Abstract
Description
Technical Field
[0001] This utility model relates to a printing material box. Background Technology
[0002] In the prior art, there is a printed material box that is detachably installed on the mounting part of a liquid spraying device. A circuit board is disposed on the shell of the box, and a thin sheet-like cover component is attached to the surface of the shell.
[0003] Because a circuit board is mounted on the casing of the box, it is not easy to remove the circuit board when reusing the box after use. Therefore, it is not easy to reuse the box.
[0004] To address the aforementioned issues, Chinese patent document CN117984665A discloses a printing material box and a printing system. The printing material box has an identification part for recording identification information, and the printing device has a box mounting part. During the process of installing the printing material box onto the box mounting part, the identification part is located in a position where it can be optically read by the reading part.
[0005] However, in the prior art described above, in order to facilitate the reading of the identification information recorded by the identification unit by the reading unit, the identification unit on the printed material box is exposed to the outside, which makes the identification unit very easy to get dirty and damaged during production, transportation or use; at the same time, there is also a risk that the identification unit is easily counterfeited because it is exposed to the outside.
[0006] In addition, existing technologies also use flexible bags to hold printing materials such as ink. During production, the ink needs to be injected into the flexible bag first, and then the bag is fixed inside the printing material box, which is a drawback of being more cumbersome to produce. Utility Model Content
[0007] To at least partially address the shortcomings of the prior art, this utility model provides a printing material box that can be detachably mounted on the box mounting part of a liquid spraying device; wherein the printing material box includes a main body for containing printing material, an identification part for recording identification information, and an optical structure for guiding light, and the identification part can be optically read by a reading part on the box mounting part via the optical structure.
[0008] In the above technical solution, the reading unit completes the identification of the identification unit through the light guiding effect of the optical structure on the printed material box. This makes the identification unit not directly exposed to the outside, and it is not easily affected by external factors and damaged by dirt. At the same time, it also has the advantage of high identification success rate.
[0009] According to a specific embodiment of the present invention, the optical structure is a reflective optical component, and the light from the identification unit can be received by the reading unit after being reflected by the reflective optical component, so that the identification unit can be identified and read by the reading unit.
[0010] Furthermore, the identification part is located below the reflective optical component in the height direction of the printed material box.
[0011] Furthermore, the reflective optical component includes at least a reflector that is tilted relative to the mounting direction of the printed material box.
[0012] According to another specific embodiment of the present invention, the optical structure is a refractive optical component, and the light from the identification part can be received by the reading part after being refracted by the refractive optical component, so that the identification part can be identified and read by the reading part.
[0013] Furthermore, in the mounting direction of the printed material box, the refractive optical component is located in front of the identification section.
[0014] Furthermore, the refractive optical component includes a lens, which is preferably configured to magnify the image of the recognition unit.
[0015] Furthermore, the identification part is detachably mounted on the printed material box via a connecting part.
[0016] According to a specific embodiment of the present invention, the main body is a rigid shell structure, which includes a printing material receiving cavity for directly accommodating printing materials.
[0017] In the above technical solution, the printing material (e.g., ink) is directly contained in the printing material receiving cavity of the shell, which simplifies the production process compared to the technical solution of using a flexible bag to contain ink.
[0018] Furthermore, the main body includes an inflation chamber, which can replenish gas into the printing material receiving cavity to discharge the printing material inside the printing material receiving cavity.
[0019] To more clearly illustrate the purpose, technical solution, and advantages of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0031] Many specific details are set forth in the following description in conjunction with embodiments to provide a full understanding of the present invention. However, it should be understood that the following embodiments and detailed descriptions are for illustrative purposes only and do not limit the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0032] Example 1
[0033] like Figure 1 As shown, the printing material box 100 of this embodiment can be detachably mounted on the box mounting part 900 of the liquid jetting device. The printing material box 100 includes a main body 110 that is generally rectangular in shape, a printing material receiving part 110a formed inside the main body 110, and a printing material supply part. The printing material receiving part 110a is used to receive printing material. The printing material supply part is provided, for example, on the front side of the main body 110 (the side facing the reading part 93). When the printing material box 100 is mounted on the box mounting part 900, the printing material in the printing material receiving part 110a can be supplied to the material inlet part on the box mounting part 900 through the printing material supply part.
[0034] Specifically, the box mounting section 900 is equipped with a reading section 93, such as a camera, and the printing material box 100 is equipped with an identification section 120 for recording identification information. The identification section 120 can be read by the reading section 93, and the liquid spraying device can then acquire the identification information in the identification section 120. For example, the identification information on the identification section 120 may be QR code information, barcode information, or other pattern information, etc., and is not limited here. In this embodiment, the operation of the reading section 93 to read the identification information of the identification section 120 can be performed during the installation process of the printing material box 100, or when the printing material box 100 is installed in a predetermined position (including when it is in place).
[0035] The identification part 120 is hidden inside the printed material box 100, for example... Figure 1 The light is hidden in a recess on the upper part of the main body 110. The printing material box 100 is provided with an optical structure for guiding light. During the installation of the printing material box 100 / when it is installed in a predetermined position, the identification unit 120 is optically read by the reading unit 93 on the box mounting part 900 through the light guided by the optical structure. Further, the optical structure in Embodiment 1 is specifically a reflective optical component 102 mounted on the main body 110. The light from the identification unit 120 is reflected by this reflective optical component 102 and received by the reading unit 93, allowing the identification unit 120 to be identified and read by the reading unit 93.
[0036] In Example 1, in the mounting direction of the printing material box 100 ( Figure 1 The reflective optical component 102 is located behind the reading unit 93 in the direction from left to right. Figure 1 (Corresponding to the left of the reading unit 93), the identification unit 120 is located on the side of the reflective optical component 102 in the height direction, specifically below the reflective optical component 102. This allows the identification unit 120 to be hidden without being directly exposed.
[0037] Please continue reading. Figure 1 The reflective optical component 102 includes at least a reflector 103 that is inclined relative to the mounting direction of the printing material box 100. The reflective effect of the reflector 103 enables the reading unit 93 to read the identification unit 120. The reflector 103 can be a fixed reflector or a movable reflector. It is understood that when a movable reflector is used, the movable reflector can change position during the installation of the printing material box 100 / when it is installed in place, so that the reading unit 93 can read the position of the identification unit 120.
[0038] Example 2
[0039] like Figures 2-3As shown, the main difference between Embodiment 2 and Embodiment 1 is that the optical structure is specifically a refractive optical component 104 mounted on the main body 110. The light from the identification unit 120 is refracted by the refractive optical component 104 and received by the reading unit 93, so that the identification unit 120 can be identified and read by the reading unit 93. Specifically, in the mounting direction of the printing material box 100, the refractive optical component 104 is located between the reading unit 93 and the identification unit 120, that is, in the mounting direction of the printing material box 100, the refractive optical component 104 is located in front of the identification unit 120. Figure 2 and 3 (Corresponding to the right of the recognition unit 120). The refractive optical component 104 includes, for example, a lens 105, which can be selectively read and recognized by the reading unit 93 by magnifying or reducing the image of the recognition unit 120; Figure 2-3 The example shown only illustrates a single lens, but this embodiment is not limited to that.
[0040] In the embodiment, the reading unit 93 is, for example, a camera. Optical reading is preferably performed between the reading unit 93 and the recognition unit 120, and this distance is specifically the focal length of the camera. In the embodiment, the setting of the recognition unit 120 can be made more convenient by setting the refractive optical component 104. For example, the recognition unit 120 is set on the rear side wall 101 of the main body 110 away from the reading unit 93, and is preferably set in a detachable manner through the connecting part 130.
[0041] Among them, the joint 130 is, for example, Figure 2-3 The slot structure shown in the figure can also be connected by screws or magnetic means between the connecting part 130 and the identification part 120 in other embodiments, which will not be elaborated here.
[0042] Example 3
[0043] like Figures 4-6 As shown, the printing material box 100 in Embodiment 3 is designed for the reading conditions of the reading unit 93. Other structures can be referred to in Embodiments 1-2 or related structures in the prior art. Specifically, when the displacement of the printing material box 100 along its mounting direction exceeds a set reading threshold, the reading unit 93 is activated and begins to optically read the recognition unit 120.
[0044] Furthermore, at least one of the printing material box 100 and the box mounting part 900 is provided with a movable part 910. During at least a portion of the installation process of the printing material box 100, the movable part 910 moves. When the displacement of the movable part 910 exceeds a set reading threshold, the reading part 93 is activated and begins optical reading of the recognition part 120. An exemplary mounting position of the movable part 910 is on the end face 901 of the box mounting part 900 facing the printing material box 100. Correspondingly, an actuating part 140 is provided on the end face 901 of the printing material box 100 facing the box mounting part 900. During the installation process of the printing material box 100, the actuating part 140 contacts the movable part 910, causing the movable part 910 to move. As the installation continues, the actuating part 140 continuously acts on the movable part 910, causing the displacement of the movable part 910 to change and exceed the set reading threshold. The specific process is as follows: Figures 4-6 As shown.
[0045] It is understood that the movement of the movable part 910 can be sliding, rotating, or a change in position caused by deformation of the movable part 910 itself, etc. This embodiment does not limit these possibilities and will not elaborate on them further. In this embodiment, by setting the movable part 910, the reading timing of the reading part 93 can be controlled. In this way, the reading part 93 does not need to be kept in a normally open state but is only turned on when needed, which helps to extend the service life of the reading part 93.
[0046] Example 4
[0047] like Figures 7-9 As shown, the printing material box 100 in Embodiment 4 is designed for the main body 110 of the printing material box 100. Other structures can be referred to in Embodiments 1-3 or related structures in the prior art, which will not be elaborated here.
[0048] In embodiment 4, the main body 110 of the printing material box 100 is specifically a rigid shell structure, which includes a printing material receiving cavity 111 and an inflation cavity 112. The printing material receiving cavity 111 is provided by the printing material receiving part 110a (i.e., the printing material receiving cavity 111 is used to directly contain the printing material). The inflation cavity 112 can supplement the printing material receiving cavity 111 with gas to discharge the printing material in the printing material receiving cavity 111 to the box mounting part 900, specifically, the discharged material is supplied to the material inlet on the box mounting part 900.
[0049] The box mounting section 900 is equipped with an inflation structure 920 for inflating the inflation chamber 112. The main body 110 is equipped with an inflation port 114 that is adapted to the inflation structure 920, and the inflation port 114 is interconnected with the inflation chamber 112. When the printing material box 100 is installed in place, the inflation structure 920 and the inflation port 114 of the inflation chamber 112 combine to inflate the inflation chamber 112. The gas supplied to the inflation chamber 112 through the inflation structure 920 can be air or other gases such as inert gases.
[0050] Preferably, a sealing structure is provided at the junction of the air inlet 114 of the air chamber 112 and the air structure 920. The sealing structure is, for example, a sealing ring / gasket, to better maintain the connection effectiveness between the air chamber 112 and the air structure 920.
[0051] Furthermore, in this embodiment, a one-way valve assembly 113 is provided between the inflation chamber 112 and the printing material receiving chamber 111. When the pressure in the inflation chamber 112 increases, the one-way valve assembly 113 is opened to replenish gas into the printing material receiving chamber 111. Exemplarily, the one-way valve assembly 113 includes a valve body 1131, a valve plate 1132, and an elastic element 1133. The valve body 1131 is fixedly disposed relative to the wall of the main body 110 and has a channel 1134 thereon. The valve plate 1132 is movably disposed in the channel 1134 and can switch between different positions of keeping the channel 1134 open and closing the channel 1134. The elastic element 1133 is mounted on the valve body 1131 to keep the valve plate 1132 in the closed channel 1134 position under natural, unforced conditions. Figure 9 As shown.
[0052] When the printing material box 100 is installed in the predetermined position and inflated into the inflation chamber 112 by the inflation structure 920, the pressure inside the inflation chamber 112 gradually increases, causing the valve plate 1132 in the one-way valve assembly 113 to move and open the channel 1134. The printing material receiving chamber 111 can then be replenished with gas. Under the action of this air / gas entering the printing material receiving chamber 111, the printing material in the printing material receiving chamber 111 can be discharged into the material inlet on the box mounting part 900. When the inflation structure 920 stops inflating, the valve plate 1132 returns to the position of closing the channel 1134 under the action of the elastic element 1133. At this time, a certain negative pressure will be formed inside the printing material receiving chamber 111, and the printing material will no longer be discharged.
[0053] In Example 4, a rigid shell is used to provide the printing material receiving cavity 111 to directly contain the printing material (e.g., ink), which simplifies the production process compared to the prior art's use of a flexible bag to contain the ink.
[0054] Example 5
[0055] like Figures 10-11 As shown, the printing material box 100 of Embodiment 5 is designed for the main body 110 of the printing material box 100. Other structures can be referred to the aforementioned embodiments, and will not be elaborated here.
[0056] In Embodiment 5, the main body 110 includes two or more parts, at least a first part 112 for storing printing materials and a second part 113 having an identification portion 120. When the printing material box 100 is installed onto the box mounting portion 900, the first part 112 and the second part 113 can be assembled together and installed together, or they can be installed separately (in no particular order). The following description uses an example where the main body 110 includes only the first part 112 and the second part 113; extensions can be made based on this example when there are more parts.
[0057] The first part 112 and the second part 113 are installed separately; preferably, a joint 114 is provided between the first part 112 and the second part 113. The joint 114 is used to provide a limit when the first part 112 and the second part 113 are both installed in place, so as to keep the first part 112 and the second part 113 stably installed on the box mounting part 900 without automatically detaching.
[0058] For example, the connecting portion 114 is specifically a snap-fit connecting portion 114. In other embodiments, the connecting portion 114 may also adopt, for example, magnetic or other connecting forms, which will not be elaborated here.
[0059] Please continue reading. Figure 11 The connecting part 114 includes a first snap-fit member 1141 located on the first part 112 and a second snap-fit member 1142 located on the second part 113. In the embodiment, when the printing material box 100 is installed, the first part 112 located below can be installed first, and then the second part 113 located above can be installed. When the second part 113 cooperates with the limiting mechanism 912 of the box mounting part 900, the first snap-fit member 1141 and the second snap-fit member 1142 also form a limiting cooperation, that is, the first part 112 and the second part 113 are simultaneously fixed into the box mounting part 900.
[0060] In Example 5, the main body 110 of the printing material box 100 is divided into at least two parts to provide an identification part 120 and a space for storing printing materials, respectively. The identification part 120 is reusable, which facilitates recycling and reduces costs.
[0061] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
