Description

[Detailed Description of the Invention] The present invention relates to a cigarette lighter installed in automobiles and the like.

Automotive cigarette lighters are usually nichrome wire heaters that pop out automatically when they become red-hot, but the passenger must use them to light a cigarette by hand.

For this reason, it is dangerous for a driver to use a cigarette lighter while driving, as it may lead to situations such as not paying attention to the road ahead.

On the other hand, some devices have a heater placed deep inside the hole into which the cigarette is inserted, and automatically light the inserted cigarette, but this does not result in good ignition and often results in uneven ignition. or cigarettes may burn onto the heater.
At present, it is not generally put into practical use.

The present invention is intended to solve these problems, and provides a cigarette lighter that can achieve extremely good ignition conditions by pumping a small amount of air at the same time as ignition.

An embodiment of this invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, a vehicle instrument panel 1
The ignition tube 2, which is attached to a vehicle, has a trumpet-shaped insertion opening 3 at its tip.

The insertion opening 3 is formed to have a diameter that allows the cigarette A to fit therein almost tightly.

The ignition tube 2 is rotatably supported by a guide tube 4 of the instrument panel 1.

The interior of the ignition tube 2 is partitioned into a nearly hermetically sealed space 7 by an insulator 5, and a heater (heating element) 8 made of nichrome wire or the like is attached to a position opposite the insertion opening 3 described above.

Current from a power source 9 such as a battery is supplied to the heater 8 via a switch 10, and the heater 8 becomes red hot when the switch 10 is turned on.

Reference numeral 11 indicates a conducting wire for this purpose.

A bellows 12 as an air blower is attached to the outside of the ignition cylinder 2, and a predetermined amount of air is forced into the space 7 through the small hole 13 at the time of ignition.

A weight 14 is provided at the free end of the bellows 12, and when the bellows 12 is in the lower position as shown in FIG. 1, the weight 14 extends the bellows 12, causing the ignition cylinder 2 to rotate as shown in FIG. When the bellows 12 is positioned upward, the bellows 12 is compressed and air is blown into the space 7.

With this configuration, when it is time to light the cigarette A, the cigarette A is inserted through the trumpet-shaped insertion opening 3 until it hits the heater 8, and the switch 10 is turned on.

Eventually, the heater 8 becomes red hot and a portion of the cigarette A ignites, but unlike the way a person ignites the cigarette while smoking, the cigarette does not ignite smoothly.

Then, when the ignition tube 2 is rotated approximately half a turn, the bellows 12 is positioned directly above, and air that has been properly squeezed through the small hole 13 is sent into the space 7 into which the cigarette A is inserted.

Since space 7 is sealed, this compressed air is
It flows through the interior of the tube and towards the mouthpiece, creating a state similar to that of lighting a fire while smoking.

In this way, very good ignition conditions are automatically achieved.

In this case, instead of blowing air with a blower, it is possible to use a suction device to suck air from the mouthpiece, but if this is done, cigarette tar, tar, etc. will accumulate on the suction device, impairing the proper operation of the device. Although this may be easy, since the air is sent out in the opposite direction by the blower, such inconvenience does not occur at all.

As described above, according to the present invention, the bellows is used to ignite the ignition tube while blowing air into the ignition cylinder, so the ignition can be automatically and reliably ignited.Moreover, the device is simple and the ignition operation is easy. be.

Claims (1)

[Scope of utility model registration request] A sealed space is formed inside the ignition tube, which has an insertion port with a diameter that approximately matches the diameter of the cigarette, and a heater is mounted facing the insertion port, while the ignition tube is rotatably supported. A cigarette lighter characterized in that a bellows is attached to the outside of the cigarette lighter, a weight is provided at the free end of the bellows, and the inside of the bellows and the internal space of the ignition tube are communicated through a small hole.
