The specific embodiment
Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the specific embodiment that accompanying drawing specifies the utility model at present.
As shown in Figure 4, in the Leakproof ink box preferred embodiment of the utility model, comprise the seal cover 2 of cartridge body 1 and sealing cartridge body 1; Like Fig. 2, shown in Figure 3, cartridge body 1 is provided with and is used to store the ink storage chamber 18 of ink and head end cushion chamber 10 and the terminal cushion chamber 19 that is communicated with, and wherein, head end cushion chamber 10 is communicated with ink storage chamber 18, and terminal cushion chamber 19 is communicated with ambient atmosphere through gas port 21; Head end cushion chamber 10 be positioned at ink storage chamber 18 the top, and be communicated with ink storage chamber 18 through air inlet 101, air inlet 101 is arranged on the chamber wall of head end cushion chamber 10.Directly be communicated with through the air inlet 101 that is arranged on the head end cushion chamber 10 chamber walls between head end cushion chamber 10 and the ink storage chamber 18, middle without elongated excessively ink path, thus can avoid capillary generation; Head end cushion chamber 10 is positioned at the top of ink storage chamber 18, and under difference variation, the ink in the ink storage chamber 18 also is difficult for entering into head end cushion chamber 10, thereby avoids ink from gas port 21 outside ink leaks.
Also be provided with sub-cushion chamber between cushion chamber 19 and the head end cushion chamber 10 endways, sub-cushion chamber is communicated with endways between the cushion chamber 19 and head end cushion chamber 10 through the air guide runner.Sub-cushion chamber is a plurality of, is communicated with successively through connected entrance or air guide runner between a plurality of sub-cushion chambers.Preferably, the air guide runner is the groove that is arranged on cartridge body 1 outside, and specifically is divided into the first air guide runner 41, the second air guide runner 42, the 3rd air guide runner 43 according to the cavity difference that is communicated with.Connected entrance specifically is divided into first connected entrance 31, second connected entrance 32 according to the cavity difference that is communicated with.
In in this enforcement, particularly, like Fig. 2, shown in Figure 3; Sub-cushion chamber is four; Be respectively first sub-cushion chamber 11, second sub-cushion chamber the 12, the 3rd sub-cushion chamber the 13, the 4th sub-cushion chamber 14 that is communicated with successively, wherein, head end cushion chamber 10 is communicated with through the first air guide runner 41 with the first sub-cushion chamber 11; The first sub-cushion chamber 11 is communicated with through first connected entrance 31 with the second sub-cushion chamber 12; The second sub-cushion chamber 12 is communicated with through the second air guide runner 42 with the 3rd son buffering 13 chambeies, and the 3rd sub-cushion chamber 13 and the 4th sub-cushion chamber 14 are communicated with between 32, the four sub-cushion chambers 14 and the terminal cushion chamber 19 through second connected entrance and are communicated with through the 3rd air guide runner 43.As shown in Figure 4, the above first air guide runner 41, the second air guide runner 42, the 3rd air guide runner 43 are the groove that is arranged on cartridge body 1 outside.Herein, the number of sub-cushion chamber is not limited thereto, and also can be one, two or other numbers; And the mode of communicating between a plurality of sub-cushion chambers also is not limited to present embodiment.
