Embodiment
It is that the following description is substantially merely exemplary and be not intended to limit the disclosure, application or purposes.Below
The embodiment of the utility model Vehicular electric diaphragm vavuum pump is further described with reference to Figure of description.
As Figure 1-Figure 4, according to the structural representation of Vehicular electric diaphragm vavuum pump of the present utility model.It is a kind of automobile-used
Electronic diaphragm vavuum pump, including motor 1, crankcase 2, bonnet 3, valve plate 4, connecting rod 6, silencer 9 and suction joint 11, motor 1
Direct connection drives eccentric shaft 10；The 6 symmetrical distribution of bonnet 3, valve plate 4 and connecting rod, the end of connecting rod 6 are provided with diaphragm 7, the bonnet
Sealed between 3 and valve plate 4 provided with special-shaped seal ring 5, pumping efficiency is high.
Vehicular electric diaphragm vavuum pump of the present utility model, which has, to operate steadily, and pumping efficiency is high, compact-sized, volume
It is small, in light weight, the advantages that being easily installed arrangement.
Vehicular electric diaphragm vavuum pump of the present utility model uses horizontally-opposed structure, the direct connection of motor 1 driving eccentric shaft 10
Rotation, by the transmission of connecting rod 6, diaphragm 7, connecting rod 6 just move reciprocatingly, the work being made up of valve plate 3 and connecting rod 6, diaphragm 7
Volume then can generating period change.When diaphragm 7, connecting rod 6 are from outer dead point to lower dead center setting in motion, swept volume gradually increases
Greatly, now gas i.e. along suction joint 11, is pushed the air-intake valve plate on special-shaped seal ring 5 open and entered in working chamber, Zhi Daogong
Untill when changing to maximum as volume, air-intake valve plate closing air inlet.When connecting rod 6 when diaphragm vavuum pump, 7 counter motion of diaphragm,
Swept volume is reduced, gas pressure rise, and the exhaust valve plate on special-shaped seal ring 5 is pushed open by work intracavity gas, and gas is through pipe
Road is discharged into crankcase 2, and until piston movement is untill extreme position, exhaust outlet is closed.
Said process repeats.In a word, the eccentric shaft 10 of diaphragm vavuum pump rotates a circle, diaphragm 7, connecting rod 6 reciprocal one
It is secondary, air-breathing, compression, the process of exhaust are realized in working chamber in succession, that is, completes a working cycles.
The course of work of Vehicular electric diaphragm vavuum pump of the present utility model is：Motor 1, motor are laid on crankcase 2
Main shaft direct connection driving eccentric shaft 10 is rotated, and deep groove ball bearing 8 is disposed with eccentric shaft 10, and bearing outer ring lays connecting rod 6, connecting rod 6
Small head end be connected through a screw thread diaphragm 7, and form swept volume with valve plate 4；The outside of valve plate 4 lay be integrated with into, arrange
The special-shaped seal ring 5 of air valve plate effect, and form intake and exhaust channel with bonnet 3.In addition suction joint is there also is provided on crankcase
11 and exhaust silencer 9.Gas is sucked by suction joint 11 during work, flows to bonnet 3, the valve plate 4 of the both sides of crankcase 2 respectively,
And discharged by air inlet and exhaust valve from the inside of crankcase 2, most discharge air through silencer 9 afterwards.
Referring next to shown in Fig. 5, in the embodiment illustrated in fig. 4 according to Vehicular electric diaphragm vavuum pump of the present utility model
The structural representation of special-shaped seal ring.
In the present embodiment, the special-shaped seal ring 5 uses integrated design, is integrated with exhaust valve plate 83, air-intake valve plate
84th, outer course sealing ring 82 and Nei Dao O-rings 81.
In the present embodiment, the exhaust valve plate 83 is set with the centering of air-intake valve plate 84.
In the present embodiment, the centre of the exhaust valve plate 83 and air-intake valve plate 84 is provided with manhole.
In the present embodiment, one end of the outer course sealing ring 82 is semi arch hatch frame 80；Outer course sealing ring 82
The other end is rectangular closed structure 85.
Special-shaped seal ring 5 is U-loop for one end of a circular seal ring, and the other end is with the sealing ring for closing U-loop.
It will be apparent to those skilled in the art that the special-shaped seal ring of the present utility model for Vehicular electric diaphragm vavuum pump
