detailed description

Unless otherwise stated, the directional terms such as "up, down, left, right" and "front and back" in the present invention are relative to the directions shown in the drawings. In order to clearly describe the relative positional relationship between the ink cartridges and the various components on the ink cart, the X, Y, and Z axis concepts are cited. Taking the three-dimensional structure of the ink cartridge as a reference, the directions of the three axes respectively represent the "length direction" and "width direction of the ink cartridge. "," Height direction ", that is, when the ink cartridge is installed into the ink cart according to the usage orientation, the direction along the ink cartridge from the front engagement protrusion to the rear engagement protrusion is the" length direction ", or the X axis direction, along the The direction in which the ink cartridges are arranged in the ink cart is the “width direction”, or the Y-axis direction, and the direction from the bottom surface to the top surface of the ink cartridge is the “height direction”, or the Z-axis direction. The X, Y, and Z axes are three spatial axes orthogonal to each other.

As shown in FIGS. 1 to 7, a printer according to a preferred embodiment of the present invention includes an ink cart 1 and an ink cartridge 2 detachably mounted on the ink cart 1. The ink cart 1 is an assembly part configured for the printer. The original ink cartridge or the new ink cartridge is installed on the ink cart 1 and maintains stable and reliable contact and positioning with the ink cart 1.

The ink cart 1 to which the handle-type ink cartridge of the present invention is fitted includes a body having a handle bracket 10 for rotating the rotating handle 3 of the ink cart 1. When the ink cart 1 is used with the original ink cartridge, the ink cartridge itself is no longer equipped with a handle, but is fixed by rotating the rotating handle 3 provided on the handle bracket 10 to increase the ink storage capacity of the original ink cartridge as much as possible. The body of the ink cart 1 also has a chip contact area 11 for setting a chip ejector. Referring to FIG. 2, the lower end of the handle bracket 10 and the chip contact area 11 are spaced up and down, and the lower end of the handle bracket 10 is formed with a first engaging surface 100 that is inclined. In the direction away from the installation position of the ink cartridge on the ink cart 1, that is, along the positive X-axis direction in FIG. 2, the first engaging surface 100 is inclined from high to low.

Referring to FIG. 1, an engagement hole 12 is formed on the side of the body of the ink cart 1 opposite to the installation position of the rotary handle 3. It can be understood that the body of the ink cart 1 referred to herein refers to the portion of the ink cart 1 except for the movable parts such as the rotating handle 3.

Referring to the perspective view of the rotating handle 3 shown in FIG. 3, the rotating handle 3 has a rotating shaft 31 that is rotatably mounted on the ink cart 1 to enable the rotating handle 3 to rotate relative to the handle bracket 10. The rotating handle 3 is also provided with a pair of guide ribs 30 parallel to each other. A pair of parallel planes facing each other of the pair of guide ribs 30 is a guide side 300. The guide side 300 is used to guide the installation and insertion process of the ink cartridge 2.

Referring to FIGS. 4 to 7, the ink cartridge 2 includes an ink cartridge body 20 and a handle 21 provided on the ink cartridge body 20. The handle 21 is provided with a front engagement protrusion 22 that can extend below the lower end of the handle bracket 10 . The front engagement projection 22 has a second engagement surface 220, and the second engagement surface 220 is formed by the height of the front engagement projection 22 on the handle 21, that is, the positive X-axis direction in FIG. When the front engaging protrusion 22 extends below the lower end of the handle bracket 10, the second engaging surface 220 and the first engaging surface 100 form a relatively stable positioning relationship such as surface contact or line contact. The ink cartridge 2 is locked into the ink cart 1. It can be understood that the first engaging surface 100 and the second engaging surface 220 preferably have the same inclination. Preferably, the inclination angle of the second engaging surface 220 is set according to the first engaging surface 100, that is, according to the ink The structure of the vehicle 1 sets the corresponding cooperation structure of the ink cartridge 2.

1 and 7, the ink cartridge body 20 is provided with a rear engagement protrusion 23 at a position corresponding to the engagement hole 12 of the ink cart 1. When the ink cartridge 2 is installed in the ink cart 1, the rear engagement The protrusion 23 snaps into the engaging hole 12. The front engaging protrusion 22 and the rear engaging protrusion 23 are preferably arranged at the same horizontal height, that is, when the first engaging surface 100 and the second engaging surface 220 are in surface contact, the force against the two The component force in the horizontal direction is approximately the same level as the direction in which the rear engaging protrusion 23 is engaged with the engaging hole 12. In this way, the relative position of the ink cartridge 2 and the ink cart 1 is more stable, and the displacement of the ink cartridge 2 relative to the ink cart 1 is avoided.

On the ink cart 1, the handle brackets 10 are arranged at intervals, and each rotating handle 3 is rotatably installed between two adjacent handle brackets 10. Referring to FIG. 6, along the width direction of the ink cartridge 2, that is, the Y-axis direction, two front engagement protrusions 22 may be provided on the handle 21 at intervals. Along the Y-axis direction, the distance between the inner sides of the two front engaging protrusions 22 is defined as W. Referring to FIG. 3, in the same direction, the distance between the side surfaces 32 on which the two sections of the rotating shaft 31 of the rotating handle 3 are located is defined as D. The following relationship is satisfied between W and D: W≥D, so that the two front engaging protrusions 22 can be engaged with the ink cart 1 at positions other than the two side faces 32, so as to ensure that the rotary handle 21 is smoothly engaged to the ink cart The predetermined snap position within 1.

In consideration of practical application, the width of the front engaging protrusion 22 is preferably not more than 1.5 mm along the Y-axis direction. This is because the remaining gap between the rotary handle 3 and the handle bracket 10 is relatively narrow, and the width of the front engagement protrusion 22 exceeding 1.5 mm may prevent the rotary handle 21 from sliding down to a predetermined engagement position in the ink cart 1.

Further, the handle 21 and the ink cartridge body 20 are preferably detachably connected and made of different materials, wherein: the ink cartridge body 20 is made of PP or PS material capable of ultrasonic welding to meet the ultrasonic welding seal after ink injection The handle 21 is made of PC material with better hardness and toughness, ABS material, nylon or modified materials containing the above materials to avoid wear failure of the front engagement protrusion 22 after multiple engagements. The hardness and toughness of PC, ABS, nylon and modified materials containing these materials are superior to the PP material or PS material of the ink cartridge body 20. However, the handle 21 is different from the ink cartridge body 20, and there is no need for ultrasonic welding. Therefore, using these materials can satisfy the basic functions of the handle 21 while also increasing the durability and elasticity of the handle 21. Moreover, due to the irregular shape of the handle 21, the detachable connection between the handle 21 and the ink cartridge body 20 is made, and the two parts can be transported separately when the ink cartridge 2 is transported to avoid damage to the handle 21.

The handle 21 specifically includes an elastic operation board 210, a chip mounting board 211, and an ink cartridge mounting board 212, and the three parts are fixed to each other or provided integrally. The front engaging protrusion 22 is provided on the elastic operation board 210, and in order to enable the ink cartridge 2 to be installed in the ink cart 1, the elastic operation board 210 needs to be able to generate a certain deformation so that the front engaging protrusion 22 can extend into Or withdraw the lower end of the handle bracket 10 on the ink cart 1. The elastic operation board 210 preferably extends in an arc shape or is connected to the chip mounting board 211 at an obtuse angle, and the front engagement protrusion 22 is preferably provided at a position where the elastic operation board 210 can be greatly deformed. When the ink cartridge 2 is removed, the elastic operating plate 210 is driven to undergo a certain amount of elastic deformation, so that the front engaging protrusion 22 is pulled out of the lower end of the handle bracket 10. Since the front engaging protrusion 22 is disposed at a position where the elastic operation panel 210 is greatly deformed, the front engaging protrusion 22 can be largely displaced along with the elastic deformation of the elastic operation panel 210, which facilitates the removal of the ink cartridge 2. In addition, in order to ensure reliable contact between the chip on the ink cartridge 2 and the chip ejector on the chip contact area 11 of the ink cart 1, the front engaging protrusion 22 is disposed as close to the chip mounting plate 211 as possible.

The chip mounting plate 211 faces the chip contact area 11 for mounting the chip 4 of the ink cartridge 2. The chip mounting plate 211 and the ink cartridge mounting plate 212 respectively abut on different sides of the ink cartridge body 20, and respectively define the vertical and horizontal movements between the ink cartridge body 20 and the handle 21, so that the ink cartridge body 20 and the handle 21 has a reliable positioning relationship. In some embodiments, as shown in FIG. 4, the chip mounting plate 211 has a hook 2110 attached to the surface of the ink cartridge body 20. A corresponding position of the ink cartridge body 20 is provided with a hook hole 200 that can accommodate the hook 2110.

Referring to FIGS. 4 and 5, the ink cartridge mounting plate 212 is provided with a hanging hole 2120 on the surface of the ink cartridge body 20. The corresponding position of the ink cartridge body 20 is provided with a hanging protrusion 201 that can be inserted into the hanging hole 2120. Along the width direction of the ink cartridge body 20, that is, the Y-axis direction shown in the figure, there are two hanging protrusions 201 and hanging holes 2120, which are arranged at intervals. Further, one of the ink cartridge body 20 and the ink cartridge mounting plate 212 is provided with a positioning rib 2121 extending along the height direction of the ink cartridge body (that is, along the Z-axis direction as shown), and the other is provided with a positioning rib 2121 capable of accommodating the positioning The positioning groove 202 of the rib 2121.

Through the above arrangement, the hook 2110 and the hook hole 200 jointly define the displacement of the ink cartridge body 20 relative to the handle 21 in the ink cartridge height direction, so that a positioning relationship along the Z-axis direction is formed between the ink cartridge body 20 and the handle 21; The cooperation between the starter 201 and the hanging hole 2120, and the positioning rib 2121 and the positioning groove 202 define the relative displacement between the ink cartridge mounting plate 212 and the ink cartridge body 20, so that the X axis is formed between the ink cartridge body 20 and the handle 21 Positioning relationship with the Y-axis direction.

Referring to FIGS. 3, 4, and 6, the elastic operating plate 210 of the handle 21 is further provided with a guide portion 24. The guide portion 24 has at least one guide fitting surface 240. The guide fitting surface 240 and the rotating handle 3 The guide sides 300 are parallel to each other and cooperate with each other. In this way, when the ink cartridge 2 is installed in the ink cart 1, the guide fitting surface 240 of the guide portion 24 is guided by the guide side face 300 of the rotary handle 3, and the process of guiding the ink cartridge 2 into the ink cart 1 is restricted, limiting the ink cartridge 2 to the Y axis The position in the direction.

Preferably, the guide portion 24 may include two guide fitting surfaces 240 that are opposite and parallel to each other. The distance between the pair of mutually parallel guide fitting surfaces 240 in the Y direction is slightly smaller than the distance between the two guide side surfaces 300 on the rotary handle 3, so that the guide portion 24 can be on the pair of guide side surfaces 300 The position in the Y-axis direction when the ink cartridge 2 is engaged with the ink cartridge 2 and the ink cartridge 1 is engaged with each other.

The guide portion 24 may be integrally formed with the front engaging protrusion 22, or the two may be independent of each other.
