Meanwhile, the steps or actions in the method description can also be sequentially exchanged or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0031] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0032] As shown in FIGS. 1-3, 8, the electronic cigarette oil bottle sealing structure includes sealing silica gel 1, cup cover 2, push cover 3, oil storage cup 4, sealing rubber ring 5 and push cover sealing silica gel 6; the cup cover 2 is provided on the cup opening of the oil storage cup 4, and is connected with the top end of the oil storage cup 4 in a buckle type. The top of the cup cover 2 is densely provided with sealing silica gel 1; the top surface of the sealing silica gel 1 is film-shaped and forms a petal-shaped cutout.

[0033] The upper end of the push cover 3 forms a columnar shape matched with the inner side of the cup cover 2, and the bottom end of the push cover 3 forms a generally square shape matched with the inner side of the oil storage cup 4. It can be understood that in other embodiments, the upper end of the push cover 3 and the inner side of the cup cover 2 can also be generally square, such as a square or rectangular shape, and the bottom end of the push cover 3 and the inner side of the oil storage cup 4 can also be columnar, such as a cylindrical shape, which is not limited. The upper end of the push cover 3 is provided with a sealing rubber ring 5 between the upper end of the push cover 3 and the inner side of the cup cover 2; the bottom end of the push cover 3 is provided with a push cover sealing silica gel 6 between the bottom end of the push cover 3 and the inner side of the oil storage cup 4. The upper end of the push cover 3 can slide in the cup cover 2, and the square-shaped bottom end can slide in the oil storage cup 4.

[0034] The sealing silica gel 1 has a petal-shaped cutout. When the electronic cigarette oil bottle structure is not installed in the electronic cigarette, the cutout is closed to prevent the leakage of the tobacco tar in the oil storage cup 4, and when the electronic cigarette oil bottle structure is installed in the electronic cigarette, the cutout is opened by the oil guide column 8 to guide the tobacco tar in the oil storage cup 4 to the liquid storage cotton 7.

[0035] The inner diameter of the opening top end of the oil storage cup 4 is expanded to form a step 41; the step 41 limits the stroke of the push cover 3 sliding into the oil storage cup 4.

[0036] The push cover 3 is provided with an oil passage hole passing through the top end of the oil storage cup 4 and the cup cover 2.

[0037] When the oil bottle is assembled with the rest of the electronic cigarette, a relative position as shown in Figs. 4 and 5 can be formed. Then, the oil bottle is pushed upwards; the structure and position after the pushing are shown in Figs. 6 and 7. During the assembly of the oil bottle and after the assembly is completed; the oil guide column 8 pierces the sealing silica gel 1 and pushes the push cap 3 to slide into the oil storage cup 4 to the bottom end of the stroke; at this time, the push cap sealing silica gel 6 is against the step 41. The tobacco oil in the oil storage cup 4 flows into the oil storage cotton 7 along the oil guide column 8 under the action of pressure. Thus, the oiling of the oil storage cotton 7 is realized.

[0038] As shown in Fig. 7, the electronic cigarette further comprises a mouthpiece 9, and the oil bottle is arranged away from the mouthpiece 9 relative to the oil storage cotton 7. When the oil bottle is assembled into the electronic cigarette, the oil guide column 8 can pierce the cut of the sealing silica gel 1 and move the push cap 3 within the stroke of the step 41 of the oil storage cup 4. At this time, since the oil storage cup 4 is full of tobacco oil, the tobacco oil flows from the oil storage cup 4 through the oil hole of the push cap 3 and out of the cut of the sealing silica gel 1 to the oil storage cotton 7 under the pressure of the push cap 3. In this way, when the oil bottle is installed into the electronic cigarette, the tobacco oil can quickly enter the oil storage cotton 7, and it is not necessary to realize the replenishment of the tobacco oil by turning over, especially when the oil storage cotton 7 is not pre-oiled with tobacco oil, the rapid wetting of the atomization assembly can be realized, the waiting time for the user to assemble the oil bottle structure into the electronic cigarette is shortened, the amount of tobacco oil injection can be stably controlled, and the user experience is improved.

[0039] As shown in Fig. 7, the oil guide column 8 is inserted into the oil storage cotton 7 from one end of the oil storage cotton 7 away from the oil bottle and extends out of the oil storage cotton 7 from the other end and is inserted into the oil bottle. The tobacco oil in the oil bottle can flow out of the cut of the sealing silica gel 1 along the oil guide column 8 and flow to the oil storage cotton 7 along the oil guide column 8. Meanwhile, the electronic cigarette further comprises an atomization assembly, and the oil storage cotton 7 defines an atomization space, and the atomization assembly is arranged in the atomization space and is used for atomizing the tobacco oil on the oil storage cotton 7. In this application, the atomization assembly and the oil guide column 8 are arranged side by side on the oil storage cotton 7, when the oil guide column 8 guides the tobacco oil to the oil storage cotton 7, the oil storage cotton 7 guides the tobacco oil to the atomization assembly, and the atomization assembly can atomize the tobacco oil.

[0040] In addition, there is a gap between the outer side wall of the oil guide column 8 inserted into the oil storage cotton 7 and the oil storage cotton 7, which can facilitate the rapid entry of the tobacco oil into the oil storage cotton 7.

[0041] As shown in Figs. 5 and 7, the oil bottle can be detachably installed on the electronic cigarette, and the specific installation manner is not limited as long as it can be conveniently detached and installed. Based on this, the oil bottle of the present application can be replaced, and the other electronic elements of the electronic cigarette can be repeatedly used, which can save resources and reduce the use cost. In addition, when the user does not use it for a long time, the oil bottle can be detached from the electronic cigarette. Since the cut of the sealing silica gel 1 can be automatically closed, even if the oil bottle is detached, there will be no problem of oil leakage.
