The present invention relates to a cigarette lighter and, more particularly, to a cigarette lighter equipped with an alarm.
U.S. Pat. No. 5,228,848 discloses a conventional cigarette lighter 10 with message. The cigarette lighter 10 includes a lever 40 that can be pressed in order to ignite and a switch 50 that can be moved in order to provide a message. Whenever the lever 40 is pressed, the switch 50 is moved. That is, every attempt to ignite causes the message to be played once. It often happens that several attempts are made before ignition is achieved. Repeating of the message is annoying.
The present invention is therefore intended to obviate or at least alleviate the problem encountered in the prior art.
It is an objective of the present invention to provide a cigarette lighter equipped with an alarm for providing only one round of a message every time the cigarette lighter is opened for use.
According to the present invention, a cigarette lighter includes a reservoir for storing fuel and a head formed on the reservoir. Moreover, the cigarette lighter includes a valve for releasing the fuel from the reservoir, a nozzle put in the head for spraying the fuel from the valve, an ignition device for igniting the fuel sprayed from the nozzle, a cover for covering the head and an alarm for providing only one round of a message every time the cover is lifted.
Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the attached drawings.

The ignition device 15 includes a body 24, a button 26 in the form of a plunger extending into the body 24 and an electrode 28 extending from the body 24 to the vicinity of the nozzle 16. In the body 24 is arranged a circuit (not shown) from which the electrode 28 extends. When the button 26 is pushed, a voltage is produced by the circuit. Thus, an electric arc appears between the electrode 28 and the nozzle 16.
On the button 26 is installed an external button 23 for contact with a user's thumb. A rod 25 extends from the external button 23.
The cover 21 includes two ears 42 extending from a side. A collar 44 is installed on the head 11. The collar 44 includes two ears 46 extending from a side. The ears 42 are pivotally connected with the ears 46 by a pin 50. The cover 21 defines, in an edge, a hole 27 in which the rod 25 can be fit so as to keep the cover 21 closing the collar 44. A torque spring 29 is installed on the pin 50 for snap-opening the cover 21.
The alarm 30 includes a switch 31 installed on the collar 44 between the ears 46, a circuit board 35 put in the container 40 and a wire 36 leading to the switch 31 from the circuit board 35. A chip 32, a speaker 33 and a battery 34 are installed on the circuit board 35. The chip 32 and the speaker 33 are powered by the battery 34. When the circuit board 35 is put in the container 40, the speaker 33 is aligned with an aperture (not numbered) that is defined in the container 40 and is covered by a screen 19.
