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 as just 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 combined siphon drifting dust mouth 10 that present embodiment provided.Said drifting dust mouth 10 comprises one first nozzle 11; Second nozzle 12 that is arranged on said first nozzle 11; Four 13, four of screw rods that are arranged in second nozzle 12 are arranged on the spring 14 in said second nozzle 12, and four push rods 15 that are arranged in said second nozzle 12.In the present embodiment, said first nozzle 11 is connected with snap fit with second nozzle 12.Said spring 14 is used for said push rod 15 is replaced to first nozzle 11 to locate said first, second nozzle 11, relative position between 12.Said screw rod 13 is used for said spring 14 is fixed on second nozzle 12 with push rod 15.
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 first clip-connecting rod 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.Said first siphon port 112 has a upwind leg 117 near a side of second nozzle 12, and the normal direction of this upwind leg 117 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 first clip-connecting rod 114 is provided with four through holes 116.The diameter of this through hole 116 less than, equal the diameter of said push rod 15, be used for the part that ccontaining said push rod 15 exposes second nozzle 12.At the diameter of this through hole 116 during less than the diameter of said push rod 15, the part of must said push rod 15 exposing second nozzle 12 is placed in this through hole 116 fully and is advisable.These four through holes 116 are separately positioned on the axis of four first siphon port 112, so that said first siphon port 112 is alignd with the axis of corresponding second siphon port 123 respectively.Said first clip-connecting rod 114 comprises that also four are arranged on this first clip-connecting rod, 114 outer surfaces, and the gathering sill 115 that is connected with said four through holes 116 respectively.
Please consult Fig. 3 and Fig. 4 again, said second nozzle 12 comprises that 121, one of one second bodies are arranged on second 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 second 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 second joint end 122 is provided with the tapped through hole 124 in four L shaped cross sections.This tapped through hole 124 the diameter of porch less than the diameter of remainder, thereby form said L shaped cross section.Said tapped through hole 124 is arranged on the axis of any four second siphon port 123.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 117.Because first siphon port 112 is near the upwind leg 117 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, 112 1 sides; Make at this upwind leg 117 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.
Said push rod 15 has axial step cross section, and the minor diameter of the diameter of an end and screw thread logical 124 is suitable, and the major diameter of the diameter of the other end and tapped through hole 124 is suitable, thereby forms a step push rod, is beneficial to be connected in the said L shaped tapped through hole 124.
The external diameter of said spring 14 is plugged in the said tapped through hole 124 to replace the large-diameter portion of said push rod 15.The length of this spring 14 is can replace said push rod 15 and to have certain decrement to be advisable.
The inside diameter of the diameter of said screw rod 13 and tapped through hole 124 is suitable; And be screwed onto in this tapped through hole 124; And be arranged on the opposite side with respect to push rod 15 of said spring 13, with the relative position of L shaped tapped through hole 124 fixing said push rods 15 with spring 14.
Owing to have four springs 14 and push rod 15 on said second nozzle 12; And first detent mechanism that constitutes of four through holes 115 on the nozzle 11; When said first nozzle 11 and second nozzle 12 are assembled; The part that said push rod 15 exposes second joint end, 122 madial walls is placed in this through hole 115 fully; Four first siphon port 112 of first nozzle 11 and four siphon port 123 of second nozzle 12 are aligned, simultaneously the relative position of fixing said first, second nozzle 11,12.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.
