As shown in fig. 2B, in some embodiments, the top plug 12 includes a body 12B, and the air outlet 12a extends through the body 12B. The top plug 12 has a third opening 12e and a fourth opening 12f opposite to each other. The third opening 12e and the fourth opening 12f communicate with the air outlet passage 12 a. The top plug 12 includes a projection 12h at its juncture with the mouthpiece cover 30 that extends in the direction of the mouthpiece cover. In some embodiments, the mouthpiece cover direction is equal to the longitudinal axis direction L. In some embodiments, the air outlet channel 12a penetrates through the protrusion 12h, and the third opening 12e is formed on the protrusion 12 h. The hollow convex column 30b of the mouthpiece cover 30 can be inserted into the convex portion 12h, so that the air outlet passage 12a is communicated with the outlet passage 30 a. In some embodiments, the protrusion 12h of the top plug 12 may be inserted into the hollow boss 30b of the mouthpiece cover 30. In some embodiments, the wall surface of the air outlet channel 12a in the protruding portion 12h may have a concave-convex structure. The concave-convex structure can strengthen the fixation of the hollow convex column 30b of the cigarette holder cover 30 and prevent the tobacco tar from overflowing from the joint of the top rubber plug 12 and the cigarette holder cover 30.
As shown in fig. 2B, 3A and 3B, in some embodiments, the top rubber plug 12 includes a fixing structure 12c disposed around the side of the body 12B. The securing structure 12c is adapted to engage a corresponding structure within the mouthpiece cover 30. In some embodiments, the top plug 12 includes a groove 12i circumferentially disposed at the bottom of the body 12 b. The oil cup includes a convex wall 11f located around the first opening 11 b. The convex wall 11f extends toward the top plug 12. The groove 12i and the protruding wall 11f can be fixed to each other, so that the strong top rubber plug 12 is fixed on the oil cup 11. In some embodiments, the junction of the top plug 12 and the cannula 14 (i.e., the top opening 14b) extends in the direction of the cannula to form a protrusion 12g, which may further strengthen the junction structure and prevent the oil from leaking from the junction of the top plug 12 and the cannula 14. As shown in fig. 2B, in some embodiments, the air outlet channel 12a of the top rubber plug 12 sequentially penetrates through the protrusion 12g, the body 12B and the protrusion 12 h. In this embodiment, the extension direction of the cannula 14 is identical to the longitudinal axis direction L.
In some embodiments, the top plug 12 includes an oil injection channel 12d extending through the body 12 b. The oil filling channel 12d is located around the air outlet channel 12 a. In the present embodiment, the number of the oil filling passages 12d is two, but the number of the oil filling passages 12d is not intended to limit the present invention.
FIG. 4 is a partially exploded cross-sectional view of an atomizing device according to some embodiments of the present application. As shown in fig. 4, after the top rubber plug 12 is fixed to the oil cup 11, the user can inject the tobacco tar from the oil filling channel 12d into the storage bin 11a in the oil cup 11. Meanwhile, the oil storage structure 56 may adsorb the injected soot. After the step of injecting the tobacco tar into the storage bin 11a is completed, the user can mount the mouthpiece cover 30 on the top rubber plug 12 to complete the mounting of the atomizing device 100, as shown in fig. 1E. In some embodiments, because the top open-ended input of the air-outlet channel 12a is higher than the top open-ended input of the oil-inlet channel 12d, the open-ended input of the air-outlet channel 12a is higher than the top open-ended input of the oil-inlet channel 12 d. We have inside the user, by injecting fuel into oiling channel 12d, since raised portion 12h oiling channel 12d and exhausting channel 12a are separate, and because of the fact that the top end of the exhausting channel 12a is open-ended, bright-sight-improving on the top end of the oiling channel 12d, avoiding the user accidentally injecting fuel into the exhausting channel 12 a.
the provision of the oil injection channel 12d in the top plug 12 has a number of advantages. During the assembly of the atomizing device 100, all the components except the mouthpiece cover 30 can be assembled into a semi-finished product in advance, and the oil is not injected into the oil cup 11 for the time being. The top plug 12 secured over the oil cup 11 seals the oil reservoir structure 56 within the storage bin 11 a. The assembled semi-finished product can be transported to all over the world together with the mouthpiece cover 30, and then the tobacco tar is injected into the oil cup 11 through the oil injection channel 12d of the top rubber plug 12 after the transportation is completed.
The tobacco tar can be injected after the transportation is finished, so that the tobacco tar in the storage bin 11a can be prevented from deteriorating in the transportation process. The tobacco tar is injected after the transportation is finished, so that the tobacco tar can be prevented from leaking from the storage bin 11a due to pressure marginalization in the transportation process.
in some embodiments, the storage bin 11a may be defined by the inner walls of the oil cup 11, the top plug 12, the heater 13, the cannula 14, and the oil cup base 15. In some embodiments, the storage 11a may store the tobacco tar directly.
In some embodiments, the storage compartment 11a may further comprise an oil storage structure 56 disposed in the storage compartment 11 a. The oil storage structure 56 is used for storing tobacco tar. In some embodiments, the oil retaining structure 56 is integrally formed, i.e., the oil retaining structure 56 is block-shaped. Examples of the oil storage structure 56 include, but are not limited to, an oil storage bag, an oil storage box, or a porous oil storage material, such as a polymer material, oil storage cotton, ceramic, or silicone.

In some embodiments, the cross-sectional shape of the reservoir structure 56 may be an eye, as shown in fig. 3A and 3B. In some embodiments, the oil reservoir structure 56 is made of a flexible material. As shown in fig. 1E and 2B, in some embodiments, since the oil reservoir structure 56 is an elastomer, the oil reservoir structure 56 will closely fit adjacent components when compressed during assembly. In some embodiments, the oil storage structure 56 substantially occupies almost the entire storage compartment 11 a.
As shown in fig. 1E, the oil cup base 15 includes a first air inlet passage 15a and an electrical connection passage 15 b.

In some embodiments, the diameter of the top end of the first air inlet passage 15a near the insertion tube 14 is smaller than the diameter of the bottom end of the first air inlet passage 15a near the battery assembly 100B to reduce the leakage of soot through the first air inlet passage 15 a. In some embodiments, the first air intake passage 15a further comprises a filter (not shown) that is capable of allowing airflow therethrough and preventing unaeromized or condensed soot from passing therethrough, further reducing spillage of soot through the air intake passage. In some embodiments, the filter comprises a porous material, for example, an oil absorbent cotton, porous carbon.
As shown in fig. 3A and 3B, the joint of the oil cup base 15 and the insertion tube 14 (i.e., the bottom end opening 14c) extends toward the insertion tube to form a convex portion 15 d. The boss 15d extends from the body 15c toward the cannula 14. The first air intake passage 15a penetrates the body 15c and the boss 15 d.

The oil absorption layer 23 may absorb the condensed liquid in the first air intake passage 15 a. The oil absorption layer 23 can prevent the condensed liquid in the first air intake passage 15a from leaking to the battery assembly 100B. The oil absorption layer 23 can also absorb the smoke oil leaked from the electric connecting channel 15 b.
In addition, in some embodiments, the bottom openings of the first air inlet passage 15a and the electrical connection passage 15b are formed on the groove 15 f. As shown in fig. 3B, in some embodiments, battery support 16 may include a screen 16a extending toward oil storage assembly 100A with respect to an object.
