Abstract
The utility model discloses a kind of environment to biotic influence experimental provision, belong to teaching aid technical field, this device is made up of two identical inspection boxes, gas generator, blower fan, common three-way pipe, special three-way pipe, several wireways, described two identical inspection boxes transparent be connected be designed with the observation and contrast that are beneficial to test organism; Described blower fan provides same air to two casees, gets rid of natural air to the impact of bioorganism, sends into experimental gas simultaneously in treatment box; Baffle design in described special three-way pipe can ensure that two air capacities that inspection box enters are identical, and activated charcoal can to air cleaner.The utility model structure is simple, is convenient to make, and factor of removing all kinds of obstacles ensures experimental result accurately and reliably.
Description
Technical field
The utility model belongs to teaching aid technical field, is specially a kind of environment to biotic influence experimental provision.
Technical background
Affect a lot of because have of biological growth, gas is one of key factor affecting biological growth, this is the important content in biological course, but there is no corresponding experimental provision in existing laboratory, student cannot observe directly the impact of gas on biological growth, lack persuasion, understanding is not deep, therefore makes an environment and just seems necessary to biotic influence experimental provision.
Summary of the invention
Cannot probe into interactional deficiency between biology and environment to overcome existing experimental provision, the utility model provides a kind of environment to biotic influence experimental provision.
The technical scheme that the utility model adopts is: a kind of environment is to biotic influence experimental provision, be made up of two identical inspection boxes, gas generator, blower fan, common three-way pipe, special three-way pipe, several wireways, it is characterized in that, described two identical inspection boxes are that two hollow transparent body are connected as a single entity, and are for one case wherein treatment box, and another case is contrast case, there is lid box top, cover and be provided with perforate, case side lower part is provided with intake interface, can place experimental plant in case; Described gas generator can produce experimental gas; Described fan action is to provide aerodynamic force, gets rid of natural air to the impact of experimental plant, sends into experimental gas simultaneously in treatment box; Be provided with dividing plate in described its intervalve of special three-way pipe, spacer function is that guarantee two air capacities that inspection box enters are identical, and dividing plate top is placed with activated charcoal, and activated charcoal effect is to air cleaner, avoids interference factor; Three mouths of pipe of described common three-way pipe are connected with the intake interface for the treatment of box, gas generator, special three-way pipe respectively by wireway, three mouths of pipe of special three-way pipe are connected with the intake interface of contrast case, blower fan, common three-way pipe respectively by wireway, wherein special three-way pipe to be given a dinner for a visitor from afar machine with the mouth of pipe of activated charcoal, and all connections are airtight connection.
The utility model beneficial effect is: two identical inspection boxes transparent be connected be designed with the observation and contrast that are beneficial to test organism; Blower fan provides same air to two casees, gets rid of natural air to the impact of bioorganism, sends into experimental gas simultaneously in treatment box; Baffle design in special three-way pipe can ensure that two air capacities that inspection box enters are identical, and activated charcoal can to air cleaner.The utility model structure is simple, is convenient to make, and factor of removing all kinds of obstacles ensureing experimental result accurately and reliably, as coordinated other biological physiology analytical equipment, can also carry out the further investigation of biological physiology aspect.
Accompanying drawing explanation
If Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of environment is to biotic influence experimental provision, be made up of two identical inspection boxes, 1, gas generator, 12, blower fan, 11, common three-way pipe, 13, special three-way pipe 8, several wireways 7, it is characterized in that, described two identical inspection boxes 1 are that two hollow transparent body are connected as a single entity, and are for one case wherein treatment box 15, and another case is contrast case 4, there is lid 3 box top, cover and be provided with perforate 2, case side lower part is provided with intake interface 6,14, can place experimental plant 5 in case; Described gas generator 12 can produce experimental gas; Described blower fan 11 effect is to provide aerodynamic force, gets rid of natural air to the impact of experimental plant 5, sends into experimental gas simultaneously in treatment box 15; Be provided with dividing plate 9 in described its intervalve of special three-way pipe 8, dividing plate 9 effect be guarantee two inspection boxes 1 to enter air capacity identical, dividing plate 9 top is placed with activated charcoal 10, and activated charcoal 10 effect is to air cleaner, avoids interference factor; Three mouths of pipe of described common three-way pipe 13 are connected with the intake interface 14 for the treatment of box 15, gas generator 12, special three-way pipe 8 respectively by wireway 7, three mouths of pipe of special three-way pipe 8 are connected with the intake interface 6 of contrast case 4, blower fan 11, common three-way pipe 13 respectively by wireway 7, wherein special three-way pipe 8 to be given a dinner for a visitor from afar machine 11 with the mouth of pipe of activated charcoal 10, and all connections are airtight connection.
The utility model is operation like this: the lid 3 first opening two inspection boxes 1, puts into some experimental plants of the same race 5, builds lid 3; Then blower fan 11 is opened, until the air of two inspection boxes 1 is all changed to the clean gas after activated charcoal 10 purifies; Open gas generator 12 subsequently, the experimental gas of generation is with air flow treatment box 15, and the experimental plant 5 observed inside two inspection boxes 1 changes, and the experimental plant 5 of contrast treatment box 15 and contrast case 4 is different.In experimentation, blower fan 11 works all the time, until experiment terminates, and gas generator 12 experimentally needs to determine the opening time.
