Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improved cigarette smoking pipe, and its purpose is to eliminate nicotine, which is a harmful substance contained in cigarettes when smoking cigarettes.
The tar is thoroughly mixed with the air through the intake hole and the small holes in the insertion tube, etc., and is removed by an absorbent material, and this absorbent material can be replaced.Furthermore, the purpose is to adjust the intake air. By thoroughly mixing with air, nicotine, tar, etc. are removed, improving the taste of smoking, and the inside of the pipe can be cleaned easily.

A detailed explanation will be given below with reference to the drawings.
mainly consists of smoking pipes (hereinafter simply referred to as pipes).
One end is attached to the mouthpiece 1, and a tobacco insertion tube 2 is separately formed and attached to the opening at the other end, and an absorbent material B is inserted into the pipe so as to be replaced.

The main body of the pipe A is made of synthetic resin, and is molded with a mold from transparent synthetic resin or colored transparent synthetic resin, and the mouthpiece 1 is formed flat on both the front and back sides, and the mouthpiece end is slightly enlarged in width to form an enlarged part. 1a to make it difficult to get caught in the lips and fall off when bitten in the mouth. Therefore, there is no need to hold it in your hand, allowing you to use both hands. As shown in FIG. 2, the suction hole 1b is wide and horizontally elongated, and an upwardly facing step 3 is formed in the upper inner side thereof, with which the lower end of the absorbent material B engages. Further, a part of the periphery of the opening is cut out to form a notch a, and an intake hole 5 provided in the insertion tube 4, which will be described later, is positioned to adjust the amount of intake air.

Next, the insertion tube 2 is made of synthetic resin and has the same shape as the pipe main body A, but in a different color.The insertion opening end 2a into which cigarettes are inserted has a slightly rounded inner surface to make it easier to insert cigarettes into the inner surface. The pipe main body A side is formed into a small diameter cylindrical part 2b having a smaller diameter from approximately the middle of the circumferential surface so that even small diameter cigarettes can be inserted therein. Reference numeral 4 denotes a fitting tube portion to be inserted into the opening of the pipe main body A formed integrally below the insertion tube 2, and the outer circumferential surface has a small diameter and is formed into an inclined surface 4a with a smaller diameter toward the lower end so as to be closely spaced. Either by fitting or by providing an annular protrusion 4b and an annular groove on the outer periphery as shown by dotted lines to facilitate rotation,
It is formed so that it can be inserted closely into the opening of the pipe main body A, and furthermore, a small diameter cylinder 7 is formed in the center of the bottom surface so that the diameter becomes smaller as it goes downward.
The space between the small hole 8a and the inner circumferential surface of the small hole 8a is widened to allow sufficient mixing of the intake air from the small hole 8a and smoking.
In addition, by forming the fitting tube portion 4 to have a small diameter, two holes are placed at one point on the circumferential surface immediately below the step portion 2c with an interval as shown in FIGS. 1 and 3.
Two, three, etc. intake holes 5 are provided, and a stopper 6 is provided protrudingly. These are located and installed in the cutout window hole a of the pipe main body A, and the projection 6 of the insertion tube 2 is installed.
As shown in Fig. 3, if you turn the notch window hole a until it stops, both of the intake holes 5 will open, and if you turn it to the other side, the intake holes 5 will open one by one, and the pipe main body A will open.
FIG. 4 shows a state in which one of the intake holes 5 is closed and the other is open, thereby allowing the amount of intake air to be adjusted.

Next, the upper end of the small diameter cylinder 7 mentioned above, that is, the fitting cylinder part 4
A small hole 8a is formed in the bottom of the tube along the inner circumferential surface of the fitting tube part 4 at a symmetrical position with the small diameter tube 7 at the center so that outside air can be sucked in. Tar and nicotine during smoking can be removed by mixing the outside air sucked through the small hole 8a. In this space, smoking and outside air can stagnate and mix sufficiently with the outside air. As a result, nicotine, tar, and the like adhere to the outer circumferential surface of the small diameter tube 7 and further to the inner circumference of the insertion tube portion 4 on the upper surface of the small hole 8a, so that the tar and nicotine can be removed.

Next, absorbent material B is prepared by arranging a large number of synthetic fibers into a cylindrical shape and cutting them to the length to be inserted into the pipe main body A.The outer peripheral surface is solidified with a glue synthetic resin liquid so that the fibers can be replaced. It is formed so as not to be dispersed, and silica gel, herbal extract paste, herbal extract, paste drying preventive agent, fragrance, etc. are adsorbed between the fibers.

Since the present invention is constructed as described above, by rotating the insertion tube 2 and adjusting the two intake holes 5 of the intake hole 5, the amount of outside air sucked can be adjusted, and the amount of smoke can be reduced during smoking. Not only can you adjust the amount, you can remove nicotine, tar, etc., so you can enjoy smoking according to your preference, and it is also good for your health because it prevents a large amount of smoke from entering your mouth at once, which helps eliminate the scent in your mouth. Good results were obtained, and the adsorbent was equipped with the insertion tube 2 as described above.
Since nicotine, tar, etc. are adsorbed in advance in the outer circumferential space of the small diameter cylinder 7 and the small holes 8a, 7a, it is possible to reduce the adhesion of large amounts of nicotine, tar, etc. into the absorbent material B as in the conventional case, and it can be used for a long period of time. It can be used, and the effect can be further enhanced by replacing the absorbent material.
It shall have many advantages.
