Abstract
An educational demonstration device of detonating the combustible gas in electronic is disclosed. A gas collecting box 2 is actively placed on a fixed plate 1, and the other surfaces of the gas collecting box 2 are all sealed other than the bottom. A metal gas inlet pipe 3 is fixed on the fixed plate 1, and an air outlet of the metal gas inlet pipe 3 is positioned in the gas collecting box 2. A positive pole of an electronic arcing device 4 is positioned near the air outlet of the metal gas inlet pipe 3, and the negative pole is connected with the metal gas inlet pipe 3. The utility model has the advantages of convenient and safe operation, high success rate, and fully guiding and developing the student intelligence, and good demonstration effect, as well as saving energy and saving time.
Description
The utility model relates to instruments used for education.
At present, in teaching in order to make the student understand inflammable gas such as hydrogen, when in a single day carbon monoxide etc. reach the certain volume mark with air mixed, meet the fact that fire will be blasted, be that the inflammable gas that inflammable gas generator is produced is introduced in the paper web of a uncovered inversion desktop by draft tube, have an aperture at the top of paper web, before the experiment, the aperture at the top of paper web is clogged, after the inflammable gas of gas generator generation enters paper web, because inflammable gas is light than air, inflammable gas is just discharged the air in the paper web downwards, after in estimating paper web, being full of inflammable gas, remove gas generating unit, the aperture at paper web top is opened the inflammable gas of lighting effusion rapidly, inflammable gas reduces because of burning in the paper web, and air replenishes to enter in the paper web fast from the bottom of paper web and mixes and will blast with inflammable gas, thereby starts carton is high.This method weak point is operation inconvenience, and success ratio is not high, is not easy to the observation of students thinking.
The purpose of this utility model is exactly to provide a kind of electronics to ignite teaching demonstration device, easy to operate, safety, success ratio height at the deficiency of the igniting method of above-mentioned teaching demonstration.
Electronics is ignited the teaching demonstration device of inflammable gas, it is characterized in that: collect box 2, metal gas inlet pipe 3 and electronic striking device 4 by fixed head 1, combustion gas and form, combustion gas is collected box 2 activities and is placed on the fixed head 1, combustion gas is collected box 2 except that the bottom, other several times all seal, metal gas inlet pipe 3 is fixed on the fixed head 1, the gas outlet of metal gas inlet pipe 3 is positioned at combustion gas and collects box 2, the positive pole sparking termination of electronic striking device 4 is positioned at by the gas outlet of metal gas inlet pipe 3, and negative pole connects metal gas inlet pipe 3.Also be fixed with a line 5 on fixed head 1, the other end of line 5 is fixed on combustion gas and collects on the box 2, and box 2 usefulness metals or plastics manufacturing are collected in combustion gas.
Advantage of the present utility model is easy and safe to operate, and the success ratio height can fully guide and develop students intelligence, and good demonstration effect is during energy-conservation joint.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: fixed head 1 is used plank, make a call to a circular hole at fixed head 1 center, the gas inlet pipe 3 that metal such as iron or copper are done passes from the circular hole of fixed head, does combustion gas with the expendable transparent plastic water tumbler and collects box 2, and it is covered on the gas outlet of gas inlet pipe 3.Box is collected in combustion gas and fixed head connects together with a line 5, the electronic striking device just gets final product with the used electronic striking device of disposable lighter, the positive pole of electronic striking device sparking termination is placed in by the gas inlet pipe gas outlet, and negative pole links to each other with the gas inlet pipe that iron or copper are done.During the experiment beginning, the air intake opening of gas inlet pipe is connected with the gas outlet of hydrogen generator, open the hydrogen generator switch, hydrogen enters by gas inlet pipe and collects in the box, the air of collecting in the box is discharged from the bottom of unencapsulated box, after about 10 seconds, close hydrogen generator, press the switch of electronic striking device, produce spark between the gas inlet pipe gas outlet that the positive pole sparking termination of electronic striking device and iron or copper are done, will ignite hydrogen and the Air mixing gas collected in the box.Blast will be collected box and start, because the effect of line 5, the collection box can disorderly not fly, and reusable.Collecting box because of combustion gas is that uncovered, transparent plastic is manufactured, and does not have any danger, and can allow the student see through plastic cup to can be observed the spark that instant of detonation is flashed, strengthened the demonstration effect.
