[0051] like Figures 1 to 9 As shown, this embodiment provides a liquid box, which can be an ink box, suitable for use in a printer to provide ink for the printer to print. By optimizing the internal chamber structure of the liquid box, the volume ratio and ink storage capacity of the internal liquid box are improved.

[0052] In the present embodiment, the liquid box includes a box body 100, and the interior of the box body 100 is provided with a front chamber 110 and a rear chamber 120 at intervals along the front-to-back direction, and a first chamber 130 and a second chamber 140 are arranged side by side along the left-to-right direction between the front chamber 110 and the rear chamber 120, the front chamber 110 is communicated with the first chamber 130, and the rear chamber 120 is communicated with the second chamber 140, an ink passage 150 is provided between the first chamber 130 and the second chamber 140, the front chamber 110 and the rear chamber 120 are communicated with each other through the ink passage 150, an air inlet chamber 160 is partially formed in the rear chamber 120, and the first chamber 130 and the second chamber 140 are both communicated with the air inlet chamber 160, and the box body 100 is provided with an air inlet hole 161 connected to the air inlet chamber 160, and the air inlet hole 161 is communicated with the first ink outlet 131 of the first chamber 130 and the second ink outlet 141 of the second chamber 140. Specifically, the gas flows from the air inlet hole 161 to the air inlet chamber 160, and a part of the gas can enter the first chamber 130 so that the ink in the first chamber 130 can flow out normally from the first ink outlet 131; the other part can enter the second chamber 140 so that the ink in the second chamber 140 can flow out normally from the second ink outlet 141, that is, the air pressure balance in the liquid box can be maintained.

[0053] The first chamber 130 is located on the right side of the second chamber 140. In other embodiments, the first chamber 130 may also be located on the left side of the second chamber 140. For ease of description, the first chamber 130 is located on the right side of the second chamber 140 for description.

[0054] In the present embodiment, all other space in the rear chamber 120 except the air inlet chamber 160 can be used for storing ink, which greatly improves the volume ratio and ink storage capacity of the liquid box compared with the ink cartridge in the prior art; at the same time, the front chamber 110 is connected to the first chamber 130, and the rear chamber 120 is connected to the second chamber 140, which is conducive to the ink in the front chamber 110 flowing into the first chamber 130, and the ink in the rear chamber 120 flowing into the second chamber 140, and each flow path is shortened, thereby improving the smoothness of the ink flow and avoiding the problem of printing line breakage.

[0055] Combination Figure 3 As shown, in some embodiments, a connecting groove 170 is provided on the top of the box body 100, and the liquid box includes a sealing member, which is not shown in the figure. The sealing member cover is provided on the connecting groove 170 and forms a transfer channel. The box body 100 is provided with a first connecting hole 171 connecting the transfer channel and the air inlet chamber 160, a second connecting hole 172 connecting the transfer channel and the first chamber 130, and a third connecting hole 173 connecting the transfer channel and the second chamber 140.

[0056] Combination Figure 4As shown, the box body 100 includes a bottom box 1001 and a top cover 1002 covered on the bottom box 1001, wherein the communication groove 170 is provided on the top cover 1002.

The third communication hole 173 is provided at the second end of the communication transverse groove 1702. The first communication hole 171 is provided at the second end of the communication longitudinal groove 1701. In this embodiment, the communication longitudinal groove 1701 extends in the front-to-back direction. The first communication hole 171 is located directly behind the second communication hole 172.

[0058] With the setting of the above-mentioned path, even if the liquid tilts and causes ink to leak out of the second chamber 140 through the third connecting hole 173, the flowing ink will preferentially enter the first chamber 130 through the second connecting hole 172 to be reused, thereby improving the effect of preventing ink leakage.

[0059] In other embodiments, on the basis that the first connecting hole 171 is connected to the air inlet chamber 160, the second connecting hole 172 is connected to the first chamber 130, and the third connecting hole 173 is connected to the second chamber 140, other layout modes may be provided regarding the positional relationship between the connecting longitudinal groove 1701 and the connecting transverse groove 1702. Exemplarily, the connecting longitudinal groove 1701 is arranged obliquely, that is, the first end of the connecting longitudinal groove 1701 is connected to the second end of the connecting transverse groove 1702, the second connecting hole 172 is arranged at the first end of the connecting transverse groove 1702, and the third connecting hole 173 is arranged at the second end of the connecting transverse groove 1702; the first connecting hole 171 is arranged at the second end of the connecting longitudinal groove 1701.

[0060] In another exemplary embodiment, the communication longitudinal groove 1701 extends in the front-to-back direction, that is, the first end of the communication longitudinal groove 1701 is connected to the second end of the communication transverse groove 1702, the second communication hole 172 is provided at the first end of the communication transverse groove 1702, the third communication hole 173 is provided at the second end of the communication transverse groove 1702; and the first communication hole 171 is provided at the second end of the communication longitudinal groove 1701. The first communication hole 171 is located directly behind the third communication hole 173.

[0061] In another exemplary embodiment, the communication longitudinal groove 1701 is arranged obliquely, that is, the first end of the communication longitudinal groove 1701 is connected to the first end of the communication transverse groove 1702, the second communication hole 172 is arranged at the first end of the communication transverse groove 1702, the third communication hole 173 is arranged at the second end of the communication transverse groove 1702; the first communication hole 171 is arranged at the second end of the communication longitudinal groove 1701. The first communication hole 171 is located directly behind the third communication hole 173.

[0062] In some embodiments, the diameter of the second communication hole 172 and the diameter of the third communication hole 173 are both greater than the diameter of the first communication hole 171. In some embodiments, the diameter of the second communication hole 172 and the diameter of the third communication hole 173 are the same.

[0063] Recombination Figure 1 As shown, the box body 100 has a first partition wall 106, and the first partition wall 106 and the right side wall 104 of the box body 100 form a first chamber 130, and the first partition wall 106 is provided with a first hole 1061 connecting the front chamber 110 and the first chamber 130; the box body 100 has a second partition wall 107, and the second partition wall 107 and the left side wall 103 of the box body 100 form a second chamber 140, and the second partition wall 107 is provided with a second hole 1071 connecting the rear chamber 120 and the second chamber 140. The arrangement of the above-mentioned structure reasonably utilizes the structure of the box body 100, reduces the materials used to surround the first chamber 130 and the second chamber 140, and reduces costs; at the same time, the arrangement of the first partition wall 106 and the second partition wall 107 can also play a supporting role, which helps to improve the structural strength of the box body; in addition, the front chamber 110 and the first chamber 130 are connected through the first hole 1061, and the rear chamber 120 and the second chamber 140 are connected through the second hole 1071. The front chamber 110 can preferentially supply ink to the first chamber 130, and the rear chamber 120 can preferentially supply ink to the second chamber 140. The ink supply path is optimized, which is beneficial to improving the stability of the ink supply.

[0064] In some embodiments, the air inlet chamber 160 is located behind the first chamber 130, and the air inlet chamber 160 and the second chamber 140 are staggered in the front-to-back direction. The air inlet chamber 160 and the second hole 1071 are staggered in the front-to-back direction so that the ink in the rear chamber 120 flows more smoothly into the second chamber 140. The air inlet chamber 160 is located in the rear chamber 120 and is closer to the right side wall 104 of the liquid box.

[0065] Furthermore, the air inlet chamber 160 is staggered with the ink passage 150 in the front-to-back direction, so that the ink in the front chamber 110 and the rear chamber 120 can also flow smoothly through the ink passage 150 more easily.

[0066] In some embodiments, the air inlet chamber 160 is located behind the second chamber 140, and the air inlet chamber 160 and the first chamber 130 are staggered in the front-to-back direction.

[0067] In some embodiments, the distance between the air inlet hole 161 and the first hole 1061 is greater than the distance between the air inlet chamber 160 and the second hole 1071 .

[0068] The first hole 1061 includes a first communicating portion 1062 and a second communicating portion 1063 which are connected. The first communicating portion 1062 is located on the upper side of the second communicating portion 1063. In the left-right direction, the width of the first communicating portion 1062 is smaller than the width of the second communicating portion 1063. The width of the upper communicating hole is small, which helps to improve the structural strength; the width of the lower communicating hole is large, which helps to improve the connection effect.

[0069] The box body 100 has an air intake partition wall 105 inside, and the air intake partition wall 105 and the rear side wall 102 of the box body 100 form an air intake chamber 160. The above-mentioned structure reasonably utilizes the structure of the box body 100, reduces the material used to surround the air intake chamber 160, and reduces the cost; at the same time, the setting of the air intake partition wall 105 can also play a supporting role, which helps to improve the structural strength of the box body.

With the arrangement of the above structure, the front and rear side walls of the limiting groove 310 can be used as limiting surfaces to limit the displacement of the liquid box in the front and rear directions; at the same time, the structure of the groove is simple, which is convenient for production and processing, and reduces the cost of the liquid box.

[0075] Combination Figure 5 As shown, in this embodiment, the limiting portion 300 includes a front limiting wall 311 and a rear limiting wall 312, and the front limiting wall 311 and the rear limiting wall 312 are spaced apart in the front-to-back direction, and the left and right sides of the rear limiting wall 312 protrude forward respectively and form a left limiting wall 313 and a right limiting wall 314, and there is a gap 315 between the left limiting wall 313 and the right limiting wall 314 and the front limiting wall 311, and the front limiting wall 311, the rear limiting wall 312, the left limiting wall 313 and the right limiting wall 314 are arranged to form a limiting groove 310. With the aid of this arrangement, on the one hand, the provision of the gap 315 makes the limiting groove 310 not completely closed in the left-right direction, which is convenient for injection molding; on the other hand, the provision of the gap 315 can also help save materials and reduce the processing cost of the limiting portion 300; on the third hand, with the aid of the provision of the left limiting wall 313 and the right limiting wall 314, the limiting portion 300 can also cooperate with the carriage 1000 and limit the displacement of the box body 100 in the left-right direction; on the fourth hand, with the aid of the provision of the left limiting wall 313 and the right limiting wall 314, the rear limiting wall 312 can also be reinforced.

[0076] In some embodiments, the width of the upper end of the gap 315 is smaller than the width of the lower end. In other words, the gap 315 is a flared structure, and its width gradually increases from top to bottom. This arrangement makes the connection between the rear limiting wall 312 and the replacement part 1003 more stable; at the same time, it helps to reduce the material used for the left limiting wall 313 and the right limiting wall 314, thereby reducing costs; finally, the width of the gap 315 limits the front side of the left limiting wall 313 and the right limiting wall 314 to an inclined structure, which is conducive to injection molding.

[0077] A slope 3121 is provided on the side of the lower end of the rear limiting wall 312 close to the front limiting wall 311, and the width from the lower end of the slope 3121 to the front limiting wall 311 is greater than the width of the lower end of the gap 315. This arrangement allows the slope 3121 to play a guiding role when the liquid box is installed on the carriage 1000, making it easier to insert the limiting protrusion 1100 into the limiting groove 310, thereby improving the convenience of installing the liquid box on the carriage 1000. Further, a sharp angle structure is provided at the upper end of the limiting protrusion 1100. In other words, two guide surfaces are provided at the upper end of the limiting protrusion 1100, and the two guide surfaces are close to each other in an upward direction. With the help of the above-mentioned sharp angle setting, the limiting protrusion 1100 plays a guiding role when it is inserted into the limiting groove 310, thereby further improving the convenience of installing the liquid box on the carriage 1000.

[0078] Combination Figure 8 , Fig. 9 and Fig.10 As shown, in order to achieve the limitation of the liquid box relative to the carriage 1000 in the front and rear directions, other structures can also be used. In some embodiments, the limiting portion 300 includes a front protrusion 320 provided on the front side wall 101 of the box body 100 and a reinforcing rib 330 provided on the rear side wall 102 of the box body 100, and the front protrusion 320 and the reinforcing rib 330 are sandwiched between the front stopper 1200 and the rear stopper 1300 of the carriage 1000. The above arrangement enables the reinforcing rib 330 to play a role in reinforcing the rear side wall 102 of the liquid box on the one hand; on the other hand, it can also serve as a limiting structure of the liquid box in the front and rear directions.

[0079] In some embodiments, the reinforcing rib 330 is in a rectangular parallelepiped shape, and the length and height of the reinforcing rib 330 are greater than the thickness. The length of the reinforcing rib 330 is the dimension of the reinforcing rib 330 in the front-to-back direction, the height of the reinforcing rib 330 is the dimension of the reinforcing rib 330 in the up-down direction, and the thickness of the reinforcing rib 330 is the dimension of the reinforcing rib 330 in the left-right direction.

[0080] In order to improve the supporting effect of the reinforcing ribs 330 on the rear side wall 102, in some embodiments, the number of reinforcing ribs 330 is set to be several, and the several reinforcing ribs 330 are arranged at intervals along the left-right direction. An accommodation space is formed between two adjacent reinforcing ribs 330 to accommodate excess ink flowing out of the first ink outlet 131 and / or the second ink outlet 141.

[0081] In addition, since the limiting groove 310 is eliminated, the probability of collision between the liquid box and the carriage 1000 when the liquid box is installed on the carriage 1000 is reduced, and the probability of damage to the structure surrounding the limiting groove 310 and the upper limit protrusion 1100 on the carriage 1000 and other structures corresponding to the limiting groove 310 due to collision is reduced.

[0082] In some embodiments, the liquid box has only one ink storage chamber or has three or five ink storage chambers, and the connection structure provided on the carriage 1000 outside the liquid box can ensure the relative position stability between the liquid box and the carriage 1000. In other words, the connection structure between the liquid box and the carriage 1000 is only related to the relevant structure outside the liquid box, and has no direct relationship with the chamber structure inside the liquid box. Therefore, in some embodiments, the chamber structures inside the liquid box are not limited.

[0083] Exemplarily, the liquid box includes a box body 100, the front side wall 101 of the box body 100 is connected with a locking mechanism 1011 and a limiting portion 300, and the rear side wall 102 of the box body 100 is provided with a limiting block 1021, the locking mechanism 1011 and the limiting block 1021 are used to cooperate with the carriage 1000 and limit the movement of the box body 100 in the up and down directions; the limiting portion 300 is used to cooperate with the carriage 1000 and limit the movement of the box body 100 in the front and back directions.

[0084] It is worth noting that the specific structure of the locking mechanism 1011 and the limiting portion 300 cooperating with the carriage 1000 to limit the movement of the box body 100 in the up and down directions can adopt a structure well known to those skilled in the art, which is not the main content to be protected in this application, so it will not be elaborated here.

[0085] In this embodiment, the front side wall 101 of the box body 100 is connected to the replacement part 1003, and at least one of the engaging mechanism 1011 and the limiting part 300 is arranged on the replacement part 1003. The specific positional relationship between the engaging mechanism 1011 and the limiting part 300 can be set with reference to the above embodiment, and will not be repeated here.

[0086] Combination Fig.11 and Fig.12As shown, in the present embodiment, a front chamber 110 and a rear chamber 120 are provided inside the box body 100 at intervals along the front-to-back direction, a first chamber 130 is provided between the front chamber 110 and the rear chamber 120; the rear chamber 120 is communicated with the first chamber 130, an ink passage 150 is provided between the first chamber 130 and the inner side wall of the box body 100, the front chamber 110 and the rear chamber 120 are communicated with each other through the ink passage 150, an air inlet chamber 160 is partially formed in the rear chamber 120, the first chamber 130 is communicated with the air inlet chamber 160, the box body 100 is provided with an air inlet hole 161 connected to the air inlet chamber 160, and the air inlet hole 161 is communicated with the first ink outlet 131 of the first chamber 130.

[0087] In other embodiments, the structure in which the rear chamber 120 is connected to the first chamber 130 may be replaced by the structure in which the front chamber 110 is connected to the first chamber 130. As long as the ink in the front chamber 110 and the rear chamber 120 can enter the first chamber 130, it is sufficient.

[0088] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
