Description

[Detailed explanation of the invention] [Field of the invention] This invention is based on the idea that by burning a chemical, the insecticidal ingredients contained in the chemical are diffused into the air along with the generated smoke, and the insecticidal components are dispersed into the air, such as indoors, houses, etc. , relates to a smoker for exterminating insects such as cockroaches and mites living in a certain space.

[Prior art]

Conventional smokers of this type use an auxiliary agent such as gunpowder to ignite the chemical. However, from the point of view of ignition performance, the above-mentioned auxiliary agent should be one that is as easy to ignite as possible, and therefore requires careful handling from the standpoint of safety. This is what makes it difficult. In addition, depending on the storage conditions, the quality of this adjuvant often changes due to moisture, etc., so careful attention is required in this regard as well.
There is also a limit to how long a product can be used after manufacturing.

Furthermore, when using this smoker, the auxiliary agent must be ignited with a matchstick, etc., which not only requires a troublesome operation, but also causes people to inhale the smoke generated from the auxiliary agent and chemicals when igniting. Hygiene issues have also been pointed out.

[Purpose of invention]

This invention was made to solve these problems with conventional smokers.It not only makes it easier to store and handle during transportation, but also allows for stable storage over a long period of time. To provide a smoker that can be ignited by a simple operation without a person inhaling smoke generated from a chemical.

[Structure and implementation examples of the idea]

Hereinafter, the structure of this invention will be explained in detail with reference to the illustrated embodiment. The smoker according to this invention has a medicine holder 2 containing a medicine 1 and a base 3 on which the holder 2 is placed. The drug holder 2 is provided with an electric heater 4 for igniting the drug 1, and connecting pins 5, 5 electrically connected to the heater 4.
is provided to protrude downward from the bottom surface of the holder 2. On the other hand, the base 3 houses a power source 6, and sockets 7, 7 into which the connecting pins 5, 5 are removably fitted when the drug holder 2 is placed.
is connected to the power source 6. Furthermore, between the power source 6 and the electric heater 4, which are connected via these sockets 7, 7 and the connecting pins 5, 5,
A power cutoff means is provided for cutting off the circuit after the chemical 1 is ignited.

The medicine holder 2 is a cylindrical can-shaped thing, in which a solid medicine 1 is stored, and in each of the illustrated embodiments, an electric heater 4 is attached so as to be in contact with the lower surface of this medicine 1. . For the power source 6, a dry cell battery or the like can be used. For example, in the case of a household smoker used to exterminate ticks, cockroaches, etc., two commercially available manganese dry cell batteries connected in series (3V) can be used. It has been confirmed that it is possible to ignite chemical agent 1 in less than one minute by using .

In the embodiments shown in FIGS. 1 and 2, a switching circuit 8 equipped with a timer is used as a power cutoff means. For this switching circuit 8, a non-contact circuit using a transistor and a Zener diode as shown in FIG. 2 can be used, for example, and this is housed in the base 3 together with the power supply 6.
After the time necessary for igniting the chemical 1 has elapsed since the electric heater 4 started being energized, the circuit is opened.

On the other hand, in the embodiment shown in FIGS. 3 and 4, a low melting point conductor 9 is used as the power cutoff means. That is, this low melting point conductor 9 is made of solder or the like having a melting point that is easily melted by the combustion heat of the chemical 1, and in the case shown in the figure, it is provided in contact with the upper surface of the chemical 1, and Electric heater 4 is connected to connecting pins 5, 5 through this.

As is already clear from the above explanation, this smoker is used by placing the drug holder 2 containing the drug 1 on the base 3 and fitting the connecting pins 5, 5 into the sockets 7, 7. . Then, the electric heater 4 generates heat by the power source 6, and a part of the medicine 1 in contact with it is gradually heated, and the medicine 1 is ignited from that part. After this, in the embodiments of FIGS. 1 and 2, after a predetermined time has elapsed in the switching circuit 8, and in the embodiments of FIGS. 3 and 4, the low melting point conductor 9 When the electric heaters 4 are fused by heat, the power supply to the electric heaters 4 is stopped.

[Effect of idea]

As described above, with the smoker of this invention, there is no need to provide gunpowder or the like as an auxiliary agent for igniting the chemical 1, making it easier to handle, and stably maintaining the specified ignition performance over a long period of time. can do. In addition, the chemical holder 2 can be ignited simply by setting it on the base 3, and by leaving the smoker between setting and igniting, the person can avoid inhaling the smoke generated from the chemical 1. It will also help you live.
