Abstract

The utility model relates to an air compressor with low noise, which comprises a motor, a stator, a rotor, a base seat and a shell. The utility model is characterized in that the cross section of an air suction opening on the base seat forms a streamline shape, and a high-pressure chamber in the shell is connected with a magnetic filter for filtering lubricant oil.

Description

Air compressor

Technical field

The utility model relates to a kind of compressor, particularly a kind of low noise air compressor.

Background technique

Among the disclosed Chinese patent bulletin CN2398448Y a kind of " blade type air compressor " disclosed on September 27th, 2000, it comprises head, radiator, thermocouple, motor, gas holder and pneumatic tube, wherein the driven by motor rotor rotates in the stator of off-centre, blade is close to the inwall wall rotation of stator and is produced pressurized air under action of centrifugal force, and has adopted constant temperature, stable-pressure device; The intakeport cross section of existing this air compressor is square, and its shortcoming is that noise is big.

Summary of the invention

The purpose of this utility model is the big problem of noise that exists in the existing air compressor in order to solve, and provides a kind of noise little air compressor.

Technological scheme:

The purpose of this utility model is achieved in that a kind of air compressor, comprises motor, stator, rotor, pedestal and housing, it is characterized in that the intakeport cross section on the pedestal is a streamline.

Described air compressor is characterized in that the hyperbaric chamber in the housing is connected to magnetic filter.This magnetic filter is used for filtering lubricant oil.

Described air compressor, the outer end cap that it is characterized in that described pedestal outer end is provided with zone of high pressure and low pressure area, wherein low pressure area communicates with atmosphere, the zone of high pressure communicates with gas holder, passage between zone of high pressure and the low pressure area is provided with safety valve, this safety valve is made of valve port, sealing block, spring and adjusting nut, and described spring is arranged between sealing block and the adjusting nut.

Beneficial effect:

Owing to adopted technological scheme described in the utility model, the intakeport cross section of compressor is set to the arc of streamline, has reduced the noise of air stream when intakeport; The magnetic filter that joins with the zone of high pressure can be with the absorption of the irony in the lubricant oil of flowing through, and has reduced the wearing and tearing of stator, rotor, prolongs the life-span of compressor; Safety valve structure on the outer end cap is simple, be easy to regulate.
