Description

Technical Field

[0001] The utility model relates to an ink supply mechanism for an ink cartridge.

Background Art

[0002] For the original ink cartridge of a printer, after the ink is used up after working for a period of time, since there is no ink replenishing port configured, users can only purchase the same type of ink cartridge for replacement. However, the price of the original ink cartridge is relatively high, resulting in a high use cost. Therefore, some people recycle the ink cartridge for cleaning and processing to become the recycled ink cartridges that appear on the market later. The advantage of the recycled ink cartridge is that users can replenish ink later and the use cost is reduced. However, each time it is also necessary to remove the recycled ink cartridge and use a syringe to replenish ink, which is very troublesome.

[0003] Therefore, it is necessary to make further improvements to it.

Detailed Embodiment

[0014] In order to deepen the understanding of the utility model, the utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the utility model and do not limit the protection scope of the utility model.

[0015] Please refer to Figure 1 , this application provides an ink supply mechanism for an ink cartridge, which includes an ink cartridge body 1 and an ink supply container 2. An ink storage cavity 1 is formed inside the ink cartridge body. A sponge body 3 is arranged in the ink storage cavity. An ink separation area 4 is provided at the inner top of the ink cartridge body 1. An air passage communicating with the ink storage cavity is opened in the ink separation area. An air permeable valve 5 is provided at the top of the ink cartridge body corresponding to the inside of the ink separation area. A supply pump 6 and a supply cavity 7 are arranged in the ink supply container. The input end of the supply pump communicates with the supply cavity, and the output end of the supply pump communicates with the ink storage cavity through an ink supply pipe 8. A control panel 9 is arranged on the ink supply container to control the operation of the supply pump. When the ink cartridge body runs out of ink or the printer gives an ink shortage alarm, the supply pump is controlled to transport and supplement ink into the ink cartridge body. Therefore, users do not need to disassemble the ink cartridge to replenish ink, which also brings great convenience to users in use.

[0016] A vertically extending strip-shaped transparent window 10 is provided on the cavity wall of the supply cavity 7. Marks are provided at the highest point and the lowest point of the strip-shaped transparent window, which are the MAX mark corresponding to the maximum ink storage capacity and the MIN mark corresponding to the lowest ink level point respectively. Users can know the ink content in the supply cavity through the strip-shaped transparent window, so as to replenish ink in time.

[0017] To prevent users from forgetting to refill the ink, a liquid sensor 11 is provided inside the ink supply chamber. The liquid sensor is located near the bottom of the ink supply chamber. An indicator light 12 is provided on the ink supply container. The indicator light operates according to the sensing signal of the liquid level sensor. When the liquid level sensor is triggered, the indicator light will immediately light up to remind the user.

[0018] A baffle 13 is provided in the ink storage chamber 1. The baffle and the chamber wall of the ink storage chamber enclose an ink inlet channel 14. The bottom of the ink inlet channel is the ink outlet. The ink supply pipe is connected to the ink inlet channel. This structure can prevent ink from spraying towards the ink storage chamber, and the ink input into the ink storage chamber slowly wets the sponge body.

[0019] A partition 15 is provided at the inner top of the ink cartridge body 1. The partition and the top wall of the ink supply chamber enclose the ink separation area 4. The partition abuts against the bottom of the sponge body 3, which can fix the sponge body to always contact the ink outlet at the bottom of the ink cartridge body. The ink separation area is used to discharge the air inside the ink cartridge body to ensure that ink can be smoothly replenished into the ink storage chamber.

[0020] The air vent valve includes a plug 51. An air chamber 52 is formed inside the plug. A plurality of micro pores 53 are distributed at the top of the plug. A plurality of exhaust holes 54 are distributed on both sides of the bottom of the plug. The micro pores are communicated with the air chamber, and the exhaust holes are communicated with the air chamber. The air in the ink storage chamber can enter the air chamber through the exhaust holes and then be discharged from the micro pores. This structure can prevent ink leakage. Preferably, a duckbill-shaped ink return port 55 is provided at the bottom of the plug. The exhaust holes are located above the ink return port. The duckbill-shaped ink return port has the advantages of being difficult for ink to enter and easy for ink to return, and can return the ink that enters the air chamber back through the ink return port.

[0021] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention should be included in the protection scope recorded in the claims.
