Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, a novel silencer comprises an inner tube 1, wherein N ribs 11 are uniformly arranged on the inner wall of the inner tube 1, N is greater than or equal to 3, the ribs 11 extend spirally from one end to the other end along the inner wall of the inner tube 1, the spiral direction of the ribs 11 and the diameter of the inner tube 1 form an angle of 15-70 degrees, the specific angle 111 formed by the ribs 11 and the inner wall of the inner tube 1 is shown in fig. 2, the distance between the ribs 11 is 20-50cm, the ribs 11 are square, triangular or circular, and the height of the ribs 11 is 0.01-0.05 times of the diameter of the inner tube 1;

the outer wall of the inner tube 1 is wrapped by an elastic buffer layer 2, the elastic buffer layer 2 is specifically made of elastic rubber, an outer tube 3 is sleeved outside the elastic buffer layer 2, a plurality of reinforcing ribs 21 are uniformly distributed between the outer tube 3 and the elastic buffer layer 2 to enhance the strength of the silencing tube, a foaming material is filled between the inner wall of the outer tube 3 and the outer wall of the elastic buffer layer 2 to reduce noise, and the foaming material can be specifically one of a polyethylene foaming material, a polyurethane foaming material and a polystyrene foaming material;
