Abstract
The utility model relates to a carbon dioxide experiment demonstration device, which is the improvement of the structure of a teaching aid and has the advantage that no error is caused. The demonstration device comprises a transparent box body with an upward opening and is structurally characterized in that a partition with a downward opening is upright arranged in the transparent box body and a candle is arranged in the transparent box body at a position on one side of the partition.
Description
Technical field:
The utility model relates to the improvement of teaching aid structure, relates in particular to a kind of carbon dioxide experimental demonstration device.
Background technology:
The density of carbon dioxide is bigger than air, and neither burning is not supported in burning yet.Existing carbon dioxide experimental demonstration device is that two candles are set in the beaker, and the teacher is easy to make mistakes when doing experimental demonstration, and the candle that makes eminence sometimes goes out earlier than the candle of lower, and two candles do not go out sometimes.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of carbon dioxide experimental demonstration device that can not make mistakes is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises the transparent casing of top opening, vertically is provided with the dividing plate that the below has opening in the transparent casing of its structural feature, is provided with candle in the transparent casing of dividing plate one side.
The beneficial effects of the utility model:
Owing to vertically be provided with the dividing plate that the below has opening in the transparent casing of the present utility model, be provided with candle in the transparent casing of dividing plate one side, carbon dioxide is poured in the transparent casing of dividing plate opposite side, therefore, when doing experiment, can not make mistakes.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises the transparent casing 1 of top opening, vertically is provided with the dividing plate 3 that the below has opening 2 in the transparent casing 1, is provided with candle 4,5 in the transparent casing 1 of dividing plate 3 one sides.
Experimental requirement, candle 4,5 of the present utility model is set to one high and one low two.
Below in conjunction with description of drawings principle of work of the present utility model:
When using, carbon dioxide is poured into a side that does not have candle 4,5 in the transparent casing 1, carbon dioxide enters a side that is provided with candle 4,5 by the opening 2 of dividing plate 3 belows, because the density of carbon dioxide is bigger than air, neither burning is not supported in burning yet, so low candle 5 extinguishes earlier, extinguish behind the high candle 4.
Claims (2)
1, a kind of carbon dioxide experimental demonstration device, the transparent casing (1) that comprises the top opening, it is characterized in that vertically being provided with the dividing plate (3) that the below has opening (2) in the transparent casing (1), be provided with candle (4,5) in the transparent casing (1) of dividing plate (3) one sides.
2, a kind of carbon dioxide experimental demonstration device according to claim 1 is characterized in that candle (4,5) is set to one high and one low two.
