[0055] Thirdly, this application discloses a sample analyzer, which includes the reagent addition device described in any of the second aspects above.

[0056] Fourthly, this application discloses a compartment door opening and closing mechanism, applied in a sample analyzer having a compartment body, the compartment body including a compartment cover with an opening, and the compartment door opening and closing mechanism comprising:

[0057] The door can move forward along a first preset path to a first position to close the opening, and the door can move backward along the first preset path to a second position to open the opening;

[0058] A drive assembly includes a movable component that can move along a second preset path and a drive component that drives the movable component to move. The movable component and the compartment door are relatively movable within a preset distance along a direction parallel to the first preset path.

[0059] Optionally, when the driving member drives the moving member to move the preset distance in the forward direction along the second preset path, the compartment door remains stationary relative to the opening. When the driving member continues to drive the moving member to move in the forward direction along the second preset path, the moving member can drive the compartment door to move in the forward direction along the first preset path to the first position. When the driving member drives the moving member to move the preset distance in the reverse direction along the second preset path, the compartment door remains stationary relative to the opening. When the driving member continues to drive the moving member to move in the reverse direction along the second preset path, the moving member can drive the compartment door to move in the reverse direction along the first preset path to the second position.

[0060] Fifthly, this application discloses a compartment door opening and closing mechanism, applied in a sample analyzer having a compartment body, the compartment body including a compartment cover with an opening, and the compartment door opening and closing mechanism comprising:

[0061] The door can move forward along a first preset path to a first position to close the opening, and the door can move backward along the first preset path to a second position to open the opening;

[0062] A first blocking part is disposed on the first preset path to limit the forward movement of the compartment door along the first preset path;

[0063] A drive assembly, comprising a movable component capable of reciprocating along a second preset path and a drive component for driving the movable component to move, wherein the movable component is detachably connected to the compartment door;

[0064] The driving member can drive the moving member to move forward along the second preset path to a third position corresponding to the first blocking part to connect with the compartment door, and the driving member can drive the moving member to move backward along the second preset path to leave the third position to separate from the compartment door.

[0065] Compared with the prior art, the beneficial effects of this application are as follows:

[0066] By causing the movable component to move forward or backward along the second preset path, the door can be moved forward along the first preset path to a first position to close the opening, or the door can be moved backward along the first preset path to a second position to open the opening. In other words, the purpose of closing or opening the opening can be achieved. Therefore, when the door opening / closing mechanism is applied to a sample analyzer with a compartment and the opening is closed, the thermal insulation performance of the compartment can be improved.

[0067] Furthermore, by enabling a detachable connection between the moving part and the door, when the moving part and the door are connected, their movements are synchronized, allowing the door to be opened or closed via the movement of the moving part. When the moving part and the door are disconnected, their movements are independent.

[0068] When the movement of the moving component and the door are independent, their movements will not affect each other. This means that, on the one hand, the moving component's continued forward movement along the second preset path will not cause the door to continue moving along the first preset path, thus preventing the door from exceeding its opening along the first preset path. On the other hand, the moving component can continue moving independently along the second preset path without affecting the door, resulting in greater independence between their movements. This allows the moving component to perform functions independently without affecting the door, enabling it to perform functions beyond simply moving the door. For example, a transfer tray can be mounted on the moving component. When a reagent bottle to be replaced is placed on the transfer tray, the moving component can continue moving independently along the second preset path to transport the bottle without affecting the door.

[0084] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0085] Example 1

[0086] Figure 1 This is a schematic diagram of the structure of a warehouse door opening and closing mechanism provided in an embodiment of this application when the opening is in the open state. Figure 2 yes Figure 1 A schematic diagram of the structure of the warehouse door opening and closing mechanism when the opening is closed.

[0087] See Figure 1 and Figure 2 The door opening and closing mechanism 100 can be applied to a sample analyzer 300 having a compartment body 200. The compartment body 200 includes a compartment cover 201 with an opening 2011. The door opening and closing mechanism 100 includes: a compartment door 1, a first blocking part 2, and a driving assembly 3. The compartment door 1 can move along a first preset path W1 in the forward direction (…). Figure 1 The positive direction of the X-axis moves to the first position. Figure 2 The location of the central storage door) is used to close the opening 2011. The storage door 1 can move in the opposite direction of the first preset path W1 ( Figure 2 The negative X-axis direction moves to the second position. Figure 1 The location of the central compartment door is used to open the opening 2011. The first blocking part 2 is provided on the first preset path W1. The drive assembly 3 includes a drive member 31 and a moving member 32 connected to the drive member 31, and the moving member 32 is detachably connected to the compartment door 1.

[0088] The driving component 31 can drive the moving component 32 along the positive direction of the second preset path W2. Figure 2 The positive direction of the X-axis moves to the third position. Figure 2 The location of the moving part), so as to drive the door 1 along the positive direction of the first preset path W1 ( Figure 2The positive direction of the X-axis moves to the first position. Figure 2 (At the location of the middle compartment door), the first blocking part 2 can continue to drive the compartment door 1 along the first preset path W1 in the positive direction via the movable part 32. Figure 2 When the door 1 moves in the positive direction of the X-axis, it separates from the moving part 32. The driving part 31 can drive the moving part 32 in the opposite direction of the second preset path W2. Figure 2 The negative X-axis direction moves to the third position. Figure 2 The position of the moving part), so that the moving part 32 can be detachably connected to the door 1, and the driving part 31 can continue to drive the moving part 32 in the opposite direction along the second preset path W2 ( Figure 2 The negative X-axis direction moves to drive the door 1 in the opposite direction along the first preset path W1. Figure 2 The negative X-axis direction moves to the second position. Figure 1 (The location of the central warehouse gate).

[0089] In this embodiment, since the driving member 31 is connected to the moving member 32, and the moving member 32 is detachably connected to the door 1, when the moving member 32 and the door 1 are in a connected state, when the driving member 31 drives the moving member 32 along the positive direction of the second preset path W2 ( Figure 2 The positive direction of the X-axis moves to the third position. Figure 2 When the moving part is in its current position, it can simultaneously drive the door 1 along the positive direction of the first preset path W1. Figure 2 The positive direction of the X-axis moves to the first position. Figure 2 The location of the middle compartment door), causing the compartment door 1 to close the opening 2011. Next, since the first blocking part 2 is positioned on the first preset path W1, when the driving member 31 continues to drive the moving member 32 along the positive direction of the second preset path W2 ( Figure 2 When the X-axis moves in the positive direction to continue driving the door 1 to move in the positive direction along the first preset path W1, the first blocking part 2 can prevent the door 1 from continuing to follow the moving part 32, so that the moving part 32 is separated from the door 1 and the connection between the moving part 32 and the door 1 is disconnected. This allows the opening 2011 to remain closed while ensuring that the moving part 32 can continue to move in the positive direction along the second preset path W2 on its own.

[0090] When the driving component 31 drives the moving component 32 in the opposite direction of the second preset path W2 ( Figure 2 The negative X-axis direction moves to the third position. Figure 2When the moving part is in its current position, the moving part 32 can be reconnected to the door 1, allowing the moving part 32 and the door 1 to be reconnected. While the moving part 32 and the door 1 are connected, when the driving part 31 continues to drive the moving part 32 to move in the opposite direction along the second preset path W2, the moving part 32 can drive the door 1 to move in the opposite direction along the first preset path W1 to the second position. Figure 1 The location of the central warehouse door allows the opening to be opened in 2011.

[0091] As can be seen, in this embodiment of the application, by causing the movable member 32 to move forward or backward along the second preset path W2, the door 1 can be moved forward along the first preset path W1 to a first position to close the opening 2011, or the door 1 can be moved backward along the first preset path W1 to a second position to open the opening 2011. That is, the purpose of closing or opening the opening 2011 can be achieved. In this way, when the door opening and closing mechanism 100 is applied to the sample analyzer 300 with the compartment body 200 and the opening 2011 is closed, the thermal insulation performance of the compartment body can be improved.

[0092] Furthermore, by making the movable component 32 detachably connected to the door 1, when the movable component 32 and the door 1 are connected, their movements are linked, allowing the door 1 to open or close the opening 2011. When the movable component 32 and the door 1 are disconnected, their movements are independent.

[0093] When the movement of the movable component 32 and the door 1 is independent, their movements will not affect each other. In this way, on the one hand, the continued forward movement of the movable component 32 along the second preset path W2 will not cause the door 1 to continue moving forward along the first preset path W1, thus preventing the door 1 from exceeding the opening 2011 along the first preset path W1. On the other hand, the movable component 32 can continue to move independently along the second preset path W2 without affecting the door 1, resulting in a higher degree of independence between the movement of the movable component 32 and the door 1. Thus, the movable component 32 can perform certain functions independently without affecting the door 1, giving it other functions besides moving the door 1. For example, a transfer tray 403 can be installed on the movable component 32. When a reagent bottle to be replaced is placed on the transfer tray 403, the movable component 32 can continue to move independently along the second preset path W2 to transport the reagent bottle to be replaced independently without affecting the door 1.

[0094] It should be noted that the shape of the opening 2011 can be rectangular, circular or any other possible shape, and this application embodiment does not limit this.

[0095] In some embodiments, see Figure 2 The storage door 1 is slidably mounted on the storage cover 201 along a first preset path W1. By making the storage door 1 slidably mounted on the storage cover 201 along the first preset path W1, on the one hand, the movement of the storage door 1 along the first preset path W1 is more stable. On the other hand, the structure of making the storage door 1 slidably mounted on the storage cover 201 along the first preset path W1 is also relatively simple.

[0096] Of course, the slidable arrangement of the door 1 on the cover 201 along the first preset path W1 is only one possible implementation shown in this application embodiment. In another possible implementation, the door 1 can also be slidably arranged on other components of the sample analyzer 300 along the first preset path W1, as long as the door 1 can slide in both the forward and reverse directions along the first preset path W1. This application embodiment does not limit this.

[0097] In some embodiments, see Figure 2 The door 1 is slidably mounted on the cover 201 along a first preset path W1 via a slide rail assembly 11. Because the slide rail assembly 11 has a simple structure, the manufacturing cost of the door opening / closing mechanism 100 can be reduced to some extent.

[0098] Of course, the door 1 can also be slidably mounted on the cover 201 along the first preset path W1 using other structures. For example, the door 1 can also be slidably mounted on the cover 201 along the first preset path W1 using a dovetail groove structure. This application embodiment does not limit this.

[0099] When the compartment door 1 is slidably mounted on the compartment cover 201 along the first preset path W1 via the slide rail assembly 11, see Figure 2 The slide rail assembly 11 may include a first guide rail 111 and a slider 112. Figure 2 (Not shown in the image) The first guide rail 111 is disposed on the compartment cover 201 and extends along the first preset path W1. The slider 112 is slidably disposed on the first guide rail 111. The compartment door 1 is connected to the slider 112.

[0100] Since the first guide rail 111 is mounted on the cover 201 and extends along the first preset path W1, and the slider 112 is slidably mounted on the first guide rail 111, and the door 1 is connected to the slider 112, when the slider 112 slides along the first guide rail 111, it can drive the door 1 to slide along the first preset path W1, thereby achieving the purpose of the door 1 being slidably mounted on the cover 201 along the first preset path W1. On the one hand, the structural design is very simple. On the other hand, the cooperation between the first guide rail 111 and the slider 112 ensures high reliability in enabling the door 1 to be slidably mounted on the cover 201 along the first preset path W1. Therefore, it can improve the operational reliability of the entire door opening and closing mechanism 100 to a certain extent.

[0101] In some embodiments, see Figure 2 The first guide rail 111 is a linear guide rail. When the first guide rail 111 is a linear guide rail, the processing difficulty and processing cost of the door opening and closing mechanism can be reduced to a certain extent because linear guide rails are easy to process and have low cost.

[0102] It is understandable that when the first guide rail 111 is a linear guide rail, the aforementioned first preset path W1 will be a linear path.

[0103] Of course, the first guide rail 111 can also be a curved guide rail, etc. When the first guide rail 111 is a curved guide rail, the first preset path W1 will be a curved path.

[0104] In some embodiments, see Figure 2 The movable part 32 and the compartment door 1 are detachably connected via the automatic connection assembly 12. The automatic connection assembly 12 includes a first suction member 121 and a second suction member 122. The first suction member 121 is disposed on the movable part 32, and the second suction member 122 is disposed on the compartment door 1. The movement trajectory of the first suction member 121 and the movement trajectory of the second suction member 122 at least partially overlap.

[0105] Since the first suction member 121 is disposed on the moving member 32 and the second suction member 122 is disposed on the door 1, and the moving trajectory of the first suction member 121 and the moving trajectory of the second suction member 122 at least partially overlap, when the moving member 32 moves forward and backward along the second preset path W2 and the door 1 moves forward and backward along the first preset path W1, the first suction member 121 and the second suction member 122 can be attracted together, thereby achieving the purpose of detachable connection between the moving member 32 and the door 1. The method of detachable connection between the moving member 32 and the door 1 is very simple.

[0106] In one possible implementation, to achieve the attraction between the first attracting member 121 and the second attracting member 122, both the first attracting member 121 and the second attracting member 122 are magnets. When both the first attracting member 121 and the second attracting member 122 are magnets, the purpose of attracting the first attracting member 121 and the second attracting member 122 can be achieved. Since magnets are readily available and inexpensive, the manufacturing cost of the first attracting member 121 and the second attracting member 122 can be reduced.

[0107] In another possible implementation, one of the first attracting member 121 and the second attracting member 122 is a magnet and the other is a ferromagnetic component. For example, the first attracting member 121 can be a magnet and the second attracting member 122 can be a ferromagnetic component. When one of the first attracting member 121 and the second attracting member 122 is a magnet and the other is a ferromagnetic component, the first attracting member 121 and the second attracting member 122 can achieve the purpose of attraction while allowing for a wider variety of materials to be chosen for the first attracting member 121 and the second attracting member 122.

[0108] The aforementioned ferromagnetic component can be made of iron, nickel, or cobalt, as long as it can be attracted by a magnet. This application does not limit the ferromagnetic component.

[0109] In some embodiments, the automatic connection component 12 may include a first engaging component and a second engaging component. The first engaging component is disposed on the movable component 32, and the second engaging component is disposed on the door 1. The movement trajectories of the first engaging component and the second engaging component at least partially overlap. With this configuration, when the movable component 32 moves forward and backward along the second preset path W2, and the door 1 moves forward and backward along the first preset path W1, the first engaging component and the second engaging component can engage, thereby achieving a detachable connection between the movable component 32 and the door 1. The method of achieving a detachable connection between the movable component 32 and the door 1 is very simple.

[0110] Specifically, the first engaging component can be a flexible claw, and the second engaging component can be a ball, with the ball detachably engaged in the claw. When the first engaging component is a flexible claw and the second engaging component is a ball, the manufacturing cost of the flexible claw and the ball is lower, thus reducing the manufacturing cost of the automatic connection assembly 12.

[0111] In some embodiments, see Figure 2 The driving component 31 includes a bracket 311, a pulley assembly 312, and a power component 313. The pulley assembly 312 is mounted on the bracket 311, and the moving component 32 is connected to the pulley assembly 312. The power component 313 is mounted on the bracket 311 and connected to the pulley assembly 312, and is used to drive the moving component 32 to move along a second preset path W2 via the pulley assembly 312.

[0112] Since the power component 313 is mounted on the bracket 311 and connected to the pulley assembly 312, and the moving component 32 is connected to the pulley assembly 312, the power component 313 can drive the moving component 32 to move along the second preset path W2 via the pulley assembly 312. Because the pulley assembly 312 has a simple structure, the manufacturing cost of the drive component 31 can be reduced to a certain extent.

[0113] Specifically, the aforementioned pulley assembly 312 may include a driving pulley, a driven pulley, and a belt. The driving pulley is connected to the power component 313, the driven pulley is rotatably mounted on the bracket 311, and the belt is simultaneously fitted onto both the driving pulley and the driven pulley. The movable component 32 is connected to the belt. With this configuration, the power component 313 can drive the driving pulley to rotate. After the driving pulley rotates, it can drive the belt and the driven pulley to rotate. Since the movable component 32 is connected to the belt, when the belt rotates, it can drive the movable component 32 to move along the second preset path W2.

[0114] In this design, both the driving pulley and the driven pulley can be synchronous pulleys, and the belt can be a synchronous belt. This avoids the belt slipping relative to the driving pulley and the driven pulley, making the moving part 32 move more smoothly and reliably along the second preset path W2.

[0115] It should be noted that the aforementioned power component 313 can be a servo motor or a stepper motor, etc., and the embodiments of this application do not limit the power component 313.

[0116] In some embodiments, see Figure 2 The driving component 31 also includes a second guide rail 314, which is mounted on the bracket 311 and extends along the second preset path W2. The moving component 32 is slidably mounted on the second guide rail 314 along its extension direction. By mounting the second guide rail 314 on the bracket 311 and making it extend along the second preset path W2, and by making the moving component 32 slidably mounted on the second guide rail 314 along its extension direction, the movement of the moving component 32 along the second preset path W2 can be made more stable.

[0117] The second guide rail 314 can be a linear guide rail. When the second guide rail 314 is a linear guide rail, on the one hand, the manufacturing cost of the second guide rail 314 can be reduced due to the simple structure of the linear guide rail. On the other hand, it can also make the second preset path W2 a linear path, reducing the complexity of the second preset path W2.

[0118] Of course, the second guide rail 314 can also be a curved guide rail. When the second guide rail 314 is a curved guide rail, the second preset path W2 will also be a curved path.

[0119] In some embodiments, see Figure 1 The first preset path W1 and the second preset path W2 are parallel. By making the first preset path W1 and the second preset path W2 parallel, the movement of the door 1 and the movement of the moving part 32 will not interfere with each other, making the movement of the door 1 and the movement of the moving part 32 smoother.

[0120] The statement that the first preset path W1 and the second preset path W2 are parallel can be interpreted in a broad sense. That is, it is not strictly limited that the first preset path W1 and the second preset path W2 are parallel, but only that the first preset path W1 and the second preset path W2 are approximately parallel.

[0121] It should be noted that the movable component 32 and the compartment door 1 can be directly or indirectly detachably connected. When the movable component 32 and the compartment door 1 are indirectly detachably connected, in some embodiments, see [reference needed]. Figure 1 and Figure 3 The door opening and closing mechanism 100 also includes a connecting member 4, which is movably disposed on the door cover 201 along a direction parallel to the first preset path W1. The connecting member 4 is used for a detachable connection with the moving member 32. The connecting member 4 and the door 1 are relatively movable within a preset distance along a direction parallel to the first preset path W1.

[0122] In this embodiment, since the adapter 4 is movably disposed on the cover 201 along a direction parallel to the first preset path W1, and the adapter 4 and the movable member 32 are detachably connected, when the adapter 4 and the movable member 32 are in a connected state, when the movable member 32 is in the positive direction of the second preset path W2 ( Figure 2 When the X-axis moves (in the positive direction), the adapter 4 can move along the moving part 32 in a direction parallel to the second preset path W2. Since the adapter 4 and the door 1 are relatively movable within a preset distance along the direction parallel to the first preset path W1, when the distance that the adapter 4 moves along the direction parallel to the second preset path W2 with the moving part 32 is less than the preset distance, the adapter 4 can move relative to the door 1 in a direction parallel to the first preset path W1, while the door 1 remains stationary relative to the cover 201.

[0123] Specifically, please see Figure 1 If the distance that the adapter 4 moves along the direction parallel to the second preset path W2 is less than the preset distance, the adapter 4 can move relative to the cover 201 while the door 1 remains stationary relative to the cover 201.

[0124] For example, see Figure 1 and Figure 2The distance that the adapter 4 moves along the direction parallel to the second preset path W2, following the moving part 32, refers to the distance that the adapter 4 is in the position of... Figure 1 In the case of the leftmost position, the adapter 4 follows the moving member 32 and moves a distance in the positive direction parallel to the second preset path W2; or, the adapter 4 is in the position of Figure 2 In the case of the rightmost position, the adapter 4 follows the moving part 32 and moves in the opposite direction along the second preset path W2 by a distance.

[0125] When the distance that the adapter 4 moves along the direction parallel to the second preset path W2 is equal to the preset distance, the following is true. Figure 3 (Regarding the state of the intermediate connector 4), when the moving part 32 continues to move in a direction parallel to the second preset path W2, the intermediate connector 4 can be kept stationary relative to the door 1, and the door 1 relative to the cover 201 can be in the positive direction of the first preset path W1. Figure 1 Move to the first position (positive direction of the X-axis).

[0126] Since the adapter 4 and the movable part 32 are detachably connected, when the door 1 moves to the first position, if the movable part 32 continues to move in a direction parallel to the second preset path W2, the connection between the adapter 4 and the movable part 32 can be disconnected, thereby disconnecting the connection between the movable part 32 and the door 1. This also achieves the goal of making the movement between the movable part 32 and the door 1 either linked or independent.

[0127] It is worth noting that since the adapter 4 and the door 1 are relatively movable within a preset distance along a direction parallel to the first preset path W1, according to the above analysis, even if the moving part 32 moves a large distance along a direction parallel to the second preset path W2, the distance that the door 1 moves relative to the cover 201 along the first preset path W1 is still smaller than the distance that the moving part 32 moves along the second preset path W2. Thus, while ensuring that the moving part 32 moves a large distance along the second preset path W2, the stroke of the door 1 can be reduced, and the cover 201 can be designed to be smaller, thereby making the entire door opening and closing mechanism more compact.

[0128] In some embodiments, see Figure 1 The adapter 4 and the door 1 are connected relative to each other within a preset distance via the strip hole structure 41 along a direction parallel to the first preset path W1. Because the strip hole structure 41 has a simple structure, it can reduce the manufacturing cost of the door opening and closing mechanism 100 to a certain extent.

[0129] Of course, the adapter 4 and the compartment door 1 can also be connected relatively within a preset distance along a direction parallel to the first preset path W1 in other ways. For example, the adapter 4 and the compartment door 1 can also be connected relatively within a preset distance along a direction parallel to the first preset path W1 through the cooperation between the slide rail assembly and the limiting block. This application embodiment does not limit this.

[0130] When the adapter 4 and the door 1 are relatively movable within a preset distance through the strip hole structure 41 along a direction parallel to the first preset path W1, see [reference needed]. Figure 1 The strip hole structure 41 includes a strip hole 411 and a guide rod 412. The strip hole 411 is disposed on the adapter 4, and the guide rod 412 is disposed on the door 1. The guide rod 412 is located in the strip hole 411. The extension direction of the strip hole 411 is parallel to the first preset path W1, and the length of the strip hole 411 is equal to the preset distance.

[0131] Since the extension direction of the slot 411 is parallel to the first preset path W1, and the slot 411 is disposed on the adapter 4, with the root of the guide rod 412 disposed on the door 1 and the rod portion of the guide rod 412 suspended in the slot 411, when the guide rod 412 moves within the slot 411 along the extension direction of the slot 411, the adapter 4 and the door 1 can be relatively movable and connected in a direction parallel to the first preset path W1. Furthermore, since the length of the slot 411 is equal to the preset distance, the adapter 4 and the door 1 can be relatively movable and connected within a preset distance in a direction parallel to the first preset path W1.

[0132] As can be seen, when the strip hole structure 41 includes a strip hole 411 and a guide rod 412, and the length of the strip hole 411 is equal to the preset distance, the purpose of connecting the adapter 4 and the door 1 to be relatively movable within a preset distance along a direction parallel to the first preset path W1 can be achieved. The structure is very simple, and therefore, the manufacturing cost of the strip hole structure 41 can be reduced.

[0133] It should be noted that the above-mentioned strip hole 411 is provided on the adapter 4 and the guide rod 412 is provided on the door 1. This is only one possible implementation shown in this application. In other possible implementations, the strip hole 411 can be provided on the door 1 and the guide rod 412 can be provided on the adapter 4. This application does not limit this.

[0134] In some embodiments, see Figure 1A sealing gasket 2012 is provided on the edge of the opening 2011. When the door 1 is in the first position, the door 1 contacts the sealing gasket 2012 to seal the opening 2011. By providing a sealing gasket 2012 on the edge of the opening 2011, the door 1 contacts the sealing gasket 2012 when the door 1 is in the first position, thus sealing the opening 2011 and improving the sealing performance of the compartment 200, thereby improving the thermal insulation performance of the compartment 200.

[0135] The sealing gasket 2012 can be a rubber sealing gasket or a plastic sealing gasket, etc., and the embodiments of this application do not limit the sealing gasket 2012.

[0136] In some embodiments, see Figure 2 and Figure 3 The door opening and closing mechanism 100 also includes a second blocking part 5, which is disposed on the first preset path W1 and is used to block the door 1 at the second position when the door 1 moves in the reverse direction along the first preset path W1 to the second position. By providing the second blocking part 5, it is possible to prevent the door 1 from moving beyond the second position or even beyond the cover 201 when it moves in the reverse direction along the first preset path W1.

[0137] In some embodiments, see Figure 3 The first blocking part 2 is provided on the bin cover 201, and / or the second blocking part 5 is provided on the bin cover 201. By providing the first blocking part 2 and / or the second blocking part 5 on the bin cover 201, the structure of the entire bin door opening and closing mechanism 100 can be made more compact.

[0138] Of course, the fact that the first blocking part 2 is disposed on the compartment cover 201 and / or the second blocking part 5 is disposed on the compartment cover 201 is only one possible implementation shown in the embodiments of this application. In another possible implementation, the first blocking part 2 and the second blocking part 5 may also be disposed on other structures of the sample analyzer 300. The embodiments of this application do not limit this.

[0139] When both the first blocking part 2 and the second blocking part 5 are provided on the cover 201, in one possible implementation, see [reference needed]. Figure 2 The cover can be provided with a groove, and the door 1 can be slidably disposed in the groove along the first preset path W1. The two groove walls located on the first preset path W1 can respectively form the first blocking part 2 and the second blocking part 5.

[0140] By forming the first blocking part 2 and the second blocking part 5 respectively by making the two groove walls located on the first preset path W1 of the groove, the method of forming the first blocking part 2 and the second blocking part 5 is very simple, so the manufacturing cost of the first blocking part 2 and the second blocking part 5 can be reduced.

[0141] Of course, when both the first blocking part 2 and the second blocking part 5 are provided on the cover 201, the first blocking part 2 and the second blocking part 5 can also be two limiting blocks provided on the cover 201, etc., and this application embodiment does not limit this.

[0142] In some embodiments, see Figure 3 and Figure 4 The door 1 includes a first cover plate 13, a second cover plate 14, and an insulation plate 15. The second cover plate 14 is disposed opposite to the first cover plate 13 and is close to the opening 2011. The insulation plate 15 is located between the first cover plate 13 and the second cover plate 14, and the first cover plate 13 and the second cover plate 14 are connected.

[0143] By positioning the insulation board 15 between the first cover plate 13 and the second cover plate 14, the first cover plate 13 and the second cover plate 14 can protect the insulation board 15 from both sides, thereby preventing damage to the insulation board 15.

[0144] By setting up the insulation board 15, when the opening 2011 of the door 1 is closed, the door 1 can better insulate the compartment 200.

[0145] In some embodiments, the first cover plate 13 is a metal cover plate. Since the first cover plate 13 is farther away from the storage cover 201 than the second cover plate 14, by making the first cover plate 13 a metal cover plate, that is, by making the cover plate on the side farther away from the storage cover 201 a metal cover plate, the first cover plate 13 can protect the entire storage door 1, thereby making the entire storage door 1 stronger.

[0146] Specifically, the first cover plate 13 can be a stainless steel cover plate or an aluminum alloy cover plate, etc. The embodiments of this application do not limit the first cover plate 13.

[0147] The second cover plate 14 can be a plastic cover plate. Since the second cover plate 14 is close to the opening 2011, by making the second cover plate 14 a plastic cover plate, on the one hand, it can prevent the second cover plate 14 from damaging the compartment cover 201. On the other hand, it can also prevent the second cover plate 14 from being corroded and damaged.

[0148] The aforementioned insulation board 15 is an insulation cotton board. Since the insulation cotton board has a low cost and good insulation performance, it can improve the insulation performance of the warehouse door 1 while reducing the manufacturing cost of the warehouse door 1.

[0149] Example 2

[0150] Figure 5 This is a schematic diagram of a reagent adding device provided in an embodiment of this application. See also... Figure 5The reagent adding device 400 includes a door opening and closing mechanism 100.

[0151] The structure of the warehouse door opening and closing mechanism 100 provided in this application embodiment can be the same as that of any of the warehouse door opening and closing mechanisms 100 in the above embodiment one, and can bring the same or similar beneficial effects. For details, please refer to the description of the warehouse door opening and closing mechanism 100 in the above embodiment one. This application embodiment will not repeat the description here.

[0152] In this embodiment, by moving the movable member 32 along the second preset path W2 in either the forward or reverse direction, the door 1 can be moved along the first preset path W1 in the forward direction to a first position to close the opening 2011, or the door 1 can be moved along the first preset path W1 in the reverse direction to a second position to open the opening 2011. That is, the purpose of closing or opening the opening 2011 can be achieved. In this way, when the door opening / closing mechanism 100 is applied to a sample analyzer 300 with a compartment 200 and the opening 2011 is closed, the insulation performance of the compartment can be improved. Based on this, when the door opening / closing mechanism 100 is applied to a reagent adding device 400, the insulation performance of the reagent adding device 400 can be improved.

[0153] In some embodiments, see Figure 5 The reagent adding device 400 further includes: a reagent storage unit 401, a reagent picking unit 402 for picking up reagent bottles to be replaced, and a transfer tray 403 for buffering reagent bottles to be replaced. The reagent storage unit 401 includes a compartment 200 and a transport mechanism 4011 disposed within the compartment 200 for storing and transporting reagent bottles to be replaced. The transport mechanism 4011 is spaced apart from the compartment cover 201, and the transfer tray 403 is disposed on the movable component 32.

[0154] In this embodiment, since the conveying mechanism 4011 is located in the chamber 200, and the opening 2011 on the chamber cover 201 of the chamber 200 can be closed by the chamber door 1, the heat preservation performance of the entire reagent adding device 400 on the reagent bottle to be replaced on the conveying mechanism 4011 can be improved.

[0155] It should be noted that the aforementioned conveying mechanism 4011 can be a rotary conveying mechanism or a linear conveying mechanism, and this application embodiment does not limit it in this way.

[0156] It is worth noting that when the conveying mechanism 4011 is a rotary conveying mechanism, the volume of the entire reagent adding device 400 can be reduced to a certain extent because the rotary conveying mechanism has a compact structure.

[0157] It should also be noted that the reagent bottles to be replaced can be reagent bottles that have already been used on the transport mechanism 4011 and need to be removed, or they can be new reagent bottles provided by the user that need to be placed on the transport mechanism 4011.

[0158] In some embodiments, see Figure 1 and Figure 5 The movable component 32 can be used to move in the reverse direction along the second preset path W2, so as to drive the door 1 to move in the reverse direction along the first preset path W1 to the second position. The reagent pickup unit 402 is used to pick up the reagent bottle to be replaced on the transport mechanism 4011 through the opening 2011 and place the reagent bottle to be replaced in the transfer tray 403. The movable component 32 can also be used to move in the forward direction along the second preset path W2 to the third position, so as to drive the door 1 to the first position. The first blocking part 2 can separate the door 1 from the movable component 32 when the movable component 32 continues to drive the door 1 to move in the forward direction along the first preset path W1, so that the movable component 32 can drive the transfer tray 403 to extend out of the sample analyzer on its own.

[0159] In this embodiment, when it is necessary to transport the reagent bottle to be replaced on the transport mechanism 4011 to the outside of the sample analyzer 300, firstly, the reagent bottle to be replaced can be rotated to the opening 2011 by the transport mechanism 4011. After the reagent bottle to be replaced is rotated to the opening 2011, the moving part 32 can move in the opposite direction along the second preset path W2 to drive the door 1 to move in the opposite direction along the first preset path W1 to the second position, so that the opening 2011 opens. After the opening 2011 is opened, the reagent pickup unit 402 can pass through the opening 2011 on the transport mechanism. The reagent bottle to be replaced is picked up on 4011 and placed in the transfer tray 403. After the reagent bottle to be replaced is placed in the transfer tray 403, the moving part 32 can move to the third position along the second preset path W2 in the forward direction, so as to drive the door 1 to move to the first position, thereby closing the opening 2011. After the opening 2011 is closed, the first blocking part 2 can separate the door 1 from the moving part 32 when the moving part 32 continues to drive the door 1 to move along the first preset path W1 in the forward direction, so that the moving part 32 can continue to move along the second preset path W2 in the forward direction on its own.

[0160] Since the transfer tray 403 is mounted on the moving part 32, when the moving part 32 continues to move forward along the second preset path W2 on its own, it can simultaneously drive the transfer tray 403 to move until the transfer tray 403 extends out of the housing of the sample analyzer 300.

[0161] After the transfer tray 403 extends outside the housing of the sample analyzer 300, since the reagent bottle to be replaced is placed on the transfer tray 403, the transfer tray 403 can transport the reagent bottle to be replaced outside the housing of the sample analyzer 300.

[0162] After the reagent bottle to be replaced is transported outside the housing of the sample analyzer 300, it can be removed from the transfer tray 403 by manual means or by a robotic arm. Thus, the purpose of transporting the reagent bottle to be replaced from the transport mechanism 4011 to outside the housing of the sample analyzer 300 is achieved.

[0163] As described above, the movable component 32 can move the door 1 when it moves, thereby opening or closing the opening 2011. Furthermore, since the transfer tray 403 is mounted on the movable component 32, when the movable component 32 moves, it can also transport the reagent bottle to be replaced from the transport mechanism 4011 to outside the housing of the sample analyzer 300. Therefore, the movement of the movable component 32 can simultaneously achieve two functions without requiring a separate structure specifically for opening or closing the opening 2011, or a separate structure specifically for transporting the reagent bottle to be replaced from the transport mechanism 4011 to outside the housing of the sample analyzer 300. The structural design is ingenious, allowing the entire reagent adding device 400 to be relatively compact.

[0164] In addition, during the process of transporting the reagent bottle to be replaced from the transport mechanism 4011 to the outside of the sample analyzer 300, the transport mechanism 4011 can decide whether to rotate or stop rotating depending on the condition of the sample analyzer 300, without stopping the machine. Therefore, when the reagent adding device 400 is used in the sample analyzer, it will not affect the working efficiency of the sample analyzer.

[0165] In some embodiments, see Figure 5 The movable component 32 is used to move the transfer tray 403 carrying the reagent bottle to be replaced from outside the sample analyzer along the second preset path W2 in the reverse direction to the third position, so that the movable component 32 is detachably connected to the door 1. The movable component 32 is used to continue to move in the reverse direction along the second preset path W2, so as to drive the door 1 to move in the reverse direction along the first preset path W1 to the second position. The reagent picking unit 402 is used to pick up the reagent bottle to be replaced on the transfer tray 403 and place the reagent bottle to be replaced on the transport mechanism 4011 through the opening 2011.

[0166] In the embodiment of the application, when it is necessary to place the reagent bottle to be replaced on the transport mechanism 4011, firstly, when the transfer tray 403 extends outside the housing of the sample analyzer 300, the reagent bottle to be replaced can be placed on the transfer tray 403 manually or by a robotic arm. Then, the moving part 32 can move in the reverse direction of the second preset path W2 to a third position, allowing the moving part 32 to be detachably connected to the door 1. After the moving part 32 is detachably connected to the door 1, the moving part 32 can continue to move in the reverse direction of the second preset path W2, causing the door 1 to move in the reverse direction of the first preset path W1 to a second position, opening the opening 2011. After the opening 2011 is open, the reagent picking unit 402 can pick up the reagent bottle to be replaced from the transfer tray 403 and place it on the transport mechanism 4011 through the opening 2011. In this way, the purpose of transporting the reagent bottle to be replaced from outside the housing of the sample analyzer 300 to the transport mechanism 4011 can be achieved.

[0167] In some embodiments, see Figure 6 The reagent pickup unit 402 includes a first moving module 4021, a second moving module 4022, and a pickup head 4023. The second moving module 4022 is mounted on the first moving module 4021, and the first moving module 4021 drives the second moving module 4022 to move horizontally. The pickup head 4023 is mounted on the second moving module 4022. The first moving module 4021 drives the pickup head 4023 to move directly above the opening 2011 or directly above the transfer tray 403. The second moving module 4022 drives the pickup head 4023 to move vertically, so as to pick up the reagent bottle to be replaced from the transport mechanism 4011 through the opening 2011 and place the reagent bottle to be replaced on the transfer tray 403, or to pick up the reagent bottle to be replaced from the transfer tray 403 and place the reagent bottle to be replaced on the transport mechanism 4011 through the opening 2011.

[0168] In this embodiment, since the second moving module 4022 is disposed on the first moving module 4021 and the picking head 4023 is disposed on the second moving module 4022, the cooperation between the first moving module 4021 and the second moving module 4022 can achieve the purpose of picking up the reagent bottle to be replaced on the transport mechanism 4011 by the picking head 4023 and placing the reagent bottle to be replaced on the transfer tray 403, or picking up the reagent bottle to be replaced on the transfer tray 403 and placing the reagent bottle to be replaced on the transport mechanism 4011 through the opening 2011. The structure and principle are simple and the operation is reliable. Therefore, the operational reliability of the reagent picking unit 402 can be improved to a certain extent.

[0169] It should be noted that both the first moving module 4021 and the second moving module 4022 mentioned above can include a motor and a linear module. Of course, the first moving module 4021 and the second moving module 4022 can also have other possible structures, as long as the first moving module 4021 can drive the second moving module 4022 to move horizontally, and the second moving module 4022 can drive the pickup head 4023 to move vertically. This application embodiment does not limit this. For example, both the first moving module 4021 and the second moving module 4022 can also be linear cylinders, etc.

[0170] It is worth noting that, considering that the pickup head 4023 needs to pick up the reagent bottle to be replaced on the transport mechanism 4011 through the opening 2011, the transfer tray 403 needs to avoid the opening 2011 while ensuring that the opening 2011 is open, so that the pickup head 4023 can pick up the reagent bottle to be replaced on the transport mechanism 4011 through the opening 2011 without interfering with the transfer tray 403.

[0171] As described above, the adapter 4 is movably mounted on the cover 201 along a direction parallel to the first preset path W1. The adapter 4 is used for a detachable connection with the moving part 32. The adapter 4 and the door 1 are relatively movable within a preset distance along a direction parallel to the first preset path W1. The transfer tray 403 is mounted on the moving part 32. Based on this, assuming that the transfer tray 403 is initially located directly above the opening 2011, and further assuming that the pickup head 4023 needs to pick up the reagent bottle to be replaced on the conveying mechanism 4011 through the opening 2011, then the moving part 32 can first move the transfer tray 403 within a preset distance, so that the transfer tray 403 avoids the opening 2011 while the door 1 remains stationary. Then the opening 2011 will remain open, and in this way, the pickup head 4023 can achieve the purpose of picking up the reagent bottle to be replaced on the conveying mechanism 4011 through the opening 2011.

[0172] It can be seen that by making the adapter 4 and the door 1 relatively movable within a preset distance along a direction parallel to the first preset path W1, the transfer pallet 403 can avoid the opening 2011 while preventing the opening 2011 from being closed.

[0173] Moving component 32 drives adapter 4 to move to... Figure 1At the extreme position shown, the door 1 is moved to the second position by the adapter 4. At this time, the transfer tray 403 is directly above the opening 2011, and the pickup head 4023 can descend to grab the reagent bottle on the transfer tray 403. To avoid the pickup head 4023, the pickup head 4023 can move downwards, thereby placing the reagent bottle on the conveying mechanism 4011. The driving moving part 32 moves a preset distance (i.e., the length of the strip hole 411) in the positive direction along the second preset path W2, that is, moves to the position shown. Figure 3 As shown, this allows the transfer tray 403 to move away from directly above the opening 2011, enabling the pickup head 4023 to continue moving downwards and placing the reagent bottle onto the transport mechanism 4011. Due to the presence of the slot 411, the door 1 remains stationary during this avoidance process.

[0174] By cooperating with the guide rod 41 on the door through the strip hole 411, the adapter 4 can move under the drive of the moving part 32, and the door 1 can remain stationary for a preset distance without moving with the adapter 4. This can realize the function of the adapter 4 moving independently to avoid the opening 2011.

[0175] In some embodiments, see Figure 7 The pickup head 4023 is a gripper with multiple reagent bottle holding positions 4023a, each used to hold reagent bottles of different sizes. When the pickup head 4023 is a gripper, the reagent bottles can be held by clamping, which is simple in structure and provides stable clamping that prevents them from falling off. Therefore, the operational reliability of the entire reagent pickup unit 402 can be improved.

[0176] Of course, the pickup head 4023 can also be a suction nozzle or any other possible structure. This application embodiment does not limit the pickup head 4023.

[0177] By having the gripper have multiple reagent bottle holding positions 4023a, each holding a reagent bottle of a different size, the gripper can hold a wider range of reagent bottle sizes, thus enabling the reagent pickup unit 402 to pick up a wider range of reagent bottle sizes and improve compatibility.

[0178] The number of reagent bottle clamping positions 4023a can be 2, 3 or 4, etc., and this application embodiment does not limit this.

[0179] It should be noted that the aforementioned gripper can be a clamping cylinder. Of course, the gripper can be a mechanical gripper, etc., and the embodiments of this application do not limit the gripper.

[0180] In some embodiments, see Figure 8The transfer tray 403 includes a body 4031 and a connecting rod 4032. The body 4031 has a reagent bottle placement hole 4031a. The first end of the connecting rod 4032 is connected to the body 4031, and the second end of the connecting rod 4032 is connected to the movable component 32.

[0181] In this embodiment, by providing a reagent bottle placement hole 4031a on the main body 4031, when the reagent bottle is placed in the reagent bottle placement hole 4031a, the reagent bottle placement hole 4031a can limit the reagent bottle, so that the reagent bottle is placed very stably in the reagent bottle placement hole 4031a.

[0182] The reagent bottle placement holes 4031a are multiple, and the multiple reagent bottle placement holes 4031a form a stepped hole structure. When the number of reagent bottle placement holes 4031a is multiple and the multiple reagent bottle placement holes 4031a form a stepped hole structure, the transfer tray 403 can be compatible with reagent bottles of different specifications.

[0183] Specifically, the number of vials 4031a can be 2, 3 or 4, etc., and this application embodiment does not limit this.

[0184] In some embodiments, see Figure 8 The stepped hole structure has a notch 4031b on its hole wall. By providing the notch 4031b, which matches the protrusion on the reagent bottle (or an auxiliary component for supporting the reagent bottle), the notch 4031b serves two purposes: firstly, it prevents the reagent bottle from being misplaced in the reagent bottle placement hole 4031a; secondly, it ensures greater stability and reduces the likelihood of the reagent bottle shifting when placed in the hole 4031a.

[0185] Furthermore, in some embodiments, see Figure 8 The first end of the connecting rod 4032 is adjustablely connected to the body 4031. By making the first end of the connecting rod 4032 adjustablely connected to the body 4031, the relative position between the body 4031 and the connecting rod 4032 can be adjusted. This allows for flexible adjustment of the position of the body 4031 relative to the connecting rod 4032, making the structure of the entire transfer pallet 403 more flexible.

[0186] The first end of the connecting rod 4032 can be adjustablely connected to the body 4031 in a variety of ways. In one possible implementation, see [link to relevant documentation]. Figure 8The main body 4031 is provided with a positioning hole 4031c and an arc-shaped hole 4031d. The center of the circle containing the arc-shaped hole 4031d is concentric with the center of the positioning hole 4031c. The first end of the connecting rod 4032 is provided with a positioning post 4032a corresponding to the positioning hole 4031c and the arc-shaped hole 4031d, respectively. Figure 8 (not shown in the image) and threaded hole 4032b ( Figure 8 (Not shown in the image), the positioning pin 4032a is rotatably disposed in the positioning hole 4031c, and the screw 4033 is screwed into the threaded hole 4032b. Figure 8 (not shown in the image), the nut of screw 4033 is located on the side of the first end of the arc-shaped hole 4031d away from the connecting rod 4032.

[0187] Since the center of the circle containing the arc-shaped hole 4031d is concentric with the center of the positioning hole 4031c, the positioning post 4032a is rotatably disposed in the positioning hole 4031c. Therefore, the body 4031 can rotate around the positioning post 4032a relative to the first end of the connecting rod 4032, thereby achieving the purpose of adjustable connection between the first end of the connecting rod 4032 and the body 4031.

[0188] Since a screw 4033 is screwed into the threaded hole 4032b, and the nut of the screw 4033 is located on the side of the arc-shaped hole 4031d away from the first end of the connecting rod 4032, after the body 4031 rotates around the positioning post 4032a relative to the first end of the connecting rod 4032 to the target position, tightening the screw 4033 can fix the body 4031 to the first end of the connecting rod 4032, thereby preventing the body 4031 from deviating from the target position relative to the first end of the connecting rod 4032.

[0189] By cooperating with the positioning hole 4031c and the positioning post 4032a, and by cooperating with the arc-shaped hole 4031d, the threaded hole 4032b and the screw 4033, the first end of the connecting rod 4032 can be adjusted to be connected to the body 4031. The method is simple and therefore can reduce the manufacturing cost of the transfer pallet 403.

[0190] In some embodiments, see Figure 8 An anti-friction member 404 is provided on the side of the transfer tray 403 opposite to the second preset path W2. By providing the anti-friction member 404 on the side of the transfer tray 403 opposite to the second preset path W2, before the transfer tray 403 extends out of the housing of the sample analyzer 300, it can first contact the housing door of the sample analyzer 300 through the anti-friction member 404, so that the housing door is opened, and then the transfer tray 403 can extend out of the housing of the sample analyzer 300 through the housing door.

[0191] By incorporating anti-friction components 404, wear and tear on the transfer pallet 403 can be prevented.

[0192] In some embodiments, the anti-friction component 404 is an anti-friction wheel. By making the anti-friction component 404 an anti-friction wheel, the friction between the transfer tray 403 and the housing door of the sample analyzer 300 can be changed from sliding friction to rolling friction, thereby further reducing the friction between the transfer tray 403 and the housing door of the sample analyzer 300, and thus better preventing the transfer tray 403 from being worn.

[0193] Of course, the anti-friction component 404 can also be other possible components, such as a ball bearing, etc. This application embodiment does not limit this.

[0194] In some embodiments, see Figure 1 A recognition sensor 311 is provided on the drive unit 31. The recognition sensor 311 is used to identify the specifications of the reagent bottles on the transfer tray 403. By providing the recognition sensor 311 on the drive unit 31, the specifications of the reagent bottles on the transfer tray 403 can be identified in real time. In this way, when the reagent picking unit 402 picks up the reagent bottles on the transfer tray 403, it can pick up the reagent bottles more effectively according to their specifications.

[0195] For example, assuming the identification sensor 311 identifies the reagent bottle on the transfer tray 403 as a smaller size, then when the reagent pickup unit 402 picks up the smaller reagent bottle from the transfer tray 403, the pickup head 4023 can move a greater distance downwards in the vertical direction so that the pickup head 4023 can pick up the smaller reagent bottle. Conversely, assuming the identification sensor 311 identifies the reagent bottle on the transfer tray 403 as a larger size, then when the reagent pickup unit 402 picks up the larger reagent bottle from the transfer tray 403, the pickup head 4023 can move a smaller distance downwards in the vertical direction to avoid the pickup head 4023 colliding with the reagent bottle due to excessive downward movement.
