The specific embodiment
Below will to the utility model, be described further by embodiment, the description of these embodiment is not that content of the present utility model is done to restriction.One skilled in the art will understand that the replacement that is equal to that the utility model content is done, or corresponding the improvement, within still belonging to protection domain of the present utility model.
As shown in Figure 1, a kind of electronic cigarette control chip with lock function of the present utility model, checkout gear is connected with internal control device, and internal control device is connected with drive unit with the LED display unit.Wherein, checkout gear mainly the equivalent capacity by detecting external capacitive formula miaow head and capacitance variations determine system in which kind of in (standby stage in stage, smoking state or air blowing state), and will indicate that the state flag bit of state outputs to internal control device; Internal control device mainly decides the working method of drive unit and LED display unit according to the state flag bit of checkout gear, drive unit is that the drive control signal of sending according to internal control device is carried out corresponding operating generation heating current to power switch pipe, and the LED display unit is controlled outside LED lamp according to the demonstration output of internal control device each state is carried out to necessary demonstration.The utility model is by detecting the operational motion of user to cigarette holder, mainly to detect air-flow to judge that whether the user is in smoking state, and by internal control device, this state is responded, the heating wire of accessory drive heating simultaneously produces the equipment of smoking action.Pneumatic sensor generally adopts condenser type miaow head, and condenser type miaow head is comprised of conductive film and substrate, and when the changing of the air-flow that flows through the miaow head, conductive film produces corresponding deformation, and change has occurred the equivalent capacity between conductive film and substrate.
As shown in Fig. 3 A, Fig. 3 B and Fig. 3 C, when air-breathing, conductive film under the effect of air pressure towards base plate deformation, if the acquiescence spacing between conductive film and substrate is D0, the first-class effect capacitor C of miaow eff=C0 now.When smoking, equivalent separation between conductive film and substrate becomes D0-Δ d1, simultaneously, miaow head electric capacity also has default value C0 to increase to Ceff=C0+C1, equally, during air blowing, the equivalent separation between conductive film and substrate becomes D0+ Δ d2, electric capacity also, by the capacitance C0 of acquiescence, is reduced to Ceff=C0-C2 simultaneously.Due to condenser type miaow head switching regulator miaow head different from the past, when the user is air-breathing and air blowing all can exert an influence to equivalent capacitance value, as the C1 in figure and C2, if the user blows or air-breathing dynamics is suitable, C1 and C2 can reach the threshold value of inner setting equally, cause like this user also can cause the false triggering of control circuit in wrong air blowing operating process.
As shown in Figure 2, checkout gear mainly comprises sampling apparatus, memory, and comparison operation circuit A and B, after system powers on, at first the sample equivalent capacitance value of external capacitive formula miaow head of sampling apparatus in checkout gear, and it is stored in internal storage, and passing threshold arithmetic unit, the threshold value of capacitance change is determined in computing, and by this threshold value storage, sampling apparatus is the first-class effect electric capacity of sampling miaow periodically, and after finishing, by comparison operation circuit A, sampled value and storing value are compared in each sampling period, when being greater than storing value, sampled value thinks in suction condition, and both differences and internal threshold are compared by comparison operation circuit B, if difference is greater than internal threshold, decision-making system is in smoking state, equally, when comparison operation circuit A judges that the sampling capacitance value is less than storing value, think in the air blowing state, simultaneously, if comparison operation circuit B judges, when the difference of sampled value and storage inside value is greater than internal threshold, think that the user is carrying out wrong air blowing operation, now will send air blowing maloperation signal to internal control device.During the output smoking signal of the checkout gear received when internal control device, send and drive signal to drive unit respectively, make drive unit promote power tube and produce heating current, the atomization tobacco tar, reach smoking effect; Send normal smoking to the LED display unit simultaneously and show, the LED display unit is controlled the indication that the external LED lamp carries out normal smoking.When the user who receives checkout gear output when internal control device blows the maloperation signal, internal control device is sent lock control signal to drive unit, the lock drive device keeps closed condition, afterwards, if there is no the output of unlocking signal, the equal conductively-closed of any signal that drive unit sends to drive unit; Also to the LED display unit, send the locking display with timed unit, the LED control device is controlled the LED lamp and is shown the locking indication, and indicating user now electronic cigarette enters locking mode.In order to save design cost and to be user-friendly to, after unlocking manner is designed to system lock, if checkout gear detects user misoperation air blowing action again, internal control device is sent unlocking signal to drive unit, also to the LED display unit, send the release display simultaneously, indicating user now system lock state is removed, can carry out normal operating.Function based on above, if user error electronic cigarette is operated, LED can indicate lock-out state, the simultaneity factor locking, guaranteed that drive unit is not by false triggering.
A kind of electronic cigarette control chip with lock function of the present utility model, effectively prevent that user's misoperation of in use blowing from causing the erroneous trigger of electronic cigarette drive unit.The principle of moving due to condenser type miaow head response external still causes what the deformation initiation capacitance variations of conductive film realized by air-flow, if in smoking process, conductive film is towards the direction deformation of substrate, be also that capacitance increases, so in user's air blowing process, conductive film is towards the direction deformation away from substrate, be also that capacitance reduces, internal control device judges user's action by the change direction that at first judges electric capacity like this, and then the variable quantity of Detection capacitance, when reaching certain value, variable quantity makes corresponding judgement, when final judgement during in smoking state, normally to drive unit, send control signal, the heating heating wire, during maloperation as final judgement user in blowing, lock internal control device, under locking mode, any smoking action control part of user does not all respond, after user's release action only being detected, the internal control device release, circuit returns to normal mode of operation.In whole process, the electronic cigarette chip can be controlled the external LED lamp and make corresponding demonstration, facilitates the user in real time the residing state of electronic cigarette to be judged simultaneously.The utility model detects user's smoking action by pneumatic sensor, and according to the output of pneumatic sensor by the computing of internal processor, control conducting and the disconnection of output switch power tube, realize the effect of smoking.Because pneumatic sensor mainly carrys out the perception outer gas stream by capacitance variations, when electronic cigarette is had to improper operation, especially the user is blown rather than aspiratory action to electronic cigarette, the capacitance change of pneumatic sensor also can reach certain threshold value, internal processor can be judged disconnected user by accident in smoking state, cause the false triggering of electronic cigarette drive unit, cause the unnecessary loss of battery electric quantity.The utility model is realized the two-way detection of electronic cigarette air-flow by the acting in conjunction of checkout gear and internal control device, carrying out aspiratory action when the user being detected, and, when the variable quantity of air-breathing effect electric capacity surpasses the threshold value presetted, just can be operated drive unit; Blowing when action and the user detected, after capacitance change that air blowing causes surpasses the air blowing threshold value certain hour presetted, by the electronic cigarette locking, until detect again after the action of blowing its release.In locking process, the user carries out any operation to electronic cigarette, and the electronic cigarette internal processor all keeps the closed condition of drive unit, has avoided because wrong air blowing action causes that the miaow capitiform becomes the logic false triggering situation caused.
