Abstract

PROBLEM TO BE SOLVED: To prevent unfavorable effects of the so-called passive smoking affecting persons other than a smoker due to hazardous substances contained in discharged smoke which is recently considered as a problem. SOLUTION: This smoking pipe 1 is obtained by installing a smoke inhaling passage 2 and a smoke exhaling passage 3 in the smoking pipe, filling a filter 5 in the interior of the smoke exhaling passage 3 and facilitating the smoke inhaling and exhaling. Furthermore, the smoking pipe 1 is prepared by individually installing the smoke inhaling passage 2 and the smoke exhaling passage 3, providing the interior on the tip side of the smoke inhaling passage 2 with a tobacco inserting part 4, attaching a flexible tube 6 to the side of the rear end, filling the filter 5 in the interior of the smoke exhaling passage 3, attaching a flexible tube 6' to the tip side thereof, providing the rear end of the smoke exhaling passage 3 with a vent hole 7, attaching a flexible tube 6' to the tip side and providing the side of the rear end of the flexible tube 6' with a check valve 10 and the tip side with a check valve 10'.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is suitable for efficiently removing carcinogenic substances such as tar components contained in discharged smoke, preventing the diffusion of tobacco smoke into the room, and preventing the adverse effects of passive smoking. It's about a smoking pipe.

[0002]

2. Description of the Related Art Conventionally, facilities for removing air pollutants such as cigarette smoke include air intake and exhaust fans and other ventilators, and desktop or wall-mounted air purifiers. However, since these facilities forcibly ventilate the air in the entire room, a large amount of power is required for driving the facilities, and the cost is high and the cost is high. And, the tobacco smoke is easily diffused throughout the room, and these facilities are ineffective in preventing the diffusion, and the efficiency of removing the tobacco smoke is not good. In recent years, the inconvenience of passive smoking, in which lung cancer is caused by indirect inhalation of cigarette smoke emitted by smokers by surrounding people, has become a problem. Measures are shouting strongly.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and requires an extremely simple structure and a low cost, so that it is easy to prevent tobacco smoke from diffusing into a room and to remove harmful substances. It is an object of the present invention to provide a smoking pipe which can be performed efficiently.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a smoke intake passage and a smoke exhaust passage separately, and includes a tobacco insertion section and a flexible tube at both ends of the smoke intake passage.
On the other hand, the smoke exhaust passage is filled with a filter inside, has an exhaust hole at the rear end, has a flexible tube at the tip, and has a check valve at the tip and the rear end of the flexible tube, respectively. It is a smoking pipe. Further, the smoking pipe is provided with a suction port.

1 to 6 show an example of an embodiment of the present invention.

FIGS. 1 to 3 show a first embodiment of the present invention, and FIG. 3 is a sectional view taken along line AA of FIG. The smoking pipe 1 is provided with a smoke intake passage 2 and a smoke exhaust passage 3 separately. The smoke intake passage 2 is provided with a tobacco insertion portion 4 inside the front end side, and a flexible tube 6 is attached and communicated with the rear end side. ing. The exhaust passage 3 is filled with a filter 5 and an exhaust hole 7 is provided at the rear end.
Attach the flexible tube 6 'to the tip,
Check valves 10 and 10 'are provided at the rear end and the front end of the flexible tube 6'. Check valve 10 has connection hole 9
The check valve 10 'is formed of a partition wall 8' having a connection hole 9 '. By pulling the distal end of the flexible tube 6 'forward, the check valve 10 closes the connection hole 9, and at the same time, the check valve 10'
Opens a connection hole 9 '. Therefore, the air in the flexible tube 6 'is exhausted from the mouth at the tip. Conversely, by pushing the tip of the flexible tube 6 ′ forward, the connection hole 9 opens in the check valve 10, and at the same time, the check valve 1
0 'closes the connection hole 9' and the exhaust gas that has passed through the smoke exhaust passage 3 is exhausted from the mouth at the tip. The smoke exhaust passage 3 and the flexible tube 6 'may be expanded from the smoke intake passage 2 in order to improve the exhaust effect.

A method of using the smoking pipe according to the above embodiment will be described. At the time of smoking, the tobacco is inserted into the tobacco insertion portion 4 of the smoke passage 2 and ignited in the same manner as the conventional smoking pipe, but in order to obtain an appropriate position interval between the flexible tube 6 and the exhaust hole 7, the flexible of the smoke passage 2 By bending the tube 6 or inserting a finger between the tube 6 and the smoke exhaust passage 3, the smoke can be easily absorbed and exhausted. At the time of smoke exhaustion, it is possible to easily exhaust the smoke in the mouth by repeating the act of pulling the flexible tube 6 ′ forward in addition to the smoke exhaust passage 3 and pushing it forward several times.

FIGS. 4 to 6 show a second embodiment of the present invention, and FIG. 6 is a sectional view taken along line AA of FIG. The use of the flexible tube 6 as the suction port is for responding to an aversive person, and the suction port 11 is fixed to the end of the flexible tube 6. This can also achieve the purpose by deforming the flexible tube 6. The method of use is as described above.

[0009]

Since the present invention has the above-described structure, it solves the above-mentioned drawbacks of the prior art and has the following unique effects. a. By forming a smoke intake passage and a smoke exhaust passage separately, and providing a smoke exhaust passage filled with a filter, the harmfulness of tar contained in cigarette smoke during exhalation of cigarette smoke sucked into the mouth is discharged. Substances can be removed accurately and efficiently, and the interior can be cleaned and released, effectively dispersing tobacco smoke into the interior, which was difficult with ventilation equipment such as air purifiers. Can be prevented. The provision of flexible tubes in the smoke intake and exhaust ducts has the following effects. 1. Smoke exhaustion in the mouth was facilitated by repeating the act of pulling out the flexible tube in the flue gas channel and then pushing it out several times. 2. The flexible tube in the smoke path facilitates the setting of an appropriate distance between the smoke path and the smoke path. b. Therefore, it is suitable for preventing the harmful effects of the passive smoking, in which the lung cancer occurs due to the indirect suction of the cigarette smoke exhaled by the smoker by the surrounding people. c. Unlike ventilation fans and air purifiers, the structure is extremely simple, and costs can be kept low.
