specific Embodiment approach

[0020] Vacuum pump outlet protective cover 3 such as figure 1 , fixed with the vacuum pump 1, the exhaust port 2 of the vacuum pump 1 is in close contact with the exhaust seat 5, and the gas discharged from the exhaust port 2 is buffered in the buffer box 4 and then discharged through a plurality of exhaust holes 6, which is safe and low in noise. The air hole 6 is located at the bottom of the protective cover 3, and the sputtering liquid retained in the gas discharged by the vacuum pump 1 can be discharged from the bottom exhaust hole 6 in droplets after being accumulated in the buffer tank 4; two partitions 8 separate the upper part of the buffer tank into three small chambers, the through hole 7 is located in the middle chamber, and the small chambers on both sides can keep the middle chamber warm, mud-proof, waterproof, frost-proof, and freeze-proof. When sucking, the small chambers on both sides can also prevent most of the airflow from directly rushing into the exhaust p...

Abstract

The invention discloses a protecting hood for an air outlet of a vacuum pump. The protecting hood comprises a vacuum pump. The exhaust port of the vacuum pump faces a base of the vacuum pump, the protecting hood is arranged at the exhaust port of the vacuum pump, the protecting hood comprises a buffer tank and an exhaust seat, the buffer tank is of a box structure, one face of which is opened, theopened face of the buffer tank clings to the outer side face of the vacuum pump, a plurality of exhaust holes are formed in the bottom of the buffer tank, the exhaust seat clinging to the outer sideface of the vacuum pump and the exhaust holes is arranged at the upper end of the buffer tank, and the exhaust seat and the buffer tank are provided with through holes for communication. The protecting hood disclosed by the invention is reasonable in structure and long in service life, prevents a massive air flow from being sucked back to the exhaust holes, and is suitable for an electric vacuum pump.

Description

technical field [0001] The invention relates to the technical field of vacuum pump components, in particular to a protective cover for an air outlet of a vacuum pump. Background technique [0002] As petroleum resources are dwindling and emission regulations are becoming more stringent, energy saving and emission reduction has become a key factor in vehicle design considerations. The traditional mechanical vacuum pump consumes a lot of power, is noisy, and has poor continuous working ability when the engine is running, which can no longer meet the current energy consumption requirements of vehicles. At the same time, the development of pure electric vehicles requires a device that does not depend on engine power and can provide vacuum required for braking in a timely manner. Therefore, electric vacuum pumps have appeared, but the existing electric vacuum pumps have the following problems: the exhaust port of the vacuum pump lacks protection, the exhaust air flow is not well...
