Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically a toner cartridge with an anti-tamper structure for the toner filling port. Background Technology

[0002] In the field of imaging equipment such as printers and copiers, toner cartridges are core consumables. Once the toner in the cartridge is depleted, it usually needs to be refilled through the toner refill port for reuse. In existing technology, toner cartridges are generally equipped with a removable plug at the toner refill port, and the surface of the plug is covered with an anti-tamper sticker to distinguish between original unopened toner cartridges and refilled toner cartridges.

[0003] However, this anti-tamper structure has obvious drawbacks: on the one hand, the anti-tamper sticker is cumbersome to apply and remove, requiring an additional labeling process during production, which increases manufacturing costs; on the other hand, the sticker is easily affected by environmental humidity and temperature, causing it to curl up or fall off, failing to effectively serve as an anti-tamper label, and may also contaminate the toner inlet due to residual adhesive, affecting the sealing of subsequent toner replenishment. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed toner cartridge with an anti-tamper structure for the toner filling port, which can solve the above-mentioned defects.

[0005] To achieve the above objectives, the utility model provides the following technical solution: it includes a toner cartridge body, a toner filling port is provided on one side of the toner cartridge body, a sealing plug is provided inside the port of the toner filling port, and a detachable anti-tamper baffle is provided at the front end of the port of the toner filling port.

[0006] Preferably, an arc-shaped groove is provided on the protective shell on one side of the drum body corresponding to the toner filling port.

[0007] Preferably, the anti-dismantling baffle is disposed in the arc-shaped groove, and the anti-dismantling baffle is disposed in the arc-shaped groove by several injection-molded connecting pieces.

[0008] The beneficial effects of adopting the above structure are: 1. This utility model replaces the traditional anti-tamper sticker by using injection-molded continuous connecting pieces to connect the anti-tamper baffle and the arc-shaped groove. This eliminates the labeling process in the production process, reduces labor and material costs, ensures stable connection strength, and prevents breakage without external prying. The anti-tamper marking effect is significant, solving the problem of stickers being easily affected by temperature and humidity and peeling off. It effectively distinguishes between original and refurbished toner cartridges, meeting the manufacturer's needs for consumable control.

[0009] 2. This utility model features a convenient disassembly operation through the anti-tamper baffle. Users can manually pry the edge to break the injection molding piece without professional skills. After the threshold breaks, the injection molding piece will leave obvious and irreversible damage marks and cannot be restored. This does not affect the subsequent powder injection operation and can intuitively indicate the opening status of the toner cartridge. It solves the drawbacks of traditional stickers that can be re-attached after being peeled off and are difficult to accurately identify. Attached Figure Description

[0011] Explanation of reference numerals in the attached figures: Toner cartridge body 1, toner filling port 2, sealing plug 3, anti-tamper baffle 4, arc-shaped groove 5, injection molded continuous piece 6, protective shell 7. Detailed Implementation

[0012] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0013] like Figure 1 - Figure 2 As shown, the present invention proposes a toner cartridge with a tamper-proof toner filling port structure, which includes a toner cartridge body 1, a toner filling port 2 provided on one side of the toner cartridge body 1, and a sealing plug 3 adapted to the inner side of the port of the toner filling port 2. The sealing plug 3 is made of elastic rubber material, which can form a seal protection for the toner filling port 2 to prevent toner leakage. On the protective shell 7 of the toner cartridge body 1 corresponding to the toner filling port 2, there is an inwardly recessed arc-shaped groove 5. The arc of the arc-shaped groove 5 is adapted to the outer contour of the toner filling port 2. Its groove depth is slightly greater than the thickness of the anti-tamper baffle 4. The front end of the toner filling port 2 is provided with an anti-tamper baffle 4. The anti-tamper baffle 4 is embedded in the arc-shaped groove 5. The edge of the anti-tamper baffle 4 is integrally injection molded with the inner wall of the arc-shaped groove 5 through three evenly distributed injection molding pieces 6. The thickness of the injection-molded connecting piece 6 is controlled between 0.3-0.5mm, which provides a certain connection strength and ensures that the tamper-proof baffle 4 maintains a stable sealing state when not subjected to external force. When toner needs to be replenished, the user only needs to pry the edge of the tamper-proof baffle 4 to break the injection-molded connecting piece 6 and quickly remove the tamper-proof baffle 4. The operation is convenient and the break marks are obvious, making it easy to distinguish between the original and the tampered state.

[0014] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
