CONSTITUTION:The container 10 has double-walled side wall comprising the inner cylinder 12 and the outer cylinder 14 to prevent the direct conduction of the fumigation heat. The fumigating chemical 20 is filled in the container 10. A piezoelectric element 24 and a pair of discharge electrodes 28 are attached to the center part of the top plate 18 of the container, and a rod-shaped ignition powder 30 is placed in a manner to fill the gap between the electrodes 28 and extend through the top plate 18. When the button 26 is pushed down, a high tension is generated by the piezoelectric element 24, the top of the powder 30 is ignited by the spark generated between the electrodes 28, the combustion of the powder is propagated gradually to the lower part of the powder 30, the fumigant is ignited, and the fume is discharged from the hole 22 of the top plate 18. The top of the rod-shaped powder 30 is composed of an ignition powder having low ignition temperature, and the following part of the rod is composed of powder having low rate of combustion.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a smoking material, and more particularly to a smoking material with an improved mechanism for igniting a smoking agent.

In general, a smoking material is constructed by filling a container made of synthetic resin or the like with a smoking agent and providing a mechanism for igniting the agent.

Conventionally, a flammable rod-like body similar to a phosphorescent rod has been used as this ignition mechanism, but the ignition operation is complicated and there is a risk of ignition failure in high humidity.

In recent years, as an improved version of this, a device is being used in which the gunpowder for igniting the smoke agent is placed close to the smoke agent, and a filament is provided to ignite the gunpowder. In other words, connect a dry battery to this fixture and turn on the electricity.
The gunpowder is ignited by the generated Joule heat.

However, in this battery/filament type,
The smoking material itself and the dry battery must be prepared as a set, which increases the complexity of managing the manufacturing and distribution system such as manufacturing, storage, and sales. Furthermore, if the dry cell battery deteriorates due to natural discharge, there is the inconvenience of using the battery in that the dry cell battery must be purchased separately.

An object of the present invention is to solve the problems of the prior art described above, and to provide a smoking material that is extremely simple to ignite and is equipped with an ignition mechanism that does not deteriorate over time.

The smoking material of the present invention is a smoking material formed by filling a container with a smoking agent, in which a gunpowder for igniting the smoke agent is placed close to the smoke agent, and a piezoelectric igniter for igniting the gunpowder is installed. It is characterized by the fact that it has been provided.

The present invention will be described in further detail below with reference to embodiments shown in the drawings.

FIG. 1 is a longitudinal view of a smoking material according to an embodiment of the present invention, FIG. 2 is a perspective view of the same (however, the lid 34, which will be described later, is removed), and FIG. 3 is a summary of FIG. 1. It is an enlarged view of the part.

Reference numeral 10 denotes a container, and the side portion thereof has a double structure of an inner cylinder 12 and an outer cylinder 14, and is configured so that heat during smoking is not directly transmitted to the outside. The inner cylinder 12 has a bottom plate 16 and a top plate 1.
8 is provided, and the inside thereof is filled with a smoking agent 20. A large number of holes 22 are bored in the top plate 18 so that smoke can be led out to the outside.

The mechanism for igniting the smoke agent 20 will now be described with reference to FIG. 3. Approximately at the center of the top plate 18, there are provided a piezoelectric element 24, a push button 26 for applying an impact to the piezoelectric element, and a pair of discharge electrodes 2'8 for discharging with a high voltage generated by the applied impact. There is. A rod-shaped gunpowder 3o is arranged to penetrate through the top plate 18 so as to fill the gear jib of the discharge electrode 28. The top of the gunpowder 30 is a discharge electrode 28
It is made of gunpowder with a low ignition temperature so that it can be easily ignited by the sparks generated in between.
The lower part d1 is made of gunpowder with a low burning speed in order to moderate the propagation of flame. - When push button 26 is pressed, element 2
A high voltage is generated at 4, causing 1 to occur several times between the electrodes 28, and the top of the gunpowder 60 is ignited. The flame gradually moves to the lower part of the gunpowder 30, and the smoke agent 20 is ignited. In the figure, 32 is an element cover, and 64 is a lid of the container 10.

To use the smoking material constructed in this manner, it is only necessary to remove the lid 34 (the state shown in FIG. 2) and then press the push button 26, making the operation extremely simple.

Furthermore, since a piezoelectric element is used, there is no deterioration over time due to natural discharge, as is the case with battery-powered devices. Furthermore, since spark ignition is performed by a piezoelectric element, ignition is easy even when the humidity in the air is high, and there is no ignition failure due to moisture, which is the case with conventional phosphor-type lenses.

In the embodiment described above, the piezoelectric device is provided at the top of the container and is covered by the lid 34 when stored before use. Therefore, there is no risk of misuse such as accidentally pressing the button and igniting the ignition. However, in the present invention, the ξ piezoelectric device may be provided in other locations, such as the bottom or side of the container. Also good.

FIG. 4 is a longitudinal sectional view of a smoking material according to a different embodiment of the present invention, in which the mounting position of the push button has been changed.

This smoking material is made by placing the piezoelectric element 66 horizontally and placing the piezoelectric element 24 horizontally.
A rod 40 is provided with a buttonhole 8 attached to the tip in order to apply an impact to the rod. The element 36 is electrically connected to the discharge electrode 28 via a lead wire.

The smoking material of this example is also easy to ignite and does not deteriorate over time.

Particularly in this embodiment, as shown in FIG. 5, which is an enlarged view of the portion shown in FIG.
It is inserted into this notch 42 by penetrating through it. The gap 1 between the container 10 and the button 38 is selected so that the button 38 cannot be pushed in unless the lid 54 is removed.

Therefore, even if this button 58 is touched when not in use, such as during transportation, the button will not be pushed in, and there is no risk of misuse. Reference numeral 44 in FIG. 4 is a support for supporting the element 66. The rest of the structure is similar to that of the embodiment shown in FIGS. 1 to 3, and the same or equivalent members are designated by the same reference numerals.

As detailed above, the smoking material of the present invention uses a piezoelectric device for the ignition mechanism, and the ignition operation is extremely simple, and there is no deterioration over time, and long-term storage is possible.
