[0032] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] The following combination Figures 1 to 5 , describing the embodiments of the present utility model.

[0035] Please refer to Figure 1 and Figure 5 As shown, the atomization structure 100 of the present application includes an oil cup 1 and a heating element 2, a silicone element 3 and an isolating element 4 arranged in the oil cup 1. The oil cup 1 is used to store the atomized liquid. The heating element 2 has liquid-conducting micropores (not shown in the figure). The heating element 2 is arranged in the silicone element 3. The isolating element 4 is arranged between the silicone element 3 and the heating element 2. The isolating element 4 is used to separate the silicone element 3 and the heating element 2.

[0036] In this embodiment, the heating element 2 has liquid-conducting micropores, and the heating element 2 is arranged in the oil cup 1. The heating element 2 can absorb the atomized liquid in the oil cup 1 through the liquid-conducting micropores and heat the absorbed atomized liquid into an aerosol; in addition, an isolation member 4 is provided between the silicone member 3 and the heating element 2. The isolation member 4 is used to separate the silicone member 3 and the heating element 2. The isolation member 4 can isolate or reduce the contact between the silicone member 3 and the heating element 2 to prevent or reduce the silicone oil precipitated from the silicone member 3 from penetrating into the liquid-conducting micropores of the heating element 2 and clogging the liquid-conducting micropores, thereby reducing the problem of the core of the heating element 2 being sticky due to poor oil conduction.

[0037] In one embodiment, Figure 2 and Figure 5 As shown, the heating element 2 includes an atomizing portion 22, the liquid guide micropores are provided on the atomizing portion 22, the isolating member 4 is sleeved on the peripheral side wall of the atomizing portion 22, and the isolating member 4 is an isolating cotton. In this embodiment, the material of the atomizing portion 22 is not limited, and the atomizing portion 22 can be a porous ceramic core or a cotton core. Preferably, the atomizing portion 22 is a porous ceramic core. The fixing method between the isolating member 4 and the atomizing portion 22 is also not limited. The isolating member 4 can be fixed to the peripheral side wall of the atomizing portion 22 by crimping, snap connection or other methods.

[0038] Furthermore, the spacer 4 is made of insulating cotton. The material of the insulating cotton is not limited and can be any one of PET, polyester fiber, high-density cotton, etc. The spacer 4 is made of insulating cotton. As a porous material, the fiber structure of the insulating cotton can, to a certain extent, block or reduce the penetration of the silicone oil precipitated from the silicone member 3 into the liquid guide micropores, thereby reducing the problem of dry burning of the heating element 2 due to poor oil conduction.

[0039] In one embodiment, Figure 4 and Figure 5 As shown, the silicone member 3 has a mounting groove 31, and the isolating member 4 and the atomizing portion 22 are fixed in the mounting groove 31. The groove wall of the mounting groove 31 and the atomizing portion 22 respectively squeeze the isolating member 4 to clamp the isolating member 4 between the silicone member 3 and the heating element 2.

[0040] In this embodiment, the groove wall of the mounting groove 31 and the atomizing part 22 respectively squeeze the isolating part 4 to clamp the isolating part 4 between the silicone part 3 and the heating part 2. The isolating part 4 can be fixed between the silicone part 3 and the heating part 2 without the assistance of other clips and other components. The installation and fixation of the isolating part 4 is simple and convenient. In addition, the groove wall of the mounting groove 31 and the atomizing part 22 are respectively squeezed and contacted with the isolating part 4. The isolating part 4 can fill the gap between the groove wall of the mounting groove 31 and the outer peripheral side wall of the atomizing part 22. The atomized liquid entering the gap can be absorbed by the isolating part 4 to prevent the atomized liquid from leaking out of the gap between the groove wall of the mounting groove 31 and the outer peripheral side wall of the atomizing part 22.

[0041] In one embodiment, Figure 4 and Figure 5 As shown, the mounting groove 31 further includes a first opening 32, and the atomizing unit 22 includes a liquid suction surface 221, which communicates with the oil cup 1 through the first opening 32. In this embodiment, the liquid suction surface 221 is exposed to the oil cup 1 through the first opening 32. The atomized liquid in the oil cup 1 can contact the liquid suction surface 221 of the atomizing unit 22 through the first opening 32, facilitating the liquid-guiding micropores on the liquid suction surface 221 to absorb the atomized liquid in the oil cup 1.

[0042] In one embodiment, Figures 1 to 3 As shown, the atomization structure 100 further includes a mounting base 5, which is fixed to the oil cup 1 and defines a mounting cavity 51. The silicone member 3, the heating element 2, and the isolation member 4 are fixed to the mounting cavity 51. The outer wall of the silicone member 3 is in sealed contact with the inner wall of the mounting cavity 51. In this embodiment, the outer wall of the silicone member 3 is in sealed contact with the inner wall of the mounting cavity 51, thereby preventing the atomized liquid in the oil cup 1 from leaking through the gap between the outer wall of the silicone member 3 and the inner wall of the mounting cavity 51.

[0043] In one embodiment, Figures 1 to 3 As shown, the mounting seat 5 also includes a guide groove 52, which is connected to the mounting cavity 51. The guide groove 52 and the mounting cavity 51 are arranged in sequence along the gravity direction of the mounting seat 5.

The guide slope 53 is arranged around the edge of the first opening 32, and a recessed portion 222 is provided on the liquid suction surface 221.

[0044] In this embodiment, when the atomization structure 100 is in use, the guide groove 52 is located above the installation cavity 51, and the guide slope 53 is located at the bottom of the guide groove 52. The guide slope 53 has a drainage function, which can guide the atomized liquid in the guide groove 52 to the first opening 32. After passing through the first opening 32, the atomized liquid flows into the liquid suction surface 221 and the recessed portion 222. Especially when the amount of atomized liquid is too low, less atomized liquid can remain in the recessed portion 222, thereby improving the utilization rate of the atomized liquid.

[0045] In one embodiment, Figures 1 to 3 As shown, a sealing ring 54 is also provided around the outer periphery of the mounting seat 5. The sealing ring 54 is positioned between the outer wall of the mounting seat 5 and the inner wall of the oil cup 1 to seal the gap between the mounting seat 5 and the oil cup 1.

The sealing ring 54 is in sealing contact with the outer wall of the mounting seat 5 and the inner wall of the oil cup 1, respectively, to prevent the atomized liquid in the oil cup 1 from leaking through the gap between the outer wall of the mounting seat 5 and the inner wall of the oil cup 1.

[0046] In one embodiment, Figure 1 and Figure 5 As shown, the atomization structure 100 also includes a first fixing seat 6, on which an electrode 61 is provided; the mounting groove 31 also includes a second opening 33, which is arranged opposite to the first opening 32, and the heating element 2 also includes a heating portion 21, which is located on the side of the atomization portion 22 close to the second opening 33. After passing through the second opening 33, the electrode 61 abuts against the heating portion 21, and the electrode 61 can provide support for the heating portion 21.

[0047] In this embodiment, the specific shape of the heating portion 21 is not limited. The heating portion 21 can be a heating wire, a heating sheet, a heating net, or a heating structure of other shapes. The heating portion 21 is used to heat the atomizing portion 22, so that the atomized liquid in the atomizing portion 22 is converted into an aerosol after being heated.

The mounting seat 5, the first fixing seat 6, the circuit board 7 and the second fixing seat 8 are arranged in sequence along the central axis direction of the oil cup 1; the atomization structure 100 also includes a suction nozzle 9 and a first air guide channel 10 that are connected to each other. The suction nozzle 9 is arranged on the side of the oil cup 1 away from the mounting seat 5. The first air guide channel 10 is arranged side by side with the oil cup 1.

[0049] Specifically, the aerosol generated by the heating element 2 enters the third air guide channel 62 through the second opening 33. At the same time, the external air enters the third air guide channel 62 through the fourth air guide channel 81 and the air hole 71 and mixes with the aerosol. The aerosol then passes through the second air guide channel 56 and the first air guide channel 10 in sequence and enters the mouthpiece 9, and then enters the human mouth from the mouthpiece 9.

[0050] According to an embodiment of the present invention, an aerosol generating device is further provided, comprising the atomizing structure 100 as described above.
