Journey.
When piston 6 is located at left position, the left ejection of fixture block 15 is sticked into the left neck 13 of the bottom surface of piston 6, prevents piston 6 from moving
Dynamic, right cross bar 27, which is inserted in the horizontal blind hole 17 of right fixture block 26, prevents right fixture block 26 from ejecting, the upper hole of left through hole 7 on piston 6
Mouthful and the air admission hole 3 of the upper left side of housing 1 communicate, lower aperture and steam vent 4 misplace so as to close, and the upper surface of piston 6 is by right side
Air admission hole 3 is closed, and the upper aperture of right through hole 8 and air admission hole 3 misplace so as to close, and lower aperture and steam vent 4 communicate, and now start
The motor of air pump, air pump are pumped into gas into air inlet pipe, and gas enters housing 1 via air inlet pipe, left through hole 7 and left cross-drilled hole 11
In left chamber, due to the lower orifice closing of left through hole 7, left chamber can only air inlet can not be vented, with being pumped into for gas, left chamber
Interior air pressure rise, air pressure act on the bottom of left plunger 25 by the first left 23 and second left air flue 24 of air flue and promote left post
Plug 25 moves up, and left plunger 25 jacks up the left end of lever left 20, the right-hand member of lever left 20 is overcome the elastic force of the second left stage clip 22
Move downward, the right-hand member of lever left 20 moves downward through T-slot 21 and drives left fixture block 15 to move downward, with the gas in left chamber
Pressure gradually rises, and air pressure pulls left fixture block 15 gradually to move down by left plunger 25 and lever left 20, until left fixture block 15 moves back completely
Go out outside left neck 13, now left fixture block 15 no longer limiting piston 6, because the air pressure in left chamber is more than the air pressure in right chamber room,
Pressure differential by by left guide pillar 9 and right guide pillar 10 end-acted, on piston 6, piston 6 moves to right in the presence of the pressure difference of left and right,
While piston 6 moves to right, left montant 18 moves right in the presence of the first left stage clip 19, slotting so as to drive left cross bar 16 to move to right
In the horizontal blind hole 17 for entering left fixture block 15, prevent it from ejecting in this position by left fixture block 15 is locked；Piston 6 is moved to most right soon
During side, the right contact of piston 6 simultaneously promotes right riser to overcome the elastic force of the first right stage clip 29 to move right, and right riser drives right transverse slat
Move right until exiting the horizontal blind hole 17 of right fixture block 26 completely, now right neck 14 is just moved to the right top of fixture block 26,
The right left end of lever 30 is upspring in the presence of the second right stage clip 31, and the right ejection of fixture block 26 is sticked into right neck 14, and piston 6 is positioned
In this position, the switching of the position of piston 6 is completed；After piston 6 is switched to right position, the upper aperture of left through hole 7 and the dislocation envelope of air admission hole 3
Close, 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 upper table face closures, the upper aperture of right through hole 8 are connected with the air admission hole 3 on right side, lower aperture and the dislocation closing of steam vent 4, right chamber room
Air inlet can not be vented, so as to realize the switching of left and right chamber air intake-exhaust；Gas in left chamber passes through under the influence of air pressure
Sprayed by left conduit, left through hole 7, steam vent 4 and gas distribution plate 5, 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
Be gradually reduced, the pressure of the lower section of left plunger 25 is gradually reduced, and pressure is gradually increasing in right chamber room, the pressure of the lower section of right plunger 34 by
Edge up height, and air pressure promotes right plunger 34 to move up, and right plunger 34 jacks up the right-hand member of right lever 30, overcomes the right left end of lever 30
The elastic force of second right stage clip 31 moves downward, and the right left end of lever 30 moves downward through T-slot 21 and drives right fixture block 26 to transport downwards
Dynamic, as the air pressure in right chamber room gradually rises, air pressure pulls right fixture block 26 gradually to move down by right plunger 34 and right lever 30,
Until right fixture block 26 exits outside right neck 14 completely, now right fixture block 26 no longer limiting piston 6, because the air pressure in right chamber room is big
In the air pressure in left chamber, pressure differential is by by the end-acted on piston 6 of left guide pillar 9 and right guide pillar 10, and piston 6 is in left and right
Being moved to left in the presence of pressure difference, while piston 6 moves to left, right montant 28 is moved to the left in the presence of the first right stage clip 29, so as to
Drive right cross bar 27 to move to left to insert in the horizontal blind hole 17 of right fixture block 26, prevent it from bullet in this position by right fixture block 26 is locked
Go out；When piston 6 is moved to the leftmost side soon, the left contact of piston 6 simultaneously promotes left riser to overcome the elastic force of the first left stage clip 19 to the left
Mobile, left riser drives left transverse slat to be moved to the left until exiting the horizontal blind hole 17 of left fixture block 15 completely, and now left neck 13 is being just
The left top of fixture block 15 is moved to well, now because the pressure of the left lower section of plunger 25 is as the exhaust of left chamber is already less than second left side
The elastic force of spring, the right-hand member of lever left 20 is upspring in the presence of the second left stage clip 22, and the left ejection of fixture block 15 is sticked into left neck 13,
Piston 6 is positioned at this position, completes the switching of the position of piston 6, realizes that left chamber stores gas, right chamber vent, so circulation are real
Existing pressurization and exhaust of the gas in the chamber of left and right, it is continual while pressurization to provide vibration pneumatic for expectoration vest.
Pressure when discharging to the gas in regulation left and right chamber, then need to change the left plunger 25 of actual participation work
With right plunger 34, plunger is closer to the fulcrum of lever, and its torque is shorter, then the elastic force of its stage clip for overcoming the lever other end jacks up
Power needed for lever is bigger, and required air pressure is bigger below accordingly, i.e., pressure when piston 6 switches in chamber is bigger, instead
It, plunger is more remote from fulcrum, and chamber inner pressure is smaller by force when piston 6 switches；Therefore only different plungers need to be controlled by action bars 36
Under ball valve 35 be turned on and off, you can the work of which plunger is selected, so as to adjust the pressure of discharge gas；Furthermore it is also possible to
Make multiple plungers while work is further to reduce pressure when piston 6 switches in chamber, therefore pass through plunger position and quantity
Cooperation the purpose of multi-gear adjustment pressure can be achieved, to 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；
The present invention devises the chamber of left, center, right three, realizes that the inflation of left and right chamber is vented switching by moving left and right for piston, leads to again
Control condition and the power that lever and fixture block switch the air pressure in chamber as piston are crossed, realizes the automatic switchover of piston, from
And alternately inflation exhaust in the chamber of left and right is realized, gas realizes that batch (-type) is discharged after chamber is indoor supercharged by gas distribution plate, so as to
Expectoration vest is produced vibration, only need to improve casing rigidity, so that it may enough gas is filled with the shell space of very little, is being contracted
The fluence and intensity of vibration pneumatic is also ensured while small size.
The amplitude of vibration pneumatic, frequency are adjustable；The present invention along lever design can multiple plungers, cleverly using plunger from
The bigger characteristic of its more remote torque of balance pivot, regulation fixture block exits the strong size of chamber inner pressure needed for neck, so as to adjust
Gas pressure intensity when piston switches in chamber, realize pressure regulation during chamber vent, you can amplitude during regulation Gas Vibration
Intensity, moreover, by the combination of plunger quantity, adjustable extent is set further to increase；In addition, by adjusting the rotating speed of gas distribution plate i.e.
The frequency of adjustable gas vibration.
Present inventive concept is novel, and clever structure, volume is lightly portable, and amplitude-frequency is adjustable, and easy to adjust fast
