The utility model discloses a kind of fresh air purifiers with decrease of noise functions, it includes casing, casing internal is air duct, wind turbine is equipped in air duct, the open end in air duct is air outlet, at least one denoiser is equipped between air outlet and wind turbine, denoiser setting is arranged in filter screen bottom, strainer at air outlet.The utility model adds at least one denoiser in air duct, the position that denoiser is placed is after the wind turbine as noise source, and at 3 10cm of wind turbine rear end, the front of denoiser is signal microphone, signal microphone collects and surveys the phase and amplitude of noise towards noise source;The reverse side of denoiser is HIFI loudspeaker, HIFI horn launch sound wave identical with sound of the wind noise opposite in phase, amplitude, the placement direction of denoiser and air-out direction keeping parallelism, denoiser generates the positive sound wave that reversed sound wave is generated with machine wind turbine itself rotation and neutralizes, final sound reduces, and has the function that noise reduction.

Description

A kind of fresh air purifier with decrease of noise functions
Technical field
The utility model is related to fresh air purification device field more particularly to a kind of fresh air purifiers with decrease of noise functions.
Background technology
New wind turbine inhales fresh air from outdoor, preset filter screen in complete machine of arranging in pairs or groups, and realizes indoor filtering and promotion contains The purpose of oxygen amount.New wind turbine, due to there is wind turbine rotation to generate air quantity cycle, noise problem is also adjoint, in order to increase Air quantity, it is often necessary to expanded motor rotating speed, after motor accelerates, noise problem meeting household, or use and increase blower fan volume specification, Product appearance size can be made to increase.Therefore, it is necessary on fresh air purifier technological layer, reduce noise.
Utility model content
It is net in fresh air the technical problem to be solved by the present invention is to provide a kind of fresh air purifier with decrease of noise functions Change and add Sound Processor Unit in device, Sound Processor Unit generates the positive sound wave that reversed sound wave is generated with machine wind turbine itself rotation and protects It holds generation part to neutralize, finally reduces noise.
In order to solve the above-mentioned technical problem, the utility model provides a kind of fresh air purifier with decrease of noise functions, Including casing, the casing internal is air duct, and wind turbine is equipped in the air duct, and the open end in the air duct is air outlet, At least one denoiser is equipped between the air outlet and the wind turbine, the denoiser is arranged in filter screen bottom, the strainer It is arranged at the air outlet.
Preferably, the denoiser includes signal microphone and HIFI loudspeaker.
Preferably, the signal microphone setting is in the nearly fan end, and the HIFI loudspeaker setting is in the nearly outlet air Mouth end.
Preferably, the area of section of the closely described fan end of the denoiser is less than the section face of its nearly air opening end Product.
Preferably, the placement direction of the denoiser is parallel with air-out direction.
Preferably, the denoiser is 3-10cm with a distance from the wind turbine.
Preferably, exhausting plate is equipped at the air outlet, the exhausting plate is equipped with several exhaust vents.
Preferably, the exhaust vent is arranged in arrays on the exhausting plate.
The technique effect of the utility model:
The utility model adds at least one denoiser in air duct, and the position that denoiser is placed is in the wind turbine as noise source Later, at the 3-10cm of wind turbine rear end, the front of denoiser is signal microphone, and signal microphone is collected and divided towards noise source Analyse the phase and amplitude of noise;The reverse side of denoiser is HIFI loudspeaker, HIFI horn launch and sound of the wind noise opposite in phase, amplitude Identical sound wave, placement direction and the air-out direction keeping parallelism of denoiser, denoiser generate reversed sound wave and machine wind turbine certainly The positive sound wave that body rotation generates neutralizes, and final sound reduces, and has the function that noise reduction.
