[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.
[0022] Referring to Figures 1-4 A double-layer annular sealing structure of an ink bottle, comprising a bottle body 1, a bottle nozzle 2 is installed at the top of the bottle body 1, and a detachable bottle cap 3 is assembled on the top of the bottle nozzle 2 by thread engagement. A cylindrical nozzle 22 is fixedly arranged at the top of the bottle nozzle 2, an inner hole 23 is arranged in the cylindrical nozzle 22, and a sealing inner ring 32 and a sealing outer ring 33 adapted to the cylindrical nozzle 22 are arranged in the bottle cap 3.
[0023] The outer wall of the bottle mouth 2 is provided with an outer thread 21, the inner wall of the bottle cap 3 is provided with an inner thread 31, and the outer thread 21 and the inner thread 31 are adapted to engage. The outer thread 21 and the inner thread 31 are both more than 2 circles of progressive thread to assist in compression, and the installation effect of the bottle cap 3 can be ensured through the engagement between the outer thread 21 and the inner thread 31.
[0024] The cylindrical nozzle 22 is a hollow cylinder, and the hollow inner wall inside is an inner hole 23. After the bottle cap 3 is removed, the ink inside the bottle body 1 can be poured out through the cylindrical nozzle 22.
[0025] The sealing inner ring 32 and the sealing outer ring 33 are both installed on the bottle cap 3, and when the bottle cap 3 is installed on the bottle mouth 2, the sealing inner ring 32 and the sealing outer ring 33 are respectively in interference fit with the inner hole 23 and the cylindrical nozzle 22, the double-ring spacing forms an annular sealed air chamber, and the size of the annular sealed air chamber is 3*2.3mm. With the assistance of the cavity air pressure in the annular sealed air chamber formed by the double-ring spacing, the sealing effect of the ink can be further improved to prevent ink leakage or evaporation.
[0026] The sealing inner ring 32 is inverted conical, and the outer wall of the sealing inner ring 32 is in interference fit with the inner hole 23. When the bottle cap 3 is capped, the axial compression seal formed between the sealing inner ring 32 and the inner hole 23 can prevent ink from leaking from the bottle body 1.
[0027] The sealing outer ring 33 is inverted conical, and the inner wall of the sealing outer ring 33 is in interference fit with the outer wall of the cylindrical nozzle 22. When the bottle cap 3 is capped, the radial compression seal formed between the sealing outer ring 33 and the cylindrical nozzle 22 can prevent ink from evaporating from the bottle body 1.
[0028] In this embodiment, when the user needs to pour out the ink, the bottle cap 3 only needs to be rotated to loosen the engagement of the outer thread 21 and the inner thread 31, and then the bottle cap 3 only needs to be removed, so that the ink inside the bottle body 1 can be poured out through the cylindrical nozzle 22.
[0029] Further, when the user needs to cap the bottle cap 3, the bottle cap 3 only needs to be installed on the bottle mouth 2 by rotating through the engagement of the outer thread 21 and the inner thread 31. During the installation of the bottle cap 3, the outer wall of the sealing inner ring 32 on the bottle cap 3 is in interference fit with the inner hole 23, and the inner wall of the sealing outer ring 33 is in interference fit with the outer wall of the cylindrical nozzle 22.
[0030] In this way, the ink can be prevented from leaking out of the bottle 1 by the axial compression seal formed between the sealing inner ring 32 and the inner hole 23, and the ink can be prevented from evaporating out of the bottle 1 by the radial compression seal formed between the sealing outer ring 33 and the cylindrical nozzle 22. Finally, the sealing effect on the ink can be further improved by the auxiliary cavity air pressure in the annular sealing air chamber formed by the double-ring spacing, so as to prevent the ink from leaking or evaporating.
[0031] In this way, the ink bottle does not need to be provided with a sealing film, and the sealing film process is omitted. Moreover, the sealing film does not need to be provided, and the sealing film residue cannot be mixed into the ink. In addition, the sealing performance can be guaranteed during repeated opening and closing during use, so as to delay the oxidation and evaporation of the ink. Moreover, the double-layer sealing structure can effectively avoid the problem of elastic failure of a single-layer silica gel sealing ring structure after long-term use.
[0032] In the utility model, the sealing inner ring 32 and the sealing outer ring 33 are respectively in interference fit with the inner hole 23 and the cylindrical nozzle 22, and an annular sealing air chamber is formed between the double rings. The sealing effect on the ink can be further improved by the auxiliary cavity air pressure in the sealing air chamber, so as to delay the oxidation and evaporation of the ink. Moreover, the double-layer sealing structure can effectively avoid the problem of elastic failure of a single-layer silica gel sealing ring structure after long-term use.
[0033] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all should be covered in the protection scope of the utility model.
