Abstract
The invention discloses a noise reduction device with the function of changing a sound transmission track, which comprises three gear-shaped sound attenuation plates. The sound attenuation plates are three round ring devices with eight notches; and the notches of the three round ring devices are over against bumps to be arranged side by side in an air flowing bin for wind discharged by a dust collector in a staggered manner. In the using process of the noise reduction device, when passing through three silencers, the wind can flow along the notches of the three gear-shaped sound attenuation plates, so that the travel path of wind sound is changed and the sound makes more turns in the dust collector, so as to achieve the aim of reducing the noise. The noise reduction device has the benefits of simple structure, reasonable construction, low cost and capability of reducing excessively high noise of the dust collector in the using process and reducing damage of the noise to human bodies.
Description
Technical field the present invention relates to noise reduction system field in the life, relates to specifically a kind of device of realizing the noise reduction purpose by changing the sound transmission track.
Background technology is along with the improve of people's living standard, dust catcher has been come into huge numbers of families, but existing dust catcher is the excessive phenomenon of ubiquity noise in use, excessive noise can produce harm to human body, and at present a kind of effective and feasible dust catcher denoising device is arranged not yet, can not satisfy people's use needs.
Summary of the invention the purpose of this invention is to provide a kind of denoising device that changes the sound transmission track, realizes that sound reduces noise in communication process, to solve existing dust catcher noise problems of too.
The present invention includes three plate gear shape acoustical panels, described acoustical panel is three circle ring devices that have eight recesses, and with their recess facing in the tang Air Flow storehouse that is installed in side by side the dust catcher air-out straggly.
During use, walk out-of-dately from three silencing means when wind, wind can flow along the recess of three gear-like acoustical panels, so just changes the propagation path of sound of the wind, and it is several curved that enable voice turns in dust catcher more, reaches the purpose of reduction noise with this.
Beneficial effect of the present invention is: simple in structure, structure rationally, and is cheap, can reduce dust catcher excessive noise in use, reduces noise to the harm of human body.
Description of drawings Fig. 1 is the front view of acoustical panel one of the present invention.
Fig. 2 is the top view of acoustical panel of the present invention.
Fig. 3 is structural representation of the present invention.
Reference numeral: 1-1 is acoustical panel one, 1-2 is acoustical panel two, and 1-3 is that acoustical panel three, 2 is the recess of acoustical panel, 3 is the tang of acoustical panel, 4 is the Air Flow storehouse, and 5 is wind, and 6 is the dust catcher air entry, 7 is dust catcher air entry place venthole, 8 is motor, and 9 is motor place venthole, and 10 is dust catcher afterbody venthole.
The specific embodiment is in the schematic diagram of the denoising device of Fig. 1 change sound transmission track extremely shown in Figure 3, comprise three plate gear shape acoustical panels, acoustical panel is three circle ring devices that have eight recesses 2, and with their recess facing in the tang 3 Air Flow storehouse that is installed in side by side the dust catcher air-out straggly.During use, the recess of three acoustical panels facing in the tang Air Flow storehouse 4 that is installed in side by side the dust catcher air-out straggly, is formed a noise-reducing structure.Wind 5 sucks from air entry 6, enter into air entry place venthole 7 and flow direction motor 8, then wind flows out in the Air Flow storehouse 4 from motor venthole 9, at this moment, wind can flow to annular tooth colyliform acoustical panel two 1-2 through stopping respectively from its eight recesses 2 of annular tooth colyliform acoustical panel three 1-3, can pass through stopping of acoustical panel two again forward, wind will be at acoustical panel two, place between three is turned individual curved, flow to annular tooth colyliform acoustical panel one 1-1 from eight recesses 2 of annular tooth colyliform acoustical panel two, this moment is stopping through acoustical panel one again, wind can turn individual curved between acoustical panel one and acoustical panel two, flow to afterbody venthole 10 from eight recesses 2 of annular tooth colyliform acoustical panel one, turning that again can be is once finally flowed out from the afterbody venthole.By changing the propagation path of sound of the wind, it is several curved that enable voice turns in dust catcher more like this, just can reach the purpose that reduces noise.
