Description
Technical field
The present invention relates to a kind of silencers.
Background technique
A large amount of noises can be generated during fan operation, current existing silencer is in cylindric shell mostly
Sound-absorbing material is set, and structure is simple, construction is single, it is poor to absorb sound wave effect, and be not easily cleaned the ash accumulated in inside silencer
Dirt.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind to be useful on blower, the good Novel silencing of sound absorption effect
Device.
The technical solution adopted by the present invention to solve the technical problems is: model muffler, including shell, is arranged on shell
There is sound absorption air port and air outlet, shell are quadrangular frustum pyramid shaped structure surrounded by four sides side wall, both ends open inner hollow, area
Big opening is sound absorption air port, is provided with several blocks of sound-absorbing materials parallel to each other and parallel with air port direction, shell in shell
It is provided with disposal box at upper air outlet, dust filtering cloth bag is provided in disposal box.
The beneficial effects of the present invention are: model muffler of the present invention is provided with several pieces of parallel to each other and and wind in shell
The parallel sound-absorbing material in mouth direction, sound absorption range are wide；It is well known that the sound wave propagated in air is longitudinal wave, continuous shaking
Tuning fork, makes the air molecule of surrounding form the continuous wave of density interphase, and quadrangular frustum pyramid shaped structure can in the horizontal direction effectively
Sound wave is intercepted, working well for noise is absorbed；Disposal box is easy to clean convenient for collecting dust.
Detailed description of the invention
Fig. 1 is cross-sectional view of the invention；
Fig. 2 is perspective view of the invention；
It is denoted as in figure: sound-absorbing material 1, disposal box 2, dust filtering cloth bag 3.
Specific embodiment
The following further describes the present invention with reference to the drawings.
Model muffler, including shell, sound absorption air port is provided on shell and air outlet, shell are surrounded by four sides side wall
, the quadrangular frustum pyramid shaped structure of both ends open inner hollow, the big opening of area is sound absorption air port, be provided in shell several pieces that
This parallel and sound-absorbing material 1 parallel with air port direction is provided with disposal box 2 at air outlet on shell, is provided in disposal box 2
Dust filtering cloth bag 3.
