Abstract

The invention discloses a check valve, a continuous ink supply system and a printer. The check valve includes a connection pipe which is provided with a first communication port and a second communication port, a piston shaft arranged in the connection pipe and used for moving in the length direction of the connection pipe to close or open the first communication port, a trigger shaft arranged inthe connection pipe and used for moving in the length direction of the connection pipe to close or open the second communication port. When the check valve is in a locked state, the piston shaft movesalong the connection pipe to close the first communication port, the backflow of ink due to long-term standing of the printer is prevented and the problem of ink leakage during transportation is solved. When the check valve is used again, the piston shaft is moved again, the check valve can be unlocked, and ink is supplied through the check valve again.

Description

technical field [0001] The invention belongs to the field of inkjet printers, and in particular relates to a check valve, a continuous ink supply system and a printer. Background technique [0002] The statements in this section merely provide background technical information related to the disclosure of the present invention, and do not necessarily constitute prior art. [0003] The continuous ink supply printer has an external large-capacity ink storage tank that allows users to refill ink freely. The ink is continuously delivered to the inkjet head through the ink delivery tube for image printing such as text and image files. It can print continuously without Ink cartridges need to be replaced, which reduces cost per print. [0004] However, when the printer is not in use or is being transported, the pressure imbalance in the pipeline will easily cause ink backflow and ink leakage during transport. Contents of the invention [0005] In view of the above, it is necessa...
