DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. The first chamber (11) of the pipe body (A) has a semi-circular shape in the upper part, but has a rectangular shape in the lower part, as shown in FIG. The second chamber 12 has a rectangular shape as shown in FIG. The pipe body (A) is made of a heat-resistant and rust-resistant material, for example, an aluminum alloy die-cast product.

The breathable tobacco holding pipe (10) housed in the first chamber (11) is made by fixing a glass fiber braided tube to a plastic tube section (D) shorter than the filter section of the cigarette. The outside diameter of the cylinder is appropriately smaller than the inside diameter of the first chamber, so outside air is sucked from the peripheral wall of the pipe (10), and smoke is transmitted when not sucked. Make up.

In this example, four smoke-absorbing filters (f) are provided on the upper surface of the first chamber (11). This filter smokes out when it is not sucked out and discharges outside air when sucked. Is filtered and supplied into the first chamber (11). This smoke-absorbing filter (f) is a sheet-shaped body in which a nonwoven fabric and a urethane foam containing activated carbon are laminated.

The internal structure of the cartridge type smoke exhaust filter (13) housed in the second chamber (12) which is separated from the first chamber (11) by the airtight partition wall (s) is , In this example,
A sheet-shaped body in which a non-woven fabric is sandwiched between two front and back sheets of paper and urethane foam containing activated carbon are alternately arranged in the length direction of the filter. In addition, the sheet-like body is a corrugated corrugated corrugation, and two pieces of the corrugated corrugated having the opposite directions are interposed between the disc-shaped urethane foam at the center and the disc-shaped urethane foam at both ends. I am allowed to do it. The outer peripheral surface of the smoke exhaust filter (13) should be in close contact with the inner peripheral surface of the second chamber (12) without any gap.

Inside the mouthpiece (B) which is airtightly and easily fitted (i) to the pipe body (A), the third chamber (23) is on the same axis as the first chamber (11). However, the fourth chamber (24) is formed adjacent to each other on the same axis as the second chamber (12). The third chamber (23) of the mouthpiece (B) has a smoke suction hole (16) surrounded by a stopper (15) with a protrusion (14) for supporting the base of the tobacco holding pipe (10). On the other hand, the fourth chamber (24) has a smoke exhaust hole (18) surrounded by a stopper (17) which is in contact with the base of the smoke exhaust filter (13).

In the smoke suction hole of the third chamber (23) of the suction port (B),
When a smoker inhales it opens towards the tip opening (t),
A smoke suction valve (19) is provided as a check valve that closes in the opposite direction, that is, when smoke is blown out from the smoker's mouth. On the other hand,
Communication hole (20) formed in the partition wall between the third chamber and the fourth chamber (24)
A smoke exhaust valve (21) as a check valve whose operating direction is opposite to that of the smoke intake valve (19) is provided in the. The lower part of the outer shell that extends cylindrically toward the tip opening (t) to form the third chamber (23)
(y) bends in an inverted L shape to reach the lower part of the main body (A), and forms the fourth chamber therein. In other words, this reverse L
The letter-shaped shell not only forms the required chambers, but also makes it easier for smokers to hold in their mouths.

The pipe lid (C) is also hermetically fitted (i) to the pipe body (A) in an airtight and easily removable manner.
Air supply hole (3) facing the tip side of the tobacco holding pipe (10) in (A)

(33) and a switch (34) to be pushed for ignition are attached. In consideration of convenience of battery replacement, the battery (33) is structured such that the adapter (a) having a removable structure is fitted (i) to the tip of the lid (C). The symbols (p), (n), (h) in the figure
Symbols (N) and (N) indicate a (+) side terminal, a (−) side terminal, a wiring and a nichrome wire, respectively. The number (32a) is the heater socket, and the number (32b) is the heater guard.

In using the smoking pipe as described above, first, as shown in FIG. 3, the mouthpiece (B) is connected to the pipe body (A).
Away from the cigarette holder pipe (10) having the plastic tube portion (D) fitted and supported in the mouthpiece and protruding (14).
Pull out from. Then, the residual ash inside is shaken off, a new cigarette (T) is attached, and the mouthpiece (B) is fitted again to the main body (A). After that, the switch (34) of the lid (C) is pushed while sucking from the mouthpiece (B) to confirm that the tip of the cigarette (T) is ignited, and then the switch is turned off. After smoking, remove the mouthpiece (B) and take out the cigarette, extinguish the fire and throw it away,
Even if the cigarette being smoked is left to be stored inside, the smoke absorbing filter (f) and the tobacco holding pipe
Since the oxygen supply from (10) is limited, it extinguishes naturally,
In addition, since it is covered with the heat-resistant body (A) during that time, there are few safety problems.

The cartridge type smoke exhaust filter (13) which may be clogged relatively early can be easily replaced with a new one by separating the suction port (B) from the main body (A) as shown in FIG. You can Note that the smoke suction valve in the suction port (B)
There is a risk that tar will accumulate at the locations of (19) and the smoke exhaust valve (21), but this can also be easily cleaned by removing the suction port. The replacement of the battery is also shown in FIG. 3 and its details are as described above.

Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments, and has the above-mentioned constitutional requirements referred to in the present invention, and The present invention can be carried out by appropriately modifying it within a range that achieves the object of the present invention and has the following effects. For example, by arranging the ignition battery (33) and / or the heating element (32) on the side of the main body (A), the length from the mouthpiece (B) to the tip can be further shortened, which is given to the user. There is an advantage that resistance can be reduced. Suction part (B) and lid
A small hinge (hinge) and a click-fitting method are used together as a means for connecting (C) to the pipe body (A), and further, smoke exhaust to reduce the smoke exhaust filtration resistance received from the filter at the time of blowing out. Of course, it is also possible to appropriately change the length or the internal structure of the filter.

[0019]

Since the smoking pipe of the present invention is constructed as described above and the smoke exhaust of the cigarette is purified, the smoke exhaust does not directly inconvenience a smoker in the vicinity and can smoke with confidence. .. Moreover, since an ashtray is not required during smoking and the risk of a fire due to leaving an ignited cigarette can be eliminated, it is possible that smoking will be permitted in the future even in places where smoking is currently prohibited. Russ.

Furthermore, since a battery-type heater is used for igniting a cigarette regardless of a flame such as a lighter or a match currently used, a burn or fire accident can be greatly suppressed. Further, the smoking pipe of the present invention does not require much cumbersome method of smoking and maintenance of smoking equipment, and can be used for a long period of time by renewing or cleaning each part, like a conventional kisel. For that purpose, the outer surface of the main body (A) or the like can be mainly provided with an arbitrary and appropriate decoration.
