Abstract

Disclosed is a multi-head electric fan. A vertical shaft capable of being driven to rotate by a motor at the bottom is designed, a large bevel gear is mounted at the top end of the vertical shaft, a plurality of fan heads are uniformly arranged at the top end of the vertical shaft, small bevel gears are mounted at the tail ends of horizontal shafts of the fan heads and are meshed with the large bevel gear at the top end of the vertical shaft, fan blades of the fan heads are mounted at the front ends of the horizontal shafts, safety hoods are arranged outside the corresponding fan blades, bearings are mounted on the vertical shaft and the horizontal shafts, and the safety hoods and the bearings are fixed onto a box. When the multi-head electric fan is used, the motor is powered on and drives the vertical shaft to rotate, the vertical shaft simultaneously transfers rotation to the horizontal shafts of the fan heads through the large bevel gear and the small bevel gears, the horizontal shafts drive the fan blades of the fan head to simultaneously rotate, so that peripheral continuous blowing functions are achieved, and the bearings can keep relative positions of the vertical shaft and the horizontal shafts fixed and maintain transmission stability.

Description

The bull electric fan
Technical field
The utility model relates to the electric fan technical field, more particularly, relates to a kind of bull electric fan.
Background technique
At present, the electric fan on the market rotates to dry by the motor driving rotor mostly.But this electric fan has only a fan head mostly, can only directed dry, if use the function of shaking the head simultaneously, the wind that then blows to a certain direction is discontinuous again, and this electric fan does not just satisfy people to the demand of blowing in some cases.
Summary of the invention
For overcome existing electric fan can only directed blowing or to around the discontinuous deficiency of drying, the utility model provides a kind of bull electric fan, this electric fan can realize simultaneously to around the function of drying continuously.
The technical scheme in the invention for solving the technical problem is: design a vertical shaft that can utilize the motor driving rotation in the bottom, cone gear is installed on the vertical shaft top, a plurality of fan heads are evenly arranged in the vertical shaft top, fan head transverse axis terminal installation cone pinion also makes it to be meshed with the cone gear on vertical shaft top, the flabellum of fan head is installed in the front end of transverse axis, flabellum has safety enclosure outward, bearing all is installed on vertical shaft and the transverse axis, and safety enclosure and bearing all are fixed on the casing.During use, electrical power, the rotation of driving vertical shaft, vertical shaft will rotate the transverse axis that passes to fan head simultaneously by cone gear and cone pinion, realize the while to the function of drying continuously all around thereby the flabellum of transverse axis drive fan head rotates simultaneously, bearing then can keep the relative position of vertical shaft and transverse axis to fix and keep the stable of transmission.
The beneficial effects of the utility model are, can be simultaneously to around blowing continuously, simple in structure, practicality.
Description of drawings
Below in conjunction with accompanying drawing (be example with four fan heads) and embodiment the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view after the utility model removes Box Cover.
1. safety enclosures among the figure, 2. flabellum, 3. transverse axis, 4. bearing, 5. cone pinion, 6. cone gear, 7. casing, 8. vertical shaft, 9. motor.
Embodiment
In the drawings, design a vertical shaft (8) that can utilize motor (9) to drive rotation in the bottom, cone gear (6) is installed on vertical shaft (8) top, four fan heads are evenly arranged in vertical shaft (8) top, fan head transverse axis (3) terminal installation cone pinion (5) also makes it to be meshed with the cone gear (6) on vertical shaft (8) top, the flabellum of fan head (2) is installed in the front end of transverse axis (3), safety enclosure (1) is arranged outside the flabellum (2), on vertical shaft (8) and the transverse axis (3) bearing (4) is installed all, safety enclosure (1) and bearing (4) all are fixed on the casing (7).During use, motor (9) energising, drive vertical shaft (8) rotation, vertical shaft (8) will rotate the transverse axis (3) that passes to four fan heads simultaneously by cone gear (6) and cone pinion (5), thereby transverse axis (3) drives the flabellum (2) of four fan heads rotates simultaneously and realize the while to the function of drying continuously all around, and bearing (4) then can keep vertical shaft (8) and the relative position of transverse axis (3) to fix and keep stablizing of transmission.

Claims (3)

1. bull electric fan is characterized in that: design a vertical shaft, cone gear is installed on the vertical shaft top, and the terminal cone pinion of installing of fan head transverse axis also makes it to be meshed with the cone gear on vertical shaft top.
2. bull electric fan according to claim 1 is characterized in that: vertical shaft can utilize the motor driving rotation in the bottom, and fan head is evenly arranged in the vertical shaft top.
3. bull electric fan according to claim 1, it is characterized in that: the flabellum of fan head is installed in the front end of transverse axis, and flabellum has safety enclosure outward, and bearing all is installed on vertical shaft and the transverse axis, and safety enclosure and bearing all are fixed on the casing.
