Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pipe that mainly removes tar from smoke during smoking.

It is generally believed that the tar contained in cigarette smoke is harmful to the respiratory system when inhaled into the body.

To remove this tar, various types of pipes have been provided that allow it to be eluted into water, separated by jet action, or even removed using a filter. In either case, it is impossible to completely remove the tar, and if you try to increase the tar removal rate, a large suction force is required, and the removed tar accumulates in the pipe, so it is difficult to remove the tar at the beginning and after the suction. The taste changes over time, and the taste usually gets worse as tar accumulates.

In view of the above, the present invention aims to provide a pipe in which tar content is almost completely removed, the pipe itself has almost no suction resistance, and the taste does not change over time. The gist of this is that a heating chamber and a filter chamber are sequentially provided in the flue that communicates with the tobacco stuffing port and the suction port, a heating chamber such as a nichrome wire is provided in the heating chamber, and a filter is provided on the rear side of the heating chamber. The pipe is characterized by the fact that it is replaceably housed.

Next, embodiments of the present invention will be described with reference to the drawings.

In this pipe A, a first heat radiation tube 3, a heat-resistant material tube 4, and a second heat radiation tube 5 are connected in series between a tobacco filling port 1 and a suction port 2.

An exterior cylinder 6 is fitted concentrically to the outside of each of these cylinders with a space in between.

Both the first and second cylinders 3 and 5 are made of a metal material with high thermal conductivity such as aluminum, and the heating chamber cylinder part 4a is inserted into the center of the first cylinder 3 from the heat-resistant material cylinder 4. The interior is a heating chamber 7, and a heater 8 made of nichrome wire is accommodated within the heating chamber 7.

Both ends of the heater 80 are connected to the main body 4 of the heat-resistant material cylinder 4.
It is connected to power supply terminals 9, 9 which pass through the inside of b and protrude from the side thereof.

These terminals 9, 9 are implanted in the main body portion 4b of the heat-resistant material cylinder 4,
The tips thereof pass through the holes 10, 10 of the exterior cylinder 6 and protrude outward in a symmetrical arrangement with respect to each other.

On the other hand, the outside of the heating chamber cylindrical portion 4a is covered with an inner cylinder 11 having a cylindrical shape with a bottom.

This inner cylinder 11 is inserted in a concentric arrangement between the first cylinder 3 and the heating chamber cylinder part 4a with a space in between, and is fixed to the main body part 4b of the heat-resistant material cylinder 4 at its open end side.

A vent hole 11a is opened on the circumferential surface of the open end side, and smoke is passed through the vent hole 1a in the center of the filling port 1, the first cylinder 3, and the inner cylinder 1.
It passes in order between the ventilation hole 11a, the heating chamber cylinder part 4a, and the inner cylinder 11, and is introduced into the heating chamber 7.

Further, inside the second cylinder 5, a buffer plate 12 is fitted on the heat-resistant material cylinder 4 side, and a filter housing cylinder 13 is fitted on the suction port 2 side.
is embedded.

The buffer plate 12 is arranged at a distance from the ventilation hole of the heat-resistant material cylinder 4, and has ventilation holes 12a, 12a opened at its peripheral edge.The filter housing cylinder 13 is formed in a cylindrical shape with a bottom, and the bottom surface 13a of the buffer plate 12 is formed in the shape of a cylinder with a bottom. A ventilation hole 13b is opened in the center, and the second cylinder 5 is inserted from the suction port side end with the bottom surface 13a facing the buffer plate 12 side.

The filter 14 is inserted from the open end side of the filter housing cylinder 13.

In addition, as a power source for the heater 8, an AC-DC converter such as a calculator, a small radio, a small tape recorder, etc. is used, a car cigarette lighter socket is used, or a battery case containing many batteries is used. In this case, for example, as shown in FIG. 2, a clip-shaped power connector 15 is used, and contact terminals 16 are formed on both grip pieces 15a and 15b of the connector 15. By sandwiching and connecting this to the outside of the power supply terminals 9, 9, the heater 8 is energized.

In addition to the embodiments described above, the present invention may be implemented as shown in FIG. 22 are connected, a buffer plate 23 and a filter housing cylinder 24 are inserted into the other end side of the heat dissipation cylinder 22, a suction port 25 is fixed to the outside thereof, and an exterior cylinder 26 is attached, and the inside of the heat-resistant material cylinder 21 is A heater 28 made of nichrome wire is housed in a heating chamber 27 formed in a U-shape.

In a pipe constructed in this way, when the smoke from smoking enters the heating chamber, it comes into contact with the red-hot heater and the tar is burned, turning into ash, where most of the tar is removed.

This ash is then removed by a filter, and smoke containing almost no tar is drawn out into the inlet.

The pipe of the present invention is constructed as described above, and is equipped with a heating chamber in the flue and a red-hot heater inside the flue, so that the tar contained in the smoke comes into contact with this heater and is burned again and becomes ash. Since the smoke is removed by a filter, it is now possible to inhale smoke with almost no tar content, and unlike conventional methods, suction resistance does not increase due to tar removal, and there is no need for contact with the heater. Since it is instantly combusted and turned into ash, no tar remains in the pipe, and the taste does not deteriorate over time.

Furthermore, the contact time of the smoke with the heater differs depending on the inhalation speed, which results in different combustion conditions, allowing the user to enjoy different flavors of cigarettes depending on his/her preference.
