The simple Novel inflation pump of mode.
The technical solution of the utility model is as follows：
A kind of Novel inflation pump includes cylinder assembly and piston；The cylinder assembly include the protecgulum assembled successively,
Middle cover and rear cylinder, the protecgulum, middle cover and rear cylinder are both provided with connecting hole, connecting hole and nut described in screw bolt passes
Locking makes the protecgulum, middle cover and rear cylinder fix assembling；
The protecgulum and middle cover enclose discharge chamber；The piston be inserted in it is described after cylinder after-opening, the middle cover, after
Cylinder and piston enclose inlet plenum.
Further, it is folded with sealing ring between the protecgulum and middle cover, sealing is folded between the middle cover and rear cylinder
Circle.
Further, the protecgulum is provided with the escape pipe being connected to the discharge chamber；The middle cover be provided with first into
The open front of stomata, first air admission hole is provided with the first catch flexible.
Further, the piston is provided with the second air admission hole, and the open front of second air admission hole is provided with flexible
Second catch.
Further, the piston jacket is equipped with piston ring.
Further, the piston rear end is connected with toggle and motor, and the motor passes through crank connecting link machine
Structure band piston fore-aft travel.
Compared with prior art, the utility model has the advantages that：（1）Protecgulum, middle cover and rear cylinder pass through spiral shell
Screw bolt and nut locks, and is conducive to assembly and disassembly, is convenient for changing or repairs vulnerable part therein；（2）Cylinder assembly is by protecgulum, middle cover
And rear cylinder assembles, amount of parts is smaller and simple in structure, is conducive to production.

Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown in Figs. 1-3, embodiment provided by the utility model, a kind of Novel inflation pump include cylinder assembly and work
Plug 10.Cylinder assembly includes the protecgulum 20 assembled successively, middle cover 30 and rear cylinder 40, protecgulum 20, middle cover 30 and rear cylinder 40
It is both provided with connecting hole, bolt 51 sequentially passes through connecting hole and locked with nut 52, and protecgulum 20, middle cover 30 and rear cylinder 40 is made to fix
Assembling.
Protecgulum 20 and middle cover 30 enclose discharge chamber A；Piston 10 is inserted in the after-opening of rear cylinder 40, middle cover 30, rear cylinder 40
And piston 10 encloses inlet plenum B.It is folded with sealing ring 50 between protecgulum 20 and middle cover 30, is pressed from both sides between middle cover 30 and rear cylinder 40
Equipped with sealing ring 50.Wherein sealing ring 50 can increase leakproofness, avoid protecgulum 20, middle cover 30 and gas leakage between cylinder 40 afterwards.
Protecgulum 20 is provided with the escape pipe 21 being connected to discharge chamber A；Middle cover 30 is provided with the first air admission hole 31, the first air inlet
The open front in hole 31 is provided with the first catch 32 flexible.Piston 10 is provided with the second air admission hole 11, before the second air admission hole 11
Opening is provided with the second catch 12 flexible.
It is arranged with piston ring 13 outside piston 10, piston ring 13 can increase leakproofness, avoid between piston 10 and rear cylinder 40
Gas leakage.
10 rear end of piston is connected with toggle 14 and motor 15, and motor 15 is driven by toggle 14 and lived
Fill in 10 fore-aft travels.
The operation principles of the present embodiment：（1）When piston 10 is movable backward, inlet plenum B generates negative pressure, and the first catch 32 is adjacent to
And the first air admission hole 31 is closed, extraneous gas enters the second air admission hole 11 and blows the second catch 12 open subsequently into inlet plenum B；
（2）When piston 10 travels forward, inlet plenum B generates high pressure, and the second catch 12 is adjacent to and closes the second air admission hole 11, in piston 10
Promotion under, gas in inlet plenum B enters the first air admission hole 31 and blows the first catch 32 open subsequently into discharge chamber A, finally
It is discharged from escape pipe 21.
Above disclosures are merely preferred embodiments of the utility model, with this utility model cannot be limited certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
