Abstract: A toner cartridge is provided. The toner cartridge can be removably mounted on an imaging device. The toner cartridge includes a housing with a toner storage; a toner outlet aligned with a toner inlet on the imaging device; and a switch assembly disposed between the toner outlet and the toner inlet and controlling toner in the toner cartridge to flow from the toner outlet into the toner inlet. The switch assembly slides between a first position to open the toner outlet and a second position to close the toner outlet.

Abstract: A back massaging and cleaning device has a main body having a back plate, a first clamping block connected at right angles to a first end of the back plate, and a second clamping block connected at right angles to a second end of the back plate. A connection mechanism connects the back plate to a wall of a shower or bathroom. A back massaging and cleaning rod has a fixed rod and a movable roller wheel provided on the fixed rod, the fixed rod having a first end that extends through a hole of the first clamping block, and a second end that is seated in a groove of the second clamping block. The roller wheel has an irregularly shaped cylindrical body externally made from a back cleaning material and internally made from a massaging material.

Abstract: A driving assembly is provided for a processing cartridge capable of being detachably installed in an electronic imaging device. The driving assembly includes a power receiving unit and a power transfer unit. The power receiving unit is configured for receiving a rotational driving force from a driving mechanism of the electronic imaging device; and the power transfer unit is coupled to the power receiving unit for receiving the rotational driving force from the power receiving unit. The power receiving unit remains constantly inclined with respect to a rotation axis of the power transfer unit, and has an initial position and a displaced position; the power receiving unit moves from the initial position to the displaced position when an external force is applied; and the receiving unit returns to the initial position from the displaced position when the external force is withdrawn.

Abstract: The present invention relates to a rotational force driving assembly and a process cartridge used for being engaged with a rotational force driving head inside an electrophotographic image forming device. The rotational force driving assembly can comprise a hub, a rotational force receiving component, a side plate, and an axis offset adjusting mechanism. When the axis offset adjusting mechanism is not subjected to external force, the axis offset adjusting mechanism enables the axis of the rotational force receiving component to be parallel and offset to the axis of the hub. When the axis offset adjusting mechanism is subjected to external force, the rotational force receiving component extends out to be engaged with the rotational force driving head.
