A kind ofly go out the mist head
Technical field
The utility model relates to a kind of mist head that goes out, this kind goes out the mist head and is used for spray fan.
Background technology
Electric fan of the prior art generally all rotates blowing through the driven by motor flabellum, and when temperature was higher, the wind that blows out still was hot, does not have cool sense, even also can feel hotter.When having steam in the wind that fan blows out, will reach cool effect with directly contacting human body skin because of water evaporation.So, the appearance of spray fan has just been arranged, generally be provided with out the mist device in the fan cover body of spray fan; Mist goes out to the external world through this device; As everyone knows, the size of the amount of mist that spray fan goes out, and the size of fan air flow; Directly influence cooling-down effect, the size of fog-supplying amount receives the electric fan Influences on Wind Velocity again.But in the spray fan of the prior art to go out the mist apparatus structure complicated, it is not good to go out fog effect, so that causes the cooling-down effect of spray fan not good.
The utility model content
The utility model technical issues that need to address provide a kind of mist head that goes out, and this kind fog-spray nozzle is beneficial to out mist, and it is little influenced by the wind speed of fan, have improved the cooling efficient of spray fan.
The utility model can be taked following technical scheme:
A kind ofly go out the mist head, it is characterized in that: comprise housing, housing is made up of rounded bottom surface and sidewall, and sidewall is round the bottom surface, and the feather edge of sidewall and the edge of bottom surface border on, and bottom surface and sidewall are connected together, and perhaps bottom surface and sidewall are one-body molded; Said sidewall is provided with fog inlet.
The utility model is dealt with problems and can also further be taked following corrective measure:
Its inner face of said bottom surface is provided with fog-proof plate, is provided with the gap between fog-proof plate and fog inlet, is provided with the gap between fog-proof plate and sidewall.
Said fog-proof plate faces fog inlet, and its projected area at the fog inlet place is three minutes to 2/3rds of fog inlet area of section.
Its face towards fog outlet of said fog-proof plate is an arcwall face.
Its face towards fog outlet of said fog-proof plate is an arcwall face, the parallel axes of its axis of this arcwall face and said bottom surface.
Its wall of said sidewall is the side of truncated cone-shaped, and sidewall begins toward other end expansion radially outward gradually from that end of bordering on bottom edge.
The angle β scope of its incline of said side and bottom surface is 15~21 degree.
It is being provided with shutter with place, fog inlet corresponding edge said sidewall, and the corresponding edge of shutter one edge and sidewall borders on, and said shutter and sidewall are one-body molded, and perhaps said shutter and sidewall are independent separately, and shutter is connected with the sidewall detachable type.
Said shutter slopes inwardly.
Said shutter is an arc.
Technique scheme has such technique effect:
1, to go out mist head fog-supplying amount big for the utility model, do not receive the influence of fan wind speed, is beneficial to the cooling ability and the efficient that improve fan.
2, the utility model goes out the mist head and is provided with fog-proof plate, makes the mist that gets into out the mist head from fog inlet can separate two parts, and mist is come out from going out the mist head equably.
3, the utility model goes out its sidewall of mist head and becomes to have certain angle with the bottom surface, and the fog-supplying amount that this angle is beneficial to out the mist head does not receive the fast influence of fan wind.
4, the utility model goes out the mist head and is provided with shutter, and shutter is avoided producing the airflow influence mist from the wind that fan is produced by boasting and got into out the mist head, thereby helps stablizing fog-supplying amount.

The specific embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Embodiment: to shown in Figure 7, a kind of go out the mist head like Fig. 1, comprise housing; Housing is made up of rounded bottom surface 1 and sidewall 2, and sidewall 2 is round the bottom surface 1, and the edge of the feather edge of sidewall 2 and bottom surface 1 borders on; Bottom surface 1 is connected together with sidewall 2, and perhaps bottom surface 1 is one-body molded with sidewall 2; Said sidewall is provided with fog inlet 4.
The another improvement instance of the utility model is: said bottom surface 1 its inner face is provided with fog- proof plate 3, and 4 of fog-proof plate 3 and fog inlets are provided with the gap, and 2 of fog-proof plate 3 and sidewalls are provided with the gap.Fog-proof plate can rebound the mist that blocks return, and comes out from going out the mist head then, and helping the mist head, to go out mist even.
The another improvement instance of the utility model is: said fog-proof plate 3 faces fog inlet 4, and its projected area at fog inlet 4 places is three minutes to 2/3rds of fog inlet area of section.Fog-proof plate can block bounce-back from the mist that fog inlet gets into returns, and comes out from going out the mist head then, and the mist that does not block will move on, and receives the mist that rebounds out again after the stopping of sidewall then, and this structure helps the mist head, and to go out mist even.
The another improvement instance of the utility model is: said fog-proof plate 3 its faces towards fog outlet 4 are arcwall face.Arcwall face helps the mist that gets into from fog inlet is successfully disperseed, and using the mist head, to go out mist even.
The another improvement instance of the utility model is: said fog-proof plate 3 its faces towards fog outlet 4 are arcwall face, the parallel axes of its axis of this arcwall face and said bottom surface.
The another improvement instance of the utility model is: said sidewall 2 its walls are the side of truncated cone-shaped, and sidewall 2 begins toward other end expansion radially outward gradually from that end of bordering on bottom edge.The angle β scope of its incline of said side and bottom surface is 15~21 degree.The fog-supplying amount that this structure is used the mist head does not receive the fast influence of fan wind, can stop what fan blew out, lets mist successfully go out to the external world from going out the mist head.By design demand, the angle β scope of its incline of said side and bottom surface can be 15 degree, 18 degree, 21 degree, is 15~21 one of them value of degree for scope perhaps.
The another improvement instance of the utility model is: it is being provided with shutter 5 with place, fog inlet 4 corresponding edges said sidewall 2; The corresponding edge of shutter 5 one edge and sidewall 2 borders on; Said shutter 5 is one-body molded with sidewall 2; Perhaps said shutter 5 is independent separately with sidewall 2, and shutter 5 is connected with sidewall 2 detachable types.The mist that goes out that has the shutter plate can avoid providing the mist head from the blast that the wind that fan blows out forms impacts.Said shutter and sidewall are independent separately, help moulding separately, the convenient manufacturing.Detachable type connects, and can adopt screw to connect.
The another improvement instance of the utility model is: said shutter slopes inwardly.
The another improvement instance of the utility model is: said shutter is an arc.
As shown in Figure 7, go out the mist head when using, be located at the fan housing middle part of fan.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
