Description

TECHNICAL FIELD

[0001] The present application relates to the field of copying equipment accessories, in particular to a recognition device suitable for a Canon copier toner cartridge. BACKGROUND

[0002] The Canon copier is a commonly used copying equipment in the market, and its toner cartridge is one of the main consumables. At present, the toner cartridges used on Canon copiers in different countries and regions are all special, such as TK8348 and 2552, 3252, 4052, 5052, 6052 and other types of copies. The identification device for identifying the toner cartridge is basically the same. The copier powder holder on this type of copier can install multiple toner cartridges, and the toner cartridge head insertion part on the copier powder holder is installed with a large and a small conductive ring. The large conductive ring is sleeved with the small conductive ring. When there is no toner cartridge installed in the toner cartridge head insertion part of the copier powder holder, the large conductive ring and the small conductive ring are in contact with each other through the inductive spring, and the copier can judge that there is no toner cartridge installed. When the toner cartridge is inserted into the toner cartridge head insertion part, the spacer on the special toner cartridge will push the inductive spring away from each other. Thus, the large conductive ring and the small conductive ring cannot be in contact with each other, and the copier can judge that the toner cartridge has been installed in place and can work normally. However, since the Canon copier uses toner cartridges in different countries and regions, even if they are of the same type, the spacers of the toner cartridges are different. Specifically, the position of the spacer is slightly different, because the copier powder holder used in different countries and regions of the Canon copier is installed with some protrusions between the inductive springs, which separate some inductive springs. At this time, only the carbon powder cartridge with the arrangement position of the spacer staggered with the pre-fixed position of the protrusion can be inserted into the toner cartridge head insertion part, and then separate the remaining inductive springs. Therefore, other substitute toner cartridges can only be used for one type of copier, and one type of toner cartridge is produced. However, in fact, except for the different positions of the spacer, more than 90% of the other glue structures of this type of toner cartridge are completely the same, which leads to poor universality, and different toner cartridges are needed for machines in each country and region, and manufacturers need to produce many different molds, increasing production costs.

[0003] And due to the changing market demand and the difficulty of toner cartridge production, some enterprises began to produce general toner cartridges to match the above-mentioned Kyocera copier. By making the partition piece separately detachable, different partition pieces are installed in different arrangements to match the copier in different regions. For example, Chinese Patent No. CN 215769363 U discloses a toner cartridge head cover with a screw-in area identification column, which includes a "head cover body and an area identification column, the head cover body is provided with a plurality of area identification column mounting holes, the inner wall of each area identification column mounting hole is provided with a plurality of guide grooves, the bottom end of each guide groove is provided with a guide slope and a positioning concave point, the guide groove and the positioning concave point are connected through the guide slope, the area identification column includes an area identification feature block and a cylinder located at the lower end of the area identification feature block, the cylinder is matched with the area identification column mounting hole, and the outer wall of the cylinder is provided with a plurality of positioning convex points matched with the positioning concave points". The invention patent realizes the position adjustment of the partition piece by inserting the identification column into different area identification column mounting holes, thereby solving the problem that a specific copier can only use a specific toner cartridge. However, the technical solution of the invention still has the following problems in actual production and transportation. The quality and stability of such a way cannot be guaranteed, and the identification column may be incorrectly installed in the incorrect area identification column mounting hole during the assembly process. Since the user is not aware of the pre-existing convex column position between the sensing tabs installed on the copier powder holder, once the installation is incorrect, the user cannot successfully solve the problem of the toner cartridge not being installed into the powder cartridge head insertion part. Secondly, the identification column may fall off during transportation, so it needs to be glued into the area identification column mounting hole, which will increase the process and cost.

[0004] Therefore, the identification device in the existing general Kyocera copier toner cartridge needs to be further improved. SUMMARY

[0005] The purpose of the present application is to provide an identification device suitable for a Kyocera copier toner cartridge.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following scheme: an identification device suitable for a Kyocera copier toner cartridge, which includes a toner cartridge cover, a positioning column protruding in the center of the toner cartridge cover, which can be inserted into the corresponding insertion hole on the copier powder holder, a plurality of identification parts are arranged in sequence and spaced apart on the toner cartridge cover along the circumference of the positioning column, which can be inserted into the ring groove located on the outer periphery of the insertion hole, and can separate the symmetrically installed sensing tabs in the ring groove from each other, and a positioning part is arranged on the toner cartridge cover, which can cooperate with the original buckle on the copier powder holder to lock the toner cartridge cover.

[0007] As a further aspect of the present application, the identification part comprises sleeves integrally formed with the outer wall of the toner cartridge cover end, the sleeves having cavities inside and openings at the end of the sleeves communicating with the cavities, and the sleeves being arranged in sequence and spaced apart along the circumferential periphery of the positioning column.

[0008] As a preferred aspect of the present application, the sleeves are circular tubes, and the outer periphery of the head end of the sleeves is provided with a chamfer.

[0009] As a further aspect of the present application, the identification part comprises sheet-shaped inserts integrally formed with the outer wall of the toner cartridge cover end, and the inserts being arranged in sequence and spaced apart along the circumferential periphery of the positioning column.

[0011] As a preferred aspect of the present application, the elastic members are springs.

[0012] As a preferred aspect of the present application, the edge of the inner wall of the expansion groove near the opening is provided with a anti-falling ring, and the tail end of the insert arranged in the expansion groove is provided with a blocking ring, and one side of the blocking ring and one side of the anti-falling ring abut together.

[0013] As a further aspect of the present application, the positioning part comprises clamping grooves respectively provided on the left and right sides of the toner cartridge cover corresponding to the original buckles on the powder holder of the copier, the clamping grooves having convex points in the center capable of being clamped together with the buckles, and the inner walls of the two sides of the clamping grooves being capable of being clamped on the upper and lower end edges of the corresponding buckles.

[0014] In summary, the present application has the following advantages over the prior art: the identification part formed by the tubular sleeves or sheet-shaped inserts or telescopically arranged inserts arranged on the outer wall of the toner cartridge cover end can easily cooperate with the Kyocera copier used in different countries and regions without any adjustment of the position of the identification part, thereby achieving more effective versatility, and there is no risk of the identification part falling off, and no additional process is required for assembly, thereby eliminating the problem of incorrect assembly in the traditional assembly process, reducing costs, increasing production efficiency, and ensuring the firmness in the transportation and use environment.

[0025] The following detailed description provides for various different embodiments or examples of the application. Of course, these are merely examples and are not intended to be limiting. Also, like reference numerals are used to designate corresponding parts throughout the several views, as can be used in different embodiments. These are used for a simple and clear description of the application, and do not represent a specific relationship between the different embodiments and / or structures being discussed.

The device can be rotated 90 degrees or other orientations in different positions, and the spatially relative terms used herein are intended to encompass such changes in position and orientation. Thus, a device that is described as being "above" or "below" another device can be oriented in any way in the drawings, and the spatially relative terms are used only to illustrate the device as shown in the drawings. The terms "first", "second", and the like, do not denote any absolute significance, but are used only to describe different elements or structures. Thus, a "first" and "second" feature can include one or more such features.

[0027] The application will be further described with reference to the drawings and the following detailed description: Figure 1 As shown in the structure diagram of the existing toner cartridge cover 1 and the removable partition 8, the toner cartridge cover 1 is provided with a plurality of mounting holes 81 around the center, and the tail end of the partition 8 is inserted into the mounting hole 81 for fixation. When the toner cartridge cover 1 needs to be installed in a specific area of the Kyocera copier, the partition 8 needs to be inserted into the mounting hole 81 to achieve the installation. However, this method has the risk of loosening and falling off, and needs to set up an additional process for assembly, which is time-consuming and laborious. Secondly, it should be noted that, as shown in the structure diagram of the existing toner cartridge cover 1 and the removable partition 8, Figure 2 Figure 3The position of installing the toner cartridge inside the existing copying machine such as TK8348 and various models of 2552, 2553, 2554, 3252, 3253, 3254, 3552, 3553, 3554, 4052, 4053, 4054, 5052, 5053, 5054, 6052, 6053, 6054, etc. shown in the figure has a long strip-shaped toner cartridge holder 4, and the toner cartridge holder 4 can install multiple toner cartridges 100, so multiple cartridge head insertion parts 9 are arranged in sequence and at intervals on the toner cartridge holder 4, the cartridge head insertion part 9 is a polygon, and has a insertion hole 91 in the center, the periphery of the insertion hole 91 is a concave annular groove 41, the annular groove 41 is a polygon, and a large and small two conductive rings are installed in the annular groove 41, the large conductive ring 93 is embedded on the circumferential inner wall of the annular groove 41, and the small conductive ring 94 is embedded on the circumferential periphery of the insertion hole 91, that is, the large conductive ring 93 is sleeved on the small conductive ring 94. The large conductive ring 93 and the small conductive ring 94 are respectively provided with multiple bent sensing springs 3 at intervals, and the sensing springs 3 on the large conductive ring 93 and the sensing springs 3 on the small conductive ring 94 are arranged in pairs and symmetrically. When the cartridge head insertion part 9 of the toner cartridge holder 4 is not installed with the toner cartridge 100, two adjacent sensing springs 3 can be in contact with each other. At this time, since the large conductive ring 93 and the small conductive ring 94 are in current conduction with each other through the mutually contacted sensing springs 3, the copying machine can judge that the toner cartridge 100 is not installed. When the toner cartridge 100 is inserted into the cartridge head insertion part 9, the separating piece 8 existing on the special toner cartridge will push the mutually contacted sensing springs 3 away from each other. Thus, the large conductive ring 93 and the small conductive ring 94 cannot conduct to each other, and the copying machine can judge that the toner cartridge 100 has been installed in place and can work normally. However, since the separating pieces 8 of the toner cartridges used in different countries and regions of the Kyocera copying machine are different, there are slight differences in the positions of the separating pieces 8. This is because the Kyocera copying machine has some protrusions 90 between the sensing springs 3 installed on the toner cartridge holder 4 in different countries and regions, which separate part of the sensing springs 3. At this time, only the toner cartridge with the arrangement position of the separating piece 8 staggered with the pre-fixed position of the protrusions 90 can be inserted into the cartridge head insertion part 9, and then separate the remaining sensing springs 3 from each other.

[0028] Therefore, as Figures 2 to 9As shown is a recognition device for a Canon copier toner cartridge provided by the present application, comprising a toner cartridge cover 1, the central protruding of the toner cartridge cover 1 is provided with a positioning column 11 which can be inserted into the corresponding insertion hole 91 on the copier powder holder 4, along the circumference of the positioning column 11, a plurality of recognition parts 2 which can be inserted into the annular groove 41 located on the circumference of the insertion hole 91 and can separate the symmetrically installed sensing spring 3 in the annular groove 41 are sequentially and spaced apart on the toner cartridge cover 1, and the positioning part 6 of the toner cartridge cover 1 is provided with a buckle 12 which can cooperate with the original buckle 12 on the copier powder holder 4 to lock the toner cartridge cover 1.

[0029] Among them, as Figures 2 to 5 As shown is the first embodiment of the present application, the recognition part 2 on the toner cartridge cover 1 comprises a sleeve 21 which is integrally formed with the outer wall of the end of the toner cartridge cover 1, the sleeve 21 is circular and tubular, has a cavity 22 inside, and has an opening at the end which communicates with the cavity 22, and each sleeve 21 is arranged along the circumferential periphery of the positioning column 11. The sleeve 21 is circular and tubular, and the outer periphery of the head end of the sleeve 21 is chamfered. When the toner cartridge 100 is inserted into the powder cartridge head insertion part 9, the sleeve 21 of the toner cartridge cover 1 will be inserted between the sensing springs 3, and when the protruding column 90 which is fixed in advance between the sensing springs 3 is encountered, the sleeve 21 can also sleeve the protruding column 90 in the cavity 22. In this way, no matter where the protruding column 90 is fixed between any two adjacent sensing springs 3, no adjustment of the position of the sleeve 21 is needed, that is, the recognition part 2 in this embodiment can easily cooperate with similar Canon copiers used in different countries and regions as exemplified above. In order to be more easily inserted between two adjacent sensing springs 3, the outer periphery of the head end of the sleeve 21 is chamfered. The integrally formed sleeve 21 can also reduce the number of molds, and only one mold is needed.

[0030] In addition, as Figure 6 and Figure 7 As shown is the second embodiment of the present application, it can be clearly seen from the figure that the second embodiment is basically the same as the first embodiment, only the shape of the recognition part 2 is different, the recognition part 2 comprises an arc-shaped sheet which is integrally formed with the outer wall of the end of the toner cartridge cover 1, each of the insertion pieces 23 is arranged along the circumferential periphery of the positioning column 11, and the head end of the insertion piece 23 has a chamfered outer edge. The insertion piece 23 in this embodiment can also be inserted between two adjacent sensing springs 3 as the sleeve 21 in the first embodiment, and when the protruding column 90 is encountered, the insertion piece 23 can be between the sensing spring 3 and the circumferential outer wall of the protruding column 90. Without special adjustment of the position of the insertion piece 23, it can also cooperate with similar Canon copiers used in different countries and regions as exemplified above.

[0031] In addition, as Figure 8 and Figure 9The third embodiment of the present application is shown, the identification part 2 includes the concave setting on the outer wall of the toner cartridge cover 1 end telescopic slot 24, each telescopic slot 24 along the circumferential outer periphery of the positioning column 11 sequentially spaced, respectively in the telescopic slot 24 can be telescopic setting plug 25, the tail end of the plug 25 and the bottom wall of the telescopic slot 24 between the elastic element 7 can keep the plug 25 head out of the telescopic slot 24, the elastic element 7 is a spring, the outer periphery of the plug 25 head is provided with a chamfer, when inserted into the ring groove 41, it is easier to push two adjacent sensing spring 3 apart. When the toner cartridge 100 is inserted into the powder cartridge head insertion part 9, the plug 25 on the toner cartridge cover 1 will be inserted between two adjacent sensing spring 3, and the two are separated; when encountering the protruding column 90 fixed in advance between the sensing spring 3, the plug 25 will be pressed back to the telescopic slot 24, in this way, without special adjustment of the position of the plug 25, it can be used on the above-mentioned similar Kyocera copier in different countries and regions. When the toner cartridge 100 is not installed on the copier powder holder 4 or transported, in order to prevent the plug 25 from being pushed out of the telescopic slot 24 by the elastic element 7, falling off. The edge of the inner wall of the telescopic slot 24 near the opening position is provided with a anti-off ring 241, the tail end of the plug 25 is provided with a stop ring 251 along the circumferential outer wall of the telescopic slot 24, one side of the stop ring 251 and one side of the anti-off ring 241 abut together.

[0032] When the toner cartridge 100 is inserted into the powder cartridge head insertion part 9, in order to fix the toner cartridge cover 1, the toner cartridge 100 is locked on the copier powder holder 4 by the positioning part 6. Specifically, the positioning part 6 includes a clamping groove 61 provided on the left and right sides of the toner cartridge cover 1 respectively corresponding to the original buckle 12 on the copier powder holder 4, the two clamping grooves 61 are mutually opposite and outwardly open "C" shape, the clamping groove 61 has a convex point 62 in the center which can be clamped together with the buckle 12; in order to prevent the toner cartridge cover 1 from shaking left and right after being fixed on the copier powder holder 4, the inner walls of the two sides of the clamping groove 61 can be clamped on the upper and lower end edges of the corresponding buckle 12 respectively.
