This printer is usually equipped with three or four printing heads, each responsible for ejecting ink of one color, including yellow, magenta, cyan, and black, and the combination of these four colors can produce a rich color effect. In addition, there is a design that uses a single nozzle, but this nozzle can eject ink of the four colors separately, and by precisely controlling the operation of the nozzle, four-color printing is achieved.

The protective component can then be used to protect the nozzle to prevent it from colliding with other objects during printing. Finally, the cleaning component can be used to clean the residues after printing.

[0032] like Figure 6 As shown, the protective component includes a connecting plate 6 arranged on the front wall of the printing carriage 3, a mounting frame 7 is provided at the bottom of the connecting plate 6, a rotating shaft 12 is provided inside the mounting frame 7, a driven wheel 13 is provided outside the rotating shaft 12, the bottom of the rotating shaft 12 extends to the outside of the mounting frame 7 and is provided with an electric push rod 8, and a rotating block 9 is provided at the telescopic end of the electric push rod 8, one end of the rotating block 9 is an anti-collision end 11 for preventing the nozzle from colliding, and the other end of the rotating block 9 is a protective end 10 for protecting the nozzle.

[0033] The telescopic end of the electric push rod 8 is moved downward, thereby driving the rotating block 9 to move downward, so that the protection end 10 of the rotating block 9 is away from the nozzle, the anti-collision end 11 of the rotating block 9 can prevent the nozzle from being easily collided during printing, and the protection end 10 can better protect the nozzle during non-working.

[0034] As shown in Figure 5 , the inside of the mounting frame 7 is provided with a motor 15, and the output shaft of the motor 15 is provided with a driving wheel 14 which is engaged with the driven wheel 13.

[0035] When the motor 15 needs to work to drive the driving wheel 14 to rotate, the driven wheel 13 which is engaged with the driving wheel 14 will also rotate, and after the driven wheel 13 rotates one hundred and eighty degrees, the anti-collision end 11 of the rotating block 9 will be located below the nozzle.
