[Detailed Description of the Invention] The present invention aims to accurately test the flammability of chairs, beds, bedding futons, blankets, sheets, etc. using a cigarette using a tester. This invention relates to an artificial cigarette type combustion tester consisting of a heater that produces combustion and its control circuit.

In the conventional test method, a lit cigarette was placed on, for example, a chair, and the degree of combustion was examined to test the combustibility of the specimen. When igniting a cigarette, the temperature at which the cigarette burns differs depending on the surrounding air humidity, the heat capacity of the cigarette itself, and the amount of heat generated by combustion.
Not only are test results highly variable, but cigarettes sometimes go out during the test.

The present invention eliminates these conventional drawbacks, and uses an electric heater similar to the shape of a cigarette, for example, a silicon carbide (carborundum) rod with four or more drawers, without using tobacco as an ignition source. A wire is installed, and a switch that responds to a timer turns on electricity in sequence, heating accurately from the end to reproduce the combustion of a cigarette. Furthermore, by making the applied current variable, it is possible to adjust the temperature and test at a predetermined temperature.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the ignition heater, and FIG. 2 shows its control circuit diagram. In FIG. 1, the resistance heating element 1 is, for example, a silicon carbide (carborundum) rod, and its length and thickness are approximately the same as that of a cigarette, and the lead wires 2, 3, 4,
5, 6, and 7 are provided separately. Although the lead wire is shown wrapped around the resistance heating element 1 in the figure, it may be fastened in other ways, such as with a band. Use a metal that does not easily oxidize, such as titanium, platinum, or nichrome wire, for the lead wire. As shown in the figure, when dividing into 5 parts by drawing lines, if each divided part is individually energized with 7V, the temperature of the resistance heating element will be approximately 600°C. If the voltage is lowered to 4.2V, the temperature can be set to approximately 300℃.

This is done by the control circuit shown in the figure. In FIG. 2, relays RY1, RY2, RY3, RY4, and RY5 are switched at time intervals set by time switch 9. The transformer 10 has an input voltage of 100V from 0 to
There is a tap that converts to 12V. Since each relay is connected to the lead wire of the ignition heater 8, heating can be performed sequentially for each division.

The test method is to first investigate the relationship between transformer voltage and temperature and then select a predetermined temperature. For example, a temperature of 600°C can be obtained with an input of 60V and an output of 7V. Place the heater on top of the test sample. It takes about 20 minutes for a cigarette to burn out, so set the time switch at 4 minute intervals, which is 1/5 of that time. When you turn on the switch,
One end of the heater is heated, and after 4 minutes the next section is heated, and so on, until the cigarette continues to burn. Heating is completed in 20 minutes, and a judgment is made by examining how the test sample burns.

The left diagram in FIG. 5 shows the state before the start of energization, and the center diagram shows the state immediately after the heater was removed after 20 minutes of energization, but the combustion carbonization part 15 remains and is smoldering. The figure on the right shows flame 1 after that.

On the other hand, although tests were conducted using conventional cigarettes, it was not possible to always obtain consistent conditions due to variations in the cigarette itself and differences in surrounding conditions, and not only was the reproducibility poor, but the cigarettes caught fire during the process. It often disappears.
