[0027] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments: Example

[0028] See Figures 1-8 This embodiment provides an ink supply cartridge 100 for supplying ink to an ink cartridge (not shown). The ink supply cartridge 100 includes a cartridge body 10, an ink inlet 20, an ink outlet 30, a movable part 40, a sealing part 50, and a buoyancy part 60, which are described in detail below.

[0029] The box body 10 is cuboid in shape, and its inner cavity 11 contains ink. The inner cavity 11 is provided with a first connection port 111 and a second connection port 112 at intervals along the length direction.

[0030] The ink inlet 20 is connected to the first connection port 111. Specifically, the fixing seat 24 is installed in the first connection port 111. After the sealing plug 23 is installed in the fixing seat 24, the main body of the ink inlet 20 is inserted into the sealing plug 23. Then, the fixing cover 25 is fixedly connected to the fixing seat 24 using screws or other fasteners. In this way, the ink inlet 20 is connected to the first connection port 111. The sealing cavity 21 of the ink inlet 20 is accommodated in the lower part of the inner cavity 11.

[0031] The ink outlet 30 is connected to the second connection port 112. Specifically, the ink outlet 30 is inserted into the second connection port 112 and is press-fitted with the second connection port 112, thus completing the connection of the ink outlet 30 to the second connection port 112.

[0032] The movable part 40 is slidably connected to the cavity wall of the sealing cavity 21 of the ink inlet part 20. Specifically, the sealing cavity 21 is provided with a sliding column 21a, and the movable part 40 is provided with a corresponding sliding track 41. The sliding column 21a slides along the sliding track 41 to realize the slidable connection between the movable part 40 and the sealing cavity 21.

[0033] The sealing part 50 is connected to the movable part 40 to seal the ink inlet and outlet 22 of the ink inlet part 20. Specifically, the sealing part 50 is provided with a connecting cavity 51, and the end of the movable part 40 is provided with a connecting buckle 43. The connecting buckle 43 is fastened into the connecting cavity 51 to fix the sealing part 50 to the end of the movable part 40.

[0034] The buoyancy part 60 includes a drive part 61 and a buoyancy part 62. The drive part 61 is rotatably connected to the sealed cavity 21, and one end of the drive part 61 is inserted into the receiving cavity 42 of the movable part 40. The other end of the drive part 61 is connected to the buoyancy part 62. The outer surface of the buoyancy part 62 is provided with a drag-reducing part 621.

[0035] Using the aforementioned ink cartridge 100, ink is poured from the ink inlet 20 into the inner cavity 11 of the cartridge body 10. The buoyancy part 62 rises as the ink volume increases, causing the drive part 61 to rotate in the sealed cavity 21. One end of the drive part 61 drives the movable part 40 to slide on the cavity wall of the sealed cavity 21, thereby driving the sealing part 50 connected to the movable part 40 to block the ink inlet outlet 22 of the ink inlet 20, thus sealing the ink inlet outlet 22 of the ink inlet 20. Furthermore, since the outer surface of the buoyancy part 62 is provided with a drag-reducing part 621, the drag-reducing part 621 reduces the contact area between the buoyancy part 62 and the inner wall of the inner cavity 11. That is, the inner wall of the inner cavity 11 has little resistance to the floating of the buoyancy part 62, and the floating sensitivity of the buoyancy part 62 is high. After floating, it can effectively drive the sealing part 50 to seal the ink inlet outlet 22 of the ink inlet 20, effectively preventing ink from overflowing from the ink inlet 20, saving energy and protecting the environment, and ensuring smooth ink supply.

[0036] In this embodiment, preferably, the drag reduction part 621 consists of N protrusions 621a disposed on the outer surface of the buoyancy part 62, wherein N is greater than 0 and N is a natural number, and preferably the protrusions 621a are generally hemispherical; with N protrusions 621a disposed in this way, during the upward floating process of the buoyancy part 62, only the protrusions 621a contact the inner wall of the inner cavity 11, which can effectively achieve the drag reduction effect.

[0037] More preferably, N protrusions 621a are arranged around the outer peripheral surface of the buoyancy part 62, wherein N is greater than 1. Preferably, the N protrusions 621a are evenly arranged around the outer peripheral surface of the buoyancy part 62. This arrangement can evenly reduce the contact resistance between the outer peripheral surface of the buoyancy part 62 and the inner wall of the inner cavity 11, making the buoyancy part 62 float more sensitively and stably.

[0038] In this embodiment, a partition plate 113 is provided in the inner cavity 11, which divides the inner cavity 11 into an ink inlet cavity 11a and an ink outlet cavity 11b. The partition plate 113 has a connecting port 113a that connects the ink inlet cavity 11a and the ink outlet cavity 11b. The ink inlet part 20 is connected to the ink inlet cavity 11a, and the ink outlet part 30 is connected to the ink outlet cavity 11b. The partition plate 113 in the inner cavity 11 enhances the structural strength of the inner cavity 11 and can prevent the inner cavity 11 from deforming. Moreover, the partition plate 113 divides the inner cavity 11 into an ink inlet cavity 11a and an ink outlet cavity 11b, which is conducive to the smooth operation of ink inlet and ink supply.

[0039] Preferably, the connecting port 113a of the partition plate 113 is in the form of a grid. The grid-shaped connecting port 113a can prevent the partition plate 113 from deforming under force. At the same time, during the process of ink flowing from the ink inlet chamber 11a to the ink outlet chamber 11b in the inner cavity 11, the grid-shaped connecting port 113a plays the role of filtering ink impurities.

[0040] In this embodiment, the length of the ink inlet cavity 11a is longer than that of the ink outlet cavity 11b. The ink inlet cavity 11a has enough space to accommodate the buoyancy part 60, so that the buoyancy part 62 of the buoyancy part 60 can be set long enough to increase the buoyancy of the buoyancy part 62 and make the buoyancy part 62 float more sensitively.

[0041] Preferably, in the upright state of the ink supply cartridge 100, the bottom wall of the ink inlet cavity 11a is set as a downward slope wall facing the partition plate 113. This setting allows the ink in the inner cavity 11 to flow from the ink inlet cavity 11a along the downward slope wall to the ink outlet cavity 11b, which is conducive to completing the ink supply smoothly and has a good ink supply effect.

[0042] In this embodiment, when the ink cartridge 100 is in an upright state, the first connection port 111 and the second connection port 112 are located on the top wall 11-1 of the cartridge body 10, or the first connection port 111 is located on the top wall 11-1 of the cartridge body 10, and the second connection port 112 is located on the side wall 11-2 of the cartridge body 10. With the above configuration, the position of the second connection port 112 connected to the ink outlet 30 can be flexibly adjusted to meet various usage needs and improve the usage effect.

[0043] In this embodiment, preferably, the side wall 11-2 is provided with a positioning hole 114. When the ink supply box 100 is in an upright state, the positioning hole 114 is located below the second connection port 112. The positioning hole 114 is used to perform assembly positioning when the various components of the ink supply box 100 are assembled, and at the same time, it is used to keep the ink supply box 100 in an upright state during the ink supply process to achieve stable ink supply.

[0044] In this embodiment, the drive part 61 is provided with a rotating shaft 611, which is rotatably connected to the shaft hole 21b of the sealing cavity 21. In the upright state of the ink supply cartridge 100, the end of the drive part 61 inserted into the receiving cavity 42 of the movable part 40 is located on the same side of the vertical center line 611a of the rotating shaft 611 with the buoyancy part 62. If the structure of the buoyancy part 60 is cleverly designed, the buoyancy part 62 floats up and powerfully drives the end of the drive part 61 inserted into the receiving cavity 42 of the movable part 40 to move upward, so that the sealing part 50 moves upward to effectively seal the ink inlet outlet 22 of the ink inlet part 20 and prevent ink from overflowing backward from the ink inlet outlet 22.

[0045] Finally, it should be noted that the above description is merely the preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible changes and simple substitutions to the technical solution of this utility model using the disclosed methods and technical content without departing from the scope of the technical solution of this utility model, and these all fall within the protection scope of the technical solution of this utility model.
