Description

  The present invention relates to a pseudo-cigarette that generates heat by a chemical reaction.

  In general, cigarettes are being restricted from smoking in public places such as airplanes due to various circumstances in recent years. For this reason, there has been proposed a pseudo-cigarette similar to general tobacco that can be sucked without being restricted by a place (for example, Patent Document 1). The pseudo-cigarette described in Patent Document 1 can taste the flavor of ordinary tobacco without burning the tobacco. As an example of this pseudo-cigarette, a heating element such as a nichrome wire, a flavor generating medium, and a power source are incorporated, and the heating element is heated by power supply from the power source so that a flavor component can be generated and sucked. Has been.

  Moreover, even if the shape is similar to tobacco, there are also known things that suck in the scent of herbs, fruits, etc., and here, such things are also referred to as “pseudo tobacco”.

  Patent Document 1 also describes a power source that is not provided in the pseudo-cigarette itself but provided in an external device. A heating device containing a power source is shown as the external device. In order to supply electric power to the pseudo-cigarette from an external device, the pseudo-cigarette using this device is provided with an electrode of a connector connected to the device. By energizing the pseudo-cigarette from an external device through this electrode, the heating element of the pseudo-cigarette is heated to generate a flavor.

  Patent Document 1 also shows a heating element on the apparatus side as still another example. In this type of pseudo-cigarette, the flavor generating medium is heated by the heating element of the apparatus, and the generated flavor is sucked through the filter.

Further, as a method of generating heat when sucking tobacco, a method using a chemical reaction is also known (Patent Document 2). The cigarette holder using this chemical reaction has a space for storing cigarettes and two types of liquids separated by a partition around the space. In use, the cigarette holder is bent to break the partition wall, thereby mixing the two liquids to cause a chemical reaction to generate heat. And, by this heat generation, the tobacco inserted in the tobacco holder is heated and the nicotine component is sucked.

Hereinafter, a preferred embodiment of the pseudo-cigarette of the present invention will be described with reference to FIGS. FIG. 1 shows a pseudo-cigarette 1 according to a first embodiment of the present invention, FIG. 1 (a) is a plan view, and FIG. 1 (b) is a cross-sectional view taken along line 1b-1b of FIG. 1 (a). is there. FIG. 2 is an exploded perspective view showing the pseudo cigarette 1 of FIG. 1 in an exploded manner. 3 is an enlarged perspective view of the reaction tube, and FIG. 4 is a partially enlarged sectional view of a portion indicated by A in FIG. The pseudo cigarette 1 is a disposable type.
As shown in FIGS. 1 and 2, the pseudo-cigarette 1 has a tubular outer cylinder (tubular body) 2 having a length and a diameter that are substantially the same as those of ordinary tobacco. This outer cylinder 2 is formed from synthetic resins, such as a polycarbonate, for example. Four rectangular small holes 4 are formed along the circumference at the approximate center in the longitudinal direction of the pipe-shaped outer cylinder 2. These small holes 4 serve as air intakes when the simulated cigarette 1 is sucked. The shape of the small hole 4 does not need to be rectangular, and may be circular or elliptical. The number of small holes 4 is not limited to four, and may be three or less or five or more depending on the shape and size of the small holes 4.

  A filter 6 is attached to one end of the outer cylinder 2 in the outer cylinder 2. The filter 6 contains a flavoring agent such as fruit, peppermint, and nicotine as an additive 6a in a state in which the liquid is impregnated or crystallized. In the outer cylinder 2, a cylindrical heat storage body 8 is disposed adjacent to the filter 6. A through hole 8 a is formed in the center of the heat storage body 8 coaxially with the axis of the heat storage body 8. The diameter of the heat storage body 8 is dimensioned so that a gap is formed between the inner surface of the outer cylinder 2 and the outer surface of the heat storage body 8. A plurality of grooves extending along the axial direction of the heat storage body 8 and spaced apart at a predetermined interval along the circumferential direction of the heat storage body 8 may be provided on the outer surface of the heat storage body 8. These gaps and grooves serve as air flow paths when the user sucks the pseudo-cigarette 1. The heat storage body 8 is comprised from the metal single-piece | unit or the composite material of several materials, for example.

  A reaction cylinder 10 is further disposed in the outer cylinder 2 adjacent to the heat storage body 8. As shown in an enlarged view in FIG. 3, the reaction cylinder 10 has a substantially cylindrical main body 10a with one end open, and a column 10b that protrudes integrally in the axial direction of the reaction cylinder 10 at the center of the main body 10a. The reaction cylinder 10 is made of a material having good thermal conductivity such as copper or aluminum. The column 10 b of the reaction cylinder 10 is inserted in close contact with the through-hole 8 a of the heat storage body 8, and is arranged so that the shoulder 10 c is in close contact with the end surface of the heat storage body 8. The outer shape of the reaction tube 10 on the side of the opening 10d is a large-diameter portion 10e whose diameter is accommodated in the outer tube 2. A slight gap G is formed between the large diameter portion 10e and the outer cylinder 2 (FIG. 4). A portion of the main body 10a extending from the large diameter portion 10e to the shoulder portion 10c is a reduced diameter portion 10f having a diameter slightly smaller than that of the large diameter portion 10e. Grooves 10g extending along the longitudinal direction of the reaction tube 10 and spaced apart at a predetermined interval along the outer periphery of the reaction tube 10 are formed on the outer surface of the reduced diameter portion 10f. These grooves 10g are formed over the entire length of the reduced diameter portion 10f and communicate with the small hole 4 of the outer cylinder 2 on the large diameter portion 10e side (FIG. 1 (b)).

  On the other hand, an annular groove 10h is formed on the outer periphery of the large-diameter portion 10e, and an O-ring (seal member) 11 is disposed therein (FIGS. 2 and 4). FIG. 4 shows a state in which the space between the reaction cylinder 10 and the outer cylinder 2 is sealed by the O-ring 11. Further, as best shown in FIG. 3, the reaction cylinder 10 has a notch 10k provided on the end surface 10j of the large-diameter portion 10e at predetermined intervals along the circumferential direction of the large-diameter portion 10e, and the notch 10k. A communicating groove 10 n is formed in the vicinity of the opening 10 d on the inner surface of the reaction tube 10. The groove 10 n extends linearly along the longitudinal direction of the reaction tube 10.

  In addition to the reaction cylinder 10, a liquid tank 14 is further installed in the outer cylinder 2. The liquid tank 14 has a hollow and substantially cylindrical shape, and includes a fitting portion 14 a attached to the opening 10 d of the reaction tube 10 and a main body 14 b having a length reaching the other end of the pseudo-cigarette 1. The main body 14b is formed to have a slightly larger diameter than the fitting portion 14a. A circular hole 14c is formed at the center of the fitting portion 14a, and an opening 14d is formed at the other end of the liquid tank 14. Normally, the circular hole 14c is sealed with a material that is easily broken when subjected to pressure, such as a thin aluminum foil 14e. This sealing material may be a rubber having similar properties or a viscous grease. The liquid 16 is held in a cavity 14g of the main body 14b in a state of being sealed by a piston, that is, a plug 14f. This liquid 16 is, for example, water. The plug 14f is made of, for example, a material such as NBR (nitrile butadiene rubber), and is closely attached to the inside of the cavity 14g so as to be movable in the left-right direction in FIG. 1B. Further, grooves 14h that extend linearly over the entire length of the main body 14b are formed on the outer surface of the main body 14b of the liquid tank 14 at predetermined intervals along the outer periphery of the main body 14b.

Next, a method for using the pseudo cigarette 1 configured as described above will be described. Referring to FIG. 1, when the stopper 14f is pressed with, for example, a thin bar as indicated by an arrow 18, the pressure of the liquid 16 increases and the aluminum foil 14e is ruptured. As a result, the liquid 16 is injected into the reactant 12 in the reaction tube 10 from the circular hole 14c. Then, the reactant 12 generates a heat by causing a chemical reaction with the liquid 16. The chemical reaction formula at this time is expressed as follows.
Ca0 + H ₂ O → Ca (OH) ₂ +15.6 Kcal / mol
That is, 56 g of calcium oxide (quick lime) and 18 g of water react to generate 15.6 Kcal heat and calcium hydroxide (slaked lime). In the case of the first embodiment, for example, the amounts of calcium oxide and water can be determined so that heat of 0.139 Kcal is generated by the reaction of 0.5 g of calcium oxide and 0.16 g of water.

  This heat propagates from the shoulder 10 c and the column 10 b of the reaction cylinder 10 in contact with the heat storage body 8 to the heat storage body 8. Since the pillar 10b propagates heat from the inside of the heat storage body 8 to the heat storage body 8, it can conduct heat efficiently in a short time. Therefore, the waiting time of the user, that is, the aspirator (not shown) can be reduced. Thereby, when the heat storage body 8 reaches a predetermined temperature, that is, about 40 ° C. to 43.5 ° C., a state suitable for suction is obtained. When the suction person attaches a mouth to the filter 6 and sucks, air flows from the small hole 4 as described above. This air passes through the gap or groove 10g between the reduced diameter portion 10f of the reaction cylinder 10 and the outer cylinder 2, and further passes through the gap between the heat storage body 8 and the outer cylinder 2. And the air heated when passing through the reaction cylinder 10 and the heat accumulator 8 reaches the filter 6. The additive 6a contained in the filter 6 is heated and evaporated by the heated air, and the suction person can obtain a desired flavor by suctioning with the air. At that time, smoke does not occur because there is no member that burns like ordinary cigarettes. Moreover, since the heat storage body 8 can dissipate heat for a predetermined time and continue to supply heat to the sucked air, it can enjoy sucking in the same way as ordinary cigarettes.

  When the reactant 12 that is quicklime reacts with the liquid 16 that is water, relatively high-temperature water vapor is generated in the reaction tube 10. The generated water vapor enters the gap G (FIG. 4) between the reaction tube 10 and the outer tube 2 through the aforementioned groove 10n and the notch 10k of the reaction tube 10. However, since the O-ring 11 is arranged in the large diameter portion 10e of the reaction cylinder 10 as shown in FIG. 4, this water vapor does not move toward the small hole 4 but is sucked by the user. That is blocked. This water vapor is discharged from the other end of the pseudo-cigarette 1, that is, the end opposite to the filter 6, through the aforementioned groove 14 h (FIG. 2) provided on the outer surface of the liquid tank 14. Thus, since water vapor | steam is discharged | emitted without sealing in the outer cylinder 2, the outer cylinder 2 does not burst or the components in the outer cylinder 2 do not protrude outside the outer cylinder 2. Moreover, since water vapor | steam is discharged | emitted far from a user, there is also no possibility that a user will attract | suck this water vapor | steam. Moreover, since the pseudo-cigarette 1 of the first embodiment does not contain harmful substances, it does not give a load to the environment even if it is discarded after use.

  Next, a pseudo cigarette 50 according to a second embodiment of the present invention will be described with reference to FIG. FIG. 5 shows a simulated cigarette 50 according to the second embodiment of the present invention, FIG. 5 (a) is a plan view, and FIG. 5 (b) is a cross-sectional view taken along line 5b-5b of FIG. 5 (a). is there. In the description, the same components as in the first embodiment, that is, the outer cylinder 2, the filter 6, the heat storage body 8, and the reaction cylinder 10 will be described with the same reference numerals. The second embodiment is different from the first embodiment in that the reactant 62 and the liquid 66 in the reaction cylinder 10 are integrated as a cartridge 70. The pseudo-cigarette 50 of the second embodiment can be reused by replacing the cartridge 70 and the filter 6 after use. Hereinafter, the cartridge 70 will be mainly described. The cartridge 70 includes a front end tube 72 that is inserted into and closely attached to the reaction tube 10 and a liquid tank 74 that is attached to the opening 72 a of the front end tube 72. The tip tube 72 has a substantially cylindrical shape and is made of a material having good thermal conductivity. A reaction agent 62 is disposed inside the tip tube 72.

On the other hand, the liquid tank 74 includes a cap 76 attached to the opening 72 a of the distal end cylinder 72 and a liquid storage portion 78 attached to the opening 76 a of the cap 76. The cap 76 has an injection tube 76c that extends outwardly through the tip 76b at the tip 76b. The tip of the injection tube 76c is located inside the reaction agent 62, and the liquid 66 injected from the injection tube 76c can be reacted with the reaction agent 62 effectively and quickly. A liquid storage part 78 is attached to the opening 76 a of the cap 76. The liquid storage part 78 includes a fitting part 78a attached to the cap 76, and a main body 78c extending from the fitting part 78a to the other end side of the simulated cigarette 50 through the step part 8b. A flange 78d is formed at the end of the main body 78c along the outer periphery of the main body 78c. When the cartridge 70 is inserted into the reaction cylinder 10, the flange 78d comes into contact with the end 2a of the outer cylinder 2, It can be confirmed that the attachment of the cartridge 70 is completed. A plug 78 f is arranged in the liquid storage part 78 to contain the liquid 66 in the liquid storage part 78. A circular hole 78e is formed in the end surface of the fitting part 78a of the liquid storage part 78. The end face is similar to the first embodiment, for example, an aluminum foil 78g is stuck and a circular hole 78e is sealed. Press toward. By this operation, the aluminum foil 78g is ruptured, and the liquid 66 is injected into the reactant 62 from the injection tube 76c. The reactant 62 generates heat by a chemical reaction with the liquid 66 as in the first embodiment. This heat is transmitted to the heat storage body 8 through the reaction cylinder 10. Then, when the heat storage body 8 reaches a desired temperature, the suction person can suck air from the filter 6. By suction, air flows from the small holes 4 as in the first embodiment, and is heated while passing through the reaction tube 10 and the heat storage body 8 to evaporate the additive 6a in the filter 6. Thereby, the aspirator can taste a desired flavor. The aforementioned injection tube 76c injects the liquid 66 into the reaction agent 62, so that the liquid 66 and the reaction agent 62 are allowed to react quickly to shorten the waiting time until a predetermined temperature is reached. can do.

  In order to replace the cartridge 70 after use, a new cartridge 70 may be mounted by simply pulling out the flange 78d with a finger and pulling it out. The filter 6 may be pulled out from the outer cylinder 2 and another filter 6 may be attached. Thus, the cartridge 70 and the filter 6 can be easily replaced. By this replacement, the pseudo-cigarette 50 can be used a plurality of times, and the pseudo-cigarette 50 can be reduced in cost. Moreover, if the filter 6 is replaced with one containing the desired additive 6a, the desired flavor can be enjoyed.

  In the pseudo-cigarette 50 of the second embodiment, the configuration for discharging water vapor to the outside, such as the O-ring 11 and the groove 14h of the liquid tank 14 described in the pseudo-cigarette 1 of the first embodiment, is as follows. The illustration is omitted.

  As described above in detail with respect to the preferred embodiment of the present invention, quick lime and water can react with each other in a small amount and generate desired heat, so that the simulated cigarettes 1 and 50 can be reduced in weight. As with normal cigarettes, it can be sucked in easily. In addition, since the cost itself is low, the disposable type and the type that can be exchanged and reused can be made inexpensive.

  Further, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications and changes are possible. For example, the groove 10g of the reaction cylinder 10 does not need to be linear along the axial direction of the reaction cylinder 10, and may be spiral. Further, in order to further facilitate the replacement of the filter 6, the filter 6 may be partially pushed into the outer cylinder 2. In this case, after use, the portion of the filter protruding from the outer cylinder 2 can be easily picked and discarded.

  In the above embodiment, the combination of quicklime and water has been described, but other combinations such as a combination of iron and air (oxygen) and the like that generate heat when mixed with each other are considered. It is done.
