It further include valve seat 6 in the present embodiment, the valve seat 6 is arranged between the connection cover 53 and leather cup 52.The utility model
In, noise reduction device 3 is equipped in the gas vent 22 of the air pump main body 2, in the present embodiment, the noise reduction device 3 includes
The piston cap 31 of 22 lower port of gas vent and the piston 32 of 31 corresponding matching of piston cap are set, and setting exists
One end of return springs 33 on the piston 32, the return springs 33 is connect with piston 32, the return springs
33 other end withstands on 22 inner wall of gas vent, by the on-off for the gas being discharged from piston cap 31 so that the Flexible Reset
The control piston 32 of part 33 upwards or moves downward in the gas vent 22.
The present embodiment is as follows in the specific course of work: open asepwirator pump, under the action of motor 1, swinging mounting 42 into
Row circle swing, under the action of eccentric wheel 41, the corresponding diastole compression chamber 520 of the leather cup 52 of one at least within
Diastole, and the diastole compression chamber 520 of diastole is since air pressure inside reduces, corresponding to the second valve 55 then open, described the
One valve 54 is then closed, at this time, it may be necessary to then pass through air inlet 21 into asepwirator pump by the gas in the equipment of air-breathing, is successively passed through
The path of c-d-e-f-h, and entered in the diastole compression chamber 520 of the diastole by second valve 55, at this time described
Under the elastic reaction of return springs 33, the piston 32 is fitted close with the piston cap 31；And when described with swing
Bracket 42 continues to swing, and diastole compression chamber 520 then gradually by the state of diastole, becomes the state of compression, at this point, with being compressed
Diastole compression chamber 520 due to air pressure inside increase, corresponding to the second valve 55 then close, first valve 54 is then beaten
It opens, at this point, the gas in the diastole compression chamber 520 is then arrived from 54 outlet of the first valve by the direction as shown in Fig. 3 arrow g
Up in gas vent 22, the air pressure in gas vent 22 increases, and the piston 32 is pushed under the influence of air pressure, compresses described multiple
Position elastic component 33 moves upwards, and the gap between the piston 32 and the piston cap 31 increases at this time, and gas is then from the work
Gap between plug 32 and the piston cap 31 is discharged, when needing the gas in equipment by air-breathing to be sucked fastly, from described
The gas come out in diastole compression chamber 520, at this point, this few gas reaches in the gas vent 22, is arranged at this time with regard to considerably less
Air pressure change in stomata 22 is little, and insufficient pressure enough pushes the piston 32 open, therefore, piston 32 then tightly with the piston
Lid 31 is fitted close, and the gas vent 22 is closed, at this point, the mechanical movement noise in asepwirator pump is got lodged in asepwirator pump by piston 32
Inside, to have the function that reduce load noise.
The utility model can also be set as second of embodiment (as shown in Fig. 7 to Figure 12), second embodiment with
The first embodiment is substantially the same, the difference is that the noise reduction device 3 includes being arranged in the gas vent 22
Air pressure gun body 34 at lower port, is equipped with software flow-stop valve 35 on the air pressure gun body 34, and the air pressure gun body (34) offers muzzle
(340) against software flow-stop valve inner hole (350), the software flow-stop valve inner hole (350) by by muzzle gas on-off by
Control opens or closes.In the present embodiment, specifically, working as one of those described corresponding diastole compression chamber of the leather cup 52
When 520 diastole, similarly, gas is simultaneously entered in the diastole compression chamber 520 of the diastole by second valve 55, at this time institute
The inner hole 350 of software flow-stop valve 35 is stated in closed state；And when described as swinging mounting 42 continues to swing, diastole compression chamber
520, then gradually by the state of diastole, become the state of compression, at this point, similarly, gas in the diastole compression chamber 520 then from
First valve, 54 outlet reaches in gas vent 22 by the direction as shown in Fig. 9 arrow g, and the air pressure in gas vent 22 increases
Greatly, the muzzle 340 that biggish air-flow then passes through the air pressure gun body 34 blows to the inner hole 350 of the software flow-stop valve 35, at this point, institute
The inner hole 350 for stating software flow-stop valve 35 is blown open, and gas is gone out from the inner hole 350 of software flow-stop valve 35, when needs are by air-breathing
When gas in equipment is sucked fastly, the gas come out from the diastole compression chamber 520 is with regard to considerably less, at this point, this is few
Gas reaches in the gas vent 22, and the air pressure change at this time in gas vent 22 is little, and the insufficient pressure of air-flow enough blows open described
The inner hole 350 of software flow-stop valve 35, therefore, the inner hole 350 of software flow-stop valve 35 are then closed up tightly, and the gas vent 22 is close
It closes, at this point, closed software flow-stop valve 35 gets lodged in the mechanical movement noise in asepwirator pump inside asepwirator pump, to reach reduction
The effect of load noise.
In the present embodiment, the inner hole 350 of the software flow-stop valve is arranged to the cone that aperture becomes smaller from air inlet end to outlet side
Shape structure further for focused airflow, increases stream pressure, the muzzle 340 of the air pressure gun body 34 is arranged to bore by entering
The pyramidal structure that gas end becomes smaller to outlet side, the inner hole at the center of the muzzle 340 of the air pressure gun body 34 and the software flow-stop valve
350 center is on same central axes.Air-flow can be more intensively utilized in this way, it more rapidly and easyly will be described
The inner hole 350 of software flow-stop valve 35 is blown open.
