However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Through this design, the cross-section of the space of the through hole 30 for accommodating the chemical reagent gradually increases during the process of the chemical reagent falling along the through hole 30, thereby preventing the chemical reagent from adhering to the inner wall. The top of the cylinder 26 is fixedly connected to the support frame 13, and the top of the support frame 13 is fixedly connected to the collection bucket 10, and the collection bucket 10 is connected to the cylinder 26.

After the screw cap 11 is unscrewed from the inside of the collecting bucket 10 by the handle 14, various chemical reagents can be conveniently poured into the inside of the collecting bucket 10, and then flow into the inside of the liquid bottle 1 through the cylinder 26. During the process, the contact between the liquid bottle 1 and the outside world is only connected by the narrow through hole 30, thereby greatly reducing the degree of air exchange between the inside of the liquid bottle 1 and the outside world, thereby reducing the degree of reaction between the internal reagents and the air. In addition, the sealing cover 15 can be removed to inject gas into the inside of the collecting bucket 10 through the air pipe 12 to meet the experimental needs. Through this design, the narrow through hole 30 replaces the normal bottle mouth to communicate with the outside world, reduces the rate at which the chemical reagents react with the air, thereby reducing the impact on the data in the entire reaction process, and improving the accuracy of the data.
