Abstract
The utility model relates to a torsion-free omnibearing uniform wind ceiling fan, which is a ceiling fan supplying wind for large area. On the basis of an existing plane ceiling fan with a single fan, an air pressing fan is added. The air pressing fan is composed of 20 to 10 blades tilting upwards with an angle of 10 to 40 DEG. Blade tips are fixed by a circular ring. When running, the torsion-free omnibearing uniform wind ceiling fan can supply high-speed wind towards the downwards tilting direction. The utility model has the advantages of small volume of the air pressing fan, no torque, easy installation, damage prevention for people because of the circular ring of the blade tips, and high strength of the air pressing fan.
Description
The utility model is a kind of pectinid device, can be to the large size air feed, and volume own is less, a kind of ceiling fan of no moment of torsion.
Present known ceiling fan has only a fan, has taken very big head room, and wind-force only acts under it, and wind-force is just very weak slightly at a distance.The moment of fan when rotating in order to resist needs to be fixed on the ceiling board with iron staff, and very high to the ceiling board requirement of strength, wooden ceiling board just can't be installed.The fan of high speed rotating is also easily chopped wound the people.
The purpose of this utility model provides a kind of ceiling fan, and not only volume is little for it, can blow to large area region, and not have moment of torsion, can be installed on the various ceiling boards, be hung on the rope also passable, and safety relatively.
The purpose of this utility model is achieved in that ceiling fan is enclosed within the fan of doing the opposite direction rotation on the axle by two groups and forms.Two fans are air-supply downwards all, second layer rotation speed of the fan is faster than first layer, rotating ratio can be controlled by gear controller, and the air that the first layer fan blows out further quickens through second layer fan, the wind speed that the speed of the wind that obtains like this can produce greater than the identical individual layer fan of area.Simultaneously, adopt the fan quality and the rotating speed of two counter-rotatings that certain relation is arranged, upper strata fan quality is bigger than lower floor fan, the rotating ratio second layer is slow, and rotating speed is controlled by gear controller, and the torque of generation equates, direction is opposite, cancels out each other, so lower to the requirement of strength of fixed block.But fan height free adjustment, and can not produce dancing.Blade is rolled over 10-40 degree angle obliquely upward from 1/5-2/3, the oblique below of the wind direction that the outer end blade is blown, under the wind direction that inner place blade blows, thus the active area of expansion fan.Each fan is made up of 2-10 sheet blade.These blades are linked up with a safe annulus at blade tip, can improve the intensity of whole fan on the one hand, can prevent injury on the other hand to human body, according to test, the fan the easiest people's of chopping wound position is a blade tip, and article from the bottom surface near the time can be flicked, and novel fan has been taked the design of multi-disc blade, article are easier to be flicked, and further reduces this danger.
Owing to adopt such scheme, can make than the fan of small size and just can give the air-supply of larger area room, and wind-force be powerful.Be well suited for places such as hotel family of school.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the plan view of the utility model ceiling fan lower floor fan.
Fig. 2 is that the A-A of Fig. 1 is to view.
1. hooks, 2. hanging scrolls, 3. safe annulus 4. upper strata blades 5. blade knuckles one 6. motor one 7. lower floor's blades 8. motor 2 9. blade corners 2 10. are from snap close among the figure
Among Fig. 1, hook 1 has-from snap close 10, can make things convenient for securely to hang on the roof.Upper strata fan and lower floor's fan spacing are very little, and motor-the 6th is rotated counterclockwise, blade 4 axis are vertical with hanging scroll, and the oar face becomes 10-400 degree angle with horizontal plane.Blade is rolled over the 10-40 degree obliquely upward from 5.This knuckle can be adjusted, and makes with maximum windward side to blow to oblique below.Motor 28 is that the blade that changes clockwise becomes 130-160 degree angle with horizontal plane.
Claims (4)
1, a kind of ceiling fan is characterized in that: the coaxial fan of two groups of direction of rotation is arranged, and every fan blade all has 10-40 degree knuckle obliquely upward, and blade tip is with safety cycle.
2, according to the described ceiling fan of claim 1, its feature: fan blade number can be made of the 2-10 sheet, and blade gives a discount from 1/5-2/3, and blade-span axis is perpendicular to hanging scroll, and back segment is from discounting knuckle 10-40 degree obliquely upward.
3, according to the described ceiling fan of claim 1, its feature: fan can adopt the engineering plastics once-through, also can be divided into blade, annulus, motor case and make respectively, and riveted joint is got up again.
4, according to the described ceiling fan of claim 1, its feature: the fan wing tip has the fixing safe annulus of blade tip.
