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 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 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 and providing the rear end of the smoke exhaling passage 3 with a vent hole 7.

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 flue gas channel was filled with a filter and the tip was equipped with a flexible tube. The above was provided with a suction port.
A smoking pipe is characterized in that a check valve is provided at the distal end of the flexible tube to facilitate exhaustion.

1 to 9 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 smoke exhaust passage 3 is filled with a filter 5 and a flexible tube 6 'is attached to the front end side, and communicates with an exhaust hole 7 on the rear end side.

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 pulling the flexible tube 6 'of the smoke exhaust passage 3 forward with the finger and holding it down with the finger so that the outside air does not enter, and then returning to the original position. .

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 8 is fixed to the tip 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.

FIGS. 7 to 9 show a third embodiment of the present invention. FIG. 9 is a sectional view taken along line AA of FIG. This is for facilitating the operation of the flexible tube 6 'of the flue gas passage 3. Flexible tube 6 '
A connection hole 10 is provided in the partition wall 9 at the tip of the partition wall 9. By pulling the tip of flexible tube 6 '
A check valve 11 that closes the connection hole 10 and opens the connection hole 10 when exhausting smoke is arranged. Therefore, when the flexible tube 6 'is pulled forward, the air in the flexible tube 6' is exhausted from the mouth at the tip. Conversely, when exhausting smoke, the exhaust gas that has passed through the exhaust gas passage 3 is opened by the check valve 11 to conduct through the connection hole 10 to facilitate the exhaust.

[0010]

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 path and a smoke exhaust path separately, and providing a smoke exhaust path filled with a filter, harmful tar content in cigarette smoke during exhalation of cigarette smoke inhaled in the mouth Substances can be removed accurately and efficiently, and the interior can be cleaned and released, effectively dispersing tobacco smoke into the interior, which is 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. The flexible tube in the flue gas passage reduced the air pressure in the flue gas passage and facilitated the exhaust of smoke in the mouth when exhausting. 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.
