Abstract
The utility model provides a noise-proof exhaust fan, which comprises a housing, at least two partitions, a fan and noise absorption layers, wherein the partitions are arranged in the housing in a staggered manner to form an S-shaped channel; a plurality of ventilation openings are formed in a front wall of the housing; the fan is arranged at the rear part of the housing; and the noise absorption layers are arranged on an inner wall of the housing and on the surfaces of the partitions. Compared with the existing exhaust fan, the exhaust fan has the advantage of good noise-proof effect, and is simpler in structure, easy to manufacture, and is suitable for offices and a houses with larger environmental noises.
Description
Technical field
The utility model relates to a kind of improved ventilation blower, and particularly a kind of sound insulation exhaust blower is suitable for the larger building of ambient noise and adopts.
Background technology
At present, the employed ventilation blower of office and family is ventilating fan, and existing ventilating fan does not have noise preventing device.Outdoor noise is easy to reach indoor, more especially near office building and the household of road, highway and factories and miness, will be subject to the severe jamming of noise.For this noise pollution, except closing outside window, there also do not have better way to prevent that outdoor noise from reaching through ventilating fan to be indoor.
Summary of the invention
The purpose of this utility model is to provide a kind of noise-proofing effective, sound insulation exhaust blower simple in structure for the problem of existing ventilating fan existence.
Task of the present utility model realizes by this way: this exhaust blower is comprised of housing, dividing plate, blower fan and sound absorbing layer, being not less than two dividing plates is crisscross arranged in housing and forms S shape passage, on the antetheca of housing, evenly have several ventilating openings, blower fan is arranged at the housing rear portion, is provided with sound absorbing layer on the surface of the full inwall of housing and dividing plate.
The utility model is like this work: this exhaust blower is contained on the wall of holding the hole successfully, allows blower fan and outdoor the connection get final product.When the startup blower fan carried out air draft, indoor air entered in the housing from the ventilating opening of inwall, through S shape passage, discharged outdoor finally by blower fan.From structure of the present utility model as can be known, outdoor noise must just pass to indoor through the aperture of S shape passage and inwall, sound helps large, can play certain deadening, add inner walls and baffle surface and all be provided with sound absorbing layer, its sound absorption further makes noise greatly weaken, and the utlity model has good noise-proofing function thereby make, and structure is comparatively simple, makes easily.
Description of drawings
Following structure accompanying drawing is further described structure of the present utility model.
Fig. 1 is front view of the present utility model.
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
The specific embodiment
Shown in accompanying drawing 1-2, a kind of sound insulation exhaust blower, formed by housing 1, dividing plate 2, blower fan 3 and sound absorbing layer 4, being no less than two dividing plates 2 is crisscross arranged in housing 1 interior formation S shape passage, on the antetheca of housing, evenly have several ventilating openings 5, blower fan 3 is arranged at housing 1 rear portion, is provided with sound absorbing layer 4 on the surface of housing 1 inwall and dividing plate 2.This housing 1 is made with sheet metal or plastics, and dividing plate 2 is comparatively suitable with 2-6, is preferably 4, and too much windage is larger, affects the air draft effect; Noise-proofing weak effect when too small.Several ventilating openings 5 of opening at housing 1 antetheca can adopt the ventilating opening of various shapes or form, are 2～5 millimeters aperture but preferably adopt diameter, utilize the aperture sound deadening further to reduce noise.The blower fan 3 that is arranged on housing 1 rear portion is preferably disposed on housing 1 rear end and is exposed on the outer sidewall of wall, can avoid outside noise directly to reach in the housing 1, helps importing into of noise reduction.The sound absorbing layer 4 of being located at housing 1 inwall and dividing plate 2 surfaces can adopt sponge, staple fibre felt or glass mat.
The office building that the most suitable environmental noise of the utility model is larger and house use.
