In some embodiments, the case 21 is further provided with a limiting portion 25, when the elastic member 233 is pressed, the elastic member 233 abuts against an end portion of the limiting portion 25 and is limited by the limiting portion 25, so that the end portion of the elastic member 233 is limited in movement, the elastic member 233 is compressed, and the elastic member 233 has sufficient elastic potential energy.

Specifically, in the present embodiment, the limiting portion 25 is a protrusion provided on the second surface 20b of the case 21, and along the Z direction, the protrusion is located on the +z direction side of the second connection section 2332. When the second connecting section 2332 of the elastic member 233 contacts the second surface 20b, the upper end surface of the end 2332a of the second connecting section 2332, which is close to the second surface 20b, abuts against the lower end surface of the protrusion, and the protrusion limits the second connecting section 2332 to move continuously in the +z direction after contacting the second surface 20b, so that the elastic member 233 does not move in the +x direction and only deforms continuously in the X direction when deformed and elastic member 233 accumulates elastic potential energy after contacting the second surface 20b, so that when the elastic member 233 returns to the initial state and all the elastic potential energy is released, the elastic member 233 only moves in the X direction, thereby helping the handle 23 to return to the initial state in the X direction to the maximum extent. In addition, the protrusion can provide a stable connection point for the free end 231 of the elastic member 233 when contacting the elastic member 233, optimize stress, guide the elastic member 233 to deform orderly, and enhance local structural strength of the corresponding stress area on the case 21. The number and shape of the protrusions are not limited, as long as the second connection section 2332 can be limited to move in the Z direction after contacting the second surface 20 b.

Referring to fig. 6 and 7, in the present embodiment, during the mounting and removal of the ink cartridge 20, the engagement portion 232 interferes with the second side wall 10B of the mounting portion 10, the engagement portion 232 receives the force or component force of the second side wall 10B in the +x direction, so that the body 231 of the handle 23 is elastically deformed in the X direction, the body 231 rotates about the first rotation fulcrum 2313, the first angle a is reduced, the elastic member 233 located between the body 231 and the second surface 20B contacts the second surface 20B and receives the force applied by the second surface 20B in the-X direction, and the second angle B and the third angle C are reduced.

When the ink cartridge 20 is in the mounted state, the force applied to the engagement portion 232 by the engagement groove has a component in +x direction and a second component in-Z direction, wherein the first component rotates the handle 23 about the first rotation pivot 2313, the first angle +.a is reduced, and the elastic member 233 between the body 231 and the second surface 20b contacts the second surface 20b without force interaction therebetween. Alternatively, the elastic member 233 is compressed after contacting the second surface 20B in the mounted state, and the second angle B and the third angle C are reduced, i.e., the handle 23 is slightly deformed in the mounted state.

Example two

As shown in fig. 8, in another ink cartridge 20 according to the present utility model, in comparison with the first embodiment, the elastic member 233 has only the first connecting section 2331 and no second connecting section 2332, and therefore, the third angle C is also not included.

Specifically, in the present embodiment, the first connection section 2331 extends in the same direction as in the first embodiment, that is, extends from the body 231 toward the second surface 20b and is inclined in a direction approaching the first surface 20 a.

Correspondingly, in the present embodiment, the limiting portion 25 is located on the-Z direction side of the limiting portion 25 in the first embodiment, that is, the protrusion is located on the-Z direction side of the first connecting section 2331. When the first connecting section 2331 of the elastic member 233 contacts the second surface 20b, the lower end surface of the end portion of the first connecting section 2331 near the second surface 20b abuts against the upper end surface of the protrusion, the protrusion limits the continuous movement of the first connecting section 2331 in the-Z direction after contacting the second surface 20b, so that the elastic member 233 does not deform in the Z direction and only continues to deform in the X direction after contacting the second surface 20b, and the elastic member 233 accumulates elastic potential energy, so that when the elastic member 233 returns to the initial state and releases all the elastic potential energy, the elastic member 233 only moves in the-X direction, thereby maximally boosting the handle 23 in the X direction to return to the initial state.

The movement range of the body 231 of the handle 23, that is, the movement range of the body 231 can be restricted by the restricting portion 25, in which the elastic member 233 does not move in the-Z direction after the protrusion abuts against the elastic member 233, and the elastic member 233 is not easily compressed in the X direction, so that the body 231 can be prevented from moving in the direction approaching the case 21, and the movement range of the body 231 can be restricted.

The elastic member 233 in this embodiment can also be elastically deformed, and in the process of recovering the initial state, the engaging portion 232 of the boosting handle 23 is recovered to the initial state, so as to achieve the same beneficial effects.

In this embodiment, the other structures on the ink cartridge 20 and the structure of the printing apparatus are the same as those in the first embodiment, and will not be described here.

Example III

As shown in fig. 9, in the present embodiment, the extending direction of the first connecting section 2331 and the position of the limiting portion 25 are opposite to those in the second embodiment, compared with the second embodiment, for the ink cartridge 20 according to the present utility model.

Specifically, in the present embodiment, the first connection section 2331 extends from the body 231 toward the second face 20b and is inclined in a direction approaching the fourth face 20 d.

Further, the position of the limiting portion 25 in the present embodiment is identical to the position of the limiting portion 25 in the second embodiment. It should be noted that, on the second surface 20b, the convex-Z direction side has a groove, and the upper wall surface of the groove (i.e. the convex lower surface) limits the second connection section 2332 to move continuously in the +z direction after contacting the second surface 20b, so that the elastic member 233 will not deform in the Z direction and only continuously deform in the X direction after contacting the second surface 20b, and the elastic member 233 accumulates elastic potential energy, so that when the elastic member 233 returns to the initial state and releases all the elastic potential energy, the elastic member 233 only moves in the-X direction, thereby helping the handle 23 to return to the initial state in the X direction to the greatest extent.

Preferably, the second rotation point in the present embodiment is located on the-Z direction side of the first rotation point in the second embodiment.

In this embodiment, the other structures on the ink cartridge 20 and the structure of the printing apparatus are the same as those in the first embodiment, and will not be described here.

In the ink cartridge 20 of the present utility model, when the handle 23 is elastically deformed, approaches or abuts against the second side wall 10b, and is kept in such a state for a long time (for example, when the handle 23 is squeezed while the ink cartridge 20 is in a packaged state, or when the ink cartridge 20 is left in the mounting portion 10 but is not mounted, or when the ink cartridge 20 is repeatedly subjected to a mounted state and a taken-out state due to multiple uses), the handle 23 body 231 loses part of the restoring ability and cannot be restored in place, and the elastic member 233 moves away from the second side wall 10b due to its own elastic restoring force, thereby driving the handle 23 to completely restore the elastic deformation away from the second side wall 10, reducing the risk that the body 231 cannot be completely restored to an initial state, and the engaging portion 232 provided on the body 231 is located on the-X direction side of the engaged portion 14 when the ink cartridge 20 is mounted again in the mounting portion 10, and cannot be smoothly engaged with the engaged portion 14.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
