[0032] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] Existing inkjet printers use external laser pointers, but these external laser pointers are prone to falling off and require repeated calibration. The detachable laser module also poses a risk of mechanical structural loosening, and the matching accuracy between the laser path and the printing trajectory is insufficient.
[0035] The following is a portable inkjet printer with an integrated laser positioning system provided by this utility model, which can solve the above-mentioned technical problems.
[0036] In the diagram, units with similar structures are represented by the same labels.
[0037] See Figure 1 , Figure 2 and Figure 3This utility model provides a portable inkjet printer with an integrated laser positioning system, including a housing 1, an inkjet module 2, and a laser emitter 3. Inkjet nozzles 161 and laser emission nozzles 131 are respectively provided on adjacent sides of the housing 1. The inkjet module 2 is installed inside the housing 1, with its ejection end protruding along the inkjet nozzle 161. The laser emitter 3 is installed inside the housing 1, with its emission end facing the laser emission nozzle 131. The optical axis of the laser emitter 3 is coplanar with the ejection axis of the inkjet module 2, and the angle between the optical axis of the laser emitter 3 and the ejection axis of the inkjet module 2 is an acute angle.
[0038] The optical axis of the laser emitter 3 is coplanar with the jetting axis of the inkjet module 2 (ensuring the laser path matches the printing trajectory). The angle between the optical axis of the laser emitter 3 and the jetting axis of the inkjet module 2 is an acute angle (when coding is required, the jetting axis of the inkjet module 2 is perpendicular to the plane to be coded, and the angle between the optical axis of the laser emitter 3 and the jetting axis of the inkjet module 2 is an acute angle, so that the laser emitted by the laser emitter 3 can illuminate the plane to be coded). The laser emitter 3 emits a laser to plan the route and position the marker, which can guide the inkjet module 2 to print. The laser path and printing trajectory match with high accuracy. The laser emitter 3 is installed inside the coding machine, and the laser emitter 3 is not easy to fall off. The integrated structure can reduce assembly processes, and the laser emitter 3 does not need to be repeatedly calibrated.
[0039] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The housing 1 contains a mounting plate 11, on which a first clamping plate 111 and a second clamping plate 112 protrude and clamp the laser emitter 3. The first clamping plate 111 and the second clamping plate 112 clamp the laser emitter 3, making it easy to assemble and disassemble the laser emitter 3.
[0040] In some embodiments, see Figure 3 , Figure 4 and Figure 5 A first locking block 1111 is provided on the side of the first clamping plate 111 near the second clamping plate 112, and a second locking block is provided on the side of the second clamping plate 112 near the first clamping plate 111. The first locking block 1111 and the second locking block are used to prevent the laser emitter 3 from dislodging between the first clamping plate 111 and the second clamping plate 112. The first locking block 1111 and the second locking block restrict the laser emitter 3 from dislodging, ensuring the installation stability of the laser emitter 3 and improving its shock resistance performance by 300% (according to the vibration test standard GB / T 2423.10).
[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3The housing 1 includes a first outer shell 12, a second outer shell 13, and a mounting bracket 14. A mounting plate 11 is connected to one side of the mounting bracket 14, and the first outer shell 12 and the second outer shell 13 are detachably connected. The mounting bracket 14 and the mounting plate 11 are located between the first outer shell 12 and the second outer shell 13. The inkjet module 2 is mounted between the mounting bracket 14 and the mounting plate 11, and the laser emission port 131 is located on the second outer shell 13. The housing 1 has a compact overall structure and is easy to assemble and disassemble. An ink cartridge compartment cover 18 is provided on the housing 1, and the ink cartridge compartment cover 18 is correspondingly arranged with the inkjet module 2. A main control board 19 is also provided inside the housing 1, which controls the operation of the inkjet module 2 and the laser emitter 3.
[0042] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The housing 1 also includes a maintenance cover 15, which is detachably connected to the mounting bracket 14. A mounting plate 11 is located between the mounting bracket 14 and the maintenance cover 15, and the maintenance cover 15 is located between the mounting plate 11 and the second outer shell 13. The maintenance cover 15 is provided with a clearance groove 151 for the first clamping plate 111 and the second clamping plate 112 to extend into. When the laser emitter 3 needs to be replaced, only the second outer shell 13 needs to be removed, exposing the first clamping plate 111 and the second clamping plate 112, without requiring complete disassembly.
[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The housing 1 also includes a front sealing plate 16, which connects the first outer shell 12 and the second outer shell 13. The inkjet nozzle 161 is located on the front sealing plate 16. The overall structure of the housing 1 is compact and easy to assemble and disassemble. A roller 162 is rotatably connected to the front sealing plate 16. The roller 162 facilitates the movement of the inkjet printer on the surface to be inkjetized.
[0044] In some embodiments, see Figure 1 , Figure 2 and Figure 3 A transparent light-transmitting plate 1311 is provided at the laser emission port 131. The light-transmitting plate 1311 can also be dustproof and sealed, and the material of the light-transmitting plate 1311 is optical grade polycarbonate.
[0045] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The laser emission port 131 is an elongated slot, and the length direction of the laser emission port 131 is the direction of the jetting axis of the inkjet module 2. The laser emitter 3 emits a laser, which passes through the laser emission port 131 and shines on the surface to be printed. The elongated slot shape of the laser emission port 131 can ensure that the light emitted by the laser emitter 3 is not easily blocked by the second outer shell 13.
[0046] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The housing 1 includes a handle 17. When the handle 17 is facing downwards and the inkjet nozzle 161 is facing forward, the laser emission port 131 is located on the right side of the housing 1. During printing, the handle 17 is held, and the roller 162 on the front cover plate 16 abuts against the printing surface. Printing generally proceeds from left to right. The laser emission port 131 is located on the right side, allowing the laser beam to be pre-planned for positioning during printing.
[0047] In some embodiments, see Figure 1 and Figure 2 The angle between the optical axis of the laser emitter 3 and the jetting axis of the inkjet module 2 ranges from 11.5° to 12.5°. The fixed angle design ensures that the deviation of the laser reference line (the light emitted by the laser emitter 3) within a 3-meter printing distance is less than 0.5mm.
[0048] The working principle of this utility model is as follows: the hand handle 17 is held, the roller 162 on the front cover plate 16 abuts against the inkjet printing plane, the laser emitter 3 emits a laser, which passes through the laser emission port 131 and shines on the inkjet printing plane, which can be used to assist in positioning and determine the inkjet printing position. The inkjet module 2 prints the ink and moves the inkjet printer from left to right to complete the inkjet printing operation.
[0049] This completes the working process of a portable inkjet printer with an integrated laser positioning system.
[0050] In summary, although the present invention has been disclosed above, it is not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
