In the present invention, upper layer inflator 441 and lower layer's inflator 442 in inflator 44 are spaced apart by inflator partition 41, so that Upper layer inflator 441 and lower layer's inflator 442 are two independent inflators, and gas between the two does not circulate mutually.

When inflator partition 41 moves upwards, the gas in upper layer inflator 441 is compressed, the atmospheric pressure inside and outside inflator 44 Under difference, the gas in upper layer inflator 441 is exported outward by upper layer outlet air flue 26 or upper layer gas storage air flue 28, and check valve makes The gas that must be exported will not flow back into inflator 44；At this point, the upward fortune of gas in lower layer's inflator 442 due to inflator partition 41 It is dynamic, atm difference also is produced inside and outside inflator 44, therefore lower layer's air-breathing air flue 34 delivers gas to lower layer's gas under differential pressure In cylinder 442, and check valve flow back into the gas of output will not in air-breathing cylinder 52.

When inflator partition 42 moves downward, the gas in lower layer's inflator 442 is compressed, the atmospheric pressure inside and outside inflator 44 Under difference, the gas in lower layer's inflator 442 is exported outward by lower layer's outlet air flue 33 or lower layer's gas storage air flue 35, and check valve makes The gas that must be exported will not flow back into inflator 44；At this point, the downward fortune of gas in upper layer inflator 441 due to inflator partition 41 It is dynamic, atm difference also is produced inside and outside inflator 44, therefore upper layer air-breathing air flue 27 delivers gas to upper layer gas under differential pressure In cylinder 441, and check valve flow back into the gas of output will not in air-breathing cylinder 52.

And press pedal 11 that membrane support column 42 is driven to move up and down, so that inflator partition 41 also moves up and down therewith, no matter Inflator partition 41 moves up or down, and the gas output that can be all able to achieve in inflator 44 is achieved in inflator and inflates efficiency Highest.

Inflator of the invention can realize the output of different tolerance according to demand.

In the present invention, when all one's effort is run, the upper layer inflator 441 and lower layer's inflator 442 of 4 inflators 44 are all working, i.e., and 4 Inflator bi-directional synchronization work, at this point, tolerance output is maximum.

Need tolerance output quantity big during actually inflating, when initially inflating, but as tolerance is gradually filled with entire dress When setting, the input of atm number becomes more difficult, needs to reduce tolerance at this time and increases pressure, at this point it is possible to rotate scavenging air valve 6 Ventilation valve deck button 67, changes the tolerance of output, i.e., by the second scavenging air valve 62 gas in gas storage cylinder 53 is no longer inputted Into outlet cylinder 51, thus the upper layer inflator 441 of only 2 inflators 44 and lower layer's inflator 442 are working.

When also continuing needing to reduce tolerance increase pressure, the ventilation valve deck button 67 for rotating scavenging air valve 6 can be continued, changed The tolerance of output makes gas in the upper layer inflator 441 of the left and right sides of outlet cylinder 51 no longer by the first scavenging air valve 61 It is input in outlet cylinder 51, thus lower layer's inflator 442 of only 2 inflators 44 is working.

It elaborates below to entire work step:

Before use, interlocking bar 12 is installed in interlocking bar protrusion 21, the idler wheel 121 of interlocking bar 12 is in the rolling for pressing pedal 11 In slot 111 so that two side pressure pedals 11 can under the induced effect of interlocking bar 12 up-down alternative motion.

At this point, the inflator partition 41 in the inflator 44 of 5 two sides of air cylinder device is respectively at different height, i.e., side inflator every Plate 41 is located at the top in inflator 44, and other side inflator partition 41 is located at the least significant end in inflator 44, therefore presses pedal 11 at this time Height is also different, and inflator partition 41 is located at the side of top, and membrane support column 42 rises with dynamic pressure pedal 11 far from upper cover plate 2, and be at this time the limiting value far from 2 distance of upper cover plate at a distance from upper cover plate 2, and other side inflator partition 41 is located at least significant end Side, membrane support column 42 contacts with dynamic pressure pedal 11 with upper cover plate 2, for minimum of the pressure pedal 11 at a distance from upper cover plate 2 Value.

The pressure pedal 11 far from upper cover plate 2 is pressed, is located at 5 side inflator 44 of air cylinder device with 2 under dynamic pressure pedal 11 Interior inflator partition 41 moves downward, at this point, the upper layer inflator 441 of this 2 inflators 44 starts by 52 air-breathing of air-breathing cylinder, and under Layer inflator 442 then delivers gas to outlet cylinder 51 and gas storage cylinder by lower layer's outlet air flue 33 and lower layer's gas storage air flue 35 In 53, until 441 air-breathing of upper layer inflator of 2 inflators 44 terminates, and 2 gas when pedal 11 will be pressed to be pressed into contact upper cover plate 2 Lower layer's inflator 442 of cylinder 44 will be in the gas in lower layer's inflator 442 all output to outlet cylinder 51 and gas storage cylinder 53.

Under the effect of interlocking bar 12, during the primary pressure pedal 11 of pressing, the pressure pedal 11 of the other side can rise therewith It rises.For another side pressure pedal 11 during transporting rise, 2 under the pressure pedal 11 of the other side are located at 5 side gas of air cylinder device Inflator partition 41 in cylinder 44 is dynamic upwards.At this point, lower layer's inflator 442 of this 2 inflators 44 starts by 52 air-breathing of air-breathing cylinder, and Upper layer inflator 441 then delivers gas to outlet cylinder 51 and gas storage gas by upper layer outlet air flue 26 and upper layer gas storage air flue 28 In cylinder 53, until 442 air-breathing of lower layer's inflator of 2 inflators 44 terminates, and 2 inflators when will press pedal 11 separate to limiting value 44 upper layer inflator 441 will be in the gas in upper layer inflator 441 all output to outlet cylinder 51 and gas storage cylinder 53.

Gas in gas storage cylinder 53 connects the output of air flue 29 to outlet cylinder 51, under above-mentioned movement, storage by upper layer Gas in gas cylinder 53 connects air flue 29 by upper layer always and exports to outlet cylinder 51, and prevents gas from returning by check valve Stream.

Pressing pressure 11,4 inflators 44 of pedal repeat above-mentioned movement again, and two side pressure pedals 11 successively move up and down always, And several check valves prevent gas backstreaming, so that movement in inflator 44 also repeated work.

Therefore when successively pressing two side pressure pedals 11, in 4 inflators, there are under 2 upper layer inflators 441 and 2 always The layer outside outlet of inflator 442, in addition 2 upper layer inflators 441 and 2 442 air-breathings of lower layer's inflator, that is, be always the two-way work of four inflators Make.

When needing to reduce tolerance increase pressure, rotation ventilation valve deck button 67, drives the second scavenging air valve 62 to rotate, makes counterclockwise The ventilation air flue obtained in the second scavenging air valve 62 changes, and becomes through-hole on the second scavenging air valve from the second scavenging air valve lower through-hole 622 621, under the barrier action of second partition 623, upper layer connects the gas in air flue 29 will by through-hole 621 on the second scavenging air valve For gas to the unencapsulated output suitable for reading of the second scavenging air valve 62, the second scavenging air valve 62 is unencapsulated suitable for reading outer can directly to lead to external The scavenging air valve lid venthole 662 of gas, so that not entering back into outlet cylinder 51 into the gas in gas storage cylinder 53, that is, is stored up The gas of upper layer inflator 441 and lower layer's inflator 442 output of 2 inflators 44 of 53 two sides of gas cylinder does not enter back into outlet cylinder 51 It is interior, at this point, into the gas in outlet cylinder 51 be only 2 inflators 44 of 51 two sides of outlet cylinder upper layer inflator 441 and under Layer inflator 442, as double inflator two-way operations.

When needing to continue to reduce tolerance increase pressure, continue rotation ventilation valve deck button 67 counterclockwise, at this time the second scavenging air valve 62 keep, the rotation of the first scavenging air valve 61, so that the ventilation air flue in the first scavenging air valve 61 changes, by leading under the first scavenging air valve Hole 612 becomes through-hole 611 on the first scavenging air valve, the gas under the barrier action of first partition 613, in upper layer outlet air flue 26 By through-hole 611 on the first scavenging air valve by gas the unencapsulated output suitable for reading of the through-hole 611 on the first scavenging air valve, the first scavenging air valve 61 it is unencapsulated it is suitable for reading it is outer for can with the external scavenging air valve lid venthole 662 directly ventilated so that 51 two sides 2 of outlet cylinder Gas in the upper layer inflator of a inflator 44 does not enter back into outlet cylinder 51, at this point, only into the gas in outlet cylinder 51 For lower layer's inflator 442 of 2 inflators 44 of 51 two sides of outlet cylinder, as double inflator one-way only operations.

A specific embodiment of the invention is discussed in detail above, to those of ordinary skill in the art, Without departing from the principle of the present invention, can be with several improvements and modifications are made to the present invention, these improvement and modification It belongs to the protection scope of the claims of the invention.
