Description

Technical Field

[0001] This utility model relates to the technical field of detection devices, specifically a solution dispensing device. Background Technology

[0002] Large bubble absorption tubes are devices specifically designed for collecting and detecting harmful substances in the air. They are widely used in occupational health fields such as disease prevention, environmental monitoring, occupational health, medical research, chemical industry, and mining and metallurgy. When in use, a certain amount of absorbent liquid is filled into the absorption tube, and air is drawn in by a sampling pump, so that the harmful substances in the air are captured by the absorbent liquid.

[0003] When adding solution to a large bubble absorption tube, the operator usually needs to use a pipette to transfer the solution so that there is a certain amount of solution in the large bubble absorption tube, which is convenient for the operator to carry out subsequent related operations.

[0004] Existing technologies have limitations: pipettes are slow to process liquids, their accuracy depends on the operator's skill level, and they can only aspirate from one large bubble absorption tube at a time, resulting in low efficiency. Using an automatic dispensing device would lead to increased costs and other issues. Utility Model Content

In this embodiment, the abutment plate 323 is made of elastic material.

[0050] The positioning frame 31 provides support for the installation of the fixing frame 321. The fixing frame 321 can provide a space for the large bubble absorption tube. At the same time, the spring 322 and the abutment plate 323 inside the fixing frame 321 can provide limit for large bubble absorption tubes of different sizes, further improving the overall applicability of the device.

[0051] The operating principle of a solution dispensing device is as follows: the operator first slides the sliding block 114 to a suitable position on the support rod 112, and then fixes the position of the sliding block 114 by positioning.

[0052] Place the dispenser 22 on the support plate 13 and snap the inlet tube 211 into the snap-fit ​​groove. Insert the suction tube 213 into the reagent bottle. Then, the micro pump draws the reagent into the storage tank 222. The first flow controller 223 is used to control the solvent volume.

[0053] The valve is then opened, and the reagent is rationally distributed to each connecting tube 225 through the communicating vessel 224. The second flow controller 226 is used to control the reagent volume, thus completing the synchronous dispensing of multiple large bubble absorption tubes.

[0054] The positioning frame 31 provides support for the installation of the fixing frame 321. The spring 322 and the abutment plate 323 inside the fixing frame 321 can position the large bubble absorption tubes of different sizes, improving the overall applicability of the device.
