Abstract
The utility model relates to a wind force air blower, and the structure is that, the gland is arranged at the top of semi-lunar windmill, the fixed support is arranged at the bottom, the baffle is arranged on the support, the semi-lunar windmill is connected with the transmission shaft through the upper and the lower connective pieces, then the air blower is arranged at the lower part of transmission shaft, and the bracket is arranged between the semi-lunar windmill and the fixed support; the transmission shaft is connected with the fixed support through the bearing and is connected with the semi-lunar windmill into a whole; then the semi-lunar windmill in rotation drives the rotation of transmission shaft under the efforts of natural wind, the transmission shaft drives the air blower to rotation for working; the utility model integrates the mechanical air exhaust and the natural air exhaust into a whole, mainly takes the mechanical air exhaust and increase the ability for air exhaust to exhaust air continuously, which guarantees the timely elimination of foul air indoor; the utility model has the advantages of being without manual energy and operation, no pollution to the environment, reverse intake proofing for outdoor air and rain water, being simple structure and convenient manufacture and is a sustainable environmental protection type air exhaust mechanics.
Description
Technical field
The utility model relates to a kind of air exhausting device, especially for the wind-force air bells exhauster.
Background technique
Air draft in the building at present, especially the air draft in residential housing kitchen and lavatory, mostly be to utilize the principle of natural exhaust to carry out, promptly utilize indoor and outdoor air density that indoor and outdoor air temperature difference causes different and air pressure difference that produce enters indoor vitiated air in the atmosphere.Natural exhaust since pressure reduction little, exhaust air rate is little, the air draft effect is generally bad, cause scurry between different floors kitchen and the lavatory flavor phenomenon very general.Simultaneously because exhaust port directly contacts with outdoor air, and when outdoor air pressure during greater than indoor air pressure, outdoor air can produce and pour in down a chimney, this moment is with regard to outwards air draft at all.Simultaneously, in wind and rain weather, rainwater also can pour in down a chimney in the inlet chamber sometimes.
On the demanding building of some clean level, generally by the electric power ventilating fan is installed, utilize mechanical exhaust to carry out the building air draft, though this mode has increased exhaust air rate, improved the air draft ability, also avoided exhaust port to contact substantially with the direct of outdoor air, but mechanical exhaust needs artificial control, consumed power, noise is big, and can not turn round continuously enduringly.
The existing pneumatic power air exhausting device such as the patent No. are the pneumatic power ventilation fan of (96238923.4).This pneumatic power ventilation fan has avoided exhaust port and the direct of outdoor air to contact by the semilune fan blade of rotation, has prevented pouring in down a chimney of outdoor air and rainwater, has guaranteed the natural pressure reduction that air exhaust channel itself is intrinsic, has improved the effect of air draft.On the air draft principle, this ventilation fan belongs to the category of natural exhaust, ventilation fan itself can not provide additional power for air draft, its effect is exactly the intrusion that prevents outdoor air, guarantee the air draft pressure reduction of indoor air, therefore, when a large amount of vitiated airs enters in the air exhaust channel, because air draft is limited in one's ability, it is still inevitable to scurry flavor between the kitchen of different floors and the lavatory.
Summary of the invention
For solving the deficiency of above-mentioned known technology, it is power with the natural wind that the purpose of this utility model is to provide a kind of, need not manual operation, the mechanical exhaust machine of air draft continuously.
The structural design of the utility model is achieved in that by critical pieces such as half-moon-shaped windmill, link, transmission shaft, bearing, air bells exhauster, carriage and fixed bearings forms (as shown in Figure 1).Its structure is, gland is equipped with at half-moon-shaped windmill top, fixed bearing is equipped with in the bottom, bearing is provided with baffle plate, fix by fixing bolt, half-moon-shaped windmill is by last, following link links to each other with transmission shaft, bottom at transmission shaft is equipped with blower fan, and half-moon-shaped windmill is fixed in by upper connector in transmission shaft top, and carriage is fixed in by following link in the bottom, transmission shaft and half-moon-shaped windmill are linked into an integrated entity, between half-moon-shaped windmill and fixed bearing carriage is housed, does not have bearing on the fixed support, transmission shaft links to each other with fixed support by bearing, blower fan can be a centrifugal fan, also can be axial fan.
Principle of the present utility model is on the basis of natural exhaust, is power with wind-force, drives air bells exhauster and carries out mechanical exhaust.Drive the transmission shaft rotation when half-moon-shaped windmill rotates under the wind-force effect, transmission shaft drives the blower fan rotary work by bearing, and the blast that relies on the blower fan rotary work to produce carries out air draft.
The utility model has following advantage compared with the prior art: dependence wind-force carries out mechanical exhaust and mechanical exhaust and natural exhaust technology is combined together, not only increased the air draft ability, and can continuously carry out air draft, guaranteed the timely eliminating of indoor vitiated air, in addition, the utility model also has without any need for the artificial energy source, need not manual operation, environment there is not any pollution, can prevent that outdoor air and rainwater from pouring in down a chimney to indoor, simple in structure, characteristics such as convenient processing and manufacture are a kind of environment protection type air draft machinery of sustainable use.
