[0011] Furthermore, the sealing plate is provided with a first notch for the insertion of a reagent needle; during the reagent bottle sealing operation, multiple receiving grooves are distributed along both sides of the disc body corresponding to the first notch.

[0012] Furthermore, the sealing plate is also provided with a second notch for the operator to place the reagent bottle into the plate; when performing the reagent bottle mouth sealing operation, multiple receiving slots are distributed along both sides of the plate corresponding to the second notch.

[0013] Furthermore, it also includes support frames spanning both sides of the disc body; a crossbeam is installed between the two support frames; and the drive mechanism is mounted on the crossbeam.

[0014] Furthermore, the driving mechanism includes a guide rail, a conveyor belt, a first rotating wheel, a second rotating wheel, a tensioning wheel, a conveyor plate, and a motor; the guide rail is vertically fixed on the crossbeam and positioned above the disc; the first rotating wheel and the second rotating wheel are positioned on the same side of the guide rail along its direction; the conveyor belt spans between the first rotating wheel, the second rotating wheel, and the output shaft of the motor; a tensioning wheel is positioned on the outer side of the conveyor belt; the conveyor plate is slidably mounted on the guide rail, with one side fixed to the conveyor belt between the first rotating wheel and the second rotating wheel; and a sealing plate is fixed to the bottom of the conveyor plate.

Detailed Implementation

[0022] The technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-3 As shown, a reagent compartment includes a tray 1 with multiple receiving slots 2 arranged along the circumference of the tray 1 for storing reagent bottles; a sealing plate 3 disposed above the tray 1 with multiple sealing caps 4 adapted to the reagent bottles for sealing the bottle openings; and a driving mechanism for driving the sealing plate 3 to move up and down so that the sealing caps 4 can seal or move away from the bottle openings.

[0024] This invention, through the setting of the sealing cap 4, allows the driving mechanism to move the sealing plate 3 downward when the sample analyzer completes the testing task, the reagent needle stops working, and the instrument is in standby mode. This moves the sealing cap 4 to seal the mouth of the reagent bottle, effectively preventing the evaporation of the reagent inside the bottle and improving the accuracy and efficiency of sample analysis. Furthermore, when the sample analyzer needs to run and perform sample testing tasks, the driving mechanism can move the sealing plate 3 upward, moving the sealing cap 4 away from the mouth of the reagent bottle and releasing the seal. This allows the reagent needle to complete the reagent aspiration action normally, avoiding manual opening and improving detection efficiency.

[0025] Furthermore, it also includes support frames 5 spanning both sides of the disc body 1; a crossbeam 6 is provided between the two support frames 5; and the drive mechanism is installed on the crossbeam 6.

[0026] The driving mechanism includes a guide rail 7, a conveyor belt 8, a first rotating wheel 9, a second rotating wheel 10, a tensioning wheel 11, a conveyor plate 12, and a motor 13. The guide rail 7 is vertically fixed on the crossbeam 6 and positioned above the disc body 1. The first rotating wheel 9 and the second rotating wheel 10 are positioned on the same side of the guide rail 7 along its direction. The conveyor belt 8 spans between the first rotating wheel 9, the second rotating wheel 10, and the output shaft of the motor 13. A tensioning wheel 11 is positioned on the outer side of the conveyor belt 8. The conveyor plate 12 is slidably mounted on the guide rail 8 via a slider. One side of the slider is fixed to the conveyor belt 8 between the first rotating wheel 9 and the second rotating wheel 10 via a clamping plate. The sealing plate 3 is fixed to the bottom of the conveyor plate 12. The conveyor belt 8 can drive the conveyor plate 12 to move up and down, thereby driving the sealing plate 3 and the sealing cap 4 to move up and down, thus completing the sealing or opening operation of the reagent bottle mouth.

[0027] The sealing cap 4 includes a cap body 14 for sealing the mouth of the reagent bottle; and a guide rod 15 fixedly mounted on the cap body 14; the sealing plate 3 is provided with a mounting hole 16; a cylindrical fixing cap 17 is fixed on the mounting hole 16; a guide hole 18 is provided on the top of the fixing cap 17; the top of the guide rod 15 is inserted into the bottom of the mounting hole 16 and extends to the outside of the guide hole 18 so that it can slide up and down along the mounting hole 16 and the guide hole 18; a snap-fit ​​piece 19 is provided on the guide rod 15 at the top position of the mounting hole 16 so that the guide rod 15 can be snapped into the mounting hole 16 to prevent the guide rod 15 from sliding out of the mounting hole 16; a spring 20 is sleeved on the guide rod 15 between the snap-fit ​​piece 19 and the inner side of the fixing cap 17. When the sealing plate 3 moves downward, it can carry the cap 14 towards the mouth of the reagent bottle. After the cap 14 covers the mouth of the reagent bottle, when the sealing plate 3 continues to move downward, the spring 20 can buffer the pressure of the cap 14 on the reagent bottle to prevent the reagent bottle from being crushed due to excessive pressure.

[0028] The sealing plate 3 has a first notch 21 for inserting a reagent needle. During the reagent bottle sealing operation, multiple receiving slots 2 are distributed along both sides of the disk 1 corresponding to the first notch 21; that is, the disk 1 corresponding to the first notch 21 does not have a receiving slot 2 at this time. Since the reagent needle needs to be inserted into the reagent bottle from the receiving slot 2, the first notch 21 is necessary for needle insertion. The sealing plate 3 cannot have a sealing cap 4 at the location corresponding to the needle insertion action. Therefore, when the sealing plate 3 moves the sealing cap 4 to seal the reagent bottle, the disk 1 corresponding to the first notch 21 does not have a receiving slot 2 to prevent the reagent bottle from being unable to be sealed at this location.

[0029] The sealing plate 3 also has a second notch 22 for the operator to place the reagent bottle into the tray 1. To facilitate this placement, a portion of the tray 1 extends beyond the sample analyzer. This extended portion typically has a lid, which allows the operator to easily place the opened reagent bottle into the receiving slot 2. Therefore, the sealing plate 3 corresponding to the lid needs a second notch 22 for placing the reagent bottle, preventing the sealing plate 3 from obstructing the operator's insertion into the receiving slot 2. Since a sealing cap 4 cannot be placed at the second notch 22, when the sealing plate 3 moves the sealing cap 4 to seal the reagent bottle, the tray 1 corresponding to the second notch 22 does not have a receiving slot 2, preventing the reagent bottle from being unable to be sealed at this location.

[0030] When performing the reagent bottle sealing operation, multiple accommodating slots 2 are distributed along both sides of the disk body 1 corresponding to the first notch 21 and the second notch 22.

[0031] This utility model also discloses a sample analyzer, including the reagent compartment described above.

[0032] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model shall be included within the scope of the claims of this utility model pending approval.
