Toner cartridge with anti-reversible powder supply opening in powder supply device

Abstract

The invention discloses a toner cartridge with an anti-reversible powder supply opening in a powder supply device. The toner cartridge structurally comprises a frame and a powder adding opening. An electricity distributing rod, magnetic bars, a carbon powder cavity, a photosensitive drum, a signal port, a connecting wire, a constant-temperature light absorption drum and the power supply opening are arranged in the frame, the powder adding opening and an upper end opening of the carbon powder cavity are integrated, and the two magnetic bars are arranged in the carbon powder cavity. According tothe toner cartridge, sealing heads and elastic pipes cooperate, elastic materials are adopted by the elastic pipes, a variable arc-shaped structure is formed through the gravity action of the sealingheads at one end, and carbon powder in the carbon powder cavity is output between the two sealing heads; when powder supply is stopped, the sealing heads are closed, and therefore the controllable anti-reversible powder supply opening is formed; external damp air can be prevented from entering the toner cartridge while biologies and insects get into the toner cartridge.

Description

technical field [0001] The invention relates to the field of toner powder, in particular to a toner cartridge provided with a reversible powder supply port in a powder supply device. Background technique [0002] The toner cartridge is one of the most important components in the electronic imaging device. It is the technical core of the electronic imaging device to complete the development. The toner cartridge is mainly used in copiers. The toner cartridge and the toner receiving box work together. The powder supply port It is normally open, and it is used for toner discharge during use. Since the interior of the copier is relatively higher than the outside room temperature, the normally open toner supply port is easy to attract some heat-seeking insects and organisms to run to the toner cartridge in the operating environment. Inside, the pollutants carried by insects and organisms seriously affect the quality of the internal toner; and when the normal opening returns to the...

Inside, the pollutants carried by insects and organisms seriously affect the quality of the internal toner; and when the normal opening returns to the south, the humid air from the outside easily circulates inside, causing the inside of the toner cartridge to be damp and cause toner agglomeration
