Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is expanded on further.Only should be understood that these embodiments For this utility model being described rather than limiting scope of the present utility model.In addition, it is to be understood that reading After the content that this utility model is lectured, this utility model can be made various changing by those skilled in the art Moving or amendment, these equivalent form of values fall within the application appended claims limited range equally.

As shown in figs. 1-7, embodiment of the present utility model relates to a kind of overall plastic aerating device of multi-cylinder, bag Including motor 4 and housing 3, the inner hollow of described housing 3 and inner horizontal are that reversed arrangement has a pair work Stopper rod 7, the two ends of described housing 3 have been arranged symmetrically with end plates 2, and the outside of these end plates 2 is all close to Being provided with air inlet and outlet end plate 1, one end of described piston rod 7 is disposed with swing hole 12, two piston rods 7 Swing hole 12 arranged superposed, the middle part of described housing 3 is vertically-mounted motor 4, this motor 4 Rotate in bar 11 extends down into swing hole 12 and be connected with eccentric 10, the sidewall of this eccentric 10 and Two inwalls swinging hole 12 are in contact, and the other end of described piston rod 7 is disposed with sealing cup 9, Sealing cup 9 is clamped together with piston rod 7 by the outboard end of this sealing cup 9 by leather cup pressing plate 8；

Forming inlet chamber 16 and outlet chamber 17 between described end plates 2 and air inlet and outlet end plate 1, this goes out Air cavity 17 is connected with the outlet nozzle of air inlet and outlet end plate 1 upper end, the described end plates 2 in outlet chamber 17 On have venthole 18, the described end plates 2 in inlet chamber 16 have air inlet 14, described End plates 2 are provided with, on the side of leather cup pressing plate 8, the rubber inlet valve 19 covered by air inlet 14, The opposite side of described end plates 2 is provided with the rubber air outlet valve 13 covered by venthole 18.

This device twin-tub is supported or opposed design, can be substantially reduced shaking force during inflation, when left side cylinder exhaust, Another the right cylinder enters suction condition；Eccentric is played balanced action, thus reaches stable purpose.

The twin-tub of this device is supported or opposed to design and is used same eccentric 10, during the cylinder exhaust of the left side, and electricity When stream increases, the right cylinder is just in breathing process just, loads the least.When the right cylinder piston apical grafting During near-end panel 2, owing to acting on same eccentric 10, by means of the inertia of left side cylinder piston, rapidly On the right of help, cylinder completes aerofluxus task, power consumption during high cylinder pressure on the right of reduction, makes electric current during high pressure Decline to a great extent, stop to burn when inflation the phenomenon of automobile fuse.

Supplement as to the one of technical scheme described in the utility model, described rubber inlet valve 19 He Rubber air outlet valve 13 is rubber sheet, and rubber sheet is middle fixing, and surrounding is floated, as air inlet or row During gas, it is not necessary to whole valve is opened, only open at outer shroud one circle, reduce the area that valve is opened, Reduce the power consumption opening valve；Because when high pressure, the pressure outside valve is the biggest, area and pressure Being directly proportional, the periphery of this bulla slightly upwarps, and gas is with regard to smooth and easy discharge.So, when high pressure, power Current boost is few, reaches the effect of hyperbar low current.

Supplement as to the one of technical scheme described in the utility model, described venthole 18 and air inlet Hole 14 is arranged circumferentially about composition by several apertures, and port uses the design broken the whole up into parts, and has many Individual annular array small sircle hole combines, it is ensured that enough go out throughput, makes aerofluxus smooth, around steam vent Temperature is substantially reduced, and has both reduced the high temperature that compression produces, has made again electric current slow down lifting.

Further, described venthole 18 and air inlet 14 and rubber air outlet valve 13 and rubber air inlet Be disposed with one layer of round platform protruded on the end faces that are affixed of door 19, this round platform plane and rubber air outlet valve 13 or Rubber inlet valve 19 fits, and has facet to fit with valve film, improves its air-tightness, due to plane Long-pending the least, when valve closure, reduce contact surface, effectively reduce strike note during valve closure.

Further, the bottom of described sealing cup 9 is rounded transition, but leather cup pressing plate 8 is straight Angle；When pressing plate compresses leather cup, the tension launched to the collar extension extroversion of leather cup, open when having aerofluxus, inhale The effect zoomed in during gas, makes the collar extension of leather cup be adjacent to cylinder inner wall, improves air-tightness, reduces electric current.

Further, between side and the housing 3 of described end plates 2, O-ring seal 20 is installed, Improve sealing effectiveness.

Further, between described end plates 2 and air inlet and outlet end plate 1, it is disposed with shaped as frame sealing strip 15, Inlet chamber 16 and outlet chamber 17 separation are surrounded two independent spaces by this shaped as frame sealing strip 15, utilize frame Shape sealing strip 15 separates inlet chamber 16 and outlet chamber 17 can effectively prevent the situation of gas leakage.

Further, instrument has all been mounted side by side on described air inlet and outlet end plate 1 and has connected interface 6 He of giving vent to anger Inflatable interface 5, instrument connects interface 6 of giving vent to anger and may be used for installing the instrument such as air gauge, convenient observation both sides The pressure given vent to anger.

Further, the inflatable interface 5 on two air inlet and outlet end plates 1 is by trachea and three-way connector phase Even, threeway can giving vent to anger both sides all to import and allow gas to together go out simultaneously, it is ensured that gives vent to anger is steady Qualitative.

Further, the position that described air inlet and outlet end plate 1 communicates with inlet chamber 16 has external feed stream Hole 22, facilitates air inlet.

This utility model simple in construction, uses twin-tub design of supporting or opposing to instead of original single cylinder or the most double Cylinder structure, and use eccentric to drive two cylinders to move back and forth, it is substantially reduced shaking force during inflation, This is the technological revolution in an inflator pump field, to cater to huge vehicle-mounted inflator pump market, it is achieved allow generation Made in China target is known on boundary.
