The present invention provides an atomising device 100 which is capable of storing an aerosol generating substrate and of thermally atomising the aerosol generating substrate to form an aerosol for consumption by a user.
The atomizing device 100 includes a housing 101, and a heating assembly 102 disposed within the housing. The housing 101 is provided with a receiving cavity 1011 for storing the aerosol generating substrate, and the receiving cavity 1011 is communicated with an outer surface (oil guiding surface 1021) of the heating element 102, so that the aerosol generating substrate in the receiving cavity 1011 can flow to the oil guiding surface 1021.
An air inlet hole 1012 is formed in one end of the shell 101, a suction nozzle 1013 is arranged at the other end of the shell 101, an atomization channel 1014 is further arranged in the shell 101, one end of the atomization channel 1014 is communicated with the outside of the shell 101, the other end of the atomization channel is communicated with the air inlet hole 1012, and the air inlet hole 1012 is communicated with the outside of the shell 101. When the heating assembly 102 generates the aerosol, the aerosol is emitted into the nebulizing channel 1014, and the user can suck the suction nozzle 1013 with his mouth so that the outside air enters the nebulizing channel 1014 through the air inlet hole 1012, and the air flow is mixed with the aerosol in the nebulizing channel 1014 and inhaled by the user through the other end.
The accommodating cavity 1011 is disposed above the heating element 102, and the accommodating cavity 1011 is directly connected to the oil guiding surface 1021 of the heating element or connected thereto through an intermediate oil path. When the aerosol generating substrate is stored in the containing cavity, under the gravity action of the aerosol generating substrate, the aerosol generating substrate in the containing cavity directly flows to the oil guide surface 1021, then enters the heating assembly 102 from the oil guide surface 1021, and finally flows to the side of the heating assembly 102 opposite to the oil guide surface 1021, and the heating assembly 102 heats and atomizes the permeated aerosol generating substrate into aerosol for a user to suck.
It is emphasized that the aerosol-generating substrate is able to penetrate rapidly as it flows from the oil-guiding surface 1021 to the other side of the heating element, which is beneficial for improved atomization efficiency, while the aerosol-generating substrate is able to be confined to the column and is less prone to leakage.
Referring to fig. 1 and 2, the heating assembly 102 includes an oil guide body 1, a heating body 2, and two electrode rods 3, one side of the heating body 2 is connected to the oil guide body 1, the other side of the heating body 2 is connected to the two electrode rods 3, and one ends of the two electrode rods 3 away from the heating body 2 are exposed outside the case 101.
The surface of one side of the oil guide body 1, which is back to the heating body 2, is the oil guide surface 1021, and the oil guide surface 1021 is communicated with the accommodating cavity 1011 and is used for contacting the aerosol generating substrate. When the shell 101 is connected with a power supply host, the two electrode rods 3 can be respectively connected with the anode and the cathode of the power supply host to supply power to the heating element 2, so that the heating element 2 can heat and atomize aerosol generating substrates permeated by the oil guide body 1 into aerosol.
The oil guide body 1 of the embodiment shown in fig. 3 comprises an oil guide layer 11, an intermediate layer 12 and an oil locking layer 13 which are sequentially stacked; the oil guide layer 11, the middle layer 12 and the oil lock layer 13 are respectively provided with a first oil guide hole 111, a second oil guide hole 121 and a third oil guide hole 131, the aperture of the first oil guide hole 111, the aperture of the second oil guide hole 121 and the aperture of the third oil guide hole 131 are sequentially reduced, the first oil guide hole 111, the second oil guide hole 121 and the third oil guide hole 131 are sequentially communicated, and the first oil guide hole 111 is communicated with the outside of the oil guide body 1.
It is understood that the oil guiding surface 1021 is the surface of the oil guiding layer 11 facing away from the middle layer 12. The heating element 2 is arranged on one side of the oil locking layer 13 back to the middle layer 12, and the heating element 2 is communicated with the third oil guide hole 131. The heating element 2 is used to heat and atomize the aerosol-generating substrate oozed from the third oil guide hole 131 to form aerosol.
The aerosol generating substrate directly contacts the oil guide surface 1021, the aerosol generating substrate sequentially flows through the first oil guide hole 111, the second oil guide hole 121 and the third oil guide hole 131 to the heating element 2 under the action of gravity of the aerosol generating substrate, and the heating element 2 heats and atomizes the aerosol generating substrate. Because the aperture of the first oil guide hole 111, the aperture of the second oil guide hole 121 and the aperture of the third oil guide hole 131 are sequentially decreased, the aerosol generating substrate is not easy to leak in the process of flowing to the heating element 2, meanwhile, the aerosol generating substrate can fully flow onto the heating element 2, the heating element is not easy to dry and burn, and the aerosol generated by heating and atomizing the aerosol generating substrate has good taste.
Specifically, in the embodiment, when the user uses the atomizing device 100, after the aerosol-generating substrate in the accommodating cavity 1011 flows into the oil guide surface 1021 under the action of gravity, the aerosol-generating substrate may diffuse and permeate to the intermediate layer 12 along the first oil guide hole 111 of the oil guide layer 11, because the aperture of the second oil guide hole 121 of the intermediate layer 12 is smaller than that of the first oil guide hole 111, and the aperture of the second oil guide hole 121 is larger than that of the third oil guide hole 131 of the oil lock layer 13, the intermediate layer 12 plays a role in transmitting the aerosol-generating substrate from the oil guide layer 11 to the oil lock layer 13, and also plays a certain role in storing oil, locking oil and buffering oil. After the aerosol generating substrate enters the oil locking layer 13 from the second oil guiding hole 121 of the middle layer 12, the aerosol generating substrate is locked by the capillary force of the third oil guiding hole 131 to prevent the aerosol generating substrate from flowing back or overflowing, and meanwhile, compared with the traditional method that the third oil guiding hole 131 on the oil locking layer 13 only depends on the penetration of ceramics, the aerosol generating substrate can flow to the heating element 2 more quickly to be heated and atomized by the heating element 2 to form aerosol for a user to suck.
The oil conducting layer 11, the middle layer 12 and the oil locking layer 13 can be single-layer structural layers or multi-layer structural layers.
Referring to fig. 3, the oil guiding layer 11, the intermediate layer 12 and the oil locking layer 13 of the embodiment shown in fig. 3 have only one oil guiding hole, so the oil guiding layer 11, the intermediate layer 12 and the oil locking layer 13 are all single-layer structures.
Referring to fig. 4, the oil-guiding layer 11 of the embodiment shown in fig. 4 is a multi-layered structure. The first oil guide hole 111 of the oil guide layer 11 includes a first through hole 1111 and a second through hole 1112 which are communicated with each other, and the aperture of the first through hole 1111 is larger than the aperture of the second through hole 1112, and the aperture of the first through hole 1111 and the aperture of the second through hole 1112 are both larger than the aperture of the second oil guide hole 121. The first through hole 1111 communicates with the outside air, and the second through hole 1112 communicates with the second oil guide hole 121.
It is understood that in other embodiments, the number of through holes included in the oil guiding layer 11 may also be three or more, the arrangement order of the through holes in each layer is not limited, and the aperture of each through hole is larger than that of the second oil guiding hole 121.
It will be appreciated that the intermediate layer 12 and the oil-lock layer 13 may be provided with a multi-layer through-hole structure as in the oil-guiding layer 11, which is advantageous for more efficient delivery and oil-locking of the aerosol-generating substrate.
Because the oil guide body 1 includes the oil guide layer 11, the intermediate layer 12 and the oil locking layer 13 which are sequentially stacked, and the oil guide holes 140 on the oil guide layer 11, the intermediate layer 12 and the oil locking layer 13 are set to have the aperture which is sequentially reduced according to the different functions of the oil guide layer 11, the intermediate layer 12 and the oil locking layer 13. In order to better realize the oil guiding and locking functions of the oil guiding body 1, certain limits can be made on the hole diameters of the oil guiding holes on the oil guiding layer 11, the middle layer 12 and the oil locking layer 13.
In one embodiment, the first oil guide hole 111 of the oil guide layer 11 may be set to have a pore size of 40 micrometers or more and 50 micrometers or less; the second oil guide hole 121 of the intermediate layer 12 may be set to have a pore size greater than 15 micrometers (e.g., 16 micrometers) and smaller than 40 micrometers (e.g., 39 micrometers); the third oil guide hole 131 of the oil lock layer 13 may have a hole diameter set to be greater than or equal to 5 micrometers and less than or equal to 15 micrometers.

The extending direction of the fourth auxiliary oil hole 113, the extending direction of the first auxiliary oil hole 112 and the extending direction of the first oil guide hole 111 are perpendicular to each other, and it can be understood that the extending direction of the fourth auxiliary oil hole 113, the extending direction of the first auxiliary oil hole 112 and the extending direction of the first oil guide hole 111 are respectively arranged along the extending directions of the X-axis, the Y-axis and the Z-axis in the coordinate system of fig. 5. In other embodiments, the extending direction of the fourth auxiliary oil hole 113, the extending direction of the first auxiliary oil hole 112, and the extending direction of the first oil guide hole 111 may also be at other angles, for example, 45 ° or 60 °, which is not limited herein.
Neither the first auxiliary oil hole 112 nor the fourth auxiliary oil hole 113 penetrates the oil guide layer 11 to prevent the aerosol-generating substrate from leaking out from the side of the oil guide layer 11. It should be noted that in the embodiment shown in fig. 5, a part is cut at both right-angled edges of the oil guide layer 11 to clearly show the first auxiliary oil hole 112 and the fourth auxiliary oil hole 113.
Referring to fig. 6, the heat generating body 2 includes a first electrode plate 21, a second electrode plate 22 and a heat generating member 23, and both ends of the heat generating member 23 are connected to the first electrode plate 21 and the second electrode plate 22, respectively. The first electrode plate 21 and the second electrode plate 22 are respectively used for connecting the ends of the two electrode rods 3, so as to be electrically connected with the positive electrode and the negative electrode of an external host power supply to supply power for the heat generation of the heat generating member 23. When the heat generating member 23 generates heat, the aerosol generating substrate can be heated and atomized into aerosol by the high temperature generated by the heat generating member 23.
