Abstract
The utility model relates to an electric fan with double blades, which is composed of a fixing plate, a stator, an inner rotor, an outer rotor, an inner blade, and an outer blade. The stator is arranged on the fixing plate. The inner wall and the outer wall of the stator are provided with a plurality of grooves which are provided with coils. The inner rotor is penetrated through the stator, and the outer rotor is arranged on the outer ring of the stator. After energization, the inner rotor and the outer rotor can simultaneously rotate, and the rotation directions of the inner rotor and the outer rotor are opposite. The inner rotor and the outer rotor are provided with the inner blade and the outer blade, wherein, the outer blade is provided with a wind direction adjustable mechanism. The utility model combines the advantages of a floor type fan or a desk fan, and a ceiling fan, and has the advantages of soft wind power, larger range of wind directions, and electricity saving.
Description
The utility model belongs to the electric fan field.
At present, the kind of electric fan is a lot, roughly is divided into two classes: a class is floor model or bracker fan, and the fan blade that this class fan adopts is less, the wind direction narrow range.Another kind of is ceiling fan, and the fan blade of employing is bigger, though the wind direction wide ranges, but must be suspended on the roof, be subjected to certain limitation during use, more than two class electric fans all be with fan blade of a driven by motor, a wind direction rotates, and not only wind-force is hard but also electric power is not utilized fully.
The purpose of this utility model provides motor of a kind of usefulness can drive two fan blades, and the energy-conservation electric fan of the two-way rotation of energy, and wherein external wind wheel can tuning wind direction.Both can also can use with it as floor model or bracker fan as ceiling fan.
The technical solution of the utility model realizes as follows: a kind of pair of fan blade electric fan, it is made up of fixed plate, stator, internal rotor, external rotor, interior fan blade and external wind wheel.Stator is housed on fixed plate, and stator is made with silicon steel,, be provided with a plurality of flutings around the outer wall, is provided with coil in the fluting within it.Internal rotor is through in the stator, by positioning bearing it is bearing on the fixed plate.The right-hand member of internal rotor and the left-end point of stator are provided with bearing.External rotor inwall employing drive fit is contained in the bearing outer ring on internal rotor and the stator.The left-end point of external rotor outer wall is provided with smooth arc surface, and arc surface is provided with a circle ball and a ball bowl, and the ball bowl is fixed on the fixed plate with screw.The external rotor wall is provided with straight fixing hinge identical with the blade number of external wind wheel and tiltedly fixing hinge, and straight fixing hinge is connected with the blade bottom of external wind wheel, and tiltedly fixing hinge is connected with the vacuum side of blade of external wind wheel, but the joint is provided with the turnbuckle of roll adjustment.The right top of internal rotor is equipped with interior fan blade.
The utility model compared with prior art integrates floor model or bracker fan and ceiling fan, and the switched in opposite of two fan blades, makes wind-force soft.Have simple in structurely, power-saving, the characteristics that the wind direction scope is big can satisfy various occasions and use.
Fig. 1 is the utility model structural representation;
Represented sequence number on the figure in Fig. 1: (1) is interior fan blade; (2) be straight fixing hinge; (3) be external wind wheel; (4) be turnbuckle; (5) be tiltedly fixing hinge; (6) be coil; (7) be fixed plate; (8) be stator; (9) be positioning bearing; (10) be internal rotor; (11) be bearing; (12) be external rotor; (13) be the ball bowl; (14) be arc surface; (15) be ball.
