Abstract
The utility model provides an atmosphere existence demonstrating device capable of visually demonstrating the experimental phenomenon to the students, belonging to the technical field of the high-school physical experiment devices. The demonstrating device comprises a sink and a bottle provided with a stopper, and is characterized in that one end of a gas tube provided with a switch valve is arranged inside the water of the sink; the other end is arranged at the top of the bottle under a bottle stopper; and a long neck funnel is arranged inside the water of the bottle.
Description
Technical field:
The utility model is to belong to the middle school physical experiment device.
Background technology:
Traditional when the experiment that the demonstration air takes up space, its DeGrain, and directly perceived inadequately; Influenced teaching effect, be unfavorable for understanding and the grasp of student this part knowledge.
The utility model content:
The utility model is exactly at the problems referred to above, provides a kind of and can intuitively experimental phenomena be illustrated in the apparatus for demonstrating that student's atmosphere in front exists.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises tank, bottle with bottle stopper, its structural feature be have switch valve an end of wireway in the water of tank, the other end is arranged on the top of the bottle of bottle stopper lower end, long neck funnel is arranged in the water of bottle.
The beneficial effects of the utility model:
During use, at first, at this moment switch valve cuts out along long neck funnel water filling in bottle; Can see that the water in the long neck funnel does not flow in bottle; When switch valve is opened, can see the water diffluence in bottle in the long neck funnel; And the wireway that connects bottle immerses in the water, can find to have in the water bubble to emerge; Water is constantly injected by long neck funnel, and immersing in the water wireway will constantly have bubble to emerge to show that fully air takes up space; Not only improve student's learning interest, be beneficial to the understanding and the grasp of this chapter part knowledge again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises tank 8, has the bottle 2 of bottle stopper 4, and the end of wireway 5 with switch valve 6 is in the water 7 of tank 8, and the other end is arranged on the top of the bottle 2 of bottle stopper 4 lower ends, and long neck funnel 3 is arranged in the water 1 of bottle 2.
