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 individually installing a smoke inhaling passage 2 and a smoke exhaling passage 3 in a pipe 7, providing the interior on the tip side of the smoke inhaling passage 2 with a tobacco inserting part 4, filling a filter 5 in the interior of the smoke exhaling passage 3, respectively providing the smoke inhaling passage 2 and the smoke exhaling passage 3 with partition walls 15 and 15' in base ends for communicating through connecting holes 14 and 14' with a ventilating hole 13 and an inhaling and vent hole 12, arranging a check valve 16 for opening the connecting hole 14 at the time of inhaling the smoke and closing the connecting hole 14 at the time of exhaling the smoke on the side of the inhaling and vent port 12 in the smoke inhaling passage 2, arranging a check valve 16' for closing the connecting hole 14' thereof at the time of inhaling the smoke and opening the connecting hole 14' at the time of exhaling the smoke on the side opposite the inhaling and vent port 12 in the smoke exhaling passage 3, attaching a flexible tube 6 to the tip of the smoke exhaling passage 3 and providing the tip side of the flexible tube 6 with a check valve 11 for opening a connecting hole 10 when drawing the flexible tube 6 to this side and closing the connecting hole 10 when pushing back the flexible tube 6 on the tip side of the flexible tube 6.

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]

According to the present invention, in order to achieve the above object, a smoking pipe is provided in each of a smoke intake passage and a smoke exhaust passage, and a cigarette insertion portion and a check valve are provided at both ends of the smoke intake passage. On the other hand, the flue gas passage is filled with a filter, and a flexible tube and a check valve are provided at both ends, and a check valve is provided at the tip of the flexible tube. The rear end of the smoke intake passage and the smoke exhaust passage is a smoking pipe characterized by having a ventilation hole and a suction / exhaust port shared by the smoke intake passage and the smoke exhaust passage.

[0005]

1 to 3 show an example of an embodiment of the present invention.

FIGS. 1 to 3 show an embodiment of the present invention, and FIG. 3 is a sectional view taken along line AA of FIG. The pipe 7 is provided with a smoke intake passage 2 for a smoke passage at the time of smoke absorption and a smoke exhaust passage 3 for a smoke passage at the time of smoke exhaustion. The smoke intake passage 2 has a tobacco insertion portion 4 and a stopper 8 for stopping the insertion of the tobacco subsequent to the tobacco insertion portion. The smoke exhaust passage 3 is filled with a filter 5 therein, and the smoke intake passage 2 and the smoke exhaust passage 3 are each connected with a connection hole 1.
Partition walls 15 and 15 'are provided at the base end communicating with the ventilation holes 13 and the air intake / exhaust ports 12 via the air holes 4 and 14'. The check valve 16 is connected to the intake and exhaust ports 12
On the side. In the flue duct 3. A check valve 16 ′ is provided on the side opposite to the intake / exhaust port 11, which closes the connection hole 14 ′ at the time of smoke intake and opens at the opposite side of the intake / exhaust port 12 at the time of smoke exhaust and communicates with the smoke path. A flexible tube 6 is attached to the end of the flue gas passage 3, a partition wall 9 having a connection hole 10 is provided inside the end of the flexible tube 6, and when the flexible tube 6 is pulled toward the user, the flexible tube 6 opens toward the end. A check valve 11 that opens the connection hole 10, communicates the smoke path, and pushes out the front end of the flexible tube 6 to close the connection hole 10 is provided on the front end side of the flexible tube 6. 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. While smoking, a tobacco is inserted into the tobacco insertion portion 4 of the smoke intake passage 2 and ignited in the same manner as a conventional smoking pipe.
It is possible to remove the harmful substance of the smoke in the mouth with the filter 5 and easily exhaust the gas.

[0008]

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 was difficult with ventilation equipment such as air purifiers. Can be prevented. A flexible tube is provided in the flue duct, so the act of pulling out the flexible tubing in the flue duct and pushing it out several times is repeated several times to facilitate the exhaust of smoke in the mouth. 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.
