Description

Cigarette lighter of vehicle and its operation control method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette lighter of a vehicle, and in particular, for convenience of a driver or a passenger, a cigarette lighter of a vehicle configured to facilitate the safety of a user while being able to conveniently insert a cigarette without having to unplug the cigarette lighter and to light a cigarette. It relates to the operation control method.

In general, a cigarette lighter 10 is mounted on a right side of a driver's seat as shown in FIG. 1 in a vehicle such as a passenger car so that a driver or a passenger may conveniently attach a cigarette light. As shown in Fig. 2, the cigarette lighter has a structure in which the cigarette lighter plug 20 is inserted into a holder 22 provided with a coil heater. (+) Power terminal is connected to the cylindrical portion of the holder 22 and (-) power terminal is connected to the tip of the holder 22. When using such a cigarette lighter 10, a user presses the cigarette lighter plug 20 inserted in the holder 20 more than presses now. Then, the cylindrical portion of the cigarette lighter plug 20 comes into contact with the positive power supply terminal, and the tip of the cigarette lighter plug 20 comes in contact with the negative power supply terminal to form a closed circuit. This causes the hot plate attached to the tip of the cigar plug 20 to burn off. After a period of time when the soleplate was completely burned out, the user pulled the cigarette lighter plug 20 out of the holder 22 and put a cigarette on the heated soleplate to light a cigarette.

However, this conventional technology has a problem that when a user uses a cigarette lighter, the cigarette lighter plug needs to be unplugged and ignited. Unplugging the cigarette lighter and igniting it not only hassle for the user, but also hinders safe driving.

Accordingly, an object of the present invention is to provide a cigarette lighter and a method of controlling the operation of the vehicle, which can be conveniently inserted to light a cigarette without unplugging the cigarette lighter, while also promoting the safety of the user.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a direct-insert type cigarette lighter according to an embodiment of the present invention, so that it is possible to conveniently insert a cigarette without having to unplug the cigarette lighter as in the past, and to light the cigarette, while also promoting the safety of the user Has a structure to do

Cigarette lighter according to the present invention, the cigarette insertion opening 32 having a guide of the funnel structure for guiding the insertion and insertion of tobacco 30, and a cigarette insertion detection attached to the funnel portion of the cigarette insertion opening 32 to detect the presence of tobacco Sensor 34,36, a delay insertion detection sensor 38 is attached to the funnel portion of the cigarette inlet 32 and detects the human body insertion, and the coil heater 40 is installed on the inner end of the cigarette inlet 32 and generates heat by applying power And a switch 42 for switching the application of power to the coil heater 40 on and off by a predetermined control, and the coil heater 40 being powered on or off based on the presence or absence of cigarette insertion detection of the cigarette insertion sensor 34,36. A control unit for controlling the switch 42 and controlling the switch 42 to cut off power of the coil heater 40 based on the delay insertion detection of the delay insertion detection sensor 38. It consists of 44.

In this configuration, the cigarette insertion sensor 34,36 is an optical sensor composed of the light emitting unit 34 and the light receiving unit 36, the delay sensor 38 is to detect the temperature of the human body according to the delay when the delay, for example, the finger is inserted. It is a temperature sensor.

4 is a control flowchart of the controller 44 of FIG. 3 according to an exemplary embodiment of the present invention, wherein the switch 42 is configured such that power is applied or cut off to the coil heater 40 based on the presence or absence of cigarette insertion detection of the cigarette insertion detection sensors 34 and 36. And the power supply of the coil heater 40 is cut off based on the delay insertion detection of the delay insertion detection sensor 38.

Hereinafter, an operation according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4. The funnel structure of the cigarette insertion opening 32 of FIG. 3 allows a user such as a driver or a passenger to roughly put a cigarette. When the user inserts the cigarette 30 into the cigarette insertion hole 32 in this manner, the light emitted from the light emitting part 34 of the cigarette insertion sensor 34 and 36 attached to the funnel part is blocked by the light receiving part 36. In this case, the controller 44 checks this in step 50 and determines that the cigarette is inserted. When the cigarette is inserted, the controller 44 turns on the switch 42 so that the power supply Vcc is applied to the coil heater 40. Since the coil heater 40 to which the power supply Vcc is applied generates heat, when the cigarette 30 is inserted into the cigarette inlet and outlet 32 for a predetermined time, the cigarette is lit.

Then, the user will remove the cigarette 30 from the cigarette insertion opening 32, so that the light emitted from the light emitting portion 34 of the cigarette insertion sensor 34, 36 is received by the light receiving portion 36. As a result, the controller 44 checks that the cigarette is inserted in step 54 and proceeds to step 56 to turn off the switch 42. The coil heater 40 no longer generates heat.

On the other hand, if the user inserts a finger into the cigarette insertion opening 32 due to carelessness of the user or the curiosity of the younger passenger, the delay sensor attached to the funnel, that is, the temperature sensor 38 immediately detects this and provides it to the controller 44. As shown in step 58 of FIG. 4, the controller 44 checks the delay insertion of the finger as the output signal of the temperature sensor 38 and turns off the switch 42 in step 60. Therefore, the coil heater 40 does not generate heat due to carelessness of the user or curiosity of the younger passenger.

In the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and the claims.

As described above, the direct-insertion type cigarette lighter of the present invention can conveniently insert a cigarette and ignite the cigarette without removing the cigarette lighter plug as in the prior art, and also promote the safety of the user.
