Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawing.
The present invention provides a kind of glass for identification of hazing, as shown in Figure 1, including glass body 1, in glass body 1
Outer surface, at least one raised inclined-plane, including the first inclined-plane 2 are set along glass body direction, the outer surface of glass body 1 is also
It is provided with reflection optical receiving region 3, wherein reflection optical receiving region 3 is all-trans for receiving by glass body inner surface
The light penetrated, as shown in Fig. 2, it is preferred that reflection optical receiving region 3 is therefore the second inclined-plane 4 forms boss 5.
The present invention provides one kind and hazes detection device, including light source emitter 6, light source receiving device 7 and above-mentioned is used for
Haze the glass of identification, as shown in figure 3, include glass body 1 and with the integrally formed boss 5 of glass body, boss is set to
Glass body it is outwardly raised, wherein boss includes there are two inclined-plane, respectively the first inclined-plane 2 and the second inclined-plane 4 two
The bottom of slope on a inclined-plane is connect with 1 outer surface of glass body.
In order to avoid refraction influences measurement accuracy, the transmitting and reception of light source are all the surface on upright shoulders inclined-plane, because
This, light source emitter 6 is set to the outer surface on the first inclined-plane 2, for by the interior table of incident light vertical incidence to glass body 1
On face, and light source receiving device 7 is set to the outer surface on the second inclined-plane 4, for receiving the inner surface generation by glass body 1
The reflected light of total reflection.
According to ATR Optical principle, the cirtical angle of total reflection is that glass medium and air are situated between under glass surface clean state
Texture at the first set angle r, in the case where glass surface hazes state, the cirtical angle of total reflection is that glass medium and aqueous medium are constituted
The second set angle r0, wherein since the refractive index of air is less than the refractive index of water, r < r0, it follows that first is oblique
The angle R (angle less than 90 °) in face 3 and glass body direction is in the first set angle r and the second set angle range r0It is interior, i.e.,
r≤R<r0；Second inclined-plane is symmetrical arranged along the vertical direction in glass body direction and the first inclined-plane.
Light source emitter 6 and 7 spacing set distance of light source receiving device, wherein set distance size and inclination angle of inclined plane and
The thickness of glass body is related.
The course of work of the invention is as follows:
As shown in figure 3, the light of light source emitter vertically injects glass, and angle R is formed with the another side of glass, when
When R >=critical angle r, the light that light source emitter issues is totally reflected in interior surfaces of glass, and light is reflected by light source
Reception device receives；In such a way that judgement receives power of light etc., determines and be not actuated for demisting work at this time.
As shown in figure 4, when interior surfaces of glass hazes, there is the covering of droplet 8 on glass, at this time light and interior surfaces of glass
Angle r0> R >=r, light occurs refraction in interior surfaces of glass and cannot be totally reflected, therefore light source receiving device receives not
The light issued to light source emitter；In such a way that judgement receives power of light etc., determination is actuated for demisting at this time
Glass surface droplet 8 is removed in work, and after glass surface droplet is removed, light source receiving device can receive light again,
Demister stops working at this time.
As shown in figure 5, when interior surfaces of glass has droplet, it is possible to there is the phenomenon that part refraction is totally reflected with part, this
When the light that receives of light source receiving device, but light intensity dies down, therefore also can be concluded that the inner surface of windshield hazes, and opens
Demister carries out demisting.
Windshield hazes generally to be spread from corner inwardly, therefore, boss is set to the corner of the outer surface of glass
Position, and light source emitter and light source receiving device are set.
It is provided with boss on above-mentioned glass body, but is not limited to the glass shape in Fig. 2, as shown in Figure 6, Figure 7, only
The shape that boss to be presented in certain region all can be referred to as boss.The setting of reflection optical receiving region 3 is not limited to set
The mode on the second inclined-plane is set, as long as reflected light can reach light source receiving device 7, example by the outer surface of glass body
Such as, can also make to send out by inner surface by changing the outer surface contact medium with reflection 3 place glass body of optical receiving region
The light of raw total reflection will not be totally reflected in the outer surface；For another example, the second inclined-plane is changed to a spherical surface.
Specific embodiment of the present invention is presented above, but the present invention is not limited to described embodiment.
Under the thinking that the present invention provides, to the skill in above-described embodiment by the way of being readily apparent that those skilled in the art
Art means are converted, are replaced, are modified, and play the role of with the present invention in relevant art means it is essentially identical, realize
Goal of the invention it is also essentially identical, the technical solution formed in this way is to be finely adjusted to be formed to above-described embodiment, this technology
Scheme is still fallen in protection scope of the present invention.
