Abstract
The invention discloses a kind of S type silencers, including shell, sound absorption air port and air outlet are provided on shell, shell includes the first sound absorption section, the second sound absorption section, interconnecting piece, first sound absorption section, the second sound absorption section are arc cylindrical shape, interconnecting piece is cylindrical shape, and the both ends of interconnecting piece, which are separately connected the first sound absorption section and the second sound absorption section, keeps shell S-type, is provided with equally distributed circular block shape sound-absorbing material on the inner wall of the housing.The present invention is provided with equally distributed circular block shape sound-absorbing material on the inner wall of the housing, and sound absorption range is wide；S shell body can effectively intercept sound wave in the horizontal direction, absorb working well for noise；The both ends of interconnecting piece are threadedly coupled with the first sound absorption section and the second sound absorption section respectively, the first sound absorption section and the second sound absorption section periodically can be disassembled cleaning dust, easy to repair.
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 S type of sound absorption effect is eliminated the noise
Device.
The technical solution adopted by the present invention to solve the technical problems is: S type silencer, including shell, is arranged on shell
There are sound absorption air port and air outlet, shell includes the first sound absorption section, the second sound absorption section, interconnecting piece, the first sound absorption section, the second sound absorption section
It is arc cylindrical shape, interconnecting piece is cylindrical shape, and the both ends of interconnecting piece, which are separately connected the first sound absorption section and the second sound absorption section, makes shell
Body is S-type, is provided with equally distributed circular block shape sound-absorbing material on the inner wall of the housing.
Wherein, the both ends of interconnecting piece are threadedly coupled with the first sound absorption section and the second sound absorption section respectively.
The beneficial effects of the present invention are: the present invention is provided with equally distributed circular block shape sound absorption material on the inner wall of the housing
Material, sound absorption range are wide；And it is commonly known that the sound wave propagated in air is longitudinal wave, the tuning fork of continuous shaking makes the sky of surrounding
Gas molecule forms the continuous wave of density interphase, and S shell body can effectively intercept sound wave in the horizontal direction, absorb the effect of noise
Fruit is good；The both ends of interconnecting piece respectively with first sound absorption section and second sound absorption section is threadedly coupled, can periodically by first sound absorption section with
Second sound absorption section disassembles cleaning dust, easy to repair.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Section 2, interconnecting piece 3 in the figure, it is marked as the first sound absorption section 1, second absorbs sound
Specific embodiment
The following further describes the present invention with reference to the drawings.
As shown in Figure 1, S type silencer, including shell, it is provided with sound absorption air port and air outlet on shell, shell includes the
One sound absorption section 1, second sound absorption section 2, interconnecting piece 3, the first sound absorption sound absorption of section 1, second section 2 is arc cylindrical shape, and interconnecting piece 3 is
Cylindrical shape, the both ends of interconnecting piece 3, which are separately connected the first sound absorption section 1 and the second sound absorption section 2, keeps shell S-type, in the inner wall of shell
On be provided with equally distributed circular block shape sound-absorbing material.
Preferably, the both ends of interconnecting piece 3 are threadedly coupled with the first sound absorption section 1 and the second sound absorption section 2 respectively.
