Abstract

PROBLEM TO BE SOLVED: To obtain a smoking tool enabling the smoking of cigarette without emitting smoke from the tool. SOLUTION: A cigarette chamber 1 is separated from a filtration chamber 6 with a partition wall having a through hole 7. Another through hole 9 is opened on a partition wall between an air chamber 8 and the filtration chamber 6. The tool is provided with a forked pipe 18 having a leg branch connected to a puffing port 15 through a hose 17, one of the right and left branches connected to a cigarette holder 3 through a hose 20 and the other branch connected to a socket 11 through a hose 19. The smoke in the mouth is smoothly flowed by the expansion and contraction of the air chamber 8 and repeatedly refluxed to the cigarette chamber 1 under cleaning with activated carbon 14.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoking device designed so that smoke does not come out even if a user smokes a cigarette.

[0002]

2. Description of the Related Art There has been a smoke evacuator in which a fan is driven by a motor to discharge cigarette smoke.

[0003]

Cigarette smoke seems to be a problem both for smokers and non-smokers. The present invention was invented to solve these problems.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] A plug having a cigarette holder (3) with a suction check valve (4) is provided on the outlet side of a tachoco chamber (1). Provided on the inlet side of the filtration chamber (6) is a plug (10) having a socket (11) with a check valve (12) for blowing. The filtration chamber (6) and the air chamber (8) flow through the ventilation hole (9), and the filtration chamber (6) and the tobacco chamber (1) flow through the ventilation hole (7). The breathable cartridge (13) is filled with activated carbon (14) and inserted into the filtration chamber (6). The left and right mouths of the bifurcated tube (18) are respectively connected to the hose (19) and the hose (20), and one mouth is connected to the suction mouth (15) by the hose (17). A smoking article having the above structure.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When a lit cigarette (5) is inserted into a cigarette holder (3) and a mouthpiece (15) is sucked or blown, a suction check valve (4) and a blow check valve are shown. The tobacco chamber (12) and the air chamber (8) work automatically so that the smoke of the cigarette is purified while gently touching the surface of the activated carbon (14) having a very large surface area with a small volume while being purified. Inflow into 1). The air chamber (8) repeatedly contracts and expands in response to suction and blowing to circulate smoke smoothly.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. When the lit cigarette (5) is set in the cigarette holder (3) and the mouthpiece (15) is slowly sucked, the check valve for suction (4) opens, the check valve for blowing (12) is closed, and the smoke is not emitted. It comes into my mouth. If you smoke the cigarette and then blow it in gently, the smoke will become air (8).
If it is inflated and accumulated in it, it will be returned to the tobacco chamber (1) through the ventilation hole (7) and the smoke will be purified in the process. Because of the above-mentioned mechanism, if the sucking mouth (15) is not released from the mouth and is sucked gently, smoke does not go out.

[0007]

The present invention makes good use of the check valve which has a simple structure and operates properly, and the characteristics of activated carbon which exerts enormous cleaning power with a small amount. 1 good quality activated carbon
It has a surface area of 2500 m ^{2 /} g. That is, by using the smoking article of the present invention, a smoker can enjoy a delicious dose without bothering others and without hesitation.
