The utility model has the following technical effects:

the carbon powder replenishing bottle of the utility model stores the carbon powder for replenishing the selenium drum in the elastic bottle body. Meanwhile, a neck pipe is also arranged on the carbon powder supplement bottle, and a bottle mouth is arranged on the neck pipe. The neck pipe is used for being connected with a corresponding connecting hole arranged on the powder bin of the toner cartridge to form a closed toner replenishing channel, and toner can enter the powder bin of the toner cartridge through the toner replenishing channel to realize the process of replenishing toner to the toner cartridge. After the toner cartridge is assembled to the printing equipment, the toner cartridge can be supplemented only by connecting the neck pipe of the toner supplementing bottle with the corresponding connecting hole on the toner cartridge powder bin without taking the toner cartridge out of the printing equipment when the toner cartridge needs to be supplemented with toner because the corresponding connecting hole is arranged on the surface of the toner cartridge facing the toner cartridge assembling port of the printing equipment.

The inner end cover of the bottle mouth arranged on the bottle mouth covers the bottle mouth, and the outer end cover of the bottle mouth is arranged outside the inner end cover of the bottle mouth. A first powder through hole and a second powder through hole are respectively arranged on the inner end cover and the outer end cover of the bottle mouth. The outer end cover connecting structure enables the outer end cover of the bottle mouth to rotate relative to the inner end cover of the bottle mouth, and the rotation enables the first powder through hole and the second powder through hole to be switched between a conduction state and a non-conduction state. These two states also correspond to the conducting and non-conducting states of the toner replenishment path, respectively. When the first powder through hole and the second powder through hole are communicated, the carbon powder in the carbon powder supplementing bottle can supplement the carbon powder to the powder bin of the toner cartridge through the communicated carbon powder supplementing channel; when the first powder through hole and the second powder through hole are in a non-conducting state, the carbon powder in the carbon powder supplement bottle is isolated from the outside, and the carbon powder is prevented from being adversely affected by the external environment.

And the first powder through hole and the second powder through hole are in a non-conducting state, so that the bottle opening can be sealed, and carbon powder leakage is avoided. And after the carbon powder replenishing bottle is communicated with the corresponding connecting hole on the toner cartridge bin, the first toner through hole and the second toner through hole are communicated by rotating the outer end cover of the bottle mouth, so that carbon powder replenishing is carried out. Therefore, in the process, the carbon powder is not required to be exposed in the air, namely, the carbon powder replenishing process is a closed process, so that the environmental pollution is avoided.

In addition, after the carbon powder replenishing bottle is connected with the powder bin of the toner cartridge, the carbon powder in the carbon powder replenishing bottle cannot be completely and automatically flowed into the powder bin of the toner cartridge through the carbon powder replenishing channel, and if the carbon powder is promoted to flow into the powder bin of the toner cartridge through manual modes such as vibration, dumping and the like, the carbon powder replenishing channel is easily in an unsealed state, so that the carbon powder is leaked. The carbon powder supplementing bottle provided by the utility model is provided with the elastic bottle body, and the air pressure in the elastic bottle body is larger than the air pressure in the powder bin of the toner cartridge by extruding the elastic bottle body, so that the residual carbon powder is driven to enter the powder bin by pressure difference.

Two movable limiting structures with a certain distance are arranged on the outer side of the powder bin interface buckling wall 102: a movable limit structure 204 and a movable limit structure 209. The movable limiting structure is a limiting block protruding out of the outer wall of the powder bin interface buckling wall 102.

When the outer end cap 208 of the bottle mouth is rotated, at least two positions can be reached through the rotation: a first position and a second position. When the bottle mouth outer end cover 208 rotates to reach the first position, the first powder through hole 202 and the second powder through hole 207 are in a conducting state, which is shown in fig. 3. When the bottle mouth outer end cap 208 is rotated to reach the second position, the first powder passing hole 202 and the second powder passing hole 207 are in a non-conducting state (i.e., a closed state), which is shown in fig. 4.

The location of the opening 301 in the powder receptacle interface closure wall and the annular sealing sponge 206 can also be seen more clearly in fig. 4.

FIGS. 5 and 6 show the use of the toner refill bottle of the present invention. The technical solution of the present invention will be further described below with reference to the use process.

After the carbon powder of the toner cartridge 504 assembled in the printing device is consumed, the toner cartridge inlet of the printing device is opened, and the corresponding connecting hole 502 arranged on the surface facing the toner cartridge inlet of the toner cartridge 504 is further opened. The corresponding connection hole 502 is communicated with the powder bin of the toner cartridge 504. A locking pin 503 is provided near the corresponding connection hole 502. The locking pin 503 is a pin. The opening of the toner replenishing bottle 501 (i.e. the embodiment of the toner replenishing bottle shown in fig. 1) is directed to the corresponding connecting hole 502, and the first powder passing hole 202 and the second powder passing hole 207 are in a non-conducting state. It is also necessary to align the openings 301 in the powder hopper interface snap walls 102 with the snap pins 503 and then insert the neck portion of the toner refill bottle 501 into the corresponding connection holes 502. The corresponding connection hole 502 has a protruding circular hole wall, the circular hole wall is inserted into the gap between the powder bin interface buckling wall 102 and the neck tube buckling wall 205 to ensure that the toner replenishing bottle 501 can be stably connected with the corresponding connection hole 502, meanwhile, the clamping pin 503 is clamped into the opening 301, the flange at the top of the circular hole wall is abutted against the annular sealing sponge cushion 206, and the assembling state of the toner replenishing bottle 501 as shown in fig. 6 is realized. At this time, the elastic bottle body 101 can be rotated by using the axis of the neck tube 212 as a rotating shaft, and the fastening pin 503 fastens the fastening wall 102 of the powder bin port, i.e. the outer end cap 208 of the bottle mouth is kept still, and the inner end cap 211 of the bottle mouth rotates along with the elastic bottle body 101, so that the first powder through hole 202 is communicated with the second powder through hole 207, and under the action of gravity, carbon powder can be supplemented from the carbon powder supplementing bottle 501 to the powder bin of the toner cartridge 504. If the process of the carbon powder entering the powder bin is not very smooth, the elastic bottle body 101 can be extruded, so that the air pressure in the elastic bottle body 101 is larger than the air pressure in the powder bin, and the carbon powder is driven to enter the powder bin smoothly. During the process of pressing the elastic bottle body 101, the gas overflows the joint space formed by the powdered carbon replenishing bottle 501 and the powder bin of the toner cartridge 504. When gas overflows through the connection of the carbon powder supplementing bottle 501 and the corresponding connection hole 502, the gas can be discharged through the air holes of the sponge cushion due to the arrangement of the annular sealing sponge cushion 206, but the carbon powder with larger particles can be intercepted by the annular sealing sponge cushion 206, so that the overflow of the carbon powder is avoided.

It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereby, and the present invention may be modified in materials and structures, or replaced with technical equivalents, in the constructions of the above-mentioned various components. Therefore, structural equivalents made by using the description and drawings of the present invention or by directly or indirectly applying to other related arts are also encompassed within the scope of the present invention.
