[0030] Example:

[0031] The embodiment of the present invention provides an electronic atomization system, including an atomization liquid having a microcapsule 30 and an electronic atomization device. The microcapsule 30 includes a capsule membrane and a flavor component wrapped in the capsule membrane, wherein the capsule membrane encloses an inner cavity, and the flavor component is located in the inner cavity, so that the microcapsule 30 releases the flavor component after being ruptured, and the flavor component is mixed in the aerosol generated by the electronic atomization device and inhaled, thereby changing the user's smoking taste; the electrosensitive material includes at least one of cyanate ester and polypropylene, for example, the electrosensitive material can be cyanate ester. The atomization liquid can also contain nicotine and other tobacco extracts, and the flavor component can contain nicotine, and can also contain other flavor materials, such as plant extracts.

[0032] See also Figure 1 , Figure 2 and Figure 3 The electronic atomization device includes an atomizer 10, and the atomizer 10 includes an oil cup 1, an atomization assembly 2, and an electric field generating device 3. The oil cup 1 is provided with a liquid storage chamber 11 for storing atomized liquid having microcapsules 30, and the microcapsules 30 have flavor components and capsule membranes at least partially made of electrosensitive materials; the atomization assembly 2 is connected to the liquid storage chamber 11, and is used to heat the atomized liquid and make the microcapsules 30 release the flavor components when heated; the electric field generating device 3 is fixed to the oil cup 1, and the electric field generating device 3 is used to generate an electric field in the oil cup 1 that acts on the electrosensitive material to drive the microcapsules 30 to flow toward or away from the atomization assembly 2, and / or, when the intensity of the electric field is greater than a preset threshold, the capsule membrane of the microcapsule 30 is ruptured to release the flavor components.

[0033] Because the microcapsules 30 will flow toward or away from the atomizer assembly 2 under the drive of the electric field generated by the electric field generating device 3, and the atomizer assembly 2 can heat the atomized liquid and make at least part of the microcapsules 30 release flavor components, taking nicotine as an example, when the microcapsules 30 flow around the atomizer assembly 2 under the action of the electric field, they can be heated and broken by the atomizer assembly 2 to release nicotine, so that the nicotine content in the atomized liquid increases, thereby increasing the nicotine content during the next puff; when the microcapsules 30 move away from the atomizer assembly 2 under the action of the electric field, the nicotine content in the atomized liquid decreases, so that the nicotine content during the next puff decreases;

[0034] Alternatively, when the intensity of the electric field is greater than a preset threshold, the capsule membrane of the microcapsule 30 ruptures so that the flavor components are released into the atomized liquid, thereby increasing the nicotine content in the atomized liquid. When there is no need to adjust the nicotine content, the electric field generating device 3 does not work. Of course, the electric field driving the microcapsule 40 to move relative to the atomizing component 2 and the rupture of the microcapsule 30 can be performed simultaneously or in different time periods. Therefore, the nicotine content in the atomized liquid can be controlled by controlling the directional movement of the microcapsule 30 and / or rupturing the microcapsule 30 through the electric field generating device 3, thereby meeting the requirement that the content of flavor components such as nicotine can be changed during the smoking process and preventing taste attenuation, thereby improving the smoking experience.

[0035] It should be noted that the microcapsules 30 are insoluble in the atomized liquid and the atomized liquid is not allowed to penetrate into the microcapsules 30; when the taste is too light or too strong during the inhalation process, the electric field generating device 3 can be activated to adjust the nicotine content in the atomized liquid, thereby adjusting the inhalation taste. A large number of microcapsules 30 are arranged in the liquid storage chamber 11. When the microcapsules 30 flow around the atomizing component 2, the microcapsules 30 are stacked, so that the atomizing component 2 heats the adjacent part of the microcapsules 30 for a period of time. The capsule membrane of the microcapsule 30 also includes an organic phase change material, such as paraffin and polyols, and the organic phase change material is used to rupture the microcapsules 30 when heated.

[0036] See also Figure 1 , Figure 2 and Figure 3 The oil cup 1 has a lower oil hole 102 connected to the liquid storage chamber 11, and the atomizer assembly 2 is connected to the liquid storage chamber 11 through the lower oil hole 102. The electric field generated by the electric field generating device 3 is used to drive the microcapsules 30 to move towards or away from the lower oil hole 102, so that the concentration of the microcapsules 30 around the lower oil hole 102 increases or decreases, and the microcapsules 30 release flavor components after being ruptured by heat, thereby meeting the demand for the content of flavor components to be variable during the smoking process and preventing taste attenuation, thereby improving the smoking experience.

[0037] The electric field generating device 3 includes a plurality of electrode groups arranged at intervals in the oil cup 1, wherein, among the plurality of electrode assemblies, there is at least one first electrode group 31 arranged on one side of the oil cup 1 near the lower oil hole 102, and at least one second electrode group 32 arranged at intervals from the first electrode group 31 and having a different polarity, and at least two electrode groups arranged at intervals and having different polarities form an electric field after being energized, thereby ensuring that the microcapsules 30 can move toward or away from the lower oil hole 102. Among them, at least one of the plurality of electrode groups is a positive electrode, at least one is a negative electrode, and at least one negative electrode and at least one positive electrode form an electric field when energized, specifically, one of the first electrode group 31 and the second electrode group 32 is a positive electrode, and the other is a negative electrode, and the other electrode groups except the first electrode group 31 and the second electrode group 32 in the plurality of electrode groups can be positive electrodes or negative electrodes.

[0038] In the embodiment of the present invention, the electric field generated by the electric field generating device 3 can be a uniform electric field or a non-uniform electric field. The microcapsule 30 and the solute in the atomized liquid will both trigger a polarization effect under the action of the electric field, and the polarization effect of the solute is smaller than the polarization effect of the microcapsule 30, so that the microcapsule 30 will be driven by the dielectrophoretic force (the microcapsule 30 driven by the dielectrophoretic force generates an internal electric field inside); wherein, for a uniform electric field, the microcapsule 30 will move in the opposite direction of the electric field under the drive of the dielectrophoretic force; for a non-uniform electric field, the microcapsule 30 will move in the direction of a greater electric field intensity under the drive of the dielectrophoretic force, thereby controlling the directional movement of the microcapsule 30.

[0039] In some embodiments, the electric field generated by the electric field generating device 3 includes a non-uniform electric field, and the capsule membrane of the microcapsule 30 ruptures to release the flavor component when the minimum, maximum or average electric field strength of the non-uniform electric field is greater than a preset threshold. The microcapsule 30 can move in a directional manner under the action of the non-uniform electric field.

[0040] In some specific embodiments, in the electric field generated by the electric field generating device 3, the electric field strength for driving the microcapsule 30 to move in a directional manner is smaller than the electric field strength for rupturing the capsule membrane, and moving the microcapsule 30 and rupturing the microcapsule 30 can be performed separately.

[0041] See also Figure 1In some embodiments, the atomizer 10 further includes a vent pipe 5 connected to the bottom and top of the oil cup 1 and located in the liquid storage chamber 11, the vent pipe 5 has an air flow channel 101 spaced apart from the liquid storage chamber 11, and the side wall of the air flow channel 101 is provided with a lower oil hole 102 connected to the liquid storage chamber 11, and the atomizer assembly 2 is arranged in the vent pipe 5, and the atomizer assembly 2 is at least partially located in the air flow channel 101 and covers the lower oil hole 102. The electric field generating device 3 includes a first electrode group 31 and a second electrode group 32 both fixed on opposite sides of the cavity wall of the oil cup 1, wherein the first electrode group 31 can be arranged on the peripheral side wall of the vent pipe 5, and the second electrode group 32 is arranged on the inner peripheral wall of the oil cup 1, and the lengths of the first electrode group 31 and the second electrode group 32 are both extended in the circumferential direction, that is, the first electrode group 31 and the second electrode group 32 are both annular, and this arrangement mode has a shorter path for the microcapsule 30 to move around the lower oil hole 102, which is conducive to improving the response speed of the microcapsule 30.

[0042] It should be noted that the vent pipe 5 and the oil cup 1 may be an integrated structure or a split structure, and this application does not make any specific limitation on this.

[0043] See also Figure 1 The electronic atomization device also includes a power supply device 20 connected to the atomizer 10. The power supply device 20 is provided with a control module 201 and an adjustment module. The control module 201 is electrically connected to the atomization assembly 2 and the adjustment module respectively. The adjustment module is electrically connected to the electric field generating device 3. The adjustment module includes a gear adjustment device and a positive and negative pole switching device. The gear adjustment device can adjust the intensity of the electric field generated by each electrode group when it is energized by adjusting the voltage and current. The positive and negative pole switching device can adjust the polarity of each electrode group.

[0044] For example:

[0045] The gear adjustment device controls the first electrode group 31 and the second electrode group 32 to be energized, and a uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized. When the positive and negative switching device controls the first electrode group 31 to be positive and the second electrode group 32 to be negative, the microcapsule 30 will move toward the direction of the first electrode group 31 under the drive of the dielectrophoretic force, that is, the microcapsule 30 moves toward the direction of the lower oil hole 102; when the positive and negative switching device controls the first electrode group 31 to be negative and the second electrode group 32 to be positive, the microcapsule 30 will move toward the direction of the second electrode group 32 under the drive of the dielectrophoretic force, that is, the microcapsule 30 moves away from the lower oil hole 102.

[0046] In a specific example, the gear adjustment device may be provided with five gear buttons, and by setting the electric field strength graded setting, the output power of the electronic atomization device is different under different conditions, thereby saving the power of the electronic atomization device. Among them, the five gear buttons correspond to gear I, gear II, gear III, gear IV, and gear V respectively. The gear adjustment device controls the intensity of the electric field generated when the first electrode group 31 and the second electrode group 32 are energized to be divided into three levels: high, medium, and low. For example:

[0047] When the gear button is touched to put the electronic atomization device in gear position I, the electric field strength generated by the first electrode group 31 is high and the electric field strength generated by the second electrode group 32 is low, so that a non-uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized, and the microcapsule 30 will move toward the direction of the first electrode group 31 driven by the dielectrophoretic force, that is, the microcapsule 30 moves toward the direction of the lower oil hole 102.

[0048] When the gear button is touched to put the electronic atomization device in gear II, the electric field strength generated by the first electrode group 31 is medium and the electric field strength generated by the second electrode group 32 is low, so that a non-uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized, and the microcapsule 30 will move toward the direction of the first electrode group 31 driven by the dielectrophoretic force, that is, the microcapsule 30 moves toward the direction of the lower oil hole 102.

[0049] When the gear button is pressed to put the electronic atomization device in gear III, the first electrode group 31 and the second electrode group 32 are not energized, the electric field strength generated by the first electrode group 31 and the second electrode group 32 is zero, and the microcapsule 30 does not move.

[0050] When the gear button is touched to put the electronic atomization device in gear IV, the electric field strength generated by the first electrode group 31 is low and the electric field strength generated by the second electrode group 32 is medium, so that a non-uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized, and the microcapsule 30 will move toward the direction of the second electrode group 32 driven by the dielectrophoretic force, that is, the microcapsule 30 moves in the direction away from the lower oil hole 102.

[0051] When the gear button is touched to put the electronic atomization device in gear position V, the electric field strength generated by the first electrode group 31 is low and the electric field strength generated by the second electrode group 32 is high, so that a non-uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized, and the microcapsule 30 will move toward the direction of the second electrode group 32 driven by the dielectrophoretic force, that is, the microcapsule 30 moves in the direction away from the lower oil hole 102.

[0052] See also Figure 2In some embodiments, the electric field generating device 3 includes a first electrode group 31 and a second electrode group 32 respectively fixed to the top and bottom of the oil cup 1. Two first electrode groups 31 are provided, and the two first electrode groups 31 are provided on opposite sides of the ventilation pipe 5; two second electrode groups 32 are provided, and the two first electrode groups 31 are provided on opposite sides of the ventilation pipe 5; this arrangement can control the directional movement of the microcapsules 30 in the liquid storage chamber 11 by partition, which is conducive to the switching of different flavors. It should be understood that the structure of the electronic atomization device, the gear adjustment device and the control method of the positive and negative switching device in this embodiment are the same as those in the previous embodiment, and will not be discussed here.

[0053] See also Figure 3 In some embodiments, the atomizer 10 further comprises a housing 4 having a housing cavity, the oil cup 1 is fixed in the housing cavity, an airflow channel 101 spaced from the liquid storage cavity 11 is formed in the oil cup 1, a lower oil hole 102 communicating with the liquid storage cavity 11 is provided on the side wall of the airflow channel 101, and the atomizer assembly 2 is at least partially located in the airflow channel 101 and covers the lower oil hole 102. Specifically, the airflow channel 101 is formed between the oil cup 1 and the inner peripheral wall of the housing 4, the lower oil hole 102 is located at the bottom of the oil cup 1, and the atomizer assembly 2 is assembled at the bottom of the oil cup 1; the electric field generating device 3 comprises a first electrode group 31, a second electrode group 32 and a third electrode group 33 all fixed to the oil cup 1, the first electrode group 31 and the second electrode group 32 form a uniform electric field after being energized, and the first electrode group 31, the second electrode group 32 and the third electrode group 33 form a non-uniform electric field after being energized. Among them, the first electrode group 31 is fixed to the top of the oil cup 1, the second electrode group 32 and the third electrode group 33 are fixed to the bottom of the oil cup 1, and the second electrode group 32 and the third electrode group 33 are distributed on both sides of the lower oil hole 102, the second electrode group 32 and the third electrode group 33 have the same polarity, and the first electrode group 31 and the second electrode group 32 have opposite polarities. This setting makes it easier for the magnetic field generated by the electric field generating device 3 to switch between a uniform electric field and a non-uniform electric field. For example:

[0054] The gear adjustment device controls the first electrode group 31 and the second electrode group 32 to be energized, and the third electrode group 33 to be deenergized, and a uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized. When the positive-negative switching device controls the first electrode group 31 to be negative and the second electrode group 32 to be positive, the microcapsule 30 will move toward the direction of the second electrode group 32 driven by the dielectrophoretic force, that is, the microcapsule 30 moves toward the lower oil hole 102, so that the concentration of microcapsules 30 in the atomized liquid around the lower oil hole 102 increases, and the microcapsules 30 will release flavor components when they are ruptured by heat, thereby increasing the content of flavor components during the next inhalation; when the positive-negative switching device controls the first electrode group 31 to be positive and the second electrode group 32 to be negative, the microcapsule 30 will move toward the direction of the first electrode group 31 driven by the dielectrophoretic force, that is, the microcapsule 30 moves away from the lower oil hole 102, thereby decreasing the concentration of microcapsules 30 in the atomized liquid around the lower oil hole 102, thereby preventing the microcapsules 30 from being heated and ruptured by the atomization component 2 to release flavor components, thereby decreasing the content of flavor components during the next inhalation.

[0055] The gear adjustment device controls the first electrode group 31, the second electrode group 32 and the third electrode group 33 to be energized, and the first electrode group 31, the second electrode group 32 and the third electrode group 33 form a non-uniform electric field when energized. When the intensity of the electric field jointly generated by the second electrode group 32 and the third electrode group 33 around the lower oil hole 102 is greater than the intensity of the electric field generated by the first electrode group 31, the microcapsules 30 will move toward the lower oil hole 102 driven by the dielectrophoretic force, so that the concentration of the microcapsules 30 in the atomized liquid around the lower oil hole 102 increases, and the microcapsules 30 will release flavor components when they are ruptured by heat, thereby increasing the content of the flavor components during the next inhalation; when the intensity of the electric field jointly generated by the second electrode group 32 and the third electrode group 33 around the lower oil hole 102 is less than the intensity of the electric field generated by the first electrode group 31, the microcapsules 30 will move away from the lower oil hole 102 driven by the dielectrophoretic force, so that the concentration of the microcapsules 30 in the atomized liquid around the lower oil hole 102 decreases, thereby preventing the microcapsules 30 from being heated and ruptured by the atomization component 2 to release flavor components, thereby reducing the content of the flavor components during the next inhalation.

[0056] In a specific example, the gear adjustment device may be provided with five gear buttons, which correspond to gear I, gear II, gear III, gear IV, and gear V respectively. The intensity of the electric field generated when the first electrode group 31, the second electrode group 32, and the third electrode group 33 are energized is divided into three levels: high, medium, and low. For example:

[0057] When the gear button is touched to put the electronic atomization device in gear position I, the first electrode group 31 and the second electrode group 32 are energized, the third electrode group 33 is not energized, and the intensity of the electric field generated when the first electrode group 31 and the second electrode group 32 are energized is low, so that a uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized.

[0058] When the gear button is touched to put the electronic atomization device in gear II, the first electrode group 31, the second electrode group 32 and the third electrode group 33 are all energized, and the electric field strengths generated by the first electrode group 31, the second electrode group 32 and the third electrode group 33 when energized are all low, so that the first electrode group 31, the second electrode group 32 and the third electrode group 33 form a non-uniform electric field when energized, and the intensity of the electric field jointly generated by the second electrode group 32 and the third electrode group 33 around the lower oil hole 102 is greater than the intensity of the electric field generated by the first electrode group 31.

[0059] When the gear button is pressed to put the electronic atomization device in gear III, the first electrode group 31, the second electrode group 32 and the third electrode group 33 are all de-energized.

[0060] When the gear button is touched to put the electronic atomization device in gear IV, the first electrode group 31 and the third electrode group 33 are energized, the second electrode group 32 is not energized, and the intensity of the electric field generated when the first electrode group 31 and the third electrode group 33 are energized is low, so that a uniform electric field is generated when the first electrode group 31 and the third electrode group 33 are energized.

[0061] When the gear button is touched to put the electronic atomization device in gear position V, the first electrode group 31, the second electrode group 32 and the third electrode group 33 are all energized, and the electric field strength generated when the first electrode group 31 is energized is high, and the electric field strengths generated when the second electrode group 32 and the third electrode group 33 are energized are both low, so that the first electrode group 31, the second electrode group 32 and the third electrode group 33 form a non-uniform electric field when energized, and the intensity of the electric field jointly generated by the second electrode group 32 and the third electrode group 33 around the lower oil hole 102 is less than the intensity of the electric field generated by the first electrode group 31.

[0062] According to actual needs, it can be set that when the gear button is touched to put the electronic atomization device in gear position I, the first electrode group 31, the second electrode group 32 and the third electrode group 33 are all energized, and the intensity of the electric field generated when the first electrode group 31 is energized is medium, and the intensity of the electric field generated when the second electrode group 32 and the third electrode group 33 are energized is low, so that a uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized.

[0063] It should be noted that the capsule membrane of the microcapsule 30 ruptures to release the flavor components when the electric field strength is greater than a preset threshold value. Specifically, under the action of the electric field, the difference in conductivity and dielectric constant on the inner and outer interfaces of the microcapsule 30 generates Maxwell interfacial stress, causing the interface to deform and thus shatter the capsule membrane. When the first electrode group 31, the second electrode group 32, and the third electrode group 33 are energized to form a non-uniform electric field, the closer to the lower oil hole 102, the greater the electric field strength, and the maximum value of the electric field strength is greater than the preset threshold value, so that the capsule membrane of the microcapsule 30 ruptures to release the flavor components under the action of the electric field, and compared with the capsule membrane of the microcapsule 30 rupturing to release the flavor components under the heating of the atomizer assembly 2, the speed at which the microcapsule 30 releases the flavor components can be faster.

[0064] It should be understood that in the embodiment of the present invention, each electrode group is isolated from the atomized liquid so that the electrode group is not connected to the atomized liquid, ensuring that the microcapsule 30 can move in a directional manner under the action of the electric field. When each electrode group is arranged on the inner side of the cavity wall of the liquid storage cavity 11, each electrode group is covered with an insulating film to insulate the electrode group from the atomized liquid; each electrode group can also be arranged on the outer side of the cavity wall of the liquid storage cavity 11 to electrically insulate the electrode group from the atomized liquid.

[0065] The atomized liquid includes at least two different microcapsules 30, and different microcapsules 30 contain different flavor components. In addition, the capsule membranes of different microcapsules 30 have different contents of electrosensitive materials, so that under different electric field strengths, they have different migration speeds, or the microcapsules 30 of different flavor components rupture in different non-uniform electric fields, thereby achieving different flavors and concentration adjustments. Specifically, the atomized liquid can store microcapsules 30 containing nicotine, microcapsules 30 containing essence flavors, and microcapsules 30 containing other plant extracts. The microcapsules 30 containing essence flavors are configured to rupture only in response to an electric field strength greater than a preset threshold, and the microcapsules 30 containing other plant extracts are configured to rupture when heated, so as to adjust the concentration ratio of the mixed flavor aerosol. For example:

[0066] When the gear adjustment device controls the first electrode group 31 and the second electrode group 32 to be energized, and a non-uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized, the microcapsules 30 containing flavors and the microcapsules 30 containing other plant extracts will both rupture, and the taste of the aerosol contains both flavors of flavors and flavors of other plant extracts. When the gear adjustment device controls the first electrode group 31 and the second electrode group 32 to be energized, and a uniform electric field is generated when the first electrode group 31 and the second electrode group 32 are energized, the microcapsules 30 containing only other plant extracts will both rupture, and the taste of the aerosol only contains the taste of other plant extracts.

[0067] In some embodiments, the electronic atomization device also includes a flavor component detection device electrically connected to the control module 201. The flavor component detection device calculates the flavor component content in the atomized liquid by emitting two light signals of different wavelengths to the atomized liquid and collecting the attenuated light signals of two different wavelengths. The control module 201 regulates the electric field generating device 3 to generate a uniform electric field or a non-uniform electric field through the gear adjustment device and the positive and negative pole switching device. For example, still taking the flavor component detection device as a nicotine detection device as an example, the electric field generating device 3 includes a first electrode group 31 and a second electrode group 32 respectively arranged at the top and bottom of the oil cup 1 arranged at intervals. When the nicotine detection device detects that the nicotine content in the atomized liquid is low, the gear adjustment device controls the first electrode group 31 and the second electrode group 32 to generate a uniform electric field when they are energized, and the positive and negative pole switching device controls the first electrode group 31 to be negative and the second electrode group 32 to be positive, so that the microcapsule 30 will move toward the direction of the second electrode group 32 under the drive of the dielectrophoretic force, that is, the microcapsule 30 moves toward the direction of the lower oil hole 102, and the microcapsule 30 is heated by the atomization component 2 to release nicotine, thereby increasing the nicotine content in the atomized liquid. Alternatively, the gear adjustment device controls the first electrode group 31 and the second electrode group 32 to generate a non-uniform electric field when power is supplied, and the intensity of the electric field generated by the second electrode group 32 is greater than the intensity of the electric field generated by the first electrode group 31, so that the microcapsule 30 moves toward the second electrode group 32 driven by the dielectrophoretic force, that is, the microcapsule 30 moves toward the lower oil hole 102, and the microcapsule 30 is heated by the atomization component 2 to release nicotine, thereby increasing the nicotine content in the atomized liquid.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
