Abstract
The invention relates to the technical field of silencers, and particularly provides a silencer which is better in noise elimination effect. The silencer comprises a silencer main body, an air inlet pipe, an exhaust pipe and a strip outer cover, wherein the silencer main body is accommodated in at least part of the strip outer cover; the strip outer cover and the silencer main body are fixed through screws; the air inlet direction of the air inlet pipe is perpendicular to the exhaust direction of the exhaust pipe; an exhaust port is formed on the strip outer cover; and the exhaust pipe is connected with the exhaust port after being bent. In the silencer, by arranging a shell, a certain silencing and heat insulation effect can be enhanced, and the silencer is more attractive in appearance; the air inlet direction of the air inlet pipe is perpendicular to the exhaust direction of the exhaust pipe, so more collision can be produced during flowing of airflow, and the disorder degree of the airflow is increased to achieve a better silencing effect; and the exhaust pipe is bent, so nearly axial waves in sound waves can be absorbed and reflected at a bending position, and the energy of the nearly axial waves can be transformed into the energy of oblique waves during bending to be easily absorbed.

Summary of the invention
In view of this, the purpose of this invention is to provide a kind of better strip silencer of noise effects of eliminating.
The object of the present invention is achieved like this: strip silencer, comprise muffler body, suction tude and outlet pipe, described silencing apparatus also comprises the bar shaped outer cover, the at least part of muffler body of holding of described bar shaped outer cover, described bar shaped outer cover and muffler body are fixed by screw, the airintake direction of described suction tude is vertical with the discharge directions of outlet pipe, is provided with relief opening on the described bar shaped outer cover, is connected with relief opening after the outlet pipe bending.
Further, described muffler body inside is divided into chamber I, chamber II and chamber III successively by dividing plate, the exhaust end of described suction tude stretches in the chamber I and with chamber I and is communicated with, chamber I is communicated with by pipe I with chamber III, chamber III is communicated with by pipe II with chamber II, and the inlet end of described outlet pipe is communicated with chamber II.
Further, described muffler body comprises inner casing and shell, is placed in the shell in the described inner casing.
Further, described inner casing and shell are spliced by two and half shells respectively.
Further, be provided with the sound-absorption and heat-insulation layer between described inner casing and the shell.
Further, the sealing of described pipe I both ends of the surface is provided with a plurality of holes that are communicated with chamber III with chamber I respectively on the sidewall at pipe I two ends.
Further, the sealing of described pipe II both ends of the surface is provided with a plurality of holes that are communicated with chamber III with chamber II respectively on the sidewall at pipe II two ends.
Further, the sealing of the inlet end end face of described outlet pipe, outlet pipe is communicated with chamber II by the hole that is arranged on its sidewall.
Further, the inlet end of described outlet pipe passes chamber III and stretches into chamber II.
Further, be provided with relief opening on the described shell, outlet pipe is connected with relief opening.
The invention has the beneficial effects as follows: be provided with shell, can increase certain noise reduction and effect of heat insulation, make simultaneously outward appearance more attractive in appearance, the airintake direction of described suction tude is vertical with the discharge directions of outlet pipe, can make air-flow in flow process, produce more collision, increase the disorderly degree of air-flow, better soundproof effect, the outlet pipe bending, nearly axial wave in the sound wave can be absorbed and reflect in the elbow, and the energy of nearly axial wave also can change the energy of oblique wave into and easily be absorbed when turning round.Further in the technological scheme, 3 buffer chamber are set, air-flow is fully cushioned, and by the setting to 3 buffer chamber overcurrent orders, air-flow is repeatedly bumped with chamber wall, increase soundproof effect; In further technological scheme, also be provided with the sound-absorption and heat-insulation layer between inner core and the urceolus, further increase soundproof effect, and have effect of heat insulation; Outlet pipe, pipe I and/or pipe II all are communicated with chamber by a plurality of apertures, when air-flow passes through through hole, the frequency spectrum of jet noise will shift to high frequency or ultra-high frequency, the audible sound composition in the frequency spectrum is obviously reduced, thereby minimizing is to people's interference and injury.
