Figures 1-3 show an electronic atomization device 100 in some embodiments of the present invention. The electronic atomization device 100 can be used to atomize a liquid substrate to generate an aerosol, which can be smoked or inhaled by the user. In this application, In embodiments, it may be substantially cylindrical. It is understandable that in other embodiments, the electronic atomization device 100 may also be in other shapes such as an elliptical column, a flat column, a square column, or the like. The liquid substrate may include e-liquid or medicinal liquid.

The electronic atomization device 100 may include a housing 10 and a control module 20 contained in the housing 10 , a power supply 30 , an air source 40 , a liquid storage atomization assembly 60 and a bracket assembly 70 . The air source 40 is connected to the liquid storage atomization assembly 60 for providing high-speed air flow, which can usually be an air pump. The control module 20 is electrically connected to the air source 40 for receiving instructions. The instructions can be triggered by the user or automatically triggered after the electronic atomization device 100 meets certain conditions. The control module 20 then controls the operation of the air source 40 according to the instructions. The power supply 30 is electrically connected to the control module 20 and the air source 40 respectively, and is used to provide electric energy to the control module 20 and the air source 40 .

The liquid storage atomization assembly 60 can be supported on the bracket assembly 70. The liquid storage atomization assembly 60 is formed with a liquid storage chamber 610 for storing the liquid substrate, an air flow channel 630 for atomizing the liquid substrate to generate liquid particles, and a communicating storage chamber. The liquid chamber 610 and the liquid supply channel 620 of the air flow channel 630. Further, the air flow channel 630 is connected with the air source 40 , and the liquid substrate entering the air flow channel 630 from the liquid supply channel 620 can be atomized by the high-speed air flow flowing in the air flow channel 630 to form fine liquid particles. An air suction port 14 is provided at one end of the housing 10. The air suction port 14 is connected with the air flow channel 630 and is used to output the atomized liquid particles for the user to suck or inhale.

The housing 10 may also be provided with a vent pipe 80 , the inner wall of the vent pipe 80 defines an output channel 81 , and the output channel 81 connects the air flow channel 630 with the air suction port 14 . Specifically, in this embodiment, the output channel 81 extends longitudinally, the upper end of the output channel 81 is connected to the suction port 14 , and the lower end of the output channel 81 is connected to the upper end of the airflow channel 630 .

Specifically, as shown in FIGS. 3-5 , the liquid storage atomization assembly 60 may include a liquid storage assembly 61 and a nozzle 63 at least partially accommodated in the liquid storage assembly 61 . An airflow channel 630 is formed in the nozzle 63 and can penetrate the nozzle 63 in the longitudinal direction. The air flow channel 630 may include an air supply channel 632 and an atomization channel 631. The atomization channel 631 communicates with the air source 40 through the air supply channel 632, and communicates with the liquid storage chamber 610 through the liquid supply channel 620. An end surface of the atomization channel 631 close to the air supply channel 632 forms an atomization surface 6313, and an atomization port 6310 is also formed on the atomization surface 6313. The high-speed airflow from the air supply channel 632 is sprayed into the atomization channel 631 through the atomization port 6310 and flows at high speed in the atomization channel 631. The high-speed airflow is generated in the atomization channel 631 and the liquid supply channel 620 by Bernoulli's equation. Negative pressure is transmitted to the liquid storage chamber 610 to suck the liquid matrix in the liquid storage chamber 610 to the atomization channel 631, and a liquid film is formed on the atomization surface 6313. As the liquid supply process continues, the liquid film moves to the edge of the hole wall of the atomization port 6310 and meets the high-speed airflow, and is cut and atomized by the high-speed airflow into fine liquid particles. The liquid particles are then taken away from the atomization port 6310 by the airflow. Then it is sprayed out with the airflow to complete the atomization process. The atomization mode of the liquid matrix in the atomization channel 631 is a non-phase change atomization mode. The particle size distribution of the liquid particles formed after atomization in the atomization channel 631 can reach the range of SMD=30 μm. Among them, SMD = total volume of liquid particles/total surface area of liquid particles, which represents the average particle size of liquid particles.

The atomization channel 631 includes an atomization chamber 6311, and the bottom surface of the atomization chamber 6311 forms an atomization surface 6313. The atomization chamber 6311 can be a straight cylindrical channel, the hole wall surface of which is perpendicular to the atomization surface 6313. In this embodiment, the atomization chamber 6311 is a right cylindrical channel, the atomization surface 6313 is in the shape of concentric rings, and the inner wall surface of the atomization surface 6313 defines the atomization port 6310. In other embodiments, the cross-section of the atomization chamber 6311, the atomization surface 6313, or the atomization port 6310 may also be an ellipse, a rectangle, or other non-circular shapes.

Parameters such as the size and shape of the atomization port 6310 and the atomization chamber 6311 can affect the negative pressure in the atomization chamber 6311 and the particle size of the generated liquid particles, and can make the flow rate more stable. In some embodiments, the aperture of the atomization port 6310, the aperture of the atomization chamber 6311, and the length of the atomization chamber 6311 can be set to appropriate sizes as needed.

Specifically, the aperture of the atomization port 6310 is related to the airflow velocity (m/s) coming out of the atomization port 6310, which can affect the particle size of the generated liquid particles. In some embodiments, the aperture range of the atomization port 6310 may be 0.2mm~0.4mm, preferably 0.22mm~0.35mm.

The aperture of the atomization chamber 6311 will affect the airflow velocity in the atomization chamber 6311, thereby affecting the negative pressure in the atomization chamber 6311 and the liquid supply channel 620. This negative pressure can cause the liquid substrate to be sucked from the liquid supply channel 620 to the atomization chamber 6311. In some embodiments, the aperture of the atomization chamber 6311 may range from 0.7 mm to 1.3 mm. The axial length of the atomization chamber 6311 can be 0.8mm~3.0mm. It can be understood that in other embodiments, the atomization port 6310 or the atomization chamber 6311 may also have a non-circular cross-section; when the atomization port 6310 or the atomization chamber 6311 has a non-circular cross-section, the aperture of the atomization port 6310 Or the aperture of the atomization chamber 6311 is its equivalent diameter respectively. The term "equivalent diameter" means that the diameter of a circular hole with the same hydraulic radius is defined as the equivalent diameter of a non-circular hole.

Further, in some embodiments, the aperture range of the atomization port 6310 is 0.22mm~0.35mm, the axial length range of the atomization chamber 6311 is 1.5mm~3.0mm, and the aperture range of the atomization chamber 6311 is 0.7mm~ 1.3mm, this value range can give the liquid storage atomization assembly 60 advantages in the manufacturing process.

One end of the liquid supply channel 620 that communicates with the atomization chamber 6311 has a liquid inlet 6210. The vertical distance between the center of the liquid inlet 6210 and the atomization surface 6313 is the key to ensuring the formation of a liquid film. In some embodiments, the vertical distance between the liquid inlet 6210 and the atomization surface 6313 may range from 0.3mm to 0.8mm, preferably from 0.35mm to 0.6mm.

Further, the atomization channel 631 also includes an expansion channel 6312, which is connected to an end of the atomization chamber 6311 away from the air supply channel 632, and is used to displace the liquid particles generated after atomization in the atomization chamber 6311 in the form of a jet. Diffusion sprays out to increase the spray area of liquid particles. The cross-sectional area of the expansion channel 6312 gradually increases from the end close to the atomization chamber 6311 to the end far away from the atomization chamber 6311. Specifically, in this embodiment, the expansion channel 6312 is a conical channel that extends longitudinally and has a hole diameter that gradually increases from bottom to top. The atomization angle of the expansion channel 6312 (that is, the expansion angle of the expansion channel 6312) must have a suitable range to ensure that the ejected liquid particles have a suitable spray range. Furthermore, a streamlined smooth connection can also be used between the expansion channel 6312 and the atomization chamber 6311, for example, by rounding the corners. In other embodiments, the expansion channel 6312 may also be in an elliptical cone shape, a pyramid shape, or other shapes.

In some embodiments, the air supply channel 632 may include a constriction channel 6321. The constriction channel 6321 has a constriction shape, and its cross-sectional area gradually decreases from an end far away from the atomization chamber 6311 to an end close to the atomization chamber 6311, thereby enabling the air supply channel 632 to be compressed. The air flow from the air source 40 is accelerated and then sprayed to the atomization chamber 6311. In this embodiment, the contraction channel 6321 is a conical channel extending longitudinally and with aperture gradually decreasing from bottom to top. The upper end aperture of the contraction channel 6321 is smaller than the aperture of the atomization chamber 6311, so that the contraction channel 6321 and the atomization chamber 6311 The junction forms a circular atomization surface 6313. It can be understood that in other embodiments, the contraction channel 6321 can also be an elliptical cone shape or a pyramid shape or other contraction shapes.

The liquid supply channel 620 can be used to control the flow rate of liquid supplied from the liquid storage chamber 610 to the atomization chamber 6311, to realize quantitative liquid supply to the atomization cavity 6311, and to ensure that the flow rate of liquid supply to the atomization cavity 6311 reaches the design value. Generally, the size of the liquid supply channel 620 can be designed according to the flow demand, that is, the liquid supply channel 620 can generate resistance that matches the liquid supply power under the designed flow rate. Specifically, the negative pressure generated in the atomization chamber 6311 is the liquid supply power, and the liquid supply resistance includes the resistance along the liquid supply channel 620 and the negative pressure in the liquid storage chamber 610 . By calculating the resistance required along the liquid supply channel 620 under the design flow rate, the specific diameter and length of the liquid supply channel 620 are designed.

Generally speaking, the greater the viscosity of the liquid matrix, the greater the resistance when the liquid matrix circulates in the liquid supply channel 620; the longer the extension path of the liquid supply channel 620, the greater the resistance in the liquid supply channel 620; The larger the cross-sectional area of the channel 620 is, the smaller the resistance in the liquid supply channel 620 is; the more tortuous the liquid supply channel 620 is, the greater the resistance in the liquid supply channel 620 is.

Further, the liquid supply channel 620 may include a main channel 622 and a liquid inlet channel 621. The main channel 622 is connected to the liquid storage chamber 610, and the liquid inlet channel 621 connects the main channel 622 to the atomization chamber 6311. The liquid inlet channel 621 may be a linear channel that can extend laterally, and its extension direction is perpendicular to the extension direction of the air flow channel 630 . Further, the liquid inlet channel 621 may be a capillary channel. By designing the liquid inlet channel 621 as a capillary channel, when the air source 40 stops working and the negative pressure generated by the high-speed air flow in the liquid supply channel 620 disappears, the capillary force in the liquid inlet channel 621 can be used to reduce or avoid the inlet. The backflow of the liquid matrix in the liquid channel 621 to the liquid storage chamber 610 prevents the liquid supply delay in the next suction caused by the backflow of the liquid matrix in the liquid inlet channel 621.

In this embodiment, the main channel 622 and the liquid inlet channel 621 are formed in the liquid storage component 61 and the nozzle 63 respectively. It can be understood that in other embodiments, the main channel 622 can also be partially formed in the liquid storage assembly 61 and partially formed in the nozzle 63; or, the liquid inlet channel 621 can also be partially formed in the liquid storage assembly 61 and partially formed in the nozzle 63. formed in the nozzle 63.

The liquid storage chamber 610 is formed in the liquid storage assembly 61 , and the nozzle 63 is longitudinally disposed in the liquid storage assembly 61 . Both the liquid storage assembly 61 and the nozzle 63 may have a generally cylindrical shape. Furthermore, the liquid storage component 61 may also be formed with a liquid injection channel 614, so that after the liquid matrix in the liquid storage cavity 610 is used up, liquid can be injected into the liquid storage cavity 610 again through the liquid injection channel 614. In this embodiment, the liquid injection channel 614 may extend longitudinally upward from the upper end of the liquid storage chamber 610 . The liquid storage atomization assembly 60 may also include a sealing plug 64 that can be detachably blocked in the liquid injection channel 614 . When liquid injection is not required, the liquid injection channel 614 can be sealed and blocked by the sealing plug 64 to prevent the liquid matrix in the liquid storage chamber 610 from leaking.

Specifically, in this embodiment, the liquid storage assembly 61 may include a liquid storage body 611, a liquid storage seat 612 embedded at the bottom of the liquid storage body 611, and a liquid storage seat 612 sealingly provided between the liquid storage body 611 and the liquid storage seat 612. Sealing sleeve 613. The liquid storage chamber 610 is formed in the liquid storage body 611 , and the liquid storage seat 612 is fitted at the lower end opening of the liquid storage chamber 610 to cover the liquid storage chamber 610 . In some embodiments, the liquid storage body 611 and the liquid storage seat 612 can be made of hard materials such as plastic. The sealing sleeve 613 can be made of elastic materials such as silicone to improve its sealing performance.

Furthermore, a receiving cavity 619 for receiving the breather tube 80 may also be formed in the liquid storage body 611 . In this embodiment, the central axes of the liquid storage cavity 610 and the receiving cavity 619 are parallel to the central axis of the liquid storage assembly 61 respectively. The inner wall surface of the liquid storage body 611 only partially defines the liquid storage cavity 610, so that the liquid storage cavity The cross section of 610 has a roughly C-shaped structure, and the receiving cavity 619 is provided on the side of the liquid storage body 611 that does not define the liquid storage cavity 610. This structural design can save the space of the liquid storage body 611 in the lateral direction, so that it takes up space. less. The nozzle 63 is located directly below the receiving cavity 619 and is coaxially arranged with the receiving cavity 619 , that is, the central axis of the nozzle 63 is parallel to the central axis of the liquid storage assembly 61 .

The main channel 622 may be formed between the liquid storage body 611 and the liquid storage seat 612 . Specifically, in this embodiment, the lower end surface of the liquid storage body 611 is concavely formed with a liquid guide groove 6111. The liquid guide groove 6111 can be formed from a side wall of the liquid storage chamber 610 close to the nozzle 63 in a transverse direction toward the nozzle 63. extension, which in this embodiment is a linear channel extending laterally. The upper end surface of the liquid storage seat 612 is a flat surface. After the liquid storage main body 611 and the liquid storage seat 612 are assembled together, the lower end surface of the liquid storage main body 611 fits the upper end surface of the liquid storage seat 612. The upper end surface of the liquid storage seat 612 A main channel 622 is defined between the liquid guide groove 6111 and the liquid guide groove 6111 . The main channel 622 in this embodiment is formed by fitting the lower end surface of the liquid storage body 611 and the upper end surface of the liquid storage seat 612, so that the main channel 622 can be designed into different shapes and sizes according to different resistance requirements, for example , various non-linear shapes such as S-shape, square wave shape or polygonal shape, the surface shape is easy to process and manufacture, and the dimensional accuracy is easy to control. In other embodiments, the lower end surface of the liquid storage body 611 can also be a flat surface, and the liquid guide groove 6111 is formed on the upper end surface of the liquid storage seat 612 . In other embodiments, the main channel 622 may also be formed between two other mating components, such as between the liquid storage body 611 and the sealing sleeve 613 , or between the liquid storage seat 612 and the sealing sleeve 613 .

Further, the liquid storage atomization assembly 60 may also include an air supply sleeve 68 that is sleeved on the lower part of the liquid storage assembly 61 . The air supply sleeve 68 is annular, and is sealably disposed between the outer wall surface of the liquid storage body 611 and the inner wall surface of the housing 10 . In some embodiments, the air supply sleeve 68 can be made of elastic materials such as silicone.

As shown in Figures 2-4 and 6, an air supply channel 12 can also be formed in the housing 10, and an air supply port 11 is also provided on the side wall of the housing 10. The air supply port 11, the air supply channel 12, the output channel 81, the suction channel 81, The air ports 14 are connected in sequence. When the user inhales at the air suction port 14 , external air can enter the air supply channel 12 from the air supply port 11 and then be output to the air suction port 14 . The air supply channel 12 can be used for the air supply function of the electronic atomization device 100, so that the electronic atomization device 100 can realize a composite air supply mode in which part of the air source 40 actively supplies air and part of the user inhales. The air supply provided by the air source 40 The sum of the high-speed air flow and the air supplied through the air supply port 11 is the total air volume required by the user. In addition, the air supply channel 12 can also be used to cooperate with the user's habitual suction action to improve the user experience, and can also help the atomized aerosol to flow out smoothly. Furthermore, in this embodiment, the air supply channel 12 and the air flow channel 630 are isolated from each other to avoid their mutual influence.

Furthermore, a ventilation channel 616 may also be formed in the housing 10 . The ventilation channel 616 connects the liquid storage chamber 610 to the outside world and is used to restore the pressure in the liquid storage chamber 610 and solve the problem caused by the negative pressure in the liquid storage chamber 610 . Too large to provide stable fluid supply. During the suction process, the reduction of the liquid matrix in the liquid storage chamber 610 will cause the air pressure to decrease. When the negative ventilation pressure reaches the limit, air bubbles will enter the liquid storage chamber 610 through the ventilation channel 616 and the negative pressure of the liquid storage chamber 610 will be restored. The ventilation channel 616 cooperates with the negative pressure area of the atomization channel 631 to realize automatic and stable liquid supply to the atomization channel 631. Generally, the controllable negative pressure range of the liquid storage chamber 610 is -200Pa ~ -700Pa.

The extension length of the air return groove 683 is smaller than the axial length of the air supply sleeve 68 , preventing the air return groove 683 from penetrating the lower end inner wall of the air supply sleeve 68 longitudinally, and ensuring that the air return groove 683 is isolated from the gap cavity 671 . In addition, the air supply grooves 682 and the air return grooves 683 are staggered in the circumferential direction of the air supply sleeve 68 and are not connected with each other. It is understood that in other embodiments, the air return groove 683 may also be formed on the outer surface of the liquid storage body 611 , or may be formed on both the outer surface of the liquid storage body 611 and the inner surface of the air supply sleeve 68 .

The ventilation main channel 6120 may also include an air flow groove 6124 that communicates the plurality of rotation grooves 6121 and the plurality of communication grooves 6122 with the air return port 6112.

The inner wall surface of the air supply sleeve 68 can also be provided with a wire groove 684 for the electrode leads of the heating element 83 to pass through. The positive and negative poles of the heating element 83 are electrically connected to the power supply 30 through two electrode leads respectively. The structure and heating form of the heating element 83 are not limited. For example, it can be a heating net, a heating sheet, a heating wire or a heating film. The heating form can be resistance conduction heating, infrared radiation heating, electromagnetic induction heating or composite heating. Heated form. In this embodiment, the heating element 83 is located above the nozzle 63, and the liquid particles sprayed from the nozzle 63 are sprayed upward into the output channel 81.

This embodiment uses the nozzle 63 to atomize the continuously flowing liquid matrix into liquid particles and then evaporates the heating element 83. Since the surface area of the fine liquid particles formed after atomization by the nozzle 63 is greatly expanded, it is easier to Heating and evaporation can, on the one hand, improve the conversion efficiency of heat and aerosol, and on the other hand, reduce the temperature of the evaporation process of the heating element 83 to achieve low-temperature atomization. At a lower heating atomization temperature, the liquid matrix mainly completes the physical change process, thus overcoming the problem of thermal cracking and deterioration of the liquid matrix caused by the necessity of high-temperature atomization under traditional porous ceramics or porous cotton conditions, not to mention the Burning, carbon deposition, heavy metal volatilization and other phenomena will occur, so that the unique ingredients and flavor and fragrance systems of different liquid bases can be maintained, and ultimately the inhaler can feel the unique taste corresponding to the original liquid base. In addition, the heating element 83 is not in contact with the liquid storage chamber 610, and the heating element 83 does not need to be immersed in the liquid matrix for a long time, which reduces the contamination of the liquid matrix by the heating element 83, thereby reducing impurity gases in the aerosol generated after atomization.

It can be understood that in other embodiments, the liquid particles ejected from the nozzle 63 can also hit the heating element 83 downward, that is, the heating element 83 can also be disposed below the nozzle 63; or, the liquid ejected from the nozzle 63 can The particles may also impact the heating element 83 laterally, that is, the heating element 83 and the nozzle 63 are at or approximately at the same level.

Figures 7-12 illustrate ventilation passages 616 in some alternatives of the present invention, as an alternative to the direct liquid ventilation passages 616 in the above embodiments. In the alternative shown in FIGS. 7-12 , the forward flow and reverse flow of fluid in the ventilation channel 616 have different flow resistances, where the forward flow direction refers to the fluid flowing from the liquid storage chamber 610 to the ventilation channel 616 . The direction in which the channel 616 flows out. The reverse flow direction refers to the direction in which fluid flows from the ventilation channel 616 into the liquid storage chamber 610 . The flow resistance when the fluid flows forward in the ventilation channel 616 is greater than the flow resistance when the fluid flows in the reverse direction, thereby making ventilation smooth and reducing the risk of liquid leakage.

In the first alternative shown in FIGS. 7-9 , the ventilation channel 616 includes a main channel 6161 and several branch channels 6162 provided on at least one side of the main channel 6161 . The main channel 6161 is a linear channel, which has a first end 6163 connected with the liquid storage chamber 610 and a second end 6164 opposite to the first end 6163. The branch channel 6162 is also a linear channel, with one end connected to the main channel 6161 and the other end extending away from the main channel 6161 . Preferably, there are multiple branch channels 6162, and the multiple branch channels 6162 can be symmetrically arranged on two opposite sides of the main channel 6161, so that the ventilation channel 616 has a herringbone shape as a whole. The hydraulic diameter of the main channel 6161 and the branch channel 6162 can be between 0.1mm and 1mm. The angle θ between the two branch channels 6162 on both sides of the symmetry can be between 30° and 150°.

As shown in Figure 8, when the liquid matrix flows forward from the liquid storage chamber 610 to the second end 6164 of the main channel 6161, due to the contact angle between the liquid and the solid wall of the channel, under the wetting action of the solid wall , the liquid matrix first fills the branch channels 6162 on the left and right sides, and then continues to flow in the direction of the second end 6164 of the main channel 6161, causing the flow resistance of the liquid matrix in the ventilation channel 616 to increase. As shown in Figure 9, when the liquid matrix flows in the opposite direction from the second end 6164 to the first end 6163 of the main channel 6161, since the wetting direction of the solid wall surface is consistent with the initial flow direction of the liquid matrix, the liquid matrix is changing. Flow resistance in air passage 616 is reduced. By adopting this fishbone-shaped ventilation structure, when the liquid storage chamber 610 is ventilated, the bubbles push the liquid matrix to flow in the reverse direction in the ventilation channel 616. The wetting direction of the solid wall is consistent with the initial flow direction of the liquid matrix, and the liquid matrix is Smoothly push back the liquid storage chamber 610; after the ventilation is completed, the liquid matrix flows forward in the ventilation channel 616. The liquid matrix first fills the branch channels 6162 on the left and right sides, and then continues to the second end 6164 of the main channel 6161. Flow makes the flow of liquid matrix sluggish, thereby reducing the risk of leakage.

It can be understood that in other embodiments, the plurality of branch channels 6162 can also be disposed on two opposite sides of the main channel 6161 in a staggered manner, or the plurality of branch channels 6162 can also be disposed on the main channel 6161 of the same side.

In the second alternative shown in FIGS. 10-12 , the ventilation channel 616 also includes a main channel 6161 and several branch channels 6162 provided on at least one side of the main channel 6161 . The main channel 6161 is a linear channel, which has a first end 6163 connected with the liquid storage chamber 610 and a second end 6164 opposite to the first end 6163. Each branch channel 6162 is a continuous curved channel, and both ends thereof are connected with the main channel 6161, so that the ventilation channel 616 as a whole has a Tesla valve ventilation structure. Preferably, there are multiple branch channels 6162, and the multiple branch channels 6162 can be respectively disposed on two opposite sides of the main channel 6161. The hydraulic diameter of the main channel 6161 and the branch channel 6162 can be between 0.1mm and 1mm.

As shown in Figure 11, when the fluid flows forward from the liquid storage chamber 610 to the second end 6164 of the main channel 6161, due to the diverting effect of the branch channel 6162, the direction of the fluid located in the branch channel 6162 is in line with the direction of the main channel. The directions of the fluids in the channels 6161 conflict, which causes the flow resistance of the fluid in the ventilation channel 616 to increase, thereby reducing the risk of liquid leakage. As shown in Figure 12, when the fluid flows backward from the second end 6164 of the main channel 6161 to the liquid storage chamber 610, the fluid in the branch channel 6162 is in the same direction as the fluid in the main channel 6161, causing the fluid to flow in the ventilation channel. The flow resistance in 616 is greatly reduced, which is conducive to the flow of bubbles into the liquid storage chamber 610.

It can be understood that the above technical features can be used in any combination without limitation.
