The automobile exhaust silencer without water accumulation and low noise enters air through the air inlet pipe 11, the air flow is buffered and shunted through collision between the buffer cover 4 and the air flow, and simultaneously the next part of water vapor is blocked and drops from the buffer cover 4 after being condensed into liquid drops, the liquid drops flow into the water chute 2 from the water leakage port 10 due to the inclination action of the bottom of the silencing box 1, other liquid drops condensed inside the silencing box 1 all flow into the water chute 2 due to the inclination drop of the bottom of the silencing box 1 and flow into the drain pipe 12 along the water chute 2 to be discharged without punching and draining, so that the automobile exhaust silencer is more reliable, waste gas is blocked and shunted by the buffer cover 4 and passes through the gas guide pipe 5, in the process, the waste gas presses the U-shaped plate 8 to drive the dredging rod 9 to move, the dredging rod 9 is inserted into the water chute 2 and the drain pipe 12 to dredge the drain passage and avoid blockage, and simultaneously, the waste gas is discharged from the exhaust pipe 14 after being silenced by the silencing component, and the water discharge pipe 12 are crossed to the delivery pipe 13, because the flow velocity of the air current, the air pressure in the delivery pipe 13 is reduced, the water drops in the water chute 2 and the water discharge pipe 12 are pressed into the delivery pipe 13, so as to facilitate water discharge, in addition, the invention is different from the silencing of a plurality of staggered pipelines in the prior art, but the invention divides the wind power through the buffer cover 4, buffers the wind power impact through the first silencing plate 15 and the second silencing plate 16 which are staggered, silences the passing waste gas through the hole 17, has limited resistance to the waste gas, is mainly used for buffering weakening, does not cause the high exhaust back pressure and the loss of the engine power, correspondingly, the invention utilizes the silencing cotton 23 to assist the sound insulation from the side wall through the effect of the sound insulation mechanism, further improves the sound insulation effect without influencing the exhaust back pressure, or utilizes the three groups of sound insulation baffles 25 to insulate sound, and forms the sound insulation interval between the adjacent sound insulation baffles 25 through the connection of the sticky pads 27, the noise is guided and blocked by the sound-absorbing holes 26 which are staggered from each other, and the sound-insulating effect is further improved without affecting the exhaust back pressure.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
