Description

A kind of double glazing smart window
Technical field
The present invention relates to smart window technical field, more particularly to a kind of double glazing smart window.
Background technology
Window refers to the hole built on wall or roof on architecture, get in light or air. Curtain is by making such as cloth, fiber crops, yarn, aluminium flake, wood chip, metal materials, with sunshading and heat-insulating and regulation The function of indoor light.Traditional curtain is typically made using cloth or fiber crops, yarn, when use, by curtain Pull on, however, such curtain has easily dirty, cumbersome defect, based on this, people devise A kind of shutter, is connected together as curtain using multiple blades and uses, when use, as long as pulling The chain rope of side can be blocked rapidly to window, when unlatching, and reverse pulling chain rope can be quick Ground open curtain, however, this curtain there is also some defects it is such as dirty when cleaning be difficult, installation it is cumbersome Deng.
The content of the invention
In view of the technical drawbacks of the prior art, it is an object of the present invention to provide a kind of double glazing intelligence Can window.
To realize the purpose of the present invention, the technical scheme used is：A kind of double glazing smart window, including Forms and glass, the glass are dimming glass, and the dimming glass includes first layer glass and second layer glass Glass, light modulation layer, the light modulation layer and power circuit are sandwiched between in the first layer glass and second layer glass Connection, the light modulation film layer from top to bottom includes upper electrode layer, polymer dispersed liquid crystal layer, electrochromic layer And lower electrode layer.
Wherein, the first etch resistant layer is additionally provided between the upper electrode layer and the polymer dispersed liquid crystal layer； And/or the second etch resistant layer is additionally provided between the lower electrode layer and the electrochromic layer.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is adjusted by being set on dimming glass Photosphere so that without setting the structures such as curtain, shutter to block window, dimming glass is uncharged In the case of, in non-pellucidity, after charging, in pellucidity, so as to rapidly realize It is switched fast between transparent and opaque two states, also eliminates cumbersome installation and be difficult to cleaning Problem, at the same it is both artistic and practical, it is easy to industrially carry out promotion and application.
Brief description of the drawings
