Description

Technical Field

[0001] The invention relates to the technical field of printing, in particular to a combined toner cartridge with circulated replaceable powder boxes. Background Art

[0002] The toner cartridge is the core component of a laser printer. During the printing process, an electrostatic latent image is formed on its surface through laser scanning, which is the basis for printing images. The electrostatic latent image attracts carbon powder particles and converts the latent image into a visible toner image. The toner image is then transferred to the printing paper and fixed on the paper by a fuser to form the final printed image.

[0003] The container for storing carbon powder in the toner cartridge is a toner cartridge. Carbon powder is a colorant used to form an image during the printing process. The toner cartridge is usually designed to be replaceable so that it can be easily replaced when the carbon powder is exhausted.

[0004] However, there are also some toner cartridges that cannot be replaced. This design is usually called an "integrated toner cartridge" or a "closed toner cartridge". In order to save costs, users will add toner by themselves. During the process of adding toner by themselves, toner is dispersed in the air and combined with the air, which is easily inhaled by the human body, affecting human health. In the patent with announcement number CN 114200799 B, it is proposed that when adding toner to a toner cartridge, the powder cartridge needs to be disassembled and then a new powder cartridge needs to be installed to avoid directly dumping the toner, thereby reducing the possibility of toner particles flying. However, it is difficult to have a replaceable powder cartridge in an integrated toner cartridge, so it is still necessary to dump the toner by yourself so that a powder cartridge can be reused to minimize costs. Based on this, it is proposed to add a structure to the integrated toner cartridge so that the integrated toner cartridge can also be added with toner, and the toner cartridge does not need to be disassembled to avoid loosening or leakage of the toner cartridge. Summary of the invention

[0005] The object of the present invention is to provide a combined toner cartridge with circulated replaceable powder boxes to solve the problems raised in the above background technology.

[0007] The toner box is provided with an ejection mechanism for ejecting the toner bin, which is used to connect the toner bin and the toner box, and the ejection mechanism includes a mesh layer for filtering the toner, so as to prevent agglomerated toner from entering the toner box.

[0008] Furthermore, a long strip-shaped powder inlet is provided at the lower end of the installation cavity of the toner cartridge, and a powder outlet is provided at the lower end of the toner bin. The powder outlet is embedded in the powder inlet and is used to discharge the toner in the toner bin into the toner cartridge. The inner wall of the lower end of the toner bin is inclined to concentrate the toner at the powder outlet.

[0009] Furthermore, installation slots are provided on the inner walls on both sides of the installation cavity of the toner cartridge, and a detachable support plate is clamped in the installation slots, and the toner bins are provided with two symmetrical and fitting groups, and external support springs are fixed to the outer sides of the two groups of toner bins, and support circles are fixed to the outer sides of the external support springs, and limiting rings are fixed on the inner walls on both sides of the installation cavity, and the support circles are abutted against the limiting rings for supporting the two groups of toner bins, and the lower ends of the two groups of toner bins are fitted with the inner walls of the installation cavity, and the upper ends thereof are pressed against the support plate, so as to limit the two groups of toner bins and enable them to shake back and forth, and the two groups of toner bins that are shaking always keep the powder inlet blocked.

[0010] Furthermore, an inner support shaft is provided inside the toner cartridge, the inner support shaft is fixed on the inner wall of the toner cartridge, and the ejection mechanism is slidably disposed on the inner support shaft;

[0011] The ejection mechanism also includes a sleeve and an ejection shaft. The sleeve is sleeved on the outside of the inner support shaft. A protruding strip extending along its axis is integrally formed on the outer wall of the inner support shaft. A matching channel that matches the protruding strip is opened on the inner wall of the sleeve. The ejection shaft is fixed to the upper end of the sleeve. A closing cover for sealing is provided on the inner side of the powder outlet. The upper end of the ejection shaft is used to eject the closing cover upward to allow the toner to enter the toner box.

[0012] Furthermore, the mesh layer is fixed on the upper end of the ejection shaft, a frame plate is sleeved on the outside of the ejection shaft, the upper end of the frame plate is fixed to the edge of the mesh layer, so that the mesh layer is arranged in a conical shape, the upper end of the frame plate is abutted against the lower end edge of the powder outlet, and the ejection shaft extends upward out of the powder inlet.

[0013] Furthermore, support sleeves are fixed to the four corners of the powder outlet, a support rod is inserted into the support sleeve, the upper end of the support rod is fixed to the closing cover, and a spring for stretching the support rod inward is provided in the support sleeve.

[0014] Furthermore, a frame-shaped ring layer is fixed on the inner wall of the lower end of the toner bin, the axis of the frame-shaped ring layer coincides with the axis of the powder outlet, and the inner wall of the frame-shaped ring layer fits with the edge of the closing cover.

[0018] 2. When installing the toner bin, the closed cover and the ejection shaft must be against each other to achieve the opening function. When installing the toner bin, the powder outlet is connected to the toner box to prevent the toner from being exposed to moisture for a long time, and to reduce the toner dispersion in the air, reducing the harm to personnel. When adding toner, the toner bin is inverted, the closed cover is opened, and the opening is relatively large, which is convenient for adding toner and improves convenience.

[0019] 3. There is toner inside the toner cartridge, and the toner compartment can be replaced to ensure that the toner will not be interrupted during printing, which can relatively improve the printing quality and maximize the use of resources.

[0020] 4. The external support springs on the outside of the two toner bins can make the two toner bins fit together and make them easy to shake. The toner moves along the inner wall slope at the lower end of the toner bin and moves out from the powder outlet to the greatest extent. The toner inside the toner bin is damp and forms lumps. The lumps of toner can be filtered out through the mesh layer to ensure the quality of the toner. When the toner bin shakes, the ejection mechanism can shake with the toner bin, and the ejection shaft moves in the powder outlet. The mesh of the mesh layer changes, making it easy to filter the toner and avoid jamming. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] See also Figure 1-Figure 9 The present invention provides a technical solution: a combined toner cartridge with a recyclable toner cartridge, comprising an integrated toner cartridge 1, wherein a non-detachable toner cartridge 2 is fixed in the integrated toner cartridge 1, such as Figure 1 As shown, the integrated toner cartridge 1 has other structures not described, and the structures described are prior art and will not be described here. Figure 2 As shown, a mounting cavity 21 is provided on the outer side of the toner cartridge 2, and a detachable toner bin 5 is installed in the mounting cavity 21. The toner bin 5 is located in the mounting cavity 21 and shakes back and forth, so that the toner in the toner bin 5 moves into the toner cartridge 2. It should be noted that the toner cartridge 2 and the toner bin 5 can be separated, wherein the toner cartridge 2 is a structure for mainly holding toner, and the toner bin 5 is a structure for adding toner and secondarily storing toner. The two structures cooperate with each other, and the toner bin 5 can continuously add toner to the toner cartridge 2, so that the toner cartridge 2 always has a relative amount of toner. In addition, the toner cartridge 2 also needs to be disassembled to ensure that the parts of the toner cartridge 2 will not become loose, or the toner cartridge 2 will not leak, thereby affecting the printing quality;

[0034] like Figure 3As shown, the toner cartridge 2 is provided with an ejection mechanism 4 for ejecting the toner bin 5, which is used to connect the toner bin 5 and the toner cartridge 2, so that the toner bin 5 remains connected with the toner cartridge 2 only after installation. Normally, the toner bin 5 is in a relatively closed state to prevent the internal toner from getting damp. In addition, if multiple toner bins 5 are provided, they can be quickly replaced, saving time while preventing the printing device from stopping printing due to lack of toner as much as possible. The ejection mechanism 4 includes a mesh layer 45 for filtering the toner, which is used to prevent agglomerated toner from entering the toner cartridge 2. The mesh layer 45 filters the put in toner, so that the quality of the toner can be maintained as much as possible.

[0035] like Figure 3 and Figure 7 As shown, a long strip-shaped powder inlet 22 is provided at the lower end of the installation cavity 21 of the toner cartridge 2, and a powder outlet 53 is provided at the lower end of the toner bin 5. The powder outlet 53 is embedded in the powder inlet 22, and is used to discharge the toner in the toner bin 5 into the toner cartridge 2. It should be noted that the powder outlet 53 is in a fitted state with the powder inlet 22, and the toner bin 5 is also in a fitted state against the installation cavity 21, so as to prevent the toner from moving outward and maintain a relatively sealed state. The inner wall at the lower end of the toner bin 5 is inclined, so as to concentrate the toner at the powder outlet 53, so that the toner in the toner bin 5 can be concentrated and the toner can be poured into the toner cartridge 2 as much as possible.

[0036] like Figure 2 and Figure 5 As shown, mounting notches 24 are provided on the inner walls of both sides of the mounting cavity 21 of the toner cartridge 2, and a detachable support plate 25 is clamped in the mounting notches 24. The toner bins 5 are provided with two symmetrical and fitted groups, and the outer sides of the two groups of toner bins 5 are fixed with external support springs 51, and the outer sides of the external support springs 51 are fixed with support circles 52. Limiting rings 23 are fixed on the inner walls of both sides of the mounting cavity 21, and the support circles 52 are set in the limiting rings 23 to support the two groups of toner bins 5. The lower ends of the two groups of toner bins 5 fit the inner walls of the mounting cavity 21, and the upper ends thereof are pressed against the support plates 25, so that the toner bins 5 are The toner bin 5 can only slide horizontally due to the limitation, while it can also maintain a relatively sealed state to prevent external gas from entering the toner bin 5 and the toner box 2, so that the internal toner can be kept dry. In addition, the toner bin 5 can be prevented from being taken out due to the action of the support plate 25. The two groups of toner bins 5 are limited and can be shaken back and forth. The two groups of toner bins 5 in the shaking process always keep the powder inlet 22 blocked. The long strip of powder inlet 22 is blocked by the toner bin 5. Even when the toner bin 5 is shaking, the powder inlet 22 is kept in a closed state to prevent it from opening due to shaking.

[0037] like Figure 4As shown, the interior of the toner cartridge 2 is further provided with an inner support shaft 3, the inner support shaft 3 is fixed on the inner wall of the toner cartridge 2, and the ejection mechanism 4 is slidably arranged on the inner support shaft 3, so that the ejection mechanism 4 can slide along the inner support shaft 3, and even when the toner bin 5 moves, the closing cover 54 can be kept lifted outward, so that the toner bin 5 and the toner cartridge 2 are always kept in a connected state;

[0038] The ejection mechanism 4 also includes a sleeve 41 and an ejection shaft 43. The sleeve 41 is sleeved on the outside of the inner support shaft 3. The outer wall of the inner support shaft 3 is integrally formed with a protruding strip 31 extending along its axis. The inner wall of the sleeve 41 is provided with a matching channel 42 that matches the protruding strip 31. The protruding strip 31 and the matching channel 42 cooperate to ensure that the sleeve 41 remains in a sliding state while avoiding rotation, so that the ejection shaft 43 always remains in a vertical upward state. The ejection shaft 43 is fixed to the upper end of the sleeve 41. A closing cover 54 for closing is provided on the inner side of the powder outlet 53. The upper end of the ejection shaft 43 is used to eject the closing cover 54 upward to allow the toner to enter the toner cartridge 2. The closing cover 54 can be opened only when the toner bin 5 cooperates with the toner cartridge 2. In the absence of cooperation, the toner bin 5 is in a closed state.

[0039] like Figure 4 and Figure 7 As shown, the mesh layer 45 is fixed to the upper end of the ejection shaft 43, and a frame plate 44 is sleeved on the outer side of the ejection shaft 43. The upper end of the frame plate 44 is fixed to the edge of the mesh layer 45, so that the mesh layer 45 is set in a conical shape. The upper end of the frame plate 44 is against the lower edge of the powder outlet 53. The ejection shaft 43 extends upward out of the powder inlet 22. When the ejection shaft 43 pushes the closing cover 54 upward, the frame plate 44 is clamped on the lower edge of the powder outlet 53, so that the mesh layer 45 is set in a conical shape. The conical mesh layer 45 can contact with the toner on a larger surface, so that the toner can pass through the mesh layer 45 as much as possible. Figure 8 As shown, the stuck block toner will move along the conical mesh layer 45 to the frame plate 44 to avoid clogging the mesh layer 45.

[0040] like Fig. 9 As shown, support sleeves 542 are fixed to the four corners of the powder outlet 53, a support rod 541 is inserted into the support sleeve 542, the upper end of the support rod 541 is fixed to the closing cover 54, and a spring for stretching the support rod 541 inward is provided in the support sleeve 542. It should be noted that when the closing cover 54 is not subjected to an upward force, the closing cover 54 is supported on the powder outlet 53 under the action of the spring contraction, thereby achieving a closing effect.

[0041] A frame-shaped ring layer 543 is also fixed on the inner wall of the lower end of the toner bin 5, the axis of the frame-shaped ring layer 543 coincides with the axis of the powder outlet 53, and the inner wall of the frame-shaped ring layer 543 fits closely with the edge of the closing cover 54 to prevent the toner from moving outward.

[0042] The mesh layer 45 is elastically arranged, and is in a horizontal state when not subjected to force, so that the mesh layer 45 can be deformed for easy operation.

[0043] The working principle of the present invention is as follows: when the integrated toner cartridge 1 is disassembled to add toner, the support plate 25 is moved out horizontally so that the toner bin 5 can be taken out upward, and the taken out toner bin 5 can be added with toner separately through the powder outlet 53. The toner bin 5 after adding toner is clamped in the installation cavity 21, and the powder outlet 53 is clamped in the powder inlet 22. The upper end of the toner bin 5 is also against the installed support plate 25 to limit the toner bin 5 so that the toner bin 5 can only move back and forth. Under the action of the ejection shaft 43, the closing cover 54 is ejected upward so that the powder outlet 53 is in an open state, so that toner can enter the toner box 2 from the toner bin 5, so as to add toner to the toner box 2 and avoid disassembly of the toner box 2, thereby ensuring that the toner box 2 is in a sealed state, avoiding loosening or reduced sealing of the toner box 2, and also avoiding damage to the toner cartridge.

[0044] When the toner bin 5 is removed or not installed, the powder outlet 53 of the toner bin 5 is in a closed state under the action of the closing cover 54, which can prevent the toner in the toner bin 5 from moving outward. When the toner bin 5 is installed, the closing cover 54 is against the ejection shaft 43 to achieve the opening function, that is, when the toner bin 5 is installed, the powder outlet 53 is connected with the toner box 2 to prevent the toner from being exposed to the outside for a long time and getting damp, and also reduce the toner dispersion in the air, reducing the harm to personnel. In addition, when adding toner to the toner bin 5, the toner bin 5 is inverted, and the closing cover 54 is pushed inward to open the closing cover 54. The opened mouth is relatively large, which is convenient for adding toner and improves convenience.

[0045] In addition, when there is toner inside the toner cartridge 2 but there is not much toner, the toner chamber 5 can also be replaced to ensure that the toner will not be interrupted during printing, thereby relatively improving the printing quality. Compared with a toner cartridge that is replaced after the toner is used up, or a toner cartridge that is replaced before the toner is used up, the integrated toner cartridge 1 can make maximum use of the toner, ensure that printing will not be interrupted, and no waste will be generated during the replacement of the toner cartridge 2, thereby maximizing the use of resources.

[0046] It should be noted that after the toner bin 5 is installed, the closed cover 54 is supported by the mesh layer 45 so that the closed cover 54 is pushed open. However, the toner moving outward from the powder outlet 53 requires a certain amount of thrust or shaking force. The external support springs 51 on the outer sides of the two groups of toner bins 5 can not only fit the two groups of toner bins 5 together, but also facilitate shaking. During the shaking process, the internal toner will move along the inclined surface of the inner wall at the lower end of the toner bin 5 and move out from the powder outlet 53 to the greatest extent. In addition, since the toner bin 5 is connected to the outside world through the powder outlet 53, the external air can enter the inside during the connection process, which can easily make the internal toner damp, so that the local toner may form a block. The toner in the powder outlet 53 needs to pass through the mesh layer 45 to move downward, which can filter out the block toner and prevent it from entering the toner box 2, thereby ensuring the quality of the toner.

[0047] In addition, when the toner bin 5 shakes, the ejection shaft 43 of the ejection mechanism 4 is squeezed on both sides of the powder outlet 53, and the ejection mechanism 4 can shake with the toner bin 5, and the ejection shaft 43 is moved in the powder outlet 53, so that the mesh layer 45 is deformed, and the mesh holes of the mesh layer 45 can also be changed, so that the toner can be easily filtered to avoid jamming.
