[0024] The utility model embodiment provides a nozzle cleaning mechanism of an inkjet printer.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a nozzle structure, the nozzle structure includes a mounting plate 2 and a nozzle 7, the mounting plate 2 is fixedly connected to a side away from the nozzle 7 with an electric telescopic rod 14, the top of the electric telescopic rod 14 is fixedly connected to a fixed bent plate 15, one side of the fixed bent plate 15 is fixedly connected to a device support frame 16, a water pump 17, a sealing box 18 and an air pump 19 are fixedly installed on the equipment support frame 16, and an air storage airbag 23 is provided at the air outlet end of the air pump 19.

[0026] When the utility model is in use: two guide rods 3 are fixedly connected to one side of the baffle plate 1 in the nozzle structure, one end of the guide rod 3 passes through the mounting plate 2, and a buffer 4 is threadedly installed on one side of the mounting plate 2, and one end of the buffer 4 is against the baffle plate 1. The nozzle structure with structures such as the baffle plate 1, mounting plate 2, guide rod 3, buffer 4, sliding frame 6, and nozzle 7 is a public technology and will not be described here. For details, please refer to the utility model of patent application number: 202122747824.3, which discloses a nozzle for an inkjet printer.

[0027] A transmission frame 9 is fixedly sleeved on the outer side of one of the guide rods 3, and a sliding frame 6 slidably connected to the transmission frame 9 is fixedly connected to the mounting plate 2. When the baffle 1 drives the mounting plate 2 to move, the mounting plate 2 drives the nozzle 7 fixedly connected to one end of the transmission frame 9 through the transmission frame 9 to move synchronously, thereby ensuring the relative position between the nozzle 7 and the baffle 1.

[0028] When the nozzle 7 needs to be cleaned,

[0029] The electric telescopic rod 14 and the air pump 19 fixedly connected to the control mounting plate 2 are working. The electric telescopic rod 14 drives the fixedly connected fixed curved plate 15 to move downward. The downwardly moved fixed curved plate 15 drives the equipment support frame 16 fixedly connected on one side to move downward. The downwardly moved equipment support frame 16 drives the water pump 17 fixed at the bottom to move downward. During the downward movement of the water pump 17, the air pump 19 works to output airflow through the exhaust elbow 20 fixedly connected to the air outlet end, and the bottom of the fixed plate 21 fixedly sleeved on the outside of the exhaust elbow 20 is fixedly connected to an air storage airbag 23. Therefore, the air pump 19 inflates the air into the air storage airbag 23 sealed by the fixed plate 21 through the exhaust elbow 20, so that the air storage airbag 23 expands into a triangle with a curved surface on one side, such as Figure 4 As shown, the curved surface of the air storage bag 23 pushes the baffle 1 on one side to move toward the mounting plate 2, and the nozzle 7 and the baffle 1 move to the cleaning position. When the mounting plate 2 and the equipment are fixed and cannot move, the baffle 1 will drive the nozzle 7 to move synchronously.

[0030] When the baffle 1 moves to the limit, the electric telescopic rod 14 drives the sealing box 18 to move downward and insert it between the baffle 1 and the nozzle 7. The drainage pipe 13 fixedly installed at the water outlet end of the water pump 17 moves downward and is sleeved on the outside of the guide pipe 11. The electromagnetic valve 10 fixedly connected to the top of the ink supply pipe 8 is fixedly connected to the guide pipe 11. Therefore, at this time, the water pump 17 is connected to the inside of the ink supply pipe 8 through the drainage pipe 13, the guide pipe 11 and the electromagnetic valve 10 that is open for work. The hose 25 fixedly connected at one end of the water pump 17 is used for pumping water. After being pumped, the water is discharged into the ink supply tube 8 through the drainage pipe 13, the guide tube 11 and the solenoid valve 10. The water flows into the nozzle 7 through the ink supply tube 8 to flush the inside of the nozzle 7. The sewage discharged from the nozzle 7 enters the sealing box 18. The sewage is finally discharged through the hose 25 fixedly connected to one side of the sealing box 18, and the flushing work of the nozzle 7 can be completed. It only needs to control the operation of the electric telescopic rod 14, the water pump 17 and the air pump 19 to automatically clean the nozzle 7, ensuring that the flushing and cleaning of the nozzle 7 is stable and fast.

[0031] The part of the exhaust elbow 20 that is fixed vertically downward to the fixing plate 21 is a telescopic tube, and the force required to shrink the telescopic tube part of the exhaust elbow 20 is much greater than the force required to shrink the buffer 4, so the buffer 4 shrinks in the early stage of the movement of the baffle 1 pushed by the air storage airbag 23. When the bottom of the air storage airbag 23 contacts the transportation equipment and is limited, the buffer 4 shrinks to the limit, the movement of the baffle 1 is limited, and the exhaust elbow 20 fixed by the air storage airbag 23 through the fixing plate 21 shrinks.

[0032] An exhaust valve 22 is fixedly connected to the top of the fixed plate 21. When the nozzle 7 is cleaned, the exhaust valve 22 and the electric telescopic rod 14 are controlled to work. The electric telescopic rod 14 pushes the equipment support frame 16, the water pump 17, the air pump 19, the sealing box 18 and other parts to reset. The internal gas of the air storage bag 23 is discharged through the exhaust valve 22, so that the air storage bag 23 shrinks to the bottom of the fixed plate 21.

[0033] A sealing sleeve 12 is fixedly connected inside the drainage pipe 13 , and the deformed sealing sleeve 12 increases the sealing performance between the drainage pipe 13 and the guide pipe 11 .

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
