[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

[0030] Example:

[0031] See also Figure 1 The embodiment of the present invention provides an electronic atomization device, including a housing, a control component 10 and an atomizer. The control component 10 is fixed in the housing, the atomizer is fixed to one end of the housing, and the control component 10 is electrically connected to the atomizer; wherein the atomizer and the housing can be integrally arranged or detachably connected.

[0032] See also Figure 1 , Figure 2 and Figure 3 The atomizer includes an oil cup 1, a microcapsule 20, a diaphragm 2, an atomizing assembly 3 and a light source assembly. The oil cup 1 is provided with a liquid storage chamber 13 for storing atomized liquid and a receiving chamber 14 for storing microcapsules 20 having flavor components; the diaphragm 2 is fixed in the oil cup 1 and separates the liquid storage chamber 13 and the receiving chamber 14; the atomizing assembly 3 is fixed in the liquid storage chamber 13, and the atomizing assembly 3 is used to heat the atomized liquid to generate aerosol and heat the microcapsules 20 to release flavor components; the light source assembly is provided on one side of the diaphragm 2, and the light source assembly is used to emit a light beam to irradiate the diaphragm 2 to change the permeability of the diaphragm 2.

[0033] Since the light beam emitted by the light source assembly illuminates the diaphragm 2, the permeability of the diaphragm 2 can be changed. When the diaphragm 2 is illuminated by the light beam, the microcapsules 20 in the accommodating cavity 14 can flow into the liquid storage cavity 13. The microcapsules 20 in the liquid storage cavity 13 are heated by the atomizing assembly 3 to release the flavor components, so that the flavor components in the atomized liquid rise, thereby increasing the content of the flavor components during inhalation. When the diaphragm 2 is not illuminated by the light beam, the microcapsules 20 cannot penetrate through the diaphragm 2, and the content of the microcapsules 20 in the atomized liquid decreases, thereby decreasing the content of the flavor components in the atomized liquid, thereby decreasing the content of the flavor components during inhalation. Therefore, the content of the flavor components in the atomized liquid can be controlled by the light source assembly, thereby meeting the demand for the flavor component content to be variable during inhalation and preventing taste attenuation, thereby improving the inhalation experience.

[0034] It should be noted that the microcapsule 20 is insoluble in the atomized liquid and the atomized liquid is not allowed to penetrate into the microcapsule 20; the diaphragm 2 is a photosensitive membrane, and the diaphragm 2 does not allow the atomized liquid to penetrate into the accommodating chamber 14; the flavor component is not limited to nicotine particles, and may also include other flavor materials, such as plant extracts and fruit extracts; the control component 10 is electrically connected to the atomization component 3 and the light source component, respectively, to control the light intensity and opening and closing of the light source component, and control the opening or closing of the atomization component 3.

[0035] The permeability of the diaphragm 2 is positively correlated with the light intensity, that is, the greater the light intensity of the light beam emitted by the light source assembly, the greater the permeability of the diaphragm 2, the easier it is for the microcapsules 20 to penetrate through the diaphragm 2, and the greater the number of microcapsules 20 that penetrate through the diaphragm 2 per unit time, so that the content of microcapsules 20 in the atomized liquid can be accurately controlled by controlling the light intensity of the light beam emitted by the light source assembly. Among them, the material made of the diaphragm 2 includes azobenzene that can switch between cis and trans isomers under light, such as a composite film formed by azobenzene bridged with tetraazacyclododecane, bacterial cellulose nanocrystal / chiral azobenzene composite film, azobenzene-based fluorinated copolymer composite film, etc. According to actual needs, the material made of the diaphragm 2 can also be a photosensitive resin composition.

[0036] In some specific embodiments, an air flow channel 5 isolated from the liquid storage chamber 13 and the accommodating chamber 14 is provided in the oil cup 1, and a lower oil hole 6 connected to the liquid storage chamber 13 is provided on the side wall of the air flow channel 5, and the atomization assembly 3 is arranged in the air flow channel 5 and covers the lower oil hole 6.

[0037] In some embodiments, a plurality of independently arranged accommodating cavities 14 along the circumference or axial direction of the liquid storage cavity 13 are provided in the atomizer, and the light source assembly includes a plurality of illumination light sources 4 fixed to the oil cup 1, and the plurality of illumination light sources 4 are arranged one-to-one corresponding to the plurality of accommodating cavities 14 to ensure that the microcapsules 20 in each accommodating cavity 14 can flow into the liquid storage cavity 13; moreover, the plurality of illumination light sources 4 are independent of each other and can respectively control the permeability of the diaphragm 2 corresponding to each accommodating cavity 14, thereby realizing time-sharing and zone-sharing control of the microcapsules 20 in the plurality of accommodating cavities 14 flowing into the liquid storage cavity 13.

[0038] In some examples, such as Figure 1 As shown, two accommodating cavities 14 may be provided in the atomizer, and the two accommodating cavities 14 are independently distributed along the circumferential direction. The light source assembly is provided with two irradiation light sources 4 arranged in one-to-one correspondence with the two accommodating cavities 14 .

[0039] In other examples, such as Figure 3 As shown, four accommodating cavities 14 may be provided in the atomizer, and the four accommodating cavities 14 are independently distributed in pairs along the axial direction or the circumferential direction. The light source assembly is provided with four irradiation light sources 4 arranged in a one-to-one correspondence with the four accommodating cavities 14 .

[0040] It is understood that in other embodiments, when there is a single accommodating cavity 14 in the atomizer, the light source assembly may also have multiple irradiation light sources 4. Similarly, when there are multiple accommodating cavities 14, the light source assembly may also have multiple irradiation light sources 4.

[0041] It should be noted that the irradiation light source 4 can be set at any position in the oil cup 1, as long as the light beam emitted by the irradiation light source 4 can irradiate the diaphragm 2. The irradiation component can also be a light strip, which is fixed on the cavity wall 12, and the LED lamp beads on the light strip are evenly distributed on the cavity wall 12, and the LED lamp beads on the light strip can be controlled by partitions, and multiple partitions correspond to multiple accommodating cavities 14.

[0042] See also Figure 2 In some embodiments, the atomizer and the housing are detachably connected, the oil cup 1 includes a housing 11, a cavity wall 12 disposed in the housing 11 and defining a storage space, and a partition wall disposed in the cavity wall 12, the partition wall divides the storage space into a liquid storage cavity 13 and a receiving cavity 14, the partition wall is at least partially formed by a diaphragm 2, and when the diaphragm 2 is irradiated by a light beam emitted by a light source assembly, the receiving cavity 14 communicates with the liquid storage cavity 13 through the diaphragm 2, so that the microcapsules 20 in the receiving cavity 14 can flow into the liquid storage cavity 13, thereby changing the content of the microcapsules 20 in the atomized liquid. This arrangement can reduce the demand for the diaphragm 2, which is conducive to reducing costs.

[0043] Among them, Figure 2As shown, the partition wall is a diaphragm 2, which is arranged between the top and the bottom of the cavity wall 12. The diaphragm 2 divides the storage space into a accommodating cavity 14 located above and a liquid storage cavity 13 located below, so that the microcapsules 20 can penetrate through the diaphragm 2 under the action of gravity, which is beneficial for the microcapsules 20 to flow into the liquid storage cavity 13; moreover, the volume of the accommodating cavity 14 should be smaller than the volume of the liquid storage cavity 13, so that more atomized liquid can be stored in the limited storage space of the oil cup 1, thereby allowing the electronic atomization device to have a longer suction time.

[0044] The light source assembly may be directly or indirectly connected to the cavity wall 12, for example, Figure 2 As shown, the illumination light source 4 is arranged on the top of the cavity wall 12, and the illumination light source 4 is arranged in the accommodating cavity 14, so that the light beam emitted by the illumination light source 4 can be directly irradiated on the diaphragm 2 (without transmitting through the cavity wall 12). At the same time, since there is no atomized liquid in the accommodating cavity 14, the atomized liquid can be prevented from affecting the illumination light source 4.

[0045] Among them, Figure 2 As shown, an airflow channel 5 is formed between the housing 11 and the outer side of the cavity wall 12, the cavity wall 12 is provided with a lower oil hole 6 connected to the liquid storage cavity 13, and the atomizer assembly 3 is at least partially located in the airflow channel 5 and is in fluid communication with the liquid storage cavity 13 through the lower oil hole 6, so that the aerosol generated by the atomization liquid heated by the atomizer assembly 3 and the flavor components released by the heated microcapsules 20 are both inhaled through the airflow channel 5. Specifically, the lower oil hole 6 is provided at the bottom of the cavity wall 12, and the atomizer assembly 3 is fixed to the bottom of the housing 11 and covers the lower oil hole 6.

[0046] As an example, in this embodiment, there is one accommodating cavity 14 and one irradiation light source 4. According to actual needs, there can be multiple irradiation light sources 4, such as two or three, which are evenly distributed on the top of the cavity wall 12 to improve the illumination intensity.

[0047] See also Figure 3In some embodiments, the inner side wall of the cavity wall 12 is provided with one or more receiving grooves arranged at intervals and having notches, and the partition wall is a diaphragm 2, and the diaphragm 2 covers the notch of each receiving groove to form a receiving cavity 14. Specifically, there are four receiving grooves, wherein two receiving grooves are respectively provided at the top and the bottom of the cavity wall 12, so that there are four receiving cavities 14, and the four receiving cavities 14 surround the liquid storage cavity 13, so that the distribution of the microcapsules 20 flowing from the receiving cavity 14 to the liquid storage cavity 13 is more uniform. Moreover, the notch of each receiving groove can be covered by a separate diaphragm 2, that is, the diaphragms 2 can be correspondingly provided with four. Compared with a whole diaphragm 2 covering the notch of a receiving groove, the area of ​​a single diaphragm 2 is smaller, which is conducive to fixing the diaphragm 2. Of course, the diaphragm 2 in this embodiment can also be set as a whole piece. According to actual needs, there can also be one containing groove, that is, there is one containing chamber 14, in which case the longitudinal section of the diaphragm 2 is U-shaped; there is only one containing groove, so that its groove opening is relatively large, which is beneficial to increase the number of microcapsules 20 that penetrate from the containing chamber 14 through the diaphragm 2 and flow into the liquid storage chamber 13 per unit time.

[0048] Among them, Figure 3 As shown, the illumination light source 4 of the light source assembly can be arranged on the peripheral side of the cavity wall 12, and a light source assembly is separately provided in each accommodating cavity 14, that is, four illumination light sources 4 are provided, so that the changes in the permeability of the multiple diaphragms 2 corresponding to the multiple accommodating cavities 14 are independent of each other, so that the microcapsules 20 in the multiple accommodating cavities 14 can flow into the liquid storage cavity 13 in time and region.

[0049] It should be noted that the arrangement of other components of the atomizer in this embodiment is the same as the arrangement of other components of the atomizer in the previous embodiment, such as the arrangement of the airflow channel 5, the arrangement of the atomization assembly 3, etc. In order to avoid repeated description, relevant description is not given here.

[0050] See also Figure 1 Combined with Figure 2 In some embodiments, the atomizer and the housing are integrally provided, and the cavity wall 12 is the shell 11 of the oil cup 1, that is, the oil cup 1 and the housing are integrally provided. Specifically, the atomizer further includes a vent pipe 7 located in the oil cup 1 and connected at both ends to the bottom and the top of the oil cup 1, respectively. The vent pipe 7 defines at least part of the air flow channel 5, and the side wall of the vent pipe 7 is provided with a lower oil hole 6. The atomizer assembly 3 is disposed in the vent pipe 7 and covers the lower oil hole 6, and the atomizer assembly 3 is in fluid communication with the liquid storage chamber 13 through the lower oil hole 6. Since the cavity wall 12 is the shell 11 of the oil cup 1, and the atomizer and the housing are integrally provided, the molding method of the oil cup 1 is simpler.

[0051] Among them, Figure 1As shown, a partition wall is provided between the vent pipe 7 and the cavity wall 12, and the partition wall is a diaphragm 2. A liquid storage cavity 13 is formed between the diaphragm 2 and the outer side of the vent pipe 7, and a receiving cavity 14 is formed on the side of the diaphragm 2 away from the vent pipe 7. Two receiving cavities 14 are provided, and the two receiving cavities 14 are independently distributed along the circumferential direction.

[0052] Among them, Figure 1 As shown, the illumination light source 4 of the light source assembly is arranged on the top of the oil cup 1, and the illumination light source 4 is arranged in the liquid storage cavity 13; there are two illumination light sources 4, and the two illumination light sources 4 are distributed on both sides of the ventilation pipe 7 to ensure that the light beams emitted by the two illumination light sources 4 can respectively illuminate the diaphragms 2 corresponding to the two accommodating cavities 14.

[0053] It is understandable that in the above embodiment, the diaphragm 2 can also be a closed annular structure arranged around the outer circumference of the ventilation pipe 7, that is, a basically coaxially arranged annular columnar liquid storage chamber 13 and an annular columnar accommodating chamber 14 are formed in the oil cup 1.

[0054] The capsule membrane of the microcapsule 20 is made of an organic phase change material, which is used to generate vapor pressure when heated to rupture the microcapsule 20. Specifically, the organic phase change material can be paraffin and polyols. For example, the capsule membrane of the microcapsule 20 uses paraffin as the core material and melamine-urea-formaldehyde prepolymer as the wall material, and is prepared by in-situ polymerization; uses a core material composed of ethylene glycol wrapped on the surface of paraffin 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.

[0055] See also Figure 1 , Figure 2 and Figure 3 The atomizer further comprises a detection device electrically connected to the atomizing assembly 3, and the detection device detects the content of the microcapsules in the liquid storage chamber 13. The detection device may be a sensor that directly or indirectly detects a parameter value in the atomized liquid that can characterize the content of the microcapsules in the liquid storage chamber 12, such as a concentration sensor.

[0056] In some specific embodiments, the detection device includes an optical signal emitting component 8, an optical signal receiving component 9 and a circuit board. The optical signal emitting component 8, the optical signal receiving component 9 and the atomizing component 3 are all electrically connected to the circuit board, the optical signal emitting component 8 is used to emit a detection optical signal into the liquid storage chamber 13, the optical signal receiving component 9 is used to receive a reflected optical signal reflected by the microcapsule 20, and the circuit board is used to calculate the content of the microcapsules 20 in the atomized liquid according to the detection optical signal and the reflected optical signal. Among them, the optical signal emitting component 8 can be a lamp, and the optical signal receiving component 9 can be a light receiving element, such as a photodiode, wherein the detection optical signal can be different from the light beam emitted by the light source component, for example: the detection optical signal and the light emitted by the light source component are of different frequencies to avoid affecting the accuracy of the detection of the content of the microcapsules 20.

[0057] When the detection device detects that the content of microcapsules 20 in the atomized liquid is low, the control component 10 controls the light source component to turn on, and controls the light source component to emit a light beam of a predetermined light intensity so that the microcapsules 20 can penetrate through the diaphragm 2 to flow into the atomized liquid, so that the content of microcapsules 20 in the atomized liquid increases, and the atomizing component 3 heats the microcapsules 20 to release the flavor components, so that the content of the flavor components increases during the next puff. When the detection device detects that the content of microcapsules 20 in the atomized liquid is high, the control component 10 controls the light source component to turn off, so that the content of microcapsules 20 in the atomized liquid decreases, so that the content of the flavor components decreases during the next puff.

[0058] Preferably, the optical signal transmitting component 8 and the optical signal receiving component 9 are arranged on the same side of the oil cup 1 to prevent the other light sources from directly affecting the collection of the reflected light signal. For example, the optical signal transmitting component 8 and the optical signal receiving component 9 are both arranged on the bottom side of the oil cup 1. Figure 2 and Figure 3 As shown, the optical signal transmitting component 8 and the optical signal receiving component 9 can be arranged at intervals from the lower oil hole 6, or, as shown in FIG. Figure 3 As shown, the optical signal transmitting component 8 and the optical signal receiving component 9 can be arranged with the ventilation tube 7 spaced apart. The capsule membrane of the microcapsule 20 can reflect the light beam back under the irradiation of the light beam, and the wavelength of the reflected light beam is significantly different from the wavelength of the incident light beam, so as to avoid the incident light beam affecting the collection of the reflected signal; wherein, the capsule membrane of the microcapsule 20 is made of a reflective material, which includes a reflective medium and a light wave regulating medium, the reflective medium can be titanium dioxide, and the light wave regulating medium can be a rare earth material.

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.
