When the imaging device does not inflate the deformable cavity, the one-way valve opens the air inlet to enable the ink storage cavity to be communicated with the outside atmosphere, so that negative pressure generated by consumption of ink in the ink storage cavity is eliminated, and smooth flowing of the ink is facilitated. When the imaging device inflates the deformable cavity through the inflation port, the deformable cavity drives the one-way valve to close the air inlet, so that the ink in the ink storage cavity can continuously flow out.

However, in the existing ink cartridge, since the air inlet is directly communicated with the ink storage cavity, a small amount of ink may leak from the air inlet, even though a waterproof air-permeable member may be disposed at the air inlet, the sealing performance of the waterproof air-permeable member is relatively limited, and the air permeability of the waterproof air-permeable member is greatly affected by the ink adhered to the surface of the waterproof air-permeable member; in addition, when imaging device aerifys to the flexible intracavity, in order to prevent that the ink can reveal or break waterproof ventilative piece and take place to reveal from the air inlet, the ink horn still need set up the check valve and seal the air inlet for the structure of ink horn is comparatively complicated, has improved manufacturing cost, has reduced the packaging efficiency.

In order to solve the technical problem, the application provides an ink box, which at least comprises a box body and a deformation piece, wherein an accommodating cavity is formed in the box body, and the deformation piece is arranged in the accommodating cavity to divide the accommodating cavity into a first cavity and a second cavity; the box body is also internally provided with a separation part which separates the first cavity into an ink storage cavity and a buffer cavity, and the ink storage cavity is communicated with the outside atmosphere through the separation part and the buffer cavity.

Specifically, after the image forming apparatus is installed in the image forming apparatus, the ink supply mechanism may suck out the ink stored in the ink cartridge 100 and transfer the ink to the print head 210, the print head 210 may print the ink on the medium 250 according to a pre-printed image, the air supply mechanism 220 may continuously or discretely input a certain amount of fluid (e.g., gas) into the ink cartridge 100 as needed to change the pressure in the ink cartridge 100, so that the ink may continuously flow out, the driver 240 may control the print head 210 and/or the platform storing the medium 250 to displace, and the controller 230 may be configured to control the operating state of any one of the foregoing mechanisms.

For convenience of understanding and explanation, the length direction of the ink cartridge 100 is set in advance as the X-axis direction shown in fig. 2, the thickness direction of the ink cartridge 100 is set in advance as the Y-axis direction shown in fig. 2, and the width direction of the ink cartridge 100 is set in advance as the Z-axis direction shown in fig. 2, where the X-axis, the Y-axis, and the Z-axis intersect with each other. Preferably, the X, Y and Z axes are perpendicular to each other.

Further, when the air supply mechanism 220 is not operated, the air charging port 11 may correspond to an air guide port to communicate with the outside atmosphere. The air supply mechanism 220 can be inflated from the inflation opening 11 to the second chamber, so that the ink in the ink storage chamber 151a can be continuously squeezed out, and the ink supply efficiency of the ink cartridge 100 is improved. Because the second cavity and the first cavity are separately arranged, compared with the existing ink box, the ink box does not need to be additionally provided with a one-way valve and other mechanisms to seal the air inlet 13, so that the structure of the ink box 100 is simplified, the production cost is reduced, and the assembly efficiency is improved.

When the ink storage cavity 151a is filled with ink, the deformation member 4 expands and deforms in the direction close to the face cover 16 to increase the volume of the ink storage cavity 151a, the support plate 5 moves along with the deformation member 4 in the direction close to the face cover 16, and at this time, the elastic member 6 is in a stretching state to store elastic potential energy; as the ink in the ink storage cavity 151a is continuously consumed, the elastic member 6 releases the elastic potential energy to drive the supporting plate 5 to move in the direction away from the face cover 16, and the deformation member 4 contracts and deforms in the direction away from the face cover 16 to reduce the volume of the ink storage cavity 151 a.

In addition, when the air supply mechanism 220 inflates air to the second chamber, under the action of air pressure, the deformation member 4 contracts and deforms in the direction away from the face cover 16 to reduce the volume of the ink storage cavity 151a, so that ink in the ink storage cavity 151a is squeezed out, in the process, the supporting plate 5 and the elastic member 6 can provide a buffer effect for deformation of the deformation member 4, and the air pressure is prevented from directly acting on the deformation member 4 to force the deformation member 4 to break.

Referring to fig. 6 to 9, in some embodiments, the deformable member 4 includes a main body 41, an escape portion 42 and an escape groove 43, wherein the escape portion 42 protrudes from a surface of the main body 41 facing the face cover 16 to a direction close to the face cover 16, so that the surface of the deformable member 4 facing away from the face cover 16 is formed with the escape groove 43.

Further, a valve body structure (not shown) such as a self-sealing valve is further disposed in the ink outlet 12, and when the ink supply mechanism is inserted into the ink outlet 12, the ink supply mechanism can drive the self-sealing valve to open the ink outlet 12, so that the ink in the ink storage cavity 151a can flow from the ink outlet 12 to the ink supply mechanism; when the ink supply mechanism is removed from the ink outlet 12, the self-sealing valve can automatically return to the initial state to seal the ink outlet 12, so as to prevent the residual ink in the ink storage chamber 151a from flowing out from the ink outlet 12 to cause pollution.

Specifically, the absorbent member 7 may be made of sponge, fiber, or any other material capable of absorbing liquid, and is not limited herein. In the present embodiment, the absorbent member 7 may be a porous sponge. Since the air pressure outside the case body 1 is greater than the air pressure inside the ink storage chamber 151a, the outside air can also bring a part of the ink absorbed by the absorbing member 7 into the ink storage chamber 151a through the connecting flow path 9 after being sucked from the air inlet 13.

The first buffer groove 151c is connected between the connection flow path 9 and the ink storage chamber 151a, and the second buffer groove 156 is connected between the connection flow path 9 and the buffer chamber 151b. The specific structure of the first buffer groove 151c and the communication with the connection flow path 9 and the ink storage chamber 151a are the same as those of embodiment 6, and the specific structure of the second buffer groove 156 and the communication with the connection flow path 9 and the buffer chamber 151b are the same as those of embodiment 7, and therefore, the description thereof is omitted.

Compared with the prior art, the utility model provides an in the ink horn 100, after this ink horn 100 was packed into imaging device and entered into the printing state, along with the ink in the ink storage chamber 151a constantly by the consumption, form certain negative pressure in the ink storage chamber 151a, the outside air can get into in the ink storage chamber 151a through partition 152 and buffer chamber 151b in proper order in order to eliminate the negative pressure, the atmospheric pressure balance performance of ink horn 100 has been improved, be favorable to the ink to flow smoothly, through setting up buffer chamber 151b, compared with current ink horn, the communication path between external atmosphere and the ink storage chamber 151a has been prolonged, a small amount of ink in the ink storage chamber 151a will flow in the buffer chamber 151b, and the non-directness is flowed from in the ink horn 100, the sealing performance of ink horn 100 has been promoted.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
