Specific embodiment
It will be appreciated that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
Its embodiment, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of Intelligent mirror, including half mirror, display panel, control panel and Resistant heating
Display panel is arranged in film, the half mirror back side, and the part of the half mirror back side removal display panel is covered
Lid Resistant heating film, the control panel are electrically connected with the display panel, the control panel and the Resistant heating
Film is electrically connected, and Temperature Humidity Sensor, the output end and control plane of the Temperature Humidity Sensor is arranged on the half mirror
The input terminal of plate is electrically connected, and the temperature-humidity signal control resistance wire that the control panel is detected according to the Temperature Humidity Sensor adds
Hotting mask heats the half mirror.The specific connection such as Fig. 2 to Fig. 5 of control panel and control panel and display panel
It is shown.
Resistant heating film and display panel are fixed on mirror back surface, that piece of Resistant heating film of display is engraved
Sky, other parts stick Resistant heating film, and display entire mirror surface when being not turned on seems to distinguish not with general mirror
Greatly, when display lights, using the principle of half mirror, non-display is partially due to back side black, from mirror surface
Front looks over as normal mirror, and display part can be clearly seen that due to the brightness of display through mirror surface
Display foregoing;The working condition that heating film is controlled by control panel, to control Resistant heating film to mirror
Heating.
Relay is set between preferred control panel and Resistant heating film, control panel control the opening and closing of relay from
And the working condition of Resistant heating film is controlled, and when the data that Temperature Humidity Sensor measures, which reach, hazes condition, relay
For closed, Resistant heating film is begun to warm up, and heating, which reaches, stops heating when being higher by about 15 DEG C than room temperature, and mirror surface is allowed to maintain
At this constant temperature threshold value.
Half mirror (also known as: atom mirror, single-surface mirror, single-lens reflex camera glass, Double sided mirror, one-way glass, two-way mirror), is one
Kind has the glass of very high reflectance to visible light.Light transmittance is greater than 84%, and with a thickness of 2~6MM, mirror surface shows that glass is non-lead
, touch membrane can be added.
Two-way mirror forms mirror effect in the case where display screen is closed without backlight, uses as mirror, display screen
Clearly picture image is appeared when unlatching.
Reflecting surface (mirror surface) must be side to light or towards outdoor side to half mirror when in use.When room is compared in outdoor
When interior bright, half mirror is similar to general mirror, and indoor scenery be can't see in outdoor, but interior can see outdoor clearly
Scenery.And when outdoor than it is indoor dim when, outdoor is and indoor it can be seen that outdoor scenery it can be seen that indoor scenery, clearly
Clear degree depends on the power of outdoor illumination.
For antifog, vapor can condense to the cold, and here it is the basic reason that bathroom mirror hazes, vapor encounters temperature
Low bathroom mirror is spent, condenses into one layer of water mist (droplet that can be understood as very little) on surface, surface is made to form diffusing reflection, nothing
Method is normally reflective, and causing can not normal use bathroom mirror.Shower water temperature is probably close with body temperature, between 35 DEG C -40 DEG C, bath
The surface temperature of room mirror also wants more slightly lower with respect to room temperature, wet air after biggish temperature difference+bathing, and bathroom mirror is caused to rise
Two necessary conditions of mist.Since the room temperature in winter is lower, the temperature difference of bathroom mirror and air is bigger, so the mist formed is also more
Dense, the time that mist dissipates naturally is also longer.By being embedded in Temperature Humidity Sensor in mirror, to mirror temperature, indoor humidity into
Row detection, carries out multiple Data Detection, obtains the critical value of a fogging, post one layer of electric heating behind finally by Anti-fog mirror
Antifog film, by heating wire film by electric energy Efficient Conversion be thermal energy, so that mirror surface is heated up, prevent condensation vapor from rising on mirror surface anti-
Mist effect.Additionally, it is preferred that also added a blowing apparatus in the upside of mirror, by reduce mirror around humidity prevent
Only mirror surface fogging.
Intelligent mirror possesses service for life, Infotainment, intelligent control, the big functional module of health control four, has human body
Incude, touch, interactive voice and intelligent control function, mirror, which is in, to close under screen state, when there is human body close to witch mirror, witch mirror meeting
It automatically turns on.Display Touch Screen below mirror carries " intelligent sound control " system, broadcasts from choosing, video, news
Full voice control can be realized to control household appliance, then to voice note message.
