Description

Technical Field

[0001] The invention relates to the technical field of printing, in particular to a toner cartridge which is easy to clean. Background Art

[0002] The toner cartridge is mainly composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. It is an electronic imaging device that converts electronic signals into actual images through the charging and exposure process. In a laser printer, the toner cartridge is responsible for providing toner to the printer and forming an electrostatic latent image on its surface. The toner on the magnetic roller of the developer chamber is then adsorbed to the exposed area through high-voltage static electricity, and the printing process is finally completed.

[0003] The waste toner bin is an important part of the toner cartridge, used to collect waste toner generated during the printing process. As the number of prints increases, waste toner in the waste toner bin will gradually accumulate. If not cleaned in time, waste toner may overflow, pollute the printer, and even affect the print quality and normal operation of the printer. In the process of cleaning the waste toner bin, it is necessary to disassemble the toner cartridge, and then use a vacuum cleaner or soft cloth to gently suck out or wipe the waste toner in the waste toner bin. At the same time, avoid excessive force during the cleaning process to avoid damaging the structure of the toner cartridge or the waste toner bin.

[0004] When cleaning waste powder, it is inevitable to come into contact with it. Waste powder contains many fine carbon powder particles, which are easily dispersed in the air during the cleaning process and easily enter the respiratory system of personnel, affecting their health. In addition, even if personnel have certain protection, waste powder is in the air and difficult to remove, which will still cause certain harm to personnel and the environment. Therefore, when cleaning, it is necessary to avoid contact between waste powder and outside air. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 9 The present invention provides a technical solution: a toner cartridge that is easy to clean, such as Figure 1 As shown, the toner cartridge body 1 includes a waste toner bin 2 in the middle and end covers 3 connected to the waste toner bin 2 on both sides. It should be noted that the toner cartridge body 1 also includes other components that are not listed here, such as Figure 2 As shown, the waste powder bin 2 is provided with a waste powder processing part 4 for adsorbing waste powder, and the waste powder processing part 4 includes a matching cover 1 41, a matching cover 2 42 and a connecting shaft part 43;

[0035] like Figure 2 and Figure 4 As shown, the matching cover 1 41 and the matching cover 2 42 are snap-fitted together, and the opening and closing of the matching cover 1 41 and the matching cover 2 42 are used to absorb the waste powder in the waste powder bin 2. The connecting shaft 43 is connected to the matching cover 1 41, and is used to drive the opening and closing of the matching cover 1 41 and the matching cover 2 42 and to transmit the absorbed waste powder. The waste powder is absorbed out under the opening and closing action of the waste powder processing part 4, and the waste powder can be directly collected without opening the waste powder bin 2.

[0036] like Figure 3As shown, the shapes of the matching cover 1 41 and the matching cover 2 42 are the same as the shape of the inner cavity of the waste powder bin 2. Brush bristles 5 are fixed on the outer wall of the matching cover 1 41. The brush bristles 5 are used to brush off the waste powder on the inner wall of the waste powder bin 2. It should be noted that the waste powder in the waste powder bin 2 may become compacted due to long-term accumulation. It is difficult to suck out the waste powder inside by adsorption alone. Therefore, it is necessary to break up the waste powder inside and keep it in a relatively loose state. The use of the brush bristles 5 can avoid damaging the waste powder bin 2 and break up the waste powder.

[0037] like Figure 5 As shown, the connecting shaft portion 43 includes a support shaft 434 fixed to the inner wall of the matching cover 1 41, the support shaft 434 horizontally penetrates the matching cover 2 42, and the reciprocating motion of the support shaft 434 is used to control the opening and closing of the matching cover 1 41 and the matching cover 2 42;

[0038] An inner support spring 411 is fixed between the matching cover 1 41 and the matching cover 2 42 for support. The inner support spring 411 is used to control the separation and matching of the matching cover 1 41 and the matching cover 2 42. It should be noted that the matching cover 1 41 is fixed to the support shaft 434, while the matching cover 2 42 can slide, so that the matching cover 2 42 can open and close with the matching cover 1 41 under the action of inertia as it moves, thereby realizing a change in the space between the two.

[0039] like Figure 5 As shown, a bayonet 436 is provided on the outer side of the matching cover 42, and a clamping edge 435 is integrally provided on the outer wall of the support shaft 434. The clamping edge 435 cooperates with the bayonet 436 to keep the matching cover 42 in a state parallel to the matching cover 41. It should be noted that the clamping edge 435 cooperates with the bayonet 436 to form a close fit to avoid gas leakage as much as possible. Even if local gas leakage occurs, the chamber between the matching cover 41 and the matching cover 42 can still produce positive and negative pressure changes, driving the gas to enter from the air inlet 421 and exit from the air outlet 437.

[0040] like Figure 6 and Figure 7As shown, an opening is provided at the lower end of the matching cover 41, and two outer cover plates 412 symmetrically arranged are fixed to the lower end surface of the matching cover 41, and an inner cover plate 422 is fixed to the lower end of the matching cover 42. The inner cover plate 422 is embedded in the opening at the lower end of the matching cover 41, and the two sides of the lower end of the inner cover plate 422 are in contact with the opening at the lower end of the matching cover 41, and the lower end of the inner cover plate 422 is in contact with the two outer cover plates 412 to clamp the inner cover plate 422. An air inlet 421 is fixed through the inner cover plate 422, and a one-way valve is fixed in the air inlet 421 for adsorbing gas from the outside to the inside. It should be noted that the main function of setting the outer cover plate 412 and the inner cover plate 422 is to make the chamber between the matching cover 41 and the matching cover 42 relatively sealed, so that the positive and negative pressure inside can change, so that the one-way valve can work and suck the gas outward.

[0041] An air outlet 437 is provided on the outer wall of the support shaft 434, and a one-way valve is also fixed in the air outlet 437. The interior of the support shaft 434 is hollow, and the interior of the support shaft 434 is connected to the air outlet 437. The gas moving outward from the air outlet 437 passes through the interior of the support shaft 434 and moves outward along the interior of the support shaft 434.

[0042] like Figure 4 As shown, the outer end of the support shaft 434 is rotatably connected to a blocking cover 431, and the blocking cover 431 is used to cooperate with the end cover 3 on one side to block the waste powder. A connecting pipe mouth 433 is also fixed to the outer side of the blocking cover 431, and the interior of the support shaft 434 is connected to the connecting pipe mouth 433 to discharge the waste powder. It should be noted that the blocking cover 431 is fitted in the recessed layer 32, which can make the interior of the waste powder bin 2 relatively sealed, prevent the waste powder inside from moving out, and also keep the waste powder processing part 4 relatively in a fixed state to avoid affecting printing.

[0043] The inner side of the end cover 3 on one side is integrally formed with a cylinder 31 with a hole, and the inner wall of the cylinder 31 is provided with a thread. The outer side of the end cover 3 is provided with a recessed layer 32, which is connected to the cylinder 31, and the axes of the two coincide. A threaded tube 432 is fixed to the inner side of the stop cover 431, and the threaded tube 432 is inserted into the cylinder 31 and cooperates with the thread in the cylinder 31. The threaded tube 432 is rotated and tightened to achieve that the stop cover 431 and the threaded tube 432 are in a fixed state, which can make the waste powder processing part 4 relatively in a sealed state. At the same time, under the effect of the self-locking of the thread, looseness is avoided and the fixing effect is achieved. The support shaft 434 penetrates The support shaft 434 passes through the cylinder 31, and the outer wall of the support shaft 434 contacts the inner wall of the hole of the cylinder 31. When the support shaft 434 moves, the waste powder inside is relatively prevented from moving out of the hole. The cylinder 31 realizes the supporting function. The blocking cover 431 is embedded in the recessed layer 32. When the waste powder processing part 4 is working, the blocking cover 431 is separated from the recessed layer 32, so that the gas can enter the waste powder bin 2, and relatively make the waste powder bin 2 not sealed, so that the gas can also enter the waste powder processing part 4 to suck out the waste powder. When the blocking cover 431 is embedded in the recessed layer 32, the waste powder bin 2 is in a relatively sealed state, so as to prevent the waste powder inside from moving out.

[0044] The second matching cover 42 is made of metal, and the outer wall of the second matching cover 42 fits with the inner wall of the first matching cover 41. Figure 8 and Fig. 9 As shown, the arrow indicates the direction of movement, so that positive and negative pressure changes can be performed between the matching cover 2 42 and the matching cover 1 41.

[0045] The working principle of the present invention is as follows: when the waste powder bin 2 needs to be cleaned, the toner cartridge body 1 is taken out and the blocking cover 431 is rotated so that the support shaft 434 can be flexibly moved. When the waste powder in the waste powder bin 2 is adsorbed, the support shaft 434 is reciprocated so that the support shaft 434 is located in the waste powder bin 2 and reciprocates. Since the support shaft 434 and the matching cover 1 41 are in a fixed state, the matching cover 1 41 also reciprocates in the waste powder bin 2. In addition, the matching cover 2 42 is connected to the matching cover 1 41 through the internal support spring 411. The matching cover 2 42 also has a certain mass. Therefore, when the matching cover 1 41 reciprocates, the matching cover 1 Cover 2 42 also moves, and under the action of inertia, it opens and closes with the matching cover 1 41, so that the space between the matching cover 1 41 and the matching cover 2 42 changes. Under the action of the air inlet 421 and the air outlet 437, gas enters from the outside into the space between the matching cover 1 41 and the matching cover 2 42, and is discharged from the air outlet 437 to the outside, so that the waste powder in the waste powder bin 2 can be discharged without disassembling the toner cartridge body 1, and it will not be combined with the outside air, and the discharged waste powder can be directly collected to avoid affecting the health of personnel. It is also convenient to collect the waste powder, so that the toner cartridge body 1 can be recycled, and the cleaning process of the waste powder bin 2 is relatively simple.

[0046] In addition, during the movement of the matching cover 41, the bristles 5 on its outer side also move along with it. Since the shape of the matching cover 41 is the same as that of the waste powder bin 2, the bristles 5 contact the inner wall of the waste powder bin 2. The bristles 5 clean the inner wall of the waste powder bin 2, and the waste powder adhered to the waste powder bin 2 falls to the bottom, and the waste powder is collected.

[0047] When installing or removing the toner cartridge body 1, the blocking cover 431 is matched with the recessed layer 32, the threaded tube 432 on one side of the blocking cover 431 is matched with the cylinder 31, and the hole of the cylinder 31 supports the support shaft 434, so that the matching cover 1 41 and the matching cover 2 42 do not contact the waste powder bin 2 under the support, and maintain a relatively suspended state, so that the surrounding bristles 5 are in contact with the waste powder bin 2, so that the waste powder processing part 4 and the toner cartridge body 1 are in an integrated arrangement and can be flexibly operated. In addition, the threaded tube 432 on one side of the blocking cover 431 is matched with the cylinder 31 to achieve a sealing effect to prevent the waste powder on the inner wall from moving outward, and the two one-way valves also prevent the waste powder from moving outward.

[0048] When the waste powder processing part 4 reciprocates, the waste powder is adsorbed. Then, during the adsorption process, the waste powder processing part 4 can move along the waste powder bin 2 to adsorb waste powder at different positions. At the same time, the waste powder can be in a flying state during the brushing of the bristles 5, which is convenient for entering the waste powder processing part 4 with the gas. In particular, the agglomerated waste powder can be loosened under the action of the bristles 5.
