Abstract
The utility model relates to an automotive purifying silencer which belongs to an automobile part. A tail gas inlet 1 is connected with an outer cavity 3 of the silencer through four tail gas exhaust holes 2. Four air inlets 4 arranged between the tail gas inlet and the silencer are connected with an inner cavity 5 of the silencer. Each air inlet and each tail gas exhaust hole are arranged in intervals. The inner wall of the outer cavity and the outer wall of the inner cavity are provided with friction sheets 6. A filter net 7 is arranged on the tail part of the outer cavity of the silencer. The utility model with novel structure has the advantages that the automotive purifying silencer not only has the function of silencing, but also has the function of purifying automobile tail gas; the utility model capable of reducing pollution has a good environment protecting effect.
Description
The utility model belongs to automobile component.
The used baffler of automobile generally only plays sound deadening at present, the effect that tail gas pollution is reduced, and its shortcoming is a function singleness, incompatible present more and more higher environmental requirement.
The purpose of this utility model is to provide a kind of novel mobile muffler, makes it to play on the noise reduction basis effect that reduces tail gas pollution.
For achieving the above object, the technological scheme that the utility model is taked is: gas inlet 1 is connected with the exocoel 3 of this baffler by 4 to 6 last person's pores 2,4 to 6 air inlets 4 are arranged between gas inlet place and baffler, this air inlet all is connected with the inner chamber 5 of baffler, and each air inlet and each last person's pore are provided with at interval, the inner chamber of this baffler does not communicate with exocoel, on the outer wall of cavity wall and inner chamber friction plate 6 is arranged outside, on this friction plate, be drilled with the hole of 3～4 millimeters of diameters, filter screen 7 be housed at the afterbody of baffler exocoel.During use, tail gas enters in the baffler exocoel by last person's pore behind gas inlet, under the effect of friction plate and filter screen, reach the purpose of noise reduction, owing to by a large amount of air, baffler is played cooling effect in the inner chamber, pollutants a large amount of in the tail gas can be trapped on the friction plate.
The utility model advantage is a novel structure, makes the baffler of automobile not only have sound deadening, has the effect of purifying automobile tail gas simultaneously, can reduce pollution, and environment protection effect is preferably arranged.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
