[0035] Reference Figs. 1 to 4The application provides a mechanism for preventing ink droplet splashing, which comprises an ink receiving disc 1 and an ink receiving block structure 2. The ink receiving disc 1 is arranged in an ink receiving container, the inside of the ink receiving container is provided with an ink droplet chamber for receiving ink droplets sprayed by a nozzle, and the bottom of the ink receiving disc 1 is provided with a slot 11 in communication with the ink droplet chamber. The ink droplets collected by the ink receiving disc 1 can flow into the inside of the ink receiving container through the slot 11, so that the ink droplets are collected by the ink receiving container, and the working environment is prevented from being polluted by the ink droplets sprayed by the nozzle. The ink receiving block structure 2 is arranged on the ink receiving disc 1 and is internally provided with a first ink droplet channel 21 and a second ink droplet channel 22 in communication. The first opening at the top of the first ink droplet channel 21 is located below the nozzle which is moved to a preset position and is ready to spray ink, and the size of the first opening is larger than that of the bottom opening of the nozzle, so that the ink droplets sprayed by the nozzle can accurately fall into the inside of the first ink droplet channel 21. The second opening at the bottom of the second ink droplet channel 22 is in communication with the slot 11, and the two ends of the first ink droplet channel 21 extend vertically upwards and downwards. The second ink droplet channel 22 is arranged at a preset angle relative to the first ink droplet channel 21. The ink droplets sprayed by the nozzle flow through the first ink droplet channel 21, the second ink droplet channel 22 and the slot 11 in sequence, and are finally collected into the inside of the ink receiving container, so that the splashing of the sprayed ink droplets is reduced.

[0036] When the use state of the nozzle is detected, the nozzle is moved to a preset position and is ready to spray ink. The nozzle is located directly above the first opening of the first ink droplet channel 21. The sprayed ink droplets flow into the inside of the ink receiving container through the first opening, the ink droplet channel and the slot 11 in sequence, so that the collection of the sprayed ink droplets is completed, and the working environment is prevented from being polluted. At the same time, since the first ink droplet channel 21 is arranged along the vertical direction, the sprayed ink droplets can quickly flow through the first ink droplet channel 21 through the first opening, so that the accumulation of the ink droplets in the inside of the first ink droplet channel 21 is avoided. Moreover, the second ink droplet channel 22 is arranged at an angle relative to the first ink droplet channel 21, so that the flow direction of the ink droplets is controlled, and the splashing of the ink droplets is effectively avoided.

In theory, the ink receiving block structure 2 can be provided in one piece, but considering that the first ink droplet channel 21 and the second ink droplet channel 22 need to be respectively formed in the interior of the ink receiving block structure 2, and the second ink droplet channel 22 is provided in an inclined manner, the one-piece provision of the ink receiving block structure 2 increases the processing difficulty of the two channels. In fact, the ink receiving block structure 2 can be provided in a split manner, that is, the ink receiving block structure 2 comprises the first ink receiving block 3 and the second ink receiving block 4 arranged in abutment, a vertical through hole is directly formed in the interior of the first ink receiving block 3, thereby forming the first ink droplet channel 21, and a part of the second ink receiving block 4 extends into the interior of the first ink receiving block 3, thereby forming the second ink droplet channel 22 between the two, and a second opening of the second ink droplet channel 22 is processed on the bottom surface of the second ink receiving block 4, which can reduce the processing difficulty of the first ink droplet channel 21 and the second ink droplet channel 22.

[0038] In some embodiments, the first ink receiving block 3 comprises a first main body part 31, the interior of the first main body part 31 is provided with a third channel 311, the interior of the third channel 311 is provided with at least one first inclined surface 312 inclined at a preset angle, and the size of the third channel 311 is larger than that of the first ink droplet channel 21 and is in communication with the top and the bottom of the first ink droplet. The top surface of the second ink receiving block 4 is provided with a protruding part 41 extending into the interior of the third channel 311, the protruding part 41 is provided with a second inclined surface 411 matched with the third channel 311, the second inclined surface 411 is provided in an inclined manner at a preset angle, and the space between the protruding part 41 extending into the third channel 311 and the inner side wall of the third channel 311 forms a second ink droplet channel 22 with a small space, and the second ink droplet channel 22 is provided in an inclined manner through the first inclined surface 312 and the second inclined surface 411 with the same inclined direction, thereby realizing the drainage of the ink droplets and effectively avoiding the splashing of the ink droplets.

[0039] In some embodiments, the bottom surface of the first main body part 31 is provided in parallel with the top surface of the second ink receiving block 4, and the height of the protruding part 41 extending in the vertical direction is the same as the depth of the third channel 311, and the top surface of the protruding part 41 is provided with a plane parallel to the top surface of the third channel 311, thereby realizing the sealing connection between the top of the protruding part 41 and the top surface in the interior of the third channel 311, and avoiding the formation of a gap that can allow the ink droplets to flow in.

[0040] In some embodiments, the inner side surface of the third channel 311 facing away from the first inclined surface 312 is provided in the vertical direction, and the outer side surface of the protruding part 41 facing away from the second inclined surface 411 is provided in the vertical direction, thereby realizing the sealing connection between the outer side surface of the protruding part 41 and the inner side surface of the third channel 311, and avoiding the formation of a gap that can allow the ink droplets to flow in.

[0041] In some embodiments, the first ink receiving block 3 further comprises a boss portion 32 protruding from the top surface of the first main body portion 31 by a preset height, and the first ink droplet channel 21 is arranged in the boss portion 32, the boss portion 32 protrudes upward by a certain height, which can improve the clarity of the camera shooting ink droplets, thereby improving the accuracy of the ink droplet working state detection.

[0042] In some embodiments, the third opening of the slot 11 is larger than the second opening, and the ink droplets flow through the first ink droplet channel 21 and the second ink droplet channel 22 in sequence, and due to the fact that the third opening of the slot 11 is larger than the second opening, the ink droplets can quickly flow into the interior of the ink receiving container through the slot 11, thereby realizing the rapid collection of the ink droplets.

[0043] In some embodiments, a corrosion-resistant coating is arranged on the inner side wall of the first ink droplet channel 21, the inner side wall of the third channel 311 and the outer side wall of the protruding portion 41, which can improve the corrosion resistance of the interior of the ink receiving block structure 2 and increase the service life of the ink receiving block structure 2.
