Electronic atomization device and atomizer thereof

Abstract

The utility model relates to an electronic atomization device and atomizer thereof, and the atomizer comprises: an atomization core having an atomization face; and an airflow channel comprising a gas inlet channel, an atomization cavity and a gas outlet channel connected in sequence, the gas outlet channel extending along a direction parallel to the atomization face, and the atomization face defining part of a cavity wall surface of the atomization cavity. The gas inlet channel comprises a gas outlet, the gas outlet being arranged on a side of the atomization cavity opposite the atomization face, and the side of the gas outlet close to a downstream end of the atomization face being located between an upstream end and a downstream end of the atomization face in projection. In this way, air entering the atomization cavity through the gas outlet blows against the atomization face, and the air entering the atomization cavity through the gas outlet collides with large droplets generated by the atomization core from the liquid, thereby being able to offset or reduce the initial kinetic energy of the large droplets of the liquid in the direction towards the side opposite the atomization face, so that the large droplets are no longer sprayed to the wall surface of the atomization cavity, but are carried upwards by the air to the gas outlet channel.

Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an electronic atomization device and its atomizer. Background Technology

[0002] In electronic atomizing devices that employ lateral atomization, the air outlet extends parallel to the atomizing surface of the atomizing core. The air inlet of the atomizing chamber (i.e., the air outlet of the air inlet channel) is generally located below the atomizing core. Airflow enters the atomizing chamber through the air inlet, sweeps across the atomizing surface of the atomizing core, carries the vapor upwards, and finally enters the oral cavity through the air outlet channel.

[0003] When an atomizer coil is in operation, it may experience liquid spillage. The spilled liquid is sprayed directly onto the inner wall of the atomization chamber, condenses, and then flows into the storage space due to gravity. For some high-performance atomizer coils, the amount of spilled liquid is usually large. After multiple pumps, the amount of spilled liquid may even exceed the total amount of liquid that the storage space can hold. In this case, the liquid will directly overflow the air inlet of the atomization chamber, causing airflow blockage and corrosion of the circuitry below. On the other hand, the large droplets produced by the spilled liquid are often more flavorful and have a positive effect on the taste of electronic atomizers. However, because the air is blown out of the vapor in lateral atomization, this blowing method cannot counteract the lateral inertial potential energy of the spilled liquid, causing a large amount of spilled liquid to be sprayed directly onto the inner wall of the atomization chamber and unable to be carried out.

[0007] The atomizing surface defines a portion of the cavity wall surface of the atomizing chamber.

[0008] The air inlet channel includes an air outlet, which is located on the side of the atomizing chamber opposite to the atomizing surface.

[0009] The atomizing surface has an upstream end and a downstream end, and the projection of the side of the air outlet near the downstream end onto the atomizing surface is located between the upstream end and the downstream end.

[0010] In some embodiments, the atomizing surface has an intermediate position between the upstream end and the downstream end, and the projection of the air outlet on the atomizing surface is located at the intermediate position, or between the intermediate position and the downstream end.

[0011] In some embodiments, the air intake channel includes an air intake port and a communicating air passage connecting the air intake port and the air outlet.

[0012] The air inlet is parallel to the air outlet.

[0013] In some embodiments, the atomizing surface has an intermediate position between the upstream end and the downstream end, and the projection of the air outlet of the air inlet onto the atomizing surface is located at the intermediate position, or between the intermediate position and the downstream end.

The air entering the atomizing chamber through the air outlet collides with the large droplets generated by the atomizing core liquid, thereby offsetting or reducing the initial kinetic energy of the large liquid droplets in the direction toward the atomizing surface, so that they no longer spray onto the wall of the atomizing chamber, but are carried upward by the air to the air outlet channel.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, four, etc., unless otherwise explicitly specified.

[0035] Figures 1 to 3 An electronic atomizing device 1 according to some embodiments of the present invention is shown. The electronic atomizing device 1 includes an atomizer 100 and a power supply 200 connected in conjunction with the atomizer 100. The power supply 200 typically includes a battery 290 for supplying power to the atomizer 100 and a control circuit for controlling the heating of the atomizer 100. The atomizer 100 is used to contain an aerosol generating matrix and, upon being powered on, heats and atomizes the aerosol generating matrix to generate an aerosol.

[0036] In some embodiments, the atomizer 100 and the power supply 200 may have a cylindrical shape, and the two may be mechanically and electrically connected together along the axial direction. Further, the atomizer 100 and the power supply 200 may be detachably connected by means of magnetic connection, threaded connection, snap-fit ​​connection, etc. It is understood that in other embodiments, the atomizer 100 and the power supply 200 may also be non-detachably connected together. Furthermore, the cross-sectional shape of the atomizer 100 and / or the power supply 200 is not limited to a circle; it may also be other shapes such as elliptical, racetrack-shaped, or rectangular.

[0037] like Figures 3 to 5 As shown, the atomizer 100 includes a liquid storage chamber 120, an airflow channel 101, and an atomizing core 30. The liquid storage chamber 120 stores the aerosol generation matrix. The atomizing core 30 is in fluid communication with the liquid storage chamber 120 and is used to atomize the aerosol generation matrix after being powered on. The airflow channel 101 includes an inlet channel 210, an atomizing chamber 310, and an outlet channel 110 connected in sequence. The atomizing core 30 defines at least a portion of the cavity wall of the atomizing chamber 310. When the user inhales, outside air enters the atomizing chamber 310 through the inlet channel 210, carrying the aerosol generated by the atomization of the atomizing core 30 out and outputting it through the outlet channel 110.

[0038] The atomizing core 30 has an atomizing surface 311 exposed in the atomizing chamber 310, defining at least a portion of the chamber wall surface. In some embodiments, the air outlet channel 110 extends in a direction parallel to the atomizing surface 311, or the atomizing surface 311 may be parallel to the axis of the atomizer 100. Of course, in other embodiments, the atomizing surface 311 may also be arranged at an acute angle to the axis of the atomizer 100.

[0039] In some embodiments, the atomizing core 30 may include a liquid-absorbing element 31 and a heating element 32. The liquid-absorbing element 31 has a liquid-absorbing surface 312 and an atomizing surface 311. The liquid-absorbing surface 312 is in fluid communication with the liquid storage chamber 120, and the heating element 32 is disposed on the atomizing surface 311. The liquid-absorbing element 31 may be made of a porous material, such as porous ceramic material, cotton, or fiber material. The liquid-absorbing element 31 draws aerosol generating matrix from the liquid storage chamber 120 through the liquid-absorbing surface 312 and conducts the aerosol generating matrix to the atomizing surface 311. When energized, the heating element 32 heats and atomizes the aerosol generating matrix adsorbed by the liquid-absorbing element 31.

[0040] In some embodiments, the liquid-absorbing element 31 can be flat, such as a cuboid plate. The liquid-absorbing surface 312 and the atomizing surface 311 can be two opposing surfaces on the liquid-absorbing element 31. The atomizing surface 311 is planar, which facilitates the placement of the heating element 32. Of course, in other embodiments, the liquid-absorbing element 31 is not limited to being flat. The placement of the liquid-absorbing surface 312 and the atomizing surface 311 is also not limited. For example, the liquid-absorbing surface 312 and the atomizing surface 311 can also be two adjacent surfaces of the liquid-absorbing element 31. As another example, the liquid-absorbing surface 312 or the atomizing surface 311 can include one surface of the liquid-absorbing element 31 in the thickness direction and one or more side surfaces adjacent to that surface.

[0041] All or at least a portion of the air outlet channel 110 extends in a direction parallel to the axis of the atomizer 100. In some embodiments, the central axis of the air outlet channel 110 may coincide with the central axis of the atomizer 100; however, in other embodiments, the central axis of the air outlet channel 110 may be parallel to but not coincide with the central axis of the atomizer 100. In other embodiments, all or at least a portion of the air outlet channel 110 may be set at an acute angle to the axis of the atomizer 100, or in other words, all or at least a portion of the air outlet channel 110 may be set at an acute angle to the atomizing surface 311. This ensures that the deflection angle of the airflow during its flow from the atomizing chamber 310 into the air outlet channel 110 is less than 90°, resulting in smoother airflow and less smoke loss.

[0042] The air intake channel 210 includes an air outlet 213, through which airflow enters the atomizing chamber 310. The air outlet 213 can be located on the side of the atomizing chamber 310 opposite to the atomizing surface 311. The projection of the side of the air outlet 213 near the downstream end 311b of the atomizing surface 311 onto the atomizing surface 311 is located between the downstream end 311b and the upstream end 311a of the atomizing surface 311.

[0043] In this invention, the terms "upstream end" and "downstream end" describe the relative positions of components or parts of components in the electronic atomizing device 1 based on the direction of airflow during inhalation. The end through which the airflow first flows is called the upstream end, or the air inlet end; the end through which the airflow flows last is called the downstream end, or the air outlet end.

[0044] The atomizer 100 is configured to have X, Y and Z directions that are perpendicular to each other. The X direction is the axial direction of the atomizer 100. The air outlet 213 and the atomizing surface 311 are arranged opposite each other in the Y direction. The downstream end 311b and the upstream end 311a of the atomizing surface 311 are arranged opposite each other in the X direction.

[0045] like Figure 5 The airflow trajectory indicated by the dashed arrow and the smoke (large droplet) flow trajectory indicated by the solid arrow are as follows: the air entering the atomization chamber 310 through the air outlet 213 blows against the atomization surface 311. The air entering the atomization chamber 310 through the air outlet 213 collides with the large droplets generated by the liquid blasting of the atomizing core 30, thereby canceling or reducing the initial kinetic energy of the large liquid droplets in the Y direction. This prevents them from being sprayed onto the wall of the atomization chamber 310, but instead carries them upward to the air outlet channel 110, thereby reducing leakage and improving the taste of the electronic atomization device.

[0046] Furthermore, the projection of the side of the air outlet 213 near the downstream end 311b of the atomizing surface 311 onto the atomizing surface 311 can be located or approximately at the midpoint between the downstream end 311b and the upstream end 311a of the atomizing surface 311, or between the midpoint between the downstream end 311b and the upstream end 311a of the atomizing surface 311 and the downstream end 311b of the atomizing surface 311. The midpoint is located in the X direction, between the downstream end 311b and the upstream end 311a, at an equidistant distance from both ends. This allows the air entering through the air outlet 213 to carry the aerosol generated after atomization by the atomizing core 30 to the air outlet channel 110 as much as possible, and also effectively carries large droplets of the explosive liquid to the air outlet channel 110.

[0047] Furthermore, the atomizer 100 also includes a liquid storage space 220, which is located below the atomizing core 30. By storing condensate, leakage liquid, and other liquids in the liquid storage space 220, the risk of liquid leakage to the outside of the atomizer 100 can be reduced.

[0048] The air intake channel 210 includes an air intake port 211, through which the air intake channel 210 communicates with the outside atmosphere. The lower end of the air intake port 211 can be located at the bottom of the atomizer 100. The air intake port 211 can extend in a direction parallel to the axis of the atomizer 100, that is, the extension direction of the air intake port 211 is parallel to the atomizing surface 311 and parallel to the extension direction of the air outlet channel 110. Of course, in other embodiments, the extension direction of the air intake port 211 can also be set at an acute angle to the axis of the atomizer 100.

[0049] The number of air inlets 211 is unlimited, and there can be one or more. The upper end face of the air inlet 211 (i.e., the air outlet end face) protrudes from the bottom wall of the liquid storage space 220, which can reduce the leakage of liquid stored in the liquid storage space 220 through the air inlet 211.

[0050] In some embodiments, the projection of the air outlet end of the air inlet 211 onto the atomizing surface 311 can be located or approximately located at the midpoint between the downstream end 311b and the upstream end 311a of the atomizing surface 311, or located between the midpoint between the downstream end 311b and the upstream end 311a of the atomizing surface 311 and the downstream end 311b of the atomizing surface 311. This allows for the formation of a large-capacity liquid storage space 220, effectively preventing liquid leakage from the liquid storage space 220 to the outside through the air inlet 211. Furthermore, this structure also allows a large portion of the atomizing chamber 310 to form part of the liquid storage space 220. This increases the size of the liquid storage space 220 and allows the liquid in the liquid storage space 220 to be reabsorbed and atomized by the atomizing core 30, thereby improving the utilization rate of the aerosol generation matrix.

[0051] In some embodiments, the air inlet 211 can be disposed on the side of the liquid storage space 220 opposite to the atomizing surface 311, and a portion of the wall of the air inlet 211 can be integrally combined with a portion of the wall of the liquid storage space 220, which is beneficial to further increase the capacity of the liquid storage space 220.

[0052] For example Figures 4 to 6 As shown, the atomizer 100 may include a housing 10, a base 20, an atomizing seat 50, and a separator 40. A liquid storage chamber 120 and an air outlet channel 110 are formed within the housing 10. The base 20 is fitted to the end of the housing 10 away from the air outlet channel 110 (i.e., the lower end), and the atomizing seat 50 is fitted to the end of the base 20 facing the liquid storage chamber 120. The atomizing core 30 is housed between the base 20 and the atomizing seat 50. A liquid outlet channel 510 is formed on the atomizing seat 50, providing fluid communication between the atomizing core 30 and the liquid storage chamber 120.

[0053] In some embodiments, the atomizer 100 may further include a liquid guide 60, which is in contact with and fluidly communicates with the atomizing core 30. The liquid reservoir 120 is fluidly communicated with the liquid guide 60, and further fluidly communicates with the atomizing core 30 through the liquid guide 60. The liquid guide 60 can rapidly and uniformly conduct the aerosol generating matrix from the liquid reservoir 120 to the liquid absorption surface 312 of the atomizing core 30. The liquid guide 60 can be made of a porous material with a high liquid conduction rate, such as cotton or fibers; alternatively, other materials such as porous ceramics can also be used.

[0054] In some embodiments, the base 20 may include a base 21 and an insert 22 extending upward from the base 21. The base 21 is disposed on the outer side of the housing 10, and the upper end surface of the base 21 may abut against the lower end surface of the housing 10. The insert 22 is disposed in the housing 10 and may be fastened to the housing 10 by a snap-fit ​​structure. Of course, in other embodiments, the insert 22 and the housing 10 may also be fixed together by other means such as riveting or interference fit.

[0055] The embedding part 22 is cylindrical, and its inner wall defines at least a portion of the liquid storage space 220. The atomizing seat 50 fits onto the upper end of the base 20 and seals the upper opening of the liquid storage space 220.

[0056] In some embodiments, the base 20 may be made of a plastic material, which can provide a certain structural strength. Of course, in other embodiments, the base 20 may also be made of other materials such as silicone.

[0057] The atomizer base 50 can be made of elastic materials such as silicone, which has good sealing properties. In addition, the atomizer core 30 can be embedded in the atomizer base 50, and the silicone material can protect the atomizer core 30 from being squeezed and broken during installation.

[0058] An air intake passage 210 can be formed on the base 20 and the partition 40. Specifically, an air intake hole 211 of the air intake passage 210 can be formed on the base 20, and an air outlet 213 can be formed on the partition 40.

[0059] In some embodiments, the base 20 includes an air inlet pipe 23 extending upward from the upper end face of the base 21, and the inner wall surface of the air inlet pipe 23 defines at least a portion of the air inlet hole 211. Specifically, the air inlet hole 211 can extend from the upper end face of the air inlet pipe 23 to the bottom surface of the base 20, thereby communicating with the outside.

[0060] In this embodiment, there are two air inlet pipes 23, located on opposite sides of the air outlet 213 in the Z direction. Each air inlet pipe 23 can be integrally connected to the inner wall of the embedded part 22 opposite to the atomizing surface 311, which helps to increase the liquid storage space 220. Of course, in other embodiments, there may be only one air inlet pipe 23, or there may be more than two. The air inlet pipe 23 may also not be integrally connected to the embedded part 22, but may be spaced apart from the embedded part 22.

[0061] The separator 40 is fixed between the base 20 and the atomizing seat 50, and may include a separator wall 41 and a baffle wall 42. The baffle wall 42 is arranged laterally, and the separator wall 41 is arranged longitudinally. The separator wall 41 may be formed by extending downward from one of the lateral sides of the baffle wall 42. The baffle wall 42 abuts against the lower side of the atomizing seat 50, and the lower end face of the baffle wall 42 abuts against the upper side of the base 20, thereby fixing the separator 40 between the base 20 and the atomizing seat 50.

[0062] The partition wall 41 and the atomizing surface 311 of the atomizing core 30 are spaced apart in the Y direction, forming an atomizing cavity 310 between the partition wall 41 and the atomizing surface 311. An air outlet 213 is formed on the partition wall 41, and it can be formed by a concave shape on the lower end face of the partition wall 41. Of course, in other embodiments, the air outlet 213 can also be spaced apart from the lower end face of the partition wall 41.

[0063] The lower end face of the baffle 42 is spaced apart from the upper end face of the air inlet pipe 23, and the space between the lower end face of the baffle 42 and the upper end face of the air inlet pipe 23 forms a connecting air passage 212. The air inlet 211, the connecting air passage 212, and the air outlet 213 are connected in sequence to form an air intake channel 210.

[0064] A liquid storage tank 410 communicating with the liquid storage space 220 can also be formed on the partition wall 41. The liquid storage tank 410 can be formed by a recess in the side of the partition wall 41 facing the atomizing surface 311. The liquid storage tank 410 is a capillary tank, which can store a certain amount of liquid through capillary force.

[0065] The liquid storage tank 410 is connected to the air outlet 213. Specifically, the liquid storage tank 410 can be connected to the upper side of the air outlet 213. The upper end face of the air inlet 211 is higher than the upper side of the air outlet 213 (that is, the highest point of the air outlet 213). In this way, even if a large amount of liquid is stored in the liquid storage space 220 and reaches the upper side of the air outlet 213, the liquid can be stored in the liquid storage tank 410 by capillary force, so as not to leak from the air inlet 211.

[0066] The separator 40 can be made of an elastic material such as silicone to achieve a seal between the base 20 and the atomizing seat 50. Of course, in other embodiments, the separator 40 can also be made of other materials such as plastic.

[0067] In some embodiments, the atomizer 100 may further include two electrode assemblies 80, which are electrically connected to the two poles of the heating element 32 of the atomizing core 30, thereby electrically connecting the heating element 32 to the power supply device 200.

[0068] The electrode assembly 80 can be disposed on the base 20. In some embodiments, the electrode assembly 80 may include an electrode post that extends longitudinally through the base 20. The upper end of the electrode post protrudes outside the base 20. When the atomizing seat 50, in which the atomizing core 30 is embedded, is installed on the base 20, the upper end of the electrode post can press against the heating element 32 of the atomizing core 30, thereby making contact and conducting between the electrode post and the heating element 32. Of course, in other embodiments, the electrode assembly 80 may also include other electrode connectors such as electrode connecting pieces or electrode leads.

[0069] In some embodiments, the atomizer 100 may further include an air exchange tube 70, the inner wall of which defines an air exchange hole that connects the liquid storage chamber 120 to the outside atmosphere.

[0070] The upper end of the air exchange tube 70 can be embedded in the atomizing base 50, and the upper end of the air exchange tube 70 is connected to the liquid storage chamber 120. The air exchange tube 70 can be made of metal materials such as stainless steel, or other materials such as plastic or silicone. Of course, in other embodiments, the air exchange tube 70 can also be integrally formed with the atomizing base 50 using the same material.

[0071] The lower end of the venting pipe 70 can extend into the liquid storage space 220. The venting pipe 70 can draw back the aerosol generation matrix stored in the liquid storage space 220 through capillary force, thereby improving the utilization rate of the aerosol generation matrix and reducing the risk of leakage.

[0072] There is a certain distance between the lower end face of the venting pipe 70 and the bottom wall of the liquid storage space 220 to prevent the inlet of the venting pipe 70 from being blocked. Of course, this distance should not be too large, so as to allow as much aerosol generation matrix as possible to be drawn back into the liquid storage space 220.

[0073] The above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
