Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of noise-reducing structure is described including hush pipe 1 and the noise reduction core 2 being arranged in hush pipe 1
Several bloops are provided on noise reduction core 2, the inlet end of the noise reduction core 2 is connected with vacuum generator 3, absorbs make an uproar at the first time
Sound, excellent noise reduction effect.Noise reduction component is provided between the hush pipe 1 and noise reduction core 2.Furthermore, the noise reduction group
Part includes the sponge being sleeved on the noise reduction core 2.The hush pipe 1 has inlet chamber and what is be connected with the inlet chamber goes out
Air cavity, the noise reduction core 2 have the first noise elimination part 4 being located in the inlet chamber and the second noise reduction in the outlet chamber
Portion 5.The bloop includes the first bloop 6 being arranged in first noise elimination part 4 and is arranged in second noise elimination part 5
On the second bloop 7, the sponge includes being sleeved in first noise elimination part 4 to wrap up the first of first bloop 6
Sponge 8 and it is sleeved on the second sponge 9 that second bloop 7 is wrapped up in second noise elimination part 5, sponge can effectively absorb
Noise reduces air resonance.There is isolation part 12, first noise elimination part 4 and the second noise elimination part 5 difference on the noise reduction core 2
Positioned at the two sides of the isolation part 12, the diameter of the inlet chamber is greater than the diameter of the outlet chamber, after assembly, the isolation part
12 side is against the inside of the inlet chamber, and inlet chamber and outlet chamber are isolated, and realizes secondary noise reduction, improves noise reduction effect.
