Description

Technical Field

[0001] The present application relates to the field of atomization equipment, and in particular to an electronic atomization equipment and a control method and device thereof. Background Art

[0002] The prior art discloses an electronic atomization device, which is generally composed of a heating element, a battery, a control circuit and other parts. Currently, many electronic atomization devices usually use constant power to atomize the atomization matrix.

[0003] However, the atomization matrix is ​​usually composed of propylene glycol (PG) polymer and glycerol (VG) polymer, wherein the propylene glycol polymer has a low boiling point (the boiling point of the propylene glycol polymer is about 188°), and the glycerol polymer has a high boiling point (the boiling point of the glycerol polymer is about 290°).

[0004] At present, in order to quickly obtain enough atomized volume for users to inhale, many electronic atomization devices adopt a control method of rapid heating and then cooling, so that the heating element can quickly heat up and obtain enough atomized atomized matrix. However, due to the different boiling points of various substances in the atomized matrix and the large amount of atomized matrix, if the atomized matrix is ​​atomized at high power (greater than or equal to the highest boiling point of each substance in the atomized matrix), the low boiling point part of the atomized matrix will reach the boiling point too quickly, while the high boiling point part will not reach the boiling point, resulting in oil explosion. After oil explosion, the high boiling point part of the atomized matrix will be mixed into the atomized atomized matrix in liquid form, thereby affecting the taste of the user's inhalation.

[0052] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] In one embodiment, an electronic atomization device is provided, such as Figure 1 As shown, the electronic atomization device includes:

[0054] The processing module 120 , the power module 110 and the heating element 130 .

[0055] The power module 110 is used to provide energy to the heating element 130 and the processing module 120 respectively, so that the processing module 120 and the heating element 130 can work normally.

[0056] As an embodiment, the power module 110 can be connected to the processing module 120 and the heating element 130 respectively, and the processing module 120 can send a control instruction to the power module 110 to control the output power of the power module 110 to the heating element 130. As another embodiment, the power module 110, the processing module 120 and the heating element 130 can be connected in sequence, and the processing module 120 can control the on-off between the processing module 120 and the heating element 130 by realizing its own on-off, so as to realize the control of the output power of the power module 120 to the heating element 130.

[0057] The processing module 120 is used to control the power module to provide energy to the heating element according to a first preset power within a first time, and to provide energy to the heating element according to a second preset power within a second time during the process of the electronic atomization device being puffed; wherein the first preset power is less than the minimum atomization power corresponding to the first part of the atomization matrix in the electronic atomization device, the second preset power is greater than or equal to the minimum atomization power corresponding to the first part of the atomization matrix in the electronic atomization device, and the sum of the first time and the second time is less than or equal to the total time of a single puff of the electronic atomization device.

[0058] Specifically, in this embodiment, the electronic atomization device stores an atomization matrix, which can be stored in a cigarette cartridge (storage bin) during specific implementation. The atomization matrix includes at least a first part and a second part, and the boiling point of the first part is higher than the boiling point of the second part. For example, the first part can be a glycerol (VG, Vegetable Glycerin) polymer, and the second part can be a propylene glycol (PG, Propylene Glycol) polymer. In specific implementation, the composition of the atomization matrix can be selected according to actual conditions and is not limited here.

[0059] For a better understanding of this application, please refer to Figure 2 ,by Figure 2Taking the heating body 130 as an example, the heating body 130 has a ceramic substrate 131 and a porous heating film 132. The substrate 131 includes at least one through hole 1311. The ceramic substrate 131 includes a relative atomization surface and a liquid absorption surface. The porous heating film 132 is arranged on the atomization surface of the heating body 130. One end of the through hole 1311 is connected to the liquid absorption surface, and the other end is connected to the atomization surface. Among them, the material of the porous heating film 132 can be a heating material such as nickel-chromium alloy, stainless steel alloy, aluminum alloy, etc.; the structure of the porous heating film 132 can be any shape such as S-type, W-type (there is a regional temperature gradient difference); in one embodiment, the slurry of the porous heating film 132 is formed by printing on the ceramic substrate blank and then sintering together. The through hole 1311 is used to connect the storage bin storing the atomized matrix and the suction nozzle, so that the atomized matrix in the storage bin can enter the heating element 130. The heating element 130 will atomize the atomized matrix in contact with the heating element 130 during operation, and the user can inhale the atomized atomized matrix through the suction nozzle. Figure 3 , Figure 3 The through hole 1311 is shown to generate a capillary effect, that is, when the heating element 130 is not working, due to the unsaturated oil content, the oil in the oil tank will be sucked into the through hole 1311 of the heating element 130 or even overflow under the action of capillary action, increasing the oil film thickness of the heating element 130. Figure 3 The lower surface in the middle is the liquid absorption surface of the ceramic substrate 131, and the upper surface is the atomization surface of the ceramic substrate 131. As another embodiment, the atomized matrix can also flow directly from the storage bin to the atomization surface of the heating element 130. Figure 2 The heating element 130 is only used as an example, and in a specific implementation, the heating element may also be other structures.

[0060] Since the atomized matrix in the storage bin is a mixture of the first part and the second part, after flowing into the atomizing surface of the heating element 130, the atomized matrix on the atomizing surface of the heating element 130 also includes the second part with a low boiling point and the first part with a high boiling point. During the heating process of the heating element 130, if the heating element 130 is heated too quickly, the second part quickly reaches the boiling point and expands, and then ruptures after expanding to a certain extent, thereby causing the first part wrapped around the second part to explode, resulting in liquid explosion.

[0061] In order to solve the problem of explosive liquid, after detecting that the electronic atomization device is being sucked, the electronic atomization device enters a sucked state. Specifically, the processing module 120 detects the suction action through the airflow sensor in the electronic atomization device. As an embodiment, after detecting the suction action, the airflow sensor sends information that the electronic atomization device is being sucked to the processing module 120, or the processing module 120 obtains the signal detected by the airflow sensor, and detects whether the electronic atomization device is being sucked according to the signal detected by the airflow sensor. As another embodiment, the user can also trigger the heating start signal / suction start signal through the physical / virtual button in the electronic atomization device, so that the processing module 120 detects that the electronic atomization device is being sucked.

[0062] During the process of the electronic atomization device being inhaled, the control power module 110 provides energy to the heating element 130 according to the first preset power in the first time, and provides energy to the heating element 130 according to the second preset power in the second time, see Figure 4 When atomization starts, the processing module 120 controls the power module 110 to provide energy to the heating element 130 through a first preset power (P1) that is less than the minimum atomization power corresponding to the first part. At this time, the power output by the power module 110 is relatively small, and the temperature of the heating element 130 rises slowly, so that the second part with a low boiling point can be atomized, and at the same time, a small part of the first part with a high boiling point can also be atomized (that is, the amount of atomization of the second part is greater than the amount of atomization of the first part), thereby consuming the oil film on the surface of the ceramic and the heating film, reducing the thickness of the oil film. On the one hand, the second part in the atomization matrix is ​​reduced, and on the other hand, the reduced thickness of the oil film can make the second part rupture as soon as possible after expansion, or be directly atomized, thereby avoiding the explosion phenomenon. After the first time (T1), the processing module 120 controls the power module 110 to use a second preset power (P2) greater than or equal to the minimum atomization power corresponding to the first part to provide energy to the heating element 130. At this time, the temperature of the heating element 130 continues to rise, and the atomization matrix can be quickly atomized, increasing the atomization amount. The second preset power P2 is used to work for the second time (T2) until the end of this puff or close to the end of this puff. In other words, the sum of the first time and the second time is less than or equal to the total time that the electronic atomization device is puffed once. Exemplarily, assuming that the average puffing time is 5 seconds for one puff, the sum of the first time and the second time is less than or equal to 5 seconds. It should be noted that the size relationship between the first time and the second time can be set according to the actual situation. For example, when a large amount of atomization is required, the second time can be set longer. When a sweet taste is required (because the sweetness mainly comes from the second part of the atomization matrix), the first time can be set longer.

[0063] The electronic atomization device includes: a processing module, a power module and a heating element; the power module is used to provide energy to the heating element and the processing module respectively; the processing module is used to control the power module to provide energy to the heating element according to the first preset power in the first time and to provide energy to the heating element according to the second preset power in the second time during the process of the electronic atomization device being sucked; wherein the atomization matrix in the electronic atomization device includes at least a first part and a second part, the boiling point of the first part is higher than the boiling point of the second part, the first preset power is less than the minimum atomization power corresponding to the first part, the second preset power is greater than or equal to the minimum atomization power corresponding to the first part, and the sum of the first time and the second time is less than or equal to the total time of the electronic atomization device being sucked once. In the above manner, in the process of the electronic atomization device being sucked, the atomization matrix is ​​more at the beginning, and the atomization matrix is ​​first heated by the lower first preset power, so that the atomization matrix near the heating element is reduced, and then the second preset power is used to continue to heat up, thereby avoiding the explosion phenomenon caused by the rapid heating and boiling of the second part with a low boiling point in the atomization matrix, thereby improving the user's taste during the suction process.

[0064] As an embodiment, the processing module 120 is further configured to:

[0065] During the process of the electronic atomization device being inhaled, the power module 110 is controlled to provide energy to the heating element 130 according to a first preset power within a first time period, to provide energy to the heating element 130 according to a second preset power within a second time period, and to provide energy to the heating element 130 according to a third preset power within a third time period;

[0066] The third preset power is less than the second preset power, and the sum of the first time, the second time and the third time is equal to the total time of a single inhalation of the electronic atomization device.

[0067] Specifically, the difference between this embodiment and the previous embodiment is that: the previous embodiment divides the time of a single puff into two time periods, while the present application divides the time of a single puff into three time periods. Figure 5, the processing module 120 controls the power module 110 to provide energy to the heating element 130 through a first preset power (P1) that is less than the minimum atomization power corresponding to the first part. At this time, the power output by the power module 110 is relatively small, and the temperature of the heating element 130 rises slowly, so that the second part with a low boiling point can be atomized, and at the same time, a small part of the first part with a high boiling point can also be atomized (that is, the amount of atomization of the second part is greater than the amount of atomization of the first part), thereby consuming the oil film on the surface of the ceramic and the heating film, reducing the thickness of the oil film. On the one hand, the second part in the atomization matrix is ​​reduced, and on the other hand, the reduced thickness of the oil film can make the second part rupture as soon as possible after expansion, or be directly atomized, thereby avoiding the explosion phenomenon. After the first time (T1), the processing module 120 controls the power module 110 to provide energy to the heating element 130 using a second preset power (P2) greater than or equal to the minimum atomization power corresponding to the first part. At this time, the temperature of the heating element 130 continues to rise, and the atomization matrix can be quickly atomized to increase the atomization amount; after the second time, the processing module 120 controls the power module 110 to provide energy to the heating element 130 using a third preset power (P3) for a third time. The third preset power is less than the second preset power. The sum of the first time, the second time and the third time is equal to the total time of a single puff of the electronic atomization device, that is, the higher second preset power is used and then the lower third preset power is used to provide energy. This is mainly because within the third time, the current puff is approaching the end. At this time, the user's puffing strength is reduced and the atomization amount needs to be less, so the power can be reduced to reduce the energy provided to the heating element 130. The relationship between the first preset power and the third preset power can be set according to actual conditions, for example, the first preset power is less than or equal to the third preset power; or the first preset power is greater than or equal to the third preset power.

[0068] Furthermore, the third preset power is less than or equal to the average of the first preset power and the second preset power. That is, the minimum first preset power is used for slow heating in the first time to reduce the atomized matrix near the heating element 130, and then the highest second preset power is used for rapid heating in the second time to increase the atomization amount, and finally the third preset power is used for stabilizing the atomization amount in the third time.

[0069] Among them, the first time, the second time and the third time can also be set according to actual needs, for example, the first time, the second time and the third time are equal; or the first time and the second time are both less than one-third of the total time, and the third time is greater than one-third of the total time, and the total time is the total time of one puff. At this time, correspondingly, during one puff process, the first time, the second time and the third time are configured as the sum of the durations covering the total time of the puff process.

[0070] As another embodiment, during a puffing process, the first time, the second time, and the third time are configured to be periodically distributed, and the sum of the durations of multiple cycles covers the total time of the puffing process. Specifically, within a cycle, the first time, the second time, and the third time are equal in duration; or within a cycle, the first time and the second time are both less than one third of the total time, and the third time is greater than one third of the total time.

[0071] In some embodiments, the first preset power is greater than or equal to the minimum atomization power corresponding to the second part, and less than the minimum atomization power corresponding to the first part. Thus, the second part is atomized as quickly as possible in the first time, thereby avoiding the explosion phenomenon. Of course, the first preset power can also be slightly less than the minimum atomization power corresponding to the second part, which can also basically avoid the explosion phenomenon.

[0072] It can be understood that the first preset power is greater than or equal to the minimum atomization power corresponding to the second part, and is less than the minimum atomization power corresponding to the first part. The overall atomization amount is kept on par with the atomization amount in the prior art to meet the user's puffing needs. Exemplarily, assuming that the constant power output is P=7.5W and the puffing time is T=3S, in order to ensure the same energy supply, the variable power parameter can be set to P1*T1+P2*T2+P3*T3=P*T; in the first stage of puffing, there is a lot of oil on the surface of the heating element 130 and the connected storage bin component, and P1=6.5W is set to prevent the "oil frying" phenomenon caused by the rapid heating rate of the heating element 130, which causes the atomization matrix to be violently atomized and causes the atomization matrix to be violently atomized. In the second stage of suction, the amount of oil in the heating element 130 and the connected storage bin components is reduced and the temperature has risen. P2 can be set to 8.5W to heat the atomizing matrix to fully atomize the first part of the high boiling point in the atomizing matrix. In the third stage of suction, the heating element 130 and the atomizing matrix on the heating element 130 have reached the set maximum atomizing temperature and the amount of the atomizing matrix on the heating element 130 has further decreased. P3 ≤ 7.5W can be set to increase the overall smoke volume at a constant atomizing temperature. The suction ends and enters the next cycle to re-execute the above process.

[0073] In some embodiments, the electronic atomization device further comprises:

[0074] A detection module (not shown), used to detect the suction signal of the electronic atomization device;

[0075] The processing module 120 is further used to determine the first time and the second time according to the suction signal, and control the power supply module to provide energy to the heating element according to the first preset power during the first time, and to provide energy to the heating element according to the second preset power during the second time.

[0076] Specifically, the difference between this embodiment and the above embodiment is that the first time and the second time in this embodiment are not fixedly set. In this embodiment, a detection module is also provided in the electronic atomization device, and the detection module can detect the suction signal of the electronic atomization device. The processing module 120 can determine the suction intensity according to the detected suction signal. The greater the suction intensity, the greater the suction signal, so that the processing module 120 can determine the first time and the second time. Exemplarily, if the suction value corresponding to the suction signal is less than or equal to the preset suction intensity, the first time is the preset time, for example, 1 second. If the suction value corresponding to the suction signal is greater than the preset suction intensity within 1 second, the first time is reduced to 0.8 seconds. It can be understood that if the duration of the suction at this time is greater than 0.8 seconds and less than 1 second, the second time is immediately entered. As another embodiment, the first time and the second time can also be set according to the suction signal value, and the first time and the second time can be dynamically adjusted according to the suction signal. Then, within the first time, the processing module 120 controls the power module to provide energy to the heating element according to the first preset power, and within the second time, the processing module 120 provides energy to the heating element according to the second preset power.

[0077] In some embodiments, the electronic atomization device further comprises:

[0078] Processing module 120, power module 110 and heating element 130;

[0079] The power module 110 is used to provide energy to the heating element 130 and the processing module 120 respectively;

[0080] The processing module 120 is used to control the power module 110 to provide energy to the heating element 130 according to the first preset power in the first time, to provide energy to the heating element 130 according to the second preset power in the second time, and to provide energy to the heating element 130 according to the third preset power in the third time period during the process of the electronic atomization device being inhaled;

[0081] The third preset power is smaller than the second preset power, and the first preset power is smaller than the second preset power.

[0082] In order to solve the problem of explosive liquid, after detecting that the electronic atomization device is being sucked, the electronic atomization device enters a sucked state. Specifically, the processing module 120 detects the suction action through the airflow sensor in the electronic atomization device. As an embodiment, after detecting the suction action, the airflow sensor sends information that the electronic atomization device is being sucked to the processing module 120, or the processing module 120 obtains the signal detected by the airflow sensor, and detects whether the electronic atomization device is being sucked according to the signal detected by the airflow sensor. As another embodiment, the user can also trigger the heating start signal / suction start signal through the physical / virtual button in the electronic atomization device, so that the processing module 120 detects that the electronic atomization device is being sucked.
