Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, in particular to an adapter, a cartridge, a cartridge group and an image forming device. BACKGROUND

[0002] The image forming device is a device for forming an image on a medium through an imaging processing technology. The image forming device comprises a body and a cartridge assembly composed of a plurality of cartridges, wherein the body is provided with an imaging assembly, the cartridges are usually detachably installed in the body and can provide carbon powder for printing to the imaging assembly. The body of the image forming device is provided with a first conductive contact, and the cartridge is provided with a second conductive contact. When the cartridge is installed in the body of the image forming device, the first conductive contact and the second conductive contact are in contact and electrically connected. When the carbon powder in the cartridge is used up, a new cartridge needs to be replaced.

[0003] However, when the user replaces the cartridge, the movement of the cartridge during the installation and removal process will cause a certain amount of carbon powder to scatter, and the scattered carbon powder will adhere to the first conductive contact on the body side of the image forming device, causing the first conductive terminal on the body side of the image forming device to be contaminated. After replacing the cartridge, the second conductive contact on the cartridge and the first conductive contact on the body side will not be in good contact, affecting the normal operation of the image forming device.

[0004] In addition to the above, when the user does not install the cartridge in the image forming device, foreign matter enters the image forming device and scratches the first conductive contact on the body side of the image forming device, causing the first conductive contact to be damaged. When the cartridge is installed, the second conductive contact on the cartridge and the first conductive contact on the body side will not be in good contact, so that the image forming device cannot recognize the cartridge, and the image forming device further appears an error prompt, causing inconvenience to the user.

[0075] As described in the background, the image forming device in the related art has a problem that the powder cartridge and the conductive contact on the body side of the image forming device are not in contact after the powder cartridge is replaced. The inventors have found that the cause of this problem is that when the toner in the powder cartridge is used up, a new powder cartridge needs to be replaced. However, during the replacement of the powder cartridge, the first conductive contact on the body side of the image forming device is adhered with toner, and the first conductive contact is contaminated or damaged, resulting in that the replaced powder cartridge and the first conductive contact on the body side are not in contact, which affects the normal work of the image forming device.

[0076] To solve the above technical problems, the embodiments of the present application provide an adapter, a cartridge, a cartridge set and an image forming device, wherein the adapter is capable of being mounted on the powder cartridge, and the adapter cooperates with the protection mechanism of the body of the image forming device through the forcing piece thereof. When the powder cartridge with the adapter is inserted into the body and mounted in place, the protection piece is in the second position and accommodated in the accommodation cavity of the powder cartridge, and the protection of the first conductive contact is released, so that the first conductive contact is exposed in the accommodation cavity, so that the first conductive contact and the second conductive contact are in contact and electrically connected. Conversely, when the powder cartridge with the adapter is not inserted into the body, the protection piece is in the first position and protects the first conductive contact.

[0077] In this way, the protection mechanism is cooperated during the replacement of the powder cartridge, so that the protection piece protects the first conductive contact, prevents the first conductive contact from being adhered with toner, or the first conductive contact from being contaminated or damaged, so that the second conductive contact provided on the replaced powder cartridge is in stable contact with the first conductive contact, thereby ensuring the normal work of the image forming device.

[0078] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more apparent and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0079] Embodiment one

[0080] For the convenience of describing the embodiments of the present application, first, the coordinate system in the drawing is described, wherein the X-axis is defined as the first direction, which can be the length direction of the image forming apparatus body 200, and can also be regarded as the left and right direction; the Y-axis direction is defined as the second direction, which can be the width direction of the image forming apparatus body 200, and can also be regarded as the front and back direction; and the Z-axis direction is defined as the third direction, which can be the height direction of the image forming apparatus body 200, and can also be regarded as the up and down direction.

[0081] As shown in Figure 1 and Figure 2 , the image forming apparatus provided by the embodiments of the present application comprises a body 200 and a cartridge group and an imaging assembly 240 installed in the body 200, wherein the body 200 comprises an installation cavity 201, and the front end of the installation cavity 201 has a socket in the second direction, so as to facilitate the installation of the cartridge group and the imaging assembly 240 into the installation cavity 201.

[0082] Specifically, the image forming apparatus body 200 is in a rectangular shape, which is provided with an installation cavity 201, and the installation cavity is in a rectangular shape or other irregular shape; the front end of the installation cavity 201 has a socket for the cartridge group in the second direction, and a front cover 250 that can be opened and closed is arranged at the edge of the socket, and the front cover 250 can seal the socket when it is in a closed state, so as to close the installation cavity 201.

[0083] In the embodiments of the present application, the cartridge group can comprise at least one cartridge, and the cartridge group can be installed into the installation cavity 201, that is, the cartridge group can be detachably installed into the body 200, and further, the image forming apparatus can install at least one cartridge, which can be a toner cartridge 100, and the toner cartridge 100 contains toner for printing.

[0084] In the third direction, the cartridge group can be arranged above the imaging assembly 240, and the cartridge group comprises four toner cartridges 100 arranged in sequence in the first direction, and each cartridge can contain toner of different colors, which is not limited in the embodiments. When the toner cartridge 100 is installed into the installation cavity 201 and positioned, the toner cartridge 100 can provide toner to the imaging assembly 240, and the second conductive contact of the toner cartridge 100 is in contact with and electrically connected to the first conductive contact of the image forming apparatus body 200.

[0085] However, in the related art, when the toner of the toner cartridge is consumed, the toner cartridge needs to be replaced, and in the replacement process, the first conductive contact is exposed, and the surface of the first conductive contact is easy to adhere to toner and be contaminated or damaged, which causes the second conductive contact on the new toner cartridge to be abnormally electrically connected to the first conductive contact after the toner cartridge is replaced, thereby affecting the normal work of the image forming apparatus.

[0086] Therefore, as shown in Figure 3 and Figure 4 , the image forming apparatus provided by the embodiments of the present application comprises a body 200 and a cartridge group and an imaging assembly 240 installed in the body 200, wherein the body 200 comprises an installation cavity 201, and the front end of the installation cavity 201 has a socket in the second direction, so as to facilitate the installation of the cartridge group and the imaging assembly 240 into the installation cavity 201.As shown, this application embodiment provides an adapter that can be installed on the toner cartridge 100. For example, the adapter can be detachably installed on the housing 20 of the toner cartridge 100, or the adapter and the housing 20 can be integrally formed; this application embodiment does not limit this.

[0087] Specifically, along the second direction (the direction in which the powder cartridge 100 is inserted into the mounting cavity 201 of the body 200), the housing 20 includes a first end and a second end opposite to each other, wherein during the insertion of the powder cartridge 100, the first end of the housing 20 is closer to the body 200, that is, the first end of the housing 20 enters the mounting cavity 201 before its second end.

[0088] The adapter includes a pusher 10 disposed at the first end of the housing 20. The pusher 10 is configured to apply an insertion force from the toner cartridge 100 in a second direction to the protection mechanism of the body 200 during the insertion of the toner cartridge 100, thereby causing the protection mechanism to change position in a third direction.

[0089] For example, when the protection mechanism is in the first position, it can protect the first conductive contact. When the pusher 10 acts on the protection mechanism and puts the protection mechanism in the second position, the protection mechanism can release the protection of the first conductive contact, so that the first conductive contact is exposed and makes contact with and electrically connected to the second conductive contact 42.

[0090] like Figures 5 to 7 As shown, the image forming apparatus body 200 provided in this application embodiment includes the above-mentioned protection mechanism 220 and the first conductive contact 230. A rear frame 210 is provided in the mounting cavity 201. The protection mechanism 220 is disposed on the rear frame 210 and is configured to cooperate with the push member 10 to receive the force from the push member 10. Under the action of this force, the protection mechanism 220 changes its position in the third direction.

[0091] The protective mechanism 220 includes a protective element 223, such as a protective cover. The first conductive contact 230 is configured as an elastic contact structure. A portion of the first conductive contact 230 is electrically connected to the body 200, and a portion of the first conductive contact 230 is exposed in the mounting cavity 201. When the toner cartridge 100 is inserted into the mounting cavity 201 and installed in place, the first conductive contact 230 can contact and be electrically connected to the second conductive contact 42. In this application, "installed in place" means that the toner cartridge 100 is installed in the image forming apparatus body 200 and can perform image forming operations, such as normal printing and normal toner supply.

[0092] Correspondingly, the toner cartridge 100 not only includes the shell 20 and the second conductive contact 42, but also includes a receiving portion 101 configured to form a space for receiving the protection member 223 when the toner cartridge 100 is inserted into the body 200 along the second direction, so that the protection member 223 can be inserted into the space to avoid interference between the protection member 223 and the shell 20, and ensure that the first conductive contact 230 and the second conductive contact 42 are opposite to each other in the third direction and can be electrically connected after the toner cartridge 100 is installed in place.

[0093] As shown in FIGS. 1 and 2, in an embodiment, the protection member 223 is arranged below the first conductive contact 230 in the third direction and protects the first conductive contact 230. Figure 7 and Figure 8 As shown in FIGS. 1 and 2, in an embodiment, the protection member 223 is arranged below the first conductive contact 230 in the third direction and protects the first conductive contact 230.

[0094] As shown in FIGS. 1 and 2, in an embodiment, the protection member 223 is arranged below the first conductive contact 230 in the third direction and protects the first conductive contact 230. Figures 9 to 12 As shown in FIGS. 1 and 2, in an embodiment, the protection member 223 is arranged below the first conductive contact 230 in the third direction and protects the first conductive contact 230.

[0095] Compared with the related art, the adapter provided in the embodiments of the present application can cooperate with the protection mechanism 220 during replacement of the toner cartridge 100 to protect the first conductive contact 230 from being adhered with toner or being contaminated or damaged, so that the second conductive contact 42 of the replaced toner cartridge 100 can stably contact the first conductive contact 230, thereby ensuring normal operation of the image forming apparatus.

[0096] On the basis of the above-described embodiments, the adapter provided in the embodiments of the present application is detachably installed on the shell 20 of the toner cartridge 100, and the adapter includes a mounting mechanism configured to mount the urging member 10 to the shell 20.

[0097] Specifically, the mounting mechanism comprises a mounting portion for mounting the pushing piece 10 on the shell 20 of the powder box 100. For example, the mounting mechanism can be a clamping assembly, and the pushing piece 10 is mounted on the shell 20 through the clamping assembly. The mounting portion can be configured as a buckle and a clamping groove matched with the buckle, wherein the buckle is arranged on the shell 20, and the clamping groove is arranged on the pushing piece 10, and the pushing piece 10 is clamped to the buckle of the shell 20 through the clamping groove, so as to realize the detachable mounting of the pushing piece 10 on the shell 20.

[0098] With reference to the above Figure 4 , it should be noted that in the embodiment of the present application, the shell 20 is provided with one pushing piece 10 on each side along the second direction, and the two pushing pieces 10 can be symmetrically arranged on the shell 20. In this way, when the powder box 100 is inserted into the mounting cavity 201 of the main body 200, the protection mechanism 220 can be uniformly stressed, so as to ensure that it can be moved from the first position to the second position.

[0099] On the basis of the above embodiment, the pushing piece 10 comprises a first guide inclined surface 11, and the first guide inclined surface 11 is configured to be inclined upward along the second direction (the insertion direction of the powder box 100); during the insertion of the powder box 100 into the mounting cavity 201, the first guide inclined surface 11 is in contact with the protection mechanism 220.

[0100] As shown in Figure 6 , in an embodiment, the protection mechanism 220 comprises a guide rail 225 and a first elastic member 224, wherein the length direction of the guide rail 225 is consistent with the second direction, and the guide rail 225 slides up and down along the third direction relative to the rear frame 210, and the protection piece 223 can move together with the guide rail 225. The first elastic member 224 is consistent with the third direction in the extension direction, and one end of the first elastic member 224 is connected with the guide rail 225 and provides the guide rail 225 with elastic force or restoring force along the third direction.

[0101] Along the second direction, one end of the guide rail 225 away from the rear frame 210 is provided with a second guide inclined surface 2251 matched with the first guide inclined surface 11, and the second guide inclined surface 2251 extends downward along the second direction; as the powder box 100 is inserted into the mounting cavity 201, the first guide inclined surface 11 is in contact with the second guide inclined surface 2251, so that the insertion force from the powder box 100 along the second direction is converted into a component force along the third direction under the action of the first guide inclined surface 11, so that the guide rail 225 moves downward along the third direction, and thus the protection piece 223 can be moved from the first position to the second position.

[0102] Further, to ensure that the first guide slope 11 contacts the protection mechanism 220 first during the insertion of the powder box 100, the urging piece 10 is arranged at the first end of the housing 20 in the embodiment, and the first guide slope 11 protrudes from the end surface of the first end of the housing 20 along the second direction, that is, along the insertion direction of the powder box 100. Compared with the end surface of the first end of the powder box 100, the first guide slope 11 is closer to one side of the body 200, so as to ensure that the first guide slope 11 contacts the second guide slope 2251 first compared with the end surface of the first end. In this way, the fit reliability of the first guide slope 11 and the second guide slope 2251 can be ensured.

[0103] In another embodiment, the urging piece 10 not only includes the first guide slope 11, but also includes the first horizontal bearing surface 12, and the first horizontal bearing surface 12 is connected with the first guide slope 11. Along the second direction, the first horizontal bearing surface 12 is located on the side of the first guide slope 11 away from the body 200, that is, during the insertion of the powder box 100 into the mounting cavity 201, the first guide slope 11 contacts the second guide slope 2251 first compared with the first horizontal bearing surface 12.

[0104] Correspondingly, the guide rail 225 also includes the second horizontal bearing surface 2252, and the second horizontal bearing surface 2252 is connected with the second guide slope 2251. The second horizontal bearing surface 2252 is located on the side of the second guide slope 2251 away from the housing 20, and the second horizontal bearing surface 2252 is configured to be fitted with the first horizontal bearing surface 12.

[0105] When the powder box 100 is inserted into the containing cavity of the body 200 and the first guide slope 11 and the second guide slope 2251 are fitted, the first guide slope 11 can apply a pressure to the first elastic piece 224, so as to make the guide rail 225 move downward along the third direction, and then make the protection piece 223 move from the first position to the second position.

[0106] When the first horizontal bearing surface 12 is fitted with the second horizontal bearing surface 2252 as the powder box 100 continues to be inserted along the second direction, the protection mechanism 220 and the powder box 100 can be limited in the third direction, so as to make the protection piece 223 be in the second position. When the powder box 100 is installed in place, the protection piece 223 is contained in the containing portion 101 of the housing 20, and the first conductive contact 230 is in contact with and electrically connected with the second conductive contact 42.

[0107] As Figure 13As shown, in order to reduce the friction when the first guide slope 11 is in contact with the second guide slope 2251, the urging member 10 provided by the embodiment of the present application further comprises a first roller 13, which is rotatably arranged at the first guide slope 11, and at least part of the outer circumferential surface of the first roller 13 protrudes from the first guide slope 11, so as to ensure that when the first guide slope 11 is in contact with the second guide slope 2251, the second guide slope 2251 can be in contact with the outer circumferential surface of the first roller 13, thereby reducing the friction when the first guide slope 11 and the second guide slope 2251 are in contact.

[0108] As shown, Figure 14 In order to reduce the friction when the first guide slope 11 is in contact with the second guide slope 2251, the second guide slope 2251 can be provided with a second roller 226, which is rotatably arranged at the second guide slope 2251, and at least part of the outer circumferential surface of the second roller 226 protrudes from the second guide slope 2251, so as to ensure that when the first guide slope 11 is in contact with the second guide slope 2251, the first guide slope 11 can be in contact with the outer circumferential surface of the second roller 226, thereby reducing the friction when the first guide slope 11 and the second guide slope 2251 are in contact.

[0109] Alternatively, in order to reduce the friction when the first guide slope 11 is in contact with the second guide slope 2251, the first guide slope 11 is provided with a first roller 13, and at the same time, the second guide slope 2251 is provided with a second roller 226, which is not limited by the embodiment of the present application.

[0110] As shown, Figures 15 to 17 In another embodiment, when the urging member 10 provided by the embodiment of the present application is in contact with the protection mechanism 220, the protection member 223 moves upward along the third direction and exposes the first conductive contact 230, so as to achieve the purpose of removing the protection of the first conductive contact 230, and further, the second conductive contact 42 of the powder cartridge 100 can be in contact with and electrically connected to the first conductive contact 230.

[0111] Specifically, along the second direction (the insertion direction of the powder cartridge 100), the first guide slope 11 of the urging member 10 extends obliquely downward. Correspondingly, the protection mechanism 220 comprises a second guide slope 2251 which cooperates with the first guide slope 11.

[0112] For example, the protection mechanism 220 also comprises a guide rail 225 and a protection member 223, the protection member 223 is linked with the guide rail 225 and can move together with the guide rail 225, the first end of the guide rail 225 slides up and down relative to the rear frame 210, the second end of the guide rail 225 is used to contact the urging member 10, the second guide slope 2251 is located at the second end of the guide rail 225, and the second guide slope 2251 extends obliquely upward along the second direction, and the second guide slope 2251 can be in contact with the first guide slope 11.

[0113] It should be noted that the urging member 10 in this embodiment further comprises a first horizontal bearing surface 12 which is in communication with the first guide slope 11, and correspondingly, the guide rail 225 further comprises a second horizontal bearing surface 2252 which is in communication with the second guide slope 2251.

[0114] As shown in Figure 18 and Figure 19 when the powder cartridge 100 is inserted into the accommodating cavity of the body 200, and the first guide slope 11 and the second guide slope 2251 are in contact, the first guide slope 11 can apply pressure to the first elastic member 224, so as to move the guide rail 225 in the third direction upward, and then move the protection member 223 from the first position to the second position, at this time, the protection member 223 moves above the first conductive contact 230 and exposes the first conductive contact 230, and the protection of the first conductive contact 230 is removed.

[0115] When the first horizontal bearing surface 12 and the second horizontal bearing surface 2252 are in contact as the powder cartridge 100 continues to be inserted in the second direction, the protection mechanism 220 and the powder cartridge 100 can be limited in the third direction at this time, so that the protection member 223 is in the second position, and when the powder cartridge 100 is installed in place, the first conductive contact 230 is in contact with and electrically connected to the second conductive contact 42.

[0116] Embodiment Two

[0117] Referring to Figure 3 and Figure 4 the powder cartridge 100 provided by the embodiment of the present application comprises a shell 20, the shell 20 comprises a cavity and a powder outlet which is in communication with the cavity, the cavity is used for accommodating carbon powder, and the carbon powder can be provided to the imaging assembly 240 for printing by the powder outlet.

[0118] The shell 20 is in a whole long cylindrical shape, and comprises opposite first and second ends along the second direction, wherein the shell 20 comprises a mounting area, the mounting area is located at the first end of the shell 20, and the mounting area is provided with a mounting mechanism, and the mounting mechanism is used for mounting the adapter in the above embodiments.

[0119] For example, the adapter comprises the urging member 10, and the mounting mechanism can be a clamping assembly, and the urging member 10 is mounted to the shell 20 through the clamping assembly. The clamping assembly comprises a buckle and a clamping groove which is matched with the buckle, wherein the buckle is arranged on the shell 20, the clamping groove is arranged on the urging member 10, and the urging member 10 is clamped to the buckle of the shell 20 through the clamping groove, so as to realize detachable mounting of the urging member 10 on the shell 20.

[0120] On the basis of the above-mentioned embodiments, the powder box 100 provided by the embodiments of the present application can be detachably arranged on the image forming device body 200. For example, the body 200 is provided with a mounting cavity 201, and the powder box 100 can be inserted into the mounting cavity 201. The shell 20 is provided with the accommodating portion 101, the second conductive contact 42, and the above-mentioned pushing piece 10. For the scheme that the accommodating portion 101 and the pushing piece 10 cooperate with the protection mechanism 220 of the body 200, details are not described herein again, and can be referred to Embodiment 1.

[0121] The powder box 100 provided by the embodiments of the present application not only includes the adapter arranged on the shell 20, but also includes the storage device 40 and the bracket 30 for mounting the storage device 40. Specifically, the storage device 40 can be a chip, which is used to store information such as toner of the powder box 100, and the storage device 40 is used to be electrically connected with the first conductive contact 230 of the body 200 to establish communication between the powder box 100 and the image forming device.

[0122] The storage device 40 includes a substrate 41 and a plurality of communication terminals arranged on the substrate 41, and the communication terminals are configured as the second conductive contact 42. The bracket 30 is used to carry the storage device 40. For example, the bracket 30 is arranged on the end face of the first end of the shell 20, and the bracket 30 is located at an upper position of the end face of the first end along the third direction. The substrate 41 is mounted on the bracket 30, so as to realize mounting of the storage device 40 on the shell 20.

[0123] Further, the bracket 30, the shell 20, and the substrate 41 surround the accommodating portion 101, and the accommodating portion 101 is provided with an opening in the second direction. The opening cooperates with the protection piece 223, so that the protection piece 223 can be accommodated into the accommodating portion 101 through the opening in the process of inserting the powder box 100 into the mounting cavity 201, to avoid interference between the protection piece 223 and the shell 20, and also to make the first conductive contact 230 opposite to the second conductive contact 42.

[0124] It should be noted that the bracket 30 itself is provided with the accommodating portion 101. For example, the bracket 30 is configured as a mounting box, and the box body has an accommodating space. The substrate 41 can be arranged on the top of the mounting box or in the box body, and the embodiments of the present application do not limit this. One side wall of the box body is provided with an opening, and the opening cooperates with the protection piece 223. In the process of inserting the powder box 100 into the mounting cavity 201, the protection piece 223 can be accommodated into the accommodating portion 101 through the opening.

[0125] Reference is made to Figure 7 and Figure 12In one embodiment, the substrate 41 is arranged on the top of the support 30, and the second conductive contact 42 is arranged on the side of the substrate 41 away from the support 30, i.e. the second conductive contact 42 is arranged on the side away from the accommodating portion 101. Accordingly, the second conductive contact 42 can be opposite to the first conductive contact 230, when the cartridge 100 is inserted into the body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodating portion 101, the second conductive contact 42 is below the first conductive contact 230, and the two are in contact and electrically connected.

[0126] As shown in FIG. 1, in one embodiment, the substrate 41 is arranged on the top of the support 30, and the second conductive contact 42 is arranged on the side of the substrate 41 away from the support 30, i.e. the second conductive contact 42 is arranged on the side away from the accommodating portion 101. Accordingly, the second conductive contact 42 can be opposite to the first conductive contact 230, when the cartridge 100 is inserted into the body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodating portion 101, the second conductive contact 42 is below the first conductive contact 230, and the two are in contact and electrically connected. Figure 20

[0127] For example, the first conductive contact 230 is arranged in the groove of the protection member 223. Alternatively, the top surface of the protection member 223 is provided with a conductive sheet 270 electrically connected with the first conductive contact 230, when the protection member 223 is accommodated in the accommodating portion 101, the conductive sheet 270 is in contact with the second conductive contact 42, and the conductive sheet 270 can be an elastic conductive sheet 270.

[0128] When the cartridge 100 is inserted into the image forming apparatus body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodating portion 101, the groove is opposite to the first conductive contact 230, the second conductive contact 42 is below the first conductive contact 230, and the two are in contact and electrically connected.

[0129] As shown in FIG. 1, in one embodiment, the substrate 41 is arranged on the top of the support 30, and the second conductive contact 42 is arranged on the side of the substrate 41 away from the support 30, i.e. the second conductive contact 42 is arranged on the side away from the accommodating portion 101. Accordingly, the second conductive contact 42 can be opposite to the first conductive contact 230, when the cartridge 100 is inserted into the body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodating portion 101, the second conductive contact 42 is below the first conductive contact 230, and the two are in contact and electrically connected. Figure 21 Figure 22 To protect the second conductive contact 42 during the insertion of the cartridge 100, the cartridge 100 further comprises a first protective cover 43, which is slidably arranged on the support 30 in the second direction, and the first protective cover 43 covers the second conductive contact 42 from above, in which case the substrate 41 is arranged on the top of the support 30, and the second conductive contact 42 is arranged on the side of the substrate 41 away from the support 30.

[0130] The first protective cover 43 is configured to be pushed by the protection member 223 to slide and expose the second conductive contact 42, when the cartridge is inserted into the body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodating portion 101.

[0131] ​​For example, the protection member 223 is provided with a first push member 260 matched with the first protective cover 43, the first push member 260 is located on the sliding path of the first protective cover 43, when the powder cartridge 100 is inserted into the mounting cavity 201, the first push member 260 can abut against the first protective cover 43 and push the first protective cover 43 to move towards the direction opposite to the insertion direction, thereby exposing the second conductive contact 42, so that the second conductive contact 42 is located below the first conductive contact 230 and the two are in contact and electrically connected.

[0132] On the basis of the above-mentioned embodiments, in order to further protect the second conductive contact 42 when the powder cartridge 100 is pulled out of the body 200, a second elastic member 44 is arranged between the first protective cover 43 and the support 30, the extension direction of the second elastic member 44 is consistent with the insertion direction of the powder cartridge 100, and the second elastic member 44 is located on the side of the first protective cover 43 away from the first push member 260. The second elastic member 44 is configured to provide elastic force to the first protective cover 43.

[0133] When the powder cartridge 100 is inserted into the mounting cavity 201, the first push member 260 contacts the first protective cover 43, the first push member 260 is fixed with the body 200, and under the action of the insertion force of the powder cartridge 100, the elastic force of the second elastic member 44 is overcome, at this time the second elastic member 44 is started to be compressed, and the first protective cover 43 slides. When the powder cartridge 100 is inserted into the body 200 and installed in place, the second elastic member 44 is in a compressed state, and the first protective cover 43 slides to the side of the base plate 41 and exposes the second conductive contact 42, so that the second conductive contact 42 is located below the first conductive contact 230 and the two are in contact and electrically connected.

[0134] Conversely, when the powder cartridge 100 is separated from the mounting cavity 201, that is, the protection member 223 is separated from the containing portion 101, the first push member 260 gradually separates from the first protective cover 43, and the second elastic member 44 resets, so that the first protective cover 43 moves above the base plate 41 and covers the second conductive contact 42 to protect the second conductive contact 42.

[0135] As shown in FIG. 1, Figure 23 In other embodiments, the powder cartridge 100 provided by the present application sets the chip at other positions of the shell 20, for example, along the third direction, sets the chip on the bottom wall of the shell 20, in this way, the second conductive contact 42 of the powder cartridge 100 can be prevented from being scratched or contaminated.

[0136] Specifically, the powder cartridge 100 further comprises a conversion component 70, the conversion component 70 is arranged on the top of the shell 20, and the conversion component 70 is signal-connected with the second conductive contact 42 through a wire. The conversion component 70 is configured as a plurality of conductive sheets arranged on the top of the shell 20, and the plurality of conductive sheets are respectively arranged corresponding to the plurality of first conductive contacts 230.

[0137] Further, the adapter component 70 is configured to electrically connect the conductive pieces of the adapter component 70 to the plurality of first conductive contacts 230 when the cartridge 100 is inserted into the body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodation portion 101.

[0138] In some embodiments, the chip is movably arranged on the housing 20, the chip is slidably installed on the housing 20 along a third direction, and the chip is hidden in the housing 20. When the second conductive contact 42 needs to be connected to the first conductive contact 230, the chip can be moved upward along the third direction and contact the first conductive contact 230.

[0139] For example, as shown in Figure 24 and Figure 25 , a resilient member A is arranged below the substrate 41 of the chip, and the resilient member A provides an elastic force to the substrate 41. The top surface of the substrate 41 is provided with the second conductive contact 42, and the second conductive contact 42 is lower than the top surface of the housing 20 in the initial state. When the cartridge 100 is inserted into the body 200 and installed in place, and the protection member 223 is in the second position and accommodated in the accommodation portion 101, the chip can be unlocked, and under the action of the resilient member A, the substrate 41 moves upward and is electrically connected to the first conductive contact 230.

[0140] Embodiment Three

[0141] As shown in Figure 26 and Figure 27 , the cartridge 100 provided by the embodiment of the present application is arranged on the safety area of the housing 20, and the pusher 10 is slidably arranged on the housing 20 along the third direction. When the pusher 10 contacts the protection mechanism 220, the pusher 10 can extrude the protection mechanism 220 along the third direction under the action of an external force, so that the protection member 223 moves from the first position to the second position.

[0142] Specifically, the cartridge 100 further comprises a linkage mechanism 60, and the linkage mechanism 60 comprises a linkage 61 and a pivot 62. The pivot 62 is arranged at a middle position of the linkage 61, and the linkage 61 is rotatably connected to the side wall of the housing 20 through the pivot 62. The housing 20 comprises opposite first and second ends. The pusher 10 is slidably arranged on the first end side wall of the housing 20, and the top of the pusher 10 is connected to one end of the linkage 61.

[0143] The second end of the housing 20 is provided with a rotatable handle 50, and the other end of the linkage 61 is connected to the handle 50. When the handle 50 is rotated, the linkage 61 follows the rotation. For example, when the handle 50 is counterclockwise rotated, the linkage 61 can apply a downward pressure to the pusher 10, thereby driving the pusher 10 to move downward.

[0144] When the powder cartridge 100 is inserted into the installation cavity 201 of the body 200, the pushing member 10 contacts the protection mechanism 220 (e.g., the guide rail 225), and the rotating handle 50 is rotated to transmit a force to the pushing member 10, which acts on the guide rail 225 and compresses the first elastic member 224. The protection member 223 moves to the second position in the third direction and is separated from the first conductive contact 230, so that the first conductive contact 230 is exposed, i.e., the protection of the first conductive contact 230 is removed. Then, the second conductive contact 42 moves to the position opposite to the first conductive contact 230, and the two are electrically connected.

[0145] Embodiment Four

[0146] The cartridge set provided in the embodiments of the present application can be detachably installed on the body 200 of the image forming device, and the cartridge set includes a plurality of cartridges.

[0147] Specifically, the cartridge set can be inserted into the installation cavity 201 of the body 200, and the cartridge can be the powder cartridge 100 containing carbon powder for printing. In the third direction, the cartridge set can be arranged above the imaging assembly 240, and the cartridge set includes four powder cartridges 100 arranged in the first direction in sequence. Each cartridge can contain carbon powder of a different color, which is not limited in the embodiments of the present application.

[0148] When the powder cartridge 100 is installed into the installation cavity and positioned, the powder cartridge 100 can provide carbon powder to the imaging assembly 240. Specifically, the imaging assembly 240 includes a photosensitive drum, a cleaning blade, a discharger, a charging assembly, and a developing assembly, wherein the charging assembly can uniformly charge the surface of the photosensitive drum. The exposure assembly exposes and scans the photosensitive drum by laser to make the uniformly charged surface of the photosensitive drum carry an electrostatic latent image. The electrostatic latent image is developed by the developing assembly and carbon powder, and is transferred to an intermediate transfer belt. After the transfer is completed, the cleaning blade removes the carbon powder remaining on the surface of the photosensitive drum, and the discharger removes the electric charge remaining on the photosensitive drum, so that the photosensitive drum is ready for the next imaging.

[0149] Further, to facilitate the differentiation of the above-mentioned powder cartridges 100, the sizes of the pushing members 10 of each powder cartridge 100 can be different, thereby achieving the fool-proofing process. Here, the fool-proofing is to prevent the powder cartridges 100 in the cartridge set from being installed in the wrong positions, such as the black powder cartridge 100 being installed in the position of the yellow powder cartridge 100, or the powder cartridges 100 being installed in reverse in the body 200. For example, in some embodiments, the sizes of the pushing members 10 are different, and the shapes and styles thereof can also be different, which is not limited in the embodiments of the present application.

[0159] On the basis of the above embodiment, the mounting frame 221 in the embodiment of the present application comprises a first door body 2211 and a second door body 2212, the first door body 2211 and the second door body 2212 extend in the third direction, and the first door body 2211 and the second door body 2212 are oppositely and spacedly arranged on the rear frame 210 in the first direction, and the first door body 2211 and the second door body 2212 are located at the insertion opening of the toner cartridge.

[0160] The first door body 2211 and the second door body 2212 are respectively slidably connected with the two sides of the bearing plate 222. The side walls of the first door body 2211 and the second door body 2212 that are close to each other are respectively provided with sliding grooves that extend in the third direction, and the two sides of the bearing plate 222 are respectively slidably installed in the sliding grooves. Further, the two sides of the bearing plate 222 are respectively provided with sliding rails, which cooperate with the sliding grooves, i.e., the bearing plate 222 is slidably installed in the sliding grooves of the mounting frame 221 through the sliding rails.

[0161] It should be noted that the first door body 2211 and the second door body 2212 in the embodiment of the present application are detachably installed on the rear frame 210, and the bottom of the first door body 2211, the bottom of the second door body 2212 and the bearing plate 222 are respectively provided with the first elastic member 224, and the extension direction of the first elastic member 224 is consistent with the third direction, and the first elastic member 224 is used to provide elastic force to the bearing plate 222.

The force receiving arm is arranged on the side of the bearing plate 222 away from the back frame 210. The first end of the force receiving arm is connected with the bearing plate 222, and the second end of the force receiving arm extends in the second direction, and the extending direction is consistent with the insertion direction of the powder cartridge 100.

[0163] Exemplarily, in an embodiment, in order to guide the insertion of the powder cartridge 100 into the main body 200, two guide rails 225 are arranged on the two sides of the bearing plate 222 respectively. The two guide rails 225 are oppositely and spacedly arranged in the first direction, and each guide rail 225 is configured as the above-mentioned force receiving arm.

The second end of the guide rail 225 is provided with a second guide inclined surface 2251 and a second horizontal bearing surface 2252 which are connected with each other. The second guide inclined surface 2251 is located on the side of the second horizontal bearing surface 2252 away from the bearing plate 222 and extends obliquely downward, that is, when the powder cartridge 100 is inserted into the mounting cavity 201, the second guide inclined surface 2251 contacts the pushing piece 10 first.

At this time, the protection piece 223 moves above the first conductive contact 230 and exposes the first conductive contact 230, and the protection of the first conductive contact 230 is removed.

[0167] With the continuous insertion of the powder cartridge 100 in the second direction, when the first horizontal bearing surface 12 is attached with the second horizontal bearing surface 2252, the protection mechanism 220 and the powder cartridge 100 can be limited in the third direction at this time, so as to make the protection piece 223 be in the second position. With the powder cartridge 100 being installed in place, the first conductive contact 230 contacts and is electrically connected with the second conductive contact 42.

[0172] Embodiment six

[0173] The image forming device provided by the embodiments of the application comprises a body 200 and a cartridge, and in the cartridge type shown in the embodiments, a photosensitive drum, a charging roller and a toner storage developing device are integrated to form a cartridge, and the cartridge is configured to be detachable from the body 200 of the image forming device. Further, although the above-mentioned cartridge is described as an example, the application is not limited thereto, for example, a developing cartridge comprising toner and a developing device but not a photosensitive drum can be used. A toner cartridge not comprising a roller can also be used. Alternatively, a photosensitive drum cartridge not comprising a developing device and integrating a photosensitive drum and a charging roller can also be used.

[0174] It should be noted that the working process of the image forming device provided by the embodiments of the application is as follows:

[0175] As shown in Figure 30As shown, the image forming apparatus can be a printer provided with four cartridges 6Y, 6M, 6C and 6K that generate yellow, magenta, cyan and black toner images (referred to as Y, M, C and K toner images). The cartridges use Y, M, C and K toner having different colors from each other as an image forming base, but the four cartridges have the same configuration and are replaceable with new cartridges at each toner replenishment. For example, the cartridge 6Y that generates a Y toner image is described as a representative example of the four cartridges.

[0176] The cartridge 6Y includes a drum-shaped photoconductor 1Y, a drum cleaning device, a discharger (not shown), a charging device and a developing device. The cartridge 6Y is detachably mounted on the body, and these components are disposable. The charging device uniformly charges the surface of the photoconductor that rotates in a clockwise direction by a driving unit (not shown). Exposure scanning is performed by a laser L, and the uniformly charged surface of the photoconductor is caused to carry an electrostatic latent image thereby. The electrostatic latent image is developed by the developing device that uses Y toner for the Y toner image.

[0177] Further, intermediate transfer is performed on an intermediate transfer belt 8. After the intermediate transfer processing, the drum cleaning device removes toner remaining on the surface of the photoconductor. In addition, the discharger removes residual electric charges from the photoconductor after cleaning. The surface of the photoconductor is initialized by discharging, which prepares for the next imaging. Likewise, in the other cartridges 6M, 6C and 6K, M, C and K toner images are similarly formed on the photoconductors 1M, 1C and 1K, and intermediate transfer is performed on the intermediate transfer belt 8.

[0178] An exposure device 7 is provided in the lower portion of each of the cartridges 6Y, 6M, 6C and 6K. The exposure device 7 that serves as a latent image forming unit irradiates each photoconductor in the cartridges 6Y, 6M, 6C and 6K with laser light L emitted based on image information, and exposes each photoconductor with the laser light L.

[0179] With respect to exposure, electrostatic latent images of Y, M, C and K are formed on the photoconductors 1Y, 1M, 1C and 1K. In addition, the exposure device 7 irradiates the photoconductors with laser light (L) emitted from a light source by means of a polygon mirror that rotates by a rotation driving motor, through two or more optical lenses and a mirror. A paper feed unit including a paper cassette 26 in which a paper feed roller 27 and a pair of abutting rollers 28 are provided is provided in the bottom portion of the exposure device 7.

[0180] The paper tray 26 contains a large quantity of copy paper P, and the feed roller 27 contacts the top of the copy paper P. As the feed roller 27 rotates counterclockwise due to the drive unit, the top copy paper P is conveyed to a position between the rollers of the opposing roller pair 28. Although the opposing roller pair 28 is driven to rotate and clamp the copy paper P, the rotational drive immediately stops. The copy paper P is then conveyed by the opposing roller pair 28 to the secondary transfer clamping area at an appropriate time. In the above-described paper feeding unit, the combination of the feed roller 27 and the opposing roller pair 28 (timing roller pair) constitutes the conveying unit. This conveying unit conveys the copy paper P from the paper tray 26 to the secondary transfer clamping area.

[0181] An intermediate transfer unit 15, which performs intermediate image transfer using an annular intermediate transfer belt 8 (intermediate transfer medium), is disposed above each toner cartridge 6Y, 6M, 6C, and 6K. This intermediate transfer unit 15 is equipped with four primary transfer bias rollers 9Y, 9M, 9C, and 9K, a cleaning device 14, and the intermediate transfer belt 8. Furthermore, the intermediate transfer unit 15 includes a secondary transfer support roller 16, a cleaning support roller 17, a tension roller, etc. As the intermediate transfer belt 8 rotates counterclockwise, annular transfer is performed driven by the rotation of at least one of these three rollers. The primary transfer bias rollers 9Y, 9M, 9C, and 9K place the intermediate transfer belt 8, which performs the annular transfer, between the photoconductors 1Y, 1M, 1C, and 1K in this manner, and respectively form primary transfer pinch zones.

[0182] In this transfer process, the toner presses the transfer bias with opposite polarity (e.g., positive) against the back side (inner surface of the ring) of the intermediate transfer belt 8. All rollers except for the primary transfer bias rollers 9Y, 9M, 9C, and 9K are electrically grounded.

[0183] As the circular transfer continues, the intermediate transfer belt 8 undergoes a process of passing through the Y, M, C, and K transfer clamping zones one by one. The Y, M, C, and K toner images of the photoconductors 1Y, 1M, 1C, and 1K are superimposed and transferred in one stage. Therefore, a toner image of four superimposed colors (referred to as a 4-color toner image) is formed on the intermediate transfer belt 8.

[0184] In the secondary transfer clamping zone, it is inserted between the intermediate transfer belt 8 and the secondary transfer roller 19, wherein the copy paper P undergoes a surface transfer in the forward direction, and the aforementioned opposing roller pair 28 is conveyed in the opposite direction.

[0185] As the copy paper P, fed from the secondary transfer clamping area, passes between the rollers of the fixing unit 20, heat and pressure are used to fix the four-tone toner image transferred to the surface. Subsequently, the copy paper P is conveyed through the discharge roller pair 29 and discharged outside the printer. A stacking section 30 is provided on the upper surface of the main part of the printer. The copy papers P discharged from the discharge roller pair 29 to the outside of the printer are stacked one by one on the stacking section 30.
