Technical Field

[0001] This utility model relates to the field of imaging equipment consumables technology, and in particular to a powder discharge component for a toner container. Background Technology

[0002] In existing electrophotographic image forming apparatuses (such as printers), the developing process is accomplished by the developer supplying toner to the electrostatic latent image on the surface of the photosensitive drum. This toner is supplied to the developer from a toner container.

[0003] However, when the toner container is connected to the printing equipment, the lack of an effective guiding structure may result in an unsmooth connection between the toner ejector and the printing equipment. Secondly, when the toner ejector is installed on the toner cartridge, the lack of a proper securing mechanism may lead to insufficient stability of the ejector on the cartridge. This lack of stability may affect the toner's performance and further impact print quality.

[0004] Based on this, in order to further improve the installation reliability of existing powder discharge components, we propose a powder discharge component for a toner container. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of an effective guiding structure and the potential for poor connection between the powder discharge component and the printing equipment, by proposing a powder discharge component for a toner container.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A clamping structure for clamping the powder cylinder is provided on the outside of the annular body. A base is formed at the bottom of the annular body, and a powder discharge port is formed in the middle of the base, which extends into the inner hole of the annular body. The powder cylinder forms a powder discharge channel through the annular body and the powder discharge port.

[0010] The front end of the annular body also has several positioning parts, and multiple guide parts are irregularly arranged on the free ends of the positioning parts.

[0011] Furthermore, several of the positioning portions are distributed circumferentially along the end face of the annular body;

[0012] The positioning part includes a columnar part, and an arc-shaped piece and a plug-in piece are formed on the end of the columnar part. The guide part is formed on the end of the arc-shaped piece.

[0013] Furthermore, the guide portion is formed on the upper side or lower side of the end of the positioning portion, and at least one guide slope is also formed on the end face of the guide portion.

[0014] Furthermore, it also includes a plug and a positioning groove formed on the end face of the annular body, the plug and the positioning groove being used for plugging and positioning with the positioning structure of the printing device.

[0015] Furthermore, the clamping structure includes a plurality of U-shaped grooves spaced apart on the outer periphery of the annular body, each U-shaped groove forming a spring piece on the annular body, wherein the thickness of the spring piece gradually increases along the insertion direction of the powder cylinder.

[0016] Furthermore, a side positioning plate is formed on the side of the annular body, and an upper connecting bracket is formed on the top of the annular body.

[0017] The present invention provides a powder discharge component for a toner container, which has the following advantages: The present invention features a guide portion formed at the end of an arc-shaped piece, the purpose of which is to allow the guide portion to be inserted into the connection slot of the printing device. A guide slope is formed on the free end of the guide portion. The guide slope design improves the smoothness of the guide portion's insertion into the two conductive contacts. Simultaneously, the design of multiple arc-shaped pieces ensures the stability of the connection positioning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 As an embodiment of this utility model, a powder discharge component for a toner container is disclosed. Specifically, the powder discharge component includes an annular body 1 for inserting a powder cartridge. In specific installation, the open end of the powder cartridge is first inserted into the annular body 1, and then the entire powder discharge component is inserted into the connector of the printer to complete the installation of the powder cartridge.

[0025] A clamping structure 2 for clamping the toner cartridge is provided on the outer side of the annular body 1. A base 3 is formed at the bottom of the annular body 1, and a toner discharge port 4 is formed in the middle of the base 3, which extends into the inner hole of the annular body 1. The toner cartridge forms a toner outlet channel through the annular body 1 and the toner discharge port 4. That is, in this embodiment, the toner discharge port 4 is used to adapt to the toner inlet of the printer. When the toner cartridge is installed, its open end is connected to the toner inlet of the printer through the air outlet channel mentioned above, so as to achieve toner supply to the printer.

[0026] The front end of the annular body 1 also has several positioning parts 5, and multiple guide parts 51 are irregularly arranged on the free ends of the positioning parts 5.

[0027] In some embodiments, a plurality of the positioning portions 5 are distributed circumferentially along the end face of the annular body 1 in this invention;

[0028] The positioning part 5 includes a columnar part 52, and an arc-shaped piece 53 and a plug-in piece 54 are formed on the end of the columnar part 52. The guide part 51 is formed on the end of the arc-shaped piece 53.

[0029] The guide portion 51 is formed on the upper side or lower side of the end of the positioning portion 5, and at least one guide slope 511 is also formed on the end face of the guide portion 51.

[0030] Specifically, in this embodiment, a guide portion 51 is formed at the end of the arc-shaped piece 53. The purpose of the guide portion 51 is to be inserted into the connection slot of the printing device. Of course, there are two conductive contacts in the connection slot of the printing device. When the arc-shaped piece 53 is not inserted, the two conductive contacts are in contact, and the printing device indicates that there is no toner cartridge.

[0031] When this toner ejection component is inserted, the guide part 51 first enters between the two conductive contacts until the arc-shaped piece 53 is fully inserted between the two conductive contacts. At this time, the printing device indicates that the toner cartridge has been installed. The design of the guide slope 511 is used to improve the smoothness of the guide part 51 inserting between the two conductive contacts. At the same time, the design of multiple arc-shaped pieces 53 also ensures the stability of the connection and positioning.

[0032] Furthermore, in this embodiment, the multiple guide portions 51 are irregularly distributed and can be disposed on the upper side or the lower side of the end of the arc-shaped piece 53. The upper and lower positions of the multiple guide portions 51 can be selected and arranged by those skilled in the art. In a specific embodiment, eight positioning portions 5 are provided, and the guide portions 51 on the eight positioning portions 5 are distributed in a clockwise direction in the positions of down, up, up, down, up, up, up, down, where up and down are respectively on the upper side or the lower side of the end of the arc-shaped piece 53 in a clockwise direction.

[0033] Furthermore, this embodiment also includes a plug-in post 6 and a positioning groove 7 formed on the end face of the annular body 1. The plug-in post 6 and the positioning groove 7 are used for plugging and positioning with the positioning structure of the printing device. In this embodiment, the plug-in post 6 and the annular body 1 are coaxially arranged, and the positioning groove 7 is a semi-waist-shaped groove. By adopting the design of the plug-in post 6 and the positioning groove 7, a more stable connection between the annular body 1 and the printing device can be achieved. Of course, the above-mentioned positioning structure is a groove and a protrusion formed at the connection port of the printing device. The groove is plugged and adapted to the plug-in post 6, and the protrusion is plugged and adapted to the positioning groove 7.

[0034] In some embodiments, the clamping structure 2 of this utility model includes a plurality of U-shaped grooves 21 spaced apart on the outer periphery of the annular body 1. Each U-shaped groove 21 forms a spring piece 22 on the annular body 1. The thickness of the spring piece 22 gradually increases along the insertion direction of the powder tube. That is, in this embodiment, by using a design of multiple spring pieces 22, multiple clamping arms are formed. When the open end of the powder tube is inserted into the interior of the annular body 1, the multiple spring pieces 22 clamp the outer wall of the powder tube, thereby improving the installation stability of the powder tube. Of course, in this embodiment, by adopting a structure with gradually increasing thickness of the spring piece 22, the purpose is to increase the resistance force received by the spring piece 22 and increase the deformation when the powder tube is inserted, thus increasing the reverse clamping force on the powder tube, thereby effectively improving the fixing stability of the powder tube.

[0035] It should be noted that, in this embodiment, the side of the annular body 1 is also formed with a side positioning plate 8, and the top of the annular body 1 is formed with an upper connecting bracket 9. The side positioning plate 8 is used to further improve the connection stability of the annular body 1. When the entire annular body 1 is installed at the installation port of the printing device, the upper connecting bracket 9 can be configured with a snap-fit ​​structure at the installation port to snap and fix the upper connecting bracket 9, so as to ensure the installation stability of the entire annular body 1.

[0036] In summary, this utility model has a guide portion 51 formed at the end of the arc-shaped piece 53. The purpose of the guide portion 51 is to insert into the connection slot of the printing device. A guide slope 511 is formed on the free end of the guide portion 51. The design of the guide slope 511 is used to improve the smoothness of the guide portion 51 inserting into the two conductive contacts. At the same time, the design of multiple arc-shaped pieces 53 also ensures the stability of the connection positioning. Furthermore, by adopting the design of setting multiple spring pieces 22 on the periphery of the annular body 1, it is possible to achieve a stable clamping of the toner cartridge after installation, thereby improving the installation stability of the toner cartridge.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
