DESCRIPTION OF EMBODIMENTS

The following embodiments are illustrated with reference to the accompanied drawings, so as to illustrate the specific embodiments for implementing the present invention. The direction terms mentioned in the present invention such as “up”, “down”, “front”, “back”, “left” and “right” only refer to the directions in the accompanied drawings. Therefore, the direction terms are used for illustrating and not for limiting the present invention.

FIG. 2A is a perspective exploded view of an ink cartridge according to a first embodiment of the present invention obtained from a view angle. FIG. 2B is a perspective exploded view of the ink cartridge of FIG. 2A obtained from another view angle. Referring to FIGS. 2A and 2B, the ink cartridge 200 includes a body 210, a channel module 220, engaging parts 230a to 230d, and engaging parts 240a to 240d. In one embodiment, the body 210 is a hollow container constituted by a bottom 250 and four sidewalls substantially vertical to the bottom 250.

The body 210 has three ink chambers 212a to 212c and three ink delivery ports 216a to 216c. The ink delivery ports 216a to 216c are respectively located at a bottom 250 of the body 210, and the ink chambers 212a to 212c respectively fluidly communicate with the ink delivery ports 216a to 216c.

The channel module 220 has a chip bonding area R, three flow channels 222a to 222c, and three ink supply ports 224a to 224c. The ink supply ports 224a to 224c are located in the chip bonding area R, and the flow channels 222a to 222c respectively fluidly communicate ink delivery ports 216a to 216c with the ink supply ports 224a to 224c.

The engaging parts 230a to 230d are arranged on the body 210, for example, in the form of the four blocks or protrusions (the blocks and protrusions referred to as blocks in the present invention), and the engaging parts 240a to 240d are arranged on the channel module 220, for example, in the form of the four indentations or grooves or notches (the indentations or grooves or notches referred to as “indentations” in the present invention) as shown in FIG. 2A. The relative position of the body 210 and the channel module 220 on a two-dimension plane on the surface of the bottom 250 is substantially fixed by the engagement of the engaging parts 230a to 230d and the engaging parts 240a to 240d. The two-dimension plane is a plane extended along the x-axis and y-axis in FIGS. 2A and 2B. It should be noted that the term “fixed” in the description of “the relative position of the body and the channel module on a two-dimension plane on the surface of the bottom is substantially fixed” or the like in the embodiments of the present invention includes the meaning of locating the relative position between the channel module and the body.

Compared with the blocks 118a and 118b of the conventional ink cartridge 100 and the corresponding indentations 128a and 128b which can only restrict the channel module 120 from moving along the positive x-axis, negative x-axis, and negative y-axis relatively to the body 110, the engaging parts 230a to 230d and the engaging parts 240a to 240d of the first embodiment can restrict the channel module 220 from moving along the positive x-axis, negative x-axis, positive y-axis, and negative y-axis relatively to the body 210, and can also restrict the channel module 220 from rotating about the z-axis (orthogonal to the x-axis and y-axis) relatively to the body 210. In other words, not only a deviation of the channel module 220in x-axis and y-axis directions but also the rotation deviation about the z-axis (orthogonal to the x-axis and y-axis) can be prevented, when the channel module 220 is assembled on the body 210, by the engagement or cooperation of the engaging parts 230a to 230d and the engaging parts 240a to 240d.

Since the engaging parts 230a to 230d and the engaging parts 240a to 240d are used for locating the relative position between the channel module 220 and the body 210, the accuracy of orientation of the channel module 220 with respect to the body 210 can be improved. Therefore, when the channel module 220 is attached to the body 210, for example, by means of ultrasonic welding, the welding quality and yield can be enhanced because of the engagement of the engaging parts 230a to 230d and the engaging parts 240a to 240d. However, the method of fixing the channel module 220 onto the body 210 in the present embodiment is not limited to the ultrasonic welding, other methods such as laser welding, or bonding by adhesive can also be used to fix the channel module 220 onto the body 210. The arrangement of engaging parts in the present invention can assist to locate the channel module 220 onto the body 210. Moreover, by respectively measuring the distance between the engaging parts 230a to 230d and the distance between the engaging parts 240a to 240d, the inspector or manufacturer can easily inspect whether the channel module 220 or body 210 is manufactured within an allowable tolerance before fixing the channel module 220 onto the body 210, thereby ensuring that the channel module 220 can be correctly fitted and located on the body 210.

The engaging parts 230a to 230d are blocks, and the engaging parts 240a to 240d are indentations. However, in the embodiments which are not shown, one or all of the engaging parts 230a to 230d is/are indentation(s), and the corresponding one or all of the engaging parts 240a to 240d is/are block(s). Moreover, in one embodiment, when the engaging parts 230a to 230b are blocks and are arranged at two corners on one side of the surface of the bottom 250 (as shown for example in FIG. 2A), the engaging parts 230a to 230b can be used as positioning blocks for positioning or locating the ink cartridge 200 when the ink cartridge 200 is mounted in a printer.

The ink cartridge having three ink chambers is taken as an example. However, it is known that it is not intended to limit the number of the ink chambers of the ink cartridge of the present invention, and persons skilled in the art can determine the number of the ink chambers, for example, two ink chambers or more than four ink chambers according to the spirit of the present invention.

FIG. 3A is a perspective exploded view of an ink cartridge according to a second embodiment of the present invention obtained from a view angle. FIG. 3B is a perspective exploded view of the ink cartridge of FIG. 3A obtained from another view angle. Referring to FIGS. 3A and 3B, the ink cartridge 300 includes a body 310 and a channel module 320.

The body 310 has three ink chambers 312a to 312c and three ink delivery ports 316a to 316c. The ink delivery ports 316a to 316c are located at a bottom 350 of the body 310, and the ink chambers 312a to 312c respectively fluidly communicate with the ink delivery ports 316a to 316c.

The channel module 320 is attached to the bottom 350 of the body 310. The channel module 320 has a chip bonding area R, three flow channels 322a to 322c, and three ink supply ports 324a to 324c. The ink supply ports 324a to 324c are located in the chip bonding area R, and the flow channels 322a to 322c respectively fluidly communicate ink delivery ports 316a to 316c with the ink supply ports 324a to 324c.

The channel module 320 has a base 320a attached to the body 310, an uplift portion 320b protruding from the base 320a. The chip bonding area R is formed on the uplift portion 320b. The base 320a has a base surface B. The uplift portion 320b has a side surface S connecting the base surface B and the chip bonding area R, and the angle A between the side surface S and the base surface B is between 90 degrees and 135 degrees.

A section of the flow channel 322a substantially parallel to the abovementioned two-dimension plane extends from the chip bonding area R to an area outside the chip bonding area R. Moreover, the ink supply ports 324a to 324c are arranged in sequence. In one embodiment, the extending direction of the section of the flow channel 322a is substantially parallel to the arrangement direction of the ink supply ports 324a to 324c in the y-axis direction shown in FIGS. 3A and 3B. In another embodiment, the angle between the extending direction of the section of the flow channel 322a and the arrangement direction of the ink supply ports 324a to 324c is greater than 0 degree (i.e. the extending direction of the section of the flow channel 322a is not substantially parallel to the arrangement direction of the ink supply ports 324a to 324c). In other words, the extending direction of the section of the flow channel 322a may be designed similar to that of a section of the flow channel 322b substantially parallel to the abovementioned two-dimension plane.

In one embodiment, the ink chambers 312a to 312c are arranged in sequence, and the extending direction of the section of the flow channel 322a is substantially parallel to the arrangement direction (y-axis direction) of the ink chambers 312a to 312c. In other embodiments, the extending direction of the section of the flow channel 322a is not required to be substantially parallel to the arrangement direction of the ink chambers 312a to 312c. In other words, the extending direction of the section of the flow channel 322a can be designed similar to that of a section of the flow channel 322b substantially parallel to the abovementioned two-dimension plane. Moreover, the ink chambers 312a to 312c are arranged in sequence, and the ink supply ports 324a to 324c are arranged in sequence, and the arrangement direction of the ink chambers 312a to 312c is substantially parallel to the arrangement direction of the ink supply ports 324a to 324c (y-axis direction).

The ink chambers 312a to 312c can be arranged along different directions by horizontally extending one, some, or all of the flow channels. Therefore, compared with the ink chambers 212a to 212c in FIGS. 2A and 2B, the ink chambers 312a to 312c in FIGS. 3A and 3B can accommodate a sponge with a larger width (in the y-axis direction), such that the ink is supplied normally. It is known to persons skilled in the art that it is allowed to extend one or more flow channels instead of one flow channel as required.

FIG. 4A is a perspective exploded view of an ink cartridge according to a third embodiment of the present invention obtained from a view angle. FIG. 4B is a perspective exploded view of the ink cartridge of the present invention in FIG. 4A obtained from another view angle. The third embodiment is a combination of the first and second embodiments. The ink cartridge 400 includes a body 410, a channel module 420, engaging parts 430a to 430d, and engaging parts 440a to 440d.

The body 410 has three ink chambers 412a to 412c and three ink delivery ports 416a to 416c. The ink delivery ports 416a to 416c are respectively located at a bottom 450 of the body 410, and the ink chambers 412a to 412c respectively fluidly communicate with the ink delivery ports 416a to 416c.

The channel module 420 includes a chip bonding area R, three flow channels 422a to 422c, and three ink supply ports 424a to 424c. The ink supply ports 424a to 424c are located in the chip bonding area R, and the flow channels 422a to 422c respectively fluidly communicate ink delivery ports 416a to 416c with the ink supply ports 424a to 424c.

The channel module 420 further has a base 420a attached to the body 410 and an uplift portion 420b protruding from the base 420a. The chip bonding area R is formed on the uplift portion 420b. The base 420a has a base surface B. The uplift portion 420b has a side surface S connecting the base surface B and the chip bonding area R, and the angle A between the side surface S and the base surface B is between 90 degrees and 135 degrees.

The engaging parts 430a to 430d may be arranged on the body 410 in the form of four blocks as shown in FIG. 4A, and the engaging parts 440a to 440d may be arranged on the channel module 420 in the form of four indentations as shown in FIG. 4A. The relative position of the body 410 and the channel module 420 on a two-dimension plane is substantially fixed by the engagement of the engaging parts 430a to 430d and the engaging parts 440a to 440d. The two-dimension plane is a plane extended along the x-axis and y-axis in FIGS. 2A and 2B. By the engagement of the engaging parts 430a to 430d and the engaging parts 440a to 440d, the movement of the channel module 420 along the positive x-axis, negative x-axis, positive x-axis, and negative y-axis relatively to the body 410 can be restricted, and the rotation of the channel module 420 about the z-axis (orthogonal to the x-axis and y-axis) relatively to the body 410 can also be restricted. In other words, not only a deviation of the channel module 420 in x-axis and y-axis directions but also the rotation deviation about the z-axis (orthogonal to the x-axis and y-axis) can be prevented, when the channel module 420 is assembled onto the body 410 by the engagement or cooperation of engaging parts 430a to 430d and the engaging parts 440a to 440d.

In one embodiment, the engaging parts 430a to 430d are respectively arranged at the four corners on the surface of the bottom 450, as shown in FIG. 4A. The engaging parts 430a to 430d when arranged at two corners on the bottom 450 can provide protection for the channel module 420 fixed on the bottom 450, such that the damage to the channel module 420 or separation of the channel module 420 from the body 410, caused by the collision of the channel module 420 when the ink cartridge 400 falls onto the floor, can be avoided.

Since the engaging part 430a to 430d and the engaging parts 440a to 440d are used for locating the relative position between the channel module 420 and the body 410, the accuracy of orientation of the channel module 420 with respect to the body 410 can be improved. Therefore, when the channel module 420 is attached to the body 410, for example, by means of ultrasonic welding, the welding quality and yield can be enhanced. However, the engaging method of fixing the channel module 420 onto the body 410 in the present embodiment is not limited to the ultrasonic welding, other methods such as laser welding, or bonding by adhesive can also be used to fix the channel module 420 onto the body 410. The arrangement of engaging parts in the present invention can assist to locate the channel module 420 onto the body 410.

The engaging parts 430a to 430d are blocks, and the engaging parts 440a to 440d are indentations. However, in the embodiments which are not shown, one or all of the engaging parts 430a to 430d is/are indentation(s), and the corresponding one or all of the engaging parts 440a to 440d is/are block(s). Moreover, in one embodiment, when the engaging parts 430a to 430d are blocks and arranged at two corners on one side of the surface of the bottom 450 (as shown for example in FIG. 4A), the engaging parts 430a and 430b can be used as positioning blocks for positioning or locating the ink cartridge 400 when the ink cartridge 400 is mounted in a printer.

The section of the flow channel 422a substantially parallel to the abovementioned two-dimension plane extends from the chip bonding area R to an area outside the chip bonding area R. Moreover, the ink supply ports 424a to 424c are arranged in sequence, and the extending direction of the section of the flow channel 422a is substantially parallel to the arrangement direction of the ink supply ports 424a to 424c, i.e., in y-axis direction in FIGS. 4A and 4B.

The ink chambers 412a to 412c are arranged in sequence, and the extending direction of the section of the flow channel 422a is substantially parallel to the arrangement direction of the ink chambers 412a to 412c (y-axis direction). Moreover, the ink supply ports 424a to 424c are arranged in sequence, and the arrangement direction of the ink chambers 412a to 412c is substantially parallel to the arrangement direction of the ink supply ports 424a to 424c (y-axis direction). In other embodiments, the extending direction of the section of the flow channel 422a is not substantially parallel to the arrangement direction of the ink chambers 412a to 412c. In other words, the extending direction of the section of the flow channel 422a is designed similar to that of a section of the flow channel 422b substantially parallel to the abovementioned two-dimension plane.

The ink chambers 412a to 412c can be arranged along different directions by horizontally extending one, some, or all of the flow channels. Therefore, compared with the ink chambers 212a to 212c in FIGS. 2A and 2B, the ink chambers 412a to 412c can accommodate a sponge with a larger width (in the y-axis direction), such that the ink can be supplied normally. It is known to persons skilled in the art that it is allowed to extend one or more flow channels instead of one flow channel as required.

FIG. 5A is a schematic view of the profile of the channel module in FIG. 4A. The channel module 420 has two opposite first side edges 421a and two opposite second side edges 421b, and the four engaging parts 440a to 440d are respectively located at two ends of each of the two first side edges 421a.

When the engaging parts 540a to 540d are indentations, the engaging parts on the body (not shown) corresponding to the engaging parts 540a to 540d are blocks, and vice versa. It should be noted that the engaging parts 540c and 540d are not required to be located in the center of each of the two side edges 521a respectively, but can also be located between the center and the ends of each of the two first side edges 521a.

FIG. 5C is a schematic view of the profile of the channel module according to a fifth embodiment of the present invention. The channel module 620 has two opposite first side edges 621a, two opposite second side edges 621b. Two engaging parts 640a to 640b respectively located at an end of each of the two first side edges 621a, and another engaging part 640c located at the center of the second side edges 621b away from the abovementioned ends of the two first side edges having two engaging parts 640a to 640b respectively located at. When the engaging parts 640a to 640c are indentations, the engaging parts on the body (not shown) corresponding to the engaging parts 640a to 640c are blocks, and vice versa.

It can be known from the embodiments in FIGS. 5A to 5C that in the scope of the present invention, the number of the above engaging parts on the channel module and the body are determined according to the design requirement, and are respectively located at the corresponding position of the body and the channel module, so as to fix the relative position of the body and the channel module on the two-dimension plane. Moreover, the location of the engaging part on the channel module is not limited to any one side edge of the channel module, and can also be formed on the lower surface of the channel module attached to the bottom of the body.

FIG. 6 is a perspective exploded view of an ink cartridge according to a sixth embodiment of the present invention. Referring to FIG. 6, in the sixth embodiment, engaging parts 730a to 730d are at four corners of the external surface of the bottom 750 of the body 710 of the ink cartridge 700, and are engaged with the engaging parts 740a to 740d at four corners of the channel module 720. Compared with the ink cartridge 400 in the third embodiment of FIG. 4A, the engaging parts 730c and 730d of the ink cartridge 700 are indentations instead, and the engaging parts 740c and 740d thereof are blocks instead.
