The action mechanism 400 includes a force receiving member 41, a movable member 42 and a force conversion member connecting the force receiving member 41 and the movable member 42, in this embodiment, the force conversion member is a connection member 43, wherein the force receiving member 41 is configured to receive a downward acting force, the connection member 43 is configured as a force conversion member for transmitting the downward acting force to the movable member 42, and forcing the movable member 42 to move forward along a front-back direction, so as to release the locking between the locking surface 203 and the limiting surface 105, preferably, the elastic member 500 is combined with the force receiving member 41, and during the process of resetting the action mechanism 400, the acting force of the elastic member 500 can be more directly applied to the force receiving member 41, as shown in fig. 3, the force receiving member 41 includes a force receiving portion 411, an elastic member combining portion 412 and a limiting portion 413 connected with the force receiving portion 411, the force receiving portion 411 is further provided with a protruding rib 414 for increasing a friction force, and one end of the elastic member 500 abuts against the elastic member combining portion 412, the other end is abutted against the housing, and the limiting part 413 is combined with the housing, and is used for preventing the force-bearing member 41 from falling off from the housing and limiting the movement direction of the force-bearing member 41 to be the vertical direction.
The moveable member 42 includes a main body 421, a raised surface 422 extending from the main body 421, and a retaining surface 423 disposed adjacent to the raised surface 422. As shown in fig. 4A and 4B, when the movable element 42 does not receive the acting force, the locking surface 203 abuts against the limiting surface 105, and the unlocking assembly 300 is at the first position; when the movable member 42 receives the acting force, the main body 421 slides forward on the housing, and the lifting surface 422 lifts the second portion 202 of the locking member, so that the locking member 200 rotates integrally about the rotation axis L, and when the locking member 200 reaches above the movable member 42 integrally, the locking member 200 is held by the holding surface 423, the locking of the locking surface 203 and the stopper surface 105 is released, and the ink cartridge 100 can be taken out smoothly, with the unlocking member 300 in the second position.

Fig. 5 is a diagram showing a comparison between the state before the force is applied and the state after the force is applied to the action mechanism according to the embodiment of the present invention.
A first connection portion 43a is disposed between the connection member 43 and the force receiving member 41, and a second connection portion 43b is disposed between the connection member 43 and the movable member 42, wherein at least the second connection portion 43b is movably connected, for example, the connection member 43 and the movable member 42 are connected by a spring, a connection capable of rotating around a fixed pin, or a flexible material, so that the connection member 43 is movable relative to the movable member 42, and the connection member 43 can transmit the acting force to the movable member 42 through the second connection portion 43 b. The connection mode of the first connection portion 43a is not limited, that is, the connection between the connection portion 43 and the force-receiving member 41 may be rigid, or may be the same as the connection mode of the second connection portion 43b, in this embodiment, the connection portion 43 itself is made of an inflexible material so that the connection portion 43 does not elastically deform, and the loss of the acting force in the transmission process through the connection portion 43 can be reduced, and then, in the transmission process of the acting force from the connection portion 43 to the movable member 42 through the second connection portion 43b, even if the relative position between the connection portion 43 and the movable member 42 is not favorable for the transmission of the acting force, under the action of the acting force, the connection portion 43 can move relative to the movable member 42 by an angle, so that the connection portion 43 reaches a position which is more favorable for the transmission of the acting force to the movable member 42.
When the connecting member 43 is rigidly connected to the force-receiving member 41, as described above, the second connecting portion 43b between the connecting member 43 and the movable member 42 is movably connected, so that the connecting member 43 can move relative to the movable member 42 to a position favorable for transmitting the acting force; when the connecting member 43 and the force-receiving member 41 are movably connected, it can be understood that, after the connecting member 43 has moved by an angle relative to the movable member 42, even if the connecting member 43 is still at a position unfavorable for transmission of the acting force relative to the movable member 42, the acting force can first force the connecting member 43 to move by an angle relative to the force-receiving member 41, so that the acting force can be smoothly transmitted from the force-receiving member 41 to the connecting member 43, and then the connecting member 43 moves by another angle relative to the movable member 42, so that the acting force can be smoothly transmitted from the connecting member 43 to the movable member 42, and thus, when the first connecting portion 43a and the second connecting portion 43b are both movably connected, the acting force applied from top to bottom to the force-receiving member 41 can be more easily transmitted to the movable member 42.
Fig. 5 shows the comparison of the relative positions of the force-receiving member 41, the connecting member 43 and the movable member 42 before and after the force is transmitted to the action mechanism 400, wherein the force-receiving member 41 is limited to move only in the up-down direction, and the movable member 42 is limited to move only in the front-back direction, so that the connecting member 43 serves as a force conversion member for converting the downward force received by the force-receiving member 41 into a force for forcing the movable member 42 to move forward. When the acting force from top to bottom is applied, the force receiving member 41 moves downward along the up-down direction, the elastic member 500 is compressed and deformed, the connecting member 43 pushes the movable member 42 to move forward through the second connecting portion 43b, meanwhile, the first connecting portion 43a moves downward together with the force receiving member 41, along the front-back direction, the included angle between the connecting member 43 and the back-back direction is gradually reduced, the acting force from top to bottom is converted into the acting force/forced pushing force from back to front, the movable member 42 is forced to move forward by the distance g, and the unlocking assembly 300 moves from the first position to the second position. As can be seen from fig. 5, when the first connecting portion 43a is in the movable connection mode, in the second position, the smaller the angle between the connecting portion 43 and the backward direction is, and correspondingly, the greater the distance g that the movable member 42 moves forward is. Once the force from top to bottom is removed, the force-receiving member 41 is reset upward under the elastic reset force of the elastic member 500, and at the same time, the connecting member 43 pulls the movable member 42 to reset, so that the unlocking assembly 300 returns to the first position from the second position.

FIG. 6 is a perspective view of an action mechanism according to a second embodiment of the present invention; fig. 7 is a diagram showing a comparison between the state before the application of the force and the state after the application of the force to the working mechanism according to the second embodiment of the present invention.
For simplicity, the same components in this embodiment are numbered the same as those in the above embodiment, and as shown in fig. 6, the action mechanism 400 in this embodiment still includes the force receiving member 41, the movable member 42 and the force conversion member, in this embodiment, the force conversion member is a connecting member 43 ', the connecting member 43 ' connects the force receiving member 41 and the movable member 42, the force receiving member 41 is used for receiving a downward acting force, and the connecting member 43 ' is used as the force conversion member for transmitting the downward acting force to the movable member 42, so as to force the movable member 42 to move forward in the front-back direction, and release the locking between the locking surface 203 and the position-limiting surface 105.
As shown in fig. 6, a first connection portion 43a ' is disposed between the connection member 43 ' and the force-receiving member 41, and a second connection portion 43b ' is disposed between the connection member 43 ' and the movable member 42, wherein at least the second connection portion 43b ' is movably connected, and the specific connection manner of the first connection portion 43a ' and the second connection portion 43b ' is the same as that of the first embodiment, and is not repeated herein. In contrast, in the present embodiment, at least a portion of the connecting element 43 ' is made of an elastic material, so that the connecting element 43 ' itself can be elastically deformed, for example, at least a portion of the connecting element 43 ' is made of a plastic sheet, a thin metal sheet, or the like, accordingly, the elastic element 500 for forcing the unlocking assembly 300 to reset can be omitted, the force-receiving element 41 is still provided with the force-receiving portion 411 for receiving the acting force and the limiting portion 413 for preventing the force-receiving element 41 from falling off the housing, and the limiting portion 413 is still connected to the force-receiving portion 411.
The second connecting portion 43b ' in this embodiment is preferably movably connected, the first connecting portion 43a ' is rigidly connected, as shown in fig. 7, when the unlocking assembly 300 is at the first position, the connecting portion 43 ' is bent, that is, the connecting portion 43 ' is bent in the initial state, when a force is applied to the force-receiving portion 411 from top to bottom, the force-receiving member 41 starts to move downward and immediately pulls the connecting portion 43 ' to elastically deform, as shown in fig. 7, when the connecting portion 43 ' deforms to the maximum and the force-receiving member 41 continues to move downward, the downward force starts to be transmitted to the movable member 42 through the connecting portion 43 ' and forces the movable member 42 to move forward by a distance g, the unlocking assembly 300 moves from the first position to the second position, during which the locking member 200 rotates to the position above the movable member 42 around the rotation axis L and is supported by the movable member 42, the ink cartridge 100 can be removed. When the force from the top to the bottom is removed, the restoring force of the connecting member 43 'forces the force-receiving member 41 to move upward, and at the same time, the connecting member 43' pulls the movable member 42 to move backward, and finally, the unlocking assembly 300 returns to the first position from the second position to be reset.
In the process that the connecting member 43 ' converts the acting force from top to bottom to the acting force/thrust from back to front, the second connecting portion 43b ' is movably connected, so that the connecting member 43 ' can be angularly adjusted relative to the movable member 42, so that the acting force can be more smoothly transmitted to the movable member 42; because the connecting piece 43 'has elasticity, in the process of transmitting the acting force from the force-bearing piece 41 to the connecting piece 43', even if the two pieces are rigidly connected, the connecting piece 43 'can ensure the smooth transmission of the acting force between the two pieces by adjusting the angle of the connecting piece 43' per se; it is understood that the first connection portion 43a 'may also be in an articulated manner, in which the acting force can be delayed in the process of being transmitted from the force-bearing member 41 to the connection portion 43', and in the action mechanism 400 in which the first connection portion 43a 'is in the articulated manner, under the condition that the connection portion 43' has the same deformation amount, the distance g of forward movement of the movable member 42 will be shortened, or in other words, under the condition that the distance g of forward movement of the movable member 42 is ensured to be unchanged, the distance of downward movement of the force-bearing member 41 will be increased, and this structure is more advantageous for the ink cartridge in which the requirement for the forward movement distance of the movable member 42 is smaller or the requirement for the downward movement distance of the force-bearing member 41 is larger.

The magnetic force between the first magnetic element 615 and the second magnetic element 625 can force the movable element 62 to move in the front-back direction, so that the movable element 62 and the force-receiving element 61 can not be in contact with each other, thereby reducing the friction force between the movable element 62 and the force-receiving element 61, reducing the abrasion between the movable element 62 and the force-receiving element 61, and prolonging the service life.

The lifting surface 622 may be a plane parallel to the up-down direction, or an inclined surface inclined with respect to the up-down direction, and the lifting surface on the inclined surface is relatively more labor-saving, so that the lifting surface 622 is preferably an inclined surface, the front side of the lifting surface 622 is closer to the housing/main body 621 than the rear side thereof along the front-rear direction, and an included angle formed between the lifting surface 622 and the rear direction is an acute angle, and the smaller the included angle, the smoother the movement of the movable member 62. The second elastic member 501 is coupled to the movable member 62, one end of the second elastic member 501 abuts against the second elastic member coupling portion 624, and the other end abuts against the limiting surface 105, so that the acting force of the second elastic member 501 can reset the movable member 62 to the first position in the resetting process of the acting mechanism 600.
Fig. 10 shows the comparison of the relative positions of the force-receiving member 61, the movable member 62, the first magnetic member 615 and the second magnetic member 625 before and after the force is transmitted to the actuating mechanism 600, wherein the force-receiving member 61 is limited to move only in the up-down direction, and the movable member 62 is limited to move only in the front-back direction, so that the force applied from the top to the bottom by the force-receiving member 61 is converted into a force for forcing the movable member 62 to move forward by the repulsive force of the first magnetic member 615 and the second magnetic member 625. When a force from top to bottom is applied, the force receiving member 61 moves downward in the up-down direction, the first elastic member 500 is compressed and deformed, and at the same time, the first magnetic member 615 moves downward together with the force receiving member 61, the repulsive force between the first magnetic member 615 and the second connecting member 625 pushes the movable member 62 to move forward in the front-back direction, the second elastic member 501 is compressed and deformed, the movable member 62 is forced to move forward by a distance g, and the unlocking assembly 300 moves from the first position to the second position.
