In the utility model, described feeder is micro air pump or inflator.
The beneficial effects of the utility model are: the utility model is coordinated by feeder, blowdown valve and rain glass three, in experimentation, the air pressure in vial is accurately controlled, realize Cartesian diver stably to suspend in underwater, improve the direct feel of student, ensure that the reliability of experiment.
Accompanying drawing explanation
Fig. 1 is the utility model floating experiment instrument structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the floating experiment instrument of the utility model for imparting knowledge to students, comprises vial 1, micro air pump 2, rain glass 3, blowdown valve 5 and Cartesian diver.Load water in vial 1, Cartesian diver is positioned in vial 1, and the bottleneck of vial 1 adopts rubber plug 9 to seal.Micro air pump 2 is communicated with vial 1 by tracheae 4, and the front end connection metal pipe 10 of tracheae 4, metal tube 10 is inserted through rubber plug 9 and stretches in vial 1.Tracheae 4 between micro air pump 2 with vial 12 is connected rain glass 3.Blowdown valve 5 is communicated with vial 1 by tracheae 4, and the front end connection metal pipe 10 of tracheae 4, metal tube 10 is inserted through rubber plug 9.
Cartesian diver is less than the vial 6 of vial 1 bore, intake-discharge pipe 7 and bottle stopper 8 by external diameter and forms, and filling with in vial 6 has appropriate water, at the bottom of intake-discharge pipe 7 to extend bottle through bottle stopper 8.Cartesian diver 6 is placed upside down in and is equipped with in the vial 1 of suitable quantity of water.
The utility model adopts micro air pump 2 to pressurize, and the common feeders such as inflator also can be adopted to pressurize in actual experiment process.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
