Tobacco leaf installation method for heated cigarettes

Abstract

In a smoking fixture with a port-type heating method, tobacco is put in and smoked, and then the tobacco after smoking is simply taken out in the ash by a simple action of ejecting the cigarette butt. In a smoking fixture with a needle-type heating method heated by a plate-shaped or needle-shaped heater, tobacco after smoking cannot be simply taken out in the ash. Thus, a portion of the tobacco insertion tube is cut, and pellet-shaped tobacco is put in the cut portion, and then the cigarette holder and the tobacco insertion tube are pulled out from the smoking fixture together, and the tobacco after smoking is directly thrown into the ash from the cut portion.

Description

Technical Field

[0001] The present invention relates to a method for installing tobacco leaves, wherein tobacco leaves (heated cigarettes or cigarettes smoked by ignition or cigarettes or cigars rolled only by hand) are inserted into a smoking jig, the inserted tobacco leaves are heated by a heater, and nicotine or tobacco flavor evaporated from the tobacco leaves is inhaled through the smoking jig. Background Art

[0002] Generally speaking, a smoking fixture called a vaporizer is a device that puts tobacco leaves into a heating cylinder, installs an inhalation port (mouthpiece) called a dripper, and inhales nicotine or smoke generated by the heating of the tobacco leaves through the dripper. Compared with heated cigarettes or ignited cigarettes such as IQOS electronic cigarettes (IQOS) / glo electronic cigarettes (glo) / Ploom S electronic cigarettes (Ploom S), the cost of smoking is low, and it is a very popular product. There are two ways to heat the inserted tobacco leaves: a port-type heating method in which tobacco leaves are placed in a port and heated by a heater from the outside of the port, and a needle-type heating method in which a plate-shaped or needle-shaped heater is applied to the center of the inserted tobacco leaves to heat them. The port-type heating method requires insulating material on the periphery of the heater to prevent high power consumption and the outside of the fixture from becoming hot, so the fixture is larger.

[0003] In addition, the needle-type heating method consumes less power because the inserted tobacco leaves are heated from the center. Even if no insulating material is installed, the outside of the clamp is not particularly hot. Therefore, the rechargeable battery used for driving is small, and most of the clamps are small.

[0004] However, the steam electronic cigarette using the needle-type heating method has the disadvantage that the tobacco leaves cannot be easily taken out after smoking. Most steam electronic cigarettes are port-type heating clamps, that is, after smoking, the drip tip can be removed and the tobacco leaves can be easily taken out by knocking the clamp. Or in the case where the tobacco leaves are placed in a metal tube (generally called a spacer) and placed in the port for smoking, the spacer (tobacco leaves) can be taken out more easily. Generally, the so-called action of "discharging the cigarette butt" is performed and it is easily taken out. In addition, the steam electronic cigarette with the needle-type heating method has the heater inserted almost to the center of the inserted tobacco leaves, so that the friction between the heater and the tobacco leaves is achieved, and the tobacco leaves will not fall out of the clamp even if the clamp is directly knocked. As a result, the power consumption is low and the clamp is miniaturized, but the steam electronic cigarette with the needle-type heating method has hardly been commercialized in this way.

[0009] Technical problem to be solved by the invention

[0010] The present invention provides an improved steam electronic cigarette, which develops and commercializes the smoking clamps described in Patent Documents 1 and 2, but it is also impossible for users to "discharge cigarette butts", which has received comments that it is not feasible. Therefore, in this patent, a needle-shaped heating smoking clamp is provided that enables "discharging cigarette butts". BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 311: Tobacco leaf introduction tube DETAILED DESCRIPTION

[0017] Figure 3 The axial cross-sectional view of the smokeless smoking fixture disclosed in FIG7 inserted in patent document 1 includes: a spring 203, which serves to press the atomizer 94 to the heating cylinder; a 510 interface 220, which supplies power to the atomizer 94; the atomizer 94; a bushing (changed to silicone with holes in patent document 2) 230, which is located between the atomizer 94 and the heating cylinder; an inner tube 5, which constitutes the heating cylinder; an O-ring 400; a connector 202; a cigarette holder B95; a mouthpiece 310; and a tobacco leaf introduction tube 311.

[0018] The sprayer 94 includes: a container 204 for placing liquid; an inner tube 206; a hole 207 for supplying liquid to a heater; a heater 205; an air inlet 209; and an interface 510. Since the details are described in Patent Document 1 or Patent Document 2, the description is omitted here. Figure 4This is an axial cross-sectional view of a mouthpiece 310 and a tobacco introduction tube 311 disclosed in FIG5 in Patent Document 1. The front end 312 of the tobacco introduction tube 311 is manufactured according to the tobacco introduction tube drawing, and a washer or bush made of a metal material or a heat-resistant resin material is inserted. In short, a hole 313 for the heater to pass through is manufactured almost at the center.

[0019] The smoker loads tobacco into the tobacco introduction tube 311 and installs the cigarette holder. Figure 3 As shown in the display, the tobacco is inserted into the smoking fixture. By inserting the heater 131, the heater 131 is inserted into the center of the inserted tobacco (not shown), and the tobacco is effectively heated. After smoking, the tobacco introduction tube with the cigarette holder is pulled out of the smoking fixture, the cigarette holder is removed, and the tobacco inside is destroyed after the smoking is finished. At this time, the tobacco introduction tube becomes hot due to heating, and thus, the user is not able to remove the cigarette holder until it becomes cold.

[0020] Therefore, the inventors, in order to improve the inconvenience, Figure 1 and Figure 2 As shown in the figure, a notch 314 is provided in a part of the tobacco introduction pipe 311. Figure 1The appearance diagram is used for further specific description. The tobacco leaf introduction tube 311 has a thickness of 0.1 mm to 0.5 mm and an inner diameter of about 7.7 mm Φ to 9.0 mm Φ. Any size is acceptable, but in order to cooperate with the drip nozzle used as the mouthpiece 310, 8.9 ± 0.1 mm Φ is required. The actual size uses an AL tube with a thickness of 0.25 mm and an inner diameter of 8.9 mm Φ. The front end 312 is processed by drawing. For this drawing process, it is known that a pipe cutter with a rotating blade is used, and the thickness of the AL tube is also thin by cutting with a blade that makes the blade slightly blunt. During transportation, the drawing is formed inward and cut. It is known that using this method to cut by drawing inward, a circular spacer or sleeve of a metal material or a heat-resistant resin material having the same Φ as the inner diameter of the AL tube is inserted from the mouthpiece side and pushed inward, thereby fixing it to the front end 312. Alternatively, it can be manufactured even by drawing the front end of the AL tube. In the tobacco introduction tube 311 manufactured in this way, as shown in the figure, a cutout portion 314 with a length of 10 mm to 15 mm or more of half a circumference is manufactured using a laser or a grinder. The tobacco introduction tube 311 having the front end portion 312 and the cutout portion 314 is inserted into the mouthpiece 310. A tobacco transfer spacer or a cylindrical pellet formed by cutting cigarettes or compressing tobacco, as shown in 315, is placed in the cutout portion 314, and a smoking fixture is inserted through the cigarette holding portion B 95, and the cigarette is heated by the heater 131 and smoked. After smoking, the tobacco introduction tube 311 and the mouthpiece 310 are taken out together, and the various tobaccos shown as 315 are directly discarded in the ashes. At this time, the heated tobacco introduction tube 311 cannot be touched by hand, and no burns will occur.

[0021] Cylindrical tobacco leaves are inserted in this patent, but the shape of the tobacco leaves can be any shape and is not limited by the shape.

[0022] Industrial Applicability

[0023] In a needle-shaped heating smoking fixture that is heated by a plate-shaped or needle-shaped heater, after tobacco leaves are placed in the smoking fixture and smoked, the tobacco leaves after smoking can be simply taken out in the ashes. That is, a portion of the tobacco introduction tube for placing tobacco leaves is cut, and granular tobacco leaves are placed in the cut portion, and the smoking fixture is inserted in a state of being integrated with the cigarette holder to smoke. After smoking, the cigarette holder and the tobacco introduction tube are pulled out together, and the tobacco leaves after smoking can be directly thrown into the ashes from the cut portion, so that even a needle-shaped heating smoking fixture can discharge cigarette butts.
