Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomizing core, atomizer, and atomizing device. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by the dispersion and suspension of solid or liquid particles in a gaseous medium. Electronic atomization devices mainly form aerosols by heating aerosols to generate a matrix (such as oils, leaves, pastes, etc.).

[0003] The atomizer is a crucial component of electronic atomization devices, used to guide the aerosol-generating matrix to a designated location for atomization. With technological advancements, the liquid guiding element (atomizing coil) in atomizers has evolved from synthetic fibers and natural fibers to today's porous ceramic materials. This has resolved the instability issues in the atomization process, and the flavor profile has become more refined due to adjustments in the ceramic's pore size.

[0004] However, porous ceramics are high-temperature sintered solids of ceramic powder, with fixed pore sizes, making it impossible to further refine the atomized particles. Larger-diameter atomized particles may affect the human body's absorption efficiency of aerosols. Furthermore, the metal films printed with metal paste or sputtered by magnetron sputtering used in porous ceramics, when heated under electric current, may have ceramic particles falling into the aerosol. Additionally, the electrochemical reactions of metals in the solution, producing metal salts, can also affect the safety of the aerosol, thus impacting the absorption efficiency and safety of the atomizer.

[0019] In one embodiment, the refined layer has a first air guide hole that communicates with the atomizing zone and the exhaust hole.

[0020] In one embodiment, the atomizing core further includes a trapping layer disposed between the liquid inlet layer and the atomizing layer, the trapping layer being used to trap liquid particles carried in the aerosol flowing from the atomizing zone to the exhaust port.

[0021] In one embodiment, the capturing layer has a capturing area that is disposed intersecting with the aerosol flow direction of the atomizing area toward the exhaust port.

[0022] In one embodiment, the capture zone has multiple capture channels, and the multiple capture channels are provided with a second air guide hole and a third air guide hole. The second air guide hole is connected to the exhaust hole, and the third air guide hole is connected to the atomization zone.

This allows the atomizing core provided in this application to refine atomized particles with larger diameters without the presence of metal impurities or ceramic particles that could affect aerosol safety. Consequently, the atomizer's absorption efficiency is improved, and its safety is enhanced. Attached Figure Description

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0051] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0053] As described in the background section, the liquid guiding element in atomizers has evolved from artificial fibers and natural fiber heating elements to porous ceramic heating elements, solving the problem of instability in the atomization process. The flavor is also more delicate due to the adjustment of ceramic pores. At the same time, the durability of ceramics greatly increases the lifespan of the atomizer, and mass production allows for batch sintering, making it more suitable for large-scale production.

[0054] However, with the development of atomization technology, users have raised higher requirements for the liquid guiding elements in current atomizers:

[0055] 1) The preparation of porous ceramics requires specialized sintering equipment and the process is complex. Can you provide liquid-conducting elements that are simple to manufacture and low in cost?

[0056] 2) Porous ceramics are high-temperature sintered solids of ceramic powder. The size and porosity of their internal pores are fixed. During use, it is impossible to further refine the atomized particles. Larger diameter atomized particles may affect the human body's absorption efficiency of aerosols, resulting in a worse user experience.

[0057] 3) The metal film layer printed with metal paste or sputtered by magnetron sputtering in porous ceramics may fall into the aerosol when heated under the drive of current. The metal salts produced by the electrochemical reaction of metal in solution may also affect the safety of the aerosol, thus affecting the safety of the atomizer.

[0058] Based on the above considerations, see [reference] Figure 1 and Figure 2 Through research, the applicant has discovered an atomizing core 10, which is used in atomizers as a liquid guiding element for aerosol generation matrix, and can also be used in other structures as a liquid guiding element. This application takes an atomizer as an example.

[0059] The atomizing core 10 provided in this application has a simple structure and can refine the aerosol-generating matrix particles (i.e., reduce the particle diameter) during the liquid guiding process. Specifically, see [link to relevant documentation]. Figure 1The atomizing core 10 includes an air inlet layer 16, an atomizing layer 15, and a liquid inlet layer 11 stacked sequentially. The air inlet layer 16 has an air inlet hole 161, and the liquid inlet layer 11 has a liquid inlet hole f and an exhaust hole 112. The atomizing layer 15, which is layered between the two, includes a capillary drainage structure 151 and an atomizing zone 154. The air inlet hole 161 and the exhaust hole 112 are connected to the atomizing zone 154. The capillary drainage structure 151 is connected to the liquid inlet hole f and is used to guide the atomizing medium flowing out of the liquid inlet hole f to the atomizing zone 154 to generate an aerosol.

[0060] During the actual flow process of the atomizing core 10, the flow path of the atomizing medium (i.e., the aerosol generation matrix) is as follows: it enters the interior of the atomizing core 10 from the liquid inlet hole f, and is refined and guided to the atomizing zone 154 by the capillary action of the capillary drainage structure 151. The flow path of the aerosol is as follows: it is generated on the atomizing zone 154, carried away by the airflow entering the atomizing core 10 through the air inlet hole 161, and discharged from the atomizing core 10 through the exhaust hole 112 for the user to inhale.

[0061] Thus, this application forms a composite liquid-guiding structure through the stacked air inlet layer 16, atomizing layer 15, and liquid inlet layer 11. The liquid inlet layer 11 facilitates the introduction of the atomizing medium, while the exhaust holes 112 on the atomizing layer 15 and liquid inlet layer 11 facilitate the discharge of the aerosol. Furthermore, the capillary drainage structure 151 of the atomizing layer 15 refines the particles of the aerosol-generating matrix, reducing their diameter before atomization in the atomization zone 154. This allows the atomizing core 10 provided in this application to further refine the atomizing medium flowing into the liquid inlet hole f, preventing the presence of impurities such as metal or ceramic particles that could affect aerosol safety, ensuring the purity and safety of the aerosol, and improving the absorption efficiency and safety of the atomizer.

[0062] Understandably, this application avoids traditional porous ceramics and adopts a relatively simple layered stacking structure to form the atomizing core 10. The manufacturing process of each layer (air inlet layer 16, liquid inlet layer 11 and atomizing layer 15) is relatively simple, thereby reducing the production cost.

[0063] Furthermore, in some of these embodiments, see [reference]. Figures 1 to 2 The capillary drainage structure 151 includes multiple capillary microchannels 1511, each capillary microchannel 1511 is connected to the liquid inlet hole f and extends to the atomization zone 154.

[0064] Each capillary microchannel 1511 has a very small channel size, and a directional capillary force is formed inside it. After the atomizing medium from the liquid inlet hole f flows into one of the capillary microchannels 1511, it can actively flow along the extension direction of the capillary microchannel 1511, thereby actively guiding the atomizing medium introduced by the liquid inlet hole f to the atomization zone 154, realizing the directional flow of the atomizing medium.

[0065] Understandably, the specific number and size of the capillary microchannels 1511 in the capillary drainage structure 151 are determined according to actual usage requirements, and this application does not impose any limitations on them. For example, they can be configured as dendritic dispersions to allow the atomizing medium introduced through the liquid guiding holes to flow divergently and be further refined.

[0066] In one embodiment, to ensure uniform liquid supply to the capillary microchannel 1511 and unidirectional entry of the atomizing medium, i.e., to prevent the atomizing medium from flowing back from the atomizing zone 154 into the capillary drainage structure 151, see [reference needed]. Figure 2 Each capillary microchannel 1511 is equipped with a one-way valve 157. Similar to the Tesla one-way valve structure, it ensures that the atomizing medium will not flow back into the capillary microchannel 1511 due to drastic volume expansion, thus preventing blockage of the capillary microchannel 1511 or changes in the supply liquid volume.

[0067] The diameter of the capillary microchannel 1511 is above 10 μm, preferably 30-80 μm at its finest point. Furthermore, based on current advancements in microfluidic technology, a specially designed one-way Tesla valve structure can further reduce the risk of leakage and the problem of unstable atomization during the atomization process.

[0068] In one embodiment, see [reference] Figure 1 The liquid inlet hole f includes a first liquid inlet hole 111 and a second liquid inlet hole 113. The capillary drainage structure 151 is used to mix the different atomizing media flowing out of the first liquid inlet hole 111 and the second liquid inlet hole 113 and then guide them to the atomizing zone 154.

[0069] Specifically, the capillary microchannel 1511 is connected to the first liquid inlet hole 111 and the second liquid inlet hole 113, and provides capillary force to attract the atomizing medium flowing out of the first liquid inlet hole 111 and the second liquid inlet hole 113 connected to it, and actively mixes it in its own channel to form a mixed medium, which is then guided to the atomization zone 154 to realize the directional flow and active mixing of different atomizing media.

[0070] The atomizing core 10 of this application, through the setting of multiple liquid inlet holes f (i.e., the first liquid inlet hole 111 and the second liquid inlet hole 113), can realize the active mixing of at least two different atomizing media during the liquid guiding process of the atomizing core 10, so that the atomizing core 10 can actively mix different atomizing media at any time during use to meet the different taste needs of users and realize functional diversification.

[0071] Because of the significant volume change during liquid-gas conversion, the air intake layer 16, located on the side of the atomizing layer 15 opposite to the liquid inlet layer 11, allows the gas entering through the air inlet 161 to be used to control the internal balance of the atomizing core 10. Furthermore, the longer flow path within the atomizing core 10 also better prevents leakage. In other embodiments, the air intake layer 16 can be integrated into other structural components.

[0072] In one embodiment, see [reference] Figure 1 The liquid inlet layer 11 may have multiple vent holes 112, which are arranged in a matrix on the liquid inlet layer 11 to divert the aerosol generated by atomization in the atomization zone 154 to the multiple vent holes 112 for discharge. The diameter of a single air inlet 161 can be 10-1000 μm, and the number of air inlets 161 can be 10-10000, arranged in different two-dimensional shapes, such as circles, squares, hexagons, etc. Preferably, the diameter of a single air inlet 161 is 30-200 μm, and the number of pressure air inlets 161 is 50-5000.

[0073] In one embodiment, see [reference] Figures 1 to 2 The atomizing layer 15 includes a first liquid outlet 155 and a second liquid outlet 156. The first liquid outlet 155 is connected to the first liquid inlet 111, and the second liquid outlet 156 is connected to the second liquid inlet 113. The capillary drainage structure 151 is used to mix the different atomizing media flowing out of the first liquid outlet 155 and the second liquid outlet 156 and then guide them to the atomizing zone 154.

[0074] The first liquid outlet 155 and the first liquid inlet 111 are connected to form a liquid guiding channel for one atomizing medium. The second liquid outlet 156 and the second liquid inlet 113 are connected to form a liquid guiding channel for another atomizing medium. After the two atomizing media enter the interior of the atomizing core 10 from the liquid inlet layer 11, they finally flow into the capillary drainage structure 151 of the atomizing layer 15 from the first liquid outlet 155 and the second liquid outlet 156 to achieve directional flow and active mixing.

[0075] Understandably, the liquid inlet port f can be set to multiple or one. When the liquid inlet port f is set to one, if a mixed medium formed by mixing multiple different atomizing media is required for atomization, it can be mixed outside the atomizing core 10 and then introduced into the atomizing core 10 through the liquid inlet port f.

[0076] In one embodiment, in order to improve the atomization efficiency, the capillary microchannels 1511 can also be provided in multiple layers in the stacking direction of the liquid inlet layer 11 and the atomizing layer 15, and the atomizing medium can enter through the multiple layers of capillary microchannels 1511.

[0077] Specifically, after passing through the first layer of capillary microchannels 1511, the atomizing medium enters the middle layer of capillary microchannels 1511. Before the atomizing medium adsorbed in this layer of capillary microchannels enters the last layer of capillary microchannels 1511, this location allows for the retention of the liquid medium through capillary siphon effect and the mixing of various atomizing media with different physical properties (introduced through different liquid guide holes). Furthermore, throughout the entire usage process, different atomizing media can be actively mixed at any time to form different mixed media to meet the user's different taste preferences, thus realizing the functional diversification of the atomizing core 10.

[0078] To maintain the atomizing medium, it is necessary to utilize the surface tension of the liquid in the capillary microchannel 1511 and the large area of ​​the capillary microchannel 1511. Therefore, it is necessary to disperse the incoming atomizing medium. The dispersion can be unidirectional or multidirectional radial, but it is necessary to ensure that the mixed medium or atomizing medium after the two atomizing media are mixed enters the last layer of capillary microchannel 1511 and is guided to the atomizing zone 154.

[0079] Furthermore, the microchannel 1511 can be fabricated using dry microchannel fabrication processes such as plasma etching, or by methods such as HF (hydrogen fluoride) wet etching, laser etching, or machining. Due to the small cross-sectional area of ​​the microchannel, machining methods are not recommended.

[0080] In one embodiment, see [reference] Figure 1 and Figure 3 The atomizing core 10 also includes a refining layer 12, which is disposed between the liquid inlet layer 11 and the atomizing layer 15. The refining layer 12 has at least one refining region 121, which is connected to the first liquid inlet hole 111 or the second liquid inlet hole 113 to refine the atomizing medium flowing out therein.

[0081] The refining zone 121 breaks down large atomizing media particles into smaller particles, which then flow to the atomizing layer 15 for atomization or mixing with another atomizing medium, thereby obtaining mixed medium particles with smaller atomization particle size, so as to improve the absorption efficiency of the human body and reduce the frequency of atomizer use.

[0082] In one optional embodiment, at least one refining region 121 includes a plurality of through-holes 1211. The plurality of first refining holes 1211 are used to refine the particle size of the atomizing medium flowing out of the first liquid inlet hole 111 or the second liquid inlet hole 113, thereby achieving a refinement of the liquid phase diameter of the atomizing medium from large to small. For example, when the refining layer 12 is directly disposed downstream of the liquid inlet layer 11 to refine the atomizing medium flowing in through the first liquid inlet hole 111, the flow cross-sectional area of ​​the first refining hole 1211 should be smaller than the flow cross-sectional area of ​​the first liquid inlet hole 111. By controlling the flow cross-sectional area, the liquid phase particles are broken up, thereby achieving a reduction in particle size, i.e., refining.

[0083] Understandably, if there are other structures between the refining layer 12 and the atomizing layer 15, then the downstream structures after the flow through the refining region 121 should all have corresponding refining structures to ensure that the particle size of the atomized medium refined by the refining layer 12 can be maintained in the refined state.

[0084] In one embodiment, the refining layer 12 has a first liquid guiding hole 122 and a second liquid guiding hole 124. The first liquid guiding hole 122 is connected to the first liquid inlet hole 111, and the second liquid guiding hole 124 is connected to the second liquid inlet hole 113. At least one refining region 121 is connected to the first liquid guiding hole 122 or the second liquid guiding hole 124 to refine the atomizing medium flowing out therefrom.

[0085] Understandably, if it is necessary to refine the atomized medium flowing out of the first liquid inlet hole 111 or the second liquid inlet hole 113, then a flow guiding channel needs to be set on the refining layer 12 to guide the atomized medium flowing out of the first liquid inlet hole 111 or the second liquid inlet hole 113 to the refining area 121 and refine it through a plurality of first refining holes 1211 in the refining area 121.

[0086] Specifically, at least one refined region 121 further includes a plurality of connecting grooves 1212, one end of each connecting groove 1212 being connected to a first liquid guiding hole 122 or a second liquid guiding hole 124, and a plurality of first refined holes 1211 being provided through the other end of each connecting groove 1212.

[0087] Multiple connecting grooves 1212 are not connected to the refining layer 12. The first end of each connecting groove 1212 is connected to the inlet (i.e., the first liquid guide hole 122 or the second liquid guide hole 124) of the atomizing medium that needs to be refined, and multiple first refining holes 1211 are opened through the end.

[0088] For example, when it is necessary to refine the atomizing medium flowing into the first inlet hole 111, the atomizing medium flowing out of the first inlet hole 111 enters the first guide hole 122 and moves from the beginning to the end along the extension direction of the connecting channel 1212. After being diverted by multiple connecting channels 1212, the atomizing medium flows to the end of the multiple connecting channels 1212 and leaves this refining area 121 through multiple first refining holes 1211 at the end of the connecting channel 1212, thus completing the refining. Therefore, the diversion by the connecting channel 1212 and the refining by the first refining holes 1211 achieve a dual effect, ensuring that the atomizing medium can be broken into sufficiently small particles.

[0089] Understandably, the diameter of the first refining hole 1211 and the size and number of the connecting grooves 1212 can be adjusted arbitrarily according to the usage requirements in practical applications, and this application does not limit them here.

[0090] Furthermore, after the addition of the refining layer 12, the aerosol generated from the atomization zone 154 needs to pass through the refining layer 12 before flowing to the exhaust port 112. In order to ensure the normal flow of the aerosol, the refining layer 12 has a first air guide hole 123. The first air guide hole 123 is connected to the atomization zone 154 and the exhaust port 112 to form an air guide channel for the aerosol to flow.

[0091] Understandably, the airflow direction in the air delivery channel of the aerosol is opposite to the flow direction of the atomizing medium in the liquid delivery channel. The atomizing core 10 can not only provide liquid delivery capability, but also provide reverse air delivery capability after the atomizer generates aerosol mist, so as to meet the atomizer's usage requirements.

[0092] In one embodiment, see [reference] Figure 4 The atomizing core 10 also includes a trapping layer 13, which is located between the liquid inlet layer 11 and the atomizing layer 15 to trap liquid particles carried in the aerosol flowing from the atomizing zone 154 to the exhaust port 112, thereby preventing the aerosol from containing incompletely atomized liquid particles, which would affect the taste of the atomizer.

[0093] Specifically, the capture layer 13 has a capture zone 131, which is arranged to intersect with the aerosol flow direction from the atomization zone 154 to the exhaust port 112. When the aerosol flows to the capture zone 131, the large liquid particles carried in the aerosol are collected in the capture zone 131 to further refine the particle size of the inhaled aerosol and improve the absorption efficiency.

[0094] In some embodiments, the capture zone 131 can be designed as an in-situ three-dimensional microchannel structure or a triangular groove-shaped capture structure. In the multi-layer atomizing core 10 design, the aerosol is discharged along the stacking direction of the atomizing core 10. The capture zone 131 is set along the direction intersecting with the airflow direction, so that large liquid particles carried in the aerosol can move along the plane direction intersecting with the aerosol flow direction when passing through the capture zone 131, while the airflow continues to be discharged along the stacking direction, thereby enabling the capture zone 131 to have the function of preventing large unstable liquid particles from being discharged.

[0095] Furthermore, the capture zone 131 has multiple capture channels 136, and each capture channel 136 is provided with a second air guide hole 134 and a third air guide hole 135. The second air guide hole 134 is opposite to and connected to the exhaust hole 112, and the third air guide hole 135 is opposite to and connected to the atomization zone 154. The aerosol generated on the atomization zone 154 flows from the third air guide hole 135 to the second air guide hole 134, and finally flows to the exhaust hole 112.

[0096] Meanwhile, as the aerosol flows from the third air guide hole 135 to the second air guide hole 134, taking advantage of the characteristic that the speed of large liquid particles is less than the speed of aerosol mist, due to the law of conservation of momentum, the flow rate of aerosol liquid entering the capture channel 136 will further slow down, while the gas continues to flow at high speed. Therefore, the water droplet capture area 131 has the function of capturing large aerosol particles, so that the liquid particles are captured by the capture channel 136.

[0097] The capture zone 131 can also use an etched micro-capture device, through which small-molecule aerosol mist can pass. When large liquid particles pass by, droplets are captured. The specific capture method is not limited in this application.

[0098] Understandably, the capture layer 13 may have one or more layers and may be disposed between the liquid inlet layer 11 and the atomizing layer 15, or between the refining layer 12 and the atomizing layer 15, or disposed inside the liquid inlet layer 11, to capture liquid particles before the aerosol flows out from the exhaust port 112.

[0099] In one embodiment, the trapping layer 13 is configured to not only trap liquid particles but also to avoid affecting the flow of the atomizing medium. The trapping layer 13 further includes a third liquid guiding hole 132 and a fourth liquid guiding hole 133. The third liquid guiding hole 132 is connected to the first liquid inlet hole 111, and the fourth liquid guiding hole 133 is connected to the second liquid inlet hole 113, so as to ensure that the atomizing medium can flow from the liquid inlet layer 11 to the atomizing layer 15 through the third liquid guiding hole 132 and the fourth liquid guiding hole 133.

[0100] Specifically, if the capturing layer 13 is disposed between the refining layer 12 and the atomizing layer 15, the diameter of one or both of the third liquid guiding hole 132 or the fourth liquid guiding hole 133 that is opposite to the refining region 121 on the refining layer 12 must be less than or equal to the diameter of the first refining hole 1211, so as to ensure that the particle size of the atomized medium after being refined by the refined region 121 can be maintained in the refined state.

[0101] In one embodiment, see [reference] Figure 5 The atomizing core 10 is also provided with a liquid guiding layer 14, which is located between the capture layer 13 and the atomizing layer 15. The liquid guiding layer 14 is used to guide the atomizing medium flowing out from the capture layer 13 to the atomizing layer 15, and also to guide the aerosol mist generated on the side of the atomizing layer 15 to the capture layer 13.

[0102] In one embodiment, the liquid guiding layer 14 further includes a fifth liquid guiding hole 141 and a sixth liquid guiding hole 143. The fifth liquid guiding hole 141 is connected to the first liquid inlet hole 111 and the fifth liquid guiding hole 141 is connected to the second liquid inlet hole 113, so as to ensure that the atomizing medium can flow from the liquid inlet layer 11 to the atomizing layer 15 through the fifth liquid guiding hole 141 and the sixth liquid guiding hole 143.

[0103] Furthermore, the liquid guiding layer 14 also has a fourth air guiding hole 142 to ensure that the aerosol generated from the atomization zone 154 can flow through the fourth air guiding hole 142 to the exhaust hole 112.

[0104] Furthermore, after the atomizing medium flows downward to the atomizing zone 154 and is atomized, a negative pressure will be generated on one side of the liquid inlet layer 11 of the atomizing core 10, which will affect the continued flow of the atomizing medium. In order to compensate for the pressure and ensure the smooth liquid guiding of the atomizing core 10, the atomizing core 10 also has a balance channel 19. The two opposite ends of the balance channel 19 are respectively connected to the liquid inlet hole f and the exhaust hole 112, so as to balance the air pressure of the liquid guiding channel connected to each liquid inlet hole f, so as to ensure the smooth liquid guiding and air guiding.

[0105] Understandably, the balance channel 19 can also be set on the liquid guiding layer 14. The number of balance channels 19 corresponds to the number of liquid inlet holes f, so as to ensure that each liquid inlet hole f has a corresponding balance channel 19 for gas pressure balance.

[0106] Thus, see Figure 1 In one embodiment of this application, an atomizing core 10 is provided, which is arranged in sequence from liquid inlet layer 11, refining layer 12, capturing layer 13, liquid guiding layer 14, atomizing layer 15, and air inlet layer 16. Preferably, when it is necessary to form a mixture of two media, the liquid inlet hole f includes a first liquid inlet hole 111 and a second liquid inlet hole 113, and a kind of atomizing medium flows into each liquid inlet hole f to achieve the mixing of two different atomizing media.

[0107] The multiple layered structures proposed in the atomizing core 10 (including but not limited to the liquid inlet layer 11, the refining layer 12, the capturing layer 13, the liquid guiding layer 14, the atomizing layer 15, and the air inlet layer 16) can be single-layer structures or multi-layer composite structures. They can also be set as opposite sides of a structure to form different structural layers according to their positions. This application does not limit them here.

[0108] Furthermore, the multiple layered structures (including but not limited to the liquid inlet layer 11, the refining layer 12, the capturing layer 13, the liquid guiding layer 14, the atomizing layer 15, and the air inlet layer 16) can be made of laser-transparent, bondable materials that are safe for human use and can operate stably at at least 250 degrees Celsius. Examples include plastics, glass, and semiconductors (e.g., silicon). Glass materials, such as K9 (glass products made from K9 material) and fused silica, are preferred. These materials allow for direct laser-based, highly reliable stacking of multiple transparent and non-transparent layers, simplifying the manufacturing process of the atomizing core 10 and reducing costs.

[0109] The materials described above do not contain small powder particles or metal components to ensure the safety of the atomizer during use. The diameter of a single layer of material is 2-12 inches, preferably 8-12 inches, and the thickness of a single layer is in the range of 30um-3000um, with a preferred thickness in the range of 50-1000um.

[0110] Furthermore, the atomizing core 10 provided in the above embodiments can be achieved using high-temperature diffusion bonding below the glass softening point or laser transmission bonding techniques. Because multi-layer bonding is performed on a large-area wafer, and the finished product is cut into individual atomizing cores 10, the entire manufacturing process utilizes a wafer-level process, achieving very low production costs and high production efficiency in mass production.

[0111] In one specific embodiment, when two atomizing media with different physical properties are mixed, the following example is the mixing of water and oil:

[0112] Based on structure, there are three basic flow patterns: coaxial flow, cross flow, and flow focusing. Under different flow rates and fluid properties, multiple instability patterns can occur, and droplet formation processes can be categorized as extrusion, trickle, and jet. The wettability of the capillary microchannels 1511 determines the multiphase flow generation pattern. From the perspective of the aqueous phase, multiple capillary microchannels 1511 have hydrophilic or hydrophobic coatings. When the contact angle between the water interface and the capillary microchannels 1511 is acute, the wall is called hydrophilic; otherwise, it is hydrophobic. Hydrophilic flow channels can generate oil-in-water droplets, while hydrophobic flow channels can generate water-in-oil droplets. Furthermore, since water has a lower viscosity than oil, leakage is more likely. Hydrophobic coatings also help retain water or water-based liquids and prevent leakage during non-use.

[0113] In this application, it is preferred to select water-in-oil droplets after mixing. Furthermore, to ensure a more uniform droplet diameter distribution, it is preferred to generate a long-range ordered mixed phase of two liquids with different physical properties in a droplet state. Hydrophilic and hydrophobic coatings can be achieved using magnetron sputtering, chemical vapor deposition (CVD), or plasma-assisted CVD processes. For example, using a CVD (chemical vapor deposition) DLC film (diamond-like carbon film), different hydrophilic and hydrophobic properties can be controlled by changing the F (fluorine) content and the content of the weakly polarizing functional group CF2 (difluoride group).

[0114] In one embodiment, see [reference] Figure 6 The atomizing core 10 also includes a first silicone pad 171 and a second silicone pad 172. The second silicone pad 172 is attached to the liquid inlet layer 11, and the first silicone pad 171 is attached to the other side of the second silicone pad 172. Thus, the atomizing core 10 and the mouthpiece 20 are sealed together by the arrangement of the first silicone pad 171 and the second silicone pad 172.

[0115] Furthermore, the atomizing core 10 also includes a support member 18, which is disposed between the first silicone pad 171 and the second silicone pad 172 to improve the structural strength of the atomizing core 10.

[0116] In one embodiment, see [reference] Figure 6 The atomizing core 10 also includes a third silicone pad 173, which is attached to the side of the air intake layer 16 facing away from the atomizing layer 15 to ensure the air intake layer 16 is sealed.

[0117] According to another aspect of this application, an atomizer 100 is provided, see reference. Figures 7 to 9The atomizer 100 includes a mouthpiece 20 and an atomizing core 10 as described in any of the above embodiments. The atomizing core 10 is fitted inside the mouthpiece 20. The mouthpiece 20 has an inhalation port 21 on the side opposite to the atomizing core 10. The inhalation port 21 is connected to the exhaust port 112. The aerosol discharged from the exhaust port 112 enters the user's mouth through the inhalation port 21 along with the user's inhalation action, thereby completing the inhalation process.

[0118] Furthermore, when the inlet port f includes a first inlet port 111 and a second inlet port 113, the nozzle 20 is provided with a first liquid storage chamber 221 and a second liquid storage chamber 222. The first liquid storage chamber 221 is connected to the first inlet port 111, and the second liquid storage chamber 222 is connected to the inlet port 114. This allows different atomizing media to be delivered to different inlet ports f.

[0119] Specifically, see Figure 8 The nozzle 20 also has a central tube 23 inside. When the user performs a suction action, the first liquid storage chamber 221 and the second liquid storage chamber 222 start supplying liquid, so that the two atomizing media are mixed in the atomizing core 10 and atomized to generate an aerosol, which flows through the exhaust port 112 to the central tube 23 and reaches the user's mouth, completing the entire suction process. Optionally, oil can be stored in the first liquid storage chamber 221 and water can be stored in the second liquid storage chamber 222.

[0120] Since the atomizer 100 includes the atomizing core 10 in any of the above embodiments, it has all the features of the atomizing core 10 described above, which will not be repeated here.

[0121] According to another aspect of this application, see Figures 10 to 13 Atomizing device 1000 is provided, including a main body 200 and an atomizer 200 as described in any of the above embodiments. The main body 200 includes a heating component 210. The atomizing core 10 is used to guide the atomizing medium to the atomizing zone 154. The heating component 210 is used to heat the atomizing medium on the atomizing zone 154 to generate an aerosol. The generated aerosol is discharged through the inhalation port 21 of the mouthpiece 20 for the user to inhale.

[0122] In one embodiment, see [reference] Figure 12 The main body 200 also includes a housing 220, one end of the atomizer 200 is connected to the housing 220, and a power supply component (not shown) is provided inside the housing 220 to provide power to the heating component.

[0123] In one embodiment, see [reference] Figure 11The heating assembly 210 has a heating section 211 facing the atomization zone 154. The heating section 211 is a first laser irradiation section, which heats the aerosol generation matrix in the atomization zone 154 by laser irradiation. The laser can be one or more beams. One or more laser beams irradiate the atomization zone 154, and the atomization zone 154 absorbs and stores energy, thereby enabling the atomization of the mixed medium flowing into the atomization zone 154.

[0124] In one embodiment, when the liquid inlet hole f includes multiple inlets, such as the embodiment described above where the liquid inlet hole f includes a first liquid inlet hole 111 and a second liquid inlet hole 113, the heating component 210 may include an adjustment unit (not shown) that adjusts the flow parameters of the atomizing medium flowing out of the first liquid inlet hole 111 and / or the second liquid inlet hole 113 to change the mixing ratio of the atomizing medium after it is mixed with another atomizing medium.

[0125] This allows for the mixing of different atomizing media during the user's inhalation process, as well as the adjustment of their mixing ratios, further enabling personalized customization for different users and enriching the flavor. The flow parameters of the atomizing media can include flow velocity, flow area, or other parameters.

[0126] Specifically, the adjustment unit is a second laser irradiation unit, and the adjustment unit is configured to adjust the flow rate of the atomized medium flowing out of the first liquid inlet 111 and / or the second liquid inlet 113 by changing the power or wavelength of the laser irradiation.

[0127] Specifically, for example, during the flow of the atomized medium introduced through the first liquid inlet 111 from the capillary microchannel 1511, its flow speed will change after being irradiated by the second laser irradiation unit, thereby reducing its proportion in the final mixed medium. In this way, the proportion of different atomized medium components can be controlled by the different irradiation positions of the second laser irradiation unit on the capillary microchannel 1511.

[0128] Specifically, the first laser irradiation unit and the second laser irradiation unit can be semiconductor lasers, fiber lasers or solid-state lasers. Preferably, since semiconductor mechanical chips have the smallest size and the highest photoelectric conversion efficiency, it is recommended to use semiconductor lasers for direct output.

[0129] Preferably, the wavelength range of the laser is 700-1600nm, the laser power emitted by the first laser irradiation unit is 1-10W, and the laser power emitted by the second laser irradiation unit is 0.1-3W.

[0130] Specifically, such as Figure 11 and Figure 13The heating component 210 is attached to the side of the air intake layer 16 facing away from the atomizing layer 15. The heating component and the atomizing core 10 are sealed together by the third silicone pad 173. When the heating component emits a laser, the laser can only pass through the third silicone pad 173 and the air intake layer 16 to irradiate the atomizing layer 15, and will not leak from other positions.

[0131] Furthermore, laser control is used to influence the Reynolds number by adjusting the viscosity coefficient of the mixed medium in the capillary microchannel, thereby enabling real-time online adjustment of various component ratios. Moreover, by utilizing the different gas phase transition temperatures of different liquid media in the mixed medium, secondary atomization through "micro-explosions" during the atomization process can significantly reduce the droplet diameter in the aerosol, resulting in better absorption.

[0132] Meanwhile, because the yarn microchannels are atomized by laser heating, there are no internal electrical connections, and the heating element material has no sintered particulate phase, which further enhances safety. Furthermore, the wafer-level manufacturing process can significantly reduce costs during mass production.

[0133] Especially when using water-in-oil liquid particles, the lower vaporization temperature of water causes the droplets to burst internally first. The resulting micro-explosive droplets continue to atomize at high temperatures, creating a secondary atomization effect with even finer particles, significantly improving the body's absorption efficiency. Furthermore, its compatibility with water-soluble flavorings and other substances allows for greater flexibility in taste adjustments. More importantly, unlike traditional emulsions which cannot be stored for long periods, this design generates emulsions in real-time. The water-in-oil liquid particles not only achieve smaller particles through secondary atomization but also significantly reduce the dehydration and redness of the respiratory mucosa caused by the hygroscopic nature of glycerin. The water-containing aerosol also provides excellent moisturizing and humidifying effects. The water content ranges from 1% to 60% by weight, with 10% to 30% being preferred.

[0134] Furthermore, the total cross-sectional area of ​​the inlet 161 can be smaller than that of the exhaust 112. This allows the gas to undergo a first-time airflow acceleration in the inlet layer 16 due to the reduced inlet area. This, in turn, stimulates a second-time acceleration of the airflow field formed by the micro-explosion effect of the water-in-oil droplets over a larger outlet area. This increases the speed of the aerosol movement, resulting in better satisfaction and reduced power requirements for the laser source.

[0135] The atomizing device 1000 provided in this application has the following advantages:

[0136] 1. In terms of functionality, it achieves the ability to mix the atomizing medium. It can mix the atomizing medium for a long time during use, resulting in a more complex taste of aerosol and a better user experience.

[0137] 2. In terms of controllability, the mixing ratio of different atomizing media can be adjusted, and the online mixing ratio can be adjusted in real time during the user's inhalation process, thereby achieving personalized customization.

[0138] 3. In terms of atomization effect, it can obtain particles with smaller atomization size to improve the absorption efficiency of the human body, thereby reducing the frequency of use.

[0139] 4. In terms of cost control, the existing ceramic atomizing heating element is replaced with a more mass-production process, which greatly reduces the cost of the atomizing core 10 in mass production. Moreover, the materials used in its production are more environmentally friendly, and the generated aerosol mist is safer.

[0140] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0141] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
