cellulose fibers of flax wood added to the base web, it is possible to use the cellulose fibers from the tobacco stem as a reinforcing material of the base web.

The strength of the cigarette is increased by filling the cut tobacco in the cylindrical tobacco web, so that the cigarette can be more robustly handled by the cigarette maker or the smoker.

On the other hand, the heater used in the electrothermal absorption study according to the present invention is composed of a hub serving as a support member, a plurality of electric resistance heater blades for partitioning the space for receiving the inserted cigarette. Each of these heater blades has a first end and a second end extending from the support hub to the first end, a second heater edge having a first end and a second end, and these first angles. It consists of a connecting portion connecting the second end of the first end and the second end of the second corner portion.

The second end of the second corner portion extends toward the hub and is electrically insulated therefrom. An electric resistance heating circuit may be formed in order to heat the heater blades and subsequently heat the inserted cigarettes. The first and second corner portions are arranged to be separated by voids to allow air to pass through to assist in the release of the flavor material from the heated cigarette when the smoker smokes.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, the rear housing part 35 is opened and closed by screws or snap mechanisms so that the battery can be easily replaced. If necessary, the rear housing part 35 is equipped with an electric socket or a connecting means instead of a replaceable battery to be recharged from a home power source. It can also have a built-in battery.

Preferably, the front housing part 33 is detachably coupled to the rear housing part 35 by a dovetail or a socket mechanism. The housing 31 is preferably made of a hard and heat-resistant material, and examples of such a material include metal or copolymer synthetic resin. On the other hand, the size of the housing 31 is preferably approximately 10.7 cm x 3.8 cm x 1.5 cm so that it can be easily held in the smoker's hand.

The battery 35a may be replaced with one having a capacity capable of supplying sufficient power for the heating element 37 to perform a desired function, and may also be rechargeable. Can be mentioned. For this capacitor, it is recommended that four nickel-cadmium battery cells are connected in series so as to have a voltage of about 4.8V to 5.6V under no load. However, the characteristics of the required power source may be selected in consideration of the characteristics of the other characteristic components of the smoking system 21, in particular the heating element 37. For reference, US Pat. No. 5,144,962 describes various useful power sources in connection with other smoking systems in the present invention, which describe rechargeable power sources consisting of accumulators recharged by accumulators and their arrangements. have.

FIG. 3 is a perspective view illustrating a state in which a cigarette is inserted into the heater of the smoking system illustrated in FIG. 1 in more detail. The front heater 33 of the lighter 25 has a cylindrical heater in which a cigarette 23 is inserted therein. It is supposed to support 39. In addition, a plurality of heating elements 37 are accommodated in the heater 39 so that the heating elements 37 are inserted along the cigarettes 23 so that the cigarettes 23 are inserted into and supported by the heating elements 37. It is configured to be arranged side by side at equal intervals. Therefore, the cigarette 23 is in contact with the heating element 37 in a state of being completely inserted into the interior of the heating element 37 bar bar will be referred to as a heater contact portion hereinafter.

In addition, the heater 23 is in contact with the cigarette 23 when the cigarette 23 is inserted into the lighter 25 so that the heating element 37 is positioned at the correct position with respect to each cigarette 34. The stopper 182 is provided. It is a matter of course that the means for fitting the cigarette 23 to the lighter 25 may be used in addition to the stopper 182.

The front housing part 33 of the lighter 25 is also equipped with an electric circuit 41 for transferring a predetermined energy from the power source 35a to the heating element 37, and the heater 39 has a cigarette container ( The eighth element 27 is provided with heating elements 37 having a wave shape concentrically arranged at equal intervals. More details of the heating element 37 are described in US Patent Application Nos. 07 / 943,504 and 5,388,594, and these data are used as reference numbers. In addition, as the heating element 37 having another structure constituting the part of the lighter 25, those described in US Patent Application No. 08 / 291,690 can be cited, and among them, specifically described with reference to FIGS. 13 to 23. Reference may be made to the latter description.

On the other hand, the heating element 37 is to be heated by the heating element 37 is spaced at equal intervals around the cigarette 23 so that each heating element 37 is individually heated by the control of the control circuit 41. It is preferable to allow the cigarette 23 to be heated eight times. According to the heating method as described above, the suction operation can be performed eight times from the cigarette 23 as in the case of smoking a conventional general cigarette. Here, one or more heating elements may be heated in one suction, or conversely, two or more suctions may be set while one heating element is heated.

Other heating element arrangements of heaters include those described in US patent application Ser. No. 08 / 224,848, which is also a reference in the present invention.

2, the control circuit 41 is operated by an intake start sensor 45 that is sensitive to a change in pressure or a change in air flow that occurs when a smoker begins to smoke a cigarette 23. The suction start sensor 45 is disposed in the front housing portion 33 of the lighter 25 and is adjacent to the cigarette 23 via a passage formed by a spacer formed at the bottom of the heater 39. Are connected to each other. If necessary, a sensor tube (not shown) may be disposed in the passage. Examples of the inhalation start sensor 45 suitable for use in the smoking system 21 include those described in US Pat. No. 5,060,671, which is also incorporated herein by reference. As the suction start sensor 45, a silicon sensor of Honeywell's model number 163PC01D35 having an address in Freeport, Illinois, USA may be used. The intake start sensor 45 is configured to operate any one of the heating elements 37 when the air flow detector, which uses the hot-wire wind measurement principle, detects a change in air flow, so that it is heated by the sensor 45 once. When the element 37 is operated, the control circuit 41 controls the current to flow to any one of the heating elements 37.

The display portion 51 is formed of a seven-segment liquid crystal display device. The display unit 51 displays the Arabic numeral " 8 " when the cigarette sensor 53 detects the presence of a cigarette in the heater 39. On the other hand, the cigarette sensor 53 is an optical sensor disposed at the base of the heater 39 to detect that the light is blocked by the cigarette 23 inserted therein. Therefore, the cigarette sensor 53 in turn sends a detection signal to the control circuit 41 so that the display unit 51 can be surely displayed. If the Arabic numeral "8" is displayed on the display unit 51, it means that it can be sucked eight more times, that is, none of the heating elements 37 are operated to heat the cigarette 23. Indicates. After the cigarette 23 is completely burned, an Arabic numeral “0” appears in the display unit 51, and when the cigarette 23 is removed from the lighter 25, the cigarette sensor 53 no longer displays the presence of the cigarette 23. The display unit 51 is turned off without sensing the cigarette sensor 53. The cigarette sensor 53 has to be adjusted so that light is not radiated constantly so that unnecessary power consumption does not occur in the power supply 35a. The detector 53 includes an optical sensor, OPR5005, of OPTEX Technology, Inc., located at 1215 West Crosby Road, Carolton, Texas, USA.

As a display method for indicating the remaining intake water, the display unit of the cigarette sensor 53 may be displayed as "on" "off" whether the smoking system 21 is in operation or not.

One of the several cigarette sensor 53 exemplified as that which can be used in the present invention is a mechanical switch (not shown) which detects only the cigarette 23 present or nonexistent, and a new lighter 25. When the cigarette 23 is inserted, an Arabic numeral "8" or the like may be displayed on the display unit 51 by providing a button (not shown) for resetting.

As a power source used in the smoking device 21 according to the present invention, a control circuit, an inhalation starting sensor, and a display unit, those described in US Patent No. 5,060,671 and US Patent Application No. 07 / 943,504 may be referred to.

Figure 4a is a longitudinal cross-sectional view showing a cigarette according to the present invention, Figure 4b is a perspective view showing in detail the state of the features of the cigarette according to the present invention shown in Figure 4a in detail, as can be seen in these drawings one embodiment of the present invention Cigarette 23 according to the example has a structure in which the tobacco rod 60 and the tipping member 62 is rolled by the end paper 64 is combined.

The cigarette 23 which is not fully filled in is intended to have a constant diameter in the longitudinal direction, the diameter of which is about 7.5 to 8.5 mm in diameter, as in the conventional general cigarette, by the smoking system 21 according to the present invention. The cigarette 23 to be smoked is adapted to feel the texture felt on the smoker's lips. On the other hand, it is preferable that the length of the cigarette 21 according to the present invention is 62 mm so that it is easy to pack with a conventional packaging machine for packing the cigarette 23. And the length of the combined portion of the suction filter 104 and the filter 102 is preferably 30mm. End paper is preferably to be covered by the length of about 6mm on the tobacco rod 60. Therefore, the total length of the tobacco rod 60 is about 32 mm. Other specifications, such as size, length, and diameter, may be appropriately selected in addition to those described above in specific embodiments.

The tobacco rod 60 of the cigarette 23 has a tobacco web 66 which is rolled into a tube (cylindrical) shape. The outer side of the tobacco web 66 is to be fixed along the longitudinal seam while the outer shell 71 is surrounded by the same as in the conventional cigarette. In other words, the outer cover 71 is maintained so as to surround the tobacco web 66 in which the filter 74 and the tobacco solid 80 are incorporated.

The outer covering 71 of the tobacco solid 80 is preferably wrapped so as to surround the tobacco web 66 to have the same appearance and feel as a conventional cigarette. It was found that using the paper used to dry conventional cigarettes is always a good taste for cigarettes. For example, about 20 to 50 Corresta (CORESTA; 1.0 kilopascals in a state where the pressure was reduced to 1 minute. For example, the amount of air measured in cm 3 passing through 1 cm 2 of paper), more preferably between about 30 and 45 Coresta, with a unit weight of about 23 to 35 g / m 2.

In addition, the outer covering 71 should contain little or no citric acid or citrate or other combustion modifiers. The outer covering 71 has a content of citric acid in the range of 0 to about 2.6 wt.%, More preferably. Should be less than 1%.

The tobacco web 66 itself is composed of a base web 68 and a tobacco flavor material 70 disposed along the inner surface of the base web 68. In the rear end portion 72 of the tobacco rod 60, the outer covering 71 and the tobacco web 66 surround the cylindrical filter filtration 74 together. The filter filter 74 forms the rear end 72 of the tobacco rod 60 while supporting the outer cover 71 and the tobacco web 66 so that the pressure of the aerosol from the tobacco rod 60 is lowered slightly. do. In addition, the filter filter 74 serves to compress the flow of air at the rear end 72 of the tobacco rod 60, whereby the smoke is generated while the smoker smokes the cigarette (23) Will be promoted. It is preferable that the filter filter 74 has a length of at least 7 mm to fit a machine for manufacturing a cigarette, and a filter having a different shape and form and having low efficiency, such as other cylindrical filters, may be used.

At the free end 78 of the tobacco rod 60, the outer covering 71 and the tobacco web 66 surround the cylindrical tobacco solid 80 together. The tobacco solid 80 is formed of a relatively short cylindrical cylindrical cut tobacco material formed separately from the tobacco web 66 and rolled into the inner wrapping paper 84.

In addition, the tobacco solid 80 can also be made by a conventional cigarette rod manufacturing machine, the tobacco material (mixed) cut therein is continuously formed on the belt to move the tobacco rod, then ribbon It is continuously rolled up to the inner wrapper 84, which is glued along the longitudinal seam and then attached by heat. In the present invention, however, the inner packaging paper 84 is made of a cellulose fiber web containing little or no fillers, less than 0.5 wt.% Of a combustion changer, and almost no adhesives.

Here, as the inner packaging paper 84, a basis weight of 15 g / m 2 or less, and more preferably, a light unit weight of about 13 g / m 2 or less is used. In addition, the inner packaging paper 84 may be a conifer fibrous pulp, abaca-type cellulose fiber or other long fiber having a permeability of about 20,000 to 35,000 Correstein, more preferably 25,000 to 35,000 Correster. It is better to use what is made of pulp. The paper used as the inner wrapping paper 84 can be purchased from Papierfabrik Schoeller and Hoescht GMBH in Germany, and other papers suitable for use as the inner wrapping paper 84 are carboxy-. A paper having a product standard of TW 2000 produced in DeMauduit of Emperle, France, in which 2.5 wt.% Of methyl cellulose is added may be mentioned.

The tobacco rod 60 made with the tobacco rod maker has a density of about 0.17 to 0.30 g / cm 3, preferably at least 0.20 to 0.30 g / cm 3, even more preferably about 0.24 to 0.28 g / cm 3. do. The manufactured tobacco rod 60 has a high density so that the free end 78 is loose and does not loosen. However, the tobacco rod 60 must have a low density so that the tobacco solids 82 are aerosolized and flavored at the time of smoking. It is important to understand that many passes through. Therefore, the balance between the deterioration of the tobacco solids 82 to increase the passage of aerosols and the end of the tobacco solids 82 to be hardened, and the passage rate of the aerosols worsens.

Tobacco material 84 constituting the tobacco solid 80 is composed of a cut tobacco material mixture typically used in the industry, that is, bright, burley, oriental (Oriental) The use of tobacco and, optionally, mixtures intended to contain tobacco flavor reconstituted tobacco and other traditional tobacco flavors is used. However, examples of cigarettes supplied to the US market include the reconstituted tobacco material or the flavor of the cut tobacco material constituting the tobacco filler 84 such that the ratio of bright, burley and oriental cigarettes is about 45:30:25. The treated tobacco material is not contained. Of course, in order to adjust the density of the tobacco rod, the tobacco material may be further mixed or flavored material may be added.

The tobacco rod formed as described above is formed to have a long length is cut to a predetermined length to make the tobacco solid 80, the length of the tobacco solid 80 to be cut is to be 7mm or more in accordance with the cigarette maker . However, the length of the tobacco solid 80 may be 7 to 25 mm or longer depending on the design of the cigarette, as will be described later with reference to FIGS. 4A and 4B.

In general, the length 86 of the tobacco solid 80 is determined in proportion to the overall length 88 of the tobacco rod 60, that is, the space formed between the filter 74 and the tobacco solid 80. It also depends on the length of (90). The space 90 is a space formed in the tobacco rod 60 and communicates with the tipping member 62 in the second half through the filter 74 of the tobacco rod 60.

In particular, as can be seen in Figure 4a, the length 86 of the tobacco solid 80 and the relative position of the tobacco solid 80 relative to the tobacco rod 60 is determined in relation to the structure of the heating element 37 When the bar 23, ie, the cigarette 23, is positioned at an appropriate position by the stopper 182 of the heater 39, a portion 92 of each heating element 37 is moved to a tobacco rod 60 in a portion of the tobacco rod 60. ) Can be contacted. This contacting region will be referred to as a heater contact portion 94 in the future. This heater contact portion 94 (indicated by the double-headed arrow in FIG. 4A) is not a component of the cigarette 23 itself, but rather a location where the heating element 37 should be effectively heated while smoking the cigarette 23. Corresponds to the displayed area display. Since the heating element 37 is separated by a constant distance 96 from the stopper 182 of the heater 39, the heater contact portion 94 also has a cigarette rod when the cigarette 23 is fully inserted into the lighter 25. The surface of 60 is located at a predetermined distance 96 from its free end 78.

The length of the tobacco solid 80, the length of the heater contact portion 94 and the distance between the heater contact portion 94 and the stopper 182, the heater contact portion 94 is spaced beyond the tobacco solid 80 The portion 90 is arranged to overlap the distance 98. Here, the distance at which the heater contact portion 94 overlaps with the space portion 91 which is an empty space in the tobacco rod 60 will be referred to as a "heater-space overlap 98" from now on. On the other hand, the distance that the remaining portion of the heater contact portion 94 overlaps the tobacco solid 80 will be referred to as "heater-filler overlapping portion".

The tipping member 62 is composed of a filter 102 disposed adjacent to the tobacco rod 60 and a rear filter 104 that is bitten by the lips corresponding to the rear end of the tobacco rod 60. The filter filter 102 has a cylindrical shape and allows air to pass at a considerably low air pressure. Other standard low efficiency filters may be used instead. The inner diameter of the manure filter 96 is between 2 and 6 mm so as to be larger than the inner diameter of the manure filter 74 of the tobacco rod 60.

The rear end filter 104 is coupled to the free end to be visible from the outside to block the rear end of the tipping member 62, if necessary, the rear end filter 104 as a low efficiency filter having a transmittance of about 15 to 25% It can also be configured.

The filter 102 and the rear filter 104 are formed to form the filter assembly 110 by the inner wrapping paper (112). Here, the inner wrapping paper 112 is used to write a light wrapping paper having pores generally used in the manufacture of cigarettes. The filter assembly 110 is to be attached to the tobacco rod 60 by the end paper 64 of the standard generally used when manufacturing cigarettes. This end paper 64 may be decorated by coloring cork, white or any other color.

On the other hand, the cigarette 23 according to the present invention has a total length of about 62 mm, 30 mm of which consists of the filter assembly 110 of the tipping member 62, the length of the tobacco rod 60 It is 32 mm. The length of the filter filter 74 of the tobacco rod 60 is 7 mm or more, and the length of the space 91 between the filter filter 74 and the tobacco solid 80 is preferably 7 mm or more. . In addition, the length of the heater contact portion 94 is about 12 mm, leaving 9 mm in the heater contact portion 94 overlapping the tobacco solid body 80 so that the heater-space overlap portion 98 is 3 mm. It is supposed to be.

The length of the space 91 or the length of the tobacco solid 80 may be adjusted to make it easier to manufacture, or to adjust the smoking characteristics of the cigarette 23 by adjusting the taste and the amount of inhalation and release of the aerosol. In addition, the length of the space 91 and the distance between the heater-filler overlap and the heater-space overlap also improve the consistency of the response and the release (based on inhalation and next inhalation) of the reaction and the aerosol quality of the heater. It can be adjusted to control the condensation.

In addition, the length of the space 91 which is a portion without the filler in the tobacco rod 60 is about 7 mm so that sufficient free space can be secured between the heater contact portion 94 and the filter filter 74. This has the advantage that the heater contact portion 94 does not heat the filter filter 74 while smoking. In addition, in the case where the length may be different, for example, if manufacturing tolerances are allowed, the length of the space 91 may be shortened to be about 4 mm or less, and vice versa. It may be made to be 7 mm or more so that the missing part is long. The length of the space 91 without the filler is preferably about 4 to 18 mm, more preferably 5 to 12 mm.

The base web 68 allows the heating element 37 to be physically separated from the tobacco flavoring material, and transfers heat generated from the heating element 37 to the tobacco flavoring material 70, in the manufacturing and packaging steps. Handling and inserting the cigarette 23 into the lighter 25 or after the cigarette serves to keep the tobacco rod 60 physically engaged while removing the cigarette from the lighter 25.

Next, the ratio level or relative weight of various components constituting the tobacco web 66 will be described. Unless otherwise stated or otherwise obviously recognized by one of ordinary skill in the art, the wt.% Described in the description all refers to dry weight, and the% or relative weights described refer to the moisture content contained (not included). Should be adjusted).

In the process of manufacturing the tobacco web 66, the carbon fiber described later is hardly added. In the manufacturing process of the tobacco web 66, the total weight of the base web 68 is preferably about 35 to 45 g / m 2, more preferably about 40 g / m 2. In order for the total weight of the base web 68 to be 40 g / m 2, the base web 68 should be composed of tobacco fiber of about 28 g / m 2 and cellulose fiber of about 12 g / m 2 from wood or flax. Here, the cellulose fibers serve as a cellulose reinforcing agent in the components of the base web 68. Therefore, as the content of the cellulose fibers of the base web 68, it is preferable that the flavor of the cigarette is contained to the minimum that the paper does not deteriorate. In general, the ratio of tobacco fibers to cellulose fibers of the base web 68 should be in the range of about 2: 1 to 4: 1 based on dry weight. As the material of the cellulose fiber, unbleached cellulose of soft pulp such as softwood is preferable, but other wood pulp or flax pulp may also be used.

In addition, as a material for reinforcing the strength of the base web 68, cellulose fibers made from tobacco lines that are by-products of tobacco production may be used.

On the other hand, one side of the base web 68 is coated with alginate so that the unit weight is about 1 g / ㎡, if the alginate is coated in this way the tobacco flavor of the base web (68) ( 70) shall be coated on the opposite side to which it is applied.

The tobacco flavoring material 70 is attached to the base web 68 to a weight of at least two times, more preferably about 3 to 4 times the base web 68 based on the dry weight. That is, the tobacco flavoring material 70 has a basis weight of about 130 g / m 2 so that the total weight of the tobacco web 66 is about 170 g / m 2. On the basis of dry weight, the tobacco flavoring material 70 is a powdered tobacco raw material and a solid extract is formulated in a ratio of about 3.5: 1 to 5: 1 bar, this blending ratio is about 3: 1 to 9: 1 Although it can be changed within the range of, the most preferred example is a ratio of about 4: 1.

In addition, glycerin is added to the tobacco flavoring material 70 at a dry weight of about 10% to 14%, more preferably about 12%, as a humectant and a precursor, and the added level is tobacco flavoring material (70). Depending on the dry weight of the) may be varied in the range of about 5 to 20%. When the glycerin is lowered by about 5 to 7% with respect to the dry weight of the tobacco flavoring material 70, it is slightly stiff so as not to break when the tobacco web 66 is rolled into a cylindrical shape.

In addition, pectin is added to the tobacco flavoring material 70 by about 0.5 to 20% by dry weight, preferably about 1.4% by weight as a coating agent. If this pectin is not added, the tobacco flavourant 70 penetrates excessively into the base web 68 during the coating operation, resulting in a coarse grained surface of the tobacco web 66. On the other hand, when too much pectin is added, the penetration is hindered, thereby weakening the bond between the tobacco flavor material 70 and the base web 68. Thus, when about 1% of pectin is added, penetration is sufficient to promote bonding between the layers so that the base web 68 can accurately respond to the automation of cigarette manufacture.

And the tobacco flavoring material 70 attached to the base web 68, the extracted tobacco solids in dry weight of about 16 to 20%, the powdered tobacco particles in dry weight 66 to 71%, glycerin about 8 to 14 It is most preferable that it consists of about 1.4% of pectin. Meanwhile, in the cigarette for sale to the US market, the powdered tobacco material contained in the tobacco flavoring material 70 uses a mixture of Bright, Burley, and Oriental cigarettes, and about half of the mixture is Bright. Tobacco, about one-third is burryweight and the rest is oriental tobacco. The composition and relative amount of the mixed powdered tobacco material can be appropriately adjusted according to consumer preference in the US or other markets.

Figure 5a is a process diagram showing the step of processing the tobacco material into a sheet-like tobacco web in the process of manufacturing the tobacco web bobbin of the cigarette shown in Figure 4a, Figure 5b is a tobacco web bobbin of the cigarette shown in Figure 4b It is a process chart which shows the process of processing the sheet-like tobacco web into tobacco web bobbin in a process.

5A and 5B show a method of manufacturing a tobacco web 66 suitable for manufacturing a cigarette 23 with an automated cigarette making machine, wherein the tobacco material shown in FIG. 5A is continuously connected to a tobacco web sheet 66s. A first process of making (step 120 of FIG. 5A) and a process of making the tobacco web sheet 66s of one or more tobacco web bobbins 66b wound around the tobacco web so that it can be used to manufacture the cigarette 23. It consists of two steps (step 122 in FIG. 5B).

Referring to FIG. 5A, the first process of making the tobacco material into the tobacco web sheet 66s starts with the fiber extraction step 124 of mixing the first tobacco material with water to separate the tobacco fibers from the tobacco material dissolved in water. It is. It is preferable to use a tobacco strip as the tobacco raw material, but in this first step, tobacco or tobacco leaves processed in different forms may be used. The tobacco strip is to use a mixture of bright tobacco and Burley tobacco, bar may be optionally oriental or other types of tobacco.

Tobacco fibers collected in the extraction step 124 is transferred to a paper manufacturing process 126 to form a base web sheet 68s formed to be continuous, in this paper manufacturing process 126, the extraction step 124 Tobacco fiber extracted from is released to be dispersed in water together with a predetermined amount of cellulose fiber that serves to strengthen the configuration of the base web (68). The cellulose fiber is made of cellulose produced from wood or flax or tobacco stem. Once the tobacco fibers and cellulose fibers are mixed and subjected to a purification process, the forming step 130 forms a web slurry 128 that is good for making paper. The web slurry 128 is transferred to a molding box of a web forming machine for paper making. It is sprinkled to spread over a wire mesh or spread to spread over an endless belt-type wire mesh. In general, the former method is adopted.

After the two fibers are mixed, it is preferable to once again refine the mixture in which the tobacco fibers and the reinforcing agent are dispersed.

The web 132 after the forming step 130 is followed by a drying step 124 through one or more dryers in the drying step 134, which is a Yankee drier and one or more cans. The web 132 is configured to pass over a can drier. As the dryer used to carry out the drying step 134, a conventionally known technique and apparatus may be used in addition to the dryer. After the drying step 134, the monitoring step 136 is provided to measure the moisture content and the weight of the dried web 132. The output 138 of this moisture content measured result is the drying step 134 so as to maintain and maintain the final moisture content of the base web sheet 68s required to achieve the purpose of the coating operation 144 to be performed next. It is used to adjust the condition of. The moisture content of the base web sheet 68s may be about 15% by weight when the coating operation 144 is performed.

In the monitoring step 136, an output signal 140 relating to the weight of the base web sheet 68s is used to adjust the operation in the molding step 130, so that the base web 68 is preferred as described above. It is to be unit weight This adjustment will include a change in the rate at which the web slurry 128 enters the forming box of the web forming machine in the forming step 130.

The web forming process 126 has a coating step 142 of coating the alginate of the above-described degree on the side opposite to one side to which the tobacco flavor material 70 of the base web sheet 68s is attached. It is. However, you may coat without using the said alginate.

When the web forming process 126 is finished, the base web 68 is shaped to have a conductive base web sheet 68s to allow the coating operation 144 to be placed thereon. Will be collected. However, the coating operation 144 may be performed immediately in the process of forming the base web sheet 68s. Here, the base web sheet 68s may be coated with 144 when the water content is about 12 to 17 wt%, more preferably 14.5 to 15.5 wt%.

In the extraction step 124, the tobacco solution is extracted to produce a tobacco component solution in which the tobacco component is diluted about 5-10%, more preferably 7-8%. This tobacco component solution does not undergo any evaporation process and does not need to be heated to produce a solution. If the heat treatment is to make a cigarette (23) it can affect the taste of the cigarette when smoking.

In addition, the dissolution solution extracted in the extraction step 124, the mixture of the fine tobacco powder, glycerin and pectin is mixed with water in the mixing step 146, the bar is mixed, the relative mixing ratio of the added components The ratio of the components of the tobacco flavoring material 70 described above to a dry state is to be the same ratio as described. In the mixing step 146, after the mixing step 124 is completed, water is sufficiently added so that the solids can be dispersed in about 20 to 35%, more preferably about 24 to 26%. Tobacco powder contained in this mixture is 60 to 400 mesh (mesh) powder, where the term "mesh" refers to the rate of 95% of the tobacco powder passes through a sieve having a through hole per square inch. The added tobacco powder is preferably about 100 to 200 mesh, even more preferably about 120 mesh.

If the particles of the tobacco powder are 120 mesh or more, particularly about 180 to 220 mesh, the slurryed tobacco solids content after the mixing step 146 is increased to a level of about 28 to 31%.

After the mixing step 146, the mixed slurry-like tobacco material can go directly to the coating process 144, this coating step 144 is made by an electrical method after a little off-line. In the coating step 144, the mixed tobacco material slurry should contain about 22 to 27% by weight of solids, more preferably 24 to 25% by weight.

In the coating step 144, the slurryed tobacco material is 4 to 8% by weight, more preferably 5.5 to 6.5% by weight of the tobacco solution. In addition, the slurry tobacco material enters the coating step 144 at a temperature of about 70-130 ° F., more preferably 90 ° F. ± 5 ° F.

The coating step 128 is carried out in a standard counter rotating coater placed behind the Yankee dryer beyond the circulation belt or paper mesh. This coating step 128 may also be done with other suitable coating apparatus that may be known and used by those skilled in the web forming art. The tobacco flavor material 70 may be formed by injection molding or the like on the base web 68. On the other hand, the coating step 128 may be molded in another process separate from the process of manufacturing the base web sheet (68s). Before and after this coating step 12, if necessary, the conventionally used flavoring material is added.

When the coating operation 144 is finished, the tobacco web sheet 66s is made.

Next, as shown in FIG. 5B, after the tobacco web sheet 66s is made through the coating step 144, the tobacco web sheet 66s is wound to be applied to an automated cigarette production machine to the bobbin 66b. Will be made. This conversion step 122 is to be continued in the production process that the tobacco web sheet 66s is made continuously. The operator may cut or tear the tobacco web sheet 66s or other defects so that the tobacco web sheet 66s can be continuously wound into the bobbin 66b without twisting or twisting while the switching step 122 is executed. Care should be taken that no work will be made. In addition, the tobacco web sheet 66s should be able to be easily wound or unwound without any damage to the bobbin 66b since the tobacco web sheet 66s is no longer wound after the conversion step 122 is completed.

The conversion step 122 begins with the drying step 146, i.e., the tobacco web sheet 66s is a gaseous type that can be purchased from Airtech System Corp. of Stroughton, Maine, USA. It is started by feeding to a hot air dryer or a steam hot air dryer. As a facility for forming the tobacco web, other dryers known in the art may be used.

The drying step 146 should be used to minimize the heat, but in the course of the drying step 146, the base web, which was originally about 15%, and the coating material (tobacco slurry), which was about 75%, was dried. At the end of step 146, it should be able to dry so that the overall moisture content of the tobacco web sheet 68d is about 8.5-12%. More preferably, the moisture content of the dried tobacco web sheet 66d should be finally in the range of about 10-11%. Reasons to be the final moisture content as described above, ① to facilitate the splitting operation in the next step following the conversion step 122, ② when the sheet 66d is stored or sent to the manufacturing facility, To achieve a balanced state with the cigarette material, and ③ to ensure that the moisture content does not stick to the bobbin (66b) is wound or wound on the base web.

Tobacco web sheet 66d dried through the drying step 126 is cooled to room temperature, the cooling temperature is preferably such that the temperature of 65 ~ 80 ℃, such as the temperature of the storage location or related manufacturing equipment. The cooling step 148 is to ensure that the tobacco web 66 is adapted to the working environment, as well as to ensure that no heat remains in the bobbin 66b to cause self-heating. If the heat to be cooled in this cooling step 148 is not checked, the heat is increased by the self-heating phenomenon and the characteristics of the tobacco web 66 may be deteriorated. The cooling step 148 is to use the cooling water and the air collision cooler supplied by Airtech System Corp. of Stroughton, Maine, USA, a well-known cooling system supplier in the web forming technology. good.

Tobacco web sheet (66dc) dried and cooled through the drying step 146 and the cooling step 148 is subjected to an ironing step 150, the ironing device used in the ironing step 150 is the state of Maine, USA Ironing equipment supplied by Auburn's Thermo Electron Web Systems, Inc. or other industry known ironing equipment may be used. After the ironing step 150, the tobacco web 66 is not twisted by the edge of the heat enters the winding step 152 and the split step 154, the next step. However, it is desirable to check the temperature and moisture content of the tobacco web sheet 66s and the total weight of the tobacco web sheet 66s when the tobacco web 66 is still in the ironing stage 150 before entering the winding and dividing steps 152 and 154. This is to return the tobacco web sheet 66s to a state in which the tobacco web sheet 66s can be moved into the winding and dividing steps so that the bobbin 66b can have a predetermined temperature, moisture content and total weight.

In particular, in the inspection of the tobacco web sheet 66, the value of the total weight is used to adjust the coating operation, that is, to adjust the feed rate of the slurry of tobacco material fed into the reverse rotation coater or the gap between the coating machine bites. It is used. In addition, the numerical value of the moisture content detected in the monitoring step 151 is used to control the drying operation so that the dried tobacco material sheet 66d described above has a target moisture content. Similarly, the cooling step 148 controls the value of the temperature of the tobacco web sheet 66s in the monitoring step 151.

Thereafter, the tobacco web sheet 66s is wound in the winding step 152, and the winding step 152 is made by a known web winding machine which can be easily found by those skilled in the web manufacturing field. The tobacco web sheet 68s wound through the winding step 152 is divided into a plurality of bobbins 66b, and the width at which these bobbins 66b are cut is determined to be necessary for each cigarette 23. It depends.

At the end of the conversion step 122 the bobbin 66b is in a state suitable for being made into a cigarette 23 in an automatic manufacturing machine, such a process being shown in FIG. 6 in US patent application Ser. No. 07 / 943,504. The description relating to the apparatus may be referred to as it is.

Glycerin in the tobacco flavoring material 70 serves to make the aerosol precursor and aerosol easily visible while smoking the cigarette 23. On the other hand, when glycerin is released into the atmosphere, it is condensed, which makes it look like a typical cigarette smoke when smoked. In addition to this glycerin, other suitable humectants for tobacco production may be used.

After the forming step 123, the alginate is also coated on one side of the base web 68 before and after the coating step 126. When the alginate is coated, the film adds strength to the base web 68. Will be formed. However, it is desirable that the base web 68 be able to have sufficient strength without coating alginate.

In the present invention, it is also possible to use a base web 68 in another form, for example, US Patent Application Nos. 07 / 943,504 and 07 / 943,747, US Patent No. 5,388,594, and European Patent Application EP-A- Carbon fiber mat, metal, or metal screen mat of 0,615,411 is mentioned.

The carbon fiber mats described in European Patent Application EP-A-0,615,411, US Patent No. 5,388,594 and US Patent Application No. 08 / 380,718 are 20 to 30 g / m 2, more preferably about 24 to 28 g / m 2. Most preferably, about 26 g / m 2 tobacco fibers; Carbon fibers in the range of 2 to 9 g / m 2, more preferably 2 to 4 g / m 2, most preferably about 3 g / m 2; It is intended to consist of a base web 68 consisting of pectin of about 0.5-1.5 g / m 2, most preferably of about 1 g / m 2. These components may be balanced to form a base web 68 having a total weight of 30 g / m 2. In addition, it is preferable to use carbon fibers having a 1/4 inch fiber length so that they can be easily dispersed during the slurry formation during the manufacturing process. Regarding the dispersion of the carbon fibers, it can be easily dispersed by adopting a process as described in US Pat. Nos. 4,007,083 and 4,234,379.

As another example of the tobacco base web 66 of the carbon fiber mat, the total dry weight of the drying sheet is about 160 g / m 2, of which 30 g / m 2 is the base web 68 and the remaining 130 g / m 2 is tobacco flavor material ( 70). On the other hand, as an embodiment of the base web 68 containing no carbon fibers, the dry weight of the tobacco web sheet 66s is about 170 g / m 2, of which 40 g / m 2 is the base web 68, 130g / ㎡ is made of tobacco flavoring material (70).

Regardless of which type of base web 68 is used, the tobacco flavor material 70 is disposed on the inner surface of the base web and heated to release the tobacco flavored aerosol. The raw material of the tobacco flavor material 70 may include a continuous sheet of tobacco material or foam, gel (ge1), dried slurry or dried sprayed slurry.

3 and U.S. Patent No. 5,388,594, the free end 78 of the cigarette 23 is formed at the base of the heater 39 when the cigarette 23 constructed as described above is inserted into the insertion portion 27. It is guided into the heater 39 until it comes in contact with the disposed stopper 27. Once the cigarette is in position, smoking can begin, i.e., the operation of the smoker smoking the cigarette is sensed by the sensor 45 associated with the control circuit 41 so that the current is set to the heating element 37. Will be delivered. The current is connected to a conductive wire 183 connected to one end of each heating element 37, an annular ring 184 commonly connected to the opposite end of each heating element 37, and the conductive wire from the annular ring 184. 183 is transmitted through an electric circuit composed of a common line 186 to be returned to the vicinity. When each heating element 37 is heated, the heat energy passes through the outer cover 71 and the tobacco web 66, the tobacco flavor material 70 of the tobacco web 66 is tobacco flavor together with the tobacco rod 60 By releasing the aerosol containing as much as possible, it is possible to reliably suck from the cigarette 23 when the smoker inhales the tipping member 62 of the cigarette (23).

In general, when a smoker smokes a cigarette, the inhalation lasts for about 1.5 to 2.0 seconds. The FTC cigarette test assumes that the inhalation operation lasts for 2 seconds.

In the portion where the heater contact portion 94 overlaps the space 91, the aerosol is directly discharged from the heated tobacco flavor material 70 into the space 91 and into the tipping member 62 in a state where the pressure is hardly lowered. It enters and passes through the smoker's mouth.

On the other hand, where the heater contact portion 94 overlaps the tobacco solid 80 as the portion 99 where the heater and the filler overlap, the adjacent portion of the tobacco solid 80 is connected to the tobacco web 66 by the heating element 37. Starting from near) and gradually heated inside. Thus, the aerosols from the tobacco mixed in the tobacco solid 80 form part of the total aerosol, respectively, thereby contributing to their intrinsic taste and other subjective characteristics. The aerosols emitted from the tobacco solids 80 at or near the heater-filler overlap 99 are introduced into the space 91 through the tobacco solids 80 so that a slight filtration and pressure drop occur. .

The aerosol produced by heating the tobacco solid 80 can be varied in character and taste by adjusting the degree of mixing of tobacco material and the heater contact portion 94 overlapping the tobacco solid 80. In addition, the components of the aerosol generated near the space 91 are released directly from the cigarette 23, which has low thermal inertness in the space 91 and thermally evaporates in the space 91. This is because the degree of the substance is not reduced even if the pressure of the tobacco solid 80 is lowered, but rather, it is transmitted to the tipping member 62 through the filter 24. However, it has a different property from the aerosols emitted from the tobacco solids 80, mainly because it is released from the tobacco flavoring material 70 on the base web 68.

As will be described in more detail below, as a smoker, it was found that the aerosol released from the cigarette 23 was quickly delivered to the smoker, and the flavor which came out of the mixed tobacco material satisfies the smoker's preference.

And, as can be seen in the following description, the presence of the space 91 and thereby the instantaneous release of aerosols at the first inhalation results in higher consistency of suction action and consistency between cigarettes and cigarettes. This relationship can be found in the smoking operation of the cigarette 23 in a completely unfilled form constructed according to an embodiment adapted to have a tobacco solid 80 and a space 91, the first variant of which is illustrated in FIG. The cigarette 23 'according to the example is an example in which no tobacco material is filled in the dried tobacco web 66', and the cigarette 23 "according to the second modification shown in FIG. 7A is the tobacco web 66 This is an example in which the cigarette material is completely filled in. In the description of these modifications, it should be understood that the tobacco webs 66 ', 66 "are all intended to have a base web 68 and a tobacco flavor material layer 70 as described above. The outer cover 71 is rolled up to the rod 60 '.

The comparative data shown in FIGS. 6B and 7B in relation to the cigarettes 23 '23 "shown in FIGS. 6A and 7A, respectively, is performed using a heating element having a waveform set to emit 15 rows of energy. Indicates.

FIG. 6A shows a cigarette 23 'applied to an electrothermal smoking system according to a first variant consisting of a tobacco rod 60' and a tipping member 62 ', in which each component is shown in FIG. 4A. In the example shown, the reference number is indicated with a prime number.

However, the tobacco rod 60 'of the cigarette 23' is not filled with any tobacco material of the tobacco web 66 ', and the free filter 78' of the tobacco rod 60 'has a manure filter 200'. ) Is equipped with the structure. The base web 68 'of the tobacco web 66' contains carbon fibers as described above. The configuration of the cigarette 23 'is also described in detail in US Patent No. 5,388,594, which may be referred to in the present invention as it is. In the following description, the reference numeral 23 of this cigarette refers to a cigarette 23 'of a type in which the inside is not filled with tobacco material.

Figure 6c shows an experiment by connecting the smoking system 21 according to the present invention to a smoking machine that produces smoking. The aerosol from the smoking machine passes through the aerosol measuring device 6y with the transparent chamber 6v during each suction operation, where the light beam 6u from the light source 6w is transmitted to the transparent chamber 6v. Pass through the optical sensor 6z on the opposite side of the chamber 6v. The output of the light sensor 6z is measured by analyzing the density of the light beam 6u when the light beam 6u strikes the light sensor 6z. The aerosols passing through the transparent chamber 6v all exhibit a light scattering effect on the light beam 6u, such that the change in the light density detected by the optical sensor 6z reversely represents the total particulate matter (TPM) contained in the aerosol. do. In the FTC cigarette test, it is advisable to allow the smoking machine to perform a standard two-second suction operation from the smoking system 21.

The data represented graphically in FIG. 6B shows the light density recorded in the aerosol measuring device over time when the smoking operation is continuously performed for the cigarette 23 'which is not filled with a smoking machine. . The above data shows the following trends: the unfilled cigarette 23 'is characterized by the following: ① first and second suction movements do not coincide with the remaining three suction movements, and ② the remaining three suction movements. Are much more consistent with each other. ③ The aerosol is released almost two seconds before each suction operation is performed. The unfilled cigarette 23 'can be seen that the release of aerosol is not constant in the first few inhalations, but much more constant from subsequent inhalations.

In the above data, in the first suction operation, the release of aerosols is generally constant. When a cigarette 23 'is filled with a smoking machine, a hole is punched in the tobacco rod 60'. This is because less aerosols are released during the first inhalation if the measurement results are not calibrated with another meter as described in US Pat. No. 5,388,594.

7A shows an example of an electrically heated cigarette 23 ", which is a tipping member 62 " having a tobacco rod 60 " and similar components to the embodiment shown in FIG. 4A. These similar components will be denoted by double prime ("). However, the cigarette 23" shown in FIG. 7A has a rear end filter ("") at its free end 78 ". 200 " and the cut tobacco rod 220 " extending along the entire length of the tobacco rod 60 " between the post filter 200 " and the filter filter 74 ". This cigarette 23 " Tobacco rod 220 " is comprised of a mixture of burley and bright and oriental tobacco with a rod density of 0.275 g / cm < 3 >. Meanwhile, the base of the tobacco web 66 " The web 68 " is comprised of the carbon fiber described above. In the following description, the cigarette 23 " is a fully filled cigarette 23 ". ).

In FIG. 7B, the results of measuring the light density with the aerosol measuring device 6y show that the light is smoked in a process in which smoking operations numbered from 1 to 7 are continuously performed in smoking a fully filled cigarette 23 ″. It can be seen that there is a correlation between the density and the passage of time, i.e., the data shown in Fig. 7b shows two notable trends in the smoking operation of a fully filled cigarette 23 " F) ① The first few suctions will release aerosols a lot, but the next three suctions will certainly release less than the first few suctions (without calibrating the measuring device), and ② the cigarette will be completely filled (23). In the case of "), the release of aerosol is delayed and the first three suction operations (suction operations 1, 2, and 3) do not achieve the maximum discharge unless two seconds have elapsed.

During the first few inhalations, the fully filled cigarette 23 "will release much more aerosol than the unfilled cigarette 23 '. That is, the data shown in Figures 7b and 6b are compared. The entire area above the line showing the first few suction actions in FIG. 7B for the fully filled cigarette 23 " shows the first few suction actions in FIG. 6B for the unfilled cigarette 23 '. You can see that it is larger than the total area above the line. 7B and 6B, the area above the line indicating each suction operation represents the total amount of aerosols emitted during the suction operation.

However, delaying the release of aerosols in this fully-filled cigarette 23 " prevents the smoker from getting the flavor of the cigarette from the cigarette 23 " fast and must inhale more forcefully. In addition, if the suction force is in this way, the heated portion of the outer covering 71 "and the tobacco web 66" is consumed (burned) too much by the additionally sucked air, and during the first few suction operations, The cigarette rod 220 "may be broken or burst locally. Moreover, once the pyrolysis starts to occur in the fully filled cigarette 23", a large amount of tobacco is burned and it is compressed. There is a tendency to keep such a state. In any case, the air passages that are broken in the first few suction operations can be more easily sucked into the tobacco rod through the damaged “burned” position, thereby shortening the air passages required for subsequent suction operations. It is thought to be. Thus, in a fully filled cigarette 23 ", the release of aerosols in subsequent suction operations is reduced.

In the data shown in Figure 7b, it can be seen that when the cigarette (23 ') or the conventional cigarette completely filled with cigarettes, smoking with an electric lighter, it is consistent with the general trend that the release of aerosols decreases as the suction operation proceeds. .

As such, the release of aerosols is delayed and thermal decomposition of the tobacco material is maintained, so that the fully filled cigarette 23 "tends to produce a large amount of aerosols in the next step of suction operation, and sometimes Smokers may continue to produce a large amount of aerosols over time when they actually want to inhale the cigarette, in which case they will stay within or near the housing 39 of the lighter 25. Generation of residual aerosols ”can be caused. If any such "remaining aerosol" is present, it will condense on the heating element 33 causing problems or stay in the cigarette 23 for a long time during the next inhalation. Either one has an adverse effect on obtaining a consistent tobacco flavor in the cigarette (23 ").

Referring to FIG. 6B, the aeration of the unfilled cigarette 23 'and the line associated with the aeration are maximized (where the suction line is the lowest) before the standard two-second suction time elapses. Since the release of the aerosol is minimized in the suction operation of the next step, it can be seen that the generation of "residual aerosol" is not a problem in the unfilled cigarette 23 '. However, as previously described, the unfilled cigarette 23 'has a lower amount of aerosol emission than the fully filled cigarette 23 ", and the aerosol release is inconsistent in the first few inhalations, if several cigarettes are cut. Even if the materials are mixed (or not mixed), it becomes difficult to exhibit the characteristics and flexibility of the flavor by the mixed tobacco material.

FIG. 8 is a smoking machine in which the aerosol measuring device 6y described above is used, which is configured according to the embodiment of the present invention shown in FIG. 4A and an unfilled cigarette 23 'and a fully filled cigarette 23'. It is the data showing the result of the smoking operation performed on the partially filled cigarette 23. Here, a carbon fiber mat was used as the base web in all the cigarettes (23, 23 ', 23 ”). The data shown in Fig. 8 shows that the cigarette 23 filled with a part of the stomach according to the embodiment of the present invention is more consistent with the release of the aerosol through the entire smoking process. 23 ") will not reduce the release of aerosols in the next inhalation operation, and the aerosols will be released more consistently during the first few inhalations than the unfilled cigarettes 23 '. It is possible.

The partially filled cigarette 23 used in the test for collecting the data used in FIG. 8 is half filled with tobacco material, so that in the design of the cigarette, the portion where the heater overlaps the space is about 6 mm long. In order to obtain the data shown in FIG. 8, a heating element 37 in the form of a waveform generating 15 lines of energy per heating cycle was used.

In particular, the data shown in Figure 8, the amount of aerosols generated during the first two seconds of smoking by the inhalation action while smoking each type of cigarette, respectively, in mg. Analyzing the amount of aerosols shown in FIG. 8 with respect to the data shown in FIGS. 6B and 7B, the integral values (areas above the lines) of the lines associated with each suction operation between 0 and 2 seconds are shown in FIGS. 6B and 7B. You can see a match.

In the data shown in Figure 8, it can be seen that in fully filled cigarettes 23 ", the release of aerosols decreases from the first inhalation to the next inhalation. In contrast, unfilled cigarettes 23 ' It can be seen that the release of aerosols is not reduced, as in a fully filled cigarette 23 ".

8, it can be seen that the partially filled cigarette 23 is consistently discharged of aerosols compared to the unfilled cigarette 23 'during six suction operations. As a result, the cigarette material can be mixed according to the taste and subjective taste of the cigarette.

The data shown in Table II is the data which shows how much the heater overlaps with the space of a cigarette in the cigarette 23 according to the present invention which is partially filled with the inside. The data shown in Table II is for a cigarette machine having a 32 mm long tobacco rod, a 7 mm long manure filter attached to the rear end of the tobacco rod, and a partially filled cigarette 23 having a 30 mm long tipping member. It is from the result of the smoking operation, where the heater contact portion has a length of 12 cm to be concentrated in the middle of the cigarette rod of each cigarette.

Length of heater superimposed along tobacco solid (mm) 11 8 5

9 graphically illustrates the relationship between total particulate (TPM) release and the length of the heater-tobacco overlap (mm). The data presented in this graph were calculated using standard test techniques used to determine the level of FTC "tar" by using a Cambridge Pads to inhale for 2 seconds with a standard smoking machine. In addition, the cigarette used in this test was a cigarette filled with a base web of carbon fiber material and a portion of 58 mm in length. In addition, the data indicated by ordinates in FIG. 9 were a base web made of carbon fiber material and a length of 58 mm. Data obtained from unfilled cigarettes.

Here, the part where the heater and the cigarette overlap can be changed, but the length of the part where the heater contacts is always constant, and is focused on the center of the tobacco rod. Therefore, even if the heater-tobacco overlap is slightly longer, the heater-space overlap is reduced in proportion. The heater is in the form of a waveform having a heater area of about 10 mm. All data presented together in this graph is to represent the correlation between the total fine material ejected in the above environment and the length of the heater-tobacco overlap at intervals of 1 second. From the data shown in FIG. 9 and the data shown in Table II, it can be seen that the length of the heater-tobacco overlap can be adjusted to obtain the level of the amount of aerosol released from the partially filled cigarette 23.

Adjusting the length of the heater-tobacco overlap in order to ensure that the "tar" coming from the cigarette 23 filled with a part of the stomach is at a desired level, and the reason for doing so is to change the heater-tobacco overlap. 80, it is possible to more certainly control the ejection of the aerosol than to change the density of the rod. In addition to determining the tar level, this approach also controls the degree of loosening at the rear end by selecting the density of the tobacco solid 80, and the pressure level at the free end 78 of the tobacco rod 60. The degree of reduction and filtration should be as desired and made easy to manufacture. It is also possible to change the release of tar in the associated cigarette product without necessarily changing both the tobacco web 66 or the tobacco solid 80.

In addition, if all of the heater contact portions are not located on the tobacco solid 80, which is the filled portion of the tobacco rod 60, the relative dimensions of the partially filled cigarette 23 and the heater 39 of the lighter 21 In this way, there is an advantage that at least some of the heating elements 37 can be arranged along the tobacco rod 60 when the cigarette 23 is inserted into the lighter 21. In such a form, the presence of the space 91 facilitates the formation of the aerosol and serves to lower the temperature of the aerosol. In addition, the filtering filter 74 flows so that the aerosol component is compressed from the large space 91 to help the aerosol is generated. In this regard, the filter 74 of the tobacco rod 60 is provided with end portions 73 and 75 on both sides thereof, one end 73 of which is followed by a space 91 and the other end 75 with another filter. 102 is to be connected. Since the end portions 73 and 75 have an inner diameter smaller than the inner diameter of the space 91 surrounded by the filter filter 102 or the space 91 where the filter filter 74 has an inner diameter adjacent thereto, The inner diameter of the space portion is smaller than the inner diameter of both space portions. Thus, at these end portions 73 and 75 and the portion of the manure filter 74 adjacent thereto, a flow such as turbulent flow, which is good for aerosolizing the gas and particulates emitted from the heated tobacco portion of the tobacco rod 60, is produced. .

Fig. 10 shows another embodiment of a cigarette according to the present invention, wherein a cigarette 23a according to this embodiment has a constituent member arranged as described in the cigarette 23 shown in Fig. 4A, while The free flow filter 78a is further provided at the free end 78a of the tobacco rod 60a. The backflow filter 200a is for preventing tobacco material from the free end 78a from the tobacco solid body 80a. The filter 200a is not ignited by a lighter or a match like a general cigarette, but is electrically heated. They are painted to indicate that they are used in the system. Here, the backflow filter 200a is shown separately from the packaged tobacco solid 80a, but when the cigarette 23a is manufactured, the backflow filter 200a is used as a wrapping paper (not shown). It is convenient to manufacture cheaply.

By arranging the backflow filter 200a, the cigarette 23a is not worrisome even if the density of the tobacco rod is not tight and there is no fear that the tobacco material may escape from the tobacco rod 60a.

As described in EP-A-0,615,411 and U.S. Patent Application Nos. 07 / 943,504 and 5,388,594, the backflow filter 200a is a free end 78a of the tobacco rod 60a when the suction operation is completed. C) from the free end 78a in relation to the role of preventing some or all of the aerosol leaking from the air and the amount of air entering the side of the tobacco rod 60a so that the pressure at the free end 78a is lowered. It serves to properly limit the amount of air sucked into 23a.

With regard to the design of the partially filled cigarette 23, the heat of the heater and the length of the heater-tobacco overlap can be used to ensure or adjust the desired "tar" emission level. Accordingly, in newly designing the partially filled cigarette 23, by selecting the density of the tobacco rod of the tobacco solid 80a, the aerosol pressure at the free end 78 can be lowered as desired or the backflow can be controlled. The same result can be obtained by the backflow filter 200a in the filled cigarette 23a which is another structural example.

11 is a longitudinal cross-sectional view of a cigarette 23b according to another embodiment of the present invention. In the cigarette 23b, the low-density portion 320b is a cigarette when the tobacco solid 80b is adjacent to the space 91b. Adjacent to the free end 78b of the rod 60b, the high density part 320b is formed, respectively. In the cigarette 23b, the heater contact portion 94B overlaps the low density portion 310b of the tobacco solid body 80b so that a large amount of aerosol can be released from the tobacco rod of low density. On the other hand, the high-density region 320b of the tobacco solid body 80b is disposed to avoid loose ends, thereby restricting air from passing through the tobacco rod 60b in the axial direction similar to the backflow filter 200a.

12 to 21 are views showing a heater employed in the electrothermal absorption study according to the present invention. These heaters are adapted to be applied to the various examples of cigarettes described above, i.e., not fully filled, partially filled, or filled in FIGS. 4A, 4B, 6A, 7A, and 10 and 11. It shows a heater that can be applied to a cigarette or a modification thereof.

These heaters have enhanced mechanical strength in preparation for repeated insertion, adjustment and removal of the cigarettes 23, in particular to increase the production of aerosols from the heated cigarettes while the required heating conditions continue. Here, it can be seen that the resulting aerosol tends to flow from the heated heater towards the center.

In general, the heater is equipped with eight heater blades 121, the eight heater blades 121 are continuously ignited to perform eight suction operations, so that the suction operation such as inhalation when smoking a general cigarette can be made. It is. In particular, the heater blade 121 extends from the hub 110 to be arranged in a cylindrical shape so that the cigarette 23 can be inserted into the inside. In addition, the gap 129 at a predetermined interval may be formed between the heater blades 121.

On the other hand, the number of the suction operation may be changed when smoking the cigarette 23, in order to do so by changing the number of the heater blades 12, the cylindrical receiving portion consisting of this changed number of heater blades 12 ( Inserting the cigarette 23 into the CR) allows the number of suction operations to be changed. The desired number of suction operations can be achieved by forming the number of heater blades 121 in accordance with the desired number of suction operations. In addition, the above-described results may be achieved even if the sizes of the heater blades 121 used are all the same or not the same.

The heater is arranged at the orifice 27 in the lighter 25. The cigarette 23 is first partitioned by an annular cap-shaped support member 83 having an open end for receiving a cigarette from the counterflow filter 200, which is optionally installed, into the orifice 27 in the lighter. It enters into the cylindrical space part of the heater 39, The cylindrical space part is a cylindrical air passage sleeve 87, the heater blade assembly 100 consisting of a plurality of heater blades 121, the heater blade assembly A conductive pin or lead 104A, a conductive anode pin or lead 104B for supplying current to the heating element 100, and a spacer are provided. In addition, the bottom inner surface 81 of the spacer is stopped after the cigarette 23 is inserted into the desired position in the heater 39 so that the heater blade 121 is positioned adjacent to the surface of the cigarette 23. The preferred embodiment of this cigarette is as described above with reference to FIGS. 1 to 11.

In addition, most of the heaters 39 are fixed to the inside of the front part 33 of the housing 31 of the lighter 25 by a junction portion that fits therewith. In addition, the front end 93 of the support member 83 extends a little further out of the first end 29 of the lighter 25 so that the cigarette 23 guides when the cigarette 23 enters or exits the heater 39. It has a slanted or rounded face. The rear end of the heater 39 is provided with pins 104A and 104B so that the heater 39 is supported in the lighter 25 by being inserted into a socket (not shown). It is intended to flow current from the socket to various electrical elements. In addition, a pin may be additionally installed to reinforce the configuration of the pin. The pins 104A and 104B may be made of a suitable material having electrical conductivity, and may be made of tinned bronze bronze. The passage 47 formed in the spacer and the base 50 communicates with the suction motion detecting sensor 45, while the light sensor 53 detects whether or not a cigarette 23 exists in the lighter 25. It is.

As shown in FIGS. 12 and 13, the heater blade assembly 100 includes eight heater blades 121 symmetrically arranged extending from the central hub 111, or as shown in FIG. It is of an asymmetrically arranged structure described with reference to 19. As shown in FIG. 13, the heater blade assembly 100 has a cylindrical opening 360 that forms a passage 365 formed so that the inserted cigarette 23 is inserted in the axial direction from the cylindrical receiving portion CR. The accommodating portion CR is smaller in diameter than the opening portion 360. The opening 360 is partitioned by each tip portion 118B of the connecting portion 118 of the heater blade 121, and the passage 365 consists of a connecting portion 118 between the connecting end portion 118A and the tip portion 118B. You lose. In addition, the diameter of the opening 360 is larger than the diameter of the inserted cigarette 23 to guide the cigarette 23 toward the receiving portion CR, and the diameter of the receiving portion CR is approximately cigarette 23. It is to have a diameter such as to transfer heat energy well to the cigarette (23).

The cigarette 23 is preferably to have a diameter substantially the same as the diameter of a conventional general cigarette. In view of the manufacturing tolerances of the cigarette 23, the portion or the passage 365 where the diameter between the distal end and the receiving portion CR gradually narrows, the peripheral heater blade serving as an inner wall surface of the receiving portion CR ( It may be pressed to increase the thermal contact with 121). Although not limited, the inner diameter of the opening 360, which is the insertion end, may be about 0.356 ± 0.02 inches (inch), and the inner diameter of the receiving portion CR is about 0.278 ± 0.02 inches. Do. In addition, the heater blade 121 is bent toward the center to reduce the diameter of the cylindrical receiving portion to increase the thermal contact force to the cigarette (23).

Each of the U-shaped heater blades 121 includes a first corner portion 116A extending from the hub 11, a connection portion 118 connected to the other end of the first corner portion 116A, and The second corner portion 116B extends from the first corner portion 116A to the hub 11. These first and second corner portions 116A, 116B are separated by gaps 125 having substantially the same width, and are arranged substantially parallel in a non-cylindrical state as shown in FIGS. 18 and 19. To achieve the state, the cigarette is inserted in a continuous direction to prevent the inserted cigarette is broken, and when rolled in a cylindrical shape serves to form a receiving portion (CR) for accommodating the inserted cigarette (23).

On the other hand, the connecting portion 118 has a curved connecting end 118A connecting each opposite end of the first and second angles 116A, 116B, as described in more detail below. A long U-shaped closed passage extending in the same direction as the axis of the cigarette to be inserted is arranged side by side with the cigarette. The curved connection end 118A has a curvature of about 180 ° ± 20 ° to form a U-shaped heater blade, and is concave toward the hub 111 and convexly curved toward the opening 360. have. In addition, the first end portion of the first corner portion 116A is formed to have the same thickness as the width of the hub 11 is widened, and at the distal end portion 115, compared with the other portions of the first corner portion 116A. Relatively low current density and low power density to reduce the heat generated in the end portion (115). In addition, the width of one end portion of the first corner portion 116A is thus widened so that the mechanical integrity of the heater blade 121 in the hub 111 can be increased.

On the other hand, the second end portion 122 of the second corner portion 116B is raised to form a step relative to the body portion of the second corner portion 116B is easy to be electrically connected to the positive pin (104B). In particular, as shown in FIGS. 12 and 13, the second end portion 122 of the second corner portion 116B is divided into three parts, that is, an extension portion continuously flat to the second corner portion 116A. 122A, the transition part 122B bent as shown, and the connection end part 122C extended in parallel with the extension part 122A following this transition part 122B.

In addition, the second end portion 122 of the second corner portion 116B is wider than the body of the second corner portion 116B so that the strength is reinforced, so that the connecting end portion 112C contacts the positive pin 104B. In addition, the current density at the second end 122 can be reduced to reduce the generation of heat. The connecting end 122C may be wrapped in an adhesive with the positive electrode pin 104B and connected to each other, or may be connected by other electric welding or mechanical connecting means.

14 and 15 show another example in which the heater blade 121 is thermally connected to the positive electrode pin 104B. Here, unlike the example shown in FIGS. 12 and 13, the second corner portion 116B of the heater blade 121 does not have a step shape, and the second corner portion 116B itself is configured to extend flatly, as described below. It can be easily assembled together. On the other hand, there is a possibility that a short circuit occurs at the contact portion between the distal end portion 122 and the distal end portion 115 of the hub 111 or the first corner portion 116A when the inserted cigarette is twisted or a smoker tries to change the inserted state. In order to reduce, the connection end 122 and the hub 111 and the end portion 115, in particular, each of the contact surface of these members is to be electrically insulating ceramic coating (300).

The ceramic coating 300 is applied to the hub 111, the connecting end 122 and the distal end 115 of the first corner 116A by a conventional coating technique such as plasma spray. The ceramic used in the ceramic coating 300 is selected to have a relatively high dielectric constant, such ceramics, such as alumina, zircon oxide, mullite (cordierite), spinel, posterite ( fosterite) and mixtures thereof.

On the other hand, when using a ceramic such as zirconium oxide having the same thermal expansion coefficient as the base metal heater so as to avoid a difference in the expansion rate and the shrinkage rate during heating and cooling, cracks do not occur or the film falls during smoking. That is, even when the heating element is heated, the ceramic layer is maintained in a physically or chemically stable state. In order to make the ceramic layer electrically insulated, the thickness is preferably about 0.1 to 10 mils or about 0.5 to 6 mils, more preferably 1 to 3 mils. Here, the connection end 122 is preferably not coated, so that the anode pin 104B described above is connected to the unexposed portion. Further, in order to simplify the shielding, the distal end 115 associated with the connecting end 122 is likewise not coated with ceramic.

In the above-described plasma spraying step, the ceramic as described above may include the gap 127, the second end 122, and the hub () between the connection end 122 and the distal end 115 of the first corner 116A. Applied to the gap 126 between the 110 to form a ceramic hub to structurally integrate the heater blade assembly as shown in FIG. The size of the ceramic hub may be larger than that shown. The additionally applied ceramic, ie, the ceramic coating, is to be electrically insulated from the second end 122 connected to the anode pin 104B, and the gap 127 and the gap 125 are formed in response to a short circuit. Protective measures can be narrowed down. Accordingly, the second end portion 122 and the distal end portion 115 of the first corner portion 116A may have a wider area, thereby further strengthening the cigarette accommodation portion, and in the case of a hub made of ceramic, reinforcing the skeletal structure. This makes the heater blade assembly more robust.

In addition, the ceramic coating as described above, the sharpness of the edge of the edge partitioning the gaps (125, 127) is purified, especially when the smoker inserts, removes or adjusts the insertion state, the cigarette will be broken or damaged The likelihood is reduced. On the other hand, the entirety of the heater blade 121, in particular the entire outer surface of the first and second corner portions 116A, 116B that do not face the cigarette, or coating both the inner and outer surfaces, or the gap 125, 127) is coated with a ceramic layer, such as 2 mil thick zirconium oxide, to reinforce the heater blades while maintaining the width of the gap to the required width. Therefore, the thickness of the heater blades 121 can be made thin so that the thickness of the heater blades 121 is about 2 to 6 mils, so that the electric resistance of the heater is increased, and the inserted cigarette 23 and the heat while the resistance of the entire heater blade are maintained at the same value. The area in contact can be widened. The wider width of the heater blades and the ceramic layers coated on them make the structure of the heater blade assembly stronger. In addition, the ceramic layer coated on the surface of the heater blade 121 not facing the inserted cigarette prevents heat from being lost from the heated heater.

The ceramic coating is preferably coated by the method described in the plasma spray or related parts, and is preferably deposited with an electron beam so that residual stress does not occur due to surface treatment or particle impact during plasma spraying.

Each heater blade 121 forms a resistive heating element. That is, the first end 115 of the first corner portion 116A is electrically connected to the negative terminal of the power source, and in particular, the hub 111 itself is extended or mechanically or electrically connected to the hub 111. In other words, the cathode terminal pin 104A is soldered to the negative electrode pin 104A or soldered with brass or lead to be electrically and mechanically connected. The cathode terminal pin 104A is provided with two to support the balance, because the connection between the cathode and the anode serves to mechanically support the heater on the one hand. Here, the hub 111 serves to electrically conduct all of the heater blades 121 together. Further, in all the above examples, the negative electrode terminal connected to each heater is configured to contact the negative electrode contact portion formed at an end of the heater opposite to the second end 122 contacting each positive electrode of the heater, for example.

As described above, the connection portion to which each anode is connected to each heater blade 121 is configured to include a connection end portion 122C corresponding to the second end portion of the second corner portion 116B. The connecting end 122C is electrically insulated from the common connecting hub 110 by the gap 127, while the first corner 116A of the heater blade assembly 120 is particularly provided by the gap 125. It is insulated from the end 115, and is insulated from adjacent heater blades by the gap 131 so as to allow a short circuit and thermal expansion. On the other hand, the ceramic coating described above may be selectively applied. The connection ends 122C are grounded, respectively.

The positive and negative connections described above form a resistance path and an electrical resistance path that forms an electrical circuit for supplying current from a power source, for example, via a control circuit, in particular allowing the heater blade assembly to activate the smoking system according to the smoker's suction action. . The heater blade is heated to be the first corner portion 116A, the connection portion 118A, and the second corner portion 116B. Therefore, the cigarette 23 placed in the heated heater blade 121 and inserted into contact is heated to an outer surface shape in contact with the heated portion of the heater blade 121, that is, in the heater blade 12. Conductive and radiant heat with some convective heat that takes place is placed on the surface of the cigarette and heated to a U-shaped outer surface that is long, like the shape of the heater blades in contact.

On the other hand, the surface of the cigarette placed under the gap 125 between the corner portions 116A and 116B is heated by overlapping or crossing the radiant and conductive heat transmitted from the corner portions 116A and 116B. If the gap 125 is too large, the overlap of the desired heating zones does not occur, so that the cigarette portion placed on the gap 125 is not properly heated. In addition, the radiant heat and the conductive heat heat the thermal contact portion of the outer surface of the cigarette to slightly exceed the outer edges of the respective portions 116A and 116B. The various heated portions of the cigarette 23 together form a heating zone. The heating zone extends slightly beyond the outer edge of the first corner portion 116A under the first corner portion 116A, while the gap ( It extends slightly beyond the second corner portion 116B beyond the second corner portion 116B beyond the second corner portion 116B, so that all of the generated tobacco flavor can be inhaled.

The size of the heating zone is determined by the size and thermal characteristics of the heater blades and the amount and period of the energy pulses. That is, the size and thermal design of the heater blade should be designed to maximize the heating of each part of the cigarette to be inserted, for example, when the area of the heater blade is 18 mm2, the smoker operates by the suction operation In response to the pulse, aerosols can be produced to the extent that a smoker can inhale.

The end portion 115 or the second end portion 122 having a relatively large width forming a part of the current path has a relatively large volume and a low current density, so that heating is not performed at such an operating temperature, thereby reducing the amount of heat generated. In addition, the connecting portion 118 is not heated at this operating temperature because the current path tends to be along the edge of the connecting portion 118A, and the distal end 115 or the second end 122 is relatively bulky. Cursor is not heated than the connection portion 118A or a portion thereof.

In order to prevent the remaining portion of the connecting portion 118 from being unnecessarily heated, (1) as shown in FIG. 14, the thickness of the integral connecting portion 118C of the connecting portion 118 is curved. To make it thicker than to reduce the current density and heat generation, or (2) to drill the connection portion 118 to reduce heat generation and thermal conductivity, or (3) as shown in Figure 6, A heat sink material 119 that absorbs heat on 118 is added to reduce heat conduction at connection 118.

In order to achieve the heat sinking action, for example, a non-conductive material that insulates heat, such as ceramics, is used. Such ceramics are oxidized with aluminum oxide, zirconium oxide, and these aluminum oxides as the coating of the heater blades. And mixtures of zircons and mulites. All of these ceramics should be evaluated for adversely affecting the mechanical integrity of the connecting portion 118 that supports the heater blade assembly 100 and forms openings through which cigarettes are inserted and removed.

There is a minimum set waiting time for the suction operation even after the current is transmitted to the heater blade 121. Heating the cigarette portion too quickly causes aerosols to form in the portion of the cigarette, or the heat deteriorates the taste of the cigarette before the desired heating takes place. In other words, once the heated part is heated again, bad flavor and taste are produced.

If only one heater blade has to be heated and longer suction is required to obtain the required aerosol, either another heater blade or another heater blade is heated immediately after the first heater blade has been heated, or the first heater blade While it is being heated, other parts of the cigarette should be adjusted to heat. The heater blade added to the another one may be composed of a heater blade continuously connected in the radial direction or a heater blade separately. And the heater blade should have a size that can suck the aerosol by a predetermined suction operation at a predetermined time.

For example, the number of heater blades 121 is set to eight so as to match the required number of suction operations. In another example, the number of heater blades 121 is to have two heater blades for each suction operation, that is, the area of cigarettes divided into sixteen is inhaled and smoked eight times. Such a configuration proceeds differently from the conventional one that burns for about two seconds, so that in the example in which the number of heater blades 121 matches the number of suction operations, it is possible to continuously burn radially. For example, heating the cigarette at the same time so that the logic circuit is circumferentially opposed to the heater blade 121 disposed, ie, the heater blade 121 disposed 180 ° away from the cylindrical heater blade assembly. Make it as instructable as possible.

On the other hand, the first heating sequence of every one of the heater blades 121 for heating the cigarette is followed by the second heating sequence of those intermediate heater blades 121 for smoking the next cigarette. This first heating sequence is repeated for a given lifecycle of many cigarettes and then the second heating sequence begins. And you may mix and apply the above heater blades. In addition, the number of heater blades may be less than, equal to, or more than that of the number of suction operations when smoking cigarettes intended to smoke one by one. For example, a heater blade assembly with nine heater blades may be applied to a cigarette that has been inhaled six times, in which case six of the nine heater blades are still used when smoking a cigarette, but the remaining three are not heated. Will remain.

The heater blade assembly 100 is configured such that the hub 110 is mechanically and electrically fixed to the cathode pin 104A by the second end 122 to the cathode pin 104B by welding. The pins 104A and 104B may be molded into a hub made of plastic in advance and integrated or connected to be fixed to the hub to minimize leakage of air. This fixed rear end is positioned opposite the opening 360 into which the cigarette is inserted. In addition, the connecting portion 118, in particular, the connecting portion 118A and the other end portion 118B is intended to partition the opening 360, the tip portion 118B is opened toward the outside to the passage 365 Will form. After passing through the passage 365, the diameter of the heater blade assembly 100 is gradually narrowed to be slightly smaller than the outer diameter of the cigarette 23 to be inserted, and a compressive force acts between the heater blade 121 and the cigarette 23 at the intermediate point of the blade. The predetermined thermal contact can be made. The tongue 118B is not fixed in order to be easily expanded when heated.

More specifically, the tip 118B is to be located in the through passage 210 disposed on the inner wall 210 of the lighter end cap 83, in particular, the heater blade 121 positioned to be inwardly inclined. The distal movement of the tip portion 118B outward in the radial direction is constrained by the tip portion 118B contacting the radial bar-like wall of the through passage 210, thereby establishing a limit of bias and shifting inwardly. It can be defined. Such bias can be compensated for by installing the inward facing components as described above.

As shown in the figure, the inner wall 201 of the channel 200 extends outward so that a cigarette can be inserted. The outer wall of the channel 200 in contact with the tip 118B of the heater blade 121 is designed to have a size and shape to which the tip 118B of the heater blade can be inserted, so that the heater blade is heated or cooled, or The tip portion 118B does not escape from the passageway 210 while the cigarette is inserted or discharged. If necessary, the inner wall 201 of the channel 200 may be trapezoidal in contact with the tip 118B to function as a pedestal. As another example, the portion 118D of the tip portion 118B may be rounded, more specifically, the tip portion 118B to be formed in an elliptical shape. The heater blade portion into which the elliptically rounded portion 118D is inserted is supported in the through passage 210 to move in response to a thermal or mechanically induced moment, thereby allowing the heater blade 121 to pass through the through passage 210. It is possible to maintain the state inserted in the). Here, of course, the tip portion 118B may be more rounded.

12 shows an example of a heater used in the present invention. In this example, when the size of the through passage 21 is a cigarette 23 is inserted or the heater blade 121 is heated, The front end 118B of the heater blade 121 is extended to a predetermined amount toward the rear end surface 202 so that a predetermined contact can be made between the cigarette 23 and the heater blade 121. It is. In addition, one end of the heater blade 121 is disposed so as to be relatively free with respect to the hub positioned to face the opposite side, the heater blade 121 in the longitudinal direction when the cigarette is inserted or removed or the heater blade is heated or cooled The stress is reduced by receiving mechanical movement or expansion or contraction by heat.

FIG. 14 shows another example of a heater used in the present invention. In this example, a trapezoidal pedestal 204 is disposed in the through passage 210 so that the heater blade 121 is heated and expanded when a cigarette is inserted. Or move to form a support point such that the tip 118B of the heater blade 121 is brought into contact with the pedestal 204 so that the heater blade 121 is displaced toward the inserted cigarette 23, thereby being applied to the heater blade. It is intended to reduce the stress so that the thermal contact between the heater blades and the cigarette can be increased to the required level. On the other hand, such a support point usually means that the heater blades 121 can be easily rotated, but the pedestal 204 will not be understood so much but should be less than the point supporting the movement.

On the other hand, the heater blade assembly 100 is preferably coated with a ceramic as described above to form an integral. The hub 111 and the heater blade 121 are made of a material having the required electrical resistance and mechanical strength. Among them, a heater blade 121 made of a material having a required electrical resistance of about 50 to 500 μohm cm, more preferably about 100 to 200 μohm cm, pulses of about 10 to 50 Joule, more preferably about 10 to 25 Joule, In particular, when heated for about 0.2 to 2.0 seconds with a pulse of 30 Joule, the temperature reaches about 200 to 1000 ° C, preferably about 400 to 950 ° C, and more preferably about 300 to 850 ° C. The material for making the heater blade 121 should be one that does not interfere with the strength even in about 1800 to 10000 pulses, the material does not deteriorate, and the heater blade 121 does not need to be bent.

The material from which the heater blade 121 is made should be selected from reliable ones that have been guaranteed to operate without defects even after 1,800 on / off repetitive operations. In addition, the heater 39 can be handled separately from the power source 37 and the lighter 25 provided with the circuit element, so that the heater 39 can be changed after 3600 times or more. The material of the heater and other metallic members are also selected on the basis of oxidation resistance that should not be oxidized at a predetermined temperature, no general chemical reaction that should not adversely affect the cigarette 23, and the like. If necessary, the heater blade 121 and other metal members may be encapsulated with an inert thermal conductive material such as ceramic to avoid oxidation and chemical reaction.

However, the heater blade 121 and the other metal member are made of an alloy having a heat resistance with high resistance to mechanical strength and surface oxidation and corrosion and material sensitivity at high temperatures. In addition, the heater blade 121 is preferably made of a material exhibiting high mechanical strength and surface stability even at a temperature of up to about 80% of the melting point. Such alloys are commonly referred to as superalloys and generally alloys based on nickel, iron and cobalt. That is, iron or nickel alloys containing aluminum and yttrium are suitable. In addition, it is preferable that the alloy forming the heater blade 121 contains aluminum so as to have oxidation resistance in order to improve the performance of the heating element.

Preferred materials include alloys containing iron and nickel aluminide, the most preferred of which are those described in US patent application Ser. No. 08 / 365,952.

Some additional components may be added to the Ni ₃ Al alloy. In the alloy material used for the second end 122 of the heater blade 121, B and Si become important elements. Here, B is presumed to increase grain grain boundary strength and is most effective when Ni ₃ Al is rich in nickel with Al ≦ 24 at,%. Si is not added much in Ni ₃ Al alloy, because when Si exceeds 3 wt.% At most, it forms a silicate of nickel and Si is oxidized to SiO _x . Adding Mo makes it possible to increase the mechanical strength at low and high temperatures. Zirconium helps to increase oxide spalling resistance during thermal cycling. Hf (hafnium) can also be added to increase the mechanical strength at high temperatures. Preferred Ni ₃ Al alloys used for the adhesive surface 300 and the second end 122 of the heater blade 121 may be referred to as IC-50, which is a semi-nest lane hold in New York in 1994. About 77.92% Ni, 21.73% A, in Table 4 of the paper entitled "Processing of Intermetallic Aluminides" in the book "Intermetallic metallurgy and Processing Intermetallic Coumpound" published by Van Nestrand Reinhold. It consists of 0.34% Zr and 0.01% B.

Various components may also be added to the iron-aluminum alloy, and the components that may be added include Nb, Cu, Ta, Zr, Ti, Mn, Si, Mo, and Ni. The material of the heater is a nickel-based alloy containing 16.0% of chromium, referred to as Haynes Alloy No. 214, which contains 3.0% of iron, 4.5% of aluminum, traces of yttrium, and about 75%. Consists of the remaining ingredients, it can be purchased from Haynes International of Como, Indiana, USA. In addition, alloys sold under the brand names Incotel 702 alloy, McrAIY alloy, FeCrAIY alloy, and Nichrome may be used, among which the alloy of the Nichrome brand is used. Silver nickel contains 54 to 80%, chromium 10 to 20%, iron 7 to 27%, copper 0 to 11%, manganese 0 to 5%, silicon 0.3 to 4.6%, sometimes 1% molybdenum and 0.25% titanium It is an alloy which was added and formed. In the alloy of the nichrome brand, nickel chromium (Nichrome I) contains 60% nickel, 25% iron, 11% chromium, and 2% manganese. Nichrome II (75% nickel, 22% iron, Nickel chromium II is a heat resistant alloy containing 11% chromium and 2% magnesium and containing 85% nickel and 15% chromium. / 380,718 and US Pat. No. 5,388,594 or alloys with similar properties.

As shown in FIG. 12, the heater blades 121 are arranged to extend symmetrically from the hub 111. Otherwise, they may be arranged without symmetry. That is, for example, six or eight heater blades 121 can be divided into two groups of three or four, for example. As described above, the heater blades 121 in these two groups are separated by a predetermined gap 131. In addition, as shown in FIG. 19, in which the plurality of heater blades 121 are unfolded without being rolled into a cylindrical shape, the groups are separated by a wider gap 133.

The size of this wide gap 133 is set so that the conduction of heat from adjacent heater blades 121 of the adjacent group to the portion of the cigarette 23 placed below the gap 133, in particular the transfer of radiant heat, is minimized. Thus, the gap 133 is able to maintain a stronger state than the unheated portion of the cigarette 23 placed under the narrow gap 131, the portion of the unheated cigarette 23 placed thereunder. 23) Increase the strength to maintain the circumferential shape, so that it is easy to remove the weakened cigarette portion after smoking. If necessary, one or more of the heaters arranged symmetrically or asymmetrically may be heated at the same time.

The heater blade 121, which is a heating element used in the present invention, has two corner portions 116A and 116B separated by the gap 125, so that a much larger amount than the amount produced by the heating element is made. You will be able to create aerosols. The tubular heater blade has a good performance of transferring heat to the cigarette, but in particular, if the sealed state of the smoking device housing is formed in the outer surface of the housing to form a hole for exchanging air with the outer surface of the housing, The aerosol may be deteriorated by the heating element through which the air in the outside of the cigarette passes through the optimum transport into the inside of the cigarette.

In addition, the heater according to the present invention has the same volume as the heater blades passed through, but because of the large surface area, the chance of accommodating aerosols along the flow of air, such as by the gap 125, the heater blades 121 accordingly The release of the flavor per unit of energy by the will increase. As described above, the gap 125 between the corners 116A, 116B is defined to have a size that maximizes the radiation of heat in a given heater blade 121 geometry. Since the heater blade 121 is configured as described above, the amount of generation of aerosols increases, so that the total volume of the heater blade required to produce the same amount of flavor can be reduced, and as a result, the cigarette 23 and the heater inserted from the lighter In addition to the energy required to properly heat the blade 11, a power source such as a battery may be reduced, thereby reducing the weight of the lighter.

An example of the gap 125 is not particularly limited, and the width of the gap 125 may be about 0.020 in ± 0.005 in, and each of the portions 116A and 116B has a width of about 0.0125 to 0.017 in and a length of about 0.55. in ± 0.005 in, thickness of about 0.008 to 0.010 in, and the length from the end of the hub 111 to the distal end of the connecting portion 118 may be about 1.062 ± 0.0625 in.

It has been found that the generation of aerosols is better than allowing the inhaled air to cross or radially insert the inserted cigarette 23 when smoking, in order to flow in the longitudinal direction of the cigarette. The gaps 125, 127, and 131 form passages through which air is sucked into the inserted cigarettes. In addition to these gaps, additional air passages may be formed by drilling holes in the heater blades to optimize air distribution.

As another example of the heater blade used in the present invention, as shown in FIG. 16, the first corner portion 116A and the second corner portion 116B of the heater blade form a waveform. Here, the waveforms of the respective sections 116A and 116B are parallel to each other and are spaced apart from each other at a slight interval, and the gap 125 between these sections 116A and 116B also forms a waveform. Such waveforms can increase the surface area of the heater blades and increase the generation and movement of aerosols. Such corrugated heater blades are described in detail in EP-A-0,615,411, US Patent Application Nos. 08 / 380,718 and 5,388,718.

Next, a method of manufacturing a heater blade will be described with reference to FIGS. 18 and 19. Here, the division of the production stage may be any order in order to achieve rapid production and material saving.

Using a sheet or strip of about 2 to 20 mils thick with a suitable material, for example about 10 mils thick, the first corner 116A is roughly mediated through the first end 115. A plurality of heater blades 121 are formed so as to be integrally connected to the straight portion 111A in a right angle to be comb-shaped. The plurality of heater blades 121 are parallel to each other with a gap 131 formed between the second corner portion 116B of one heater blade and the edges facing each other of the first corner portion 116A of the adjacent blade. It is arranged to be. As described above, the plurality of heater blades 121 are arranged in a symmetrical arrangement, or a plurality of heater blades 121 in a state divided into a gap 131 of the same width as shown in FIG. As shown in 19, each heater blade 121 is separated into the same narrow width of the gap 131, and any one of these heater blades and the neighboring heater blades are separated into a large gap 133, Each is divided into two groups 121A and 121B having a predetermined width X so as to be asymmetrically arranged. Here, the straight portion 111A is at least 1/2 of 1.5 times the width X of the group so that, on the other side, when the heater blade is rolled, one more wide gap 133 is formed on the other side. An end having a length is formed. The sum of these two ends should be longer than the width X of the heater blade groups 121A and 121B so that they can overlap when these ends are connected. For example, but not limited to, the gap 131 between the heater blades 121 should be about 0.040 ± 0.005 in width despite the symmetrical asymmetrical arrangement, and in the example of the asymmetrical arrangement, the heater blade group 121A, The gap 133 between 121B) should be about 0.125 ± 0.005 in wide.

The heater blade 121 is composed of a connecting portion 118 and two corners 116A, 116B as described above.

Forming a sheet or strip of suitable material in the form described above is carried out by the conventional technique of cutting with a CO ₂ laser or Yag 1azer while the sheet or the like is pressed. If the strip is used as a processing material, the number of heater blades 121 formed in the strip may exceed the number of heater blades required to make one cylindrical heater blade assembly. If necessary, the strip in a straight state is cut so that a straight portion 111A is formed so that a predetermined number of heater blades extend therefrom. Then, if the stepped contact portions 122A, 122B, 122C are used, they are formed by a stamping method.

If it can be adopted, the ceramic coating 300 for shielding the place formed by crimping is implemented, and, for example, the straight portion 11A or the end portion 115 of the heater blade 121, the second end portion 122 or the entire heater blade. B) Thermally spray on a portion of it to achieve the desired form described above. The ceramic coating is performed after the step of rolling the heater blade assembly in the manufacturing process as described above, if necessary, may be carried out before forming the heater blade. As is known, the above shielding process is performed before each step of fabricating the heater and applying the ceramic is performed to determine a portion to which the ceramic is to be applied.

The straight portion 111A is rolled to form a circular hub 111, in which case the straight portion 111A may be rolled in either direction. The straight portion 111A is rolled so that the anode contact portion 122c at the second end 122 of the heater blade 121 is simply connected with the pin 104B on the outer surface of the cylindrical heater opposite the cigarette, for example, It will not be damaged when inserted and removed. The curled portion is rolled to a diameter smaller than the maximum diameter required to be inserted into the structure, after which the curled portion is extended to take the form of being connected to the electrical connection member. Instead, the curled portion may be joined by a welding technique such as spot welding or laser welding to form the hub 111.

Meanwhile, as shown in FIG. 13, each heater blade 121 is slightly bent to form a bias state, so that when the heater blade assembly is made, the portions 116A and 116B and the connecting end 118A are inserted. It is designed to press down old cigarettes. The bias state as described above is preferably formed before winding the heater blade, but may be formed after being dried. This bias state increases the thermal contact between the heater blade and the inserted cigarette to increase the thermoelectric efficiency (熱 傅 效 率).

The thermoelectric efficiency can also be increased by optimizing the surface area of each portion 116A, 116B which will have a substantial heat exchange relationship with the underlying cigarette. As shown in FIG. 17A for the convenience of showing the first corner portion 116A, the lower surface 117 of the corner portions 116A and 116B is flat as the corner portions are flattened in the transverse direction in the above-described example. Meanwhile, in order to increase the thermoelectric efficiency, the lower surface 117 of the corner portion 116A may be formed in various shapes that are not flat as shown in FIGS. 17B and 17C, that is, it does not need to be bulky. In addition, the lower surface 117 of the corner portion 116A is angled or curved to form a much wider area so that the current density is not lowered and the heating of the corner portion is not necessary.

Here, the lower surface 117 of the corner portion 116A in the form as described above, so that any part of the cigarette 23 in the process of inserting, removing or correcting the position of the cigarette 23 is not to be weakened or torn do. That is, the lower surface 117 of the corner portion 116A is in contact with the cigarette 23 or thermally close to the cigarette 23 at its midpoint or vertex, and the rest of the portion 116A and the radiant heat. Have a thermoelectric relationship.

The shape of the lower surface 117 of the corner portion 116A is formed by compression molding the corner portions 116A and 116B of the heater blade 121 without the heater blade 121 curling. This compression molding occurs at the same time as the compression molding described above when the biasing state is achieved. This compression molding to form the bottom surface also increases the strength of the corners 116A and 116B so that unwanted shorts and deformations can be avoided.

Next, a second method of manufacturing the heater blade assembly will be described. First, a tube made of a suitable material is prepared, and a heater blade 121 is formed using a technique such as laser cutting. Instead, it adopts a swaging technigue, inserts an internal mandrel into the tube to form the heater blade profile described earlier, and then installs another swage on either the inside or outside. Cut to make the profile. If necessary, the ceramic coating described above is applied to the tube cut into the profile as described above.

The present invention also makes it possible to minimize the stress potentially caused by heat. That is, since the heater blade 121 and the hub 111 is integrated, it is possible to eliminate the stress caused by the portions where the heating elements are separately separated from each other.

The various embodiments of the present invention described above are all designed to effectively release tobacco-flavored aerosols to smokers under normal handling conditions. In particular, it was found that 5 to 13 mg, preferably 7 to 10 mg of aerosols were released to smokers during 8 times of smoking crops which inhaled 35 ml while inhaling for 2 seconds.
