Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 3The ink cartridge protective cover shown includes a base 10 and a baffle 11 extending vertically from one end of the base 10. Foam 15 is provided on the base 10 to seal and block the ink outlet 23 of the ink cartridge 20. A snap-fit ​​handle 14 is also provided at the upper end of the baffle 11, located above the base 10. One end of the snap-fit ​​handle 14 is tilted upwards for easy manipulation. The ink cartridge 20 is installed and fixed in the area between the base 10, the baffle 11, and the snap-fit ​​handle 14. Two retaining plates 13 are also provided on the base 10 near the baffle 11. Located on both sides of the base 10 along the X direction, the clamping plate 13 has a guide surface 131 extending obliquely from top to bottom. When installing the ink cartridge 20, the positioning pin 22 on the ink cartridge 20 slides into the inner side of the clamping plate 13 from the obliquely extending guide surface 131 and makes the side of the ink cartridge 20 abut against the baffle 11. After installation, the ink outlet 23 at the bottom of the ink cartridge 20 is pressed and sealed on the foam cotton 15, and the protrusion 21 at the top of the ink cartridge 20 is snapped and fixed with the snap handle 14, thereby connecting and fixing the ink cartridge 20 to the ink cartridge protective cover, avoiding the problem of ink leakage or ink splashing caused by the ink cartridge 20 shaking. When removing the ink cartridge 20, simply pry the latching handle 14 to separate the protrusion 21 on the ink cartridge 20 from the latching handle 14. This will allow the ink cartridge 20 to tilt relative to the base 10 / foam 15, and external air will gradually enter from the air vent at the bottom of the ink cartridge 20 to balance the pressure inside the ink cartridge 20, preventing ink overflow or splashing and improving the user experience.

[0019] In some possible embodiments, side plates 12 are formed on both opposite sides of the base 10. The side plates 12 extend vertically to their two ends and connect the base 10 and the baffle 11 respectively. A retaining plate 13 is formed on the inner side of the baffle 11, that is, the ink cartridge 20 is installed and fixed between the two side plates 12.

[0020] In some possible embodiments, a first limiting rib 101 is formed on the inner side of both side plates 12. The distance between the two first limiting ribs 101 is adapted to the width of the ink cartridge 20. After the ink cartridge 20 is installed, the two first limiting ribs 101 cooperate to constrain the degree of freedom of the ink cartridge 20 in the X direction.

[0021] In some possible embodiments, a second limiting rib 102 is formed on the lower end face of the snap handle 14. The distance between the second limiting rib 102 and the foam 15 is adapted to the height dimension of the ink cartridge 20. After the ink cartridge 20 is installed, the foam 15 is compressed and it cooperates with the second limiting rib 102 to constrain the degree of freedom of the ink cartridge 20 in the Z direction.

[0022] In some possible embodiments, a third limiting rib 103 is formed on the inner side of the baffle 11. The distance between the third limiting rib 103 and the inner end face of the clamping plate 13 is adapted to the distance between the far side of the positioning pin 22 on the ink cartridge 20 and the side of the ink cartridge 20. After the ink cartridge 20 is installed, the third limiting rib 103 cooperates with the inner end face of the clamping plate 13 to constrain the degree of freedom of the ink cartridge 20 in the Y direction.

[0023] In some possible embodiments, the card plate 13 protrudes from the inside of the side plate 12 along the X direction and then bends to extend along the Y direction on the base 10 to form a reinforcing rib 132, thereby enhancing the connection strength between the base 10 and the side plate 12.

[0024] In some possible embodiments, the foam 15 is elongated and extends along the Y direction. The foam 15 can be glued and fixed to the base 10. When the ink cartridge 20 is installed, the ink outlet 23 at its bottom gradually approaches and presses against the foam 15. When the ink cartridge 20 is removed, the ink outlet 23 also gradually moves away from the foam 15. External air gradually enters from the air vent at the bottom of the ink cartridge 20 to balance the pressure inside the ink cartridge 20. It should be noted that the ink cartridge 20 to which the ink cartridge protective cover of this utility model is applicable has the ink outlet 23 located at the bottom of the ink cartridge 20, and the air vent is located on the side of the ink outlet 23 away from the baffle 11.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
