[0057] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0058] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0059] The write-reading device provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0060] Reference Figures 1-17 The write-reading device provided by the embodiments of the present application can include a device body 100 and a write-reading assembly 200.

[0061] The device body 100 can be provided with a fixing groove 121, which can be used for inserting at least part of the printing consumable 300. The write-reading assembly 200 can be arranged on the device body 100. When at least part of the printing consumable 300 is inserted into the fixing groove 121, the groove wall of the fixing groove 121 is limited in cooperation with the printing consumable 300 in a first direction a, and the chip 302 of the printing consumable 300 is electrically connected with the write-reading assembly 200. Here, the first direction a can be perpendicular to the insertion direction of the printing consumable 300, and the first direction a can be perpendicular to the width direction of the printing consumable 300.

[0062] In the embodiments of the present application, at least part of the printing consumable 300 is inserted into the fixing groove 121 of the device body 100, and the fixing groove 121 is limited in cooperation with the printing consumable 300 in the first direction a, so that the code writing and reading device can be fixed on the printing consumable 300, so that the operator does not need to hold the code writing and reading device, and the code writing and reading assembly 200 can be in good contact with the chip 302 of the printing consumable 300 through the limiting cooperation of the groove wall of the fixing groove 121 and the printing consumable 300, so as to ensure the stability of data transmission, thereby realizing data upgrading of the chip 302. In this way, the hands of the operator can be freed, and the code writing and reading assembly 200 of the code writing and reading device is not easily disconnected from the chip 302 by external factors, thereby ensuring the stability and integrity of data transmission, thereby improving the success rate of data upgrading.

[0063] In the optional embodiments of the present application, the code writing and reading device can further include a positioning member 130, and the positioning member 130 can be arranged on the device body 100, and the positioning member 130 can be provided with a positioning space 134.

[0064] In the case that the printing consumable 300 is the first printing consumable 320, part of the first printing consumable 320 can extend into the positioning space 134, and in the second direction b, the positioning member 130 can be limited in cooperation with the first printing consumable 320. Here, the second direction b can be perpendicular to the insertion direction of the printing consumable 300, and the second direction b can be consistent with the width direction of the printing consumable 300. In this way, the first printing consumable 320 inserted into the fixing groove 121 can be limited in the second direction b by the positioning member 130, thereby preventing the first printing consumable 320 from being offset in the second direction b after being inserted into the fixing groove 121, thereby causing the chip 302 to be disconnected from the code writing and reading assembly 200.

[0065] In the case that the printing consumable 300 is the second printing consumable 310, the groove wall of the fixing groove 121 is limited in cooperation with the second printing consumable 310 in the second direction b, and in this way, the groove wall of the fixing groove 121 can limit the second printing consumable 310 in the second direction b to prevent the second printing consumable 310 from being offset in the second direction b after being inserted into the fixing groove 121, thereby causing the chip 302 to be disconnected from the code writing and reading assembly 200.

[0066] And the positioning member 130 can abut against the second print consumable 310 in the first direction a. In this way, the positioning member 130 can limit the second print consumable 310 in the first direction a, and assist in limiting the second print consumable 310 in the first direction a, thereby further preventing the second print consumable 310 from shaking in the first direction a, and thereby further improving the connection stability between the chip 302 of the second print consumable 310 and the code reading and writing assembly 200. Of course, the positioning member 130 can also not abut against the second print consumable 310 in the first direction a, that is, the positioning member 130 can also not limit the second print consumable 310 in the first direction a, for example, the slot wall of the fixing slot 121 can directly limit the second print consumable 310 in the first direction a.

[0067] In other embodiments, the code reading and writing device can also not include the positioning member 130. And the slot wall of the fixing slot 121 can also not limit the second print consumable 310 in the second direction b.

[0068] In optional embodiments, the positioning member 130 is movably arranged on the device body 100, and the positioning member 130 can move along the first direction between the first position and the second position.

[0069] Wherein, when the positioning member 130 is located at the first position, at least part of the positioning member 130 can be located in the fixing slot 121 and can limit the first print consumable 320 in the second direction b, that is, the positioning member 130 can only limit the first print consumable 320 in the second direction b when it is located at the first position.

[0070] When the positioning member 130 is located at the second position, the positioning member 130 can limit the second print consumable 310 in the first direction a, that is, when at least part of the second print consumable 310 is inserted into the fixing slot 121, the positioning member 130 is switched to the second position, and at this time the positioning member 130 can limit the second print consumable 310 in the first direction a. And when the positioning member 130 is located at the second position, the positioning member 130 can release the limitation of the first print consumable 320 in the second direction b.

[0071] It should be noted that when at least part of the second print consumable 310 extends into the fixing slot 121, the positioning member 130 moves to the second position. Specifically, the second print consumable 310 can push the positioning member 130 to move upward, so that the positioning member 130 avoids the second print consumable 310, thereby avoiding the positioning member 130 hindering the movement of the second print consumable 310, thereby making the code reading and writing device applicable to two different widths of print consumables 300, thereby improving the versatility of the code reading and writing device.

[0072] Here, the width of the second printing consumable 310 is greater than the width of the first printing consumable 320.

[0073] In an optional embodiment, the positioning member 130 can be connected with the device body 100 through the elastic member 140, and the elastic member 140 can be used to drive the positioning member 130 to return from the second position to the first position. In this way, the positioning member 130 can be facilitated to return from the second position to the first position, so that the positioning member 130 can position the first printing consumable 320 again. Here, the elastic member 140 can be a spring.

[0074] Of course, the positioning member 130 can also not be connected with the device body 100 through the elastic member 140, for example, the positioning member 130 is only in sliding connection with the device body 100, and the positioning member 130 can rely on its own gravity to return from the second position to the first position.

[0075] In an optional embodiment, as shown in Figure 2 and Figure 4 , the fixed slot 121 can be provided with a positioning slot 122 on the slot wall away from the slot opening of the fixed slot 121, the positioning slot 122 can be used for the part of the first printing consumable 320 to be embedded, and in the first direction, the slot wall of the positioning slot 122 is in limiting cooperation with the first printing consumable 320. In this way, the first printing consumable 320 can be further limited in the second direction b, so that the first printing consumable 320 can be prevented from tilting in the second direction b after being inserted into the fixed slot 121, and the connection stability of the first printing consumable 320 with the code reading and writing device can be improved.

[0076] In other embodiments, the fixed slot 121 can also not be provided with the positioning slot 122 on the slot wall away from the slot opening of the fixed slot 121.

[0077] Optionally, the code reading and writing device comprises at least two positioning members 130, the width of the positioning space 134 of each positioning member 130 in the second direction b is different, so that each positioning member 130 can limit the printing consumable 300 with different widths respectively. Here, each positioning member 130 can be connected with the device body 100 through the elastic member 140, and can move relative to the device body 100 along the first direction a.

[0078] In an optional embodiment, as shown in Figures 15-17 , the positioning member 130 can comprise a first positioning part 131, a second positioning part 132 and a connecting part 133, the first positioning part 131 and the second positioning part 132 can be connected through the connecting part 133, the first positioning part 131, the connecting part 133 and the second positioning part 132 form the positioning space 134, and the second direction b, the first positioning part 131 and the second positioning part 132 can be in limiting cooperation with the first printing consumable 320.

[0079] Optionally, in the first direction a, the connecting portion 133 can be in position-limiting cooperation with the first printing consumable 320. In this way, the positioning member 130 can limit the first printing consumable 320 in the first direction a, thereby assisting in limiting the first printing consumable 320 in the first direction a, and further preventing the first printing consumable 320 from shaking in the first direction a, thereby further improving the connection stability of the chip 302 of the first printing consumable 320 and the code reading and writing assembly 200.

[0080] Further optionally, as shown in Figure 15 the first direction of insertion of the printing consumable 300, the vertical distance between the first guide surface 1304 and the connecting portion 133 gradually increases. In this way, when the second printing consumable 310 is inserted into the fixing groove 121, the first guide surface 1304 can make the positioning member 130 be pushed away more smoothly, so as to reduce the mutual resistance between the positioning member 130 and the second printing consumable 310, thereby avoiding the problem of jamming.

[0081] Of course, the side of the first positioning portion 131 and the second positioning portion 132 away from the connecting portion 133 can also not be provided with the first guide surface 1304.

[0082] Further optionally, as shown in Figure 17 the first positioning portion 131 and the second positioning portion 132 can each include a first part 1301 and a second part 1302 connected to the first part 1301, the second part 1302 is located on the side of the first part 1301 away from the slot opening of the fixing groove 121, and the first guide surface 1304 can be provided on the first part 1301.

[0083] In the direction from the second part 1302 to the first part 1301, the spacing between the first part 1301 of the first positioning portion 131 and the first part 1301 of the second positioning portion 132 in the second direction b can gradually increase. In this way, part of the first printing consumable 320 can extend into the positioning space 134. Of course, the spacing between the first part 1301 of the first positioning portion 131 and the first part 1301 of the second positioning portion 132 in the direction from the second part 1302 to the first part 1301 can be constant or gradually decrease.

[0084] In the direction from the first portion 1301 to the second portion 1302, i.e. in the insertion direction of the print consumable 300, the distance between the second portion 1302 of the first positioning part 131 and the second portion 1302 of the second positioning part 132 in the second direction b gradually increases. In this embodiment, in the insertion direction of the print consumable 300, a horn-like guiding structure can be formed between the second portion 1302 of the first positioning part 131 and the second portion 1302 of the second positioning part 132, which can automatically correct the initial insertion angle deviation of the first print consumable 320, ensure the accurate alignment of the first print consumable 320 along the axis of the fixed slot 121, and avoid jamming or poor contact caused by skewing. Moreover, since the distance between the first portion 1301 of the first positioning part 131 and the first portion 1301 of the second positioning part 132 is relatively small, the position of the first print consumable 320 can be stabilized. As the insertion depth of the first print consumable 320 increases, the distance between the second portion 1302 of the first positioning part 131 and the second portion 1302 of the second positioning part 132 expands, which can reduce the contact area and friction between the positioning part 130 and the first print consumable 320, thereby facilitating smoother insertion and removal operations. Meanwhile, when the first print consumable 320 is removed, the second portion 1302 of the first positioning part 131 and the second portion 1302 of the second positioning part 132 are less likely to hinder the first print consumable 320.

[0085] Of course, the distance between the second portion 1302 of the first positioning part 131 and the second portion 1302 of the second positioning part 132 in the second direction b can also be equal to the distance between the first portion 1301 of the first positioning part 131 and the first portion 1301 of the second positioning part 132 in the second direction b.

[0086] In some embodiments, the device body 100 can include a first fixed shell 110 and a second fixed shell 120 connected to the first fixed shell 110, wherein the first fixed shell 110 and the second fixed shell 120 can be clamped or connected by a fixing part. In this embodiment, a plurality of first buckles 111 can be provided on the first fixed shell 110, and a plurality of second buckles 124 can be provided on the second fixed shell 120. Each first buckle 111 is clamped with each second buckle 124 one by one to achieve the clamping of the first fixed shell 110 and the second fixed shell 120.

[0087] The second fixed shell 120 is provided with a fixed slot 121, and a sliding hole 12112 can be provided on the slot wall of the first fixed shell 110 close to the second fixed shell 120. The positioning part 130 is slidingly arranged in the sliding hole 12112, and one end of the elastic part 140 can be connected to the part of the first fixed shell 110 away from the second fixed shell 120, and the other end of the elastic part 140 is connected to the connecting part 133 of the positioning part 130.

[0088] Optionally, asFigure 7 As shown, the second fixed shell 120 can be provided with a first limiting baffle 126, the first limiting baffle 126 can be arranged around the sliding hole 12112, and the positioning member 130 can be in sliding connection with the first limiting baffle 126. In this embodiment, the first limiting baffle 126 can play a guiding role and a limiting role on the positioning member 130, preventing the positioning member 130 from deviating in other directions. Further, the first fixed shell 110 can also be provided with a second limiting baffle 112, the second limiting baffle 112 can be opposite to the first limiting baffle 126, and the structure of the second limiting baffle 112 is matched with that of the first limiting baffle 126, part of the positioning member 130 can extend into the space surrounded by the second limiting baffle 112, and the second limiting baffle 112 can play a guiding and limiting role on the positioning member 130, to further prevent the positioning member 130 from deviating.

[0089] Here, one of the first limiting baffle 126 and the positioning member 130 can be provided with a sliding groove 1261, and the other can be provided with a sliding part 1303, the extension direction of the sliding groove 1261 is parallel to the first direction a, and the sliding part 1303 is located in the sliding groove 1261 and can slide relative to the sliding groove 1261. Optionally, the first limiting baffle 126 is provided with two sliding grooves 1261, and the first positioning part 131 and the second positioning part 132 of the positioning member 130 can be provided with sliding parts 1303, respectively, and each sliding part 1303 is located in the corresponding sliding groove 1261.

[0090] Optionally, the positioning member 130 further comprises a limiting part 136, the limiting part 136 is connected with the connecting part 133, the limiting part 136 can be located on the side of the first limiting baffle 126 away from the fixed groove 121, and in the first direction a, the first limiting baffle 126 and the limiting part 136 can be in limiting cooperation. In this way, through the limiting cooperation of the first limiting baffle 126 and the limiting part 136, the positioning member 130 can be limited and supported, to prevent the positioning member 130 from separating from the elastic member 140. In this embodiment, the positioning member 130 can be provided with a mounting groove 135, part of the elastic member 140 can be located in the mounting groove 135 and abut against the groove bottom of the mounting groove 135.

[0091] In an optional embodiment, as shown in Figure 9 and Figure 11 As shown, the write-read code assembly 200 can include an electrically connected plate 220 and an elastic connecting member 230 electrically connected with the electrically connected plate 220, the elastic connecting member 230 can be used for electrically connecting with the chip 302, the electrically connected plate 220 can be arranged on the first groove wall 1211 of the fixed groove 121, and the elastic connecting member 230 is located in the fixed groove 121, so as to facilitate the contact between the elastic connecting member 230 and the chip 302. Here, the elastic connecting member 230 can be a spring sheet.

[0092] In addition, the second groove wall 1212 of the fixing groove 121 can be provided with a protrusion 12121, and the protrusion 12121 can be limited in cooperation with the printing consumable 300 in the first direction a, so as to make the elastic connecting piece 230 electrically connected with the chip 302. Here, in the case that the protrusion 12121 is limited in cooperation with the printing consumable 300 in the first direction a, the distance between the printing consumable 300 and the electric connecting plate 220 is less than the length of the elastic connecting piece 230 when the elastic connecting piece 230 is not deformed, that is, when the printing consumable 300 is located on the protrusion 12121, the printing consumable 300 can extrude the elastic connecting piece 230, so that the elastic connecting piece 230 is deformed to keep good contact with the chip 302.

[0093] The protrusion 12121 is formed between the side close to the slot of the fixing groove 121 and the second groove wall 1212, and the projection of the avoiding part 12122 in the first direction a can cover the area where the elastic connecting piece 230 is located in the first direction a, and in the case that the printing consumable 300 is located in the avoiding part 12122, the distance between the printing consumable 300 and the electric connecting plate 220 is greater than or equal to the length of the elastic connecting piece 230 when the elastic connecting piece 230 is not deformed. In this way, when the chip 302 completes data upgrading, the printing consumable 300 is pulled out outward, and the printing consumable 300 and the elastic connecting piece 230 are not easy to interfere with each other to cause damage to the elastic connecting piece 230 or the printing consumable 300.

[0094] It should be noted that the printing consumable 300 is provided with a groove 304, specifically, the printing consumable 300 includes a consumable body 301 and a chip 302, and the chip 302 is arranged at the top end of the consumable body 301, and the groove 304 is arranged on the consumable body 301. The groove 304 is used to avoid the components on the printer, and the groove 304 can be arranged close to the first end of the printing consumable 300, here, the first end of the printing consumable 300 can be the end far away from the ink inlet of the printing consumable 300, and the chip 302 can be located on the side close to the ink inlet of the groove 304.

[0095] In this embodiment, during the process of the printing consumable 300 being pulled out of the fixing slot 121, when the elastic connector 230 is opposite to the groove 304, the elastic connector 230 restores its deformation and partially extends into the groove 304. As the printing consumable 300 moves outward, the groove wall of the groove 304 away from the chip 302 may interfere with the elastic connector 230. However, when the printing consumable 300 moves to the avoidance part 12122, the printing consumable 300 moves a certain distance away from the elastic connector 230 (i.e., the printing consumable 300 decreases due to its own weight), so that the distance between the printing consumable 300 and the electrical connection plate 220 is greater than or equal to the length of the elastic connector 230 when it is not deformed. Therefore, during the outward movement of the printing consumable 300, the groove wall of the groove 304 away from the chip 302 can avoid the elastic connector 230, thus making it less likely to interfere with the elastic connector 230.

[0096] Optionally, the distance between the end of the protrusion 12121 near the opening of the fixed groove 121 and the elastic connector 230 in the moving direction of the printing consumable 300 can be greater than or equal to the thickness of the groove wall of the groove 304 away from the chip 302.

[0097] In other embodiments, in the insertion direction of the printing consumable 300, that is, in the orientation of the opening of the fixing groove 121, the length of the protrusion 12121 can be equal to the length of the second groove wall 1212, that is, no clearance portion 12122 is formed between the side of the protrusion 12121 near the opening of the fixing groove 121 and the second groove wall 1212.

[0098] Optionally, such as Figure 7 As shown, an elastic limiting plate 12111 is provided on the first groove wall 1211. When the protrusion 12121 and the printing consumable 300 are in upper limit engagement in the first direction a, the elastic limiting plate 12111 and the printing consumable 300 are in upper limit engagement in the first direction a. The elastic limiting plate 12111 can restrict the printing consumable 300 from moving away from the protrusion 12121, thereby improving the stability of the printing consumable 300. In this embodiment, the elastic limiting plate 12111 can be located on the side of the electrical connection plate 220 away from the groove opening of the fixing groove 121. This arrangement facilitates the elastic limiting plate 12111 in limiting the front end position of the printing consumable 300, that is, limiting the position of the printing consumable 300 near the bottom of the fixing groove 121.

[0099] Of course, the elastic limiting plate 12111 may not be provided on the first groove wall 1211.

[0100] Optionally, such as Figure 4As shown, the convex portion 12121 is provided with a second guide surface 12123 on the side close to the slot opening of the fixing groove 121. In the insertion direction of the print consumable 300, the vertical distance between the second guide surface 12123 and the second groove wall 1212 gradually increases. The second guide surface 12123 in this embodiment can guide the print consumable 300, so as to facilitate the movement of the print consumable 300 above the convex portion 12121 when the print consumable 300 is inserted into the fixing groove 121.

[0101] Of course, the convex portion 12121 can also not be provided with the second guide surface 12123 on the side close to the slot opening of the fixing groove 121.

[0102] Further optionally, the second groove wall 1212 can be provided with a plurality of convex portions 12121, the plurality of convex portions 12121 can be arranged in parallel, and each convex portion 12121 is limited and matched with the print consumable 300 in the first direction a. In this way, the stability of the print consumable 300 in the fixing groove 121 can be improved.

[0103] In some embodiments, the print consumable 300 is provided with a handle 303, which is used to connect with the printer.

[0104] In optional embodiments, as shown, Figure 4 The device body 100 can also be provided with a avoiding space 123, which can be located on the side of the fixing groove 121 away from the slot opening of the fixing groove 121, and the avoiding space 123 can be used for the handle 303 to extend into. In this way, the handle 303 can be prevented from being squeezed and damaged.

[0105] Of course, the device body 100 can also not be provided with the avoiding space 123.

[0106] In optional embodiments, the write-read code assembly 200 can further include a write-read code element 210, and the electrically connected board 220 described above can be electrically connected with the write-read code element 210. The write-read code element 210 can be used for writing and reading the chip 302, so as to upgrade the data of the chip 302. Here, the write-read code element 210 can be a circuit board.

[0107] The first fixing shell 110 and the second fixing shell 120 described above form a mounting space therebetween, and the write-read code element 210 can be arranged in the mounting space.

[0108] Optionally, the write-read code assembly 200 can further comprise a power interface 240 and an indicator light 250, both of which can be electrically connected with the write-read code element 210. The power interface 240 can be used to be electrically connected with a power line for charging the write-read code element 210. The indicator light 250 can be used to display the power-on state of the write-read code element 210, such as when the power interface 240 is electrically connected with the power line, the indicator light 250 emits light. Of course, the indicator light 250 can be used to display the connection state of the write-read code element 210 with the chip 302 and / or whether the data processing of the chip 302 is completed, such as when the indicator light 250 emits red light, it indicates that the write-read code element 210 maintains the state of electrical connection with the chip 302, and when the indicator light 250 emits green light, it indicates that the write-read code element 210 completes the data processing of the chip 302, such as the completion of the data upgrade of the chip 302.

[0109] Here, the first fixed shell 110 can be provided with a through hole for the indicator light 250 to extend out.
