[0002] With the continuous advancement of science and technology, a large amount of waste liquid will be generated when conducting experiments in the laboratory. In order to treat the waste liquid generated by the experiment, it is necessary to collect the waste liquid. The whole process requires the use of a waste liquid collection device used in analytical chemistry laboratories. The waste liquid collection device used in analytical chemistry laboratories is a device that collects the waste liquid generated by the experiment during the nano-experiment. The waste liquid collection device used in analytical chemistry laboratories is mainly composed of a shell component, a connection component, a power component and a collection component. The waste liquid collection device used in analytical chemistry laboratories has the advantages of fast collection speed and good collection effect.

[0003] Common waste liquid collection devices used in analytical chemistry laboratories generally have the following defects during use: First, during the use of the waste liquid collection device commonly used in analytical chemistry laboratories, during the collection process, the waste liquid generated by the experiment is directly introduced into the collection dish or collection bottle through a catheter. Since the collection dish or collection bottle is set without a cover, the waste liquid generated by the experiment will contact with the air, which is not conducive to the collection of the waste liquid generated by the experiment. Moreover, after the collection is completed, the collection of the waste liquid cannot be automatically stopped and needs to be stopped manually, which is not conducive to the collection process; Second: In the process of using the waste liquid collection device commonly used in analytical chemistry laboratories, in order to facilitate the treatment and collection of experimental waste liquid, it is generally necessary to treat the waste liquid generated by the experiment, generally by electrolysis. In order to better treat it, it is necessary to keep power supply throughout the process so that electrolysis can proceed. The whole process consumes a lot of resources and requires manual assistance; Third: During the use of the waste liquid collection device commonly used in analytical chemistry laboratories, after the collection is completed, the experimenters cannot understand the collection and treatment status of the waste liquid. Special equipment is needed to detect the waste liquid. The operation process is relatively complicated, which is not conducive to the collection of waste liquid; To sum up: the common waste liquid collection device used in analytical chemistry laboratories has the following defects during use: since the collection dish or collection bottle is set without a cover, the waste liquid generated by the experiment will come into contact with the air, which is not conducive to the collection of the waste liquid generated by the experiment, and after the collection is completed, the collection of the waste liquid cannot be stopped automatically, and needs to be stopped manually, and power needs to be supplied throughout the whole process to facilitate electrolysis.
