[0003] In the related art, the content of flavor components such as nicotine in the atomized liquid in the oil cup is fixed after the electronic atomization device is assembled, and the nicotine content is basically in a uniform state, and the nicotine content cannot be adjusted, thus failing to meet the demand for variable nicotine content during the smoking process. Moreover, the nicotine content will decrease with the use time, and the user will also subjectively feel that the taste has become lighter due to taste fatigue in the later stage of smoking. The taste attenuation caused by subjective and objective reasons affects the smoking experience. Summary of the invention

[0029] Example:

[0030] See also Figure 1 , Figure 2 and Figure 4 The embodiment of the present invention provides an electronic atomization system, including an atomization liquid having a microcapsule 40 and an electronic atomization device. The microcapsule 40 includes a capsule 403, and a flavor component 401 and a magnetic response material 402 disposed in the capsule 403. The magnetic response material 402 is a magnetic particle disposed in the capsule 403. The capsule 403 encloses an inner cavity, and the flavor component 401 is located in the inner cavity, so that the microcapsule 40 releases the flavor component 401 after rupture, and the flavor component 401 is mixed in the aerosol generated by the electronic atomization device and inhaled, thereby changing the user's smoking taste; wherein, the atomization liquid may also contain nicotine and other tobacco extracts, and the flavor component 401 may contain nicotine, and may also contain other flavor materials, such as plant extracts.

[0031] See also Figure 1 and Figure 2The electronic atomization device includes an atomizer 10, which includes an oil cup 1, an atomization core 2 and a magnetic field generating device 3. The oil cup 1 is provided with a liquid storage chamber 11 for storing an atomized liquid containing microcapsules 40, and the microcapsules 40 have a flavor component 401 and a magnetic response material 402; the atomization core 2 is assembled on the oil cup 1, and the atomization core 2 is used to heat the atomized liquid and make at least part of the microcapsules 40 release the flavor component 401; the magnetic field generating device 3 is fixed to the oil cup 1, and the magnetic field generating device 3 is used to generate a magnetic field in the liquid storage chamber 11 to drive the microcapsules 40 to move toward or away from the atomization core 2.

[0032] Because the microcapsule 40 will move towards or away from the atomizer core 2 under the drive of the magnetic field generated by the magnetic field generating device 3, and the atomizer core 2 can heat the atomized liquid and make at least part of the microcapsules 40 release the flavor component 401, taking nicotine as an example, when the microcapsule 40 moves to the atomizer core 2 under the action of the magnetic field, it can be heated and ruptured by the atomizer core 2 to release nicotine, so that the nicotine content in the atomized liquid increases, thereby increasing the nicotine content during the next inhalation; when the microcapsule 40 moves away from the atomizer core 2 under the action of the magnetic field, the nicotine content in the atomized liquid decreases, so that the nicotine content decreases during the next inhalation, so that the nicotine content in the atomized liquid can be controlled by controlling the movement of the microcapsule 40 by the magnetic field generating device 3, thereby meeting the demand for variable nicotine content during the inhalation process and preventing taste attenuation, thereby improving the inhalation experience.

[0033] It should be noted that the microcapsules 40 are insoluble in the atomized liquid and the atomized liquid is not allowed to penetrate into the microcapsules 40; when the taste is too light or too strong during the inhalation process, the magnetic 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 40 are arranged in the liquid storage chamber 11. When the microcapsules 40 move to the atomization core 2, the microcapsules 40 are stacked from bottom to top, so that the atomization core 2 heats the adjacent part of the microcapsules 40 for a period of time.

[0034] See also Figure 4 The magnetic response material 402 is a magnetic particle embedded in the capsule 403. The particle size of the magnetic particles is small, which makes it easy to distribute a large number of magnetic particles in the capsule 403 to ensure that the microcapsule 40 can move towards or away from the atomizer core 2 under the action of the magnetic field; the capsule 403 encloses an inner cavity, and the flavor component 401 is located in the inner cavity, so that after the microcapsule 40 is ruptured by heat, only the flavor component 401 will be released without releasing the magnetic particles, thereby preventing the magnetic particles from being inhaled by the user.

[0035] The magnetic response material 402 includes at least one of iron, cobalt, nickel and iron oxides. The magnetic response material 402 is preferably iron oxide, such as ferroferric oxide, which is low in cost and easy to process into particles. The material of the capsule membrane 403 of the microcapsule 40 includes an organic phase change material, which is used to rupture the microcapsule 40 when heated, wherein the organic phase change material will generate vapor pressure to rupture the microcapsule 40 when heated, and the organic phase change material can be paraffin and polyols. For example, the capsule membrane 403 of the microcapsule 40 uses paraffin as the core material and melamine-urea-formaldehyde prepolymer as the wall material, and is prepared by in-situ polymerization; uses ethylene glycol wrapped on the surface of paraffin to form a core material, and a carboxymethyl cellulose film doped with nano TiO2 particles as the wall material; uses polyols as the core material, and urea-formaldehyde resin and olefin polymers as the wall material.

[0036] See also Figure 1 The electronic atomization device also includes a shell 20 and a control component 30. The control component 30 is fixed in the shell 20. The atomizer 10 is fixed to the shell 20, and the control component 30 is electrically connected to the atomization core 2 and the magnetic field generating device 3 respectively. The control component 30 is used to supply power to the atomization core 2 and control the magnetic field generating device 3 to generate a magnetic field.

[0037] In some embodiments, the magnetic field generating device 3 includes at least two magnetic field generators spaced apart from each other on the oil cup 1, and the at least two magnetic field generators interact with each other to form a magnetic field with variable magnetic field strength and / or variable magnetic field direction. That is, in an embodiment of the invention, the magnetic field generating device 3 has a plurality of settings on the oil cup 1 to generate a magnetic field that drives the microcapsule 40 to move toward or away from the atomization core 2.

[0038] See also Figure 2 In a specific example, the magnetic field generating device 3 includes a first magnetic field generator 31 and a second magnetic field generator 32 respectively arranged at the top and bottom of the oil cup 1 arranged at intervals, and the atomizing core 2 is arranged at the bottom of the oil cup 1 and communicated with the liquid storage chamber 11. The first magnetic field generator 31 and the second magnetic field generator 32 interact with each other to generate a magnetic field with variable magnetic field intensity and / or variable magnetic field direction. In this arrangement, the number of the first magnetic field generator 31 and the second magnetic field generator 32 required is small, which is conducive to reducing costs and reducing installation difficulty; and there is no requirement for the magnetic size and mass of the microcapsule 40, which can reduce the difficulty of preparing the microcapsule 40, for example:

[0039] The magnetic field strengths of the magnetic fields generated by the first magnetic field generator 31 and the second magnetic field generator 32 are both variable. When the magnetic field strength generated by the second magnetic field generator 32 is greater than the magnetic field strength generated by the first magnetic field generator 31, the microcapsule 40 will move in the direction of the large magnetic field strength, so that the microcapsule 40 can move in the direction of the second magnetic field generator 32, ensuring that the microcapsule 40 can move in the direction close to the atomizer core 2, so that the microcapsule 40 can be heated by the atomizer core 2 to release nicotine. Among them, the first magnetic field generator 31 and the second magnetic field generator 32 can both generate magnetic fields, and the magnetic field strength generated by the second magnetic field generator 32 is greater than the magnetic field strength generated by the first magnetic field generator 31; or, the first magnetic field generator 31 does not generate a magnetic field, and the second magnetic field generator 32 generates a magnetic field, so that the magnetic field strength generated by the second magnetic field generator 32 is greater than the magnetic field strength generated by the first magnetic field generator 31. It should be noted that when the first magnetic field generator 31 generates a magnetic field and the second magnetic field generator 32 does not generate a magnetic field, the microcapsule 40 will move in the direction away from the atomizer core 2.

[0040] The magnetic field strength generated by the second magnetic field generator 32 is variable, and the magnetic field strength generated by the first magnetic field generator 31 is constant. When the second magnetic field generator 32 generates a magnetic field and the magnetic field strength is greater than the magnetic field strength generated by the first magnetic field generator 31, the microcapsule 40 moves toward the direction close to the atomizer core 2; when the second magnetic field generator 32 does not generate a magnetic field or the second magnetic field generator 32 generates a magnetic field and the magnetic field strength is less than the magnetic field strength generated by the first magnetic field generator 31, the microcapsule 40 moves toward the direction away from the atomizer core 2.

[0041] The magnitude of the magnetic field strength generated by the first magnetic field generator 31 is set equal to the magnitude of the magnetic field strength generated by the second magnetic field generator 32, and the directions of the magnetic fields generated by the first magnetic field generator 31 and the second magnetic field generator 32 can be changed. Among them, the magnetic poles corresponding to the first magnetic field generator 31 and the second magnetic field generator 32 attract each other, and the magnetic poles corresponding to the first magnetic field generator 31 and the second magnetic field generator 32 are changeable, and the specific implementation method is as follows:

[0042] When the magnetic pole corresponding to the first magnetic field generator 31 is the S pole and the magnetic pole corresponding to the second magnetic field generator 32 is the N pole, the direction of the magnetic field is from the bottom of the oil cup 1 to the top of the oil cup 1, so that the microcapsule 40 moves away from the atomizer core 2, and the atomizer core 2 cannot heat the microcapsule 40 to release nicotine, and the nicotine content in the atomized liquid decreases, so that the nicotine content in the aerosol decreases during the next puff. When the magnetic pole corresponding to the first magnetic field generator 31 is the N pole and the magnetic pole corresponding to the second magnetic field generator 32 is the S pole, the direction of the magnetic field is from the top of the oil cup 1 to the bottom of the oil cup 1, so that the microcapsule 40 moves toward the atomizer core 2, and the atomizer core 2 heats the microcapsule 40 to release nicotine, and the nicotine content in the atomized liquid increases, so that the nicotine content in the aerosol increases during the next puff.

[0043] See also Figure 1 In a specific example, the atomizer 10 also includes a ventilation pipe 5 respectively connected to the bottom and top of the oil cup 1 and located in the liquid storage chamber 11, and the atomizer core 2 is arranged in the ventilation pipe 5; the magnetic field generating device 3 includes a first magnetic field generator 31 arranged on the inner circumferential wall of the oil cup 1 and a second magnetic field generator 32 arranged outside the ventilation pipe 5 and facing the first magnetic field generator 31. The first magnetic field generator 31 and the second magnetic field generator 32 interact with each other to generate a magnetic field with variable magnetic field intensity and / or variable magnetic field direction. This arrangement is conducive to reducing the difficulty of installing the atomizer core 2, and the path for the microcapsule 40 to move to the atomizer core 2 is short, which is conducive to improving the response speed of the microcapsule 40.

[0044] It should be noted that the first magnetic field generator 31 and the second magnetic field generator 32 are both distributed in the circumferential direction, and the first magnetic field generator 31 and the second magnetic field generator 32 can be ring-shaped; the magnetic field intensity and direction generated by the first magnetic field generator 31 and the second magnetic field generator 32 are the same as those in the aforementioned example, and no relevant description is given here.

[0045] It should be understood that the first magnetic field generator 31 and the second magnetic field generator 32 can be arranged in the liquid storage chamber 11 or outside the liquid storage chamber 11 according to the oil discharge position; when the number of magnetic field generators exceeds three, the magnetic field generated by the magnetic field generating device 3 is a composite magnetic field formed by superimposing the magnetic fields generated by multiple magnetic field generators, and the composite magnetic field can drive the microcapsule 40 to move toward or away from the liquid inlet hole 102.

[0046] In some embodiments, the atomizing core 2 is arranged at the bottom of the oil cup 1, and the magnetic field generating device 3 includes a magnetic field generator arranged at the top of the oil cup 1, and the magnetic field generator generates a magnetic field with a variable magnetic field strength, and the mass size or magnetic size of each microcapsule 40 is set differently. Among them, when the magnetic field generator is started, the microcapsules 40 are all attracted by the magnetic force of the magnetic field generator and are at the top of the oil cup 1. At this time, the magnetic force of the microcapsules 40 is balanced with the gravity they are subjected to. Since the mass size or magnetic size of each microcapsule 40 is set differently, when the magnetic field strength generated by the magnetic field generator is smaller, more microcapsules 40 are subjected to gravity greater than the magnetic attraction force, more microcapsules 40 fall, and the nicotine content in the atomized liquid is higher. For example, the microcapsules 40 are provided with three levels of mass size: large, medium and small. When the magnetic field strength generated by the magnetic field generator gradually decreases, the microcapsules 40 with smaller mass fall first, then the microcapsules 40 with medium mass fall, and finally the microcapsules 40 with larger mass fall.

[0047] In some embodiments, the atomizer core 2 is disposed at the bottom of the oil cup 1, and the magnetic field generating device 3 includes a plurality of magnetic field generators disposed on the periphery of the oil cup 1, and the plurality of magnetic field generators are continuously distributed in the longitudinal direction, and the magnetic poles corresponding to two adjacent magnetic field generators attract each other, and the magnetic poles corresponding to the magnetic field generators are variable. It should be understood that at this time, the magnetic field generating device 3 and the microcapsule 40 constitute a linear motor, wherein the magnetic field generating device 3 is the stator of the linear motor, and the microcapsule 40 is the mover of the linear motor, and by changing the magnetic poles corresponding to two adjacent magnetic field generators, the microcapsule 40 is driven to move toward or away from the atomizer core 2.

[0048] For example, the magnetic field generating device 3 includes three magnetic field generators, which are continuously distributed in the longitudinal direction, and the electrodes at both ends of the microcapsule 40 are respectively the N pole and the S pole. When the first magnetic field generator is powered on, the magnetic pole of the first magnetic field generator is the N pole, and the S pole of the microcapsule 40 is magnetically attracted by the first magnetic field generator to be directly opposite to the first magnetic field generator; then the second magnetic field generator is powered on, the magnetic pole of the second magnetic field generator is the N pole, and the magnetic pole of the first magnetic field generator is changed to the S pole, at which time the microcapsule 40 is repelled by the first magnetic field generator and magnetically attracted by the second magnetic field generator, and the microcapsule 40 moves toward the second magnetic field generator until the S pole of the microcapsule 40 is magnetically attracted by the second magnetic field generator to be directly opposite to the second magnetic field generator, and the N pole is attracted. The first magnetic field generator is magnetically attracted to a position facing the first magnetic field generator; then the third magnetic field generator is powered on, and the magnetic pole of the third magnetic field generator becomes the N pole. At the same time, the first magnetic field generator is powered off, and the magnetic pole of the second magnetic field generator becomes the S pole. At this time, the microcapsule 40 is repelled by the second magnetic field generator and magnetically attracted by the third magnetic field generator. The microcapsule 40 moves toward the third magnetic field generator until the S pole of the microcapsule 40 is magnetically attracted by the third magnetic field generator to a position facing the third magnetic field generator, and the N pole is magnetically attracted by the second magnetic field generator to a position facing the second magnetic field generator.

[0049] See also Figure 3 , the magnetic field generator is a magnetic induction coil 33, or the magnetic field generator is an electromagnet. When the magnetic field generator is a magnetic induction coil 33, as Figure 3 As shown, the magnetic induction coil 33 can be a flexible thin film planar coil, which is convenient to be arranged according to the shape of the atomizer 10, occupies little internal space, and is convenient for miniaturization of the atomizer 10. The magnetic field generator includes a flexible substrate and a planar coil arranged on the flexible substrate, and the planar coil generates a magnetic field when energized; or, the magnetic induction coil 33 can be a coil coating formed on the shell 4 of the oil cup 1 by coating, printing, or deposition, wherein the magnitude of the current passed through the magnetic induction coil 33 or the number of coil turns can be changed to change the magnitude of the magnetic field intensity, and the direction of the current passed through the magnetic induction coil 33 can be changed to change the direction of the magnetic field. When the magnetic field generator is an electromagnet, the number of electromagnets or the magnitude of the current passed through can be changed to change the magnitude of the magnetic field intensity, and the direction of the current passed through the electromagnet can be changed to change the direction of the magnetic field.

[0050] In a specific example, the first magnetic field generator 31 and the second magnetic field generator 32 are both magnetic induction coils 33, and the strength of the magnetic field generated by the first magnetic field generator 31 and the second magnetic field generator 32 is positively correlated with the number of turns of the magnetic induction coils 33; wherein, the number of turns of the magnetic induction coils 33 of the first magnetic field generator 31 and the second magnetic field generator 32 may be the same or different, for example, the number of turns of the magnetic induction coil 33 of the first magnetic field generator 31 is less than the number of turns of the magnetic induction coil 33 of the second magnetic field generator 32, so that the magnetic field strength generated by the second magnetic field generator 32 is greater than the magnetic field strength generated by the first magnetic field generator 31.

[0051] Alternatively, the magnitude of the magnetic field strength generated by the first magnetic field generator 31 and the second magnetic field generator 32 is positively correlated with the magnitude of the current passed through. At this time, the number of turns of the magnetic induction coils 33 of the first magnetic field generator 31 and the second magnetic field generator 32 is the same, and the current passed through the magnetic induction coil 33 of the second magnetic field generator 32 is greater than the current passed through the magnetic induction coil 33 of the first magnetic field generator 31, so that the magnetic field strength generated by the second magnetic field generator 32 is greater than the magnetic field strength generated by the first magnetic field generator 31.

[0052] The atomizer 10 is provided with an air flow channel 101 isolated from the liquid storage chamber 11 and a liquid inlet hole 102 connecting the air flow channel 101 and the liquid storage chamber 11. The atomizer core 2 is at least partially located in the air flow channel 101 and covers the liquid inlet hole 102. The direction of the magnetic field generated by the magnetic field generating device 3 is toward or away from the liquid inlet hole 102. For example:

[0053] See also Figure 2 In a specific example, the housing 20 and the control assembly 30 together constitute a battery rod assembly, the atomizer 10 is detachably connected to one end of the battery rod assembly, the atomizer 10 also includes a shell 4 having a accommodating cavity, the oil cup 1 is fixed in the accommodating cavity, the air flow channel 101 is formed between the oil cup 1 and the inner circumferential wall of the shell 4, and the magnetic field generating device 3 includes a first magnetic field generator 31 and a second magnetic field generator 32 respectively arranged at the top and bottom of the oil cup 1 spaced apart.

[0054] See also Figure 1 In a specific example, the atomizer 10 is fixed in the housing 20, and the atomizer 10 also includes a ventilation pipe 5 respectively connected to the bottom and the top of the oil cup 1 and located in the liquid storage chamber 11, the ventilation pipe 5 is provided with an air flow channel 101, the atomization core 2 is arranged in the ventilation pipe 5, and the magnetic field generating device 3 includes a first magnetic field generator 31 arranged on the inner circumferential wall of the oil cup 1 and a second magnetic field generator 32 arranged outside the ventilation pipe 5 and opposite to the first magnetic field generator 31.

[0055] It should be noted that the atomizer core 2 covers the liquid inlet hole 102, and the aperture of the liquid inlet hole 102 is larger than the diameter of nicotine, so that nicotine can be mixed in the aerosol generated by heating the atomizer liquid, thereby increasing the nicotine content in the aerosol.

[0056] In some embodiments, the electronic atomization device further includes a flavor component detection device and a positive and negative switching circuit electrically connected to the control component 30. 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 two light signals of different wavelengths after attenuation. The control component 30 adjusts the input current size or current direction of the magnetic field generating device 3, thereby changing the magnetic field strength size or magnetic field direction generated by the magnetic field generating device 3. For example, still taking the flavor component detection device as a nicotine detection device as an example, the magnetic field generating device 3 includes a first magnetic field generator 31 and a second magnetic field generator 32 respectively arranged at the top and bottom of the oil cup 1 spaced apart. When the nicotine detection device detects that the nicotine content in the atomized liquid is low, the control component 30 controls the current passed into the second magnetic field generator 32 to be greater than the current of the first magnetic field generator 31, so that the intensity of the magnetic field generated by the second magnetic field generator 32 is greater than the intensity of the magnetic field generated by the first magnetic field generator 31, so that the microcapsule 40 moves toward the direction close to the atomization core 2 under the action of the magnetic field generated by the magnetic field generating device 3, and the microcapsule 40 is heated by the atomization core 2 to release nicotine, thereby increasing the nicotine content in the atomized liquid. Alternatively, the control component 30 adjusts the input current direction of the first magnetic field generator 31 and the second magnetic field generator 32 through the positive and negative switching circuit, such as the magnetic pole corresponding to the magnetic field generator at the top of the oil cup 1 is the N pole and the magnetic pole corresponding to the magnetic field generator at the bottom of the oil cup 1 is the S pole, the microcapsule 40 moves toward the atomizer core 2, and the microcapsule 40 is heated by the atomizer core 2 to release nicotine, thereby increasing the nicotine content in the atomized liquid.

[0057] 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.
