Abstract

The utility model discloses an electric fan. The utility model is characterized in that an output shaft of a motor is fixedly connected with a transmission shaft fixedly connected with a supporting seat provided with three miniature motors, wherein, each output shaft of which is respectively provided with a blade. As the utility model adopts three fan motors to combine one electric fan machine core, an electric fan machine head composed of three motors and three blades is formed, and the electric fan machine head is made to rotate through one motor; accordingly, the electric fan can rotate within 360 DEG, and the three blades having different angles can produce a stereo wind effect.

Description

A kind of electric fan

The utility model relates to the technical field of electric fan, the electric fan that specifically a kind of energy 360 degree rotate.

Electric fan in the market comprises ceiling fan, desk fan, stand fan or box fan etc., design mostly in the conventional mode, promptly a motor adds fan blade, the rotating speed of regulating fan by control key to be regulating the large, medium and small variation of wind-force, and can rotate in the scopes of 180 degree and shake the head.

The purpose of this utility model is to provide a kind of improved electric fan, and it can rotate in the scope of 360 degree.

The technical solution of the utility model is achieved in that a kind of electric fan, it mainly comprises base, base-mounted column, be contained in lifting bar and control key in the column, be contained in the motor on the lifting bar, it is characterized in that: the output shaft of motor is fixedlyed connected with a transmission shaft, and this transmission shaft is fixedlyed connected with supporting base, on supporting base, be provided with three micromachines, fan blade all is housed on the output shaft of each micromachine.

The utility model is owing to adopted three fan motors to be combined into an electric fan movement, and fan blade is installed separately on the motor output shaft of three different amount, so just formed by three motor and three electric fan heads that blade is formed, again in addition by a motor, this electric fan head is rotated, this sample electric fan not only can rotate in the scope of 360 degree, and the fan blade of three different amount can produce the effect of three-dimensional wind sense.

Fig. 3 is a schematic representation of removing three blades and supporting base case among Fig. 2

Fig. 4 removes the electric fan head schematic representation that three blades are formed among Fig. 3

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises base 1, be contained in the column 5 on the base 1, be contained in lifting bar 25 and control key 6 in the column 5, be contained in the motor 24 on the lifting bar 25, this lifting bar is sent out 5 pillars as support motor and electric fan movement, press control key 6 and just can in certain scope, regulate the height of lifting bar, it is different from prior art and is: the output shaft 27 of motor 24 is fixedlyed connected with a transmission shaft 22, this transmission shaft 22 is fixedlyed connected with supporting base 13, on supporting base 13, be provided with three micromachines 20, on the output shaft 28 of each micromachine 20 fan blade 15 be housed all; Three micromachines 20 that are contained in an embodiment on the supporting base 13 are evenly distributed; angle between two micromachines is 120 degree; output shaft 27 places at motor 24 adorn lateral pin; bore an aperture in the underpart of transmission shaft 22; fixedly connected with lateral pin at output shaft 27 places of motor 24; the lower end of transmission shaft 22 is approximately square; one rotation protecting sheet 23 is sleeved on the lower end of transmission shaft 22; the upper end of transmission shaft 22 is approximate rounded; one bearing 21 is contained in the upper end of transmission shaft 22; on bearing 21, install a supporting base 13; case 14 is housed on supporting base 13; the effect of the rotation protecting sheet of wherein setting up 25 is the rotations by transmission shaft 22; the rotation of driven rotary protecting sheet 25; make supporting base 13 when doing 360 degree rotations; lead can not put on the spot; in order to increase the function of electric fan; on lifting bar 25, also establish an outer cover 26; establish a lampshade 8 at lifting bar 25 places; in lampshade 8, adorn a lamp 7; during concrete the assembling; after loading onto fan blade 15 on the output shaft 28 of each micromachine 20, adopt nut 16 fixing again; present embodiment also is equipped with touch-button 2 on base 1; remote controller 3 and the gas outlet 4 that negative ion air-cleaner is housed; these are prior art; be not described specifically at this; guard 9 and last guard 10 down also are housed at lampshade 8 places of supporting base 13 peripheries that three micromachines 20 and fan blade 15 are housed; 10 places also establish one handle 11 at last guard; so that lift electric fan; lower end at handle 11 also can be established a box body 12; this box body is used to deposit the air aromatic sheet of solid; during use as opening the anion fine-purification device and giving the heating of aromatic sheet; but the air in this electric fan purifying chamber; give out a burst of delicate fragrance; the lampshade of setting up disposes corresponding drive Compact Fluorescent Lamp has more more increased the convenience of using; in addition by the running of the fan blade on micromachine of touch-button may command; fan blade on other two micromachines shuts down; or start two fan blades runnings on the micromachine; stop a fan blade running on the micromachine; or the fan blade on three micromachines turns round simultaneously, can reach good effect as required.
