Abstract
The utility model, which relates to the technical field of the teaching experimental apparatus, provides an experimental apparatus of the current chemical effect. The experimental apparatus is characterized in that the apparatus is composed of an intermediate injector needle tube, injector needle tubes at two sides, pistons, injection needle sleeves, a fountain pen refill, pencil leads, a sealed sleeve, and a bottle cover. The head of the intermediate injector needle tube is arranged downwardly and is fixed at the bottle cover; and the sealed sleeve is arranged at the injection port of the intermediate injector needle tube. Two injector needle tubes are arranged at two sides of the intermediate injector needle tube and the heads of the two injector needle tubes are arranged upwardly; the two injector needle tubes at two sides are respectively fixed with the intermediate injector needle tube by the fountain pen core and are communicated internally; the pistons are respectively arranged at the bottoms of the two injector needle tubes at two sides; the pencil leads are arranged and inserted into the pistons; and the injection needle sleeves are respectively arranged at the injection ports of the two injector needle tubes at two sides. According to the scheme, the provided experimental apparatus with the simple structure can be used conveniently; the teaching cost is lowered; and the experiment exploration enthusiasm of students can be aroused.
Description
Technical field:
The utility model relates to teaching and experiment equipment technical field, specifically electric current chemical effect experiment instrument.
Background technology:
Teaching and experiment equipment, the instrument of using while being natural science specific experiment, is mainly that physics, chemistry, biology are used instrument more.The experimental apparatus structure being particularly applied in middle and primary schools is generally all fairly simple, the content of experiment is also very simple, the experimental apparatus of the principles such as a lot of reaction physics or chemistry can oneself all be received making, but in prior art, the experimental apparatus of the real manual fabrication of student is little, do not know how to go to make yet, electric current chemical effect experiment instrument, it is very simple experimental apparatus in physics student teaching, but school buys these instruments, not only can improve the cost of teaching, and in the process of experiment, be difficult to cause that student starts or the interest of personal operating experience, the quality of teaching is also lower.
Utility model content:
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and reduces instruction cost, the hydraulic drive motor experiment instrument of Experimental Research enthusiasm that can mobilizing students.
The technical matters solving adopts following technical scheme:
Electric current chemical effect experiment instrument, it is characterized in that: comprise middle injector needle tubing, both sides syringe needle tube, piston, injection needle guard, water fillable, pencil-lead, sealing shroud and bottle cap, described middle injector needle tubing head towards and be fixed on bottle cap, described sealing shroud is arranged on the injection port of middle injector needle tubing, described both sides syringe needle tube comprises two and the head both sides that are arranged on middle injector needle tubing upwards, both sides syringe needle tube is fixed with middle injector needle tubing respectively by water fillable and inside is connected, described piston is separately positioned on the bottom of two both sides syringe needle tubes, described pencil-lead is arranged on and assigns on piston, described injection needle guard is separately positioned on the injection port of two both sides syringe needle tubes.
Described middle injector needle tubing is the needle tubing of 10 milliliters of plastic injectors, and described both sides syringe needle tube is the needle tubing of 2.5 milliliters of plastic injectors.
Described pencil-lead sees through the both end sides of piston.
Experiment is used:
Pull out injection needle guard, in 10ml middle injector needle tubing, pour appropriate water into, put injection needle guard, 6v direct supply is connected on two Pencil with 2B hardness cores, on two electrodes, just have bubble constantly produces for a moment, connect power cathode electrode produce bubble many, through inspection be hydrogen, connecing the bubble producing on anodal electrode is oxygen.Also can in instrument, add saline solution, copper-bath etc. to do the chemical effect experiment of electric current.
Experiment conclusion:
Between material, under the effect of electric current, can there is chemical change, produce new material, the chemical effect of Here it is electric current.
Experiment instrument design is unique, and experiment instrument is made simple, thereby applicable student's manual fabrication, and is all to adopt modal thing or used waste material in daily life, and cost is very low.When game experiment processing ease, the visual phenomenon of generation, obvious, interesting, game process safety, without harm hidden danger.
The interesting phenomenon producing when experiment instrument utilizes experiment cleverly, or apply the perceptual illusion to physical phenomenon, excite student's physics interest.In the moving mode of playing, carry out Physical Experiment inquiry activity, so just make Physical Experiment inquiry activity vivid and interesting, amusement, Experimental Research are organically combined, transfer the enthusiasm of student's Experimental Research.
Plastic injector for temporary use is changed system into electric current chemical effect experiment instrument.Experiment instrument can be used as the little experimental apparatus of physics, can be used as again physics toy.Can allow student have fun, realize and playing middle school, the teaching idea of playing in, allows student in playing, go to probe into physical principle, discloses the science reason in life.So just can allow needle tubing play out physical principle.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, reduce instruction cost, Experimental Research enthusiasm that can mobilizing students.
Brief description of the drawings:
Fig. 1 is the utility model structural representation.
