Module 8 and heating wire component 9.To embody the core signal stream in the application emphatically, being electrically connected for power module 7 and partial function module is omitted in Fig. 2.
[0056] smoking trigger module 6 is sent to control module 8 for the signal that will smoke.In a preferred embodiment provided by the invention, smoking trigger module 6 can be the pass key Jian.User prepares smoking or to stop inch of smoking, it is only necessary to trigger the pass key Jian.The push button signalling of user can be sent to control module 8, and control module 8 further controls the on-off of electronic cigarette.In another preferred embodiment provided by the invention, smoking trigger module 6 can also be air flow sensor.User's smoking inch, air flow sensor can sense the negative pressure because generating in user's smoking inch electronic cigarette, and when negative pressure is more than preset threshold inch, air flow sensor sends smoking signal to control module 8 to start electronic cigarette.
[0057] after control module 8 receives the smoking signal that smoking trigger module 6 is sent, control optical transmitter module 2 shines.
After the incident ray 20 that optical transmitter module 2 issues is irradiated in oil storage cotton 11, a part of light is reflected by oil storage cotton 11, and a part of light transmits away from oil storage cotton 11.Reflection light 40 is received and converted into the first electric signal by the first optical receiver module 31 and is sent to control module 8, and transmitted ray 60 is received and converted into the second electric signal by the second optical receiver module 32 and is sent to control module 8.The power of first electric signal and the second electric signal is related with the received luminous intensity of reflection light 40 and transmitted ray 60 respectively.And reflection light 40 and the luminous intensity of transmitted ray 60 are related with the tobacco tar amount that oil storage cotton 11 is absorbed.Therefore, the first electric signal and the second electric signal are all related to the tobacco tar amount that oil storage cotton 11 is absorbed, and this relationship has been stored in advance in control module 8.After control module 8 receives the electric signal that the first optical receiver module 31 and the second optical receiver module 32 are sent, according to the corresponding relationship of the electric signal and tobacco tar amount that prestore, it can be obtained tobacco tar amount information absorbed in oil storage cotton 11, and tobacco tar amount information be sent to oil mass cue module 5 and is shown.Same inch, if tobacco tar amount is sufficient, control module 8 can control the conducting of heating wire component 9, and heating wire component 9 powers on module 7 in turn, and by electroluminescent fever come atomization smoke oil, so that user normally smokes.If cigarette low on fuel, control module 8 ifs, is not turned on heating wire component 9, to stop smoking.
[0058] oil mass cue module 5 may include display screen and/or indicator light.Wherein, display screen is for showing number relevant to oil mass and/or text.And indicator light can indicate the number of oil mass by bright-dark degree, can also indicate low on fuel by way of flashing.It should be understood that in the present invention, oil mass cue module 5 is an optional function module, can choose whether to be included in electronic cigarette provided by the invention according to actual needs.
[0059] a kind of tobacco tar amount absorbed using optical signal detecting oil storage cotton 11 and true according to tobacco tar amount is present embodiments provided
The fixed electronic cigarette whether started can effectively prevent burning cotton, and testing cost is low, grasp tobacco tar amount with inch for user and provide a kind of intuitive and accurate method, have better user experience.
[0060] Fig. 3 is 3rd embodiment electronic cigarette circuit diagram provided by the invention.As shown in figure 3, the electronic cigarette circuit diagram of the present embodiment can be divided into two parts, a part is the circuit diagram of battery component 100, and another part is the circuit diagram of atomizer 200.Battery component 100 and atomizer 200 are electrically connected to each other by respective interface forms electronic cigarette circuit diagram.
[0061] wherein, in battery component 100, battery BT and power conversion unit 71 (as shown in dotted outline in FIG.) constitute the power module of the application, for providing voltage for each circuit module.Wherein, power conversion unit 71 is used to the voltage of battery BT being converted into suitable voltage.Voltage input after the conversion of power conversion unit 71 is into optical transmitter module, the first light detection module 31 and the second light detection module 32.As shown in figure 3, power conversion unit 71 includes a voltage conversion chip U3.In the present embodiment, the model TLV70430 of the voltage conversion chip U3, voltage conversion chip U3 share 3 pins and are used, and the 1st pin is voltage input end Vi n, 3rd pin is voltage output end Vout, and the 2nd pin is ground terminal GND.The 1st bow I foot of voltage conversion chip U3 connects the anode of battery BT, and the 3rd bow I foot of voltage conversion chip U3 is respectively connected to the anode of Light-emitting diode LED 5, resistance R4 and resistance R5, the 2 pins ground connection of voltage conversion chip U3.In addition, being also connected with a capacitor C2 between the 1st and the 2nd pin of voltage conversion chip U3, the of voltage conversion chip U3 has been also connected with a resistance R3 and a capacitor C3 between 3 and second pin.The pass key Jian SW2 is smoking trigger module, and user closes SW2 by triggering key Jian and smoking signal is sent to microcontroller U4.Jian closes pipe Q2 and microcontroller U4 and constitutes control module.Light-emitting diode LED 3 and LED4 constitute oil mass cue module.
