The chip provided by the utility model achieves circular charging for an electronic cigarette, and prolongs the service life of the whole electronic cigarette.
Description
Technical field
The utility model relates to a kind of electronic cigarette control chip with charge function.
Background technology
Electronic cigarette is a kind of by powered battery, and the motion that is detected air-flow by internal inspection device judges whether in smoking state, and heater strip is operated, thereby realizes the electronic equipment of smoking effect.In order to be user-friendly to, electronic cigarette appearance design and common cigarette comparing class seemingly, and are assembled in smoke pipe inside by battery, control chip and tobacco tar heater strip etc.But because the smoke pipe space of electronic cigarette is also little, simultaneously owing to considering the factor of cost, the battery that electric weight is larger cannot be installed in inside, so common electronic cigarette, once internal cell electric weight exhausts, also just indicate the end in electronic cigarette life-span, in the service life of how to improve electronic cigarette, become the major concern point that present electronic cigarette designs.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present utility model is to provide a kind of electronic cigarette control chip with charge function of practicality, has realized the cycle charging to electronic cigarette battery, has extended the service life of whole electronic cigarette.
For reaching above-described object, a kind of electronic cigarette control chip with charge function of the present utility model is taked following technical scheme:
A kind of electronic cigarette control chip with charge function, it is characterized in that, miaow head is connected with smoking detector, and described smoking detector is connected with control device, described control device is connected with drive unit, display unit and charging device, and described charging device is connected with drive unit.
The input port of described charging device is also the output of heater strip electric current simultaneously.
Can internal cell be charged by the input of described charging device.
Described display unit is LED display, pilot cell service condition.
Adopt as above the utility model of technical scheme, there is following beneficial effect:
Realize the cycle charging to electronic cigarette battery, extended the service life of whole electronic cigarette.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is charging current of the present utility model and supply voltage curve map.
The specific embodiment
To the utility model, be described further by embodiment below, the description of these embodiment is not that content of the present utility model is limited.One skilled in the art will understand that the replacement that is equal to that the utility model content is done, or improve accordingly, within still belonging to protection domain of the present utility model.
As shown in Figure 1, a kind of electronic cigarette control chip with charge function of the present utility model, miaow head is connected with smoking detector, and smoking detector is connected with control device, control device is connected with drive unit, display unit and charging device, and charging device is connected with drive unit.In normal smoking situation, smoking detector is according to the capacitance variations of outside miaow head, judge whether in smoking state, and state flag bit is sent into control device, control device is controlled drive unit and display unit accordingly according to the state flag bit of smoking detector, when smoking detector is sent smoking flag bit, simultaneously when cell voltage is normal, control device is controlled display unit and is shown smoking state, accessory drive is to heating wire output current simultaneously, when cell voltage is not enough, control device sends electric weight shortage signal and cuts out drive unit to display unit, display unit is externally made the alarm indication of electric weight deficiency simultaneously.When smoking detector is sent standby flag bit, control device cuts out drive unit, and controls after display unit demonstration smoking stops and closing.During charging, when charging device detects output port connecting charger, to control device, send charging enable signal, control device receives after charging enable signal, to display unit, sends charging display, shows charged state, and detect in real time cell voltage, after battery is full of, to display unit, send and be full of display, show that battery charging finishes.In whole charging process, when the enable signal that namely charges is effective, drive unit cuts out all the time, has avoided like this charging port and power port to produce interference by drive unit simultaneously.In order to realize safety and efficient charging process, the utility model has carried out well-designed to charging device, and charging current is as shown in Figure 2 along with the characteristic curve of cell voltage.When cell voltage is lower (< Vth1), in order battery not to be caused to unnecessary damage, improve the life-span of rechargeable battery, charging device adopts less electric current (Ismall) to carry out trickle charge to internal cell; Until cell voltage is while reaching certain value (> Vth1), charging device switches to charging current the charged state (Ilarge) of large electric current constant current automatically, guarantees the high efficiency of charging; When cell voltage approaches while being full of point (> Vth2), charging module is switched to pressure constant state, and in this state, charging current progressively reduces, until control circuit detects cell voltage, reaches and is full of point (Vfull).
A kind of electronic cigarette control chip with charge function of the present utility model, has realized the cycle charging to electronic cigarette battery, has extended the service life of whole electronic cigarette.In order to facilitate the electric weight situation of user's detected electrons cigarette internal cell, the electronic cigarette control chip of the clear demonstration battery electric quantity of the utility model design energy, owing to considering the miniaturization of electronic cigarette control chip, in order not increase pin number, the utility model adopts pin multiplexing technology, be about to output port (OUT) as the output of the heater strip electric current in electronic cigarette course of normal operation, can be used as again the charging input end mouth in charging process simultaneously.And, the utlity model has LED deixis easily, when the not enough generation of battery electric quantity LED display alarm, can to internal cell, charge by output port, realize the reusable of internal cell, increase the life-span of electronic cigarette, in whole charging process, be also accompanied by LED indication clearly simultaneously, in real time the charge condition (charge or be full of) of pilot cell.When charging port access charging equipment being detected, control device produces charging enable signal, and the drive unit of electronic cigarette is not worked, whole system enters charge mode, monitor cell voltage simultaneously, the state of battery in judgement charging process, and by display unit, charged state is indicated.In order to guarantee the reliability of charging process, charging device adopts little electric current trickle charge and the switching mode of large electric current constant-current charge to charge to battery, when cell voltage is lower, in order to guarantee the security of battery, charging device enters trickle charge pattern automatically, by less electric current, battery is charged, prevent the shock effect battery life of large electric current to battery, when cell voltage rises to certain value, charging device automatically switches to large electric current constant-current charge state, when cell voltage approaches while being full of, charging device switches to constant-voltage charge state, such charged state is switched, avoided cell voltage to cross the damage of large current charge to battery while putting, the simultaneously guaranteed efficiency of battery charging.
