The right contact of piston 6 simultaneously promotes right riser to overcome the elastic force of the first right stage clip 27 to move right, and right riser drives right transverse slat to the right
Mobile until exiting the horizontal blind hole 17 of right fixture block 24 completely, now right neck 14 is just moved to the right top of fixture block 24, the
Right flat board 28, which is upspring, in the presence of two right stage clips 29 promotes the right ejection of fixture block 24 to stick into right neck 14, and piston 6 is positioned at into this
Position, complete the switching of the position of piston 6；After piston 6 is switched to right position, the upper aperture of left through hole 7 and the dislocation closing of air admission hole 3,
Lower aperture is relative with steam vent 4 so as to connect, and left chamber, which can only be vented, is unable to air inlet, while the air admission hole 3 in left side is by piston 6
Surface-closed, the upper aperture of right through hole 8 are connected with the air admission hole 3 on right side, and lower aperture and the dislocation closing of steam vent 4, right chamber room is only
Air inlet can not be vented, so as to realize the switching of left and right chamber air intake-exhaust；Gas in left chamber under the influence of air pressure via
Left conduit, left through hole 7, steam vent 4 and gas distribution plate 5 spray, while gas distribution plate 5 rotates and realizes that the alternating of blast pipe is connected and closed
Close, one one ejection of gas enters in expectoration vest, so as to realize the vibration of expectoration vest；In the same of left chamber's exhaust
When, air inlet in right chamber room, the exhaust velocity of left chamber and the intake velocity of right chamber room are arranged to synchronized, so left chamber intraventricular pressure is strong
It is gradually reduced, the pressure of the columnar projections upper end on left plate 20 is gradually reduced, and pressure is gradually increasing in right chamber room, and air pressure passes through
Right air flue 31 is reached in right blind hole 30 and acted in the columnar projections on right flat board 28, as the air pressure in right chamber room gradually increases
Greatly, the pressure acted in columnar projections gradually increases, and right flat board 28 can overcome the elastic force of the second right stage clip 29 to move gradually downward
Dynamic, so as to pull right fixture block 24 to move downward, until right fixture block 24 exits outside right neck 14 completely, now right fixture block 24 no longer limits
Position piston 6, because the air pressure in right chamber room is more than the air pressure in left chamber, pressure differential will pass through left guide pillar 9 and right guide pillar 10
End-acted on piston 6, piston 6 moves to left in the presence of the pressure difference of left and right, and while piston 6 moves to left, right montant 26 is first
It is moved to the left, is inserted so as to drive right cross bar 25 to move to left in the horizontal blind hole 17 of right fixture block 24, by the right side in the presence of right stage clip 27
Fixture block 24 is locked to prevent it from ejecting in this position；When piston 6 is moved to the leftmost side soon, the left contact of piston 6 simultaneously promotes left perpendicular
Plate overcomes the elastic force of the first left stage clip 19 to be moved to the left, and left riser drives left transverse slat to be moved to the left until exiting left fixture block 15 completely
Horizontal blind hole 17, now left neck 13 be just moved to the top of left fixture block 15, now due to the pressure in the columnar projections of left side
As the exhaust of left chamber is already less than the elastic force of the second left spring, left plate 20 is upspring in the presence of the second left stage clip 21,
The left ejection of fixture block 15 is sticked into left neck 13, and piston 6 is positioned at into this position, the switching of the position of piston 6 is completed, realizes left chamber
Gas is stored, right chamber vent, so circulation realize pressurization and exhaust of the gas in the chamber of left and right, continual while pressurization
Vibration pneumatic is provided for expectoration vest.
Pressure when being discharged to the gas in regulation left and right chamber, then adjust left by-path 32 and right branch by action bars 35
The opening and closing of ball valve 34 in road 33 are so as to select to ventilate above which columnar projections, the cross section of the columnar projections of ventilation
Product is smaller, and the active area of air pressure is smaller, then in the case that the elastic force of stage clip is constant under flat board, promotes flat board to move down required
Pressure is bigger, i.e., make in the chamber of left and right fixture block exit neck air pressure it is higher, namely piston 6 switch when chamber in pressure get over
Greatly, conversely, the cross-sectional area of the columnar projections of ventilation is bigger, chamber inner pressure is smaller by force when piston 6 switches；Therefore behaviour need to only be passed through
Making bar 35 controls the ball valve 34 on different by-paths to be turned on and off, you can which columnar projections work is selected, so as to adjust discharge
The pressure of gas；Furthermore it is also possible to make the multiple ball valves 34 of homonymy while open further to reduce when piston 6 switches in chamber
Pressure, therefore by selecting the cooperation of different columnar projections and its quantity that the purpose of multi-gear adjustment pressure can be achieved, with
Meet the requirement of different users and service condition.
Frequency to adjust Gas Vibration, turning for gas distribution plate 5 is adjusted by adjusting the rotating speed of the motor of gas distribution plate 5
Speed, the frequency for being turned on closing are accelerated or reduced, you can adjust the frequency of vibration pneumatic；To ensure the balance of air intake-exhaust,
Need for the rotating speed of air pump to be transferred to the rotating speed to match with gas distribution plate 5 while 5 rotating speed of gas distribution plate is adjusted.
The present invention has following significantly advantage：
Small volume of the present invention, it is light portable；This is bright to have abandoned existing drive air film to vibrate by mechanical reciprocation completely
The mode of vibration pneumatic is produced, employs a kind of new way, that is, the gas batch (-type) after being pressurized, which sprays, produces vibration pneumatic；
