Abstract
One utilizes atmospheric pressure intuitively to react the demonstration teaching aid of " harm of smoking ", comprises headpin 1, No. 2 bottles 2, No. 3 bottles 3, No. 1 flexible pipe 4, No. 2 flexible pipes 5, No. 3 flexible pipes 6, pump bowls 7; Described headpin 1, No. 2 bottles 2, No. 3 bottles 3 are the identical transparent closed container of specification; Described No. 3 bottles 3 are tester; The rim of a cup of headpin 1 is exposed in described No. 1 flexible pipe 4 one end, the other end submerge headpin 1 liquid level under; Described No. 2 flexible pipe 5 one end are inserted on headpin 1 liquid level, the other end submerge No. 2 bottles 2 liquid level under; Described No. 3 flexible pipe 6 one end are inserted on No. 2 bottle 2 liquid levels, and the other end connects pump bowl 7; The utility model, by comparison, intuitively, effectively can reflect " harm of smoking " this scientific judgment.
Description
Technical field
The utility model relates to demonstration teaching aid, is specifically related to one and utilizes atmospheric pressure intuitively to reflect the demonstration teaching aid of " harm of smoking ".
Background technology
" harm of smoking " this proposition becomes final conclusion in science, and government is also by various ways limitation of smoking, but for various reasons, " harm of smoking " does not also form proprietary common recognition.And on teaching demonstration, people be allowed intuitively to approve " harm of smoking ", also there is no a demonstration teaching aid.
Summary of the invention
The purpose of this utility model is to provide a kind of demonstration teaching aid of directly perceived, simple, successful, and convenient operation can reach rapidly again the demonstration purpose of " harm of smoking ".
For achieving the above object, the utility model one utilizes atmospheric pressure intuitively to reflect, and the technical scheme of the demonstration teaching aid of " harm of smoking " is: one utilizes atmospheric pressure intuitively to reflect the demonstration teaching aid of " harm of smoking ", comprises headpin 1, No. 2 bottles 2, No. 3 bottles 3, No. 1 flexible pipe 4, No. 2 flexible pipes 5, No. 3 flexible pipes 6, pump bowls 7; Described headpin 1, No. 2 bottles 2, No. 3 bottles 3 are the identical transparent closed container of specification; Described No. 3 bottles 3 are tester; The rim of a cup of headpin 1 is exposed in described No. 1 flexible pipe 4 one end, the other end submerge headpin 1 liquid level under; Described No. 2 flexible pipe 5 one end are inserted on headpin 1 liquid level, the other end submerge No. 2 bottles 2 liquid level under; Described No. 3 flexible pipe 6 one end are inserted on No. 2 bottle 2 liquid levels, and the other end connects pump bowl 7.
For making experiment effect remarkable, it is airtight that each several part connects needs.
The utility model has the principles of science, and make simple, demonstration is convenient, visual phenomenon, the advantages such as Be very effective.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is that the utility model one utilizes atmospheric pressure intuitively to reflect the structural representation of the demonstration teaching aid of " harm of smoking ".
Embodiment
One as shown in Figure 1 utilizes atmospheric pressure intuitively to reflect the demonstration teaching aid of " harm of smoking ", comprises headpin 1, No. 2 bottles 2, No. 3 bottles 3, No. 1 flexible pipe 4, No. 2 flexible pipes 5, No. 3 flexible pipes 6, pump bowls 7; Described headpin 1, No. 2 bottles 2, No. 3 bottles 3 are the identical transparent closed container of specification; Described No. 3 bottles 3 are tester; The rim of a cup of headpin 1 is exposed in described No. 1 flexible pipe 4 one end, the other end submerge headpin 1 liquid level under; Described No. 2 flexible pipe 5 one end are inserted on headpin 1 liquid level, the other end submerge No. 2 bottles 2 liquid level under; Described No. 3 flexible pipe 6 one end are inserted on No. 2 bottle 2 liquid levels, and the other end connects pump bowl 7.
During experiment, first the cigarette that is lighted is inserted in one end that No. 1 flexible pipe 4 exposes air, then bleeds with pump bowl 7; When bleeding, the atmospheric pressure of No. 2 bottles 2 reduces, and the air of headpin 1 will come in supplement by No. 2 flexible pipes 5, and now the pressure of headpin 1 can reduce, and the air outside bottle can be supplemented into by No. 1 flexible pipe 4, thus drives flue gas to enter headpin 1; When flue gas passes through the clear water of headpin 1, the objectionable impurities of flue gas can a part " be retained " by water, thus makes the clear water of headpin 1 become faint yellow; Further, the flue gas brought from headpin 1 along with No. 2 flexible pipes 5 enter No. 2 bottles 2 time, the clear water of No. 2 bottles 2 " can retain " part objectionable impurities again, and when flue gas is gone out from pump bowl 7 eventually through No. 3 flexible pipes 6, remaining objectionable impurities can pollute No. 3 flexible pipes 6 and pump bowl 7; So repeatedly bleed with pump bowl 7, when after a cigarette burning-out, the liquid in headpin 1, No. 2 bottles 2 and the liquid color in No. 3 bottles 3, smell are contrasted, significantly can reflect " harm of smoking " this conclusion.
After experiment terminates, demonstration teaching aid is cleaned up, be beneficial to continue next time to use.
