Abstract
Description
Technical Field
[0001] The present application relates to the field of technical image forming, and in particular to an image forming device. Background Art
[0002] An image forming apparatus is an apparatus that forms an image on a printing medium according to an input signal, and a printer, a copier, a fax machine, and a multifunction printer such as an integrated printer, a copier, and a fax machine can be applied to the image forming apparatus.
[0003] Taking a color printer as an example, LSU (laser generator) and CTD-SENSOR (color density correction sensor) are important optical components of the printer. The LSU (laser generator) irradiates light onto the photosensitive drum through a lens, converts the light signal into an electrical signal, and forms an electrostatic latent image on the photosensitive drum; while the CTD-SENSOR (color density correction sensor) emits light onto the color block, and then receives the reflected light to judge the color density, thereby ensuring the image quality. Such optical components are very sensitive to light. The optical components are covered with glass or transparent plastic covers to protect the internal optical components from being contaminated by toner or paper powder. However, after long-term printing, the surface of the LSU (laser generator) or CTD-SENSOR (color density correction sensor) may be contaminated by toner or paper powder, affecting the emission or reception of light, thereby affecting the image quality. Therefore, existing image forming devices have various measures to clean the LSU (laser generator) and CTD-SENSOR (color density correction sensor) to ensure the image quality.
[0004] For example, when the image forming device is not working, the user adopts various measures to clean the LSU (laser generator) or CTD-SENSOR (color density correction sensor), but it is necessary to disassemble part of the image forming device for cleaning, which is very inconvenient for the user. Alternatively, a cleaning drive device is configured inside the image forming device to drive a cleaning brush to clean the optical surface, but this method not only increases the cost, but also requires cleaning when the device is not printing. In addition, the contact cleaning method such as the cleaning brush used in the prior art is not strong enough to remove impurities from the corners of the optical surface. Summary of the invention

[0095] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0096] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[0098] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0099] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.
[0100] like Figure 1 As shown, the present embodiment provides an image forming device 100, which is a device for forming an image on an electric printing medium according to an input signal. Multifunctional printers such as printers, copiers, fax machines, and integrated printers, copiers, and fax machines can be applied to the image forming device 100. The image forming device 100 includes a device body 10, an optical module, an airflow driving module, and an airflow conducting module 20. The optical module is mounted on the device body 10, and an optical component 30 is arranged on the optical module. The optical component 30 has an optical surface 31. The airflow driving module is mounted on the device body 10 to generate an airflow. The airflow conducting module 20 is mounted on the device body 10, and the airflow conducting module 20 receives the airflow generated by the airflow driving module and conducts the airflow through the optical surface 31.
[0101] In this embodiment, the optical surface 31 of the optical component 30 is cleaned by airflow, and the dust such as carbon powder or paper powder falling on the optical surface 31 is cleaned, which can effectively remove the dust at the corners of the optical surface 31, and avoid the dust blocking the optical surface 31 of the optical component 30, thereby affecting the emission or reception of light, and ensuring the image quality. In addition, in this embodiment, the optical surface 31 of the optical component 30 is cleaned by airflow, which can be performed when the image forming device 100 is printing or not printing, further ensuring the quality and stability of the image.
[0102] In this embodiment, the optical component 30 may be a color concentration correction sensor 32 , which is used to perform color correction on the image forming device 100 and is fixed on both sides of the transfer belt on the sheet metal bracket of the device body 10 .
[0103] like Figures 2 to 5 As shown, in some embodiments, the airflow source may be the airflow generated by the device body 10 itself, and the optical surface 31 of the color density correction sensor 32 is cleaned by using the airflow.
[0104] like Figure 2 As shown, the airflow drive module includes a drive assembly 11, a crank slider mechanism 21 and a piston column 221. The drive assembly 11 is connected to the crank slider mechanism 21, and the crank slider mechanism 21 is connected to the piston column 221. The drive assembly 11 can be a waste toner bin drive assembly of the device body 10 itself. The drive assembly 11 includes a waste toner bin drive head 111, an idler wheel 112 and a waste toner bin drive gear 113 that are meshed and driven in sequence. Figure 2 , Figure 4 and Fig. 9 As shown, the air flow conduction module 20 includes a piston seat 222, a slideway 222a is provided in the piston seat 222, a portion of the piston column 221 is located in the slideway 222a, and the piston seat 222 is provided with a vent 222b, which corresponds to the optical surface 31. The waste toner bin driving gear 113 can drive the crank slider mechanism 21 to drive the piston column 221 to reciprocate along the slideway 222a, so that the air flow can be sucked into the slideway 222a along the vent 222b, and pushed to the optical surface 31 along the vent 222b.
[0105] In this embodiment, the driving assembly 11 of the device body 10 is used to drive the conveying roller in the waste toner bin to move, and at the same time, it can provide power for cleaning the optical surface 31 of the color concentration correction sensor 32, so as to generate a cleaning airflow. The specific driving process of generating the airflow is as follows: the waste toner bin drive head 111 drives the idler wheel 112 to rotate, the idler wheel 112 drives the waste toner bin drive gear 113 to rotate, and the waste toner bin drive gear 113 drives the crank slider mechanism 21 to drive the piston column 221 to reciprocate along the slide 222a. When the piston column 221 reciprocates in the slide 222a, an airflow can be generated to clean the optical surface 31 of the color concentration correction sensor 32 through the vent 222b. Specifically, as Fig.10 As shown, the arrow direction X is the movement direction of the piston column 221 and the flow direction of the air flow. When the crank slider mechanism 21 drives the piston column 221 to move in the direction away from the vent 222b, a negative pressure is formed in the cavity of the partial slide 222a between the piston column 221 and the vent 222b, and the air flow in the external environment is sucked into the cavity of the partial slide 222a through the vent 222b. Because the vent 222b is arranged opposite to the optical surface 31 of the color concentration correction sensor 32, during the process of the slide 222a sucking in the air flow, the air flow can bring the dust on the optical surface 31 of the color concentration correction sensor 32 into the slide 222a, so that the surface of the color concentration correction sensor 32 can be cleaned once. Fig.11 As shown, the shear direction Y is the movement direction of the piston column and the flow direction of the airflow. When the crank slider mechanism 21 drives the piston column 221 to move toward the direction close to the vent hole 222b, the piston column 221 can discharge the airflow in the slideway 222a through the vent hole 222b, so that the airflow passes through the optical surface 31 of the color density correction sensor 32, and the optical surface 31 of the color density correction sensor 32 is cleaned again.
[0106] This embodiment directly utilizes the device of the device body 10 itself to form an airflow driving module capable of driving airflow generation, without the need for an additional driving motor, thus saving costs and without occupying the internal space of the device body 10, which is conducive to the miniaturization of the image forming device 100.
[0107] It should be noted that because the air flow diffuses outward when being discharged along the vent hole 222b, the dust carried by the air flow will not completely return to the optical surface 31 of the color concentration correction sensor 32. The optical surface 31 of the color concentration correction sensor 32 can be cleaned by the reciprocating motion of the piston column 221.
[0108] In addition, in this embodiment, the driving assembly 11 can cooperate with the crank rocker, reciprocating screw, worm gear and other components to drive the piston column 221 to reciprocate.
[0109] like Fig. 9and Fig.12 As shown, in order to ensure that the partial cavity of the slideway 222a between the piston column 221 and the vent 222b can form a relatively sealed space, a sealing portion 221a is provided at one end of the piston column 221 close to the vent 222b. During the movement of the piston column 221 along the slideway 222a, the sealing portion 221a remains in contact with the inner wall of the slideway 222a, so that when the piston column 221 moves to the position farthest from the vent 222b, a negative pressure can be formed in the slideway 222a, thereby allowing the air flow to be sucked into the slideway 222a.
[0110] like Figure 6 As shown, in order to realize that the slider crank mechanism 21 can drive the piston column 221 to reciprocate along the slideway 222a, in some embodiments, the slider crank mechanism 21 includes a driving member 211 and a connecting rod 212. The driving member 211 can be a gear structure. The driving member 211 is meshed with the waste powder bin driving gear 113. The mating end of the driving member 211 is provided with a protrusion 211a. The connecting rod 212 is provided with a driving portion 212a, a connecting portion 212b and an output portion 212c. The connecting portion 212b is located between the driving portion 212a and the output portion 212c. The driving portion 212a abuts against the mating end of the driving member 211, and the output portion 212c is connected to the piston column 221. When the waste toner bin driving gear 113 drives the driving member 211 to rotate, the protrusion 211a can be rotated to abut against the driving portion 212a to push the driving portion 212a to swing around the connecting portion 212b in a direction away from the driving member 211, and the driving portion 212a drives the output portion 212c to pull the piston column 221.
[0111] Specifically, if Figure 6 As shown, the side end of the driving member 211 is a mating end that is mated with the connecting rod 212. The mating end is provided with one, two or more protrusions 211a. There are recesses 211b between adjacent protrusions 211a. The movement stroke of the connecting rod 212 along the protrusions 211a and along the recesses 211b is the same. As the driving member 211 rotates, when the protrusion 211a rotates and abuts against the driving portion 212a, the protrusion 211a can push the driving portion 212a to swing around the connecting portion 212b in a direction away from the driving member 211, so that the driving portion 212a drives the output portion 212c to swing around the connecting portion 212b in a direction away from the piston seat 222, so as to pull part of the piston column 221 out of the slide 222a, so that negative pressure is formed in the slide 222a. Fig.11As shown, when the recessed portion 211b rotates to correspond to the driving portion 212a, the driving portion 212a can be pushed to swing in the direction close to the driving member 211 until it fits with the mating end of the driving member 211, so that the protrusion 211a can push the driving portion 212a to swing again. At the same time, the driving portion 212a drives the output portion 212c to move around the connecting portion 212b toward the direction close to the piston seat 222, so as to push the piston column 221 into the slideway 222a, and push the airflow in the slideway 222a along the vent 222b toward the optical surface 31 of the color concentration correction sensor 32. The frequency of cleaning can be controlled by adjusting the number of protrusions 211a set on the driving member 211 and other parameters.
[0112] Alternatively, the driving member 211 may also be a non-gear structure, for example, the driving member 211 is provided with a shaft portion, which is connected to the shaft where the waste toner bin driving gear 113 is located and rotates synchronously to realize the rotation of the driving connecting rod 212 .
[0113] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, in order to achieve that the protrusion 211a can be pushed to fit with the mating end of the driving member 211, in some embodiments, the crank slider mechanism 21 further includes a swing bracket 214, the swing bracket 214 is mounted on the device body 10, and the connecting rod 212 is mounted on the swing bracket 214. The swing bracket 214 is provided with a rotating shaft 214a, and the connecting portion 212b is provided with an axial hole 212b1. The connecting portion 212b is rotatably connected with the rotating shaft 214a through the axial hole 212b1, so that the connecting rod 212 is installed on the swing bracket 214 and can rotate relative to the rotating shaft 214a. The crank slider mechanism 21 further includes an elastic member 213, the elastic member 213 is mounted on the axial hole 212b1, and the two ends of the elastic member 213 extend out of the axial hole 212b1 and respectively abut against the connecting rod 212 and the swing bracket 214. The elastic member 213 can push the driving portion 212 a to swing around the connecting portion 212 b toward the driving member 211 under the action of its own elastic force, and the driving portion 212 a drives the output portion 212 c to push the piston column 221 .
[0114] In this embodiment, when the protrusion 211a pushes the driving part 212a to swing away from the driving member 211, pressure is applied to the elastic member 213, so that the elastic member 213 is squeezed and twisted by the swing bracket 214 and the connecting rod 212, so that the elastic member 213 stores elastic potential energy. With the rotation of the driving member 211, when the recessed part 211b rotates to be opposite to the driving part 212a, the elastic member 213 can release its elastic potential energy, and under the action of its own elastic force, push the driving part 212a to swing around the connecting part 212b in the direction close to the driving member 211, so that the driving part 212a fits with the mating end of the driving member 211, ensuring that the driving member 211 can push the connecting rod 212 to swing again. At the same time, the driving part 212a drives the output part 212c to swing around the connecting part 212b in the direction close to the piston seat 222, so as to push the piston column 221 into the slideway 222a.
[0115] The elastic member 213 may be configured as a torsion spring, or the elastic member 213 may be configured as a tension spring, a spring sheet or a compression spring. The tension spring, spring sheet or compression spring may be configured at one end of the connecting rod 212 to achieve the same effect.
[0116] like Figure 6 As shown, in some embodiments, the output portion 212c is provided with a clamping hole 212c1, and the piston column 221 is provided with a clamping portion 221b, and the clamping portion 221b is clamped and matched with the clamping hole 212c1 to realize the connection between the connecting rod 212 and the piston column 221. By sleeve-connecting the clamping hole 212c1 and the clamping portion 221b, the disassembly and assembly of the connecting rod 212 and the piston column 221 is facilitated.
[0117] like Figure 4 , Figure 7 , Fig.10 and Fig.11 As shown, in some embodiments, when the image forming device 100 is a color printer, the optical component 30 can be set to one, two, or more, and the piston rod 221 and the piston seat 222 are set corresponding to the number of the optical components 30. When two or more optical components 30 are provided, the airflow driving module further includes a connecting plate 223, and the connecting plate 223 can connect adjacent piston rods 221, so that a crank slider mechanism 21 can drive multiple piston rods 221 to reciprocate along the corresponding piston seat 222, thereby cleaning the optical surfaces 31 of multiple optical components 30.
[0118] Specifically, the connecting plate 223 and the piston column 221 can be an integrally formed structure. The connecting plate 223 is connected to both sides of the piston column 221 along a direction perpendicular to the movement of the piston column 221, and the connecting plate 223 can extend along one piston column 221 to pass through the piston seat 222 and connect to another adjacent piston column 221.
[0119] In this embodiment, the image forming device 100 can also use airflow to clean the optical surfaces of optical components when not printing. This can be achieved by adding a cleaning module to the control of the image forming device, so that the driving component is idle to achieve the cleaning function.
[0120] like Fig.13 and Fig.14 As shown, in some embodiments, the airflow source may also be the airflow generated by the fan 12 of the device body 10 itself, and the airflow is used to clean the color density correction sensor 32 and the optical surface 31 of the laser generator 33. The laser generator 33 irradiates light onto the photosensitive drum through a lens, converts the light signal into an electrical signal, and forms an electrostatic latent image on the photosensitive drum. Fig.13 and Fig.15 As shown, the airflow driving module can be a fan 12, and the airflow conduction module 20 includes a panel 23, which is arranged between the fan 12 and the optical component 30 and encloses an air duct 231 that conducts airflow to the optical surface 31. The direction of the arrow in the air duct 231 is the flow direction of the airflow.
[0121] In this embodiment, the fan 12 of the device body 10 is used to generate airflow, so that the airflow can dissipate heat from the device body 10 and can also be used to clean the optical surface 31 of the optical component 30. In addition, through the combination of the fan 12 and the enclosure 23, one fan 12 can remove dust from the surfaces of multiple optical components 30 at the same time, and this cleaning process can be performed regardless of whether the image forming device 100 is printing or not, without affecting the normal printing of the image forming device 100.
[0122] The enclosure 23 can be made of a plastic plate, and a plurality of air outlets can be provided on the enclosure 23 corresponding to each optical component 30 so that the airflow can be concentrated to flow to the optical surface 31 of each optical component, thereby reducing the dispersion of the airflow and ensuring that the airflow flows into the color concentration correction sensor 32 and the laser generator 33.
[0123] Furthermore, if Fig.15 and Fig.16 As shown, the airflow conduction module 20 also includes a dust storage plate 24, which is arranged on both sides of the optical surface 31, and the dust storage plate 24 does not block the optical surface 31. A plurality of dust storage grooves 241 are provided on the side of the dust storage plate 24 opposite to the optical surface 31. The dust storage grooves 241 are arranged at an acute angle to the flow direction of the airflow, and the grooves of the dust storage grooves 241 are inclined toward the flow direction of the airflow, so that the airflow can form vortices in the dust storage grooves 241.
[0124] In this embodiment, the end of the dust storage plate 24 close to the optical surface 31 is serrated to form a plurality of dust storage grooves 241, and the dust storage grooves 241 are grooves that form an acute angle with the advancing direction of the airflow. After part of the airflow enters the dust storage grooves 241, when the airflow advances along the side of the dust storage grooves 241, the part close to the surface is subject to resistance during the advance due to friction caused by the viscosity of the fluid, and therefore advances more slowly than the part far from the surface, thereby rotating to form a small vortex and advance, bringing the dust on the optical surface 31 into the dust storage grooves 241.
[0125] Specifically, Fig.16 As shown, an adsorbent 242 is placed in the dust storage tank 241 to adsorb dust carried by the airflow into the dust storage tank 241. Dust particles flow into the dust storage tank 241 with the vortex and are adsorbed by the adsorbent 242 to prevent dust from flying everywhere, causing pollution in the device body 10 and polluting the external environment. The adsorbent 242 can be activated carbon.
[0126] like Fig.16 As shown, the dust storage plate 24 is also provided with an air guide portion 243, and the air guide portion 243 is opposite to the air outlet of the air duct 231. That is to say, a notch is provided at one end of the dust storage plate 24 close to the enclosure 23, and the notch forms the air guide portion 243. The air guide portion 243 enlarges the air inlet of the dust storage plate 24 on both sides of the optical surface 31, so that the air outlet of the enclosure 23 can be set in the air guide portion 243, thereby guiding the airflow and allowing more airflow to flow to the optical surface 31 of the optical component 30.
[0127] More specifically, the fan 12 may be of axial flow type or centrifugal type, and a data board may be used to control the fan 12 to rotate at a preset air volume and speed.
[0128] In this embodiment, the image forming device 100 can use airflow to clean the optical surfaces of optical components when not printing. This can be achieved by adding a cleaning module to the control of the image forming device so that the fan rotates when the image forming device is not printing to achieve the cleaning function.
[0129] In some embodiments, the air flow conduction modules in the above embodiments may be disposed in the same device body.
[0130] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
