Detailed ways

Please refer to FIG. 1 to FIG. 12, which show the specific structures of various embodiments of the present invention. The atomizing device of the present invention can be applied to electronic cigarettes, medical atomizing devices and other products; in this article, an electronic cigarette is taken as an example for detailed description.

An atomization device that improves atomization effect and prevents liquid leakage, comprising a liquid storage chamber 1, an atomization cup 2, an air inlet 3 and an air outlet pipe 4, wherein: the atomization cup 2 has an upper end opening, and the outlet The air pipe 4 extends into the atomizing cup 2 from the opening at the upper end and maintains a gap with the inner bottom surface of the atomizing cup 2, and an air inlet channel 5 is formed between the outer periphery of the air outlet pipe 4 and the inner wall surface of the atomizing cup 2; the liquid storage The liquid in the cavity 1 enters the atomizing cup 2 and is heated and atomized into an atomized substance. Usually, the liquid in the liquid storage cavity 1 enters the atomizing cup 2 through an infiltrating oil guide. The infiltrating oil guide can refer to cotton rope, fiber, foamed ceramics, etc.; or, the liquid in the liquid storage chamber 1 enters the atomizing cup 2 by means of injection or the like.

The outside air enters the atomizing cup 2 through the air inlet 3, the upper end opening of the atomizing cup 2, and the air inlet channel 5 in turn, mixes with the atomized matter, and is discharged from the air outlet pipe 4. In this way, the gas enters downward from the surrounding of the atomizing cup, mixes with the atomized material in the area below the air outlet pipe 4, merges into a stream of air and then enters from the lower end opening of the air outlet pipe 4, and is discharged upward through the air outlet pipe 4; atomization The cup can accommodate and absorb excess exuded liquid. Since the airflow does not form a convection trend of up and down, it avoids the phenomenon that the liquid is sucked into the user's mouth or spilled out of the electronic cigarette. Preferably, on the air inlet side, it also means that before the gas enters the atomizing cup 2, a cavity 193 is provided in the atomizing device at the entrance of the air inlet channel 5. After the gas enters from the outside through the air inlet 3, it passes through The cavity 193 , the upper end opening of the atomizing cup 2 and the air inlet channel 5 enter the atomizing cup 2 . The cavity 193 is in a semi-closed state. When there is excess liquid in the atomizing cup 2 and the atomizing device is turned upside down, the cavity 193 can accommodate the liquid overflowing in the atomizing cup 2. Therefore, the suction cup 2 can be placed in the cavity 193. Liquid material piece 194 (eg, oil absorbing material piece), as shown in FIG. 12 .

As shown in FIG. 4 , the cross-sectional area of the air inlet passage 5 is smaller than the cross-sectional area under the corresponding air outlet pipe 4 in the atomizing cup 2 . Here, the length and shape of the cannula 17 can be freely set by sheathing the sleeve 17 on the outer circumference of the trachea 4. For example, the upper end of the cannula 17 is set to a smaller section to fit the trachea 4, and the cannula The lower end of 17 is set as a larger section to provide a larger confluence port and to form a narrower intake passage 5 . The air intake channel 5 can be set at a distance of about 0.3 to 1.0 mm to speed up the air flow. When the gas reaches the wider area below the air outlet pipe 4 from the narrow air intake channel 5, the air flow speed changes sharply to form a vortex, which is fully compatible with the atomized material. Mixing, thereby achieving the purpose of uniform atomization and soft taste. At the same time, the formed eddy current can fully take away the atomized material in time, avoid the retention of the atomized material and affect the subsequent atomization, and effectively speed up the atomization speed. Since the air inlet channel 5 is relatively narrow, it is easy to form a capillary phenomenon. When there is excess liquid seeping out, it can absorb or guide the excess liquid into the cavity 193 in the suction nozzle shell 192 to further prevent the liquid from being sucked into the user. The phenomenon of oral or external spillage of electronic cigarettes. In order to improve the taste, a filter material 171 may be provided in the air outlet pipe 4 or the sleeve 17 to absorb larger particles in the atomized gas, as shown in FIG. 12 .

Usually, the top or side of the atomizing cup 2 has an air inlet channel 5, and the air outlet pipe 4 is connected to the top of the atomizing cup 2; Below the outlet pipe 4. As shown in Figures 1 to 8, it shows the design situation that the gas outlet pipe 4 extends into the atomizing cup, and the gas enters from the top of the atomizing cup 2. However, as shown in FIG. 9 to FIG. 12 , it shows the design situation that the upper end of the atomizing cup 2 extends into the gas outlet pipe 4 , and the gas enters from the side of the atomizing cup 2 . Of course, in the actual design, it is not limited to the several situations shown in the figure, and its structure is slightly changed, which also belongs to the same technical solution of the present invention, which is limited by space and will not be repeated here.

As shown in FIG. 3 and FIG. 4 , the atomizing cup 2 has a through hole 6 for the liquid to enter the atomizing cup 2 from the liquid storage chamber 1 , and the atomizing cup 2 extends with a preheating part 7 , which is A preheating channel 8 that communicates with the through hole 6 is formed in the hot part 7 . The setting of the preheating channel 8 effectively enhances the fluidity of the e-liquid. The atomizing cup 2 has a bottom wall and a peripheral side wall. Usually, a through hole 6 is provided on the bottom wall, and the preheating part 7 is a cylindrical part extending downward from the bottom wall, such as a cylindrical part. Preferably, the atomizing cup 2 is a heating cup body, and the heating cup body is used for atomization, which effectively increases the atomization area and enhances the atomization effect; the thickness of the heating cup can be designed to be thinner, and the heat conduction is better. Fast, can greatly shorten the preheating time after power-on, compared with the traditional heating wire, the heating area is increased by 300%-400% under the same volume, the heating is more uniform, the atomization is more uniform and sufficient, and, There will be no excessive smoke temperature and hot mouth phenomenon, and it also avoids the explosion sound when the liquid is vaporized due to uneven temperature during atomization.

In the actual design and production, the wall of the atomizing cup 2 can be designed to have a thermally conductive layer 9, an insulating layer 10, a heating layer 11, a thermal insulation layer 12, and a thermally conductive layer 9 arranged in sequence from the inside to the outside. The heat is balanced to achieve the effect of soft atomization. The setting of the insulating layer 10 serves the purpose of insulating the heating layer 11 and the heat-conducting layer 9. The heating layer 11 provides the heat required for atomization, and the insulating layer 12 effectively avoids the waste of heat caused by heat dissipation. adverse effects on other parts of the product. Preferably, a protective layer 18 can also be provided on the inner side of the heat-conducting layer to prevent potentially harmful substances from the atomizing cup 2 from entering the atomizing cavity of the lower region of the air outlet pipe 4; a heating element can also be provided on the inner side of the atomizing cup 2 Alternatively, a heating element may also be provided on the outer side of the atomizing cup 2 .

For the heating layer 11 and the heating element, a heating circuit can be selected, and the heating circuit is attached to the atomizing cup 2 by printing or etching. The heating circuit is used, and there is no need to consider the conductivity when conventional resistance heating is used. In terms of performance, there is a wider range in the selection of materials. Materials can be selected according to the actual requirements of the product to improve safety, prolong service life, etc., and can also choose materials according to the use environment, such as medical-grade materials, high-adsorption materials, high-strength materials, etc. And, when atomizing devices with different powers need to be realized, since the heating area of the heating cup has been expanded by more than 3-4 times, it is only necessary to change the power of the resistance of the high-speed heating circuit to meet different power requirements. In this way, the product can be The size is standardized, and there is no need to design additional atomizing cups of different sizes, which reduces the cost of mold opening and parts.

Through the setting of the oil lock plate 13, the thickness of the oil guide member can be effectively controlled to avoid overflow and outflow caused by the contact between the oil guide member and the air outlet pipe 4, and the oil lock plate 13 and the bottom wall of the atomizing cup 2 are kept small enough The distance can realize the capillary phenomenon and achieve the purpose of locking oil. Here, the oil lock plate 13 is cup-shaped and also has a bottom wall and a peripheral side wall. The oil lock plate 13 is installed in the atomizing cup 2, and the peripheral side wall of the oil lock plate 13 is limited by the atomization. The inner side of the peripheral side wall of the cup 2 , which corresponds to the intake passage 5 , is formed by the peripheral side wall of the oil lock plate 13 and the outer side wall of the sleeve 17 .

The oil lock plate 13 can have various structural forms, for example: the oil lock plate 13 can be a heat-conducting plate, which is made of a heat-conducting material, which can absorb the heat of the atomized material and avoid burning the mouth; It is set as a heating resistor or a heating resistor is arranged on the oil lock plate 13, so that the oil lock plate 13 can have a heating function in addition to the oil locking function, so as to increase the heating power and heating area. If the oil lock plate 13 has a heating function, an additional oil guide member can also be optionally provided above the oil lock plate 13 . When only the oil lock plate 13 is used for heating, the atomizing cup 2 can also be made of a material with better thermal conductivity, so that the atomizing cup 2 can absorb heat to the atomized gas and play the role of cooling the atomized gas to avoid the occurrence of The smoke temperature is too high and the mouth is hot.

Therefore, when actually designing the product, the heating of the atomizing device can be heated by the atomizing cup 2 and/or the oil locking plate 13 . Generally speaking, if a single atomizing cup 2 is heated, the oil locking plate 13 preferably has good thermal conductivity; if the single oil locking plate 13 is heated, it is preferred that the atomizing cup 2 has good thermal conductivity; if the atomizing cup 2 If the oil lock plate 13 has a heating function at the same time, it is important to consider double heating to improve the atomization efficiency and atomization effect, and other methods can also be used to avoid excessive smoke temperature.
