[0019] To make the objectives, technical solutions, and advantages of the disclosed embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0021] The electronic atomization device includes a battery module (not shown in the figure), an oil cup assembly (not shown in the figure), and an atomization assembly 100. The atomization assembly 100 and the oil cup assembly form an atomizer body in combination. The oil cup assembly contains e-liquid. The atomization assembly 100 is fixed in the middle of the oil cup. The atomization assembly 100 can heat and atomize the e-liquid to generate smoke. An integrated cotton is also filled on the outer peripheral side of the atomization assembly 100. The integrated cotton is a plant fiber with strong oil absorption ability. The e-liquid is locked in the integrated cotton, reducing the fluidity of the e-liquid and the risk of leakage of the atomizer.

[0022] The present disclosure provides an atomization assembly 100, which includes an atomization bracket 3 with a hollow interior, a liquid guiding member 2, and a heating element 1. The atomization bracket 3 is a cylindrical tube with a hollow interior. A plurality of liquid guiding holes 31 are provided at intervals along the outer peripheral side of the middle part of the atomization bracket 3. The liquid guiding member 2 is a hub for e-liquid transfer, and under capillary action, it transports the e-liquid on the integrated cotton to the heating element 1. The heating element 1 heats the e-liquid to generate aerosol for users to inhale. The heating element 1 includes a C-shaped sheet-like heating mesh 11, two pads 12, and two pins 13. The two pads 12 are distributed at both ends of the heating mesh 11. The two pins 13 are respectively fixed on the two pads 12. Each pin 13 extends outward in the direction towards the liquid guiding member 2 to form a bending portion 14. The bending portion 14 is in an inverted L shape, so that the bending portion 14 closely adheres to the top and the outer side wall of the liquid guiding member 2. The pins 13 clamp the liquid guiding member 2, making the liquid guiding member 2 and the heating element 1 fit without gaps, preventing problems such as burning of the liquid guiding member 2 or dry burning of the heating element 1 caused by insufficient fitting and resulting in gaps.

[0023] During assembly, first lay the flat mesh heating element 1 flat in the middle of the liquid guide 2, then use a cylindrical support rod to place it in the middle of the heating element 1, wrap the liquid guide 2 and the heating element 1 together with the support rod, then fold the pins 13 on the heating element 1 outward and fit the liquid guide 2, then insert it from the top of the atomizer bracket 3 into the atomizer bracket 3 to fix it, and then use pliers to cut off the excess liquid guide 2. Preferably, the liquid guide 2 and the atomizer bracket 3 form an interference fit, then the bent portion 14 located on the outer wall of the liquid guide 2 will also be pressed between the atomizer bracket 3 and the liquid guide 2, to achieve the fixation of the bent portion 14, to prevent the heating element 1 from being deformed due to pulling the pins 13 during the assembly process, to avoid affecting the processing of subsequent processes, and thus to ensure the overall quality of the electronic atomization device. In addition, there is no need to insert the atomizer base into the atomizer bracket 3 to fix the pins 13, which reduces costs, reduces assembly processes, facilitates manual operation, and is simple and convenient to use.

[0024] like Figure 1 As shown, the atomizer assembly 100 includes a heating element 1, a liquid guide 2 and an atomizer bracket 3 from the inside to the outside. The heating element 1 is wound into a cylindrical shape, and the liquid guide 2 wraps the heating element 1. When the liquid guide 2 is embedded in the atomizer bracket 3, the outer wall of the liquid guide 2 fits with the hole wall of the liquid guide hole 31, so that the smoke oil can quickly flow from the liquid guide hole 31 to the liquid guide 2. Pins 13 are respectively provided at both ends of the heating element 1, and a bending portion 14 is formed on the outer peripheral side of each pin 13. The bending portion 14 is a part of the pin 13, and the free end of the bending portion 14 can be connected to an external conductive medium, thereby providing power for the heating mesh 11. Specifically, the bending portion 14 includes a first connection segment 15 bent outward from the free end of the pin 13 and a second connection segment 16 bent downward from the free segment of the first connection segment 15. The second connection segment 16 is parallel to the central axis of the liquid guide 2. The second connection segment 16 is parallel to the outer side wall of the liquid guide 2, and the clamping force at various locations of the liquid guide 2 is consistent, ensuring the compactness of the clamping, which is conducive to the bending portion 14 of the pin 13 firmly clamping the liquid guide 2. Preferably, the spacing between the second connection segment 16 and the outer peripheral side of the heating element 1 is less than the thickness of the liquid guide 2.

[0025] Specifically, the first connecting section 15 is provided with a retaining portion 17 protruding toward the inner surface of the liquid guide, and the retaining portion 14 is embedded in the top of the liquid guide. The retaining portion 17 can be a protruding spike structure, which can fix the position of the bending portion 14, reducing the problem of core sticking caused by the deformation of the heating mesh 11 caused by pulling the pin 13 during subsequent assembly.

[0026] In one embodiment, see Figures 1-3A liquid guide groove 32 is provided on the side of the atomizer bracket 3 at a side opposite to the liquid guide hole 31, and a side ear 21 is provided on the side of the liquid guide member 2. The side ear 21 extends radially along the liquid guide groove 32. Specifically, the side ear 21 contacts the gas smoke oil to increase the liquid guide rate of the atomizer assembly 100, and prevent the heating element 1 from being stuck due to insufficient liquid supply.

[0027] like Figure 1 As shown, the C-shaped opening of the heating mesh 11 faces the liquid guide groove, and the bent portions 14 on the two pins 13 are symmetrically distributed on both sides of the side ears 21, so that the bent portions 14 of the two pins 13 are staggered by a certain width to avoid the two bent portions 14 being connected in series, prevent line interference, and facilitate installation.

[0028] In one embodiment, the liquid guide member 2 is formed by stacking and curling several layers of sheet-like cotton cloth. The cotton cloth has a good liquid guide rate due to its large porosity. The two ends of the liquid guide member 2 overlap to form side ears 21. Among them, the liquid guide member 2 is flax and / or non-woven fabric. Flax has better high temperature resistance than non-woven fabric, and non-woven fabric has a better liquid guide rate than flax; the liquid guide member 2 adopts a combination of flax and non-woven fabric, which has the characteristics of fast liquid guide and high temperature resistance.

[0029] Specifically, the inner layer of the liquid-conducting member 2 is linen and the outer layer is non-woven fabric. Specifically, the inner layer of the liquid-conducting member 2 in contact with the heating element needs to have good heat resistance, and the outer layer of the liquid-conducting member 2 in contact with the aerosol generating matrix needs to have a good liquid-conducting rate; the liquid-conducting member 2 adopts the distribution mode of the inner layer of linen and the outer layer of non-woven fabric, which, on the one hand, makes the liquid-conducting member 2 have a fast liquid-conducting rate, and on the other hand, the liquid-conducting member 2 can withstand the high temperature of the heating element to avoid core sticking.

[0030] The above are only specific embodiments of the present invention, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
