The utility model discloses a theory of operation introduces:
when solution weighing is carried out, the multi-volume automatic measuring cylinder is placed to a proper horizontal position or is weighed by hand. There may be two weighing modes: one method is that a funnel is arranged at an opening of a required measuring cylinder volume to pour the solution, redundant liquid flows into a cup body along a return pipe, an observation hole and the other measuring cylinder opening which does not need to pour the solution are blocked by a blocking object such as a rubber plug or a cover, and finally the measuring cylinder which needs to be poured is poured along the other side of the return pipe to obtain the solution of the measuring range of the measuring cylinder; after pouring, the large and small measuring tube openings and the observation holes are blocked by rubber plugs. The second is to block up the rubber stopper for the size nozzle, install supporting funnel and empty the solution from the funnel on observing the hole, empty the back that finishes, remove the funnel, block up size nozzle and observation hole with three rubber stopper lid, then overturn whole device many times to solution in being full of the size graduated flask, then put and stew and wait to unnecessary solution along the back in the return conduit, take down the rubber stopper of the graduated flask that needs to empty, then empty along the opposite side of return conduit, obtain the solution of the corresponding range of graduated flask, it blocks up the graduated flask of empting with the rubber stopper after having emptyd.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Example 1: as shown in fig. 1-5, the multifunctional automatic measuring cup is placed on a horizontal table, the funnel is installed at the mouth of the measuring cylinder required to be weighed according to the requirement, then the solution required to be weighed is poured into the funnel, and the redundant solution flows back into the cup body 1 along the return pipe 3 for secondary use or storage. The viewing hole 4 is now blocked with a rubber stopper 8 and the weighed solution is then poured along the other side of the return tube 3.
In practical situations, the measuring cup is made of opaque materials, the opaque materials are polytetrafluoroethylene materials, the polytetrafluoroethylene materials are resistant to corrosion of hydrofluoric acid solution, resistant to scalding, resistant to falling and not prone to cracking, solutions which are prone to decomposition under visible light include AgNO3, KMnO4, H2O2, chlorine water, bromine water, iodine water and the like, and when the liquids are measured, the opaque materials are very beneficial.
Example 2: the rubber stopper is used for blocking the 2 mouths of the large and small measuring cylinders as shown in figures 1-5, the solution is poured from the funnel on the observation hole 4 by installing the matched funnel, after pouring is finished, the funnel is removed, the 2 mouths of the large and small measuring cylinders and the observation hole 4 are blocked by using the three rubber stopper covers 8, then the whole device is overturned for multiple times until the solution is filled in the large and small measuring cylinders 2, then the device is put in a standing mode and waits for the redundant solution to be poured along the return pipe 3, the rubber stopper of the measuring cylinder needing to be poured is taken down, then the measuring cylinder is poured along the other side of the return pipe 3, the poured measuring cylinder is blocked by the rubber stopper after pouring is finished, and meanwhile, the length of the large and small measuring cylinders is slightly longer, so that the pouring is more convenient.
In practical situations, when some liquid solution is measured, for example, hydrofluoric acid cannot be used for the glass return tube 3, the plastic return tube 3 or other materials should be used instead to prevent the corrosion of the return tube 3, and the scale 7 on the cup body 1 can also measure the size of other objects.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention.
