Description

[Detailed description of the invention] This invention relates to a smoking pipe in which the amount of air sucked can be adjusted as desired.

An air hole is opened at the tip of the pipe body with a mouthpiece integrally formed at the rear end, and this air hole can be arbitrarily adjusted using a rotating means to adjust the amount of air sucked in during smoking, and to adjust the combustion temperature of the cigarette. Smoking pipes designed to reduce the amount of smoke smoked are already known.

The problem with this type of smoking pipe is that the structure of the tip of the main body is different from that of a normal smoking pipe because an air hole or a member that adjusts the opening of the air passage connected to the air hole is attached to the tip of the pipe body. This is complicated, leading to an increase in cost, and the airtightness between the adjustment member and the adjustment member is poor, making it impossible to effectively control the intake air amount due to air entering from locations other than the air holes.

This idea simplifies the tip structure of the pipe body, and also improves airtightness even more than the conventional structure.
This makes it possible to ensure the adjustment of the amount of intake air and further enhance the effect of removing harmful components produced during smoking.

This invention for the above purpose includes a pipe body with a mouthpiece that can contain an adsorbent together with a container, and a pipe that is attached to the tip of the pipe body to fix the adsorbent container, and a cigarette receiver to be used as a smoker. It consists of a support tube that is rotatably held around the cigarette end, and an adjustable air passage is provided between the support tube and the cigarette insertion tube.

This invention will be explained in detail below using illustrated examples.

In the figure, reference numeral 1 denotes a pipe body, which has a suction port 2 integrally formed at its rear end, and whose tip is opened by threading around the periphery.

A cylindrical container 4 filled with an adsorbent 3 such as silica gel is inserted into the interior of the pipe body 1, with a through hole provided at the center of both ends and a portion thereof protruding outward from the opening.

Reference numeral 5 denotes a support tube at the tip of the pipe body, which is a short cylindrical body, and is attached by screwing its threaded open end to the open end of the pipe body 1, and the container 4 is supported by a stepped portion 6 provided inside the main body. It is firmly fixed between the inside edge.

A partition plate 8 with a flue 7 protruding from the center is integrally formed at the other end of the support tube 5, and a required number of air (L9, 9 is perforated.

Reference numeral 10 denotes a cigarette receiving tube formed with a short tube, and is divided into a cigarette insertion opening 10a and a rear end fitting portion 10b by an inner wall 11 integrally formed inside the rear part.

Further, the open end of the rear end fitting portion 10b is formed to airtightly fit into the step portion 5a provided on the outer periphery of the end portion of the support tube 5.
The inner wall 10C between the fitting end and the inner wall 11 has a second
As shown in the figure, the thickness is gradually increased so that the distal end 10d collides with a protrusion 7b provided at the proximal end of the flue wall 7a.

And an air hole 12 is provided in the vicinity of the distal end 10d.
is perforated.

The cigarette receiver 10 formed as described above is connected to the support tube 5 by rotatably fitting the inner wall 11 into the flue wall 7a, and the O-ring 13 and washer 14 are inserted into the insertion port 10a. After fitting around the flue wall 7a, the hollow screw 15 inserted through the insertion port is screwed into the flue wall and firmly fastened to the support tube 5.

The cigarette receiver 10 attached as described above can be rotated around the flue 7.

Furthermore, by attaching the cigarette receiver 10, an air passage 16 is formed between the partition plate 8 and the inner wall 11, which communicates the inner and outer air holes 9, 12, and the air passage 16 is gradually made thicker. Since the space is formed narrowly by the inner wall 10C, the amount of air sucked in is adjusted as the cigarette receiver 10 rotates.

Furthermore, when smoking, cigarette smoke and air flow into the container 4 according to the suction force, and tar and nicotine in the smoke are absorbed by the adsorbent and removed.

As mentioned above, this invention includes a smoking pipe with a pipe body 1,
The support tube 5 at the tip and the cigarette receiver 1 at the tip
The inner wall 11 of the cigarette receiver 10
is fitted around the flue 7 protruding from the partition plate 8 of the support tube 5 and screwed so as to be rotatable, and the internal and external air holes 9 and 12 are communicated between the partition plate 8 and the inner wall 11. , and has an air passage 16 that allows adjustment of the suction amount.
The structure is extremely simple and easy to assemble, and adjustments can be made reliably.

Furthermore, since the cigarette receiver 10 is fastened using the O-ring 13, the area around the flue is sealed airtight, and air will not flow in from the gap beyond the adjusted amount.

However, since the cigarette receiver is given the elasticity of the O-ring, a moderate amount of rotational resistance is generated there, and it is possible to rotate the cigarette receiver to any position and place it in place without using a stopper. It has features such as being able to
