Fig. 2 is electronic cigarette controller structural representation of the present utility model.
Fig. 3 is electronic cigarette built-in function block diagram of the present utility model.
Detailed description of the invention
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, the electronic cigarette of a kind of novel band tobacco tar measuring ability of the present utility model, comprise that miaow head, control chip, battery, oil storage are cotton, the heater strip of atomizing functions and LED, heater strip provides heat for being atomized, battery provides power supply for whole electronic cigarette, and LED is as the indicator of electronic cigarette current state.The VDD pin of control chip connects anode, VSS pin ground connection, AT pin connects the heater strip of atomizing functions, simultaneously also as the charging inlet of battery, LED pin connects LED, SW pin connects miaow head, and NCT pin connects oil storage cotton, as the sampling end of tobacco tar, when tobacco tar quantity not sufficient with provide heat and the demand be atomized time, electronic cigarette controller can be pointed out by LED, and makes electronic cigarette controller export cut-off, thus makes the security of the use adding electronic cigarette.
As shown in Figure 3, control chip adopts SOT23-6 encapsulation, each module is included, as preferably, control chip comprises smoking detection module, LED driver module, charging module, driver module, control module and tobacco tar detection module, smoking detection module is connected with control module with tobacco tar detection module, and control module is connected with driver module, LED driver module and charging module, and charging module is connected with driver module.Smoking detection module according to the difference of miaow head, can set 3%, 6%, 9%, 12% 4 different threshold value, the variable quantity of miaow head electric capacity when detecting smoking.Charging module adopts the multiplex mode of output port and charging input end mouth, when AT is greater than vdd voltage, as charging port, when AT is less than VDD, as output port, and has constant-current constant-voltage charging characteristic safely and efficiently.Protection module comprises short-circuit protection unit, under-voltage protection unit and over-current protecting unit, and short-circuit protection unit and over-current protecting unit are detected by AT end, and under-voltage protection unit is detected by vdd terminal.Tobacco tar detection module can accurately detect tobacco tar amount by the NCT pin of control chip, and clearly indicates tobacco tar amount by LED.
Under normal tobacco smoking status, smoking detection module, according to the capacitance variations of outside miaow head, judges whether to be in smoking state, and state flag bit State is sent into control module.Control module controls driver module and display module accordingly according to the state flag bit of detection module, when detection module sends smoking flag bit, simultaneously when cell voltage is normal, control module controls display module display smoking state, control driver module to heating wire output current simultaneously, when cell voltage is not enough, control module sends electricity shortage signal to display module and closes driver module, and display module externally makes the alarm indication of electricity deficiency simultaneously.When detection module sends standby flag bit, control module is closed driver module and is controlled to close after display module display smoking stops.
When tobacco tar amount is low, electronic cigarette controller flows through the electric current of oil storage cotton by pin sampling, this electric current is compared by current comparator with internal reference electric current, when sample rate current is less than internal reference electric current, comparator exports as low, and send the low enable signal of tobacco tar amount (NCT_en) to control module, after control module receives enable signal, the low display of tobacco tar amount is sent to display module, LED connects sudden strain of a muscle three times, and send shutdown signal to driver module, power output pipe is quit work.
The present embodiment in a power-save mode quiescent current is less than 3uA, and during smoking, the electric current of atomizing piece is greater than 1A; This chip has visual LED work deixis simultaneously, according to different application states, has diacritic LED to indicate in chip enable, smoking period, voltage detecting, short-circuit protection, open-circuit-protection and charging process; Charging performance is superior, has perfect battery protection function; Include charging control circuit, support the charging equipments such as common fiery ox and USB.Be trickle charge when lithium cell charging voltage is less than 2.7V, can guarantee not damage battery, guarantee safety; When being charged to more than 2.7V, start large current charge, when voltage is close to 4.2V, charging current progressively declines.Charging voltage metrical error can be accomplished within 1%.Peripheral applications circuit is simple.Integrated voltage-stabilized pipe in IC, easy to process, reduce the wastage; Adopt SOT23-6 encapsulation, volume is little; Peripheral cell is few, and only use a LED lamp and an electric capacity, system cost is low.
