One end far from the second valve block 7, the outside through valve box 1 pass inwardly through the second axis hole, and with the second shaft hole matching, and can be free
It slides axially.The side wall of the one end of the second valve shaft 15 far from the second valve block 7, which is equipped with, prevents the second valve shaft 15 from deviating from the second axis
The circumferential projection in hole.Second valve block 7 and the second air flue 3 are located at one end gluing, sealing outside valve box 1.By first of annular
The first supporter 8 that support seat 16 and the more first support bars 17 for being vertically set on 16 side of the first support base are constituted.First
Seat 16 is supportted between the first valve block 6 and the first sieve plate 10, the first sieve plate 10 corresponds to each first support bar 17 and offers perforation
Hole, the one end of each first support bar 17 far from the first support base 16 are located at the side of valve box 1 along respective through the first sieve plate 10
Corresponding through hole is pierced by the first sieve plate 10, and is connected with deflation button 18.Include being hung down by the second support base 19 of annular and more
Straight the second supporter 9 being arranged in the composition of second support bar 20 of 19 side of the second support base.Second support base 19 is located at second
Between valve block 7 and the second sieve plate 13, the second sieve plate 13 corresponds to each second support bar 20 and offers through hole, each second support
The one end of bar 20 far from the second support base 19 is worn through the second side of the sieve plate 13 far from valve box 1 along corresponding through hole
Enter in valve box 1, and is contacted with the first valve block 6.It is located at the external screw thread 21 outside valve box 1 in the first air flue 2 including being arranged.Also
It is located at the internal thread 22 outside valve box 1 in the second gas 3 including being arranged.
Operation principle：Aerating and exhaust device is arranged on the surface for being bullied component first, and the first air flue 2 is located at the outer of component of being bullied
Side, the second air flue 3 are located at the inside for component of being bullied.
Finger extruding gasbag 5 makes air bag 5 and 1 air pressure inside of the valve box being connected to air bag 5 become larger, inside valve box 1
With under the action of the pressure difference be bullied in component, for gas by the aperture of the second sieve plate 13, pressing to the second valve block 7 makes the second valve block 7
Overcome the elastic pulling force of the second valve shaft 15 that second valve block 7 is open-top, the gas inside air bag 5 is by third air flue 4, valve at this time
Door room 1, the second air flue 3 are supplied gas to component of being bullied.When 1 inside of valve box and the pressure for components interior of being bullied balance again
When, the second valve block 7 loses the air pressure thrust that is provided by valve box 1, and is retracted by the elasticity of the second valve shaft 15 and close the
Two air flues 3 prevent the gas being bullied in component to be back in valve box 1 through the second air knife 3.
When finger unclamps air bag 5, air bag 5 is based on own material properties elastic recovery, and 1 internal pressure of valve box drops at this time
It is low, and in 1 inside of valve box under the effect of outside atmosphere pressure difference, aperture of the extraneous air through the first air flue 2, the first sieve plate 10 makes
The first valve block 6 is pressed to, and the first valve block 6 is made to overcome the elastic pulling force of the first valve shaft 12 and inwardly raise, air is through at this time
One air flue 2, valve box 1, third air flue 4 can smoothly enter into air bag 5, when air bag 5 restores completely and is full of air, valve box 1
It is balanced with external pressure, the first valve block 6 loses air pressure thrust, and is retracted by the elasticity of the first valve shaft 12 and close the first gas
Road 2 prevents gas in valve box 1 from releasing valve box 1 through the first air flue.After air bag 5 restores completely, it can be squeezed again by finger
The mode of pressure carries out above-mentioned working cycles, to the purpose for the component inflation that is embodied as being bullied.
When needing to discharge the components interior pressure and when being adjusted of being bullied, release button 18, release button 18 only need to be pressed
Pressing thrust is successively by force inwardly jacked up the first valve block 6 through first support bar 17,16 body of the first support base completely, while the
One valve shaft 12 is stretched by force, and generates rebound potential energy.Due to the travel settings of jack-up, after the first valve block 6 jacks up completely, connect
Second support bar 20 is touched, and pressing thrust is passed into the second valve block 7 through second support bar 20, the second support base 19 successively, is made
Second valve block 7 is opened by force, while so that the second valve shaft 15 is stretched by force and being generated rebound potential energy.It is bullied at this time component, valve
Door room 1 be connected to outside atmosphere, the gas for component of being bullied under pressure, through the second air flue 3, valve box 1 and the first air flue 2
It discharges and loses heart.
In pressing button 18 by finger and carrying out pressure releasing process, when being bullied, components interior pressure reaches target call
When, finger release button 18, button 18,17 ineffective power of first support bar, the elastic potential energy of the first valve shaft 12 turn at this time
Chemical conversion kinetic energy carry out retraction movement, by the first valve block 6 playback sealing its corresponding to the first air flue 2, while pass through first support
Seat 16,18 pushed home of first support bar 17 and button.Since second support bar 20 has lacked the pressure from the first valve block 6,
The elastic potential energy of second valve shaft 15 is converted to kinetic energy and carries out retraction movement, by the second valve block 7 playback sealing corresponding to it the
Two air flues 3, while by support base 19,20 pushed home of first support bar.
In use, although air bag 5 can rely on the rebound characteristics of own material to carry out recovery air-breathing, by gas
Capsule 5 restores the flow restriction of dynamics and air intake duct 2, and air-breathing speed is slower, in order to make up this defect, improves service efficiency,
Therefore addition convexity spring is supported again on the Impact direction inside air bag 5, and the recovery after the pressing release of auxiliary balloon 5,
Enhance its gettering ability.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
Equivalent replacement is carried out, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
