Description

Electronic cigarette control method for better reducing the taste of smoke oil and electronic cigarette

Technical field

The present invention relates to the technical field of electronic cigarettes atomized with liquid cigarette oil, and in particular to a method for controlling electronic cigarettes and electronic cigarettes.

Background technique

The traditional way of smoking is to use an open flame to ignite the tobacco, and the tobacco is burned to produce smoke for the smoker to smoke. The smoke produced by the burning of tobacco usually contains thousands of harmful substances. Therefore, traditional smoking methods not only cause serious respiratory diseases to smokers, but also easily bring harm to second-hand smoke. In order to solve the traditional smoking method, many types of electronic cigarettes that use liquid e-liquid atomized have emerged.

At present, there are three common control methods for electronic cigarettes on the market, one is fixed output voltage, one is full voltage output (directly output battery voltage), and the other is temperature control output with constant heating wire temperature.

1. The control method of the fixed voltage output is from the beginning to the end of smoking, the fixed output voltage is set to heat the heating wire, even if the voltage is adjustable, the set voltage value is adjusted, and it is fixed according to the newly set voltage when smoking Output. For example, some electronic cigarette control modules output a fixed 3.4V, 3.5V or 3.6V drive voltage, and the output is fixed during smoking; the control method of fixed voltage output is shown in Figure 1: In the figure, Vbat is the battery voltage and Vout is the setting The output voltage is generally fixed at 3.4V, 3.5V or 3.6V. The curve in the figure is the output voltage curve, puff1 is the first puff, puff2 is the second puff, puff3 is the third puff and so on.

2. The control method of full voltage output means that the control circuit does not control the output voltage when smoking, but directly outputs the voltage of the battery. The output voltage is the same as the battery voltage or has a small voltage drop (the voltage drop caused by the internal resistance of the control circuit) ; The control method of full voltage output is as shown in Figure 2: In the figure, Vbat is the battery voltage, Vout is the set voltage, and the voltage of Vout changes with the voltage of Vbat. The curve in the figure is the output drive voltage curve, puff1 is the first puff, puff2 is the second puff, puff3 is the third puff and so on.

3. The temperature control method of constant heating wire temperature means that the temperature of the heating wire maintains a fixed temperature when smoking; if there is an adjustment temperature, the output will be maintained at the new set temperature after adjustment. The ideal control model of constant heating wire temperature is shown in Figure 3: Tset in the figure is the set control temperature, the curve in the figure is the ideal temperature control output curve, puff1 is the first puff of smoke, puff2 is the second puff, puff3 is the third puff and so on.

The above-mentioned first and second electronic cigarette output control methods have a common defect, that is, the second half of a puff, or a few consecutive puffs, and the subsequent puffs of smoke have poor reduction of the taste of the e-liquid The reason is that the oil-conducting cotton or ceramic has a certain speed of oil supply, and the larger smoke needs to consume the e-liquid at a certain speed. Continuous smoking will cause the consumption of the e-liquid to increase (because the temperature of the oil-conducting cotton or ceramic will Higher and higher), resulting in the fuel supply speed can not keep up, so the later smoke temperature is too high, the smoke oil taste worse. None of these driving methods can well restore the true taste of e-liquid.

For the third constant-temperature temperature control driving method, there is also a problem that the amount of smoke is low at the temperature that restores the taste of the smoke, and if a large smoke taste is required, a higher temperature is required, so the fuel supply speed cannot keep up. On the other hand, the taste of the smoke is reduced, and the taste of the smoke cannot be restored well.

Therefore, how to provide an electronic cigarette that better restores the taste of the e-liquid has become an urgent problem for electronic cigarettes.

Note, instead of limiting the technical solution of the present application, the embodiments of the present invention and the technical features in the embodiments can be combined with each other if there is no conflict.

Example one

This embodiment provides an electronic cigarette control method for better restoring the taste of e-liquid. The electronic cigarette includes a battery assembly and an atomizing assembly connected to the battery assembly. The related structures and settings of the battery assembly and the atomizing assembly belong to The scope of the existing technology will not be repeated here.

Referring to FIG. 4, the control method includes the following processing steps:

S1, sensing a smoking signal, and receiving the smoking signal;

S2. When receiving each puff of smoking signal, according to the first preset high and low atomization parameter ratio, control the battery assembly to alternately heat the e-liquid of the atomization assembly.

The smoking signal in step S1 can be sensed by the airflow sensor in the electronic cigarette; when the electronic cigarette is activated, the sensor enters the working state to sense the smoking signal in real time. In addition, the smoking signal can also be a signal generated by the user's triggering of the smoking key switch. Therefore, the manner in which the signal is generated is not specifically limited herein.

In step S2, the battery components are controlled to alternately atomize and heat the e-liquid of the atomized components, the purpose of which is to ensure that the taste of e-liquid can be better restored under the condition of a large amount of smoke, without causing burnt smell or excessive temperature. The odor caused. The battery assembly can alternately atomize and heat the e-liquid of the atomization assembly because the atomization parameters are set in a high-low staggered manner.

In order to make the e-cigarette better restore the taste of the e-liquid while ensuring a larger amount of smoke, and will not produce burnt smell or peculiar smell caused by too high temperature, this control method will also adjust the first level according to the oil guide speed. The atomization parameter ratio is adjusted; that is, the first high-low atomization parameter ratio in the step S2 can be adjusted according to the oil guide speed, and the adjustment includes the first high-low atomization parameter ratio. The adjustment of the ratio between a period of time and its adjacent low fogging parameter for a period of time. According to the received smoking signal, the oil guiding speed can be obtained. When the oil guiding speed is high, the ratio of the high atomization parameter for a period of time to the adjacent low atomization parameter for a period of time can be increased appropriately; When the speed is small, the ratio of the high atomization parameter for a period of time and the adjacent low atomization parameter for a period of time can be appropriately reduced.

In this embodiment, the atomization parameter includes a voltage parameter. In this case, the first high-low atomization parameter includes a plurality of interval-set high-voltage heating time periods and a plurality of interval-set low-voltage heating time periods. The high-voltage heating time period and the plurality of low-voltage heating time periods are alternately arranged at intervals, and the first high-low atomization parameter ratio includes one high-voltage heating time period and one adjacent low-voltage heating time period. The ratio of the heating time period. At this time, the adjustment of the first high-low atomization parameter ratio includes: adjusting the ratio of one high-voltage heating time period to one adjacent low-voltage heating time period according to the oil guiding speed. The high voltage is a set voltage for full atomization, and the low voltage is a set voltage for light atomization waiting for sufficient fuel supply. The interleaved setting of the high voltage heating time period and the short interval of the low voltage heating time can be seen in FIG. 5, which is an interleaved setting in the form of high voltage-low voltage-high voltage-low voltage; further, the high voltage heating The interval staggered setting of the time period and the short heating time of the low voltage can also be that the preset time period values between the high voltages are sequentially set at intervals, and the preset time period values between the high voltages are sequentially set at intervals, such as Set the high voltage time period in Figure 5 as: t1 is 0.6 seconds, t3 is 0.5 seconds, t5 is 0.6 seconds, t7 is 0.5 seconds, etc., and the low voltage time period is set as: t2 is 0.4 seconds, t4 is 0.45 seconds, t6 is 0.4 seconds, t8 is 0.45 seconds, and so on.

Refer to Figure 5. Figure 5 is the voltage driving diagram of the atomization component when the atomization parameter is the voltage parameter. Vbat in the figure is the battery voltage. After long-term use, the internal materials of the battery age, and the output voltage will show a downward trend; The curve is the controlled output voltage, Vs1 is the set fixed voltage 1, which is high voltage; Vs2 is the set fixed voltage 2, which is low voltage; the set value of Vs1 and Vs2 can be based on different heating wires and conductors. Adjust the oil speed and different e-liquid. In this embodiment, Vs1 is set to 3.6V, and Vs2 is set to 3.0V; t1～tn are preset time values, among which t1, t3, t5, etc. are high Voltage heating time periods, t2, t4, t6, etc. are low voltage heating time periods; the ratio of high and low atomization parameters may be the ratio of t1 to t2. Each time value can be adjusted according to taste, for example, t1 is 0.6 seconds, t2 is 0.4 seconds, t3 is 0.55 seconds, t4 is 0.5 seconds, t5 is 0.45 seconds, t6 is 0.6 seconds, and so on. puff1 is the first puff, puff2 is the second puff, and puff3 is the third puff. In this embodiment, the value of Vs1 is set to the voltage value during full atomization, and the value of Vs2 is set to the voltage value during light atomization waiting for full fuel supply. The advantage of this is that the atomized smoke will not Overheating, there will be no burnt smell, which ensures the taste of the smoke oil and produces large smoke.

Referring to Fig. 5, in order to prevent the electronic cigarette from being heated for a long time at the preset ratio of the first high and low physicochemical parameters, causing the loss of power; the duration of the e-liquid of the atomizing assembly being atomized and heated at the first high and low atomization parameter ratio It is equal to the duration of receiving each puff of smoking signal; and when the gap between the first puff and the next puff is smoked, the atomization component of the electronic cigarette will stop heating. At this time, the step 2 is specifically implemented as follows: when receiving each puff of smoking signal, according to the preset first high and low atomization parameter ratio, control the battery assembly to alternately heat the e-liquid of the atomization assembly. The duration of the atomization heating is equal to the duration of each received smoking signal; when the smoking signal is terminated, the heating of the atomization assembly is stopped.

Refer to Figure 6, in order to prevent the user from smoking for a long time and cause the temperature of the e-liquid to decrease, the e-cigarette cannot quickly produce sufficient smoke concentration during the next smoking. It is necessary to heat the e-cigarette when the smoking signal is stopped, such as setting A certain voltage heats the atomization component to maintain the temperature of the electronic cigarette. At this time, the specific implementation of step 2 is: when receiving each puff of smoking signal, according to the preset first high and low atomization parameter ratio, control the battery assembly to alternately heat the cigarette oil of the atomization assembly, so The duration of the atomization heating is equal to the duration of each received smoking signal; when the smoking signal is terminated, within a preset time period, the atomization component is heated and insulated according to the set third voltage. The third voltage is less than the low voltage, that is, the Vs3 is less than the Vs2; the Vs3 can be set to 2.6V.

In this embodiment, the step 2 can also be: when receiving each puff of smoking signal, according to the preset first high and low atomization parameter ratio, control the battery assembly to alternately heat the e-liquid of the atomization assembly to atomize and heat. The duration of the atomization heating is equal to the duration of each received smoking signal; when the smoking signal is terminated, within a preset time period, the atomization component is performed in accordance with the preset second high and low atomization parameter ratio Heat preservation. The settings of the second high-low atomization parameter and the first high-low atomization parameter are the same, except that the values of the selected high voltage and low voltage are different, which will not be repeated here.

When the smoking signal cessation time exceeds the preset time period, the heat preservation and heating of the atomization component is stopped to avoid the loss of electricity of the electronic cigarette. Among them, the duration of the preset time period is generally recommended to be 2 to 5 minutes, and users can also set it according to their own needs.

After long-term use, the internal materials of the battery will age, and its output voltage will show a downward trend. In order to ensure that the e-cigarette can better restore the taste of the e-liquid in the case of a large amount of smoke, and will not produce a burnt smell or excessive temperature At this time, the adjustment of the first high-low physicochemical parameter ratio also includes: when the battery voltage is lower than the high voltage in the first high-low atomization parameter, automatically amplify the high-low voltage time ratio, and heat the high voltage The value of the time period becomes longer, and the value of the low voltage heating time period becomes shorter. Specifically, when the battery voltage is lower than the high voltage in the first high and low atomization parameter, the ratio of the high and low voltage in the first high and low atomization parameter to the adjacent low voltage can be adjusted to 1.5:1 to 3. :1; For example, adjust the time periods in Figure 5 to: t1 is 0.8 seconds, t2 is 0.3 seconds, t3 is 0.9 seconds, t4 is 0.45 seconds, t5 is 0.85 seconds, t6 is 0.4 seconds, and so on.

In this embodiment, the atomization parameter also includes a temperature parameter. In this case, the high and low atomization parameters include a plurality of interval-set high-temperature heating time periods and a plurality of interval-set low-temperature heating time periods. The temperature heating time period and the plurality of low temperature heating time periods are alternately arranged at intervals, and the ratio of the high and low atomization parameters includes one of the high temperature heating time period and the adjacent one of the low temperature heating time period Ratio. At this time, adjusting the ratio of the high and low atomization parameters according to the oil guiding speed includes: adjusting the ratio of the high temperature heating time period to the adjacent low temperature heating time period according to the oil guiding speed. The high temperature is a set temperature for full atomization, and the low temperature is a set temperature for light atomization waiting for sufficient oil supply.

Refer to Figure 7. Figure 7 is the temperature driving diagram of the atomization component when the atomization parameter is the temperature parameter. The curve in the figure is the ideal heating wire temperature for control. Ts1 is the set control temperature 1, which is the high temperature; Ts2 is The set control temperature 2 is the low temperature. In this embodiment, Ts1 is set to 240°C and Ts2 is set to 180°C; t1～tn are preset time values, among which t1, t3, t5, etc. are High-temperature heating time periods, t2, t4, t6, etc. are low-temperature heating time periods; the high-low atomization parameter ratio may be the ratio of t1 to t2. Each time value can be adjusted according to taste, such as t1 is 0.6 seconds, t2 is 0.4 seconds, t3 is 0.5 seconds, t4 is 0.5 seconds, t5 is 0.4 seconds, t6 is 0.6 seconds, etc. puff1 is the first puff, puff2 is the second puff, and puff3 is the third puff. In this embodiment, the value of Ts1 is set to the temperature value during full atomization, and the value of Ts2 is set to the temperature value during light atomization while waiting for full fuel supply. The advantage of this is to ensure fuel supply and truly reduce smoke. Oily taste, no burnt smell.

Referring to FIG. 7, in order to prevent the electronic cigarette from being heated for a long time at the preset ratio of the first high and low physicochemical parameters, causing the loss of power; the duration of the e-liquid of the atomizing assembly being atomized and heated at the ratio of the first high and low atomization parameters It is equal to the duration of receiving each puff of smoking signal; and when the gap between the first puff and the next puff is smoked, the atomization component of the electronic cigarette will stop heating. The specific implementation corresponding to the step 2 is: when receiving each puff of smoking signal, according to the preset first high and low atomization parameter ratio, the battery assembly is controlled to alternately heat the e-liquid of the atomization assembly. The duration of the heating is equal to the duration of each received smoking signal; when the smoking signal is terminated, the heating of the atomizing assembly is stopped.

Referring to Figure 8, in order to prevent the user from smoking for a long time, the temperature of the e-cigarette will be lowered. The next time the e-cigarette smokes, the e-cigarette cannot quickly produce sufficient smoke concentration. It is necessary to heat the e-cigarette when the smoking signal is stopped. The temperature of the electronic cigarette can be maintained. At this time, the step 2 is specifically implemented as follows: when receiving each puff of smoking signal, according to the preset first high and low atomization parameter ratio, control the battery assembly to alternately heat the e-liquid of the atomization assembly. The duration of the atomization heating is equal to the duration of each received smoking signal; when the smoking signal is terminated, the temperature of the atomization component is controlled to the third temperature within a preset time period to keep the e-liquid warm. The third temperature is less than the low temperature, that is, the Ts3 is less than the Ts2; the Ts3 can be set to 150°C.

In this embodiment, the step 2 can also be: when receiving each puff of smoking signal, according to the preset first high and low atomization parameter ratio, control the battery assembly to alternately heat the e-liquid of the atomization assembly to atomize and heat. The duration of the atomization heating is equal to the duration of each received smoking signal; when the smoking signal is terminated, within a preset time period, the atomization component is performed in accordance with the preset second high and low atomization parameter ratio Heat preservation. The settings of the second high-low atomization parameter and the first high-low atomization parameter are the same, except that there is a difference between the selected high temperature and low temperature values, which will not be repeated here.

In order to improve the experience comfort of different users, the ratio of high and low fogging parameters can also be adjusted according to the user's own preferences. That is, the control method further includes: S3. The user adjusts the previously preset first high-low atomization parameter ratio according to the taste of the smoke currently inhaled, and uses the adjusted high-low atomization parameter ratio as the latest preset first high-low Atomization parameter ratio and save. When the user feels that the smoke concentration is not enough, he can adjust the preset first high and low atomization parameter ratio through the adjustment button or switch set on the electronic cigarette; or the electronic cigarette will sense the smoke concentration in real time during use, and The detected smoke concentration is automatically adjusted to the preset first high and low atomization parameter ratio. For example, when the smoke concentration is insufficient, the first high and low atomization parameter ratio is controlled to increase. When the smoke concentration is detected, the control The ratio of the first high-low atomization parameter decreases.

After the preset first high and low atomization parameter ratio is adjusted, the next time you smoke, the atomization heating will be performed according to the adjusted first high and low atomization parameter ratio. That is, after adjusting the first high-low physical-chemical parameter ratio: after completing the last puff, control the atomization component to stop heating, and after receiving the next puff signal, control the atomization component to follow the updated and adjusted preset first high and low The atomization parameter ratio performs atomization heating on the atomization component.

During the user's use of the electronic cigarette, in order to let the user know the working mode of the electronic cigarette, a light-emitting unit can be provided on the electronic cigarette to remind the user. That is, the control method of this embodiment further includes: controlling the light-emitting unit to emit light when the e-liquid is atomized and heated. Wherein, the light-emitting unit includes a first indicator light and a second indicator light, which respectively correspond to the prompt for heating the e-liquid of the atomization assembly by voltage driving and the prompt for heating the e-liquid of the atomization assembly by temperature driving. Specifically, when the e-liquid of the atomization assembly is heated by the voltage driving mode, the first indicator light is controlled to emit green light; when the e-liquid of the atomization assembly is heated by the temperature driving mode, the first indicator is controlled. The second indicator light glows green.

The circuit implementation scheme of this embodiment will be described below in conjunction with FIG. 9 and FIG. 10.
