[0035] like Figures 1 to 6 As shown, an embodiment of the utility model provides an electronic cigarette 100, including an oil storage tank assembly 110 and an atomizer assembly 120. The oil storage tank assembly 110 includes a box body 111 and oil storage cotton 112. The box body 111 includes a first cavity 111a, a second cavity 111b and at least one oil control hole 111c. The first cavity 111a is connected to the second cavity 111b through at least one oil control hole 111c. The oil storage cotton 112 is arranged in the first cavity 111a. When the electronic cigarette 100 is in normal use, the second cavity 111b is located above the first cavity 111a; the atomizer assembly 120 is arranged in the first cavity 111a.

[0036] In the above embodiment, the first cavity 111a is used to store the e-liquid, the atomizer assembly 120 is arranged in the first cavity 111a to atomize the e-liquid in the oil storage cotton 112, the second cavity 111b is arranged above the first cavity 111a, and the second cavity 111b is used to replenish the e-liquid in the first cavity 111a. When the e-liquid in the first cavity 111a is used up, the e-liquid in the second cavity 111b can flow into the oil storage cotton 112 in the first cavity 111a through the oil control hole 111c under the action of gravity. Compared with the electronic cigarette 100 with only one cavity, the second cavity 111b is added to control the flow rate of the e-liquid, and it is not easy to have the risk of leakage caused by too much e-liquid in the first cavity 111a or overheating damage of the atomizer assembly 120 due to too little e-liquid. A partition is arranged in the middle of the box 111, and the partition separates the box 111 into the first cavity 111a and the second cavity 111b. During use, since the second cavity 111b is arranged above the first cavity 111a, the tobacco oil in the second cavity 111b slowly flows into the first cavity 111a from top to bottom through the oil control hole 111c due to the action of gravity, which can more evenly soak the oil storage cotton 112, improve the atomization effect, and prevent malfunctions such as oil leakage or core sticking.

[0037] In some embodiments, Figure 2 , Figure 3 As shown, the electronic cigarette 100 also includes an oil replenishing bottle 140, and the housing 111 also includes an oil inlet hole 111f. The oil replenishing bottle 140 is connected to the second cavity 111b through the oil inlet hole 111f. The oil replenishing bottle 140 is used to replenish oil into the second cavity 111b. The smoke oil first flows into the second cavity 111b through the oil inlet hole 111f, and then flows into the first cavity 111a through the oil control hole 111c between the first cavity 111a and the second cavity 111b, thereby slowing down the flow rate of the smoke oil. Compared with the oil replenishing bottle 140 directly connected to the first cavity 111a, it is safer and more stable. In this embodiment, the oil replenishing bottle 140 is connected to the housing 111 on the left and right, and in some other embodiments, it can also be connected to the housing 111 up and down. After the oil storage cotton 112 absorbs the smoke oil, the electronic cigarette 100 can continue to be used, thereby extending the battery life of the electronic cigarette 100 and increasing the service life of the atomization assembly 120. One side of the oil replenishing bottle 140 is a plane and the other side is a curved surface. The plane side is connected to the box body 111, and the curved side is smooth without edges and corners, which is convenient for users to hold. Anti-slip patterns or silicone packaging can be set on the outer surface of the oil replenishing bottle 140 to further improve the user's grip experience and prevent slipping during use.

[0038] In some embodiments, Figure 4 , Figure 5As shown, the oil inlet 111f is located on the top side wall of the box body 111. The oil replenishing bottle 140 is connected to the box body 111 left and right, the first cavity 111a and the second cavity 111b are connected up and down, and the oil inlet 111f and the oil control hole 111c are not in the same direction, so as to better control the flow rate of the oil. When the oil is used up, the user places the electronic cigarette 100 horizontally, and the oil can flow from the oil replenishing bottle 140 into the second cavity 111b. Then the electronic cigarette 100 is placed vertically, and the oil flows from the second cavity 111b into the first cavity 111a. The upper and lower ends of the box body 111 are provided with sealing cover plates. After the internal parts of the oil storage tank assembly 110 are installed, the box body 111 is sealed with a cover plate to prevent the oil in the first cavity 111a and the second cavity 111b from leaking out.

[0039] In some embodiments, the oil replenishing bottle 140 includes an oil bottle interface 141, and the oil bottle interface 141 is arranged corresponding to the oil inlet hole 111f. The smoke oil flows out of the oil replenishing bottle 140 through the oil bottle interface 141, and then flows into the oil inlet hole 111f of the second cavity 111b. The shape of the oil bottle interface 141 is adapted to the shape of the oil inlet hole 111f. The oil bottle interface 141 is arranged at the upper end of the side of the oil replenishing bottle 140. In this embodiment, the oil bottle interface 141 is a flat mouth, and in other embodiments, the oil bottle interface 141 can be any shape.

[0040] In some embodiments, the oil replenishing bottle 140 further includes a sealing member 142, which is coated on the oil bottle interface 141. When the oil bottle interface 141 and the oil inlet hole 111f are connected, the oil bottle interface 141 and the oil inlet hole 111f are sealed by the sealing member 142 to prevent the oil from leaking out. In this embodiment, the sealing member 142 is made of a silicone packaging material, which is coated on the inner and outer sides of the oil bottle interface 141. When the oil bottle interface 141 and the oil inlet hole 111f are installed accordingly, the sealing member 142 is sandwiched between the oil bottle interface 141 and the oil inlet hole 111f, thereby ensuring the sealing between the oil replenishing bottle 140 and the second cavity 111b.

[0041] In the above embodiment, the sealing member 142 may also be a sealing cover with a petal-shaped seal, which is arranged on the oil bottle interface 141. The diameter of the oil bottle interface 141 is slightly larger than the oil inlet hole 111f. The oil inlet hole 111f is provided with an insertion portion. When the box body 111 and the oil replenishing bottle 140 are docked, the insertion portion is inserted into the seal of the sealing member 142 to open the sealing member 142. The sealing member 142 is clamped between the outer side of the insertion portion and the inner side of the oil bottle interface 141.

[0042] In the above embodiment, the sealing member 142 may also be made of flexible materials such as rubber or polyethylene compounds.

[0043] In some embodiments, the electronic cigarette 100 further includes a housing 130 and a mouthpiece assembly 150. One end of the housing 130 has an opening 131. The oil tank assembly 110 is located in the housing 130. The oil refill bottle 140 is detachably connected to the housing 130. The mouthpiece assembly 150 is disposed at the opening 131, and the mouthpiece assembly 150 is connected to the atomizer assembly 120. When assembling the electronic cigarette 100, first install the oil tank assembly 110, the atomizer assembly 120 and other parts into the housing 130 from the opening 131, and then install the mouthpiece assembly 150 at the opening 131 of the housing 130. In this embodiment, the mouthpiece assembly 150 is sealedly connected to the opening 131, and a non-sealed connection may also be used. The oil refill bottle 140 is detachable, which facilitates the replenishment of oil in the oil refill bottle 140 after the oil is exhausted or replaces the oil refill bottle 140 with a new one. During transportation, the oil replenishing bottle 140 can be transported separately from the housing 130. Before use, the user assembles the oil replenishing bottle 140 and the housing 130 together to prevent excessive oil in the oil replenishing bottle 140 from flowing into the second cavity 111b and the first cavity 111a, thereby causing oil leakage or excessive oil absorption by the oil storage cotton 112, resulting in a burnt smell during use. The side of the housing 130 is provided with a small hole, which corresponds to the position of the oil inlet hole 111f of the box 111 and the oil bottle interface 141 of the oil replenishing bottle 140. The oil replenishing bottle 140 is connected to the housing 130 on the left and right. In this embodiment, the oil replenishing bottle 140 is connected to the housing 130 in a snap-fit ​​manner. The upper and lower ends of the oil replenishing bottle 140 are provided with snap-fitting parts, and the housing 130 is provided with grooves at the position corresponding to the snap-fitting parts, and the snap-fitting parts and the grooves can be snap-fitted correspondingly. In some other embodiments, it is not limited to other connection methods such as magnetic attraction, bonding, or riveting.

[0044] In some embodiments, the housing 111 further includes a smoke outlet pipe 111d, which is disposed through the second cavity 111b. A smoke outlet hole 111e is disposed between the first cavity 111a and the second cavity 111b. The smoke outlet pipe 111d is sealedly connected to the smoke outlet hole 111e, and the mouthpiece assembly 150 is connected to the atomizer assembly 120 through the smoke outlet pipe 111d. The aerosol generated after the atomizer assembly 120 atomizes the smoke oil is sucked out through the smoke outlet hole 111e and inhaled by the user through the smoke outlet pipe 111d and the mouthpiece assembly 150. The smoke outlet pipe 111d isolates the second cavity 111b from the volatilization channel of the aerosol, preventing the smoke oil from being sucked out or the condensate of the mouthpiece assembly 150 from penetrating.

[0045] In some embodiments, the number of oil control holes 111c is multiple, and the multiple oil control holes 111c are evenly arranged around the outer periphery of the smoke outlet hole 111e. Multiple evenly distributed oil control holes 111c are conducive to the uniform flow of smoke oil into the first cavity 111a. Four evenly distributed oil control holes 111c are arranged on the outside of the smoke outlet hole 111e of this embodiment, and the smoke oil flows evenly into the oil storage cotton 112 around the atomization assembly 120. In some other embodiments, it is not limited to setting four, and it can be three, five or more. As long as the first cavity 111a and the second cavity 111b are provided with connected oil control holes 111c, they all fall within the protection scope of the utility model. The size of the oil control hole 111c can be set according to actual conditions. The oil control hole 111c of the electronic cigarette 100 with fast smoke oil consumption can have a larger diameter and increase the number of oil control holes 111c. The electronic cigarette 100 with slow smoke oil consumption can be set with a small diameter and fewer oil control holes 111c.

[0046] In some embodiments, the electronic cigarette 100 further includes a circuit board 160 and a battery 170. The circuit board 160 is located in the housing 130 and is electrically connected to the atomizer assembly 120.
