FIG. 1 is a perspective view showing a state in which the writer body 1 is attached to the writer head 20, and FIG. 2 is a side view. FIG. 3 shows only the writer body 1 removed from the writer head 20. The writer head 20 has an inverted conical opening 23 into which a cigarette is inserted, and a light emitting diode 24 and a light receiving element 25, which face each other with the center line in between, are mounted on the conical wall surface. The light emitted by 7 is received by the light receiving element 8 (photo sensor is on). When the tip of the cigarette is inserted into the opening 23 for igniting the cigarette, the light emitted from the light emitting diode 7 is blocked by the cigarette, and the light receiving element 8 does not receive the light (the photo sensor is off).

The writer head 20 has a side opening 21 for inserting the writer main body 1 with the lower end of the opening 23 opened. The inner wall surface of the side opening 21 has a rail-shaped ridge on the side surface of the writer main body 1. The fitting grooves 22a and 22b are cut. On the back surface of the writer head 20, an instrument board on the front of the driver's seat of the automobile and a suction cup 28 for fixing the writer head 20 to a general vertical plane are fixed. An object detection circuit (signal processing circuit) 26 (FIG. 4) to which a light emitting diode 24 and a light receiving element 25 are connected is provided inside the writer head 20, and a power line and a signal line of this object detection circuit 26. Are connected to the electrical connection terminal 27 (FIG. 4). The electrical connection terminal 27 is on the ceiling surface inside the opening 21.

An electrical connection terminal 3 (FIG. 3) is provided on the upper end surface of the writer body 1, and when the writer body 1 is mounted on the writer head 20 as shown in FIGS. The electrical connection terminal 3 of the writer body 1 is aligned with and in contact with the electrical connection terminal 27. The writer body 1 is separated from the writer head 20 by pulling the writer body 1 out of the opening 21 along the grooves 22a and 22b.

FIG. 4 shows a state in which the writer body 1 is attached to the writer head 20 as shown in FIGS. 1 and 2.
The connection relation of the electric circuit elements inside them is shown. The writer main body 1 has a cigarette insertion hole 2 aligned with the opening 23 of the head 20 in a state where the writer main body 1 is attached to the writer head 20, and an electric heating element 6 for direct ignition is provided below the bottom opening. Small batteries 7a and 7b are housed in the writer body 1, and these batteries 7a and 7b and the electric heating element 6 are
The switch circuit 4 is interposed between the two. If the light receiving element 25 receives light (the photo sensor is on) while the object detection circuit 26 is energizing the light emitting diode 24,
A low-level L signal (switch-off instruction signal) which means no smoking is given to the switch circuit 8 and the light-receiving element 25 does not receive light when the light-emitting diode 24 is energized (photosensor is off). , A high-level H signal (switch-on instruction signal), which means that there is a cigarette, is supplied to the switch circuit 8.

The switch circuit 8 includes an object detection circuit 26,
When a low level L signal (switch-off instruction signal) is being issued, the switching element (inside the circuit 8) connected to the energization heating element 6 is turned off (non-energized), but the high level H When a signal (switch-on instruction signal) is given, the switching element is turned on (energized) and the energization heating element 6 is energized. As a result, the energization heating element 6 becomes high temperature due to the heat generated by the jul and the temperature of the air that has entered the main body 1 through the ventilation port 5 becomes high and the opening 23 from the lower bottom opening of the insertion hole 2 opens.
And the lower end of the cigarette is ignited. However, when the energization of the energization heating element 6 is started, the timer 9
Is triggered and the energization continues for a set time T1 or more, the time is over when the set time T1 elapses, and a switch-off instruction signal is given to the switch circuit 8.
As a result, the switch circuit 8 is turned off (energization of the energization heating element 6 and the timer 9 is cut off).

On the other hand, there is a thermistor 10 at a side slightly above the bottom opening of the tobacco insertion hole 2, and the temperature detection circuit 11 connected to the thermistor 10 detects the temperature detected by the thermistor 10. Low level L (buzzer off signal) when the tip of the cigarette is below the temperature at which it is ignited by the electric heating element 6.
Is generated, a high level H (buzzer-on instruction signal) is generated and applied to the switch circuit 12. The switch circuit 12 turns off the buzzer driver 13 (deenergizes / does not activate the buzzer) when the temperature detection circuit 11 issues a low level L signal (buzzer off instruction signal). However, when a high level H signal (buzzer-on instruction signal) is given, the buzzer driver 13 is turned on (energization /
The buzzer 14 is activated by setting the buzzer to activate. The buzzer sound goes out of the main body 1 through the eyelet 4 (FIG. 3). However, when the timer 15 is triggered when the energization of the buzzer driver 13 is started and the energization continues for the set time T2 or more, the time is over when the set time T2 elapses and the switch circuit 12 is turned on. A switch-off instruction signal is given, whereby the switch circuit 12 is turned off (energization to the buzzer driver 13 and the timer 15 is cut off).
To do. Even when the cigarette is extracted from the opening 23 and the output of the object detection circuit 26 becomes the low level L, the switch circuit 12 is turned off by the signal of the low level L (energization to the buzzer driver 13 and the timer 15 is cut off). ) Do.

FIG. 5 shows the components of the electric circuit shown in FIG.
The output signal is shown. The writer body 1 is attached to the writer head 20,
When mounted as shown in FIGS. 1 and 2, the writer head 2
The object detection circuit 26 of 0 is connected to the batteries 7a and 7b through the electric connection terminals 27 and 3, so that the light emitting diode 24 is turned on and the light receiving element 25 receives light. When the writer user inserts the tip of the cigarette into the opening 23 and inserts it into the lower bottom hole of the insertion hole of the writer body 1, the light receiving element 25 does not receive light and the object detection circuit 26 operates in conjunction with this and the high level H is detected. A signal (switch-on instruction signal) is applied to the switch circuit 8, whereby the switch circuit 8 energizes the energization heating element 6, and the timer 9 is triggered accordingly and the timed operation is started.

When the tip of the cigarette is ignited by the heat of the electric heating element 6, the thermistor 10 detects a high temperature and the temperature detection circuit 11 gives a high level H (buzzer on instruction signal) to the switch circuit 12, Causes the buzzer 14 to ring and the timer 15 to be triggered. When the user pulls out the cigarette through the opening 23, the light receiving element 25 receives the light accordingly, and the object detection circuit 26 operates at a low level L in conjunction with this.
Signal (switch-off instruction signal) is given to the switch circuit 8 and the switch circuit 12, whereby the switch circuit 8
Shuts off the energization of the energization heating element 6, stops the energization of the timer 5, and stops the ringing of the buzzer 14 and the energization of the timer 15.

If the user does not pull out the cigarette through the opening 23 even though the buzzer 14 is ringing, first, the timer 9 switches over after the time T1 from the start of energization of the heating element 6. Turn off the circuit 8
Is stopped, and the timer 9 is also stopped.
After that, the timer 15 starts T2 after the start of the buzzer 14 ringing.
Turns off the switch circuit 12 to stop the energization of the buzzer driver 13, thereby stopping the energization of the timer 15. That is, the energization of the energization heating element 6 once is limited to T1 at the longest, and the single ringing of the buzzer 14 is limited to T2 at the longest.

As described above, according to the above-described embodiment, when the writer body 1 is not attached to the writer head 20, the head-side electrical connection terminal 27 is not in contact with the writer body-side connection terminal 3. The switch circuit 8 does not energize the energization heating element 6. When the writer main body 1 is attached to the writer head 20, when the cigarette is inserted into the lower opening of the insertion hole 2, the switch circuit 8 causes the energization heating element 6 to operate.
And the heat of the heating element 6 ignites the cigarette. When the user pulls out the cigarette through the insertion hole 2 and the opening 23, the switch circuit 8 disconnects the energization of the energization heating element 6. Therefore,
The energization heating element 6 is energized only for a short time, and the electric energy consumption is saved.

When the cigarette ignites, the temperature of the thermistor 10 rises and the buzzer 14 responds to the temperature rise.
Since the sound is emitted, the user is prompted to pull out the cigarette from the insertion hole 2 and the opening 23, so that the electricity is supplied for the minimum necessary time, and the effect of saving the electric energy consumption is further enhanced.

The above embodiment is of the direct ignition type in which the cigarette is directly ignited by the heat of the electric heating element 6.
The present invention ignites fuel gas with an electric heating element, or
The high-voltage generating circuit intermittently generates electric sparks at the discharge electrode to ignite the fuel gas, and the same can be applied to the adhesive ignition type smoking lighter while igniting the cigarette by the flame or heat of the ignited fuel. ..
