Description

Technical Field

[0001] The utility model belongs to the technical field of e-liquid containers, and particularly refers to a bottle stopper. Background Art

[0002] E-liquid bottles on the market include a bottle body and an outer cap. The bottle body is provided with an external thread, and the outer cap is provided with an internal thread adapted to the external thread. To facilitate filling e-liquid into an electronic cigarette, it is necessary to replace the outer cap with a bottle stopper so that the e-liquid can be dropped into the filling area orderly and accurately.

[0003] As disclosed in a Chinese patent with publication number CN107697449B, an inner stopper includes a nozzle, a plug cover and a plug cap. The plug cover is provided with a through hole. One end of the nozzle is fixed to the plug cover, and the other end of the nozzle extends out of the plug cover. The plug cap is fixed to the plug cover, and the outer peripheral surface of the plug cap is provided with stripes for sealing. The nozzle is provided with a liquid outlet hole penetrating through the nozzle. The liquid outlet hole is communicated with the through hole, and a stepped opening is provided at the connection between the liquid outlet hole and the through hole. The size of the stepped opening is smaller than that of the liquid outlet hole.

[0004] The above inner stopper is inserted and matched with the bottle mouth of the dropper bottle, so that a relatively sealed environment is formed inside the inner stopper and the dropper bottle body. The e-liquid in the dropper bottle can directly drop from the liquid outlet hole into the filling port of the electronic cigarette, and the excess oil adhering to the inner wall of the nozzle is sucked back into the bottle body under the action of atmospheric pressure to prevent oil spillage. However, the above inner stopper is of an integral structure, and such a structure is not convenient for adding other flavors of e-liquid into the bottle body, and the practicability is relatively poor. In addition, if the liquid outlet hole is blocked, the entire e-liquid stopper needs to be taken out for cleaning, which is inconvenient to operate. Summary of the Utility Model

A liquid outlet nozzle is detachably arranged on the liquid inlet. The liquid outlet nozzle is connected to the plug cover through a flexible connecting piece, and a liquid outlet hole communicating with the liquid inlet is provided on the liquid outlet nozzle.

[0008] In the above bottle stopper, a limiting sealing ring is formed by downward extension of the liquid inlet. A sealing ring groove is formed on the inner side surface of the limiting sealing ring. A sealing convex ring for cooperating with the sealing ring groove is provided at the lower end of the liquid outlet nozzle.

[0009] In the above bottle stopper, an anti-detachment ring is provided on the outer peripheral side of the lower end of the liquid outlet nozzle. The anti-detachment ring is clamped at the lower end of the limiting sealing ring after passing through the sealing ring groove.

[0010] In the above-mentioned bottle stopper, a sealing ring is arranged on the periphery of the liquid outlet nozzle, and a first receiving groove for receiving the sealing ring is arranged on the plug cover.

[0011] In the above-mentioned bottle stopper, the limiting sealing ring is of a conical cylinder structure, and its small end is arranged downward.

[0012] In the above-mentioned bottle stopper, a sealing space is left between the liquid outlet nozzle and the limiting sealing ring.

[0013] In the above-mentioned bottle stopper, the flexible connecting piece is provided with a deformation section, and the thickness of the deformation section is smaller than that of the flexible connecting piece.

[0014] In the above-mentioned bottle stopper, a second receiving groove for receiving the flexible connecting piece is arranged on the plug cover.

[0015] In the above-mentioned bottle stopper, there are two deformation sections, which are respectively arranged close to the plug cover and the liquid outlet nozzle.

[0016] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0017] The plug cover of the present utility model is used to connect to the bottle mouth of the e-liquid bottle. The plug cover and the liquid outlet nozzle are connected by a flexible connecting piece, so as to avoid the problems of the liquid outlet nozzle falling off and being polluted, and also avoid the possibility of the liquid outlet nozzle being lost. The limiting sealing ring, the sealing convex ring and the anti-detachment ring arranged between the liquid outlet nozzle and the plug cover are used to ensure the tight connection between the liquid outlet nozzle and the plug cover. The designed anti-detachment ring further ensures the connection stability between the liquid outlet nozzle and the plug cover. Brief Description of the Drawings

[0023] The present utility model will be further described below with specific embodiments in conjunction with the drawings:

[0024] like Figures 1 - 4 As shown: a bottle stopper, comprising a stopper cover 1 connected to a bottle mouth, a liquid inlet 11 being provided at the middle end portion of the stopper cover 1, a liquid outlet nozzle 12 being detachably provided on the liquid inlet 11, the liquid outlet nozzle 12 being connected to the stopper cover 1 via a flexible connector 13, and a liquid outlet hole 14 communicating with the liquid inlet 11 being provided on the liquid outlet nozzle 12. Specifically, the liquid inlet is designed to facilitate the addition of e-liquid, and the stopper cover and the liquid outlet nozzle are connected via a flexible connector, in order to avoid the problem of the liquid outlet nozzle falling off and being contaminated, and also to avoid the possibility of the liquid outlet nozzle being lost.

[0025] In the above-mentioned bottle stopper, the liquid inlet 11 extends downward to form a limiting sealing ring 15, and the inner side surface of the limiting sealing ring 15 is formed with a sealing ring groove 151. The lower end of the liquid outlet nozzle 12 is provided with a sealing convex ring 121 used in conjunction with the sealing ring groove 151. Specifically, the designed sealing ring groove and sealing convex ring are intended to improve the sealing performance between the liquid outlet nozzle and the plug cover to avoid oil leakage.

[0026] In the above-mentioned bottle stopper, an anti-slip ring 122 is provided on the outer peripheral side of the lower end of the liquid outlet nozzle 12. The anti-slip ring 122 passes through the sealing ring groove 151 and is clamped on the lower end of the limiting sealing ring 15. Specifically, this is to prevent the liquid outlet nozzle from detaching from the plug cover. The designed liquid outlet nozzle has a long mouth. When the liquid inlet needs to be opened, it is only necessary to pinch the long mouth and pry it open. By using a lever principle, the liquid outlet nozzle can be pried open and detached from the plug cover, making it convenient to add tobacco oil into the bottle body. The anti-slip ring and the limiting sealing ring are interference fit.

[0027] In the bottle stopper mentioned above, a sealing ring 123 is arranged on the peripheral side of the liquid outlet nozzle 12, and a receiving groove 16 for receiving the sealing ring 123 is arranged on the stopper cover 1. Specifically, the designed sealing ring can also play a certain sealing role.

[0028] In the bottle stopper described above, the limiting sealing ring 15 is a conical cylindrical structure, and its small end is arranged downwards, specifically, in order to facilitate the use with the lower end of the liquid outlet nozzle.

[0029] In the bottle stopper described above, a sealing space 124 is reserved between the liquid outlet nozzle 12 and the limiting sealing ring 15. Specifically, this is to further improve the sealing performance.

[0030] In the above-mentioned bottle stopper, the flexible connecting member 13 is provided with a deformation section 131, the thickness of the deformation section 131 is smaller than that of the flexible connecting member 13, there are two deformation sections 131, and they are respectively arranged near the plug cap 1 and the liquid outlet nozzle 12. Specifically, this is to facilitate the deformation of the deformation section 131 when the liquid outlet nozzle is connected to the plug cap, so that the sealing ring 123 can sink and enter the first receiving groove 16, ensuring the connection sealing performance between the liquid outlet nozzle and the plug cap.

[0031] In the above-mentioned bottle stopper, the plug cap 1 is provided with a second receiving groove 132 for receiving the flexible connecting member 13. Specifically, this can save materials while ensuring the connection between the two and avoiding excessive exposure of the flexible connecting member.

[0032] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
