A printing head, umbilical cord catheter and printing assembly

Abstract

The present application relates to a printing head, an umbilical catheter and a printing assembly. The printing head is used for detachably plugging in a matching umbilical catheter. A first electrical end for electrical connection with the umbilical conduit and a first fluid end for fluid connection with the umbilical conduit; the first fluid end includes a first ink discharge portion, a first ink supply portion, and a first cleaning portion and the first recovery part; the first ink discharge part, the first ink supply part and the first cleaning part are all connected to the spray chamber of the first body, and the first recovery part is connected to the ink recovery pipe of the first body. In this application, the first electrical end and the first fluid end are integrated on the same end face, and when plugging in with a suitable umbilical catheter, the electrical connection and the fluid connection can be realized at the same time, avoiding the occurrence that the operator only completes the Powering on the printer without making an electrical connection without making a fluid connection caused problems with ejecting ink from the ink manifold.

Description

technical field [0001] The present application relates to the technical field of inkjet printing, in particular to a printing head, an umbilical catheter and a printing assembly. Background technique [0002] Inkjet printers form images by pushing ink droplets against a substrate. Whereas printers form images by producing droplets from multiple nozzles when needed, continuous inkjet printers use electrostatics to deflect charged droplets from a single nozzle to multiple locations for image forming purposes. [0003] Continuous inkjet printers typically consist of an ink supply system, control electronics, and a printhead that is fluidly connected to the ink supply system via multiple tubes and electrically connected to the control electronics by wires. [0004] Clearly, the printhead implements a number of control signals to deliver ink and solvent to and from the printhead. [0005] When users want to replace the printhead with different size nozzles to print smaller or l...
