The box body 101 and the adapter 102 are formed separately, and there is no restriction on the formation method of the two. For example, the box body 101 and the adapter 102 can be formed by injection molding and blow molding. For the box body 101 with a larger ink capacity, the box body 101 formed by blow molding is more conducive to ensuring the structural stability of the box body 101, but the technical solution involved in the utility model does not impose any restrictions on the manufacturing form of the box body 101 and the adapter 102.

[0090] The adapter 102 is provided with at least one guided portion for cooperating with the guide protrusion 2f1 on the partition 2f, so that the housing 11 can be smoothly installed and removed. Figure 3 As shown, a first guided portion 102g is disposed in front of the adapter 102 , and a second guided portion 102h is disposed in the rear of the adapter 102 ; when the housing 11 is not provided with the adapter 102 , the guided portions will be directly disposed on the housing 11 .

[0091] The adapter 102 is also provided with an unlocking protrusion 102i. Along the front-to-back direction, the unlocking protrusion 102i is arranged at the rear of the adapter 102. When the ink cartridge 10 is installed forward to the accommodating portion 2e, the unlocking protrusion 102i squeezes the pushing member 2i, causing the pushing member 2i to move forward, thereby releasing the locking of the pushing member 2i on the bottom plate 2m. Subsequently, the ink cartridge 10 can be rotated downward together with the bottom plate 2m.

[0092] The box body 101 also has an upper surface 101a facing upward, a lower surface 101b facing downward, a front surface 101c facing forward, and a rear surface 101d facing rearward, and the ink outlet 101z is arranged on the lower surface 101b of the box body; the adapter 102 is at least capable of adapting to the lower shell 109, and the adapter 102 also has an adapter lower surface 102b facing downward, and the ink outlet portion 16 is arranged on the adapter 102 and exposed downward from the adapter lower surface 102b; the chip mounting portion 11y can also be arranged on the adapter 102.

[0093] When the box body 101 is combined with the adapter 102, the lower surface 101b of the box body will be blocked by the adapter 102. At this time, at least the front surface 101c of the box body can be regarded as the front surface 11c of the shell 11, and at least the rear surface 101d of the box body can be regarded as the rear surface 11d of the shell 11, and the ink outlet 101z is opposite to the ink outlet portion 16.

[0094] Furthermore, the ink cartridge 10 also includes a locking mechanism 5 combined with the shell 11. When the ink cartridge 10 reaches a predetermined installation position, the locking mechanism 2n2 locks the locked mechanism 5, so that the ink cartridge 10 can be stably maintained in the predetermined installation position. When the ink cartridge 10 needs to be removed, the user unlocks the locked mechanism 5 by operating the locking mechanism 2n2.

[0095] [Example 1]

[0096] Figure 3 The structure in which the locked mechanism 5 is movably disposed on the adapter 102 is shown, but it should be understood that the locked mechanism 5 can also be movably disposed on the box body 101, that is, the locked mechanism 5 is movably disposed on the shell 11.

[0097] like Figure 3As shown, the adapter 102 is provided with a accommodating space 102f for accommodating the locked mechanism 5. The locked mechanism 5 involved in this embodiment includes a first reset member 51 and a locked member 52. The locked member 52 is combined with the shell 11 and is used to lock with the locking mechanism 2n2 so that the ink cartridge 10 is locked. The first reset member 51 is used to force the locked member 52 to move toward a locking position that can be locked with the locking mechanism 2n2, that is, the locked member 52 can move between the locked position and the unlocked position. In the locked position, the locked member 52 is locked with the locking mechanism 2n2, and the device-side movable member 4 is located in the first position. In the unlocked position, the locked member 52 is unlocked, and the device-side movable member 4 is located in the second position.

[0098] The locked member 52 includes a base 521, a locked portion 522 connected to the base 521, and a forced pushing portion 523. In one embodiment, the first return member 51 is configured as a compression spring, one end of which abuts against the shell 11 / adapter 102, and the other end abuts against the locked member 52 (base 521). In another embodiment, the first return member 51 can also be configured as a tension spring, one end of which is connected to the shell 11 / adapter 102, and the other end is connected to the locked member 52 (base 521).

[0099] The forced pushing portion 523 is configured as a plate-shaped body connected to the base 521 , and a contact surface 526 for contacting the lifting arm 43 is further configured on the plate-shaped body. The contact surface 526 is configured as an inclined surface inclined relative to the up-down direction.

[0100] In some embodiments, the locked member 52 also includes a locking member guide portion 524 disposed on the plate-like body. By means of the locking member guide portion 524, the movement trajectory of the locked member 52 can be precisely controlled. For example, through the locking member guide portion 524, the locked member is configured to move in the front-to-back direction, or in the up-and-down direction. Specifically, the locked member 52 moves linearly in the front-to-back direction or in the up-and-down direction.

[0101] In some embodiments, the locked member 52 further includes a limiting portion 527 disposed on the plate-like body, by means of which the relative position of the lifting arm 43 and the abutting surface 526 can be precisely controlled when the locking mechanism 2n2 and the locked mechanism 5 are locked with each other.

[0102] In some embodiments, the locked member 52 also includes a first auxiliary surface 525 disposed on the base 521, and the first auxiliary surface 525 is configured as an inclined surface inclined relative to the up and down directions. On the one hand, the first auxiliary surface 525 can prevent the locked member 52 from interfering with the locking mechanism 2n2. On the other hand, when the movable member 4 on the device side rotates along the rotation direction r3, the first auxiliary surface 525 can receive the thrust from the inclined surface 462 in the movable member 4 on the device side and accelerate the movement of the locked member 52 from the locked position to the unlocked position.

[0103] When the ink cartridge 10 rotates downward together with the bottom plate 2m, the rear elastic member is elastically deformed, and the locked portion 522 begins to abut against the first side wall 2n4, forcing the first return member 51 to be elastically deformed. At the same time, the locked portion 522 retracts into the housing 11 / adapter 102. Overall, the locked member 52 moves from the locked position to the unlocked position. When the locked portion 522 passes over the first side wall 2n4, the first return member 51 releases the return force, and the locked member 52 moves from the unlocked position to the locked position. In the locked position, the locked portion 522 enters the locking space 2n7. Specifically, the locked portion 522 enters the active space 2n0 and reaches below the first locking surface 2n41. Figure 4A , Figure 4B and Figure 4C As shown, the locked portion 522 is opposite to the first locking surface 2n41 in the up and down directions. Preferably, the locked portion 522 abuts against the first locking surface 2n41 in the up and down directions, so that the tendency of the ink cartridge 10 to move upward can be stopped; the first auxiliary surface 525 is opposite to or abuts against the inclined surface 462, and the lifting arm 43 is opposite to or abuts against the abutting surface 526.

[0104] like Figure 5A , Figure 5B and Figure 5C As shown, when the ink cartridge 10 needs to be removed, the user presses the pressed plate 42 downward, and the device side movable member 4 starts to rotate around the rotation axis L4 along the Figure 4C The lifting arm 43 abuts against the abutting surface 526, thereby forcing the locked member 52 to overcome the elastic force of the first restoring member 51 and move forward until the locked portion 522 and the first locking surface 2n41 are no longer opposite to each other in the vertical direction, or in other words, until the locking portion 522 and the first locking surface 2n41 are disengaged from the abutting contact in the vertical direction, and the locked member 52 reaches the unlocked position. Subsequently, the bottom plate 2m rotates around the accommodating portion rotation axis 2s along the elastic force released by the rear elastic member Figure 1C The ink cartridge 10 gradually rotates upward in the direction indicated by CD3, and at the same time, the ink cartridge 10 is driven by the bottom plate 2m to rotate upward, so the user can easily take out the ink cartridge 10.

[0105] During the removal process of the ink cartridge 10, as the movable part 4 on the device side rotates, the inclined surface 462 may also abut against the first auxiliary surface 525. In this way, the first auxiliary surface 525 will also be subjected to the lifting force from the inclined surface 462, thereby forcing the locked part 52 to disengage from the locking mechanism 2n2 faster.

[0106] [Example 2]

[0107] In this embodiment, the locked member 52 is configured to rotate around a rotation axis L52 extending in the left-right direction, and the locked mechanism 5 further includes an intermediate member 6 for abutting against the locked member 52, and the intermediate member 6 is movably disposed relative to the housing 11, such as Figure 6 As shown, the locked member 52 includes a base 521, a locked portion 522, a locked member rotating portion 528 and a transmission member 529. The locked portion 522 is connected to the base 521 for locking with the locking mechanism 2n2. The transmission member 529 is connected to the base 521 for transmitting unlocking force and reset force to the base 521, thereby forcing the locked member 52 to rotate around the locked member rotating portion 528 to achieve locking of the locked portion 522 with the locking mechanism 2n2 and unlocking of the locked portion 522 with the locking mechanism 2n2.

[0108] Continue as Figure 6 As shown, the locked member 52 also includes a retaining portion 5211 connected to the base 521, which is used to retain the locked member 52 in an abutting position, so that when the ink cartridge 10 rotates downward with the bottom plate 2m, the locked member 52 / the locked portion 522 can abut against the locking mechanism 2n2 and rotate in a predetermined direction, thereby achieving the locking of the locked member 52 and the locking mechanism 2n2; the transmission member 529 extends from the base 521 to form a cantilever shape, the first reset member 51 abuts against the transmission member 529 above the transmission member 529, and the intermediate member 6 abuts against the transmission member 29 below the transmission member 529, so that the transmission member 529 is clamped by the first reset member 51 and the intermediate member 6. In some embodiments, the first reset member 51 can also be configured as a tension spring. At this time, the first reset member 51 and the intermediate member 6 can be arranged on the same side of the transmission member 529.

[0109] The intermediate piece 6 includes an intermediate piece main body 61 and a force-bearing portion 62 and a limited portion 63 connected to the intermediate piece main body 61. The force-bearing portion 62 is also used to abut against the lifting arm 43, thereby forcing the locking piece 52 to rotate around the rotation axis L52, and the limited portion 63 is used to prevent the intermediate piece 6 from escaping from the ink cartridge 10.

[0110] like Fig. 7A , Figure 7B and Figure 7CAs shown, the locking portion 522 is opposite to or abuts against the first locking surface 2n41 in the up-down direction, the first reset member 51 presses the transmission member 529, and the locked member 52 has a Figure 7C The locking mechanism 5 and the locking mechanism 2n2 are locked in the direction opposite to the rotation direction r4, the lifting arm 43 is opposite to or abuts against the force-bearing part 62, the locking member 52 is located in the locked position, and the movable member 4 on the equipment side is located in the first position.

[0111] When the ink cartridge 10 needs to be removed, the user presses the pressed plate 42, and the device-side movable member 4 moves along the rotation axis L4. Figure 7C The lifting arm 43 abuts against the force-bearing portion 62 to push the intermediate member 6 upward, and then the intermediate member 6 pushes the transmission member 529, and the transmission member 529 drives the base 521 to rotate around the rotation axis L52 along the Figure 7C The rotation direction r4 rotates in the direction shown; Fig. 8A , Figure 8B and Figure 8C As shown, the locking portion 522 disengages from the abutment with the first locking surface 2n41, that is, the locked member 52 moves from the locked position to the unlocked position, the device-side movable member 4 moves from the first position to the second position, and the first reset member 51 and the device-side elastic member 2n3 are both elastically deformed. When the user no longer presses the pressed plate 42, the first reset member 51 and the device-side elastic member 2n3 release the elastic force, and the locking member 52 and the device-side movable member 4 are reset.

[0112] Similar to the first embodiment, the locked member 52 can also be provided with the above-mentioned first auxiliary surface 525. When the locked member 52 is locked, the first auxiliary surface 525 is opposite to the inclined surface 462. During the process of the locked member 52 being unlocked, the first auxiliary surface 525 will be subjected to the lifting force from the inclined surface 462, thereby forcing the locked member 52 to disengage from the locking mechanism 2n2 faster.

[0113] [Example 3]

[0114] Similar to the second embodiment, the intermediate member 6 in this embodiment is configured to be rotatable about the rotation axis L6, but different from the second embodiment, the unlocking of the locked member 52 in this embodiment is no longer through the device-side movable member 4, but through the intermediate member 6. Fig. 9 As shown, the middle piece 6 includes a middle piece rotating part 64 and a middle piece main body 61 and a force-bearing part 62 connected to the middle piece rotating part 64. The force-bearing part 62 is located at the rear of the shell 11 and is used to receive external force (such as the pressing force of the user). At the same time, the middle piece 6 is connected to the shell 11 through the middle piece rotating part 64. Therefore, the middle piece rotating part 64 can also be regarded as a limited part 63.

[0115] like Fig. 9As shown, the transmission member 529 in this embodiment is fixedly connected to the base 521, and the transmission member 529 also forms an inclined extruded surface 5291. Correspondingly, the middle member body 61 of the middle member 6 is provided with a force transmission portion 611 for abutting against the extruded surface 5291; the first reset member 51 directly abuts against the base 521, and is used to force the locked member 52 to move along the Fig. 9 The base 521 is rotated in the opposite direction to the direction indicated by r4. At the same time, the base 521 is also provided with the retaining portion 5211.

[0116] like Fig. 10A , Fig. 10B and Fig. 10C As shown, the locked portion 522 is opposite to or abuts against the first locking surface 2n41 in the up-down direction, the first reset member 51 presses the base 521, and the locked member 52 has a Fig. 10C The tendency of rotation in the opposite direction to the direction indicated by the rotation direction r4 is locked by the locking mechanism 5 and the locking mechanism 2n2.

[0117] When the ink cartridge 10 needs to be removed, the user presses the force-bearing portion 62, and the intermediate member 6 moves along the rotation axis L6. Fig. 10C The middle piece body 61 and the power transmission part 611 squeeze the squeezed surface 5921, thereby forcing the locked piece 52 to overcome the elastic force of the first reset piece 51 and move along the Fig. 10C The direction of rotation is shown by r4; Fig.11A , Fig. 11B and Fig. 11C As shown, the locking portion 522 is disengaged from the abutment with the first locking surface 2n41, that is, the locked member 52 moves from the locked position to the unlocked position, and the first return member 51 is elastically deformed. When the user no longer presses the force-bearing portion 62, the first return member 51 releases the elastic force and the locking member 52 is reset.

[0118] [Example 4]

[0119] Similar to the third embodiment, the locked member 52 in this embodiment is also configured to be unlocked by rotating along the rotation direction r4, and the unlocking of the locked member 52 in this embodiment is no longer through the device-side movable member 4, but through the intermediate member 6. Fig.12As shown, the middle piece 6 includes a middle piece body 61, a force-bearing portion 62 and a second reset piece 65. The middle piece body 61 is configured to be movable in the up and down directions. The force-bearing portion 62 protrudes backward from the middle piece body 61. The second reset piece 65 abuts against the middle piece body 61 or the force-bearing portion 62. The ink cartridge 10 also includes an abutment portion 113 extending backward from the shell 11. The second reset piece 65 is a sheet body or a compression spring arranged between the middle piece 61 and one of the force-bearing portion 62 and the abutment portion 113. The middle piece body 61 is also provided with a force transmission portion 611. In this embodiment, the force transmission portion 611 is a rack. Correspondingly, the locked piece 52 is also provided with a locked piece rotating portion 528 connected to the base 521 and a transmission piece 529 arranged on the locked piece rotating portion 528. The transmission piece 529 is at least one tooth for engaging with the rack 611. It is practicable that the tooth 529 and the rack 611 can also be interchangeable.

[0120] like Fig.13A , Fig. 13B and Fig. 13C As shown, the locked portion 522 is opposite to or abuts against the first locking surface 2n41 in the up-down direction, the first reset member 51 presses the base 521, and the locked member 52 has a Fig. 13C The tendency of rotation in the opposite direction to the direction indicated by the rotation direction r4 is locked by the locking mechanism 5 and the locking mechanism 2n2.

[0121] When the ink cartridge 10 needs to be removed, the user simultaneously grasps the abutment portion 113 and the force-bearing portion 62, applies a gripping force to the force-bearing portion 62, drives the intermediate member body 61 to move upward, and the second reset member 65 is elastically deformed. The meshing of the rack 611 and the teeth 529 forces the locked member rotating portion 528 to drive the locked member 52 to overcome the elastic force of the first reset member 51 and move along the Fig. 13C The direction of rotation is shown by r4; Fig.14A , Fig. 14B and Fig. 14C As shown, the locking portion 522 is disengaged from the abutment with the first locking surface 2n41, that is, the locked member 52 moves from the locked position to the unlocked position, and the first return member 51 and the second return member 65 are elastically deformed. When the user no longer grasps the force-bearing portion 62, the first return member 51 and the second return member 65 release the elastic force, and the locking member 52 is reset.

[0122] The abutting portion 113 and the force-bearing portion 62 in this embodiment both extend rearwardly behind the shell 11 . Therefore, the abutting portion 113 and the force-bearing portion 62 can also serve as handles of the ink cartridge 10 , making it easier for the user to install and disassemble the ink cartridge 10 .

[0123] [Example 5]

[0124] In this embodiment, the locked member 52 is provided with a first elastic arm 52a and a second elastic arm 52b that are symmetrically arranged in the left - right direction. The first elastic arm 52a and the second elastic arm 52b have the same structure, and the two are combined to form a "ji" - shaped component. Under the concept of this embodiment, only one of the first elastic arm 52a and the second elastic arm 52b can also be provided. However, regardless of the number of elastic arms provided, each elastic arm has a tendency to open in the left - right direction.

[0125] Each elastic arm includes a base 521 and a locked portion 522 connected to the base 521. The intermediate member 6 includes an intermediate member body 61 and a force - receiving portion 62 connected to the intermediate member body 61. The intermediate member body 61 abuts against the base 521. The force - receiving portion 62 includes a first portion 62a, a second portion 62b, and a third portion 62c that are connected in sequence. At least the first portion 62a is located behind the housing 11. At least a part of the second portion 62b is movably arranged below the lower surface 11b2 of the sub - housing. The third portion 62c connects the second portion 62b and the intermediate member body 61. Thus, the second portion 62b can also be regarded as the limited portion 63.

[0126] As Fig.16A and Fig. 16B shown, the locked portion 522 reaches the lower surface (second locking surface) 432 of the lifting arm 43. Although the device - side movable member 4 has a tendency to rotate around the Figure 1F rotation axis L4 in the direction shown by r3, under the elastic force of the device - side elastic member 2n3, the locked portion 522 can be locked / held on the lower surface 432 of the lifting arm 43. In this way, the locked member 52 is locked.

[0127] When it is necessary to remove the ink cartridge 10, as Fig.17A and Fig. 17B shown, the user pushes the first portion 62a forward. Through the second portion 62b and the third portion 62c, the intermediate member body 61 also moves forward. To cause the elastic arm 52a / 52b to undergo elastic deformation, for example, an inclined surface is provided on the side of the intermediate member body 61 opposite to the base 521. In this way, with the elastic deformation of the elastic arm 52a / 52b, the locked portion 522 is disengaged from abutting against the second locking surface 432, and the locked member 52 is unlocked; in another embodiment, an inclined surface may not be provided on the side of the intermediate member body 61 opposite to the base 521. Instead, by utilizing the tendency of the elastic arm itself to open in the left - right direction, when the intermediate member body 61 presses the elastic arm, the locked portion 522 is disengaged from abutting against the second locking surface 432.

[0128] When the user no longer pushes the first part 62a, the elastic arm 52a / 52b releases the elastic force, and while the locked member 52 is reset, it also pushes the middle member 6 to move backward and reset. It can be seen that the second reset member in this embodiment can also be omitted, and the unlocking process of the locked member 52 does not require the rotation of the movable member 4 on the device side to be realized.

[0129] [Example 6]

[0130] Similar to the fifth embodiment, the middle piece 6 in this embodiment is still configured to move in a translational manner, thereby releasing the lock of the locked piece 52 , but the middle piece 6 in this embodiment moves in the up-and-down direction, rather than the front-and-back direction.

[0131] like Fig.18 As shown, the middle piece 6 still includes a middle piece main body 61 and a force-bearing portion 62 connected to the middle piece main body 61, the middle piece main body 61 abuts against the base 521, the force-bearing portion 62 includes a first part 62a, a second part 62b and a third part 62c connected in sequence, at least the first part 62a is located at the rear of the shell 11, at least a part of the second part 62b is movably arranged below the sub-lower surface 11b2, and the third part 62c connects the second part 62b and the middle piece main body 61, and therefore, the second part 62b can also be regarded as the limited portion 63.

[0132] Preferably, the locked member 52 in this embodiment is also configured as a first elastic arm 52a and a second elastic arm 52b which are arranged opposite to each other in the left-right direction, and at least one of the two elastic arms has a tendency to gradually open in the left-right direction from top to bottom, such as Fig.19A and Fig.19B As shown, the locked portion 522 reaches below the lifting arm 43 , and the locked portion 522 abuts against the second locking surface 432 , and the locked member 52 is locked.

[0133] When it is necessary to remove the ink cartridge 10, Fig. 20A and Fig. 20B As shown, the user pushes the first part 62a downward, and through the second part 62b and the third part 62c, the middle piece body 61 also moves downward. With the elastic deformation of the elastic arm 52a / 52b, the locked part 522 disengages from the abutment with the second locking surface 432, and the locked piece 52 is unlocked.

[0134] When the user no longer pushes the first part 62a, the elastic arm 52a / 52b releases the elastic force, and while the locked member 52 is reset, it also pushes the middle member 6 in the opposite direction to move upward and reset. It can be seen that the second reset member in this embodiment can also be omitted, and the unlocking process of the locked member 52 does not require the rotation of the movable member 4 on the device side to be realized.

[0135] [Example 7]

[0136] The ink cartridge 10 in this embodiment further includes a pressed member 18 combined with the housing 11. Specifically, the pressed member 18 is disposed on the upper surface 11a of the housing 11. The pressed member 18 includes a force-bearing surface 181 facing the front and upper side, a retaining surface 183 located above the force-bearing surface 181, and a second auxiliary surface 182 facing the rear. Preferably, the pressed member 18 is configured to slide on the housing 11 in the front-to-back direction. Fig.21 As shown, the pressed member 18 is further provided with a protrusion as a guided member 184, and correspondingly, the housing 11 is provided with a guide groove 11a2 as a guide member.

[0137] Different from the above-mentioned embodiment, the locking mechanism in this embodiment is a locking groove 11a1 arranged on the shell body 11, and the locked mechanism is a locked protrusion 185 arranged on the pressed piece 18. The ink cartridge 10 can be first installed forward to the accommodating portion 2e, and then the door cover 3 is directly closed. During the closing process of the door cover 3, the pressing portion 3b squeezes the second auxiliary surface 182, pushing the pressed piece 18 to slide forward until the locked protrusion 185 enters the locking groove 11a1. At the same time, the force surface 181 abuts against the upper side plate 2a of the main component 2 of the device, and the ink cartridge 10 and the bottom plate 2m rotate downward around the accommodating portion rotation axis 2s. Finally, the ink cartridge 10 reaches the predetermined installation position and is locked.

[0138] It is understandable that the protrusion 184 and the guide groove 11a2 can also be interchanged, and the locking groove 11a1 and the locked protrusion 185 can also be interchanged.

[0139] [Embodiment 8]

[0140] Different from the seventh embodiment, the ink cartridge 10 in this embodiment is locked in the imaging device by combining the locked protrusion 185 provided on the pressed member 18 with the locking groove 2a1 provided on the upper side plate 2a, and the components and locking process of this embodiment that are the same as those of the seventh embodiment are not repeated.

[0141] Furthermore, the ink cartridge locking structures in Example 7 and the present embodiment can also be combined with each other, that is, the locked protrusions in Example 7 and the present embodiment are simultaneously provided in the ink cartridge 10, and the locking grooves are simultaneously provided on the shell 11 and the upper side plate 2a, so that the ink cartridge 10 can be more stably locked in the imaging device.

[0142] [Example 9]

[0143] In the case of the inventive concept of the above embodiment, the shell 11 of the ink cartridge 10 provided in this embodiment is manufactured by injection molding, such as Fig.23As shown, the ink cartridge 10 includes a bottom shell 106 and a surface cover 107 which are separated in the upper and lower directions, and the bottom shell 106 and the surface cover 107 are both formed by injection molding, and a cavity for containing ink is formed therebetween, and the cavity includes an ink cavity 106a and a sponge cavity 106b which are interconnected in the front-to-back direction, and the ink outlet portion 16 is directly connected to the sponge cavity 106b, and the sponge 104 as a negative pressure generating member is installed in the sponge cavity 106b.

[0144] Furthermore, the ink cartridge 10 also includes a handle 103 connected to the shell 11. The handle 103 can be formed integrally with the shell 11 or connected to the shell 11 in a detachable manner. When the user needs to install or remove the ink cartridge 10, the user combines the handle 103 with the shell 11. After the installation or removal is completed, the handle 103 is removed. In this way, the handle 103 will not occupy the space in the imaging device, and accordingly, the volume of the cavity does not need to be reduced.

[0145] In order to achieve the connection between the cavity and the external atmosphere, the shell 11 is also provided with an air guide hole 1071 and an air guide membrane 1072 for sealing the air guide hole. Although the figure shows that the air guide hole 1071 is arranged on the face cover 107, it should be understood that the setting position of the air guide hole should not be limited, as long as the cavity can be connected with the atmosphere through the air guide hole.

[0146] [Example 10]

[0147] Different from the ninth embodiment, the bottom shell 106 and the surface cover 107 in this embodiment are combined in the left-right direction. As shown in the figure, the bottom shell 106 is open to the left. In order to improve the sealing performance of the ink cartridge 10, the ink cartridge 10 also includes a sealing film 105 covering the cavity on the left or right. Along the left-right direction, the sealing film 105 is located between the bottom shell 106 and the surface cover 107.

[0148] [Other Notes]

[0149] The above-mentioned embodiment focuses on describing that the locked portion 522 abuts against the first locking surface 2n41 or the second locking surface 432 in the locking mechanism 2n2 to achieve the locking of the ink cartridge 10. However, it can be understood that the locked portion 522 can also enter at least one of the upper locking space 2n55 and the lower locking space 2n56 in the locking mechanism 2n2 to achieve the locking of the ink cartridge 10.

[0150] Compared with the locking mechanism described in the background technology which is combined with the groove set at the rear end of the ink cartridge, in the utility model, any one of the first locking surface 2n41, the second locking surface 432, the upper locking space 2n55 and the lower locking space 2n56 has a deeper combination depth (the dimension in the front-to-back direction) than the groove, so that the ink cartridge 10 can be more stably locked in the imaging device; further, the locking mechanism in the background technology is configured to be retractable, while the first locking surface 2n41, the upper locking space 2n55 and the lower locking space 2n56 in the utility model are all immovable. It can be seen that the ink cartridge 10 involved in the utility model can be more stably locked in the imaging device.
