Example two

The present application provides a liquid containing apparatus, in which the housing 20 of 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 first end edge 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 the present 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 the 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, the liquid container 12 in this embodiment can be limited upwards in the X and Z directions by the limiting member 152 hooked to the bottom of the bottom plate 21, and the engaging portion 152b abuts against the bottom plate 21, so that the moving space in the Y direction is very small, the stable assembly of the liquid container 12 can be ensured, other connecting structures matched with the casing 20 do not need to be arranged on the liquid container 12, and the connecting structure matched with the printer installation portion does not need to be arranged, which helps to reduce the manufacturing cost of related consumables. And because the restraint members 152 are closer to the chip 14, the stability of the contact of the chip 14 with the electrical connections of the printer is 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 makes it possible to bring both ends of the restricting member 152 into abutment with both side end faces of the first notch 211, thereby achieving a more stable restricting action 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 of the arc-shaped surface matches with the arc 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 provided with an arc bulge, the arc bulge is arranged on the side face of the bottom end of the arc rib plate, and the arc bulge is abutted 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 the rib plate as the piercing part 152a, the strength of the restricting part 152 can be ensured, and the risk of damage to the restricting part 152 during the 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 be connected or not connected, and may be provided according to the specific structure of the connecting member.

As to a specific connection mode 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. That is, the liquid container 12 is connected to the body of the connecting component 11 by clipping, 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.

In order to facilitate the taking and placing of the liquid containing device, a gap may be provided between the body of the connection member 11 and the front barrier 221.

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

Note that the two projections 23 are structures existing on the base plate 21 itself, and the two projections 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 flap 221. The first notch 211 and the second notch 225 are disposed at the middle position to correspond to the position of the fixed joint 15 on the liquid container 12, so as to directly correspond to the fixed joint 15, thereby reducing the complexity of the process and facilitating the discharge of the ink in the liquid container 12.

In the embodiment, a plurality of ribs are densely arranged at the bottom of the connecting member 11, and the bottom surface of the rib at the side close to the front baffle 221 at the bottom of the connecting member 11 is inclined and flush, so that the guide inclined surface 115 is actually the bottom surface of the ribs and can be understood as a discontinuous set of a plurality of narrow surfaces. Fig. 13 to 14 illustrate a specific structure of the restricting member 152 and a specific connection relationship between the piercing portion and the engaging portion in this embodiment.

When the liquid container 12 is installed, the end of the connecting member 11 having the liquid guiding portion 111 may be abutted against the front baffle 221, and abutted against the front baffle 221 at the guiding inclined plane 115, so that the liquid container 12 can slide into the casing 20 along the guiding inclined plane and be clamped with the bottom plate 21, and the guiding inclined plane can ensure that the sliding assembly process of the liquid container 12 is smooth and free from jamming.

In the X-axis direction, the transition portion 114 is located between the two convex portions 23, the length of the transition portion 114 is smaller than the length of the front portion 113, and the length of the limiting member 153 is larger than the length of the front portion 113.

Both ends of the limiting piece 153 are abutted against the side baffle 223 on the corresponding side, the bottom of the limiting piece 153 is at least partially attached to the upper surface of the bottom plate 21, and the thickness of the limiting piece 153 is smaller than that of the connecting part 11. A concave part 153a for avoiding the liquid containing body 12 is arranged in the middle of the limiting part 153, the height of the concave part 153a is smaller than or equal to the thickness of the limiting part 153, and the length of the concave part 153a along the X-axis direction is smaller than the length of the side edge of the transition part 114 close to the rear baffle 222. In addition, the bottom of the connecting member 11 is also provided with a guide slope 115 on a side close to the front baffle 221. Introducing the concave portions 153a can reduce interference of the restriction members 153 with the liquid container 12, and in the present embodiment, the height of the concave portions 153a in the Z-axis direction is equal to the thickness of the restriction members 153 in the Z-axis direction, and breaking the restriction members 153 at the concave portions 153a can effectively escape the liquid container 12. In the present embodiment, the length refers to the dimension along the X-axis direction, and the thickness or the height refers to the dimension along the Z-axis direction.

The outer end of the liquid guiding portion 111 and the two ends of the limiting member 153 form a triangular arrangement and are directly connected to the outer frame 22, so that the stable assembly of the whole liquid containing device 10 in the casing 20 can be ensured, and the contact stability between the chip 14 and the electrical connection portion 52 of the printer can be improved.
