[0036] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] On the one hand, an embodiment of the present application discloses an atomizer, including a power supply component and an atomization component. The power supply component is electrically connected to the atomization component. By applying a voltage to the atomization component, the atomization component can be made to oscillate, thereby causing resonance with the atomized liquid in the atomization component to achieve atomization.

[0038] Specifically, the power supply assembly includes an energy storage component and an electrode assembly, and the electrode assembly is used to connect the energy storage component and the atomization component to form a conductive loop.

[0039] The energy storage component is a device that stores electrical energy and can release electrical energy to enable the atomization component to form a conductive loop. As one implementation, the energy storage component can be a battery.

[0040] Another aspect of the present application discloses an atomization assembly, see Figures 1 to 4 , including an atomizing sheet 110 , a conductive substrate 120 and a delivery pipeline 130 .

[0041] Specifically, the atomizing sheet 110 is located on one of the surfaces of the conductive substrate 120, and the atomizing sheet 110 is fixedly connected to the conductive substrate 120; the delivery pipeline 130 is arranged on the side of the conductive substrate 120 away from the atomizing sheet 110, and the delivery pipeline 130 has at least one delivery channel, and the extension trajectory of each delivery channel is a spiral line, one end of the delivery channel is connected to the output part 140, and the other end of the delivery channel is connected to the liquid inlet part 150 and the air inlet part 160, and the angle φ between the liquid inlet part 150 and the air inlet part 160 along the delivery direction of the delivery channel is an acute angle. Among them, the atomizing sheet 110 forms an atomizing area corresponding to the overlapping position with the conductive substrate 120, and a Taylor flow is formed in the delivery channel, and the liquid in the Taylor flow is atomized in the atomizing area.

[0042] In the aforementioned embodiment, each delivery channel is fixedly connected to a side of the conductive substrate 120 away from the atomizing sheet 110. The vibration generated after the atomizing sheet 110 is energized can be transmitted to the liquid in the delivery channel to cause the liquid to resonate and achieve atomization. The delivery direction of the delivery channel refers to the delivery direction of the fluid in the delivery channel. For the liquid inlet 150, the delivery direction is the flow direction of the fluid in the liquid inlet 150; for the air inlet 160, the delivery direction is the flow direction of the fluid in the air inlet 160, and the angle φ refers to the angle between the flow direction of the fluid in the liquid inlet 150 and the flow direction of the fluid in the air inlet 160.

[0043] It is worth understanding that Taylor flow is also called gas-liquid segmented flow or plunger flow, that is, Taylor flow is a fluid in which gas and liquid are alternately distributed. In other words, the gas in the Taylor flow occupies a certain space, which provides space and conditions for the liquid in the Taylor flow to be atomized through resonance in the delivery channel. When the atomizer sheet 110 is turned on, the liquid segment in the Taylor flow in the delivery channel resonates and atomizes in the atomization area, and the atomized aerosol naturally diffuses to the position of the gas segment. The gas in the gas segment drives the aerosol to be transported to the output part 140 and ejected from the output part 140. Among them, the liquid segment is the liquid part in the Taylor flow; the gas segment is the gas part in the Taylor flow.

[0044] In the aforementioned embodiment, the conductive substrate 120 is electrically connected to one end of the atomizing sheet 110, and the other end of the atomizing sheet 110 is connected to another electrode. By applying a voltage to the atomizing sheet 110 through the conductive substrate 120 and the other electrode, the atomizing sheet 110 can be made to oscillate, so that the liquid segment of the Taylor flow in the delivery pipe 130 produces a cavitation reaction under the vibration to achieve atomization; the atomized atomized liquid can be sprayed out from the output portion 140.

[0045] In the atomization assembly and atomizer of the present application, a delivery channel is provided on the conductive substrate 120 to deliver the atomized liquid. The extension trajectory of the delivery channel is in a spiral shape and the inner diameters of each cross section in the channel are equal, that is, each area in the delivery channel can smoothly transition, so that the flow resistance of the fluid in the delivery channel is greatly reduced, and the delivery resistance of the atomized liquid is reduced. At the same time, compared with the traditional liquid storage tank, the delivery channel of the present application is coiled on one of the surfaces of the conductive substrate 120, which occupies a small space, and the angle between the liquid inlet and the air inlet along the delivery direction of the delivery channel is set at an acute angle, which can reduce the resistance to liquid supply, and at the same time help to reduce the liquid reflux in the delivery pipeline, which is conducive to improving the accuracy of the dosage control of the atomized liquid; and because the delivery channel is coiled on one of the surfaces of the conductive substrate 120, the fluid stroke is extended, which provides conditions for effective dosage control and liquid supply, and helps to achieve the control of the dosage of the atomized liquid. In addition, the delivery channel can store more fluid, and an atomization area is formed in the atomization sheet 110. The delivery channel located in the atomization area forms resonance, so that the liquid segment in the delivery channel is atomized and then output from the output part 140, which helps to improve the atomization efficiency.

[0046] In practical applications, gas and liquid alternately enter the delivery channel from the liquid inlet 150 and the gas inlet 160 respectively, and form Taylor flow.

[0047] In some embodiments of the present application, the liquid segment length of the Taylor flow can be controlled by adjusting the liquid and / or gas intake time, which helps to achieve dosage control while providing effective liquid supply conditions.

[0048] In some embodiments of the present application, the atomization area is the area where the atomization sheet 110 overlaps with the conductive substrate 120, and the output portion 140 is disposed in the central area. The Taylor flows delivered from each delivery channel converge at the output portion 140, and the Taylor flows are driven by the vibration of the atomization sheet 110 during the delivery process to produce a cavitation effect, thereby achieving atomization.

[0049] In some embodiments of the present application, the electrode assembly includes a positive electrode and a negative electrode, one of which is electrically connected to the conductive substrate 120 of the atomization assembly, and the other is electrically connected to the other side of the piezoelectric ceramic away from the conductive substrate 120.

[0050] In the embodiment of the present application, at the junction of the delivery channel and the liquid inlet 150, the tangent of the delivery channel is set at an angle with the liquid inlet. When the liquid is transported from the liquid inlet 150 to the delivery channel, the liquid needs to turn and pass through the junction of the liquid inlet 150 and the delivery channel before it can flow along the delivery channel. In this way, when liquid and gas are alternately transported into the delivery channel through the liquid inlet 150 and the gas inlet 160, it helps to form a Taylor flow, which is beneficial for fully mixing the liquid and the liquid, so as to better produce the cavitation effect and improve the atomization effect.

[0051] In some embodiments of the present application, the spiral is an equidistant spiral, that is, an Archimedean spiral. Setting the extension trajectory of the delivery channel as an equidistant spiral helps to keep the flow resistance of the fluid at various positions in the delivery channel stable, which helps to improve the accuracy of dosage control.

[0052] It should be noted that in some other embodiments, the spiral line can also be a non-equidistant spiral line, for example, a non-equidistant gradually opening spiral line. It should be understood that the spiral line described in the present application is a two-dimensional spiral line, and the projection of the transport channel along the direction perpendicular to the conductive substrate 120 and the shape presented on the conductive substrate 120 is a spiral line.

[0053] In some embodiments of the present application, the conductive substrate 120 is made of metal material. The metal substrate has a conductive function and can be used as one of the electrodes of the atomizer 110. In practical applications, the metal material can be copper, silver, nickel, aluminum, and other materials with conductive properties.

[0054] In some embodiments of the present application, the atomizer 110 is made of piezoelectric ceramics.

[0055] In some embodiments of the present application, the material of the atomizer 110 is specifically PZT piezoelectric ceramics. PZT piezoelectric ceramics have a piezoelectric effect, and can generate vibrations by applying voltage to the PZT piezoelectric ceramics. In this way, the atomizer 110 can drive the delivery pipe 130 to vibrate, so that the liquid in the delivery channel resonates, thereby achieving atomization.

[0056] In some embodiments of the present application, the output portion 140 may be a component having an output port; the air inlet portion 160 may be a component having an air inlet channel; and the liquid inlet portion 150 may be a component having a liquid inlet channel. In addition, the output portion 140, the air inlet portion 160 and the liquid inlet portion 150 are all part of the delivery pipeline 130.

[0057] In some embodiments of the present application, see Figure 1 One end of the delivery channel connected to the output part 140 is marked as the first end 131, and the other end is the second end 132, and the second end 132 is used to connect the liquid inlet part 150 and the air inlet part 160. The output part 140 can be connected to the atomization channel connected to the suction nozzle, so that the aerosol formed after the atomized liquid is atomized can flow to the suction nozzle through the atomization channel, and it is convenient for the user to inhale.

[0058] In some other embodiments, the first end 131 of the delivery channel may also be directly connected to the atomization channel.

[0059] In some embodiments of the present application, see Figure 1The delivery pipeline 130 includes a plurality of delivery channels, one end of each delivery channel is connected to the output part 140, and the plurality of delivery channels are arranged in a circular array with the output part 140 as the reference. Specifically, the plurality of delivery channels are arranged in an array with the output part 140 as the reference, and are all coiled on the conductive substrate 120, so that the fluid in each channel can be evenly distributed on the conductive substrate 120. The lengths of the delivery channels are equal, and the flow resistance of the Taylor flow at the same position in each delivery channel is also equal. In this way, by controlling the dosage of the gas and liquid at the air inlet 160 and the liquid inlet 150, the dosage control of the atomization component and the control of the liquid supply can be achieved.

[0060] In some embodiments of the present application, see Figure 1 The delivery pipeline 130 includes four delivery channels, and the four delivery channels are arranged in a circular array around the output part 140. As shown in the figure, the first ends 131 of the four delivery channels are arranged at intervals of 90 degrees on the periphery of the output part 140, so that the atomized atomized liquid can be evenly delivered to the output part 140 and sprayed out from the output part 140. It should be noted that the length and pipeline size of each delivery channel are equal, that is, the fluid travels the same distance in each delivery channel. In this way, it is convenient to control and adjust the dosage of each delivery channel at the same time.

[0061] In some embodiments of the present application, see Figure 4 , the tangent line at the junction of the delivery channel and the liquid inlet 150 is a, the axis of the liquid inlet 150 is b, and the angle between the tangent line a and the axis b of the liquid inlet 150 is θ, which satisfies: θ is less than 90°. In this way, the backflow of the liquid at the junction of the liquid inlet 150 and the delivery channel can be reduced, which is conducive to ensuring smooth liquid supply and also helps to improve the accuracy of dosage control.

[0062] In some embodiments of the present application, see Figures 1 to 3 The gas inlet 160 is connected to the liquid inlet 150. Specifically, when the gas is delivered to the gas inlet 160, the gas can separate the liquid in the liquid inlet 150, which is helpful to form the Taylor flow.

[0063] Further, see Figure 4 As shown, there is an angle φ between the air inlet 160 and the liquid inlet 150, which satisfies: φ<90°. Specifically, the tangent at the end of the air inlet 160 is c, and the angle φ between the tangent c and the axis b is the angle between the air inlet 160 and the liquid inlet 150. In this way, after the gas enters the liquid inlet 150 from the air inlet 160, it can flow along the liquid in the liquid inlet 150 to the delivery channel, reducing the impact and collision between the gas and the liquid, helping to form a Taylor flow, and providing space for the atomization of the liquid in the delivery channel, thereby helping to improve the atomization effect.

[0064] Furthermore, the angle between the delivery channel and the liquid inlet 150 is θ, which satisfies: φ<θ. In this way, it is avoided that the flow direction of the gas in the gas inlet 160 is completely opposite to the flow direction in the delivery channel (that is, the angle between the two flow directions is 180°), which can improve the smoothness of the flow of the gas in the delivery channel and help improve the accuracy of dosage control.

[0065] In some embodiments of the present application, see Figures 1 to 3 , the air inlet 160 is arc-shaped. Specifically, one end of the air inlet 160 is connected to the middle of the liquid inlet 150, and the other end is used to connect to the gas transmission equipment. The air inlet 160 is arc-shaped, which increases the angle between the air inlet 160 and the liquid inlet 150 at the connection point. In this way, when the gas is transported to the delivery channel, the gas can be more easily gathered into a section, which is helpful to form a Taylor flow, wherein the angle is an acute angle, so that the gas can smoothly enter the liquid inlet 150 and flow to the delivery channel, and will not rush to the liquid inlet end of the liquid inlet 150, thereby improving the accuracy of quantitative liquid supply.

[0066] It should be understood that the shape of the air inlet 160 can be selected into shapes with different curvatures according to actual needs, and the arc shape includes but is not limited to a circular arc shape or an elliptical arc shape.

[0067] It should be noted that in some other embodiments, the positions of the air inlet 16 and the liquid inlet 150 can be interchanged, and the two can also be arranged at an acute angle after being interchanged. In this way, when one of the liquid inlet 150 and the air inlet 160 inputs fluid, the fluid will not flow from the other to a direction away from the delivery pipeline, thereby facilitating the improvement of the accuracy of dosage control.

[0068] In some embodiments of the present application, the delivery pipe 130 is at least partially made of a transparent material, so that the formation and distribution of the Taylor flow in the delivery channel can be easily observed.

[0069] As one embodiment, the material of the delivery channel 130 is PDMS. PDMS is specifically polydimethylsiloxane, which is a high molecular weight organic silicon compound. PDMS is a transparent material, which is convenient for observing the flow of the fluid in the delivery channel. Figure 5 shown.

[0070] Figure 5 In FIG. 1 , only the flow distribution of gas and liquid in one delivery channel is shown. As can be seen from the figure, gas and liquid are alternately distributed in the delivery channel. When the atomizing sheet 110 drives the delivery channel to resonate, it is more conducive to liquid atomization.

[0071] In some embodiments of the present application, the atomizer sheet 110 may be partially embedded in the conductive substrate 120 to enhance the resonance effect, thereby helping to improve the atomization effect.

[0072] In some embodiments of the present application, the delivery pipe 130 is at least partially embedded in the conductive substrate 120 to enhance the resonance effect, thereby helping to improve the atomization effect. It should be noted that when the delivery pipe 130 is made of a transparent material, the transparent portion of the delivery pipe 130 is exposed or protrudes from the conductive substrate 120.

[0073] In some embodiments of the present application, the atomizing sheet 110 is deposited and bonded to the conductive substrate 120 by a photolithography process. Furthermore, the delivery pipe 130 is also deposited and bonded to the conductive substrate 120 by a photolithography process. In other words, the atomizing sheet 110 and the delivery pipe 130 can be tightly connected to the conductive substrate 120 respectively, which increases the stability of the mutual connection and reduces the probability of looseness between the atomizing sheet 110 and the conductive substrate 120 or the delivery pipe 130 and the conductive substrate 120. In this way, it can be ensured that the vibration of the atomizing sheet 110 can be transmitted to the delivery pipe 130, which is conducive to ensuring that the fluid in the delivery pipe 130 produces a cavitation effect and achieves atomization.

[0074] In some other embodiments, the atomizing sheet 110 and the delivery pipe 130 may also be fixedly connected to the conductive substrate 120 by bonding.

[0075] The atomizer of some embodiments of the present application also includes a liquid supply control system, which includes: a control device 210, an air pumping device 220, a liquid supply device 230 and an atomization assembly, the air pumping device 220 is connected to the air inlet part 160, the liquid supply device 230 is connected to the liquid inlet part 150, and the control device 210 is configured to alternately control the liquid supply device 230 to supply liquid to the liquid inlet part 150 and control the air pumping device 220 to supply air to the air inlet part 160, so as to control the amount of liquid supplied to the atomization assembly.

[0076] It is worth to understand that the air pump device 220, the liquid supply device 230 and the atomization component can also be combined into an integral structure and integrated into an atomizer having the atomization component, which is not limited here.

[0077] In one embodiment, see Figure 6 The air pumping device 220 , the liquid supply device 230 and the atomizing assembly are independent devices that are separated from each other, and the control device 210 is configured to alternately control the liquid supply device 230 to supply liquid to the liquid inlet 150 and control the air pumping device 220 to supply air to the air inlet 160 .

[0078] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
