TECHNICAL FIELD

[0001] The present application relates to the field of in-vitro diagnostic equipment, in particular to a microorganism detector. BACKGROUND

[0002] The microorganism detector mainly incubates the sample in the sample container by at least one incubation assembly, and detects the growth of microorganisms in the sample by a detection assembly. The incubation assembly is a drawer type structure installed inside the housing assembly. An operator can put in and take out the sample container by pushing and pulling the incubation assembly out of the incubation cavity, and push the incubation assembly back into the incubation cavity.

[0003] However, in the closing process of the existing incubation assembly, the incubation assembly and / or the panel are easily collided with the cabinet due to excessive external force, and even the incubation assembly and / or the panel are bounced open, which cannot guarantee the stability of the entire microorganism detector during operation, so that the sample container placed in the incubation assembly is damaged, or the sealing requirement of incubation cannot be met after the incubation assembly and / or the panel are bounced open, thereby affecting the incubation effect. CONTENT OF THE UTILITY MODEL

[0049] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0050] According to a first aspect of the present application, as Figure 1 and Figure 2As shown, the present application provides a microorganism detector, which comprises a housing assembly 10 and an incubation assembly 20. The housing assembly 10 is internally formed with an incubation cavity, and the incubation assembly 20 is movably installed in the incubation cavity and used to carry a plurality of sample containers containing samples for incubation in the incubation cavity.

[0051] It should be noted that the number of incubation cavities can be one or more than one, and each incubation cavity can be installed with one incubation assembly 20 or more than one incubation assembly 20, which is not limited by the present application.

[0052] In an optional embodiment, the microorganism detector further comprises a detection assembly installed on the incubation assembly 20 to detect the growth of microorganisms in the sample containers.

[0053] For example, the housing assembly 10 comprises a cabinet 11 and a panel 12. The incubation cavity is formed in the interior of the cabinet 11, and the panel 12 cooperates with the cabinet 11 to open or close the incubation cavity. The incubation cavity is mainly used to provide a space for the incubation assembly 20.

[0054] In an optional embodiment, the incubation assembly 20 is configured to move relative to the cabinet 11 under the action of an external force between an open position and a closed position. In the open position, the incubation assembly 20 is at least partially exposed outside the cabinet 11 to facilitate the placement and removal of the sample containers. In the closed position, the incubation assembly 20 is accommodated in the incubation cavity to incubate the samples in the sample containers.

[0055] It should be noted that the external force can be a manual force, an electric drive force, a pneumatic drive force, or a hydraulic drive force.

[0056] In a specific application, when the incubation assembly 20 is in the open position, an operator or an operating robot can perform the operation of placing the sample containers and the operation of removing the sample containers in the incubation assembly 20. In the present embodiment, the incubation assembly 20 is movably connected to the cabinet 11 and can move between the open position and the closed position, which facilitates the movement of the incubation assembly 20 to a position that is convenient for the operation of placing the sample containers and the operation of removing the sample containers.

[0057] In an optional embodiment, as shown in FIG. 2, the incubation assembly 20 comprises a plurality of incubation units 21, and each incubation unit 21 is configured to carry a plurality of sample containers. Figure 3 and Figure 4As shown, the microorganism detector comprises a magnetic attraction mechanism 40, which is at least partially arranged in the cabinet 11. When the incubation assembly 20 approaches the closed position, the magnetic attraction mechanism 40 is used to provide a magnetic attraction force to attract the incubation assembly 20 to the cabinet 11, so as to effectively close the incubation assembly 20, making the closing of the incubation assembly 20 more labor-saving and convenient, avoiding the operator from accidentally forgetting to close the incubation assembly 20, and ensuring that the incubation assembly 20 is in closer contact with the cabinet 11 when in the closed position, thereby improving the sealing between the incubation assembly 20 and the cabinet 11 to meet the sealing requirements of the incubation environment. At the same time, without external force, the incubation assembly 20 does not need to worry about being separated from the cabinet 11, and the operation is convenient.

[0058] When the panel 12 is closed, the magnetic attraction mechanism 40 is used to provide a magnetic attraction force to attract the panel 12 to the cabinet 11, so as to make the closing of the panel 12 more labor-saving and convenient, avoid the operator from accidentally forgetting to close the panel 12, and ensure that the panel 12 is in closer contact with the cabinet 11 when closed, thereby improving the sealing between the panel 12 and the cabinet 11 to meet the sealing requirements of the incubation environment. At the same time, without external force, the panel 12 does not need to worry about being separated from the cabinet 11, and the operation is convenient.

[0059] In an optional embodiment, the microorganism detector further comprises a damping mechanism 30 arranged between the cabinet 11 and the drawer body 21 and / or the panel 12. When the incubation assembly 20 approaches the closed position and / or the panel 12 is closed, the magnetic attraction mechanism 40 is used to provide a magnetic attraction force to attract the incubation assembly 20 and / or the panel 12 to the cabinet 11, and the damping mechanism 30 is used to provide a reverse damping force to smoothly close the incubation assembly 20 and / or smoothly close the panel 12, so as to reduce the speed of the incubation assembly 20 when closed and / or the panel 12 when closed relative to the cabinet 11, improve the stability of the incubation assembly 20 during the closing process and / or the panel 12 during the closing process, enhance the buffering force between the incubation assembly 20 and / or the panel 12 and the cabinet 11, avoid the incubation assembly 20 and / or the panel 12 from being bounced away due to the rebound force when colliding with the cabinet 11, make the contact between the incubation assembly 20 and / or the panel 12 and the cabinet 11 more rigorous, so as to ensure the sealing of the incubation assembly 20 when in the closed position and / or the panel 12 when closed, meet the sealing requirements of the incubation environment, and also will not affect the sample container and detection assembly in the incubation assembly 20, thereby improving the reliability and safety of the microorganism detector.

[0060] For example, when the incubation assembly 20 is close to the closed position, the incubation assembly 20 is attracted by the magnetic attraction mechanism 40, so that the incubation assembly 20 can quickly move towards the closed position; or when the incubation assembly 20 is subjected to an external force or has a high initial speed and moves towards the closed position, the incubation assembly 20 is easily bounced away due to the rebound force when colliding, and even causes damage to the incubation assembly 20 and other problems. And / or, when the panel 12 is closed, the panel 12 is attracted by the magnetic attraction mechanism 40, so that the panel 12 can quickly move towards the closed position; or when the panel 12 is subjected to an external force or has a high initial speed and moves towards the closed position, the panel 12 is easily bounced away due to the rebound force when colliding, and even causes damage to the panel 12 and other problems. Therefore, by cooperating with the damping mechanism 30, the damping force opposite to the movement direction of the incubation assembly 20 and / or the panel 12 can be generated, so that the moving speed of the incubation assembly 20 and / or the panel 12 is slowed down, thereby avoiding the incubation assembly 20 and / or the panel 12 from being bounced away due to the rebound force when colliding, making the contact between the incubation assembly 20 and / or the panel 12 and the cabinet 11 more tight, so as to ensure the sealing performance of the incubation assembly 20 in the closed position and / or the panel 12 in the closed position, meet the sealing requirements of the incubation environment, and reduce the impact on the detection assembly and other components on the incubation assembly 20 caused by the collision when the incubation assembly 20 is closed and / or the panel 12 is closed, even the displacement, thereby improving the reliability and safety of the microorganism detector.

[0061] It should be noted that when the incubation assembly 20 moves from the closed position to the open position and / or the panel 12 moves from the closed state to the open state, the damping mechanism 30 can also generate a damping force opposite to the movement direction of the incubation assembly 20 and / or the panel 12, so as to prevent the incubation assembly 20 and / or the panel 12 from moving relative to the cabinet 11 under the condition of no force, and prevent the incubation assembly 20 from being closed tightly and / or the panel 12 from being closed tightly during operation. In this way, the incubation assembly 20 and / or the panel 12 can be prevented from being always tightly attached to the cabinet 11 under the condition of no force, so as to ensure the sealing effect between the incubation assembly 20 and / or the panel 12 and the cabinet 11; and even the incubation assembly 20 and / or the panel 12 can be reset by the damping mechanism 30 during the process of carrying or transporting, so as to increase the stability of the incubation assembly 20 in the closed position and / or the panel 12 in the closed position, avoid the risk of abnormal sliding of the incubation assembly 20, prevent the carrier from being injured and the detector from being damaged, and improve the safety of the detector.

[0062] With the above technical solutions, when the incubation assembly 20 is close to the closed position and / or the panel 12 is closed, the incubation assembly 20 is quickly moved towards the closed position under the attraction force of the magnetic attraction mechanism 40, external force and / or high initial speed and / or the panel 12 is quickly moved towards the closed side under the attraction force of the magnetic attraction mechanism 40, external force and / or high initial speed, and the damping mechanism 30 generates a damping force opposite to the moving direction of the incubation assembly 20 and / or the panel 12 at this time, thereby improving the stability of the incubation assembly 20 during the closing process and / or the panel 12 during the closing process, enhancing the buffering force between the incubation assembly 20 and / or the panel 12 and the cabinet 11, slowing down the moving speed of the incubation assembly 20 and / or the panel 12, avoiding the rebound force of the incubation assembly 20 and / or the panel 12 caused by the collision, and prolonging the service life of the incubation assembly 20, the panel 12 and / or the cabinet 11. In this way, the attraction effect of the incubation assembly 20 and / or the panel 12 and the cabinet 11 is ensured, and the collision between the incubation assembly 20 and / or the panel 12 and the cabinet 11 is avoided, thereby avoiding the damage of the incubation assembly 20 and / or the panel 12 caused by the long-time collision and prolonging the service life.

[0063] In an optional embodiment, the incubation assembly 20 comprises a drawer body 21 and at least one incubation block, and the drawer body 21 is a main supporting structure of the incubation assembly 20. The drawer body 21 is movably installed in the incubation cavity, the incubation block is arranged in the drawer body 21 for accommodating the sample container, the detection assembly is connected to the incubation block, and the damping mechanism 30 is arranged between the cabinet 11 and the drawer body 21 and / or the panel 12 for enhancing the buffering force between the drawer body 21 and / or the panel 12 and the cabinet 11.

[0064] In an optional embodiment, the panel 12 is fixedly connected to the drawer body 21 for driving the incubation assembly 20 to move between the open position and the closed position under the external force. When the panel 12 is closed, the incubation assembly 20 is positioned at the closed position, and when the panel 12 is opened, the incubation assembly 20 is positioned at the open position. In specific applications, the panel 12 can be arranged in other ways, for example, one side of the panel 12 is connected to the cabinet 11 through a rotating shaft structure, and the operator or the operating robot opens the incubation cavity in a fan-shaped manner during use to facilitate the operation of the incubation assembly 20.

[0065] In an optional embodiment, as Figure 5 and Figure 6As shown, the damping mechanism 30 comprises a sliding member 32, a fixed member 31 and a damper 33, one of the sliding member 32 and the fixed member 31 is connected with the cabinet 11, the other of the sliding member 32 and the fixed member 31 is connected with the drawer body 21, the damper 33 is arranged between the sliding member 32 and the fixed member 31 and can exert a damping force on the sliding member 32, the damping force is in the opposite direction of the movement direction of the drawer body 21, for reducing the impact when the drawer body 21 approaches the closed position, avoiding the drawer body 21 being bounced away due to the rebound force when colliding with the cabinet 11, ensuring the close contact between the drawer body 21 and the cabinet 11, guaranteeing the sealing performance of the drawer body 21 and the cabinet 11 in the closed position, and effectively reducing the influence of the vibration generated when the drawer body 21 is closed on the detection components in the drawer body 21, improving the reliability when the drawer body 21 is closed in place.

[0066] For example, when the operator closes the drawer body 21, only an initial speed is needed to be given to the drawer body 21, and then the drawer body 21 can slide along the extension direction of the fixed member 31 relative to the cabinet 11 through the cooperation of the sliding member 32 and the fixed member 31, and then slowly and safely automatically slide to the closed position under the damping action of the damper 33, avoiding the drawer body 21 being bounced away due to the rebound force when colliding with the cabinet 11, and playing a role of gentle closing. At the same time, no matter how large the pushing force is, the drawer body 21 can be slowly closed, without any collision noise, and ensuring that the incubation block, sample container and detection components in the drawer body 21 are not damaged. In addition, the drawer body 21 also cannot freely slide out under the action of the damper 33, preventing the danger of accidental falling and the like.

[0067] In an optional embodiment, the damping mechanism 30 comprises an elastic member arranged between the sliding member 32 and the fixed member 31 and capable of providing a restoring force when the drawer body 21 approaches the closed position, so as to drive the drawer body 21 to move in the direction of the closed position by using the elastic energy stored in the drawer body 21 when the drawer body 21 is opened, that is, only a small force is needed to realize the automatic closing of the drawer body 21 when the drawer body 21 is closed, which is simple in structure, convenient to use and labor-saving. At the same time, the damper 33 can provide a certain buffering force during the sliding of the sliding member 32 relative to the fixed member 31 to the closed position, so that the closing of the sliding member 32 is more smooth and the noise is small.

[0068] In an optional embodiment, the damping mechanism 30 comprises but is not limited to a slide rail structure, the sliding member 32 is a movable slide rail frame of the slide rail structure, the fixed member 31 is a fixed slide rail seat of the slide rail structure, the movable slide rail frame is installed on the drawer body 21, and the fixed slide rail seat is installed on the cabinet 11.

[0069] In an alternative embodiment, the drawer body 21 has a first preset stroke and a second preset stroke, both of which are between the closed position and the open position, and the distance from the second preset stroke to the closed position is greater than the distance from the first preset stroke to the closed position. Wherein the magnetic attraction mechanism 40 releases the attraction to the drawer body 21 when the drawer body 21 is between the first preset stroke and the open position; the elastic member and the damper 33 release the action to the drawer body 21 when the drawer body 21 is between the second preset stroke and the open position.

[0070] It should be noted that the magnetic attraction mechanism 40 releases the attraction to the drawer body 21 means that the magnetic attraction force of the magnetic attraction mechanism 40 decreases by a negligible value as the position of the drawer body 21 changes, and the action stroke of the magnetic attraction mechanism 40 in the present application is short, and the magnetic attraction force of the magnetic attraction mechanism 40 gradually decreases after the drawer body 21 exceeds the first preset stroke, and can even be negligible. When the drawer body 21 moves from the closed position to the side of the open position, the drawer body 21 drives the movable slide rail frame to move relative to the fixed slide rail seat and move away from the closed position, at this time the damper 33 can generate a damping force opposite to the movement direction of the movable slide rail frame, and the elastic member will also generate a restoring force opposite to the movement direction of the movable slide rail frame, that is, the drawer body 21 needs to overcome the damping force of the damper 33, the restoring force of the elastic member and the magnetic attraction force of the magnetic attraction mechanism 40, in order to move the drawer body 21 from the closed position to the open position. Therefore, the setting of the damping mechanism 30 of the present application can also prevent the drawer body 21 from being not firmly closed during sliding due to the lack of effective locking mechanism, so as to ensure the sealing performance of the drawer body 21 in the closed position.

[0071] When the drawer body 21 is closed, the drawer body 21 drives the movable slide rail frame to move relative to the fixed slide rail seat and move towards the side close to the closing position. When the drawer body 21 moves to the second preset stroke, the damper 33 can generate a damping force opposite to the movement direction of the movable slide rail frame, and the elastic member releases the elastic energy stored by the drawer body 21 when the drawer body 21 is opened to provide a restoring force for the drawer body 21 to slide from the second preset stroke to the closing position, and the restoring force decreases as the distance between the drawer body 21 and the closing position decreases. When the drawer body 21 moves to the first preset stroke, the magnetic attraction mechanism 40 provides a magnetic attraction force to the drawer body 21, so that the drawer body 21 can move towards the closing position under the action of the magnetic attraction force. That is, when the drawer body 21 is close to the closing position, the drawer body 21 is subjected to the restoring force of the elastic member in the same direction as the movement direction and the magnetic attraction force of the magnetic attraction mechanism 40, and at the same time, the drawer body 21 is also subjected to the damping force of the damper 33 opposite to the movement direction, so that the drawer body 21 can be safely and automatically and slowly slid to the closing position under the joint action of the magnetic attraction force, the restoring force and the damping force, avoiding the rebound force caused by the collision between the drawer body 21 and the cabinet 11.

[0072] In an optional embodiment, the damping mechanism 30 is arranged at least one side of the drawer body 21 and extends along the movement direction of the drawer body 21, so that the damping mechanism 30 can provide a certain buffering force during the closing of the drawer body 21, making the closing of the drawer body 21 more smooth and the noise smaller. In addition, the damping mechanism 30 can also provide a guiding sliding function, so that the sliding member 32 always slides along the extension direction of the fixed member 31, and ensures that the sliding member 32 does not separate from the fixed member 31, improving the stability of the drawer body 21 during sliding.

[0073] For example, the number of damping mechanisms 30 is one and arranged at the upper end surface of the drawer body 21, and the two sides of the drawer body 21 are connected with the cabinet 11 through the guide slide rail, so that the drawer body 21 can move relative to the cabinet 11 along the guide direction of the damping mechanism 30 and the guide slide rail. The guide slide rail can be a common slide rail or a damping slide rail, which is not limited in the application.

[0074] For example, the number of damping mechanisms 30 is two, and the two damping mechanisms 30 are arranged at the two sides of the drawer body 21, so that the drawer body 21 can move relative to the cabinet 11 along the guide direction of the damping mechanism 30, providing support, damping and guiding functions for the movement of the drawer body 21.

[0075] For example, the number of damping mechanisms 30 is three or four, two of which are arranged on both sides of the drawer body 21, and the other one or two are connected to the upper end face and / or the lower end face of the damping mechanism 30, providing support, damping and guiding for the movement of the drawer body 21.

[0076] It should be noted that the number of damping mechanisms 30 can be set according to the weight of the drawer body 21, and the installation position of the damping mechanism 30 can be arranged on the same side or different sides of the drawer body 21, which is not limited by the present application.

[0077] In an optional embodiment, the direction of the restoring force generated by the elastic member is the same as the direction of the magnetic attraction force generated by the magnetic attraction mechanism 40, so that the drawer body 21 can slide to the closed position under the joint action of the elastic member and the magnetic attraction mechanism 40 along the guiding direction of the damping mechanism 30.

[0078] In an optional embodiment, the magnetic attraction force generated by the magnetic attraction mechanism 40 decreases as the distance between the drawer body 21 and the closed position increases within the first preset stroke, and the restoring force of the elastic member increases as the distance between the drawer body 21 and the closed position increases within the second preset stroke, and when the drawer body 21 is in the second preset stroke, the restoring force of the elastic member and the damping force of the damper 33 on the drawer body 21 become small or even disappear, so that the drawer body 21 can be kept between the second preset stroke and the open position.

[0079] In an optional embodiment, when the drawer body 21 is not subjected to external force within the first preset stroke, the damping force generated by the damper 33 is positively correlated with the combined force of the magnetic attraction force generated by the magnetic attraction mechanism 40 and the restoring force generated by the elastic member, so that the damping force generated by the damper 33 can dynamically respond to the combined force of the magnetic attraction mechanism 40 and the elastic member, to ensure that the drawer body 21 can slowly move towards the closed position under the action of the combined force of the magnetic attraction mechanism 40 and the elastic member and the damping force of the damper 33, so that the closing of the drawer body 21 is smoother and the noise is smaller. Wherein, the damper 33 provides a buffering force for the closing or opening of the drawer body 21, so that the drawer body 21 can move slowly, avoid being bounced away due to the collision with the cabinet 11 or the rebound force generated by the collision, and also can prevent the drawer body 21 from being not firmly closed during the sliding process due to the lack of effective locking mechanism, so as to ensure the sealing performance of the drawer body 21 in the closed position.

[0080] It should be noted that the first preset stroke refers to the distance between the closed position and the first preset stroke of the drawer body 21.

[0081] For example, the greater the combined force of the magnetic attraction mechanism 40 and the elastic member and / or the closing speed of the drawer body 21, the greater the damping force generated by the damper 33; conversely, the smaller the combined force of the magnetic attraction mechanism 40 and the elastic member and / or the closing speed of the drawer body 21, the smaller the damping force generated by the damper 33. When the drawer body 21 is not subjected to an external force within the first preset stroke, the combined force of the magnetic attraction force generated by the magnetic attraction mechanism 40 and the restoring force generated by the elastic member is not less than the damping force generated by the damper 33.

[0082] In an optional embodiment, when the drawer body 21 is not subjected to an external force between the first preset stroke and the second preset stroke, the damping force generated by the damper 33 is positively correlated with the size of the restoring force generated by the elastic member, so as to ensure that the drawer body 21 can slowly move towards the closed position under the action of the elastic member at the second preset stroke. The distance from the second preset stroke to the closed position is greater than the distance from the first preset stroke to the closed position.

[0083] For example, when the drawer body 21 is not subjected to an external force between the first preset stroke and the second preset stroke, the restoring force generated by the elastic member decreases as the distance from the drawer body 21 to the closed position decreases, and the resistance of the drawer body 21 decreases accordingly, that is, the damping force generated by the damper 33 decreases.

[0084] In an optional embodiment, when the drawer body 21 is subjected to an external force between the first preset stroke and the second preset stroke, the damping force generated by the damper 33 is positively correlated with the combined force of the restoring force generated by the elastic member and the external force, so as to ensure that the drawer body 21 can slowly move towards the closed position under the action of the elastic member at the second preset stroke. The distance from the second preset stroke to the closed position is greater than the distance from the first preset stroke to the closed position.

[0085] For example, when the drawer body 21 is subjected to an external force between the first preset stroke and the second preset stroke, the drawer body 21 moves towards the closed position side under the combined action of the restoring force and the external force, and the resistance thereof decreases as the combined force of the restoring force and the external force decreases, or increases as the combined force of the restoring force and the external force increases, that is, the damping force generated by the damper 33 is related to the combined force of the restoring force and the external force.

[0086] In an optional embodiment, when the drawer body 21 moves at an initial speed not less than zero between the first preset stroke and the second preset stroke, the damping force generated by the damper 33 is positively correlated with the size of the initial speed.

[0087] For example, when the drawer body 21 is between the first preset stroke and the second preset stroke, the drawer body 21 moves towards one side of the closed position at an initial speed of not less than zero. Wherein, the faster the initial speed of the drawer body 21, the greater the resistance the drawer body 21 receives, that is, the greater the damping force generated by the damper 33; on the contrary, the slower the initial speed of the drawer body 21, the smaller the resistance the drawer body 21 receives, that is, the smaller the damping force generated by the damper 33.

[0088] In an optional embodiment, the sliding member 32 is provided with a first coupling part 321, the damper 33 is provided with a second coupling part 331, and the damper 33 is arranged on the fixed member 31. The first coupling part 321 can be coupled with the second coupling part 331 within the second preset stroke to reduce the moving speed of the sliding member 32, so that the drawer body 21 can be closed gently or the drawer body 21 can be prevented from being opened automatically within the second preset stroke; or the first coupling part 321 can be separated from the second coupling part 331 outside the second preset stroke to remove the resistance of the damper 33 to the sliding member 32, so that the drawer body 21 can be opened more smoothly.

[0089] It should be noted that the within the second preset stroke refers to the drawer body 21 between the closed position and the second preset stroke, and the outside the second preset stroke refers to the drawer body 21 between the second preset stroke and the open position.

[0090] For example, the first coupling part 321 is a connecting groove arranged on the sliding member 32, and the second coupling part 331 is a connecting protrusion arranged on the damper 33. When the sliding member 32 moves from the open position to the second preset stroke, the connecting protrusion is clamped with the connecting groove, so that the damper 33 can generate a damping force opposite to the moving direction of the sliding member 32 within the second preset stroke to reduce the moving speed of the sliding member 32, so that the drawer body 21 can be closed gently. Or, when the sliding member 32 moves from the closed position to the second preset stroke, the sliding member 32 is connected with the damper 33 through the clamping of the connecting protrusion and the connecting groove, so that the damper 33 can generate a damping force opposite to the moving direction of the sliding member 32 to prevent the drawer body 21 from being opened automatically. When the sliding member 32 moves from the second preset stroke to the open position, the connecting protrusion is separated from the connecting groove, that is, the damper 33 will not generate a damping force to the sliding member 32, so that the opening force of the drawer body 21 is reduced to the minimum, and the drawer body 21 can be kept between the second preset stroke and the open position.

[0091] In an optional embodiment, the damper 33 and the elastic member will not generate corresponding damping force and restoring force between the second preset stroke and the open position, so as to ensure that the drawer body 21 can be kept in the open position, and facilitate the putting and taking of the sample container.

[0092] In an alternative embodiment, the damping mechanism 30 comprises a connecting member and a damper 33, the panel 12 is rotatably connected to the cabinet 11 through the connecting member, and the damper 33 is arranged in the connecting member, so that when the panel 12 rotates towards the closed position, the damper 33 can generate a damping force opposite to the direction of the movement of the panel 12, so as to reduce the speed of the panel 12 when closing, avoid the panel 12 from colliding with the cabinet 11, or the panel 12 from being bounced away when colliding, and also prevent the panel 12 from being not tightly closed due to lack of effective locking mechanism during rotation, so as to ensure the sealing performance of the panel 12 when closing.

[0093] In an alternative embodiment, the connecting member comprises a rotating shaft, a first hinge and a second hinge, the first hinge is connected to the panel 12, the second hinge is connected to the cabinet 11, and the rotating shaft is arranged between the first hinge and the second hinge, so that the first hinge and the second hinge are rotatably connected together. In this embodiment, the damper 33 is arranged between the first hinge and the second hinge, so as to generate a damping force opposite to the direction of the movement of the panel 12, provide a buffering force for the rotation of the panel 12, and also prevent the panel 12 from being not tightly closed due to lack of effective locking mechanism during rotation, so as to further improve the sealing performance of the panel 12 when closing.

[0098] For example, the first magnetic attraction member is at least one magnet arranged on the cabinet 11, and the second magnetic attraction member is a magnet or a magnetic metal member arranged on the drawer body 21 and / or the panel 12, so that the magnet or the magnetic metal member can be adsorbed on the at least one magnet.
