Abstract
The invention discloses a kind of silencers, including shell, sound absorption air port and air outlet are provided on shell, shell includes two sections of horizontal sound absorption sections and one section of vertical sound absorption section, the both ends of vertical sound absorption section, which are separately connected two sections of horizontal sound absorption sections, keeps shell S-type, is provided with equally distributed rectangular block shape sound-absorbing material on the vertically inner wall of sound absorption section；Several blocks of sound-absorbing materials parallel to each other and parallel with sound absorption air port direction are provided in horizontal sound absorption section at sound absorption air port, are provided with several blocks of sound-absorbing materials parallel to each other and parallel with direction of air outlet in the horizontal sound absorption section at air outlet.Silencer of the present invention is provided with sound-absorbing material in level sound absorption section and vertical sound absorption section, and sound absorption range is wide；S shell body can effectively intercept sound wave in the horizontal direction simultaneously, absorb working well for noise.
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, and it is poor to absorb sound wave effect.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind to be useful on blower, the good silencer of sound absorption effect.
The technical solution adopted by the present invention to solve the technical problems is: silencer, including shell, is provided with suction on shell
Sound air port and air outlet, shell include two sections of horizontal sound absorption sections and one section of vertical sound absorption section, and the vertical both ends for absorbing sound section connect respectively
Connecing two sections of horizontal sound absorption sections keeps shell S-type, and equally distributed rectangular block shape sound absorption is provided on the vertically inner wall of sound absorption section
Material；Several blocks of sound absorption materials parallel to each other and parallel with sound absorption air port direction are provided in horizontal sound absorption section at sound absorption air port
Expect, is provided with several blocks of sound-absorbing materials parallel to each other and parallel with direction of air outlet in the horizontal sound absorption section at air outlet.
The beneficial effects of the present invention are: silencer of the present invention is provided with horizontal sound absorption section and vertical sound absorption section, vertically inhaling
Be provided with equally distributed rectangular block shape sound-absorbing material on the inner wall of sound section, be provided in level sound absorption section several pieces it is parallel to each other
And the sound-absorbing material parallel with air port direction, sound absorption range are wide；It is well known that the sound wave propagated in air is longitudinal wave, continuously
The tuning fork of vibration, makes the air molecule of surrounding form the continuous wave of density interphase, and S shell body can in the horizontal direction effectively
Sound wave is intercepted, working well for noise is absorbed.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Specific embodiment
The following further describes the present invention with reference to the drawings.
Silencer, including shell, are provided with sound absorption air port and air outlet on shell, shell include two sections of horizontal sound absorption sections and
One section of vertical sound absorption section, the vertical both ends for absorbing sound section, which are separately connected two sections of horizontal sound absorption sections, keeps shell S-type, it is known that
The sound wave propagated in air is longitudinal wave, and the tuning fork of continuous shaking makes the air molecule of surrounding form the continuous wave of density interphase,
S shell body can effectively intercept sound wave in the horizontal direction, absorb working well for noise；It is set on the vertically inner wall of sound absorption section
It is equipped with equally distributed rectangular block shape sound-absorbing material；Be provided in horizontal sound absorption section at sound absorption air port several pieces it is parallel to each other and
With the parallel sound-absorbing material in sound absorption air port direction, be provided in the horizontal sound absorption section at air outlet several pieces it is parallel to each other and with go out
The parallel sound-absorbing material in air port direction, sound absorption range are wide.
