Abstract
The utility model relates to an inflatable structure for the experiment balloon in physics teaching. The prior inflates for experimental balloon provide hot blast by using open flame, which is extremely unsafe and is a great threat to the balloon of light quality material. The utility model proposes a simple and convenient, safe technological proposal; an inflatable structure of experimental balloon comprises a balloon, a wind guide cylinder and an electric hair dryer. It is characterized in that the electric hair dryer blasts hot wind into the balloon through wind guide cylinder and makes the balloon with full of hot air, then the balloon arises and stays in air above 30 seconds as usual. The utility model is characterized in extremely simple materials, manufacturing method, adopting the electric hair dryer used in family to provide hot air source, rather than the open flame, which is safe and stable in performance, also arrives the target for verifying gas experiment law.
Description
Technical field
The utility model relates in a kind of physics teaching about the experimental setup of calorifics, particularly relates to the relevant fire balloon inflation method and the device of calorifics part in the relevant physics teaching.
Background technique
Many physical phenomenons in the real life about calorifics and pneumatology, as engineer operations such as blast, explosions, dynamic power machines such as steam engine, internal-combustion engine, steam turbine, jet engine have all been used calorifics knowledge, the gas of certain mass, certain relation is all arranged between its pressure, volume and the temperature, in education experiment, the experiment of a fire balloon is done in the capital, to verify the principles of science: " when the density of balloon interior hot air during less than the density of balloon outside air, balloon can go up to the air ".In the balloon made from lightweight materials such as paper, fabric or plastic pellicles, feed hot air, fire balloon can be risen slowly, the general air-supported structure of making hot air all is the hot air flow that adopts alcohol lamp, cured candle, blowtorch or solid alcohol and so on burning to produce, this use naked light provides hot air flow, be absolutely unsafe, the balloon that lightweight material is made is great threat.
Summary of the invention
In order to overcome the deficiency that prior art exists, the utility model proposes a kind of easy, the technological scheme of safety, the technical solution of the utility model is to come specific implementation by following technical measures, a kind of air-supported structure of experiment hot air balloon, it is characterized in that it is by balloon 1, wind-guiding cylinder 2 and hair drier 3 are formed, wherein: balloon 1 adopts papery, fabric or plastic pellicle are made, papery wind-guiding cylinder 2 inserts in balloon 1 bottom circular aperture, 110W or 220W hair drier 3 insert and are blown into hot blast in wind-guiding cylinder 2 in balloon 1, after balloon 1 being sticked out be full of hot air, remove hair drier 3 and wind-guiding cylinder 2, the bottom circular aperture of sealing balloon 1, balloon 1 promptly can become a fire balloon to rise slowly, and airborne period generally can reach more than 30 seconds.
Advantage of the present utility model is that making method, the desirable with hands down household electric blower machine of employing provide heated air source easily with open-and-shut material, the utmost point for it, save the use of naked light, not only safety, but also reliable, reached the gas experiment law of " when the hot air density of balloon interior during less than the density of balloon outside air, balloon can go up to the air " equally.

The meaning that each legend mark respectively is expressed as follows in the accompanying drawing:
The 1----balloon; 2----wind-guiding cylinder; The 3----hair drier;
D
1----be 1/3 place's diameter apart from the top; D
2----be 2/3 place's diameter apart from the top; D
3----cylinder 2 diameters;
H----balloon 1 height.
Embodiment
In conjunction with the embodiments with accompanying drawing 1,2, the utility model is further described below:
Press the structural requirement of accompanying drawing 2,, be cut into 8 of both sides arc, biapiculate shapes broad in the middle the plastic pellicle five equilibrium, be glued together with adhesive tape, make a balloon, a circular hole is reserved in the bottom, become a cylinder to make wind-guiding usefulness paper roll, the cylinder size can just in time be filled in the circular hole that the balloon bottom is reserved.The concrete size of the balloon of making (seeing accompanying drawing 2) is: D
1Be φ 850mm; D
2Be φ 600mm; D
3Be φ 70mm; H is 1000mm.During experiment, adopt 220W hair drier commonly used in the daily life 3 to insert wind-guiding cylinder 2 places and in balloon 1, blow hot gas, after balloon 1 is full of hot gas, remove hair drier 3 and wind-guiding cylinder 2, sealing balloon 1 bottom circular aperture, balloon 1 promptly can become fire balloon and rise slowly, and airborne period can reach more than 30 seconds.
