Hereinafter, configurations and applications according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE INVENTION The following description is one of many aspects of the claimed invention and the following description forms part of a detailed description of the present invention.

In the following description, well-known functions or constructions are not described in detail for the sake of clarity and conciseness.

FIG. 1 is a view schematically showing the construction of a smokeless cigarette according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a graph comparing the amounts of nicotine transfer of paper filters and acetate filters .

As shown therein, the lead-free cigarette 100 according to an embodiment of the present invention includes a body 110 having an outer appearance and containing a raw material medium 102, A capsule filter 120, a tube filter 130 penetratingly coupled to an outer surface of the mouth part 110 and a blocking cap 150 blocking an opening formed at both ends of the body part 110 .

First, the body part 110 of the present embodiment may include a mouthpiece part 111 and a cartridge part 115 in which a raw material medium 102 is provided in an internal space.

The body part 110 has a hollow cylindrical shape with both ends thereof opened, and the mouthpiece part 111 and the cartridge part 115 are integrally connected to each other. However, as shown in FIGS. 1 and 2, the mouthpiece portion 111 and the cartridge portion 115 may have a stepped shape by having mutually different inner diameters and outer diameters. The mouthpiece portion 111 improves the assembling property of the tube filter 130 by structurally supporting the tube filter 130, and improves the sealing effect by firmly fixing the incision preventing cap 150.

The tube filter 130 has a hollow cylindrical shape and is connected to the mouthpiece portion 111 so as to surround the outer surface of the mouthpiece portion 111. The tube filter 130 may be made of a flexible material. Accordingly, the sense of heterogeneity felt when the user smokes the smokeless cigarette 100 of the present embodiment is minimized. For example, the tube filter 130 can be made of acetate tow or silicone used in common tobacco, thereby reducing the sense of heterogeneity.

The inner diameter of the tube filter 130 corresponds to the outer diameter of the mouthpiece portion 111 and the outer diameter of the tube filter 130 corresponds to the outer diameter of the cartridge portion 115. Therefore, the overall shape of the body part 110 coupled with the tube filter 130 has a long cylindrical shape such as a general cigarette, and may be included as one cigarette in the suction device, as will be described later.

1, the paper filter 140 may be provided at the innermost portion of the cartridge portion 115 of the present embodiment, that is, at the portion where the mouthpiece portion 111 and the cartridge portion 115 meet. By incorporating the paper filter 140, it is possible to minimize the problem that the migration efficiency of nicotine is lowered, and thus the sense of fullness of smoking can be maintained.

Referring to FIG. 3, it can be seen that in the case of a commonly used acetate filter, the amount of transfer of nicotine is about 3 times higher than that of the paper filter 140 of the present embodiment.

In the cartridge part 115 of the present embodiment, the raw material medium 102 is accommodated, the capsule filter 120 is embedded in the end part, and the raw material medium 102 is filled in the inside space of the cartridge part 115. The capsule filter 120 is crushed by the user's pushing operation and the user's smoking satisfaction can be improved through the fragrance generated from the crushed capsule filter 120.

Here, when the raw material medium 102 has a flavor A and the capsule filter 120 has a flavor B, the capsule filter 120 may be blown by using a smokeless cigarette 100 that gives flavor A, and a B taste can be felt. Or when the flavor intensity is lowered due to the continuous use of the smokeless cigarette (100), the capsule filter (120) may be blown to increase the taste strength.

The packing rate (volume) of the raw material medium 102 filled in the internal space of the cartridge part 115 may be in the range of 33 to 66%. When the raw material medium 102 is filled within this range, the flow of the raw material medium 102 can be smoothly induced when the user sucks the raw material medium 102. In addition, the flavor ingredient can be smoothly transferred.

4 is a graph showing the amount of transfer of nicotine and the suction resistance according to the filling ratio of the raw material in the cartridge portion.

As shown in the figure, when the suction resistance of the smokeless cigarette 100 is measured according to the filling rate of the raw material medium 102, when the raw material filling rate is about 2/3 (66%) or less, (66%), the suction resistance tends to increase. If the flow space of the raw material medium 102 is maintained at a certain level, the packed raw material medium 102 hardly affects the suction resistance. However, since the flowable space of the raw material medium 102 is reduced, It can be understood that the suction resistance is increased while the fluid 102 does not smoothly flow.

Similarly, when the amount of nicotine migration in the smokeless cigarette 100 according to the raw material filling rate is measured, when the raw material filling rate is 2/3 (66%) or less, the amount of nicotine transfer increases proportionally with the amount of raw material, Did not increase. Therefore, it is important to ensure a space for the flow of the raw material medium 102 in the cartridge part 115, so that the cartridge part 115 can induce smooth flow of the raw material medium 102 upon inhalation and promote efficient transfer of nicotine 115) space is preferably between about 1/3 (33%) and 2/3 (66%).

Meanwhile, FIG. 5 shows that the non-burning condition of the smokeless cigarette 100 is uniformly maintained up to 100 puff or more.

The smokeless cigarette 100 of this embodiment can be combined with the shutoff cap 150 at both ends of the body part 110 as shown in Figs. 1 and 2 to prevent the incoherent loss of the raw material medium 102 . The smell of the raw material medium 102 or the capsule filter 120 in the body 110 can be blocked by the blocking cap 150 so that the smokeless cigarette 100 is constructed together with the normal cigarette, You can also make instruments. In addition, since the detachable structure of the shutoff cap 150 prevents the loss of flavor components, the suction feeling can be maintained and reused.

Fig. 6 is a view showing a configuration of a suction mechanism according to an embodiment of the present invention. The suction mechanism 1 includes a cigarette case 10, a smokeless cigarette 100 provided inside the cigarette case 10, ). In this embodiment, the suction device 1 may be composed of 19 general cigarettes 100a and one smokeless cigarette 100 in a 19 + 1 configuration. However, the present invention is not limited thereto. For example, it can be a 18 + 2 configuration or a 17 + 1 configuration. Or a 20 + 2 configuration, consisting of 20 regular cigarettes and 2 smokeless cigarettes. In this case, 20 general cigarettes may be inserted in the cigarette case and two smokeless cigarettes may be attached to the outside of the cigarette case.

The smokeless cigarette 100 and the cigarette 100a may be mixed with each other because the cutoff cap 150 provided in the body 110 of the smokeless cigarette 100 completely blocks the openings of the body 110 Thereby completely preventing the fragrance of the raw material medium 102 provided inside the body 110 from deviating to the outside.

As shown in FIG. 6, in the cigarette case 10, the smokeless cigarette 100 is disposed at one side edge of the cigarette case 10, and the common cigarette 100a can be disposed at the remaining portion. The first identifier # 1 is displayed on two cigarettes 100a closest to the smokeless cigarette 100 for the sensory evaluation of the common cigarette 100a in contact with the smokeless cigarette 100, And the second identifier # 2 may be displayed on the farthest cigarette 100a.

The following table shows the result of sensory evaluation of the inhalation device.

As shown in the above table, it is confirmed that the p value is not more than 0.05 in all of the five items (odor of outergocidal odor, extrinsic strength, pre-smoking odor, smoking hobbies, taste and aroma harmony) The smokeless cigarette 100 and the common cigarette 100a are formed together by applying the shutoff cap 150 to the body 110 of the smokeless cigarette 100 to produce the smokeless cigarette 100 Can not be transferred to the general cigarette 100a.

Hereinafter, how the air flow (air flow) is formed according to various forms of the mouthpiece portion will be described with reference to the drawings.

FIGS. 7A to 7C are views showing various forms of the body part of the smokeless cigarette, FIGS. 8A to 8C are views showing the airflow distribution according to the shape of the body part shown in FIGS. 7A to 7C, 7B and 7C show the airflow distribution when the smokeless cigarettes are at the same pressure.

7A has a shape in which a paper filter 140a is spaced from the mouthpiece portion 111a by a predetermined space of 5 mm and the body portion 110b shown in FIG. The structure 113b is provided at the portion 111b of the mouthpiece portion 111b (the interval from the end portion of the mouthpiece portion 111b to the structure portion 113b is 10 mm) and instantaneous airflow expansion is made through the structure 113b. The body part 110c shown in Fig. 7c is a structure in which the structure 113c is provided at the mouthpiece part 111c (the distance from the end of the mouthpiece part 111b to the structure 113b is 3.5 mm) 113b of the mouth piece portion 111c and has a structure in which an instantaneous airflow expansion is made through the structure 113c.

As a result of CFD (Computational Fluid Dynamics) simulation, in the case of a smokeless cigarette having the configuration shown in Fig. 7A, as shown in Fig. 8A, the airflow has a maximum velocity at the time of discharge of about 4.2 m / s, In the case of the unleaded cigarette, as shown in FIG. 8B, the flow rate increases to 19.1 m / s as the airflow passes through the structure 113b, but after that, the entire flow is uniformly spread and the maximum flow velocity is reduced to 1.6 m / As shown in Fig. 8C, in the case of the smokeless cigarette having the configuration shown in Fig. 7C, the flow rate increases to 18.2 m / s and the maximum flow rate to 14 m / s .

7c, the mouth piece portion 111c is formed so that the airflow instantaneously expands and the maximum flow velocity can be increased when the air flow is formed in the structure 113c region in the mouthpiece portion 111c, It is preferable that the interval from the end (opening) to the structure 113c is 0 to 6.4 mm.

In the case of the smokeless cigarette shown in Figs. 7B and 7C, as shown in Figs. 8A and 8B, since the discharge lengths of the airflow passing through the structures 113b and 113c are relatively different, In the case of cigarettes, the recirculation zone may be relatively large.

In this way, the instantaneous airflow can be expanded through the structures 113b and 113c, and the maximum flow rate can be increased to improve the user's mouth feel.

As described above, according to the embodiment of the present invention, the flavor ingredient can be smoothly transferred by the inhalation of the non-combustion or non-heating type, so that the user's satisfaction of smoking can be improved, and the overall appearance of the smokeless cigarette It is similar to the shape of general cigarette, so it has the advantage of keeping the user 's feeling of smoking similar to the existing one.

In addition, the smokeless cigarette 100 and the common cigarette 100a are combined to manufacture the suction device 1. At this time, the smokeless cigarette 100 has a structure for preventing the incense transfer, so that the smell of the smokeless cigarette 100 The cigarette of the present invention can be prevented from being transferred to other common cigarettes, so that it is possible to maintain the satisfaction of smoking of the general cigarette.
