Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 2 to 6, the toner cartridge in the present embodiment includes a toner hopper 1 and a pull strip 2.

The powder bin 1 is internally provided with a containing cavity for containing carbon powder, and the overall shape of the powder bin 1 is specifically set according to needs. The powder hopper 1 is generally elongated as a whole. The powder hopper 1 includes a first side wall, a second side wall, and end walls at both ends. The first side wall is located at the front side of the second side wall, the first side wall extends from top to bottom, the second side wall extends downwards and forwards, the lower part of the second side wall forms a bottom wall 102 of the powder bin 1, the lower edge of the first side wall which is used as the front side wall 101 of the powder bin 1 is located above the bottom wall 102 of the powder bin 1, and thus a powder outlet is formed between the front side wall 101 and the bottom wall 102 of the powder bin 1.

The brace 2 is covered on the powder outlet, an outlet for the brace 2 to penetrate out is further formed in the powder bin 1, specifically, the outlet is located in the end wall of the powder bin 1, a first sealing element 5 and a second sealing element 6 are arranged in the outlet, the first sealing element 5 and the second sealing element 6 are respectively arranged on two sides of the brace 2, and the first sealing element 5 and the second sealing element 6 are made of materials with certain elasticity. The first sealing element 5 and the second sealing element 6 are in a pressing state and are embedded in the outlet in an interference manner. The first sealing element 5 and the second sealing element 6 can realize sealing of the outlet position and prevent powder leakage. Residual ink powder on the brace 2 can be removed, and the influence on printing caused by leakage of the residual ink powder on the brace 2 is avoided.

The bottom wall 102 of the powder bin 1 is bent and formed with a mounting surface 12 for fixing the lower edge of the pull strip 2, and the mounting surface 12 extends towards the lower edge of the front side wall 101 of the powder bin 1. The lower part of the front side wall 101 of the powder bin 1 extends downwards in a plane, the upper edge of the brace 2 is bent to form a bent part 21 and fixed on the lower part of the front side wall 101 of the powder bin 1, and the bending angle of the brace 2 is matched with the plane of the lower part of the front side surface and the mounting surface 12 on the bottom wall 102.

In order to conveniently realize the fixed installation of the brace 2, the edge of the brace 2 used for covering the powder outlet is provided with an adhesive layer 3 corresponding to the powder outlet, the adhesive layer 3 can be made of various materials with adhesive effect, such as a double-faced adhesive layer 41, so that the edge of the brace 2 is adhered to the edge of the powder outlet through the adhesive layer 3, namely, the upper edge of the brace 2 is adhered to the lower edge of the front side wall 101 through the adhesive layer 3, the lower edge of the brace 2 is adhered to the installation surface 12 of the bottom wall 102 through the adhesive layer 3, the tail end of the brace 2 is adhered to the connection surface of the front side wall 101 and the bottom wall 102 through the adhesive layer 3, and then the front end of the brace 2 is folded and then passes through the outlet to the outside of the powder bin 1.

For the convenience of tearing and pulling out brace 2, be equipped with the line of cut corresponding to the part of peeling off on the brace 2, the line of cut of 2 both sides of brace is half tangent line, avoids the part that needs to peel off among the brace 2 to drop, can effectively reduce the operating force simultaneously, and the line of cut of 2 both sides of brace is identical with meal outlet front side edge, rear side edge respectively. The tangent line at the tail end of the brace 2 is a full tangent line 22, so that the pulling force required when the brace 2 is pulled out is reduced. The full tangent line 22 at the end of the brace 2 in this embodiment is trapezoidal, and the full tangent line 22 in this embodiment is isosceles trapezoidal, so that the connection length of the tail end of the brace 2 can be reduced to reduce the pulling force required during pulling. When the pull strip 2 is pulled to the inclined edge of the isosceles trapezoid, the pull force required for pulling the pull strip 2 along the inclined edge to the overall exit is reduced to 3/5 compared with the pull force required without the full tangent 22. In the present embodiment, as shown in fig. 6, the three cutting marks of the full-cut line 22 intersect with each other, and the uncut image at the intersection of the cutting marks is prevented.

In order to place leaked powder, protective plates 4 covering the pull strip 2 are further arranged at the two ends of the powder outlet. Protection sheet 4 passes through glue film 41 to be fixed on brace 2 that is located play powder mouth both ends, and this protection sheet 4 can effectively seal play powder mouth both ends position department, and the part that brace 2 failed to cover completely and the full tangent line 22 position in brace 2 can effectively prevent through protection sheet 4 that the air outlet both ends position is in the powder leakage condition based on brace 2 structure.

This toner cartridge has changed the structure of powder storehouse 1 preceding lateral wall 101 for preceding lateral wall 101 is plane downwardly extending, has changed the structure that needs buckle powder storehouse 1 preceding lateral wall 101 and set up among the prior art, so not only increased the area of powder outlet, increased the confession powder volume of powder outlet. Meanwhile, a carbon powder storage gap is not formed between the scraper and the scraper, the phenomenon that carbon powder is agglomerated in the gap is avoided, and the circulation of the carbon powder is improved. And the bending structure of the brace 2 can realize the fixed installation through simple change. And can effectively reduce the operation pulling force of brace 2 based on the line of cut on brace 2, also difficultly when brace 2 pulls out, avoided the condition of pulling out the difficulty.

The utility model discloses still relate to a printer, include like aforementioned toner cartridge, still including setting up at the scraper 8 of toner outlet department and corresponding to the toner outlet and set up at the developer roll 7 of toner outlet front side, scraper 8 supports on developer roll 7. Before the printer works, a user pulls the part, exposed outside the powder bin 1, of the pull strip 2 to pull out the pull strip 2, the powder outlet is sealed, and the powder bin 1 is communicated with the developing roller 7 through the powder outlet. The extending direction of the scraper 8 is consistent with the extending direction of the front side wall 101 of the powder bin 1, so that the situation of toner agglomeration caused by toner accumulation can not occur, and the printing effect is improved.

Directional terms such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", and the like are used in the description and claims of the present invention to describe various example structural portions and elements of the present invention, but these terms are used herein for convenience of description only and are determined based on example orientations shown in the drawings. Because the disclosed embodiments of the present invention may be oriented in different directions, the directional terms are used for descriptive purposes and are not to be construed as limiting, e.g., "upper" and "lower" are not necessarily limited to directions opposite or coincident with the direction of gravity.
