[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] The following is for reference. Figures 1-4 The implementation of the nozzle shell anti-collision plate structure proposed in the embodiments of this utility model will be described in detail.

[0029] The nozzle housing anti-collision plate structure according to an embodiment of the present utility model includes: a box body 1 and an anti-collision plate 2.

[0030] Specifically, the cartridge 1 has an installation space 11 and a first opening 12 communicating with the installation space 11. The installation space 11 is suitable for installing ink cartridges. The first opening 12 is located on the front end face of the cartridge 1 to expose the print head of the ink cartridge. The two outer side walls of the cartridge 1 are recessed at the junction with the front end face of the cartridge 1 so that the front end face of the cartridge 1 and the recess 13 together form a protective area. The anti-collision plate 2 is installed in the protective area so that the front end 21 and the two side wings 22 of the anti-collision plate 2 are correspondingly attached to the front end face of the cartridge 1 and the recess 13 of the cartridge 1. The front end 21 of the anti-collision plate 2 has a second opening 24 communicating with the first opening 12. There is a guide section 23 between the side wings 22 and the front end 21 of the anti-collision plate 2.

[0031] In other words, the installation space 11 of the cartridge body 1 is used to install the ink cartridge, and the anti-collision plate 2 is suitable for installation on the cartridge body 1. The second opening 24 of the anti-collision plate 2 communicates with the first opening 12 of the cartridge body 1, which facilitates the ink cartridge's print head to print on the object. The concave setting of the cartridge body 1 forms a clearance space, so that when the anti-collision plate 2 is installed on the cartridge body 1, the two side wings 22 of the anti-collision plate 2 can fit against the concave part 13 of the cartridge body 1. A guide section 23 is provided between the side wings 22 and the front end 21 of the anti-collision plate 2, which can smoothly transition the object to the print nozzle. This not only reduces the space occupied by the anti-collision plate 2, which is conducive to printing the object in a narrow space, but also retains the guiding function of the anti-collision plate 2. The anti-collision plate 2 can be made of metal or plastic. The anti-collision plate 2 and the box body 1 can be installed by screw locking or snap-fit. The guide section 23 can be composed of a straight section or an arc section. The thickness of the two side wings 22 of the anti-collision plate 2 can be consistent with the concave depth of the box body 1, so that the outer wall of the anti-collision plate 2 and the outer wall of the box body 1 are coplanar after the anti-collision plate 2 is installed.

[0032] Therefore, a protective area is formed by the recessed setting at the intersection of the front end face of the box body 1 and the two side walls of the box body 1, so that the front end 21 and the two side wings 22 of the anti-collision plate 2 can be installed in close contact with the protective area of ​​the box body 1. The guide section 23 between the front end 21 and the two side wings 22 of the anti-collision plate 2 allows the printing object to be close to and smoothly pass through the printing nozzle. This not only greatly reduces the space occupied by the anti-collision plate 2, but also improves the overall integrity and is conducive to use in narrow spaces.

[0033] Optionally, a positioning structure with a concave-convex fit is provided between the box body 1 and the anti-collision plate 2.
