[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Refer to the attached Figure 5-8 , an electronic cigarette oil bottle in an embodiment of the present utility model.

[0044] The electronic cigarette oil bottle 1 is used to be assembled on the cigarette cartridge structure, and is used to add cigarette oil to the atomizing core 2 when assembled on the cigarette cartridge structure.

[0045] The electronic cigarette oil bottle 1 includes a bottle body 11, a first sealing member 12 and a bracket 13. A first oil chamber 16 with a first opening 110 on one side is provided in the bottle body 11, and the first oil chamber 16 is used to store the e-liquid. The first sealing member 12 is at least partially arranged at the first opening 110, and the side wall of the first sealing member 12 is interference fit with the bottle body 11. The first sealing member 12 is provided with a first oil outlet 121 connected to the first oil chamber 16. The bracket 13 is arranged in the bottle body 11, and the bracket 13 is provided with a second oil outlet 131 connected to the first oil outlet 121. A sealing plug 14 is movably provided on the first sealing member 12. When the oil bottle 1 is not assembled to the cigarette cartridge structure, the sealing plug 14 is placed in the first oil outlet 121 and / or the second oil outlet 131 to seal the first oil outlet 121 and / or the second oil outlet 131. When the oil bottle 1 is assembled on the cigarette cartridge structure, the sealing rubber plug 14 is pushed away from the first oil outlet 121 and the second oil outlet 131 by the pushing member 31 of the cigarette cartridge structure.

[0046] The oil bottle 1 of this embodiment is configured with a first sealing member 12 and a bracket 13 to seal the first opening 110 of the bottle body 11. A first oil outlet hole 121 and a second oil outlet hole 131 are respectively formed in the first sealing member 12 and the bracket 13. A sealing plug 14 is movably disposed within the first oil outlet hole 121 and / or the second oil outlet hole 131. Thus, when the sealing plug 14 is placed on the first oil outlet hole 121 and / or the second oil outlet hole 131, the first oil chamber 16 is sealed. Furthermore, when the oil bottle 1 is assembled onto a cigarette cartridge structure, the sealing plug 14 is pushed away from the first oil outlet hole 121 and the second oil outlet hole 131 by the pusher 31 of the cigarette cartridge structure, thereby opening the first oil outlet hole 121 and the second oil outlet hole 131. This allows the oil in the first oil chamber 16 to flow out through the first oil outlet hole 121 and the second oil outlet hole 131 in sequence, thereby replenishing the cigarette cartridge structure with oil. Furthermore, the oil bottle 1 has a simple structure, which can effectively reduce the production cost of the oil bottle 1 , facilitate production, and reduce production time.

[0047] In the above embodiment, the sealing rubber plug 14 is provided with a pulling portion 141. The outer contour of the pulling portion 141's cross section is smaller than the outer contour of the first oil outlet hole 121 and smaller than the outer contour of the second oil outlet hole 131. This allows the pulling portion 141 to pass through the first oil outlet hole 121 and the second oil outlet hole 131 in sequence from within the first oil chamber 16 and then be positioned outside the first oil chamber 16. In this way, the first sealing rubber member 12 and the bracket 13 can be installed on the bottle body 11, with the sealing rubber plug 14 positioned within the first oil chamber 16 and the pulling portion 141 partially positioned outside the first oil bottle 1. Cigarette oil can be injected into the first oil chamber 16 from the second oil outlet hole 131 or the first oil outlet hole 121. The pulling portion 141 can then be pulled to position the sealing rubber plug 14 within the first oil outlet hole 121 or the second oil outlet hole 131, thereby sealing the first oil chamber 16 and preventing cigarette oil leakage. Of course, it is also possible to directly inject the e-liquid into the first oil chamber 16 before the first sealing member 12 and the bracket 13 are assembled on the bottle body 11, and then install the first sealing member 12 and the bracket 13. During this process, excess air will be discharged from the first oil outlet 121 and the second oil outlet 131, and then the sealing plug 14 can be placed in the first oil outlet 121 or the second oil outlet 131 by pulling the pulling portion 141 to seal the first oil chamber 16, thereby also realizing the injection of e-liquid into the oil bottle 1.

[0048] In one embodiment, the pull portion 141 is provided with a breaking notch 142 near the sealing plug 14. When the sealing plug 14 is placed within the first oil outlet 121 and / or the second oil outlet 131, the pull portion 141 is severed at the breaking notch 142. The provision of the breaking notch 142 allows the pull portion 141 to be pre-separated when the oil bottle 1 is assembled into the cartridge structure, preventing excess pull portion 141 from interfering with the assembly of the oil bottle 1 into the cartridge structure.

[0049] In one embodiment, to simplify the manufacturing process of the oil bottle 1, the sealing plug 14 is integrally injection-molded with the first sealing member 12. The width of the first oil outlet 121 is greater than the width of the second oil outlet 131. The sealing plug 14 is positioned within the first oil outlet 121. The cross-sectional profile of the sealing plug 14 is smaller than that of the first oil outlet 121, and the sidewalls of the sealing plug 14 form an interference fit with the sidewalls of the second oil outlet 131. This creates a gap between the sealing plug 14 and the sidewalls of the first oil outlet 121, allowing for air circulation and facilitating installation of the first sealing member 12 within the bottle body 11.

[0050] In one embodiment, a first stopper plate 143 is provided at or near the top of the sealing plug 14. The outer contour of the cross section of the first stopper plate 143 is smaller than the outer contour of the cross section of the first oil outlet hole 121, and is larger than the outer contour of the cross section of the second oil outlet hole 131. The first stopper plate 143 abuts against the top surface of the bracket 13 to prevent the sealing plug 14 from moving out of the second oil outlet hole 131 when the user pulls the sealing plug 14 with the pull portion 141.

[0051] In one embodiment, the outer wall of the sealing plug 14 is provided with a chamfer 144 at one end away from the first oil chamber 16 . The chamfer 144 serves as a guide to facilitate the sealing plug 14 to be placed in the second oil outlet 131 under the pulling force of the pulling portion 141 .

[0052] In one embodiment, a plurality of first clamping blocks 133 are provided on the outer wall of the bracket 13, and a first clamping groove 117 for adapting to the first clamping block 133 is opened on the inner wall of the bottle body 11. The first clamping block 133 is placed in the first clamping groove 117 to fix the bracket 13, and the first sealing member 12 is located above the first clamping block 133.

[0053] In one embodiment, the bottle body 11 has a sleeve hole 15 in the middle, and the first oil chamber 16 is annular. The bottle body 11 includes a first annular wall 115, a second annular wall 116 located within the first annular wall 115, and first panels 114 on both sides connected to the first annular wall 115 and the second annular wall 116.

[0054] The bracket 13 is annular, and the first sealing member 12 includes a first rubber ring 123, an annular panel 124, and a second rubber ring 125 located within the first rubber ring 123. The first rubber ring 123 and the second rubber ring 125 are respectively connected to either side of the annular panel 124. The first rubber ring 123 is located between the first annular wall 115 and the bracket 13, and the second rubber ring 125 is located between the second annular wall 116 and the bracket 13. The bracket 13 is at least partially located between the first annular wall 115 and the second annular wall 116, thereby securing the bracket 13 within the bottle body 11 via the first sealing member 12. The annular panel 124 is located above the bracket 13 and between the first annular wall 115 and the second annular wall 116. The sleeve hole 15 passes through the second annular wall 116 and the annular panel 124. The sleeve hole 15 is used to accommodate the atomizer core 2 of the cartridge structure. The first oil outlet 121 and the sealing rubber plug 14 are located on the annular panel 124 , and the first oil chamber 16 is surrounded by the first annular wall 115 , the second annular wall 116 , the first panel 114 , and the annular panel 124 .

[0055] In one embodiment, a first limiting groove 113 is formed on the outer wall of the second annular wall 116 at an end away from the first panel 114 , and the top surface of the first limiting groove 113 abuts against the annular panel 124 , thereby limiting the first sealing member 12 from continuing to move into the first oil chamber 16 .

[0056] In one embodiment, the circumferential side of the bracket 13 protrudes outward to form a limiting protrusion 132, and the first sealing rubber component 12 also includes a third rubber ring. The third rubber ring is located at the top of the limiting protrusion 132 and the bottom of the second annular wall 116, and cooperates with the top surface of the first limiting groove 113 to abut against the annular panel 124, which can further limit the first sealing rubber component 12 from continuing to move into the first oil chamber 16.

[0057] Based on the above-mentioned oil bottle 1, this embodiment also provides a cigarette cartridge structure.

[0058] Refer to the attached Figure 1-12 The cigarette cartridge structure includes a cigarette cartridge assembly 100 and the oil bottle 1 described above. The cigarette cartridge assembly 100 is provided with a second oil chamber 10 and a first oil inlet hole 32 provided at the top of the second oil chamber 10. The cigarette cartridge assembly 100 is provided with a pusher 31 around the first oil inlet hole 32. When the oil bottle 1 is assembled on the cigarette cartridge assembly 100, the pusher 31 pushes the sealing rubber plug 14 upward to connect the second oil outlet hole 131 with the first oil inlet hole 32. The cigarette oil in the first oil chamber 16 enters the second oil chamber 10 through the first oil outlet hole 121, the second oil outlet hole 131, and the first oil inlet hole 32, thereby adding cigarette oil to the cigarette cartridge, increasing the number of puffs, and extending the service life of the cigarette cartridge structure.

[0059] Specifically, in the above embodiment, the cigarette cartridge assembly 100 includes an atomizer core 2 and an oil storage tank 3, wherein the atomizer core 2 is used to heat the smoke oil to form smoke, and the second oil chamber 10 includes an oil storage chamber 20 and an oil storage chamber 232. Part of the atomizer core 2 is placed in the oil storage tank 3, and the oil storage chamber 20 is located on the outside of the atomizer core 2. The oil storage chamber 20 is arranged on the oil storage tank 3 or is surrounded by the oil storage tank 3 and the atomizer core 2. The first oil inlet hole 32 is located on the top of the oil storage tank 3, and the first oil inlet hole 32 is connected to the oil storage chamber 20. The oil storage chamber 232 is located in the atomizer core 2, and the oil storage chamber 232 is connected to the oil storage chamber 20, that is, the smoke oil can enter the atomizer core 2 through the first oil inlet hole 32 and the oil storage chamber 20 in sequence.

[0060] The atomizer core 2 includes a first atomizer housing 21, a second oil-absorbing cotton 22, a second atomizer housing 23, a first oil-absorbing cotton 24, a heating element 26, a top rubber plug 27, and a bottom rubber plug 25. The second atomizer housing 23 is arranged in the first atomizer housing 21, the second oil-absorbing cotton 22 is located between the first atomizer housing 21 and the second atomizer housing 23, the first oil-absorbing cotton 24 is arranged in the second atomizer housing 23, the heating element 26 is arranged near the bottom of the second oil-absorbing cotton 22, the top rubber plug 27 and the bottom rubber plug 25 are respectively connected to the upper and lower ends of the second atomizer housing 23, and the oil storage chamber 232 is formed by the second atomizer housing 23, the top rubber plug 27, and the bottom rubber plug 25. The first atomizer housing 21 is at least partially placed in the oil passage chamber 20. The first atomizer housing 21 is provided with a second oil inlet hole 211, the second atomizer housing 23 is provided with a third oil inlet hole 231, and the second oil-absorbing cotton 22 is located between the third oil inlet hole 231 and the second oil inlet hole 211. The second absorbent pad 22 guides the smoke from the oil passage chamber 20 through the second oil inlet hole 211 and into the oil storage chamber 232. The second absorbent pad 22 also effectively limits the speed at which the smoke enters the oil storage chamber 232, acting as a flow limiter. This prevents smoke from accumulating on the first absorbent pad 24 and preventing the user from inhaling the smoke into their mouth. Furthermore, the second absorbent pad 22 prevents the smoke from leaking out of the first absorbent pad 24, thus preventing the user from inhaling the smoke.

[0061] A flue is formed on the atomizer core 2, passing through the first oil-absorbing cotton pad 24, the top rubber plug 27, and the bottom rubber plug 25. This allows the vapor generated by the heated liquid in the atomizer core 2 to circulate during inhalation, facilitating inhalation. The bottom rubber plug 25 is provided with a clearance hole 251 for the pins of the heating element 26. This clearance hole 251 allows the heating element 26 to be connected to electricity via pins or wires.

[0062] In one embodiment, the cigarette cartridge assembly 100 further includes a second sealing member 4 , part of which is located between the outer wall of the oil storage bin 3 and the inner wall of the first annular wall 115 , thereby achieving sealing between the bottle body 11 and the oil storage bin 3 and further preventing the leakage of the cigarette oil.
