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 "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

The present utility model provides an aerosolization device 100, the aerosolization device 100 being capable of storing an aerosol-generating substrate and being capable of heating and aerosolizing the aerosol-generating substrate to form an aerosol for inhalation 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 chamber 1011 for storing an aerosol-generating substrate, and the receiving chamber 1011 communicates with an outer surface (oil guiding surface 1021) of the heating unit 102 so that the aerosol-generating substrate in the receiving chamber 1011 can flow to the oil guiding surface 1021.

An air inlet 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 1014 is communicated with the air inlet 1012, and the air inlet 1012 is communicated with the outside of the shell 101. After the heating assembly 102 generates the aerosol, the aerosol may be dispersed in the nebulizing channel 1014, and the user may suck the suction nozzle 1013 with his/her mouth so that the external air enters the nebulizing channel 1014 through the air inlet 1012, and the air flow is mixed with the aerosol of the nebulizing channel 1014 and then inhaled by the user through the other end.

The accommodating chamber 1011 is disposed above the heating assembly 102, and the accommodating chamber 1011 is directly connected to the oil guiding surface 1021 of the heating assembly or connected to the heating assembly through an intermediate oil path. When the aerosol generating substrate is stored in the accommodating cavity, the aerosol generating substrate in the accommodating cavity directly flows to the oil guiding surface 1021 under the gravity action of the aerosol generating substrate, then enters the heating component 102 from the oil guiding surface 1021, finally flows to the side of the heating component 102 back to the oil guiding surface 1021, and the heating component 102 heats and atomizes the permeated aerosol generating substrate into aerosol for a user to inhale.

It should be emphasized that the aerosol generating substrate can quickly permeate during the process of flowing from the oil guiding surface 1021 to the other side of the heating component, which is beneficial to improving the atomization efficiency, and meanwhile, the aerosol generating substrate can be limited by the column, so that liquid leakage is not easy to occur.

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 end of the two electrode rods 3, which is far from the heating body 2, is exposed outside the housing 101.

The surface of the side of the oil guiding body 1 facing away from the heating body 2 is the oil guiding surface 1021, and the oil guiding 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 the power supply host, the two electrode rods 3 can be respectively connected with the positive electrode and the negative electrode of the power supply host to supply power to the heating body 2, so that the heating body 2 can heat and atomize the aerosol generating substrate 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 guiding layer 11, the middle layer 12 and the oil locking layer 13 are respectively provided with a first oil guiding hole 111, a second oil guiding hole 121 and a third oil guiding hole 131, the aperture of the first oil guiding hole 111, the aperture of the second oil guiding hole 121 and the aperture of the third oil guiding hole 131 are sequentially decreased, the first oil guiding hole 111, the second oil guiding hole 121 and the third oil guiding hole 131 are sequentially communicated, and the first oil guiding hole 111 is communicated with the outside of the oil guiding body 1.

It will be appreciated 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, which is opposite 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 for heating and atomizing the aerosol-generating substrate oozed out from the third oil guide hole 131 to form an aerosol.

The aerosol generating substrate directly contacts the oil guiding surface 1021, and flows through the first oil guiding hole 111, the second oil guiding hole 121 and the third oil guiding hole 131 to the heating body 2 in sequence under the action of gravity of the aerosol generating substrate, so that the heating body 2 can heat and atomize 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 decrease in sequence, the aerosol generating substrate is not easy to leak liquid in the process of flowing to the heating element 2, and meanwhile, the aerosol generating substrate can also fully flow into the heating element 2, the heating element is not easy to burn dry, and the aerosol generated by heating and atomizing the aerosol generating substrate has good taste.

In particular, 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 guiding surface 1021 under the action of gravity, the aerosol generating substrate diffuses and permeates into the middle layer 12 along the first oil guiding hole 111 of the oil guiding layer 11, and because the aperture of the second oil guiding hole 121 of the middle layer 12 is smaller than that of the first oil guiding hole 111 and the aperture of the second oil guiding hole 121 is larger than that of the third oil guiding hole 131 of the oil locking layer 13, the middle layer 12 plays a role in transmitting the aerosol generating substrate from the oil guiding layer 11 to the oil locking layer 13 and plays a role in storing oil and locking oil and buffering oil. When the aerosol generating substrate enters the oil locking layer 13 from the second oil guiding hole 121 of the intermediate layer 12, the capillary force of the third oil guiding hole 131 locks the aerosol generating substrate to prevent the aerosol generating substrate from flowing back or overflowing, and meanwhile, compared with the traditional method which only relies on the permeation of ceramic, the third oil guiding hole 131 on the oil locking layer 13 can enable the aerosol generating substrate to flow to the heating element 2 more quickly, so that the heating element 2 is heated and atomized to form aerosol for the user to inhale.

The oil guiding 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 middle layer 12 and the oil locking layer 13 in the embodiment shown in fig. 3 have only one layer of oil guiding holes, so that the oil guiding layer 11, the middle layer 12 and the oil locking layer 13 are all of a single-layer structure.

Referring to fig. 4, the oil guiding layer 11 of the embodiment shown in fig. 4 is a multi-layered structure. The first oil guiding hole 111 of the oil guiding layer 11 includes a first through hole 1111 and a second through hole 1112 which are communicated, 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 guiding 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 will be appreciated that in other embodiments, the number of through holes included in the oil guiding layer 11 may be three or more, the order of arranging the through holes in each layer is not limited, and the aperture of each layer of through holes is larger than that of the second oil guiding hole 121.

It will be appreciated that the intermediate layer 12 and the oil-locking layer 13 may be provided with a multi-layer through-hole structure, similar to the oil-guiding layer 11, which is advantageous for more effectively outputting and locking the aerosol-generating substrate.

Since 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 three are provided with sequentially reduced apertures according to the functions of the oil guide layer 11, the intermediate layer 12, and the oil locking layer 13. In order to better enable the oil guide body 1 to realize the oil guide and locking functions, the aperture of the oil guide holes on the oil guide layer 11, the middle layer 12 and the oil locking layer 13 can be limited to a certain extent.

In one embodiment, the first oil guide hole 111 of the oil guide layer 11 may be set to have a pore diameter of 40 microns or more and 50 microns or less; the second oil guide hole 121 of the intermediate layer 12 may be set to have a pore diameter greater than 15 micrometers (e.g., 16 micrometers) and less than 40 micrometers (e.g., 39 micrometers); the third oil guide hole 131 of the oil locking layer 13 may be set to have a pore diameter of 5 micrometers or more and 15 micrometers or less.

The extending direction of the fourth sub oil hole 113, the extending direction of the first sub oil hole 112 and the extending direction of the first oil guide hole 111 are perpendicular to each other, and it is understood that the extending direction of the fourth sub oil hole 113, the extending direction of the first sub oil hole 112 and the extending direction of the first oil guide hole 111 are arranged along the directions in which the X-axis, the Y-axis and the Z-axis extend in the coordinate system of fig. 5, respectively. 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 guiding hole 111 may be disposed at other angles, such as 45 ° or 60 °, and the like, which is not limited herein.

Neither the first auxiliary oil hole 112 nor the fourth auxiliary oil hole 113 penetrates the oil guiding layer 11 to avoid leakage of the aerosol generating substrate from the side of the oil guiding layer 11. Note that, in the embodiment shown in fig. 5, a portion is cut at both right-angle sides of the oil guiding layer 11, so that the first auxiliary oil hole 112 and the fourth auxiliary oil hole 113 are shown for clarity.

When the heat generating member 23 generates heat, the aerosol generating substrate can be heated and atomized into aerosol by the high temperature generated around the heat generating member 23.

The heat generating element 23 of the embodiment shown in fig. 6 is of an "S" shape, and such a shape of the heat generating element 23 is advantageous in increasing the heat generating area and improving the atomization efficiency.
