The invention provides an intelligent lighter. The intelligent lighter comprises a shell and a flap arranged above the shell, wherein the upper end of the shell is provided with a lighter. The intelligent lighter is technically characterized in that a control
chip and a power supply which supplies power to the control
chip are formed in the shell; an image probe and a
smoke sensor are formed in the flap; the image probe and the
smoke sensor are connected with the control
chip, respectively; a display screen is arranged on the shell and is connected with the control chip. According to the intelligent lighter, the
smoking behavior of a smoker is detected by virtue of the image probe and the
smoke sensor; and the detection information is transmitted to a single-chip
microcomputer, the single-chip
microcomputer judges whether a user is smoking or not, and counts the smoking number and displays the smoking number by the display screen, so as to exhort the smoker to reduce the smoking amount or quit from smoking. The control chip is further connected with a
clock chip, and a switching button which is connected with the control chip is arranged on the lighter body and is ued for switching the smoking information displayed on the display screen to
clock information, so that a smoker can conveniently look at time, and meanwhile the pressure of the smoker, caused by too much prompt messages related to harmfulness of smoking, is avoided.
