Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Same or like component is indicated with identical label in different figures；In addition it is understood that such as " first " in text,
" second ", " third ", "upper", "lower", "front", "rear", "inner", "outside", " end ", " portion ", " section ", " width ", " thickness ", " area "
Etc. and similar term be only convenient for observer with reference to constructing and be only used for help to describe the present invention in figure, be not to
The restriction of invention.
Please refer to Fig. 1-3, the present invention provides a kind of technical solution: the touch electronics of the novel control mode of one kind lights a cigarette
Device, including integrated chip, the T foot of integrated chip be electrically connected with the concatenated touch point of R2 resistance and capacitor C3, at this
Touch point be used to control the working condition of heating wire in electronic cigarette lighter；One end of capacitor C3 and GND are electrically connected, and are integrated
Chip EN foot is in series with a switch S1, and one end of switch S1 and GND are electrically connected, and the switch S1 at this can control touch point ten
Divide the switch that can be used；The VDD foot of integrated chip and the VDD foot of charging port are electrically connected, the OUT foot and hair of integrated chip
Heated filament series connection, the other end and GND of heating wire are electrically connected, and heating wire can generate heat when being powered, and then light cigarette；
