[0018] Reference Figure 1-3 The utility model provides an inkjet droplet generator: it includes a generator assembly 1, the outer side of the generator assembly 1 is provided with a limiting ring 2; the right end of the generator assembly 1 is provided with a connecting tube 3, and the right end of the connecting tube 3 is provided with a nozzle 4 and a screen 5; the outer side of the generator assembly 1 and the outer side of the connecting tube 3 are provided with a fixing ring 6; the inner side of the generator assembly 1 is provided with an inner cavity 7; the inner side of the generator assembly 1 and the inner side of the connecting tube 3 are provided with a reset assembly 8; the adjacent ends of the two reset assemblies 8 are each provided with a connecting assembly 9. When using the device, the nozzle 4 is installed into the generator assembly 1 through the reset assembly 8, the connecting assembly 9 and the fixing ring 6, and the inner wall of the generator assembly 1 is blocked by the components in the reset assembly 8. Therefore, the ink is blocked inside during the disassembly process, avoiding the ink dripping and sticking to the hands, which is inconvenient for people to disassemble and subsequently install.

[0019] It should be noted that before disassembly and installation, the generator assembly 1 needs to be completely disassembled from the printer or inkjet printer for inspection and maintenance.

[0020] As a further implementation scheme of the above technical solution: Figure 2-3 As shown, the reset assembly 8 includes a spring 801; the end of the spring 801 close to the connecting assembly 9 is provided with a ball 802; the end of the connecting pipe 3 close to the connecting assembly 9 and the end of the generator assembly 1 close to the connecting assembly 9 are provided with a fixed cavity 803, the ball 802 is located in the fixed cavity 803 provided in the connecting pipe 3 and the fixed cavity 803 provided in the generator assembly 1, and the ball 802 is slidably connected to the connecting pipe 3 and the generator assembly 1. During the installation or removal process, the connecting pipe with the nozzle 4 is The connecting pipe 3 is inserted into the fixing ring 6 from right to left, and the fixing ring 6 and the connecting pipe 3 are threadedly connected, so the fixing ring 6 can be rotated during insertion. The fixing ring 6 is limited by the limiting ring 2, so that the connecting pipe 3 moves to the left until the connecting component 9 is inserted into the generator component 1. At this time, the connecting component 9 contacts the ball 802 at the left end and squeezes the spring 801 at this position to the left, so that the ball 802 in the reset component 8 at the left end is out of contact with the generator component 1, so that a gap appears in the fixed cavity 803.

[0021] As a further implementation scheme of the above technical solution: the connecting component 9 includes a fixed tube 901, and a sealing ring 904 is fixedly connected to the middle part of the outer side of the fixed tube 901. The left and right ends of the fixed tube 901 are fixedly connected to the contact tube 902, and the front and rear ends of the contact tube 902 are provided with grooves 903. The end of the contact tube 902 away from the fixed tube 901 contacts the ball 802 in the reset component 8, and the contact tube 902 at the right end is fixedly connected to the ball 802 at the right end, and the contact tube 902 at the left end is slidably connected to the ball 802 at the left end. The right end of the sealing ring 904 is fixedly connected to the connecting tube 3, and the left end of the sealing ring 904 is slidably connected to the right end of the generating component. The sealing ring 904 is composed of a hard silicone block. When the connecting component 9 is inserted into the generator component 1, as the fixing ring 6 rotates, the left end of the connecting tube 3 contacts the right end of the generator component 1. At this time, the sealing ring 904 in the connecting component 9 is in close contact with the middle of the right end of the generator component 1. At the same time, the contact tube 902 at the left end of the fixed tube 901 contacts and squeezes the ball 802 in the left end reset component 8, and the fixed tube 901, the right end contact tube 902 and the sealing ring 904 of the connecting component 9 are fixed to the connecting tube 3 and the right end reset component 8. Therefore, when the connecting block tube is pushed to the right by the fixing ring 6 to be disassembled, the reset component 8 in the generator component 1, under the action of the spring 801, causes the ball 802 to block the opening position of the generator component 1 to prevent excess ink inside from flowing out through this position.

[0022] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
