The specific embodiment
Below be further elaborated based on the specific embodiment of accompanying drawing to the utility model.Should be appreciated that specific embodiment described herein only as embodiment, and be not used in the protection domain that limits the utility model.
See also Fig. 3 and Fig. 4, be a kind of drifting dust head 10 that present embodiment provided with spherical location.Said drifting dust head 10 comprises that 12, one at second nozzle that 11, one at one first nozzle is arranged on said first nozzle 11 is arranged on the spring 13 in second nozzle 12, and a ball 14 that is arranged in said first nozzle 11.In the present embodiment, said first nozzle 11 is connected with snap fit with second nozzle 12.Said spring 13 is used for said ball 14 is replaced to first nozzle 11 to locate said first, second nozzle 11, relative position between 12.
Said first nozzle 11 comprises one first body 111; Four first siphon port 112 that are arranged on this first body 111; 113, one of an internal thread hole of jet end that are used to connect air drifting dust rifle (figure do not show) that are arranged on these first body, 111 1 ends is arranged on the double-screw bolt 114 that is used to connect second nozzle 12 of the other end of said this first body 111.Said first siphon port 112 is opened on the sidewall of said first body 111, is evenly distributed with four first siphon port 112 in the present embodiment.What can expect is that a plurality of these first siphon port 112 arbitrarily can be set as required.The shape of this first siphon port 112 can be made as triangle, oval hole shape, circle, square or other various geometries on demand, and size also is able to suitably change, and looks demand fully and changes.When said first nozzle, 11 jet flows go out swiftly flowing compressed air; Air storage capacity with the flow consumed cabin air compressor of 150 liters of per minutes; When these first nozzle, 11 jet flows go out the air of low-voltage high speed; First siphon port 112 around this first nozzle 11 forms vacuum states, sinks the air of first siphon port, 112 external high pressures, and a large amount of air flow into compressed air with high speed jet in first nozzle, 11 internal mix jet flows by first siphon port 112; Thereby increase the flow of air-flow, and then increase dust removing effects.The diameter of the cross section of the screw thread of said double-screw bolt 114 and ball 14 is suitable, and being beneficial to ball 14 can be threaded into said double-screw bolt 114 in second nozzle 12 around this screw thread.Said first siphon port 112 has a upwind leg 116 near a side of second nozzle 12, and the normal direction of this upwind leg 116 and outside air flow into the in the opposite direction of first nozzle 11.
Please consult Fig. 5, Fig. 6 in the lump, the side near first siphon port 112 of said double-screw bolt 114 is provided with a through hole 115.The diameter of this through hole 115 is less than or equal to the diameter of said ball 14, is used for the part that ccontaining said ball exposes second nozzle.At the diameter of this through hole 115 during less than the diameter of said ball 14, the part of must said ball 14 exposing second nozzle 12 is placed in this through hole 115 fully and is advisable.This through hole 115 is arranged on the axis of one of them first siphon port 112.
Please consult Fig. 3 and Fig. 4 again, said second nozzle 12 comprises that 121, one of one second bodies are arranged on the joint end 122 of these second body, 121 1 sides, and at least one is arranged on second siphon port 123 between said second body 121 and the joint end 122.In order to enlarge the dedusting area of this nozzle 10, the diameter of said second body 121 is greater than the diameter of said joint end 122, thereby makes second siphon port 123 be arranged on the inclined-plane.In order to make each first siphon port 112 corresponding with second siphon port 123, the quantity of this second siphon port 123 equates with the quantity of first siphon port 112.The free end side of said joint end 122 is provided with a counterbore 124.This counterbore 124 the diameter of porch less than the diameter of said ball 14, with these ball 14 interference fit.This counterbore 124 is except that the diameter of porch, and the diameter of the aperture of remainder and ball 14 is suitable.Said counterbore 124 is arranged on the axis of any one first siphon port 112, so that said first siphon port 112 is alignd with the axis of corresponding second siphon port 123 respectively.With first siphon port 112; Said second siphon port 123 has identical effect with first siphon port 112; This second siphon port 123 has a limit 125 with the wind near a side of first siphon port 112 simultaneously; Normal direction on limit 125 is identical with the direction that outside air flows into first nozzle 11 with the wind for this, and this with the wind the length D2 on limit 125 equate with the length D1 of upwind leg 116.Because first siphon port 112 is near the upwind leg 116 of second siphon port, 123 1 sides and second siphon port 123 equal in length near the limit with the wind 125 of first siphon port, 116 1 sides; Make at this upwind leg 116 and the air-flow width that gets on the limit 125 with the wind consistent; Thereby can reduce from of the interference of first siphon port, 112 inhaled airs stream, and then can avoid reducing arrival by the air-flow of dedusting face to forming from second siphon port, 123 inhaled airs stream.
The diameter of the porch of the external diameter of said spring 13 and counterbore 124 is suitable, is beneficial to this spring 13 is inserted in this counterbore 116.The length of this spring 13 is can replace said ball 14 and to have certain decrement to be advisable.
The inside diameter of the diameter of said ball 14 and counterbore 124 is suitable.Because ball 14 is interference fit with the porch of counterbore 124, when assembling, need this ball 14 is pressed into by external force in the said counterbore 124.Simultaneously,, after this ball 14 is pressed in the counterbore 124, can from this counterbore 124, not drop out, can not replaced out simultaneously yet by said spring 13 because the porch of ball 14 and counterbore 124 is interference fit.
Owing to have spring 13 and ball 14 on said second nozzle 12; And first detent mechanism that constitutes of through hole 115 on the nozzle 11; When said first nozzle 11 and second nozzle 12 are assembled; The part that said ball 14 exposes joint end 122 madial walls is placed in this through hole 115 fully, and four first siphon port 112 of first nozzle 11 and four siphon port 123 of second nozzle 12 are aligned, thereby can avoid in first, second siphon port 112, form sinuous flow in institute's inhaled air stream between 123; And the phase mutual interference, and then avoid reducing arrival by the air-flow of dedusting face.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Interior any modification of doing of all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included in the utility model protection domain in.
