In one embodiment, as shown in FIGS. 1 to 4 , an electronic cigarette atomization control device is provided, which includes an oil storage member 10, an atomizer assembly 20, and a controller 30. The oil storage member 10 is used to store cigarette oil, and the oil storage member 10 includes a first end and a second end opposite to the first end; the atomizer assembly 20 includes at least a first atomizer 210 and a second atomizer 220, the first atomizer 210 is arranged near the first end, and the first atomizer 210 is configured to atomize the cigarette oil stored near the first end; the second atomizer 220 is arranged near the second end, and the second atomizer 220 is configured to atomize the cigarette oil stored near the second end; the controller 30 is connected to the first atomizer 210 and the second atomizer 220 respectively; the controller 30 is configured to switch the first atomizer 210 and the second atomizer 220 to start.

The oil storage part 10 can be used to store tobacco oil, and the ingredients of tobacco oil can be, but are not limited to, edible or medical grade glycerol (also known as glycerin), propylene glycol, polyethylene glycol, nicotine, and tobacco flavors. The oil storage part 10 can be a hollow annular structure, for example, the oil storage part 10 can be a hollow cylindrical structure, and the atomizer assembly 20 is arranged in the hollow cylindrical structure of the oil storage part 10. The oil storage part 10 can be oil storage cotton, which can absorb and store tobacco oil. The oil storage part 10 includes a first end and a second end, and the first end corresponds to the second end. For example, the oil storage component 10 can be divided into a first oil storage area and a second oil storage area, the first end is located in the first oil storage area, the second end is located in the second oil storage area, the first atomizer 210 is located in the first oil storage area, and the atomizing end of the first atomizer 210 is attached to the inner wall of the first oil storage area, so that the first atomizer 210 can atomize the oil in the first oil storage area according to the trigger transmission of the controller 30; the second atomizer 220 is located in the second oil storage area, and the atomizing end of the second atomizer 220 is attached to the atomizing end of the second oil storage area, so that the second atomizer 220 can atomize the oil in the second oil storage area according to the trigger of the controller 30.

The atomizer assembly 20 includes at least a first atomizer 210 and a second atomizer 220. It should be noted that the number of atomizers can be determined based on the size of the oil storage member 10. For example, the atomizer assembly 20 can also include a third atomizer or a fourth atomizer. Exemplarily, the atomizer assembly 20 may include a first atomizer 210, a second atomizer 220, and a third atomizer. The first atomizer 210, the second atomizer 220, and the third atomizer can be arranged at equal intervals in the hollow structure of the oil storage member 10. The first atomizer 210 is arranged near the first end of the oil storage member 10, and the second atomizer 220 is arranged near the second end of the oil storage member 10.

The controller 30 can be used to switch the first atomizer 210 and the second atomizer 220 to start. For example, the controller 30 can pre-load an existing program to identify the number of puffs of the user's electronic cigarette, and then obtain the number of puffs. Further, the controller 30 can compare the number of puffs with the preset number threshold based on the existing computer program. When the number of puffs is less than the preset number threshold, the first atomizer 210 is switched to start, and then the first atomizer 210 starts the atomization function, atomizes the smoke oil near the first end of the oil storage member 10, and then generates atomized gas for the user to inhale. When the number of puffs is greater than or equal to the preset number threshold, the controller 30 switches the second atomizer 220 to start, and then the second atomizer 220 starts the atomization function, atomizes the smoke oil near the second end of the oil storage member 10, and then generates atomized gas for the user to inhale, so as to avoid the later stage of the use of the electronic cigarette, when the smoke oil content near the first end of the oil storage member 10 is reduced, affecting the content of the generated atomized gas, and can improve the consistency of the user's inhalation taste.

Exemplarily, when a user uses the electronic cigarette for the first time, the controller 30 directly controls the first atomizer 210 to start by default, and then directly activates the first atomizer 210 to perform atomization, thereby simplifying the atomization control process.

In the above embodiment, the oil storage member 10 is used to store the tobacco oil, and the oil storage member 10 includes a first end and a second end opposite to the first end; the atomizer assembly 20 includes at least a first atomizer 210 and a second atomizer 220, the first atomizer 210 is arranged near the first end, and the second atomizer 220 is arranged near the second end, and the controller 30 is connected to the first atomizer 210 and the second atomizer 220 respectively; the controller 30 is configured to switch the first atomizer 210 and the second atomizer 220 to start, such as when the first atomizer 210 is switched to start, the first atomizer 210 atomizes the tobacco oil stored near the first end; for example, when the second atomizer 220 is switched to start, the second atomizer 220 is configured to atomize the tobacco oil stored near the second end, so as to achieve stable and reliable electronic cigarette atomization. The present application achieves stable generation of aerosol e-liquid atomization content by arranging two atomizers close to the two ends of the oil storage member 10, and switching the first atomizer 210 or the second atomizer 220 through the controller 30, thereby improving the consistency of the user's smoking taste, enhancing the smoking taste experience and the overall product experience, and meeting user needs.

In one embodiment, as shown in FIGS. 1 to 4 , an electronic cigarette atomization control device is provided, which includes an oil storage member 10, an atomizer assembly 20, and a controller 30. The oil storage member 10 is used to store cigarette oil, and the oil storage member 10 includes a first end and a second end opposite to the first end; the atomizer assembly 20 includes at least a first atomizer 210 and a second atomizer 220, and the first atomizer 210 is arranged near the first end, and the first atomizer 210 is configured to receive a first control signal, and according to the first control signal, to The e-liquid is atomized; the second atomizer 220 is arranged near the second end, and the second atomizer 220 is configured to receive the second control signal and atomize the e-liquid according to the second control signal; the controller 30 is connected to the first atomizer 210 and the second atomizer 220 respectively; the controller 30 is configured to identify the number of puffs of the user's electronic cigarette, and according to the result of the identification, when the number of puffs is less than a preset number threshold, transmit the first control signal to the first atomizer 210, and when the number of puffs is greater than or equal to the preset number threshold, transmit the second control signal to the second atomizer 220.

For example, the oil storage component 10 can be divided into a first oil storage area and a second oil storage area, the first end is located in the first oil storage area, the second end is located in the second oil storage area, the first atomizer 210 is located in the first oil storage area, and the atomizing end of the first atomizer 210 is attached to the inner wall of the first oil storage area, and then the first atomizer 210 can atomize the tobacco oil in the first oil storage area according to the first control signal transmitted by the controller 30; the second atomizer 220 is located in the second oil storage area, and the atomizing end of the second atomizer 220 is attached to the inner wall of the second oil storage area, and then the second atomizer 220 can atomize the tobacco oil in the second oil storage area according to the second control signal transmitted by the controller 30.

The controller 30 can be used to identify the number of puffs of the user's electronic cigarette. For example, the controller 30 may include a counting unit and an airflow sensing unit. The airflow sensing unit can be used to detect whether gas flow is generated in the electronic cigarette. If the airflow sensing unit detects gas flow, it is determined that the user is puffing the electronic cigarette. The counting unit can be used to count the number of times the airflow sensing unit detects gas flow, and then the number of puffs of the user's electronic cigarette can be obtained. Furthermore, the controller 30 can compare the number of puffs, and when the number of puffs is less than a preset number threshold, the first control signal is transmitted to the first atomizer 210, and then the first atomizer 210 starts the atomization function, atomizes the tobacco oil near the first end of the oil storage member 10, and then generates atomized gas for the user to inhale. When the number of puffs is greater than or equal to a preset number threshold, the controller 30 transmits a second control signal to the second atomizer 220, and then the second atomizer 220 starts the atomization function, atomizes the tobacco oil near the second end of the oil storage member 10, and then generates atomized gas for the user to inhale, thereby avoiding the situation in which the tobacco oil content near the first end of the oil storage member 10 decreases in the later stage of the use of the electronic cigarette, affecting the content of the generated atomized gas, and improving the consistency of the user's inhalation taste.

It should be noted that when a user uses the electronic cigarette for the first time, the controller 30 directly transmits the first control signal to the first atomizer 210 by default, thereby directly activating the first atomizer 210 to perform atomization without first identifying the number of puffs, thereby simplifying the atomization control process.

In the above embodiment, by placing the first atomizer 210 close to the first end, the second atomizer 220 The controller 30 is arranged near the second end and is connected to the first atomizer 210 and the second atomizer 220 respectively; the controller 30 identifies the number of puffs of the user's electronic cigarette, and based on the result of the identification, when the number of puffs is less than a preset number threshold, transmits a first control signal to the first atomizer 210, and then the first atomizer 210 receives the first control signal and atomizes the e-liquid according to the first control signal; the controller 30 transmits a second control signal to the second atomizer 220 when the number of puffs is greater than or equal to the preset number threshold, and then the second atomizer 220 receives the second control signal and atomizes the e-liquid according to the second control signal, thereby realizing stable and reliable electronic cigarette atomization control. The present application arranges two atomizers respectively at the two ends of the oil storage member 10, detects the number of puffs of the user's electronic cigarette by the controller 30, and switches the first atomizer 210 or the second atomizer 220 according to whether the number of puffs meets a preset threshold, thereby achieving a stable aerosol-generated e-liquid atomization content, improving the consistency of the user's smoking taste, enhancing the smoking taste experience and the overall product experience, and meeting user needs.

In one embodiment, as shown in FIG. 3 , the controller 30 includes a processing chip 310 , an airflow sensor 320 , and a counter 330 ; the processing chip 310 is connected to the airflow sensor 320 , the counter 330 , the first atomizer 210 , and the second atomizer 220 , respectively.

Among them, the processing chip 310 can be but not limited to a single-chip microcomputer chip. The airflow sensor 320 can be used to detect whether gas flow is generated in the electronic cigarette. If the airflow sensing unit detects gas flow, it is determined that the user is inhaling the electronic cigarette. The counter 330 can be used to count the number of times the airflow sensing unit detects gas flow, and then the number of puffs of the user's electronic cigarette can be obtained. Further, based on the processing chip 310 being respectively connected to the airflow sensor 320, the counter 330, the first atomizer 210 and the second atomizer 220, the processing chip 310 can receive the number of puffs transmitted by the counter 330, and then the number of puffs can be compared and processed. When the number of puffs is less than the preset number threshold, the first atomizer 210 is switched to start, and then the first atomizer 210 starts the atomization function, and the tobacco oil near the first end of the oil storage part 10 is atomized, and then the atomized gas is generated for the user to inhale. When the number of puffs is greater than or equal to a preset number threshold, the processing chip 310 switches the second atomizer 220 to start, and then the second atomizer 220 starts the atomization function, atomizes the tobacco oil near the first end of the oil storage component 10, and then generates atomized gas for the user to inhale, thereby avoiding the situation in the later stage of electronic cigarette use where the tobacco oil content near the first end of the oil storage component 10 decreases, affecting the content of the generated atomized gas, and improving the consistency of the user's inhalation taste.

In one embodiment, as shown in FIG. 3 , the controller 30 further includes a timer 340 ; the timer 340 is connected to the processing chip 310 .

Among them, the timer 340 can be used to count the cumulative puffing time of the user's electronic cigarette. For example, the airflow sensor 320 can be used to detect whether gas flow is generated inside the electronic cigarette, and then determine whether the user is puffing the electronic cigarette. When it is determined that the user is puffing the electronic cigarette, the timer 340 is triggered to start, and the length of time the user puffs the electronic cigarette is counted until it is detected that the user stops puffing the electronic cigarette, and then the current puffing time is obtained. By accumulating the puffing time of each time, the cumulative puffing time of the user's electronic cigarette is obtained.

The processing chip 310 can compare and process the number of puffs and the cumulative puff time respectively. When the cumulative puff time is less than the preset time threshold or the number of puffs is less than the preset number threshold, the first atomizer 210 is switched on, and then the first atomizer 210 starts the atomization function, atomizes the oil near the first end of the oil storage part 10, and then produces atomized gas for the user to inhale, so as to avoid the oil content near the first end of the oil storage part 10 in the later stage of the use of the electronic cigarette, which affects the content of the atomized gas, and can improve the consistency of the user's inhalation taste. When the cumulative puff time is greater than or equal to the preset time threshold and the number of puffs is greater than or equal to the preset number threshold, the processing chip 310 switches the second atomizer 220 to work, and then the second atomizer 220 starts the atomization function, atomizes the oil near the second end of the oil storage part 10, and then produces atomized gas for the user to inhale. The present application sets an airflow sensor 320, a timer 340 and a counter 330, and switches the first atomizer 210 and the second atomizer 220 on and off according to whether the accumulated puffing time and the number of puffs meet the conditions, thereby further improving the accuracy of the electronic cigarette atomization control, achieving a stable aerosol atomization content of the e-liquid, improving the consistency of the user's smoking taste, enhancing the smoking taste experience and the overall product experience, and meeting user needs.

In one example, as shown in FIG1 , the first end of the oil storage member 10 is disposed near the mouthpiece of the electronic cigarette. The user smokes the electronic cigarette by drawing on the mouthpiece. By disposing the first end of the oil storage member 10 near the mouthpiece of the electronic cigarette, that is, disposing the first atomizer 210 near the mouthpiece, when the number of puffs is less than a preset threshold, a first control signal is transmitted to the first atomizer 210, and then the first atomizer 210 starts the atomization function, atomizes the oil near the first end of the oil storage member 10, and then generates atomized gas for the user to inhale. By controlling the first atomizer 210 near the mouthpiece to perform atomization when the number of puffs does not reach the preset threshold, the transmission path of the airflow can be shortened, and at the same time, the first end of the oil storage member 10 near the mouthpiece can be atomized in advance in the early stage of the use of the electronic cigarette, thereby improving the user's smoking taste.

In one example, the controller 30 is further configured to identify the cumulative duration of the user's puffs on the electronic cigarette. And according to the result of the identification, when the cumulative puff time is less than the preset time threshold or the number of puffs is less than the preset number threshold, the first control signal is transmitted to the first atomizer 210, and when the cumulative puff time is greater than or equal to the preset time threshold and the number of puffs is greater than or equal to the preset number threshold, the second control signal is transmitted to the second atomizer 220.

The controller 30 may also include a timer, which can be used to count the cumulative puffing time of the user's electronic cigarette. For example, the airflow sensor can be used to detect whether gas flow is generated inside the electronic cigarette, thereby determining whether the user is puffing the electronic cigarette. When it is determined that the user is puffing the electronic cigarette, the timer is triggered to start, and the time for the user to puff the electronic cigarette is counted until it is detected that the user stops puffing the electronic cigarette, thereby obtaining the current puffing time. By accumulating the puffing time of each time, the cumulative puffing time of the user's electronic cigarette is obtained.

The controller 30 can compare the number of puffs and the cumulative puff time respectively. When the cumulative puff time is less than the preset time threshold or the number of puffs is less than the preset number threshold, the controller 30 transmits a first control signal to the first atomizer 210, and then the first atomizer 210 starts the atomization function, atomizes the oil near the first end of the oil storage member 10, and then generates atomized gas for the user to inhale, so as to avoid the oil content near the first end of the oil storage member 10 decreasing in the later stage of the electronic cigarette use, which affects the content of the atomized gas generated, and can improve the consistency of the user's inhalation taste. When the cumulative puff time is greater than or equal to the preset time threshold and the number of puffs is greater than or equal to the preset number threshold, the controller 30 transmits a second control signal to the second atomizer 220, and then the second atomizer 220 starts the atomization function, atomizes the oil near the second end of the oil storage member 10, and then generates atomized gas for the user to inhale. The present application identifies the cumulative puffing time and the number of puffs of the user's electronic cigarette, and controls the on and off of the first atomizer 210 and the second atomizer 220 according to whether the cumulative puffing time and the number of puffs meet the conditions, thereby further improving the accuracy of the electronic cigarette atomization control, achieving a stable aerosol atomization content of the e-liquid, improving the consistency of the user's smoking taste, enhancing the smoking taste experience and the overall product experience, and meeting user needs.

In one example, the controller 30 is further configured to turn off the first atomizer 210 and transmit a second control signal to the second atomizer 220 when the accumulated puff time is greater than or equal to a preset time threshold and the number of puffs is greater than or equal to a preset number threshold.

The controller 30 can compare the number of puffs and the cumulative puff time respectively, and according to the processing result, when the cumulative puff time is greater than or equal to the preset time threshold and the number of puffs is greater than or equal to the preset number threshold, it is determined that the remaining amount of the smoke oil stored near the first end of the oil storage member 10 is low, and then the first end of the oil storage member 10 is turned off. The atomizer 210 transmits a second control signal to the second atomizer 220, so as to switch from the first atomizer 210 to the second atomizer 220 for atomizing the e-liquid, so that in the later stage of the user smoking the electronic cigarette, the aerosol e-liquid atomization content can still be stably generated, thereby improving the consistency of the user's smoking taste. At the same time, by turning off the first atomizer 210, electric energy can be saved, and the service life of the electronic cigarette can be increased without affecting the user's smoking taste.

In one embodiment, as shown in FIG. 4 , the first atomizer includes a first atomization drive circuit 212 and a first atomization core 214 ; the second atomizer includes a second atomization drive circuit 222 and a second atomization core 224 ; the first atomization drive circuit 212 is respectively connected to the first atomization core 214 and the controller; the second atomization drive circuit 222 is respectively connected to the second atomization core 224 and the controller.

The first atomization drive circuit 212 can be used to drive the first atomization core 214 to work, and the first atomization core 214 can be used to heat and vaporize the smoke oil near the first end of the oil storage member to generate mist particles.

The second atomization drive circuit 222 can be used to drive the second atomization core 224 to work, and the second atomization core 224 can be used to heat and vaporize the smoke oil near the second end of the oil storage member to generate mist particles. For example, the second atomization core 224 can be, but not limited to, a ceramic atomization core.

Based on the first atomization drive circuit 212, the first atomization core 214 and the controller are respectively connected; the second atomization drive circuit 222 is respectively connected to the second atomization core 224 and the controller, so that the controller can identify the number of puffs of the user's electronic cigarette, and compare the number of puffs. When the number of puffs is less than the preset number threshold, the first control signal is transmitted to the first atomization drive circuit 212, and then the first atomizer drive circuit drives the first atomization core 214 to work according to the first control signal, so that the first atomization core 214 starts the atomization function, atomizes the tobacco oil near the first end of the oil storage component, and then generates atomized gas for the user to inhale. When the number of puffs is greater than or equal to a preset number threshold, the controller transmits a second control signal to the second atomization drive circuit 222, and then the second atomization drive circuit 222 drives the second atomization core 224 to work according to the second control signal, so that the second atomization core 224 starts the atomization function, atomizes the tobacco oil near the second end of the oil storage component, and then generates atomized gas for the user to inhale, thereby avoiding the situation in which the tobacco oil content near the first end of the oil storage component decreases in the later stage of the use of the electronic cigarette, affecting the content of the generated atomized gas, which can improve the consistency of the user's inhalation taste and achieve a stable tobacco oil atomization content for generating aerosols.

Exemplarily, as shown in FIG5 , the first atomization driving circuit 212 includes a first switch tube Q1 , a first resistor R1 and a first atomization core interface J1 ; the first atomization core interface J1 is used to plug in the first atomization core 214 ; The gate of the first switch tube Q1 is connected to the controller, the source of the first switch tube Q1 is respectively connected to the power supply and the first end of the first resistor R1, the drain of the first switch tube Q1 is connected to the first atomizer core interface J1; the second end of the first resistor R1 is connected to the gate of the first switch tube Q1.

The controller can then identify the number of puffs taken by the user when smoking the electronic cigarette, and compare the number of puffs. When the number of puffs is less than a preset threshold, the controller transmits a first control signal to the first switch tube Q1 of the first atomization drive circuit 212. The first switch tube Q1 then switches on the path between the power supply and the first atomization core 214 according to the first control signal, thereby driving the first atomization core 214 to work, so that the first atomization core 214 starts the atomization function, atomizes the tobacco oil near the first end of the oil storage component, and generates atomized gas for the user to inhale. When the number of puffs is greater than or equal to a preset number threshold, the controller transmits a second control signal to the second switch tube Q2 of the second atomization drive circuit 222, and then the second switch tube Q2 conducts the path between the power supply and the second atomization core 224 according to the second control signal, thereby driving the second atomization core 224 to work, so that the second atomization core 224 starts the atomization function, atomizes the tobacco oil near the first end of the oil storage component, and then generates atomized gas for the user to inhale, thereby avoiding the situation in the later stage of the use of the electronic cigarette that the tobacco oil content near the second end of the oil storage component decreases, affecting the content of the generated atomized gas, and can improve the consistency of the user's inhalation taste, and achieve a stable atomization content of the tobacco oil to generate aerosol.
