Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment, and in particular to an integrated two-stage ink cartridge for supplying ink to the printhead of an inkjet printer. Background Technology

[0002] The inkjet printer can print images on any material. The printing device is an essential structure. The printing mechanism includes the printing frame 1 and the secondary ink cartridge 2 and printhead 3 installed on it. The secondary ink cartridge 2 and printhead 3 are connected by ink tube 4. In order to prevent changes in the ink supply, a safety bottle is added near the secondary ink cartridge. The two are independent containers, but they are connected to each other by ink tube, which increases the instability of negative pressure and thus affects the printing effect; in addition, it also occupies some space. Utility Model Content

[0003] The purpose of this invention is to provide an integrated two-stage ink cartridge for supplying ink to the printhead of a printer. A safety chamber is designed in the two-stage ink cartridge and connected to it through a high-level overflow port, so that the safety chamber has the same function as a safety bottle. At the same time, it reduces the possibility of affecting the seal due to pipeline connections, and makes the negative pressure system for controlling inkjet more reliable.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated two-stage ink cartridge for supplying ink to the printhead of a printer, comprising a cartridge body and a cover plate. The cartridge body is divided into a safety chamber and an inkjet chamber by a partition plate, and an overflow port is provided at the upper part of the partition plate. The cartridge body is provided with an ink outlet hole that communicates with the inkjet chamber. The ink outlet hole is equipped with a valve, and the outlet of the valve is connected to the ink tube.

[0005] Preferably, a partition plate is provided inside the inkjet chamber, and the upper and lower parts of the partition plate are provided with connecting holes.

[0006] Preferably, the bottom plate of the box body has a bottom plate hole, the cover plate has a cover plate hole, and both the bottom plate hole and the cover plate hole are fitted with sealing plungers.

[0007] Preferably, the lowest point of the ink outlet hole is higher than the inner bottom surface of the cartridge body.

[0008] Preferably, a sealing groove is provided on the upper part of the box body, and the sealing groove is used to fit a sealing ring.

[0009] The technical effects of this utility model are as follows:

[0010] A safety chamber is designed in the secondary ink cartridge and connected to it through a high-level overflow port, so that the safety chamber has the same function as the safety bottle. At the same time, it reduces the possibility of the connection of pipelines affecting the seal, and makes the negative pressure system for controlling inkjet printing more reliable.

[0011] The integrated secondary ink cartridge container has several partitions inside to reduce the risk of ink surging back and forth inside during machine operation, which could affect the printhead's ability to draw in air or prevent ink from being dispensed.

[0012] The secondary ink cartridge cover and base plate have cover holes and base plate holes for ink inlet and manual ink outlet. An ink outlet is provided on the side above the inner base plate to connect to the manual valve. This is to ensure that any impurities in the ink will sink to the bottom and not be supplied into the printhead, thus preventing printhead blockage. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0019] like Figure 1-4 As shown, the technical solution of this utility model is: an integrated two-stage ink cartridge for supplying ink to the printhead of a printer, including a cartridge body 11 and a cover plate 13. The cartridge body 11 is divided into a safety chamber 15 and an inkjet chamber 16 by a partition plate, and an overflow port 17 is provided on the upper part of the partition plate. The cartridge body 11 is provided with an ink outlet 22 that communicates with the inkjet chamber 16. The ink outlet 22 is equipped with a valve 12, and the outlet of the valve 12 is connected to the ink tube 4.

[0020] The secondary ink cartridge 2 of this application is installed on the inkjet printer 1, and the outlet of the valve (generally a manual valve) 12 is connected to the printhead 3 through the ink tube 4. Ink is injected into the inkjet chamber 16 of the cartridge body 1, and then the valve is opened to perform inkjet printing. During the process of adding ink into the cartridge body 1, if too much ink is added, it will flow from the overflow port 17 into the safety chamber 15. In this way, the constant negative pressure system can control and stabilize when the ink is too full.

[0021] like Figure 4 As shown, a partition plate 18 is provided inside the inkjet chamber 16, and a connecting hole 19 is provided at the upper and lower parts of the partition plate 18.

[0022] During inkjet printing, the secondary ink cartridge 2 moves along with the printhead 1, causing the ink in the inkjet chamber 16 to circulate back and forth. This application divides the inkjet chamber 16 into several interconnected small spaces by using a partition plate 18, which reduces the amplitude of ink circulation and thus reduces the risk of the printhead sucking in air or not producing ink.

[0023] like Figure 2 and Figure 4 As shown, the bottom plate of the box body 11 has a bottom plate hole 20, and the cover plate 13 has a cover plate hole 14. Both the bottom plate hole 20 and the cover plate hole 14 are fitted with sealing plungers.

[0024] When ink needs to be added, simply open the plunger on the cover hole 14 and then add ink through the cover hole 14. When the ink cartridge needs to be cleaned, the plunger in the bottom plate hole 20 can be opened to remove any residue inside the ink cartridge.

[0025] like Figure 2-4 As shown, the lowest point of the ink outlet 22 is higher than the inner bottom surface of the housing 11. With this design, ink that may carry ink residue at the bottom layer will not enter the manual valve through the ink outlet 22, thus ensuring the printing quality of the printhead.

[0026] like Figure 4 As shown, a sealing groove 21 is provided on the upper part of the box body 11. The sealing groove 21 is used to fit the sealing ring. The box body 11 and the cover plate 13 are locked together by bolts.

[0027] The sealing groove 21, combined with the application of the sealing ring, ensures a good sealing effect at the connection between the box body 11 and the cover plate 13.
