Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ashtray, and more particularly to an ashtray equipped with a smoke combustion device for collecting smoke emitted from sized cigarettes placed in the ashtray and discharging it to the atmosphere in a purified state. .

The smoke emitted from cigarettes placed on an ashtray or discarded in an ashtray contains fine particles (solid particles and liquid particles) that have not been completely combusted, and also contains carbon monoxide (CO). , hydrocarbons (HC), are present in concentrations of several thousand (p, p, m).

When this smoke fills a closed room, it is not only unpleasant and harmful to the people living there, but also the fine particles in the smoke, especially tar, adhere to the ceiling and side walls of the room, causing contamination. .

Particularly in recent years, as indoor rooms have become more and more airtight, the negative effects of these on humans are enormous. Provide a sanitary ashtray.

In the past, many devices have been proposed that cause the smoke to rise higher than a person's head in a room, from the viewpoint that people feel particularly uncomfortable when they are near an ashtray containing a lit cigarette.

However, these devices did not purify the smoke itself.

Therefore, harmful particles and harmful substances in the smoke float in the indoor air, eventually descending into the breathing area below and being inhaled by the people in the room.

As another conventional example, a method has been proposed in which harmful particles and harmful substances generated from cigarettes on an ashtray are sucked in by a fan and absorbed and purified through an activated carbon adsorbent.

However, although this method has sufficient ability to purify smoke, since it uses an adsorbent, its absorption capacity is limited and the absorbent needs to be replaced.

In addition, it is difficult to apply smoke to the adsorbent at room temperature without using a fan due to the pressure loss of the adsorbent.
A major drawback is that forced suction is performed by the fan.

The fan noise caused by this is also a drawback that cannot be ignored.

In addition to these two methods, a method using flame combustion has also been proposed.

In this method, cigarette smoke emitted from the top of the ashtray is collected by a skirt-shaped collection tube, and a flame-burning combustion section is installed at the top of the collection tube, and the collected smoke comes into contact with the flame inside the combustion section. The structure is such that when the smoke comes into contact with the flame, the unburned cigarette smoke is completely combusted by the flame.

Although this method is effective, it has the disadvantage that it takes time and effort to change fuel for flame combustion.

The present invention eliminates the drawbacks of conventional ashtrays and provides an ashtray that can continuously purify and discharge harmful substances to the human body generated from placed cigarettes and harmful substances that pollute the room without any particular effort. This is what I am trying to do.

In other words, the present invention provides a smoke combustion device that efficiently collects smoke generated from cigarettes placed in an ashtray and discharges it through a layer of catalyst that can oxidize and purify harmful components such as carbon monoxide and hydrocarbons. The aim is to provide an ashtray with a

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an ashtray with a smoke combustion device according to the first embodiment of the present invention, FIG. 2 is a vertical sectional view taken along the line x-x', and FIG. be.

*; In Figures 1 to 3, 1 is an ashtray, 2 is a covering tube, and 3 is a cigarette holder of the ashtray 1 with a lit cigarette placed in the mouth 4.

The covering tube 2 has an open structure at both upper and lower end surfaces in order to efficiently collect smoke generated from the cigarettes 3 placed in the ashtray 51 and release it into the atmosphere.

The covering cylinder 2 is not limited to the cylindrical structure shown in the figure, but can take other shapes corresponding to the shape of the ashtray 1, and is not particularly limited.

Inside the covering tube 2, a catalyst layer section 7 containing a catalyst body 5 and a heat insulating member 6, a smoke trapping section 8, and a heater 9 are installed in an intermediate section between these sections.

It is preferable that the smoke collecting section 8 at the lower part of the covering tube 2 has a wide opening area in the form of a skirt so that smoke can be collected efficiently.

At the top of the covering tube 2, there is a top plate lid 1 provided with a gas discharge hole 10.
1 is provided.

The top plate lid 11 has the role of preventing the catalyst body 5 from being contaminated from the outside, and it is desirable that the opening area of the gas discharge hole 10 be a sufficient amount to balance this purpose.

Furthermore, the covering tube 2 is supported by a support column 12 provided at the center of the ashtray 1 and a support base 13 connected to the support column 12.
As shown in FIG. 3, it is preferable to place it so that it can be freely attached and detached.

If the covering tube 2 can be easily removed, the ashtray 1 can be cleaned easily.

Further, it is convenient because the catalyst body 5 provided inside can be replaced extremely easily.

In the above configuration, the smoke from the cigarette 3 placed in the ashtray 1 is caused by the heater 9 to generate an upward draft (draft effect) in the covering tube 2, so that the smoke is guided upward through the smoke collection section 8. become.

Here, the smoke of the cigarette 3 comes into direct contact with the catalyst body 5 heated by the heater 9.

The catalyst body 5 completely burns the unburned gas.

The complete combustion referred to here means that the oxidation reaction is carried out using a gas phase oxidation catalyst.

For example, harmful substances such as carbon monoxide (CO) and hydrocarbons (HmCn) are rendered harmless through the following reaction.

The above reaction is the same as the normal complete combustion equation in terms of combustion, but by using the catalyst 5, this reaction can proceed at a lower temperature range and at a faster reaction rate, resulting in complete combustion through catalytic combustion. be.

The catalyst body 5 used is a noble metal (for example, platinum (P
t ), palladium (Pd), etc.) or metal oxides (
For example, a catalyst body 5 based on MnO2-based, Cu2O-based, Co2O3-based, etc. is effective.

As for the shape of the catalyst body 5, it is possible to use any shape such as spherical, pellet, or honeycomb shape depending on the pressure loss.
Taking other factors into consideration, the spherical and pellet-like shapes are used in the case of natural ventilation as in the present invention (natural ventilation is used as opposed to forced ventilation using a fan, etc.).

It has disadvantages in that the resistance in the catalyst layer portion γ is large and increases pressure loss, and there is also a certain limit to the amount of catalyst that can be used.

On this point, in honeycomb-shaped molded products, the opening area of the catalyst can be easily changed by adjusting the number of pores or changing the size of the pores without changing the amount of catalyst, which can reduce pressure loss. is possible.

However, when using a catalyst with excellent catalytic performance, it is possible to reduce the amount of catalyst, and the shape of the catalyst body 5 has little effect (spherical or pellet-shaped catalysts can also be used satisfactorily).

In order to carry out the present invention efficiently, in addition to the shape of the catalyst, the capacity of the heater 9 provided below the catalyst layer may also be a factor.

This is because the structure is such that the smoke of the cigarette 3 is passed through the catalyst layer part 7 by the upward air current (draft effect) generated by the heater 9, and the larger the heater capacity is, the better the upward air flow is.

In addition, the heater 9 also has the purpose of improving catalyst performance, and since the purification performance of gas phase oxidation catalysts usually improves as the catalyst temperature increases, from this point of view as well, the larger the heater capacity, the better.

However, when considering safety and marketability,
In view of the lifespan of the catalyst body 5 if the temperature of the catalyst layer becomes too high, it is recommended that the heater 9 has an appropriate capacity, and this should be carefully considered along with the configuration of the device.

Although various shapes can be considered for the heater 9, it is most desirable to have a shape that has a small pressure loss and can maintain a uniform catalyst temperature.

The catalyst body 5 in the catalyst layer section 7 is supported by a wire mesh net 14 at the lowest stage, and the second and third stage catalyst layers are fixed by a ring 15.

The smoke trapping part 8, the pillar 12, and the support stand 13 of the covering tube 2 are made of synthetic resin or a synthetic resin coating.

That is, the smoke from the cigarette 3 generated on the ashtray 1 is transferred to the catalyst 5.
The coating tube 2, the pillar 12, and the support base 13 are treated with a synthetic resin (for example, Teflon, etc.) that does not have an affinity for tar and the like in the parts that come into contact with the coating tube 2, the support column 12, and the support base 13 before being purified.

In the case of other metals, etc., they have a better affinity than Teflon, etc., and therefore have the disadvantage that they are more likely to be contaminated with tar or the like.

Reference numeral 16 denotes a power cord that passes through the hollow part of the column 7 and the ashtray 5, and is connected to the heater 9.

4 to 6 show a second embodiment of the present invention, and the same parts as in the first embodiment are given the same reference numerals.

From a design standpoint, the second embodiment provides a configuration that can be used as interior decoration to enhance marketability.

Various devices are sold as interior decorations, and many of them utilize light illumination.

Among these, the present invention makes good use of the principle of rotation due to rising air currents, such as a running horse light.

Explaining according to FIGS. 4 to 6, a running light 17 is provided on the upper part of the smoke combustion device of the present invention.

Reference numeral 18 denotes a transparent glass cylinder, and the top plate lid 11 of this cylinder has a gas discharge hole 10.

There is a rod 19 in the center of the top plate lid 11 to fix a blade 20, and the blade 20 rotates around a fulcrum 21 by the rising airflow generated by the heater 9.
is fixed, and the film 22 rotates inside the transparent glass tube 18 as the blade rotates 200 times.

23 is the light bulb of Soumato 17.

Associated with these are an intermediate switch 24, a cigarette ignition switch 25, a variable resistor 26, and a heater 90 for heating the catalyst.
A safety device (thermostat) 27 is wired as shown in FIG. 6, and a cigarette ignition heater 28 can also be attached.

The ashtray with a smoke combustion device of the present invention can fully contribute to the decoration of the room. Cigarette smoke can be cleaned by using the smoke combustion device, and it has an excellent effect of rapidly reducing the harmful effects on the human body and indoor pollution. It is something that plays.
