Embodiment
About aforementioned and other technology contents, characteristics and effect of the present utility model, in detailed description, can clearly present below in conjunction with a preferred embodiment of accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, be a preferred embodiment of this novel ion gun silencing means, this ion gun 1 comprises a nozzle 100 in order to blowing out pressurised air, and one is installed on the nozzle 100 in order to reduce the silencing means 200 of compressed air discharge noise.
Silencing means 200 comprises a hollow tube 2 in order to engage with nozzle 100, and is arranged at one first keeper 3, one second keeper 4, a hollow webmaster 5 and a silencer element 6 in the hollow tube 2 respectively.In the present embodiment, this hollow tube 2 is to be made of a roughly cylindrical conductive material, it comprises a basal wall 21, one by basal wall 21 peripheries towards the right side axially extended leg 22, one air inlet 23 that defines and be positioned at basal wall 21 opposite ends and be connected by leg 22 with nozzle 100, and one be located at place in the middle of the basal wall 21 and the aperture gas outlet 24 less than air inlet 23 apertures, the contiguous air inlet of leg 22 inner surfaces 23 places are provided with an internal thread segment 221 in order to the external thread section (figure does not show) that is bolted in nozzle 100, leg 22 is provided with two first screws 222 that are positioned at opposite side and contiguous air inlet 23 places, and two second screws 223 that are positioned at opposite side and 24 places, contiguous gas outlet, these two first, second screw 222,223 in order to supply two first respectively, second screw 224,225 screw locks.
On the other hand, first keeper 3 also comprise one by second end 34 towards first end, 33 direction axial depressions and be surrounded on first groove 36 in the second hole portion, 352 outsides, again, second pedestal 32 has two the 3rd screws 321 that caved in and be connected with first groove 36 by outer surface opposite side radial inward respectively, but and three screw 322 of two screw locks in the 3rd screw 321.
As Fig. 1 and shown in Figure 4, when assembling silencing means 200, earlier hollow webmaster 5 two ends are embedded respectively in first, second groove 36,46 of first, second keeper 3,4, and with the 3rd, the 4th screw 322,422 respectively screw locks in the 3rd, the 4th screw 321,421, and three, the bottom of the 4th screw 322,422 presses on hollow webmaster 5 surfaces respectively, hollow webmaster 5 is fixed between first, second keeper 3,4, simultaneously, hollow webmaster 5 and define and make first perforation 35 and second, 45 gas flows that are connected 52 of boring a hole.
Then silencer element 6 is sheathed on hollow webmaster 5 outer surfaces, and the two end portions of silencer element 6 is sheathed on first, second keeper 3,4 second, the 4th pedestal 32,42 outer surfaces, after will assembling again first, second keeper 3,4, hollow webmaster 5 and silencer element 6 are disposed in the hollow tube 2 by the air inlet 23 of hollow tube 2, make the 3rd end 43 of second keeper 4 be resisted against the internal face of the basal wall 21 of hollow tube 2, and the 3rd hole portion 451 of second perforation 45 of second keeper 4 is corresponding to 24 places, gas outlet of hollow tube 2, and with first, second screw 224,225 difference screw locks are in first, second screw 222, in 223, and first, second screw 224,225 bottoms press on first respectively, second keeper 3,4 first, the 3rd pedestal 31,41 outer surfaces, make first, second keeper 3,4 are fixed in the hollow tube 2, promptly finish the assembling of silencing means 200.Behind the external thread section of nozzle 100 front ends, silencing means 200 can be locked on the nozzle 100 of ion gun 1 with internal thread segment 221 screw locks at the contiguous air inlets of hollow tube 2 23 places of the silencing means 200 after the assembling.Certainly, the utility model silencing means 200 is fixedly arranged on mode on the nozzle 100 not as limit, its also can arrange in pairs or groups hollow tube 2 contiguous air inlets 23 places (and internal thread segment 221 places of present embodiment) are designed to the card Parapet (figure does not show) that can cooperate with nozzle 100 etc., existing connected mode of ventilating body all can apply in the utility model.
Because when the nozzle 100 of ion gun 1 blows out compressed air, can flow in the gas flow 52 via first perforation 35 of first keeper 3, by the configuration of first perforation, 35 the first hole portion, 351 aperture convergents, can make compressed air enter that flow velocitys increase in the gas flow 52.After compressed air flow to gas flow 52, can flow to silencer element 6 via the through hole 51 of hollow webmaster 5, silencer element 6 can absorb compressed air and discharge the noise that the back is produced, when then compressed air is circulated to gas outlet 24 and discharges via second perforation 45 of second keeper 4, pass through the aperture convergent configuration of the 4th hole portion 452 of second perforation 45 again, the speed that compressed air is discharged increases, air pressure when discharging to keep compressed air, pass through the configuration of silencer element 6 simultaneously, the noise when discharging by the gas outlet 24 of hollow tube 2 to weaken compressed air.By the configuration of silencing means 200, via the reality test, the noise in the time of effectively the compressed air of ion gun 1 being discharged really is reduced to 75 decibels (db) by 110 decibels (db).
On the other hand, because hollow tube 2, first, second keeper 3,4 and hollow webmaster 5 are all conductive material, and silencer element 6 is an antistatic material, therefore the compressed air after the ionization that is blown out by ion gun 1, after gas outlet 24 discharges via silencing means 200, this compressed-air actuated degree of ionization can not produce change, and can keep the compressed-air actuated degree of ionization of being discharged by nozzle 100.
Conclude above-mentioned, the ion gun silencing means of present embodiment, this silencing means 200 is by the configuration of the first, the 4th hole portion 351, the 452 aperture convergents of first, second perforation 35,45, air pressure in the time of keeping the compressed air discharge, absorb compressed air by silencer element 6 simultaneously and discharge the noise that the back is produced, can reduce the noise after compressed air is discharged from gas outlet 24 effectively.In addition, be all conductive material by hollow tube 2, first, second keeper 3,4 and hollow webmaster 5, and silencer element 6 is the design of an antistatic material, can avoid the electric charge accumulation thereon, guarantee that the degree of ionization after compressed air is discharged from gas outlet 24 is unaffected, so can reach the desired purpose of the utility model really.
Yet the above, it only is preferred embodiment of the present utility model, can not limit practical range of the present utility model with this, be that every simple equivalent of doing according to the utility model claim scope and description changes and modifies, all still belong in the scope that the utility model patent contains.
