Embodiments of the present invention

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the related drawings. The preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided.

It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions used herein are for the purpose of illustration only and do not represent the only embodiment.

As shown in FIGS. 1 to 24 , which are some embodiments of the atomization assembly 10 of the present invention, the atomization assembly 10 includes a liquid guide 12 and a heating body 14 installed on the liquid guide 12 . The smoke liquid is sucked through the guiding liquid 12 , and the smoke liquid adsorbed in the guiding liquid 12 is heated and atomized by the heating element 14 . The atomizing assembly 10 can be used in an electronic cigarette to heat and atomize the smoke liquid for the user to smoke. It can be understood that the atomizing assembly 10 can also be adjusted to be used on corresponding different products according to the requirements of the actual application.

As shown in the figure, in some embodiments, the liquid conducting liquid 12 can be roughly in the shape of a cuboid. Of course, its shape can also be made into different shapes according to different requirements, such as cylindrical shape, pyramid shape, irregular shape and so on.

The liquid guide 12 includes a liquid suction surface 121 and an atomization surface 122 which are arranged opposite to each other. The liquid suction surface 121 is used to communicate with the liquid storage chamber of the electronic cigarette, so as to draw the smoke liquid in the liquid storage chamber into the guiding liquid 12 . The smoke liquid in the guiding liquid 12 is heated and atomized by the heating element 14 , and then escapes through the atomizing surface 122 .

As shown in FIG. 3 , the liquid absorbing surface 121 can be formed indentation inside the main body of the liquid guide 12 , thereby increasing the area of the liquid absorbing surface 121 , thereby better absorbing the smoke liquid. The atomizing surface 122 is disposed on the other side of the liquid-conducting surface 12, and is substantially parallel to the liquid-absorbing surface 121, so as to avoid interference with the liquid-absorbing surface 121 and affect the effect of smoke generation. It can be understood that the shapes and positions of the liquid absorbing surface 121 and the atomizing surface 122 can be adjusted according to actual needs without limitation.

In some embodiments, the conductive liquid 12 may be made of hard capillary structures such as porous ceramics, porous glass ceramics, porous glass, and the like. The heating element 14 can be made of various metals such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, and metal titanium.

When the liquid conducting liquid 12 is a sintered structure, the heating element 14 can be integrally sintered and formed with the conducting liquid 12 . For example, when the conductive liquid 12 is a porous ceramic, the body of the conductive liquid 12 can be formed first with kaolin mud, and then the heating element 14 is embedded in the proper position of the body, and then the body is dried and sintered.

Wherein, the heating element 14 may be directly a metal sheet, or may be a film-coated heating sheet or a heating sheet of other forms. When using a metal sheet, it can be directly embedded in the embryo body for sintering and forming; when using a coated heating plate, the organic diaphragm with a metal heating plate is embedded in the embryo body. During the sintering process, the organic diaphragm will be burned. The metal heating plate left behind is closely combined with the embryo body to form a whole.

The design of the heating element 14 needs to refer to the thermal effect of the resistor, that is, when the current passes through the resistor, the current does work and consumes electric energy to generate heat. The resistance of the conductor is mainly affected by two factors when the material is determined: 1. The cross-sectional area of the conductor, the smaller the cross-sectional area, the greater the resistance, and the larger the cross-sectional area, the smaller the resistance. 2. The length of the conductor, the longer the length, the greater the resistance.

The cross-sectional area of the conductor is mainly affected by the thickness and width of the heating sheet. Under the condition of constant cross-sectional area, the thinner the thickness, the wider the width. Theoretically, the thinner the heating element 14, the larger the surface area of the heating element 14, and the larger and more uniform the distribution on the ceramic surface. However, when the thickness is too small, the depth of the heating element 14 embedded in the liquid conducting liquid 12 is relatively low, and the heating element 14 and the liquid conducting liquid 12 are prone to detachment. The problem.

In some embodiments, the heating body 14 includes at least one lengthwise sheet-shaped heating section 141 . Under the condition of satisfying the mechanical properties, the width d of the sheet-shaped heating section 141 can be 0.05-0.25 mm, and the thickness h can be 0.008-0.1 mm, which can greatly reduce the internal heat accumulation, and the atomization efficiency is higher. It can be understood that when the width is too wide, the heat starts slowly, and the heating body 14 reaches the atomization temperature slowly. If the width is wide, the heat dissipation of the heating body 14 itself is also slow. In actual use, the taste needs to be good, and it needs to be thinner The line width of the heating element 14, in some embodiments, the width of the heating segment does not exceed 0.2mm.

Further, in some embodiments, several bosses 123 higher than the atomization surface 122 are provided on the liquid guide 12 . The plurality of bosses 123 are disposed adjacent to the heating body 14 and/or partially cover the heating body 14; at least part of the atomizing surface 122 adjacent to the heating body 14 is flush with the top surface of the heating body 14 and/or lower than the heating body 14 on the top surface. By arranging the bosses 123 adjacent to the heating body 14 and/or partially covering the heating body 14, the liquid supply effect can be in a better state; The top surface is lower than the top surface of the heating body 14 and/or lower than the top surface of the heating body 14, thereby avoiding the structure of the small groove formed in the prior art, avoiding the accumulation of liquid covering the heating body 14 and being unable to discharge the atomized steam liquid splashing, leakage and other defects caused by it.

As shown in FIGS. 2 and 3 , the boss 123 includes a boss section 1231 that is close to or close to one side edge of the sheet-shaped heating segment 141 and is arranged along the longitudinal direction; The top surface of the side atomizing surface 122 is flush with the top surface of the sheet-shaped heating segment 141 . The height difference H between the top surface of the boss section 1231 and the top surface of the atomizing surface 122 is 0.1-1 mm. The design of this height is related to factors such as the amount of atomization. If the design is too high, it will easily form a small tank of liquid to cover the heating element 14. If the design is too high, it will prevent the airflow from passing through the surface of the heating area and spray the high-temperature atomized steam. If it is brought out, it is easy to accumulate heat; if the design is too low, there will be problems that the boss 123 is too small, the stored liquid is too small, and the effect is not obvious.

It can be understood that the top surface of the atomizing surface 122 on the side of the sheet-shaped heating segment 141 opposite to the boss segment 1231 may also be lower than the top surface of the sheet-shaped heating segment 141 .

By disposing the boss section 1231 on one side of the sheet-shaped heating section 141, the problem of frying oil is avoided, and at the same time, the boss section 1231 can also play the role of storing smoke liquid. In addition, the heat of the sheet-shaped heating section 141 can also be radiated to the boss section 1231. Compared with the planar structure, the boss section 1231 has a larger surface area, which is equivalent to increasing the area of the atomizing surface 122, making the atomization effect better. .

The two ends of the heating body 14 are electrodes respectively, so as to connect the power supply to generate heat.

The boss section 1231 is disposed between the two sheet-shaped heating sections 141, and the number of the boss sections 1231 can be adjusted as required. In addition, the boss 123 includes a connecting boss section 12321 disposed close to or close to one side of the connecting section 142, so as to match the shape of the heating body 14, thereby optimizing the atomization effect.

Further, the two sheet-shaped heating segments 141 and the boss segment 1231 provided between them form a group of heating structures together, and the atomization assembly 10 can be provided with several groups of heating structures that are side by side and/or symmetrical, and the discharge positions can be arranged according to actual conditions. Adjustment is required.

At least two sheet-like heating segments 141 are arranged between the adjacent boss segments 1231, and the distance D between the edges of the two adjacent boss segments 1231 is greater than 0.2 mm, thereby avoiding the capillary phenomenon in the heating body. Liquid accumulation is formed above 14, avoiding the risk of frying oil.

In this embodiment, since the bosses 123 are arranged in parallel at the middle position of the liquid guide 12, at least one airflow channel 124 is formed between the bosses 123, and the airflow channel 124 penetrates to the edge of the liquid guide 12 to avoid blocking the air flow, and the convex The height of the stage 123 can be appropriately increased.

In some embodiments, it is another embodiment in which the boss section 1231 and the sheet-shaped heating section 141 cooperate. As shown in FIGS. 4-6 , a first Gap 125 ; the height of the top surface of the atomizing surface 122 corresponding to the first gap 125 is flush with and/or lower than the top surface of the sheet-shaped heating segment 141 . In this embodiment, the distance between the adjacent sheet-shaped heating segments 141 is relatively large, so a boss segment 1231 can be provided between the adjacent sheet-shaped heating segments 141, so that the Store more e-liquid, which in turn can increase the amount of atomization.

As shown in FIGS. 7-9, the boss section 1231 includes extending in the direction of the sheet-shaped heating section 141 to cover part of the The cover portion 1233 above the sheet-shaped heating segment 141 . The cover part 1233 is attached to the top surface of the sheet-shaped heating segment 141 , which increases the contact area between the heating element 14 and the boss 123 , so that the boss segment 1231 can be directly heated and atomized by the sheet-shaped heating segment 141 . It can be understood that a second gap (not shown) may also be left between the cover portion 1233 and the top surface of the sheet-shaped heating segment 141, and the heat generated by the sheet-shaped heating segment 141 can also be radiated to the boss segment 1231.

Further, the boss 123 is arranged on the outer side of the heating body 14, and the shape is basically the same as the shape of the heating body 14. At the same time, an airflow channel 124 is formed in the middle of the liquid conducting body 12 to the edge, so as to facilitate the heating body 14 to heat the mist. Emission of the melted smoke.
