Description

Technical Field

[0001] This application relates to the technical field of ink refilling for inkjet printers, and more particularly to an ink refilling device for an inkjet printer. Background Technology

[0002] Inkjet printers typically have internal ink cartridges, which eventually run out of ink after a period of use, requiring refilling. Current refilling methods usually involve using a syringe: first, the cartridge's sealing plug is removed, then a syringe inserts a syringe into the cartridge, and finally, ink is pushed in. However, this operation requires a certain level of skill; otherwise, refilling may fail, or the syringe may puncture the ink cartridge, damaging it. Therefore, to address these issues, this application provides an ink refilling device for inkjet printers. Utility Model Content

[0003] To address the aforementioned problems, this application provides an ink injection device for an inkjet printer.

[0004] This application provides an ink filling device for an inkjet printer, including an L-shaped base plate and a back plate, with an ink tank fixed on the back plate and a positioning structure provided on the base plate for fixing the position of the ink tank.

[0005] A tube is movably installed at the top of the back panel, corresponding to the ink cartridge filling port, and the tube moves along its axis. A filling mechanism is installed between the tube and the ink tank, and ink in the ink tank is discharged into the ink cartridge through the tube.

[0006] The ink tank also has its own ink extraction structure.

[0007] The ink cartridge is fixed in position by setting a positioning structure, and an axially movable tube is set on the back plate. At the same time, the tube works with the filling mechanism to draw ink from the ink tank and enter the ink cartridge through the tube, thus completing the filling operation conveniently. Meanwhile, since both ends of the tube are set with limiters, it can effectively avoid excessive insertion and damage to the ink cartridge.

[0008] Preferably, a support plate perpendicular to the ink cartridge filling port is welded to the top of the back plate, a positioning sleeve is fixed at the center of the support plate, and an insertion tube is placed in the middle channel of the positioning sleeve.

[0009] Preferably, the diameters of both the front and rear ends of the insertion tube are larger than the inner diameter of the positioning sleeve.

[0010] Preferably, the filling mechanism includes a pump, the output end of which is connected to a water pipe and a plunger, and the input end of which is connected to a water pipe and a pumping pipe.

[0011] Preferably, the pump's input end is also connected to an air extraction pipe, and the air extraction pipe, water pipe two, and water extraction pipe are connected by an electromagnetic tee.

[0012] Preferably, the ink tank is connected to a filling tube on its side.

[0013] Preferably, the positioning structure includes two positioning plates symmetrically arranged along the centerline, and spring pieces are fixedly connected to the inner sides of both positioning plates.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0022] Example 1:

[0023] An ink-filling device for an inkjet printer, as described in reference Figure 1 - Figure 3 The base plate 1 and back plate 3 are L-shaped. The ink tank 4 is fixed on the back plate 3. The base plate 1 is provided with a positioning structure to fix the position of the ink tank.

[0024] The top of the back plate 3 is movably provided with a tube 6, which corresponds to the ink cartridge filling port and moves along its axis. A filling mechanism is provided between the tube 6 and the ink tank 4 to deliver ink from the ink tank 4 through the tube 6 into the ink cartridge.

[0025] The ink tank 4 also has its own ink extraction structure.

[0026] The ink cartridge is fixed in position by setting a positioning structure. The back plate 3 is provided with an axially movable tube 6. At the same time, the tube 6 works with the filling mechanism to draw ink from the ink tank 4 and enter the ink cartridge through the tube 6, thus completing the filling operation conveniently. Meanwhile, since both ends of the tube 6 are set with limiters, it can effectively avoid excessive insertion and damage to the ink cartridge.

[0027] A support plate 5 perpendicular to the ink cartridge filling port is welded to the top of the back plate 3. A positioning sleeve 51 is fixed at the center of the support plate 5. The insertion tube 6 is placed in the middle channel of the positioning sleeve 51. The purpose of the support plate 5 being perpendicular to the ink cartridge filling port is to ensure that the insertion tube 6 can smoothly enter the ink cartridge filling port and ensure its accurate guidance.

[0028] The diameters of both the front and rear ends of the insertion tube 6 are larger than the inner diameter of the positioning sleeve 51. The front end of the insertion tube 6 has a flat structure, and the purpose of its diameter being larger than the inner diameter of the positioning sleeve 51 is to limit it during insertion and withdrawal, so as to prevent it from coming out of the positioning sleeve 51.

[0029] The filling mechanism includes a pump 7, the output end of which is connected to a water pipe 8 and a tube 6, and the input end of the pump 7 is connected to a water pipe 91 and a pumping pipe 93.

[0030] The input end of pump 7 is also connected to an air extraction pipe 92. Air extraction pipe 92, water pipe 91, and water extraction pipe 93 are connected via an electromagnetic tee 94. The electromagnetic tee 94 is used to select the mode. During ink extraction, water pipe 91 and water extraction pipe 93 are connected, allowing ink in ink tank 4 to be pumped through pump 7 to the insertion tube 6, thus refilling the ink cartridge. When filling ink tank 4, the connection between water pipe 91 and air extraction pipe 92 is switched, causing pump 7 to expel air from ink tank 4, creating negative pressure inside, which then fills ink tank 4 through the filling tube 10.

[0031] The ink tank 4 has a filling tube 10 connected to its side. The filling tube 10 is used to connect to a larger external ink supply structure for ink supply. The outer wall of the ink tank 4 is fixed with a buckle to engage the filling tube 10.

[0032] The positioning structure includes two positioning plates 2 symmetrically arranged along the center line, and spring pieces 21 are fixedly connected to the inner sides of the two positioning plates 2.

[0033] The backplate 3 is equipped with a control mechanism 12, which includes control of the electromagnetic tee 94 and control of the extraction volume.

[0034] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of an ink-filling device for an inkjet printer provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
