Embodiment 1

[0022] Such as figure 1 As shown, the ink supply needle includes a needle head 1, a needle seat 2, a one-way valve 3, a detection chamber 4, and an ink outlet 5. The needle head 1 is fixedly connected to the needle seat 2, and the one-way valve 3 is fixed on the needle seat 2. The valve 3 is a duckbill type, the ink flows from the top of the needle 1 to the bottom of the needle 1, and then flows to the one-way valve 3, the one-way valve is opened, the ink flows into the detection chamber 4, and then enters the ink delivery pipe from the ink outlet 5. In the case of backflow, the ink flows into the detection chamber 4 from the ink outlet 5, and since the one-way valve 3 prevents the flow of ink, the ink will not flow to the needle through the one-way valve.

Embodiment 2

[0024] Such as figure 2 , 3 As shown in , 4, the ink supply needle includes a needle head 1, a needle seat 2, a one-way valve 3, a detection chamber 4, an ink outlet 5, and a return chamber 6. The needle head 1 has a fastener one 11, a fastener two 12, and a needle Hole 13, there is a gap between fastener one 11 and fastener two 12, so that the fixed connection between needle head 1 and needle seat 2 is more firm, needle seat 2 has thread 21, positioning gap 22, thread connection is tighter, positioning gap When the thread is fixed, the ink supply needle will not rotate, which will not affect the fixation of the ink supply needle; the one-way valve 3 is fixed on the needle seat 2, and the one-way valve 3 is duckbill type; the one-way valve 3 and the detection chamber 4 have a The reflow chamber 6, the reflow chamber has an opening 61, so that the ink enters the detection chamber through the opening 61, and the ink flow is more stable. The detection chamber is flat, which ma...

Abstract

The invention relates to an ink supplying needle which is used for an ink continuous supply system of an ink-jet printer. The ink supplying needle comprises a needle head, a needle seat, a check valve, a detection room and an ink outlet. The ink supplying needle is used to solve the technical problem that an existing ink supplying needle used for an ink-jet printer leaks ink.

Description

technical field [0001] The invention relates to an ink supply needle, in particular to an ink supply needle used in an ink supply system of an inkjet printer. Background technique [0002] The ink supply of ink-jet printer is usually carried out with the ink cartridge of certain volume, and ink cartridge is installed in the printing head that has cartridge storehouse detachably, must replace new so that continue to work when the ink in the ink cartridge runs out. Since the amount of ink that can be printed in one ink cartridge is limited, such as about 500 sheets, this brings inconvenience to printing work, especially large-volume printing work. [0003] After the ink in the built-in ink cartridge is exhausted, the built-in ink cartridge can only be refilled with ink through the ink replenishment bottle or the continuous ink supply ink cartridge can be supplemented with ink, so that the built-in ink cartridge can obtain secondary use value or make the continuous ink supply i...
