Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

One drags four bands button cigar lighter data line, as shown in fig. 1, including heater 10, MCU controller 20 and data connector 30, wherein data connector 30 is used for with the vehicle on all kinds of power ports peg graft to for the cigar lighter provides the power, MCU controller 20 control cigar lighter work switching, heater 10 are used for heating the tobacco, and it often is the heating resistor silk, makes the tobacco ignite through generating heat. For the switching of better control cigar lighter, the utility model discloses still include button K1 and switch tube Q1, button K1 control MCU controller 20 sends PWM control signal control switch tube Q1's break-make, switch tube Q1 is connected with heater 10 electricity to control heater 10 generates heat and ignites the tobacco, and simultaneously, it is improper to avoid the user to use button K, or because other factors such as curiosity, press the button for a long time, or the button itself damages because the part is used for a long time, cause the heater to turn-off, MCU controller 20 has overtime detection module, detect button K1 on-time overlength when MCU controller 20, control switch tube Q1 turns-off, thereby make heater 10 extinguish, avoid the heater to be in the state of generating heat for a long time.

Specifically, switch tube Q1 links to each other with MCU controller 20 pin 6, button K1 links to each other with MCU controller 20 pin 4 and pin 5, and after MCU controller 20 pin 4 and pin 5 received button K1's trigger signal, sent PWM control signal to pin 6 to control switch tube Q1's break-make.

As further optimization improvement, in order to prevent that MCU controller 20 also became invalid simultaneously with button K and lead to heater 10 to generate heat the time overlength, the utility model discloses still include protection device PTC fuse R1, PTC fuse R1 is connected with data connection mouth 30 electricity, and when the heat of cigar lighter exceeded protection device PTC fuse R1's overheat point, PTC fuse R1 can break off power supply circuit, resumes after the reduction of PCB board temperature, continued use. Meanwhile, the PTC fuse R1 also has an overcurrent protection function, and when a short circuit is caused due to a fault, for example, two rings of heating wire rings are deformed and dislocated to be connected together to cause the current to exceed a normal range, the PTC fuse R1 can automatically cut off the power supply. When the short-circuit fault is eliminated, the PTC fuse R1 can be electrified to restore normal operation. Therefore, the heating wire 10 is not always in a heating state due to faults, overheating and overcurrent protection can be achieved for the circuit, and safe use of the cigarette lighter is guaranteed.

As a further optimization and improvement, in order to facilitate a user to determine the power-on state of the cigarette lighter, the cigarette lighter charging circuit includes a light-emitting diode D1, the light-emitting diode D1 is electrically connected to the PTC fuse R1, and when the PTC fuse R1 is turned on, the light-emitting diode D1 is turned on, and at this time, a warning lamp is turned on to prompt the user that the cigarette lighter is in the power-on state.

Meanwhile, in order to facilitate a user to determine the heating state of the heater 10, the 1 st pin of the MCU controller 20 is connected to a light emitting diode D2, and when the MCU controller 20 sends a PWM control signal through the 6 th pin. The 1 st pin is conducted, the light emitting diode D2 is in a conducting state, and then a user can determine whether the heating wire 10 is in a heating state through the on-off of the light emitting diode D2.
