A kind of active ventilation screen window of isolating PM2.5
Technical field
The present invention relates to a kind of ventilation screen window, particularly relate to the active ventilation screen window of a kind of PM2.5 of isolation.
Background technology
We are made by stainless steel gauze by the window frame of known house window screening at present, are arranged on the inner side of house glass window, when we open the window, and the effect of playing certain ventilation and preventing some mosquitoes along with the energy of flow of outside air.But due to for the larger area of dust as the north, because this kind of window screening emptying aperture is larger, cannot prevent airborne dust, but if window screening Tai Mitai is tight, can affect again ventilated.
Application number is that 200720115858.8 Chinese patents have proposed a kind of high density dust-proof window screen, by multiple tracks anyhow cross arrangement form framework and which is provided with one deck high density gauze, framework and gauze combine as a whole.Its compact conformation, lightweight, more traditional stainless steel window screening, can guarantee, in ventilated situation, can also effectively prevent outside air dust and micro-worm.
Application number is that 200520106751.8 Chinese patents are to propose a Novel window screen that utilizes electrostatic absorption principle.Nonwoven with static is compressed in non-conductive gauze substrate, forms screen pack, utilize electrostatic adsorption to carry out purification filtering to entering indoor air.Can effectively reduce dust pollution in Urban House.
Application number is that 200820003417.3 Chinese patents are to propose a kind of active ventilation type screen window of small fan that adds.At two parts up and down of its master window frame, many small-sized fanses are respectively installed, then are covered air insulated plate between upper and lower fan, by an outdoor side, high-density air screen pack is installed.Rely on fan effect initiatively to carry out indoor and outdoor ventilation, and rely on high density filter net to carry out anti-dust.Although yet first two window screening can prevent the dust in micro-worm and outside air well, can not carry out initiatively indoor and outdoor ventilation for the first, the second window screening is can not play the effect of ventilation completely, but also affects daylighting.And the third active ventilation screen window is satisfied dustproof, and can take a breath on one's own initiative.But structure is comparatively complicated, and whole screen window thickness is larger, and I think that it is to have wasted that high density filter net has more part.
Summary of the invention
In order to overcome the comparatively complicated problem with waste of material of active air hole knot structure, guaranteeing, on the indoor basis that can well take a breath, to improve stock utilization, improve daylighting, simplify screen window overall structure.
The present invention proposes the active ventilation screen window of an improved isolation PM2.5.Technical scheme is as follows: first at master window frame, respectively add up and down the fixed support that can place several (determining according to screen window size) small fans, then can interval in these supports certain width one centimetre of a thickness, length and width are installed is the small fan of 10 centimetres * 10 centimetres, be similar to computer CPU radiator fan, upper and lower small fan respectively embeds a slice high-density air screen pack or high density filter cotton (depending on air ambient) by an outdoor side, and its width is identical with the height of small fan.Between upper and lower fan, put into an indoor-outdoor air insulating glass.The effect that so just can lean on small fan blows to the air after filtering indoor, plays the effect to indoor air-changing.
This advantage is: simplified the structure of screen window, the use after be more convenient for engineering construction and user.The consumption that has reduced high-density air screen pack or the many filter pulps of high-density air, it has improved the utilization rate of material, and daylighting is better.Can also effectively prevent that outdoor dust and micro-worm from entering indoor when carrying out good ventilation ventilation to indoor.

The specific embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims to the modification of the various equivalent form of values of the present invention and limit.
Embodiment
First small fan is installed on the upper and lower fan Fixture of master window frame.Then at upper and lower small fan, lean on an outdoor side, high-density air screen pack is inserted into respectively in master window frame and support bracket fastened slot.Finally on master window frame, need the place engaging with glass division board to coat appropriate fluid sealant, then glass division board is installed on master window frame.Screen window main body installs.
Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should belong to the behavior of invading the scope of protection of the invention.In every case be the content that does not depart from technical solution of the present invention, any type of simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
