DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solutions and advantages of the present application more clear and understandable, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0055] In the specific embodiments, various specific technical features described can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by the combination of different specific technical features. In order to avoid unnecessary repetition, various possible combinations of various specific technical features in the present application are not described again.

[0056] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related aspects. It should be understood that the terms "upper", "lower", "outer", "inner" refer to the position in the normal use state, and the terms "left" and "right" refer to the left and right directions shown in the specific schematic diagram, which can be the left and right directions in the normal use state or not.

[0057] It should be noted that the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element. "Multiple" means two or more.

[0058] The embodiments of the present application provide a sample analyzer, which can be an IVD (in vitro diagnostic) device commonly applied in the field of in vitro diagnostic technology to assist clinical diagnosis.

[0059] Please refer to Figure 1 and Figure 3 , the sample analyzer comprises a main housing 11, a housing panel 50 and a rack 40. The main housing 11 is arranged on the rack 40 and has an inner cavity 11b and an opening 11a, and the housing panel 50 is used to open or close the opening 11a.

[0060] The manner in which the housing panel 50 opens or closes the opening 11a is not limited. For example, the housing panel 50 can rotate relative to the main housing 11 to open or close the opening 11a; or the housing panel 50 can translate relative to the main housing 11 to open or close the opening 11a; or the housing panel 50 can have both translation and rotation relative to the main housing 11.

[0061] For example, the rack 40 is a support member of the sample analyzer, which is used to provide support to the surrounding component structure, and the main housing 11 is an appearance member of the sample analyzer, which is used to separate the internal space of the sample analyzer from the external environment, so that a relatively closed inner cavity 11b is formed inside the sample analyzer.

[0062] Please refer to Figure 3 , Figure 4 and Figure 5The sample analyzer further comprises a detection device (not shown in the figure). The detection device is arranged in the inner cavity 11b of the main housing 11, and is used to detect the sample to obtain a sample detection result. Exemplarily, the sample analyzer further comprises a scheduling mechanism, a sample dispensing mechanism, and a reagent dispensing mechanism. The scheduling mechanism schedules the sample to a sample dispensing position, the sample dispensing mechanism dispenses the sample in the sample container to a reaction container, the reagent dispensing mechanism dispenses the reagent in the reagent container to the reaction container, and the reaction container containing the sample and the reagent is scheduled to a detection position by the scheduling mechanism, so that the detection device is used to detect the reaction liquid containing the sample and the reagent in the reaction container to obtain the detection result of the sample, thereby assisting clinical diagnosis.

[0063] The sample analyzer further comprises a drawer structure 21 and a locking mechanism 30.

[0064] The drawer structure 21 is arranged below the housing panel 50 and adjacent to the housing panel 50 in the height direction (i.e., the up-down direction shown in the figure). The drawer structure 21 has a push-pull surface 21a for driving the drawer structure 21 to move in a first direction under the action of a push-in force or a pull-out force. The first direction intersects the height direction. The drawer structure 21 is used to expand the accommodation function of the sample analyzer. Exemplarily, an operator can pull the push-pull surface 21a in the first direction to open the drawer structure 21, and put corresponding articles into the drawer structure 21. The operator can also push the push-pull surface 21a in the first direction to close the drawer structure 21, and store corresponding articles inside the instrument for standby use.

[0065] Exemplarily, the outer side surface of the housing panel 50 and the push-pull surface 21a of the drawer structure 21 are exposed outside the sample analyzer. When the operator pushes or pulls the drawer structure 21, the outer side surface of the housing panel 50 and the push-pull surface 21a of the drawer structure 21 face the operator.

[0066] Please refer to Figure 3 The locking mechanism 30 is arranged on the inner side of the housing panel 50 and connected with the housing panel 50. The housing panel 50 provides a mounting position and support for the locking mechanism 30. When the housing panel 50 moves relative to the main housing 11, the housing panel 50 moves together with the locking mechanism 30.

[0067] The locking mechanism 30 comprises a locking piece 31 for locking the housing panel 50 to the rack 40. It can be understood that, when the locking piece 31 locks the housing panel 50 to the rack 40, the housing panel 50 is fixed relative to the main housing 11, so that the housing panel 50 can be kept at a position closing the opening 11a. When the locking piece 31 releases the locking of the housing panel 50, the housing panel 50 can be driven to move, so that the housing panel 50 can open the opening 11a.

[0068] Please refer toFigure 3 and Figure 7 The locking member 31 includes a force applying part 311, which is exposed to the bottom side of the housing panel 50, i.e. the side of the housing panel 50 facing the push-pull surface 21a. The force applying part 311 is used to move the locking member 31 under the action of an external force, so as to lock or unlock the housing panel 50 and the rack 40. That is, the force applying part 311 is not directly exposed to the side surface of the housing panel 50 facing the operator, but is located at the bottom side which is not easily noticed. Thus, the force applying part 311 is not arranged on the outer side surface of the housing, so that the appearance surface is more complete and simple, the aesthetic property is better, and the disinfection and cleaning are facilitated, and the sealing property of the instrument housing is maintained.

[0069] When the drawer structure 21 is pulled open under the action of a pulling force, the internal space of the drawer structure 21 is opened, the force applying part 311 faces the internal space of the drawer structure 21, and an external force applying object applies an external force to the force applying part 311 by means of the internal space of the drawer structure 21, so as to move the locking member 31 and unlock the housing panel 50 and the rack 40. That is, after the drawer structure 21 is pulled open, a space for operating the force applying part 311 is provided, and the operator first pulls open the drawer structure 21 before unlocking the housing panel 50 and the rack 40 by means of the force applying part 311. Before the drawer structure 21 is not pulled open, the push-pull surface 21a and the housing panel 50 can maintain a small distance in the height direction, so that the position of the force applying part 311 is hidden, and the appearance layout is more compact.

[0070] The external force applying object includes but is not limited to the hand of the operator or a tool used by the operator.

[0071] Exemplarily, when the opening and closing port 11a is opened, the operator can maintain or inspect the inside of the sample analyzer through the opening and closing port 11a.

[0072] In an embodiment, the force applying part 311 needs to be operated after the drawer structure 21 is pulled open, so that a necessary step is set before the opening and closing port 11a is opened, and the risk of exposing the medical staff due to misoperation is reduced. On the other hand, the internal space of the drawer structure 21 is reused to operate the force applying part, so that the operation space of the force applying part is small, the drawer structure 21 can be more compactly close to the housing panel 50, and the appearance of the sample analyzer is more beautiful.

[0073] Exemplarily, as shown in Figure 2As shown, when the drawer structure 21 is moved to the inner cavity 11b of the main shell 11 under the push force and is in place, the distance a between the push-pull surface 21a and the bottom end surface of the shell panel 50 in the height direction is not more than 2 cm (centimeters), including but not limited to 2 cm, 1.5 cm, 1 cm, 0.5 cm, etc. Thus, the distance between the drawer structure 21 and the shell panel 50 is close, the hiding effect of the force applying part 311 is good, and the compactness of the structural layout is ensured.

[0074] In some embodiments, as shown in Figure 4 and Figure 5 , the force applying part 311 is configured to drive the locking piece 31 to rotate under the action of an external force to achieve or release the locking of the shell panel 50 and the rack 40. That is, the locking piece 31 changes its angular position by rotating to achieve or release the locking with the rack 40.

[0075] In some embodiments, as shown in and

[0076] , the locking piece 31 includes a rotating shaft 312 and a locking hook 313 connected with each other, the rack 40 is connected with a locking hook seat 41, and the rotating shaft 312 is configured to drive the locking hook 313 to rotate under the action of an external force to achieve or release the locking of the locking hook 313 and the locking hook seat 41. When the locking hook 313 and the locking hook seat 41 are locked, the shell panel 50 and the rack 40 are locked. When the locking hook 313 and the locking hook seat 41 are released, the shell panel 50 and the rack 40 are released.

[0077] In some embodiments, as shown in Figure 4 and Figure 5 , the rotating axis of the locking piece 31 (as shown by the center line in the figure) is parallel to the height direction, which facilitates the external force applying object to operate the force applying part 311 on the bottom side of the shell panel 50.

[0078] In some other embodiments, the rotating axis of the locking piece 31 can be perpendicular to the height direction.

[0079] In some embodiments, as shown in Figure 4 and Figure 5 , the inner side of the shell panel 50 is connected with a bracket 51, the bracket 51 is provided with a through hole 121a, and the rotating shaft 312 passes through the through hole 121a. That is, the shell panel 50 connects the locking mechanism 30 through the bracket 51. Thus, the manufacturing and modeling requirements of the shell panel 50 can be reduced, and the design flexibility of the shell panel 50 is improved.

[0080] For example, referring to Figure 6 and Figure 7 , the outer periphery of the rotating shaft 312 has at least one annular groove 312a, and the number of the annular grooves 312a can be one, two or more, which is not limited herein.

[0081] The locking mechanism 30 further comprises a clamping spring 33 clamped into the annular groove 312a, and the number of the clamping spring 33 is at least one. The clamping spring 33 is used to limit the axial displacement of the rotating shaft 312, so as to reduce the possibility of the rotating shaft 312 moving along the height direction. The rotating shaft 312 is used to rotate relative to the clamping spring 33 under the action of an external force to drive the locking hook 313 to rotate, and the clamping spring 33 does not need to rotate with the rotating shaft 312.

[0082] In some embodiments, the rotating direction ω of the rotating shaft 312 includes an unlocking direction and a locking direction, and the unlocking direction is opposite to the locking direction, referring to Figure 4 and Figure 5 .

[0083] Referring to Figure 4 and Figure 5 , the locking mechanism 30 further comprises a reset member 32 used to exert a reset force on the locking member 31 at least in the case that the locking hook 313 is unlocked from the hook seat 41. When an external force acts on the force applying part 311, the rotating shaft 312 rotates in the unlocking direction under the action of the external force to unlock the locking hook 313 from the hook seat 41. When the external force is removed, the rotating shaft 312 rotates in the locking direction under the action of the reset force to realize the locking of the locking hook 313 and the hook seat 41. That is, when the external force is removed, the rotating shaft 312 can be automatically reset under the action of the reset force, without the need for manual reset by an operator, so as to reduce the complexity of operation and ensure the safety of operation.

[0084] For example, in an embodiment, the reset member 32 also exerts a reset force on the locking member 31 in the case that the locking hook 313 is locked with the hook seat 41, and the reset force always hinders the rotating shaft 312 from rotating in the unlocking direction. In other embodiments, the reset member 32 does not exert a reset force on the locking member 31 in the case that the locking hook 313 is locked with the hook seat 41, and the reset member 32 only exerts a reset force on the locking member 31 after the locking member 31 deviates from the locking position.

[0085] In some embodiments, the reset member 32 comprises a torsion spring sleeved on the outer periphery of the rotating shaft 312. When the rotating shaft 312 rotates in the unlocking direction, the torsion spring is twisted and elastically deformed to store the reset force, i.e., the elastic force. The rotating shaft 312 is sleeved in the torsion spring, so that the structure is compact and the space occupation is small.

[0086] In some other embodiments, the reset member 32 can also be in the form of an elastic rope, a cylindrical spring, a spring sheet, or a coil spring.

[0087] In some embodiments, referring to Figure 7 , the bottom end surface of the rotating shaft 312 is provided with a non-circular driving hole for the insertion of the unlocking member 200 from the internal space of the drawer structure 21 located below the housing panel 50 to drive the rotating shaft 312 to rotate. After the unlocking member 200 is inserted into the driving hole, the unlocking member 200 rotates to drive the rotating shaft 312 to rotate due to the circumferential limiting effect of the non-circular hole, thereby transmitting the power of the unlocking member 200 to the locking hook 313. In this embodiment, the driving hole can be understood as the force applying part 311 described above.

[0088] Exemplarily, the non-circular hole can be a hexagonal hole, a triangular hole, or a cross-groove hole.

[0089] Exemplarily, the unlocking member 200 includes a hexagonal wrench.

[0090] Of course, in other embodiments, the cross section of the bottom end of the rotating shaft 312 can be polygonal, and the unlocking member 200 can be a sleeve wrench, which is sleeved on the bottom end of the rotating shaft 312 to drive the rotating shaft 312 to rotate. In this embodiment, the structure of the bottom end of the rotating shaft 312 can be understood as the force applying part 311 described above.

[0091] In some embodiments, referring to Figure 6 , the locking hook seat 41 has a stop structure 411, when the locking hook 313 abuts against the stop structure 411 in the movement direction of the housing panel 50 during the movement of the housing panel 50 from the open state of the opening and closing opening 11a to the closed state of the opening and closing opening 11a, the locking hook 313 rotates in the unlocking direction under the abutting action of the stop structure 411 to avoid the stop structure 411. The housing panel 50 can continue to move in the direction of closing the opening and closing opening 11a; the locking hook 313 continues to move with the movement of the housing panel 50, after the locking hook 313 passes the stop structure 411, the rotating shaft 312 rotates in the locking direction under the action of the reset member 32 to lock the locking hook 313 on the stop structure 411, thereby realizing the automatic locking of the housing panel 50 and the rack 40. Thus, when the housing panel 50 closes the opening and closing opening 11a, the stop structure 411 interacts with the locking mechanism 30 to automatically reset and re-lock the housing panel 50 as the housing panel 50 moves into place without operating the force applying part 311.

[0092] At least one of the stop structure 411 and the locking hook 313 has an inclined guide surface 411a, which causes the reaction force exerted by the stop structure 411 on the locking hook 313 to have a component force that causes the locking hook 313 and the rotating shaft 312 to rotate in the unlocking direction, thereby converting the displacement of the housing panel 50 into the rotation of the locking hook 313.

[0093] Exemplarily, please refer to Figure 6 The stop structure 411 has an inclined guide surface 411a facing the surface of the housing panel 50.

[0094] Exemplarily, the locking hook 313 has an inclined guide surface 411a facing away from the surface of the housing panel 50.

[0095] Exemplarily, the stop structure 411 has an inclined guide surface 411a facing the surface of the housing panel 50, and the locking hook 313 has an inclined guide surface 411a facing away from the surface of the housing panel 50.

[0096] In some embodiments, the sample analyzer further comprises an elastic sealing strip, the housing panel 50 has a first sealing surface, and the main housing 11 and / or the rack 40 has a second sealing surface, that is, part or all of the second sealing surface is located on the main housing 11, or part or all of the second sealing surface is located on the rack 40, and the first sealing surface and the second sealing surface both surround the opening and closing port 11a.

[0097] When the housing panel 50 is locked to the rack 40, the elastic sealing strip is arranged between the first sealing surface and the second sealing surface and is in a compressed state. The elastic sealing strip is elastically deformed under the action of the first sealing surface and the second sealing surface, and tries to keep in close contact with the first sealing surface and the second sealing surface to enhance the sealing of the sample analyzer, so that the inside of the housing assembly 10 is isolated from the outside environment, thereby maintaining the stability of the internal conditions of the housing assembly 10, and further ensuring the stability of the instrument operation.

[0098] When the locking member 31 releases the locking of the housing panel 50 and the rack 40, the elastic sealing strip recovers the elastic deformation and moves the housing panel 50 away from the rack 40 under the action of its own elastic force. Thus, when the external force object operates the force applying part 311 to release the locking of the housing panel 50, the housing panel 50 can automatically pop up from the rack 40, thereby reducing the operation amount of the external force object and facilitating the opening of the opening and closing port 11a.

[0099] The present application also provides a sample analyzer, please refer to Figure 1 and Figure 3 The sample analyzer comprises a housing assembly 10 and a housing panel 50. The housing assembly 10 has an opening and closing port 11a, and the housing panel 50 is used to open or close the opening and closing port 11a. Exemplarily, the housing panel 50 rotates relative to the housing assembly 10 to open or close the opening and closing port 11a. Alternatively, the housing panel 50 translates relative to the housing assembly 10 to open or close the opening and closing port 11a. Alternatively, the housing panel 50 has both translation and rotation relative to the main housing 11.

[0100] Please refer toFigure 3 、 Figure 4 and Figure 5 The sample analyzer further comprises a detection device. The detection device is disposed inside the housing assembly 10, and is configured to detect the sample to obtain a sample detection result. Exemplarily, the sample analyzer further comprises a scheduling mechanism, a sample dispensing mechanism, and a reagent dispensing mechanism. The scheduling mechanism schedules the sample to a sample dispensing position, the sample dispensing mechanism dispenses the sample in the sample container to a reaction container, the reagent dispensing mechanism dispenses the reagent in the reagent container to the reaction container, the reaction container containing the sample and the reagent is scheduled to a detection position by the scheduling mechanism, and the detection device is configured to detect the reaction liquid containing the sample and the reagent in the reaction container to obtain the detection result of the sample, thereby assisting clinical diagnosis.

[0101] The sample analyzer further comprises a pulling member 20 and a locking mechanism 30.

[0102] The pulling member 20 has a push-pull surface 21a configured to move the pulling member 20 relative to the housing assembly 10 along a first direction under the action of a push-in force or a pull-out force. The pulling member 20 is arranged adjacent to the housing panel 50 in a second direction. The first direction intersects the second direction; and the first direction is perpendicular to the second direction. Exemplarily, an operator can pull the push-pull surface 21a along the first direction, so that at least a part of the pulling member 20 extends out of the housing assembly 10.

[0103] Referring to Figure 3 The locking mechanism 30 is connected with the housing panel 50 and disposed inside the housing panel 50. The housing panel 50 provides a mounting position and support for the locking mechanism 30. When the housing panel 50 moves relative to the main housing 11, the housing panel 50 moves together with the locking mechanism 30.

[0104] The locking mechanism 30 comprises a locking member 31 configured to lock the housing panel 50 to the housing assembly 10. It can be understood that, when the locking mechanism 30 locks the housing panel 50 to the housing assembly 10, the housing panel 50 is kept at a position closing the opening 11a, and when the locking mechanism 30 releases the locking of the housing panel 50, the housing panel 50 can be driven to move, so that the housing panel 50 can open the opening 11a.

[0105] Referring to Figure 3 and Figure 7The locking member 31 has a force applying part 311, which is exposed to the side of the housing panel 50 facing the pulling member 20, i.e. exposed to the side of the housing panel 50 facing the push-pull surface 21a. The force applying part 311 is used to drive the locking member 31 to move under the action of an external force, so as to lock or unlock the housing panel 50 and the housing assembly 10. That is, the force applying part 311 is not directly exposed to the side surface of the housing panel 50 facing the operator, so that the force applying part 311 is not arranged on the outer side surface of the housing, which makes the appearance more complete and simple, has better aesthetic property, and is convenient for disinfection and cleaning. In addition, the pulling member 20 is relatively close to the housing panel 50, which is conducive to hiding the force applying part 311.

[0106] Exemplarily, the second direction can be any direction in the plane perpendicular to the first direction. For example, in some embodiments, the first direction is the front-rear direction of the sample analyzer, and the second direction can be the left-right direction, i.e. the pulling member 20 and the housing panel 50 are arranged adjacent along the left-right direction; or the height direction (i.e. the up-down direction), i.e. the pulling member 20 and the housing panel 50 are arranged adjacent along the height direction; or any direction between the left-right direction and the height direction.

[0107] In some specific embodiments, the second direction is the height direction of the sample analyzer, the pulling member 20 is arranged below the housing panel 50, the normal line of the outer side surface of the housing panel 50 extends along the first direction, and the outer side surface of the housing panel 50 faces the operator when the operator operates the pulling member 20, i.e. the outer side surface of the housing panel 50 is the appearance surface.

[0108] Exemplarily, the force applying part 311 is exposed to the bottom side of the housing panel 50, so as to be operated by an external force object to unlock the housing panel 50 and the housing assembly 10.

[0109] The specific structure of the pulling member 20 is not limited. Exemplarily, the pulling member 20 comprises a drawer structure 21, which is extended out of the housing assembly 10 along the first direction, and the internal space of the drawer structure 21 is open, so that the operator can put articles into the drawer structure 21; the operator can also push the push-pull surface 21a along the first direction to close the drawer structure 21, so as to store the corresponding articles inside the instrument for standby.

[0110] When the puller 20 is pulled open under the action of the pulling force, the force applying part 311 is directed towards the inner space of the puller 20, and the external force applying object applies an external force to the force applying part 311 by means of the inner space of the puller 20, so as to drive the locking piece 31 to move and release the locking of the shell panel 50 and the shell assembly 10. That is, after the puller 20 is pulled open, a space for operating the force applying part 311 is provided, and the puller 20 is pulled open before the locking of the shell panel 50 and the shell assembly 10 is released by the force applying part 311. Before the puller 20 is not pulled open, the push-pull surface 21a and the shell panel 50 can maintain a small distance in the height direction, the structure layout is more compact, the position of the force applying part 311 is more concealed, and it is difficult to be exposed in the field of view of the operator.

[0111] The external force applying object described above includes but is not limited to the hands of the operator or tools used by the operator.

[0112] Exemplarily, when the opening and closing opening 11a is opened, the operator can inspect or maintain the inside of the sample analyzer through the opening and closing opening 11a. In an embodiment, the puller 20 needs to be pulled open before the force applying part 311 is operated, so that a necessary step can be set before the opening and closing opening 11a is opened, and the risk of misoperation is reduced. On the other hand, the internal space of the puller 20 is reused to operate the force applying piece, so that the operation space required by the force applying piece is small, the puller 20 can be more compactly close to the shell panel 50, and the appearance of the sample analyzer is more beautiful.

[0113] In some embodiments, please refer to Figure 4 and Figure 5 , the force applying part 311 is used to drive the locking piece 31 to rotate under the action of the external force, so as to realize or release the locking of the shell panel 50 and the rack 40. That is, the locking piece 31 changes its angular position by rotating, so as to realize or release the locking of the shell assembly 10.

[0114] Among them, the locking piece 31 includes a rotating shaft 312 and a locking hook 313 connected with each other, the rack 40 is connected with a locking hook seat 41, and the rotating shaft 312 is used to drive the locking hook 313 to rotate under the action of the external force, so as to realize or release the locking of the locking hook 313 and the locking hook seat 41. When the locking hook 313 and the locking hook seat 41 are locked, the locking of the shell panel 50 and the shell assembly 10 is realized, and when the locking hook 313 and the locking hook seat 41 are released, the locking of the shell panel 50 and the shell assembly 10 is released.

[0115] In some embodiments, the rotating direction ω of the rotating shaft 312 includes an unlocking direction and a locking direction, the unlocking direction is opposite to the locking direction, please refer to Figure 4 and Figure 5 .

[0116] Please refer to Figure 4 and Figure 5The locking mechanism 30 further comprises a reset member 32 configured to apply a reset force to the locking member 31 at least when the locking hook 313 is unlocked from the locking hook seat 41. When an external force is applied to the force applying portion 311, the rotating shaft 312 rotates in the unlocking direction under the action of the external force to unlock the locking hook 313 from the locking hook seat 41. When the external force is removed, the rotating shaft 312 rotates in the locking direction under the action of the reset force to lock the locking hook 313 to the locking hook seat 41. That is, when the external force is removed, the rotating shaft 312 can be automatically reset under the action of the reset force without manual reset by an operator. Illustratively, the reset member 32 applies a reset force to the locking member 31 when the locking hook 313 is locked to the locking hook seat 41, which always prevents the rotating shaft 312 from rotating in the unlocking direction. In other embodiments, the reset member 32 does not apply a reset force to the locking member 31 when the locking hook 313 is locked to the locking hook seat 41, and the reset member 32 applies a reset force to the locking member 31 only after the locking member 31 deviates from the locking position.

[0117] In some embodiments, referring to Figure 6 The locking hook seat 41 has a stop structure 411. During the movement of the housing panel 50 from the open state to the closed state of the opening and closing opening 11a, when the locking hook 313 abuts against the stop structure 411 in the movement direction of the housing panel 50, the locking hook 313 rotates in the unlocking direction under the abutting action of the stop structure 411 to avoid the stop structure 411, so that the housing panel 50 can continue to move. The locking hook 313 moves with the movement of the housing panel 50, and after the locking hook 313 passes the stop structure 411, the rotating shaft 312 rotates in the locking direction under the action of the reset member 32 to lock the locking hook 313 to the stop structure 411. Thus, when the housing panel 50 closes the opening and closing opening 11a, the stop structure 411 interacts with the locking mechanism 30 to automatically reset the locking member 31 to re-lock the housing panel 50 as the housing panel 50 is moved into position.

[0118] In some embodiments, the sample analyzer further comprises a top opening structure configured to apply a force to the housing panel 50 in the direction of the opening and closing opening 11a at least when the housing panel 50 is locked to the housing assembly 10, and to push at least a portion of the housing panel 50 away from the housing assembly 10 when the housing panel 50 is unlocked from the housing assembly 10. Thus, when an external force applying object operates the force applying portion 311 to unlock the housing panel 50, the housing panel 50 can be automatically pushed away from the housing assembly 10, thereby reducing the amount of operation of the external force applying object to open the opening and closing opening 11a.

[0119] The specific form of the top opening structure is not limited.

[0120] Exemplarily, in an embodiment, the top-opening structure comprises a spring, one end of the spring is connected to the housing assembly 10, and the other end of the spring is in separable abutment with the housing panel 50. When the housing panel 50 is locked to the housing assembly 10, the spring is in a compressed state, and when the locking of the housing panel 50 to the housing assembly 10 is released, the spring restores the elastic deformation and exerts an elastic force on the housing panel 50 to push the housing panel 50 away from the housing assembly 10.

[0121] Exemplarily, in an embodiment, the sample analyzer further comprises an elastic sealing strip, the housing panel 50 has a first sealing surface, and the housing assembly 10 has a second sealing surface. When the housing panel 50 is locked to the housing assembly 10, the elastic sealing strip is arranged between the first sealing surface and the second sealing surface and is in a compressed state, and the elastic sealing strip is elastically deformed under the action of the first sealing surface and the second sealing surface to try to keep in close contact with the first sealing surface and the second sealing surface to enhance the sealing of the sample analyzer and isolate the inside of the housing assembly 10 from the outside environment; when the locking of the housing panel 50 to the housing assembly 10 is released by the locking member 31, the elastic sealing strip drives the housing panel 50 to move away from the housing assembly 10 under the action of its own elastic force.

[0122] Exemplarily, in an embodiment, the top-opening structure comprises a first magnetic force structure arranged on the housing assembly 10 and a second magnetic force structure arranged on the housing panel 50, and the first magnetic force structure and the second magnetic force structure generate repulsive magnetic force. When the locking of the housing panel 50 to the housing assembly 10 is released by the locking member 31, the magnetic force drives the housing panel 50 to move away from the housing assembly 10.

[0123] The sample analyzer of the embodiments of the present application can refer to the description of the first sample analyzer in the foregoing description for more specific embodiments, which will not be described here.
