The utility model in view of the deficiencies of the prior art, proposes a kind of effective compression for reducing mobile external counterpulsation apparatus On the one hand the noise reduction system of machine noise can reduce the vibrations because of compressor, on the other hand can reduce compressor electric motor production The propagation of raw noise, while being also reduced in the noise of air inlet, specific technical solution is as follows：

A kind of movable type external counterpulsation apparatus noise reduction system, including compressor and separate cavities, the compressor are placed in described In separate cavities；

The separate cavities include bottom plate, side plate and top plate, the upper surface of the bottom plate, the inner wall of the side plate and the top The lower surface of plate is equipped with sound absorbing layer；

The compressor is mounted on the bottom plate, dampening assembly is additionally provided on the bottom plate, the dampening assembly is located at Between the bottom plate and the compressor；

The work air intake pipe orifice and work air outlet tube mouth of the compressor are arranged on top plate, the work air intake pipe orifice Air cleaner is installed.

By the way that compressor is isolated so that the noise of compressor is not easy Spreading and diffusion, while by separate cavities Inner wall sets up sound absorbing layer, has further achieved the effect that noise reduction, passes through the setting of dampening assembly so that the shake that compressor generates Dynamic noise is reduced, and by the effect of air cleaner, has on the one hand achieved the purpose that cross air filtering, on the other hand so that air Into fashionable, entered by multiple tiny holes, air is reduced into fashionable noise.

It further limits, the sound absorbing layer is acoustical cotton.

Acoustical cotton it is light-weight, the mobility of entire external counterpulsation device is good.

It further limits, the dampening assembly includes support plate and shock-absorbing leg, the shock-absorbing leg and the support plate It is fixedly connected, the compressor is mounted in the support plate.

Support plate and shock-absorbing leg cooperation, can be effectively hanging, improves damping effect, the structure of support plate facilitates pressure The installation of contracting machine.

It further limits, the shock-absorbing leg is made of elastic rubber, and the upper and lower end face of the shock-absorbing leg is embedded with Nut.

Embedded nut structure effect is, when shock-absorbing leg is fixedly mounted, upper and lower ends respectively with a bolt into Row cooperation is fixed, easy to assembly, and repair and replacement are also convenient for.

It further limits, the length of the shock-absorbing leg is 25mm-35mm.

Mobile external counterpulsation device, it is desirable that it is small, therefore the length of shock-absorbing leg cannot be too big.

It further limits, the side plate is equipped with cooling air inlet, also is provided on the inner wall of the cooling air inlet described Sound absorbing layer.

The noise in separate cavities is reduced from cooling air inlet diffusion.

It further limiting, wind shield is equipped at the cooling air inlet, the wind shield is suspended vacantly on the side plate, Cooling air inlet described in the wind shield face, has interval between the wind shield and the cooling air inlet.

The effect of wind shield is, avoids when wind is from cooling air inlet into fashionable, generating big noise, have wind shield with Afterwards, wind can enter from the side of wind shield, and for entering from front, side is lower into fashionable noise.

The beneficial effects of the utility model are：Compressor is isolated by separate cavities, carries out preliminary noise reduction, by Sound absorbing layer is set on the inner wall of separate cavities, further carries out noise reduction, sound absorbing layer then is set on the inner wall of cooling air inlet, is subtracted On the one hand few noise diffusion from cooling air inlet has also achieved the effect that reducing noise spreads by setting up for wind shield, On the other hand, the noise for reducing air circulation generation, passes through the setting of dampening assembly so that the vibrating noise of compressor drops It is low.
