Description
Technical field
The present invention relates to vacuum pump technology field, in particular to a kind of Vehicular electric diaphragm vavuum pump.
Background technology
Current Vehicular electric vavuum pump mainly has piston type vacuum pump, rotary-vane vaccum pump and diaphragm vavuum pump.Although film
Chip vavuum pump, far better than piston type and rotary-vane vaccum pump, but is due to that traditional diaphragm is true in reliability and Energy Efficiency Ratio
Empty pump volume is more huge, and limited frequently result in space can not install and use on car.
For example application publication number be CN 105889041 A, CN 105952624 A, CN 105889042 A middle promulgated by the State Council
Bright patent, disclosing diaphragm type electric vacuum pump for automobile and parts includes offering intake and exhaust on motor and the pump housing, the pump housing
Left and right end-cap assembly is provided with road, the left and right ends of the pump housing, left and right end-cap assembly is internally provided with suction muffler and discharge chamber, entered
Exhaust duct is respectively communicated with the suction muffler of left and right end-cap assembly, discharge chamber, and outlet port cap assemblies include end cap and shield, end cap with
Shield formation first-level buffer chamber and level 2 buffering chamber, end cap check valve is provided with first-level buffer intracavitary, and level 2 buffering intracavitary has suction
Sound sponge, gas is discharged by steam vent again by the entering and exhaust channel of the pump housing.This several prior art disclosures have pumping
More preferably, noise is smaller, and safety coefficient is higher, and service life is longer, and cumulative operation time can reach more than 1200 hours for performance.On
State several prior arts and although solve that traditional diaphragm vavuum pump volume is more huge, limited frequently result in space can not on car
The problem of installing and using, but left and right end-cap assembly and lateral plate structure are complex, and processing, assembling are all complex；In addition, side plate
Lack seal between end cap, sealing effectiveness is bad, and pumping efficiency is low.
The content of the invention
In order to solve the above-mentioned technological deficiency of prior art presence, it is an object of the invention to provide a kind of Vehicular electric film
Piece vavuum pump, solve in the prior art it is complicated, the problem of pumping efficiency is low.
In order to realize above-mentioned purpose of design, the scheme that the present invention is used is as follows：
