Description

Technical Field

[0001] The utility model relates to the technical field of diluters, in particular to a reagent diluting device for laboratories. Background Art

[0002] The diluter is a professional device used in the laboratory to accurately dilute various solutions. It can automatically dilute samples or reagents according to the preset ratio. Its working principle is usually to use a high-precision pump device to absorb a certain amount of stock solution, and then accurately mix it with a set amount of diluent. In scientific research, the diluter plays a key role in processing crop samples, detecting microorganisms, and in various fields of inspection and analysis, environmental monitoring, etc.

[0003] In the traditional diluter operation process, the method of injecting a large amount of diluent into the original liquid has significant disadvantages. Usually, the original liquid is only transported to the diluent container by a pump, and then the mixing is completed by the diffusion of the liquid itself. This simple and extensive method will lead to low efficiency. When faced with the need to process a large amount of diluent, it is difficult for the original liquid to be fully and evenly dispersed in it, resulting in high or low local concentrations, which seriously interferes with the dilution quality. In the batch sample dilution link of medical testing, uneven concentration may lead to misjudgment of disease indicators. Moreover, due to the slow mixing process, each batch dilution operation takes a lot of time. Utility Model Content

[0004] The utility model aims to provide a laboratory reagent dilution device, in which a pipette is connected to a liquid taking terminal tube through a connecting tube, a connecting ring and a mixing blade are rotatably installed on the outer side of the connecting tube, and when discharging liquid, the liquid flow pushes the paddle on the fixed plate, driving the fixed plate, the slip ring and the connecting ring to rotate, thereby causing the mixing blade to rotate in the diluent, thereby improving the dilution quality of the stock solution and the operating efficiency of batch dilution, and can effectively solve the problems in the background technology.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a laboratory reagent dilution device, including a main box 1, a multi-axis slide mechanism 2 is fixedly installed on the main box 1, a pipetting mechanism 3 is movably installed on one side of the multi-axis slide mechanism 2, a plurality of pipettes 4 are movably installed at the lower end of the pipetting mechanism 3, one end of the pipette 4 is fixedly connected to a liquid collection terminal tube 5 through a connecting tube 6, a connecting ring 7 is movably installed on the outer side of the connecting tube 6, a plurality of mixing blades 8 are fixedly installed on the outer side of the connecting ring 7, a plurality of slip rings 9 are fixedly installed on the inner side of the mixing blades 8, and a fixing plate 10 is fixedly installed on the inner side of the slip ring 9.

[0022] like Figure 3-Figure 4 As shown, two first rotation grooves 11 are provided on the outer side of the connecting tube 6, a second rotation groove 12 is provided on the inner side of the first rotation groove 11, and the inner side of the second rotation groove 12 is connected to the inner cavity of the connecting tube 6, and the outer side of the second rotation groove 12 is connected to the inner cavity of the first rotation groove 11. The setting of the first rotation groove 11 can provide a rotation guide for the slip ring 9, and the opening of the second rotation groove 12 enables the inner side of the fixing plate 10 to pass through the second rotation groove 12 and extend into the connecting tube 6, and V-shaped sealing grooves 13 are provided on both sides of the inner side of the second rotation groove 12.

[0023] like Figure 3As shown, an inner tube 14 is fixedly connected between the pipette 4 and the liquid collection terminal tube 5 and is located in the connecting tube 6. A flow guide cover 15 is fixedly installed on the side of the inner tube 14 close to the pipette 4. A plurality of medium channels 16 are also opened on both sides of the inner tube 14. The arrangement of the inner tube 14 and the flow guide cover 15 allows part of the liquid to pass through the channel between the connecting tube 6 and the inner tube 14 when discharging the liquid, thereby providing power conditions for the rotation of the connecting ring 7.

[0024] like Figure 3-Figure 5 As shown, the fixing plate 10 passes through the second rotating groove 12 and extends into the connecting tube 6 and is fixedly installed with a plurality of paddles 18. A plurality of paddles 18 are arranged on the inner side of the fixing plate 10, so that the liquid entering between the connecting tube 6 and the inner tube 14 can push the paddles 18 and drive the fixing plate 10 to rotate. Two sealing patches 17 are fixedly installed on both sides of the fixing plate 10, and the sealing patches 17 are arranged in a ring shape along the side contour of the fixing plate 10. One side of the sealing patch 17 also extends into the V-shaped sealing groove 13 and fits on the inner side of the V-shaped sealing groove 13. The sealing patches 17 arranged on both sides of the fixing plate 10 cooperate with the V-shaped sealing grooves 13 opened on both sides of the second rotating groove 12, and can be used to seal the gap between the fixing plate 10 and the second rotating groove 12 without affecting the rotation of the fixing plate 10.

[0025] It should be noted that the utility model is a laboratory reagent dilution device. When the device starts to discharge liquid, the original liquid flows from the pipette 4 to the liquid collection terminal tube 5 through the connecting tube 6. In this process, the guide cover 15 on the side of the inner tube 14 close to the pipette 4 guides part of the liquid into the channel between the connecting tube 6 and the inner tube 14. The flowing liquid impacts the paddle 18 on the inner side of the fixing plate 10. The liquid between the connecting tube 6 and the inner tube 14 impacts the paddle 18 and enters the liquid collection terminal tube 5 through a plurality of medium channels 16 near the liquid collection terminal tube 5 and is discharged into the diluent. Therefore, after the paddle 18 is pushed by the liquid, it carries The movable stator 10 starts to rotate. Since the stator 10 is fixedly connected to the slip ring 9, and the first rotation groove 11 provides a rotation guide for the slip ring 9, the slip ring 9 rotates together with the stator 10, and the slip ring 9 is closely connected to the connecting ring 7, and a plurality of mixing blades 8 are fixedly installed on the outside of the connecting ring 7. Therefore, the rotation of the slip ring 9 drives the connecting ring 7 to rotate, and then the mixing blades 8 rotate at a high speed in the diluent. Therefore, the rotation of the mixing blades 8 quickly disperses the stock solution to every corner. In this way, the stock solution and the diluent are fully mixed, avoiding the problem of uneven local concentration and effectively improving the dilution quality.
