Structure, with regard to noise elimination can be played the role of；Partition board is static setting, and the air-flow of first chamber itself can generate circulation, air-flow
It can play the role of noise elimination when flowing through the airflow hole of partition board；It is realized by fluid dividing cover and carries out further sound deadening, same to time-division
Stream cover makes air also effectively hinder the strike note of cylinder interior gas valve plate even into cylinder；Using the above structure
Muffler, structure is simpler, and structural strength is reliable, and quality can be lighter, and pass through multiple sound deadening, disappear
Audio fruit improves 50% than the silencer in existing design.
Description of the drawings
Fig. 1 is a kind of structure diagram of muffler embodiment of the utility model.
Fig. 2 is a kind of schematic cross-sectional view of muffler embodiment of the utility model.
Fig. 3 is the structure diagram of silencing means in a kind of muffler embodiment of the utility model.
Specific embodiment
It is described further referring to figs. 1 to a kind of muffler embodiment of 3 pairs of the utility model.
A kind of muffler, including outer cover 1 and the fixed seat 2 being placed on 1 one end of outer cover, outer cover 1 is equipped with air inlet pipe 3, Gu
Reservation 2 is equipped with air outlet pipe 4, and silencing means 5 is equipped in the outer cover 1, and silencing means 5 includes outer cover 1 being separated into the first chamber
The partition board 8 of room 6 and second chamber 7, the fluid dividing cover 9 for being placed in 4 inlet end of air outlet pipe, first chamber 6 connected with air inlet pipe 3 and into
The airintake direction of tracheae 3 and the internal perisporium of first chamber 6 are tangentially-arranged, and second chamber 7 is connected with air outlet pipe 4, and partition board 8 is equipped with
The airflow hole 10 of first chamber 6 and second chamber 7 is connected, the side wall of fluid dividing cover 9 is equipped with several tap holes 11.
By tangential admission, air can naturally generate circulation, the dynamic property noise of consumed cabin air in first chamber 6；
When and pass through partition board 8 to air carry out choked flow, make partial air pass through airflow hole 10 uniformly flow into second chamber 7 play, noise reduction
Effect, the generation of another air turns back, continues circulation in first chamber 6, further function as the effect of noise reduction；When air edge
When in the axial inflow second chamber 7 of airflow hole 10, it can generate repeatedly to turn back between 2 inner wall of partition board 8 and fixed seat and play into one
Walk the effect of noise reduction；When air in second chamber 7 encounters fluid dividing cover 9, partial air flows to air outlet pipe 4 by tap hole 11,
Another part air is obstructed to generate in second chamber 7 again and turn back, and further functions as the effect of noise reduction.
