Through the technical scheme, the boss is arranged on the felt platform of the powder bin, so that the contact part of the felt and the scraping blade is jacked up by the boss, the felt deforms under the compression of the scraping blade and the felt platform, is more attached to the surface of the scraping blade and forms an upward acting force on the scraping blade, better sealing performance is provided, and carbon powder is prevented from leaking from a gap between the felt and the scraping blade.
As a further improvement of the utility model, the boss is obtuse triangle along felt platform length direction's cross-sectional shape to the obtuse angle is kept away from the felt platform and is set up on the felt platform.
As a further improvement of the utility model, one side of the boss close to the lower part of the felt platform is parallel to the side surface of the scraping sheet.
As a further improvement of the utility model, the obtuse angle of the obtuse triangle is processed by rounding.
As a further improvement of the utility model, the height of the boss is 0.5mm to 1.0 mm.
As a further improvement of the utility model, the height of the boss is 0.8 mm.
As a further improvement, the circular arc is smoothly connected between the boss and the felt platform.

(specific embodiments) in all cases
The following description will further describe a specific embodiment of the present invention with reference to the accompanying drawings, for convenience of description, the present application may define the directions of upper, lower, left, right, front, rear, etc., and is intended to clearly describe the relative position relationship of the structure, and is not intended to limit the actual directions of the product during the production, use, sale, etc.; in fig. 2 and 5, the direction indicated by the arrow is upward. The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
referring to fig. 1, 2 and 3, the present embodiment provides a toner cartridge for a printer, which includes a toner hopper cover 1, a toner hopper 2, a felt 3, a sponge strip 4 and a scraping blade 5.
Referring to fig. 4, 5 and 6, the two ends of the powder bin 2 are provided with felt platforms 21, the felt platforms 21 are concave arc surfaces, the felt platforms 21 are respectively provided with a boss 211 with an obtuse triangle cross section along the length direction of the felt platform, the boss 211 is arranged on the felt platform 21 at a projection position which is attached to the scraper 5 of the felt 3 and far away from the felt platform 21 at an obtuse angle, the obtuse angle of the obtuse triangle is processed by rounding, and the boss 211 is smoothly connected with the felt platform 21 through an arc. The height of the protrusion of the boss 211 relative to the felt platform 21 is 0.8mm (for clearly showing the boss, a reference line a in fig. 5 is an arc line of the original felt platform), and one surface of the boss 211 close to the lower part of the felt platform 21 is parallel to the side surface of the scraper 5. The powder bin 2 is further provided with a sponge strip mounting seat 22, and the sponge strip mounting seat 22 is arranged below the felt platform 21 and connected with the felt platform 21. As other possible implementations, the height of the boss protrusion is other values between 0.5mm and 1.0mm, inclusive.
The two same felts 3 are rectangular felts with the thickness of 3mm, the width of the felts is the same as that of the felt platform 21, the length of the felts is the same as that of the surface of the felt platform 21, and the felts are stuck on the felt platform 21. The sponge strip 4 is transversely installed on the sponge strip installation seat 22, and the upper end of the sponge strip 4 is connected with the lower end of the felt 3.
The powder bin cover 1 is welded on the powder bin 2 and forms a closed container with the powder bin 2. The scraping blade 5 is arranged on the powder bin cover 1. When the powder bin cover 1 is arranged on the powder bin 2, the lower end of the scraping blade 5 is abutted against the felt 3, one side surface of the scraping blade 5 is attached to the felt 3, and the attaching part is the position of the boss 211.
When the assembly of the printer toner cartridge is completed, the contact part of the felt 3 and the scraping blade 5 is jacked up by the boss 211, the felt 3 is pressed and deformed under the compression of the scraping blade 5 and the felt platform 21, the felt 5 is more attached to the surface of the scraping blade and forms an upward acting force on the scraping blade 5, so that the side surface of the scraping blade 5 is more closely attached to the felt 3, the lower end of the scraping blade 5 abuts against the felt 3, the lower end of the felt 3 is connected with the sponge strip 4, and a good sealing working space is provided for the working area of the toner hopper 2.
