Obviously, the described embodiments are only a part of the embodiments of the present application.

[0025] Embodiment, a preferred technical scheme of a nicotine solution leak-proof storage device, comprising the following:

[0026] It comprises a nicotine solution storage barrel 1, a perfusion leak-proof end nozzle 2 is arranged on the liquid inlet port of the nicotine solution storage barrel 1; the nicotine solution storage barrel 1 comprises a plastic bracket 11, a protective fence 15 fixedly connected to the upper surface of the plastic bracket 11, and a barrel body 13 placed on the upper surface of the plastic bracket 11 inside the protective fence 15, a discharge valve 12 is arranged on the front bottom end surface of the barrel body 13, and a liquid inlet nozzle 14 is arranged on the top end surface of the barrel body 13;

[0027] The filling leak-proof nozzle 2 includes a connecting tube 26 inserted into the outer ring of the inlet nozzle 14, a middle section sleeve 21 fixed to the upper end face of the connecting tube 26, and an externally threaded tube 22 fixed to the upper end face of the middle section sleeve 21. A cap 23 is screwed onto the outer ring surface of the externally threaded tube 22. A conical sealing ring 25 is embedded in the inner cavity of the middle section sleeve 21. Eight to ten C-shaped elastic support pieces 27 are connected in a ring array on the outer ring surface of the conical sealing ring 25. Six to eight fan-shaped rubber pieces 210 are fixedly connected in a ring array at the bottom port of the conical sealing ring 25. A memory metal strip 28 is embedded and filled inside the fan-shaped rubber pieces 210.

[0028] A sealing ring is fitted on the outer surface of the inlet nozzle 14. The outer surface of the sealing ring is in close contact with the inner wall of the connecting pipe 26. An annular chamber 24 is provided inside the middle sleeve 21 for the conical sealing ring 25 to pass through and be embedded. The top and bottom surfaces of the conical sealing ring 25 are in contact with the inner end face of the annular chamber 24, respectively. The outer surface of the external threaded pipe 22 is provided with threads. The inner wall of the cap 23 is provided with threads that are compatible with the threads. The C-shaped elastic support pieces 27 are all C-shaped. The arc surface of the C-shaped elastic support piece 27 is in contact with the outer surface of the conical sealing ring 25. The end of the C-shaped elastic support piece 27 away from the conical sealing ring 25 is fixedly connected to the inner wall of the annular chamber 24. The vertical section of the conical sealing ring 25 is conical. The diameter of the top port of the conical sealing ring 25 is larger than the diameter of the bottom port. The inside of the fan-shaped rubber sheet 210 is provided with a cavity 29. The memory metal strip 28 is embedded and filled inside the cavity 29.

[0029] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0030] After unscrewing cap 23 from external threaded tube 22, insert the conduit for delivering nicotine solution into the middle sleeve 21. The end of the conduit will pry open the gap between the fan-shaped rubber sheets 210 until the conduit enters the inner cavity of the barrel 13. At this time, the elasticity of the C-shaped elastic support sheet 27 forces the conical sealing ring 25 to deform inward, and the conical shape of the conical sealing ring 25 ensures that the inner surface of the conical sealing ring 25 is in close contact with the outer surface of the conduit, thus sealing the liquid inlet channel. After the conduit has filled the inside of the barrel 13, it is pulled out of the barrel 13. At this time, the fan-shaped rubber sheets 210 will quickly return to their contact state due to the elasticity of the shape memory metal strip 28, thereby blocking the channel between the filling leak-proof nozzle 2 and the barrel 13 and preventing the nicotine solution from evaporating due to failure to seal in time.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
