Description

Technical Field

[0001] The invention relates to the technical field of instrument detection, in particular to a drug adding device. Background Art

[0002] The silicate continuous analyzer is an instrument used to monitor the silica content in water or steam. It is widely used in industrial fields such as power plants to ensure equipment safety and efficiency. This instrument usually uses colorimetry for measurement, relying on specific reagents to react with water samples to generate colored compounds, and then the concentration of silica is determined by measuring the absorbance of the compound at a specific wavelength. Bubbles may have a significant impact on the test results during the test, especially in the silicate determination test. Bubbles usually gather around the wells of the ELISA plate, affecting the effective contact between the liquid and the well wall, resulting in uneven reactions in the wells. For example, during the coating process, if there are bubbles, it may lead to incomplete coating, a decrease in the actual coating amount, and the final result may be weakly positive or false negative. Similarly, during sealing and sample addition, bubbles may cause non-specific binding, increase the background or weaken the effective binding of antigens and antibodies, affecting the accuracy of the experimental results.

[0003] Since existing dosing devices may generate bubbles during the dosing process, a bubble detection instrument is generally required to detect bubbles in real time during the subsequent detection process.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, reference Figures 1 to 4, which is the first embodiment of the present invention, and provides a dosing device, including, a suction mechanism 100, including a bearing assembly 101 and an operating assembly 102 disposed inside the bearing assembly 101; and a mixing mechanism 200, including a loading assembly 201 and a stirring assembly 202 disposed inside the loading assembly 201; wherein the operating assembly 102 includes a slide bar 102a, and a rotating plate 102b is disposed at the bottom of the slide bar 102a, and the rotating plate 102b and the slide bar 102a are connected to each other. 02a is rotatably connected, and relative sliding can occur between the rotating plate 102b and the sliding rod 102a. A through groove 102c is opened on the outer wall of the rotating plate 102b. There are multiple through grooves 102c, which are distributed in a circular array on the surface of the rotating plate 102b with the axis of the sliding rod 102a as the center. A slide plate 102d is arranged inside the through groove 102c, and the slide plate 102d can slide on the inner wall of the rotating plate 102b. When the slide plate 102d slides and overlaps with the through groove 102c, the through groove 102c will be closed.

[0025] Specifically, after adding medicine into the medicine adding device, the vacuum mechanism 100 can be used to evacuate the inside of the medicine adding device to form a negative pressure in the device. At the same time, in the mixing mechanism 200, the medicine is stirred by the stirring component 202. Since negative pressure is formed in the device and the medicine is stirred at the same time, the air dissolved in the medicine solution can be released at this time, thereby reducing the generation of bubbles in the subsequent detection process and improving the inspection quality.

[0026] Example 2, reference Figures 1 to 4 , which is the second embodiment of the present invention. Different from the previous embodiment, the bearing assembly 101 includes a connecting tube 101a, a trumpet-shaped tube 101b is arranged at the bottom of the connecting tube 101a, and an air vent 101c is opened on the outer wall of the trumpet-shaped tube 101b. Preferably, there are multiple air vents 101c, which are distributed in a circular array with the axis of the connecting tube 101a as the center, and a spiral groove 101d is opened on the inner wall of the connecting tube 101a. The spiral groove 101d is opened all the way to the bottom of the trumpet-shaped tube 101b. A vertical plate 101e is arranged on the top of the connecting tube 101a. There are multiple vertical plates 101e, and there are gaps between adjacent vertical plates 101e.

[0027] Furthermore, a movable plate 101f is provided on the inner wall of the connecting tube 101a, and the movable plate 101f can slide on the inner wall of the connecting tube 101a. A first elastic member 101g is provided on the top of the movable plate 101f. A cover plate 101h is provided on the top of the first elastic member 101g. The bottom of the cover plate 101h is connected to the vertical plate 101e. The first elastic member 101g is in a compressed state, pressing the movable plate 101f against the top of the connecting tube 101a.

[0028] Furthermore, the sliding rod 102a is arranged on the inner wall of the cover plate 101h, and a sliding block 102e is arranged on the side of the sliding block 102d. An operating rod 102f is arranged on the top of the sliding rod 102a, and a top plate 102g is arranged on the top of the rotating plate 102b. Pulling the operating rod 102f upwards will drive the rotating plate 102b to slide up. When the top plate 102g moves to contact with the movable plate 101f, continuing to pull the operating rod 102f and the top plate 102g will push the movable plate 101f upward to separate it from the connecting tube 101a. The sliding block 102e cooperates with the spiral groove 101d. When the operating rod 102f is pushed and pulled up and down to drive the rotating plate 102b to slide up and down, the sliding block 102e will rotate under the action of the spiral groove 101d, thereby driving the rotating plate 102b to rotate together.

[0029] Furthermore, the loading component 201 includes a loading barrel 201a arranged on the outer wall of the connecting cylinder 101a, a drug inlet pipe 201b is arranged on the side of the loading barrel 201a, the drug inlet pipe 201b is connected to the loading barrel 201a, a drug outlet pipe 201c is arranged at the bottom of the drug inlet pipe 201b, the drug outlet pipe 201c is connected to the loading barrel 201a, and the reagent solution is mixed in the loading barrel 201a.

[0030] Furthermore, the stirring assembly 202 includes a central rod 202a disposed inside the loading barrel 201a, the bottom of the central rod 202a is rotatably connected to the loading barrel 201a, and can rotate in the loading barrel 201a, the outer wall of the central rod 202a is provided with a stirring tube 202b, the outer wall of the stirring tube 202b is provided with a small hole 202c, and the interior of the stirring tube 202b is provided with a through hole 202d, and the through hole 202d makes the stirring tube 202b connected from top to bottom. When the stirring tube 202b rotates in the solution, the small hole 202c promotes the generation of bubbles in the solution, and the bubbles are discharged from the upper part of the stirring tube 202b along the through hole 202d, and the side of the stirring tube 202b is provided with a paddle member 202e, and the central rod A connecting groove 202a-1 is provided at the top of 202a, and a connecting column 202a-2 is provided inside the connecting groove 202a-1. The connecting column 202a-2 can slide in the connecting groove 202a-1, and the top of the connecting column 202a-2 is connected to the rotating plate 102b. When the operating rod 102f is pushed and pulled up and down to drive the rotating plate 102b to slide up and down, the slider 102e will rotate under the action of the spiral groove 101d, thereby driving the rotating plate 102b to rotate together. When the rotating plate 102b rotates, it will drive the connecting column 202a-2 to rotate, thereby driving the center rod 202a to rotate. The rotation of the center rod 202a will drive the stirring tube 202b and the paddle component 202e to rotate, thereby stirring the reagent solution and promoting its mixing.

[0031] Specifically, the reagent solution is added into the loading barrel 201a from the drug inlet pipe 201b, and the operating rod 102f is pulled upward to drive the rotating plate 102b to slide upward. The rotating plate 102b moves upward, and the volume between the loading barrel 201a and the rotating plate 102b at the bottom of the rotating plate 102b becomes relatively larger, and negative pressure is generated in the loading barrel 201a, which is conducive to exhausting the air in the solution. At the same time, the rotating plate 102b rotates to drive the central rod 202a to rotate, and drives the stirring tube 202b to rotate, and the small hole 202c promotes the solution. Bubbles are generated in the liquid, and the bubbles are discharged from the upper part of the stirring tube 202b along the through hole 202d, further discharging the air in the solution, effectively reducing the generation of air in subsequent detection and improving the detection quality. When the top plate 102g on the top of the rotating plate 102b contacts the movable plate 101f, the top plate 102g will push the movable plate 101f upward and separate it from the connecting tube 101a, and discharge the air in the connecting tube 101a, continuously forming a negative pressure in the loading barrel 201a to prevent the air from re-dissolving into the solvent.

[0032] Example 3, reference Figures 1 to 4 , which is the third embodiment of the present invention. Different from the previous embodiment, the paddle component 202e includes a paddle 202e-1 arranged on the outer wall of the center rod 202a, and the paddle 202e-1 can rotate on the outer wall of the center rod 202a. The outer wall of the paddle 202e-1 is provided with a clamping plate 202e-2, and the outer wall of the clamping plate 202e-2 is provided with a fan-shaped groove 202e-3. The fan-shaped groove 202e-3 is opened on the outer wall of the center rod 202a. The rotation of the paddle 202e-1 will drive the clamping plate 202e-2 to rotate in the fan-shaped groove 202e-3, and the fan-shaped groove 202e-3 will limit the rotation angle of the slurry.

[0033] Furthermore, an elastic connector 202e-4 is provided on the outer wall of the blade 202e-1, and a connecting rod 202e-5 is provided on the end of the elastic connector 202e-4 away from the blade 202e-1. The top of the connecting rod 202e-5 is connected to the rotating plate 102b through a connecting frame. Pushing and pulling the operating rod 102f up and down will drive the rotating plate 102b to slide up and down, and drive the connecting rod 202e-5 to slide up and down, thereby utilizing the elastic connector 202e-4 to drive the blade 202e-1 to rotate.

[0034] Specifically, when the operating rod 102f is pushed and pulled to drive the stirring assembly 202 in the loading bucket 201a to stir the solution, the paddle 202e-1 will also rotate. When the clamping plate 202e-2 on the outer wall of the paddle 202e-1 connects with the inner wall of the fan-shaped groove 202e-3, the paddle 202e-1 will no longer rotate and form an angle. While the center rod 202a rotates, the paddle 202e-1 will push the solution at the bottom of the loading bucket 201a upward, promote the flow of the solution in the loading bucket 201a, and enhance the stirring and mixing effect.
