Detailed description of the invention
Technical scheme is described in detail below with reference to drawings and the specific embodiments, in order to become apparent from,
Understand the invention essence of the present invention intuitively.
Fig. 1 is the cross section structure schematic diagram of the present invention structure improved respirator air flue；
Shown in Fig. 1, one provided by the present invention structure improved respirator air flue, mainly apply
In respirator, its objective is with so that in the unit interval, increasing the throughput of gas；
Specifically, one provided by the present invention structure improved respirator air flue, including pneumatic duct 10,
The getter device 20 being fixed in pneumatic duct 10, described getter device 20 is in pneumatic duct 10 air-flow input side
To one end be provided with an air inlet 30, and described getter device 20 is in pneumatic duct 10 air-flow outbound course
One end is provided with a gas outlet 40, and the present invention is improved by: the edge of described air inlet 30 and gas outlet
The edge of 40 respectively around described air inlet 30 and gas outlet 40 be provided with one outwardly whirlpool type water conservancy diversion dress
Putting, each described whirlpool type guiding device is one-body molded with the inwall of described pneumatic duct 10 respectively.
So, when the air-flow input of pneumatic duct 10 inputs air-flow, by the whirlpool type at air inlet 30
The guide functions of guiding device, can make inputted air-flow can quickly flow into described air inlet 30,
Further, by the shunting action of the whirlpool type guiding device at gas outlet 40, can make from gas outlet 40
The air-flow of place's output can quickly shunt and export the outfan to pneumatic duct 10, thus, the present invention uses
Effective.
Further, it should be noted that in the present embodiment, the appearance of each described whirlpool type guiding device
Face is arc convex structure 50 outwardly, and each described arc convex structure 50 includes that one is convex respectively
Play face 501 and the smooth surface 502 seamlessly transitted with described crowning 501.
Further, in the present embodiment, it is positioned at the smooth surface of the arc convex structure 50 of air inlet 30 one end
502 be located adjacent to described air inlet 30, and tangent with the inwall of described air inlet 30；It is positioned at and gives vent to anger
The crowning 501 of the arc convex structure 50 of mouthful 40 one end be located adjacent to described gas outlet 40, and
Tangent with the inwall of described gas outlet 40.
Herein, it is to be understood that be positioned at the crowning of the arc convex structure 50 of air inlet 30 one end
501 be located adjacent to air-flow input, be positioned at arc convex structure 50 smooth of one end, gas outlet 40
Face be located adjacent to air-flow outfan.
So, i.e. make each described arc convex structure 50 in airfoil type, according to hydromechanical principle
Understand, be positioned at pneumatic duct 10 air pressure inside at the described smooth surface 502 of air inlet 30 side and be less than
Pneumatic duct 10 outside atmosphere air pressure, thus, produce negative pressure at smooth surface 502, form vacuum state,
And then, when the airflow passes smooth surface 502 that the air-flow input of pneumatic duct 10 is inputted, almost without
Resistance so that the throughput flowed through was greatly increased within the unit interval, further such that the present invention uses effect
Fruit is more preferably.
And when being embodied as, the curved surface length of each described smooth surface 502 is all higher than being adjacent position
The end face length of described lobe.
Thus, the air-flow in pneumatic duct 10, whether air-flow input or air-flow outfan, accordingly
Air-flow all can be good at being seamlessly transitted by smooth surface 502, and, in practice it has proved that, Mei Gesuo
State the curved surface length of smooth surface 502 the longest time, produced effect also can be the best.
And it should be noted that the getter device 20 in traditional related airway pipe 10 is provided with one
Impeller, is promoted the flowing of air-flow, and in the present embodiment, is provided with two by the rotation of an impeller
Impeller, concrete, described getter device 20 includes driving motor 201 and being fixed on driving motor 201
Vortex impellers in rotary shaft, described vortex impellers includes absorbing impeller 202 and exhaust impeller 203, described
Absorbing impeller 202 is positioned at described air inlet 30 side, and described exhaust impeller 203 is positioned at described gas outlet 40
Side；
So, when absorbing impeller 202 rotates, carry out air-breathing, when exhaust impeller 203 rotates, it is simple to row
Gas, thus, by absorbing impeller 202 and the common effect of exhaust impeller 203, can promote to accelerate gas
Flow velocity, further such that using effect of the present invention is more preferable.
In sum, one provided by the present invention structure improved respirator air flue, at traditional air flue
The inwall of pipe 10, has additional one at the air inlet 30 and gas outlet 40 of relevant getter device 20 respectively
Whirlpool type guiding device, when the air-flow input of pneumatic duct 10 inputs air-flow, at air inlet 30
The guide functions of whirlpool type guiding device, can make inputted air-flow can quickly flow into described air inlet
Mouth 30, and, by the shunting action of the whirlpool type guiding device at gas outlet 40, can make from giving vent to anger
At mouth 40, the air-flow of output can quickly shunt and export the outfan to pneumatic duct 10, thus, this
Bright using effect is good.
Meanwhile, the outer surface of each described whirlpool type guiding device of the present invention is arc outwardly
Shape bulge-structure 50, each described arc convex structure 50 includes a crowning 501 and convex with described respectively
Play the smooth surface 502 that face 501 seamlessly transits, so, i.e. make each described arc convex structure 50
In airfoil type, according to hydromechanical principle, it is positioned at the pneumatic duct 10 at smooth surface 502 internal
Air pressure is less than pneumatic duct 10 outside atmosphere air pressure, thus, produce negative pressure at smooth surface 502, formed true
Dummy status, and then, airflow passes air inlet 30 side inputted from the air-flow input of pneumatic duct 10
Smooth surface 502 time, almost without resistance so that the throughput flowed through was greatly increased within the unit interval,
Further such that using effect of the present invention is more preferable.
And the present invention is in the specific implementation, it is not required to increase too many cost, the unit interval can realized
While the effects such as interior, air-flow velocity is fast, throughput increase, also can make to be effectively improved the present invention's
Service efficiency, and reduce the power consumption etc. of associated drive motor 201, thus, the present invention necessarily has very well
Market popularization value, can the most welcome, can effectively be popularized.
Further, the structural improvement of the pneumatic duct 10 of the present invention, it is used not only for respirator field,
It can be additionally used in other correlative technology fields, the drinking-water pipe etc. drawn water such as suction pump, here, do not do one
One illustrates.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention,
Every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion, or directly
Or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
