The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1, be the structural representation of the electronic cigarette of the utility model embodiment.
In the utility model embodiment, electronic cigarette comprises microcontroller 10, supplying cell 20, atomizer 30.Microcontroller 10 can be MCU, CPU, GPU or asic chip.Microcontroller 10 is connected with supplying cell 20, and atomizer 30 is connected with supplying cell 20.Atomizer 30 comprises oil storage cotton 31 and heating wire assembly 32.Wherein in oil storage cotton 31, store tobacco juice.The operation principle of electronic cigarette is that the tobacco juice in oil storage cotton 31 enters atomizer 30, and microcontroller 10 controls supplying cells 20 and be energized to atomizer 30, makes the heating wire assembly 32 in atomizer 30 generate heat to evaporate the tobacco juice mist formation.
The preservation of the tobacco juice in electronic cigarette need to, in lucifuge, at shady and cool dry place, be gone bad to prevent tobacco juice.And tobacco juice has the quality guarantee period, in the process of using electronic cigarette, need to, within the shelf-life, could keep the taste of tobacco juice.For the disposable electric cigarette, tobacco juice can not be changed, so, if tobacco juice surpasses the shelf-life, occur in the time of causing the user to use that mouthfeel is not good, and affect user's health.
As shown in Figure 2, be the structure chart of the electronic cigarette of the first preferred embodiment of the present utility model.In the first preferred embodiment of the present utility model, by the first timing module 11 is set in microcontroller 10, make electronic cigarette there is the shelf life prompting function.In the first preferred embodiment of the present utility model, electronic cigarette comprises microcontroller 10, supplying cell 20, atomizer 30, reminding module 40, smoking sensor 50, input module 60 and on-off circuit 70.Reminding module 40 is connected with microcontroller 10, for output display reminding information.Reminding module 40 comprises: light-emitting diode display and/or loudspeaker.Reminding module 40 also can comprise light emitting diode and/or loudspeaker.Smoking sensor 50 is connected with microcontroller 10, for detection of the smoking signal and by detection signal, sends microcontroller 10 to.Input module 60 is connected with microcontroller 10, for receiving external input signal and sending input signal to microcontroller 10.Input module 60 is keyboard input module or touch-screen input module.On-off circuit 70 is connected with microcontroller 10, supplying cell 20 and atomizer 30 respectively.Microcontroller 10 is by the shutoff of gauge tap circuit 70, to control supplying cell 20 and atomizer 30 conductings or disconnection.On-off circuit 70 is semiconductor switch.Semiconductor switch can be triode, metal-oxide-semiconductor, transistor, IGCT etc.
