Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure. While the invention will be described in conjunction with the preferred embodiments, it is not intended that features of the invention be limited to these embodiments. On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been left out of the description in order to avoid obscuring or obscuring the focus of the present invention. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
It should be noted that in this specification, like reference numerals and letters refer to like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The invention provides an electronic cigarette control system which comprises a power consumption obtaining unit and a processing module, wherein the power consumption obtaining unit is used for obtaining the total power consumption accumulated by the heating device of an electronic cigarette from the first heating to the last heating. The accumulated total power consumption is the total energy consumed by the heating device in the electronic cigarette from the first time of use to the last time of use. The processing module is used for comparing the accumulated total power consumption with a power consumption threshold value, and controlling the heating device to be in a heating state if the accumulated total power consumption is smaller than the power consumption threshold value; and if the accumulated total power consumption is larger than or equal to the power consumption threshold, controlling the heating device to be in a state of being incapable of heating.
The heating device is a heat generating component for atomizing an aerosol generating substrate in an electronic cigarette, and for example, in an electronic cigarette for heating tobacco tar, the heating device is an atomizer. The power consumption threshold is a power consumption upper limit value, and may be a value set in advance, for example, a specific boundary value specified manually. In this embodiment, the limit value may be selected to be less than or equal to the power consumption value of the heating device when the heating device reaches the end of its service life. When the accumulated total power consumption is smaller than the power consumption threshold value, the heating device is in a heating-capable state, namely the electronic cigarette can also be controlled to electrify the heating device, and the heating device is in a state capable of being started, and the electronic cigarette can enable the heating device to generate heat after being started. When the accumulated total power consumption is greater than or equal to the power consumption threshold, the heating device is in a state of being incapable of heating, namely, the heating device can not perform atomization work any more. There are various ways for the processing module to control the heating device to be incapable of heating, for example, the heating device may be incapable of heating by controlling the electronic cigarette to be incapable of conducting power, or even if the electronic cigarette is powered but disconnected from the heating device, or the heating device itself is incapable of conducting power, or the heating device itself may be powered, but the processing module controls the heating device to be in a state of not generating heat. The heating device can not generate heat only by the control of the processing module after the total power consumption reaches the upper limit value.
In the conventional electronic cigarette with the counting function, when the number of suction openings of a user reaches a set value, a heating device in the electronic cigarette does not work any more, and at the moment, the user discards a cartridge containing the heating device in the electronic cigarette and replaces the cartridge with a new cartridge, so that the cartridge is prevented from being used beyond the limit. However, the amount of suction per puff varies from user to user and the consumption of the heating means also varies. Some people may need to pump 300 mouths to consume the tobacco tar, and some people may pump 200 mouths to consume the tobacco tar. Therefore, it is not accurate to first limit the life of the cartridge by the number of ports. For this reason, the existing upper limit of the number of the suction openings is generally conservative statistics, which means that when the upper limit of the number of the suction openings is reached, a user still has a lot of tobacco tar in the cartridge, and the cartridge is limited to be used again, resulting in a great waste.
The inventor of the present application has found that even when the tobacco tar in the cartridge is consumed, the heating device in the cartridge can still be used, for example, the service life of some ceramic atomizing cores can reach more than 2000 times of smoking, and the corresponding parameter influencing the service life of the heating device is the service power consumption of the heating device. When the energy consumed by the heating device reaches a certain value, the service life of the heating device can be reached. Before the heating device does not reach the life, the heating device can still continue to use in reality, and after the heating device reaches the life, if continue to use, easily make harmful substance produce in the electron cigarette flue gas, or in order to cause other safety problems.
According to the electronic cigarette control system, the energy consumed by the heating device is used as a measurement parameter of the service life of the cigarette cartridge, and even if the tobacco tar in the cigarette cartridge is used up, as long as the heating device can still be normally used, a user can continue to use the electronic cigarette control system in a mode of adding the tobacco tar by himself. When the consumed energy of the heating device reaches the upper limit, the heating device is controlled not to be used any more. Namely, the electronic cigarette control system can realize the maximum utilization of the heating device in the cigarette cartridge and can also avoid the risk of harmful substance suction caused by overuse of repeated use.
Further, the power consumption obtaining unit includes, for example: the electronic cigarette heating device comprises a voltage detection module, a current detection module, a timing module and a power consumption calculation module, wherein the voltage detection module is used for detecting voltages at two ends of a heating device in the electronic cigarette, the current detection module is used for detecting current passing through the heating device, the timing module is used for detecting heating time of the electronic cigarette, the power consumption calculation module is used for calculating power consumption of the heating device according to the detected voltage, current and heating time, and then the power consumption obtaining unit obtains total power consumption accumulated by the heating device according to the power consumption. The cumulative total power consumption is a superposition of the energy consumed by the user after multiple uses. Fig. 1 shows a control system of an electronic cigarette partially showing the present embodiment, which includes a current detection module, a voltage detection module, a timing module and a processing module, wherein the power consumption calculation module mentioned in the above embodiments may be provided separately, or may be integrated with the processing module in a circuit board, for example, the power consumption calculation module and the processing module are integrated in a processor. In addition, the power consumption calculating module, the processing module and other modules may also be integrated into one chip, and the invention is not limited herein. Fig. 1 shows a schematic diagram of an electronic cigarette control system, in which a display module may be used to display accumulated power consumption information, and may also display information such as whether a used cigarette cartridge is normal, whether charging is required, and a charging status. Figure 2 schematically illustrates a modular layout of the circuit boards in the cigarette rod. The current detection module, the voltage detection module, the timing module, the power consumption calculation module and the processing module are integrated in one PCB and are communicated with other PCBs or chips through communication interfaces.
In other embodiments, the power consumption obtaining unit may also include a voltage detecting module, a timing module, and a power consumption calculating module, and the calculation of the power consumption may be calculated according to the voltage, the resistance of the heating device, and the heating time. For example, if the resistance of the porous ceramic or the heating wire in the heating device is 3.2 Ω, the voltage across the heating device is 4.5V, and the heating time is 3s, the power consumption calculation formula in the time is (U)2/R)*t=(4.523.2) × 3 ═ 18.98J. And the previous power consumption is added, so that the total power consumption of the current heating device is obtained.
In other embodiments, the power consumption obtaining unit may further include a current detecting module, a timing module, and a power consumption calculating module, and the calculation of the power consumption may be calculated according to the current, the resistance of the heating device, and the heating time. For example, if the current flowing through the heating device is 1.6A, the resistance of the heating cylinder in the heating device is 4 Ω, and the heating time is 2.5s, the calculation formula of the power consumption in the time is I2*R*t=1.624 × 2.5 ═ 25.6J. And the previous power consumption is added, so that the total power consumption of the current heating device is obtained.
Further, the power consumption calculating module is used for calculating the power consumed by the heating device under each suction of the user, and the power obtaining unit further accumulates the power consumption of each suction to obtain the accumulated total power consumption.
In each of the above embodiments, the power consumption obtaining unit further includes a power consumption storage module, where the power consumption storage module is configured to store total power consumption data accumulated when the heating device is heated and used, the processing module is configured to compare the total power consumption data stored in the storage module with a power consumption threshold, and if the stored total power consumption data reaches the power consumption threshold, the instruction heating device cannot continue to operate, and the processing module controls the electronic cigarette not to be heated. When a new cigarette cartridge is replaced, namely a new heating device is replaced, the processing module judges that the total power consumption data at the moment does not reach the power consumption threshold value, and the electronic cigarette can be controlled to continue heating.
Each module in the power consumption obtaining unit may be integrated in one circuit board, or may be distributed in different circuit boards. For example, the power consumption calculating module and the power consumption storage module may be integrated in a PCB, or the power consumption storage module may be disposed in a chip, the chip is fixed on the cartridge, and the power consumption calculating module is disposed in a circuit board in the cigarette rod.
In each of the above embodiments, the power consumption storage module is configured to add the total power consumption data generated last time and the new power consumption data obtained through calculation, generate and store the final accumulated total power consumption data, and delete the total power consumption data generated last time. That is, the power consumption storage module deletes old data and retains only the newly accumulated power consumption data. In addition, when the accumulated total power consumption is greater than or equal to the power consumption threshold value, the power consumption storage module stops updating the total power consumption data. The power consumption storage module can be positioned on the cigarette cartridge, when the heating device reaches the service life, the power consumption storage module does not update data any more, the whole cigarette cartridge can be replaced, and correspondingly the new cigarette cartridge is provided with the power consumption storage module for recording the use power consumption data of the cigarette cartridge.
In each of the above embodiments, if the accumulated total power consumption is greater than or equal to the power consumption threshold, the processing module controls to stop energizing the heating device and to lock the heating device, thereby further strengthening the limitation on the use of the heating device.
In each of the above embodiments, the electronic cigarette control system further includes an identification module, configured to read an identification code of the heating device, and control the heating device to be in a non-heatable state if the identification code read by the identification module is incorrect, and control the heating device to be in a heatable state if the identification code read by the identification module is correct. The heating device will have an identification code and if the heating device is not part of the manufacturer, and is of a product to be protected from counterfeiting, the processing module will prevent the use of such a counterfeit heating device by identification by the identification module, such that it is in a non-heatable state, e.g. not energized or controlled so that electrical energy does not flow through the heating device. When the identification identity code on the heating device is identified successfully, the heating device belongs to a regular heating device of a manufacturer, and the processing module controls the heating device to be heated. Through encrypting heating device, set up the discernment identity code, the counterfeit product that can prevent to imitate and duplicate uses, also can avoid DIY player to explain by oneself, causes heating device overuse.
In the above embodiments, the ID code may be independent and non-repetitive, i.e. specific to each heating device, such that each heating device is equivalent to having a specific ID, and by identifying the independent and non-repetitive ID code, parameters and usage conditions are obtained that are also specific to the heating device.
In the above embodiments, the various modules may be located in different circuit boards respectively, or may be integrated into one circuit board. For example, the voltage detection module, the current detection module, the timing module, the identification module and the processing module may be integrated in a PCB, the power consumption calculation module and the power consumption storage module may be integrated in a chip, the chip may be fixedly connected to a cartridge equipped with a heating device, a power consumption threshold and an identification code may be written in the chip, and the chip may be electrically connected to the PCB. Along with the transfer of the cigarette cartridge, the identification identity code, the power consumption threshold value, the power consumption storage module and the power consumption calculation module are transferred along with the transfer of the cigarette cartridge. In other embodiments, the power consumption storage module may be incorporated into a chip on the cartridge, in which the power consumption threshold and the identification code are written.

In the above embodiments, the timing module is a timer circuit, and can be implemented by a single chip microcomputer.
The invention also provides an electronic cigarette comprising the electronic cigarette control system in each embodiment.
As shown in fig. 3A to 3C and fig. 4A to 4C, the structure of an electronic cigarette including an electronic cigarette control system is exemplarily shown, which includes asuction nozzle 11, acigarette rod 12, abattery 13 and a chargingboard 14 disposed inside the cigarette rod, and aPCB 15.
Figures 3A-3C show a first embodiment of an electronic cigarette, the cartridge having acartridge housing 21 with asmoke channel 22 therein and a reservoir for an aerosol-forming substrate (e.g. tobacco tar), in this embodiment an oil-filledcavity 23, in which oil-filledcavity 23 the tobacco tar is stored. The heat-generatingbody 24 atomizes the tobacco tar from theoil filling chamber 23. When the tobacco tar is consumed, the tobacco tar can be repeatedly added into theoil filling cavity 23 and sealed by theoil cavity plug 25. The smoke cartridge is provided with achip 27, for example, thechip 27 is provided with a power consumption storage module, thechip 27 writes a power consumption threshold value and an identification identity code belonging to theheating body 24, and establishes communication connection with thePCB 15, thePCB 15 calculates the detected voltage, current and time to obtain a power consumption value, then transmits the power consumption value information to thechip 27, and the power consumption storage module in thechip 27 accumulates the obtained latest power consumption value into the original power consumption value to obtain accumulated total power consumption, and stores the accumulated total power consumption in thechip 27. The electronic cigarette can be continuously used by adding tobacco tar until theheating body 24 reaches the service life, and when the accumulated power consumption counted on thechip 27 reaches the power consumption threshold, the processing module on thePCB 15 controls the electronic cigarette to be in a state that the electronic cigarette cannot be heated. And then replacing the cigarette cartridge, and when the electronic cigarette control system detects that the power consumption of thenew heating body 24 does not reach the power consumption threshold value of theheating body 24, controlling the electronic cigarette to be in a heating state by the processing module.
Fig. 4A to 4C show a second embodiment of an electronic cigarette, in which the cartridge has acartridge housing 21 with asmoke channel 22 inside, but the difference is that the reservoir of this embodiment is a separate replaceable part, for example, the reservoir of this embodiment has an integrallyreplaceable oil bottle 26, which is inserted into anoil filling chamber 23. The smoke cartridge is provided with achip 27, for example, thechip 27 is provided with a power consumption storage module, thechip 27 writes a power consumption threshold value and an identification identity code belonging to theheating body 24 and establishes communication connection with thePCB 15, thePCB 15 calculates voltage, current and time information obtained by detection to obtain a power consumption value and transmits the power consumption value to thechip 27, and the power consumption storage module in thechip 27 accumulates the obtained latest power consumption value into the original power consumption value to obtain accumulated total power consumption and stores the accumulated total power consumption into thechip 27. After the tobacco tar is consumed, theold oil bottle 26 in the cartridge can be taken out to replace anew oil bottle 26, so that the cartridge can be continuously used until theheating body 24 reaches the service life, the accumulated power consumption counted on thechip 27 reaches the power consumption threshold, and the processing module on thePCB 15 can control the electronic cigarette to be in a state that the electronic cigarette cannot be heated. And then replacing the whole cigarette cartridge, and controlling the electronic cigarette to be in a heating state by the processing module when the electronic cigarette control system detects that the power consumption of thenew heating body 24 does not reach the power consumption threshold value of theheating body 24.
Set up the chip on the cigarette bullet, compare in PCB circuit board, the volume is littleer, and the chip contact is circular telegram promptly, and signal transmission is comparatively convenient. The chip at least comprises the power consumption storage module, and after the smoke cartridge is transferred, the consumed energy of the device is still counted in the chip and can be obtained.
In addition, in the electronic cigarette according to each of the above embodiments, thechip 27 located on the cartridge is fixed to the outside of the cartridge, for example, provided on the outer surface of the cartridge. When the chip is installed outside the smoke cartridge, the chip is an independent installation structure and is not connected with the inside of the smoke cartridge through a circuit and the structure. The device is more convenient, saves the internal volume of the smoke cartridge, can avoid the corrosion of tobacco tar, water vapor and the like to electronic components, and ensures the stable product quality. . Thechip 27 of this embodiment is disposed on the outer surface of the bottom of the cartridge housing and is electrically connected to thetobacco rod 12.
Further, the chip may be one or more. When the electronic cigarette needs a chip with a large storage space, a plurality of chips with small storage spaces can be arranged to meet the storage requirement. This is because a plurality of chips with small storage capacity sometimes costs less than one chip with large storage capacity. When there are a plurality of chips, the chip sequence can be read by thePCB 15, and then the data priority is defined according to the chip sorting information. The measurement limit of the chip is a set energy value, and the number of times of unfixed times is set according to the service life of theheating element 14. In addition, the chip write setting has a lock-up function, and cannot be edited and secondarily developed after being shipped. The chip is mounted on the cartridge, and after the chip is mounted in place, the electrode of theheating body 14 and the chip contact are in a connected state at the same time. Further, contact channels may be reserved on the chip.
At least one data channel is arranged in the chip, more than one data channel can be arranged, and the data channels have a sequence when being written or read. Each data channel may perform a count, which may be zero followed by termination of circuit activation or entry into the next channel count.
Referring to fig. 5, the present invention further provides an electronic cigarette control method, including the following steps: obtaining the total power consumption accumulated by the heating device of the electronic cigarette from the first heating to the last heating; comparing the accumulated total power consumption with a power consumption threshold, and controlling the heating device to be in a heating state if the accumulated total power consumption is smaller than the power consumption threshold; and if the accumulated total power consumption is larger than or equal to the power consumption threshold value, controlling the heating device to be in a state of being incapable of heating.
The heating device at least comprises a device capable of generating heat, such as a heating wire, a heating column and an atomizer. Is a device for heating an aerosol-forming substrate (e.g. tobacco tar or solid tobacco) to generate smoke in an electronic cigarette.
As described above, the power consumption threshold is the power consumption upper limit value, and may be a value set in advance, for example, a specific boundary value specified manually. In this embodiment, the limit value may be selected to be less than or equal to the power consumption value of the heating device when the heating device reaches the end of its service life. When the accumulated total power consumption is smaller than the power consumption threshold value, the heating device is in a heating-capable state, namely the electronic cigarette can also be controlled to electrify the heating device, and the heating device is in a state capable of being started, and the electronic cigarette can enable the heating device to generate heat after being started. When the accumulated total power consumption is greater than or equal to the power consumption threshold, the heating device is in a state of being incapable of heating, namely, the heating device can not perform atomization work any more.
For example, the heating device may be disabled to heat by controlling the electronic cigarette to be disabled to energize, or the electronic cigarette may be powered but disconnected from the heating device, or the heating device itself may not be powered, or the heating device itself may be powered but may be controlled to be in a state of not generating heat. It is sufficient that the heating device is controlled not to generate heat after the total power consumption reaches the upper limit value.
Further, obtaining the total power consumption accumulated when the heating device of the electronic cigarette is used for heating comprises: detecting the voltage at two ends of a heating device in the electronic cigarette, detecting the current passing through the heating device, detecting the heating time of the electronic cigarette, and calculating the power consumption of the heating device according to the detected voltage, current and heating time. In other embodiments, power consumption may also be obtained by voltage, resistance, and time. For example, the voltage at two ends of a heating device in the electronic cigarette is detected, the time for heating the electronic cigarette is detected, and the power consumption of the heating device is calculated and obtained according to the detected voltage, the time for heating and the resistance of the heating device. Or, the current passing through the heating device is detected, the time for heating the electronic cigarette is detected, and the power consumption of the heating device is calculated and obtained according to the detected current, the time for heating and the resistance of the heating device. And then, obtaining the total power consumption accumulated by the heating device according to the power consumption of the heating device each time.
The power consumption of the electronic cigarette at each time can be calculated by taking the power consumption of each mouth of the user for suction as a calculation unit, and then accumulated to obtain the accumulated total power consumption. Namely, the power consumed by the heating device when each port of the user sucks is calculated, and then the power consumption of each port is accumulated to obtain the accumulated total power consumption.
In the control method according to each of the above embodiments, the total power consumption data accumulated when the heating device is used for heating is stored, the stored total power consumption data is compared with the power consumption threshold, and whether the heating device can perform heating is controlled based on the comparison result.
In the aspect of data storage, the total power consumption data generated last time is added with the new power consumption data obtained through calculation, the finally accumulated total power consumption data is generated and stored, and the total power consumption data generated last time is deleted. In the embodiment of the electronic cigarette, the chip deletes the old data and records only the latest total power consumption data.
Specifically, when the accumulated total power consumption is greater than or equal to the power consumption threshold, the update of the total power consumption data is stopped. If the accumulated total power consumption is greater than or equal to the power consumption threshold, the control unit stops energizing the heating unit and locks the heating unit.
In the control method of each of the above embodiments, the method further includes: and reading the identification code of the heating device, controlling the heating device to be in a non-heatable state if the read identification code is incorrect, and controlling the heating device to be in a heatable state if the read identification code is correct. So can prevent the counterfeit product use of imitation and duplication, also can avoid DIY player to explain by oneself, cause heating device overuse.
The control method of the present invention will be described below using specific data and with a specific structure, but the present invention is not limited thereto.
The battery discharge output current is A, the real-time voltage at the two ends of the heating device is V, and the discharge time is T.
The voltage and current for the general electronic cigarette to be heated by electrification are stable, so the word energy output value is as follows: and A V T, the accumulated output is as follows: a1 × V1 × T1+ a2 × V2 × T2+ A3 × V3 × T3+. + An × Vn × Tn. When the integrated value is added to a A0V 0T 0, it is determined that the metering is terminated and the discharge is not continued. A, V, T can be set to be non-constant value, and the value generated each time A V T can be constant value or variable value, and is controlled by chip or PCB to perform accumulation measurement.
The control of whether the heating device is in a heatable state can employ one of two logics:
accumulation count logic one: the chip sets up the power consumption threshold value, and PCB circuit board output is write in and is accumulated, stops the cigarette bullet to use after reaching the power consumption threshold value.
And accumulating the count logic two: the number of times is counted by the chip, the PCB is provided with a power consumption threshold value for accumulation, after the power consumption threshold value is reached, the chip responds and does not count for the next time, and the service life of the smoke bomb is reached.
The method for calculating the accumulated power consumption of the current heating device comprises the following steps: and P T, calculating a power consumption reference value by multiplying the instant power by the power-on time, and taking the power consumption reference value as a power consumption threshold value. If the test voltage is 4.2V, the resistance value is 2.5 omega, and when the service life is reached, the accumulated power-on time is 200min, the current accumulated power consumption can be calculated as follows: (4.2 × 4.2/2.5) × 6000s, yielding the power consumption reference value: 42336. then, the power consumption threshold of this type of heating device may be set to 42336. The power consumption threshold may be set to the above power consumption reference value, but may not be exceeded.
The calculation method of the power consumption accumulation is single calculation, for example:
1 st port: (4.2 × 4.2/2.5) × 5s ═ 35.28
And a2 nd port: (4.2 × 4.2/2.5) × 3s ═ 21.17
And port 3: (4.2 × 4.2/2.5) × 4s ═ 28.23
And so on.
After the first suction, generating a power consumption reference value of 38.25 and writing the power consumption reference value into the smoke bomb chip, and after the second suction, accumulating the generated power consumption reference value and the written data, wherein the written value is 56.54; the third port pumping is complete and a value of 84.68 is written, and so on.
When writing data, adding the newly generated single data and the recorded final accumulated data to generate new final accumulated data, and writing the new final accumulated data into the chip after deleting the old data. The data ultimately stored on the chip is the sum of the data generated by all previous puffs after the last puff. When this data exceeds 42336, the heating device cannot be energized again, and is locked, and the heating device cannot be used continuously.
The service life of the heating device is determined according to different materials, types, resistance values and the like of the selected heating device, so that different expected service lives exist. The heating device may be a porous ceramic, hydroxyapatite, sintered metal powder, or woven metal wire felt. The resistance value is between 0.2 omega and 5.0 omega. Or may be a pre-embedded metal wire such as nichrome, nickel, stainless steel, etc.; or may be a printed circuit; or a corroded metal mesh sheet with lines.
The service life of the heating device is determined by measuring, and the heating device is electrified to work under a preset voltage, so that the heating device cannot stably output power, or scorching substances are generated at the heating part of the heating device, namely the service life is reached.
The method can also be used for testing the smoke of the electronic cigarette, and the highest limited standard of harmful substances (carbon monoxide, heavy metals, carbonyl compounds and the like) in the smoke of the electronic cigarette is reached, namely the service life is reached. I.e. scrapped once the defined criteria are exceeded.
