Description

A kind of light-operated louver
Technical field
The present invention relates to a kind of dedusting and purifying air technical fields.
Background technology
In order to purify indoor air, most of families can usually select purchase air purifier to improve indoor air Quality.But air purifier causes air to be difficult to circulate, be easy to cause secondary dirt instead generally in the indoor use of closing Dye.Secondly, air purifier can occupy the interior space of a part.At present, existing window is mainly made of window frame and sash. Window has windowpane, screen window, plate window and blind window etc..Take shelter from rain with keeping out the wind, sunshade sound insulation, protection indoor occupant to from The effect that extraneous factor is invaded and harassed.But window at present on the market all there are it is certain the defects of:Common screen window can not stop outer The suspended particulate substance and pernicious gas in portion etc. can not purify air, ensure indoor air quality.Windowpane can not be according to interior chamber Light regulating light and shade is inside needed, to reach indoor illumination requirements.Shutter aggravates significantly mostly using manually controlling The workload of labourer.And manual operation shutter is easier to damage, and reduces the service life of shutter.
According to retrieval, the Chinese patent application of Publication No. CN204899720U discloses a kind of solar energy light-operated louver control Device processed, including:Microprocessor, illumination detection array module, driving stepper motor module, illumination display module, photovoltaic electric power storage Pond charge-discharge modules and machine control modules, wherein, indoor light intensity signal is converted into voltage signal by illumination detection array, is led to The light intensity signal crossed in the accurate measuring environment of inside analog-to-digital conversion of microprocessor simultaneously passes through illumination display module and shows, and carries out PWM according to different light intensity signals, the pulse of PWM output different duties and modulating frequency, and then controls driving stepper motor mould Block realizes the opening and closing angle and closure of illumination control shutter, makes indoor illumination intensity is moderate to maintain in a critical field.
For another example the Chinese patent application of publication number CN102587809A disclose a kind of solar power generation air-conditioning shutter and Application method is included in fixing spool in aluminium alloy upper beam, and motor and reel, reel and electricity are installed on spool Machine connects, and messenger wire is connected on reel, and the following of reel has aluminum alloy rail, and messenger wire is located in aluminum alloy rail;In aluminium Accumulator group, control circuit board and output socket, accumulator group, control circuit board and output socket are installed in alloy upper beam Respectively by connection;Circular hole is fixed with slide bar among aluminium alloy vane, and slide bar is connected on messenger wire;Aluminium alloy vane is arc There are heat absorbing coating in shape, the concave surface of aluminium alloy vane, and solar power generation film is bonded on convex surface.
In place of the equal Shortcomings of technical solution that above two controls solar energy light-operated louver, the first technical solution Device the folding of shutter can only be adjusted, can not accomplish the outer toxic and harmful gas of isolating chamber, second of technical solution Device can not accomplish according to indoor light automatically adjust shutter opening and closing, it is necessary to labor intensive is adjusted, cause Certain inconvenience.
