Abstract
The utility model relates to a double-head automatic rotation electric fan. The double-head automatic rotation electric fan comprises a vertical shaft (6), an articulated seat (5), a motor (1), impellers (3) and a horizontal shaft (2); the vertical shaft (6) is connected with the articulated seat (5) in the vertical direction; the articulated seat (5) is fixedly connected with the two impellers (3); the impellers (3) are in shaft connection with the motor (1); and the vertical shaft (6) and the horizontal shaft (2) are arranged on an axis in a cross manner. The double-head impellers supported by the vertical shaft further are adopted for further generating a 360-degree air current movement atmosphere; as a torsion forming headshaking comes from a counteracting force of air currents when the impellers rotate; as the counteracting force is soft, is persistent and appropriate and the rotating speed can be controlled, the abrasion can be obviously reduced, and the service life of the motor is prolonged; and the double-head automatic rotation electric fan has more prominent energy saving and comfort effect.
Description
Technical field
The utility model belongs to civil electric appliance technology or device, especially a kind of double end spin electric fan.
Background technique
Existing civilian electric fan product is distinguished from relative position between motor shaft and fan fixer Support Level, mainly divides two types; One type is fixed, i.e. motor fixed installation is outside impeller sways; Do not move between impeller self and fan fixer, and another kind of be that the motor shaft that is connected with impeller and corresponding connection set thereof are along the swing of fan fixer vertical support direction covering of the fan, promptly so-called oscillating fan; This shaking with motor special drives; Rotation angle is not more than 180 °, and in addition, improved technology has the pair in a kind of wind blows impeller installing frame can utilize wheel rotation the time to turnstile slowly to rotate; And influence airspeed and direction, form the effect of flow-disturbing with natural imitation wind.
The analysis of summarizing; Even the structure oscillating fan of the electric fan in the known technology also only is that the head-shaking device through electric fan carries out the regional area pectinid, can not be to the arbitrary independent pectinid of arbitrary region; Can not 360 degree pectinids simultaneously, it is relevant that to improve technology less.
Summary of the invention
The purpose of the utility model provides a kind of double end spin electric fan.
The goal of the invention measure that realizes the utility model is: by vertical shaft, and hinged seat, motor, impeller constitutes, and vertical shaft connects hinged seat in vertical direction, and hinged seat is fixedly connected two impellers, and impeller is connected with motor shaft, and vertical shaft and transverse axis intersect installation on axis.
The advantage of the utility model is, adopts the double end impeller that supports with vertical shaft, further generates the atmosphere of 360 ° of air motions; Because the reaction force of air-flow when forming the moment of torsion shake the head from wheel rotation; This active force is gentle slow to be continued suitablely, and the speed of rotating can control, and therefore significantly alleviates wearing and tearing; Prolonged electrical machinery life, energy-conservation and comfortable effect is more outstanding.
Description of drawings
Fig. 1 is the structural representation of the utility model
Reference character comprises: motor 1, transverse axis 2, impeller 3, wheel protect 4, hinged seat 5, vertical shaft 6, base 7.
Embodiment
Below in conjunction with specific embodiment, describe:
The utility model is by vertical shaft 6, hinged seat 5, and motor 1, impeller 3 constitutes, and vertical shaft 6 connects hinged seat 5 in vertical direction, and hinged seat 5 is fixedly connected two impellers 3, and impeller 3 is connected with 1 in motor, and vertical shaft 6 and transverse axis 2 intersect installation on axis.
Two impellers 3 are installed in the both sides of vertical shaft 6 for a point symmetry with hinged seat 5.
Two impeller 3 public motors 1, this motor 1 is installed in vertical shaft 6 tops, and connects two impellers 3 at two ends through shaft coupling or speed reducer.Further, be connected through transverse axis 2 in 3 in motor 1 and impeller.
Perhaps, two impellers 3 respectively connect a motor 1, and this motor 1 is installed on transverse axis 2 outer ends.
Connect with transverse axis 2 in the middle of two impellers 3.
In more than selecting, two sections transverse axis 2 coaxial lines in vertical shaft 6 both sides, or along the installation of staggering of vertical shaft 6 axial directions.
In the utility model; Wheel protects 4 the raising Safety performance is installed; Simultaneously, two impellers 3 at two ends rotate back wind-force can produce the moment of torsion around vertical shaft 6, promotes hinged seat 5 and 6 on vertical shaft and relatively rotates; The impeller 3 that promptly forms both sides rotates around vertical shaft 6 naturally, further generates the atmosphere of 360 ° of air motions.
In the utility model because the reaction force of air-flow when forming the moment of torsion shake the head and rotating from impeller 3, this active force gentle slow continue suitable; And the speed of rotating can be controlled; Therefore significantly alleviate wearing and tearing, prolonged electrical machinery life, energy-conservation and comfortable effect is more outstanding.
In above embodiment, do not reach the safety of narration, and mounting technique, and the employing existing technologies such as other necessary technologies that relate to enforcement, enumerate detailed description no longer successively.
