Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette deodorizer for removing the odor of tobacco. The cigarette deodorizer of the present invention is used, for example, by placing it on a smoking place in a restaurant, office or home. Suitable to do.

[0002]

2. Description of the Related Art As a method for treating the odor of combustion exhaust gas from cigarettes filled in a specific space, such as a room, an adsorption method using activated carbon, a masking method using other fragrance, or a chemical reaction of odorous substances Then, the odorous substances are removed by a chemical method, or the discomfort is reduced.

As the adsorption method using the above-mentioned activated carbon,
For example, stationary or portable fan suction deodorizers are known, but the deodorizing performance of activated carbon deteriorates in a short period of time because the odor of tobacco contains fine particles called aerosol mainly containing tar. Therefore, a filter for sucking the aerosol is required. Moreover, even if such a filter is used in combination, there is a fundamental drawback that the adsorbing capacity of acetaldehyde (CH ₃ CHO) contained in the combustion exhaust gas is small, and as a result, the fan suction type deodorizer does not It is not preferable because it is diffused in the room.

In the masking method using other fragrances, the fragrance used may give a new discomfort.
An aerosol mainly composed of tar adhering to the surface of a room wall or equipment is not a fundamental solution because there is a problem that even if it can be masked, it will discolor and spoil the appearance. Further, as a chemical method for removing a malodorous substance by a chemical reaction, for example, a method of oxidizing and decomposing a malodorous gas with ozone can be considered, but this causes new harm because excessive ozone is harmful to the human body. There is a risk. That is, since it is difficult to control the amount of the chemical substance that reacts stoichiometrically with the foul-smelling gas substance, unnecessary chemical substances will remain, and it is difficult to make a fundamental solution.

[0005]

As described above, it is extremely difficult to collect the odor once diffused in a specific space, such as a room, in the main body of the deodorizer, which is a very inefficient deodorizing method. For example, if the combustion exhaust gas of cigarettes is generated at a position approximately 1 m apart at the same level as the fan suction type deodorizer, most of the combustion exhaust gas of the cigarette will reach the deodorizer within 1 minute from the source. It was confirmed that there was nothing, and most of them were diffused in the room, which made it impossible to measure the amount and time of reaching the deodorizer. That is, fine particles such as tar in the combustion exhaust gas of cigarettes are easily attached to the surface of a room wall or equipment, for example, while diffusing into the room, and the ratio of being sucked into the deodorizer is extremely low. Met.

[0006] According to the published survey data, it is said that the actual time taken for a person to smoke is about one minute within the seven minutes which is the average time required from lighting a cigarette to extinguishing it. , The discharge time of sidestream smoke emitted directly from cigarettes into the atmosphere is longer than the discharge time of mainstream smoke emitted through the human body. In addition, the mainstream smoke that a person inhales and then exhales is because the filter provided at the mouth of the cigarette and the lungs of the person function as a filter and adsorbent, so that the majority of the combustion exhaust gas comes directly from the cigarette into the air. It is desired to suck and deodorize sidestream smoke emitted to the air before it is diffused into the air.

There are many kinds of tobacco odor components, and there are two kinds of tobacco odors, those contained in fine particles called aerosol mainly composed of tar and those completely gasified. However, just removing acetaldehyde and ammonia, which account for the majority of gas components, does not completely eliminate the odor that people feel. That is,
In the deodorization technology that removes the odor of tobacco, first, the aerosol components such as tar that adhere to the surface of the deodorant and inhibit the deodorizing effect are removed first, and then the acetaldehyde and ammonia, which account for the majority of the gas components, are removed. However, conventional activated carbon is not suitable for it, and it has been desired to develop an economical deodorizing material having a large adsorption capacity for both of them.

Therefore, the present invention eliminates the above-mentioned problems of the conventional cigarette deodorizing technology, removes aerosol components such as tar, and removes gaseous odor substances such as acetaldehyde and ammonia. To provide.

According to still another preferred aspect of the present invention, there is provided a cigarette deodorizer in which the cylindrical body of the dust collecting filter storage portion is vertically divided into two parts.

[0014]

The cigarette deodorizer according to the present invention, by placing the cigarette in the middle of smoking on the ashtray arranged at the lower end of the deodorizer,
Since the combustion exhaust gas generated from cigarettes is sucked directly above it, the combustion exhaust gas can be sucked in without diffusing it, and the aerosols such as tar in the sucked combustion exhaust gas can be adsorbed and removed by the dust collection filter, and then the composite gas above Since the deodorant layer deodorizes the gaseous malodorous source, the deodorizing performance is stable for a long period of time, and the sidestream smoke can be treated before being diffused.

Further, since the cigarette deodorizer according to the present invention deodorizes the gaseous malodorous source by the deodorant layer supporting the metal salt hydrazine double salt and the activated carbon layer, acetaldehyde and ammonia, which make up most of the gas components, are metallic. The salt-hydrazine double salt effectively deodorizes, and nicotine and other gaseous malodors can be effectively deodorized by the activated carbon layer.

Further, since the cigarette deodorizer according to the present invention is provided with the suction fan on the detachable lid member, the deodorant layer and the dust collecting filter can be replaced by removing the lid member from the cylindrical body, and the periodical operation is possible. There is an advantage that general maintenance becomes easy.

Further, the cigarette deodorizer according to the present invention has a configuration in which the opening / closing lid is provided on the tubular body of the dust-collecting filter storage portion or the tubular body is vertically separable into two parts, thereby collecting dust with heavy dirt. The filter can be replaced independently of the deodorant layer, making periodic maintenance easy.

Hereinafter, the present invention will be specifically described based on the embodiment shown in FIG. 1 attached, but it goes without saying that the scope of the present invention is not limited to this embodiment. FIG. 1 is a sectional view showing the outline of the configuration of the device of the present invention. The main body of the device of the present invention is composed of a tubular body 1. The cylindrical body 1 has a circular horizontal cross section, so that the processing efficiency of the combustion exhaust gas of cigarettes described later becomes good. The horizontal cross section of the tubular body 1 is not limited to a circular shape, and may have any shape from the viewpoint of design, such as an elliptical shape, a polygonal shape, or a quadrangular shape.

According to the present invention, the fan 2 is provided above the tubular body 1.

If the plate member 6 is fixed to the lower end of the column 3, the ashtray 5 can be placed on the plate member 6, and when the present apparatus is moved, the ashtray 5 can be moved together. Inside the tubular body 1, a dust collecting filter 7 and a composite deodorant layer 8 are provided from the lower layer.

In the cigarette deodorizer configured as described above, when the fan 2 is driven during smoking, air is sucked into the tubular body 1 to form an upward flow. When the cigarette 9 in the middle of smoking is placed on the ashtray in this state, the combustion exhaust gas is accompanied by the upward flow of air, and first, the aerosol such as tar is adsorbed and removed in the process of passing through the dust collecting filter 7. Then
The combustion exhaust gas that further rises is the composite deodorant layer 8 (8-1:
Deodorant layer consisting of metal salt hydrazine double salt, 8-2: Activated carbon deodorant layer), a gaseous malodorous source is adsorbed in the process of passing through.
The air that has been decomposed and removed and is purified is discharged from the upper end of the tubular body 1.

In order to efficiently deodorize various gaseous malodorous sources in the above combustion exhaust gas of cigarettes, it is necessary to select a deodorant suitable for each kind of malodorous source and use it as a composite deodorant. . The present invention is a double salt produced by adding hydrazine to an aqueous solution of a metal salt as a deodorant having a high deodorizing performance with respect to acetaldehyde, ammonia, etc. which are contained in a large amount in the combustion exhaust gas of cigarettes and are hardly adsorbed by activated carbon. The deodorizing agent 8-1 carried on the substance and the activated carbon layer 8-2 for deodorizing nicotine and other malodorous sources are used together.

The deodorant 8-1 in which the above metal salt hydrazine double salt is supported on a porous material is, for example, a sulfate or hydrochloride of aluminum, titanium, nickel, cobalt, zinc or the like,
For example, a mixed aqueous solution of one or more metal salts of nitrate and hydrazine is 1: 0.5 to 0.5: 1 (molar ratio),
It is preferable to coat the porous material or soak it in the mixed aqueous solution, and then to dry it, preferably in an approximately equimolar ratio.
It is carried. As the above-mentioned porous substance, any known substance having fine irregularities or pores on its surface and structurally having a predetermined air permeability can be used, and honeycomb shape, plate shape, coil shape, string shape or particle shape can be used. Any of the deodorizing agents of can be used.

The activated carbon layer 8-2 is composed of activated carbon particles. Since the activated carbon particles are flammable and are used in the immediate vicinity of a burning cigarette, it is preferable to use the non-combustible activated carbon particles in case of emergency.
Specifically, for example, it is preferable to use activated carbon particles coated with a non-combustible porous material such as sepiolite, or to store the activated carbon particles in a non-combustible and highly air-permeable box.

FIG. 2 shows a modified example of the present invention, in which a sirocco type fan 2 is provided on the lower surface side of a lid member 10 fitted on the upper part of the tubular body 1. The side surface and the lower surface of the fan 2 are covered with a breathable frame 11. The fan 2 is connected to a motor 12, which is supplied by an arbitrary power source, in this case a dry battery 13. 14 is a power switch.
The power source may be an AC power source. The breathable frame body 11 fixed to the lid member 10 is fitted on the upper end of the tubular body 1 and is detachably fixed. Provided on the inner surface of the cylindrical body 1 at a predetermined height position is a convex member 15 which detachably holds the dust collecting filter 7 and the composite deodorant layers 8-1 and 8-2. This convex member 15 is the tubular body 1.
It may be provided all around the inner surface of, or may be provided at predetermined intervals.

The deodorizer for cigarettes constructed as described above is used for a predetermined period of time and then deodorized by the deodorizing filter 7 and the deodorizing agent 8-1.
When replacing 8 and 8-2, the cylindrical member 1 to the lid member 10
By removing the deodorant, the activated carbon deodorant 8-1, the metal salt hydrazine double salt deodorant 8-2, and the dust collecting filter 7 can be taken out in this order, and can be easily replaced with a new one.

In the cigarette deodorizer constructed as described above, the surface pollution deterioration of the activated carbon deodorant 8-1 and the metal salt hydrazine double salt deodorant 8-2 is caused by the combustion exhaust gas treated by the deodorizing filter 7 to remove the aerosol. Since it passes through, the source of gaseous malodor such as acetaldehyde and ammonia is deodorized with the metal salt hydrazine double salt deodorant 8-2, and most of the other malodorous sources such as nicotine. Is deodorized with the activated carbon deodorizer 8-1, and the function is shared, so the load on the adsorption capacity is small. That is, since the lives of the activated carbon deodorant 8-1 and the metal salt hydrazine double salt deodorant 8-2 are longer than the life of the deodorizing filter 7, the deodorizing filter 7 needs to be replaced individually every predetermined period although it depends on the amount of smoking. is there.

In the case of simply exchanging the deodorizing filter 7 alone, for example, as shown in FIG. 3, an opening / closing lid 16 is provided in the accommodating portion of the dust collecting filter 7 of the cylindrical body 1,
The hinge 17 locks so that it can be opened and closed. It is preferable that the joint end portion of the opening / closing lid 16 and the tubular body 1 has an overlapping structure so as to obstruct gas flow. Then, the opening / closing lid 16 can be opened / closed and replaced with the prepared cassette type dust collecting filter 7.
The open / close lid 16 may be one-sided or two-sided.

Another mode in which the above-mentioned deodorizing filter 7 can be easily replaced independently is as shown in FIG.
The dust collecting filter 7 storage section is configured so that it can be vertically divided into two parts. The tubular bodies 1-1 and 1-2 are connected by the tubular body 1-1.
