[0041] like Figures 1 to 8As shown, the present application provides a reagent storage device for storing a reagent rack 1 carrying a plurality of reagent bottles, and the reagent storage device comprises: a storage bin 10 and a bin cover 20. The storage bin 10 stores the reagent rack 1 inside, and the top wall 11 of the storage bin 10 is provided with at least a first through hole 12 and a second through hole 13 at intervals, a portion of the plurality of reagent bottles corresponds to the first through hole 12, and a portion of the plurality of reagent bottles corresponds to the second through hole 13. The bin cover 20 is provided on the top wall 11, and the bin cover 20 is provided with at least a first hole group and a second hole group at intervals, and the first hole group includes a first hole group and a second hole group along a first reference line L1 (at Figure 4 The second hole group includes a plurality of third via holes 21 arranged at intervals along the second reference line L2 (in Figure 4 The bin cover 20 is movable on the top wall 11 and has an open position and a closed position. When the bin cover 20 is in the open position, the plurality of third through holes 21 correspond to the first through hole 12 and the plurality of fourth through holes 22 correspond to the second through hole 13; when the bin cover 20 covers the first through hole 12 and the second through hole 13, the bin cover 20 is in the closed position.

[0042] By applying the technical solution of this embodiment, when the bin cover 20 is in the open position, the plurality of third through holes 21 correspond to the first through hole 12 and the plurality of fourth through holes 22 correspond to the second through hole 13. During the sampling process of the sample analyzer, the sampling needle can pass through the third through hole 21 and the first through hole 12 to enter a part of the plurality of reagent bottles for sampling, or the sampling needle can pass through the fourth through hole 22 and the second through hole 13 to enter a part of the plurality of reagent bottles for sampling, so as to ensure that the sampling needle can accurately absorb the reagent after passing through. When the bin cover 20 covers the first through hole 12 and the second through hole 13, the bin cover 20 is in the closed position, so as to prevent the heat loss inside the storage bin 10 and achieve the heat preservation effect. Among them, since the plurality of third vias 21 are arranged at intervals along the first reference line L1, and the plurality of fourth vias 22 are arranged alternately and staggered along the second reference line L2, the user can intuitively view the third vias 21 corresponding to the reagent bottles inside the storage bin 10 and the fourth vias 22 corresponding to the reagent bottles inside the storage bin 10, and then directly identify the type of reagent bottle corresponding to the third via 21 and the type of reagent bottle corresponding to the fourth via 22, and easily identify the storage positions of different types of reagent racks, which is conducive to storing the right reagent racks and improving the user experience. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that it is not easy to identify the storage positions of different types of reagent racks.

[0043] It should be noted that the above-mentioned “first reference line L1” and “second reference line L2” are both straight lines. Of course, in an embodiment not shown in the figure, the first reference line and the second reference line can both be curves.

[0044] In this embodiment, the storage bin 10 includes a bin body with an opening, the top wall 11 and the bin body are separate structures, the top wall 11 is connected to the opening by fasteners, or the top wall 11 and the bin body are an integrally formed structure.

[0045] like Figures 1 to 8 As shown, there are multiple first vias 12, and the multiple first vias 12 are arranged at intervals along a third reference line parallel to the first reference line L1, and there are multiple second vias 13, and the multiple second vias 13 are arranged alternately and staggered along a fourth reference line parallel to the second reference line L2. When the bin cover 20 is in the open position, the multiple third vias 21 correspond to the multiple first vias 12 one by one, and the multiple fourth vias 22 correspond to the multiple second vias 13 one by one. The sampling needle can pass through the one-to-one corresponding third vias 21 and first vias 12 to enter the multiple reagent bottles for sampling, and the user can directly identify the same type of reagent bottles inside the storage bin 10 corresponding to the multiple third vias 21. When the bin cover 20 covers all the first vias 12 and all the second vias 13, the bin cover 20 is in the closed position, which can effectively prevent the heat loss inside the storage bin 10 and achieve a better insulation effect.

[0046] Specifically, the bottle openings of a part of the multiple reagent bottles on the reagent rack 1 correspond one-to-one to the multiple first through holes 12 , and the bottle openings of a part of the multiple reagent bottles on the reagent rack 1 correspond one-to-one to the multiple second through holes 13 .

[0047] Of course, in an embodiment not shown in the figure, there is one first via hole and one second via hole, the plurality of third via holes each corresponds to one first via hole, and the plurality of fourth via holes each corresponds to one second via hole.

[0048] like Figures 4 to 7 As shown, in order to facilitate the sampling needle to pass through the third via hole 21 and the first via hole 12, the diameter of the third via hole 21 is larger than the diameter of the first via hole 12. In order to facilitate the sampling needle to pass through the fourth via hole 22 and the second via hole 13, the diameter of the fourth via hole 22 is larger than the diameter of the second via hole 13.

[0049] Of course, in an embodiment not shown in the drawings, the diameter of the third via hole 21 is equal to the diameter of the first via hole 12 , and the diameter of the fourth via hole 22 is equal to the diameter of the second via hole 13 .

[0050] like Figures 4 to 8 As shown, in order to facilitate the storage of different types of reagent racks inside the storage bin 10, the second reference line L2 is parallel to the first reference line L1.

[0051] Of course, in an embodiment not shown in the figure, the second reference line L2 is perpendicular to the first reference line L1.

[0052] like Figures 4 to 7As shown, the reagent storage device also includes a first insulation layer 31 disposed on the side of the compartment cover 20 facing the top wall 11, and the first insulation layer 31 is provided with a first avoidance hole 311 corresponding to the first through hole 12 and a second avoidance hole 312 corresponding to the second through hole 13. When the sampling needle passes through the first through hole 12, the provision of the first avoidance hole 311 facilitates the sampling needle to pass through the first insulation layer 31. Similarly, when the sampling needle passes through the second through hole 13, the provision of the second avoidance hole 312 facilitates the sampling needle to pass through the first insulation layer 31.

[0053] When the bin cover 20 covers the first through hole 12 and the second through hole 13, the first thermal insulation layer 31 covers the first through hole 12 and the second through hole 13. In this way, the first thermal insulation layer 31 can achieve a better thermal insulation effect for the storage bin 10, and can prevent the cold air in the storage bin 10 from directly contacting the bin cover 20 to cause condensation.

[0054] like Figures 4 to 7 As shown, in order to fit and fix the first thermal insulation layer 31 on the side of the bin cover 20 facing the top wall 11 , a mounting groove 23 is provided on the side of the bin cover 20 facing the top wall 11 , and the first thermal insulation layer 31 is disposed in the mounting groove 23 .

[0055] Specifically, the above-mentioned installation groove 23 is preferably a sunken groove, and there are multiple installation grooves 23 spaced apart on the side of the bin cover 20 facing the top wall 11 . There are also multiple first insulation layers 31 , and the multiple first insulation layers 31 are arranged in the multiple installation grooves 23 one by one.

[0056] like Figures 4 to 8 As shown, the reagent storage device also includes a second insulation layer 32 arranged on the side of the top wall 11 facing the bottom wall 14 of the storage bin 10, and the second insulation layer 32 is provided with a third avoidance hole 321 corresponding to the third through hole 21 and a fourth avoidance hole 322 corresponding to the fourth through hole 22. When the sampling needle passes through the third through hole 21, the setting of the third avoidance hole 321 facilitates the sampling needle to pass through the second insulation layer 32. Similarly, when the sampling needle passes through the fourth through hole 22, the setting of the fourth avoidance hole 322 facilitates the sampling needle to pass through the second insulation layer 32. In addition, on the one hand, the second insulation layer 32 can further achieve a better insulation effect for the storage bin 10, and on the other hand, it can prevent the cold air in the storage bin 10 from directly contacting the top wall 11 to cause the generation of condensed water.

[0057] like Figure 1 and Figures 5 to 9As shown, a plurality of partitions 40 are arranged at intervals on the bottom wall 14 of the storage bin 10 in a direction perpendicular to the first reference line L1, and a mounting channel 41 is formed between each two adjacent partitions 40, forming a plurality of them in total, and a plurality of reagent racks 1 are placed in the plurality of mounting channels 41 in a one-to-one correspondence, and each reagent rack 1 is slidable in the mounting channel 41. In addition to being able to separate the internal space of the storage bin 10, the plurality of partitions 40 can also limit the reagent racks to prevent the reagent racks in the mounting channels 41 from tipping over.

[0058] like Figure 1 and Figures 5 to 9 As shown, the side wall of the reagent rack 1 is provided with a guide groove 101, and the partition 40 is provided with a guide wheel 42 that slidably cooperates with the guide groove 101. In this way, the guide groove 101 and the guide wheel 42 slidably cooperate to facilitate each reagent rack 1 to slide smoothly in the installation channel 41 where it is located.

[0059] like Figure 1 , Figures 5 to 9 As shown, one of the plurality of installation channels 41 corresponding to the first through hole 12 is the first installation channel, one of the plurality of installation channels 41 corresponding to the second through hole 13 is the second installation channel, one of the plurality of reagent racks 1 that can be placed in the first installation channel is the first reagent rack, and one of the plurality of reagent racks 1 that can be placed in the second installation channel is the second reagent rack. The bottom wall 14 is provided with a first blocking member 141 and a second blocking member 142 at intervals, the first blocking member 141 is located at the entrance of the first installation channel to block the second reagent rack from being placed in the first installation channel, the second blocking member 142 is located at the entrance of the second installation channel to block the first reagent rack from being placed in the second installation channel, the first reagent rack is provided with a first avoidance groove 102 for avoiding the first blocking member 141, and the second reagent rack is provided with a second avoidance groove 103 for avoiding the second blocking member 142. In this way, only the first reagent rack can be stored in the first installation channel, and the second reagent rack cannot be stored in the first installation channel. Similarly, only the second reagent rack can be stored in the second installation channel, and the first reagent rack cannot be stored in the second installation channel. It is convenient for users to easily identify the storage locations of different types of reagent racks and prevent reagent racks from being misplaced, thereby further improving the user experience.

[0060] Specifically, the first blocking member 141 is located on the left side of the first installation channel, and the second blocking member 142 is located on the right side of the second installation channel.

[0061] like Figures 1 to 3 As shown, in order to facilitate the movement of the compartment cover 20 on the top wall 11, the reagent storage device further includes a driving member 50 disposed on the storage compartment 10, and the driving member 50 drives the compartment cover 20 to move on the top wall 11. In this way, under the driving action of the driving member 50, the compartment cover 20 is convenient to move to the open position or to the closed position.

[0062] like Figures 1 to 3 As shown, the driving member 50 includes a motor 51 and an eccentric shaft 52 connected to the motor shaft of the motor 51. A limiting long hole 24 is provided on the bin cover 20 for the eccentric shaft 52 to pass through. The overall extension direction of the limiting long hole 24 is parallel to the first reference line L1. The motor shaft rotates to drive the eccentric shaft 52 to rotate. When the eccentric shaft 52 rotates, it moves in the limiting long hole 24 and drives the bin cover 20 to move, so as to realize the movement of the bin cover 20 between the open position and the closed position.

[0063] like Figures 1 to 3 As shown, a rolling member 60 is disposed between the top wall 11 and the bin cover 20. When the eccentric shaft 52 drives the bin cover 20 to move, the arrangement of the rolling member 60 can reduce the contact area between the top wall 11 and the bin cover 20, thereby reducing friction, so that the bin cover 20 is smoothly driven by the eccentric shaft 52. The rolling member 60 includes a roller.

[0064] It should be noted that the “plurality” appearing in this application refers to a number greater than or equal to two.

[0065] The present application also provides a sample analyzer, which includes a reagent storage device, and the reagent storage device is the above-mentioned reagent storage device. Since the above-mentioned reagent storage device can solve the problem in the related art that it is not easy to identify the storage positions of different types of reagent racks, the sample analyzer including the reagent storage device can solve the same technical problem. The sample analyzer also includes a reagent processing device and a detection device.

[0066] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0067] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0068] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0069] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
