The embodiment of the application provides an ink box, and more ink is pressed into a printing head from an ink storage cavity when a printer works. As shown in fig. 1 to 4, the ink cartridge includes: the gas control valve comprises a box body 1, an auxiliary cavity 13 and a gas control valve 3, wherein the box body 1 is provided with a deformation cavity 11 and an ink storage cavity 12, the box body 1 is further provided with a gas filling port 14 communicated with the deformation cavity 11 and an ink outlet port 15 communicated with the ink storage cavity 12, the auxiliary cavity 13 is arranged in the ink storage cavity 12 and close to the deformation cavity 11, the gas control valve 3 is located in the auxiliary cavity 13, the deformation cavity 11 is filled with gas through the gas filling port 14, the gas control valve 3 is enabled to expand or displace, and the ink storage cavity 12 is enabled to be communicated with the auxiliary cavity 13 in a fluid mode. As shown in fig. 6 to 10, the deformation chamber 11 and the ink storage chamber 12 are separated by the deformation member 2, the gas control valve 3 has a valve body 32 and a valve chamber 33, the valve chamber 33 and the auxiliary chamber 13 are separated by the valve body 32, and the valve chamber 33 and the deformation chamber 11 are communicated by the gas passage 16. During the process of inflating the deformable cavity 11 through the inflation port 14, the deformable member 2 can deform, so that the gas in the deformable cavity 11 enters the valve cavity 33 through the gas passage 16, and the valve body 32 drives the volume of the auxiliary cavity 13 to become smaller, so as to drive the ink in the auxiliary cavity 13 to enter the ink storage cavity 12 and be discharged from the ink outlet 15.

In the present embodiment, as shown in fig. 1 to 4, the case 1 has an inner cavity, and the case 1 is provided with a plurality of partitioned inner cavities which can be a deformable cavity 11, an ink storage cavity 12, and the like. The deformation piece 2 separates the deformation cavity 11 and the ink storage cavity 12, and the deformation piece 2 is easy to deform, so that the volumes of the deformation cavity 11 and the ink storage cavity 12 are changed. When the ink box is mounted on a carriage (not shown) of a printer, the inflation inlet 14 of the ink box is in fluid connection with a pump (not shown) of the printer, that is, the pump can inflate the inflation inlet 14, when the pump does not work, the inflation inlet 14 can be communicated with the outside atmosphere as an air guide opening, and air enters the ink storage cavity 12 of the ink box through the inflation inlet 14 to adjust the internal air pressure balance. The ink outlet 15 of the ink cartridge is connected to a sub-ink chamber (not shown) of the printing apparatus of the printer, i.e. the ink flowing out of the ink outlet 15 can enter the print head of the printing apparatus.

As shown in fig. 7, before printing starts, a pump of the printer inflates air into the deformation chamber 11 through the inflation port 14, the deformation piece 2 deforms, the deformation chamber 11 expands, and presses the ink in the ink storage chamber 12, so that the ink flows out from the ink outlet 15, meanwhile, as shown in fig. 8 and 9, the air in the deformation chamber 11 enters the valve chamber 33 through the air passage 16, the valve body 32 deforms, so that the volume of the valve chamber 33 increases, the volume of the auxiliary chamber 13 decreases, the ink in the auxiliary chamber 13 is driven to enter the ink storage chamber 12, and then flows out from the ink outlet 15, and the ink blowing amount of the ink cartridge to a printing head of the printing device when the pump inflates air into the ink cartridge is increased, so that the ink supply of the ink cartridge is sufficient. The process of ink flowing out from the ink storage chamber 12 through the ink outlet 15 is shown in fig. 10.

As shown in fig. 2, since the volume of the ink storage chamber 12 is large and the auxiliary chamber 13 can store a part of the ink, the ink cartridge has a strong capacity of containing the ink. Meanwhile, when the pump of the printer inflates air to the deformation cavity 11 to reduce the volume of the ink storage cavity 12, because the volume of the ink storage cavity 12 is large, the pressure change in the ink storage cavity 12 is small (namely, the volume of the ink storage cavity 12 is small in proportion to the total volume of the ink storage cavity 12), and the speed of ink flowing out from the ink outlet 15 is not too high, so that on the basis of ensuring enough ink blowing amount, the ink can be uniformly discharged into the ink amount detection cavity of the printing head from the ink outlet 15, and the phenomenon that the deformation cavity is deformed due to inflation, the internal pressure of the ink storage cavity is increased too high instantly, the instant impact force of the ink flowing into the ink amount detection cavity of the printing head is large, the inner membrane in the ink amount detection cavity is damaged, and the printing device is damaged due to the fact that the ink storage cavity and the check valve are arranged inside the ink storage cavity with small volume is avoided.

Further, as shown in fig. 7, a second elastic member 6 is disposed on a side of the deformation member 2 away from the deformation chamber 11, one end of the second elastic member 6 abuts against the deformation member 2, and the other end abuts against the bottom wall of the box body 1.

When the ink volume detection chamber of the printing head in the printing device detects ink, the pump of the printer stops inflating the deformation chamber 11, the printer starts printing, the deformation part 2 recovers deformation under the elastic action of the second elastic part 6, and the valve body 32 recovers deformation. As the printing proceeds, the printhead continuously pumps ink, the ink in the ink storage chamber is gradually consumed, the volume of the ink in the ink storage chamber is gradually reduced, and a certain negative pressure is maintained in the ink storage chamber 12, so that the bubbles above the auxiliary chamber 13 are discharged into the ink storage chamber 12. Meanwhile, the situation that the negative pressure in the ink storage cavity 12 is too small, so that ink leaks through the ink outlet 15 in a non-printing state to influence the use experience is prevented. Further, the second elastic member 6 may be a spring, a silicon rubber, or the like.

In a specific embodiment, as shown in fig. 3 and 9, the gas passage 16 is a groove provided on the case 1, the deformation chamber 11 is provided with a first communication hole 111, and the gas passage 16 communicates the first communication hole 111 and the valve chamber 33.

In the present embodiment, as shown in fig. 3, the gas passage 16 is formed by providing a groove on the cartridge body 1, so that the structure of the ink cartridge is simple and the production process is facilitated. Specifically, the deformation chamber 11 is provided with a first communication hole 111 on a side away from the deformation element 2, and the gas in the deformation chamber 11 can flow into the gas passage 16 through the first communication hole 111 and further flow into the valve chamber 33, so that the volume of the valve chamber 33 is increased.

In a specific embodiment, as shown in fig. 4 and 9, the valve body 32 is provided with a second communication hole 321, and the gas in the deformation chamber 11 can enter the auxiliary chamber 13 through the first communication hole 111, the gas channel 16 and the second communication hole 321.

In a specific embodiment, as shown in fig. 9, the gas control valve 3 further includes a valve cover 31, the valve cavity 33 is located between the valve body 32 and the valve cover 31, the first elastic member 5 is disposed in the auxiliary cavity 13, one end of the first elastic member 5 abuts against the valve body 32, and the other end is connected to the bottom wall of the auxiliary cavity 13.

As shown in fig. 9, when the gas in the deformation chamber 11 enters the valve chamber 33 through the gas passage 16, the valve cover 31 is separated from the valve body 32, the second communication hole 321 communicates the valve chamber 33 and the auxiliary chamber 13, and since the gas pressure in the valve chamber 33 is large, the ink in the auxiliary chamber 13 is difficult to flow into the valve chamber 33 through the second communication hole 321; when the pump of the printer stops working, the valve body 32 rapidly recovers deformation under the action of the first elastic piece 5, the valve cover 31 is abutted with the valve body 32, the second communication hole 321 is blocked by the valve cover 31, and the auxiliary cavity 13 is not communicated with the valve cavity 33, so that ink in the auxiliary cavity 13 cannot leak through the second communication hole 321. Further, the first elastic member 5 may be a spring, silicon rubber, or the like.

Specifically, as shown in fig. 2, the auxiliary chamber 13 communicates with the ink storage chamber 12 through a fourth communication hole 132, and the fourth communication hole 132 may be provided in plurality to make the flow of ink between the auxiliary chamber 13 and the ink storage chamber 12 smoother.

In the present embodiment, as shown in fig. 4, 5 and 9, when at least a portion of the projection 322 extends into the housing groove 311, the projection 322 abuts against the bottom wall of the housing groove 311, so that the sealing performance of the gas control valve 3 with respect to the second communication hole 321 is improved, and the possibility of leakage of the ink in the auxiliary chamber 13 through the second communication hole 321 is reduced.

In a specific embodiment, as shown in fig. 4, 5 and 9, the protrusion 322 and the receiving groove 311 are both annular.

In the present embodiment, the valve body 32 achieves adjustment of the volumes of the valve chamber 33 and the auxiliary chamber 13 by expanding deformation in the direction in which the support column 131 extends, thereby increasing the ink supply amount of the ink cartridge.

In a particular embodiment, the valve body 32 is movable relative to the bonnet 31; during the process of inflating the deformation chamber 11 through the inflation port 14, the valve body 32 can be displaced in a direction approaching the auxiliary chamber 13, so as to reduce the volume of the auxiliary chamber 13; after the inflation of the deformation chamber 11 is stopped, the valve body 32 can move in a direction close to the bonnet 31.
