[0029] Example:

[0030] See also Figure 1 , an embodiment of the present invention provides an electronic atomization device, including a battery rod assembly and an atomizer. The battery rod assembly includes a shell, a power supply 5 and a control board, both of which are fixed in the shell, and the control board is electrically connected to the power supply 5 and the atomizer, the power supply 5 is used to power the atomizer, and the control board is used to control the start and shut down of the atomizer. In one embodiment, the battery rod assembly and the atomizer are integrally arranged, that is, the shell and the atomizer are connected as a whole. According to actual needs, the battery rod assembly and the atomizer can be separately arranged.

[0031] See also Figure 1 and Figure 3The atomizer includes a shell 1, a sound field generating device 2 and an atomizing assembly 3. The shell 1 is provided with a liquid storage chamber 111, a connecting channel 12 and an air outlet channel 13. The liquid storage chamber 111 is used to store atomized liquid with flavor microcapsules. The connecting channel 12 connects the liquid storage chamber 111 and the air outlet channel 13 respectively. The air outlet channel 13 is at least partially exposed on the outside of the shell 1. The sound field generating device 2 is fixed in the shell 1. The sound field generating device 2 is used to generate a first sound field for driving the flavor microcapsules to flow from the liquid storage chamber 111 to the connecting channel 12, and a second sound field for generating a second sound field for causing the flavor microcapsules to rupture in the connecting channel 12. The atomizing assembly 3 is fixed in the shell 1. The atomizing assembly 3 is at least partially located in the air outlet channel 13 and is in fluid communication with the liquid storage chamber 111. The atomizing assembly 3 is used to heat the atomized liquid in the atomized liquid storage chamber 111 to generate an aerosol. The connecting portion between the liquid storage chamber 111 and the connecting channel 12 is configured to allow only the flavor microcapsules to flow through. The first sound field and the second sound field are independent of each other, and the sound field intensity of the first sound field is less than the sound field intensity of the second sound field.

[0032] When the sound field generating device 2 generates the first sound field, the flavor microcapsules flow from the liquid storage chamber 111 to the connecting channel 12 under the drive of the first sound field; when the sound field generating device 2 generates the second sound field, the flavor microcapsules are broken under the action of the second sound field, and the flavor particles are distributed in the connecting channel 12. During inhalation, the atomizing component 3 heats the atomized liquid in the atomizing liquid storage chamber 111 to generate an aerosol, and the aerosol will flow into the air outlet channel 13, and the flavor particles will flow from the connecting channel 12 to the air outlet channel 13, so that the aerosol can be entrained with the flavor particles and inhaled by the user, so that the content of the flavor particles in the connecting channel 12 can be increased or decreased by controlling the sound field generating device 2 to start or stop, so that the flavor component content of the aerosol increases or decreases during the next inhalation, meeting the demand that the flavor component content can be changed during the inhalation process and preventing the flavor from decaying, thereby improving the inhalation experience.

[0033] It should be noted that the flavor microcapsules are subjected to a first acoustic radiation force in the first acoustic field, which drives the flavor microcapsules to flow from the liquid storage chamber 111 to the connecting channel 12; the first acoustic radiation force is smaller than the surface tension of the flavor microcapsule membrane, thereby preventing the flavor microcapsules from rupturing. The flavor microcapsules are subjected to a second acoustic radiation force in the second acoustic field, which is larger than the surface tension of the flavor microcapsule membrane, thereby rupturing the flavor microcapsules.

[0034] In the embodiment of the present invention, the flavor microcapsule is not limited to the microcapsule containing nicotine particles, but may also be a microcapsule containing other flavor components, such as fruit extract particles and plant extract particles.

[0035] The sound field generating device 2 includes a first sound field generator and a second sound field generator. The first sound field generator is used to generate ultrasonic waves that propagate from the liquid storage chamber 111 toward the connecting channel 12 to form a first sound field. The second sound field generator is used to generate ultrasonic waves that only cover the connecting channel 12 and rupture the flavor microcapsules to form a second sound field. Specifically, the first sound field generator can be arranged on a side of the liquid storage chamber 111 away from the connecting channel 12, and the second sound field generator can be arranged on a side of the liquid storage chamber 111 where the connecting channel 12 is arranged. The first sound field generator and the second sound field generator are electrically connected to the control board respectively, so that the first sound field generator and the second sound field generator can generate the first sound field and the second sound field independently of each other.

[0036] See also Figure 1 and Figure 2 The housing 1 is also provided with a microcapsule forming channel 14 connected to the liquid storage chamber 111, and the microcapsule forming channel 14 stores flavor particles and capsule medium, and the sound field generating device 2 also includes a third sound field generator, which is used to generate a third sound field for driving the flavor particles to move in the microcapsule forming channel 14 and be wrapped by the capsule medium to form a flavor microcapsule. The flavor microcapsules are prepared by suspension polymerization, and the capsule medium can be an emulsion.

[0037] Specifically, Figure 2 As shown, the microcapsule forming channel 14 is divided into a first sub-channel 141, a second sub-channel 142 and a third sub-channel 143 from bottom to top. The first sub-channel 141 contains flavor particles and an inert gas, the second sub-channel 142 contains a capsule medium, and the third sub-channel 143 is connected to the liquid storage chamber 111 and contains atomized liquid; wherein a gas-liquid interface is formed between the inert gas and the capsule medium, a liquid-oil interface is formed between the capsule medium and the atomized liquid, and the third sound field is used to drive the flavor particles to pass through the gas-liquid interface and the liquid-oil interface.

[0038] It should be understood that the capsule medium is insoluble in the atomized liquid and the inert gas, thereby forming a stable gas-liquid interface and liquid-oil interface in the microcapsule forming channel 14. When the sound field generating device 2 generates the third sound field, the flavor particles will be exerted with a third sound radiation force, which will overcome the Stokes resistance, shear lift and interfacial tension in the emulsion, so that the flavor particles can be driven and penetrate the gas-liquid interface and the liquid-oil interface, forming a flavor microcapsule in the third sub-channel 143, and realizing the encapsulation of the flavor particles. Preferably, the lengths of the first sub-channel 141, the second sub-channel 142 and the third sub-channel 143 increase in sequence, that is, the length of the first sub-channel 141 is less than the length of the second sub-channel 142, and the length of the second sub-channel 142 is less than the length of the third sub-channel 143, which is conducive to avoiding the first sub-channel 141 and the second sub-channel 142 from being connected to the liquid storage chamber 111, and preventing the flavor particles from moving into the liquid storage chamber 111 under the action of the first sound field.

[0039] In some embodiments, the third sound field generator is disposed below the first sub-channel 141, and the third sound field generator is used to generate ultrasonic waves propagating from the first sub-channel 141 to the third sub-channel 143 to form a third sound field. Specifically, the ultrasonic waves incident on the surface of the flavor particles will form scattering, thereby generating a third acoustic radiation force, and the force direction of the third acoustic radiation force is from bottom to top, so that the flavor particles move from the first sub-channel 141 to the third sub-channel 143 under the drive of the third acoustic radiation force. In other embodiments, a plurality of third sound field generators can be provided, and the plurality of third sound field generators are distributed around the microcapsule forming channel 14, and the combined force direction of the plurality of third acoustic radiation forces on the flavor particles is upward, ensuring that the flavor particles move upward, so that this arrangement can more accurately control the movement direction of the flavor particles, for example, the flavor particles can move to the upper left or upper right.

[0040] Furthermore, the capsule medium includes any one of liquid paraffin, liquid glucose, starch liquid, gelatin, polymethyl methacrylate and vinyl stearate, preferably liquid glucose, which has a higher coating rate and a better surface morphology of the flavor microcapsules formed by the flavor particles wrapped by liquid glucose.

[0041] See also Figure 1The microcapsule forming channel 14 and the connecting channel 12 are respectively arranged on both sides of the liquid storage chamber 111. The sound field generating device 2 further includes a fourth sound field generator, which is arranged on the side of the microcapsule forming channel 14 away from the liquid storage chamber 111. The fourth sound field generator is used to generate a fourth sound field that drives the flavor microcapsules in the microcapsule forming channel 14 to move toward the connecting channel 12. Specifically, the fourth sound field generator generates an ultrasonic wave that propagates from the microcapsule forming channel 14 toward the connecting channel 12. The ultrasonic wave incident on the surface of the flavor microcapsules in the third sub-channel 143 will be scattered, thereby generating a fourth acoustic radiation force. The force direction of the fourth acoustic radiation force is from the microcapsule forming channel 14 toward the liquid storage chamber 111, so that the flavor microcapsules flow from the third sub-channel 143 to the liquid storage chamber 111 under the drive of the second acoustic radiation force. The fourth acoustic radiation force is smaller than the surface tension of the flavor microcapsule capsule membrane, thereby preventing the flavor microcapsules from rupturing.

[0042] It should be noted that, in the embodiment of the present invention, the flavor microcapsules stored in the liquid storage chamber 111 all flow from the flavor microcapsules in the microcapsule forming channel 14, that is, the flavor particles are encapsulated in the microcapsule forming channel 14, the flavor microcapsules are stored in the liquid storage chamber 111, and the flavor particles are released in the connecting channel 12. For example, in one embodiment, the flavor particles in the first section sub-channel 141 are all encapsulated under the action of the third sound field, and then the flavor microcapsules in the third section sub-channel 143 all flow into the liquid storage chamber 111 under the action of the fourth sound field. When the atomized liquid or the flavor particles need to be supplemented, the atomized liquid can be supplemented through the third section sub-channel 143, and the flavor particles can be supplemented through the first section sub-channel 141, so that the atomized liquid and the flavor microcapsules are always stored in the liquid storage chamber 111.

[0043] In some embodiments, the atomizer further includes a detection device, which includes an optical signal emitting component, an optical signal receiving component, and a control board. The optical signal emitting component and the optical signal receiving component are both electrically connected to the control board, the optical signal emitting component is used to emit a detection optical signal into the liquid storage chamber 111, the optical signal receiving component is used to receive a reflected optical signal reflected by the flavor microcapsule, and the control board is used to calculate the flavor microcapsule content in the atomized liquid based on the detection optical signal and the reflected optical signal. According to actual needs, the optical signal emitting component can be an LED lamp, and the optical signal receiving component can be a light receiving element, such as a photodiode.

[0044] When the detection device detects that the content of flavor microcapsules in the atomized liquid is low, the control board controls the third and fourth sound field generators to work to replenish the content of flavor microcapsules in the liquid storage chamber 111, and the first and second sound field generators to work during the next puff, thereby increasing the content of flavor components in the aerosol inhaled. When the detection device detects that the content of flavor microcapsules in the atomized liquid is high, the control board controls the third and fourth sound field generators to stop working to prevent the preparation of flavor microcapsules.

[0045] See also Figure 1 The connection between the liquid storage chamber 111 and the communication channel 12 is provided with a diaphragm 4, which is configured to allow only the flavor microcapsules to pass through; wherein the diaphragm 4 may be a selective semipermeable membrane, such as a biofilm. The cross-section of the connection between the liquid storage chamber 111 and the communication channel 12 is as large as possible, that is, the area of ​​the diaphragm 4 is as large as possible, which is conducive to ensuring that the flavor microcapsules in the liquid storage chamber 111 flow into the communication channel 12; at the same time, the volume of the communication channel 12 is as small as possible, which is conducive to the flavor particles flowing into the air outlet channel 13 during suction.

[0046] See also Figure 1 The housing 1 is provided with an oil tank 11, and the oil tank 11 has a liquid storage chamber 111. The atomizing assembly 3 is arranged at the top of the oil tank 11, and the atomizing assembly 3 is connected to the bottom of the air outlet channel 13, so as to ensure that the aerosol generated by the atomizing liquid heated by the atomizing assembly 3 flows into the air outlet channel 13. Among them, the microcapsule forming channel 14 is arranged at the bottom of the oil tank 11, so as to prevent the atomized liquid stored in the third sub-channel 143 from flowing into the liquid storage chamber 111 after continuous inhalation for a period of time, thereby affecting the preparation of the flavor microcapsules.

[0047] In some embodiments, the atomization assembly 3 includes a support frame and an atomization core fixed to the support frame. The support frame is fixed to the outside of the oil tank 11, and the end of the atomization core away from the support is located in the air outlet channel 13. The atomization core is composed of an oil guide body and a heating body. The oil guide body can be made of porous materials such as porous ceramics, porous glass, fiber cotton, and oil guide ropes. The heating body is made of metal material. The oil guide body and the heating body can be integrated or split, or the atomization core can be a porous metal body. Among them, one end of the oil guide body extends to the bottom of the oil tank 11 so that the oil guide body can continuously introduce the atomized liquid.

[0048] 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.
