Description
Technical field
The present invention relates to building consumptive material technical field, i.e. a kind of ventilation shaft air outlet outer cover, dust-proof mainly for ventilation shaft, purification.
Background technology
In recent years, national industrialized level promoted rapidly, and science and technology is progress constantly, but what bring while industrialization development is the decline of quality of air environment, various places sandstorm and haze happen occasionally, and air pollution is serious, and air pollution has become the major issue threatening health of people.
The small-sized clarifier of family and office space emerges in an endless stream, but contemporary building or larger office place are all had to self ventilation shaft or central air-conditioning wind pipe, because these facility inner ventilation covers are all simple to filter or in line, in outside air, all-pervasive various harmful substance just " stealthily slips into " by ventilation shaft or central air-conditioning pipe and accumulates and grows, and threatens the life and health of people.Such as: China Patent No. CN204593735U, title: a kind of ventilation shaft can changing filter screen, this device is in ventilation shaft, add one deck screen pack, the gas of pipeline is simply filtered, but this filter effect is difficult to reach perfect condition, the filter screen of Long-Time Service easily results in blockage, and affects ventilation effect and not easy to clean, the words changed can increase maintenance cost again, lose more than gain.
Therefore, the present invention makes just in view of the above problems, the object of the present invention is to provide a kind of ventilation shaft air outlet outer cover, and it in very easily detachable situation, can reach ventilation shaft or the central air-conditioning wind pipe of ideal filter effect.
Summary of the invention
Therefore, the present invention makes just in view of the above problems, the object of the present invention is to provide a kind of automatic air purifier, manufacture and provide a kind of purifier that is safe, the air ambient of family and Administrative Area indoor easily under the very cheap prerequisite of maintenance cost.
According to technical scheme of the present invention, above-mentioned object can by providing a kind of ventilation shaft air outlet outer cover, described ventilation shaft air outlet outer cover comprises: fasten outer cover, turning cylinder, rolling bearing, air blade, filtering net surface, bracket, it is detachable for fastening outer cover, 4 piecemeals can be splitted into, the two ends of turning cylinder are fastened on respectively and fasten on outer cover, rolling bearing fixes on the rotating shaft, filtering net surface is fixed on the rotating shaft, the material of filtering net surface easily produces the material that also can store electrostatic, such as TPE material, a large amount of electrostatic can be produced at the friction lower filter screen of air current flow, air blade is fixed on rolling bearing, air blade can drive rolling bearing to rotate on the rotating shaft, the material of air blade easily produces the material that also can store electrostatic, such as TPE material, air blade rotates in atmosphere and can produce a large amount of electrostatic with during windage, former and later two faces of filtering net surface arrange an air blade respectively, the shape of air blade is the spiral-shaped of electric fan, and the spiral-shaped of two air blades is contrary, the direction that two air blades rotate in ventilation shaft or air-conditioner air outlet is also contrary, bracket is fixed on the support of air blade periphery, bracket can facilitate in use puts into ventilation shaft or central air-conditioning pipe by whole device.
The present invention adds friction-type electrostatic precipitator at ventilation duct road junction or air outlet of air conditioner duct, a large amount of electrostatic charge can be produced, effectively can stop entering of the harmful suspended particle in the air such as bacterium, dust, the cleaning of ventilation shaft and air-conditioner air outlet is played a significant role, to improving the quality that we suck air, electrostatic also can prevent the insect such as mosquito and mouse from entering pipeline, causes line clogging or pollution; Structure of the present invention is very simple, operation and easy to maintenance, and manufacturing cost is very cheap, is applicable to ventilation shaft and the central air-conditioning pipe of all kinds of corridor.
Accompanying drawing explanation
Fig. 1 is front air blade front view.
Fig. 2 is lateral plan of the present invention.
As shown in Figure 2: 1 fastens outer cover, 2 air blade 1-1,3 air blade 1-2,4 turning cylinders, 5 rolling bearings, 6 filtering net surface, 7 brackets.
Detailed description of the invention
Now, the preferred embodiments of the present invention will be described in detail by reference to accompanying drawing, easily realize these embodiments like this for the people in the existing technical staff of field that the present invention belongs to ordinary skill.But the present invention also can various different form realize, and therefore the invention is not restricted to the embodiment hereinafter described.
As illustrated with reference to fig. 2, as required in advance can according to the specifications design of ventilation shaft by the size fastening outer cover 1(fastening outer cover 1, fastening outer cover 1 can be removed by circular ventilating opening or air outlet, fastening outer cover 1 can be installed by square ventilating opening or air outlet), can continue to use after rear cleaning for convenience detach after long-time use.During use, bracket 7 can be carried by people and whole device put into ventilation shaft or air conditioning exhausting pipeline, because the present invention is provided with two air blades (1-1,1-2), so no matter wind enters in pipeline or goes out, the rotation of air blade 1-1 or 1-2 all can be driven.When air enters pipeline from pipeline, outside air blade 1-1 rotates under air mobilization, because air blade 1-1 is TPE material, a large amount of electrostatic can be produced when rotating in atmosphere, the electric charge producing electrostatic is negative electrical charge, with the electrically charged homopolarity of harmful suspended particulate substance in air, the generation effect of repelling each other, air blade 1-1 in rotation will form one deck electrostatic air-curtain, harmful suspended particulate substance is stoped to enter, the fresh air tentatively filtered through air blade 1-1 continues to flow to filtering net surface 6, when fresh air flows to filtering net surface 6, produce with filtering net surface 6 and rub, because filtering net surface 6 is also TPE material, also a large amount of electrostatic can be produced with during windage, harmful suspended particulate substance in air is accomplished that second time is filtered, filter effect will be greatly improved, and the fresh air flowing through filtering net surface 6 will flow to air blade 1-2, because air blade 1-2 is what be inverted, so, air blade 1-2 also can automatic rotation, form third layer electrostatic air-curtain, a step improves filter effect again, the rotation of air blade 1-2 also accelerates air velocity further, make air and two air blade (1-1, 1-2) more violent with the friction of filtering net surface, the effect producing electrostatic is more obvious.Otherwise the working method of air outlet is also like this.
The air inlet of ventilation shaft or central air-conditioning pipe and air outlet can be placed apparatus of the present invention respectively, so just can ensureing that ventilation shaft cleaning is free of contamination while, avoid harmful suspended particulate outside building to flow in building, in building, fresh air also can not flow to outside building.
