Printing head structure

Abstract

The invention discloses a printing head structure which is used for being communicated with an ink box, the ink box comprises an ink outlet pipe port, the printing head structure comprises a printing head body, an upper ink channel and a lower ink channel are arranged on the printing head body, the upper ink channel is butted with the ink outlet pipe port, the lower ink channel is connected with a nozzle wafer, the upper ink channel is communicated with the lower ink channel, clapboards are arranged in the upper ink channel and divide the upper ink channel into a plurality of ink channels, and each ink channel is communicated with the lower ink channel. According to the printing head structure, when ink entering into the upper ink channel enters into the lower ink channel through the plurality of ink channels divided by the clapboards, bubbles in the ink can not accumulate due to the obstructing of the clapboards and are prevented from entering into the lower ink channel, blocking of the ink channels caused by the accumulation of the bubbles is relieved, and printing quality of an ink-jet printer is well improved.

Description

technical field [0001] The invention relates to a nozzle structure, in particular to a nozzle structure that can reduce the accumulation of air bubbles in ink channels. Background technique [0002] As a common office equipment, inkjet equipment (such as inkjet printer) provides great convenience for modern office. The general working principle of inkjet equipment is: the main board of the inkjet equipment transmits the printing information to the nozzle wafer located on the nozzle body. , the ink in the ink cartridge flows through the upper ink channel of the nozzle body and then enters the lower ink channel, and the ink in the lower ink channel is formed by the nozzle to form ink droplets and drop on the printing medium to form printing ink marks. During the working process of the inkjet printer, air may enter the ink and enter the upper and lower ink channels of the nozzle body together with the ink. The air forms bubbles in the upper and lower ink channels. When the bubb...

AI Technical Summary

Problems solved by technology

During the working process of the inkjet printer, air may escape into the ink, and enter the upper ink channel and the lower ink channel of the nozzle body together with the ink. The air forms air bubbles in the upper and lower ink channels. When the bubbles continue to accumulate When it is large enough, it will cause the phenomenon of empty ink, so that the nozzle cannot output ink according to the printing information and form a clogging phenomenon, especially as the ink cartridge is a printing consumable, when replacing the ink cartridge, it is easy to introduce air into the ink to form Air bubbles, the continuous accumulation of air bubbles in the upper and lower ink channels, may affect the printing quality of inkjet printers
