According to the blocking structure, the blocking piece of the blocking structure is rotatably arranged on the first conveying mechanism, and the pushing piece of the blocking structure is arranged on the second conveying mechanism and can synchronously move with the second conveying mechanism; therefore, when the second conveying mechanism moves to the second working position and transfers the consumable box with the first conveying mechanism, the pushing piece synchronously drives the blocking piece located at the blocking position to the releasing position, and then the pushing piece is driven to drive the blocking piece to move to the releasing position ingeniously through movement of the second conveying mechanism. Consumable boxes can be transferred between the first conveying mechanism and the second conveying mechanism, and a special driving device used for driving the blocking piece to move is avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a blocking structure, a conveying module and a sample analyzer. Background Art

[0002] Biochemical analyzers, immunoassay analyzers and cell analyzers are all sample analyzers, which are instruments used to perform quantitative and qualitative detection and analysis of samples.

[0003] Before or during sample analysis, the sample analyzer needs to automatically transport consumables (such as pipette heads) to a designated location for use. Since the transport of consumable boxes containing pipette heads is continuous, a blocking structure is required to block and position the consumable boxes to ensure that each consumable box reaches the designated location smoothly during the transport process. When the currently blocked and positioned consumable box needs to be transported, the blocking structure is controlled to stop blocking and positioning the consumable box, so that the consumable box can continue to be transported forward.

[0004] In the prior art, the blocking structure often needs to be provided with a dedicated driving device to realize the switching between the blocking position and the releasing position, so as to realize the blocking limit or release of the consumable box. Utility Model Content

[0005] The main purpose of the present application is to provide a blocking structure, a conveying module and a sample analyzer to solve the problem in the prior art that a dedicated driving device is required to drive the blocking structure to switch between a blocking position and a release position.

[0006] In one aspect, the present application provides a blocking structure, comprising:

[0007] a blocking member, the blocking member being rotatably disposed on a side of the first conveying mechanism and being used to block the consumable box, the first conveying mechanism being used to convey the consumable box;

[0008] A pushing member, wherein the pushing member is arranged on the side of the second conveying mechanism and can move synchronously with the second conveying mechanism, the second conveying mechanism has a first working position and a second working position, when the second conveying mechanism is in the first working position, the blocking member is in the blocking position and blocks the movement of the consumable box on the first conveying mechanism, when the second conveying mechanism is in the second working position, the pushing member pushes the blocking member to move to the release position, and the consumable box can be transferred between the first conveying mechanism and the second conveying mechanism.

[0009] Further, during the process that the second conveying mechanism moves from the first working position to the second working position, the pushing member gradually drives the blocking member to move from the blocking position to the releasing position.

[0010] Furthermore, the first conveying mechanism conveys the consumable box in a horizontal direction;

[0011] The second conveying mechanism conveys the consumable box in a vertical direction and can drive the pushing member to move in the vertical direction to pass over the blocking member, wherein when the second conveying mechanism moves vertically downward or upward to the second working position, the pushing member can drive the blocking member to switch from the blocking position to the releasing position, and after the second conveying mechanism leaves the second working position vertically upward or downward, the blocking member will switch from the releasing position to the blocking position.

[0012] Further, the pushing member includes a first inclined surface;

[0013] The blocking member includes a rotating part, a blocking part and a following part. The blocking member is connected to the first conveying mechanism through the rotating part and can rotate along the rotation axis relative to the first conveying mechanism. The movement of the second conveying mechanism drives the pushing member to move so that the first inclined surface drives the following part to rotate along the rotation axis. The rotation of the following part drives the blocking part to move so that the blocking member switches from the blocking position to the release position.

[0014] Furthermore, the follower part is provided with a roller, and the movement of the second conveying mechanism drives the pushing member to move so that when the first inclined surface drives the follower part to rotate along the rotation axis, the roller can contact the first inclined surface.

[0015] Furthermore, the pusher further includes a second inclined surface and a plane, the second inclined surface has an opposite slope to the first inclined surface, and the plane is connected between the first inclined surface and the second inclined surface so that the cross section of the pusher is an isosceles trapezoid;

[0016] When the pusher moves so that the follower reaches the plane, the blocking member is in the release position, and the consumable box can be transferred between the first conveying mechanism and the second conveying mechanism;

[0017] After the pushing member moves to make the follower portion leave the pushing member from the plane along the first inclined surface or the second inclined surface, the blocking member switches to the blocking position.

[0018] Furthermore, the first conveying mechanism includes a mounting frame, a mounting seat is provided on the mounting frame, a bearing is provided on the mounting seat, the bearing is connected to a rotating shaft that can rotate along the rotation axis, and one end of the rotating shaft extends out of the mounting seat and is connected to the rotating part.

[0019] Furthermore, it also includes a reset member, which is used to drive the blocking member to remain in the blocking position.

[0020] Furthermore, the reset element is an elastic reset element.

[0021] On the other hand, the present application also provides a conveying module, which includes the blocking structure described in any one of the above items, and also includes a first conveying mechanism and a second conveying mechanism. The blocking member of the blocking structure can be rotatably provided on the first conveying mechanism, and the pushing member of the blocking structure can move synchronously with the second conveying mechanism to drive the blocking member to switch from a blocking position to a release position.

[0022] Furthermore, the second conveying mechanism includes a bracket, which is used to carry the consumable box, and the bracket includes a bearing portion and a side stop structure. The side stop structure is arranged on the bearing portion and encloses an opening on the bearing portion. When the second conveying mechanism is located in the second working position, the opening is connected to the first conveying mechanism.

[0023] Furthermore, the first conveying mechanism conveys the consumable box in a horizontal direction, and the second conveying mechanism conveys the consumable box in a vertical direction.

[0024] Further, the first conveying mechanism is used to convey the consumable box to the second conveying mechanism;

[0025] The conveying module further includes a third conveying mechanism for recovering the consumable box from the second conveying mechanism, the third conveying mechanism is located below the first conveying mechanism, and another blocking member is provided on the third conveying mechanism;

[0026] The second conveying mechanism also has a third working position. When the second conveying mechanism is in the third working position, the pushing member pushes the blocking member corresponding to the third conveying mechanism to move to a release position, and the consumable box on the second conveying mechanism can be transferred to the third conveying mechanism.

[0027] On the other hand, the present application further provides a sample analyzer, comprising any one of the above-mentioned conveying modules.

[0028] In the blocking structure of the present application, the blocking member of the blocking structure is rotatably arranged on the side of the first conveying mechanism, and the pushing member of the blocking structure is arranged on the side of the second conveying mechanism and moves synchronously with the second conveying mechanism. Therefore, when the second conveying mechanism moves to the second working position and transfers the consumable box with the first conveying mechanism, the pushing member synchronously drives the blocking member in the blocking position to the release position, and then cleverly utilizes the movement of the second conveying mechanism to drive the pushing member to drive the blocking member to move to the release position, so that the consumable box can be transferred between the first conveying mechanism and the second conveying mechanism, and avoids the need to provide a dedicated driving device for driving the blocking member to move. In addition, by arranging the blocking member on the side of the first conveying mechanism, it can be avoided that when the consumable box moves from the first conveying mechanism to the second conveying mechanism, the blocking member in the blocking position is pushed and switched to the release position, resulting in the failure of the blocking member to block the consumable box.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0045] See also Figure 1-10 As shown, the present application provides a blocking structure, including a blocking member 10 and a pushing member 20, wherein the pushing member 20 is used to drive the blocking member 10 to switch from a blocking position to a releasing position.

[0046] Furthermore, the blocking member 10 is rotatably disposed on the first conveying mechanism 200, and the first conveying mechanism 200 is used to convey the consumable box 300. When the blocking member 10 is in the blocking position, it can be used to block the consumable box 300 on the first conveying mechanism 200, thereby preventing the consumable box 300 on the first conveying mechanism 200 from continuing to be transported forward.

[0047] The pusher 20 is disposed on the second conveying mechanism 400 and can move synchronously with the second conveying mechanism 400. The pusher 20 can drive the blocking member 10 in the blocking position to the releasing position as the second conveying mechanism 400 moves. At this time, the consumable box 300 on the first conveying mechanism 200 can move to the second conveying mechanism 400; or, the consumable box 300 on the second conveying mechanism 400 can move to the first conveying mechanism 200.

[0048] Furthermore, the second conveying mechanism 400 has a first working position and a second working position. When the second conveying mechanism 400 is in the first working position, the blocking member 10 is in the blocking position and blocks the movement of the consumable box 300 on the first conveying mechanism 200, and at this time, the pushing member 20 is separated from the blocking member 10.

[0049] When the second conveying mechanism 400 is in the second working position, the pushing member 20 pushes the blocking member 10 to move from the blocking position to the releasing position, thereby facilitating the transfer of the consumable box 300 between the first conveying mechanism 200 and the second conveying mechanism 400 .

[0050] Furthermore, the blocking member 10 is arranged on the side of the first conveying mechanism 200, and the pushing member 20 is arranged on the side of the second conveying mechanism 400 corresponding to the blocking member 10. Therefore, by setting the blocking member 20 on the side of the first conveying mechanism 200, it can be avoided that when the consumable box 300 moves toward the second conveying mechanism 400 on the first conveying mechanism 200, the blocking member 10 located at the blocking position is pushed and switched to the release position, resulting in the failure of the blocking member 10 to block the consumable box 300, causing the consumable box 300 on the first conveying mechanism 200 to fall off.

[0051] Further, the first conveying mechanism 200 is used to convey the consumable box 300 along a first direction, and the second conveying mechanism 400 is used to convey the consumable box 300 along a second direction. The first direction and the second direction may be the same direction or different directions. For example, the first direction and the second direction are both horizontal directions; or, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0052] Furthermore, during the process of the second conveying mechanism 400 moving from the first working position to the second working position, the second conveying mechanism 400 drives the pushing member 20 to move so that the pushing member 20 gradually approaches the blocking member 10, and after the pushing member 20 begins to contact the blocking member 10, the blocking member 10 is gradually driven to move from the blocking position to the release position.

[0053] Furthermore, in one embodiment, the first conveying mechanism 200 conveys the consumable box 300 in a horizontal direction, and the second conveying mechanism 400 conveys the consumable box 300 in a vertical direction.

[0054] The pushing member 20 moves along the vertical direction along with the second conveying mechanism 400 so that the pushing member 20 can pass over the blocking member 10 .

[0055] When the second conveying mechanism 400 moves vertically downward to the second working position, the pushing member 20 can drive the blocking member 10 to switch from the blocking position to the releasing position. When the second conveying mechanism 400 continues to move downward and crosses the second working position in the direction away from the first working position, the pushing member 20 moves synchronously with the second conveying mechanism 400 and crosses the blocking member 10. At this time, the blocking member 10 will switch from the releasing position back to the blocking position.

[0056] When the second conveying mechanism 400 moves vertically upward to the second working position, the pushing member 20 can drive the blocking member 10 to switch from the blocking position to the releasing position. When the second conveying mechanism 400 continues to move upward and crosses the second working position toward the first working position, the pushing member 20 moves synchronously with the second conveying mechanism 400 and crosses the blocking member 10. At this time, the blocking member 10 will switch from the releasing position back to the blocking position.

[0057] For further information, please refer to Figure 3 As shown, in one embodiment, the pushing member 20 includes a first inclined surface 21, and the pushing member 20 moves along with the second conveying mechanism 400 so that the first inclined surface 21 contacts the blocking member 10, and gradually drives the blocking member 10 to rotate relative to the first conveying mechanism 200 under the continuous movement of the second conveying mechanism 400 until the blocking member 10 moves from the blocking position to the release position.

[0058] For further information, please refer to Figure 6-9 As shown, the blocking member 10 includes a rotating portion 11, a blocking portion 12 and a follower portion 13. The blocking member 10 is connected to the first conveying mechanism 200 through the rotating portion 11 and can rotate relative to the first conveying mechanism 200 along the rotation axis 30. The movement of the second conveying mechanism 400 drives the pushing member 20 to move so that the first inclined surface 21 drives the follower portion 13 to rotate along the rotation axis 30. The rotation of the follower portion 13 drives the blocking portion 12 to move so that the blocking member 10 switches from the blocking position to the releasing position.

[0059] When the blocking member 10 is in the blocking position, the blocking portion 12 blocks the conveying path of the first conveying mechanism 200 . At this time, the consumable box 300 on the first conveying mechanism 200 cannot continue to move forward with the first conveying mechanism 200 due to the blocking of the blocking portion 12 .

[0060] When the blocking member 10 is in the release position, the blocking portion 12 no longer blocks the conveying path of the first conveying mechanism 200 . At this time, the consumable box 300 located on the first mechanism can continue to be conveyed forward along with the first conveying mechanism 200 and transferred to the second conveying mechanism 400 .

[0061] Furthermore, the first conveying mechanism 200 includes a mounting frame 210 and a first conveying unit 220. The first conveying unit 220 is disposed on the mounting frame 210 and can convey the consumable box 300 along the first direction.

[0062] The blocking structure further includes a mounting seat 40, a bearing 50 and a rotating shaft 60. The mounting seat 40 is disposed on the mounting frame 210, the outer ring of the bearing 50 is fixedly connected to the mounting seat 40, the inner ring of the bearing 50 is connected to the rotating shaft 60, and the rotating shaft 60 can rotate along the rotation axis 30, and one end of the rotating shaft 60 extends out of the mounting seat 40 and is connected to the rotating part 11.

[0063] By providing the bearing 50 and the rotating shaft 60 to connect the blocking member 10 to the mounting seat 40 , the blocking member 10 can be more stable and smooth when rotating about the rotating axis 30 .

[0064] In some embodiments, the mounting seat 40 is further provided with a first limit pin 70 and a second limit pin 80, wherein the first limit pin 70 is used to limit the blocking member 10 to pass the blocking position, and the second limit pin 80 is used to limit the blocking member 10 to pass the release position.

[0065] Furthermore, in one embodiment, a relief area 211 is provided on the mounting frame 210 corresponding to the blocking portion 12. The relief area 211 may be a relief hole or a relief gap.

[0066] When the blocking member 10 is in the blocking position, the blocking portion 12 at least partially passes through the avoidance area 211 and blocks the conveying path of the first conveying unit.

[0067] Furthermore, a detection unit 500 is provided on the mounting frame 210 , and the detection unit 500 is used to detect whether the blocking member 10 is in the blocking position.

[0068] In one implementation, the detection unit 500 is a light detector, and when the detection light emitted by the light detector is blocked and reflected by the blocking member 10, the blocking member 10 is in the blocking position.

[0069] In another embodiment, the detection unit 500 is a slot-type optical coupler, and the blocking member 10 has a sensing portion 16 corresponding to the slot-type optical coupler. When the sensing portion 16 is located in the slot-type optical coupler, the blocking member 10 is in the blocking position.

[0070] Furthermore, the follower part 13 is provided with a roller 14 , and the second conveying mechanism 400 moves to drive the pushing member 20 to move so that when the first inclined surface 21 drives the follower part 13 to rotate along the rotation axis 30 , the roller 14 can contact the first inclined surface 21 .

[0071] The roller 14 can reduce the friction force when the follower 13 contacts the first inclined surface 21, thereby improving the smoothness of the rotation of the blocking member 10. Preferably, the roller 14 is a bearing.

[0072] Furthermore, the pusher 20 further includes a second inclined surface 22 and a plane 23. The second inclined surface 22 has an opposite slope to the first inclined surface 21, and the plane 23 is connected between the first inclined surface 21 and the second inclined surface 22 so that the cross section of the pusher 20 is an isosceles trapezoid.

[0073] When the second conveying mechanism 400 moves from the first working position to the second working position, the pusher 20 moves so that the follower 13 reaches the plane 23. At this time, the blocking member 10 is in the release position, and the consumable box 300 can be transferred between the first conveying mechanism 200 and the second conveying mechanism 400.

[0074] When the follower 13 contacts the first inclined surface 21 or the second inclined surface 22 and moves toward the plane 23 , the blocking member 10 rotates along the rotation axis 30 so that the blocking member 10 moves from the blocking position to the releasing position.

[0075] Further, when the second conveying mechanism 400 moves to drive the pushing member 20 away from the blocking member 10, the pushing member 20 moves so that the follower portion 13 leaves the pushing member 20 from the plane 23 along the first inclined surface 21 or the second inclined surface 22. At this time, the blocking member 10 switches to the blocking position.

[0076] Furthermore, a reset member 90 is included, and the reset member 90 is used to drive the blocking member 10 to remain in the blocking position.

[0077] In the first embodiment, the reset member 90 is an elastic reset member. The elastic reset member is used to drive the blocking member 10 to remain in the blocking position. The push member 20 pushes the blocking member 10 to rotate along the rotation axis 30 so that the blocking member 10 switches from the blocking position to the release position, and provides a force driving the blocking member 10 to switch back to the blocking position when the blocking member 10 switches to the release position.

[0078] Furthermore, the blocking member 10 is provided with a first connecting portion 15 , the mounting seat 40 is provided with a second connecting portion 41 , the first end of the elastic return member is connected to the first connecting portion 15 , and the second end of the tension spring is connected to the second connecting portion 41 .

[0079] The elastic reset member is connected between the first connection portion 15 and the second connection portion 41. The elastic reset member may be in a stressed state only when the blocking member 10 is in the release position, that is, when the blocking member 10 is in the blocking position, the elastic reset member is not in a stressed state.

[0080] Therefore, when the blocking member 10 switches from the blocking position to the releasing position, the elastic reset member gradually switches from a non-stressed state to a stressed state. That is, before the pusher 20 contacts or starts to contact the blocking member 10, the elastic reset member is in a non-stressed state until the pusher 20 pushes the blocking member 10 to rotate a certain angle, and then the elastic reset member starts to be in a stressed state, and when the blocking member 10 switches to the releasing position, the force applied to the elastic reset member reaches the maximum.

[0081] Alternatively, the elastic reset member may also be connected between the first connection portion 15 and the second connection portion 41 in a state of being always under stress. That is, when the blocking member 10 is in the blocking position, the elastic reset member is in a first state of being under stress, and when the blocking member 10 is in the releasing position, the elastic reset member is in a second state of being under stress. The force applied to the elastic reset member in the second state of being under stress is greater than the force applied to the elastic reset member in the first state.

[0082] In one embodiment, the elastic return member is a tension spring connected between the first connection portion 15 and the second connection portion 41 .

[0083] In another embodiment, the elastic member is an elastic cord connected between the first connecting portion 15 and the second connecting portion 41 .

[0084] In other embodiments, the elastic member is a torsion spring, which is sleeved on the rotating shaft 60 , and a first torsion arm of the torsion spring abuts against the mounting seat 40 or the mounting bracket 210 , and a second torsion arm of the torsion spring abuts against the blocking member 10 .

[0085] In a second embodiment, the resetting member 90 includes a first magnetic member and a second magnetic member. The first magnetic member is disposed on the blocking member 10, and the second magnetic member is disposed on the first conveying mechanism 200 and can attract the first magnetic member.

[0086] When the blocking member 10 is in the release position, there is still a mutual attraction force between the first magnetic member and the second magnetic member to drive the blocking member 10 to rotate so that the first magnetic member and the second magnetic member are close to or attracted to each other.

[0087] In one embodiment, when the blocking member 10 is in the blocking position, the first magnetic member and the second magnetic member are attracted together.

[0088] In another embodiment, when the blocking member 10 is in the blocking position, the first magnetic member and the second magnetic member are spaced a certain distance apart, and the first magnetic member and the second magnetic member have a mutual attraction force.

[0089] In the third embodiment, the reset member 90 is a counterweight block, which is disposed on the blocking member 10 and can drive the blocking member 10 to remain in the blocking position. That is, in this embodiment, the blocking member 10 is driven to remain in the blocking position by the gravity of the counterweight block.

[0090] In one embodiment, the counterweight block is detachably connected to the blocking member 10 .

[0091] In another embodiment, the counterweight block and the blocking member 10 are an integrated structure, that is, the blocking member 10 can be maintained at the blocking position by its own gravity.

[0092] Please refer to Figure 1-5 As shown, on the other hand, the present application further provides a conveying module, which includes the blocking structure described in any one of the above embodiments. Therefore, the conveying module has the beneficial effects described in any one of the above embodiments, which will not be repeated here.

[0093] Furthermore, the conveying module further comprises the above-mentioned first conveying mechanism 200 and second conveying mechanism 400. The blocking member 10 of the blocking structure is rotatably disposed on the first conveying mechanism 200, and the pushing member 20 of the blocking structure can move synchronously with the second conveying mechanism 400 to drive the blocking member 10 to switch from the blocking position to the release position.

[0094] Furthermore, the second conveying mechanism 400 includes a bracket 430, and the bracket 430 is used to carry the consumable box 300. By providing the bracket 430, the consumable box 300 can be carried more stably, so that the consumable box 300 is transferred from the first conveying mechanism 200 to the second conveying mechanism 400.

[0095] Furthermore, the bracket 430 includes a bearing portion 431 and a side stop structure 432, the side stop structure 432 is arranged on the bearing portion 431 and encloses an opening 433 on the bearing portion 431, and when the second conveying mechanism 400 is located at the second working position, the opening 433 is connected to the first conveying mechanism 200.

[0096] By setting the side stop structure 432, the consumable box 300 on the bearing portion 431 can be effectively limited to prevent the consumable box 300 from falling when being transferred from the first conveying mechanism 200 to the second conveying mechanism 400, and the consumable box 300 can be limited so that the consumable box 300 can be stably conveyed by the second conveying mechanism 400.

[0097] Furthermore, the side baffle structure 432 includes two first baffles 4321 arranged on opposite sides along the conveying direction of the first conveying mechanism 200, and a baffle rod 4322 connected to the same side of the two first baffles 4321 and located at one end of the two first baffles 4321 away from the first conveying mechanism 200.

[0098] In one embodiment, the first conveying mechanism 200 conveys the consumable box 300 in a horizontal direction, and the second conveying mechanism 400 conveys the consumable box 300 in a vertical direction. The second conveying mechanism 400 includes a bracket 410 and a second conveying unit 420, which is disposed on the bracket 410 and can convey the consumable box 300 in a vertical direction.

[0099] When the second conveying mechanism 400 is in the first working position, the second conveying unit 420 is located above the first conveying unit 220. At this time, the consumables (such as T IP heads) in the consumable box 300 carried by the second conveying unit 420 can be loaded.

[0100] When the consumables in the consumable box 300 located at the first working position are fully loaded or do not need to be loaded further, and another consumable box 300 needs to be replaced, the current consumable box 300 will be discarded, and after being discarded, the second conveying mechanism 400 will move to the second working position to transfer another consumable box 300 carrying consumables from the first conveying mechanism 200.

[0101] Furthermore, in one embodiment, the first conveying mechanism 200 is used to convey the consumable box 300 to the second conveying mechanism 400. The conveying module further includes a third conveying mechanism 600 for recovering the consumable box 300 from the second conveying mechanism 400. The third conveying mechanism 600 is located below the first conveying mechanism 200.

[0102] Furthermore, another blocking member 10 is provided on the third conveying mechanism 600. When the third conveying mechanism 600 conveys the consumable box 300 carried by it in the reverse direction, that is, when the consumable box 300 is conveyed toward the second conveying mechanism 400, the blocking member 10 is used to block the consumable box 300 carried by the third conveying mechanism 600.

[0103] Furthermore, in the first case, when the conveying module is initialized, the third conveying mechanism 600 first conveys the consumable boxes 300 it carries in reverse so that all the consumable boxes 300 it carries are close to each other, and the consumable box closest to the second conveying mechanism 400 is blocked by the blocking member 10. Only then does the conveying module complete the initialization, and then the third conveying mechanism 600 recycles the consumable boxes 300 it carries, and the conveying module simultaneously starts to count the recycled consumable boxes 300.

[0104] In the second case, when the number of the consumable boxes 300 recycled in the recycling box reaches a preset number, the recycling box will be pulled out of the transmission module to facilitate the transfer of the consumable boxes 300 in the recycling box. When the recycling box is pulled out, the third conveying mechanism 600 will reversely convey the consumable boxes 300 it carries and block them through the blocking member 10 to prevent the consumable boxes on the third conveying mechanism 600 from falling.

[0105] Furthermore, the second conveying mechanism 400 also has a third working position. When the second conveying mechanism 400 is in the third working position, the pusher 20 pushes the blocking member 10 corresponding to the third conveying mechanism 600 to move to a release position, at which time the consumables box 300 on the second conveying mechanism 400 can be transferred to the third conveying mechanism 600, and transferred and discarded by the third conveying mechanism 600.

[0106] In this embodiment, the consumable box 300 carrying consumables is conveyed to the second conveying mechanism 400 located at the second working position by the first conveying mechanism 200, and the consumable box 300 is driven to move to the first working position by the second conveying mechanism 400 so that the consumables carried in the consumable box 300 can be loaded, and the consumable box 300 is conveyed to the third working position by the second conveying mechanism 400 after loading and transferred to the third conveying mechanism 600, and transferred and discarded by the third conveying mechanism 600, thereby realizing the automated operation of the conveying and supply of consumables and the recycling of the consumable box 300.

[0107] In another aspect, the present application further provides a sample analyzer, the sample analyzer comprising the conveying module described in any of the above embodiments. Therefore, the sample analyzer also comprises all the beneficial effects of the above conveying module, which will not be described in detail here.

[0108] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0109] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0110] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
