Abstract
The utility model discloses an air outlet ring of a turbo type bladeless fan, which comprises an outer ring surface and an inner ring surface. One ends of the outer ring surface and the inner ring surface are sealed up in combined mode, and a gap is disposed between the other ends of the inner ring surface and the outer ring surface and forms an annular air outlet. A preferential width of the annular air outlet is 0.5-1.5 mm, an air outlet passage is formed between the outer ring surface and the inner ring surface, and the lower end of the outer ring surface is opened to form an air inlet passage used for air inlet from a base. The turbo type fan is arranged inside the base, and therefore, no blades are arranged on the outer surface, the air outlet ring is safe and reliable, smooth in all the outer surfaces, and easy to clean.
Description
Technical field
The utility model relates to a kind of fan and goes out solar or lunar halo.
Background technique
Mostly conventional fan is that blade generation that driven by motor one circle rotate around electrical axis is distinguished and admirable and blows forward; Exist outside blade space is exposed to, to the people particularly child exist potential safety hazard, and the motor blade is exposed entirely; Laying dust also is difficult for behind the laying dust cleaning easily.
Summary of the invention
The utility model problem to be solved provides a kind of turbo type safe, that be prone to clean not to be had blade fan and goes out solar or lunar halo.
The technological scheme that the utility model adopted is: turbo type does not have blade fan and goes out solar or lunar halo and comprise outer ring surface and inner ring surface; Said outer ring surface and inner ring surface one end combine sealing; The other end is provided with a slit-shaped between the two and circularizes exhaust outlet; Said annular exhaust outlet preferable width is 0.5-1.5mm, and the space forms the air-out passage between outer ring surface and the inner ring surface, and said outer ring surface lower ending opening forms air intake passage in order to from the base air intake.
In the such scheme, said inner ring surface is and outwards is angle from annular exhaust outlet is 12 °～16 ° inclined-plane conical ring shape, and said bevel angle is preferably 14 °.
In the such scheme, said inner ring surface is from annular exhaust outlet and outwards is cambered surface conical ring shape.
The beneficial effect of the utility model is: the utility model turbo type does not have blade fan and goes out solar or lunar halo and comprise outer ring surface and inner ring surface, and said outer ring surface and inner ring surface one end combine sealing, and the other end is provided with a slit-shaped between the two and circularizes exhaust outlet; The space forms the air-out passage between outer ring surface and the inner ring surface, and said outer ring surface lower ending opening forms air intake passage in order to from the base air intake, and turbofan is located in the base; Outer surface on-bladed like this; Safe and reliable, and appearance is smooth surface, cleaning easily.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the surface structure schematic representation of the utility model embodiment one;
Fig. 2 is the sectional structure schematic representation of the utility model embodiment one;
Fig. 3 is the broken section structural representation of the utility model embodiment two.
Embodiment
Like Fig. 1, shown in Figure 2; Turbo type does not have blade fan and goes out solar or lunar halo 2 and link to each other with base 1, is provided with turbofan in the base 1, and turbo type does not have blade fan and goes out solar or lunar halo 2 and comprise outer ring surface 21 and inner ring surface 22; Inner ring surface is and outwards is angle from annular exhaust outlet is 14 ° inclined-plane conical ring shape; Outer ring surface 21 combines sealing with inner ring surface 22 1 ends, and the other end is provided with a slit-shaped between the two and circularizes exhaust outlet 23, and annular exhaust outlet 23 width are 1mm; The space forms air-out passage 24 between outer ring surface 21 and the inner ring surface 22, and outer ring surface 21 lower ending openings form air intake passage 25 in order to from base 1 air intake.
Fig. 3 is the broken section structural representation of the utility model embodiment two, and difference is that inner ring surface is from annular exhaust outlet and outwards is cambered surface conical ring shape.
Claims (5)
1. a turbo type does not have blade fan and goes out solar or lunar halo; It is characterized in that: said turbo type does not have blade fan and goes out solar or lunar halo and comprise outer ring surface and inner ring surface; Said outer ring surface and inner ring surface one end combine sealing; The other end is provided with a slit-shaped between the two and circularizes exhaust outlet, and the space forms the air-out passage between outer ring surface and the inner ring surface, and said outer ring surface lower ending opening forms air intake passage in order to from the base air intake.
2. turbo type does not have blade fan and goes out solar or lunar halo according to claim 1, and it is characterized in that: said annular exhaust outlet width is 0.5-1.5mm.
