Description

Technical Field

[0001] The utility model relates to the technical field of liquid quantitative removal, in particular to a device for batch and quantitative removal of liquid reagents. Background Art

[0002] When filling liquids, it is usually necessary to perform quantitative filling of the fluid.

[0003] In the prior art, there is a batch and quantitative pipetting device for liquid reagents with the announcement number CN212942992U, which includes a bracket and a liquid storage bottle, and is characterized in that a batch and quantitative pipetting device is provided at the lower end of the liquid storage bottle and on the bracket. Compared with the prior art, the advantage of the present invention is that the accuracy of quantitative volume pipetting of liquid reagents is improved; however, a batch and quantitative pipetting device for liquid reagents in the prior art can only output a single amount of liquid when quantifying the liquid, which is limited by the capacity problem of the scale water divider I and the scale water divider II themselves. Therefore, the existing batch and quantitative pipetting device for liquid reagents has the problem of only being able to quantitatively perfuse and output liquid of its own specification quantity. For this reason, a batch and quantitative pipetting device for liquid reagents is proposed. Utility Model Content

As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an embodiment of the present invention provides a batch and quantitative pipetting device for liquid reagents, comprising: a shell 1, a storage shell 2 is fixedly installed in the shell 1, two first electric push rods 3 are fixedly installed on the storage shell 2, a fixing frame 4 is fixedly installed on the output ends of the two first electric push rods 3, a plurality of sliding shells 5 that are slidably matched with the storage shell 2 are fixedly installed on the fixing frame 4, a second electric push rod 6 is fixedly installed on the lower side of the plurality of sliding shells 5, a sliding frame 7 is fixedly installed on the output end of the second electric push rod 6, and a plurality of sealing components 8 for sealing the sliding shell 5 are fixedly installed on the sliding frame 7.

[0025] In this embodiment, specifically: a feed protrusion 101 is provided on the upper surface of the shell 1, a return protrusion 102 is provided on one side of the shell 1, and an inclined protrusion 103 for the reagent to flow into the return protrusion 102 is provided inside the shell 1. The setting of the inclined protrusion 103 facilitates the flow of excess reagent out of the device.

[0026] In this embodiment, specifically: a plurality of circular holes are opened on the storage shell 2, a guide groove 201 is opened between two adjacent circular holes, a rubber sealing piece 9 is fixedly installed on the bottom of the storage shell 2, and a clamping plate 10 is fixedly installed on the lower side of the storage shell 2. The opening of the guide groove 201 facilitates the flow of reagents into the circular holes.

[0027] In this embodiment, specifically: multiple sliding shells 5 are respectively slidably fitted in multiple circular holes, and the multiple circular holes are respectively communicated with the multiple sliding shells 5. A discharge protrusion 501 is provided on one side of the bottom of the multiple sliding shells 5, and a hose 11 is fixedly installed on the lower side of the multiple discharge protrusions 501. The setting of the discharge protrusion 501 facilitates the outflow of the reagent.

[0028] In this embodiment, specifically: a through hole 502 is opened inside each of the multiple sliding shells 5, and a fixing plate 12 fixedly connected to the second electric push rod 6 is fixedly installed on the lower side of the multiple sliding shells 5. The opening of the through hole 502 facilitates the outflow of the reagent from the inside of the sliding shell 5.

[0029] In this embodiment, specifically: the sealing assembly 8 includes a connecting rod 13 fixedly connected to the sliding frame 7, and a rubber block 14 fixedly connected to the connecting rod 13. The multiple rubber blocks 14 are respectively slidably fitted inside the multiple through holes 502. The installation of the connecting rod 13 facilitates the installation of the rubber blocks 14.

[0030] During operation of the present invention, when the device needs to extract reagents of different capacities in batches, the first electric push rod 3 is turned on, and the turning on of the first electric push rod 3 drives the fixed frame 4 and the plurality of sliding shells 5 to slide. When the sliding shell 5 slides, the capacity between the sliding shell 5 and the storage shell 2 changes. At this time, the reagent is introduced into the interior of the storage shell 2, and the solution inside the storage shell 2 flows into the sliding shell 5, and the excess solution flows out from the interior of the outer shell 1. At this time, the device completes the batch quantification of the reagent. The sliding distance of the sliding shell 5 is different, and the final reagent capacity obtained is different.
