Electronic atomization device and control method and device thereof

[0001] Related applications

[0002] This application claims priority to Chinese patent application number 2023108982515, filed on July 20, 2023, entitled “Electronic atomization device and its control method and device,” the entire text of which is hereby incorporated by reference. Technical Field

[0003] 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

[0004] Conventional technology 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.

[0005] However, the aerosol 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°).

[0006] 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 with 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 the oil explosion occurs, 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.

[0060] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0061] In one embodiment, an electronic atomization device is provided, as shown in FIG1 , the electronic atomization device includes:

[0062] The processing module 120 , the power module 110 and the heating element 130 .

[0063] 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 operate normally.

[0064] As an embodiment, the power module 110 can be connected to the processing module 120 and the heating element 130 respectively. In this case, 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. In this case, the processing module 120 can control the connection and disconnection between the processing module 120 and the heating element 130 by turning itself on and off, thereby controlling the output power of the power module 120 to the heating element 130.

[0065] The processing module 120 is used to control the power supply module to provide energy to the heating element according to the first preset power within the first time and to provide energy to the heating element according to the second preset power within the 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.

[0066] Specifically, the electronic atomization device in this embodiment stores an atomization matrix. In a specific implementation, the atomization matrix can be stored in a cigarette cartridge (storage bin). The atomization matrix 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. 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 a specific implementation, the composition of the atomization matrix can be selected according to actual conditions and is not limited here.

[0067] In order to better understand the present application, please refer to Figure 2. Taking the heating body 130 described in Figure 2 as an example, the heating body 130 has a ceramic substrate 131 and a porous heating membrane 132. The substrate 131 includes at least one through hole 1311. The ceramic substrate 131 includes a relative atomizing surface and a liquid absorption surface. The porous heating membrane 132 is arranged on the atomizing 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 atomizing surface. The material of the porous heating membrane 132 can be a heating material such as nickel-chromium alloy, stainless steel alloy, aluminum alloy, etc. The structure of the porous heating membrane 132 can be any shape such as S-type, W-type (there are regional temperature gradient differences); in one embodiment, the porous heating membrane 132 slurry is printed on the ceramic substrate blank and then sintered together to form. The through hole 1311 is used to connect the storage bin for storing the atomized matrix and the suction nozzle, so that the atomized matrix in the storage bin can enter the heating element 130. During the operation of the heating element 130, the atomized matrix of the heating element 130 in contact will be atomized, and the user can inhale the atomized atomized matrix through the suction nozzle. Specifically, referring to Figure 3, Figure 3 shows a state in which a through hole 1311 produces a capillary action, that is, when the heating element 130 is not working, due to the presence of oil unsaturation, under the action of capillary action, the tobacco oil in the oil bin will be sucked into the through hole 1311 of the heating element 130 or even overflow, increasing the oil film thickness of the heating element 130. The lower surface in Figure 3 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. The heating element 130 described in Figure 2 is only an example, and the heating element can also have other structures in the specific implementation.

[0068] Because the atomized matrix in the storage chamber is a mixture of the first and second parts, 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 lower boiling point and the first part with a higher boiling point. During the heating process of the heating element 130, if the heating element 130 heats up too quickly, the second part will quickly reach its boiling point and expand. After expanding to a certain extent, it will rupture, causing the first part that encloses the second part to explode, resulting in a liquid explosion.

[0069] In order to solve the problem of explosive liquid, after detecting that the electronic atomization device is being sucked, the electronic atomization device enters the sucked state. Specifically, the processing module 120 detects the sucking action through the airflow sensor in the electronic atomization device. As an embodiment, after detecting the sucking 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 detection signal from 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.

[0070] During the process of the electronic atomization device being sucked, the control power module 110 provides energy to the heating element 130 according to the first preset power within the first time, and provides energy to the heating element 130 according to the second preset power within the second time. Referring to Figure 4, within one cycle, the second time is after the first time, when atomization begins, the processing module 120 controls the power module 110 to provide energy to the heating element 130 through the first preset power (P1) which is less than the minimum atomization power corresponding to the first part. At this time, the power output by the power module 110 is 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, it reduces the second part in the atomization matrix, 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 supply 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. For example, assuming that the average puff 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 actual conditions. 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.

[0071] The above-mentioned 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 within the first time and to provide energy to the heating element according to the second preset power within the second time during the process of the electronic atomization device being puffed; 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 that the electronic atomization device is puffed once. Through the above method, in the process of the electronic atomization device being puffed, the atomization matrix is ​​initially more, 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 heating, 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 puffing process.

[0072] As an embodiment, the processing module 120 is further configured to:

[0073] During the process of the electronic atomization device being inhaled, the control power supply module 110 provides energy to the heating element 130 according to the first preset power in the first time period, provides energy to the heating element 130 according to the second preset power in the second time period, and provides energy to the heating element 130 according to the third preset power in the third time period;

[0074] 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 puff of the electronic atomization device.

[0075] Specifically, the difference between this embodiment and the previous embodiment is that: in the previous embodiment, the time of a single puff is divided into two time periods, while in this application, the time of a single puff is divided into three time periods. Referring to Figure 5 at the same time, within one cycle, the second time is after the first time, and the third time is after the second time. 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 of the power module 110 is 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 oil film thickness can cause the second part to 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, which can quickly atomize the atomization matrix and increase the atomization amount. After the second time, the processing module 120 controls the power module 110 to use a third preset power (P3) to provide energy to the heating element 130 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 nearing the end. At this time, the user's puffing force is reduced and the atomization amount required is less. Therefore, 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.

[0076] 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 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 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.

[0077] 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. In this case, correspondingly, during one puff process, the first time, the second time and the third time are configured so that the sum of the durations covers the total time of the puff process.

[0078] As another embodiment, during a single puff, the first, second, and third times are periodically distributed, and the sum of the durations of the multiple cycles covers the total duration of the puff. Specifically, within a cycle, the first, second, and third times are equal in duration; or within a cycle, the first and second times are each less than one-third of the total time, and the third time is greater than one-third of the total time.

[0079] In some embodiments, the first preset power is greater than or equal to the minimum atomization power corresponding to the second portion, and less than the minimum atomization power corresponding to the first portion. This allows the second portion to be atomized as quickly as possible, thereby avoiding liquid explosion. Of course, the first preset power can also be slightly less than the minimum atomization power corresponding to the second portion, which can also basically avoid liquid explosion.

[0080] 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. This allows the overall atomization amount to remain on par with the atomization amount in traditional technology, satisfying the user's puffing needs. For example, 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 section of puffing, the amount of oil on the surface of the heating element 130 and the connected storage bin components is relatively large, and setting P1=6.5W can prevent the "oil frying" phenomenon caused by the intense atomization of the atomization matrix due to the excessively fast heating rate of the heating element 130, and make the second part of the atomization matrix with a low boiling point During the second puff, the amount of oil in the heating element 130 and the connected storage compartment has decreased and the temperature has risen. P2 can be set to 8.5W to heat the atomizing matrix and fully atomize the first high-boiling-point portion of the atomizing matrix. During the third puff, the heating element 130 and the atomizing matrix on the heating element 130 have reached the set maximum atomization temperature and the amount of atomizing matrix on the heating element 130 has further decreased. P3 can be set to ≤ 7.5W to maintain a constant atomization temperature and increase the overall vapor volume. The puff ends and the next cycle begins, repeating the above process.

[0081] In some embodiments, the electronic atomization device further comprises:

[0082] A detection module (not shown) is used to detect the puff signal of the electronic atomization device;

[0083] The processing module 120 is further configured to determine a first time and a 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 within the first time, and to provide energy to the heating element according to the second preset power within the second time.

[0084] Specifically, the difference between this embodiment and the above embodiment is that the first time and the second time in this embodiment are not fixed. In this embodiment, the electronic atomization device is further provided with a detection module that can detect the puff signal of the electronic atomization device. The processing module 120 can determine the puff intensity based on the detected puff signal. The greater the puff intensity, the greater the puff signal, so that the processing module 120 can determine the first time and the second time. For example, if the puff value corresponding to the puff signal is less than or equal to the preset puff intensity, the first time is the preset time, for example, 1 second. If the puff value corresponding to the puff signal is greater than the preset puff intensity within 1 second, the first time is reduced to 0.8 seconds. It can be understood that if the puff duration 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 puff signal value, and the first time and the second time can be dynamically adjusted according to the puff signal. Then, during 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 during the second time, the processing module 120 provides energy to the heating element according to the second preset power.

[0085] In some embodiments, the electronic atomization device further comprises:

[0086] Processing module 120, power module 110 and heating element 130;

[0087] The power module 110 is used to provide energy to the heating element 130 and the processing module 120 respectively;

[0088] The processing module 120 is configured to control the power supply module 110 to supply energy to the heating element 130 according to a first preset power within a first time period, to supply energy to the heating element 130 according to a second preset power within a second time period, and to supply energy to the heating element 130 according to a third preset power within a third time period during the process of the electronic atomization device being puffed;

[0089] The third preset power is smaller than the second preset power, and the first preset power is smaller than the second preset power.

[0090] In order to solve the problem of explosive liquid, after detecting that the electronic atomization device is being sucked, the electronic atomization device enters the sucked state. Specifically, the processing module 120 detects the sucking action through the airflow sensor in the electronic atomization device.
