Description

[Detailed description of the invention] [Industrial application field] This invention relates to an ashtray used when smoking cigarettes.

[Conventional technology]

In recent years, awareness of the harmful effects of tobacco smoke has increased. The right to quit smoking is also becoming a civil right. In fact, measures have been taken to combat cigarette smoke, such as installing air purifiers indoors and providing non-smoking rooms in public facilities. Strategies cannot be implemented everywhere. It cannot be said that it is an effective measure as it is difficult to apply it in ordinary households. Therefore, there is a strong desire for a method that can easily and inexpensively eliminate the harmful effects of cigarette smoke.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a method that effectively prevents cigarette smoke damage and can be easily used in ordinary households.

[Means to solve the problem]

In order to solve the above problems, the ashtray according to the present invention includes:
A smoke purification filter section is provided above the ash receiving section.

The ash slag receiver is a part where ash and vibration absorbers (butts) accumulate, and for example, the receiver is dish-shaped and made of ceramic, metal, resin, or the like.

The smoke purification filter section is composed of, for example, a section for detoxifying harmful components and an adsorption section provided at the subsequent stage. moreover,
A heating mechanism may be added to the detoxification section to enhance the detoxification function. Further, a dust removal section may be provided before the detoxification section to prevent the smoke purification function from deteriorating.

The detoxification part has the function of decomposing harmful components and malodorous components in smoke to detoxify them. Inorganic porous materials such as those obtained by drying layered compounds (for example, clay-like substances) and those made of inorganic fibers are preferably used. These inorganic porous materials themselves have a certain degree of catalytic action, and can render harmful components harmless through heating reactions, etc., and can also be made to carry another catalyst to exert a stronger action. good. A catalyst may be inserted and supported between the eyebrows of the layered compound. In the case of supporting a catalyst, in addition to the above-mentioned supports, materials made of silicate compounds such as alumina, silica-alumina, etc. can also be used. Normally, the detoxifying part is often heated during use, but the temperature may reach about 300°C, so it is preferable that the carrier has high heat resistance.

Catalysts include platinum, ruthenium, palladium, manganese, nickel, cobalt, cerium, copper, chromium, silver,
At least one selected from metals such as molybdenum, tantalum, tin, titanium, iron, and zinc, or oxides of these metals is used.

In addition to the above, a substance having a strong catalytic action by itself, for example, an oxide catalyst such as a perovskite type catalyst, may be used as the detoxification part.

The adsorption section has a function of adsorbing and removing components sent from the detoxifying section, and for example, porous bodies such as activated carbon, molecular sieve, inorganic layered porous bodies, etc. are used.

Inorganic layered porous materials include, for example, inorganic materials (Si02, Ti1t, Alt, etc.) between the eyebrows of smectite minerals (montmorillonite, pennite, chlorite, beidellite, hectorite, synthetic mica, teniolite, etc.).
An aggregate of inorganic layered porous particles (intercalation compound) in which voids are maintained between the eyebrows by inserting carbon lumps, etc. An aggregate composed of porous particles and a binder material with good moldability such as diatomaceous earth or calcium silicate, or an aggregate in which the inorganic layered porous particles are supported on, for example, a glass cloth is used. .

In addition, as the adsorption part, a porous material is used in which the pore size distribution has peaks in both the micro size range of several tens to hundreds of micrometers and the small size range of several microliters to several hundred micrometers. It's okay. In this porous material, low-molecular components are adsorbed in the micro-sized pores, while high-molecular components and dust are adsorbed in the small-sized pores; This has the advantage that low-molecular components with weak adsorption properties can be effectively adsorbed. As such a porous body, for example, the above-mentioned smectite type mineral in a swollen state [if necessary, 5iOt, TiOz
, Act Ox , zro2 , Ge0z, Fetu
There is an inorganic porous body made of an aggregate obtained by drying in a supercritical state (inserted with an inorganic compound for inorganic pillars such as s) or an organic compound for organic pillars (for example, PVA, etc.).

Of course, the suction section is not limited to these. For example, materials made of alumina, zeolite, zirconium phosphate, layered compounds without pillars, etc. may be used.

As the dust removal part, nonwoven fabric, woven fabric, polyurethane foam, felt, glass fiber aggregate, paper, etc. are used alone or in combination. Of course, it is preferable that these materials have excellent air permeability.

As the heating mechanism, for example, an electric heater such as a ceramic heater or a ribbon heater is used.

It goes without saying that each part of the present invention may be constructed of other materials that perform the same functions as those exemplified above.

In addition, the ashtray of the present invention may have a structure in which one or more of the detoxification part, the suction part, the dust removal part, etc., can be replaced.If they are made replaceable, a cartridge system is preferable. The smoke purification filter section above the ash dregs receiver immediately purifies the highly harmful smoke (sidestream smoke) emitted from half-smoked cigarettes and butts placed in the ash dregs receiver before it spreads into the room.

Since it is shaped like an ashtray, it can be used easily anywhere. Moreover, the ashtray is an integral part of the act of smoking, and as long as the ashtray is left in place, the smoker will use the ashtray without consciously thinking about it, so the smoke purification function will surely work at the same time as smoking. It becomes like this.

The detoxification section performs a purification function by decomposing harmful components and malodorous components in the smoke. If a catalyst is supported or if the catalyst itself has a strong (catalytic) action, the purification function will be enhanced.The heating mechanism that heats the detoxifying part will further promote decomposition, etc. and further enhance the purification function.

The adsorption part adsorbs decomposed components (components that are not sufficiently decomposed and, in some cases, undecomposed components) and performs a purification function.

The dust removal section functions to remove cigarette soot and dust. Therefore, deterioration of the functions of the detoxifying part and the adsorption part due to tobacco smoke and dust is prevented.
