Description
Technical field
The utility model belongs to teaching aid technical field, is specifically related to a kind of formation demonstration box of wind.
Background technology
Picture schematic diagram is used in teaching material, allow student copy test, instrument room does not provide such experiment equipment yet, and only have the experiment material that another kind of simple paper web does, paper web bottom has a small sircle hole, a short candle, during experiment in paper cylinder lighted candle, by the air heating in paper web, make thermal current increase, light the below that a mosquito-repellent incense is placed on small sircle hole outside paper web, can see that the smog of mosquito-repellent incense enters paper web and discharges with air-flow rising.Although experiment can be successful, the effect observed is not very desirable, not alike with the wind (level is drifted about) of occurring in nature, and student is it is seen that a kind of phenomenon not having wind---smog straight line rises.This material that instrument room provides also also exists potential safety hazard, and candle is in paper web combustion, of long duration, and paper web can burn, and can only require that student just to see after experimental phenomena extinguishing candles at once, and like this, what be unfavorable for that student formed wind probes into.The formation demonstration demonstration box of prior art apoplexy all can not regulate fragrant height, fragrant too short or oversizely all can not draw good test effect.
Utility model content
In order to overcome the defect of prior art, the utility model provides a kind of formation demonstration box of wind.
The formation demonstration box of wind, comprise the casing of rectangular parallelepiped and be located at the base of bottom half, casing and base are integrated, the width of base is greater than the width of casing, base forms a platform than casing width section on the right side of casing, casing top left side is provided with chimney, casing top center place is provided with handle, it is view window before casing, view window is transparent sliding glass door, the right side wall of casing is provided with circular hole, and the platform of the corresponding below of circular hole is provided with fragrant seat, and the platform that glass door is corresponding is provided with V-type groove.
The material of described chimney is stainless steel, and the top opposing floor portion of fragrant seat can spinning in and out.
First the utility model arranges handle at casing top, be easy to carry, secondly fragrant seat is set in the below of circular hole, the top opposing lower portions of fragrant seat can spinning in and out, thus change fragrant height, make test effect better, be sliding glass door before casing, conveniently fetch candle and lighted candle.
The utility model is skillfully constructed, and design science is reasonable, is convenient to student's probing into the formation of wind.
Accompanying drawing explanation
