[0035] Please refer to Figures 1 to 8 As shown, the present invention discloses an atomization assembly 100 , which is used in an electronic atomization device (eg, an electronic cigarette). The atomization assembly 100 includes an outer tube 1 , an oil storage element 2 , a heating element 3 and an inner tube 4 .

[0036] In the illustrated embodiment of the present invention, the outer tube 1 is a glass outer tube, that is, the outer tube 1 is made of glass material.

[0037] The outer tube 1 is generally hollow cylindrical and includes an outer surface 11, an inner surface 12, and a first cavity 13 enclosed by the inner surface 12. The outer tube 1 includes a wall portion 10, wherein the outer surface 11 and the inner surface 12 are both located on the wall portion 10. In the illustrated embodiment of the present invention, the outer surface 11 and the inner surface 12 are both cylindrical. The wall portion 10 is further provided with a plurality of through-holes 14 extending through the outer surface 11 and the inner surface 12. In the illustrated embodiment of the present invention, the through-holes 14 are arranged in several rows along the axial direction of the outer tube 1. The through-holes 14 in each row are distributed circumferentially along the outer tube 1. In the illustrated embodiment of the present invention, the through-holes 14 are circular micropores. Of course, those skilled in the art will appreciate that the shape, opening position, and porosity of the through-holes 14 can be flexibly adjusted as needed to ensure the permeability of the liquid.

[0038] In the illustrated embodiment of the present invention, the diameter of each through hole 14 is D, wherein 10 microns ≤ D ≤ 30 microns.

[0039] Those skilled in the art will appreciate that, with the design of the outer tube 1 of the present invention in a non-atomizing heating scenario, the solution located in the outer circumference of the outer tube 1 is based on the microtube siphon effect, so that it is basically microfluidic pressure from the outside to the perforation 14, and the pressure difference of each perforation 14 is basically the same, thereby ensuring that the cold liquid does not flow back, does not leak inward to the steam duct and other related components, and no internal or external leakage pollution occurs, ensuring that the atomizing component 100 can participate in atomization without impurities in the heating state. In addition, with the design of the outer tube 1 of the present invention in an atomizing heating scenario, when the steam duct is in a state of artificially created large negative pressure difference (for example, smoking), based on the Brunei principle, the solution on the periphery of the outer tube 1 can be quickly filled into the oil storage element 2, which can ensure that there is sufficient solution supply during the atomizing heating period, reducing the occurrence of odor caused by dry burning.

[0040] The outer tube 1 of the present invention is made of glass (e.g., specialty glass), a material with a relatively mature manufacturing process and high temperature resistance up to 1000°C. The shape of the outer tube 1 is easily controllable, facilitating subsequent production and assembly. The perforations 14 can utilize TGV (Through Glass Via) technology for precise control.

[0041] The oil storage element 2 is housed in the first cavity 13 of the outer tube 1. In one embodiment of the present invention, the oil storage element 2 is oil storage cotton, such as a high-temperature resistant mesh-structured polymer fiber oil storage cotton. The oil storage element 2 is generally hollow cylindrical and defines a second cavity 23.

[0042] The heating element 3 is at least partially accommodated in the second cavity 23. The heating element 3 is configured to heat the liquid in the oil storage element 2 to atomize the liquid into a gaseous state.

[0043] In the illustrated embodiment of the present invention, the heating element 3 is a metal heating plate, which includes a main body 30, a first lead 31 connected to the main body 30, and a second lead 32 connected to the main body 30. The first lead 31 and the second lead 32 are respectively used to connect to the positive and negative poles of a power source to supply power to the heating element 3.

[0044] In the illustrated embodiment of the present invention, the heating element 3 is provided with a third cavity 33, and the inner tube 4 is at least partially accommodated in the third cavity 33. Specifically, in the illustrated embodiment of the present invention, the main body 30 is arranged in a 360° surrounding manner on the inner side of the oil storage element 2 and the outer side of the inner tube 4.

[0045] In the illustrated embodiment of the present invention, the main body 30 is provided with a plurality of first heating strips 301 extending axially along the heating element 3, and a plurality of second heating strips 302 extending circumferentially along the heating element 3. The second heating strips 302 connect adjacent first heating strips 301 to form a plurality of rectangular openings 303. In the illustrated embodiment of the present invention, adjacent openings 303 are staggered along the circumference of the heating element 3. The openings 303 are used to allow atomized, gaseous e-liquid to pass through.

[0046] The heating element 3 of the present invention can make the supply current flow through any conductive heating position of the heating element 3 substantially uniformly, so that the heating temperature of the heating element 3 remains substantially consistent, thereby making the atomization temperature substantially consistent.

[0047] The inner tube 4 is at least partially housed in the third cavity 33. In the illustrated embodiment of the present invention, both end faces of the inner tube 4 are flush with both end faces of the main body 30. Specifically, the inner tube 4 includes a first end face 41, a second end face 42 opposite to the first end face 41, a tube wall 43 located between the first end face 41 and the second end face 42, an air flow channel 40 extending axially through the first end face 41 and the second end face 42 of the inner tube 4, and a plurality of air flow holes 44 extending radially through the tube wall 43 of the inner tube 4. The air flow holes 44 are in communication with the air flow channel 40. The inner tube 4 is configured to allow atomized gas to flow from the air flow holes 44 to the air flow channel 40.

[0048] In the illustrated embodiment of the present invention, the plurality of air holes 44 include a first air hole 441, a second air hole 442 located on one side of the first air hole 441 along the axial direction of the inner tube 4, and a third air hole 443 located on the other side of the first air hole 441 along the axial direction of the inner tube 4. The length of the first air hole 441 along the axial direction of the inner tube 4 is greater than the length of the first air hole 441 along the circumferential direction of the inner tube 4.

[0049] The axial length of the second air flow hole 442 along the inner tube 4 is greater than the circumferential length of the second air flow hole 442 along the inner tube 4; and / or the axial length of the third air flow hole 443 along the inner tube 4 is greater than the circumferential length of the third air flow hole 443 along the inner tube 4.

[0050] In the illustrated embodiment of the present invention, there are several first air flow holes 441 distributed along the circumference of the inner tube 4, there are several second air flow holes 442 distributed along the circumference of the inner tube 4, and there are several third air flow holes 443 distributed along the circumference of the inner tube 4.

[0051] In the illustrated embodiment of the present invention, adjacent first air flow holes 441 and second air flow holes 442 are staggered along the axial direction of the inner tube 4; adjacent first air flow holes 441 and third air flow holes 443 are staggered along the axial direction of the inner tube 4; corresponding second air flow holes 442 and third air flow holes 443 are aligned along the axial direction of the inner tube 4.

[0052] In the illustrated embodiment of the present invention, the inner tube 4 is made of glass to withstand high temperatures. Furthermore, the glass inner tube facilitates control of the sizes of the first airflow holes 441, the second airflow holes 442, and the third airflow holes 443 through relatively sophisticated processes. The relatively large airflow holes 44 provided in the present invention facilitate smooth flow of atomized gas from the airflow holes 44 into the airflow channel 40, reducing the undesirable effects of trapped or insufficient steam during the atomization process.

[0053] The main body 30 of the heating element 3 is located between the oil storage element 2 and the inner tube 4. The heating element 3 can heat the oil storage element 2 to atomize the liquid into gas; when the gas passes through the air flow hole 44 and the air flow channel 40, the heating element 3 can also perform secondary heating, which is beneficial to improving the atomization effect.

[0054] The overall structure of the atomizing assembly 100 of the present invention adopts a modular radially surrounding combination method, which can meet the requirements of the automated operation process, reduce costs, and improve process efficiency.

The understanding of the present invention should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in the field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
