[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2 As shown, this biochemical reagent preparation device includes a frame, a drive component 3, a drive component 4, a lifting plate 5, an upper feed cylinder 6, a lower feed cylinder 7, and a positioning component. The lifting plate 5 is connected to the upper part of the frame. The drive component 3 is located between the lifting plate 5 and the frame and can drive the lifting plate 5 to move up and down. The upper feed cylinder 6 is fixed to one end of the lifting plate 5. The side of the upper feed cylinder 6 has an inlet pipe 6a and an inlet pipe 6b communicating with its inner cavity. The drive component 4 is connected to the lifting plate 5. The upper feed cylinder 6 also has a stirring component and is connected to the drive component 4. The lower end of the stirring component extends out of the lower part of the upper feed cylinder 6. The positioning component is connected to the frame. When the lower feed cylinder 7 moves to the positioning component, the lower feed cylinder 7 is directly below the upper feed cylinder 6.

[0025] Initially, drive component 4 moves lifting plate 5 to its highest position. At this time, both the feeding cylinder 6 and the stirring assembly are at their highest positions. Then, external force is applied to push the feeding cylinder 7 into the positioning assembly. Once the feeding cylinder 7 enters the positioning assembly, it is vertically aligned with the feeding cylinder 6. The lower end of the stirring assembly is also located above the feeding cylinder 7, ensuring that the feeding cylinder 7 is not obstructed by the stirring assembly during its entry into the positioning assembly.

[0026] In this embodiment, the bottom of the feeding cylinder 7 is equipped with casters, which enable the feeding cylinder to enter the positioning component conveniently and stably.

[0027] Once the feeding cylinder 7 is connected to the positioning component, the drive component 3 moves the lifting plate 5 downward. The lower end of the stirring component is embedded in the feeding cylinder 7, and the lower end of the feeding cylinder 6 abuts against the upper end of the feeding cylinder 7, with the two connected.

[0028] Of course, the bottom of the upper feed cylinder 6 is open and the top of the lower feed cylinder 7 is open, so as to ensure that the upper feed cylinder 6 and the lower feed cylinder 7 are connected.

[0029] Next, as the driving component 4 drives the stirring assembly to rotate continuously, the dry powder in the feeding cylinder 7 can be fully mixed with water.

[0030] The feed pipe 6a on the feeding cylinder 6 is used to inject dry powder, and the feed pipe 6b is used to inject water. Of course, the injection volume of both dry powder and water is controlled by the operator. The above injection operation is performed only after the feeding cylinder 6 and the feeding cylinder 7 are stably connected and in contact.

[0031] The frame includes a base plate 1 and a column 2, the column 2 being fixedly connected to the middle of the base plate 1, and the positioning component being located on the side of the column 2.

[0032] During the translation of the feeding cylinder 7 on the base plate, it is ensured that the feeding cylinder 7 stably enters the positioning component. The column 2 provides sufficient space for the positioning component to be set.

[0033] The positioning component includes a plate-shaped positioning plate 8, the inner end of which is fixed to the column 2, and the outer end of which has a positioning notch 8a that matches the side of the feed cylinder 7.

[0034] The positioning plate 8 is made of flexible material.

[0035] The flexible positioning plate 8 can prevent rigid contact between the feed cylinder 7 and the positioning plate 8. At the same time, the positioning notch 8a on the positioning plate 8 can accurately locate the position of the feed cylinder 7. Once the side of the feed cylinder 7 is embedded in the positioning notch 8a, it can accurately ensure that the feed cylinder 6 and the feed cylinder 7 are vertically aligned.

[0036] The lifting plate 5 has a cavity inside, and a transmission gear set is provided inside the lifting plate. The input end of the transmission gear set is connected to the driving component 2, and the output end of the transmission gear set is connected to the stirring component.

[0037] The second driving component 4 is a motor. The motor shaft is stably connected to the input end of the transmission gear set 9. Through the transmission gear set 9, the power can be stably transmitted to the stirring component, so that the stirring component can rotate continuously and stably.

[0038] The stirring assembly includes a stirring rod 10 and several blades 11 circumferentially fixed to the side of the stirring rod 10, and the output end of the aforementioned transmission gear set is connected to the stirring rod 10.

[0039] As the stirring rod 10 continues to rotate, several blades 11 rotate along with it, thereby fully mixing the dry material and water in the feeding cylinder 7.

[0040] The driving component 3 is a cylinder, the cylinder body is located inside the column 2, and the piston rod of the cylinder is fixedly connected to the lifting plate 5.

[0041] The lower part of the lifting plate 5 is also fixedly connected to a guide rod 12, and the column 2 is fixedly connected to a guide cylinder 13, with the guide rod 12 embedded in the guide cylinder 13.

[0042] The guide rod 12 and the guide cylinder 13 have a relatively large contact area, which can effectively improve the smoothness of the movement of the lifting plate 5.

[0043] The guide rod 12 and the guide cylinder 13 form a guide unit, and there are several guide units.

[0044] The arrangement of multiple guide units can further improve the movement stability of the lifting plate 5 and effectively prevent the lifting plate 5 from swinging or rotating.

[0045] A sealing ring 14 is fixedly connected to the lower end of the feeding cylinder 6.

[0046] When the feed cylinder 6 is connected to the feed cylinder 7, the sealing ring 14 is pressed tightly at the connection between the feed cylinder 6 and the feed cylinder 7, thus providing a good seal at the connection.

[0047] In this biochemical reagent preparation device, the feed cylinder can be quickly and stably separated from and connected to the feed cylinder. Once the feed cylinder and the feed cylinder are connected, dry materials and water can be easily injected into the feed cylinder through feed pipe 1 and feed pipe 2 on the feed cylinder. Therefore, the above operation process is very simple and fast. After the materials and water in the feed cylinder are fully stirred by the stirring component, the preparation process can be quickly and stably achieved. It has a high degree of automation, high operating efficiency, and high operating stability.

[0048] Meanwhile, the feeding cylinder can quickly and accurately position itself below the feeding cylinder under the positioning component, further improving stability and giving it high practical value.

[0049] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
