Abstract
The utility model discloses a low noise aspirator, comprising the front shell and the back shell of the aspirator, an electric blower arranged in the back shell, the fixing clip of the electric blower, the seal ring of the electric blower and an air duct outlet at the bottom of the back shell. The low noise aspirator is characterized in that noise release positions in the outer part of the electric blower and the inner parts of the front shell and the back shell are provided with a plurality of noise reduction rings and noise reduction pads, and the air duct outlet at the bottom of the back shell is added with a plurality of small holes. The utility model has the advantages of simple design, convenient operation, low cost for reducing noise and favorable effect on reducing noise, original die is not changed, materials for reducing noise are easy to be obtained, and important assurance is provided for opening a way to the market for the product.
Description
The utility model belongs to a kind of noise reduction dust catcher that can reduce noise when using.
At present, two blower fans on the domestic market, the slow-speed of revolution, high power vacuum cleaner, its design route is more reasonable than original single-unit high-speed fan dust catcher, so result of use is good, but the also common high major defect of noise that exists of such dust catcher, not good enough and materials and intrinsic difference of technology makes noise bigger to making us insufferable stage in addition, consequently has influence on the sale of product.Such dust collector structure generally is by forward and backward shell, place electric fan and fixing card thereof in the back cover, the electric fan sealing ring is formed, the back cover bottom is a ducting outlet, the vibrations that electric fan is worked betwixt, produced be undoubtedly big and noise too open, so cause the disadvantage of too noisy in the dust catcher use.
The purpose of this utility model is to install additional some noise abatement facilities on original dust catcher, make it to become a kind of noise reduction dust catcher, such average noise abatement of stepless time adjustment dust catcher through about the 800W behind the noise reduction can reach the 8-10 decibel, make many substandard products up to standard, tangible economic benefit and social benefit will be arranged.
The technical solution of the utility model: a kind of noise reduction dust catcher, comprise dust catcher fore shell, back cover, place the electric fan in the back cover and the ducting outlet of fixing card, electric fan sealing ring and back cover bottom thereof, the noise release position that it is characterized in that and forward and backward shell inside outside at said electric fan is provided with multiple tracks noise abatement circle and noise abatement pad, and the ducting outlet portion in the back cover bottom increases a plurality of apertures.The said position that the noise abatement circle is set can be electric fan shell and fore shell inwall, the said position that the noise abatement pad is set can be electric fan and sealing ring joint, forward and backward shell junction, the ducting outlet inwall place of electric fan lead place back cover side-walls and back cover, said ducting outlet aperture that portion increases in the back cover bottom, its quantity can be 30-80, and its aperture can be 10mm-4mm.
Operation principle of the present utility model: be provided with at the above-mentioned variant position of dust catcher subtract circle falls, pad is to determine according to the noise frequency at each position of machine and noise intensity difference, on ducting outlet, increase aperture, except that eliminating the noise, still can reduce windage, the dust catcher noise is a kind of reverberation noise of many sound sources multiport, so aforesaid way is a kind of design of making an uproar that removes at suiting measures to local conditions of taking of dust catcher noise behavior.
Superiority of the present utility model: 1, simplicity of design, need not change original mould, so every only average adding cost 2-3 unit, it is convenient to implement, and deadener is desirable easily; 2, excellent noise reduction effect, treated good dust catcher, noise is quite low, and frequency content mainly is distributed in the low-frequency range lower to human body harm, and no high frequency is uttered long and high-pitched sounds, and provides important assurance so open up markets for product.
Further specify present technique below in conjunction with drawings and Examples.
Accompanying drawing 1 is the related noise reduction dust collector structure of a utility model schematic diagram.
Wherein 1 is electric fan, and 2 is A noise abatement circle, and 3 is screw, and 4 are fixing card, and 5 is B noise abatement circle, 6 is A noise abatement pad, and 7 is sealing ring, and 8 is fore shell, and 9 is C noise abatement circle, and 10 is B noise abatement pad, 11 is C noise abatement pad, and 12 is D noise abatement pad, and 13 is back cover, 14 apertures for the increase of ducting outlet portion.
Accompanying drawing 2 is original dust collector structure schematic diagram.
Wherein 15 is former ducting outlet hole.
Embodiment: a kind of noise reduction dust catcher (see figure 2) comprises dust catcher fore shell 8, back cover 13, places the ducting outlet hole 15 of the electric fan 1 in the back cover and the fixedly card of fixing with screw 34, electric fan sealing ring 7 and back cover bottom, it is characterized in that (see figure 1) noise release position outside at said electric fan and forward and backward shell inside is provided with multiple tracks noise abatement circle and noise abatement pad, the ducting outlet in the back cover bottom increases a plurality of apertures.The said position that the noise abatement circle is set can be the C noise abatement circle 9 on A noise abatement circle 2 and B noise abatement circle 5 and the fore shell inwall on the electric fan shell; The said position that the noise abatement pad is set can be the A noise abatement pad 6 of electric fan 1 and sealing ring 7 joints, the B noise abatement pad 10 of forward and backward shell junction, the D noise abatement pad 12 at the C noise abatement pad 11 of electric fan lead place back cover side-walls and the ducting outlet inwall place of back cover; 60 of the apertures that said ducting outlet increase aperture in the back cover bottom is 5mm.
Claims (4)
1, a kind of noise reduction dust catcher, comprise dust catcher fore shell, back cover, place electric fan and fixing card thereof in the back cover, the ducting outlet of electric fan sealing ring and back cover bottom, the noise release position that it is characterized in that and forward and backward shell inside outside at said electric fan is provided with multiple tracks noise abatement circle and noise abatement pad, and the ducting outlet portion in the back cover bottom increases a plurality of apertures.
2, by the said dust catcher of claim 1, it is characterized in that the said noise abatement circle position that is provided with can be electric fan shell and fore shell inwall place.
