Specific embodiment
Advantages of the present invention is expanded on further below in conjunction with accompanying drawing and specific embodiment.
It is the structural representation after the liner 120 and overcoat 110 of air amplifier of the present invention 100 are combined with reference to Fig. 1 to Fig. 6
Figure.In the present invention, air amplifier 100 is included and inserted in overcoat 110 in an overcoat 110 and liner 120, liner 120, is formed
The air amplifier 100.In order to provide external compression air to air amplifier 100, overcoat 110 offers a through hole 111, should
Through hole 111 is connected inside external compressed air source and overcoat 110, to should through hole 111, its outlet side inside overcoat 110
The part of relative liner 120 is inwardly drawn in shape, the i.e. segment section of liner 120 is drawn in, forms one similar to bell-mouthed knot
Structure, then form a confined space 130 between furlling part and overcoat 110, the confined space 130 is connected with through hole 111, external compression
Air is transmitted to the confined space 130 from after the feeding of through hole 111.Meanwhile, after liner 120 is fixedly connected with overcoat 110, both
Between have gap 140, and the gap 140 connects with the air duct inside confined space 130 and liner 120 respectively, so that logical
Hole 111, confined space 130, gap 140 form a circulation passage for supplying external compression air circulation.In the embodiment, gap
The 140 air inlet ends 121 for being formed in liner 120, i.e., near the end of air inlet 150 in liner 120.Then in order to coordinate from gap
The air of 140 outflows, the rounded shape of inwall of the air inlet end 121 of liner 120, the design of the radiussed so that from gap 140
The air of middle outflow circulates along radiused surface, and along the direction flowing of air inlet 150 to gas outlet 160, so as in liner
120 are internally formed negative pressure, further increase the speed and air velocity of the suction of the inner air of liner 120.With conventional design institute not
With because compressed air needs the direction flowed with the inner air of reverse liner 120 in advance to flow to gap from confined space 130
140, then flowed out along fillet inwall from gap 140 with the direction of the forward inner air of liner 120 flowing, the fold back of the air flow
Design causes the air velocity flowed at fillet faster, which increases the Coanda effect (Coanda of the fluid at fillet
Effect)。
Simultaneously it is appreciated that because compressed air is flowed out by said flow passage, negative pressure is formed, near air inlet 150
Air suction, not only increase the speed of charge air flow, at the same also achieve increase air-flow purpose.
Further, refering to Fig. 5, liner 120 has internal thread, and overcoat 110 has external screw thread, and external screw thread is matched somebody with somebody with internal thread
Close so that liner 120 and the interference fit of overcoat 110, not only increase the tight fit degree of liner 120 and overcoat 110, and two
The closed relation of person is more preferably.
Optional or preferably, for obturation effect further between closed liner 120 and overcoat 110, the surface of liner 120 sets
There is a groove 122, and a sealing ring 123 is provided with the groove 122, when liner 120 is combined with overcoat 110, sealing ring 123
It is close to the inwall of overcoat 110 and the outer wall of liner 120 respectively, to completely cut off confined space 130.
Further, the overcoat 110 of air amplifier 100 has a supporting table 112, branch near the end of gas outlet 160
A centring ring 113 is set on support platform 112, the centring ring 113 is set in the outside of overcoat 110 and liner 120, for fastening outer sleeve
The combination of 110 end and liner 120.It is understood that the centring ring 113 is collapsible or extends out, when centring ring 113 shrinks
When, liner 120 and the part of overcoat 110 at centring ring 113 also will accordingly shrink, then the face of the flow area at gas outlet 160
Product reduces so that the air mass flow of outflow reduces, conversely, when centring ring 113 is extended out, the air mass flow increase of outflow.This can be received
The centring ring 113 for contracting or extending out using the structure design of elasticity, or supporting table 112 can be changed in the position of overcoat 110,
To reach the effect of the banding liner 120 of centring ring 113.
Further optional or preferably, the outer wall of overcoat 110 is provided with a retainer plate 114, can be with external component such as cooler
Bed connection, so that the position of fixed air amplifier 100.
Refering to Fig. 6, air amplifier of the invention 100 is clearly demonstrated in the structure decomposition figure by sealing ring 123, fixed
Position is enclosed 113, is interfixed the from-inner-to-outer of retainer plate 114, it is ensured that liner 120 and overcoat 110, overcoat 110 and external component
Connection is errorless.
With continued reference to Fig. 1 or Fig. 5, in one embodiment of the present invention, the radial width of liner 120 is along air inlet 150
Direction to gas outlet 160 gradually increases, i.e., in sectional view, the inwall of liner 120 is in outer expanding shape, to increase gas outlet 160
Air-out area.It is appreciated that according to the general principle of air amplifier 100, the flow velocity multiple that air amplifies is only empty with compression
The area of section S1 that gas is flowed at position is relevant with the ratio of overcoat 110 and the area of section S2 of the junction of liner 120, therefore,
Increase the area of section of gas outlet 160, can correspondingly increase air-out area.
In another preferred embodiment, overcoat 110 is provided with an annular boss 115, the convex annular near the part of air inlet 150
End of the platform 115 alternatively with air inlet 150 is connected, to form the ora terminalis of smoothly air inlet 150.The annular boss 115 can
For supporting liner 120, and coordinate with the gap of liner 120, to form previously described gap 140.As in the previous paragraph, S1 with
The area ratio of S2 is bigger, and air velocity is faster, and the boss can further reduce the section of overcoat 110 and the junction of liner 120
Area S2, so as to improve the effect of air amplification.
It should be noted that embodiments of the invention have a preferably implementation, and any type of not is made to the present invention
Limitation, any one skilled in the art changes or is modified to equivalent effective possibly also with the technology contents of the disclosure above
Embodiment, as long as without departing from the content of technical solution of the present invention, being made to above example according to technical spirit of the invention
Any modification or equivalent variations and modification, still fall within the range of technical solution of the present invention.
