Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, and in particular to a toner cartridge with added powder to prevent spillage. Background Technology

[0002] Toner cartridges designed to prevent spillage during refilling achieve precise control of toner during the refilling process through structural design, material application, and functional optimization, avoiding or reducing toner spillage. Through spill-prevention designs (such as sealed refill ports and anti-static adsorption structures), the amount of toner dust generated during refilling is reduced by more than 80%, preventing toner from drifting into the air and forming dust particles (mostly 1-5μm in diameter), thus preventing pollution of office desks, equipment interiors, and indoor air.

[0003] In existing technologies, toner cartridges designed to prevent loosening are prone to spilling to the outside of the device during the toner refilling process. If toner particles are inhaled, they may accumulate in the lungs, causing respiratory diseases such as pharyngitis and bronchitis. Furthermore, some toners contain chemicals such as resins and colorants, and long-term exposure may pose risks of allergies or toxicity. Therefore, this paper proposes a toner cartridge designed to prevent spillage during refilling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a toner cartridge for preventing powder spillage, comprising: a toner cartridge body, a feed inlet fixedly connected to one end of the top of the toner cartridge body, a funnel connected to the end of the feed inlet away from the toner cartridge body, four sets of connecting rods fixedly connected to the top of the toner cartridge body, a mounting plate fixedly connected to the end of the four sets of connecting rods away from the toner cartridge body, a circular block rotatably connected to the center of the top of the mounting plate, multiple sets of sliders sliding around the periphery of the circular block, and a clamping block fixedly connected to one side of each set of sliders.

[0005] As an improvement to the above technical solution, a rubber sealing ring is provided at the junction of the funnel and the feed inlet, and double-sided adhesive is provided on the side of the rubber sealing ring near the feed inlet, with one side of the double-sided adhesive adhering to the outer wall of the feed inlet.

[0006] As an improvement to the above technical solution, a handle is fixedly connected to one side of the circular block.

[0007] As an improvement to the above technical solution, multiple sets of sliding grooves are formed on the periphery of the circular block, and horizontal bars slide on both sides of the inner wall of the multiple sets of sliding grooves. A vertical shaft is fixedly connected to the middle of the horizontal bar, and one end of the vertical shaft is connected to the bottom end of the slider.

[0008] As an improvement to the above technical solution, a soft pad is provided on the side of the clamping block away from the slider, and screws are provided around the soft pad, with one end of each screw connected to one side of the clamping block.

[0009] As an improvement to the above technical solution, limiting grooves are provided on both sides of the inner wall of the multiple sets of sliding grooves, and the two ends of the crossbar slide inside the limiting grooves.

[0010] The beneficial effects of this utility model are as follows: Four sets of connecting rods are fixed to the top of the drum body, ensuring the relative position of the mounting plate and the feed inlet is fixed, facilitating precise positioning of the clamping block after the funnel is connected. The four sets of connecting rods are evenly distributed, distributing the weight of the mounting plate and the clamping force to the drum body, avoiding localized deformation. The circular block is rotatably connected to the mounting plate via bearings, allowing for [degree of rotation].

[0011] The rotating mechanism allows for easy adjustment of the clamping block's position, accommodating funnels inserted at different angles. As the slider slides around the circular block, it drives the clamping block to move synchronously. The centripetal movement of multiple sets of clamping blocks clamps the outer wall of the funnel, keeping the funnel stationary. The carbon powder flows smoothly into the feed inlet along the funnel, preventing powder spillage caused by shaking the funnel while holding it. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] See appendix Figure 1-4 As shown, to solve the above problems, a toner cartridge with anti-spillage function is provided, comprising: a toner cartridge body 1, a feed inlet 8 fixedly connected to one end of the top of the toner cartridge body 1, a funnel 6 connected to the end of the feed inlet 8 away from the toner cartridge body 1, four sets of connecting rods 14 fixedly connected to the top of the toner cartridge body 1, a mounting plate 2 fixedly connected to the end of the four sets of connecting rods 14 away from the toner cartridge body 1, a circular block 3 rotatably connected to the top center of the mounting plate 2, multiple sets of sliders 11 sliding around the periphery of the circular block 3, and a clamping block 12 fixedly connected to one side of each set of sliders 11.

[0023] The funnel 6 is directly connected to the feed inlet 8 to reduce powder leakage at the interface. The mounting plate 2 serves as the base platform for the clamping mechanism and is fixed to the top of the drum body 1 by four sets of connecting rods 14, ensuring that the relative position of the mounting plate 2 and the feed inlet 8 is fixed, facilitating precise positioning of the clamping block 12 after the funnel 6 is connected. The four sets of connecting rods 14 are evenly distributed to distribute the weight and clamping force of the mounting plate 2 to the drum body 1, avoiding localized deformation. The circular block 3 is rotatably connected to the mounting plate 2 via bearings and can rotate 360°, facilitating adjustment of the position of the clamping block 12. The funnel 6 is designed to accommodate different insertion angles. When the slider 11 slides around the circular block 3, it drives the clamping block 12 to move synchronously. The centripetal movement of multiple sets of clamping blocks 12 clamps the outer wall of the funnel 6, keeping the funnel 6 stationary. The toner flows smoothly into the feed inlet 8 along the funnel 6, avoiding powder spillage caused by shaking the funnel 6. If toner particles are inhaled by the operator, they may be deposited in the lungs, causing respiratory diseases such as pharyngitis and bronchitis. Some toners contain chemicals such as resin and colorants, and long-term contact may pose a risk of allergies or toxicity.

[0024] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a rubber sealing ring 7 is provided at the junction of the funnel 6 and the feed inlet 8. Double-sided adhesive is provided on the side of the rubber sealing ring 7 near the feed inlet 8, and one side of the double-sided adhesive is attached to the outer wall of the feed inlet 8.

[0025] By using double-sided tape to attach the rubber sealing ring 7 to the outer wall of the feed inlet 8, it is ensured that the rubber sealing ring 7 will not fall off or shift during use. In particular, it prevents the rubber sealing ring 7 from becoming misaligned due to the insertion and removal of the funnel 6 when adding powder. The elastic compression of the rubber sealing ring 7 fills the gap at the interface and prevents the toner from leaking out.

[0026] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a handle 4 is fixedly connected to one side of the round block 3.

[0027] By using a handle 4 to be fixedly connected to a circular block 3, when the handle 4 is held and rotated clockwise and counterclockwise, the circular block 3 rotates synchronously.

[0028] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, multiple sets of sliding grooves 5 are opened on the periphery of the circular block 3, and horizontal bars 10 slide on both sides of the inner wall of the multiple sets of sliding grooves 5. A vertical shaft 9 is fixedly connected in the middle of the horizontal bar 10, and one end of the vertical shaft 9 is connected to the bottom end of the slider 11.

[0029] The grooves 5 are evenly distributed along the periphery of the circular block 3, providing a track for the sliding of the slider 11, ensuring the stability and symmetry of the clamping action, so that the slider 11 can slide along the periphery of the circular block 3 in the grooves 5, driving the clamping block 12 closer to or away from the center, thereby adapting to funnels 6 or powder adding tools of different diameters and enhancing the versatility of the device.

[0030] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a soft pad 13 is provided on the side of the clamping block 12 away from the slider 11, and screws 15 are provided around the soft pad 13. One end of the screws 15 is connected to one side of the clamping block 12.

[0031] The soft pad 13 is usually made of silicone, EVA foam or nitrile rubber, which has the characteristics of low hardness and high elasticity. When clamping the funnel 6, it avoids direct contact between the metal clamping block 12 and the funnel 6, preventing the clamping force from causing the funnel 6 to deform or crack. The surface of the soft pad 13 is designed with anti-slip texture, which can improve the clamping force compared with the metal clamping block 12, while absorbing the slight vibration during powder addition, preventing the funnel 6 from spilling toner due to shaking. After the soft pad 13 is worn, it can be replaced by simply unscrewing the screw 15, without disassembling the entire clamping mechanism.

[0032] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, limit grooves are provided on both sides of the inner wall of multiple sets of slide grooves 5, and the two ends of the crossbar 10 slide inside the limit grooves.

[0033] When the two ends of the crossbar 10 are embedded in the limiting groove, the limiting groove constrains the movement of the crossbar 10, which can prevent the clamping block 12 from being accidentally loosened. Turning the handle 4 causes the round block 3 to rotate, and the crossbar 10 slides along the groove 5 in the circumference of the limiting groove, pushing the slider 11 to move radially. The limiting groove ensures that the movement trajectory of the slider 11 is perpendicular to the axis of the funnel 6, and the force in all directions is consistent when clamping, so as to avoid the funnel 6 from tilting.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
