Description

[Detailed Description of the Invention] The present invention relates to a mini-pipe for cigarettes, and particularly to a mini-pipe that has a simple structure and is highly effective in removing harmful components such as tar from cigarette smoke.

Conventionally, various proposals have been made regarding minipipes for cigarettes.

For example, in order to remove harmful components from cigarette smoke, there were pipes that contained water-containing materials or special adsorbent materials, but these all had the disadvantage of complex structures and high costs. .

Furthermore, a simple mini-pipe that does not contain these materials has the problem of being insufficiently effective in removing harmful components.

The present invention has been made in view of the above facts, and its purpose is to provide a mini-pipe that is simple in structure, inexpensive to manufacture, and highly effective in removing harmful components of cigarette smoke.

The present invention consists of a substantially cylindrical mini-pipe made of plastic, consisting of three parts, the first part of which is a cigarette support member with a cigarette insertion opening at one end, and the end face of the other end is closed in a blind shape. A plurality of smoke exhaust ports are provided on the inner side of the pipe wall surface at this end surface.

The second part is an intermediate member, one end of which fits into the cigarette support member of the first part, and the other end of which is closed in a blind manner, and the central part of this end face is fitted with the cigarette support member of the first part. A cylindrical protrusion protrudes in the direction,
The protrusion is positioned such that cigarette smoke discharged from the smoke outlet provided in the cigarette support member collides with the end face of the protrusion.

Further, on the end face of the intermediate member, one or more smoke exhaust ports are provided between the protrusion and the inner side of the pipe wall surface.

The third part is a suction member, one end of which fits into the intermediate member of the second part, and the other end of which is provided with a suction port.

A collision surface is provided near the end on the mating side at a position where cigarette smoke discharged from the smoke exhaust port provided in the intermediate member collides with each other, and a partition wall is provided between this collision surface and the intake port. is provided.

The mini-pipe of the present invention is constructed as described above, and each of the three members can be easily manufactured by plastic injection molding, and assembly is only by fitting each member, so an extremely inexpensive mini-pipe can be provided. can.

Moreover, harmful components in cigarette smoke can be effectively removed because the smoke collides with the collision surface twice.

An embodiment of the mini pipe according to the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view showing an embodiment of the present invention, and FIG. 2 is a partially sectional exploded perspective view thereof.

In the figure, A is the cigarette support member, B is the intermediate member, and C is the cigarette support member.
are mouthpiece members, each of which is approximately cylindrical in shape and made of plastic acid.

A cigarette insertion opening 1 is provided at one end of the cigarette support member A, and a stepped portion 2 on which a cigarette comes into contact is formed at the middle portion of the inner peripheral surface.

A blind end surface 3 is provided on the end surface of the stepped portion 2 on the opposite side of the cigarette insertion opening 1.
A plurality of smoke exhaust ports 4 are formed through the central portion of the pipe.

A circumferential gap 6 is provided between the stepped portion 2 and the pipe wall surface 5.
is formed and serves as a means for fitting with the intermediate member B.

A notch 7 that fits into the gap 6 is formed at one end of the intermediate member B facing the cigarette support member A;
A blind end surface 8 is integrally formed at the other end.

A cylindrical protrusion 9 that protrudes toward the cigarette support member A is integrally formed in the center of the end face 8, and in this embodiment, the interior of the protrusion 9 is hollow.

One or more elongated smoke exhaust ports 11 are formed between the protrusion 9 on the end surface 8 and the inner peripheral surface of the pipe wall surface 10.

A notched cylindrical sleeve 12 is integrally formed at the lower part of the end face 8, and serves as a means for fitting with the mouthpiece member C.

A fitting part 1 having an inner periphery 13 that fits with the outer periphery of the sleeve 12 is provided at one end of the mouthpiece member C facing the intermediate member B.
4 is formed, and inside it there are two parallel partition walls 1
5 are integrally formed.

A suction port 16 is integrally formed at one end of the suction port member C facing the intermediate member B and one end on the opposite side, and the inner wall surface of the suction port 16 is parallel to the inner extension of the partition wall 15. It is provided.

These cigarette support member A1, intermediate member B, and mouthpiece member C are each integrally injection molded from plastic.

After the three members of the mini pipe according to the embodiment of the present invention configured as described above are integrated by fitting each other, a cigarette is inserted into the cigarette insertion port 1 of the cigarette support member A, and the mouthpiece member When you inhale the smoke from the cigarette while holding C in your mouth, the cigarette smoke passes through the smoke outlet 4 and collides with the collision surface, which is the end surface 9a of the protrusion 9 provided on the intermediate member B. It collides with the collision surface 17 located at the bottom between the outside of the partition wall 15 and the inside of the inner periphery 13 of the suction member C, rises again along the partition wall 15, and is sucked in through the suction port 16.

During this time, the cigarette smoke collides twice with the collision surfaces 9a and 17, so that harmful components in the cigarette smoke can be effectively removed.

Furthermore, the three members constituting the mini-pipe of the present invention can be easily manufactured by plastic injection molding, and assembly is only by fitting, which has the advantage of extremely low costs.

As detailed above, the mini-pipe of the present invention is assembled by fitting three members whose bottoms are integrally formed by injection molding of plastic, and moreover, the mini-pipe of the present invention is assembled by fitting together three members whose bottoms are integrally formed by injection molding of plastic, and what is more, the mini-pipe is assembled by fitting together three members whose bottoms are molded into one body by plastic injection molding. Since it is made to collide, the dog has the advantage of being able to provide a mini-pipe that is extremely low in manufacturing cost and can reliably remove harmful components from cigarette smoke.
