[0043] Embodiment one

[0044] Reference Figure 1As shown, the embodiment of the present application discloses a processing cartridge 100, which is detachably installed in an image forming apparatus 200. The image forming apparatus 200 includes a paper cassette 201, a paper feeding roller 202, a first conveying roller 203, a laser 204, a transfer roller 205, a fixing unit 206, a second conveying roller 207 and a paper discharge cassette 208. The processing cartridge 100 includes a main body 1, which includes a cartridge body 11, and / or an imaging assembly, and / or a developing assembly. The cartridge body 11 is provided with a containing cavity for containing a developer (the developer can be, for example, carbon powder). The imaging assembly at least includes a photosensitive drum 13 and a charging roller 14. The developing assembly at least includes a developing roller 15. The first conveying roller 203 is arranged in a paper feeding path of the image forming apparatus 200. The second conveying roller 207 is arranged in a paper discharging path of the image forming apparatus 200. The paper cassette 201 is used for storing paper sheets 300. The paper feeding roller 202 is used for conveying the paper sheets 300 stored in the paper cassette 201 to the paper feeding path. The first conveying roller 203 is used for conveying the paper sheets 300 to a clamping area of the photosensitive drum 13 and the transfer roller 205. The charging roller 14 is used for charging the surface of the photosensitive drum 13. The laser 204 is used for emitting a laser beam to form an electrostatic latent image on the surface of the photosensitive drum 13. The developing roller 15 is used for conveying the developer contained in the cartridge body 11 to the photosensitive drum to develop an image on the surface of the photosensitive drum 13. When the paper sheets 300 pass through the clamping area of the photosensitive drum 13 and the transfer roller 205, the photosensitive drum 13 transfers the image formed on the surface thereof to the paper sheets under the action of the transfer roller 205 and the like. The fixing unit 206 is used for fixing the image on the paper sheets 300. The fixed paper sheets 300 are conveyed to the paper discharge cassette 208 by the second conveying roller 207. Of course, it can be understood that the above image forming apparatus 200 is one of the more typical structures, but the image forming apparatus 200 also has other types of structures, and the processing cartridge and the detection method in the present application can also be applied.

[0045] During the image forming operation of the image forming apparatus 200, there are various situations, for example, the environmental temperature and humidity are too high or too low; or the circuit elements are damaged or malfunctioned; or the circuit transmission is out of order. The above situations will affect the working stability of the processing cartridge and the printing quality, but the problems cannot be found in time at present, which will affect the printing effect and cause the waste of the printing medium.

[0046] The application provides a processing box 100 for being detachably installed in an image forming device 200, comprising a main body 1 for storing a developing agent and a working element arranged in the main body 1 for detecting or obtaining a first parameter related to the processing box 100; wherein when the first parameter or a second parameter obtained based on the first parameter does not meet an expectation, the image forming device 200 controls the processing box 100 to stop conveying the developing agent. When the processing box 100 is installed in the image forming device 200, the image forming device 200 can obtain the first parameter or the second parameter obtained based on the first parameter related to the processing box 100 based on the working element, and when the first parameter or the second parameter does not meet the expectation, the processing box 100 stops conveying the developing agent, so as to prevent the processing box 100 from affecting the printing effect due to the high or low temperature and humidity in the environment, the damage or failure of the circuit element, the circuit output problem and the like in the process of printing.

[0047] Optionally, the working element is a working environment sensor 2 for detecting the first parameter related to the processing box 100, and the image forming device 200 obtains the first parameter; or the working element is a fixed resistor for enabling the image forming device 200 to obtain the first parameter; or the working element is an adjustable resistor for enabling the image forming device 200 to obtain the first parameter.

[0048] When the working element is the working environment sensor 2, the image forming device 200 can obtain the environmental information such as temperature, humidity and light intensity of the processing box 100 through the working environment sensor 2, and stops conveying the developing agent when the environmental information does not meet the expectation, so as to prevent the developing agent from being affected by the environment and interfering with the printing effect; when the working element is the fixed resistor or the adjustable resistor, the image forming device 200 can obtain the electric signal such as current and voltage of the processing box 100 through the fixed resistor or the adjustable resistor, and stops conveying the developing agent when the electric signal does not meet the expectation, so as to prevent the circuit or the electrical element electrically connected with the image forming device 200 on the processing box 100 from being damaged or failing to cause the information to be unable to be transmitted or the transmission to have an error, thereby affecting the printing effect.

[0049] Optionally, the adjustable resistor is a positive adjustment resistor, and whether the circuit is normally operated can be judged through the positive adjustment resistor; if the first parameter obtained by the image forming device 200 or the second parameter obtained based on the first parameter does not meet the expectation, it indicates that there is a problem in the adjustable resistor or the circuit electrically connected with the image forming device, which may affect the information transmission.

[0050] Optionally, when the working element is a variable resistor, the variable resistor comprises a switching element and at least two branch circuits, the switching element is configured to receive an instruction signal and switch different branch circuits to form a variable resistor with different resistance values for electrically connecting with the image forming device. By switching the switching element and the at least two branch circuits, the different branch circuits are switched on and the variable resistor with different resistance values is formed, and when the power supply is stable, the resistance adjustment of the variable resistor will cause the voltage, current and other electrical characteristic coefficients to change accordingly. If the change of the electrical characteristic coefficients does not meet the expectation, for example, when the resistance value of the variable resistor is controlled to change, the corresponding electrical characteristic coefficients do not change accordingly, or the change cannot correspond to the resistance value, there is a problem with the working element or the circuit electrically connected with the image forming device.

[0051] Optionally, the at least two branch circuits are arranged in parallel, the resistance values of the different branch circuits are different, the switching element comprises at least two controlled switches, one controlled switch is arranged on one branch circuit, based on different instruction signals corresponding to different temperatures, different controlled switches are closed to make one branch circuit conductive, and the rest of the branch circuits are disconnected, and when different branch circuits are switched on, the variable resistor presents different resistance values; or the variable resistor comprises at least two branches, the at least two branches are arranged in parallel, the switching element comprises at least two controlled switches, one controlled switch is arranged on one branch, based on different instruction signals corresponding to different temperatures, different numbers of controlled switches are closed to form branch circuits with different resistance values, and when different controlled switches are opened or closed, the resistance value of the variable resistor also changes accordingly, and at this time, the resistances of the different branch circuits can be the same or different.

[0052] Further, the temperature in the above-mentioned "different instruction signals corresponding to different temperatures" can be provided by a temperature sensor arranged on the frame body of the image forming device 200 or the process cartridge 100, and corresponding different instruction signals are given based on different temperatures.

[0053] In addition, when the working element is a variable resistor, the variable resistor can also be a potentiometer, a variable circuit, etc.

[0054] The following is further illustrated by setting the working element as the working environment sensor 2, and it can be understood that the working element can also be set as a fixed resistor or a variable resistor, or different kinds of working environment sensors 2 cooperate with each other, or the working environment sensor 2 cooperates with the fixed resistor or the variable resistor:

[0055] During the image forming operation in the image forming apparatus 200, heating or friction may cause the processing cartridge 100 to heat up. The developer stored in the processing cartridge 100 is affected by environmental parameters, such as temperature and humidity. If the environmental parameters of the processing cartridge 100 are too high or too low, the developer stored in the processing cartridge 100 may clump together, affecting the delivery of the developer and the printing effect.

[0056] Reference Figure 2 and Figure 3 As shown, the processing cartridge 100 also includes an information processing device 3 and an environment sensor 2. The information processing device 3 is disposed on the main body 1 and is used to communicate with the image forming apparatus 200. Further, the information processing device 3 is used to store relevant parameters of the processing cartridge 100, such as the type of the processing cartridge 100, the number of printed pages, and the remaining amount of developer. The environment sensor 2 is disposed on the outside or inside of the main body 1 and is used to detect or acquire a first parameter related to the processing cartridge 200. The first parameter may include temperature or humidity, or may include electrical characteristic parameters that characterize temperature, humidity, etc., such as resistance, current, or voltage. The device that acquires the first parameter can determine the corresponding value, such as temperature or humidity, based on these electrical characteristic parameters. In this embodiment, the environment sensor 2 is used to detect or acquire the first parameter related to the processing cartridge 200. The environment sensor 2 can directly detect and acquire the aforementioned first parameter, or it can be used in conjunction with other components to detect and acquire the aforementioned first parameter, as long as the environment sensor 2 participates in the detection of the first parameter. The aforementioned first parameter is used to indicate the environment in which the main body 1 is located. When the processing cartridge 100 is installed in the image forming apparatus 200, the contacts on the image forming apparatus 200 can be electrically connected to the information processing device 3 and the operating environment sensor 2, thereby enabling the image forming apparatus 200 to perform authentication or data transmission with the processing cartridge 100. Further explanation is needed: the contacts on the image forming apparatus 200 can directly or indirectly contact the operating environment sensor 2. The information processing device 3 includes a chip, which includes a communication module. When the processing cartridge 100 is installed in a predetermined position within the image forming apparatus 200, the chip communicates with the image forming apparatus 200 through the communication module. It is understood that the information processing device 3 may also include external circuitry in addition to the chip; that is, the information processing device 3 includes the chip and external circuitry electrically connected to the chip.

[0057] It is also understood that the information processing device 3 may have multiple chips, wherein: at least two chips are electrically connected to each other; or at least two chips are not electrically connected to each other and communicate with the image forming device 200 respectively.

[0058] Optionally, the information processing device 3 comprises a first unit and a second unit, the first unit is electrically connected with the second unit, the storage module is arranged in the first unit, the first calculation module or the second calculation module is arranged in the second unit, one of the first unit and the second unit is a chip, and the other of the first unit and the second unit is a chip or an external circuit. That is, the storage module, the first calculation module and the second calculation module can be arranged on the chip or the external circuit.

[0059] Of course, it can be understood that if the working environment sensor 2 is arranged as a fixed resistor or an adjustable resistor, the first parameter is an electrical characteristic parameter, such as a resistance value, a current or a voltage, etc.

[0060] In some embodiments, the information processing device 3 comprises a communication module, the communication module is used for communicating with the image forming device, and the communication module and the working environment sensor 2 are used for being electrically connected with the same or different contacts on the image forming device 200.

[0061] Further, the communication module comprises a data terminal, and the information processing device 3 is electrically connected with the image forming device 200 through the data terminal. For example, the data terminal is in contact with and electrically connected with a stylus, a contact or a spring sheet arranged on the image forming device 200.

[0062] In addition, the communication module can also be a separate circuit module, for example, an external circuit electrically connected with the chip.

[0063] In some embodiments, when the processing cartridge 100 is mounted on the image forming device 200, the communication module and the working environment sensor 2 can be electrically connected with the same contact of the image forming device 200, and at this time, the communication with the information processing device 3 and the acquisition of the first parameter measured by the working environment sensor 2 can be realized through the same contact of the image forming device 200, the number of contacts and the corresponding circuit arrangement on the image forming device 200 can be reduced, the structure is simplified, and the cost is reduced.

[0064] In some embodiments, when the processing cartridge 100 is mounted on the image forming device 200, the communication module and the working environment sensor 2 are respectively electrically connected with different contacts of the image forming device 200. For example, the information processing device 3 has a transmission terminal different from the data terminal, the working environment sensor 2 is electrically connected with one contact of the image forming device 200 through the transmission terminal on the information processing device 3, and the data terminal on the information processing device 3 is electrically connected with another contact of the image forming device 200; or the information processing device 3 is not provided with a transmission terminal for the working environment sensor 2 to be electrically connected, the working environment sensor 2 is not electrically connected with the information processing device 3 but is directly electrically connected with one contact of the image forming device 200, and the data terminal on the information processing device 3 is electrically connected with another contact of the image forming device 200.

[0065] In some embodiments, when the first parameter or the second parameter obtained based on the first parameter does not meet the expectation, the image forming apparatus 200 controls the process cartridge 100 to stop conveying the developer, exemplarily, when the first parameter is the temperature, the working environment sensor 2 detects the temperature of the main body 1 in real time when the process cartridge 100 is installed on the image forming apparatus 200, and the image forming apparatus 200 can obtain the temperature of the main body 1, when the temperature of the main body 1 is too high or too low, the image forming apparatus 200 will stop performing the image forming operation and cool down until the temperature of the main body 1 is reduced to the preset temperature range, and then restart the image forming operation, to prevent the process cartridge 100 from causing the developer to be agglomerated due to the internal temperature being too high or too low during the image forming operation. Of course, the working environment sensor 2 can also be a sensor capable of obtaining other types of first parameters of the process cartridge 100, such as humidity and the like.

[0066] In the present embodiment, the working environment sensor 2 is arranged outside the main body 1, specifically, the cartridge body 11 includes a base body 111 and an upper cover 112, the upper cover 112 and the base body 111 are connected and surround a containing cavity capable of containing the developer, as shown in Figure 4 The main body 1 further includes an end cover 12, the end cover 12 is assembled to the end of the base body 111, and the end cover 12 surrounds the installation cavity 101 with the upper cover 112 and the base body 111, the installation cavity 101 is arranged close to the containing cavity of the cartridge body 11, wherein the installation cavity 101 can be an installation space, an installation slot, an installation hole or an installation notch, etc. Exemplarily, the end cover 12 is provided in an inverted L shape, the lower part of the end cover 12 is connected with the end of the base body 111, and the upper part of the end cover 12 is arranged spaced apart from the base body 111, so that the upper part of the end cover 12, the base body 111 and the upper cover 112 surround the installation cavity 101. The working environment sensor 2 can be inserted into the installation cavity 101 from outside to inside of the installation cavity 101, so that the working environment sensor 2 is at least partially located in the installation cavity 101. The information processing apparatus 3 can be mounted on the end cover 12, or can be mounted on the base body 111 or the upper cover 112. The present embodiment arranges the working environment sensor 2 outside the main body 1, so as to prevent the working environment sensor 2 from being contaminated by the developer, and at the same time, the working environment sensor 2 is arranged close to the cartridge body 11, so as to improve the detection accuracy.

[0067] In the embodiment, the cartridge body 11 comprises two independent parts, i.e. the base 111 and the cover 112. It is understood that in other embodiments, the cartridge body 11 can be integrally formed. The end cover 12 is assembled to the end of the cartridge body 11, so that the end cover 12 and the cartridge body 11 enclose the mounting cavity for mounting the working environment sensor 2. In order to facilitate the mounting of the working environment sensor 2, the cartridge body 11 further comprises a mounting member 113 connected to at least one of the cartridge body 11 and the end cover 12, and the mounting member 113 is provided with a gap. The working environment sensor 2 can be inserted into the gap of the mounting member 113 from outside the mounting cavity 101, so that the working environment sensor 2 is mounted at the gap of the mounting member 113. Exemplarily, the mounting member 113 can be connected to the base 111 or the cover 112.

[0068] In the embodiment, the working environment sensor 2 is detachably electrically connected to the information processing device 3. Exemplarily, the processing cartridge 100 further comprises a socket provided on the cartridge body 11 and electrically connected to the information processing device 3. The working environment sensor 2 comprises a temperature measuring portion, a connecting portion and a plug. The connecting portion is connected to the temperature measuring portion. The temperature measuring portion is mounted at the gap of the mounting member 113 and located in the mounting cavity 101. The temperature measuring portion is arranged closer to the cartridge body 11 than the connecting portion, for detecting the first parameter of the cartridge body 11. The connecting portion is electrically connected to the plug. The plug is detachably plugged with the socket, so as to achieve the detachable electrical connection between the working environment sensor 2 and the information processing device 3.

[0069] In the embodiment, the temperature measuring portion of the working environment sensor 2 is arranged in the mounting cavity 101 and close to the cartridge body 11, so that the temperature measured by the temperature measuring portion of the working environment sensor 2 is closer to the temperature in the containing cavity. Moreover, the temperature measuring portion of the working environment sensor 2 is located in the mounting cavity 101, which is better protected and less likely to be disturbed by other environments or conditions. For example, the heat generated by the operation of other components in the image forming device 200 will not directly affect the temperature measurement of the temperature measuring portion. In addition, the working environment sensor 2 is arranged outside the main body 1 instead of extending into the containing cavity, which can prevent the toner from polluting the working environment sensor 2 and affecting the detection accuracy, and at the same time, the lead of the working environment sensor 2 does not need to be led out from the containing cavity to the outside, which can improve the sealing performance and reduce the risk of toner leakage.

[0070] Further, the socket is an integral structure of the information processing device 3, or the socket is an integral structure of the end cover 12, or the socket is an integral structure of the cartridge body 11. For example, the socket can be an integral structure of the base 111, or the socket can be an integral structure of the cover 112. The working environment sensor 2 is a temperature sensor, which is in a rod-shaped structure to facilitate insertion into the mounting cavity 101. Exemplarily, the working environment sensor 2 can be a thermistor or a thermocouple.

[0071] In some embodiments, when the communication module and the working environment sensor 2 are electrically connected with the same contact of the image forming apparatus, the communication module comprises a data terminal:

[0072] The working environment sensor 2 is electrically connected with the information processing device 3, and when the process cartridge 100 is installed at the predetermined position on the image forming apparatus 200, the working environment sensor 2 is electrically connected with the image forming apparatus 200 through the data terminal of the information processing device;

[0073] Or the process cartridge 100 comprises a first conductive member, a first end of the first conductive member is electrically connected with the working environment sensor 2, and a second end of the first conductive member is spaced apart from the data terminal of the information processing device 3. When the process cartridge 100 is installed at the predetermined position on the image forming apparatus 200, the second end of the first conductive member and the data terminal of the information processing device 3 are electrically connected with the same contact of the image forming apparatus 200, so that the working environment sensor 2 is electrically connected with the image forming apparatus 200 through the first conductive member. For example, when the process cartridge 100 is not installed on the image forming apparatus 200, the second end of the first conductive member and the data terminal of the information processing device 3 are spaced apart and not electrically connected; when the process cartridge 100 is installed at the predetermined position on the image forming apparatus 200, the second end of the first conductive member and the data terminal of the information processing device 3 are still in the state of being spaced apart, but the second end of the first conductive member and the data terminal of the information processing device 3 are both electrically connected with the same contact of the image forming apparatus 200, or when the process cartridge 100 is installed at the predetermined position on the image forming apparatus 200, the second end of the first conductive member contacts the data terminal of the information processing device 3, realizing the electrical connection between the second end of the first conductive member and the data terminal of the information processing device 3, and the data terminal of the information processing device 3 is electrically connected with the contact of the image forming apparatus 200, so that the working environment sensor 2 is electrically connected with the image forming apparatus 200 through the information processing device 3;

When the processing cartridge 100 is installed to the predetermined position on the image forming device 200, the second end of the second conductive member, the data terminal of the information processing device 3 and the same contact on the image forming device 200 are electrically connected. For example, the second end of the second conductive member contacts the data terminal of the information processing device 3, but the surface of the second end of the second conductive member contacting the data terminal of the information processing device 3 is an insulating surface, so that the second end of the second conductive member is not electrically connected with the data terminal of the information processing device 3, but when the processing cartridge is installed to the predetermined position on the image forming device 200, the second end of the second conductive member and the data terminal of the information processing device 3 are electrically connected with the same contact on the image forming device 200.

[0075] In some other embodiments, when the working environment sensor 2 is electrically connected with the information processing device 3, an input unit is provided on the information processing device 3, the input unit is electrically connected with the data terminal of the information processing device 3, and the working environment sensor 2 is electrically connected with the input unit, so that the working environment sensor 2 is electrically connected with the data terminal of the information processing device 3 through the input unit.

[0076] or the processing cartridge 100 further comprises a third conductive member, a first end of the third conductive member is electrically connected with the working environment sensor 2, and a second end of the third conductive member is electrically connected with the data terminal of the information processing device 3, so that the working environment sensor 2 is electrically connected with the data terminal of the information processing device 3 through the third conductive member. When the processing cartridge 100 is installed to the predetermined position on the image forming device 200, the working environment sensor 2 is electrically connected with the image forming device 200 through the data terminal of the information processing device 3, and the working environment sensor 2 can transmit the measured data to the image forming device 200 through the information processing device 3, without the need to provide new docking contacts on the processing cartridge 100 and the image forming device 200 respectively, so that the structure is simple and the cost is low.

[0077] In the present embodiment, the information processing device 3 is arranged on the end cover 12, and the working environment sensor 2 is arranged in the installation cavity 101 enclosed by the end cover 12 and the cartridge body 11. It can be understood that in other embodiments, the information processing device 3 and the working environment sensor 2 can also be arranged at other positions of the main body 1. For example, one of the information processing device 3 and the working environment sensor 2 is arranged on an imaging assembly including a photosensitive drum, and the other is arranged on a developing assembly including a developing roller; or the main body 1 includes a developer container for containing a developer and an imaging assembly including a photosensitive drum, one of the information processing device 3 and the working environment sensor 2 is arranged on the imaging assembly, and the other is arranged on the developer container; or the main body 1 includes a developer container for containing a developer and a developing assembly including a developing roller, one of the information processing device 3 and the working environment sensor 2 is arranged on the developing assembly, and the other is arranged on the developer container; or the main body 1 includes a developer container, a developing assembly, and an imaging assembly, the developer container is for containing a developer, the imaging assembly includes a photosensitive drum, and the developing assembly includes a developing roller, one of the information processing device 3 and the working environment sensor 2 is arranged on one of the developer container, the developing assembly, and the imaging assembly, and the other is arranged on another of the developer container, the developing assembly, and the imaging assembly; or the main body 1 includes a developer container for containing a developer, and the information processing device 3 and the working environment sensor 2 are arranged on the developer container; or the main body 1 includes an imaging assembly including a photosensitive drum, and the information processing device 3 and the working environment sensor 2 are arranged on the imaging assembly.

[0078] The present embodiment also discloses a detection method, including the following steps:

[0079] Obtaining a first parameter related to the processing cartridge 100;

[0080] Determining whether the first parameter or a second parameter obtained based on the first parameter meets an expectation;

[0081] Stopping the processing cartridge 100 from delivering the developer when the expectation is not met.

[0082] By detecting the first parameter related to the processing cartridge 100, when the first parameter or the second parameter obtained based on the first parameter does not meet the expectation, the image forming apparatus 200 stops the processing cartridge 100 from delivering the developer, preventing the processing cartridge 100 from causing the developer to be agglomerated and affecting the printing effect due to the internal environment parameter being too high or too low during the printing process.

[0083] Further, the above-mentioned stopping the processing cartridge 100 from delivering the developer when the expectation is not met further includes the following steps:

[0084] Turning on the temperature reduction and / or humidity reduction until the first parameter or the second parameter meets the expectation.

[0085] By the temperature reduction and / or humidity reduction, the environment of the process cartridge 100 can be improved to re-enter the standby state or the printing state.

[0086] Further, the judging whether the first parameter or the second parameter obtained based on the first parameter meets the expectation includes the following steps:

[0087] comparing the first parameter with a first preset parameter range, if the first parameter is not within the first preset parameter range, the first parameter does not meet the expectation;

[0088] or comparing the second parameter with a second preset parameter range, if the second parameter is not within the second preset parameter range, the second parameter does not meet the expectation.

[0089] Optionally, the process cartridge 100 stops delivering the developer based on different states of the image forming apparatus 200, which can have different situations:

[0090] For example, when the image forming apparatus 200 is in the standby state, if the first parameter or the second parameter obtained based on the first parameter does not meet the expectation, the process cartridge 100 remains not to deliver the developer without entering the printing state even if it needs to enter the printing state;

[0091] When the image forming apparatus 200 is in the printing state, if the first parameter or the second parameter obtained based on the first parameter does not meet the expectation, the process cartridge 100 changes from delivering the developer to not delivering the developer, or the process cartridge 100 remains not to deliver the developer.

[0092] It can be understood that there is a situation that the first parameter is higher or lower than the first preset parameter range, resulting in that the first parameter does not meet the expectation.

[0093] It can be understood that there is a situation that the second parameter is higher or lower than the second preset parameter range, resulting in that the second parameter does not meet the expectation.

[0094] Optionally, when the first parameter is higher than the first preset parameter range or the second parameter is higher than the second preset parameter range, the image forming apparatus 200 turns on the temperature reduction. The first preset parameter range and the second preset parameter range can be a fixed value, a set of at least two fixed values, or a numerical range, and the first parameter being higher than the first preset parameter range or the second parameter being higher than the second preset parameter range means that the first parameter is higher than an upper limit value of the first preset parameter range or the second parameter is higher than an upper limit value of the second preset parameter range.

[0095] Further, when the first parameter is higher than the first preset parameter range or the second parameter is higher than the second preset parameter range, the image forming apparatus 200 starts the cooling fan; or the image forming apparatus 200 increases the rotating speed of the cooling fan.

[0096] Further, when the first parameter is lower than the first preset parameter range or the second parameter is lower than the second preset parameter range, the image forming apparatus 200 stops the cooling fan or reduces the rotating speed of the cooling fan; or considering that the first parameter frequently exceeds or falls into the first preset parameter range, which may cause the cooling fan to be started or stopped or the rotating speed of the cooling fan to be adjusted too frequently, a reference parameter can also be set, the reference parameter is lower than the upper limit value of the first preset parameter range, and there is a certain gap between the reference parameter and the upper limit value, when the first parameter is lower than the reference parameter, the image forming apparatus 200 stops the cooling fan or reduces the rotating speed of the cooling fan. The second parameter affects the image forming apparatus 200 to stop the cooling fan or reduce the rotating speed of the cooling fan in the same way.

[0097] Exemplarily, in the process of the image forming apparatus 200 performing the image forming operation, when the temperature detected by the temperature sensor exceeds T1, the image forming apparatus 200 stops working, the cooling fan of the image forming apparatus 200 works, and the heat in the image forming apparatus 200 is taken out of the outside through air suction, so as to cool the image forming apparatus 200 for a certain time. After t1 time, it is confirmed whether the temperature detected by the temperature sensor is reduced to T2 or below, when it is confirmed that the temperature detected by the temperature sensor is reduced to T2 or below, the image forming apparatus 200 continues to perform the image forming operation, otherwise, the cooling operation is continued, and when it is confirmed that the temperature detected by the temperature sensor is reduced to T2 or below, the image forming apparatus 200 continues to perform the image forming operation.

[0098] Supplementarily, in the embodiment of the present application, the second parameter obtained based on the first parameter can be the same type or different type data as the first parameter, the numerical value of the first parameter and the second parameter can be the same or different, and the second parameter can also be calculated and generated based on the first parameter, the preset algorithm or the associated information, which is not limited in the embodiment of the present application. Exemplarily, the determination of the second parameter based on the first parameter can refer to the content of embodiment six.

For example, when the processing cartridge 100 is not installed on the image forming device 200, the second end of the first conductive member is spaced apart from the data terminal of the information processing device 3 and is not electrically connected with the data terminal of the information processing device 3; when the processing cartridge 100 is installed at the predetermined position on the image forming device 200, the second end of the first conductive member is still spaced apart from the data terminal of the information processing device 3, but the second end of the first conductive member and the data terminal of the information processing device 3 are respectively electrically connected with the same contact of the image forming device 200; or when the processing cartridge 100 is installed at the predetermined position on the image forming device 200, the second end of the first conductive member can be in contact with the data terminal of the information processing device 3, so that the second end of the first conductive member is electrically connected with the data terminal of the information processing device 3, and the data terminal of the information processing device 3 is electrically connected with the contact of the image forming device 200, so that the working environment sensor 2 is electrically connected with the image forming device 200 through the information processing device 3.

When the processing cartridge 100 is installed at the predetermined position on the image forming device 200, the second end of the second conductive member and the data terminal of the information processing device 3 are electrically connected with the same contact of the image forming device 200. For example, the second end of the second conductive member is in contact with the data terminal of the information processing device 3, but the surface of the second end of the second conductive member in contact with the data terminal of the information processing device 3 is the insulating surface, so that the second end of the second conductive member is not electrically connected with the data terminal of the information processing device 3, but when the processing cartridge 100 is installed at the predetermined position on the image forming device 200, the second end of the second conductive member and the data terminal of the information processing device 3 are electrically connected with the same contact of the image forming device 200.

The second parameter can also be calculated and generated based on the first parameter, a preset algorithm or associated information. The embodiment does not limit this, and for example, the determination of the second parameter based on the first parameter can refer to the content of Embodiment Six.

The working environment sensor 2 is at least partially located in the mounting cavity 101. The information processing device 3 can be mounted on the end cover 12, or can be mounted on the base body 111 or the upper cover 112.

[0126] In some embodiments, the working environment sensor 2 is installed in the first installation site 102, and the information processing device 3 is installed in the second installation site 103.

For example, the second end of the second conductive member is in contact with the data terminal of the information processing device 3, but the surface of the second end of the second conductive member in contact with the data terminal of the information processing device 3 is an insulating surface, so that the second end of the second conductive member is not electrically connected with the data terminal of the information processing device 3. However, when the processing cartridge 100 is mounted to the predetermined position on the image forming apparatus 200, the second end of the second conductive member and the data terminal of the information processing device 3 are electrically connected with the same contact on the image forming apparatus 200.

[0134] Embodiment five

[0135] The image forming operation needs to be performed in a suitable environment. If the environmental parameters are not as expected, for example, the temperature of the process cartridge is too high or the humidity is too high, which can cause the developer to be blocked and the developer to be transported abnormally. In addition, if the temperature and humidity inside the image forming device 200 are too high or too low, the imaging effect will be affected. The environmental parameters can be detected to ensure the accuracy of the detection. However, the working environment sensor 2 for detecting the environmental parameters can be erroneous or damaged, or although the working environment sensor 2 is working normally, the image forming device 200 provided with the working environment sensor 2 can have problems, which can cause misjudgment and affect the normal operation of the image forming operation.

[0136] To solve the above problems, the embodiments of the present application disclose that when the difference between the first parameter measured by the working environment sensor 2 or the second parameter obtained based on the first parameter and the internal environmental parameter measured by the internal environmental sensor in the image forming device 200 is not within the preset value range, the judgment of whether the first parameter or the second parameter obtained based on the first parameter is as expected is stopped. The measurement of the working environment sensor 2 can be checked by the internal environmental sensor in the image forming device 200. When the difference between the two is too large, it is considered that the working environment sensor 2 can have problems, or the environment in the image forming device 200 can have problems. The image forming device 200 stops the judgment of whether the first parameter or the second parameter obtained based on the first parameter is as expected, which can prevent misjudgment.

[0137] Further, when the difference between the first parameter measured by the working environment sensor 2 or the second parameter obtained based on the first parameter and the internal environmental parameter measured by the internal environmental sensor in the image forming device 200 is not within the preset value range, the judgment of whether the first parameter or the second parameter obtained based on the first parameter is as expected is stopped and the process cartridge stops conveying the developer.

[0138] Further, the detection method further comprises the following steps:

[0139] When the internal environmental parameters measured by the internal environmental sensor in the image forming device 200 in turn gradually increase in multiple detections, if the first parameter or the second parameter obtained based on the first parameter measured by the working environment sensor 2 in turn does not increase in multiple detections within the same time period, the image forming device 200 stops the judgment of whether the first parameter or the second parameter is as expected;

[0140] Or when the internal environmental parameters measured by the internal environmental sensor in the image forming device 200 in turn gradually decrease in multiple detections, if the first parameter or the second parameter obtained based on the first parameter measured by the working environment sensor 2 in turn does not decrease in multiple detections within the same time period, the image forming device 200 stops the judgment of whether the first parameter or the second parameter is as expected.

[0141] Generally, when the environmental parameter in the image forming apparatus 200 changes, the environmental parameter of the process cartridge 100 also changes accordingly, thus if the environmental parameter of the process cartridge 100 does not change with the internal environmental parameter measured by the internal environmental sensor, it is possible that the internal environmental sensor or the working environmental sensor 2 is abnormal, thus stopping the judgment of whether the first parameter or the second parameter meets the expectation can prevent misjudgment.

[0142] Optionally, the internal environmental sensor can be an environmental parameter sensor such as a temperature sensor, a humidity sensor, and the like. Further, the internal environmental sensor can be a thermistor, a thermocouple, and the like.

[0143] Optionally, when the internal environmental sensor in the image forming apparatus 200 measures the internal environmental parameter gradually increasing in the multiple detections in sequence, at least the following cases exist:

[0144] In all detection results in the multiple detections, at least two detection results are equal, but the rest of the detection results gradually increase;

[0145] or in all detection results in the multiple detections, the detection result of the latter is greater than the detection result of the former;

[0146] or in all detection results in the multiple detections, there are two adjacent detection results, the detection result of the latter is less than the detection result of the former, but the difference between the two detection results is within the detection error range, and at least one detection result in the latter is greater than at least one detection result in the former;

[0147] or the multiple detection results are segmented in sequence according to the detection time, and the average value of the detection results in different segments is calculated, the average value in the segment of the latter detection time is greater than the average value in the segment of the former detection time.

[0148] Optionally, when the internal environmental sensor in the image forming apparatus 200 measures the internal environmental parameter gradually decreasing in the multiple detections in sequence, at least the following cases exist:

[0149] In all detection results in the multiple detections, at least two detection results are equal, but the rest of the detection results gradually decrease;

[0150] or in all detection results in the multiple detections, the detection result of the latter is less than the detection result of the former;

[0151] or in all detection results in the multiple detections, there are two adjacent detection results, the detection result of the latter is greater than the detection result of the former, but the difference between the two detection results is within the detection error range, and at least one detection result in the latter is less than at least one detection result in the former;

[0152] Or the multiple detection results are sequentially segmented according to detection time, and the average values of the detection results in different segments are calculated, and the average value in the segment later in detection time is less than the average value in the segment earlier in detection time.

[0153] It can be understood that the method in the embodiment can be applied to the above-mentioned embodiments one to four, and the method in the embodiment is prior to the method in the embodiment one.

[0154] Embodiment six

[0155] The image forming apparatus 200 needs to collect or output an electric signal for realizing information interaction between the process cartridge 100 and the body of the image forming apparatus 200 during the image forming operation, but the electric signal may be inaccurate or unreliable in the process of acquisition or transmission due to reasons such as damage of circuit or element, poor contact, and low precision, which will affect the information interaction.

[0156] The application discloses a process cartridge for being detachably installed in an image forming apparatus, comprising a body 1, a working element, and an information processing device 3, the working element is arranged on the body 1 and is used for detecting or acquiring a first parameter related to the process cartridge 100, the image forming apparatus 200 can acquire the first parameter, the information processing device 3 is arranged on the body 1 and is used for transmitting a correction coefficient to the image forming apparatus 200, the correction coefficient is used for correcting the first parameter to obtain a second parameter. That is, by using the correction coefficient to correct the first parameter, the first parameter affected by reasons such as signal interference, poor contact, and low precision can be corrected, and the accuracy of signal acquisition or transmission is improved.

[0157] Optionally, the working element is a working environment sensor 2, and the working environment sensor 2 is used for detecting the first parameter related to the process cartridge 100, and the image forming apparatus 200 acquires the first parameter.

[0158] Or the working element is a fixed resistor, and the working element is used for enabling the image forming apparatus 200 to acquire the first parameter.

[0159] Or the working element is an adjustable resistor, and the working element is used for enabling the image forming apparatus 200 to acquire the first parameter.

[0160] When the working element is the working environment sensor 2, the image forming apparatus 200 can acquire environmental information such as temperature, humidity, and light intensity of the process cartridge 100 through the working environment sensor 2, but the acquired environmental information may have errors and affect the judgment of the image forming apparatus 2, which may lead to misjudgment; when the working element is the fixed resistor or the adjustable resistor, the image forming apparatus 200 can acquire electric signals such as current and voltage of the process cartridge 100 through the fixed resistor or the adjustable resistor, and the electric signals may also deviate and affect the judgment of the image forming apparatus 2, which may lead to misjudgment.

[0161] The following is further illustrated by setting the working element as the working environment sensor 2. It can be understood that the working element can also be set as a fixed resistor or an adjustable resistor, or different kinds of working environment sensors 2 cooperate with each other, or the working environment sensor cooperates with the fixed resistor or the adjustable resistor:

[0162] When performing an image forming operation, it is necessary to detect the working environment of the process cartridge by using the working environment sensor 2. If the detection accuracy of the working environment sensor 2 is low, the detection error of the environmental parameter will be large. If the detection accuracy of the working environment sensor 2 is too high, the cost will be increased. For example, a thermistor can be used to measure the temperature inside the image forming device 200, and cooling treatment can be performed when the temperature is too high, so as to avoid a series of problems caused by the temperature rise inside the image forming device 200. However, the temperature measurement accuracy of the general thermistor is not high, and there is a certain error, which can make the image forming device 200 unable to accurately detect the temperature and start cooling in time, thereby causing the print count of each machine to be different, or causing caking when the temperature exceeds the predetermined temperature, thereby affecting the normal work of the image forming device 200. However, the use of a high-precision thermistor will increase the cost and cause the use cost to be too high.

[0163] In order to solve the above problems, the embodiment of the present application discloses a process cartridge for being detachably installed in an image forming device 200. The process cartridge comprises a main body 1, a working environment sensor 2 and an information processing device 3.

The correction coefficient is used for correcting the first parameter measured by the working environment sensor 2 to obtain a second parameter. When detecting the environmental parameter of the process cartridge, the image forming device 200 can correct the first parameter measured by the working environment sensor 2 based on the correction coefficient to obtain the second parameter. The present application improves the detection accuracy by correcting the first parameter.

[0207] Embodiment seven

[0208] As shown in the above embodiments, based on the above-mentioned embodiments, the embodiments of the present application also disclose a detection circuit for mounting on the processing cartridge 100, the processing cartridge 100 being used for being detachably mounted on the image forming device 200, the detection circuit comprising: Figure 11 The detection unit 31 is used for outputting a first parameter related to the processing cartridge 100;

[0209] The information feedback unit 32 is electrically connected with the detection unit 31, and provides feedback information for the image forming device 200 to acquire according to the connection state of the detection unit 31; wherein the connection state of the detection unit 31 and the information feedback unit 32 comprises a first state and a second state;

[0210] The control unit 33 is configured to control the connection state of the detection unit 31 and the information feedback unit 32 to switch between the first state and the second state according to the switching information output by the image forming device 200;

[0211] In the first state, the feedback information is related to the first parameter, and the image forming device 200 can acquire the first parameter based on the feedback information; in the second state, the feedback information is irrelevant to the first parameter.

[0212] Compared with the prior art, by controlling the state switching between the detection unit 31 and the information feedback unit 32 through the control unit 33, the electrical connection between the information feedback unit 32 and the detection unit 31 is switched between the first state and the second state, and the feedback information is changed from being related to the first parameter to being irrelevant to the first parameter. Based on the change of the feedback information, the information feedback unit 32 can be detected, and the result of the detection can be used to judge whether the condition of the information feedback unit 32 meets the expectation or not. If it meets, the image forming device 200 acquires the first parameter accurately, if it does not meet, the process of the image forming device 200 acquiring the first parameter is affected by the information feedback unit 32 and there is a deviation, so the reliability of information transmission can be detected.

[0213] Optionally, in the first state and the second state, the feedback information is different.

[0214]

[0215] ​Optionally, the feedback information is related to the first parameter, and the feedback information can be used to calculate or obtain the first parameter.

[0216] The feedback information is not related to the first parameter, and the feedback information cannot be used to calculate or obtain the first parameter.

[0217] The first parameter related to the foregoing is introduced in the same way as in Example One, and will not be repeated here.

[0218] Optionally, in the first state, the detection unit 31 is electrically connected with the information feedback unit 32;

[0219] In the second state, the detection unit 31 is electrically disconnected with the information feedback unit 32,

[0220] Or the detection unit 31 is short-circuited,

[0221] Or the port corresponding to the end of the detection unit 31 for electrically connecting the information feedback unit 32 is configured as a high resistance state.

[0222] For example, in the process of laser printing, there is heating or friction to cause the toner cartridge 100 to heat up, and the toner stored in the toner cartridge 100 will be affected by the environmental parameters, such as temperature. If the environmental parameters of the toner cartridge 100 are too high or too low, it may cause the toner stored in the toner cartridge 100 to be agglomerated, affecting the delivery of the toner and the printing effect. Therefore, it is necessary to monitor the environmental parameters, such as temperature, of the toner cartridge 100, but if the circuit or element for detecting the environmental parameters fails, it will cause the detection result to deviate, which will affect the normal printing.

[0223] Therefore, a detection circuit can be used, which is installed in the toner cartridge 100, and the toner cartridge 100 is used to be detachably installed in the image forming device 200, which comprises:

[0224] The detection unit 31, one end of the detection unit 31 is used to electrically connect the working element, and the other end of the detection unit 31 is used to electrically connect the information feedback unit 32, and access the image forming device 200 through the information feedback unit 32;

[0225] The control unit 33 is configured to receive information of the image forming device 200 and control the detection unit 31 and the information feedback unit 32 to have a first state and a second state, wherein:

[0226] In the first state, the information feedback unit 32 accesses the first circuit unit, and the first circuit unit comprises the detection unit 31, and the detection unit 31 is electrically connected with the information feedback unit 32;

[0227] In the second state, the information feedback unit 32 accesses the second circuit unit, wherein the first circuit unit is different from the second circuit unit;

[0228] When the information feedback unit 32 is connected to the first circuit unit, the image forming apparatus 200 can obtain the first parameter related to the process cartridge 100 based on the working element.

[0229] When the information feedback unit 32 is connected to the first circuit unit, whether the information feedback unit 32 is as expected will affect the accuracy of the image forming apparatus 200 in obtaining the first parameter, and when the information feedback unit 32 is not as expected, the image forming apparatus 200 will not obtain the first parameter accurately, and when the information feedback unit 32 is connected to the second circuit unit, the feedback information will change, and the change in the feedback information before and after can be used to determine whether the information feedback unit 32 is as expected.

[0230] The control unit 33 controls the state switching between the detection unit 31 and the information feedback unit 32, so that the information feedback unit 32 is electrically connected to the first circuit unit where the detection unit 31 is located, and the information feedback unit 32 is connected to the second circuit unit different from the first circuit unit, so that the voltage division at the information feedback unit 32 is changed, that is, the feedback information is changed. By changing the voltage division, the resistance of the information feedback unit 32 can be calculated, and whether the resistance of the information feedback unit 32 is as expected can be determined. If it is as expected, it means that the first parameter related to the process cartridge 100 obtained based on the working element is accurate, and if it is not as expected, it means that the first parameter related to the process cartridge 100 obtained based on the working element has a deviation.

[0231] Alternatively, the introduction of the working element can refer to the foregoing embodiments, which will not be described here

[0232] Alternatively, if the resistance of the information feedback unit 32 detected in the second state is not within the expected resistance range, it is determined that the resistance of the information feedback unit 32 is not as expected, and whether the first parameter or the second parameter obtained based on the first parameter is as expected is not determined. At this time, since the resistance of the information feedback unit 32 is detected to be abnormal, it will affect the accuracy of the first parameter or the second parameter, so whether the first parameter or the second parameter is as expected is not determined to prevent misjudgment.

[0233] Alternatively, the first parameter is obtained by detecting the common voltage division of the information feedback unit 32, the detection unit 31 and / or the working element. Of course, in other embodiments, the working element can also deliver the first parameter to the image forming apparatus 200 after obtaining the first parameter.

[0239] Or the first circuit unit and the second circuit unit have a part of the circuit in common, for example, the first circuit unit and the second circuit unit are grounded through the same contact or wire.

[0240] Optionally, in the first state, the detection unit 31 is electrically connected with the information feedback unit 32.

[0241] In the second state, the detection unit 31 is disconnected with the information feedback unit 32,

[0242] Or the detection unit 31 is electrically connected with the information feedback unit 32 but the detection unit 31 is short-circuited.

[0243] Or the port corresponding to the end of the detection unit 31 for electrical connection with the information feedback unit 32 is configured as a high resistance state. At this time, the voltage division of the information feedback unit 32 in the second state will change, and the resistance of the information feedback unit 32 can be calculated by the change of the voltage division of the information feedback unit 32 when switching between the first state and the second state.

[0244] Optionally, the resistance of the information feedback unit 32 can be detected in the second state, and the resistance of the information feedback unit 32 can be used to obtain the first parameter in the first state.

[0245] Specifically, if the resistance of the information feedback unit 32 detected in the second state is not within the expected value range, it is determined that the resistance of the information feedback unit 32 does not meet the expectation, and it is determined that the first parameter or the second parameter does not meet the expectation.

[0246] Optionally, when the detection unit 31 is disconnected from the information feedback unit 32 in the second state, the detection circuit further comprises a first matching circuit, one end of the first matching circuit being configured to be electrically connected to the information feedback unit 32, and the other end of the first matching circuit being configured to be grounded; the control unit 33 comprises a first switching switch, the first switching switch being connected between the information feedback unit 32 and the first matching circuit and between the information feedback unit 32 and the detection unit 31, and being configured to electrically connect the information feedback unit 32 to the first matching circuit or the detection unit 31 by switching operation; and the first controller is configured to control the first switching switch to perform corresponding switching operation according to switching information output by the image forming apparatus 200.

[0254] The control unit 33 comprises:

[0255] a third controller, the third controller being electrically connected with the information feedback unit 32, the second cooperating circuit and the detection unit 31 respectively, and the third controller being configured to configure the electrical connection end of the detection unit 31 in a high-impedance state according to the switching information output by the image forming apparatus 200. Two ports of the third controller are respectively used for electrical connection with the second cooperating circuit and the detection unit 31, in the second state, the port of the third controller corresponding to the detection unit 31 is configured in a high-impedance state, and the information feedback unit 32 is directly grounded. Further, the second circuit unit further comprises the second cooperating circuit.

[0256] Optionally, the information feedback unit 32 comprises a first voltage division module 32a, the first voltage division module 32a being used for electrical connection with the detection unit 31, and the side of the first voltage division module 32a away from the detection unit 31 being used for potential detection by the image forming apparatus 200 to obtain feedback information. Wherein, the image forming apparatus 200 obtains the first parameter by detecting the potential value of the end of the first voltage division module 32a away from the detection unit 31.

[0257] Further, the first voltage division module 32a is a resistor.

[0258] Optionally, the detection unit 31 comprises a working element, the working element being used for detecting or obtaining the first parameter related to the process cartridge 100.

[0259] Or the detection unit 31 is used for electrical connection with a working element, the working element being used for detecting or obtaining the first parameter related to the process cartridge 100, and the working element being used for enabling the image forming apparatus 200 to obtain the first parameter through the detection unit 31.

[0260] Furthermore, when the working element is the working environment sensor 2, the working environment sensor 2 includes a temperature sensor.

[0261] Specifically, such as Figure 11 As shown, the image forming apparatus 200 includes a potential detection terminal 209, a power supply 210, and a second voltage divider module 211. The power supply 210, the second voltage divider module 211, and the first voltage divider module 32a are connected in series. The first voltage divider module 32a is electrically connected to the working environment sensor 2 and the second switch 33a, respectively, so that the working environment sensor 2 and the second switch 33a are connected in parallel. The end of the working environment sensor 2 and the second switch 33a away from the working environment sensor 2 is used for grounding. The potential detection terminal 209 is used to detect the potential between the second voltage divider module 211 and the first voltage divider module 32a. When the second switch 33a is open, the second voltage divider module 211, the first voltage divider module 32a, and the working environment sensor 2 are connected in sequence. At this time, the potential detection terminal 209 can obtain the common voltage division of the first voltage divider module 32a and the working environment sensor 2, and obtain the detection value of the working environment sensor 2 from the potential obtained by the potential detection terminal 209.

[0262] For example, the first voltage divider module 32a is a resistor R1, the second voltage divider module 211 is a resistor R2, the working environment sensor 2 is a thermistor R3 for temperature measurement, the second switching switch 33a is a transistor Q1, and the power supply 210 is the circuit's supply voltage VCC. If the standard value of R1 is set to 10Ω, the standard value of R2 is 20Ω, and the resistance of the thermistor R3 at 30℃ is 10Ω, ignoring the voltage division when Q1 is on, when R1 = 10Ω and Q1 is off, the potential value obtained by the potential detection terminal 209 is VCC*(R1+R3) / (R1+R2+R3) = VCC*(10+10) / (10+20+10) = 0.5VCC.

[0263] Since the temperature detection is set based on a standard R1 value of 10Ω, for the image forming apparatus 200, when the potential value at the potential detection terminal 209 is 0.5VCC, the detected temperature value is considered to be 30℃.

[0264] If R1 malfunctions and its actual value is 5Ω instead of the standard 10Ω, at the same temperature (30℃), R3 will still be 10Ω and R2 will be 20Ω. In this case, the potential value obtained by the potential detection terminal 209 will be V = VCC * (5 + 10) / (5 + 20 + 10) = 3 / 7VCC, which is not equal to 0.5VCC. Based on the judgment logic originally set by the image forming apparatus 200, the temperature value obtained by the image forming apparatus 200 through R3 will not be 30℃, but the actual temperature should be 30℃. That is, the temperature obtained by the image forming apparatus 200 is different from the actual temperature, and an error has occurred.
