In the course of the work, compression piston bar 10, adjustment piston rod 31 pump in bullport.The air inlet 8 arranging at end cap is communicated with respectively compression cylinder barrel 9, controls cylinder barrel 32 and main chamber 1, is convenient to compression piston 11, adjusts piston 30 in the time pumping, and air enters compression cylinder barrel 9, controls cylinder barrel 32, reduces resistance.On compression piston 11, be provided with Non-return air valve, also can be other similar structures, for example: have through hole 12 at compression piston 11, on through hole 12 tops, skin valve 13 is installed, in the time that compression piston 11 moves down, skin raft 13 is opened, compression air chamber's 40 air inlets, while moving on compression piston 11, skin valve 13 seals through hole 12, and the air in compression air chamber 40 is compressed.
Particularly, the work process of the described portable dental scaler that dusts is divided into three phases, compression stage, jet stage, charging stage.
Compression stage:
Open gauge tap, switch on power, micro-driving motor 3 rotates, and drives compression cam 5 and controls cam 35 and rotate.Compression cam 5 and control cam 35 are converted to compression piston bar 10, adjust the reciprocating motion of piston rod 31 rotatablely moving by roller 33.As shown in Figure 4, in the time that on compression cam 5, A point contacts with the roller 33 on compression piston bar 10, compression piston 11, in lower dead center, compresses air cavity 40 volume maximums.Compression cam 5 rotates, compression segmental arc involute
radius of curvature increases gradually, and roller 33 promotes to move on piston 11, compressed air, until the B of maximum curvature radius place point, air compressing is than maximum, and volume of air is dwindled 2.5～3 times, and air pressure increases between 0.2～0.3Mpa, as shown in Figure 7.Have fixing phase matched relation owing to controlling between cam 35 and compression cam 5, in this process, compression cam 5 forwards D point to from A point, and control cam 35 and forward F point to from H point,
radius of curvature is definite value, adjusts piston 30 at the top dead centre of controlling air chamber 41.Adjusting piston 30 seals pore 16.Thereby air compresses at the compression cylinder barrel 9 compressed pistons 11 in the inside.
The jet stage:
As shown in Figure 5, driving shaft 38 continues to drive compression cam 5 and controls cam 35 and rotate, and the roller 33 on compression piston bar 10 is from B → C → D with the track of compression cam 5 contact points, jet segmental arc
radius of curvature is definite value, and compression piston 11 keeps motionless at the top dead center position of compression cylinder barrel 9.And the roller 33 of adjusting on piston rod 31 is F → E → G with the track of controlling cam 35 contact points, as shown in Figure 8, in F and G point radius of curvature maximum, in E point radius of curvature minimum, thereby adjust piston 30 under the effect of spring 15, move down into rapidly the lower dead center of controlling air chamber 41, pore 16 is communicated with controls air chamber 41 and compression air chamber 40, compressed air, from compression air chamber 40 to controlling air chamber 41, sprays and enters spraying system through nozzle 29.After aerojet, the roller 33 of adjusting on piston rod 31 is point from E to G with the track of controlling cam 35 contact points, adjusts piston 30 rapidly from the lower dead center of controlling air chamber 41 to top dead centre, and pore 16 is sealed.
Charging stage:
As shown in Figure 6, compression cam 5 rotates, and the roller 33 on compression piston bar 10 is from D → A with the track of compression cam 5 contact points, air inlet segmental arc involute
radius of curvature reduce gradually, compression piston 11 moves down from the top dead centre of compression air chamber 40.Now, pore 16 is sealed, and the air pressure of compression air chamber 40 reduces, and air, through air inlet 8, compression cylinder barrel 9 and through hole 12, is pushed skin valve 13 open under pressure, enters into compression air chamber 40.When roller 33 on compression piston bar 10 reaches A point with compression cam 5 contact points, compression piston 11 arrives the lower dead center of compression air chamber 40, compression air chamber's 40 volume maximums, and the inside is full of the air equating with atmospheric pressure.As shown in Figure 9, in this process, control cam 35 and rotate, the roller 33 of adjusting on piston rod 31 is from G → H with the track of controlling cam 35 contact points,
arc with
radius of curvature equates, adjusts piston 30 and remains on the top dead centre of controlling air chamber 41 always, sealing pore 16.
So move in circles, realize compressed air and continue to enter spraying system, ejection dentifrice, cleaning teeth.
This described embodiment is preferred embodiment of the present invention; but invention is not limited to above-mentioned embodiment; in the situation that not deviating from technical scheme of the present invention, any apparent improvement, replacement or modification that those skilled in the art can make all belong to protection scope of the present invention.
