Abstract

The utility model relates to air purifying screen windows and doors making use of static electricity to purify the air entering and going out of a room. The utility model is mainly composed of an insulated frame and a wire gauze, especially the wire gauze has multiple layers. The wire gauze is connected with a DC static electricity power supply. The utility model makes use of the static electricity to purify the air entering the room and has the advantages of good dust removing effect, no noise and simple and practical structure.

Description

The air purification screen window and door

The utility model relates to a kind of screen window and door, is a kind of air purification screen window and door capable of purifying air specifically.

Now screen door, the screen window function on the door and window that generally uses is more single, and form is dull, just in order to prevent in the inlet chamber such as mosquito, and not other effects, and only take form of single sheet on the structure, not too many variation.

At present, popular indoor air cleaner on the domestic and international market though can partly improve IAQ (indoor air quality), because of its starting point is confined to indoor air purification on the simple meaning fully, and has been ignored the flowability that air had, so there are many weak points.At first, this kind clarifier can be described as a kind of method of curing the symptoms, not the disease of passivity, that is to say that using this kind air purifier is that, occupants contaminated at room air sucked under the situation of pernicious gas, closes the doors and windows to purify.And the indoor air time that has purified is long slightly, will lose freshness, and need door and window again this moment again, puts outdoor air into and purify again, go round and begin again, so, may not purify the air of a room fully, guarantee air quality.Secondly, this kind indoor air cleaner area is limited.Modern Family's chamber structure is comparatively complicated, and existing parlor, bedroom, dining room have the washroom again, storage room or the like.So one family is subjected to the restriction of indoor air convection if place an air purifier, can not to have living space and thoroughly purify, can not everyday start for a long time simultaneously.The 3rd, this kind air purifier can be produced certain noise, and the bedroom that influences human body occupies and rest.The 4th, cost is higher.

The purpose of this utility model is to provide a kind of air purification screen window and door that purifies the turnover room air, and airborne suspended particulate substance is adsorbed on the screen window and door.

The utility model is achieved in that

The air purification screen window and door mainly is made up of insulating frame and wire gauze, and wire gauze is fixed on the insulating frame, it is characterized in that: described wire gauze be two-layer or two-layer more than, leave a fixed gap between every layer; An also external dc static power supply on this wire gauze, making wire gauze outer is that positive pole, internal layer are negative pole.

After the utility model adopts above structure, owing on wire gauze, be associated with high voltage direct current, on wire gauze, produce static, to the udst separation of going ahead of the rest of the air in the inlet chamber, can remove the hazardous substances more than 95% in the air, and not produce noise, have simple and practical, dust removing effects is obvious, the effect that cost is low.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the circuit diagram of the utility model power unit;

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

In the accompanying drawing, 1 is wire gauze, and 2 is insulating frame, and 3 is the power supply wiring point.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model air purification screen window and door mainly comprises wire gauze 1, insulating frame 2 and external dc static power supply, and wire gauze 1 is fixed on the insulating frame 2, and this insulating frame 2 can be installed on the door and window.Described wire gauze 1 be two-layer or two-layer more than, leave a fixed gap between every layer.Wire gauze 1 links with the dc static power supply.

Wire gauze 1 is made of two-layer, and the distance between two-layer is greatly about about 4cm.Insulating frame that double layer of metal silk screen 1 links 2 is made by insulating bodies, as duroplasts, rubber, plastic-steel etc.This wire gauze 1 is made by the wire of 0.05mm, considers cost, is advisable with galvanized wire.The gauze hole generally is good between 0.02mm-1mm.So neither the influence ventilation is bright, also can ensure the effect of dedusting.Can increase or reduce if any the special requirement mesh.Then, on double-level-metal silk screen 1 bottom and top insulating frame 2, groove is set, the fixing tongue made from insulation plastic-steel material on original window frame.Insulating frame 2 is embedded in the tongue, can left and right sides push-and-pull so that make it.For safety, alternating floor insulation materials between want insulating frame 2 and original door and window anastomosis, and more than the preferably outstanding 10cm, in order to avoid make electrostatic leakage.For casement window, connect the frame part and will give prominence to more than the 50cm, its projection also can be made double-deck silk screen, in order to circulation of air.This wire gauze 1 links by two power supply wiring points 3 and external dc static power supply.

As shown in Figure 3, transistor BG and winding coil L ₁, L ₂Deng forming high-frequency oscillating circuits, through high-frequency and high-voltage device B coupling, L ₃After winding boosted, by high pressure silicon grain D rectification, high-voltage capacitance C filtering obtained high pressure at the capacitor C two ends, and high pressure range is the 8000-10000 volt.Power supply can adopt solar opto-electronic board E ₁Make power supply, No. five Ni-Cd nickel-cadmiums of three joints in parallel are simultaneously made standby electric power E ₂When fine, solar opto-electronic board E ₁For wire gauze 1 charging, when sunshine is not enough, is used in battery and makes standby electric power.Because the high-tension current of output is minimum, so can not cause dangerous.

During use, the low-voltage dc power supply that power supply provides produces about 9 kilovolts high pressure after boosting, and the positive pole of this high voltage source is inserted the skin of wire gauzes 1 by power supply wiring point 3, and negative pole is received the internal layer of wire gauze 1.Like this, just between two-layer, form a stronger electric field, and near more apart from negative pole (nexine screen window), and electric field is strong more.When outdoor air is flowed through wire gauze 1, is electronics and cation near near the air molecule the nexine net by electric field ionization, cation is gone on the nexine gauze and is obtained electronics, become air molecule again, electronics marches on towards in the process of outer gauze (positive pole), and suspended particulate substance in the contaminated air or the like pernicious gas then can be electronegative, be adsorbed on the outer gauze (positive pole), the air that is cleaned then can flow into indoor smoothly.
