[0048] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0049] The consumable box, such as an ink cartridge, undertakes the task of supplying ink to a printing device. After the ink cartridge is installed into the printing device, the detection rod of the printing device reciprocates to press the deformation part of the consumable box, so as to judge the ink amount, thereby providing a warning before the ink is exhausted, and avoiding air from entering the inkjet head of the printing device.

[0050] In some ink cartridges, an adjusting member is usually arranged in the communication channel which communicates the detection cavity and the ink storage cavity. However, in the use process, the instability of the adjusting member can easily cause gas to appear in the detection cavity. When the detection rod cooperates with the deformation part, the detection rod reciprocates rapidly, so that the printing machine incorrectly identifies the information that the ink cartridge is exhausted, thereby affecting the normal use of the ink cartridge.

[0051] The embodiment of the utility model provides a consumable box, which increases the reciprocation time of the detection rod by increasing the height of the detection cavity, thereby avoiding the incorrect identification of the ink amount information by the printing machine.

[0052] The consumable box provided by the embodiment of the utility model will be described below with reference to the drawings.

[0053] Reference Figure 1 , Figure 2 and Figure 3As shown, the utility box provided by the embodiment of the utility model includes: ink storage part 10, connecting piece 20, detection part 40 and deformation part 50, the ink storage part 10 has ink storage cavity 11 for storing ink inside; connecting piece 20 is connected to the top end of ink storage part 10, and connecting piece 20 has base plane 21 facing away from ink storage cavity 11.

[0054] Detection part 40 extends from base plane 21 to the direction away from ink storage cavity 11, deformation part 50 is arranged at the top end of detection part 40, and detection cavity 41 is enclosed between detection part 40 and deformation part 50; deformation part 50 has abutting surface 51, when the utility box supplements ink to the printing device, abutting surface 51 and detection rod 90 of the printing device abut each other, and the distance H between abutting surface 51 and base plane 21 satisfies: H is greater than or equal to 10 mm.

[0055] The embodiment of the utility model provides a kind of utility box, because deformation part 50 is arranged at the top end of detection part 40, and detection cavity 41 is enclosed between detection part 40 and deformation part 50, detection part 40 has abutting surface 51, when the utility box supplements ink to the printing device, abutting surface 51 and detection rod 90 of the printing device abut each other, and the distance H between abutting surface 51 and base plane 21 satisfies: H is greater than or equal to 10 mm, increase the distance H between abutting surface 51 and base plane 21, so, when deformation part 50 is extruded by detection rod 90, the deformable distance of deformation part 50 along the depth direction of detection cavity 41 increases, i.e. the reciprocating motion distance of detection rod 90 increases, when the reciprocating motion speed of detection rod 90 is unchanged, the reciprocating motion time of detection rod 90 increases, so that in the case where the amount of ink in detection cavity 41 is sufficient, the sensor of the printing device is difficult to receive twice optical signal in shorter time, effectively solve the technical problem that printing device is prone to misidentification ink depletion information when the amount of ink in detection cavity 41 is sufficient.

[0056] In a possible implementation manner, the distance H between abutting surface 51 and base plane 21 can be 11 mm, 12 mm, 13 mm, for example.

[0057] In a possible implementation manner, the distance H between abutting surface 51 and base plane 21 satisfies H is greater than or equal to 14 mm, for example, the distance H between abutting surface 51 and base plane 21 satisfies 14 mm≤H≤20 mm.

[0058] In a possible implementation manner, the distance H between abutting surface 51 and base plane 21 can be 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm or 20 mm, for example.

[0059] Reference Figure 3As shown, the connecting piece 20 further comprises an ink outlet pipe 30 extending from the base plane 21 to a direction away from the ink storage cavity 11, the ink outlet pipe 30 internally forms an ink outlet channel 31, and an ink outlet 32 is formed at a distal end of the ink outlet pipe 30 away from the ink storage cavity 11. The detection cavity 41 is in communication with the ink outlet channel 31, and the detection cavity 41 is in communication with the ink storage cavity 11.

[0060] Since the detection cavity 41 is in communication with the ink outlet channel 31, and the detection cavity 41 is in communication with the ink storage cavity 11, under the action of an external force, the ink inside the ink storage cavity 11 will flow into the detection cavity 41, and then be supplied to the printing device through the ink outlet pipe 30.

[0061] In a possible implementation manner, the detection part 40 can be in a hollow tubular structure, and one end of the detection part 40 can be fixedly connected to the connecting piece 20.

[0062] In a possible implementation manner, as shown in Figure 2 and Figure 3 As shown, the deformation part 50 can be a flexible member, for example, made of rubber or silica gel material, when the detection rod 90 extrudes the deformation part 50, the deformation part 50 can elastically deform itself, so that the volume in the detection cavity 41 decreases, and the ink in the detection cavity 41 is extruded out of the ink outlet pipe 30, to realize ink supply to the printing device.

[0063] In the embodiment of the utility model, since the deformation part 50 is arranged at the top end of the detection part 40, the top end of the detection cavity 41 has flexible deformation capability, and the lower half of the detection cavity 41 does not have flexible deformation capability under the support of the detection part 40, when the detection rod 90 moves towards the deformation part 50, the detection rod 90 extrudes the deformation part 50, the deformation part 50 moves towards the detection cavity 41, the height of the deformation part 50 decreases at the same time, and the volume in the detection cavity 41 decreases at the same time, so that the ink in the detection cavity 41 is extruded out, and the accuracy and stability of ink amount detection are improved.

[0064] In a possible implementation manner, in a cross section perpendicular to the depth direction of the detection cavity 41, the area S of the cross section of the detection cavity 41 satisfies: S≥200mm2. Wherein, as shown in Figure 3 the Y axis indicates the depth direction of the detection cavity 41, which is also the height direction of the consumable box.

[0065] For example, the area S of the cross section of the detection cavity 41 satisfies: 200mm2≤S≤400mm2

[0066] In a possible implementation manner, the area S of the cross section of the above-mentioned detection cavity 41 can be, for example: 200mm2, 220mm2, 250mm2, 280mm2, 300mm2, 320mm2, 350mm2, 380mm2 or 400mm2.

[0067] Since the reciprocating movement stroke of the detection rod 90 and the flow rate of the ink are controlled by the printing device as fixed values, when the detection rod 90 moves a unit distance, the amount of ink that needs to be squeezed out is a constant value, therefore, when the cross-sectional area S of the detection cavity 41 increases, in order to ensure that the amount of ink squeezed out is constant, the movement speed of the detection rod 90 needs to be reduced, because a larger cross-sectional area will cause more ink to be squeezed out at the same movement speed, so the movement speed of the detection rod 90 needs to be reduced, reducing the movement speed of the detection rod 90 will increase the reciprocating movement time of the detection rod 90, and it is difficult for the sensor of the printing device to receive two light signals in a short time, effectively solving the technical problem that when the amount of ink in the detection cavity 41 is sufficient, the printing device is prone to incorrectly identifying the ink depletion information, thereby improving the detection accuracy.

[0068] The present application, because the cross-sectional area S of the detection cavity 41 is large, the reciprocating movement time of the detection rod 90 is increased, the reciprocating movement time of the detection rod 90 is longer, which helps to more accurately detect the state of the ink, reduces the technical problem that the printing device is prone to incorrectly identifying the ink amount information, and improves the accuracy of ink detection.

[0069] In a possible implementation manner, referring to Figure 4 As shown in the figure, the length L1 of the detection cavity 41 satisfies: L1≥20mm; and the width L2 of the detection cavity 41 satisfies: L2≥10mm.

[0070] In a possible implementation manner, referring to Figure 4 As shown in the figure, the length L1 of the detection cavity 41 satisfies: 20mm≤L1≤40mm; and the width L2 of the detection cavity 41 satisfies: 10mm≤L2≤20mm.

[0071] In order to increase the cross-sectional area S of the detection cavity 41, at least one of the length L1 of the detection cavity 41 and the width L2 of the detection cavity 41 can be increased. By controlling the length L1 of the detection cavity 41 and the width L2 of the detection cavity 41, it is helpful to ensure the effective movement of the detection rod 90 in the detection cavity 41, thereby improving the accuracy of detecting the amount of ink and reducing detection errors caused by improper size.

[0072] In a possible implementation manner, the length L1 of the detection cavity 41 may, for example, be 20mm, 25mm, 28mm, 30mm, 35mm or 40mm.

[0073] In a possible implementation manner, the width L2 of the detection cavity 41 may, for example, be 10mm, 12mm, 14mm, 15mm, 18mm or 20mm.

[0074] In a possible implementation manner, referring to Figure 3And Figure 4 As shown, the detection cavity 41 is provided with an elastic member 42, two ends of the elastic member 42 abut against the deformation portion 50 and the inner bottom wall of the detection cavity 41 respectively, the elastic member 42 is used to improve the elastic reset ability of the deformation portion 50, when the detection rod 90 leaves the deformation portion 50, it ensures that the deformation portion 50 can be reset, and prepares for the next deformation of the deformation portion 50.

[0075] In a possible implementation, the elastic member 42 can be a compression spring or an elastic sleeve.

[0076] In a possible implementation, the inner bottom wall of the detection cavity 41 is provided with a first positioning protrusion 411, the deformation portion 50 has a second positioning protrusion 53 facing the detection cavity 41, one end of the elastic member 42 is sleeved on the first positioning protrusion 411, and the other end of the elastic member 42 is sleeved on the second positioning protrusion 53, which improves the stability of the installation of the elastic member 42 and prevents the elastic member 42 from falling off.

[0077] In a possible implementation, the connecting member 20 has a communication channel 22, and the detection cavity 41 and the ink storage cavity 11 are in communication through the communication channel 22. The ink stored in the ink storage cavity 11 enters the detection cavity 41 through the communication channel 22.

[0078] In a possible implementation, the minimum inner diameter D of the communication channel 22 is ≤1.6 mm. The purpose is to limit the passage of bubbles in the ink through the communication channel 22, reduce the flow rate of the ink, increase the time of the ink passing through the communication channel 22, and thus improve the detection accuracy.

[0079] Because the bubbles are in the ink, the flow speed of the ink is unstable, which affects the accuracy of detection. By making the minimum inner diameter D of the communication channel 22 ≤1.6 mm, the passage of bubbles can be effectively limited, thereby reducing the interference of bubbles on the flow of ink and the detection process, and improving the reliability of the ink amount detection.

[0080] In a possible implementation, the minimum inner diameter D of the communication channel 22 can be, for example, 1 mm, 1.2 mm, 1.5 mm or 1.6 mm.

[0081] In a possible implementation, with reference to Figure 3 And Figure 5As shown, the communication channel 22 includes a first communication channel 221, which includes a first channel 2211 and a second channel 2212. The top end of the first channel 2211 is in communication with the detection cavity 41, and the top end of the second channel 2212 has a first inlet 2213 in communication with the ink storage cavity 11. The bottom ends of the first channel 2211 and the second channel 2212 can be sealed by a sealing film, and the first channel 2211 is provided with a through hole at a position close to the bottom end, which allows the bottom ends of the first channel 2211 and the second channel 2212 to communicate with each other.

[0082] Of course, in other possible implementations, the bottom ends of the first channel 2211 and the second channel 2212 can also be communicated by a communication pipe formed by plastic.

[0083] In one possible implementation, the first channel 2211 and the second channel 2212 both extend in a straight line, and the extension direction of the first channel 2211 is consistent with the extension direction of the second channel 2212. In such a structure, the first communication channel 221 is in a U shape, which prevents bubbles from passing through by virtue of the curved shape, because bubbles are more likely to be captured or retained in the curved channel, thereby reducing detection errors caused by bubble interference and improving detection reliability. In the present embodiment, the extension direction of the first channel 2211 and the extension direction of the second channel 2212 are both along the direction indicated by the arrow Y in FIG. 6. Figure 3

[0084] In other possible implementations, the extension direction of the first channel 2211 and the extension direction of the second channel 2212 have an included angle therebetween, so that the first communication channel 221 can also be in a V shape. This can also reduce detection errors caused by bubble interference and improve detection reliability.

[0085] In one possible implementation, the minimum inner diameter D of the communication channel 22 is located at a position where the bottom end of the first channel 2211 and the bottom end of the second channel 2212 communicate with each other. When ink flows from the second channel 2212 to the first channel 2211, a change in flow direction occurs at the bottom end of the second channel 2212. Bubbles are likely to be retained or dispersed in the process of changing the flow direction, thereby reducing the movement of bubbles in the ink. This is because when bubbles encounter a sharp change in flow direction, inertia will cause the bubbles to be more likely to be trapped at the position where the flow direction changes. Bubbles are also likely to be "clamped" by the curved section of the communication channel 22 to prevent bubbles from continuing to move within the communication channel 22. By providing the first channel 2211 and the second channel 2212 with different flow directions, the movement of bubbles is effectively prevented, reducing detection errors caused by bubble interference and improving detection reliability.

[0086] In the present example, reference is made to Figure 3 and Figure 5 ​As shown, the ink stored in the ink storage cavity 11 enters the second channel 2212 from the first inlet 2213, flows from the top end of the second channel 2212 to the bottom end of the second channel 2212, and then enters the first channel 2211 from the bottom end of the second channel 2212. Subsequently, the ink entering the first channel 2211 enters the detection cavity 41 through the top end of the first channel 2211.

[0087] In one possible implementation, referring to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the communication channel 22 includes a second communication channel 222, the second communication channel 222 includes a third channel 2221 and a fourth channel 2222, the third channel 2221 is in communication with the fourth channel 2222, the top end of the third channel 2221 is in communication with the detection cavity 41, and the fourth channel 2222 is provided with a second inlet 2223 in communication with the ink storage cavity 11.

[0088] In one possible implementation, the sidewall of the third channel 2221 is provided with an opening 2224, and the third channel 2221 is in communication with the fourth channel 2222 through the opening 2224. The opening 2224 can be a circular hole, an elliptical hole, or a rectangular hole, etc.

[0089] In one possible implementation, the minimum inner diameter D of the communication channel 22 is located at the position where the sidewall of the third channel 2221 is in communication with the fourth channel 2222, i.e., the position of the opening 2224. When the ink flows from the fourth channel 2222 to the third channel 2221, the flow direction changes, and bubbles are easily trapped or dispersed in the process of changing the flow direction, thereby reducing the movement of bubbles in the ink. Because when bubbles encounter a sharp change in flow direction, inertia will cause them to be more easily trapped at the position where the flow direction changes, thereby effectively preventing the movement of bubbles and reducing detection errors caused by bubbles, improving the reliability of detection.

[0090] In one possible implementation, the third channel 2221 and the fourth channel 2222 are both provided in the connecting body 24 of the connecting piece 20.

[0091] In this example, the ink stored in the ink storage cavity 11 enters the fourth channel 2222 from the second inlet 2223, and then enters the third channel 2221 from the position of the opening 2224 provided in the sidewall of the third channel 2221. Subsequently, the ink entering the third channel 2221 enters the detection cavity 41 through the top end of the third channel 2221.

[0092] In one possible implementation, the third channel 2221 and the fourth channel 2222 have an included angle between the extension directions thereof.

[0093] In a possible implementation, the included angle between the extension direction of the third channel 2221 and the extension direction of the fourth channel 2222 can be 80°, 90°, or 120°, etc., so that the second communication channel 222 is approximately L-shaped.

[0094] The utility model embodiment provides a consumable box, through design the geometric structure of communication channel 22, to limit the movement of bubble, thereby reduce the interference of bubble, help to ensure the continuity of ink flow and the reliability of detection result.

[0095] In a possible implementation, referring to Figure 4 and Figure 5 , the end of the communication channel 22 extending into the detection cavity 41 is an outlet portion 223; the ink entering the communication channel 22 enters the detection cavity 41 through the outlet portion 223.

[0096] In a possible implementation, referring to Figure 3 , Figure 4 and Figure 10 , the utility model embodiment further comprises an adjusting member 60, the adjusting member 60 comprises a head portion 65 and a rod portion 66 connected to the head portion 65, the rod portion 66 is movably arranged in the communication channel 22, and the head portion 65 movably abuts against the outlet portion 223.

[0115] The printer has a control mechanism for pushing the detection rod 90 to displace towards the direction of the consumable box, and when the detection rod 90 abuts against the deformation part 50, the detection rod 90 is at the first position, and when the ink in the variable volume cavity 201 is completely consumed, the detection rod 90 abuts against the deformation part 50 to the second position of the variable volume cavity 201, that is, the detection position.

[0116] The printer also has a detection unit, which is an optical detection unit, and the detection unit includes a light emitting part and a light receiving part. The lower side of the detection rod 90 of the printer is connected with a shielding plate, and the shielding plate is located between the light emitting part and the light receiving part. When the ink in the ink storage cavity 11 is not consumed, the detection rod 90 abuts against the deformation part 50 to move from the first position to the second position, and the deformation part 50 is also deformed towards the detection cavity 41.

[0117] The consumable box is installed in the mounting part of the printer, and the consumable box is inverted so that the ink outlet 32 is connected with the ink supply mechanism in the printer, the ink supply needle in the ink supply mechanism presses the ball valve arranged in the ink outlet 32 and enters the ink outlet 32, and the control mechanism is arranged in the printer, the control mechanism is used for pushing the detection rod 90 to displace towards the direction of the consumable box, and the detection rod 90 abuts against the deformation part 50, and at this time, the deformation part 50 is at the first position.

[0118] The embodiment of the utility model provides a consumable box, and the working process is:

[0119] When the consumable box is in the full-ink state, that is, the ink storage cavity 11 and the detection cavity 41 are filled with ink, the adjusting part 60 is slightly deformed towards the direction close to the outlet part 223 under the first action force, that is, the extrusion force applied to the temporarily stored ink in the detection cavity 41 by the detection rod 90 abutting against the deformation part 50. At this time, the sealing part 61 of the adjusting part 60 abuts against the end face of the outlet part 223, and the sealing between the adjusting part 60 and the outlet part 223 is realized, at this time, the deformation part 50 is located outside the detection part 40, and the detection rod 90 abutting against the deformation part 50 is at the first position, that is, the initial position, and there is no ink flow between the ink storage cavity 11 and the detection cavity 41.

[0120] When the ink supply mechanism in the printer applies suction force to the ink outlet 32, the ink temporarily stored in the detection cavity 41 is sucked out through the ink outlet 32, that is, the ink temporarily stored in the detection cavity 41 is supplied to the ink supply mechanism of the printer. Since the detection rod 90 applies abutting force to the ink in the detection cavity 41 through the deformation portion 50, that is, the deformation portion 50 is pressed towards the inside of the detection cavity 41, the ink temporarily stored in the detection cavity 41 can be supplied to the ink supply unit of the printer through the ink outlet 32, so that the printer can supply the ink without applying a large suction force. As the ink in the detection cavity 41 is consumed, the detection rod 90 displaces the deformation portion 50 towards the direction close to the detection cavity 41. When the ink in the detection cavity 41 is completely consumed, the detection rod 90 abuts against the deformation portion 50 to enter the second position, that is, the detection position, of the detection cavity 41.

[0121] When the detection rod 90 abuts against the deformation portion 50 to enter the second position of the detection cavity 41, the shielding member moves with the detection rod 90, and the elastic member 42 in the detection cavity 41 restores the deformation force. Under the second action of the elastic member 42 on the deformation portion 50, the deformation portion 50 displaces towards the direction away from the detection cavity 41. During the recovery of the deformation portion 50 to the initial shape, the negative pressure value in the detection cavity 41 increases.

[0122] When the deformation portion 50 recovers to the initial shape, the current negative pressure value in the detection cavity 41 just reaches the opening value of the adjusting member 60, and then the sealing portion 61 of the adjusting member 60 displaces towards the direction away from the end face of the outlet portion 223 under the action of the external force. The ink stored in the ink storage cavity 11 enters the detection cavity 41 through the outlet portion 223 under the action of gravity, and the ink in the detection cavity 41 is supplemented. During the whole process, the ink supply to the printer is not stopped.

[0123] As the ink in the detection cavity 41 is continuously filled, the negative pressure value in the detection cavity 41 decreases. When the negative pressure value is lower than the opening value of the adjusting member 60, the adjusting member 60 closes the outlet portion 223. At this time, the control mechanism drives the detection rod 90 to displace towards the direction close to the deformation portion 50 and be in the first position abutting against the deformation portion 50. The sealing portion 61 of the adjusting member 60 slightly deforms towards the direction close to the outlet portion 223 due to the first action force, so as to enhance the sealing property of the adjusting member 60 and the outlet portion 223, and prevent the ink temporarily stored in the detection cavity 41 from flowing back to the ink storage cavity 11. The above process is repeated.

[0124] When the ink in the ink storage chamber 11 is completely consumed, the ink in the consumption detection chamber 41 is started to be consumed. At this time, the above-mentioned first detection cycle is repeated, wherein the detection cycle is that the detection rod 90 is displaced from the first position initially abutting against the deformation portion 50 to the second position, and then is displaced from the second position to the first position and is displaced to be away from the abutment against the deformation portion 50, and the second position is the detection position of the detection rod 90 abutting against the deformation portion 50 and entering into the detection chamber 41.

[0125] When the control mechanism drives the detection rod 90 to be displaced towards the deformation portion 50, the detection rod 90 abuts against the deformation portion 50, and does not stay in the first position, but is directly displaced to the second position. The shielding member is moved along with the movement of the detection rod 90, so that the light emitted by the light emitter is received by the light receiver, and the signal is fed back to the control unit. That is, when the control unit continuously detects the light passage signal in two adjacent detection cycles, it is indicated that the ink in the detection chamber 41 is consumed, that is, the ink is exhausted.
