Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an aerosol generating device with high atomization efficiency. Background Art

[0002] At present, in the existing aerosol generating device, only one heating core can be installed in the atomization cavity of the atomization main body to heat the e-liquid. However, the heating area of a single heating core is small, and the heat generation amount and the e-liquid absorption amount are limited, resulting in a small amount of smoke generated by heating the e-liquid during use and a poor saturation of the smoke taste. Moreover, for the oil guiding holes in the atomization main body for guiding the e-liquid in the oil storage cavity into the heating core, the positions of the oil guiding holes are slightly higher than the bottom wall of the oil storage cavity. When the amount of e-liquid in the oil storage cavity is lower than the oil guiding holes, the use needs to be stopped. If continued to be used, dry burning will occur due to insufficient oil absorption by the heating core, resulting in the remaining e-liquid in the oil storage cavity not being consumed completely, causing low e-liquid utilization rate and short service life of the atomization main body.

[0024] In the present utility model, terms such as "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing and understanding the technology of the present utility model, rather than limiting that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present utility model.

[0025] As Figures 1-5 shown, the present utility model provides an aerosol generating device with high atomization efficiency, which includes a power supply main body 11 and an atomization main body 12 electrically connected to the power supply main body 11. The atomization main body 12 has an oil storage cavity 503 and an oil accumulation part corresponding to and communicating with the oil storage cavity 503. A mist passage 601 is formed in the oil storage cavity 503, and an atomization cavity 703 communicating with the mist passage 601 is formed in the oil accumulation part. The mist passage 601 and the atomization cavity 703 are isolated from the oil storage cavity 503 and the oil accumulation part. At least two heating cores 8 are provided in the atomization cavity 703, and a conduction part corresponding to the oil accumulation part is provided on the cavity wall corresponding to the atomization cavity 703. Both ends of each heating core 8 extend into the oil accumulation part through the conduction part to absorb e-liquid and heat and atomize it. It should be noted that by designing multiple heating cores 8 in the atomization cavity 703 and designing an oil accumulation part for collecting the remaining e-liquid on the bottom wall of the oil storage cavity 503, the problems of the existing aerosol generating device are solved, such as the small heat generation of the heating core 8 resulting in a small amount of smoke generated by atomizing the e-liquid and poor taste saturation, and the low utilization rate of e-liquid because the e-liquid in the oil storage cavity 503 cannot be completely consumed.

[0026] In some embodiments, the oil storage cavity 503 has a corresponding cavity bottom wall, and the oil accumulation part is arranged on the cavity bottom wall of the oil storage cavity 503, and the volume of the oil accumulation part is smaller than that of the oil storage cavity 503. Among them, the oil accumulation part is arranged on the cavity bottom wall of the oil storage cavity 503. After the e-liquid is injected into the oil storage cavity 503, it can enter the oil accumulation part, and then the e-liquid is introduced into the heating core 8 through both ends of the heating core 8. After being powered on, the heating core 8 generates heat to heat the e-liquid to produce smoke. Among them, the volume of the oil accumulation part is smaller than that of the oil storage cavity 503. When the e-liquid in the oil storage cavity 503 is consumed until it is almost at the bottom, the remaining e-liquid can all flow into the oil accumulation part. Since the volume of the oil accumulation part is small and the e-liquid level is high, both ends of the heating core 8 will be completely immersed in the e-liquid and absorb all the e-liquid, and heat it to produce smoke.

[0027] In some embodiments, the oil accumulation part is formed by the gap space 904 and / or the groove 901; the conduction part is formed by the notch 701 and / or the through hole. In this embodiment, the oil accumulation part preferably adopts the gap space 904, and the small volume can raise the e-liquid level of the remaining e-liquid; in this embodiment, the conduction part preferably adopts the notch 701, which is convenient for design and for both ends of the heating core 8 to extend out of the atomization cavity 703 into the oil accumulation part.

[0028] In some embodiments, a gas guiding channel 903 is further arranged on the cavity bottom wall of the oil storage cavity 503. The gas guiding channel 903 corresponds to and communicates with the atomization cavity 703. A mist discharging channel 505 communicating with the mist channel 601 is further formed in the oil storage cavity 503. The mist discharging channel 505 is also isolated from the oil storage cavity 503 and the oil accumulation part. It should be noted that the gas guiding channel 903 is used to guide gas into the atomization cavity 703, and then drive the smoke generated by heating the e-liquid by the heating core 8 into the mist channel 601. The mist discharging channel 505 is used to discharge the smoke. Among them, the mist discharging channel 505 is also isolated from the oil storage cavity 503 and the oil accumulation part to prevent the e-liquid in the oil storage cavity 503 from entering the mist discharging channel 505 and then flowing out of the atomization main body 12 to cause oil leakage.

[0029] In some embodiments, an air inlet hole 104 communicating with the gas guiding channel 903 is arranged on the power supply main body 11, and an electronic control component 110 for supplying power to each heating core 8 is arranged in the power supply main body 11. Among them, the air inlet hole 104 is used for the external air flow to enter during smoking, and then is introduced into the atomization cavity 703 through the gas guiding channel 903. The electronic control component 110 is used to power on the heating core 8 to make it generate heat, and at the same time control the heat generation amount of the heating core 8.

The upper end of the mist pipe 6 is inserted into the exhaust pipe 504, so that the mist passage 601 is communicated with the exhaust mist passage 505. The space between the outer walls of the mist pipe 6 and the exhaust pipe 504 and the inner wall of the oil storage chamber 5 forms an oil storage cavity 503. The top wall 501 of the oil storage chamber 5 is provided with a mist outlet 502 communicated with the exhaust mist passage 505. Among them, the oil storage cavity 503 is used for storing e-liquid. The upper end of the mist pipe 6 is inserted into the exhaust pipe 504 and positioned in the oil storage cavity 503. The mist pipe 6 and the exhaust pipe 504 are used to isolate the e-liquid in the oil storage cavity 503. After the air flow enters from the air inlet hole 104, it can enter the atomization cavity 703 through the air guide passage 903, and then drive the smoke generated by the heating of the e-liquid by the heating core 8 into the mist passage 601, and then sequentially discharge from the exhaust mist passage 505 and the mist outlet 502 out of the atomization body 12.

The annular surrounding wall 902 is used to connect and position the atomization cover 7. The gap space 904 as the oil accumulation part is used to collect a small amount of remaining e-liquid in the oil storage cavity 503, and then supply it to the heating core 8 for heating and atomization. In some other embodiments, the oil accumulation part can also be formed by the groove 901. A small amount of remaining e-liquid in the oil storage cavity 503 can flow into the groove 901, and then be supplied to the heating core 8 for heating and atomization.
