[0029] In the embodiment, in order to solve the problem of large space occupied by the rotary printer in the prior art, the utility model adopts an innovative design: the cavity 1100 in the rotor 110 of the ring motor 100 is used to hide the ink cartridge unit 200. In this way, the ink cartridge unit 200 no longer occupies the external space independently, but is ingeniously arranged in the cavity 1100 of the rotor 110. This design makes the ink cartridge unit 200 form an integral whole with the ring motor 100, so that the overall size of the rotary printer is almost equal to the size of the ring motor 100, thereby greatly reducing the overall height of the printer and reducing the space occupied by the printer. Therefore, compared with the mode that the motor output end is connected to the end portion of the ink cartridge unit 200 in the prior art, the rotary printer of the utility model is more compact and can meet the needs of people to carry the rotary printer when going out.

[0030] In the embodiment, the ring motor 100 can be the prior art; the stator 130 is the stationary part of the ring motor 100, which is usually composed of a core with a coil wound thereon, and when current passes through the coil of the stator 130, a rotating magnetic field is generated; the rotor 110 is the rotating part of the ring motor 100; by supplying power to the coil of the stator 130, a rotating magnetic field is generated, and the rotating magnetic field interacts with the rotor 110 to make the rotor 110 rotate.

[0031] According to one embodiment of the utility model, the ring motor 100 further comprises a shell 120 and a stator 130; the shell 120 is sleeved on the outer peripheral wall of the stator 130; and the rotor 110 is coaxially and rotatably arranged in the stator 130.

[0033] According to one embodiment of the utility model, the utility model further comprises a printing control unit 300, which is connected to the shell 120 and electrically connected to the stator 130.

[0034] In the embodiment, the printing control unit 300 can directly control the working state of the ring motor 100, thereby accurately controlling the rotation speed and position of the ink cartridge unit 200.

[0035] In the embodiment, the rotor 110 comprises a first end 111 and a second end 112 in the axial direction O thereof; and the printing control unit 300 is located at the first end 111.

[0036] According to one embodiment of the utility model, the printing control unit 300 comprises a control mechanism 310 and a connecting mechanism 320; the control mechanism 310 is located in the cavity 1100, and the control mechanism 310 is connected to the shell 120 through the connecting mechanism 320.

This design ensures that the end face of the print head 220's print head 221 and the end face of the second end 112 of the rotor 110 are on the same plane and completely hidden within the rotor 110, which helps to further reduce the overall size of the printer, making it more compact and occupying less space. Simultaneously, because the end face of the print head 221 is flush with the end face of the second end 112, both end faces will contact the printing medium during printing. This increases the number of contact points with the printing medium, thus improving the printing stability of the rotary printer during the printing process and ensuring print quality.
