[0002] The ink cartridges of today's handheld portable printers generally adopt a square design. The metal contacts of the flexible circuit board connected to the nozzle on the ink cartridge are all set on the side of the ink cartridge. In order to make the electrical connection between the ink cartridge and the printer more stable, the connection stress between the contacts and the probes is relatively large. When disassembling and installing the ink cartridge, the probe on the printer will successively pass over the metal contacts on the ink cartridge, which will cause wear on the probes and metal contacts. After long-term use, it will cause poor electrical connection between the ink cartridge and the printer. At the same time, in the field of rotary printers, in order to prevent the ink cartridge from shifting when rotating, the connection between the ink cartridge and the printer is tighter, which is very inconvenient to disassemble.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Embodiment 1: A special ink cartridge for a rotary printer

[0023] like Figure 1-Figure 4 As shown, the present embodiment provides a special ink cartridge for a rotary printer, comprising an ink cartridge body, a flexible circuit board 300, a nozzle 400, a central axis 100 and an elastic card 500, wherein the first end 320 of the flexible circuit board is electrically connected to the nozzle 400 at the bottom of the ink cartridge body, and the elastic card 500 of the present embodiment comprises a rebound rod and a clamping portion, wherein the rebound rod can rebound to an initial position after being pressed, and the clamping portion is used to clamp on the rotary printer, and the ink cartridge body of the present invention comprises a first shell 210 and a second shell 220, wherein the first shell 210 and the second shell 220 are connected to each other. The ink cartridge 10 includes a front shell 211 and an outer wall 212, and the second shell 220 includes an ink tank wall 221 and a bottom shell 222. The front shell 211 is the top of the ink cartridge body. The second end 310 of the flexible circuit board is provided with a metal contact 311 that abuts against the probe of the printer. The second end 310 of the flexible circuit board is provided on the top surface of the front shell 211, that is, the upper surface. The bottom shell 222 is the bottom of the ink cartridge body. When the ink cartridge is assembled, the lower end of the outer wall 212 is fixedly connected to the bottom shell 222, and the fixed connection method can be adhesive, bonding, etc. When the ink cartridge is assembled, the ink tank wall 221 is wrapped in the outer wall 212, and the ink tank wall 221 is fixedly connected to the bottom shell 222. The ink tank wall 221, the bottom shell 222 and the front shell 211 form an ink cavity 700 for storing ink. In the ink cavity 700, an ink outlet for ink to flow out is provided on the bottom shell 222, and the ink outlet is connected to the nozzle 400.

[0024] Specifically, the front shell 211 and the outer side wall 212 of this embodiment are integrally formed to form the first shell 210, and the bottom shell 222 and the ink tank wall 221 are integrally formed to form the second shell 220. The first shell 210 and the second shell 220 are both integrally formed to minimize the number of structural parts of the main body of the ink cartridge, making it more convenient to assemble the ink cartridge.

[0025] In this embodiment, two elastic cards 500 are provided, and the two elastic cards 500 are symmetrically arranged on the outer side wall 212 of the first housing 210. The two symmetrically arranged elastic cards 500 can conveniently and quickly remove the ink cartridge by pinching the two elastic cards 500 with two fingers of one hand when removing and installing the ink cartridge.

[0026] In this embodiment, the nozzle holes are arranged in a single row, the center axis of the central axis 100 is perpendicular to the line of the nozzle holes, and the center axis of the central axis 100 coincides with the center axis of the ink cartridge. The above structure enables the nozzle 400 to fully cover the area of ​​the rotating printer during rotation.

[0027] like Figure 4 and Figure 5 As shown, the rotary printer ink cartridge of this embodiment is further provided with a pull ring 600, which is provided at the bottom of the bottom shell 222. One end of the pull ring 600 of this embodiment can rotate around the other end. Figure 4 is a three-dimensional diagram of the pull ring 600 in a buckled state. Figure 5 The drawing is a three-dimensional diagram of the pull ring 600 in a pulled-up state. The pull ring 600 can make the ink cartridge more convenient to disassemble and assemble.

[0028] like Figure 3 As shown, in this embodiment, the cross-section of the ink tank wall 221 is a square, and in other embodiments, it can be deformed in other forms. Since the ink cartridge of the rotating handheld printer is generally filled with an ink-absorbing sponge 701, and then the ink is poured into the sponge 701, by setting the cross-section of the ink tank wall 221 to a square, the ink cartridge is not easily misaligned when rotating, and the ink can be prevented from moving to the edge of the ink tank wall 221 due to the influence of centrifugal force when the ink cartridge rotates, so that the ink can be more evenly distributed in the ink cavity 700.

[0029] Embodiment 2: A rotary printer

[0030] This embodiment provides a rotary printer. The rotary printer-specific ink cartridge in Embodiment 1 is arranged at the bottom of the rotary printer. The rotary printer-specific ink cartridge is connected to the bottom of the rotary printer via an elastic card.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
