Abstract

The utility model relates to an oscillating fan with motor-driven. An oscillating link mechanism is driven by an electric motor which is decelerated, via a worm wheel and a worm; rockers of the oscillating link mechanism drive two blades which are fixed on a blade shaft to oscillate for fanning. An electric motor, the worm wheel, the worm, the oscillating link mechanism, etc. are installed in one box casing, via a supporting frame and a machine frame; the two blades are fixed on the blade shaft which extends outside the box casing. The box casing can be hung in space, via a hook. The wind power of the oscillating fan approaches to the wind power of artificial and hand-operated fanning. By the adjustment of the velocity of the electric motor, the dimension of the oscillating link mechanism and the size of the blades, the wind power can be adjusted to be suitable for heat dissipation and cool enjoyment of various people in the state of health.

Description

Oscillating fan with motor-driven

The utility model relates to a kind of electric fan, belongs to the electric fan that relies on blade oscillating to produce wind-force.

Existing electric fan all is to rely on the blade rotation to produce wind-force, good heat dissipation effect, but should not use for a long time, injury is healthy easily, especially to old, the weak and young baby of people, more can not use the electric fan heat radiation easily, torridity summer has to enjoy the cool with manual pectinid.

The purpose of this utility model is the Oscillating fan with motor-driven that a kind of similar manual pectinid effect will be provided.

Utility model is achieved in that on a frame turbine and worm decelerator is housed, and worm screw is accepted electric-motor drive.It is parallel with worm-wheel shaft that a sharf also is housed on the frame, fixing a fork on sharf, fixing a drive link on worm-wheel shaft, and the drive link and the fork other end be a hinged connecting rod respectively.Motor is fixed on the support, and support is connecting frame.Support is installed in the case shell, and sharf stretches out case shell both sides, and symmetry is installed with two fan leafs.When drive link rotates with worm-wheel shaft, make fork make the cycle reciprocally swinging by connecting rod, thereby be with blade oscillating to produce wind-force.This gentle breeze can be regulated by adjusting the electromotor velocity and the size of swing link mechanism and the size of blade according to each one needs.

Below in conjunction with description of drawings structure of the present utility model.

Fig. 1 is the principal mode figure of utility model.

Fig. 2 is the right view of utility model.

With reference to accompanying drawing, motor ［ 1 ］ is fixed on the support ［ 2 ］, and support is installed in the case shell ［ 3 ］. The vertical end connection frame ［ 5 ］ of support is installed with worm and gear on the frame, the axle of worm screw ［ 6 ］ with The axle of motor is being connected by shaft coupling ［ 4 ］. The sharf ［ 12 ］ parallel with worm-wheel shaft ［ 8 ］ is housed below worm-wheel shaft, is fixed wtih drive link ［ 9 ］ at worm-wheel shaft, be fixed wtih fork ［ 11 ］ at sharf, drive link and the articulated connecting rod of the fork other end ［ 10 ］. Make the long sum of length of connecting rod and fork, greater than drive link and sharf to worm-wheel shaft apart from sum, when worm-wheel shaft rotates with drive link, will make fork ［ 11 ］ make periodic reciprocally swinging by connecting rod ［ 10 ］, thereby drive two fan leafs ［ 13 ］ swing pectinid fixing on the sharf. Be fixed on the blade ［ 13 ］ on the siphonal lobe bobbin of case shell both sides, can adopt light thin plate, fabric, artificial leather etc. to make. On the case shell hook is arranged, can arbitrarily hang the locus at needs.

An embodiment of the present utility model: motor power (output) 50W, 1400 rev/mins of rotating speeds.Blade adopts more abundant canvas, and is long 65 centimeters, wide 40 centimeters.Long 4 centimeters of drive link, 8.3 centimeters of length of connecting rod, long 4.2 centimeters of fork, worm-wheel shaft is 8.43 centimeters to the distance of sharf.
