Embodiment
Referring to figs. 1 through Fig. 2, a kind of silencing apparatus embodiment for the exhaust of small displacement compact type of the utility model is described further.
Present embodiment discloses a kind of silencing apparatus for the exhaust of small displacement compact type, comprise front baffler 1, the inner space of front baffler 1 by the first dividing plate 14 and second partition 15 in turn be separated into the first cavity, the second cavity and the 3rd cavity.
The chamber, one end first 11 of the present embodiment supplying tube 17 extend out to the outside of front baffler 1 as inlet hole, and the other end stretches in the 3rd cavity through after the second cavity; Meanwhile, the tube wall being positioned at the second chamber portion at supplying tube 17 offers delivery outlet group 181; In addition, one end of output tube 18 stretches in the first chamber 11, and the other end, through behind the second chamber, extend out to the outside of front baffler 1 as air outlet hole through the 3rd chamber 13; Meanwhile, the first dividing plate 14 offers perforation.
Said structure according to the present embodiment designs, and the 3rd chamber 13 and supplying tube 17 part stretching to the 3rd chamber 13 constitute the resonance noise-reducing structure of collateral branch's pipe, can low frequency noise effectively in eliminating waste gas; The perforation of the second chamber, input hole group and the first dividing plate 14 constitutes in fact the first expansion noise-reducing structure, in order to the intermediate frequency noise in eliminating waste gas; The perforation of the first dividing plate 14, the first chamber 11 and output tube 18 constitute the second expansion noise-reducing structure, the intermediate frequency noise further in eliminating waste gas.The structural design of the present embodiment is very simple, compact, and has the function of good filtering medium and low frequency noise.
In addition, second chamber of the present embodiment is further advanced by the intermediate clapboard 16 with perforation and is separated into left chamber 121 and right chamber 122; Wherein, the first dividing plate 14 separates left chamber 121 and the first chamber 11, and second partition 15 separates right chamber 122 and supplying tube 17 successively through stretching in the 4th chamber behind the first chamber 11, left chamber 121 and right chamber 122; Moreover, the tube wall that supplying tube 17 is positioned at left chamber 121 part offers left input hole group 171, its tube wall being positioned at right chamber 122 part offers right input hole group 172.So, by said structure, the perforation of the present embodiment left input hole group 171, left chamber 121 and the first dividing plate 14 forms left chamber 121 and expands noise-reducing structure; The perforation of right input hole group 172, intermediate clapboard 16 and right chamber 122 form right chamber 122 and expand noise-reducing structure, and therefore left chamber 121 is expanded noise-reducing structure and right chamber 122 and expanded intermediate frequency noise in the removal waste gas that noise-reducing structure can be arranged side by side.
In addition, the aperture of left input hole group 171 is not identical with the aperture of right input hole group 172, can be used for eliminating the intermediate frequency noise of different frequency range.
Moreover the present embodiment removes the high frequency noise in waste gas further by the after silencer with resistive noise-reducing structure.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
