In transparent vessel bottom；The bottom end of tubule is inserted in one end of the moccasin pipe, and clip is equipped on moccasin pipe.
Further, the application further include: fill the container of liquor potassic permanganate, the other end of moccasin pipe protrudes into the container
In.
Further, transparent vessel bottom is equipped with the structure that raises upward.
Further, the intermediate position of tubule is fixed on transparent vessel bottom.
Further, clarification limewash is equipped in syringe.
Further, comburant is candle or charcoal or sulphur or phosphorus.
Further, the transparent vessel is plastic, transparent container.
Further, the clip is dovetail clip.
The utility model due to using the technology described above, can obtain following technical effect: Instrument Design novelty,

A variety of utility functions.
The instrument substantially increases the manipulative ability and interest of student, and keeps student saturating to the understanding of correlated knowledge point
It is thorough, deep, it can keep remembering for a long time；Time in classroom is also saved, more time in classroom are left for student, improves classroom effect
Rate, convenient for being widely applied in middle and primary schools.
Detailed description of the invention
The utility model shares 1 width of attached drawing:
Fig. 1 is a kind of multifunctional gas demonstration device structural schematic diagram；
Number explanation in figure: 1, syringe, 2, rubber stopper, 3, transparent vessel, 4, combustion spoon, 5, comburant, 6, moccasin pipe,

Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model demonstration device is described in detail in example.
Embodiment 1
The present embodiment provides include: syringe, transparent vessel, rubber stopper, combustion spoon, comburant, moccasin pipe, clip and thin
Pipe；The rubber stopper stoppers the bottleneck of transparent vessel, and the syringe needle that syringe is arranged on transparent vessel top, syringe passes through rubber
Rubber plug is placed in transparent vessel；Combustion spoon is additionally provided in transparent vessel, the top of the combustion spoon is hung on rubber stopper, burning
Object is placed on the pedestal of combustion spoon；The tubule is through transparent vessel bottom；It is inserted in the bottom of tubule in one end of the moccasin pipe
End, the other end of moccasin pipe are put in the container for filling liquor potassic permanganate, and clip is equipped on moccasin pipe.
This demonstration device embodies modularization teaching thinking, and multiple experimental phenomena consecutives are demonstrated, not only can be in school science
Demonstration comburant oxygen, carbon dioxide become cloudy clarification limewash, moreover it is possible to carbon, sulphur, phosphorus combustion are demonstrated in junior middle school, senior chemistry class
It burns, eventually forms beautiful fountain.The concrete operating principle of the demonstration device are as follows: be prepared in advance the injection equipped with clarification limewash
Device and the container for filling liquor potassic permanganate；Firstly, rubber stopper is pulled up, after putting lighted candle on combustion spoon, by rubber stopper plug
Tight bottleneck extinguishes to candle, and oxygen has been used up in transparent vessel, and by the clarification limewash in syringe, (water surface of limewash is high
Degree is lower than the height of container inner tubule), it injects in transparent vessel and jiggles, clarification limewash becomes cloudy, in transparent vessel
Carbon dioxide has been used up, and the air pressure in transparent vessel at this time is lower than external atmosphere pressure, and moccasin pipe is protruded into the potassium permanganate of container
In aqueous solution, clip is unclamped, beautiful fountain can be formed at this time；Candle is used instead to the wood of burning when carrying out chemical experiment in junior middle school
Candle is used instead sulphur, the phosphorus of burning when senior middle school carries out chemical experiment by carbon, does not have to clear limewash at this time, with clear water energy
Dissolved sulfur dioxide, phosphorus pentoxide.
Therefore the burning of carbon, sulphur, phosphorus substance, the different liquid of gas of formation can be demonstrated, be observed to the demonstration device of the application
After processing, beautiful fountain is formed, whole process is completed with an instrument is coherent, and it is easy to operate, change Traditional Scientific, Chemistry Courses
A kind of middle experimental phenomena one is demonstrated, and troublesome, the unworkable phenomenon with different instruments, while allowing student's profound understanding stream
The principle of body movement, had both broken through the difficult point of experimental teaching, had given top priority to what is the most important, and saved time in classroom, improved classroom efficiency.
The above, only the utility model create preferable specific embodiment, but the protection that the utility model is created
Range is not limited thereto, and anyone skilled in the art creates the technical scope disclosed in the utility model
Interior, technical solution and its utility model design created according to the utility model are subject to equivalent substitution or change, should all cover
Within the protection scope that the utility model is created.
