Description

Technical Field

[0001] This utility model relates to the field of printer accessories technology, specifically a printer ink cartridge that is easy to replace. Background Technology

[0002] Ink cartridges are ink storage containers inside printers, connected to the printhead via conduits. They are commonly found in ink tank / continuous ink supply printers. Their main functions are to continuously and stably supply ink to the printhead, balance air pressure to prevent ink leakage, and store spare ink.

[0003] In existing continuous ink supply (CISP) printers, several large-capacity ink bottles are placed outside the printer. These bottles are connected to the ink cartridges via thin, flexible silicone tubes. After a period of use, issues such as poor ink supply, broken print lines, and ink leakage may occur, necessitating cartridge replacement. To avoid deformation or poor sealing of the silicone tube due to repeated insertion and removal or physical stress, the connection between the silicone tube and the ink cartridge is typically cut with scissors. The shortened silicone tube is then connected to the new ink cartridge. While this method is simple, repeated cartridge replacements exacerbate the problem by shortening the silicone tube. Although a relatively long silicone tube is usually provided, its length is limited to prevent excessively long tubes from hindering printer operation. Therefore, repeated cutting of the silicone tube leads to insufficient tube length, requiring replacement. Furthermore, cutting the silicone tube requires scissors. To further simplify cartridge replacement, a more convenient printer ink cartridge replacement method is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a printer ink cartridge that is easy to replace, in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a printer ink cartridge that is easy to replace, comprising an ink cartridge assembly consisting of an ink cartridge body, an inlet nozzle, and an outlet nozzle. The inlet nozzle and the outlet nozzle are respectively fixed to the upper and lower ends of the ink cartridge body and communicate with the inner cavity of the ink cartridge body. Four fixing plates are fixed to the top of the ink cartridge body. The four fixing plates are arranged in pairs and symmetrically distributed with the inlet nozzle as the center. A slot is provided on the side of the fixing plates that is far apart from each other near the bottom.

[0006] The ink cartridge body is connected to a quick-connect assembly via a fixing plate and a slot, and the quick-connect assembly is used to communicate with an external ink bottle.

[0007] The quick-installation component includes a docking unit, a locking unit, and an exit unit;

[0008] The docking unit is connected to the inlet nozzle to enable communication between the ink cartridge body and the external ink bottle.

[0009] The locking unit is used to realize the connection and fixation between the docking unit and the ink sac body;

[0010] During the process of the locking unit releasing the connection with the ink sac body, the withdrawal unit is used to realize the mutual separation between the docking unit and the liquid inlet nozzle.

[0011] As a further solution of the present utility model: The docking unit includes a middle-shaped seat, an upper connecting pipe, a lower connecting pipe, and a flexible pipe;

[0030] 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.

[0031] Please see Figures 1-3 In this embodiment of the present invention, a printer ink cartridge that is easy to replace includes an ink cartridge assembly 1 consisting of an ink cartridge body 101, an inlet nozzle 102, and an outlet nozzle 103. The inlet nozzle 102 and the outlet nozzle 103 are respectively fixed to the upper and lower ends of the ink cartridge body 101 and communicate with the inner cavity of the ink cartridge body 101. Four fixing plates 104 are fixed on the top of the ink cartridge body 101. The four fixing plates 104 are arranged in pairs and symmetrically distributed with the inlet nozzle 102 as the center. A slot 105 is provided on the side of the fixing plates 104 that is far away from each other and near the bottom.

[0032] The ink cartridge body 101 is connected to a quick-release assembly 2 via a fixing plate 104 and a slot 105. The quick-release assembly 2 is used to communicate with an external ink bottle.

[0033] Quick-installation component 2 includes a docking unit, a locking unit, and an exit unit;

[0034] The docking unit is connected to the inlet nozzle 102 to enable communication between the ink cartridge body 101 and the external ink bottle;

[0035] The locking unit is used to fix the docking unit to the ink cartridge body 101;

[0036] During the process of the locking unit being disconnected from the ink cartridge body 101, the exit unit is used to move the docking unit and the inlet nozzle 102 away from each other.

[0037] The docking unit includes a Chinese-shaped base 201, an upper connecting pipe 202, a lower connecting pipe 203, and a flexible hose 204;

[0038] The upper connecting pipe 202 and the lower connecting pipe 203 are fixed to the upper and lower ends of the Chinese character-shaped base 201, respectively, and the upper connecting pipe 202 and the lower connecting pipe 203 are interconnected. The two ends of the flexible tube 204 are connected to the upper connecting pipe 202 and the external ink bottle, respectively.

[0039] The two sides of the Chinese character-shaped base 201 are snapped into the middle of the two sets of fixing plates 104, and the lower connecting tube 203 is sleeved on the outside of the liquid inlet 102 to realize the communication between the ink cartridge body 101 and the external ink bottle.

[0040] The locking unit includes a convex flap 205, a triangular locking block 206, a transverse pull block 207, a groove 208, and a torsion spring 209;

[0041] There are two convex flaps 205. The two convex flaps 205 are rotatably connected to the two sides of the Chinese character-shaped base 201 and distributed on the side of the two sets of fixed plates 104 that are far apart from each other.

[0042] The triangular block 206 is fixed to the bottom of one side of the convex flap 205, and the triangular block 206 is engaged in the inner side of the slot 105 to realize the limiting and fixing of the Chinese character base 201 and the fixing plate 104. The horizontal pull block 207 is fixed to the top of the other side of the convex flap 205.

[0043] The grooves 208 are symmetrically opened on both sides of the top of the Chinese character-shaped base 201. The torsion springs 209 are distributed inside the grooves 208 and sleeved on the outside of the rotating shaft of the triangular block 206. The two ends of the torsion springs 209 are respectively attached to the side of the upper half of the convex flap 205 near the Chinese character-shaped base 201 and the bottom of the inner wall of the groove 208. The torsion springs 209 are used to provide a thrust to the upper half of the convex flap 205 away from the Chinese character-shaped base 201.

[0044] The exit unit includes a 7-shaped pressure block 210, a straight slot 211, and a limit rod 212;

[0045] The vertical part of the 7-shaped pressure block 210 extends from the top of the Chinese character-shaped base 201 to the bottom of the Chinese character-shaped base 201. The side of the horizontal part of the 7-shaped pressure block 210 is close to the upper half of the convex flap 205. The Chinese character-shaped base 201 has a square slot for the vertical part of the 7-shaped pressure block 210 to slide vertically.

[0046] The straight slot 211 is opened at the front end of the vertical part of the 7-shaped pressure block 210 and extends completely to the rear end of the vertical part. The limiting rod 212 passes through the front end of the Chinese character-shaped seat 201 and the square slot. The straight slot 211 is sleeved on the outside of the limiting rod 212.

[0047] When the upper half of the convex flap 205 rotates toward the center of the Chinese character-shaped seat 201 and presses the horizontal part of the 7-shaped pressure block 210, the 7-shaped pressure block 210 moves downward and the bottom of the vertical part presses against the upper surface of the ink cartridge body 101, so as to realize that the Chinese character-shaped seat 201, the upper connecting tube 202, the lower connecting tube 203 and the ink inlet nozzle 102 are separated from each other.

[0048] In this embodiment, it should be noted that the ink cartridge assembly 1 is the i3200 ink cartridge commonly found on the market.

[0049] The procedure for replacing ink cartridge assembly 1 is as follows:

[0050] First, remove the ink cartridge assembly 1 from the mounting bracket on the printer (it should be noted that the insertion structure between the ink cartridge assembly 1 and the mounting bracket on the printer is existing technology and will not be described in detail here). Then, manually pinch the upper half of the two convex flaps 205 together, causing them to flip towards the center of the Chinese character base 201. At this time, the convex flaps 205 flip upward and drive the triangular locking block 206 to rotate and move away from the locking slot 105, thus releasing the connection between the convex flaps 205 and the fixing plate 104.

[0051] Next, a flipping and pressing force is applied to the upper half of the convex flap 205. At this time, the upper half of the convex flap 205 contacts the horizontal part of the 7-shaped pressure block 210 and forms a pressure on it. This pressing force causes the 7-shaped pressure block 210 to move downward as a whole (it should be noted that the limiting rod 212 limits the vertical movement of the 7-shaped pressure block 210). The bottom of the vertical part of the 7-shaped pressure block 210 presses against the top of the ink sac body 101, and the pressing force acts in the opposite direction on the 7-shaped pressure block. The pressure block 210 is transferred to the center-shaped seat 201, causing the center-shaped seat 201, the upper connecting pipe 202, the lower connecting pipe 203, and the convex flap 205 to move upward relative to the 7-shaped pressure block 210. This causes the lower connecting pipe 203 to move upward along the liquid inlet 102, thereby reducing the contact area between the lower connecting pipe 203 and the liquid inlet 102. When an upward pulling force is applied to the quick-release assembly 2 as a whole, the lower connecting pipe 203 can be easily separated from the liquid inlet 102.

[0052] When installing the new ink cartridge assembly 1, simply align the lower connecting tube 203 with the inlet nozzle 102 and the center-shaped base 201 with the middle position of the two sets of fixing plates 104 and insert it downwards. The operation is simple and convenient.

[0053] The quick-release assembly 2 can be easily disassembled by the cooperation of the above-mentioned parts, so that when replacing the ink cartridge assembly 1, there is no need to cut the hose 204, which further simplifies the ink cartridge replacement operation. At the same time, it avoids the situation where the hose length becomes shorter due to multiple cutting of the hose and the hose needs to be replaced.

[0054] Please refer to this carefully. Figures 1-3 The horizontal part of the 7-shaped pressure block 210 is close to the convex flap 205 but does not contact the vertical convex flap 205.

[0055] In this embodiment: This structure allows the 7-shaped pressure block 210 to flip without affecting the convex flap 205, which in turn drives the triangular card block 206 away from the card slot 105.

[0056] Please refer to this carefully. Figures 1-3 The inner wall of the lower connecting pipe 203 is provided with a sealing element, and the hose 204 is interference-fitted with the upper connecting pipe 202.

[0057] In this embodiment, this structure is used to ensure the sealing of the connection between the lower connecting pipe 203 and the inlet nozzle 102, and between the hose 204 and the upper connecting pipe 202.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
