Description
Technical field
The present invention relates to electronic cigarette technical field, particularly relate to a kind of atomizer assembly, limit electronic cigarette and the method in restriction electronic cigarette life-span in life-span。
Background technology
Electronic cigarette is a kind of relatively conventional simulation cigarette electronic product, is mainly used in smoking cessation and cigarette substitute；The structure of electronic cigarette mainly includes battery component and atomizer assembly；When the smoking action of smoker being detected, battery component is that atomizer assembly is powered, and makes atomizer assembly be in opening；After atomizer assembly is opened, heating wire generates heat, and tobacco juice is heated and evaporates atomization, forms the aerosol of simulated flue gas, thus allowing user have the sensation of a kind of similar smoking when inhaling。
In early days, many atomizer assemblies do not have the life-span (such as smoking port number) to limit, as long as connecting battery component to power to atomizer assembly, atomizer assembly just can turn on work, and during section, tobacco juice is sufficient before use, thus flue gas pure in mouth feel, but to when using back segment, causing that amount of smoke reduces owing to tobacco juice tails off, even occurring burning the situation of cotton abnormal flavour, thus bringing very bad experience to user。
At present, for the problems referred to above, pertinent literature is had to propose the structure of electronic cigarette is improved, control unit is added in battery component, for smoking port number is added up, and atomizer assembly is disconnected when smoking port number reaches preset value, the phenomenon that amount of smoke reduces and burns is caused to avoid tobacco juice to tail off；But, in existing scheme, as long as electronic cigarette receives smoking signal (as button triggers the smoking signal formed), control unit begins to statistics smoking port number, reduces remaining available mouth number simultaneously；But, in actual use, atomizer assembly would be likely to occur situation about disconnecting with battery component, occur loosening individually placed with battery component disconnection or battery component such as atomizer assembly and be not connected with atomizer assembly, now control unit and battery are still in connected state, when user misoperation (encounter smoking trigger key such as imprudence or child plays and sends smoking action etc. to electronic cigarette) triggers generation smoking signal, control unit still can carry out smoking port number statistics, and reduce the available smoking number of times of electronic cigarette, and actually atomizer assembly does not start, tobacco juice is not consumed yet；So just cause available smoking port number to reduce in vain, namely occur when in control unit, the smoking port number of statistics reaches preset value, and when electronic cigarette is unavailable, electronic cigarette also remains available tobacco juice。

Embodiment one
Refer to Figure 1A and Figure 1B, embodiments provide a kind of atomizer assembly 10, for forming electronic cigarette with battery component 20 combination, atomizer assembly 10 includes:
For the interface circuit 101 removably connected with battery component 20, the atomization circuit 102 being connected with interface circuit 101 and main circuit 103；
Main circuit 103 is for by after interface circuit 101 and battery component 20 electric connection, the number of times that is actually turned on according to atomization circuit 102 adds up smoking port number, so that described electronic cigarette controls atomization circuit 102 and disconnects and terminate work when described smoking port number reaches preset value。
In the embodiment of the present application, the atomizer assembly 10 of electronic cigarette and battery component 20 can pass through interface circuit 101 and removably connect；Concrete, refer to Fig. 2 A and Fig. 2 B, interface circuit 101 includes: connector 1011 and a plurality of connecting line 1012 being connected with atomization circuit 102 and main circuit 103 drawn from connector 1011。As shown in Figure 2 A, connector 1011 is row's seat, described row's seat is provided with row bore 1011-1 side by side, corresponding, battery component 20 arranges the pricking with needle matched with described row's seat, by described pricking with needle being inserted or pull out described row bore 1011-1, to realize removably connecting of battery component 20 and atomizer assembly 10；Wherein, the number arranging bore 1011-1 is determined according to concrete condition；Such as, battery component 20 is powered for atomizer assembly 10 mainly through interface circuit 101, then row bore 1011-1 includes two holes of power supply and ground。Again as shown in Figure 2 B, connector 1011 is deck, described deck is provided with contact point 1011-2 side by side, corresponding, battery component 20 is provided with and the deck contact point 1011-2 contact point mated, by battery component 20 is snapped in or extract described deck, to realize removably connecting of battery component 20 and atomizer assembly 10, same, the number of contact point 1011-2 is determined according to concrete condition, is not specifically limited here。
In specific implementation process, battery component 20 includes the smoking motion detector for detecting user's smoking action, and described smoking motion detector can be airflow sensor device or soft-touch control etc., is not especially limited at this；After smoking motion detector detects user's smoking action, and when battery component 20 passes through interface circuit 101 with atomizer assembly 10 physical connection, battery component 20 is powered for main circuit 103 by interface circuit 101。Main circuit 103 adds up smoking port number according to the number of times that is actually turned on of atomization circuit 102, and " being actually turned on " mentioned here refers to that atomization circuit 102 gets the electric energy being effectively atomized ree-oil from battery component 20；Concrete, atomization circuit 102 includes heater members (such as resistance wire), and when atomization circuit 102 is actually turned on and when atomization circuit 102 fault-free, heater members can generate heat, tobacco juice is heated evaporation atomization。Further, electronic cigarette is according to described smoking port numerical control atomization circuit 102, and control atomization circuit 102 disconnects and terminates work when described smoking port number reaches preset value；Another it is noted that above-mentioned preset value can be set according to the statistical value of tobacco juice volume in tobacco juice composition, electronic cigarette and the tobacco juice waste of smoking every time, it is specifically as follows 290 mouthfuls or 300 mouthfuls etc., is not especially limited here。
In specific implementation process, main circuit 103 adds up described smoking port number for the number of times that is actually turned on according to atomization circuit 102, and when with battery component 20 electric connection, described smoking port number is provided, so that battery component 20 controls atomization circuit 102 and disconnects and terminate work when described smoking port number reaches described preset value to battery component 20；Main circuit 103 or add up described smoking port number for the number of times that is actually turned on according to atomization circuit 102 and directly control atomization circuit 102 when described smoking port number reaches described preset value and disconnect and terminate work。It is to say, the controller for controlling atomization circuit 102 on-off of electronic cigarette may be provided in atomizer assembly 10, it is possible to be arranged in battery component 20, below both of these case be introduced respectively:
1) situation one: atomization circuit 102 on-off controller is arranged on battery component 20 inside, and smoking port number memorizer is arranged on atomizer assembly 10 inside。
Main circuit 103 is: memory integrated circuit, and it provides described smoking port number by interface circuit 101 to battery component 20, so that described battery component controls atomization circuit 102 and disconnects and terminate work when described smoking port number reaches described preset value。Described controller controls the on-off of atomization circuit 102 again by interface circuit 101。
Refer to Fig. 3 A, atomizer assembly 10 is internal adopts memory integrated circuit (IC, integratedcircuit) to store the information such as smoking port number。As the IC of storage data, in this embodiment, using model is the memory chip of DS2431；It addition, the difference according to actually used situation, memory integrated circuit can also adopt the memory IC of other models, such as ST24C02 etc.。In figure 3 a, memory integrated circuit DS2431 includes 6 pins (1-I/O, 2-GND, 3-NC, 4-NC, 5-NC, 6-NC), the connector JP1 of interface circuit 101 is provided with four terminals (1～4), wherein, terminals 2 and the terminals 1 of connector JP1 are connected with pin 1-I/O and pin 2-GND respectively, and terminals 3 and terminals 4 are connected with the two ends of the heating resistance wire R1 in atomization circuit 102 respectively。
Its specific works principle is: after battery component 20 detects user's smoking action, and battery component 20 by interface circuit 101 with atomizer assembly 10 physical connection time, controller in battery component 20 is communicated by the data input and output pin 1-I/O of the terminals 2 of connector JP1 with DS2431, read the residue smoking port number of DS2431 storage inside, and described smoking port number and preset value are compared, if the current residue smoking port number read is more than preset value (such as 1), explanation may continue to smoking, the battery component 20 terminals (3 by connector JP1, 4) power for resistance wire R1 and make it generate heat, if the current residue smoking port number read is less than or equal to preset value, explanation can not continue smoking, battery component 20 stops powering for resistance wire R1, and then make atomization circuit 102 and power supply disconnect termination work。In specific implementation process, user often has a suck of cigarette, and stored for the memory integrated circuit within atomizer assembly 10 smoking port number is subtracted one by the controller in battery component 20, then updates the residue smoking port number in memory integrated circuit；Such as, being previously stored with smoking port number in memory integrated circuit is 300, when user smokes, controller in battery component 20 is the smoking port number of reading value 300 from the memory IC of atomizer assembly 10, after smoking one time, controller subtracts one by 300, becomes 299 mouthfuls, then, then by this number of 299 mouthfuls write back in the memory IC in atomizer assembly 10；Preset value now may be configured as 1, and when the smoking port number that controller reads is be more than or equal to 1, battery component 10 is powered for resistance wire R1, when the smoking port number of reading is less than 1, and battery component 10 off resistance silk R1 supply line。
Certainly, after battery component 20 reads current smoking port number from memory IC, also by judging that whether this smoking port number is less than or equal to preset value (such as 299), if the current smoking port number read is less than or equal to preset value, explanation may continue to smoking, battery component 20 is powered for resistance wire R1 by the terminals (3,4) of connector JP1 and is made it generate heat, if the current smoking port number read is more than preset value, explanation can not continue smoking, battery component 20 is not powered for resistance wire R1, and then makes atomization circuit 102 and power supply disconnect termination work。In specific implementation process, user often smokes one time, and stored for the memory IC within atomizer assembly 10 smoking port number is added 1 by the controller in battery component 20, then updates the smoking port number in memory IC；Such as, being previously stored with smoking port number in memory IC is 0, when user smokes, the smoking port number of the controller reading value 0 in battery component 20, after smoking one time, controller adds one by 0, become 1 mouthful, then, then this number of 1 mouthful is write back in the memory IC within atomizer assembly 10；Preset value now may be configured as 299, and when the smoking port number that controller reads is less than or equal to 299, battery component 20 is powered for resistance wire R1, and when the smoking port number read is more than 299, battery component 10 is not powered for resistance wire R1。
It addition, described memory integrated circuit also can adopt with the single-chip microcomputer of nonvolatile memory, FPGA etc.。Concrete, illustrate for described memory integrated circuit for single-chip microcomputer PIC12F519:
As shown in Figure 3 B, single-chip microcomputer PIC12F519 includes 8 pins (1-VDD, 2-RB5,3-RB4,4-RB3,5-RB2,6-RB1,7-RB0, GND)；The connector J1 of interface circuit 101 is provided with three terminals (1～3)；Wherein, the terminals 3 of connector J1 meet the power pin 1-VDD of single-chip microcomputer PIC12F519 by diode D1；Terminals 2 are connected with the pin 2-RB5 of single-chip microcomputer PIC12F519；Terminals 1 ground connection；Terminals (1,3) are also connected with the two ends of the heating resistance wire R1 in atomization circuit 102 respectively；The one terminating diode D1 of electric capacity C1, other end ground connection。
Its operation principle is: the effect of the pin 2-RB5 of single-chip microcomputer is to carry out communication with battery component 20, determines whether battery component 20 can control conducting atomization circuit 102。Single-chip microcomputer PIC12F519 can be smoking port number or communication command to the Content of communciation that battery component 20 feeds back, and wherein, described communication command is specially order 1 (can turn on) and order 2 (cannot turn on)。In specific implementation process, after battery component 20 detects user's smoking action, and battery component 20 by interface circuit 101 with atomizer assembly 10 physical connection time, battery component 20 is powered to the single-chip microcomputer PIC12F519 in atomizer assembly 10 by the terminals 3 (as shown in Figure 3 B) of connector J1；Concrete, electric capacity C1 is charged by diode D1, after charging, single-chip microcomputer PIC12F519 begins to run, single-chip microcomputer obtains the reading instruction of battery component 20 by pin 2-RB5, when described reading instruction is for requiring singlechip feedbsck smoking port number, then smoking port number is fed back to battery component 20 yet by pin 2-RB5 by single-chip microcomputer, (specifically how to compare so that battery component 20 compares with preset value based on the current smoking port number read, with scheme shown in above-mentioned Fig. 3 A, here no longer repeat one by one), judge whether atomizer assembly 10 can continue to work (namely whether user can continue to smoking), when judged result is no, then stop powering for atomizer assembly 10, when judged result is for being, then continue as atomizer assembly 10 and power (being specially resistance wire R1 to power)；When described reading instruction is for requiring communication command described in singlechip feedbsck, single-chip microcomputer then reads the smoking port number of storage inside, and compare with preset value based on the current smoking port number read, judge whether atomizer assembly 10 can continue to work, when judged result is for being, would indicate that the described order 1 of " can turn on atomization circuit 102 " feeds back to battery component 20, so that battery component 20 can continue to power for atomizer assembly 10, when judged result is no, would indicate that the described order 2 of " cannot turn on atomization circuit 102 " feeds back to battery component 20, so that battery component 20 is stopped power supply。It addition, for after this smoking, the processing mode added deduct of the smoking port number being stored in single-chip microcomputer PIC12F519 is also with scheme shown in above-mentioned Fig. 3 A。
It need to be noted that be, in figure 3b, battery component 20 by connector J1 be single-chip microcomputer PIC12F519 power time, also powering for heating resistance wire R1 simultaneously, but this does not conflict with the present invention program, because battery component 20 is powered for single-chip microcomputer PIC12F519, and obtain for controlling the control instruction whether atomization circuit 102 turns on, consuming time very short, it is unlikely to make the temperature of resistance wire R1 rise to the temperature levels that can make tobacco juice that atomization occurs, or, even if there is a small amount of atomization in tobacco juice, also it is the shorter time, thus can not effectively be atomized ree-oil；Therefore, even if the conclusion that battery component 20 finally obtains is for being not turned on atomization circuit 102 (namely cannot supply user's smoking), without adverse consequencess such as burning occurs。
2) situation two: it is internal that atomization circuit 102 on-off controller and smoking port number memorizer are arranged at atomizer assembly 10。
