Abstract

The invention relates a jet printing unit which at least comprises an orifice plate, a plate body, an oscillating plate and runner exhaust elements, wherein the plate body is arranged to be adjacent to the orifice plate and is provided with a runner, the oscillating plate is arranged on the plate body and is provided with an exhaust hole, partial runner exhaust elements are arranged between the oscillating plate and the plate body, and each runner exhaust element at least comprises a film arranged and covers on an exhaust hole, an exhaust communicating groove communicated with the exhaust hole, and a microrunner arranged between the runner and the exhaust communicating groove and communicated with the runner and the exhaust communicating groove to ensure that gas flows to the exhaust communicating groove and is exhausted through the exhaust hole through the film. By means of the communication of the runner, the microrunners, the exhaust communicating grooves and the films, the gas in the runners is exhausted, and the effects of maintaining jet printing quality and reducing money and time waste are achieved.

Description

Technical field [0001] The present invention relates to a jet printing unit, in particular to a jet printing unit that can eliminate air bubbles in a flow channel and maintain the quality of jet printing. Background technique [0002] In recent years, with the vigorous development of personal computers and industrial technology, the integration of technology and daily life has become closer. Printing equipment has become an indispensable product for personal computer peripherals in enterprises or homes. Among them, inkjet printers are used. It has the advantages of low price, simple replacement of consumables and easy access, so it is widely used by consumers. [0003] Known inkjet printers mainly use inkjet heads to perform the printing action, and the inkjet printing unit on the inkjet head is arranged on the ink cartridge and is made up of multiple layers of objects, including nozzles with nozzles, vibration Plates and multi-layer plates, etc., to form the main flow channel. T...
