Detailed Description
Referring to fig. 1 and 2, the utility model provides a noise reduction structure of an electronic vacuum pump for a vehicle, which comprises a vacuum pump body 1, a vacuum pump aluminum flange 2, an air inlet pipe 3, an air outlet pipe 4 and a noise reduction pipe 5, wherein the vacuum pump aluminum flange 2 is sleeved on the outer surface wall of the vacuum pump body 1, the air inlet pipe 3 is communicated with the vacuum pump aluminum flange 2, the air inlet pipe 3 is provided with an air outlet channel, the air outlet pipe 4 is communicated with the vacuum pump aluminum flange 2, the noise reduction pipe 5 is sleeved on the outer surface wall of the air outlet pipe 4, the noise reduction pipe 5 is in interference fit with the air outlet pipe 4, and the noise reduction pipe 5 is communicated with an air outlet pipe 6.
Further, the noise reduction tube 5 is made of nonmetallic elastic materials.
Further, the noise reduction pipe 5 has a first chamber 7, a second chamber 8 and a third chamber 9, the first chamber 7, the second chamber 8 and the third chamber 9 are sequentially communicated from top to bottom, and the first chamber 7 is communicated with the exhaust duct 6.
Further, the second chamber 8 has a convex structure inside.
In this embodiment, during the operation of the vacuum pump body 1, the air is sucked through the air inlet pipe 3 and is discharged through the air outlet pipe 6 in the air outlet pipe 4, the high-temperature, high-pressure and high-energy air enters the first chamber 7 from the air outlet pipe 6 and enters the second chamber 8, and the high-temperature, high-pressure and high-speed air is relaxed in the second chamber 8 due to the narrow passage of the second chamber 8, and the energy can be further weakened through the corrugation of the second chamber 8, finally the noise and the energy are further diluted through the third chamber 9, and finally the noise is greatly improved, wherein the protrusion structure inside the second chamber 8 can be a wavy protrusion, a conical protrusion or other irregular protrusions, and the noise reducing function can be effectively achieved through the protrusion structure.
The above disclosure is only a preferred embodiment of the present utility model, and it should be understood that the scope of the utility model is not limited thereto, and those skilled in the art will appreciate that all or part of the procedures described above can be performed according to the equivalent changes of the claims, and still fall within the scope of the present utility model.
