Ink jet device convenient to clean

Abstract

The invention relates to an ink jet device convenient to clean, and effectively solves the problem that a conventional ink jet device is time-consuming and labor-consuming when being cleaned. The ink jet device comprises a spray head and an ink cartridge, wherein the ink cartridge communicates with the spray head through a connecting device; the connecting device comprises an upper connecting pipe, a spheroidal hood and a lower connecting pipe, wherein one end of the upper connecting pipe communicates with the ink cartridge through a control valve, and the other end of the upper connecting pipe communicates with the upper end of the spheroidal hood; the lower end of the spheroidal hood communicates with one end of the lower connecting pipe, and the other end of the lower connecting pipe communicates with the spray head; and an opening is formed in the upper part of the spheroidal hood. The ink jet device disclosed by the invention is simple in structure and convenient to use; the spheroidal hood is arranged on the pipeline through which the ink cartridge and the spray head communicate, so that on one hand, under the premise that the spray head is not disassembled and the volume is not increased as far as possible, the purpose of injecting a cleaning agent to the spray head is realized; and on the other hand, the spheroidal hood can also achieve the effect of controlling flow.

Description

technical field [0001] The invention relates to an inkjet device, in particular to an inkjet device which is easy to clean. Background technique [0002] Along with the progress day by day of science and technology, the kind of ink-jet printing equipment is more and more, and the range of application is also more and more extensive, and its ink-jet device comprises ink box and the print head that communicates with ink box, yet, in the existing ink-jet device There is no device for cleaning. When encountering the problem of clogged nozzle holes caused by dry ink, it is often necessary to disassemble the nozzle for cleaning, which not only takes time and effort, but also delays the printing work. Even if individual manufacturers have adopted a negative pressure ink suction device to avoid the trouble of disassembling the nozzle, but because there is no corresponding cleaning supporting device, the cleaning effect is not very satisfactory, which is very inconvenient.
