Description
Technical field
The utility model relates to technical field of experiment equipment, in particular to a kind of rainbow experiment instrument.
Background technique
After the rain in summer, on high in will appear zingy rainbow often, the light of everybody mystery this to nature
It is very curious to learn phenomenon.The principles of science of rainbow has got across by the unremitting effort of numerous scientists after rain, summarizes and
Say that rainbow is a kind of optical phenomena.It is due to left floating a large amount of small rain droplets after rain in air, solar irradiation is mapped in small rain droplets,
There is some light to enter inside small rain droplets after small rain droplets surface reflects, reflects in small rain droplets inner surface, most pass through afterwards
It crosses and is refracted off small rain droplets again, be exactly that primary event reflects twice, it is various since sunlight is that various monochromatic light are combined
Light is different to the refractive index of water, for example feux rouges refractive index is 1.331；Yellow light refractive index is 1.333；Green light refractive index is 1.337；
Purple light refractive index is 1.343.Therefore the dispersion of light is produced in this process, when people facing away from sun viewing water droplet, so that it may see
To the colored circular arc for being followed successively by red, orange, yellow, green, blue, blue, purple from top to bottom, here it is rainbows.
We also have such experience in life, near fountain or waterfall, or even manually with watering can in sunlight
Lower water spray can observe rainbow phenomena in specific angle.The condition or partial condition for borrowing nature can reproduce
Rainbow phenomena after rain.Rainbow phenomena is related to a large amount of scientific knowledges behind, not only contains optical knowledge abundant, further relates to
Mathematical knowledge etc., the color in conjunction with its abundant change is the typical example taught through lively activities.However it is after all by natural conditions
Limitation, cannot observe and study whenever and wherever possible, such as in the case where no sun light direct beam, just be difficult to carry out rainbow experiment.
Therefore, as can non-solar light irradiation rain reproduce after rainbow phenomena, it appears it is very significant.
So far, there are some technologies about the simulation demonstrating apparatus of rainbow phenomena after indoor reproduction rain.Such as special
A kind of multiple rainbow demonstration device is disclosed in sharp CN102637379A, this device is to be produced with laser pen class light source by water droplet
Raw light demonstrates multiple rainbow in annular optical screen indirectly.Other than above-mentioned patent, disclosed in patent CN201667161U
A kind of cooperation using special screen and light source simulates rainbow phenomena, and a kind of laser pen is disclosed in patent CN203588546U
Laser light splitting phenomenon occurs by multiple refraction to demonstrate rainbow by thin-walled glass, above several patented technologies are all a kind of
The device of indirect analog rainbow phenomena, experiment effect is not intuitive enough, and teaching is weaker.In addition, being disclosed in patent CN2498686
Rainbow condition makes a kind of rainbow-forming demonstrator after a kind of rain that almost copying nature, uses in light source part
The sun of light or other light sources as sky.But the demonstration device volume is larger, uses very inconvenient, teaching is still
It is weaker.
A kind of Raibow equipment is disclosed in patent CN1778446, although the structure of the patent is smaller, only by watering can and flashlight
Cylinder is constituted, but the patent is undisclosed for flashlight portion detailed, need to know that conventional flashlight is to be difficult to issue satisfaction formation
The directional light of condition needed for rainbow.Rainbow, Er Qietai usually after bright day gas rather than cloudy day can observe rain
Intensity of sunlight minimum, which requires to reach 20000lx, could generate rainbow, thus the parallel composite light source of high illumination is rainbow simulation
Successful primary condition.And the technical solution is difficult to successfully form rainbow from the point of view of its structure and literature record.

Collimation focusing lens group 24 is provided with light inlet window 281 on opposite side.
If water mist spraying head 12 and light inlet window 281 are relatively close, when water mist spraying head 12 sprays water mist, water mist attachment is inevitably had
On light inlet window 281, thus influence whether that parallel compound strong light is got.Therefore, more preferably, in the technology of the present embodiment
In scheme, water mist spraying head 12 stretched out from hand-held sandwich type element 11 it is mutually separate with light inlet window 281, to avoid water mist from being attached to as far as possible
On optical window 281.
It should be noted that, although having been done to parallel optical transmitting set 20 small-sized in the technical solution of utility model
Change processing, but because the focal length of lens requires and the requirement of the voltage electricity of power supply, so that the length and body of parallel optical transmitting set 20
Product is still difficult to singlehanded grasp.Therefore, in the technical scheme of this embodiment, as shown in Figure 1, being formed on hand-held sandwich type element 11
First holding part 111 and with spaced second holding part 112 of the first holding part 111, Operation switch 13 setting is held first
Portion 111 is held nearby or near the second holding part 112.In this way, operator can with the hands hold the first holding part respectively
111 and second holding part 112, rainbow experiment instrument is held and is tested.Operation switch 13 is arranged attached in the first holding part 111
Near close or the second holding part 112, so that it may the hand for holding the first holding part 111 or the second holding part 112 be allowed to separate one
Root or two fingers press Operation switch 13.So, the more convenient to use of rainbow experiment instrument can be made.
More preferably, as shown in Figure 1, in the technical scheme of this embodiment, hand-held atomizer 10 further includes pressurization
Mechanism 14, pressing mechanism 14 are arranged on hand-held sandwich type element 11, and pressing mechanism 14 into water storage space for pressurizeing.Based on the reality
Mode is applied, water mist spraying head 12 is only connected to by suction pipe with water storage space, control of the Operation switch 13 as control suction pipe on-off
Valve processed uses.
As another optional embodiment, pressing mechanism 14 can not also be used, Operation switch 13 and one are pressed
Water dispenser structure is connected, and squeezer structure is allowed to absorb water out of water storage space, resupplies the ejection of water mist spraying head 12.The principle and general
Watering can principle is identical, what those skilled in the art also can be achieved on.
As shown in Figure 1, being provided with filler 113 on hand-held sandwich type element 11, lid, lid are provided on filler 113
It is detachably connected with filler 113.In the water storage space of hand-held sandwich type element 11 when water shortage, lid can be opened, to water storage
Add water in space, closes the lid again after adding water.
The utility model has the beneficial effect that equipment volume is small and exquisite compared with prior art, and light source is parallel compound
Light intensity light source observes directly rainbow phenomena after the rain of clear distinctness, ensure that the science of lecture experiment.
