As shown in fig. 1 to 3, the conventional inkjet printing apparatus includes a carriage 91, at least one cartridge mounting chamber 911 is provided on the carriage 91, an opening of the cartridge mounting chamber 911 is located at the top of the cartridge 92 in the height direction Z2 of the cartridge 92, and an interface is provided at the bottom of the cartridge mounting chamber 911. The ink cartridge mounting chamber 911 is provided with a connection terminal 912 and a mating portion 9111, the body of the connection terminal 912 is provided with a plurality of accommodating grooves 9121, the plurality of accommodating grooves 9121 are distributed along the width direction Y2 of the ink cartridge 92, and each accommodating groove 9121 is provided with a conductive pin 9122. In the longitudinal direction X2 of the ink cartridge 92, the connection terminal 912 and the mating portion 9111 are both located on the first side of the ink cartridge 92, and the conductive pin 9122 has the elastic contact portion 91221 thereon, and the elastic contact portion 91221 extends toward the first side wall of the ink cartridge 92 in the longitudinal direction X2 of the ink cartridge 92 and protrudes to the accommodating groove 9121.

The conventional ink cartridge 92 generally includes a cartridge body and a chip 922, wherein a handle 9211 is formed on a first side wall of the cartridge body in a length direction X2 of the ink cartridge 92, and a fastening portion 9211 is formed on the handle 9211; chip 922 is mounted on the first side wall, and chip 922 is provided with electrical contacts 9221 and memory 9222 for storing information of ink cartridge 92; in the height direction Z2 of the ink cartridge 92, an ink outlet 9212 is provided at the bottom of the ink cartridge 92. When the ink box 92 is mounted in the ink box mounting cavity 911 in the height direction Z2 of the ink box, the buckling part 9211 on the handle 9211 is matched and connected with the matching part 9111 in the ink box mounting cavity 911 to limit the movement of the ink box 92 in the height direction Z2, and the ink outlet 9212 is in butt joint with the interface at the bottom of the ink box mounting cavity 911, so that the ink in the ink box 92 can flow to a printing nozzle arranged on the carriage 91 through the interface; meanwhile, the elastic contact portions 91221 on the connection terminals 912 are electrically connected to the matching electrical contact points 9221 on the chip 922, so that the inkjet printing apparatus can read the relevant information in the memory 9222 stored on the chip 922 to know the remaining ink amount of the ink cartridge 92, whether the mounted state of the ink cartridge 92 is correct, and the like. However, the existing ink cartridges 92 suffer from the following drawbacks:

to ensure that a stable electrical connection can be made between the elastic contact portion 91221 of the conductive pin 9122 on the connection terminal 912 and the electrical contact point 9221 on the chip 922, the protruding amount of the elastic contact portion 91221 extending toward the electrical contact point 9221 in the length direction X2 is generally increased, so that the elastic contact portion 91221 has a certain interference with respect to the chip 922 in the length direction X2 of the ink cartridge 92, thereby improving the pressing force of the elastic contact portion 91221 on the electrical contact point 9221 on the chip 922 when the ink cartridge 92 is mounted in the cartridge mounting cavity 911, and improving the stability of the electrical connection between the elastic contact portion 91221 and the electrical contact point 9221; although this method of handling increases the stability of the electrical connection between the spring contact portion 91221 and the electrical contact point 9221, it also makes the ink cartridge 92 more difficult to mount and dismount due to the greater pressing force and obstruction from the spring contact portion 91221 during the mounting process, and increases the risk of the spring contact portion 91221 scraping the electrical contact point 9221 of the chip 922. Further, since the handle 9211 provided on the ink tank 92 only serves to restrict the movement of the ink tank 92 in the height direction Z2, if the degree of protrusion of the elastic contact portion 91221 in the longitudinal direction X2 toward the electrical contact point 9221 is reduced to reduce the difficulty in attaching and detaching the ink tank 92 and the risk of scraping the electrical contact point 9221 of the chip 922, the stability of the electrical connection between the elastic contact portion 91221 and the electrical contact point 9221 may be deteriorated due to the influence of vibration of the ink tank 92 during the movement of the carriage 91.

Of course, as an alternative, the second rotating shaft 322 may be formed at the first end of the swing handle 31, and accordingly, the connecting portion 311 is formed on the box 32. Further, similarly to the first embodiment, the second end of the swing handle 31 is formed with an operation portion 312, and the operation portion 312 is located above the box 32 in the height direction of the box 32.

The swing handle 31 is provided with a buckling part 313, a chip mounting position 314 and a limiting rib 315, and the buckling part 313 is positioned on one surface of the swing handle 31, which is opposite to the first side wall 321 of the box body 32, and extends out of the first side wall 321; the chip 33 is mounted in the chip mounting position 314, and the function and the setting manner of the limit rib 315 are the same as those of the first embodiment of the printing apparatus, so that repeated description is omitted here.

A second elastic member 30 is disposed between the swing handle 31 and the box 32, and the second elastic member 30 is used for forcing the swing handle 31 to rotate away from the first sidewall 321 of the box 32, so that the swing handle 31 can rotate to the matching position. Preferably, in the present embodiment, the second elastic member 30 is a spring, and the spring is formed on a surface of the swing handle 31 facing the first side wall 321, and the spring extends from the swing handle 31 to the bottom of the box body 32 and toward the first side wall 321, so that the spring can cooperate with the first side wall 321 to force the swing handle 31 to rotate away from the first side wall 321, and the second elastic member 30 is configured as a spring, so that the assembly of the ink cartridge can be simplified and the production cost can be reduced. Of course, as an alternative, the second elastic member 30 may also be a compression spring, where the connection manner between the compression spring and the box 32 and the swing handle 31 may refer to the connection manner between the first elastic member and the box 32 and the moving handle when the first elastic member in the first embodiment of the printing apparatus is a compression spring, so that the description is not repeated here; in addition, based on the above, it is also clear that the type, connection manner, etc. of the second elastic member 30 can be adaptively changed and designed on the premise of ensuring that the second elastic member 30 realizes the rotation of the swing handle 31 against the first side wall 321 of the box body 32.

Preferably, the side of the swing handle 31 facing the first side wall 321 is further provided with a limiting protrusion 316, the first height of the limiting protrusion 316 protruding from the swing handle 31 is smaller than the second height of the elastic sheet protruding from the swing handle 31, and the limiting protrusion 316 can protect the elastic sheet and prevent the swing handle 31 from being excessively rotated toward the box 32 to be extruded to be broken.

Further, the first side of the case 32 has a chute portion 323, and the chute portion 323 extends along the rotation direction of the swing handle 31; accordingly, the swing handle 31 has a pin portion 317 thereon, and the pin portion 317 is slidably mounted in the slide groove portion 323 in the rotational direction. This design can play a limiting role on the rotation of the swing handle 31 and make the installation of the ink cartridge more convenient.

Of course, in this process, the swing handle 31 may be held only at a position between the disengaged position and the engaged position without being rotated completely to the disengaged position, on the premise that the ink cartridge can be smoothly mounted into the cartridge accommodating chamber.

Next, the ink cartridge is correctly mounted in the ink cartridge mounting cavity, and then the swing handle 31 is released, so that the swing handle 31 rotates back to the first side wall 321 under the action of the elastic force of the elastic piece until the swing handle 31 rotates to the matching position (as shown in fig. 11 and 12). In the process of rotating the swing handle 31 from the disengaging position to the matching position, the buckling part 313 of the swing handle 31 gradually moves to the matching part on the end wall of the ink box accommodating cavity, and the limit rib 315 of the swing handle 31 is gradually inserted into the clamping groove between the ink box accommodating cavity and the connecting terminal 34; and the chip 33 is moved along with the swing handle 31 so that the electric contact pins 331 thereon are gradually inserted into the corresponding receiving grooves 341 on the connection terminals 34.

When the swing handle 31 rotates to the fitting position, the buckling part 313 of the swing handle 31 completes the snap connection with the fitting part on the end wall of the cartridge accommodating chamber to restrict the movement of the ink cartridge in the height direction and the length direction; the limit rib 315 of the swing handle 31 is inserted into the clamping groove between the ink cartridge accommodating cavity and the connecting terminal 34 to limit the movement of the ink cartridge in the width direction; the electrical contact pins 331 of the chip 33 are inserted into the corresponding receiving grooves 341 on the connection terminals 34 and are contacted with the conductive pins 342 in the receiving grooves 341, so that electrical connection between the electrical contact pins 331 and the conductive pins 342 is realized, and communication between the chip 33 and the printing device is established; meanwhile, the elastic sheet enables the swinging handle 31 to be kept at the matching position through the elastic force of the elastic sheet, so that the stability and the reliability of the operation of the ink box and the printing equipment are ensured.

When the ink cartridge is required to be taken out of the ink cartridge accommodating chamber, the operation part 312 is pressed to rotate the swing handle 31 to the first side wall 321, and the elastic sheet is extruded and deformed until the swing handle 31 rotates to the disengaging position, so that the buckling part 313 of the swing handle 31 is released from the buckling connection with the matching part on the end wall of the cartridge accommodating chamber, the limit rib 315 of the swing handle 31 is released from the connection with the clamping groove, the electric contact pin 331 of the chip 33 is released from the electric connection with the conductive needle 342 and exits the accommodating groove 341, and then the ink cartridge is taken out of the ink cartridge accommodating chamber; of course, in this process, the swing handle 31 may be held only at a position between the disengaged position and the engaged position without being rotated completely to the disengaged position, on the premise that the ink cartridge can be smoothly mounted into the cartridge accommodating chamber.

Finally, it should be emphasized that the foregoing description is merely illustrative of the preferred embodiments of the utility model, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the utility model, and any such modifications, equivalents, improvements, etc. are intended to be included within the scope of the utility model.
