DETAILED DESCRIPTION

[0027] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Refer to the instruction manual Figure 1-5 The outer cover snap-fit ​​structure used for the ink bottle includes a middle cover, which is installed on the ink bottle body. Generally, the middle cover and the ink bottle body are connected by a threaded connection. The middle cover and the ink bottle body are disassembled and connected together through the threaded connection. At the same time, in order to increase the airtightness between the middle cover and the ink bottle body, a sealing gasket is provided inside the middle cover and a ratchet structure is provided at the end of the middle cover to prevent the middle cover from being accidentally removed.

[0029] The middle cover has a connecting portion 2 and an ink circulation portion 3. The connecting portion 2 is used to connect to the ink bottle body. The ink circulation portion 3 is used to guide the ink in the ink bottle body. A rubber plug 4 is provided in the ink circulation portion 3. When the ink bottle body needs to be inserted into the printer, the ink injection port on the printer will destroy the opening of the rubber plug 4. When the ink injection port is pulled out from the rubber plug 4, since the rubber plug 4 is made of rubber, the opening formed on the rubber plug 4 will automatically close, thereby preliminarily preventing the ink in the ink bottle body from flowing out.

[0030] In order to better enable the rubber plug 4 to be broken and opened by the ink injection port, an auxiliary blade is provided on the rubber plug 4. The auxiliary blade artificially increases the stress point, so that the rubber plug 4 can be broken and opened better and faster.

[0031] The ink flow channel 3 further includes a placement slot for accommodating the rubber plug 4. The placement slot is divided into a connecting slot 10 and a retaining slot 11. An outwardly expanding stepped surface is provided between the connecting slot 10 and the retaining slot 11. The connecting slot 10 communicates with the interior space of the ink bottle body and is in the shape of a trumpet that contracts inward.

[0032] The inward-converging trumpet shape of the connecting groove 10 can better gather the ink in the ink bottle body, and on the other hand, the portion of the rubber plug 4 located in the connecting groove 10 can better fit with the outer wall, thereby increasing the tightness between the rubber plug 4 and the connecting groove 10;

[0033] The outward-expanding stepped surface between the card slot 11 and the connecting slot 10 can support the rubber plug 4 and prevent the rubber plug 4 from falling out into the ink bottle when the rubber plug 4 is inserted into the printer.

[0034] The outer side of the ink circulation part 3 is also provided with a positioning rib 12. When the ink circulation part 3 is inserted into the printer, the ink bottle body can be positioned by the positioning rib 12. At the same time, the positioning rib 12 can also serve the purpose of fixing the ink bottle body in the printer. During the ink filling process, there is no need for staff to support the ink bottle body.

[0035] The ink bottle body further includes an outer cover 1, a middle cover is located between the outer cover 1 and the ink bottle body, the outer cover 1 is installed on the middle cover, and the opening of the middle cover for outflowing ink is blocked by the outer cover 1. A limiting groove 5 is provided on the inner side of the outer cover 1 for use with the outer side of the middle cover connecting part 2, and a limiting block 6 is provided on the outer side of the middle cover connecting part 2 with the same shape as the limiting groove 5 and inserted into the limiting groove 5.

[0036] The middle cover and outer cover 1 are generally cylindrical with an axis. On the one hand, the cylindrical body is easy to process, and on the other hand, it can be better installed. During the installation process, since the inner side of the cylindrical body is a circular ring, it can be easily installed and aligned at any position. At the same time, the limit groove 5 and the limit block 6 are both circular ring-shaped. At the same time, the limit groove 5, the limit block 6, the middle cover and the outer cover 1 are coaxial. The limit block 6 is inserted into the limit groove 5 to limit and fix the middle cover and the outer cover 1.

[0037] The middle cover and the outer cover 1 are also provided with a positioning assembly, which includes a positioning plate 7 and a guide plate 8. There are multiple positioning plates 7 and they are evenly arranged on the outer edge surface of the middle cover, wherein a receiving groove 9 for accommodating the guide plate 8 is formed between two adjacent positioning plates 7. When the outer cover 1 is buckled onto the middle cover, the guide plate 8 is inserted into the receiving groove 9 between the two adjacent positioning plates 7, and the outer cover 1 is positioned and guided by the receiving groove 9 and the guide plate 8.

[0038] The end of the guide plate 8 entering the receiving groove 9 is in the shape of a trumpet that expands outward, and the end of the guide plate 8 inserted into the receiving groove 9 is in the shape of an arc. The arc shape of the guide plate 8 contacts the trumpet shape of the receiving groove 9. The trumpet shape of the receiving groove 9 allows the guide plate 8 to be inserted only into the corresponding receiving groove 9, so that the outer cover 1 can be better installed.

[0039] On the inner side of the outer cover 1, along the diameter direction of the outer cover 1, from outside to inside, there are a positioning ring 13, a sealing ring 14 and a wedge block 15. A plurality of positioning grooves 16 are provided on the positioning ring 13, and the end of the positioning rib 12 on the middle cover can be inserted into the positioning groove 16, which provides a further positioning method for the outer cover 1 during installation. The wedge block 15 is inserted into the opening of the ink circulation part 3 and fits the position of the plug 4. When the outer cover 1 is buckled on the middle cover, the wedge block 15 seals the plug 4 to prevent ink from flowing out of the plug 4 after the plug 4 is opened. At the same time, the sealing ring 14 is arranged corresponding to the opening of the ink circulation part 3 to perform secondary sealing on the outside of the opening of the ink circulation part 3.

[0040] The outer edge surface of the outer cover 1 is provided with a polyhedron splicing structure, which enables the staff to better exert force on the outer cover 1 during use, so that the outer cover 1 can be pulled out from the middle cover more conveniently.

[0041] When the utility model is in use, the middle cover is installed on the ink bottle body by means of a threaded connection, and the outer cover 1 is installed on the middle cover by means of a buckling engagement between the limiting groove 5 and the limiting block 6. When the staff needs to install the ink bottle body in the printer, the staff removes the outer cover 1 from the middle cover through the polyhedron splicing structure and inserts the ink flow portion 3 into the printer. Under the action of the positioning ribs 12, the ink bottle body is positioned and fixed in the printer;

[0042] When the ink circulation portion 3 is inserted into the printer, the printer breaks the auxiliary cutting edge of the rubber plug 4, and the ink in the ink bottle flows into the printer through the broken rubber plug 4 for ink filling. After the ink filling is completed, the staff pulls out the ink bottle and snaps the outer cover 1 onto the middle cover. During the process of snapping the outer cover 1 onto the middle cover, the limiting groove 5 and the limiting block 6 limit the middle cover. At the same time, under the action of the guide plate 8 and the receiving groove 9, the outer cover 1 can be better snapped onto the middle cover.

[0043] After the outer cover 1 is buckled, the positioning rib 12 is inserted into the positioning groove 16, the wedge block 15 is inserted into the opening of the ink circulation part 3, and the sealing ring 14 is buckled on the outside of the opening of the ink circulation part 3, thereby forming a multi-directional seal for the opening of the ink circulation part 3 and improving the sealing performance of the ink bottle body.

[0044] The utility model adopts the structure of the limiting block 6 and the limiting groove 5 to limit the outer cover 1 on the middle cover. On the one hand, compared with the existing processing structure, this structure is more convenient to process. On the other hand, compared with the existing fixing structure of the outer cover 1 and the middle cover, it can be more convenient to disassemble and install.

[0045] The utility model adopts the arrangement of the guide plate 8 and the receiving groove 9, so that during the installation process of the outer cover 1 and the middle cover, the outer cover 1 can fall freely to the appropriate position, without the need for workers to spend a certain amount of time on alignment. At the same time, during the production and assembly process, the installation efficiency of the outer cover 1 can be improved, and the assembly and production time of the ink bottle body can be reduced;

[0046] The utility model adopts the arrangement of the card slot 11 and the connecting slot 10, so that the rubber plug 4 can be better installed in the ink circulation part 3, and the stepped surface between the card slot 11 and the connecting slot 10 can further limit and fix the rubber plug 4;

[0047] The utility model adopts the positioning ring 13, the sealing ring 14 and the wedge block 15 provided in the outer cover 1 to further seal the opening of the ink flow portion 3 in the middle cover, so that the ink bottle body can still ensure better sealing after the rubber plug 4 is broken to prevent ink leakage.
