Abstract
The utility model relates to a teaching aid for demonstrating the atmospheric pressure principle. The teaching aid is a pot with two separable pot cavities (6-1, 6-2). Two air holes (1-1, 1-2) separately communicating with the pot cavities are arranged above the handle in the pot body. Two pot cavities are provided with a water outlet hole (3-1, 3-2) respectively, a liquid in the pot flows out from a pot mouth (4) and the tops of the cavities are provided with a water inlet hole (2-1, 2-2) respectively which has a cover. The utility model clearly demonstrates the atmospheric pressure principle and can be used in physics teaching in primary and middle schools.
Description
Technical field
The utility model relates to the teaching aid field.Be specifically related to a kind of teaching aid of demonstrating the atmospheric pressure principle.
Background technology
The atmospheric pressure principle is that the middle school physics lesson must be learned one of content, and the utility model will provide a kind of entertaining teaching aid of demonstrating the atmospheric pressure principle.
Summary of the invention
The teaching aid of the disclosed demonstration atmospheric pressure of the utility model principle is one and has two kettles in isolated kettle chamber mutually, handle top respectively with about have two pores on the kettle body that communicates of two kettle chambeies, respectively there is an apopore in two kettle chambeies, liquid flows out by same Hu Zui in the kettle, at the top in two kettle chambeies two water injection holes of adding a cover is arranged respectively.
Respectively about inject the liquid of different colours in two kettle chambeies, cover the lid of tight water injection hole, according to the atmospheric pressure principle, when with thumb with about two air admission holes when all blocking, kettle is toppled over, Hu Zuichu does not go out liquid; When the air admission hole in the left side is discharged, the air admission hole in the right is blocked, and just can pour out the liquid in the kettle chamber, the left side, and does not go out the liquid in the kettle chamber, the right; Otherwise left side air admission hole is blocked, and the right air admission hole discharges, and just can pour out the liquid in the kettle chamber, the right; If two air admission holes are all discharged, can pour out the liquid of two kinds of colors simultaneously.
Can observe the effect of atmospheric pressure very intuitively by above-mentioned experiment.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings below:
As shown in Figure 3, left and right two kettle chambeies have air admission hole 1-1,1-2 respectively, and apopore 3-1,3-2 when pinning 1-1,1-2 hole simultaneously, topple over the kettle body, do not have liquid to flow out in the kettle mouth 4; When pinning the 1-1 hole, topple over the kettle body, liquid flows out through the 3-2 apopore among the 6-2; When pinning the 1-2 hole, topple over the kettle body, liquid flows out through the 3-1 apopore among the 6-1, and as not pinning 1-1,1-2 hole, then liquid flows out through 3-1,3-2 simultaneously among 6-1, the 6-2.
The utility model has been demonstrated the atmospheric pressure principle simply, legibly, can be used for the various physics teachings of middle and primary schools.
Claims (1)
1, a kind of teaching aid of demonstrating the atmospheric pressure principle, it is characterized in that this teaching aid is one and has two kettles in isolated kettle chamber (6-1,6-2) mutually, handle top respectively with about have two pores (1-1,1-2) on the kettle body that communicates of two kettle chambeies, respectively there is an apopore (3-1,3-2) in two kettle chambeies, liquid flows out by same Hu Zui (4) in the kettle, and two water injection holes of adding a cover (2-1,2-2) are arranged respectively at the top in two kettle chambeies.
