  • Patent number: 11947281
    Abstract: A method for filling toner into a toner cartridge includes the steps of (a) taking a container, which accommodates the toner therein and has opposite first and second ends, and then forming a toner outlet at the first end, (b) sleeving the toner cartridge, which is provided at an end thereof with an opening, onto the container from the first end to the second end via the opening, (c) forming an air permeable hole at the second end, (d) withdrawing the container from the toner cartridge to enable the toner to leave the container via the toner outlet and stay inside the toner cartridge, and (e) sealing the opening of the toner cartridge by a cover. The method is simple and convenient to operate. With the method, the toner can be effectively filled without leakage and with reduced amount of residual toner.

  • Publication number: 20190113864
    Abstract: A toner cartridge includes a housing, a toner conveying shaft and a percussion device. The housing has a barrel portion, in which toners are contained, and a transmission portion rotatably disposed at an end of the barrel portion. The toner conveying shaft is rotatably disposed inside the barrel portion of the housing and drivenable by the transmission portion of the housing to rotate. The percussion device is configured to intermittently vibrate the barrel portion of the housing when the toner conveying shaft rotates. As such, when the percussion device intermittently vibrates the barrel portion of the housing, the toners attached on an inner wall surface of the barrel portion will be shaken down for being further discharged out of barrel portion, thereby reducing the residual amount of the toners that are contained in the barrel portion of the housing.

  • Patent number: 10191413
    Abstract: A toner cartridge for accommodating toners includes a barrel, a transmission member and a toner conveying shaft. The barrel is adapted for accommodating toners and provided at an end thereof with an opening. The transmission member is rotatably disposed at the end of the barrel. The toner conveying shaft is rotatably disposed inside the barrel and provided with a shaft portion and at least one scoop portion extending from the shaft portion in a way that the scoop portion conveys the toners from the barrel to the transmission member when the toner conveying shaft rotates relative to the barrel. As a result, the toners inside the barrel can be continuously discharged out via the scoop portion.

  • Publication number: 20180181024
    Abstract: A toner cartridge, which is adapted to be removably disposed in an electronic imaging device having a driving gear and at least one supporting member, includes an accommodating part, a gear ring, at least one rolling path portion, and a sensing protrusion. The accommodating part has an opening. The gear ring is provided on the periphery of the accommodating part for being engaged with the driving gear. The rolling path portion is provided on the periphery of the accommodating part and arc-shaped for being abutted on the supporting member in a point-contact manner. The sensing protrusion is provided on the periphery of the accommodating part and located between two ends of the rolling path portion. As a result, the toner cartridge can be positioned positively and prevented from deflection during rotation.

  • Patent number: 9996027
    Abstract: A toner cartridge includes a barrel having an opening, a transmission cap rotatably disposed to the barrel and blocking the opening, a sealing tape, and a toner conveying shaft rotatably disposed inside the barrel. The transmission cap has an outlet and an inner drive portion. The sealing tape has a first end sealing the outlet, and a second end fixedly mounted to the barrel. The toner conveying shaft has a driven portion. During a rotational period of the transmission cap, the first end of the sealing tape detaches from the outlet first, and then the inner drive portion abuts against the driven portion. When the transmission cap continuously rotates, the toner conveying shaft is driven by the transmission cap to rotate. As such, the transmission cap can drive the toner conveying shaft to synchronously rotate after the transmission cap brings the sealing tape to detach from the outlet.

  • Publication number: 20170168419
    Abstract: A toner cartridge includes a cylinder, a transmission member fixedly sleeved onto the cylinder, and a covering member sleeved onto the transmission member. The transmission member has a base pipe portion, a gear ring provided on the periphery of the base pipe portion and engaged with a driving gear of an electronic imaging device, and a protruded portion provided on the periphery of the base pipe portion. The peripheries of the protruded portion and the base pipe portion form a circumferential surface, so that a sensor in the electronic imaging device can sense positional variation of the circumferential surface during rotation of the transmission member. The sensor senses the pass of the protruded portion once in every revolution of the rotation of the transmission member. Therefore, the residual powder in the toner cartridge, which should be replaced according to an alarm of the electronic imaging device, is reduced.
