Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, and particularly relates to a developer container and a printing equipment. BACKGROUND

[0002] The printing equipment is one of daily office supplies, and usually has functions of printing, copying and scanning. In the printing equipment of laser printing mode, the developing device is one of core components in the printing equipment, and stores the developer inside. The developer needs to be replaced or supplemented after being consumed. At present, there are many types of printing equipment, and the developing devices adapted are various. Therefore, the detection mechanism needs to be arranged on the printing equipment to identify the developing device installed, so as to judge whether the developing device can meet the use requirement of the printing equipment, and avoid damage of the printing equipment caused by the developing device not being adapted.

[0003] The detected structure on the existing developing device is usually a counting gear exposed outside the developing device and having a part protruding outward. The counting gear has a plurality of detection protrusions arranged in the circumferential direction around the axis direction. After the developing device is installed into the printing equipment, the counting gear is driven to rotate, and the detection protrusions are sequentially contacted with the detection mechanism to trigger the detection signal.

[0004] However, since the detection protrusions need to protrude outward to contact the detection mechanism, the protruding part of the counting gear is easy to collide with the side wall or the detection mechanism in the printing equipment during the installation of the developing device, and the printing equipment or the detection mechanism can be damaged if the user disassembles with too much force.

DETAILED DESCRIPTION

[0039] The embodiments of the present application will be described in detail below with reference to the drawings and examples, so that the application can be better understood and implemented. It should be noted that these specific descriptions are only to make the present application more easily and clearly understood by those skilled in the art, and are not a limiting interpretation of the present application; for example, the first, second, etc. mentioned in the embodiments of the present application are not a limitation, but only a serial number for expressing a plurality of same or similar devices or mechanisms, and those skilled in the art can adjust the serial number for the convenience of expression or the arrangement of technical solutions; and the alternative solutions of some mechanisms in different embodiments can also be applied to other same or similar devices or mechanisms; and as long as there is no conflict, the various embodiments of the present application and the various features in each embodiment can be combined with each other, and the formed technical solutions are within the protection scope of the present application.

[0040] The technical solutions of the present application will be described in detail below with reference to the drawings and specific examples.

[0041] The embodiments of the present application provide a printing device, referring to Figure 1 , including a device body 1 and a paper box 11, a pickup assembly 12, a conveying assembly 13, a transfer assembly 14, a developing assembly 15, a scanning assembly 16, a fixing assembly 17 and a paper discharge assembly 18 arranged in the device body 1, the device body 1 is provided with a paper conveying path, the paper box 11 is stacked with paper for printing, the pickup assembly 12 includes a pickup roller, the pickup roller is in contact with the stacked paper and sends the paper into the paper conveying path, the conveying assembly 13 includes a correction roller and a paper feed roller, the correction roller is used to correct the position of the paper in the paper conveying path, and the paper feed roller is used to transmit the paper in the paper conveying path, the developing assembly 15 forms an image composed of a developing agent inside and transfers the image to the transfer assembly 14, the transfer assembly 14 transfers the image in the paper conveying path, after the paper obtains the image, it is further conveyed to the fixing assembly 17, the fixing assembly 17 fixes the image on the surface of the paper by heating, and the paper after printing is finally discharged to the outside of the device body 1 by the paper discharge assembly 18.

[0042] The scanning assembly 16 includes a laser emitting unit and an optical member for deflecting the laser emitted by the laser emitting unit, and the optical member can be composed of a plurality of optical components, the laser is deflected to the developing assembly 15 for the imaging process of the developing assembly 15. Referring to Figure 2 , the developing assembly 15 includes a photosensitive member 20, which has a photosensitive drum 21 with a photosensitive surface, the laser is deflected to the photosensitive surface to form a latent electrostatic image, and the developing agent forms an image by using the latent electrostatic image.

[0043] The prior art count gear structure has a plurality of detection protrusions, each detection protrusion represents a detection signal, and the width of the detection protrusion determines the information time length. When the detection component on the device body detects the count gear, each detection protrusion triggers the detection component to generate a detection signal, and the number of detection signals and the time length of the corresponding information represent the model of the corresponding developing assembly. In this structure, the detection component usually sets an active detection rod which can trigger the detection signal inside the device body. When the developing assembly is installed in the printing device, the detection rod will stay in the moving track of the detection protrusion on the count gear. For example, in the prior art of CN107305333B, the protrusion is transformed between touching and not touching the trigger rod of the electrophotographic imaging device under the power of the transmission gear, thereby achieving counting, but this structure is not reliable. The trigger rod, i.e. the aforementioned detection rod, may collide with the outside wall of the installation position when the developing device is installed, causing damage. Moreover, in this detection method, each protrusion, i.e. the part driving the trigger rod, has a limited number and triggering time, which has a large design defect and is difficult to meet the design requirements of various existing device models.

[0044] Therefore, as shown in Figures 2 to 12 The developing assembly in the embodiment of the present application includes a developer container, which includes a box body 100, a first roller 200, a cover component 300, a transmission component 400, and a trigger component 500. The box body 100 has a cavity for storing the developer and a powder outlet 110 communicating with the cavity. The first roller 200 is rotatably arranged on the powder outlet 110 and used to transmit the developer outside the box body 100. The box body 100 has a first side and a second side in the axial direction of the first roller 200. The cover component 300 is fixed to the first side by screw connection, buckle connection or other detachable connection methods, and forms a receiving space with the side wall of the first side, which can accommodate the transmission component 400 and other components. The transmission component 400 is designed as a drive gear set in this embodiment, which includes a first gear 410, a second gear 420, and a transmission gear 430. The first gear 410 is used to drive the first roller 200 to rotate. The second gear 420 is used to receive external driving force from the device body to drive the entire drive gear set to operate. The transmission gear 430 is used to cooperate with the trigger component 500.

[0045] The developing assembly also includes a photosensitive member 20, as shown in Figure 2The photosensitive member 20 can be arranged in the developer container to form an integral structure, or can be detachably assembled with the developer container to form a split structure, wherein the photosensitive member 20 comprises a housing 22, and a photosensitive drum 21 and a charging roller 23 rotatably arranged in the housing 22, the charging roller 23 being used to charge the surface of the photosensitive drum 21, the surface of the first roller 200 being in abutting contact with the surface of the photosensitive drum 21, in the imaging process, after the charging roller 23 charges the surface of the photosensitive drum 21, the latent image formed on the photosensitive drum 21 by the scanning assembly forms a developer image after receiving the developer from the first roller 200, and the developer image is transferred to the printing medium by the transfer assembly.

[0046] The trigger component 500 is used to trigger the detection component in the device body, so as to form detection information capable of identifying the corresponding model, comprising a rotating member 510, a sensed member 520, a first elastic member 530 and a second elastic member 540, the rotating member 510 is used to receive the driving force from the transmission component 400 and selectively transfer the driving force to the sensed member 520, specifically, the rotating member 510 is rotatably connected to the box body 100 and is received between the cover component 300 and the first side, i.e. inside the receiving space, and is protected by the cover component 300, the rotating member 510 comprises a driving force transmission member 511 capable of engaging with the transmission gear 430 and rotating around a rotating axis, the driving force transmission member 511 has a circumferential surface arranged axially around the rotating axis, and the circumferential surface has at least one driving tooth portion 512, each driving tooth portion 512 is composed of a plurality of teeth. Wherein the rotating axis around which the driving force transmission member 511 rotates is a first axis, and the first axis is parallel to the second axis around which the first roller 200 rotates, and both are along the length direction of the cover body.

[0047] The sensed member 520 comprises a base body 521 and a sensed assembly arranged on the base body 521, the base body 521 is relatively fixed on the cover component 300 or the box body 100 by means of buckle, screw connection or the like, the sensed assembly comprises a slider 522 movably arranged on the base body 521 and a movable plate 523 movably arranged on the slider 522, the slider 522 can reciprocate on the base body 521 along a first track, and has a connecting tooth portion 524 located on the moving track of the driving tooth portion 512, and the connecting tooth portion 524 located on the moving track of the driving tooth portion 512 specifically means that at least one tooth is arranged on the connecting tooth portion 524 at the position of the moving track of the driving tooth portion 512 when the slider 522 is located at the initial position, for example Figure 10 the position P in the figure, the slider 522 moves along the first direction (such as Figure 8During the movement in the direction U) of the moving direction, the connecting tooth portion 524 is arranged in sequence along the moving direction, wherein the tooth located at the front end in the moving direction is the first tooth, and the tooth located at the rear end in the moving direction is the second tooth. At the starting position, since the first tooth is located on the moving trajectory of the driving tooth portion 512, when the driving force transmission member 511 rotates along its rotation direction W, the front end of the driving tooth portion 512 contacts the first tooth to push the slider 522 to move forward in the first direction until the connecting tooth portion 524 is disengaged from the driving tooth portion 512.

[0048] The first track includes the sensing area and the non-sensing area, and the initial position is set on the non-sensing area. Figure 8 In the area A, the movable plate 523 cannot be detected by the detection component in the area A, and the sensing area is as follows Figure 8 In area B, the movable plate 523 is within the detection range of the detection component in area B, triggering the detection component and causing it to generate a corresponding detection signal. In this embodiment, the detection component can be set as a photoelectric sensor, which detects the movable plate 523 by emitting detection light. This detection method is a non-contact detection method, replacing the contact collision interference structure in the prior art. The first elastic member 530 is used to pull the slider 522 from the sensing area to the non-sensing area. One end of the first elastic member 530 is connected to the base 521, the cover member 300 or the box body 100, and the other end is connected to the slider 522 as a force-applying end to provide a first elastic force in the opposite direction of the first direction. When the connecting tooth portion 524 is disengaged from the driving tooth portion 512 or there is no other structure on the driving force transmission member 511 that allows the slider 522 to stay in the sensing area, the first elastic force pulls the slider 522 in the opposite direction of the first direction to return to the initial position. The second elastic member is used to move the movable plate 523 from the first position 523a to the second position 523b. The first position 523a and the second position 523b are as follows. Figure 10 As shown, the second position 523b is further away from the first side than the first position 523a, that is, in the axis direction (whether the first axis or the second axis), the second position 523b is more protruding outside the box body 100 than the first position 523a. Figure 13 The movable plate 523 at the second position 523b coincides with the area C in the first direction, but the movable plate 523 at the second position 523b is offset from the area C in the first direction, so that if the movable plate 523 is moved along the first direction in the second position 523b, it can be moved to the position of the area C, thereby being detected by the detection component. If it is moved along the first direction in the first position 523a, it cannot be moved to the position of the area C, and cannot be detected by the detection component. During the installation process of the developing assembly in the device body, the direction perpendicular to the axial direction and biased towards the first direction (such as Figure 8 andFigure 13 The installation is performed in the direction V in the figure, thus, the area C, i.e. the detection area, will not be in the moving direction of the movable plate 523 in the first position 523a, but in the moving direction of the movable plate 523 in the second position 523b.

[0049] The base 521 has a receiving stop 521a on the non-sensing area, when the slider 522 is in the non-sensing area, at least in the initial position in the non-sensing area, the receiving stop 521a blocks the movable plate 523 to be in the first position 523a; when the slider 522 is in the sensing area, the movable plate 523 will be in the second position 523b under the action of the second elastic member 540. Thus, the receiving stop 521a makes the movable plate 523 in the initial position be in the first position 523a, thus, during the installation of the developing assembly, the movable plate 523 in the first position 523a will not stretch out into the detection area to touch the detection member, preventing damage, and after the installation of the developing assembly is completed, if the slider 522 moves to the sensing area along the first track, the movable plate 523 will be elastically stretched out to the second position 523b to enter the area C, thus being detected by the detection member.

[0050] In the implementation, refer to Figures 3 to 13, the driving tooth portion 512 rotates along with the driving force transmission member 511 in a specified direction, i.e. direction W, engages the connecting tooth portion 524 to transmit driving force to the slider 522, so that the slider 522 is moved from the non-sensing area to the sensing area, and when the slider 522 leaves the non-sensing area, the second elastic member 540 pushes the movable plate 523 to move from the first position 523a to the second position 523b, which is exposed in the detection area and is sensed by the detection component, thereby triggering a detection signal. When there is only one driving tooth portion 512, the detection signal is triggered only once when the driving force transmission member 511 rotates one revolution. If there are two or more driving tooth portions 512, the same number of detection signals will be triggered when the driving force transmission member 511 rotates one revolution. In the detection duration of each detection signal, the width of the movable plate 523 in the first direction can be combined with the circumferential length of the driving tooth portion 512 to design, for example, in the case of a wide movable plate 523, there will be a critical point on the detection area that matches the sensing area, and when the movable plate 523 passes through the critical point, it can trigger the detection component to form a detection signal. Therefore, the length of time the movable plate 523 stays in the detection area can be determined by the engagement time of the driving tooth portion 512 with the connecting tooth portion 524. The longer the engagement time, the longer the corresponding detection signal. In combination with the triggering mode design of the number and length of the driving tooth portion 512, the signal transmission form can be concentrated on the transmission mode of the driving force transmission member 511. When the driving force transmission member 511 selectively drives the slider 522 with a driving tooth portion 512, a detection signal is generated, without the need for additional independent design of multiple detection components to trigger the detection component. The structure is more stable and reliable than the existing count gear design, can meet the adaptation requirements of various models, and can more accurately identify the model specifications that can be adapted, especially for a machine that can adapt to multiple models. The developing device structure may be divided into large capacity, ordinary capacity or small capacity and other multi-model structures according to user needs. This design can achieve accurate detection without additional design of detection components, does not occupy additional design space, and shortens the size of the developing assembly.

[0051] In one embodiment, referring to Figure 2 The distance from the first side of the movable plate 523 in the second position 523b to the farthest end is greater than the distance from the first side of any other part of the developer container to the farthest end. Figure 1For example, when the slider 522 is in the sensing area and the movable plate 523 is moved to the second position 523b, the movable plate 523 is located at a position point P in the axial direction farthest from the cartridge 100. The position point P is farthest from any point on the toner container, such as the base 521 portion outside the movable plate 523 in the present embodiment or the second gear 420, but neither of the two portions exceeds the movable plate 523 in the second position 523b. Thus, neither of the two portions falls into the first direction within the detection area C, i.e., the detection area. Specifically, referring to Figure 13 When the developing assembly is installed into the corresponding assembly card slot in the device body along the direction V, because the detection area is not in the installation direction of all the structures of the developing assembly (because the movable plate 523 is in the first position 523a), the corresponding detection components in the detection area will not interfere with any structure on the developing assembly in the direction, thereby forming effective protection.

[0052] In another embodiment, referring to Figure 5 and Figure 8 The first trajectory is perpendicular to the rotation axis of the first roller 200, i.e., in the present embodiment, the first trajectory is arranged along the first direction, and the first direction is perpendicular to the axial direction. At this time, the slider 522 translates along the direction parallel to the side wall of the first side during the movement, thereby ensuring that the axial direction of the developing assembly remains consistent during the movement of the slider 522, which is beneficial to the compactness of the overall structure and the rational use of the axial dimension space.

[0053] The movable plate 523 is rotationally arranged on the slider 522, and the rotation axis (third axis) thereof is perpendicular to the first trajectory. The movable plate 523 is arranged with the contact surface 5231 away from the first side. The contact surface 5231 is inclined away from the first side along the first trajectory when the movable plate 523 is in the second position 523b. Referring to Figure 12 and combining Figure 8The third axis is located close to the non-sensing area. When the movable plate 523 is separated from the receiving baffle, it rotates around the third axis away from the first side under the action of the second elastic member 540. At this time, the contact surface 5231 is offset in the first direction away from the first side. The distance between the receiving baffle 521a and the first side is greater than the shortest distance between the contact surface 5231 and the second side when the movable plate 523 is in the second position 523b. Therefore, when the slider 522 moves from the sensing area to the non-sensing area under the action of the first elastic member 530, the contact surface 5231 as the contact part with the receiving baffle 521a is tilted to make the movable plate 523 rotate around the third axis towards the first side, so that the movable plate 523 is reset from the second position 523b to the first position 523a. The elastic force of the first elastic member 530 acting on the slider 522 is greater than the friction force generated when the contact surface 5231 contacts the receiving baffle 521a, so that the movable plate 523 can be received back into the base 521 and reset to the first position 523a. Through this structural design, the movable plate 523 can conveniently realize the automatic outward swinging action in the detection direction, i.e., the first direction, and the reset receiving process in the opposite direction of the first direction. The mechanical structure realizes accurate transmission of detection information and provides good protection for the movable plate 523. The structure is simple and reliable. In addition, the movable plate 523 can also be linearly arranged along the axis direction on the slider 522. The contact surface 5231 is an inclined edge located at the edge of the movable plate 523, which can also achieve the above effects and is within the scope of the present application.

[0054] Further, two ends of the first elastic member 530 are located between the slider 522 and the base 521, providing a first force in the first direction between the two, so that the slider 522 always maintains a movement tendency in the opposite direction of the first direction relative to the base 521 under the first force, thereby resetting to the initial position of the non-sensing area when the driving teeth 512 and other components on the driving force transmission member 511 do not limit the slider 522; two ends of the second elastic member 540 are located between the slider 522 and the movable plate 523, providing a second force in the second direction between the two, so that the movable plate 523 always maintains a movement tendency in the direction away from the first side relative to the slider 522 under the second force, thereby extending from the base 521 to reach the second position 523b when the receiving stop 521a no longer blocks the movable plate 523. Wherein, the first direction is parallel to the first track, and the second direction is perpendicular to the first direction, so that the first direction is along the side wall direction of the box body 100, and the second direction is along the axis direction, the first force and the second force in the action directions are perpendicular to each other, and basically do not affect each other, which can ensure the action efficiency of each other, and make the internal structure of the trigger member 500 compact and reliable, and not easy to be affected by force imbalance. Specifically, the base 521 has a first protruding column 521b, one end of the first elastic member 530 is sleeved in the first protruding column 521b, and the other end is pressed against the inner side wall of the slider 522. The slider 522 has a second protruding column 5232 on the inner side wall in the axis direction, one end of the second elastic member 540 is sleeved in the second protruding column 5232, and the other end is pressed against the movable plate 523, thereby generating the first force and the second force.

[0055] In another embodiment, the driving force transmission member 511 comprises synchronously arranged first and second rotating discs 511a and 511b. The first rotating disc 511a is circumferentially provided with a transmission tooth portion 513 for engaging with the transmission gear 430 and a disengagement portion 514 adjacent to the transmission tooth portion 513. The transmission tooth portion 513 drives the first rotating disc 511a to rotate the driving force transmission member 511 as a whole when engaging with the transmission gear 430, and the first rotating disc 511a disengages from the transmission gear 430 when the disengagement portion 514 is directed to the engagement position of the first rotating disc 511a and the transmission gear 430, so that the driving force transmission member 511 stops rotating. The second rotating disc 511b is coaxially arranged on the driving force transmission member 511 and can be achieved by an integral structure or by keying, welding or other means. Each driving tooth portion 512 is circumferentially arranged on the second rotating disc 511b, and the adjacent driving tooth portions 512 have an intermittent interval. In the intermittent interval, the second rotating disc 511b does not act on the connecting tooth portion 524, so that the slider 522 can be reset to the non-sensing area by the first elastic member 530, thereby leaving the detection component area and canceling the triggering of the detection signal to form an intermittent interval between the detection signals. Thus, the selective transmission of the driving force on the driving force transmission member 511 is achieved to form corresponding detection information, and the disengagement portion 514 on the first rotating disc 511a is used to automatically disengage the engagement between the driving force transmission member 511 and the transmission gear 430 after the transmission of the detection information, so that the driving force transmission member 511 stops receiving the driving force and is in a stopped state. For example, in the embodiment shown in FIG. 6, the disengagement portion 514 is located between the two ends of the transmission tooth portion 513, and when the initial engagement position between the first rotating disc 511a and the transmission gear 430 is the starting position of the transmission tooth portion 513, the driving force transmission member 511 moves nearly one circle under the action of the transmission tooth portion 513 to the disengagement position of the first rotating disc 511a. Correspondingly, each driving tooth portion 512 on the second rotating disc 511b engages with the connecting tooth portion 524 to form a detection signal. Figure 7

[0056] ​In addition, the driving force transmission member 511 further has at least one time stopping portion 515 circumferentially arranged thereon, the time stopping portion 515 is located at a position downstream of the driving tooth portion 512 in the rotation direction of the driving force transmission member 511 and is in close proximity to the driving tooth portion 512, so that the time stopping portion 515 acts on the connecting tooth portion 524 after the corresponding driving tooth portion 512 is disengaged from the connecting tooth portion 524, wherein the distance between the time stopping portion 515 and the rotation axis of the driving force transmission member 511 is not less than the distance between the meshing position of the connecting tooth portion 524 on the driving tooth portion 512 and the rotation axis, so that after the driving tooth portion 512 is disengaged from the connecting tooth portion 524, the time stopping portion 515 continues to abut against one of the teeth (usually the last tooth, i.e., the second tooth) of the connecting tooth portion 524, preventing the slider 522 from being reset under the action of the first elastic member 530, so as to generate a short stay at the sensing position, and the length of the stay is related to the circumferential length of the time stopping portion 515, so as to be able to realize the length control of the detection signal. Specifically, when the position of the slider 522 driven by each driving tooth portion 512 is certain, the length of the detection signal brought by the driving tooth portion 512 should be consistent, thereby increasing the time stopping portion 515, and through the structure of the time stopping portion 515 with different lengths, the lengths of the corresponding detection signals are different, for example, when two driving tooth portions 512 are arranged on the second rotation disc 511b, the length of the detection signal on the first driving tooth portion 512 needs to be shorter than the length of the detection signal on the second driving tooth portion 512, and thus the length of the time stopping portion 515 on the first driving tooth portion 512 is smaller than the length of the time stopping portion 515 on the second driving tooth portion 512, so as to generate signals with different detection lengths, so as to transmit corresponding detection information. Based on this, the embodiment can utilize the number of detection signals and the length control of the detection length to control the transmission of detection information, realize the diversified demand of information transmission, and ensure the detection accuracy at the same position while the driving tooth portion 512 drives the slider 522 to the same position and the time stopping portion 515 realizes the stay time of the movable plate 523, and at the same time, the embodiment can adapt to the diversified detection requirements without increasing the activity space of the slider 522.

[0057] In specific embodiments, for example Figure 12The slider 522 comprises a first part 523c and a second part 523d arranged along the axial direction of the second rotating disc 511b, the first part 523c is closer to the first side than the second part 523d, the connecting tooth part 524 is arranged on the first part, and the movable plate 523 is movably arranged on the second part 523d. This structure reasonably designs the space between the connecting tooth part 524 and the movable plate 523 in the case of reserving the assembly space of the first elastic member 530 and the second elastic member 540, so that part of the connecting tooth part 524 is located on the inner side of the movable plate 523, so as to be hidden in the storage space for protection. The bottom of the base body 521 is provided with a sliding groove 521c, and the bottom of the slider 522 is provided with a sliding protrusion 5233 arranged in the sliding groove 521c, so that the slider 522 can move along the first track relative to the sliding groove 521c.

[0058] Referring to Figure 6 and Figure 7 The trigger component 500 further comprises a third elastic member 550, and the rotating member 510 further comprises a position holding part 525, wherein the position holding part 525 is located between the first rotating disc 511a and the second rotating disc 511b, rotates with the driving force transmission member 511, and has a disengaging notch 525a which is open in the radial direction away from the rotation axis of the driving force transmission member 511. The disengaging notch 525a in the embodiment is formed by two circumferentially arranged fixed pieces 525b. The third elastic member 550 is connected to the base body 521, the cover component 300 or the box body 100 (in the embodiment, the connection position is located on the cover component 300) and has a pressing part 551 which presses against the circumferential side wall of the position holding part 525. When the disengaging part 514 is towards the meshing position of the first rotating disc 511a and the transmission gear 430, the third elastic member 550 presses against the disengaging notch 525a, so as to keep the driving force transmission member 511 in the disengaging position when the driving force transmission member 511 is disengaged from the transmission gear 430.

[0059] In the embodiment of the present application, when the second gear 420 receives the driving force from the device body, the first gear 410 on the transmission component 400 drives the first roller 200 to rotate, the transmission gear 430 engages with the transmission tooth part 513 at the starting position to drive the first rotating disc 511a to rotate, and then drives the driving force transmission member 511 to operate as a whole. During the operation, the driving tooth part 512 engages with the connecting tooth part 524 to move the sliding block 522 from the non-sensing area to the sensing area, so as to trigger the detection signal of the detection component. When the driving tooth part 512 is separated from the connecting tooth part 524, the time stop part 515 makes the sliding block 522 stay at the sensing position for a specified time, until the time stop part 515 is separated from the connecting tooth part 524, the sliding block 522 is moved from the non-sensing area to the sensing area under the action of the first elastic member 530, the detection signal on the detection component disappears, and thus when the last driving tooth part 512 is separated from the connecting tooth part 524 and the first rotating disc 511a is separated from the transmission gear 430, the detection process stops. As for the reset in the embodiment of the present application, it is only needed to manually continue to rotate the driving force transmission member 511 along the original rotating direction to make the driving force transmission member 511 engage with the transmission gear, so as to perform the next detection process, which is very simple and efficient.

[0060] Finally, it should be noted that the above description is only the best embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and simple replacements to the technical scheme of the present application without departing from the scope of the technical scheme of the present application, which belongs to the protection scope of the technical scheme of the present application.
