Description

Technical Field

[0001] The utility model relates to the technical field of photocopier powder boxes, in particular to a photocopier powder box with a leak-proof structure. Background Art

[0002] The photocopier is designed based on the principles of photoconductivity of semiconductors and frictional electricity generation between substances. The inventor Carlson cleverly combined these seemingly unrelated principles and developed a new technology that has profoundly influenced modern civilization. Although the photocopier is still being improved year by year, the basic steps are still similar to Carlson's design from forty years ago. The protagonist of the photocopier is the photoconductor. Under the irradiation of light, the photoconductor changes from an insulator to a conductor. It is a light-sensitive object. In the dark, its resistance is very large and it will not conduct electricity. After being exposed to light, the free electrons in the molecules increase, the resistance decreases, and it can conduct electricity. Inorganic substances such as selenium, arsenic, tellurium and their alloys are all photoconductors. Modern selenium is used to replace the sulfur originally used by Carlson.

[0003] A toner cartridge for a photocopier usually includes a cartridge body, on which a powder storage bin, a waste toner bin, a photosensitive drum, a magnetic roller, etc. are provided. In existing toner cartridges for photocopiers, the powder feeding hole of the powder storage bin is usually located on the side wall of the powder storage bin and is blocked by a side shell on the cartridge body. After the powder in the powder storage bin is used up, it is often difficult to replenish the powder through the powder feeding hole. If powder needs to be replenished, the cartridge body needs to be disassembled to expose the powder feeding hole for replenishment. However, it is difficult for most ordinary users to complete the disassembly and assembly of the cartridge body independently, and other components on the toner cartridge for the photocopier may be damaged during the disassembly and assembly process, which greatly increases the user's cost of use. The vibration generated when the toner cartridge for a photocopier is used for a long time may easily loosen the cover of the feed port, thereby easily causing the powder inside to leak. Therefore, in response to the above problem, a toner cartridge for a photocopier with a leak-proof structure is proposed.

[0004] The existing patent (publication number: CN 215219429 U) discloses a photocopier powder box with a leak-proof structure, including a box body, which is provided with a sealing cover, a rubber ring, a first pull ring, a sealing gasket, an extrusion plug and a second pull ring. Since a feed port is provided at the front end of the powder storage bin, the extrusion plug and the sealing cover can be taken out in sequence by pulling the second pull ring and the first pull ring, so that powder can be added from the feed port without disassembling the box body, thereby improving the use effect. At the same time, the feed port is squeezed by the rubber ring. Since the shape of the rubber ring is a hollow cone and the shape of the extrusion plug is a solid cone, the rubber ring is sealed. By pressing the extrusion plug, the extrusion plug slides inside the rubber ring, thereby further improving the sealing effect to prevent powder leakage. By providing a card block, The extrusion plate, the limiting ring, the adjusting ring, the gear and the positioning screw are connected together by the limiting ring and the adjusting ring. The two extrusion plates are made to slide synchronously by aligning the card block with the card slot at the front end of the powder storage bin and sliding it. The adjusting ring is rotated to make the gear mesh with the tooth block inside the adjusting ring and descend, so that the gear touches the positioning screw. The adjusting ring is rotated to make the four gears rotate together, so that the gear squeezes the extrusion plate, and the extrusion plate squeezes the extrusion plug, so that the extrusion plug applies uniform pressure to the rubber ring to prevent the extrusion plug from tilting and causing powder leakage. At the same time, the extrusion plug is fixed to prevent the extrusion plug from falling off due to vibration caused by long-term use of the box body, thereby improving the fixing effect.

[0005] However, the above technical solution still has certain defects. When the cover is disassembled, the gear is meshed with the tooth block inside the adjusting ring by rotating the adjusting ring, so that the extrusion plug applies uniform pressure to the rubber ring to prevent the extrusion plug from tilting and causing powder leakage. At the same time, the extrusion plug must be fixed to complete the fixation, which is inefficient. Therefore, a photocopier toner cartridge with a leak-proof structure is proposed.
