Abstract
The present invention discloses a silencing device for dust collectors, which comprises an exhaust passage between a motor to an air outlet, wherein a silencing separator plate is arranged in the exhaust passage and is provided with a plurality of exhaust pipes. The silencing separator plate can form a tubular shape to improve the tortuosity of the exhaust passage to make acoustic energy lost in the transmission process, and accordingly, an effect of noise reduction can be achieved. The silencing separator plate can form a box shape to make wind volume changed when wind enters the box-shaped silencing separator plate, and accordingly, an effect of noise reduction can be achieved.
Description
Technical field
The present invention relates to a kind of noise absorption unit of dust collector.
Background technology
In the prior art, the basic structure of dust catcher is followed successively by suction port, dedusting chamber, motor machine, exhaust outlet, and exhaust outlet is lattice structure, its effect is only for preventing that foreign material from entering in the dust catcher body, and do not have sound deadening, therefore, the noise that common dust catcher sends in use is bigger, some high power vacuum cleaner particularly, noise is bigger.
Summary of the invention
The objective of the invention is: a kind of noise absorption unit of dust collector is provided, and this device is by installing silencing means at motor in the air-out passage of exhaust outlet, the noise when reducing dust catcher and using.
Technical scheme of the present invention is: a kind of noise absorption unit of dust collector, and the air-out passage between comprising from the motor to the exhaust outlet is provided with sound gobo in the described air-out passage, and sound gobo is provided with several exhaust ducts; Described exhaust outlet is positioned at the rear portion of motor, sound gobo is arranged between motor and the exhaust outlet, sound gobo is tubular construction, the opening of tubular sound gobo forward, back-end closure, sidewall is connected with shell of the dust collector around the tubular sound gobo, exhaust duct is distributed on the sidewall all around of tubular sound gobo, and the axis of exhaust duct is parallel with the axis of motor;
Insert in the opening of tubular sound gobo the rear portion of described motor.
The diameter of described exhaust duct is the 2-100 millimeter.
The length of described exhaust duct is the 5-500 millimeter.
Advantage of the present invention is:
1. the present invention is equipped with the tubular sound gobo in the air-out passage, and the tubular sound gobo is provided with discharge pipe, has increased the tortuosity of air-out passage, and the energy of sound wave is lost in communication process, thereby reaches the effect that reduces noise.
2. the present invention is equipped with the box-shaped sound gobo in the air-out passage, and the antetheca of box-shaped sound gobo is provided with exhaust duct, rear wall is provided with aperture, produces Volume Changes when making air-out enter the box-shaped sound gobo, thereby reaches the effect that reduces noise.
