Detailed Description
In order that the invention may be readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
The control method of the electronic cigarette according to an embodiment of the present invention is preferably applied to a split electronic cigarette product with a structure shown in fig. 1, and includes an atomizer 10 and a power supply device 20 that are detachable from each other; the atomizer 10 and the power supply means 20 are connected mechanically while forming an electrically conductive connection. Also, the functional blocks of the structure of the power supply device 20 may be as shown in fig. 2, including:
A cell 21;
an airflow sensor 22 for sensing the flow of smoke from the atomizer 10;
And the controller 23 is used for controlling the operation of the battery cell 21, the airflow sensor 22 and the functional modules of the electronic cigarette product.
The low-power consumption control method of the electronic cigarette is based on the fact that when the controller 23 is usually designed in the original mode of a chip, the controller is set with use modes with different power consumption, such as a high-power consumption working mode, a low-power consumption standby mode, an extremely low-power consumption shutdown mode and the like; of course, the power consumption of each use state described above is relative. The controller 23 itself can have different power consumption modes generated based on the functional configuration of the chip at design time, and typically the chip includes a power manager, a main state machine, a chip transceiver, a central processor, and a memory, where the operation performance of each module requires determining the operation clocks of the slave chip transceiver, the central processor, and the memory, such as 32MHz, 64MHz, or 96 MHz. Based on the design requirements for realizing different power consumption modes, each functional module is positioned in different clock domains; such as is commonly employed in chip designs, to operate the power manager in a relatively low clock domain, such as 32KHz; the states of the functional modules can be controlled through the difference of working clocks, so that the chip is in different power consumption modes.
In the present electronic cigarette product, the operation mode is a high power consumption use state when all necessary functional modules related to the controller 23 are turned on in order to perform smoking operation. The standby mode is to selectively turn off all the necessary functional modules of the controller 23 when smoking is not needed or smoking is not needed, and to enable the controller 23 to be in a low power consumption use state in which the controller can be awakened by timing counting during monitoring operation, and in the standby mode, the modules relevant to part of counting functions are in an on state, such as watchdog, time base timer and the like; the standby mode can wake up by a self-contained timing counting wake-up software program during chip design, so that the chip enters into the working mode. The shutdown mode is a very low power consumption use state when all the functional modules of the controller 23 are turned off, and in the shutdown mode, the controller can only wake up through interrupt processing (such as high-low level change, restarting and the like) of an interrupt source, and the controller enters an initial stage of a program, such as shown in fig. 3, after waking up based on the use requirement of the electronic cigarette product.
Based on the above control method of the electronic cigarette of the present invention, the controller 23 and each hardware are accurately controlled according to the transformation of the function module and the detection of the action, so that the power consumption can be reduced while the product usage is satisfied, and the flowchart of a specific method in a preferred embodiment can be seen as shown in fig. 3, and the method comprises the following steps:
S10, resetting each software and hardware of the electronic cigarette to enable the software and hardware to be restored to an initial state suitable for execution of a power consumption control process of the method, and starting to enter a power consumption control program;
S20, controlling the battery cell 21 to output power to the controller 23, and adjusting the controller 23 to enter a working mode;
S30, controlling the airflow sensor 22 to detect whether smoking airflow exists currently and receiving a sensing signal fed back by the airflow sensor 22; if the current smoking airflow is detected, the user is indicated to smoke, and the controller 23 is not subjected to mode change adjustment, so that the controller is continuously in a working mode to perform smoking operation, and detection is continuously performed; if no smoking airflow is detected, the process proceeds to step S40;
S40, detecting whether the atomizer 10 is connected to the current power supply device 20; if yes, the control unit controls the battery core 21 to output power to the controller 23, adjusts the controller 23 from the working mode to the standby mode, and proceeds to step S50; if not, the controller 23 is adjusted from the working mode to the shutdown mode;
s50, entering a timing wake-up program, and carrying out timing wake-up on the controller 23 in the standby mode according to a certain frequency by the controller 23, wherein the timing wake-up comprises:
s51, detecting whether the atomizer 10 is connected to the current power supply device 20; if yes, go to step S52; if not, the controller 23 is adjusted from the standby mode to the shutdown mode;
S52, controlling the airflow sensor 22 to detect whether the current atomizer 10 has smoking airflow; if yes, returning to the step S20, adjusting the controller 23 to a working mode, and starting each function module related to smoking to smoke; if not, the next wake-up is entered.
The steps of the complete power consumption control flow of the electronic cigarette in the above embodiment are executed at the moment when the user turns on the power supply to start the power-on action or the external interrupt source to perform interrupt processing; in the implementation, the power consumption mode of the controller is adjusted and controlled according to the conversion of the program and the detection of the action, so that the purpose of reducing the power consumption is realized.
The reset in step S10 is to make the method consistent with the user' S power-on action and interrupt processing action, enter the control program in the state of user power-on use/reset after interrupt, and execute the power consumption control step. Of course, the most important thing to reset is to restore the hardware and software associated with the smoking control, such as the controller 23, to the original state.
The following steps S20 and S30 set the working mode as the start state in the control program, and then adjust the mode correspondence to the standby mode and the shutdown mode with low power consumption according to whether the user smokes and whether the atomizer 10 is connected on line. And according to the operation action of the user, carrying out timing awakening on the standby mode and carrying out interrupt awakening on the shutdown mode through an external interrupt source or a set interrupt signal. Among them, the preferred embodiment is to detect the change of the air flow generated by the smoking action of the user by the air flow sensor 22 to determine whether smoking is performed; in other variant implementations, the smoking action of the user can be monitored by detecting the negative pressure generated by the user's smoking through an air pressure sensor to determine whether to smoke or not, or by responding to the triggering of a mechanical micro switch of the air flow, and the like.
While steps S30 and S4 respectively adjust the controller 23 to a standby or shut down mode by detecting whether smoking and the atomizer 10 are connected, respectively. Or in the variation control, it is possible to employ in step S30 that the controller 23 is first adjusted to enter the standby mode when no smoking airflow is detected; the following step S40 is to perform state adjustment on the controller 23 in standby mode according to whether the atomizer 10 is connected, and select to keep standby or further adjust to shutdown.
The above manner of detecting whether the power supply device 20 is connected to the atomizer 10 in step S40 and step S51 may be performed in various manners, such as detecting the elastic pressure, the deformation amount, etc. generated by the deformation of the spring conductive needle when the power supply device 20 is connected to the atomizer 10 by the pressure sensor. In view of the reduction of power consumption, in the implementation of the present invention, it is preferable to measure and calculate the change information of the load resistance between the positive electrode and the negative electrode, which are the output electrode of the power supply device 20, to determine whether to connect or not after the power supply device 20 is connected to the atomizer 10, and the content of the method for detecting the specific resistance includes:
according to the mode shown in fig. 4, a voltage dividing resistor R1 connected in series with the two connected ends of the atomizer 10 is constructed, the voltage values of the two ends of the voltage dividing resistor R1 are collected by utilizing the self-contained voltage collection function of the controller 23, the value of the resistance value ret of the two connected ends of the atomizer 10 is calculated, and the calculated relational expression is (Vbat-Vadc)/r1=vadc/ret; wherein Vbat is the output voltage of the battery cell 21, vadc is the sampling voltage of the chip, and whether the atomizer 10 exists on the power supply device 20 can be detected by accessing the obtained atomizer 10 into the resistance value at two ends.
Further, the step S50 of periodically waking up step is to execute step S51 and step S52 in a cyclic manner according to a certain frequency, and trigger waking up the controller 23 when it is determined that there is a pumping action of the user during the cyclic process; wherein,
Before each cycle of step S50 begins, re-detecting whether the power supply device 20 is connected with the atomizer 10, which on one hand isolates the connection state of the atomizer 10 in the cycle from the connection state of the atomizer 10 in other steps or processes, so as to ensure that the triggering of the controller 23 is controlled only by the connection state of the atomizer 10 in the cycle; on the other hand, the step S50 and the steps S10 to S40 are executed in different software modules, and the steps S10 to S40 are executed in the main control program of the controller 23, and the step S50 is executed in a clock function module such as a watchdog or a time base timer provided in the controller 23.
The cycle is exited only during the entire cycle of the wakeup operation of step S50 in the embodiment when the atomizer 10 is unplugged from the power supply means 20 and the operation mode is returned to smoking. It is detected at the beginning of each cycle whether the primary atomizer 10 is connected to the power supply means 20, and if so, the smoking detection is entered, by means of a conditional control of the air flow sensor 22, so as to achieve an optimal reduction of power consumption.
The frequency of execution and the time of the timed wake-up in the step S50 can be adjusted and set according to practical situations, and the time interval of the timed wake-up is preferably less than or equal to 500ms in the implementation.
Further in the implementation of step S50, when the airflow sensor 22 is controlled to detect the smoking airflow on the atomizer 10, the sensor has a signal peak at the moment of powering on, so in order to avoid misjudgment, when the detection signal of the sensor is acquired, the signal result in the section of the powering-on interval may be filtered/removed, and in the implementation, the delay of acquiring the detection signal is performed, and the delay time is adjusted accordingly according to the type of the flow sensor, manufacturer, response time, signal strength and other parameters. The delay time is preferably controlled to 2 to 5ms in practice based on the aspiration of the e-cigarette and the accurate detection of the intensity of the sensed data that prevents erroneous judgment.
Further, in the above power consumption control method of the present invention, if it is used for an integrated electronic cigarette product, the connection state of the atomizer 10 is always connected to the power supply device 20 during the execution of the steps, and the detection of the steps S40 and S51 is an unnecessary step; and there are no three mode changes, and the wake-up on standby requires the airflow sensor 22 and controller 23 to be always on, the effect of actually reducing power consumption may not be significant.
On the basis of the above low power consumption control method, the present invention further proposes an electronic cigarette product comprising the low power consumption control method for executing the above electronic cigarette, the structure of the electronic cigarette product can be seen from fig. 5 and 6, and the electronic cigarette product comprises an atomizer 10a and a power supply device 20a; wherein the power supply device 20a comprises a battery cell 21a and a controller 22a; according to the above description, the controller 22a includes a processing unit 221a, and the processing unit 221a is configured to perform the power consumption control method of the electronic cigarette described above.
In the implementation of the method, in order to detect and calculate the progressive effect on the power consumption control, an MCU controller is adopted to wake up once every 500 ms; the time for delayed acquisition of the signal result of the air flow sensor is 3ms, and the power supply cell capacity is 500mAh for example for test. The MCU in each hardware has the working power consumption of 2mA, the static power consumption of 4uA and the sensor power consumption of 10mA. The power consumption of the whole method is as follows:
The MCU wakes up every 500ms, outputs a 3ms high level, and the average dynamic current power consumption is I= (3/500) 12 mA=72 uA;
the capacity of the power supply battery core is 500mAh, and the EC capacity is 2/3 of the total capacity, and if the EC capacity C=500 (2/3) mAh=1000/3 mAh;
The powerable time is h=c/i=4630H, days d=h/24=192 days.
Therefore, it can be seen from the above that under the implementation of the method of the present invention, the hardware power consumption of the monitoring module when no smoke is drawn can be greatly eliminated, and the standby time can be prolonged to 192 days even when the battery core with the rated capacity of 500mAh is discharged for 2/3, so that the method is very suitable for the sensor with large power consumption to save the electric quantity.
It should be noted that the description of the invention and the accompanying drawings show preferred embodiments of the invention, but are not limited to the embodiments described in the description, and further, that modifications or variations can be made by a person skilled in the art from the above description, and all such modifications and variations are intended to fall within the scope of the appended claims.
