Example two

The present application provides a liquid containing device, in which the housing 20 in the present embodiment is the same as the first embodiment, and the specific structure can refer to fig. 4. The main difference between the liquid container 12 of the present embodiment and the first embodiment is the restriction member 152. As shown in fig. 5 to 9, the present embodiment provides a liquid containing apparatus detachably mounted in the housing 20; the housing 20 comprises a bottom plate 21, the liquid container is located on the bottom plate 21, and a first end edge of the bottom plate 21 has a first notch 211.

The liquid containing device comprises a liquid containing body 12 and a connecting part 11, wherein the connecting part 11 is fixed at one end of the liquid containing body 12 close to the first notch 211, and a chip 14 is arranged at the edge of the first end of the connecting part 11 close to the bottom plate 21; the connecting member 11 includes a body and a restricting member 152, the restricting member 152 being located on a side of the body close to the bottom plate 21; the limiting member 152 of this embodiment includes a penetrating portion 152a and a fastening portion 152b, the top end of the penetrating portion 152a is fixedly connected to the main body, the bottom end of the penetrating portion 152a extends from the first notch 211 to the lower side of the bottom plate 21, the fastening portion 152b is disposed at the bottom end of the penetrating portion 152a, and a projection of the fastening portion 152b on the bottom plate 21 at least partially falls outside the first notch 211.

It should be noted that, in this embodiment, the limiting member 152 is disposed in a region corresponding to the first notch 211 at the bottom of the connecting member 11, and the limiting member 152 is hooked with the bottom plate 21 at the first notch 211, specifically, the limiting member 152 includes a penetrating portion 152a and a fastening portion 152b, a lower end of the penetrating portion 152a is located below the bottom plate 21, the fastening portion 152b is protruded from a-Y direction side of a lower end of the penetrating portion 152a, and the fastening portion 152b is abutted against a side of the bottom plate 21 facing away from the liquid accommodating body 12. That is to say, the liquid container 12 in this embodiment can realize the spacing of the casing 20 in the X and Z directions through the restriction member 152 hooked with the bottom of the bottom plate 21, because the abutting of the engaging portion 152b is below the bottom plate 21, the moving space in the Y direction is extremely small, the stable assembly of the liquid container 12 can be ensured, the liquid container 12 is not required to be provided with other connecting structures matched with the casing 20, and the connecting structure matched with the printer installation portion is not required to be provided, which helps to reduce the manufacturing cost of the related consumable. And since the restriction member 152 is relatively close to the chip 14, the contact stability of the chip 14 with the electrical connection portion of the printer can be improved.

In an alternative embodiment, as shown in fig. 4, the first notch 211 extends along the length direction of the base plate 21, and the extension length of the limiting member 152 along the width direction of the base plate 21 matches the opening width of the first notch 211.

The extending length of the restricting member 152 in the width direction of the housing 20 matches the opening width of the first notch 211 in the width direction of the housing 20. This arrangement enables both ends of the restricting member 152 to abut against both side end surfaces of the first notch 211, thereby achieving a more stable restricting effect in the X direction.

Possibly, with reference to fig. 4 and 7, the first notch 211 has a U-shaped profile, and the first notch 211 has an arc-shaped end wall surface 212, and the side of the penetrating portion 152a facing the end wall surface 212 is an arc-shaped surface, and the arc degree of the arc-shaped surface matches with the arc degree of the end wall surface 212.

It should be noted that, the penetrating part 152a is matched with the end wall surface 212 of the first notch 211, so that the arc-shaped surface of the penetrating part 152a can be better abutted against the end wall surface 212 of the first notch 211, and a more stable limiting effect can be achieved in the Y direction.

For example, as shown in fig. 8, the piercing-out portion 152a is configured as an arc-shaped rib plate, the top end of the arc-shaped rib plate is fixedly connected with the body, and the bottom end of the arc-shaped rib plate extends out of the bottom plate 21 from the first notch 211; the clamping part is set to be arc-shaped, the arc-shaped bulge is arranged on the side face of the bottom end of the arc-shaped rib plate, and the arc-shaped bulge abuts against the bottom face, back to the liquid accommodating body side, of the bottom plate 21.

It can be understood that, specifically, the piercing-out portion 152a is an arc rib plate whose side surface is attached to the end wall surface 212, and the engaging portion 152b is an arc protrusion on the side surface of the arc rib plate of the piercing-out portion 152a, and an upper surface of the arc protrusion serving as the engaging portion 152b is abutted against a lower surface of the bottom plate 21 at an edge of the end wall surface 212. By using a rib plate as the piercing-out portion 152a, the strength of the restricting member 152 can be ensured, and the risk of damage to the restricting member 152 during abutment with the bottom plate 21 can be reduced.

In one embodiment, as shown in fig. 4, the housing 20 includes a plurality of baffles surrounding the periphery of the bottom plate 21, the housing 20 further includes a second notch 225 formed in the baffles, the plurality of baffles include a front baffle 221 and side baffles 223 at two ends of the front baffle 221, and the second notch 225 is formed in the front baffle 221.

As shown in fig. 6 and 9, the connecting member 11 includes a liquid guiding-out portion 111, the liquid guiding-out portion 111 is disposed at a position corresponding to the second notch 225 on the side surface of the main body, and one end of the liquid guiding-out portion 111 departing from the main body penetrates through the second notch 225 and protrudes outside the front baffle 221.

In the present embodiment, the liquid lead-out portion 111 is a protrusion provided around the edge of the second notch 225 when viewed from the outside of the front bezel 221, and the liquid lead-out portion 111 from which ink is protruded can play a role of guiding the ink during the mounting of the liquid container 12.

The second notch 225 and the first notch 211 may or may not be in communication with each other, and may be provided according to the specific structure of the connecting member.

As to a specific connection manner of the liquid containing body 12 and the connection part 11, as shown in fig. 6, optionally, the body of the connection part 11 has a containing cavity (not shown in the figure), one end of the liquid containing body 12 close to the body is provided with a fixed joint 15, and the fixed joint 15 is clamped in the containing cavity. Namely, the liquid container 12 is connected to the body of the connecting component 11 by means of snap-fit, and then indirectly connected to the housing 20 through the body of the connecting component 11, so as to achieve connection and fixation with the printer.

To facilitate the taking in and out of the liquid containing apparatus, a gap may be provided between the body of the connecting member 11 and the front baffle 221.

Further, as shown in fig. 4, the first end of the bottom plate 21 has two protrusions 23, and at least a part of the connecting member 11 is located between the two protrusions 23.

Note that, the two protrusions 23 are structures existing on the base plate 21 itself, and the two protrusions 23 are provided at both ends of the base plate 21 in the X direction. The present application simplifies the connection structure by directly fixing the liquid container 12 to the bottom plate 21 of the housing 20 with a simple hooking structure. Therefore, when the connecting part 11 of the present application is provided, the connecting part 11 does not need to be connected with the housing 20 by the two protruding parts 23, and the two protruding parts 23 can be partially and structurally avoided.

It is possible that the distance between the end wall surface 212 of the first notch 211 and the front baffle 221 is smaller than the distance from the boss 23 to the front baffle 221, i.e., the end wall surface 212 of the first notch 211 is closer to the front baffle 221 than the boss 23. By disposing the restriction member 152 closer to the chip 14 than the projection portion 23, the contact stability of the chip 14 with the printer electrical connection portion 52 can be improved.

In a specific embodiment, as shown in fig. 4, the first notch 211 may be disposed at the middle of the first end edge of the bottom plate 21, and the second notch 225 is correspondingly disposed at the middle of the front baffle 221.
