Problems solved by technology

However, for nozzles with specific internal structures, this method may not be able to completely clean the nozzles
[0004] It can be seen from this that the cleaning liquid in the prior art adopts the same flow mode as the ink working state, which may cause solidified ink or impurities to block the nozzle during cleaning, so the problem of nozzle plugging cannot be completely solved, which is serious. Affect the cleaning effect, and even the solidified ink or impurities will block the nozzle during cleaning, which will make the problem of nozzle plugging worse

Embodiment Construction

[0014] The embodiment of the present invention provides a device and method for cleaning the nozzle. The negative pressure generating device makes the cleaning liquid reversely flow inside the nozzle, thereby preventing the solidified ink and other impurities from clogging the nozzle, and achieving the purpose of more thorough cleaning of the nozzle.

[0015] An embodiment of the present invention provides a device for cleaning the nozzle, including: a cleaning tank and a negative pressure device, the cleaning tank is equipped with cleaning liquid for submerging the nozzle of the nozzle, wherein,

[0016] The ink port of the nozzle is in communication with the negative pressure device, wherein, under the negative pressure of the negative pressure device, the cleaning liquid is sucked from the nozzle of the nozzle and flows out from the ink port to the negative pressure device.

[0017] Preferably, the negative pressure device includes a negative pressure generating device and a...

Abstract

The invention discloses a device and a method for cleaning a spray head. The device comprises a cleaning tank and a negative pressure device, wherein the cleaning tank is filled with a cleaning solution for soaking a nozzle of the spray head, and the ink port of the spray head is communicated with the negative pressure device; and under the negative pressure action of the negative pressure device, the cleaning solution is sucked from the nozzle of the spray head and flows to the negative pressure device from the ink port. By adopting the device in the embodiment, the cleaning solution reversely flows in the spray head by using negative pressure, so that solidified ink and other impurities can be prevented from blocking the spray head, and the purpose of cleaning the spray head more thoroughly is fulfilled.

Description

technical field [0001] The invention relates to the field of inkjet printing, in particular to a device and method for cleaning a nozzle. Background technique [0002] In the field of inkjet printing, the ink may solidify inside the nozzle, and other impurities may also enter the nozzle, making the nozzle unable to work normally and affecting the printing quality. In order to prevent this situation, the nozzle needs to be cleaned regularly. The general method is to let the specific cleaning liquid flow forward inside the print head, that is: the cleaning liquid flows in from the ink port of the print head and flows out from the nozzle of the print head, so that the cleaning liquid dissolves the solidified ink and takes away impurities. [0003] In the Chinese Patent Application No. 01127740.8 "Color Inkjet Printer Nozzle Automatic Cleaning Method and Device" and the European Patent No. EP 1013437A1 "Printhead flush and cleaning system and method", both propose a method and ...
