Summary of the invention
The utility model aims to provide a kind of 360 degree rotating electric fans, this 360 degree rotating electric fan novel structure, simple, and cost is lower.
360 degree rotating electric fans described in the utility model, comprise motor, coupling, main shaft, sun gear, cone gear, fan rachis, flabellum, Worm and Worm Gear Driving, planetary pinion, planet carrier and fixed base, described motor is connected with main shaft by coupling, drive main spindle is rotated, then by Bevel Gear Drive by transmission of power to fan rachis, flabellum is fixedly installed in fan leaf the tip of the axis; Described fan rachis is also worm shaft simultaneously, and the power that transmits fan rachis by Worm and Worm Gear Driving is to planetary pinion; Described sun gear and planetary pinion engagement, during work, sun gear does not turn, and in the time of planetary pinion rotation, revolves round the sun again around sun gear.
The beneficial effect of this scheme is because adopted the planetary gear transmission mechanism of innovation, and that has avoided that in prior art, 360 degree rotating electric fans adopt passes through brush to the labyrinth mode of motor power supply, thereby has optimized structure, reduced cost.In addition compare with the electric fan of common small angle oscillation, the space of the fan air-supply of this programme increases, and correspondingly takes up space littlely, is particularly useful for the more concentrated public arena of personnel.
Described Worm and Worm Gear Driving comprises worm shaft, worm gear and worm-wheel shaft, and described worm shaft and fan rachis are the same axis, and described worm-wheel shaft and planet pin are the same axises.
The axis of described planet carrier overlaps with main shaft, is connected respectively with fan rachis with worm-wheel shaft.
On the other end of described fan rachis, also flabellum can be installed.
Described flabellum can be installed or oppositely install by forward.Forward is installed for air-supply, oppositely installs for exhausting.
Described main the tip of the axis is also provided with flabellum, and the flabellum on this flabellum and fan rachis is reverse installation.
The beneficial effect of technique scheme is to have increased new function for 360 degree rotating electric fans.The one, Double-head fan can be blown from both direction electric fan simultaneously, plays better air-supply effect.Another kind of application is by reverse installation flabellum, fan is played and take out wind action, and it is connected with air draft pipeline, can play good exhausting effect; At this moment main the tip of the axis also can be installed flabellum, and this flabellum is oppositely installed, and among air draft pipeline, plays better exhausting effect.
The working principle of this technological scheme is: motor passes to cone gear by power by main shaft, and by Bevel Gear Drive, the also transferring power of slowing down, to fan rachis, rotates the flabellum on fan rachis.Meanwhile, by Worm and Worm Gear Driving by transmission of power to planetary pinion.Because sun gear is fixed, so when planetary pinion rotation, revolve round the sun around sun gear again.
The utility model is by adopting unique planetary gear transmission mechanism as fan structure, can play in comparatively simple mode the technique effect of 360 degree space air-supplies, overcome the flimsy defect of prior art complex structure, applicable while being especially applicable to many people polymerization, in the middle of one desk fan is placed in, just can guarantee the proprietary needs of surrounding space.
