Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in attached drawing 1, attached drawing 2, attached drawing 3, a kind of high light transmission of the present embodiment stablizes mist screen generating device, including is set to
System layer stream 2 and spraying system 3 on bracket 1.
System layer stream 2 includes the blower fan group 22 on 1 top of bracket, and blower fan group 22 is in array distribution, blower fan group in the horizontal plane
The air filtration slot 23 of 22 two pieces of lower section face horizontal alignments, it is 8mm-12mm's that air filtration slot 23, which is equipped with array distribution side length,
Square hollow hole 25, the air stream that blower fan group 22 generates form lamina air flow 26 after hollow hole 25, it is preferred that hollow hole
25 side length is 10mm, not only can reduce due to mesh is too small and noise excessive problem when bring air-flow is discharged, but also can be more
Mend due to hollow hole 25 is excessive and problem that bring mist screen picture is not fine and smooth, blower fan group 22 are connect with I 21 electric appliance of governor, tune
The revolving speed of blower is saved, the fog channel 24 that the gap formation width between air filtration slot 23 is 1-2mm.
Spraying system 3 includes the water tank 31 set on 1 lower part of bracket, the atomizer 32 being equipped in water tank 31,31 side wall of water tank
Spray outlet is opened up, spray outlet connect 35 with fog output tube by pipeline 34, and fog output tube 35 opens up and fog channel pair along axial direction
The fog outlet 36 connect.Spray outlet opens up corresponding air inlet to side box wall, and the wind that wind direction is directed toward spray outlet is arranged in air inlet
Machine II 33, blower II 33 are connect with II 37 electric appliance of governor.36 width of fog outlet is corresponding with 24 width of fog channel, fog outlet 36
It is abutted with the matching of fog channel 24, after atomizer 32 produces mist, blower II 33 blows into water mist after pipeline 34 to be entered through fog outlet 36
Fog channel 24, water mist form mist screen 39 behind fog channel 24, and the width in fog channel 24 is smaller, and water mist flow velocity is faster,
Then mist screen 39 is more stable, and 39 two sides of mist screen are that air passes through the lamina air flow 26 formed after hollow hole 26, passes through lamina air flow 26
Mist screen 39 can be protected.
31 upper end of water tank is drawable chamber door 38, the pull knot with existing pull cabinet and the Key board drawer of computer desk
Structure is the same, and water tank 31 is transparent material, it is observed that chamber door 38 is pulled open when water is inadequate in water tank 31, directly toward water tank
In 31 plus water, 1 lower end of bracket is provided with idler wheel 4, and device easy to remove is used for multiple places.
As shown in Fig. 4 according to experimental data, with the reduction of mist screen thickness, transmissivity of the laser in mist screen gradually increases
Greatly, work as T=1mm, when laser normal incidence, transmissivity highest has reached 94.067%, as shown in Fig. 5, with mist screen thickness
Reduce, reflectivity of the laser in mist screen gradually decrease, and works as T=1mm, and when laser normal incidence, reflectivity is minimum, only
0.336%, it is preferred that the width in fog channel 24 is 1mm, and the width in fog channel 24 is small, and water mist flow velocity is fast, and mist screen 39 is steady
It is fixed, and light transmittance is high, reflectivity is low, and mist screen 39 is imaged apparent.
According to Reynolds formulaIt is found that atmospheric density ρ, air viscosity μ are fixed value, when flow diameter is fixed
When 10mm, air velocity V is smaller, and Reynolds number R is smaller, and as R < 1000, air draught is laminar flow, could in one direction
Uniform motion plays a protective role to intermediate mist screen.Lamina air flow 26 positioned at 39 two sides of mist screen protects mist screen 39, empty
The flow velocity of gas-bearing formation stream 26 is smaller, and the stability of mist screen is better, reduces sky by the revolving speed that governor I 21 reduces blower fan group 22
The flow velocity of gas-bearing formation stream 26, increases and protects to mist screen 39, and mist screen 39 is more stable.Meanwhile blower II 33 is increased by governor II 37
Revolving speed and accelerate the flow velocity of water mist, mist screen 39 is more stable, and by setting 24 width of fog channel as 1mm, the stream of water mist
Speed is accelerated, and mist screen 39 is more stable, and the mist screen formed with a thickness of 1mm, light transmittance are high, and reflecting rate is low, mist screen 39 be imaged it is apparent,
It is firm.
It is encountered in debugging or use process before stablizing mist screen generating device using a kind of high light transmission of the present patent application
When influencing unstable, governor I 21 and governor II 37 stream of the flow velocity to lamina air flow 26 and water mist respectively can be passed through
Speed is adjusted, so that the imaging of mist screen is more stable.
Above embodiments, only preferred embodiments of the invention, be not to limit the scope of the present invention, therefore it is all according to the present invention
The equivalent change or modification that structure, feature and principle described in claim is done should be included in the invention patent Shen
It please be in range.
