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, a kind of siphon with packing ring and detent mechanism 10 for present embodiment provides.Said nozzle 10 comprises one first nozzle 11; Second nozzle 12 that is arranged on said first nozzle 11; A screw 13 that is used for fixing said first, second nozzle 11,12, and an elastic washer 14 that is arranged between said first nozzle 11 and second nozzle 12.In the present embodiment, said first nozzle 11 is connected with snap fit with second nozzle 12.
Said first nozzle 11 comprises one first body 111; First siphon port 112 that is 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 insertion end 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 insertion end 114 comprises first tapped through hole 115 on the sidewall that is arranged on this insertion end 114.This first through hole 115 is along the radially setting of insertion end 114, and said screw 13 is used to be spirally connected.Said first tapped through hole 115 can be arranged on the axis of any one first siphon port 112, also can be arranged on the axis of the spacer bar 116 adjacent with this first siphon port 112.In the present embodiment, said first tapped through hole 115 is arranged on the axis of any one first siphon port 112.
Said second nozzle 12 comprises one second body 121; A sleeve 122 that is arranged on these second body, 121 1 sides; At least one is arranged on second siphon port 123 between said second body 121 and the sleeve 122, and madial wall that is arranged on said sleeve 122 and towards the gasket groove 126 of said second body 121.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 sleeve 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 sidewall of said sleeve 122 is provided with second through hole 124 that is used to hold said screw 13.With said first through hole 115, this second through hole 124 also can be arranged on the axis of any one second siphon port 123, also can be arranged on the axis of the spacer bar 125 adjacent with second siphon port 123.In the present embodiment, said second through hole 124 is arranged on the axis of any one second siphon port 123.What can expect is, said second through hole 124 also can be tapped through hole, with screw 13 bolts.In the present embodiment, said second through hole 124 also is a tapped through hole.With first siphon port 112, said second siphon port 123 has identical effect with first siphon port 112, repeats no more at this.The notch of said gasket groove 126 is towards the insertion end 114 of first nozzle 11, and less than the wall thickness of its width and insertion end 114.
Said screw 13 is arranged in said first tapped through hole 115 and second through hole 124, so that disassemble.Owing to have first tapped through hole 115, second through hole 124 that are used to locate said first nozzle 11 and second nozzle 12; And the detent mechanism that constituted of screw 13; When said first nozzle 11 and second nozzle 12 are assembled; Four first siphon port 112 of first nozzle 11 and four siphon port 123 of second nozzle 12 are aligned, the relative position of fixing said first, second nozzle 11,12 simultaneously, thus 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.When the effect of adding elastic washer 14 can guarantee that said resilient key 13 matches with through hole 115,124, can guarantee that also said insertion end 114 closely cooperates with sleeve 122 each other.
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.
