[0009] Preferably, the suction cover is in contact with the ink box, and the sealing ring is in contact with the suction cover. The sealing ring can increase the sealing performance between the cover plate and the suction cover.

[0010] Preferably, one end of the tension spring is fixedly connected to the suction cover, and the other end of the tension spring is fixedly connected to the cover plate. The tension spring can drive the cover plate to automatically reset through elastic force.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model adds a filter box, a filter sponge and a filter material to the ink box. During the ink feeding process, the fine sediment inside the filter material and the filter sponge can be filtered, thereby effectively preventing the sediment from clogging the printer's nozzle.

[0013] 2. The utility model adds a suction cover, a cover plate and a float ball and other structures inside the ink tank.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The outside of the refueling port of the ink box 4 is connected with a sealing cover 8 through a threaded connection, the pump body tube 10 is movably connected to the threaded cover 9, and the ink box 4 can be sealed by the sealing cover 8. The filter sponge 12 is in contact with the threaded cover 9, the filter sponge 12 is in contact with the pump body tube 10, the filter material 13 is in contact with the guide tube 11, and the filter material 13 is in contact with the threaded cover 9. The filter sponge 12 can filter the sediment inside the ink.

[0023] See also Figure 1 、 Figure 3 、 Figure 5 The locking cam 77 is fixedly secured to the bottom of the bottle 78, which is secured on the left side of the bottle 78. The locking cam 77 is secured on the left side of the bottle 78. The locking cam 77 is secured on the right side of the bottle 78. When the locking cam 77 is unlocked, open the bottle and type in the event of a fire.

[0024] The specific implementation process of the utility model is as follows: when in use, the pump body inside the printing cover 3 is started, the pump body tube 10 generates suction, and the suction force is transmitted to the inside of the suction cover 71 through the negative pressure tube 6. The suction cover 71 can suck the ink inside the ink box 4 into the inside of the filter box 5. The ink is filtered by the filter material 13 and the filter sponge 12 inside the filter box 5 and then enters the inside of the pump body tube 10, which can effectively prevent sediment from entering the inside of the printing cover 3;

[0025] When the pump body absorbs the ink inside the ink tank 4, the ink liquid level inside the ink tank 4 drops. When the liquid level drops to a certain height, the buoyancy of the liquid level on the float 76 is less than the tension of the tension spring 74. The tension spring 74 drives the cover plate 72 to reset through the tension, and the cover plate 72 drives the sealing ring 73 to slide into the interior of the suction cover 71 by turning over, so that the suction cover 71 can be sealed when the liquid level is low to prevent air from entering the interior of the pump body.
