[0029] like Figures 1-6 As shown, this embodiment of the ink cartridge for a photo printer has a dual-layer filter chamber. The ink cartridge is a single-channel ink cartridge, comprising a frame 01. The top and bottom of the frame 01 are respectively provided with a pagoda-shaped ink inlet 02 and an ink outlet 03. The frame 01 has an ink inlet hole 012 and an ink outlet hole 013, with the ink inlet hole 012 communicating with the ink inlet 02 and the ink outlet hole 013 communicating with the ink outlet 03. The frame 01 has two open surfaces enclosed by a frame, and the two open surfaces are sealed by a flexible sealing film.
[0030] A partition 04 is provided in the frame 01, which divides the inner cavity of the frame 01 into a first chamber 10 and a second chamber 20 for guiding ink flow. The first chamber 10 and the second chamber 20 are connected through a flow guide hole. The first chamber 10 or the second chamber 20 is provided with at least one double-layer filter chamber 11. Either the first chamber 10 or the second chamber 20 is also provided with a pressure chamber 23 with a switching valve. The other of the first chamber 10 and the second chamber 20 is provided with a flow guide chamber 12 that communicates with the pressure chamber 23. The ink inlet nozzle 02 is connected to the double-layer filter chamber 11. The double-layer filter chamber 11 is connected to either the flow guide chamber 12 or the pressure chamber 23. The other of the flow guide chamber 12 and the pressure chamber 23 is connected to the ink outlet nozzle 03.
[0031] Specifically, the first chamber 10 is provided with a double-layer filter chamber 11, a flow guide chamber 12, and a flow guide channel 15. The second chamber 20 is provided with a pressure chamber 23, and the partition 04 is provided with a flow guide hole 040. The ink nozzle 02 is connected to the double-layer filter chamber 11 through the ink inlet hole 012. The double-layer filter chamber 11 is connected to the flow guide chamber 12 through the flow guide channel 15. The flow guide chamber 12 is connected to the pressure chamber 23 through the flow guide hole 040. The pressure chamber 23 is connected to the ink outlet nozzle 03 through the ink outlet hole 013.
[0032] The double-layer filter cavity 11 is in a triple-frame shape, and comprises a first frame 111, a second frame 112 and a third frame 113 from inside to outside. The third frame 113 surrounds the second frame 112, and the second frame 112 surrounds the first frame 111. The first frame 111, the second frame 112 and the third frame 113 are each formed by a protruding wall plate with the end surface of the partition plate 04 as a base surface. The third frame 113 protrudes to the height of the open surface of the frame body 01, and the second frame 112 protrudes to a height lower than that of the third frame 113 and higher than that of the first frame 111.
[0033] The double-layer filter cavity 11 comprises a first filter screen 114 and a second filter screen 115. The first filter screen 114 is laid on the first frame 111, and the second filter screen 115 is laid on the second frame 112. The cavity formed between the first filter screen 114 and the partition plate 04 is a pre-filtering cavity 116, the cavity formed between the first filter screen 114 and the second filter screen 115 is a middle-filtering cavity 117, and the cavity formed between the second filter screen 115 and the open surface of the frame body 01 is a post-filtering cavity 118. The ink nozzle 02 is connected to the pre-filtering cavity 116 through the ink inlet hole 012, and the post-filtering cavity 118 is connected to the flow guide cavity 12 through the flow guide channel 15. In this embodiment, the area of the double-layer filter cavity 11 accounts for 30% to 60% of the area of the first chamber 10, the area of the first filter screen accounts for 50% to 70% of the area of the double-layer filter cavity, and the area of the second filter screen accounts for 60% to 90% of the area of the double-layer filter cavity.
[0034] The flow guide cavity 12 is provided with a first disc 126, a first spring 128 and a sealing member 129. The first disc 126 covers the upper opening of the flow guide cavity 12, the sealing member 129 covers the flow guide hole 040, and the two ends of the first spring 128 are elastically abutted against the first disc 126 and the sealing member 129, respectively. Through the elastic abutment of the first spring 128, the sealing member 129 is elastically pressed on the flow guide hole 040 to block the flow guide hole 040.
[0035] The pressure cavity 23 is provided with a second disc 236, a push rod 237 and a second spring 238. The second disc 236 covers the upper opening of the pressure cavity 23, and the outer surface of the second disc 236 is connected with the inner surface of the flexible sealing film. The second disc 236 moves in and out with the flexible sealing film. The inner surface of the second disc 236 is fixedly connected with one end of the push rod 237, and the other end of the push rod 237 is suspended. The suspended end of the push rod 237 penetrates the flow guide hole 040 and is connected with the sealing member 129. The second spring 238 is sleeved on the push rod 237, and the two ends of the second spring 238 are elastically abutted against the second disc 236 and the partition plate 04, respectively.
[0036] The first disc 126, the first spring 128, the sealing member 129, the second disc 236, the push rod 237 and the second spring 238 jointly form a switch valve for stopping the ink from flowing in.
[0037] The working principle of the ink cartridge of the photo printer of the embodiment is as follows: ink enters the pre-filtering chamber 116 from the ink inlet 02, enters the middle filtering chamber 117 through the first filter screen 114, enters the post-filtering chamber 118 through the second filter screen 115, and enters the flow guide chamber 12 through the flow guide channel 15. In the flow guide chamber 12, the second disc 236 is pushed inward by the flexible sealing film of the second chamber 20 under the action of atmospheric pressure due to the negative pressure in the ink cartridge, the push rod 237 pushes the sealing member 129 outward to move away from the flow guide hole 040 along with the inward movement of the second disc 236, the flow guide hole 040 is opened, the on-off valve is opened, and the ink can enter the pressure chamber 23 from the flow guide chamber 12, at this time, the first spring 128 and the second spring 238 are in a compressed state. The internal pressure of the second chamber 20 can push the second disc 236 to reset after rising, the two springs are also elongated to reset, and the sealing member 129 also returns to the state of being pressed on the flow guide hole 040, the flow guide hole 040 is blocked, the on-off valve is closed, and the ink stops being delivered.
[0038] In other embodiments, the first frame and the second frame for supporting the filter screen can be formed by protruding inwardly based on the inner wall of the third frame to form a surrounding edge, so that the areas of the pre-filtering chamber, the middle filtering chamber and the post-filtering chamber are equal, forming a three-fold square frame type.
[0039] Compared with the prior art, the ink cartridge of the photo printer of the embodiment innovatively adopts a double filtering chamber, and the ink is filtered twice in one chamber. Such a design has at least two good effects: one is that the ink is effectively purified and impurities are discarded to ensure that the ink outlet is not blocked; the other is that the ink is gradually filtered out through the double-layer filter screen, effectively reducing the impact force of the ink on the inner cavity of the ink cartridge during the flow process, adjusting the flow rate of the ink, and effectively avoiding uneven distribution of the sprayed ink caused by uneven flow rate. Moreover, the embodiment mainly utilizes three ink guide chambers to guide the ink, reduces the use of the ink guide channel, avoids local accumulation of the ink, and ensures smooth flow of the ink.
[0040] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. For those skilled in the art, it can be understood that the embodiments can be changed, modified, replaced and modified in various ways without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
