[0002] The toner cartridge, also called a photosensitive drum, is one of the important components of a printer, and is generally composed of an aluminum basic substrate and photosensitive material coated on the substrate. The common toner cartridges on the market are directly installed in the printer. When the toner cartridge rotates during work, the printing system sends the printing paper, and the printing paper is charged with an electric charge of the same polarity as the surface of the photosensitive drum but much stronger. Then the paper passes through the toner cartridge with toner, and the toner on the surface of the photosensitive drum is attracted to the printing paper, and an image is formed on the surface of the paper. The photosensitive drum is provided with a powder scraping plate for scraping the waste powder on the surface of the photosensitive drum, so that the waste powder falls into the waste powder bin.

[0003] However, the existing waste powder bin dismounting method has the following disadvantages: when dismounting the waste powder bin, the waste powder box is associated with other components, especially the position of the waste powder port, which makes dismounting very inconvenient. Generally, multiple buckle type or screw fastening methods are used to realize the installation and dismounting of the waste powder box, which is not convenient for waste powder treatment, cleaning and maintenance of the waste powder box, and affects the dismounting rate of the waste powder box.

[0020] The utility model will be further described in combination with the description and specific implementation of the drawings:

[0021] As Figures 1 to 5 The utility model discloses a selenium drum waste powder bin loading and unloading structure, including selenium drum shell 1, selenium drum component 2, waste powder bin 3, be provided with the powder inlet 31 at the top front side of waste powder bin 3, be provided with the guide groove 4 for limiting the movable track of waste powder bin 3 at the bottom of selenium drum shell 1, the elastic structure 5 that can elastically press from the front side of waste powder bin 3, the locking structure 6 for locking or unlocking the installation state of waste powder bin 3, the front end of waste powder bin 3 is inclined and exposes the powder inlet 31 with the turning part 32 being arranged at the front side of guide groove 4. The selenium drum component includes each component of the selenium drum, for example, the photosensitive drum, the magnetic roller, the powder bin, the gear set and the like, and the waste powder outlet of the selenium drum component is connected to the air inlet. The waste powder will directly fall into the waste powder bin. When the waste powder bin is installed, the locking structure is in the locked state, and the elastic structure is in the elastic compression state. When the waste powder bin needs to be disassembled, the locking structure is unlocked, and the elastic structure will pop out the waste powder bin to the front side. At the same time, the guide groove will limit the movable track of the popped-out waste powder bin. Under the action of the turning part, the waste powder bin will first pop out linearly to the front side. Then, under the action of the hand, the front end can be inclined downward to expose the powder inlet, so as to facilitate the waste powder treatment, the cleaning and maintenance of the waste powder box.

[0022] The utility model discloses the waste powder bin 3 left and right sides are provided with at least two guide blocks 33 and are arranged in the guide groove 4 and limit the activity. The guide block 33 at the front side can slide into the turning part 32 to make the front end of waste powder bin 3 be inclined. The guide blocks are in front of and behind the left and right sides of the waste powder bin. The guide block at the front side can fall into the turning part.

[0023] The utility model discloses the elastic structure 5 includes setting the base plate 51 of selenium drum shell 1 left and right two sides, be provided with the connecting seat 52 at the lower side of base plate 51, the arc bending rod 53 is hinged on connecting seat 52, be provided with torsion spring 54 between arc bending rod 53 and connecting seat 52, be provided with the top circle 55 for pressing the rear end of waste powder bin 3 at the lower end of arc bending rod 53, be provided with connecting rod 56 between two arc bending rods 53. Under the action of torsion spring, the arc bending rod will keep the force of rotating forward all the time. The function of the top circle is to facilitate the installation of the waste powder bin by pushing in when the waste powder bin is installed. When installed, the rear end of the waste powder bin first contacts the top circle, allowing the arc bending rod to rotate backward and the torsion spring to compress. The function of the connecting rod is to allow the two top circles on the left and right sides to move synchronously, so that the elastic force on the left and right sides of the rear end of the waste powder bin is the same.

[0024] In this invention, the substrate 51 is provided with several adjustment slots 7, which are connected to the bottom rear side of the drum housing 1 by screws. The substrate is designed to be removable from the bottom of the drum housing, and the adjustment slots allow the substrate to be adjusted in position at the bottom of the drum housing by loosening the screws. This adjustment is used when the waste toner compartment is not properly positioned after installation.

[0025] The locking structure 6 described in this invention includes sliding grooves 61 located on the left and right sides of the bottom front of the drum housing 1. A spring 62 is located at the bottom of the sliding groove 61, and a pressing block 63 is located at the top of the spring 62. A rotatable rotating rod 64 is located on the upper side of the pressing block 63. A locking rod 65, which abuts against the front of the waste toner compartment 3, is fixed between the outer ends of the two rotating rods 64. When the waste toner compartment is installed, the rotating rod is rotated to the front, and the locking rod abuts against the front wall of the waste toner compartment. Under the limiting action of the guide groove and the elastic force of the elastic structure, the locking rod limits the front end of the waste toner compartment, thus achieving a secure installation. When removing the waste toner compartment, simply pry the locking rod downwards by hand; the front end of the waste toner compartment loses its limiting action, and the elastic force of the elastic structure will push it forward. The combination of the slide, spring, and top pressure block allows the rotating rod to move downwards under the force of a human hand. In use, when the guide block slides into the turning part and presses down on the front end of the waste powder bin, the front end of the waste powder bin can tilt downwards, exposing the powder inlet. Since the locking rod is located on the lower side of the waste powder bin at this time, the top pressure block moves downwards and the spring contracts.

[0026] In this invention, the waste powder bin 3 has a rounded corner 34 on its lower front end, allowing the locking rod 64 to slide on it. The purpose of the rounded corner is to allow the locking rod to more smoothly achieve the limiting of the front end of the waste powder bin when rotating from the lower side to the front side; and to more smoothly disengage the limiting of the front end of the waste powder bin when rotating from the front side to the lower side, so that the waste powder bin pops out.

[0027] The locking rod 64 described in this invention has its outer wall covered with soft rubber. Because the waste powder bin has a forward-splashing force during installation, the rounded corners of the locking rod and the waste powder bin are less prone to scratching after being covered with soft rubber, thus preventing damage to the waste powder bin.
