Motor described in the utility model is fixed in electric machine support, and electric machine support is fixed on the fan front and rear casing, and the rotating shaft of motor is connected with the wind drum.
Wind described in the utility model drum lower end is connected with machine shaft, upper end and being fixed on the fan back cover bearing means.
Wind deflector described in the utility model is separately fixed on the fan front and rear casing, and wherein wind deflector is the concave circular arc type, and the shape of second wind deflector and first wind deflector is the dome arc shape.
Be fixed with the protective net grid on the exhaust outlet described in the utility model.
Direct box internal fixation described in the utility model has circuit board, control knob, Direct box bottom cover members.
The utility model compared with prior art, because electric fan is provided with two exhaust outlets that are mutually 70 degree～100 degree angles, have that blowing range is big, the air-out simultaneously of the exhaust outlet of two different amount, also can an advantage such as exhaust outlet air-out, energy consumption is low simultaneously, noise is little, Safety performance is high, be convenient to collection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As depicted in figs. 1 and 2, electric fan of the present utility model is made up of base disk 1, support vertical rod 2, tuner 3, synchronous machine 4, synchronous rotating disk 5, electric machine support 6, motor 7, fan back cover 8, wind deflector 9, second wind deflector 10, net grid 11, wind drum 12, first wind deflector 13, fan fore shell 14, the second net grid 15, bearing means 16, Direct box bottom 17, circuit board 18, control knob 19, Direct box 20 etc.Base disk 1 is to fall to putting ground and play the balance electric fan.Support vertical rod 2 and be fixed between base disk 1 and the tuner 3, play a part to support and regulate the electric fan height.Tuner 3 is fixed on and supports in the vertical rod 2, also fixing synchronous machine 4, and be to maintain static.Synchronous machine 4 is connected with synchronous rotating disk 5, forms rotating mechanism.Rotating disk 5 is fixed on the electric fan front and rear casing 14,8 synchronously, and when synchronous machine 4 runnings, rotating disk 5 drives electric fan top and does the yaw running synchronously.Electric machine support 6 is fixed on the fan front and rear casing 14,8, mainly has been the effect of fixed electrical machinery 7.Motor 7 rotating shafts are connected with wind drum 12; The lower end of wind drum 12 is connected with the rotating shaft of motor 7, and the upper end is fixed on fan back cover 8 bearing meanss 16.Drive wind drum 12 at motor 7 and run up down, produce air draught.
Three wind deflectors 9,10,13 are separately fixed on the fan front and rear casing 14,8, wherein wind deflector 9 is concave circular arc shape (a wind-guiding function), the shape of second wind deflector 10 and first wind deflector 13 is dome arc shape (functions of keeping out the wind), and dome camber shape is shorter, concave circular arc type shape long (wherein having the certain proportion relation).The position of three wind deflectors changes because of the position change of intake grill on motor (7) drive manner and the fan front and rear casing (14,8) and exhaust outlet.
Net grid 11,15 of the present utility model are fixed on the exhaust outlet of fan front and rear casing 14,8, play the protection safety effect.Direct box 20 internal fixation parts such as circuit board 18, control knob 19, Direct box bottom 17, the power supply of major control electric fan, air quantity, regularly, function such as yaw, negative ion.
Electric fan of the present utility model because the exhaust outlet on the front and rear casing 14,8 of fan becomes 70 degree～100 degree angles, until concrete one-tenth 90 degree angles (exhaust outlet can on the left side or the right of another exhaust outlet).Motor 7 drives the wind drums 12 generation air draught that runs up, and therefore three wind deflectors 9,10,13 can produce the air-out that is in an angle of 90 degrees direction with two exhaust outlets of air-flow guiding.Under synchronous machine 4 working orders, drive synchronous rotating disk 5 and be fixed on synchronous rotating disk 5 and fan front and rear casing 14, motor 7 on 8, wind drum 12, three wind deflectors 9,10,13 parts such as grade rotate, the wind radiation that the exhaust outlet of fan front and rear casing is sent reaches the above scopes in 180 degree angles, the scope that this scope is traditional head and shoulders above.
Electric fan of the present utility model can be according to user's needs, and the external form of fan and exhaust outlet is made various variation.One of exhaust outlet can be in the left side or the right of another exhaust outlet, front or back etc.Can be used as styles such as vertical, desk-top, hanging as electric fan.In addition, also can form different series product according to the difference of electric fan size.
